Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the present invention is directed to a wireless charging device including: a power supply module 1; aligning the female module 2; an alignment detection module 3; the main control unit module 4 is connected with the power supply module 1 and the alignment detection module 3 respectively; under the condition that the device to be charged 5 is aligned with the preset point of the alignment mother module 2, the alignment detection module 3 sends an alignment signal to the main control unit module 4; the main control unit module 4 sends a charging instruction signal to the power supply module 1 according to the alignment signal, wherein the charging instruction signal is used for instructing the power supply module 1 to wirelessly charge the device to be charged 5.
It should be noted that, a plurality of preset points may be generally arranged, for example, 4 or 6. In the case where the device to be charged 5 is aligned with each of the predetermined points, the device to be charged 5 is aligned with the alignment module. Therefore, the accuracy of alignment of the two can be improved, and the efficiency of wireless charging is improved.
According to the wireless charging device provided by the utility model, under the condition that the device to be charged is aligned with the alignment female module, the main control unit module can control the power supply module to wirelessly charge the device to be charged by sending the alignment signal to the power supply module. Through the mode that adopts wireless charging, inconvenience and the puzzlement of avoiding numerous and diverse pencil when can avoid utilizing wired charger to charge have improved the use and have experienced to the user.
In the wireless charging device provided by the embodiment of the present invention, the alignment detection module 3 includes an induction coil 31, and the induction coil 31 is wound around the outer surface of the alignment female module 2; when the device to be charged 5 is aligned with the preset point of the alignment female module 2, the alignment female module 2 moves in a direction perpendicular to the induction coil 31 to generate an alignment signal.
It should be noted that the induction coil 31 may be wound with a plurality of turns around the outer surface of the alignment mother module 2. The induction coil 31 is wound for a plurality of turns to form a containing cavity which is through up and down.
It should be noted that the outer surface of the induction coil 31 does not conform to the alignment master module 2, but rather is left with a gap. Therefore, the alignment female module 2 can move in the accommodating cavity, and the alignment female module 2 can cut the magnetic induction lines of the induction coil 31 in the moving process, so that the induction coil 31 generates instant current, namely, the alignment signal is generated.
According to the wireless charging device provided by the embodiment of the utility model, the wireless charging device further comprises an electromagnet coil 6, the electromagnet coil 6 is wound on the outer surface of the alignment female module 2, the electromagnet coil 6 is not overlapped with the induction coil 31, and the electromagnet coil 6 is connected with the power supply module 1; and when the current intensity of the alignment signal is greater than or equal to the target current intensity, sending a starting signal for supplying power to the electromagnet coil 6 to the power supply module 1.
It should be noted that the electromagnet coil 6 and the induction coil 31 are not overlapped, so that the mutual influence between the two can be avoided. The manner of winding the electromagnet coil 6 to the mother module 2 may be the same as the manner of winding the induction coil 31 to the mother module 2, and will not be described herein.
In addition, an alignment signal is generated during the alignment of the device to be charged 5 with the alignment mother module 2. Different current intensities of the alignment signals represent different alignment states. The fact that the device to be charged 5 is aligned with the alignment mother module 2 is only indicated if the current intensity of the alignment signal is greater than or equal to the target current intensity. The power supply of the electromagnet coil 6 can be realized by sending a start signal for supplying power to the electromagnet coil 6 to the power supply module 1. The above-mentioned aligning female module 2 has magnetism, and the electromagnet coil 6 can increase the magnetism of the aligning female module 2 under the condition that current passes through, thereby enhancing the adsorption effect of the device to be charged 5. On the one hand, the charging device 5 can be prevented from falling in the wireless charging process, and on the other hand, the anti-theft function can be achieved.
Referring to fig. 2, in the wireless charging device provided in the embodiment of the present invention, the alignment female module 2 includes a plurality of first magnetic elements 21 having a stroke displacement; wherein, a part of the target first magnetic elements 21 in the plurality of first magnetic elements 21 are located at a predetermined point, and the alignment detection module 3 generates an alignment signal when all the part of the target first magnetic elements 21 at the predetermined point are aligned with the device to be charged 5.
