Description

Technical Field

[0001] This invention belongs to the field of airbag impact force testing equipment, specifically a testing device for testing the impact force of automotive airbags. Background Technology

[0002] Car airbags are an important passive safety device. In the event of a collision, the airbag inflates and deploys rapidly, creating a soft buffer zone between the occupants and the hard components of the vehicle. This reduces the risk of injury from direct impact with the steering wheel, dashboard, and other parts of the car. Before use, car airbags undergo impact testing. This involves simulating a collision with the airbag while pressure sensors collect pressure data in real time and transmit it to a data acquisition system. The system processes and analyzes this data to determine key parameters such as the magnitude of the airbag's impact force and its duration of action at different times, thereby assessing whether the airbag's performance meets relevant standards and requirements.

[0003] For example, announcement number CN221445413U discloses an airbag impact force testing device, relating to the field of automotive equipment testing technology. It includes: a test bench; an impact component disposed at one end of the test bench; a sensing unit located at the other end of the test bench; and a support component disposed on the test bench and connected to the impact component. This invention enables impact testing of the airbag shell from multiple angles to obtain impact force data at different angles, providing safety assurance in practical applications and offering low cost.

[0004] For example, CN221465149U discloses an automotive airbag impact testing device, belonging to the field of impact testing technology. The impact testing device includes a testing platform, a first vertical plate fixed above the testing platform, an airbag assembly fixed on the first vertical plate, an impact component for impacting the airbag assembly slidably mounted on the testing platform, and a driving component for driving the impact component to slide on the testing platform. By controlling the lifting height of the hammer head, the hammering force on the second vertical plate is controlled, thereby controlling the moving speed of the second vertical plate, and thus controlling the magnitude of the inertia of the impact component's instantaneous velocity before impact. Therefore, this impact detection can not only detect the magnitude of the impact force that the airbag assembly can deploy, but also the magnitude of the velocity of the first vertical plate before impact. This allows for an approximate simulation of the effect of a human body impacting an airbag under inertia when a vehicle collides with an obstacle, and thus an approximate determination of the vehicle's speed before impact.

[0005] While common car airbag impact testing devices can simulate airbag impacts to evaluate airbag performance, they require multiple tests at different angles, which is inconvenient, time-consuming, labor-intensive, and inefficient. Furthermore, they do not provide a comprehensive assessment of airbag performance and are difficult to use to test airbag performance under different environmental conditions.

