Therefore, when the platform 130 is moved forward by the first driving unit 160, the ring 191 of the platform 130 is locked to the locking unit 190 mounted to the fixing plate 120. In order to unfold the sliding lift 110 in this state, the unlocking of the locking unit 190 must be performed before the operation of the second driving unit 170. The locking unit 190 has the same structure as the locking unit for opening and closing the trunk door of the vehicle, and a detailed description of the locking unit will be omitted.

12 and 13, guide rails 133 having a C-channel structure are formed on both outer sides of the platform 130 in the longitudinal direction, and rollers are formed on both inner surfaces of the fixing frame 141. 121 is mounted, the roller 121 is rotated by the movement of the guide rail 133 in the state supporting the guide rail 133 is located inside the guide rail 133. And ball bearings 123 are mounted on both inner surfaces of the fixing frame 141 to press and support the side surfaces of the guide rails 133. As described above, the guide rail 133 is supported by the roller 121 and the side surface of the guide rail 133 is pressed and supported by the ball bearing 123 so that the platform 130 is moved forward and backward by the first driving unit 160. It prevents the flow in the horizontal direction and the vertical direction when moving to the.

12 and 14, the first and second stoppers 134 and 135 are respectively fixed to different heights at both ends of the side surface in the longitudinal direction of the platform 130, and the inner surface of the fixing frame 141 is fixed to each other. At different heights, the first and second limit switches 151 and 152 are fixed to correspond to the first and second stoppers 134 and 135. In detail, when the platform 130 moves forward and backward to the inside or the outside of the fixed plate 120 by the first driving unit 160, the first stopper 134 is in contact with the corresponding first limit switch 151. When the second stopper 135 contacts the corresponding second limit switch 152, the platform 130 recognizes that the platform 130 is drawn into or pulled out of the fixed plate 120 and controls the operation of the first driving unit 160. .

As shown in FIG. 15, the platform 130 is hinged to the inlet of the platform 130 such that the slope 131 is easily lifted or lowered to the upper surface of the platform 130. When boarding or getting off, the slope 131 is inclined so that the wheelchair can move up and down, and after boarding, the slope 131 is vertically locked to prevent the wheelchair from moving backward.

The slope 131 is hinged to both sides of the platform 130 is pivoted in the vertical direction, the fixing latch 132 is fixed to both sides of the slope 131. In addition, the platform 130, the locking latch 136 for locking the fixing latch 132 is hinged, the coil spring 137 connects the rotating latch 136 and the platform 130. The coil spring 137 provides an elastic force so that the rotation latch 136 moves downward, and one end of the coil spring 137 is fixed to the lug 138 formed on the platform 130. The lug 138 interferes with the rotary clasp 136 and supports the rotary clasp 136 so that the rotary clasp 136 is positioned at a point where the rotary clasp 136 can be locked with the fixed clasp 132 fixed to the slope 131. Perform convenience functions. And the handle 139 is fixed to the rotary latch 136 upwards. Accordingly, when the slope 131 is turned upward, the fixing latch 132 is locked to the rotating latch 136 and the coil spring 137 provides an elastic force to maintain the locked state. In this state, when the slope 131 is to be opened, when the handle 139 is lifted upward, the rotation latch 136 is also unlocked while turning upward, and the slope 131 pivots downward to open the platform 130. .

Meanwhile, as illustrated in FIG. 16, the third and fourth stoppers 143 and 144 are fixed to the link unit 140 that is folded or unfolded, and the third and fourth stoppers 143 and 144 are fixed to the fixing plate 120. ) Are mounted to third and fourth limit switches 153 and 154 that interfere with each other. The third stopper 143 interferes with the third limit switch 153 corresponding to the link portion 140 when the link portion 140 is erected vertically, and the fourth stopper 144 fixes the link portion 140 through the vertical state. If the fourth limit switch 154 interferes with the plate 120 and the fourth stopper 144 and the fourth limit switch 154 interfere with each other, the platform 130 is seated on the fixed plate 120. .

The second driving unit 170 for operating the link unit 140 is a pneumatic system in which the stroke is stretched, and the link unit 140 is folded or unfolded by the stretching of the stroke of the second driving unit 170. In operating the folded link unit 140 to be folded, the link 140a is operated by the contraction of the stroke of the second driving unit 170 until the link 140a of the link unit 140 is folded vertically, but the link 140a is operated. When the c) exceeds the vertical state, the speed of folding by the weight of the link 140a is accelerated, so that the rotation of the link unit 140 is accelerated so that a smooth operation is not performed and an impact occurs. In order to solve such a problem, when a signal is input from the third limit switch 153 when the link 140a of the link unit 140 is standing vertically, the second driving unit 170 accelerates the link unit 140. The contraction speed of the stroke is slowed to suppress the pressure, and when a signal is input to the fourth limit switch 154, the operation of the second driving unit 170 is stopped. By controlling the operation of the second driving unit 170 in such a manner, it is possible to reduce the impact on the disabled person located on the platform 130. The operation of the link unit 140 described above is a description of a process of folding the link unit 140. On the contrary, even when the link unit 140 is unfolded, the link unit 140 is reversely applied to signals generated by the fourth and third limit switches 154 and 153. By this, the second driving unit 170 is operated.

Meanwhile, in order for the sliding lift 110 to operate, the rear bumper 105 pivots downward with the rear door 103 of the vehicle open so that the sliding lift 110 does not interfere with the platform 130. The third driving unit 180 is hingedly coupled to the vehicle and is connected to the rear bumper 105. The third driving unit 180 is also a pneumatic system in which the stroke is stretched and contracted. As the stroke of the third driving unit 180 is contracted, the rear bumper 105 pivots downward and the rear of the third driving unit 180 is extended as the stroke is extended. The bumper 105 pivots upward and returns to its original position.
