Description

Technical Field

[0001] The utility model relates to the technical field of tire residual deflection detection, in particular to a handheld tire residual deflection detector. Background Art

[0002] Tires are important parts of cars, and the use of tires is related to the safety of car driving. In the process of driving, in order to ensure that the car can generate enough driving force during driving, it is necessary to set patterns on the tread of the tire to increase the friction coefficient between the tire and the ground and prevent the wheel from slipping. The pattern on the tread of the car tire can not only increase the friction, but also help the tire to dissipate heat. As the car is used for a longer time, the tire will wear out. When the depth of the tire pattern is too shallow, on the one hand, it will reduce the grip of the tire; on the other hand, the water storage capacity will decrease, which is easy to cause "hydroplaning", which brings great safety hazards to driving. Therefore, the depth of the car tire pattern should be detected in a timely and effective manner.

[0003] In the prior art, there is a Chinese invention patent with publication number CN107339966B and the name of a tire tread depth detection device. A step hole is set on the support plate, a detection rod is set in the step hole, and a connecting piece is set at the bottom of the step hole. An elastic element is set in the detection hole so that the upper end of the detection rod is pushed out of the support plate; when the tire rolls over the support plate, the detection rod can be pressed down a certain distance, and the position sensor set on the detection rod can detect the distance that each detection rod is pressed down; the value of the distance that the detection rod extends out of the support rod in the natural state is filtered out, and the depth value of the tire pattern can be obtained. This detection device has a complex structure and needs to move the tire, which is laborious and troublesome, and is not convenient to use. Therefore, there is an urgent need for a handheld residual tread detector for tires, so that the residual tread depth of the tire can be detected anytime and anywhere without moving the tire, which is convenient, fast and efficient.
