Description

Technical Field

[0001] The present invention relates to the technical field of lower limb recovery training, and in particular to a rehabilitation training device for lower limb recovery. Background Art

[0002] There are two main types of mature and common lower limb rehabilitation training devices on the market that can be used during bed rest and long-term bed rest periods. One is a bicycle-type lower limb bedside rehabilitation machine, which can simultaneously drive the feet, calves and thighs for exercise training and is the most widespread and popular. The other is a robotic arm-type lower limb rehabilitation training machine, which can drive a single leg for flexible and diverse exercise training, but is relatively more expensive and is not as widely used as a bicycle-type lower limb bedside rehabilitation machine.

[0003] Taking the bicycle-type lower limb bedside rehabilitation machine as an example, the bicycle-type lower limb bedside rehabilitation machine in the existing technology generally has the function of moving the whole machine, and at the same time has the function of height adjustment and telescopic propulsion footrest. It can flexibly and conveniently adapt to the use of patients in different positions. In terms of training, it has the ability to sense and judge the patient's muscle strength function, as well as active exercise, assisted exercise, passive exercise and other auxiliary training modes. Due to its flexibility and convenience, it has received relatively good market response.

[0004] Although this bicycle-style lower limb bedside rehabilitation machine can simultaneously drive the feet, calves and thighs for exercise training during cycling, in long-term application, the training is still relatively simple. The patient's lower limbs can only repeat a single pedaling action, and the trained muscles and muscle groups are relatively fixed. It has no training effect on ligaments and flexibility, and has certain limitations on comprehensive rehabilitation training of the lower limbs. Patients with a single form of exercise are also prone to boredom and tiredness. Summary of the Invention

[0022] 1. In the present invention, when the two foot boxes are installed on the pedal training mechanism, bicycle-type training exercises can be performed.

[0023] 2. In the present invention, when the two foot boxes are removed from the pedal training mechanism and the auxiliary training mechanism as a whole is in a vertical installation state on the pedal training mechanism, the two foot boxes can be installed on the two sliders on the two arc-shaped side rails, or on the two sliders on the arc-shaped middle rails.

The driving mechanism can assist the sliders on the arc-shaped side rails to slide on the arc-shaped side rails, and the driving member can also drive the sliders on the arc-shaped middle rails to slide on the arc-shaped middle rails with the help of the driving mechanism, thereby assisting the patient's legs to perform horizontal training movements.

[0025] 4. In the present invention, when the patient's legs perform vertical training exercises, and when the patient's legs perform horizontal training exercises, the legs are also stretched, which can assist in the training of the patient's ligaments and flexibility.

[0026] Therefore, the present invention not only has diverse training methods and trains a rich variety of muscles and muscle groups, but also combines ligament and flexibility training, which is beneficial to comprehensive rehabilitation training for lower limb recovery and has relatively few limitations.

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 10 As shown, this embodiment proposes a rehabilitation training device for lower limb recovery, including a body 1, a pedal training mechanism 4 is provided on the body 1, the body 1 has a moving function, a lifting mechanism 2 is provided on the body 1, the lifting mechanism 2 is connected to the telescopic propulsion mechanism 3, the pedal training mechanism 4 is connected to the telescopic propulsion mechanism 3, so that the pedal training mechanism 4 has a height lifting and adjusting function, as well as a telescopic propulsion function, two foot boxes 5 are detachably installed on the pedal training mechanism 4, the body 1, the lifting mechanism 2, the telescopic propulsion mechanism 3, the pedal training mechanism 4 and the foot box 5 are all well-known structures of the existing bicycle-type lower limb bedside rehabilitation machine, and will not be repeated here.

[0042] It should be noted that in the existing bicycle-type lower limb bedside rehabilitation machine, the two foot boxes 5 are fixedly connected to the pedal training mechanism 4. In the present invention, the two foot boxes 5 are detachably connected to the pedal training mechanism 4, for example, by bolts.

[0043] The present invention further comprises an auxiliary training mechanism, which is detachably mounted on the pedal training mechanism 4 and has two mounting states on the pedal training mechanism 4: horizontal and vertical.

