Battery bracket for new energy vehicle

Abstract

The invention belongs to the technical field of automobile parts, and relates to a battery bracket for a new energy vehicle, which comprises a two-point bracket, a battery bracket and a battery, the number of the telescopic beams is at least one, and the telescopic beams are fixedly connected with the two-point bracket; the single-point hanging bracket is vertically arranged, the single-point hanging bracket is fixedly connected with the telescopic beam and the frame, and the telescopic beam can adjust the distance between the two-point bracket and the single-point bracket; the connecting pattern of the two ends of the two-point bracket and the single-point bracket is in the shape of an isosceles triangle, and the battery pack bracket has the advantages of meeting the installation requirements of battery packs of different sizes, and being better in universality and stability.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a battery bracket for a new energy vehicle. Background technique [0002] With the development of automobile energy structure, new energy vehicles have been highly valued and strongly supported by the state due to their advantages of energy saving and environmental protection, high energy efficiency, rich and flexible energy sources, and are becoming more and more popular among people, and have become an important part of modern automobiles. . [0003] The power battery is an energy storage device for new energy vehicles. In order to improve the utilization efficiency of effective electric energy and reduce energy consumption, the national standard has increasingly strict requirements on energy consumption per unit load (Ekg), and the focus is on highlighting the functions of new energy vehicles ( load mass) and performance (energy consumption rate) ratio. For new energy com...

Problems solved by technology

[0004] Due to the large volume and weight of the power battery pack, the traditional brackets are mostly cage or frame structures. The power battery is wrapped and installed on the side of the frame and the upper part of the longitudinal beam. The external space occupies a large amount of parts and data, and the structure is complex. , heavy weight, low manufacturing efficiency, and generally low structural properties such as strength, modal, and fatigue

The battery frame installed in the middle of the longitudinal beam of the vehicle frame is connected to the left and right longitudinal beams at four points, and the span between each installation point is large. When the vehicle frame is twisted, the battery frame and battery pack will be forced to twist and deform, resulting in stress concentration. At the same time, it affects the stability of the internal modules of the battery pack

If elastic connections such as rubber pads are used at the installation point, although the torsion of the battery frame and battery pack can be alleviated to a certain extent, it cannot fundamentally solve the problem. In addition, the modal frequency of the system will be reduced and the probability of vibration problems will increase.

[0005] In addition, the existing power battery frame or bracket is designed based on a one-to-one correspondence with battery packs of fixed shape and size. Because there are certain differences in battery packs from different manufacturers, the bracket cannot be adjusted according to demand, and the adaptability of assembly is poor.
