Abstract
Description
Technical Field
[0001] The utility model belongs to the field of vehicle tests, and particularly relates to a double-airbag blasting test device for simulating the real vehicle environment. Background Art
[0002] The airbag system is a passive safety protection system. When used in conjunction with the seat belt, it can provide effective anti-collision protection for the occupants. Currently, in order to improve the safety performance of the driver's seat in a car, some high-end sedans are equipped with three airbags around the driver's seat. One airbag is installed inside the steering wheel to protect the driver's chest and head during a violent impact of the vehicle. Side airbags are installed on both sides of the seat backrest. The bilateral airbags can effectively reduce the damage caused by side impacts to the driver.
[0003] During the seat development process, in order to verify whether the blasting state of the bilateral airbags meets the design requirements, it is necessary to simultaneously detonate the bilateral airbags in the real vehicle environment. However, during the development stage, the resources of the vehicle body and the environmental components inside the vehicle body are relatively scarce and the cost is very high. Therefore, there is an urgent need for a test device that can simulate the real vehicle environment and meet the requirements of the double-airbag blasting test. Summary of the Utility Model
[0004] The utility model provides a double-airbag blasting test device for simulating the real vehicle environment. The test device can simulate the real vehicle environment and is equipped with vehicle body components and environmental components inside the vehicle body related to the double-airbag blasting test according to the position relationship of the real vehicle. Therefore, it can replace the vehicle body and the environmental components inside the vehicle body to conduct the double-airbag blasting test, solving the problems of relatively scarce resources of the vehicle body and the internal environmental components and high cost.
[0005] To achieve the above object, the utility model provides a double-airbag blasting test device for simulating the real vehicle environment, including a fixed bottom plate. A baffle is connected to the fixed bottom plate through a fixed frame. On one side of the baffle, a main seat back clamping structure, a simulated central armrest, and a secondary seat back clamping structure are arranged in sequence. The main seat back clamping structure is used for installing the driver's seat backrest, and the secondary seat back clamping structure is used for installing the co-driver's seat backrest.
[0006] As a further optimization, a plurality of mounting holes are uniformly arranged on the fixed bottom plate. The fixed frame, the main seat back clamping structure, the simulated central armrest, and the secondary seat back clamping structure are all detachably connected to the fixed bottom plate by bolts passing through the mounting holes.
[0007] As a further optimization, the fixing frame includes a bottom plate, on which there are at least two laterally arranged first adjustment holes. On both longitudinal sides of the bottom plate, there are adjustment plates, on which there are longitudinally arranged second adjustment holes. The baffle can move laterally relative to the fixed bottom plate through the first adjustment holes, and the baffle can move longitudinally relative to the bottom plate through the second adjustment holes. The baffle is arranged on one side of the fixing frame close to the main seat back clamping structure, and there are support rods between the baffle and the two side adjustment plates.
[0008] The main seat back clamping structure and the secondary seat back clamping structure have the same structure, including a connecting plate. The middle of the connecting plate has a weight reduction hole, and there are multiple first connecting holes on both longitudinal sides of the weight reduction hole. On both lateral sides of the connecting plate, there are connecting arms, and the connecting arms have second connecting holes. The seat back is connected to the main seat back clamping structure and the secondary seat back clamping structure through the second connecting holes.
[0009] Advantages and beneficial effects of the present utility model
[0010] 1. A baffle is installed on the top of the fixed bottom plate of the present utility model, and the baffle is used to simulate the car door in the actual vehicle environment. On one side of the baffle, there are successively arranged a main seat back clamping structure, a simulated central armrest, and a secondary seat back clamping structure. The main seat back clamping structure is used to fix the driver's seat back, the simulated central armrest is used to simulate the central armrest in the actual vehicle environment, and the secondary seat back clamping structure is used to fix the passenger seat back. Therefore, through this test device, the front row environment of the actual vehicle can be simulated, solving the problems of tight resources of the vehicle body and internal environment parts and high costs during the development stage, which is beneficial to accelerating the development progress of the seat and saving costs.
