Description

Technical Field

[0001] This utility model relates to the field of health equipment technology, specifically to a foot pedal fixing device and a rehabilitation training device. Background Technology

[0002] The main principle of rehabilitation therapy is to grasp the patient's initiative and motivation in learning, which is key to determining the effectiveness of rehabilitation training. The earlier the function of the hemiplegic limbs is restored, the better the comprehensive recovery of functions such as cognition and language. Traditional rehabilitation training models often cannot guarantee the intensity, endurance, and standardization of training, and it is difficult to fully understand and grasp the mechanism of action of exercise, thus affecting the quality and efficiency of rehabilitation. Therefore, rehabilitation training equipment has emerged, providing patients with a more scientific, efficient, and safe way of rehabilitation training.

[0003] However, the foot pedal fixation device of traditional rehabilitation training equipment has the following drawbacks:

[0004] First, it cannot restrict forward and backward sliding. Existing devices mostly fix the foot in the left and right direction with straps, but there is no effective limit in the forward and backward direction, which causes the foot to slide during training and cause injuries such as plantar fasciitis and Achilles tendonitis. Second, it has poor adaptability: the fixed size foot pedal fixing device cannot adapt to different foot lengths, affecting the user experience and training effect. Third, it cannot be completed with one hand and requires the help of others, which limits the convenience of adjustment during use. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a foot pedal fixing device and rehabilitation training equipment that can be easily adjusted in the forward and backward direction of the foot, has good adaptability, and is easy to adjust with one hand.

[0006] To achieve the above and other related objectives, this utility model provides a foot pedal fixing device, comprising:

[0007] The foot pedal body is designed to support the user's feet.

[0008] A limiting component is movably mounted on the foot pedal body and is used to limit the forward and backward sliding of the foot;

[0009] An adjustment mechanism is provided, connecting the foot pedal body and the limiting component, the adjustment mechanism being configured to adjust the length of the limiting component itself and / or adjust the position of the limiting component on the foot pedal body.

[0010] As an optional embodiment of this case, the limiting component includes a forefoot limiting part and a heel limiting part;

[0011] The forefoot limiting part and / or the heel limiting part are slidably connected to the foot pedal body along a first direction, the first direction being the front-back direction of the foot on the foot pedal body.

[0012] As an optional embodiment of this case, the forefoot limiting part is slidably connected to the foot pedal body along the first direction via a guide member, and the guide member is disposed at the bottom and / or both sides of the foot pedal body.

[0013] As an optional embodiment of this case, the adjustment mechanism includes a traction component connected to the forefoot limiting portion, the traction component comprising:

[0014] A traction rope passes through the foot pedal body in a first direction and connects to the forefoot limiting part;

[0015] A tightening mechanism is provided on the foot pedal body and connected to the traction rope, the tightening mechanism being configured to tighten or loosen the traction rope.

[0016] As an optional embodiment of this case, an elastic reset component is provided between the limiting component and the foot pedal body.

[0017] As an optional embodiment of this case, the adjustment mechanism includes an adjustment component connected to the heel limiting portion, the adjustment component including:

[0018] A connecting bracket is disposed at the rear of the foot pedal body, and the connecting bracket is provided with a threaded hole along the first direction;

[0019] A threaded rod passes through the threaded hole and connects to the heel limiting part.

[0020] As an optional embodiment of this case, a nut is provided on the connecting bracket, and a threaded hole is provided in the nut.

[0021] As an optional embodiment of this case, the forefoot limiting part has a hollow structure.

[0022] As an optional embodiment of this case, the adjustment mechanism includes visual scale markings for indicating the adjustment amount of the limiting component.

[0023] To achieve the above-mentioned objectives and other related objectives, this utility model provides a rehabilitation training device, including the aforementioned foot pedal fixing device.

