Description

Technical Field

[0001] This utility model relates to a closed cargo box for a pure electric bus, which belongs to the field of new energy closed van trucks. Background Technology

[0002] New energy light trucks have become the preferred model for urban distribution in recent years. However, the adjustment of standards and regulations for new energy light trucks has restricted the specifications of cargo boxes and tires. The cargo box width requirement for new energy light trucks is ≤2100mm.

[0003] The current loading status of new energy light truck vans is as follows: (1) The internal dimensions of the cargo box are 4200mm x 2100mm, and the standard pallet dimensions are 1200mm x 1000mm. It can hold 6 standard pallets.

[0004] (2) The internal dimensions of the cargo box are 4200mm x 2100mm, and the dimensions of the non-standard pallet are 1100mm x 1000mm. It can hold 6 non-standard pallets.

[0005] To increase the load-bearing capacity of the cargo box, existing passenger van / cargo van designs, even after converting the passenger area into a cargo area, still suffer from limited interior width due to the presence of interior panels. Furthermore, the fixed standard pallet size further restricts the number of light trucks that can be loaded.

[0006] Therefore, it is indeed necessary to improve existing technologies to address their shortcomings. Summary of the Invention

[0007] This utility model provides a closed cargo box for pure electric buses to solve the problems existing in the prior art. It increases the internal width of the cargo box by converting a bus into a freight car, thereby increasing the number of pallets.

[0008] The technical solution adopted by this utility model is as follows: a closed cargo box for a pure electric bus, including a body and a chassis connected to the body. The body includes a driving area, a cargo storage area, and a middle partition separating the driving area and the cargo storage area. The frame of the body includes longitudinal beams, vertical beams, horizontal beams, a first rectangular tube, and a top frame of the driver's cab. The frame of the driving area is formed by welding the top frame of the driver's cab and the horizontal beam located on the front side through the first rectangular tube. The frame of the cargo storage area is formed by welding longitudinal beams, vertical beams, and the horizontal beam located on the rear side. The cargo storage area also includes an upper top plate, a left side plate, a right side plate, a rear panel, and a lower bottom plate connected to the frame of the cargo storage area. The intermediate partition plate is composed of a high-strength galvanized sheet, a second rectangular tube, polyurethane foam, a plastic-coated connecting bracket, and an aluminum alloy plate. The high-strength galvanized sheet and the second aluminum alloy plate are arranged alternately. The plastic-coated connecting bracket includes several units, which are located between the high-strength galvanized sheet and the second aluminum alloy plate and are arranged alternately.

[0009] Furthermore, the vehicle body is a monolithic frame structure.

[0010] Furthermore, the outer layer of the top plate, left side plate, right side plate and rear panel are all cold-rolled stamped steel plates, the inner layer is a first aluminum alloy plate, and the middle filler is extruded board.

[0011] Furthermore, the bottom plate is made of bamboo plywood.

[0012] Furthermore, the second rectangular tube is located between any two adjacent plastic-coated connecting brackets and is in close contact with the high-strength galvanized sheet, and the rectangular tube is welded together with the plastic-coated connecting bracket.

[0013] Furthermore, the plastic-coated connecting bracket is coated with a rubber polymer material.

[0014] Furthermore, the plastic-coated connecting bracket is connected to the aluminum alloy plate by riveting.

[0015] Furthermore, the high-strength galvanized sheet is connected to the second rectangular tube by riveting.

[0016] This utility model has the following beneficial effects: (1) By converting passenger cars into freight cars, the inner width of the cargo box is increased, thereby increasing the number of pallets.

[0017] (2) Significantly improve logistics and transportation efficiency and increase transportation revenue for end users.

[0018] (3) Make full use of the overhead space of the cab to increase the driver's rest area and storage space. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] This utility model relates to a closed cargo box for a pure electric bus, comprising a body 1 and a chassis 2 connected to the body 1. The body 1 is an integral frame structure, and the skin covers the integral frame structure, enclosing the frame structure.

[0026] The vehicle body 1 includes a driving area 3, a cargo storage area 4, and a partition 5 that separates the driving area 3 and the cargo storage area 4.

[0027] The frame of the vehicle body 1 includes longitudinal beams 15, vertical beams 16, cross beams 17, a first rectangular tube 18, and a cab roof frame 19. The frame of the driving area 3 is formed by welding the cab roof frame 19 and the front cross beam 17 together through the first rectangular tube 18. The frame of the cargo storage area 4 is formed by welding the longitudinal beams 15, vertical beams 16, and the rear cross beam 17 together.

[0028] The cargo storage area 4 also includes an upper roof panel, left side panel, right side panel, rear panel, and lower floor panel connected to the frame of the cargo storage area 4. The outer layer of the upper roof panel, left side panel, right side panel, and rear panel is made of cold-rolled stamped steel sheet 7, the inner layer is made of first aluminum alloy sheet 6, and the middle filling material is extruded polystyrene board 8, which takes into account both heat preservation and the strength of the carriage. The lower floor panel is made of bamboo plywood, which is used for waterproofing and moisture resistance and also takes into account weight reduction.

[0029] The intermediate partition plate 5 is composed of a high-strength galvanized sheet 9, a second rectangular tube 10, polyurethane foam 11, a plastic-coated connecting bracket 12, and a second aluminum alloy plate 14. The high-strength galvanized sheet 9 and the second aluminum alloy plate 14 are arranged alternately. Several plastic-coated connecting brackets 12 are located between the high-strength galvanized sheet 9 and the aluminum alloy plate 14, also arranged alternately. The second rectangular tube 10 is located between any two adjacent plastic-coated connecting brackets 12 and is tightly attached to the high-strength galvanized sheet 9. The second rectangular tube 10 and the plastic-coated connecting bracket 12 are welded together. The plastic-coated connecting bracket 12 is coated with a rubber polymer material 13. The plastic-coated connecting bracket 12 is connected to the second aluminum alloy plate 14 by riveting, and the high-strength galvanized sheet 9 is connected to the second rectangular tube 10 by riveting.

[0030] This utility model relates to a closed cargo compartment for pure electric buses. By keeping the outer width of the cargo storage area consistent with that of the driver's area, and by modifying the main frame and side panels of the cargo storage area, the driver's area and the cargo storage area are isolated, and the width of the cargo area is greater than 2100mm, thereby increasing the number of pallets.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
