[0048] The following describes the charging device of the embodiment of the present application. However, it is easy to understand that the embodiment of the present application provides many suitable creative concepts and can be implemented in a wide variety of specific contexts. The specific embodiment shown is only used to illustrate the use of the present application in a specific way, and is not used to limit the scope of the present application.

[0049] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0050] The following disclosures in this specification are specific examples of describing various components and their arrangement methods, in order to simplify the description. Of course, these specific examples are not intended to limit the present application. For example, if the following disclosures in this specification describe forming a first feature on or above a second feature, it means that it includes an embodiment in which the first feature formed is in direct contact with the second feature, and also includes an embodiment in which an additional feature can be formed between the first feature and the second feature, so that the first feature and the second feature may not be in direct contact. Furthermore, in order to facilitate the description of the relationship between one feature and another feature in the accompanying drawings, spatially related terms such as "below", "below", "below", "above", "above", and similar terms can be used. In addition to the orientations shown in the accompanying drawings, spatially related terms cover different orientations of the device in use or operation. The device can also be positioned in another way (rotated 90 degrees or in other orientations), and the spatially related descriptions used herein can also be interpreted accordingly.

[0051] Figure 1 is a schematic diagram showing a charging device C according to an embodiment of the present application, and Figure 2 Yes means Figure 1 The charging device C can be used to supply power to one or more power storage components to store the power in the power storage components. For example, the power storage component can be a battery (e.g., including a nickel-cadmium battery, a nickel-metal hydride battery, a lithium-ion battery, a lithium-ion polymer battery, and / or a lead-acid battery), but is not limited thereto.

[0052] like Figure 1 and Figure 2 As shown, the aforementioned charging device C may mainly include a first shell 100, a second shell 200, a channel 300, one or more electronic components 400, and a fan 500. The first shell 100 may have a top wall 110, a plurality of side walls 120, and a bottom wall 130. The top wall 110 and the bottom wall 130 are located on opposite sides of the first shell 100, and the side wall 120 connects the top wall 110 and the bottom wall 130. Therefore, an internal space 101 surrounded by the top wall 110, the side wall 120 and the bottom wall 130 may be formed inside the first shell 100. At least one opening 111 is formed on the top wall 110, and at least one air hole 121 is formed on one of the side walls 120.

[0053] The second shell 200 is disposed on the top wall 110 of the first shell 100 and has a receiving space 201. When the user intends to charge the storage component using the charging device C, the storage component can be received in the receiving space 201 of the second shell 200. The shape of the inner surface of the second shell 200 facing the receiving space 201 can match the shape of the storage component to be charged, so when the user places the storage component in the receiving space 201, the storage component can be directly positioned. At least one opening 211 can be formed on the wall surface 210 of the second shell 200 in contact with the first shell 100, and the opening 211 can be aligned with the opening 111 on the top wall 110 of the first shell 100, so that a through hole P passing through the first shell 100 and the second shell 200 can be formed. In addition, at least one opening 221 can also be formed on the wall surface 220 of the second shell 200 facing away from the first shell 100, and the opening 221 can connect the receiving space 201 and the external environment. In this embodiment, the position of the through hole P may correspond to the position of the opening 221 .

[0054] The channel 300 may pass through the first housing 100. In particular, the wall surface 310 of the channel 300 may separate the channel 300 from the internal space 101 of the first housing 100. In other words, the channel 300 will not communicate with the internal space 101 of the first housing 100. The channel 300 may completely cover the opening 111 on the top wall 110 and the air hole 121 on the side wall 120, so that the through hole P formed by the opening 111 and the opening 211 may communicate the channel 300 with the accommodation space 201, and the air hole 121 may communicate the channel 300 with the external environment.

[0055] The electronic component 400 may be accommodated in the inner space 101 of the first housing 100 and may contact the wall surface 310 of the channel 300. The shape of the wall surface 310 of the channel 300 may match the shape of the electronic component 400. For example, Figure 2 As shown, the wall 310 of the channel 300 may have a first section 311 and a second section 312, the first section 311 is separated from the electronic component 400 by a distance, and the second section 312 contacts the electronic component 400. Since the shape of the wall 310 of the channel 300 matches the shape of the electronic component 400, an obtuse angle θ may be formed between the first section 311 and the second section 312. In this embodiment, the second section 312 may be substantially perpendicular to the side wall 120 of the first housing 100 having the air hole 121. The aforementioned electronic component 400 may include, for example, a power supply, a processor, a circuit board, a resistor, a capacitor, a wire, and / or a wireless charging coil, etc., but is not limited thereto.

