[0003] However, when the camera extends out of the terminal, it is susceptible to external impacts. The impact force is transmitted to the lifting device that controls its raising and lowering, causing the lifting device to be easily damaged or even malfunction, thus failing to provide the normal raising and lowering function.
[0004] Therefore, improving the reliability of camera lifting devices has become an urgent problem to be solved. Summary of the Invention

[0037] With the development of smart terminals, the functions and designs of terminals are becoming increasingly complex. Pop-up cameras, which can simultaneously meet the needs of terminal slim design and lens zoom, are gradually becoming the mainstream structure on terminals.
[0038] However, when the camera extends out of the terminal, it is susceptible to external impacts. The impact force is transmitted to the lifting device that controls its raising and lowering, causing the lifting device to be easily damaged or even malfunction, thus failing to provide the normal raising and lowering function.
[0039] Based on the above-mentioned technical problems, this application provides a camera lifting device. By providing a first buffer and a second buffer, the camera lifting device can absorb or even eliminate impact forces from different external directions, preventing damage or failure, and improving its reliability and service life.
[0040] The camera lifting device provided in this application embodiment can be manufactured and sold separately as an independent component. Of course, it can also be used in camera modules and as a component of camera modules to improve the reliability of camera modules.
[0041] The following is combined with Figures 1 to 11 This application describes a camera lifting device 100, a camera module 1, and an electronic device provided according to embodiments of the present application.
[0042] Please refer to the following: Figures 1 to 7 This application provides a camera lifting device 100, including a base 10, a lifting mechanism 20, a transmission mechanism 30, and a buffer assembly. The lifting mechanism 20 is disposed on one side of the base 10 along a first direction X. The lifting mechanism 20 includes a lifting ring 21 and a decorative ring 22. The lifting ring 21 is movably connected to the base 10 along the first direction X, and the decorative ring 22 is disposed on the side of the lifting ring 21 facing away from the base 10 along the first direction X. The transmission mechanism 30 is disposed between the base 10 and the lifting mechanism 20. The transmission mechanism 30 includes a transmission member 31 and a guide member 32. The guide member 32 is rotatably connected to the base 10 via the transmission member 31 and movably connected to the lifting ring 21 to drive the lifting ring 21 to move along the first direction X. The buffer assembly includes a first buffer 41 and a second buffer 42. The first buffer 41 is connected between the decorative ring 22 and the lifting ring 21 so that the decorative ring 22 has a degree of rotational freedom relative to the lifting ring 21. The second buffer 42 is connected between the guide 32 and the transmission member 31 so that the guide 32 has a degree of movement freedom relative to the transmission member 31 in the first direction X.
[0043] It is understood that the camera lifting device 100 provided in this application embodiment can be used in the camera module 1, wherein the first direction X is the same as the optical axis direction of the camera component 200 in the camera module 1.
[0044] The base 10 is used to support and fix the lifting mechanism 20, the transmission mechanism 30 and the buffer assembly, and is used to connect with the camera module 1 and components on the electronic equipment to form a whole.
[0045] The lifting mechanism 20 is connected to one side of the base 10 along the first direction X and can move relative to the base 10 along the first direction X. Specifically, the lifting mechanism 20 can move away from the base 10 along the first direction X and can also move towards the base 10 along the first direction X. It can be understood that when the camera lifting device 100 provided in this application embodiment is used for the camera module 1 to be installed on an electronic device, the lifting mechanism 20 can extend out of the surface of the electronic device along the first direction X and can also retract to the initial position along the first direction X to meet the zoom requirements of the camera module 1.
[0046] The transmission mechanism 30 is connected between the lifting mechanism 20 and the base 10 along the first direction X, and can rotate relative to the base 10. For example, the transmission mechanism 30 rotates clockwise to drive the lifting mechanism 20 to move away from the base 10 along the first direction X, and the transmission mechanism 30 rotates counterclockwise to drive the lifting mechanism 20 to move towards the base 10 along the first direction X.
