Description

Technical Field

[0001] The utility model belongs to the technical field of battery packs, and in particular relates to a soldering tin tank for a battery core bracket of a battery pack. Background Art

[0002] In the battery pack, the connecting piece of the battery cell and the sampling line led out from the control board are generally connected by soldering. During the soldering process, excess solder will appear and flow out, which can easily damage the battery cell. In addition, the flowed solder can easily enter the gap between the connecting piece and the battery cell bracket, causing a short circuit. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a soldering groove for a cell holder of a battery pack. By arranging a soldering groove in the positioning groove of the connecting piece, it is possible to collect excess and outflowing solder during the soldering process, thereby preventing the overflowing solder from damaging the cell.

[0004] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a battery cell bracket solder groove of a battery pack, including a battery cell bracket, on which a solder groove is provided. The solder groove is arranged corresponding to the welding connection position between the sampling line and the connecting piece of the battery pack to accommodate the solder overflowing during the soldering process.

[0005] Furthermore, the battery cell bracket has a connecting piece positioning groove, and the solder groove is located in the connecting piece positioning groove.

[0006] Furthermore, the solder groove is located at the bottom of the connection piece positioning groove.

[0007] Furthermore, the solder groove is located at the edge of the groove wall of the connecting piece positioning groove. When the connecting piece is installed in the connecting piece positioning groove, the solder groove corresponds to the solder point area of ​​the connecting piece.

[0008] Furthermore, the cell support is provided with a wire harness slot extending from the control board of the battery pack to the connecting piece, and the end of the wire harness slot extends into the positioning slot of the connecting piece to conduct the soldering groove.

[0009] Furthermore, the terminal end of the wire harness trough extends into the solder bath.

[0010] Furthermore, the bottom of the solder bath is a planar structure.

[0011] Furthermore, the solder bath has a trapezoidal structure, and the long side of the solder bath of the trapezoidal structure is located on the side of the wire harness trough.

[0012] Beneficial effects: The utility model sets a solder groove in the connecting piece positioning groove. The solder groove can accommodate excess and outflowing solder during the soldering process, thereby preventing the overflowing solder from damaging the battery cell and improving the assembly quality and safety of the battery pack. In addition, after the outflowing solder is accommodated by the solder groove, it can be prevented from entering the gap between the connecting piece and the battery cell bracket and becoming debris to cause a short circuit, further improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is an enlarged structural diagram of the area where one of the solder grooves of the battery cell holder is located in a three-dimensional perspective;

[0014] Figure 2 This is an enlarged structural view of the area where one of the solder grooves of the battery pack's cell holder is located from the main viewing angle. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, a battery pack cell holder solder groove includes a cell holder 1. The cell holder 1 is provided with a solder groove 2. The solder groove 2 is arranged corresponding to the welding connection position between the sampling line and the connecting piece of the battery pack to receive solder that overflows during the soldering process. The cell holder 1 has a connecting piece positioning groove 3, and the solder groove 2 is located within the connecting piece positioning groove 3. The solder groove 2 is located at the groove wall edge of the connecting piece positioning groove 3. When the connecting piece is installed in the connecting piece positioning groove 3, the solder groove 2 corresponds to the solder point area of ​​the connecting piece. By providing the solder groove 2 within the connecting piece positioning groove 3, the solder groove 2 can receive excess, outflowing solder during the soldering process, thereby preventing the overflowing solder from damaging the battery cell and improving the assembly quality and safety of the battery pack. In addition, after the outflowing solder is received by the solder groove 2, it is prevented from entering the gap between the connecting piece and the cell holder 1 and becoming debris and causing a short circuit, further improving safety.

[0017] In order to better and more easily accommodate the solder, in the present invention, the solder groove 2 is located at the bottom of the connecting piece positioning groove 3.

[0018] like Figure 1 As shown, the cell bracket 1 is provided with a wire harness trough 4 extending from the control board of the battery pack to the connecting piece. The wire harness trough 4 is used to harness the sampling line connecting the control board to the connecting piece. Due to the presence of the solder groove 2 in the connecting piece positioning groove 3, in order to ensure the harness effect of the sampling line, in this practice, the end of the wire harness trough 4 extends into the connecting piece positioning groove 3 to conduct the solder groove 2. More specifically, the end of the wire harness trough 4 extends into the solder groove 2.

[0019] like Figure 1 As shown, the bottom of the solder tank 2 is a flat structure, which ensures that the solder contained is evenly distributed in the tank.

[0020] like Figure 1 or Figure 2 As shown, the solder tank 2 has a trapezoidal structure, and the long side of the trapezoidal solder tank 2 is located on the side of the wire harness slot 4, ensuring that the width of the solidified solder block structure is first large and then small in the direction of internal extension from the solder point to the connecting piece positioning slot 3, ensuring the stability of the solder block fixed in the solder tank 2.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
