Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The medical flexible robot shown in fig. 1-5 comprises a deformable skeleton 1 and a driving assembly 2.
The deformable skeleton 1 is composed of a plurality of supporting units 11, in an initial state, all the supporting units 11 are arranged in a straight line, the adjacent supporting units 11 are hinged with each other, and each supporting unit 11 can only rotate upwards relative to the adjacent supporting unit 11 (namely, when the deformable skeleton 1 is horizontally placed, one supporting unit 11 in two adjacent supporting units 11 can only tilt upwards relative to the other supporting unit 11); specifically, each support unit 11 has a convex end 112 and a concave end 113, the convex end 112 of one support unit 11 of two adjacent support units 11 is hinged to the concave end 113 of the other support unit 11, and a stopper 114 is disposed at the lower side of the concave end 113, and the stopper 114 can prevent the one support unit 11 of two adjacent support units 11 from rotating downwards relative to the other support unit 11.
The driving assembly 2 can move back and forth along the deformable skeleton 1 and can drive the relative rotation between two adjacent supporting units 11 in the deformable skeleton 1, so that one supporting unit 11 in the two adjacent supporting units 11 rotates relative to the other supporting unit 11.
The driving component 2 comprises a linear transmission component 21 and a turnover executing component 22, wherein the linear transmission component 21 is used for enabling the driving component 2 to integrally move along the length direction of the deformable framework 1; the folding actuator 22 is used for driving the relative rotation between two adjacent supporting units 11 in the deformable skeleton 1.
Specifically, the folding actuator 22 includes a seat 221, a folding rod 222, and a second motor 223. The linear transmission assembly 21 is mounted on the assembly seat 221; the number of the folding rods 222 is two, and the two folding rods 222 are respectively hinged at two ends of the component seat 221; the second motors 223 are corresponding to the folding rods 222, and there are two folding rods 222 for driving the folding rods 222 to rotate relative to the assembly base 221.
Each of the supporting units 11 has engaging teeth 111 thereon, so that the deformable skeleton 1 has a continuous array of engaging teeth thereon; correspondingly, the linear transmission assembly 21 includes an engaging wheel 211 and a first motor 212, the engaging wheel 211 can be in meshing transmission with the engaging tooth array; the first motor 212 is used for driving the meshing wheel 211 to rotate. The transmission mode ensures that the transmission is reliable and stable, so that the driving assembly 2 has higher walking precision.
In order to limit the relative position of the component seat 221 and the supporting unit 11, so that the component seat and the supporting unit 11 do not have large play gaps up, down, left and right, a roller 12 is arranged on each supporting unit 11, and the rotating shaft of each roller 12 is parallel to the relative rotating shaft between adjacent supporting units 11; the assembly seat 221 is provided with a guide groove 221-1, and the roller 12 can enter and exit the guide groove 221-1 and can move in the guide groove 221-1. In this way, the vertical relative position of the component holder 221 and the support unit 11 can be restricted.
The left side and the right side of each supporting unit 11 are provided with balls 13, the assembly seat 221 is provided with two side plates 221-2, and when the assembly seat 221 moves to a certain supporting unit 11, the balls 13 on the two sides of the supporting unit 11 abut against the inner sides of the two side plates 221-2. In this way, the left-right relative position of the component holder 221 and the support unit 11 can be restricted.
Guide arc plates 221-3 are arranged on two sides of the guide chute 221-1. The guide arc plates 221-3 can straighten the support unit 11 along the way along with the walking of the driving assembly 2, prevent the support unit 11 from being uneven, ensure that the meshing wheel 211 is smoothly meshed with the meshing tooth array and ensure the walking smoothness of the driving assembly 2.
In order to ensure that the driving assembly 2 does not tilt, the driving assembly further comprises a guide rail 3, and a guide unit 4 matched with the guide rail 3 is arranged on the driving assembly 2. A guide groove is formed in the guide rail 3, and the guide unit 4 is a guide wheel capable of rolling in the guide groove. Therefore, the driving component 2 does not rotate or move up and down, and the whole medical flexible robot can operate reliably. In this embodiment, the guide unit 4 is mounted on the assembly base 221.
When the foldable frame is used, the first motor 212 is controlled to rotate to enable the driving assembly 2 to integrally move to a proper position relative to the deformable frame 1, and then the second motor 223 is controlled to rotate to enable the corresponding folding rod 222 to rotate, so that a part of the supporting units 11 can rotate upwards by a required angle to perform required operation.
The medical flexible robot provided by the invention can flexibly turn and turn the deformable framework at a required position and can control the turning angle by controlling the driving assembly to walk along the deformable framework and driving the supporting unit to rotate, is convenient and flexible to operate, and can be used for performing joint rehabilitation training on paraplegics or used for a medical bed to assist patients in sitting up and turning over.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