[0047] Specifically, the lifting mechanism 20 includes a lifting ring 21 and a decorative ring 22 connected along the first direction X, with a first buffer 41 connecting the lifting ring 21 and the decorative ring 22. The transmission mechanism 30 includes a guide 32 and a transmission member 31 connected along the first direction X, with a second buffer 42 connecting the guide 32 and the moving member. Figure 5 As shown, the base 10, transmission component 31, second buffer component 42, guide component 32, lifting ring 21, first buffer component 41 and decorative ring 22 are arranged in sequence along the first direction X.
[0048] Under normal operating conditions, the decorative ring 22 of the camera lifting device 100 can be in a retracted or extended state to meet the different focal length shooting requirements of the camera assembly 200, such as... Figure 6 As shown, Figure 6 This can represent the structure when the camera lifting device 100 or the decorative ring 22 is in the retracted state, that is, when the decorative ring 22 does not extend beyond the cover plate 3 of the electronic device; such as Figure 7 As shown, Figure 7 This can represent the structure when the camera lifting device 100 or the decorative ring 22 is in the extended state, that is, the decorative ring 22 extends out of the cover plate 3 of the electronic device.
[0049] The process of the decorative ring 22 switching from a retracted state to an extended state is as follows: the transmission member 31 rotates and drives the guide member 32 to rotate. The guide member 32 rotates to drive the lifting ring 21 to move away from the base 10 along the first direction X. The lifting ring 21 moves to drive the decorative ring 22 to move away from the base 10 along the first direction X, so that the decorative ring 22 is extended. Correspondingly, the transmission member 31 moves in the opposite direction to drive the guide member 32 to rotate in the opposite direction. The guide member 32 rotates to drive the lifting ring 21 to move towards the base 10 along the first direction X. The lifting ring 21 moves to drive the decorative ring 22 to move towards the base 10 along the first direction X, so that the decorative ring 22 switches from an extended state to a retracted state.
[0050] Under normal operating conditions, the torque on the first buffer 41 is not greater than a preset torque that allows it to displace relative to the lifting ring 21. The lifting ring 21 and the decorative ring 22 move synchronously along the first direction X without relative rotation. Similarly, the torque on the second buffer 42 is not greater than a preset torque that allows it to displace relative to the transmission member 31. The guide member 32 rotates synchronously with the transmission member 31 without relative movement along the first direction X. The preset torques of the first buffer 41 and the second buffer 42 can be adjusted according to requirements by changing their shape or using components with different structures.
[0051] As an example, the first buffer 41 and the second buffer 42 can both adopt a structure that can deform. That is, when the torque on the first buffer 41 or the second buffer 42 is greater than their respective preset torque, the first buffer 41 and the second buffer 42 can deform to absorb the torque they receive.
[0052] like Figure 7 As shown, when the camera lifting device 100 is subjected to an external impact, specifically, when the decorative ring 22 is in the extended state and is subjected to an external impact inclined in the first direction X, or is subjected to an external rotational impact, the torque of the decorative ring 22 suddenly increases. This torque is transmitted to the first buffer 41. If this torque is greater than the preset torque at which the first buffer 41 can deform, the first buffer 41 deforms to make the decorative ring 22 rotate relative to the lifting ring 21. In this way, the impact force is absorbed or even eliminated, thereby reducing or eliminating the impact on other components. When the impact on the decorative ring 22 ends, the first buffer 41 can return to its initial shape so that the decorative ring 22 rotates relative to the lifting ring 21 in the opposite direction to the initial position.
[0053] When the decorative ring 22 is in the extended state and is impacted by an external force along the first direction X, the impact force is transmitted sequentially through the decorative ring 22, the lifting ring 21, and the guide member 32 to the second buffer member 42. When the torque transmitted to the second buffer member 42 by this impact is greater than the preset torque that allows it to deform, the second buffer member 42 can deform in the first direction X to make the guide member 32 move relative to the transmission member 31 towards the base 10 along the first direction X. In this way, the impact can be absorbed or even eliminated, thereby reducing or eliminating the impact on other components. When the impact on the decorative ring 22 ends, the second buffer member 42 can return to its initial shape so that the guide member 32 moves relative to the transmission member 31 away from the base 10 along the first direction X to the initial position.
