Camera module and electronic device

[0001] The present application claims priority to the Chinese patent application No. 202410428090.8, filed on April 9, 2024, and entitled "Camera module and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of camera technology, and in particular, to a camera module and an electronic device. BACKGROUND

[0003] As one of the important components of an electronic device, a camera module can realize the photographing function of the electronic device. In order to realize the focusing or optical image stabilization of the camera module, the lens assembly in the camera module needs to move, which requires the electronic device to design sufficient space for the movement of the lens assembly in the thickness direction of the electronic device. This will result in a larger thickness of the electronic device, which cannot meet the light and thin requirements of the electronic device. SUMMARY

[0004] The embodiments of the present application provide a camera module and an electronic device, which can make the lens assembly in the camera module have sufficient movement space without increasing the thickness of the electronic device.

[0005] In a first aspect, the embodiments of the present application provide a camera module, which is used for being installed in an electronic device; the camera module comprises a module cover plate, a cover plate support, a camera device and a driving device; the module cover plate is connected with the cover plate support, the module cover plate is arranged at the light entering side of the camera device, the module cover plate is used for allowing external light to pass through and enter the camera device, and the module cover plate is used for being accommodated in the opening of the electronic device; the camera device has an optical axis, and the extension direction of the optical axis is an optical axis direction; the driving device comprises a first matching part, and the cover plate support comprises a second matching part; one of the first matching part and the second matching part is a pin, and the other is a groove; the groove extends along the direction around the optical axis; the distance from the opposite ends of the extension direction of the groove to the module cover plate is different; the pin is inserted into the groove and is in sliding connection with the groove; and the driving device is used for rotating the first matching part around the optical axis, moving the pin relative to the groove, and driving the cover plate support to move the module cover plate along the optical axis direction.

[0006] In the embodiments of the present application, when the driving device drives the cover bracket and the module cover to rise, the distance between the module cover and the camera device increases, which provides more space for the movement of the lens assembly, so that the camera module can have space to realize large-stroke auto focus (AF) movement, which is beneficial to realize multi-focus shooting, improve focusing speed, and improve focusing performance in dark light environment. In addition, the camera module can also have space for optical image stabilization (OIS) movement, which is convenient for improving imaging quality through OIS movement. When the driving device drives the cover bracket and the module cover to descend to the initial position, the electronic device restores the initial appearance and does not affect the thickness experience of the electronic device. Therefore, the scheme of the embodiments of the present application can utilize the external space of the electronic device to meet the stroke needs of the lens assembly, without increasing the thickness of the electronic device, so that the imaging quality and thinness can be considered.

[0007] In an implementation form of the first aspect, the distance between the groove and the module cover in the optical axis direction gradually increases from one end of the groove close to the module cover to the other end of the groove away from the module cover. The groove in this implementation form is inclined to the module cover as a whole, so that the pin can exert a force along the optical axis direction to the inner wall of the groove, which can drive the module cover to move along the optical axis direction.

[0008] In an implementation form of the first aspect, the groove comprises a parallel sub-groove and an inclined sub-groove, the parallel sub-groove is connected to the inclined sub-groove, the extension direction of the parallel sub-groove is parallel to the module cover, and the extension direction of the inclined sub-groove is not parallel to the module cover. In this implementation form, when the pin is located in the parallel sub-groove, the module cover does not move along the optical axis. By designing the parallel sub-groove in the groove, when the pin is located in the parallel sub-groove, the module cover can maintain the current height, thereby realizing reliable hovering of the module cover when the camera module is powered off, and also realizing energy saving.

[0009] In an implementation form of the first aspect, the groove comprises a parallel sub-groove and an inclined sub-groove, the inclined sub-groove comprises a first inclined sub-groove and a second inclined sub-groove, the parallel sub-groove is connected between the first inclined sub-groove and the second inclined sub-groove, and the first inclined sub-groove and the second inclined sub-groove are respectively located on opposite sides of the parallel sub-groove in a width direction of the parallel sub-groove; an extension direction of the parallel sub-groove is parallel to the module cover plate, and an extension direction of the first inclined sub-groove and an extension direction of the second inclined sub-groove are both not parallel to the module cover plate; in a process in which the pin is located in the first inclined sub-groove and moves relative to the groove, the module cover plate extends out of the opening, and the camera device is located at the initial position; when the pin is located in the parallel sub-groove, the module cover plate stops moving in the optical axis direction, and the camera device remains at the initial position; in a process in which the pin is located in the second inclined sub-groove and moves relative to the groove, the module cover plate continues to move in the optical axis direction and away from the camera device, and the camera device is configured to move in the optical axis direction to the first position, the first position being closer to the module cover plate than the initial position.

[0010] In the implementation form, the parallel sub-groove is arranged between the two inclined sub-grooves, the camera device is not lifted when the pin is in the first inclined sub-groove and the parallel sub-groove, and the camera device can be lifted when the pin moves relative to the groove in the second inclined sub-groove, so that the camera device is lifted only when needed, movement space is provided for OIS movement of the camera device to realize OIS, or AF requirements of the camera device in some scenes can be realized, and power consumption caused by lifting of the camera device can be reduced.

[0011] In an implementation form of the first aspect, the camera device comprises a gimbal and a camera body, the gimbal is connected to the camera body, and the gimbal is configured to drive the camera body to rotate and make the optical axis swing to realize optical image stabilization; the module cover plate, the cover plate support and the gimbal are arranged in sequence in the optical axis direction.

[0012] In the implementation form, when the gimbal drives the camera body to make OIS movement, the optical axis deviates from the initial position in a swinging manner, and the optical axis is inclined relative to the initial position after swinging. For example, when the optical axis is in the vertical direction, the optical axis deviates to the left or to the right relative to the vertical direction after swinging. The swinging can be in any direction, for example, the gimbal can drive the camera body to rotate around any rotation axis intersecting the optical axis. The triggering and duration of the swinging can be set as needed. By arranging the gimbal in the camera device, a large-angle anti-shake can be realized, and the imaging quality of the camera module can be improved in dark light environment, long exposure, motion and other scenes.

[0013] In an implementation form of the first aspect, when the pin moves in the first inclined sub-groove relative to the groove, the module cover plate is configured to move along the optical axis and extend out of the opening, and the gimbal is located at the initial position; when the pin moves in the parallel sub-groove relative to the groove, the module cover plate is not configured to move along the optical axis, and the gimbal is located at the initial position; when the pin moves in the second inclined sub-groove relative to the groove, the module cover plate is configured to move along the optical axis and continue to extend out of the opening, and the gimbal is configured to drive the camera main body to move along the optical axis and approach the module cover plate. By arranging the parallel sub-groove between the two inclined sub-grooves, the gimbal can be lifted only when the pin moves in the second inclined sub-groove relative to the groove, thereby realizing OIS movement. Before that, the gimbal cannot be lifted and thus cannot perform OIS movement. In this way, the gimbal can perform OIS only when needed. Since the gimbal works more power-consuming, the implementation form is beneficial to reduce the power consumption of the gimbal.

[0014] In an implementation form of the first aspect, the first matching part is a pin, the second matching part is a groove, and the driving device is configured to drive the pin to move relative to the groove from one end of the groove close to the module cover plate to the other end of the groove away from the module cover plate. Arranging the pin in the driving device and the groove in the cover plate support can meet the structural layout requirements of the camera module and ensure the reliability and producibility of the camera module.

[0015] In an implementation form of the first aspect, the cover plate support surrounds the optical axis, and the module cover plate and the cover plate support are arranged along the optical axis. The structure of the cover plate support and the position design of the module cover plate and the cover plate support in the implementation form can meet the structural layout requirements of the camera module and ensure the reliability and producibility of the camera module.

[0016] In an implementation form of the first aspect, the driving device further comprises a driving member, the driving member surrounds the outer periphery of the cover plate support, the pin is connected to the driving member, the driving device is configured to drive the driving member to rotate around the optical axis, and the driving member is configured to drive the pin to rotate around the optical axis and move relative to the groove. The driving member can serve as a bearing structure of the pin and can also receive a driving force, thereby realizing the movement cooperation between the pin and the groove.

[0017] In an implementation form of the first aspect, the driving member comprises a body, a first guide column and a first elastic member, the body surrounds the outer periphery of the cover plate support, and the first guide column is fixed to the body; the pin comprises a connecting part and a driving part, the connecting part is connected to the driving part, the connecting part is provided with a connecting part through hole, the first guide column penetrates through the connecting part through hole and is in sliding connection with the connecting part, the opposite ends of the first elastic member are respectively abutted against the connecting part and the body, and the driving part is located in the groove and is in sliding connection with the groove. By designing the structure of the driving member and the pin, the elastic movable connection between the pin and the driving member can be realized. The elastic movable connection can buffer the impact from the outside, so that the cooperation between the pin and the groove has a certain impact resistance.

[0018] In an implementation form of the first aspect, the driving member further comprises a transmission portion connected to the body, the transmission portion extends along the circumference of the body, and a plurality of first engagement teeth are arranged at an end of the transmission portion away from the body; the driving device further comprises a transmission mechanism, the transmission mechanism has a plurality of second engagement teeth, the second engagement teeth are engaged with the first engagement teeth, and the transmission mechanism is configured to transmit movement to the transmission portion to rotate the driving member around the optical axis. By designing the structure of the driving member, the driving member is engaged to participate in transmission, so that the driving member can reliably transmit movement to the pin, and the structural layout requirements of the camera module can be met, thereby ensuring the reliability and mass production of the camera module.

[0019] In an implementation form of the first aspect, the camera module further comprises a limiting structure connected to the cover support, the limiting structure is configured to abut against and limit the camera device to keep the camera device at the initial position. When the pin moves relative to the second inclined sub-groove, the limiting structure no longer limits the camera device. By providing the limiting structure and configuring the limiting structure to limit the camera device when the camera device is at the initial position, the camera device cannot be lifted and thus cannot move to reduce the power consumption of the camera device. The limiting structure can reliably limit the camera device in a mechanical manner.

[0020] In an implementation form of the first aspect, the limiting structure comprises a second elastic member and a limiting member, opposite ends of the second elastic member are respectively abutted against the cover support and the limiting member, and an end of the limiting member away from the second elastic member is configured to abut against and limit the camera device. The limiting structure of this implementation form is simple and reliable, and can meet the needs of products.

[0021] In an implementation form of the first aspect, the limiting member comprises a limiting plate and a limiting column connected to each other, the limiting column extends along the thickness direction of the limiting plate, opposite ends of the second elastic member are respectively abutted against the cover support and the limiting plate, and an end of the limiting column away from the second elastic member is configured to abut against and limit the camera device. The limiting structure of this implementation form is simple and reliable, and can meet the needs of products.

[0022] In an implementation form of the first aspect, the limiting structure further comprises a frame, the frame is fixedly connected to the cover support and surrounds a receiving space, and the frame is provided with a frame through hole; the second elastic member and the limiting plate are located in the receiving space, and the limiting column passes through the frame through hole and is in sliding connection with the frame. The limiting structure of this implementation form is simple and reliable, and can meet the needs of products.

[0023] In an implementation form of the first aspect, the camera module further comprises a base fixedly arranged in the camera module, and a third elastic member, opposite ends of the third elastic member abutting against the base and the camera device respectively, the camera device, the third elastic member and the base being arranged in sequence along the optical axis direction; the third elastic member is configured to be in a compressed state when the holder is in the initial position, and to be elongated and push the camera device to move along the optical axis direction to the first position when the pin moves relative to the second inclined sub-groove in the second inclined sub-groove.

[0024] In an implementation form of the first aspect, the holder is provided with a camera device through hole; the camera module further comprises a stopper and a second guide column, the second guide column connecting the stopper and the base, the second guide column passing through the camera device through hole and being in sliding connection with the camera device, the stopper, the camera device and the base being arranged in sequence along the optical axis direction. By arranging the second guide column and the stopper, the lifting movement of the camera device can be guided, and the lifting height of the camera device can also be limited, so that the camera device maintains the current height after being lifted to the set height.

[0025] In an implementation form of the first aspect, the camera device comprises a holder and a camera main body, the holder and the camera main body being movably connected, the holder being configured to drive the camera main body to rotate and make the optical axis swing to realize optical image stabilization; the module cover plate, the cover plate support and the holder are arranged in sequence along the optical axis direction; the holder comprises a first carrier, a second carrier, a first driving mechanism and a second driving mechanism; the first carrier surrounds the outer periphery of the camera main body, the first carrier and the camera main body being rotationally connected, the first driving mechanism being configured to drive the camera main body to rotate relative to the first carrier about a first rotation axis; the second carrier surrounds the outer periphery of the first carrier, the second carrier and the first carrier being rotationally connected, the second driving mechanism being configured to drive the first carrier to drive the camera main body to rotate relative to the second carrier about a second rotation axis; wherein the extension direction of the first rotation axis, the extension direction of the second rotation axis and the optical axis direction of the camera module intersect with each other.

[0026] In the present implementation, by arranging the first carrier around the camera main body and the second carrier around the first carrier, the camera main body, the first carrier and the second carrier are arranged in a nested manner. The first carrier of the present embodiment has the function of "one thing with multiple uses". On the one hand, the first carrier can cooperate with the second carrier to serve as the stator of the camera main body rotating around the first rotation axis. On the other hand, the first carrier can serve as the rotor of the camera main body rotating around the second rotation axis. In this way, the first carrier can play the role of structural reuse, thereby simplifying the structure of the gimbal module and achieving the miniaturization of the gimbal module. The second carrier of the present embodiment also has the function of "one thing with multiple uses". The second carrier can cooperate with the first carrier to serve as the stator of the camera main body rotating around the first rotation axis, and the second carrier can also serve as the stator of the camera main body rotating around the second rotation axis. In this way, the second carrier can serve as the stator of the components of the camera module. In addition, the second carrier can be arranged around the first carrier, and the second carrier has the function of protecting the first carrier, the first driving mechanism and the second driving mechanism of the gimbal module. In this way, the second carrier can play the role of structural reuse, thereby simplifying the structure of the gimbal module and facilitating the miniaturization of the gimbal module.

[0027] In the present implementation, the second carrier can serve as the stator of the camera module and also protect the first carrier, the first driving mechanism and the second driving mechanism of the gimbal. When the camera module is applied to an electronic device, the second carrier of the gimbal can be directly fixed to the structural member (such as the shell or the middle frame) of the electronic device. Compared with the traditional camera module solution (the outer part of the gimbal of the camera module needs to be provided with a shell, and the camera module is packaged and fixed to the structural member (such as the shell or the middle frame) of the electronic device through the shell), in the present implementation, since the second carrier of the gimbal can be directly fixed to the structural member (such as the shell or the middle frame) of the electronic device, the camera module can no longer need to be additionally provided with a shell, which is conducive to simplifying the structure of the camera module and further facilitating the miniaturization of the camera module. In addition, the step of packaging and fixing the camera module to the structural member (such as the shell or the middle frame) of the electronic device through the shell can be omitted, thereby reducing the cost.

