Description

Technical Field

[0001] This application relates to the field of exoskeleton device technology, and more particularly to a strap assembly, exoskeleton device and wearable device. Background Technology

[0002] An exoskeleton is a mechanical device worn on the human body that mimics the structure of the human skeleton. It assists in limb movement or provides rehabilitation through mechanical joints. In some technologies, straps are used to secure the exoskeleton to the hip, knee, or ankle joints. However, since fastening and unlocking the straps requires both hands, it cannot be done independently with one hand, resulting in a lengthy wearing experience and reduced comfort. Summary of the Invention

[0003] This application provides a strap component, an exoskeleton device, and a wearable device to solve the technical problems of using straps to fix the exoskeleton device, making it difficult to operate with one hand and taking a long time to put on.

[0004] In a first aspect, embodiments of this application provide a strap assembly, including a support plate, a snap ring, a fastener body, a strap, and a first magnet. The strap is connected to the fastener body, and the fastener body has a hook portion on the side facing the support plate. The first end of the snap ring is movably connected to the support plate, and the second end of the snap ring is provided with a magnetic attraction portion. The first magnet is disposed on the fastener body and is used to attract the magnetic attraction part when the fastener body is close to the snap ring, so that the hook part hooks the magnetic attraction part.

[0005] In this embodiment, the hook portion has a slot. When the fastener body approaches the snap ring, the magnetic part is at least partially embedded in the slot and fits against the slot.

[0006] In this embodiment, the magnetic suction part and the snap ring are detachably connected, or the magnetic suction part and the snap ring are integrally formed.

[0007] In this embodiment of the application, the strap assembly further includes a flexible strap, one end of which is fixedly connected to the support plate, and the other end of which is sleeved with the first end of the snap ring.

[0008] In this embodiment of the application, the strap assembly further includes a lifting member, which is connected to one end of the buckle body away from the strap, and the lifting member is used to pull the buckle body.

[0009] In this embodiment of the application, the fastener body has a mounting groove on the side facing away from the support plate, and the first magnet is embedded in the mounting groove; The strap assembly also includes a shielding plate that covers the opening of the mounting groove.

[0010] In this embodiment of the application, the strap assembly further includes a second magnet disposed on the support plate. The second magnet is used to attract the magnetic attraction part when the fastener body is away from the snap ring, so that the snap ring is connected to the support plate.

[0011] In this embodiment of the application, the fastener body is provided with a socket hole, and at least part of the strap passes through the socket hole so that the fastener body can be pulled under the action of external force.

[0012] Secondly, embodiments of this application also provide an exoskeleton device, including the aforementioned strap assembly.

[0013] Thirdly, embodiments of this application also provide a wearable device, including the strap assembly.

[0014] This application provides a strap assembly for use in exoskeleton devices. In the initial state, the buckle body is separated from the locking ring. During wear, the buckle body is driven close to the locking ring, and a first magnet attracts the magnetic part, causing the locking ring to move towards the hook part. The hook part hooks the magnetic part, thus completing the fastening. The strap is connected to the buckle body and can undergo elastic deformation under external force. After releasing the buckle body, the strap exerts an elastic tension on the buckle body, thereby securely binding the exoskeleton device to the limb. When unfastening is required, the buckle body is pulled to disengage the magnetic part from the hook part, releasing the hook part from the locking ring. In this embodiment, the buckle body can be pulled with one hand to quickly achieve the fastening or unfastening operation of the hook part and the locking ring, making the wearing process simple and convenient, reducing wearing time, and improving the wearing experience of the exoskeleton device.

Detailed Implementation

[0018] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] In the description of this application, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc. used in this application to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device and element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] In related technologies, straps are frequently used to wear exoskeleton devices on the human body, and the securing and releasing of these straps is a crucial part of putting on and taking off exoskeleton devices. Existing straps are difficult to operate with one hand, requiring both hands to apply force to fasten or unlock them, limiting their application scenarios. Furthermore, they are prone to loosening after being secured, affecting the stability of the exoskeleton device. In addition, unlocking the straps after securing them is difficult, requiring considerable force and resulting in an uneven unlocking process. like Figures 1 to 4 As shown, this application embodiment provides a strap assembly, including a support plate 10, a snap ring 20, a fastener body 30, a strap 40, and a first magnet 50. The strap 40 is connected to the fastener body 30, and the fastener body 30 has a hook portion 31 on the side facing the support plate 10. The first end of the snap ring 20 is movably connected to the support plate 10, and the second end of the snap ring 20 is provided with a magnetic attraction portion 21. The first magnet 50 is disposed on the fastener body 30 and is used to attract the magnetic attraction portion 21 when the fastener body 30 is close to the snap ring 20, so that the hook portion 31 hooks the magnetic attraction portion 21.

