Description

Technical Field

[0001] The utility model relates to the technical field of automobile anti-collision beams, in particular to an automobile anti-collision warning airbag structure. Background Art

[0002] The anti-collision beam is a device used to reduce the impact energy when the vehicle is hit. It consists of a main beam, an energy absorption box, and a mounting plate connected to the car. The main beam and the energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body, thereby playing a protective role on the vehicle.

[0003] The common automobile anti-collision structure design is mostly to install only one airbag structure on the anti-collision beam, which is used to provide anti-collision buffering effect for the anti-collision beam. When the collision pressure is too large, a single airbag is difficult to provide sufficient buffering force, and the mounting plate structure behind the anti-collision beam will also be subject to a certain collision pressure, resulting in structural damage. Therefore, this solution provides an automobile anti-collision warning airbag structure for the single airbag of the anti-collision beam, which improves the utilization rate of the air in the airbag and enhances the anti-collision buffering effect.

[0022] The automobile pressure sensor 3 is installed on the second airbag component 5 , and the sensing probe end of the automobile pressure sensor 3 is located inside the second airbag component 5 .

[0023] The intake pipe 2 is externally connected to an air pump, and the vehicle control system assembly is electrically connected to the air pump externally connected to the intake pipe 2, the vehicle pressure sensor 3, and the cylinder 10 respectively. The external air pump is located inside the vehicle, and the vehicle control system assembly controls the external air pump to replenish air for the first airbag component 4 through the intake pipe 2. After receiving the signal from the vehicle pressure sensor 3 through the vehicle control system assembly, the vehicle control system assembly controls the cylinder 10 on the back panel 6 to work, so as to release the gas in the second airbag component 5.

[0024] A piston plate 801 is provided at the air inlet port connecting the spring valve 8 and the first airbag component 4. The back of the piston plate 801 is fixed to the inner wall of the valve through a spring rod 802. The top air outlet port of the spring valve 8 passes through the upper beam plate 101 and is connected to the air guide pipe 7. The spring valve 8 is used to realize the function of inputting gas into the second airbag component 5 when the first airbag component 4 is subjected to a large collision pressure, and the secondary buffering effect is realized through the second airbag component 5.

[0025] The first airbag component 4 is a strip-shaped cylindrical airbag, and the outer surface of the first airbag component 4 protrudes from the upper beam plate 101 and the lower beam plate 102. The second airbag component 5 is a compression segmented sleeve airbag component, and the end of the toggle rod 12 is provided with a round plug cover corresponding to the exhaust port 9; the first airbag component 4 is used to provide a collision buffering effect for the anti-collision beam 1, and the second airbag component 5 is used to provide a buffering effect at the back plate 6 after the anti-collision beam 1 is hit, so as to avoid damage to the structure of the back plate 6 due to excessive pressure after the anti-collision beam 1 is hit, and the whole structure is installed on the car through a fixing plate behind the back plate 6;

[0026] Under normal conditions, the circular plug cover at the end of the toggle rod 12 is embedded in the exhaust port 9. When deflation is required, the cylinder 10 works and the toggle rod 12 is pulled to move under the action of the telescopic shaft of the cylinder 10, so that the circular plug cover at the end of the toggle rod 12 is pulled out from the exhaust port 9, thereby achieving the effect of deflation of the second airbag component 5 after the cover is opened.

[0027] Working principle:

[0028] In this solution, the automobile pressure sensor and the automobile control system assembly are both publicly available products and corresponding technologies in the market, and are only used for signal reception and control functions of the drive structure in this solution. For example, the automobile pressure sensor is of models such as ZMPT101B and MPX5100. The automobile pressure sensor is used to monitor whether the air pressure in the second airbag component 5 is full. If it is full, the automobile control system assembly needs to control the cylinder 10 to work, so that excess air in the second airbag component 5 can be released to avoid damage caused by excessive inflation of the second airbag component 5.

[0029] In the present solution, under normal conditions, the first airbag component 4 is in an inflated state, and the second airbag component 5 is in an airless state. When the car collides, the first airbag component 4 is squeezed, thereby pushing the piston plate 801 at the end of the air inlet in the spring valve 8. At this time, the gas in the first airbag component 4 passes through the spring valve 8 and enters the second airbag component 5 from the air guide pipe 7. The car pressure sensor 3 on the second airbag component 5 generates air pressure changes, and after transmitting the data signal to the car control system assembly, it is displayed on the display screen installed in the car. At the same time, the car control system assembly controls the air pump in the car to work, and the air is replenished into the first airbag component 4 through the air intake pipe 2 again;

[0030] Under normal conditions, there is no air inside the second airbag component 5. After the first airbag component 4 is squeezed and collided, the air enters the second airbag component 5 after passing through the spring valve 8 and the air guide tube 7, thereby adding the buffering force effect at the anti-collision beam 1 between the anti-collision beam 1 and the back plate 6, that is, providing a buffering force effect for the second airbag component 5, reducing the possibility of damage to the back plate 6 due to collision. When the first airbag component 4 has been subjected to multiple collisions, its air is squeezed and input into the second airbag component 5 to form a filled state. After detection by the automobile pressure sensor 3, the automobile control system assembly controls the cylinder 10 to work. The cylinder 10 pulls the splint 13 through the telescopic shaft. The toggle rod 12 is sleeved and penetrated in the splint 13. The toggle rod 12 is pulled so that the circular plug cover at the end of the toggle rod 12 is detached from the exhaust port 9, allowing the excess air in the second airbag component 5 to be released, thereby avoiding damage caused by excessive inflation in the second airbag component 5; the first airbag component 4 can quantitatively input a corresponding amount of air through an air pump connected to the intake pipe 2.

[0031] After the air in the first airbag component 4 enters the second airbag component 5 from the spring valve 8 through the air guide pipe 7, the piston plate 801 in the spring valve 8 is reset by the spring rod 802, thereby closing the valve inlet port;

[0032] After the air in the second airbag component 5 is deflated from the exhaust port 9 through the above steps, the cylinder 10 stops working and the toggle rod 12 is reset by the reset spring 14, so that the circular plug cover at the end of the toggle rod 12 is embedded in the exhaust port 9 again, thereby completing the blocking effect of the second airbag component 5.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
