Patent Description:
In a single-lens reflex camera, a variable aperture used to adjust an amount of light entering the camera has a plurality of levels, and the amount of light entering the camera may be adjusted, to meet brightness requirements of the camera in different conditions. Installation of the aperture in a lens needs to be highly precise, to obtain a high-quality image.

With development of science and technology, electronic devices such as a mobile phone and a tablet computer have an increasingly higher requirement on an image shooting function, to achieve an image shooting effect close to an image shooting effect of the single-lens reflex camera. However, currently, an assembly manner of an aperture and a lens is difficult, and is difficult to be applied to such small electronic devices.

A printed circuit assembly positioned on the lens carrier is electrically coupled to suspension wires. The printed circuit assembly includes a printed circuit that has installed thereon a serial bus communications interface circuit that is to receive the commands from the controller through one of the suspension wires, and a translation circuit that is to translate the commands into control signals that are to operate or drive the optical path modifiers via the electrical components and according to the commands, respectively.

Document <CIT> describes a camera module which includes: a housing including a lens module; an aperture module disposed on the lens module and configured to form an incidence hole having various sizes through a plurality of blades; and an aperture driving part including a magnet unit including a driving magnet facing a driving coil. The magnet unit is configured to linearly reciprocate. A first blade among the plurality of blades is connected to the magnet unit and is connected to remaining blades among the plurality of blades by a gear to transmit driving force from the magnet unit to the remaining blades.

This disclosure provides camera modules and an electronic device, to meet a high-quality imaging requirement of a small electronic device.

The present invention is set out by the set of appended claims. In the following, parts of the description and drawing referring to implementations or examples, which are not covered by the claims are not presented as embodiments of the invention, but as illustrative examples useful for understanding the invention.

This disclosure discloses a camera module that can be applied to an electronic device such as a mobile phone or a tablet computer. The camera module is integrated with a variable aperture, and can meet a higher image shooting requirement of this type of electronic device. The camera module specifically includes a camera motor, a lens, an image sensor assembly, and a variable aperture. The camera motor includes a focusing part, and the focusing part is configured to drive the lens to move in an optical axis direction, to meet a focusing requirement of image shooting. Specifically, the focusing part includes a base, a carrier, and a driver. The base is equivalent to a fixing part and provides support for another structure, and the carrier is equivalent to a movable part. The driver is fastened on the carrier, and is configured to drive the carrier to move relative to the base in a specified direction, where the specified direction is the optical axis direction of the lens. In the specified direction, the carrier forms an installation hole. The lens is fastened in the installation hole of the carrier, and may move in the optical axis direction with the carrier to implement focusing. The lens has a light incoming side, the variable aperture is fastened on the carrier and is located on the light incoming side of the lens. The variable aperture has a light incoming hole, and a diameter of the light incoming hole is adjustable. External light enters the lens after being adjusted by using the variable aperture. The image sensor assembly is disposed on a light emission side of the lens. Specifically, the image sensor assembly is fastened on the base, and light passing through the lens finally arrives at the image sensor assembly for imaging. The image sensor assembly herein may include an image sensor, another external connection assembly, and a support structure.

Both of the variable aperture and the lens in the camera module are disposed on the carrier of the focusing part, the variable aperture and the lens can simultaneously move in the optical axis direction to implement focusing, and the variable aperture is independent of the lens. This reduces assembly difficulty of the camera module and facilitates miniaturization of the camera module. In this way, the camera module can be applied to a small electronic device such as a mobile phone. In addition, adjustment of the variable aperture on the light incoming hole may not be affected by movement of the lens, and a higher-quality image shooting requirement is met.

Because both of the lens and the variable aperture are fastened on the carrier of the focusing part, and the variable aperture also needs to be disposed on the light incoming side of the lens, a support part for bearing the variable aperture is disposed on the carrier, and the variable aperture may be fastened on the support part, to facilitate fastening and installation. The support part herein may protrude from the camera motor. Certainly, the support part needs to be adjusted based on a size of the lens, to meet an installation requirement of the lens and the variable aperture.