[0021] In this embodiment of the application, the first end and the second end of the snap ring 20 are the opposite ends of the snap ring 20, and the first end of the snap ring 20 is movably connected to the support plate 10, so that the snap ring 20 has a certain degree of freedom relative to the support plate 10.

[0022] Based on the above technical solution, the strap assembly is applied to the exoskeleton device. The support plate 10 serves as the pressure equalizing plate of the exoskeleton device and is a structure that comes into contact with and fits the human limb. Initially, the buckle body 30 is separated from the locking ring 20. When wearing the exoskeleton device, the buckle body 30 is driven closer to the locking ring 20. The first magnet 50 magnetically attracts the magnetic suction part 21, causing the locking ring 20 to move towards the hook part 31. The hook part 31 hooks the magnetic suction part 21, thus completing the fastening with the locking ring 20. The strap 40 is connected to the buckle body 30. The strap 40 can elastically deform under external force. After releasing the buckle body 30, the strap 40 generates an elastic tension on the buckle body 30, forming a binding structure with the support plate 10, thereby securely binding the exoskeleton device to the limb. When unbinding is required, the buckle body 30 is further pulled to disengage the magnetic suction part 21 from the hook part 31, releasing the fastening between the hook part 31 and the locking ring 20.

[0023] In this embodiment, the strap assembly is applied to an exoskeleton device, allowing for quick engagement or disengagement of the hook 31 and the locking ring 20 by pulling the buckle body 30 with one hand. This makes the wearing process simple and convenient, reduces wearing time, and improves the wearing experience of the exoskeleton device.

[0024] In this embodiment, the exoskeleton device is fixed to the hip, knee or ankle joint of the human body by the strap assembly; the support plate 10 can be attached to the thigh, calf, waist, abdomen, shoulder and back and other limb parts, and the pressure equalizing plate is pressed tightly against the human body limb by the tension of the strap 40.

[0025] In some embodiments, the first magnet 50 can be installed inside the fastener body 30, or on the side of the fastener body 30 facing the support plate 10, or on the side of the fastener body 30 away from the support plate 10, as long as it can generate a magnetic attraction effect on the magnetic attraction part 21.

[0026] In some embodiments, the magnetic attraction part 21 may be made of a magnetically conductive material such as iron, cobalt, nickel or ferrite, and the magnetic attraction part 21 may also be a magnetic structure with the opposite magnetism to that of the first magnet 50.

[0027] In some embodiments, such as Figure 2 and Figure 5 As shown, the hook portion 31 has a slot 32. When the fastener body 30 approaches the snap ring 20, the magnetic part 21 is at least partially embedded in the slot 32 and fits against the slot 32.

[0028] Specifically, the slot 32 is adapted to the shape and size of the magnetic suction part 21. When the first magnet 50 attracts the magnetic suction part 21, the magnetic suction part 21 is fully or partially embedded in the slot 32. The slot 32 forms a limiting constraint on the magnetic suction part 21. The tension of the strap 40 makes the magnetic suction part 21 fit tightly against the inner wall of the slot 32 to prevent the magnetic suction part 21 from shifting or moving, thereby improving the connection stability between the locking ring 20 and the fastener body 30 and reducing the risk of the strap assembly loosening. It can be understood that the magnetic suction part 21 is embedded in the slot 32 to form a locking effect, ensuring that the exoskeleton device is bound to the limb joints and will not loosen due to limb flexion, extension, or walking, thus improving the wearing stability and user experience of the exoskeleton device.

[0029] In some embodiments, the magnetic part 21 and the snap ring 20 are detachably connected, or the magnetic part 21 and the snap ring 20 are integrally formed.

[0030] For example, the snap ring 20 is a closed ring structure, and the magnetic part 21 is an iron ring. The iron ring is sleeved or wrapped around the ring structure, so that the magnetic part 21 and the snap ring 20 can form an integral structure.

[0031] For example, the snap ring 20 is a closed plastic ring, and the magnetic part 21 is a part of the metal inside the plastic ring, so that the magnetic part 21 and the snap ring 20 can be formed as an integral structure.

