[0002] As a core component of electric vehicles, battery devices need to possess excellent earthquake resistance, shock resistance, collision resistance and other properties to ensure the safe and stable operation of electric vehicles. To ensure the high safety and stability of battery devices installed in electric vehicles, various performance tests need to be carried out on individual battery devices, such as earthquake resistance performance tests, shock resistance performance tests, or collision resistance performance tests, etc.

[0003] Currently, the battery device is usually simply installed on each test bench by using a pressing plate structure to fix the battery device, so that the test bench can perform performance tests on the battery device. Specifically, first place the battery device on the test bench, then use a pressing plate to press on the battery device, and then detachably connect the pressing plate to the test bench through bolts to install the battery device on the test bench. However, most of these test benches installed on the platform are unidirectional installation collisions, and cannot be disassembled and assembled for X-direction simulated collision and Y-direction simulated collision, and do not have the function of multi-directional collision testing, resulting in a smaller range of collision testing, reducing the accuracy of the test, being not conducive to the next step of testing, and being time-consuming and laborious during the installation process, reducing work efficiency. In addition, when encountering bolts protruding from the platform and installing large-sized power batteries, the sample will touch the bolts and there is no adjustment space, resulting in inability to install.

[0026] In this embodiment, the groove-type locking hole 6 is provided on the fixed device first sample mounting platform 3 and is locked on the pulley 1 through the internal hexagon bolt 7.

[0027] Embodiment 2

[0028] Reference From Figure 2 to Figure 3 Description of Embodiment 2, this embodiment further describes Embodiment 1, including a power battery 15. Protrusion parts 16 are installed at three corners of the power battery 15. A fixing bolt 14 is installed on the L-shaped frame 13, and the limit hole on the protrusion part 16 is locked with the fixing bolt 14.

[0030] In specific applications, a trolley 1 is installed on the fixing device provided by the present invention. The bottom of the trolley 1 is installed on the track, and the trolley 1 is launched through an additional launching device to simulate various test conditions. In traditional battery simulation collision tests, generally only X-direction tests are carried out, and it is impossible to perform Y-direction tests on the power battery 15, lacking the function of multi-directional collision tests, resulting in a smaller range of collision tests and reducing the accuracy of the tests.

A groove-shaped locking hole 6 is provided on the first sample mounting platform 3 of the fixing device, and is locked to the trolley 1 through an internal hexagonal bolt 7. The internal hexagonal bolt 7 is installed in the groove-shaped locking hole 6. After installation, the internal hexagonal bolt 7 sinks and does not protrude from the surface of the trolley 1, enabling the first sample mounting platform 3 to be mounted on the trolley 1 at various angles according to the usage requirements, without being blocked by the protruding internal hexagonal bolt 7 during installation. Similarly, the first sample fixing hole 21 on the adapter platform 20 is a stepped hole and is fixed to the first sample mounting platform 3 through an internal hexagonal bolt 7. After installation, the internal hexagonal bolt 7 sinks and does not protrude from the surface of the adapter platform 20. The first conversion platform 8 provided can be installed at different positions according to collision tests in different directions, and in cooperation with the setting of the adapter platform 20, can stably connect the first power battery 15 mounting and clamping plate 10, facilitating stable testing of the power battery 15 at the bottom end of the L-shaped frame 13 on the first power battery 15 mounting and clamping plate 10, thereby improving the accuracy of the test results.
