Description

Technical Field

[0001] This utility model belongs to the field of amphibious vehicle technology, and more specifically, it relates to a connecting bracket for the stern wing of an amphibious vehicle. Background Technology

[0002] The stern wing of an amphibious vehicle is used to control the pitch angle of the vehicle while it is moving in water. The angle of the stern wing is controlled by extending and retracting the hydraulic cylinders of the stern wing, thereby controlling the pitch angle of the amphibious vehicle while it is moving in water and ensuring its underwater posture. The stern wing is usually mounted on a stern wing bracket, which is welded to the vehicle frame. Because the existing stern wing bracket consists of two relatively thin lugs, its strength is weak, and the stress at the weld between the lugs and the vehicle frame is high, it is prone to weld tearing, which can cause accidents in actual use. The shortcomings of the existing technology are: weak stern wing bracket strength, high stress at the weld between the lugs and the vehicle frame, and susceptibility to fatigue and weld tearing.

[0003] Existing technology includes a "Miniature Amphibious Combat Vehicle" with publication number CN110774846A. This miniature amphibious combat vehicle comprises: a frame, a support frame, a rotating control panel, a conical sliding plate, a truncated cone rotating body, an engine, a gearbox, main wings, a tail fin, a transmitter, a ground-moving device, an ammunition magazine, and a firing controller. The frame includes: a floor plate, side panels, and connecting rods. The floor plate has two sets, upper and lower, connected by side panels and connecting rods. The lower floor plate is composed of one set of isosceles triangular plates and two sets of rectangular plates. However, this technology does not address the technical problems and solutions of this application. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is a connecting bracket for the stern wing of an amphibious vehicle, including a first component and a second component. The second component is connected to the first component, and the stern wing is connected to the second component. The first component includes a first plate, a second plate, a third plate, a fourth plate, and a fifth plate. The second component is connected to the fifth plate of the first component, and the first component is connected to the vehicle frame.

[0007] The second component includes a first plate, a first ear plate, and a second ear plate, which are respectively welded onto the first plate.

[0008] The first plate of the second component has multiple openings, and each fastening bolt passes through the corresponding opening and is screwed into the screw hole on the fifth plate of the first component.

[0009] The first plate, second plate, third plate, and fourth plate of the first component are each provided with a bent edge at one end of the frame, and each bent edge is provided with multiple waist-shaped holes.

[0010] The stern wing plate is movably connected to the second component's first lug plate and the second component's second lug plate via a pin.

[0011] The adjacent sides of the first plate, second plate, third plate, and fourth plate of the first component are welded together.

[0012] The front ends of the first plate of the first component, the second plate of the first component, the third plate of the first component, and the fourth plate of the first component are respectively welded to the fifth plate of the first component.

[0013] The second component has a limiting block on its first plate. The limiting block is located between the first ear plate and the second ear plate of the second component. The outer side of the limiting block is a lower outward protruding limiting block slope.

[0014] The thickness of the first plate, second plate, third plate, fourth plate, and fifth plate of the first component is between 5mm and 7mm; the thickness of the first plate, first ear plate, and second ear plate of the second component is between 7mm and 10mm.

[0015] The thickness of the limiting block is between 26mm and 34mm.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The amphibious vehicle stern wing connecting bracket of this utility model comprises a first component including a first component first plate, a second component, a third component, a fourth component, and a fifth component. These five plates are welded together to form an integral first component. The rear of the first component is connected to the vehicle frame for a fixed connection.

[0021] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0022] As attached Figure 1As shown, this utility model is a connecting bracket for the stern wing plate of an amphibious vehicle, including a first component and a second component. The second component is connected to the first component, and the stern wing plate 12 is connected to the second component. The first component includes a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, and a fifth plate 5. The second component is connected to the fifth plate 5 of the first component, and the first component is connected to the frame 13. The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structural configuration, a first component and a second component are provided. The first component includes a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, and a fifth plate 5. These five plates are welded together to form an integral first component. The rear of the first component is connected to the frame 13 for a fixed connection. The fifth plate 5 of the first component is located at the front, and the second component is connected to the fifth plate 5 of the first component for connection. The stern wing plate 12 is connected to the second component for reliable connection. Through the structural improvements described above, a distributed component structure is formed, which is then assembled to form a support structure for connecting the stern wing plates 12. The component connection is conveniently and reliably achieved through the fastening bolts 10. The stern wing plates 12 are movably connected, ensuring reliable connection while allowing for flexible movement. The distributed component design increases the support strength, avoids stress concentration that could cause weld tearing, and improves safety. The amphibious vehicle stern wing plate connecting support described in this invention has a simple structure, enabling convenient and reliable connection of the stern wing plates. The structure is detachable and replaceable, while simultaneously increasing strength and preventing stress concentration that could cause weld tearing, thus enhancing safety.

