Description

Lifting device, camera module and electronic equipment Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a lifting device, a camera module and an electronic device. Background Art

[0002] Mobile phones, tablets, laptops, and wearable devices all have camera modules to enable video recording. This functionality has gradually become a key feature of these products and a key performance indicator for evaluating these devices. With the continuous development of electronic devices, the trend towards thinner and lighter devices has also become a major development trend.

[0003] To meet the demand for camera functionality, thinner, and more aesthetically pleasing devices, the camera module can be designed with a retractable structure. When the camera module is in use, at least a portion of the camera module can be driven to extend from the housing of the electronic device, increasing the optically available space inside the camera module and achieving high-quality camera functionality. When the camera module is no longer in use, at least a portion of the camera module can be driven to retract from the exterior of the housing toward the interior, reducing the thickness of the camera module and contributing to the thinness and aesthetics of the electronic device.

[0004] However, the buffer design of the lifting type camera module is not smooth enough in scenarios such as pressing and falling, and buffer jamming and failure are prone to occur, resulting in damage to the camera module and electronic equipment.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a lifting device, a camera module and an electronic device. The lifting device can achieve high-reliability buffering, ensure the smoothness of buffering, solve problems such as buffering jamming and failure, and can more reliably resist external impact forces in scenarios such as falling and pressing.

[0007] The first aspect of the embodiments of the present application provides a lifting device, including a lifting member, a rotating member and a linkage member, wherein the rotating member can be rotatably arranged. One of the rotating member and the lifting member has an integrally formed main body and mounting portion, the main body and the mounting portion enclose a storage space, the linkage member is at least partially arranged in the storage space, the linkage member cooperates with the other of the rotating member and the lifting member, and the rotating member is used to drive the lifting member to move toward or away from the rotating member along the thickness direction through the linkage member during the rotation process, thereby realizing the extension and retraction of the lifting device, so that the lifting device has a retracted state and an extended state. When the lifting device is in the retracted state, the thickness of the lifting device is relatively small, which is conducive to thinning. When the lifting device is in the extended state, the internal space of the lifting device is relatively large, and the optically available space of the camera device located inside is relatively large, thereby obtaining excellent shooting quality.

[0008] The lifting device also includes an elastic member and at least two guide members. The elastic member and at least two guide members are both located in the accommodating space. The elastic member is located between the linkage member and the main body. In buffering scenarios such as falling and pressing, when external force is transmitted to the lifting member, elastic member and rotating member, the elastic expansion and contraction of the elastic member can play a good buffering role, reducing or avoiding damage to the lifting member, rotating member, etc.

[0009] The linkage part is located on at least two guide parts, and the at least two guide parts are used to make the linkage part slide along the thickness direction. The guide parts are used to limit the moving direction of the linkage part, ensuring that in scenarios where buffering is achieved such as falling and pressing, the linkage part only slides along the thickness direction, and does not tilt forward and backward (along the radial direction of rotation of the rotating part), tilt left and right (along the tangential direction of rotation of the rotating part), or rotate around the conductive part, thereby improving the smoothness of buffering under impact and avoiding problems such as buffering jamming and buffering failure caused by scratches between the linkage part and the rotating part.

[0010] The elastic part is located on at least one of the at least two guide parts. The guide part provided with the elastic part also has a guiding effect on the elastic part, so that the elastic part elastically expands and contracts along the thickness direction, which is beneficial to ensure the smoothness of the movement of the linkage part along the thickness direction during elastic buffering, and is also beneficial to improving the smoothness of buffering under impact.

[0011] Furthermore, the mounting portion and the main body are an integrated structure, providing a highly secure bond. Positioning the linkage member within the space enclosed by the mounting portion and the main body significantly enhances the secure assembly of the elastic member and linkage member on the rotating member. This reduces or eliminates damage to the mounting portion (the top wall of the mounting portion) caused by the elastic member's rebound, further avoiding buffering issues and improving reliability in resisting impact forces in buffering scenarios such as drops and pressure.

[0012] A first through hole is provided on at least one of the mounting portion and the main body portion, and the guide member can pass through the through hole and be fixed in the through hole, so that the guide member can be fixed in the accommodating space surrounded by the mounting portion and the main body portion, thereby realizing the assembly and fixation of the guide member, and also realizing the assembly of the linkage member and the elastic member. The assembly operation is simple, and the installation is easy to realize, and it can be realized without the need for additional assembly parts, which is conducive to reducing the component structure and reducing costs. It also does not occupy space in the thickness direction, and is conducive to the thinning design of the lifting device.

[0013] In a possible implementation, the at least two guide members include a first guide member and a second guide member, the linkage member includes a connected matching portion and a first extension portion, and the linkage member matches with the other of the rotating member and the lifting member through the matching portion.

[0014] The mating portion is disposed around the first guide member, and the first extension portion is disposed around the second guide member, with the thickness of the mating portion being greater than that of the first extension portion. That is, in the thickness direction, the distance between the mating portion and the first guide member for achieving guiding engagement is greater than the distance between the first extension portion and the second guide member. The guiding effect between the first guide member and the mating portion is superior to the guiding effect between the first extension portion and the second guide member. The first guide member enables precise positioning of the mating portion (i.e., the linkage member), while the second guide member enables coarse positioning of the first extension portion (i.e., the linkage member). The combination of the two ensures smooth guiding in buffering scenarios, helps reduce installation precision requirements and installation difficulty, improves assemblability, and facilitates assembly.

[0015] In one possible implementation, an elastic member is disposed around the second guide member, located between the first extension portion and the main body. No elastic member is disposed on the first guide member, which includes the mating portion. Because the mating portion is inherently thicker, and given the requirement for a relatively low overall height of the rotating member, the elastic member is located on the second guide member. This ensures a longer extension path for the elastic member, achieving a more effective cushioning effect. This ensures a cushioning effect while reducing the thickness of the rotating member and the entire lifting device.

[0016] In a possible implementation, the at least two guide members further include a third guide member, and the third guide member and the second guide member are respectively located on both sides of the first guide member along the rotation direction of the rotating member.

[0017] The linkage also includes a second extension, which surrounds the third guide. An elastic member surrounds the third guide and is located between the second extension and the main body. This allows for three guides and two elastic members within a single mounting portion, achieving a superior cushioning effect and providing stable guidance during the cushioning process, enhancing the smoothness of the cushioning process.

[0018] In a possible implementation, the thickness of the second extension portion is smaller than the thickness of the matching portion.

[0019] In one possible implementation, the ratio of the thickness of the mating part to the thickness of the first extension part is 3.5 to 5, and the ratio of the thickness of the mating part to the thickness of the second extension part is 3.5 to 5. The structure of the linkage part is reasonably designed to enable the linkage part and the guide part to better achieve guiding cooperation by using precise positioning and coarse positioning, with high buffering smoothness and high mass production assembly performance.

[0020] In one possible implementation, the gap between the inner surface of the mating part and the outer surface of the first guide member is 5 μm to 10 μm, which further improves the guiding accuracy of the first guide member to the mating part (linkage member), ensures the precise positioning and guiding of the linkage member by the first guide member, and better improves the smoothness of the buffering.

[0021] In one possible implementation, the gap between the inner surface of the first extension part and the outer surface of the second guide part is 20μm to 30μm, and the gap between the inner surface of the second extension part and the outer surface of the third guide part is 20μm to 30μm, thereby realizing the rough positioning and guiding of the linkage part by the second guide part and the third guide part, ensuring high buffering smoothness while better facilitating assembly.

[0022] In one possible implementation, the mounting portion includes a top wall, which is opposite to the main body. The top wall and the main body respectively have a first through hole, and both ends of the guide member are respectively fixed in the first through holes, thereby improving the flexibility of the guide member assembly.

[0023] In a possible implementation, the top wall has a first groove on a side facing away from the main body, the first through hole is located on the bottom wall of the first groove, the lifting device further includes a first connecting member, and the guide member is fixed in the first through hole via the first connecting member.

[0024] The first connector is located in the first groove, which can facilitate positioning during assembly. On the other hand, the recessed first groove can free up space in the thickness direction, allowing the first connector to be fixed in the first groove, thereby reducing or avoiding the space occupied by the first connector in the thickness direction.

[0025] In a possible implementation, the main body includes a top surface and an outer side surface, the top surface is opposite to the top wall of the mounting portion, and the outer side surface may be located outside the top surface.

[0026] There is a first positioning groove on the top surface and an opening on the outer surface. The opening is connected to the first positioning groove. During assembly, the elastic part can be inserted into the first positioning groove through the opening to achieve precise positioning of the elastic part assembly, and it is also convenient for the guide part to be installed and coordinated with the elastic part.

[0027] In one possible implementation, a second positioning groove is provided on the top surface, and the first guide member is positioned within the second positioning groove. The second positioning groove can assist in the precise assembly of the first guide member and the linkage member. For example, when assembling the linkage member within the accommodation space, the second positioning groove can be aligned with the mating portion, thereby improving the precise positioning of the linkage member and facilitating the sheathing and mating of the first guide member with the mating portion during installation.

[0028] In one possible implementation, a protruding first slider is provided on the mating part, and a first slide rail is provided on the other of the rotating part and the lifting part. The first slide rail is at least partially inclined relative to the thickness direction. The first slider is inserted into the first slide rail and slides along the first slide rail.

[0029] In a possible implementation, a flexible conductive member is further included, which includes a first connection end, an elastic telescopic section, and a second connection end connected in sequence, the first connection end is electrically connected to the lifting member, and the second connection end is electrically connected to the base.

[0030] The elastic expansion section includes a bend section and multiple cantilever sections. The cantilever sections are spaced apart, alternating between the cantilever sections and the bend sections, with two adjacent cantilever sections connected by a bend section. This elastic expansion section, similar to a spring structure, has a flexible margin of motion. This allows it to extend or contract under external force, preventing the flexible conductive member from interfering with the lifting element's movement.

[0031] In a possible implementation, a driving mechanism and a transmission mechanism are further included. The transmission mechanism cooperates with the driving mechanism and the rotating member respectively, and the driving mechanism drives the rotating member to rotate through the transmission mechanism.

[0032] In a possible implementation, the device further includes a base, in which the rotating member is rotatably arranged. The lifting device further includes a cover plate, which is arranged on the base and has an avoidance hole for the lifting member to pass through.

[0033] An accommodating cavity is formed between the cover plate and the base, and at least the transmission mechanism is arranged in the accommodating cavity, and the transmission mechanism is connected to the cover plate and the base respectively.

[0034] In a possible implementation, the cover plate includes a first cover body and a second cover body, the first cover body is provided with a second through hole, and the second cover body is assembled on the second through hole, that is, the first cover body and the second cover body are two independent structural parts assembled together.

[0035] The first cover is fixed to the base, and the second cover is fixed to the transmission mechanism. This decouples the alignment tolerances of the cover and base assembly from those of the cover and transmission mechanism. The assembly clearance between the first and second covers absorbs the alignment tolerances caused by the first cover and base assembly, ensuring precise alignment of the second cover and transmission mechanism. This prevents the shaft from skewing during assembly due to excessive positioning holes or over-positioning, ensuring effective transmission.

