Abstract
Description
Technical Field
[0001] This utility model belongs to the field of refrigerated vehicle technology and relates to a new energy commercial refrigerated vehicle box. Background Technology
[0002] Currently, when converting new energy vehicles such as Chery Jiangtun and Foton EV into refrigerated trucks, the interior cavity of the refrigerated truck body is sealed with insulation materials (usually polyurethane boards, polystyrene XPS boards, MPP boards, etc.) as the insulation layer. To meet the insulation standards for refrigerated truck bodies, these boards have a certain thickness, and a tailgate wall is usually added inside the original tailgate. This results in a smaller internal volume of the refrigerated truck body, reducing the load capacity for each trip and increasing the per-item, per-trip transportation cost, thus increasing the cost of transported goods, reducing competitiveness, and causing dissatisfaction among customers and users. At the same time, the original middle door is sealed off, preventing goods from entering or exiting through it, which is inconvenient. Furthermore, the switch for controlling the roof light of the refrigerated truck is located in the cab, and there are frequent situations where the tailgate is open but the roof light is not turned on, requiring the driver to return to the cab to turn it on, which is inconvenient. Utility Model Content
[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a user-friendly new energy commercial refrigerated truck box.
[0004] The objective of this utility model can be achieved through the following technical solutions:

[0006] The switch for controlling the lighting is located on the inner wall of the insulated cavity near the rear door. If you need to turn on the lighting after opening the rear door, simply press the switch. This is convenient and saves time that would otherwise be spent running back to the cab to turn on the switch. At the same time, the status of the lighting can be observed when closing the rear door, so that it can be turned off in time, avoiding the situation where you forget to turn off the lights after returning to the cab after closing the rear door, which can effectively save energy.
[0007] In the aforementioned new energy commercial refrigerated truck box, the side of the box body is provided with an openable middle door, and a second sealing structure is provided between the middle door and the box body.
[0008] The presence of a central door allows for loading and unloading of goods, significantly improving convenience.
[0009] In the aforementioned new energy commercial refrigerated truck body, the front of the insulated inner cavity is provided with an insulated front panel, the bottom of the insulated inner cavity is provided with an insulated floor, the lower end of the insulated front panel is sealed to the insulated floor, the left and right sides and the top of the insulated inner cavity are respectively provided with insulation layers, the insulation layers are respectively sealed to the insulated front panel and the insulated floor, the rear door and the middle door are respectively provided with insulation panels, and the insulated front panel, the insulated floor, the insulation layers and the insulation panels are respectively covered with conformal skins.
[0010] In order to save costs, the surface of the insulated floor may not be covered with thermoplastic skin unless the customer has special requirements.
[0011] The insulation layers on the left and right sides and the top, as well as the insulation front panel, are fixed to the vehicle body wall by applying structural adhesive and using automatic screws or rivets. After they are firmly fixed, the conformal skin is then glued to the inner surface of the insulation layer and the insulation front panel with structural adhesive. The structure formed from the inside out consists of the skin, the heat insulation material layer, and the vehicle body wall.
[0012] The insulation panels are fixed to the original vehicle's middle and rear doors with bolts or rivets, and corresponding structures are set according to the shape, locking position, handle position, and moving position of the middle and rear doors. The skin on the insulation panels is connected by structural adhesive.
