[0040] The oblique rod 57 is located on the displacement track of the trigger rod 54. A blocking rod 512 is fixedly connected to the side of the robot body 1. The blocking rod 512 is located on the displacement track of the handrail rod 59. The blocking rod 512 can block the handrail rod 59 to prevent the handrail rod 59 from hitting the patient.

[0041] A specific application of this embodiment is: during the nursing process, the patient may have difficulty walking and needs to be helped by a walking assistant. Manual nursing assistance affects the efficiency of movement, while using a robot-driven walking assistant reduces the workload of the nursing staff. The patient is helped onto the support rod 314 and sits on the cushion plate 53, with the backrest plate 33 used for support. Since the height of each patient is different, the required support angle of the backrest plate 33 is also different. Therefore, the support angle of the backrest plate 33 needs to be adjusted to provide the patient with more comfortable nursing. The motor 36 is started, and the rotation of the motor 36 drives the gear 37 to rotate. The gear 37 and the rack 39 are meshed with each other. When the gear 37 rotates, it drives the rack 39 to slide on the side of the support plate 38. The rack 39 slides The connecting rod 310 and the squeezing rod 311 will be driven to move. The rotating rod 32 is located on the displacement trajectory of the squeezing rod 311. When the motor 36 rotates forward and drives the rack 39 to move upward, the squeezing rod 311 will move upward. The squeezing rod 311 will move upward and squeeze the rotating rod 32 from bottom to top, and the rotating rod 32 will be rotated upward, driving the backrest board 33 to rotate upward for angle adjustment. The robot can replace manual support for patients, reduce the physical exertion of caregivers, and enable them to focus on other care tasks. The robot automatically adjusts the support angle of the backrest board 33 according to the patient's height and body shape, provides a personalized comfort experience, reduces discomfort, and uses the combination of the backrest board 33 and the cushion to provide patients with stable support and help them stay safe and comfortable during movement.

[0042] By rotating the motor 36 mentioned above, the motor 36 will drive the connecting belt 44 to rotate, and the connecting belt 44 will drive the threaded rod 43. The rotation of the threaded rod 43 will drive the threaded sleeve 45 to move on the threaded rod 43. The movement of the threaded sleeve 45 will drive the cross bar 46 to slide on the inner wall of the slide groove 47. The movement of the slide groove 47 will drive the scraping brush 48 to move. The touch screen 2 is located on the movement trajectory of the scraping brush 48. When the scraping brush 48 moves, it will scrape the surface of the touch screen 2 to remove dust on the surface of the touch screen 2 of the robot body 1. The cleaning of the touch screen 2 by the scraping brush 48 can effectively remove dust and dirt, keep the screen clean, avoid blurred vision or insensitive robot touch caused by dirt, and reduce bacterial growth. Especially in a nursing environment, keeping equipment hygienic is an important measure to protect the health of patients. A clear touch screen 2 helps to improve the convenience and accuracy of operation, and users have a better experience and smoother operation when using it.

[0043] Through the above, the patient needs to sit on the cushion board 53. The bottom of the cushion board 53 is provided with a telescopic rod 52 and a spring 51. When the patient sits on the cushion board 53, gravity will be generated on the cushion board 53, squeezing the cushion board 53 downward, which will cause the cushion board 53 to move downward. The downward movement of the cushion board 53 will drive the trigger rod 54 to move downward. The inclined rod 57 is located on the movement trajectory of the trigger rod 54. When the trigger rod 54 moves downward, it will squeeze the inclined rod 57. The inclined rod 57 is squeezed to move downward, and the downward movement of the inclined rod 57 drives the turntable 56 to rotate downward, and the downward rotation of the turntable 56 drives the support rod 58 and the handrail rod 59 to rotate downward, and the cushion plate 53 is located on the movement track of the handrail rod 59, and the handrail rod 59 is located on both sides of the cushion plate 53. At this time, the patient is sitting on the cushion plate 53. When the handrail rod 59 rotates downward, it will move closer to the two sides of the cushion plate 53, so that the handrail rod 59 rises and stands on the cushion plate 53. On both sides, armrest support is provided for the patient sitting on the cushion plate 53. During the rotation of the armrest rod 59, the blocking rod 512 will block the armrest rod 59 to prevent the patient from being hit by the armrest rod 59 when it rotates. When the patient sits on the cushion plate 53 and uses the robot to drive the robot for transportation, the armrest rod 59 automatically rises to provide armrests for the patient, preventing the patient from shaking when the robot moves, and reducing the risk of accidentally falling from the robot. The automatic rising design of the armrest rod 59 provides additional support for the patient and reduces the risk of falling due to body shaking during movement. This is especially important for patients with limited mobility and can effectively improve their sense of security. By providing stable support, patients can feel more autonomy and independence when using the robot, and can perform daily activities more confidently. Providing armrests is not only physical support, but also can give patients psychological comfort and a sense of security, making them more relaxed when using the equipment.
