[0002] A wire winding device is a device that can wind and store a cable in a housing and can pull out the cable when in use, and is often applied to fields such as charging products that require the use of a data cable. The wire winding device usually realizes the automatic recovery of the cable through a torsion spring. Therefore, the recovery speed of the cable is very fast, and violent swinging may occur during the recovery process, posing a safety risk. Especially when the cable has a data connector, the data connector or the data cable is very likely to scratch the outer surface of the device or injure the user when the cable is quickly recovered.

[0005] A cable, part of which is received in the receiving groove, and the cable can be pulled out or recovered;

[0006] A rotating member disposed in the receiving groove, the cable is wound around the rotating member, and the rotating member can rotate as the cable is pulled out or recovered;

[0007] A damping gear rotatably disposed on the housing; and,

[0008] A movable gear movably disposed on the housing;

[0009] Wherein, when the cable is pulled out, the rotating member rotates in a first direction and drives the movable gear to move away from the damping gear, so that the movable gear is separated from the damping gear;

[0010] When the cable is recovered, the rotating member rotates in a second direction opposite to the first direction and drives the movable gear to move towards the damping gear, so that the movable gear meshes with the damping gear.

It can be understood that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0038] The embodiments of the present application provide a wire winding device. Please refer to Figure 1 and Figure 2 , Figure 1 which is a partial perspective structural view of the wire winding device provided by some embodiments of the present application, Figure 2 and Figure 1 is an exploded structural view of a partial wire winding device shown in

[0039] In some embodiments, the wire winding device 10 includes a cable 11 and a rotating member 12. The rotating member 12 is connected to the cable 11. The cable 11 can be wound around the rotating member 12. Part of the cable 11 is received in the wire winding device 10 and can be pulled out or retracted. When the cable 11 is pulled out or retracted, the rotating member 12 can rotate or revolve accordingly. Among them, the rotating member 12 can include a main body 121 and a winding portion 122. The winding portion 122 protrudes from one side surface of the main body 121. The cable 11 is wound around the outer periphery of the winding portion 122, so that when the cable 11 is pulled out or retracted, it can drive the rotating member 12 to rotate like a top.

[0040] The wire winding device 10 may further include a housing 13. The housing 13 may have a receiving groove 101, for example, surrounded to form the receiving groove 101. The cable can be partially received in the receiving groove 101. The rotating member 12 can be disposed in the receiving groove 101. Among them, the rotating member 12 and a part of the cable 11 wound around the rotating member 12 can be received in the receiving groove 101 together. The winding portion 122 can protrude from one side surface of the main body 121 away from the bottom wall of the receiving groove 101. Optionally, a rotating shaft 131 protrudes from one side surface of the housing 13 close to the rotating member 12. The rotating shaft 131 passes through the middle area of the rotating member 12. The rotating member 12 can be rotatably connected to the housing 13 through the rotating shaft 131. In other embodiments, the rotating member 12 can also be rotatably connected to the housing 13 through other structures, such as using an independent shaft body to pass through the middle areas of the housing 13 and the rotating member 12.

[0041] Among them, the winding part 122 can surround and form a receiving groove 102. For example, the winding part 122 can be an annular surrounding wall arranged on the surface of the main body 121. The rotating shaft 131 of the housing 13 can pass through the rotating member 12 and extend into the receiving groove 102, for example, it can extend to the central position of the receiving groove 102. The winding device 10 can further include a reset member 14, and the reset member 14 is used to provide a restoring force for the rotating member 12 to rotate in the reverse direction when the rotating member 12 rotates as the cable 11 is pulled out. The reset member 14 can be selected as a torsion spring. Of course, the reset member 14 can also be other structural members that can provide a restoring force. The reset member 14 can be arranged in the receiving groove 102, and one end is connected to the winding part 122 and the other end is connected to the rotating shaft 131. Among them, the connection manners of the reset member 14 with the winding part 122 and the rotating shaft 131 are, for example but not limited to, clamping, welding, bonding, etc. In some embodiments, the groove wall of the receiving groove 102 can be provided with a notch as Figure 2 shown, and one end of the reset member 14 can be clamped to the winding part 122 through the notch. Similarly, the rotating shaft 131 can be provided with a notch as Figure 2 shown, and the other end of the reset member 14 can be clamped to the rotating shaft 131 through the notch.

