Accompanying drawing explanation
Fig. 1 is the front view of the universal micro-electric booster for bicycle of the utility model.
Fig. 2 is the partial enlarged drawing of the universal micro-electric booster for bicycle of the utility model.
Detailed description of the invention
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in accompanying drawing 1 and accompanying drawing 2, a kind of universal micro-electric booster for bicycle, comprise power-assisted binary pair 1, supplying cell 2, master control housing 3, movement arm anchor shaft 4, movement arm 5 and external rotor electric machine 6; Described power-assisted binary pair 1 is arranged on the hand of bicycle upper, described supplying cell 2 and master control housing 3 are arranged on the vehicle frame of bicycle respectively, be provided with controller in described master control housing 3, described power-assisted binary pair 1 and supplying cell 2 are electrically connected with the controller in described master control housing 3 respectively by connection lead; One end of described movement arm 5 is connected with the controller in described master control housing 3 by described movement arm anchor shaft 4, the rounded structure of the other end of described movement arm 5, and be coaxially connected with described external rotor electric machine 6, the outer rotor of described external rotor electric machine 6 is connected with the rear tyre of bicycle is tangent when rotating, and is separated when the edge of the outer rotor of described external rotor electric machine 6 does not rotate with the rear tyre of bicycle.
Described external rotor electric machine 6 and the rear tyre synchronous axial system of bicycle, and direction of rotation.
Also comprise stationary fixture 7, the top of described master control housing 3 is fixedly mounted on the bottom of frame of bicycle by described stationary fixture 7, be positioned at the front of bicycle rear tire, be convenient to dismounting the utility model.
Described movement arm 5 and external rotor electric machine 6 are positioned at the bottom dead center position of described movement arm anchor shaft 4.
The outer rotor surface of described external rotor electric machine 6 is provided with friction layer.
When needs power-assisted time, controller is powered by the supplying cell 2 be arranged on bicycle body, electric energy is inputted external rotor electric machine 6, the outer rotor of external rotor electric machine 6 and tire working direction opposite sense are rotated, and make external rotor electric machine 6 produce stronger vibrations when starting by the control method of controller, because external rotor electric machine 6 and movement arm 5 are in the bottom dead center position of movement arm anchor shaft 4 so movement arm 5 is limited to down stroke, so the vibration energy that movement arm 5 and external rotor electric machine 6 produce can only move to top dead point.
Because geometric angle limits, movement arm anchor shaft 4 point of connection is less than the distance (L2) of movement arm anchor shaft 4 point of connection to external rotor electric machine 6 top layer contact point to the distance (L1) on tire top layer.External rotor electric machine 6 friction material is contacted with rear tyre, because when external rotor electric machine 6 operates, the linear resonance surface velocity of outer rotor is greater than surface of tyre linear velocity, outer rotor and the movement arm 5 of external rotor electric machine 6 produce upward reaction force, produce the characteristic that L2 trends towards L1, but because L1 is less than L2, L1 and L2 can't be overlapping, so the outer rotor top layer of generation external rotor electric machine 6 and tire produce the pressure to hind axle center, guarantee that the outer rotor actv. of external rotor electric machine 6 is close to tire top layer, advanced by external rotor electric machine 6 rotary actuation bicycle.
When power-assisted stops, external rotor electric machine 6 loses rotating speed, so tire top layer linear velocity is greater than motor outer rotor top layer linear velocity, external rotor electric machine 6 and movement arm 5 lose the antagonistic force to top dead point, because the reason of gravity falls to bottom dead point, depart from tire top layer, the top layer of the outer rotor of external rotor electric machine 6 and bike tyre about have the separating distance of several millimeters.
Because the utility model is separated completely with tire, any resistance can't be caused to riding, under non helping hand state, as broad as long with common non-boosting mechanism bicycle.
In description of the present utility model, it will be appreciated that, term " on ", " interior ", " one end ", " other end ", " coaxially ", " tangent ", " bottom ", the orientation of the instruction such as " front " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or integral; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals or the interaction relationship of two elements, unless otherwise clear and definite restriction.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
In sum, the utility model actv. alleviates the burden of cyclist, solves existing cycling effort, the problem of Range-dependent cyclist muscle power of riding, and when non helping hand state, reduces the physical demands of cyclist.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description to do; or directly or indirectly use the technical field being attached to other Related products, be all in like manner included in scope of patent protection of the present utility model.
