Problems solved by technology

The reed in the voice coil motor has the function of bearing and displacement recovery for the lens carrier, but the structure of the reed is very thin and fragile, so the reed and the lens carrier are mainly fixed by glue, which has poor firmness and weak impact resistance, making it difficult to adapt to the increasingly Frequent mobile phone camera operations

Abstract

The invention discloses a double-reed lens driving device. The double-reed lens driving device includes a square shell, a square lens carrier and a fixing base; the exterior of the square lens carrier is wound with a coil; a gasket is arranged above the square lens carrier; a first reed is arranged between the top of the square lens carrier and the gasket; a second reed is arranged between the bottom of the square lens carrier and the fixing base; the first reed includes a first outer square frame and a first inner circular ring connected with the first outer square frame; the first inner circular ring is provided with a plurality of first gluing holes; and the inner hole of the first inner circular hole is provided with at least eight trapezoidal limiting grooves. According to the double-reed lens driving device of the invention, the square lens carrier is fixed between the first reed and the second reed, and therefore, the double-reed lens driving device has the advantages of high connection reliability, excellent anti-impact performance, little possibility of positioning deviation, high precision, high stability and prolonged service life.

Description

technical field [0001] The invention relates to the field of camera lens driving, in particular to a double reed lens driving device. Background technique [0002] A voice coil motor is a motor used in high-pixel miniature digital cameras with auto-focus function. Miniature digital cameras are not limited to applications such as mobile phones, computers, automobiles, security, digital cameras, tablet computers, and MP3 players, etc. The movement of the lens is usually performed by a motor as a driving device, which is commonly called lens drive in the industry. Devices and motors generally use voice coil motors (English name: Voice Coil Motor, referred to as VCM), and the principle of driving the lens movement by the voice coil motor comes from the speaker. [0003] With the advancement of technology, the structure of miniature digital cameras is becoming smaller and smaller, and the requirements for voice coil motors are getting higher and higher, especially the cameras us...
