Detailed Description

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

In the related art, with the development of a camera device on an electronic device, an optical function of the camera becomes strong, which causes the volume of the camera device to become large, and the appearance of the electronic device is severely protruded, thereby affecting the appearance refinement of the electronic device. By arranging the camera device in a lifting structure, the camera device can have larger optical available space when shooting; the camera device can be smaller in size when shooting is not needed, so that influence on the appearance of the electronic equipment is reduced.

However, after the camera stretches out of the electronic device, the camera may be impacted by external force, which easily causes the lifting structure in the camera device to be blocked or stuck, and even causes the lifting structure and the camera to be damaged, thereby shortening the service life of the camera device and causing the damage of the camera device and the electronic device.

Based on the above-mentioned problems, the embodiment of the application provides a camera device and an electronic device, where the camera device may include a carrier, a driving assembly, a camera assembly, a rotating drum, a lifting drum and a first buffer member, where the driving assembly and the rotating drum are both mounted on the carrier, and the driving assembly is matched with the rotating drum to drive the rotating drum to rotate on the carrier. The rotary cylinder and the lifting cylinder are mutually sleeved, and the rotary cylinder is used for driving the lifting cylinder to lift in the rotating process, and the lifting cylinder drives the camera component to lift. The distance between the one end of the lifting cylinder far away from the bearing piece and the bearing piece is smaller than the distance between the one end of the camera assembly far away from the bearing piece and the bearing piece, when the camera device receives external force, the external force acts on the camera assembly, so that the camera assembly and the lifting cylinder move relative to each other along the thickness direction of the camera device. One end of the first buffer piece is connected with one of the lifting cylinder and the camera assembly, and the other end of the first buffer piece is connected with the other of the lifting cylinder and the camera assembly. When the camera device receives external force, the camera subassembly moves towards the carrier, and the first bolster of camera subassembly compression can cushion the external force that receives on the camera subassembly to play the guard action to the camera subassembly, in order to protect camera device and electronic equipment.

Based on the above description, in the embodiments of the present application, a scenario in which a rear camera device is disposed in a mobile phone is taken as an example, and in other examples, the rear camera device may also be used as a front camera device.

As shown in fig. 2 and 3, the rear cover 120, the middle frame 130 and the display screen 110 enclose a receiving space, and at least a portion of the camera device 200 is located in the receiving space, so as to reduce the volume of the camera device 200 protruding outside the mobile phone and reduce the influence of the camera device 200 on the appearance of the mobile phone. For example, the camera device 200 may be partially located in the accommodating space, or the camera device 200 may be entirely located in the accommodating space. The embodiment of the application is described taking the example that the camera device 200 is completely accommodated in the accommodating space.

With continued reference to fig. 3, the rear cover 120 is provided with a mounting hole 121, and the mounting hole 121 may be located at an edge position of the rear cover 120 or at a middle position of the rear cover 120. The camera device 200 is located in the accommodating space enclosed by the rear cover 120, the frame 131 and the display screen 110, and lights through the mounting hole 121. The back cover 120 and the camera device 200 can be sealed by foam or back glue to ensure the tightness of the mobile phone. In other examples, the mounting holes 121 may also be located on either side of the bezel 131 or at corners of the bezel 131.

The following describes the camera device 200 provided in the embodiment of the present application in detail.

As shown in fig. 4 and 5, the camera device 200 may include a carrier 210, a driving assembly 280, and a camera assembly, both of which are mounted on the carrier 210. The driving assembly 280 is used to drive the camera assembly up and down, so that the camera assembly extends and retracts into the electronic device 100.

It should be noted that, as shown in fig. 2, the mobile phone may include a first direction X, where the first direction X may be a width direction of the mobile phone; the mobile phone may include a second direction Y, which may be a length direction of the mobile phone; the cell phone may include a third direction Z, which may be a thickness direction of the cell phone. The direction of the mobile phone may be the same as the directions of the camera device 200, the driving assembly 280, the camera assembly, and the like.

The lifting direction of the camera assembly may include, but is not limited to, a first direction X (X direction), a second direction Y (Y direction), or a third direction Z (Z direction). The embodiment of the application is described by taking the Z direction as the lifting direction of the camera component as an example. For example, when the camera device 200 shoots, the camera assembly moves in a direction away from the display screen 110, thereby extending the electronic apparatus 100; when the camera device 200 does not need to take a picture, the camera assembly moves toward the display screen 110, thereby retracting the electronic apparatus 100.

