With continuous development of display technologies, a user requires higher about an appearance and performance of a wearable product. To improve user experience for the product, a housing of the wearable product may usually use a metal material, so that the wearable product has a relatively good metallic texture. However, to improve signal quality of an antenna in the wearable product, a metal part in the housing of the wearable product needs to be segmented, and segments of the metal part are connected by using an insulating material. In this way, it is difficult to implement metal integration of the appearance of the product.

<CIT> discloses a kind of metal base, center component and electronic equipment, wherein, a center component includes a center and an antenna radiator, the center includes metal substrate, the antenna radiator is set to the periphery of metal substrate, the antenna radiator is provided with avoiding space, and the avoiding space runs through the antenna radiator.

The object of the present invention is to provide a wearable product, to resolve a problem that metal integration cannot be implemented on a housing of a mobile terminal. This object is solved by the attached independent claim <NUM> and further embodiments and improvements of the invention are listed in the attached dependent claims. Hereinafter, up to the "brief description of the drawings", expressions like ". aspect according to the invention", "according to the invention", or "the present invention", relate to technical teaching of the broadest embodiment as claimed with the independent claims. Expressions like "implementation", "design", "optionally", "preferably", "scenario", "aspect" or similar relate to further embodiments as claimed, and expressions like "example", ". aspect according to an example", "the disclosure describes", or "the disclosure" describe technical teaching which relates to the understanding of the invention or its embodiments, which, however, is not claimed as such.

To achieve the foregoing objectives, the following technical solutions are used in this application:
According to a first aspect according to the invention, the invention provides a wearable product. The wearable product includes a display module, a rear housing, a middle frame, a printed circuit board (printed circuit board, PCB), and a conductive component. The rear housing is located on a non-light-emitting side of the display module. The middle frame is located between the display module and the rear housing. The middle frame includes a metal frame and a plastic frame nested in the metal frame and connected to the metal frame. The metal frame and the plastic frame are both hollow frame structures. The plastic frame is connected to the display module and the rear housing in a sealing manner to form a closed accommodation cavity. The PCB is located in the accommodation cavity. Apart of the conductive component is located in the accommodation cavity and electrically connected to the PCB, and the other part of the conductive component passes through the plastic frame to be electrically connected to the metal frame. It may be learned from the foregoing that, in the wearable product provided in this embodiment of this application, a part that is of the plastic frame located on an inner side of the middle frame and that faces the display module is connected to the display module in a sealing manner. In addition, a part that is of the plastic frame and that faces the rear housing is further connected to the rear housing in a sealing manner. In this way, the plastic frame, the display module, and the rear housing form a complete waterproof structure. The accommodation cavity used for accommodating the PCB is in the waterproof structure. The metal frame connected to the plastic frame is outside the waterproof structure. In this way, there is a risk for water leakage due to relatively small bonding force between the outer metal frame and the inner plastic frame in the middle frame. Based on a waterproof function of the waterproof structure located on an inner side of the metal frame, a probability that external water vapor enters into the waterproof structure can be effectively reduced, thereby reducing a probability of affecting another component in the accommodation cavity of the wearable product, thereby improving waterproof performance of the wearable product. In addition, the metal frame located on an outer side of the middle frame of the wearable product provided in this embodiment of this application is used as an antenna radiator. The metal frame is separated from a component with a metal part in the wearable product by using the plastic frame. In this way, a distance between the metal frame and an inner metal component such as the PCB, that is, antenna clearance can be effectively increased through adjusting a wall thickness of the plastic frame. Greater antenna clearance indicates better antenna performance of the metal frame and better transmission effect of an antenna signal. In addition, the metal frame located on the outer side of the middle frame may be a hollow frame structure whose head and tail are connected. Therefore, for the metal frame, when effective transmission of the antenna signal is met, an appearance of the product may be enabled to meet a requirement for metal integration. In addition, a part of the middle frame is the metal frame, and another part of the middle frame is the plastic frame. Therefore, in comparison with a middle frame fully made of metal, the middle frame provided in this embodiment of this application has a lighter weight, to reduce a weight of the entire wearable product and implement a light design for the entire product.

Optionally, a first through hole is disposed on the plastic frame. The conductive component includes a metal spring, a metal connector, and a first seal kit. The metal spring is in contact with the PCB. One end of the metal connector passes through the first through hole to be in contact with the metal frame, and the other end of the metal connector is in contact with the metal spring. A first annular mounting groove is disposed on a surface that is of a part of the metal connector passing through the first through hole and that cooperates with the first through hole. The first seal kit is located in the first mounting groove and is in contact with a bottom surface of the first mounting groove and a hole wall of the first through hole. In the conductive component, one end of the metal connector is electrically connected to the metal frame, and the other end is electrically connected to the metal spring. The metal spring is electrically connected to the PCB. In this way, the metal frame can be electrically connected to the PCB by using the conductive component, so that the metal frame can be used as an antenna to transmit a signal. In addition, the first seal kit is configured to seal the metal connector and the first through hole. Therefore, an impact from the metal connector passing through the plastic frame can be reduced for the waterproof performance of the waterproof structure including the plastic frame, and the display module and the rear housing connected to the plastic frame.

Optionally, a first connection hole connected to the first through hole is disposed on the metal frame. A part of the metal connector extending through the first through hole is located in the first connection hole and cooperates with the first connection hole. In this case, the part of the metal connector extending through the first through hole may be located in the first connection hole and cooperate with the first connection hole, to increase a contact area between the metal connector and the metal frame.

