[0001] This utility model relates to the field of vehicle body technology, and in particular to a vehicle body structure for a four-wheeled cargo vehicle. Background Technology

[0002] Four-wheeled cargo vehicles are common means of transportation for carrying goods and people. They typically have a cargo box structure on top of the frame, which is used to carry people or goods.

[0003] Existing four-wheeled cargo truck bodies typically come in two forms: one with seats for convenient passenger transport, and the other without seats to accommodate more cargo. However, both types of cargo bodies have their drawbacks. Seats take up interior space, affecting cargo capacity, while the lack of seats makes it less comfortable for passengers to sit directly in the cargo box.

[0004] To solve the above-mentioned technical problems, this application provides a cargo box structure for a four-wheeled cargo vehicle. Utility Model Content

[0005] Based on the above situation, the main purpose of this utility model is to provide a cargo box structure for a four-wheeled cargo vehicle, so as to solve the problem that the existing four-wheeled vehicle cargo boxes are difficult to balance the comfort when carrying passengers and the cargo capacity when carrying goods.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cargo compartment structure for a four-wheeled vehicle, comprising a cargo box;

[0008] The compartment is provided with a cargo cavity, and two limiting strips are fixed inside the cargo cavity. Both limiting strips are located on the upper surface of the cargo cavity and are distributed on both sides of the cargo cavity.

[0009] A seat is provided on one side of the compartment. One side of the seat is hinged to the compartment. The seat can rotate to a horizontal or vertical position. When rotated to a horizontal position, the lower side of the seat can abut against the upper surface of the limiting strip.

[0010] Preferably, the body includes a bottom plate, side plates, a rear plate, and a front plate. There are two side plates, which are arranged opposite to each other. The front plate and the rear plate are arranged opposite to each other and are adjacent to the side plates.

[0011] The two limiting strips are respectively fixed to the upper side of the side plate, and the two limiting strips are fixed between the front plate and the rear plate.

[0012] Preferably, a vertical frame is fixed to the upper side of the front panel, the vertical frame is vertically arranged, and when the seat is rotated to the vertical position, the vertical frame and the seat are on the same plane.

[0026] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] Reference Figure 1-2 This utility model provides a cargo box structure for a four-wheeled cargo vehicle, installed on top of a frame, for carrying goods or passengers. It includes a cargo box 1 with a cargo cavity 2, wherein the cargo box 1 includes a floor plate 13, side plates 14, a front plate 11, and a rear plate 12. The floor plate 13, side plates 14, front plate 11, and rear plate 12 surround and form the cargo box structure with the cargo cavity 2.

[0028] Specifically, the two side panels 14 are arranged opposite each other, the front panel 11 and the rear panel 12 are arranged opposite each other, the bottom plate 13 is located below the carriage, the two side panels 14 are located on the left and right sides respectively, and the front panel 11 and the rear panel 12 are located at the front and rear ends of the carriage. It should be noted that, in order to leave space for the installation of wheels, the surface of the bottom plate 13 and the side panels 14 are provided with notches to avoid the wheel installation area; in addition, the rear panel 12 has an opening in the middle for installing a rotating door. These are all things that those skilled in the art can know, and the specific selection of the location of the notches and openings, as well as the structure of the rotating door and wheel installation area, will not be described in detail in this application.

[0029] The cargo compartment 2 of the carriage is equipped with two limiting strips 15. The two limiting strips 15 are fixed to the upper side of the side plate 14 respectively, so that the limiting strips 15 can be located on both sides above the cargo compartment 2, leaving a sufficiently large cargo space.

[0030] A vertical frame 111 is fixed to the upper part of the front panel 11. The plane on which the vertical frame 111 is located is vertically arranged. A seat 16 is arranged above the body 1. The seat 16 is hinged to the body 1 and can rotate and fold within the body 1. Specifically, the overall shape of the seat 16 is flat, and one side of the seat 16 is hinged to the front panel 11. The seat 16 can rotate to either a horizontal or vertical working state. When the seat 16 is rotated to the horizontal state, the lower side of the seat 16 can abut against the upper surface of the limiting strip 15. At this time, the seat 16 and the limiting strip 15 cooperate with each other to support the seat 16, so that the seat 16 can be stably positioned in a horizontal state, providing a comfortable seating position for passengers and facilitating passenger transport. When passengers are not needed and more cargo space is required, the seat 16 is rotated to an upright position. At this time, the seat 16 is close to the upright frame, and the upright frame and the seat 16 are on the same plane, which reduces the space occupied by the seat 16 in the interior of the carriage, allowing the carriage to accommodate more goods and effectively improving the cargo carrying capacity of the carriage.

[0031] As one embodiment, a hinge 161 is provided between the front panel 11 and the seat 16. The two flaps of the hinge 161 are fixed to the front panel 11 and the seat 16 respectively. The connection by the hinge can improve the stability of the seat 16 rotation.

[0032] Furthermore, a torsion spring (not shown in the figure) is provided on the pivot of the hinge 161. Under normal conditions, the torsion spring can drive the seat 16 to rotate from a horizontal state to a vertical state. When the seat 16 rotates to a vertical state, the torsion spring can provide a certain elastic force to keep the seat 16 in that state. When the seat 16 rotates to a horizontal state, the seat 16 can be fixed by a person sitting down and relying on their weight.

[0033] Furthermore, the method of fixing the position of the seat 16 is not limited to using a torsion spring. During use, the hinge 161 can also rotate freely without a torsion spring. In the horizontal position, the seat is limited by the limit strip 15, and the user's weight helps to control the swaying of the seat 16. In the vertical position, holes can be drilled on the side edge of the seat 16 and on the upright frame, and a wire can be tightened between the two holes for fixation. Although this method is not very secure, it is cheaper in practical applications. It should also be noted that the method of fixing the seat 16 is not limited to the above; it can also be fixed using latches, pins, or other methods that achieve the desired fixation.

[0034] As one embodiment, the carriage body 1 also includes a base frame 17, which is fixed to the lower side of the bottom plate 13. The base frame 17 includes multiple crossbeams 171 and longitudinal beams 172. There are two longitudinal beams 172, which are arranged in parallel. Multiple crossbeams 171 are fixed between the longitudinal beams 172. A support frame 173 is also fixed on the side of the longitudinal beam 172 away from the crossbeams 171. The support frame 173 is located at the end of the longitudinal beam 172 and is composed of square tubing welded together, which can stably support the bottom plate 13.

[0035] Multiple lifting lugs are fixed to the longitudinal beam 172 for securing it to the frame, thus stably fixing the carriage to the frame. This structure eliminates the need for the traditional direct contact between the floor plate 13 and the frame. The load-bearing system first connects the floor plate 13 to the underframe 17, then the underframe 17 contacts the frame, and multiple lifting lugs ensure a tight, stable, and wobbly fit for the carriage.

[0036] The implementation principle of this utility model is as follows: In actual use, when the four-wheeled cargo vehicle needs to carry passengers, the seat 16 is rotated to a horizontal position, with the lower side of the seat 16 abutting against the upper surface of the limiting strip 15, allowing passengers to sit on the seat 16. At this time, the interior space of the vehicle compartment meets the needs of passenger seating while still retaining a certain amount of cargo space. When the four-wheeled cargo vehicle needs to carry cargo, the seat 16 is rotated to a vertical position, with the seat 16 leaning against the vertical frame. The vertical frame and the seat 16 are on the same plane, reducing the space occupied by the seat 16 in the interior space of the vehicle compartment, allowing the compartment to accommodate more goods and effectively improving the cargo carrying capacity of the vehicle compartment.

[0037] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0038] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
