Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a structural view of the lower case of the battery pack of the present invention

An intent; fig. 3 is a schematic structural view of the battery case upper cover of the present invention.

As shown in fig. 1, the capacity-increasing type battery box comprises a battery box lower shell 1, a battery box upper cover 2 and a clamping groove 3, wherein the battery box lower shell 1 and the battery box upper cover 2 are matched with each other and fixedly connected together, the clamping groove 3 is arranged on the outer side of the battery box lower shell 1, the battery box lower shell 1 is composed of a first quadrilateral frame 11, a second quadrilateral frame 12 and a triangular frame 13, and the end face of the first quadrilateral frame 11 and the end face of the second quadrilateral frame 12 are respectively located on two adjacent side faces of the triangular frame 13.

The lower case 1 and the upper cover 2 are integrally formed.

One side of the lower shell 1 of the battery box is provided with a first folded edge 4, one side of the upper cover 2 of the battery box is provided with a second folded edge 5, and a C-shaped clamping groove 3 is formed between the first folded edge 4 and the second folded edge 5.

Referring to fig. 2 and 3, a plurality of studs 6 are fixed on the inner side wall of the lower battery case shell 1, a plurality of through holes 7 for allowing the studs 6 to pass through are formed in the upper battery case cover 2, and the lower battery case shell 1 is fixedly connected with the upper battery case cover 2 through the studs 6 and nuts which are connected together through threads.

Because the end face of the first quadrangular frame body 11 and the end face of the second quadrangular frame body 12 are respectively positioned on two adjacent side faces of the triangular frame body 13, a folded angle is formed between the first quadrangular frame body 11 and the second quadrangular frame body 12, so that an L-shaped battery box is formed, the vertical space and the rear space in the vehicle can be fully utilized, and the box internal capacity of the battery box is improved.

The current battery case is whole stamping forming, and this kind of processing mode cost is higher. And this application makes casing and upper cover separately, and final assembly connects, and this kind of mode just can make battery case lower casing 1 and battery case upper cover 2 through injection moulding to the cost has been practiced thrift. And the clamping groove 3 at the side end of the battery box can be used for inserting aluminum strips in a vehicle and installing the battery box in the vehicle. On one hand, the stud 6 can be matched with a nut to be used for connecting the battery box lower shell 1 and the battery box upper cover 2, and the structural strength of the battery box lower shell 1 can be improved through the stud 6. The stiffening plates used for forming the triangular frame body 13 can improve the structural strength of the whole battery box, the triangular frame body 13 plays a role in reinforcement, and a protection plate can be placed in a cavity of the triangular frame body 13.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
