Description
Technical field
It is one kind by (can also be other similar vehicles, herein to bicycle the present invention relates to mechano-electronic field
Signified bicycle may be applicable to other similar vehicles) it is foot-operated（Foot-operated i.e. foot pedal herein, is used with according to custom）Plate into
Row is transformed to realize that bicycle pedal auto Deformation is punctured into the invention of compact thin shape.Use the bicycle of the invention
The foot pedal to take up space very much that two turn up can be collapsed automatically thinning, coordinate the automatic contraction of the other parts of bicycle,
It is a kind of automatic contraction invention that can be saved bicycle pedal and be taken up space to be not take up the space of storing bicycle.
Background technology
With becoming increasingly popular for shared bicycle, the drawbacks of sharing bicycle while being brought convenience to people, share bicycle
It is fairly obvious:Bicycle is disorderly parked, and occupancy public space is more, seriously affects appearance of the city etc.;Invention before the present inventor " blade
Formula auto Deformation bicycle self-service sharing method " has invented a kind of method that can allow bicycle auto Deformation, by the method, from
Driving in the box of storehouse, can not only very easily provide available bicycle, and eliminate by uniform compressed collecting
All drawbacks of aforementioned general shared bicycle；It is in the contraction distortion of bicycle, the component of left and right stretching, extension in bicycle is complete
Portion be punctured into it is front and back or up and down stretching, extension can save a large amount of memory spaces, foot pedal stretches that the position accounted for is very wide and foot to the left and right
The automatic contraction of pedal is the most complicated：Because foot pedal rotates on two dimensions：One is that foot pedal rotates together with crank
Bicycle is driven to move ahead, one is that foot pedal own layer itself is being rotated to be stepped on always by foot when ensureing in circular motion repeatedly
On the same face.
Invention content
In order to allow bicycle（Bicycle of the present invention also includes the similar vehicles such as electric assisted bicycle and electric bicycle）
Trip is more intelligent convenient, and the present invention shrinks foot pedal to bicycle pedals automatically（Plate, similarly hereinafter）Realize automatic contraction, to
Foot pedal occupied space is reduced, achievees the effect that improve space availability ratio.
The technical solution adopted by the present invention to solve the technical problems is：A chargeable electricity is placed on cycle frame
Pond takes electricity by rotation（Brush or wireless induction mode）Power supply or control signal are transmitted to foot pedal from cycle frame
On the crank depended on；Have electric actuator on crank, by this electric actuator drive foot pedal overall shrinkage (to
Upper and lower or left and right contraction)；Axis is nearby filled there are one motor on vehicle frame, which can drive axis to revolve by gear etc.
Turn, and the rotation of axis is foot-operated with movable chain wheel and crank and entirely（Plate）Around middle shaft rotation（As long as other can drive axis to revolve
The scheme turned treats as equivalent program）, such foot pedal is during overall shrinkage draws close vehicle frame, foot pedal own layer quilt
It gradually stretches parallel with vehicle frame plane to complete the complete contraction of foot pedal；The junction of foot pedal and crank, is provided with one
A holding meanss, the holding meanss make the rotational resistance between foot pedal and crank when foot pedal plane is parallel with vehicle frame plane
Maximum is so that can only be in external force（As foot is stepped on）Rotation is just separated under effect.
The realization principle of the present invention is described as follows：
Rechargeable battery is placed in bicycle, crank follows middle shaft rotation band movable chain wheel, chain wheel to drive chain rotation, chain
Band motor car wheel rotates；When people rides, foot pedal is firmly stepped on, foot-operated to connect together with chain wheel, chain wheel is linked togather with crank
Axis of ining succession rotates together；Normal when riding, regardless of foot pedal own layer rotation, foot pedal plane is and chain wheel always
Plane（That is vehicle frame plane）Vertical, it is foot-operated in order to shrink（The purpose of contraction will be ridden shared by bicycle left and right directions
Space length is kept to minimum so that it is convenient to automatic storing, compressed storage space）, it is necessary to when not riding by foot pedal plane
Become and chain wheel plane（That is vehicle frame plane）Parallel position and keep this state when passing in and out the dedicated storehouse box of bicycle
To occupy minimum memory space, foot pedal needs motor drive mechanism (generally to be described with motor, other actuating units principle one
Sample) it drives and shrinks, motor will operate firstly the need of electricity, and since foot pedal relative to bicycle rack has rotary motion, institute
It is infeasible so that line takes electricity directly from vehicle frame, it is necessary to take rotation way to take power that power supply is referred to crank from vehicle frame
On, rotation takes the mode of electricity to have very much, mainly brush rotation power supply and wireless charging mode, and brush power supply can be taken in axis
Upper setting copper ring, axis, which is placed in bearing, to be rotated, and bearing case is fixed on vehicle frame, and axis rotates in bearing case, axis
Hold and be disposed with brush on shell, brush elasticity presses on axis copper ring, when middle shaft rotation brush by Elastic Contact by electric power
Axis is passed to, since axis is to be fixedly connected with crank, to which the motor on crank obtains electric power；For wireless charging mode
Power supply does not influence power supply mode due to being non-contact power whether rotation（Ensure that coil corresponds to）.When crank is powered
Afterwards, electric power mechanism（Such as motor or electromagnet）Control signal can also be introduced by brush or wireless communication mode.