[0032] For example, the snap ring 20 is a plastic ring with an opening, and the magnetic part 21 is a metal part located at the opening. The two ends of the metal part are detachably connected to the two ends of the opening of the plastic ring.

[0033] For example, the snap ring 20 and the magnetic part 21 are made of the same material. The ring structure formed by the snap ring 20 and the magnetic part 21 is made of magnetically conductive material or magnet. The entire snap ring 20 can be attracted by the first magnet 50, thereby enhancing the magnetic attraction stability between the first magnet 50 and the snap ring 20.

[0034] In some embodiments, such as Figure 2 As shown, the fastener body 30 is provided with a socket 34, and at least part of the strap 40 passes through the socket 34 so that the fastener body 30 can be pulled under the action of external force.

[0035] Specifically, such as Figure 6 As shown, when it is necessary to tighten the strap 40, the strap 40 can be pulled in the first direction X. The strap 40 passes through the socket 34 and exerts a pulling force on the buckle body 30, keeping the hook part 31 and the locking ring 20 in a tight fastened state, thereby securely binding the exoskeleton device to the limb. When it is necessary to untie, the strap 40 is released. The strap 40 no longer exerts a pulling force on the buckle body 30, and the hook part 31 and the locking ring 20 can be separated, thereby removing the exoskeleton device from the limb.

[0036] In some embodiments, such as Figures 2 to 6 As shown, the strap assembly also includes a flexible strap 60, one end of which is fixedly connected to the support plate 10, and the other end of which is sleeved with the first end of the snap ring 20.

[0037] Specifically, the flexible strip 60 has the characteristics of being bendable and deformable after stretching. One end of the flexible strip 60 is fixedly connected to the support plate 10, and the other end is sleeved with the snap ring 20, so that the snap ring 20 has a degree of freedom of movement relative to the support plate 10. When the fastener body 30 is pulled close to the snap ring 20 with one hand, the first magnet 50 generates a magnetic attraction effect on the magnetic attraction part 21, causing the snap ring 20 to move toward the hook part 31. The snap ring 20 pulls the flexible strip 60, so that the snap ring 20 can be attracted by the first magnet 50 and hooked by the hook part 31.

[0038] In some embodiments, the flexible strip 60 can be a webbing such as nylon or polyester. One end of the flexible strip 60 can be fixed to the support plate 10 by sewing or injection molding, and the other end is perforated for the card-connecting ring 20 to pass through and connect.

[0039] In some embodiments, such as Figures 1 to 6 As shown, the strap assembly also includes a lifting member 70, which is connected to the end of the buckle body 30 away from the strap 40, and is used to pull the buckle body 30.

[0040] Specifically, based on the connection between the flexible strip 60 and the snap ring 20, one end of the fastener body 30 is connected to the strap 40, and the other end is connected to the lifting member 70, so that the strap 40 and the lifting member 70 are respectively bound to the opposite ends of the fastener body 30. Compared with the method of directly grasping the fastener body 30 for pulling operation, the lifting member 70 provided in this embodiment forms a pulling point, which can increase the hand gripping contact area, avoid the problem of slipping or pinching the fingers when directly gripping the fastener body 30, reduce the difficulty of single-handed pulling operation, and facilitate operation.

[0041] For example, when wearing the garment, the lifting member 70 is held with one hand and pulled, causing the buckle body 30 to move closer to the locking ring 20. The first magnet 50 attracts the magnetic part 21 to complete the fastening, thus quickly completing the wearing process. When disassembling or unlocking, the lifting member 70 can be pulled in the second direction Y or the third direction X. Due to the limited travel of the flexible band 60 and the locking ring 20, the magnetic part 21 can disengage from the edge of the slot 32 of the hook part 31, thereby releasing the magnetic part 21 from the constraint of the hook part 31 and releasing the fastening between the hook part 31 and the locking ring 20.

[0042] In some embodiments, the lifting member 70 may be a handle with a certain degree of flexibility.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the fastener body 30 has a mounting groove 33 on the side opposite to the support plate 10, and the first magnet 50 is embedded in the mounting groove 33; the strap assembly also includes a shielding plate 80, which covers the opening of the mounting groove 33.