Optionally, the first connection hole is a threaded hole. The metal connector is a first threaded fastener. The first threaded fastener includes a bare rod and a screw rod that are connected. The bare rod cooperates with the first through hole in a sealing manner, and the screw rod cooperates with the first connection hole in a threaded manner. A diameter of the bare rod is greater than a diameter of the screw rod. In this case, the first seal kit may be mounted in the first mounting groove on the bare rod in the metal connector, and cooperation between the bare rod and the first through hole is implemented in the sealing manner by using the first seal kit. In addition, the screw rod cooperates with the first connection hole in the threaded manner, so that the first threaded fastener can be connected to the metal frame. In addition, in the metal connector, the diameter of the bare rod may be greater than the diameter of the screw rod, so that an intersection face between the bare rod and the screw rod can be in contact with an inner wall that is of the metal frame and that faces the accommodation cavity. In this way, the bare rod is prevented from being screwed into the first connection hole on the metal frame.

Optionally, the first threaded fastener further includes a head. The head is located in the accommodation cavity and connected to the bare rod. The metal spring includes a first sub-spring and a second sub-spring. The first sub-spring is provided with a second through hole. The bare rod passes through the second through hole to fasten the first sub-spring between the head and the plastic frame. The second sub-spring is connected to the first sub-spring to be an integrated structure. The second sub-spring is in contact with the PCB. A diameter of the head in the metal connector is greater than the diameter of the bare rod. Therefore, when the bare rod passes through the first through hole on the plastic frame, the head is located in the accommodation cavity located on an inner side of the plastic frame. In this case, the first sub-spring in the metal spring may be fastened between an inner wall of the plastic frame and the head by using the head, to electrically connect the metal connector to the metal spring. In addition, the second sub-spring that forms the integrated structure with the first sub-spring is in contact with the PCB, so that the metal frame can be electrically connected to the PCB by using the first threaded fastener and the metal spring.

Optionally, the display module includes a display screen and a bezel disposed around a periphery of the display screen. The wearable product further includes an adhesive layer. The adhesive layer is located on a surface that is of the plastic frame and that faces the bezel, and is used to bond the plastic frame and the bezel. In this way, the plastic frame and the bezel are connected by using the adhesive layer, so that the plastic frame is in close contact with the bezel. In this way, a probability that external water vapor enters into the accommodation cavity from a bonding position between the plastic frame and the bezel can be reduced, to improve a waterproof capability of the entire wearable product.

Optionally, a second mounting groove is disposed on a surface that is of the rear housing and that faces the plastic frame. The wearable product further includes a second seal kit. The second seal kit is located in the second mounting groove and is in contact with a surface that is of the plastic frame and that faces the second mounting groove and a bottom surface of the second mounting groove. The second seal kit is configured to seal the plastic frame and the rear housing. The wearable product further includes at least one second threaded fastener. The second threaded fastener is located on a side that is of the second seal kit and that is away from the accommodation cavity. The second threaded fastener passes through the rear housing and the plastic frame to be connected to the display module in a threaded manner. In this way, the rear housing may be connected to the plastic frame in a sealing manner by using the second threaded fastener and the second seal kit located between the rear housing and the plastic frame.

Optionally, a wall thickness of the plastic frame is <NUM> to <NUM>. When the wall thickness of the plastic frame is less than <NUM>, in a nano molding technology, a problem of insufficient molding easily occurs due to relatively few plastic materials. In addition, when the wall thickness of the plastic frame is greater than <NUM>, in a nano molding technology, materials are easily stacked in some regions of the surface of the plastic frame due to so many plastic materials. The regions of the stacked materials shrink, that is, a molding shrinkage phenomenon occurs, thereby reducing quality of the product. Therefore, when the wall thickness of the plastic frame is within the range of <NUM> to <NUM>, in the nano molding technology, a probability that insufficient molding occurs can be reduced, and a probability that molding shrinkage occurs can be reduced.

Optionally, the wearable product further includes a button component. A third through hole is disposed on the middle frame. In addition, the button component includes a button tube and a third seal kit. A part of the button tube is located in the third through hole, and a part of the button tube is located on the outer side of the middle frame. A third annular mounting groove is disposed on a surface that is of the button tube and that cooperates with the third through hole. The third seal kit is located in the third mounting groove and is in contact with a bottom surface of the third mounting groove and a hole wall of a part of the third through hole passing through the plastic frame. The third seal kit is configured to seal the button tube and the third through hole. In this way, the button tube and the plastic frame may be sealed by using the third seal kit. Therefore, an impact from the button tube passing through the plastic frame can be reduced for the waterproof performance of the waterproof structure including the plastic frame, and the display module and the rear housing connected to the plastic frame.

Optionally, the button component further includes a button cap and a button pole. The button cap is nested on a part that is of the button tube and that is located on the outer side of the middle frame. The button pole passes through an inner hole of the button tube and is connected to the button tube and the button cap. The button cap is configured to facilitate a user to control the button component. The button pole is connected to the button cap. The button pole is configured to: when the button cap is pressed or rotated, follow a press or rotation operation on the button cap, so that a component connected to the button pole in the wearable product performs an instruction corresponding to the foregoing operation, to implement control on a watch, for example, adjust time and read information.

