More specifically, a plurality of indicator lights 18 are disposed in the base 10B and controlled by the microcontroller 13. As can be seen from fig. 3, 4 and 5, each of the indicator lights 18 has a light emitting surface exposed outside the upper cover 10C of the wireless charging stand 10. On the other hand, the temperature sensor 19 is disposed in the base 10B and electrically connected to the microcontroller 13. According to the design of the present invention, the first driving unit 16 is disposed in the base 10B and coupled between the microcontroller 13 and the at least one heat dissipation fan 17. Moreover, the second driving unit 1L is disposed in the base 10B and coupled between the microcontroller 13 and the at least one indicator light 18.
According to the design of the present invention, the microcontroller 13 has a memory unit 131 storing a plurality of setting parameters, and the plurality of setting parameters include: the system comprises a fan starting temperature, a fan stopping temperature, a first critical power, a second critical power, a third critical power, a non-charging time, a high-power charging time, a normal-power charging time, a low-power charging time and a light situation. Before starting to perform a wireless charging operation on a mobile electronic device 2M using the wireless charging device 1 of the present invention, as shown in fig. 6, a user can operate an electronic device 2E to write the setting parameters into the memory unit 131 of the microcontroller 13 through the cable 2. Of course, in the case that the cable 2 is coupled between the wireless charging device 1 and the mobile electronic device 2M, the user can operate the mobile electronic device 2M to write the aforementioned setting parameters into the memory unit 131 of the microcontroller 13 through the cable 2. It should be noted that, in the case of Near Field Communication (NFC), the user can operate the mobile electronic device 2M to write the setting parameters into the memory unit 131 of the microcontroller 13 through NFC wireless signals.
After the setting parameters are written into the memory unit 131 of the microcontroller 13, the wireless charging device 1 of the present invention can be used to perform a wireless charging operation on a mobile electronic device 2M. During the wireless charging operation, the microcontroller 13 correspondingly adjusts a transmitting power generated by the power unit 14 according to the high power charging time, the normal power charging time and the low power charging time, so that the transmitting coil unit 15 transmits a wireless charging signal with a designated power to a receiving coil unit of the mobile electronic device 2M. For example, if the specified powers are ranked low to high as 5W, 7.5W, 10W, 15W, 27W, 30W, and 40W, 30W, and 27W may be classified as high power, 15W and 10W may be classified as normal power, and 7.5W, 5W, and 5W or less may be classified as low power. It should be understood that during the high power charging time (e.g. 15 minutes), the transmitting coil unit 15 transmits wireless charging signals with 40W, 30W or 27W to the receiving coil unit of the mobile electronic device 2M. And, during the regular power charging time (e.g. 10 minutes), the transmitting coil unit 15 transmits a wireless charging signal with 15W or 10W to the receiving coil unit of the mobile electronic device 2M. Further, the transmitting coil unit 15 transmits a wireless charging signal with 7.5W, 5W or less to the receiving coil unit of the mobile electronic device 2M during the low power charging time (e.g. 5 minutes).
It should be known in the high power charging time, the utility model discloses a wireless charging device 1 uses Quick charge (Quick charge) technique to carry out Quick charge to this mobile electronic device 2M, the utility model discloses a wireless charging device 1 and/or mobile electronic device 2M tend to produce heat and pile up at Quick charge's in-process. Therefore, when an operating temperature sensed by the temperature sensor 19 is higher than or equal to the fan starting temperature, the microcontroller 13 transmits a first control signal to the first driving unit 16, so that the first driving unit 16 drives the at least one heat dissipation fan 17 to start to operate under the control of the first control signal, and a rotation speed of the heat dissipation fan 17 is increased along with the increase of the operating temperature.
As described above, after the electric quantity of the battery of the mobile electronic device 2M is charged to a predetermined value (for example, 80%) within the high power charging time by using the fast charging technology, the microcontroller 13 adjusts the transmitting power generated by the power unit 14, so that the transmitting coil unit 15 transmits a wireless charging signal with normal power or low power to the receiving coil unit of the mobile electronic device 2M. It is conceivable that the operating temperature must drop gradually during the normal (or low) power charging time. In this case, the microcontroller 13 stops the operation of the at least one radiator fan 17 when the temperature sensor 19 senses that the operating temperature is lower than or equal to the fan deactivation temperature.
