In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] Please refer to Figure 1-6 As shown, a novel pull-out power bank structure includes a battery shell 1 and a box cover 2 connected to the upper port of the battery shell 1. The battery shell 1 and the box cover 2 form a wine bottle structure style. By setting the combination of the battery shell 1 and the box cover 2 as a wine bottle structure style, the diversity of the appearance of the power bank structure can be improved, which is more conducive to being favored by the user group, and the performance of promotion and use is better and it is more convenient to carry.
[0026] A magnetic column A11 is provided on the upper shell port of the battery shell 1, and a magnetic column B21 opposite to the magnetic column A11 is provided on the cover plate port of the box cover 2, and the magnetic column B21 is attracted to the magnetic column A11. By utilizing the magnetic attraction between the magnetic column B21 and the magnetic column A11, the opening and closing of the box cover 2 and the battery shell 1 can be made more stable, avoiding the situation of loosening after the cover is closed.
[0027] A display screen 4 which is conductively connected to the pull-out cable assembly 3 is installed through the inner wall of the battery shell 1. The body of the battery shell 1 is provided with a transparent protective cover which covers the display screen 4. By providing a transparent protective cover opposite to the display screen 4 on the body of the battery shell 1, the display screen 4 is protected and covered, and it is convenient for the user to intuitively observe the power status on the display screen 4.
[0028] The upper half of the chamber of the battery shell 1 is provided with a pull-out cable assembly 3, and the lower half of the chamber of the battery shell 1 is provided with a storage battery 5. The pull-out cable assembly 3 includes a winding shell 31 and a main control panel 33 installed on the shell port of the winding shell 31. The circuit board of the main control panel 33 is connected with a Hall switch module 34. The shell of the winding shell 31 is rotatably connected with a winding rack 35. A conductive panel 36 connected to the main control panel 33 is installed on one side of the reel of the winding rack 35. A charging line 37 connected to the conductive panel 36 is wound inside the reel of the winding rack 35. The other end of the cable of the charging line 37 is connected to the conductive panel 36. A charging head 32 is connected, and an induction magnet 38 is installed on one side of the reel of the winding frame 35 and near the tail line of the charging line 37. The induction magnet 38 passes through the Hall switch module 34 along the winding direction of the charging line 37. When the charging line 37 is pulled out of the battery shell 1, it drives the winding frame 35 to rotate along the axis of the winding shell 31. While the winding frame 35 rotates, it drives the induction magnet 38 to rotate synchronously, and passes near the Hall switch module 34 to generate a trigger signal, which is transmitted to the main control panel 33. The main control panel 33 is used to control the display screen 4 to light up and display the remaining power.
[0029] The central axis of the winding shell 31 is wound with a spring 39 connected to the winding frame 35, and the winding frame 35 is elastically rotatably connected to the winding shell 31 through the spring 39. When the charging line 37 on the winding frame 35 is wound and pulled out, the winding frame 35 drives the spring 39 to tighten synchronously. Then, when charging is completed, the spring 39 is tensioned and reset to push the winding frame 35 to elastically reverse, and the combination of the charging line 37 and the charging head 32 is autonomously wound into the battery shell 1. It occupies less space and is more stable to be wound, which is convenient for users to carry and use.
[0030] The working principle of the utility model is as follows: when the user needs to check the remaining power of the power bank during the process of using the power bank, after opening the box cover 2, the combination of the charging head 32 and the charging line 37 is pulled out from the winding frame 35 inside the battery shell 1, and the synchronous winding frame 35 rotates while driving the induction magnet 38 to rotate synchronously, and passes close to the Hall switch module 34 to generate a trigger signal, and the trigger signal is transmitted to the main control panel 33, and the main control panel 33 is used to control the display screen 4 to light up and display the remaining power. It can display the remaining power without connecting to the charging device, and the operation is more convenient. When charging is performed subsequently, the combination of the charging line 37 and the charging head 32 is pulled out, and the charging head 32 is connected to the charging interface of the electronic product device to perform the charging work. After charging is completed, it is only necessary to pull out the charging head 32, and the tension of the spring 39 is used to reset, and the winding frame 35 is pushed to elastically reverse, and the combination of the charging line 37 and the charging head 32 is automatically wound into the battery shell 1, and no manpower is required to store it. The operation is simpler and more convenient, and the space occupied is smaller, which is more convenient for users to carry and use.
[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
