Abstract

The invention discloses a magnet fixing support which comprises a magnet yoke ring and a fixing support arranged on the magnet yoke ring. The fixing support is buckled on the magnet yoke ring through a connecting blade; and glue dispensing grooves are formed in the two sides of the connecting blade. A magnet and a coil are fixed together through the lower magnet yoke ring and the upper fixing support, it is guaranteed that a driving structure cannot swing at will, and the stability of the whole lens driving device is improved. According to the magnet fixing support of the invention, the glue dispensing grooves at unfilled corner structures at the outer sides of the fixing support ensure smooth glue dispensing, glue does not overflow, material waste is avoided, and the cleanliness of a motor can be kept.

Description

technical field [0001] The invention relates to the field of motors, in particular to a magnet fixing bracket, a lens driving device, a photographing device and electronic equipment. Background technique [0002] In the prior art, after the fixing bracket and the yoke ring of the motor are positioned through the mosaic structure, they are connected and fixed by glue. The disadvantage of this connection method is that it is easy to cause glue leakage during the dispensing operation, resulting in waste of materials, affecting the cleanliness of the entire motor environment, and resulting in unstable connection of the mosaic structure. Contents of the invention [0003] The object of the present invention is to address the deficiencies in the prior art and provide a magnet fixing bracket, a lens driving device, a photographing device and electronic equipment to solve the problems in the prior art. [0004] The technical problem solved by the present invention can adopt follo...
