Therefore, the above terms should not be understood as limitations on the present invention.

[0033] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example

[0034] See also Figures 1 - 5 , a transport mechanism of a rehabilitation nursing robot, comprising: a main body support 1, on which a first support part 2, a second support part 4 and a third support part 6 are arranged, the first support part 2 is used to support the buttocks, ensuring that the buttocks of the patient are fully supported during the transport process, avoiding discomfort and pain caused by the buttocks being suspended or insufficiently supported; the second support part 4 supports the upper body of the patient, including the back, shoulders and arms, etc., which helps to keep the upper body of the patient stable and prevent shaking or tilting during the transport process; in the transport mechanism, the support for the waist is particularly important, because the waist is an important support point of the human body, and lack of sufficient support may cause the patient to lose balance and increase the risk of falling. Through sufficient support, it is avoided that the waist muscles and joints of the patient need to bear more loads to maintain body balance;

[0035] A transport mechanism of a rehabilitation nursing robot, comprising: a driving assembly, the driving assembly being arranged on both sides of a first support portion 2 and a second support portion 4, and being used to actuate the movement of components when the second support portion 4 rotates, thereby achieving the effect of synchronous operation of the components;

[0036] A transfer mechanism of a rehabilitation nursing robot includes: a groove 9, which is opened through a second support part 4 at the connection near a first support part 2, and a stopper 16 driven by a driving component to extend and retract is arranged in the groove 9. When the patient performs rehabilitation exercises or is transferred, the position of the stopper 16 is dynamically adjusted as needed, which can better support and protect the patient's body parts and reduce the discomfort caused by fixed support.

[0037] Among them, the body support 1 consists of a support frame and driving wheels. The driving wheels enable the transfer mechanism to move flexibly on different ground surfaces, facilitating the transfer tasks in different scenarios. By controlling the rotation of the driving wheels, medical staff can conveniently manipulate the moving direction and speed of the transfer mechanism. Both ends of the first support part 2 are rotatably connected to the ends of the second support part 4 and the third support part 6 respectively. This design enables the transfer mechanism to make certain adjustments according to the patient's body shape and posture during the transfer process, improving adaptability. While maintaining flexibility, the rotational connection also ensures the relative stability between the support parts, preventing patient discomfort or safety risks caused by shaking. Soft pads 8 are laid on the first support part 2, the second support part 4, and the third support part 6. The laying of the soft pads 8 provides a softer and more comfortable support surface for the patient, reducing pain and discomfort caused by long-term contact with hard materials.

[0038] It should be added that the first support part 2 is fixedly arranged on the body support 1, and an armrest 3 that can be adjusted up and down is arranged on the first support part 2. Patients can adjust the armrest 3 to find the most suitable support position for themselves, thus enhancing the comfort during the transfer process. A housing 5 is arranged at the bottom of the second support part 4. The housing 5 is arranged on one side of the groove 9 and is used to cover the groove 9, protecting the driving components and the abutting block 16 in the groove 9 from being eroded by external impurities such as dust and moisture, and extending the service life of the device. An adjustable footrest 7 is arranged at one end of the third support part 6 away from the first support part 2. The height and angle of the footrest 7 can be adjusted according to the specific needs of the patient, meeting the personalized needs of different patients. By adjusting the position and angle of the footrest 7, patients can find the most suitable support method for themselves, thus enhancing the comfort during the transfer process.

[0039] Furthermore, the driving component includes a first rotating shaft 10. The first rotating shaft 10 penetrates through the first support part 2 and the second support part 4, and the second support part 4 rotates around the first rotating shaft 10. The second support part 4 can rotate or tilt around the first rotating shaft 10 to adapt to the body shape and posture requirements of different patients. Gear wheels 11 are arranged at both ends of the first rotating shaft 10. The first rotating shaft 10 not only serves as the central axis of rotation but also as a part of the transmission mechanism.

[0040] Furthermore, the driving assembly further includes a second rotating shaft 12, which is rotatably arranged through the second supporting part 4 and penetrates through the groove 9. Both ends of the second rotating shaft 12 are provided with second gears 13, and the second gears 13 are meshed with the first gears 11. The outer surface of the second rotating shaft 12 is symmetrically provided with third gears 14. When the second supporting part 4 rotates, the second gears 13 start to rotate along the first gears 11, and at the same time, the second rotating shaft 12 rotates synchronously. Since the third gears 14 are fixedly arranged on the outer surface of the second rotating shaft 12, the third gears 14 rotate accordingly. Since the driving assemblies are symmetrically arranged on the second rotating shaft 12, the mechanism runs stably during operation, which helps to balance the forces and torques in all directions and reduce the vibration and offset caused by imbalance. Medical staff can precisely control the patient's posture by controlling the rotation angle and speed of the first rotating shaft 10 and the second rotating shaft 12, thereby improving the patient's comfort level.

[0041] It is worth mentioning that a limiting block 15 is fixedly arranged in the groove 9, and the outer surface of the limiting block 15 is slidably connected with the abutting block 16. The abutting block 16 is restricted by the limiting block 15, so that the abutting block 16 can slide on the limiting block 15. The side of the abutting block 16 close to the soft pad 8 is set to be arc-shaped. This design enables the abutting block 16 to provide better adaptability and comfort when contacting the patient's body, reducing the sense of compression and discomfort to the patient. A number of teeth 17 are symmetrically arranged on the abutting block 16, and the teeth 17 are meshed with the third gears 14. When the third gears 14 rotate, the teeth 17 meshed with them can drive the abutting block 16 to extend or retract. The gear transmission has the characteristic of accurate transmission ratio, so the accurate control of the extending or retracting position of the abutting block 16 can be realized. This helps medical staff to make personalized adjustments according to the specific conditions of the patient.
