Description

Technical Field

[0001] This utility model relates to exoskeleton technology, specifically including a strap assembly for easy adjustment of tightness and an exoskeleton device. Background Technology

[0002] Exoskeletons can be used in many fields such as rehabilitation therapy and assistive devices. Exoskeletons need to be worn on the human body via straps. Most existing straps use flexible straps, which are then secured to the limbs using Velcro. For example, the walking assistive exoskeleton robot disclosed in patent application number 202411985596 uses leg straps composed of nylon fabric straps, sponge padding, and Velcro. The leg straps have a fixed end and an adjustable end. When worn, the fixed end and the adjustable end are respectively fixed to the leg strap plate and the leg strap plate buckle. The leg strap plate and the leg strap plate buckle can be interlocked and fixed first, and then the adjustable end of the leg strap can be pulled to make it more tightly bound to the thigh before being glued and fixed. Therefore, when it is necessary to adjust the tightness of the straps, the adjustment end must be opened first, that is, the straps must be untied first, and then the tightness can be adjusted by tightening or loosening the adjustment end. During this process, the external force on the legs and the leg straps is obvious, and the user cannot accurately perceive the tightness of the straps. It is often necessary to try several times to achieve the best binding state. Utility Model Content

[0003] The purpose of this invention is to provide a strap assembly and exoskeleton device with adjustable tightness to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a strap assembly for easy adjustment of tightness, comprising an installation part and a strap part, wherein the strap part is connected to the installation part via a first connector and a second connector at both ends; the first connector and the second connector are connected by at least two pull wires, one upper and one lower, and a pull wire retractor is provided for adjusting the tightness of each pull wire; the strap part further includes a strap body that conforms to the human body, the strap body having deformation properties in the length direction, and the tightness of the strap body can be adjusted by adjusting the pull wires.

[0005] In the above technical solution, the strap part is connected to the installation part through a first connector and a second connector. The strap part conforms to the human body and has deformation properties in the length direction. Since the first connector and the second connector are connected by a pull wire, and the length of the pull wire can be directly adjusted by the pull wire retractor, the actual length of the strap part can be adjusted by the pull wire retractor. For the strap part in the wearing state, the user does not need to untie it. The tightness of the binding can be adjusted by adjusting the pull wire retractor. The user can perceive the adjustment in real time. Therefore, the strap part can achieve the best binding state.

[0006] As a preferred embodiment, the strap body includes a series of plates with spatial gaps between adjacent plates. These plates are movably strung on the pull line. Firstly, these plates can evenly distribute the pressure generated by the pull line. Secondly, they can provide reverse support to the pull line and the entire strap body, preventing significant longitudinal deformation during use and maintaining a good binding state. Preferably, the strap body also includes an inner lining layer. This inner lining layer is disposed inside the arc-shaped surface formed by all the plates and conforms to the human body. The inner lining layer is made of a soft material. This inner lining layer can compensate for the spatial gaps between the plates, allowing the strap body to contact the human body with a continuous contact surface. Simultaneously, the inner lining layer can reduce the tightness of the strap assembly on the human body, improving comfort.

[0007] As a preferred embodiment, all first connectors are constrained connection ends, which are constrained to the first end of the mounting part; the second connectors are free connection ends, which are connected to the hanging holes at the second end of the mounting part through hooks provided at the end. Using hooks to connect the mounting part facilitates operation.

[0008] As a preferred embodiment, the first and second ends of the mounting portion have identical and symmetrical structures, each including a hanging hole. Mounting heads are provided at the upper and lower parts of both ends, with a shaft hole I coaxially arranged in the middle of the corresponding mounting head. A detachable mounting shaft is longitudinally arranged at the shaft hole I at the first end. The end of the first connector has a shaft hole II longitudinally arranged, and it is mounted on the mounting shaft through the shaft hole II. The mounting shaft can be installed in the shaft hole I at either end of the mounting portion, and the hanging holes at both ends of the mounting portion can also be adapted to hooks. Therefore, depending on the usage requirements, the first connector can be installed at either the first or second end of the mounting portion, meaning the strap assembly is not differentiated between left and right limbs and has universality.

