Embodiment Construction
[0020] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0021] see figure 1 , a rapid deflation device for automobile tires, characterized in that it includes a microprocessor 1 connected to an LCD display 2, the microprocessor 1 is wirelessly connected with a tire pressure detection device 3 arranged on the wheel hub, and the microprocessor 1 The control end is wirelessly connected with the tire control device 4 , and the tire control device is connected with the deflation valves 5 , 6 , 7 , and 8 .
[0022] The tire pressure detection device 3 transmits the tire pressure value signal to the microprocessor 1 after A / D conversion.
[0023] The deflation valves 5, 6, 7, 8 are opened by the tip of the tire control device 4 extending toward the valve of the deflation valve to deflate.
[0024] The LCD display is installed in the driver's cab so that the driver can check the tire pressure value at any ...

The invention discloses a device for quickly deflating a tire of an automobile. The device comprises a microprocessor which is connected with an LCD (liquid crystal display), wherein the microprocessor is positioned in a dashboard and is wirelessly connected with a tire pressure detection device which is arranged on a hub; the control end of the microprocessor is wirelessly connected with a tire control device; the tire control device is connected with a plurality of deflation valves which are uniformly distributed on the hub. According to a method for deflating the tire through the device, when the microprocessor determines that the tire pressure needs to be quickly reduced according to a received signal, a tire pressure reduction command is wirelessly sent to the tire control device, and the tire control device immediately turns on the deflation valves which are uniformly distributed on the hub, so that the tire pressure of the tire is quickly reduced to a certain value; for instance, during emergency braking, the automobile can stop within the shortest time, so that the safety performance of the automobile can be greatly improved.
Description
technical field [0001] The invention belongs to the technical field of tires, in particular to a rapid deflation device and method for automobile tires. Background technique [0002] With the development of automobile braking technology, rapid braking of automobiles is of great significance to reduce traffic accidents. When the car is running on some uneven or soft roads, reducing the tire pressure can protect the tires and improve the maneuverability of the car. The general principle of the deflation system is to press the container on the tire to remove the gas. When the car encounters an emergency and the speed is high, the gas cannot be quickly removed, and the tire pressure cannot be quickly reduced, so that the car cannot stop quickly, causing the car to rear-end or even rush out of the road, which will cause people's lives and property cause serious harm. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the...
