Abstract:
An apparatus for shifting the center of gravity of a vehicle having three wheels or more is provided. The apparatus includes: a movable frame having a certain shape and movably fixed, at one side, to a vehicle body in such a manner that a portion or all of the frame is movable to the left/right side relative to the driving direction of the vehicle body; and a control unit for controlling the left/right movement of the frame to shift the center of gravity of the vehicle body as needed, the control unit including: a cylindrical rotation body in which a portion of the inside thereof including the center of rotation is open; a rotation bar coaxially coupled to the center of rotation of the rotation body to rotate with the rotation body along with the rotation of the rotation body; a first link member rotatably coupled, at its one end, to the rotation bar included inside the rotation body; and second link members crossed each other, each second link member having opposite ends wherein one end is rotatably coupled to the other end of the first link member, and the other end is rotatably coupled to the upper portion of the frame, whereby the center of gravity is shifted and restored more easily, effectively, and precisely, and upon stopping, the movement of the vehicle body is precisely controlled.
Abstract:
An apparatus for shifting the center of gravity for use in a vehicle having three wheels or more, and a lozenge- shaped automobile having the same are provided. The apparatus comprises a stationary chassis, a movable chassis, and a gear device for moving the movable chassis relative to the stationary chassis. The stationary chassis is disposed perpendicular to the forward direction of the automobile, and has a stationary rail. The stationary rail is formed in a circular shape having, as the origin, a point on the line projected on the ground from the longitudinal center line of the car body parallel to the forward direction of the automobile. The movable chassis is disposed parallelto the forward direction of the automobile, and has a moving rail engaged with the stationary rail so as to move therealong. The moving rail moves to the left/right relative to the forward direction along the stationary rail. A moving gear is installed on the movable chassis parallel to the moving rail. A rotating gear is installed on the stationary chassis so as to be engaged with the moving gear. A ball screw device is installed so as to be engaged with the rotating gear. The lozenge- shaped automobile having the above construction includes a steering unit for simultaneously steering three front wheels in the forward direction of the automobile.
Abstract:
A tidal current power generator according to one embodiment of the present invention comprises: a generator column; an impeller-type rotating blade arranged on top of the generator column; and a first sealed chamber with a bottom portion having a lower inlet into which a rotating shaft of the impeller-type rotating blade is vertically introduced, and an interior in which an impeller-type generator with a vertical shaft is disposed to generate electrical energy from the rotating motion of the rotating shaft of the impeller-type rotating blade.
Abstract:
Disclosed is a separate type nursing bottle, which includes two separate bodies so as to allow a user to cleanly wash the bodies in a convenient manner. The separate type nursing bottle includes an upper body, a lower body, and a connector. The upper body has a pipe-shape and includes screw parts formed at an outer circumferential surface of one end of the upper body and at an outer circumferential surface spaced a predetermined distance from another end of the upper body, respectively. The lower body has a bowl-shape, has an open side engaged with an outer circumferential periphery of the other end of the upper body, and includes a locking jaw formed along an outer circumferential periphery of one end of the open side. The connector has a pipe- shape, has a locking jaw so as to allow the connector to be assembled with an outer side of the upper body while one end of the connector is locked in the locking jaw of the lower body, and also has a screw part engaged with the screw part of the another end of the upper body. The upper body from the screw part to the other end is slanted toward a central axis of the upper body so that an inner diameter is smaller toward the other end. The lower body is made from material, which is more flexible than material of the upper body, so as to allow a shape of the lower body to be easily changed. As a result, there is a sanitary advantage in that the user can cleanly wash the interior of the nursing bottle, and convenience can be provided to the user while washing the bottle.

Abstract:
Disclosed is an apparatus for shifting the center of gravity of a vehicle having three wheels or more, which includes: a fixed chassis part on which at least one fixed rail part shaped like a circular arc having its origin at one point on a virtual line obtained by projecting the vertical center line of the vehicle body on the ground is included; a movable chassis part in which at least one movable rail part movably assembled in the left/right direction relative to the vertical direction of the vehicle body along the fixed rail part is included; and a control unit for shifting the center of gravity of the vehicle body so as to shift the center of gravity of the vehicle body as needed by controlling a shift of the movable rail part of the movable chassis part relative to the fixed rail part of the fixed chassis part. According to the apparatus for shifting the center of gravity of a vehicle having three wheels or more requiring the shifting of the center of gravity to the left/right relative to the driving direction, upon driving of the vehicle, the center of gravity is shifted and restored more easily, effectively, and precisely, and upon stopping, the left/right movement is precisely controlled. In addition, the apparatus can prevent a tire thereof from wearing and secure safe driving.