When needing to shrink foot pedal, electric power mechanism will drive entire foot pedal to shrink (up and down or left and right contraction),
Due to foot pedal own layer be also one can be around the rotary body rotated with the junction of crank, so foot pedal is by primary
Up and down or after the contraction of left and right, the foot pedal own layer uncertain moment is maintained on the direction parallel with vehicle frame plane, in this way
May be more than the crank that depends on of foot pedal due to foot-operated width when foot-operated overall shrinkage draws close bicycle rack to vehicle frame
Distance can not collapse completely so as to cause due to foot pedal width blocks, therefore need foot-operated to what is integrally collapsed（Plate）Do secondary receipts
Contracting：For dress there are one motor, which can drive middle shaft rotation by modes such as gears near axis i.e. on vehicle frame, in this way when
It is foot-operated whole during vehicle frame is drawn close in contraction, since axis dallies under the drive of motor（I.e. without motor car wheel）Rotation
Turn, for foot pedal during gradually drawing close vehicle frame, the rotation of axis drives entire chain wheel and crank around middle shaft rotation, so foot
Pedal plane is gradually stretched parallel with vehicle frame plane to complete the complete i.e. secondary contraction of contraction of foot pedal；Due to common foot
Pedal cannot remain fixed on face parallel with vehicle frame plane always（Because foot pedal own layer rotates freely）, it is
It shrinks completely in foot pedal（I.e. by shrinking twice）When foot pedal plane is maintained in the plane parallel with vehicle frame plane
（It least takes up space in this way）, in the junction of foot pedal and crank, there are one holding meanss for setting, and the holding meanss are in foot pedal
Plane so that the rotational resistance between foot pedal and crank is maximum when parallel with vehicle frame plane.The holding meanss use magnetic force or ripple pearl
The on-fixeds connection type such as screw, to both can guarantee that in complete shrink, foot pedal own layer energy stable state is maintained at and vehicle frame
In plane parallel direction, but when normally riding foot step on power under can rotate freely.
The beneficial effects of the invention are as follows can easily be shunk automatically by foot pedal using the present invention, occupy laterally
（Left and right）Space is minimum, stores automatically to convenient and greatlys save parking space（One general park position can park
Hundred bicycles）；Since the bicycle of contraction regularly can be automatically stored in special storehouse box, to bring good warp
Benefit of helping and ease of use；Solves the space of shared bicycle together with other related inventions of what is more important and the present inventor
The problems such as occupancy is big, and the appearance of the city is untidy.

It is negative, controls one brush of signal, microcontroller is placed on crank and receives control signal and controls electric power execution machine
Structure is all made of miniature DC geared motor in electric actuator the present embodiment（Have the big feature of small torque, it completely can be with
Drive crank and foot-operated rotation）；The strategy that foot pedal is shunk in the present embodiment is by foot pedal from the left and right directions normally ridden
Rotating shrinking is front-rear direction（I.e. by the way that crank is divided into two parts, top half is fixed on axis, and lower half portion can revolve
Turn, top half is equipped with motor, and motor rotation drives crank lower half portion that can the left and right direction of foot pedal be changed to front and back court
To）.Rotation rear pedal direction becomes front-rear direction from left and right directions（I.e. left and right is shunk；And shrink up and down, refer to it is foot-operated from
Left and right directions becomes upper and lower directions, and the mode of steel wire pull line can be taken to realize contraction up and down；The i.e. foot-operated plane in foot-operated direction
Long side direction）.