[0011] 2. The baffle in the present utility model is arranged on the top of the fixed bottom plate through the fixing frame, and the baffle can be moved laterally and longitudinally through the first adjustment holes and the second adjustment holes on the fixing frame. Therefore, the distance between the baffle and the main seat back clamping structure can be adjusted according to different vehicle models. The main and secondary seat back clamping structures and the simulated central armrest are all detachably connected to the fixed bottom plate through bolts. Therefore, they can be replaced according to different vehicle models, so the universality of this application is stronger. Description of the drawings

The base plate 21 is connected to the fixed base plate 1 by inserting bolts into the first adjustment holes 22 and the mounting holes 11 on the fixed base plate 1. The baffle 3 can be moved transversely relative to the fixed base plate 1 through the first adjustment holes 22. Adjustment plates 23 are provided on both longitudinal sides of the base plate 21, and second adjustment holes 24 are provided on the adjustment plates 23. The adjustment plates 23 are connected to the base plate 21 by inserting bolts into the second adjustment holes 24 and the through holes on the base plate 21. The adjustment plates 23 and the baffle 3 connected to the adjustment plates 23 can be moved longitudinally relative to the base plate 21 through the second adjustment holes 24. A baffle 3 is provided on one side of the adjustment plates 23 on both sides close to the main seat back clamping structure 4, and a support rod 25 is provided between the baffle 3 and the adjustment plate 23. The support rod 25 plays a role in supporting the baffle 3.
[0020] like Figure 1 As shown, the side of the baffle 3 facing away from the fixing frame 2 is provided with a main seat back clamping structure 4, a simulated central armrest 5 and a secondary seat back clamping structure 6 in sequence. The main seat back clamping structure 4 is used to install the main driver's seat back, the simulated central armrest 5 is used to simulate the central armrest in the actual vehicle environment, and the secondary seat back clamping structure 6 is used to install the secondary driver's seat back. The main seat back clamping structure 4 and the secondary seat back clamping structure 6 have the same structure and include a connecting plate 41. The middle part of the connecting plate 41 is provided with a connecting plate 41. It is provided with a weight-reducing hole 42, and the longitudinal sides of the weight-reducing hole 42 are provided with multiple first connecting holes. The main seat back clamping structure 4 and the auxiliary seat back clamping structure 6 are both detachably connected to the top of the fixed base plate 1 by bolts passing through the first connecting holes and the mounting holes 11 on the fixed base plate 1. The lateral sides of the connecting plate 41 are provided with connecting arms 43, and the connecting arms 43 are provided with second connecting holes 44.

[0021] Dual airbag explosion test
[0022] This application mainly tests the dual airbag explosion test on both sides of the main seat back, wherein the baffle 3 is equivalent to the door in the actual vehicle environment, the simulated center armrest 5 is equivalent to the center armrest in the actual vehicle environment, and the auxiliary seat back clamping structure 6 is used to install the auxiliary seat back. The baffle 3 is a body component related to the airbag explosion test on one side of the main seat back, and the simulated center armrest 5 and the auxiliary seat back are environmental parts related to the airbag explosion test on the other side of the main seat back.
[0023] Before the test, it is necessary to install the main seat back clamping structure 4, the simulated center armrest 5 and the secondary seat back clamping structure 6 that match the vehicle model to be measured, and adjust the distance between the baffle 3 and the main seat back clamping structure 4 according to the vehicle model to be measured. Then, install the test device on the trolley, install the main seat back on the main seat back clamping structure 4, and install the secondary seat back on the secondary seat back clamping structure 6. Then, push the application to the temperature chamber by the trolley for the airbag blasting test. After that, an external signal for blasting is given to the bilateral airbags to inflate and blast the double airbags on both sides of the main seat back. When the left airbag inflates and blasts, it will contact the baffle 3, and when the right airbag inflates and blasts, it will contact the simulated center armrest 5 and the secondary seat back on the secondary seat back clamping structure 6, thereby simulating the front row environment of the actual vehicle body when the double airbags inflate and blast. The blasting state of the bilateral airbags is detected by the outer contour after the left airbag contacts the baffle 3 and the outer contour after the right airbag contacts the simulated center armrest 5 and the secondary seat back to check whether it meets the design requirements. At the same time, the airbag blasting test can be carried out at high temperature, normal temperature and low temperature respectively through the temperature chamber to verify the blasting performance of the airbag at different temperatures.
