Abstract

The left-right expandable buoyancy-adjustable amphibious motorcycle according to the present invention is characterized by comprising: a main body; a pair of buoyancy pods each located on the left and right sides of the lower side of the main body while including a water jet; and a slide mechanism for expanding the buoyancy pods to the left and right. According to the left-right expandable buoyancy-adjustable amphibious motorcycle of the present invention, the amphibious motorcycle can secure stable buoyancy when driving on water through the left-right expandable buoyancy-adjustable buoyancy pod, thereby reducing the risk of overturning and improving driving stability. In addition, since the buoyancy pod can be expanded and contracted, the volume and resistance can be minimized when driving on land, thus providing the advantage of efficient driving.

Description

Amphibious Motorcycle with Lateral Expansion Buoyancy Control The present invention relates to a left-right extendable buoyancy-adjustable amphibious motorcycle, and more specifically, to an amphibious motorcycle capable of providing stability and flexibility in both land and water driving through a buoyancy pod that adjusts buoyancy while extending left and right. Amphibious motorcycles are vehicles designed to operate in both land and water environments, and are generally equipped with a buoyancy device fixed to the underside of the body to ensure buoyancy and stability on water. While these buoyancy devices provide buoyancy, their fixed structure makes it difficult to achieve the desired balance during water travel, resulting in reduced driving stability. In particular, since the position of the buoyancy device cannot be dynamically adjusted in response to waves or changes in water surface conditions, there is a risk of capsizing or loss of balance. In addition, conventional fixed buoyancy devices are designed to be bulky and protrude from the exterior of the main body, causing unnecessary air resistance and bulk during driving on land. This degrades driving performance and increases the weight and resistance felt by the driver while driving, making operation inconvenient. Furthermore, since the fixed buoyancy device remains permanently mounted on the underside of the vehicle, it has the disadvantage of occupying a large amount of space when parked or stored. Because the buoyancy devices of existing amphibious motorcycles are fixed, they cannot deliver optimal performance in both water and land driving, and they lack the ability to adjust the buoyancy device according to the situation. Therefore, there is a need to develop a novel and advanced amphibious motorcycle that provides a buoyancy control device to ensure stable buoyancy during water travel, and can enhance driving performance and stability on both land and water by expanding and contracting the device left and right as needed. FIG. 1 is a perspective view illustrating the external structure of the amphibious motorcycle of the present invention. Figure 2 is a perspective bottom view of an amphibious motorcycle. FIG. 3 is a rear view showing the buoyancy pod of an amphibious motorcycle partially extended to the left and right. FIG. 4 is a conceptual diagram illustrating the stepwise expansion state of the buoyancy pod and the operating state of the balance block and the first multi-link mechanism. FIG. 5 is a perspective conceptual diagram illustrating the state in which the second pod is extended backward by the first and second pods and the second multi-link mechanism. FIG. 6 is a block diagram illustrating the detailed configuration of an automatic steering device. Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The attached drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same components. FIG. 1 is a perspective view illustrating the external structure of the amphibious motorcycle of the present invention, and FIG. 2 is a perspective bottom view of the amphibious motorcycle. As can be seen from FIGS. 1 and FIGS. 2, the motorcycle of the present invention supports an amphibious method, as the name suggests, which can be operated on both land and water, and is based on including a main body (10), a buoyancy pod (100), and a slide mechanism (200). The main body (10) is the central structure of the motorcycle and provides a seat (or backrest) on which a driver can ride and operate the vehicle. A steering handle is located at the front of the main body (10) and is positioned to facilitate operation by the driver. In addition, the main body (10) is connected to wheels (20) at the front and rear, just like a regular motorcycle, and the frame is made of a strong and lightweight material to increase driving stability when driving on land and water. In addition, the material at this time is desirable to absorb shocks that may occur during driving and maintain safety, and a special coating may be applied to prevent corrosion and enhance durability. The lower structure of the main body (10) is designed with a low center of gravity to ensure stability during land and water driving, thereby preventing overturning during driving and enabling smooth driving. In particular, the lower part of the main body (10) is provided with a space for mounting a buoyancy pod (100) and a slide mechanism (200) that enables its expansion, which will be described later. In addition, it can be designed to integrate devices necessary for amphibious functions. Figure 3 is a rear view showing the buoyancy pod of an amphibious motorcycle partially extended to the left and right. As can be seen from FIGS. 1 to 3, the buoyancy pod (100) of the present invention is a structure that provides buoyancy to allow the motorcycle of the present invention to float on water w