[0024] In summary, this invention effectively solves the problems of incorrect training posture and foot injury caused by the inability of traditional foot pedal structures to restrict forward and backward sliding of the foot through the coordinated work of the foot pedal body, limiting component, and adjustment mechanism. Addressing the drawback of fixed-size foot pedal structures being difficult to adapt to different user foot lengths and affecting training effectiveness, the adjustment mechanism of this design can adjust the length of the limiting component and / or its position on the foot pedal body to accommodate different foot sizes and positions. When the user's foot slides forward or backward, the limiting component can effectively limit the amount of foot sliding, thereby avoiding or reducing the incidence of plantar fasciitis. The foot pedal fixing device of this invention has strong adaptability, can fit the foot size of most people, and is easy to wear and adjust, effectively improving ease of use; furthermore, the user can complete the foot limiting with one hand without assistance, greatly expanding the convenience of adjusting and using related equipment.

[0037] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in this invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to those described, used, or made of materials in the embodiments of this invention.

[0038] Please see Figure 1-3 This utility model provides a foot pedal fixing device, including a foot pedal body 1, a limiting component 2, and an adjusting mechanism 3; the foot pedal body 1 is used to support the user's foot; the limiting component 2 is movably disposed on the foot pedal body 1 and is used to limit the forward and backward sliding of the foot; the adjusting mechanism 3 connects the foot pedal body 1 and the limiting component 2, and the adjusting mechanism 3 is configured to adjust the length of the limiting component 2 itself and / or adjust the position of the limiting component 2 on the foot pedal body 1 to adapt to different foot sizes and foot positions.

[0039] It should be noted that the foot pedal body 1 is made of materials that meet the usage requirements, such as steel, high-strength engineering plastics (e.g., nylon), aluminum alloy, fabric, or flexible rubber. The surface of the foot pedal body 1 that contacts the foot has anti-slip textures to prevent toes from slipping. The limiting component 2 is generally arranged along the front-back direction of the foot on the foot pedal body 1. The limiting component 2 may include, for example, a U-shaped limiting frame. The limiting component 2 can be an integral structure or a split structure. For example, the limiting component 2 includes a forefoot limiting part 21, a heel limiting part 22, and a side limiting part. For example, when the limiting component 2 is a split structure, the forefoot limiting part 21 and / or the heel limiting part 22 and / or the side limiting part are respectively movably connected to the foot pedal body 1. The limiting component 2 has polyurethane cushioning pads on both sides to reduce the impact force when the user's feet move. It should be understood that the design shape of the foot pedal body 1 and the limiting component 2 should fully consider ergonomic principles to fit the foot contours of different users and reduce foot fatigue. For example, the adjustment mechanism 3 can be a gear and rack adjustment mechanism, a hydraulic adjustment mechanism, a screw adjustment mechanism, etc., which can realize the length adjustment of the limiting component 2 itself and / or the position adjustment of the limiting component 2 on the foot pedal body 1. For example, the gear and rack adjustment mechanism consists of a gear and a rack meshing with it. By rotating the gear, the rack will move accordingly, thereby driving the connected limiting component 2 or foot pedal body 1 to adjust its position. This allows for precise control of the length and / or position of the limiting component 2 to adapt to changes in foot size and position requirements of different patients. For example, the hydraulic adjustment mechanism utilizes the incompressibility of liquid to transmit power and achieve position adjustment. The hydraulic adjustment mechanism consists of components such as a hydraulic cylinder, piston, oil pipe, and control valve. When the user needs to adjust the length or position of the limiting component 2, the control valve controls the flow direction and flow rate of the hydraulic oil, pushing the piston to move, thereby driving the limiting component 2 to extend, retract, or move. For example, the screw adjustment mechanism mainly relies on the rotational motion of the screw thread to achieve length and / or position adjustment. The screw adjustment mechanism consists of a screw, a nut and related connecting parts. When the screw rotates relative to the nut, due to the action of the screw thread, the screw will move along the axial direction, thereby driving the connected parts to adjust their position.