In a possible implementation, the camera motor may further include a top cover and a stabilization part. The top cover and the stabilization part cooperate up and down to form accommodation space used to accommodate the focusing part. The focusing part may be specifically fastened to the stabilization part. When the camera module is used, the image stabilization part may drive the lens to move in a plane perpendicular to the optical axis. Therefore, adverse impact of shaking of the camera module on imaging quality during use is reduced. Certainly, a first optical hole for light to pass through needs to be opened on the top cover, and an axis of the first optical hole is collinear with an optical axis.

In a possible implementation, the driver in the focusing part may include a drive coil and a drive magnet. The drive coil is disposed on the carrier, and the drive magnet is correspondingly disposed on the base. In this way, the drive coil is opposite to the drive magnet, the drive coil is powered on, the drive coil generates an electric field, and the drive magnet is located in the electric field and can be driven to move. Movement of the drive magnet may be adjusted by changing a magnitude and a direction of a current in the drive coil. It may be understood that the drive magnet is disposed on the base, and the drive coil is disposed on the base, to limit a form of relative driving between the drive magnet and the drive coil. In other words, the drive magnet is equivalent to a fixed end, and the drive coil is equivalent to a movable end. Therefore, the drive magnet may alternatively be disposed on another structure, for example, a top cover that is relatively fastened to the base.

In the camera module provided in this disclosure, the variable aperture is independent of the lens, and may be used independently. Specifically, the variable aperture may include a drive structure and a plurality of blades. The plurality of blades are disposed in an annular manner to form a light incoming hole for light to pass through the lens. The drive structure is configured to drive the plurality of blades to move to change a size of the light incoming hole. Therefore, an amount of light passing through the lens is adjusted. When the variable aperture is used independently, a power supply is added to the drive structure, so that the drive structure can drive the blades to move to change the size of the light incoming hole.

The focusing part further includes a control assembly used as a control apparatus. The control assembly is specifically fastened on the base. The control assembly is electrically connected to the driver to control an action of the driver. The control assembly is electrically connected to the drive structure of the variable aperture by using the connection assembly, to control the drive structure to adjust the size of the light incoming hole of the variable aperture.

Therefore, the control assembly herein is connected to the drive structure of the variable aperture by using a signal, and the connection assembly is used as a structure for electrical signal conduction between the variable aperture and the control assembly.

The connection assembly comprises a first spring. The first spring is disposed on a side that is of the carrier and that faces the variable aperture. The first spring is made of a metal material, which may be specifically copper or copper alloy. The first spring is electrically connected to the control assembly and the drive structure of the variable aperture, so that the control assembly is connected to an electrical signal of the variable aperture.

Alternatively, the connection assembly is implemented by using a connection circuit formed by a combination of first springs on the carrier. The connection circuit may be formed by directly cabling on the carrier, or may be formed by attaching a flexible circuit board to the carrier. The drive structure of the variable aperture is electrically connected to the connection circuit. The first spring herein is similar to the foregoing first spring, and is disposed on a side that is of the carrier base and that faces the variable aperture. A difference lies in that the first spring herein is electrically connected to the control assembly, and is electrically connected to the connection circuit on the carrier. Therefore, in this manner, electrical signals between the drive structure of the variable aperture and the control assembly are jointly implemented by using the first spring and the connection circuit on the carrier.

In the foregoing two implementations, the first spring serves as a carrier for transmitting at least a part of electrical signals between the control assembly and the drive structure of the variable aperture. To enhance an electrical signal transfer effect, the first spring may be divided into a plurality of sub-springs disposed on a same layer based on a specific structure of the first spring. For example, the plurality of sub-springs may be distributed annularly around an optical axis by using the optical axis as a center.

It should be noted that, in addition to being used as an electrical signal carrier, the first spring may alternatively be used as a connector between the carrier and the fixing part (for example, the base, the image stabilization part, or the top cover) of the camera module. Herein, the first spring may be connected between the carrier and the top cover. Corresponding to the first spring, a second spring may be further disposed on a side that is of the carrier and that faces the image sensor assembly, and the second spring may connect the carrier and the base. Because the first spring and the second spring are respectively located on two sides of the carrier, and the first spring and the second spring exert a function in opposite directions on the carrier from two opposite directions. In this way, the carrier is equivalent to being in a relatively stable state. Certainly, because of elastic characteristics of the first spring and the second spring, the carrier may still be driven by the driver to move relative to the base.

