[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1-7 The multifunctional wireless charger in this embodiment includes a first charging unit 1, a second charging unit 2, and a third charging unit 3. The first charging unit 1 is hinged to the top of the second charging unit 2. The second charging unit 2 has a certain depth of insertion groove 21, and a male plug 22 is fixedly installed in the insertion groove 21. The third charging unit 3 is detachably connected to the second charging unit 2 by plugging and unplugging through the insertion groove 21. The second charging unit 2 is also provided with a storage cavity 23 for storing the third charging unit.
[0034] It should be noted that the size of the inner cavity of the storage cavity 23 is adapted to the size of the third charging unit 3, so that the third charging unit 3 can be stored as a whole when it is placed inside the storage cavity 23.
[0035] It is understandable that the male connector 22 is a Type-C connector or a USB connector. When the third charging unit 3 is inserted into the connector slot 21, the male connector 22 is connected to the charging connector 31 of the third charging unit 3, so that electrical energy can be transferred from the second charging unit 2 to the third charging unit 3.
[0036] In this embodiment, a first magnetic accommodator 11 is provided on the side of the first charging unit 1 near the second charging unit 2, and the first charging unit 1 is magnetically connected to the second charging unit 2 through the first magnetic accommodator 11.
[0037] In this embodiment, the first charging unit 1 is provided with a first charging coil 12 inside, which is used to wirelessly charge the mobile phone.
[0038] In this embodiment, the second charging part 2 has a connecting cavity 24 inside, and a second charging coil 25 is provided on the inner top wall of the connecting cavity 24. The second charging coil 25 is used to wirelessly charge the earphone.
[0039] Specifically, by flipping the first charging unit 1, the top of the second charging unit 2 can be exposed. The top of the second charging unit 2 is set as the headphone charging area, so that the headphones that need to be charged can be placed in the headphone charging area and the headphones or headphone case can be wirelessly charged using the second charging coil 25.
[0040] Furthermore, a PCB board 26 is provided on the inner bottom wall of the connecting cavity 24.
[0041] In this embodiment, the first charging coil 12, the second charging coil 25, and the male connector 22 are all electrically connected to the PCB board 26.
[0042] In this embodiment, the outer side of the second charging unit 2 is provided with a plug-in female socket 27 and two sets of charging output female sockets 28 to adapt to charging plugs of different specifications.
[0043] It should be noted that the female connector 27 is a figure-8 socket, also known as a figure-8 socket; it is a common electrical connection interface, shaped like the number "8", consisting of two round or nearly round metal sockets. Its outer shell is usually made of insulating material to protect the internal conductive components and prevent short circuits. The internal structure of the figure-8 socket ensures good electrical contact and connection stability when the plug is inserted. The female connector 27 is located on the outside of the second charging section 2, together with other charging output female connectors, as the external interface part of the entire charger. The female connector 27 can be adapted to corresponding figure-8 plugs, such as some power adapters, power banks, etc. When it is necessary to charge some devices that use figure-8 plugs, the charging cable of the device can be directly inserted into the figure-8 socket, or connected through adapters or other means.
[0044] Specifically, the two sets of charging output female sockets 28 are of two specifications: Type-C and USB, to be compatible with charging cables of different charging specifications for charging.
[0045] Understandably, in addition to the regular wired charging function, when special situations arise, such as needing to connect other special devices or perform fast charging, one end of the corresponding adapter can be connected to the charging output female socket 28, and the other end can be connected to the required device. By utilizing the internal circuit conversion and control functions of the adapter, compatible charging of different devices can be achieved, meeting the charging needs of various non-standard devices and expanding the applicability of the charger.
[0046] Furthermore, the female connector 27 and the two sets of charging output female connectors 28 are electrically connected to the PCB board 26.
[0047] Specifically, the PCB board 26 is equipped with a power cord, which has a power plug for connecting to an external power source. The PCB board 26 is also equipped with a charge / discharge control module, which controls the charging power of different wireless coils.
[0048] In this embodiment, a cable reel 29 is provided inside the second charging unit 2, and a retractable charging cable 210 is wound on the cable reel 29. The cable reel 29 is electrically connected to the PCB board 26.
[0049] It should be noted that the reel 29 includes a motor and a wire roller connected to the output end of the motor. The bottom of the wire roller is rotatably connected to the inner wall of the second charging unit 2. The retractable charging cable 210 can be retracted by controlling the start and stop of the motor.
[0050] Specifically, in outdoor or mobile scenarios, the retractable charging cable 210 can be used as a portable charging cable. When you need to charge your mobile phone or other devices but it is inconvenient to use wireless charging or there is no suitable place to put it, pull out the retractable charging cable 210 to a suitable length, plug it into the device, and charge it. In addition, the automatic rewinding function of the cable reel 29 can quickly retract the retractable charging cable 210 after charging is completed, making it convenient to carry and avoiding damage to the charging cable.
