Problems solved by technology

[0006] However, due to the poor toughness and poor wear resistance of composite materials, it is often necessary to use a huge amount of material when used as a base plate, which directly leads to the loss of weight reduction advantages of composite materials in the base plate.

Abstract

The invention provides a wear-resistant and impact-resistant logistics carriage bottom plate which comprises a double-web grating and a panel, the lower surface of the panel is a smooth welding surface, the double-web grating and the lower surface of the panel are welded and fixed, and the double-web grating is formed by mutually overlapping and fixing crisscrossed U-shaped groove-shaped ribs. According to the invention, starting with material selection and structural design, a feasible design scheme is provided, under the condition that the logistics carriage bottom plate also meets the use working condition of the logistics vehicle; compared with a traditional steel structure, the weight is reduced by 60% or above, compared with a traditional thermosetting resin-based composite material,the composite material has a better weight reduction effect, meanwhile, higher wear resistance and impact resistance are provided, the transportation efficiency of the logistics vehicle is improved to a great extent, the service life of a compartment is prolonged, and economic benefits are greatly improved. The bottleneck problem of light weight of the logistics carriage bottom plate is solved, and then the overall light weight degree of the vehicle is increased.

Description

technical field [0001] The invention belongs to the technical field of logistics carriages, and in particular relates to a wear-resistant and impact-resistant logistics carriage bottom plate. Background technique [0002] In developed countries in Europe and America, composite materials have been widely used to replace other non-environmentally friendly materials. DHL, FEDEX, UPS, and TNT, the four major international express companies, have replaced other material carriages with composite carriages on a large scale. [0003] Research on the application of composite materials in logistics vehicles in my country has been carried out for several years. In Hong Kong, composite materials have been designated by SF Express as special materials for carriages. In China, SF Express, Debon, Usu, Best Huitong, etc. have taken the lead in applying composite material compartments to newly purchased vehicles, and have achieved great praise in practical applications. [0004] At this st...
