[0001] The present application relates to the field of wire storage equipment, and in particular to a wire winder. Background Art

[0002] With the widespread use of electronic devices in daily life and industrial production, connecting cables such as charging cables and data cables have become indispensable accessories. To meet the needs of multiple scenarios, these cables are usually designed to be 2 meters, 3 meters or even longer. However, cables that are too long take a long time to wind. However, the current common way to store cables mainly relies on manual winding and then fixing them with Velcro. This method has obvious shortcomings when dealing with longer cables: the winding process is time-consuming and inconvenient to operate. Especially in situations where cables need to be frequently retracted and released, the efficiency and user experience of this storage method need to be improved urgently.

[0003] To this end, the above problems need to be solved. Summary of the Invention

[0004] The present application provides a wire winder to solve the problem that manual wire winding of a traditional wire winder is time-consuming and inconvenient to operate.

[0005] In the first aspect, a wire winder comprises an upper shell and a lower shell both of which are hollow inside, the upper shell and the lower shell being coaxially arranged and connected for relative rotation via a rotating connection; a planetary gear assembly is provided in the lower shell, the planetary gear assembly comprising: a sun gear having a central axis and connected to a wire cavity in the upper shell via the central axis; at least one planetary gear uniformly distributed circumferentially and simultaneously meshed with the outer periphery of the sun gear; a ring gear fixedly arranged on the inner side wall of the lower shell and meshed with all the planetary gears.

[0006] Furthermore, the planetary gear assembly also includes planet carriers with the same number as the planetary gears, each planet carrier passes through the corresponding planetary gear and forms a rotational connection therewith, and the upper and lower ends of each planet carrier are respectively fixed to the inner walls on both sides of the lower shell in the upper and lower directions.

[0007] Furthermore, the number of teeth of the sun gear is smaller than the number of teeth of the planetary gears.

[0008] Furthermore, the number of teeth of the ring gear is greater than the number of teeth of the planetary gears.

[0009] Furthermore, the rotary connection portion includes a first groove provided below the upper shell, and a boss located at the lower shell and arranged along the circumference of the lower shell and assembled corresponding to the first groove.

[0010] Furthermore, an upper partition plate and a lower partition plate are provided in the upper shell, and the upper partition plate and the lower partition plate together form the line cavity; the lower partition plate is provided with a second groove on the downward side, and the side wall of the second groove is provided with a serrated portion; it includes a ratchet transmission member, which is installed in the assembly space enclosed by the second groove and the upper shell; the central axis passes through the upper shell and is exposed in the assembly space to form an extended end; the center of the ratchet transmission member is connected to the extended end, and the end of the ratchet transmission member is meshed and connected with the serrated portion.

[0011] Furthermore, the extension end has at least one cut surface, forming a non-circular cross-section; the center of the ratchet transmission member has an anti-rotation hole, and the inner contour of the anti-rotation hole fits the cut surface to limit relative rotation.

[0012] Furthermore, the ratchet transmission member includes a plurality of pawls, the inner ends of each pawl are intersected and connected, while the outer ends are not connected to each other.

[0013] Furthermore, the serrated portion has a gently sloping surface and a vertical surface, and a tooth groove is formed at the connection between the gently sloping surface and the vertical surface, and the end of the pawl is embedded in the tooth groove.

[0014] Furthermore, the upward side of the partition plate cooperates with the top of the upper shell to form a winding area for assembling wires.

[0015] Furthermore, the side of the upper shell has a wire outlet hole, and the top of the upper shell has a wire inlet hole.

[0016] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0017] The cable winder of this technical solution optimizes the wire storage process by adopting a planetary gear transmission mechanism. The cable winder is mainly composed of an upper shell and a lower shell, and mechanical transmission is achieved through a planetary gear set (including a sun gear, planetary gears and a fixed ring gear). In detail, when the user rotates the lower shell, the ring gear fixed on the inner side of the lower shell will drive the planetary gear engaged with it to rotate, and the planetary gear in turn drives the sun gear to rotate; because the central axis of the sun gear is linked to the upper shell, it eventually drives the upper shell to rotate to achieve automatic winding of the wire. This transmission design makes the winding operation easy and labor-saving, and it can be completed by just rotating. It effectively solves the problem that the traditional manual winding method is time-consuming and inconvenient to operate. It is particularly suitable for use scenarios where long cables need to be frequently retracted and released. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0033] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0034] In order to solve the problem that the traditional manual winding method is time-consuming and inconvenient to operate, the inventor provides a wire winder to solve the problem of inconvenient wire winding.