In this implementation form, the first coil can be used as an AF coil to jointly act with the magnet to drive the first support and the lens to perform AF movement. The second coil can be used as an OIS coil to jointly act with the magnet to drive the second support, the first support and the lens to perform OIS movement. By sharing the magnet for the first coil and the second coil, the amount of the magnet can be reduced, which is conducive to reducing the weight of the camera module, increasing the structural compactness of the camera module and reducing the volume of the camera module.

[0029] In an implementation form of the first aspect, the first coil and the magnet are both located between the first support and the second support, the first coil is fixedly connected with the first support, and the magnet is fixedly connected with the second support; the second coil is fixedly arranged and located on a side of the second support away from the magnet. The layout and connection mode of each component in this implementation form can meet the product needs.

[0030] In a second aspect, the embodiments of the present application provide an electronic device comprising the camera module of any one of the above, the electronic device being provided with an opening hole communicating an inner space and an outer space of the electronic device, and the module cover plate of the camera module is configured to be accommodated in the opening hole. In the embodiments of the present application, the opening hole of the electronic device can be arranged at any position, for example, on the rear shell or on the display screen. When the driving device drives the module cover plate to rise, the module cover plate can rise from the opening hole and protrude from the outer surface of the electronic device. The scheme of the embodiments of the present application can utilize the external space of the electronic device to meet the stroke requirement of the lens assembly, without increasing the thickness of the electronic device, and the imaging quality and thinness can be considered.

[0031] In an implementation form of the second aspect, the electronic device further comprises a display screen and a shell, the display screen and the camera module are both mounted on the shell, a display surface of the display screen is arranged away from a light entering side of the camera module, and the opening hole is arranged on the shell. The camera module in this implementation form can be a rear camera module, and this implementation form can realize the lifting of the module cover plate of the rear camera module relative to the outer surface of the electronic device.

[0032] In an implementation form of the second aspect, the shell comprises a shell body and a device cover plate, the device cover plate covers the shell body, and the opening is located in a region where the device cover plate is located.

[0066] For the convenience of understanding, the relevant technical terms involved in the embodiments of the present application are explained and described below.

[0067] The side on which the lens is located is the light-entering side (or object side), and the surface of the lens close to the light-entering side is called the light-entering surface (or object side surface);

[0068] Image side, the side on which the image of the object to be photographed is located, the surface of the lens close to the image side is called the image side surface;

[0069] Aperture value, a relative value (reciprocal of relative aperture) derived from the focal length of the lens / diameter of the lens entrance pupil. The smaller the aperture value, the larger the aperture, and the more light will enter in the same unit of time. The larger the aperture value, the smaller the aperture, the smaller the depth of field, and the background content of the photograph will be blurred, similar to the effect of a long focal length lens;

[0070] Optical axis, an axis that passes vertically through the center of the lens. The optical axis of the lens is the axis that passes through the centers of all the lenses in the lens. When light rays parallel to the optical axis enter a convex lens, the ideal convex lens should be such that all the light rays converge at a point behind the lens. This point at which all the light rays converge is called the focal point.

[0071] Optical axis direction: the direction of the extension of the optical axis.

[0083] As shown in FIG. 1 and FIG. 2, the module cover plate 103 can be accommodated in the opening 200a, i.e. along the axis direction of the opening 200a, the projection of the module cover plate 103 is located in the projection of the opening 200a, wherein the projection of the opening 200a is a closed curve, such as a circle. The module cover plate 103 is exposed, and a user can see the module cover plate 103 from the outside of the electronic device 1000. Illustratively, the camera module 100 can be a rear camera module, and the module cover plate 103 can be accommodated in the opening 200a on the rear shell 202, and the light entrance side of the camera module 100 is arranged opposite to the display surface 300a of the display screen 300, wherein the display surface 300a is the surface of the display screen 300 for displaying images. If the camera module 100 is a front camera module, the module cover plate 103 is accommodated in the opening 200a on the display screen 300. It can be understood that the electronic device 1000 can also include camera modules 100 that are both rear camera modules and front camera modules.

[0084] Hereinafter, the camera module 100 is taken as a rear camera module, and the module cover plate 103 is accommodated in the opening 200a on the rear shell 202 as an example, and the description will be continued.

[0085] As shown in FIG. 1 and FIG. 2, the cover plate support 102 can be located in the electronic device 1000, for example, mounted in the internal space. The cover plate support 102 can have a part exposed or completely not exposed. The cover plate support 102 is used to connect and carry the module cover plate 103.

[0086] As shown in FIG. 1 and FIG. 2, other parts such as the camera device and the driving device can be located in the electronic device 1000, for example, accommodated in the internal space. Since the other parts such as the camera device and the driving device are hidden inside, the dashed line is used to show the approximate outline in FIG. 1.

[0087] The camera device is used to collect and process light, and convert the light signal into an electrical signal. The camera device can include a lens assembly and an image sensor, etc. The camera device can realize automatic focusing, or can realize automatic focusing and optical image stabilization.

[0088] The driving device can drive the cover plate support 102 to move along the optical axis direction, so that the cover plate support 102 drives the module cover plate 103 to move along the optical axis direction, that is, to move along the Z axis shown in FIG. 2. The movement is bidirectional, that is, the cover plate support 102 drives the module cover plate 103 to move along the positive direction of the Z axis (this movement can be referred to as rising), and can also move along the negative direction of the Z axis (this movement can be referred to as falling). The module cover plate 103 can have an initial position, at which the module cover plate 103 is, for example, substantially flush with the outer surface of the rear shell 202. As shown in FIG. 2, from the initial position, the module cover plate 103 can protrude from the opening 200a and be higher than the outer surface of the rear shell 202 by a certain distance, at which time the module cover plate 103 is exposed to the outer surface of the electronic device 1000. The module cover plate 103 can also fall and return to the initial position. The driving principle of the driving device to the cover plate support 102 and the module cover plate 103 will be described below.

[0089] Referring to FIG. 2, when the driving device drives the cover plate support 102 and the module cover plate 103 to rise, the distance between the module cover plate 103 and the camera increases, which provides more space for the movement of the lens assembly, so that the camera module 100 can have space to realize large-stroke auto focus (AF) movement, which is beneficial to realize multi-focus shooting, improve focusing speed, and improve focusing performance in dark light environment. In addition, the camera module 100 can also have space for optical image stabilization (OIS) movement, which is convenient for improving imaging quality through OIS movement.

[0090] Referring to FIG. 2, when the driving device drives the cover plate support 102 and the module cover plate 103 to fall to the initial position, the electronic device 1000 returns to the initial appearance and does not affect the thickness experience of the electronic device 1000.

[0091] Therefore, the scheme of the embodiment of the present application can utilize the external space of the electronic device 1000 to meet the stroke requirement of the lens assembly, without increasing the thickness of the electronic device 1000, so that the imaging quality and thinness can be considered.

[0092] As shown in FIGS. 1 and 2, in an embodiment, the camera module 100 can further include a first decorative piece 101, which can be, for example, substantially annular, a part of which can be located in the opening 200a and another part of which can be exposed. The first decorative piece 101 can surround the outer periphery of the module cover plate 103. Illustratively, the first decorative piece 101 can also surround the outer periphery of the cover plate support 102. The first decorative piece 101 has a decorative effect and can also have a protective effect on the module cover plate 103 and the like. It can be understood that the first decorative piece 101 can also not be provided.

[0093] Based on the above-described embodiments, FIG. 3 shows a top view structural schematic diagram of an electronic device 1000 according to another embodiment of the present application. As shown in FIG. 3, the electronic device 1000 can include a plurality of camera modules, at least one of which is the camera module 100 described above. The device housing 200 can further include a device cover plate 204, which can be disposed on the rear shell 202, for example, and which is exposed to the outside and can be seen by a user from the outside of the electronic device 1000. In this embodiment, the rear shell 202 and the middle frame 203 can be collectively referred to as a shell body, and the device cover plate 204 covers the shell body. The opening 200a can pass through the device cover plate 204 and the rear shell 202 to communicate the inside and outside of the electronic device 1000. It can also be considered that the opening 200a is located in the area where the device cover plate 204 is located.

[0094] As shown in FIG. 3, the device cover plate 204 can have a plurality of light-transmitting regions 204a, each of which can correspond to a camera module arranged thereunder, and each of which can allow external light to pass through so that the external light can be collected by the corresponding camera module to form an image. The device cover plate 204 can visually group the plurality of camera modules together and can also serve the purposes of protection and decoration, etc.

[0095] FIG. 3 shows that one of the plurality of camera modules is the camera module 100 described above, and the module cover plate 103 of the camera module 100 can be raised and lowered relative to the device cover plate 204. It can be understood that this is merely an example, and in practice, there can be more camera modules 100 in the plurality of camera modules as needed.

[0096] Based on the above-described embodiments, in one embodiment, a plurality of camera modules can be provided in the electronic device 1000, such that a portion of the camera modules are located in the area where the device cover plate 204 is located, and another portion of the camera modules are not located in the area where the device cover plate 204 is located but are arranged side by side with the device cover plate 204. The other portion of the camera modules does not need to collect external light through the device cover plate 204, but collects external light through the module cover plate of the camera module itself. Among them, at least one of the portion of the camera modules located in the area where the device cover plate 204 is located can be the camera module 100 described above, and / or at least one of the portion of the camera modules not located in the area where the device cover plate 204 is located can be the camera module 100 described above.

[0097] The above outlines the principle structure of the camera module 100, and the specific structure of the camera module 100 will be described in detail below.

As shown in Fig. 4 and Fig. 5, the camera module 100 can include a module housing 100a and a moving part 100b. Illustratively, the camera module 100 can further include a first decorative piece 101. The first decorative piece 101 can be fixedly connected with the module housing 100a, and the first decorative piece 101 and the module housing 100a can be arranged along the optical axis direction, for example. The first decorative piece 101 and the module housing 100a can enclose a cavity with an opening, and at least a part of the moving part 100b can be accommodated in the cavity.

[0099] In the embodiment, the module housing 100a and the first decorative piece 101 are both fixed parts in the camera module 100, which can be referred to as fixed parts or stators. The structure of the fixed parts can be flexibly designed as needed, and the embodiment is not limited in this regard. The moving part 100b is a part that can move in the camera module 100, which can also be referred to as a rotor. At least a part of the moving part 100b can be accommodated in the fixed part.

[0100] The structure of the moving part 100b will be described in detail below.

As shown in Fig. 5 and Fig. 6, the moving part 100b can include a cover plate support 102, a module cover plate 103, a driving device 100c, and a camera device 111, etc. In an embodiment, the moving part 100b can further include a second decorative piece 112 and an elastic shielding piece 104. The cover plate support 102, the module cover plate 103, the camera device 111, the second decorative piece 112, and the elastic shielding piece 104, etc. can be located in the fixed part, and at least a part of the driving device 100c can be located in the fixed part.

[0102] Fig. 7 shows a B-B assembled sectional view of the module cover plate 103, the second decorative piece 112, and the elastic shielding piece 104 in Fig. 6.

[0103] As shown in Fig. 6 and Fig. 7, the second decorative piece 112 can be substantially annular, and the module cover plate 103 and the elastic shielding piece 104 can be fixedly connected to opposite ends of the second decorative piece 112 in the axial direction, respectively. The second decorative piece 112 can carry the module cover plate 103, and can also protect the module cover plate 103. A part of the second decorative piece 112 can surround the outer periphery of the module cover plate 103. The second decorative piece 112 can move up and down with the module cover plate 103, and when the second decorative piece 112 is raised and exposed, the second decorative piece 112 can play a role in appearance decoration.

[0104] As shown in FIGS. 6 and 7, the elastic barrier 104 can be substantially ring-shaped, one side of which can be fixedly connected to the second decorative member 112, and the opposite side of which can be fixedly connected to the module housing 100a (to be described below). The elastic barrier 104 has elastic deformation performance. The elastic barrier 104 can move with the second decorative member 112 and the module cover plate 103, and can be deformed when the elastic barrier 104 moves. As will be described below, the second decorative member 112 and the module cover plate 103 can be located in the hole surrounded by the first decorative member 101, and the elastic barrier 104 can be located in the inner cavity of the first decorative member 101, and the elastic barrier 104 can be used to shield the gap between the second decorative member 112 and the first decorative member 101, and can also have a certain sealing effect on the gap.

[0105] It can be understood that any one of the first decorative member 101, the second decorative member 112, and the elastic barrier 104 can be cancelled. The second decorative member 112 and the elastic barrier 104 can be an integrated structure.

[0106] FIG. 8 shows the assembly structure of the driving device 100c and the cover plate support 102 in FIG. 6. As shown in FIGS. 6 and 8, in one embodiment, the driving device 100c can include a driving source 106 and a transmission mechanism 107, the driving source 106 being connected to the transmission mechanism 107 and outputting power to the transmission mechanism 107. The transmission mechanism 107 is used to drive the cover plate support 102 to move.

[0107] In one embodiment, the driving source 106 can be a motor (or a motor) or the like that can output torque. As shown in FIG. 8, the output shaft of the driving source 106 can be substantially parallel to the XY plane, which can be referred to as the driving source 106 being laid flat in the electronic device 1000, which is conducive to reducing the occupation of the thickness space and facilitating the thinning of the electronic device 1000. A transmission member, which can be a worm or a gear, for example, can be fixed on the output shaft of the driving source 106. In another embodiment, the driving source 106 can be other driving sources, such as a hydraulic device, a piezoelectric device, an electromagnet device, etc.

[0108] In one embodiment, the transmission mechanism 107 can be a gear mechanism for transmitting torque. Illustratively, the transmission mechanism 107 can include multiple gears, such as gear 107a and gear 107b. The gear 107a and the gear 107b each have meshing teeth, and the meshing teeth of the gear 107a and the gear 107b mesh with each other. The gear 107a can mesh with a worm or a gear on the output shaft of the driving source 106, whereby the driving source 106 can output torque to the transmission mechanism 107. The gear mechanism can achieve motion reversal and can adapt to the installation posture of the cover support 102 and the driving source 106 for transmission, ensuring accurate and reliable transmission. The transmission mechanism 107 can also have a speed changing function, which can adjust the transmission ratio so that the cover support 102 moves according to the design. In another embodiment, the transmission mechanism 107 is not limited to a gear mechanism, for example, it can also be a belt transmission mechanism, a linkage mechanism, etc.

[0109] In one embodiment, as shown in FIG. 8, the driving device 100c can further include a driving member 105 and a first matching part 113. The driving member 105 connects the transmission mechanism 107 and the first matching part 113 to drive the first matching part 113 to move. The first matching part 113 is used to cooperate with the cover support 102 and drive the cover support 102 to move.

