Abstract

The invention discloses a device for enabling a wheelchair to get on or off a vehicle. The device is characterized by mainly comprising a movable platform, a suspension platform, a sliding block guiding branch chain, a first intermediate branch chain, a second intermediate branch chain, a wheelchair positioning fastening device, a sliding block, a machine frame and an electric push rod. The structural layout of the whole device is that the sliding block is connected with the machine frame through the sliding block guiding branch chain, the suspension platform and the sliding block are in symmetric connection through the first intermediate branch chain and the second intermediate branch chain, the movable platform is connected with the suspension platform through a movable platform guiding branch chain, the wheelchair positioning fastening device is installed on the movable platform and used for being connected with an electric wheelchair, and the electric push rod is connected between the suspension platform and the sliding block. The first intermediate branch chain and the second intermediate branch chain are identical in structure and form double parallelogram mechanisms. Under the conditions of guaranteeing that the sliding block is horizontal, movement of the suspension platform is in a translation process and is always kept in a horizontal state, simultaneously two parallelograms are matched to be used, and horizontal movement stability of the movable platform is also guaranteed.
