Problems solved by technology

[0003] Due to the small structure of the existing voice coil motor and the tight fit between multiple parts, the hot riveting space of the upper spring 3 is small, and it is not easy to operate during the hot riveting operation
And when the spring is hot riveted, the spring wrist (between the spring cantilever and the spring connection end) will undergo relative rotation and deformation, which will affect the performance of the voice coil motor

Embodiment 1

[0032] Embodiment 1: as Figures 1 to 7 As shown, a motor assembly and fixing structure proposed by the present invention includes a base 1, a carrier 2, an upper spring 3, a lower spring 4, a magnet 5, and a coil 6. In this embodiment, the carrier 2 is integrally formed with a lens 7, and through The lens 7 and the carrier 2 are integrally formed to reduce the number of components. The lower spring 4 is installed between the lower end surface of the carrier 2 and the base 1. The base 1 is integrally formed with four evenly distributed positioning columns 8. The magnet 5 is set to four and is located at the corner of the base 1 and attached to the positioning columns 8. The side wall, and the upper spring 3 is arranged between the upper end surface of the positioning post 8 and the upper end surface of the carrier 2 . In addition, four assembling grooves 9 are opened on the lower end surface of the base 1 , and the four assembling grooves 9 respectively extend to the inner ca...

Embodiment 2

[0041] Embodiment 2: a voice coil motor, such as Figure 8 As shown, the motor assembly and fixing structure of Embodiment 1 also includes a housing 36, the end of the housing 36 is in contact with the base 1, and the cover plate 15 is in contact with the bottom surface of the housing 36, and the side wall of the cover plate 15 is attached to the inner side of the housing 36. The wall abuts against the cover plate 15 through the bottom surface of the shell 36, which can ensure that the cover plate 15 and the positioning column 8 clamp the outer connection portion 11, and effectively restrict the relative movement of the cover plate 15 and the outer connection portion 11.

Abstract

The invention discloses a motor assembling and fixing structure, a voice coil motor, a photographic device and an electronic product. Key points of the technical scheme are as follows: the motor assembling and fixing structure comprises a base, a carrier, an upper spring, a lower spring, a magnet and a coil, four positioning columns are integrally formed on the base, the upper spring comprises twosymmetrically-arranged upper spring parts, each upper spring part comprises an inner connecting part, an outer connecting part and two upper cantilevers, and the outer connecting parts and the uppercantilevers correspond to the positioning columns; hot riveting columns are integrally formed on the positioning columns, hot riveting holes corresponding to the hot riveting columns are formed in theouter connecting part, the four positioning columns are connected with a cover plate used for covering the outer connecting part, and the cover plate and the positioning columns clamp and fix the outer connecting part. The outer connecting part is clamped and fixed through the cover plate and the positioning column, the upper spring can be effectively fixed, the step of fixing the upper spring tothe positioning column in a hot riveting mode is omitted, accurate positioning is achieved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a motor assembly and fixing structure, a voice coil motor, a photographic device and electronic products. Background technique [0002] The existing voice coil motor structure generally includes a base 1, a carrier 2, a bracket, an upper spring 3, a lower spring 4, and a housing 36. The lens 7 is installed on the carrier 2, and the upper spring 3 is hot riveted on the bracket, and the lower spring 4 is fixed on the Base 1. The existing support and the base 1 are separately arranged or the support and the base 1 are integrated into a whole. The support is provided with a heat riveting post 13, and the upper spring 3 is provided with a heat riveting hole 14 which is sleeved with the heat riveting post 13. When the spring 3 is installed with the support, the hot riveting post 13 is pierced with the hot riveting hole 14, and then the hot riveting post 13 is hot riveted and defo...
