본 발명은 하지 장애인들의 이동수단중 한가지인 전동모터가 장치된 휠체어에 관한 것으로, 상세하게는 휠체어에 장착된 네개의 원형바퀴중 두개의 바퀴에 전동모터가 부착되어 밧데리의 전원으로서 모터를 회전시키므로 운행되었던 지금까지의 방법에서, 전차(戰車)를 축소시킨 형태로서 도 3과 같이 여섯부분의 체인기어(18) (18-1)에 의한 무한궤도식(Caterpillar)이며 고무벨트바퀴(11) 가운데 홈의 체인(12)에 접합되어 가이드 후레임(16)에 따라 베어링(14)이 미끌어지듯 이동하므로서 휠체어가 운행되도록 한것이며 바닥의 요철이 심한곳과 원형바퀴로는 넘지못하던 장애물과 일반 계단까지도 자유로이 오르내리며 운행하도록 한것에 관한것이다.The present invention relates to a wheelchair equipped with an electric motor, which is one of the handicapped people of the lower limbs, and in detail, an electric motor is attached to two wheels of four circular wheels mounted on the wheelchair to rotate the motor as a power source of the battery. In the conventional method that has been operated, the tank is reduced in size, and is caterpillar by the six-part chain gear 18 (18-1) as shown in FIG. It is joined to the chain 12 of the groove, so that the bearing 14 moves along the guide frame 16 so as to slide, and the wheelchair is operated. It's about going up and down.

종래의 휠체어에는 직경이 30cm이내의 원형바퀴로 구성되므로 낮은 장애물도 넘지 못하였고 바닥에 닿는 면이 적으므로 충분한 동력이 전달되지 않아 제힘을 발휘하지 못하였으며, 자갈밭, 모래밭, 요철이 많은 곳에서는 운행이 어려웠으며, 요철로 인한 충격이 모두 운전자에게 전달되어 피곤할수밖에 없었다.Conventional wheelchairs consist of circular wheels with a diameter of 30 cm or less, so they do not exceed low obstacles and have a small surface contacting the floor, so they are not able to exert sufficient power due to insufficient power transmission. This was difficult, and all the shocks caused by the irregularities were transmitted to the driver, which forced him to be tired.

일반적인 전동 휠체어는 등판각 12°이내이며 시트의 변환각도 12°로 설계되고 등받이를 90°∼120°정도까지 변화시킬수 있으나 수동 변환 시스템이기에 경사가 일정치 않은 곳에서는 위험한 운행이 될수 있으며, 작은 변화에도 반드시 타인의 도움이 있어야만 운행이 가능한 문제가 있다.The general electric wheelchair is within 12 ° of the back angle, and the conversion angle of the seat is designed to 12 °, and the backrest can be changed by 90 ° ~ 120 °. However, because it is a manual conversion system, it can be a dangerous operation in the place where the slope is not constant. Even with the help of others there is a problem that can be operated.

본 발명은 상기와 같은 문제를 해소하기위해 도 1의 사시도에서 (가)와 (나)와 같이 두개의 바퀴가 무한궤도식(Caterpillar) 형태이며, 도 1의 (라)부분과 같이 바퀴 하단부 중앙에 반원형의 홈(Semicircular groove)이 있어서 도 12에서와 같이 계단의 최상단부에 도착했을때 전면부가 급작스레 내려앉는 충격이 없으며, 반대로 내려올때도 계단 최상단부 끝에서 전면이 급작스레 내려가 운전자에게 충격을 주는 일이 없이 안전하게 운행하며, 경사진 계단등에서 발생되는 시트의 경사각도도 도 3의 시트지지대(20)에 고정되어 있는 힌지(다)의 자유로운 움직임으로 도 1의 시트(41)가 경사각에 구애됨이 없이 항상 지면과 수직을 유지하게 된다.The present invention is to solve the above problems in the perspective view of Figure 1 (a) and (b) two wheels are caterpillar (Caterpillar) form, as shown in the (d) part of Figure 1 in the center of the wheel. Since there is a semicircular groove, the front part suddenly drops when reaching the top of the stairs as shown in FIG. 12, and the front part suddenly descends from the top end of the stairs even when descending to give the driver an impact. Safely running without, the inclination angle of the seat generated from the inclined stairs, etc. The free movement of the hinge (c) fixed to the seat support 20 of FIG. It will always be perpendicular to the ground.

