[0002] According to relevant national policies, overloading needs to be addressed with great effort. In conjunction with the implementation of the weight-based toll system, controlling the total weight of vehicles is an urgent issue that needs to be resolved. In addition, considering the energy conservation, environmental protection and safety of vehicles, the lightweighting of commercial vehicles has become an inevitable trend.

[0003] Traditional truck bodies are made of cold-rolled steel plates, with many welded parts. The steel bodies themselves are quite heavy, and workers cannot install them quickly. Furthermore, the weight of the bodies makes it impossible to meet the requirements for lightweight truck bodies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-assembly lightweight truck body to solve the problems mentioned in the background art, such as the traditional truck body being made of cold-rolled steel plate, having many welded parts, and being heavy, making it difficult for workers to install the body quickly, and failing to meet the requirements for lightweight truck bodies due to their heavy weight.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly lightweight truck body, comprising a truck body main body, a truck body floor plate at the bottom of the truck body main body, truck body side plates at both ends of the truck body main body, two first slots on the truck body floor plate with opposite openings, a first locking block fixedly installed at the bottom of each of the truck body side plates, a second slot on the front end surface of each of the truck body side plates, a truck body door frame at the front end of the truck body main body, a second locking block fixedly installed on the rear end surface of the truck body door frame, and a truck body door rotatably mounted on the front end surface of the truck body door frame.

[0006] By adopting the above technical solution, the first clips installed at the bottom of the two side panels of the carriage are inserted into the first slots opened on the bottom plate of the carriage. Then, the workers insert the second clip installed at the rear end of the door frame into the second slot opened at the front end of the side panel of the carriage, thereby installing the door frame. Since the openings of the first slots are set in opposite directions, the main body of the carriage can have a high degree of stability after installation.

[0007] Preferably, the rear end surface of the side panels of the carriage is provided with mounting grooves, and the mounting grooves are provided with positioning holes. The floor of the carriage is provided with slots near the rear end.

[0008] Using the above technical solution, the mounting plate can be installed in the mounting groove opened at the rear end of the side panel of the carriage, so that the positioning rod can be inserted into the positioning hole therein, and then the insert block at the bottom of the rear panel can be inserted into the slot, thereby fixing the rear panel.

[0009] Preferably, a rear panel is provided at the rear end of the main body of the carriage, and mounting plates are installed opposite each other on the inner surface of the rear panel. Positioning rods are fixedly installed at the bottom of the mounting plates, and inserts are fixedly installed at the bottom of the rear panel. Mounting holes are provided at the rear ends of both the inserts and the carriage floor.

[0010] Using the above technical solution, the mounting plate on the rear panel is aligned with the mounting groove opened on the side panel of the vehicle body, and then the positioning rod at the bottom of the mounting plate is inserted into the positioning hole in the mounting groove. At the same time, the insert is inserted into the slot on the floor of the vehicle body, thereby fixing the side panel and the rear panel of the vehicle body. Then, bolts are used to pass through the mounting holes to keep the rear panel stable with the side panel and the floor of the vehicle body.

[0011] Preferably, a roof plate is provided at the top of the main body of the carriage, and a positioning frame is provided near the top of the main body of the carriage. Fixing holes are provided at all four ends of the positioning frame, and fixing bolts are inserted into the fixing holes.

[0012] Using the above technical solution, after the side panels, floor panels, door frames, and rear panels of the carriage are installed, the workers then install the roof panel onto the main body of the carriage, and then install the positioning frame onto the main body of the carriage. Finally, fixing bolts are inserted into the fixing holes on the positioning frame, so that the fixing holes penetrate the side panels, rear panels, and door frames of the carriage, thereby performing secondary fixing of the main body of the carriage.

[0013] Preferably, the side panels, rear panels, and roof panels of the carriage are all provided with honeycomb interlayers, the honeycomb interlayers are provided with glass fibers, and the glass fibers are provided with polypropylene sheets.

[0014] By adopting the above technical solution, the honeycomb interlayer set in the side panels, rear panels and roof panels of the carriage can effectively reduce the overall weight of the carriage body. Then, the glass fiber and polypropylene panels can effectively improve impact resistance and high temperature and oxidation resistance, thus effectively improving the overall strength of the carriage body.

[0015] Preferably, the first card slot, the first card block, the second card block, and the second card slot are all T-shaped.

[0016] By adopting the above technical solution, since the first card slot, the first card block, the second card block and the second card slot are all T-shaped, they can be fixed together in a better way.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This quick-assembly lightweight truck body is installed by inserting the first slot into the floor panel of the truck body, then inserting the second slot at the rear end of the door frame into the second slot at the front end of the side panel, and then aligning the mounting plate on the rear panel with the mounting groove on the side panel to insert the positioning rod into the positioning hole in the mounting groove. Simultaneously, the insert block is inserted into the slot on the floor panel. The top panel is then installed onto the main body of the truck body, and the positioning frame is installed onto the main body. Fixing bolts are then inserted into the fixing holes on the positioning frame, allowing the fixing holes to penetrate the side panel, rear panel, and door frame. This allows for rapid installation of the truck body, improving installation efficiency.

