For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] With the development of smart terminals, the functions and design forms of terminals are becoming more and more complex. The lifting camera has gradually become the mainstream structure on the terminal because it can take into account the terminal's lightweight design and lens zoom requirements at the same time.

[0038] However, when the camera is extended out of the terminal, it is susceptible to external impacts, and the impact force will be transmitted to the lifting device that controls the lifting of the camera, causing the lifting device to be easily damaged or even fail, and unable to provide the lifting function normally.

[0039] Based on the above technical problems, an embodiment of the present application provides a camera lifting device. By providing a first buffer member and a second buffer member, the camera lifting device can absorb or even eliminate impact forces from different external directions to prevent damage or failure, thereby improving its own reliability and service life.

[0040] The camera lifting device provided in the embodiment of the present application can be produced and sold separately as an independent component. Of course, it can also be used in a camera module and as a component of the camera module to improve the reliability of the camera module.

[0041] Combine the following Figures 1 to 11 The camera lifting device 100, the camera module 1 and the electronic device provided according to the embodiments of the present application are described.

[0042] Please also read Figures 1 to 7 The embodiment of the present application provides a camera lifting device 100, comprising a base 10, a lifting mechanism 20, a transmission mechanism 30 and a buffer assembly. The lifting mechanism 20 is arranged on one side of the base 10 along the first direction X, and the lifting mechanism 20 comprises 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 arranged on the side of the lifting ring 21 facing away from the base 10 along the first direction X. The transmission mechanism 30 is arranged between the base 10 and the lifting mechanism 20, and the transmission mechanism 30 comprises a transmission member 31 and a guide member 32. The guide member 32 is rotatably connected to the base 10 through the transmission member 31, and is 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 member 41 and a second buffer member 42. The first buffer member 41 is connected between the decorative ring 22 and the lifting ring 21 so that the decorative ring 22 has rotational freedom relative to the lifting ring 21. The second buffer member 42 is connected between the guide member 32 and the transmission member 31 so that the guide member 32 has movement freedom along the first direction X relative to the transmission member 31.

[0043] It is understandable that the camera lifting device 100 provided in the embodiment of the present application can be used in the camera module 1, wherein the first direction X is the same as the optical axis direction of the camera assembly 200 in the camera module 1.

[0044] The base 10 is used to carry 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 device 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 toward the base 10 along the first direction X. It can be understood that when the camera lifting device 100 provided in the embodiment of the present application is used for the camera module 1 to be installed on an electronic device, the lifting mechanism 20 can extend from 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 requirement 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. As an example, the transmission mechanism 30 rotates in a clockwise direction to drive the lifting mechanism 20 to move away from the base 10 along the first direction X, and the transmission mechanism 30 rotates in a counterclockwise direction to drive the lifting mechanism 20 to move toward 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, a first buffer 41 is connected between the lifting ring 21 and the decorative ring 22, and the transmission mechanism 30 includes a guide member 32 and a transmission member 31 connected along the first direction X, and the guide member 32 and the moving member are connected with a second buffer 42, such as Figure 5 As shown, the base 10 , the transmission member 31 , the second buffer member 42 , the guide member 32 , the lifting ring 21 , the first buffer member 41 and the decorative ring 22 are arranged in sequence along the first direction X.

[0048] When the camera lifting device 100 is in normal operation, the decorative ring 22 can be in a retracted state or an extended state to meet the photography requirements of the camera assembly 200 with different focal lengths, such as Figure 6 As shown, Figure 6 It can represent the structure when the camera lifting device 100 or the decorative ring 22 is in a retracted state, that is, the decorative ring 22 does not extend out of the cover plate 3 of the electronic device; Figure 7 As shown, Figure 7 It can represent the structure when the camera lifting device 100 or the decorative ring 22 is in an 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 the retracted state to the 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 along the first direction X away from the base 10; the lifting ring 21 moves to drive the decorative ring 22 to move along the first direction X away from the base 10, so that the decorative ring 22 is extended; accordingly, 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 along the first direction X toward the base 10; the lifting ring 21 moves to drive the decorative ring 22 to move along the first direction X toward the base 10, so that the decorative ring 22 switches from the extended state to the retracted state.

