The bottom cover 12 is further arranged with a plurality of power generation device snaps 122, each of the power generation device snaps 122 being capable of securing each of the power generation devices 20. Preferably, in the preferred embodiment of the present invention, each of the power generation devices 20 is fixed by four power generation device buckles 122 of the bottom cover 12. The bottom cover 12 further has a plurality of bottom cover fulcrums 123, and each of the bottom cover fulcrums 123 is coupled to each of the key shafts 1111, thereby supporting the top cover 11.
It should be noted that the box 10 further includes an outer frame 13. The outer frame 13 can reinforce the connection between the top cover 11 and the bottom cover 12.
In this preferred embodiment of the present invention, as shown in fig. 2 and 3, the bluetooth controller with electric power generation means is provided with four of the electric power generation means 20, each arranged in parallel. Correspondingly, the top cover 11 includes four keys 111. It is worth mentioning that in the prior art, in a size space of a standard wall switch with a width of 86mm, the number of keys (i.e. the number of power generation devices) of the existing seesaw type self-power generation wireless switch is not more than 3; because the power plant is bulky and is limited by its shape, it does not accommodate too much power plant in the dimensional width of a 86mm standard switch. However, in the present invention, since each of the power generation devices 20 has a small size, 4 or more power generation devices may be arranged in one bluetooth controller with an electric power generation device, and each of the power generation devices 20 may be operated individually or cooperatively.
It should be noted that the bluetooth controller with an electric energy generating device of the present invention has a plurality of power generating devices 20, and can control a plurality of electrical devices in a multi-channel manner, thereby reducing the cost and increasing the practicability.
Further, as shown in fig. 4 to 14, a perspective view of the power generation device 20 according to this embodiment of the present invention is shown. The power generating device 20 includes a magnetic conductive cavity 21, a permanent magnet 223 and a coil 23. The coil 23 is disposed in a magnetic conducting cavity 210 formed by the magnetic conducting cavity 21, and the permanent magnet 223 is disposed in the magnetic conducting cavity 210.
More specifically, the magnetic cavity 21 includes a magnetic enclosure 211 and a center pillar 212, the magnetic enclosure 211 further includes a top magnetic closure 2115 and a bottom magnetic closure 2116, and the top magnetic closure 2115 and the bottom magnetic closure 2116 form the magnetic cavity 210. The magnetic conductive cavity 210 can accommodate the permanent magnet 223, the center pillar 212, and the coil 23. That is, the coil 23 is disposed inside the magnetic conductive housing 211, i.e., inside the magnetic conductive chamber 210, and is disposed around the center pillar 212.
Each of the power generation devices 20 further includes a bobbin 26, and the coil 23 is wound around the outer circumference of the bobbin 26. In this preferred embodiment of the present invention, the bobbin 26, the coil 23 and the center post 212 can be defined as a coil assembly, and the coil assembly and the permanent magnet 223 are enclosed inside by the magnetic conductive cavity 21 formed by the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116 to form a whole. Wherein, the center pillar 212 can swing after being stressed. In the preferred embodiment illustrated in the drawings, the coil 23 is disposed on the bobbin 26, and the bobbin 26 is disposed around the center leg 212 such that the coil 23 surrounds the center leg 212. It is understood that, in another modified embodiment, the coil 23 may be directly wound around the center pillar 212, and the center pillar 212 may be pivotally driven by using a support structure. Preferably, the number of turns of the coil 23 is 100 to 2000 turns.
It should be noted that fig. 6 to 8 are shown, wherein fig. 7 is a sectional view taken along a-a of fig. 6, and fig. 8 is a sectional view taken along B-B of fig. 6. In this embodiment of the present invention, a magnetic gap 2118 is formed between two side edges of the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116, and the permanent magnet 223 is clamped between the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116. The center post 212 is held by the bobbin 26 and then sleeved by the coil 23. Because coil skeleton 26 is including a top coil skeleton 261, a bottom coil skeleton 262 and a pair of skeleton fulcrum 263, skeleton fulcrum 263 set up in top coil skeleton 261 with between the bottom coil skeleton 262 support, center pillar 212 can use skeleton fulcrum 263 swings between the magnetic gap as the swing fulcrum, alternately with top magnetism closing cap 2115 with the edge conflict of bottom magnetism closing cap 2116, thereby make the magnetic field direction that passes through in the coil changes, and then produces induced current.