[0009] As a preferred embodiment, the first connector is provided with a clamping part, and the mounting shaft is provided with a positioning part. In the installation state, the clamping part and the positioning part cooperate to restrict the axial degree of freedom of the mounting shaft and prevent the mounting shaft from moving axially during use.

[0010] As a preferred embodiment, two partition slits I are provided at the end of the first connector. The portion between the two partition slits I is the clamping part, which is divided into two clamping arms by the end partition slit II. A clamping hole with a reduced diameter is provided between the two clamping arms. The positioning part is an annular groove provided on the mounting shaft. In the assembled state, the clamping hole engages with the annular groove. The clamping part has a certain degree of elastic deformation, which will not affect the assembly and disassembly of the mounting shaft. Furthermore, when the annular groove reaches the clamping hole, the clamping hole automatically clamps the annular groove, achieving positioning of the mounting shaft without additional operation.

[0011] Another objective of this invention is to provide an exoskeleton device that facilitates adjustment of the tightness of the straps. To achieve this objective, this invention provides an exoskeleton device, including an exoskeleton and a strap assembly. The strap assembly adopts the aforementioned strap assembly that facilitates adjustment of tightness. After the strap assembly is strapped to the limb, the tightness of the strap is adjusted by a pull-string retractor. The user can sense the binding force in real time, thereby making the user wear the exoskeleton more comfortably.

[0012] As a preferred embodiment, the strap assembly further includes a fixing seat fixedly mounted on the exoskeleton. The mounting part is hinged to the fixing seat via a hinge seat located on its rear side, and the hinge axis of the hinge seat extends in the lateral direction. In the installed state, there is a space for movement between the mounting part and the exoskeleton, allowing the mounting part to deflect under the constraint of the hinge axis. Therefore, the strap assembly can flexibly adapt to the movement of the human body during use. Preferably, the strap assembly also includes a limiting block detachably disposed in the space for movement. In the installed state, the limiting block restricts the deflection of the mounting part, and the user can choose the installation method of the mounting part according to their needs.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figure 1 This invention provides an embodiment of a strap assembly that facilitates tightness adjustment. The main difference between this strap assembly and existing straps is that the tightness of the strap is adjusted by a pull cord 4 and a pull cord retractor 7. The pull cord 4 can be made of steel wire, and the pull cord retractor 7 can be a rotating shoe buckle, such as a rotating shoe buckle with a no-lace function. Therefore, the tightness of the binding can be adjusted by the pull cord retractor 7.

[0024] Specifically, the strap assembly includes an installation part 1 and a strap part. The two ends of the strap part are a first connector 2 and a second connector 3, which are connected by two pull wires 4, one above the other. Several aprons 5 are arranged inside the space enclosed by the pull wires 4. The pull wires 4 move through the wire holes 6 on the outer side (back) of these aprons 5. The aprons 5 used in this embodiment can evenly distribute the pressure generated by the pull wires and also serve as a support structure for the strap part. They can position the pull wires and prevent them from coming together during use, thus keeping the strap part in a good binding state. A flexible inner lining layer 8 is provided on the side of the apron 5 that is in contact with the human body. These aprons 5 are fixed to the inner lining layer 8, and a certain distance is maintained between adjacent aprons 5 to facilitate the expansion and contraction of the strap part. In this embodiment, the pull wire retractor 7 is arranged on the outside of the strap part and fixed to the apron. The middle of the pull wire 4 passes through the corresponding pull wire retractor 7. The overall strapping force of the strap assembly can be adjusted by adjusting the two pull wire retractors 7 respectively. In addition, the armor plate 5 provided in this embodiment has the feature of being wider at the top and narrower at the bottom. Therefore, the lower tensioner 7 can be adjusted independently to tighten the lower part of the strap, so that the strap can adapt to the limb characteristics.

[0025] Combination Figure 2 and Figure 3The first and second ends of the mounting part 1 have identical and symmetrical structures, both including hanging holes 13. Mounting heads 11 are provided at the upper and lower parts of both ends, and a shaft hole I12 is coaxially provided in the middle of the corresponding mounting head 11. In this embodiment, a detachable mounting shaft 14 is longitudinally provided at the shaft hole I12 at the first end. A shaft hole II 21 is longitudinally provided at the end of the first connector 2, and it is mounted on the mounting shaft 14 through the shaft hole II 21, thus constraining the first connector to the mounting part 1. The second connector 3 is a free connection end, which connects to the hanging hole 13 at the second end of the mounting part 1 through a hook 31 at its end. In this embodiment, the mounting shaft 14 can be detached and installed at the shaft hole I12 at the second end. Therefore, depending on the usage requirements, the first connector 2 can be installed at either the first or second end of the mounting part 1, meaning the strap assembly is not divided into left and right limbs and has universality.

