DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem of how to make the rehabilitation training device adapt to the training intensity of patients in different recovery stages, the present invention provides an upper and lower limb adjustable rehabilitation training device. Since the resistance of the resistance component 300 is adjustable, it can adapt to the training intensity requirements of patients in different stages.

[0019] It should be noted that the adjustable upper and lower limb rehabilitation training device of the present invention is used for but not limited to rehabilitation training, etc. For the convenience of explanation, in the present invention, only the application of the adjustable upper and lower limb rehabilitation training device to rehabilitation training is used as an example for explanation. The principles of applying the adjustable upper and lower limb rehabilitation training device to other types of equipment are essentially the same as those applied to rehabilitation training, and will not be elaborated here.

[0020] See also Figure 1 , Figure 1 The structure diagram of the upper and lower limbs adjustable rehabilitation training device in one embodiment of the present invention comprises a base 100, an interactive component 200 and a resistance component 300. The interactive component 200 comprises a rotating handle 210 and a rotating pedal 220. Both the rotating handle 210 and the rotating pedal 220 are rotatably mounted on the base 100. The resistance component 300 is respectively connected to the rotating handle 210 and the rotating pedal 220 in a transmission manner, and has a resistance that hinders the rotation of the rotating handle 210 and the rotating pedal 220, and the resistance of the resistance component 300 is adjustable.

[0021] In this embodiment, the patient can grasp the rotating handle 210 with both hands, thereby driving the rotating pedal 220 to rotate. The patient can step on the rotating pedal 220 with both feet, thereby driving the rotating pedal 220 to rotate. The resistance component 300 has resistance that hinders the rotation of the rotating handle 210 and the rotating pedal 220. The patient drives the rotating handle 210 and the rotating pedal 220 to overcome the resistance, thereby exercising the upper and lower limbs. Since the resistance of the resistance component 300 is adjustable, it can meet the training intensity requirements of patients at different stages.

[0022] In some embodiments, the resistance assembly 300 includes a first cone roller 310, a second cone roller 320, a first transmission belt 330 and an adjusting member 340. The first cone roller 310 and the second cone roller 320 are parallel to each other and rotatably installed on the base 100, and the conical surfaces of the first cone roller 310 and the second cone roller 320 are arranged opposite to each other. The first transmission belt 330 surrounds the first cone roller 310 and the second cone roller 320. The adjusting member 340 can drive the first transmission belt 330 to move axially along the first cone roller 310 to adjust the transmission ratio between the first cone roller 310 and the second cone roller 320. The rotating handle 210 and the rotating pedal 220 are both transmission-connected to the first cone roller 310.

[0023] In this embodiment, the first transmission belt 330 is driven to move along the axial direction of the first tapered roller 310 by the adjusting member 340, so that the diameter of the first tapered roller 310 and the diameter of the second tapered roller 320 where the first transmission belt 330 surrounds can be changed, thereby changing the transmission ratio between the first tapered roller 310 and the second tapered roller 320, thereby playing a role in adjusting the resistance of the resistance assembly 300.

[0024] Any implementation of the adjusting member 340 that can drive the axial movement of the first transmission belt 330 and the first cone roller 310 is feasible. In some embodiments, the adjusting member 340 includes a linear motor 341 and a ring 342. The ring 342 is sleeved on the outer periphery of the first transmission belt 330, and the linear motor 341 drives the ring 342 to move axially along the first cone roller 310.

[0025] In this embodiment, the linear motor 341 can drive the collar 342 to slide, and the collar 342 can drag the first transmission belt 330 to move along the axial direction of the first tapered roller 310 .

[0026] In some of the embodiments, the interactive component 200 also includes a handle roller 230, a pedal roller 240 and a second transmission belt 250, the handle roller 230 is transmission connected to the rotating handle 210, the pedal roller 240 is transmission connected to the rotating pedal 220, and the second transmission belt 250 surrounds the handle roller 230 and the pedal roller 240.

[0027] In this embodiment, the handle roller 230 and the pedal roller 240 are connected to each other through the second transmission belt 250, and then the rotating handle 210 and the rotating pedal 220 are connected to each other.

[0028] In some embodiments, the inner side of the handle roller 230 has a plurality of first ratchet teeth 231, the rotating handle 210 has a first transmission portion 211 and a first elastic portion 212, the first elastic portion 212 is installed on the outer periphery of the first transmission portion 211, and the first elastic portion 212 has an elastic force to press the first ratchet teeth 231 to limit the handle roller 230 from rotating in a forward direction relative to the first transmission portion 211, and allow the handle roller 230 to rotate in a reverse direction relative to the first transmission portion 211.

[0029] In this embodiment, when the handle roller 230 rotates in the forward direction relative to the first transmission part 211, the first elastic part 212 will slide along the wedge surface of the first ratchet 231, so that the first elastic part 212 will not hinder the handle roller 230 from rotating in the forward direction relative to the first transmission part 211. When the handle 210 is rotated in the reverse direction relative to the first transmission part 211, the first elastic part 212 will clamp the first ratchet 231, so that the first elastic part 212 will hinder the handle roller 230 from rotating in the reverse direction relative to the first transmission part 211.