The drive assembly 280 may include, but is not limited to, electric, pneumatic, hydraulic, worm drive, gear drive, electromagnetic drive, electro-hydraulic drive, gas-liquid drive, electro-magnetic-hydraulic drive, etc. to drive the camera assembly to reciprocate in the Z-direction.

As shown in fig. 5, the camera module may include a camera module 220 and a mounting member 250, the camera module 220 is mounted on the mounting member 250, and the mounting member 250 may prevent an external force or a driving force of the driving assembly 280 from directly acting on the camera module 220, thereby protecting the camera module 220. The driving assembly 280 is used for driving the mounting member 250 to move along the Z direction, and the mounting member 250 drives the camera module 220 to move, so that the camera module 220 extends and retracts into the electronic device 100; of course, the mounting member 250 may not be provided, so that the structure of the camera device 200 is simpler. Wherein, the distance between the end of the mounting member 250 facing away from the carrier 210 and the carrier 210 is greater than the distance between the end of the camera module 220 facing away from the carrier 210 and the carrier 210. Thus, when the camera module extends out of the electronic device 100, the external force will first act on the mounting member 250, instead of the camera module 220, so as to protect the camera module 220.

As shown in fig. 5, the camera module 220 may include a lens 221, the lens 221 may include a barrel and a plurality of lenses located within the barrel, and the lenses may be at least one of Plastic lenses (plastics) and Glass lenses (glasses).

The lens 221 may include a 5P lens (5 lenses), a 6P lens, etc. (6 lenses) according to the number of lenses. For example, the 5P lens may be 5 plastic lenses, or may be 4 plastic lenses and 1 glass lens; the 6P lens can be 6 plastic lenses, 5 plastic lenses and 1 glass lens. The number of lenses in the lens 221 is not limited to 5 or 6, and may be any number of 2 or more.

The camera module 220 may include a focusing motor 222, the focusing motor 222 is located on a side of the lens 221 facing the carrier 210, and the focusing motor 222 is used for adjusting a focal length.

As shown in fig. 6, the driving assembly 280 and the camera assembly may be located at the same side of the carrier 210, so that the driving assembly 280 and the camera assembly may have an overlapping portion in a thickness direction to reduce the overall thickness of the camera device 200. The driving assembly 280 may be located at the outer side of the rotation cylinder 230, thereby enabling the rotation cylinder 230 to be small in size, which is advantageous for miniaturization of the camera device 200. Of course, the drive assembly 280 may be located inside the rotating cylinder 230, thereby protecting the drive assembly 280. The embodiment of the present application is described taking the example that the driving unit 280 is located at the outer side of the rotary cylinder 230.

In some embodiments, as shown in fig. 5 and 6, the carrier 210 may include a substrate 219, and the substrate 219 may be used to carry other structural components, which may be protected, so as to advantageously enhance the overall mechanical strength of the camera device 200.

The carrier 210 may include a sub-circuit board 211, where the sub-circuit board 211 is located on a side of the substrate 219 facing the driving assembly 280 and the camera module 220, and the driving assembly 280 is electrically connected to the sub-circuit board 211 to power the driving assembly 280. The substrate 219 protects the sub-circuit board 211.

The sub-circuit board 211 may be a flexible circuit board (Flexible Printed Circuit, FPC), and the photosensitive element 218 is electrically connected to the sub-circuit board 211.

By way of example, the photosensitive element 218 may be a charge coupled device (charge coupled device, CCD) or a complementary metal oxide semiconductor (complementary metal-oxide-semiconductor, CMOS) phototransistor.

As shown in fig. 5, the carrier 210 may include a base 212, the base 212 is located on a side of the sub-circuit board 211 facing away from the substrate 219, and a hollow area 214 may be disposed on the base 212, where the hollow area 214 is covered with a filter 217. The photosensitive element 218 is disposed opposite to the filter 217 in the Z direction.

Illustratively, the filter 217 may be an infrared filter, and the filter 217 may filter out infrared light to prevent the infrared light from affecting imaging.

Specifically, the sub-circuit board 211 is electrically connected to an image processing unit (Image Signal Processing, ISP) on the main circuit board 140, and the image processing unit (ISP) is electrically connected to a digital processing unit (Digital Signal Processing, DSP). The image processing unit (ISP) and the digital processing unit (DSP) may be separately provided on the main circuit board 140, or the image processing unit (ISP) and the digital processing unit (DSP) may be integrally provided on the main circuit board 140. For example, when photographing, the shutter is opened, light is transmitted to the photosensitive element 218 through the lens 221 and the optical filter 217, the optical signal is converted into an electrical signal, the electrical signal is transmitted to the ISP through the sub-circuit board 211 by the photosensitive element 218 for processing, the electrical signal is converted into a digital image signal by the ISP, the digital image signal is output to the DSP for processing, and the digital image signal is converted into an image signal in a standard RGB, YUV or the like format by the DSP.

