Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a schematic structural diagram of a control system according to an embodiment of the present disclosure. In the embodiment of the present application, the control system includes a solar panel 2, a rechargeable battery 3, a light emitting element 4, and a control circuit board 1 connected to the solar panel 2, the rechargeable battery 3, and the light emitting element 4, respectively.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a control circuit board 1 according to an embodiment of the present disclosure. The control circuit board 1 includes a printed circuit board 100, and a control chip 101, a first positive interface 102, a first negative interface 103, a second positive interface 104, a second negative interface 105, a third positive interface 106, and a third negative interface 107 disposed on the printed circuit board 100.
The control chip 101 includes a first input pin 1011, a second input pin 1012, a first output pin 1014, and a second output pin 1015. The first positive interface 102, the first negative interface 103, the second positive interface 104, the second negative interface 105, the third positive interface 106, and the third negative interface 107 are disposed outside the region where the control chip 101 is disposed in the printed circuit board 100. For example, the first positive interface 102, the first negative interface 103, the second positive interface 104, the second negative interface 105, the third positive interface 106, and the third negative interface 107 may be disposed at an edge region of the printed circuit board 100 for facilitating wiring.
The first positive interface 102 is used for being connected with the positive electrode of the solar panel 2, and the first negative interface 103 is used for being connected with the negative electrode of the solar panel 2. And the first positive interface 102 is connected to the first input pin 1011.
The second positive interface 104 is adapted to be connected to the positive pole of the rechargeable battery 3 and the second negative interface 105 is adapted to be connected to the negative pole of the rechargeable battery 3. The second positive interface 104 is connected to the first output pin 1014, and the second negative interface 105 is connected to the second output pin 1015 and the first negative interface 103, respectively. For example, in the embodiment of the present application, the first negative interface 103 and the second negative interface 105 may be disposed nearby to facilitate connection between the first negative interface 103 and the second negative interface 105. Optionally, in terms of physical implementation, the functions of the first negative interface 103 and the second negative interface 105 may be implemented by being an entity interface, and at this time, the interface may be connected to the negative electrode of the solar panel 2 or the negative electrode of the rechargeable battery 3. Note that the rechargeable battery 3 in the embodiment of the present application includes, but is not limited to, a lithium battery, a lead-acid battery, a nickel metal hydride battery, and the like.
The third positive interface 106 is used for connecting to the input of the light-emitting element 4, and the third negative interface 107 is used for connecting to the output of the light-emitting element 4. The third positive interface 106 is further connected to the first output pin 1014 and the second positive interface 104 respectively; the third negative interface 107 is also connected to a second input pin 1012. Optionally, in the embodiment of the present application, the first positive interface 102 and the first negative interface 103 may be disposed nearby on the printed circuit board 100, so as to facilitate connection with the solar panel 2; similarly, the second positive interface 104 and the second negative interface 105 may be disposed nearby on the printed circuit board 100, and the third positive interface 106 and the third negative interface 107 may be disposed nearby on the printed circuit board 100.
In this way, when the control chip 101 controls the first input pin 1011 and the first output pin 1014 to be conductive, a closed loop is formed between the solar panel 2 and the rechargeable battery 3, so that the solar panel 2 can charge the rechargeable battery 3. When the control chip 101 controls the second input pin 1012 and the second output pin 1015 to be turned on, a closed loop is formed between the rechargeable battery 3 and the light-emitting element 4, so that the rechargeable battery 3 supplies power to the light-emitting element 4, and the light-emitting element 4 emits light. It should be noted that the light emitting element 4 in the embodiment of the present application refers to an element that emits light by current driving, and includes, but is not limited to, an LED lamp, a tungsten lamp, a fluorescent lamp, and the like.
In the embodiment of the present application, as shown in fig. 3, the control chip 101 may further include a third input pin 1013 dedicated for obtaining the output voltage of the solar cell panel 2, and the third input pin 1013 is directly connected to the first positive interface 102.