[0050] It can be understood that, under normal operating conditions, the torque applied to the first buffer 41 is not greater than the preset torque that enables it to be displaced 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, and the torque applied to the second buffer 42 is not greater than the preset torque that enables it to be displaced 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 achieved by changing their shapes or using components of different structures as required.

[0051] As an example, the first buffer 41 and the second buffer 42 can both adopt a structure that can undergo deformation, that is, when the torque applied to the first buffer 41 or the second buffer 42 is greater than their respective preset torques, the first buffer 41 and the second buffer 42 can deform to absorb the torques applied to them respectively.

[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 an extended state and is subjected to an external impact along an angle inclined to the first direction X, or is subjected to an external rotational impact, the torque of the decorative ring 22 suddenly increases, and this torque will be transmitted to the first buffer 41. If this torque is greater than the preset torque at which the first buffer 41 can be deformed, the first buffer 41 will be deformed to allow the decorative ring 22 to rotate relative to the lifting ring 21, thereby absorbing or even eliminating the impact force, thereby reducing or eliminating the impact of the impact on other components; when the impact on the decorative ring 22 ends, the first buffer 41 can restore its original shape, so that the decorative ring 22 can rotate in the opposite direction relative to the lifting ring 21 to the initial position.

[0053] When the decorative ring 22 is in an extended state and is impacted from the outside along the first direction X, the impact force is transmitted to the second buffer member 42 through the decorative ring 22, the lifting ring 21, and the guide member 32 in sequence. When the torque transmitted to the second buffer member 42 by this impact is greater than the preset torque at which it can be deformed, the second buffer member 42 can be deformed in the first direction X to make the guide member 32 move relative to the transmission member 31 along the first direction X toward the base 10, thereby absorbing or even eliminating the impact, thereby reducing or eliminating the impact of the impact on other components; when the impact on the decorative ring 22 ends, the second buffer member 42 can restore its original shape, so that the guide member 32 moves relative to the transmission member 31 along the first direction X back to the base 10 to the initial position.

[0054] The camera lifting device 100 provided in some embodiments of the present application, by setting a first buffer member 41 between the decorative ring 22 and the lifting ring 21, when the camera lifting device 100 is subjected to an external impact inclined in the first direction X, the first buffer member 41 can enable the decorative ring 22 to have a rotational freedom relative to the lifting ring 21 to absorb or even eliminate this impact force; and, by setting a second buffer member 42 between the guide member 32 and the transmission member 31, when the camera lifting device 100 is subjected to an external impact along the first direction X, the second buffer member 42 can enable the guide member 32 to have a movement freedom along the first direction X relative to the transmission member 31 to absorb or even eliminate this impact force. The camera lifting device 100 can absorb or even eliminate external impact forces from different directions to prevent it from being damaged or failing, which is beneficial to improving its own reliability and service life.

[0055] The camera lifting device 100 provided in some embodiments of the present 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 the surfaces of the two sides facing each other along the first direction X are arranged in abutment with each other, which is beneficial to improving the stability of the transmission and the compactness of the structure.

[0057] The first buffer member 41 may be bonded between the decorative ring 22 and the lifting ring 21 , or may be clamped or welded between the decorative ring 22 and the lifting ring 21 .

[0058] Optionally, the guide member 32 and the transmission member 31 are provided separately, and the two are arranged to abut against each other along the first direction X, which is beneficial to improving the stability of the transmission and the compactness of the structure.

[0059] The second buffer member 42 may be bonded between the guide member 32 and the transmission member 31 , or may be clamped or welded between the guide member 32 and the transmission member 31 .

[0060] Optionally, the base 10 , the transmission member 31 , the second buffer member 42 , the guide member 32 , the lifting ring 21 , the first buffer member 41 and the decorative ring 22 may all be configured as an annular structure.

[0061] See also Figure 5 According to one aspect of the embodiment of the present application, the number of the first buffer members 41 is set to at least two, and the at least two first buffer members 41 are spaced apart along the circumferential direction Y of the lifting ring 21 .

[0062] The number of the first buffer members 41 can be two, three, or more, and the specific number can be designed according to the specific structure of the lifting mechanism 20 .

