Description

Tread depth detection warning device

This creation relates to a tread depth detection warning device, and more particularly to a detection warning device capable of monitoring the tread depth in real time.

The wheel is a circular, scrollable object that rotates about an axis. The tire and the wheel are modified to be an inflated rubber wheel mounted on the axle for moving the body and dampening the ground caused by the gas inside the tire. Generally, the surface of the tire for daily use has a groove for draining sand, that is, a tread, to increase the grip and drainage of the tire for safety purposes. However, the depth of the tread touches the ground as the tire travels, and the wear is getting smaller and smaller. When the tread depth is worn to a low grip, the friction between the tire and the road surface is too low, and the vehicle is easily out of control or slip. Therefore, Taiwan's legislation in Article 33 of the Traffic Management Regulations, the determination of the depth of the tread to be 1.6mm, will be punished if the depth standard is not reached. Therefore, the tread depth must be checked frequently and new tires should be replaced before the tread depth is below the standard depth to avoid the touch and ensure safe driving.

In the prior art, there are various methods for detecting the tread depth. Typically, the tire will have about 5-6 wear indication points in the tread of the tire, and the height of the wear indicator point will be 1.6 mm outward from the bottom of the tread groove. The user detects by visually inspecting the wear indication point of the tire, as long as the tire has worn to any wear indicating point, that is, the tire tread depth is insufficient. At present, some people use measuring instruments to measure the depth of the tread, and use a measuring instrument or an electronic instrument to detect the depth of the tread, so as to accurately know the depth of the tread to ensure driving safety. All of the above detection methods require periodic testing by the user. however, Most people do not check the depth of the tread before driving, and often check the tread depth by the maintenance factory during regular maintenance inspection. However, if the depth of the tread is not always noticed, and the tire is still used in the depth of the tread, such driving conditions are dangerous.

In view of the above, the tread depth detection method in the prior art has the disadvantage that it cannot be detected immediately and is dangerous, and it is necessary to improve.
