[0024] The following will be combined with a schematic diagram to describe the battery cell temperature test tool of the present invention in more detail, wherein the preferred embodiment of the present invention is shown. It should be understood that those skilled in the art can modify the present invention described herein and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0025] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a battery cell temperature testing tool, including a support seat 1, a fixed longitudinal plate 2 and a clamping frame 3.

[0027] Specifically, the support seat 1 is used to fix and support the fixed longitudinal plate, the clamping frame and the battery cells.

[0028] The fixed longitudinal plate 2 is fixedly arranged at the end of the support seat 1, and a detection window 5 is arranged on the fixed longitudinal plate 2, and a plurality of first middle frames 9 are arranged on the detection window 5 at equal intervals, and a clamping groove 4 matching the battery cell is arranged on the periphery of the detection window 5.

[0029] The clamping frame 3 is arranged outside the clamping groove 4 , and the clamping frame 3 is detachably arranged on the side surface of the fixed longitudinal plate 2 , and a plurality of second middle frames 13 corresponding to the first middle frames 9 are arranged at equal intervals on the clamping frame 3 .

[0030] In this embodiment, when the battery cells need to be loaded, the support base 1 and the fixed longitudinal plate 2 are turned over and supported on the ground. At this time, the opening of the clamping groove 4 is in an inclined upward direction (such as Figure 3 As shown in the figure, it is convenient to put the battery cell into the clamping groove 4, and use the clamping frame 3 to fix the battery cell. After the battery cell is loaded, the tooling is moved to the light source of the stringer. After the battery cell absorbs the heat of the light source of the stringer, its surface temperature changes. At this time, the temperature size and uniformity can be tested by the infrared thermal imaging detector.

[0031] Among them, the infrared thermal imaging detector is a detection device that detects infrared heat through non-contact, converts it into a thermal image and temperature value, and then displays it on the display, and can calculate the temperature value. The infrared thermal imaging detector can accurately quantify the detected heat, and can accurately identify and strictly analyze the fault area of ​​heating.

[0032] When it is necessary to disassemble the battery cell, the support base 1 and the fixed longitudinal plate 2 are turned over and supported on the ground, the clamping frame 3 is opened, and the battery cell is located in the clamping groove 4. Since the edge of the clamping groove 4 has a certain limiting effect on the battery cell, the battery cell is stably located in the clamping groove 4. When it is necessary to take the battery cell out of the clamping groove, it is only necessary to lift the battery cell from the clamping groove 4 from the side of the detection window 5.

[0033] In order to facilitate placing the battery cell in the clamping groove 4, the outer edge of the clamping groove 4 has a chamfered structure. The inclined surface brought by the chamfered structure can guide the battery cell into the clamping, thereby facilitating placing the battery cell in the clamping groove 4.

[0034] In addition, in order to reduce the weight of the entire test fixture, a hollow hole 6 is provided on the fixed longitudinal plate 2 , and the hollow hole 6 is located outside the clamping groove 4 .

[0035] It should be noted that there is a predetermined gap between the first middle frame 9 and the second middle frame 13, and the predetermined gap is used to fix the edges of two adjacent battery cells. The predetermined gap is consistent with the thickness of the battery cell. When multiple battery cells are placed in the clamping groove 4, the edges of the two adjacent battery cells are surrounded and fixed by the first middle frame 9 and the second middle frame 13, which can effectively reduce the phenomenon of battery cell breakage and hidden cracks during temperature detection.

[0036] Furthermore, a reinforcing rib 7 is fixedly provided between the fixed longitudinal plate 2 and the support seat 1 , and the reinforcing rib 7 is located at the end portion at the angle between the fixed longitudinal plate 2 and the support seat 1 .

[0037] Specifically, two reinforcing ribs 7 are symmetrically arranged, and the middle of the reinforcing ribs 7 is hollowed out. The arrangement of the reinforcing ribs 7 can improve the reliability of the connection between the support seat 1 and the fixed longitudinal plate 2. In addition, the hollowing out of the middle of the reinforcing ribs 7 can reduce the weight of the entire test tooling.

[0038] Furthermore, a plurality of fastening holes are provided at the edge of the clamping frame 3 , and a fastening knob 8 is provided through the fastening hole, and the fastening knob 8 is threadedly connected to the fixed longitudinal plate 2 .

[0039] Specifically, when the battery cell needs to be installed, after placing the battery cell in the clamping groove 4, the clamping frame 3 is attached to the fixed longitudinal plate so that the first middle frame 9 corresponds to the second middle frame 13, and finally the fastening knob 8 is inserted into the fastening hole and tightened.

[0040] When the battery cell needs to be disassembled, the tightening knob is rotated to separate the tightening knob 8 from the fixed longitudinal plate 2, and finally the clamping frame 3 is removed from the fixed longitudinal plate 2. At this time, the restriction of the clamping frame 3 on the battery cell is released, and the battery cell can be taken out of the clamping frame.

[0041] It should be noted that the tightening knobs 8 are evenly distributed around the periphery of the clamping frame 4 , which can reduce deformation of the clamping frame 4 caused by uneven force.

[0042] Furthermore, a counterweight block 10 is disposed on the upper surface of the support base 1 , and the counterweight block 10 is located at an end of the support base 1 away from the fixed longitudinal plate 2 .

[0043] Specifically, a fixing groove 11 is provided on the upper surface of the support seat 1, and the counterweight block 10 is located in the fixing groove 11. After the support seat 1 is placed, the counterweight block 10 is placed in the fixing groove 11, so that the center of gravity of the test fixture is offset to the side of the counterweight block 10, thereby preventing the fixed longitudinal plate 2 from tilting and tipping.

[0044] In order to facilitate the taking and placing of the counterweight 10, a carrying handle 12 is provided on the counterweight 10. When the counterweight 10 is moved, the carrying operation of the counterweight 10 can be performed only by the carrying handle 12.

[0045] Compared with the prior art, the utility model has at least the following beneficial effects:

[0046] The utility model can realize the rapid disassembly and assembly of the battery cell by placing the battery cell in the clamping groove and disassembling and assembling the clamping frame. In addition, the cooperation between the detection window and the clamping frame can protect the edge of the battery cell, thus overcoming the problem of battery cell breakage and hidden cracks during the test, and has the characteristics of simple structure and convenient operation.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