[0036] In one possible implementation, the second cover includes a fixed portion and a raised portion. The fixed portion is provided with a raised portion protruding from one side of the fixed portion, and the fixed portion is fixed to the transmission mechanism. The raised portion is inserted and fixed in the second through hole, and the fixed portion abuts and is fixed to the side of the first cover facing the base. The insertion of the raised portion in the second through hole and the abutment of the fixed portion with the first cover both serve as assembly positioning functions, facilitating assembly. Furthermore, this provides a larger contact area between the first cover and the second cover, resulting in higher reliability.

[0037] In one possible implementation, the rotating member further includes a transmission portion secured to the main body, a transmission mechanism cooperating with the transmission portion, and the transmission mechanism drives the rotating member to rotate via the transmission portion. The base includes a retaining groove within which the transmission portion is located. The retaining groove acts as a limiter, ensuring reliable rotation of the rotating member within the base. Furthermore, the retaining groove design allows the rotating member to define a rotational arc, thereby adjusting the lifting height of the lifting member to meet varying requirements.

[0038] Buffer pads are provided at both ends of the limit slot along the rotational direction of the rotating member, with the buffer pads at least partially protruding from the limit slot. When the transmission part rotates to either end of the limit slot, it can contact the buffer pads, providing a cushioning effect, reducing or avoiding abnormal noise caused by the transmission part directly colliding with the end (base) of the limit slot, thereby improving the user experience.

[0039] In one possible implementation, multiple weight-reducing grooves are provided on the transmission unit. This reduces the weight of the transmission unit and the entire rotating component, lowering the moment of inertia. This in turn reduces or prevents damage to the transmission unit caused by collisions between the transmission unit and the base due to the moment of inertia. Furthermore, the rotational impact force on the gear assembly (transmission mechanism) caused by the transmission unit's own weight during a fall or other event can be reduced, thereby protecting the transmission mechanism.

[0040] In one possible implementation, the transmission part has a second slider, the base has an arc-shaped second slide rail, the second slide rail is located in the limiting groove, the second slider slides along the second slide rail, and the rotation of the rotating part is further limited by the cooperation of the second slide rail and the second slider, thereby ensuring the rotation stability of the rotating part.

[0041] The base has a second groove on the side facing the rotating member, and the second groove is used to accommodate a lubricating structure. The lubricating structure can play a lubricating role, for example, to improve the smoothness of the rotation of the rotating member and improve the shaking and abnormal noise between the rotating member and the base.

[0042] In a possible implementation, a surface of the cover plate facing the base has a raised limiting member, and at least the main body of the rotating member is located between the limiting member and the base.

[0043] A third groove is provided on a surface of the main body facing the cover plate, and the third groove is used to accommodate the lubrication structure.

[0044] In one possible implementation, the drive mechanism has a drive portion and an output shaft. The output shaft cooperates with the transmission mechanism. The drive portion is used to rotate the output shaft. The rotation of the output shaft drives the rotating member to rotate through the transmission mechanism. At least part of the output shaft is located in the accommodating cavity.

[0045] There is a raised stopper on the base, which is located in the accommodating cavity and on the side of the output shaft along the rotation axis facing away from the driving part. The stopper can limit the output shaft and restrict the movement of the output shaft along the axis, thereby improving the abnormal sound and noise problems of the driving mechanism.

[0046] In one possible implementation, the distance between the side of the stopper facing the output shaft and the end face of the output shaft facing away from the driving part along the rotation axis is 0.1 mm to 0.2 mm, so as to avoid limiting the displacement of the output shaft under the condition that the stopper affects the rotation of the output shaft, so that the displacement of the output shaft will not hit the internal structure of the driving part and cause abnormal noise and other problems as much as possible.

[0047] In one possible implementation, the base includes a bottom wall and side walls, the side walls being disposed around the bottom wall, and the cover being fixed to the side walls. A third rail is provided on the side wall, and a third slider is provided on the lifting member. The third rail extends in the thickness direction, and the third slider slides along the third rail. The guiding function of the third rail ensures that the lifting member, driven by the rotating member, can move up and down in the thickness direction.

[0048] In one possible implementation, there are multiple third sliders, and the multiple third sliders are evenly distributed around the circumference of the lifting member. Multiple evenly distributed third sliders can provide uniform support for the lifting member, which can improve problems such as pressing hollow and pressing shaking.

[0049] In one possible implementation, a waterproof breathable member is further provided on the base, and the inside and outside of the base are connected through the waterproof breathable member. The waterproof breathable member allows gas to pass through but not liquid, meeting the ventilation requirements of the camera module and ensuring the waterproof performance of the camera module.

[0050] In one possible implementation, the lifting device further includes a top protective cover, which is disposed on an end of the lifting member facing away from the rotating member. The top protective cover protects structural components located on the side of the top protective cover facing the base, such as the lifting member and the camera assembly.

[0051] In one possible implementation, the end of the lifting member facing away from the rotating member is sleeved in the top protective cover, and an adhesive layer is provided between the outer wall of the end of the lifting member facing away from the rotating member and the inner wall of the top protective cover, so that the lifting member is fixed to the top protective cover through the adhesive layer.

[0052] A fourth groove is defined on the outer wall of the end of the lifting member facing away from the rotating member, and a fifth groove is defined on the inner wall of the top protective cover. The adhesive layer fills these two grooves. These grooves increase the bonding area between the lifting member and the top protective cover, enhancing adhesion. Furthermore, the adhesive layer within these two grooves forms an undercut structure, further enhancing adhesion and preventing the top protective cover from falling off in the event of a fall.

[0053] A second aspect of an embodiment of the present application provides a camera module, comprising a camera device and any of the above-mentioned lifting devices, wherein the camera device is arranged in the lifting device, and at least a portion of the camera device can be moved along the thickness direction.

[0054] A third aspect of an embodiment of the present application provides an electronic device, comprising a housing and the above-mentioned camera module, wherein the camera module is at least partially located in the housing. BRIEF DESCRIPTION OF THE DRAWINGS

The interface may also be used to implement data transmission between the electronic device 100 and an external device, for example, it may also be used to connect headphones, a projection device, etc.

[0101] The electronic device 100 may further include a charging management module and a power management module (not shown in the figure), and the charging management module and the power management module may also be fixed in the above-mentioned accommodation space.

[0102] The charging management module is configured to receive charging input from a charger. The charger can be either a wireless charger or a wired charger. In some wired charging examples, the charging management module can receive charging input from the wired charger via an interface. In some wireless charging embodiments, the charging management module can receive wireless charging input via a wireless charging coil of the electronic device 100. The charging management module can charge the battery 106 and also provide power to the electronic device 100 through the power management module.

[0103] The power management module is used to connect the battery 106, the charging management module, and the processor. The power management module receives input from the battery 106 and / or the charging management module to power the processor, memory, display 104, camera module 107, etc. The power management module can also be used to monitor parameters such as the battery 106 capacity, battery 106 cycle count, and battery 106 health status (leakage, impedance).

[0104] In some examples, the power management module may be provided in a processor of the main circuit board 105. In other examples, the power management module and the charging management module may also be provided in the same device.

[0105] 3 , the middle frame 102 may include a middle plate 1021 and a frame 1022. The frame 1022 may be disposed around the outer periphery of the middle plate 1021 and may be in an annular structure.

[0106] The material of the middle plate 1021 can be aluminum, aluminum alloy, or magnesium alloy, and there is no limitation on the material of the middle plate 1021. The frame 1022 can be a metal frame or a ceramic frame, and there is no limitation on the material of the frame 1022.

[0107] It should be noted that the middle plate 1021 and the frame 1022 can be formed separately, and the middle plate 1021 and the frame 1022 can be fixed together by welding, clamping, bonding, etc. Alternatively, the middle plate 1021 and the frame 1022 can also be formed in one piece.

[0108] Alternatively, in some other examples, the middle frame 102 may not include the middle plate 1021, and the middle frame 102 may have a ring structure. For example, the middle frame 102 and the back cover 103 may be formed separately, and the middle frame 102 and the back cover 103 may be fixed together by welding, clamping, bonding, etc. Alternatively, the middle frame 102 and the back cover 103 may be formed integrally.

[0109] 2 and 3 , the electronic device 100 may further include a camera module 107 . The camera module 107 is used to implement functions such as photographing, and the camera module 107 may also be disposed in the aforementioned accommodation space.

[0110] The number of camera modules 107 may be one, or the number of camera modules 107 may be multiple to meet different shooting requirements.

[0111] For example, the camera module 107 can be a rear-facing camera, for example, the light inlet of the camera module 107 can face the exterior surface of the back cover 103 (the side facing away from the display screen 104). Alternatively, the camera module 107 can be a front-facing camera, for example, the light inlet of the camera module 107 can face the display surface of the display screen 104 (the side facing away from the back cover 103).

[0112] As shown in Figure 3, taking the camera module 107 as a rear-facing camera, the camera module 107 can be positioned on the side of the mid-plate 1021 facing the back cover 103, with an opening 1031 defined in the back cover 103. The camera module 107 can be completely located within the housing space, allowing light to enter the camera module 107 through the opening 1031 in the back cover 103, thus satisfying the camera module 107's image capture requirements. Alternatively, the camera module 107 can be partially located within the housing space, with the camera module 107 partially protruding through the opening 1031 on the side of the back cover 103 facing away from the display screen 104, thereby facilitating a thinner design for the electronic device 100.

[0113] The structures illustrated in the embodiments of this application do not constitute specific limitations on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or may have different component arrangements. For example, the electronic device 100 may also include a communication module, a sensor, a microphone, a speaker, a flash, and other devices.

[0114] With the development of camera modules on electronic devices, the optical functions of camera modules have become more powerful and the size of camera modules has become larger. In order to meet the thinning of electronic devices, the camera modules protrude more seriously on the appearance of electronic devices, thereby affecting the exquisite appearance of electronic devices.

[0115] Therefore, the camera module can be set as a liftable structure. For example, the camera module can include a lifting device and a camera device. The lifting device can have an extended state and a retracted state. Part of the lifting device can be lifted and moved along the thickness direction to realize the switching of the lifting device between the extended state and the retracted state.

[0116] The camera assembly is disposed within the lifting device, and at least a portion of the camera assembly is movable within the lifting device. For example, the camera assembly may include multiple lenses, at least a portion of which is movable. For example, all of the multiple lenses of the camera assembly may be movable, or at least a portion of the multiple lenses adjacent to the object side may be movable, to adjust the optical distance between the lenses, thereby adjusting optical properties of the camera assembly, such as focal length, to achieve high-quality imaging.

[0117] The number of lenses may be a positive integer greater than or equal to 2, and the molding material of the lenses may include plastic, glass, etc.