[0056] The fan 500 is disposed in the passage 300 and adjacent to the through hole P. In this embodiment, the distribution range R1 of the air holes 121 on the side wall 120 is larger than the projection range R2 of the fan 500 on the top wall 110 of the first housing 100. The fan 500 can drive air flow so that air in the external environment flows through the passage 300 and the accommodating space 201.

[0057] The following describes how to use the charging device C. Figure 3 As shown, when the power storage component B is placed in the accommodation space 201 of the second shell 200, the charging device C can supply power to the aforementioned power storage component B (for example, supplied by the electronic component 400), and the power storage component B and the electronic component 400 will generate heat energy. At this time, the fan 500 can start to operate, driving the air in the external environment to enter the accommodation space 201 through the opening 221 of the second shell 200. After the aforementioned accommodation space 201 flows through the accommodation space 201, the perforation P and the channel 300 in sequence, it can leave the charging device C through the air hole 121 on the first shell 100.

[0058] Since the air flows through the storage space 201 containing the storage component B, the heat energy generated by the storage component B can be taken away. At the same time, since the electronic component 400 is in contact with the wall surface 310 of the channel 300, the air can also take away the heat energy of the electronic component 400 after the heat energy generated by the electronic component 400 is transferred to the wall surface 310 of the channel 300. Since the charging device C of the present application can significantly reduce the temperature of the storage component B and the electronic component 400, the charging efficiency of the charging device C can be effectively improved, and the malfunction of the charging device C due to overheating can be avoided.

[0059] Since the second section 312 forms an obtuse angle θ with the first section 311 , the air can completely flow through the second section 312 contacting the electronic component 400 , thereby ensuring that the air takes away the heat energy on the second section 312 .

[0060] In addition, since the wall 310 of the channel 300 can separate the channel 300 and the internal space 101 of the first shell 100, the charging device C of the present application can keep the internal space 101 closed while lowering the temperature of the electronic component 400 through air flow, thereby preventing foreign matter or liquid from entering the internal space 101 and ensuring the waterproofness of the charging device C.

[0061] When the external environment temperature is low (e.g., the temperature is below zero degrees Celsius), the charging device C may further include a heater (not shown) disposed in the channel 300 or near the air hole 121. The fan 500 can be operated in reverse, and the air heated by the heater can flow through the channel 300 and the accommodation space 201 in sequence, so that the electronic component 400 and the power storage component B can be maintained at a fixed temperature and will not fail to operate due to too low a temperature.

[0062] In some embodiments, when the temperature rise of the storage component B during charging is relatively low, the fan 500 can also drive the air in the external environment to flow through the air hole 121, the channel 300, the perforation P and the accommodating space 201 in sequence, and leave the charging device C through the opening 221 of the second shell 200 to reduce the temperature of the storage component B and the electronic component 400.

[0063] See also Figure 4 , the charging device C of another embodiment of the present application may mainly include a first shell 100, a second shell 200, a channel 300, one or more electronic components 400, and a fan 500, wherein the configuration and structure of the first shell 100, the channel 300, the electronic component 400 and the fan 500 are similar to Figure 1 The charging device C shown is the same and will not be described again here.

[0064] In this embodiment, the second housing 200 has only an opening 211 formed on the wall surface 210 and aligned with the opening 111 of the first housing 100. Therefore, the second housing 200 can isolate the accommodation space 201 from the external environment, making it difficult for foreign matter or liquid to enter the accommodation space 201, thereby reducing the probability of damage to the storage component B.

[0065] In this embodiment, the fan 500 drives the air in the external environment to flow into the channel 300 through the air hole 121 , and then flows through the channel 300 and the through hole P in sequence and enters the accommodating space 201 .

[0066] In the above-mentioned embodiment, the channel 300 is formed by the wall surface 310 and the first shell 100, but it is not limited thereto. Figure 5 As shown, the channel 300 may be formed by a wall 310 surrounding the channel 300 .

[0067] See also Figure 6 In some embodiments, the charging device C may further include a heat-conducting component 600. The heat-conducting component 600 may be disposed between the wall 310 and the electronic component 400 and contact the two to transfer the heat energy of the electronic component 400 to the wall 310 transmitted to the channel 300. In this way, the charging device C will be able to dissipate heat more efficiently. In this embodiment, the heat-conducting component 600 may be disposed between the first section 311 and the electronic component 400 and contact the two. In some embodiments, the heat-conducting component 600 may also be filled between the second section 312 of the wall 310 and the electronic component 400 and contact the two. The aforementioned heat-conducting component 600 may be, for example, a thermal paste or a thermally conductive glue, but is not limited thereto.
