[0028] like Figure 1 and Figure 2 As shown, a welding protection fixture of a preferred embodiment of the utility model comprises a base 1, a protection base 2 and a fixing base 3, wherein the base 1 has a first direction X, a second direction Y and a third direction Z intersecting in pairs, wherein the first direction X is the width direction of the base 1, the second direction Y is the length direction of the base 1, and the third direction Z is the height direction of the base 1. Preferably, the first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs.
[0029] In the welding protection fixture of the preferred embodiment of the utility model, the base 1 is provided with at least one accommodating groove 11 facing the third direction Z, and the accommodating groove 11 has an opening penetrating the base 1 in the third direction Z. The accommodating groove 11 can be set as a rectangular groove or a circular groove according to the shape of the protection seat 2, and is not specifically limited here; further, a plurality of accommodating grooves 11 can be set on the base 1, and the plurality of accommodating grooves 11 are evenly arranged in the second direction Y of the base 1, and each accommodating groove 11 can accommodate a protection seat 2.
[0030] In the welding protection fixture of the preferred embodiment of the utility model, the shape and size of the protection seat 2 match the accommodating groove 11, one end of the protection seat 2 is located in the accommodating groove 11, and the other end of the accommodating groove 11 extends along the third direction Z and is penetrated through the bottom opening of the accommodating groove 11 to the base 1, and the end of the protection seat 2 extending out of the base 1 is used to abut the welding adapter; a fixed seat 3 is also provided in the accommodating groove 11, and the fixed seat 3 is provided on one side of the protection seat 2 along the third direction Z, so that the protection seat 2 is located between the fixed seat 3 and the base 1, and the fixed seat 3 is fixedly connected to the base 1 to confine part of the protection seat 2 in the accommodating groove 11, and a gap is left between the fixed seat 3 and the protection seat 2, and a deformable buffer element 31 is provided in the gap, and the buffer element 31 extends along the third direction Z.

The second fixing hole 14 is arranged close to the side wall of the receiving groove 11 to prevent interference with the protective seat 2 area in the middle of the receiving groove 11. A fixing member 33 is arranged in the first fixing hole 32 to fix the fixing seat 3 to the base 1. The fixing member 33 is sequentially inserted into the first fixing hole 32 and the second fixing hole 14 during installation, and the base 1 and the fixing seat 3 are fixed by the fixing member 33. Specifically, the first fixing hole 32 and the second fixing hole 14 are arranged as screw holes, and the fixing member 33 is arranged as a stud, so that the base 1 and the fixing seat 3 are firmly fixed and easy to disassemble and assemble.
[0038] In some embodiments of the utility model, a plurality of first fixing holes 32 are evenly arranged at the four corners of the fixing seat 3, and a plurality of second fixing holes 14 corresponding to the plurality of first fixing holes 32 are also arranged in the accommodating groove 11, and a fixing member 33 is inserted in each group of the first fixing holes 32 and the second fixing holes 14.

This is beneficial for the welding protection fixture to cope with the protection of adapters of different thicknesses, and prevents the occurrence of compression and tilting when the adapter is too thick, making it difficult to fully and evenly apply force to the top cover and the adapter, and also prevents the possibility that the fixture part is not in place when the adapter is too thin, causing welding slag to splash and damage the battery cell.
