Problems solved by technology

[0003] The purpose of the present invention is to provide a device and automobile for adjusting tire pressure, which solves the problem that the pressure of automobile tires in the prior art mainly depends on the driver to judge whether it needs to be inflated, the error is large, and the pressure is often low, which affects the life of the tire. Or the pressure is high, resulting in a tire blowout, etc., which brings inconvenience to the driver.

[0062] Such as figure 2 As shown, the first control module 4 includes:

[0063] The first pressure relay YJ1 installed inside the car tire;

[0064] When the pressure value of the automobile tire is less than the first preset value, the first pressure relay YJ1 is closed, the first coil DV1 is charged, so that the reversing valve is in the first state, and the inflation device inflates the automobile tire ; When the pressure value of the automobile tire is greater than the second preset value, the first pressure relay YJ1 is disconnected, the first coil DV1 is de-energized, and under the action of the first return spring, the reversing valve returns to When it is in the second state, the inflation device stops inflating the automobile tires; wherein, the first preset value is less than or equal to the second preset value.

[0065] Specifically, a first pressure relay YJ1 is installed inside the tire of the car. When the tire pressure of the car is lower than the set pressur...

Abstract

The invention provides a tire pressure regulating device and a vehicle. The device comprises an inflation device, a reversing valve used for connecting the inflation device with a vehicle tire, as well as a first control module and a second control module connected with the reversing valve. The first control module controls the reversing valve to be at the first state in the first preset timing, the inflation device is communicated with the vehicle tire through the reversing valve, the vehicle tire is inflated by the inflation device, the first control module controls the reversing valve to be at the second state in the second preset timing, and the inflation device stops inflating the vehicle tire; the second control module controls the reversing valve to be at the third state in the third preset timing, the vehicle tire is communicated with the air through the reversing valve, the vehicle tire deflates to the air, the second control module controls the reversing valve to be at the second state in the fourth preset timing, and the vehicle tire stops deflating. By applying the device provided by the embodiment of the invention, the pressure of the vehicle tire can be changed along with the change of the vehicle speed and the change of the vehicle load, so that the purposes of saving fuel, and improving the security and comfort are realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a device for adjusting tire pressure and an automobile. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles is increasing, and people's requirements for the performance of automobiles are also getting higher and higher. For example, for car tires, different road conditions, different speeds of cars, different loads of cars, etc. have different requirements for the pressure of tires, but generally speaking, the pressure of car tires will be set based on the above reasons. As long as the car tires are kept within the above pressure range, the normal running of the car can be guaranteed. And the pressure of its automobile tire mainly depends on the driver to judge whether it needs to be inflated, and the error is relatively large. Often there is a lower pressure, which affects the life of the tire or the pressure is hig...
