Electric vehicle handle collapsing device

Abstract

An electric vehicle handle collapsing device for an electric vehicle includes a fundamental base, a fitting fork tube, a combining member, an operating member, a subordinate rod, a pull spring and a locking device. After the locking device is released and the pull plate of the operating member is pulled upward, the subordinate rod is forced to move upward and disengaged from the front engage notches and then moved in the rear engage notches of the fundamental base by a pulling force of the pull spring. Thus, the handle of an electric vehicle can be collapsed to diminish the dimensions of the electric vehicle, letting the electric vehicle carried about conveniently.

What is claimed is:  
     
         1 . An electric vehicle handle collapsing device comprising: 
 a fundamental base fixed at the front end of a foot rest of an electric vehicle, said fundamental base formed with plural curved edges on top, said curved edges respectively bored with a front and a rear engage notch;    a fitting fork tube composed of a sleeve and a fork tube, said sleeve fitted around a handle of said electric vehicle, said fork tube assembled with said fundamental base, said fork tube bored with a vertical slot at the lower portion of the left and the right side and a plurality of vertical upper and lower sliding slot at proper locations of the front and the rear side;    a combining member connecting said fitting fork tube with said fundamental base;    an operating member assembled with said fork tube and provided with at least an insert plate, said insert plate inserted in said fork tube through said upper sliding slot, each said insert plate bored with an insert hole at a lower portion, said operating member provided with a pull plate in front;    a subordinate rod inserted through said vertical slots of said fork tube and said insert holes of said operating member, said subordinate rod also engaged in said engage notches of said fundamental base;    a pull spring having its opposite ends respectively clasping said subordinate rod and said combining member; and,    said pull plate of said operating member pulled upward, said pull plate making said subordinate rod move upward and disengaged from said front engage notches of said fundamental base, said subordinate rod forced to move in said rear engage notches of said fundamental base along said curved edges by a pulling force of said spring, thus said handle able to be collapsed downward to diminish the dimensions of said electric vehicle, convenient for said electric vehicle to be carried about.    
     
     
         2 . The electric vehicle handle collapsing device as claimed in  claim 1 , wherein said fundamental base has its opposite sides respectively provided with a side plate having a central through hole.  
     
     
         3 . The electric vehicle handle collapsing device as claimed in  claim 1 , wherein said fork tube has its opposite ends respectively bored with a positioning hole aligned to said central through hole of said side plate of said fundamental base for said combining member to be inserted therethrough.  
     
     
         4 . The electric vehicle handle collapsing device as claimed in  claim 1 , wherein said operating member has its front side disposed with a front plate to rest against the front wall of said fork tube, and the front plate is bored at a lower portion with a through hole matching with said sliding slot of said fork tube.  
     
     
         5 . The electric vehicle handle collapsing device as claimed in  claim 1 , wherein said subordinate member has its opposite ends respectively fitted with a stop member to resist against the outer walls said two side plates of said fundamental base to prevent said subordinate rod from slipping off, said subordinate rod is bored in the center with a through hole facing said through hole in said front plate of said operating member and said lower sliding slot of said fork tube.  
     
     
         6 . The electric vehicle handle collapsing device as claimed in  claim 1 , wherein said handle collapsible device is provided with a locking device to be assembled with said operating member and said fork tube for tightly clamping and locking said operating member, and said locking device consists of a threaded rod having a pull lever fitted at the front end, a tightening member fitted around said threaded rod, a clasping block clasping the front side of said operating member and having a through hole facing said through hole of said front plate of said operating member, a resisting member fitted around said threaded rod and resisting against the rear wall of said fork tube, and a spring and a nut respectively fitted around and screwed with the end of said threaded rod.
