When the experimental operation is carried out on site, the assisted standing work of the wheelchair can be controlled by the control box 201 at the right armrest 105. First, when the button of the control box 201 is pressed, the wheel 110 of the wheelchair is immediately locked by the brake 104, and the anti-rollover device 111 is turned on to ensure the safety of the wheelchair during assisted standing work; then the electric push rod I306 is compressed, the electric push rod II 307 and the electric push rod III 308 are stretched, and the backrest 109 and the seat cushion 106 are slowly raised to realize the safety of the user. Assist standing. At this time, the foldable seat cushion 302 in the seat cushion 106 moves backward and downward with the fixed bracket VII315 as the axis, and the sanitary bedpan 322 slides between the slideway I321 and the slideway II 322, from sliding directly under the seat cushion 106 to the slide It is located at the rearmost wheel 110 in order to bring the folding space for the foldable seat cushion 302. During the movement of the backrest 109 and the seat cushion 106, the angle between the backrest 109 and the vertical direction and the angle between the seat cushion 106 and the horizontal direction are always kept equal, In order to ensure the stability when assisting standing; when the backrest 109 and the seat cushion 106 move to a state of 90 degrees with the ground, they are completely on the same vertical plane, the foldable seat cushion 302 has been folded backwards to the backrest 109 and the seat cushion 106. On the same vertical plane, the sanitary bedpan 322 retreats to the rearmost wheel 110 of the slideway; then the electric push rod I306 is stretched, the electric push rod II 307 and the electric push rod III 308 are compressed, and the backrest 109 and the seat cushion 106 are slowly lowered to achieve alignment When the user is in the standing state, the foldable seat cushion 302 in the seat cushion 106 maintains the previous motion state unchanged, and is in a vertical direction of 90 degrees with the ground. Sliding between the wheels 110 at the rear of the wheelchair to just below the seat cushion 106; finally, when the movement of the backrest 109 and the seat cushion 106 returns to the original state of the wheelchair, the foldable seat cushion 302 inside the seat cushion 106 has been lost, and the seat cushion 106 is just below the seat cushion 106. Sanitary bedpan 322. If the user finishes using the toilet, the wheelchair will perform the same steps as the upside-down movement. First, when the button of the control box 201 is pressed, the wheel 110 of the wheelchair is immediately locked by the brake 104, and the anti-overturning device 111 is turned on to ensure the safety of the wheelchair during the assisted standing work; then the electric push rod I306 is compressed, and the electric push The rod II 307 and the electric push rod III 308 are stretched, and the backrest 109 and the seat cushion 106 are slowly raised to assist the user to stand up. At this time, the foldable seat cushion 302 in the seat cushion 106 moves backward and upward with the fixed bracket VII 315 as the axis. The sanitary bedpan 322 slides between the slideway I320 and the slideway II321, and then slides directly under the seat cushion 106 and retreats to the wheel 110 behind the wheelchair, so as to bring the folding space for the foldable seat cushion 302, and moves between the backrest 109 and the seat cushion 106 In the process, the angle between the backrest 109 and the vertical direction and the angle between the seat cushion 106 and the horizontal direction are always kept equal to ensure the stability of the auxiliary standing; In the vertical plane, the foldable seat cushion 302 has been folded forward to a vertical plane with the backrest 109 and the seat cushion 106 and a horizontal plane with the ground, and the sanitary bedpan 322 retreats to the rearmost wheel 110 of the slide; When stretched, the electric push rod II 307 and the electric push rod III 308 are compressed, and the backrest 109 and the seat cushion 106 are slowly lowered to realize the assisted sitting of the user in the standing state. The movement state remains unchanged, and it is horizontal to the ground. The toilet 322 slides between the slideway I320 and the slideway II321, from sliding at the wheel 110 at the rear of the wheelchair to just below the seat cushion 106; finally, when the backrest 109 and the seat cushion 106 move back to When the wheelchair is in its original state, the foldable seat cushion 302 inside the seat cushion 106 has also returned to its original state, and the wheelchair can continue to be used normally.
