Problems solved by technology

[0002] In some precision optical products, it is particularly important to realize the smooth operation of the lens group and high-precision automatic optical zoom mechanical equipment, and most of these mechanical equipment in the prior art are driven by gears, racks, belts, and cams. Such methods convert the power source into the linear motion of the corresponding lens group to realize automatic optical zoom, but the errors generated in these intermediate transmission processes affect the transmission accuracy and smooth operation of the system

Abstract

The application discloses a lens module, electronic equipment and vehicle-mounted equipment. The lens module includes a casing, a lens group and a first limiting member. Wherein, the lens group is installed on the housing, the first limiting member includes a magnetic member and an absorbing member, the magnetic member is installed on the housing and the absorbing member is installed on the lens group, or the magnetic member is installed on the lens group and the absorbing member is installed For the housing, the magnetic component can generate a magnetic attraction effect on the absorbing component to limit the lens group's deviation along a plane perpendicular to the preset axis. The effect of the magnetic attraction force of the first stopper can make the lens group not deviate in other directions in the plane perpendicular to the preset axis during the movement along the preset axis, so it can be guaranteed Smooth, high-precision automatic optical zoom of the lens group.

Description

technical field [0001] The present application relates to the field of camera technology, in particular to a lens module, electronic equipment and vehicle-mounted equipment. Background technique [0002] In some precision optical products, it is particularly important to realize the smooth operation of the lens group and high-precision automatic optical zoom mechanical equipment, and most of these mechanical equipment in the prior art are driven by gears, racks, belts, and cams. Such methods convert the power source into the linear motion of the corresponding lens group to realize automatic optical zoom, but the errors generated in these intermediate transmission processes affect the transmission accuracy and smooth operation of the system. Contents of the invention [0003] Embodiments of the present application provide a lens module, electronic equipment, and vehicle-mounted equipment, which can ensure stable and high-precision automatic optical zooming of the lens group...