The first magnetic element 21 may be a magnet having a cylindrical shape, for example, a rubidium magnet, or another type of magnet. Here, the first magnetic element 21 will be described as an example of a rubidium magnet. The magnetic property of rubidium magnet is stronger, when adsorbing with waiting that charging device 5 magnetism is inhaled, compares ordinary magnet, and its adsorption effect is better.
In this figure, one way of winding induction coil 31 and electromagnet coil 6 around the outside surface of the rubidium magnet is seen. In the process of aligning the female module 2 with the device to be charged 5, because the rubidium magnet has a stroke displacement, the rubidium magnet can cut the magnetic induction line of the induction coil 31, thereby generating an alignment signal. When the current intensity of the alignment signal is greater than or equal to the target current intensity, the power supply module 1 supplies power to the electromagnet coil 6, and the magnetism of the rubidium magnet can be enhanced by utilizing the principle of the electromagnet.
Further, for example, the alignment mother module 2 includes 8 rubidium magnets, and the 8 rubidium magnets are disposed at different positions. The preset point position may be, for example, a position where 4 rubidium magnets are located, and when all of the rubidium magnets on the preset point position are aligned with the device to be charged 5, the current intensity of the alignment signal generated by the alignment detection module 3 is greater than or equal to the target current intensity. In this case, it can be determined that the alignment process is completed between the alignment mother module 2 and the module to be charged, and the device to be charged 5 can be wirelessly charged.
Alternatively, the rubidium magnet has a stroke displacement, which can be understood as that the moving unit 211 inside the rubidium magnet has a stroke displacement. In this figure, the motion unit 211 shown by a solid line can be regarded as a state in which no displacement is generated. The motion unit 211, shown in dashed lines, can be considered as a state in which a displacement is generated. During the movement of the moving unit, the magnetic induction lines of the induction coil 31 can be cut. The arrows in the figure indicate the current flowing in the electromagnet coil 6 when the electromagnet coil 6 is powered by the power supply module 1.
The wireless charging device provided by the embodiment of the utility model further comprises: the main control unit module 4 is respectively connected with the image acquisition device and/or the fingerprint acquisition device; when receiving a signal that the image comparison is successful and/or a signal that the fingerprint comparison is successful, the main control unit module 4 sends a termination signal to the power supply module 1, wherein the termination signal stops supplying power to the electromagnet coil 6; and if the fingerprint information acquired by the fingerprint acquisition device is consistent with the target fingerprint information included in advance, the fingerprint comparison is successful.
It should be noted that the target image information and the target fingerprint information that are saved in advance may be pre-stored in the wireless charging device or may be stored in a remote server.
As mentioned above, in the case of wireless charging of the device to be charged 5, the electromagnet coil 6 enhances the magnetic properties of the rubidium magnet, and the user cannot directly remove the device to be charged 5. By stopping the power supply to the electromagnet coil 6 in the case of successful image comparison and/or successful fingerprint comparison, the effect of enhancing the magnetic properties of the rubidium magnet can be eliminated. In this way, the user can remove the device to be charged 5. If the image comparison fails and/or the fingerprint comparison fails, the user cannot take down the device to be charged 5, so that the anti-theft effect can be achieved.

The alignment submodule 7 is shown for example to comprise 8 second magnetic elements (not all second magnetic elements are shown in the figure).

When the first electromagnetic element 21 is determined to be completely absorbed, the main control unit module 4 controls the power supply module 1 to supply power to the electromagnet coil 6, so that the magnetism of the first electromagnetic element 21 is enhanced. Through the magnetism of reinforcing first electromagnetic element 21, can realize that intelligent helmet still can firmly fix on wireless charging device when on-vehicle jolting, not healthy and full the use. In addition, the main control unit module 4 starts wireless charging on the intelligent helmet only when the first magnetic elements 21 determining the preset point are completely adsorbed, so that false triggering caused by adsorption of other electronic devices or helmets of other models can be prevented.
