Description

Technical Field

[0001] This utility model relates to the technical field of automotive seat airbag testing equipment, and in particular to a deployment testing fixture for automotive seat airbags. Background Technology

[0002] With the continuous improvement of automotive safety performance, car seat airbags, as one of the important devices for improving occupant passive safety, have made the reliability testing of their deployment performance a critical step in the automotive research and development and production process. To ensure that airbags can deploy quickly and stably under actual collision conditions, researchers typically conduct deployment tests in a laboratory environment. To achieve repeatable and high-precision testing results, it is necessary to use a reasonably structured and easy-to-operate testing fixture to install and adjust the airbags, thereby simulating their deployment states under different actual conditions.

[0003] In existing technologies, common airbag deployment testing fixtures typically consist of a base, mounting plate, support frame, and threaded fastening structure. The airbag's position and angle are adjusted manually using adjustable components. Most of these structures rely on simple threaded connections or sliding fits to achieve relative movement between components. Their adjustment principle is based on mechanical screw drives or sliding rail guidance. Some fixtures utilize hinge mechanisms to rotate the support arm during angle adjustment to simulate airbag deployment at different seat installation angles. However, these structures generally suffer from cumbersome adjustment procedures, insufficient positioning accuracy, or susceptibility to structural rotation under stress, severely impacting testing efficiency and repeatability.

[0004] However, existing testing fixtures generally lack flexible adjustment capabilities when faced with differences in seat structure or multi-angle arrangement requirements. Especially during airbag deployment tests at different angles, the sleeve structure of the device is difficult to position stably and is prone to displacement as the threaded rod rotates, resulting in the inability to accurately adjust the angle of the support structure. This limitation not only increases the operational difficulty but also restricts the versatility and convenience of the test, reduces overall testing efficiency, and cannot effectively meet the need for rapid verification of deployment conditions for multiple seat airbag models. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a testing fixture for the deployment of automotive seat airbags, aiming to improve the inconvenience of testing airbags at different installation angles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a test fixture for the deployment of an automotive seat airbag, comprising a fixed plate, a support assembly at the bottom of the fixed plate, a bracket two fixedly connected to the outer wall of the fixed plate, a drive assembly on one side of the bracket two, an adjustment assembly at the top of the bracket two, and a support plate rotatably connected to the top of the fixed plate.

[0007] The adjustment assembly includes a threaded rod rotatably connected to the top of the second bracket. A sleeve is threadedly connected to the outer wall of the threaded rod. A support rod is rotatably connected to the top of the sleeve. A connecting block is rotatably connected to one end of the support rod. One side of the connecting block is fixedly connected to one side of the support plate. Limit grooves are formed inside both the fixed plate and the second bracket. A limit block is fixedly connected to the bottom of the sleeve. The limit block is slidably connected inside the limit groove.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, the outer wall of which is fixedly connected to one side of the bracket, and the output end of the motor is connected to one end of the threaded rod.

[0010] As a further description of the above technical solution:

[0011] The support assembly includes a bracket, the top of which is connected to the bottom of the fixed plate.

[0012] As a further description of the above technical solution:

[0013] An adjustment block is fixedly connected to the other side of the support plate, and an adjustment groove is provided inside the adjustment block.

[0014] As a further description of the above technical solution:

[0015] The adjusting block has a slider 1 inside, which is slidably connected inside the adjusting groove, and a connecting seat is fixedly connected to one side of the slider 1.

[0016] As a further description of the above technical solution:

[0017] The slider has a groove inside and a hand-tightening bolt is threaded inside.

[0018] As a further description of the above technical solution:

[0019] One end of the hand-tightening bolt is rotatably connected to a slider two, and a locking block is fixedly connected to the outer wall of the slider two. The locking block is slidably connected inside the groove.

