[0002] Automobile airbags are a passive safety protection system that work in conjunction with seat belts to provide effective anti-collision protection for occupants when the vehicle collides.

[0003] In order to ensure the quality and safety performance of automobile airbags, automobile airbag tests are usually carried out. These tests include insulation, temperature, humidity tests, mechanical shock tests, drop tests and other tests on automobile airbags. The purpose of these tests is to ensure that automobile airbags can work properly at critical moments and provide effective anti-collision protection for passengers.

[0004] In the drop test, the real working environment of the airbag is simulated when the vehicle falls or collides unexpectedly. The airbag module will be simulated to fall freely from a certain height and direction. Through this simulation, it is possible to detect whether the airbag maintains integrity after falling. Generally, in indoor tests, the airbag is directly dropped on the ground, but the hardness and material of the falling surface will affect the test results, resulting in inaccurate drop test results of the airbag.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 4 As shown, the utility model provides a vehicle airbag component testing device, which includes symmetrically arranged mounting frames 1, with rotating rings 2 distributed at intervals between two mounting frames 1, and drop plates 3 evenly distributed along the circumference between the two rotating rings 2, and a penetrating positioning shaft 16 is provided inside each lifting plate 7, and both ends of the positioning shaft 16 are fixedly connected to the rotating ring 2. The materials between each drop plate 3 are different. By setting drop plates 3 of different materials, different drop surfaces can be simulated in the drop test, thereby improving the accuracy of the drop test data.

[0024] A movably connected support rod 4 is provided on the inner circular wall between the two rotating rings 2, and both ends of the support rod 4 are fixedly connected to the mounting frame 1. The support rod 4 is distributed in a cross shape on the inner circular wall of the rotating ring 2, and the outer wall of the support rod 4 and the inner circular wall of the rotating ring 2 fit each other, so that the rotating ring 2 can realize positioning rotation on the support rod 4.

[0025] The outer circular wall of the rotating ring 2 is provided with evenly distributed gear teeth 5, and a power assembly is provided below the gear teeth 5. The power assembly includes a motor 18 with an external power supply. The motor 18 is installed on the side wall of one of the mounting frames 1. The output shaft of the motor 18 is connected to a main shaft 19 that transversely penetrates the two mounting frames 1. The main shaft 19 is provided with two power gears 20. The power gears 20 are meshed with the gear teeth 5. The rotating ring 2 can be driven to rotate through the power assembly, thereby realizing the rotation of the drop plate 3 made of different materials, completing the automatic rotation, which is simpler and more flexible.

[0026] A mounting plate 6 is provided between the two rotating rings 2, and the two ends of the mounting plate 6 are respectively inserted into the two mounting frames 1, and are fixedly connected to the mounting frames 1. A lifting plate 7 is provided above the mounting plate 6, and a semicircular portion 8 is formed on the top of the lifting plate 7, and a rear inclined portion 9 is formed on the bottom of the lifting plate 7. The inclined portion 9 can be set so that when the sliding wheel 12 slides on the inclined portion 9, the lifting plate 7 can be driven to rise. When the rising heights of the two lifting plates 7 are inconsistent, the angle change of the drop plate 3 can be achieved.

[0027] A cylinder 10 is symmetrically arranged on the top of the mounting plate 6, and the end of the telescopic rod of the cylinder 10 is connected to a fork bar 11, and a movably connected sliding wheel 12 is arranged on the fork bar 11. The wheel surface of the sliding wheel 12 is movably fitted with the inclined portion 9 on the lifting plate 7. The sliding wheel 12 is located between the mounting plate 6 and the lifting plate 7, and when sliding on the mounting plate 6, it is movably fitted with the inclined portion 9, thereby pushing the lifting plate 7 to achieve a change in height.

[0028] A limiting groove 13 is provided on the front end face of the lifting plate 7, and a limiting strip 14 is symmetrically provided on the top of the mounting plate 6. The limiting strip 14 is fixedly connected to the top of the mounting plate 6, and the limiting strip 14 is inserted into the limiting groove 13, thereby ensuring that the lifting plate 7 can achieve vertical height changes without tilting.

[0029] A rear lifting groove 15 is formed at the bottom of each drop plate 3, and the lifting groove 15 cooperates with the semicircular portion 8 on the lifting plate 7, so that when the lifting plate 7 lifts the drop plate 3, the semicircular portion 8 enters the lifting groove 15, thereby better realizing the angle change of the drop plate 3.

[0030] The support rod 4 is provided with a baffle 17, which is movably fitted on the side wall of the rotating ring 2 and fixed on the support rod 4. The baffle 17 can prevent the rotating ring 2 from deviating in the front-to-back direction when rotating on the support rod 4.

[0031] Detailed usage and effects of the above embodiments:

[0032] In the initial state, the two lifting plates 7 prop up the drop plate 3 to ensure that the drop plate 3 is in a horizontal state. The airbag can perform free fall from a high place and fall on the drop plate 3. When it is necessary to drop different materials, the cylinder 10 is controlled to retract the telescopic rod of the cylinder 10, and the sliding wheel 12 is driven to move back through the fork bar 11. The lifting plate 7 falls and the motor 18 is started. The output shaft of the motor 18 drives the main shaft 19 to move, so that the power gear 20 and the gear 5 cooperate with each other, drive the rotating ring 2 to rotate, and the drop plate 3 rotates 90 degrees. After rotation, keep another drop plate 3 of different materials in a horizontal state, so that airbag drop tests of different materials can be carried out.

[0033] When it is necessary to adjust the angle of the drop plate 3, the two cylinders 10 are controlled separately to make the telescopic rods of the two cylinders 10 move forward, and the sliding wheel 12 slides on the inclined portion 9 at the bottom of the mounting plate 6 and the lifting plate 7 by pushing the fork bar 11, so that the lifting plate 7 can be vertically risen. When there is a height difference between the two lifting plates 7, the angle of the drop plate 3 will change when it contacts the drop plate 3, so that the airbag drop test at different angles can be realized by adjusting the angle of the drop plate 3, thereby improving the comprehensiveness of the drop test experimental data.

[0034] 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.