[0118] When the camera module is capturing images, the lifting mechanism can be extended, increasing the internal space of the lifting mechanism and providing the camera with a larger optical space. For example, the camera lens has more room to move, meeting the requirements of high-quality image capture. When the camera module is not capturing images, the lifting mechanism can be retracted, making the camera module smaller, meeting the requirements of the electronic device's thinning design, and minimizing the impact on the electronic device's appearance.

[0119] FIG4 is a schematic structural diagram of a lifting device in a camera module provided in the present application in a retracted state.

[0120] For example, as shown in FIG4 , the lifting device 10 may include a base 11 and a cover 12 , wherein the base 11 may have a receiving cavity (not shown in the figure), and the camera device may be accommodated in the receiving cavity of the base 11 . The cover 12 may be provided on the base 11 .

[0121] FIG5 is a schematic diagram of the disassembled structure of the lifting device in FIG4 .

[0122] As shown in Figure 5, the lifting device 10 may include a lifting member 14 and a rotating member 13. The rotating member 13 can be rotatably set in the accommodating cavity 11a of the base 11. For example, the accommodating cavity 11a of the base 11 can define a space for the rotating member 13 to rotate. The rotating member 13 can be sleeved in the base 11 and rotatably set relative to the base 11.

[0123] Exemplarily, the rotating member 13 may be an annular structure, such as a ring-shaped structure. The rotating member 13 has an avoidance hole 136 inside to avoid movement of the camera device.

[0124] The lifting member 14 can be located on the side of the rotating member 13 facing the cover 12. The rotating member 13 and at least a portion of the lifting member 14 can be located within the accommodating cavity 11a of the base 11 (see FIG6 ). For example, the lifting member 14 can also be an annular structure, for example, a ring-shaped structure. The lifting member 14 also has an escape hole 145 inside to prevent movement of the camera assembly.

[0125] A linkage member 17 is provided on one of the rotating member 13 and the lifting member 14. The linkage member 17 cooperates with the other of the rotating member 13 and the lifting member 14. For example, the linkage member 17 can be linked with the other of the rotating member 13 and the lifting member 14 by means of a guide rail. As shown in FIG5 , the linkage member 17 can be assembled on the rotating member 13. The linkage member 17 can have a first slider 171. The lifting member 14 can have a first slide rail 141 that is inclined in the thickness direction. The first slider 171 can be placed in the first slide rail 141 and slide along the first slide rail 141 (see FIG11 ). During the rotation of the rotating member 13, the linkage member 17 can be driven to rotate. The first slider 171 of the linkage member 17 slides along the inclined first slide rail 141, thereby causing the lifting member 14 to move toward or away from the rotating member 13 in the thickness direction, thereby switching the lifting device 10 between the extended state and the retracted state.

[0126] The cover plate 12 may also be provided with an avoidance hole 126 to avoid movement of the lifting member 14 and the camera device.

[0127] Continuing with FIG5 , the lifting device 10 may further include a top protective cover 15. The top protective cover 15 is disposed on the end of the lifting member 14 facing away from the rotating member 13. When the lifting member 14 moves in the thickness direction, the top protective cover 15 is driven to move in the thickness direction. The top protective cover 15 protects structural components located on the side of the top protective cover 15 facing the base 11, such as the lifting member 14 and the camera assembly.

[0128] Among them, the top protective cover 15 can be located on the side of the cover plate 12 facing away from the base 11, or, in some examples, the top protective cover 15 can also be partially located in the accommodating cavity 11a surrounded by the cover plate 12 and the base 11, and the top protective cover 15 can be raised and lowered through the avoidance hole on the cover plate 12.

[0129] The top protective cover 15 may include a light-transmitting portion 151 and a surrounding portion 152 . The surrounding portion 152 is arranged around the outer periphery of the light-transmitting portion 151 . The light-transmitting portion 151 allows light to pass through into the lifting device 10 and then into the camera device to meet the shooting requirements of the camera device.

[0130] For example, when the camera module is assembled in an electronic device, at least a portion of the top protective cover 15 may protrude outside the back cover of the electronic device.

[0131] The lifting device 10 may further include a side protective cover 16, which may surround the outer periphery of the end of the lifting member 14 facing away from the rotating member 13 (as shown in FIG6 ). The side protective cover 16 may protect the structural components located inside the side protective cover 16, such as the lifting member 14.

[0132] For example, one end of the side protective cover 16 can be fixed to the cover plate 12, and the other end of the side protective cover 16 can be fixed to the end of the lifting member 14 facing away from the rotating member 13. The other end of the side protective cover 16 can move with the lifting and lowering movement of the lifting member 14. For example, the side protective cover 16 can be a flexible structural member, such as a rubber member, so that the side protective cover 16 can be deformed to ensure that the other end of the side protective cover 16 can move with the lifting and lowering movement of the lifting member 14. This structure is simple and easy to implement.

[0133] Of course, in some examples, the side protective cover 16 may also be a telescopic member that telescopes as the lifting member 14 moves upward and downward.

[0134] In some examples, the lifting device 10 may further include a bottom protective plate (not shown), which may be fixed to the side of the base 11 facing away from the cover plate 12. For example, the bottom protective plate and the cover plate 12 may be located on opposite sides of the base 11 in the thickness direction. The camera device may be mounted on the bottom protective plate.

[0135] FIG6 is a schematic cross-sectional view of the lifting device in FIG4 .

[0136] As shown in FIG6 , for example, the rotating member 13 can be nested within the base 11, and the lifting member 14 and the rotating member 13 can have an overlapping region in the thickness direction, thereby reducing the overall thickness of the rotating member 13 and the lifting member 14. For example, the rotating member 13 and the lifting member 14 can at least partially nest within each other, such as at least a portion of the lifting member 14 can nest within at least a portion of the outside of the rotating member 13. Alternatively, at least a portion of the rotating member 13 can nest within at least a portion of the outside of the lifting member 14.

[0137] In the thickness direction, there may also be an overlapping area between the lifting member 14 and the base 11. For example, part of the lifting member 14 may be sleeved inside the base 11, and part of the lifting member 14 may pass through the avoidance hole of the cover 12 and protrude outside the accommodating cavity 11a of the base 11.

[0138] Of course, in some examples, the rotating member 13 (base 11 ) and the lifting member 14 may be spaced apart in the thickness direction to avoid mutual interference between the rotating member 13 and the lifting member 14 during assembly.

[0139] The linkage member 17 can be provided on the lifting member 14, and the linkage member 17 cooperates with the rotating member 13, so that when the rotating member 13 rotates, the linkage member 17 drives the lifting member 14 to move through the linkage member 17. Alternatively, the linkage member 17 can be provided on the rotating member 13 (as shown in conjunction with FIG5 ), and the linkage member 17 cooperates with the lifting member 14. In the embodiment of the present application, the retracted state and the extended state of the lifting device 10 are described by taking the case where the linkage member 17 is provided on the rotating member 13 and the linkage member 17 cooperates with the lifting member 14 to drive the lifting member 14 to move up and down along the thickness direction as an example.

[0140] A linkage member 17 is provided on the rotating member 13, and the rotating member 13 cooperates with the lifting member 14 through the linkage member 17. Referring to Figure 6, when the lifting device 10 is in a retracted state, the larger part of the lifting member 14 can be located in the accommodating cavity 11a of the base 11, and the smaller part of the lifting member 14 can be located outside the accommodating cavity 11a. The part of the lifting member 14 extending outside the accommodating cavity 11a has a smaller spatial gain in the thickness direction. At this time, the thickness of the lifting device 10 is smaller, which is conducive to the thinning of the electronic device, and the thickness of the entire camera module is relatively small, and the thickness of the camera module protruding from the electronic device is also smaller, reducing the impact on the appearance of the electronic device.

[0141] It should be noted that when the lifting device 10 is in a retracted state, the camera device can also be in a retracted state, that is, the distance between the movable lenses in the camera device is relatively close, so that the thickness of the camera device is smaller, ensuring that the camera device is accommodated in the lifting device 10 and will not affect the retraction of the lifting device 10.

[0142] By driving the rotating member 13 to rotate (such as rotating the rotating member 13 counterclockwise), the rotating member 13 drives the linkage member 17 to rotate, and the linkage member 17 drives the lifting member 14 to move along the thickness direction (such as the z direction in the figure). If the lifting member 14 moves away from the rotating member 13 along the thickness direction, the lifting member 14 and the top protective cover 15 rise along the thickness direction relative to the base 11 (accommodating chamber 11a), the cover plate 12, etc., and finally the lifting device 10 can be in an extended state.

[0143] FIG7 is a schematic cross-sectional view of the lifting device in FIG4 when it is in an extended state.

[0144] As shown in Figure 7, when the lifting device 10 is in the extended state, the smaller part of the lifting member 14 can be located in the accommodating cavity 11a of the base 11, and the larger part of the lifting member 14 can protrude outside the accommodating cavity 11a of the base 11. The part of the lifting member 14 extending outside the accommodating cavity 11a has a larger spatial gain in the thickness direction, which increases the thickness of the lifting device 10. At this time, the thickness of the lifting device 10 is larger, and the internal optically available space is larger, that is, the available moving space for the camera device is larger, and better shooting quality can be obtained.

[0145] Correspondingly, when the lifting device 10 is in the extended state, by driving the rotating member 13 to rotate (such as rotating the rotating member 13 clockwise), the rotating member 13 drives the linkage member 17 to rotate, and the linkage member 17 drives the lifting member 14 to move along the thickness direction. For example, the lifting member 14 moves toward the rotating member 13 along the thickness direction, and the lifting member 14 and the top protective cover 15 descend along the thickness direction relative to the base 11 (accommodating chamber 11a), the cover plate 12, etc., so that the lifting device 10 can finally be in the retracted state.

[0146] It should be noted that the lifting device 10 can also be in an intermediate state between the extended state and the retracted state, that is, through the coordinated movement between the rotating part 13, the linkage part 17 and the lifting part 14, the lifting device 10 can be switched between the extended state and the retracted state.

[0147] In the related art, a linkage member is typically fixed to one of the rotating member and the lifting member, and the linkage member cooperates with the other. For example, the first end of the linkage member can be fixed to the rotating member by bonding, welding, or integral molding. The second end of the linkage member can cooperate with the lifting member. For example, the second end of the linkage member can have a slider, and the lifting member can have a slide rail inclined in the thickness direction. The slider can be placed on the slide rail and slide along the slide rail. When the rotating member rotates, it drives the linkage member to rotate, and the slider on the linkage member slides along the inclined slide rail, thereby causing the lifting member to move up and down in the thickness direction.

[0148] However, in scenarios such as falling and pressing, the impact force acting on the camera module will first act on the top protective cover and be transmitted by the top protective cover to the lifting parts, linkage parts and rotating parts. The lifting parts, linkage parts and rotating parts are structural components that move, with light weight and relatively weak strength, and are prone to problems such as yield deformation or breakage, causing damage to the camera module and electronic equipment.

[0149] FIG8 is a front view structural diagram of the cooperation between the rotating member and the lifting member when the lifting device of FIG6 is in a retracted state.

