Description

Battery connection module

The present invention relates to a battery connection module, in particular to a battery connection module for modular connection of battery packs.

Chinese Invention Patent Publication No. CN104137297A (corresponding to US Patent No. US9,431,811) discloses an insulating cover for covering the housing of a bus bar module. The housing accommodates the bus bar. The insulating cover includes a central cover and two side covers in an integrated structure. The central cover covers the voltage detection wire accommodating part of the housing. The two side covers cover the bus bar accommodating part of the housing. The two side covers 122 are respectively arranged at opposite sides of the central cover by using hinges between the central cover and the two side covers. In a state where the two side covers are respectively folded onto the central cover through a hinge, one side cover and the other side cover of the two side covers are locked to each other by a locking mechanism. However, the central cover and the two side covers are constructed into an integrated structure, and the hinge between them is an integrated plastic hinge structure. When the two side covers are opened, the plastic hinges need to be bent and deformed, which results in larger Reverse cover force, so when the two side covers are respectively folded on the central cover, two locking mechanisms must be used to lock each other to fix the two side covers. Therefore, when the two side covers are in the open position, additional operation of the locks is required, which causes troubles in operation. Moreover, when the side cover is turned over, the locking mechanism will expose sharp protrusions upwards, which is likely to cause problems of operation and safety.

Chinese Invention Patent Publication No. CN108807737A (corresponding to US Patent Publication No. US2018/0315978 A1) discloses a battery wiring module, the cover of which has a cover body part and a cover locking part.

The hinge part is a flexible part, which is formed so as to be integrated with the wall part and the cover body part, respectively, and has a thickness thinner than the thickness of the wall part and the cover body part. The main body of the cover can be rotated between the open position and the closed position covering the upper part of the wiring accommodating part (bus-bar accommodating part and wire accommodating part) centering on the hinge part, and the cover locking part is used for engaging and fixing in the closed position . However, the integrated plastic hinge structure requires the hinge to be deformed and bent when the two lids are opened, resulting in a large reverse lid back force. The two lids are suspended and cannot be fixed in position, and because the two lids are facing The outer side is opened, which will increase the space when the cover is turned, and cause trouble in the operation. In addition, when the two covers are opened, the cover locking part will expose sharp protrusions upward, which is likely to cause problems in operation and safety.
