The power bank body 1 is arranged on the movable plate 3, and the movable plate 3 is hinged on the base 2 to form a foldable bracket structure for holding a mobile phone. In order to achieve the purpose proposed by the utility model, wheel-like supporting feet 21 are respectively provided at both ends of the base 2, and an overhead bottom cavity 23 conducive to heat dissipation is also formed on the bottom surface of the base 2 located between the two wheel-like supporting feet 21; the wheel-like supporting feet 21 are hollow cavity structures, and LED light-emitting components are also arranged in the hollow cavity structure. A light-transmitting window 22 for projecting light that is connected to the hollow cavity structure is also provided on the wheel-like supporting feet 21. The utility model uses the structural design of lifting the base 2 into the air by means of the wheel-like supporting feet 21, which helps to allow air to flow through the bottom surface of the base 2, improves the heat dissipation performance, and ensures that the mobile power supply device has a very good service life. In addition, the wheel-like supporting feet 21 on both sides can form an eight-shaped placement support structure, so that it can be placed stably on the desktop, thereby ensuring the safety of the mobile phone when the mobile power supply device is placed for charging or use. At the same time, the lighting function provided on the mobile power supply device can not only increase the practicality of the product, so that it can also be used as a night light, but also use lighting decoration to make it appear in working state during the charging process, thereby increasing the recognition of product application, improving the product grade, and increasing the market competitiveness of the product.

[0019] In order to further improve the structure of the wheel-shaped support foot 21, making it simple and easy to implement, as shown in FIG. Figure 4 As shown, the wheel-shaped support foot 21 includes a strip-shaped columnar portion 211 and end cap portions 212 disposed at both ends of the strip-shaped columnar portion 211, and the strip-shaped columnar portion 211 is a hollow cavity structure. The arrangement of the strip-shaped columnar portion 211 not only ensures the stability of its placement, but also has a simple structure and a simple shape, and is very easy to implement. The arrangement of the end cap portion 212 can prevent dust or debris from entering the strip-shaped columnar portion 211, thereby avoiding affecting the use of the LED light-emitting component, and can also prevent people's hands from touching the LED light-emitting component, thereby improving the safety of use.

[0020] like Figure 2 As shown, the outer side of the strip-shaped columnar portion 211 is also provided with an arc-shaped cover 213 covering the surface thereof, and the light-transmitting window 22 is provided on the front side of the arc-shaped cover 213. By providing the arc-shaped cover 213, not only the outer side of the strip-shaped columnar portion 211 can be covered and protected, its structural strength can be increased, and its anti-collision performance can be improved, but also the light-transmitting window 22 is provided on the front side, which can make the illumination of the light brighter and more conspicuous. At the same time, the arc-shaped cover 213 can further highlight the wheel-shaped structure of the wheel-shaped support foot 21, so as to increase the uniqueness of the shape, improve the recognition of product application, enhance the product grade, and increase the market competitiveness of the product.

[0021] In order to make the light refract more softly and not glaring, it can also add unique lighting effects, such as Figure 4 As shown, a light-transmitting strip 25 is also provided on the inner side of the strip-shaped columnar portion 211. In this way, the light of the LED light-emitting assembly can first illuminate the bottom surface of the entire base 2, and then be refracted through the arc surface of the wheel-shaped support foot 21.

[0022] like Figure 2 As shown, the base 2 includes a main body 202 with an integrally formed concave groove 201, and an arc-shaped side skirt cover 203 arranged on both sides of the main body 202. By setting the concave groove 201, the space of the thickness of the base 2 can be fully utilized to accommodate the movable plate 3 and the power bank body 1, so that the overall thickness of the mobile power device will not be too thick. At the same time, the wall thickness of the base 2 is narrowed, which is conducive to heat dissipation. The arc-shaped side skirt cover 203 can improve the hand feel of the mobile power device when it is held and will not be resting on the hand. On the other hand, it is conducive to enriching the functional shape of the product. The arc-shaped side skirt cover 203 is matched with the wheel-shaped support foot 21 to form a car-shaped structure, so that the structure of the mobile power device will not be too dull, and it has an innovative and recognizable functional structure to increase the uniqueness of the shape, improve the recognition of product application, improve the product grade, and increase the market competitiveness of the product.

[0023] like Figure 2 As shown, one end of the movable plate 3 is hinged in the concave groove 201 so that the movable plate 3 can be folded downward and embedded in the concave groove 201, and the other end of the movable plate 3 is provided with a handle 31 for conveniently lifting the movable plate 3 upward from the concave groove 201. In this way, the overall thickness of the mobile power supply device will not be too thick, and at the same time, it is also convenient to lift and unfold the movable plate 3.

[0024] In order to make the power bank body 1 detachable for use separately, the flexibility of the mobile power supply device and the portability of carrying it out are improved. Figure 2 and Figure 3 As shown, a power bank embedding groove 30 is provided on the movable plate 3 , and the power bank body 1 is detachably embedded in the power bank embedding groove 30 .
