DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 8The utility model proposes a probe installation module 200 for installation on a battery test needle bed 100. The probe installation module 200 includes a fixing component 300, a positioning bar 400 and a probe component 500. The fixing component 300 is provided with a plurality of first screw holes 310; the positioning bar 400 is provided with a plurality of second screw holes 410; the probe component 500 includes a probe 510 and a mounting block 520, and the mounting block 520 is connected to the outer periphery of the probe 510; the mounting block 520 is provided with a barb 530, and the positioning bar 400 is provided with a barb groove 420. When the fixing component 300 and the positioning bar 400 are spliced ​​to limit the barb 530 in the barb groove 420, the first screw hole 310 and the second screw hole 410 are spliced ​​one-to-one and the probe 510 is fixed by screwing.

[0035] Specifically, the first screw hole 310 and the second screw hole 410 can be set to have the same diameter, so as to facilitate the alignment and splicing of the first screw hole 310 and the second screw hole 410. During the assembly process, the fixing assembly 300 is directly fixed on the battery test needle bed 100, and the probe assembly 500 is a whole, and the probe 510 is fixed on the needle bed 100 by the hook 530 connected to the mounting block 520 on the probe 510. The assembly process of the probe installation module 200 of the utility model for assembling the probe assembly 500 to the battery test needle bed 100 is as follows: the fixing assembly 300 is fixed, first the positioning bar 400 is aligned and spliced ​​onto the fixing assembly 300, the first screw hole 310 and the second screw hole 410 are spliced ​​through, and the first screw hole 310 and the second screw hole 410 are screwed through with a screw, and at the same time, the screws are not tightened so that a certain distance is maintained between the positioning bar 400 and the fixing assembly 300, and space is reserved for the hook groove 420 for the hook 530 of the mounting block 520 on the probe 510 to be buckled and installed. After the hook 530 of the probe 510 is positioned, the positioning block 540 is further pushed in, and the screws are tightened again to further strengthen the connection effect, thereby ensuring the installation stability of the probe 510. With such a configuration, the positioning bar 400 is used to press the barb 530 on the probe assembly 500 into the barb groove 420 of the fixing assembly 300, so that the probe assembly 500 can be installed in the needle bed 100. Compared with the traditional method of installing each probe 510 one by one using one screw, the utility model only needs a few screws to tighten the positioning bar 400 to install multiple probes 510, which not only ensures the assembly stability, but also simplifies the assembly process and improves the assembly efficiency.

[0036] See also Figures 4 to 7Furthermore, the positioning bar 400 is also provided with a plurality of positioning grooves 430, each positioning groove 430 is connected to the hook groove 420, and each hook 530 is provided with a positioning block 540, and the positioning block 540 can extend into the positioning groove 430. In this way, during the assembly process, after the space between the positioning bar 400 and the fixing assembly 300 is reserved, the positioning block 540 on the hook 530 of the probe 510 first extends into the positioning groove 430 to play a positioning and limiting role, and then gradually advances so that the hook 530 is completely adapted to the hook groove 420, and finally the first screw hole 310 and the second screw hole 410 are screwed together to connect and fix the positioning bar 400 and the fixing assembly 300. The positioning block 540 first positions the positioning bar 400 to facilitate the positioning of the probe 510 and improve the installation stability effect.

[0037] See also Figure 4 Furthermore, the positioning block 540 is connected to the middle position of the barb 530. With such a configuration, the positioning block 540 is evenly stressed after being inserted into the positioning groove 430, the barb 530 is adapted to the shape of the barb groove 420, and the barbs 530 are supported in the barb groove 420 on both sides of the positioning block 540, thereby preventing the probe 510 from shaking and maintaining the stability of the probe 510.

[0038] See also Figure 1 and Figure 4 Furthermore, the height of the barb 530 protruding from the mounting block 520 gradually increases from the direction close to the probe 510 to the direction away from the probe 510. At the same time, the shape of the barb groove 420 is adapted to the shape of the barb 530 to ensure the structural installation stability of the two.

[0039] See also Figures 1 to 3 Furthermore, there are multiple positioning bars 400, and the multiple positioning bars 400 are sequentially spliced ​​and press the hook 530 on the fixing assembly 300 to fix the probe 510. Each positioning bar 400 is used to install multiple probes 510. By setting multiple positioning bars 400 to share the installation of multiple probes 510, the pressure of the positioning bars 400 on the probe 510 is ensured, and the stability of the installed probe 510 is ensured.

[0040] See also Figure 1 Furthermore, on each positioning bar 400, the number of the second screw holes 410 is less than the number of the positioning grooves 430. The number of screw holes only needs to ensure that the positioning bar 400 can be fixedly assembled to the fixing assembly 300, and the number of screw holes can be set to be less than the number of probes 510 installed on one positioning bar 400, so that the installation efficiency can be improved.

[0041] See also Figure 3Furthermore, the plurality of first screw holes 310 are arranged at equal intervals along the length direction of the fixing assembly 300. The plurality of first screw holes 310 are arranged on the same straight line, and the first screw holes 310 are arranged on the central axis of the length direction of the fixing assembly 300.

[0042] See also Figure 6 to Figure 7 Furthermore, the plurality of second screw holes 410 are arranged at equal intervals along the length direction of the positioning bar 400. The plurality of first screw holes 310 are arranged on the same straight line, and the first screw holes 310 are arranged on the central axis of the length direction of the fixing assembly 300.

[0043] The probe 510 can be of various types, such as a voltage probe 510 or a temperature probe 510. Furthermore, the probe 510 is a temperature probe 510. The present embodiment uses a temperature probe 510 to detect the temperature of the battery cell during the process of forming a capacity. Of course, the above-mentioned hook 530 structure can also be set on other types of probes 510, such as a current probe 510, a voltage probe 510, etc.

[0044] See also Figure 8 The utility model also proposes a battery test needle bed 100, which includes a needle bed 100 and a probe installation module 200. The probe installation module 200 is installed on the needle bed 100. The specific structure of the probe installation module 200 refers to the above embodiment.