In order to maintain the relative sealing performance of the magnetic conductive cavity 21, a magnetic gap 2118 is formed between two side edges of the top magnetic sealing cover 2115 and the bottom magnetic sealing cover 2116. More specifically, as shown in fig. 12-14, the rim of the top magnetic closure cap 2115 extends downward to form two top center post abutment ends 21151, 21152 and two top closure abutment ends 21153, 21154. Accordingly, the bottom magnetic closure cap 2116 extends upwardly to form two bottom center post abutment ends 21161, 21162 and two bottom closure abutment ends 21163, 21164. Preferably, the top magnetic closing lid 2115 and the bottom magnetic closing lid 2116 are bent at 90 degrees to form 4 abutting ends abutting against the center pillar 212. The two top closed abutting ends 21153 and 21154 are attached to one pole of the permanent magnet 223, and the two bottom closed abutting ends 21163 and 21164 are attached to the other pole of the permanent magnet 223, so that two side walls of the magnetic conduction cavity 21 are formed. The permanent magnets 223 are disposed on the inner sides of the two sealing sidewalls. A gap is left between the top center leg abutment end 21151 and the bottom center leg abutment end 21161, and correspondingly, a gap is left between the top center leg abutment end 21152 and the bottom center leg abutment end 21162, thereby forming a magnetic gap 2118 between the side edges of the top magnetic closure 2115 and the bottom magnetic closure 2116, respectively.
Each of the power generation devices 20
Is connected to the end of the center pillar 212. For example, in this embodiment of the present invention, two driving members 24 are respectively connected to two ends of the center pillar 212 extending out of the magnetic conductive cavity 21, and are respectively implemented as a spring. Thus, when the driving member 24 is forced to swing, the two ends of the center post 212 are driven to swing up and down, and alternately contact the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116. To achieve a more stable swing of the center pillar 212, more specifically, the pair of frame fulcrums 263 includes a top fulcrum 2631 and a bottom fulcrum 2632. The top support point 2631 is disposed at an inner middle position of the top bobbin 261, and the bottom support point 2632 is disposed at an inner middle position of the bottom bobbin 262. Wherein the so-called inner side is defined as the side opposite to the center pillar 212. Thus, in this embodiment of the present invention, the bobbin 26 includes the top bobbin 261 and the bottom bobbin 262, and sandwiches the center leg 212, so that the center leg 212 slightly swings centering on the bobbin fulcrum 263 at the center position of the bobbin 26.
It is understood that the power generation device 20 may have a single driving element 24, and may be implemented as a spring or other elastic element, and the bobbin supporting point 263 may be disposed at an inner middle position or a position deviated from the middle position of the bobbin, or the bobbin supporting point 263 may be disposed at one side of the bobbin and the driving element may be disposed at the other side and may be driven to swing.
It should be noted that after the center post 212 penetrates the bobbin 26, the wire is wound around the bobbin 26 for 100 to 2000 turns to form the coil 23. Then, the two ends of the coil 23 are respectively connected to the two lead posts 264 at the two ends of the coil bobbin 26, so that the power generation device 20 can be conveniently welded to the circuit board 30.
It should be noted that the center pillar 212 may slightly swing between the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116 with the top supporting point 2631 and the bottom supporting point 2632 of the bobbin 26 as an axis. Wherein, preferably, the range of the swing angle can be 1-30 degrees in value. Preferably, the swing gap of the center pillar 212 between the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116 ranges from 0.1mm to 8mm in value.
