Description

Technical Field

[0001] This utility model relates to the field of truck technology, and in particular to the structure of an all-aluminum metal side-flipping truck cover. Background Technology

[0002] With the accelerated urbanization and continuous expansion of urban construction in my country, dump trucks, as a common type of specialized vehicle used in municipal engineering, construction engineering, and sanitation, have experienced rapid development in recent years. Furthermore, with the increasing awareness of environmental protection and the strengthening of environmental regulations, the environmental performance requirements for dump trucks are becoming increasingly stringent, and the demand for lightweight dump trucks is also growing. Currently, the side-tipping roofs of dump truck cargo boxes are mostly made of welded steel pipes and steel skin, resulting in heavy weight, numerous parts, and poor rigidity at the area below the skin where there is no frame, making them prone to deformation after cargo collisions.

[0003] The existing technology, application number: CN2019207156593, is a single-sided flip-top anti-theft box. Its structure is processed as a whole, which makes it heavy. The steel top cover is connected by several hinges to achieve the flip. Over time, the welds are prone to failure, which poses a great safety hazard.

[0004] Therefore, it is necessary to design a structure for an all-aluminum metal side-flipping hatch cover to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a structure for an all-aluminum metal side-flipping hatch cover to overcome the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A structure for an all-aluminum side-flipping cargo box includes two sets of top cover plates and side plates respectively disposed on the outer side of the top cover plates for connection with the cargo box body. The top cover plate is characterized by: a main plate formed by sequentially splicing several sets of cover plate profiles from left to right; side connecting plate profiles disposed on both sides of the main plate for connection with the side plates; and a flipping mechanism mounting bracket disposed on the main plate. Several sets of evenly spaced connecting blocks are provided on the side of the side connecting plate profiles not connected to the cover plate profiles. Through holes are formed on the connecting blocks, and the through holes of each set of connecting blocks are all centered on the same axis. Several sets of evenly spaced auxiliary connecting blocks are also provided on the side of the side plate that connects to the side connecting plate profiles. The auxiliary connecting blocks are staggered with the main connecting blocks and are interlocked. Through grooves are formed on the auxiliary connecting blocks, and the through grooves on the auxiliary connecting blocks and the main connecting blocks are centered on the same axis. Rotating shafts are inserted into the through grooves of the main connecting blocks and auxiliary connecting blocks.

[0008] Preferably, the cover plate profiles are spliced ​​and assembled by friction stir welding, and the side connecting profiles are also connected to the cover plate profiles by friction stir welding. Furthermore, the inner cavities of the cover plate profiles and the side connecting plate profiles are provided with square structural skeletons.

[0009] Preferably, the length of the side connecting plate profile is less than the length of the cover plate profile.

[0010] Preferably, the flipping mechanism mounting bracket includes a mounting plate disposed on the upper surface of the side connecting plate profile, a nut plate disposed on the lower surface of the side connecting plate profile, a threaded sleeve disposed through the upper surface and the side connecting plate profile, and a bolt that mates with the threaded sleeve.

[0011] The beneficial effects of this utility model are: This technical solution uses all-aluminum profiles to integrate the panel and frame profiles, which increases the space for cargo transfer and improves transportation efficiency. Moreover, the cover plate is an integrated structure to ensure the rigidity of the top cover. The process is simple, the number of parts is small, and the cost is low. Compared with traditional steel structures, the weight reduction can be significantly up to 50%, and the lightweight advantage is significant. Attached Figure Description

[0018] Reference Figures 1 to 5A structure of an all-aluminum metal side-flipping box cover includes two sets of top cover plates 1 and side plates 2 respectively disposed on the outside of the top cover plates and used to connect with the box body; the other sides of the two sets of top cover plates 1 are disposed corresponding to each other and used to cooperate in opening and closing.

[0019] The top cover 1 is a main board composed of several sets of cover plate profiles 11 spliced ​​together from left to right, side connecting plate profiles 12 arranged on both sides of the main board and used to connect with the side plates, and a flip mechanism mounting bracket 3 arranged on the main board.

[0020] The cover plate profiles are assembled by friction stir welding, and the side connecting profiles are also connected to the cover plate profiles by friction stir welding. The inner cavities of the cover plate profiles and the side connecting plate profiles 12 are provided with square structural skeletons 111 to ensure the lightweight of the entire cover plate profile, reduce the weight of the material, and increase the load-bearing capacity of the cover plate profile, thereby increasing the strength of the entire mechanism. The overall structure is made of aluminum.

[0021] To facilitate installation on the truck, the length of the side connecting plate profile 12 is shorter than the length of the cover plate profile. The shorter part of the side connecting plate profile 12 is used to avoid the installation of truck parts. On the side of the side connecting plate profile 12 that is not connected to the cover plate profile, there are several sets of evenly spaced connecting blocks 121. Through holes are opened on the connecting blocks, and the through holes of each set of connecting blocks are all located on the same axis.

[0022] The side of the side plate 2 that connects with the side connecting plate profile is also provided with several sets of auxiliary connecting blocks 21 that are evenly spaced.

[0023] The auxiliary connecting blocks are staggered with the connecting blocks and are interlocked. A through groove is formed on the auxiliary connecting block, and the through groove on the auxiliary connecting block and the connecting block are aligned on the same axis. A rotating shaft 4 is inserted into the through grooves of the connecting block and the auxiliary connecting block. The rotating shaft connects the auxiliary connecting block and the connecting block, and connects the side plate and the side connecting plate profile. Inserting the entire rotating shaft between the profiles ensures the connection strength between the large and small cover plates.

[0024] The flipping mechanism mounting bracket 3 is used to strengthen the top cover plate. During the side flipping process, the material at the top of the flipped top cover plate is subjected to a large force, making it the main stress point. Therefore, it is prone to damage after long-term use, thus reducing its service life. The special structure of the flipping mechanism mounting bracket 3 strengthens the plate and improves the stress resistance. The flipping mechanism mounting bracket 3 includes a mounting plate 31 set on the upper surface of the side connecting plate profile 12, a nut plate 32 set on the lower surface of the side connecting plate profile, a threaded sleeve 33 penetrating the upper surface and the side connecting plate profile 12, and a bolt 34 that mates with the threaded sleeve. The specific assembly steps are as follows: A steel threaded sleeve 43 is welded to the upper nut plate 42 of the flipping mechanism mounting bracket 4. After welding, it is inserted into the profile. Then, the lower mounting plate is screwed to the threaded sleeve 43. This method uses double-layer steel plates to screw to the profile, avoiding stress on a single-layer panel, reducing the risk of hinge failure over time, and extending the service life of the top cover.

[0025] The advantages of this utility model are that the technical solution uses all-aluminum profiles to integrate the panel and frame profiles, which increases the space for cargo transfer and improves transportation efficiency. In addition, the cover plate is an integrated structure to ensure the rigidity of the top cover. The process is simple, the number of parts is small, and the cost is low.

[0026] 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.
