Description

A bracket mounting structure for testing car seat belts Technical Field

[0001] This utility model relates to the field of automotive seat belt testing technology, specifically to a bracket mounting structure for automotive seat belt testing. Background Technology

[0002] Car seat belt testing is a crucial step in ensuring passenger safety. It aims to verify the strength, reliability, and protective performance of seat belts for occupants by simulating stress conditions in real-world scenarios. The tests cover static load tests (such as locking force and tensile strength testing) and dynamic crash tests (simulating the restraint effect during sudden braking or impact). Specialized equipment is required to simulate different working conditions. In these tests, the car seat belt testing bracket is an indispensable core support structure. It is usually made of high-strength metal materials and has stability.

[0003] Most existing car seat belt testing brackets are directly welded together to form an integral structure. This structure has strong impact and deformation resistance and is suitable for withstanding high dynamic loads. However, once the welding is completed, the structure cannot be adjusted and is difficult to adapt to different testing requirements (such as different car models or different seat belt models). Repairing or replacing parts requires cutting, which affects the overall structural strength. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bracket mounting structure for testing automotive seat belts, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a bracket installation structure for testing automotive seat belts, including a test vehicle and a support frame, as well as a first connecting plate and a second connecting plate located on the top of the test vehicle. A seat bracket is provided on the top of the first and second connecting plates. A guide seat is fixedly installed at the top end of the first connecting plate away from the seat bracket. A positioning block is fixedly installed at the center of the guide seat near the seat bracket. An installation groove is formed at the end of the seat bracket near the guide seat. Fixing plates are symmetrically installed on the top side of the first connecting plate away from the seat bracket. A fixing block is fixedly installed on the top of each of the two sets of fixing plates. The second fixed plate has two sets of mounting plates with slidably connected inner sides. A fixing member is rotatably mounted on the outer surface of each mounting plate. A reinforcing plate is fixedly mounted on the end of the mounting plate away from the fixing member. A groove is formed on the end of the reinforcing plate away from the first connecting plate. A protrusion is provided on the side of the reinforcing plate near the first connecting plate. A slot is formed on the side of the protrusion away from the first connecting plate. A winding device is provided on the side of the reinforcing plate away from the mounting plate. A slider is fixedly mounted on the end of the winding device near the reinforcing plate. An insert is fixedly mounted on the end of the winding device near the first connecting plate. A locking screw is provided on the side of the winding device away from the reinforcing plate.

[0006] Preferably, the end of the seat bracket away from the test vehicle is fixedly mounted with a car seat body, a hand-tightening screw is provided on the side of the seat bracket away from the test vehicle, and the end of the first connecting plate away from the test vehicle is provided with a mounting hole for threaded connection with the hand-tightening screw.

[0007] Preferably, the hand-tightening screws and mounting holes are provided in four identical sets, and the four sets of hand-tightening screws and mounting holes are symmetrically distributed along the center line of the first connecting plate.

[0008] The above technical solution strengthens the connection between the seat bracket and the first connecting plate by using hand-tightened screws and threaded connections in the mounting holes. Furthermore, the design of hand-tightened screws eliminates the need for external tools when installing the seat bracket, thus improving assembly and disassembly efficiency.

[0009] Preferably, a rotating component is rotatably mounted on the outer surface of the mounting plate, and a latch is rotatably connected to the side of the rotating component away from the first connecting plate. A locking tongue is fastened to the end of the latch away from the first connecting plate. A movable frame is slidably mounted on the outer surface of the support frame. A hanging ring tilt bracket is provided on the side of the movable frame near the seat bracket. A seat belt hanging ring is fixedly mounted on the outer surface of the hanging ring tilt bracket. A guide is fixedly mounted on the surface of the seat belt hanging ring. A vehicle seat belt is provided inside the latch, the fixing component, the retractor, and the guide.

[0010] Through the above technical solution, the rotating component serves as a rotational pivot, allowing the buckle to rotate at multiple angles to simulate the dynamic torsion of the seat belt during a collision. The buckle and the locking tongue form a connection structure that can be quickly released. The tension direction of the test seat belt can be adjusted by the sliding connection of the movable frame on the support frame.

