Abstract

The invention relates to a folding pedal plate. In a combined structure including central-axle rectangular flat axle heads, central-axle hollow cavity type axle heads, central-axle circular axle heads, crank folding connecting heads, a left crank, a right crank, a crankset, step tread plates, crank axles, crank tail end connecting heads, crank axle connecting heads, connecting axle centers, axle holes and a central axle, the head central parts, close to one folding and mobile ends, of the central axles in vertical corresponding directions of the unfolded cranks are made into rectangular flat axle heads from top to bottom; and U-shaped forks, which are formed in such a way that two sides of the crank connecting heads are forked, are forked on the flat heads of the central axles; or the central axles are made into axle heads with rectangular clearance slots, and the parts where the cranks are connected with the crank connecting heads are made into rectangular convex head plugs; or the central axles are made into spherical axle heads, the parts where the cranks are connected with the crank connecting heads are made into hollow spheres which can sleeve circular heads of the central-axles, and the connecting axle centers penetrate through the axle holes to connect the hollow spheres so as to form a frame.

Description

Folding pedal plate

Art

The present invention relates to a kind of foot pedal structure of the part of the foot-operated drive system of bicycle, electric motor car.

Background technology

At present, known bicycle, the pedal of electric motor car cannot be folded.

The content of the invention

For the shortcoming for overcoming existing bicycle, electric vehicle pedal fold, the present invention provides one Plant folding pedal plate.

The present invention solves the technical scheme that adopted of its problem：Where foot-operated crank and axis connection It is designed to folds and also make where crank shaft and the connection of crank tail end inside the structure of activity, step tread plate Into the structure that can fold activity；Foldable structure is divided into fixed and movable two parts and passes through axle by axle center is connected Connect and the foot pedal structure of the activity of can folding that is fixed together, formed, the fixed part inside foldable structure in hole Part and movable part mutually can be exchanged, fixed shape and structure can be used in movable part, work Dynamic shape and structure can be exchanged used in fixed part, and foldable structure has many kinds, illustrated three kinds, and one It is：One section of 3 to 10 centimeters is reserved on the head of folding activity one end in axis to roll in centre and not Folded crank vertical direction be made in the middle of a long quad flat spindle nose, the quad flat spindle nose of length from top to bottom from Side opens one can be with connection axis hole of the axle center tandem crank together with axis, crank connection axis connection Where head, both sides jag forms a U-shaped fork fork and is worn with connection axle center on the quad flat spindle nose of the length of axis The structure that axis hole is joined together to form folding activity is crossed, U-shaped fork be free to be enclosed within the quad flat axle of axis length Folded on head up and down with formed and fixed the upper folding activity in alignment of another not folded crank shape, Latter two crank and pedal that point is folded centered on axis forms the right and left position on same straight line Put, open two cranks in left and right and pedal after folding and expanding on same straight line formation level opposition one With regard under one on individual, with regard to the opposition angle position after before one；Two are：In axis near folding activity One section that 3 to 10 centimeters are reserved on the head of one end is arrived from above in centre and not folded crank vertical direction Under be fabricated in the middle of the spindle nose of a rectangle clearance groove, clearance groove spindle nose open one from side can be with connection Axis hole of the axle center tandem crank together with axis, crank connection axis union joint where be fabricated to one it is long Square plush copper plug inside the rectangle clearance groove spindle nose of axis, and then with connection axle center through axis hole connection The structure of folding activity is formed together, and the rectangle plush copper of crank is free in axis rectangle space Inside groove, folding activity, folding are in alignment to form and fix another not folded crank shape up and down Upper folding activity, latter two crank and pedal that centered on axis, point is folded are formed on same straight line After the right and left position, opening folding and expanding, two cranks in left and right and pedal form water on same straight line With regard under one on of flat opposition, with regard to the opposition angle position after before one；Three are：Lean in axis One section of 3 to 10 centimeters is reserved on the head of nearly folding activity one end in centre and another not folded Crank vertical direction is made in the middle of the head of a spheroidal, the head of axis spheroidal from top to bottom and opens from side door One can be used the ground that connection axis hole of the axle center tandem crank together with axis, crank connect axis union joint Side is fabricated to spherical being enclosed within above the orange of axis of open circles and is connected to one through axis hole with connection axle center The structure for forming folding activity is acted, the open circles spherical member of crank can be enclosed within the spindle nose of axis spheroidal Carry out up and down folding and lived with forming and fixing another not folded crank shape upper folding in alignment Latter two crank dynamic, that point is folded centered on axis and pedal form the right and left on same straight line After position, opening folding and expanding, two cranks in left and right and pedal form level opposition on same straight line With regard under one on one, with regard to the opposition angle position after before one；The link of crank shaft and crank tail end The folding movable part of head also has many mode structures, and the pedal of left and right two can be to be formed to fold with crank Structure, illustrate two methods, be respectively：First, the tail end in crank reserves the one of 1 to 6 centimeters Cut and be made in the middle of the head of the word length of falling a T square flat, homalocephalus from top to bottom from side in core and pedal Men Kaiyi can be connected with connection axis hole of the axle center tandem crank together with crank shaft, crank shaft connecting crank Where joint, both sides jag forms a U-shaped fork fork and is passed through with connection axle center on the homalocephalus of crank tail end Axis hole is joined together to form the structure of folding activity, and U-shaped fork be free to be enclosed within the homalocephalus of crank tail end Fold up and down, no longer roll over where U-shaped fork folds into a horizontal stroke of inverted T-shaped rectangle homalocephalus bottom transverse support Fold down, the open angle that the folding span of such pedal and crank is 90 degree, pedal and crank is formed 90 degree of square is easy to trample；2nd, the tail end in crank reserve one section of 1 to 6 centimeters in core and Pedal is made into the spindle nose of one rectangle clearance groove of a word of falling T, the word length of falling T square interstice from top to bottom The spindle nose of groove opens one from side door in centre can be with connection axle of the axle center tandem crank together with crank shaft Where hole, crank shaft connecting crank union joint, both sides form a rectangular plush copper set and fill in axis It is joined together to form the structure of folding activity above rectangle clearance groove spindle nose with connection axle center through axis hole, The rectangle plush copper of crank shaft be free to up and down to T inside crank tail end rectangle clearance groove I.e. refolding has not been gone down, the folding span of such pedal and crank is for the whippletree position of word length square interstice groove 90 degree, the open angle of pedal and crank forms 90 degree of square and is easy to trample；

The invention has the beneficial effects as follows：The bicycle and electric motor car of folding pedal plate is made after folding or not With when can reduce and take up room and position.
