Abstract
Description
Technical Field
[0001] This application relates to the field of rehabilitation equipment, and in particular to a rehabilitation foot pedal structure, as well as a method of using the rehabilitation foot pedal structure. Background Technology
[0002] Leg injuries are a common type of trauma in clinical practice, and if proper rehabilitation training is not provided after an injury, it may leave lifelong sequelae.
[0003] Currently, most leg rehabilitation devices on the market use a method similar to bicycle pedals. This type of device can only exercise the extensor muscles of the injured person's leg, and the range of motion is small. The injured person's leg joints cannot be fully bent or extended. Therefore, patients still need other devices to exercise other parts of the leg during rehabilitation.
[0004] Therefore, there is a need for a rehabilitation foot pedal structure and its usage method. Summary of the Invention
[0005] To address the problem that existing leg rehabilitation devices are insufficient for providing adequate leg exercise for rehabilitation participants, this application provides a rehabilitation foot pedal structure and its usage method.
[0006] The first aspect of this application provides a rehabilitation foot pedal structure, which adopts the following technical solution: A rehabilitation foot pedal structure includes a seat unit, a pedal, a damping unit, and a bracket. The damping unit is disposed on the bracket and includes a first piston cylinder, a second piston cylinder, a connecting pipe, and a regulating valve. The rod chambers of the first piston cylinder and the second piston cylinder face the seat unit, and the rodless chambers of the first piston cylinder and the second piston cylinder are connected through the connecting pipe. The regulating valve is provided in the connecting pipe so that the flow area of the connecting pipe can be adjusted through the regulating valve.
[0007] The piston rod of the first piston cylinder and the piston rod of the second piston cylinder are each provided with a pedal, and the first piston cylinder and the second piston cylinder are located in the same plane as the seat cushion of the seat unit.
[0008] By adopting the above technical solution, leg exercises in a seated position can effectively reduce the burden on the legs due to body weight, making it suitable for low-intensity leg exercises. Compared with bicycle-style rehabilitation equipment, placing the first and second piston cylinders and the seat cushion of the seat unit on the same plane allows the rehabilitation personnel to still have a relatively large range of flexion and extension when stepping on the pedals of the first and second piston cylinders in a seated position. This enables the rehabilitation personnel's ankle, knee, and even hip joints to be effectively moved and exercised.
[0009] Furthermore, the pedal is equipped with straps.
[0010] By adopting the above technical solution, the feet of rehabilitation personnel can be tied to the pedal, which can prevent the feet from slipping off the pedal and causing injury during exercise. Tying the feet to the pedal also makes it easier for the rehabilitation personnel to apply pulling force to the pedal. When the rehabilitation personnel apply pushing force to the pedal, the thigh anterior muscles of their legs contract and the thigh posterior muscles relax. When applying pulling force to the pedal, the thigh anterior muscles relax and the thigh posterior muscles contract, so that both the thigh anterior and thigh posterior muscles can be well relaxed, resulting in better exercise effects.
[0011] Furthermore, a connecting shaft is provided between the pedal and the piston rod. The connecting shaft includes a fixed section and a pin section. The fixed section is a square column. The end of the piston rod is provided with a pin hole that matches the pin section. The pedal is hinged to the pin section.
[0012] By adopting the above technical solution, the pedal can be rotated, so that the pedal can move with the ankle joint when the rehabilitation personnel flex and extend their legs.
[0013] Furthermore, the bracket is provided with a gear and a brake. The gear is located between the piston rods of the first piston cylinder and the second piston cylinder and is hinged to the bracket. The piston rods of the first piston cylinder and the second piston cylinder are each provided with a rack that meshes with the gear. The brake includes a push cylinder and a locking block provided on the push rod of the push cylinder. The push cylinder can drive the locking block to move closer to or away from the gear, and the locking block can mesh with the gear when it is close to the gear.
[0014] By adopting the above technical solution, the locking of the first piston cylinder and the second piston cylinder can be achieved through the cooperation of gears and brakes.