[0011] Preferably, the guide seat and the seat bracket have the same cross-section, the seat bracket and the guide seat are plugged in, and the positioning block and the mounting groove are plugged in.

[0012] Through the above technical solution, the same cross section of the guide seat and the seat bracket forms a self-guiding structure, which automatically corrects the angle deviation when inserted. After entering the mounting groove through the positioning block, a secondary correction is achieved, which improves the positional accuracy. When adapting to seats of different models, only the seat bracket assembly with matching cross section needs to be replaced.

[0013] Preferably, the reinforcing plate and the slider are slidably connected by a groove, the insert block and the protrusion are connected by a slot, and the reinforcing plate and the winding device are fixedly installed by locking screws.

[0014] The above technical solution involves first connecting the winding device to the reinforcing plate via a slider along the groove until the insert is fully inserted into the slot, thus achieving a quick connection between the winding device and the reinforcing plate. Then, the winding device and the reinforcing plate are fixed by tightening screws.

[0015] Preferably, a clamping member is fixedly installed on the top of the second connecting plate, and a rack is fixedly installed on the top of the seat bracket near the second connecting plate, with the clamping member and the rack being engaged.

[0016] With the above technical solution, after the seat bracket is installed, the clamping component is fixed to the top of the second connecting plate with bolts and meshes with the rack. The meshing connection between the clamping component and the rack increases the friction between the seat bracket and the second connecting plate, ensuring the stability of the seat bracket during the crash test.

[0017] Compared with the prior art, the present invention provides a bracket mounting structure for testing automotive seat belts, which has the following advantages:

[0018] 1. The mounting structure for the car seat seat belt testing bracket forms a self-guiding structure by using the same cross-section of the guide seat and the seat bracket. It automatically corrects the angle deviation during insertion, and then achieves secondary correction after entering the mounting slot through the positioning block, thereby improving the positional accuracy. When adapting to different car seat models, only the seat bracket assembly with matching cross-section needs to be replaced. Subsequently, four sets of symmetrically distributed hand-tightening screws provide quick locking to ensure that the bracket does not loosen during testing. The design of the hand-tightening screws also eliminates the need for external tools when installing the seat bracket, thereby improving the efficiency of disassembly and assembly.

[0019] 2. The mounting structure for the car seat seat belt test bracket connects the retractor to the reinforcing plate via a slider along the slide groove until the aforementioned insert is fully inserted into the slot, thus achieving a quick connection between the retractor and the reinforcing plate. Subsequently, the retractor and the reinforcing plate are fixed by locking screws, and the reinforcing plate and locking screws prevent the structure from loosening during testing.

The outer surface of the mounting plate 16 is rotatably mounted with a fixing member 20. The end of the mounting plate 16 away from the fixing member 20 is fixedly mounted with a reinforcing plate 21. The end of the reinforcing plate 21 away from the first connecting plate 3 is provided with a sliding groove 22.

The side of the protrusion 23 away from the first connecting plate 3 is provided with a slot 24. The side of the reinforcing plate 21 away from the mounting plate 16 is provided with a winding device 25. The end of the winding device 25 near the reinforcing plate 21 is fixedly mounted with a slider 26. The end of the winding device 25 near the first connecting plate 3 is fixedly mounted with an insert block 27. The side of the winding device 25 away from the reinforcing plate 21 is provided with a locking screw 28.

[0033] Specifically, the seat bracket 5 is fixedly installed with the car seat body 6 at the end away from the test vehicle 1, and a hand screw 10 is provided on the side of the seat bracket 5 away from the test vehicle 1. The first connecting plate 3 is provided with a mounting hole 11 at the end away from the test vehicle 1, which is threadedly connected to the hand screw 10.

[0034] Specifically, four sets of identical hand-tightening screws 10 and mounting holes 11 are provided, and the four sets of hand-tightening screws 10 and mounting holes 11 are symmetrically distributed along the center line of the first connecting plate 3. The advantage is that the threaded connection between the hand-tightening screws 10 and the mounting holes 11 strengthens the connection between the seat bracket 5 and the first connecting plate 3. Furthermore, the design of the hand-tightening screws 10 eliminates the need for external tools when installing the seat bracket 5, thus improving assembly and disassembly efficiency.

