Description

Technical Field

[0001] This application relates to the field of amphibious vehicle technology, specifically to a steering power system for an amphibious vehicle. Background Technology

[0002] Amphibious vehicles, also known as water-based vehicles, are a type of transportation capable of operating both on land and in water. Their design allows them to navigate in two distinct environments, moving like a regular vehicle on roads and sailing like a boat in water.

[0003] Common amphibious vehicles use a propeller at the rear to generate power to move through water. Their steering in water shares the same steering mechanism as on land, meaning they control their direction of travel in water by turning the steering wheel.

[0004] However, this structure has a small steering angle and a large turning radius when used in water, making it unsuitable for narrow waters. Furthermore, the lack of a turning angle display makes it difficult for operators to control the direction in the water, increasing the risk of accidents. Additionally, the steering mechanism is far from the power mechanism, making the installation process cumbersome and prone to malfunction. Utility Model Content

[0005] Therefore, this application provides a steering power system for an amphibious vehicle to solve the problems of large turning radius, difficulty in controlling direction in water, and cumbersome installation and easy failure of the two sets of mechanisms in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A steering power system for an amphibious vehicle includes a rudder and a propeller located under the vehicle body. A power take-off (PTO) is also installed at the bottom of the vehicle body. The propeller is connected to the PTO in a transmission manner. The rudder is located behind the propeller and has a gap between it and the propeller. The rudder can rotate relative to the vehicle body. The rotation of the rudder changes the angle between it and the plane of rotation of the propeller.

[0008] Optionally, a mounting plate is fixed to the bottom of the vehicle body, and a shaft is mounted on the bottom of the mounting plate. The shaft is rotatably connected to the mounting plate; the propeller is fixed to the shaft and can rotate with the shaft.

[0009] Optionally, the shaft is perpendicular to the axis of the propeller.

[0010] Optionally, the shaft is positioned on the side of the propeller rudder closest to the propeller.

[0011] Optionally, the shaft is positioned corresponding to the extended axis of the propeller.

[0012] Optionally, a central control panel is provided inside the vehicle body, and the central control panel is equipped with an operating handle for controlling the rotation of the propeller rudder and a switch for starting and stopping the propeller.

[0013] Optionally, the thickness of the propeller gradually decreases from the shaft to both ends.

[0014] Optionally, the distance between the rudder and the propeller is 5 cm.

[0015] Optionally, the rotation angle of the propeller is in the range of 0-35°.

[0016] Optionally, the central control panel is also equipped with an angle gauge, which is used to display the rotation angle of the propeller.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. The rudder is mounted directly behind the propeller. By rotating the rudder, the direction of water flow is changed, thus achieving a small-radius turn. This close-proximity installation of the propeller and rudder integrates the power system and steering mechanism into one unit, making installation more convenient, reducing unnecessary wiring and piping, and decreasing the likelihood of malfunctions.

[0019] 2. The thickness at both ends of the propeller is small, which can effectively reduce the water resistance.

[0020] 3. The steering system is no longer operated by the steering wheel, but by the control lever on the dashboard, making driving easier.

[0021] 4. The operating handle and switch are both located on the central control panel, making operation more convenient.

[0022] 5. The angle gauge makes it easier for the driver to control the direction of rotation in the water. Attached Figure Description

It should be understood that the specific shapes and structures shown in the drawings should not generally be regarded as limiting conditions for implementing this application; for example, based on the technical concept disclosed in this application and the exemplary drawings, those skilled in the art are able to easily make conventional adjustments or further optimizations to the addition / reduction / classification, specific shapes, positional relationships, connection methods, size ratios, etc. of certain units (components).

[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0032] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0033] A steering power system for an amphibious vehicle. (See reference) Figures 1-4 The driver's cab is located at the front of the vehicle body, while the passenger area is at the rear. A propeller 1, a propeller 2, and a power take-off (PTO) 3 are located on the lower rear side of the vehicle body. The propeller 2 is connected to the PTO 3 and provides power for the vehicle to move in water. A switch is located in the driver's cab to control the operation of the propeller 2.

[0034] The propeller 1 replaces the original steering wheel and is positioned directly behind the propeller 2, with a certain gap between them. Specifically, a mounting plate 4 is fixed to the bottom of the vehicle body, and a shaft 5 is mounted on the bottom of the mounting plate 4, rotatably connected to the mounting plate 4. Correspondingly, an operating handle is provided in the driver's cab. This operating handle is used to control the rotation direction and angle of the propeller 1. By controlling the operating handle, the driver can more intuitively and precisely adjust the angle of the propeller 1, thereby more accurately controlling the rotation direction and angle of the vehicle body.

[0035] To make it easier for the driver to operate, the aforementioned switches and control handles are all located on the center console panel in the driver's cab.

[0036] Furthermore, the shaft 5 is perpendicular to the axis of the propeller 2 and corresponds to the position of the extension line of the axis of the propeller 2, that is, the extension line of the axis of the propeller 2 can intersect with the shaft 5.

[0037] In this embodiment, the propeller 1 is a rectangular plate-like structure. The propeller 1 is vertically fixed to the shaft 5 and can rotate with the shaft 5, allowing the propeller 1 to rotate relative to the vehicle body and the propeller 2. The rotation of the propeller 1 changes the angle between itself and the rotational plane of the propeller 2. When the propeller 1 deflects at a certain angle, the speed of the water flowing over both sides of the propeller 1 will be inconsistent, resulting in a pressure difference between the two sides. This pressure difference creates a lateral force, propelling the hull to turn to one side, achieving a small-radius turn.

[0038] The shaft 5 is positioned on the side of the rudder 1 closer to the propeller 2 rather than in the middle, so that the distance between the end face of the rudder 1 on the side closer to the propeller 2 and the shaft 5 is smaller than the distance between the other side of the rudder 1 and the shaft 5.

[0039] Furthermore, in order to reduce the water resistance encountered by the vehicle body during driving, the thickness of the propeller 1 gradually decreases from the shaft 5 to the front and rear ends, which improves steering performance without affecting the driving performance of the vehicle body itself.

[0040] In this embodiment, the unilateral swing angle range of the propeller 1 is 0-35°. To facilitate the control of the rotation angle of the propeller 1, an angle table (not shown in the figure) can also be set on the central control panel. This angle table is used to intuitively display the current rotation direction and corresponding rotation angle of the propeller 1.

[0041] The distance between the end face of the rudder 1 near the propeller 2 and the propeller 2 is 5cm.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
