Optical component driving mechanism, imaging device, and electronic apparatus

Abstract

The invention relates to an optical component driving mechanism, an imaging device and an electronic apparatus. The defects that an existing single-carrier driving design is unreasonable and the like are overcome. The optical component driving mechanism comprises: a base which is provided with a single carrier accommodating space; a single carrier which is positioned in the single carrier accommodating space; two elastic sheet accommodating spaces, wherein one elastic sheet accommodating space is located between one end of the X axis of the single carrier and one end of the X axis of the base, and the other elastic sheet accommodating space is located between the other end of the X axis of the single carrier and the other end of the X axis of the base; and two elastic sheets, wherein one elastic sheet is arranged in one elastic sheet accommodating space and is connected with the single carrier and the base respectively, and the other elastic sheet is arranged in the other elastic sheet accommodating space and is connected with the single carrier and the base respectively. The two elastic sheets are distributed along the direction of an incident optical axis of the optical component. The driving mechanism has the advantage of more reasonable design.

Description

Technical field [0001] The present invention belongs to the technical field of electronic device parts, for example, optical prisms driving, and more particularly to an optical member drive mechanism and an imaging device and an electronic device. Background technique [0002] The dosal motor is widely used in a variety of imaging devices or electronic devices. [0003] The existing bosurometric motor is generally used for the structure of the double carrier, which carries the optical prism, and the optical prism has an incident optical axis and the exit optical axis, and the carrier and the base are driven around the case where the anti-shake drive structure is used. The slice of the X-axis and the Y-axis is two different types of shrapnels, which not only has the increase in cost, but also the problem of inconsistency between double-echo slides, which is not conducive to the development trend of mobile phone camera motor; The person is designed with two opposing elastic connect...

AI Technical Summary

Problems solved by technology

[0003]The existing periscope motor generally adopts a double-carrier structure, which carries an optical prism, and the optical prism has an incident optical axis and an outgoing optical axis. In the case of the shaking drive structure, two different shrapnels are connected between the carrier and the base to drive around the X-axis and Y-axis respectively, which not only increases the cost, but also may cause the problem of inconsistent shaking of the double shrapnel. It is also unfavorable for the development trend of miniaturization of mobile phone camera motors; and the inventor has also designed and used two opposite shrapnels to elastically connect the carrier and the base, and each shrapnel is connected to the carrier by two connection points on the upper side and the lower side. When the carrier rotates around the X-axis, it is limited by four connection points, which requires a very large X-axis electromagnetic torque to drive the carrier to rotate around the X-axis, which not only reduces the sensitivity of the carrier around the X-axis, but also reduces the size of the carrier around the X-axis. X-axis rotation angle, unreasonable design, affects the use of camera devices or electronic equipment, and is not conducive to the development trend of miniaturization of mobile phone camera motors
