Motor, lens module and terminal device

The motor comprises a static assembly and a dynamic assembly, the static assembly comprises a blocking piece, the blocking piece comprises a rubber body, and the rubber body has elasticity; the dynamic assembly is movably connected with the static assembly, the blocking piece is used for limiting movement of the dynamic assembly, and the dynamic assembly can impact the blocking piece and/or can slide relative to the surface of the blocking piece; the blocking piece further comprises lubricating grease which is located on the surface of the colloid. Lubricating grease is formed on the surface of the elastic colloid, so that the friction coefficient of the blocking piece is reduced, and chippings are reduced or avoided; the lubricating grease has weak viscosity; the barrier may also be a colloid containing a reinforcing agent to reduce the coefficient of friction of the barrier and enhance the strength of the barrier. In the working process of the motor, when the dynamic assembly collides with the blocking piec
