The invention discloses a novel pure electric bus body structure. A front door and a rear door are formed in the front suspending section and the rear suspending section of a bus body. A whole bus is of a whole-bearing-type low floor structure. Two power battery boxes are respectively of a vertical structure. The left power battery box (4) and the right power battery box (5) are arranged above wheel packages of rear wheels (3) at the inner sides of a side wall. A lower air inlet (12) is formed in the lower portion of each power battery box and an upper air outlet (13) is formed in the upper portion of each power battery box. The portions, corresponding to the lower air inlets of the power battery boxes, of the side wall are provided with side wall lower air inlets (7) and the portions, corresponding to the upper air outlets of the power battery boxes, of the side wall are provided with side wall upper air outlets (8). The portions, corresponding to the power battery boxes, of the side wall are provided with a detachable side wall frame (9) and a side wall bearing structure is formed by an overall bus body side wall frame (6) and the detachable side wall frame (9). After the side wall frame is detached, the battery boxes can be taken out through a forklift out of the bus, and maintenance of the battery boxes is convenient; due to the detachable side wall frame, the battery boxes can be protected; meanwhile, continuous transmission of a load is guaranteed through the detachable side wall frame and the detachable side wall frame is reinforced.
Description
technical field [0001] The invention relates to a vehicle body structure proposal with a novel battery box and a detachable side wall. technical background [0002] Usually, the power battery of a pure electric bus is arranged on the rear suspension of the vehicle frame or under the seat. For example, the patent with the publication number CN1439543 discloses a chassis of an electric bus, and the power battery is installed on both sides of the middle and the rear of the vehicle frame. The battery is located in the lower part of the floor, the cooling effect is poor, and it is not easy to disassemble and maintain. At the same time, when the power batteries of some electric buses are arranged closer to the outside of the vehicle body, they lack corresponding protective measures and cannot withstand external impacts on the batteries. Contents of the invention [0003] Aiming at the problems of poor heat dissipation and inconvenient installation and maintenance of the existin...
