One end of the second band body is connected to the second watch clasp, and the other end of the second band body is configured to be connected to the watch face. The second watch clasp is detachably connected to the first watch clasp, so that the watchband can be worn.

The watchband provided in this embodiment of this disclosure has at least the following effect:

The watchband is used in the watch. Because the accommodating space is provided in the first watch clasp, the various electronic devices can be configured in the accommodating space, to extend the function of the watch, so that functionality of the watch is improved.

In an example embodiment, the first watch clasp includes a first housing and a first cover. The first housing is an open housing-shaped mechanical component. A boss is disposed on an inner bottom surface of the first housing. A top of the boss faces an opening of the first housing. A groove is provided on a part that is of the boss and that is away from the inner bottom surface of the first housing, that is, the groove is located on the top of the boss. The first cover is located at the opening of the first housing. The first cover is connected to the boss, and covers a groove opening of the groove, to form the accommodating space between the first cover and the groove. In other words, the accommodating space is formed by covering the first cover on the groove opening of the groove. The accommodating space is located between the first cover and the first housing.

In an example embodiment, a sealing groove is provided around the groove. The first watch clasp further includes a sealing component. The sealing component is located in the sealing groove, and is clamped between the first cover and the boss. In this design, a gap between the first cover and the boss can be sealed through the sealing component, to avoid an impact on the electronic device in the accommodating space caused by dust, liquid, or the like entering the accommodating space.

In an example embodiment, a lock slot is provided on an outer wall of the second watch clasp. The first watch clasp further includes a lock clasp. A first part of the lock clasp is inserted into the first housing and is located on one side of the boss. A second part of the lock clasp is located outside the first housing and is inserted into the lock slot. The lock clasp can move relative to the first housing. In a process of moving the second part of the lock clasp in the lock slot, the lock clasp and the lock slot can be locked or unlocked. In other words, the lock clasp is disposed on the first watch clasp, and the lock slot is provided on the second watch clasp. A detachable connection between the first clasp and the second watch clasp is implemented through fitting between the lock clasp and the lock slot.

In an example embodiment, the lock clasp includes a first sliding block and a first lock arm. A first part of the first sliding block is located in the first housing, and can move relative to the first housing. A second part of the first sliding block is located outside the first housing, and can drive the entire first sliding block to move together. A first part of the first lock arm is connected to the first part of the first sliding block, and is located on a side that is of the first sliding block and that is away from the inner bottom surface of the first housing. A second part of the first lock arm is located outside the first housing. Because the first part of the first lock arm is connected to the first sliding block, the first lock arm can move together by driving the first sliding block. A first notch is provided on a side wall of the second part of the first lock arm, and the first notch is configured to fit a first protrusion. The first protrusion is located on an inner side wall of the lock slot, and is located at a slot opening of the lock slot. The first protrusion faces the first notch. When the first sliding block drives the second part of the first lock arm to move away from a center of the second watch clasp, and the first protrusion is located in the first notch, the lock clasp and the lock slot are mutually locked. When the first sliding block drives the second part of the first lock arm to move toward the center of the second watch clasp, and the first protrusion is located outside the first notch, the lock clasp and the lock slot are mutually unlocked.

In an example embodiment, a first inclined surface is provided on a side that is of the first protrusion and that is close to the slot opening of the lock slot. In a direction toward the center of the second watch clasp, the first inclined surface tilts from the slot opening of the lock slot to a slot bottom. In this design, in the process of inserting the lock clasp into the lock slot, a top of the lock clasp abuts against the first inclined surface, and moves along the first inclined surface, to avoid the first protrusion. In this way, the lock clasp is gradually inserted into the lock slot, and the process of inserting the lock clasp into the lock slot is smoother.

In an example embodiment, a second inclined surface is further provided on the inner side wall of the lock slot. The second inclined surface faces the first inclined surface. In the direction toward the center of the second watch clasp, the second inclined surface tilts from the slot bottom of the lock slot to the slot opening. In this design, in the process of pulling the lock clasp out of the lock slot, the lock clasp moves away from the center of the second watch clasp, so that the top of the lock clasp abuts against the second inclined surface. The lock clasp is pushed out of the lock slot under an action of the second inclined surface, so that the process of pulling the lock clasp out of the lock slot is smoother.

