Description

[Technical Field]

[0001] This application belongs to the field of medical device technology, specifically relating to a lower limb rehabilitation assistive device that is easy to transport. [Background Technology]

[0002] Lower limb rehabilitation assistive devices are primarily used to assist patients with lower limb dysfunction in rehabilitation training. By simulating the biomechanical patterns of normal walking, they assist patients in gait training to restore or improve their walking ability. However, because lower limb rehabilitation assistive devices need to integrate multiple sensors, actuators, and complex mechanical structures to achieve precise gait control and force assistance, they often require a large space to accommodate these components. This results in high logistical costs and time when transferring the equipment between hospitals, rehabilitation centers, and other locations. The devices are often large and structurally complex, causing numerous inconveniences in transportation, transfer, and storage. Moreover, the deployment and movement of large equipment in emergency situations are difficult, which is particularly disadvantageous in medical rescue scenarios requiring rapid response. [Utility Model Content]

[0007] As described above, in a lower limb rehabilitation assistive device that facilitates transport, when the folding locking screw presses against the right handrail tube and the adjusting rod, it keeps the left handrail lifting assembly and the right handrail lifting assembly in position; when the folding locking screw releases the right handrail tube and the adjusting rod, the right handrail tube drives the folding locking screw to move left and right along the slide groove, thereby adjusting the interval distance between the left handrail lifting assembly and the right handrail lifting assembly.

[0008] As described above, a lower limb rehabilitation assistive device that is easy to transport includes a movable component comprising pulley mechanisms located at the bottom ends of the left handrail lifting component and the right handrail lifting component, respectively. The pulley mechanism includes a pulley support rod and pulleys located at both ends of the pulley support rod.

[0009] As described above, in a lower limb rehabilitation assistive device that facilitates transport, the hinge points of the left handrail lifting assembly and the right handrail lifting assembly with the pulley support rod are located in the middle of the pulley support rod.

[0010] As described above, in a lower limb rehabilitation assistive device that facilitates transport, the hinge points of the left handrail lifting assembly and the right handrail lifting assembly with the pulley support rod are located at one end of the pulley support rod.

[0011] The lower limb rehabilitation assistive device described above, which is easy to transport, includes two disassembly and assembly mechanisms that are arranged vertically at intervals along the left and right handrail lifting components.

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 lower limb rehabilitation assistive device that is easy to transport includes a left handrail lifting assembly 1, a right handrail lifting assembly 2, a disassembly and assembly mechanism 3 for connecting the left handrail lifting assembly 1 and the right handrail lifting assembly 2 into one unit, and two movable components 4 respectively located at the bottom of the left handrail lifting assembly 1 and the right handrail lifting assembly 2.

[0023] This application discloses a lower limb rehabilitation assistive device that is easy to transport. By designing the device as a detachable structure, including a left armrest lifting assembly, a right armrest lifting assembly, a disassembly and assembly mechanism, and a movable component, the device achieves convenience during transportation and storage. The disassembly and assembly mechanism allows for rapid assembly and disassembly, improving its flexibility of use. Furthermore, the movable component enhances the flexibility and mobility of the device after disassembly, enabling rapid deployment and movement in emergency situations, meeting the rapid response needs in medical rescue scenarios.

[0024] Furthermore, as a preferred embodiment of this solution and not a limitation, the disassembly and assembly mechanism 3 includes a left handrail tube 31 connected to the left handrail lifting assembly 1, a right handrail tube 32 connected to the right handrail lifting assembly 2 and disposed opposite to the left handrail tube 31, and adjusting rods 33 respectively embedded in the left handrail tube 31 and the right handrail tube 32. The adjusting rods 33 are provided with a first connecting hole 331 and a sliding groove 332. The left handrail tube 31 is provided with a second connecting hole 311, and the right handrail tube 32 is provided with a positioning hole 321. Fasteners pass through the second connecting hole 311 and the first connecting hole 331 to connect the left handrail lifting assembly 1 and the right handrail lifting assembly 2. Folding locking screws 34 pass through the positioning hole 321 and the sliding groove 332 and are used to adjust the interval distance between the left handrail lifting assembly 1 and the right handrail lifting assembly 2.

[0025] In this embodiment, the relative arrangement of the left and right handrail tubes and the embedding of the adjusting rod facilitate the convenient connection and separation of the left and right handrail lifting components, thereby simplifying the transportation and storage of the device. The first connecting hole and groove on the adjusting rod, in conjunction with the second connecting hole on the left handrail tube and the positioning hole on the right handrail tube, allow for the separate connection and spacing adjustment of the fasteners and folding locking screws. This structure not only secures the connection between components but also allows for flexible adjustment of the component spacing as needed to accommodate patients of different body types. Furthermore, this design reduces the complexity of the device, making it easier to operate and maintain.

