Description

Technical Field

[0001] The utility model relates to the technical field of new energy refrigerated vehicles, in particular to a new energy commercial refrigerated logistics vehicle compartment. Background Art

[0002] New energy commercial vehicles refer to all new energy cargo logistics vehicles and new energy buses with more than nine seats. At present, the application scenarios of new energy commercial vehicles are mainly concentrated in the fields of construction machinery, mining excavation and transportation, road transportation, urban distribution logistics, etc. In modern urban life, many large-scale logistics, express delivery, fresh fruits, etc. require urban distribution logistics. In order to promote the development of green urban distribution logistics industry, new energy commercial vehicles are widely used in logistics and distribution.

[0003] For items such as fresh fruits that require low-temperature storage and cold chain transportation, new energy commercial vehicles are generally modified for loading and transportation. By installing polyurethane or extruded polystyrene foam panels and insulated tailgate walls in the original compartment, the compartment has an insulation effect. In order to facilitate the placement of goods, some vehicles are equipped with a middle door on the side of the compartment. The frequent opening and closing of the middle door also increases the rate of temperature loss. Therefore, some merchants choose to add an insulation wall to the middle door. However, the addition of insulation materials and insulation walls further reduces the cargo space of the compartment itself and reduces the transportation volume, which increases the user's single-item single-trip transportation costs and increases the cost of the transportation company. Utility Model Content

[0004] In order to improve the cargo space and thermal insulation transportation effect of new energy commercial vehicles, the utility model provides a new energy commercial refrigerated logistics compartment.

[0005] This application provides a new energy commercial refrigerated logistics carriage, which adopts the following technical solutions:

[0006] A new energy commercial refrigerated logistics carriage comprises a carriage body, one side of the carriage body is provided with a middle opening for taking and placing goods, a middle door with an insulation board is provided at the middle opening, and a middle door sealing assembly is provided between the middle door and the carriage body.

[0007] By adopting the above technical solution, the middle opening improves the convenience of taking and placing goods. When the middle door is closed, the middle door sealing assembly seals the middle door and the vehicle body, so that the goods can reach the middle door when loading. The middle door sealing assembly reduces the rate of temperature loss to increase the thermal insulation effect of the vehicle body, thereby improving the loading space and thermal insulation transportation effect of the new energy commercial vehicle.

[0008] Optionally, the middle door sealing assembly includes:

[0009] A middle door sealing strip, which is annular and arranged around the middle opening;

[0010] A second encryption rubber strip, which is annular and located at the inner ring of the middle door sealing strip, is sealed and connected to the side wall of the carriage body through a bracket, and has a shelter opening at the bottom of the second encryption rubber strip for conveniently taking in and putting in goods;

[0011] The third encryption rubber strip extends horizontally and is located at the object shelter. Both ends of the third encryption rubber strip are respectively connected to the second encryption rubber strip. The third encryption rubber strip is sealed to the side wall of the carriage body through a connecting frame and protrudes outward from the side wall of the carriage body.

[0012] By adopting the above technical scheme, the middle door sealing strip performs preliminary sealing between the middle door and the car body, the second encryption strip performs secondary sealing between the two side walls and the top wall of the middle door and the car body, and the third sealing strip performs secondary sealing between the bottom wall of the middle door and the car body. The double sealing improves the sealing effect between the middle door and the car body, reduces the rate of temperature loss, and does not require additional insulation walls. When an insulation wall is set, the thickness of the insulation wall can also be reduced. At the same time, the middle door sealing strip, the second sealing strip and the third sealing strip provide a buffer when the middle door is closed, thereby improving the insulation transportation effect of the new energy commercial vehicle.

[0013] Optionally, the vehicle body includes a vehicle body wall, a heat-insulating composite layer and a thermoplastic skin which are arranged in sequence from the outside to the inside.

[0014] By adopting the above technical solution, the body wall and the thermoplastic skin cooperate to increase the transportation space of the carriage, reduce the weight of the carriage body, and cooperate with the thermal insulation composite layer to reduce the probability of temperature loss.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] The middle door sealing strip performs preliminary sealing between the middle door and the car body, the second encryption strip performs secondary sealing between the two side walls and top wall of the middle door and the car body, and the third sealing strip performs secondary sealing between the bottom wall of the middle door and the car body. The double sealing improves the sealing effect between the middle door and the car body, reduces the rate of temperature loss, and does not require additional insulation walls, thereby improving the insulation transportation effect of new energy commercial vehicles.