[0110] FIGS. 9 and 10 can both illustrate the structure of the driving member 105, and FIG. 10 is an exploded structure schematic view of the assembly shown in FIG. 9. As shown in FIGS. 9 and 10, the driving member 105 can be generally annular in whole. In combination with FIG. 10 and FIG. 8, the driving member 105 can surround the outer periphery of the cover support 102. As shown in FIG. 10, illustratively, the driving member 105 can include a body 105a, a first guide column 105e, and a first elastic member 105d.

[0111] In combination with FIG. 10 and FIG. 8, the body 105a can be generally annular, and the body 105a can surround the outer periphery of the cover support 102. Some areas of the body 105a can also form a generally rectangular annular structure 105f, and the inner space of the annular structure 105f is used to accommodate the first matching part 113. There can be at least one, for example, three annular structures 105f.

[0112] As shown in FIG. 10, the first guide column 105e is fixed to the body 105a, and the first guide column 105e can be located, for example, within the annular structure 105f of the body 105a. The number of the first guide column 105e in each annular structure 105f is at least one.

[0113] ​As shown in FIGS. 9 and 10, the first elastic member 105d, for example, can be located within the annular structure 105f of the body 105a, and opposite ends of the first elastic member 105d can abut against the first matching portion 113 and the body 105a, respectively. The first elastic member 105d can provide elastic force to the first matching portion 113. The number of the first elastic member 105d within each annular structure 105f can be at least one, for example, two. The first elastic member 105d includes, but is not limited to, a spring.

[0114] As shown in FIG. 10, the driving member 105 can further include a transmission portion 105b connected to the body 105a. The transmission portion 105b can extend substantially along the circumference of the body 105a, and an end of the transmission portion 105b away from the body 105a can be provided with a plurality of meshing teeth, which can also be considered as a rack. As shown in FIGS. 10 and 8, the meshing teeth of the transmission portion 105b can mesh with the meshing teeth of the gear 107b, so that the transmission mechanism 107 can transmit motion to the transmission portion 105b, thereby driving the driving member 105 to move. For the sake of distinction, the meshing teeth of the transmission portion 105b can be referred to as first meshing teeth, and the meshing teeth of the gear 107b can be referred to as second meshing teeth.

[0115] As shown in FIG. 10, the first matching portion 113 can be a pin, hereinafter referred to as the pin 113, for example. The pin 113 can be at least one, for example, two or three.

[0116] As shown in FIG. 10, the pin 113 can include a connecting portion 113b and a driving portion 113a, which are connected. The connecting portion 113b can be substantially T-shaped. The connecting portion 113b can be provided with a connecting portion through hole 113d penetrating through opposite ends of the connecting portion 113b. The connecting portion 113b can also be provided with a connecting portion through hole 113c penetrating through opposite ends of the connecting portion 113b, and the number of the connecting portion through hole 113c can be at least one, for example, two. The driving portion 113a can be substantially columnar, and the length direction of the driving portion 113a can be approximately perpendicular to the extension direction of the longitudinal portion of the T-shape. The driving portion 113a is used to form a motion cooperation with the cover bracket 102.

[0117] As shown in FIGS. 9 and 10, the pin 113 can be located within the annular structure 105f of the body 105a, and the driving portion 113a can point to the inner side of the body 105a, so as to cooperate with the cover bracket 102 (which will be described below). The first guide column 105e can pass through the connecting portion through hole 113d and be in sliding connection with the inner wall of the connecting portion through hole 113d, so that the first guide column 105e forms a sliding connection with the connecting portion 113b, that is, so that the pin 113 can slide along the first guide column 105e. Opposite ends of the first elastic member 105d can abut against the connecting portion 113b and the body 105a, respectively.

[0118] As shown in FIG. 9 and FIG. 10, in an embodiment, in order to better guide the movement of the pin 113 and the first elastic member 105d, the driving member 105 can further comprise guide posts 105c, which can be fixedly connected with the body 105a, and the guide posts 105c can be located within the annular structure 105f of the body 105a. The number of the guide posts 105c can be consistent with the number of the first elastic members 105d. One guide post 105c can correspond to one connecting portion through hole 113c, and one first elastic member 105d can correspond to the outer periphery of one guide post 105c.

[0119] In another embodiment, the structure of the pin 113 can be designed as needed, as long as the movement of the cover plate support 102 can be achieved, and the structure of the pin 113 is not limited to the above.

[0120] In another embodiment, the pin 113 and the driving member 105 can be fixedly connected, and there is no relative movement between the two. At this time, the driving member 105 can not need to be provided with the first guide post 105e, the guide post 105c and the first elastic member 105d.

[0121] The working principle of the driving device 100c will be described below.

[0122] Referring to FIG. 8 and FIG. 9, the driving source 106 can output torque to the transmission mechanism 107, the gear in the transmission mechanism 107 rotates to drive the driving member 105 to rotate around the Z axis (i.e. around the optical axis), the driving member 105 can drive the pin 113 to rotate around the Z axis (i.e. around the optical axis), and the pin 113 can drive the cover plate support 102 cooperating with the pin 113 to move (which will be described below).

[0123] The structure of the driving device 100c described above is only an example, and is not a limitation of the embodiments of the present application. For example, the driving device 100c can also not be provided with the driving member 105, or the structure of the driving member of the driving device 100c is not limited to the above, as long as the driving device 100c can achieve the movement of the pin 113.

[0124] The structure of the cover plate support 102 will be described first, and then the movement mode of the cover plate support 102 will be described.

[0125] FIG. 11 and FIG. 12 respectively show the structure of the cover plate support 102 from different perspectives, and FIG. 12 further shows the module cover plate 103. The module cover plate 103 and the cover plate support 102 can be arranged along the Z axis (i.e. the optical axis) in sequence.

[0126] As shown in FIGS. 11 and 12, the cover plate support 102 can be substantially annular, which can surround the Z axis (i.e. the optical axis) in a circle. The cover plate support 102 can have a sidewall 102a, which surrounds the Z axis, and the thickness direction of the sidewall 102a can be substantially along the radial direction of the cover plate support 102.

[0127] As shown in FIGS. 11 and 12, the cover plate support 102 can include a second matching portion 102b, which can be provided on the sidewall 102a for example. The number of the second matching portion 102b can be at least one, such as two or three, and multiple second matching portions 102b can be distributed at intervals.

[0128] As shown in FIGS. 11 and 12, the cover plate support 102 can include a second matching portion 102b, which can be provided on the sidewall 102a for example. The number of the second matching portion 102b can be at least one, such as two or three, and multiple second matching portions 102b can be distributed at intervals.

[0129] As shown in FIG. 12, in an embodiment, the groove 102b is inclined as a whole, and the distance from the groove 102b to the module cover plate 103 in the Z axis direction can increase successively from the left end to the right end of the groove 102b. The successive increase can include: the distance continuously increases from the left end to the right end of the groove 102b; and / or, the distance as a whole has an increasing trend from the left end to the right end of the groove 102b, but continuously increases at some positions and stops or decreases at other positions. For the former case, the groove 102b can be equivalent to a straight line with a certain width or a broken line with a certain width, which can include a plurality of straight lines that are not collinear. For the latter case, the groove 102b can be equivalent to a broken line with a certain width, which can include a plurality of straight lines that are not collinear.

[0130] In the following, the configuration of the groove 102b will be described taking the latter case as an example.

[0131] As shown in FIG. 12, the groove 102b can include a plurality of sub-grooves successively connected, such as a sub-groove 102d, a sub-groove 102e, a sub-groove 102f, a sub-groove 102g, and a sub-groove 102h. The inclined configuration of the groove 102b can be described by the positional relationship between the sub-grooves. The following will be described.

[0132] Any three sub-grooves in sequence connected from the plurality of sub-grooves in the groove 102b can be selected as a first sub-groove, a second sub-groove and a third sub-groove in the direction from the end of the groove 102b closer to the module cover plate 103 (for example, the left end in FIG. 12) to the end of the groove 102b farther from the module cover plate 103 (for example, the right end in FIG. 12). For example, the sub-groove 102d can be referred to as the first sub-groove, the sub-groove 102e as the second sub-groove, and the sub-groove 102f as the third sub-groove; or the sub-groove 102e can be referred to as the first sub-groove, the sub-groove 102f as the second sub-groove, and the sub-groove 102g as the third sub-groove. By analogy.

[0133] Taking the first sub-groove as the sub-groove 102d, the second sub-groove as the sub-groove 102e, and the third sub-groove as the sub-groove 102f as an example, the inclined structure of the groove 102b is described. It can be understood that the first sub-groove, the second sub-groove and the third sub-groove can be other sub-grooves.

[0134] As shown in FIG. 12, the sub-groove 102e includes opposite first and second ends d1 (for example, the left end in FIG. 12) and d2 (for example, the right end in FIG. 12), the first end d1 is connected with the sub-groove 102d, and the second end d2 is connected with the sub-groove 102f. In the Z-axis direction, the distance between the second end d2 and the module cover plate 103 can be greater than the distance between the first end d1 and the module cover plate 103. The distance between the third end d3 of the sub-groove 102f away from the sub-groove 102e and the module cover plate 103 can be approximately equal to the distance between the second end d2 and the module cover plate 103. According to the foregoing, from the left end to the right end in FIG. 12, the distances between the sub-groove 102d, the sub-groove 102e and the sub-groove 102f and the module cover plate 103 in the Z-axis direction increase in sequence.

[0135] Based on FIG. 12 and the foregoing, other structures of the groove 102b can also be obtained.

[0136] For example, referring to FIG. 12, in an embodiment, the sub-groove 102e and the sub-groove 102f can be approximately parallel (or collinear), and the sub-groove 102d can be non-parallel (or non-collinear) with the sub-groove 102e. In the Z-axis direction, the distance between the third end d3 and the module cover plate 103 can be greater than the distance between the second end d2 and the module cover plate 103.

[0137] For example, referring to FIG. 12, in another embodiment, the sub-groove 102d, the sub-groove 102e and the sub-groove 102f can be approximately parallel. In the Z-axis direction, the distance between the first end d1 and the module cover plate 103, the distance between the second end d2 and the module cover plate 103, and the distance between the third end d3 and the module cover plate 103 can continuously increase.

[0138] For example, referring to FIG. 12, the sub-groove 102d and the sub-groove 102f can be substantially parallel, and both are not parallel to the sub-groove 102e. In the direction of the Z axis, the distance between the first end d1 and the module cover plate 103 can be approximately equal to the distance between the second end d2 and the module cover plate 103, and the distance between the third end d3 and the module cover plate 103 can be greater than the distance between the second end d2 and the module cover plate 103.

[0139] As shown in FIG. 12, in an embodiment, the plurality of sub-grooves in the groove 102b can include at least one parallel sub-groove and at least one inclined sub-groove. The extension direction of the parallel sub-groove can be parallel or substantially parallel to the module cover plate 103, such as the sub-groove 102d (also referred to as the parallel sub-groove 102d), the sub-groove 102f (also referred to as the parallel sub-groove 102f), and the sub-groove 102h (also referred to as the parallel sub-groove 102h). The inclined sub-groove is inclined relative to the module cover plate 103, and the extension direction of the inclined sub-groove is not parallel to the module cover plate 103, such as the sub-groove 102e (also referred to as the inclined sub-groove 102e) and the sub-groove 102g (also referred to as the inclined sub-groove 102g). The inclined sub-grooves can be parallel to each other, or at least one inclined sub-groove is not parallel to the other inclined sub-grooves.

[0140] In the embodiment, at least one end of each parallel sub-groove is connected to an inclined sub-groove. As shown in FIG. 12, for example, the right end of the parallel sub-groove 102d is connected to the inclined sub-groove 102e. For another example, the two ends of the parallel sub-groove 102f are respectively connected to the inclined sub-groove 102e and the inclined sub-groove 102g. The inclined sub-groove 102e can be referred to as a first inclined sub-groove, the inclined sub-groove 102g can be referred to as a second inclined sub-groove, and the parallel sub-groove 102f is connected between the first inclined sub-groove and the second inclined sub-groove. The first inclined sub-groove and the second inclined sub-groove can be respectively located on opposite sides of the width direction of the parallel sub-groove 102f.

[0141] In another embodiment, the groove 102b can also not be provided with a parallel sub-groove, and the sub-grooves in the groove 102b can all be inclined sub-grooves.

[0142] The sub-grooves described above are linear as a whole and can be equivalent to a straight line. In another embodiment, at least one sub-groove can be curved and can be equivalent to a curve.

[0143] In the embodiment of the present application, the groove 102b is used to form a movement cooperation with the pin 113, which will be described below.

[0144] As shown in FIG. 11, in an embodiment, the cover support 102 can further be provided with a limiting part 102z, which can be configured in any manner, for example, as a protrusion. The number of the limiting part 102z is not limited, for example, one or more than two. In combination with FIG. 11 and FIG. 5, the limiting part 102z can be in motion cooperation with a limiting structure in the module housing 100a, which can limit the motion of the limiting part 102z, so that the limiting part 102z cannot rotate around the Z axis but can move up and down along the Z axis, thereby making the cover support 102 unable to rotate around the Z axis but able to move up and down along the Z axis. Illustratively, the limiting structure in the module housing 100a can be a sliding groove.

[0145] In combination with FIG. 8, FIG. 9 and FIG. 11, the cover support 102 can be located at the inner side of the driving member 105, and the driving part 113a of the pin 113 mounted on the driving member 105 can be inserted into the groove 102b, and the driving part 113a can be in sliding connection with the groove 102b.

[0146] In combination with FIG. 8 and FIG. 12, illustratively, the driving part 113a can be located at the left end of the groove 102b, for example, in the sub-groove 102d, when in the initial position. From the initial position, the driving device 100c can output power, so that the driving member 105 drives the pin 113 to rotate around the Z axis (i.e., around the optical axis), illustratively, in the counterclockwise direction. The driving part 113a of the pin 113 can move relative to the sub-groove 102d. Since the sub-groove 102d can be a parallel sub-groove, the force exerted by the driving part 113a on the inner wall of the sub-groove 102d along the Z axis is substantially zero, so that the driving part 113a cannot drive the cover support 102 to move up and down when moving in the sub-groove 102d. In addition, as described above, the limiting structure in the module housing 100a can limit the limiting part 102z of the cover support 102, so that the cover support 102 cannot rotate around the Z axis but can move up and down along the Z axis, and thus the driving part 113a cannot drive the cover support 102 to rotate around the Z axis when moving in the sub-groove 102d.

[0147] Therefore, when the driving part 113a moves in the sub-groove 102d, the cover support 102 can keep its initial position unchanged. It can be understood that by setting the sub-groove 102d as a parallel sub-groove, the cover support 102 can be fixed in the initial position.