[0042] Through the above design, the winding device 10 provided by the embodiment of the present application can drive the rotating member 12 to rotate or revolve by pulling the cable 11. The reset member 14 will gradually store energy during the process of pulling the cable 11. When the pulling force on the cable 11 is lost, the reset member 14 will provide a restoring force to make the rotating member 12 rotate or revolve in the reverse direction, thereby driving the pulled-out cable 11 to automatically retract and be rewound on the rotating member 12.

[0043] The embodiment of the present application also provides an electronic device. Please refer to Figure 3 and Figure 4 , Figure 3 is a three-dimensional structural schematic diagram of the electronic device provided by some embodiments of the present application, Figure 4 is Figure 3 the exploded structural schematic diagram of the electronic device in the embodiment. In the embodiment of the present application, the electronic device 1000 includes a winding device 10.

[0044] In some embodiments, the housing 13 of the winding device 10 can include a first housing 151 and a second housing 152. The first housing 151 and the second housing 152 can be connected to form the housing 13, and the housing 13 can be used as the outer shell of the winding device 10. The rotating member 12 of the winding device 10, a part of the cable 11 wound around the rotating member 12, the reset member 14 and other structural members can all be accommodated in the space surrounded by the first housing 151 and the second housing 152.

[0045] Among them, the first housing 151 may be provided with a receiving groove 101. The first housing 151 can be used to house the rotating member 12. In the embodiments of the present application, the specific structure of the housing 13 can be designed as required. For example, but not limited to the above including the first housing 151 and the second housing 152, and the first housing 151 and the second housing 152 are not limited to the above structure. For example, the receiving groove 101 for housing the rotating member 12 of the wire winding device 10 may be formed in the second housing 152, that is, the second housing 152 may be provided with a surrounding wall. Another example is that both the first housing 151 and the second housing 152 may be provided with surrounding walls.

[0046] In some embodiments, the housing 13 may be provided with a through hole, and the end of the cable 11 may extend outside the housing 13 through the through hole, and the through hole may be opened on the side wall of the receiving groove 101. In some embodiments, one through hole may be opened on the housing 13, and one end of the cable 11 extends outside the housing 13 through the through hole and can be used as a pulling force point. In other embodiments, multiple through holes may be opened on the housing 13, and both ends or multiple segments of the cable 11 may extend outside the housing 13 through two or more through holes, which can be used to connect different devices as needed and can also be used as additional pulling force points. The number of ends of the cable 11 extending outside the housing 13 can be set as required. The structure of the cable 11 can be designed according to the specific application of the wire winding device 10. For example, when the wire winding device 10 is applied to a charging product, a charging connector may be provided at the end of the cable 11 located outside the housing 13.

[0047] In some embodiments, the electronic device 1000 further includes an electronic control mechanism 16, and the electronic control mechanism 16 includes at least one circuit board 160, and the circuit board 160 is electrically connected to one end of the cable 11 of the wire winding device 10. Among them, the cable 11 of the wire winding device 10 can be an electronic data cable for connecting an external device. Optionally, the electronic device 1000 is a power bank. The cable 11 of the wire winding device 10 can be a charging cable. The following will be described by taking the wire winding device 10 as a part of the electronic device 1000 as an example. It should be noted that in other embodiments, the wire winding device 10 can also be applied to other devices, not limited to the electronic device 1000.

[0048] Optionally, the wire winding device 10 may further include a speed reduction mechanism 17 and a stop mechanism 18, which will be specifically described below.

[0050] Please refer to Figure 5 and Figure 6 , Figure 5 is a schematic cross-sectional structure diagram of an electronic device provided in some embodiments of this application. Figure 6 is Figure 5 a partially exploded structure diagram of the electronic device in the embodiment.