[0150] In an embodiment of the present application, as shown in Figure 8, the lifting device includes an elastic member 18, and the elastic member 18 is provided on one of the rotating member 13 and the lifting member 14 equipped with the linkage member 17. For example, taking the linkage member 17 provided on the rotating member 13 as an example, the rotating member 13 is also provided with an elastic member 18, and the elastic member 18 is located between the linkage member 17 and the rotating member 13. The elastic expansion and contraction of the elastic member 18 is used to achieve buffering of the impact force, reduce or avoid damage to weak components such as the rotating member, the lifting member and the linkage member, and improve the stability and reliability of the camera module and the electronic equipment.

[0151] For example, when the elastic member 18 is placed between the linkage member 17 and the rotating member 13, the elastic member 18 can maintain a compressed state. As long as the camera module is impacted by external force in the thickness direction, the elastic member 18 can play a buffering role, thereby achieving full-process buffering and better protecting the camera module.

[0152] It is understood that when the elastic member 18 is positioned between the linkage member 17 and the rotating member 13, the elastic member 18 remains compressed. The resilience of the compressed elastic member 18 provides excellent support for the linkage member 17 and the lifting member 14. This ensures a stable assembly relationship between the linkage member 17 and the rotating member 13 when not subject to external force. Furthermore, when the rotating member 13 rotates to drive the lifting member 14 upward and downward, the lifting member 14 can be lifted and lowered with precision and smoothness along the thickness direction. That is, when not subject to external force, rotating the rotating member 13 can achieve the lifting and lowering movement of the lifting member 14, switching the lifting device between the extended and retracted states, while the elastic member 18 remains in its current compressed state. When subject to external force, the elastic member 18 elastically expands and contracts to provide cushioning, preventing the rotating member 13 from rotating and maintaining the extended and retracted states of the lifting device.

[0153] Of course, in some examples, the elastic member 18 is placed between the linkage member 17 and the rotating member 13. When not impacted by external force, the elastic member 18 may also be in a natural state, neither compressed nor stretched.

[0154] Exemplarily, the linkage member 17 can be assembled on the rotating member 13, and the linkage member 17 can have a protruding first slider 171 (refer to Figure 5) on the end facing away from the rotating member 13. The lifting member 14 can have a first slide rail 141, and the first slider 171 can be inserted into the first slide rail 141 and slide along the first slide rail 141.

[0155] The first slide rail 141 can extend radially through the outer and inner walls of the rotating member 13 of the lifting member 14. Alternatively, the first slide rail 141 can be formed by a groove provided on the outer or inner wall of the lifting member 14. The first slider on the linkage member 17 can be located inside the lifting member 14, and inserted into the first slide rail 141 from the inside of the lifting member 14. Alternatively, as shown in FIG8 , the first slider on the linkage member 17 can be located outside the lifting member 14, and inserted into the first slide rail 141 from the outside of the lifting member 14.

[0156] It is understandable that, in some possible examples, the linkage member 17 may also be provided with a first slide rail 141 , and the lifting member 14 may be provided with a first slider 171 .

[0157] Among them, the first slide rail 141 is at least partially inclined. For example, as shown in Figure 8, the first slide rail 141 may include a first end 1411, a second end 1413 and an inclined section 1412 located between the first end 1411 and the second end 1413 (as shown in Figure 13). The inclined section 1412 is inclined relative to the thickness direction (z direction), so that when the first slider and the linkage member 17 slide along the inclined section 1412, they can apply a force in the thickness direction relative to the lifting member 14, causing the lifting member 14 to move up and down along the thickness direction.

[0158] Exemplarily, the first end 1411 can be arranged closer to the main body 131 of the rotating member 13, and the second end 1413 can be arranged farther away from the main body 131 of the rotating member 13. The inclined section 1412 connects the first end 1411 and the second end 1413, that is, in the direction from the first end 1411 to the second end 1413, the inclined section 1412 can be inclined in the direction away from the main body 131 of the rotating member 13.

[0159] When the first sliding block of the linkage member 17 is located at the second end portion 1413 of the first slide rail 141 , the lifting device 10 may be in a retracted state.

[0160] FIG9 is another front cross-sectional view of the lifting device in FIG6 in a retracted state.

[0161] When the lifting device 10 is in the retracted state, in scenarios such as falling or pressing, the camera module is subjected to external force impact, which generally includes a force downward in the thickness direction, such as the external force F in the figure. As shown in Figure 10, the external force F first acts on the top protective cover 15, and the top protective cover 15 moves downward, and the top protective cover 15 transmits the external force F to the lifting member 14. In combination with Figure 8, the external force F is transmitted to the linkage member 17, the elastic member 18 and the rotating member 13 via the lifting member 14. The elastic member 18 can be compressed, thereby buffering the external force F through the elastic member. In the process of buffering the impact external force, the first slider of the linkage member 17 remains at the second end 1413.

[0162] The rotating member 13 is driven to rotate, and the rotating member 13 drives the linkage member 17 to rotate. The first slider 171 of the linkage member 17 slides along the first slide rail 141 toward the inclined section 1412 and the first end 1411 (refer to Figure 8), thereby pushing the lifting member 14 to move along the thickness direction (z direction).

[0163] FIG10 is a front view structural diagram of the cooperation between the rotating member and the lifting member when the lifting device of FIG7 is in the extended state.

[0164] 10 , when the first slider of the linkage member 17 on the rotating member 13 is located at the first end 1411 , the lifting device 10 may be in an extended state.

[0165] FIG11 is another front view of the cross-sectional structure of the lifting device in FIG7 in the extended state.

[0166] Accordingly, when the lifting device 10 is in the extended state, as shown in FIG11 , in scenarios such as falling or pressing, an external force F acts on the top protective cover 15, causing it to move downward, transmitting the external force F to the lifting member 14. As shown in FIG10 , the external force F is transmitted via the lifting member 14 to the linkage member 17, the elastic member 18, and the rotating member 13. The elastic member 18 is compressed, thereby buffering the external force F. During this process of buffering the impact force, the first slider of the linkage member 17 remains at the first end 1411.

[0167] Of course, in some examples, the linkage member 17 can also be assembled on the lifting member 14. The linkage member 17 can have a protruding first slider 171 on the end facing away from the lifting member 14, and a first slide rail 141 can be provided on the rotating member 13. The first slider 171 can be inserted into the first slide rail 141 and slide along the first slide rail 141, which can also realize the linkage of the rotating member 13 rotating and driving the lifting member 14 to move up and down through the linkage member 17.

[0168] FIG12 is an assembly diagram of the rotating member, the lifting member and the linkage member in the lifting device of FIG6 .

[0169] As shown in Figure 12, the lifting device 10 also includes at least two guide members 19, and the linkage member 17 is located on the at least two guide members 19. The at least two guide members 19 are used to guide the sliding of the linkage member 17. In scenarios where buffering is achieved by falling, pressing, etc., the linkage member 17 can slide along the thickness direction.

[0170] For example, the guide member 19 can be a cylindrical guide structure, and the extension direction of the guide member 19 can be consistent with the thickness direction. The linkage member 17 can be mounted on the outside of at least two guide members 19, so that the linkage member 17 can slide up and down along the extension direction of the guide members 19. In other words, the movement direction of the linkage member 17 is limited by the guide member 19, so that the linkage member 17 slides along the thickness direction. This ensures that in scenarios where buffering is achieved, such as falling or pressing, the linkage member 17 only slides along the thickness direction, and does not tilt or rotate forward and backward (along the radial direction of rotation of the rotating member 13) or left and right (along the tangential direction of rotation of the rotating member 13). This improves the smoothness of buffering under impact and avoids buffering jams, buffering failure, and other problems caused by scratches between the linkage member 17 and the rotating member 13.

[0171] It can be understood that there are at least two guide members 19. For example, at least two guide members 19 can be arranged at intervals in the circumferential direction of the rotating member 13. The limiting effect of at least two guide members 19 on the linkage member 17 can prevent the linkage member 17 from rotating around the guide member 19, further ensuring that the linkage member 17 moves along the thickness direction under the action of the guide member 19, and is also conducive to avoiding problems such as buffer failure and buffer jamming.

[0172] The elastic member 18 can be located on at least one of the at least two guide members 19. For example, referring to Figure 12, taking the number of guide members 19 as three as an example, for example, the first guide member 191, the second guide member 192 and the third guide member 193, the linkage member 17 can be mounted on at least one of the first guide member 191, the second guide member 192 and the third guide member 193, such as the elastic member 18 can be provided on the second guide member 192 and the third guide member 193, and the elastic member 18 is located between the linkage member 17 and the rotating member 13.

[0173] It should be noted that the elastic member 18 can be located on any one or more of the first guide member 191, the second guide member 192, and the third guide member 193. For example, the elastic member 18 can be provided on one of the first guide member 191, the second guide member 192, and the third guide member 193. Alternatively, the elastic member 18 can be provided on each of the first guide member 191, the second guide member 192, and the third guide member 193. Alternatively, the elastic member 18 can be provided on both the first guide member 191 and the second guide member 192, or on both the first guide member 191 and the third guide member 193.

[0174] The guide member 19 provided with the elastic member 18 can also guide the expansion and contraction of the elastic member 18. In scenarios where cushioning is achieved, such as falling or pressing, the elastic member 18 can be caused to expand and contract in the thickness direction. For example, the elastic member 18 can be mounted on the guide member 19 extending in the thickness direction, so that the elastic member 18 expands and contracts in the thickness direction under the guidance of the guide member 19. This helps ensure smooth movement of the linkage member 17 in the thickness direction during elastic cushioning and also helps improve the smoothness of cushioning under impact.

[0175] The following description will assume that the linkage member 17 is located on the rotating member 13 to describe the assembly method of the linkage member 17 .

[0176] FIG13 is a schematic diagram of the disassembled structure of the rotating member and the lifting member in FIG10 .

[0177] As shown in FIG. 13 , the rotating member 13 includes a main body 131 and a mounting portion 132 . The main body 131 may be an annular structure, and has an escape hole 136 therein for evading the camera device.

[0178] The mounting portion 132 is fixed to the main body 131. An accommodating space 133 is defined between the main body 131 and the mounting portion 132. The linkage member 17 is at least partially disposed within the accommodating space 133. For example, the linkage member 17 may be partially located within the accommodating space 133 and partially extend outside the accommodating space 133 to facilitate insertion and engagement with the first slide rail 141 of the lifting member 14. The elastic member 18 is also located within the accommodating space 133, between the linkage member 17 and the main body 131. Correspondingly, the guide member 19 is also located within the accommodating space 133.

[0179] Among them, the first slide rail 141 of the lifting member 14 can also include a notch 1414, the notch 1414 can be connected to the second end 1413, and the notch 1414 can extend to the side of the lifting member 14 facing the rotating member 13, so that during assembly, the first slider 171 of the linkage member 17 can be inserted into the first slide rail 141 through the notch 1414.

