The output column is a cylindrical body which is protruded towards the direction of the input support on the output seat and is used for arranging the output support and the output shaft.

The magnetism of one end of the input magnetic block in the anticlockwise direction is the same as that of one end of the output magnetic block in the clockwise direction; the brake device also comprises a brake magnetic block 7 and a control panel 8; the output base 4 is also provided with four buffer magnetic blocks 42 and a Hall switch 43, the buffer magnetic blocks are arranged on the end surface of the output base facing the input base, the Hall switch is arranged in a switch hole on the output base, the buffer magnetic blocks are connected with the control panel through wires, and the Hall switch is also connected with the control panel 8 through wires; the braking magnetic block and the buffering magnetic block are both composed of an iron core and a coil.

The buffer magnetic block is arranged on a buffer magnetic block seat 44 on the end face of the output seat facing the input seat, a notch is formed in the edge of the buffer magnetic block seat, and a lead connecting the buffer magnetic block and the control board penetrates through the notch.

The distribution positions of the buffer magnetic blocks correspond to the distribution of the output magnetic blocks, when the projection of one output magnetic block is overlapped with one buffer magnetic block, the projections of the other three output magnetic blocks are also respectively overlapped with the corresponding buffer magnetic blocks.

And the coil of the braking magnetic block and the coil of the buffering magnetic block are respectively connected with the super capacitor in the control panel through leads.

The input bearing 11 adjacent the input carrier is a unidirectional bearing in the same direction as the output bearing 62.

When the engine drives the input shaft to rotate anticlockwise, the Hall switch is arranged on the output base between the second and third buffer magnetic blocks on the braking magnetic block in the anticlockwise direction.

The Hall switch is a magnetic induction type electronic switch using Hall effect, belongs to an active magnetoelectric conversion device, and is a common technology.

The distance from the input magnetic block to the input shaft is equal to the sum of the distance from the output magnetic block to the output shaft and the distance from the output shaft to the input shaft. When the brake magnetic block attracts one output magnetic block to make it unable to move, the input magnetic block rotating anticlockwise reaches the output magnetic block attracted by the brake magnetic block and then collides with the output magnetic block. In the invention, when the output magnetic block is attracted by the brake magnetic block, as long as the input magnetic block is close to the output magnetic block, the brake magnetic block loses magnetic force due to no electricity to release the output magnetic block, and because the input magnetic block and the output magnetic block are very close to each other, strong repulsive force is generated between the input magnetic block and the output magnetic block to push the output magnetic block to drive the output bracket to rotate quickly.

The motor drives the input bracket to synchronously rotate anticlockwise through the input shaft, then a repulsive force is generated when one end of the input magnetic block in the anticlockwise direction is close to the output magnetic block which is locked by the braking magnetic block and the buffering magnetic block and has the same magnetism in the rotating process, when one input magnetic block reaches the position closest to the output magnetic block attracted by the braking magnetic block, the braking magnetic block and the buffering magnetic block do not have attraction force on the output magnetic block any more because the power of the super capacitor is exhausted or the control board stops outputting power to the braking magnetic block and the buffering magnetic block, the repulsive force between the input magnetic block and the output magnetic block closest to the braking magnetic block is also maximized, the repulsive force pushes the output magnetic block and the output bracket fixedly connected with the output magnetic block to rotate anticlockwise, the rotating speed of the output bracket is higher than that of the input bracket, and the output bracket rotates anticlockwise to drive the output shaft meshed with the output bracket to rotate to output power.

When the output magnetic block on the output support rotates to the position above the braking magnetic block, the strong magnetic force of the braking magnetic block can enable the output support to stop rotating to achieve braking of the output support.

When the input magnetic block on the input bracket is close to the output magnetic block on the output bracket in limit, the brake magnetic block loses the suction force to the output magnetic block due to the fact that the electric energy of the super capacitor is exhausted or the super capacitor is controlled by the control board to stop supplying power to the brake magnetic block and the buffer magnetic block, so that the output bracket is released, and the output bracket is driven to rotate due to strong repulsive force generated between the input magnetic block and the output magnetic block.

When the output magnetic block on the output support passes through the braking magnetic block and the buffering magnetic block, electric energy is generated due to electromagnetic induction and stored in the super capacitor, the output magnetic block on the output support passes through the Hall switch every time, the Hall switch transmits a signal to the control panel, and the control panel transmits the electric energy of the super capacitor to the braking magnetic block and the buffering magnetic block to enable the braking magnetic block to generate magnetic force to realize braking of the output support.

The diameter of the output bracket is smaller than that of the input bracket, and when the input magnetic block runs to be close to the braking magnetic block, repulsive force can be generated between the input magnetic block and the output magnetic block attracted by the braking magnetic block. The output support rotational speed is greater than the input support and realizes the variable speed, and when the output support was driven to rotate, output shaft and output support rotate with the same speed and realize the output of power, even output support no longer rotates, the output shaft still can continue to rotate a period of time under the inertia.

The output support rotates faster than the input support in one moment, and rotates fast in the next moment, and the rotation amplitude is smaller than or equal to 90 degrees.

When the output bracket is driven to rotate quickly and then is braked by the buffer magnetic block and the brake magnetic block and then stops rotating, because the output bearing is a one-way bearing, the inner ring of the output bearing and the output shaft still continue to rotate anticlockwise under inertia, the continuity of power output is maintained, and only the speed is gradually reduced along with the time. When the input magnetic block on the input bracket is close to the output magnetic block attracted by the brake magnetic block, strong repulsive force is generated between the input magnetic block and the output magnetic block, and the output magnetic block is released after the magnetism of the brake magnetic block and the buffer magnetic block disappears, so that the output bracket rotates rapidly, the rotating speed of the output bearing outer ring driven by the output bracket is higher than that of the previous output bearing inner ring, and the speed of the output bearing inner ring is changed into the same speed as that of the output bracket.

In the application, the output support is assisted to decelerate through the buffering magnetic block, braking is achieved through the braking magnetic block, when the input magnetic block is very close to the output magnetic block attracted by the braking magnetic block, the braking magnetic block does not attract the output magnetic block any more, and therefore strong repulsive force can be generated to push the output support to rotate fast, and non-contact acceleration is achieved.

The buffer magnetic block and the brake magnetic block are electromagnetic blocks consisting of magnetic cores and coils, when the output magnetic block rotates to pass through the buffer magnetic block and the brake magnetic block, currents can be generated in the buffer magnetic block and the brake magnetic block, the currents are transmitted to the super capacitor in the control board through conducting wires to be stored, and when the Hall switch detects that the output magnetic block passes through, the control board is informed to enable the super capacitor to supply power to the buffer magnetic block and the brake magnetic block to enable the buffer magnetic block and the brake magnetic block to generate magnetism, so that the passing passive magnets can be attracted to achieve braking.

The above-mentioned embodiments are only used for illustrating the application of the present invention, and are not meant to be limiting, and those skilled in the art should make various changes or substitutions within the spirit of the present invention, and shall fall within the protection scope of the present invention.
