A special closed door panel for urban multi-functional three-temperature distribution vehicle

Abstract

The invention relates to a special closed door plate for an urban multifunctional three-temperature distribution vehicle. The closed door plate comprises a left door plate and a right door plate, wherein the left door plate comprises a left door frame and a polyurethane door body; the left door frame comprises an upper profile, a lower profile, an outer profile and an inner profile; the upper profile comprises a first vertical plate, a horizontal plate and a second vertical plate; notches are formed at the two ends of the two vertical plates; the inner profile comprises a first horizontal plate, a first inclined plate and a second horizontal plate; a foam plate is arranged inside the polyurethane door body; a five-layer plywood is arranged between the foam plate and an outer skin; second embedded iron is arranged on the foam plate, the upper profile and the lower profile; an inner profile of the right door plate comprises a second inclined plate; the second inclined plate and the first inclined plate are arranged in parallel to each other. The closed door plate has high rigidity, can achieve interlocking of the left and right door plates and is beneficial to improving the closeness and thermal insulation performance of the carriage of the three-temperature distribution vehicle, thus reducing the refrigeration energy consumption and prolonging the service life.

Description

technical field [0001] The invention relates to a special closed door panel for an urban multifunctional three-temperature distribution vehicle, which belongs to the technical field of cold chain logistics equipment. Background technique [0002] With the advancement of science and the rapid development of the cold chain logistics market, the low-temperature logistics process based on refrigeration technology and refrigeration technology as a means can ensure food quality and reduce food loss. According to the needs of different users and product quantities, a multi-functional three-temperature delivery vehicle came into being. The three-temperature compartment uses movable soft partitions to divide the interior of the compartment into three temperature zones, namely the refrigerated zone, the frozen zone and the normal temperature zone. The zone is the area for storing and transporting fresh goods, the freezing zone is the area for storing and transporting frozen products, ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional structure, the upper end surface, the lower end surface and the inner vertical edge of the door leaf are sealed with a sealing strip with a slope. Due to the high requirements for the sealing and sealing performance of the three-temperature compartment, the existing door panel is used for a long time due to the defect of the profile. In the process, it is easy to wear and deform, which cannot meet the demand, which will easily lead to the loss of cold air in the box, reduce the thermal insulation performance, increase the refrigeration pressure and energy consumption of the refrigeration components, thus limiting the use of three-temperature distribution vehicles, and the door panels are rigid especially when used as the rear door of the compartment The strength and thermal insulation effect cannot be demanded, thus reducing the service life