Referring to fig. 4, in order to realize the automatic turn-on control of the control chip 101, a voltage gating circuit 1017 may be disposed in the control chip 101, wherein an input terminal of the voltage gating circuit 1017 is connected to the third input pin 1013, and an output terminal thereof is connected to the second output pin 1015, so as to be connected to the anode of the solar cell panel 2 through the third input pin 1013 and the cathode of the solar cell panel 2 through the second output pin 1015. The voltage gating circuit 1017 and the solar panel 2 form a closed loop, so that the voltage output by the solar panel 2 is obtained.
It should be understood that the voltage gating circuit 1017 in the embodiment of the present application functions as follows: when the voltage output by the solar panel 2 is greater than the preset voltage threshold, outputting the current input through the first input pin 1011 through the first output pin 1014 to charge the rechargeable battery 3; and when the voltage output by the solar cell panel 2 is less than or equal to the preset voltage threshold, the second input pin 1012 and the second output pin 1015 are turned on, so that the light-emitting element 4 emits light.
To realize this control function, the voltage gating circuit 1017 in the embodiment of the present application may be implemented as shown in fig. 4, which includes an electromagnet 10171, a conductive structure 10172 that can be attracted by the electromagnet 10171, and a micro spring 10173 disposed between the chip housing and the conductive structure 10172. It should be noted that in the embodiment of the present application, the coil of the electromagnet 10171 is connected to the third input pin 1013 and the second output pin 1015, respectively, so as to receive the current; conductive structure 10172 may be made of a conductive material such as iron that is attracted to electromagnet 10171, or may be a copper wire with a magnetic material attached to the side facing electromagnet 10171. Referring to fig. 4, when the coil of the electromagnet 10171 receives a current greater than a predetermined current threshold (since the current is positively correlated with the voltage, it can also be considered that when the coil receives a voltage greater than a predetermined voltage threshold), the electromagnet 10171 generates magnetism, so that the conductive structure 10172 is attracted between the first input pin 1011 and the first output pin 1014 against the elasticity of the micro spring 10173, thereby making the first input pin 1011 and the first output pin 1014 conductive; similarly, when the voltage received by the coil of the electromagnet 10171 is less than or equal to the predetermined voltage threshold, the conductive structure 10172 falls back between the second input pin 1012 and the second output pin 1015 due to the micro spring 10173, so that the second input pin 1012 and the second output pin 1015 are turned on.
It should be noted that in the embodiment of the present application, the number of turns of the coil, the size of the inner core of the electromagnet 10171, the material, the elastic value of the micro spring 10173, and the like all differ, which causes a difference in the voltage required by the electromagnet 10171 to overcome the elasticity of the micro spring 10173. Therefore, the voltage threshold can be set by controlling the number of coil turns, the size of the inner core of the electromagnet 10171, the material and the elastic value of the micro spring 10173.
It should be understood that the structure of the voltage gating circuit 1017 shown in fig. 4 is only an optional structure in the embodiments of the present application, and does not represent that the voltage gating circuit 1017 can only be implemented by using the structure in the embodiments of the present application. In fact, any structure that can achieve the functions required by the voltage gating circuit 1017 in the embodiments of the present application should fall within the scope of the present application. For example, the voltage gating circuit 1017 in the embodiment of the present application may also be implemented by connecting a common voltage detection circuit and a controlled gating switch.
It should be noted that the voltage output by the solar panel 2 is affected by the intensity of the received light, and when the intensity of the received light is weak, the voltage output by the solar panel is small. In order to prevent the voltage of the solar panel 2 from being lower than the voltage of the rechargeable battery 3, so that the rechargeable battery 3 may be discharged to damage the solar panel 2, in this embodiment of the application, a diode may be further disposed between the first input pin 1011 and the second input pin 1012 in the control chip 101, so as to prevent the rechargeable battery 3 from reversely discharging the solar panel 2 by using the unidirectional conduction characteristic of the diode. It should be understood that a diode may also be provided between the first input pin 1011 and the first positive interface 102, or between the first output pin 1014 and the second positive interface 104.