[0051] In this embodiment, the outer side of the second charging unit 2 is provided with a cable outlet 211, and the telescopic charging cable 210 passes through the cable outlet 211 and extends to the outer side of the second charging unit 2.
[0052] In this embodiment, the outer side of the third charging unit 3 is provided with a charging socket 31 that is plugged and detached with the male connector 22, and the interior of the third charging unit 3 is provided with a third charging coil 32, which is used to wirelessly charge the watch.
[0053] It should be noted that after the third charging unit 3 is plugged and unplugged into the charging socket 31 via the male connector 22, it achieves electrical connection with the PCB board 26, thereby conducting electricity to the third charging coil 32 and converting it into a radio magnetic field to achieve wireless charging.
[0054] In this embodiment, the bottom of the third charging unit 3 is provided with several sets of heat dissipation holes 34 arranged in a layered annular array.
[0055] In this embodiment, the inner wall of the storage cavity 23 is provided with a second magnetic 212, and the interior of the third charging part 3 is provided with a third magnetic 33 that is magnetically connected to the second magnetic 212. The third charging part 3 is magnetically fixed by the second magnetic 212 and the third magnetic 33.
[0056] It should be noted that the first magnetic 11, the second magnetic 212, and the third magnetic 33 are all magnets, and the parts that are opposite to the positions of the first magnetic 11, the second magnetic 212, and the third magnetic 33 are iron sheets or other materials that can be attracted by magnets.
[0057] In this embodiment, the side wall of the storage cavity 23 is provided with a snap opening 231 for convenient access to the third charging unit 3.
[0058] The working principle of the above embodiments is as follows:
[0059] (1) When using the first charging unit 1, flip the first charging unit 1 to make it flat and use the first magnetic 11 to attach and fix it on the second charging unit 2 to form a charging plane for the mobile phone to be placed and charged. When it is necessary to wirelessly charge the mobile phone or other devices, place the mobile phone on the surface of the first charging unit 1. After the first charging coil 12 is energized, it generates an alternating magnetic field. The wireless charging receiving coil in the mobile phone senses the magnetic field and generates an induced current inside the mobile phone according to the principle of electromagnetic induction, thereby realizing the transmission of electrical energy and charging the mobile phone.
[0060] (2) Before using the second charging unit 2, the first charging unit 1 is flipped along the hinge to make the first charging unit 1 vertical so as to expose the headphone charging area. Then, the headphone and other devices are placed in the headphone charging area on the top of the second charging unit 2. The second charging coil 25 is electrically connected to the PCB board 26. After being powered on, an alternating magnetic field is generated. The wireless charging receiving coil in the headphone senses the magnetic field and generates an induced current, thereby realizing wireless charging of the headphone.
[0061] (3) The outer side of the second charging unit 2 is provided with a plug-in female socket 27 and two sets of charging output female sockets 28, which are electrically connected to the PCB board 26. When in use, one end of the charging cable that matches the device is inserted into the appropriate charging output female socket 28, such as a type-c or USB standard output female socket, and the other end is connected to the device that needs to be charged. The electrical energy is transmitted to the device through the charging output female socket 28 and the charging cable to realize the wired charging function and meet the charging needs of different devices.
[0062] (5) The second charging unit 2 is equipped with a retractable cable reel 29. When charging with the retractable charging cable 210, the retractable charging cable 210 at the cable outlet 211 is stretched to the required length, and the charging cable plug is connected to the device. The electrical energy is transmitted to the device through the retractable cable reel 29 and the retractable charging cable 210. When not in use, the retractable charging cable 210 is automatically retracted into the retractable cable reel 29 by the motor inside the retractable cable reel 29 to avoid the charging cable from getting tangled and to facilitate storage and next use.
[0063] (6) The third charging unit 3 is connected to the second charging unit 2 via the charging female connector 31 and the male connector 22, so as to realize the electrical connection with the PCB board 26. The third charging coil 32 is energized to generate an alternating magnetic field. When the watch or other device is placed on the surface of the third charging unit 3, the wireless charging receiving coil in the device senses the magnetic field and generates an induced current, thus completing the power transmission and realizing charging. The heat dissipation hole 34 can dissipate the heat generated during the charging process in time, ensuring the stability and safety of charging.
[0064] When the third charging unit 3 is not in use, it can be pulled out of the connector slot 21 and fixed in the storage cavity 23 by the magnetic attraction of the second magnetic body 212 and the third magnetic body 33. When needed, the third charging unit 3 can be easily removed from the storage cavity 23 using the latch 231. This storage method makes the entire charger structure more compact and easy to carry and store.