In the foregoing two implementations, because the first spring serves as a carrier for transmitting at least a part of electrical signals, the first spring belongs to an electrical connection structure. It should be considered that another electrical device (for example, the drive coil and the drive magnet in the driver) is further disposed on the camera module provided in this disclosure. To prevent mutual interference between the first spring and this type of electrical device, an insulation isolation structure may be sandwiched between the first spring and this type of structure. Specifically, a spacer may be sandwiched between the first spring and the drive magnet, and the carrier may serve as an insulation isolation structure between the first spring and the drive coil. Certainly, a structure of the spacer is not limited, and may be a flat plate or a baffle plate. Certainly, a location at which the insulation isolation structure is disposed relative to the first spring may be determined based on relative locations of other electrical devices. This is not limited herein.

In consideration of structural integrity, the focusing part may further include a housing, and the housing cooperates with the base up and down to form accommodating space for accommodating the carrier and the driver. Certainly, the first spring and the second spring are also accommodated, and a spacing frame may be further sandwiched between the housing and the first spring to implement an isolation function.

Based on the foregoing technical solutions, this disclosure further discloses an electronic device. The electronic device may be a mobile phone or a tablet computer. Specifically, a camera module is installed on a device body, to implement an image shooting function. The camera module has an aperture that can be adjusted in a plurality of levels, to meet a higher image shooting requirement.

In a single-lens reflex camera, a variable aperture is a structure that can be used with a shutter to adjust an amount of light passing through the camera. Currently, the variable aperture applied to the single-lens reflex camera is generally installed in a lens. This imposes a highly difficult requirement on assembly of a camera module. Therefore, the camera module having the variable aperture cannot be directly used in electronic devices such as a mobile phone and a tablet computer. Therefore, this disclosure provides a camera module, so that a structure of the lens is independent of a structure of the variable aperture when the lens moves synchronously with the variable aperture in focus adjustment. Therefore, assembly difficulty of the camera module is reduced. Based on this structure, a lighter and thinner camera module can be more easily designed. Therefore, the camera module may be applied to a small electronic device, to meet increasingly improved imaging quality required by the small electronic device. It may be understood that the electronic device herein may be a mobile phone, a tablet computer, a vehicle-mounted monitoring system, or the like.

To describe the technical solutions in embodiments of this disclosure more clearly, the following further describes in detail the camera module provided in this disclosure with reference to the accompanying drawings. It should be understood that terms such as "first" and "second" in the following are merely used for distinguishing and description, and cannot be understood as an indication or implication of relative importance or an indication or implication of an order.

An embodiment of this disclosure provides a camera module <NUM>. As shown in <FIG>, the camera module <NUM> includes a camera motor <NUM>, a lens <NUM>, a variable aperture <NUM>, and an image sensor assembly <NUM>. The camera motor <NUM> is equivalent to a power source of the camera module <NUM>, and is configured to drive the lens <NUM> and the variable aperture <NUM> to move when a camera is in operation, to meet an imaging requirement. <FIG> further shows a light incoming hole J formed by the variable aperture <NUM>. When the camera is in operation, external light enters the lens <NUM> through the light incoming hole J of the variable aperture <NUM>, passes through the lens <NUM>, and is projected onto the image sensor assembly <NUM> for imaging. The lens <NUM> is installed in the camera motor <NUM> in the manner shown in <FIG>, so that light passing through the lens <NUM> can reach the image sensor assembly <NUM> at an end that is of the camera motor <NUM> and that is away from the variable aperture <NUM> for imaging. The variable aperture <NUM> may be fastened to the camera motor <NUM> by using a support part A protruding from the camera motor <NUM>, so that both of the variable aperture <NUM> and the lens <NUM> may be driven by the camera motor <NUM>. The image sensor assembly <NUM> herein includes an image sensor, another external connection assembly, and a support structure.

