[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figures 1 to 5As shown, a portable power bank includes a power supply 1 and an expansion power supply 2 magnetically disposed below the power supply 1. The power supply 1 is equipped with a storage and interaction mechanism 31 and a multi-position limiting mechanism 32. The storage and interaction mechanism 31 includes a drive gear 312 disposed inside the power supply 1. A power cord 311 is wound up below the drive gear 312. A record turntable 318 is disposed at the top of the power supply 1. The winding and storage of the power cord 311 increases its ease of use and portability. The record turntable 318 is used to enhance the visual interaction with the user. The multi-position limiting mechanism 32 includes a limiting groove 321 disposed on the drive gear 312. A limiting block 323 is disposed on the limiting groove 321. The limiting groove 321 and the limiting block 323 can be used to position the length of the power cord 311 in multiple positions.

[0019] Furthermore, the storage and interaction mechanism 31 includes a second support frame 3112 disposed on the bottom of the inner wall of the power supply 1. The drive gear 312 is rotatably disposed on the inner wall of the second support frame 3112. A coil spring 313 is connected to the bottom of the inner wall of the second support frame 3112. One end of the coil spring 313 is connected to the inner wall of the drive gear 312. The drive gear 312 is meshed with a first gear 314. The bottom end of the first gear 314 is rotatably disposed on the second support frame 3112. The first gear 314 is meshed with a second gear 315. The second gear 315 is meshed with a third gear 316. The third gear 316 is meshed with a driven gear 317. A record turntable 318 is connected to the top of the driven gear 317.

[0020] Furthermore, a charging head 319 is connected to the end of the power cord 311 away from the drive gear 312. A first support frame 3110 is connected to the upper end of the inner wall of the power supply 1. A first groove 3111 is opened at the bottom end of the first support frame 3110. A second groove 3113 is opened at the bottom end of the second support frame 3112. The outer walls of the upper and lower ends of the second gear 315 are movably disposed on the inner walls of the first groove 3111 and the second groove 3113.

[0021] Furthermore, the bottom end of the second gear 315 is in contact with the top surface of the drive gear 312, so that when the drive gear 312 rotates, it can drive the second gear 315 in contact with it to move by friction, thereby making the record turntable 318 rotate only in the forward direction.

[0022] The multi-position limiting mechanism 32 includes a connecting plate 322 connected to the bottom of the first support frame 3110, a limiting block 323 whose top end is connected to the bottom end of the connecting plate 322, and a limiting block 323 whose top end is movably engaged with the inner wall of the limiting groove 321.

[0023] Furthermore, the limiting slot 321 is multi-layered, and the number of limiting blocks 323 corresponds to the number of limiting slots 321 and is slidably disposed on its inner wall, thereby enabling multi-level adjustment and improving the practicality of the equipment.

[0024] Furthermore, the inner wall of the limiting slot 321 fits snugly against the outer wall of the limiting block 323, thereby improving the tight fit between the limiting block 323 and the limiting slot 321, and thus improving the stability of the snap-fit ​​positioning.

[0025] The implementation principle of a portable power bank in this embodiment is as follows: By winding the charging cable 311 under the drive gear 312, the charging cable 311 can be wound up, making it easy to store. This increases portability and also increases the length of the power cable 311, thereby improving daily practicality. When charging is needed, the charging head 319 is pulled outward, causing it to extend the charging cable 311. As the charging cable 311 is extended, it drives the drive gear 312 to rotate. During the rotation of the drive gear 312, the coil spring 313 will rotate. Rotation will drive the first gear 314 on one side to rotate. At the same time, during the rotation of the driving gear 312, the second gear 315, which is attached to its top, will slide in the first groove 3111 and the second groove 3113, thereby causing the second gear 315 to mesh with the first gear 314. In this way, the rotation of the first gear 314 will drive the second gear 315 to rotate. The rotation of the second gear 315 will drive the third gear 316 to rotate, which in turn drives the driven gear 317 to rotate. As the driven gear 317 rotates, it will drive the record turntable 318 at the top to rotate, thus creating visual interaction with the user during use and increasing the fun. When the power cord 311 is not in use, the coil spring 313 rebounds and rotates, thereby driving the drive gear 312 to rotate and retract the power cord 311. At the same time, during the rotation of the drive gear 312, the second gear 315 will slide between the inner wall of the first groove 3111 and the inner wall of the second groove 3113, thereby disengaging the second gear 315 from the first gear 314. In this way, the record turntable 318 will not be driven to reset and rotate during the retraction of the power cord 311, so that the record turntable 318 will only rotate in the forward direction when the user uses the power cord 311.

[0026] During the rotation of the drive gear 312, the limiting groove 321 in the center will be rotated synchronously. During the rotation of the limiting groove 321, it can be used in conjunction with the limiting block 323 at the bottom of the connecting plate 322 to enable the positioning of the power cord 311 in multiple lengths, thereby further improving portability and ease of use.