Detailed Implementation

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-11As shown, a testing device for testing the impact force of an automotive airbag includes a base 1. A mounting seat 20 is detachably mounted on one side of the upper end of the base 1. An impact cylinder 2 is fixedly mounted at the middle of one end of the mounting seat 20. A square plate 3 is fixedly mounted at the output end of the impact cylinder 2. A first impact plate 4 is detachably mounted at the middle of one end of the square plate 3. Mounting grooves are formed at both ends of the square plate 3. A second impact plate 6 with an adjustable mounting angle is mounted in the mounting grooves via mounting components 5. A first mounting plate 7 is fixedly mounted on the other side of the upper end of the base 1. Sliding grooves 10 are formed on both sides of one end of the first mounting plate 7. A movable T-shaped clamping plate 12 for fixing an airbag 11 is mounted in the sliding grooves 10 via a driving component. A U-shaped clamping plate 12 is fixedly mounted at one end of the T-shaped clamping plate 12. Mounting plate 13, U-shaped mounting plate 13 has a temperature regulating component 8 and a humidity regulating component 9 installed inside. An L-shaped mounting plate 14 is fixedly installed at the middle of the upper end of the first mounting plate 7. An electric telescopic rod 15, distributed horizontally, is installed at one end of the L-shaped mounting plate 14. A baffle 16 is fixedly installed at the output end of the electric telescopic rod 15, with one end extending into the U-shaped mounting plate 13. Temperature sensors 17 and humidity sensors 18 are fixedly installed at both ends of the inner side of the U-shaped mounting plate 13. An integrated control panel 19 is fixedly installed on one side of the first mounting plate 7. Temperature sensors 17 and humidity sensors 18 are electrically connected to the integrated control panel 19. A pressure sensor is installed at one end of the airbag 11. The pressure sensor and the electric telescopic rod 15 are both connected to the integrated control panel 19. Electrically connected, the base 1 has positioning screw holes 21 arranged in a linear array at one end, and the mounting base 20 has positioning screws 22 arranged in a rectangle rotatably mounted at one end, with one end of the positioning screws 22 extending into the positioning screw holes 21. Guide rods 23 are inserted into both sides of one end of the mounting base 20, and one end of the guide rods 23 is fixedly connected to the square plate 3. The drive assembly includes a bidirectional lead screw 24 and a first motor 25. The bidirectional lead screw 24 is rotatably mounted in the sliding groove 10, and the T-shaped clamping plate 12 is threadedly connected to the bidirectional lead screw 24. The first motor 25 is fixedly mounted at one end of the first mounting plate 7, and the output end of the first motor 25 is fixedly connected to the bidirectional lead screw 24. An anti-slip pad is fixedly mounted at one end of the T-shaped clamping plate 12. The first motor 25 is electrically connected to the integrated control panel 19. U-shaped mounting... A square hole 26 is provided at the upper end of plate 13. One end of baffle 16 is inserted into the square hole 26. In use, the first impact plate 4 is installed at the middle position of one end of the square plate 3 by bolts. First, the pressure sensor is installed at the corresponding position of the airbag 11 according to the test position. Then, the drive assembly is activated by the integrated control panel 19 to move the T-shaped clamping plate 12 towards each other in the sliding groove 10 to fix the airbag 11. The rubber anti-slip pad can increase the friction between the T-shaped clamping plate 12 and the airbag 11 and enhance the fixing effect. When a frontal collision of the airbag 11 is required, the second impact plate 6 is manually moved to both sides by the installation assembly 5 to adjust the installation angle of the second impact plate 6 to avoid affecting the impact force test of the first impact plate 4.Then, manually activate the impact cylinder 2 via the integrated control panel 19, moving the square plate 3 and the first impact plate 4 accordingly to impact the airbag 11. The pressure sensor feeds back the pressure information to the integrated control panel 19, which records the pressure information. The performance of the airbag 11 is then observed and recorded. At this time, the guide rod 23 moves inside the mounting base 20, acting as a guide and limiter, ensuring the square plate 3 moves smoothly. When a side impact test is required, manually separate the first impact plate 4 from the square plate 3 using bolts. Then, move the second impact plate 6 inward using the mounting assembly 5, adjusting the installation angle of the second impact plate 6 to the desired measurement angle. Next, attach the pressure sensor to the corresponding position on the airbag 11. Then, manually activate the impact cylinder 2 via the integrated control panel 19, moving the second impact plate 6 to simultaneously impact the side of the airbag 11. The pressure sensor will... Pressure information is fed back to the integrated control panel 19, which records the pressure information, enabling simultaneous impact force testing of the airbag 11 at different angles. This eliminates the need for multiple tests, making it convenient, quick, time-saving, and labor-saving, with high testing efficiency. When it is necessary to adjust the humidity and temperature of the airbag 11's environment, the humidity and temperature inside the U-shaped mounting plate 13 are adjusted via the temperature adjustment component 8 and humidity adjustment component 9. Simultaneously, the moving electric telescopic rod 15 is manually activated via the integrated control panel 19, causing the corresponding baffle 16 to move downwards and into the U-shaped mounting plate 13 through the square hole 26. This guides the flow of moisture, heat, and cold air, ensuring uniform humidity and temperature in the environment surrounding the airbag 11. Then, impact force testing of the airbag 11 is performed, testing the performance of the airbag 11 under different environments, making the airbag 11 testing more comprehensive and ensuring that the airbag 11 meets safety standards.