시트(41)에 운전자가 앉았을때 시트 전체의 무게가 도 1의 힌지(다)에 걸리며, 시트(41)하단에 있는 밧데리의 무게로 인해 시트와 운전자까지 합한 무게의 삼분의 이 이상이 힌지(다)의 최하단부에 있게 되므로 시트에 앉은 운전자는 도 8의 평지에서와, 도 9의 계단을 오를때, 도 10의 계단을 내려올때, 계단경사에 구애없이 항상 수직적인 자세로 운전하게 되며, 도 1의 콘트롤러(42)는 시트(41)에 부착되어 운전자와 같이 같은 위치에서 작동되므로 경사각에 관계없이 안전하게 운전할수 있다.When the driver sits on the seat 41, the entire seat weight is held on the hinge C of FIG. 1, and more than two-thirds of the total weight between the seat and the driver is hinged due to the weight of the battery under the seat 41. The driver sitting on the seat will always drive in a vertical position, regardless of the inclination of the stairs, when climbing the stairs of Figure 8, when climbing the stairs of Figure 9, descending the stairs of Figure 10, The controller 42 of 1 is attached to the seat 41 and operated at the same position as the driver so that the controller 42 can safely drive regardless of the inclination angle.

바퀴가 무한궤도식 벨트타입으로 되어있어 지면에 닿는 면이 많으므로 요철이 많은 지형에서도 요철로 인한 흔들림이 적으며, 모래밭과 같이 무른 지면에서도 운행할수 있다.Since the wheels are of the caterpillar type belt type, the surface touches a lot of the surface, so there is little shaking due to the irregularities in the terrain with a lot of irregularities, and it can operate on the soft ground such as the sand.

특히 지면에 닿는 면의 중심부에 도 1의 (라)부분처럼 반원형의 홈(Semicircular groove)이 있어서 계단이동시 발생되는 충격을 없게 한것에 특징이 있다.In particular, there is a semi-circular groove (Semicircular groove) in the center of the surface in contact with the ground to avoid the impact generated when moving the stairs.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

본 발명은 전차(戰車)를 축소시킨 형태와 같이 도 1의 (가)와 (나) 한쌍의 무한궤도식(Caterpillar)형태로 구성되며, 도 3에서와 같이 각각 여섯개의 체인기어(18) (18-1)가 배치되어, 그중 주동측 체인기어(18) 두곳과 피동측 체인기어(18-1) 네곳으로 되어있으며, 전면부의 주동측 체인기어(18) 한곳과 피동측 체인기어(18-1) 두곳, 후면부의 주동측 체인기어(18) 한곳과 피동측 체인기어(18-1) 두곳이 각각 체인(12)으로 연결되어 한방향으로 회전하도록 되었다. 도 2의 네개의 전동모터(19)와 연결된 주동측 체인기어(18)가 발생하는 동력을 무한궤도식 벨트타입의 바퀴(11)에 분배하여 고루 전달케하였고, 도 4와 도 5의 베어링 가이드 후레임(16)이 도 3의 여섯 개 체인기어(18) (18-1)가 연결된 형태로 구성되며, 도 4와 도 5에서와 같이 벨트타입의 바퀴(11)와 체인(12)이 체인고정핀(17)으로 고정케되며, 도 4, 도 5, 도 7에서 베어링 가이드 후레임(16)의 내부에 고정되어 회전하는 원통 베아링(13)이 벨트타입 바퀴(11)을 바쳐주며, 후레임(16)의 외부 양옆에 가이드 베아링(14)과 벨트타입 바퀴(11)을 삼각형 후레임(15)으로 고정시켜 가이드 후레임(16)에서 미끌어지며 작동케하였다. 도 3의 체인기어(18) (18-1)가 있는 부분의 후레임(16)은 도 4와 도 6과 같이 홈이 파여져서 체인기어(18) (18-1)와 체인(12)가 맛물려 회전하는데 문제가 없이 하여 벨트타입의 바퀴(11)가 가이드 후레임(16)을 따라 바퀴부분의 전체외각을 돌며 미끌어지듯 이동케하는 방법이다. 특이한것은 도 1의 (라)부분처럼 바닥에 닿는 면의 중심부에 반원형의 홈(Semicircular groove)을 설치하므로 도 12에서와 같이 운행할때 계단끝 모서리가 홈에 들어가면서 가이드 후레임(16)의 모양에 따라 곡선으로 미끌어져 이동하므로 경사지에서 평지로 부드럽게 진입할수 있다.The present invention is composed of a pair of caterpillar forms of (a) and (b) of FIG. 1 as shown in the form of a miniature tank, and each of six chain gears 18 ( 18-1) are arranged, including two main chain gears 18 and four driven chain gears 18-1, one main chain gear 18 of the front part and the driven chain gears 18-. 1) Two places, one driving side chain gear (18) of the rear portion and two driving side chain gear (18-1) are connected to each of the chain 12 to rotate in one direction. The power generated by the main chain gear 18 connected to the four electric motors 19 of FIG. 2 is distributed evenly to the wheel 11 of the crawler belt type, and the bearing guide frame of FIGS. 4 and 5 is evenly transmitted. 16 is composed of six chain gears 18 and 18-1 of FIG. 3 connected to each other, and the belt-type wheel 11 and the chain 12 of the belt-type fixing pin as shown in FIGS. 4 and 5. 4, 5, and 7 is fixed to the inside of the bearing guide frame 16 is fixed to the rotating cylindrical bearing (13) to dedicate the belt-type wheel (11), frame 16 Guide bearings 14 and belt-type wheels 11 on both sides of the outer side were fixed with a triangular frame 15 to slide and operate at the guide frame 16. The frame 16 of the part with the chain gear 18 (18-1) of FIG. 3 is grooved like FIG. 4 and FIG. 6, and the chain gear 18 (18-1) and the chain 12 taste. The belt-type wheel 11 is rotated along the guide frame 16 so as to slide the entire outer shell of the wheel part without slipping and rotating. What is unusual is that the semicircular groove is installed at the center of the surface touching the floor as shown in (D) of FIG. 1 so that the edge of the staircase enters the groove when driving as shown in FIG. It slides along the curve, so you can smoothly enter the flat from the slope.