[0054] The camera lifting device 100 provided in some embodiments of this application, by providing a first buffer 41 between the decorative ring 22 and the lifting ring 21, allows the decorative ring 22 to have rotational freedom relative to the lifting ring 21 when the camera lifting device 100 is subjected to an external impact tilted in the first direction X, so as to absorb or even eliminate the impact force; and by providing a second buffer 42 between the guide member 32 and the transmission member 31, allows the guide member 32 to have movement freedom relative to the transmission member 31 in the first direction X when the camera lifting device 100 is subjected to an external impact along the first direction X, so as to absorb or even eliminate the impact force. The camera lifting device 100 can absorb or even eliminate impact forces from different external directions, prevent damage or failure, and improve its reliability and service life.
[0055] The camera lifting device 100 provided in some embodiments of this application can realize its telescopic function by driving the lifting mechanism 20 to move along the first direction X through the rotation of the transmission mechanism 30.
[0056] Optionally, the decorative ring 22 and the lifting ring 21 are provided separately, and they are arranged to abut against each other on one side surface along the first direction X, which helps to improve the stability of the transmission and also helps to improve the structural compactness.
[0057] The first buffer 41 can be bonded between the decorative ring 22 and the lifting ring 21, or it can be set between the decorative ring 22 and the lifting ring 21 by snap-fit or welding.
[0058] Optionally, the guide 32 and the transmission 31 are provided separately, and they are arranged to abut against each other on one side surface along the first direction X, which helps to improve the stability of the transmission and also helps to improve the structural compactness.
[0059] The second buffer 42 can be bonded between the guide 32 and the transmission 31, or it can be set between the guide 32 and the transmission 31 by snap-fit or welding.
[0060] Optionally, the base 10, transmission component 31, second buffer component 42, guide component 32, lifting ring 21, first buffer component 41, and decorative ring 22 can all be configured as annular structures.
[0061] Please see Figure 5 According to one aspect of the embodiments of this application, the number of first buffers 41 is set to at least two, and the at least two first buffers 41 are distributed at circumferential Y intervals along the lifting ring 21.
[0062] The number of the first buffer 41 can be set to two, three, or more, and its specific number can be designed according to the specific structure of the lifting mechanism 20.
[0063] In this embodiment of the application, the number of first buffer members 41 can be four. The four first buffer members 41 are evenly distributed at equal intervals along the circumferential Y direction. By setting them in this way, the force between the decorative ring 22 and the lifting ring 21 can be more uniform, and the decorative ring 22 can rotate more stably relative to the lifting ring 21, so as to better resist external impacts and thus improve the reliability of the camera lifting device 100.
[0064] According to one aspect of the embodiments of this application, the number of second buffers 42 is set to at least two, and the at least two second buffers 42 are distributed at circumferential Y intervals along the lifting ring 21.
[0065] The number of the second buffer 42 can be set to two, three, or more, and its specific number can be designed according to the specific structure of the transmission mechanism 30.
[0066] In this embodiment, the number of second buffers 42 can be six. The six second buffers 42 are evenly distributed at equal intervals along the circumferential Y direction. By setting them in this way, the force between the guide 32 and the transmission 31 can be more uniform, and the guide 32 can move more stably relative to the transmission 31 along the first direction X, so as to better resist external impacts and thus improve the reliability of the camera lifting device 100.
[0067] Please continue reading. Figure 5 According to one aspect of the embodiments of this application, one of the decorative ring 22 and the lifting ring 21 is provided with a toothed portion 211, and the other is connected to one end of the first buffer member 41 along the first direction X. The toothed portion 211 extends along the circumferential direction Y of the lifting ring 21, and the other end of the first buffer member 41 along the first direction X is movably connected to the toothed portion 211.
[0068] The toothed portion 211 can be understood as having a structure with alternating concave and convex portions in the circumferential direction Y. Under normal operating conditions, one end of the first buffer member 41 along the first direction X can be disposed in the concave portion so that the decorative ring 22 and the lifting ring 21 are abutted against each other on one side surface along the first direction X.
