Description

Technical Field

[0001] This utility model belongs to the field of amphibious vehicle technology. Specifically, this utility model relates to a wheel baffle flipping mechanism based on an amphibious vehicle. Background Technology

[0002] In the application of amphibious vehicles, improving their water navigation performance is crucial. When vehicles navigate on water, they are subject to various forms of resistance, among which the resistance generated by the wheels, wheel wells, and related components in the water is significant. This resistance not only reduces vehicle speed but also increases energy consumption, limiting the vehicle's operational range and efficiency on water. Existing wheel drag reduction solutions for amphibious vehicles involve filling wheel wells with airbags, but these methods have significant drawbacks. A novel technological solution is urgently needed to reduce the resistance generated by the wheels, wheel wells, and related components in the water, thereby improving the overall navigation performance of amphibious vehicles.

[0003] Utility model patent CN211364184U, published on August 28, 2020, discloses a drag-reducing structure for an amphibious vehicle body. It comprises a front curved bottom plate, a left bow pillar plate, a right bow pillar plate, and a light mounting bracket. The entire body is made of aluminum alloy and welded together. The front bottom surface features a large curved design, with the bow pillar protruding from the lower part. The bow pillar is formed by welding symmetrical left and right bow pillar plates, both made of 3mm thick aluminum alloy. The bow pillar and the light mounting bracket on the upper part of the large curved surface are welded together to form the front bottom. However, this drag-reducing structure for an amphibious vehicle body does not solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple wheel flap tilting mechanism based on amphibious vehicles that reduces the resistance of vehicles navigating on water.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The amphibious vehicle-based wheel flap flipping mechanism includes a vehicle body. The bottom of the vehicle body is provided with mounting seats and brackets on both sides of the wheel flap. The bottom ends of the wheel flap are rotatably connected to the mounting seats and brackets, respectively. The mounting seats are provided with swing cylinders, and the swing cylinders are connected to a power transmission mechanism.

[0007] The power transmission mechanism includes a coupling, a first bevel gear, and a second bevel gear. The two ends of the coupling are respectively connected to the output end of the swing cylinder and the first bevel gear, and the first bevel gear meshes with the second bevel gear. The bottom ends of the wheel baffle are respectively provided with a first fixing plate and a second fixing plate. A sleeve is fixedly connected to the end of the mounting base. The second bevel gear is connected to a first connecting shaft. The first connecting shaft passes through the sleeve and is fixedly connected to the first fixing plate. A second connecting shaft is fixedly connected to the bottom of the second fixing plate. The end of the second connecting shaft is rotatably connected to the bracket.

[0008] The wheel baffle has a rotation angle range of 0° to 270°.

[0009] The vehicle body is provided with receiving grooves on the sides and bottom, and the receiving grooves are adapted to the wheel baffles.

[0010] The first connecting shaft is welded to the first fixing plate with reinforcing ribs, and the second connecting shaft is welded to the second fixing plate with reinforcing ribs.

[0011] Both the first fixing plate and the second fixing plate are connected to the wheel baffle by multiple bolts.

[0012] The wheel baffle has an clearance opening at the bottom.

[0013] The wheel baffle is located on the side of the vehicle body and within a receiving groove.

[0014] The wheel guard is located at the bottom of the vehicle body and below the wheel, and an avoidance opening extends from the bottom of the wheel.

[0015] The technical advantages of this invention are as follows: The wheel baffle tilting mechanism based on an amphibious vehicle achieves a 270° tilt via a swing cylinder, suitable for both land-based and water-based driving conditions. The tilting of the wheel baffle seals the wheel well space, reducing water resistance generated by the wheels, wheel wells, and related components, thus improving the overall navigation performance of the amphibious vehicle. The wheel baffle structure is rationally designed, occupies little vehicle space, has a simple overall structure, and low application cost. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0026] like Figure 1 and Figure 2 As shown, the amphibious vehicle-based wheel fender tilting mechanism includes a vehicle body 1. At the bottom of the vehicle body 1, on both sides of the wheel fender 3, are mounting seats 4 and brackets 5, respectively. The bottom ends of the wheel fender 3 are rotatably connected to the mounting seats 4 and brackets 5, respectively. A swing cylinder 6 is mounted on the mounting seat 4, and the swing cylinder 6 is connected to a power transmission mechanism. The mounting seat 4 is fixed to the vehicle body 1 for mounting the swing cylinder 6. The bracket 5 is positioned relative to the mounting seat 4, and its mounting shaft provides balanced support for the rotation of the wheel fender 3. The swing cylinder 6 provides power for the 270° tilting of the wheel fender 3. The structure is simple and low-cost. The wheel fender 3 is made of aluminum alloy, which has the advantages of being lightweight and high-strength, not easily damaged or aged, and requires less frequent maintenance. While ensuring sufficient strength to withstand water flow impact, its own weight is minimized to reduce the impact on the overall performance of the vehicle. When the wheel baffle 3 is vertically retracted, it is located outside the vehicle body 1 and outside the wheel 2. When the wheel baffle 3 is horizontally extended, it is located below the wheel 2 and seals the wheel cavity. When the airbag fills the wheel cavity, it reduces drag and increases speed when the vehicle is sailing in water, reduces energy consumption, and improves the convenience of the vehicle in water operations.

