[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example

[0033] like Figure 1-6 As shown, an embodiment of the present invention provides an integrated charging cable structure for a charger, comprising a charger body 1;

[0034] The charging cable 2 is integrated into the charger body 1, and the charging cable 2 assembly is configured to reversibly switch between a charging state and a lanyard state.

[0035] The physical integration of the charging cable 2 with the charger body 1 avoids the risk of cable loss. The integrated structural design makes the charging cable 2 an inseparable part of the charger body 1, making it more convenient to use when out and about and preventing the situation of forgetting to bring the charging cable 2.

[0036] like Figure 1-3 As shown, in some embodiments, one end of the charging cable 2 extends into the interior of the charger body 1 and is electrically connected to the circuit board 11 inside the charger body 1, while the other end is provided with a charging connector 21.

[0037] The charging cable 2 is directly soldered onto the circuit board 11 to form a permanent conductive path, ensuring the reliability of the electrical connection and reducing energy loss caused by contact resistance.

[0038] like Figure 4 As shown, in some embodiments, the top of the charger body 1 is provided with a plurality of battery slots 12, and the top of the circuit board 11 is integrated with a plurality of sets of metal sheets 13 that are the same number as the battery slots 12 and correspond one-to-one. Each set of metal sheets 13 includes two metal springs located at both ends of the battery slots 12 respectively, and the outer surface of the metal springs is silver-plated.

[0039] Each set of metal sheets 13 corresponds independently to the battery slot 12 to avoid crosstalk and accidental contact. The symmetrical layout of the metal springs forms a bidirectional clamping force to ensure stable contact between the battery and the contacts. The silver plating reduces the contact resistance of the metal springs, significantly improving charging efficiency. The high conductivity of the silver plating reduces heat generation at the contact points and supports higher current transmission.

[0040] like Figure 3 As shown, in some embodiments, a storage slot 3 is also included, which is disposed on one side of the charger body 1.

[0041] The charging cable 2 is stored in a directional way using the side storage slot 3. The storage slot 3 provides a neat storage space for the cable and improves the portability of the product.

[0042] like Figure 2 As shown, in some embodiments, the length of the storage slot 3 is greater than the length of the charging connector 21, and one end of the inner wall of the storage slot 3 is provided with a guide arc slope 31, and the other end is provided with a cable passage 32.

[0043] With the guide ramp 31 in place, when the user needs to remove the charging plug, they can push the charging connector 21 with their thumb, causing one end of the charging connector 21 to disengage from the retaining edge 33, and the other end to move toward the guide ramp 31. This allows one end of the charging connector 21 to automatically tilt up and slide out of the storage slot 3 along the guide ramp 31, so that it can be used for charging. The operation is simple and quick, meeting the user's needs.

[0044] like Figure 2 As shown, in some embodiments, a baffle 33 is provided on the top and bottom of one side of the cable port 32. In some embodiments, the charging connector 21 is movably disposed inside the storage groove 3, and one end of it is movably engaged with the baffle 33.

[0045] When the user pulls the charging cable 2 while it is hanging on the lanyard, the charging cable 2 causes one end of the charging connector 21 to be more tightly engaged with the edge 33, achieving a tightening effect as it is pulled, which further ensures the stability when hanging on the lanyard.

[0046] like Figure 2 As shown, in some embodiments, the charging state is the unfolded state when the charging connector 21 is completely detached from the storage slot 3, and the hanging rope state is the stored state when the charging connector 21 enters the storage slot 3 and is snapped into the guard edge 33.

[0047] The cable port 32 is wider than the charging cable 2, allowing the charging cable 2 to freely enter and exit the cable port 32. This design makes it easier to store the charging connector 21.

[0048] like Figure 4-5As shown, in some embodiments, a cable clip 4 is also included. The cable clip 4 is fixedly disposed inside the charger body 1. In some embodiments, a cable tail 22 is provided on one end of the charging cable 2 that enters the charger body 1 and is connected to the inside of the cable clip 4. A slot 23 is provided on the cable tail 22. A limiting rib 41 is provided inside the cable clip 4 that is engaged with the slot 23.

[0049] The cooperation between the cable clip 4 and the cable tail 22 ensures that when the charging cable 2 is pulled, the charging cable 2 will not be pulled directly to the solder joint with the circuit board 11. Instead, the charging cable 2 will pull the cable tail 22 directly, which is held in place by the cable clip 4, further ensuring the stability of the charging cable 2.

[0050] In summary, the risk of cable loss is completely eliminated through physical integration design. The one-piece molding design makes the charging cable 2 an inseparable part of the charger body 1. The charging cable 2 achieves a self-locking effect by engaging with the edge 33 when hanging, significantly enhancing the contact pressure under external force and ensuring suspension stability. The storage slot 3 and the guide arc slope 31 work together to achieve quick one-handed switching, making operation far more convenient than traditional designs. The stress dispersion system formed by the cable clip 4 and the limiting rib 41 effectively protects the welding points, greatly improving the tensile strength of the cable. The cable passage 32 design of the side storage slot 3 ensures that the charging cable 2 can slide freely while maintaining its neatness. The overall structure takes into account both portability and reliability.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
