Principle of embodiment:

in normal times, a patient directly uses two hands to drive the roller 1 to rotate; when the illness condition of a patient is aggravated, the roller wheel is not rotated by strength, at this time, the wheelchair is provided with a switch, the switch is pressed, the reel motor rotates, the reel 17 rotates, the pull wire 16 pulls the lifting rod 14, the lifting rod 14 moves downwards, the first connecting rod 11, the second connecting rod 12 and the electric telescopic component 10 can be regarded as a triangle, the triangle deforms along with the shortening of the electric telescopic component 10, and the distance from the lower end of the second connecting rod 12 to the bottom plate 7 is larger than the distance from the upper end of the second connecting rod 12 to the seat plate 2; therefore, according to the theory of similar triangle, when the upper end of the electric telescopic assembly 10 descends, the upper end of the first connecting rod 11 also descends at the same time, and the descending distance of the upper end of the electric telescopic assembly 10 is greater than the descending distance of the upper end of the first connecting rod 11, and the upper end of the first connecting rod 11 descends when descending, the upper end of the first connecting rod 11 can slide towards the direction away from the chair back 3 at the lower side of the seat plate 2, under the initial state, the seat plate 2 is horizontal, because after the electric telescopic assembly 10 shortens, the descending distance near the chair back 3 is more, and the seat plate 2 can be seen as counterclockwise rotation, and at the same time, the electric telescopic assembly 10 is vertical, therefore, the seat plate 2 moves towards the side away from the chair back 3 slightly compared with before shortening after the electric telescopic assembly 10 shortens, and this is favorable for the adjustment of the angle of the chair back 3. Meanwhile, as the seat plate 2 descends near one end of the chair back 3, the end of the seat plate 2 descends along the chair back 3 (in this embodiment, a coil spring is arranged between the lower plate 20 of the chair back and the bracket 8, so that pressure always exists between the lower plate 20 of the chair back and the seat plate 2), the end of the seat plate 2 moves from top to bottom in the groove 22, the upper end of the chair back 3 rotates towards the rear side under the action of the guide slope 9 (the advancing direction of the wheelchair is defined as the front side, and the opposite side is the rear side), when the end of the seat plate 2 reaches the lower end of the groove 22, the seat plate 2 pushes the control rod 21, the control rod 21 moves downwards, the hook pulling wire 27 pulls the hook 25, the hook is separated from the slide block 24, the slide block 24 moves upwards under the action of the second spring, at this time, the push rod 28 moves upwards, the push rod 28 rotates the handle 19 and the upper plate 18 of the chair back (initially, the chair back 3 is adapted to the patient, the top of the head of the patient is positioned at the upper plate 18 of the chair back, when the electric telescopic assembly 10 is shortened, the height of the top of the head of the patient is reduced due to the fact that the seat plate 2 is lowered, and at this time, the height of the top of the head of the patient is lower than the height of the lower end of the lower plate 20 of the chair back), after the upper plate 18 of the chair back is rotated, the oxygen mask 34 is located on the front side of the head of the patient, at this time, the patient can be easily taken down by hand, and the air pipe 33 is spiral and is similar to the shape of a telephone line, so that the air pipe 33 can be conveniently stored, and the oxygen mask 34 can be conveniently taken by the design of the magnet 36; at this time, the push rod 28 plays a role of supporting the handle 19, and at this time, because the angles of the chair back 3 and the chair plate 2 are adjusted, at this time, the patient lies more "flat" before comparing the angle adjustment (the angle adjustment range is smaller in fig. 4, technicians can easily realize larger angle adjustment by adjusting the guide slope 9, the first connecting rod 11, the second connecting rod 12 and the like, and do not unfold here), which is more beneficial to saving physical strength and oxygen inhalation; the patient is then inconveniently rotated by the rollers, and the handle 19 facilitates the caregiver to push the cart.

It should be noted that the present electric telescopic assembly 10 has a shock absorbing effect at ordinary times.

After use, the reel 17 rotates in the reverse direction, at this time, the sleeve spring 15 extends, the electric telescopic assembly 10 extends, the seat plate 2 and the seat back 3 return to the initial positions, when the seat plate 2 is reset, the seat plate 2 pulls the reset wire 29, at this time, the second spring is shortened, the slider 24 moves downward, and when the seat plate 2 is reset, the slider 24 is hooked with the slider 24 again. The push rod 28 moves downwards, the handle 19 and the upper chair back plate 18 rotate, the lower end of the upper chair back plate 18 is abutted against the limiting block 38 again, and the upper chair back plate 18 is flush with the lower chair back plate 20.
