Description

Technical Field

[0001] The invention relates to the technical field of automobile components, in particular to a front side rearview mirror. Background Art

[0002] The existing side external environment of the vehicle is mainly observed through rearview mirrors and windows. The device allows the driver to observe the rear environment of the vehicle with a wide field of vision, but the front and side environments of the vehicle are mostly blind. At the same time, the existing rearview mirror has a large windward cross-section, which increases energy loss.

[0003] In order to solve the above technical problems, corresponding technical solutions can be found in the public patent documents, such as the "automobile rearview mirror without blind spots" recommended by the authorization announcement number CN2584459Y. This patent solution is to add a small convex mirror to the upper part of the vehicle rearview mirror body by AB glue bonding, and the curvature radius of the convex mirror is designed to be 40-50mm. This patent solution is known to make up for the shortcomings of Chinese patents ZL90205503.8, ZL91203189.1 and ZL95205332.2, but from the description of the content of its specification and the structure of the diagram, it can be seen that the added rearview mirror does not have the function of reflecting the aforementioned blind spots, but only plays the function of expanding the mirror surface of the rearview mirror. Furthermore, authorization announcement number CN201712539U provides a "car rearview mirror". Since this patent solution provides an additional mirror at the lower part of the vehicle rearview mirror body through a mirror base and a hose, the aforementioned CN2584459Y also has the function of not reflecting the blind spot.

[0004] Therefore, new technical solutions are urgently needed to solve the problems existing in the existing technologies. Summary of the invention
