[0020] See also Figure 1-3 According to an embodiment of the present invention, a fixture for testing new energy vehicle batteries includes an insulating base plate 1, which is located at the bottom of the entire device. A mounting seat 2 is fixedly installed on the insulating base plate 1, a driving mechanism 3 is installed on the mounting seat 2, and a clamping mechanism 4 is installed on the driving mechanism 3.

[0021] Among them, the insulating base plate 1 can isolate the electrical connection between the fixture and the ground to ensure the correctness of the test, and the mounting seat 2 is connected to the mounting drive mechanism 3 and the clamping mechanism 4.

[0022] In this embodiment, the driving mechanism 3 includes a first side plate 5 fixedly mounted at both ends of the mounting seat 2, a screw rod 6 passing through the middle of the first side plate 5 and rotatably mounted through a bearing, a limiting rod 7 is fixedly mounted between the horizontal sides of the first side plate 5, the screw rod 6 passes through and is threadedly connected to a moving block 8, and through holes are provided at both ends of the moving block 8 and are slidably connected to the limiting rod 7.

[0023] Among them, the limiting rod 7 ensures that the moving block 8 moves in the horizontal direction without shaking, and the screw rod 6 drives the moving block 8 to move horizontally.

[0024] In this embodiment, one end of the screw rod 6 is fixedly connected to a rotating rod 9, and a driven wheel 10 is fixedly installed on the end of the rotating rod 9. The driven wheel 10 engages with the driving wheel 11, and the driving wheel 11 is installed on the output end of the motor 12 through a rotating shaft.

[0025] The motor 12 drives the driving wheel 11 to rotate via the rotating shaft, the driving wheel 11 drives the driven wheel 10 to rotate, the driven wheel 10 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the screw rod 6 to rotate.

[0026] In this embodiment, the clamping mechanism 4 includes a second side plate 13 fixedly mounted on the top of the first side plate 5, a third side plate 14 fixedly mounted on the top of the moving block 8, and a sleeve 15 is passed through and fixedly mounted in the middle of the second side plate 13 and the third side plate 14, and a conductive sliding rod 16 is slidably connected in the sleeve 15.

[0027] The sleeve 15 facilitates the horizontal sliding of the conductive sliding rod 16 .

[0028] In this embodiment, a conductive clamp 17 is fixedly installed on one end of the conductive slide rod 16, and a conductive block 18 is fixedly installed on the other end of the conductive slide rod 16. A connecting groove 19 is opened on the conductive block 18, and the connecting groove 19 is connected to the test equipment wire. A spring 20 is fixedly connected between the conductive clamp 17 and the side wall of the sleeve 15 and wraps the conductive slide rod 16.

[0029] Among them, the conductive clamp 17 is used to clamp the two poles of the battery, the connection groove 19 opened on the conductive block 18 is convenient for winding the wires connecting the test equipment, and the function of the spring 20 is to ensure the reset of the conductive clamp 17 after the battery is released, and at the same time it can also avoid damage to the two poles of the battery caused by excessive clamping force.
