[0001] The utility model relates to the technical field of power-assisting devices, in particular to a power-assisting exoskeleton device. Background Art

[0002] An exoskeleton is a mechanical device that can be worn on the outside of the human body. It is a human-machine collaborative device that enhances the wearer's capabilities through high-demand ergonomic design, power system design and material selection.

[0003] In the military field, exoskeletons are mainly used to improve the individual combat capabilities of soldiers. Specifically, exoskeletons can enhance the strength and endurance of soldiers, allowing them to carry heavy weapons and equipment more easily and maintain a high-intensity combat state for a longer period of time on the battlefield.

[0004] In the civilian field, exoskeletons are also widely used. In the industrial field, exoskeletons can help workers complete heavy or high-risk tasks, such as assembly, logistics, welding, painting, etc. By reducing the physical load and physical exertion of workers, exoskeletons can improve work efficiency and reduce the incidence of occupational diseases.

[0005] Existing assisted exoskeleton devices focus more on providing assistance for activities such as walking, running or carrying heavy objects, but there are no auxiliary mechanisms specially designed for the standing process. As a result, the wearer needs to rely on his or her own strength to complete the process from bending the legs to standing, which increases fatigue. Utility Model Content

[0006] The utility model aims at the technical problems existing in the prior art and provides a power-assisted exoskeleton device to solve the problem that bending the legs easily increases the force on the legs.

[0007] The utility model solves the above-mentioned technical problems with a technical solution as follows: a power-assisted exoskeleton device, comprising a waist support, wherein a waist accommodating cavity with a wearing opening reserved on the front side is formed in the waist support; the wearing opening of the waist accommodating cavity is provided with a waist fixing belt; two groups of thigh supports are movably connected along the outer sides of the wearer's legs below the waist support, and thigh straps are provided on the thigh supports; calf supports and foot supports movably connected to each other are provided in sequence below the thigh supports; calf straps and foot straps are provided on the calf supports and foot supports, respectively; a retractable support rod is also provided between the thigh supports and the calf supports; a back support is also provided above the waist support, and a chest and back fixing belt is provided on the back support.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the back support can be deflected relative to the waist support along the movement direction of the wearer's waist.

[0010] Furthermore, the back of the waist support is also equipped with a force-bearing bracket extending to the rear of the back support, and a limiting seat is installed on the force-bearing bracket.

[0011] Furthermore, elastic bridge frames are provided on both sides of the limit seat, and a plurality of pull ropes are provided between the elastic bridge frames and the back support.

[0012] Furthermore, the elastic bridge frame includes two groups of triangular elastic plates arranged at intervals, and connecting blocks are arranged at the outer ends of the two groups of triangular elastic plates.

[0013] Furthermore, a drawstring fixing hole is provided on the triangular elastic plate near the back support side; and a plurality of drawstring fixing rings corresponding to the drawstring fixing holes are also provided on the back support.

[0014] Furthermore, a telescopic rod connected to the triangular elastic plate is arranged on the limit seat, and a tension spring connected to the triangular elastic plate and the limit seat is arranged on the telescopic rod.

[0015] Moreover, the power-assisted exoskeleton device provided by the present invention has at least the following beneficial effects compared with the prior art:

[0016] 1. Through the design of waist straps, thigh straps, calf straps and foot straps, the device can fit the user's body closely, ensuring that it provides support without affecting the user's comfort. At the same time, these straps are adjustable and can be adjusted according to the body shape and size of different users, enhancing the adaptability of the device.

[0017] 2. The thigh support, calf support and foot support provide support for the user's lower body, especially when walking, standing or doing other activities. The retractable support rod can be extended and retracted according to the user's movements, providing power assistance for the user's leg movements, helping the user to walk, lift legs and other movements more easily, thereby reducing the user's physical burden.

[0018] 3. Through the design of elastically deformable bridge and pull rope, the device can provide appropriate support and cushioning when the user bends, turns, etc. The triangular elastic plate will deform elastically when subjected to external force, and transmit the force to the back support through the pull rope to provide support for the user. At the same time, the design of the tension spring can provide a "rebound" or "boost" effect for the user after the action is completed, helping the user to complete the action more easily and improving the dynamic stability of the device.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] like Figure 1 and Figure 2 As shown, the power-assisted exoskeleton device of the present practical design comprises a waist support 1, wherein the waist support 1 has a waist accommodating cavity with a reserved wearing opening on the front side; the wearing opening of the waist accommodating cavity is provided with a waist fixing belt 2; two groups of thigh supports 3 are movably connected along the outer sides of the wearer's legs below the waist support 1, and thigh straps 3.1 are provided on the thigh supports 3; a calf support 4 and a foot support 5 movably connected to each other are provided in sequence below the thigh supports 3; the calf support 4 and the foot support 5 are respectively provided with a calf strap 4.1 and a foot strap 5.1; a retractable support rod 6 is also provided between the thigh support 3 and the calf support 4; a back support 7 is also provided above the waist support 1, and a chest and back fixing belt 7.1 is provided on the back support 7.

