when the wheelchair moves along the inclined slope surface, the first displacement sensor 802 can detect that the wheelchair is in a displacement state, the inclination angle detector 801 can detect an included angle between the wheelchair and a horizontal plane, the wheelchair is judged to be in an uphill or downhill state, if a patient on the wheelchair is parked on the inclined slope surface for rest at the moment and the wheelchair slides down the slope, the first displacement sensor 802 and the inclination angle detector 801 are matched with each other, the wheelchair can be detected to be in a slope movement state, the loudspeaker 803 and the electric telescopic rod 804 are started at the moment, the loudspeaker 803 gives a prompt, the patient who has a rest and a nearby caregiver are alerted, the electric telescopic rod 804 moves down and then drives the friction block 805 to move down to be in frictional contact with the ground so as to reduce the displacement speed of the wheelchair, and the possibility that the patient on the wheelchair is impacted and injured is reduced.

The wheelchair comprises the following steps:

s1, before a chronic geriatric patient uses the wheelchair, the seat plate 402 and the movable embedding plate 405 are adjusted downwards to be in a flat embedding state, then the patient sits on the surface of the movable embedding plate 405, the two feet are placed on the surface of the extracted pedal plate 301, and immediately a caregiver can hold the handle 101 or the patient drives the air wheel 203 to move by the aid of the hand-push ring 201, so that the wheelchair is pushed to move;

s2, before the patient rotates the hand push ring 201 to move the wheelchair, the restraint belt 1004 on the surface of the round rod 1001 can be drawn out and then stretches across the surface of the seat plate 402 to extend to the surface of the anti-falling rolling plate 5 on the surface of the other group of baffles 103, then the magic veneers 503 at the tail ends of the restraint belt 1004 are adhered to the surface of the sticky wool plate 502 to form a restraint anti-falling effect, in the moving process of the wheelchair, if the wheelchair threatens to roll over, the inclination displacement sensor 505 can detect that the wheelchair has horizontal inclination displacement, then the servo motor 504 is started to drive the rolling rod 501 to rotate, the restraint belt 1004 in a loose state in adhesive connection can be driven to tighten, the patient is tightly restrained on the surface of the wheelchair, so that the possibility that the patient is separated from the wheelchair when the wheelchair is rolled over is reduced, and the side-turning protection is provided for the patient by means of the shell provided by the wheelchair;

s3, when the wheelchair moves along an inclined slope surface, the first displacement sensor 802 can detect that the wheelchair is in a displacement state, the inclination angle detector 801 can detect an included angle between the wheelchair and a horizontal plane, the wheelchair is judged to be in an uphill or downhill state, if a patient on the wheelchair is parked on the inclined slope surface for rest at the moment, the first displacement sensor 802 and the inclination angle detector 801 are matched with each other, the wheelchair can be detected to be in a downhill movement state, the loudspeaker 803 and the electric telescopic rod 804 are started at the moment, the loudspeaker 803 gives a prompt, the resting patient and a nearby caregiver are alerted, the electric telescopic rod 804 moves downwards, the friction block 805 is driven to move downwards to be in frictional contact with the ground to reduce the displacement speed of the wheelchair, and the possibility that the patient on the wheelchair is subjected to impact injury is reduced;

s4, when a caregiver pushes a patient who is inconvenient to move and needs to be reversed, the electric push rod can be started first to contact the ground, the electric lifting rod 403 is started immediately, the movable embedded plate 405 is driven to move upwards, the patient and the movable embedded plate 405 are separated from the wheelchair at the moment, the wheelchair is rotated first and then the movable embedded plate 405 is rotated, and therefore the rotation reversing operation which is easy and labor-saving can be achieved;

s5, when a patient sits on the surface of the wheelchair to go out, in order to ensure the heart rate of the patient to be stable, the wrist part can be attached to the surface of the heart rate sensor 904 at regular time, the detection result of the heart rate sensor 904 is displayed through the display screen 901 so as to grasp the heart rate data of the patient at regular time, and when the heart rate is abnormal, the accommodating groove 902 can be opened to swallow the medicines stored in the accommodating groove in a classified mode so as to relieve the body discomfort caused by the abnormal heart rate.

The working principle is as follows: before a patient rotates the hand push ring 201 to move the wheelchair, the restraint belt 1004 on the surface of the round rod 1001 can be pulled out, then the restraint belt stretches across the surface of the seat plate 402 and extends to the surface of the anti-falling rolling plate 5 on the surface of the other group of baffles 103, then the magic veneers 503 at the tail ends of the restraint belts 1004 are adhered to the surface of the sticky wool plate 502 to form a restraint anti-falling effect, in the moving process of the wheelchair, if the wheelchair threatens to roll over, the inclination displacement sensor 505 can detect that the wheelchair has horizontal inclination displacement, then the servo motor 504 is started to drive the rolling rods 501 to rotate, the restraint belts 1004 in a loose state in an adhesion connection can be driven to tighten, and the patient is tightly restrained on the surface of the wheelchair, so that the possibility that the patient is separated from the wheelchair when the wheelchair rolls over is reduced, and the side-turning protection is provided for the patient by means of the shell provided by the wheelchair;

if a patient on the wheelchair is parked on an inclined slope for rest and the wheelchair slides down, the first displacement sensor 802 and the inclination angle detector 801 are matched with each other to detect that the wheelchair is in a sliding motion state, at the moment, the loudspeaker 803 and the electric telescopic rod 804 are started, the loudspeaker 803 gives a prompt to warn the resting patient and a nearby caregiver, the electric telescopic rod 804 moves downwards to drive the friction block 805 to move downwards to be in frictional contact with the ground so as to reduce the displacement speed of the wheelchair and reduce the possibility that the patient on the wheelchair is impacted and injured;

when a caregiver pushes a patient with mobility disability to move and needs to perform reversing treatment, the electric push rod can be started first to contact the ground, the electric lifting rod 403 is started immediately, the movable embedded plate 405 is driven to move upwards, the patient and the movable embedded plate 405 are separated from the wheelchair, the wheelchair is rotated first and then the movable embedded plate 405 is rotated, and accordingly the rotation reversing operation which is easy and labor-saving can be achieved;

when a patient sits on the surface of the wheelchair to go out, in order to ensure the heart rate of the patient to be stable, the wrist part can be attached to the surface of the heart rate sensor 904 at regular time, the detection result of the heart rate sensor 904 is displayed through the display screen 901, so that the heart rate data of the patient can be mastered at regular time, and when the heart rate is abnormal, the accommodating groove 902 can be opened, and medicines stored in the accommodating groove can be swallowed in a classified mode, so that the body discomfort caused by the abnormal heart rate can be relieved.