[0019] 2. This quick-assembly lightweight truck body effectively reduces the overall weight of the main body through the honeycomb sandwich panels in the side panels, rear panels, and roof panels. In conventional honeycomb sandwich panels, the volume of solid material is only 1%-3%, with the remaining space being sealed air. This provides a leading lightweight advantage, ensuring its strength under pressure while also making the main body of the truck body lighter. Furthermore, the use of fiberglass and polypropylene panels improves impact resistance and high-temperature and oxidation resistance, thus enhancing the overall strength of the main body of the truck body. The first slot, first block, second block, and second slot are all T-shaped, which facilitates their secure fixing. Attached Figure Description

[0027] Example 1:

[0028] Referring to Figures 1-5, a quick-assembly lightweight truck body is described. The bottom of the truck body 1 has a floor plate 2, and side panels 3 are provided on both sides of the truck body 1. The floor plate 2 has two first slots 4 with opposite openings. First blocks 5 are fixedly installed at the bottom of each side panel 3. Second slots 6 are provided on the front surface of each side panel 3. A door frame 7 is provided at the front of the truck body 1. Second blocks 8 are fixedly installed on the rear surface of the door frame 7. A truck door 9 is rotatably mounted on the front surface of the door frame 7. Mounting grooves 10 are provided on the rear surface of each side panel 3. The mounting slots 10 are provided with positioning holes 11. The floor plate 2 of the carriage is provided with a slot 12 near the rear end. The rear panel 13 of the carriage body 1 is provided at the rear end. The inner surface of the rear panel 13 is provided with mounting plates 14 facing each other. The bottom of the mounting plates 14 is fixedly installed with positioning rods 15. The bottom of the rear panel 13 is fixedly installed with inserts 16. The inserts 16 and the rear end of the floor plate 2 of the carriage body 1 are provided with mounting holes 17. The top of the carriage body 1 is provided with a carriage top plate 18. The top of the carriage body 1 is provided with a positioning frame 19. The four ends of the positioning frame 19 are provided with fixing holes 20. Fixing bolts 21 are inserted into the fixing holes 20.

[0029] Working principle: When the main body 1 of the carriage needs to be installed, the worker inserts the first locking blocks 5 installed at the bottom of the two carriage side panels 3 into the first locking slots 4 opened on the carriage floor 2. Then, the worker inserts the second locking block 8 installed at the rear end of the carriage door frame 7 into the second locking slot 6 opened at the front end of the carriage side panel 3, thereby installing the carriage door frame 7. Since the openings of the first locking slots 4 are set in opposite directions, this can better ensure the high stability of the main body 1 after installation. Then, the mounting plate 14 on the rear panel 13 is aligned with the mounting groove 10 opened on the carriage side panel 3. Then, the positioning rod 15 at the bottom of the mounting plate 14 is inserted into the positioning hole 11 in the mounting groove 10, and at the same time, the insert 16 is inserted into the carriage floor 2. The side panel 3 and the rear panel 13 are fixed in the slot 12. Then, bolts are used to pass through the mounting holes 17 to stabilize the rear panel 13 with the side panel 3 and the floor panel 2. After the side panel 3, the floor panel 2, the door frame 7 and the rear panel 13 are installed, the workers install the roof panel 18 onto the main body 1. Then, the positioning frame 19 is installed onto the main body 1. Then, the fixing bolts 21 are inserted into the fixing holes 20 on the positioning frame 19 to make the fixing holes 20 pass through the side panel 3, the rear panel 13 and the door frame 7, thereby stabilizing the main body 1. Therefore, this allows the workers to quickly install the main body 1, thereby improving the installation efficiency.

[0030] Example 2:

[0031] Referring to Figures 1-5, a quick-assembly lightweight truck body is provided, wherein the side panels 3, rear panels 13, and top panels 18 of the truck body are all provided with honeycomb sandwich layers 22, glass fibers 23 are provided on the honeycomb sandwich layers 22, and polypropylene boards 24 are provided on the glass fibers 23. The first slot 4, the first block 5, the second block 8, and the second slot 6 are all T-shaped.

[0032] Working principle: The honeycomb sandwich 22 set in the side panel 3, rear panel 13 and top panel 18 of the carriage can effectively reduce the overall weight of the carriage body 1. In the conventional honeycomb sandwich 22, the volume of solid material is only 1%-3%, and the rest of the space is sealed air. Therefore, it has a leading lightweight advantage. Moreover, each honeycomb sandwich 22 has countless fixed honeycomb structures that will not move. The dense honeycomb structure that is mutually restrained in the honeycomb sandwich 22 can distribute the pressure from all directions, ensuring its pressure resistance and also making the carriage body 1 lighter. The glass fiber 23 and polypropylene board 24 can improve the impact resistance and high temperature resistance and oxidation resistance, thus improving the overall strength of the carriage body 1. The first slot 4, the first block 5, the second block 8 and the second slot 6 are all T-shaped, which can effectively fix them together.