[0040] This invention solves the technical problem that traditional foot pedal structures cannot restrict forward and backward sliding of the foot, leading to incorrect training posture and foot injuries, through the coordinated operation of the foot pedal body 1, the limiting component 2, and the adjustment mechanism 3. Since fixed-size foot pedal structures cannot adapt to different user foot lengths, affecting training effectiveness, this invention uses the adjustment mechanism 3 to adjust the length of the limiting component 2 and / or its position on the foot pedal body 1 to adapt to different foot sizes and positions. When the user's foot slides forward or backward, the limiting component 2 can effectively limit the amount of foot sliding, avoiding or reducing the incidence of plantar fasciitis. The foot pedal fixing device of this invention has good adaptability, can fit the foot size of most people, and is easy to wear and adjust, effectively improving ease of use.

[0041] Please see Figure 4 or Figure 5 As one optional embodiment of this utility model, the limiting component 2 is slidably connected to the foot pedal body 1 via the guide rail 24. The guide rail 24 is symmetrically distributed and is fixedly connected to the bottom or both sides of the foot pedal body 1. The limiting component 2 is slidably connected to the guide rail 24 via the guide member 23 to ensure that the forefoot limiting part 21 remains horizontal during movement.

[0042] Please see Figure 1 As one of the optional embodiments of this utility model, the limiting component 2 includes a forefoot limiting part 21 and / or a heel limiting part 22.

[0043] The forefoot limiting part 21 and / or the heel limiting part 22 are slidably connected to the foot pedal body 1 along a first direction, which is the front-back direction of the foot on the foot pedal body 1.

[0044] It should be noted that the forefoot limiting part 21 and the heel limiting part 22 in this case can be flexibly adjusted in position on the foot pedal body 1 according to the user's needs. For example, the forefoot limiting part 21 and / or the heel limiting part 22 can slide forward or backward in the first direction, so that the user can adjust the position of the limiting part according to personal needs and foot size, thereby obtaining more comfortable foot support and a more enveloping feeling, improving the versatility and practicality of the product; and by precisely adjusting the position of the forefoot limiting part 21 and / or the heel limiting part 22, the stability of the user on the foot pedal fixing device can be ensured, reducing safety hazards caused by foot slippage.

[0045] Please see Figure 4 or Figure 5 As one of the optional embodiments of this utility model, the forefoot limiting part 21 is slidably connected to the foot pedal body 1 along the first direction through the guide member 23, and the guide member 23 is disposed at the bottom and / or both sides of the foot pedal body 1.

[0046] It should be noted that the foot pedal body 1 is provided with a guide rail 24, and the guide member 23 is a slider or guide rod that is slidably connected to the guide rail 24. The guide rail 24 is fixed to the bottom of the foot pedal body 1 by welding, bolts, screws or injection molding, or integrated into the foot pedal body 1 to achieve a hidden and compact structural design.

[0047] Please see Figure 1-3 As one of the optional embodiments of this utility model, the adjustment mechanism 3 includes a traction component 31 connected to the forefoot limiting part 21, and the traction component 31 includes a traction rope 311 and a tightening mechanism 312.

[0048] The traction rope 311 passes through the foot pedal body 1 in a first direction and is connected to the forefoot limiting part; the tightening mechanism 312 is disposed on the foot pedal body 1 and connected to the traction rope 311, and the tightening mechanism 312 is configured to tighten or loosen the traction rope 311.

