[0018] Beneficial effects
[0019] Compared with the prior art, this utility model provides a convenient electric scooter battery device, which has at least the following advantages:
[0020] 1. The battery pack casing is secured by a fixing mechanism. Two locking blocks extend to the left and right sides of the fixing frame to secure the casing. These blocks are further reinforced by toothed plates, trapezoidal blocks, telescopic rods, a third spring, and a fixing sleeve, ensuring stability during fixing. Disassembly is achieved by manually pulling the battery pack casing upwards. The two locking blocks retract into the fixing frame under external force, allowing the casing to be removed.

[0037] Example 2
[0038] like Figure 1-Figure 5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the extrusion mechanism 3 includes an extrusion plate 37, a groove is provided on the left side of the battery pack shell 1, a sliding block 34 is slidably arranged on the inner wall of the groove, a support plate 35 is hinged to the left side of the sliding block 34, the left side of the support plate 35 is hinged to the right side of the extrusion plate 37, an extrusion pad 38 is fixedly arranged on the right side of the battery pack shell 1, a support connecting rod 36 is fixedly arranged on the right side of the extrusion plate 37, the right side of the support connecting rod 36 is fixedly connected to the inner wall of the groove, a first spring 31 and a damper 32 are fixedly arranged on the inner wall of the groove, the bottom surface of the first spring 31 and the bottom surface of the damper 32 are both fixedly connected to the top surface of the sliding block 34, a guide groove is provided on the back of the sliding block 34, a guide rail 33 is fixedly arranged on the inner wall of the groove, and the surface of the guide rail 33 is slidably connected to the inner wall of the guide groove.
[0039] In this embodiment, the compression mechanism 3 can be provided to compress and support the battery pack shell 1 during installation, making the battery pack shell 1 more stable when installed inside the electric scooter.

After the sliding block 34 is compressed, the support plate 35 can support the compression plate 37, thereby supporting the battery pack shell after installation and increasing its stability.
[0040] In use, the battery pack casing 1 is installed inside the electric scooter. After installation, the sliding block 34 is pressed by the first spring 21 and the damper 32. After the sliding block 34 is pressed, the pressing plate 37 is supported by the support plate 35, thus supporting the battery pack casing 1 after installation and increasing its stability. When the bottom of the battery pack casing 1 moves downward, the fixing frame 41 moves downward. When the fixing frame 41 moves downward, the pressing rod 44 moves downward synchronously. After the bottom surface of the pressing rod 44 contacts the inside of the electric scooter, it moves upward. When the pressing rod 44 moves upward, it drives the lifting block 43 to move upward. When the lifting block 43 moves upward, it drives the pressing block 47 to move upward. When the pressing block 47 moves upward, it moves the two inclined blocks 48 to the sides. When the two inclined blocks 48 move to the sides, it drives the two moving plates 45 to move synchronously. When the two moving plates 45 move to the sides, they drive the two locking blocks 4... 2. The two locking blocks 42 move synchronously. When the two locking blocks 42 move left and right, they can extend to both sides of the fixed frame 41. After the two locking blocks 42 extend, the battery pack 1 can be fixed. After the two locking blocks 42 extend, they can be reinforced by the toothed plate 416, trapezoidal block 417, telescopic rod 418, third spring 420 and fixed sleeve 421. When it is necessary to disassemble the battery pack shell 1, simply pull the battery pack shell 1 upward manually. When pulling upward, the two locking blocks 42 will retract into the fixed frame 41 after being subjected to external force, so that the battery pack shell 1 can be removed. When the battery pack shell 1 moves upward, the elastic element 411 can make the pressing rod 44 move downward. When the pressing rod 44 moves downward, it can drive the pressing block 44 to move downward synchronously. After the pressing block 44 moves downward, the elastic sheet 414 can make the moving plate 45 move closer to each other, so that the two locking blocks 42 can retract into the fixed frame 41 when no external force is applied.