[0069] The length of the concave and convex parts along the circumferential Y direction can be the same or different. That is, the distance between two adjacent concave parts along the circumferential Y direction can be the same or different. Correspondingly, the distance between two adjacent convex parts can be the same or different.
[0070] For example, the concave and convex portions are configured with the same length dimension along the circumferential Y direction.
[0071] The toothed portion 211 extends circumferentially Y along the lifting ring 21. Optionally, the toothed portion 211 can be a continuous full ring structure. Of course, it can also be a discontinuous, intermittent ring structure.
[0072] In some embodiments, the decorative ring 22 is provided with teeth 211. One end of the first buffer member 41 is connected to the lifting ring 21 along the first direction X, and the other end is movably connected to the teeth 211. When the torque on the first buffer member 41 is greater than the preset force that allows it to deform, the first buffer member 41 can provide the teeth 211 with a force along the circumferential direction Y to push against the teeth 211 and thereby drive the decorative ring 22 to rotate relative to the lifting ring 21.
[0073] In some embodiments, the lifting ring 21 is provided with teeth 211, one end of the first buffer member 41 is connected to the decorative ring 22 along the first direction X, and the other end is movably connected to the teeth 211. When the torque on the first buffer member 41 is greater than the preset torque that allows it to deform, the first buffer member 41 can move in the teeth 211 to drive the decorative ring 22 to rotate relative to the lifting ring 21.
[0074] For example, the first buffer 41 can be moved from one of the recesses to the adjacent protrusion; or, the first buffer 41 can be moved from one of the recesses to another recess to drive the decorative ring 22 to rotate relative to the lifting ring 21.
[0075] Optionally, the tooth 211 can be configured as a toothed groove structure, and the first buffer 41 can include a toothed structure, the two of which can mesh together axially.
[0076] Optionally, the tooth 211 can be configured as a rectangular groove structure, that is, along the circumferential Y direction, the orthographic projection of the concave part and the orthographic projection of the convex part are both rectangular structures, and the first buffer 41 can include a spherical structure.
[0077] The camera lifting device 100 provided in some embodiments of this application helps to ensure the effectiveness of the first buffer 41 in buffering external impacts.
[0078] Please see Figures 7 to 10 According to one aspect of the embodiments of this application, the first buffer 41 includes an elastic member 411 and a ball 412. The ball 412 is connected to one end of the elastic member 411 facing away from the base 10 along the first direction X and is movably connected to the tooth 211. One end of the elastic member 411 facing the base 10 along the first direction X is connected to the decorative ring 22.
[0079] It can be understood that the decorative ring 22 is disposed on the side of the lifting ring 21 facing away from the base 10 along the first direction X, and one of the decorative ring 22 and the lifting ring 21 can be sleeved on the other along the first direction X, so that the teeth 211 of the lifting ring 21 can be located on the side of the decorative ring 22 facing away from the base 10 along the first direction X.
[0080] With this configuration, the ball bearing 412 can abut against the toothed part 211 under the force of the elastic member 411, so that the decorative ring 22 and the lifting ring 21 can be connected more tightly under the connection of the first buffer member 41.
[0081] The first buffer 41 includes an elastic element 411 and a ball 412 connected to each other. Optionally, when the tooth 211 is disposed on the decorative ring 22, the elastic element 411 is connected to the lifting ring 21, and the ball 412 is movably connected to the tooth 211; when the tooth 211 is disposed on the lifting ring 21, the elastic element 411 is connected to the decorative ring 22, and the ball 412 is movably connected to the tooth 211.
[0082] like Figure 7 and Figure 8 As shown, under normal operating conditions, the ball 412 of the camera lifting device 100 abuts against the tooth 211. Specifically, the ball 412 extends into the recess, that is, in the circumferential Y direction, the orthographic projection of the ball 412 overlaps with the orthographic projection of the tooth 211.