In an example embodiment, the first watch clasp further includes a first elastic component. The first elastic component is located in the first housing, and is compressed between the second part of the lock clasp and the boss. An elastic direction of the first elastic component is the same as a moving direction of the lock clasp. In other words, the first elastic component can apply one acting force to move the lock clasp away from the center of the second watch clasp. In this design, when the lock clasp is in an initial state, under an action of the first elastic component, the lock clasp is located at a position away from the center of the second watch clasp. In the process of inserting the lock clasp into the lock slot, the lock clasp moves toward the center of the second watch clasp under an action of the first inclined surface, and compresses the first elastic component, to avoid the first protrusion. After the first protrusion is avoided, elastic potential energy of the first elastic component is released, to push back the lock clasp away from the center of the second watch clasp. In this case, the first protrusion is inserted into the first notch, so that the lock clasp and the lock slot are locked. In the process of pulling the lock clasp out of the lock slot, the lock clasp moves toward the center of the second watch clasp, and compresses the first elastic component. The lock clasp is pushed out of the lock slot under the action of the second inclined surface, so that the lock clasp and the lock slot are unlocked. After the lock slot is pulled out of the lock slot, the elastic potential energy of the first elastic component is released, to move the lock clasp away from the center of the second watch clasp.

In an example embodiment, the lock clasp includes a drive block, a second sliding block, and a second lock arm. A first part of the drive block is located in the first housing, and can move relative to the first housing. A second part of the drive block is located outside the first housing, and can drive the entire drive block to move together. The second sliding block is inserted into the first housing, and can move relative to the first housing. The second sliding block is in sliding contact with the drive block, and an included angle exists between a moving direction of the second sliding block and a moving direction of the drive block. Therefore, the drive block also pushes the second sliding block to move together when the drive block moves. A first part of the second lock arm is located in the first housing, and is connected to the second sliding block. A second part of the second lock arm is located outside the first housing. Because the first part of the second lock arm is connected to the second sliding block, the second lock arm can move together by driving the second sliding block. A second notch is provided on a side wall of the second part of the second lock arm, and the second notch is configured to fit a second protrusion. The second protrusion is located on the inner side wall of the lock slot, and is located at the slot opening of the lock slot. The second protrusion faces the second notch. When the drive block drives the second sliding block to move the second part of the second lock arm toward the center of the second watch clasp, and the second protrusion is located in the second notch, the lock clasp and the lock slot are mutually locked. When the second sliding block drives the second part of the second lock arm to move away from the center of the second watch clasp, and the second protrusion is located outside the second notch, the lock clasp and the lock slot are mutually unlocked.

In an example embodiment, a third inclined surface is provided on a side that is of the second protrusion and that is close to the slot opening of the lock slot. In a direction away from the center of the second watch clasp, the third inclined surface tilts from the slot opening of the lock slot to the slot bottom. In this design, in the process of inserting the lock clasp into the lock slot, the top of the lock clasp abuts against the third inclined surface, and moves along the third inclined surface, to avoid the second protrusion. In this way, the lock clasp is gradually inserted into the lock slot, and the process of inserting the lock clasp into the lock slot is smoother.

In an example embodiment, a fourth inclined surface is further provided on the inner side wall of the lock slot. The fourth inclined surface faces the third inclined surface. In the direction away from the center of the second watch clasp, the fourth inclined surface tilts from the slot bottom of the lock slot to the slot opening. In this design, in the process of pulling the lock clasp out of the lock slot, the lock clasp moves away from the center of the second watch clasp, so that the top of the lock clasp abuts against the fourth inclined surface. The lock clasp is pushed out of the lock slot under an action of the fourth inclined surface, so that the process of pulling the lock clasp out of the lock slot is smoother.

In an example embodiment, the first watch clasp further includes a second elastic component. The second elastic component is located in the first housing, and is compressed between the second part of the lock clasp and an inner side wall of the first housing. An elastic direction of the second elastic component is the same as a moving direction of the lock clasp. In other words, the second elastic component can apply one acting force to move the lock clasp toward the center of the second watch clasp. In the process of inserting the lock clasp into the lock slot, the lock clasp moves away from a center of a second housing under an action of the third inclined surface, and compresses the second elastic component, to avoid the second protrusion. After the second protrusion is avoided, elastic potential energy of the second elastic component is released, to move the lock clasp toward the center of the second watch clasp. In this case, the second protrusion is inserted into the second notch, so that the lock clasp and the lock slot are locked. In the process of pulling the lock clasp out of the lock slot, the lock clasp moves away from the center of the second watch clasp, and compresses the second elastic component. The lock clasp is pushed out of the lock slot under the action of the fourth inclined surface, so that the lock clasp and the lock slot are unlocked. After the lock slot is pulled out of the lock slot, the elastic potential energy of the second elastic component is released, to push back the lock clasp toward the center of the second watch clasp.