[0148] With reference to FIG. 14 and FIG. 12, the driving device 100c can continue to output power, so that the driving member 105 continues to drive the pin 113 to rotate around the Z-axis, and then the driving part 113a enters the sub-groove 102e from the sub-groove 102d and moves in the sub-groove 102e. During this process, since the inner wall of the sub-groove 102e is inclined, the driving part 113a will apply a force along the positive direction of the Z-axis to the inner wall of the sub-groove 102e to drive the cover plate support 102 to move along the positive direction of the Z-axis, i.e., to make the cover plate support 102 rise. Since the cover plate support 102 remains stationary when the driving part 113a moves in the sub-groove 102d, the cover plate support 102 starts to rise when the driving part 113a moves in the sub-groove 102d. Therefore, the rising process of the cover plate support 102 corresponding to the movement of the driving part 113a in the sub-groove 102d can be referred to as the first rising of the cover plate support 102.

[0149] With reference to FIG. 14 and FIG. 12, when the driving part 113a enters the sub-groove 102f from the sub-groove 102e and moves in the sub-groove 102f, since the sub-groove 102f is a parallel sub-groove, the cover plate support 102 will maintain the current rising height unchanged, and the specific principle is the same as above, which will not be repeated here. It can be understood that by setting the sub-groove 102f as a parallel sub-groove, the cover plate support 102 can maintain the rising height after the first rising.

[0150] With reference to FIG. 15 and FIG. 12, when the driving part 113a enters the sub-groove 102g from the sub-groove 102f and moves in the sub-groove 102g, since the inner wall of the sub-groove 102g is inclined, the driving part 113a will drive the cover plate support 102 to move along the positive direction of the Z-axis, i.e., to make the cover plate support 102 continue to rise. Compared with the first rising, the rising process of the cover plate support 102 corresponding to the movement of the driving part 113a in the sub-groove 102g can be referred to as the second rising of the cover plate support 102.

[0151] With reference to FIG. 15 and FIG. 12, when the driving part 113a enters the sub-groove 102h from the sub-groove 102g and moves in the sub-groove 102h, since the sub-groove 102h is a parallel sub-groove, the cover plate support 102 will maintain the current rising height unchanged, and the specific principle is the same as above, which will not be repeated here. It can be understood that by setting the sub-groove 102h as a parallel sub-groove, the cover plate support 102 can maintain the rising height after the second rising.

[0152] According to the above, it can be understood that if the driving device 100c reversely outputs power, so that the driving member 105 drives the pin 113 to reversely rotate, the driving part 113a will drive the cover plate support 102 to descend, for example, the cover plate support 102 can descend from the height after the second rising to the initial position.

[0153] The above describes the movement of the cover bracket 102 from the initial position, the first lifting, the maintaining of the first lifting height, the second lifting, and the maintaining of the second lifting height, taking the groove 102b shown in FIG. 12 as an example. The movement of the cover bracket 102 can realize the set movement mode of the camera 111 to meet the product requirements. This will be further described below.

[0154] It can be understood that the lifting mode of the cover bracket 102 can be changed by changing the structure of the groove 102b. This will be described below.

[0155] For example, in an embodiment, the groove 102b can not contain parallel sub-grooves, and all the sub-grooves in the groove 102b are inclined sub-grooves. According to the above, it can be easily understood that the cover bracket 102 will continuously lift without the stroke of maintaining the current lifting height.

[0156] For example, in an embodiment, the groove 102b contains at least two inclined sub-grooves that are not parallel. According to the above, it can be easily understood that when the driving part 113a moves in these inclined sub-grooves that are not parallel, the lifting speed of the cover bracket 102 will not be consistent due to the different forces applied by the driving part 113a to the inner walls of the different inclined sub-grooves in the Z-axis direction. In this embodiment, the groove 102b can contain parallel sub-grooves or not contain parallel sub-grooves.

[0157] For example, in an embodiment, the groove 102b contains a curved sub-groove that can be equivalent to a curve with different slopes at different positions. According to the above, it can be easily understood that when the driving part 113a moves in the curved sub-groove, the lifting speed of the cover bracket 102 will not be constant due to the different forces applied by the driving part 113a to the inner walls of the sub-groove in the Z-axis direction at different positions.

[0158] Alternatively, referring to the description in FIG. 12, in an embodiment, a groove that is substantially mirror image of the groove 102b about the Z-axis can be designed, and the driving device 100c can be adjusted so that the driving part 113a can be located at the right end of the groove (i.e., the end closer to the module cover 103) in the initial position, and the driving device 100c can be reversed to output power, which can also drive the cover bracket 102 to lift.

[0159] Based on the above-described movement principle of the pin 113 and the groove 102b, it can be understood that in another embodiment, the positions of the pin 113 and the groove 102b can be interchanged, that is, the pin can be arranged on the cover plate support 102, or the second matching part of the cover plate support 102 can be a pin; the groove can be arranged in the driving device 100c, or the first matching part of the driving device 100c can be a groove, for example, the groove can be arranged on the inner wall of the driving member 105 facing the cover plate support 102. In this embodiment, the groove can rotate with the driving member 105, and the groove can drive the pin to rise and fall by means of the inclined inner wall of the groove, so as to realize the lifting of the cover plate support 102. The structure of the pin and the connection structure of the pin and the cover plate support 102 can be designed accordingly to meet the assembly and movement matching requirements. Illustratively, the pin on the cover plate support 102 can also be elastically supported by referring to the above-described first guide column 105e, guide column 105c, first elastic member 105d, etc.

[0160] Hereinafter, the pin 113 is connected to the driving member 105, that is, the first matching part is a pin; the groove 102b is arranged on the cover plate support 102, that is, the second matching part is a groove, which will be described in detail.

[0161] Hereinafter, the driving principle of the driving device 100c to the module cover plate 103 in the assembly structure of the entire camera module 100 will be described. In order to clearly and hierarchically show the assembly structure of the camera module 100, the assembly cross-sectional structure of the moving part 100b of the camera module 100 is first shown in FIG. 16, and then the fixed part (the module housing 100a and the first decorative member 101) of the camera module 100 is added based on FIG. 16 to obtain the assembly cross-sectional structure of the camera module 100 shown in FIG. 17.

[0162] As shown in FIG. 16, along the Z-axis direction, the module cover plate 103, the second decorative member 112, and the cover plate support 102 can be arranged in sequence. The module cover plate 103 can be fixed to one side of the second decorative member 112, and a part of the second decorative member 112 can surround the outer periphery of the module cover plate 103. The second decorative member 112 can be fixed to the cover plate support 102. One side of the elastic shielding member 104 can be fixed between the second decorative member 112 and the cover plate support 102, and the other side of the elastic shielding member 104 can be located above the driving member 105. The camera device 111 can be located on the inner side of the cover plate support 102 and below the module cover plate 103, that is, the module cover plate 103 is located on the light-entering side of the camera device 111. The assembly and matching of the driving device 100c, the driving member 105, and the cover plate support 102 have been described above, and will not be repeated here.

[0163] As shown in FIGS. 16 and 17, the moving part 100b can be accommodated in the fixed part of the camera module 100. In this embodiment, the first decorative member 101 is connected to the module housing 100a and encloses a cavity with an opening, and at least part of the moving part 100b can be located in the cavity. For example, in one embodiment, all the components of the moving part 100b except the driving source 106 can be located in the cavity, so that the driving source 106 can be connected to the cable conveniently. In another embodiment, all the components of the moving part 100b can be located in the cavity. The other side of the elastic cover 104 can be fixedly connected to the module housing 100a. The second decorative member 112 and the cover plate 103 can correspond to the opening of the cavity. The first decorative member 101 surrounds the outer periphery of the second decorative member 112.

[0164] As shown in FIG. 17, in the state, the cover plate support 102 can be in the initial position, and the second decorative member 112 and the cover plate support 102 can be substantially flush with the outer surface of the device housing 200.

[0165] As shown in FIG. 17, when the driving device 100c outputs power, the cover plate support 102 will push the second decorative member 112 and the cover plate support 102 to rise, so that the second decorative member 112 and the cover plate support 102 extend out of the opening of the cavity, as shown in FIG. 18. At this time, as shown in FIGS. 18 and 2, the second decorative member 112 and the cover plate support 102 also extend out of the opening 200a of the outer surface of the device housing 200 and protrude from the outer surface of the device housing 200 by a certain distance.

[0166] As shown in FIG. 17, when the cover plate support 102 and the second decorative member 112 and the cover plate support 102 are raised and lowered, the elastic cover 104 can be deformed accordingly. The elastic cover 104 is used to block the gap between the second decorative member 112 and the first decorative member 101 and can also have a certain sealing effect on the gap.

[0167] As described above, based on the groove 102b shown in FIG. 12, the cover plate support 102 can realize the first rising and the second rising. The movement mode of the cover plate support 102 can realize the set movement mode of the camera device 111. First, the general structure of the camera device 111 is described, and then a specific structure of the camera device 111 is described.

[0168] As shown in FIG. 6 and FIG. 19, in an embodiment, the camera 111 can include a camera body 111a and a gimbal 111b, the camera body 111a can be connected with the gimbal 111b, for example, the two can form a movable connection. The gimbal 111b can be approximately ring-shaped, for example, and can surround the outer periphery of the camera body 111a. The embodiment does not limit the specific structure of the camera body 111a and the gimbal 111b.

[0169] The camera body 111a is used to collect light and convert the image information carried by the light into an electrical signal.

[0170] The gimbal 111b is used to drive the camera body 111a to move to achieve optical image stabilization (OIS). Illustratively, the gimbal 111b can drive the camera body 111a to move through shape memory alloy (SMA) wires. The principle of OIS can be that when the camera module 100 collects light, if the electronic device 1000 shakes when in use, the camera body 111a can be driven to move by the gimbal 111b to offset the shaking stroke of the camera body 111a, to improve the positional bias of the camera body 111a due to shaking and improve the imaging quality of the camera module 100. The anti-shake achieved by driving the camera body 111a to move by the gimbal 111b can belong to large-angle anti-shake. Illustratively, the gimbal 111b can drive the camera body 111a to rotate around the X-axis and / or the Y-axis, and the angle at which the gimbal 111b drives the camera body 111a to rotate around the X-axis and / or the Y-axis can be greater than or equal to 0.8°, for example.

[0171] Illustratively, in dark light environments, long exposure, motion, and other scenarios, the gimbal 111b can drive the camera body 111a to perform OIS movement.

[0172] In another embodiment, the camera 111 can include a camera body 111a without the gimbal 111b, which can implement AF motion, or can implement AF motion and OIS motion. In this embodiment, when the module cover plate 103 rises, the distance between the camera 111 and the module cover plate 103 increases, which is beneficial to increase the stroke of AF motion, can realize multi-focus shooting, improve focusing speed, improve focusing performance in dark environment, etc., and improve imaging quality; it can also provide motion space for OIS motion of the camera body 111a to realize OIS. As shown in FIG. 11, in an embodiment, the camera module 100 can further include a limiting structure 110 connected with the cover plate support 102. In combination with FIG. 11 and FIG. 5, the limiting structure 110 is used to abut against the gimbal 111b before the second rising of the cover plate support 102, so that the gimbal 111b cannot rise and maintains the initial position. Wherein, in the initial position, the gimbal 111b can be located at the bottom of the module housing 100a away from the module cover plate 103, and the gap between the gimbal 111b and the bottom can be small, which is beneficial to make the camera module 100 have a smaller size (or thickness) along the Z-axis direction. When the gimbal 111b is limited in the initial position, the gimbal 111b will not rise, that is, the gimbal 111b will not move along the optical axis direction and approach the module cover plate 103, so that the gimbal 111b will not generate power consumption, which is beneficial to reduce the power consumption of the camera module 100.

[0173] In another embodiment, the limiting structure 110 and / or the camera 111 can be adjusted, so that the limiting structure 110 can press against any suitable position of the camera 111 before the second rising of the cover plate support 102, so as to keep the camera 111 in the initial position. In this embodiment, the camera 111 can include a camera body 111a and a gimbal 111b, or include a camera body 111a without a gimbal 111b. Illustratively, the limiting structure 110 can press against the camera body 111a before the second rising of the cover plate support 102, so that the camera 111 cannot rise and maintains the initial position. Wherein, the initial position of the camera 111 can be substantially the same as the initial position of the gimbal 111b described above.

[0174] During the second lifting of the cover support 102, the limiting structure 110 will no longer limit the camera device 111, for example, no longer limit the gimbal 111b. Illustratively, the limiting structure 110 can gradually separate from the gimbal 111b to no longer limit the gimbal 111b. Alternatively, the limiting structure 110 can contact the gimbal 111b but not apply a pressing force or a smaller pressing force to the gimbal 111b. When the gimbal 111b is not limited, the gimbal 111b can drive the camera body 111a to move along the optical axis direction from the initial position of the gimbal 111b and approach the module cover 103. The gimbal 111b can move along the optical axis direction from the initial position to a first position, and the first position is closer to the module cover 103 than the initial position. The specific height dimension of the first position can be determined as needed, and the embodiment is not limited. When the gimbal 111b moves to the first position, the gap between the gimbal 111b and the bottom of the module shell 100a can be increased. The increased gap can serve as a movement space for the camera body 111a to rotate around the X-axis and / or rotate around the Y-axis, thereby facilitating the implementation of OIS. In another embodiment, the camera device 111 can include the camera body 111a and not contain the gimbal 111b, and the camera device 111 can move along the optical axis direction from the initial position to the first position when not limited. The first position of the camera device 111 can be substantially the same as the first position of the gimbal 111b described above.

[0175] As shown in FIG. 11, in an embodiment, the limiting structure 110 can include a second elastic member 110d and a limiting member 110e. The second elastic member 110d has elastic deformation performance, which can be a spring, for example. The number of second elastic members 110d is at least one, for example, which can be two. The structure of the limiting member 110e can be designed as needed, and the embodiment is not limited.

[0176] As shown in FIG. 11 and FIG. 13(a), the cover support 102 can be located at a position before the second lifting, for example, at the initial position. The opposite ends of the second elastic member 110d can abut the cover support 102 and the limiting member 110e, respectively. In combination with FIG. 11, FIG. 13(a) and FIG. 5, the end of the limiting member 110e away from the second elastic member 110d can abut the gimbal 111b. Thus, the cover support 102 will press the limiting member 110e through the second elastic member 110d, so that the limiting member 110e presses the gimbal 111b, thereby limiting the gimbal 111b.

[0177] Referring to FIG. 13(a) and FIG. 5, when the cover support 102 gradually rises from the initial position, the pressure of the cover support 102 on the second elastic member 110d can be reduced, so that the rebound force of the second elastic member 110d can be reduced, the pressure on the limiting member 110e can be reduced, and thus the pressure of the limiting member 110e on the gimbal 111b can also be reduced. When the cover support 102 completes the first rising and is about to perform the second rising, the pressure of the limiting member 110e on the gimbal 111b can be substantially zero, and at this time, the limiting member 110e and the gimbal 111b can be in a critical state. When the cover support 102 performs the second rising, the limiting member 110e will no longer limit the gimbal 111b. For example, the limiting member 110e will gradually separate from the gimbal 111b, or the limiting member 110e can be in contact with the gimbal 111b, but the pressing force of the limiting member 110e on the gimbal 111b is zero or small. At this time, the gimbal 111b can rise to leave a movement space for OIS movement.

