This not only affects the user experience but also limits the application of smartwatches in scenarios that require continuous operation for extended periods.
[0004] To address the issue of insufficient battery life in smartwatches, the industry has conducted extensive research and exploration. Traditional solutions often involve increasing battery capacity to improve battery life, but this method is limited by the size and weight of smartwatches, making significant improvements difficult. Furthermore, excessively large battery capacities can increase charging time, reduce charging efficiency, and may even pose safety risks.
[0005] Therefore, we need to design a charging case for smartwatches to extend their battery life. Utility Model Content

[0007] A smartwatch charging case includes a charging case body, a wireless charging magnetic coil, a USB port, a charging port, and a square opening. The wireless charging magnetic coil is embedded in the upper part of the charging case body. The charging port and the USB port are symmetrically arranged on the left side of the charging case body. The square openings are symmetrically arranged on the front and back sides of the charging case body. The case also includes a battery life component, which is located on the top of the charging case body.
[0008] Furthermore, the battery life component includes a magnetic block, an elastic cord, and a second charging case. The second charging case is magnetically connected to the top of the first charging case. A charging port and a USB port are symmetrically arranged on the left side of the second charging case. Square openings are also symmetrically arranged on the front and back sides of the second charging case. A wireless charging magnetic ring is also embedded in the upper part of the second charging case. A magnetic block is located at the center of the right side of both the first and second charging cases. The right sides of the first and second charging cases are connected by an elastic cord.
[0009] Furthermore, it also includes a limiting cylinder, which is embedded in the square opening.
[0010] Furthermore, it also includes a limiting cylinder, and a limiting plate is slidably provided inside the limiting cylinder.
[0011] Furthermore, it also includes indicator lights, which are installed on both the first and second charging case bodies.
[0012] Furthermore, an anti-slip pad is provided on the inner side of the limiting plate.
[0013] The beneficial effects and significant advancements of this utility model are as follows:
[0014] This invention employs a unique magnetic connection design between the charging case body one and the charging case body two, allowing for flexible separation and combination. This design not only enhances the structural stability of the charging case but also allows users to quickly and conveniently replace the two bodies when needed. When one body runs out of power, the user does not need to worry about being unable to continue charging the smartwatch, thus effectively improving the charging case's battery life and user experience.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] Example: A charging case for extending the battery life of a smartwatch. Please see below. Figures 1 to 3 As shown, the device includes a charging case body 1, a wireless charging magnetic coil 2, a USB port 3, a charging port 4, an indicator light 5, a square opening 51, a magnetic block 6, an elastic cord 7, a second charging case body 8, a limiting plate 9, and a limiting cylinder 10. The wireless charging magnetic coil 2 is embedded in the upper part of the charging case body 1, providing wireless charging for the smartwatch. The charging port 4 and USB port 3 are symmetrically arranged on the left side of the charging case body 1, for connecting to an external power source or data cable to provide power input to the charging case. The charging case body 1 is equipped with indicator lights 5 to display the charging status, such as charging in progress or fully charged, allowing users to easily monitor the charging progress. Square openings 51 are symmetrically arranged on the front and back sides of the charging case body 1. A second charging case body 8 is magnetically connected to the top of the charging case body 1. A charging port 4 and a USB port 3 are symmetrically arranged on the left side of the second charging case body 8. The second charging case body 8 also has indicator lights 5 and symmetrically arranged square openings 51 on its front and back sides. A wireless charging magnetic coil 2 is also embedded in the upper part of the charging case 8. A magnetic block 6 is connected to the center of the right side of both the charging case body 1 and the charging case body 2. The right sides of both charging case body 1 and the charging case body 2 are connected together by an elastic cord 7. The elastic cord 7 provides additional connection force, ensuring that they remain closed when not pried apart, and also increases ease of use. To use, simply separate the charging case body 1 and the charging case body 2 and place them on a flat surface. The charging case body 1 and the charging case body 2 can then be used. After placement, the charging case body 1 and the charging case body 8 can be attracted together by two magnetic blocks 6. Limiting cylinders 10 are embedded in the square opening 51. Limiting plates 9 are slidably connected between the internal parts of the limiting cylinders 10. By sliding the limiting plates 9, the position of the limiting plates 9 can be adjusted. When the smartwatch is charging, the smartwatch wristband can be threaded onto the limiting plates 9. The limiting plates 9 limit the smartwatch and prevent it from slipping or moving during charging. The inner side of the limiting plates 9 is equipped with anti-slip pads to prevent the smartwatch wristband from slipping.
[0021] When the charging case is needed to charge the smartwatch, its main structure consists of charging case body 1 and charging case body 2 8. The charging process is very simple: just place the smartwatch on charging case body 2 8, and the internal wireless charging magnetic coil 2 will automatically charge the smartwatch. Simultaneously, the smartwatch's wristband can pass through the limiting plate 9, whose design effectively prevents the smartwatch from slipping or moving during charging.
[0022] During charging, indicator light 5 clearly displays the charging status of the charging case, such as charging in progress or fully charged, allowing users to monitor the charging progress at any time. In addition, the charging case is equipped with a USB port 3 and a charging port 4, both of which can be used to connect an external power source or data cable to provide power input to the charging case.
[0023] Due to its compact size and portable design, this charging case is ideal for carrying around. Its unique magnetic connection design allows the charging case body 1 and charging case body 2 to be flexibly separated and combined. When one body runs out of power, the other can be used instead, thus extending the charging case's battery life. When needed, the user simply pries the charging case body 2 8 off the charging case body 1 with gentle force and then lays both flat on a surface. Thanks to the ingenious design of the magnet 6, the charging case body 1 and charging case body 2 8 can be securely attached together, providing great convenience for subsequent charging of the smartwatch.
