On January 29, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Guangdong Hobart Technology Co., Ltd. had obtained a patent entitled "a portable charger", with the authorization announcement number of CN220401445U and the application date of May 2023.
The patent abstract shows that the present utility model provides a portable charger, comprising a charger. The side surface of the charger is fixedly connected to a limit block, and the surface of the limit block is movably connected to a wire collection box. One side of the wire collection box has a limited slot on its surface, and the inner side of the wire collection box is equipped with a winding mechanism. One side of the charger is fixedly connected to a charging wire. This portable charger is equipped with a winding mechanism. When in use, the charging cable can be pulled to drive the connecting plate to rotate. The connecting plate rotates to drive the panel to rotate, and the panel drives the ratchet to rotate. The rotating ratchet will not be stuck by the ratchet block. At this time, the flat scroll spring shrinks in the scroll spring slot. When the wire needs to be wound, press the button to compress the spring. One end of the telescopic rod moves horizontally to prevent the ratchet block from engaging with the ratchet. At the same time, the flat scroll spring rebounds, which will drive the charging wire to rotate in the opposite direction around the connecting plate and recover the charging wire. This completes the winding of the charger wire.
