The functional module according to claim 10, wherein the inner side wall of the guide groove is provided with a first damping plate, the outer side wall of the guide rod is provided with a second damping plate, and the first damping plate and the second damping plate provide damping force mutually.

13. The functional assembly according to any one of claims 1 to 9, wherein the sliding module further comprises a microphone fixed to the sliding member, and the microphone and at least one of the camera modules are isolated from each other.

14. A mobile terminal, characterized in that the mobile terminal comprises the functional assembly of any one of claims 1 to 13, the mobile terminal further comprises a display screen fixedly connected to the base, and the sliding direction of the sliding member is parallel to the display screen.

15. The mobile terminal of claim 14, wherein the display screen has a display area, and the sliding member slides to be overlapped with the display screen, and the display area partially covers or completely covers the camera module.

16. The mobile terminal of claim 15, wherein the display has a non-display area, the non-display area forming a narrow edge.

17. The mobile terminal of claim 14, wherein the base is provided with a receiving cavity, and the display covers the receiving cavity.

18. The control method of the mobile terminal is characterized in that the mobile terminal comprises a base, a camera module, a first driving mechanism and a second driving mechanism, the camera module is telescopically and slidably connected with the base, the first driving mechanism is connected with the base and the camera module, the second driving mechanism is connected with the first driving mechanism and the camera module, and the control method of the mobile terminal comprises the following steps:
