Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and in particular to a wearable auxiliary leg rehabilitation device. Background Art

[0002] Leg rehabilitation training has always been an important means of rehabilitation for patients. However, traditional rehabilitation training devices are mostly fixed devices, which are limited by the venue. Common wearable leg rehabilitation devices are mostly metal solids with heavy loads. They are inconvenient to wear and lead to inconvenience in movement. This makes it impossible for patients to meet their daily life exercises when they do not need leg rehabilitation training.

[0003] Therefore, we propose an invisible wearable leg rehabilitation device, which can meet the rehabilitation training needs of patients and is easy to wear and move. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides a wearable auxiliary leg rehabilitation device to reduce the weight, facilitate wearing, and facilitate daily work.

[0005] The present invention provides a wearable auxiliary leg rehabilitation device, comprising: a wearable part, the wearable part comprising a calf sleeve and a thigh sleeve; the calf sleeve can be worn on the calf, and the thigh sleeve can be worn on the thigh; a connecting part, the connecting part is arranged at the wearable part, and one end of the connecting part is connected to the calf sleeve, and the other end of the connecting part is connected to the thigh; the connecting part includes at least one flexible tube; and a driving part, the driving part is arranged on the wearable part and is used to drive the connecting part to move.

[0006] Furthermore, the wearing part further comprises a zipper; the zipper is provided at two locations, and is located at the calf sleeve and the thigh sleeve respectively. In actual use, the purpose of this design is to facilitate wearing.

[0007] Furthermore, the wearing part also includes an elastic member, which is provided at two locations and respectively located at the calf sleeve and the thigh sleeve; the elastic member includes a buckle and an elastic band; wherein the two buckles are respectively installed at the calf sleeve and the thigh sleeve and fixedly connected; and one end of the two elastic bands are respectively installed on the calf sleeve and the thigh sleeve and located in the opposite direction of the buckles, and the other end of the elastic band is detachably connected to the buckle. In actual use, the purpose of this design is to further tighten the wearing and facilitate the device to be firmly worn on the body. In this way, the calf sleeve and the thigh sleeve are prevented from falling off during rehabilitation training, and the training effect and wearing stability are further guaranteed.

[0008] Furthermore, the connection part also includes an electromagnetic wire and a mobile power source, wherein the electromagnetic wire is arranged in the flexible tube, and one end of the electromagnetic wire extends outward and is electrically connected to the mobile power source; wherein the electromagnetic wire has magnetism after being energized. In actual use, the electromagnetic wire is made of neodymium iron boron material, and a USB interface is provided on the part of one end of the electromagnetic wire extending outward, so that the mobile power source can be worn on clothing, and the USB interface is used to realize the electrical connection between the mobile power source and the electromagnetic wire.

[0009] Furthermore, the connecting part also includes a magnetic fluid, which is located in the flexible tube; wherein the magnetic fluid is adsorbed on the electromagnetic wire after the electromagnetic wire is energized. In actual use, the purpose of this design is to strengthen the flexible tube. When the electromagnetic wire is not energized, the magnetic fluid accumulates at the bottom of the flexible tube, mainly concentrated on the calf, that is, the calf sleeve; in this way, a design similar to foot weight bearing is formed; in this way, weight bearing rehabilitation is achieved; and as the strength of the conductivity of the electromagnetic wire changes, the magnetic fluid will be partially adsorbed on the electromagnetic wire that is not in the calf part; thereby causing the weight bearing of the calf to change, thereby adjusting the weight bearing change; thereby improving the scope of application. At the same time, when the magnetism of the electromagnetic wire is gradually strengthened, the magnetic fluid accumulated at the bottom of the flexible tube is all adsorbed on the electromagnetic wire. In this way, the magnetic fluid on the surface of the electromagnetic wire is closely adsorbed and gathered together under the magnetic effect; in this way, the magnetic fluid adsorbed on the electromagnetic wire strengthens the axial direction of the flexible tube; it is convenient to achieve flexion and extension movement with the flexible tube as a link. Then a variety of rehabilitation training methods are achieved.

[0010] Furthermore, the flexible tube has radial extensibility but no axial extensibility. In actual design, the flexible tube is a combination of rubber and nylon rope, wherein the nylon rope is evenly distributed in a ring shape, not a mesh shape, and the rubber is coated outside the nylon rope.

[0011] Furthermore, the driving part includes a separator, which is mounted on the calf sleeve; the separator includes a vibration motor and a fixing sleeve; one end of the flexible tube is mounted on the fixing sleeve, and the vibration motor is in contact with the fixing sleeve; before the electromagnetic wire is energized, the vibration motor is started to separate the magnetic fluid accumulated at the bottom of the flexible tube. In actual use, the purpose of this design is to prevent the magnetic fluid accumulated at the bottom of the flexible tube from being quickly adsorbed on the electromagnetic wire when the electromagnetic wire is energized; in actual work, the vibration generated by the vibration motor reduces the aggregation effect of the magnetic fluid after vibration, achieves dispersion, and makes it more convenient for the magnetic fluid to be adsorbed to the electromagnetic.

[0012] Furthermore, the driving part also includes a main driving part, which is installed on the thigh sleeve; the main driving part includes a screw sleeve, a screw nut and a motor; the other end of the flexible tube is fixedly installed in the screw sleeve; the screw sleeve has a screw thread section, and the screw nut is rotatably installed on the screw sleeve and is located on the screw thread section; the screw nut is connected to the motor drive. In actual use, the purpose of this design is to achieve axial reciprocating motion of the flexible tube. The design adopted is a screw transmission method. The motor drives the screw nut to rotate, and then the screw sleeve moves axially on the screw nut, thereby driving the flexible tube to move; in this way, flexion and extension motion is achieved. At the same time, through the main driving parts set on multiple flexible tubes, flexion and extension motion in different directions is achieved through the different speeds of multiple motors, thereby facilitating rehabilitation training.

[0013] It can be seen from the above technical solution that the beneficial effects of a wearable auxiliary leg rehabilitation device provided by the present invention are:

[0014] (1) In actual use, the wearable material of the design is a cotton-like material that is woven close to the body; this makes it easy to wear and use;

[0015] (2) At the same time, the flexible tubes in the connecting part are provided with a plurality of tubes, so that it is convenient to connect the calf sleeve and the thigh sleeve together;

[0016] (3) When the flexible tube is driven, the calf sleeve can move relative to the thigh sleeve, and then the calf can move relative to the thigh, so that leg rehabilitation training can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

In actual use, the material of the wearable part 1 of this design is a woven close-fitting cotton material; this makes it easy to wear and use; at the same time, the flexible tubes 21 in the connecting part 2 are provided with multiple roots, so that it is convenient to connect the calf sleeve 11 and the thigh sleeve 12 together; when the flexible tube 21 is driven, the calf sleeve 11 can move relative to the thigh sleeve 12, and then the calf can move relative to the thigh, so that leg rehabilitation training can be achieved.

[0033] At the same time, in order to facilitate wearing, in this embodiment, the wearing part 1 also includes a zipper 13; the zipper 13 is provided at two locations, and is respectively located at the calf sleeve 11 and the thigh sleeve 12. In actual use, the purpose of this design is to facilitate wearing. And in order to further facilitate wearing, in this embodiment, the wearing part 1 also includes an elastic member 14, and the elastic member 14 is provided at two locations, and is respectively located at the calf sleeve 11 and the thigh sleeve 12; the elastic member 14 includes a buckle 141 and an elastic band 142; wherein the two buckles 141 are respectively installed at the calf sleeve 11 and the thigh sleeve 12, and are fixedly connected; and one end of the two elastic bands 142 is respectively installed on the calf sleeve 11 and the thigh sleeve 12, and is located in the opposite direction of the buckle 141, and the other end of the elastic band 142 is detachably connected to the buckle 141. In actual use, the purpose of this design is to make the wearing more tight and convenient for wearing the device firmly on the body. In this way, the calf sleeve 11 and the thigh sleeve 12 are prevented from falling off during rehabilitation training, and the training effect and wearing stability are further guaranteed.

