Focusing motor and camera module

Abstract

The invention discloses a focusing motor and a camera module, and belongs to the technical field of camera shooting. The focusing motor of the present application comprises: a base; the bearing seat is arranged in the base; the SMA actuating mechanism is arranged on one side of the bearing seat and connected with the bearing seat and the base, and the SMA actuating mechanism is used for driving the bearing seat to move in the height direction of the base; the suspension assembly is used for enabling the bearing seat to suspend in the base; the suspension assembly comprises a plurality of cantilevers and connecting parts, the connecting parts are arranged on the bearing seat, connecting lines between the connecting parts form a triangle, the cantilevers are connected to the same side of the base, and each cantilever is connected with the corresponding connecting part. According to the focusing motor, the size is small, the suspension assembly has good elasticity, impact force of different angles can be borne, and reliability is good.

Description

technical field [0001] The present application relates to the field of camera technology, in particular to a focus motor and a camera module. Background technique [0002] With the development of micro-lens imaging technology, the types and quantities of lens modules, such as telephoto lens modules, wide-angle lens modules and main lens modules, are gradually increasing in the high-end smart electronic devices of major manufacturers, such as flagship mobile phones. In the case of limited volume of electronic equipment, a large number of lens modules will inevitably occupy the volume and quality of intelligent electronic equipment, affect the settings of other functional modules inside the electronic equipment, and also affect the feel. [0003] In order to effectively reduce the size of the lens module and at the same time reduce the quality of the lens module, in the Chinese patent application publication number CN112965199A, there is a lens module, in which the focus motor...

Problems solved by technology

[0004] Although the above-mentioned lens module is small in size, since the elastic piece is connected to the side of the lens bearing seat connected to the actuating mechanism and the side connected to the actuating mechanism on the base, its unique design makes the elastic piece The rigidity in other directions of the moving direction is relatively large. When the lens module is subjected to a large impact force in a certain direction, the shrapnel is easily broken, which will cause the lens carrier to deflect when moving and cause the focus motor to fail.