[0015] Furthermore, each of the pin holes is provided with a pressure sensor on the hole wall near the seat unit and on the hole wall away from the seat unit, and each of the pressure sensors is communicatively connected to the controller so as to transmit pressure information to the controller. The controller is also communicatively connected to the push cylinder, and the controller is configured to control the movement direction of the locking block according to the pressure information.
[0016] By adopting the above technical solution, the pressure sensor on the hole wall near the seat unit can measure the pulling force applied by the rehabilitation personnel's legs to the pedal, and the pressure sensor on the hole wall away from the seat unit can measure the pushing force applied by the rehabilitation personnel's legs to the pedal. The controller can determine the pulling or pushing force applied by the rehabilitation personnel's left and right legs to the corresponding piston cylinders. Thus, when the ratio of the pulling force applied by one leg to the pushing force applied by the other leg reaches a set value, the piston rods of the first and second piston cylinders can move. When the ratio of the pulling force applied by one leg to the pushing force applied by the other leg does not reach the set value, the piston rods of the first and second piston cylinders will be locked, so that the rehabilitation personnel must exercise according to the set force application pattern in order to achieve better exercise results.
[0017] Furthermore, a slide rail is provided below the bracket, the bracket is connected to the slide rail, and can slide along the slide rail to approach or move away from the seat unit. The first piston cylinder, the second piston cylinder, and the connecting pipe are all provided on the bracket. Multiple positioning holes are also provided on the bracket along the extension direction of the slide rail. The bracket is provided with a limiting hole, and a limiting pin can pass through the limiting hole and be inserted into the positioning hole.
[0018] By adopting the above technical solution, the distance between the damping unit and the seat unit can be adjusted, thus adapting to rehabilitation personnel of different heights.
[0019] Furthermore, the regulating valve is an electro-hydraulic proportional valve.
[0020] By adopting the above technical solution, electro-pneumatic regulation of the regulating valve can be realized, thereby enabling electronic control regulation of the damping force.
[0021] Furthermore, the seat unit also includes a pair of armrests.
[0022] By adopting the above technical solutions, it is easier for rehabilitation personnel to maintain their body balance.
[0023] The second aspect of this application provides a method of using a rehabilitation foot pedal structure, which adopts the following technical solution: A method of using a rehabilitation foot pedal structure, implemented by applying one of the rehabilitation foot pedal structures in the above-mentioned technical solution, includes the following steps:
[0024] Damping force adjustment steps: Adjust the regulating valve to obtain a suitable damping strength;
[0025] Foot binding procedure: Use straps to bind the rehabilitation participant's feet to the pedal;
[0026] Exercise steps: The rehabilitation participant applies force with both legs simultaneously, so that when the left leg applies a pushing force to the first piston cylinder, the right leg applies a pulling force to the second piston cylinder, or when the left leg applies a pulling force to the first piston cylinder, the right leg applies a pushing force to the second piston cylinder.
[0027] By adopting the above technical solution, the feet of rehabilitation personnel are tied to the pedal, which makes it easier for them to apply pulling force to the pedal. When the rehabilitation personnel apply pushing force to the pedal, the femoral anterior muscles of their legs contract and the hamstring muscles relax. When they apply pulling force to the pedal, the femoral anterior muscles relax and the hamstring muscles contract. This allows both the femoral anterior and hamstring muscles to be well relaxed, resulting in better training effects.
[0028] Furthermore, during the exercise process, each of the pressure sensors can detect the pushing or pulling force exerted by the rehabilitation personnel's legs on the first piston cylinder and the second piston cylinder. When the ratio of the pulling force value to the pushing force value is within a set range, the controller controls the push cylinder to move the locking block away from the gear. When the ratio of the pulling force value to the pushing force value is outside the set range, the controller controls the push cylinder to move the locking block to abut against the gear.
[0029] By adopting the above technical solutions, it is possible to correct the leg exertion habits of rehabilitation personnel, so that the contraction and relaxation of leg muscles are roughly equal, thereby achieving better training results.