The following description is given of the movement of the camera module 220 along the Z direction according to the embodiment of the present application.

It will be appreciated that as shown in fig. 6 and 7, the camera device 200 may include a retracted state in which the camera module 220 does not extend out of the camera device 200, and the camera module 220 is located inside the electronic apparatus 100. At this time, the thickness of the camera device 200 is smaller, the overall thickness of the electronic apparatus 100 is lower, and the influence of the camera device 200 on the appearance of the electronic apparatus 100 is smaller.

As shown in fig. 8 and 9, the camera device 200 may include an extended state in which the camera module 220 is extended from the rear cover 120 in the Z direction toward a direction away from the display screen 110, and the camera module 220 is moved toward a direction away from the carrier 210. At this time, the thickness of the camera device 200 increases, the optically usable space thereof is large, and a good photographing quality can be obtained. The thickness of the camera device 200 is not limited by the thickness of the electronic apparatus 100 any more, and the thickness of the electronic apparatus 100 can be set smaller, which is advantageous for the light and thin electronic apparatus 100.

Of course, the camera device 200 may also be in any state between the extended state and the retracted state.

As shown in fig. 6, the camera device 200 may include a rotation cylinder 230 and a lifting cylinder 240, and the rotation cylinder 230 and the lifting cylinder 240 may be substantially cylindrical. The camera module 220 is located at the inner sides of the rotation cylinder 230 and the elevation cylinder 240, and at least a part of the mounting member 250 is located at the inner sides of the rotation cylinder 230 and the elevation cylinder 240 for mounting the camera module 220, so that the volume of the camera device 200 can be reduced; in addition, the camera module 220 can be protected.

The rotating cylinder 230 is used for driving the lifting cylinder 240 to lift during the rotation process, for example, the rotating cylinder 230 and the lifting cylinder 240 are sleeved with each other and are in threaded connection. The driving assembly 280 drives the rotary cylinder 230 to rotate, the lifting cylinder 240 does not rotate in the XY plane, and the threads on the rotary cylinder 230 and the threads on the lifting cylinder 240 move relatively, so that the lifting cylinder 240 is driven to move along the Z direction, the lifting cylinder 240 drives the mounting piece 250 to move along the Z direction, and the mounting piece 250 drives the camera module 220 to move along the Z direction.

Because the surface areas of the lifting cylinder 240 and the rotating cylinder 230 are larger, the threaded areas arranged on the lifting cylinder 240 and the rotating cylinder 230 are larger, so that the threaded connection area between the lifting cylinder 240 and the rotating cylinder 230 is larger, the connection stability of the lifting cylinder 240 and the rotating cylinder 230 is higher, and the stability of the rotating cylinder 230 for driving the lifting cylinder 240 to move through threads is higher.

With continued reference to fig. 5, the rotary cylinder 230 is rotatably disposed on the carrier 210, for example, the rotary cylinder 230 may be disposed on a surface of the base 212 facing away from the substrate 219, a slide 213 is disposed on a side of the base 212 facing the rotary cylinder 230, the slide 213 may be an annular slide, and an end of the rotary cylinder 230 near the base 212 is accommodated in the slide 213 and is driven by the driving assembly 280 to rotate along the slide 213.

The positional relationship of the rotary cylinder 230, the lifting cylinder 240, and the mounting member 250 provided in the embodiment of the present application is explained below.

As shown in fig. 10 and 11, the lifting cylinder 240 may be sleeved on the inner side of the rotating cylinder 230, and the mounting member 250 may be positioned on the inner side of the lifting cylinder 240. At this time, the outer wall surface of the lifting cylinder 240 is provided with a first external screw thread 241, the inner wall surface of the rotation cylinder 230 is provided with a first internal screw thread 231, the first internal screw thread 231 is screw-coupled with the first external screw thread 241, and the rotation cylinder 230 is screw-coupled with the lifting cylinder 240 through the first external screw thread 241 and the first internal screw thread 231. Because the driving assembly 280 is located outside the rotation cylinder 230, the driving assembly 280 and the first internal thread 231 do not interfere with each other, so that the first internal thread 231 can be set longer along the Z direction, and the movement stroke of the lifting cylinder 240 along the Z direction is longer, so that the movement stroke of the camera module 220 is longer.

