Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The medical care mattress shown in the attached figure 1 comprises a mattress framework and a flexible pad 5, wherein the mattress framework comprises two groups of longitudinally arranged turnover assemblies, and each turnover assembly comprises a deformable framework 1 and a driving assembly 2.

The deformable framework 1 is a long chain which is composed of a plurality of chain links 11 on a straight line and extends along the horizontal direction. In the initial state, all the links 11 are arranged in a straight line, any adjacent links 11 are hinged with each other, and each link 11 can only rotate upwards relative to its adjacent link 11 (i.e. one link 11 in two adjacent links 11 can only tilt upwards relative to the other link 11).

Deformable frameworks 1 of two groups of longitudinally arranged turnover assemblies are parallel to each other, a support strip array formed by a plurality of support strips 6 is erected between the two groups of deformable frameworks 1, two ends of each support strip 6 are respectively fixed on corresponding chain links 11 of the two groups of deformable frameworks (namely two ends of each support strip 6 are arranged on two chain links 11 positioned on the same transverse line), the support strips 6 can be arranged on each chain link 11 on the deformable frameworks 1, and one support strip 6 can be arranged on the chain links 11 of each fixed number of chain links 11 at intervals; the driving assembly can move back and forth along the deformable framework and can drive any two adjacent links in the deformable framework to rotate relatively; the flexible mat 5 rests on the array of support bars. The array of support bars provides effective support for the flexible mat 5 so that the user does not sag significantly when lying on the flexible mat 5.

Specifically, each link 11 has a protrusion 112 and a notch 113, the protrusion 112 of one link 11 of two adjacent links 11 is hinged to the notch 113 of the other link 11, the lower side of the notch 113 is provided with a stop 114, and the stop 114 abuts against the lower side of the protrusion 112 of the other link 11, so as to prevent the one link 11 of two adjacent links 11 from rotating downward relative to the other link 11.

The driving assembly 2 can move back and forth along the deformable skeleton 1 and can drive the relative rotation between any two adjacent chain links 11 in the deformable skeleton 1, so that one chain link 11 in the two adjacent chain links 11 rotates relative to the other chain link 11.

By adopting the structure, the synchronous movement of the two groups of turnover assemblies is controlled, namely the driving assemblies 2 of the two groups of turnover assemblies are controlled to synchronously execute operation, one sides of the two deformable frameworks 1 can be synchronously turned over and tilted, so that one part of the flexible cushion 5 is driven to tilt, a user lying on the flexible cushion 5 can sit up, the position where the deformable frameworks 1 are turned over is determined according to the position of the waist of the user, and thus the position of the user on the flexible cushion 5 can be arranged without being adjusted in advance, and the user can sit up.

Specifically, the driving assembly 2 comprises a linear transmission assembly 21 and a folding executing assembly 22, wherein the linear transmission assembly 21 is used for enabling the driving assembly to integrally move along the length direction of the deformable framework 1; the folding actuating assembly 22 is used for driving the relative rotation between any two adjacent links 11 in the deformable framework 1.

In the above-mentioned solution, the user can sit up, further, in order to turn over the body of the user, at least one other group of transversely arranged turnover assemblies may be arranged between the two longitudinally arranged turnover assemblies, in this embodiment, there are two groups of transversely arranged turnover assemblies, and correspondingly, the flexible cushion 5 is composed of three cushion bodies 51; the cushion bodies 51 are arranged on two sides of each transversely arranged turnover assembly, and a movement space of the turnover assembly is reserved between the cushion bodies 51 on the two sides of the turnover assembly, so that the part of the deformable framework 1 can be lifted without blocking. By controlling the movement of the deformable skeleton 1 of the transverse turnover assembly, one section of the deformable skeleton 1 of the transverse turnover assembly can be tilted, a user on the flexible cushion 5 is driven to lie on the side instead of lying on the flat side, and the turnover position of the deformable skeleton 1 is determined and adjusted by the position of the user. Further, transversely set up all be equipped with flexible filler strip 7 on the flexible skeleton 1 of rolling over the subassembly, transversely set up like this the flexible skeleton 1 of rolling over the subassembly contacts with the user through flexible filler strip 7, can improve experience, can not press against the injury user.

The folding actuating assembly 22 includes an assembly base 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 motor 223 corresponds to the folding rod 222, and there are two of the folding rods 222, and is used for driving the folding rod 222 to rotate relative to the component seat 221.

Each link 11 has a tooth 111 thereon, so that the deformable skeleton 1 has a continuous array of 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 chain link 11 and prevent the component seat and the chain link from having a large play gap from the up, down, left and right, a roller 12 is arranged on each chain link 11, and the rotating shaft of each roller 12 is parallel to the relative rotating shaft between adjacent chain links 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 assembly seat 221 and the link 11 can be restricted.

The left and right sides of each chain link 11 are provided with balls 13, the assembly seat 221 has two side plates 221-2, and when the assembly seat 221 moves to a certain chain link 11, the balls 13 on both sides of the chain link 11 are pressed against the inner sides of the two side plates 221-2. In this way, the right-left relative position of the assembly seat 221 and the link 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 chain links 11 along the way along with the walking of the driving assembly 2, prevent the chain links 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 flexible robot is reliable in overall operation. In this embodiment, the guide unit 4 is mounted on the assembly base 221.

In practical use, the folding device further comprises a frame body 8, and the guide rail 3 of each folding assembly is fixed on the frame body 8.