Optionally, the inner hole of the button tube includes a first inner sub-hole and a second inner sub-hole that are connected. An aperture of the first inner sub-hole is greater than an aperture of the second inner sub-hole. The first inner sub-hole is disposed near the button cap. A fourth annular mounting groove is disposed on a cylinder surface of a part of the button pole extending into the accommodation cavity. In addition, the button component further includes a spring, a steel sheet, and a clip ring. The spring is mounted on the button pole and located in the first inner sub-hole. When the user presses the button cap, pressure exerted on the button cap causes the spring to be deformed. When the pressure disappears, the button component is reset to a position before the pressure, after the spring is restored from the deformation. The steel sheet is located between the spring and an intersection face between the second inner sub-hole and the first inner sub-hole. The fourth through hole is disposed on the steel sheet for the button pole to pass through. The steel sheet has a large rigidity, to avoid scratching an inner wall of the button tube during the deformation of the spring under the pressure. The clip ring is mounted in the fourth mounting groove. A surface that is of the clip ring and that faces a side wall of the middle frame is in contact with the plastic frame and a side surface of the fourth mounting groove. Therefore, positions of the button pole and the button tube are fixed by using the clip ring.

Optionally, a surface that is of the metal frame and that faces the plastic frame is a first stepped surface. The first stepped surface has at least one first protrusion and at least one first groove. A surface that is of the plastic frame and that faces the metal frame is a second stepped surface. The second stepped surface has at least one second protrusion and at least one second groove. The first protrusion is clamped into the second groove, and the second protrusion is clamped into the first groove, so that the metal frame is connected to the plastic frame.

Optionally, a surface that is of the metal frame and that faces the plastic frame has a plurality of nano-holes. The nano-holes are filled with a part of the plastic frame. An aperture of the nano-hole is at a nano level. In the foregoing nano molding technology, stronger bonding force can be implemented between the metal frame and the plastic frame.

Optionally, a plurality of circuit board feedpoints are disposed on the PCB. The wearable product includes a plurality of conductive components. One conductive component is electrically connected to one circuit board feedpoint. Therefore, parts of the metal frame that are electrically connected to different conductive components may be used to transmit different types of antenna signals.

An embodiment of this application provides a wearable product. The wearable product may be a watch or a band. For ease of description, the following embodiments are described by using an example in which the wearable product is a watch.

As shown in <FIG>, a wearable product <NUM> includes a display module <NUM>, a middle frame <NUM>, and a rear housing <NUM>.

The display module <NUM> has a light-emitting side configured to display a picture and a non-light-emitting side opposite to the light-emitting side. As shown in <FIG>, the rear housing <NUM> is located on the non-light-emitting side of the display module <NUM>.

As shown in <FIG>, the display module <NUM> includes a display screen <NUM> and a bezel <NUM>. The bezel <NUM> is disposed around a periphery of the display screen <NUM>. The bezel <NUM> may protect and decorate the periphery of the display screen <NUM>.

It should be noted that a shape of the display screen <NUM> is not limited in this application. For example, a display surface of the display screen <NUM> may be a circle as shown in <FIG>, or may be a rectangle shown in <FIG>.

When the shape of the display screen <NUM> changes, a shape of another component of the wearable product <NUM>, for example, the bezel <NUM>, the middle frame <NUM>, and the rear housing <NUM>, also changes with the display screen <NUM>. For ease of description, the following is described by using an example in which the display surface of the display screen <NUM> is a circle.

In some embodiments of this application, as shown in <FIG>, the display screen <NUM> may be a liquid crystal display (liquid crystal display, LCD). In this case, the display module <NUM> further includes a backlight unit (backlight unit, BLU) <NUM> that is configured to provide a light source for the liquid crystal display.

Alternatively, in some other embodiments of this application, the display screen <NUM> may be an organic light-emitting diode (organic light emitting diode, OLED) display screen. The OLED display screen can implement independent light emission. Therefore, the BLU <NUM> does not need to be set for the display module <NUM>.

In addition, as shown in <FIG>, the middle frame <NUM> is disposed between the display module <NUM> and the rear housing <NUM>. In this embodiment of this application, as shown in <FIG>, the middle frame <NUM> includes a metal frame <NUM> and a plastic frame <NUM>. The plastic frame <NUM> is nested in the metal frame <NUM> and connected to the metal frame <NUM>. The metal frame <NUM> and the plastic frame <NUM> are both hollow frame structures. Therefore, the entire middle frame <NUM> is also a hollow frame structure.

The metal frame <NUM> is made of a metal material. Therefore, the metal frame <NUM> has conduction performance. The plastic frame <NUM> is made of a plastic material, and has insulation performance.

When the display surface of the display screen <NUM> is a circle, the hollow frame structure may be a ring. The ring is a closed structure whose head and tail are connected.

In some embodiments of this application, in order that the metal frame <NUM> is connected to the plastic frame <NUM>, as shown in <FIG> (a cutaway drawing along a dashed line O2-O2 in <FIG>), a surface that is of the metal frame <NUM> and that faces the plastic frame <NUM> is a first stepped surface A1. A surface that is of the plastic frame <NUM> and that faces the metal frame <NUM> is a second stepped surface A2. The first stepped surface A1 cooperates with the second stepped surface A2.

A partial sectional structure of the metal frame <NUM> and the plastic frame <NUM> is shown in <FIG>. The first stepped surface A1 that is of the metal frame <NUM> and that faces the plastic frame <NUM> has at least one first protrusion <NUM> and at least one first groove <NUM>.

The second stepped surface A2 that is of the plastic frame <NUM> and that faces the metal frame <NUM> has at least one second protrusion <NUM> and at least one second groove <NUM>.

The first protrusion <NUM> is configured to be clamped into the second groove <NUM>, and the second protrusion <NUM> is configured to be clamped into the first groove <NUM>, so that the metal frame <NUM> is connected to the plastic frame <NUM>.

