Referring to FIGS. 1 to 5 , an embodiment of the present application discloses a wireless charging apparatus, and the disclosed wireless charging apparatus is used for wirelessly charging a device to be charged. The wireless charging devices disclosed in the embodiments of the present application may have various types, such as wireless chargers, wireless charging piles, and the like, which are not limited in this embodiment.

The wireless charging device disclosed in the embodiments of the present application includes a device body 100 , a carrier 200 , a driving mechanism 300 , a temperature detection module, and a power supply module.

The device body 100 is the main component of the wireless charging device, and the carrier 200 , the driving mechanism 300 , the temperature detection module, the power supply module, and the like provide the basis for installation and support. The device body 100 has a first charging coil assembly. It should be understood that the device to be charged has a second charging coil assembly, and the first charging coil assembly can be coupled with the second charging coil assembly to realize wireless charging of the device to be charged.

It should be noted that the wireless charging technology mainly adopts the electromagnetic induction mode. Specifically, an alternating current of a certain frequency is input to the coil at the transmitting end, and a certain current is formed at the coil at the receiving end through electromagnetic induction, thereby transferring the electric energy from the transmitting end to the receiving end. The aforementioned first charging coil assembly can be the transmitter coil, and the second charging coil assembly is correspondingly the receiver coil.

During operation, the first charging coil assembly needs to be powered, so that the wireless charging device can smoothly realize wireless charging. In this embodiment, the first charging coil assembly is electrically connected to the power supply module, and the first charging coil assembly is powered by the power supply module. This embodiment does not limit the specific type of the power supply module. Generally, the power supply module is a rechargeable battery module, which may also be an external power supply.

At present, there is only one charging coil in the related wireless charging device, and there will undoubtedly be a problem of overheating during the long-term wireless charging process. Based on this, the first charging coil assembly in this embodiment includes the first charging sub-coils 410 distributed at intervals. and the second charging sub-coil 420, when the wireless charging apparatus of this embodiment wirelessly charges the device to be charged, the first charging sub-coil 410 and the second charging sub-coil 420 are alternately used, in other words, the first charging sub-coil 410 and the second charging sub-coil 420 are alternately used. One of the second charging sub-coils 420 is in a working state, and the other is in a standby state, thereby avoiding the problems of low charging efficiency and easy damage to equipment caused by overheating of the charging coil.

The carrier 200 in this embodiment is used to place the device to be charged, and can play a bearing and support role for the device to be charged; taking the wireless charging as an example of a wireless charger, the carrier 200 can be configured as a box-shaped structural member, a smart phone, etc. The device can be placed in the box of the carrier 200 to achieve stable placement on the wireless charging device.

In order to enable the device to be charged on the carrier 200 to be coupled with the first charging sub-coil 410 and the second charging sub-coil 420 to realize wireless charging, the carrier 200 in this embodiment is movably connected to the device body 100 , and the carrier 200 can be connected to the device body 100 . Move between the first position and the second position; in the first position, the carrier 200 is relatively distributed with the first charging sub-coil 410, and the device body 100 wirelessly charges the device to be charged through the first charging sub-coil 410; in the first position In two positions, the carrier 200 and the second charging sub-coil 420 are relatively distributed, and the device body 100 wirelessly charges the device to be charged through the second charging sub-coil 420 .

It should be understood that since the carrier 200 can move between the first position and the second position, that is, the device to be charged can move between the first position and the second position with the carrier 200, the device to be charged can be Wireless charging is selectively performed through the first charging sub-coil 410 or the second charging sub-coil 420 . When the carrier 200 is in the first position, the device to be charged is relatively distributed with the first charging sub-coil 410, that is, the second charging coil assembly is relatively distributed with the first charging sub-coil 410, so that the second charging coil assembly can be connected with the first charging sub-coil 410. A charging sub-coil 410 is coupled to perform wireless charging; when the carrier 200 is at the second position, the device to be charged and the second charging sub-coil 420 are relatively distributed, that is, the second charging coil assembly and the second charging sub-coil 420 are relatively distributed , so that the second charging coil assembly can be coupled with the second charging sub-coil 420 to perform wireless charging.

In order to facilitate the position switching of the carrier 200, the driving mechanism 300 of this embodiment is connected to the carrier 200, and drives the carrier 200 to move between the first position and the second position.

The temperature detection module of this embodiment is used to detect the temperature of the first charging coil assembly, that is, the temperature detection module can detect the temperature of the first charging sub-coil 410 and the second charging sub-coil 420 .

Since the driving mechanism 300 and the temperature detection module also need power supply during operation, in this embodiment, the power supply module is also electrically connected to the driving mechanism 300 and the temperature detection module, respectively, so as to perform the operation on the driving mechanism 300 and the temperature detection module. powered by.

This embodiment does not limit the specific types of the driving mechanism 300 and the temperature detection module. The driving mechanism 300 needs to be selected according to the motion requirements of the carrier 200, and the temperature detection module can be selected from various types of temperature detection sensors.

At the same time, when the carrier 200 is in the first position and the temperature of the first charging sub-coil 410 is greater than or equal to the first preset temperature, the driving mechanism 300 drives the carrier 200 to move to the second position; when the carrier 200 is in the first position In the second position, when the temperature of the second charging sub-coil 420 is greater than or equal to the second preset temperature, the driving mechanism 300 drives the carrier 200 to move to the first position.

