Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a leg adduction and abduction training device. Background Technology

[0002] Currently, limitations in human mobility are very common due to various reasons. To restore motor function, it is essential to train the restricted muscles and joints. Leg training, in particular, involves numerous muscle groups and joints, making it quite challenging.

[0003] Most leg training devices on the market use cylinders, hydraulic cylinders, or weights as resistance. The leg support and cylinders are connected by a chain. Users perform corresponding exercises to resist this resistance, depending on the body part being trained, thus achieving the desired training effect.

[0004] However, such leg trainers have too limited working modes and cannot meet the diverse training needs of users. Summary of the Invention

[0005] To at least partially address the problems existing in the prior art, the present invention provides a leg adduction and abduction trainer. The leg adduction and abduction trainer includes a frame, a drive unit, a leg support unit, and a transmission mechanism. The frame has a bottom support mounted on a mounting surface; the drive unit is mounted on the bottom support unit; the leg support unit has a first end and a second end, the second end being configured as the force-applying end during leg adduction and abduction training, and the second end is provided with an adapter adapted to leg fixation; and the drive unit is connected to the first end via the transmission mechanism; wherein the drive unit has a first operating mode and a second operating mode. In the first operating mode, a force is applied through the second end to drive the leg support unit, causing the drive unit to operate at a first power; in the second operating mode, the drive unit operates at a second power, causing the leg support unit to apply a force to the user.

[0006] The leg adduction and abduction trainer provided by this invention has a first working mode and a second working mode, which can provide users with better and more targeted training and meet various user needs. In the first working mode, unlike existing technologies that use cylinders, hydraulic cylinders, or weights as resistance, the resistance provided by the drive component is more precise and intelligent, preventing accidental injury during use. In the second working mode, the drive component generates force to rotate the leg support component, thereby inducing leg movement for training. This provides a passive training mode for users with severe muscle dysfunction, making it more user-friendly for those requiring rehabilitation training and broadening the overall applicability of the device.

[0007] For example, the adapter includes a connecting part and two fixing parts, the two fixing parts being respectively disposed on opposite ends of the connecting part, and the two fixing parts and the connecting part forming a groove for clamping the leg.

[0008] For example, the frame also includes a seat bracket connected to the bottom bracket, a seat is disposed on the seat bracket, a receiving space is formed between the seat bracket and the bottom bracket, and the drive unit and transmission mechanism are disposed within the receiving space.

[0009] For example, the leg support includes a straight section, a first curved section and a second curved section, the first curved section being connected between the straight section and the second curved section, the end of the straight section away from the first curved section being configured as a first end, and the end of the second curved section away from the first curved section being configured as a second end.

[0010] For example, the second curved segment is arc-shaped, and the first curved segment is connected to the middle of the second curved segment.

[0011] For example, there are two adapters, and the second curved segment has a first support end near the seat and a second support end away from the seat, with the two adapters respectively disposed on the first support end and the second support end.

[0012] For example, the first support end is not lower than the second support end.

[0013] For example, the seat is tilted upwards at 10° to 15° relative to a plane parallel to the mounting surface.

[0014] For example, there are two leg supports, which are located on both sides of the seat frame.

[0015] For example, the adapter is detachably connected to the second end.

[0016] A series of simplified concepts are introduced in the description of the invention, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0027] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0028] This invention provides a leg adduction and abduction training device, see [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The leg adduction and abduction trainer may include a frame 100, a drive unit 200, a leg support unit 300, a transmission mechanism 500, and an input device 600.

[0029] The input device 600 can be electrically connected to the driver 200 for adjusting the power of the driver 200. The input device 600 can be any device capable of inputting commands, such as a touch screen controller. Exemplarily, the input device 600 can also display the real-time power of the driver 200.

