[0025] [First embodiment]

[0026] like Figure 1 As shown, the first embodiment of the utility model provides a wireless charging device 10, for example, including a first charging module 100, a second charging module 200 and a charging connection part 300. The second charging module 200 is arranged at one end of the first charging module 100. The first charging module 100 is provided with a first induction coil 110, and the second charging module 200 is provided with a second induction coil 210, so that the first charging module 100 and the second charging module 200 can respectively perform wireless power transmission with an external device. The charging connection part 300 is arranged close to the second charging module 200, and the charging connection part 300 is, for example, provided with a first electrical connector 310 electrically connected to the first induction coil 110 and the second induction coil 210, so that the charging connection part 300 is electrically connected to the external charging device through the first electrical connector 310.

[0027] For example, the external device mentioned here is, for example, an electronic device that supports wireless charging, such as a mobile phone, an electronic watch, a wireless headset, etc. The external charging device is, for example, an external mobile power supply. The first electrical connector is electrically connected to the external charging device, for example, so that the external charging device can supply power to the wireless charging device 10 or the wireless charging device 10 can supply power to the external charging device.

[0028] The embodiment of the utility model is provided with a first charging module and a second charging module that can simultaneously power an external device, so as to realize convenient wireless power transmission with multiple different types of electronic devices, which is convenient for users' daily use; and by providing a charging connection part with a first electrical connector, it can be electrically connected to an external charging device, thereby powering the wireless charging device or the external charging device.

[0029] For further information, see Figure 1 , the wireless charging device 10 also includes, for example, a steering portion 400, the steering portion 400 is connected to the first charging module 100, the second charging module 200 is arranged on one end of the steering portion 400 away from the first charging module 100, and the second charging module 200 can be turned relative to the first charging module 100 through the steering portion 400. For example, the above-mentioned steering includes, for example, displacement relationships such as bending and rotation. For example, the steering portion 400 is, for example, a flexible component, which can be made of non-metallic materials, such as leather, soft rubber and other flexible materials, or can be made of metal materials, such as memory metal components made of nickel-titanium alloy materials, and this application does not impose specific restrictions on this. Alternatively, the steering portion 400 can also be, for example, a rotating shaft. By setting the steering portion 400, the second charging module 200 and the first charging module 100 can be turned, so that it can be applied to a variety of application scenarios.

[0030] For further information, see Figure 1 , the charging connection part 300 and the turning part 400 are, for example, located at opposite ends of the second charging module 200. For example, the first charging module 100, the turning part 400, the second charging module 200, and the charging connection part 300 are, for example, located in the same direction. The charging connection part 300 can be bent relative to the second charging module 200. Through the above arrangement, the charging connection part 300 can be attached to the bottom of the external charging device, so that the first charging module 100, the turning part 400, and the second charging module 200 are all located on one side of the external charging device, so as to facilitate the user to store and carry.

[0031] Among them, the first electrical connector 310 is, for example, a metal contact connector, a Type-C connector or a Lightning connector; and / or, the wireless charging device 10 also includes a second electrical connector 500, the second electrical connector 500 is arranged on the first charging module 100 or the second charging module 200, and the second electrical connector 500 is preferably a Type-C connector or a Lightning connector. Of course, the second electrical connector 500 can also be a metal contact connector, and this application does not limit this. The wireless charging device 10 can be electrically connected to an external charging device through a Type-C connector or a Lightning connector, so that when the external charging device is a charging device without metal contacts, it can transmit power to the external charging device through a matching electrical connector or a data cable.

[0032] In addition, see Figure 1 and Figure 2 , the second induction coil 210 and the first induction coil 110 are, for example, located on the same side of the wireless charging device 10, so as to facilitate daily use by users. The first electrical connector and the second induction coil 210 are located on opposite sides of the wireless charging device. In this way, when the charging connection portion 300 is attached to the bottom of the external charging device, the first induction coil 110 and the second induction coil 210 face the side of the wireless charging device 10 away from the external charging device, so as to facilitate user use.

[0033] For further information, see Figure 2 The charging connection part 300 is provided with a first magnetic attraction part 320, for example, the first magnetic attraction part 320 is provided close to the first electrical connector 310 and is located on the same side of the charging connection part 300 as the first electrical connector 310, and the first magnetic attraction part 320 is used to connect with the external charging device by magnetic attraction. In this way, the first magnetic attraction part 320 can be magnetically attracted to the external charging device to transmit power to the external charging device, so that the user can carry it easily.

