Sequence of mechanical actions of the whole device:

when the device of the present invention is operated, when a driver steps on the brake pedal 34 to brake, the brake pedal 34 rotates to drive the first piston plate 38 to move downward, so that the air in the first piston chamber 37 enters the third piston chamber 83 through the second pipe 39, so that the second piston rod 84 moves into the sixth transmission chamber 70, so as to drive the lower sliding shaft 69 to move toward the power shaft 11, so that the lower friction wheel 73 contacts the power shaft 11, so as to drive the lower friction wheel 73 to rotate, so as to drive the lower fifth pulley 74 to rotate, so as to drive the third pulley 67 to rotate, so as to drive the sixth rotating shaft 53 to rotate, so as to drive the coil 45 and the first speed changing pulley 55 to rotate, so as to drive the seventh rotating shaft 58 to rotate, so as to drive the rotating wheel 59 to rotate, thereby driving the second sliding rod 64 to move left and right alternately, so that the decelerating plate 65 clamps the power shaft 11 intermittently to decelerate the power shaft 11, the fifth gear 66 rotates to drive the third gear 28 to rotate, thereby driving the fourth gear 26 to rotate, thereby driving the fourth bevel gear 23 to rotate, thereby driving the first bevel gear 41 to rotate, thereby driving the first rotating shaft 42 to rotate, thereby driving the coil 45 to rotate and cut the magnetic induction lines, thereby the electric conductor 43 generates electric current and is collected in the battery 32 through the conducting wire 33, when the driver steps on the brake pedal 34 with a large force, more gas in the first piston cavity 37 enters into the second piston cavity 50, thereby driving the first piston rod 51 to move up, thereby driving the spline shaft 52 to move up, thereby driving the second variable speed pulley 54 to move up, so that the seventh rotating shaft 58 rotates faster, and the rotating wheel 59 rotates faster, and the decelerating plates 65 clamp the power shaft 11 at a faster speed, and the power shaft 11 decelerates faster, and when the driver steps on the brake pedal 34 with a larger force, more gas in the first piston chamber 37 also enters the third piston chamber 83, so that when the second piston plate 82 moves to the third pipe 81, the gas in the third piston chamber 83 can enter the fourth piston chamber 78, and the third piston plate 79 slides toward the sixth transmission chamber 70, and the upper sliding shaft 69 is driven to move toward the power shaft 11, so that the upper friction wheel 73 contacts the power shaft 11, and the upper friction wheel 73 is driven to rotate, thereby rotating the fifth belt pulley 74 at the upper side, and further rotating the sixth belt pulley 77, and further rotating the sixth gear 75, and further rotating the second gear 20, and further rotating the first gear 18, and further rotating the third bevel gear 16, and further rotating the second bevel gear 14, and further rotating the third rotating shaft 15, and further rotating the second belt pulley 13, and further rotating the first belt pulley 48, and further rotating the fixing block 46, and further rotating the magnet 44, so that the magnetic induction wire cutting speed is increased, and the generated current is increased, and the above-mentioned power generation speed and deceleration effect are also affected by the rotating speed of the power shaft 11, and the power generation speed and deceleration effect are better when the rotating speed of the power shaft 11 is faster.
