Description

Technical Field

[0001] The utility model relates to the technical field of automobile lenses, in particular to a wide-angle automobile lens system. Background Art

[0002] A rearview mirror is a tool that allows drivers to directly obtain external information from behind, to the sides, and below the vehicle while sitting in the cab. To facilitate operation, prevent traffic accidents, and ensure personal safety, all countries require the installation of rearview mirrors in vehicles. Wide-angle lenses are commonly used in rearview mirrors because they provide a better field of view.

[0003] For example, the Chinese patent "CN206968554U automobile exterior rearview mirror wide-angle lens" includes a reflector; the reflector includes an upper reflection area and a lower reflection area, the upper reflection area is a convex spherical reflector, and the spherical radius is at least 1800mm; the lower reflection area is a convex arc mirror, and the radius of the arc surface is 80mm-180mm; the connecting surface between the upper reflection area and the lower reflection area is smoothly transitioned; the upper edge of the upper reflection area includes a horizontal section and an inclined section with a smooth transition; the two top corners above the upper reflection area are rounded; the two top corners below the lower reflection area are rounded, and the radius of the two rounded corners above the upper reflection area is equal to the two rounded corners below the lower reflection area.

[0004] At present, in the application process of existing wide-angle lenses for automobiles, the wide-angle lenses are generally fixed to the plastic mirror housing by coating glue on the back, and then the plastic mirror housing is clamped together with the adjustment support of the rearview mirror to achieve the installation and fixation of the wide-angle lens. When the wide-angle lens is damaged, the wide-angle lens and the intact plastic mirror housing need to be replaced together, which is costly and causes waste of the intact plastic mirror housing. Utility Model Content

[0005] The present disclosure relates to a wide-angle automobile lens system, which solves the problem that, during the use of existing wide-angle lenses for automobiles, the wide-angle lenses are generally fixedly connected to a plastic mirror housing by coating glue on the back side, and then the plastic mirror housing is clamped together with an adjustment support of a rearview mirror to achieve the installation and fixation of the wide-angle lenses. When the wide-angle lens is damaged, it is necessary to replace the wide-angle lens and the intact plastic mirror housing together, which requires high costs and causes waste of the intact plastic mirror housing.

[0006] In a first aspect of the present disclosure, a wide-angle automotive lens system is provided, specifically comprising: a plastic mirror housing, a wide-angle lens, a limiting strip, and a return spring; the plastic mirror housing is snap-connected to an adjustment support of a rearview mirror, the top of the plastic mirror housing is groove-shaped, and the wide-angle lens is installed in the top of the plastic mirror housing; the bottom of the plastic mirror housing is symmetrically connected to two limiting strips, and the wide-angle lens is connected to the two limiting strips; four return springs are installed at the bottom of the plastic mirror housing.

[0007] Furthermore, four connecting holes are provided inside the plastic mirror shell, and four plugging posts are provided at the bottom of the wide-angle lens, and the plugging posts pass through the connecting holes provided in the plastic mirror shell.

[0008] Furthermore, a positioning ring groove is provided near the bottom end of the plug post, and the positioning ring groove is located outside the bottom of the plastic mirror housing.

[0009] Furthermore, two guide sliding holes are provided on the outside of the limiting strip, and two guide sliding rods are provided on the bottom of the plastic mirror shell. The limiting strip is slidably connected to the guide sliding rods through the guide sliding holes, and the guiding sliding holes and the guide sliding rods are slidably matched to guide the movement of the limiting strip.

[0010] Furthermore, the top side of the limiting strip is in sliding contact with the bottom side of the plastic mirror housing, locking U grooves are provided at both ends of the limiting strip, and the connecting hole is connected to the locking U grooves provided on the limiting strip.

[0011] Furthermore, the bottom end of the plug column is connected to the locking U groove, and the limiting strip is connected to the positioning ring groove.

[0012] Furthermore, the return spring is sleeved on the outside of the guide slide bar provided on the plastic mirror shell, one end of the return spring contacts the plastic mirror shell, and the other end of the return spring contacts the limit strip. When the wide-angle lens is installed in the top of the plastic mirror shell, the plug column passes through the connecting hole, and the positioning ring groove moves to the outside of the bottom of the plastic mirror shell. The limit strip moves inward under the thrust of the return spring, and the distance between the two limit strips is reduced, so that the bottom end of the plug column is connected to the locking U groove, and the limit strip is connected to the positioning ring groove. The wide-angle lens is fixed by the limit strip. When the wide-angle lens is damaged and needs to be disassembled and replaced, the limit strip is moved in the opposite direction, and the distance between the two limit strips increases. The return spring gradually contracts, so that the bottom end of the plug column is separated from the locking U groove, and the limit strip is separated from the positioning ring groove. The wide-angle lens can be separated from the plastic mirror shell, and the damaged wide-angle lens can be replaced.

[0013] The utility model provides a wide-angle automobile lens system, which has the following beneficial effects:

[0014] When the utility model is in use, the guide sliding hole and the guide sliding rod slide together to guide the movement of the limit strip; when the wide-angle lens is installed in the top of the plastic mirror shell, the plug post passes through the connecting hole, the positioning ring groove moves to the outside of the bottom of the plastic mirror shell, and the limit strip moves inward under the thrust of the reset spring, and the distance between the two limit strips is reduced, so that the bottom end of the plug post is connected to the locking U groove, and the limit strip is connected to the positioning ring groove. The wide-angle lens is fixed by the limit strip, thereby ensuring the firmness of the connection between the wide-angle lens and the plastic mirror shell.

[0015] In addition, when the wide-angle lens is damaged and needs to be disassembled and replaced, the limit strips are moved in the opposite direction, the distance between the two limit strips increases, and the reset spring gradually contracts, so that the bottom end of the plug column is separated from the locking U-groove, and the limit strips are separated from the positioning ring groove. The wide-angle lens can be separated from the plastic lens shell, and the damaged wide-angle lens can be replaced, making the replacement of the wide-angle lens easier. The plastic lens shell can be reused, reducing the cost of a single replacement and avoiding waste.