Specifically, in the structure of the camera motor <NUM> shown in <FIG>, the camera motor <NUM> includes a focusing part <NUM>, a top cover <NUM>, and an image stabilization part <NUM>. The top cover <NUM> and the image stabilization part <NUM> cooperate up and down to form accommodation space used to accommodate the focusing part <NUM>, and the focusing part <NUM> is specifically fastened to the image stabilization part <NUM>. The lens <NUM> and the variable aperture <NUM> are fastened on the focusing part <NUM>. The focusing part <NUM> may drive the lens <NUM> and the variable aperture <NUM> to move in an optical axis direction (that is, a direction Z shown in <FIG>), to implement focusing. The image stabilization part <NUM> may drive the focusing part <NUM> to move on a surface perpendicular to the optical axis direction, to implement an image stabilization effect of the lens <NUM>. Certainly, the support part A configured to support and fasten the variable aperture <NUM> is disposed on the focusing part <NUM>, and extends out of the camera motor <NUM>. On the top cover <NUM>, a first optical hole <NUM> for light to pass through is formed, and an axis of the first optical hole <NUM> is collinear with an optical axis.

For a structure of the focusing part <NUM>, refer to <FIG> shows a three-dimensional structure of the focusing part <NUM>. The focusing part <NUM> specifically includes a housing <NUM>, a base <NUM>, a carrier <NUM>, and a driver <NUM>. The housing <NUM> cooperates with the base <NUM> to form accommodation space for accommodating the carrier <NUM> and the driver <NUM>. Because the housing <NUM> blocks the driver <NUM>, a structure of the driver <NUM> is not shown in <FIG>.

With reference to the structures in <FIG> and <FIG>, refer to a schematic diagram of a cross-sectional structure of the camera motor <NUM> shown in <FIG>. The driver <NUM> in the focusing part <NUM> is implemented in a form of a drive coil <NUM> and a drive magnet <NUM>. The drive coil <NUM> is disposed on the carrier <NUM>, and the drive magnet <NUM> may be fastened on the base <NUM>. When the camera motor <NUM> is in operation, the base <NUM> is equivalent to a fixing part, the carrier <NUM> is equivalent to a movable part, and the driver <NUM> is configured to drive the carrier <NUM> to move relative to the base <NUM> in an optical axis direction. In this way, the drive coil <NUM> is opposite to the drive magnet <NUM>. When the drive coil <NUM> is powered on, the drive coil <NUM> generates an electric field, and the drive magnet <NUM> located in the electric field may be driven to move. Movement of the drive magnet <NUM> may be adjusted by changing a magnitude and a direction of a current in the drive coil <NUM>. Certainly, the driver <NUM> may alternatively be implemented in another form. This is not limited herein. In addition, in this implementation, the drive coil <NUM> is disposed on the carrier <NUM> and is equivalent to a movable end of the driver <NUM>, and the drive magnet <NUM> is fastened on the base <NUM> and is equivalent to a fixed end of the driver <NUM>, to implement relative drive motion. Therefore, the drive magnet <NUM> may alternatively be disposed on another structure that is fastened relative to the base <NUM>. For example, the drive magnet <NUM> may alternatively be fastened on the top cover <NUM>, and an effect of driving the drive coil <NUM> by the drive magnet <NUM> can still be achieved.

Both of the variable aperture <NUM> and the lens <NUM> in the camera module <NUM> are disposed on the carrier <NUM> of the focusing part <NUM>, the variable aperture <NUM> and the lens <NUM> can simultaneously move in the optical axis direction to implement accurate focusing, and the variable aperture <NUM> is independent of the lens <NUM>. This is equivalent to reducing assembly difficulty of the camera module <NUM>, and facilitates miniaturization of the camera module <NUM>. In this way, the camera module <NUM> can be applied to a small electronic device such as a mobile phone. In addition, adjustment of the variable aperture <NUM> on the light incoming hole may not be affected by movement of the lens <NUM>, and a higher-quality image shooting requirement is met. For a structure of the housing <NUM>, refer to <FIG>. A second optical hole <NUM> for light to pass through is formed on the housing <NUM>. A specific shape of the second optical hole <NUM> is not limited herein, and a shape in <FIG> is merely an example. For a structure of the base <NUM>, refer to <FIG>. A third optical hole <NUM> for light to pass through is formed on the base <NUM>. It may be understood that when the camera motor <NUM> and the lens <NUM> are assembled, axes of both of the second optical hole <NUM> and the third optical hole <NUM> are collinear with an optical axis of the lens <NUM>.

