Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, specifically to an instrument panel collision simulation fixture mounting structure. Background Technology

[0002] In the process of automotive research and development testing, the dashboard, as an important interior component in the cockpit, is a key part of vehicle safety testing, with its collision safety, such as its protective performance for occupants during a collision, its own structural impact resistance, and its synergistic effect with components such as airbags. To verify the performance of the dashboard under collision conditions, the industry widely uses collision simulation fixtures to fix replicas or real vehicle dashboards, and uses impact devices such as pendulums, sleds, and airbag deployment devices to simulate collision scenarios and obtain relevant test data. Therefore, the installation of these fixtures is an indispensable part of automotive testing.

[0003] In existing technologies, tooling fixtures are often one-piece structures. Although they can serve the purpose of fixing and testing, they are not designed with multiple alignment structures, which makes it easy for misalignment to occur during installation. This makes the installation process more complicated, and the use of one-piece counterweights further increases the difficulty of transportation, thus hindering widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an installation structure for a collision simulation tooling rack for an instrument panel. It can effectively solve the problems in the prior art, which does not have a multi-alignment structure, resulting in misalignment of the tooling rack during installation. As a result, the installation operation is relatively cumbersome, and the use of integrated counterweights often increases the difficulty of transportation, making it inconvenient for widespread use.

[0005] The technical solution adopted by this utility model is: an instrument panel collision simulation tooling mounting structure, including a base frame, a front support rod and a rear support rod, an mounting frame is fixedly installed at the end of the base frame away from the front support rod and the rear support rod, a counterweight is placed at the inner edge of the mounting frame, and a top frame assembly is fixedly installed at the end of the rear support rod away from the base frame;

[0006] The top frame assembly includes a fixing rod 1, a connecting rod 1 and a connecting rod 2 are fixedly installed at one end of the fixing rod 1, a fixing rod 2 is fixedly installed between the connecting rods 2, and a positioning bolt 3 is threadedly connected to the connection point of the connecting rods 1 and 2 near the fixing rod 1.

[0007] Preferably, fixing posts are fixedly installed at both ends of the fixing rod one near the connecting rod one and the connecting rod two, and the fixing rod one is connected to the front support rod through the fixing posts.

[0008] Through the above technical solution, the design of the fixed column facilitates quick positioning of the fixed rod and the front support rod when connecting them, which is convenient for subsequent fixing. It also enhances the stability of the top frame assembly after installation and avoids shaking of the top during collision simulation.

[0009] Preferably, a reserved groove is provided at one end of the base frame near the mounting frame, and mounting blocks are fixedly installed at the four corners of the mounting frame. The reserved groove corresponds to the mounting block, and a positioning bolt is threadedly connected to the inner edge of the mounting block. The positioning bolt passes through the base frame and extends to the inner edge of the mounting block.

[0010] Through the above technical solution, by designing the pre-reserved slot and the mounting block, when installing the counterweight, the pre-reserved slot can be aligned with the mounting block, which can realize the quick alignment of the counterweight and the base frame, facilitate the quick installation between the two, facilitate the disassembly of the counterweight, and at the same time play a stabilizing role for the base frame, which can prevent it from easily tipping over.

[0011] Preferably, there are two identical pre-reserved slots, mounting blocks, mounting frames, and counterweights, and the two pre-reserved slots, mounting blocks, mounting frames, and counterweights are symmetrically distributed about the center line of the base frame.

[0012] Through the above technical solution, the design of two reserved slots, mounting blocks, mounting frames and counterweights allows counterweights to be installed at both the front and rear ends of the base frame. Gravity balance can offset the force on one side, avoiding the problem of the base frame tilting and tipping over during collision simulation, thereby improving its stability.

[0013] Preferably, a reserved groove 2 is provided at one end of the base frame near the rear support rod, and an insert block is fixedly installed at one end of the rear support rod near the reserved groove 2, with the reserved groove 2 and the insert block corresponding to each other.

[0014] Through the above technical solution, by designing the second reserved slot, when installing the support rod, the insert block can be inserted into the second reserved slot, which can achieve quick alignment, facilitate subsequent welding and other operations, avoid displacement during fixing, and simplify the installation steps.

