Problems solved by technology

[0004] However, since the adhesive is injected between the peripheral side wall of the shield frame and the inner wall surface of the outer frame, the adhesive cannot be spread, so there is a problem that the airtightness deteriorates
On the other hand, in order to ensure the airtightness of the above-mentioned structure, it is difficult to determine the positions of the cover frame and the outer frame frame with high precision and to bond them together.
Furthermore, since it is difficult to visually confirm the airtightness of the adhesive, there is a problem that inspection is difficult

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] as attached figure 1 , 2 As shown, the battery pack frame of the present invention includes a movable plug-in frame body for placing battery components, a cover plate 1, a bottom plate 2, and side plates 3 on the front, rear, left, and right sides; the movable plug-in frame body It is mainly composed of several straight beams 11, straight longitudinal beams 12, and straight vertical beams 13, which are spliced ​​together through corner connectors 14. The straight beams 11, straight longitudinal beams 12, and straight vertical beams 13 are all made of extruded aluminum profiles; the corner connectors 14 are castings, and the side plates 3 are plugged into the four-sided side frame of the combination of the straight beams 11 and the straight vertical beams 13. The bottom plate 2 It is plugged into the lower frame of the combin...

Abstract

The invention relates to a battery pack frame, which comprises a movable plug-in type frame body used for the placing of battery modules, wherein the movable plug-in type frame body is mainly formed by splicing a plurality of linear cross beams, linear longitudinal beams and liner vertical beams through corner connecting pieces. According to the scheme provided by the invention, the linear cross beams, the linear longitudinal beams and the liner vertical beams are plugged in and spliced to form the movable plug-in type frame body, and according to the required size dimension of the battery frame, the linear cross beams, the linear longitudinal beams and the liner vertical beams with different length dimensions are selected and are then spliced and fixed through the corner connecting pieces, so that a battery pack has extensibility, the development of a mold is reduced, and the installation dimension requirements of different vehicle models are met; in addition, the battery pack frame is convenient to install and disassemble, and the economic benefit of the battery pack frame is improved.

Description

technical field [0001] The invention relates to the technical field of new energy electric vehicle battery packs, in particular to a battery pack frame. Background technique [0002] With the country's strong support for new energy industry policies, domestic and foreign companies continue to increase research and development efforts in new energy vehicles. New energy vehicles are booming, and electric vehicle technology is becoming increasingly mature. At present, the national standard is still in the draft for comments. With the subsequent development of the industry, it is imperative to standardize the size of the battery pack. Therefore, the structural design of the battery pack must follow the requirements of the national standard consultation draft, reasonably formulate the size parameters of the battery pack, and flexibly determine the installation position of the battery pack. The currently used battery pack outer frame processing technology is die-casting (aluminum)...