Alternatively, in some other embodiments of this application, the metal frame <NUM> may be combined with the plastic frame <NUM> by using a nano molding technology (nano molding technology, NMT), so that the metal frame <NUM> is connected to the plastic frame <NUM>.

In this case, as shown in <FIG>, a surface that is of the metal frame <NUM> and that faces the plastic frame <NUM> has a plurality of nano-holes <NUM>. The nano-holes <NUM> are filled with a part of the plastic frame <NUM>. An aperture of the nano-hole <NUM> is at a nano level. In the foregoing NMT , stronger bonding force can be implemented between the metal frame <NUM> and the plastic frame <NUM>.

On this basis, in some embodiments of this application, a wall thickness H of the plastic frame <NUM> may be within a range of <NUM> to <NUM>. When the wall thickness H of the plastic frame <NUM> is less than <NUM>, in the nano molding technology, a problem of insufficient molding easily occurs due to relatively few plastic materials.

In addition, when the wall thickness H of the plastic frame <NUM> is greater than <NUM>, in the nano molding technology, materials are easily stacked in some regions of a surface of the plastic frame <NUM> due to so many plastic materials. The regions of the stacked materials shrink, that is, a molding shrinkage phenomenon occurs, thereby reducing quality of the product.

Therefore, when the wall thickness H of the plastic frame <NUM> is within the range of <NUM> to <NUM>, in the nano molding technology, a probability that insufficient molding occurs can be reduced, and a probability that molding shrinkage occurs can be reduced.

In some embodiments of this application, the wall thickness H of the plastic frame <NUM> may be <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, or <NUM>.

It should be noted that the surface that is of the plastic frame <NUM> and that faces the metal frame <NUM> and the surface that is of the plastic frame <NUM> and that is opposite to the metal frame <NUM> are not flat surfaces due to factors such as a manufacturing process or a structure setting. In this case, the wall thickness H of the plastic frame <NUM> may be an average value of straight-line distances between the surface that is of the plastic frame <NUM> and that faces the metal frame <NUM> and the surface that is of the plastic frame <NUM> and that is opposite to the metal frame <NUM>.

In addition, as shown in <FIG> (a cutaway drawing along O1-O1 shown in <FIG>), in some embodiments of this application, in the middle frame <NUM>, a part that is of the plastic frame <NUM> and that faces the display module <NUM> is connected to the display module <NUM> in a sealing manner, and a part that is of the plastic frame <NUM> and that faces the rear housing <NUM> is connected to the rear housing <NUM> in a sealing manner, to form a closed accommodation cavity <NUM>.

The wearable product <NUM> further includes a PCB <NUM> shown in <FIG>. As shown in <FIG>, the PCB <NUM> is disposed in the accommodation cavity <NUM>.

In addition, when the wearable product <NUM> further includes a battery (not shown in the figure), the battery may also be located in the accommodation cavity <NUM>.

On this basis, when the closed accommodation cavity <NUM> has good waterproof performance, a probability that an electronic component such as the PCB <NUM> or the battery located in the accommodation cavity <NUM> encounters water can be reduced, thereby improving waterproof performance of the wearable product <NUM>.

In some embodiments of this application, in order that the part that is of the plastic frame <NUM> and that faces the display module <NUM> is connected to the display module <NUM> in a sealing manner, as shown in <FIG> (a locally enlarged schematic diagram of an E1 position in <FIG>), the wearable product <NUM> further includes an adhesive layer <NUM>.

The adhesive layer <NUM> is located on a surface that is of the plastic frame <NUM> and that faces the bezel <NUM> in the display module <NUM>. The adhesive layer <NUM> is used to bond opposite surfaces of the plastic frame <NUM> and the bezel <NUM>.

In this way, the plastic frame <NUM> and the bezel <NUM> are connected by using the adhesive layer <NUM>, so that the plastic frame <NUM> is in close contact with the bezel <NUM>. In this way, a probability that external water vapor enters into the accommodation cavity <NUM> from a bonding position between the plastic frame <NUM> and the bezel <NUM> can be reduced, to improve a waterproof capability of the entire wearable product <NUM>.

In some other embodiments of this application, in order that the part that is of the plastic frame <NUM> and that faces the rear housing <NUM> is connected to the rear housing <NUM> in a sealing manner, as shown in <FIG>, a second mounting groove <NUM> is disposed on a surface that is of the rear housing <NUM> and that faces the plastic frame <NUM>.

In addition, the wearable product <NUM> further includes a second seal kit <NUM> shown in <FIG> (a locally enlarged schematic diagram of an E2 position in <FIG>).

The second seal kit <NUM> is located in the second mounting groove <NUM> and is in contact with a surface that is of the plastic frame <NUM> and that faces the second mounting groove <NUM> and a bottom surface of the second mounting groove <NUM>. The second seal kit <NUM> is configured to seal the plastic frame <NUM> and the rear housing <NUM>.

It should be noted that in this embodiment of this application, the second seal kit <NUM> may be a seal ring. When the second seal kit <NUM> is a seal ring, because the seal ring is an annular structure whose head and tail are connected, the second mounting groove <NUM> in cooperation with the second seal kit <NUM> is a closed ring groove shown in <FIG>.

On this basis, in order that the plastic frame <NUM> can be connected to the rear housing <NUM>, as shown in <FIG>, the wearable product <NUM> further includes at least one second threaded fastener <NUM>. <FIG> is described by using an example in which the wearable product <NUM> includes four second threaded fasteners <NUM>.

