Description

Technical Field

[0001] The utility model relates to the field of automobile rearview mirrors, in particular to an elastic compensation structure device of an automobile rearview mirror driver. Background Art

[0002] A rearview mirror is an automotive accessory that allows the driver to observe the status of vehicles and pedestrians behind them while driving. It is essential for safe driving. By adjusting the mirror's angle with the assistance of a mirror actuator, the driver can observe specific directions, facilitating safe driving. However, during adjustment, the upper end of the semi-annular rack is hinged to a floating plate. As the two semi-annular racks move forward and backward and left and right, only the guide grooves in the base provide guidance and position control. This creates a need for improved operational smoothness during rearview mirror adjustment, which can easily cause the mirror surface to vibrate. Summary of the Invention

[0003] The embodiment of the present application provides an elastic compensation structure device for the mirror driver of a car rearview mirror, in which the lower end of the elastic compensation structure is abutted against the upper end of the semi-annular rack, and the upper end of the first limit block is abutted against the lower end of the semi-annular rack. Therefore, when the semi-annular rack moves, both the upper and lower ends of the semi-annular rack are limited, thereby improving the stability of the movement of the semi-annular rack and thus improving the stability of the driver.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elastic compensation structure device of a mirror driver for a car rearview mirror, the mirror driver includes a base, two semi-annular racks, a motor, an upper cover, and a floating plate. The motor is arranged inside the base and drives the semi-annular racks to move. The two semi-annular racks are arranged crosswise with each other. The base is provided with guide grooves corresponding to the semi-annular racks. The outer side of the lower end of the semi-annular rack is embedded in the inner part of the guide groove and cooperates with the guide groove. The upper end of the semi-annular rack passes through the upper cover and is hinged to the floating plate to drive the car rearview mirror to rotate. Elastic compensation structures are provided on both sides of the intersection of the semi-annular racks. The lower end of the elastic compensation structure is abutted against the upper end of the semi-annular rack. A plurality of first limit blocks are protruded on the inner side of the base. The upper end of the first limit block is abutted against the lower end of the semi-annular rack, and the upper end of the elastic compensation structure is abutted against the lower end of the upper cover.

[0005] Compared with the prior art, the advantages of the present invention are:

[0006] Through the guide channel formed by the elastic compensation structure and the first limit block, the upper end of the elastic compensation structure abuts against the lower end of the upper cover to limit the limiting mechanism. When the motor drives the semi-annular rack to move, the lower end of the elastic compensation structure abuts against the upper end of the semi-annular rack, and the upper end of the first limit block abuts against the lower end of the semi-annular rack. Therefore, when the semi-annular rack moves, both the upper and lower ends of the semi-annular rack are limited, thereby improving the stability of the movement of the semi-annular rack and thus improving the stability of the drive.

[0007] As an improvement, the elastic compensation structure includes a first spring sheet and a second spring sheet, the second spring sheet is arranged at two ends of one side of the first spring sheet and connected to the first spring sheet, a semi-annular rack is provided with a first arc guide block on both sides of the intersection, and the other semi-annular rack is provided with a second arc guide block at the front and rear ends of the intersection, the lower end of the first spring sheet is against the upper end of the first arc guide block, the lower end of the second spring sheet is against the upper end of the second arc guide block, the upper end of the first limiting block is against the lower ends of the first arc guide block and the second arc guide block respectively, the lower end of the first spring sheet is against the upper end of the first arc guide block, the upper end of the first limiting block is against the lower end of the first arc guide block, when the first arc guide block moves, it plays a guiding and limiting role for the first arc guide block, the lower end of the second spring sheet is against the upper end of the second arc guide block, the upper end of the first limiting block is against the lower end of the second arc guide block, the second arc guide block is guided and limited.

[0008] As an improvement, the front and rear ends of the first spring piece protrude downwardly to provide a first arc-shaped protrusion, and the lower end of the first arc-shaped protrusion abuts against the upper ends of the front and rear ends of the first arc-shaped guide block. One side of the second spring piece protrudes downwardly to provide a second arc-shaped protrusion, and the lower end of the second arc-shaped protrusion abuts against the upper end of one side of the second arc-shaped guide block. By abutting the lower end of the first arc-shaped protrusion against the upper ends of the front and rear ends of the first arc-shaped guide block and the lower end of the second arc-shaped protrusion against the upper end of one side of the second arc-shaped guide block, the two ends of the first arc-shaped guide block and the second arc-shaped guide block are limited without affecting the moving distance of the semi-annular rack, thereby improving the stability of the movement of the semi-annular rack.

[0009] As an improvement, a number of second limit blocks are provided at the lower end of the upper cover, and the second limit blocks are provided on one side of the second spring piece. The lower end of the second limit block is abutted against the upper end of the second arc-shaped guide block. By abutting the lower end of the second limit block against the upper end of the second arc-shaped guide block, the limitation of the upper end of the second arc-shaped guide block is further strengthened, and the stability of the movement of the semi-annular rack is further improved.

[0010] As an improvement, a third limit block is protruded from one side of the second limit block, and the lower end of the third limit block is abutted against the upper end of the first spring piece. The position of the first spring piece is limited by the abutment between the lower end of the third limit block and the upper end of the first spring piece to prevent the first spring piece from moving when the first arc-shaped guide block moves. Since the first spring piece is elastic, the third limit block limits the first arc-shaped guide block through the first spring piece.

[0011] As an improvement, a fourth limit block is provided at one end of the second limit block, the front end of the first spring piece is abutted against the rear end of the fourth limit block, the rear end of the first spring piece is abutted against the front end of the fourth limit block, one side of the second spring piece is abutted against one side of the fourth limit block, and a fifth limit block is protruding from one side of the fourth limit block, and the lower end of the fifth limit block is respectively abutted against the upper ends of the first spring piece and the second spring piece. The front and rear ends of the first spring piece and one side of the second spring piece are limited by the fourth limit block, and the lower ends of the five limit blocks are respectively limited by the upper ends of the first spring piece and the second spring piece to prevent the first arc guide block and the second arc guide block from driving the first spring piece and the second spring piece to move respectively when they move, so that the lower end of the first spring piece is always abutted against the upper end of the first arc guide block, and the lower end of the second spring piece is always abutted against the upper end of the second arc guide block.
