[0002] Disabled people refer to those with long-term deficiencies in limbs, language, hearing, mental, intellectual or multiple aspects. These deficiencies interact with various obstacles, which may prevent disabled people from fully and effectively participating in society on an equal basis with able-bodied people. A wheelchair is a chair equipped with wheels to help replace walking, and is divided into electric and manual folding wheelchairs. It is an important mobile tool for the wounded, sick and disabled for home rehabilitation, turnover transportation, medical treatment and outdoor activities. A wheelchair not only meets the transportation needs of limb-disabled and mobility-impaired people, but more importantly, it facilitates the movement and care of patients by their families, enabling patients to exercise their bodies and participate in social activities with the help of a wheelchair. An ordinary wheelchair generally consists of a foldable frame, front and rear wheels, left and right knee guards and footrests, left and right detachable armrests, a handbrake device, a seat, a backrest with a medical imaging data bag, a bedpan, a urine collection bag hook and an electric standing part, etc.

The top of the inner wall of the external housing frame 1 is fixedly connected to the back of the control system 3. The top of the mounting seat plate 2 is fixedly connected to the bottom of the external housing frame 1. On both sides of the top of the front of the external housing frame 1, tongue locks 18 are fixedly connected. A hand grip 19 is fixedly connected to the top of the front of the external housing frame 1. Through the settings of the tongue lock 18 and the hand grip 19, when the lifting mechanism 6 is in the initial state, the lifting mechanism 6 is locked. A vertical plate 5 is fixedly connected to the bottom of the mounting seat plate 2, and a lifting mechanism 6 is arranged on the back of the vertical plate 5. The lifting mechanism 6 includes a first support beam 61. A stopper 7 is fixedly connected to the right side of the front of the first support beam 61. A first limit block 8 is fixedly connected to the bottom of the second support beam 66. A controllable compression gas spring 9 is fixedly connected to the left side of the lifting beam 65. When the controllable compression gas spring 9 expands, it applies pressure to the tabletop. When the tabletop retracts, it can be recovered by the self-return force of the compression gas spring. And the end of the controllable compression gas spring 9 away from the lifting beam 65 is fixedly connected to a first hinge plate 10. The inner wall of the first hinge plate 10 is fixedly connected to the surface of the main shaft 67 through a through hole. Second hinge plates 11 are threadedly connected to the front and back of the lifting platform 68 by bolts. The left side of the first support beam 61 is rotatably connected to the top of the back of the vertical plate 5. A buffer compression air spring 62 is fixedly connected to the top of the mounting seat plate 2, and the top of the buffer compression air spring 62 is fixedly connected to the top of the left side of the first support beam 61 through a connecting member. A triangular support pair 63 is threadedly connected to the left side of the back of the vertical plate 5. The right side of the triangular support pair 63 is rotatably connected to a telescopic hydraulic cylinder 64. The telescopic hydraulic cylinder 64 is controlled by the control system 3, and the hydraulic power unit 4 provides hydraulic oil for it. The right side of the first support beam 61 is rotatably connected to a lifting beam 65 through a connecting member. The lifting beam 65 is covered with an outer protective plate. A second limit block 16 is threadedly connected to the bottom of the left side of the lifting beam 65. An adjusting bolt 17 is threadedly connected to the left side of the vertical plate 5. The adjusting bolt 17 can adjust the position to slightly adjust the descending height and retracting angle of the lifting platform 68, and is applicable to tabletops of different heights within a certain range. One end of the output shaft of the telescopic hydraulic cylinder 64 is rotatably connected to the right side of the bottom of the first support beam 61 through a connecting block. The bottom of the right side of the back of the vertical plate 5 is rotatably connected to a second support beam 66, and the right side of the second support beam 66 is rotatably connected to the left side of the lifting beam 65 through a connecting block. The side of the lifting beam 65 away from the first support beam 61 is rotatably connected to a lifting platform 68 through a main shaft 67. A front guard plate 12 is rotatably connected to the left side of the lifting platform 68. A rear guard plate 13 is rotatably connected to the right side of the lifting platform 68.

Protective handrails 15 are fixedly connected to both the front and back on the left side of the lifting platform 68. Parts not involved in this device are the same as or can be implemented using the prior art.

[0032] During operation, manually flip the lifting platform 68 by 90 degrees. Limit and fix the angle of the lifting platform 68 through the stopper 7, the first limit block 8, and the second limit block 16. The buffer compression air spring 62 is stressed. Then start the telescopic hydraulic cylinder 64 to drive the lifting beam 65 to move downward. While the lifting beam 65 is moving, the first support beam 61 and the second support beam 66 rotate between the vertical plate 5 and the lifting beam 65 to play a supporting role. During the downward flipping process of the lifting platform 68, it rotates between the main shaft 67 and the first hinge plate 10 and the lifting beam 65. The second hinge plate 11 is connected to the lifting platform 68 by bolts. The controllable compression gas spring 9 applies pressure to the lifting platform 68. When retracting the lifting platform 68, flip the lifting platform 68 upward and recover it by the self-returning force of the controllable compression gas spring 9. Set an adjusting bolt 17 on the side of the vertical plate 5. By adjusting the position of this adjusting bolt 17, slightly adjust the lowering height and retracting angle of the lifting platform 68, which is applicable to table surfaces of different heights within a certain range. After the lifting platform 68 descends to the ground, use the reduction motor installed on the side to automatically flip and open the front guard plate 12 and the rear guard plate 13. The wheelchair gets onto the lifting platform 68. Then, use the reduction motor installed on the side again to flip the front guard plate 12 and the rear guard plate 13 upward by 90 degrees to protect the wheelchair. After the wheelchair enters the lifting platform 68, start the telescopic hydraulic cylinder 64 again, and raise the lifting platform 68 to the height of the vehicle body floor through reverse operation. Lower the rear guard plate 13 again, and the disabled person can get into the vehicle. During the ascending process, the disabled person sitting in the wheelchair can hold the protective handrail 15, making it safer to use.