[0083] like Figure 9 and Figure 10 As shown, when the decorative ring 22 is in the extended state and is subjected to an external impact along the first direction X or an external rotational impact, the ball 412 can extend from the concave portion and abut against the convex portion, that is, in the circumferential direction Y, the orthographic projection of the ball 412 does not overlap with the orthographic projection of the tooth 211.
[0084] In some embodiments, the elastic element 411 may be configured as a spring, rubber, or sponge.
[0085] Please continue reading. Figure 5According to one aspect of the embodiments of this application, the decorative ring 22 includes a ring body 221 and a connecting portion 222. The connecting portion 222 is connected to the side of the ring body 221 facing the lifting ring 21 along the first direction X. The lifting ring 21 is recessed to form a tooth 211 along the side of the first direction X facing away from the decorative ring 22. The tooth 211 is located on the side of the connecting portion 222 facing away from the base 10 along the first direction X. The first buffer member 41 is connected to the connecting portion 222.
[0086] The connecting part 222 is connected to the ring body 221 on the side facing the lifting ring 21 along the first direction X and protrudes from the ring body 221. The lifting ring 21 has a tooth 211 on the side facing the decorative ring 22 along the first direction X. The tooth 211 can be formed by the lifting ring 21 recessed on the side facing away from the decorative ring 22 along the first direction X. The connecting part 222 extends into the inner ring surface of the tooth 211 along the first direction X and is located on the side of the tooth 211 facing the base 10 along the first direction X.
[0087] In some embodiments, the ball 412 is movably connected to the tooth 211, and the elastic element 411 is connected to the connecting portion 222, such as... Figure 5 and Figure 8 As shown, the ring body 221, the toothed part 211, the ball 412, the elastic element 411, and the connecting part 222 are arranged sequentially along the first direction X.
[0088] According to one aspect of the embodiments of this application, the second buffer 42 is capable of elongating or shortening along a first direction X, and the second buffer 42 includes any one of a spring, rubber, or sponge.
[0089] like Figure 6 and Figure 7 As shown, under normal operating conditions, when the torque on the second buffer 42 is less than or equal to the preset torque that causes it to deform, the second buffer 42 located between the guide 32 and the transmission 31 is always under pressure to connect the two and will not deform.
[0090] like Figure 11 As shown, when the decorative ring 22 is in the extended state and is subjected to an external impact along the first direction X, and the torque transmitted to the second buffer 42 by this impact is greater than the preset torque value that allows it to deform, the second buffer 42 shortens to absorb or even eliminate this impact, thereby reducing or eliminating the impact on other components; when the external impact disappears, the second buffer 42 extends to restore the initial compressed state, so that the guide 32 moves relative to the transmission member 31 along the first direction X away from the base 10 to the initial position.
[0091] The second buffer 42 can be made of spring, rubber, or sponge.
[0092] For example, the second buffer 42 is configured as a spring. Specifically, the guide 32 is provided with a first fixing part, which is connected to the side of the guide 32 facing the transmission member 31 along the first direction X and protrudes from the guide 32. The transmission member 31 is provided with a second fixing part, which is connected to the side of the transmission member 31 facing the guide 32 along the first direction X and protrudes from the transmission member 31. The spring is sleeved on the first fixing part along the first direction X and abuts against the guide 32, and on the other side is sleeved on the second fixing part and abuts against the transmission member 31.
[0093] Please continue reading. Figures 1 to 11 According to one aspect of the embodiments of this application, the camera lifting device 100 further includes a drive mechanism 50, which is connected to the base 10 and configured to drive the transmission member 31 to rotate.
[0094] The drive mechanism 50 is used to drive the transmission component 31 to rotate, so as to realize the lifting mechanism 20. Optionally, the drive mechanism 50 may include, but is not limited to, a motor or an electric motor.
[0095] The camera lifting device 100 provided in some embodiments of this application absorbs or even eliminates external impact forces by setting a first buffer 41 and a second buffer 42, preventing the impact force from being transmitted from the decorative ring 22 to the drive mechanism 50, so as to prevent damage to the drive mechanism 50 and the camera lifting device 100 from operating normally. This is beneficial to improving the reliability and service life of the drive mechanism 50, thereby improving the overall reliability.