[0051] In some embodiments, the main body 121 of the rotating member 12 includes opposite first surface 1211 and second surface 1212. The first surface 1211 is close to the first housing 151, and the second surface 1212 is close to the second housing 152. Among them, the electric control mechanism 16 can be arranged on the first surface 1211 of the main body 121. The winding part 122 protrudes on the second surface 1212 of the main body 121. One end of the cable 11 wound around the winding part 122 can pass through the main body 121 and be electrically connected to the electric control mechanism 16.

[0052] Among them, the electric control mechanism 16 can include a first circuit board 161 and a second circuit board 162. The first circuit board 161 can be arranged on the rotating member 12, and the second circuit board 162 can be arranged on the housing 13. When the cable 11 is pulled, the first circuit board 161 and the second circuit board 162 can be conducted through relative rotation. Among them, at least one of the first circuit board 161 and the second circuit board 162 is electrically connected to one end of the cable 11. Optionally, the first circuit board 161 is arranged on the first surface 1211 of the main body 121, and the second circuit board 162 is arranged on the surface of the first housing 151 facing the main body 121. The first circuit board 161 and the second circuit board 162 can be conducted through relative rotation. Optionally, a groove can be provided on the first surface 1211 of the main body 121, and the first circuit board 161 can be embedded in the groove.

[0053] Among them, the second circuit board 162 can be a slip ring conductive PCB board, and the first circuit board 161 is provided with a corresponding connector. When the cable 11 is pulled out, the rotating member 12 can drive the first circuit board 161 to rotate, so that the first circuit board 161 is conducted after relative rotation with the second circuit board 162, and then the electronic control mechanism 16 can control the pulled-out cable 11 to realize functions such as charging and data transmission.

[0054] In some embodiments, the rotating member 12 can include a winding portion 122 and a meshing portion 123 that are fixed to each other. The meshing portion 123 can be arranged on the main body 121. The meshing portion 123 can include a plurality of convex teeth arranged along the circumferential direction of the main body 121. The meshing portion 123 can be arranged on the first surface 1211 of the main body 121. Among them, the meshing portion 123 can be annular, and the first circuit board 161 can be embedded in the groove inside the meshing portion 123. The meshing portion 123 can be used to drive the corresponding components in the above-mentioned reduction mechanism 17 and stop mechanism 18 to rotate or move.

[0055] Please refer to Figure 7 and Figure 8 , Figure 7 are partial structural schematic diagrams of an electronic device provided in some embodiments of the present application. Figure 8 is Figure 7 The structural schematic diagram of the partial electronic device in another state shown. The coiling device 10 can realize the state switching from the state as shown in Figure 7 to the state as shown in Figure 8 by pulling out or retracting the cable 11.

[0056] The coiling device 10 includes a movable gear 171 and a damping gear 172. The movable gear 171 and the damping gear 172 can form the above-mentioned reduction mechanism 17. Among them, the movable gear 171 is movably arranged on the housing 13. When the rotating member 12 rotates as the cable 11 is pulled out or retracted, it can drive the movable gear 171 to move. The damping gear 172 can rotate or revolve relative to the housing 13. Optionally, the movable gear 171 is meshed and connected with the rotating member 12. The movable gear 171 can be arranged close to the damping gear 172. In other embodiments, the rotating member 12 can also drive the movable gear 171 to move in a manner other than meshing transmission, such as but not limited to pushing.

[0057] Among them, the movable gear 171 can be meshed with the meshing portion 123 of the rotating member 12. The damping gear 172 is spaced apart from the meshing portion 123. The meshing portion 123 can be as shown in Figure 7is disposed on the first surface 1211 of the main body 121 of the rotating member 12 as shown. The movable gear 171 and the damping gear 172 can be spaced apart from the first surface 1211 to avoid being driven by the rotation or revolution of the main body 121. Of course, the movable gear 171 and the damping gear 172 can also abut against the first surface 1211. It should be noted that the rotating member 12 can be a structural member wound by the cable 11 as Figure 7 shown, so that the rotating member 12 can rotate as the cable 11 is pulled or retracted. The rotating member 12 can also be other structural members that can rotate as the cable 11 is pulled or retracted, such as a gear or other structural members connected to the rotating member 12.

