The user first presses the button on the armrest of the wheelchair frame 1 to make the No. 1 driving device 12 work, and the No. 1 rotating shaft 14 is fixedly installed at the output end of the No. 1 driving device 12 to make the No. 1 rotating shaft 14 rotate, and at the same time, the No. 1 rotating shaft 14 is fixedly installed at the output end of the No. 1 driving device 12. At least two No. 1 gears 13 are fixedly mounted on 14, so that the No. 1 gear 13 is driven to rotate, and the No. 1 gear 13 is meshed and connected with the gear plate 11, and the gear plate 11 is fixedly connected with the lower surface of the support plate 10, so that when the No. 1 gear 13 rotates, the gear plate 11 is driven to move horizontally, and a hole is opened on one side of the shell 9, so that the support plate 10 slides into the shell 9, and when the support plate 10 is extended to a sufficient length, the No. 1 driving device 12 is closed, so that the caregiver can place the patient's legs on the support plate 10, and at the same time, the caregiver pulls out the fixing strap 17 and connects it to the fixed structure, so that the fixing strap 17 can fix the patient's upper body, thereby avoiding the possibility of unconscious patients sliding down involuntarily on the wheelchair and causing injury.

[0026] like Figure 1-Figure 2 As shown, the first gear 13 is rotatably connected to the housing 9, and at least two electric telescopic rods 21 are fixedly installed on the lower surface of the support plate 10. The support plate 10 is used to place the patient's legs. By setting the electric telescopic rod 21, the caregiver can turn on the switch of the electric telescopic rod 21 when the wheelchair is not moved, so that the electric telescopic rod 21 is extended and the lower surface is in contact with the ground, so that the wheelchair can be placed firmly. At this time, it is more convenient to take care of the patient in the wheelchair. When the electric telescopic rod 21 is not needed when moving the wheelchair, the caregiver only needs to press the switch to retract the electric telescopic rod 21.

[0027] Example 2

[0028] A multifunctional wheelchair for elderly care protection, such as Figure 1-Figure 3As shown, a seat cushion 2 is fixedly installed on the top of the shell 9, and at least two No. 2 driving devices 4 are fixedly installed inside the seat cushion 2. The output ends of the two No. 2 driving devices 4 are fixedly installed with No. 2 rotating shafts 5, and the two No. 2 rotating shafts 5 extend to the outside of the seat cushion 2. A No. 2 gear 6 is fixedly installed on the two No. 2 rotating shafts 5, and the No. 2 gear 6 is meshed and connected with a No. 3 gear 7. A No. 3 rotating shaft 8 is fixedly installed between the two No. 3 gears 7, and the No. 3 rotating shaft 8 is fixedly connected to the seat back 3. When the user needs to adjust the angle of the seat back 3 of the wheelchair, the switch of the No. 2 driving device 4 is turned on, so that the No. 2 driving device 4 works. By setting the output of the No. 2 driving device 4 A No. 2 rotating shaft 5 is fixedly installed at the output end, so that the No. 2 rotating shaft 5 can rotate. A No. 2 gear 6 is fixedly installed on the No. 2 rotating shaft 5, and the No. 2 gear 6 is meshingly linked with the No. 3 gear 7. When the No. 2 rotating shaft 5 rotates, the No. 2 gear 6 and the No. 3 gear 7 are driven to rotate. At the same time, a No. 3 rotating shaft 8 is fixedly installed between the two No. 3 gears 7, and the chair back 3 is fixedly installed on the No. 3 rotating shaft 8. When the No. 3 gear 7 rotates, the No. 3 rotating shaft 8 is driven to rotate, thereby driving the chair back 3 to rotate, so that the chair back 3 can be adjusted in angle, making the patient more comfortable in the wheelchair.

[0029] like Figure 1-Figure 4 As shown, a protective shell 15 is fixedly installed at one end of the chair back 3, and a rotating rod 16 is rotatably installed inside the protective shell 15. The rotating rod 16 extends to the outside of the protective shell 15, and the rotating rod 16 is fixedly connected to one end of the fixing strap 17. A mounting box 19 is fixedly installed at one end of the chair back 3 away from the protective shell 15, and at least two fixing groove buckles 18 are fixedly installed at one end of the fixing strap 17 away from the rotating rod 16. At least two fixing buckles 20 are fixedly installed on the inner side of the mounting box 19. The user manually rotates the rotating rod 16 to rotate the fixing strap 17 out of the protective shell 15, pulls the fixing strap 17 to the mounting box 19, aligns the fixing groove buckle 18 on the fixing strap 17 with the fixing buckle 20 inside the mounting box 19, and presses it down. The fixing strap 17 is made of soft material, so that when the fixing groove buckle 18 is firmly connected with the fixing buckle 20, the fixing strap 17 can fix the patient's upper body.

[0030] Working principle: The user first presses the button on the armrest of the wheelchair frame 1 to make the No. 1 driving device 12 work, and the No. 1 rotating shaft 14 is fixedly installed on the output end of the No. 1 driving device 12, so that the No. 1 rotating shaft 14 rotates, and at least two No. 1 gears 13 are fixedly installed on the No. 1 rotating shaft 14, so that the No. 1 gear 13 is driven to rotate, and the No. 1 gear 13 is meshed and connected with the gear plate 11, and the gear plate 11 is fixedly connected with the lower surface of the support plate 10, so that when the No. 1 gear 13 rotates, the No. 1 gear 13 rotates. When rotating, the gear plate 11 is driven to move horizontally, and a hole is opened on one side surface of the shell 9, so that the support plate 10 can slide into the shell 9. When the support plate 10 is extended to a sufficient length, the No. 1 driving device 12 is closed, so that the caregiver can place the patient's legs on the support plate 10. At the same time, the caregiver pulls out the fixing strap 17 and connects it to the set fixing structure, so that the fixing strap 17 can fix the patient's upper body, thereby avoiding the possibility of an unconscious patient sliding down involuntarily on the wheelchair and causing injury.
