[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] The box 10 of an embodiment of the present utility model includes a base plate 1, a partition plate 2, a cover plate 3 and multiple enclosures 4, a plurality of enclosures 4 are provided on the circumference of the cover plate 3, and one of the enclosures 4 is rotatably connected to the cover plate 3, the base plate 1 is connected to one end of the plurality of enclosures 4 away from the cover plate 3, and a plurality of enclosures 4 are provided on the circumference of the base plate 1, and the plurality of enclosures 4 are connected end to end to form a cavity between the enclosures 4, the cover plate 3 and the base plate 1, the partition plate 2 is detachably connected to the enclosure 4, the partition plate 2 is provided in the cavity, and the partition plate 2 divides the cavity into a wire harness collection cavity 5 and a test tool installation cavity 6.

[0032] The box 10 of the embodiment of the present invention facilitates installation and carrying of the test tool 20 for testing the battery pack, thereby improving the convenience of the battery pack test.

[0033] Specifically, if Figures 1 to 4 As shown, the lower end of the cover plate 3 is pivotally connected to any of the enclosure panels 4 circumferentially of the cover plate 3 , for example, by a hinge. The cover plate 3 rotates relative to the enclosure panel 4 to open or close the wiring harness collection chamber 5 . Opening the wiring harness collection chamber 5 facilitates the arrangement and collection of the wiring harness after testing within the wiring harness collection chamber 5 . After collection is complete, the cover plate 3 is flipped over to close the wiring harness collection chamber 5 .

[0034] The partition 2 is arranged between the cover plate 3 and the base plate 1 to separate the cavity into the wire harness collecting cavity 5 and the test tool installation cavity 6. At the same time, it facilitates the installation of the test tool 20 in the test tool installation cavity 6, and facilitates the collection of the wire harness in the wire harness collecting cavity 5 without the need to carry the test tool 20, the power supply 30, the wire harness and the wire harness collection device at the same time.

[0035] The enclosure 4, partition 2, and cover 3 are all made of insulating materials, minimizing the risk of electric shock. The box 10 is highly portable, significantly reducing safety risks and lowering transportation costs. After repairs, the battery pack performance can be immediately tested at the original repair site, improving repair efficiency. By changing the shape of the box 10, it can accommodate more electrical performance test fixtures 20.

[0036] In some embodiments, the distance between the partition plate 2 and the cover plate 3 is less than or equal to the distance between the partition plate 2 and the bottom plate 1 .

[0037] Specifically, if Figures 1 to 4 As shown, the enclosure 4 extends in the vertical direction, and the partition 2 divides the cavity into two chambers in the vertical direction: an upper wiring harness collection chamber 5 and a lower test fixture installation chamber 6. Furthermore, the vertical spacing between the partition 2 and the cover plate 3 is set to be less than or equal to the spacing between the partition 2 and the base plate 1. In other words, the vertical dimension of the wiring harness collection chamber 5 is less than or equal to the vertical dimension of the test fixture installation chamber 6. This provides sufficient installation space for the test fixture 20, facilitating the installation of different types of test fixtures 20 and improving the applicability of the box 10.

[0038] Furthermore, the partition 2 is detachably connected to the enclosure 4. For example, the partition 2 and the enclosure 4 are connected by threads, and countersunk holes are arranged in a matrix and spaced apart in the vertical direction on the circumference of the enclosure 4, so that bolts can pass through the countersunk holes to fix the partition 2 to different positions of the enclosure 4 in the vertical direction. Alternatively, threaded rods are provided at the four corners of the partition 2, and the lower ends of the threaded rods are in contact with the bottom plate 1, or the threaded rods are rotatably connected to the bottom plate 1, and the threaded rods are also threadedly connected to the partition 2, so that the position of the partition 2 in the vertical direction can be easily changed by rotating the threaded rods. Finally, the partition 2 is fixed in the cavity by bolts passing through the countersunk holes.

[0039] In some embodiments, the cover plate 3 is provided with a first opening 31, and the first opening 31 is provided at the end of the cover plate 3 away from the pivotal connection between the cover plate 3 and the enclosure 4, and the partition 2 is provided with a second opening 21, and the first opening 31 and the second opening 21 are staggered in the height direction of the partition 2.