As illustrated in fig. 7 and 11, the mounting member 250 includes a first mounting portion 251 and a second mounting portion 252 connected to each other, and the second mounting portion 252 is located on a side of the first mounting portion 251 facing away from the carrier 210. The first mounting portion 251 is used for mounting the camera module 220, and the second mounting portion 252 at least partially surrounds the outside of the camera module 220 to protect the camera module 220. In addition, the distance between the end of the second mounting portion 252 far from the carrier 210 and the carrier 210 is greater than the distance between the end of the camera module 220 far from the carrier 210 and the carrier 210, so that the second mounting portion 252 is convenient to be connected with external structural components.

In some examples, the camera module 220 may be disposed on a side of the first mounting portion 251 facing away from the carrier 210. In other examples, a second buffer 272 may be disposed between the side of the first mounting portion 251 facing away from the carrier 210 and the camera module 220, where the second buffer 272 is located between the focus motor 222 and the first mounting portion 251. Thus, when the camera module 220 is impacted by external force, the interaction force between the camera module 220 and the first mounting portion 251 can be reduced, so as to protect the camera module 220. The first mounting portion 251 and the second mounting portion 252 may be connected by bonding, welding, clamping, or integrally molding.

By way of example, second cushioning member 272 may comprise any one or more of rubber, foam, sponge, latex, silicone, and metal elastomer.

As shown in fig. 12 and 13, the lifting cylinder 240 may be sleeved outside the rotating cylinder 230, with a part of the mounting member 250 being located outside the lifting cylinder 240, and a part of the mounting member 250 being located inside the lifting cylinder 240. At this time, the outer wall surface of the rotating cylinder 230 is provided with the second external screw thread 232, the inner wall surface of the lifting cylinder 240 is provided with the second internal screw thread 242, the second internal screw thread 242 is screwed with the second external screw thread 232, and the rotating cylinder 230 and the lifting cylinder 240 are screwed with the second internal screw thread 242 through the second external screw thread 232.

For example, with continued reference to fig. 12, the mount 250 may include an outer mounting portion 253 and an inner mounting portion 254 connected, the outer mounting portion 253 being located outside of the lift cylinder 240, the inner mounting portion 254 being located inside of the rotation cylinder 230, the inner mounting portion 254 being for mounting the camera module 220. A second buffer member 272 may also be disposed between the inner mounting portion 254 and the camera module 220, and the principle thereof will not be described again. Wherein the outer mounting portion 253 and the inner mounting portion 254 may be connected by a connection portion 255. The outer mounting portion 253 and the connecting portion 255, and the inner mounting portion 254 and the connecting portion 255 may be connected by bonding, welding, fastening, or integrally molding.

At least one of the inner and outer mounting portions 254 and 253 is spaced apart from the carrier 210 by a distance greater than a distance between an end of the camera module 220 spaced apart from the carrier 210 and the carrier 210, so that the mounting member 250 is connected to an external structural member.

As shown in fig. 5 and 7, the camera device 200 may include a guide 215, the guide 215 being located at a side of the carrier 210 facing the camera module 220, the guide 215 being connected to the carrier 210. The connection between the guide 215 and the carrier 210 may be any one or more of the guide 215, the sub-circuit board 211, the substrate 219, and the base 212, and other structural components in the embodiment of the present application are connected to and similar to the carrier 210, which is not described herein.

Illustratively, the guide 215 may be coupled to the base 212 such that the guide 215 does not interfere with the sub-circuit board 211. The guide 215 and the base 212 may be connected by bonding, welding, clamping, integrally forming, screwing, etc.

Wherein the guide 215 extends in the Z direction, and the guide 215 is inserted into at least one of the elevation cylinder 240 and the mount 250. For example, the guide 215 may be inserted in the elevation cylinder 240, or the guide 215 may be inserted in the mount 250, or the guide 215 may be inserted in both the elevation cylinder 240 and the mount 250. The guide 215 serves to prevent the elevation cylinder 240 from rotating in the XY plane, so that the elevation cylinder 240 can be driven to move in the Z direction by the rotation of the rotation cylinder 230, and in addition, the guide 215 can play a guiding role in the moving direction of the elevation cylinder 240 so that the elevation cylinder 240 moves in the extending direction of the guide 215, i.e., in the Z direction.

It will be appreciated that the rotation of the lift cylinder 240 may be directly limited when the guide 215 is inserted in the lift cylinder 240. When the guide 215 is inserted in the mount 250 and the rotation of the elevation cylinder 240 is restricted by the mount 250, a limit assembly needs to be provided between the mount 250 and the elevation cylinder 240 to limit the mutual rotation between the mount 250 and the elevation cylinder 240 in the XY plane, thereby restricting the rotation of the elevation cylinder 240 by the guide 215.