In an example embodiment, a first magnetic component is disposed in the first watch clasp. A second magnetic component is disposed in the second watch clasp, and the second magnetic component and the first magnetic component are attracted to each other. In this design, when the first watch clasp is fastened to the second watch clasp, the first magnetic component and the second magnetic component are attracted to each other. Under effect of this magnetic force, the first watch clasp and the second watch clasp move toward each other, and are mutually locked through fitting between the lock clasp and the lock slot.

According to a second aspect, a watch is provided. The watch includes a watch face, a watchband, and an electronic device. The watchband is the watchband described above. One end of a first band body is connected to a first watch clasp. One end that is of the first band body and that is away from the first watch clasp is connected to the watch face. One end of a second band body is connected to a second watch clasp. One end that is of the second band body and that is away from the second watch clasp is connected to the watch face. The electronic device is located in an accommodating space in the first watch clasp. The electronic device is electrically connected to the watch face through the first band body.

The watch provided in this embodiment of this disclosure has at least the following effect:

Because various electronic devices can be accommodated in the first watch clasp of the watchband, the watch can correspondingly have a plurality of different functions based on different electronic devices, to extend the function of the watch, so that functionality of the watch is improved.

DESCRIPTION OF EMBODIMENTS

Terms used in embodiments of this disclosure are merely used to explain specific embodiments of this disclosure, but are not intended to limit this disclosure.

A smartwatch is an electronic watch. In addition to a timing function of other watches, the smartwatch has a plurality of other functions, such as communication, navigation, and body monitoring.

In a related technology, the smartwatch mainly includes a watch face and a watchband. An electronic device is disposed in the watch face, to implement various functions of the smartwatch. The watchband is connected to the watch face, so that the smartwatch can be bound to a wrist of a user. Currently, there are mainly two forms of watchbands. A body of a first watchband is a metal hinge. One end of the metal hinge is locked or unlocked by using a butterfly clasp. A body of a second watchband is a nylon band. One end of the nylon band is locked or unlocked by using a hook and loop fastener.

However, functions of the foregoing two watchbands are very simple, and only a function of binding the smartwatch to the wrist of the user is provided. This is not conducive to function extension of the smartwatch.

To resolve the foregoing technical problem, an embodiment of this disclosure provides a watchband.FIG.1is a schematic diagram of a structure of the watchband. The watchband includes a first watch clasp1, a second watch clasp2, a first band body3, and a second band body4.

FIG.2is a sectional view ofFIG.1in a direction A-A. With reference toFIG.2, an accommodating space A is provided in the first watch clasp1, and the accommodating space A is used to accommodate an electronic device300. The second watch clasp2is detachably connected to the first watch clasp1. One end of the first band body3is connected to the first watch clasp1, and is configured to be electrically connected to the electronic device300. One end of the second band body4is connected to the second watch clasp2.

The watchband is used in a watch. Because the accommodating space A is provided in the first watch clasp1, various electronic devices300can be configured in the accommodating space A, to extend a function of the watch, so that functionality of the watch is improved.

It can be learned from the foregoing that, the watchband provided in this embodiment of this disclosure is conducive to function extension of a smartwatch because the accommodating space A is provided in the first watch clasp1, and the accommodating space A can accommodate the electronic device300with various functions. The following describes a composition manner of the accommodating space A.

FIG.3is a schematic diagram of a structure of the first watch clasp1.FIG.4is an exploded view of the first watch clasp1. With reference toFIG.3andFIG.4, in this embodiment, the first watch clasp1includes a first housing11and a first cover12.

The first housing11is an open housing-shaped mechanical component. A boss111is disposed on an inner bottom surface of the first housing11. A top of the boss111faces an opening of the first housing11. A groove112is provided on a part that is of the boss111and that is away from the inner bottom surface of the first housing11, that is, the groove112is located on the top of the boss111. The first cover12is located at the opening of the first housing11. The first cover12is connected to the boss111, and covers a groove opening of the groove112, to form the accommodating space A between the first cover12and the groove112.

In the foregoing implementation, the accommodating space A is formed by covering the first cover12on the groove opening of the groove112. The accommodating space A is located between the first cover12and the first housing11. When the electronic device300is disposed in the accommodating space A, the electronic device300is first disposed in the groove112on the top of the boss111, so that the electronic device300is electrically connected to the first band body3. Then, the first cover12covers the groove opening of the groove112, and the first cover12is connected to the boss111, so that the electronic device300is enclosed in the accommodating space A.

