[0010] A rotating disk is mounted on the module support and can rotate relative to the module support;

[0011] A third transmission gear is connected to the rotating disk, and the third transmission gear drives the rotating disk to rotate.

[0012] When the first transmission gear rotates in the forward direction, the first transmission gear drives the second rotating shaft to move along the meshing adjustment groove toward the direction of the third transmission gear, so that the second transmission gear meshes with the third transmission gear, drives the third transmission gear to rotate, and thus drives the rotating disk to rotate;

[0013] When the first transmission gear rotates in the opposite direction, the first transmission gear drives the second shaft to move away from the third transmission gear along the meshing adjustment groove, so that the second transmission gear and the third transmission gear disengage.

[0014] The winding module also includes:

[0015] The third rotating shaft is mounted on the module bracket and connected to the third transmission gear;

[0016] A fourth rotating shaft is mounted on the module support, and the rotating disk is fitted onto the fourth rotating shaft;

[0017] The fourth transmission gear is sleeved on the fourth rotating shaft and fixedly connected to the rotating disk. The fourth transmission gear is located below the rotating disk and meshes with the third transmission gear.

[0018] The side of the winding reel is provided with drive teeth;

[0019] The first transmission gear includes a lower gear and an upper gear arranged in a vertical direction; the lower gear is fixedly connected to the upper gear;

[0020] The drive gear meshes with the lower gear, and the upper gear meshes with the second transmission gear.

[0026] The module support includes:

[0027] The upper cover covers the upper end of the middle cover; the first pivot is supported between the base and the middle cover;

[0028] A receiving space is formed between the upper cover and the middle cover, and the second rotating shaft, the third rotating shaft, the second transmission gear and the third transmission gear are disposed in the receiving space; the upper and lower ends of the second rotating shaft and the third rotating shaft are respectively supported on the middle cover and the upper cover;

[0029] The meshing adjustment groove includes a lower meshing adjustment groove on the upper surface of the middle cover and an upper meshing adjustment groove on the lower surface of the upper cover. The lower meshing adjustment groove and the upper meshing adjustment groove are symmetrically arranged facing each other.

The ratchet plate is sleeved on the ratchet shaft through the shaft hole and can rotate relative to the ratchet shaft. The stop shaft is inserted into the rotating groove. When the reel rotates relative to the base, the rotating groove rotates around the stop shaft relative to the base, and when the stop shaft is blocked in the blocking recess, it can prevent the reel from rotating in the forward direction.

[0035] The rotating disk is equipped with an effect diagram or a light ring.

[0036] This utility model also provides an electronic device with a winding module, including a data cable with a USB interface. The electronic device with the winding module further includes the winding module described above, and the data cable is wound on the winding spool.

[0037] This utility model also provides a power bank, including a data cable with a USB interface, and the power bank also includes the above-mentioned winding module, with the data cable wound on the winding spool.

[0038] This invention features a cable reel mounted on a module bracket, along with a first transmission gear, an adjustment groove, a second transmission gear, a rotating disk, and a third transmission gear. When the first transmission gear rotates forward, it drives a second rotating shaft to move along the adjustment groove towards the third transmission gear, engaging it and driving the third transmission gear to rotate, thereby driving the rotating disk to rotate. When the first transmission gear rotates in the reverse direction, it drives the second rotating shaft to move along the adjustment groove away from the third transmission gear, disengaging it from the third transmission gear.

[0048] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0049] Please see also Figures 1 to 8 This utility model winding module includes a module bracket 1, a winding reel 2, a first rotating shaft 31, a first transmission gear 32, a meshing adjustment groove 4, a second rotating shaft 41, a second transmission gear 42, a rotating disk 5, a third rotating gear 61, a third rotating shaft 62, a fourth rotating shaft 71, and a fourth transmission gear 72. Wherein:

[0050] The module bracket 1 primarily serves a supporting function. The module bracket 1 is typically installed inside the housing of the electronic device, requiring only the rotating disk or its upper surface to protrude.

[0051] The cable reel 2 is mounted on the module bracket and can rotate relative to the module bracket. The side of the cable reel 2 is provided with a cable groove 21, and the data cable 22 is wound in the cable groove 21. The end of the data cable 22 is provided with a USB interface 221, so that it can be connected to other electronic devices through the USB interface to realize charging or data transmission.

[0052] The first rotating shaft 31 is mounted on the module support. The first rotating shaft is mainly used for positioning and supporting the first transmission gear.

[0053] The first transmission gear 32 is fitted onto the first rotating shaft, and the first transmission gear is connected to the winding reel and rotates under the drive of the winding reel.

