Description

Technical Field

[0001] This invention relates to the technical field of training devices, and in particular to a rehabilitation training device for upper and lower limb strength. Background Technology

[0002] As society progresses and people's living standards rise, so too does the pressure on many. Many people are experiencing sub-health conditions, such as fatigue and weakness, leading to decreased bodily functions and significant inconvenience. Consequently, more and more people are using indoor fitness equipment for exercise.

[0003] Currently, fitness equipment is divided into equipment for exercising the upper limbs and equipment for exercising the lower limbs. After exercising the upper limbs on one piece of equipment, users need to move to another piece of equipment to exercise the lower limbs, which is quite cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an upper and lower limb strength rehabilitation training device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this invention is:

[0006] A rehabilitation training device for upper and lower limb strength, having mutually orthogonal up-down, left-right, and front-back directions, includes: a frame; a chair component slidably connected to the frame in the front-back direction; a pull rod detachably snapped into the chair component; and a resistance mechanism disposed on the front side of the frame, wherein the pull rod is connected to the resistance mechanism via a resistance connector, and the resistance mechanism provides resistance to the pull rod.

[0007] Adjust the resistance mechanism as needed to match the user's target resistance value. During actual training, the user can sit or lie on the chair with their feet on the frame. When the user needs to exercise the upper limbs, remove the lever from the chair back and grasp it with both hands. When the user needs to exercise the lower limbs, attach the lever to the chair back and use the lower limbs to slide the chair back on the frame. In other words, on the same device, the user can exercise either the upper or lower limbs according to their needs, providing a good rehabilitation training experience.

[0008] As a further improvement to the above technical solution, a foot pedal mechanism connected to the frame is also included, the foot pedal mechanism including a pedal connected to the frame.

[0009] The addition of a foot pedal mechanism allows users to place their feet directly on the pedal, limiting the support position of their feet and reducing the likelihood of slipping during rehabilitation training.

[0010] As a further improvement to the above technical solution, the pedal is rotatably connected to the frame, and the rotation axis of the pedal is set in the left-right direction.

[0011] Because users have different heights and body types, the rotation angle of the pedal can be changed as needed to adapt the position of the pedal to the support position of the feet, thereby improving the user's rehabilitation training experience.

[0012] As a further improvement to the above technical solution, the foot pedal mechanism also includes a foot pedal drive component connected to the frame, the foot pedal drive component being used to change the rotation angle of the pedal.

[0013] Due to the differences in users' height and body shape, the foot pedal drive can be activated as needed to change the rotation angle of the pedal, thereby adapting the position of the pedal to the support position of the feet, thus improving the user's rehabilitation training experience. Moreover, the above adjustment method is relatively convenient.

[0014] As a further improvement to the above technical solution, the foot pedal drive component includes: a foot pedal frame rotatably connected to the frame, the foot pedal frame being rotatably connected to the bottom of the pedal, and the rotation axis of the foot pedal frame being arranged in the left-right direction; a rack, one end of which is rotatably connected to the pedal, and the rotation axis of the rack being arranged in the left-right direction; a gear meshing with the rack; and a foot pedal drive motor connected to the frame, the foot pedal drive motor driving the gear to rotate, and the rotation axis of the gear being arranged in the front-back direction.

[0015] The foot pedal drive motor rotates the gears, which in turn rotate the foot pedal frame through the transmission of the gears and rack, thereby changing the rotation angle of the pedals and adapting the position of the pedals to the support position of the feet, thus improving the user's rehabilitation training experience.

[0016] As a further improvement to the above technical solution, it also includes: a trolley, which is slidably connected to the frame in the front-back direction, the resistance mechanism being connected to the trolley, and a locking element being provided between the trolley and the frame; an adjusting plate, through which the chair component is connected to the frame, the chair component being slidably connected to the adjusting plate in the front-back direction, the front side of the adjusting plate being rotatably connected to the trolley, and the rotation axis of the adjusting plate being arranged in the left-right direction; and an adjusting mechanism, which is connected to the frame, and the adjusting mechanism is used to change the size of the angle between the adjusting plate and the horizontal plane.

[0017] The drive adjustment mechanism changes the angle between the adjustment plate and the horizontal plane. When the adjustment plate moves, the trolley adapts to the changed position of the adjustment plate to ensure that the adjustment plate can move normally. Simultaneously, the angle of the chair back connected to the adjustment plate will change so that the changed angle meets the user's needs, thereby improving the user's rehabilitation training experience. After the angle of the adjustment plate is adjusted, the locking part is locked again to limit the relative position of the trolley and the frame.

