Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, and more specifically, to an electric lower limb rehabilitation training device. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Lower limb training devices are rehabilitation equipment specifically designed to restore lower limb strength, mobility, and coordination. They are commonly used for patients recovering from surgery, those with nerve damage, or those experiencing muscle atrophy. Through passive or active training modes, they help improve joint range of motion, strengthen muscles, and promote the reconstruction of motor function. They are important auxiliary tools in rehabilitation therapy. For postoperative patients, progressive training helps restore joint flexibility and prevent muscle adhesions. For patients with neurological disorders, they can stimulate neuromuscular responses, thereby improving gait and balance. For patients with chronic diseases, they can slow down muscle atrophy and enhance lower limb stability. For people with sports injuries, they can assist in repairing muscles and ligaments and reduce the risk of re-injury.

[0004] Currently, all existing lower limb rehabilitation training devices are pre-assembled and shipped as a single unit from the factory. However, transportation costs in the market are increasing, especially in e-commerce exports, where the transportation cost of large-volume products is calculated based on volume. This leads to higher transportation costs. Furthermore, if the product malfunctions and requires repair after it reaches the consumer, existing integrated devices usually require professional repair personnel with specialized tools to disassemble, replace, and repair parts. This increases the consumer's subsequent maintenance costs and also affects the consumer's user experience. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an electric lower limb rehabilitation training device that can reduce the initial transportation cost and the later maintenance cost, while also improving the user experience.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An electric lower limb rehabilitation training device includes a frame, a support member at the bottom of the frame, the support member being detachably connected to the frame, a mounting shaft rotatably mounted inside the frame, mounting plates coaxially fixed at both ends of the mounting shaft, connecting rods on the two mounting plates, mounting rods on the connecting rods, and a pedal sleeved on the mounting rod, the pedal being detachably connected to the mounting rod; the mounting rod is also detachably connected to the connecting rod.

[0008] By adopting the above technical solution, the support components can be removed from the frame and the pedals can be removed from the mounting rods during transportation. This effectively reduces the overall transportation volume of the device and thus reduces the overall transportation cost. In subsequent use by consumers, when replacement parts or repairs are needed, ordinary consumers can quickly disassemble the product's base plate and pedals themselves, eliminating the need for professional repair personnel to use specialized tools. This significantly reduces the consumer's later maintenance costs and further improves the user experience.

[0009] In some possible embodiments, a through mounting hole is provided on the support member in the vertical direction, a mounting bolt is slidably inserted in the mounting hole, and a fixing hole is provided at the bottom of the frame for threaded connection of the mounting bolt.

[0010] By adopting the above technical solution, when it is necessary to remove the support component from the frame, the support component can be removed from the frame as a whole by tightening the mounting bolts. After transportation or maintenance during later use, the support component can be reinstalled on the frame by tightening the mounting bolts. The operation is simple and convenient, which can improve the efficiency of disassembly and assembly and enhance the user experience.

[0011] In some possible embodiments, a mounting block is fixedly installed at the bottom of the frame, and a mounting groove for inserting the mounting block is opened at the top of the support member. The mounting hole is opened on the bottom wall of the mounting groove, and the fixing hole is opened at the bottom of the mounting block. A support ring is fixedly installed at the bottom of the support member. The support ring is coaxially arranged with the mounting hole. The inner diameter of the support ring is larger than the diameter of the mounting hole. The number of support rings is adapted to the number of mounting holes.

[0012] By adopting the above technical solution, when installing the support component, the mounting block is inserted into the mounting groove, and the side wall of the mounting block abuts against the inner wall of the mounting groove. This can achieve a preliminary positioning effect between the frame and the support component, ensuring that the mounting hole and the fixing hole are coaxial when connecting the support component and the frame. This facilitates the installation of mounting bolts, improves installation efficiency and user experience.

[0013] In some possible embodiments, the support includes a first base plate and a second base plate, which are detachably connected. A connector is provided on the first base plate to connect the first base plate and the second base plate. Both the first base plate and the second base plate have a hollowed-out groove at their bottoms, and a plurality of mutually perpendicular first and second reinforcing strips are provided in the hollowed-out groove.

