[0020] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0021] This rehabilitation robot features an adjustable electric actuator on its back panel that drives the telescopic measurement component to move, thereby adjusting the tension (traction force) of the traction rope. It can flexibly switch according to the user's rehabilitation progress (such as initial light traction and intermediate intensive training), avoiding excessive force that could cause secondary injury or insufficient force that could affect the rehabilitation effect. The telescopic measurement component (hollow plate + limit plate with round hole) not only stably fixes the traction rope, but also indirectly judges the range of motion of the limb by the extension length of the traction rope, and helps to record quantitative data of rehabilitation training (such as the distance of arm / leg traction extension), which makes it convenient for users or caregivers to assess the recovery progress. Moreover, the fixing components can fix the limbs and waist and other structures, and complete traction rehabilitation in various positions, making it more adaptable.

[0022] This rehabilitation and nursing robot features a dual-remote control design, covering both "sitting" and "foot" operation scenarios. The adjustable design includes a counterweight plate, movable plate, and brake casters. The tilting electric push rod and lifting pulley can assist in adjusting the tilt angle of the leg plate and seat plate (such as lifting one side of the seat plate to achieve a slight tilt, making it easier for users to get up or adjust their sitting posture), adapting to various usage needs.

[0023] This rehabilitation and nursing robot is capable of multiple adjustments to meet various rehabilitation needs and has a wide range of applications. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0036] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0037] The connection method can adopt existing methods such as bonding, welding, and bolting, depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0038] Please see Figures 1 to 5 As shown, a rehabilitation nursing robot, in this embodiment, includes:

[0039] Seat board 1 is used to support people who require rehabilitation care;

[0040] Leg plate 2 and back plate 3 are rotatably connected to both sides of seat plate 1. Two guide pulleys 4 are connected to the side of back plate 3. The outer periphery of the guide pulleys 4 is wrapped with traction rope 5 for rehabilitation care. Two adjustable electric push rods 6 are installed on the back of back plate 3. The moving part of the adjustable electric push rod 6 is connected to the telescopic measuring component 7. The telescopic measuring component 7 is connected and fixed to the traction rope 5. The other end of the traction rope 5 is connected to the fixation component 8 for fixing the limb. The fixation component 8 is a flexible strap that can be adapted to different limb parts (such as wrist, ankle, knee joint) or different limb sizes (such as children's ankle, adult knee joint). The fixation component 8 has reserved interfaces for rehabilitation training accessories (such as grip ball fixing groove, elastic band hook) to meet the patient's needs for mild upper limb rehabilitation training in a sitting position (such as grip strength training, elbow flexion and extension training).

[0041] The support component 9 is connected to the bottom of the seat plate 1. Two rotating plates 10 are rotatably connected to the side of the leg plate 2. A foot pedal remote control 11 is connected to the side of the rotating plate 10. A hand-held remote control 12 is also provided at the top of the seat plate 1. Two armrests 13 are connected to the top of the seat plate 1. The surface is provided with anti-slip texture (to prevent the patient's palms from sweating and slipping). The user can operate by holding the hand remote control 12 or the foot pedal remote control 11. When adjusting the angle of the back plate 3 and the leg plate 2, the tilting electric push rod 96 at the top of the movable plate 93 is activated. Its moving part drives the lifting pulley 97 to lift a part of the seat plate 1, causing the structure to rotate around the seat plate 1 to meet different needs such as sitting and semi-reclining. During the process, the armrests 13 provide balance support for the user.

[0042] Support component 9 includes:

[0043] All four support legs 91 are connected to the bottom end of the seat plate 1;

[0044] The counterweight plates 92 are all connected to the bottom ends of the four support legs 91. Movable plates 93 are provided on both sides of the counterweight plates 92. Multiple brake casters 94 are connected to the bottom ends of both the counterweight plates 92 and the movable plates 93. Four circular channels are opened on the side of the counterweight plates 92, and sliding rods 95 passing through these circular channels are connected to the side of the movable plates 93. Multiple tilting electric actuators 96 are installed at the top of the movable plates 93. The number and position of the tilting electric actuators 96 are not specified in the diagram, but are used to ensure the stability of the support. The moving parts of the tilting electric actuators 96 are connected to lifting pulleys 97. The top of the counterweight plates 92 has openings that connect to the circular channels. The threaded channel is connected to a threaded rod 98 for fixing the slide rod 95. The support assembly 9 at the bottom of the base plate 1 provides a stable base for the equipment. Four support legs 91 connect the base plate 1 to the counterweight plate 92. The counterweight plate 92 enhances the overall stability of the equipment and prevents it from tipping over. When the position of the equipment needs to be adjusted, the brake caster 94 can be released to push it to move. When fixed, the caster is locked. If it is necessary to expand the support area, the movable plate 93 can be pulled to make the slide rod 95 extend along the circular channel of the counterweight plate 92. Then, the threaded rod 98 is turned to fix the slide rod 95, which improves the stability of the equipment in different environments.