[0023] The second component includes a first plate 7, a first lug 8, and a second lug 9. The first lug 8 and the second lug 9 are respectively welded to the first plate 7. In this structure, the first lug 8 and the second lug 9 are arranged in parallel and welded to the first plate 7. Through holes are provided on both the first lug 8 and the second lug 9. The stern wing plate 12 is located between the first lug 8 and the second lug 9 during connection, and a pin passes through the through holes in both lugs to ensure a reliable connection.

[0024] The first plate 7 of the second component has multiple openings, and each fastening bolt 10 passes through the corresponding opening and is screwed into the screw hole on the fifth plate 5 of the first component. This structure, with fastening bolts positioned in different locations, effectively secures the first plate 7 of the second component.

[0025] The first component, first plate 1, first component second plate 2, first component third plate 3, and first component fourth plate 4 are each provided with a bent edge 14 at one end of the connecting frame 13. Each bent edge 14 is provided with multiple oblong holes 15. In the above structure, the bent edge and the corresponding plate are an integral structure or a welded structure, and are then used for fixed connection with the frame. The frame connection holes provided on each bent edge 14 are oblong holes 15. By designing the frame connection holes as oblong holes, machining errors can be eliminated, ensuring that the stern vane bracket can be smoothly installed on the frame.

[0026] The stern wing plate 12 is movably connected to the second component's first lug plate 8 and second component's second lug plate 9 via a pin 11. In this structure, the pin ensures that the stern wing plate 12 is movably connected to the second component's first lug plate 8 and second component's second lug plate 9, and that the stern wing plate 12 can only rotate relative to the pin, without disengaging from the lug plate or moving axially, thus ensuring reliable positioning.

[0027] The adjacent sides of the first component's first plate 1, second plate 2, third plate 3, and fourth plate 4 are welded together. The front ends of the first component's first plate 1, second plate 2, third plate 3, and fourth plate 4 are respectively welded to the first component's fifth plate 5. This structure, through welding, ensures the reliable connection of the corresponding plates and guarantees the overall strength of the connecting bracket.

[0028] A limiting block 16 is provided on the first plate 7 of the second component of the second component. The limiting block 16 is located between the first ear plate 8 and the second ear plate 9 of the second component. The outer side of the limiting block 16 is a limiting block inclined surface 17 that protrudes outward from the bottom. The limiting block restricts the swing position of the stern wing 12.

[0029] The thicknesses of the first component's first plate 1, second plate 2, third plate 3, fourth plate 4, and fifth plate 5 are between 5mm and 7mm; the thicknesses of the second component's first plate 7, first ear plate 8, and second ear plate 9 are between 7mm and 10mm. The thickness of the limiting block 16 is between 26mm and 34mm. This structure, by controlling the thickness of different plates, satisfies strength requirements while avoiding material waste.

[0030] The amphibious vehicle stern wing connecting bracket of this utility model comprises a first component and a second component. The first component includes a first plate 1, a second plate 2, a third plate 3, a fourth plate 4, and a fifth plate 5, which are welded together to form an integral first component. The first component is connected to the vehicle frame 13 at the rear for fixed connection. The fifth plate 5 is located at the front, and the second component is connected to the fifth plate 5 for connection. The stern wing 12 is connected to the second component for reliable connection. Through the above improvements, a distributed component structure is formed, which is then assembled to form a bracket structure for connecting the stern wing 12. The component connection is conveniently and reliably achieved by fastening bolts 10, while the stern wing 12 is movably connected, ensuring reliable connection and flexible movement. The distributed component structure improves the bracket strength, avoids stress concentration and weld tearing, and enhances safety.
