It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-4 The image shown is an embodiment provided by this utility model.

[0030] This utility model provides an automatic winding device, including: a wire box 10, a winding reel 20, a motor 30, and a power supply 40. The winding reel 20 is rotatably disposed inside the wire box 10. The motor 30 is electrically connected to the power supply 40 and is driven by the winding reel 20. The power supply 40 supplies power to the motor 30, and the rotation of the motor 30 drives the winding reel 20 to rotate. Specifically, the winding reel 20 includes a winding cylinder 21 coaxially disposed in the middle of the winding reel 20. The winding cylinder 21 is a hollow cylinder. A connecting plate 22 is disposed near the upper end of the winding cylinder 21. The connecting plate 22 is fixedly connected to the inner wall of the winding cylinder 21. The motor 30 is coaxially disposed inside the winding cylinder 21. At the same time, the outer shell of the motor 30 does not contact the inner wall of the winding cylinder 21 to avoid friction between the winding cylinder 21 and the outer shell of the motor 30 when the winding cylinder 21 rotates, which would affect the rotation speed. The lower end of the motor 30 is fixedly connected to the wire box 10. The output shaft of the motor 30 is supported and connected to the connecting plate 22, so that the winding reel 20 is suspended inside the wire box 10. In order to make the output shaft of the motor 30 and the connecting plate 22 stably connected, a flange 31 can be used as a connecting part for fixation. When the output shaft of the motor 30 rotates, the winding cylinder 21 can carry the entire winding cylinder 20. The winding reel 20 rotates together; a wire-clamping notch 23 is provided on the upper side wall of the winding drum 21; a limit cover 11 is provided on the inner top of the wire box 10, which rotates coaxially with the winding drum 21; the bottom wall of the limit cover 11 can abut against the opening end of the wire-clamping notch 23; the size of the wire-clamping notch 23 can be set according to various specifications for different users, such as according to the different wire thicknesses of electrical appliances, mobile phone charging cables, and headphone cables, so that the size of the wire-clamping notch 23 is just the same as or slightly smaller than the wire thickness; with the squeezing of the limit cover 11, the wire in the middle is pressed tightly into the wire-clamping notch 23, which can firmly clamp the wire end and prevent it from falling off; when the winding column rotates, the limit cover 11 will also rotate with it, so that the limit cover 11, the wire end and the wire-clamping notch 23 maintain a constant relative position, forming a stable fixation for the wire end. After adopting the above-mentioned automatic winding device, by cooperating with the wire-clamping notch 23 set at the upper end of the winding drum 21 and the limiting cover 11 set at the top of the wire box 10, the wire end only needs to be clamped in the wire-clamping notch 23 and pressed down by the limiting cover 11, which can quickly and firmly fix the wire end, making the operation convenient and the wire end less likely to come loose.

[0031] Furthermore, a limiting ring 111 is provided in the middle of the bottom wall of the limiting cover 11. The outer side wall of the limiting ring 111 is sleeved with the inner side wall of the upper end of the winding drum 21. This means that the limiting ring 111 can be inserted into the winding drum 21 from above. When the wire end is caught in the wire-catching notch 23, the wire body can be further pressed down and tightened to prevent the wire end from coming loose.

[0032] Furthermore, there are two wire-clamping notches 23, which are positioned opposite each other on both sides of the axis of the winding drum 21. By simultaneously clamping the wire end into the two wire-clamping notches 23, the wire end can be clamped more tightly and is less likely to come loose.

[0033] Specifically, the cable box 10 includes a circular upper shell 101 and a lower shell 102. One side of the upper shell 101 is hinged to one side of the lower shell 102, so that the upper shell 101 and the lower shell 102 can be flipped to cover each other. When it is necessary to wind the cable, simply flip the upper shell 101 open to quickly lock the cable end in the cable locking notch 23, making the operation of fixing the cable end more convenient.

[0034] Furthermore, a buckle 12 is provided on the side of the upper shell 101 away from its hinge axis, and a locking part 13 is provided on the side of the lower shell 102 away from its hinge axis. The buckle 12 can engage with the locking part 13, so that the upper shell 101 and the lower shell 102 will not be easily knocked apart during the winding process of the winding machine, ensuring that the limiting cover 11 can be stably pressed on the upper end of the winding drum 21, thereby locking the wire end.

[0035] Specifically, a fixed plate 14 is provided inside the lower shell 102, and the motor 30 is mounted on the fixed plate 14. The fixed plate 14 is mounted in the middle of the lower shell 102, so that there is space between the bottom of the lower shell 102 and the bottom of the fixed plate 14. The power supply 40 is located below the fixed plate 14, which facilitates connection with the motor 30.

[0036] Furthermore, the latching part 13 is movably disposed on the side of the lower shell 102. A baffle 141 is disposed on the side of the fixing plate 14 at a position corresponding to the latching part 13. A return spring 142 is connected between the baffle 141 and the latching part 13. The outer end of the latching part 13 protrudes from the surface of the wire box 10. Pressing the latching part 13 inward can disengage the buckle 12 from it. At the same time, the return spring 142 is squeezed. When the latching part 13 is released, the spring force of the return spring 142 is released, which can reset the latching part 13. At this time, the buckle 12 can still be latched and fixed with the latching part 13.

[0037] Furthermore, two cable routing openings 15 are provided on the circumferential sidewall of the cable box 10. The two cable routing openings 15 are symmetrically arranged on opposite sides of the cable box 10, which facilitates the other end of the cable to extend out. At the same time, the middle part of the cable can also be fixed in the two cable clamping notches 23. The two ends of the cable extend out from the two cable routing openings 15 respectively. In this way, when the winding reel 20 rotates, the cables on both sides will be wound onto the winding drum 21 at the same time, which can speed up the winding speed.

[0038] Specifically, the cable box 10 is equipped with a circuit board 50, which is electrically connected to the power supply 40 and the motor 30 respectively. The circuit board 50 is used to control the rotation of the motor 30. The bottom of the cable box 10 is equipped with a charging interface 51 and a switch button 52, which are electrically connected to the circuit board respectively, so as to facilitate the opening and closing of the cable reel from the outside. At the same time, it can also replenish the power supply 40 and extend the working time of the cable reel.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this 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 specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