[0063] In the embodiment of the present application, the number of the first buffer members 41 may be four, and the four first buffer members 41 are evenly distributed at equal intervals along the circumferential direction Y. By arranging in this manner, the force between the decorative ring 22 and the lifting ring 21 can be more uniform, and the decorative ring 22 can be ensured to rotate more stably relative to the lifting ring 21 to better resist external impacts, thereby helping to improve the reliability of the camera lifting device 100.

[0064] According to one aspect of the embodiment of the present application, the number of the second buffer members 42 is set to at least two, and the at least two second buffer members 42 are spaced apart along the circumferential direction Y of the lifting ring 21 .

[0065] The number of the second buffer members 42 can be two, three, or more, and the specific number can be designed according to the specific structure of the transmission mechanism 30 .

[0066] In the embodiment of the present application, the number of the second buffer members 42 may be six, and the six second buffer members 42 are evenly distributed at equal intervals along the circumferential direction Y. By arranging in this manner, the force between the guide member 32 and the transmission member 31 can be more uniform, and the guide member 32 can be ensured to move more stably relative to the transmission member 31 along the first direction X, so as to better resist external impacts, thereby helping to improve the reliability of the camera lifting device 100.

[0067] Please continue reading Figure 5 According to one aspect of the embodiment of the present application, one of the decorative ring 22 and the lifting ring 21 is provided with a tooth portion 211, and the other is connected to one end of the first buffer member 41 along the first direction X. The tooth 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 tooth portion 211.

[0068] The tooth portion 211 can be understood as a structure having alternately distributed recesses and protrusions in the circumferential direction Y. Under normal operating conditions, one end of the first buffer member 41 along the first direction X can be set in the recess 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] Among them, the length dimensions of the concave portion and the convex portion along the circumferential direction Y can be the same or different, that is, in the circumferential direction Y, the spacing between two adjacent concave portions can be the same or different, and correspondingly, the spacing between two adjacent convex portions can be the same or different.

[0070] Exemplarily, the concave portion and the convex portion are arranged with the same length dimension along the circumferential direction Y.

[0071] The tooth portion 211 extends along the circumferential direction Y of the lifting ring 21 . Optionally, the tooth portion 211 may be a continuous full-ring structure. Of course, it may also be a discontinuous, intermittently arranged ring structure.

[0072] In some embodiments, the decorative ring 22 is provided with a tooth portion 211, one end of the first buffer member 41 along the first direction X is connected to the lifting ring 21, and the other end is movably connected to the tooth portion 211. When the torque applied to the first buffer member 41 is greater than the preset force at which it can be deformed, the first buffer member 41 can provide a force along the circumferential direction Y to the tooth portion 211 to push against the tooth portion 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 a tooth portion 211, one end of the first buffer member 41 along the first direction X is connected to the decorative ring 22, and the other end is movably connected to the tooth portion 211, when the torque applied to the first buffer member 41 is greater than the preset torque at which it can be deformed, the first buffer member 41 can move in the tooth portion 211 to drive the decorative ring 22 to rotate relative to the lifting ring 21.

[0074] Exemplarily, the first buffer member 41 can move from one of the recesses to the adjacent convex portion; or, the first buffer member 41 can move from one of the recesses to another recess, so as to drive the decorative ring 22 to rotate relative to the lifting ring 21 .

[0075] Optionally, the tooth portion 211 may be configured as a toothed groove structure, and the first buffer member 41 may include a toothed structure, and the two may mesh with each other along the axial direction.

[0076] Optionally, the tooth portion 211 may be configured as a rectangular groove structure, that is, along the circumferential direction Y, the orthographic projection of the concave portion and the orthographic projection of the convex portion are both rectangular structures, and the first buffer member 41 may include a spherical structure.

[0077] The camera lifting device 100 provided in some embodiments of the present application is helpful in ensuring the effectiveness of the first buffer member 41 in buffering external impacts.

[0079] It can be understood that the decorative ring 22 is arranged on the side of the lifting ring 21 along the first direction X that is away from the base 10, and one of the decorative ring 22 and the lifting ring 21 can be arranged on the other along the first direction X, so that the tooth portion 211 of the lifting ring 21 can be located on the side of the decorative ring 22 along the first direction X that is away from the base 10.

