Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior rearview mirrors, in particular to a mounting structure for an electric folding device of an automobile exterior rearview mirror. Background Art

[0002] The exterior rearview mirror of a car is an important safety device for the car and is of great significance to driving safety. When the car enters a smaller area such as an alley or parking space, the frame of the exterior rearview mirror is the widest part of the car body. At this time, in order to prevent scratches and reduce the parking space, and to ensure that the damage to rearview safety is minimized, the frame needs to be folded. Therefore, the exterior rearview mirror of the car is equipped with an electric folding device to facilitate the driver to adjust it in the car. At present, the base and the mounting structure of the electric folding device are installed by a snap-fit ​​method, which has a narrow scope of application and a relatively simple installation method. Summary of the invention

[0003] The embodiment of the present application provides a mounting structure for an electric folding device for an automobile exterior rearview mirror, and connects the mounting structure with a limit plate of the electric folding device via a connecting piece, thereby increasing the mounting methods and expanding the application scope of the electric folding device.

[0005] Compared with the prior art, the advantages of the utility model are:

[0006] The bottom surface of the cavity of the mounting structure abuts against the lower end surface of the limit plate, and the shell and the base are connected by a connecting piece. Compared with the prior art in which the electric folding device and the mounting mechanism are fixedly connected only by snapping together, an installation method in which the electric folding device and the mounting structure are connected by a connecting piece is added, thereby making the electric folding device more applicable.

[0007] As an improvement, the bottom surface of the cavity is provided with a plurality of first through holes along the circumference of the center hole, the limiting plate is provided with second through holes corresponding to the first through holes along the circumference of the center hole, the inner wall of the base is provided with threaded holes corresponding to the first through holes, the connecting piece passes through the first through hole and the second through hole and is threadedly connected to the threaded hole, when the mounting structure is connected to the electric folding device through the connecting piece, the connecting piece passes through the first through hole and the second through hole and is threadedly connected to the threaded hole on the inner wall of the base, the shell, the limiting plate and the base are connected through the connecting piece, if the mounting structure needs to be removed from the electric folding device, only the connecting piece needs to be loosened, which facilitates the installation and disassembly of the mounting structure and the electric folding device.

[0008] As an improvement, the outer wall of the base is evenly distributed with a plurality of open grooves along the circumferential direction, and the inner wall of the cavity is circumferentially provided with limit blocks corresponding to the open grooves, the upper end of the limit block is inserted into the interior of the open groove and abuts against the bottom surface of the open groove, and the two sides of the limit block abut against the side walls of the open groove, and limit blocks corresponding to the open grooves are provided to facilitate the installation of the shell and the positioning of the first through hole, the second through hole and the third through hole, so that the first through hole, the second through hole and the third through hole are on the same axis, and when the upper end of the limit block is inserted into the interior of the open groove and abuts against the bottom surface of the open groove, and the two sides of the limit block abut against the side walls of the open groove, the shell can be prevented from circumferential movement.

[0009] As an improvement, the side walls of the opening groove are inclined, and the width of the bottom surface of the opening groove is smaller than the width of the opening of the opening groove, so that the upper end of the limiting block can be inserted into the interior of the opening groove.

[0010] As an improvement, the outer wall of the limit plate is concavely provided with a plurality of cut surfaces, the limit block is convexly arranged relative to the inner wall of the cavity, and the cut surfaces abut against the lower end of the limit block. Since the cut surfaces are concavely arranged, the limit block is convexly arranged and the cut surfaces abut against the lower end of the limit block, the limit plate can be limited to prevent the limit plate from circumferential rotation, thereby preventing the electric folding device from circumferential rotation.