Optionally, to ensure accurate assembly between the first cover12and the boss111, a plurality of positioning pins114are disposed on the part that is of the boss111and that is away from the inner bottom surface of the first housing11. The plurality of positioning pins114are arranged at an interval along an outer edge of the boss111. A plurality of positioning openings121are provided on an outer edge of the first cover12. The positioning openings121are in a one-to-one correspondence with the positioning pins114. During assembly, the first cover12first covers the opening of the first housing11, and it is ensured that all positioning pins114are inserted into the corresponding positioning openings121. In this case, the first cover12does not shake unnecessarily under positioning of the positioning pins114. Then, the first cover12is connected to the boss111through a part like a screw.

In addition, the positioning pin114can further implement positioning with the second watch clasp2.FIG.5is a rear view of the second watch clasp. A back side of the second watch clasp is a side that faces the first watch clasp1. A plurality of positioning holes23are provided on an outer wall of the second watch clasp2. The plurality of positioning holes23are arranged at an interval along an outer edge of the second watch clasp2, and are in a one-to-one correspondence with the positioning pins114. After the first housing11and the first cover12are assembled together, one end that is of the positioning pin114and that is away from the boss111passes through the first cover12. After the first watch clasp1and the second watch clasp2are connected together, the positioning pins114can be inserted into the corresponding positioning holes23, avoiding unnecessary shaking between the first watch clasp1and the second watch clasp2.

To ensure a service life of the electronic device300, dustproof and waterproof processing is performed on the electronic device300. Referring again toFIG.4, a sealing groove113is provided around the groove112. The sealing groove113is located at the part that is of the boss111and that is away from the inner bottom surface of the first housing11, namely, the top of the boss111. The first watch clasp1further includes a sealing component13. The sealing component13is located in the sealing groove113, and is clamped between the first cover12and the boss111.

In this design, a gap between the first cover12and the boss111can be sealed through the sealing component13, to avoid an impact on the electronic device300in the accommodating space A caused by dust, liquid, or the like entering the accommodating space A.

For example, the sealing component13is a rubber component. When the first cover12is connected to the boss111, the first cover12also covers the sealing groove113. Because the sealing component13has specific elasticity, the sealing component13is compressed in a space between the sealing groove113and the first cover12, to reliably seal the accommodating space A.

Optionally, because the electronic device300in the accommodating space A is to be electrically connected to the first band body3, the first band body3extends into the accommodating space A. Therefore, there is a notch at each of an edge of the groove112and an edge of the sealing groove113, and the notch of the groove112faces the notch of the sealing groove113. A flexible printed circuit (FPC)31is disposed in the first band body3. One end of the flexible printed circuit31sequentially passes through the notch of the sealing groove113and the notch of the groove112, and is inserted into the accommodating space A, to be electrically connected to the electronic device300. The other end of the flexible printed circuit31is buried in the first band body3, and extends along a length direction of the first band body3, to be electrically connected to a watch face100. To seal the notch of the groove112and the notch of the sealing groove113, parts that are of the sealing component13and that correspond to the two notches fit the two notches. In this way, the two notches can be filled, to achieve sealing effect.

It can be learned from the foregoing that the first watch clasp1is detachably connected to the second watch clasp2. Because the accommodating space A is provided in the first watch clasp1, and occupies some spaces of the first watch clasp1, other connection manners are not applicable to the watchband in this embodiment of this disclosure. To resolve the foregoing technical problem, an embodiment of this disclosure provides a detachable connection manner between the first watch clasp1and the second watch clasp2. This is described below.

FIG.6is a schematic diagram of a disassembled state and an assembled state between the first watch clasp1and the second watch clasp2. With reference toFIG.6, in this embodiment, the first watch clasp1further includes a lock clasp14. The lock clasp14is connected to the first housing11and can move relative to the first housing11, and the lock clasp14is located on one side of the boss111. A lock slot21is provided on the outer wall of the second watch clasp2. A part that is of the lock clasp14and that is away from the first housing11is inserted into the lock slot21, so that the lock clasp14and the lock slot21are locked or unlocked.

In the foregoing implementation, the first housing11provides an assembly basis for a first part of the lock clasp14. Therefore, the first part of the lock clasp14can move relative to the first housing11. To be specific, a second part of the lock clasp14can move relative to the first housing11together with the first part. In addition, because the lock clasp14is located on one side of the boss111, the lock clasp14does not interfere with the boss111, that is, does not affect the accommodating space A located on the top of the boss111. When the lock clasp14is inserted into the lock slot21, the lock clasp14and the lock slot21can be mutually locked or unlocked by moving the second part of the lock clasp14. In other words, the lock clasp14is disposed on the first watch clasp1, and the lock slot21is provided on the second watch clasp2. A detachable connection between the first clasp and the second watch clasp2is implemented through fitting between the lock clasp14and the lock slot21.

