Moreover, charging device 14 can also include a travel mechanism 34, it is electrically connected on controller 30, controller 30 is used for according to the position of the testing result of testing circuit 26 control travel mechanism 34 mobile charging devices 14, uses the relative distance of 24 of the second electromagnetic induction unit of the first electromagnetic induction unit 20 of adjusting electric supply installation 12 and charging device 14.See also Fig. 3 to Fig. 5, Fig. 3 is that the distance of 205 of two contact jaws of two contact jaws 245 of the utility model preferred embodiment second electromagnetic induction unit 24 and the first electromagnetic induction unit 20 is greater than the schematic diagram of a predeterminable range, Fig. 4 be the distance of 205 of two contact jaws of two contact jaws 245 of the utility model preferred embodiment second electromagnetic induction unit 24 and the first electromagnetic induction unit 20 less than the schematic diagram of this predeterminable range, Fig. 5 is contacted with the schematic diagram of two contact jaws 205 of the first electromagnetic induction unit 20 fully for two contact jaws 245 of the utility model preferred embodiment second electromagnetic induction unit 24.For instance, as shown in Figure 3, when 24 distance is greater than this predeterminable range when the second electromagnetic induction unit of the first electromagnetic induction unit 20 of electric supply installation 12 and charging device 14, testing circuit 26 detects the intensity of this electric power signal of the second electromagnetic induction unit 24 can be less than a preset strength, and make the second electromagnetic induction unit 24 can't sense this sensor signal that the first electromagnetic induction unit 20 is sent effectively, so the controller 30 controls second electromagnetic induction unit 24 of charging device 14 does not transmit this electric power signal to electrical management module 28.At this moment, the controller 30 of charging device 14 can be controlled the position of the Strength Changes mobile charging device 14 of this sensor signal of being sensed travel mechanism 34 foundations, the second electromagnetic induction unit 24, so that the second electromagnetic induction unit 24 of charging device 14 along+directions X near the first electromagnetic induction unit 20, use in the actual induction scope of this sensor signal that is sent the first electromagnetic induction unit 20 that enters electric supply installation 12.As shown in Figure 4, this moment, the second electromagnetic induction unit 24 entered in the actual induction scope of the first electromagnetic induction unit 20 along+directions X, though two contact jaws 245 of the second electromagnetic induction unit 24 do not contact fully with two contact jaws 205 of the first electromagnetic induction unit 20, for example two contact jaws 245 can partly be contacted with two contact jaws 205, or two contact jaw 245 angle that can tilt be contacted with two contact jaws 205 etc., this sensor signal of the sufficient intensity that is sent the first electromagnetic induction unit 20 still can be sensed in the second electromagnetic induction unit 24.The charging device 14 this moment anglec of rotation slightly, as shown in Figure 5, travel mechanism 34 also can revise the position of charging device 14 constantly according to the testing result of testing circuit 26, so that two contact jaws 245 of the second electromagnetic induction unit 24 are contacted with two contact jaws 205 of the first electromagnetic induction unit 20 fully, use the power transmission efficiency that reaches best.
As Fig. 4 and shown in Figure 5, can sense this sensor signal of sufficient intensity when the second electromagnetic induction unit 24, and the intensity of this electric power signal that testing circuit 26 detects the second electromagnetic induction unit 24 is during greater than this preset strength, meaning is that the distance of 24 of the second electromagnetic induction unit of the first electromagnetic induction unit 20 of electric supply installation 12 and charging device 14 is less than this predeterminable range, so the second electromagnetic induction unit 24 can be sensed this sensor signal that the first electromagnetic induction unit 20 is sent effectively, and this sensor signal is converted to this electric power signal of sufficient intensity.At this moment, the controller 30 of charging device 14 is used for controlling the second electromagnetic induction unit 24 will transfer to electrical management module 28 from this electric power signal of this sensor signal conversion, use and charge.That is to say that charging device 14 can carry out charging procedure on the electric supply installation 12 or under the situation that is positioned accurately on the electric supply installation 12 shown in Figure 5 in shown in Figure 4 being positioned haply, and promote the convenience of operation.After the electrical management module 28 of charging device 14 was finished charging procedure, travel mechanism 34 can move apart the supply district of electric supply installation 12 with charging device 14 along-directions X (or other any direction), to carry out next operation sequence.