Illustratively, the guide 215 includes at least one, and when the number of the guide 215 is 1, the number of the guide 215 is small, and the structure of the camera device 200 is simple.

Illustratively, when the number of the guide members 215 is plural, the plurality of guide members 215 are disposed at intervals along the circumferential direction of the rotary cylinder 230, and each guide member 215 is uniformly stressed and is not easily damaged. The guide 215 may include 2, 3, 4, or 5 or more. The plurality of guide members 215 may be axisymmetrically distributed and centrosymmetrically distributed, so that the stress uniformity of the guide members 215 may be further improved; alternatively, the plurality of guides 215 may be asymmetrically distributed, etc.

The embodiment of the present application will be described by taking the guide 215 as an example to be inserted into the mounting member 250.

As shown in fig. 14 and 15, the mounting member 250 is provided with a guide groove 256, and the guide member 215 is at least partially inserted into the guide groove 256, and the guide member 215 can move in the Z direction in the guide groove 256 to guide the movement direction of the mounting member 250. The guide 215 guides the movement of the lifting cylinder 240 in the Z direction by the mounting member 250 due to the spacing assembly provided between the mounting member 250 and the lifting cylinder 240. The guide groove 256 may be located on a side of the mounting member 250 facing away from the lift cylinder 240, or the guide groove 256 may be located on a side of the mounting member 250 facing toward the lift cylinder 240. In other examples, a guide hole may be provided in the mounting member 250, the guide hole extending through the mounting member 250 in the Z direction, the guide member 215 being positioned in the guide hole, the guide member 215 being movable in the Z direction in the guide hole. In other examples, guide slots 256 or guide holes may also be provided in the lift cylinder 240, enabling more scenarios to be applicable.

In some embodiments, as shown in fig. 7, an end of the guide 215 remote from the carrier 210 is provided with a stopper 216, and the stopper 216 is used to prevent at least one of the lift cylinder 240 and the mount 250 from being separated from the carrier 210. At least one of the projections of the lift cylinder 240 and the mount 250 on the carrier 210 partially overlaps with the projection of the stopper 216 on the carrier 210. Illustratively, the projection of the stop 216 on the carrier 210 overlaps with the projection of the lifting cylinder 240 on the carrier 210, the stop 216 stops the lifting cylinder 240 on the side of the overlapping portion facing away from the carrier 210, the stop 216 can prevent the lifting cylinder 240 from separating from the carrier 210, and the stop 216 can control the movement stroke of the lifting cylinder 240. In other examples, the projection of the stop 216 on the carrier 210 overlaps with the projection of the mounting member 250 on the carrier 210, the stop 216 stops a side of the mounting member 250 disposed at the overlapping portion facing away from the carrier 210, the stop 216 can prevent the mounting member 250 from separating from the carrier 210, and the stop 216 can control the movement stroke of the mounting member 250. For example, the stop 216 may be glued, welded, snapped, integrally attached to the guide 215.

In some embodiments, as shown in fig. 5, the camera device 200 may include a protective cover 292, where the protective cover 292 may be connected to an end of the mounting member 250 away from the carrier 210, and an edge of the protective cover 292 extends toward the carrier 210 to be disposed around the outer circumferences of the rotating cylinder 230, the mounting member 250 and the lifting cylinder 240. The protective cover 292 protects the structural components located inside the protective cover 292.

The middle region of the protective cover 292 may be provided with a light transmission hole 293, where the light transmission hole 293 is covered with a light transmission member 294, and the lens 221 and the light transmission member 294 are disposed opposite to each other along the Z direction. Thus, at the time of photographing, external light may enter the lens 221 through the light transmitting member 294. The light-transmitting member 294 may be attached to the protective cover 292 by means of a snap fit, adhesive, threaded connection, or the like.

For example, as shown in fig. 5, a sealing member 291 may be disposed between the light-transmitting member 294 and the protective cover 292, the sealing member 291 may be annular, and the sealing member 291 is used for sealing between the protective cover 292 and the light-transmitting member 294, so as to protect the camera module 220. In other examples, the seal 291 may have both sealing and bonding functions.

In this embodiment, as shown in fig. 9, the camera device 200 may include a first buffer member 271 for buffering the external impact force applied to the camera module 220, so as to protect the camera module 220.

By way of example, the first buffer 271 may comprise a spring, which is simple in structure and low in cost.