In this embodiment, two fitting manners between the lock clasp14and the lock slot21are provided. The following separately describes the two fitting manners.

FIG.6mentioned above is the first fitting manner between the lock clasp14and the lock slot21.FIG.7is a schematic diagram of a locked state between the lock clasp14and the lock slot21in this fitting manner.FIG.8is a schematic diagram of an unlocked state between the lock clasp14and the lock slot21in this fitting manner.

With reference toFIG.7andFIG.8, in this embodiment, the second part of the lock clasp14is located between an edge part and a central part of the second watch clasp2. When the second part of the lock clasp14is located at a first position in the lock slot21, the second part of the lock clasp14is close to the edge part of the second watch clasp2, and the second part of the lock clasp14and the lock slot21are mutually locked. When the second part of the lock clasp14is located at a second position in the lock slot21, the second part of the lock clasp14is close to the central part of the second watch clasp2, and the second part of the lock clasp14and the lock slot21are mutually unlocked.

To be specific, in this fitting manner of the lock clasp14and the lock slot21, when a user operates the lock clasp14, if the lock clasp14and the lock slot21are to be locked, the lock clasp14moves toward the edge part of the second watch clasp2; or if the lock clasp14and the lock slot21are to be unlocked, the lock clasp14moves toward the central part of the second watch clasp2. In this way, the lock clasp14and the lock slot21are locked or unlocked.

For example, in this embodiment, the second watch clasp2is circular. In this case, the edge part of the second watch clasp2is a part close to an edge of the circle, and the central part of the second watch clasp2is a part close to a center of the circle. In another embodiment, the second watch clasp2is square. In this case, the edge part of the second watch clasp2is a part close to an edge of the square, and the central part of the second watch clasp2is a part close to a diagonal intersection point of the square. It is easy to understand that the shape of the second watch clasp2is merely used as an example, and the shape of the second watch clasp2is not limited in this disclosure.

It should be noted that, in a process of fitting the first watch clasp1and the second watch clasp2, in a horizontal direction (in a plane direction in which the first watch clasp1is fastened to the second watch clasp2), the edge part of the second watch clasp2corresponds an edge part of the first watch clasp1, namely, a position away from the boss111. The central part of the second watch clasp2corresponds a central part of the first watch clasp1, namely, a position close to the boss111. In other words, when the second part of the lock clasp14is located at the first position in the lock slot21, the first part of the lock clasp14is correspondingly located at a first position in the first housing11. When the second part of the lock clasp14is located at the second position in the lock slot21, the second part of the lock clasp14is correspondingly located at a second position in the first housing11. In addition, in a process in which the second part of the lock clasp14moves between the first position and the second position, the first part of the lock clasp14moves between an edge part of the first housing11and the boss111. In this case, the lock clasp14does not interfere with the boss111and does not affect the accommodating space A located on the top of the boss111.

FIG.9is a schematic diagram of assembly of the lock clasp14. A solid arrow inFIG.9is a moving direction of the lock clasp14. With reference toFIG.9, in this embodiment, the lock clasp14includes a first sliding block141and a first lock arm142. A first part of the first sliding block141is located in the first housing11, a second part of the first sliding block141is located outside the first housing11, and the first sliding block141can move relative to the first housing11. A first part of the first lock arm142is connected to the first part of the first sliding block141, and is located on a side that is of the first sliding block141and that is away from the inner bottom surface of the first housing11, a second part of the first lock arm142is located outside the first housing11, and a first notch143is provided on a side wall of the second part of the first lock arm142.

Because the second part of the first sliding block141is located outside the first housing11, the user can drive, by moving the second part of the first sliding block141, the first part of the first sliding block141located in the first housing11to move. In addition, because the first end of the first lock arm142is connected to the first part of the first sliding block141, the first lock arm142also moves together in a process of moving the first sliding block141.

With reference toFIG.7andFIG.8, a first protrusion211is provided on an inner side wall of the lock slot21, the first protrusion211is located at a slot opening of the lock slot21, and the first protrusion211faces the first notch143.

When the first sliding block141drives the second part of the first lock arm142to move away from the center of the second watch clasp2, and the first protrusion211is located in the first notch143, the lock clasp14and the lock slot21are mutually locked. When the first sliding block141drives the second part of the first lock arm142to move toward the center of the second watch clasp2, and the first protrusion211is located outside the first notch143, the lock clasp14and the lock slot21are mutually unlocked.