[0044] Specifically, the side of the fastener body 30 facing the support plate 10 is considered the front side of the fastener body 30, and the side of the fastener body 30 facing away from the support plate 10 is considered the back side of the fastener body 30. In this embodiment, a mounting groove 33 is formed on the back side of the fastener body 30. The mounting groove 33 is adapted to the shape and size of the first magnet 50, and the first magnet 50 is embedded in the mounting groove 33, thereby assembling the first magnet 50 inside the fastener body 30. Then, the opening of the mounting groove 33 is covered by a shielding plate 80. The shielding plate 80 can better close the magnetic circuit, reduce the leakage of magnetic flux to the outside of the fastener body 30, and thus enhance the attraction force of the first magnet 50 to the magnetic attraction part 21.

[0045] Furthermore, the shielding plate 80 can reduce the attraction of the first magnet 50 to external metal debris, metal parts, and other foreign objects, preventing these objects from adhering to the surface of the fastener body 30. For example, it prevents the attraction of metal items such as keys and coins, which could cause interference when worn. Moreover, the shielding plate 80 covers the outside of the first magnet 50, providing protection and preventing it from falling off or corroding.

[0046] In some embodiments, such as Figure 3 As shown, the strap assembly also includes a second magnet 90, which is disposed on the support plate 10. The second magnet 90 is used to attract the magnetic part 21 when the fastener body 30 is away from the snap ring 20, so that the snap ring 20 is connected to the support plate 10.

[0047] Specifically, when the fastener body 30 is away from the snap ring 20 and the strap assembly is in an unlocked, loose state, the second magnet 90 on the support plate 10 can attract the magnetic suction part 21, which has a restraining effect on the snap ring 20, so that the snap ring 20 is close to and gathered on the surface of the support plate 10, preventing the snap ring 20 from shaking randomly when the strap assembly is not locked.

[0048] In some embodiments, the second magnet 90 may be fitted inside the support plate 10 or on the surface of the support plate 10.

[0049] Secondly, embodiments of this application also provide an exoskeleton device, including a strap assembly.

[0050] Specifically, when wearing the exoskeleton device, the buckle body 30 is driven close to the locking ring 20. The first magnet 50 magnetically attracts the magnetic suction part 21, causing the locking ring 20 to move towards the hook part 31. The hook part 31 hooks the magnetic suction part 21, thus completing the fastening with the locking ring 20. The strap 40 is connected to the buckle body 30. The strap 40 can elastically deform under external force. After releasing the buckle body 30, the strap 40 generates an elastic tension on the buckle body 30, forming a binding structure with the support plate 10, thereby firmly binding the exoskeleton device to the limb. When it is necessary to unbind, the buckle body 30 is further pulled to disengage the magnetic suction part 21 from the constraint of the hook part 31, releasing the fastening between the hook part 31 and the locking ring 20. In this embodiment, the strap assembly can be operated with one hand, quickly realizing the wearing of the exoskeleton device. The wearing process is simple and convenient, reducing the wearing time and improving the wearing experience of the exoskeleton device.

[0051] In practical applications, exoskeleton devices can be categorized by usage scenario into industrial load-bearing exoskeletons, medical rehabilitation exoskeletons, consumer-grade exoskeletons, and special military exoskeletons. They can also be classified by drive method into passive elastic assistive exoskeletons and active motor-driven exoskeletons. Furthermore, they can be classified by the limbs on which they are worn, such as lower limb exoskeletons, upper limb exoskeletons, and full-body exoskeletons. Industrial exoskeletons are primarily used in factory handling and construction to reduce the burden and strain on the human body. Rehabilitation exoskeletons are mainly used for gait and joint rehabilitation training for patients with limb movement disorders. Consumer-grade exoskeletons assist the general population in daily walking activities such as climbing mountains and going up and down stairs. Military exoskeletons enhance the load-bearing, movement, and combat capabilities of individual soldiers. Passive exoskeletons rely on elastic components for assistance, are lightweight, and have no power source. Active exoskeletons utilize motors and hydraulic mechanisms to output active assist torque. Lower limb exoskeletons provide walking support for the hip, knee, and ankle joints, upper limb exoskeletons assist in lifting heavy objects, and full-body exoskeletons simultaneously cover both the upper and lower limbs to achieve comprehensive load-bearing assistance.

[0052] Thirdly, embodiments of this application also provide a wearable device, including a strap assembly.

[0053] Specifically, by applying the strap component to wearable devices, the strap component can be operated with one hand, enabling quick and easy device wearing. The wearing process is simple and convenient, reducing the time required for wearing and improving the user experience.

[0054] In some embodiments, wearable devices may be knee pads, waist supports, belts, back straps, ankle orthotics, helmets, vests, etc., and the specific type of wearable device is not limited here.