[0054] The meshing adjustment groove 4 is provided on the module support. The meshing adjustment groove is mainly used to allow the second rotating shaft to move, so that the second transmission gear can mesh or disengage with the third transmission gear, thereby achieving unidirectional drive of the rotating disk. The specific position and length of the meshing adjustment groove can be determined according to the position and diameter of the first, second, and third transmission gears. When the first transmission gear rotates in the forward direction, it can drive the second and third transmission gears to mesh, thereby transmitting the rotation of the winding reel to the third transmission gear and the rotating disk. When the first transmission gear rotates in the reverse direction, it can drive the second and third transmission gears to disengage, thereby blocking the transmission of the winding reel's rotation to the third transmission gear.

[0055] The second rotating shaft 41 is inserted into the meshing adjustment groove and can move within the groove. The second rotating shaft supports and positions the second transmission gear. Under the forward or reverse drive of the first transmission gear, the second rotating shaft can move between the two ends of the meshing adjustment groove.

[0056] The second transmission gear 42 is fitted onto the second rotating shaft, and the second transmission gear meshes with the first transmission gear and rotates under the drive of the first transmission gear.

[0057] The rotating disk 5 is mounted on the module support and can rotate relative to the module support. The rotating disk is equipped with an effect image or a light ring. The rotating disk is mainly used to create an effect similar to a record player. The desired effect image can be set on the rotating disk according to actual needs, thus producing a special visual effect when the disk rotates. Of course, a light ring can also be added to achieve better optical effects. The rotating disk can be made of various materials, such as metal, plastic, wood, etc. To achieve a more realistic effect like a record player, the material and color can be imitated.

[0058] The third transmission gear 61 is connected to the rotating disk, and the third transmission gear drives the rotating disk to rotate.

[0059] When the first transmission gear rotates in the forward direction, it drives the second shaft to move along the meshing adjustment groove toward the direction of the third transmission gear, so that the second transmission gear meshes with the third transmission gear, drives the third transmission gear to rotate, and thus drives the rotating disk to rotate.

[0060] When the first transmission gear rotates in the opposite direction, the first transmission gear drives the second shaft to move away from the third transmission gear along the meshing adjustment groove, so that the second transmission gear and the third transmission gear disengage.

[0061] The data cable is wound on a reel, so that when pulling the cable, the reel drives the first, second, and third drive gears and the rotating disc to rotate. When rewinding the cable, the reel drives the first and second drive gears to rotate, simultaneously disengaging the second and third drive gears, preventing the rotating disc from rotating in reverse. This achieves automatic cable rewinding and unidirectional disc rotation. The rotating disc can be customized with patterns that create special visual effects when rotating, providing a unique decorative effect when the cable is pulled, making the functionality more comprehensive.

[0062] The third rotating shaft 62 is mounted on the module bracket and connected to the third transmission gear. The third rotating shaft is used to support and position the third transmission gear.

[0063] The fourth rotating shaft 71 is mounted on the module support, and the rotating disk is sleeved on the fourth rotating shaft. The fourth rotating shaft is used to support and position the fourth transmission gear.

[0064] The fourth transmission gear 72 is fitted onto the fourth rotating shaft and fixedly connected to the rotating disk. The fourth transmission gear is located below the rotating disk and meshes with the third transmission gear. The third transmission gear meshes with the fourth transmission gear, and the fourth transmission gear is fixedly connected to the rotating disk, so that when the third transmission gear rotates, the fourth transmission gear and the rotating disk can rotate accordingly.

[0065] In this specific embodiment, the side of the winding reel 2 is provided with drive teeth 23. The drive teeth 23 are mainly used to mesh with the first transmission gear, thereby realizing the transmission of force.

[0066] The first transmission gear 32 includes a lower gear 321 and an upper gear 322 arranged vertically; the lower gear and the upper gear are fixedly connected. In this specific embodiment, the lower gear 321 and the upper gear 322 are integrally formed. By arranging the first transmission gear into a vertically arranged lower gear and upper gear, the lateral volume can be reduced.

[0067] The drive gear 23 meshes with the lower gear 321, and the upper gear 322 meshes with the second transmission gear 42.

[0068] In this specific embodiment, the module support 1 includes a base 11, a middle cover 12, and an upper cover 13. Wherein:

[0069] A base shaft 111 is provided on the upper surface of the base 11, and the winding reel 2 is sleeved on the base shaft. In this specific embodiment, the base shaft and the base are integrally formed, and the winding reel can rotate relative to the base shaft.

[0070] The middle cover 12 covers the upper end of the base.

[0071] A receiving cavity 14 is formed between the base 11 and the middle cover 12, and at least one side of the receiving cavity penetrates the side of the base and the middle cover to form a cable outlet 15. The data cable extends through the cable outlet into the receiving cavity and is wound on a cable reel.

[0072] The base shaft 11 is located in the accommodating cavity, and the winding reel 2 is placed in the accommodating cavity 14.

[0073] The upper cover 13 covers the upper end of the middle cover; the first rotating shaft 31 is supported between the base and the middle cover.