[0026] In this embodiment, the user first puts the waist into the reserved wearing opening on the front side of the waist support 1, and fixes the waist support 1 to the user's waist through the waist fixing belt 2 to ensure that the waist support 1 is stable and fits the user's waist.

[0027] On the thigh support 3, the support is fixed to the outer side of the user's thigh by means of a thigh strap 3.1 to ensure the stability and fit of the support.

[0028] Similarly, the calf support 4 is fixed to the user's calf by a calf strap 4.1, and the foot support 5 is fixed to the user's foot by a foot strap 5.1.

[0029] The lumbar support 1 and the back support 7 together provide support for the upper body of the user. In particular, the back support 7 provides support for the back of the user through the chest and back fixing belt 7.1, thereby reducing the burden on the back.

[0030] The thigh support 3, calf support 4 and foot support 5 provide support for the user's lower body and help the user to distribute the weight of the legs, especially when walking, standing or performing other activities. The retractable support rod 6 is arranged between the thigh support 3 and the calf support 4. It can be retracted and extended according to the user's movements, providing power assistance for the user's leg movements, and helping the user to walk, lift legs and other movements more easily.

[0031] The telescopic support rod 6 can use a gas spring, an air spring or a hydraulic rod as its core mechanism.

[0032] As an embodiment, the back support 7 can be deflected relative to the waist support 1 along the direction of the wearer's waist movement. The back support 7 can be deflected relative to the waist support 1 along the direction of the wearer's waist movement. This design allows the back support to move naturally with the waist when the user bends, turns, etc., thereby improving the comfort and flexibility of wearing.

[0033] Specifically, the back of the waist support 1 is also equipped with a force-bearing bracket 8 extending to the rear of the back support 7, and a limit seat 9 is installed on the force-bearing bracket 8. The force-bearing bracket 8 is used to support and transmit the force on the back support 7, and the limit seat 9 is used to limit the movement of the back support 7 within a certain range to avoid excessive deflection or rotation, thereby ensuring the stability and safety of the device.

[0034] In addition, elastic bridge frames 10 are provided on both sides of the limiting seat 9 , and a plurality of pull ropes 11 are provided between the elastic bridge frames 10 and the back support 7 .

[0035] The elastic bridge 10 comprises two sets of triangular elastic plates 10.1 which are arranged at intervals, and connecting blocks 10.2 are arranged at the outer ends of the two sets of triangular elastic plates 10.1.

[0036] When the back support 7 is subjected to external force, such as when the user bends or turns around, the triangular elastic plate 10.1 will undergo elastic deformation, and the force will be transmitted to the back support 7 through the pull rope 11, thereby providing appropriate support and cushioning for the user.

[0037] As an implementation mode, a drawstring fixing hole 10.3 is provided on the triangular elastic plate 10.1 near the back support 7; and a plurality of drawstring fixing rings 7.2 corresponding to the drawstring fixing holes 10.3 are also provided on the back support 7. The drawstring 11 can be fixed and adjusted, so as to adjust the size and distribution of the supporting force according to the user's personalized needs such as body shape and movement habits, thereby improving the comfort and adaptability of wearing.

[0038] As an implementation mode, the limit seat 9 is provided with a telescopic rod 10.4 connected to the triangular elastic plate 10.1, and the telescopic rod 10.4 is provided with a tension spring 10.5 connected to the triangular elastic plate 10.1 and the limit seat 9 respectively.

[0039] When the user bends or turns around, the back support 7 will deflect relative to the waist support 1. At this time, the triangular elastic plate 10.1 will be deformed by the traction force of the back support 7.

[0040] Since the triangular elastic plate 10.1 is connected to the telescopic rod 10.4, the telescopic rod 10.4 will be extended and retracted accordingly.

[0041] The extension and retraction of the telescopic rod 10.4 will further stretch or compress the tension spring 10.5. The elastic force of the tension spring 10.5 will provide a "rebound" or "boost" effect for the user, helping the user to complete the action more easily.
