Delivery vehicle complete vehicle structure of full-integrated, modularized and total light-weighted structure and vehicle

Abstract

The invention provides a delivery vehicle complete vehicle structure of a full-integrated, modularized and total light-weighted structure and a vehicle, and belongs to the technical field of vehicles.The delivery vehicle complete vehicle structure comprises an aluminum alloy underbed structure, a lateral enclosure structure, a stand partition face structure, a forecabin instrument desk structure,a ceiling structure and connecting rib pieces. The aluminum alloy underbed structure comprises cross beams. The lateral enclosure structure comprises outer frame upper edge beams and outer frame A columns. The lateral enclosure structure is in mortise and tenon joint connection with cross beams. The ceiling structure is in screw joint or mortise and tenon joint connection with the outer frame upper edge beams. The stand partition face structure is in mortise and tenon joint connection with the lateral enclosure structure, the underbed structure and the ceiling structure. The forecabin instrument desk structure is in mortise and tenon joint connection with outer frame A columns. The forecabin instrument desk structure is in threaded connection or welding connection with the underbed structure. The connecting rib pieces are in mortise welding connection with the aluminum alloy underbed structure, the lateral enclosure structure, the stand partition face structure, the forecabin instrument desk structure, and the ceiling structure. The vehicle comprises the structures. The structures are excellent in mechanical property, is low in weight, and the vehicle can be conveniently manufactured and assembled in a modularization mode.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a complete vehicle structure of a logistics vehicle with full load bearing, modularization and light weight structure and an automobile. Background technique [0002] The lightweight of the body structure is the focus of the lightweight of automobiles, especially passenger cars and logistics vehicles. [0003] Aluminum alloy materials are widely used in lightweight body structures due to their low density, high stiffness-to-weight ratio, and abundant material supply. However, several weaknesses of aluminum alloy profiles such as "not easy to bend", "not easy to weld", and "material strength is lower than steel" seriously restrict its application in lightweight car bodies. [0004] In the prior art, steel is generally used for the full load-carrying and modularization of automobiles, but the light weight of steel is low. In the prior art, there is no complete vehicle structu...
