Description

A quick deflation device for automobile tires

technical field

The utility model belongs to the technical field of tires, in particular to a quick deflation device for automobile tires.

Background technique

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

In order to overcome the shortcomings of the above-mentioned prior art, the purpose of this utility model is to provide a quick deflation device for automobile tires, to make up for the defects that the brake system cannot brake quickly in some emergency situations, and has fast braking and braking effects. nice features.

In order to achieve the above object, the technical solution adopted by the utility model is:

A rapid deflation device for automobile tires, including a microprocessor connected to an LCD display, the microprocessor is located in the instrument panel, and is wirelessly connected to the tire pressure detection device on the wheel hub, and the microprocessor control terminal is connected to the tire control The device is wirelessly connected, and the tire control device is connected to a plurality of air release valves evenly distributed on the wheel hub.

The tire control device is installed in the center of the tire, and the tire control device controls the deflation valve.

The deflation valve is deflated by opening the valve with the tip protruding from the tire control device toward the deflation valve.

The microprocessor communicates wirelessly with the tire pressure detection device to detect the tire pressure at all times; the microprocessor is connected with an LCD display to display the tire pressure.

The LCD display is installed in the driver's cab.

The tire pressure detection device is powered by a rechargeable battery.

The rechargeable battery is charged by a micro-generator installed on the wheel hub.

When deflated, first reduce the tire pressure of the rear two tires, and then reduce the tire pressure of the first two tires.

Compared with the prior art, the utility model evenly installs a plurality of deflation valves on the hub of the wheel, and the microprocessor first judges whether to reduce the tire pressure for emergency braking or to receive a command to reduce the tire pressure from the driver. , if it is a microcontroller, it will send a command to reduce the tire pressure to the tire control device, and at the same time open multiple deflation valves on the wheel hub, first reduce the tire pressure of the last two tires, and then simultaneously Reduce the tire pressure on the front two tires to the same value and bring the car to a quick stop. When the tire pressure is lower than a certain value, the microcontroller sends a command to the tire control device to close the valve.

Description of drawings

Fig. 1 is a schematic diagram of the hardware system of the present invention.

Fig. 2 is a work flow diagram of the utility model.

Detailed ways

The implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and examples.

Referring to Fig. 1, a kind of quick deflation device of automobile tire is characterized in that, comprises the microprocessor 1 that links to each other with LCD display 2, and microprocessor 1 is wirelessly connected with the tire pressure detection device 3 that is located on the wheel hub, and microprocessor 1 The control end of the processor 1 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 .

The tire pressure detection device 3 transmits the tire pressure value signal to the microprocessor 1 after A/D conversion.

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.

The LCD display is installed in the driver's cab so that the driver can check the tire pressure value at any time.

According to the received signal, the microcontroller 1 judges whether an emergency accident requires reducing the tire pressure for emergency braking or whether it has received a command to reduce the tire pressure, and if necessary, it will first report to the rear two tire control devices of the vehicle. Send a command to open multiple deflation valves at the same time, and then send a command to open multiple deflation valves to the front two tire control devices of the vehicle after a short delay.

The tire pressure detection device 3 detects the tire pressure at all times. If the tire pressure is lower than the set value during the deflation process, the microcontroller 1 sends a deflation stop command, and the valve is closed.

The tire control device 4 controls the opening and closing of the deflation valves 5, 6, 7, 8 by extending or shortening the tip according to the command received.

Referring to Fig. 2, the working process of the present utility model is as follows: when the automobile is running normally, when it is judged whether it is an emergency brake or an order to reduce the tire pressure is received, if it is, an order to open and reduce the tire pressure is sent to the tire control device, Reduce the tire pressure of the rear two tires first, and then reduce the tire pressure of the front two tires, so that the car can decelerate and stop smoothly and quickly.