[0035] A wire winder according to the present technical solution, such as Figure 1 、 Figure 2 、 Figure 8As shown, it includes an upper shell 1 and a lower shell 2, both of which are hollow inside. The upper shell 1 and the lower shell 2 are coaxially arranged and connected with each other by a rotating connection part 3. The side of the upper shell 1 has a wire outlet hole 16, and the top of the upper shell 1 has a wire inlet hole 17. The wire inlet hole 17 is used for inserting the power cord of an external device (such as a car charger, etc.), and the wire outlet hole 16 is used for extending the power cord (for example, for charging a mobile phone), so that the user can pull out the power cord to a certain length as needed for easy use.

[0036] In addition, if Figure 3 As shown, the rotary connection portion 3 includes a first groove 31 provided below the upper shell 1 , and a boss 32 corresponding to the first groove 31 and located at the lower shell 2 and arranged along the circumference of the lower shell 2 .

[0037] It should be understood that when the lower housing 2 is driven by an external force, its boss 32 will slide relative to the groove wall of the first groove 31 of the upper housing 1, thereby driving the lower housing 2 to rotate relative to the upper housing 1. This precise mechanical linkage lays the foundation for the subsequent transmission of the planetary gear assembly 4.

[0038] like Figure 3 、 Figure 4 and Figure 5 As shown, a planetary gear assembly 4 is provided in the lower housing 2, and the planetary gear assembly 4 includes: a sun gear 41, having a central axis 411, and connected to the linear cavity 13 in the upper housing 1 through the central axis 411; at least one planetary gear 42, uniformly distributed circumferentially and simultaneously meshed with the outer periphery of the sun gear 41; a ring gear 43, fixedly provided on the inner side wall of the lower housing 2, and meshed with all the planetary gears 42.

[0039] When the user rotates the lower shell 2 clockwise (from right to left), the rotational action is transmitted to the planetary gear 42 through the ring gear 43 fixed to the inner wall of the lower shell 2, causing the planetary gear 42 to rotate clockwise (from right to left). Since the planetary gear 42 and the sun gear 41 are meshed with each other, according to the principle of gear transmission, the sun gear 41 will produce a counterclockwise rotation in the opposite direction (from left to right). The sun gear 41 is fixedly connected to the wire cavity 13 in the upper shell 1 through the central axis 411, thereby driving the wire cavity 13 to rotate counterclockwise synchronously. This series of mechanical transmissions ultimately enables the wire inside the upper shell 1 to be automatically and smoothly wound and stored with the wire feed hole 17 as the center. This design cleverly utilizes the reverse transmission mechanism of the planetary gear 42 to efficiently convert the user's rotational action into a winding motion, which is easy to operate. In addition, this design ensures the efficient transmission of rotational power from the lower shell 2 to the planetary gear 42 group and then to the upper shell 1, providing a stable and reliable mechanical transmission guarantee for the entire winding process. This effectively solves the problem in the prior art that manual wire winding is time-consuming and inconvenient to operate.

[0040] like Figure 3 As shown, there are three planetary gears 42 , and the three planetary gears 42 are meshed with the sun gear 41 and the ring gear 43 respectively.

[0041] In this embodiment, when the user rotates the lower housing 2 clockwise, the ring gear 43 on the lower housing 2 drives the three planetary gears 42 to rotate simultaneously. It should be understood that the structural layout of the three planetary gears 42 ensures that when the planetary gears 42 drive the sun gear 41 to rotate, there are three meshing points along the circumference of the sun gear 41. This ensures that the force applied to the sun gear 41 is uniform, thereby improving the rotational stability of the sun gear 41.

[0042] In some usage scenarios where the rotation speed of the sun gear 41 is increased by reducing torque, as long as the number of teeth of the sun gear 41 is less than the number of teeth of the ring gear 43, the number of planetary gears 42 can include one, two, three or even four, as long as the assembly requirements can be met.

