Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a nursing robot used for transporting sick and injured persons. Background Art

[0002] Intra-hospital transfer refers to the necessary transfer process of patients between various departments within the hospital according to various needs.

[0003] Chinese patent CN110812009A (application number: 201911142064.4) discloses a "medical transport nursing robot". In its embodiment, the driving motor 1 is started in the forward direction. Through the bed board driving assembly, the moving bed board is extended under the drag of the toothed belt drive connecting seat, and the bed board belt wrapped thereon is extended synchronously. At this time, the electric roller remains stationary, so that the bed board belt and the belt shaft I, belt shaft II, belt shaft III, and the electric roller The part connected remains stationary, and the front end extends with the extension of the moving bed board. The extended part is supplemented by the part stored between the belt shaft II and the roller. The bed board belt and the front end of the moving bed board form a relative motion similar to a conveyor belt when extending. When the moving bed board is extended under the patient's body, in this conveyor-like Under the action of the same relative movement as the belt, the patient is loaded onto the mobile bed board, and then the manned return stage is entered. At this time, the driving motor reverses, and the mobile bed board and the bed board belt retract synchronously. To ensure that the patient and the mobile bed board are relatively still, the electric roller rotates clockwise, and the retracted bed board belt is stored between the belt reel shaft II and the roller. When the mobile bed board is fully returned, the driving motor and the electric roller stop at the same time. However, due to the shortage of beds in the hospital and the small space in some departments, and the mobile bed board is restricted by the electric roller, the edge of the mobile bed can only be moved out along one end of the bed body, resulting in one-way transportation. The use conditions are limited, and the bed body needs to be adjusted, which leads to an overall extension of the transportation time, delays the patient's condition, and cannot meet the actual needs of use.

[0030] More preferably, before receiving the lying board 10, the second servo motor 13 drives one of the driving gears 2 to rotate, and under the action of the meshing toothed belt 3, the two driving gears rotate at the same time. Under the rotation of the two driving gears 2, the meshing toothed belt 3 drives the transmission box seat 4 to slide along the annular guide rail 101 on the surface of the table plate 1 through the connecting hinge seat 301, so that multiple transmission box seats 4 are distributed on both sides or both ends of the table plate 1, and the first servo motor 6 located at the bottom of the transmission box seat 4 drives the active guide roller 5 to rotate through the transmission belt 7, and cooperates with the auxiliary guide roller 9 on the surface of the additional plate 8, so that the lying board 10 gradually moves from both sides or both ends of the table plate 1 to the center. When the infrared sensor 14 located inside the positioning plate 12 senses the positioning mark 1003 on the back of the lying board 10, the cylinder 11 drives the positioning plate 12 to extend and insert into the notch 1002 on the back of the lying board 10, so as to limit the position of the lying board 10 and prevent the lying board 10 from moving;

[0031] When the lying board 10 is pushed horizontally, multiple transmission box seats 4 are distributed on the left and right sides of the table plate 1. The first servo motor 6 located at the bottom of the transmission box seat 4 drives the active guide roller 5 to rotate through the transmission belt 7, and cooperates with the auxiliary guide roller 9 on the surface of the additional plate 8, so that the lying board 10 is gradually moved horizontally from one side of the table plate 1 to the other side.

[0032] When it is necessary to push the lying board 10 forward or backward, the lying board 10 needs to be lifted first. When multiple transmission box seats 4 move to the front and rear ends of the table plate 1 respectively, the lying board 10 is put down, and the first servo motor 6 located at the bottom of the transmission box seat 4 drives the active guide roller 5 to rotate through the transmission belt 7, and cooperates with the auxiliary guide roller 9 on the surface of the additional plate 8, so that the lying board 10 is gradually moved longitudinally from one end of the table plate 1 to the other end.

[0033] In this embodiment, Figure 1 The longitudinal direction of the top board 10 is set as the front-back direction, and the width direction is set as the left-right direction.
