[0030] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a layered single / double pull charging cable, used to power the device with the matching base 9, such as... Figures 1-6 As shown, it includes:

[0033] The lower shell 1 and the upper shell 2 are interlocked. The lower shell 1 and the upper shell 2 are respectively provided with a first connecting rod 11 and a second connecting rod 21. The first connecting rod 11 and the second connecting rod 21 can be spliced ​​together along their length to form a support rod. The first connecting rod 11 and the second connecting rod 21 are both provided with grooves 22.

[0034] Regarding the two symmetrically arranged rotating seats 3 of the support rod, a circuit board 5 is provided on the side adjacent to the two rotating seats 3, and a spring 4 is provided on the side opposite to each other. The first end of the spring 4 is engaged with the groove 22, and the second end is connected to the rotating seat 3.

[0035] At least one connector 7 is disposed on one of the circuit boards 5 and is connected to the other circuit board 5 by a sliding contact to achieve rotational conductivity;

[0036] The data cable 6 is located on the rotating base 3. The data cable 6 extends into the interior of the rotating base 3 through the opening 31 of the rotating base 3 and is electrically connected to the circuit board 5.

[0037] It should be noted that the base 9 has a transmitting coil inside, and the lower housing 1 and the upper housing 2 have receiving coils inside. The device is powered by wireless charging via the data cable 6. The receiving coil is connected to the circuit board 5 through a conductive slip ring, or through other sliding contact methods to achieve circuit conduction.

[0038] It should be noted that during the process of extending the data cable 6, the rotating seat 3 and the circuit board 5 rotate synchronously, and the spring 4 accumulates elastic potential energy. When retracting the data cable 6, the spring 4 uses its own elastic force to drive the data cable 6 to reset. During the rotation, the connector 7 can slide relative to the slidingly fitted circuit board 5, so that the two circuit boards 5 can rotate independently.

[0039] The two rotating seats 3 arranged in layers and the two circuit boards 5 provided with them provide power to the two data cables 6 respectively. At the same time, the two rotating seats 3 can rotate independently, so that the two data cables 6 can be pulled out and retracted independently, thereby selectively charging one or two devices and improving the functionality of the product.

[0040] like Figure 2 and Figure 4 As shown, the first connecting rod 11 has a positioning rod at its tail, and the second connecting rod 21 has a positioning groove corresponding to the fixed rod, with the positioning rod fitting into the positioning groove. It should be noted that when the positioning rod is engaged in the positioning groove, the grooves 22 of the first connecting rod 11 and the second connecting rod 21 are connected.

[0041] like Figure 2 and Figure 3 As shown, the width of the groove 22 is greater than or equal to the thickness of the spring 4. When the lower housing 1 and the upper housing 2 are engaged, the spring 4 abuts against the bottom wall of the groove 22. It should be noted that when the rotating seat 3 rotates, it can drive the spring 4 to rotate synchronously. At this time, one end of the spring 4 is engaged inside the groove 22, which can realize the accumulation of elastic potential energy of the spring 4.

[0042] like Figures 2-4As shown, the rotating seat 3 has a groove corresponding to the support rod. The rotating seat 3 is sleeved on the outside of the support rod through the groove, and the rotating seat 3 can rotate around the support rod. It should be noted that the rotating seat 3 can rotate outside the support rod. The position of the rotating seat 3 is limited by the spring 4 that is engaged inside the groove 22. At the same time, the elastic connector 7 can support the two rotating seats 3 and limit their position.

[0043] like Figures 2-5 As shown, the circuit board 5 has a slot, which allows it to be fitted onto the outside of the support rod and engaged with the locking block of the rotating base 3. When the rotating base 3 rotates, it drives the circuit board 5 to rotate synchronously. It should be noted that one end of the data cable 6 is a charging head, while the other end is positioned by the rotating base 3 and electrically connected to the circuit board 5. This allows the circuit board 5 to rotate along with the rotating base 3 when the data cable 6 is pulled, thus maintaining a stable electrical connection.

[0044] like Figure 3 and Figure 6 As shown, connector 7 includes mounting base 71 and conductive spring 72. Mounting base 71 is used to mount multiple conductive springs 72. The two ends of conductive spring 72 are respectively connected to two circuit boards 5 to form a conductive path.

[0045] like Figure 6 As shown, the conductive spring 72 has an elastic bend, which is elastic and used to reduce friction. It should be noted that the conductive spring 72 is used to connect two circuit boards 5. When one of the two circuit boards 5 rotates independently, the elastic bend of the conductive spring 72 will slide relative to the circuit board 5 and abut against the circuit board 5 by means of elastic force to maintain circuit continuity.

[0046] like Figure 4 As shown, both the lower housing 1 and the upper housing 2 are equipped with magnets 8 inside, which are used to form a magnetic attraction with the magnets inside the base 9.

[0047] like Figure 1 and Figure 3 As shown, both the lower housing 1 and the upper housing 2 have an arc-shaped guide structure on the side that contacts the base 9. When the lower housing 1 or the upper housing 2 is placed on the base 9, the guide structure is used to form a circumferential limit.

[0048] like Figure 1 and Figure 4 As shown, the lower housing 1 and the upper housing 2 are provided with slots for the data cable 6 to pass through, and the data cable 6 extends through the slots to the outside of the lower housing 1 and the upper housing 2.

[0049] Working principle: The two rotating seats 3, which are arranged in layers, and the two circuit boards 5 are provided with power to the two data cables 6 respectively. At the same time, the two rotating seats 3 can rotate independently, so that the two data cables 6 can be pulled out and retracted independently, thereby selectively charging one or two devices, improving the functionality of the product.

[0050] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
