Description

Technical Field

[0001] This invention relates to a driver's cab, and more particularly to a reconfigurable aluminum alloy driver's cab. Background Technology

[0002] Currently, most airport fire trucks are converted from civilian vehicle cabs. These cabs severely restrict the timeliness of fire truck rescue, the comfort of passengers, and the awareness of fire situation in terms of weight, visibility, and space. Therefore, some airports in China have introduced foreign specialized fire trucks. The cabs of these specialized fire trucks are mostly covered with large areas of glass, with aluminum alloy frames and aluminum alloy or carbon fiber skins. However, aluminum alloy is prone to welding deformation, is more expensive than steel, and has the risk of leakage at the riveting joints. At the same time, due to the special properties of aluminum alloy, it is difficult to repair damaged parts of the cab after a collision, and the repaired parts cannot achieve the original strength of the cab body.

[0003] Meanwhile, due to the large glass area of ​​the cab of a special fire truck, the solar heat radiation will cause a large demand for air conditioning in the cab. The arrangement of the air conditioning will sacrifice the space inside the cab, so how to reasonably arrange the air conditioning and air ducts is also a major problem. Summary of the Invention

[0004] The purpose of this invention is to provide a reconfigurable aluminum alloy cab to address the shortcomings of existing technologies, thereby solving the problems mentioned in the background art regarding manufacturing deformation, repair, cost, sealing, space, and thermal comfort of existing cabs.

[0005] This invention is achieved using the following technical solution: A reconfigurable aluminum alloy cab includes a front bulkhead assembly, comprising a front bulkhead frame assembly and a front bulkhead skin riveted together; The left side bulkhead assembly includes the riveted left side bulkhead frame assembly and the left fender skin; The right side bulkhead assembly includes the riveted right side bulkhead frame assembly and the right fender skin; Floor assembly, including the floor frame assembly and floor skin riveted together; The rear assembly includes the rear frame assembly and the rear skin welded together; The roof assembly includes the roof frame assembly and the roof skin welded together; The front bulkhead assembly, left side bulkhead assembly, right side bulkhead assembly, floor assembly, rear bulkhead assembly, and roof assembly together form the fire truck cab structure.

[0006] Furthermore, the front frame assembly, front skin, left side frame assembly, left fender skin, right side frame assembly, right fender skin, floor frame assembly, floor skin, rear frame assembly, rear skin, roof frame assembly, and roof skin are all made of aluminum alloy; the connecting parts between the front frame and the floor frame, the connecting parts between the front frame and the left and right side frames, the connecting parts between the roof frame and the side frames, the connecting parts between the roof frame and the rear frame, the connecting parts between the rear frame and the floor frame, and the connecting parts between the floor frame and the left and right side frames are all made of alloy structural steel.

[0007] Furthermore, the aluminum profiles in the front frame assembly are welded into a closed structure. The main load-bearing profile is a hollow rectangular aluminum profile, and the profiles connected to the left side frame assembly, the right side frame assembly, and the floor frame assembly are angular aluminum profiles. The angular aluminum profiles of the front frame assembly are riveted to the left side frame assembly, the right side frame assembly, and the floor frame assembly, and alloy structural steel profiles are screwed at the main load-bearing frame.

[0008] Furthermore, the aluminum profiles in the left and right perimeter frame assemblies are welded into a closed structure, the main side perimeter frame has an irregular cross-section aluminum profile, and the remaining frames have rectangular aluminum profiles.

[0009] Furthermore, the aluminum profiles in the floor frame assembly are welded into a closed structure. The main load-bearing profile is a hollow rectangular aluminum profile, and the profiles connected to the left and right perimeter frame assemblies are angular aluminum profiles. The angular aluminum profiles of the floor frame assembly are riveted to the left and right perimeter frame assemblies, and alloy structural steel profiles are screwed at the main load-bearing frame.

[0010] Furthermore, the aluminum profiles in the rear frame assembly are welded into a closed structure. The main load-bearing profile is a hollow rectangular aluminum profile, and the profiles connecting the left side frame assembly, right side frame assembly, floor frame assembly, and roof frame assembly are angular aluminum profiles. The angular aluminum profiles of the rear frame assembly are riveted to the side frame assembly, floor frame assembly, and roof frame assembly, and alloy structural steel profiles are screwed at the main load-bearing frame.

[0011] Furthermore, the connection between the rear frame assembly and the top cover frame assembly is recessed inward to accommodate the air conditioner; the middle frame of the top cover frame assembly is rectangular and serves as the air conditioning duct.

[0012] Furthermore, a polyurea material layer is provided on the top cover skin, and it covers the air conditioning duct.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: The cab body of this invention uses six large frame pieces for closed welding to reduce deformation of each frame piece. When a certain part is hit by a collision, it can be quickly replaced and reconstructed without damaging the original body structure, thus ensuring the body strength. By riveting the skin, welding deformation of large parts is reduced. By riveting and bolting the large parts frame, body assembly deformation and sealing are reduced. By setting recesses in the rear panel and roof frame, and by having the roof frame act as an air duct, the air conditioning layout and thermal comfort issues are solved. By selecting profiles, a low-cost, fast-cycle small-batch production mode can be met. Attached Figure Description
