[0038] Please also refer to Figures 1 to 7 This utility model provides a preferred embodiment of a charging device.

[0039] In some embodiments, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a charging device, which includes a housing 1, a plug 2, a third circuit board 3, and a retractable charging cable device. The retractable charging cable device is disposed inside the housing 1; the plug 2 is connected to the third circuit board 3; the third circuit board 3 is connected to the second circuit board 10, and the third circuit board 3 is used to convert mains power into the voltage required by the retractable charging cable device.

[0040] Specifically, the plug 2 is a two-pin plug that can be connected to AC power and input the AC power to the third circuit board 3. The third circuit board 3 can rectify the input AC power and further step down the voltage to output the voltage required by the retractable charging cable device. The retractable charging cable device can charge electrical devices such as mobile phones and tablets.

[0041] In some embodiments, as Figures 3 to 6As shown, the telescopic charging cable device includes: a lower cover 4, an upper cover 5, a turntable 6, a coil spring 7, a limiting member 8, a data cable 13, a first circuit board 9, and a second circuit board 10. The lower cover 4 is provided with a rotating shaft 41, and the upper cover 5 is provided with a receiving cavity 51 adapted to the rotating shaft 41. The rotating shaft 41 is located inside the receiving cavity 51, and the lower cover 4 is connected to the upper cover 5 through the rotating shaft 41. The turntable 6 is disposed on the lower cover 4 and rotatably connected to the rotating shaft 41. One end of the coil spring 7 is disposed on the turntable 6, and the other end of the coil spring 7 is sleeved on the rotating shaft 41. The limiting member 8 is disposed on the upper cover 5 and is used to cooperate with the turntable 6 to lock the turntable 6. The data cable 13 is disposed on the lower cover 4 and connected to the turntable 6. The first circuit board 9 is disposed on the turntable 6 and rotatably connected to the rotating shaft 41, and the first circuit board 9 is electrically connected to the data cable 13. The second circuit board 10 is disposed on the upper cover 5 and connected to the second circuit board 10.

[0042] Specifically, by pulling the data cable 13, the turntable 6 can be rotated. The coil spring 7 has a power storage effect, allowing the data cable 13 to return to its initial position. The limiting member 8 can cooperate with the turntable 6. When the data cable 13 is pulled and the turntable 6 rotates to a certain position, the limiting member 8 engages with the turntable 6, stopping the turntable 6 from rotating. When the data cable 13 is pulled again, the limiting member 8 disengages from the turntable 6, and the data cable 13 can return to its initial position, thus completing the automatic retraction and extension of the data cable 13. The data cable 13 is connected to the first circuit board 9, the first circuit board 9 is connected to the second circuit board 10, and the second circuit board 10 is connected to the third circuit board 3. Thus, the mains power can be converted into the voltage required by the charging device via the third circuit board 3, and then transmitted to the first circuit board 9 via the second circuit board 10. From the first circuit board 9, the data cable 13 transmits the power to the device.

[0043] After the coil spring 7 is sleeved on the rotating shaft 41, the upper cover 5 is then connected to the lower cover 4. In this way, the suspended end of the rotating shaft 41 is housed in the accommodating cavity 51 of the upper cover 5, making the rotating shaft 41 less prone to bending and deformation when subjected to force, thus preventing breakage and improving the service life of the telescopic charging cable device.

[0044] In some embodiments, as Figures 4 to 6 As shown, the rotating shaft 41 is provided with an internal threaded hole, and the upper cover 5 is connected to the rotating shaft 41 by screws.

[0045] Specifically, the top of the rotating shaft 41 has an internal threaded hole, and the upper cover 5, the second circuit board 10, and the third circuit board 3 are all provided with through holes. The connection between the upper cover 5 and the lower cover 4 can be achieved by connecting the upper cover 5 and the rotating shaft 41 with screws.

[0046] Furthermore, such as Figure 5 and Figure 6 As shown, the upper cover 5 is provided with a plurality of buckles 52 at intervals around its periphery, and the lower cover 4 is provided with a slot 42 at the position corresponding to the buckles 52. The upper cover 5 is engaged with the lower cover 4 through the buckles 52.

[0047] Specifically, the upper cover 5 and the lower cover 4 are approximately octagonal in shape. The buckles 52 are spaced apart on the edge of the upper cover 5. The slots 42 on the lower cover 4 correspond to the positions of the buckles 52 on the upper cover 5. The upper cover 5 is fastened to the lower cover 4 by the buckles 52 to ensure the stability between the upper cover 5 and the lower cover 4.

