Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] It should be noted that the directional terms mentioned in the embodiments of this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model. For the sake of understanding and ease of description, the dimensions and thicknesses of each component shown in the drawings are arbitrarily shown, but this utility model is not limited thereto.

[0032] It is understood that when a component, such as a layer, membrane, region, or substrate, is referred to as "on" another component, the component may be directly on the other component, or there may be intermediate components present. Furthermore, in the specification, unless explicitly stated otherwise, the word "comprising" will be understood to mean including the stated component, but not excluding any other components. Additionally, in the specification, "on" means located above or below the target component, and does not mean necessarily located on top of it based on gravity.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] like Figure 1 As shown, this embodiment of the present invention provides a charging device 10. The charging device 10 provided in this embodiment of the present invention is used, for example, to charge electronic devices. Specifically, see... Figure 1 The charging device 10 includes, for example, a charging body 100, an external charging device 200, and a connecting cable 300. The charging body 100 internally houses, for example, the basic structure of a mobile power bank, such as a charging module and a circuit board. The external charging device 200 is electrically connected to the charging body 100 via the connecting cable 300. The external charging device 200 includes, for example, a wireless charging structure 210 and a charging cable 220. The wireless charging structure 210 and the charging cable 220 are respectively electrically connected to the charging module via the connecting cable 300. The wireless charging structure 210 provides wireless power to a first external device, and the charging cable 220 provides power to a second external device. For example, the charging cable mentioned above could be a data cable, the first external device could be an electronic device such as a watch or mobile phone that supports wireless charging, and the second external device could be an electronic device that can be charged via a data cable. This allows multiple electronic devices to be charged simultaneously.

[0035] The charging device provided in this embodiment avoids the charging body from becoming too bulky by setting the wireless charging structure inside an external charging device, which is electrically connected to the charging body. This improves portability. Furthermore, by combining the wireless charging structure with a charging cable, the device can meet the user's need to charge multiple devices.

[0036] For details, see Figure 2 and Figure 3The external charging device 200 includes, for example, an upper housing 201 and a lower housing 202. The external charging device 200 is provided with, for example, a charging cable storage slot 230, which is disposed on the lower housing 202. The charging cable 220 includes a terminal 221 and a connector 222 disposed opposite to each other. The terminal 221 is electrically connected to the external charging device 200, and the connector 222 is used to connect to a second external device. The charging cable storage slot 230 is used to store the connector 222. When the charging cable 220 is stored in the charging cable storage slot 230, a handle space 223 is formed between the terminal 221 and the connector 222. For example, the connector 222 can be fixed to the charging cable storage slot 230 of the external charging device 200 by means of adhesive, magnetic connection, etc. By setting up the charging cable storage slot 230, the connector end 222 can be fixed to the charging cable storage slot 230 when not in use to form a handle space, so that the user can put his hand into the handle space to lift the charging device 10, which makes it convenient for the user to carry it on a daily basis.

[0037] Preferably, see Figure 4 The external charging device 200 is provided with a first magnetic attractor 240, and the connector end 222 is provided with a second magnetic attractor 224. When the charging cable 220 is stored in the charging cable storage slot 230, the first magnetic attractor 240 and the second magnetic attractor 224 are magnetically attracted to each other. For example, the first magnetic attractor 240 and the second magnetic attractor 224 can be magnetically attracted parts, such as the first magnetic attractor 240 being a magnet and the second magnetic attractor 224 being an iron sheet, or the first magnetic attractor 240 being an iron sheet and the second magnetic attractor 224 being a magnet, or both the first magnetic attractor 240 and the second magnetic attractor 224 being magnets. This invention does not specifically limit this, as long as the first magnetic attractor 240 and the second magnetic attractor 224 can attract each other. This increases the fixing strength of the connector end 222 in the charging cable storage slot 230, thereby improving the lifting stability and reducing the possibility that the connector end 222 of the charging cable 220 may fall out of the charging cable storage slot 230 when the user lifts the handle space 223.

[0038] In one specific implementation, see Figure 2 and Figure 3 The charging cable storage slot 230 and the wireless charging structure 210 are respectively disposed on opposite sides of the external charging device 200 along the thickness direction of the external charging device. The thickness direction of the external charging device mentioned above is, for example,... Figure 3The x-direction in the middle. By designing the specific structure of the external charging device 200, the size of the external charging device 200 can be reduced, and when the external charging device 200 wirelessly charges the electronic watch, this design allows the watch strap to be conveniently placed across both sides of the external charging device 200.

[0039] For details, please refer to [link / reference]. Figure 2 and Figure 3 The wireless charging structure 210 is located between the upper housing 201 and the lower housing 202, and is disposed close to the upper housing 201. The charging cable storage slot 230 is disposed on the lower housing 202. Further, the wireless charging structure 210 includes, for example, a wireless charging coil 211, a magnetic shielding member 212, and a third magnetic suction member 213. The magnetic shielding member 212 is sleeved on the outside of the third magnetic suction member 213, and the wireless charging coil 211 is sleeved on the outside of the magnetic shielding member 212. The third magnetic suction member 213 is, for example, a magnet, used to attract a first external device so that the wireless charging structure 210 can wirelessly charge the first external device. The magnetic shielding member 212 is, for example, made of a magnetic shielding material such as ferrite, and is used to prevent the magnetic field of the third magnetic suction member 213 from interfering with the wireless charging coil 211. By designing the positions of the wireless charging coil 211, the magnetic shielding component 212, and the third magnetic suction component 213, the required installation space can be saved as much as possible, thereby reducing the overall size of the external charging device 200.

