Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a support and fixing structure for the floor of a three-wheeled vehicle. Background Technology

[0002] Three-wheeled vehicles typically have a cargo box at the rear, which usually has a floor support structure. This floor support structure is a key component ensuring the load-bearing capacity and stability of the cargo box. Current technology primarily employs a frame-stabilized support structure. This structure usually consists of crossbeams and longitudinal beams, forming a frame to support the floor, with the crossbeams and longitudinal beams fixed together by welding.

[0003] The applicant has discovered at least the following technical problems in the existing technology: the floor of the existing tricycle box is usually only tightly connected to the crossbeams, while the longitudinal beams are suspended relative to the floor and are only connected to the crossbeams, not to the floor. However, tricycles are mainly used for heavy-duty driving. Under long-term heavy-duty driving, the welds may fall off or break due to stress and welding strength issues, leading to deformation and breakage of the welded pipes of the longitudinal beams. Utility Model Content

[0004] The purpose of this utility model is to provide a support and fixing structure for the floor of a three-wheeled vehicle to solve the technical problems existing in the prior art. The various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A three-wheeled vehicle cargo box floor support and fixing structure includes a floor body, crossbeams, and longitudinal beams. The top of the crossbeams is connected to the bottom of the floor body. Several crossbeams are arranged laterally and distributed longitudinally. Each longitudinal beam has a clearance structure at a corresponding position of each crossbeam. The longitudinal beams are arranged longitudinally and their tops are connected to the bottom of the floor body. At the same time, each crossbeam can be embedded in the corresponding clearance structure on the longitudinal beam and form a cooperative connection with the clearance structure.

[0006] Preferably, the avoidance structure is a slot, and the shape of the slot matches the cross-sectional shape of the beam.

[0007] Preferably, the crossbeam is a rectangular tube structure.

[0008] Preferably, the longitudinal beam is a rectangular tube structure, which includes a first top plate, a first bottom plate, and two first side plates. The first top plate is connected to the top of one of the first side plates at both ends in the horizontal direction, and the first bottom plate is connected to the bottom of one of the first side plates at both ends in the horizontal direction. The two first side plates are provided with the avoidance structure, and the first top plate is connected to the bottom plate body.

[0009] Preferably, the longitudinal beam is a sheet metal structure, which includes two second top plates, one second bottom plate, and two second side plates. The two ends of the second bottom plate are connected to the bottom of one of the second side plates in the horizontal direction. The top of each of the second side plates is connected to the inner end of one of the second top plates. The two second side plates are provided with the avoidance structure. Both second top plates are connected to the bottom plate body.

[0010] Preferably, the first top plate is welded to the bottom plate body.

[0011] Preferably, both second top plates are welded to the base plate body.

[0012] Preferably, it further includes side panels, with each of the four outer edges of the base plate body connected to the top of one of the side panels, each end of each crossbeam connected to a side panel parallel to the length direction of the longitudinal beam, and each end of each longitudinal beam connected to a side panel parallel to the length direction of the crossbeam.

[0013] The beneficial effects of this utility model are as follows: While keeping the crossbeam unchanged, the structure of the longitudinal beam in the three-wheeled vehicle floor support and fixing structure has been improved. By setting up an avoidance structure, the structure of the avoidance structure is exactly matched with the crossbeam. During assembly, the crossbeam can be embedded with the avoidance structure, so that the top of the longitudinal beam can be in complete contact with the bottom surface of the floor body. Without changing the structural strength of the crossbeam, the number of welding points and the fit of the longitudinal beam are increased. The contact area between the longitudinal beam and the floor body is greatly increased, the stress is more even, and the number of welding points between the longitudinal beam and the floor body and between the longitudinal beam and the crossbeam is also greatly increased, making the structure more robust.

[0014] The manufacturing process of the three-wheeled vehicle's floor support structure is simpler, allowing for better control over structural consistency, reducing production control difficulties, lowering costs, increasing strength, and making it more durable. Attached Figure Description

[0019] Reference Figures 1 to 4 This utility model provides a support and fixing structure for the floor of a three-wheeled vehicle, including a floor body 1, a crossbeam 2 and a longitudinal beam 3.

[0020] The top of the crossbeam 2 is connected to the bottom of the base plate 1. Several crossbeams 2 are arranged horizontally and distributed in sequence in the longitudinal direction. The specific number of crossbeams 2 is not limited and can be flexibly selected and set according to actual use needs. Furthermore, the spacing between two adjacent crossbeams 2 needs to be flexibly adjusted according to actual stress requirements.