[0030] In summary, this application includes at least one of the following beneficial effects:
[0031] 1. Firstly, performing leg exercises in a seated position can effectively reduce the burden on the legs due to body weight, making it suitable for low-intensity leg exercises. Compared to bicycle-style rehabilitation equipment, placing the first and second piston cylinders and the seat cushion of the seat unit on the same plane allows the rehabilitation personnel to still have a relatively large range of flexion and extension when stepping on the pedals of the first and second piston cylinders in a seated position. This enables the rehabilitation personnel to effectively move and exercise their ankle, knee, and even hip joints.
[0032] 2. Tying the feet of rehabilitation participants to the pedals makes it easier for them to apply pulling force to the pedals. When pushing the pedals, the quadriceps muscles in the legs contract and the hamstring muscles relax. When pulling the pedals, the quadriceps muscles relax and the hamstring muscles contract. This allows both the quadriceps muscles to relax well, resulting in better training effects. Attached Figure Description

[0039] Figure 1 This is a perspective view of a rehabilitation foot pedal structure according to this application. Figure 2 This is a top view of a rehabilitation foot pedal structure according to this application; see below. Figure 1 and Figure 2 The first aspect of this application provides a rehabilitation foot pedal 2 structure including a seat unit 1, a pedal 2, a damping unit 3, and a bracket 4. The damping unit 3 is disposed on the bracket 4 and includes a first piston cylinder 31, a second piston cylinder 32, a connecting pipe 33, and a regulating valve 34. The rod chambers of the first piston cylinder 31 and the second piston cylinder 32 are both facing the seat unit 1, and the rodless chambers of the first piston cylinder 31 and the second piston cylinder 32 are connected through the connecting pipe 33. The connecting pipe 33 is provided with a regulating valve 34 so that the flow area of the connecting pipe 33 can be adjusted through the regulating valve 34. The end of the piston rod of the first piston cylinder 31 and the end of the piston rod of the second piston cylinder 32 are each provided with a pedal 2, and the first piston cylinder 31 and the second piston cylinder 32 are disposed in the same plane as the seat cushion of the seat unit 1.
[0040] The seat unit 1 allows rehabilitation personnel to perform leg exercises in a seated position, effectively reducing the burden of their own weight on their legs. This enables them to perform lower-intensity leg exercises, preventing the exercise from having the opposite effect due to excessive leg strain. Compared to bicycle-style rehabilitation equipment, the first piston cylinder 31 and the second piston cylinder 32 are placed on the same plane as the seat cushion of the seat unit 1. This allows the rehabilitation personnel to still have a relatively large range of flexion and extension when stepping on the pedals 2 on the first piston cylinder 31 and the second piston cylinder 32 in a seated position. This allows the rehabilitation personnel's ankle, knee, and even hip joints to be effectively moved and exercised.
[0041] Figure 3 yes Figure 2 Cross-sectional view along the AA direction. Figure 4 yes Figure 2 Cross-sectional view along the BB direction, see Figure 3 and Figure 4 A connecting shaft 5 is provided between the pedal 2 and the piston rod. The connecting shaft 5 includes a fixed section 51 and a pin section 52. The fixed section 51 is a square column. The end of the piston rod is provided with a pin hole that matches the pin section 52. The pedal 2 is hinged to the pin section 52, thereby realizing the hinge between the pedal 2 and the piston rod. This allows the pedal 2 to move when the rehabilitation personnel flex and extend their legs and rotate their ankle joints. This not only makes it convenient for rehabilitation personnel to apply force during exercise, but also allows the rehabilitation personnel's ankle joints to rotate, thereby achieving the purpose of exercising the ankle joint.