It should be noted that, with reference toFIG.7andFIG.8, when the first protrusion211is inserted into the first notch143, the lock clasp14and the lock slot21are locked. This means that the lock clasp14cannot be directly pulled out of the lock slot21in a direction from a slot bottom of the lock slot21to the slot opening. When the first protrusion211is located outside the first notch143, the lock clasp14and the lock slot21are unlocked. This means that the lock clasp14can be directly pulled out of the lock slot21in the direction from the slot bottom of the lock slot21to the slot opening.

Still with reference toFIG.7andFIG.8, to make the process of inserting the lock clasp14into the lock slot21smoother, in this embodiment, a first inclined surface212is provided on a side that is of the first protrusion211and that is close to the slot opening of the lock slot21. In a direction toward the center of the second watch clasp2, the first inclined surface212tilts from the slot opening of the lock slot21to the slot bottom. In this design, in the process of inserting the lock clasp14into the lock slot21, a top of the lock clasp14abuts against the first inclined surface212, and moves from the first position to the second position along the first inclined surface212, to avoid the first protrusion211. In this way, the lock clasp14is gradually inserted into the lock slot21, and the process of inserting the lock clasp14into the lock slot21is smoother.

Correspondingly, to make the process of pulling the lock clasp14out of the lock slot21smoother, a second inclined surface213is further provided on the inner side wall of the lock slot21. The second inclined surface213faces the first inclined surface212. In the direction toward the center of the second watch clasp2, the second inclined surface213tilts from the slot bottom of the lock slot21to the slot opening. In this design, in the process of pulling the lock clasp14out of the lock slot21, the lock clasp14moves from the first position to the second position, so that the top of the lock clasp14abuts against the second inclined surface213. The lock clasp14is pushed out of the lock slot21under an action of the second inclined surface213, so that the process of pulling the lock clasp14out of the lock slot21is smoother.

Still with reference toFIG.7andFIG.8, to ensure that the lock clasp14can be securely locked in the lock slot21, in this embodiment, the first watch clasp1further includes a first elastic component15. The first elastic component15is located in the first housing11, and is compressed between the second part of the lock clasp14and the boss111. An elastic direction of the first elastic component15is the same as the moving direction of the lock clasp14. In other words, the first elastic component15can apply one acting force to move the lock clasp14toward the first position.

FIG.10is a schematic diagram of an assembly process between the first watch clasp1and the second watch clasp2. A hollow arrow means an assembly sequence, and a solid arrow means a moving direction of a component.FIG.11is a schematic diagram of a disassembly process between the first watch clasp1and the second watch clasp2. A hollow arrow means an assembly sequence, and a solid arrow mean the moving direction of the component. With reference toFIG.10andFIG.11, the following describes the assembly process and disassembly process between the first watch clasp1and the second watch clasp2under an action of the first elastic component15.

When the lock clasp14is in an initial state (the lock clasp14and the lock slot21are unlocked), the lock clasp14is located at the first position under the action of the first elastic component15(refer to an upper view inFIG.10). In the process of inserting the lock clasp14into the lock slot21, the top of the first lock arm142abuts against the first inclined surface212. Under an action of the first inclined surface212, the lock clasp14moves from the first position to the second position, and compresses the first elastic component15, to avoid the first protrusion211(refer to a middle view inFIG.10). After the first protrusion211is avoided, elastic potential energy of the first elastic component15is released, to drive the lock clasp14from the second position to the first position. In this case, the first protrusion211is inserted into the first notch143, so that the lock clasp14and the lock slot21are locked (refer to a lower view inFIG.10).

When the lock clasp14is in an initial state (the lock clasp14and the lock slot21are locked), the lock clasp14is located at the first position under the action of the first elastic component15(refer to an upper view inFIG.11). In the process of pulling the lock clasp14out of the lock slot21, the lock clasp14moves from the first position to the second position, and compresses the first elastic component15until the top of the first lock arm142abuts against the second inclined surface213(refer to a middle view inFIG.11). Under the action of the second inclined surface213, the lock clasp14is gradually pushed out of the lock slot21, so that the lock clasp14and the lock slot21are unlocked (refer to a lower view inFIG.11). After the lock slot21is pulled out of the lock slot21, the elastic potential energy of the first elastic component15is released, to drive the lock clasp14from the second position to the first position. In this case, the lock clasp14is reset, to wait for a next locking operation.

FIG.12is the second fitting manner between the lock clasp14and the lock slot21. Similarly, the lock clasp14is inserted into the lock slot21, so that the lock clasp14and the lock slot21are locked. The lock clasp14is pulled out of the lock slot21, so that the lock clasp14and the lock slot21are unlocked. Main differences lie in different driving manners for the lock clasp14, and different positions of a first position and a second position. This is described below.