[0058] It should be noted that, in this embodiment, the meshing portion 123 for meshing with the movable gear 171 is disposed on the first surface 1211 of the main body 121 to improve the utilization rate of the radial space of the wire winding device 10. In other embodiments, the meshing portion 123 can also be disposed at other positions, such as on the second surface 1212 of the main body 121 or on the circumference of the main body 121.

[0059] When the cable 11 is pulled, the rotating member 12 can rotate in the first direction and drive the movable gear 171 to move away from the damping gear 172, so that the movable gear 171 is separated from the damping gear 172, thereby avoiding increasing the resistance when the cable 11 is pulled. Among them, the first direction is Figure 7 the counterclockwise direction shown. Figure 7 The wire winding device 10 shown can pull the cable 11, so that the rotating member 12 rotates in the counterclockwise direction, so that the movable gear 171 is as Figure 8 shown and moves to a position separated from the damping gear 172.

[0060] It can be understood that when the cable 11 is retracted, the rotating member 12 rotates in the second direction opposite to the first direction and drives the movable gear 171 to move toward the damping gear 172, so that the movable gear 171 meshes with the damping gear 172 to increase the resistance when the rotating member 12 rotates, thereby slowing down the retraction speed of the cable 11. Among them, the second direction is Figure 8 the clockwise direction shown. Figure 8 The wire winding device 10 shown can retract the cable 11, so that the rotating member 12 rotates in the clockwise direction, so that the movable gear 171 is as Figure 7 shown and moves to a position meshing with the damping gear 172.

[0061] The damping gear 172 is used to provide rotational damping. When the movable gear 171 is meshed with the damping gear 172, the damping gear 172 can be connected to the rotating member 12 through the movable gear 171, so that the rotational damping provided by the damping gear 172 can slow down the rotation speed of the rotating member 12. The rotational damping generation method of the damping gear 172 can be selected according to actual conditions. For example, the damping gear 172 can be pressed against another structural member, so that the damping gear 172 will rub against the structural member when it is meshed with the movable gear 171 and rotates; for another example, the damping gear 172 can be rotated by means of a shaft, and the rotational damping of the damping gear 172 can be adjusted by adjusting the roughness or installation tightness of the shaft.

[0062] It can be understood that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0063] See also Figure 9 and Figure 10 , Figure 9 is a partial structural schematic diagram of a wire winding device provided in some embodiments of the present application, Figure 10 yes Figure 9 The schematic diagram of the structure of the partial winding device shown in another state.

[0064] The movable gear 171 and the damping gear 172 can be arranged on the housing 13. The movable gear 171 can be movably arranged on the housing 13, for example, it can be slidably arranged on the surface of the housing 13 facing the rotating member 12, or it can be arranged on the track of the housing 13 facing the rotating member 12. The damping gear 172 can be rotatably arranged on the housing 13. The damping gear 172 can be rotatably connected to the housing 13, or it can be rotatably connected to another structural member and located on the housing 13.

[0065] It should be noted that when a device (such as but not limited to the rotating member 12, the movable gear 171, the damping gear 172, etc.) is described herein as being disposed on the housing 13, it means that it is disposed on a certain part of the housing 13, such as being disposed on the first housing 151, but is not limited thereto. In some embodiments, the device disposed on the housing 13 may be disposed on the first housing 151; in other embodiments, the device disposed on the housing 13 may be disposed on other parts of the housing 13, such as the second housing 152. The device may be disposed on the housing 13 in such a manner that it is in direct contact with the housing 13 or connected to the housing 13 through another connecting member.

[0066] In some embodiments, a sliding track 103 may be provided on the housing 13. The movable gear 171 is disposed on the sliding track 103 and is configured to move along the sliding track 103 under the drive of the rotating member 12. The sliding track 103 may be used to limit the movement trajectory of the movable gear 171. Among them, the movable gear 171 may be separated from the damping gear 172 at one end of the sliding track 103 and engaged with the damping gear 172 at the other end of the sliding track 103.