See also Fig. 6 and Fig. 7, this sensor signal Strength Changes that Fig. 6 is responded to for the utility model preferred embodiment second electromagnetic induction unit 24 is with respect to the change curve schematic diagram of the second electromagnetic induction unit, 24 change in location.Fig. 7 is the slope schematic diagram of the utility model preferred embodiment change curve shown in Figure 6.When the controller 30 of charging device 14 is selected predetermined directions (+directions X) to control travel mechanism's 34 past these predetermined directions (+directions X) when advancing, the intensity of this sensor signal that the second electromagnetic induction unit 24 is responded to can change along with the position of the second electromagnetic induction unit 24, and meaning promptly changes and changes according to 20 distances in the second electromagnetic induction unit 24 and the first electromagnetic induction unit.For instance, as shown in Figure 6, when the position of the second electromagnetic induction unit 24 was P0 (position as shown in Figure 3), this sensor signal intensity that the second electromagnetic induction unit 24 is responded to was I0; When the position of the second electromagnetic induction unit 24 was P1 (position as shown in Figure 4), this sensor signal intensity that the second electromagnetic induction unit 24 is responded to was I1; When the position of the second electromagnetic induction unit 24 was P2 (position as shown in Figure 5), this sensor signal intensity that the second electromagnetic induction unit 24 is responded to was I2.Therefore, when advancing along this predetermined direction (+directions X) in the second electromagnetic induction unit 24, so that the position of the second electromagnetic induction unit 24 is along P0, P1, change with P2, use moving closer to the first electromagnetic induction unit 20, and this sensor signal intensity that the second electromagnetic induction unit 24 is responded to is from I0, strengthens in regular turn through I1, to I2.At this moment, the Strength Changes amount of this sensor signal that the second electromagnetic induction unit 24 is responded to respect to the slope of the change curve of the location variation of the second electromagnetic induction unit 24 on the occasion of, as shown in Figure 7, so controller 30 can judge that the direct of travel of charging device 14 is the direction near electric supply installation 12 by this positive slope value, travel mechanism 34 continues to advance with control.Relatively, when the position of the second electromagnetic induction unit 24 when P2 moves to P3, this sensor signal intensity that the second electromagnetic induction unit 24 is responded to is decremented to I3 from I2, and controller 30 also can judge that the direct of travel of charging device 14 is the direction away from electric supply installation 12 by the negative slope value of this change curve.
This slope value of calculating gained when controller 30 is when just changeing negative, block as Fig. 6 and dotted line shown in Figure 7 mark, controller 30 can judge that the second electromagnetic induction unit 24 has been positioned at the position near the first electromagnetic induction unit 20 by the variation of this slope value, and in the running that stops travel mechanism 34 with the time.At this moment, if testing circuit 26 detects the intensity of this electric power signal of the second electromagnetic induction unit 24 greater than this preset strength, meaning is the best supply district that charging device 14 has been positioned at electric supply installation 12, and then induction type charging system 10 can begin to carry out charging procedure.Otherwise, if testing circuit 26 detects the intensity of this electric power signal of the second electromagnetic induction unit 24 less than this preset strength, meaning does not promptly have the direct of travel mistake that electric installation 14 enters the supply district of electric supply installation 12, so controller 30 need restart travel mechanism 34 to adjust the direct of travel of charging device 14, the position of using adjustment charging device 14 is to enter the best supply district of electric supply installation 12.
Moreover, electric supply installation 12 can be designed to the contact charging with charging device 14, meaning is promptly when the second electromagnetic induction unit 24 transmits these electric power signals to electrical management module 28, two contact jaws 205 of the first electromagnetic induction unit 20 are that 24 two contact jaws 245 with the second electromagnetic induction unit contact with each other, and use and obtain preferable power transmission efficiency.Or electric supply installation 12 also can be designed to contactless charging with charging device 14, anticipate when promptly the second electromagnetic induction unit, 24 these electric power signals of transmission are to electrical management module 28, two contact jaws 205 of the first electromagnetic induction unit 20 are not contacted with two contact jaws 245 of the second electromagnetic induction unit 24, so that the second electromagnetic induction unit 24 can begin to carry out charging procedure immediately when entering the actual induction scope of this sensor signal that is sent the first electromagnetic induction unit 20.The contact charging technique has higher charge efficiency, contactless charging technique has preferable operation ease, so induction type charging system 10 of the present utility model can be applicable to contact charging technique and contactless charging technique simultaneously, uses the advantage that has both concurrently.
