Referring to fig. 12, fig. 12 is a partial structural diagram of a state of a mobile terminal according to an embodiment of the present application. In this state, the electromagnetic coil 1621 is energized in the forward direction, so that a repulsive force is generated between the electromagnetic telescoping motor 162 and the push rod 163, and the push rod 163 is pushed out of the electromagnetic telescoping motor 162, thereby pushing the actuator 1631 fixedly connected to the push rod 163 to move upward along the guide shaft 1613.

Referring to fig. 13, fig. 13 is a partial structural diagram of another state of a mobile terminal according to an embodiment of the present application. In this state, the electromagnetic coil 1621 is reversely energized, so that an attractive force is generated between the electromagnetic expansion motor 162 and the push rod 163, and the push rod 163 is pulled into the electromagnetic expansion motor 162, thereby pulling the driving block 1631 fixedly connected to the push rod 163 to move down along the guide shaft 1613. Because the first magnet 1635 of the driving component 16 and the second magnet 1516 of the camera module 15 are in close proximity and have different magnetism and attract each other, so as to generate a tight electromagnetic connection between the camera module 15 and the driving component 16, the driving block 1631 moves down along the guiding shaft 1613 to drive the camera module 15 to move, and further to pull the camera module 15 into the receiving cavity 1130. Specifically, when the transmission block 1631 moves down to a predetermined position along the guide shaft 1613, the transmission block 1631 abuts against the second blocking plate 1612, and the second blocking plate 1612 is used for limiting the movement of the transmission block 1631; the camera module 15 is also just in time taken in completely and takes in the chamber 1130 at this moment, and the chamber 1511 of the shell 151 of the camera module 15 abuts against the limit baffle 1131, so that the camera module 15 is prevented from further retracting into the shell 11 due to inertia, and the limit baffle 1131 is used for limiting the movement of the camera module 15 at this moment.
