[0027] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0028] Existing mobile power supplies are generally charged in the form of wired connections, and are often unable to charge multiple devices at the same time. In addition, due to size limitations, they generally only have one wireless charging position, which is mainly used for wireless charging of mobile phones, and do not have a charging position that can simultaneously accommodate watches and wireless headphones. With the popularization of wireless wearable devices and the corresponding charging needs, a mobile power supply with better applicability is needed.

[0029] like Figure 1 , 2As shown in , 7 , the utility model proposes a foldable mobile power supply, including: a main shell 1, a left shell plate 2, a right shell plate 3, a mobile phone wireless charging coil, a watch wireless charging coil, an earphone wireless charging coil, a mainboard 4 and a plurality of batteries 5. The main shell 1 is in the shape of a rectangular parallelepiped, which is consistent with the appearance of a conventional mobile power supply. A mobile phone wireless charging position 11 is provided on the front of the main shell 1, and hinge seats are respectively provided near the edges of both ends on the back. The hinge seats can also serve as supporting feet when the main shell 1 is placed with the front side facing up; the left side shell plate 2 is rotatably connected to the left end of the main shell 1, and an axle seat is provided on the left side shell plate 2 to cooperate with the hinge seat. When the left side shell plate is rotated to 0°, the front side is fitted with the left area of ​​the back side of the main shell 1, that is, the front side faces up and the back side faces down. When the left side shell plate 2 is rotated to 180°, it is located outside the left end of the main shell 1. At this time, the front side of the left side shell plate 2 faces down and the back side faces up, and a watch wireless charging position 21 is provided on the back side of the left side shell plate 2, that is, after the left side shell plate 2 is opened outward, its watch wireless charging position 21 faces up, and at the same time, the mobile phone wireless charging position 11 of the main shell 1 also faces up, so that the mobile phone and the watch can be wirelessly charged at the same time; the right side shell plate 3 is rotatably connected to the right end of the main shell 1, and the right side shell plate 3 is An axle seat and an articulated seat are also provided. When the right shell plate 3 is rotated to 0°, the front face fits with the right area of ​​the back of the main shell 1, that is, the front face is upward and the back face is downward. When the right shell plate 3 is rotated to 180°, it is located outside the right end of the main shell 1. At this time, the front face of the right shell plate 3 faces downward and the back face faces upward, and a headset wireless charging position 31 is provided on the back of the right shell plate, that is, after the right shell plate 3 is opened outward, its headset wireless charging position 31 faces upward, and at the same time, the mobile phone wireless charging position 11 of the main shell 1 and the headset wireless charging position 21 of the left shell plate 2 are also facing upward, so that the hands, headsets and watches can be wirelessly charged at the same time; the mobile phone wireless charging coil is arranged on the main shell corresponding to the mobile phone wireless charging position, the watch wireless charging coil is arranged on the left shell plate corresponding to the watch wireless charging position, and the headset wireless charging coil is arranged on the right shell plate corresponding to the headset wireless charging position; the mainboard 4 and the battery 5 are arranged inside the main shell, and the mainboard is electrically connected to the battery and each wireless charging coil.

[0030] The foldable mobile power supply proposed by the utility model directly arranges two shell plates that can be flipped outward and opened on the back of the main shell body, and arranges wireless charging coils on the front of the main shell body and the back of the two shell plates, so that the mobile power supply can charge multiple wireless charging devices at the same time, and is very flexible to use. If it is necessary to charge a watch, a mobile phone and an earphone at the same time, the shell plates on both sides are opened; if only two devices need to be charged, only one side of the shell plate can be opened. At the same time, since the shell plate is mainly used to charge small electronic devices with a small charging power, the coil size is small, and the shell plate can be designed to be light and thin, so that the overall thickness of the entire mobile power supply will not be too thick when the two shell plates are folded, and it is convenient to move and carry.

[0031] In a specific embodiment, the front of the main shell 1 is rectangular, and the mobile phone wireless charging position 11 is arranged near the left side of the main shell 1. At the same time, a ring-shaped permanent magnet (not shown in the figure) is also provided in the main shell, and the permanent magnet is arranged around the mobile phone wireless charging coil.