[0080] By configuring in this manner, the ball 412 can be disposed against the tooth portion 211 under the force of the elastic member 411 , so that the decorative ring 22 and the lifting ring 21 can be more tightly connected under the connection of the first buffer member 41 .

[0081] The first buffer member 41 includes an elastic member 411 and a ball 412 which are connected to each other. Optionally, when the tooth portion 211 is arranged on the decorative ring 22, the elastic member 411 is connected to the lifting ring 21, and the ball 412 is movably connected to the tooth portion 211; when the tooth portion 211 is arranged on the lifting ring 21, the elastic member 411 is connected to the decorative ring 22, and the ball 412 is movably connected to the tooth portion 211.

[0082] like Figure 7 and Figure 8 As shown, when the camera lifting device 100 is in normal operation, the ball 412 abuts against the tooth portion 211. Specifically, the ball 412 extends into the recess, that is, in the circumferential direction Y, the orthographic projection of the ball 412 overlaps with the orthographic projection of the tooth portion 211.

[0083] like Fig. 9 and Fig.10 As shown, when the decorative ring 22 is in an extended state and is subjected to an external impact along an angle inclined to the first direction X, or is subjected to an external rotational impact, the ball 412 can extend from the recessed 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 portion 211.

[0084] In some embodiments, the elastic member 411 can be configured as any one of a spring, rubber and sponge.

[0086] The connecting portion 222 is connected to a side of the ring body 221 along the first direction X toward the lifting ring 21 and protrudes from the ring body 221. The lifting ring 21 has a tooth portion 211 on a side along the first direction X toward the decorative ring 22, wherein the tooth portion 211 can be formed by a depression on a side of the lifting ring 21 along the first direction X that is away from the decorative ring 22. The connecting portion 222 extends between the inner annular surfaces of the tooth portion 211 along the first direction X and is located on a side of the tooth portion 211 along the first direction X toward the base 10.

Figure 5 and Figure 8 As shown, the ring body 221 , the tooth portion 211 , the ball 412 , the elastic member 411 , and the connecting portion 222 are arranged in sequence along the first direction X.

[0088] According to one aspect of the embodiment of the present application, the second buffer member 42 can be extended or shortened along the first direction X, and the second buffer member 42 includes any one of a spring, rubber, and sponge.

[0089] like Figure 6 and Figure 7 As shown, when the camera lifting device 100 is in normal operating conditions, that is, when the torque applied to the second buffer member 42 is less than or equal to the preset torque causing its deformation, the second buffer member 42 located between the guide member 32 and the transmission member 31 is always in a compressed state to be connected between the two, and will not be deformed.

[0090] like Fig.11 As shown, when the decorative ring 22 is in an extended state and is subjected to an external impact along a first direction X, and the torque transmitted to the second buffer member 42 by this impact is greater than the preset torque value at which it can deform, the second buffer member 42 shortens to absorb or even eliminate the impact, thereby reducing or eliminating the impact of the impact on other components; when the external impact disappears, the second buffer member 42 extends to restore the initial compressed state, so that the guide member 32 moves relative to the transmission member 31 along the first direction X back to the base 10 to the initial position.

[0091] The second buffer member 42 can be configured as a spring, rubber, or sponge.

[0092] Exemplarily, the second buffer member 42 is configured as a spring. Specifically, the guide member 32 is provided with a first fixing portion, the first fixing portion is connected to a side of the guide member 32 facing the transmission member 31 along the first direction X and protrudes from the guide member 32, the transmission member 31 is provided with a second fixing portion, the second fixing portion is connected to a side of the transmission member 31 facing the guide member 32 along the first direction X and protrudes from the transmission member 31, the spring is sleeved on the first fixing portion on one side along the first direction X and abuts against the guide member 32, and the other side is sleeved on the second fixing portion and abuts against the transmission member 31.

[0093] Please continue reading Figures 1 to 11 According to one aspect of an embodiment of the present application, the camera lifting device 100 further includes a driving mechanism 50 , which is connected to the base 10 and is configured to drive the transmission member 31 to rotate.

