Description

Technical Field

[0001] This utility model relates to the field of amphibious vehicle technology, and in particular to an amphibious vehicle floating box. Background Technology

[0002] Current amphibious vehicles often use buoyancy boxes to provide buoyancy and use airbags on the buoyancy boxes to help the amphibious vehicles get out of trouble. However, there is a lack of solutions for emergency situations such as buoyancy box structural damage or water ingress.

[0003] Chinese Patent Publication No. CN 212637066 U discloses a floating box and an amphibious vehicle, including a box body. The bottom of the box body is a fully arc-shaped connecting plate. Multiple airbag guide plates are also provided on the longitudinal carrier plate at the bottom of the vehicle body. The airbag guide plate includes a limiting arc plate. The bottom surface of the limiting arc plate is a limiting arc surface that limits the airbag. The limiting arc surfaces of the multiple airbag guide plates form a guiding space that limits the direction of airbag inflation. The expansion direction of the airbags during inflation is limited by the guiding space formed by the limiting arc surfaces of multiple airbag guide plates, thereby controlling the buoyancy position of the airbags. This results in a structure where the buoyancy position of the airbags varies under different inflation states, enabling control over the buoyancy position and vehicle body status of the amphibious vehicle. However, the aforementioned float box and amphibious vehicle have the following problems: By setting multiple airbags and controlling the buoyancy position of the airbags by limiting their expansion direction with limiting arc plates, the structure is complex and has poor stability. Furthermore, if the float box has any damaged parts, the airbags cannot fundamentally solve the problem and cannot provide sufficient safety for the amphibious vehicle. Utility Model Content

[0004] Therefore, this utility model provides an amphibious vehicle floating box to overcome the problem of poor safety of amphibious vehicles in the prior art.

[0005] To achieve the above objectives, this utility model provides an amphibious vehicle buoyancy tank, which is installed in pairs on the amphibious vehicle to provide buoyancy. For a single buoyancy tank, it includes:

[0006] A buoyancy mechanism that generates buoyancy by displacing water through a cavity structure includes a structural plate and a buoyancy cavity enclosed by the structural plate, as well as air bladder cavities disposed on both sides of the buoyancy cavity.

[0007] A support mechanism that supports the structural plate through a beam frame structure disposed inside the pontoon to improve structural strength, including a support beam frame for supporting the structural plate;

[0008] The protective mechanism includes an airbag assembly disposed within the airbag chamber for reducing the amount of water entering the airbag chamber and increasing buoyancy; and a drainage assembly disposed within the airbag chamber and communicating with the buoyancy chamber for draining water when the buoyancy chamber is filled with water.

[0009] Furthermore, the structural plate includes an upper plate, a bottom plate, an inner partition plate, an end plate, an inner side plate, an outer side plate, and a sealing plate;

[0010] The inner side plate includes a left inner side plate and a right inner side plate, which are welded together with the upper plate, the bottom plate and the end plate to form the buoyancy cavity;

[0011] The outer side plate includes a left outer side plate and a right inner and outer side plate, which are respectively disposed on the outer side of the inner side plate and welded together with the upper plate, the bottom plate and the sealing plate to form the airbag cavity, which includes a left airbag cavity and a right airbag cavity.

[0012] Furthermore, it also includes support columns, of which there are several, which are respectively welded to the upper surface corresponding to the welding combination position of the upper plate and the inner side plate, to support the amphibious vehicle body structure, separate the vehicle body from the pontoon, and provide space for the amphibious vehicle tracks.

[0013] Furthermore, the base plate is an integral arc-shaped structure.

[0014] Furthermore, the inner partition includes a buoyancy cavity partition and an airbag cavity partition, which divide the internal space of the float box into two equal parts. The buoyancy cavity partition is welded to the left inner side plate and the right inner side plate to divide the buoyancy cavity into a front buoyancy cavity and a rear buoyancy cavity. The airbag cavity partition includes a left airbag cavity partition and a right airbag cavity partition. The left airbag cavity partition is welded to the left inner side plate and the left outer side plate to divide the left airbag cavity into a left front airbag cavity and a left rear airbag cavity. The right airbag cavity partition is welded to the right inner side plate and the right outer side plate to divide the right airbag cavity into a right front airbag cavity and a right rear airbag cavity.

[0015] Furthermore, the airbag assembly includes an airbag disposed within the airbag cavity, and an inflation solenoid valve, a deflation solenoid valve, an air tank, and a compressor connected to the airbag and disposed on the amphibious vehicle body.

[0016] Furthermore, the airbag includes a left front airbag, a left rear airbag, a right front airbag, and a right rear airbag, which are respectively disposed in the corresponding airbag cavities, and each airbag can be independently controlled to inflate or deflate.

[0017] Furthermore, the drainage assembly includes a drainage pump bracket disposed within the airbag cavity, a drainage pump disposed on the drainage pump bracket, a water pumping hose connecting the bottom of the buoyancy cavity to the drainage pump, and a drainage hose connecting the drainage pump to the outside of the float.

[0018] Furthermore, the drainage pump bracket includes a bracket fixing plate, a bracket bending plate, and a drainage hole;

[0019] The bracket fixing plate is located on the outer side of the outer side plate, and the bracket bending plate is fixed on the inner side of the outer side plate by bolt connection, so as to install the drainage pump in the airbag cavity; the bracket fixing plate, the bracket bending plate and the outer side plate are provided with concentric circular openings of equal diameter to form the drainage hole, which is used to install the drainage hose; the inner side plate is provided with a circular opening, which is used to install the water pumping hose.

[0020] Furthermore, the supporting beam, the structural plate, the supporting column, and the drainage pump bracket are made of salt-resistant aluminum alloy.

[0021] Compared with the prior art, the beneficial effect of this utility model is that the utility model is provided with drainage pump brackets located on both sides of the inner partition, which can drain the two buoyancy chambers of the float box respectively, ensuring the safety of the amphibious vehicle when the buoyancy chambers are filled with water.

[0022] Furthermore, the airbag cavity is located outside the buoyancy cavity. When the amphibious vehicle is damaged by a lateral impact, water will first enter the airbag cavity, protecting the buoyancy cavity. After the airbag in the corresponding position is inflated, it will occupy the volume inside the airbag cavity, reducing the amount of water that can enter and increasing buoyancy, thus improving safety.

[0023] Furthermore, the airbags include a left front airbag, a left rear airbag, a right front airbag, and a right rear airbag. Each airbag can be independently controlled to inflate or deflate. When the amphibious vehicle tilts during operation, the airbag in the tilt direction can be inflated individually to balance the buoyancy at the corresponding position, thus improving safety.

[0024] Furthermore, the bottom of the pontoon adopts a fully arc-shaped structural plate to reduce water flow resistance;

[0025] Furthermore, the supporting beams, structural plates, supporting columns, and drainage pump brackets are made of salt-resistant aluminum alloy, which has high structural strength and light weight. In addition, since the amphibious vehicle needs to face a water environment with complex composition, its good resistance to salt corrosion ensures the overall stability of the equipment.
