Description

Technical Field

[0001] The utility model relates to the field of brake pad detection devices, in particular to a wear detection device for brake pads. Background Art

[0002] Brake pads are wear parts of the automobile braking system. Generally, they need to be replaced when the vehicle mileage reaches a certain value or the brake pads show obvious wear, resulting in a decrease in braking ability. The need for brake pad replacement is mainly determined by visual inspection of the brake pads. Not only the remaining thickness should be checked, but also the wear state of the shoe and whether the degree of wear on both sides is the same. When the brake pad thickness is only about 1 / 3 of the original thickness (about 0.5cm) left by naked eye, the brake pad needs to be replaced.

[0003] When inspecting the brake pads installed on the car, the degree of wear is not easy to observe because the worn end is close to the wheel axle. It is necessary to remove it for inspection during car maintenance. If the replacement requirements are met, a new brake pad will be installed on the car. If the degree of wear is low, it can be reinstalled. However, the car is blocked by the body of the car and the light is dim. When removing the brake pads for naked eye observation, it is necessary to take it to a bright light environment away from the car, which makes inspection more troublesome.

[0004] Therefore, in order to address the problems that the automobile brake pads are inconvenient to be inspected with the naked eye in a dark environment next to the car, it is troublesome to inspect them in a bright environment far away from the car body, and it is inconvenient to quickly install the brake pads back on the car after inspection, a device can be designed to add a light source next to the car body to quickly perform visual inspection of the removed brake pads nearby.