[0035] Specifically, a rotating component 17 is rotatably mounted on the outer surface of the mounting plate 16. A latch 18 is rotatably connected to the side of the rotating component 17 away from the first connecting plate 3.

The advantage is that the rotating component 17 acts as a rotation hub, allowing the latch 18 to rotate at multiple angles, simulating the dynamic torsion of the seat belt during a collision. The latch 18 and the latch 19 form a connection structure that can be quickly released. The tension direction of the test seat belt can be adjusted through the sliding connection of the movable frame 29 on the support frame 2.

[0036] Example 2: As shown in Figure 2-10, this is an improvement on the previous example.

[0037] Specifically, the guide seat 7 and the seat bracket 5 have the same cross-section, and the seat bracket 5 and the guide seat 7 are plug-in installed. The positioning block 8 and the mounting groove 9 are also plug-in connected. The advantage is that the identical cross-section of the guide seat 7 and the seat bracket 5 forms a self-guiding structure, which automatically corrects the angle deviation during insertion. Then, after entering the mounting groove 9 through the positioning block 8, a secondary correction is achieved, improving the positional accuracy. When adapting to seats of different models, only the seat bracket 5 assembly with a matching cross-section needs to be replaced.

[0038] Specifically, the reinforcing plate 21 and the slider 26 are slidably connected via the slide groove 22, the insert block 27 and the protrusion 23 are connected via the slot 24, and the reinforcing plate 21 and the winding device 25 are fixedly installed via the locking screw 28. The advantage is that the winding device 25 is first connected to the reinforcing plate 21 via the slider 26 along the slide groove 22 until the insert block 27 is fully inserted into the slot 24, thus achieving a quick connection between the winding device 25 and the reinforcing plate 21. Then, the winding device 25 and the reinforcing plate 21 are fixed together via the locking screw 28.

The clamping member 13 and the rack 12 are meshed together. The advantage is that after the seat bracket 5 is installed, the clamping member 13 is fixedly installed on the top of the second connecting plate 4 with bolts and meshes with the rack 12. The meshing connection between the clamping member 13 and the rack 12 increases the friction between the seat bracket 5 and the second connecting plate 4, ensuring the stability of the seat bracket 5 during crash testing.

[0040] Working principle: During use, the guide seat 7 and the seat bracket 5 form a self-guiding structure with the same cross-section, automatically correcting the angle deviation during insertion. Then, after entering the mounting slot 9 through the positioning block 8, a secondary correction is achieved, improving the positional accuracy. When adapting to seats of different models, only the seat bracket 5 assembly with a matching cross-section needs to be replaced. Subsequently, four sets of symmetrically distributed hand-tightening screws 10 provide quick locking, ensuring that the bracket does not loosen during testing. The design of the hand-tightening screws 10 eliminates the need for external tools when installing the seat bracket 5, thus improving disassembly and assembly efficiency. After the seat bracket 5 is installed, the position of the fixing plate 14 is manually adjusted, and then the reinforcing plate 21 is... The bolts are fixedly installed on the mounting plate 16. First, the retractor 25 is connected to the reinforcing plate 21 along the slide groove 22 via the slider 26 until the above-mentioned insert 27 is fully inserted into the slot 24, which can realize the quick connection between the retractor 25 and the reinforcing plate 21. Then, the retractor 25 and the reinforcing plate 21 are fixed by the locking screw 28. The rotating part 17 serves as a rotation hub, allowing the buckle 18 to rotate at multiple angles to simulate the dynamic torsion of the seat belt during a collision. The buckle 18 and the locking tongue 19 form a connection structure that can be quickly released to simulate the force on the seat belt buckle during a collision and test its anti-torsion and anti-pull-out performance. The tension direction of the test seat belt can be adjusted by the sliding connection of the moving frame 29 on the support frame 2.

[0041] 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.