[0032] like Figure 3 , 4 As shown, since there is a certain damping between the rotation of the shell plate and the main shell 1, the left shell plate 2 and the right shell plate 3 can be used as legs to tilt the main shell 1. For example, the left end can be tilted higher and the right end can be lower. The left shell plate 2 at the left end can be vertical to the ground as a leg, and the right shell plate 3 at the right end can be close to the back of the main shell 1 or close to the bottom as another leg, so that the main shell 1 is in a stable tilted state, and the tilt angle of the main shell 1 can be adjusted by adjusting the tilt angle of the left shell plate 2. The mobile phone can be fixed to the main shell by magnetic fixation and is in a tilted state. At this time, the mobile power bank can be used as a wireless charging stand.

[0033] In order to improve the support stability, the left edge of the left shell plate and the right edge of the right shell plate can also be covered with anti-slip edging. The anti-slip edging can play a supporting effect when the mobile power supply is used as a bracket or placed directly on the desktop. The anti-slip edging can specifically be an anti-slip cover with grooves that is sleeved on the outer ends of the left shell plate and the right shell plate, and the grooves correspond to the end faces of the shell plates.

[0034] like Figure 5 , 6 As shown, in a specific embodiment, the hinge seats 13 at both ends of the main shell 1 are in the shape of long strips and are provided with axial holes along the length direction, and a rotating shaft 6 is installed at the axial holes. Two axial seats 22 are respectively extended from the two sides close to the connection side of the left shell plate 2 and are sleeved on the parts of the rotating shaft 6 extending from the axial holes, so that the left shell plate 2 is rotatably connected to the main shell 1, and the connection method of the right shell plate is the same as that of the main shell.

[0035] Specifically, in order to improve the damping effect, a damping plate 7 sleeved on the rotating shaft is provided between the hinge seat 13 and the shaft seat 22. The damping plate 7 is provided with a plurality of arc-shaped protrusions on both sides facing the hinge seat 13 and the shaft seat 22, respectively. At the same time, concave holes corresponding to the arc-shaped protrusions are provided on the side surfaces of the damping plates corresponding to the hinge seat and the shaft seat, so that there is a damping feeling when the two shell plates rotate, and they can be rotated to a position between 0° and 180° and stabilized.

[0036] In a specific embodiment, non-slip silicone is laid on the wireless charging position of the watch and the wireless charging position of the earphone to prevent the wireless charging device from sliding and affecting the alignment of the wireless charging coil.

[0037] like Figure 7As shown, specifically, a cover plate 12 is provided on the front side of the main housing 1, and a USB port and a type-c port corresponding to the mainboard are provided on the rear side (not shown), and the cover plate 12 is fixed to the main housing 1 by gluing and sealing, thereby sealing the inside of the main housing 1. The mainboard 4 and four cylindrical batteries 5 (lithium batteries) are installed in the main housing.

[0038] Specifically, the mobile phone wireless charging coil can be installed in the main housing, and can be pasted on the inner side of the front of the main housing. The back of the left shell plate and the right shell plate are provided with mounting grooves, and the watch wireless charging coil and the earphone wireless charging coil are respectively installed in the corresponding mounting grooves, and the notch of the mounting groove is covered with a decorative cover plate covering the charging coil to prevent the coil from being directly exposed.

[0039] In addition, the connecting wires between the left shell plate and the right shell plate can enter the main shell body from the position of the shaft seat. Specifically, a wire passing hole is set inside the shaft seat, and a wire passing hole is also set on the back side of the main shell body opposite to the shaft seat, so that the connecting wires of the watch wireless charging coil and the earphone wireless charging coil can be connected to the inside of the main shell body and the mainboard through the wire passing hole. The specific wire passing method is also very common in the prior art and will not be elaborated on.

[0040] In addition, the specific circuit structure of the mainboard is very common in existing mobile power supplies and is not the focus of the present invention, so it will not be described in detail.
