Embodiment Construction

[0025] In conjunction with accompanying drawing, the present invention is described in further detail:

[0026] Body structure such as figure 1 As shown, the doors are opened on the front and rear suspension sections, both low-floor axles and ordinary axles can be used.

[0027] mid-body figure 2 , 3 As shown in the side view, the side wall and the underframe adopt a complete truss structure. The diagonal braces of the truss structure are arranged in an inverted triangle, and the angle can be adjusted according to the specific stress situation. These 4 complete truss structures form a whole with extremely strong bearing capacity. The side truss height H 1 and chassis truss height H 2 Consistent, with a maximum deviation of no more than 10%, ie: In order to ensure that the ultimate deformation of the two is relatively close under the action of their respective maximum loads, the stiffness characteristics of the frame and side walls can be matched to a better state, and...

Abstract

The invention relates to a novel car body structure of a full-loaded purely electrical passenger car. In the car body structure of the full-loaded purely electrical passenger car, a passenger front door (1) and a passenger rear door (2) are formed in the front and rear sections of the car body; integral diagonal brace girder structures (6) and (8) are formed in the part between the upper and lower waist beams of the side body and the middle keel part of the car body; the upper and lower waist beams (3) and (4), lower side beams (5) and a keel longitudinal beam (15) are communicated; a motor is arranged in the middle; and a power battery packs are arranged in the middle section of the car body. The structure is a whole, and the middle section of the car body has high carrying capacity. The structure is optimized by a full-loading technique, so the non-axial loads of the rod pieces of the structure are reduced effectively, the stress of the members of the structure are more reasonable, and the load distribution is more uniform. Therefore, the strength and rigidity of the car body are both improved effectively.

Description

technical field [0001] The invention relates to a novel full-load pure electric bus body structure. technical background [0002] Automobile is one of the symbols of modern industrial civilization. Since its birth, it has brought great convenience to people's production and life, but it has also brought a series of negative effects. The environmental pollution caused by automobiles and the excessive consumption of energy by automobiles are two prominent problems. The development of new energy vehicles has become an inevitable trend. Among them, pure electric vehicles have been rated as the most promising new energy vehicles by experts due to their many advantages such as no pollution, low noise, high energy efficiency, and diversified energy sources. [0003] According to my country's national conditions, the research and development of electric buses is an entry point for the development of pure electric vehicles, because the development of pure electric buses has the fol...