FIG.13is a schematic diagram of a locked state between the lock clasp14and the lock slot21in this fitting manner.FIG.14is a schematic diagram of an unlocked state between the lock clasp14and the lock slot21in this fitting manner.

With reference toFIG.13andFIG.14, in this embodiment, a second part of the lock clasp14is located between an edge part and a central part of the second watch clasp2. When the second part of the lock clasp14is located at a first position in the lock slot21, the second part of the lock clasp14is close to the central part of the second watch clasp2, and the second part of the lock clasp14and the lock slot21are mutually locked. When the second part of the lock clasp14is located at a second position in the lock slot21, the second part of the lock clasp14is close to the edge part of the second watch clasp2, and the second part of the lock clasp14and the lock slot21are mutually unlocked.

To be specific, in this fitting manner of the lock clasp14and the lock slot21, when a user operates the lock clasp14, if the lock clasp14and the lock slot21are to be locked, the lock clasp14moves toward the central part of the second watch clasp2, or if the lock clasp14and the lock slot21are to be unlocked, the lock clasp14moves toward the edge part of the second watch clasp2. In this way, the lock clasp14and the lock slot21are locked or unlocked.

In addition, in a process in which the second part of the lock clasp14moves between the first position and the second position, a first part of the lock clasp14moves between an edge part of a first housing11and a boss111. In this case, the lock clasp14does not interfere with the boss111and does not affect an accommodating space A located on a top of the boss111.

FIG.15is an exploded view of the first watch clasp1.FIG.16is a schematic diagram of assembly of the lock clasp14. A solid arrow inFIG.16is a moving direction of the lock clasp14. With reference toFIG.15andFIG.16, in this embodiment, the lock clasp14includes a drive block144, a second sliding block145, and a second lock arm146. A first part of the drive block144is located in the first housing11, a second part of the drive block144is located outside the first housing11, and the drive block144can move relative to the first housing11. The second sliding block145is movably inserted into the first housing11, and is in sliding contact with the drive block144. An included angle exists between the moving direction of the second sliding block145and a moving direction of the drive block144. A first part of the second lock arm146is connected to a first part of the second sliding block145, and is located on a side that is of the second sliding block145and that is away from an inner bottom surface of the first housing11. A second part of the second lock arm146is located outside the first housing11, and a second notch147is provided on a side wall of the second part of the second lock arm146.

Because the second part of the drive block144is located outside the first housing11, the user can drive, by moving the second part of the drive block144, the first part of the drive block144located in the first housing11to move. In addition, the first part of the drive block144is in contact with the second sliding block145, and the second lock arm146is connected to the second sliding block145. Therefore, the second lock arm146also moves together in a process of moving the drive block144.

In the foregoing implementation, there is an extrusion inclined surface on a side of the moving direction of the drive block144. An included angle of 45° exists between the extrusion inclined surface and the moving direction of the drive block144. There is an extrusion inclined surface on a side of the moving direction of the second sliding block145. An included angle of 45° exists between the extrusion inclined surface and the moving direction of the second sliding block145. The extrusion inclined surface of the drive block144slidably fits with the extrusion inclined surface of the second sliding block145. When the drive block144moves, under an action of the two extrusion inclined surfaces, a part of acting force, applied by the drive block144to the second sliding block145, changes to a component force perpendicular to the moving direction of the drive block144. The component force can drive the second sliding block145to move along the moving direction perpendicular to the drive block144.

With reference toFIG.13andFIG.14, a second protrusion214is provided on an inner side wall of the lock slot21. The second protrusion214is located at a slot opening of the lock slot21, and the second protrusion214faces the second notch147.

When the drive block144drives the second sliding block145to move the second part of the second lock arm146toward a center of the second watch clasp2, and the second protrusion214is located in the second notch147, the lock clasp14and the lock slot21are mutually locked. When the second sliding block145drives the second part of the second lock arm146to move away from the center of the second watch clasp2, and the second protrusion214is located outside the second notch147, the lock clasp14and the lock slot21are mutually unlocked.

Still with reference toFIG.13andFIG.14, to make the process of inserting the lock clasp14into the lock slot21smoother, in this embodiment, a third inclined surface215is provided on a side that is of the second protrusion214and that is close to the slot opening of the lock slot21. In a direction away from the center of the second watch clasp2, the third inclined surface215tilts from the slot opening of the lock slot21to a slot bottom. In this design, in the process of inserting the lock clasp14into the lock slot21, a top of the lock clasp14abuts against the third inclined surface215, and moves from the first position to the second position along the third inclined surface215, to avoid the second protrusion214. In this way, the lock clasp14is gradually inserted into the lock slot21, and the process of inserting the lock clasp14into the lock slot21is smoother.