[0018] As a further improvement to the above technical solution, the adjustment mechanism includes: an adjustment drive member connected to the frame; and an adjustment connector having an adjustment connection end connected to the rear side of the adjustment plate. The adjustment drive member drives the adjustment connector to move, and causes the adjustment connection end to move in the up-down direction.

[0019] The adjustment drive unit drives the adjustment connector to move, which in turn causes the adjustment connector to move up and down. At this time, the adjustment plate rotates around the trolley, and the trolley moves to the target position synchronously, so that the angle adjustment changes to meet the user's needs, thereby improving the user's rehabilitation training experience. After the angle adjustment of the adjustment plate is completed, the locking part is locked again to limit the relative position of the trolley and the frame.

[0020] As a further improvement to the above technical solution, the adjustment mechanism further includes: an optical axis connected to the frame in a vertical direction; a linear bearing connected to the outer wall of the optical axis, the linear bearing being connected to the adjustment connector, the adjustment connector being rotatably connected to the adjustment plate, and the rotation axis of the adjustment connector being set in the left-right direction.

[0021] When the adjusting connector moves, it will synchronously drive the linear bearing to move. Since the optical axis and the linear bearing are compatible, the optical axis can limit the movement path of the linear bearing, and synchronously limit the movement path of the adjusting connector, so that the adjusting connector can move along the target path.

[0022] As a further improvement to the above technical solution, the resistance mechanism includes: a resistance motor connected to the frame; a resistance wheel driven by the resistance motor to rotate, the rotation axis of the resistance wheel being arranged in the left-right direction; one end of the resistance connector being connected to the pull rod, and the other end of the resistance connector being connected to the resistance wheel.

[0023] Adjust the output value of the resistance motor. The resistance motor transmits resistance through the static friction generated between the resistance wheel and the resistance connector.

[0024] As a further improvement to the above technical solution, the resistance mechanism further includes: a resistance frame connected to the frame and located between the rear sides of the resistance wheels; an upper pulley connected to the resistance frame and located above the resistance wheels, with the other end of the resistance connector passing through the upper pulley.

[0025] By adding a resistance frame and an upper pulley, and because the upper pulley is higher than the resistance wheel, the contact area between the resistance connector and the resistance mechanism is increased, allowing the resistance connector to transmit force in a certain direction.

[0026] As a further improvement to the above technical solution, the chair component includes: a chair frame that is slidably connected to the frame in the front-to-back direction, and the pull rod that is detachably snapped into the chair frame; shoulder pads that are spaced apart in the left-to-right direction and are connected to the chair frame, with the two shoulder pads located on the rear side of the seat cushion.

[0027] Since the chair frame allows users to sit or lie down, when users need to train while lying down, they can lie back on the chair frame with their shoulders against the two shoulder pads and their neck between the two shoulder pads. Attached Figure Description

[0037] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Furthermore, all connections / linkages mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0038] Reference Figures 1 to 7 This is a specific embodiment of the upper and lower limb strength rehabilitation training device of the present invention.

[0039] A rehabilitation training device for upper and lower limb strength has mutually orthogonal front-back, up-down and left-right directions, wherein the up-down direction is the direction of gravity.

[0040] A rehabilitation training device for upper and lower limb strength includes a frame 1, a chair 2, a pull rod 3, and a resistance mechanism 4.

[0041] In this embodiment, the chair 2 is connected to the frame 1, and the chair 2 is slidably connected to the frame 1. The sliding direction of the chair 2 is set along the front-back direction.

[0042] In this embodiment, the pull rod 3 is connected to the backrest component 2, and the pull rod 3 is close to the front side of the backrest component 2. The pull rod 3 and the backrest component 2 are detachably connected. Specifically, the pull rod 3 is horn-shaped.

[0043] In this embodiment, the resistance mechanism 4 is connected to the frame 1 and is located on the front side of the frame 1. A resistance connector 41 is connected between the pull rod 3 and the resistance mechanism 4. The material of the resistance connector 41 is an elastic material, and the resistance mechanism 4 provides resistance to the pull rod 3.

[0044] Adjust the resistance mechanism 4 as needed to match the user's target resistance value. During actual training, the user can sit or lie on the chair mechanism with their feet on the frame 1. When the user needs to exercise the upper limbs, remove the lever 3 from the backrest 2 and grasp the lever 3 with both hands. When the user needs to exercise the lower limbs, attach the lever 3 to the backrest 2 and use the lower limbs to slide the backrest 2 on the frame 1. In other words, on the same device, the user can exercise either the upper or lower limbs according to their needs, providing a good rehabilitation training experience.

