[0016] Example 1

[0017] Please see Figure 1This utility model provides a technical solution: a tool for evaluating remote airbags after a vehicle collision test, including a first evaluation plate 1 and a second evaluation plate 2. The first evaluation plate 1 and the second evaluation plate 2 are the same size and shape, and are rectangular. The top and bottom surfaces of the first evaluation plate 1 are provided with a first fixing groove 6. A corresponding ring 4 is provided in the middle of the surface of the first evaluation plate 1. A corresponding frame 3 is provided on the top of the corresponding ring 4 on the surface of the first evaluation plate 1. The top and bottom surfaces of the second evaluation plate 2 are provided with a second fixing groove 7. A connecting groove 5 is provided inside the first evaluation plate 1, and the second evaluation plate 2 is fitted and slidably connected with the connecting groove 5. The first fixing groove 6 and the second fixing groove 7 are corresponding in position, and are fixedly connected by fixing bolts 8. The bottom center of the corresponding frame 3 is located at the center of the corresponding ring 4. The diameter of the corresponding ring 4 is 40mm, and the corresponding frame 3 is a square frame with a length of 100mm and a width of 20mm. The first evaluation plate 1 and the second evaluation plate 2 are made of transparent material.

[0018] Example 2

[0019] A method for using a tool for remote airbag evaluation after a vehicle crash test includes the following steps:

[0020] Step 1: First, define the corresponding evaluation area, specifically, as follows: Figure 2 The center of gravity of the occupant's head is marked, with the center of gravity located 20mm behind the middle of the seat travel. The evaluation area is a rectangular area enclosed by 120mm above and below the center of gravity, 102mm in front of the center of gravity, and 82mm behind the center of gravity.

[0021] Step 2: Assemble the evaluation tool. Specifically, firstly, calculate the relative distance between the driver's seat and the passenger seat under test conditions. Then, adjust the second evaluation plate 2 with the middle position of the first evaluation plate 1 as the starting point so that the distance between the middle position of the second evaluation plate 2 and the middle position of the first evaluation plate 1 is the same as the relative distance between the driver's seat and the passenger seat calculated above. Finally, fix the first evaluation plate 1 and the second evaluation plate 2 with fixing bolts 8.

[0022] Step 3: Evaluation Rules. Specifically, due to the different shapes of airbags, a single-cavity airbag is defined as a 2D airbag, and an airbag composed of two or more cavities is defined as a 3D airbag. When evaluating a 2D airbag, remove the airbag and lay it flat on a table. Then, align the adjusted evaluation tool with the paint mark on the airbag and check if the inflatable area of ​​the airbag completely covers the evaluation area. If the inflatable area completely covers the evaluation area, it is considered a pass; if the inflatable area does not completely cover the evaluation area, it is considered a fail. When the airbag is a 3D airbag, inflate the airbag and maintain pressure. Adjust the airbag position so that the passenger-side dummy's head just touches the airbag. Then, hold the adjusted evaluation tool directly in front of the airbag and align it with the horizontal level of the airbag. Align the evaluation tool with the paint mark on the airbag, keeping the evaluation tool vertical. If the inflatable area completely covers the evaluation area, it is considered a pass; if the inflatable area does not completely cover the evaluation area, it is considered a fail. In step 3, the paint marks are the paint marks left on the airbag after the collision of the circular and square paint applied to the test dummy's head. When they are superimposed, the corresponding circle 4 corresponds to the circular paint mark, and the corresponding frame 3 corresponds to the square paint mark.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