Correspondingly, to make the process of pulling the lock clasp14out of the lock slot21smoother, a fourth inclined surface216is further provided on the inner side wall of the lock slot21. The fourth inclined surface216faces the third inclined surface215. In the direction away from the center of the second watch clasp2, the fourth inclined surface216tilts from the slot bottom of the lock slot21to the slot opening. In this design, in the process of pulling the lock clasp14out of the lock slot21, the lock clasp14moves from the first position to the second position, so that the top of the lock clasp14abuts against the fourth inclined surface216. The lock clasp14is pushed out of the lock slot21under an action of the fourth inclined surface216, so that the process of pulling the lock clasp14out of the lock slot21is smoother.

Still with reference toFIG.13andFIG.14, to ensure that the lock clasp14can be securely locked in the lock slot21, in this embodiment, the first watch clasp1further includes a second elastic component16.

The second elastic component16is located in the first housing11, and is compressed between the second part of the lock clasp14and an inner side wall of the first housing11. An elastic direction of the second elastic component16is the same as the moving direction of the lock clasp14. In other words, the second elastic component16can apply one acting force to move the lock clasp14toward the first position.

FIG.17is a schematic diagram of an assembly process between the first watch clasp1and the second watch clasp2. A hollow arrow means an assembly sequence, and a solid arrow means a moving direction of a component.FIG.18is a schematic diagram of a disassembly process between the first watch clasp1and the second watch clasp2. A hollow arrow means an assembly sequence, and a solid arrow mean the moving direction of the component. With reference toFIG.17andFIG.18, the following describes the assembly process and disassembly process between the first watch clasp1and the second watch clasp2under an action of the second elastic component16.

When the lock clasp14is in an initial state (the lock clasp14and the lock slot21are unlocked), the lock clasp14is located at the first position under the action of the second elastic component16(refer to an upper view inFIG.17). In the process of inserting the lock clasp14into the lock slot21, the top of the second lock arm146abuts against the third inclined surface215. Under an action of the third inclined surface215, the lock clasp14moves from the first position to the second position, and compresses the second elastic component16, to avoid the second protrusion214(refer to a middle view inFIG.17). After the second protrusion214is avoided, elastic potential energy of the second elastic component16is released, to drive the lock clasp14from the second position to the first position. In this case, the second protrusion214is inserted into the second notch147, so that the lock clasp14and the lock slot21are locked (refer to a lower view inFIG.17).

When the lock clasp14is in an initial state (the lock clasp14and the lock slot21are locked), the lock clasp14is located at the first position under the action of the second elastic component16(refer to an upper view inFIG.18). In the process of pulling the lock clasp14out of the lock slot21, the lock clasp14moves from the first position to the second position, and compresses the second elastic component16until the top of the second lock arm146abuts against the fourth inclined surface216(refer to a middle view inFIG.18). Under the action of the fourth inclined surface216, the lock clasp14is gradually pushed out of the lock slot21, so that the lock clasp14and the lock slot21are unlocked (refer to a lower view inFIG.18). After the lock slot21is pulled out of the lock slot21, the elastic potential energy of the second elastic component16is released, to drive the lock clasp14from the second position to the first position. In this case, the lock clasp14is reset, to wait for a next locking operation.

FIG.19is an exploded view of the first watch clasp1and the second watch clasp2. With reference toFIG.19, in this embodiment, a first magnetic component17is disposed in the first watch clasp1. A second magnetic component22is disposed in the second watch clasp2, and the second magnetic component22and the first magnetic component17are attracted to each other. In this design, when the first watch clasp1is fastened to the second watch clasp2, the first magnetic component17and the second magnetic component22are attracted to each other. Under effect of this magnetic force, the first watch clasp1and the second watch clasp2automatically move toward each other, and are mutually locked through fitting between the lock clasp14and the lock slot21.

FIG.20is a schematic diagram of a structure of a watch according to an embodiment of this disclosure. Refer toFIG.20. The watch is a smartwatch, and includes a watch face100, a watchband200, and an electronic device300.

The watchband200is the watchband shown inFIG.1toFIG.19. One end of a first band body3that is away from a first watch clasp1is connected to the watch face100. One end of a second band body4that is away from a second watch clasp2is connected to the watch face100. The electronic device300is located in an accommodating space A (refer toFIG.21), and is electrically connected to the watch face100through the first band body.

Because various electronic devices300can be accommodated in the first watch clasp1of the watchband200, the watch can correspondingly have a plurality of different functions based on different electronic devices300, to extend the function of the watch, so that functionality of the watch is improved.