[0096] In some embodiments, a reduction gear 60 is provided between the drive mechanism 50 and the transmission member 31 to transmit the rotational torque of the drive mechanism 50 to the transmission member 31.
[0097] The reduction gear 60 has the functions of reducing output speed, increasing torque and improving load capacity. By setting the reduction gear 60, higher torque output can be obtained, so that the transmission component 31 can achieve better rotation effect. In addition, it can also realize flexible change of power output direction to meet various working needs.
[0098] In some alternative embodiments, the camera lifting device 100 further includes a protective cover 70, a drive mechanism 50 and a reduction gear 60 disposed within the protective cover 70, which is used to protect the device and ensure safe operation.
[0099] Optionally, the base 10 also includes an adapter plate connected to the base body 11. The adapter plate is provided with a positioning rod. The reduction gear 60 is inserted into the positioning rod to be connected to the adapter plate. The drive mechanism 50 is provided on the adapter plate. The protective cover and the adapter plate enclose a protective cavity. The drive mechanism 50 and the reduction gear 60 are accommodated in the protective cavity.
[0100] For example, the transmission member 31 is configured as a ring structure, and the outer ring surface is provided with a gear that meshes with the reduction gear 60 to receive the drive of the drive mechanism 50.
[0101] According to one aspect of an embodiment of this application, the guide member 32 includes a first guide ring 321 and a second guide ring 322 distributed along a first direction X. A second buffer member 42 is connected between the first guide ring 321 and the transmission member 31, and the second guide ring 322 is movably connected to the lifting ring 21. The buffer assembly further includes a third buffer member 43, which is connected between the first guide ring 321 and the second guide ring 322, so that the first guide ring 321 has rotational freedom relative to the second guide ring 322.
[0102] The second buffer 42 is disposed between the first guide ring 321 and the transmission member 31. The first guide ring 321 is pressed against the second guide ring 322 by the pressure of the second buffer 42 and by the third buffer 43.
[0103] Under normal operating conditions, the first guide ring 321 and the second guide ring 322 rotate synchronously without relative rotation. When the drive mechanism 50 malfunctions, i.e., it suddenly provides an abnormally large torque to the transmission component 31, the transmission component 31 rotates and drives the first guide ring 321 to rotate. When the torque transmitted from the first guide ring 321 to the third buffer component 43 is greater than the preset torque required for the third buffer component 43 to remain stationary relative to the first guide ring 321 and the second guide ring 322, the third buffer component 43 can move relative to the first guide ring 321 and the second guide ring 322, causing the first guide ring 321 and the second guide ring 322 to rotate asynchronously. The rotation of the third buffer component 43 prevents the abnormal torque of the first guide ring 321 from being transmitted to the second guide ring 322. In this way, the impact of the malfunction of the drive mechanism 50 on other components is absorbed or even eliminated. When the abnormal torque of the drive mechanism 50 disappears, the relative positions of the first guide ring 321 and the second guide ring 322 are restored.
[0104] By providing a third buffer 43, the first guide ring 321 can rotate relative to the second guide ring 32 so that the two are staggered. Since the third buffer 43 is connected between the first guide ring 321 and the second guide ring 322, the third buffer 43 can limit the two, so that even if the two have rotational freedom, they will not be completely misaligned or the gap will increase.
[0105] Optionally, the third buffer 43 may include, but is not limited to, a spherical structure, an ellipsoidal structure, or a polygonal structure.
[0106] According to one aspect of the embodiments of this application, the number of third buffers 43 is set to two or more, and the two or more third buffers 43 are distributed at circumferential Y intervals along the lifting ring 21.
[0107] The number of the third buffer 43 can be set to two, three, or more, and its specific number can be designed according to the specific structure of the guide 32.