[0030] Therefore, when the patient wants to perform upper limb training, the first elastic part 212 blocks the handle roller 230, so that the two rotate synchronously, and the patient needs to overcome the resistance by rotating the handle 210 to achieve the effect of upper limb training. When the patient does not want to perform upper limb training, the first elastic part 212 does not block the handle roller 230 from rotating in the positive direction relative to the first transmission part 211, and the rotating handle 210 can remain stationary.

[0031] In some embodiments, the first elastic portion 212 includes a first flap 2121 and a first spring 2122, one end of the first flap 2121 is pivotally connected to the first transmission portion 211, and the two ends of the first spring 2122 are respectively connected to the first flap 2121 and the first transmission portion 211, and it has an elastic force that pushes the free end of the first flap 2121 to press against the first ratchet 231.

[0032] In this embodiment, when the handle roller 230 rotates relative to the first transmission part 211 in the forward direction, the wedge surface of the first ratchet 231 presses against the first flap 2121, and the first flap 2121 compresses the first spring 2122 and flips toward the direction close to the first elastic part 212, so that the first ratchet 231 can pass through the first transmission part 211. When the handle roller 230 rotates relative to the first transmission part 211 in the reverse direction, the first flap 2121 will clamp the first ratchet 231, thereby preventing the first ratchet 231 from passing through the first flap 2121.

[0033] In some embodiments, the inner side of the pedal roller 240 has a plurality of second ratchet teeth 241, the rotating pedal 220 has a second transmission portion 221 and a second elastic portion 222, the second elastic portion 222 is installed on the outer periphery of the second transmission portion 221, and the second elastic portion 222 has an elastic force to press the second ratchet teeth 241 to limit the pedal roller 240 from rotating in a forward direction relative to the second transmission portion 221, and allow the pedal roller 240 to rotate in a reverse direction relative to the second transmission portion 221.

[0034] In this embodiment, when the pedal roller 240 rotates in the forward direction relative to the second transmission part 221, the second elastic part 222 will slide along the wedge surface of the second ratchet 241, so that the second elastic part 222 will not hinder the pedal roller 240 from rotating in the forward direction relative to the second transmission part 221. When the rotating pedal 220 rotates in the reverse direction relative to the second transmission part 221, the second elastic part 222 will get stuck in the second ratchet 241, so that the second elastic part 222 will hinder the pedal roller 240 from rotating in the reverse direction relative to the second transmission part 221.

[0035] Therefore, when the patient wants to perform lower limb training, the second elastic part 222 blocks the pedal roller 240, so that the two rotate synchronously, and the patient needs to overcome the resistance by rotating the pedal 220 to achieve the effect of training the lower limbs. When the patient does not want to perform lower limb training, the second elastic part 222 does not block the pedal roller 240 from rotating in the positive direction relative to the second transmission part 221, and the rotating pedal 220 can remain stationary.

[0036] In some embodiments, the second elastic portion 222 includes a second flap 2221 and a second spring 2222, one end of the second flap 2221 is pivotally connected to the second transmission portion 221, and both ends of the second spring 2222 are respectively connected to the second flap 2221 and the second transmission portion 221, and has an elastic force that pushes the free end of the second flap 2221 to press against the second ratchet 241.

[0037] In this embodiment, when the pedal roller 240 rotates relative to the second transmission part 221 in the forward direction, the wedge surface of the second ratchet 241 presses against the second flap 2221, and the second flap 2221 compresses the second spring 2222 and flips toward the direction close to the second elastic part 222, so that the second ratchet 241 can pass through the second transmission part 221. When the pedal roller 240 rotates relative to the second transmission part 221 in the reverse direction, the second flap 2221 will clamp the second ratchet 241, thereby preventing the second ratchet 241 from passing through the second flap 2221.

[0038] In some embodiments, the interaction component 200 further includes a first gear 260 and a second gear 270, wherein the first gear 260 is coaxially fixed to the pedal roller 240, and the second gear 270 is coaxially fixed to the first cone roller 310, and the first gear 260 and the second gear 270 are meshed with each other.

[0039] In some embodiments, the resistance assembly 300 further includes a servo motor 350 , which is transmission-connected to the second cone roller 320 to drive the second cone roller 320 to rotate.

[0040] In this embodiment, the servo motor 350 can drive the second cone roller 320 to rotate. On the one hand, the servo motor 350 can reduce or increase the resistance of the resistance assembly 300, thereby changing the training intensity of the patient.

[0041] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the present invention is described in detail: The patient can grasp the rotating handle 210 with both hands, thereby driving the rotating pedal 220 to rotate. The patient can step on the rotating pedal 220 with both feet, thereby driving the rotating pedal 220 to rotate. The resistance assembly 300 has a resistance that hinders the rotation of the rotating handle 210 and the rotating pedal 220. The patient drives the rotating handle 210 and the rotating pedal 220 to overcome the resistance, thereby exercising the upper and lower limbs. The first transmission belt 330 is driven to move along the axial direction of the first cone roller 310 by the adjustment member 340, thereby changing the diameter of the first cone roller 310 and the diameter of the second cone roller 320 where the first transmission belt 330 surrounds. Then, the transmission ratio between the first cone roller 310 and the second cone roller 320 is changed, thereby adjusting the resistance of the resistance assembly 300. Since the resistance of the resistance assembly 300 is adjustable, it can meet the training intensity requirements of patients at different stages.

[0042] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
