[0002] In the field of lower limb rehabilitation, assistive devices play a crucial role in promoting patient recovery and improving treatment outcomes. However, existing lower limb rehabilitation assistive devices lack lateral adjustment, hindering their adaptability to users of different body types. Due to individual differences in body shape, fixed-size assistive devices struggle to meet the needs of all users. [Utility Model Content]
[0003] To address the problem that existing lower limb rehabilitation assistive devices cannot adapt to users of different body types, this application provides a lateral adjustment component for a lower limb rehabilitation assistive device.
[0004] This application is achieved through the following technical solution:
[0005] A lateral adjustment component of a lower limb rehabilitation assistive device includes a first arm assembly, a second arm assembly disposed opposite to the first arm assembly and cooperating to form an activity space, and an adjustment mechanism for adjusting the distance between the first arm assembly and the second arm assembly. The adjustment mechanism includes a wheel, a first toothed rail disposed on the first arm assembly, and a second toothed rail disposed on the second arm assembly. The wheel has teeth that mesh with the first toothed rail and the second toothed rail respectively.
[0006] As described above, the lateral adjustment assembly of a lower limb rehabilitation assistive device includes a first arm assembly comprising a first hollow curved tube, a first handle disposed on the first hollow curved tube, and a first handrail pad disposed on the first hollow curved tube. The first handle protrudes outward from the first hollow curved tube and extends upward, while the first handrail pad extends outward in a horizontal direction relative to the first hollow curved tube. The second arm assembly comprises a second hollow curved tube, a second handle disposed on the second hollow curved tube, and a second handrail pad disposed on the second hollow curved tube. The second handle protrudes outward from the second hollow curved tube and extends upward, while the second handrail pad extends outward in a horizontal direction relative to the second hollow curved tube.
[0007] As described above, in the lateral adjustment component of a lower limb rehabilitation assistive device, the first toothed rail is located on the upper side of the inner wall of the first hollow bend, and the second toothed rail is located on the lower side of the inner wall of the second hollow bend; or the first toothed rail is located on the lower side of the inner wall of the first hollow bend, and the second toothed rail is located on the upper side of the inner wall of the second hollow bend.
[0008] The lateral adjustment component of the lower limb rehabilitation assistive device described above further includes a protective housing. The first hollow bend, the second hollow bend, and the wheel are partially nested within the protective housing. When the wheel rotates clockwise or counterclockwise, it causes the first hollow bend and the second hollow bend to extend or retract into the protective housing.
[0009] The lateral adjustment component of the lower limb rehabilitation assistive device described above further includes a handrail positioning block disposed on the first hollow bend and / or the second hollow bend and located inside the protective box.

[0010] The lateral adjustment component of the lower limb rehabilitation assistive device described above also includes fasteners, and the protective housing is provided with a connection hole through which the fasteners pass to abut against the first hollow bend or the second hollow bend.
[0011] The lateral adjustment component of the lower limb rehabilitation assistive device described above further includes a mounting base and a lifting component disposed within the mounting base and connected to the protective housing. The lifting component drives the protective housing to move up and down relative to the mounting base, thereby driving the first arm assembly and the second arm assembly to move up and down.
[0012] The lateral adjustment component of the lower limb rehabilitation assistive device described above has a handle on the wheel.
[0013] Compared with the prior art, this application has the following advantages:
[0014] The lateral adjustment component of the lower limb rehabilitation assistive device of this application, by rotating the wheel in the forward or reverse direction, causes the first and second toothed rails to drive the first and second arm components closer or further apart under the action of the teeth on the wheel, so as to adjust the size of the activity space between the first and second arm components, making the rehabilitation assistive device more in line with the user's body size, thereby improving the applicability and comfort of the assistive device.

Detailed Implementation Methods
[0021] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0022] Please see Figures 1 to 5 A lateral adjustment component of a lower limb rehabilitation assistive device includes a first arm assembly 1, a second arm assembly 3 disposed opposite to the first arm assembly 1 and forming an activity space 2, and an adjustment mechanism 4 for adjusting the distance between the first arm assembly 1 and the second arm assembly 3. The adjustment mechanism 4 includes a wheel 41, a first toothed rail 42 disposed on the first arm assembly 1, and a second toothed rail 43 disposed on the second arm assembly 3. The wheel 41 is provided with teeth 44 that mesh with the first toothed rail 42 and the second toothed rail 43 respectively.
[0023] The lateral adjustment component of the lower limb rehabilitation assistive device of this application, by rotating the wheel in the forward or reverse direction, causes the first and second toothed rails to drive the first and second arm components closer or further apart under the action of the teeth on the wheel, so as to adjust the size of the activity space between the first and second arm components, making the rehabilitation assistive device more in line with the user's body size, thereby improving the applicability and comfort of the assistive device.
[0024] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first arm assembly 1 includes a first hollow bend tube 11, a first handle 12 disposed on the first hollow bend tube 11, and a first handrail pad 13 disposed on the first hollow bend tube 11. The first handle 12 protrudes outward from the first hollow bend tube 11 and extends upward, and the first handrail pad 13 extends outward in a horizontal direction relative to the first hollow bend tube 11. The second arm assembly 3 includes a second hollow bend tube 31, a second handle 32 disposed on the second hollow bend tube 31, and a second handrail pad 33 disposed on the second hollow bend tube 31. The second handle 32 protrudes outward from the second hollow bend tube 31 and extends upward, and the second handrail pad 33 extends outward in a horizontal direction relative to the second hollow bend tube 31.
