Description

Method and device for generating equilibrium resistance

The invention relates to a method and a device for generating equilibrium resistance according to the magnitude of an applied force. Background technique

In competitive sports training, strength training is a very important training item. The theory of strength training believes that the stronger the muscles are, the better the training effect. The traditional training method is to use weights or springs and rubber. Gravity or elastic force such as bar is used as muscle load, but when the human body is doing training movements, due to the geometric leverage of the bones, the geometric position in the movement process is different, and the muscle strength is different, so they can only make the muscle load actually It is an average load. This average load may be suitable for a certain part of the training movement, but most of the links are small, so the muscle stimulation cannot reach the strongest intensity, which affects the training effect. However, For a link that exceeds the muscle's load capacity and causes overload, it is often at this link that sports trauma is caused. Object of the invention

In view of this, how can a method and device be provided that can generate balanced resistance so that when the human body performs physical exercises, the part of the human body exercise has always been in a state of extreme load, and according to the state of human movement, it can artificially adjust the effect on The strength-balance resistance on the human body, to achieve the best and most effective exercise effect, and to avoid sports trauma beyond the human limit, is exactly the motivation of the invention.

The method of the present invention is further characterized in that the movement of the object can be selected as a flexible winding wound on the reel, and the human body exercises a force directly or indirectly on the flexible winding, and the human body will feel a balanced resistance that tracks the force applied ; The actuator that controls the generation of balanced resistance is a magnetic powder brake. The speed detector detects the change in the rotation speed of the magnetic powder brake rotor to indirectly reflect the change in the magnitude of the external force, and feeds back the speed change signal to the magnetic powder after processing by the electrical control device Brake, thereby achieving balanced resistance training.

The balance resistance generating device of the present invention can be used for strength training of the human body. The balance resistance generating device shown in Figs. 1 to 4 is adopted, so that the force acting on the muscle is not a constant gravity or an elasticity that changes according to Hooke's law. Force; it is a training method that can automatically track changes in muscle dynamics and maintain balanced resistance at the same level at all times.

As shown in FIG. 1, the magnetic powder brake 1 controlled by the electric control device 6 is connected to the reel 3 through the one-way check mechanism 2, and the reel 3 is further connected to the energy storage reset mechanism 4. The reel 3 is wound with flexibility. The rope 5, the speed detector 7 are connected to the electric control device 6 and the magnetic powder brake 1. The electric control device 6 receives the speed signal of the reel 3 given by the speed detector 7, and amplifies and outputs the signal to the magnetic powder brake 1 to control the exciting current of the magnetic powder brake 1.

A power supply 12, a shaping amplifier 13, a signal output device 14, a screen display 15, a positive and negative identification device 16 and an absolute value taking device 17 are installed in the electric control device 6, each of which is an existing known component.

As shown in FIG. 5, the power source 12 is connected to the shaping amplifier 13 and the speed sensor 7 (existing components), the speed detector 7 is connected to the positive and negative identification device 16 and the absolute value device 17, and then connected to the shaping amplifier 13 to shape the One end of the amplifier 13 is connected to the magnetic powder brake 1, and the other end is connected to the screen display 15 through a signal output device 14.

When an external force is applied to the flexible rope 5, the reel 3 and the rotor of the magnetic powder brake 1 generate a rotational motion due to the action of the one-way check mechanism 2. At this time, the speed detector 7 converts this rotational motion into The electric signal is fed back to the electric control device 6. The electric control device 6 processes and amplifies the signal and outputs it to the excitation circuit of the magnetic powder brake 1. Provides an exciting current for the magnetic powder brake 1 to control the magnetic powder brake 1 to generate appropriate At the same time, the energy storage reset mechanism 4 also accumulates energy during the rotation. It is considered that when the external force for the flexible winding 5 changes, for example, when the external force is increased, the rotation speed of the rotor of the reel 3 and the magnetic powder brake 1 must be increased, and the speed signal detected by the speed detector 7 is also It will increase accordingly. After the amplified signal is amplified by the electric control device 6, the exciting current output to the magnetic powder brake 1 is also greatly increased, and the braking torque generated by the magnetic powder brake 1 is rapidly increased. It is impossible to force the rotation speed of the reel 3 to change significantly. On the contrary, when the external force applied to the flexible rope 5 is reduced, the braking torque of the magnetic powder brake 1 is correspondingly reduced to maintain the same. The movement speed is relatively stable, thus achieving the purpose of enabling the reaction force generated by the system to track the change of external force in time and maintain the state equal to the external force at all times. adaptability.

When the external force used for the flexible winding 5 disappears, because the energy storage type reset mechanism 4 has accumulated energy, and because of the action of the one-way check mechanism 2, the reel can be rotated in the reverse direction quickly without any obstacles. The flexible rope 5 is re-wound and restored to the initial state, so that the above-mentioned actions can be repeatedly performed repeatedly.

The working principle of Embodiment 2 is the same as that of Embodiment 1. When two or more external forces are required to act simultaneously or alternately, as shown in FIG. 2, due to the one-way check mechanisms 2 and 2 ′ This embodiment allows external force to act on any flexible rope 5 or 5 ′, and also allows two external forces to act on the flexible rope 5 or 5 ′ at the same time or alternately. Disturbances; the reel 3 'and the energy storage reset mechanism 4' are connected in the same way as the reel 3 and the energy storage reset mechanism 4 described above; by extending this solution, any number of external forces can be allowed to act simultaneously or alternately. And each external force does not interfere with each other, and each roll can be reset freely.

When the external force is not a linear motion but is a force couple, an example of the implementation is shown in FIG. 3. When the external force acts on the handle or the pedal 11 to generate a rotary motion, the magnetic powder is transmitted through the transmission wheel 10 and the transmission wheel 9. The brake rotates with it, and its working principle is the same as that of the embodiment 1. The function of the inertia wheel 8 is to eliminate dead points.

When the external force is not a linear motion but a friction force, an example of the embodiment is shown in FIG. 4, and the friction force acting as the external force is applied to the drum 12 ′, and its working principle is the same as the above embodiments.

In summary, it is a preferred embodiment of the present invention. Any change made according to the technical solution of the present invention that does not exceed the scope of the technical solution of the present invention belongs to the protection scope of the present invention.