[0108] In this embodiment, the number of third buffers 43 can be four. The four third buffers 43 are evenly distributed at equal intervals along the circumferential Y direction. By setting them in this way, the force between the first guide ring 321 and the second guide ring 322 can be more uniform, and the second guide ring 322 can rotate more stably relative to the first guide ring 321, so as to better resist external impacts and thus improve the reliability of the camera lifting device 100.
[0109] According to one aspect of the embodiments of this application, the third buffer 43 includes a sphere, the first guide ring 321 is provided with a first groove 321a on the side facing the second guide ring 322, the second guide ring 322 is provided with a second groove 322a on the side facing the first guide ring 321, and the third buffer 43 abuts against the first groove 321a and the second groove 322a along the first direction X.
[0110] The third buffer 43 can be set in the form of a sphere, which is easy to obtain and helps to reduce costs.
[0111] By placing the third buffer 43 between the first groove 321a and the second groove 322a along the first direction X, the rotation of the first guide ring 321 can be transmitted to the second guide ring 322 through the third buffer 43 under normal operating conditions, so that the two can rotate synchronously.
[0112] According to one aspect of the embodiments of this application, the volume of the third buffer 43 is less than the sum of the volumes of the first groove 321a and the second groove 322a.
[0113] This can be understood as follows: the third buffer 43 abuts against the first groove 321a and the first groove 321a on both sides along the first direction X, and the third buffer 43 has gaps between itself and the first groove 321a and the first groove 321a on both sides along the circumferential direction Y.
[0114] By setting it in this way, the space enclosed by the first groove 321a and the second groove 322a can provide the third buffer 43 with a degree of freedom of movement. When the drive mechanism 50 malfunctions, the abnormal torque transmitted by the first guide ring 321 can drive the third buffer 43 to move, so that the abnormal torque cannot be transmitted to the second guide ring 322, which helps to improve the reliability of the camera lifting device 100.
[0115] Please see Figure 5 According to one aspect of the embodiments of this application, one of the lifting ring 21 and the second guide ring 322 is sleeved on the other. One of the lifting ring 21 and the second guide ring 322 is provided with a sliding part 3221, and the other is provided with a strip guide part 212. The sliding part 3221 is movably connected to the strip guide part 212.
[0116] Optionally, the strip guide 212 can be configured as a slide rail, and the sliding part 3221 can be configured as a slider to slide and engage with the slide rail; alternatively, the strip guide 212 can also be configured as a groove, and at least a portion of the sliding part 3221 extends into the groove to slide and engage with the groove.
[0117] For example, the second guide ring 322 is sleeved on the outer periphery of the lifting ring 21, and the inner ring surface of the second guide ring 322 is provided with a sliding part 3221. The outer periphery surface of the lifting ring 21 is provided with a strip-shaped guide part 212. The strip-shaped guide part 212 has a first end and a second end along its own extension direction, wherein the first end is disposed close to the base 10 relative to the second end along the first direction X.
[0118] Specifically, when the decorative ring 22 is in the retracted state, the sliding part 3221 is located at the second end of the strip guide part 212; when the decorative ring 22 switches from the retracted state to the extended state, the transmission member 31 drives the second guide ring 322 to rotate, and the sliding part 3221 moves from the first end to the second end to push the lifting ring 21 to move in one direction away from the base 10, so that the decorative ring 22 is in the extended state.
[0119] Of course, in other embodiments, the lifting ring 21 may also be sleeved on the outer periphery of the second guide ring 322, and the inner ring surface of the lifting ring 21 is provided with a sliding portion 3221, and the outer peripheral surface of the second guide ring 322 is provided with a strip-shaped guide portion 212; or, the lifting ring 21 may be sleeved on the outer periphery of the second guide ring 322, and the inner ring surface of the second guide ring 322 is provided with a sliding portion 3221, and the outer peripheral surface of the lifting ring 21 is provided with a strip-shaped guide portion 212; or, the second guide ring 322 may be sleeved on the outer periphery of the lifting ring 21, and the inner ring surface of the lifting ring 21 is provided with a sliding portion 3221, and the outer peripheral surface of the second guide ring 322 is provided with a strip-shaped guide portion 212.