[0033] like Figure 4As shown, the mounting assembly 5 includes a U-shaped positioning rod 501, a damping telescopic rod 502, and a first spring 503. A second impact plate 6 is hinged in the mounting groove. One end of the second impact plate 6 has positioning holes 504 arranged in a circular array. The U-shaped positioning rod 501 is inserted into both ends of the square plate 3, with both ends extending into the positioning holes 504. Circular grooves are formed on both sides of one end of the square plate 3. One end of the damping telescopic rod 502 is fixedly installed in the circular groove, and the free end of the damping telescopic rod 502 is fixedly connected to the U-shaped positioning rod 501. The first spring 503 is sleeved on the outside of the damping telescopic rod 502, with one end of the first spring 503 fixedly installed in the circular groove. The other end of the first spring 503... One end is fixedly connected to the U-shaped positioning rod 501. When it is necessary to adjust the installation angle of the second impact plate 6 during use, first manually move the U-shaped positioning rod 501 upward so that its two ends are disengaged from the positioning hole 504, thereby releasing the fixing effect on the second impact plate 6. At this time, the damping telescopic rod 502 extends, and the first spring 503 is stretched. Then, manually rotate the second impact plate 6 to the corresponding angle, and then release the U-shaped positioning rod 501. Under the action of the deformation force of the first spring 503, the U-shaped positioning rod 501 automatically resets, and its two ends move into the positioning hole 504 to fix the second impact plate 6, thereby conducting impact force tests on the airbag 11 at different angles.

[0034] like Figure 9As shown, the temperature regulating component 8 includes a mounting block 802 with a square slot 801 at one end, an electric fan 803, and a thermoelectric cooler 804. The mounting block 802 is fixedly mounted on one end of the first mounting plate 7. The electric fan 803 and the thermoelectric cooler 804 are vertically distributed and installed in the square slot 801. A dustproof plate 805 is fixedly installed at one end of the square slot 801. Both the electric fan 803 and the thermoelectric cooler 804 are electrically connected to the integrated control panel 19. Air storage chambers 806 are opened inside both ends of the U-shaped mounting plate 13. Air outlet pipes 807 are symmetrically installed on the inner side of the U-shaped mounting plate 13. One end of the air outlet pipe 807 is connected to the air storage chamber 806. An air supply pipe 808 is fixedly installed on one end of the mounting block 802. Both ends of the air supply pipe 808 are connected to the air storage chamber 806. In use, the thermoelectric cooler 804 is an existing structure that can cool and heat. It can be modified... The direction of the current in the thermoelectric cooler 804 is changed to switch between cooling and heating. First, the left baffle 16 is moved into the U-shaped mounting plate 13. Then, the electric fan 803 and the thermoelectric cooler 804 are manually started through the integrated control panel 19. The thermoelectric cooler 804 generates hot or cold air. The electric fan 803 then delivers the generated hot or cold air to the air storage chamber 806 through the air duct 808, and then sprays it evenly onto the inside of the U-shaped mounting plate 13 through the air outlet duct 807. The baffle 16 acts as a guide. When the temperature sensor 17 detects that the temperature of the environment where the airbag 11 is located reaches the corresponding value, it feeds the information back to the integrated control panel 19. The integrated control panel 19 controls the baffle 16 to move upward to the initial position, then turns off the electric fan 803 and the thermoelectric cooler 804. Finally, the impact force test of the airbag 11 at the corresponding temperature is performed, and the relevant data is recorded.

[0035] like Figure 10 and Figure 11As shown, the humidity control assembly 9 includes an ultrasonic humidifier 901, which is fixedly installed at one end of the first mounting plate 7. The ultrasonic humidifier 901 is electrically connected to the integrated control panel 19. Square cavities 902 are formed inside both ends of the U-shaped mounting plate 13. Spray nozzles 903 are symmetrically installed on the inner side of the U-shaped mounting plate 13, with one end of each nozzle connected to a square cavity 902. An air supply pipe 904 is fixedly installed at the output end of the ultrasonic humidifier 901, with both ends connected to the square cavity 902. In use, the ultrasonic humidifier 901 uses an existing structure; a conventional one can be selected. First, move the baffle 16 located on the right side to the U-shaped mounting plate 7. Inside the airbag 11, the ultrasonic humidifier 901 is manually activated via the integrated control panel 19. The ultrasonic humidifier 901 generates moisture, which is delivered to the square cavity 902 through the air supply pipe 904. The moisture is then evenly sprayed onto the inside of the U-shaped mounting plate 13 through the nozzle 903. The baffle 16 acts as a guide. The nozzle 903 can be an atomizing nozzle series. When the humidity sensor 18 detects that the humidity of the environment where the airbag 11 is located reaches the corresponding value, it feeds the information back to the integrated control panel 19. The integrated control panel 19 controls the baffle 16 to move upward to the initial position, then turns off the ultrasonic humidifier 901. Finally, the impact force test of the airbag 11 under the corresponding humidity is performed, and the relevant data is recorded.
