Description

Technical Field

[0001] This utility model relates to the field of truck technology, and in particular to a lightweight U-shaped cargo box structure that combines steel and aluminum. Background Technology

[0002] With the rapid development of urban infrastructure, dump trucks play an indispensable role in urban infrastructure construction. At the same time, in order to address environmental challenges and control air pollution, cities are requiring the transportation of construction waste to develop in a green, environmentally friendly, and intelligent direction.

[0003] Currently, most dump truck cargo boxes are made of steel. Although the use of high-strength steel in recent years has improved the lightweighting of cargo boxes to some extent, the thickness of the steel plate cannot be too thin in order to adapt to the harsh working conditions of dump trucks. In addition, the high density of steel itself has made the lightweighting effect of the cargo box less than ideal. If an all-aluminum cargo box is designed, the characteristics of aluminum, such as its poor wear resistance and low elastic modulus, cannot meet the safety, wear resistance, and dent resistance requirements of dump trucks.

[0004] The existing technology, application number: 2021111859748, is a lightweight light truck cargo box. Its structural frame profile is connected by bolts, and its material is not wear-resistant and has limited strength.

[0005] Therefore, a lightweight U-shaped cargo box structure made of steel and aluminum needs to be designed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a lightweight U-shaped cargo box structure that combines steel and aluminum to overcome the aforementioned shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lightweight U-shaped cargo box structure made of steel and aluminum composite includes a U-shaped base, side plates on both sides of the U-shaped base, a front plate at the front end of the base, and a rearward plate at the rear end. The U-shaped base, side plates, front plate, and rearward plate are fixedly connected by locking parts to form the cargo box. The U-shaped base includes several sets of frame profiles, corner profiles for connecting the frame profiles and positioned at the bending angles, and inner wear-resistant steel plates attached to the outer surfaces of the frame profiles and corner profiles. The frame profiles include a square frame, reinforcing ribs within the square frame, a concave structure at one end of the square frame, and a convex structure at the other end of the square frame. The reinforcing ribs are triangular and sequentially arranged within the square frame. The corner profiles have a first concave structure at one end and a first convex structure at the other end, and several sets of triangular reinforcing ribs on the corner profiles.

[0009] Preferably, the skeleton profiles are connected end to end, with the concave structure and the convex structure interlocked and installed together by friction stir welding.

[0010] Preferably, the first concave structure and the convex structure of the skeleton profile are interlocked, and the first convex structure and the concave structure of the skeleton profile are interlocked, and the connection and fixation are achieved by friction stir welding at the interlocking point.

[0011] Preferably, the inner wear-resistant steel plate is bonded to the outer surface of the frame profile and the outer surface of the corner profile by an adhesive, and the inner wear-resistant steel plate is installed with the frame profile or corner profile by riveting.

[0012] The beneficial effects of this utility model are: This technical solution uses clear and bright frame profiles and corner profiles to quickly assemble and weld, forming a cargo box structure. The structure is lightweight and easy to assemble. Compared with existing steel boxes of the same performance, it reduces weight by about 40%, showing obvious advantages in lightweighting. It can reduce the weight of the cargo box and improve the carrying capacity and range of the dump truck. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Reference Figures 1 to 3 A lightweight U-shaped cargo box structure made of steel and aluminum composite includes a U-shaped base 1, side plates 2 on both sides of the U-shaped base, a front plate 3 at the front end of the U-shaped base, and a rearward plate 4 at the rear end of the U-shaped base. The U-shaped base, side plates, front plate, and rearward plate are fixedly connected by locking parts to form the cargo box. The U-shaped base facilitates the effective unloading of construction goods and is easy to clean, reducing pollution to the road surface.

[0020] The side panels, front panel, and rear panel of the cargo box are designed to accommodate different requirements for the roof in various cities (side-flipping or sliding sealed roof). The cargo box side panels are compatible with various roof requirements; only the upper end panel needs to be changed to meet different roof requirements, resulting in low investment costs and convenient switching.

[0021] The U-shaped base 1 of the cargo box includes several sets of frame profiles 11, corner profiles 12 for connecting the frame profiles and placed at the bending angle, and inner wear-resistant steel plates 13 attached to the outer surfaces of the frame profiles and corner profiles.

[0022] The skeleton profile 11 includes a square frame 111, a reinforcing rib 112 placed inside the square frame, a concave structure 113 at one end of the square frame, and a convex structure 114 at the other end of the square frame.

[0023] The frame profiles 11 are connected end to end, and the concave structure 113 and the convex structure 114 are embedded and installed together. They are also installed together by friction stir welding to form a base plate and a side plate. The base plate and the side plate are then connected by the transfer profile 12 to form a U-shaped base. This facilitates the effective unloading of construction goods and makes it easy to clean, reducing pollution to the road surface.

[0024] The reinforcing ribs are triangular in shape and are arranged sequentially within the square frame. The triangular shape of the reinforcing ribs can maximize the overall strength, thereby ensuring the strength of the entire profile, saving materials, and reducing weight.

[0025] The corner profile 12 has a first concave structure 121 at one end and a first convex structure 122 at the other end, and a number of triangular reinforcing ribs are provided on the corner profile 12. The first concave structure is interlocked with the convex structure of the frame profile, and the first convex structure 122 is interlocked with the concave structure of the frame profile. At the same time, the interlocking parts are connected and fixed by friction stir welding. The insertion area and weld of the profile connection part are stressed simultaneously. In addition, the friction stir welding process has low heat loss and high overall rigidity.

[0026] The inner wear-resistant steel plate 13 is bonded to the outer surface of the frame profile 11 and the outer surface of the corner profile 12 by adhesive. The inner wear-resistant steel plate 13 is installed with the frame profile 11 or the corner profile 12 by riveting. The two methods are used to reinforce the installation at the same time. The use of the inner high-strength wear-resistant plate can avoid the wear of the aluminum profile by construction waste, increase the impact resistance of the cargo box, meet the performance and wear resistance requirements of the dump truck cargo box, and allow the inner steel plate and the outer frame to bear the force as a whole.

[0027] The advantages of this utility model are that, by setting up clear and bright frame profiles and corner profiles, the cargo box structure can be quickly assembled and welded to form a cargo box structure. The structure is lightweight and easy to assemble. Compared with existing steel boxes of the same performance, it reduces the weight by about 40%, and the lightweight advantage is obvious. It can reduce the weight of the cargo box and improve the carrying capacity and range of the dump truck.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
