Description
Technical field
Bicycle art is the utility model is related to, particularly a kind of bicycle-driven generation structure.
Background technology
Bicycle for people go off daily bring conveniently, in order that convenience and utilize resource, many bicycles
Self-generating device is installed, powered to car light etc..
Self-generating device is mostly the hub generator installed in front-wheel or rear frame portion at present, is carried out certainly by vehicle wheel rotation
Generate electricity.But the hub generator for being mounted in front wheel positions is being inserted from the rounded axletree both ends in the outstanding section of hub shell
In the mounting groove of the U-shaped of bicycle front fork, and nut is screwed into the threaded portion of axletree to be arranged on bicycle.Also,
When on front fork, toothed packing ring is loaded between nut and front fork, car is pruned using the tooth of packing ring when tightening nut
The covering with paint of frame and locally turn on and be grounded with vehicle frame.Also, by being grounded the ground wire of front car light side and vehicle frame electrical connection.
However, in the occasion of this chassis ground for making bicycle with toothed packing ring, the nut for installing hub shell is twisted
Must be not tight, if the covering with paint of vehicle frame is talked about thicker, even if the covering with paint of vehicle frame can not be poked by tightening nut collar, so as to exist not
Can be reliably grounded, it is impossible to the problem of being powered to front car light.
Utility model content
A kind of situation of the purpose of this utility model aiming at above-mentioned prior art, it is proposed that bicycle-driven generation structure.
The purpose of this utility model is achieved through the following technical solutions：A kind of bicycle-driven generation structure, including car
Axle, inner bearing, outer bearing, in addition to stator, power coil and permanent magnet and be fixedly mounted on the stator (1) it is outside in
Beaming roller (8)；The permanent magnet (4) is fixed in axletree (5), the internal fixed power coil (2) of the stator (1), institute
State power coil (2) be enclosed on axletree (5) and with the position correspondence of permanent magnet (4).
Further, described axletree outer wall both ends installation inner bearing and outer bearing, the permanent magnet are fixed on axletree
Centre position.
Further, described axletree is connected by screw with crank, and the crank reconnects pedal.
Further, described permanent magnet is arranged with multiple magnetic poles being alternately arranged in the circumferential.
Further, described permanent magnet rotates together with axletree.
The beneficial effects of the utility model：Generating mechanism is arranged on axletree position, the axletree of power coil same position
Place is fixed with multiple permanent magnets, and so formation adjacent polarity is opposite is uniformly distributed, and pedal moves by crank handle turns axletree,
Formation magnetic field magnetic line is mutually cut with power coil, and coil produces electromotive force so as to reach the purpose of generating.It is simple in construction, it is fixed
Easily, can reliably generate electricity.The utility model can couple inside vehicle frame axis Kun with vehicle frame does reliable ground.Without extra
Transmission mechanism, capacity usage ratio are high, do not need electric power output when, no friction, undamped torque, also noenergy is consumed,
The fault rate drop of generator is also to be minimum.

Embodiment
A kind of bicycle-driven generation structure of the utility model is described further below in conjunction with the accompanying drawings：The embodiment is only used for
Illustrate the utility model rather than limitation the scope of the utility model, those skilled in the art are to of the present utility model various etc.
The modification of valency form falls within the application appended claims limited range.
As Figure 1-3, a kind of bicycle-driven generation structure, including axletree 5, inner bearing 3-1, outer bearing 3-2, axis Kun
8, in addition to stator 1, power coil 2, permanent magnet 4；The permanent magnet 4 is fixed in axletree 5, and the stator 1 is fixed on axis
Inside roller 8, the power coil 2 is fixed on position corresponding with permanent magnet 4 in stator (1).
The described both ends of axletree 5 installation inner bearing 3-1 and outer bearing 3-2, inner bearing 3-1 and outer bearing 3-2 are installed and consolidated
It is scheduled in bottom bracket axle 8, the axial length of bottom bracket axle 8 is more than or equal to the distance between inner bearing 3-1 and outer bearing 3-2.It is described
Permanent magnet 4 is fixed on the centre position of axletree 5.
Described axletree 5 is connected by screw with crank 6, and the crank 6 reconnects pedal 7.
Described permanent magnet 4 is arranged with multiple magnetic poles being alternately arranged, described permanent magnet 4 and axletree 5 in the circumferential
Rotate together with.
Stator 1 is mounted and fixed in bottom bracket axle 8, power coil 2,2 sets of power coil are installed and fixed inside stator 1
Have certain gap on axletree 5, between both, make axletree 5 rotate when without friction, undamped torque.The correspondence of power coil 2
Fixing permanent magnet 4 at the axletree 5 of same position, permanent magnet 4 are arranged with multiple magnetic poles being alternately arranged, such as 6 in the circumferential
Alternate N, S magnetic pole, so formation adjacent polarity is opposite is uniformly distributed, and pedal 7 drives axletree 5 to move by crank 6, shape
Into mutually cutting for magnetic field magnetic line and power coil 2, power coil 2 produces electromotive force so as to reach the purpose of generating.In axis Kun
Portion couples with vehicle frame does reliable ground.
It is personal that described electrification structure self power generation can be used for dynamo lighting set etc..From the used time, power coil 2 can pass through
Supply lines connection feeder ear carries out power supply, reliable and secure.
