Consult shown in Figure 1ly, electric bicycle 10 of the present invention comprises: a body shell 11, is articulated in the front-wheel 12 and trailing wheel 13, two C shape electromagnet 14 and batteries 16 of body shell 11.Wherein better embodiment is that battery 16 is arranged at body shell 11, and electrically connects the electric energy that provides C shape electromagnet 14 to drive with each C shape electromagnet 14 respectively.
Consult Fig. 1-shown in Figure 2, not not being both of the present invention and conventional art, the trailing wheel 13 of electric bicycle 10 of the present invention is except that having tire 131, wheel frame 132, spoke IS3 and nave boss 134, have most the identical magnetic conductive iron sheets 15 of shape between the inner edge of taking turns frame 132, spoke 133, these magnetic conductive iron sheets 15 are equidistantly or according to the interval of spoke 133 to take turns on the frame 132 along circumferentially being arranged at.In addition, the material of above-mentioned magnetic conductive iron sheet 15 can be used ordinary carbon steel, and carries out antirust processing in its outside.
As shown in Figure 1, two C shape electromagnet 14 are to be arranged at the part that body shell 11 extends back, or are arranged at by the center pillar of top, body shell 11 seats.
Consult shown in Figure 3, wherein above-mentioned C shape electromagnet 14 is made of most sheet silicon steel sheet 141, on silicon steel sheet 141, established the coil 143 of most circles with two stators, 142 folders, when coil 143 conductings, each can form the N utmost point and the S utmost point at the two ends of C shape electromagnet 14, pass through and have the magnetic line of force in the gap 144 of two ends, and produce magnetic force.
Consult shown in Figure 4, when wheel, the interior recess of C shape electromagnet 14, tire 131 and wheel frame 132 are passed through, and the gap 144 of C shape electromagnet 14 can allow each magnetic conductive iron sheet 15 pass through, and makes C shape electromagnet 14 by magnetic attraction magnetic conductive iron sheet 15, drive wheel, electric bicycle is advanced.
Consult Fig. 5-shown in Figure 6, during 14 conductings of C shape electromagnet, can form the N utmost point and the S utmost point at C shape electromagnet 14 two ends, as a magnetic conductive iron sheet 15 during near the gap 144 at C shape electromagnet 14 two ends, the magnetic line of force can form an active force (magnetic force), magnetic conductive iron sheet 15 to be attracted to the position at the magnetic force center of C shape electromagnet 14 as shown in Figure 6, make C shape electromagnet 14 excitations.Therefore, as long as the proper spacing configuration is done in the position of C shape electromagnet I4 and magnetic conductive iron sheet 15, when the trailing wheel of electric bicycle rotated, at least one C shape electromagnet 14 can be by magnetic conductive iron sheet 15 excitations, make C shape electromagnet 14 continue to attract above-mentioned magnetic conductive iron sheet 15, drive wheels is rotated further.
Consult Fig. 7-shown in Figure 10, four rough schematic views for the stressed drive trailing wheel rotation of magnetic conductive iron sheet of the present invention, be only with three C shape electromagnet 14a, 14b, 14c attracts three magnetic conductive iron sheet 15a, 15b, 15c represent in the mode of straight ahead, and the advantageous configurations mode of magnetic conductive iron sheet and C shape electromagnet is provided.
Each magnetic conductive iron sheet 15a, 15b of brushless motor structure of the present invention,
15c to be equidistantly being spaced, and the spacing of the spacing of each magnetic conductive iron sheet 15a, 15b, 15c and each C shape electromagnet 14a, 14b, 14c is non-etc. doubly most.In this embodiment, the ratio of the spacing of the spacing of magnetic conductive iron sheet and C shape electromagnet is 3: 2, and the width of magnetic conductive iron sheet 15a, 15b, 15c is slightly wide than the width of C shape electromagnet 14a, 14b, 14c.This being described as follows each figure respectively:
As shown in Figure 7, when C shape electromagnet 14a energising and C shape electromagnet 14b, during the 14c no power, C shape electromagnet 14a and magnetic conductive iron sheet 15a can produce an active force f, make magnetic conductive iron sheet 15a drive wheel.
As shown in Figure 8, when magnetic conductive iron sheet 15a advances a segment distance during to C shape electromagnet 14a magnetic force center, the power supply of C shape electromagnet 14a can be cut off, and C shape electromagnet 14b is switched on, and makes the magnetic conductive iron sheet 15c can be forward stressed because of magnetic force, drives wheel and advances.
As shown in Figure 9, when magnetic conductive iron sheet 15b advances a segment distance during to C shape electromagnet 14b magnetic force center, the power supply of C shape electromagnet 14b can be cut off, and C shape electromagnet 14c is switched on, and makes the magnetic conductive iron sheet 15c can be forward stressed again because of magnetic force.
At last, as shown in figure 10, when magnetic conductive iron sheet 15c readvances a segment distance during to C shape electromagnet 14c magnetic force center, the power supply of C shape electromagnet 14c can be cut off, C shape electromagnet 14a is switched on, and makes the magnetic conductive iron sheet 15b can be forward stressed because of magnetic force, continues to drive wheel again.So go round and begin again, electric bicycle of the present invention just can continue to advance.
In addition, C shape electromagnet of the present invention can be by the disconnected sensor control of the photoresistance that is arranged at the electromagnet leading edge, when magnetic conductive iron sheet is blocked by the emitted light time of OPTICAL SENSORS the conducting of C shape electromagnet; When magnetic conductive iron sheet passes through, and the receiver of OPTICAL SENSORS receives the emitted light of reflector, then C shape electromagnet is opened circuit, and no longer produces magnetic force.Therefore, brushless motor structure of the present invention can go down according to the illustrated mode continuous action of above-mentioned Fig. 7-Figure 10.
Electric bicycle of the present invention is sayed with the wheel pivot because of the magneticaction arm of force of C shape electromagnet, the arm of force is almost equal in the acting force arm of wheel and frictional ground force, therefore, electric bicycle of the present invention can be with the C shape electromagnet of less power output, just can provide enough torsion, and stronger when making electric bicycle starting and climbing.
Electric bicycle of the present invention can utilize old bicycle structure repacking, and looks user demand two groups or more C shape electromagnet is installed, and when making magneticaction, can have two groups of above C shape electromagnet to act on simultaneously, and bigger torsion output is provided.
In addition, electric bicycle of the present invention does not use permanent magnet, so electric bicycle when action, when if battery electric power is finished using, the user can step on electric bicycle with manpower, its load be not installed much at one this when device, load is increased.
Though the present invention discloses as above with preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this skill person, does a little change and retouching without departing from the spirit and scope of the present invention, all belongs within protection scope of the present invention.