[0034] As described above, the first induction coil 110 and the second induction coil 210 are both wireless transmitting coils, so that the first wireless charging module 100 and the second wireless charging module 200 are both used to power external devices. In this way, the first wireless charging module 100 and the second wireless charging module 200 can simultaneously power external devices.

[0035] In a specific embodiment, one of the first induction coil 110 and the second induction coil 210 is a wireless transmitting coil, and the other of the two is a wireless receiving coil. For example, the first induction coil 110 is a wireless transmitting coil, so that the first wireless charging module 100 is used to power a first external device (such as a smart watch), and the second induction coil 210 is a wireless receiving coil, so that the second wireless charging module 200 is used to power the wireless charging device through a second external device. For example, when the first external device is low on power, and the second external device, such as a mobile phone, has relatively sufficient power, the second external device can be used to power the first external device through the wireless charging device 10, and the second external device, for example, assumes the role of an external charging device here. In this way, when the first external device is low on power and fails to find a suitable external charging device, the second external device can be used to power the first external device through the wireless charging device 10, so that the wireless charging device 10 can continue to charge the first external device to achieve the battery life of the first external device.

[0036] It should be noted that the first external device and the second external device mentioned above can be any electronic device supporting wireless charging, and this application does not limit this. The positions of the first charging module 100 and the second charging module 200 can be interchangeable, and this application does not limit this.

[0037] In summary, the wireless charging device provided in the first embodiment of the utility model is provided with a first charging module and a second charging module that can simultaneously power an external device, so as to realize convenient wireless power transmission with multiple different types of electronic devices, which is convenient for users' daily use; and by providing a charging connection part with a first electrical connector, it can be electrically connected to an external charging device, thereby powering the wireless charging device or the external charging device.

[0039] The second embodiment of the utility model provides a combined charging device 20, see Figure 3 The combined charging device 20, for example, includes: the wireless charging device 10 and the power supply body 21 as mentioned above, wherein the wireless charging device 10 is electrically connected to the power supply body 21 through the charging connection part 300, and the first charging module 100 and the second charging module 200 are optionally arranged on one side of the power supply body 21.

[0040] In one specific embodiment, the combined charging device 20 includes a stand state, for example, see Figure 3When the combined charging device 20 is in the stand state, the second charging module 200 contacts the support surface, and the end of the first charging module 100 away from the second charging module 200 abuts against the power supply body 21, and the first charging module 100, the second charging module 200 and the power supply body 21 form a triangular support structure to support the external device on the support surface. When the combined charging device 20 is in the stand state, the power supply body 21 can charge an external device, and the first charging module 100 can charge another external device at the same time.

[0041] Among them, see Figure 3 A first positioning portion 22 is provided on a side of the power supply body 21 close to the first charging module 100, and a second positioning portion 130 is provided on an end of the first charging module 100 away from the second charging module 200. When the combined charging device 20 is in the bracket state, the first positioning portion 22 cooperates with the second positioning portion 130 to make the first charging module 100 abut against the power supply body 21.

[0042] Specifically, the first positioning portion 22 is a groove, and the second positioning portion 130 is a plug-in portion. When the combined charging device 20 is in the bracket state, the plug-in portion is snapped into the groove. In an optional manner, the first positioning portion 22 is, for example, a second magnetic attraction portion, and the second positioning portion 130 is, for example, a third magnetic attraction portion. When the combined charging device 20 is in the bracket state, the second magnetic attraction portion and the third magnetic attraction portion are magnetically attracted to each other so that the first charging module 100 is in contact with the power source body 21.

[0043] By setting the stand state for the combined charging device 20 , the combined charging device 20 can have the function of a stand during charging, thereby improving the user experience.

[0044] In another specific embodiment, the power supply body 21 is, for example, a mobile power supply with a wireless charging function, and the combined charging device 20 also includes a flat state. When the wireless combined charging device 20 is in the flat state, the first charging module 100, the second charging module 200 and the power supply body 21 are on the same horizontal plane. At this time, the first charging module 100, the second charging module 200 and the power supply body 21 can simultaneously power external devices.

[0045] It can be understood that the aforementioned embodiments are merely exemplary descriptions of the present invention. The technical solutions of the various embodiments can be arbitrarily combined and used in combination, provided that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