[0178] As shown in FIG. 13(b), in an embodiment, the limiting member 110e can include a limiting plate 110f and a limiting column 110g, the limiting plate 110f and the limiting column 110g are connected, and the limiting column 110g can extend substantially along the thickness direction of the limiting plate 110f. In combination with FIG. 13(b), FIG. 11 and FIG. 5, the opposite ends of the second elastic member 110d are respectively abutted against the cover support 102 and the limiting plate 110f, and the end of the limiting column 110g away from the second elastic member 110d is used to abut against the gimbal 111b. The limiting member 110e of this structure can better connect the second elastic member 110d and the gimbal 111b, and can ensure reliable transmission of the abutting pressure.

[0179] As shown in FIG. 13(b), in an embodiment, the limiting structure 110 can further include a frame body 110a, the frame body 110a can be substantially C-shaped, the frame body 110a and the cover support 102 can surround a receiving space, and the receiving space can be substantially rectangular, for example. The frame body 110a can be provided with a frame body through hole 110c. In combination with FIG. 13(b) and FIG. 11, the second elastic member 110d and the limiting plate 110f are both located in the receiving space, and the limiting column 110g passes through the frame body through hole 110c and is in sliding connection with the frame body 110a. The scheme of this embodiment can realize reliable assembly of the cover support 102 and the limiting structure 110, so that the assembled structure is relatively compact.

[0180] As shown in FIG. 13(b), in an embodiment, the limiting structure 110 can further include guide posts 110b, which can be accommodated in the accommodation space, and the guide posts 110b can connect the cover plate support 102 and the frame 110a. The number of the guide posts 110b can be consistent with the number of the second elastic members 110d, and one second elastic member 110d can correspond to the outer periphery of one guide post 110b. The limiting plate 110f can further have through holes 110h, and the number of the through holes 110h can be consistent with the number of the guide posts 110b. As shown in FIG. 13(b) and FIG. 11, one guide post 110b can correspond to one through hole 110h, so that the limiting member 110e can slide along the guide post 110b. The guide posts 110b can guide the movement of the second elastic members 110d and the limiting member 110e, thereby ensuring the assembly reliability. As described above, when the cover plate support 102 is lifted for the second time, the gimbal 111b can be lifted. The following will list a specific way to realize the lifting of the gimbal 111b.

[0181] As shown in FIG. 19, in an embodiment, the camera module 100 can further include a pop-up structure 108, which can include a base 108d and a third elastic member 108c. The structure of the base 108d is not limited, for example, it can be generally annular block-shaped. The base 108d is fixedly arranged, for example, it can be fixedly arranged in the module housing 100a, as shown in FIG. 19 and FIG. 5. The third elastic member 108c has elastic deformation performance, for example, it can be a spring. The number of the third elastic member 108c is at least one. As shown in FIG. 19 and FIG. 5, the opposite ends of the third elastic member 108c can abut against the base 108d and the gimbal 111b, respectively.

[0182] In the embodiment, the number of the pop-up structure 108 can be at least one, for example, three pop-up structures 108 are shown in FIG. 19, and the three pop-up structures 108 can be arranged at different positions of the gimbal 111b. Illustratively, the three pop-up structures 108 can be arranged at equal intervals.

[0183] As shown in FIG. 5, when the cover plate support 102 is at the initial position, the gimbal 111b is also at the initial position and is pressed by the limiting structure 110. At this time, the gimbal 111b will press the third elastic member 108c, so that the third elastic member 108c is in a compressed state, and the distance between the gimbal 111b and the base 108d is small.

[0184] As shown in FIG. 5, when the cover plate support 102 is lifted from the initial position and completes the first lifting, the gimbal 111b continues to be pressed by the limiting structure 110 to maintain its initial position. Therefore, the third elastic member 108c continues to be in the compressed state, and the distance between the gimbal 111b and the base 108d remains unchanged.

[0185] Referring to FIG. 5, during the second lifting of the cover support 102, the limiting structure 110 no longer limits the gimbal 111b, and the pressure of the third elastic member 108c on the gimbal 111b decreases. Referring to FIG. 20, the third elastic member 108c will gradually extend and push the gimbal 111b to rise along the Z-axis direction (i.e., the optical axis direction), so that the gimbal 111b drives the camera body 111a to approach the module cover 103.

[0186] As shown in FIG. 19, in an embodiment, the gimbal 111b can further be provided with at least one camera device through hole 111c. As shown in FIGS. 19 and 20, the pop-up structure 108 can further include a stopper 108a and a second guide column 108b. The structure of the stopper 108a is not limited, for example, it can be roughly strip-shaped or block-shaped. The number of the second guide column 108b is at least one. One second guide column 108b can correspond to passing through one camera device through hole 111c and be in sliding connection with the gimbal 111b. The second guide column 108b connects the stopper 108a and a base 108d, and the stopper 108a and the base 108d are respectively located on opposite sides of the gimbal 111b along the Z-axis direction (i.e., the optical axis direction). The length of the stopper 108a can be greater than the aperture of the camera device through hole 111c. Illustratively, the third elastic member 108c can be sleeved on the outer periphery of the second guide column 108b.

[0187] As shown in FIG. 5, when the gimbal 111b is located at the initial position, the stopper 108a has a certain spacing with the gimbal 111b. When the gimbal 111b starts to rise, the spacing between the stopper 108a and the gimbal 111b can gradually decrease. As shown in FIG. 20, when the gimbal 111b rises to the maximum height, the spacing between the stopper 108a and the gimbal 111b can be roughly zero, and the stopper 108a can contact the gimbal 111b. Since the base 108d is fixed, the stopper 108a can block the gimbal 111b from continuing to rise, so that the gimbal 111b remains at the height position.

[0188] In another embodiment, the camera device 111 and / or the pop-up structure 108 can be adjusted, so that the third elastic member 108c can abut against any suitable position of the camera device 111, for example, it can abut against the camera body 111a; the stopper 108a can be arranged at any suitable position, for example, near the camera body 111a. Illustratively, the camera device through hole 111c can be arranged at any suitable position of the camera device 111. For example, the camera device through hole 111c can be arranged on the camera body 111a. Wherein, the pop-up structure 108 can be installed at the camera device through hole 111c at this position, for example, the camera device through hole 111c on the camera body 111a.

[0189] It can be understood from the above that the ascended holder 111b can be limited in any other suitable manner, and is not limited to the stopper 108a and the second guide column 108b.

[0190] The structure of the holder in an embodiment will be described below. It can be understood that this is only an example, and the holder of the embodiments of the present application is not limited thereto.

[0191] FIG. 21 is a schematic diagram of an assembled structure of the camera 111 in an embodiment, FIG. 22 is a schematic diagram of an exploded structure of the camera 111 shown in FIG. 21, and FIG. 23 is a schematic diagram of an exploded structure of a partial assembly structure in FIG. 22.

[0192] As shown in FIGS. 21 and 22, the camera 111 can include a holder 111b and a camera body 111a. The camera body 111a is movably connected with the holder 111b. For ease of description, the width direction of the camera 111 can be defined as the X axis, the length direction of the camera 111 can be defined as the Y axis, and the thickness direction of the camera 111, i.e., the optical axis direction, can be defined as the Z axis. For example, the Y axis direction is defined as the first direction, the X axis direction is defined as the second direction, and the Z axis is defined as the third direction. In other embodiments, the first direction, the second direction, and the third direction are not specifically limited, as long as the first direction, the second direction, and the third direction are different from each other. It can be understood that the coordinate system of the camera 111 can be flexibly set according to actual needs.

[0193] The camera body 111a is used to collect light and convert image information carried by the light into an electrical signal.

[0194] As shown in FIGS. 21 and 22, the holder 111b can drive the camera body 111a to rotate around a first rotation axis P1 and can also drive the camera body 111a to rotate around a second rotation axis P2. The extension direction of the first rotation axis P1, the extension direction of the second rotation axis P2, and the optical axis direction are different from each other. It can be understood that the first rotation axis P1 and the second rotation axis P2 can be an extension of a physical axis or an extension of a virtual axis.

[0195] As shown in FIG. 21, the first rotation axis P1 can extend along the X-axis direction, and the second rotation axis P2 can extend along the Y-axis direction. The optical axis of the camera 111 can extend along the Z-axis direction. It can be understood that the gimbal 111b can control the camera body 111a to rotate around the first rotation axis P1, or to rotate around the second rotation axis P2, or to rotate around both the first rotation axis P1 and the second rotation axis P2. For example, when the gimbal 111b controls the camera body 111a to rotate around the first rotation axis P1, the camera body 111a can rotate in a plane perpendicular to the X-axis direction (i.e., the Y-Z plane) because the first rotation axis P1 extends along the X-axis direction. When the gimbal 111b controls the camera body 111a to rotate around the second rotation axis P2, the camera body 111a can rotate in a plane perpendicular to the Y-axis direction (i.e., the X-Z plane) because the second rotation axis P2 extends along the Y-axis direction.

[0196] When the camera 111 captures light, if the electronic device 1000 is subject to an external force and thus shakes, the gimbal 111b can control the camera body 111a to rotate around the X-axis and / or around the Y-axis to offset the shaking stroke of the camera body 111a, so as to avoid or reduce the positional deviation of the camera body 111a caused by the shaking. In other words, the camera 111 can control the camera body 111a to rotate around the X-axis and / or around the Y-axis by the gimbal 111b, so as to realize the OIS of the camera 111 and improve the imaging quality of the camera 111. It can be understood that the anti-shake of the camera body 111a controlled by the gimbal 111b can belong to large-angle anti-shake. For example, the angle of the camera body 111a controlled by the gimbal 111b to rotate around the X-axis and / or around the Y-axis can be greater than 0.8°.

[0197] The camera body 111a can have any shape. As shown in FIG. 22, the camera body 111a can include a first side surface 211, a second side surface 212, and a third side surface 213. The first side surface 211 and the second side surface 212 can be opposite to each other, and the third side surface 213 can be located between the first side surface 211 and the second side surface 212. It can be understood that each of the above-mentioned side surfaces can be an outer surface of the camera body 111a.

[0198] As shown in FIG. 22, the camera body 111a can further include a first rotating shaft (not shown in FIG. 22 due to the angle of view) and a second rotating shaft 216. The first rotating shaft is protruded from the first side surface 211 of the camera body 111a. The second rotating shaft 216 is protruded from the second side surface 212 of the camera body 111a. The first rotating shaft and the second rotating shaft 216 can be on the same straight line, i.e., the first rotating shaft and the second rotating shaft 216 are collinear. The extension line of the center line of the first rotating shaft or the extension line of the center line of the second rotating shaft 216 can constitute the first rotating axis P1. Exemplarily, the first rotating shaft and the second rotating shaft 216 can be parallel to the X-axis direction.

[0199] As shown in FIG. 22, the camera body 111a further includes a first protruding block 217. Exemplarily, the first protruding block 217 is protruded from the third side surface 213 of the camera body 111a. In another embodiment, the first protruding block 217 can be arranged at any external surface of the camera body 111a.

[0200] As shown in FIG. 22, the camera body 111a can further include a module circuit board 218, which is used to electrically connect with an external circuit to realize power supply and / or signal transmission of the camera 111.

[0201] The structure of the camera body 111a is described above in detail in combination with the related drawings. The structure of the holder 111b and the connection relationship between the holder 111b and the camera body 111a will be described below in detail in combination with the related drawings.

[0202] FIG. 23 is an exploded structural schematic view of the holder 111b shown in FIG. 22.

[0203] As shown in FIG. 23, the holder 111b includes a first carrier 11, a second carrier 12, a first driving mechanism 13 and a second driving mechanism 14. It can be understood that FIG. 23 and the related drawings below only show some components in the holder 111b, and the actual shape, actual size, actual position and actual structure of these components in the drawings are only exemplary and are not a limitation on the embodiments of the present application.

[0204] As shown in FIG. 23, illustratively, the first carrier 11 can be substantially a polygonal frame structure. The outer surface of the first carrier 11 can be provided with the second protrusion 118. The outer surface of the first carrier 11 can also be provided with a third rotation axis 1161 and a fourth rotation axis (not shown in the perspective of FIG. 23). The third rotation axis 1161 and the fourth rotation axis can be oppositely arranged, and the third rotation axis 1161 and the fourth rotation axis can be on the same straight line, i.e., the third rotation axis 1161 and the fourth rotation axis are collinear. The extension line of the center line of the third rotation axis 1161 or the extension line of the center line of the fourth rotation axis can constitute the second rotation axis P2. Illustratively, the third rotation axis 1161 and the fourth rotation axis can be integrally formed with the first carrier 11. The first carrier 11 can also be provided with a first avoiding hole 117, which can pass through the first carrier 11 and can form an opening on both the inner surface and the outer surface of the first carrier 11. The first avoiding hole 117 can be located on the same side of the first carrier 11 as the third rotation axis 1161, for example, on the same outer surface of the first carrier 11. The inner surface of the first carrier 11 can also be provided with a first rotation axis slot (not shown in the perspective of FIG. 23) and a second rotation axis slot 1152, which can be oppositely arranged. The second rotation axis slot 1152 can be located on the same side of the first carrier 11 as the second protrusion 118, for example.

[0205] FIG. 24 is an exploded structural schematic view of the first driving mechanism 13 shown in FIG. 23. As shown in FIG. 24, illustratively, the first driving mechanism 13 includes a first shape memory alloy (SMA) wire 131, a second SMA wire 132, a first jaw 133, a second jaw 134, and a third jaw 135. The first SMA wire 131 and the second SMA wire 132 can constitute a first group of SMA wires 130. It can be understood that the first driving mechanism 13 can also include more or fewer structures. For example, the first driving mechanism 13 can also not include at least one of the second SMA wire 132, the first jaw 133, the second jaw 134, the third jaw 135, etc.

[0206] As shown in FIG. 24, the first jaw 133 includes a first fixed part 1331 and a second fixed part 1332 connected thereto. Illustratively, the first fixed part 1331 can be in the shape of a plate. The second fixed part 1332 can be in the shape of a bend.

[0207] As shown in FIG. 24, the third jaw 135 is similar to the first jaw 133 in structure, and the structures of the two can be symmetrical or partially symmetrical. Illustratively, the third jaw 135 and the first jaw 133 are symmetrical structures, and the configuration and connection relationship of the third jaw 135 can be referred to the description of the first jaw 133. For example, the third jaw 135 includes a first fixed part 1351 and a second fixed part 1352 connected to each other. It can be understood that the third jaw 135 can also be slightly different from the first jaw 133 in detailed structure and / or connection design.

