Problems solved by technology

[0004] (1) Not conducive to lightweight: the existing battery cover is basically made of 3-5mm FRP as the skin, and square steel as the supporting frame. The parts are large in size and the overall weight is heavy
[0005] (2) Poor environmental protection: Most of the existing battery covers are made of glass fiber reinforced plastics, and the manufacturing process and scrapping treatment are likely to cause environmental pollution and have no recycling value
[0006] (3) Difficult maintenance: the top cover of the power battery and the space inside the battery cover are limited. To replace the parts inside the cover, the entire cover needs to be disassembled. The workload is large, and it is not easy to maintain during debugging and use.
[0007] (4) High cost: Different specifications and shapes require different FRP molds, and the cost of the mold keeps the price high

Abstract

The invention belongs to the technical field of new energy passenger cars, and particularly discloses a lightweight aluminum alloy battery cover which is mainly made of aluminum profiles and comprises a cover body frame, a front end face, a rear end face, a top access door and side access doors. The front end face and the rear end face are fixed to the cover body frame in a bonding or welding mode, the top access door is fixed to the upper end face of the cover body frame through hinges, and the side access doors are fixed to the left end face and the right end face of the cover body frame through hinges. The cover body frame is of a cubic structure, the transverse frame is a cross beam, the longitudinal frame is a side longitudinal beam, the vertical frame is a side stand column, a middle longitudinal beam is arranged on the upper end face of the cubic structure, a front stand column is arranged between the front end face and the rear end face, and a middle cross beam is further arranged on the upper end face. The cover body frame is formed through integral welding. The structure is simple, the design is reasonable, the special section design meets the requirements of modeling, functions and the like, meanwhile, the top access door and the side access door enable maintenance to be convenient, the production efficiency is improved, and the production and use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy passenger cars, and in particular relates to a lightweight aluminum alloy battery cover. Background technique [0002] With the rapid development of new energy buses, pure electric vehicles and hydrogen fuel cells are widely used in the design. The low-floor, low-entry chassis structure design reduces the floor height inside the car, and at the same time facilitates passengers getting on and off the car, increases the space utilization rate inside the car, and improves the ride comfort of passengers. The above changes have made the top-mounted power battery system a trend. With the increasingly fierce market competition, the appearance of buses has been updated more frequently, including the top-mounted battery cover and other components. In order to meet the conditions of dustproof, rainproof, heat preservation, and convenience Maintenance, the market urgently needs a cover structure with str...
