All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes the technical scheme disclosed in the embodiments of the present application in detail with reference to the accompanying drawings.
Referring to fig. 1 to 5, an embodiment of the present application discloses a wireless charging device, which is used for wirelessly charging a device to be charged. The wireless charging device disclosed in the embodiment of the present application may be of various types, such as a wireless charger, a wireless charging post, etc., and the embodiment is not limited thereto.
The wireless charging device disclosed in the embodiment of the 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 a 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 a mounting support foundation. The device body 100 has a first charging coil assembly, and it should be understood that the device to be charged has a second charging coil assembly therein, 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 an electromagnetic induction mode, specifically, an alternating current with a certain frequency is input into a coil at a transmitting end, and a certain current is formed in a coil at a receiving end through electromagnetic induction, so that electric energy is transferred from the transmitting end to the receiving end; the first charging coil assembly may be a transmitting coil, and the second charging coil assembly may be a receiving coil.
During operation, the first charging coil assembly is required 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 power supply module supplies power to the first charging coil assembly. The specific type of the power supply module is not limited in this embodiment, and in general, the power supply module is a chargeable and dischargeable battery module, which may also be an external power source.
At present, the related wireless charging device only has one charging coil, and there is no doubt a problem of overheating during a long-time wireless charging process, based on this, the first charging coil assembly of the embodiment includes a first charging sub-coil 410 and a second charging sub-coil 420 that are distributed at intervals, and when the wireless charging device of the embodiment performs wireless charging on a device to be charged, in other words, one of the first charging sub-coil 410 and the second charging sub-coil 420 is in a working state, and the other is in a standby state, so as to avoid the problems of low charging efficiency and easy damage of the device caused by overheating of the charging coils.
The carrier 200 of the present embodiment is used for placing equipment to be charged, and can play a role in supporting the equipment to be charged; taking wireless charging as an example, the carrier 200 may be configured as a box-shaped structure, and devices such as a smart phone may be placed in the box of the carrier 200, so as 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 achieve wireless charging, the carrier 200 of the present embodiment is movably connected with the device body 100, and the carrier 200 is movable between a first position and a second position; in the first position, the carrier 200 and the first charging sub-coil 410 are distributed relatively, and the device body 100 wirelessly charges the equipment to be charged through the first charging sub-coil 410; in the second position, the carrier 200 and the second charging sub-coil 420 are distributed relatively, and the device body 100 wirelessly charges the to-be-charged equipment through the second charging sub-coil 420.
It should be appreciated that since the carrier 200 is movable between the first position and the second position, i.e., the device to be charged is movable with the carrier 200 between the first position and the second position, the device to be charged may be selectively wirelessly charged by the first charging sub-coil 410 or the second charging sub-coil 420. When the carrier 200 is located at the first position, the to-be-charged device is distributed opposite to the first charging sub-coil 410, that is, the second charging coil assembly is distributed opposite to the first charging sub-coil 410, so that the second charging coil assembly can be coupled with the first charging sub-coil 410 for wireless charging; when the carrier 200 is located at the second position, the to-be-charged device is distributed opposite to the second charging sub-coil 420, that is, the second charging coil assembly is distributed opposite to the second charging sub-coil 420, so that the second charging coil assembly can be coupled with the second charging sub-coil 420 for wireless charging.
To facilitate the position switching of the carrier 200, the driving mechanism 300 of the present embodiment is connected to the carrier 200 and drives the carrier 200 between the first position and the second position.
The temperature detection module of the present embodiment is configured to detect the temperature of the first charging coil assembly, that is, the temperature detection module is capable of detecting the temperatures 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 to be powered during operation, in this embodiment, the power supply module is further electrically connected to the driving mechanism 300 and the temperature detection module, respectively, so as to supply power to the driving mechanism 300 and the temperature detection module.
The specific types of the driving mechanism 300 and the temperature detection module are not limited in this embodiment, the driving mechanism 300 needs to be selected according to the movement requirement of the carrier 200, and the temperature detection module can be selected as a temperature detection sensor of various types.
Meanwhile, when the carrier 200 is located at 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 located at the second position and 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 overheating problem of the first charging sub-coil 410 and the second charging sub-coil 420 in the present embodiment, the wireless charging device of the present embodiment may perform temperature detection on the first charging sub-coil 410 and the second charging sub-coil 420 through the temperature detection module. When the carrier 200 is located at the first position, the second charging coil assemblies of the to-be-charged device and the first charging sub-coil 410 are distributed relatively, and the device body 100 can wirelessly charge the to-be-charged device through the first charging sub-coil 410; in the process of wireless charging through the first charging sub-coil 410, the temperature of the first charging sub-coil 410 is continuously increased, and when the critical value of the first preset temperature is reached, that is, the temperature is greater than or equal to the first preset temperature, in order to avoid overheating caused by the continuous increase of the temperature of the first charging sub-coil 410, the driving mechanism 300 drives the carrier 200 to move to the second position, at this time, the second charging coil component is no longer coupled with the first charging sub-coil 410, and the first charging sub-coil 410 can gradually decrease in temperature under the condition of no operation.