As shown in <FIG> (a cutaway drawing along a dashed line B1-B1 in <FIG>), the second threaded fastener <NUM> is located on a side that is of the second seal kit <NUM> and that is away from the accommodation cavity <NUM>, and the second threaded fastener <NUM> passes through the rear housing <NUM> and the plastic frame <NUM> to be connected to the metal frame <NUM> in a threaded manner.

In this case, in order that the second threaded fastener <NUM> can be connected to the metal frame <NUM> in the threaded manner, as shown in <FIG>, the metal frame <NUM> covers a part of the surface that is of the plastic frame <NUM> and that faces the display module <NUM>. In this way, after passing through the rear housing <NUM> and the plastic frame <NUM>, the second threaded fastener <NUM> can be connected in the screwed manner to the metal frame <NUM> covering the part of the plastic frame <NUM>.

In this case, a through hole for the second threaded fastener <NUM> to pass through is disposed on the rear housing <NUM> and the plastic frame <NUM>, and a threaded hole used for a threaded connection to the second threaded fastener <NUM> is disposed on the metal frame <NUM>.

It should be noted that in some embodiments of this application, the second threaded fastener <NUM> may be a screw, a bolt, or the like.

In this way, the rear housing <NUM> may be connected to the plastic frame <NUM> in a sealing manner by using the second threaded fastener <NUM> and the second seal kit <NUM> located between the rear housing <NUM> and the plastic frame <NUM>.

In this case, when the wearable product <NUM> needs to be repaired or the battery needs to be replaced, the second threaded fastener <NUM> may be taken out, so that the rear housing <NUM> can be dismounted from the middle frame <NUM>, to repair the wearable product <NUM> or replace the battery.

It may be learned from the foregoing that, in the wearable product <NUM> provided in this embodiment of this application, as shown in <FIG>, a part that is of the plastic frame <NUM> located on an inner side of the middle frame <NUM> and that faces the display module <NUM> is connected to the display module <NUM> in a sealing manner. In addition, a part that is of the plastic frame <NUM> and that faces the rear housing <NUM> is further connected to the rear housing <NUM> in a sealing manner. In this way, the plastic frame <NUM>, the display module <NUM>, and the rear housing <NUM> form a complete waterproof structure <NUM>.

The waterproof structure <NUM> includes the plastic frame <NUM>, the display module <NUM>, and the rear housing <NUM>. The accommodation cavity <NUM> used for accommodating the PCB <NUM> is in the waterproof structure <NUM>. The metal frame <NUM> connected to the plastic frame <NUM> is outside the waterproof structure <NUM>.

In this way, there is a risk for water leakage due to relatively small bonding force between the outer metal frame <NUM> and the inner plastic frame <NUM> in the middle frame <NUM>. Based on a waterproof function of the waterproof structure <NUM> located on an inner side of the metal frame <NUM>, a probability that external water vapor enters into the waterproof structure <NUM> can be effectively reduced, thereby reducing a probability of affecting another component in the accommodation cavity <NUM> of the wearable product <NUM>, for example, the PCB <NUM>, thereby improving waterproof performance of the wearable product <NUM>.

In addition, the wearable product <NUM> further includes a conductive component <NUM> shown in <FIG>. A part of the conductive component <NUM> is located in the accommodation cavity <NUM> and electrically connected to the PCB <NUM>, and the other part of the conductive component <NUM> passes through the plastic frame <NUM> to be electrically connected to the metal frame <NUM>. In this way, the metal frame <NUM> on an outer side of the middle frame <NUM> may be used as an antenna of the wearable product <NUM>.

In this case, a signal on the PCB <NUM> can be transmitted to the outer metal frame <NUM> by using the conductive component <NUM>, and the signal on the PCB <NUM> can be sent by using the metal frame <NUM>.

Alternatively, the metal frame <NUM> may receive an external signal and transmit the signal to the PCB <NUM> by using the conductive component <NUM>, so that the PCB <NUM> processes the signal.

In this embodiment of this application, a position in which the PCB <NUM> is electrically connected to the conductive component <NUM> may be referred to as a circuit board feedpoint. A position in which the metal frame <NUM> is electrically connected to the conductive component <NUM> may be referred to as an antenna feedpoint.

For example, in some embodiments of this application, a plurality of circuit board feedpoints are disposed on the PCB <NUM> of the wearable product <NUM>. In this case, the wearable product <NUM> may include a plurality of conductive components <NUM>. One conductive component <NUM> is electrically connected to one circuit board feedpoint on the PCB <NUM>.

For example, as shown in <FIG>, the plurality of conductive components are respectively a conductive component 50a, a conductive component 50b, a conductive component 50c, a conductive component 50d, and a conductive component 50e.

A part that is of the metal frame <NUM> of the middle frame <NUM> and that is electrically connected to the circuit board feedpoint on the PCB <NUM> by using the conductive component 50b may be used as a Bluetooth antenna to transmit a Bluetooth signal.

A part that is of the metal frame <NUM> and that is electrically connected to the circuit board feedpoint on the PCB <NUM> by using the conductive component 50c may be used as a Wi-Fi antenna to transmit a Wi-Fi signal.

A part that is of the metal frame <NUM> and that is electrically connected to the circuit board feedpoint on the PCB <NUM> by using the conductive component 50d may be used as a global positioning system (global positioning system, GPS) antenna to transmit a GPS signal.

A part that is of the metal frame <NUM> and that is electrically connected to the circuit board feedpoint on the PCB <NUM> by using the conductive component 50e may be used as a mobile communications antenna for transmission in mobile communications, for example, a fourth generation communications technology (<NUM>) signal.

