[0002] At present, the main equipment capable of autonomous sea crossing and rapid river crossing is specially developed amphibious vehicles. Amphibious vehicles take into account the technical requirements of land use and sea crossing. However, due to the walking mechanism and overall layout requirements for land use, it is difficult to design the shape into a streamlined shape. Therefore, during the sea crossing process, it is necessary to first overcome a large form drag before it is possible to significantly increase the sailing speed.

[0003] In view of the drag characteristics of tracked vehicles in water, inflatable film structures are respectively arranged at appropriate positions to wrap the entire track of the vehicle body. The inflatable film structure can provide a certain buoyancy for the whole, raise the vehicle body as a whole, and make the vehicle have a more excellent shape in water without affecting the positions of the overall center of gravity and center of buoyancy, while reducing the form drag and wave-making drag. Summary of the Invention

After the vehicle body airbag is inflated on both sides of the crawler and deployed until it reaches a predetermined value; in the transition state, the air pressure of the vehicle body airbag is reduced through the air release valve in the gas generator and the discharge device, the deployment cable is retracted through the recovery motor, and the deployment motor synchronously releases the deployment cable, so that the vehicle body airbag is gradually pulled back and recovered into the vehicle body airbag storage cylinder.

[0011] Furthermore, the fixed guide wheel is connected to the vehicle body through a micro-explosion bolt.

[0019] To make the objectives, contents and advantages of the present invention clearer, the following further describes in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings and embodiments.

[0020] This embodiment proposes an inflatable film buoyancy-aiding and drag-reducing airbag carrying system for a vehicle, and its structure is as Figures 1-5 shown, mainly including a vehicle head airbag module 1 and a vehicle body airbag module 2.

[0021] The vehicle head airbag module 1 is arranged at the original anti-wave board position of the vehicle head, and includes a vehicle head airbag storage cylinder 1-1, a vehicle head airbag 1-2, a folding head cone, a vehicle head airbag inflation control unit, a gas generator and an inflation assembly. Among them, the vehicle head airbag 1-2, the folding head cone and the vehicle head airbag inflation control unit are all installed in the vehicle head airbag storage cylinder 1-1.

[0022] In the carrying state, the vehicle head airbag storage cylinder 1-1 is folded in the front part of the vehicle body. After the vehicle enters the water, the vehicle head airbag storage cylinder 1-1 is converted from the folded state to the deployed and water-entry state by using the support frame 1-3. The vehicle head airbag inflation control unit controls the pyrotechnic gas generator to ignite and work in a timely manner, and inflates the vehicle head airbag 1-2 quickly through the inflation assembly. After being inflated, the vehicle head airbag 1-2 is directly deployed, forms an inflatable cone structure by using the folding head cone, and extends backward to the front of the crawler. The fully inflated vehicle head airbag 1-2 can form a bow structure convenient for underwater navigation in front of the crawler. The folding head cone is covered on the outside of the vehicle head airbag 1-2, and can bear most of the hydraulic impact in the navigation state, avoiding the vehicle head airbag 1-2 from being damaged by the impact.

[0023] The vehicle body airbag module 2 includes a vehicle body airbag storage cylinder 2-1, a vehicle body airbag 2-2, a vehicle body airbag inflation control unit 2-3, a deployment motor 2-4, a recovery motor 2-5, a slide rail 2-6, a fixed guide wheel 2-7, a deployment cable 2-8, a gas generator and a release device 2-9, and an inflation assembly. Among them, the vehicle body airbag storage cylinder 2-1, the vehicle body airbag inflation control unit 2-3, the deployment motor 2-4, the recovery motor 2-5, and the gas generator and release device 2-9 are all arranged at the rear of the vehicle body, and the vehicle body airbag 2-2 is installed in the vehicle body airbag storage cylinder 2-1. The slide rail 2-6 is arranged on the side decks on both sides of the vehicle body, and a plurality of rollers are arranged in the slide rail 2-6. The fixed guide wheel 2-7 is installed at the front end of the slide rail 2-6, the deployment cable 2-8 bypasses the fixed guide wheel 2-7 and is respectively connected to the deployment motor 2-4 and the recovery motor 2-5 at both ends, and the deployment cable 2-8 is connected to each roller through a plurality of rigid buckles. A traction belt is arranged on the outer side of the vehicle body airbag 2-2, and the traction belt is connected to the deployment cable 2-8 through a plurality of L-shaped hooks 2-9.

[0024] In the on-land state, the deployment motor 2-4 and the recovery motor 2-5 do not operate, and the vehicle body airbag 2-2 is kept stored in the vehicle body airbag storage cylinder 2-1. After the vehicle enters the water, the deployment motor 2-4 pulls the deployment cable 2-8 to make the rollers move forward along the slide rail 2-6, and the recovery motor 2-5 synchronously releases the deployment cable 2-8, so that the vehicle body airbag 2-2 can be normally deployed forward from the vehicle body airbag storage cylinder 2-1. After the vehicle body airbag 2-2 is deployed in place, the vehicle body airbag inflation control unit 2-3 controls the pyrotechnic gas generator in the gas generator and release device 2-9 to ignite and work in a timely manner, and quickly inflates the vehicle body airbag 2-2 through the inflation assembly. After the vehicle body airbag 2-2 is inflated on both sides of the crawler belt, it unfolds until it reaches the predetermined value. In the transition state, first, the air release valve in the gas generator and release device 2-9 is opened to reduce the air pressure of the vehicle body airbag 2-2, and the recovery motor 2-5 starts to retract the deployment cable 2-8, and the deployment motor 2-4 synchronously releases the deployment cable 2-8, so that the vehicle body airbag 2-2 is gradually pulled back and recovered into the vehicle body airbag storage cylinder 2-1. The fixed guide wheel 2-7 is connected to the vehicle body through a micro-explosion bolt. In a combat emergency, the micro-explosion bolt is started with one key to explode the fixed guide wheel 2-7 and the deployment cable 2-8, so as to instantly discard the vehicle body airbag 2-2 as a whole, enabling the vehicle to immediately enter the on-land movement state.

[0025] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
