Universal modular chassis structure for new energy automobile

Abstract

The universal modular chassis structure comprises a left chassis body, a right chassis body, protective side strips, connecting pieces, openings, auxiliary stabilizing devices and protective structures, the protective structures are arranged at the bottoms of the left chassis body and the right chassis body, foam layers and rubber layers are arranged in the protective structures, the flexibility is good, the energy absorption effect is strong, and the service life is prolonged. The aramid fiber layer is arranged at the bottom of the rubber layer, so that the wear resistance is good, the impact resistance effect is good, and stable protection is achieved; an auxiliary stabilizing device is arranged at the connecting position of the inner sides of the left chassis and the right chassis, and a supporting rod in the auxiliary stabilizing device is matched with fixing of a connecting arm, so that the connecting position of the two chassis is effectively stabilized, and falling is avoided; and the stabilizing mechanism is arranged in the auxiliary stabilizing device, four groups of cooling discs are arranged in the stabilizing mechanism, the cooling discs effectively press and fix the battery, and rapid heat conduction of the battery can be realized by matching with connection of an external circulating water cooling pipe.

Description

technical field [0001] The invention relates to the related field of new energy vehicle chassis, in particular to a general-purpose modular chassis structure for new energy vehicles. Background technique [0002] At present, the body of new energy vehicles is the same as the body of ordinary fuel vehicles. It is an integral structure. The layout design of each system is still designed on the basis of the traditional chassis. Although the structural integrity is good, this kind of The structure will increase the difficulty of parts layout and bracket design, resulting in waste of space design, waste of materials, increase of vehicle weight and cost, and the new energy modular chassis based on traditional chassis will increase the cost of transformation , and the restructuring space is limited, restricting production capacity. [0003] In the actual use of the existing modular chassis structure common to new energy vehicles, when the chassis at both ends are connected, a simp...

Problems solved by technology

[0002] At present, the body of new energy vehicles is the same as the body of ordinary fuel vehicles. It is an integral structure. The layout design of each system is still designed on the basis of the traditional chassis. Although the structural integrity is good, this kind of The structure will increase the difficulty of parts layout and bracket design, resulting in waste of space design, waste of materials, increase of vehicle weight and cost, and the new energy modular chassis based on traditional chassis will increase the cost of transformation , and the restructuring space is limited, restricting production capacity

[0003] In the actual use of the existing modular chassis structure common to new energy vehicles, when the chassis at both ends are connected, a simple fixing method is used for connection, resulting in the hidden danger of falling off after the connection, and it is harmful to the stability and protection of the battery. less effective
