Upper spring structure, OIS motor and photographic device

Abstract

The invention discloses an upper spring structure, an OIS motor and a photographic device. The key points of the technical scheme are that the upper spring structure comprises an upper spring and a suspension wire, the upper spring is provided with a fixing part connected with the suspension wire, and the fixing part comprises a bevel edge part and two cantilever parts which are integrally formedwith the bevel edge part. The bevel edge part is fixedly connected to a motor main body of the OIS motor, the connecting ends of the two cantilever parts are provided with welding parts fixed to the suspension wire, and the welding parts extend to the inner side of the included angle of the two cantilever parts. Penetrating holes allowing the suspension wire to penetrate through are formed in thewelding parts, the cantilever parts are provided with first bent structures bent in an arc shape, and the cross section areas of the cantilever parts are sequentially decreased from the bevel edge parts to the welding parts. According to the present invention, the suspension wire is arranged in the penetrating hole in a penetrating manner and is subjected to tin soldering, so that the effect of effectively fixing the suspension wire is achieved; the suspension wire is arranged in the penetrating hole in a penetrating manner, the suspension wire can be prevented from falling off when the OIS motor is impacted or shaken, and the fixing strength is improved.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to an upper spring structure, an OIS motor and a photographic device. Background technique [0002] At present, the OIS motor mainly includes the main body of the voice coil motor and the anti-shake mechanism connected to the main body of the voice coil motor, and the existing OIS motor anti-shake mechanisms mainly include the translation type, the shaft shift type, the memory metal type, and the suspension wire type. [0003] In the existing suspension wire motor, one end of the suspension wire is connected to the base of the OIS motor, and the other end is connected to the main body of the voice coil motor; The coil on the carrier, the upper spring and the lower spring arranged between the frame and the carrier. [0004] The existing application number: 201911341921.3 patent discloses an OIS motor. In this patent, the upper spring in the main body of the voice coil motor is ...

AI Technical Summary

Problems solved by technology

[0005] During the long-term use of the OIS motor, when the OIS motor shakes, it is easy to break at the right-angled side of the fixed part, and at the same time, the existing suspension wire is stuck into the fixed part In the slot at right angles, when the main body of the voice coil motor shakes, the suspension wire and soldered tin are separated from the opening of the slot, resulting in the failure of the OIS motor to work normally
