Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to providing a cable winding device and a charging device. Background Technology

[0002] Data cables are widely used in various electronic products, such as mobile phone data cables and tablet data cables. To facilitate the storage and carrying of data cables of a certain length, they are typically wound onto a reel in a winding mechanism. When the user needs the data cable, they simply pull out the desired length. To rewind, the reel rotates under the action of a spring in the winding mechanism, thus rewinding the pulled-out cable back onto the reel. However, the existing winding mechanism has the following shortcomings: Firstly, when using the data cable, the user may unintentionally pull too hard, causing the cable to be pulled out too far from the reel. Secondly, when winding the data cable, the spring drives the reel to rotate, gradually increasing the rotation speed of the reel, causing the pulled-out cable end to swing and potentially hit the user or bystanders, seriously affecting the user experience. Therefore, it is necessary to improve the existing winding mechanism. Utility Model Content

[0021] Please see Figure 1-5 As shown, in some embodiments of this utility model, a winding device includes a housing 10, a winding reel 20, and a sound-generating component 30. The winding reel 20 is rotatably mounted inside the housing 10. One end of the winding reel 20 is provided with abutment portion 21, and the outer wall of the abutment portion 21 is provided with a groove 22. The sound-generating component 30 is disposed between the housing 10 and the winding reel 20. The sound-generating component includes abutment member 31 and elastic member 32. One end of the abutment member 31 abuts against the abutment portion 21, and the elastic member 32 connects the abutment member 31 and the housing 10. Optionally, in this embodiment, the abutment portion 21 protrudes along the axial direction of the winding reel 20, and the groove 22 is recessed along the radial direction of the abutment portion 21 on the outer wall of the abutment portion 21 (e.g., ...). Figure 4As shown), the abutment 31 and elastic element 32 in the sound-generating component 30 are arranged perpendicular to the rotation direction of the reel 20. In other embodiments, the specific positions of the abutment 21 and the groove 22 can be set according to actual needs. When the elastic element 32 acts on the abutment 31, it pushes one end of the abutment 31 to elastically abut against the outer wall of the abutment 21. When the reel 20 rotates, one end of the abutment 31 can abut against the outer wall of the abutment 21 or the groove 22. Specifically, when using the winding device, if the reel 20 is wound with a data cable, when a person pulls out the data cable wound on the reel 20, the reel 20 rotates accordingly. Under the action of the elastic element 32, the abutment 31 first abuts against the outer wall of the abutment 21. The abutment 31 abuts against the outer wall of the abutment part 21, and then against the groove 22, repeating this cycle. There is a height difference between the outer wall of the abutment part 21 and the groove 22. The abutment 31 will collide with the groove 22 and make a sound, reminding the user how many fixed angles the reel 20 has rotated. The angle of rotation of the reel 20 corresponds to the length of data cable that has been pulled out. The user can perceive how long the data cable has been pulled out through sound. When the user releases his hand, the reel 20 rotates back. Under the action of the elastic member 32, the abutment 31 still abuts against the outer wall of the abutment part 21 or against the groove 22, which can apply rotational resistance when the reel 20 rotates, reduce the rotational speed, and prevent the data cable head from swinging and hitting the user's hand, thus improving the user experience.

[0022] Please see Figure 2-3 As shown, in one embodiment of this utility model, a receiving groove 11 is provided inside the housing 10. The receiving groove 11 includes a first receiving sub-groove 110 and a second receiving sub-groove 111 connected to the first receiving sub-groove 110. The abutment 21 is housed in the first receiving sub-groove 110, and the sound-generating component 30 is housed in the second receiving sub-groove 111. By separately providing a receiving space inside the housing 10 for accommodating the abutment 21 and the sound-generating component 30, the internal installation space of the housing 10 is optimized, resulting in a compact structure.

[0023] Please see Figure 1-2 As shown, in one embodiment of the present invention, the housing 10 includes a bottom shell 12 and a top shell 13. The top shell 13 has a protrusion 130 on the side away from the bottom shell 12. The receiving groove 11 is provided on the protrusion 130, and the protrusion 130 is provided with a sound transmission port 1300 that communicates with the second receiving sub-groove 111. By providing the sound transmission port 1300, the impact sound inside the housing 10 can be smoothly transmitted to the outside of the housing 10.

[0024] Please see Figure 2-3As shown, in one embodiment of this utility model, the winding device further includes a fixed shaft 50 disposed inside the housing 10, a rotating hole 210 disposed inside the winding reel 20, the rotating hole 210 penetrating the abutment portion 21, and an auxiliary rotating column 1301 disposed at a position corresponding to the rotating hole 210. The winding reel 20 is sleeved on the fixed shaft 50 through the rotating hole 210, and the abutment portion 21 is sleeved on the auxiliary rotating column 1301 through the rotating hole 210. The winding reel 20 rotates more stably inside the housing 10, and the abutment member 31 can stably switch abutment between the outer wall of the abutment portion 21 and the groove 22.

