Battery replacement assembly for vehicle and battery replacement method thereof

Abstract

The invention provides a battery replacement assembly for a vehicle and a battery replacement method thereof, and relates to the technical field of a chassis. The battery replacement assembly comprises two fixing structures located on the two sides, in the transverse direction of the vehicle, of a transverse and longitudinal beam assembly respectively and fixedly connected with the two vehicle body longitudinal beams respectively, and a transfer structure detachably arranged below the transverse and longitudinal beam assembly and the two fixing structures. A first accommodating space is defined in the fixing structures, a second accommodating space is defined in the transfer structure, a third accommodating space is defined among the transfer structure, the two fixing structures and the transverse and longitudinal beam assembly, and the first accommodating space, the second accommodating space and the third accommodating space are all used for accommodating battery packs; and the top of the transfer structure and the bottom of each fixing structure are open so that the battery packs contained in the first accommodating space, the second accommodating space and the third accommodating space are all supported on the transfer structure. The battery replacement assembly provided by the invention is reasonable in battery space arrangement and can realize bottom battery replacement.

Description

technical field [0001] The invention relates to the technical field of chassis of vehicles, in particular to a battery swapping assembly for a vehicle and a battery swapping method thereof. Background technique [0002] The batteries of pure electric vehicles for non-load-bearing commercial vehicles are arranged on both sides of the longitudinal beams, and the drive shaft and Yuanbao beam are arranged between the two longitudinal beams. At present, the standard box layout on the market can accommodate a maximum battery power of 282kwh and a mileage of no more than 150km, resulting in a small driving radius, which is not conducive to the promotion of new energy vehicles. At present, there are two modes of battery replacement for commercial vehicles on the market: one is side-to-side battery replacement, and the other is top-lifting battery replacement. The side-to-side battery replacement mode needs to be equipped with rollers, guides, positioning and locking on the vehicle....

AI Technical Summary

Problems solved by technology

The side-to-side battery replacement mode needs to be equipped with rollers, guides, positioning and locking on the vehicle. The structure is complex, the cost is high, and the failure rate is high, which increases the risk of vehicle operation; the top-lifting battery replacement mode is to lift the battery box above the vehicle. Since the power of the heavy truck is high and the height of the battery box is high, it is necessary to lift the battery box to a higher height, which greatly increases the risk of battery replacement.

Therefore, there are many unreasonable things in the prior art whether it is the arrangement of battery packs or the way of battery replacement.
