Description

A honeycomb aluminum mounting structure for deformable barrier in a car side impact test vehicle Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a honeycomb aluminum mounting structure for a deformable barrier in a side-impact test vehicle. Background Technology

[0002] Side impact testing is an important test for evaluating a vehicle's ability to protect occupants and assess the vehicle's structural safety when it is struck from the side. Honeycomb aluminum, as the core material for side impact testing, achieves standardized simulation of real-world collision scenarios through its unique honeycomb structure and aluminum alloy properties. This provides key technical support for evaluating the side safety performance of vehicles. Its design and application have not only driven automakers to optimize vehicle body structure and safety features, but also provided consumers with a scientific basis for choosing safe vehicles.

[0003] Chinese Utility Model Patent Publication No. CN214121554U discloses a collision test fixture based on T-shaped deformation upon impact with a honeycomb aluminum barrier. This fixture has a simple structure, weakens the influence of the test vehicle on the deformation of the honeycomb aluminum barrier during the collision test, and can approximately simulate the T-shaped deformation of the test vehicle impacting the honeycomb aluminum barrier. It can be applied to MPDB high-speed collision tests, reducing costs. Furthermore, the fixture maintains good integrity after high-speed collision impact tests and can be reused. However, this collision test fixture based on T-shaped deformation upon impact with a honeycomb aluminum barrier lacks a honeycomb aluminum mounting structure, making it inconvenient to quickly assemble and disassemble during use. It also lacks a reinforcing structure for the test vehicle body, resulting in low overall stability and robustness, poor practicality, and limited applicability. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a honeycomb aluminum mounting structure for deformable barriers of automobile side collision test vehicles. It can effectively solve the problems of existing technologies that do not have a honeycomb aluminum mounting structure, which is inconvenient to quickly assemble and disassemble during use, and do not have a reinforcing structure for the test vehicle body, resulting in low overall stability and firmness, poor practicality, and difficulty in widespread use.

[0005] The technical solution adopted by this utility model is: a honeycomb aluminum mounting structure for a deformable barrier of a car side collision test vehicle, including a test vehicle body and a mounting frame set at the front end of the test vehicle body. Reinforcing rods one and two are fixedly installed on both sides of the test vehicle body, and reinforcing rod two are fixedly installed at the bottom end of the test vehicle body. A honeycomb aluminum body is set at the end of the mounting frame away from the test vehicle body. A positioning block and a mounting component are fixedly installed at the end of the honeycomb aluminum body near the mounting frame. A through hole three is opened on the outer wall of the mounting component. A positioning groove and a mounting groove are opened at the end of the mounting frame near the honeycomb aluminum body. A fixing block is fixedly installed at the end of the mounting frame near the honeycomb aluminum body. A through hole four is opened on the outer wall of the fixing block. A limiting rod adapted to through hole three and through hole four is inserted into the outer wall of the mounting component.

[0006] Preferably, the reinforcing rod is inclined, and the cross-section of the reinforcing rod and the test vehicle body is triangular. The reinforcing rod is made of high-strength alloy steel.

[0007] The above technical solution, due to the stability of the triangle, enhances the deformation resistance of the test vehicle body by strengthening the design of the reinforcing rod, thereby improving the overall stability and robustness, and has high practicality.

[0008] Preferably, the cross-section of the second reinforcing rod is "X" shaped, and the cross-section of the second reinforcing rod combined with the test vehicle body is "triangular". The second reinforcing rod is made of high-strength alloy steel.

[0009] The above technical solution, due to the stability of the triangle, can effectively improve the structural strength and stability of the bottom of the test vehicle body through the design of the second reinforcing rod, and has high practicality.

[0010] Preferably, the test vehicle body has a guide groove and a through hole one at one end near the mounting frame, an insert block is fixedly installed at one end of the test vehicle body near the mounting frame, a guide block is fixedly installed at one end of the mounting frame near the test vehicle body, a slot is provided at one end of the mounting frame near the test vehicle body, a through hole two is provided on the outer wall of the guide block, a screw adapted to the through hole one and through hole two is inserted and installed at one end of the test vehicle body near the mounting frame, a nut is threadedly connected to the outer edge of the screw, the guide block and the guide groove are inserted and installed, and the insert block and the slot are inserted and installed.