For a structure of the carrier <NUM>, refer to <FIG>. An installation hole <NUM> is formed on the carrier <NUM>. When the installation hole <NUM> is assembled and cooperates with the lens <NUM>, the lens <NUM> is fastened in the installation hole <NUM>. Certainly, an axis of the installation hole <NUM> is collinear with the optical axis of the lens <NUM>, to ensure an imaging effect. The support part A for fastening the variable aperture <NUM> is formed on the carrier <NUM>.

In the structure of the driver <NUM> shown in <FIG>, the drive coil <NUM> is disposed on the carrier <NUM>. In a possible implementation, with reference to the structure of the carrier <NUM> shown in <FIG>, an installation groove M is formed on a periphery of the carrier <NUM>, and the drive coil <NUM> is disposed in the installation groove M, to obtain a structure shown in <FIG>.

To control the driver <NUM>, the focusing part <NUM> further includes a control assembly <NUM>. Specifically, as shown in <FIG>, the control assembly <NUM> may be disposed on the base <NUM>. The control assembly <NUM> herein may control the driver <NUM>, and may further exchange information with an external main control structure. In the structure shown in <FIG>, the control assembly <NUM> is disposed on the base <NUM> in a manner in which one end of the control assembly <NUM> is fastened on the base <NUM>. The control assembly <NUM> may alternatively be integrated on the base <NUM> in a form of attachment, or may be disposed on the base <NUM> in another structure form. This is not limited herein. Certainly, the control assembly <NUM> is a part of the camera module <NUM> in this embodiment. Certainly, the control assembly <NUM> may alternatively be disposed in another structure, which does not affect function implementation of the control assembly <NUM>.

It should be noted that in the camera module <NUM> provided in this disclosure, the variable aperture <NUM> is not only relatively independent of the lens <NUM> in structure, but also may work independently of the lens <NUM>. The structure shown in <FIG> may be used as a reference for the variable aperture <NUM>. The variable aperture <NUM> includes a housing <NUM>, a drive structure <NUM> disposed in the housing <NUM>, and a plurality of blades <NUM>. The plurality of blades <NUM> are disposed annularly to form the light incoming hole J. Certainly, an axis of the light incoming hole J herein is collinear with an axis of the lens <NUM>. The plurality of blades <NUM> may rotate under driving of the drive structure <NUM>, to change a size of the light incoming hole J and change an amount of light passing through the light incoming hole J. When the variable aperture <NUM> is used independently, as long as a power supply is applied to the drive structure <NUM>, the drive structure <NUM> may be started, to drive the blades <NUM> to rotate to change the size of the light incoming hole J.

In a possible implementation, operation of the variable aperture <NUM> may be further controlled by the control assembly <NUM>. To control the variable aperture <NUM> by the control assembly <NUM>, a structure that can transmit electrical signals needs to be formed between the control assembly <NUM> and the drive structure <NUM> of the variable aperture <NUM>.

In a possible implementation, as shown in <FIG>, a first spring <NUM> is disposed on a side that is of the carrier <NUM> and that faces the variable aperture <NUM>, and the first spring <NUM> is electrically connected to the control assembly <NUM> fastened on the base <NUM> (as shown in <FIG>). Specifically, the first spring <NUM> is made of a metal material, which may be specifically copper, copper alloy, or another metal with good conductivity. Certainly, the first spring <NUM> serves as a carrier for transmitting electrical signals between the variable aperture <NUM> and the control assembly <NUM>. Therefore, a structure in which the control assembly <NUM>, the first spring <NUM>, and the drive structure <NUM> of the variable aperture <NUM> are connected may be shown in <FIG>.

In another possible implementation, similar to the structure shown in <FIG>, a difference lies in that the first spring <NUM> is not directly in contact with the drive structure <NUM> of the variable aperture <NUM> to implement electrical connection. Instead, as shown in <FIG>, a connection circuit <NUM> electrically connected to the drive structure <NUM> of the variable aperture <NUM> may be formed on the support part A of the carrier <NUM>, and the connection circuit <NUM> is electrically connected to the first spring <NUM>. In this way, electrical signal transmission between the drive structure <NUM> of the variable aperture <NUM> and the control assembly <NUM> is implemented by using the connection circuit <NUM> and the first spring <NUM>. Herein, the connection circuit <NUM> formed on the carrier <NUM> may be formed by directly cabling on the carrier <NUM>, or the connection circuit <NUM> may be formed by integrating a flexible circuit into the carrier <NUM>.