[0045] Furthermore, it also includes a foot pedal mechanism 5, which is connected to the frame 1. The foot pedal mechanism 5 includes two pedals 51, both of which are connected to the frame 1. Specifically, the foot pedal mechanism 5 is located between the resistance mechanism 4 and the chair component 2.

[0046] By adding a foot pedal mechanism 5, the user's feet can be directly supported on the two pedals 51. The two pedals 51 limit the support position of the feet, reducing the chance of slipping during rehabilitation training.

[0047] Furthermore, both pedals 51 are rotatably connected to the frame 1, and the rotation axes of the two pedals 51 are parallel to the left and right directions. Specifically, both pedals 51 are recessed in a certain direction so that the user's two feet respectively abut against the two pedals 51.

[0048] Furthermore, the pedal 51 mechanism also includes a foot pedal drive 52, which is connected to the frame 1. The foot pedal drive 52 drives the two pedals 51 to rotate and changes the rotation angle of the two pedals 51. Specifically, the foot pedal drive 52 is located between the resistance mechanism 4 and the chair 2.

[0049] Due to the differences in users' height and body shape, the foot pedal drive component 52 is driven as needed to change the rotation angle of the two pedals 51, thereby adapting the position of the two pedals 51 to the support position of the feet, thus improving the user's rehabilitation training experience.

[0050] Furthermore, the foot drive component 52 includes a footrest 521, a rack 522, a gear 523, and a foot drive motor 524.

[0051] Specifically, the footrest 521 and the frame 1 are rotatably connected, and the rear side of the footrest 521 is connected to the frame 1. Both pedals 51 are connected to the footrest 521, and the bottom of the two pedals 51 is connected to the top of the footrest 521. The rotation axis of the footrest 521 is parallel to the left and right direction.

[0052] Specifically, there are two racks 522, the tops of which are rotatably connected to the bottoms of the two pedals 51 respectively. The rotation axes of the two racks 522 are set in the left and right direction, and a horizontal bar is connected between the two racks 522.

[0053] Specifically, gear 523 meshes with rack 522.

[0054] Specifically, the foot drive motor 524 is connected to the frame 1. The foot drive motor 524 drives the gear 523 to rotate and causes the gear 523 to rotate along the axis in the front-back direction. Specifically, both the gear 523 and the foot drive motor 524 are located to the side and below the foot drive motor 524.

[0055] The foot pedal drive motor 524 drives the gear 523 to rotate. Under the transmission of the gear 523 and the rack 522, the foot pedal frame 521 rotates, thereby changing the rotation angle of the two pedals 51 and adapting the position of the two pedals 51 to the support position of the two feet, thereby improving the user's rehabilitation training experience.

[0056] Furthermore, it also includes a trolley 6, an adjustment mechanism 8, and an adjustment plate 7.

[0057] Specifically, the trolley 6 is connected to the frame 1, and the trolley 6 and the frame 1 are slidably connected. The sliding direction of the trolley 6 is set in the front-back direction. The resistance mechanism 4 is connected to the trolley 6. Specifically, the foot pedal mechanism 5 is also connected to the trolley 6.

[0058] Specifically, the frame 1 is provided with a slide rail 11 for the trolley 6 to slide, so that the trolley 6 cannot derail from the frame 1. That is, the slide rail 11 can limit the forward, backward, up and down, and left and right movement positions of the trolley 6.

[0059] Specifically, a locking element 12 is connected between the frame 1 and the trolley 6. The locking element 12 and the frame 1 are detachably connected. The locking element 12 locks the trolley 6 so that it cannot slide backward. The locking element 12 can also be a bolt connected between the trolley 6 and the frame 1.

[0060] Specifically, the chair back piece 2 is slidably connected to the top of the adjustment plate 7 in the front-to-back direction, and the chair back piece 2 is connected to the frame 1 through the adjustment plate 7.

[0061] Specifically, the front side of the adjusting plate 7 is rotatably connected to the trolley 6, and the rotation axis of the adjusting plate 7 is parallel to the left and right direction.

[0062] Specifically, the adjustment mechanism 8 is connected to the frame 1, and the adjustment mechanism 8 drives the adjustment plate 7 to rotate, thereby changing the size of the angle between the adjustment plate 7 and the horizontal plane.