[0015] Preferably, the rear support rod is threaded with a connecting bolt one and a connecting bolt two at the end away from the top frame assembly. The connecting bolt one and the connecting bolt two pass through the rear support rod and extend to the inner edge of the top frame assembly. The front support rod is threaded with a positioning bolt two at the outer edge.

[0016] The above technical solution uses connecting bolt 1 and connecting bolt 2 to lock the rear support rod to the top frame assembly, and positioning bolt 2 to fix the height or position of the front support rod, forming a multi-node fixing structure. This can improve the overall rigidity of the tooling frame, withstand greater impact forces, and facilitate its quick assembly and disassembly.

[0017] Preferably, a support rod one is welded between the front support rod and the rear support rod, a support rod two is welded between the rear support rod and the base frame, a reinforcing frame is fixedly installed at the end of the base frame away from the rear support rod, and a reinforcing rod with an "X" shaped cross-section is fixedly installed along the inner edge of the reinforcing frame.

[0018] The above technical solution connects the front and rear support rods and the base frame through support rod one and support rod two, respectively, forming a triangular stable structure. The "X"-shaped reinforcing rod enhances the deformation resistance of the reinforcing frame, further improving the deformation resistance of the base frame and preventing deformation caused by excessive local stress.

[0019] Compared with the prior art, this utility model provides an instrument panel collision simulation tooling mounting structure, which has the following beneficial effects:

[0020] The instrument panel collision simulation fixture installation structure, through the design of reserved slot 2, front and rear support rods, and multiple connecting bolts and positioning bolts, allows for the rapid installation of the entire fixture and the selection and replacement of different parts according to the actual situation. However, the lack of an alignment structure makes it easy for misalignment to occur during fixing, resulting in a cumbersome installation process and making it inconvenient for widespread use.

[0021] 2. The instrument panel collision simulation fixture installation structure, through the design of the reserved slot and the mounting block, allows the reserved slot to be aligned with the mounting block when installing the counterweight, enabling quick alignment of the counterweight and the base frame. This facilitates rapid installation between the two and easy disassembly of the counterweight. At the same time, it also stabilizes the base frame and prevents it from easily tipping over.

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.

[0030] Example 1: As Figure 1-6 As shown, the present invention provides an instrument panel collision simulation tooling mounting structure, including a base frame 1, a front support rod 9 and a rear support rod 13. An mounting frame 4 is fixedly installed at the end of the base frame 1 away from the front support rod 9 and the rear support rod 13. A counterweight block 5 is placed at the inner edge of the mounting frame 4. A top frame assembly 14 is fixedly installed at the end of the rear support rod 13 away from the base frame 1.

[0031] The top frame assembly 14 includes a fixing rod 1401, a connecting rod 1402 and a connecting rod 2 1403 fixedly installed at one end of the fixing rod 1401, a fixing rod 2 1404 fixedly installed between the connecting rods 2 1403, and a positioning bolt 3 1405 threadedly connected to the connection point of the connecting rods 1402 and the connecting rod 2 1403 near the fixing rod 1401.

[0032] Specifically, fixing posts 1406 are fixedly installed at both ends of fixing rod 1401 near connecting rod 1402 and connecting rod 2 1403. Fixing rod 1401 is connected to front support rod 9 through fixing posts 1406. The advantage is that the design of fixing posts 1406 makes it easy to quickly position fixing rod 1401 and front support rod 9, which is convenient for subsequent fixing. It also enhances the stability of the top frame assembly 14 after installation and avoids shaking of the top during collision simulation.

[0033] Specifically, a reserved slot 2 is provided at one end of the base frame 1 near the mounting frame 4. Mounting blocks 3 are fixedly installed at the four corners of the mounting frame 4. The reserved slot 2 corresponds to the mounting block 3. A positioning bolt 6 is threadedly connected to the inner edge of the mounting block 3. The positioning bolt 6 passes through the base frame 1 and extends to the inner edge of the mounting block 3. The advantage is that, through the design of the reserved slot 2 and the mounting block 3, when installing the counterweight 5, the reserved slot 2 can be aligned with the mounting block 3, which can realize the quick alignment of the counterweight 5 and the base frame 1. It can facilitate the quick installation between the two and the removal of the counterweight 5. At the same time, it can also play a stabilizing role for the base frame 1 and prevent it from easily tipping over.

