Triangular loop chain type bus body structure of full-load pure-electric double-layer tourist bus

Abstract

The invention discloses a triangular loop chain type bus body structure of a full-bearing pure-electric double-layer tourist bus, which is composed of six sub-assemblies, comprising a front wall, a rear wall, a left side wall, a right side wall, a first-layer underframe and a second-layer underframe, wherein each sub-assembly is of a space truss structure composed of small-section rod pieces; thefirst-layer bottom frame is composed of a first upper-layer framework, a first lower-layer framework and a first supporting piece. The first upper-layer framework is composed of a first upper rectangular supporting main frame, a triangular link chain A and a first upper auxiliary frame; a plurality of small upright posts are arranged at the crossed position of the triangular loop chain A and the first inclined strut group; the second-layer bottom frame is composed of a second upper-layer framework, a second lower-layer framework and a second supporting piece; the second upper-layer framework is composed of a second upper rectangular supporting main frame, a triangular link chain B and a second upper auxiliary frame. Through the design of the triangular loop chain type supporting frame, a force transmission chain in the driving direction is formed, the impact resistance is improved, and meanwhile the longitudinal bearing capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of double-decker bus structure design, and in particular relates to a triangular chain-type body structure of a full-carrying pure electric double-decker tourist bus. Background technique [0002] In recent years, my country's environmental protection requirements have become higher and higher, and the new exhaust emission standards have become more and more stringent. The new energy market has attracted the attention of many car companies. As a type of pure electric vehicles, pure electric sightseeing minibuses have the advantages of zero pollution and zero emissions. Compared with traditional cars, they can also enjoy state subsidies, replace traditional sightseeing cars, and solve the current difficulties encountered by traditional sightseeing cars. It is beneficial to protect the environment; and with the continuous improvement of new energy battery technology, new energy vehicles will be further widely ...

AI Technical Summary

Problems solved by technology

However, due to the frequent operations of starting, stopping, idling, etc. during driving, the pure electric sightseeing car frequently impacts its body structure in the direction of travel, which in turn causes the body structure to wear out quickly and greatly shortens the life of the body.
