[0002] Fire truck bodies are typically composed of multiple main panels that form the frame structure. Currently, these panels are usually connected by welding. However, this welded construction generates welding stress, which can lead to poor precision, poor corrosion resistance, and low structural strength. Furthermore, welding is inefficient. Additionally, the roller shutter door mechanism and tilting ramp mechanism, which are also welded to the frame structure, similarly generate welding stress, resulting in poor precision, corrosion resistance, and low structural strength. Moreover, these mechanisms occupy internal space within the frame, reducing its capacity. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Example Please refer to Figures 1-13This embodiment provides a fire truck body structure, including a body comprising multiple main panels 101. The main panels 101 are assembled to form a frame structure 1. The contact surface of adjacent main panels 101 is a 45° angled slope 3. Multiple connection holes 5 are provided on the slope 3 of each main panel 101. An L-shaped connector 4 connects two adjacent connection holes 5 on adjacent main panels 101. The two ends of the L-shaped connector 4 extend into the two adjacent connection holes 5, and are fixedly connected to their respective main panels 101 by bolts 6. The L-shaped connector 4 engages with the connection holes 5 on the main panels 101, allowing the two ends of the L-shaped connector 4 to be fixedly connected to their respective main panels 101 by bolts 6, enabling adjacent main panels 101 to be quickly and securely connected together. The contact surfaces of adjacent main panels 101 are 45° inclined surfaces 3. Therefore, when assembling two adjacent main panels 101, ensuring their inclined surfaces 3 fit together effectively guarantees assembly accuracy. Inserting L-shaped connectors 4 into the two corresponding main panels 101 also effectively enhances the strength of the entire box frame structure 1. Furthermore, compared to welding, this application uses L-shaped connectors 4 inserted into corresponding connection holes 5, and finally, bolts are used to fix the main panel 101 to the L-shaped connectors 4. This assembly method is very convenient and quick. Therefore, this fire truck box structure can be quickly and effectively connected without welding, ensuring assembly accuracy while effectively improving structural strength.

[0018] Preferably, a sealing element 7 is provided between the adjacent main plates 101. The sealing element 7 includes a base plate 702 and two sealing ends 701. A through hole 8 adapted to the sealing end 701 is formed on the inclined surface 3 of any main plate 101. The two sealing ends 701 are symmetrically arranged on both sides of the base plate 702, and the angle between any sealing end 701 and the base plate 702 is 45°. The two sealing ends 701 respectively extend into the through holes 8 of the two main plates 101. A through hole 9 matching the end of the L-shaped connector 4 is formed on the sealing end 701, and the end of the L-shaped connector 4 can pass through the through hole 9. The sealing end 701 of the sealing element 7 forms a 45° angle with the base plate 702, thus adaptably fitting the base plate 702 to the inclined surface 3 of the corresponding main plate 101, ensuring the sealing effect of the base plate 702. Simultaneously, it also facilitates the insertion of the two sealing ends 701 into the corresponding through holes 8 on the two adjacent main plates 101. These through holes 8 not only reduce the material used in the main plate 101 and save costs, but also allow the sealing end 701 to fit with its inner wall to form a stepped sealing structure, further improving the sealing effect.

[0019] Preferably, countersunk holes 10 are provided on any of the main plate 101, and bolt holes 11 corresponding to the countersunk holes 10 are provided on the L-shaped connector 4. Bolts 6 pass through the countersunk holes 10 and bolt holes 11 in sequence, thus fixing the main plate 101 and the L-shaped connector 4 together. By providing countersunk holes 10 and corresponding bolt holes 11, and using bolts 6 to fix the main plate 101 and the L-shaped connector 4 together, this connection method not only ensures structural stability but also effectively avoids exposed connecting parts, improving the aesthetics and safety of the entire fire truck body structure. At the same time, the design of the countersunk holes 10 makes the connection smoother, reducing potential scratches or damage caused by protruding connecting parts. Furthermore, this connection method facilitates disassembly and maintenance, improving ease of use.

