Description

Lens mount module

Technical Field

The present invention relates to a lens mount module, and more particularly, to a lens mount module with adjustable tilt angle.

Background

With the development of technology, various intelligent image capturing devices are widely used in daily life, wherein a dual-lens or multi-lens image capturing device can be applied to security monitoring, 3D image construction, Virtual Reality (VR) or panoramic images, and is one of the main image capturing devices at present.

In order to perform image stitching, the multi-lens module often requires the precision of image alignment of the lens image capturing system, so that the alignment of the multi-lenses becomes an important issue.

Generally, the assembly method of multiple lens modules is mainly to place the lens modules on the carrying surface of a base (Holder) for direct dispensing and fixing, and in the dispensing and molding process, it is often difficult to adjust the image tilt angle alignment, or to use a camera tilt angle adjustment fixture to clamp the lens modules, rotate the lens modules to the required image tilt angle, and then dispense and fix the lens modules.

However, although the image tilt angle can be adjusted by using the jig, the cost of the jig is high, and a long development time of the jig is required to manufacture the jig and the rotating structure on the jig. In addition, the lens module is fixed by dispensing, and the glue must be removed during maintenance, so that the loss of the lens module is easily caused, and if the weight of the lens module is heavier, the lens module adopting the dispensing fixing mode is less prone to bearing the impact caused by falling or collision, and is easily deformed or damaged.

Disclosure of Invention

In view of the above, the present invention provides a lens mount module, which can adjust the tilt angle of a lens to meet the requirement of image stitching of a wide-angle lens, and has the advantages of reducing manufacturing cost, saving development time, facilitating maintenance and improving impact resistance.

The lens mount module of the embodiment of the invention comprises a bearing mount, a plurality of lens mounts, a plurality of locking components and a plurality of elastic elements. The bearing seat is provided with a plurality of bearing surfaces facing different directions. The plurality of lens bases are respectively arranged on the bearing surfaces. Each of the elastic elements is respectively arranged between one of the lens bases and the corresponding one of the bearing surfaces. The locking components lock the lens bases on the bearing seat and are used for adjusting the relative position or the inclination angle of each lens base relative to the corresponding bearing surface through the deformation and the elastic restoring force of the elastic elements during locking.

Based on the above, the lens mount module of the embodiment of the invention includes a carrying mount, a plurality of lens mounts, a plurality of locking members and a plurality of elastic elements, the lens bases are locked on the bearing seats through the locking component, the elastic elements are arranged between each lens base and the corresponding bearing surface, and through the deformation and the elastic restoring force of the elastic elements, when the lens bases are locked, the relative position or the inclination angle of each lens base relative to the corresponding bearing surface is adjusted, therefore, the inclination angle of the lens can be adjusted during the assembly process to meet the image stitching requirement of the wide-angle lens, and the advantages of reducing the manufacturing cost and saving the development time can be achieved, in addition, because the locking component is used for fixing the lens module, the process of disassembling the lens module can be simplified during maintenance, the damage caused by glue removal can be avoided, and the impact bearing capacity of the multiple lens modules can be improved.