[0063] The drive adjustment mechanism 8 changes the angle between the adjustment plate 7 and the horizontal plane. When the adjustment plate 7 moves, the trolley 6 adapts to the changed position of the adjustment plate 7 to ensure that the adjustment plate 7 can move normally. Simultaneously, the angle of the chair back 2, which is slidably connected to the adjustment plate 7, will change so that the changed angle meets the user's needs, thereby improving the user's rehabilitation training experience. After the angle of the adjustment plate 7 is adjusted, the locking part is locked again to limit the relative position of the trolley 6 and the frame 1.

[0064] Furthermore, the adjustment mechanism 8 includes an adjustment connector 82 and an adjustment drive 81.

[0065] Specifically, the adjustment drive component 81 is connected to the frame 1; the adjustment connection end 821 is located at one end of the adjustment connection component 82, and the adjustment connection end 821 is rotatably connected to the rear side of the adjustment plate 7. The adjustment drive component 81 drives the adjustment connection component 82 to move, and causes the adjustment connection end 821 to move in the up and down direction.

[0066] The adjustment drive 81 drives the adjustment connector 82 to move, thereby causing the adjustment connector 821 to move in the up and down direction. At this time, the adjustment plate 7 rotates around the trolley 6, and the trolley 6 moves to the target position synchronously, so that the angle adjustment changes to meet the user's needs, thereby improving the user's rehabilitation training experience. After the angle adjustment of the adjustment plate 7 is completed, the locking part is locked again to limit the relative position of the trolley 6 and the frame 1.

[0067] Specifically, the adjustment drive component 81 includes an adjustment frame 811, an adjustment drive motor 812, an adjustment pulley assembly 813, a vertical bearing seat 814, a sprocket 815, an adjustment shaft 816, a chain 817, and a counterweight 818. The adjustment frame 811 is connected to the frame 1. The adjustment drive motor 812 is connected to the rear side of the adjustment frame 811. The adjustment shaft 816 is connected to the top of the adjustment frame 811 via the vertical bearing seat 814, and extends in the left-right direction. The adjustment drive motor 812 is connected to the adjustment shaft 816 via the adjustment pulley assembly 813. The sprocket 815 is connected to the outer wall of the adjustment shaft 816. The chain 817 meshes with the sprocket 815, and both ends of the chain 817 are connected to the counterweight 818 and the adjustment connector 82, respectively. The counterweight 818 is located behind the adjustment connector 82, which is a block structure.

[0068] Furthermore, the adjustment mechanism 8 also includes an optical axis 83 and a linear bearing 84; the optical axis 83 is arranged vertically and is connected to the frame 1. Specifically, the optical axis 83 is connected to the adjustment frame 811 and passes through the adjustment connector 82; the linear bearing 84 is connected to the adjustment connector 82 and is sleeved on the outer wall of the optical axis 83; the adjustment connection end 821 and the adjustment plate 7 are rotatably connected, and the rotation axis of the adjustment connection end 821 is arranged in the left-right direction.

[0069] When the adjusting connector 82 moves, it will synchronously drive the linear bearing 84 to move. Since the optical axis 83 and the linear bearing 84 are compatible, the optical axis 83 can limit the movement path of the linear bearing 84, and synchronously limit the movement path of the adjusting connector 82, so that the adjusting connector 82 can move along the target path.

[0070] Furthermore, the resistance mechanism 4 includes a pulley block 44, a resistance motor 42, and a resistance wheel 43; the resistance motor 42 is connected to the frame 1; the resistance motor 42 is used to drive the resistance wheel 43 to rotate, and the rotation axis of the resistance wheel 43 is parallel to the left and right direction; the pulley block 44 is connected to the frame 1, and the pulley block 44 is located behind the resistance wheel 43. The two ends of the resistance connector 41 are respectively connected to the pull rod 3 and the resistance wheel 43, and the resistance connector 41 passes through the pulley block 44; specifically, the pulley block 44 includes two fixed pulleys arranged vertically.

[0071] Adjust the output value of the resistance motor 42. The resistance motor 42 transmits resistance through the static friction generated between the resistance wheel 43 and the resistance connector 41.