[0034] Specifically, there are two identical pre-reserved slots 2, mounting blocks 3, mounting frames 4, and counterweights 5. The two pre-reserved slots 2, mounting blocks 3, mounting frames 4, and counterweights 5 are symmetrically distributed about the center line of the base frame 1. The advantage is that, through the design of the two pre-reserved slots 2, mounting blocks 3, mounting frames 4, and counterweights 5, counterweights 5 can be installed at both the front and rear ends of the base frame 1. The force on one side can be offset by gravity balance, avoiding the problem of the base frame 1 easily tilting and tipping over during collision simulation, thereby improving its stability.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, a reserved groove 2 11 is provided at one end of the base frame 1 near the rear support rod 13, and an insert block 12 is fixedly installed at one end of the rear support rod 13 near the reserved groove 2 11. The reserved groove 2 11 and the insert block 12 correspond to each other. The advantage is that, through the design of the reserved groove 2 11, when installing the rear support rod 13, the insert block 12 can be inserted into the reserved groove 2 11, which can play a role in quick alignment, facilitate subsequent welding and other operations, avoid displacement during fixing, and simplify the installation steps.

[0037] Specifically, the rear support rod 13 is threaded with connecting bolt 15 and connecting bolt 2 16 at the end away from the top frame assembly 14. Connecting bolt 15 and connecting bolt 2 16 pass through the rear support rod 13 and extend to the inner edge of the top frame assembly 14. The front support rod 9 is threaded with positioning bolt 2 10 at the outer edge. The advantage is that the rear support rod 13 and the top frame assembly 14 are locked together by connecting bolt 15 and connecting bolt 2 16, and the positioning bolt 2 10 fixes the height or position of the front support rod 9, forming a multi-node fixing structure. This can improve the overall rigidity of the tooling frame, withstand greater impact forces, and facilitate quick assembly and disassembly.

[0038] Specifically, a support rod 17 is welded between the front support rod 9 and the rear support rod 13, and a support rod 2 18 is welded between the rear support rod 13 and the base frame 1. A reinforcing frame 7 is fixedly installed at the end of the base frame 1 away from the rear support rod 13. A reinforcing rod 8 with an "X" shaped cross-section is fixedly installed at the inner edge of the reinforcing frame 7. The advantage is that the front and rear support rods 13 and the base frame 1 are connected by the support rod 17 and the support rod 2 18 respectively, forming a triangular stable structure. Furthermore, the "X" shaped reinforcing rod 8 enhances the deformation resistance of the reinforcing frame 7, further improving the deformation resistance of the base frame 1 and preventing deformation caused by excessive local stress.

[0039] Working Principle: During use, the design of the fixing column 1406 facilitates quick positioning of the connecting fixing rod 1401 and the front support rod 9, enabling subsequent fixing and enhancing the stability of the top frame assembly 14 after installation, preventing top swaying during collision simulations. The design of the pre-reserved slot 2 and mounting block 3 allows for quick alignment of the counterweight 5 with the base frame 1 when installing the counterweight 5, facilitating rapid installation and disassembly of the counterweight 5. It also stabilizes the base frame 1, preventing it from easily tipping over. The design of the two pre-reserved slots 2, mounting block 3, mounting frame 4, and counterweight 5 allows for the installation of counterweights 5 at both the front and rear ends of the base frame 1. Gravity balance counteracts unilateral forces, preventing the base frame 1 from tilting and tipping over during collision simulations. To improve its stability, the design of the pre-reserved slot 2 11 allows the insert block 12 to be inserted into the pre-reserved slot 2 11 when installing the rear support rod 13, which can quickly align the rod and facilitate subsequent welding operations. This avoids displacement during fixing and simplifies the installation process. The rear support rod 13 is locked to the top frame assembly 14 by connecting bolt 1 15 and connecting bolt 2 16, and the positioning bolt 2 10 fixes the height or position of the front support rod 9, forming a multi-node fixing structure. This improves the overall rigidity of the tooling frame, enabling it to withstand greater impact forces and facilitating quick assembly and disassembly. The support rod 1 17 and support rod 2 18 connect the front and rear support rods 13 and the base frame 1 respectively, forming a triangular stable structure. Furthermore, the "X"-shaped reinforcing rod 8 enhances the deformation resistance of the reinforcing frame 7, further improving the deformation resistance of the base frame 1 and preventing deformation caused by excessive local stress.