[0042] A strap 21 is provided on the pedal 2 to bind the feet of the rehabilitation personnel to the pedal 2, thereby preventing the feet from slipping off the pedal 2 during exercise and causing injury. Binding the feet to the pedal 2 also makes it easier for the rehabilitation personnel to apply pulling force to the pedal 2. When the rehabilitation personnel apply pushing force to the pedal 2, the femoral anterior muscles of their legs contract and the hamstring muscles relax. When applying pulling force to the pedal 2, the femoral anterior muscles of their legs relax and the hamstring muscles contract. This allows both the femoral anterior and hamstring muscles to be well relaxed, resulting in better exercise effects.
[0043] See Figure 1 and Figure 2 The bracket 4 is equipped with a gear 41 and a brake 42. The gear 41 is located between the piston rods of the first piston cylinder 31 and the second piston cylinder 32 and is hinged to the bracket 4. The piston rods of the first piston cylinder 31 and the second piston cylinder 32 are each equipped with a rack 35 that meshes with the gear 41. The brake 42 includes a push cylinder 421 and a locking block 422 located on the push rod of the push cylinder 421. The push cylinder 421 can drive the locking block 422 to move closer to or away from the gear 41, and the locking block 422 can mesh with the gear 41 when it is close to the gear 41.
[0044] Figure 5 yes Figure 4 See the enlarged view of region C in the middle. Figure 4 and Figure 5 A pressure sensor 7 is provided on the hole wall near the seat unit 1 and on the hole wall away from the seat unit 1 in each pin hole. Figure 5 (Taking only the pin hole of the first piston cylinder 31 as an example), and each pressure sensor 7 is connected to the controller to transmit pressure information to the controller. The controller is also connected to the push cylinder 421. The controller is configured to control the movement direction of the locking block 422 according to the pressure information. The pressure sensor 7 on the hole wall near the seat unit 1 can measure the pulling force applied by the rehabilitation personnel's legs to the pedal 2. The pressure sensor 7 on the hole wall away from the seat unit 1 can measure the pushing force applied by the rehabilitation personnel's legs to the pedal 2. The controller can determine the pulling or pushing force applied by the rehabilitation personnel's left and right legs to the corresponding piston cylinders based on this.
[0045] For example, the first piston cylinder 31 corresponds to the left leg, and the second piston cylinder 32 corresponds to the right leg. When the left leg extends and the right leg retracts, the pressure sensor 7 on the hole wall of the pin hole of the first piston cylinder 31 near the seat unit 1 has a value of 0, while the pressure sensor 7 on the hole wall away from the seat unit 1 has a value of A; the pressure sensor 7 on the hole wall of the pin hole of the second piston cylinder 32 near the seat unit 1 has a value of B, while the pressure sensor 7 on the hole wall away from the seat unit 1 has a value of 0. The controller can determine whether it is necessary to control the push cylinder 421 to drive the locking block 422 closer to the gear based on the ratio between the pulling force and the induction force, that is, based on the ratio of A to B. 41. For example, when the pulling force reaches 50% (inclusive) to 100% (inclusive) of the pushing force, the pushing cylinder 421 is in a contracted state, the locking block 422 is away from the gear 41, and the piston rods of the first piston cylinder 31 and the second piston cylinder 32 can move, thus enabling leg exercise movements. When the pulling force is less than 50% of the pushing force, the pushing cylinder 421 is in an extended state, the locking block 422 abuts against the gear 41, and the piston rods of the first piston cylinder 31 and the second piston cylinder 32 cannot move, thus preventing leg exercise movements. This ensures that rehabilitation personnel must exercise according to the set force application pattern to guarantee better exercise results.
[0046] See Figure 1 and Figure 2The first piston cylinder 31, the second piston cylinder 32, and the connecting pipe 33 are all mounted on the bracket 4. A slide rail 6 is provided below the bracket 4. The bracket 4 is connected to the slide rail 6 and can slide along the slide rail 6 to move closer to or further away from the seat unit 1, so as to realize the adjustment of the distance between the damping unit 3 and the seat unit 1, thereby adapting to rehabilitation personnel of different heights. In addition, multiple positioning holes are provided on the bracket 4 along the extension direction of the slide rail 6. The bracket 4 is provided with a limiting hole, and the limiting pin can pass through the limiting hole and be inserted into the positioning hole to fix the position of the damping unit 3.
