When the device is used for training, a patient wears the training shoes, firstly, the weight is weighed on the electronic weight scale, then the waist and the thighs of the patient are bound by the waist support and the binding belt, the weight reduction motor is started to enable the screw rod to face upwards, the balance suspension rod rotates around the pin shaft at this time to compress the balance spring and conduct the spring to the pressure sensor, the weight reduction value can be obtained according to signals obtained by the pressure sensor, and the patient can start training after the weight reduction value meets requirements. During training, the patient can hold the handrail guardrail by hands.

The design and training mechanism of the device is as follows: when people walk on the ground naturally, the static friction force generated by the sole and the ground drives the human body to generate displacement. Given the very small friction factor of the contact surfaces, it is only possible to glide and it is very difficult to ensure safety or to maintain balance. The spherical concave omnibearing running platform on the base adopts a Teflon coating with a certain friction factor, and the sole adopts the material structure to form a certain friction force, so that the real walking stress state of a person is simulated, and the person feels that the person walks on a normal road instead of sliding on a smooth ground. Normal friction is easier to keep balance, thus greatly shortening the learning process, and all people can easily learn to use the device. When a person walks on the flat ground, the legs circularly and alternately swing by taking the crotch joint as the axis, and the gravity of the human body is alternately exerted on the ground by the two feet at the same time. Therefore, the human body must be supported equally at the moment to ensure the stability of the human body, and the supporting force is finally directed to the center of mass of the human body. Therefore, the spherical concave omnibearing running platform manufactured when a person walks provides the supporting force pointing to the mass center. Thereby simulating the natural walking feeling to the maximum extent, which can greatly enhance the training effect. The platform is run to omnidirectional ball-type concave surface adopts the special low coefficient of friction shoes of teflon coating, and the special low coefficient of friction shoes of cooperation and gyro wheel money shoes can all carry out the omnidirectional and move, and the gyration piece is connected to the support column, can change the direction and carry out the omnidirectional and run, and the sole embedding low coefficient of friction material or put a wheel, no matter how so you walk, all can slide back in the platform is run to omnidirectional movement of spherical concave surface. The walking mode is a little like that the sole is too slippery when climbing uphill, and the walking is not slippery when walking, and the patient can pass through the waist binding system and the corresponding running table to cooperate with the training shoes, so that the waist binding system can reduce weight, and can directly train on the spherical concave sports running table. In the training process, the patient can support the guardrail in a hand to assist in training. The flexible supporting buffer device and the connecting block have better left-right torsion resistance.

Can support the patient of certain dynamics to the hand, can also hold handrail guardrail and subtract heavy, because the dynamics patient of hand guardrail can independently be adjusted, can subtract training under the weight change condition in the training in fact, this can further strengthen the training effect, at this moment plantar pressure sensor in the training shoes can be real reflects plantar pressure, it subtracts the weight value that the weight value of subtracting of mechanism can reach patient hand guardrail department to pull through this pressure and stereoplasm, because the upper limbs problem that often accompanies the correspondence of a lot of low limbs dysfunction, so still be favorable to understanding and aassessment the dynamics of patient hand through this device.

After the embodiments of the present invention have been described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above claims, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention all fall within the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments of the examples given in the specification.