[0180] Exemplarily, the mounting portion 132 can be fixed to the main body 131 by welding or bonding, but in buffering scenarios such as falling and pressing, when external force acts on the linkage member 17 and the elastic member 18 and causes the elastic member 18 to contract, the rebound force of the elastic member 18 reacts on the linkage member 17, such as pushing the linkage member 17 upward in the thickness direction (backwards from the main body 131), and the linkage member 17 acts on the mounting portion 132, which can easily cause the mounting portion 132 to fall off and separate from the main body 131, resulting in low assembly stability of the linkage member 17, the elastic member 18, etc., and prone to buffering failure and other problems.

[0181] In the embodiment of the present application, the main body 131 and the mounting portion 132 can be integrally formed, that is, the rotating member 13 formed by the main body 131 and the mounting portion 132 is an integral structural member, and the mounting portion 132 and the main body 131 have a high degree of bonding strength. The linkage member 17 is arranged in the accommodating space 133 enclosed by the mounting portion 132 and the main body 131, which can significantly improve the assembly strength of the elastic member 18 and the linkage member 17 on the rotating member 13. This reduces or avoids damage to the mounting portion 132 (the top wall of the mounting portion 132) caused by the rebound action of the elastic member 18, further avoids the problem of buffer failure, and improves the reliability of resisting impact forces in buffering scenarios such as falling and pressing.

[0182] Among them, a plurality of mounting portions 132 can be provided on the rotating member 13, and each mounting portion 132 can enclose a receiving space 133 with the main body portion 131, and the above-mentioned linkage member 17, an elastic member 18 and at least two guide members 19 are provided in the receiving space 133.

[0183] For example, four mounting portions 132 can be provided on the rotating member 13 to form four accommodating spaces 133. The four mounting portions 132 can be evenly arranged on the circumference of the main body 131, which is beneficial to improving the smoothness of the rotating member 13 driving the lifting member 14 to rise and fall along the thickness direction, and is also beneficial to improving the buffering smoothness in scenarios such as falling and pressing.

[0184] Taking the example of each accommodating space 133 having one linkage part 17, three guide parts 19 and two elastic parts 18, there are a total of 4 linkage parts 17, 12 guide parts 19 and 8 elastic parts 18 on the rotating part 13, which can achieve effective buffering and provide stable guiding effect during the buffering process, thereby improving the smoothness of the buffering.

[0185] Of course, in some other examples, the number of the mounting portions 132 may also be two or more other positive integers, and the plurality of mounting portions 132 may be evenly arranged along the circumference of the main body 131 .

[0186] It can be understood that when the linkage part 17 is set on the lifting part 14, the lifting part 14 can also include an integrally formed mounting portion 132 and a main body portion 131. The main body portion 131 can also be a ring structure with an avoidance hole inside for avoiding the camera device. The mounting portion 132 and the main body portion 131 form an accommodating space 133, and the linkage part 17, the elastic part 18, and the guide part 19 are located in the accommodating space 133.

[0187] FIG14 is a schematic diagram showing the partial structural breakdown of the rotating member in FIG13 .

[0188] Since the mounting portion 132 and the main body 131 are integrally formed, in order to facilitate the assembly of the guide member 19, the elastic member 18 and the linkage member 17, a first through hole can be opened on at least one of the mounting portion 132 and the main body 131. The guide member 19 can pass through the first through hole and be fixed in the first through hole, so that the guide member 19 can be fixed in the accommodating space 133 surrounded by the mounting portion 132 and the main body 131. The guide member 19 can be fixed to the main body 131 and the mounting portion 132 respectively, so that the linkage member 17, the elastic member 18 and the guide member 19 are all arranged in the accommodating space 133.

[0189] The guide member 19 is assembled and fixed by the first through hole on at least one of the mounting portion 132 and the main body portion 131. The assembly operation is simple and easy to install, and can be achieved without the need for additional assembly parts. This is beneficial to reducing component structure and cost, and will not occupy space in the thickness direction, which is beneficial to the thinning design of the lifting device.

[0190] Exemplarily, the guide member 19 can be a guide column, and the inner diameter of the first through hole can be larger than the outer diameter of the guide member 19, so that the guide member 19 can pass through the first through hole into the accommodating space 133, thereby achieving the fixation of the guide member 19 to the mounting part 132 and the main body 131.

[0191] For example, referring to FIG14 , taking the first guide member 191 as an example, a first through hole 134a may be defined in the main body 131, and a first through hole 134b may be defined in the mounting portion 132. During actual assembly, the linkage member 17 and the elastic member 18 may be placed within the accommodating space 133, so that the first end of the first guide member 191 can pass through the first through hole 134a into the accommodating space 133 and pass through the linkage member 17 into the first through hole 134b. At this point, the second end of the first guide member 191 can be located within the first through hole 134a. The first end outer wall of the first guide member 191 can be fixed to the inner wall of the first through hole 134b, and the second end outer wall of the first guide member 191 can be fixed to the inner wall of the first through hole 134a, by welding, bonding, or clamping. This achieves the secure assembly of the first guide member 191 and the linkage member 17 within the accommodating space 133.

[0192] Correspondingly, the second guide member 192 and the third guide member 193 can also be secured in the same manner. For example, the first end of the second guide member 192 can pass through the first through-hole 134c of the main body 131 to enter the accommodating space 133, pass through the elastic member 18 and the linkage member 17, and be inserted into the first through-hole 134d of the mounting portion 132. The second end of the second guide member 192 is positioned within the first through-hole 134c of the main body 131. The first end of the second guide member 192 is secured to the first through-hole 134c of the mounting portion 132, and the second end of the second guide member 192 is secured to the first through-hole 134d of the main body 131, thereby securing the second guide member 192, the linkage member 17, and the elastic member 18 within the accommodating space 133.

[0193] For example, the first end of the third guide member 193 can pass through the first through hole 134e on the main body 131 to enter the accommodating space 133, and pass through the elastic member 18, the linkage member 17, and the first through hole 134f on the insertion mounting portion 132. The second end of the third guide member 193 is located in the first through hole 134e on the main body 131. The first end of the third guide member 193 is fixed to the first through hole 134f on the mounting portion 132, and the second end of the third guide member 193 is fixed to the first through hole 134e on the main body 131, respectively, to achieve fixed assembly of the third guide member 193, the linkage member 17 and the elastic member 18 in the accommodating space 133.

[0194] For example, referring to Figure 14 , the mounting portion 132 may include a top wall 1321 and two extension walls 1322. The top wall 1321 may be opposite to the main body 131. Both ends of the top wall 1321 are respectively connected to the main body 131 through the extension walls 1322. The top wall 1321, the extension walls 1322 and the main body 131 form a receiving space 133.

[0195] First through holes may be provided on both the top wall 1321 and the main body 131. For example, the top wall 1321 may have first through holes 134b, 134d, and 134f, respectively, while the main body 131 may have first through holes 134a, 134c, and 134e, respectively. This allows the ends of the guide member 19 to be inserted and fixed to the top wall 1321 and the main body 131, respectively.

[0196] In which, a first groove 1323 can be opened on the side of the top wall 1321 facing away from the main body 131, and the above-mentioned first through hole can be opened on the bottom wall of the first groove 1323, such as the first through hole 134b, the first through hole 134d and the first through hole 134f can be opened on the bottom wall 111 of the first groove 1323.

[0197] The lifting device may further include a first connecting member (not shown), through which one end of the guide member 19 may be fixed within the first through hole 134. For example, the first connecting member may be a welding member, an adhesive member, a clamping member, etc., so that the guide member 19 is fixed to the mounting portion 132 and the main body 131 by welding, bonding, or clamping.

[0198] The first connector can be located in the first groove 1323, which can facilitate positioning during assembly. On the other hand, the recessed first groove 1323 can free up space along the thickness direction, allowing the first connector to be fixed in the first groove 1323, thereby reducing or avoiding the space occupied by the first connector in the thickness direction.

[0199] Exemplarily, the main body 131 may include a top surface 1312 and an outer side surface 1311, the top surface 1312 may be opposite to the top wall 1321 of the mounting portion 132, and the outer side surface 1311 may be located on the outside of the top surface 1312, wherein the outside of the top surface 1312 refers to the side facing away from the inner center of the annular main body 131.

[0200] A first positioning groove 1313 can be set on the top surface 1312, and an opening 1314 can be opened on the outer side surface 1311. The opening 1314 is connected to the first positioning groove 1313. In this way, during assembly, the elastic member 18 can be inserted into the first positioning groove 1313 through the opening 1314, thereby achieving precise positioning of the elastic member 18 and facilitating the installation of the guide member 19 and the matching arrangement with the elastic member 18.

[0201] It is understandable that the number of the first positioning grooves 1313 and the openings 1314 may correspond to the number of the elastic members 18 .

[0202] For example, a second positioning groove 1315 can be further provided on the top surface 1312, and the first guide member 191 can be located in the second positioning groove 1315. The second positioning groove 1315 can play an auxiliary positioning role in the precise assembly of the first guide member 191 and the linkage member 17. For example, when the linkage member 17 is assembled in the accommodating space 133, the second positioning groove 1315 can be made to correspond to the matching portion 172 of the linkage member 17, thereby improving the precise positioning of the linkage member 17 and facilitating the fitting and coordination of the first guide member 191 with the matching portion 172 of the linkage member 17 during installation.

[0203] As shown in FIG. 14 , an opening 1316 may be further defined on the outer side surface 1311 of the main body 131 , and the opening 1316 may be in communication with the second positioning groove 1315 .

[0204] FIG15 is a schematic structural diagram of the rotating member in FIG14 .

[0205] For example, as shown in Figure 15, the number of guide members 19 in each accommodating space 133 can be three, such as a first guide member 191, a second guide member 192 and a third guide member 193, and the second guide member 192 and the third guide member 193 are located on both sides of the first guide member 191. For example, the second guide member 192 and the third guide member 193 can be respectively located on both sides of the first guide member 191 along the rotation direction of the rotating member 13.

[0206] The linkage member 17 may include a connected mating portion 172, a first extension portion 173 and a second extension portion 174. The first slider 171 of the linkage member 17 may be set on the mating portion 172, so that the linkage member 17 can be inserted and mated with the first slide rail on the lifting member through the first slider 171 on the mating portion 172.

[0207] The first extension portion 173 and the second extension portion 174 may be located on both sides of the matching portion 172 , respectively. For example, the first extension portion 173 and the second extension portion 174 may be located on both sides of the matching portion 172 along the rotation direction of the rotating member 13 .

[0208] The mating portion 172 can be disposed around the first guide member 191, the first extension portion 173 can be disposed around the second guide member 192, and the second extension portion 174 can be disposed around the third guide member 193. For example, the mating portion 172 can have a first positioning hole 172a (see FIG. 14 ), through which the mating portion 172 can be mounted on the first guide member 191. The first extension portion 173 can have a second positioning hole 173a (see FIG. 14 ), through which the first extension portion 173 can be mounted on the second guide member 192. The second extension portion 174 can also have a third positioning hole 174a (see FIG. 14 ), through which the second extension portion 174 can be mounted on the third guide member 193.

