In this embodiment, the second end of the linkage 13 is provided with a driving rack 131, the driving rack 131 is engaged with the worm gear 14, and the worm gear 14 can drive the linkage 13 to move linearly up and down. When the driver 16 drives the worm wheel 14 to rotate clockwise through the worm 15, the linkage piece 13 is driven by the worm wheel 14 to move upwards, and the elastic piece 17 drives the camera module 11 to move upwards by virtue of elasticity, so that the camera module 11 extends out of the shell 30 through the through hole; when the driver 16 drives the worm wheel 14 to rotate counterclockwise through the worm 15, the linkage 13 is driven by the worm wheel 14 to move down, and the linkage 13 presses against the limiting block 111 and drives the limiting block 111 to move down, so that the camera module 11 retracts into the housing 30 through the through hole.

Further, the camera module lifting device 10 further includes a first detecting element 21, a second detecting element 22 and a controller (not shown), the controller is electrically connected to the first detecting element 21, the second detecting element 22 and the driver 16, the first detecting element 21 is disposed on one side of the camera module 11, the first detecting element 21 is used for detecting a position of the camera module 11 when the camera module 11 extends out, the second detecting element 22 is disposed on an end of the camera module 11 or one side of the camera module 11, the second detecting element 22 is used for detecting a position of the camera module 11 when the camera module 11 retracts, and the controller can control the driver 16 to start or stop according to detection signals of the first detecting element 21 and the second detecting element 22. In this embodiment, the number of the first detecting elements 21 and the second detecting elements 22 can be freely selected according to actual needs, for example, a plurality of first detecting elements 21 can be disposed on the side of the camera module 11 for detecting different moving positions of the camera module 11.

The camera module lifting device 10 of this embodiment supports and leans on stopper 111 through linkage 13, prevent the module 11 of making a video recording to stretch out, when driver 16 orders linkage 13 rebound, elastic component 17 relies on elasticity to order the module 11 of making a video recording to move up and make the module 11 of making a video recording stretch out, fall subaerial from the high altitude when camera module lifting device 10 or electronic equipment, and make a video recording module 11 and ground when bumping, because there is not the auto-lock between linkage 13 and the module 11 of making a video recording, the withdrawal of the module 11 of making a video recording is not influenced by linkage 13, namely the module 11 of making a video recording can freely retract, the module 11 of making a video recording unloads the impact force that the collision produced through the buffering of elastic component 17, the module 11 of making a video recording can retract in casing 30 fast, avoid the direct impact to the module 11 of making a video recording, can effectively avoid the module 11 of making a video recording to damage. Moreover, in the process of collision of the camera module lifting device 10, the second detecting element 22 can rapidly detect the position of the camera module 11 when retracting, at this time, the controller controls the driver 16 to start according to the detection signal, and the driver 16 drives the link 13 to rotate counterclockwise to push the limiting block 111, so that the camera module 11 actively retracts and is in the retracted state.

In addition, in other embodiments, the elastic member 17 may also be a compression spring, the compression spring is disposed at the bottom of the camera module 11 and abuts against the camera module 11, and when the camera module 11 is in the retraction state, the compression spring is in a compressed state, and similarly, the compression spring may also provide an upward elastic force to drive the camera module 11 to move up.

The present application is not limited to the details of the above-described embodiments, and various simple modifications may be made to the technical solution of the present application within the technical idea of the present application, and these simple modifications are all within the protection scope of the present application. The individual features described in the above embodiments may be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described separately in this application.
