참고로 설명의 편의와 빠른 이해를 위하여 도 1, 도 2 및 도 3에 도시된 종래의 구성과 동일한 구성에 대해서는 동일한 참조부호로 지시한다.For reference, for the convenience and quick understanding of the description, the same components as those in the conventional configurations shown in FIGS. 1, 2 and 3 are denoted by the same reference numerals.

도 4 내지 도 5에 의하면, 본 발명에 의한 자동차의 회전시트(1)의 시트프레임 하부에 좌우측에 회전손잡이가 구비된 사각판(3-1)이 상측에 부설된 상부 턴테이블(3)의 상부가 볼트 등의 체결수단에 의해 고정된다.4 to 5, the upper part of the upper turntable (3) having a square plate (3-1) having a rotary knob on the left and right sides on the lower side of the seat frame of the rotating seat (1) of the vehicle according to the present invention Is fixed by a fastening means such as a bolt.

상기 상부 턴테이블(3)의 하부는 전류를 통해야만 자화(磁化)되는 자석인 전자석으로 구성되며, 전체형상은 중공원주형상이고 하단부는 일정깊이로 다수의 '∪' 형상으로 홈(14)이 절삭가공된다.The lower part of the upper turntable 3 is composed of an electromagnet, which is a magnet that magnetizes only through electric current. The entire shape is a hollow park shape, and the lower part has a predetermined depth and the grooves 14 are cut into a plurality of '∪' shapes. Processed.

상기 상부 턴테이블(3)의 내주연에는 '┏┛┗┓' 형상으로 형성된 하부 턴테이블(5)의 중앙부에 형성된 회전가이드(11)가 회전가능하게 삽입된다.At the inner circumference of the upper turntable 3, a rotation guide 11 formed at the center of the lower turntable 5 formed in a '┏┛┗┓' shape is rotatably inserted.

상기 하부 턴테이블(5)은 상부 턴테이블(3)과 동일한 전자석으로 구성되며 상부 턴테이블(3)과 접촉되는 절곡부분에 일정깊이로 다수의 '∪' 형상으로 절삭가공된 홈(14)에 기어결합되고 하부에는 시트브래킷(2)이 볼트 등의 체결수단에 의해 체결된다.The lower turntable 5 is composed of the same electromagnet as the upper turntable 3 and is gear-coupled to the grooves 14 which are cut into a plurality of '∪' shapes at a predetermined depth in contact with the upper turntable 3. In the lower portion, the seat bracket 2 is fastened by fastening means such as a bolt.

또한 상기 상부 턴테이블(3) 및 하부 턴테이블(5)의 일측 각각에는 전자석에 전류를 공급하는 전류공급부(12)가 부설된다.In addition, the current supply unit 12 for supplying a current to the electromagnet is provided on each side of the upper turntable 3 and the lower turntable 5.

이러한 구성으로 이루어진 본 발명은 다음과 같이 작동된다.The present invention made up of such a configuration works as follows.

탑승자가 회전시트(1)에 착석한 상태에서 다양한 회전각도로 이 회전시트(1)를 회전시킬 경우, 우선 상부 턴테이블(3) 및 하부 턴테이블(5)에 부설되어 있는 전류공급부(12)에 전류공급을 개폐하는 스위치(미도시)를 온(ON) 상태로 하면 같은 극의 전류가 흐르게 되어 상기 상부 턴테이블(3) 및 하부 턴테이블(5)을 구성하고 있는 전자석에 척력이 작용하게 된다.When the occupant rotates the rotary seat 1 at various rotation angles while seated on the rotary seat 1, first, a current is supplied to the current supply unit 12 installed on the upper turntable 3 and the lower turntable 5. When the switch (not shown) for opening and closing the supply is turned ON, the same pole current flows, and the repulsive force acts on the electromagnets constituting the upper turntable 3 and the lower turntable 5.

이렇게 척력이 작용하게 되면 상기 상부 턴테이블(3)이 하부 턴테이블(5)의 회전가이드(11)를 따라 상측으로 자기부양하게 되며 이때 착석자가 부양된 상부 턴테이블(3) 좌우측에 부설된 회전손잡이(13)를 잡고 회전력을 주게되면 부양된 상부 턴테이블(3)은 회전가이드(11)의 외주면을 따라서 마찰력이 전혀없이 회전하게 된다.When the repulsive force acts as described above, the upper turntable 3 self-floats upward along the rotation guide 11 of the lower turntable 5, and at this time, the rotary knob 13 placed on the left and right sides of the upper turntable 3 in which the seated person is supported. The upper turntable 3, which is supported by the rotational force, is rotated along the outer circumferential surface of the rotation guide 11 without any friction force.

이후, 착석자가 원하는 각도만큼 상부 턴테이블(3)을 회전시킨 후에 상기 스위치를 오프(OFF) 시키면 척력에 의해 부양상태로 있던 상부 턴테이블(3)이 하강하여 안착되며, 동시에 기어결합되어 원하는 위치에 견고하게 고정된다.Thereafter, when the seated person rotates the upper turntable 3 by a desired angle and then turns off the switch, the upper turntable 3, which is in a floating state by repulsion, is lowered and seated, and at the same time, the gear is firmly coupled to a desired position. Is fixed.

이상에서 상세히 설명한 바와 같이, 본 발명은 상부 턴테이블과 하부 턴테이블 사이에 발생되는 척력에 의해 회전시트가 자기부양한 상태에서 회전하기 때문에 회전시 조작력이 극히 적게들며, 원하는 각도로 조절이 용이함은 물론 부품수의 감소로 인하여 생산원가를 절감할 수 있는 효과를 제공한다.As described in detail above, in the present invention, since the rotating sheet rotates in a self-suspended state by the repulsive force generated between the upper turntable and the lower turntable, the operation force is very low during rotation, and the adjustment is possible at the desired angle. The reduction of the number provides the effect of reducing the production cost.
