[0002] A power bank, also known as a power bank, is a portable battery device designed to provide temporary power to other electronic devices. With the popularity of mobile devices such as smartphones, tablets, and wearable devices, power banks have become an important accessory in daily life, especially when traveling, engaging in outdoor activities, or when there is no access to a fixed power source for a long time. It can be found that most power banks are currently designed to charge mobile phones, and on this basis, they can also charge other electronic devices. Therefore, most power banks are designed to be the size of a mobile phone. For smart watches with wireless charging functions, these power banks suitable for charging mobile phones have room for optimization in size and room for improvement in portability. In addition, when charging a watch, the strap is often difficult to place, which makes it look messy and inconvenient to carry.

[0027] The utility model provides a mobile power source.

[0028] Reference Figure 1In one embodiment of the utility model, the mobile power supply is applied to a watch with a wireless charging function; the mobile power supply includes a housing 1, a circuit board 2 and a battery 3 are arranged in the housing 1; a charging position 10 for wirelessly charging the watch is arranged on the outer surface of the housing 1, wherein the width of the charging position 10 is greater than or equal to the width of the housing 1; a wireless charging component 5 is arranged inside the housing 1 corresponding to the charging position 10, and the wireless charging component 5 includes an induction coil 11; when charging, the induction area of ​​the watch corresponds to the induction coil 11, and the watch strap is set on the outer surface of the housing 1. It can be understood that the larger the electronic device is, the larger the wireless charging induction area it has, and the larger the wireless charging induction area of ​​the charging device matched with it. For example, in general, the wireless charging induction area of ​​the charging device for smart phones is larger than the wireless charging induction area of ​​the charging device for smart watches. For the mobile power supply, the larger the wireless charging induction area, the larger the volume of the mobile power supply should be, which is contrary to the original intention of the portability of the mobile power supply. Therefore, it is necessary to redesign the smart watch with wireless charging function, rather than simply superimposing this function on the device suitable for mobile phone charging. The technical solution of the utility model reduces the volume of the mobile power supply as much as possible, reduces the weight, and thus improves portability by setting the width of the charging position 10 to be greater than or equal to the width of the housing 1, that is, making the width of the housing 1 less than or equal to the width of the charging position 10. Since the mobile power supply is small in size, when charging, the watch strap can be just set on the outer surface of the housing 1, so that the watch strap can be placed, not messy, and not easily mixed with other sundries; the watch strap is set on the outer surface of the housing 1, so that the watch and the mobile power supply are combined together, which is easier to carry, further improving portability.

[0029] In this embodiment, if Figure 1 The mobile power supply also includes a connecting line 4, a first end 41 of the connecting line 4 is connected to the battery 3, and a second end 42 of the connecting line 4 is used to connect to the electronic device. The connecting line 4 is mainly used for wired charging. Since the charging efficiency of wireless charging is lower than that of wired charging, when an emergency is needed, the wired charging method can be selected first to charge the watch. In addition, when the watch is wirelessly charged, the connecting line 4 can also be used to charge other devices at the same time to improve the charging efficiency of the mobile power supply.

[0030] Further, see Figure 2 and Figure 3The circuit board 2 is provided with a first connection port 21, and the housing 1 is provided with a first through hole 13 corresponding to the first connection port 21. The first connection port 21 is used to accommodate the second end 42 of the connecting line 4; or, the first connection port 21 is used to connect the input power supply. It can be understood that the second end 42 of the connecting line 4 can be inserted into the first connection port 21 when not in use to form a lanyard. The user can carry or move the mobile power supply by the lanyard, which further improves the portability. The first connection port 21 can also serve as an input port for the input power supply, and is used to connect the input power supply to charge the battery 3. Specifically, a fixing member 15 is provided in the first through hole 13, and when the second end 42 is located at the first connection port 21, the fixing member 15 is located between the side wall of the second end 42 and the side wall of the first through hole 13. The number of the fixing member 15 is not limited here, and it can be a single fixing member 15 located on a side wall of the first through hole 13, or multiple fixing members 15 evenly distributed on multiple side walls or a side wall; the specific form of the fixing member 15 is also not limited here, and it can be an elastic member such as a cushion, or a protruding structure. The function of the fixing member 15 is to form a supporting force on the side wall of the first through hole 13 when the second end 42 is inserted into the first connecting port 21, thereby improving the stability of the hanging rope and preventing the hanging rope from falling off during use.

[0031] In some embodiments, the circuit board 2 is provided with a second connection port 22, the housing 1 is provided with a second through hole 14 corresponding to the second connection hole, and the second connection port 22 is used to connect the input power supply. When the first connection is used to accommodate the second end 42 of the connecting line 4, the battery 3 can be charged through the second connection port 22, thereby improving the flexibility of the charging method.

[0032] In this embodiment, if Figure 4 The wireless charging component 5 includes a bracket 51, a chassis 52 and a coil 53. The chassis 52 is connected to the circuit board 2 through the bracket 51; the chassis 52 is provided with an annular groove 521, and the annular groove 521 is used to accommodate the coil 53. The design of the annular groove 521 of the chassis 52 can make the chassis 52 equivalent to a magnetic isolation sheet, which can gather magnetic flux and improve the efficiency of wireless charging. Furthermore, the wireless charging component 5 also includes a magnet 54, which is located in the inner circle of the annular groove 521, and the center of the magnet 54 is the same as the axis of the annular groove 521. Adding the magnet 54 can make the watch adsorbed on the charging position 10, so that the induction area of ​​the watch corresponds to the induction coil 11, thereby improving the efficiency of wireless charging.

[0033] In addition, if Figure 1 As shown, the mobile power supply further includes a display screen 6, which is located on the outer surface of the housing 1 and is used to display the power level. Further, the mobile power supply further includes a display control button 7, which is used to control the switch of the display screen 6.

[0034] In this embodiment, if Figure 1The charging position 10 is provided with an extension platform 12, which is located outside the induction coil 11; the extension platform 12 is fixedly connected to the housing 1, and the extension platform 12 is used to contact the first surface of the watch, and is in the same plane as the second surface of the induction coil 11 used to contact the watch. The provision of the extension platform 12 is conducive to better placement of the watch; and making the extension platform 12 and the side of the induction coil 11 that contacts the watch on the same plane is conducive to improving charging efficiency.

[0035] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