[0040] Specifically, if Figures 1 to 4 As shown, the first opening 31 on the cover plate 3 facilitates the wire harness in the wire harness collecting cavity 5 to extend out of the box 10 so as to be connected to the external component to be tested to test the external component.

[0041] The second hole facilitates the wiring harness in the wiring harness collecting cavity 5 to extend into the test fixture installation cavity 6 and connect to the test fixture 20.

[0042] At the same time, in order to collect more wire harnesses, the positions of the first port 31 and the second port 21 in the vertical direction are staggered. Since the wire harness has a certain elasticity and hardness, the first port 31 and the second port 21 are coaxially arranged in the direction of gravity, or the first port 31 and the second port 21 are coaxially arranged in the vertical direction. The wire harnesses entering and exiting the first port 31 or the second port 21 will affect the wire harnesses in the wire harness collection cavity 5, thereby avoiding affecting the length of the collected wire harnesses.

[0043] In some embodiments, the thickness of the enclosure 4 and the bottom plate 1 are both 3 mm to 20 mm.

[0044] By setting the thickness of the enclosure 4 and the bottom plate 1, it is avoided that the thickness of the enclosure 4 and the bottom plate 1 is too small, which leads to low structural strength, and the stability and safety of the box 10 during use are improved.

[0045] At the same time, by setting the thickness of the enclosure 4 and the bottom plate 1, it is avoided that the insulation performance is reduced due to the thickness of the enclosure 4 and the bottom plate 1 being too small, thereby improving the stability and safety of the box 10 during use.

[0046] In some embodiments, the box 10 further includes a first handle 7 , which is disposed at one end of the cover 3 adjacent to the first opening 31 .

[0047] Specifically, if Figures 1 to 4 As shown, the first handle 7 is arranged at one end away from the pivotal connection between the cover plate 3 and the enclosure plate 4, so as to facilitate flipping the cover plate 3 to collect the wiring harness.

[0048] Furthermore, there are multiple first handles 7 , and the multiple first handles 7 are arranged relatively to each other in the extension direction of the partition 2 .

[0049] In some embodiments, the box 10 further includes a second handle, and there are multiple second handles, with at least one second handle being provided on any two non-adjacent panels 4 .

[0050] That is, the second handle is provided on the enclosure 4, and a plurality of second handles are provided on any two non-adjacent enclosures 4 so that personnel can pick up the box 10 through the second handles, thereby facilitating the overall movement of the box 10.

[0051] In some embodiments, the bottom of the bottom plate 1 is provided with anti-skid grooves. The bottom end of the bottom plate 1 is provided with anti-skid grooves to prevent the box 10 from moving relative to the ground when in use, thereby improving the stability of the box 10 in use.

[0052] Alternatively, an anti-skid pad is provided at the bottom of the base plate 1. The anti-skid pad is made of insulating material to avoid electrical connection between the base plate 1 and the ground.

[0053] The test device of the present embodiment includes a test fixture 20, a power supply 30, a wiring harness, and a box 10. Box 10 is any of the boxes 10 described above. Test fixture 20 and power supply 30 are detachably mounted within test fixture mounting cavity 6. Power supply 30 is connected to test fixture 20 to provide power to test fixture 20. One end of the wiring harness is detachably connected to test fixture 20 through partition 2, and the other end of the wiring harness is detachably mounted through cover 3 to extend out of box 10. The wiring harness is at least partially located within wiring harness collection cavity 5. Power supply 30 can be an existing battery, energy storage assembly, or energy storage device.

[0054] Specifically, if Figures 1 to 4 As shown, the wire harness collecting cavity 5 in the box 10 is used to collect the wire harness, and the test tool installation cavity 6 in the box 10 is suitable for installing the test tool 20. One end of the wire harness in the wire harness collecting cavity 5 passes through the first port 31 and is connected to the external component to be tested, and the other end of the wire harness in the wire harness collecting cavity 5 passes through the second port 21 and is connected to the test tool 20.

[0055] The testing device of the embodiment of the present invention facilitates the installation and carrying of the testing tool 20 for testing the battery pack, thereby improving the convenience of the battery pack test.
