Chassis structure of electric automobile

Abstract

The invention provides a chassis structure of an electric automobile. The chassis structure of the electric automobile comprises a honeycomb accommodating structure, a battery assembly, a pedestal assembly and a convergence row assembly; the convergence row assembly comprises a positive electrode convergence layer and a negative electrode convergence layer positioned on the positive electrode convergence layer; the honeycomb accommodating structure is arranged above the negative electrode convergence layer; the positive electrode of each single-body battery is electrically connected with the positive electrode convergence layer through an elastic connecting piece and a protecting piece arranged on the positive electrode convergence layer; and the negative electrode of the single-body battery is electrically connected with the negative electrode convergence layer through a conducting connecting piece accommodated in the pedestal assembly. The chassis structure of the electric automobile, which is provided by the invention, realizes non-wiring-harness connection between the single-body batteries through the convergence row assembly and maximally simplifies the circuit structure; anda bolt welding structure is omitted and the use safety of each single-body battery is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle chassis structure. 【Background technique】 [0002] Under the pressure of energy crisis and environmental pollution, safety, environmental protection, and energy saving have become the themes of today's automobile development. Electric vehicles have been highly valued and supported by transportation and energy departments because of their advantages in energy saving, environmental protection, and pollution-free. In recent years, The new energy automobile industry ushered in explosive growth. Batteries are the core of electric vehicles. At present, the installation of batteries is carried out by bolt connection or welding, and then the series and parallel connections between batteries and battery modules are realized through complex wiring harness structures. This confluence design, welding level and bolt The installation requirements are high and t...

Problems solved by technology

Batteries are the core of electric vehicles. At present, the installation of batteries is carried out by bolt connection or welding, and then the series and parallel connections between batteries and battery modules are realized through complex wiring harness structures. This confluence design, welding level and bolt The installation requirements are high and there are too many battery harnesses, the circuit structure is complex, the circuit reliability is poor, and the installation and maintenance are inconvenient