[0208] As shown in FIG. 24, the second jaw 134 includes a first fixed part 1341, a second fixed part 1342, and a third fixed part 1343. The second fixed part 1342 and the third fixed part 1343 are oppositely arranged at intervals, and both can be connected to the first fixed part 1341. Illustratively, the shape of the first fixed part 1341 can be plate-shaped. The shapes of the second fixed part 1342 and the third fixed part 1343 can be bent.

[0209] In this embodiment, the first SMA wire 131 and the second SMA wire 132 are made of SMA material, such as nickel-titanium alloy material. Among them, SMA is a general term for a class of metals with shape memory effect.

[0210] Referring to FIG. 24, the first end 1311 of the first SMA wire 131 can be fixed to the second fixed part 1332 of the first jaw 133, and the second end 1312 of the first SMA wire 131 can be fixed to the second fixed part 1342 of the second jaw 134.

[0211] As shown in FIG. 25, illustratively, the extension direction of the first SMA wire 131 is arranged at an angle with the first rotation axis P1. For example, the angle A between the extension direction of the first SMA wire 131 and the first rotation axis P1 satisfies: 0°<A≤90°. Illustratively, the angle A satisfies: 10°<A≤30°. It can be understood that in order to clearly show the angle A between the extension direction of the first SMA wire 131 and the first rotation axis P1, FIG. 25 moves the extension direction of the first SMA wire 131 and the first rotation axis P1 to the same plane to form the angle A.

[0212] Referring to FIG. 24, the first end 1321 of the second SMA wire 132 is fixed to the second fixed part 1352 of the third jaw 135, and the second end 1322 of the second SMA wire 132 is fixed to the third fixed part 1343 of the second jaw 134. There can be a gap between the second SMA wire 132 and the first SMA wire 131, and at least a part of the second SMA wire 132 is not in contact with the first SMA wire 131 (the opposite also holds), for example, all parts of the second SMA wire 132 are not in contact with the first SMA wire 131.

[0213] As shown in FIG. 25, the extension direction of the second SMA wire 132 is set at an angle with the first rotation axis P1. As shown in FIG. 25, the angle B between the extension direction of the second SMA wire 132 and the first rotation axis P1 satisfies: 0° < B ≤ 90°. As an example, the angle B satisfies: 10° < B ≤ 30°. It can be understood that, in order to clearly show the angle B between the extension direction of the second SMA wire 132 and the first rotation axis P1, FIG. 25 moves the extension direction of the second SMA wire 132 and the first rotation axis P1 to the same plane to form the angle B.

[0214] In an embodiment, the projection of the second SMA wire 132 and the first SMA wire 131 on the first reference plane intersect each other, wherein the first rotation axis P1 and the optical axis direction of the camera 111 are both parallel to the first reference plane, and the first reference plane may, for example, be the X-Z plane in FIG. 25. In another embodiment, the projection of the second SMA wire 132 and the first SMA wire 131 on the first reference plane may also not intersect.

[0215] As shown in FIG. 22 and FIG. 25, the first carrier 11 can be wrapped around the outside of the camera body 111a, and at least a part of the camera body 111a can be located inside the first carrier 11. The second rotation shaft 216 of the camera body 111a can be inserted into the second rotation shaft slot 1152 of the first carrier 11 and rotationally connected with the second rotation shaft slot 1152. The first rotation shaft of the camera body 111a can be inserted into the first rotation shaft slot of the first carrier 11 and rotationally connected with the first rotation shaft slot. Thus, the camera body 111a can be rotationally connected with the first carrier 11 through the first rotation shaft and the second rotation shaft 216. The first rotation shaft and the second rotation shaft 216 can form the first rotation axis P1 of the camera body 111a, and the camera body 111a can rotate relative to the first carrier 11 around the first rotation axis P1. As an example, since the first rotation shaft and the second rotation shaft 216 can be parallel to the X-axis direction, the camera body 111a can rotate relative to the first carrier 11 around the X-axis in the Y-Z plane.

[0216] In another embodiment, the positions of the first rotation shaft of the camera body 111a and the first rotation shaft slot of the first carrier 11 can be reversed, that is, the first rotation shaft slot can be arranged on the camera body 111a, and the first rotation shaft can be arranged on the first carrier 11. The positions of the second rotation shaft of the camera body 111a and the second rotation shaft slot of the first carrier 11 can be reversed, that is, the second rotation shaft slot can be arranged on the camera body 111a, and the second rotation shaft can be arranged on the first carrier 11.

[0217] As shown in FIG. 22 and FIG. 25, the first protrusion 217 of the camera body 111a can cooperate with the first avoiding hole 117 of the first carrier 11, and at least a part of the first protrusion 217 can be located inside the first avoiding hole 117.

[0218] As shown in FIG. 24 and FIG. 25, the first fixed part 1331 of the first clamping jaw 133 is fixed to the camera body 111a. For example, the first fixed part 1331 of the first clamping jaw 133 is fixed to the first protrusion 217 of the camera body 111a. In another embodiment, the first clamping jaw 133 can be fixed to any position of the camera body 111a.

[0219] As shown in FIG. 24 and FIG. 25, the first fixed part 1341 of the second clamping jaw 134 is fixed to the first carrier 11. The line between the second fixed part 1332 of the first clamping jaw 133 and the second fixed part 1342 of the second clamping jaw 134 is arranged at an angle with the first rotation axis P1.

[0220] As shown in FIG. 24 and FIG. 25, the first fixed part 1351 of the third clamping jaw 135 is fixed to the camera body 111a and is arranged at an interval from the first clamping jaw 133, i.e., the third clamping jaw 135 does not contact the first clamping jaw 133. The line between the second fixed part 1352 of the third clamping jaw 135 and the third fixed part 1343 of the second clamping jaw 134 can be arranged at an angle with the first rotation axis P1. For example, the first fixed part 1351 of the third clamping jaw 135 is fixed to the first protrusion 217 of the camera body 111a. The first fixed part 1351 of the third clamping jaw 135 is fixedly connected to the camera body 111a through the first protrusion 217. For example, in the view angle of FIG. 25, the second fixed part 1352 of the third clamping jaw 135 is located at the lower part of the second fixed part 1332 of the first clamping jaw 133. The third fixed part 1343 of the second clamping jaw 134 is located at the upper part of the second fixed part 1342 of the second clamping jaw 134.

[0221] In this embodiment, the first clamping jaw 133, the second clamping jaw 134 and the third clamping jaw 135 are all made of conductive material.

[0222] As shown in FIG. 25, for example, the first end 1311 of the first SMA wire 131 is electrically connected to the module circuit board 218 of the camera body 111a through the conductive part (not shown in the figure) in the first clamping jaw 133 and the camera body 111a. The first end 1321 of the second SMA wire 132 is electrically connected to the module circuit board 218 through the conductive part in the third clamping jaw 135 and the camera body 111a. In other embodiments, when the shape, length, etc. of the first clamping jaw 133 allow, the first end 1311 of the first SMA wire 131 can also be directly electrically connected to the module circuit board 218 of the camera body 111a through the first clamping jaw 133. When the shape, length, etc. of the third clamping jaw 135 allow, the first end 1321 of the second SMA wire 132 can also be directly electrically connected to the module circuit board 218 through the third clamping jaw 135.

[0223] As shown in FIG. 24 and FIG. 25, in an embodiment, the first SMA wire 131 and the second SMA wire 132 can be simultaneously supplied with the first current, and the first SMA wire 131 and the second SMA wire 132 can contract. The first SMA wire 131 can apply a first pulling force to the camera body 111a through the first claw 133 (the direction of the first pulling force is schematically shown by a solid line a1 with an arrow in FIG. 25). The first pulling force can generate a first component force in the negative direction of the Z axis and a second component force in the negative direction of the X axis. The second SMA wire 132 can apply a second pulling force to the camera body 111a through the third claw 135 (the direction of the second pulling force is schematically shown by a solid line a2 with an arrow in FIG. 25). The second pulling force can generate a third component force in the positive direction of the Z axis and a fourth component force in the negative direction of the X axis. The first component force and the third component force can substantially cancel each other out. The second component force and the fourth component force can cause the camera body 111a to move in the negative direction of the X axis, so that the second rotating shaft 216 (see FIG. 22) can be locked in the second rotating shaft slot 1152 (see FIG. 10) in the negative direction of the X axis. At this time, the camera body 111a can be in a balanced state.

[0224] When the current through the first SMA wire 131 is controlled to be greater than the current through the second SMA wire 132, for example, by increasing the current through the first SMA wire 131 and / or decreasing the current through the second SMA wire 132, the first SMA wire 131 can contract and / or the second SMA wire 132 can lengthen. At this time, the first component force is greater than the third component force, and the camera body 111a can rotate clockwise about the X axis relative to the first carrier 11 (the clockwise direction about the X axis is schematically shown by a dashed line b1 with an arrow in FIG. 25).

[0225] When the current through the second SMA wire 132 is controlled to be greater than the current through the first SMA wire 131, for example, by decreasing the current through the first SMA wire 131 and / or increasing the current through the second SMA wire 132, the first SMA wire 131 can lengthen and / or the second SMA wire 132 can contract. At this time, the third component force is greater than the first component force, and the camera body 111a can rotate counterclockwise about the X axis relative to the first carrier 11 (the counterclockwise direction about the X axis is schematically shown by a dashed line b2 with an arrow in FIG. 25).

[0226] For example, the camera body 111a can rotate about the first rotating axis P1 relative to the first carrier 11 through an angle in a range of 0.8° to 4°, such as 1°, 2°, 3°, 4°, etc.

[0227] In an embodiment, when the first SMA wire 131 contracts by about 100 microns (0.1 millimeter), the first end 1311 of the first SMA wire 131 can drop by about 600 microns (0.6 millimeter) along the Z-axis direction. At this time, the magnification of the first SMA wire 131 is about 6 times. In this way, the gimbal 111b can control the camera body 111a to rotate by a large angle clockwise around the X-axis relative to the first carrier 11. Similarly, the magnification of the second SMA wire 132 can also be about 6 times. In this way, the gimbal 111b can control the camera body 111a to rotate by a large angle counterclockwise around the X-axis relative to the first carrier 11.

[0228] As shown in FIGS. 24 and 25, when the first SMA wire 131 is energized and contracts, the first SMA wire 131 can exert a first pulling force on the camera body 111a through the first claw 133 (the direction of the first pulling force is schematically shown by a solid line a1 with an arrow in FIG. 25). The first pulling force can generate a first component force along the negative direction of the Z-axis and a second component force along the negative direction of the X-axis. The first component force can be used to make the camera body 111a rotate along a first circumferential direction around the X-axis relative to the first carrier 11. It can be understood that the present embodiment describes the first circumferential direction as the clockwise direction. FIG. 12 also schematically shows the clockwise direction around the X-axis by a dashed line b1 with an arrow. In addition, the second component force can be used to make the camera body 111a move along the negative direction of the X-axis. At this time, the second rotating shaft 216 (see FIG. 22) will also be stuck in the second rotating shaft slot 1152 (see FIG. 23) along the negative direction of the X-axis, thereby limiting the displacement of the camera body 111a in the XY plane during the rotation of the camera body 111a due to the assembly gap.

[0229] As shown in FIGS. 24 and 25, when the second SMA wire 132 contracts, the second SMA wire 132 can exert a second pulling force on the camera body 111a through the third claw 135 (the direction of the second pulling force is schematically shown by a solid line a2 with an arrow in FIG. 25). The second pulling force can generate a third component force along the positive direction of the Z-axis and a fourth component force along the negative direction of the X-axis. The third component force can make the camera body 111a rotate along a second circumferential direction around the X-axis relative to the first carrier 11. The second circumferential direction is opposite to the first circumferential direction. It can be understood that the present embodiment describes the second circumferential direction as the counterclockwise direction. FIG. 25 schematically shows the counterclockwise direction around the X-axis by a dashed line b2 with an arrow. In addition, the fourth component force can make the camera body 111a move along the negative direction of the X-axis. At this time, the second rotating shaft 216 (see FIG. 22) will also be stuck in the second rotating shaft slot 1152 (see FIG. 23) along the negative direction of the X-axis, thereby limiting the displacement of the camera body 111a in the XY plane during the rotation of the camera body 111a due to the assembly gap.

[0230] As shown in FIG. 23, the second carrier 12 can be generally a polygonal frame structure, illustratively. The second carrier 12 can also be provided with a second avoiding hole 126, which can pass through the second carrier 12 and can form openings on both the inner surface and the outer surface of the second carrier 12. The inner surface of the second carrier 12 can also be provided with a third rotating shaft slot (not shown in the view of FIG. 23) and a fourth rotating shaft slot 1252, which can be oppositely arranged.

[0231] As shown in FIG. 26, the second driving mechanism 14 includes a third SMA wire 141, a fourth SMA wire 142, a fourth claw 143, a fifth claw 144, and a sixth claw 145. The third SMA wire 141 and the fourth SMA wire 142 constitute the second group of SMA wires 140. It can be understood that the second driving mechanism 14 can also include more or fewer structures. For example, the second driving mechanism 14 can also not include at least one of the fourth SMA wire 142, the fourth claw 143, the fifth claw 144, the sixth claw 145, and the like.

[0232] In this embodiment, the fourth claw 143 of the second driving mechanism 14 can be arranged in the same manner as the second claw 134 of the first driving mechanism 13. For example, the fourth claw 143 includes a first fixed part 1431, a second fixed part 1432, and a third fixed part 1433. Details are not repeated here.

[0233] In this embodiment, the fifth claw 144 of the second driving mechanism 14 can be arranged in the same or similar manner as the first claw 133 of the first driving mechanism 13, and the sixth claw 145 of the second driving mechanism 14 can be arranged in the same or similar manner as the third claw 135 of the first driving mechanism 13. For example, the fifth claw 144 includes a first fixed part 1441 and a second fixed part 1442. The sixth claw 145 includes a first fixed part 1451 and a second fixed part 1452. Details are not repeated here.

[0234] In this embodiment, the third SMA wire 141 and the fourth SMA wire 142 of the second driving mechanism 14 are arranged in the same or similar manner as the first SMA wire 131 and the second SMA wire 132 of the first driving mechanism 13, which are not repeated here.

[0235] As shown in FIG. 26, the first end 1411 of the third SMA wire 141 is fixed to the second fixed part 1432 of the fourth claw 143, and the second end 1412 of the third SMA wire 141 is fixed to the second fixed part 1442 of the fifth claw 144. It can be understood that the extension direction of the third SMA wire 141 is arranged at an angle with the second rotation axis P2. Exemplarily, as shown in FIG. 27, the angle C between the extension direction of the third SMA wire 141 and the second rotation axis P2 satisfies: 0°<C≤90°, for example, the angle C between the extension direction of the third SMA wire 141 and the second rotation axis P2 satisfies: 10°<C≤30°. It can be understood that, in order to clearly show the angle C between the extension direction of the third SMA wire 141 and the second rotation axis P2, FIG. 27 moves the extension direction of the third SMA wire 141 and the second rotation axis P2 to the same plane to form the angle C.

