Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure detection, and in particular to a vehicle tire pressure detection device. Background Art

[0002] Automobile tires are rubber products mounted on vehicle wheels, supporting the weight of the vehicle, providing contact with the ground, providing traction, cushioning impacts, and ensuring driving stability. As the sole point of contact between the vehicle and the ground, tires significantly impact driving safety, comfort, and fuel economy.

[0003] In the prior art, a Chinese patent with publication number "CN215065008U" discloses a tire pressure detection device for automobile inspection. By providing a storage seat and a base, the pressure gauge can be firmly placed on a platform or the ground for tire pressure detection operation. By providing an adjustment component to drive the pivot to rotate, the viewing angle of the pressure gauge can be adjusted, which is suitable for long-term operation. By providing a buffer component, when the pressure gauge is squeezed, the impact of the buffer component can be reduced, which solves the problem that the existing detection device cannot adjust the angle of the pressure gauge, resulting in the pressure gauge being unable to pay attention to the appropriate viewing angle.

[0004] After a long period of use, automobile tires need to be tested for tire pressure. The main reason is to ensure driving safety, improve driving performance and extend tire life. In the solution described above, a person manually moves the entire detection device to the position of the automobile tire, and uses the pressure gauge and the air pipe to complete the tire pressure detection of the automobile tire. However, in this solution, since the monitoring device needs to be manually moved by a person, manually moving the detection device is not only time-consuming and labor-intensive, but also easily leads to low work efficiency, especially when multiple tires need to be frequently tested, which increases the complexity of manual operation.
