Description

Battery pack of new energy automobile

Technical Field

The invention relates to the technical field of key parts of new energy automobiles, in particular to a battery pack of a new energy automobile.

Background

The battery pack is a very important component in a new energy automobile. Whether a purely electric vehicle or a hybrid vehicle, is equipped with a battery pack. In fact, a battery pack is formed by splicing a plurality of storage battery units which are connected in series in an S shape. Then the both sides of group battery set up the sideboard, through the nut all with many battery unit one-to-one connect on this sideboard to structurally realize piecing together battery unit. Thus, when one of the battery cells is replaced, the nut is first removed from the edge plate. Thus, the efficiency of replacing the battery cells is low.

Disclosure of Invention

The invention aims to provide a battery pack of a new energy automobile, which can be quickly disassembled.

The technical scheme of the invention is that the battery pack of the new energy automobile comprises a bottom frame, a left side plate and a right side plate are respectively arranged at the left end and the right end of the bottom frame, a plurality of storage battery units are arranged between the left side plate and the right side plate, electrodes of the storage battery units are arranged at the same height in a straight line shape, a first side hole and a second side hole which are opposite in the arrangement direction of the electrodes are respectively arranged on the left side plate and the right side plate, side rods penetrate through the first side hole and the second side hole, a plurality of extrusion grooves which are corresponding to the positions of the electrodes one by one are arranged on each side rod, sliding grooves which are positioned at one side of the extrusion grooves and along the arrangement direction of the electrodes are also arranged on the side rods, sleeve caps which can move along the length direction of the electrodes are arranged on the electrodes, and compression blocks which protrude and are embedded into the extrusion grooves are arranged on the sleeve caps, when the side rod moves along the arrangement direction of the electrodes, the extrusion groove moves to extrude the pressed block to separate the sleeve cap from the electrodes; the sleeve cap is further provided with a side strip extending to the position where the sliding groove is located, the end portion of the side strip is connected with a sliding block in the sliding groove through a tension spring, and when the sleeve cap is separated from the electrodes, the sliding block slides along the arrangement direction of the electrodes to enable the opening direction of the sleeve cap to be still maintained in the length direction of the electrodes.

Compared with the prior art, the invention has the advantages that the side rod is movable in the first side hole and the second side hole, and the movable direction is the arrangement direction of the electrodes, which is different from the traditional battery pack that the electrodes are arranged on the fixed side plate through nuts. When the side bar moves from left to right, the pressing grooves move synchronously. The extrusion groove moves to extrude the compression block with the convex cam surface structure so that the sleeve cap sleeved on the electrode is gradually separated from the electrode. In the process, the slide block also moves in the slide groove so that the opening direction of the sleeve cap is still maintained in the length direction of the electrode. The opening direction of the sleeve cap is maintained in the length direction of the electrode, and the sleeve cap can be smoothly separated from the electrode. Therefore, when the side rod is pushed to move, the sleeve cap is separated from the electrode, and then the battery unit is released from being fixed, so that the quick disassembly is realized.