[0209] For example, the thickness of the mating portion 172 can be greater than the thickness of the first extension portion 173. It should be noted that in this embodiment of the present application, thickness refers to the height along the thickness direction. The thickness of the mating portion 172 can be the distance in the thickness direction (z-direction) from the side of the mating portion 172 facing the main body 131 to the side of the mating portion 172 facing the top wall of the mounting portion 132. The thickness of the first extension portion 173 can also be the distance from the side of the first extension portion 173 facing the main body 131 to the side of the first extension portion 173 facing the top wall of the mounting portion 132.

[0210] Figure 15a is a front view of the assembled linkage member and guide member in Figure 15. For example, the thickness of the mating portion 172 may be h1 in Figure 15a, and the thickness of the first extension portion 173 may be h2 in Figure 15a, where h1 is greater than h2.

[0211] That is, in the thickness direction, the distance between the matching part 172 and the first guide part 191 to achieve guiding cooperation is greater than the distance between the first extension part 173 and the second guide part 192 to achieve guiding cooperation, and the guiding effect between the first guide part 191 and the matching part 172 is better than the guiding effect between the first extension part 173 and the second guide part 192. The first guide part 191 can be used to precisely position the matching part 172 (i.e., the linkage part 17), and the second guide part 192 can be used to roughly position the first extension part 173 (i.e., the linkage part 17). The combination of the two ensures the smoothness of guidance in the buffering scenario, which is conducive to reducing the installation accuracy requirements and installation difficulty, improving the assemblability, and facilitating assembly.

[0212] The thickness of the second extension portion 174 may also be smaller than the thickness of the fitting portion 172. The thickness of the second extension portion 174 may also be the distance in the thickness direction between the side of the second extension portion 174 facing the main body portion 131 and the side of the first extension portion 173 facing the top wall of the mounting portion 132 (as shown in FIG15 ). The thickness of the second extension portion 174 may be as shown by h3 in FIG15a , where h1 is greater than h3. The rough positioning of the linkage member 17 is achieved by the third guide member 193, which has better feasibility for mass production assembly.

[0213] The thickness of the first extension portion 173 may be consistent with the thickness of the second extension portion 174 . Of course, in some examples, the thickness of the first extension portion 173 may be inconsistent with the thickness of the second extension portion 174 .

[0214] Continuing with FIG. 15 , the elastic member 18 can be disposed around the second guide member 192, located between the first extension portion 173 and the main body 131. The elastic member 18 is not disposed on the first guide member 191, which is provided with the mating portion 172. Because the mating portion 172 is inherently thicker, and given the requirement for a relatively low overall height of the rotating member 13, the elastic member 18 is located on the second guide member 192. This ensures a longer extension path for the elastic member 18, achieving a more effective cushioning effect. This ensures a cushioning effect while also reducing the thickness of the rotating member 13 and the entire lifting device.

[0215] An elastic member 18 may also be provided around the third guide member 193 , and the elastic member 18 is located between the second extension portion 174 and the main body 131 . The structural design of two elastic members 18 in one mounting portion 132 can achieve a better buffering effect.

[0216] Alternatively, in some examples, the number of guide members 19 in each receiving space 133 may also be two, for example, including only the first guide member 191 and the second guide member 192 . Accordingly, the linkage member 17 may also include only the matching portion 172 and the first extension portion 173 .

[0217] For example, the ratio of the thickness of the fitting part 172 to the thickness of the first extension part 173 can be in the range of 3.5 to 5, and the ratio of the thickness of the fitting part 172 to the thickness of the second extension part 174 can also be in the range of 3.5 to 5. The structure of the linkage part is reasonably designed so that the linkage part and the guide part can better achieve guiding cooperation by using the method of precise positioning and coarse positioning, with high buffering smoothness and high mass production assembly performance.

[0218] It should be noted that, to facilitate assembly, the mating portion 172 surrounds the first guide member 191, and a gap exists between the mating portion 172 and the first guide member 191. For example, if the mating portion 172 is sleeved onto the first guide member 191 through the first positioning hole, a gap exists between the circumferential inner surface of the first positioning hole and the circumferential outer surface of the first guide member 191.

[0219] The gap between the inner surface of the mating part 172 and the outer surface of the first guide part 191 can be 5μm to 10μm, further improving the guiding accuracy of the first guide part 191 to the mating part 172 (linkage part 17), ensuring the precise positioning and guiding of the first guide part 191 to the linkage part 17, and better improving the smoothness of the buffering.

[0220] Correspondingly, there is a gap between the inner surface of the first extension portion 173 and the outer surface of the second guide member 192 , that is, there is a gap between the circumferential inner surface of the second coordination hole and the circumferential outer surface of the second guide member 192 , and the gap may range from 20 μm to 30 μm.

[0221] A gap also exists between the inner surface of the second extension 174 and the outer surface of the third guide member 193, that is, a gap exists between the circumferential inner surface of the third coordination hole and the circumferential outer surface of the third guide member 193. This gap can also range from 20 μm to 30 μm. This allows the second and third guide members 192 and 193 to provide rough positioning and guidance for the linkage member 17, ensuring high buffering smoothness while facilitating assembly.

[0222] The first extension portion 173 , the second extension portion 174 and the matching portion 172 may be integrally formed, or may be formed separately and then assembled together by bonding, welding, threaded fixing, snap-fit ​​connection, or the like.

[0223] In an embodiment of the present application, the elastic member 18 is arranged around the guide member 19. Exemplarily, the elastic member 18 may only partially surround the guide member 19. For example, the elastic member 18 may include a head end and a tail end opposite to each other in the thickness direction, and only the head end or the tail end of the elastic member 18 may be sleeved on the guide member 19.

[0224] Alternatively, the guide member 19 may extend from the leading end of the elastic member 18 to the trailing end of the elastic member 18. In the thickness direction, the height of the guide member 19 may be greater than or equal to the height of the elastic member 18. It is understood that the height of the elastic member 18 refers to the height of the elastic member 18 in the thickness direction when the elastic member 18 is compressed and placed within the accommodating space 133 of the mounting seat. For example, referring to FIG15 , taking the second guide member 192 as an example, the height of the second guide member 192 is greater than the height of the elastic member 18. Throughout the entire extension and contraction path of the elastic member 18, the second guide member 192 can serve as a guide, ensuring the extension and contraction of the elastic member 18 in the thickness direction, thereby improving the smoothness of the buffer and helping to avoid buffer jamming, failure, and other issues.

[0225] Continuing to refer to FIG. 15 , the rotating member 13 further includes a transmission portion 135 . The transmission portion 135 is fixed to the main body 131 . For example, the transmission portion 135 may be fixed to the outer surface of the main body 131 .

[0226] FIG16 is a schematic diagram of the assembly structure of the base and the rotating member in the lifting device of FIG4 .

[0227] As shown in Figure 16, a driving mechanism 120 and a transmission mechanism 130 can also be set in the accommodating cavity 11a of the base 11. The transmission mechanism 130 cooperates with the driving mechanism 120 and the rotating part 13 respectively. For example, the transmission mechanism 130 can cooperate with the transmission part 135 of the rotating part 13, so that the driving mechanism 120 drives the rotating part 13 to rotate through the transmission mechanism 130.

[0228] The driving mechanism 120 may be an electric driving mechanism, a pneumatic driving mechanism, a hydraulic driving mechanism, etc. The transmission mechanism 130 may be a worm drive, a gear drive, an electromagnetic drive, etc.

[0229] For example, the driving mechanism 120 may include a driving portion 1201 and an output shaft 1202. For example, the driving mechanism 120 may be an electric motor, the motor body may serve as the driving portion 1201, and the motor shaft may serve as the output shaft 1202. The output shaft 1202 may be provided with a first tooth structure 1203.

[0230] The transmission mechanism 130 may be a gear assembly, which may include a plurality of gears 1301 . A rotating shaft 1302 may be provided on the base 11 , and the plurality of gears 1301 are rotatably provided on the rotating shaft 1302 , so that the plurality of gears 1301 are meshed and linked.

[0231] A second tooth structure 1351 (shown in conjunction with FIG. 15 ) may be provided on the outer sidewall 112 of the transmission portion 135. The output shaft 1202 of the drive mechanism 120 may engage with the gear 1301 of the transmission mechanism 130 via the first tooth structure 1203. The gear 1301 of the transmission mechanism 130 may engage with the second tooth structure 1351 on the transmission portion 135 of the rotating member 13. The drive portion 1201 of the drive mechanism 120 drives the output shaft 1202 to rotate, which in turn drives the gear 1301 of the transmission mechanism 130 to rotate. This, in turn, drives the transmission portion 135 and the rotating member 13 via the transmission mechanism 130 to rotate.

[0232] To further enhance reliability, as shown in FIG16 , a plurality of weight-reducing grooves 1352 (as shown in conjunction with FIG15 ) may be provided on the transmission portion 135 to reduce the weight of the transmission portion 135 and the entire rotating member 13, thereby reducing the moment of inertia and thereby minimizing or preventing damage to the transmission portion 135 caused by collision with the base 11 due to the moment of inertia. Furthermore, the rotational impact force on the gear assembly (transmission mechanism 130) caused by the weight of the transmission portion 135 during a fall or other event can be reduced, thereby protecting the transmission mechanism 130.

[0233] To limit the rotation of the rotating member 13 within the base 11, illustratively, and further referring to FIG. 16 , the base 11 may include a bottom wall 111 and side walls 112. The side walls 112 are disposed around the bottom wall 111, and the side walls 112 and the bottom wall 111 together define a receiving cavity 11a of the base 11. A cover plate is disposed on one end of the side wall 112 facing away from the bottom wall 111, and the rotating member 13 is located above the side of the bottom wall 111 facing the cover plate.

[0234] FIG16a is an enlarged schematic diagram of the partial structure of the assembly of the base and the rotating member in FIG16.

[0235] As shown in Figure 16a, a limiting groove 1111 can also be provided on the base 11. For example, a limiting groove 1111 is provided on the bottom wall 111 of the base 11. The limiting groove 1111 opens toward one side of the rotating part 13. The transmission part 135 of the rotating part 13 can pass through the opening and extend into the limiting groove 1111, that is, the transmission part 135 rotates in the limiting groove 1111. The limiting groove 1111 plays a limiting role to ensure the reliable rotation of the rotating part 13 in the base 11, and the limiting groove 1111 is designed to limit the arc of rotation of the rotating part 13 to adjust the lifting height of the lifting part 14 to meet different needs.

[0236] As shown in FIG16 , buffer pads 1112 may be provided at both ends of the limiting groove 1111 along the rotation direction of the rotating member 13, and at least a portion of the buffer pads 1112 may protrude within the limiting groove 1111. When the transmission portion 135 rotates to both ends of the limiting groove 1111, the transmission portion 135 may contact the buffer pads 1112, which may act as a buffer, thereby reducing or avoiding abnormal noise caused by the transmission portion 135 directly colliding with the ends of the limiting groove 1111, thereby improving the user experience.