See also Fig. 8, the electric power signal strength that Fig. 8 changes according to sensor signal for the utility model preferred embodiment induction type charging system 10 is to start the flow chart of charging procedure voluntarily.This method includes the following step:
Step 100: this electric power of this first voltage level V1 that the connecting interface 16 reception power supplys 18 of electric supply installation 12 are provided;
Step 102: the drive circuit 22 of electric supply installation 12 utilizes the first electromagnetic induction unit 20 of this driven by power electric supply installation 12 that connecting interface 16 transmitted to send this sensor signal;
Step 104: this sensor signal that 24 inductions, the first electromagnetic induction unit 20, the second electromagnetic induction unit of charging device 14 is sent;
Step 106: the second electromagnetic induction unit 24 is converted to this sensor signal this electric power signal that has less than this second voltage level V2 of this first voltage level V1;
Step 108: whether the testing circuit 26 of charging device 14 detects the intensity of this electric power signal of the second electromagnetic induction unit 24 greater than this preset strength, if not, and execution in step 110; If then execution in step 114;
Step 110: the controller 30 controls second electromagnetic induction unit 24 of charging device 14 does not transmit this electric power signal to electrical management module 28;
Step 112: the controller 30 of charging device 14 is according to the position of the testing result control travel mechanism 34 mobile charging devices 14 of testing circuit 26, use the relative distance of 24 of the second electromagnetic induction unit of the first electromagnetic induction unit 20 of adjusting electric supply installation 12 and charging device 14, then get back to step 108;
Step 114: the signal processing circuit 32 of charging device 14 carries out this electric power signal signals such as rectification and filtering to be handled;
Step 116: this electric power signal that the controller 30 control second electromagnetic induction unit, 24 transmission of charging device 14 are handled through signal is to electrical management module 28;
Step 118: electrical management module 28 stores this electric power signal of handling through signal, then execution in step 120;
Step 120: finish.
Be elaborated at above-mentioned step in this.At first, the user is connected to power supply 18 with the connecting interface 16 of electric supply installation 12, use this electric power that receives this first voltage level V1 that power supply 18 provided, wherein power supply 18 can be an external power source, and this electric power that power supply 18 is provided can be 110 volts to 220 volts alternating electromotive force.When electric supply installation 12 by connecting interface 16 after power supply 18 is obtained this electric power, the drive circuit 22 of electric supply installation 12 utilizes the first electromagnetic induction unit 20 of this driven by power electric supply installation 12 to send this sensor signal.Because the first electromagnetic induction unit 20 is made up of first iron core 201 and first induction coil 203, so this sensor signal can be the magnetic induction signal with magnetic flux change, and the magnetic flux change of this magnetic induction signal changes according to the periodicity of the size of this alternating electromotive force that power supply 18 provides and direction.When the first electromagnetic induction unit 20 sent this sensor signal, this sensor signal that the first electromagnetic induction unit 20 is sent can be sensed in the second electromagnetic induction unit 24 of charging device 14.Because the second electromagnetic induction unit 24 is made up of second iron core 241 and second induction coil 243, and this second coil turn of second induction coil 243 is less than this first coil turn of first induction coil 203, so the second electromagnetic induction unit 24 can be converted to this electric power signal that has less than this second voltage level V2 of this first voltage level V1 by this sensor signal that electromagnetic induction effect will be sensed.Wherein, the ratio of this first voltage level V1 and this second voltage level V2 is proportional to the ratio of this second coil turn of this first coil turn of the first electromagnetic induction unit 20 and the second electromagnetic induction unit 24.
