For example, such a door portion can open or close only the lower surface of the storage portion, or open or close the front surface of the storage portion. Therefore, when the storage portion is opened, the wheel and the coupling portion 180 can be moved to the closed position when the wheel and the coupling portion 180 move to the open position and the storage portion is closed. Here, the open position means a position at which the wheel and coupling portion 180 can be exposed to the outside (that is, the bottom and the bottom of the bottom) of the hull 100 for on-land travel, as shown in Fig. Further, the closed position means a position where the wheel and coupling portion 180 can be stored inside the hull 110 for water running.

In one aspect of the present invention, the side plate 190 may be located at a portion of the hull side portion 120 to allow such wheels and fasteners to be disconnected from the outside when the wheels and fasteners are moved to the closed position. The one portion may refer to a position corresponding to the position of the wheel. This side plate 190 may be located at the position of the side portion 120 corresponding to the position of the rear wheel 175.

The amphibious boat according to an aspect of the present invention improves on-the-road running safety by fundamentally eliminating the contact of the bottom of the hull 110 with the ground when the wheel is opened and exposed to the outside, It can be allowed to be smooth. For example, when the wheel is in the open position, the size of the coupling portion 180 and the wheel can be determined so that the wheel can have a minimum ground clearance of 250 mm or more and 300 mm or less at the center of the ship. Further, when the wheel is opened and exposed to the outside, the fastening portion 180 can be fixed so as to be mechanically supported separately from the support by the hydraulic pressure.

FIG. 2 is a perspective view of the bottom 210 of the amphibian boat 100 according to an embodiment of the present invention.

2, the amphibian boat 100 according to one aspect of the present invention includes a front wheel 170, a front wheel coupling portion 180, a rear wheel 175, a rear wheel coupling portion 185, a front wheel receiving portion 230a, a rear wheel housing portion 230b, and a sliding door 220. [

The components of the amphibian boat 100 shown in FIG. 2 are exemplary only, and additional components may be present, or some of the components of FIG. 2 may be omitted.

Although not shown in FIG. 2, when the front wheel 170 is moved to the closed position, a separate door portion may be coupled to the front wheel housing portion 230a to block contact between the front wheel 170 and water. The door portion can be opened or closed through sliding or pivotal movement.

The front wheel housing part 230a can form a storage space so that the front wheel 170 can be housed inside the hull 110 when the front wheel 170 is moved to the closed position. 2, the front wheel receiving portion 170 is formed so that the front wheel 170 is rotated 180 degrees or less around the specific axis at the open position, for example, so that the amphibious boat 100 does not directly contact the water surface when the water- A movable space can be formed. In addition, the front wheel compartment 170 may be provided with a space within the hull to accommodate the front wheel 170, even when the front wheel 170 moves 180 degrees (e.g., 270 degrees) about a specific axis in the open position have.

2, one side of the rear wheel 175 is engaged with the rear wheel coupling portion 185 and can move between the open position and the closed position integrally with the rear wheel coupling portion 185. [ When the rear wheel 175 moves to the closed position, the rear wheel 175 can be stored in the rear wheel housing portion 230b. The rear wheel housing portion 230b may have a variety of spaces such as the front wheel housing portion 230a that can accommodate the rear wheel 175. [ The rear wheel 175 and the rear wheel coupling portion 185 can be rotated within an angle range of, for example, 90 degrees to 270 degrees by the rear wheel housing portion 230b.

In one aspect of the present invention, a sliding door 220 may be provided on a part of the bottom 210 of the amphibian boat 100. The sliding door 220 can be inserted into the bottom 210 of the amphibian boat 100. Accordingly, when the wheel (for example, the rear wheel 175) is moved to the closed position, the sliding door 220 is moved to the closed position so as to cover the wheel (e.g., the rear wheel 175) (For example, the stern direction) of the main body 110. Therefore, by the extended movement of the sliding door 220, a cover operation for the lower part of the bottom 210 can be realized.

In a further aspect of the present invention, for example, when the wheel is the rear wheel 175, the sliding door 220 slides in the stern direction at a position where the sliding door 220 is inserted to cover the lower end surface of the storage portion, In addition, the additional sliding door or folding door may be moved downward in the downward direction (i.e., downward direction) at the end of the stern to cover the side surface of the receiving portion in which the rear wheel 175 is housed.

In one aspect of the present invention, the sliding door 220 may be inserted into the bottom 210 or form part of the bottom 210. As the fastening portion moves from the open position to the closed position, the fastening portion 185 and the rear wheel 175 are housed in the rear wheel housing portion 230b at a part of the bottom 210, so that a storage space can be formed. Accordingly, the sliding door 220 can slide in parallel to the stern direction or at a predetermined angle to cover one side of the storage space.

The sliding door 220 can be extended and moved through the bottom of the ship under the control of the steering movement device, so that lifting phenomenon (longitudinal movement phenomenon) of the athlete due to water movement can be alleviated. The extension length of the sliding door 220 may vary depending on the speed of the hull, the weight, the degree of longitudinal movement of the bow, and the like.

In the case of the water movement of the amphibian boat 100, the lifting of the bow may occur due to the characteristics of the boat having the streamlined hull. Due to the lifting phenomenon of such a player, there may arise a problem about stability of water running of the boat 100 (longitudinal rocking phenomenon). In addition, due to the lifting of such a bow, the air friction on the boat 100 is increased, friction on the stern portion (fresh water, seawater) and pitching of the ship cause loss of speed of the ship and loss of fuel .

The sliding door 220 according to one aspect of the present invention covers the rear wheel 175 that has moved to the closed position and also moves to the outside (that is, backward) through the transom 165 of the stern 160 It can serve as a trim tab for enhancing the stability of the water running of the hull 110. [0052] That is, when the boat 100 is accelerated during the running of the water, the boat 100 may be lifted up due to the increased drag, It can be controlled by sliding and extending from the hull.

According to one aspect of the present invention, the sliding door 220 can be operated under the control of the control device. In addition, the sliding door 220 may adaptively vary the extension length depending on the degree of elevation of the bow portion. In this case, a sensor for detecting the degree of elevation of the bow may be attached to one position of the bow of the hull 110.

In addition, the sliding door 220 can change the extension length based on the water running speed of the amphibian boat 100. Such a change in the extension length can be automatically implemented by the control device.

That is, when the sliding door 220 is extended to the outside of the hull along the aft direction in a state where the sliding door 220 is inserted into a part of the bottom, stability of the water running can be ensured because the hull is caught by the pitch.

Accordingly, the sliding movement of the sliding door 220 can open and close the wheel and the fastening portion inserted into the hull, and prevent the lifting of the bow.