[0011] Using the above technical solution, the staff inserts the guide block into the guide groove and the insert block into the slot, which enables the rapid positioning of the mounting bracket. During the installation process, no complicated calibration operation is required, which can ensure the accurate relative position of the mounting bracket and the test vehicle body, improve installation efficiency, and reduce labor and time costs.

[0012] Preferably, the screw passes through through hole one and through hole two, the diameters of through hole one and through hole two are the same, and the nut abuts against the test vehicle body.

[0013] With the above technical solution, after the mounting bracket is quickly positioned, the staff inserts the screw through the first and second through holes, and then connects the nut to the screw thread, so that the nut abuts against the test vehicle body. This allows for the quick installation of the mounting bracket. During use or assembly, it is easy to quickly disassemble it. When the honeycomb aluminum body is deformed after a collision and is not easy to disassemble, the mounting bracket can be directly disassembled, replaced with a new mounting bracket, and the testing work can continue. It has high practicality.

[0014] Preferably, the mounting component is adapted to the mounting groove, the positioning block and the positioning groove are plugged in, and the cross-section of the mounting component has a "U" shaped structure.

[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:

[0032] As shown in Figures 1-7, the present invention provides a honeycomb aluminum mounting structure for a deformable barrier of a vehicle side collision test vehicle, including a test vehicle body 1 and a mounting frame 2 set at the front end of the test vehicle body 1. Reinforcing rods 1-3 are fixedly installed on both sides of the test vehicle body 1, and reinforcing rods 2-4 are fixedly installed at the bottom end of the test vehicle body 1. A honeycomb aluminum body 13 is set at the end of the mounting frame 2 away from the test vehicle body 1. A positioning block 14 and a mounting component 15 are fixedly installed at the end of the honeycomb aluminum body 13 near the mounting frame 2. A through hole 3-16 is opened on the outer wall of the mounting component 15. A positioning groove 17 and a mounting groove 18 are opened at the end of the mounting frame 2 near the honeycomb aluminum body 13. A fixing block 19 is fixedly installed at the end of the mounting frame 2 near the honeycomb aluminum body 13. A through hole 4-20 is opened on the outer wall of the fixing block 19. A limiting rod 21 adapted to the through hole 3-16 and the through hole 4-20 is inserted into the outer wall of the mounting component 15.

[0033] Specifically, reinforcing rod 3 is inclined, and the cross-section of reinforcing rod 3 combined with the test vehicle body 1 has a triangular structure. Reinforcing rod 3 is made of high-strength alloy steel. The advantage is that, due to the stability of the triangle, the design of reinforcing rod 3 enhances the deformation resistance of the test vehicle body 1, thereby improving the overall stability and robustness, and making it highly practical.

[0034] Specifically, the test vehicle body 1 has a guide groove 5 and a through hole 6 at one end near the mounting bracket 2. An insert block 7 is fixedly installed at the same end of the test vehicle body 1 near the mounting bracket 2. A guide block 8 is fixedly installed at the same end of the mounting bracket 2 near the test vehicle body 1. A slot 9 is provided at the same end of the mounting bracket 2 near the test vehicle body 1. A through hole 10 is provided on the outer wall of the guide block 8. A screw 11, compatible with through holes 6 and 10, is inserted into the same end of the test vehicle body 1 near the mounting bracket 2. A nut 12 is threaded onto the outer edge of the screw 11. The guide block 8 and the guide groove 5 are inserted into each other, as are the insert block 7 and the slot 9. The advantage is that by inserting the guide block 8 into the guide groove 5 and simultaneously inserting the insert block 7 into the slot 9, the mounting bracket 2 can be quickly positioned. During installation, no complex calibration is required, ensuring accurate relative positioning between the mounting bracket 2 and the test vehicle body 1, improving installation efficiency, and reducing labor and time costs.