[0044] Among them, the auxiliary training mechanism includes an arc-shaped middle slide rail 6 and two arc-shaped side slide rails 7, a slider 8, a driving mechanism and a connecting plate 13. Specifically, the arc-shaped middle slide rail 6 is fixedly connected between the two arc-shaped side slide rails 7, and the sliding direction of the arc-shaped middle slide rail 6 is consistent with that of the two arc-shaped side slide rails 7. The arc-shaped middle slide rail 6 and the arc-shaped side slide rail 7 are fixedly connected to two side plates 9 on the side facing the pedal training mechanism 4.

[0045] In order to assist the detachable installation of the training mechanism and the pedal training mechanism 4, the six side panels 9 are connected to a connecting frame 201, and two screws 202 are symmetrically connected to the connecting frame 201 on the side facing the pedal training mechanism 4. An assembly seat 203 is fixedly connected to the pedal training mechanism 4, and four through holes 204 are opened on the assembly seat 203 in a rectangular shape, and a nut 205 is threadedly connected to the screw 202.

[0046] When the arc-shaped middle slide rail 6 and the two arc-shaped side slide rails 7 are perpendicular to the bed surface, the two screws 202 can be inserted into the two opposite through holes 204 on the assembly seat 203, and the nuts 205 can be threadedly connected on the screws 202 to limit the screws 202 on the assembly seat 203, so that the auxiliary training mechanism as a whole is in a vertical installation state on the pedal training mechanism 4; when the arc-shaped middle slide rail 6 and the two arc-shaped side slide rails 7 are parallel to the bed surface, the two screws 202 can be inserted into the other two opposite through holes 204 on the assembly seat 203, and the nuts 205 can be threadedly connected on the screws 202 to limit the screws 202 on the assembly seat 203, so that the auxiliary training mechanism as a whole is in a horizontal installation state on the pedal training mechanism 4.

[0047] It should also be noted that, in order to facilitate the use of the auxiliary training mechanism, the assembly seat 203 can be set at the end of the pedal training mechanism 4 away from the telescopic propulsion mechanism 3, which is more convenient for the patient to use for training in bed. At the same time, in order to store the auxiliary training mechanism, a storage seat 206 is fixedly connected to the pedal training mechanism 4. The structure of the storage seat 206 is consistent with that of the assembly seat 203, so that the auxiliary training mechanism can be detachably installed on the storage seat 206 in the same way. The storage position of the assembly seat 203 can be set at a position that has no effect when the pedal training mechanism 4 performs bicycle-type training exercises.

[0048] A slider 8 is slidably installed on the arc-shaped side slide rail 7, and two sliders 8 are slidably installed on the arc-shaped middle slide rail 6. In order to separate the two sliders 8 on the arc-shaped middle slide rail 6, the arc-shaped middle slide rail 6 is divided into two sections. The slider 8 is detachably connected to the foot box 5. At the same time, the foot box 5 has two installation states on the slider 8, horizontal and vertical. The slider 8 is rotated toward one side of the pedal training mechanism 4 and is connected to the slide rod 10, and a sliding sleeve 11 is provided on the slide rod 10, and the sliding sleeve 11 is slidably installed between the two side panels 9.

[0049] In order to ensure the detachable connection between the slider 8 and the foot box 5, a mounting seat 101 is fixedly connected to the side of the slider 8 facing away from the pedal training mechanism 4. Four mounting heads 102 are connected to the mounting seat 101 in a rectangular shape. A connecting seat 103 is fixedly connected to the foot box 5. Two connecting heads 104 are symmetrically connected to the connecting seat 103. The mounting head 102 and the connecting head 104 are detachably connected by bolts.

[0050] When the auxiliary training mechanism as a whole is in a vertical installation state on the pedal training mechanism 4, the two foot boxes 5 can be vertically installed on the two sliders 8 on the two arc-shaped side slides 7, and the two connecting heads 104 correspond to the two opposite mounting heads 102 on the mounting seat 101, and the two mounting heads 102 are detachably connected to the two connecting heads 104 by bolts; when the auxiliary training mechanism as a whole is in a horizontal installation state on the pedal training mechanism 4, the two foot boxes 5 can remain vertically installed on the two sliders 8 on the arc-shaped middle slide 6, and the two connecting heads 104 correspond to the two opposite mounting heads 102 on the mounting seat 101, and the two mounting heads 102 are detachably connected to the two connecting heads 104 by bolts.

