The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.The utility model discloses the energy storage equipment of a kind of use on the wheeled car of being controlled by rider, this device can store rider in the excess energy that reinforcing district B uses, and effectively discharge at weak district A, thereby the moving velocity of wheeled car when promoting weak district A, especially vehicle climb and during low cruise effect remarkable.Concrete structure is: this energy storage equipment comprises shell 1, accumulation of energy part, energy release portion and the reversing part 7 of unblanking, and accumulation of energy part and energy release portion are arranged in shell 1.Accumulation of energy partly comprises ratchet device I 2, holds power dish 5 and holds power spring 8, the ratchet I of ratchet device I 2 with hold power dish 5 and captive joint, namely by tie bolt both are connected.In the present embodiment, hold power spring 8 and be torque spring, an end that holds power spring 8 is connected and holds on the power dish 5.The energy release portion comprises torsion release dish 11, and the other end that holds power spring 8 is fixed on the torsion release dish 11.The reversing part 7 of unblanking comprises ratchet device II 3, reversing lock collar 6 and lock pin 15, and the ratchet II of ratchet device II 3 is captiveed joint with reversing lock collar 6, and lock pin 15 is inserted in the lock collar 6 of moveing backward.Shell 1 comprises fore shell and tail-hood, is connected with bolt between fore shell and the tail-hood, is provided with tail-hood bearing 13 between tail-hood and torsion release dish 11.
The invention also discloses a kind of bicycle that uses this energy storage equipment, this bicycle has axis 4, is installed in wheel disc 10 and foot-operated crank 14 on the axis 4, energy storage equipment is installed on the axis 4, between two foot-operated cranks 14, the torsion release dish 11 of energy storage equipment is captiveed joint with wheel disc 10, between torsion release dish 11 and the axis 4, hold between power dish 5 and the axis 4 and be equipped with bottom bracket bearing 12.This energy storage equipment also comprises the reversing part 7 of unblanking, and the reversing part 7 of unblanking comprises ratchet device II 3, reversing lock collar 6 and lock pin 15, and the ratchet II of ratchet device II 3 is captiveed joint with reversing lock collar 6, and lock pin 15 is inserted in the lock collar 6 of moveing backward.Be connected with brake cable at lock pin 15, the other end of this brake cable is installed on the handlebar of bicycle.
When riding bicycle, foot-operated crank 14 drives axis 4 and rotates, when foot-operated crank 14 turns to afterburning district, be applied to application force on the foot-operated crank 4 greater than the torsion that holds power spring 8, the kinetic energy that has more drives the ratchet I unidirectional rotation of ratchet device I 2, and and then the power of the holding dish 5 that is fixed together of drive and ratchet I rotate, finally make an end and hold the power of holding spring 8 twistings that power dish 5 links together, unnecessary kinetic energy is converted into the potential energy that holds power spring 8 stores.When foot-operated crank 14 turns to weak district, be applied to application force on the foot-operated crank 14 when holding the torsion of power spring 8, be stored in the rotation by torsion release dish 11 of the potential energy that holds on the power spring 8 and outwards discharge, and and then driven wheel dish 10 rotate, reach purpose laborsaving, acceleration.As seen, use this energy storage not only to can be used to easily overcome the dead center position that exists in the foot-operated crank motion, and be stored in the potential energy that holds on the power spring 8 and can outwards discharge at any time, wheel disc 10 is accelerated, namely the speed of wheel disc 10 is that axis 4 coils 11 coefficient results with torsion release.In riding, this bicycle can freely be moveed backward and is not affected.
The unblank effect of 7 pairs of these bicycles of part of reversing is: when by after being installed in brake cable on the handlebar lock pin 15 being mentioned, then energy storage equipment is inoperative, and this bicycle is exactly an ordinary bicycle, can realize freely moveing backward.
Need to prove that especially the unidirectional drive parts in the present embodiment have been selected ratchet device for use, in addition, also can select mono-directional overrun clutch for use.The advantage of ratchet device is to use the reliability height, but noise is big, and mono-directional overrun formula power-transfer clutch does not have noise, but its poor reliability.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
