Two driving assemblies 280 and two lifting mechanisms 230 are provided, so that the stress of the camera bracket 240 can be uniform, and the stability of the lifting process of the camera device can be improved.

The following describes the up-and-down movement of the camera module 220 along the Z direction according to the embodiment of the present application.

For example, the following describes the raising and lowering process of the camera device with the initial position of the camera device being in the retracted state.

As shown in fig. 7, the camera device is in a retracted state, in which the bottom end of the camera bracket 240 is located on the carrier 210, and the top end of the camera bracket 240 is located within the end surface of the top end of the sealing assembly 270. The driving assembly 280, the lifting mechanism 230, and the camera bracket 240 are disposed on the bearing assembly, and the driving assembly 280, the lifting mechanism 230, and the camera bracket 240 are located on the same side of the bearing member 210. The lifting mechanism 230 comprises a first roller 231 and a second roller 232, wherein the second roller 232 is in transmission connection with the driving assembly 280, and the second roller 232 is in transmission connection with the first roller 231; the second roller 232 is disposed close to the carrier 210, and the distance between the first roller 231 and the carrier 210 is greater than the distance between the second roller 232 and the carrier 210; the first roller 231 is disposed close to the camera bracket 240 and abuts against a guide plate 241 of the camera bracket 240, a friction surface 242 is disposed on a side of the guide plate 241 close to the first roller 231, and the first roller 231 abuts against the friction surface 242.

When the first roller 231 rotates in the first direction, the camera bracket 240 can be driven to move in a direction away from the bearing 210 along the Z direction, so that the camera bracket 240 drives the camera module 220, the light-transmitting member 292, and the protective cover 291 to move in a direction away from the bearing 210, and the camera device reaches the extended state from the retracted state (as shown in fig. 11).

As shown in fig. 11, the camera bracket 240 is in an extended state, that is, the camera device is in an extended state, and at this time, the camera bracket 240, the camera module 220 arranged on the camera bracket 240, the light-transmitting member 292, and the protective cover 291 all extend out of the electronic device. At this time, when the first roller 231 rotates in the second direction, the camera bracket 240 can be driven to move in the direction approaching the bearing 210 along the Z direction, so that the camera bracket 240 drives the camera module 220, the light-transmitting member 292, and the protective cover 291 to move in the direction approaching the bearing 210, and the extended state of the camera device reaches the retracted state.

Note that the camera device achieves the elevation of the camera bracket 240 in the Z direction by means of the rolling friction force between the first roller 231 and the friction surface 242.

It should be noted that the first direction and the second direction are opposite, and illustratively, the first direction is counterclockwise and the second direction is clockwise.

Of course, the rotation directions of the first roller 231 and the second roller 232 may be the same or different, and may be specifically determined according to the winding direction of the transmission device 233; the rotation direction of the driving assembly 280 may be the same as or different from that of the second roller 232, and may be determined according to the connection relationship between the driving assembly 280 and the second roller 232, and is not particularly limited in this embodiment.

It is understood that the second roller 232 can rotate in different directions by controlling the driving assembly 280 to rotate forward and backward, and the rotation of the second roller 232 in different directions can drive the first roller 231 to rotate in different directions, so as to lift the camera bracket 240 in the Z direction. In the present embodiment, the forward rotation may be in a first direction, i.e., counterclockwise, and the reverse rotation may be in a second direction, i.e., clockwise.

In this embodiment, the driving assembly 280 may automatically stop rotating when the camera device reaches the extended state or the retracted state, thereby preventing the camera carriage 240 from falling off the carrier 210. Additionally, the drive assembly 280 may also adjust the camera device to an extended state or a retracted state when the camera device is between the extended state and the retracted state.

The following specifically describes the buffering function of the camera device.

In this embodiment, as shown in fig. 11, when the external force F received by the camera device impacts, the external force F first acts on the light-transmitting member 292, the light-transmitting member 292 is disposed on the protective cover 291 and the camera module 220, and the camera module 220 is disposed on the bracket assembly, so that the external force F received by the camera device impacts on the camera module 220 through the light-transmitting member 292, and then acts on the camera bracket 240 through the camera module 220. Because the first roller 231 and the camera bracket 240 are connected by rolling friction, when the camera bracket 240 is impacted by an external force F, the rolling friction is broken, and the rolling friction becomes sliding friction, so that the camera bracket 240 and the first roller 231 slide, and because the first roller 231 is fixed along the Z-direction, the camera bracket 240 moves along the Z-direction toward the carrier 210, thereby buffering the impact of the external force F on the camera module 220. In addition, in the whole buffering process, no impact is caused on the lifting mechanism 230, so that the problem that the lifting mechanism 230 is damaged due to the impact of an external force F in the related art can be solved.

In the embodiment of the application, the buffering function of the camera can be realized without independently setting a buffering mechanism, the structure of the camera device can be simpler, and the cost of the camera device is further reduced. In addition, as long as camera module 220 will stretch out, is stretching out or has stretched out electronic equipment, no matter be the process that camera module 220 outwards stretched out, still the process of inside withdrawal, or normal operating condition, all can rely on self special construction to realize buffer function to can realize the whole buffering of camera module 220 course of motion and course, it is better to camera module 220's protection effect.

The camera assembly may be automatically returned to the extended state or the retracted state between the extended state and the retracted state by providing a control assembly 260. Because if receive external force impact when the camera device is located the state of stretching out, can make camera bracket 240 drive this camera module 220 to the direction that is close to and holds carrier 210 and slide, the camera device just is located between the state of stretching out and the withdrawal state like this, can influence the normal use of camera device like this, through setting up control assembly 260, when the camera device just is located between the state of stretching out and the withdrawal state, control assembly 260 just can make drive assembly 280 start through monitoring the position of camera bracket 240, and adjust the camera device to the state of stretching out or the withdrawal state, in order to make things convenient for next use.

As shown in fig. 12, the control assembly 260 includes two distance monitoring assemblies 261; wherein, two distance monitoring subassemblies 261 are set up at the interval, and distance h between two distance monitoring subassemblies 261 is the biggest stroke that camera bracket 240 goes up and down along camera bracket 240's axial. By providing two distance monitoring assemblies 261 and setting the distance between the two distance monitoring assemblies 261 to the maximum stroke of the camera carriage 240 in the axial direction of the camera carriage 240, the accuracy of the monitored position of the camera carriage 240 can be improved.