[0026] In addition, from Figure 3 As can be seen, the mounting shaft 14 has a narrowed annular groove 15 in the middle. Correspondingly, a clamping part 22 that mates with the annular groove 15 is provided in the middle region of the end of the first connector 2, thereby constraining the axial degree of freedom of the mounting shaft 14. Figure 4 As shown, a two-way dividing slit I 23, one above the other, is provided laterally at the end of the first connector 2 to cut off the shaft hole I I21. The portion between the two dividing slits I 23 is the clamping part 22, which is divided into two clamping arms 25 by the dividing slit I I24 at the end. Between the two clamping arms 25 is a clamping hole 26 with a reduced diameter. During the process of inserting the mounting shaft 14 into the shaft hole I I21, the clamping hole 26 is compressed and expanded. When the annular groove 15 reaches the clamping hole 26, the clamping hole 26 automatically clamps the annular groove 15. Therefore, the mounting shaft 14 can be positioned without additional operation, and the clamping part 22 of this structure does not affect the installation and removal of the mounting shaft 14.

[0027] In the adjustable tightness strap assembly provided in this embodiment, the strap body composed of the apron and the inner lining layer 8 has deformation properties in the length direction, and the first connector 2 and the second connector 3 are connected by a pull cord 4. Since the length of the pull cord can be directly adjusted by the pull cord retractor 7, the actual length of the strap part can be adjusted by the pull cord retractor 7. For the strap assembly in the wearing state, the user does not need to untie it, but can adjust the tightness of the binding simply by adjusting the pull cord retractor 7. In addition, the user can adjust the upper and lower pull cord retractors 7 separately, thereby independently adjusting the tightness of the upper and lower parts of the strap, and the user can perceive the adjustment status in real time. Therefore, the strap assembly can achieve the optimal binding state.

[0028] Based on the strap assembly with the above structure, this utility model also provides an exoskeleton device, such as... Figure 5As shown, the exoskeleton device includes an exoskeleton 100, with a strap assembly 101 disposed on the side of the exoskeleton that conforms to the human body. The strap assembly 101 possesses the aforementioned features of a strap assembly that facilitates adjustment of tightness. Additionally, the strap assembly 101 includes a fixing seat 9 fixedly mounted on the exoskeleton 100, such as... Figure 6 As shown, a hinge seat 16 is provided on the back of the mounting part 1. The hinge seat 16 is hinged to the fixed base 9 via a horizontally arranged hinge shaft 17. In this embodiment, the exoskeleton 100 is a lower limb exoskeleton, and the strap assembly 101 is bound from the side of the leg. The hinge shaft 17 extends along the front-back direction of the human body. Figure 7 As can be seen, in the installed state, there is a space for movement between the installation part 1 and the exoskeleton 100, and a limiting block 102 is set in the space for movement. The limiting block 102 has mounting holes 103 perpendicular to the exoskeleton at both ends. The installation part 1 is provided with limiting bolt holes 18 corresponding to the mounting holes 103, and is equipped with limiting bolts 19. The limiting block 102 is fixed by the limiting bolts 19, which can restrict the installation part 1 from deflecting around the hinge axis 17. That is, the strap assembly 101 is rigidly installed at this time. When the limiting block 102 is removed, the installation part 1 can deflect under the constraint of the hinge axis 17. Therefore, the strap assembly 10 can flexibly adapt to the movement of the human body during use. When worn, if the user feels that the tightness of the strap assembly 101 is not suitable, the strap assembly 101 can be adjusted by rotating the cable retractor 7. Compared with the strap adjustment structure of existing similar exoskeletons, the strap assembly 101 in this exoskeleton does not need to be untied, and the user can sense the binding force in real time, enabling precise and quick adjustment of the strap assembly, thus making the user wear the exoskeleton more comfortably.