[0049] It should be noted that the traction rope 311 is, for example, a nylon rope or a traction rope or a steel wire rope woven from Kevlar fiber, with a diameter of approximately 3 mm. Both ends are connected to the forefoot limiting part 21 via stainless steel clips. One or multiple traction ropes 311 can be used. For example, when only one traction rope 311 is used, both ends can pass through the bottom or sides of the foot pedal body 1 along a first direction and connect to the forefoot limiting part 21. When the traction rope 311 is fully tightened, the forefoot limiting part 21 contacts the part of the traction rope 311 that passes through the foot pedal body 1. The main function of the traction rope 311 is to transmit the tension of the tightening mechanism 312, allowing the forefoot limiting part 21 to move back and forth along the foot pedal body 1. By adjusting the length of the traction rope 311, the position of the forefoot limiting part 21 can be flexibly changed to accommodate different users' foot sizes and shapes. The tightening mechanism 312 is positioned at a suitable location on the foot pedal body 1 and is tightly connected to the traction rope 311. The tightening mechanism 312 includes one or more elements for controlling the tension of the traction rope 311, such as a rotary buckle, a rotatable snap, a rotary button, a rotary buckle, a rotary pressure buckle, a knob, a pulley, or a knob, to facilitate user operation and ensure a smooth and accurate tightening process. For example, the tightening mechanism 312 can be a worm gear tightening mechanism, which includes a worm, a worm wheel, and a crank handle. The worm is connected to the traction rope 311. When the crank handle is turned, the worm rotates and drives the worm wheel to rotate. Due to the meshing relationship between the worm and the worm wheel, the worm wheel also rotates. Depending on the rotation direction of the worm wheel and the thread structure, the traction rope 311 will be tightened or loosened accordingly. Please refer to [link / reference]. Figure 2-3 or Figure 7For example, the tightening mechanism 312 is a rotating button 3122 assembly. The rotating button 3122 includes a base limiting part 3121 connected to the foot pedal body 1 and a rotating button 3122. The traction rope 311 passes through the rotating button 3122 in the radial direction. The rotating button 3122 is rotatably limited on the base limiting part 3121. A limit block is provided between the rotating button 3122 and the base limiting part 3121. When the rotating button 3122 is tightened, the traction rope 3122 is tightened. When the rotating button 3122 and the base limiting part 3121 are close together in the axial direction of the rotating button 3122, the engagement of the limiting block can prevent the rotating button 3122 from being limited. When the rotating button 3122 and the base limiting part 3121 are far apart in the axial direction of the rotating button 3122, the rotating button 3122 disengages from the limiting block of the base limiting part 3121, which facilitates the rotation of the rotating button 3122 to loosen or tighten the traction rope 311. The tightening mechanism 312 can have a built-in planetary gear set to improve the efficiency of tightening or loosening. Clockwise rotation tightens the rope, and counterclockwise rotation locks it through a ratchet mechanism to prevent backlash, thereby improving the convenience of one-handed operation for the user. Furthermore, the rotating button 3122 can be replaced with an electric knob driven by a micro motor (e.g., power W5), and can have a built-in chip to support remote control via a mobile app or the app that comes with the rehabilitation training equipment; thus solving the problem of laborious manual adjustment and poor user experience, without requiring complicated tools or skills. This invention improves operational convenience and adjustment efficiency of the foot pedal fixing device through the setting of the traction rope 311 and the tightening mechanism 312.

[0050] Please see Figure 5 As one of the optional embodiments of this utility model, an elastic reset component 25 is provided between the limiting component 2 and the foot pedal body 1, which is used to reset the forefoot limiting part 21 to the initial position when the traction component 31 is released.

[0051] It should be noted that the elastic reset component 25 is, for example, a spring, an elastic rope, or other elastic component that meets the usage requirements. The two ends of the spring are fixed to the limiting component 2 and the foot pedal body 1 by retaining rings, forming a bidirectional elastic constraint. Since traditional devices require manual operation for reset, which is inefficient, the limiting component 2 in this invention can automatically reset via the elastic reset component 25, improving reset efficiency and thus enhancing ease of operation.

[0052] Please see Figure 5 As one optional embodiment of this utility model, the elastic reset component 25 is a spring, one end of which is fixed to the limiting component 2 and the other end is fixed to the foot pedal body 1. The spring is a spring sleeve structure and may have an internal guide rod to prevent the spring from bending laterally. A buffer rubber pad is added between the spring and the limiting component 2 to reduce impact noise.

[0053] Please see Figure 1-3 As one optional embodiment of this utility model, the adjustment mechanism 3 includes an adjustment component 32 connected to the heel limiting part 22. The adjustment component 32 includes a connecting frame 321 and a threaded rod 322. The connecting frame 321 is disposed at the rear of the foot pedal body 1, and the connecting frame 321 is provided with a threaded hole 3211 along a first direction. The threaded rod 322 passes through the threaded hole 3211 and is connected to the heel limiting part 22.

