Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical auxiliary instruments, and particularly to a medical nursing wheelchair. Background Art
[0002] As an indispensable and important tool in the modern rehabilitation medical system, the significance of the wheelchair far exceeds the simple scope of getting around. It is not only a powerful assistant for the physically disabled, the mobility-impaired, and the elderly in their daily travel, but also a bridge for them to regain their autonomy in life and actively participate in social activities. With the assistance of the wheelchair, these groups can overcome physical limitations, not only carry out necessary physical exercises to strengthen their physique, but also reintegrate into society, enjoy the pleasure of interacting with people, and participate in various social activities, thus greatly improving their quality of life and mental health.
[0003] In the field of medical care, the application of wheelchairs is even more extensive and in-depth. From the corridors of hospitals to rehabilitation centers, from home care to outdoor convalescence, wheelchairs play a crucial role. It helps patients move conveniently between different treatment areas, ensuring the continuity and efficiency of the treatment process.
[0004] With the rapid progress of technology and the increasing practical needs, the design of electric wheelchairs has become more and more user-friendly and intelligent.

[0024] 2. The present invention is provided with an upper limb training component. The patient holds the handlebars with both hands and pushes forward. The handlebars drive the slider to slide forward in the guide groove, stretching the spring. Then, the patient relaxes the pushing force on the handlebars. Under the action of the spring, the slider and the handlebars are driven to reset automatically. By repeating this operation, the patient can exercise the upper limbs. At the same time, the handlebars are convenient for disassembly and installation, avoiding interference caused by the handlebars when the patient normally uses the wheelchair. The patient can also adjust the distance between the two handlebars according to their own habits, improving the practicability.
[0025] 3. The present invention senses the inclination of the wheelchair through an inclination sensor. By activating the electric push rod III on the lower side with a lower height, under the push of the electric push rod, the top rod and the bottom rod move away from each other, raising the height of the lower side of the wheelchair seat plate, enabling the patient to maintain balance, preventing tipping over, and improving the safety of the patient when using the wheelchair to go up and down slopes.
[0026] Therefore, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

The electric push rods 14 are rotatably connected to the bracket 13, the backrest 11, and the side plates 12 respectively. During use, the backrest 11 or the side plates 12 are controlled to rotate around the connection with the seat plate 10 by the telescopic movement of the electric push rods 14, so as to realize the adjustment of the rotation angles of the backrest 11 and the side plates 12, and further realize the conversion between the bed and the wheelchair. Armrests 15 are provided at both ends of the seat plate 10. The armrests 15 are used to prevent the user from tipping over and play a role in safety protection.
[0053] The two docking components 2 respectively include two mounting plates 20 connected to both ends of the bracket 13. An electric push rod two 25 is connected between the outer side wall of each mounting plate 20 and the outer side wall of the bracket 13. Both ends of the electric push rod two 25 are rotatably connected to the mounting plate 20 and the bracket 13 respectively. By controlling the telescopic movement of the electric push rod two 25, the mounting plate 20 is rotated around the connection with the bracket 13, and the mounting plate 20 is rotated from the vertical state to the horizontal state. On both sides of the lower end of each mounting plate 20, there are sliding grooves 21. Inside each sliding groove 21, there is a vertical bidirectional screw rod 22. At both ends of each sliding groove 21, there are clamping plates 23. Each clamping plate 23 can slide along the long side of the corresponding sliding groove 21 inside the sliding groove 21. Each bidirectional screw rod 22 passes through the two clamping plates 23 and is threadedly connected to the two clamping plates 23. In the middle of each mounting plate 20, there is a driving member one 24, and the driving member one 24 is used to control the synchronous rotation of the two bidirectional screw rods 22. When in use, the side of the wheelchair is attached to the side of the hospital bed, the electric push rod two 25 is started, and the electric push rod two 25 drives the mounting plate 20 to rotate, so that the mounting plate 20 is rotated from the vertical state to the horizontal state, and the two ends of the mounting plate 20 are attached to the bottom surface of the hospital bed. Then the driving member one 24 is started, and the driving member one 24 controls the two bidirectional screw rods 22 to rotate. The bidirectional screw rods 22 drive the two clamping plates 23 to slide towards the middle of the sliding groove 21 to clamp the bed frame, thereby fixing the wheelchair and the hospital bed together. A pressure sensor is provided inside each clamping plate 23. After clamping the bed edge and reaching the specified clamping force, the motor one is automatically turned off.
[0054] The upper limb training component 3 is arranged above the seat plate 10 and is used for the rehabilitation training of the patient's upper body.
[0055] The anti-tipping component 4 is arranged at the bottom of the bracket 13 and is used to adjust the front and rear heights of the wheelchair.
[0056] In one embodiment, please refer to Figures 3 - 4 ., the driving member one 24 includes a motor one. The rotating shafts of the motor one are respectively connected to one ends of two synchronous belts, and the other ends of the two synchronous belts are respectively connected to a bidirectional screw rod 22. The synchronous belts are arranged inside the mounting plate 20 to prevent external dust from affecting the operation of the synchronous belts. By starting the motor one, the motor one drives the two synchronous belts to rotate, and then the two synchronous belts drive the two bidirectional screw rods 22 to rotate synchronously to achieve the driving effect.
[0057] In one embodiment, please refer to Figure 5, four motors 16 are provided at the four corners of the lower end of the seat board 10, and struts 17 are connected between the two sides of the lower end of each armrest 15 and the motor 16. The motor 16 controls the rotation of the strut 17, and the strut 17 drives the armrest 15 to tilt up and down. The motors 16 on the same side need to run synchronously to ensure that the two struts 17 rotate at the same angle and keep the moving frequencies of both ends of the armrest 15 the same. After the wheelchair is fixed to the edge of the hospital bed, one side of the armrest 15 is put down, so that the wheelchair is combined with the hospital bed, facilitating the patient to move onto the hospital bed. It solves the inconvenience and safety risks caused by the need for a short landing when the patient transfers between the hospital bed and the wheelchair.
[0058] In one embodiment, please refer to Figure 6 , a groove 150 is provided at the end of the armrest 15, and a control button 26 is provided in the groove 150.