[0043] Furthermore, to prevent the planetary gears 42 from axially jumping and radially shifting during rotation, thereby affecting the normal operation of the entire winder, the planetary gear assembly 4 further includes a planetary carrier 44 having the same number as the planetary gears 42. Each planetary carrier 44 extends through a corresponding planetary gear 42 and is rotationally connected thereto. The upper and lower ends of each planetary carrier 44 are respectively fixed to the inner walls of the lower housing 2 on opposite sides in the vertical direction.

[0044] It should be understood that because the upper and lower ends of each planetary carrier 44 are respectively fixed to the upper and lower inner walls of the lower housing 2 and extend through the center holes of the corresponding planetary gears 42, the planetary gears 42 are precisely positioned between the inner walls of the upper and lower housings 2. This design completely constrains the axial (vertical) movement of the planetary gears 42, effectively preventing axial movement of the planetary gears 42 during high-speed rotation. Furthermore, the planetary gears 42 can only rotate around the fixed planetary carrier 44, effectively preventing radial deviation of the planetary gears 42.

[0045] Furthermore, in order to achieve rapid winding and storage of the wire, the number of teeth of the sun gear 41 is smaller than the number of teeth of the planetary gears 42 .

[0046] In a specific embodiment, for example, the number of teeth of the sun gear 41 is preset to be 10, and the number of teeth of the planetary gear 42 is preset to be 20. According to the gear transmission ratio formula, when the planetary gear 42 serves as the driving gear and the sun gear 41 serves as the driven gear, the transmission ratio is 20 / 10=2, that is, the planetary gear 42 rotates 1 circle and the sun gear 41 needs to rotate 2 circles. If the planetary gear 42 is manually driven to rotate N circles, the sun gear 41 rotates 2N circles, thereby improving the winding efficiency.

[0047] To further increase the winding speed, the number of teeth on the ring gear 43 is set to three times that of the planetary gear 42, i.e., 60 teeth, forming a three-stage transmission structure of "ring gear 43-planetary gear 42-sun gear 41": when the lower housing 2 is manually driven to rotate the ring gear 43 by one circle, the transmission ratio between the ring gear 43 and the planetary gear 42 is 60 / 20=3 through internal meshing transmission, i.e., the planetary gear 42 rotates three circles; while the transmission ratio between the planetary gear 42 and the sun gear 41 remains at 2, so that the sun gear 41 rotates 3×2=6 circles, i.e., the winder completes 6 windings. Thus, through the three-stage transmission, the rotation of one circle at the driving end (i.e., at the ring gear 43) is converted into the rotation of six circles at the winding end (i.e., at the line cavity 13 connected to the sun gear 41), which significantly increases the winding speed.

[0048] It should be noted that in this technical solution, in order to achieve the function of fast winding, the solution adopted is to increase the rotation speed of the sun gear 41 by reducing the torque, that is, the number of teeth of the sun gear 41 is less than the number of teeth of the planetary gears 42. In other specific usage scenarios, it is necessary to use a solution of reducing the rotation speed of the sun gear 41 by increasing the torque to achieve the situation of reducing the winding speed. In this case, the planetary gear assembly 4 also includes a scenario in which the number of teeth of the intermediate sun gear 41 is greater than the number of teeth of the planetary gears 42. This technical solution does not make specific and size restrictions on the number of teeth of the sun gear 41, the number of teeth of the planetary gears 42, and the number of teeth of the ring gear 43. The number of teeth of the sun gear 41, the planetary gears 42, and the ring gear 43 can be flexibly adjusted according to actual winding requirements, mechanical load and other factors. The tooth number configuration is only an example. In the field of winding, the tooth ratio of the sun gear 41 and the planetary gears 42 can be flexibly arranged according to the requirements of the winding speed.

[0049] like Figure 6 、 Figure 7 and Figure 8 As shown, in another usage scenario, for example, during the winding process, if the sun gear 41 reverses, the wire will be wound in the reverse direction, resulting in uneven winding. In order to solve this technical pain point, the present solution provides a ratchet transmission component 5 in the wire cavity 13 to achieve non-interference between the wire pulling and winding functions. Specifically: when winding, the ratchet transmission component 5 can lock the rotation direction of the sun gear 41 to prevent it from reversing; and when it is necessary to pull the wire, the ratchet transmission component 5 allows the sun gear 41 to rotate unidirectionally to avoid interference between the wire pulling process and the winding effect. This design effectively solves the problem of uneven wire caused by reverse winding through the one-way transmission characteristics of the ratchet transmission component 5, ensuring the stability and reliability of the winding operation.