[0067] Please refer to the above in conjunction with Figure 11 and Figure 12 , Figure 11 is a schematic cross-sectional structure diagram of a partial wire winding device provided in some embodiments of the present application, Figure 12 is Figure 11 a schematic cross-sectional structure diagram of the partial wire winding device shown in another state.

[0068] When the cable 11 is pulled, the rotating member 12 can drive the movable gear 171 from one end of the sliding track 103 close to the damping gear 172, as shown in Figure 11 , to the other end of the sliding track 103 away from the damping gear 172, as shown in Figure 12 . At this time, the movable gear 171 is separated from the damping gear 172. When the movable gear 171 moves to the end of the sliding track 103, the end of the sliding track 103 can prevent the movable gear 171 from further moving in this moving direction. As the cable 11 is further pulled, the movable gear 171 can rotate on its own at this end of the sliding track 103 under the drive of the engaging portion 123.

[0069] When the cable 11 is retracted, the rotating member 12 can drive the movable gear 171 from the end of the sliding track 103 away from the damping gear 172 to the end of the sliding track 103 close to the damping gear 172. At this time, the movable gear 171 is engaged with the damping gear 172. The rotation or revolution of the rotating member 12 will drive the damping gear 172 to rotate or revolve through the movable gear 171, so as to receive the rotational damping provided by the damping gear 172. Similarly, when the movable gear 171 moves to the end close to the damping gear 172 along the sliding track 103, as the cable 11 is further retracted, the movable gear 171 can rotate on its own at this position and drive the damping gear 172 to rotate.

[0070] Among them, the transmission between the engaging portion 123, the movable gear 171, and the damping gear 172 is all realized by gear transmission through the engagement of teeth. The wire winding device 10 can adjust the gear transmission ratio by adjusting the number of teeth of the three, so as to control the deceleration efficiency.

[0071] Please refer to Figures 13 to 15 , Figure 13is a schematic diagram of a partially exploded structure of an electronic device provided in some embodiments of the present application, Figure 14 yes Figure 13 A schematic diagram of the assembly structure of the electronic device in the embodiment, Figure 15 yes Figure 14 A schematic diagram of the assembly structure of an electronic device in another state is shown.

[0072] In some embodiments, the sliding track 103 is formed by a through hole provided on the housing 13. The sliding track 103 may be a bar-shaped through hole or an arc-shaped through hole provided on the housing 13. The movable gear 171 may be partially inserted into the sliding track 103, so that the movable gear 171 may move along the sliding track 103, and when moving to the end of the sliding track 103, it may touch the through hole wall to avoid further movement.

[0073] The movable gear 171 may include a gear portion 1711 and a sliding portion 1712. The gear portion 1711 is meshed with the rotating member 12. The gear portion 1711 may be used to separate or mesh with the damping gear 172 (e.g. Figure 11 and Figure 12 As shown in FIG. 1 , the sliding portion 1712 is protruded from the gear portion 1711 and inserted into the sliding track 103. The sliding portion 1712 can slide in contact with the hole wall of the through hole forming the sliding track 103, and stop at the hole wall of the through hole when moving to the end of the sliding track 103.

[0074] It should be noted that the sliding track 103 in this embodiment is only an example, and the sliding track 103 in the embodiment of the present application is not limited to the above structure. For example, the sliding track 103 can be formed by a groove provided on the housing 13; the movable gear 171 can move along the extension direction of the groove and stop at the side wall of the groove. For another example, the sliding track 103 can be formed by a convex portion provided on the housing 13, and the two ends of the convex portion can be provided with protrusions for stopping the movable gear 171; the movable gear 171 can be embedded in the convex portion and move along the extension direction of the convex portion.

