[0029] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0030] like Figure 1-7As shown, this utility model discloses a retractable charging cable with a cigarette lighter, including an expansion dock body 10, a cigarette lighter 20, a power plug 30, a charging plug 40, and a retractable charging cable assembly. The cigarette lighter and the expansion dock body 10 are separately configured. The retractable charging cable assembly includes a charging cable 50 that can freely extend and retract into the expansion dock body 10. The free end of the charging cable 50 is connected to the charging plug 40. The charging plug 40 is electrically connected to the power plug 30 through the charging cable 50. The cigarette lighter 20 is provided with a cigarette lighter switch 21 and a power supply interface 22 for use with the charging plug 40. Ignition is powered through the power supply interface 2. Specifically, the cigarette lighter 20 is provided with a heating circuit board, and the power supply interface 22 is electrically connected to the heating circuit board. The expansion dock body 10 is provided with a charging plug storage slot 11 for storing the charging plug 40 and a cigarette lighter storage slot 12 for storing the cigarette lighter 20. By setting a power supply interface 22 on the cigarette lighter 20 that matches the charging plug 40, when a cigarette needs to be lit, the cigarette lighter 20 can be removed from the expansion dock and used with the charging plug 40. When charging is needed, the charging plug 40 can be used directly. The charging plug 40 can charge other devices and supply power to the cigarette lighter 20. At the same time, the retractable charging cable group makes it convenient for other devices to be charged within a suitable range and for the cigarette lighter to be lit within a comfortable range.

[0031] With the widespread adoption of Type-C connectors, for ease of use, the charging plug 40 and the power supply interface 22 are both Type-C. The cigarette lighter can be used not only in vehicles but also detached from the docking station for independent use at home, in the office, or outdoors via a Type-C data cable. In practical applications, the charging plug 40 is not limited to a Type-C plug, and the power supply interface 22 is not limited to a Type-C interface; the charging plug 40 can also be a Micro or Lightning plug, and the power supply interface can be the corresponding Micro or Lightning interface.

[0032] In this embodiment, the cigarette lighter 20 is a miniature cigarette lighter, which is easy to carry. Miniature cigarette lighter technology is a mature existing technology, and can be referred to the patent with publication number CN218820516U. Therefore, the technical principle of the miniature cigarette lighter will not be described in detail.

[0033] For easy carrying, the lower end of the cigarette lighter has a lanyard hole 23. When used alone, a lanyard can be tied through the lanyard hole 23 for hanging or attaching to a keychain.

[0034] In this embodiment, the power plug is a vehicle power plug. In practical applications, the power plug is not limited to vehicle power plugs, but can also be a USB plug, which can be used both inside and outside the vehicle, making this utility model have more application scenarios.

[0035] In order to charge multiple electronic devices, the main body 10 of the expansion dock is also provided with a charging interface 13, which is electrically connected to the power plug 30.

[0036] In this embodiment, the charging interface 13 includes a USB interface and a Type-C interface.

[0037] For ease of use, the charging plug 40, the charging plug storage slot 11, and the cigarette lighter storage slot 12 are all located at the end of the docking station body 10 away from the power plug 30.

[0038] The main body 10 of the expansion dock is equipped with a locking structure to accommodate and lock the telescopic charging cable assembly, and to keep the telescopic charging cable assembly stable when the charging cable 50 is stretched or retracted.

[0039] The retractable charging cable assembly includes a cable box 14 for storing the charging cable 50 and a cable retraction structure (not shown) for retracting the charging cable 50 back into the cable box. The cable retraction structure is located inside the cable box. In this embodiment, the cable retraction structure is a spring-loaded mechanism. Spring-loaded cable retraction technology is a mature existing technology, and can be found in patent number ZL2024 20745791.X. Therefore, the technical principle of the cable retraction structure will not be described in detail. Similarly, the braking principle of the spring-loaded mechanism can also be found in patent number ZL202420745791.X.

[0040] In order to adjust the angle of the expansion dock body 10, the expansion dock body 10 is rotatably connected to the power plug 30.

[0041] In this embodiment, for convenient placement of the cigarette lighter, the cigarette lighter body 20 is cylindrical, and the cigarette lighter storage slot 12 corresponds to the cigarette lighter. In practical applications, the cigarette lighter body 20 can be square prism, triangular prism, etc., but a cylindrical cigarette lighter is only a preferred choice in this embodiment.

[0042] The cable box 14 has a non-circular outer shell structure. In this embodiment, it is a square structure with rounded edges. The corresponding expansion dock body 10 includes a left shell and a right shell. Inside these two shells, there are two opposing constraint baffles 103. The enclosure space formed by the constraint baffles 103 matches the shape of the cable box 14, so that the cable box 14 remains stable when the telescopic charging cable 50 is pulled or when the internal spring generates force, thereby ensuring that the telescopic charging cable 50 can be accurately and reliably stretched or contracted.

[0043] To further ensure accurate installation and stable stress distribution of the junction box 14, a guide protrusion 104 is provided on the inner edge of the constraint baffle 103, and a corresponding guide groove 141 is provided on the housing of the junction box 14. The aforementioned effect is achieved through the cooperation of these two elements. In practical applications, the junction box 14 can also be a circular outer shell structure; a square structure with rounded edges is only a preferred choice in this embodiment.

[0044] This design achieves the detachable use of the cigarette lighter body 20 and the docking station body 10. The cigarette lighter body 20 can be removed separately and used with the charging plug 40 of the charging cable. Furthermore, the use of a spring-loaded retractable charging cable allows the charging cable 50 to be completely stored inside the docking station body 10, ensuring a clean and simple vehicle environment and preventing unnecessary tangling. Extending the cable out of the docking station body 10 does not exert any tension on the charging equipment, making it more convenient to use.

[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
