Efficient heat insulation side door of city multi-functional three-temperature distribution vehicles

Abstract

The invention provides an efficient heat insulation side door of city multi-functional three-temperature distribution vehicles. The efficient heat insulation side door comprises a door board and a door frame, a fiberglass protecting extrudate is arranged on the door frame, the fiberglass protecting extrudate is of a frame body structure and arranged outside the door frame, the fiberglass protecting extrudate is of an L-shaped structure, fiberglass edge covering extrudates are arranged on two sides of the outer end of the fiberglass protecting extrudate, and the sections of the fiberglass edge covering extrudates are of an L-shaped structure; the section of a fixing boss is of a square-shaped raised structure, and the fixing boss is arranged on the periphery of one face of the door frame; the door board is in open and close connection with the door frame through hinges, and a locating boss is arranged on the inner side of the door board; a sealing mechanism is arranged on the door board, and the sealing mechanism comprises a first rubber strip, a second rubber strip and sealing rubber strips. By means of the method that the fiberglass protecting extrudate is arranged on the periphery of the door frame in cooperation with the locating boss, effective locating and fixation between the door frame and the door board can be achieved, and abrasion resistance of the outer side of the door frame is greatly improved by using the fiberglass edge covering extrudates. Through the design of the special rubber strip structure, multiple sealing and the excellent heat insulation effect can be achieved.

Description

technical field [0001] The invention relates to a high-efficiency thermal insulation side door of an urban multifunctional three-temperature distribution vehicle. Background technique [0002] Urban distribution is the last mile distribution in the logistics chain, which plays an extremely important role in the entire supply chain. With the adjustment of urban industrial layout, the continuous upgrading of modern consumption patterns, the wide application of e-commerce technology, and The increasingly diverse urban industrial and commercial development models have led to an increasing demand for small-batch, multi-variety, multi-frequency, time-sensitive direct delivery, residential delivery and "door-to-door" delivery, and ordinary vehicles can no longer meet the demand. At present, the thermal insulation door of urban thermal insulation distribution vehicles can be opened and closed hundreds of times a day. The existing thermal insulation doors in China are simple in struc...

[0002] Urban distribution is the last mile distribution in the logistics chain, which plays an extremely important role in the entire supply chain. With the adjustment of urban industrial layout, the continuous upgrading of modern consumption patterns, the wide application of e-commerce technology, and The increasingly diverse urban industrial and commercial development models have led to an increasing demand for small-batch, multi-variety, multi-frequency, time-sensitive direct delivery, residential delivery and "door-to-door" delivery, and ordinary vehicles can no longer meet the demand

At present, the thermal insulation door of urban thermal insulation distribution vehicles is opened and closed hundreds of times a day. The existing thermal insulation doors in China are simple in structure and adopt the design of flat door and door frame. The door and door frame are prone to gaps during use, and the thermal insulation performance is poor.