On this basis, the metal frame <NUM> protrudes outward to form four convex lugs <NUM> shown in <FIG>. The convex lugs <NUM> are configured to fasten a watch band (not shown in the figure), so that the user conveniently wears the wearable product <NUM>.

In this case, positions in which the conductive component 50b, the conductive component 50c, the conductive component 50d, and the conductive component 50e are electrically connected to the metal frame <NUM>, that is, antenna feedpoints each may be close to one convex lug <NUM> shown in <FIG>. Therefore, transmission of antenna signals in positions of these antenna feedpoints may be improved based on a structural feature of outward protrusion of the convex lugs <NUM>.

In addition, in some embodiments of this application, a part that is of the metal frame <NUM> and that is electrically connected to the circuit board feedpoint on the PCB <NUM> by using the conductive component 50a may be used for grounding.

It may be learned from the foregoing that the metal frame <NUM> located on the outer side of the middle frame <NUM> of the wearable product <NUM> provided in this embodiment of this application is used as an antenna radiator. In addition, the plastic frame <NUM> located the inner side of the middle frame <NUM> is connected to the display module <NUM> and the rear housing <NUM> in a sealing manner to form the closed accommodation cavity <NUM>. The PCB <NUM> and the battery are disposed in the accommodation cavity <NUM>.

In this case, as shown in <FIG>, the metal frame <NUM> is separated from a component with a metal part inside the wearable product <NUM> such as the PCB <NUM> by using the plastic frame <NUM>. In this way, in comparison with a solution shown in <FIG> in which only the metal frame <NUM> is disposed, in a solution shown in <FIG>, a distance between the metal frame <NUM> and an inner metal component such as the PCB <NUM>, that is, antenna clearance can be effectively increased through adjusting a wall thickness H1 of the plastic frame <NUM>.

In this way, greater antenna clearance indicates better antenna performance of the metal frame <NUM> and better transmission effect of an antenna signal, provided that a size requirement for the wearable product <NUM> is met.

In the solution shown in <FIG>, when a size of the wearable product <NUM> is fixed, because the metal frame <NUM> needs to be connected to the display module <NUM> and the rear housing <NUM>, a wall thickness H2 of the metal frame <NUM> cannot be reduced to very thin. Therefore, in the solution shown in <FIG>, it is difficult to obtain good antenna clearance.

It may be learned from the foregoing that a value of the wall thickness H1 of the plastic frame <NUM> may be within a range of <NUM> to <NUM>. On this basis, in some embodiments of this application, as shown in <FIG>, the wall thickness H1 of the plastic frame <NUM> may be about <NUM>. In this way, better antenna clearance can be obtained, and the outer metal frame <NUM> can be supported to some extent.

In addition, the metal frame <NUM> located on the outer side of the middle frame <NUM> is a hollow frame structure, and the hollow frame structure whose head and tail are connected forms a closed structure. It can be learned from the foregoing that good antenna clearance is implemented when the metal frame <NUM> serves as an antenna, to ensure that the wearable product <NUM> has good signal quality of the antenna. Therefore, when effective transmission of the antenna signal is met, the metal frame <NUM> may be further used to enable an appearance of the product to meet a requirement for metal integration. In addition, a part of the middle frame <NUM> is the metal frame <NUM>, and another part of the middle frame is the plastic frame <NUM>. Therefore, in comparison with a middle frame <NUM> fully made of metal, the middle frame <NUM> provided in this embodiment of this application has a lighter weight, to reduce a weight of the entire wearable product <NUM> and implement a light design for the entire product.

It may be learned from the foregoing that, in the wearable product <NUM> provided in this embodiment of this application, as shown in <FIG>, the plastic frame <NUM> in the middle frame <NUM> is connected to the display module <NUM> and the rear housing <NUM> to form the waterproof structure <NUM>. In addition, the wearable product <NUM> further includes some components. These components pass through at least the plastic frame <NUM> in the middle frame <NUM> to be connected to a component in the accommodation cavity <NUM>. In this case, to avoid affecting the waterproof performance of the waterproof structure <NUM>, the following uses different examples to describe in detail a structure of a component passing through at least the plastic frame <NUM> in the middle frame <NUM> and a waterproof setting manner of the component.

In this example, a structure passing through the plastic frame <NUM> is the conductive component <NUM> shown in <FIG>. It may be learned from the foregoing that the part of the conductive component <NUM> is located in the accommodation cavity <NUM> and electrically connected to the PCB <NUM> in the accommodation cavity <NUM>, and the other part of the conductive component <NUM> is electrically connected to the metal frame <NUM>.

In order that the conductive component <NUM> can pass through the plastic frame <NUM>, as shown in <FIG> (a sectional view of a partial structure of the wearable product <NUM>), a first through hole <NUM> is disposed on the plastic frame <NUM>.

As shown in <FIG>, the conductive component <NUM> includes a metal spring <NUM>, a metal connector <NUM>, and a first seal kit <NUM>.

In some embodiments of this application, one end of the metal connector <NUM> passes through the first through hole <NUM> to be in contact with the metal frame <NUM>. The other end of the metal connector <NUM> is in contact with the metal spring <NUM>. The other end of the metal connector <NUM> may be connected to the metal spring <NUM> by using a welding process.

In addition, an end that is of the metal spring <NUM> and that is away from the metal connector <NUM> may be in contact with the circuit board feedpoint on the PCB <NUM> in a welding manner.

The metal connector <NUM> may be a pin. Interference fit may be implemented between the pin and the first through hole <NUM> on the plastic frame <NUM>.