It should be noted that the power generation device 20 further includes a plurality of connecting members, such as rivets 216, each of the rivets 216 can connect two ends of the center pillar 212 with two of the driving members 24, so that when the driving members 24 swing under a force, the center pillar 212 can be driven by the driving members 24 to slightly swing.
The working principle of the power generation device 20 is disclosed as shown in fig. 13 to 14. Wherein the dotted lines with arrows in the figure indicate the direction of the magnetic induction lines. As shown in fig. 13, in the assumed initial state, the abutment state between the center pillar 212 and the upper bottom magnetic closing covers 2115 and 2116 is: the center leg 212 is abutted with the top center leg abutment end 21152 on the left side, and the center leg 212 is abutted with the bottom center leg abutment end 21161 on the right side. At this time, as shown by the arrow in fig. 13, the magnetic induction line passes through the coil 23 from left to right, the center leg 212 is kept in a stationary state, and no induced current is generated in the coil 23.
Further, as shown in fig. 14, when the driver 24 is pushed in the direction of the arrow and the driver 24 on the left side is pressed, the abutment state of the center pillar 212 with the top and bottom magnetic closing covers 2115 and 2116 is changed, and the abutment state in fig. 14 is: the left side of the center leg 212 abuts the bottom center leg abutment end 21162 and the right side of the center leg 212 abuts the top center leg abutment end 21151. As the direction of the arrow, the direction of the magnetic induction line changes from right to left and passes through the coil 23, the direction of the magnetic induction line is reversed, and the coil 23 generates induced current in the process of sudden change of the magnetic induction line. The driver 24 here functions to store potential energy, accelerate the swing speed of the center pillar 212, and thus increase the induced energy.
It should be noted that, in the preferred embodiment of the present invention, when the magnetic conductive cavity 21 of the power generation device 20 is implemented as the structure of the semi-closed state of the top and bottom magnetic covers 2115 and 2116 in the present embodiment, the influence of the magnetic induction lines on the coil 23 is the largest. And the magnetic leakage of the structure is small, so that the generating efficiency of the high-power generating device is relatively high, and the energy is strong.
Accordingly, the self-generating method in this preferred embodiment of the present invention comprises the steps of:
the center pillar 212 is pivotally moved with respect to a pair of opposite bobbin supports 2631 and 2632 of the bobbin 26, and both ends of the center pillar 212 alternately contact the top and bottom magnetic closing caps 2115 and 2116 at both ends of the permanent magnet 223, respectively, so that the direction of a magnetic induction line passing through the coil 23 surrounding the bobbin 26 is changed to generate an induced current in the coil 23.
It is understood that the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116 sandwich the permanent magnet piece 223 and have a space at both sides to form the magnetic gap 2118, the center pillar 212 is inclined when reaching the two extreme positions, and one end contacts the bottom magnetic closing cover 2116 and the other end contacts the top magnetic closing cover 2115; while the one end contacts the top magnetic closure 2115, the opposite end contacts the bottom magnetic closure 2116.
The driving member 24 is connected to both ends of the center pillar 212, so that the power generation method further includes the steps of: driving one of the driving members 24 to pivot the center leg 212 to change the direction of the magnetic induction line passing through the coil 23 to generate a primary induced current in the coil 23; and driving the other of the driving members 24 to pivot the center leg 212 in the opposite direction to change the direction of the magnetic induction line passing through the coil 23 to generate another induced current in the coil 23.
It will be appreciated that in this embodiment, the coil 23 and the permanent magnet piece 223 are located in the magnetic conductive cavity 210 formed by the top magnetic closure 2115 and the bottom magnetic closure 2116, and the top magnetic closure 2115 and the bottom magnetic closure 2116 are located on either side of the permanent magnet piece 223 to form two magnetic conductive pieces.