[0237] The buffer pad 1112 may be a rubber pad. Of course, in some other examples, the buffer pad 1112 may also be other structural components that can play a buffering role.

[0238] Continuing with FIG. 16 and FIG. 16 a , an arc-shaped second slide rail 1114 may be further provided on the bottom wall 111 , and the second slide rail 1114 may be located in the limiting groove 1111 .

[0239] FIG16 b is a schematic structural diagram of the rotating member in FIG16 .

[0240] As shown in Figure 16b, there is a protruding second slider 1353 on the transmission part 135. Combined with Figure 16a, the second slider 1353 is located on the side of the transmission part 135 facing the bottom wall 111. The second slider 1353 can be inserted into the second slide rail 1114 and slide along the second slide rail 1114 to further ensure the rotation stability of the rotating part 13.

[0241] Of course, in some examples, a second slide rail 1114 may be provided on the transmission portion 135 of the rotating member 13 , and a second sliding block 1353 may be provided on the bottom wall 111 of the base 11 .

[0242] A second groove 1113 (as shown in FIG18 ) may also be provided on the side of the bottom wall 111 of the base 11 facing the rotating part 13. The second groove 1113 is used to accommodate a lubrication structure, which can play a lubricating role. For example, the lubrication structure can be lubricating grease, etc. When the rotating part 13 rotates relative to the bottom wall 111 of the base 11, the rotating part 13 can contact the lubrication structure in the second groove 1113, which is beneficial to improving the rotation smoothness of the rotating part 13 and improving the shaking and abnormal noise problem between the rotating part 13 and the base 11.

[0243] Among them, the second groove 1113 can be one, or there can be multiple second grooves 1113. Multiple second grooves 1113 can be evenly arranged along the rotating circumference of the rotating part. For example, the position of the second groove 1113 can correspond to the position of the main body 131 of the rotating part 13 in the thickness direction.

[0244] FIG17 is a schematic cross-sectional view of the assembly of the base, rotating member and cover plate in the lifting device of FIG4 .

[0245] For example, as shown in FIG17 , the cover plate 12 may have a stopper 121 (see FIG5 ) on the side facing the base 11. One end of the stopper 121 is fixed to the cover plate 12, and the other end of the stopper 121 extends toward the rotating member 13. A space for the rotating member 13 to rotate may be formed between the other end of the stopper 121 and the base 11. For example, a gap may be provided between the other end of the stopper 121 and the bottom wall of the base 11, and the rotating member 13 may be assembled and rotated within the gap. The stopper 121 serves to limit the rotating member 13. The stopper 121 and the base 11 jointly restrict the rotating member 13 from moving in the thickness direction, but rather from rotating within the base 11.

[0246] There may be one limiting member 121 . Alternatively, there may be multiple limiting members 121 , which may be arranged around the avoidance hole on the cover plate 12 , with a gap between two adjacent limiting members 121 .

[0247] The entire rotating member 13 can be located between the limiting member 121 and the base 11. Alternatively, only a portion of the rotating member 13 can be located between the limiting member 121 and the base 11. For example, taking multiple limiting members 121 as an example, the main body 131 of the rotating member 13 can be located in the rotation space defined between the limiting member 121 and the base 11, and the mounting portion 132 can be located in the gap between two adjacent limiting members 121. This allows the cover 12, base 11, and rotating member 13 to have a larger overlapping area in the thickness direction, thereby ensuring that the rotation of the rotating member 13 is limited, improving the integration level, and facilitating further reducing the thickness of the lifting device.

[0248] It is understandable that there is a gap between the end surface of the limiting member 121 facing away from the cover plate 12 and the main body 131 of the rotating member 13 to ensure smooth rotation of the rotating member 13 .

[0249] A third groove 1317 is provided on the side of the main body 131 of the rotating part 13 facing the cover plate 12 (limiting part 121). The third groove 1317 is used to accommodate a lubrication structure. The lubrication structure can play a lubricating role, which is beneficial to improving the rotation smoothness of the rotating part 13 and improving the problem of shaking and abnormal noise between the rotating part 13 and the cover plate 12 (limiting part 121).

[0250] The number of the third groove 1317 can also be one, or the number of the third groove 1317 can also be multiple, and the multiple third grooves 1317 can be evenly arranged along the circumference of the rotating part 13. For example, the third groove 1317 can at least partially overlap with the limiting part 121 on the cover plate 12 in the thickness direction.

[0251] Continuing with FIG17 , the cover plate 12 is disposed on the base 11, and a receiving cavity 12a can be enclosed between the cover plate 12 and the base 11. For example, the cover plate 12 is disposed over a portion of the receiving cavity 11a within the base 11 to enclose the receiving cavity 12a. At least the transmission mechanism 130 is located within the receiving cavity 12a. The transmission mechanism 130 is connected to the base 11 and the cover plate 12, respectively, to ensure a stable position within the receiving cavity 12a. For example, the ends of the rotating shaft 1302 of the transmission mechanism 130 are fixed to the base 11 and the cover plate 12, respectively.

[0252] Exemplarily, the accommodating cavity 12a can be located on one side of the rotating member 13. For example, the accommodating cavity 12a can be located on the radially outer side of the rotating member 13 along the rotating circumference, so that the accommodating cavity 12a and the rotating member 13 have an overlapping area in the thickness direction, which is conducive to further reducing the thickness of the lifting device.

[0253] It should be noted that the drive mechanism 120 may be located inside the accommodating cavity 12a, or the drive mechanism 120 may be located outside the accommodating cavity 12a. Alternatively, in some examples, the drive mechanism 120 may be located partially inside the accommodating cavity 12a and partially outside the accommodating cavity 12a.

[0254] FIG18 is a front view structural diagram of the assembly of the base and the driving mechanism in FIG17 .

[0255] For example, as shown in FIG. 18 , at least part of the output shaft 1202 of the driving mechanism 120 may be located within the accommodating cavity 12 a so that the output shaft 1202 cooperates with the transmission mechanism 130 and thereby drives the rotating member 13 to rotate.

[0256] It should be noted that, taking the transmission mechanism 130 as an example of a gear assembly, when the output shaft 1202 rotates to drive the gear 1301 of the transmission mechanism 130 to rotate (refer to Figure 17), due to the meshing action of the gear 1301 and the first tooth structure on the output shaft 1202, the output shaft 1202 may move, as shown in Figure 18, causing the output shaft 1202 to move away from or toward the driving part 1201 along the direction of the rotation axis of the output shaft 1202, resulting in displacement, collision and other abnormal noise problems between the output shaft 1202 and the internal structure of the driving part 1201.

[0257] As shown in FIG18 , a raised stopper 1115 can be provided on the base 11. Stopper 1115 is located within the accommodating cavity and on the side of the output shaft 1202 along the rotation axis facing away from the drive unit 1201. Stopper 1115 can limit the output shaft 1202, restricting its movement along the axis, thereby improving problems such as abnormal sounds and noises in the drive mechanism 120.

[0258] For example, the distance between the surface of the stopper 1115 facing the output shaft 1202 and the end surface of the output shaft 1202 facing away from the drive unit 1201 along the rotation axis can be 0.1 mm to 0.2 mm, that is, the gap between the stopper 1115 and the output shaft 1202 can be 0.1 mm to 0.2 mm. This limits the displacement of the output shaft 1202 while preventing the stopper 1115 from affecting the rotation of the output shaft 1202, so that the displacement of the output shaft 1202 will not impact the internal structure of the drive unit 1201 and cause abnormal noise or other problems.

[0259] In order to guide and limit the lifting and lowering of the lifting member 14, referring to Figure 18, a third slide rail 1121 can be provided on the side wall 112 of the base 11, and a third slider 142 is provided on the lifting member 14 (refer to Figure 17). The third slide rail 1121 can extend along the thickness direction, and the third slider 142 can be inserted into the third slide rail 1121 and slide along the third slide rail 1121. The guiding function of the third slide rail 1121 can ensure that the lifting member 14 can be lifted and moved along the thickness direction under the drive of the rotating member 13.

[0260] Of course, in some examples, a third sliding block 142 may be provided on the side wall 112 of the base 11 , and a third sliding rail 1121 may be provided on the lifting member 14 .

[0261] FIG19 is a schematic structural diagram of the lifting member in FIG17 .

[0262] The number of the third slider 142 can be one, or in some examples, the number of the third slider 142 can be multiple. For example, as shown in FIG19 , the number of the third slider 142 can be four. It is understood that the number of the third slide rails 1121 can correspond to the number of the third sliders 142.

[0263] Multiple third sliders 142 can be evenly distributed along the circumference of the lifting member 14. Multiple evenly distributed third sliders 142 can provide uniform support for the lifting member 14. When pressing the top protective cover 15 and the lifting device of the camera module, problems such as pressing depression and pressing shaking can be improved.

[0264] A flexible conductive member 110 may also be provided on the lifting member 14 . The flexible conductive member 110 has conductive properties. For example, the flexible conductive member 110 may be a flexible metal conductive member, a flexible circuit board, or the like.

[0265] FIG20 is a schematic structural diagram of the assembly of a base, a rotating part, and a lifting part in another lifting device provided in an embodiment of the present application.

[0266] As shown in Figure 20 , flexible conductive member 110 includes a first connection end 1101 and a second connection end 1103. First connection end 1101 can be electrically connected to lift member 14, while second connection end 1103 can be used to connect to an external circuit board. For example, lift member 14 can be grounded via flexible conductive member 110, meeting requirements for electrostatic protection of the camera module.

[0267] For example, as shown in Figure 20, a conductive member 160 can be provided on the base 11, and the second connection end 1103 of the flexible conductive member 110 can be fixed to the conductive member 160 on the base 11 and electrically connected to the main circuit board 105 of the electronic device 100 through the conductive member 160 on the base 11.

[0268] The conductive member 160 may be a conductive structure independently provided on the base 11 .

[0269] Alternatively, in some examples, the base 11 and the cover 12 may be fixedly assembled by a metal fixing member, and the conductive member 160 may be the metal fixing member. For example, the metal fixing member may be a screw, a pin, a clip, or the like.

[0270] Continuing with reference to FIG20 , the lifting device 10 may further include a flexible circuit board 150, which may be electrically connected to the conductive member 160 on the base 11, thereby realizing an electrical connection between the flexible conductive member 110 and the flexible circuit board 150, and the flexible circuit board 150 may be electrically connected to the main circuit board of the electronic device, thereby realizing an electrical connection between the lifting member 14 and the main circuit board of the electronic device.

[0271] In addition, the driving mechanism 120 may also be electrically connected to the flexible circuit board 150 to achieve control of the driving mechanism 120 .

[0272] FIG21 is a schematic diagram of a partially enlarged structure of the flexible conductive member in FIG20 .

