Description

A New Type of Automobile Impact Buffer Device

technical field

The utility model relates to the field of systems for ensuring safe driving of automobiles, in particular to an automobile impact buffer device.

Background technique

With the development of society, people's consumption level is gradually increasing, and the number of cars is increasing. In people's daily life, the biggest danger around them is cars. More than 80% of China's road traffic conditions are mixed roads, and China is the world's largest One of the countries with the highest accident death toll. Traffic accidents have become "the world's number one hazard". From the end of the 1980s, the annual death toll in China's traffic accidents exceeded 50,000 for the first time, and now there are 500,000 traffic accidents in China every year, and the number of people killed in traffic accidents every year is more than 100,000, and it is increasing every year. Ranking first in the world for more than ten years, traffic accidents have caused huge losses to people's lives and property. "Cars have a price, but life is priceless." In order to minimize the impact of a car's frontal collision or rear-end collision, and protect the personal and property safety of both parties in the accident, a new type of car impact buffer device is needed.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems, and to provide a buffer device for a frontal collision or a rear-end collision of an automobile. It is achieved through the following technical solutions:

A new type of automobile impact buffer device, including a power module, an ultrasonic distance measuring sensor, an ultrasonic relative speed measuring device, a control ECU, a single-chip microcomputer, a manual switch, a data memory, and an airbag without holes. The input end of described ultrasonic ranging sensor, ultrasonic relative speed measuring device is connected with power supply module by wire, and output end is connected with single-chip microcomputer, and described safety air bag without hole is the improvement of automobile safety air bag, and described data memory and The single-chip microcomputer is connected, and the single-chip microcomputer is connected with the safety air bag through the control ECU, and the device is installed at the front and rear of the vehicle.

The utility model compares the advantages of the prior art:

1. The utility model can timely open the safety airbags installed at the front and rear of the car before the car collides.

2. The utility model adopts the airbag without holes, which can reduce the impact force of the first impact and the second impact of the car, which not only ensures the personal and property safety of both parties in the accident, but also protects pedestrians and other non-accident parties. .

3. The ranging sensor and the relative speed sensor adopted in the utility model can detect the vehicle distance and relative speed more accurately. Moreover, the device is light in weight and small in size, which is conducive to the development of automobiles in the direction of light weight.

4. The safety airbag in the utility model reacts quickly.

5. Use the data memory to store the signal, which is convenient for future inspection and maintenance.

Description of drawings

Fig. 1 is a schematic diagram of the circuit structure of an automobile impact buffer device of the present invention.

detailed description

1-Power supply module; 2-Ultrasonic ranging sensor; 3-Ultrasonic relative speed measuring device; 4-Single-chip microcomputer; 5-Data memory; 6-Control ECU; 7-Safety airbag without holes; switch.

Below in conjunction with embodiment accompanying drawing, the utility model is described further.

As shown in Figure 1, the utility model car impact buffer device includes a power supply module 1, an ultrasonic ranging sensor 2, an ultrasonic relative velocity measuring device 3, a single-chip microcomputer 4, a data memory 5, a control ECU 6, and a safety air bag 7 without holes. , wire 8, manual switch 9 to form. The ultrasonic distance measuring sensor 2 and the ultrasonic relative velocity measuring device 3 transmit signals to the single-chip microcomputer 4, and the single-chip microcomputer 4 signals are stored in the data memory 5 to facilitate future inspection, maintenance and other work. When the distance between the two vehicles is 40cm, the ultrasonic ranging sensor receives the signal, and the ultrasonic relative speed measuring device immediately judges the relative speed of the two vehicles. It is sent to the control ECU, and on the other hand, it is transmitted to the data memory for storage. After the control ECU receives the signal, it controls the airbag without holes to respond quickly. The opened airbag can reduce the impact of the vehicle collision and protect pedestrians and other non-accident parties. Safety, because the utility model patent makes the vehicle equipped with ultrasonic ranging sensors, ultrasonic relative speed measuring devices and safety airbags at the front and rear, so that the vehicle can be protected respectively when it is collided with the front and rear-end.
