[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0024] like Figure 1-5 As shown, the utility model provides a battery module testing device, including two testing devices 1 and a supporting plate 100, one end of the supporting plate 100 is fixedly connected to an external plate 1001, and two reinforcement blocks 6 are fixedly installed on the top of the external plate 1001. A protective plate 2 is fixedly installed at one end of each of the two testing devices 1, and a mounting plate 5 is fixedly installed at one end of one of the testing devices 1, and one end of the mounting plate 5 is in contact with the two reinforcement blocks 6. A hinge 3 is provided between the two testing devices 1, and both are arranged on the top of the supporting plate 100, and a moving mechanism 4 is provided at one end of the mounting plate 5. The moving mechanism 4 includes a motor 401, a screw 402 and a slider 403. The motor 401 drives the screw 402 to rotate. When the screw 402 rotates, the test device 1 is driven to move horizontally on the top of the supporting plate 100 through the slider 403 and the mounting plate 5.

[0025] When testing multiple battery modules in different orientations at the same time, the operator can rotate one of the test devices 1 through the hinge 3 so that the rear shells of the two test devices 1 can be arranged relative to each other, thereby making the output ends of the two test devices 1 in opposite directions, making it easier to test multiple battery modules in different orientations at the same time, effectively expanding the scope of application of the equipment, improving applicability and work efficiency;

[0026] When the battery module is far away from the test device 1 and the test line is not long enough, the staff starts the motor 401. When the output end of the motor 401 rotates, it first drives the screw 402 to rotate. When the screw 402 rotates, it engages with the slider 403 thread, so that the slider 403 can slide horizontally. When the slider 403 moves, it drives the mounting plate 5 to move. When the mounting plate 5 moves, it drives the two test devices 1 to move horizontally, thereby adjusting the distance between the two test devices 1 and the battery module. Under the premise of not changing the test line, the test device 1 can test battery modules in different positions, further improving the applicability of the equipment, and there is no need to change the test line, effectively reducing the operation time, and improving work efficiency and applicability.

[0027] The testing device 1 is a prior art and will not be explained here.

[0028] like Figure 2 As shown, in one embodiment, the moving mechanism 4 also includes a fixed block 404, which is fixedly mounted on one end of the supporting plate 100, the motor 401 is fixedly mounted on the top of the external plate 1001, one end of the screw 402 is fixedly connected to the output end of the motor 401, and the other end is rotatably connected to the fixed block 404, the slider 403 is threadedly sleeved on the screw 402, and one end is fixedly connected to the mounting plate 5.

[0029] The fixed block 404 is used to limit the slider 403. At the same time, the external plate 1001 is provided to prevent one of the test devices 1 from contacting the moving mechanism 4 during rotation, thereby expanding the distance between the structures and improving applicability.

[0030] like Figure 3 As shown, in one embodiment, a slide groove 1002 is opened at one end of the supporting plate 100, and the inner wall of the slide groove 1002 is fixedly connected to a guide rod 1006, the slider 403 slides with the slide groove 1002 and is slidably sleeved on the guide rod 1006, and a plurality of legs 1003 are fixedly installed on the bottom of the supporting plate 100, and anti-slip pads 1004 are fixedly installed on the bottom of the plurality of legs 1003, and a protective cover 1005 is slidably sleeved on the outer wall.

[0031] Several legs 1003 are used to support the supporting plate 100 and the testing device 1, increase the height of the equipment, and facilitate operation by staff. At the same time, the anti-slip pad 1004 can increase the friction between the equipment and the ground to prevent the equipment from shifting during use. The protective cover 1005 can protect the legs 1003 to prevent the legs 1003 from being easily damaged and affecting the normal use of the equipment, further improving the applicability and extending the service life of the equipment.

[0032] like Figure 4 As shown, in one embodiment, the output end of the test device 1 is provided with several socket one 101 and several socket two 102, and the specifications of socket one 101 and socket two 102 are different. A start switch 103 is provided at one end of the test device 1, and a warning light 104 is provided on the top.

[0033] By setting the socket 101 and the socket 2 102 of different specifications, different test lines can be selected when testing the battery module, thereby reducing limitations.

[0034] like Figure 1 and Figure 5 As shown, in one embodiment, a connecting wire 7 is provided on the inner wall of one of the sockets 102, and the connecting wire 7 is slidably fitted with the socket 102. One end of the connecting wire 7 is fixedly connected to a connecting plate 8 by a bolt 9, and one end of the connecting plate 8 is provided with two connecting holes 801.

[0035] If several connection holes 801 used for testing are damaged, the staff can select another connection hole 801 to test again. By setting two connection holes 801, there are multiple options when testing the battery module, and there is no need to frequently replace the connection plate 8, thereby improving applicability.

[0036] The following is a detailed description of the working principle of the battery module testing device:

[0037] When the staff needs to test the battery module, they first insert the corresponding socket 101 and socket 2 102 according to the specifications of the connecting wire 7, and then fix the connecting plate 8 to the output end of the connecting wire 7 by means of the bolt 9. After the connecting plate 8 is installed, the connecting hole 801 on the connecting plate 8 is sleeved on the battery module, and then the test device 1 is started by the start switch 103 to test the battery module. After the battery module test is completed, if some of the connecting holes 801 used for the test are damaged, the staff can select another connecting hole 801 to test again. By providing two connecting holes 801, multiple options can be selected when testing the battery module, and there is no need to frequently replace the connecting plate 8, thereby improving applicability.

[0038] When testing multiple battery modules in different orientations at the same time, the operator can rotate one of the test devices 1 through the hinge 3 so that the rear shells of the two test devices 1 can be arranged relative to each other, thereby making the output ends of the two test devices 1 in opposite directions, making it easier to test multiple battery modules in different orientations at the same time, effectively expanding the scope of application of the equipment, improving applicability and work efficiency;

[0039] When the battery module is far away from the test device 1 and the length of the connecting line 7 is not enough, the staff starts the motor 401. When the output end of the motor 401 rotates, it first drives the screw 402 to rotate. When the screw 402 rotates, it cooperates with the slider 403 thread, so that the slider 403 can slide in the slide groove 1002 and on the guide rod 1006. When the slider 403 moves, it drives the mounting plate 5 to move. When the mounting plate 5 moves, it drives the two test devices 1 to move horizontally, thereby adjusting the distance between the two test devices 1 and the battery module, so that the connecting plate 8 can test the battery module again through the connecting hole 801 under the action of the connecting line 7. The test device 1 can test battery modules in different positions without replacing the connecting line 7, further improving the applicability of the equipment, and there is no need to replace the connecting line 7, effectively reducing the operation time, and improving work efficiency and applicability.

[0040] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of the present invention.