The above description describes that the at least one cooling fan 17 can be controlled to be activated, to be rotated at an increased speed, to be rotated at a decreased speed, or to be deactivated according to the operating temperature. However, in a practical embodiment, the at least one cooling fan 17 may be controlled to be activated, to be rotated up, to be rotated down, or to be deactivated according to the current charging mode (i.e., according to the value of the designated power). For example, when the specified power is higher than the first threshold power, the wireless charging device 1 operates in a high-power charging mode, the first driving unit 16 starts the operation of the at least one cooling fan 17 under the control of the first control signal, and the value of the rotation speed of the cooling fan 17 changes correspondingly with the value of the specified power. When the specified power is lower than or equal to the second threshold power, the wireless charging device 1 operates in a normal power charging mode, and the first driving unit 16 decreases the rotation speed of the heat dissipation fan 17 under the control of the first control signal, and the value of the rotation speed changes correspondingly with the value of the specified power. Further, when the specified power is lower than or equal to the third threshold power, the wireless charging device 1 operates in a low power charging mode, and the first driving unit 16 stops the operation of the heat dissipation fan 17 under the control of the first control signal.
As shown in fig. 5, 7 and 8, according to the design of the present invention, the microcontroller 13 sends a second control signal to the at least one indicator light 18 to correspondingly emit a designated light effect according to the light situation in the high power charging time, the normal power charging time and the normal power charging time. For example, during the high power charging time, the specified lighting effect is a light stream with a rainbow color (rainbow) moving at a high speed. And, at the regular power charging time, the specified light effect is a light stream with a rain color moving at a regular speed. Further, at the low power charging time, the specified light effect is a rainbow streamer (light stream with rain color) moving at a low speed. Further, when the battery of the mobile electronic device 2M is charged to 100%, the designated lighting effect is a static rainbow light (rainbow color light).
In addition to the ambient light effects of high power charging, normal power charging, and low power charging, the microcontroller 13 may cause the plurality of indicator lights 18 to emit ambient light effects indicative of power-on, standby, and charging error conditions depending on the light ambient. Of course, in practical applications of the present invention, as long as more different light situations are written into the memory unit 131 of the controller 13, the plurality of indicator lights 18 can emit the light effects of the situations to represent other different situations. In other words, by changing the setting parameter of the light situation, the special situation light effect corresponding to various different situations can be changed at any time.
Furthermore, as shown in fig. 6, the user can make his electronic device 2E see through the cable 2 provides dc power to the wireless charging device 1 of the present invention, so that the wireless charging device 1 of the present invention performs a wireless charging operation on a mobile electronic device 2M. In this case, the electronic device 2E can be coupled to the microcontroller 13 through the cable 2, so as to receive a plurality of monitoring parameters of the wireless charging device 1. In other words, the Operating System (OS) of the electronic device 2E is installed with a parameter setting and monitoring application. See through at electronic device 2E the cable conductor 2 is coupled the utility model discloses a under the condition of wireless charging device 1, the user is except that this application software of operatable accomplishes a plurality of the change of setting for the parameter can also set for about the utility model discloses a plurality of monitoring parameters of wireless charging device 1 include: operating temperature, charging power, fan speed, and run time for wireless charging operations. It should be understood that the run time of the wireless charging operation may be further subdivided into a non-charging time, a high power charging time, a conventional power charging time, and a low power charging time.
It should be noted that, as shown in fig. 5, 7 and 8, the wireless charging device 1 of the present invention further includes a charging mode selecting unit K1, a light situation selecting unit K2 and a fan switch unit K3, wherein the charging mode selecting unit K1, the light situation selecting unit K2 and the fan switch unit K3 are all disposed in the base 10B and electrically connected to the microcontroller 13. As can be seen from fig. 5 and 8, the charging mode selection unit K1, the light situation selection unit K2, and the fan switch unit K3 all have a button, and each button has a pressing surface exposed outside the wireless charging stand 1. It should be understood that the user can press the charging mode selection unit K1 to switch the wireless charging device 1 of the present invention into the high power wireless charging mode, the normal power wireless charging mode, the low power wireless charging mode, or the standby mode. Also, the user may press the light context selection unit K2 to switch the designated light effect that the plurality of indicator lights 18 are now exhibiting. On the other hand, the user can press the fan switch unit 3 to enable the microcontroller 13 to control the at least one cooling fan 17 to start, increase, decrease, or stop.