[0051] A driving mechanism is installed on the arc-shaped side slide 7, which is used to control the slider 8 to slide on the arc-shaped side slide 7. In a preferred embodiment, the driving mechanism is a telescopic electric cylinder 12, which is fixedly installed between the two side panels 9, and the output end of the telescopic electric cylinder 12 is fixedly connected to the sliding sleeve 11 of the arc-shaped side slide 7.

[0052] When the telescopic electric cylinder 12 is started, it can drive the sliding sleeve 11 between the two side plates 9 on the arc-shaped side slide 7 to slide between the two side plates 9. When the sliding sleeve 11 slides, it drives the sliding rod 10 to move along the sliding direction of the sliding sleeve 11. The sliding rod 10 synchronously drives the slider 8 to move along the sliding direction of the sliding sleeve 11. However, since the slider 8 slides in an arc on the arc-shaped side slide 7, when the slider 8 is driven by the sliding rod 10, it also drives the sliding rod 10 to slide in the sliding sleeve 11 along the length direction of the sliding sleeve 11. The arc-shaped movement of the slider 8 on the arc-shaped side slide 7 is achieved by the rotation of the slider 8 on the sliding rod 10.

[0053] A connecting plate 13 is detachably connected between the slider 8 on the arc-shaped middle slide rail 6 and the slider 8 on the arc-shaped side slide rail 7. In a preferred embodiment, the connecting plate 13 is fixedly connected to the sliding sleeve 11 of the arc-shaped middle slide rail 6, and the other side of the connecting plate 13 is detachably connected to the sliding sleeve 11 of the arc-shaped side slide rail 7 by bolts. When the connecting plate 13 is connected to the sliding sleeve 11 of the arc-shaped side slide rail 7 by bolts, the sliding sleeve 11 of the arc-shaped middle slide rail 6 can be driven by the sliding sleeve 11 of the arc-shaped side slide rail 7, so that the slider 8 on the arc-shaped middle slide rail 6 can be driven to slide on the arc-shaped middle slide rail 6 with the help of a driving mechanism, thereby assisting the patient's legs to perform lateral training exercises.

[0054] In this embodiment, when the two foot boxes 5 are installed on the pedal training mechanism 4 , the patient's feet can be placed in the two foot boxes 5 , so that the patient can perform bicycle-style training exercises on the bed through the pedal training mechanism 4 .

[0055] When the two foot boxes 5 are removed from the pedal training mechanism 4 and the auxiliary training mechanism as a whole is in a vertical installation state on the pedal training mechanism 4, the two foot boxes 5 can be installed on the two sliders 8 on the two arc-shaped side rails 7, or installed on the two sliders 8 on the arc-shaped middle rail 6. The patient can lie on the bed and perform vertical training exercises with his legs. The driving mechanism can assist the sliders 8 on the arc-shaped side rails 7 to slide on the arc-shaped side rails 7, and the driving member can also drive the sliders 8 on the arc-shaped middle rail 6 to slide on the arc-shaped middle rail 6 with the help of the driving mechanism, thereby assisting the patient's legs to perform vertical training exercises.

[0056] When the auxiliary training mechanism as a whole is in a horizontal installation state on the pedal training mechanism 4, the two foot boxes 5 can be installed on the two sliders 8 on the two arc-shaped side rails 7, or on the two sliders 8 on the arc-shaped middle rail 6. The patient can lie on the bed and perform horizontal training exercises with his legs. The driving mechanism can assist the sliders 8 on the arc-shaped side rails 7 to slide on the arc-shaped side rails 7, and the driving member can also drive the sliders 8 on the arc-shaped middle rail 6 to slide on the arc-shaped middle rail 6 with the help of the driving mechanism, thereby assisting the patient's legs to perform horizontal training exercises.

[0057] When the patient's legs perform vertical training exercises, and when the patient's legs perform horizontal training exercises, the legs are also stretched, which can assist in training the patient's ligaments and flexibility. At the same time, when the patient's feet are in the two shoe boxes and the two foot boxes 5 are not moving, the telescopic propulsion mechanism 3 can also drive the patient's lower limbs to be stretched.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