[0025] In this embodiment, by installing handles and armrest pads on the hollow curved tube, the device provides the support and grip strength needed by the user during rehabilitation, which helps stabilize the body and promotes lower limb rehabilitation training. At the same time, this design can accommodate users of different body types and rehabilitation needs, improving the versatility and applicability of the device.
[0026] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first toothed rail 42 is located on the upper side of the inner wall of the first hollow bend 11, and the second toothed rail 43 is located on the lower side of the inner wall of the second hollow bend 31; or the first toothed rail 42 is located on the lower side of the inner wall of the first hollow bend 11, and the second toothed rail 43 is located on the upper side of the inner wall of the second hollow bend 31.
[0027] In this embodiment, by setting the first toothed rail on the upper side of the inner wall of the first hollow bend and the second toothed rail on the lower side of the inner wall of the second hollow bend, or by setting the first toothed rail on the lower side of the inner wall of the first hollow bend and the second toothed rail on the upper side of the inner wall of the second hollow bend, the correct meshing of the gear teeth on the wheel with the first and second toothed rails can be ensured, thereby achieving precise adjustment of the gap between the first arm assembly and the second arm assembly. This design can improve the reliability and stability of the adjustment mechanism.
[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a protective housing 5, in which the first hollow bend 11, the second hollow bend 31, and the wheel 41 are partially nested within the protective housing 5. When the wheel 41 rotates clockwise or counterclockwise, it causes the first hollow bend 11 and the second hollow bend 31 to extend or retract into the protective housing 5.
[0029] In this embodiment, by partially nesting the first hollow bend, the second hollow bend, and the wheel within the protective housing, the linked components can be effectively protected, preventing external impacts or damage during use. Simultaneously, the protective housing provides a neat appearance, enhancing the overall aesthetics of the device. Furthermore, when the wheel rotates clockwise or counterclockwise, it can extend or retract the first and second hollow bends within the protective housing, thereby adjusting the spacing between the arm components. The protective housing can be made of different shapes or materials to meet specific usage requirements. For example, waterproof materials can be used to protect the internal components from humid environments, or transparent materials can be used to facilitate observation of the internal components' operational status.
[0030] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a handrail positioning block 6 disposed on the first hollow bend 11 and / or the second hollow bend 31 and located inside the protective housing 5. The handrail positioning block 6 is used to abut against the inner wall of the protective housing 5 to limit the movement distance of the first hollow bend 11 and the second hollow bend 31.
[0031] In this embodiment, by setting handrail positioning blocks on the first hollow bend and / or the second hollow bend, and positioning them within the protective housing and abutting against the inner wall of the protective housing, the movement distance of the first and second hollow bends can be limited, thereby ensuring that the adjustment range of the spacing between the arm assemblies is within a safe and reasonable range. This improves the stability and reliability of the device and avoids over-adjustment. The handrail positioning blocks can be made of elastic material to provide a certain degree of cushioning.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a fastener 7, wherein the protective housing 5 is provided with a connection hole 8 through which the fastener 7 passes to abut against the first hollow bend 11 or the second hollow bend 31.
[0033] In this embodiment, by providing connection holes on the protective housing and using fasteners to pass through the connection holes and abut against the first hollow bend or the second hollow bend, the arm assembly can be fixed and locked to prevent accidental movement or loosening during use.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a mounting base 9 and a lifting assembly 10 disposed within the mounting base 9 and connected to the protective housing 5. The lifting assembly 10 drives the protective housing 5 to move up and down relative to the mounting base 9, thereby driving the first arm assembly 1 and the second arm assembly 3 to move up and down.
[0035] In this embodiment, by installing a lifting assembly within the mounting base and connecting it to the protective housing, the protective housing and its internal first and second arm assemblies can move vertically. This design can accommodate users of different heights or with varying rehabilitation needs, improving the device's versatility and applicability. The lifting assembly can employ different types or structures to meet specific usage requirements. For example, it can utilize linear drive devices such as hydraulic cylinders or electric push rods, or mechanical transmission devices such as rack and pinion or lead screws.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the wheel 41 is provided with a handle 14.
[0037] In this embodiment, by providing a handle on the wheel, the user can easily rotate the wheel manually, thereby adjusting the distance between the first arm assembly and the second arm assembly. The handle design provides better grip and ease of operation, making the adjustment process easier and more accurate.
[0038] The working principle of this embodiment is as follows:
[0039] The lateral adjustment component of the lower limb rehabilitation assistive device of this application, by rotating the wheel in the forward or reverse direction, causes the first and second toothed rails to drive the first and second arm components closer or further apart under the action of the teeth on the wheel, so as to adjust the size of the activity space between the first and second arm components, making the rehabilitation assistive device more in line with the user's body size, thereby improving the applicability and comfort of the assistive device.
[0040] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