[0045] This application is applicable to flat surfaces, such as indoor spaces without thresholds, and is not suitable for outdoor operation.

[0046] The telescopic measurement component 7 includes:

[0047] Hollow plate 71 is connected to the side of the moving part of the adjusting electric actuator 6;

[0048] A limiting plate 72 is set inside the hollow plate 71. A circular hole is opened on the side of the limiting plate 72 for attaching the traction rope 5. A pressure sensor 73 is installed on the side of the moving part of the adjusting electric push rod 6. A spring 74 is connected between the measuring part of the pressure sensor 73 and the movable plate 93. The limb is connected to the traction rope 5 through the fixing part 8. When the adjusting electric push rod 6 is activated, its moving part drives the telescopic measuring component 7 to move. The traction rope 5 pulls the limb under the guidance of the guide pulley 4 to achieve traction rehabilitation. The hollow plate 71 and the limiting plate 72 of the telescopic measuring component 7 ensure the stability of the traction rope 5. At the same time, the range of motion of the limb can be judged by the telescopic length of the traction rope 5. The pressure sensor 73 monitors the traction pressure in real time. If the pressure exceeds the threshold, the spring 74 buffers and triggers the sensor signal to control the adjusting electric push rod 6 to adjust, avoid over-traction, and ensure training safety.

[0049] The number of pressure sensors 73 is affected by factors such as the friction of the guide pulley 4, but the effect is actually readjusted based on the operation of medical staff and the feedback of the rehabilitation nurses.

[0050] In order to improve the adjustment range and reduce costs, this application uses manual adjustment for some structures. When the user is an elderly person living alone, a person with weak limb function, or a caregiver who needs to take care of the patient at the same time, the manually adjustable parts of the structure need to be replaced with electrically adjustable structures.

[0051] The electric actuator 6, foot remote control 11, hand remote control 12, pressure sensor 73, and tilting electric actuator 96 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0052] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0053] This rehabilitation and nursing robot is based on the core principles of "stable support, autonomous operation, and controllable rehabilitation." It achieves posture adjustment and safe rehabilitation training through the linkage of its various components. The specific working principle is as follows:

[0054] In terms of basic support and movement, the support component 9 at the bottom of the base plate 1 provides a stable base for the equipment. The four support legs 91 connect the base plate 1 and the counterweight plate 92. The counterweight plate 92 enhances the overall stability of the equipment and prevents it from tipping over. When the position of the equipment needs to be adjusted, the brake caster 94 can be released to push it to move. When fixed, the caster is locked. If it is necessary to expand the support area, the movable plate 93 can be pulled so that its sliding rod 95 extends along the circular channel of the counterweight plate 92. Then, the threaded rod 98 is tightened to fix the sliding rod 95, thereby improving the stability of the equipment in different environments.

[0055] In the posture adjustment process, the user can operate the remote control 12 by hand or the foot remote control 11 to adjust the angle of the back panel 3 and the leg panel 2. When the user adjusts the angle of the back panel 3 and the leg panel 2, the tilting electric push rod 96 at the top of the movable plate 93 is activated. Its moving part drives the lifting pulley 97 to lift a part of the seat plate 1, causing the structure to rotate around the seat plate 1 to meet different needs such as sitting or reclining. During the process, the armrest 13 provides balance support for the user.

[0056] Rehabilitation traction training is the core function. In use, the limb is connected to the traction rope 5 through the fixing part 8, and the adjusting electric push rod 6 is activated. Its moving part drives the telescopic measurement component 7 to move. The traction rope 5 pulls the limb under the guidance of the guide pulley 4 to achieve traction rehabilitation. The hollow plate 71 and the limiting plate 72 of the telescopic measurement component 7 ensure the stability of the traction rope 5. At the same time, the range of motion of the limb can be judged by the telescopic length of the traction rope 5. The pressure sensor 73 monitors the traction pressure in real time. If the pressure exceeds the threshold, the spring 74 buffers and triggers the sensor signal to control the adjusting electric push rod 6 to adjust, avoid over-traction, and ensure training safety.

[0057] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