[0050] In detail, an upper partition plate 11 and a lower partition plate 12 are provided in the upper shell 1, and the upper partition plate 11 and the lower partition plate 12 together form a linear cavity 13; a second groove 14 is provided on the downward side of the lower partition plate 12, and a serrated portion 15 is provided on the side wall of the second groove 14; it includes a ratchet transmission member 5, which is installed in the assembly space 6 enclosed by the second groove 14 and the upper shell 1; the central axis 411 passes through the upper shell 1 and is exposed in the assembly space 6 to form an extension end 412; the center of the ratchet transmission member 5 is connected to the extension end 412, and the end of the ratchet transmission member 5 is meshed and connected with the serrated portion 15.

[0051] In the structural design of this wire winder, a closed wire cavity 13 is formed inside the upper shell 1 by the upper partition plate 11 and the lower partition plate 12, and a serrated portion 15 is provided on the side wall of the second groove 14 on the bottom surface of the lower partition plate 12, which forms a one-way transmission mechanism with the ratchet transmission member 5 in the installation and assembly space 6. When the wire is manually pulled from the side of the shell, the pulling force drives the lower partition plate 12 to rotate, thereby driving the serrated portion 15 to rotate synchronously. At this time, the ratchet transmission member 5 connected to the extension end 412 of the central axis 411 of the sun gear 41 rotates with the serrated portion 15, but due to its special meshing structure (its end is meshed and connected with the serrated portion 15), it slips and idles in the clockwise direction (the direction of pulling the wire), so that the pulling force cannot be transmitted to the sun gear 41 through the extension end 412. This slipping mechanism effectively isolates the influence of the wire pulling operation on the transmission system, ensures that the sun gear 41 remains stationary during the wire pulling process, and avoids the disorder of the wire winding caused by reverse drive. By physically decoupling the winding and pulling functions on the transmission path, this design fundamentally solves the common interference problem of forward and reverse operations in traditional winders, significantly improving the flatness and reliability of wire storage.

[0052] More specifically, the ratchet transmission member 5 includes multiple pawls 52. The inner ends of each pawl 52 intersect and connect, while the outer ends are disconnected. This design saves material and is lighter than a gear connection. The serrated portion 15 has a gently sloping surface 151 and a vertical surface 152. The junction of the gently sloping surface 151 and the vertical surface 152 defines a tooth groove 153, into which the ends of the pawls 52 engage.

[0053] It should be understood that when the wire is being pulled, the serrated portion 15 rotates with the pulling force, and its vertical surface 152 is subjected to a force that gives a pushing force to the pawl 52. The pawl 52 is moved toward the gentle slope surface 151 under the pushing force, so that the pawl 52 disengages from the tooth groove 153, and under the guidance of the gentle slope surface 151, moves to the next tooth top connected to the vertical surface 152, and after passing the tooth top, falls into the next tooth groove 153 along the vertical surface 152. As the pulling force further drives, the pawl 52 disengages from the next tooth groove 153 and enters the next gentle slope surface 151. This cycle is repeated. When the pawl 52 contacts the gentle slope surface 151, the slope of the gentle slope surface 151 will dump the pulling force. With this design, the ratchet transmission component 5 can slip in the assembly space 6. At this time, the pulling force of the wire cannot be transmitted to the sun gear 41 through the extension end 412.

