[0001] This utility model relates to the field of automotive component testing technology, specifically a fixed bracket for testing steering wheel airbags. Background Technology

[0002] The car steering wheel is a very important control component in the whole vehicle, and it is related to most of the car's parts. It is also a component that OEMs attach great importance to in the design. In the design of car steering wheels, in addition to the shape design conforming to ergonomics and matching the shape elements with the vehicle, the design of structure and materials is also very important. Furthermore, the steering wheel airbag is an important structure to protect the driver from injury in accidents such as collisions. In order to ensure the reliability of the steering wheel airbag performance, a lot of testing is required during the production and research and development process. When conducting steering wheel airbag testing, a special fixing bracket is used to fix the steering wheel to simulate its installation state and usage environment in a real vehicle.

[0003] Chinese Utility Model Patent Publication No. CN206177274U discloses an automotive steering wheel testing fixture. This fixture can quickly fix the steering wheel and simultaneously test the overall curvature of the steering wheel, ensuring the safety of the driver during subsequent use. The fixture is convenient to use, has a simple structure, and is suitable for widespread application. However, this automotive steering wheel testing fixture is not convenient for adjusting the angle of a steering wheel containing an airbag, making it difficult to test conditions at different angles. This results in significant limitations in testing and may make it difficult for different drivers to handle different situations, leading to poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fixed bracket for testing steering wheel airbags, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a fixed bracket for testing steering wheel airbags, including a fixed plate, an adjusting seat, an inclined positioning rod, and an airbag steering wheel body are fixedly installed on the top of the fixed plate. A limiting frame and a rotating seat for adjusting the angle are rotatably installed at one end of the adjusting seat near the center line. A rotating rod with a cylindrical cross-section is fixedly installed at the other end of the rotating seat away from the adjusting seat. A positioning seat with an interference fit is inserted into the other end of the positioning rod away from the fixed plate. A slot adapted to the rotating rod is opened at the other end of the positioning seat away from the positioning rod. A limiting cover with a limiting fixation is provided at the other end of the positioning seat away from the positioning rod. A connecting seat is fixedly installed at the other end of the rotating rod away from the adjusting seat. The connecting seat is adapted to the airbag steering wheel body.

[0006] Preferably, a first positioning hole is provided at each of the four corners of the fixing plate, and a second positioning hole is provided at the end of the fixing plate near the center line, wherein the diameter of the first positioning hole is smaller than the diameter of the second positioning hole.

[0007] Through the above technical solution, the design of the first positioning hole and the second positioning hole allows the fixing plate to be installed on the workbench according to the actual situation. It can be fixed by the first positioning hole with a smaller diameter or by the second positioning hole with a larger diameter, or both can be used at the same time, thereby improving the overall stability of the tooling.

[0008] Preferably, an anti-slip pad with a "ring" shaped cross-section is fixedly installed at the other end of the first positioning hole away from the fixing plate, and the anti-slip pad corresponds one-to-one with the first positioning hole.

[0009] The above technical solution, through the design of the anti-slip pad, can increase the contact area between the fixed plate and the workbench, and at the same time increase the friction between the two, which can prevent the fixed plate from easily shifting and prevent the overall support from easily shifting.

[0010] Preferably, a fixing frame is fixedly installed at the other end of the rotating rod away from the adjusting seat, and a through groove is opened at the other end of the fixing frame away from the rotating rod.

[0011] Through the above technical solution, the design of the fixed frame and through groove allows the fixed frame to drive the rotating rod to rotate around the adjusting seat, thereby adjusting the angle between the rotating rod and the fixed plate to adapt to different test conditions.

[0012] Preferably, a pin is fixedly installed at one end of the positioning seat near the positioning rod, and a slot is provided at the other end of the positioning seat near the positioning rod. Both the pin and the slot are adapted to the positioning rod.

[0013] With the above technical solution, after the rotating rod is adjusted to the correct angle, the positioning seat can be inserted into the outer surface of the positioning rod through the insert and slot, which can support the rotating rod and facilitate testing.

