A special high-efficiency airbag sealing strip for urban multi-functional three-temperature delivery vehicles

Abstract

The invention discloses an efficient air bag sealing rubber strip special for a multifunctional urban three-temperature distribution vehicle. The efficient air bag sealing rubber strip comprises a sealing connecting strip and two sealing parts; the two sealing parts are arranged at the two ends of the sealing connecting strip respectively, and each sealing part comprises a supporting part and an air bag part, wherein the supporting part comprises two special-shaped rubber strips, the air bag part comprises a flat-plate-shaped rubber strip and a semi-circular-ring-shaped rubber strip, the two ends of the bottom of the flat-plate-shaped rubber strip are connected with the tops of the special-shaped rubber strips, the two ends of the top of the flat-plate-shaped rubber strip are connected with the two ends of the bottom of the semi-circular-ring-shaped rubber strip, the flat-plate-shaped rubber strip and the semi-circular-ring-shaped rubber strip are integrally connected to form a special-shaped ring structure and connected to form an air bag cavity of which the section is shaped like an irregular circle in an enclosing mode, and a door edge contact protrusion is arranged on the top of the semi-circular-ring-shaped rubber strip. Accordingly, multiple sealing is achieved by adopting the special structural design of the rubber strip, and then an extremely good heat preservation effect can be achieved.

Description

technical field [0001] The invention relates to a high-efficiency airbag sealing strip specially used for urban multifunctional three-temperature distribution vehicles. 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, in urban thermal insulation distribution vehicles, the thermal insulation door opens and closes hundreds of times a day. The existing thermal insulation door in China has a simple structur...

[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 door in China has a simple structure, and gaps are likely to occur between the door and the door frame during use, and the thermal insulation performance is poor.
