Description

Technical Field

[0001] This utility model relates to the technical field of battery device testing equipment, and more specifically, to a fixing device for battery simulated collision testing. Background Technology

[0002] As a core component of electric vehicles, the battery pack needs to possess excellent shock resistance, impact resistance, and collision resistance to ensure the safe and stable operation of the electric vehicle. To ensure the high safety and stability of the battery pack installed in the electric vehicle, various performance tests need to be conducted on individual battery packs, such as shock resistance tests, impact resistance tests, and collision resistance tests.

[0003] Currently, the common method for securing battery devices is to use a pressure plate structure to simply mount them onto various test benches for performance testing. Specifically, the battery device is placed on the test bench, a pressure plate is used to hold it in place, and then bolts are used to detachably connect the pressure plate to the test bench. However, this type of test bench installation is mostly unidirectional, lacking the capability for X-axis and Y-axis simulated collisions. This results in a limited collision testing range, reduced accuracy, and hinders subsequent testing. Furthermore, the installation process is time-consuming and labor-intensive, reducing efficiency. Additionally, issues arise where bolts protrude from the platform; for larger power batteries, the sample may encounter the bolts with no adjustment space, making installation impossible. A battery simulation collision testing fixing device is needed to solve this problem. Utility Model Content

[0023] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example

[0024] refer to Figures 1 to 2Example 1 describes a slide 1 with a first positioning hole 2. A first sample mounting platform 3 and a second sample mounting platform 17 can be mounted on the slide 1 as needed. Both the first sample mounting platform 3 and the second sample mounting platform 17 have recessed locking holes 6. A first conversion platform 8 and a second conversion platform 18 are mounted on the first sample mounting platform 3 and the second sample mounting platform 17, respectively. A transfer platform 20 is mounted on one side of the first conversion platform 8 and the second conversion platform 18. A first power battery mounting clamping plate 10 and a second power battery mounting clamping plate 19 are mounted on the first conversion platform 8 and the second conversion platform 18, respectively. Both the first power battery mounting clamping plate 10 and the second power battery mounting clamping plate 19 are equipped with… The system is equipped with multiple L-shaped frames 13, with a power battery 15 installed at the bottom of each L-shaped frame 13. A hexagonal socket head cap screw 7 is installed on a recessed locking hole 6, and the hexagonal socket head cap screw 7 is compatible with the recessed locking hole 6. A first limit bolt hole 4 and a second limit bolt hole 5 are respectively provided on the first sample mounting platform 3 and the second sample mounting platform 17. The first limit bolt hole 4 and the second limit bolt hole 5 have sizes of M16 and M12, respectively. A third positioning hole 11 is provided on the first power battery mounting clamping plate 10 and the second power battery mounting clamping plate 19. The third positioning hole 11 has sizes of M16 and M12, respectively. The thickness of the adapter platform 20 is greater than the height of the protruding hexagonal socket head cap screw 7 on the first sample mounting platform 3 and the second sample mounting platform 17.

[0025] In this embodiment, the first sample mounting platform 3 of the fixing device is provided with a groove-shaped locking hole 6, which is locked to the trolley 1 by an internal hex bolt 7. The internal hex bolt 7 is installed in the groove-shaped locking hole 6. After installation, the first sample mounting platform 3 can be installed on the trolley 1 at multiple angles according to the needs of use, and the installation will not be blocked by the protrusion of the internal hex bolt 7. Example

[0026] refer to Figures 2 to 3 Example 2 further illustrates Example 1, including a power battery 15 with protrusions 16 at three corners, a fixing bolt 14 on an L-shaped frame 13, and a locking hole on the protrusion 16 locking the fixing bolt 14. A second positioning hole 9 is installed on a first conversion platform 8, and the second positioning hole 9 is bolted to a positioning bolt 12 on a first power battery mounting clamping plate 10. A third positioning hole 11 is provided on the first power battery mounting clamping plate 10, and the third positioning hole 11 is threaded to the L-shaped frame 13. A first sample fixing hole 21, a second sample fixing hole 22, and a third sample fixing hole 23 are respectively installed on a transfer platform 20.

[0027] In this embodiment, the fixing bolts 14 on the L-shaped frame 13 fix the protrusions 16 at three locations of the power battery 15, thereby achieving stable clamping of the power battery 15 and ensuring the stability of the power battery 15 during subsequent collision tests.

[0028] In practical applications, the fixing device of this utility model is equipped with a trolley 1, the bottom of which is mounted on a track. The trolley 1 is launched using an additional launching device to simulate various test conditions. Traditional battery collision simulation tests generally require X-axis testing but cannot perform Y-axis testing on the power battery 15, lacking multi-directional collision testing capabilities, resulting in a small test range and reduced test accuracy. This utility model achieves X-axis and Y-axis testing by launching the trolley 1 using a launching device.

The hexagon socket head cap screw 7 is installed in the recessed locking hole 6. After installation, the hexagon socket head cap screw 7 sinks and does not protrude from the surface of the trolley 1, allowing the first sample mounting platform 3 to be mounted on the trolley 1 at multiple angles as needed without being obstructed by the protrusion of the hexagon socket head cap screw 7. Similarly, the first sample fixing hole 21 on the adapter platform 20 is a stepped hole, which is fixed to the first sample mounting platform 3 by a hexagon socket head cap screw 7. After installation, the hexagon socket head cap screw 7 sinks and does not protrude from the surface of the adapter platform 20. The first conversion platform 8 can be installed in different positions according to different collision tests. With the adapter platform 20, it can stably connect to the first power battery mounting clamping plate 10, so that the power battery 15 at the bottom of the L-shaped frame 13 on the first power battery mounting clamping plate 10 can be stably tested, thereby improving the accuracy of the test results.