[0035] Specifically, screw 11 passes through through hole 6 and through hole 10, with the same diameter. Nut 12 abuts against the test vehicle body 1. The advantage is that after quickly positioning the mounting bracket 2, the operator can easily install the mounting bracket 2 by passing screw 11 through through hole 6 and through hole 10, and then thread the nut 12 onto the screw 11, causing the nut 12 to abut against the test vehicle body 1. This allows for quick installation and easy disassembly during use or assembly. If the honeycomb aluminum body 13 deforms after a collision and becomes difficult to disassemble, the mounting bracket 2 can be directly removed, replaced with a new one, and testing can continue. This makes it highly practical.

[0036] Example 2:

[0037] As shown in Figures 2-7, as an improvement on the previous embodiment, to further facilitate the installation of the honeycomb aluminum body 13, specifically, the mounting component 15 is adapted to the mounting groove 18, and the positioning block 14 is plugged into the positioning groove 17. The cross-section of the mounting component 15 has a "U" shape. The advantage is that by inserting the positioning block 14 into the positioning groove 17 and simultaneously inserting the mounting component 15 into the mounting groove 18, the honeycomb aluminum body 13 can be quickly positioned. During installation, no complex calibration operations are required, improving installation efficiency and reducing labor and time costs.

[0038] Specifically, the limiting rod 21 passes through through hole three 16 and through hole four 20, and the diameters of through hole three 16 and through hole four 20 are the same. The advantage is that after the honeycomb aluminum body 13 is quickly positioned, the operator can quickly limit the position of the honeycomb aluminum body 13 by passing the limiting rod 21 through through hole three 16 and through hole four 20. This facilitates quick disassembly during use or assembly, and quick replacement after testing.

[0039] Specifically, the cross-section of reinforcing rod 2 (4) is X-shaped, and the cross-section of reinforcing rod 2 (4) combined with the test vehicle body 1 is triangular. Reinforcing rod 2 (4) is made of high-strength alloy steel. The advantage is that, due to the stability of a triangle, the design of reinforcing rod 2 (4) effectively improves the structural strength and stability of the bottom of the test vehicle body 1, making it highly practical.

[0040] Working principle: During installation, the operator inserts guide block 8 into guide groove 5 and inserts block 7 into slot 9, enabling rapid positioning of mounting bracket 2. During installation, no complex calibration is required, ensuring accurate relative positioning between mounting bracket 2 and test vehicle body 1, improving installation efficiency and reducing labor and time costs. After rapid positioning of mounting bracket 2, the operator inserts screw 11 through through hole 6 and through hole 10, and then threads nut 12 onto screw 11, causing nut 12 to abut against test vehicle body 1, enabling rapid installation of mounting bracket 2. This facilitates quick disassembly during use or assembly. After rapid installation of mounting bracket 2, the operator inserts positioning block 14 into positioning groove 17 and mounting piece 15 into mounting groove 18, enabling rapid positioning of honeycomb aluminum body 13. During installation, no complex calibration operations are required, improving installation efficiency and reducing labor and time costs. After quickly positioning the honeycomb aluminum body 13, the staff can quickly limit the honeycomb aluminum body 13 by passing the limiting rod 21 through the through hole 16 and the through hole 20. This facilitates quick disassembly during use or assembly and quick replacement after testing. If the honeycomb aluminum body 13 is deformed after a collision and difficult to disassemble, the mounting bracket 2 can be directly removed and replaced with a new mounting bracket 2 to continue testing. This makes it highly practical. During use, due to the stability of the triangle, the design of the reinforcing rod 1 3 enhances the deformation resistance of the test vehicle body 1, thereby improving the overall stability and robustness. This also makes it highly practical. The design of the reinforcing rod 2 4 effectively improves the structural strength and stability of the bottom of the test vehicle body 1. This further enhances its practicality.

[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.