[0025] Please see Figure 2-3 as well as Figure 5 As shown, in one embodiment of the present invention, the second receiving sub-groove 111 includes a first guide surface 1110 and a second guide surface 1111 arranged at intervals and in parallel. The abutting member 31 includes a guided portion 310, which includes a first guided surface 3100 that contacts the first guide surface 1110 and a second guided surface 3101 that contacts the second guide surface 1111. The first guided surface 3100 is guided by the first guide surface 1110, and at the same time, the second guided surface 3101 is guided by the second guide surface 1111. This achieves stable guidance for the linear movement of the abutting member 31 towards or away from the abutting portion 21. The abutting member 31 can stably switch abutting between the outer wall of the abutting portion 21 and the groove 22.

[0026] In some embodiments of this utility model, a first elastic element positioning structure 311 is provided at the end of the abutting member 31 away from the abutting part 21, and a second elastic element positioning structure 312 is provided on the housing 10 corresponding to the position of the abutting member 31. The two ends of the elastic element 32 are respectively connected to the first elastic element positioning structure 311 and the second elastic element positioning structure 312. The first elastic element positioning structure 311 and the second elastic element positioning structure 312 can be a positioning post, a storage groove, or an abutting wall. In this embodiment, please refer to... Figure 2-3 as well as Figure 5 As shown, both the first elastic element positioning structure 311 and the second elastic element positioning structure 312 are positioning posts, while the elastic element 32 is a compression spring. One end of the compression spring is sleeved on the first elastic element positioning structure 311, and the other opposite end is sleeved on the second elastic element positioning structure 312. Under the action of the elastic element 32, the abutment 31 can stably abut against the outer wall of the abutment part 21 or the groove 22. In other embodiments, the first elastic element positioning structure 311 and the second elastic element positioning structure 312 can also be selected as a receiving groove or an abutment wall. The abutment wall can be formed by the inner wall of the component, such as forming an abutment wall on the inner wall of the housing 10.

[0027] Please see Figure 1-2 As shown, in one embodiment of this utility model, the winding device further includes a circuit board 40, which is located inside the housing 10. The sound-generating component 30 is located between the circuit board 40 and the housing 10. The circuit board 40 blocks the opening of the second receiving sub-slot 111, and the second receiving sub-slot 111 forms a stable sound-generating cavity. Please refer to [further details omitted]. Figure 2 As shown, the circuit board 40 has a passage 41 in the middle area, and the abutment part 21 of the coil 20 passes through the passage 41, making the internal installation space of the housing 10 compact.

[0028] Please see Figure 4-5 As shown, in one embodiment of this utility model, the abutting member 31 has an abutting portion 313 at one end that abuts against the abutting portion 21. The abutting portion 313 is tapered near the abutting portion 21. The abutting member 31 can stably switch abutting between the outer wall of the abutting portion 21 and the groove 22. Furthermore, the abutting portion 313 includes a first abutting surface 3130 and a second abutting surface 3131 with a preset angle. The angle between the first abutting surface 3130 and the second abutting surface 3131 is greater than 45 degrees. When the reel 20 rotates, the abutting member 31, under the action of the elastic member 32, can smoothly impact the groove 22. After being removed from the groove 22, the abutment 31 smoothly switches between the outer wall of the abutment portion 21 and the groove 22. In this embodiment, there are three grooves 22, spaced apart along the circumference of the cable reel 20. The abutment 31 makes a sound when it collides with the groove 22, reminding the user that the angle of the cable reel 20 has rotated 120 degrees, indicating that a unit length of data cable has been pulled out of the cable reel 20. In other embodiments, there may be one, two, or more grooves 22. Depending on the number of grooves 22, the angle by which the cable reel 20 rotates can be determined for each sound produced by the collision, thus indicating that a unit length of data cable has been pulled out of the cable reel 20. In this embodiment, each groove 22 also includes an arc surface that abuts against the abutment 31, allowing the abutment 31 to smoothly move out of the groove 22 after impact.

[0029] Another objective of this invention is to provide a charging device, including a charging cable and a winding device as described in any of the preceding claims. One end of the charging cable is wound around the winding reel 20, and the other end extends to the outside of the housing 10. When using this charging device, the user can pull out the desired length of charging cable by sound sensing. After charging is complete, the winding reel 20 rotates, and the abutment member 31, under the action of the elastic member 32, abuts against the outer wall of the abutment part 21 or the groove 22, applying rotational resistance when the winding reel 20 rotates, reducing the rotational speed, and preventing the charging cable head from swinging and hitting the user's hand.

[0030] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
