Specifically, the shell may include a middle frame, and the through hole may be formed in the middle frame, and of course, the specific forming position of the through hole is not limited in the embodiment of the present invention.
The driven device 100 operates by changing its position. The drive mechanism 200 is typically disposed within the housing. The driving mechanism 200 is connected to the driven device 100, and the driving mechanism 200 drives the driven device 100 to extend out of the housing or retract into the housing through the through hole. In a specific working process, when the driven device 100 needs to work, the driving mechanism 200 drives the driven device 100 to extend out of the shell through the through hole so as to work; when the work is completed, the driving mechanism 200 drives the driven device 100 to retract into the housing through the perforation, thereby achieving concealment within the housing.
In the embodiment of the present invention, the driven device 100 may include at least one of a camera, a flash, and a receiver, and of course, the driven device 100 may also include other driven devices that need to extend out of the housing to operate, and the embodiment of the present invention does not limit the specific structure of the driven device 100.
One of the driven device 100 and the housing is provided with a magnetic member 300, and the other is provided with an electromagnetic device 400. As shown in fig. 1, for example, the driven device 100 is provided with a magnetic member 300, and typically, the magnetic member 300 is a permanent magnet, such as a permanent magnet. An electromagnetic device 400 is arranged in the housing, and specifically, the electromagnetic device 400 may be an electromagnetic coil. The electromagnetic device 400 has magnetism in the energized state, but of course, the direction of the current applied is different, and the direction of the magnetism of the electromagnetic device 400 is also different. In the embodiment of the present invention, the driven device 100 has a center line extending in the moving direction thereof. The electromagnetic device 400 and the magnetic member 300 are both located at one side of the center line, and the electromagnetic device 400 and the magnetic member 300 are matched with each other, so that mutual attraction or mutual repulsion is realized.

In the process that the driven device 100 moves from the outside of the housing to the inner cavity, the electromagnetic device 400 and the magnetic member 300 are magnetically attracted, in this case, the electromagnetic device 400 exerts magnetic attraction on the magnetic member 300, the magnetic attraction and the pulling force exerted by the driving mechanism 200 are respectively located on two sides of the central line, so that the situation that the driven device 100 is under the pulling force of the driving mechanism 200 on one side in the retraction process can be avoided, the magnetic attraction is on the other side of the driven device 100, and the pulling force exerted by the driving mechanism 200 on the driven device 100 can be balanced.
In a specific embodiment, the driving mechanism 200 is connected to one end of the bottom of the driven device 100, and the magnetic member 300 is disposed at the other end of the bottom of the driven device 100. For another example, the driving mechanism 200 is connected to a first side edge of the driven device 100, and the magnetic member 300 is disposed on a second side edge of the driven device 100, the first side edge and the second side edge being opposite to each other.
In the process that the driven device 100 moves from the inner cavity to the outside of the housing, the magnetic repulsion between the electromagnetic device 400 and the magnetic member 300 is achieved, in this case, the driving mechanism 200 applies a thrust force to the driven device 100, and the magnetic repulsion applied by the electromagnetic device 400 to the magnetic member 300 is consistent with the thrust direction, so that the driven device 100 can be prevented from being pushed by the driving mechanism 200 on one side in the extending process, and the purpose of balancing the thrust force is achieved.

Since the magnetic members 300 and the electromagnetic members 400 are distributed on one side of a center line extending along the moving direction of the driven device 100, and the driving mechanism 200 is located on the other side of the center line, during the retraction of the driven device 100, the magnetic attraction between the electromagnetic members 400 and the magnetic members 300 can balance the pulling force applied by the driving mechanism 200 to the driven device 100, thereby avoiding the deflection of the driven device 100 during the retraction; during the process of extending the driven device 100, the magnetic repulsion between the electromagnetic device 400 and the magnetic device 300 can balance the thrust applied to the driven device 100 by the driving mechanism 200, so that the driven device 100 can be prevented from deflecting during the extending process. Therefore, the electronic device disclosed by the embodiment of the invention can relieve the deflection phenomenon of the driven device 100 in the moving process.
The electronic equipment disclosed by the embodiment of the invention comprises a mainboard 500, wherein the mainboard 500 is provided with an avoiding notch 510, in the process that the driven device 100 moves to an inner cavity from the outside of the shell, the driving mechanism 200 drives the driven device 100 to move to the avoiding notch 510, and the avoiding notch 510 can accommodate the driven device 100, so that the driven device 100 is prevented from being stacked with the mainboard 500, and the electronic equipment is favorably designed towards a thinner direction.
Similarly, the driving mechanism 200 can be disposed in the avoiding notch 510, and this assembly structure can avoid the overlapping of the driving mechanism 200 and the main board 500, which is also beneficial for the electronic device to be designed toward a thinner direction. The driving mechanism 200 is electrically connected to the motherboard 500, and the motherboard 500 supplies power. In the embodiment of the present invention, the driving mechanism 200 is capable of driving the driven device 100 to move, and the type of the driving mechanism 200 may be various, for example, the driving mechanism 200 may be a hydraulic telescopic driving element, a pneumatic telescopic driving element, a lead screw driving mechanism, and the like, and the embodiment of the present invention is not limited to the specific type of the driving mechanism 200.

In a preferred embodiment, the electromagnetic device 400 is disposed on the motherboard 500, and the electromagnetic device 400 is electrically connected to the motherboard 500 and is powered by the motherboard 500. In this case, the main board 500 not only provides a mounting position for the electromagnetic device 400, but also can supply power to the electromagnetic device 400.
In order to make the action effect between the electromagnetic device 400 and the magnetic member 300 better, in a preferable scheme, the electromagnetic device 400 and the magnetic member 300 are arranged opposite to each other in the moving direction of the driven device 100.

The controller is connected to the first hall device 600 and the second hall device 700, and the controller is connected to the driving mechanism 200. The controller controls the driving mechanism 200 to be turned off according to the variation of the magnetic flux sensed by the first hall device 600 or the second hall device 700.
Specifically, in the process that the driving mechanism 200 drives the driven device 100 to extend, the magnetic member 300 can gradually approach the second hall device 700 and gradually move away from the first hall device 600, in this case, the second hall device 700 senses the magnetic flux of the magnetic member 300, when the magnetic flux of the magnetic member 300 sensed by the second hall device 700 reaches the first preset value, it indicates that the driven device 100 has extended in place, and the controller controls the driving mechanism 200 to close according to the first preset value sensed by the second hall device 700, so that the extending movement of the driven device 100 is stopped.
In the process that the driving mechanism 200 drives the driven device 100 to retract, the magnetic member 300 can gradually approach the first hall device 600 and gradually move away from the first hall device 600, in this case, the first hall device 600 senses the magnetic flux of the magnetic member 300, when the magnetic flux of the magnetic member 300 sensed by the first hall device 600 reaches a second preset value, it indicates that the driven device 100 has retracted to the right position, and the controller can control the driving mechanism 200 to close according to the second preset value sensed by the first hall device 600, so that the retraction movement of the driven device 100 is stopped.
