Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the elevating footrest is not fixed to the lower end of the door but is formed to move between the first position of the lower end of the door and the second position of the vehicle outer bottom side. That is, the elevator platform is repeatedly moved between the first position of the lower end of the door, which is the position at which the conventional elevator elevator is fixed, and the second position, which is moved to the inside of the vehicle in the horizontal direction and higher in the vertical direction than the first position. Is formed. While the door is closed and the car is running, the elevating scaffold is positioned at the second position on the outside bottom side of the vehicle. When the door is opened, the elevating scaffold is driven by electric force to move to the first position of the lower end of the door.

That is, when the door is closed, the elevating scaffold located at the lower end of the door is moved horizontally while being pulled toward the vehicle side, and at the same time, the vertical scaffold is moved upward to the second position on the outer side of the vehicle. By forming high, it is possible to solve the problem that the vehicle body is substantially lowered due to the elevating scaffold.

To this end, the present invention is to detect the opening and closing of the door by the sensor device to control the movement of the elevator foot as the door is opened and closed, of course.

The present invention has a structure as shown in Figs. 1 and 2 so that the elevator foot is effectively moved between the first position and the second position which is higher than the first position and at the same time located further inside the vehicle.

That is, the present invention is very simple and efficient to configure the vertical and horizontal simultaneous movement of the lifting step by the two X-arms. To this end, the upper X-arm 102 installed in the vertical direction and the lower X-arm 110 which are coupled to the lower side of the upper X-arm and expand or fold in conjunction with the upper X-arm are installed. The upper x-arm and the lower x-arm will of course have two arm ends on each side. Each end of the arm is coupled to the sewing port so that it is connected to the guide rod by the sewing port, and each X-arm is formed to perform the movement of regularly expanding or folding along the guide rod.

First, two rod mounting holes 104 coupled to the upper end of the upper X-arm installed vertically are respectively coupled to the driving side guide rods 100. The sealing opening 104 is preferably formed to be movable while sliding along the rod by having a ring-shaped rod mounting structure through which the rod penetrates as shown. The driving side guide bar 100 is formed so that the position is fixed with respect to the vehicle body bottom side. To this end, a driving side guide rod is fixedly coupled to one side of the mounting member 101 which is coupled to and fixed to the vehicle body frame, and the mounting member 101 may be coupled to and fixed to the vehicle body using bolts or the like.

Two sewing holes 106 coupled to the lower end of the upper x-arm 102 are respectively coupled to the intermediate guide rod 108 and move along the intermediate guide rod. By this configuration, when the upper X-arm is unfolded, the middle guide rod is moved downward, and when the upper X-arm is folded, the middle guide rod is moved upward. 3 and 4 show a perspective perspective view of the expanded state. In the present specification, when the sewing spheres on one side of the X-arm are close to each other, the X-arms are spread out, and when the sewing spheres on the side of the X-arm are far from each other, the X-arms are folded. Meanwhile, two rod mounting holes 106 coupled to the lower end of the upper x-arm are respectively coupled to one end of the lower x-arm 110 installed in the horizontal direction as shown. The other end of the lower x-arm is coupled to the scaffold guide rod 122 as shown. Therefore, when the upper x-arms are unfolded or folded, the lower x-arms are also linked and unfolded or folded. Scaffold guide rod 122 is fixedly coupled to the elevating scaffold (120). Therefore, when the scaffolding guide rod is moved, the elevating scaffold is moved together.

As such, the lower X-arm, the middle guide rod, and the scaffold guide rod are moved by interlocking with the upper X-arm by the structure formed of two X-arms and three guide rods coupled thereto. That is, as shown in FIG. 3 or FIG. 4, when the upper X-arm is unfolded, the middle guide rod is moved downward, and at the same time, the lower X-arm is unfolded while the scaffold guide rod is horizontally moved toward the vehicle side. That is, the scaffolding guide rod is moved vertically and horizontally. Meanwhile, when the upper x-arm is folded as shown in FIG. 1 or 2, the middle guide rod 108 is moved upwards while the lower x-arm is folded, and the scaffold guide rod 122 is moved upward. It moves horizontally inside the vehicle. The elevating scaffold 120 which is fixed to the scaffold guide rod 122 and moved together by this structure is to simultaneously move horizontally and vertically between the first position and the second position. That is, while driving, as shown in FIG. 1 or FIG. 2, when the upper X-arm and the lower X-arm are folded, the elevator foot is in the second position on the outside bottom side of the vehicle and the door is opened to get on and off the vehicle. As shown in FIG. 4, the upper x-arm and the lower x-arm are unfolded so that the elevator foot is in the first position at the bottom of the door.

