Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training equipment, and particularly relates to an ankle joint rehabilitation training device. Background Art

[0002] The ankle joint, also known as the talocrural joint, has a delicate structure and complex functions. It is a composite joint composed of the tibia, fibula, and trochlea of the talus, and can rotate and flex in different directions.

[0003] For patients with neurological lesions / degenerative diseases, the ankle strategy weakens, and the receptors in the joint cannot transmit correct joint position and movement information. As a result, the human body cannot activate the pontoreticular fiber bundle to make expected postural adjustments to the core muscles and perform normal ankle joint functional activities.

[0004] The rehabilitation exercises for the ankle joint include adduction / abduction, inversion / eversion, and dorsiflexion / plantar flexion. Long-term active and passive rehabilitation exercise interventions can achieve positive rehabilitation effects.

[0005] However, the development of ankle joint rehabilitation training institutions in China started relatively late, and the current design and research of rehabilitation devices do not accurately focus on a certain part. Most of them are only divided into upper limb and lower limb training devices, mainly manual single-movement training devices. For example, the Chinese utility model patent with the publication number CN207044201U discloses "a three-degree-of-freedom ankle joint device for exoskeleton robots", which is an ankle joint training device for the lower limb, and the device does not accurately focus on the ankle part. Moreover, in the current ankle joint rehabilitation devices, patients rely more on self-training, the training effect is poor, and it is easy for patients to be injured again due to unreasonable training. The above are the deficiencies of the prior art. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an ankle joint rehabilitation exercise training device that can achieve three rehabilitation exercise trainings of adduction / abduction, inversion / eversion, and dorsiflexion / plantar flexion, which is beneficial to improving the rehabilitation exercise training effect of the ankle joint.

[0007] The technical solution adopted by the utility model to solve its technical problem is as follows:

[0008] An ankle joint rehabilitation exercise training device includes an external structure frame and an internal movement structure.

[0009] (1) In the external structure frame, it includes a lower connecting plate, an upper connecting plate, a first pillar, a second pillar, a third pillar, and a fourth pillar. The lower connecting plate is connected to the first / second / third / fourth columns by screws to form a lower external frame; the upper connecting plate is connected to the first / second / third / fourth columns by screws to form an upper external frame.

[0010] (2) In the internal movement structure, it includes a leg fixing component, four sets of motor control components, and a foot support component.

[0011] In the leg fixing component, it includes a leg wrapper and six sets of connecting frames. The six sets of connecting frames are divided into three sets of left connecting frames and three sets of right connecting frames.

[0012] Further, the three sets of left connecting frames are installed on the first upright column by screws, and the three sets of right connecting frames are installed on the second upright column by screws.

[0013] In the four sets of motor control components, it includes a first motor control component, a second motor control component, a third motor control component, and a fourth motor control component.

[0014] Further, the first motor control component includes a first fixing block, a first motor, and a first telescopic rod. The first fixing block is near the first upright column, and the first fixing block is installed at the upper connecting plate by screws. The first motor is connected to the first fixing block and the first telescopic rod, and the first motor controls the movement of the first telescopic rod.

[0015] Further, the second motor control component, the third motor control component, and the fourth motor control component are respectively close to the second upright column, the third upright column, and the fourth upright column, and the remaining structures are all similar to those of the first motor control component.

[0016] In the foot support component, the foot support component includes a U-shaped connecting block, a C-shaped connecting block, a first lifting pillar, a second lifting pillar, a sole pedal, and a foot restraint strap.

[0017] Further, the second lifting pillar is connected to the lower connecting plate by screws and is connected to the U-shaped connecting block. The second lifting pillar controls the height of the U-shaped connecting block, thereby further controlling the height of the foot support component.

[0018] Further, the upper end of the U-shaped connecting block is connected to the front section of the C-shaped connecting block by screws, and the groove of the U-shaped connecting block is connected to the first lifting pillar.

[0019] Further, the rear end of the sole pedal is connected to the C-shaped connecting block by screws. A groove that can fit with the first lifting pillar is provided at the bottom end of the sole pedal, and the foot restraint strap is installed on the sole pedal by screws.

[0020] Further, a first spherical joint, a second spherical joint, a third spherical joint and a fourth spherical joint are installed on the sole pedal through screws. The first spherical joint is in spherical connection with the first telescopic rod, and this connection relationship enables the telescopic rod to determine the posture and position of the sole pedal.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] (1) The precise training part of the ankle joint rehabilitation exercise training device of the present utility model is assisted by the telescopic rod controlled by the motor, and the sole pedal is controlled through spherical connection, so as to realize three rehabilitation training methods of adduction / abduction, inversion / eversion, and dorsiflexion / plantar flexion.

[0023] (2) By controlling the spatial movement mode of the sole pedal, the risk of unnecessary injuries that may be caused by self-training is reduced, the safety in the rehabilitation training is improved, and a leg wrapping body and a foot restraint band are additionally designed, which improves the comfort during use while improving the safety.