In the foregoing two implementations, the first spring <NUM> serves as a carrier for transmitting at least a part of electrical signals between the control assembly <NUM> and the drive structure <NUM> of the variable aperture <NUM>. To enhance an electrical signal transfer effect, the first spring <NUM> may be divided into a plurality of sub-springs <NUM> disposed on a same layer based on a specific structure of the first spring <NUM>. In a structure of the first spring <NUM> shown in <FIG>, the plurality of sub-springs <NUM> may be distributed annularly around an optical axis by using the optical axis as a center.

In addition, in the foregoing two implementations, because the first spring <NUM> serves as a carrier for transmitting at least a part of electrical signals, the first spring <NUM> belongs to an electrical connection structure. It should be considered that another electrical device (for example, the drive coil <NUM> and the drive magnet <NUM> included in the driver <NUM>) may be further disposed on the camera module <NUM> provided in this embodiment. To prevent mutual interference between the first spring <NUM> and this type of electrical device, an insulation isolation structure may be sandwiched between the first spring <NUM> and this type of electrical device. For example, as shown in <FIG>, a spacer <NUM> may be sandwiched between the first spring <NUM> and the drive magnet <NUM>. Based on the structure shown in <FIG>, the drive coil <NUM> is disposed in the groove of the carrier <NUM>, and the carrier <NUM> serves as an insulation isolation structure between the first spring <NUM> and the drive coil <NUM>. Certainly, a structure of the spacer <NUM> is not limited, and may be a flat plate or a baffle plate. In addition, a location at which the spacer <NUM> is disposed relative to the first spring <NUM> may also be determined based on relative locations of other electrical devices. This is not limited herein.

It should be noted that, in addition to being used as an electrical signal carrier, the first spring <NUM> may alternatively be used as a connector between the carrier <NUM> and the fixing part (for example, the base <NUM> or the housing <NUM>) of the camera module <NUM>. Herein, the first spring <NUM> may be connected between the carrier <NUM> and the housing <NUM>. Corresponding to the first spring <NUM>, as shown in <FIG>, a second spring <NUM> may be further disposed on a side that is of the carrier <NUM> and that faces the image sensor assembly <NUM>, and the second spring <NUM> may be connected to the carrier <NUM> and the base <NUM>. Because the first spring <NUM> and the second spring <NUM> are respectively located on two sides (upper and lower sides shown in <FIG>) of the carrier <NUM>, the first spring <NUM> and the second spring <NUM> exert action forces in opposite directions on the carrier <NUM> from two opposite directions, so that the carrier <NUM> is in a relatively stable state. Certainly, due to elastic characteristics of the first spring <NUM> and the second spring <NUM>, the carrier <NUM> may still be driven by the driver <NUM> to move relative to the base <NUM>.

Based on the foregoing description of the structure of the camera module <NUM> provided in this disclosure, refer to an exploded view of a structure of the camera module <NUM> shown in <FIG>. As shown in <FIG>, in the camera module <NUM>, the driver <NUM> is implemented by using the drive coil <NUM> in cooperation with the drive magnet <NUM>, the drive coil <NUM> surrounds a periphery of the carrier <NUM>, and the drive magnet <NUM> is implemented by using two symmetric strip magnets to cooperate with the drive coil <NUM>. The first spring <NUM> is separated from the drive magnet <NUM> by using two long-strip-shaped spacers <NUM>. A rectangular spacing frame <NUM> may be further sandwiched between the housing <NUM> and the first spring <NUM> to prevent the first spring <NUM> from contacting the housing <NUM>. Certainly, the spacing frame <NUM> may alternatively be implemented in another shape. This is not limited herein. Other structures are described above, and details are not described herein again. Certainly, <FIG> provides a structure of the camera module <NUM> by using only an example. This does not limit the structure of the camera module <NUM> that needs to be protected in this disclosure.