[0040] See Figure 5 The charging cable 220 has an interface portion 225 and a blocking portion 226 on its connector end 222. The interface portion 225 is located at the end of the blocking portion 226 away from the connector end 221. For example, the interface portion 225 is a charging interface. When the charging cable 220 is connected to an external device, the interface portion 225 is connected to the charging interface of the external electronic device, and the blocking portion 226 abuts against the external electronic device. Specifically, the blocking portion 226 has an inclined portion 227 at the end away from the interface portion 225. The charging cable storage groove 230 includes a first groove end 231 and a second groove end 232. The second groove end 232 is inclined and corresponds to the inclined portion 227. When the connector end 222 is stored in the charging cable storage groove 230, the inclined portion 227 and the second groove end 232 abut against each other. By setting the inclined part 227 and the second inclined part that abut against each other, an inverted structure can be formed between them, thereby reducing the possibility that the connector end 222 of the charging cable 220 will fall out of the charging cable storage slot 230 when the user lifts the handle space 223, and improving the lifting stability.

[0041] As stated above, see also Figure 5 and Figure 6When the inclined portion 227 and the second groove end 232 abut against each other, there is a gap 233 between the first groove end 231 of the charging cable storage groove 230 and the end of the blocking portion 226 away from the inclined portion 227. By providing a gap 233 between the end of the charging cable storage groove 230 away from the inclined portion and the end of the blocking portion 226 away from the inclined portion 227, it is convenient for the user to push the connector end 222 of the charging cable 200 to remove the connector end 222 from the charging cable storage groove 230. For example, if the connector end 222 of the charging cable 200 is magnetically connected to the external charging device 200, and the user needs to exert a lot of force to remove the connector end 222 of the charging cable 200 from the charging cable storage slot 230, a gap 233 is set so that the user pushes the connector end 222, causing the connector end 222 to be misaligned with the magnetic element of the external charging device 200, reducing the magnetic force, and thus making it easier for the user to remove the connector end 222 of the charging cable 200 from the charging cable storage slot 230.

[0042] Preferably, see again Figure 5 and Figure 6 In the longitudinal direction of the external charging device, the width w of the gap 233 is 0.5 mm to 3 mm. The longitudinal direction of the aforementioned external charging device is, for example,... Figure 5 In the y-direction. By designing the width w of the gap 233, on the one hand, it can avoid the gap 233 being too small, which would result in the connector end 222 of the charging cable 200 having too small a pushing distance in the charging cable storage slot 230, thus making it inconvenient to remove the connector end 222 of the charging cable 200; on the other hand, it can avoid the gap 233 being too large, which would make it easy for debris to enter the gap 233 and thus hinder the pushing of the connector end 222 in the charging cable storage slot 230.

[0043] In addition, in one specific implementation, see Figure 2 The external charging device 200 also includes a circuit board 250, and the connecting line 300, the wireless charging structure 210, and the charging cable 220 are electrically connected to the circuit board 250. Specifically, the circuit board 250 is provided with a clearance portion 251, and the first magnetic suction member 240 is located within the clearance portion 251, which further reduces the size of the external charging device 200.

[0044] As described above, the connecting cable 300 is provided with an anti-detachment portion 301; and / or, the charging cable 220 is provided with an anti-detachment portion 228 at the end connected to the external charging device 200. For example, the anti-detachment portion 301 may be provided at one end of the connecting cable 300 near the external charging device 200, or the anti-detachment portion 301 may be provided at both ends of the connecting cable 300. By providing the anti-detachment portion, the charging cable 220 and the connecting cable 300 can be prevented from detaching, thereby improving lifting stability.

[0045] Preferably, see Figure 7 The number of the charging cables 220 is at least two, and the at least two charging cables 220 are spaced apart in a third direction, such as the third direction mentioned here. Figure 7 In the z-direction, by setting at least two charging cables 220, the charging device 10 can be further configured to charge multiple devices simultaneously, improving the charging efficiency of the charging device 10 when charging multiple devices and enhancing the user experience. And / or, the charging cable 220 is flat, which reduces pressure and improves the user's comfort when lifting it.

[0046] In summary, the charging device provided in this embodiment, by setting the wireless charging structure inside an external charging device and electrically connecting the external charging device to the charging main body, avoids the charging main body from being too large, thereby improving portability; and by combining the wireless charging structure with a charging cable, it can meet the user's need to charge multiple devices.

[0047] It is understood that the foregoing embodiments are merely illustrative examples of this utility model. Provided that the technical features do not conflict, the structure is not contradictory, and the purpose of this utility model is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