Alternatively, in some other embodiments of this application, to increase a contact area between the metal connector <NUM> and the metal frame <NUM> and improve quality of an antenna signal, as shown in <FIG>, a first connection hole <NUM> connected to the first through hole <NUM> is disposed on the metal frame <NUM>.

To ensure flatness and integrity of an outer surface of the metal frame <NUM>, the first connection hole <NUM> is a blind hole.

In this case, the part of the metal connector <NUM> extending through the first through hole <NUM> may be located in the first connection hole <NUM> and cooperate with the first connection hole <NUM>, to increase the contact area between the metal connector <NUM> and the metal frame <NUM>.

For example, when the metal connector <NUM> is a pin, interference fit can be implemented between the pin and the first connection hole <NUM>.

In addition, to ensure sealing performance between the metal connector <NUM> and the plastic frame <NUM>, as shown in <FIG>, a first annular mounting groove <NUM> is disposed on a surface that is of a part of the metal connector <NUM> passing through the first through hole <NUM> and that cooperates with the first through hole <NUM> on the plastic frame <NUM>.

When the metal connector <NUM> is a pin, the metal connector <NUM> is a pin with the first annular mounting groove <NUM> shown in <FIG>.

On this basis, as shown in <FIG>, the first seal kit <NUM> is located in the first mounting groove <NUM> and is in contact with a bottom surface of the first mounting groove <NUM> and a hole wall of the first through hole <NUM>.

The first seal kit <NUM> is configured to seal the metal connector <NUM> and the first through hole <NUM>. Therefore, an impact from the metal connector <NUM> passing through the plastic frame <NUM> can be reduced for the waterproof performance of the waterproof structure <NUM> including the plastic frame <NUM>, and the display module <NUM> and the rear housing <NUM> connected to the plastic frame <NUM>.

It should be noted that in this embodiment of this application, the first seal kit <NUM> may be a seal ring.

In some other embodiments of this application, as shown in <FIG>, the metal spring <NUM> in the conductive structure <NUM> shown in <FIG> includes a first sub-spring <NUM> and a second sub-spring <NUM> that are connected in an integrated structure. A second through hole <NUM> is disposed on the first sub-spring <NUM>.

In addition, the metal connector <NUM> in the conductive structure <NUM> is a first threaded fastener. The first threaded fastener may be a screw. As shown in <FIG>, the metal connector <NUM> serving as the first threaded fastener includes a head <NUM>, a bare rod <NUM>, and a screw rod <NUM> that are connected.

The first annular mounting groove <NUM> is disposed on the bare rod <NUM>. When the metal connector <NUM> is a screw, the metal connector <NUM> is a screw with the first annular mounting groove <NUM>.

In this case, as shown in <FIG>, in a process of assembling the conductive component <NUM> and the plastic frame <NUM>, the first seal kit <NUM> may be mounted in the first mounting groove <NUM> on the bare rod <NUM> (shown in <FIG>) in the metal connector <NUM>. Then, the metal connector <NUM> passes through the second through hole <NUM> on the first sub-spring <NUM> (shown in <FIG>) in the metal spring <NUM>, and extends into the first through hole <NUM> on the plastic frame <NUM>.

After the conductive component <NUM> and the plastic frame <NUM> are assembled, as shown in <FIG>, a diameter of the head <NUM> of the metal connector <NUM> is greater than a diameter of the bare rod <NUM>. Therefore, when the bare rod <NUM> passes through the first through hole <NUM> (<FIG>) on the plastic frame <NUM>, the head <NUM> is located in the accommodation cavity <NUM> located on an inner side of the plastic frame <NUM>.

In this case, the first sub-spring <NUM> in the metal spring <NUM> may be fastened between an inner wall of the plastic frame <NUM> and the head <NUM> by using the head <NUM>, to electrically connect the metal connector <NUM> to the metal spring <NUM>.

As shown in <FIG>, an end that is away from the first sub-spring <NUM> and that is of the second sub-spring <NUM> that forms the integrated structure with the first sub-spring <NUM> extends into the accommodation cavity <NUM> and is welded to the PCB <NUM>.

In addition, the bare rod <NUM> in the metal connector <NUM> passes through the second through hole <NUM> on the first sub-spring <NUM> in <FIG>, and cooperates with the first through hole <NUM> (<FIG>) on the plastic frame <NUM>. In this case, the first seal kit <NUM> located in the first mounting groove <NUM> on the bare rod <NUM> is in contact with the bottom surface of the first mounting groove <NUM> and the hole wall of the first through hole <NUM>. The first seal kit <NUM> is configured to seal the metal connector <NUM> and the first through hole <NUM>, to improve the waterproof performance of the wearable product <NUM>.

On this basis, the first connection hole <NUM> on the metal frame <NUM> may be a threaded hole. The screw rod <NUM> of the metal connector <NUM> passes through the first through hole <NUM> on the plastic frame <NUM> and cooperates with the first connection hole <NUM> (<FIG>) on the metal frame <NUM> in a threaded manner, so that the metal connector <NUM> is electrically connected to the metal frame <NUM>.

In addition, in the metal connector <NUM>, the diameter of the bare rod <NUM> may be greater than the diameter of the screw rod <NUM>, so that an intersection face between the bare rod <NUM> and the screw rod <NUM> can be in contact with an inner wall that is of the metal frame <NUM> and that faces the accommodation cavity <NUM>. In this way, the bare rod <NUM> is prevented from being screwed into the first connection hole <NUM> (<FIG>) on the metal frame <NUM>.