[0066] The specific use process of the present invention is as follows:
[0067] When moving the patient from the wheelchair to the hospital bed, move the side of the wheelchair to fit against the edge of the bed. By activating the second electric push rod 25, the second electric push rod 25 drives the mounting plate 20 to rotate, so that the mounting plate 20 rotates from the vertical state to the horizontal state, and both ends of the mounting plate 20 are in contact with the bottom surface of the hospital bed. Then start the first motor, so that the first motor drives two synchronous belts to rotate, and then drives two bidirectional screws 22 to rotate synchronously through the synchronous belts. The bidirectional screws 22 drive two clamping plates 23 to slide towards the middle of the chute 21 to clamp the bed frame, thereby fixing the wheelchair and the hospital bed together. Start the second motor 16 on the side close to the hospital bed, and control the strut 17 to rotate through the second motor 16, so that the strut 17 drives the armrest 15 to tilt downwards, and finally the armrest is parallel to the edge of the bed. At the same time as the second motor 16 is started, start the first electric push rod 14, so that the back plate 11 and the side plate 12 rotate to the horizontal state and are parallel to the bed body, and the patient can directly move onto the hospital bed, avoiding the inconvenience and accidental risks brought by short-term getting out of bed and walking.
[0068] When the patient is performing upper limb training, take out the handle 31 from the storage box 33, align the card slot 323 of the handle 31 with the convex block 320 and insert it. Under the action of the force on the inclined surface, the clamping block 322 contracts into the concave hole 321, so that the spring is compressed. After the handle 31 moves to the braking position, the clamping block 322 pops out of the concave hole 321 under the action of the spring and snaps into the card slot 323, fixing the handle 31 to the slider 30. According to the patient's usage habit, unscrew the bolt 314, move the sliding hand-held rod 312, so that the hand-held rod 312 slides left and right along the cross bar 311. After the hand-held rod moves to the designated position, it is threadedly connected with the hand-held rod 312 through the bolt 314 and passes through the screw hole 315 on the cross bar 315 to fix the hand-held rod 312 and the cross bar 311, realizing the adjustment of the distance between the two hand-held rods 312 according to the user's habit. Hold the handle 31 with both hands and push forward. The handle 31 drives the slider 30 to slide forward in the guide groove 152, driving the spring to stretch. Then release the thrust on the handle 31. Under the action of the spring, drive the slider 30 and the handle 31 to automatically reset. Repeat the operation to realize the patient's exercise of the upper limbs;
[0069] When the patient uses the wheelchair to walk on a slope, according to the induction of the inclination sensor, automatically start the third electric push rod 43 on the lower side. Under the push of the electric push rod 43, the top rod 40 and the bottom rod 41 move away from each other, raising the height of the lower side of the wheelchair seat plate to keep the patient balanced and prevent tipping over.
[0070] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.
