A charging device according to an embodiment of the present invention is exemplarily described with reference to fig. 1 and 2.

The charging device includes a first housing 100 and a second housing 200.

A first wireless charging unit is disposed in the first casing 100, and the first wireless charging unit is configured to wirelessly charge a first device to be charged (e.g., a mobile phone, an earphone, a watch, etc. supporting wireless charging) located on the first side surface 110 of the first casing 100 (i.e., the upper surface of the first casing 100 in fig. 1). Specifically, the first wireless charging unit includes: the antenna comprises a main board, a first transmitting coil and a first magnetic piece. The main board mainly comprises a main control chip, a driving chip, a power device (MOS), a resistor capacitor, a PCB and the like, is electrically connected with the first transmitting coil and can drive the first transmitting coil to generate an alternating magnetic field. Referring to fig. 2, in the embodiment of the present application, the main board includes a lightning protection circuit, a rectifying and filtering circuit, a power conversion circuit, an output rectifying circuit, and a wireless charging control unit. The lightning protection circuit is used for discharging to the ground when the instantaneous voltage of alternating current input is too large so as to avoid the damage of the mainboard caused by lightning stroke or surge impact. The rectification and filtering circuit is used for rectifying and filtering alternating current passing through the lightning protection circuit to convert the alternating current into direct current, the power conversion circuit is used for converting the power of the converted direct current to enable the power to meet the power requirement of the wireless charging control unit, the output rectification circuit is used for rectifying and filtering the direct current after power conversion, and the wireless charging control unit is used for driving the first emitting coil to generate an alternating magnetic field. The wireless charging control Unit may include an MCU (micro controller Unit). The first magnetic member may be a magnet, such as a magnet surrounding the first transmitting coil, for magnetically attracting the first device to be charged. When the first device to be charged is placed on the first side 110 of the first housing 100, the first magnetic member magnetically attracts a magnetic member (e.g., a magnet or a magnetic metal such as iron) in the first device to be charged, and on one hand, can restrict movement of the first device to be charged on the first side 110; on the other hand, the first receiving coil and the first transmitting coil in the first device to be charged can be aligned, and wireless charging can be better carried out. The alternating magnetic field generated by the first transmitting coil can generate induction current in the first receiving coil of the first device to be charged, so that the first device to be charged can be wirelessly charged.

The second housing 200 is rotatably connected to the first side 110 of the first housing 100 at one end, for example, by a rotating shaft, the second housing 200 is configured to be stable when a side (a lower surface of the second housing 200 in fig. 1) facing the first housing 100 is at a first predetermined angle with the first side 110, and a second wireless charging unit is disposed in the second housing 200, and the second wireless charging unit is configured to wirelessly charge a second device to be charged (for example, a mobile phone, an earphone, a watch, etc. supporting wireless charging) located in the second housing 200. The term "stable" used herein means that when the second device to be charged is placed on the side of the second housing 200 (the upper surface of the second housing 200 in fig. 1) away from the first housing 100, the angle between the side of the second housing 200 facing the first housing 100 and the first side surface 110 does not change. In this embodiment, the second casing 200 may have a flat plate shape, and a side thereof facing the first casing 100 is parallel or approximately parallel to a side thereof away from the first casing 100. In this embodiment, the second wireless charging unit includes a second transmitting coil and a second magnetic member, the second transmitting coil is electrically connected to the main board of the first wireless charging unit, and the main board of the first wireless charging unit can drive the second transmitting coil to generate the alternating magnetic field. That is, the second transmitting coil is electrically connected with the wireless charging control unit on the main board, and the wireless charging control unit can drive the second transmitting coil to generate an alternating magnetic field. The second magnetic member may be a magnet, such as a magnet surrounding the second transmitting coil, for magnetically attracting the second device to be charged. When the second device to be charged is placed on the side of the second housing 200 away from the first housing 100, the second magnetic member magnetically attracts a magnetic member (e.g., a magnet or a magnetic metal such as iron) in the second device to be charged, and on the one hand, the second device to be charged can be restricted from moving on the second housing 200; on the other hand, the second receiving coil and the second transmitting coil in the second device to be charged can be aligned, so that wireless charging can be better carried out. The alternating magnetic field generated by the second transmitting coil can generate induced current in a second receiving coil of the second device to be charged, so that the second device to be charged can be wirelessly charged. In some other embodiments, a main board is also disposed in the second housing 200, and the main board in the second housing 200 drives the second transmitting coil to generate the alternating magnetic field, and the second wireless charging unit is independent from the first wireless charging unit.

Since the second housing 200 is rotatably connected to the first housing 100 and the second housing 200 can be kept stable when the side facing the first housing 100 (the lower surface of the second housing 200 in fig. 1) is at the first predetermined angle with the first side 110, when the side facing the first housing 100 of the second housing 200 is at the first predetermined angle with the first side 110, the charging device can charge the first device to be charged by the first wireless charging unit and/or charge the second device to be charged by the second wireless charging unit. When the second housing 200 is attached to the first side surface 110, the second housing 200 covers a partial area of the first side surface 110, for example, an area where the first wireless charging unit performs wireless charging, and at this time, the charging device is in a folded state, so that the occupied space is reduced, and the carrying and transportation are convenient; of course, at this time, the charging device can also wirelessly charge the second device to be charged located on the side of the second housing 200 away from the first housing 100 through the second wireless charging unit.

When the second magnetic part is attracted to a different first magnetic part, the side of the second housing 200 facing the first housing 100 is at a different inclination angle with respect to the first side 110 of the first housing 100. Therefore, the second housing 200 can be adjusted between a plurality of angles (for example, 30 °, 45 °, 60 ° or the like) by adjusting the installation position of the first magnetic part, and the second housing 200 can be kept stable at the corresponding angle by the attraction between the first magnetic part and the second magnetic part. Therefore, when the user charges through the second shell 200, the angle between the second shell 200 and the first shell 100 can be adjusted to a suitable angle, the personalized requirement of the user is met, meanwhile, the angle can be adjusted to a suitable angle, so that the user can wirelessly charge a device such as a smart phone and watch videos, and the charging device can be used as a mobile phone support.
