Detailed description of the invention
The embodiment of the present invention 1 is a kind of Electrical Bicycle, and its trailing wheel is power wheel, built-in wheel hub motor.Battery, controller is had in car.After vehicle frame folding, car load is upright case shape, trailing wheel under land, handlebar has switch make car can enter the constant-speed operation state of the speed of being careful so that upper downstairs.Fig. 1 is the power wheel structural representation with the Electrical Bicycle of climbing building function of the present embodiment 1.
In Fig. 1, dynamic wheel 2 is arranged on vehicle frame 1, is fixed on the brake disc 5 on power wheel coaxially and the binding clasp 7 be arranged on auxiliary wheel carrier 4 constitutes a kind of arrangement of clutch, and binding clasp 7 is bistable devices, Fig. 2-1, Fig. 2-2 respectively illustrates two state.Driving lever 8, for changing the state of binding clasp 7, to be pushed outward along power wheel radial direction when driving lever 8 and more than a transformation point, then to fall within locked position, and now brake disc 5 is clamped, and power wheel 2 and auxiliary wheel carrier 4 are fixed; When driving lever 8 is pushed inwardly postcritical, then will fall within releasing position, now binding clasp 7 and brake disc 5 depart from, thus auxiliary wheel carrier 4 can freely rotate.Sealed push rod 6 is made up of fixed arm and movable arm, fixed arm is fixed on vehicle frame, its front end is connected with movable arm by pivot pin, and have spring between the two, under making free state, the front end of sealed push rod movable arm is positioned in the motion circular path of driving lever 8 under binding clasp 7 release position, and downward, when auxiliary wheel carrier 4 moves, then driving lever 8 collides the front end of sealed push rod movable arm, drive it to sway, make to be tending towards stretching by bending between itself and sealed push rod fixed arm, thus its front end edge power wheel footpath is outwards moved, promote to move outside driving lever 8, binding clasp 7 is made to fall into locking state, Fig. 3 shows the final condition of this process.The design of sealed push rod makes to promote driving lever 8 and moves to from its releasing position and exceed critical spot, and thereafter auxiliary wheel carrier 4 still can on move and do not destroy structure.If binding clasp 7 is locked, auxiliary wheel carrier 4 moves with on power wheel 2, then, when driving lever 8 contacts upper unblock limiting device 10, driving lever 8 is extruded inward promotion with the rotation of power wheel, until postcritical enter release position after auxiliary wheel carrier 4 no longer on move, reach spacing object.The effect of lower unblock limiting device 9 and similar.
Preferably, described upper and lower unblock limiting device is respectively the baffle plate of a curved surface, and Fig. 4 shows curved baffle and realizes unlocking spacing process.
When the present embodiment is used for topping bar, by elastomeric element (as spring), jockey pulley 3 is kept certain height, make its axle be in position a little more than step, and the setting angle of sealed push rod 6 makes the front end in contact driving lever 8 of now sealed push rod movable arm.When jockey pulley 3 contacts step, to be pushed and move, at this moment promotion driving lever 8 footpath is outwards moved by sealed push rod movable arm, makes binding clasp 7 be locked in brake disc 5, thus jockey pulley 3 outshot that also equivalently become power wheel 2 fixing with power wheel 2, power wheel 2 and car body move on fulcrum with jockey pulley 3.When power wheel 2 substantially arrives on step after plane, binding clasp driving lever 8 also touches lower unblock limiting device, and promotes binding clasp 7 and get back to releasing position, and at this moment under the effect of above-mentioned elastomeric element, jockey pulley 3 gets back to initial position, completes process of once topping bar.Need secondarily driven forward car body to make jockey pulley 3 rolls forward in the process, guarantee that power wheel 2 contacts step all the time.
When the present embodiment is used for getting out of a predicament or an embarrassing situation, cancel the effect of above-mentioned elastomeric element, make auxiliary wheel carrier 4 naturally drop to the lower rear of power wheel working direction, and sealed push rod adjusts, and makes the front end of sealed push rod movable arm higher than driving lever 8 downwards, and be in suitable height.When power wheel rolls across the decline of step turning, auxiliary wheel carrier 4 is pushed and moves, the front end of sealed push rod movable arm touched by driving lever 8, extrapolated by radial direction, make binding clasp 7 lock brake dish 5, thus jockey pulley 3 and power wheel 2 are fixedly equivalent to the outshot of power wheel 2, suitably brake controls the rotating speed of power wheel, then power wheel and car body are with jockey pulley 3 for fulcrum moves down, and realize slow falling.And the auxiliary wheel carrier 4 after locking is still with power wheel rotation moves, when arriving upper unblock limiting device, pushed unblock, thus auxiliary wheel carrier 4 falls naturally, automatically returning to initial condition, completing process of once getting out of a predicament or an embarrassing situation, process of next time getting out of a predicament or an embarrassing situation can be started.
Unlock limiting device in the present invention extremely important for structural safety, it has multiple possible concrete methods of realizing.
Embodiments of the invention 2 are a kind of Electrical Bicycles using drag-line mode to realize unlocking limiting device.In Figure 5, limiting device is made up of jointly drag-line 11 and limited post 12.Drag-line 11 connects the wheel shaft position of driving lever 8 and vehicle frame 1.At the locking state of binding clasp 7, drag-line 11 is straightened but does not affect binding clasp state.Limited post 12 is relative with vehicle frame 1 is fixedly arranged at appropriate location, and with the motion scan Plane intersects of drag-line 11.In Fig. 6, when auxiliary wheel carrier moves down, drive driving lever 8 to move down, limited post 12 stops the scanning pattern of drag-line 11 and makes drag-line 11 bending, thus shortens radical length, and make to move in driving lever 8, binding clasp proceeds to release position, thus can reach the effect same of embodiment 1.
Fig. 5,6 shows and uses drag-line to coordinate the limited post of side to realize the spacing mode of lower unblock, accordingly, arranges another limited post can realize unlocking spacing function in the appropriate location of drag-line 11 opposite side.
Those skilled in the art can design multi-form binding clasp completely, and the method and structure locking, unlock.
Can be found out by embodiment 1 and 2, the invention has the beneficial effects as follows, on common electric bicycle basis, do not need to increase engine installation and can realize function downstairs, and do not have electron steering completely, device is simple, reliability is high, and cost is low.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all, any amendment, improvement etc. done, all should be included within protection scope of the present invention.