[0075] In some embodiments, the housing 13 may be provided with a mounting groove 104. The damping gear 172 may be accommodated in the mounting groove 104, so that the groove wall of the mounting groove 104 may serve as a barrier to prevent the damping gear 172 from being disengaged from the installed position. Figure 13 As shown, a mounting portion 132 is provided. The mounting portion 132 is a hollow structure. The inner space of the mounting portion 132 can be as shown. Figure 14Form an installation groove 104 as shown. The notch of the installation groove 104 faces away from the rotating member 12, so that the groove wall of the installation groove 104 can prevent the damping gear 172 from falling off in the direction close to the rotating member 12. An opening 105 communicating with the installation groove 104 is formed on the wall body of the installation part 132 close to the sliding track 103, and the damping gear 172 can be meshed with the movable gear 171 through the opening 105.

[0076] Among them, the damping gear 172 can be rotatably connected to the housing 13. Specifically, it can be realized by inserting its own shaft body into the housing 13 or sleeving on the shaft body protruding from the housing 13 to achieve rotational connection with the housing 13. The damping gear 172 can be prevented from falling off from the notch of the installation groove 104 through its connection with the housing 13. In some embodiments, other structural members can also be provided in the installation groove 104 to abut against the damping gear 172 to prevent the damping gear 172 from falling off from the notch of the installation groove 104.

[0077] It should be noted that the above structure of the installation groove 104 is only an example provided in this embodiment. In other embodiments of the present application, the installation groove 104 can also be of other structures. For example, the installation groove 104 can be recessed on the surface of the housing 13 facing the rotating member 12, its notch can face the rotating member 12, and the installation part 132 can form the side wall of the installation groove 104.

[0078] Please refer to Figure 16 and Figure 17 , Figure 16 which is a schematic assembly structure diagram of a partial winding device provided in some embodiments of the present application, Figure 17 is Figure 16 a schematic exploded structure diagram of the partial winding device shown.

[0079] In some embodiments, the winding device 10 can include a damping pad 173. The damping pad 173 can be arranged on the housing 13 and abuts against the damping gear 172 to increase the rotational damping of the damping gear 172. Specifically, when the damping gear 172 rotates while meshing with the movable gear 171, it will rub against the damping pad 173, thereby providing greater rotational damping. The shape and material of the damping pad 173 can be set as needed, such as but not limited to a rubber sheet.

[0080] Among them, the damping pad 173 can be arranged in the installation groove 104 and abut against the damping gear 172. The shape of the damping pad 173 can be adapted to the shape of the notch of the installation groove 104. The damping pad 173 can be installed at the notch of the installation groove 104 and have an interference fit with the groove wall of the installation groove 104, so that the damping pad 173 can also be used to prevent the damping gear 172 from falling off from the notch of the installation groove 104. The damping pad 173 can be smoothly transitioned with the surface of the housing 13 on the side facing away from the rotating member 12.

[0081] Understandably, the damping pad 173 can also be connected to the housing 13 by means such as, but not limited to, adhesion. In other embodiments, the damping pad 173 can also be arranged at other positions in the mounting groove 104, for example, between the groove wall of the mounting groove 104 and the damping gear 172, and abut against the damping gear 172.

[0082] Please refer to Figure 18 and Figure 19 , Figure 18 FIG. is a schematic cross-sectional structure diagram of a wire winding device provided in some embodiments of the present application, Figure 19 is Figure 18 a schematic cross-sectional structure diagram of the wire winding device shown in another state.

[0083] In some embodiments, a stop track 106 can be provided on one side surface of the housing 13 close to the rotating member 12. The wire winding device 10 includes a stop mechanism 18. The stop mechanism 18 can be in transmission connection with the engagement portion 123 and abut against the stop track 106. The stop mechanism 18 can move along the stop track 106 as the rotating member 12 rotates. Among them, the stop track 106 and the stop mechanism 18 can be configured such that when the cable 11 is pulled to a preset length, the stop mechanism 18 abuts against a preset position on the stop track 106 and abuts against the engagement portion 123 to counteract the force of the rotating member 12 rotating in the reverse direction under the action of the reset member 14.