When the carrier 200 is located at the second position, the second charging coil assemblies of the to-be-charged device and the first charging sub-coil 410 are distributed relatively, and the device body 100 can wirelessly charge the to-be-charged device through the first charging sub-coil 410; in the process of wireless charging through the second charging sub-coil 420, the temperature of the second charging sub-coil 420 will continuously increase, and when the critical value of the second preset temperature is reached, that is, the temperature is greater than or equal to the second preset temperature, in order to avoid overheating caused by the continuous increase of the temperature of the second charging sub-coil 420, the driving mechanism 300 drives the carrier 200 to move to the first position again, at this time, the second charging coil component is no longer coupled with the second charging sub-coil 420, and the second charging sub-coil 420 can gradually decrease in temperature under the condition of no operation.
In this way, the first charging sub-coil 410 and the second charging sub-coil 420 keep one charging coil in the working state and the other charging coil in the waiting state all the time in the alternative use, so that after the two charging coils are alternated, the charging coil in the working state can be subjected to cooling treatment for a period of time, and the charging coil in the waiting state can be coupled with the second charging coil assembly in a lower temperature state to perform wireless charging. In summary, the wireless charging device of the embodiment can realize continuous wireless charging of the device to be charged, and can avoid overheat of the charging coil, so that higher wireless charging efficiency is ensured, and the device to be charged is not damaged.
It should be noted that, the specific values of the first preset temperature and the second preset temperature are not limited in this embodiment, and they need to be determined according to the specific working condition of the wireless charging device and the specific material of the first charging coil assembly, and only need 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 does not overheat before reaching the second preset temperature.
Further, the wireless charging device of the embodiment may further include a heat dissipation mechanism, and an output end of the heat dissipation mechanism faces the first charging coil assembly and is electrically connected with the control module. It should be understood that, when the wireless charging device performs wireless charging on the device to be charged, the heat dissipation mechanism may perform heat dissipation treatment on the first charging coil assembly, and in particular may perform heat dissipation treatment on the first charging sub-coil 410, the second charging sub-coil 420, and other charging coils, so that the rapid temperature rise of the charging coil in the working state can be avoided, and the cooling speed of the charging coil in the waiting state can also be accelerated; the control module can control the switch of the heat dissipation mechanism. In general, the heat dissipation mechanism may be selected from an axial fan, a piezoelectric spring sheet capable of driving an air flow, a suction device, and the like, and the present embodiment is not limited to a specific type of heat dissipation mechanism.
As can be seen from the above description, in the wireless charging device disclosed in the embodiments of the present application, the carrier 200 for placing the device to be charged is movably connected with the device body 100, and the driving mechanism 300 can drive the carrier 200 to move between the first position and the second position, and meanwhile, the temperature detection module can detect the temperature of the first charging coil assembly. Specifically, when the carrier 200 is located at the first position, the device body 100 may perform wireless charging on the equipment to be charged through the first charging sub-coil 410, the temperature detection module may detect the temperature of the first charging sub-coil 410, and when the temperature of the first charging sub-coil 410 rises to be greater than or equal to a first preset temperature, the driving mechanism 300 drives the carrier 200 to move to the second position, and at this time, the device body 100 may perform wireless charging on the equipment to be charged through the second charging sub-coil 420, and the first charging sub-coil 410 gradually decreases in temperature due to no operation; 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 position, at this time, the device body 100 can wirelessly charge the equipment to be charged through the cooled first charging sub-coil 410, and the second charging sub-coil 420 is gradually cooled due to no operation.
Compared with the prior art, the wireless charging device disclosed by the embodiment of the application carries out wireless charging on equipment to be charged by alternately using two independent charging coils, so that the problem of overheating caused by using only one charging coil for a long time can be avoided, and meanwhile, one of the two charging coils is always in a cooling state, so that after replacement, the device body 100 carries out wireless charging on the equipment to be charged by the charging coil kept at a lower temperature, and further, the wireless charging efficiency can be effectively improved.
Generally, the wireless charging device of the present embodiment further includes a control module, and the background system of the wireless charging device can switch 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, the power supply module supplies power to the control module, the temperature detection module can transmit detected temperature information of the first charging sub-coil 410 and the second charging sub-coil 420 to the control module, the control module is used for controlling the driving mechanism 300 to drive the carrier 200 to move between the first position and the second position according to the temperature information of at least one of the first charging sub-coil 410 and the second charging sub-coil 420, that is, the control module can prevent the temperature of the first charging sub-coil 410 from reaching a first preset temperature and prevent the temperature of the second charging sub-coil 420 from reaching a second preset temperature, and 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 alternate use of the first charging sub-coil 410 and the second charging sub-coil 420 is realized.