[0074] A receiving space 16 is formed between the upper cover 13 and the middle cover 12. The second rotating shaft, the third rotating shaft, the second transmission gear and the third transmission gear are disposed in the receiving space. The upper and lower ends of the second rotating shaft and the third rotating shaft are respectively supported on the middle cover and the upper cover.

[0075] The structure of the base, middle cover and top cover is stacked, which can reduce the lateral length of the winding module and reduce the space occupied in the lateral direction. At the same time, it makes the structure of the winding module more compact and suitable for use in electronic devices.

[0076] The meshing adjustment groove 4 includes a lower meshing adjustment groove 401 disposed on the upper surface of the middle cover and an upper meshing adjustment groove 402 disposed on the lower surface of the upper cover. The lower meshing adjustment groove and the upper meshing adjustment groove are symmetrically arranged facing each other. The upper and lower ends of the second rotating shaft are respectively inserted into the upper meshing adjustment groove and the lower meshing adjustment groove.

[0077] In this specific embodiment, the upper cover 13 is provided with a through hole 131, the fourth transmission gear is inserted into the through hole 131, and the fourth rotating shaft 71 is inserted into the through hole and its lower end is supported on the middle cover.

[0078] In this specific embodiment, a ratchet shaft 121 is provided at the lower end of the middle cover 12; the winding module also includes a reset coil spring 81, a ratchet disc 82, and a ratchet plate 83. Wherein:

[0079] The reset spring 81 is connected to the base and the reel and is used to reset the reel.

[0080] The ratchet disc 82 is fixed to the upper end surface of the winding disc, and the ratchet disc is provided with an annular rotating groove 821 and a blocking recess 822 provided in the rotating groove.

[0081] One end of the ratchet plate 83 is provided with a shaft hole 831, and the lower surface of the other end is provided with a protruding stop shaft 832. The ratchet plate is sleeved on the ratchet shaft through the shaft hole and can rotate relative to the ratchet shaft. The stop shaft is inserted into the rotating groove. When the winding reel rotates relative to the base, the rotating groove rotates around the stop shaft relative to the base, and when the stop shaft is blocked in the blocking recess, it can prevent the winding reel from rotating in the forward direction.

[0082] The reset spring allows the cable reel to automatically reset, thereby automatically winding the data cable onto the reel.

[0083] The ratchet disc and ratchet plate allow the cable reel to be positioned during cable pulling, thus stopping the data cable at multiple predetermined length positions. Users can fix the desired length according to actual needs and trigger the retraction spring after a slight pull to automatically retract the cable. Of course, the ratchet disc and ratchet plate can also be implemented using existing common ratchet structures. This invention is not limited to the specific structure of the ratchet, as long as it can achieve the function of stopping the pulled-out data cable at the desired length.

[0084] Of course, the machine wheel and ratchet plate can be omitted.

[0085] The winding module of this utility model can be used in electronic devices. The electronic device having the winding module includes a data cable 22 with a USB interface and a winding module, wherein the data cable is wound on the winding spool.

[0086] The winding module of this invention can be used in power banks. The power bank includes a data cable with a USB interface and a winding module, wherein the data cable is wound on the winding spool.

[0087] This invention features a cable reel mounted on a module bracket, along with a first transmission gear, an adjustment groove, a second transmission gear, a rotating disk, and a third transmission gear. When the first transmission gear rotates forward, it drives a second rotating shaft to move along the adjustment groove towards the third transmission gear, engaging it and driving the third transmission gear to rotate, thereby driving the rotating disk to rotate. When the first transmission gear rotates in the reverse direction, it drives the second rotating shaft to move along the adjustment groove away from the third transmission gear, disengaging it from the third transmission gear. The data cable is wound on the reel, allowing the reel to drive the first, second, and third transmission gears and the rotating disk to rotate during cable pulling. During cable winding, the reel drives the first and second transmission gears to rotate, simultaneously disengaging the second and third transmission gears and preventing the rotating disk from rotating in reverse. This achieves automatic data cable winding and unidirectional rotation of the rotating disk. The rotating disc can be customized with patterns that create special visual effects when rotating, thus providing a unique decorative effect when the string is pulled, making it more versatile.

[0088] This invention innovates the structure of a retractable cable module inside electronic devices, employing a turntable-style winding system. This system enables automatic cable retraction and unidirectional turntable rotation. The turntable rotates when the cable is extended, and when the cable is retracted, gears slide to avoid reverse drive, preventing the turntable from rotating backward. During cable extension, an internal ratchet structure, combined with a spring and stop design, allows the cable to stop at multiple predetermined length positions. Users can fix the desired length and trigger the retraction spring with a slight pull to complete automatic retraction. The turntable can be combined with a light ring, logo panel, or rotating visual effects to achieve personalized and interactive product design. It is suitable for the compact internal structure of modern power banks, providing a multi-functional integrated solution for cable retraction, display, and energy conversion.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