[0014] By adopting the above technical solution, after the support component is disassembled from the frame, it is packaged and transported as a first base plate and a second base plate. This further reduces the transport volume of the support component during transportation, thereby further reducing the transportation cost of the device. At the same time, hollow grooves are opened at the bottom of the first and second base plates, which can effectively reduce the weight of the first and second base plates. The first and second reinforcing strips can improve the structural stability of the first and second base plates while reducing weight, thereby improving the overall support reliability of the device and preventing product deformation during transportation and subsequent use.

[0015] In some possible embodiments, the connector is configured as a locking block, with a first connecting hole on the side wall of the first base plate and a second connecting hole on the side wall of the second base plate. A connecting block is fixedly disposed horizontally on the inner wall of the second connecting hole, and a through locking hole is provided vertically on the connecting block. The connector is fixedly disposed vertically on the first base plate, and the connector slides through the locking hole. A stop block is fixedly disposed at the end of the connector, and the top of the stop block is used to abut against the bottom of the connecting block.

[0016] By adopting the above technical solution, when connecting the first base plate and the second base plate, the connecting block is first inserted into the first connecting hole, and then the connector is inserted into the locking hole. Subsequently, the top of the stop block abuts against the bottom of the connecting block, thereby limiting the position of the connector in the locking hole, thus completing the connection and installation of the first base plate and the second base plate. The operation is simple and convenient, and it has good practicality.

[0017] In some possible embodiments, the connector includes a first clamping piece, a second clamping piece, and a mounting portion. The mounting portion is fixedly disposed on a first base plate. The first and second clamping pieces are fixedly disposed vertically at the bottom of the mounting portion. The stop blocks are fixedly disposed at the bottom of the first and second clamping pieces. The sidewalls of the two stop blocks on a connector that are far apart from each other are set as inclined surfaces. The inclined surfaces are inclined at an acute angle in the direction of being far apart from each other. The inclined surfaces are used for sliding connection with the inner wall of the card hole.

[0018] By adopting the above technical solution, when connecting and installing the first base plate and the second base plate, the side wall of the stop block is set as an inclined surface, which makes it easier and faster to pass the first and second clips of the connector through the card hole, thus facilitating the installation of the first and second base plates and further improving the user experience.

[0019] In some possible embodiments, there are two connectors, which are respectively located at both ends of the first base plate near the second base plate. At least one insertion hole is provided on the side wall of the first base plate near the second base plate, and the insertion hole is located between the two connectors. A plug adapted to the insertion hole is fixedly provided on the side wall of the second base plate. A limiting member is provided on the first base plate to limit the position of the plug on the first base plate.

[0020] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0021] 1. The support components and pedals are detachable from the frame, which can effectively reduce the overall size, optimize packaging space, reduce logistics costs, and significantly reduce transportation costs. At the same time, ordinary consumers can also quickly disassemble the product's base plate and pedals themselves, thus eliminating the need to wait for professional repair personnel to use professional tools for disassembly and repair, significantly reducing consumers' later maintenance costs and further improving the consumer's user experience.

[0022] 2. When installing the support components, the mounting block is inserted into the inner wall of the mounting groove to provide initial positioning between the frame and the support components. This ensures that the mounting holes and fixing holes are coaxial when connecting the support components and the frame, which facilitates the installation of mounting bolts and improves installation efficiency and user experience.

[0023] 3. The hollow grooves at the bottom of the first and second base plates can effectively reduce the weight of the first and second base plates. The first and second reinforcing strips can improve the structural stability of the first and second base plates while reducing weight, thereby improving the overall support reliability of the device and preventing product deformation during transportation and subsequent use.

[0024] 4. When connecting and installing the first base plate and the second base plate, the side wall of the stop block is set as an inclined surface, which makes it easier and faster to pass the first and second clips of the connector through the locking holes, thus facilitating the installation of the first and second base plates and further improving the user experience.