Specifically, in order to avoid the problem of overheating of the first charging sub-coil 410 and the second charging sub-coil 420 in this embodiment, the wireless charging device in this embodiment can monitor the first charging sub-coil 410 and the first charging sub-coil 410 and the second charging sub-coil 420 through a temperature detection module.

When the temperature of the charging sub-coil 410 continues to rise and overheats, the driving mechanism 300 drives the carrier 200 to move to the second position. At this time, the second charging coil assembly is no longer coupled with the first charging sub-coil 410, and the first charging sub-coil The coil 410 may gradually cool down when not in operation.

When the carrier 200 is in the second position, the second charging coil assembly of the device to be charged is relatively distributed with the first charging sub-coil 410, and the device body 100 can wirelessly charge the device to be charged through the first charging sub-coil 410; During the wireless charging process of the second charging sub-coil 420, the temperature of the second charging sub-coil 420 will continue to increase. The temperature of the secondary charging sub-coil 420 continues to rise and overheats, and the driving mechanism 300 drives the carrier 200 to move to the first position again. At this time, the second charging coil assembly is no longer coupled to the second charging sub-coil 420, and the second charging The electronic coil 420 may gradually cool down when not in operation.

In this way, the first charging sub-coil 410 and the second charging sub-coil 420 are used alternately, and one charging coil is always in a working state, and the other charging coil is in a standby state. Therefore, after the two charging coils are alternated, The charging coil in the working state can be cooled for a period of time, and the charging coil in the standby state can be coupled with the second charging coil assembly in a lower temperature state to perform wireless charging. To sum up, the wireless charging apparatus of this embodiment can continuously wirelessly charge the device to be charged, and can avoid overheating of the charging coil, which not only ensures high wireless charging efficiency, but also ensures that the device to be charged will not be damaged.

It should be noted that this embodiment does not limit the specific values of the first preset temperature and the second preset temperature, which need to be determined according to the specific working conditions of the wireless charging device and the specific material of the first charging coil assembly, and only need to be It is only necessary to ensure that the temperature of the first charging sub-coil 410 does not overheat before reaching the first preset temperature and the temperature of the second charging sub-coil 420 before reaching the second preset temperature.

Further, the wireless charging device of this embodiment may further include a heat dissipation mechanism, and the output end of the heat dissipation mechanism faces the first charging coil assembly and is electrically connected to the control module. It should be understood that, when the wireless charging device wirelessly charges the device to be charged, the heat dissipation mechanism can perform heat dissipation processing on the first charging coil assembly, specifically, the first charging sub-coil 410, the second charging sub-coil 420 and others. The charging coil conducts heat dissipation treatment, that is, it can avoid the rapid temperature rise of the charging coil in the working state, and can also speed up the cooling speed of the charging coil in the standby state; the control module can control the switch of the heat dissipation mechanism. Generally, the heat dissipation mechanism can be selected from an axial flow fan, a piezoelectric elastic sheet capable of driving airflow, a suction device, and the like, and this embodiment does not limit the specific type of the heat dissipation mechanism.

Specifically, when the carrier 200 is at the first position, the device body 100 can wirelessly charge the device to be charged through the first charging sub-coil 410 , and the temperature detection module can detect the temperature of the first charging sub-coil 410 . When the temperature of the charging sub-coil 410 rises to be greater than or equal to the first preset temperature, the driving mechanism 300 drives the carrier 200 to move to the second position. At this time, the device body 100 can wirelessly connect the device to be charged through the second charging sub-coil 420 charging, and the first charging sub-coil 410 gradually cools down due to inactivity; when the temperature of the second charging sub-coil 420 rises to be greater than or equal to the second preset temperature, the driving mechanism 300 drives the carrier 200 to move to the first At this time, the device body 100 can wirelessly charge the device to be charged through the cooled first charging sub-coil 410, and the second charging sub-coil 420 gradually cools down due to inactivity.

One of the charging coils is always in a cooling state, so after the replacement, the device body 100 wirelessly charges the device to be charged through the charging coil maintained at a lower temperature, thereby effectively improving the wireless charging efficiency.

Generally, the wireless charging device of this embodiment further includes a control module, and the background system of the wireless charging device can switch between different charging states through the control module. Specifically, the control module is electrically connected to the power supply module, the temperature detection module and the driving mechanism 300 respectively, the power supply module supplies power to the control module, and the temperature detection module can detect the first charging sub-coil 410 and the first charging sub-coil The temperature information of the second charging sub-coil 420 is transmitted to the control module, and the control module is used to control the driving mechanism 300 to drive the carrier 200 to move in the first charging sub-coil 410 and the second charging sub-coil 420 according to the temperature of at least one of the first charging sub-coil 410 and the second charging sub-coil 420 The movement between the first position and the second position means that the control module can prevent the temperature of the first charging sub-coil 410 from reaching the first preset temperature according to the temperature information of the first charging sub-coil 410 and the second charging sub-coil 420 , and To prevent the temperature of the second charging sub-coil 420 from reaching the second preset temperature, when the control module controls the driving mechanism 300 to drive the carrier 200 to move between the first position and the second position, the first charging sub-coil 410 is realized.
