Description

Removable EV battery bracket

technical field

The utility model relates to a battery installation structure of a pure electric vehicle, in particular to a detachable electric vehicle battery bracket.

Background technique

The current development of pure electric vehicles is still limited by batteries. Restricted by the development of battery technology, most of the battery boxes are cuboid, large and heavy. Due to the impact of the vehicle's cruising range and driving conditions, when high power is required, usually when there are multiple large battery packs, the upper and lower layers are often arranged, and the upper battery bracket and the lower battery bracket are often welded as a whole. The upper battery pack can be installed vertically from top to bottom using mechanical tools, while the installation of the lower battery is affected by the bracket structure and can only be pushed from the side by manpower. In response to this phenomenon, most of the methods currently used to reduce the surface friction of the bottom bracket, such as polishing, installing guide grooves and balls. However, in the face of large and heavy battery boxes, these installation methods are not effective and inefficient.

Contents of the invention

The purpose of the utility model is to provide a detachable electric vehicle battery bracket, which can meet the requirement of force strength in structure and meet the requirement of space in installation.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is as follows: the detachable electric vehicle battery bracket includes a frame body, and the frame body is divided into an upper layer and a lower layer. Brackets are arranged symmetrically on the side, beams are set between the longitudinal beams of the upper frame body and the lower frame body, support rods are provided between adjacent beams, and multiple round holes are set on the beams of the lower frame body, and the middle part of the bracket An inner support frame is provided, and a group of vertically symmetrical L-shaped supports are vertically provided at the top corners of the upper frame body.

Improvement to the above technical solution: the bracket, the lower frame body and the upper frame body are welded together with reinforcing ribs.

A further improvement to the above technical solution: reinforcing ribs are provided at the top corners of the lower frame body and the upper frame body.

Beneficial effect:

The detachable electric vehicle battery bracket described in the utility model can meet the requirements for battery installation, has high strength and light weight, and meets the requirements for light weight of the whole vehicle while meeting the force requirements.

detailed description

The electric vehicle battery bracket of the utility model is shown in figure 1 and figure 2. Bracket 1 is divided into upper and lower layers 2, 3, wherein, the front and rear of lower frame body 3 are special-shaped plate brackets 1 after bending and processing of steel plates, the longitudinal beam 4 and cross beam 5 adopt channel steel, and the top of cross beam 5 of lower frame body 3 is opened. There are a plurality of circular holes to reinforce the structure while reducing the weight, and a rectangular steel pipe support rod 6 is added between two adjacent beams 5 . Considering that the weight structure is long and the force in the middle part is similar to the cantilever structure, the inner support frame 7 of the special-shaped plate is added in the middle to ensure the strength and also the connection between the bracket 1 and the workshop is firm and reliable. Take full welding between the longitudinal beam 4, the cross beam 5, the support rod 6, and the special-shaped plate bracket 1, and connect them. Among them, the crossbeam 5 and the longitudinal beam 4, and the longitudinal beam 4 and the special-shaped plate 1 are welded together with reinforcing ribs, so that all parts of the entire battery bracket form a whole, so that its strength and force are satisfied. The vertical fixed side columns on both sides of the upper frame body 2 are welded together by four rectangular steel pipes, considering a tension situation of the upper layer frame body 2 to the columns on both sides. The bottom of the vertically fixed column is welded together with the beam 5 and the longitudinal beam 4 of the lower frame body 3, and the side is welded together with the side of the special-shaped plate bracket 1. The longitudinal beams 4 and cross beams 5 of the upper frame body 2 are all connected together by full welding of rectangular steel pipes, and the top corners are also connected with reinforcing ribs. There are four corners of the upper frame body 2, and each corner has an L-shaped support 8 up and down. Adopt high-strength bolts to fix between the L-shaped support 8 and the vertical fixed column. In order to keep the width of the battery bracket from being too wide, the pin positioning on one side is canceled and the bolts on both sides are used to fix it. Of course, if the battery pack structure requires it, it can also be evolved into a pin and bolt fixing method.
