Driving device, camera module, electronic equipment and driving device assembling method

Abstract

The invention provides a driving device, a camera module, electronic equipment and a driving device assembling method. The driving device comprises a base, a lower spring, a lens assembly, an upper spring, a coil and a magnet. The base comprises a terminal; the lower spring is elastically arranged between the base and the lens assembly; the lens assembly can be movably arranged on the base relative to the base; the upper spring is arranged on the lens assembly; one end of the terminal is exposed out of the bottom of the base, and the other end of the terminal extends towards the upper spring to be electrically connected with the upper spring; the upper spring is further electrically connected with the coil; the coil is arranged on the lens assembly; and the magnet and the coil are correspondingly arranged. According to the driving device, the camera module, the electronic equipment and the driving device assembling method, the electric connection is realized through the upper spring, the connection process of the terminal and the upper spring can be operated at the upper part of the lens assembly, the operation space is large, the operation is convenient, the lower spring and the lens assembly can be sequentially arranged above the base, all parts do not need to be overturned, the operation is more convenient, and the assembly process is more simplified.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a driving device, a camera module, electronic equipment and a driving device assembly method. Background technique [0002] With the advancement of science and technology, the application of camera modules is becoming more and more extensive. At present, in addition to cameras, electronic devices such as mobile phones and computers are equipped with camera modules to facilitate people to take pictures anytime and anywhere, bringing convenience to people's lives. with fun. The camera module includes a fixed-focus camera module and a zoom camera module. In the zoom camera module, the lens can be driven by a driving device to move to achieve focusing. [0003] The driving device generally includes a base, a lower spring, a carrier, an upper spring, a magnet, a coil and a casing, the lower spring is arranged on the base, the carrier is arranged on the base, and is located between t...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned driving device, since the lower spring is electrically connected to the circuit board, and the lower spring is assembled with the carrier and the coil and then electrically connected to the base, the operation space is small and the operation is inconvenient when connecting.