In the embodiment of the present application, referring to fig. 5, the control chip 101 further includes a ground pin 1016, and the ground pin 1016 is grounded and connected to the first negative interface 103. It should be noted that, in practical application, the earth can be regarded as a powerful equipotential body, and it is difficult for interference to change its potential. Therefore, after the grounding pin 1016 is connected with the first negative electrode interface 103, during the charging and discharging process, the interference current in the circuit can be output to the ground, the interference in the circuit is eliminated, and the stability is improved.
In the embodiment of the present application, referring to fig. 6, a dc blocking capacitor 108 may also be disposed on the printed circuit board 100; and the second positive interface 104 is connected to the ground pin 1016 through a dc blocking capacitor 108. By blocking the direct current and conducting the alternating current through the capacitor, the interference current (alternating current) generated in the charging process can be introduced into the grounding pin 1016, so that the interference in the charging process is reduced, and the charging efficiency is improved.
In the embodiment of the present application, referring to fig. 7, a first switch 109 may be further disposed between the first input pin 1011 and the first positive interface 102 to control conduction between the first input pin 1011 and the first positive interface 102, so that a user may manually control whether the rechargeable battery 3 needs to be charged through the solar panel 2 through the first switch 109, thereby improving controllability of the control circuit board 1.
In the embodiment of the present application, referring to fig. 8, a second switch 110 may be further disposed between the second positive electrode interface 104 and the third positive electrode interface 106 to control conduction between the second positive electrode interface 104 and the third positive electrode interface 106, so that a user may manually control whether power needs to be supplied to the light emitting element 4 through the rechargeable battery 3 by using the second switch 110 to make the light emitting element 4 emit light, thereby improving controllability of the control circuit board 1.
It should be understood that the second switch 110 may also be disposed between the third negative interface 107 and the second input pin 1012 or between the second output pin 1015 and the second negative interface 105 in the embodiment of the present application.
It should be further noted that, in the embodiment of the present invention, the first switch 109 and the second switch 110 include, but are not limited to, a touch switch, a button switch, and the like.
In the embodiment of the present application, referring to fig. 9, an adjustable resistor 111 may be further disposed between the third negative interface 107 and the second input pin 1012. Therefore, the brightness of the light emitting element 4 can be adjusted by adjusting the size of the adjustable resistor 111, so that the controllability of the control circuit board 1 is improved.
It should be understood that the adjustable resistor 111 may also be disposed between the second positive interface 104 and the third positive interface 106 in the embodiment of the present application.
In this embodiment, in order to avoid burning the control chip 101 when the positive and negative electrodes of the solar cell panel 2 are short-circuited, referring to fig. 10, a protection resistor 112 may be disposed between the first input pin 1011 and the first positive electrode interface 102, so as to concentrate a voltage on the protection resistor 112 when the positive and negative electrodes of the solar cell panel 2 are short-circuited, thereby ensuring the safety of the control chip 101.
To sum up, the embodiment of the present application provides a control circuit board 1, a control chip 101 and a control system, the control circuit board 1 is connected with a solar cell panel 2 through a first positive interface 102 and a first negative interface 103, is connected with a rechargeable battery 3 through a second positive interface 104 and a second negative interface 105, is connected with a light emitting element 4 through a third positive interface 106 and a third negative interface 107, and automatically controls the conduction of pins through the control chip 101, thereby realizing the on-off control of the solar cell panel 2, the rechargeable battery 3 and the light emitting element 4. Therefore, as the control function is integrated on the control chip, the elements required to be arranged on the whole control circuit board 1 are few, the circuit is simple, only the control chip 101 and the connecting circuits of the anode and cathode interfaces need to be designed during circuit design, and the design cost is reduced.