As shown in fig. 9, the camera device 200 may include a buffering state, that is, a state in which the first buffer 271 is compressed to release the external force when the camera module 220 is impacted by the external force F after the camera module 220 extends out of the electronic apparatus 100.

The arrangement of the first buffer 271 provided in the embodiment of the present application will be described in detail below.

It should be noted that, when the driving assembly 280 drives the lifting cylinder 240 to lift, the mounting member 250 may move along the Z direction under the driving of the lifting cylinder 240, and both move in the same direction. In addition, under the action of the external force F (fig. 9), the mounting member 250 and the lifting cylinder 240 can also move relative to each other along the Z direction. The first buffer member 271 is disposed between the elevation cylinder 240 and the mount member 250, and the elevation cylinder 240 and the mount member 250 receive a buffer force of the first buffer member 271 during a mutual movement in the Z direction, thereby releasing an external force received by the mount member 250 through the first buffer member 271. Because the mounting member 250, the camera module 220 and the protective cover 292 are connected, the mounting member 250, the camera module 220 and the protective cover 292 can be regarded as a single structure, and when the single structure is acted by an external force, the single structure moves towards the carrier 210 and compresses the first buffer member 271, thereby buffering the external force on the single structure and protecting the single structure. The stress and movement conditions of the overall structure are the same as those of the mounting member 250, and for convenience of description, the embodiment of the present application will be described by taking the movement and stress conditions of the mounting member 250 as an example.

Specifically, as shown in fig. 9, the external force F acts on the protective cover 292, and then is transmitted to the mounting member 250, the first buffer member 271, the lifting cylinder 240, the rotating cylinder 230, and the carrier 210, and the first buffer member 271 is compressed by the mounting member 250 and the lifting cylinder 240 to buffer the external force. The camera module 220 and the protective cover 292 may have a gap therebetween, so that an interaction force between the protective cover 292 and the camera module 220 may be avoided, and the camera module 220 is protected.

As shown in fig. 8 and 9, the distance between the end of the lifting cylinder 240 far from the carrier 210 and the carrier 210 is smaller than the distance between the end of the camera assembly far from the carrier 210 and the carrier 210, so that when the camera device 200 is subjected to an external force, the external force acts on the camera assembly first, rather than acting on the lifting cylinder 240, so that the screw structure between the lifting cylinder 240 and the rotating cylinder 230 can be protected. In addition, space can be provided for movement of the camera assembly toward the carrier 210 such that the camera assembly and the lift cylinder 240 move relative to each other in the Z-direction. The first buffer 271 is used for buffering when the camera head assembly moves toward the carrier 210. One end of the first buffer member 271 is connected with one of the lifting cylinder 240 and the camera assembly, and the other end of the first buffer member 271 is connected with the other of the lifting cylinder 240 and the camera assembly, so that when the camera assembly moves toward the carrier 210, the first buffer member 271 between the lifting cylinder 240 and the camera assembly is compressed, thereby realizing a buffer effect to protect the camera assembly, thereby protecting the camera device 200 and the electronic apparatus 100, and prolonging the service time of the camera device 200 and the electronic apparatus 100.

For example, the distance between the end of the lifting cylinder 240 away from the carrier 210 and the carrier 210 is smaller than the distance between the end of the mounting member 250 away from the carrier 210 and the carrier 210, so that the camera assembly is subjected to an external force, which acts on the mounting member 250 first, instead of the lifting cylinder 240. The protective cover 292 may be connected to an end of the second mounting portion 252 (fig. 14) of the mounting member 250 remote from the carrier 210, or the protective cover 292 may be connected to an end of at least one of the outer and inner mounting portions 253, 254 (fig. 13) of the mounting member 250 remote from the carrier 210, thereby enabling space for movement of the mounting member 250 toward the carrier 210.

Specifically, the lifting cylinder 240 and the mounting member 250 are respectively pressed at different positions of the first buffer member 271, the pressing positions of the mounting member 250 and the first buffer member 271 may be a first pressing position, the pressing positions of the lifting cylinder 240 and the first buffer member 271 may be a second pressing position, and the first pressing position is located at a side of the second pressing position away from the carrier 210. That is, at least a portion of the first buffer member 271 is located between the first pressing position and the second pressing position to be able to compress the portion of the first buffer member 271 between the first pressing position and the second pressing position when the mounting member 250 moves toward the carrier 210 by the external force, thereby buffering the external force.

The mounting member 250 may be pressed against the middle section of the first buffer member 271 along the Z direction, or may be pressed against an end of the first buffer member 271 away from the carrier 210. The lifting cylinder 240 may be pressed to the middle section of the first buffer 271 in the Z direction, or may be pressed to an end of the first buffer 271 near the carrier 210.