[0072] Furthermore, the resistance mechanism 4 also includes a resistance frame 45 and an upper pulley 46; the resistance frame 45 is connected to the frame 1 and is located between the pulley block 44 and the resistance wheel 43. Specifically, the top of the resistance frame 45 is higher than the top of the pulley block 44 and the top of the resistance frame 45 is higher than the top of the resistance wheel 43; the upper pulley 46 is connected to the resistance frame 45 and is located above the pulley block 44 and the resistance wheel 43. The resistance connector 41 passes through the upper pulley 46. Specifically, there are two upper pulleys 46 arranged in the vertical direction, and the resistance connector 41 passes through both upper pulleys 46. The lower upper pulley 46 is also higher than the top of the resistance wheel 43 and the top of the pulley block 44, and the upper pulley 46 is also a fixed pulley.

[0073] By adding a resistance frame 45 and an upper pulley 46, since the upper pulley 46 is higher than the resistance wheel 43, the contact area between the resistance connector 41 and the resistance mechanism 4 is increased, so that the resistance connector 41 transmits force along a certain direction.

[0074] Specifically, the resistance connector 41 includes a first connecting rope and a second connecting rope, which are connected to each other. A tension sensor is connected between the first and second connecting ropes. The end of the first connecting rope away from the second connecting rope is connected to the pull rod 3. The first connecting rope passes through the pulley block 44 and the upper pulley 46. The end of the second connecting rope away from the first connecting rope is connected to the resistance wheel 43, and the second connecting rope can be wound around the resistance wheel 43. The tension sensor can determine whether the provided tension is greater than the resistance and other friction forces set by the resistance motor 42.

[0075] Furthermore, a controller can be connected to the frame 1. The controller is electrically connected to the tension sensor, the resistance motor 42, the adjustment drive motor 812, and the foot drive motor 524. The controller can change the output value of the resistance motor 42. The resistance motor 42 transmits resistance through the static friction generated between the resistance connector 41 and the resistance wheel 43.

[0076] Furthermore, the chair component 2 includes a chair frame 21, a seat cushion 22, and shoulder pads 23; the chair frame 21 is slidably connected to the frame 1 in the front-back direction; the pull rod 3 and the chair frame 21 are snap-fitted together. Specifically, two hooks 24 are provided on the front side of the chair frame 21, and the two hooks 24 are spaced apart in the left-right direction. The pull rod 3 is hung on the two hooks 24, and there is a gap between the top of the two hooks 24 and the top of the chair frame 21, and the openings of the two hooks 24 face backward; the seat cushion 22 is connected to the chair frame 21 in the horizontal direction, and the seat cushion 22 is located on the top of the chair frame 21; two shoulder pads 23 are provided, and the two shoulder pads 23 are connected to the chair frame 21 in the left-right direction, and the two shoulder pads 23 are spaced apart, and the two shoulder pads 23 are located behind the seat cushion 22.

[0077] Since the chair 2 can be used for sitting or lying down, a corresponding seat cushion 22 is provided for users to sit and train. When users need to train while lying down, they can lie on the seat cushion 22 with their shoulders against the two shoulder pads 23 and their neck between the two shoulder pads 23.

[0078] Furthermore, the relative positions of the seat cushion 22 and the backrest frame 21 in the front-to-back direction are adjustable and can be locked by bolts.

[0079] When using the upper and lower limb strength rehabilitation training device of the present invention, the adjustment drive 81 is driven as needed, which in turn drives the adjustment connector 82 to move in the up and down direction, causing the adjustment plate 7 to rotate, thereby changing the angle between the adjustment plate 7 and the horizontal plane.

[0080] Adjust the foot pedal drive motor 524 as needed to change the rotation angle of the two pedals 51 under the transmission of gear 523 and rack 522.

[0081] Users can choose to sit or lie on the seat cushion 22 with their feet pressed on the two pedals 51.

[0082] When it is necessary to exercise the upper limbs, remove the lever 3 from the hook 24; when it is necessary to exercise the lower limbs, attach the lever 3 to the hook 24.

[0083] Finally, by adjusting the resistance motor 42, the resistance of the pull rod 3 is changed in cooperation with the upper pulley 46, the pulley block 44 and the resistance wheel 43, allowing the user to exercise on the device.

[0084] In actual training, users can sit or lie on the chair mechanism with their feet supported on the frame 1. When they need to exercise their upper limbs, they can remove the lever 3 from the chair back 2 and grasp the lever 3 with both hands. When they need to exercise their lower limbs, they can attach the lever 3 to the chair back 2 and use their lower limbs to make the chair back 2 slide on the frame 1. In other words, on the same device, users can exercise their upper or lower limbs according to their needs, providing them with a good rehabilitation training experience.
