Operation and the function of first embodiment are described below.
When electric bicycle 20 charging, then this electric bicycle 20 is parked in the lugs 10 with forward posture.At this moment, the front-wheel 21 of electric bicycle 20 is inserted between the guide rail 11, front fork 22 is guided to suitable posture, and the electric connector 40 that is subjected on this front fork 22 is coupled in the power supply connector 30.Under this confined state, the front end face that is subjected to the inner core member 45 of chipware device 43 of electric connector 40 and two outer chipwares 46 is near the inner core member 35 of the chipware device 33 of power supply connector 30 and the front end face of two outer chipwares 36.In addition, primary coil 32 and secondary coil 42 are provided with coaxially to each other.In addition, be subjected to the situation of two ferromagnetic element 49 sd sos of electric connector 40: two permanent magnets 39 that ferromagnetic element 49 respectively can inductive power supply connector 30.Utilize the magnetic pull between permanent magnet 39 and the ferromagnetic element 49 that two connectors 30 and 40 are maintained confined state.
When two connectors 30 and 40 are fitted together, have an assembling sense switch (not shown) to detect this assembling situation, by one be arranged on the supply unit 14 the inverter (not shown) for the power supply connector 30 primary coil 32 high frequency electric source is provided.Therefore, produce by the chipware device 33 of two connectors 30 and 40 and 43 magnetic field.Specifically, the magnetic field of above-mentioned generation by a inner core member 35 by power supply connector 30, be subjected to electric connector 40 inner core member 45, be subjected to interconnecting part 47, formed by two outer chipwares 46 of electric connector 40, two outer chipwares 36 of power supply connector 30 and the magnetic circuit that interconnects part 37 of the connector 30 of powering of electric connector 40.Like this, in secondary coil 42, be produced as the induced current of battery 24 chargings of electric bicycle 20.
In this embodiment, being arranged on each chipware device 33 on coil 32,42 neighborings and 43 outer chipware 36,46 is cylindrical.Adopt this structure, just have following advantage.
If an outer chipware (not shown) is a cast pillar shape, then reduce the diameter of outer chipware by the cross-sectional area (cross-sectional area of magnetic circuit) that reduces outer chipware as far as possible, thereby tube wall (diametric size) is reduced, and the minimizing of the diameter of inner core member (not shown) is followed in the minimizing in outer chipware cross section.But, because chipware makes through sintering, so the restriction of size has caused influence to the minimizing of thickness.Thereby even the diameter of inner core member has reduced, but the pipe of outer chipware will keep bigger thickness inevitably.Microminiaturization is restricted.
On the other hand, in the present embodiment, outer chipware 36,46 is cylindrical, and the round diameter of the cross section of the outer chipware 36,46 of each of this embodiment is greater than the thickness of the identical outer chipware of cast pillar of cross section.Therefore, the outer chipware 36,46 of this embodiment is compared with the outer chipware of cast pillar when reducing cross section, and the restriction that is subjected to sintering is little.In other words, when the diameter of the cross section of chipware 36,46 outside each of this embodiment was arranged to identical size with the thickness of the outer chipware of cast pillar, this was of a size of the limiting value of sintering processing, the cross section of the outer chipware 36,46 of this embodiment is less than the cross section of the outer chipware of cast pillar.Therefore, in this embodiment, when the diameter of inner core member 35,45 reduced, the cross section of each outer chipware 36,46 (cross section of magnetic circuit) reduced with the minimizing of inner core member 35,45 diameters, thereby can realize the miniaturization Design of chipware device 33,43.So, can make whole connector make miniature connector.Simultaneously, because small design can make weight saving.
The space that requirement will be installed cast pillar coil 32,42 is arranged between inner core member 35,45 and the outer chipware 36,46.No matter the position of outer chipware 36,46 how, this interval remains constant.Therefore, if outer chipware is arranged in the left and right sides of inner core member, or outer chipware is arranged in the upper and lower sides of inner core member, then connector just increases along the size of left and right directions or above-below direction.Otherwise, in the present embodiment, two outer chipwares 36,46 are arranged that by diagonal positions these two positions tilt with respect to inner core member 35,45.Therefore, connector just can keep smaller value along the size of left and right directions and size along the vertical direction, thereby realizes the design of integral miniaturization.
For example, when respectively outer chipware being arranged in the left and right sides, and when respectively permanent magnet being arranged in the both sides up and down of each outer chipware, the residing position of permanent magnet just is distributed on four points.Therefore, four permanent magnets being set just makes number of components increase.Otherwise, in the present embodiment, two outer chipwares 36,46 are pressed diagonal arrange.According to this layout, bigger dead sector can be fixed on two diagonal positions that outer chipware 36,46 is not installed, the ferromagnetic element 49 with two permanent magnets 39 and two surface areas big (being that magnetic pull is big) is arranged on big dead sector respectively.According to this layout, just can reduce the quantity of permanent magnet 39, and can not reduce permanent magnet 39 magnetic pull.
On the installed surface ( antetheca 31F and 41F) of two connectors 30 and 40, the magnetic pull that permanent magnet 39 produces is the strongest on the line that connects these two permanent magnets 39.So, if connecting the line of the outer chipware of each chipware device does not intersect with the line that is connected permanent magnet, then along the vertical direction or the external force of left and right directions effect impose on when being subjected to electric connector, then worry to be subjected to electric connector near the line that connects permanent magnet, to rock with respect to the power supply connector, and with its disengagement.But in the present embodiment, connect the diagonal of permanent magnet 39 and chipware 36 outside two, the diagonal that extends between 46 intersects, two outer chipwares 36, the diagonal that extends between 46 is by being positioned at the inner core member 35 on inner core member 35,45 axis, two positions of 45, two outer chipware 36 adjacent outer chipwares 46, these two positions are in the both sides of the line that connects two permanent magnets 39.So, being subjected on the electric connector 40 even affact along the vertical direction or along the external force of left and right directions, this also can not rocked near the line that connects permanent magnet 39 by electric connector 40, and two connectors 30 and 40 can maintain rigging position reliably.