[0236] As shown in FIG. 26, the first end 1421 of the fourth SMA wire 142 is fixed to the third fixed part 1433 of the fourth claw 143, and the second end 1422 of the fourth SMA wire 142 is fixed to the second fixed part 1452 of the sixth claw 145. It can be understood that the extension direction of the fourth SMA wire 142 is arranged at an angle with the second rotation axis P2. As shown in FIG. 27, exemplarily, the angle D between the extension direction of the fourth SMA wire 142 and the second rotation axis P2 satisfies: 0°<D≤90°. For example, the angle D between the extension direction of the fourth SMA wire 142 and the second rotation axis P2 satisfies: 10°<C≤30°. It can be understood that, in order to clearly show the angle D between the extension direction of the fourth SMA wire 142 and the second rotation axis P2, FIG. 27 moves the extension direction of the fourth SMA wire 142 and the second rotation axis P2 to the same plane to form the angle D.

[0237] Exemplarily, the projection of the fourth SMA wire 142 and the third SMA wire 141 on the second reference plane is cross arrangement, and the optical axis direction of the camera 111 and the second rotation axis P2 are both parallel to the second reference plane. For example, the second reference plane can be Y-Z plane. In other embodiments, the projection of the fourth SMA wire 142 and the third SMA wire 141 on the second reference plane can also not need to be cross arrangement.

[0238] As shown in FIG. 27, the second carrier 12 can surround the first carrier 11, and the first carrier 11 can be located inside the second carrier 12. As shown in FIG. 27 and FIG. 23, at least a portion of the third rotating shaft 1161 of the first carrier 11 can be located in the third rotating shaft slot of the second carrier 12, and rotatably connected to the slot wall of the third rotating shaft slot. At least a portion of the fourth rotating shaft of the first carrier 11 can be located in the fourth rotating shaft slot 1252 of the second carrier 12, and rotatably connected to the slot wall of the fourth rotating shaft slot 1252. Thus, the first carrier 11 can be rotatably connected to the second carrier 12 through the third rotating shaft 1161 and the fourth rotating shaft. The third rotating shaft 1161 and the fourth rotating shaft can form the second rotating axis P2 of the camera body 111a. The first carrier 11 and the camera body 111a can rotate around the second rotating axis P2 relative to the second carrier 12.

[0239] As shown in FIG. 27 and FIG. 23, the second protrusion 118 of the first carrier 11 can cooperate with the second avoiding hole 126 of the second carrier 12, and at least a portion of the second protrusion 118 can be located in the second avoiding hole 126.

[0240] As shown in FIG. 27 and FIG. 26, the first fixed part 1431 of the fourth claw 143 can be fixed to the first carrier 11. Illustratively, the first fixed part 1431 can be fixed to the second protrusion 118 of the first carrier 11. In other embodiments, the position of the fourth claw 143 fixed to the first carrier 11 is not specifically limited.

[0241] As shown in FIG. 27 and FIG. 26, the first fixed part 1441 of the fifth claw 144 is fixed to the second carrier 12. The line between the second fixed part 1432 of the fourth claw 143 and the second fixed part 1442 of the fifth claw 144 can be arranged at an angle with the second rotating axis P2.

[0242] As shown in FIG. 27 and FIG. 26, the first fixed part 1451 of the sixth claw 145 is fixed to the second carrier 12, and is arranged spaced apart from the fifth claw 144, i.e. the sixth claw 145 does not contact the fifth claw 144. The line between the second fixed part 1452 of the sixth claw 145 and the third fixed part 1433 of the fourth claw 143 is arranged at an angle with the second rotating axis P2. Illustratively, in the perspective of FIG. 27, the third fixed part 1433 of the fourth claw 143 can be located below the second fixed part 1432 of the fourth claw 143, and the second fixed part 1452 of the sixth claw 145 is located above the second fixed part 1442 of the fifth claw 144.

[0243] In this embodiment, the fourth claw 143, the fifth claw 144 and the sixth claw 145 are all made of conductive material.

[0244] As shown in FIG. 27, the second end 1412 of the third SMA wire 141 is electrically connected to the module circuit board 218 of the camera body 111a through the fifth claw 144, a conductive member (not shown) in the second carrier 12, and a first flexible electrical connection member (not shown), exemplarily. The first flexible electrical connection member (not shown) can be a flexible circuit board, an elastic member (such as a spring or a spring sheet), a wire, etc. One end of the first flexible electrical connection member (not shown) is fixed to the second carrier 12, and the other end is fixed to the module circuit board 218. In other embodiments, when the shape, length, etc. of the fifth claw 144 allows, the second end 1412 of the third SMA wire 141 can also be directly electrically connected to the module circuit board 218 through the fifth claw 144.

[0245] As shown in FIG. 27, the second end 1422 of the fourth SMA wire 142 is electrically connected to the module circuit board 218 of the camera body 111a through the sixth claw 145, a conductive member (not shown) in the second carrier 12, and a second flexible electrical connection member (not shown), exemplarily. The second flexible electrical connection member (not shown) can be a flexible circuit board, an elastic member (such as a spring or a spring sheet), a wire, etc. One end of the second flexible electrical connection member (not shown) is fixed to the second carrier 12, and the other end is fixed to the module circuit board 218. In an embodiment, the second flexible electrical connection member (not shown) and the first flexible electrical connection member (not shown) can be an integrally formed structure. In other embodiments, when the shape, length, etc. of the sixth claw 145 allows, the second end 1422 of the fourth SMA wire 142 can also be directly electrically connected to the module circuit board 218 through the sixth claw 145.

[0246] As shown in FIG. 27, the third SMA wire 141 and the fourth SMA wire 142 can be caused to transmit the first current at the same time, and the third SMA wire 141 and the fourth SMA wire 142 will generate contraction. The third SMA wire 141 can exert a third pulling force on the first carrier 11 through the fourth claw 143. The third pulling force can generate a fifth component force in the negative direction of the Z axis and a sixth component force in the negative direction of the Y axis. The fourth SMA wire 142 can exert a fourth pulling force on the first carrier 11 through the fourth claw 143. The fourth pulling force can generate a seventh component force in the positive direction of the Z axis and an eighth component force in the negative direction of the Y axis. The fifth component force and the seventh component force can be approximately cancelled out. The sixth component force and the eighth component force can cause the first carrier 11 and the camera body 111a to move in the negative direction of the Y axis. At this time, the fourth rotation shaft of the first carrier 11 can be stuck in the fourth rotation shaft slot 1252 (see FIG. 23) along the negative direction of the Y axis.

[0247] When the current on the third SMA wire 141 is controlled to be greater than the current on the fourth SMA wire 142, for example, the current on the third SMA wire 141 is increased and / or the current on the fourth SMA wire 142 is decreased, the third SMA wire 141 shortens and / or the fourth SMA wire 142 lengthens. At this time, the fifth component force is greater than the seventh component force, and the first carrier 11 and the camera body 111a can rotate clockwise about the Y axis relative to the second carrier 12.

[0248] When the current on the fourth SMA wire 142 is controlled to be greater than the current on the third SMA wire 141, for example, the current on the third SMA wire 141 is decreased and / or the current on the fourth SMA wire 142 is increased, the third SMA wire 141 lengthens and / or the fourth SMA wire 142 shortens. At this time, the seventh component force is greater than the fifth component force, and the first carrier 11 and the camera body 111a can rotate counterclockwise about the Y axis relative to the second carrier 12.

[0249] Exemplarily, the angle by which the first carrier 11 and the camera body 111a rotate about the second rotation axis P2 relative to the second carrier 12 is greater than 0.8°. For example, the angle is in the range of 1° to 4°, such as 1°, 3°, 4°, etc.

[0250] In an embodiment, when the third SMA wire 141 contracts by about 100 microns (i.e., 0.1 millimeter), the first end 1411 of the third SMA wire 141 can descend along the Z axis by about 600 microns (i.e., 0.6 millimeter). At this time, the magnification of the second driving mechanism 14 is about 6 times. In this way, the gimbal 111b can control the camera body 111a to rotate clockwise about the Y axis relative to the first carrier 11 by a large angle. Similarly, the magnification of the fourth SMA wire 142 can also be about 6 times. In this way, the gimbal 111b can control the camera body 111a to rotate counterclockwise about the Y axis relative to the first carrier 11 by a large angle.

[0251] As shown in FIG. 27, when the third SMA wire 141 generates contraction, the third SMA wire 141 can exert a third pulling force on the first carrier 11 through the fourth clamping jaw 143 (FIG. 27 schematically shows the direction of the third pulling force by a solid line with an arrow c1). The third pulling force can generate a fifth component force in the negative direction of the Z axis and a sixth component force in the negative direction of the Y axis. The fifth component force can be used to rotate the first carrier 11 and the camera body 111a relative to the second carrier 12 in a third circumferential direction around the Y axis. It can be understood that the present embodiment describes the third circumferential direction as the clockwise direction. FIG. 27 schematically shows the clockwise direction around the Y axis by a dashed line with an arrow d1. In addition, the sixth component force can be used to move the first carrier 11 and the camera body 111a in the negative direction of the Y axis. At this time, the fourth rotating shaft of the first carrier 11 can be clamped in the fourth rotating shaft slot 1252 in the negative direction of the Y axis, so as to limit the displacement of the first carrier 11 and the camera body 111a in the XY plane during the rotation of the first carrier 11 and the camera body 111a due to the assembly gap.

[0252] As shown in FIG. 27, when the fourth SMA wire 142 generates contraction, the fourth SMA wire 142 can exert a fourth pulling force on the first carrier 11 through the fourth clamping jaw 143 (FIG. 27 schematically shows the direction of the fourth pulling force by a solid line with an arrow c2). The fourth pulling force can generate a seventh component force in the positive direction of the Z axis and an eighth component force in the negative direction of the Y axis. The seventh component force can be used to rotate the first carrier 11 and the camera body 111a relative to the second carrier 12 in a fourth circumferential direction around the Y axis. The fourth circumferential direction is opposite to the third circumferential direction. It can be understood that the present embodiment describes the fourth circumferential direction as the counterclockwise direction. FIG. 27 schematically shows the counterclockwise direction around the Y axis by a dashed line with an arrow d2. In addition, the eighth component force can be used to move the first carrier 11 and the camera body 111a in the negative direction of the Y axis. At this time, the fourth rotating shaft of the first carrier 11 can be clamped in the fourth rotating shaft slot 1252 in the negative direction of the Y axis, so as to limit the displacement of the first carrier 11 and the camera body 111a in the XY plane during the rotation of the first carrier 11 and the camera body 111a due to the assembly gap.

[0253] The above describes a gimbal 111b. By arranging the first carrier 11 around the camera body 111a and the second carrier 12 around the first carrier 11, the camera body 111a, the first carrier 11 and the second carrier 12 are arranged in a nested manner. In this way, in the Z axis direction, the camera body 111a, the first carrier 11 and the second carrier 12 all have overlapping regions, and the structure of the camera body 111a, the first carrier 11 and the second carrier 12 is more compact, thereby facilitating improvement of the space utilization rate in the Z axis direction.

[0254] It can be understood that the first carrier 11 can be rotatably connected to the camera body 111a through the first rotation axis P1, and rotatably connected to the second carrier 12 through the second rotation axis P2, so that the relative rotation direction of the second carrier 12 and the first carrier 11 is different from the relative rotation direction of the first carrier 11 and the camera body 111a. In other words, on the one hand, the first carrier 11 can cooperate with the second carrier 12 to act as a stator for the rotation of the camera body 111a around the first rotation axis P1, and on the other hand, the first carrier 11 can act as a rotor for the rotation of the camera body 111a around the second rotation axis P2. In this way, the first carrier 11 has the function of "one thing with multiple uses". The first carrier 11 can play a role of structural reuse, so as to simplify the structure of the gimbal 111b, thereby realizing the miniaturized design of the gimbal 111b.

[0255] It can be understood that in the process of the user using the electronic device 1000 to take a picture, if the user's hand shake causes the camera 111 to deviate. At this time, the first driving mechanism 13 of the gimbal 111b can control the camera body 111a to rotate relative to the first carrier 11 around the first rotation axis P1, and / or the second driving mechanism 14 can control the first carrier 11 and the camera body 111a to rotate relative to the second carrier 12 around the second rotation axis P2, thereby canceling the shaking stroke (for example, the deviation of the camera body 111a along the X-axis direction, the deviation along the Y-axis direction, or the rotation in the X-Y plane, etc.) of the camera body 111a, to avoid or reduce the positional bias of the camera body 111a caused by shaking, thereby improving the imaging quality of the camera 111. Compared with the image sensor anti-shake and lens anti-shake scheme, the gimbal 111b controls the camera body 111a to rotate around the X-axis and / or rotate around the Y-axis, thereby realizing optical image anti-shake of the camera 111. The anti-shake scheme of the present application is stable in full image quality whether it is a small angle or a large angle. In other words, the anti-shake scheme of the present application can avoid edge pixel blur and reduce the cutting ratio when anti-shaking (i.e. the picture can not need to be cut). In addition, the anti-shake scheme of the present application can also be suitable for long exposure scenes.

[0256] It can be understood that compared with the scheme of the driving mechanism of eight SMA wires, the first driving mechanism 13 and the second driving mechanism 14 of the present embodiment can adopt a structure of four SMA wires. On the one hand, the process of the structure of four SMA wires is relatively simple, and the possibility of mass production is higher. On the other hand, the power consumption is lower.

[0257] It can be understood that by setting the extension direction of the first SMA wire 131 to be at an angle with the first rotation axis P1, when the first SMA wire 131 generates contraction, the pulling force exerted by the first SMA wire 131 on the camera body 111a can generate a second component force in the negative direction of the X axis. The second component force can be used to move the camera body 111a in the negative direction of the X axis. At this time, the second rotating shaft 216 will also be stuck in the second rotating shaft slot 1152 in the negative direction of the X axis, so as to limit the displacement of the camera body 111a in the XY plane due to the assembly gap during the rotation of the camera body 111a.

[0258] Similarly, when the second SMA wire 132 generates contraction, the pulling force exerted by the second SMA wire 132 on the camera body 111a can generate a fourth component force in the negative direction of the X axis. The fourth component force can be used to move the camera body 111a in the negative direction of the X axis. At this time, the second rotating shaft 216 will also be stuck in the second rotating shaft slot 1152 in the negative direction of the X axis, so as to limit the displacement of the camera body 111a in the XY plane due to the assembly gap during the rotation of the camera body 111a.

[0259] Similarly, when the third SMA wire 141 generates contraction, the pulling force exerted by the third SMA wire 141 on the first carrier 11 can generate a sixth component force in the negative direction of the Y axis. The sixth component force can be used to move the first carrier 11 and the camera body 111a in the negative direction of the Y axis. At this time, the fourth rotating shaft of the first carrier 11 can be stuck in the fourth rotating shaft slot 1252 in the negative direction of the Y axis, so as to limit the displacement of the first carrier 11 and the camera body 111a in the XY plane due to the assembly gap during the rotation of the first carrier 11 and the camera body 111a.

