[0032] The test box body 500 is used to assemble batteries, and the vibration component 110 is arranged below the test box body 500. Each vibration rod 700 of the vibration component 110 is controlled individually, and multiple vibration rods 700 hit the test box body 500 in a disorderly manner. Since the test box body 500 is fixed by the elastic component 120, the elastic component 120 can further amplify such vibration, thereby simulating the disordered and irregular vibration environment of the battery in actual use.

[0033] The upper support frame 200 can be fixed on a wall or other fixed objects, or the upper support frame 200 includes a frame body, which is fixed on the ground by the frame body, thereby achieving the suspension fixation of the test box body 500.

[0036] Four vibration rods 700 are correspondingly arranged at the four corners of the test box body 500; in order to prevent the test box body 500 from being damaged when the vibration rod 700 hits the test box body 500; a rubber ball 800 is arranged on the upper end of the vibration rod 700, and the vibration rod 700 hits the test box body 500 through the rubber ball 800.

[0037] In an optional embodiment, a mounting opening 600 is disposed on the side of the test box body 500 .

[0038] In an optional embodiment, the assembly opening 600 of the test box body 500 is provided with a closed door.

[0039] The side of the test box body 500 is provided with an assembly port 600 , through which the battery is assembled into the test box body 500 , and a closed door is provided at the assembly port 600 , which closes the assembly port 600 to prevent the battery from escaping from the test box body 500 through the assembly port 600 .

[0042] In an optional embodiment, the elastic component 120 includes a plurality of tension springs 300 , one end of each tension spring 300 is connected to the upper support frame 200 , and the other end of each tension spring 300 is connected to the upper end surface of the test box body 500 .

[0043] In an optional embodiment, the elastic component 120 includes four tension springs 300 , and the four tension springs 300 are arranged in two rows and two columns.

[0044] The elastic component 120 includes a plurality of tension springs 300, generally including four tension springs 300, one end of the tension spring 300 is connected to the upper support frame 200, and the other end is connected to the test box body 500; due to the elasticity of the tension spring 300, when the test box body 500 is hit, the disorder of such vibration can be further amplified.

Since each vibration rod 700 is controlled individually, multiple vibration rods 700 are repeatedly installed on the test box body 500.

[0051] The test box body 500 of the vibration environment simulation device provided by the utility model is fixed on the upper support frame 200 through the elastic component 120, so that the test box body 500 is suspended in the air, and the multiple vibration rods 700 of the vibration component 110 can respectively impact the test box body 500, so that the test box body 500 vibrates disorderly, even if the battery is subjected to disorderly vibration. Since the test box body 500 is fixed by the elastic component 120, the elastic component 120 can further amplify such disorder of vibration, thereby simulating the disordered and irregular vibration environment of the battery in actual use.