[0047] The regulating valve 34 can be a ball valve, allowing the flow area to be changed by rotating the ball valve, thereby adjusting the damping intensity. The regulating valve 34 can also be an electro-hydraulic proportional valve, electrically connected to the controller for control. Furthermore, a wireless receiving unit can be added to the controller to control the regulating valve 34, allowing rehabilitation personnel to adjust the damping intensity themselves. In addition, the seat unit 1 includes a pair of armrests 11 to help rehabilitation personnel maintain their balance.
[0048] Based on the above technical solution, the second aspect of this application provides a method for using a rehabilitation foot pedal 2 structure, comprising the following steps:
[0049] Damping force adjustment steps: Adjust the regulating valve 34 to obtain a suitable damping strength;
[0050] Foot binding procedure: Use strap 21 to bind the rehabilitation participant's feet to pedal 2;
[0051] Exercise steps: The rehabilitation personnel exert force with both legs simultaneously, so that when the left leg applies a pushing force to the first piston cylinder 31, the right leg applies a pulling force to the second piston cylinder 32, or when the left leg applies a pulling force to the first piston cylinder 31, the right leg applies a pushing force to the second piston cylinder 32.
[0052] By strapping the rehabilitation participant's feet to pedal 2, it becomes easier for them to apply pulling force to pedal 2. When pushing against pedal 2, the thigh muscles contract and the hamstring muscles relax; conversely, when pulling against pedal 2, the thigh muscles relax and the hamstring muscles contract. This ensures that both the thigh muscles achieve adequate relaxation, resulting in a more effective workout.
[0053] Furthermore, during the exercise, each pressure sensor 7 can detect the pushing or pulling force applied by the rehabilitation participant's legs to the first piston cylinder 31 and the second piston cylinder 32. When the ratio of the pulling force to the pushing force is within a set range, the controller controls the push cylinder 421 to move the locking block 422 away from the gear 41. Conversely, when the ratio of the pulling force to the pushing force is outside the set range, the controller controls the push cylinder 421 to move the locking block 422 into contact with the gear 41. For example, when the pulling force reaches 50% (inclusive) to 100% (inclusive) of the pushing force, the push... When cylinder 421 is in the retracted state, locking block 422 is away from gear 41, and the piston rods of the first piston cylinder 31 and the second piston cylinder 32 can move, thus enabling leg exercise movements. When the pulling force is less than 50% of the pushing force, pushing cylinder 421 is in the extended state, locking block 422 abuts against gear 41, and the piston rods of the first piston cylinder 31 and the second piston cylinder 32 cannot move, thus preventing leg exercise movements. This ensures that rehabilitation personnel must exercise according to the set force application pattern to achieve better training results.
[0054] The working principle of the rehabilitation foot pedal 2 structure in this application is as follows:
[0055] First, performing leg exercises in a seated position can effectively reduce the burden on the legs due to body weight, making it suitable for low-intensity leg exercises. Compared to bicycle-style rehabilitation equipment, placing the first piston cylinder 31 and the second piston cylinder 32 on the same plane as the seat cushion of the seat unit 1 allows the rehabilitation personnel to still have a relatively large range of flexion and extension when stepping on the pedals 2 of the first piston cylinder 31 and the second piston cylinder 32 in a seated position. This allows the rehabilitation personnel's ankle joints, knee joints, and even hip joints to be effectively moved and exercised.
[0056] In addition, strapping the rehabilitation participant's feet to the pedal 2 makes it easier for the participant to apply pulling force to the pedal 2. When the participant applies pushing force to the pedal 2, the quadriceps femoris muscle group in their legs contracts and the hamstring muscles relax. When the participant applies pulling force to the pedal 2, the quadriceps femoris muscle group relaxes and the hamstring muscles contract. This allows both the quadriceps femoris and hamstring muscles to be well relaxed, resulting in better training effects.
[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
