The application relates to the battery technical field and discloses a battery pack and an electric device, which comprise a box body, a cover body and a battery monomer assembly. The box body comprises a side plate and a containing cavity with an opening surrounded by the side plate; a glue groove is arranged on the side plate, a glue layer is arranged in the glue groove, a ventilation hole is arranged on the outer wall of the side plate, and the ventilation hole is communicated between the glue groove and the outside of the box body. The cover body is arranged on one side of the opening of the box body, the cover body seals the opening and is bonded with the glue layer in the glue groove. After the battery monomer assembly is arranged in the containing cavity, glue is poured into the glue groove. Then, the cover body is arranged on one side of the opening of the box body, so that the cover body seals the opening and the glue groove, and thus, after the glue solidifies to form the glue layer, the cover body can be bonded with the box body through the glue layer. Since the ventilation hole is arranged on the outer wall of the box body and is communicated between the glue groove and the outside of the box body, air can enter the glue groove through the ventilation hole and contact the glue, so that the glue can absorb the water vapor in the air and quickly solidify, and the forming efficiency of the glue layer is improved.

The invention discloses a liquid cooling driving pump body investment casting process which comprises the following steps: firstly, according to the size and the shape of a pump body, manufacturing a mold with a cavity consistent with the pump body and a loose piece for forming a complex inner cavity structure of the pump body, then injecting wax, molding a wax mold in the mold cavity by adopting a one-time mold splitting molding process, according to the pump body complex inner cavity wax mold, loose pieces are mutually positioned, combined and formed, then wax injection mold splitting is carried out to obtain a wax body, the wax body is connected to a mold head through a pouring gate system to form a tree group, then shell making and dewaxing are carried out on the tree group to form a mold shell, and then roasting, smelting pouring and post-treatment are carried out on the mold shell to form a casting. And the casting is further machined through overhauling, heat treatment, shaping and finish machining, and finally the qualified pump body is obtained if the casting is detected to be correct. Through one-time mold splitting of the wax piece with the complex structure in the inner cavity of the pump body, the mold splitting efficiency is improved, the cost is reduced, meanwhile, the pump body casting is corrected by adopting a one-time composite sizing mold after being subjected to smelting pouring, orderly cooling solidification and heat treatment, and the leakage risk of the pump body casting is greatly reduced.

This invention belongs to the field of sheet metal processing technology, specifically relating to a flexible progressive forming method for large sheet metal parts based on multi-robot collaboration. The method includes the following steps: dividing the three-dimensional model of the target component into several sub-regions based on its geometric features, and determining the tool head and forming process parameters for each robot in each sub-region; performing trajectory planning and motion synchronization for each robot; performing dynamic collision detection based on the real-time position feedback of each robot, and optimizing the trajectory through coordinated planning of speed and trajectory; and dynamically adjusting the forming process parameters of each robot based on the real-time force feedback of each tool head using a force / position hybrid control algorithm.