Then, the testing circuit 26 of charging device 14 detects the intensity of this electric power signal of the second electromagnetic induction unit 24, for example voltage strength of this electric power signal.The intensity that detects this electric power signal when testing circuit 26 is during less than this preset strength, the hypertelorism that first electromagnetic induction unit 20 of expression electric supply installation 12 and the second electromagnetic induction unit of charging device 14 are 24 makes the second electromagnetic induction unit 24 can't sense this sensor signal that the first electromagnetic induction unit 20 is sent effectively.At this moment, the controller 30 of charging device 14 promptly is used for controlling the second electromagnetic induction unit 24 and does not transmit this electric power signal to electrical management module 28, and the controller 30 of charging device 14 can detect the Strength Changes of this electric power signal and this sensor signal Strength Changes position with respect to the slope value control travel mechanism 34 mobile charging devices 14 of the change curve of the second electromagnetic induction unit, 24 change in location according to testing circuit 26, uses near electric supply installation 12 and enters in effective signal strength scope of this sensor signal of the first electromagnetic induction unit 20.What deserves to be mentioned is that because this sensor signal that the first electromagnetic induction unit 20 is sent is the magnetic induction signal, the second electromagnetic induction unit 24 also can generate corresponding magnetic induction signal.So charging device 14 is during near electric supply installation 12, the first electromagnetic induction unit 20 and 24 of the second electromagnetic induction unit can produce an auxiliary magnetic attraction, travel mechanism 34 can utilize the guiding of this auxiliary magnetic attraction with charging device 14 migration electric supply installations 12, to obtain preferable power transmission efficiency.
In charging device 14 has entered the actual induction scope of electric supply installation 12, and the intensity of this electric power signal that testing circuit 26 detects the second electromagnetic induction unit 24 is during greater than this preset strength, the meaning i.e. second electromagnetic induction unit 24 has entered in effective signal strength scope of this sensor signal of the first electromagnetic induction unit 20, transmits these electric power signals to electrical management module 28 so the controller 30 of charging device 14 promptly is used for controlling the second electromagnetic induction unit 24.Yet, before controller 30 transfers to electrical management module 28 with this electric power signal, the signal processing circuit 32 of charging device 14 can be earlier carries out signals such as rectification or filtering with this electric power signal of the second electromagnetic induction unit 24 to be handled, use this electric power signal of obtaining better quality, and then this electric power signal after signal is handled is transferred to electrical management module 28 to charge.Wherein, signal processing circuit 32 can be one and optionally is provided with, and meaning is that charging device 14 can promptly directly transfer to electrical management module 28 by controller 30 with this electric power signal without the handling procedure of signal processing circuit 32.After charging finishes, the controller 30 controls second electromagnetic induction unit 24 of charging device 14 does not transmit this electric power signal to electrical management module 28, so the suction of should assisting that the first electromagnetic induction unit 20 and the second electromagnetic induction unit are 24 can weaken, so that the travel mechanism 34 of charging device 14 can move apart electric supply installation 12 with charging device 14.
In sum, because two contact jaws 205 of the first electromagnetic induction unit 20 and two contact jaws 245 of the second electromagnetic induction unit 24 are respectively two magnetic poles, so utilize magnetic pole can avoid the accident that causes because of electric leakage or short circuit effectively, and then the function of waterproof can be provided as the induction type charging system 10 of conductive junction point.In addition, in preferred embodiment of the present utility model, two contact jaws 205 of the first electromagnetic induction unit 20 are that two contact jaws 245 with the second electromagnetic induction unit 24 contact with each other, so that induction type charging system 10 has optimal charge efficient.Yet, when two contact jaws 205 of the first electromagnetic induction unit 20 are not contacted with two contact jaws 245 of the second electromagnetic induction unit 24 fully, as long as the second electromagnetic induction unit 24 has been positioned at effective signal strength scope of this sensor signal of the first electromagnetic induction unit 20, this sensor signal of the first electromagnetic induction unit 20 can be sensed in the second electromagnetic induction unit 24, and this sensor signal that will sense is converted to this electric power signal to carry out the program to 28 chargings of electrical management module.Therefore, use magnetic pole not need two magnetic poles of charging device 14 are positioned accurately two magnetic poles of electric supply installation 12 as the induction type charging system 10 of the transmission contact of sensor signal, as long as two magnetic poles of charging device 14 enter electric supply installation 12 the power supply permissible range of two magnetic poles in can charge, so can promote the operation ease of induction type charging system 10 widely.