In conclusion, when the conductive component <NUM> uses the structure shown in <FIG>, in the conductive component <NUM>, one end of the metal connector <NUM> is screwed into the first connection hole <NUM> on the metal frame <NUM> in a threaded connection manner, and the other end of the metal connector <NUM> is connected to the first sub-spring <NUM> fastened between the head <NUM> of the metal connector <NUM> and the plastic frame <NUM>. In addition, the first sub-spring <NUM> and the second sub-spring <NUM> welded to the PCB <NUM> are the integrated structure. In this way, the metal frame <NUM> can be electrically connected to the PCB <NUM> by using the conductive component <NUM>.

In this example, the wearable product <NUM> further includes a button component <NUM> shown in <FIG> (a cutaway drawing along a dashed line A1-A1 in <FIG>).

When a user performs different operations such as a press operation or a rotation operation and the wearable product <NUM> executes an instruction corresponding to these operations, the button component <NUM> may be used to implement control on the watch, for example, adjust time and read information.

The button component <NUM> passes through the middle frame <NUM>. In this case, as shown in <FIG>, a third through hole <NUM> passing through the metal frame <NUM> and the plastic frame <NUM> is disposed on the middle frame <NUM>.

The button component <NUM> includes a button tube <NUM>, a button cap <NUM>, and a button pole <NUM> shown in <FIG>.

Apart of the button tube <NUM> is located in the third through hole <NUM> (<FIG>), and a part of the button tube <NUM> is located on the outer side of the middle frame <NUM>.

The button cap <NUM> is nested on a part that is of the button tube <NUM> and that is located on the outer side of the middle frame <NUM>. The button pole <NUM> passes through an inner hole of the button tube <NUM> and is connected to the button tube <NUM> and the button cap <NUM>.

In this embodiment of this application, the button pole <NUM> and the button cap <NUM> may be an integrated structure that may be formed by using a molding technology.

As shown in <FIG>, the inner hole of the button tube <NUM> includes a first inner sub-hole <NUM> and a second inner sub-hole <NUM> that are connected. An aperture of the first inner sub-hole <NUM> is greater than an aperture of the second inner sub-hole <NUM>. The first inner sub-hole <NUM> is disposed near the button cap <NUM> (<FIG>).

In this case, the button component <NUM> further includes a spring <NUM> and a steel sheet <NUM> shown in <FIG>.

The spring <NUM> is mounted on the button pole <NUM> and located in the first inner sub-hole <NUM> shown in <FIG>. When the user presses the button cap <NUM>, pressure exerted on the button cap <NUM> causes the spring <NUM> to be deformed. When the pressure disappears, the button component <NUM> is reset to a position before the pressure, after the spring <NUM> is restored from the deformation.

The steel sheet <NUM> is located between the spring <NUM> (<FIG>) and an intersection face between the second inner sub-hole <NUM> and the first inner sub-hole <NUM> shown in <FIG>. A fourth through hole (not shown in the figure) for the button pole <NUM> to pass through is disposed on the steel sheet <NUM>.

The steel sheet <NUM> has a large rigidity, to avoid scratching an inner wall of the button tube <NUM> during the deformation of the spring <NUM> under the pressure.

A third annular mounting groove <NUM> shown in <FIG> is disposed on a surface that is of the button tube <NUM> and that cooperates with the third through hole <NUM>.

In this case, the button component <NUM> further includes a third seal kit <NUM>. In a process of assembling the button component <NUM>, as shown in <FIG>, the button pole <NUM> may pass through the inner hole of the button tube <NUM>. In addition, the third seal kit <NUM> is disposed in the third mounting groove <NUM> on an outer surface of the button tube <NUM>.

Then, as shown in <FIG>, the assembled component in <FIG> is mounted in the third through hole <NUM> (<FIG>) on the middle frame <NUM>, so that the third seal kit <NUM> is in contact with a bottom surface of the third mounting groove <NUM> (<FIG>) and a hole wall of a part of the third through hole <NUM> (<FIG>) passing through the plastic frame <NUM>.

In this way, the button tube <NUM> and the plastic frame <NUM> may be sealed by using the third seal kit <NUM>. Therefore, an impact from the button tube <NUM> passing through the plastic frame <NUM> can be reduced for the waterproof performance of the waterproof structure <NUM> including the plastic frame <NUM>, and the display module <NUM> and the rear housing <NUM> connected to the plastic frame <NUM>.

It should be noted that in this embodiment of this application, the third seal kit <NUM> may be a seal ring.

In addition, in order that the button pole <NUM> is connected to the button tube <NUM>, as shown in <FIG>, a fourth annular mounting groove <NUM> is disposed on an outer surface of a part of the button pole <NUM> extending into the accommodation cavity <NUM> on a side that is of the plastic frame <NUM> and that is opposite to the metal frame <NUM>.

In this case, the button component <NUM> further includes a clip ring <NUM> shown in <FIG>. When the button pole <NUM> extends into the accommodation cavity <NUM>, the clip ring <NUM> may be mounted in the fourth mounting groove <NUM>. A surface that is of the clip ring <NUM> and that faces a side wall of the middle frame <NUM> is in contact with the plastic frame <NUM> and a side surface of the fourth mounting groove <NUM>. Therefore, positions of the button pole <NUM> and the button tube <NUM> are fixed by using the clip ring <NUM>.

In addition, to seal the button pole <NUM> and the inner hole of the button tube <NUM>, the button component <NUM> further includes at least one fourth seal kit <NUM> shown in <FIG>. The fourth seal kit <NUM> may be disposed on the button pole <NUM>, and is in contact with a stepped surface formed in an intersection position between the first inner sub-hole <NUM> and the second inner sub-hole <NUM> of the button tube <NUM> (<FIG>).