[0026] Furthermore, as a preferred embodiment of this solution and not a limitation, when the folding locking screw 34 presses against the right handrail tube 32 and the adjusting rod 33, it keeps the left handrail lifting assembly 1 and the right handrail lifting assembly 2 in position; when the folding locking screw 34 releases the right handrail tube 32 and the adjusting rod 33, the right handrail tube 32 drives the folding locking screw 34 to move left and right along the slide groove 332, so as to adjust the interval distance between the left handrail lifting assembly 1 and the right handrail lifting assembly 2.

[0027] In this embodiment, the precise adjustment and stable positioning of the gap between the left and right armrest lifting components are achieved through the interaction of the folding locking screw and the sliding groove. When the folding locking screw presses against the right armrest tube and the adjusting rod, the two components are tightly fixed, ensuring stability and safety during use. When the folding locking screw releases pressure, the right armrest tube can move the folding locking screw left and right along the sliding groove, thereby conveniently adjusting the gap between the two components to accommodate patients of different body types. This structure not only improves the adaptability and comfort of the device but also simplifies the operation process, making equipment adjustment more efficient.

[0028] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the movable component 4 includes a pulley mechanism 41 located at both ends of the bottom of the left handrail lifting component 1 and the right handrail lifting component 2, respectively. The pulley mechanism 41 includes a pulley support rod 411 and pulleys 412 located at both ends of the pulley support rod 411.

[0029] In this embodiment, by incorporating pulley mechanisms at both ends of the bottom of the left and right handrail lifting components, the mobility and convenience of the device are significantly improved. The pulley support rods in the pulley mechanisms connect the pulleys at both ends, ensuring that after disassembly, both the left and right handrail lifting components, equipped with four pulleys, can be placed on a flat surface and moved smoothly, reducing frictional resistance and allowing for easy positional adjustments in hospitals, rehabilitation centers, and other similar locations. This design not only reduces the workload of caregivers but also improves the efficiency of the equipment, enabling the lower limb rehabilitation assistive device to respond more quickly to patients' needs.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the hinge points of the left handrail lifting assembly 1 and the right handrail lifting assembly 2 with the pulley support rod 411 are located in the middle of the pulley support rod 411.

[0031] In this embodiment, the mechanical balance and stability of the device are optimized. The central hinge point evenly distributes the weight of the components on both sides, ensuring that the pulley support rod remains horizontal during movement and reducing the risk of tilting or tipping due to uneven force. This structural design not only improves the stability of the device during movement but also enhances its stability during static use, providing patients with safer and more reliable rehabilitation training support.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the hinge points of the left handrail lifting assembly 1 and the right handrail lifting assembly 2 with the pulley support rod 411 are located at one end of the pulley support rod 411.

[0033] In this embodiment, the hinge points of the left and right handrail lifting components and the pulley support rod are set at one end of the pulley support rod, which provides greater flexibility so that the two handrail lifting components can swing or adjust at a greater angle relative to the pulley support rod when moving.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, it includes two disassembly and assembly mechanisms 3 arranged vertically at intervals along the left handrail lifting assembly 1 and the right handrail lifting assembly 2.

[0035] In this embodiment, by adding a disassembly and assembly mechanism, not only is the connection of the components in the height direction strengthened, but an additional support point is also provided to prevent loosening or imbalance that may occur due to a single-point connection. This double-safety structural design ensures the stability of the device under various operating conditions.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a limiting block 5. The left handrail lifting assembly 1 and the right handrail lifting assembly 2 are respectively provided with mounting grooves 11 for the left handrail tube 31 and the right handrail tube 32 to be embedded. The limiting block 5 is connected to the mounting grooves 11 to fix the left handrail tube 31 and the right handrail tube 32 on the left handrail lifting assembly 1 and the right handrail lifting assembly 2 respectively.

[0037] In this embodiment, by setting mounting slots on the left and right handrail lifting components and using limiting blocks to fix the left and right handrail tubes to the corresponding components respectively, a stable connection and disassembly between the disassembly mechanism and the handrail lifting components is achieved. This further reduces the overall space occupied by the device, simplifies the assembly and disassembly process, and improves the ease of operation.

[0038] The working principle of this embodiment is as follows:

[0039] This application discloses a lower limb rehabilitation assistive device that is easy to transport. By designing the device as a detachable structure, including a left armrest lifting assembly, a right armrest lifting assembly, a disassembly and assembly mechanism, and a movable component, the device achieves convenience during transportation and storage. The disassembly and assembly mechanism allows for rapid assembly and disassembly, improving its flexibility of use. Furthermore, the movable component enhances the flexibility and mobility of the device after disassembly, enabling rapid deployment and movement in emergency situations, meeting the rapid response needs in medical rescue scenarios.