[0020] As a further description of the above technical solution:

[0021] The slider is internally connected to a connecting plate, and an anti-slip strip is fixedly connected to the outside of the connecting plate. One side of the anti-slip strip is in contact with the inner wall of the adjustment groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, firstly, the bottom of the sleeve is limited in the limiting groove by the limiting block, which prevents the sleeve from rotating with the threaded rod. The sleeve slides on the outer wall of the threaded rod and drives the connection between the support rod and the connecting block to drive the support plate to rotate around the connection of the fixed plate as the center. This achieves the effect of easy angle adjustment and solves the problem that the airbag deployment test fixture is inconvenient to test at different angles. This improves the convenience of the airbag deployment test fixture.

[0024] 2. In this utility model, after slider one is in place, simply rotate the hand-tightening bolt. The hand-tightening bolt drives slider two to extend into the interior of slider one. Then, the outer wall of slider two abuts against one side of the connecting plate through the outer wall of the locking block, so that the other side of the connecting plate is locked to slider one by the anti-slip strip against the inner wall of the adjustment groove. This achieves the effect of adapting to different sizes of seat airbags, solves the problem of inconvenience when installing airbags of different models and sizes in the airbag deployment test fixture, and improves the practicality of the airbag deployment test fixture.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a test fixture for the deployment of an automotive seat airbag, comprising a fixed plate 1, which serves as the mounting reference surface for the entire test fixture, providing a stable support foundation. A support assembly is provided at the bottom of the fixed plate 1 to enhance the stability and vibration resistance of the overall structure. A bracket 4 is fixedly connected to the outer wall of the fixed plate 1, which is used to install and support an adjustment assembly and a drive assembly, ensuring stable operation during work. A drive assembly is provided on one side of the bracket 4, providing power input to a threaded rod 6 for automated adjustment. An adjustment assembly is provided at the top of the bracket 4, adjusting the angle of a support plate 3 to accommodate different seat installation angles. The support plate 3 is rotatably connected to the top of the fixed plate 1, serving as the bearing surface for airbag installation; its rotatable connection facilitates angle adjustment according to actual test requirements.

[0034] The adjustment assembly includes a threaded rod 6, which is rotatably connected to the top of the bracket 4. The threaded rod 6 drives the outer sleeve 7 to move axially via rotation, thereby adjusting the angle of the support plate 3. The sleeve 7 is threadedly connected to the outer wall of the threaded rod 6, and the sleeve 7 can slide along the threaded rod 6 under threaded engagement, achieving position adjustment. A support rod 9 is rotatably connected to the top of the sleeve 7. The support rod 9 transmits the movement to the connecting block 10 when the position of the sleeve 7 changes, thereby driving the support plate 3 to rotate. One end of the support rod 9 is rotatably connected to the connecting block 10, which establishes the force transmission connection between the support rod 9 and the support plate 3, ensuring precise adjustment. One side of the connecting block 10 is fixedly connected to one side of the support plate 3, ultimately transmitting the adjustment movement to the support plate 3, thereby achieving angle changes in the support plate 3. Limited openings are provided inside both the fixed plate 1 and the bracket 4. The groove 21 is used to constrain the movement direction of the sleeve 7 and prevent it from shifting as the threaded rod 6 rotates. The bottom of the sleeve 7 is fixedly connected to a limiting block 8, which slides within the limiting groove 21 to ensure that the sleeve 7 only moves axially during adjustment and does not rotate, thereby improving the stability and accuracy of adjustment. The driving component includes a motor 5, the outer wall of which is fixedly connected to one side of the bracket 2 4, serving as a power source to drive the threaded rod 6 to rotate. The output end of the motor 5 is connected to one end of the threaded rod 6, and the automatic rotation of the threaded rod 6 is achieved through transmission, improving adjustment efficiency and reducing the burden of manual operation. The support component includes a bracket 1 2, the top of which is connected to the bottom of the fixed plate 1 to provide vertical structural support, enhance the overall rigidity and load-bearing capacity of the device, and ensure that the test fixture remains stable and does not deform under load.