[0048] In some embodiments, as Figure 7 As shown, the turntable 6 is provided with a first mounting part 63, a second mounting part 64 and a third mounting part 65; the data cable 13 is arranged around the first mounting part 63; the coil spring 7 is located inside the first mounting part 63, and one end of the coil spring 7 is sleeved on the second mounting part 64; the data cable 13 is clamped between the third mounting part 65 and the first mounting part 63.

[0049] Specifically, the first mounting portion 63 is a ring structure, and the data cable 13 is wound around the periphery of the first mounting portion 63, while the coil spring 7 is housed within the first mounting portion 63. The first mounting portion 63 has a notch, and the second mounting portion 64 is disposed within the notch of the first mounting portion 63, with one end of the coil spring 7 sleeved within the second mounting portion 64. The third mounting portion 65 is located on one side of the periphery of the first mounting portion 63, clamping the data cable 13 between the first mounting portion 63 and the third mounting portion 65 to fix the end of the data cable 13.

[0050] In some embodiments, as Figure 3 and Figure 5 As shown, one end of the limiting member 8 is provided with a first through hole 81, and the upper cover 5 is provided with a first cylinder 53. The limiting member 8 is rotatably connected to the first cylinder 53. The other end of the limiting member 8 is provided with a second cylinder 82. The turntable 6 is provided with a sliding groove 61 and an opening 62 provided on one side of the sliding groove 61. The second cylinder 82 is slidably connected to the sliding groove 61.

[0051] Specifically, the limiting member 8 is approximately wedge-shaped. One end of the limiting member 8 is rotatably connected to the upper cover 5 via the first cylinder 53, and the other end is slidably connected to the groove 61 on the turntable 6 via the second cylinder 82. When the turntable 6 rotates under the drive of the data cable 13, the limiting member 8 can slide along the groove 61. When the limiting member 8 slides into the opening 62, the limiting member 8 has a locking effect on the turntable 6, and the turntable 6 stops rotating when no further force is applied. When the turntable 6 continues to rotate under the pull of the data cable 13, the limiting member 8 disengages from the opening 62. When the limiting member 8 reaches the opening 62 again, the turntable 6 stops rotating. In one implementation, the groove 61 is provided with two openings 62.

[0052] In some embodiments, as Figure 3 and Figure 5 As shown, the first circuit board 9 is provided with a terminal block 91, and the second circuit board 10 is provided with an annular terminal 101 that contacts the terminal block 91.

[0053] Specifically, the first circuit board 9 is disposed on the turntable 6 and rotates synchronously with the turntable 6. The terminals of the terminal block 91 are in contact with the annular terminal 101 of the second circuit board 10. In this way, when the first circuit board 9 rotates, the terminal block 91 and the annular terminal 101 can be kept in a connected state.

[0054] In some embodiments, two terminal blocks 91 are provided and spaced apart on the first circuit board 9, which can ensure the stability of the electrical connection between the first circuit board 9 and the second circuit board 10.

[0055] In some embodiments, one end of the data line 13 is connected to the terminal block 91, and the other end of the data line 13 is a TYPE-C male connector.

[0056] In some embodiments, as Figure 1 As shown, the housing 1 is provided with a second through hole 11 and a wire-holding groove 12; the data cable 13 passes through the second through hole 11; the wire-holding groove 12 is located on one side of the second through hole 11 and is used to fix the data cable 13.

[0057] Specifically, the data cable 13 extends out of the second through hole 11, wherein the diameter of the second through hole 11 is smaller than the diameter of the TYPE-C male connector of the data cable 13, so that the TYPE-C male connector will not enter the housing 1. In addition, in order to better retract the data cable 13, a cable retaining groove 12 is also provided in the housing 1, into which the TYPE-C male connector can be inserted to secure the data cable 13.

[0058] In summary, the retractable charging cable device and charging equipment provided by this utility model have the following beneficial effects:

[0059] By connecting the rotating shaft with the coil spring mounted on the lower cover to the accommodating cavity of the upper cover, the suspended end of the rotating shaft is confined within the accommodating cavity of the upper cover. In this way, after the lower cover and the upper cover are installed, the rotating shaft of the lower cover is no longer suspended, making it less prone to deformation when subjected to the tension of the coil spring. This can prevent the rotating shaft from breaking after long-term use, thereby improving the service life of the cable winder.

[0060] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
