Example one

As shown in fig. 1, the utility model discloses a battery box, including the open, inside hollow lower box 1 in top side and install the upper cover 2 of box 1 open end down, upper cover 2 and lower box 1 form one jointly and hold the cavity, should hold and install the battery package in the cavity. Lower box 1's open end integrated into one piece has lower connecting portion 3, and the bottom side edge integrated into one piece of upper cover 2 has upper connecting portion 4, and upper connecting portion 4 specifically is the mounting panel that the bottom side edge of upper cover 2 extends to the outside on the horizontal plane, and the downside of upper connecting portion 4 closely laminates with the side of going up of lower connecting portion 3, makes the inside formation of upper cover 2 and lower box 1 hold the chamber. An annular glue containing groove 5 is formed in the upper side face of the upper connecting portion 4, a sealing medium 6 is filled in the glue containing groove 5, and the sealing medium 6 is liquid sealant.

During assembly, firstly, the glue containing groove 5 is filled with liquid sealant, so that the liquid sealant flows in the glue containing groove 5 according to the characteristics of the liquid sealant, the glue containing groove 5 is filled with the liquid sealant, and then the lower side surface of the upper connecting part 4 is tightly attached to the upper side surface of the lower connecting part 3, so that the gap between the upper cover 2 and the lower box body 1 is filled with the liquid sealant in a matching manner, and the sealing effect is achieved. Compared with the mode of compressing the sealing gasket in the traditional process, the sealing effect is good, and the production efficiency can be well improved.

In another embodiment, the sealing medium 6 may also be a foam rubber, which has a better self-expansion performance, and is more convenient to compress and capable of improving the production efficiency compared with the conventional sealing gasket.

In this embodiment, the cross section of the glue accommodating groove 5 is an isosceles trapezoid structure with a large top and a small bottom. By adopting the structure, the sealing medium 6 is convenient to mount, and the contact area between the sealing medium 6 and the upper connecting part 4 can be increased, so that a better sealing effect is achieved.