[0014] Preferably, a positioning bolt is threaded between the positioning seat and the limiting cover, and two identical positioning bolts are provided, both of which penetrate the positioning seat and the limiting cover.

[0015] With the above technical solution, when providing support, the slot and the rotating rod can be aligned, and then the limiting cover can be placed on the top of the positioning seat. The positioning bolt can be rotated to connect the two, which can not only fix the rotating rod, but also adjust it according to different working conditions, thus improving the versatility of the overall bracket in use.

[0016] Preferably, a connecting post is fixedly installed at one end of the airbag steering wheel body near the connecting seat, and a connecting sleeve is fixedly installed at one end of the connecting seat near the airbag steering wheel body, the connecting sleeve being adapted to the connecting post.

[0017] The above technical solution, through the design of the connecting sleeve and connecting column, allows the airbag steering wheel body to be quickly installed onto the inner surface of the connecting seat. Subsequently, the airbag steering wheel body is tested, which facilitates its quick replacement.

[0018] Compared with the prior art, the present invention provides a fixing bracket for testing steering wheel airbags, which has the following advantages:

[0019] 1. This steering wheel airbag testing mounting bracket, through the design of the fixing frame and through groove, allows the rotating rod to rotate around the adjusting seat via the fixing frame. The angle between the rotating rod and the fixing plate can be adjusted, and the slot can be aligned with the rotating rod. Then, the limiting cover is placed on the top of the positioning seat, and the positioning bolt is rotated to connect the two. This not only fixes the rotating rod but also allows for adjustment according to different working conditions, improving the versatility of the overall bracket in use, facilitating testing, and enabling it to handle the performance of the airbag and steering wheel at different angles, thus improving its practicality.

[0020] 2. The fixed bracket for testing the airbag steering wheel, through the design of the connecting sleeve and connecting column, allows the airbag steering wheel body to be quickly installed onto the inner surface of the connecting seat, and then the airbag steering wheel body can be tested. It can be easily replaced. The anti-slip pad design increases the contact area between the fixed plate and the work surface, and also increases the friction between the two, which can prevent the fixed plate from easily shifting and prevent the overall bracket from easily shifting.

[0030] 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.

[0031] Example 1: As Figure 1-8 As shown, the present invention provides a fixed bracket for testing steering wheel airbags, including a fixed plate 1. An adjusting seat 5, an inclined positioning rod 17, and an airbag steering wheel body 20 are fixedly installed on the top of the fixed plate 1. A limiting frame 6 and a rotating seat 7 for adjusting the angle are rotatably installed at one end of the adjusting seat 5 near the center line. A rotating rod 8 with a cylindrical cross-section is fixedly installed at the other end of the rotating seat 7 away from the adjusting seat 5. A positioning seat 11 with an interference fit is inserted into the other end of the positioning rod 17 away from the fixed plate 1. A slot 14 adapted to the rotating rod 8 is opened at the other end of the positioning seat 11 away from the positioning rod 17. A limiting cover 12 with a limiting fixation is provided at the other end of the positioning seat 11 away from the positioning rod 17. A connecting seat 18 is fixedly installed at the other end of the rotating rod 8 away from the adjusting seat 5. The connecting seat 18 is adapted to the airbag steering wheel body 20.

[0032] Specifically, the fixing plate 1 has first positioning holes 2 at each of its four corners and a second positioning hole 4 at the end of the fixing plate 1 closest to the center line. The diameter of the first positioning hole 2 is smaller than the diameter of the second positioning hole 4. The advantage is that, through the design of the first positioning hole 2 and the second positioning hole 4, the fixing plate 1 can be installed on the workbench according to the actual situation. It can be fixed by using the smaller diameter first positioning hole 2 or the larger diameter second positioning hole 4, or both can be used at the same time, thus improving the overall stability of the tooling.

[0033] Specifically, an anti-slip pad 3 with a "ring" shaped cross-section is fixedly installed at the other end of the first positioning hole 2 away from the fixed plate 1. The anti-slip pad 3 corresponds one-to-one with the first positioning hole 2. The advantage is that the design of the anti-slip pad 3 can increase the contact area between the fixed plate 1 and the workbench surface, and at the same time increase the friction between the two, which can prevent the fixed plate 1 from easily shifting and prevent the overall support from easily shifting.