Foot-operated first time overall shrinkage takes the reduced technique before and after left/right rotation, i.e., rides left and right when normally riding
Direction（See and rides direction in Fig. 3）Rotate to be front-rear direction（See and rides direction in Fig. 4）.Crank（2）It is divided into two parts up and down,
Crank top（5）Being fixed on dress on axis, there are one rotary movable joints（7）, the turning joint (7) is on crank
Miniature slowdown DC motor, that is, crank motor (8) control under can be around motor shaft（11）In ball（10）Upper rotation, it is bent
Handle motor（8）Power supply and signal control line（9）By axis（1）On copper ring（15）Through brush（14）By the charging on vehicle frame
Battery introduces, foot pedal（4）It depends on and is mounted on crank lower part（6）Under；Foot pedal is convenient towards left and right directions when normally riding
Left and right foot, which is stepped on, rides, but rotary moveable joint at the end of riding（7）In motor（8）Control under be rotated by 90 ° rear pedal and be changed to court
Forward and backward；Because of foot pedal（4）Own layer is rectangular, so its long side direction is referred to as foot pedal side herein
To, ride（4）By towards left and right directions（Shown in Fig. 3）It is changed to towards front-rear direction（Shown in Fig. 4）Complete foot pedal（4）
It is primary to shrink.
Foot pedal（4）During becoming front-rear direction from left and right directions, due to foot pedal（4）It entirely not only can be with song
Handle（2）, chain wheel（3）Axis is surrounded together（1）Rotation, and foot pedal（4）Own layer can also surround crank lower part（6）Connection
Locate self rotation, so must also take once i.e. secondary contraction method to complete foot pedal（4）Complete contraction：I.e. first
Secondary to shrink entire foot pedal, shrink foot pedal own layer again for the second time (becomes parallel with vehicle frame plane by foot pedal plane
To be further reduced space hold).Shrink for the first time becomes front-rear direction by entire foot pedal long side from left and right directions, and second
It is secondary shrink to foot pedal own layer shunk i.e. by foot pedal Planar Contraction be and vehicle frame plane（Vehicle frame plane namely after
Take turns this disk）Parallel direction.Nearby there are one vehicle frame motors for dress for axis on vehicle frame（13）, which passes through gear（12）Deng
Axis can be driven（1）In bottom bracket bearing（16）Middle rotation, and the rotation of axis band movable chain wheel（3）And crank（2）And it is entire
It is foot-operated（4）It dallies around axis（I.e. chain reversion only axis chain wheel turn, wheel does not turn, idle running the purpose is to reduce vehicle frame motors
Power size）, such foot pedal（4）It is whole during vehicle frame is drawn close in contraction, foot pedal own layer gradually stretched with
Parallel second of the contraction to complete foot pedal of vehicle frame plane is shunk completely（See Fig. 5）.
Heretofore described vehicle frame is simultaneously not folded, it is therefore an objective to keep two wheels be in normal front-rear direction convenient for automatically into
Export box, the various bicycle assembly parts of both sides stretching, extension are retracted thinning to occupy minimum memory space.After shrinking twice
Foot pedal（4）Become not taking up space additionally in fully collapsed condition and from one of the component most to take up space（With crank and vehicle frame
Etc. shared parking space）Component.
The junction of foot pedal and crank, there are one foot-operated plane holding meanss for setting（17）, the holding meanss（17）It adopts
With magnetic force on-fixed connection type, i.e., foot-operated on crank there are one magnet with the setting of crank junction, when foot-operated plane is in
When parallel with vehicle frame plane, because foot-operated（4）Iron nail is contained in the place of the face magnet, at this time because iron nail and magnet are apart from most
Closely, so under the attraction of magnetic force, it is that will not leave the position parallel with vehicle frame plane in the absence of external forces to ride.But
Be this electromagnetic force it is very little, foot is stepped in the above or can be rotated freely when people normally rides.That is foot
Smash face holding meanss（17）Both it can guarantee that foot pedal own layer energy stable state was maintained at flat with vehicle frame plane in complete shrink
On line direction, but when normally riding foot step on power under can rotate freely.When foot pedal plane is parallel with vehicle frame plane
When the holding meanss make the rotational resistance between foot pedal and crank maximum so that can only be in external force（As foot is stepped on）Effect is got a foothold
Pedal plane just separates rotation.