[0084] Optionally, the stop mechanism 18 can include a swing member 181. The swing member 181 can be rotatably connected to the housing 13. The swing member 181 is swingably connected to the engagement portion 123 and swings when the engagement portion 123 rotates. Specifically, one end of the swing member 181 can abut against the engagement portion 123 and, as the engagement portion 123 rotates, switch between a state where it is lifted by the convex teeth of the engagement portion 123 as shown in Figure 18 and a state where it is embedded between two convex teeth of the engagement portion 123 as shown in Figure 19 through swinging.

[0085] The stop mechanism 18 can further include a spring piece 182. The spring piece 182 can be fixed to the housing 13 by means such as, but not limited to, clamping. The spring piece 182 can abut against the swing member 181. Thus, when the swing member 181 switches states through swinging, the spring piece 182 can switch from a deformed state as shown in Figure 18 to a reset state as shown in Figure 19 to emit a sound, and this sound can be used as a prompt sound. The spring piece 182 is, for example but not limited to, a metal piece.

[0086] Please refer to Figure 18 and Figure 19 for further reference to Figure 20 and Figure 21 ,Figure 20 Yes Figure 18 Schematic diagram of the state change of the stop mechanism in the embodiment Figure 21 Yes Figure 18 Schematic diagram of the state change of a part of the wire winding device in the embodiment Figure 20 The three states shown correspond one-to-one with Figure 21 the three states shown

[0087] In some embodiments, a strip-shaped chute 107 is provided on one side of the swing member 181 facing the housing 13 as Figure 20 shown. The stop mechanism 18 further includes a stop member 183. One end of the stop member 183 is located in the strip-shaped chute 107 and presses against the swing member 181; the other end of the stop member 183 is located in the stop track 106 as Figure 21 shown and presses against the housing 13. Among them, a boss 1831 can be provided on the circumferential side between the two sections of the stop member 183, and the boss 1831 can abut against the surface of the housing 13 provided with the stop track 106 to prevent the stop member 183 from tipping over during movement

[0088] Among them, a limiting portion 133 is provided at a preset position of the stop track 106. When the wire winding device 10 pulls out the cable 11, the stop mechanism 18 moves along the stop track 106 as the rotating member 12 rotates. When the cable 11 is pulled out to the preset length, the stop mechanism 18 can abut against the limiting portion 133 at the preset position of the stop track 106 and also abut against the engaging portion 123

[0089] Specifically, the swing member 181 can swing as the rotating member 12 rotates, and drive the stop member 183 to move along the stop track 106 through the groove wall of the strip-shaped chute 107. The stop member 183 of the stop mechanism 18 can move along the stop track 106 as Figure 21 shown as the swing member 181 swings, and can move along the strip-shaped chute 107 on the swing member 181 synchronously as Figure 20 shown. When the cable 11 is pulled out to the preset length, the swing member 181 swings to state three as Figure 20 shown, and the stop member 183 moves along the stop track 106 to the preset position of state three as Figure 21 shown and abuts against the limiting portion 133. The elastic piece 182 can be used to make a sound due to shape recovery when the stop member 183 reaches the preset position. When the cable 11 is pulled out to the preset length, the swing member 181 can swing to reset the elastic piece 182 so that the elastic piece 182 makes a sound

[0090] Among them, the limiting part 133 can be formed by two opposite arc-shaped protrusions and the depression between the two protrusions in the stop track 106. The stop member 183 abutting against the limiting part 133 can prevent the swing member 181 from swinging in the reverse direction by pressing the swing member 181, thereby preventing the reset member 14 from driving the rotating member 12 to rotate in the reverse direction, so that the cable 11 pulled out by a preset length will not automatically retract. The winding device 10 can further pull the cable 11 to make the stop member 183 move further along the stop track 106 and leave the limiting part 133 to eliminate the above stop state. In other embodiments, the winding device 10 can be provided with one or more limiting parts 133 on the stop track 106 as needed.

[0091] The winding device 10 provided by the embodiment of the present application can drive the movable gear 171 to move through the engaging part 123 of the rotating member 12 to decelerate when retracting the cable 11, avoid excessive resistance when pulling the cable 11, and can also drive the swing member 181 to swing through the engaging part 123 to push the stop member 183 to move cyclically along the stop track 106 to complete stopping and releasing.
