[0029] like Figures 1 to 3 As shown, the projection surface of the charging body 1 of the present embodiment is a rectangular structure, and a retractable first charging seat 3 and a second charging seat 4 are respectively provided on the left and right sides of the charging body 1, wherein the first charging seat 3 and the second charging seat 4 are electrically connected to the battery mechanism in the charging body 1, so that the user can charge the smart watch and the TWS headset respectively through the first charging seat 3 and the second charging seat 4 without cables, thereby realizing the function of wireless charging of multiple commonly used electronic devices at the same time in the present embodiment, expanding the applicable scenarios of the present embodiment, thereby reducing the burden of users carrying when going out and improving the user's experience.

[0030] like Figure 2 and Figure 3 As shown, the first charging seat 3 and the second charging seat 4 of this embodiment can be retracted into the charging body 1 when not charging, which can make the appearance of the charging body 1 more regular, so that it is convenient for users to carry. In order to facilitate the first charging seat 3 and the second charging seat 4 to extend from the charging body 1 when charging is required, this embodiment makes the first charging seat 3 and the second charging seat 4 connected to the magnetic charging mechanism 2 in a transmission manner, so that when the user rotates the magnetic charging mechanism 2, the first charging seat 3 and the second charging seat 4 in the charging body 1 can be driven to automatically extend from the charging body 1, so that the user can charge conveniently.

[0031] like Figure 2 As shown, specifically, the two sides of the charging body 1 of this embodiment on which the first charging seat 3 and the second charging seat 4 are installed are provided with movable channels 11 extending into the charging body 1, and the first charging seat 3 and the second charging seat 4 are respectively movably inserted in the two movable channels 11, so that when the magnetic charging mechanism 2 rotates, the first charging seat 3 and the second charging seat 4 can be driven to move in the movable channel 11, thereby realizing the extension and retraction of the first charging seat 3 and the second charging seat 4.

[0032] In order to realize the transmission connection between the magnetic charging mechanism 2 and the first charging seat 3 and the second charging seat 4, in this embodiment, a rotating groove 12 which is respectively connected to the two active channels 11 is set on the surface of the charging body 1. The magnetic charging mechanism 2 can be rotatably installed in the rotating groove 12 and a transmission gear 7 is set at the bottom. At the same time, one end of the first charging seat 3 and the second charging seat 4 located in the charging body 1 is provided with a transmission rack 6 extending into the active channel 11. The two transmission racks 6 are respectively engaged with the upper and lower sides of the transmission gear 7, so that when the user rotates the magnetic charging mechanism 2, the transmission gear 7 at the bottom thereof can be driven to rotate, so that the two transmission racks 6 move along the active channel 11 under the action of meshing with the transmission gear 7, thereby realizing the extension and retraction of the first charging seat 3 and the second charging seat 4, and the control method is convenient.

[0033] In addition, if Figure 1 and Figure 3 As shown, the outer peripheral edge of the magnetic charging mechanism 2 of this embodiment is also provided with friction lines 21, and the friction lines 21 can increase the friction force, thereby facilitating the user to rotate the magnetic charging mechanism 2 to control the extension and retraction of the first charging seat 3 and the second charging seat 4.

[0034] like Figures 1 to 4 As shown, in order to further reduce the burden of users carrying when going out and improve the user's charging experience, this embodiment also provides detachable expansion batteries 5 on the top and bottom of the charging body 1 respectively. The expansion battery 5 can be connected to the charging body 1, so as to expand the battery capacity of the charging body 1, so that when the user goes out, he can carry a certain number of expansion batteries 5 according to needs to supplement the capacity of the power bank and reduce battery life anxiety; and the expansion battery 5 is small in size and easy to carry; when the user's power demand is low, the expansion battery 5 can also be removed to reduce the user's carrying burden, thereby effectively improving the user's experience.

[0035] Specifically, Figure 2 and Figure 3 As shown, the top and bottom of the charging body 1 of this embodiment are provided with expansion slots 13, and the expansion battery 5 can be inserted into the expansion slots 13 to achieve connection with the charging body 1, thereby expanding the battery capacity of the charging body 1. Among them, one end of the expansion battery 5 of this embodiment is provided with a connecting portion 51 adapted to the expansion slot 13, so that the expansion battery 5 can be connected to the top or bottom of the charging body 1 by inserting the connecting portion 51 into the expansion slot 13, and the connection method is convenient and easy to disassemble.

[0036] In addition, a connection contact 131 electrically connected to the battery mechanism inside the charging body 1 is provided on the bottom plane of the expansion slot 13 of the present embodiment, and a connection contact 131 is also provided on the end surface of the connecting portion 51.

[0040] A rotatable cover plate 8 is also provided on one side of the charging body 1 of this embodiment. When the power bank is not in use, the cover plate 8 can be rotated to cover the surface of the storage slot 14, thereby shielding the charging slot to prevent the charging cable and replacement head in the charging slot from falling off and being lost. When the user uses the power bank of this embodiment to charge, the cover plate 8 can also be rotated to form a bracket, so that the power bank can be supported by the cover plate 8 to form a mobile phone bracket, which is convenient for the user to operate the mobile phone during the charging process, further improving the user's experience.

[0041] In summary, the present invention arranges a magnetic charging mechanism 2 on the surface of the charging body 1, and arranges a movable first charging seat 3 and a second charging seat 4 on the opposite sides of the charging body 1, so that the user can charge the smart phone, smart watch and TWS earphone respectively through the magnetic charging mechanism 2, the first charging seat 3 and the second charging seat 4 without cables, and the charging method is convenient and easy to carry; and by arranging a rotatable magnetic charging mechanism 2, and making the first charging seat 3 and the second charging seat 4 transmission connected with the magnetic charging mechanism 2, the user can control the extension and retraction of the first charging seat 3 and the second charging seat 4 by rotating the magnetic charging mechanism 2, so that the user is convenient to carry; at the same time, by arranging a detachable expansion battery 5 at both ends of the charging body 1, the user can carry an additional expansion battery 5 according to needs when going out to expand the capacity of the power bank, reduce power anxiety and improve convenience, thereby improving the user experience.
