CAMERA MODULE BASE, CAMERA MODULE AND MOBILE TERMINAL

A camera module base and a camera module. A circuit board can slide under the action of a driving force, thereby driving a photosensitive chip to shift with respect to a lens assembly to realize optical shake prevention. The circuit board is supported by a plurality of balls for better stability. Moreover, since the circuit board and the balls are in point contact, when the circuit board slides, the balls roll quickly under the action of friction. Therefore, the circuit board is subjected to less friction during a sliding process, and thus, the response is fast, the sensitivity is higher, and the energy consumption is lower. In addition, although the balls roll with the circuit board, a sliding plane defined thereby remains constant, and thus, the circuit board slides with better flatness. When the camera module is assembled, firstly, the balls are mounted through an opening of a large end of an accommodation hole, and then a bottom plate is mounted. In this way, the balls can roll normally without falling ou