Fig. 9 to 11 show the specific operation of the bluetooth controller with an electric energy generating device according to the present invention. Fig. 10 is a hypothetical initial state, and fig. 11 is a state after the key 111 is pressed. Specifically, as in the initial state of fig. 10, the key 111 is in a state where the left side is high and the right side is low. That is, the left button protrusions 1112 are in contact with the left driving member 24, and the right button protrusions 1112 are in contact with the right driving member 24. Since the permanent magnet 223 is sandwiched between the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116, and the top magnetic closing cover 2115 and the bottom magnetic closing cover 2116 have a magnetic conductive function, the left side of the center pillar 212 is attracted to the top center pillar contact end 21152, and the right side of the center pillar 212 is attracted to the bottom center pillar contact end 21161.
At this time, the magnetic induction line passes through the coil 23 from left to right, and since this is a state of being stationary for a long time, no current is induced in the coil 23 at this time.
Further, when the left end of the key 111 is pressed, the key 111 starts to rotate toward the bottom cover 12. That is, the left button protrusions 1112 press down the left driving member 24, and the right button protrusions 1112 lift up to release the right space. Therefore, under the action of the two key protrusions 1112, the left driving member 24 begins to deform and store potential energy.
When the stroke of button 11 reaches about 2mm, the power of driving piece 24 deformation is greater than top magnetism closing cap 2115 with end magnetism closing cap 2116's actuation, consequently, center pillar 212 takes place quick displacement, by original the left side of center pillar 212 with top center pillar butt end 21152 actuation, the right side of center pillar 212 with end center pillar butt end 21161 actuation becomes in the twinkling of an eye in about 1 ms's time the left side of center pillar 212 with end center pillar butt end 21162 actuation, the right side of center pillar 212 with top center pillar butt end 21151 actuation. The rapid oscillation of the newel 212 causes the direction of the magnetic induction line passing through the coil 23 to abruptly change within 1 ms. Thus, the direction of the magnetic induction lines is changed from "left to right" in fig. 10 to "right to left" in fig. 11. An electrical pulse of 18V is generated in the coil 23 and maintained for a period of 1 ms.
After the process is finished, pressing the opposite end of the key 111 will repeat the above-mentioned operation process, so that after the two ends of the key 111 are stressed, the coil 23 of the power generation device 20 will generate primary electric energy under the driving of the key 111. In a cycle, each of the keys 111 generates an electrical pulse each time it is pressed.
It should be noted that the peripheral side of the bottom cover 12 further includes at least one stop edge 124, so that the two ends of the key 111 can alternatively abut against the stop edge 124. The height of the stop edge 124 can be preset, so that the pressing force of the invention is extremely light, the pressing stroke is small, and no noise exists.
The above is the principle of mechanical operation, and as shown in fig. 15 to 18, the whole operation process is disclosed in detail in conjunction with the circuit part.
As shown in fig. 15, since a plurality of power generating devices 20 can be arranged in the present invention, each power generating device 20 needs to be connected in parallel to supply power to the buck-boost circuit, and therefore, an isolation bridge 81 is needed to isolate each coil 23 to prevent a short circuit of the power supply.
In the circuit shown in fig. 15 there are four identical power generating circuits, one for each set of coils 23, for generating the induced current. Taking circuit a as an example, two lead terminals of the coil 23 are connected to the input terminals in1 and in2 of the isolation bridge stack 81; the two lead terminals of the coil 23 are also connected to the anodes of two diodes 821, 822, respectively; the cathodes of the diodes 821, 822 are then respectively connected to one ends of a capacitor 831, 832 and connected to an input/output (I/O) port of a communication circuit 87 through a resistor 851, 852, respectively, and the other ends of the capacitor 831, 832 are grounded. There is at least one buffer capacitor 84 between the output terminals out + and out-of the isolated bridge stack 81. The output terminals out + and out of the isolation bridge stack 81 are connected to the power input terminal 861 of the buck-boost IC86, and the output terminals of the isolation bridge stack 81 are connected in parallel and to the power input terminal 861 of the buck-boost IC 86. The output 862 of the buck-boost IC86 is connected to a power input of the communication circuit 87.
It should be noted that the communication circuit 87 in this embodiment is a BLE bluetooth circuit.