[0260] Similarly, when the fourth SMA wire 142 generates contraction, the pulling force exerted by the fourth SMA wire 142 on the first carrier 11 can generate an eighth component force in the negative direction of the Y axis. The eighth component force can be used to move the first carrier 11 and the camera body 111a in the negative direction of the Y axis. At this time, the fourth rotating shaft of the first carrier 11 can be stuck in the fourth rotating shaft slot 1252 in the negative direction of the Y axis, so as to limit the displacement of the first carrier 11 and the camera body 111a in the XY plane due to the assembly gap during the rotation of the first carrier 11 and the camera body 111a.

[0261] It can be understood that the second carrier 12 can not only be a stator of the component of the camera device 111, but also protect the first carrier 11, the first driving mechanism 13 and the second driving mechanism 14 of the holder 111b. In this way, when the camera device 111 is applied to the electronic device 1000, the second carrier 12 of the holder 111b can be directly fixed on the structural member (for example, the device shell 200) of the electronic device 1000. In this way, compared with the camera device 111 scheme in the prior art: the outer part of the holder 111b of the camera device 111 needs to be provided with a shell, and the camera device 111 is packaged and fixed on the structural member (for example, the shell or the middle frame) of the electronic device 1000 through the shell. In the embodiment, since the second carrier 12 of the holder 111b can be directly fixed on the structural member (for example, the shell or the middle frame) of the electronic device 1000, the camera device 111 can no longer need to be additionally provided with a shell, thereby further simplifying the structure of the camera device 111, thereby facilitating the miniaturization of the camera device 111. In addition, the step of packaging and fixing the camera device 111 on the structural member (for example, the device shell 200) of the electronic device 1000 through the shell can be omitted, thereby reducing the cost investment.

[0262] The structure of the camera body 111a will be described below. The camera body 111a to be shown in the following various drawings can have different, similar or the same structure as the camera body 111a described above. It can be understood that this is only an example, and the structure of the camera body 111a is not strictly limited in the embodiments of the present application.

[0263] FIGS. 28 to 30 show the structure of the camera body 111a according to an embodiment, wherein FIG. 28 is an assembly structure diagram of the camera body 111a, FIG. 29 is an exploded structure diagram of the camera body 111a in FIG. 28, and FIG. 30 is an exploded structure diagram of a partial assembly structure in FIG. 29. It can be understood that the shape structure of the camera body 111a shown in FIGS. 28 to 30 is only an example and is not a limitation of the embodiments.

[0264] As shown in FIGS. 28 to 30, the camera body 111a can include a cover body 111d, a bottom plate 111j, a lens assembly 111s, a first support 111g, a second support 111h, and a motor, an image sensor and the like.

[0265] The cover body 111d and the bottom plate 111j can enclose a cavity. The lens assembly 111s, the first support 111g, the second support 111h, and the focus motor and the anti-shake motor and the like can be substantially accommodated in the cavity.

[0266] The cover body 111d can also be referred to as a case. Illustratively, the cover body 111d can be provided with a second rotating shaft 111z, which can be rotationally connected with the holder 111b described above.

[0267] The bottom plate 111j can also be referred to as a base. The bottom plate 111j can be connected with a circuit board, which can reinforce the circuit board to enhance structural strength. Alternatively, the bottom plate 111j can also be provided with a circuit, and the bottom plate 111j can serve as a circuit board.

[0268] As shown in FIG. 30, the first support 111g can surround the outer periphery of the lens assembly 111s and be fixedly connected with the lens assembly 111s. The first support 111g can drive the lens assembly 111s to move along the optical axis direction, or be referred to as an auto focus (AF) movement. The light exit side of the lens assembly 111s can be provided with an image sensor, and the lens assembly 111s is used to project light onto the image sensor.

[0269] As shown in FIG. 29 and FIG. 30, in an embodiment, the camera body 111a can further include a variable aperture 111e, which can be arranged on the light entrance side of the lens assembly 111s. The variable aperture 111e has an aperture hole, the size of which can be automatically adjusted. Light can enter the lens assembly 111s through the aperture hole of the variable aperture 111e. The variable aperture 111e is used to adjust the amount of light entering, so that the camera module 100 can maintain good imaging quality under various brightness conditions. In another embodiment, the variable aperture 111e can also be omitted.

[0270] As shown in FIG. 30, the second support 111h can surround the outer periphery of the first support 111g, and the second support 111h is used to drive the first support 111g and the lens assembly 111s to move to achieve OIS (which will be described below). The second support 111h is movably connected with the first support 111g.

[0271] In an embodiment, the bottom plate 111j can be provided with a plurality of balls, and the second support 111h can be in rolling contact with the balls. Thus, the second support 111h can move relative to the bottom plate 111j through the balls to achieve OIS. The balls can be arranged at a plurality of positions of the bottom plate 111j, and each position can be provided with at least one ball. It can be understood that the movement of the second support 111h relative to the bottom plate 111j can be achieved by any other suitable means, which is not limited to the above.

[0272] As shown in FIG. 29 and FIG. 30, in an embodiment, the camera body 111a can further include a guide rod 111n, which can extend substantially along the Z-axis direction. The guide rod 111n can be fixed to the second support 111h. The number of guide rods 111n can be at least one, for example, two. A plurality of guide rods 111n can be fixed to different positions of the second support 111h, respectively. The guide rod can be made of ceramic material, for example.

[0273] As shown in FIG. 29 and FIG. 30, the first bracket 111g can be in contact with the guide rod 111n. For example, a magnet can be arranged in the first bracket 111g, and the magnet can be magnetically attracted to the guide rod 111n, so that the first bracket 111g can be in contact with the guide rod 111n. The first bracket 111g is also in sliding connection with the guide rod 111n, and the first bracket 111g can slide along the guide rod 111n, and the guide rod 111n can guide the first bracket 111g. In this way, the second bracket 111h can be movably connected to the first bracket 111g through the guide rod 111n.

[0274] By arranging the guide rod 111n, a larger stroke (for example, about 1mm) and a larger load (for example, 700mg or more) of AF movement can be achieved. In addition, the friction of the first bracket 111g sliding along the guide rod 111n is small, which can ensure that the AF movement and the OIS movement are relatively smooth and reliable. It can be understood that the second bracket 111h and the first bracket 111g can also be movably connected in other ways, which are not limited to the above.

[0275] As shown in FIG. 29, in an embodiment, the camera body 111a can further include an elastic column 111k (also referred to as a suspension wire) and a spring sheet 111m. The elastic column 111k can extend substantially along the Z-axis direction, and the elastic column 111k can connect the bottom plate 111j and the second bracket 111h. The elastic column 111k can have elastic bending deformation performance and can also conduct electricity. The spring sheet 111m can connect the elastic column 111k and the variable aperture 111e, and the spring sheet 111m can have elastic deformation performance and can also conduct electricity. Through the elastic column 111k and the spring sheet 111m, the variable aperture 111e can be powered, and elastic restoring force can also be provided (which will be described below).

[0276] In an embodiment, the motor is an integrated anti-shake focusing motor. The motor can drive the lens assembly 111s to move along the Z-axis direction to achieve auto focus (AF), and the motor can also drive the lens assembly 111s to move along a plane perpendicular to the Z-axis direction (i.e., the XY plane) to achieve OIS. Illustratively, the motor can be a voice coil motor, i.e., a motor that generates driving force through the cooperation of a coil and a magnet. This will be described below.

[0277] FIG. 31 is a perspective assembly structure schematic diagram of the second bracket 111h, the first bracket 111g, the bottom plate 111j, and the motor, and FIG. 32 is a top view structure schematic diagram of the assembly shown in FIG. 31.

[0278] As shown in FIG. 30 and FIG. 31, the motor can include a first driving assembly M1, which can include a first coil 111r, a magnet 111u and a second coil 111f, which can be arranged in sequence in a radial direction. Illustratively, the first coil 111r can be fixed to a side of the first support 111g away from the lens assembly 111s; the magnet 111u can be fixed to a side of the second support 111h facing the first coil 111r, and the magnet 111u is located between the second support 111h and the first coil 111r; and the second coil 111f can be fixed to the bottom plate 111j. Illustratively, the first coil 111r, the magnet 111u and the second coil 111f can be placed vertically, i.e., the thickness direction of the first coil 111r and the second coil 111f can be substantially parallel to the bottom plate 111j, or in other words, substantially parallel to the XY plane.

[0279] The first coil 111r can be referred to as an AF coil. When the first coil 111r is energized, a first Lorentz force can be generated under the action of the magnet 111u, the first Lorentz force acts on the first coil 111r along the optical axis direction, thereby driving the first support 111g and the lens assembly 111s to move along the optical axis direction, and thus AF is realized.

[0280] The second coil 111f can be referred to as an OIS coil. When the second coil 111f is energized, a second Lorentz force can be generated under the action of the magnet 111u, the second Lorentz force can act along the XY plane, for example, the second Lorentz force can act along the X-axis direction. The second Lorentz force can act on the magnet 111u, thereby driving the second support 111h, the first support 111g and the lens assembly 111s to move along the XY plane, for example, along the X-axis direction, and thus OIS is realized.

[0281] In this embodiment, the first coil 111r and the second coil 111f can share the magnet 111u, which can reduce the amount of magnet used, be conducive to reducing the weight of the camera module 100, and also increase the structural compactness of the camera module 100 and reduce the volume of the camera module 100.

[0282] As shown in FIG. 30 and FIG. 31, the motor can further include a second driving assembly M2, which can be arranged apart from the first driving assembly M1, for example, approximately at a 90-degree angle. The second driving assembly M2 can include a first coil 111t, a magnet 111v, and a second coil 111i, which can be arranged in sequence in a radial direction. Illustratively, the first coil 111t can be fixed to a side of the first support 111g facing away from the lens assembly 111s; the magnet 111v can be fixed to a side of the second support 111h facing the first coil 111t, and the magnet 111v is located between the second support 111h and the first coil 111t; and the second coil 111i can be fixed to the bottom plate 111j. Illustratively, the first coil 111t, the magnet 111v, and the second coil 111i can be placed vertically, i.e., the thickness direction of the first coil 111t and the second coil 111i can be approximately parallel to the bottom plate 111j, or in other words, approximately parallel to the XY plane.

[0283] The first coil 111t can be referred to as an AF coil. When the first coil 111t is energized, a first Lorentz force can be generated under the action of the magnet 111v, the first Lorentz force acts on the first coil 111t along the optical axis direction, thereby driving the first support 111g and the lens assembly 111s to move along the optical axis direction, and thus AF is achieved. By providing two groups of AF coils, i.e., the first coil 111t and the first coil 111r, the lens assembly 111s can be driven to move for AF more balanced. It can be understood that at least one group of AF coils can be provided.

[0284] The second coil 111i can be referred to as an OIS coil. When the second coil 111i is energized, a third Lorentz force can be generated under the action of the magnet 111v, the third Lorentz force can act on the magnet 111v along the XY plane, for example, along the Y-axis direction. The third Lorentz force can drive the second support 111h, the first support 111g, and the lens assembly 111s to move along the XY plane, for example, along the Y-axis direction, and thus OIS is achieved. Thus, by providing the second coil 111f and the second coil 111i, OIS movement along the X-axis direction and along the Y-axis direction can be achieved, respectively, so that the lens assembly 111s can move along the XY plane for OIS.

[0285] In this embodiment, the first coil 111t and the second coil 111i can share the magnet 111v, which can reduce the amount of magnets used, be conducive to reducing the weight of the camera module 100, and increase the compactness of the camera module 100 and reduce the volume of the camera module 100.

[0286] As shown in FIG. 31 and FIG. 32, in an embodiment, the motor can further include a third driving assembly M3, which can be disposed diagonally to the first driving assembly M1, for example, and both can be disposed at two ends of a diagonal line of the bottom plate 111j respectively. The third driving assembly M3 can include a magnet 111p and a coil, the magnet 111p and the coil can be stacked along the optical axis direction, the magnet 111p can be fixed to the second support 111h, and the coil can be fixed to the bottom plate 111j. The third driving assembly M3 can cooperate with the first driving assembly M1 to realize OIS movement, and the Lorentz force generated by the third driving assembly M3 can be substantially in the same direction as the Lorentz force generated by the first driving assembly M1. The Lorentz force generated by the third driving assembly M3 can be larger. By disposing the third driving assembly M3 and the first driving assembly M1, sufficient driving force can be provided to the lens assembly 111s, and the lens assembly 111s can be driven more balanced to realize OIS movement.

[0287] As shown in FIG. 31 and FIG. 32, in an embodiment, the motor can further include a fourth driving assembly M4, which can be disposed diagonally to the second driving assembly M2, for example, and both can be disposed at two ends of a diagonal line of the bottom plate 111j respectively. The fourth driving assembly M4 can include a magnet 111q and a coil, the magnet 111q and the coil can be stacked along the optical axis direction, the magnet 111q can be fixed to the second support 111h, and the coil can be fixed to the bottom plate 111j. The fourth driving assembly M4 can cooperate with the second driving assembly M2 to realize OIS movement, and the Lorentz force generated by the fourth driving assembly M4 can be substantially in the same direction as the Lorentz force generated by the second driving assembly M2. The Lorentz force generated by the fourth driving assembly M4 can be larger. By disposing the fourth driving assembly M4 and the second driving assembly M2, sufficient driving force can be provided to the lens assembly 111s, and the lens assembly 111s can be driven more balanced to realize OIS movement.

[0288] When the second support 111h moves for OIS, the elastic column 111k and the reed 111m can be elastically deformed. On the one hand, the elastic force provided by the elastic column 111k and the reed 111m can make the OIS movement accurate and reliable, so that the second support 111h can move according to the designed path and avoid position offset; on the other hand, the elastic force provided by the elastic column 111k and the reed 111m can also serve as a restoring force, so that the second support 111h can restore to the original position when powered off.

[0289] The above takes the motor of the camera body 111a as an example of a voice coil motor. In another embodiment, the motor can be other types of motors, such as an SMA motor, i.e., a motor driven by the expansion and contraction force of a shape memory alloy.

[0290] In the embodiment, the first support 111g can move along the optical axis direction and the XY plane, and the second support 111h can move along the XY plane. In order to reduce the impact or abnormal sound caused by the movement, an anti-collision structure can be arranged at a suitable position. The anti-collision structure can have a certain elastic deformation performance, for example, can be made of silicone (for example, soft glue) and the like. Illustratively, in combination with FIG. 29 and FIG. 28, the anti-collision structure can be arranged on the surface of the first support 111g facing the cover body 111d, and / or arranged on the surface of the second support 111h facing the OIS coil (for example, the second coil 111f, the second coil 111i, etc.). The anti-collision structure can also play a role in buffering vibration absorption, reducing abnormal sound when the camera module 100 is subjected to external impact.