One of the sewing holes 104 coupled to the driving side guide rod 100 is driven to linearly move along the driving side guide rod as the door is opened or closed. For this purpose, as shown in FIG. 5, one of the two sewing holes coupled to the upper end of the upper X-arm is fixed, and the other of the rack gear 134 is coupled, and the rack gear is rotated by the motor 136. The pinion 138 to be engaged. Accordingly, when the pinion is rotated by the drive motor, the sewing hole coupled to the rack gear engaged with the pinion is moved along the driving side guide rod, thereby expanding or folding the upper X-arm.

The rack gear may preferably have a structure in which spiral teeth are formed in the frame as shown in the partial detail view of FIG. 6. In the present invention, according to the rotation of the pinion is coupled to the upper end of the upper end of the upper X-arms along the driving side guide rods are separated from each other or close to each other is driven to expand or fold the upper X-arms. Therefore, by controlling the rotation of the pinion, it is possible to drive the upper x-arm to be folded or unfolded. The rotation of the pinion is controlled by a controller that receives a signal transmitted from a sensor that detects that the door is opened or closed, thereby controlling the position of the elevator foot when the door is closed and when the door is opened.

In the present invention, the elevating scaffold is to move up and down and horizontal movement at the same time, the movement path of the elevating scaffold is easily adjustable through the length ratio of the X-arm. That is, as shown in FIG. 7, when the upper X-arm has a length of m and n based on the intersection and the lower X-arm has a length of p and q based on the intersection, the Shanghai moving distance and the horizontal movement are as follows. Calculating the ratio of distances is

이고 삼각형의 닮음의 원리를 고려하면 상부 엑스아암의 교차점을 기준으로 아랫 부분의 엑스아암이 형성하는 이등변 삼각형의 높이는 상기 수식의 (n/m)배이다. 따라서 상부 엑스아암(102)에 의하여 형성되는 구동측 가이드봉과 중간 가이드봉(108) 사이의 거리는

가 된다.As shown in FIG. 7, when the distance between the upper ends of the upper X-arms 102 coupled to the driving side guide rods (not shown) by the sewing holes is s, based on the intersection of the upper X-arms, The upper arm is an isosceles triangle with m on the side and s on the bottom, so the height of this isosceles triangle is

Considering the principle of similarity of the triangle, the height of the isosceles triangle formed by the lower part of the X-arm based on the intersection of the upper X-arms is (n / m) times the above equation. Therefore, the distance between the driving guide rod and the intermediate guide rod 108 formed by the upper X-arm 102 is

Becomes

임을 알 수 있다. Similarly, the distance between the intermediate guide rod 108 and the scaffold guide rod (not shown) formed by the lower X-arm 110 is

It can be seen that.

Therefore, as the sewing hole coupled to the rack gear is moved, when the upper X-arm and the lower X-arm are folded or unfolded, it can be seen that the vertical distance or the horizontal distance that the lifting foot moves is a function of m, n, p, q. Therefore, it is possible to adjust the ratio of the vertical movement distance and the horizontal movement distance of the elevating scaffolding through the values of m, n, p, q so that the resulting movement trajectory can be adjusted. That is, it can be seen that the ratio of the vertical movement distance and the horizontal movement distance of the elevating scaffold can be adjusted through the dimensions of the upper X arm or the lower X arm.

이고 하부 엑스아암에 의하여 형성되는 중간 가이드봉과 발판 가이드봉 사이의 거리 D₂는

이기 때문에

임을 알 수 있다. 따라서 m과 q의 값을 조절하여 이 비율을 조절할 수 있으며 이를 통해 승강발판의 상하이동거리와 수평이동거리의 비를 조절할 수 있음을 알 수 있 다. 예를 들어 상하 이동거리에 비하여 수평이동거리가 2배가 되게 하고 싶으면, m : n : p : q = 1 : 1 : 1 : 3으로 형성하면 된다. For example, if the dimension of the upper X-arm and the lower X-arm is selected to hold a special relationship of n = p, the vertical distance to height difference D ₁ between the driving side guide rod and the middle guide rod is

And the distance D ₂ between the intermediate guide bar and the step guide bar formed by the lower X-arm

Because

It can be seen that. Therefore, this ratio can be adjusted by adjusting the values of m and q, and it can be seen that the ratio between the Shanghai moving distance and the horizontal moving distance of the elevator platform can be adjusted. For example, if the horizontal moving distance is twice as large as the vertical moving distance, m: n: p: q = 1: 1: 1: 3 can be formed.

As described above, in the present invention, simply selecting the dimensions of the upper X-arm and the lower X-arm in consideration of variables such as the structure of the vehicle, it is possible to adjust the ratio of the horizontal moving distance and the Shanghai moving distance of the elevator foot as desired. The movement trajectory of the elevating scaffold can be formed.