[0035] Reference Figure 4 and Figure 5An adjusting block 11 is fixedly connected to the other side of the support plate 3. The adjusting block 11 is used to install a sliding adjustment mechanism, which facilitates fine-tuning of the installation position during seat airbag installation to adapt to different airbag models. An adjusting groove 12 is provided inside the adjusting block 11, which provides a sliding trajectory for the slider 13, enabling the slider 13 to move along the adjustment direction, thereby realizing the lateral adjustment function of the structure. The adjusting block 11 contains a slider 13, which slides in the adjusting groove 12 as an adjustable component to change the position of the connecting seat 15 on the adjusting block 11, thereby adjusting the installation position of the airbag to adapt to different installation requirements. The slider 13 slides... Connected inside the adjustment groove 12, this connection method ensures that slider 13 can slide smoothly along the direction of the adjustment groove 12, facilitating continuous and controllable adjustment. A connecting seat 15 is fixedly connected to one side of slider 13. The connecting seat 15 is used to install or position the airbag installation assembly and is a key component for connecting the airbag structure during the test, ensuring installation reliability. A sliding groove 14 is provided inside slider 13, providing a sliding channel for slider 2 16, realizing the guiding and limiting functions of slider 2 16, ensuring that it moves only within a set direction. A hand-tightening bolt 18 is threaded inside slider 13, used to control the entry and exit position of slider 2 16, operated manually by rotation. The second slider 16 can move precisely along the slide groove 14 to achieve the limiting and fixing operation of the connecting plate 19; one end of the hand-tightening bolt 18 is rotatably connected to the second slider 16. The second slider 16 moves in conjunction with the hand-tightening bolt 18 to realize the extension and retraction of the internal locking structure, thereby pushing the locking block 17 to cooperate with the connecting plate 19, achieving the effect of locking the first slider 13; the locking block 17 is fixedly connected to the outer wall of the second slider 16. The locking block 17 acts as a limiting component. When the second slider 16 extends, it can abut against the side of the connecting plate 19 to achieve lateral stop, thereby fixing the position of the first slider 13 and preventing it from shifting during the test; the locking block 17 is slidably connected inside the slide groove 14. The sliding connection method ensures that the locking block 13 is properly positioned. Block 17 maintains guiding accuracy in the slide groove 14, improving locking stability. A connecting plate 19 is slidably connected inside the slider 13. The connecting plate 19 is used to enhance the force-bearing area of ​​the slider structure and works in conjunction with the anti-slip strip 20 for the final locking function, improving the overall positioning capability of the structure. The anti-slip strip 20 is fixedly connected to the outside of the connecting plate 19. The anti-slip strip 20 increases the friction with the inner wall of the adjustment groove 12, preventing the slider 13 from moving due to force in the locked state. One side of the anti-slip strip 20 is in contact with the inner wall of the adjustment groove 12. This contact relationship ensures that the adjustment block 11 has anti-slip capability when locked, thereby improving the reliability and adaptability of the entire device during installation and testing.

[0036] Working principle: When using this car seat airbag deployment test fixture, firstly adjust the position of slider 13 to adapt to airbags of different sizes. Slider 13 slides in the adjusting block 11. When slider 13 is in place, simply turn the hand-tightening bolt 18. The hand-tightening bolt 18 drives slider 2 16 to extend into the interior of slider 13. Then, the outer wall of slider 2 16 abuts against one side of the connecting plate 19 through the outer wall of the locking block 17, so that the other side of the connecting plate 19 is attached to the inner wall of the adjusting groove 12 through the anti-slip strip 20 to lock slider 13. Then, the airbag is fixed to slider 13 through the connecting seat 15, thus achieving the effect of adapting to seat airbags of different sizes.

[0037] When the angle of the support plate 3 needs to be adjusted, the output end of the motor 5 drives the threaded rod 6 to rotate. Since the bottom of the sleeve 7 is limited in the limiting groove 21 by the limiting block 8, the sleeve 7 is prevented from rotating with the threaded rod 6. Then the sleeve 7 slides on the outer wall of the threaded rod 6 and drives the connection between the support rod 9 and the connecting block 10 to drive the support plate 3 to rotate around the connection of the fixed plate 1, thus achieving the effect of easy angle adjustment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