[0094] The driving mechanism 50 is used to drive the transmission member 31 to rotate, so as to realize the lifting and lowering of the lifting mechanism 20. Optionally, the driving mechanism 50 may include but is not limited to one of an electric motor and a motor.

[0095] The camera lifting device 100 provided in some embodiments of the present application is provided with a first buffer member 41 and a second buffer member 42 to absorb or even eliminate the impact force from the outside, thereby preventing the impact force from being transmitted from the decorative ring 22 to the driving mechanism 50 to cause damage to the driving mechanism 50 and making the camera lifting device 100 unable to operate normally, thereby helping to improve the reliability and service life of the driving mechanism 50, thereby helping to improve reliability.

[0096] In some embodiments, a reduction gear 60 is provided between the driving mechanism 50 and the transmission member 31 for transmitting the rotational torque of the driving mechanism 50 to the transmission member 31 .

[0097] The reduction gear 60 has the function of reducing the output speed, increasing the torque and improving the load capacity. By setting the reduction gear 60, a higher torque output can be obtained so that the transmission member 31 can obtain a better rotation effect. Moreover, it can also realize flexible change of the power output direction to meet various work needs.

[0098] In some optional embodiments, the camera lifting device 100 further includes a protective cover 70, and the driving mechanism 50 and the reduction gear 60 are disposed inside the protective cover 70, and the protective cover 70 is used to protect them to ensure safe operation.

[0099] Optionally, the base 10 also includes an adapter plate connected to the seat 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 arranged on the adapter plate, the protective cover and the adapter plate are enclosed to form a protective cavity, and the drive mechanism 50 and the reduction gear 60 are accommodated in the protective cavity.

[0100] Exemplarily, the transmission member 31 is configured as an annular structure, and the outer annular surface is provided with a gear meshing with the reduction gear 60 to receive the drive of the driving mechanism 50 .

[0101] According to one aspect of the embodiment of the present application, the guide member 32 includes a first guide ring 321 and a second guide ring 322 distributed along the first direction X, the 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 also 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 a rotational freedom relative to the second guide ring 322.

[0102] The second buffer member 42 is disposed between the first guide ring 321 and the transmission member 31 . The first guide ring 321 is pressed by the second buffer member 42 to be tightly pressed against the second guide ring 322 through the third buffer member 43 .

[0103] It can be understood that under normal operating conditions, the first guide ring 321 and the second guide ring 322 rotate synchronously and there is no relative rotation; when the driving mechanism 50 is abnormal, that is, it suddenly provides an abnormally large torque to the transmission member 31, the transmission member 31 rotates and drives the first guide ring 321 to rotate, and the torque transmitted by the first guide ring 321 to the third buffer member 43 is greater than the preset torque that the third buffer member 43 can remain stationary relative to the first guide ring 321 and the second guide ring 322, the third buffer member 43 can move relative to the first guide ring 321 and the second guide ring 322, so that the first guide ring 321 and the second guide ring 322 rotate asynchronously, and the third buffer member 43 rotates to prevent the abnormal torque of the first guide ring 321 from being transmitted to the second guide ring 322, so as to absorb or even eliminate the impact of the abnormality of the driving mechanism 50 on other components; when the abnormal torque of the driving mechanism 50 disappears, the relative positions of the first guide ring 321 and the second guide ring 322 are restored.

[0104] By providing the third buffer member 43, the first guide ring 321 can rotate relative to the second guide member 32 so that the two are staggered. Since the third buffer member 43 is connected between the first guide ring 321 and the second guide ring 322, the third buffer member 43 can limit the two, so that even if the two have rotational freedom, they will not be completely misaligned or the gap will become larger.

[0105] Optionally, the third buffer member 43 may include but is not limited to any one of a spherical structure, an ellipsoidal structure, and a polygonal structure.

[0106] According to one aspect of the embodiment of the present application, the number of the third buffer members 43 is set to two or more, and the two or more third buffer members 43 are distributed at intervals along the circumferential direction Y of the lifting ring 21.

[0107] The number of the third buffer members 43 can be two, three, or more, and the specific number can be designed according to the specific structure of the guide member 32 .

