[0019] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0020] For ease of description, the words "upper," "lower," "front," and "rear" appearing in this invention only indicate that they are consistent with the upper, lower, front, and rear directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1: This embodiment provides a floating device for an amphibious vehicle, including a wave deflector 1 and a buoy 2. The wave deflector 1 is used to deflect water and reduce navigation resistance; the buoy 2 is used to cooperate with the wave deflector 1 to increase the overall buoyancy.

[0022] Specifically, such as Figures 1-3 As shown, the wave deflector 1 includes a top plate 11, a back plate 13, side plates 14, a water-dividing plate 12, and a water-supporting plate 16. The wave deflector 1 is a box-shaped structure composed of the top plate 11, the back plate 13, the water-supporting plate 16, two side plates 14, and two water-dividing plates 12. The height of the back plate 13 is greater than the height of the water-dividing plate 12, and the front edge of the side plate 14 is a sloping edge. The water-supporting plate 16 is located below the water-dividing plate 12 and is fixed to the side plate 14. Through the above structure, a cavity is formed inside the wave deflector 1, and the bottom is an open structure.

[0023] A fastener 18 is installed at the bottom of the back plate 13, and the fastener 18 is connected to the vehicle body by bolts. In this embodiment, the fastener 18 is located in the middle of the back plate 13, and the fastener 18 is provided with mounting holes. At the same time, mounting holes are symmetrically arranged on the back plate 13 near the top relative to the fastener 18, forming three mounting positions, so that the wave deflector 1 is stably connected to the vehicle body.

[0024] To facilitate assembly with the vehicle body, the back plate 13 in this embodiment has an arc-shaped cross-section. Two water-dividing plates 12 are symmetrically installed relative to the back plate 13, with the plates 12 inclined relative to the vertical plane. A certain water-dividing angle is formed between the two plates 12, giving the front end of the wave deflector 1 a conical structure. The water-dividing angle is obtuse, effectively diverting water during driving, reducing vehicle resistance in water, and increasing vehicle speed in water.

[0025] In this embodiment, the water-dividing angle is 127°; it is understood that in other embodiments, the water-dividing angle can be adjusted to other values ​​according to actual requirements to achieve the best water-dividing effect.

[0026] like Figure 2 As shown, multiple reinforcing ribs 15 are installed inside the cavity of the wave deflector 1 to increase its strength. Arc-shaped reinforcing ribs 15, adapted to the cross-sectional shape, are distributed along the inner surface of the back plate 13. These arc-shaped reinforcing ribs 15 are connected by longitudinal reinforcing ribs 15. The back plate 13 and the water distribution plate 12 are also connected by reinforcing ribs 15. Multiple arc-shaped reinforcing ribs 15 connect the lower side of the water distribution plate 12 to the back plate 13, supporting the water-supporting plate 16, which is bent towards the cavity side. The arc-shaped water-supporting plate 16, in conjunction with the water distribution plate 12, provides better water distribution.

[0027] The cavity is filled with foam and expanding foam. The foam material has low density and high buoyancy, effectively providing stable and long-lasting buoyancy. For the box-shaped wave deflector 1, foam and expanding foam are filled into the cavity through pre-drilled holes 17 in the wave deflector 1. After filling, the pre-drilled holes 17 need to be sealed. Figure 1 As shown, this embodiment has two pre-drilled holes 17 on the back plate 13 to facilitate the filling of the cavity with foam and expanding foam. Of course, the position of the pre-drilled holes 17 can also be adjusted according to actual requirements.

[0028] In this embodiment, a plurality of drainage holes 19 are evenly distributed on the lower side of the back plate 13. The drainage holes 19 can automatically drain the water inside the wave deflector 1 after the vehicle is taken ashore, thus preventing corrosion.

[0029] In this embodiment, the wave-breaking plate 1 is integrally welded. After welding, the surface of the wave-breaking plate 1 is powder-coated to prevent corrosion. Then, foam and expanding foam are filled into the cavity through the reserved holes 17, and the reserved holes 17 are sealed after filling. The foam accounts for 90% and the expanding foam accounts for 10%; of course, the above proportions can be adjusted adaptively.

[0030] In this embodiment, the floating device primarily uses a wave-damping plate 1, supplemented by two side floats 2, to enhance buoyancy and reduce resistance. For example... Figures 4-6 As shown, the float 2 includes a box body 21 and a bottom plate 22, with the bottom plate 22 detachably installed at the bottom of the box body 21. The main body of the box body 21 is a cuboid structure, with an end plate at the front end of the box body 21. The end plate has an inclined surface 23, which forms an acute angle with the horizontal plane. In this embodiment, the angle between the inclined surface 23 and the horizontal plane is 30°. It can be understood that the above angle can be adaptively adjusted according to actual requirements.

[0031] The enclosure 21 is manufactured by welding, and the surface is powder-coated after welding to prevent corrosion. The enclosure 21 is filled with foam and expanding foam adhesive, and the base plate 22 is then fixed to the enclosure 21 after filling. Figure 5 As shown, multiple support ribs 24 are provided on the inner side of the base plate 22. Each support rib 24 is arranged along the length of the base plate 22, increasing the support strength of the base plate 22. Multiple mounting holes are arranged on the support ribs 24, and connectors 25 are installed in these mounting holes to connect the base plate 22 to the housing 21. In this embodiment, bolts are used as connectors 25.

[0032] like Figure 5 and Figure 6 As shown, the base plate 22 is provided with multiple through holes 26. This serves two purposes: firstly, it reduces weight; secondly, it creates a non-sealed space in the float box 2, allowing water entering the float box 2 to flow out through the through holes 26 after the vehicle exits the water. Furthermore, the foam material filling the float box 2 further prevents corrosion. In this embodiment, the base plate 22 is provided with multiple rows of through holes 26, with adjacent rows staggered to allow water to flow into and out of the float box 2 evenly.

[0033] In this embodiment, the wave deflector 1, with its box-shaped structure, front-end water-dividing angle, and bottom arc-shaped water-supporting plate 16 combined with internal foam material, can improve the vehicle's stability when entering water by suppressing waves, making the pressure distribution under the vehicle body more uniform, reducing the pitch angle, and maintaining driving stability. At the same time, the float box 2 has the function of increasing buoyancy and reducing drag, increasing the vehicle's stability when entering water and the vehicle's speed in the water.

[0034] Furthermore, both the wave deflector 1 and the pontoon 2 in this embodiment are non-sealed structures, which can increase contact with air and moisture during the foam and expanding foam filling process, ensuring the foaming effect, allowing the foam to fill the entire internal space, and reducing the overall weight of the wave deflector 1 and the pontoon 2.

[0035] Example 2: This embodiment provides an amphibious vehicle, including a vehicle body equipped with the floating device described in Embodiment 1. A wave deflector 1 is installed at the front of the vehicle body. When navigating on water, the wave deflector 1 prevents water from rushing into the front of the vehicle, protecting the vehicle's interior from water ingress, and also increases the buoyancy of the front of the vehicle. Float boxes 2 are symmetrically arranged on both sides of the vehicle body. After the vehicle enters the water, the lifting height of the front and rear wheels is consistent with the position of the float boxes 2. The float boxes 2 act as anti-roll fins, preventing the vehicle from swaying left and right, providing a balancing effect, and effectively reducing drag. Through the cooperation of the wave deflector 1 and the float boxes 2, the vehicle can move steadily in the water.

[0036] In this embodiment, the vehicle body is a pickup truck with a high chassis. The floats 2 are located on both sides of the vehicle body and can also serve as steps to facilitate people getting on and off the vehicle.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
