Be example with vehicle through the deceleration strip on the plane, analyze working procedure of the present utility model, during wheel process deceleration strip wedge 1, under the brakeless situation, automobile kinetic energy is converted into gravitational potential energy, wheel leaves deceleration strip wedge 1 and rolls deceleration strip flat board 2, driving tooth bar 4 moves down rapidly, elastic member 3 compressions, gear ring 5 rotates and drives step motor shaft 7 and rotates, and reaches the purpose of generating.In the automobile decline process, elastic member 3 elastic force constantly increase, and the automobile rate of descent is reduced rapidly, guarantee that automobile balance ground is through deceleration strip flat board 2.After wheel left deceleration strip flat board 2, the potential energy that elastic member 3 stores discharged, and deceleration strip flat board 2 is resetted.Simultaneously, the active of overrunning clutch 6 produces relative movement with secondary part, the rapid stop motion of active part, and secondary part continues to drive step motor shaft and rotates generating under effect of inertia.
Major parameter of the present utility model is analyzed as follows:
Suppose below each deceleration strip dull and stereotyped 2 four pairs of springs to be installed
(1) the elasticity coefficient K of spring: when spring force was just identical to the pressure of deceleration strip flat board with automobile, spring can fully compress, and tooth bar has bigger speed driven gear and rotates, and supposed to have only one to arrange wheel and roll deceleration strip, had:
The underground parking garage slope:
The underground parking garage level land:
Wherein, Δ l is spring largest deformation amount, and α is inclination angle, underground parking garage slope, K