[0054] The detailed movement process is as follows: the lower partition plate 12 rotates as the wire is pulled and drives the serrated portion 15 to rotate synchronously. At this time, the vertical surface 152 of the serrated portion 15 pushes the outer end of the pawl 52 to try to drive the ratchet transmission member 5 to rotate; however, since the pawl 52 is connected to the extension end 412, the tangential force generated by the serrated portion 15 is decomposed into a vertical pressing force and a horizontal thrust. The setting of the inclination angle of the gentle slope 151 (for example, 30° to 45°) makes the horizontal component of force greater than the friction between the pawl 52 and the tooth groove 153, forcing The pawl 52 slides along the slope and disengages from the current tooth groove 153; as the serrated portion 15 continues to rotate, the disengaged pawl 52 slides along the gentle slope 151 to the next tooth top under the action of horizontal thrust, and falls into the adjacent tooth groove 153 under the action of horizontal thrust. The entire movement process follows the change of "disengagement-slippage-engagement"; in this process, the continuous inclined structure of the gentle slope 151 decomposes the pulling force into a tangential sliding component and a radial impact force. Since the inner ends of each pawl 52 intersect and connect, while the outer ends are not connected to each other. This type of pawl shape will produce elastic deformation when subjected to force, so it can dissipate the radial impact force, thereby realizing the slipping function; since the pawl 52 cannot form an effective lock in the slipping state, the pulling force generated when pulling the wire can only cause the lower partition plate 12 and the ratchet transmission member 5 to rotate relative to each other, and is not transmitted to the sun gear 41 through the extension end 412. Therefore, it can be ensured that when pulling the wire, the winding mechanism is not interfered with by reverse operation.

[0055] Furthermore, to prevent the ratchet transmission member 5 from disengaging from the extension end 412 under sustained radial impact forces, which would affect the normal operation of the entire cable winder, the extension end 412 has at least one cut surface 413, forming a non-circular cross-section. The ratchet transmission member 5 has an anti-rotation hole 51 at its center, the inner contour of which aligns with the cut surface 413 to restrict relative rotation.

[0056] In a specific embodiment, the non-circular cross-section is, for example, D-shaped, polygonal, etc., so that the section 413 and the inner surface of the anti-rotation hole 51 form a tight fit, that is, the transmission gap is eliminated through the interference fit between the non-circular cross-section and the anti-rotation hole 51. (For example, a D-shaped cross-section and a D-shaped hole, a polygonal cross-section and a polygonal hole), this structural coordination forms a plurality of stop points at the connection between the anti-rotation hole 51 and the section 413. When the pawl 52 is subjected to a radial impact force, the stop point can effectively resist and prevent the pawl 52 from detaching from the extension end 412 due to the radial impact force. This design allows the pawl 52 to maintain a stable slipping effect when subjected to a horizontal thrust, thereby increasing the stability of the entire winder during operation.

[0057] In addition, when the ring gear 43 is rotated manually clockwise (from right to left), the planetary gear 42 drives the sun gear 41 to rotate counterclockwise (from left to right), and the sun gear 41 drives the ratchet transmission member 5 to rotate synchronously through the extended end 412 at the top of the central axis 411; at this time, the pawl 52 slides into the tooth groove 153 along the gently sloping surface 151 of the serrated portion 15, and is stuck under the limit of the vertical surface 152, so that the driving force is completely transmitted to the lower partition plate 12 through the engagement of the ratchet transmission member 5 and the serrated portion 15, driving it to rotate as a whole, thereby realizing stable winding of the wire cavity 13, and at the same time, the one-way locking characteristics formed by the cooperation of the ratchet transmission member 5 and the serrated portion 15 ensure that there is no slippage during the transmission process.

[0058] In summary, the first aspect of the wire winder provided by the present technical solution is to drive the fixed ring gear 43 in the lower shell 2 to rotate by utilizing the rotary connection part 3 formed by the boss 32 and the groove between the lower shell 2 and the upper shell 1, and the winding speed-increasing effect is achieved by the three-stage transmission of the ring gear 43, the planetary gear 42, and the sun gear 41, thereby converting manual rotation into efficient winding. Secondly, by coordinating the space enclosed by the upper and lower partition plates 12 in the wire cavity 13 with the ratchet transmission member 5, and by the one-way engagement of the pawl 52 with the serrated portion 15 (the gentle slope surface 151 and the vertical surface 152), the pawl 52 is caused to slip and idle along the gentle slope surface 151 when the wire is pulled, thereby cutting off the transmission path of the pulling force to the sun gear 41 and preventing reversal. Therefore, the present technical solution enables the entire wire winder to have good transmission stability through the cooperation of the planetary gear assembly 4 and the ratchet transmission member 5, and comprehensively solves the problems of convenience, winding efficiency and storage flatness of the wire winder in the prior art.
