Description

Technical Field

[0001] The utility model relates to the field of cameras, and more specifically, to a panoramic lens module. Background Art

[0002] A panoramic camera includes multiple fisheye lenses in different directions. The pictures taken by each fisheye lens at the same time are stitched together by a processor to obtain a panoramic image. The fisheye lens is contained in a lens module. Usually, a lens module consists of a fisheye lens and a lens fixing structure. Multiple lens modules in existing panoramic cameras are usually arranged in sequence and fixed on the outer edge of a horizontal base to form a panoramic lens module.

[0003] The existing panoramic lens module is composed of a plurality of lens modules installed in combination. The installation structure of the plurality of lens modules occupies a large space volume. In order to solve the problem of large space volume, a Chinese utility model patent discloses a lens module for a panoramic camera (application number: CN202322063875.3), wherein a module mounting plate and a module fixing plate are rotatably connected to each other, a first rubber plate is arranged on the inner wall of the module mounting plate, a second rubber plate is arranged on the inner wall of the module fixing plate, the lens body is placed in the middle position between the module mounting plate and the module fixing plate, a first mounting plate is installed on one side of the outer wall of the module mounting plate, a second mounting plate is installed on one side of the outer wall of the module fixing plate, and a mounting bolt penetrates the first The mounting plate and the second mounting plate are then fixed using mounting nuts. At this time, the module mounting plate and the module fixing plate clamp and fix the lens body. When clamping, the lens body is protected from being damaged by the elasticity of the first rubber plate and the second rubber plate. The clamping force of the module mounting plate and the module fixing plate is adjusted by loosening the bolts and the mounting nuts or tightening the loose bolts and the mounting nuts. However, if the clamping is too loose, the elasticity of the first rubber plate and the second rubber plate allows the lens body to vibrate between the module mounting plate and the module fixing plate, resulting in instability of the lens body during shooting, and it is even easy to fall out between the module mounting plate and the module fixing plate. If the clamping is too tight, the first rubber plate and the second rubber plate do not have enough elastic deformation space, which will still damage the lens body. Utility Model Content