[0020] Furthermore, in this embodiment, multiple parallel connecting grooves 12 are formed on any of the main body panels 101. The cross-section of each connecting groove 12 is a dovetail groove structure, and a dovetail connecting block 13 is disposed within the connecting groove 12. The dovetail groove structure of the connecting groove 12 can restrict the dovetail connecting block 13 that mates with it, so that the dovetail connecting block 13 can be confined within the connecting groove 12. The dovetail connecting block 13 can serve as an installation module for connecting other functional components such as the roller shutter door mechanism and the flip-up pedal mechanism 18. In addition, this connecting groove 12 with a dovetail groove structure can further reduce the material consumption of the main body panel 101, while ensuring the strength of the main body panel 101 after grooving.

[0021] In some embodiments of this example, a roller shutter door mechanism is also included. A doorway 17 is provided on the box frame structure 1, and the roller shutter door mechanism is located on the side of the doorway 17. The roller shutter door mechanism includes a box-type roller shutter door body 14 located outside the box frame structure 1 and two guide rails 15 located outside the box frame structure 1. The two guide rails 15 are arranged parallel and symmetrically on both sides of the box frame structure 1, and each guide rail 15 is provided with a mating surface 16. The mating surface 16 of any guide rail 15 can be engaged with the corresponding main plate 101 on both sides of the box frame structure 1. The box-type roller shutter door body 14 is disposed on the guide rail 15, and the box-type roller shutter door body 14 is connected to the dovetail-shaped connecting block 13 on the corresponding main plate 101 on the top side of the box frame structure 1.

[0022] In this embodiment, the aforementioned roller shutter door mechanism is used to open and close the doorway 17. The box-type roller shutter door body 14 and guide rails 15 cooperate with the main plate 101 to install the box-type roller shutter door outside the box frame structure 1. This achieves 100% space utilization of the box frame structure 1. The roller shutter door size is larger than the maximum size of the box frame structure 1, which not only maximizes the space utilization of the box frame structure 1 but also facilitates the removal of equipment. Since the box-type roller shutter door body 14 is connected to the dovetail-shaped connecting block 13 on the corresponding main plate 101 on the top side of the box frame structure 1, the connection firmness is improved. This connection method also has the advantages of being stable and reliable, and can withstand a certain amount of external impact, ensuring the stability of the roller shutter door during use. At the same time, the mating surfaces 16 provided on the two guide rails 15 are engaged with the corresponding main plates 101 on both sides of the box frame structure 1. This engagement method is not only convenient to install but also ensures the connection accuracy and stability between the guide rails 15 and the box frame structure 1. The aforementioned guide rail 15 is snapped into the corresponding main plate 101, and at the same time, the box-type roller shutter door body 14 is connected to the dovetail connecting block 13 on the corresponding main plate 101 on the top side of the box frame structure 1. This can avoid various problems caused by traditional welding and effectively improve assembly efficiency.

[0023] In some embodiments of this example, a flip-up pedal mechanism 18 is also included, located outside the box frame structure 1. The flip-up pedal mechanism 18 is disposed on the bottom surface of the main plate 101 on the bottom side of the box frame structure 1. The aforementioned flip-up pedal mechanism 18 actually includes a hinge structure (not shown in the figure), which is connected to the bottom surface of the main plate 101 through the hinge, allowing for flexible flipping. When the pedal is needed, it is flipped downwards to a horizontal position, providing a stable standing or operating platform for personnel; when not in use, it is flipped upwards and folded up, close to the bottom surface of the main plate 101, without occupying extra space. This design not only facilitates the operation of firefighters when entering and exiting the box, but also ensures the compactness and safety of the box during movement.

[0024] It should be noted that the aforementioned flip-up pedal mechanism 18 is located outside the housing frame structure 1, maximizing the space utilization of the housing frame structure 1. The size of the flip-up pedal mechanism is also larger than the maximum size of the housing frame structure 1. This not only maximizes the space utilization of the housing frame structure 1 but also facilitates the removal of equipment.

[0025] In some embodiments of this utility model, the fixed end of the aforementioned flip-up pedal mechanism 18 is fixed to a dovetail-shaped connecting block 13 on the main plate 101 located at the bottom of the box frame structure 1. The dovetail-shaped connecting block 13 is used to connect the flip-up pedal mechanism 18 and the corresponding main plate 101, making the connection between the flip-up pedal mechanism 18 and the main plate 101 more stable and reliable, avoiding various problems caused by traditional welding connection methods, and effectively preventing the connection from loosening or falling off due to shaking or external force during use.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
