Rear-hatchback type sliding door device and carriage cargo van with the same

Abstract

The invention relates to a rear-hatchback type sliding door device and a carriage cargo van with the same. The sliding door device comprises a door frame assembly fixed at the rear portion of a carriage, a storage guide rail fixed on the top in the carriage and perpendicular to the door frame assembly, and a back door assembly capable of being opened and closed on the door frame assembly and usedin cooperation with the storage guide rail to be stored on the top of the carriage. The door frame assembly is fixed at the rear portion of the carriage, the storage guide rail is fixed on the top inthe carriage, the storage guide rail is perpendicular to the door frame assembly, the back door assembly can be opened and closed on the door frame assembly and can be used in cooperation with the storage guide rail to be stored on the top of the carriage, and therefore when the back door assembly is opened, the back door assembly and the storage guide rail are located on the same horizontal line,the back door assembly is stored on the top of the carriage along the storage guide rail through external force, and no obstacles exist when a forklift is used; compared with a hatchback door in theprior art, the use limit is broken through, and the rotating speed in logistics is increased; compared with a double door, manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a rear door device for a van, and more specifically relates to a rear hatchback sliding door device and a van logistics vehicle equipped with the same. Background technique [0002] The car back door is one of the important assembly devices of the car body. The back door of the existing van type logistics vehicle is generally a hatchback door type or a double door type; the hatchback door type back door has the advantages of fewer parts, low manufacturing cost, and low assembly requirements, but the opening height of the hatchback door is limited. , the general opening angle is slightly greater than 90°, and the open back door makes it impossible to use a forklift to load and unload goods, so there are great limitations in use and cannot meet the requirements of the logistics industry for fast loading and unloading of goods; The number of parts is large, and the door assembly requirements are high, which...
