The number of the people with the disabled limbs is 2412 thousands of people, and the proportion of the people with the disabled limbs accounts for 29.07 percent of the total number of the people with the disabled limbs. In addition, data published by the national committee for old age in the country show that the population of the aged 60 years and above reaches 1.85 hundred million people and accounts for 13.7 percent of the total population by the end of 2011. By the end of 2013, the population of the aged people in China is expected to exceed 2 hundred million, by 2025, the population of the aged people is expected to exceed 3 hundred million, and by 2033, the population of the aged people is expected to exceed 4 hundred million. One of the major obstacles of lower limb handicapped and elderly persons is the reduced ability to travel outdoors, and even more likely to be unable to walk.
Travel tools designed for the disabled lower limbs and the elderly, such as wheelchairs, cars for the disabled, ramp type wheelchair hand-propelled lifts, and converted disabled vehicles, have appeared on the market. However, the wheelchair is suitable for short distance and long distance, but the wheelchair still needs the assistance of normal people when the disabled people get on or off the vehicle, and the disabled people can only relieve the difficulty to a certain extent and have a long distance to meet the requirements of the disabled people. In order to solve the problem of automatic getting on and off of the vehicle by the wheelchair, a device for going out and riding the vehicle, which can fully adapt to the self condition of the disabled, must be developed and designed so as to facilitate outdoor going out of the disabled with lower limbs in the wheelchair.

The wheelchair positioning and fastening device 7 can ensure that the electric wheelchair and the movable platform 1 are always in a fixed connection state in the movement process.
The device for getting on and off the train is a three-degree-of-freedom series mechanism. The movement in three directions includes: the slide block 8 moves horizontally in the transverse direction on the frame 9; the suspension frame 2 moves up and down; the movable platform 1 moves longitudinally and horizontally on the suspension bracket 2. Wherein, the power of the transverse horizontal movement of the sliding block 8 on the frame 9 is provided by a right motor 36, the up-and-down movement of the suspension bracket 2 is provided by an electric push rod 10, and the power of the longitudinal movement of the movable platform 1 on the suspension bracket 2 is provided by a left motor 61. The mechanism is characterized in that the mechanism can finally realize the stable motion of the movable platform 1 in the transverse direction, the longitudinal direction and the up-down direction, and the mechanism is electrically driven and has no pollution to the external environment.
The structure of another embodiment of the device is as follows: the slide guide branch 3 is replaced by a right electric push rod 12 (see fig. 6) mounted between the slide 8 and the frame 9.
The working principle and the operation process of the getting-on and getting-off device are as follows: assuming that the initial position is such that the special vehicle and the electric wheelchair are both parked on the road surface, the getting-on/off device is inside the special vehicle (see fig. 7 c). A person with lower limb disability moves the electric wheelchair to the side door position of a special vehicle, operates a remote controller, opens a vehicle door, starts a right motor 36, drives a transverse lead screw 34 to rotate, converts the rotation of the transverse lead screw 34 into the leftward horizontal movement of a slide block 8 along a transverse guide rail 39 through a slide block guide branched chain 3, stops moving when the slide block 8 moves to the position of a left side support seat 31 (see figure 7 b), then drives the suspension frame 2 to move downwards through a first middle branched chain 4, a second middle branched chain 5 and an electric push rod 10, and stops moving when the suspension frame 2 moves to the position that the lower surface of the suspension frame contacts with the ground (see figure 7 a), and the device finishes getting-off movement; a person with lower limb disability sits on the electric wheelchair, grasps the handrail 71, aligns the tire of the electric wheelchair with the wheelchair guide groove 73 on the movable platform 1 through the slope 66, and enables the electric wheelchair to realize directional movement on the movable platform 1; when the foremost end of the electric wheelchair is contacted with the positioning baffle plate 72, the electric wheelchair stops moving, and at the moment, a front side positioning pin 75 on the front side boss 74 and a rear side positioning pin 77 on the rear side boss 78 enter a positioning hole on the corresponding electric wheelchair, and the control handle 76 is clamped when being pulled backwards to the lowest position, so that the electric wheelchair is fixed with the movable platform 1; the suspension frame 2 moves upwards through the first middle branch chain 4, the second middle branch chain 5 and the electric push rod 10, and the suspension frame 2 stops moving upwards when the lower surface of the suspension frame is at the same level with the upper surface of the frame 9 (see fig. 7 b). Then, a right motor 36 is started, the rotation of the transverse lead screw 34 is converted into the rightward horizontal movement of the slide block 8 along a transverse guide track 39 through the slide block guide branched chain 3, the suspension frame 2 stops moving when moving to the position of the cab (see fig. 7 c), and the mechanism realizes the boarding movement; the vehicle door is closed, then the left motor 61 is started, and the rotation of the longitudinal screw 63 is converted into the longitudinal horizontal movement of the movable platform 1 along the longitudinal guide track 65 through the movable platform guide branched chain 6, so that the front and back position adjustment of the driver seat (namely the electric wheelchair) is realized. After the adjustment is finished, the person with lower limb disability can drive the automobile by himself to go out for a long distance outdoors. When the destination is reached, the lower limb handicapped person can repeat the process, so that the lower limb handicapped person can finish getting off the vehicle and the mechanism is reset. When the electric wheelchair is separated from the special vehicle, the person with lower limb disability can freely move in a short distance.
The wheelchair getting-on and getting-off device is arranged at the positions of the driver seat and the co-driver seat, a lower limb handicapped person sits on the electric wheelchair, and can finish the up-and-down movement of the suspension rack, the transverse horizontal movement of the suspension rack and the longitudinal horizontal movement of the movable platform by operating the remote controller, so that the electric wheelchair can conveniently enter the special vehicle from the side door and adjust the front-and-back position of the electric wheelchair, and the lower limb handicapped person can get on or off the special vehicle independently.
It should be noted that the installation terms of the components such as "upper, lower", "front, rear", "left, right" and the like in the device of the present invention are relative to each other as shown in the drawings, or are only for convenience of description, and do not represent the uniqueness and the necessity of the installation position. The embodiments of the device according to the invention can be adapted and varied substantially as required.
