Description

Technical Field

[0001] The utility model relates to the technical field of exterior rearview mirrors, and in particular to a device for measuring the adjustment angle of an exterior rearview mirror lens. Background Art

[0002] The adjustment angle of the exterior mirror is closely related to driving safety. The larger the adjustment angle, the wider the driver's field of view. Driving safety can only be guaranteed if the lens has a sufficiently large adjustment angle. Therefore, testing the adjustment angle of the exterior mirror is an important indicator of whether the exterior mirror is functionally qualified. Exterior mirror suppliers and OEMs will test the adjustment angle of the exterior mirror.

[0003] In the prior art, an angle ruler is usually used to measure the adjustment angle of the exterior rearview mirror lens. The adjustment of the exterior rearview mirror lens includes adjustment in both the horizontal and vertical directions, so the adjustment angle of the exterior rearview mirror lens includes the horizontal adjustment angle and the vertical adjustment angle. When using an angle ruler to measure the horizontal adjustment angle, place the angle ruler along the horizontal axis of the exterior rearview mirror lens, adjust the lens to an extreme position, reset the angle ruler to zero, and then adjust the lens to another extreme position. The value displayed by the angle ruler is the horizontal adjustment angle of the lens; when using an angle ruler to measure the vertical adjustment angle, place the angle ruler along the vertical axis of the exterior rearview mirror lens, adjust the lens to an extreme position, reset the angle ruler to zero, and then adjust the lens to another extreme position. The value displayed by the angle ruler is the vertical adjustment angle of the lens.

[0004] Using an angle ruler to measure the adjustment angle of the exterior rearview mirror lens has the following disadvantages: first, the angle ruler itself is heavier than the lens. When the angle ruler is placed on the surface of the exterior rearview mirror lens for measurement, the weight of the angle ruler itself will have a certain impact on the measurement result; second, when using an angle ruler to measure the adjustment angle of the exterior rearview mirror lens, it is usually necessary to place the exterior rearview mirror flat so that the lens is in a horizontal position for measurement. On the entire vehicle, the exterior rearview mirror lens is in a vertical position. The different states of the exterior rearview mirror lens will have a certain impact on the measurement result.
