Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to a charger that is easy to store. Background Technology

[0002] With the widespread use of portable electronic devices, chargers have become an indispensable accessory in people's daily lives. However, traditional chargers present many inconveniences in terms of carrying and storage. On the one hand, charging cables are usually long, and if not properly coiled after use, they are prone to tangling and knotting, which not only affects the appearance but also increases the difficulty of storage and may even damage the charging cable. On the other hand, the charger prongs are usually a fixed structure, extending when in use and remaining extended when not in use. This makes it easy for the charger to scratch other items when placed in a bag or pocket, or to be damaged due to improper force on the prongs. It also increases the size of the charger itself, making it inconvenient to carry. Utility Model Content

[0020] like Figures 1-6 The charger shown includes a housing 1 and a control board 2 disposed inside the housing 1. The housing 1 has a cuboid structure. A reel 3 connected to the control board 2 is provided inside the housing 1. A reel 4 for winding is provided inside the reel 3. A lead-in port 100 is provided on the front side of the housing 1. A charging connector 41 extending out of the lead-in port 100 is provided at the outer end of the charging cable 4. A pin 5 is provided on the bottom surface of the housing 1. A pin receiving groove 122 is provided on the bottom of the housing 1 corresponding to the pin 5. A connecting seat 21 is provided on the control board 2. The pin 5 is rotatably connected to the connecting seat 21. The pin 5 is electrically connected to the control board 2 through the connecting seat 21. When the pin 5 is perpendicular to the bottom surface of the housing 1, the lower end of the pin 5 extends beyond the bottom surface of the housing 1. When the pin 5 is rotated to be parallel to the bottom surface of the housing 1, the pin 5 is completely accommodated in the pin receiving groove 122.

[0021] The outer casing 1 includes a shell 11 and a cover 12. The rear end of the shell 11 is provided with an opening 111, and the rear end of the bottom surface of the shell 11 is provided with a notch 112 that communicates with the opening 111. The lower end of the cover 12 is provided with a pin seat 121, and a pin receiving groove 122 is provided on the pin seat 121. When the cover 12 is connected to the shell 11, the cover 12 closes the opening 111, and the pin seat 121 closes the notch 112. The inner wall of the opening 111 is provided with a stepped surface 113, and a limiting protrusion 114 is provided on the stepped surface 113. The inner wall edge of the cover 12 is provided with an eave 123, and a limiting groove 124 is provided on the eave 123 corresponding to the limiting protrusion 114. The connecting seat 21 is provided with a connecting member 211, and the connecting member 211 is provided with a plurality of limiting holes 212. The axis of the limiting holes 212 is distributed parallel to the cover plate. The plug seat 121 is provided with a limiting post 125 on the side facing the connecting member 211, which is adapted to the limiting hole 212. When the limiting post 125 is inserted into the limiting hole 212, the cover plate is inserted into the opening 111 from bottom to top, and the limiting protrusion 114 is engaged in the limiting groove 124. The outer shell adopts a split snap-fit ​​design, which makes the installation and maintenance of the internal components more convenient. On the other hand, the snap-fit ​​design makes the whole structure more aesthetically pleasing, and there is no need to install bolts or other fasteners on the outside.

[0022] A magnet 6 is provided on the inner wall of the front side of the outer casing 1, below the lead wire opening 100. When the charging cable 4 is wound up by the reel 3, the charging connector 41 is attracted by the magnet 6 when it bends downward. After the charging cable is wound into the reel, the charging connector is exposed outside the casing. The charging connector bends downward and is attracted and positioned by the magnet, thereby preventing the charging connector from shaking or accidentally protruding when stored, further improving the neatness of storage.

An annular boss 72 protrudes outward and embeds into the lead-in port 100 at the edge of the clearance hole 71. The inner wall of the annular boss 72 has rounded corners. The connecting piece effectively increases the strength at the lead-in port, while the annular boss and rounded corners effectively reduce friction when the charging cable enters and exits the lead-in port, thereby extending the lifespan of the charging cable and providing a smoother experience when unplugging the charging cable.

[0024] like Figure 6As shown, the reel 3 is provided with several connecting posts 31, and the end of each connecting post 31 is provided with a threaded hole 311. The control plate 2 is provided with a through hole 200 corresponding to the connecting post 31, and the through hole 200 and the threaded hole 311 are bolted together. One of the connecting posts 31 is located inside the lead-in port 100, and the charging cable 4 is led out from the lead-in port 100 after passing over the upper side of the connecting post 31. The reel is mounted on the side of the control plate through the connecting posts. The surface of the connecting posts is cylindrical, and the charging cable is led out from the upper side of the connecting post 31. The connecting post serves to limit the charging cable, and the cylindrical surface of the connecting post makes the charging cable smoother and less prone to scratches during the winding process.
