Fig. 1 shows an embodiment of the present invention for disassembling the auxiliary workpiece of the battery module, which includes a plastic block 1 made of epoxy resin, and the plastic block is a unitary structure. The bottom surface 1a of the plastic block 1 is integrally formed with a plurality of arc-shaped grooves 101 extending straight from front to back, and the arc-shaped grooves 101 are arranged in parallel with each other, so that a rib 102 extending straight from front to back is formed between any two adjacent arc-shaped grooves 101. The front end surface 1b of the plastic block 1 is a vertical surface. The rear end surface 1c of the plastic block 1 is provided with a knocking surface 1c-1 which is obliquely arranged and has a planar structure, and the top edge of the knocking surface 1c-1 is closer to the front end surface 1b than the bottom edge of the knocking surface 1c-1, namely the top edge of the knocking surface is arranged more forwards than the bottom edge of the knocking surface.

Fig. 2 is a demonstration diagram of disassembling a battery module by using the auxiliary workpiece, and the same as the conventional battery module is that the battery module 2 in fig. 2 also includes a plurality of battery cells 201 and a plurality of battery clamps for supporting the battery cells, the battery clamps are sequentially arranged from front to back at intervals, a plurality of battery cells 201 arranged in a matrix are uniformly arranged between any two adjacent battery clamps, and the front and back ends of each battery cell 201 are respectively inserted into the battery insertion holes of the two adjacent battery clamps. The battery cells 201 arranged in a matrix in the same layer and the battery holders at the ends thereof constitute a small battery module. If a certain battery module has a fault and the battery module needs to be disassembled, a worker can arrange the plastic block 1 at the side part of the battery module, and ensure that the arc surface-shaped groove 101 at the bottom surface of the plastic block is attached to the surfaces of the battery monomers 201 and the convex rib 102 just extends into a gap between two adjacent battery monomers 201. The knocking surface 1c-1 of the plastic block 1 is knocked forwards by adopting a hammer or other knocking components, and because the knocking surface 1c-1 is an inclined surface with a front inclined surface, knocking force acting on the knocking surface 1c-1 can be divided into a forward component and a downward component, the forward component promotes the plastic block 1 to move forwards, and the downward component enables the plastic block 1 to downwards press the battery module so as to keep close to the battery module. When plastic block 1 moves forward, its front end face 1b abuts against the side of the corresponding battery holder 202, and pulls out the battery holder 202 from the end of the battery under the action of the knocking force; then, the plastic block 1 is arranged at the side of the battery module adjacent to the aforementioned failed battery module in the same manner, and the plastic block 1 is knocked, and finally the failed battery module is detached from the battery module.

In order to save material and reduce the size of the plastic block 1, the top surface 1d of the plastic block 1 is also provided as a plane that is obliquely arranged, and the front side of the top surface 1d is closer to the bottom surface 1a than the rear side of the upper end surface 1 d. Therefore, the knocking surface 1c-1 can be ensured to have a large enough area so as to facilitate the operation of arbitrarily knocking the plastic block.

In this embodiment, the rear end surface 1c of the plastic block 1 is formed by a lower vertical surface and an upper inclined surface, and the striking surface 1c-1 is the inclined surface.

In addition, in the embodiment, a plurality of lightening holes 103 are formed on the plastic block 1, so that the material and the dead weight of the plastic block are further reduced, and the plastic block is convenient to carry.

In addition, the bottom surface 1a of the plastic block 1 is also provided with an avoiding groove 104, and when the battery module is disassembled, the avoiding groove 104 can avoid the voltage collecting piece in the battery module to prevent the voltage collecting piece from being damaged.

The left end face and the right end face of the plastic block 1 are both vertical planes.