Specifically, when the button 111 is pressed, 1 time of an electric pulse of about 18V is generated in the coil 23, and when the button 111 is lifted, 1 time of the same electric pulse is generated in the coil 23, except that the polarities of the two electric pulses output at the two ends of the coil 23 are different.
Therefore, in order to utilize the key 111 by two pulses, i.e. pressing and tilting, the isolation bridge 81 also has a commutation function, i.e. two currents with different directions are integrated into a current with the same direction by the unidirectional conduction characteristic of the diode, and the integrated circuit (integrated circuit) 86 can be powered once no matter the key is pressed or lifted.
When the key 111 is pressed, an electrical pulse of 18V is generated in the coil 23 (waveforms are shown as waveforms 91 and 92), assuming that the in1 terminal is a positive pulse and the in2 terminal is a negative pulse. The electric pulse is divided into two paths, one path is used as a power supply of the circuit, the other path is used as a signal pulse and is transmitted to an I/O port of the communication circuit 87, an internal MCU is used as key information processing, the state of the key can be judged to be pressed or lifted by detecting the pulses at two ends of the coil 23, and under the condition that a control system is needed, the control system needs to obtain the state of the key, so the circuit can provide the function.
One of the paths is a step-up/step-down circuit as a power supply:
an electrical pulse of 18V will power the buck-boost IC86 through the isolated bridge stack 81.
Since the limit value of the voltage at the input 861 of the buck-boost IC86 used in this embodiment is 10V, in order to ensure that the buck-boost IC86 is not damaged by the 18V electrical pulse, the buffer capacitor 84 must be connected to the power input 861 of the buck-boost IC 86. It will be appreciated by those skilled in the art that this limit of 10V in the preferred embodiment is merely exemplary, and that there are other different specifications to which the present invention is not limited.
Since the electric pulse with the buffer capacitor 84 and 18V is buffered by the capacitor (the waveform of the electric energy generated after the capacitor buffering is the waveform 95 in fig. 15), the peak voltage will be 6V, and the buck-boost IC86 can work for a long time without loss. It will be understood by those skilled in the art that the peak voltage is not limited to 6V, and can be adjusted according to the specification of the buffer capacitor used, and the invention is not limited thereto.
It should be noted that the buck-boost IC86 may be a DC-DC boost switching power supply, a DC-DC buck switching power supply, or a single voltage transformation device.
In the circuit of this path, the buck-boost IC86 outputs 2V to power the communication circuit.
The other path is signal pulse:
the positive electric pulse (waveform 91, which is a waveform diagram of voltage generated by pressing the key twice, waveforms 91 and 92 are the same, and the polarity of the pulse is opposite) is charged to the capacitor 832 from the in1 end through the diode 822, and the existence time of the pulse can be prolonged in the charging and discharging process, so that the MCU can accurately capture the pulse.
The voltage amplitude is about 15V (waveform 94), so that it is necessary to reduce the current through the resistor 852 and then transmit the signal to the I/O interface 8722 of the bluetooth communication unit 87.
Similarly, when the button 111 is tilted, an electrical pulse of 18V is generated in the coil 23, and at this time, the in1 end is a negative pulse, and the in2 end is a positive pulse.
The electrical pulse charges the capacitor 831 through the diode 821, and provides a signal detection level for the other I/O port 8721 of the bluetooth communication unit 87 after being current-limited and voltage-reduced through the resistor 851.
The communication circuit 87 is powered on and the I/O port 872 is inputted with a control signal, so that the communication circuit 87 implemented as a bluetooth communication circuit repeatedly broadcasts in multiple channels in a time of 5ms according to its protocol, and transmits control information of the I/O port 872 as a broadcast signal.
It should be noted that any device with bluetooth function can configure the information with APP after receiving the broadcast information of the bluetooth controller with electric energy generation device of the present invention, and can be used to control electric lamps, air conditioners, electric appliances, etc., and the application is very wide.