[0030] The frame 100 may have a bottom support 110 disposed on the mounting surface. The mounting surface may be any location where the leg adduction and abduction trainer needs to be placed. The bottom support 110 provides support for the overall structure of the leg adduction and abduction trainer. To facilitate the movement of the leg adduction and abduction trainer, the bottom support 110 may typically be equipped with casters 111. When moving the leg adduction and abduction trainer, the end of the bottom support 110 without casters 111 can be lifted. Since the other end is equipped with casters 111, the leg adduction and abduction trainer can be pushed more easily with the help of the casters 111.

[0031] The drive unit 200 can be mounted on the bottom bracket 110. The drive unit 200 can be in the form of a motor. Preferably, the drive unit 200 can be a permanent magnet brushless synchronous motor. Such a drive unit 200 has higher efficiency, higher power density, higher control precision, and less noise and vibration. When using a leg adduction and abduction trainer equipped with a drive unit 200 in the form of a permanent magnet brushless synchronous motor, the user experience is better.

[0032] The leg support 300 may have a first end 310 and a second end 320. The drive member 200 may be connected to the first end 310 of the leg support 300 via a transmission mechanism 500. The first end 310 of the leg support 300 may be in a form that facilitates connection with the transmission mechanism 500. The transmission mechanism 500 may be a four-bar linkage, a gear linkage, a rope linkage, a belt linkage, or other various types of transmission mechanisms. Under the action of the drive member 200, the transmission mechanism 500 may drive the first end 310 of the leg support 300 to rotate. In an embodiment where two leg supports 300 are symmetrically arranged on both sides of the bottom bracket 110, the transmission mechanism 500 may drive the two leg supports 300 to rotate symmetrically relative to the bottom bracket 110. Taking the transmission mechanism 500 as a gear transmission mechanism as an example, the end of the first end 310 can be provided with a gear, which can mesh with the transmission gear in the transmission mechanism 500. Under the action of the driving member 200, the transmission gear can drive the first end 310 to rotate, thereby driving the leg support member 300 to rotate. The second end 320 can be configured as the force application end during leg adduction and abduction training. The end of the second end 320 can be provided with any component that facilitates the user's leg to rest on. Specifically, the second end 320 can be provided with an adapter 400 adapted for leg fixation. The so-called adaptation for leg fixation means that the adapter 400 can be a sleeve or other various forms. Taking the sleeve-type adapter 400 as an example, the user's leg can be inserted into the adapter 400, and then the adapter 400 fixes the user's leg. Of course, there can be multiple adapters 400. For example, multiple adapters 400 can be used to fix the user's thigh and calf respectively. Moreover, for taller users, multiple adapters 400 may be needed to fix their legs. This invention does not limit the specific number of adapters 400. Setting up multiple adapters 400 can make the fixation of the user's legs more stable, and make it safer for the user to use such a leg adduction and abduction trainer.

[0033] The drive unit 200 can have a first working mode and a second working mode. In the first working mode, the second end 320 applies force to drive the leg support 300, causing the drive unit 200 to operate at a first power. In the second working mode, the drive unit 200 operates at a second power, causing the leg support 300 to apply force to the user. The first power can be zero, meaning that in the first working mode, only the user applies force to rotate the leg support 300. Alternatively, the first power can be non-zero; when the user applies force, the drive unit 200 applies a force opposite to the user's force at the first power, providing resistance for the user's training. Since this resistance is applied by the drive unit 200, it is more intelligent than using cylinders, hydraulic cylinders, or weights as resistance. For example, it can stop applying resistance when the user reaches exhaustion to prevent accidental injury during training. In the second working mode, the drive unit 200 exerts force to rotate the leg support 300, thereby assisting the user in performing leg adduction and abduction exercises. The first working mode can be understood as an active mode where the user primarily exerts force, while the second working mode can be understood as a passive mode where the drive component 200 primarily exerts force. During use, the leg adduction and abduction trainer can be adjusted to the desired mode according to the user's needs. For example, if the user has severe muscle weakness, the leg adduction and abduction trainer can be switched to the second working mode, allowing the leg support component 300 to drive the user in performing leg adduction and abduction movements. If the user has mild muscle weakness, the leg adduction and abduction trainer can be switched to the first working mode, allowing the user to exert force to train the muscles.

