The lens module 11 includes a housing 111 and two cameras 112 mounted in the housing 111, and the cameras 112 are preferably mounted symmetrically on two sides of the interior of the housing 111, and it is understood that the number of the cameras 112 is not limited to two, and may be one or more.
Preferably, in the present embodiment, the supporting rod 12 is integrally formed with the lens module 11, and the threaded section 121 is integrally formed with the supporting rod 12, so as to ensure the strength of the camera mechanism 10.
It is understood that the lens module 11 and the supporting rod 12 may be assembled separately, and the threaded section 121 and the supporting rod 12 may also be assembled separately.

In practical application, it can be understood that a reduction gearbox may be disposed between the driver 22 and the driving shaft 21, and the reduction gearbox performs speed reduction and torque increase processing on the rotation output of the driver 22, so that the driving shaft 21 can obtain a larger torque.
The bracket 30 is located on one side of the lifting piece 23 away from the lens module 11, the bracket 30 is provided with a second threaded hole 31 and a second through hole 32 in a penetrating manner, the second threaded hole 31 is opposite to and communicated with the first through hole 232, the second through hole 32 is opposite to and communicated with the first threaded hole 231, the second threaded hole 31 is used for being in threaded fit with the threaded section 121, and the driving shaft 21 can movably penetrate through the second through hole 32.
When a user needs to use the photographing function of the electronic device 1, the driver 22 can be controlled to drive the driving shaft 21 to rotate, the lifting piece 23 is driven by the driving shaft 21 to move linearly in a direction away from the bracket 30 and drive the supporting rod 12 and the lens module 11 to move together, so that the lens module 11 is pushed out of the accommodating cavity 203, after the lens module 11 stops moving, the user can use the photographing function of the electronic device 1, when the user needs to photograph photos at different angles, the driving shaft 21 can rotate continuously, after the threaded section 121 and the second threaded hole 31 form threaded fit, the lifting piece 23 can drive the supporting rod 12 to rotate and further drive the lens module 11 to rotate, therefore, the user can photograph photos at different angles without manually rotating the electronic device 1, the use of the user is facilitated, and the operation experience of the user is improved.
After the shooting is completed, the driver 22 can be controlled to drive the driving shaft 21 to rotate reversely, so that the lifting member 23 moves linearly toward the bracket 30 and drives the supporting rod 12 and the lens module 11 to move together, thereby retracting the lens module 11 into the accommodating cavity 203, and reducing the risk that the lens module 11 is exposed to the outside and damaged.
As a modification of this embodiment, an annular groove 233 communicating with the first through hole 232 is formed in the lifting member 23, and a stopper 122 inserted into the annular groove 233 is protruded on the support rod 12.
Through the matching between the annular groove 233 and the stopping portion 122, the lifting member 23 is stopped by the stopping portion 122 during the linear movement, so that the lifting member cannot move relative to the supporting rod 12, and the supporting rod 12 is driven to move together, thereby driving the lens module 11 to move.
It is understood that the stopping portion 122 may be formed together with the supporting rod 12, or may be formed by assembling separately, and it is also possible to provide the stopping portion 122 on the hole wall of the first through hole 232 and provide the annular groove 233 on the supporting rod 12 to limit the movement of the supporting rod 12 in the axial direction.

Referring to fig. 3-7, the process of pushing out, rotating and retracting the lens module 11 will be described in detail.
The electronic device 1 receives the first control instruction and sends a first execution instruction to the driving mechanism 20;
the driver 22 receives the first execution direction instruction and rotates the driving shaft 21, and the lifting member 23 is in threaded fit with the driving shaft 21, so that the lifting member 23 can move linearly in a direction away from the bracket 30, at this time, the threaded section 121 of the supporting rod 12 is not in threaded fit with the second threaded hole 31, and therefore the lifting member 23 pushes the supporting rod 12 to move linearly together through the stopping portion 122, the supporting rod 12 drives the lens module 11 to move, and the lens module 11 is pushed out from the accommodating cavity 203 through the opening 204 until the threaded section 121 moves to be in threaded fit with the second threaded hole 31;
the lifting member 23 continues to move linearly in a direction away from the bracket 30 under the driving of the driving shaft 21, the lifting member 23 continues to push the supporting rod 12 to move through the stopping portion 122, but since the thread section 121 is already in thread fit with the second thread hole 31 at this time, the lifting member 23 drives the supporting rod 12 to rotate relative to the bracket 30 and drives the lens module 11 to rotate together, and at this time, the lens module 11 rotates while moving linearly;
the electronic device 1 receives the second control instruction and sends a second execution instruction to the driving mechanism 20;
the driver 22 receives the second execution instruction and rotates the driving shaft 21 in the reverse direction, the lifting member 23 moves linearly towards the bracket 30, the lifting member 23 pushes the supporting rod 12 to move together through the stopping portion 122, the supporting rod 12 rotates in the reverse direction under the matching of the second threaded hole 31 and the threaded section 121, and drives the lens module 11 to rotate in the reverse direction together, until the threaded section 121 is disengaged from the second threaded hole 31, and the lens module 11 stops rotating;
the lifting member 23 is driven by the driving shaft 21 to continue to move linearly towards the bracket 30, and at this time, the threaded section 121 of the supporting rod 12 is disconnected from the second threaded hole 31, so that the lifting member 23 only pushes the supporting rod 12 to move linearly through the stopping portion 122, and the supporting rod 12 drives the lens module 11 to move together until the lens module 11 retracts from the through hole 204 to the initial position in the accommodating cavity 203.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
