A plantar energy storage booster, comprising a fixed plate and an elastic plate;
- wherein said fixed plate is arranged for being placed on a sole of a foot and worn by the foot of a user, wherein a rear end of said fixed plate is configured to extend behind a heel of the user;
- wherein said elastic plate is made of elastic deformable material, wherein said elastic plate is formed in an arc-shape along its longitudinal sectional direction, wherein said elastic plate is located below said fixed plate, wherein in a natural initial state, said elastic plate has a front end fixedly connected to a front end of said fixed plate and a rear end spaced apart from a rear end of said fixed plate to define an energy storage gap therebetween in a vertical direction;
- wherein said energy storage gap is gradually reduced when said rear end of said elastic plate as a fulcrum is pressed downwardly via a vertical pressure applied by said heel to said fixed plate, at the meantime, wherein said elastic plate is forced to be deformed for storing a portion of kinetic energy generated by the vertical pressure exerted by the heel to said fixed plate for deforming said elastic plate,
- wherein said plantar energy storage booster further comprises:
- a boosting mechanism provided between said fixed plate and said elastic plate for converting the kinetic energy stored in said elastic plate into an upward and forward force to be applied to said fixed plate after the heel is lifted,
- wherein said boosting mechanism comprises a thrust assembly provided at mid-portions of said fixed plate and said elastic plate, and a starting assembly provided at said rear ends of said fixed plate and said elastic plate,
- said starting assembly is configured to trigger said thrust assembly to start working after the heel is lifted, and
- said thrust assembly is configured to be driven by said starting assembly to generate the upward and forward force to the fixed plate,
- wherein said starting assembly comprises a guiding member provided at said rear end of said fixed plate, a driving rod provided at said rear end of said elastic plate and extended upwardly, and a swing lever pivotally coupled at a mid-portion of said fixed plate, wherein said guiding member has a front end coupled at said fixed plate, wherein a guiding groove is upwardly extended and provided at a rear end of said guiding member, wherein said starting assembly further comprises a ratchet tooth provided at an upper end of said driving rod, wherein a lower end of said driving rod is coupled to said elastic plate, wherein said driving rod with said ratchet tooth are arranged to move up and down along said guiding groove, wherein said swing lever has an arc-shaped configuration and a width gradually increased from a rear end of said swing lever to a front end thereof, wherein said rear end of said swing lever is a free end and comprises at least one hanging tooth, wherein said front end of said swing lever has an inclined lower surface inclinedly and upwardly extended from front to back, wherein a sliding groove is formed at said front inclined surface, wherein said thrust assembly is coupled at the sliding groove of said swing lever to slide up and down along said sliding groove, wherein said ratchet tooth is able to freely slide at and pass said ng tooth when moving upward from a bottom of said hanging tooth, and is engaged with said hanging tooth when moving downward from a top of said hanging tooth, wherein when said ratchet tooth is continuously moved downward via said driving rod, said ratchet tooth is configured to drive said swing lever to swing and push a lower end of said front inclined surface of said swing lever forward.
