[0002] An electric bicycle refers to a mechatronic vehicle that uses a storage battery as an auxiliary energy source and is installed with a motor, a controller, a storage battery, a throttle grip, a brake lever and other control components and a display instrument system on the basis of an ordinary small vehicle. Due to its economic and convenient advantages, it is widely used, and because it uses clean energy, it is not restricted in the city.

[0003] During the use of an electric bicycle, the biggest problem is charging. Therefore, the structure of the entire battery box needs to be convenient for quick disassembly, handling, and have a certain degree of safety to avoid being easily lost. However, when the user takes the battery box, since there is no convenient handle structure on the battery box, it is inconvenient for the user to take the battery box, and the battery box is likely to fall, thus affecting the performance and service life of the battery cells inside the battery box.

[0004] At the same time, the LEC lamp ring of the traditional battery pack is exposed outside the battery pack, and its appearance looks disharmonious, affecting the beauty of the battery pack. Summary of the Invention

[0005] The utility model aims to overcome the deficiencies of the prior art and provides a structure of a portable battery pack, which adds a handle structure to the battery pack, facilitating the taking of the battery pack during disassembly and handling. At the same time, it solves the problems of exposed screw holes and large space occupation of the display lamp ring.

[0006] To achieve the above object, a structure of a portable battery pack is designed, including an aluminum shell, a PCB lamp ring, an upper cover, and a handle structure. The characteristics are as follows: the top of the aluminum shell is connected to the upper cover through a plurality of upper shell fixing screws, a plastic plate is provided on the top of the upper cover, a handle structure is provided above the upper cover, and the left and right ends of the handle structure are respectively connected to the upper cover by handle fixing screws; a PCB lamp ring is provided between the top of the upper cover and the aluminum shell.

[0007] An inner embedded steel belt is provided inside the handle structure.

[0008] The handle structure is one of a C-shaped, trapezoidal, or rectangular frame structure.

[0009] The plastic plate is a plastic plate with a black adhesive backing.

[0010] The upper cover is a stepped cover plate structure, and a protruding buckle for connecting the PCB lamp ring is provided on the outer edge of the bottom of the upper cover.

[0011] The upper cover is a milky white translucent cover plate.

[0012] A PCB board is provided in the middle of the PCB lamp ring, and the PCB board is connected to the upper cover by PCB board fixing screws. One end of the silicone button is connected to the top of the PCB board, and the other end of the silicone button penetrates through the upper cover and the plastic board and is located on the upper side of the plastic board.

[0013] The bottom of the aluminum outer shell is connected to the lower shell by bolts.

[0014] Compared with the prior art, the present utility model provides a portable battery pack structure, which adds a handle structure to the battery pack, facilitating the taking of the battery pack during disassembly and handling. At the same time, it solves the problems of exposed screw holes and large space occupation of the display lamp ring. BRIEF DESCRIPTION OF THE DRAWINGS