[0054] It should be noted that the threaded hole 3211 can be directly set on the connecting frame 321, or it can be fixed to the connecting frame 321 by a nut to form the threaded hole 3211; the threaded rod 322 is threadedly engaged with the threaded hole 3211, and the heel limiting part 22 can be moved along the first direction by rotating the threaded rod 322. This utility model solves the problem that the heel fixing position of the traditional foot pedal fixing device is singular and cannot adapt to different foot shapes and training needs. This utility model realizes the heel position is adjustable by setting the heel adjustment component, and improves the convenience of use and the efficiency of adjustment.

[0055] Please see Figure 1 Alternatively, in one of the optional embodiments of this utility model, the forefoot limiting part 21 has a hollow structure.

[0056] It should be noted that the hollow structure in this case can be, for example, a honeycomb hollow design, made of aluminum alloy, plastic, leather, carbon fiber composite material, or fabric, etc., which reduces most of the weight and makes the overall structure lightweight. The hollow structure allows air to circulate freely in the forefoot area, which helps to keep the feet dry, reduce sweating and odor. By improving ventilation, the hollow structure can effectively reduce the accumulation of moisture in the feet, thereby reducing foot problems caused by a damp environment, such as fungal infections. At the same time, the hollow structure allows the user to clearly see the wearing situation of the forefoot, making it easier for the user to put on the forefoot limiting part 21.

[0057] As one optional embodiment of the present invention, the adjustment mechanism 3 includes visual scale markings for indicating the adjustment amount of the limiting component 2.

[0058] It should be noted that the visual scale markings can be laser-engraved on the surface of the guide rail 24, slide rail, or tightening mechanism 312, and coated with fluorescent paint (visible at night). A digital display module integrating an LCD screen can also be set to display the adjustment amount and remaining travel in real time, thus solving the problem that users have difficulty intuitively grasping the adjustment progress, which can easily lead to over- or under-adjustment. This invention, through the setting of visual scale markings, allows users to remember the current adjustment size after the first trial of the foot pedal fixing device, facilitating quick adjustments next time (provided the foot size does not increase excessively), thereby improving ease of use.

[0059] The foot pedal fixing device in this case is based on ergonomic data, allowing the adjustment range to cover most or all user needs. It can achieve stepless adjustment using a telescopic or threaded guide rod lock, thus solving the problem of narrow adjustment range in traditional foot pedal fixing devices that cannot meet the needs of special groups, and improving the applicability of the foot pedal fixing device.

[0060] This utility model also provides a rehabilitation training device, including the foot pedal fixing device, wherein the rehabilitation training device is, for example, a lower limb joint training machine, a gait training machine, an elliptical machine, a stationary bike, or other devices that meet the usage requirements.

[0061] It should be noted that, for example, the foot pedal fixing device of the lower limb joint training machine or gait training machine is linked to the gait simulation module, automatically adjusting the limiting pressure according to the patient's muscle strength. The elliptical trainer can integrate a heart rate sensor to dynamically adjust the tightness of the limiting device according to the user's heart rate. The exercise bike can match the resistance level through a torque sensor. In addition, the foot pedal fixing device can also be applied to rowing machines, stair climbers, and other equipment.

[0062] In this case, the foot pedal fixation device effectively secures the user's foot, preventing slippage or displacement during training, thus preventing instability and accidental injury, protecting key areas such as the ankle joint, and reducing the risk of sports injuries. The length of the foot pedal fixation device can be adjusted according to the user's individual needs to meet different training requirements and achieve more precise training control. The foot pedal fixation device is ergonomically designed, allowing the user to maintain a comfortable posture during training and reducing fatigue. The limiting component 2 makes training more stable, improving comfort and convenience. Long-term use of this device for training can effectively exercise the muscles of the thigh, calf, and ankle joints, enhancing athletic ability and stability. The length of the foot pedal fixation device is adjusted by the cooperation of the heel adjustment component, traction rope 311, rotating button 3122, and slide rail. This foot pedal fixation device is highly effective in improving exercise stability and safety, optimizing the user experience, and adapting rehabilitation training equipment to different user needs. These effects have a positive impact on patient rehabilitation and fitness enthusiasts' training process, helping to improve training results, reduce sports risks, and improve the user's physical health.

[0063] In summary, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0064] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