In the embodiment of the application, the mounting member 250 is pressed at the end of the first buffer member 271 away from the carrier 210, and the lifting cylinder 240 is pressed at the end of the first buffer member 271 near the carrier 210. At this time, the first buffer 271 between the first pressing position and the second pressing position is long, and the external force can be well buffered.

It should be noted that, when the camera device 200 is in the retracted state, the first buffer member 271 may be in a compressed state or an initial state without deformation, so that the first buffer member 271 may have a better buffering effect. When the camera device 200 is in the retracted state, if the first buffer member 271 is in the compressed state, the first buffer member 271 is also in the compressed state in other states, i.e. the first buffer member 271 is always in the compressed state, and the first buffer member 271 can support the mounting member 250, so that the lifting cylinder 240 drives the mounting member 250 to extend out of the electronic device 100 through the first buffer member 271. When the camera device 200 is in the retracted state, if the first buffer member 271 is in an initial state without deformation, the first buffer member 271 needs to be compressed before the lifting cylinder 240 drives the mounting member 250 to extend out of the electronic device 100, so as to provide a supporting force for the mounting member 250, thereby driving the mounting member 250 to extend out of the electronic device 100 through the compressed first buffer member 271.

In the embodiment of the present application, as long as the camera module 220 extends out of the electronic device 100, whether the camera module 220 extends out or retracts inward, or in a normal working state, the first buffer member 271 can play a role in buffering, and the first buffer member 271 can realize the whole-course buffering of the movement process and the working process of the camera module 220, so that the protection effect on the camera module 220 is better.

In the present embodiment, the first buffer 271 may be mounted to at least one of the lift cylinder 240 and the mount 250.

In some examples, as shown in fig. 11 and 13, a first buffer 271 may be provided in the lift cylinder 240. In other examples, as shown in fig. 10 and 12, the first buffer member 271 may be further provided in the mount 250, so that the first buffer member 271 may be provided longer in the Z direction, and the buffer effect of the first buffer member 271 is better. In other examples, different first buffers 271 may also be provided in the lift cylinder 240 and the mount 250, respectively, to meet different demands on the first buffers 271.

As illustrated in fig. 16 and 17, the first buffer member 271 may include at least one, and when the first buffer member 271 is one, the number of the first buffer members 271 is small, and the structure of the camera device 200 is simple. When the number of the first buffer members 271 is plural, the plural first buffer members 271 are distributed at intervals along the circumferential direction of the lifting cylinder 240 or the mounting member 250, and the number of the first buffer members 271 is large, so that a good buffer effect is achieved.

The number of the first buffers 271 may include, but is not limited to, 2, 3, 4, 5, or 6 and more. As shown in fig. 16, the first buffer members 271 may be axisymmetric or centrosymmetrically distributed, so that the stress of each first buffer member 271 is relatively uniform, and the buffering effect of the first buffer member 271 is relatively uniform. Alternatively, the first buffer 271 may be asymmetrically distributed.

The embodiment of the present application will be described taking the example in which the first buffer member 271 is provided in the mount 250.

As shown in fig. 14, the mounting member 250 is provided therein with a fitting area for mounting the first buffer member 271. For example, at the fitting region, one end of the mounting member 250 away from the carrier 210 and one end of the mounting member 250 close to the carrier 210 are respectively pressed against opposite ends of the first buffer member 271 in the Z direction, thereby restricting the first buffer member 271 in the fitting region.

At the assembly area, the mount 250 may include a first gland 261 and a first fitting 263. As shown in fig. 10 and 14, when the elevation cylinder 240 is positioned inside the rotation cylinder 230, the assembly region, the first pressing cover 261, the first fitting 263 and the first buffer 271 are positioned inside the rotation cylinder 230, the first fitting 263 may be disposed on the first mounting part 251, and the mounting member 250 is pressed onto the first buffer 271 sequentially through the first mounting part 251, the first fitting 263 and the first pressing cover 261. As shown in fig. 12, when the lifting cylinder 240 is positioned at the outer side of the rotary cylinder 230, the fitting region, the first pressing cover 261, the first fitting 263 and the first buffer 271 are all positioned at the outer side of the rotary cylinder 230, the first fitting 263 may be disposed at the outer mounting portion 253, and the mounting member 250 is pressed onto the first buffer 271 sequentially through the outer mounting portion 253, the first fitting 263 and the first pressing cover 261.