[0273] 21 , the flexible conductive member 110 may further include an elastic telescopic section 1102, which is located between the first connection end 1101 and the second connection end 1103. The elastic telescopic section 1102 has an elastic margin.

[0274] For example, the elastic telescopic segment 1102 may include a bending segment 1102b and multiple cantilever segments 1102a, and the multiple cantilever segments 1102a are arranged at intervals in sequence, and the bending segments 1102b and the cantilever segments 1102a are alternately distributed in sequence. For example, the elastic telescopic segment 1102 in Figure 12 may include six bending segments 1102b and seven cantilever segments 1102a, and the seven cantilever segments 1102a are arranged at intervals, and the cantilever segments 1102a and the bending segments 1102b are alternately arranged in sequence, and a bending segment 1102b is connected between two adjacent cantilever segments 1102a.

[0275] The elastic expansion section 1102 thus formed is similar to a spring structure, and can be extended or contracted under the action of an external force, thereby preventing the flexible conductive member 110 from affecting the lifting and lowering movement of the lifting member 14. When the lifting member 14 moves upward along the thickness direction away from the rotating member 13, the movement of the lifting member 14 drives the first connecting end 1101 to move, allowing the elastic expansion section 1102 to extend. Conversely, when the lifting member 14 moves downward along the thickness direction toward the rotating member 13, the movement of the lifting member 14 drives the first connecting end 1101 to move, allowing the elastic expansion section 1102 to contract.

[0276] The flexible conductive element 110 may be formed by bending a thin strip of flexible circuit board, or the flexible conductive element 110 may be formed by bending a thin strip of metal structure, for example, by bending a copper metal wire.

[0277] FIG22 is a schematic diagram of a partially disassembled structure of the lifting device in FIG4 .

[0278] As shown in FIG. 22 , one end of the lifting member 14 cooperates with the rotating member 13 in the base 11 , and the other end of the lifting member 14 can extend out of the base 11 through the avoidance hole on the cover 12 .

[0279] To achieve the connection between the lifting member 14 and the side protective cover 16 and the top protective cover 15 , illustratively, the other end of the lifting member 14 may have a first mounting platform 144 , and the first mounting platform 144 may be arranged around the other end of the lifting member 14 .

[0280] A second mounting platform 125 may be provided on the cover plate 12 , and the second mounting platform 125 may be arranged around the avoidance hole on the cover plate 12 . One end of the side protective cover 16 may be fixed on the second mounting platform 125 , and the other end of the side protective cover 16 may be fixed on the first mounting platform 144 .

[0281] For example, the two ends of the side protective cover 16 can be fixed to the first mounting platform 144 and the second mounting platform 125 by bonding. Of course, in some other examples, the two ends of the side protective cover 16 can also be fixed to the first mounting platform 144 and the second mounting platform 125 by other means such as clamping, threaded fastening, etc.

[0282] The other end of the lifting member 14 can be partially mounted in the top protective cover 15. For example, the end 14a of the other end of the lifting member 14 can protrude from the first mounting platform 144, and the end 14a of the other end of the lifting member 14 can be mounted in the top protective cover 15 (see Figure 23).

[0283] It is understood that the top protective cover 15, the cover plate 12, and the side protective cover 16 can enclose the accommodating cavity of the base 11 into a closed space (see FIG6 ). To meet the ventilation requirements of the camera module, as shown in FIG22 , a waterproof breathable member 113 can be provided on the base 11. The accommodating cavity inside the base 11 and the exterior of the base 11 can be connected via the waterproof breathable member 113. The waterproof breathable member 113 can include a waterproof breathable membrane that allows gas to pass but prevents liquid from passing, thereby meeting the ventilation requirements of the camera module and ensuring the waterproof performance of the camera module.

[0284] There may be one waterproof breathable member 113 , or there may be multiple waterproof breathable members 113 . For example, two waterproof breathable members 113 may be provided on the side wall of the base 11 .

[0285] For example, the other end of the lifting member 14 can be fixed to the top protective cover 15 by bonding.

[0286] FIG23 is a partial enlarged schematic diagram of portion A in FIG7 .

[0287] As shown in FIG. 23 , an adhesive layer 140 may be provided between the outer wall of the end portion 14 a at the other end of the lifting member 14 and the inner wall of the top protective cover 15 , and the lifting member 14 is fixed to the top protective cover 15 via the adhesive layer 140 .

[0288] In order to further enhance the assembly strength of the lifting member 14 and the top protective cover 15 , a fourth groove 143 may be provided on the outer wall of the other end portion 14 a of the lifting member 14 (see FIG. 24 ).

[0289] FIG24 is a schematic structural diagram of the top protective cover 15 in FIG22 .

[0290] As shown in FIG24 , a fifth groove 153 may be provided on the inner wall of the top protective cover 15 . As shown in FIG23 , the adhesive layer 140 may be filled in the fourth groove 143 and the fifth groove 153 . On the one hand, the fourth groove 143 and the fifth groove 153 increase the bonding area between the adhesive layer 140 and the lifting member 14 and the top protective cover 15 , thereby improving the bonding strength. On the other hand, the adhesive layer 140 located in the fourth groove 143 and the fifth groove 153 forms an inverted structure, further enhancing the bonding performance and preventing the top protective cover 15 from falling off in scenarios such as falling.

[0291] In the embodiment of the present application, the cover plate 12 can be a plate-like structural member integrally mounted on the base 11 (see FIG17 ). The cover plate 12 and a portion of the receiving cavity of the base 11 enclose a receiving cavity 12a for accommodating the transmission mechanism 130. The transmission mechanism 130 can be secured to the cover plate 12 and the base 11, respectively. For example, using the transmission mechanism 130 as an example, the ends of the rotating shaft 1302 of the gear assembly can be secured to the cover plate 12 and the base 11, respectively, thereby assembling the multiple gears 1301 of the gear assembly within the receiving cavity 12a.

[0292] For example, one end of the rotating shaft 1302 can be fixed on the base 11 , and a shaft hole can be provided on the cover plate 12 . The cover plate 12 is covered on the base 11 , and the other end of the rotating shaft 1302 can be fixed in the shaft hole.

[0293] It should be noted that the cover 12 and the base 11 need to be aligned and fixed. For example, taking the cover 12 and the base 11 as an example of being fixedly connected by screws and mating nuts, a plurality of first positioning holes 124 are provided on the cover 12 (as shown in FIG5 ), and a plurality of second positioning holes 114 are provided on the base 11 (as shown in FIG5 ). The cover 12 is covered on the base 11, and the first positioning holes 124 and the second positioning holes 114 need to be aligned so that the screws can pass through the second positioning holes 114 and the first positioning holes 124 respectively and engage with the mating nut threads to achieve the fixation of the cover 12 and the base 11.

[0294] Due to the influence of assembly and production accuracy, after the first positioning hole 124 and the second positioning hole 114 of the cover 12 are aligned, there may be an alignment deviation between the axis hole on the cover 12 and the rotating shaft 1302 on the base 11, and the rotating shaft 1302 may be skewed, thereby affecting the transmission effect of the transmission mechanism 130, and may even cause the transmission to be realized, affecting the lifting and lowering movement of the lifting member 14.

[0295] Figure 25 is a structural schematic diagram of another lifting device provided in an embodiment of the present application.

[0296] In some embodiments, as shown in FIG. 25 , the cover plate 12 may include a first cover body 122 and a second cover body 123 , that is, the cover plate 12 may include two independent cover bodies, and the second cover body 123 may be fixedly disposed on the first cover body 122 .

[0297] FIG26 is a schematic diagram of the cross-sectional structure of the lifting device at the second cover body in FIG25 .

[0298] As shown in FIG. 26 , the first cover 122 is fixed to the base 11 . For example, the first cover 122 and the base 11 can be fixed together by means of the above-mentioned screws and matching nuts.

[0299] The second cover 123 is fixed to the transmission mechanism 130, such as the second cover 123 is fixed to the rotating shaft 1302 of the transmission mechanism 130, so that the first cover 122 and the second cover 123 are two independent structural parts assembled together, decoupling the alignment tolerance of the assembly of the cover plate 12 and the base 11 and the alignment tolerance of the assembly of the cover plate 12 and the transmission mechanism 130. The assembly gap between the first cover 122 and the second cover 123 can absorb the tolerance caused by the assembly alignment of the first cover 122 and the base 11, ensure the precise alignment of the second cover 123 and the transmission mechanism 130, prevent the problem of skewness of the rotating shaft during assembly due to too many positioning holes, over-positioning, etc., and ensure the transmission effect.

[0300] The second cover 123 may have a shaft hole on a side facing the base 11 , and the end of the rotating shaft 1302 of the transmission mechanism facing away from the base 11 may be inserted and fixed in the shaft hole.

[0301] FIG27 is a schematic diagram of the disassembled structure of the cover plate in the lifting device of FIG25 .

[0302] To achieve the assembly of the first cover 122 and the second cover 123 , illustratively, as shown in FIG. 27 , a second through hole 1221 may be opened on the first cover 122 , and the second cover 123 is mounted on the second through hole 1221 .

[0303] The second cover 123 may include a fixing portion 1231 and a protruding portion 1232 . The protruding portion 1232 is disposed on the fixing portion 1231 , and the fixing portion 1231 is fixed to the transmission mechanism.

[0304] It should be noted that the fixing portion 1231 and the raised portion 1232 can be an integrated structural part, or the fixing portion 1231 and the raised portion 1232 can be formed separately, and the fixing portion 1231 and the raised portion 1232 can be assembled together by bonding, welding, clamping, connecting with fixing parts, etc.

[0305] As shown in FIG26 , the protrusion 1232 can be inserted and fixed in the second through hole 1221. The side of the fixing portion 1231 provided with the protrusion 1232 abuts against the side of the first cover 122 facing the base 11. The fixing portion 1231 is fixedly connected to the base 11. The insertion of the protrusion 1232 in the second through hole 1221 and the abutment of the fixing portion 1231 with the first cover 122 both serve as an assembly positioning function, facilitating assembly. In addition, the first cover 122 and the second cover 123 have a larger contact area, which provides higher reliability.

[0306] The first cover 122 and the second cover 123 can be fixed by bonding, welding, screw fastening, clamping, or the like. For example, taking the bonding of the first cover 122 and the second cover 123 as an example, during actual assembly, the second cover 123 can first be engaged with the rotating shaft 1302 on the base 11, and then a layer of adhesive can be applied to the circumferential outer wall of the protrusion 1232 and the surface of the fixing portion 1231 facing away from the base 11. The first cover 122 is then placed on the base 11, and the protrusion 1232 is inserted into the second through hole 1221. The outer wall of the protrusion 1232 and the inner wall of the second through hole 1221 can be bonded together, so that the surface of the fixing portion 1231 facing away from the base 11 abuts against the surface of the first cover 122 facing the base 11 and the two are bonded together. This results in a large bonding area and high assembly strength. Moreover, by squeezing the adhesive layer, assembly tolerances can be more easily absorbed, ensuring a good transmission effect.

For example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements.