[0027] like Figure 3 As shown, the power transmission mechanism includes a coupling 7, a first bevel gear 8, and a second bevel gear 9. The two ends of the coupling 7 are connected to the output end of the swing cylinder 6 and the first bevel gear 8, respectively, and the first bevel gear 8 meshes with the second bevel gear 9. The bottom ends of the wheel baffle 3 are respectively provided with a first fixing plate 13 and a second fixing plate 14. A sleeve 10 is fixedly connected to the end of the mounting base 4. The second bevel gear 9 is connected to a first connecting shaft 11, which passes through the sleeve 10 and is fixedly connected to the first fixing plate 13. A second connecting shaft 12 is fixedly connected to the bottom of the second fixing plate 14, and the end of the second connecting shaft 12 is rotatably connected to the bracket 5. The swing cylinder 6 transmits power through a pair of bevel gears, making its axis 90° with the rotation axis of the wheel baffle 3, thus changing the direction of power transmission. This also facilitates the installation of the swing cylinder 6 on the vehicle body 1 and on the side of the wheel baffle 3, reducing space occupation. Each wheel 2 is equipped with a wheel baffle 3, and each wheel baffle 3 is hinged together by two connecting shafts, achieving a flipping action through the power of the swing cylinder 6. The second bevel gear 9 transmits power to the wheel baffle 3 via the key 19 of the connecting rod 18, which is fixedly connected to it.

[0028] like Figures 4-1 to 7 As shown, the wheel baffle 3 rotates within a range of 0° to 270°. When the vehicle is traveling on land, the swing cylinder 6 is in its initial 0° position, and the wheel baffle 3 is vertical, which does not affect the vehicle's travel on land. After the vehicle enters the water, the swing cylinder 6 rotates 270° under hydraulic pressure, driving the coupling 7 and a pair of bevel gears to rotate. This causes the wheel baffle 3 to swing 270° around the connecting shaft at the bottom of the wheel 2, sealing the wheel cavity in a horizontal position. This reduces drag and increases speed when the amphibious vehicle is traveling in water.

[0029] like Figure 1 and Figure 2 As shown, the sides and bottom of the vehicle body 1 are provided with receiving grooves 16, which are adapted to the wheel baffles 3. When the wheel baffles 3 are vertically retracted, they are located in the receiving grooves 16, making the outer surface of the vehicle body 1 flat, which has the effect of reducing wind resistance and can minimize the space occupied by other parts of the vehicle. The bottom of the vehicle body 1 is designed in the same way to reduce water resistance.

[0030] like Figure 4-2 As shown, the first connecting shaft 11 is welded to the first fixing plate 13 with reinforcing ribs 15, and the second connecting shaft 12 is welded to the second fixing plate 14 with reinforcing ribs 15. The reinforcing ribs 15 improve the structural strength of the fixing plate itself, and also form a connection with the connecting shaft, improving the support strength of the connecting shaft and improving the stability of the wheel baffle 3.

[0031] like Figure 4-1 and Figure 4-2As shown, both the first fixing plate 13 and the second fixing plate 14 are connected to the wheel baffle 3 by multiple bolts. These multiple bolts improve installation stability and facilitate replacement if the wheel baffle 3 is deformed or damaged.

[0032] like Figures 4-1 to 7 As shown, the wheel baffle 3 has an avoidance opening 17 at its bottom. The avoidance opening 17 is used to avoid the wheel 2, so that it does not interfere with the space of the wheel 2 during the flipping process. The top of the wheel baffle 3 is also provided with a notch for avoidance when in the horizontal unfolded position. With the above-mentioned special shape design, the wheel baffle 3, in the unfolded state, has its outline closely fits the wheel 2 and the wheel cavity, which can effectively block the direct impact of water flow on the wheel 2 and the wheel cavity, and ensure the effectiveness of the airbag sealing the wheel cavity.

[0033] like Figure 1 As shown, the wheel baffle 3 is located on the side of the vehicle body 1 and within the receiving groove 16. The above structure represents the vertical state of the wheel baffle 3 when the vehicle is traveling on land. With the swing cylinder 6 in the initial 0° position, the wheel baffle 3 is in a vertical state and does not affect the vehicle's travel on land.

[0034] like Figure 2 As shown, the wheel baffle 3 is located at the bottom of the vehicle body 1 and below the wheel 2, with an avoidance opening 17 extending from the bottom of the wheel 2. The above structure represents the wheel baffle 3 after the vehicle is submerged in water. The swing cylinder 6 rotates 270° under hydraulic pressure, driving the coupling 7 and a pair of bevel gears to rotate, thereby causing the wheel baffle 3 to swing 270° around the connecting shaft at the bottom of the wheel 2, sealing the wheel cavity in a horizontal state. This reduces drag and increases speed when the amphibious vehicle is navigating in water.

[0035] The existing airbag filling solution involves inflating a rubber airbag to fill the wheel cavity, which can seal part of the wheel cavity space. However, due to the lack of a wheel baffle 3, the effect of sealing the entire wheel cavity is limited, resulting in limited drag reduction in water. After the vehicle is launched into the water using this wheel baffle tilting mechanism, the power transmission path is: hydraulic power source → 270° swing cylinder 6 → coupling 7 → first bevel gear 8 → second bevel gear 9 → wheel baffle 3. The wheel baffle 3 rotates 270° to close the space under the wheel 2. Combined with the airbag inflation filling the wheel cavity, this seals the wheel cavity, greatly reducing the water resistance to the vehicle during navigation, improving the overall navigation performance of the amphibious vehicle, and enabling automatic deployment and retraction, which greatly reduces subsequent maintenance time and costs.

[0036] This amphibious vehicle-based wheel baffle tilting mechanism uses a swing cylinder 6 to drive the wheel baffle 3 to tilt 270°, suitable for both land-based and water-based operation. The tilting of the wheel baffle 3 seals the wheel cavity space, reducing water resistance generated by the wheel 2, wheel cavity, and related components, thus improving the overall navigation performance of the amphibious vehicle. The wheel baffle 3 has a reasonable structural design, occupies little space in the vehicle body 1, has a simple overall structure, and low application cost.

[0037] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