[0108] In the embodiment of the present application, the number of the third buffer members 43 may be four, and the four third buffer members 43 are evenly distributed at equal intervals along the circumferential direction Y. By arranging in this manner, 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 be ensured to rotate more stably relative to the first guide ring 321, so as to better resist external impacts, thereby helping to improve the reliability of the camera lifting device 100.

[0109] According to one aspect of an embodiment of the present application, the third buffer member 43 includes a sphere, a first groove 321a is provided on the side of the first guide ring 321 facing the second guide ring 322, and a second groove 322a is provided on the side of the second guide ring 322 facing the first guide ring 321, and the third buffer member 43 abuts between the first groove 321a and the second groove 322a along the first direction X.

[0110] The third buffer member 43 may be in the form of a sphere, which is easy to obtain and helps to reduce costs.

[0111] By arranging the third buffer member 43 along the first direction X between the first groove 321a and the second groove 322a, under normal operation, the rotation of the first guide ring 321 can be transmitted to the second guide ring 322 through the third buffer member 43, so that the two can rotate synchronously.

[0112] According to one aspect of the embodiment of the present application, the volume of the third buffer member 43 is smaller than the sum of the volume of the first groove 321 a and the volume of the second groove 322 a .

[0113] It can be understood that the third buffer member 43 abuts against the first groove 321a and the first groove 321a on both sides along the first direction X, and there is a gap between the third buffer member 43 and the first groove 321a and the first groove 321a on both sides along the circumferential direction Y.

[0114] By configuring in this manner, the space enclosed by the first groove 321a and the second groove 322a can provide freedom of movement for the third buffer member 43. When an abnormality occurs in the driving mechanism 50, the abnormal torque transmitted by the first guide ring 321 can drive the third buffer member 43 to move, so that the abnormal torque cannot be transmitted to the second guide ring 322, thereby improving the reliability of the camera lifting device 100.

[0115] See also Figure 5 According to one aspect of an embodiment of the present application, one of the lifting ring 21 and the second guide ring 322 is arranged in a sleeve on the other, one of the lifting ring 21 and the second guide ring 322 is provided with a sliding portion 3221, and the other is provided with a strip guide portion 212, and the sliding portion 3221 is movably connected to the strip guide portion 212.

[0116] Optionally, the strip guide portion 212 can be set as a slide rail, and the sliding portion 3221 can be set as a slider so as to be able to slide with the slide rail; optionally, the strip guide portion 212 can also be set as a slide groove, and at least part of the sliding portion 3221 extends into the slide groove to slide with the slide groove.

[0118] Specifically, when the decorative ring 22 is in a retracted state, the sliding portion 3221 is located at the second end of the strip guide portion 212; when the decorative ring 22 switches from a retracted state to an extended state, the transmission member 31 drives the second guide ring 322 to rotate, and the sliding portion 3221 moves from the first end to the second end to push the lifting ring 21 to move along a direction back to the base 10, so that the decorative ring 22 is in an extended state.

[0119] Of course, in other embodiments, the lifting ring 21 can 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 guide portion 212; or, the lifting ring 21 can 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 guide portion 212; or, the second guide ring 322 is 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 guide portion 212.

In addition, the structural design can be made more compact, which is beneficial to improving the space utilization of the camera lifting device 100.

[0121] According to one aspect of the embodiment of the present application, the extending direction of the strip-shaped guiding portion 212 is arranged to intersect with the first direction X.

[0122] In some embodiments, a portion of the strip-shaped guiding portion 212 extends along the circumferential direction Y, and an extending direction of another portion of the strip-shaped guiding portion 212 intersects both the circumferential direction Y and the first direction X.

[0128] The lifting ring 21 can cooperate with the first limiting portion 121 to move in the first direction X. The first limiting portion 121 extends along the first direction X. This arrangement is conducive to ensuring 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 to be able to extend and retract along the first direction X.

[0132] Exemplarily, the number of the limit members 12 is set to two, and the two limit members 12 are evenly distributed at equal intervals along the circumferential direction Y, which is beneficial to cost saving, and is also beneficial to improving the stability of the lifting ring 21 relative to its movement, and is beneficial to improving the limiting effect of the limit member 12 on the guide member 32 along the first direction X, which is beneficial to improving the reliability of the camera lifting device 100.
