Embodiment 1

[0025] see Figure 1 to Figure 4 , a warehouse-type battery pack integrated structure for electric vehicles, including a battery assembly 1, a bottom plate assembly 2 for supporting the battery assembly 1, a frame assembly 3 for supporting the bottom plate assembly 2, and an upper cover assembly 4 covering the battery assembly 1 ;

[0026] The frame assembly 3 includes the sill beam assembly 5 located on opposite sides of the battery assembly 1, the front cross plate assembly 7 fixed between one end of the sill beam assembly 5, and the other end of the sill beam assembly 5. Between the rear cross panel assembly 8 and the rear floor assembly 9, the A-pillar assembly 6 fixed on the opposite sides of the front cross panel assembly 7;

[0027] The lower end of the A-pillar assembly 6 is fixedly connected to the door sill assembly 5 .

[0028] The floor assembly 2 includes a floor body 10, a support frame 13 fixed on the edge of the floor body 10, a beam 12 fixed on the upper sid...

Embodiment 2

[0038] This embodiment is basically the same as Embodiment 1, except that the lower side of the upper cover assembly 4 is not provided with a power distribution box bracket or a module pressing plate.

[0039] see Figure 5 to Figure 7 , the outside of the battery module 16 is wrapped with an outsourcing frame 26, and the outsourcing frame 26 is slidably connected to the bottom plate body 10, and the battery module 16 corresponding to the two compartments near the front cross plate assembly 7 is named the front battery module , the other two battery modules 16 are named as the rear battery module, the crossbeam 12 passes through a longitudinal connecting rod 27, and the front battery module and the rear battery module are connected through the longitudinal connecting rod 27, so The longitudinal connecting rod 27 is slidingly connected to the cross beam 12, the longitudinal beam 11 passes through a transverse connecting rod 28, the front battery modules are connected through th...

Abstract

The invention discloses a storage type electric vehicle battery pack integrated structure, and relates to the technical field of new energy automobiles. The structure comprises a battery assembly, a bottom plate assembly used for supporting the battery assembly, a frame assembly used for supporting the bottom plate assembly and an upper cover assembly covering the battery assembly. The frame assembly comprises threshold beam assemblies located on the two opposite sides of the battery assembly, a front transverse plate assembly fixedly connected between one ends of the threshold beam assemblies, a rear transverse plate assembly, a rear floor assembly and A column assemblies fixedly connected to the two opposite sides of the front transverse plate assembly, wherein the rear transverse plate assembly and the rear floor assembly are fixedly connected between the other ends of the threshold beam assemblies. The lower ends of the A column assemblies are fixedly connected to the threshold beam assembly. According to the invention, multiple force transmission ways are provided, when an automobile is impacted, the force is transmitted to the front transverse plate assembly from an automobile head, then part of the force is transmitted to the A column assembly and then to the automobile roof, the stress of the battery is reduced, and the battery is protected.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to an integrated structure of battery packs of storage-type electric vehicles. Background technique [0002] In the development process of electric vehicle technology, users have higher and higher expectations for battery life, and battery power is a key factor in determining the battery life of electric vehicles. [0003] The existing battery pack structure has few force transmission paths. When the front of the vehicle is hit, the force is directly transmitted from the front cross panel assembly to the sill beam assembly, and then to the battery, which is prone to rupture and explosion. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and propose an integrated structure of battery packs for storage-type electric vehicles. [0005] In order to achieve the above object...