In the present invention, the moving path of the elevating scaffold may be adjusted by the number ratio of the X-arms. That is, as shown in FIG. 7, the moving path of the elevating scaffold may be adjusted through the dimensions of the upper x-arm and the lower x-arm, but the moving path may be adjusted through the number of x-arms as shown in FIG. 8. That is, the upper X-arm or the lower X-arm, or both, may be configured by combining a plurality of X-arms in series as shown.

In the simplest case, the upper x-arm consists of one x-arm with m: n = 1: 1, and the lower x-arm has two x-arms with p: q = 1: 1 in series. Assume that the connection is as follows. Then, as the elevator platform moves up and down by one, it moves horizontally by two. That is, it can be seen that the ratio of the vertical moving distance and the horizontal moving distance of the elevating scaffold is 1: 2. In this way, the movement path of the elevating scaffold can be adjusted by the number ratio of the X-arms.

In conclusion, the moving path of the lifting platform can be adjusted only by the size of the X-arm, but can also be adjusted by the number ratio of the X-arms, or the combination of both dimensions and the number of the X-arms can be adjusted to adjust the moving path of the lifting platform.

On the other hand, the elevating scaffold 120 is also the weight of its own, and further heavy loads such as the weight of a person can be carried thereon. Therefore, in the present invention, it is preferable that a mechanical support structure is also formed that can effectively support the load applied to the elevator foot. To this end, the vertical guide support frame 123 is guided by the horizontal guide support frame 126 and the horizontal guide support frame 126 coupled to the vertical movement frame 124 and vertical movement frame guided by it, as shown therein It is preferable that the structure of the horizontal moving frame portion 128 to be moved is formed.

The vertical guide support frame 123 is fixed to the vehicle body frame and is formed long in the vertical direction. At least one cutout 130 is formed at a side of the vertical guide support frame. The cutout is preferably formed long in the longitudinal direction. Meanwhile, a vertical moving frame 124 coupled to the inside of the vertical guide support frame and guided by the vertical guide support frame to be moved up and down is formed as shown. Protruding portion 132 is formed on the side surface of the vertical moving frame corresponding to the cutout 130 is configured to protrude through the cutout. Therefore, when the protrusion is moved to the end of the incision, the protrusion is caught at the end of the incision, further movement is limited.

According to this principle, when the upper X-arm and the lower X-arm are unfolded, and the lifting foot comes to the first position of the lower part of the door of the vehicle, the protrusion 132 of the vertical moving frame 124 is caught at the end of the cutout 130 and is vertical. Further downward movement of the moving frame is limited, and further, the load applied to the vertical moving frame is transmitted to the vertical guide supporting frame by the contact of the protrusion and the incision, so that the heavy load applied to the lifting platform at the moment of stepping on the lifting platform is supported by the vertical guide supporting frame. It will be supported at 123. Since the vertical guide support frame is firmly coupled to the body frame, it can support heavy loads.

On the other hand, as shown in the end of the vertical moving frame 124, the horizontal guide support frame 126 is bent in a right-angled direction in the shape of the L-shape is coupled. The support 125 is bent at the lower end of the vertical moving frame may be formed to effectively support the load of the horizontal guide support frame, as shown in the coupling guide 127 and the horizontal guide support frame 126 Can be combined. The horizontal moving frame portion 128 is coupled to the inner side of the horizontal guide support frame so that the horizontal moving frame portion is guided by the horizontal guide support frame to be movable in the longitudinal direction of the horizontal guide support frame. The horizontal moving frame portion may preferably form two or more channels. That is, when the horizontal moving frame is to be moved a relatively long distance in the horizontal direction, it is necessary to form a plurality of channels. Accordingly, as shown in the drawing, the horizontal moving frame may be configured as a dual structure of the outer channel portion 128-1 and the inner channel portion 128-2 coupled to the inner side thereof, and may be formed in multiple structures as necessary. Of course.

In the present invention, the elevating scaffold is formed to be movable by the driving device so that the scaffold is moved to the lower part of the vehicle body during driving, and the scaffold is moved to the lower end of the door only when the vehicle is moved up and down after stopping the vehicle. It has an effect of preventing the vehicle body from being substantially lowered, such as the footrest touching the ground.

On the other hand, the present invention by moving the elevator platform in the horizontal and vertical direction at the same time by a simple structure called a double X-arm, by allowing the elevator platform to move regularly in the horizontal and vertical direction at the same time only with a simple drive structure through the rack gear and pinion By controlling only the rotation of the pinion without complicated electrical control, it has the effect of achieving regular movement in the horizontal and vertical directions of the elevator foot.

In addition, the present invention allows the movement trajectory of the elevating scaffold by selecting the dimensions of the X-arm, for example, the ratio of the vertical movement distance and the horizontal movement distance of the elevating scaffold can be formed as desired so that the most suitable movement trajectory for each passenger car can be obtained. It has the effect of making it simple to form.