[0034] The leg adduction and abduction trainer provided by this invention has a first working mode and a second working mode, which can provide users with better and more targeted training and meet various user needs. In the first working mode, unlike existing technologies that use cylinders, hydraulic cylinders, or weights as resistance, the driving component 200 provides more precise and intelligent resistance, preventing accidental injury during use. In the second working mode, the driving component 200 drives the leg support component 300 to rotate, thereby inducing leg movement for training. This provides a passive training mode for users with severe muscle dysfunction, making it more user-friendly for those requiring rehabilitation training and broadening the overall applicability of the device.

[0035] In one embodiment of the present invention, see Figure 5 and Figure 6The adapter 400 may include a connecting part 410 and two fixing parts 420. The two fixing parts 420 may be respectively disposed at opposite ends of the connecting part 410, and the two fixing parts 420 and the connecting part 410 may form a groove 430 for clamping the leg. When using the leg adduction and abduction trainer, the user can place the leg in the groove 430. The connecting part 410 can provide support for the leg, and the two fixing parts 420 can enhance the leg-fixing effect of the adapter 400. During adduction and abduction training, regardless of whether the leg adduction and abduction trainer is in the first or second working mode, the adapter 400 receives and transmits force through the fixing parts 420. Compared to a sleeve-type adapter 400, the adapter 400 with grooves 430 makes it easier for the user to place the leg into the adapter 400; the user simply needs to place the leg into the adapter 400 through the opening in the groove 430. This type of leg adduction and abduction trainer is more convenient for users and provides a better user experience.

[0036] The adapter 400 can be detachably connected to the second end 320 via magnetic connection, threaded connection, snap-fit, or other various methods. Because different users have different leg sizes, or because the same user's body shape changes, the adapter 400 needs to be replaced to adapt to different leg sizes. This makes the adapter 400 on the leg adduction and abduction trainer easier to disassemble and replace. Such a leg adduction and abduction trainer can accommodate the needs of more users and also adapt to changes in the body shape of the same user, making it more widely applicable. During use, the adapter 400 has a higher degree of fit with the user's leg, resulting in a better user experience.

[0037] In one embodiment of the present invention, see Figure 1 , Figure 2 , Figure 3 and Figure 4The frame 100 may also include a seat support 120 connected to the bottom support 110. A seat 121 can be mounted on the seat support 120, and a receiving space 130 can be formed between the seat support 120 and the bottom support 110. The drive unit 200 and the transmission mechanism 500 can be disposed within the receiving space 130. When using the leg adduction and abduction trainer, the user can sit on the seat 121. The seat support 120 can provide support for the seat 121. At the same time, the seat support 120 and the bottom support 110 can support each other, enhancing the overall stability of the device. There is an accommodating space 130 between the seat support 120 and the bottom support 110. On the one hand, there is a gap between the seat support 120 and the bottom support 110, and the frame 100 is not a solid structure. The frame 100 is formed by multiple support rods such as the seat support 120 and the bottom support 110 being connected and supported by each other. Such a frame 100 is lighter in weight and can save materials and reduce costs. On the other hand, the drive component 200 and the transmission mechanism 500 are set in the accommodating space 130. The seat support 120 can protect the drive component 200 and the transmission mechanism 500. When the user uses the leg adduction and abduction trainer, he / she will not be blocked or interfered with by the drive component 200 and the transmission mechanism 500. At the same time, the user will not damage the drive component 200 and the transmission mechanism 500 due to accidental operation during training.

