Adjusting device for car rearview mirror

Abstract

The invention discloses an adjusting device used for an automobile rearview mirror. The adjusting device comprises an upper cover (1), a base (6), an electric driving unit, a pin shaft (10), and a large gear (4), a chassis (7) and a spring (11) which sleeve the pin shaft (10) in sequence, wherein the electric driving unit is arranged in a cavity between the upper cover (1) and the base (6); a manual adjusting mechanism is arranged between the chassis (7) and the pin shaft (10), and can slide along the pin shaft (10) in a manual adjusting process to overcome the action of the spring (11) so that the chassis (7) can rotate relative to the pin shaft (10) when the base (6) is manually driven; a limiting mechanism for limiting the driving position of the rearview mirror is further arranged between the large gear (4) and the upper cover (1). The adjusting device has a simple structure and has no force applied to the electric driving unit in the manual adjusting process; the product has a longer service life and better reliability.

Description

technical field [0001] The invention belongs to the field of automobile rearview mirrors, in particular to an adjusting device for automobile rearview mirrors. Background technique [0002] The car rearview mirror is an auto accessory for the driver to observe the running status of the rear vehicles and pedestrians while driving the car. It is a necessary guarantee for safe driving. By adjusting the installation angle of the rearview mirror, the driver can observe Wide field of vision for safe driving. Therefore, the importance of rearview mirrors is well known. And because the rearview mirror is installed on both sides of the car, the foldable rearview mirror installed on the outside of the car often uses an electric drive adjustment device to avoid rearview when the car is driving in a narrow space or in a complicated place with many pedestrians. The mirror collides with other vehicles and pedestrians, causing vehicle damage or unnecessary disputes. But the problem is t...

Problems solved by technology

But the problem is that the electric drive adjustment alone cannot meet people's needs, and the function of manual adjustment needs to be realized, and the adjustment device of the prior art has the following disadvantages, 1. The overall structure is not compact enough

2. During the manual adjustment process, the driver needs to bear a relatively large force, so the strength of the driving device is high and the cost is high

The setting of the shape of each group of cams requires precise design and calculation, and the production cost is relatively high.

And in the process of adjustment, the driver still needs to overcome a certain force. Although it is mentioned in the manual that the force acting on the driver is a relatively small force, the problem is that the requirements for the cooperation between the sets of cams will be very large. At the same time, the pressure of the spring is also difficult to control. If it is too tight, the previous requirements cannot be guaranteed, and it will have a certain impact on the life of the product.