Wherein the first gland 261 is connected to an end of the first fitting 263 facing away from the carrier 210. The first pressing cover 261 serves to prevent the first buffer 271 from being separated from the first fitting 263 in the Z direction, and in addition, by providing the first pressing cover 261 as a separate member, the first buffer 271 is facilitated to be installed in the fitting area. The first fitting 263 serves to restrict the movement of the first buffer 271 in the XY plane, and the first fitting 263 extends in the Z direction, thereby guiding the movement of the first buffer 271 in the Z direction. The first fitting 263 and the first mounting portion 251 (or the outer mounting portion 253) may be connected by clamping, bonding, welding, screwing, or integrally molding. The first gland 261 and the first fitting 263 may be connected by clamping, bonding, welding, screwing, or integrally forming.

So arranged, as shown in fig. 10 and 12, the mounting member 250 is pressed at an end of the first buffer member 271 away from the carrier 210 by the first pressing cover 261, and the lifting cylinder 240 is provided with a first pressing member 265 (fig. 18) at an end facing the carrier 210, and the first pressing member 265 may be pressed at an end of the first buffer member 271 facing the carrier 210. The first pressing member 265 may be abutted against, directly connected to, or connected to the first buffer member 271 through a connection structure on the first buffer member 271. The first gland 261 and the first buffer 271 may abut, be directly connected, or be connected by a connection structure on the first buffer 271.

For example, as shown in fig. 10, the first fitting 263 may be a fitting cylinder that is sleeved outside the first buffer 271. A notch may be provided at a side of the assembly drum facing the lifting drum 240, and the first pressing member 265 may extend into the assembly drum through the notch and be pressed at an end of the first buffer member 271 facing the carrier 210. The notch may be a bar-shaped notch and extend in the Z direction so that the first pressing member 265 may reciprocate in the notch in the Z direction, thereby achieving a mutual movement between the lifting cylinder 240 and the mounting member 250 in the Z direction.

For example, the first fitting 263 may be a fitting post, and the first buffer 271 may be sleeved outside the fitting post. The first pressing member 265 is pressed at an end of the first buffer member 271 facing the carrier 210, and the first pressing member 265 is in clearance fit with the assembly column, so that the first pressing member 265 can reciprocate along the assembly column.

The distance between the end of the first pressing cover 261, which is far from the carrier 210, and the carrier 210 may be greater than or equal to the distance between the end of the rest of the mounting member 250, which is far from the carrier 210, and the first pressing cover 261 is connected with the protecting cover 292, so that when an external force acts on the camera device 200, the external force acts on the protecting cover 292 and the first pressing cover 261 first, and is transferred to the first buffer 271 through the first pressing cover 261.

When an external force acts, the external force is transmitted to the protective cover 292, the first gland 261, the first buffer member 271 and the first pressing member 265, the mounting member 250 moves toward the carrier 210, and the first pressing member 265 compresses the first buffer member 271 in a direction away from the carrier 210, thereby achieving buffering.

It will be appreciated that the first press 265 may cooperate with any one or more of the first dampener 271 and the first mount 263 to avoid rotation of the lift cylinder 240 and the mount 250 relative to one another in the XY plane, thereby forming a stop assembly between the lift cylinder 240 and the mount 250. Of course, other stop assemblies may be provided between the lift cylinder 240 and the mount 250 to prevent rotation of the lift cylinder 240 and the mount 250 relative to each other.

It can be understood that, as shown in fig. 11 and 13, when the first buffer member 271 is located in the elevation cylinder 240, an assembly area is located in the elevation cylinder 240, and at the assembly area, one end of the elevation cylinder 240 away from the carrier 210 and one end close to the carrier 210 are respectively pressed against opposite ends of the first buffer member 271 in the Z direction. Wherein, at the assembly area, the lifting cylinder 240 may comprise a second gland 262 and a second fitting, the second gland 262 being connected at an end of the second fitting remote from the carrier 210. At this time, the mounting member 250 is provided with a second pressing member 266 along the middle section of the Z direction, the second pressing member 266 is pressed against the end of the first buffer member 271 away from the carrier 210, and the end of the lifting cylinder 240 near the carrier 210 is pressed against the end of the first buffer member 271 near the carrier 210. The second fitting may be a fitting cylinder or a fitting column, and the principle is similar to that of disposing the first buffer member 271 on the mounting member 250, and will not be described again.

When an external force is applied, the external force is transmitted to the protective cover 292, the mounting member 250, the second pressing member 266, the first buffer member 271 and the lifting cylinder 240, the mounting member 250 moves toward the carrier 210, and the second pressing member 266 compresses the first buffer member 271 toward the carrier 210, thereby achieving buffering.