It should be noted that the present invention has multiple channels, uses frequency hopping to transmit data, transmits data from 2402MHZ to 2480MHZ in a wide frequency band, and can use another channel to transmit signals when one channel is blocked, thereby solving the problem that single frequency communication is easily interfered.
It should be noted that in this embodiment of the present invention, the communication circuit 87 uses the bluetooth communication unit 87, and BLE bluetooth technology is used. It will be understood by those skilled in the art that the communication circuit 87 may also use a wireless transceiver circuit with an MCU or a wireless transceiver circuit with a coding circuit, so that communication can be in the form of electromagnetic waves or communication can be in the form of light waves. That is, when the communication circuit 87 uses a transceiver circuit with MCU or a transceiver circuit with encoder circuit, the output 862 of the buck/boost IC is connected to the power input of a transceiver unit with MCU or to the power input of a transceiver unit with encoder circuit.
It is worth mentioning that when light waves are used for communication, the coding chip or the MCU can be directly used to drive the infrared diode, the laser diode and the visible light emitting tube to transmit and receive signals.
It is worth mentioning that the data volume transmitted in the present invention at the same time can be up to 20 times of the prior art, and the data can be encrypted and controlled more safely and effectively. Therefore, various problems generated in the application of the existing self-generating high-frequency transmitter technology can be solved.
FIG. 16 is a simplified circuit diagram of another embodiment of the present invention. May be adapted to a controller arranged with a single said power generation means 20. Specifically, one end of the coil 23 is connected to the cathode 8611A of a buck-boost IC86A, and the other end is connected to the anode 8612A of the buck-boost IC86A through a diode 82A. With the provision of buffer capacitor 84A, waveform 91A (the waveform of the electrical pulse of the two toggles) is buffered as waveform 95A. The output 862A of the buck-boost IC86A is connected to the power input of the communication circuit 87A. Therefore, in this circuit, when the key 111 is pressed and lifted, the power is supplied to the buck-boost IC86A only once. In this embodiment of the present invention, the present invention can be applied to a calling system such as a doorbell.
It should be noted that the diode 82A in the above embodiment may be reversely mounted on the terminal connected to the negative terminal of the buck-boost IC86A in other embodiments, and the invention is not limited thereto.
FIG. 17 is a simplified circuit diagram of another embodiment of the present invention. The two lead terminals of the coil 23 are connected to a power commutating bridge stack 81B. The two terminals of the power commutating bridge stack 81B are connected in parallel and to a power input 861B of a buck-boost IC 86B. The output 862B of the buck-boost IC86B is connected to the power input of the communication circuit 87B. There is at least one buffer capacitor 84B between the output terminals of the power commutating bridge stack 81B. Due to the setting of the buffer capacitor 84B, the waveform 91B (the waveform of the electrical pulse of the two toggles) is buffered as waveform 95B. In contrast to the embodiment of fig. 16, the power commutating bridge stack 81B is connected to both ends of the coil 23. When the key 111 is pressed and tilted, once electric energy can be generated, and the key can be used in some simple switches.
It should be noted that, in the three embodiments of fig. 15 to 17, the communication circuits 87,87A and 87B are bluetooth communication circuits for transmitting and receiving data. The communication unit is not limited to a bluetooth communication circuit. When a wireless transceiver circuit with an MCU or a coding circuit is used, the communication circuits 87,87A and 87B are wireless transceiver circuits with MCUs or wireless transceiver circuits with coding circuits, and may be other communication circuits, which is not limited in the present invention.
It is worth mentioning that when the wireless transceiver circuit with the encoding circuit is adopted, the encoding information is generated by judging the positive pulses at the two ends of the coil 23, and compared with the prior art that the encoding information generated by adopting the conductive rubber contact is more reliable and durable, and is not afraid of acid-base corrosion.
It should be noted that the efficient power generation devices 20 of the present invention are combined, and the number of channels controlled by the user according to the need is freely arranged and combined, so as to improve the utilization efficiency, reduce the utilization cost, and increase the interest of the utilization. Therefore, the invention has wide application space and wide application prospect.