[0021] The number of longitudinal beams 3 is at least one, and each longitudinal beam 3 is provided with a clearance structure 37 at the corresponding position of each crossbeam 2. Therefore, each longitudinal beam 3 can be connected with all the crossbeams 2.

[0022] The longitudinal beam 3 is arranged longitudinally and its top is connected to the bottom of the base plate body 1. At the same time, each crossbeam 2 can be embedded in the corresponding avoidance structure 37 on the longitudinal beam 3 and form a mating connection with the avoidance structure 37.

[0023] While keeping the crossbeam 2 unchanged, the structure of the longitudinal beam 3 was improved by setting up the avoidance structure 37. The structure of the avoidance structure 37 is exactly matched with the crossbeam 2. During assembly, the crossbeam 2 can be embedded with the avoidance structure 37, so that the top of the longitudinal beam 3 can be in complete contact with the bottom surface of the base plate 1. Without changing the structural strength of the crossbeam 2, the number of welding points and the fit of the longitudinal beam 3 are increased. The contact area between the longitudinal beam 3 and the base plate 1 is greatly increased, the stress is more even, and the number of welding points between the longitudinal beam 3 and the base plate 1 and between the longitudinal beam 3 and the crossbeam 2 is also greatly increased, making the structure more robust.

[0024] The manufacturing process of the three-wheeled vehicle's floor support structure is simpler, allowing for better control over structural consistency, reducing production control difficulties, lowering costs, increasing strength, and making it more durable.

[0025] As an optional implementation, the clearance structure 37 is a slot, the shape of which matches the cross-sectional shape of the beam 2. With this configuration, the beam 2 can be embedded in the clearance structure 37, achieving a perfect fit with the clearance structure 37, so that the two can form a tight and flat contact, making the force more uniform and effectively improving the overall structural strength of the supporting and fixed structure.

[0026] In this embodiment, the slot is preferably formed by laser equipment.

[0027] As an optional implementation, the crossbeam 2 is a rectangular tube structure with good structural strength. Its top can form a tight and flat contact with the bottom surface of the base plate body 1. After being connected by welding, the structural strength of the supporting and fixed structure can be further increased.

[0028] The longitudinal beam 3 offers a variety of structural options, allowing for flexible selection based on actual usage requirements. This application document preferably demonstrates two specific structural forms.

[0029] In the first structural form, the longitudinal beam 3 is preferably a rectangular tube structure, which includes a first top plate 31, a first bottom plate 32, and two first side plates 33.

With this arrangement, the first top plate 31, the first bottom plate 32 and the first side plate 33 form a rectangular tube shape, which has good structural strength.

[0031] The two first side plates 33 are provided with a clearance structure 37. Under the premise that the clearance structure 37 preferably adopts the form of a slot, each first side plate 33 is provided with a number of slots, and the positions of the slots on the two first side plates 33 are mutually corresponding.

[0032] As a rectangular tube structure, the longitudinal beam 3 is actually connected to the bottom plate body 1 through the first top plate 31, and the first top plate 31 and the bottom plate body 1 can form a tight and flat contact.

[0033] In the second structural form, the longitudinal beam 3 is preferably a sheet metal structure, which includes two second top plates 34, one second bottom plate 35, and two second side plates 36.

[0034] The second base plate 35 is connected to the bottom of a second side plate 36 at each end in the horizontal direction, and the top of each second side plate 36 is connected to the inner end of a second top plate 34. With this arrangement, the second top plate 34, the second base plate 35 and the second side plate 36 can form a sheet metal structure with good structural strength.

[0035] The two second side plates 36 are provided with a clearance structure 37. Under the premise that the clearance structure 37 preferably adopts the form of a slot, each second side plate 36 is provided with a number of slots, and the positions of the slots on the two second side plates 36 are mutually corresponding.

[0036] The longitudinal beam 3 is actually connected to the bottom plate body 1 through two second top plates 34, and the second top plates 34 and the bottom plate body 1 can form a tight and flat contact.

[0037] As an optional implementation, the first top plate 31 is welded to the bottom plate body 1. The welded connection has good connection strength and is easier to construct.

[0038] As an optional implementation, both second top plates 34 are welded to the bottom plate body 1. The welded connection has good connection strength and is easier to construct.

[0039] As an optional implementation, it also includes side panels 4. The four outer edges of the base plate body 1 are each connected to the top of a side panel 4. Each end of each crossbeam 2 is connected to a side panel 4 parallel to the length direction of the longitudinal beam 3. Each end of each longitudinal beam 3 is connected to a side panel 4 parallel to the length direction of the crossbeam 2. The addition of side panels 4 can further improve the structural strength and enhance the stability of the supporting and fixed structure.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