[0034] Specifically, a fixed frame 9 is fixedly installed at the other end of the rotating rod 8 away from the adjusting seat 5. A through groove 10 is opened at the other end of the fixed frame 9 away from the rotating rod 8. The advantage is that, through the design of the fixed frame 9 and the through groove 10, the rotating rod 8 can be driven to rotate around the adjusting seat 5 through the fixed frame 9, and the angle between the rotating rod 8 and the fixed plate 1 can be adjusted to adapt to different test conditions.

[0035] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a pin 15 is fixedly installed at one end of the positioning seat 11 near the positioning rod 17, and a slot 16 is provided at the other end of the positioning seat 11 near the positioning rod 17. Both the pin 15 and the slot 16 are adapted to the positioning rod 17. The advantage is that after the rotating rod 8 is adjusted to the correct angle, the positioning seat 11 can be inserted into the outer surface of the positioning rod 17 through the pin 15 and the slot 16, which can support the rotating rod 8 and facilitate testing.

[0037] Specifically, a positioning bolt 13 is threadedly connected between the positioning seat 11 and the limiting cover 12. Two identical positioning bolts 13 are provided, and both positioning bolts 13 pass through the positioning seat 11 and the limiting cover 12. The advantage is that when providing support, the slot 14 can be aligned with the rotating rod 8, and then the limiting cover 12 can be placed on top of the positioning seat 11. The positioning bolt 13 can be rotated to connect the two. This can fix the rotating rod 8 and also adjust it according to different working conditions, improving the versatility of the overall bracket in use.

[0038] Specifically, a connecting post 23 is fixedly installed at one end of the airbag steering wheel body 20 near the connecting seat 18, and a connecting sleeve 19 is fixedly installed at one end of the connecting seat 18 near the airbag steering wheel body 20. The connecting sleeve 19 is compatible with the connecting post 23. The advantage is that, through the design of the connecting sleeve 19 and the connecting post 23, the airbag steering wheel body 20 can be quickly installed onto the inner surface of the connecting seat 18, and then the airbag steering wheel body 20 can be tested, which facilitates its quick replacement.

[0039] Working principle: In use, after installing the fixing plate 1 to the test position and adjusting the rotating rod 8 to the required angle, the positioning seat 11 can be inserted into the outer surface of the positioning rod 17 through the insert 15 and slot 16, thereby providing support for the rotating rod 8 and meeting the requirement of stable support for the rotating rod 8 during the test. The positioning seat 11 and the limiting cover 12 are connected by a positioning bolt 13. There are two positioning bolts 13 with the same specifications. Both positioning bolts 13 pass through the positioning seat 11 and the limiting cover 12. When performing the support operation, first align the slot 14 on the positioning seat 11 with the rotating rod 8, then put the limiting cover 12 on the top of the positioning seat 11, and then rotate the positioning bolt 13 to use the threaded connection to firmly connect the positioning seat 11 and the limiting cover 12. This design can not only firmly fix the rotating rod 8, but also adjust it when needed for different working scenarios. The positioning bolt 13 can be removed to reset the relative positions of the positioning seat 11 and the limit cover 12 with the rotating rod 8, and then the positioning bolt 13 can be tightened to complete the fixation. This greatly improves the versatility of the overall bracket in use. The airbag steering wheel body 20 is fixedly installed with a connecting post 23 at one end near the connecting seat 18, while the connecting seat 18 is fixedly installed with a connecting sleeve 19 at one end near the airbag steering wheel body 20. The connecting sleeve 19 and the connecting post 23 are mutually compatible. When installing the airbag steering wheel body 20, the airbag steering wheel body 20 can be quickly installed onto the inner surface of the connecting seat 18 by taking advantage of the compatibility between the connecting sleeve 19 and the connecting post 23. After the current airbag steering wheel body 20 has been tested, it can also be easily removed and replaced with a new airbag steering wheel body 20 for subsequent testing, which significantly improves the replacement efficiency of the airbag steering wheel body 20.

[0040] 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.
