Description

Technical Field

[0001] The present invention relates to a cab, and in particular to a new type of reconfigurable aluminum alloy cab. Background Art

[0002] At present, most airport fire trucks are modified from civilian vehicle cabs. Such cabs severely restrict the timeliness of fire truck rescue, the comfort of the crew, and the perception of the fire scene situation in terms of weight, visibility, space, etc. Therefore, some domestic airports have introduced foreign special fire trucks. The cabs of special fire trucks mostly use large-area glass coverage, the frame is made of aluminum alloy, and the skin is made of aluminum alloy or carbon fiber. However, aluminum alloy is prone to welding deformation, is more expensive than steel, and there is a risk of rain leakage at the riveted joints. At the same time, due to the special nature of the aluminum alloy material, it is difficult to repair the damaged parts of the cab body after being collided, and the original strength of the cab body cannot be achieved after repair.

[0003] At the same time, due to the large glass area of the cab of the special fire truck, solar heat radiation will cause a large demand for the cooling load of the cab air conditioner. The layout of the air conditioner will sacrifice the space inside the cab. Therefore, how to reasonably arrange the air conditioner and air duct is also a major problem. Summary of the Invention

[0004] The purpose of the present invention is to provide a new type of reconfigurable aluminum alloy cab in view of the deficiencies of the prior art, so as to solve the problems existing in the existing cab in terms of manufacturing deformation, repair, cost, sealing, space, thermal comfort, etc. mentioned in the above background art.

[0005] The present invention is implemented by adopting the following technical solutions:

[0012] Among them, the front panel assembly, the left side panel assembly, the right side panel assembly, the floor assembly, the rear panel assembly, and the roof assembly enclose the structure of the fire truck cab.

[0013] Furthermore, the front wall frame assembly, front wall skin, left side wall frame assembly, left fender skin, right side wall frame assembly, right fender skin, floor frame assembly, floor skin, rear wall frame assembly, rear wall skin, roof frame assembly, and roof skin are all made of aluminum alloy; the connectors between the front wall frame and the floor frame, between the front wall frame and the left and right side wall frames, between the roof frame and the side wall frames, between the roof frame and the rear wall frame, between the rear wall frame and the floor frame, and between the floor frame and the left and right side wall frames are all made of alloy structural steel.

[0014] Furthermore, the aluminum profiles in the front wall frame assembly are welded into a closed structure. The main load-bearing profiles are hollow rectangular aluminum profiles, and the profiles connecting to the left side wall frame assembly, right side wall frame assembly, and floor frame assembly are angle aluminum profiles; the angle aluminum profiles of the front wall frame assembly are riveted to the left side wall frame assembly, right side wall frame assembly, and floor frame assembly, and alloy structural steel profiles are screwed at the main load-bearing skeleton.

[0015] Furthermore, the aluminum profiles in the left side wall frame assembly and right side wall frame assembly are welded into a closed structure. The cross-section of the main side wall frame is a special-shaped cross-section aluminum profile, and the other skeletons are rectangular aluminum profiles.

[0016] Furthermore, the aluminum profiles in the floor frame assembly are welded into a closed structure. The main load-bearing profiles are hollow rectangular aluminum profiles, and the profiles connecting to the left side wall frame assembly and right side wall frame assembly are angle aluminum profiles; the angle aluminum profiles of the floor frame assembly are riveted to the left side wall frame assembly and right side wall frame assembly, and alloy structural steel profiles are screwed at the main load-bearing skeleton.

[0017] Furthermore, the aluminum profiles in the rear wall frame assembly are welded into a closed structure. The main load-bearing profiles are hollow rectangular aluminum profiles, and the profiles connecting to the left side wall frame assembly, right side wall frame assembly, floor frame assembly, and roof frame assembly are angle aluminum profiles; the angle aluminum profiles of the rear wall frame assembly are riveted to the side wall frame assembly, floor frame assembly, and roof frame assembly, and alloy structural steel profiles are screwed at the main load-bearing skeleton.

[0018] Furthermore, the connecting part in the middle of the rear wall frame assembly and the roof frame assembly is recessed inward for arranging the air conditioner; the middle skeleton of the roof frame assembly is rectangular and serves as the air-conditioning duct.

[0019] Furthermore, a polyurea material layer is provided on the roof skin and covers the air-conditioning duct.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] The cab body of the present invention uses six large-frame structures for closed welding to reduce the deformation of each large-frame structure. When a certain part is collided, it can be quickly replaced and reconstructed without damaging the original body structure, ensuring the body strength.

[0022] By riveting the skin, the welding deformation of each large piece is reduced. By the form of riveting and bolt connection of each large-frame structure, the assembly deformation and sealing of the body are reduced. By setting depressions in the rear wall and roof frame, and using the roof frame as the air duct, the problems of air-conditioning layout and thermal comfort are solved. Through the selection of profiles, it can meet the low-cost and fast-cycle small-batch production mode. Brief Description of the Drawings
