Abstract
Description
Technical Field
[0001] This utility model relates to a simulated collision detection fixture for automotive battery packs, belonging to the field of new energy vehicle testing tooling technology. Background Technology
[0002] With the rapid development of new energy electric vehicles, the task of testing electric vehicle battery packs for collision resistance is becoming increasingly heavy for professional testing institutions. The various battery packs being launched not only undergo multiple tests during the research and development process but also require random sampling inspections within product batches during production. Simulated collision testing of battery packs first requires using clamping fixtures to firmly hold the battery pack onto the test base plate of the fixture. However, the existing clamping fixtures are too complex in structure and have poor adaptability to battery pack shapes and sizes. This not only increases the purchase cost of the fixtures but also increases the operational difficulty during clamping, reducing testing efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is: how to make a clamping fixture with a simple structure, wide adaptability in shape and size, and easy operation.
[0004] To address the above problems, the technical solution proposed by this utility model is as follows: A simulated collision detection fixture for an automotive battery pack includes a platform, a clamping seat, and a screw. The clamping seat includes a base plate and a front side plate. The front side plate is fixed at a right angle to the base plate on the front side of the base plate. The base plate is fixed to the platform. The front side plate has multiple threaded through holes that communicate with each other. The screw is screwed into the threaded through holes and can be screwed forward and backward. The front end of the screw abuts against the side of the battery pack to apply a clamping force to the battery pack.
[0005] A flexible sheath is fitted at the front end of the screw-in screw to protect the area between the front end of the screw-in screw and the side of the battery pack.
[0006] A screw-in handle is provided at the rear end of the screw.
[0007] It also includes a clamping assembly, which includes a support shaft, a pressure bar, a pressure column, and a reverse pressure screw. The support shaft is horizontally mounted on the top of the clamping seat. The pressure bar has a shaft hole in the middle that can pass through the support shaft. The pressure bar is fitted onto the support shaft through the shaft hole and can rotate around the support shaft. The upper end of the pressure column is mounted on the front end of the pressure bar, and its lower end faces downward to press against the top surface of the battery pack. The reverse pressure screw has an external thread, and the rear end of the pressure bar has a vertical threaded through hole II. The reverse pressure screw is screwed into the threaded through hole II and can be screwed downward so that its lower end presses against the platform. When it continues to screw downward after pressing against the platform, it applies an upward force to the rear end of the pressure bar.
[0008] Multiple mounting holes for installing pressure columns are provided longitudinally at the front end of the pressure bar.
[0009] A flexible protective sleeve is fitted at the lower end of the pressure column to cushion the space between the lower end of the pressure column and the top surface of the battery pack.
[0010] A screw-in handle is provided at the upper end of the reverse pressure screw.
[0011] Beneficial effects: This clamp can adapt to battery packs of different sizes and shapes; the battery pack can be clamped from front to back by the screws on the clamping seats at the front and rear, making the inspection clamp very simple, and the operation is very convenient as only the screws need to be turned when clamping.

[0014] The present invention will be further described below with reference to the accompanying drawings: Example 1
[0015] like Figure 1 , 2As shown, a simulated collision detection fixture for an automotive battery pack includes a platform 1, a clamping seat 2, and a screw 3. The clamping seat 2 includes a base plate 201 and a front side plate 202. The front side plate 202 is fixed at a right angle to the base plate 201 on the front side of the base plate 201. The base plate 201 is fixed on the platform 1. The front side plate 202 has multiple threaded through holes 2021 that are connected front and back. The screw 3 is screwed into the threaded through holes 2021 and can be screwed forward and backward. The front end of the screw 3 abuts against the side of the battery pack 5 to apply a clamping force to the battery pack. In application, the clamping seats 2 are fixedly installed at at least at both the front and rear ends of the platform 1, and the clamping seats 2 at both ends of the platform 1 clamp the front and rear sides of the battery pack 5. Since the screw 3 can be screwed forward and backward on the front side plate 202, it can accommodate battery packs 5 of different sizes and side shapes. This testing fixture can clamp the battery pack 5 from front to back using only the screw 3 on the clamping seats 2, making the testing fixture very simple. When clamping, you only need to turn the screw 3, making the operation very convenient.
[0016] If necessary, clamping seats 2 can also be set at the left and right ends of the table 1.
[0017] Furthermore, a flexible sheath 302 is fitted at the front end of the screw 3 to cushion the front end of the screw 3 and the side of the battery pack 5, so as to ensure that the front and rear sides of the battery pack are not damaged.
[0018] Furthermore, a screw-in handle 301 is provided at the rear end of the screw-in screw 3, which makes it easy to turn the screw-in handle 301.
[0019] Preferably, the clamping seat 2 can be fixed to the platform 1 using bolts. Example 2
[0020] like Figure 3 , 4As shown, the difference between this and Embodiment 1 is that the simulated collision detection fixture also includes a clamping assembly 4, which includes a support shaft 401, a pressure bar 402, a pressure column 403, and a reverse pressure screw 404. The support shaft 401 is horizontally mounted on the top of the clamping seat 2. The pressure bar 402 has a shaft hole 4021 in the middle that can pass through the support shaft 401. The pressure bar 402 is fitted onto the support shaft 401 through the shaft hole 4021 and can rotate around the support shaft 401. The upper end of the pressure column 403 is mounted on the front end of the pressure bar 402, and its lower end faces downward to press against the top surface of the battery pack 5. The reverse pressure screw 404 has an external thread, and the rear end of the pressure bar 402 has a vertical threaded through hole 4023. The reverse pressure screw 404 is screwed into the threaded through hole 4023 and can be screwed downward so that its lower end presses against the platform 1. When it continues to screw downward after pressing against the platform 1, it applies an upward force to the rear end of the pressure bar 402. When applied, the reverse pressure screw 404 is screwed down so that its lower end presses against the platform 1. Then, it is screwed down again so that the rear end of the pressure bar 402 is continuously raised while the front end is continuously lowered so that the lower end of the pressure bar presses against the upper surface of the battery pack 5. This prevents the battery pack 5 from jumping up during the collision test.
[0021] Furthermore, a plurality of mounting holes 4022 for mounting the pressure column 403 are provided longitudinally at the front end of the pressure bar 402, so that the pressure column 403 can be installed in different mounting holes 4022 according to the size of the battery pack 5.
[0022] Furthermore, a flexible protective sleeve 4031 is fitted at the lower end of the pressure column 403 to cushion the area between the lower end of the pressure column 403 and the top surface of the battery pack 5, ensuring that the top surface of the battery pack 5 is not damaged.
[0023] Furthermore, a screw-in handle 4041 is provided at the upper end of the reverse pressure screw 404 to facilitate easy turning of the reverse pressure screw 404.
[0024] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