[0038] See details Figure 3The leg support 300 may include a straight section 330, a first curved section 340, and a second curved section 350. The first curved section 340 may be connected between the straight section 330 and the second curved section 350. The end of the straight section 330 away from the first curved section 340 may be configured as a first end 310, and the end of the second curved section 350 away from the first curved section 340 may be configured as a second end 320. The first end 310, which is the end of the straight section 330 away from the first curved section 340, may be in any form that facilitates connection with the transmission mechanism 500. For example, the transmission mechanism 500 may have an output shaft, and the first end 310 may have a sleeve that is fitted onto the output shaft and rotates with it. Thus, the transmission mechanism 500 may drive the leg support 300 to rotate. The first curved section 340 can be designed with any suitable structure and size as needed. For example, when the adapter 400 needs to be located at a lower height, the first curved section 340 can be designed as an extension of the straight section 330, or only tilted upward at a small angle relative to the straight section 330. For example, when the adapter 400 needs to be located at a higher height, the first curved section 340 can be designed with an upward arc shape so that the second curved section 350 is located at a higher height, and thus the adapter 400 connected to the second end 320 is also located at a higher height. The straight section 330 can provide support for the first curved section 340 and the second curved section 350. The second curved section 350 can be connected to an adapter 400. The second end 320, constructed at the end of the second curved section 350 away from the first curved section 340, can be any form that facilitates connection with the adapter 400. For example, for a sleeve-type adapter 400, the second end 320 can be a ring fitted onto the adapter 400. For a leg adduction and abduction trainer with multiple adapters 400, the second end 320 can have a bifurcated structure, which will be described in detail below. With such a leg support 300, the first curved section 340 can be designed into any suitable shape and size as needed, and the adapter 400 connected to the second end 320 can be located in any suitable position. This allows the overall device to meet the needs of more users and broaden its applicability.

[0039] See details Figure 3 , Figure 5 and Figure 6The second curved segment 350 can be arc-shaped, and the first curved segment 340 can be connected to the middle of the second curved segment 350. When the user places their leg on the adapter 400, the arc-shaped second curved segment 350 can minimize the impact on the user, for example, it can avoid the gastrocnemius muscle of the user's calf, making the user more comfortable when placing their leg on the adapter 400. The first curved segment 340 connecting to the middle of the second curved segment 350 can enhance the support effect of the first curved segment 340 on the second curved segment 350, preventing damage caused by uneven stress distribution within the second curved segment 350.

[0040] See Figure 5 and Figure 6 The adapter 400 can be two in number. The second bending section 350 can have a first support end 351 near the seat 121 and a second support end 352 away from the seat 121. The two adapters 400 can be respectively mounted on the first support end 351 and the second support end 352. The two adapters 400 can provide support and fixation for the user's thigh and calf respectively. Usually, providing support and fixation for the user's thigh and calf simultaneously is sufficient. Accordingly, the second bending section 350 can be provided with a first support end 351 and a second support end 352 to support the two adapters 400 respectively. Here, the first support end 351 and the second support end 352 can be plate-shaped or other various forms. Such a leg adduction and abduction trainer provides sufficient support and fixation for the user's legs while having a simpler structure and lower cost.

[0041] The first support end 351 may be no lower than the second support end 352. The adapter 400 connected to the first support end 351 can be used to support and fix the thigh, and the adapter 400 connected to the second support end 352 can be used to fix the lower leg. The first support end 351 and the second support end 352 are arranged at different heights, which is more in line with the normal human body structure, making it more comfortable for users and providing a better user experience.

[0042] See details Figure 3 The seat 121 can be tilted upwards at a rate of 10° to 15° relative to the plane parallel to the mounting surface. For example, the seat 121 can be tilted upwards at 10°, 12°, 13°, or 15° relative to the plane parallel to the mounting surface. As shown in the figure, the angle between the seat 121 and the plane parallel to the mounting surface is α, preferably α can be 13°. This angle between the seat 121 and the plane parallel to the mounting surface allows the user to lower their center of gravity when sitting on the seat 121, making leg training more stable and improving the training effect.

[0043] To accommodate training on one leg, a single leg support 300 can be used. Alternatively, two leg supports 300 can be used, located on either side of the seat support 120. Using two leg supports 300 offers wider applicability and meets the needs of most situations.