[0120] In this way, the rotation of the second guide ring 322 can be converted into the movement of the lifting ring 21, so as to ensure the effectiveness of the camera lifting device 100 in extending and retracting along the first direction X. In addition, it can also make the structural design more compact and improve the space utilization of the camera lifting device 100.
[0121] According to one aspect of the embodiments of this application, the extension direction of the strip guide portion 212 is arranged to intersect with the first direction X.
[0122] In some embodiments, a portion of the strip guide portion 212 extends along the circumferential direction Y, and the extension direction of another portion intersects both the circumferential direction Y and the first direction X.
[0123] For example, the strip guide 212 is a bent structure. The strip guide 212 may include a first guide, a second guide and a third guide. The second guide is connected between the first guide and the third guide. The extension directions of the first guide and the third guide are the same as the circumferential Y direction. The extension direction of the second guide intersects the circumferential Y direction and the first direction X direction.
[0124] The end of the first guide portion facing away from the third guide portion is the first end portion, and the end of the third guide portion facing away from the first guide portion is the second end portion.
[0125] In other embodiments, all the strip guides 212 are arranged to extend in directions that intersect with the circumferential Y direction and the first direction X direction.
[0126] For example, the strip guide 212 has a straight structure.
[0127] like Figure 5 As shown, according to one aspect of an embodiment of this application, the base 10 includes a base body 11 and a limiting member 12. The limiting member 12 includes a first limiting part 121 and a second limiting part 122 that are intersected. The first limiting part 121 extends along a first direction X and is connected between the base body 11 and the second limiting part 122. The lifting ring 21 is movably connected to the first limiting part 121. The second limiting part 122 abuts against the guide member 32 on the side opposite to the base body 11 along the first direction X.
[0128] The lifting ring 21 can move and cooperate with the first limiting part 121 in the first direction X. The first limiting part 121 extends along the first direction X. By setting it in this way, it is beneficial to ensure that the lifting ring 21 only has the freedom to move in the first direction X, so as to ensure the reliability of the camera lifting device 100 in extending and retracting along the first direction X.
[0129] The second limiting part 122 abuts against the side of the guide member 32 facing away from the seat body 11 along the first direction X. Specifically, the second limiting part 122 abuts against the side of the second guide ring 322 facing away from the seat body 11 along the first direction X, so as to ensure that the guide member 32 will not come out along the first direction X during rotation, which helps to ensure the reliability of the camera lifting device 100.
[0130] Specifically, the guide member 32 and the transmission member 31 are disposed between the second limiting part 122 and the seat body 11. The second limiting part 122 and the seat body 11 can press the guide member 32 and the transmission member 31 against the second buffer member 42 to prevent the guide member 32 from coming out under the action of the second buffer member 42. In addition, the first guide ring 321 and the second guide ring 322 can press against the third buffer member 43 to ensure the effectiveness of the synchronous rotation of the first guide ring 321 and the second guide ring 322.
[0131] Optionally, the number of limiting members 12 can be set to one, two, or more.
[0132] For example, the number of limiting members 12 is set to two, and the two limiting members 12 are evenly distributed at equal intervals along the circumferential direction Y. This helps to save costs, improve the stability of the lifting ring 21 relative to its movement, and improve the limiting effect of the limiting members 12 on the guide member 32 along the first direction X, thereby improving the reliability of the camera lifting device 100.

[0134] The camera assembly 200 may include a lens 202 and a camera body 201.
[0135] Specifically, the lens 202 is fixedly connected to the decorative ring 22. It can be connected to the side of the decorative ring 22 facing away from the base 10 along the first direction X. It can also be embedded in the decorative ring 22 to protect the internal structure of the camera module 1.
[0136] The camera body 201 is disposed on the side of the base 10 facing away from the decorative ring 22 along the first direction X, so as to perform imaging function. Part of the camera body 201 can be extended or shortened along the first direction X to achieve zoom function. For example, at least part of the camera lifting device 100 is disposed around the outer periphery of the camera body 201, which helps to improve the structural compactness of the camera module 1, thereby facilitating the thinner and lighter design.
