[0049] This invention relates to a vehicle-mounted USB charging module with a retractable charging cable. During use: Firstly, users can directly insert their own prepared charging cable. Secondly, if no charging cable is available or the charging port is incompatible, the user can open the cover 11. After opening the cover 11, button 70 will pop out, allowing the user to freely extend the USB charging cable 400 to a suitable length. The corresponding charging adapter 100 can be removed from the cover 11. Closing the cover 11 will press button 70 in, locking the ratchet 410. At this point, the charging cable will not be retracted into the module, allowing for safe use.

[0050] After use, the user opens the cover 11, puts the charging adapter 100 back in, slowly releases their hand, the button 70 pops out, the ratchet 410 is released, and under the action of the coil spring 430, the USB charging cable 400 is retracted, completing the storage.

[0051] The operation of the in-vehicle USB charging module with a retractable charging cable of the present invention is as follows: When the cover 11 is opened, the button 70 pops out under the action of the spring 71, and the ratchet 410 unlocks. Pulling the USB charging cable 400 will drive the coil spring 430, ratchet 410, and energized ring 50 to rotate. The six metal protrusions inside the energized ring 50 make contact with the six metal rings inside the energized shaft 60. The energized ring 50 rotates around the energized shaft 60, and the module is powered while rotating.

[0052] Pull the USB charging cable 400 freely to the desired length, close the cover 11, press down the button 70, lock the ratchet 410, and the USB charging cable 400 will not retract under the action of the coil spring 430. After use, open the cover 11, the spring 71 will cause the button 70 to pop out, the ratchet 410 will unlock, and the USB charging cable 400 will retract under the action of the coil spring 430, completing the storage. The charging adapter 100 equipped on the back of the cover 11 includes one Android charging port and one Apple charging port, which can be selected according to the user.

[0053] Therefore, the present invention solves the problem that existing vehicle USB modules are not equipped with charging cables and are inconvenient to use and store by setting up PCB board 30, connecting wire 40, power-conducting shaft 60, power-conducting ring 50, ratchet 410, coil spring 430, USB charging cable 400, spring 71, button 70, and charging adapter 100.
