Fig. 2 is a schematic sectional view taken along a-a in fig. 1. Fig. 3 is a partial schematic view of fig. 2 according to an embodiment of the present disclosure. The present embodiment provides a charging device 1, wherein the charging device 1 includes a housing 10, the housing 10 has a receiving space 11 therein, and the housing 10 has a bearing surface 12. The charging mechanism 20 is disposed in the accommodating space 11, and the charging mechanism 20 is disposed close to the bearing surface 12. Locate the radiating element 30 in the accommodating space 11, the radiating element 30 is connected the casing 10, just the radiating element 30 is close to the charging mechanism 20, the radiating element 30 has the first face 31 that is parallel to the carrying surface 12 and the second face 32 of bending connection the first face 31. And the fan 40 is arranged in the accommodating space 11, and the fan 40 is arranged corresponding to at least part of the second surface 32.

The charging device 1 provided in the present embodiment is mainly used for charging an electronic device, so that the electronic device can be used normally. The charging apparatus 1 mainly includes a housing 10, a charging mechanism 20, a heat sink 30, and a fan 40. The housing 10 is a casing of the charging device 1, and is mainly used for installing other components of the charging device 1 in the accommodating space 11. The housing 10 has a carrying surface 12, and the carrying surface 12 is used for carrying an electronic device mounted on the charging device 1, so that the charging device 1 charges the electronic device. In addition, the housing 10 may be a single-piece structure, or the housing 10 may also be a split structure, that is, the housing 10 includes a plurality of sub-housings 10, and each sub-housing 10 is matched with each other, and the specific structure will be described later in this application.

Alternatively, the electronic devices mentioned in the present application include, but are not limited to, mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Personal Computers (PCs), Personal Digital Assistants (PDAs), Portable Media Players (PMPs), navigation devices, wearable devices, smart bands, pedometers, and fixed terminals having a charging requirement such as Digital TVs, desktop computers, and the like. In the application, the electronic equipment is taken as a mobile phone for illustration.

The charging mechanism 20 provided in this embodiment is one of the main components of the charging device 1, and the electronic device can be charged by the charging mechanism 20. Alternatively, the charging mechanism 20 is a wireless charging mechanism 20. Further optionally, the charging mechanism 20 comprises a charging coil, i.e. as shown in phantom in the figure.

The charging mechanism 20 emits heat during operation, and in order to better transfer the heat, the heat sink 30 may be added to the accommodating space 11 in this embodiment. Wherein the heat sink 30 is attached to the housing 10, thereby completing the fixing of the heat sink 30. Next, the heat sink 30 may be close to the charging mechanism 20, thereby transferring heat emitted from the charging mechanism 20 to the heat sink 30. The "close" referred to in the present application may be understood as a clearance between the heat sink 30 and the charging mechanism 20, or the heat sink 30 is attached to the charging mechanism 20. In addition, the heat sink 30 has a first surface 31 and a second surface 32, the first surface 31 is parallel to the carrying surface 12, and the second surface 32 is bent and connected to the first surface 31. Alternatively, regarding the positional relationship among the carrying surface 12, the charging mechanism 20, and the heat sink 30, the charging mechanism 20 is disposed close to the carrying surface 12, and the heat sink 30 is disposed on a side of the charging mechanism 20 away from the carrying surface 12, so that the charging mechanism 20 and the heat sink 30 are stacked in a direction perpendicular to the carrying surface 12. This can better transfer the heat of the charging mechanism 20 to the heat sink 30.

In the related art, since the charging mechanism 20 continuously radiates heat during operation, the temperature of the entire charging device 1 increases, but the normal operation of the charging device 1 is affected due to an excessively high temperature. Therefore, the charging mechanism 20 with a lower charging power is usually adopted, for example, the charging power is only 10 w. However, in the present embodiment, the heat radiation performance of the charging device 1 is improved by adding the fan 40 to the housing space 11 in the housing 10. The improvement in heat dissipation performance allows the charging mechanism 20 to use a larger charging power, for example, a high power of 40w for charging, and thus can further improve the charging performance of the charging device 1.

In addition, the fan 40 is arranged corresponding to at least part of the second surface 32, so that the arrangement structure of the charging mechanism 20, the heat dissipation member 30 and the fan 40 is changed, the charging mechanism 20, the heat dissipation member 30 and the fan 40 are not arranged in a stacking manner along a direction perpendicular to the bearing surface 12, and the thickness of the whole charging device 1 is increased. Instead, the fan 40 and the heat sink 30 are arranged in the direction of the comment bearing surface 12, thereby reducing the overall thickness of the charging apparatus 1.

In summary, the charging device 1 provided in the present embodiment can improve the heat dissipation performance of the charging device 1, improve the charging performance of the charging device 1, and reduce the thickness of the entire charging device 1. Alternatively, in some embodiments, the receiving space 11 includes a first sub-receiving space 11 and a second sub-receiving space 11 that are communicated with each other, the first sub-receiving space 11 is used for receiving the heat sink 30, and the second sub-receiving space 11 is used for receiving the fan 40.

As for the fan 40 corresponding to the whole second surface 32 of the heat dissipation member 30, it can be understood that the present application does not show a specific structural diagram.

The heat dissipation substrate 33 includes a first portion 331 and a second portion 332, the fan 40 is connected to the first portion 331, and the fin portion 34 is protruded from the second portion 332, so as to ensure the installation of the fan 40 and the fin portion 34. In addition, the fan 40 and the fin portion 34 are disposed on the same side of the heat dissipation substrate 33, so that the airflow of the fan 40 can be directly blown against the fin portion 34, thereby further improving the heat dissipation performance of the charging apparatus 1. The application is not limited herein as to whether the fan 40 blows air or sucks air against the fins 341.

Secondly, the first sub-housing 101 is rotatably connected to the second sub-housing 102, i.e. the angle between the first sub-housing 101 and the second sub-housing 102 can be changed relatively. At this time, the charging device 1 has two states: a vertical state (a state shown in fig. 7) and a horizontal state (a state shown in fig. 1), the charging device 1 is operated. The horizontal state is a state in which the angle between the first sub-housing 101 and the second sub-housing 102 is 0. The vertical state is a state when the first sub-housing 101 and the second sub-housing 102 form an included angle therebetween. Optionally, the charging device 1 may further include a rotating structure, and the rotating mechanism 50 is disposed in the first sub-housing 101.

The fan 40 in the present embodiment may be disposed corresponding to the third portion 143, so that the volume of the fan 40 may be increased, and the heat dissipation performance of the charging apparatus 1 may be further improved. And at least part of the first sub-housing 101 is disposed in the accommodating groove 13 when the charging device 1 is in the horizontal state.

And the mainboard 60 can also give off a small amount of heat at the during operation to improve the heat dissipation degree of difficulty of battery charging outfit 1. In the present embodiment, the first sub-housing 101 and the second sub-housing 102 are of a split structure, and a part of the structural members are disposed in the accommodating space 11 in the first sub-housing 101. While the second sub-housing 102 has the accommodating space 18 therein, the circuit board may be disposed in the second sub-accommodating space 11 in this embodiment, so as to further reduce the thickness of the charging device 1.