[0034] At the same time, in order to achieve better connection strength, in this embodiment, the connection part 2 also includes an electromagnetic wire 22 and a mobile power supply 23. The electromagnetic wire 22 is arranged in the flexible tube 21, and one end of the electromagnetic wire 22 extends outward and is electrically connected to the mobile power supply 23; wherein the electromagnetic wire 22 has magnetism after being energized. In actual use, the electromagnetic wire 22 is made of neodymium iron boron material, and a USB interface 201 is provided on the part of the electromagnetic wire 22 extending outward at one end. At that time, the mobile power supply 23 can be worn on clothing, and the mobile power supply 23 can be electrically connected to the electromagnetic wire 22 through the USB interface 201. In order to further strengthen the strength of the flexible tube 21, in this embodiment, the connection part 2 also includes a magnetic fluid 24, and the magnetic fluid 24 is located in the flexible tube 21; wherein after the electromagnetic wire 22 is energized, the magnetic fluid 24 is adsorbed on the electromagnetic wire 22. In actual use, the purpose of this design is to strengthen the flexible tube 21. When the electromagnetic wire 22 is not energized, the magnetic fluid 24 accumulates at the bottom of the flexible tube 21, mainly concentrated on the calf, that is, the calf sleeve 11; in this way, a design similar to the weight-bearing of the foot is formed; in this way, weight-bearing rehabilitation is achieved; and as the strength of the conductivity of the electromagnetic wire 22 changes, the magnetic fluid 24 will be partially adsorbed on the electromagnetic wire 22 that is not in the calf; thereby, the weight of the calf changes, and the weight change is adjusted; thereby, the scope of application is improved. At the same time, when the magnetism of the electromagnetic wire 22 is gradually strengthened, the magnetic fluid 24 accumulated at the bottom of the flexible tube 21 is all adsorbed on the electromagnetic wire 22. In this way, the magnetic fluid 24 on the surface of the electromagnetic wire 22 is closely adsorbed and gathered together under the magnetic effect; in this way, the magnetic fluid 24 adsorbed on the electromagnetic wire 22 strengthens the axial direction of the flexible tube 21; it is convenient to achieve flexion and extension movement with the flexible tube 21 as a link. Thus, a variety of rehabilitation training methods are achieved. The mobile power source 23 can be purchased directly with an adjustable power supply, or a controller can be installed.

[0035] In this embodiment, the flexible tube 21 has radial extensibility but no axial extensibility. In actual design, the flexible tube 21 is a combination of rubber 211 and nylon rope 212 ; the nylon rope 212 is evenly distributed in a ring shape, not a mesh shape; and the rubber 211 is wrapped around the nylon rope 212 .

In actual use, the purpose of this design is to prevent the magnetic fluid 24 accumulated at the bottom of the flexible tube 21 from being quickly adsorbed on the electromagnetic wire 22 when the electromagnetic wire 22 is energized; in actual work, the vibration generated by the vibration motor 311 reduces the aggregation effect of the magnetic fluid 24 after vibration, and achieves dispersion, which makes it more convenient for the magnetic fluid 24 to be adsorbed to the electromagnetic wire.

[0037] At the same time, in order to achieve driving, in the present embodiment, the driving part 3 also includes a main driving component 32, and the main driving component 32 is installed on the thigh sleeve 12; the main driving component 32 includes a screw sleeve 321, a screw nut 322 and a motor 323; the other end of the flexible tube 21 is fixedly installed in the screw sleeve 321; the screw sleeve 321 has a screw thread section 3221, and the screw nut 322 is rotatably installed on the screw sleeve 321 and is located on the screw thread section 3221; the screw nut 322 is drivingly connected to the motor 323. In actual application, the purpose of this design is to realize the axial reciprocating motion of the flexible tube 21. The design adopted is a screw transmission method. The motor 323 drives the screw nut 322 to rotate, so that the screw sleeve 321 moves axially on the screw nut 322, thereby bringing the flexible tube 21 to move; in this way, flexion and extension motion is realized. At the same time, through the main drive parts 32 set on multiple flexible tubes 21 and the different rotation speeds of multiple motors 323, flexion and extension motion in different directions is realized, thereby facilitating rehabilitation training.

When it is necessary to perform flexion and extension rehabilitation training, the motor 323 is powered on to rotate, and its forward and reverse rotation is adjusted to realize the axial reciprocating motion of the flexible tube 21, and then the movement of the calf sleeve 11 relative to the thigh sleeve 12 is realized, so that the leg flexion and extension rehabilitation exercise is realized.