도 2와 도 3의 전면모터커버(23)와 후면모터커버(22)가 도 2의 (가)와 (나)부분을 연결 고정하여 한몸체로 이루며, 도 1과 도 3의 시트지지대(20)의 힌지(다)에 시트(41)와 운전자 몸무게 총합계의 중심선이 지나며, 힌지(다)에 고정된 시트(41)가 회전할 수 있으므로 등판각에 구애됨없이 수직을 유지할수 있고, 운전자와 시트(41)를 합한 무게의 삼분의이 이상이 밧데리 무게로인하여 시트(41)하단에 집중되므로 오뚜기와 같이 경사지에서도 시트에 앉아있는 운전자는 힌지(다)로 인해 항상 수직선상에 있게 되며, 콘트롤러(42)는 시트에 고정되어 있으므로 도 8의 수평운전일때와, 도 9의 계단을 오를때, 도 10의 계단을 내려올때도, 운전자는 수직을 유지하며 항상 같은 자세에서 운전에 집중하게 한다.The front motor cover 23 and the rear motor cover 22 of FIGS. 2 and 3 connect and fix the parts (a) and (b) of FIG. 2 to form a single body, and the seat support 20 of FIGS. The center line of the seat 41 and the total weight of the driver passes through the hinge (c) of the driver, and the seat 41 fixed to the hinge (c) can rotate, so that it can be maintained vertically regardless of the back angle, and the driver and the seat More than two-thirds of the combined weight (41) is concentrated at the bottom of the seat (41) due to the weight of the battery, so that the driver sitting on the seat at an incline, such as a squid, will always be on a vertical line due to the hinge (c). ) Is fixed to the seat so that the driver stays vertical and always concentrates on driving in the same posture when the horizontal driving of FIG. 8, the climbing of the stairs of FIG. 9, and the lowering of the stairs of FIG. 10 are performed.

이상에서 상술한 바와같이 본 발명은 무한궤도식(Caterpillar)의 형태로, 벨트타입의 바퀴를 사용하므로서, 지면에 닿는 면이 많으므로, 요철이 심한 도로나 모래처럼 파여지기쉬운 도로에서도 충격없이 이동이 가능하며, 계단의 모서리를 이용하여 경사면이동과 같은 효과로 계단을 자유로이 오르내릴수 있으며, 바닥에 닿는면 중앙부에 본 발명의 특징인 반원형의 홈(Semicircular groove)을 두어 계단상단 끝모서리에서 발생되는 급작스런 충격을 부드럽게 흡수하게 하였으며 운전자와 시트의 합한 무게중심이 시트 하단부에 있으므로 시트가 힌지(다)에 의해 전·후로 회전하도록 설치하므로서 인위적인 변환없이 운전자는 항상 수직선상에 있게 되며 콘트롤러도 시트에 부착되어 같이 움직이므로 경사각에 구애됨없이 안전한 자세로 운전하도록 한것이다.As described above, the present invention uses a belt-type wheel in the form of a caterpillar, so that many surfaces touch the ground, so that the movement can be performed without impact even on a road with a rough unevenness or a road that is easy to be dug like sand. It is possible to use the edge of the stairs to move up and down the stairs freely by the same effect as moving the slope, and a semicircular groove, which is a characteristic of the present invention, is placed in the center when it touches the floor. The shock absorber is smoothly absorbed and the center of gravity of the driver and the seat is located at the bottom of the seat, so the seat is rotated forward and backward by the hinge (c) so that the driver is always on the vertical line without artificial conversion and the controller is attached to the seat. As they move together, they are driven in a safe posture without regard to the angle of inclination.
