Description

Wire winding device

Technical Field

The present disclosure relates to wire winding apparatuses, and particularly to a wire winding apparatus with a guiding structure.

Background

First, for 3C products, the product size is toward light, thin, short, and the signal transmission quality is inevitably increased. Taking the mobile adaptor as an example, when the product volume is reduced, the wire-winding space is limited. The smaller winding space means that the smaller the winding diameter is, the larger the influence of the hardness and tension of the wire is upon winding. In addition, as the signal transmission requirement increases, the wire becomes thicker, so that the hardness and tension of the wire are improved, and the trend of smaller and smaller the product size requirement is contradicted.

Taking the mobile adaptor as an example, a common wire winding method is to wind the wire into a loop by rotating the upper cover. In the prior art, due to the limitation of the wire winding space, the friction between the wires is easy to rise due to the roughness and tension of the wires when the wires are wound for the second turn, so that the wire winding hand feeling is poor. Therefore, in the prior art, when the wire is stored, the wire is often wound only once, which causes a shortage of the wire length and causes considerable inconvenience to the user.

Therefore, by improving the structural design, the wire can still maintain lower friction and smooth winding hand feeling when being wound for more than one turn, and further, the longer wire length can be accommodated, so that the defect is overcome, and the wire winding device has become one of important problems to be solved in the field.

It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used primarily to distinguish one element from another element. In addition, the term "or" as used herein shall include any one or combination of more of the associated listed items as the case may be.

Examples

First, referring to fig. 1, an embodiment of the present invention provides a winding device Z, which is mainly applied to an expansion port device (Docking Station). The expansion port device is an external device specially designed for notebook computers, and can enable the notebook computers to be connected with interface devices (such as a power adapter, a network cable, a mouse, an external keyboard, a printer and an external display) in one-stop mode. The wire winding device Z comprises a base 1, a cover plate 2 and a limiting plate 3. The base 1 may include various ports (not shown), such as ase:Sub>A high-definition multimediase:Sub>A interface (HDMI), ase:Sub>A Display Port (DP), ase:Sub>A Video Graphics Array (VGA), an ethernet, universal serial buses (USB-C and USB-ase:Sub>A), and the like. The limiting plate 3 is disposed on the base 1 and forms a gap D with the platform 10. The cover plate 2 is movably limited in the gap D, and forms a containing space 20 with the base 1. Next, refer to fig. 4. The wire winding device Z further includes a transmission wire 4, and the transmission wire 4 is movably accommodated in the accommodating space 20.

Referring to fig. 4 and 5, the base 1 has a platform 10. Specifically, the platform 10 is centrally located on the base 1. The side of the platform 10 has a wire buckle 101. The number of the buttons 101 can be adjusted according to the structural requirement, and the embodiment uses 2 buttons 101 as an example, but the invention is not limited thereto. In addition, the wire buckle 101 is separated from the wire buckle 101 by a fixed distance, which can be changed according to the structural requirement, and the invention is not limited thereto. The side of the base 1 is also provided with a wire outlet 102. One end of the transmission line 4 is fixed to the base 1 through the outlet 102. When the transmission line 4 is movably disposed in the accommodating space 20, it is disposed on the base 1 around the platform 10 in a winding manner, as shown in fig. 4.

Referring to fig. 4 and 6, the cover plate 2 has an opening 24 and a first guiding portion 25. The transmission line 4 is taken in and out through the opening 24. The transmission line 4 surrounds the platform 10 to form a first coil portion 41 and a second coil portion 42, and at this time, the first guide portion 25 presses the first coil portion 41 into the buckle 101.

The cover plate 2 further comprises a top plane 21 and side walls 22. The side walls 22 are disposed along the edges of the top plane 21 and form openings 24. The opening 24 is communicated with the accommodating space 20, and is used for leading out the transmission line 4 arranged in the accommodating space 20 or leading the transmission line 4 arranged outside the accommodating space 20 to be wound. When the transmission line 4 is wound through the opening 24, the side wall 22 is used for guiding the transmission line 4, so that the transmission line 4 surrounds the platform 10 and is placed on the base 1 in a winding manner.

Specifically, as shown in fig. 6 and 7, the top surface 21 has a notch 23, and the side wall 22 has a first end 221 and a second end 222. The first end 221 is bent inward to form a bent portion 27, and the second end 222 is formed to form a second guiding portion 26. Further, the first end 221 is bent inward toward the notch 23 to form a bent portion 27. The first guide 25 is disposed below the top plane 21, so that when the cover plate 2 is rotated, the first guide 25 rotates around the platform 10. The first guide portion 25 is positioned between the first coil portion 41 (inner coil wire) and the second coil portion 42 (outer coil wire). When the transmission line 4 is wound through the opening 24, the second guiding portion 26 is used for guiding the transmission line 4, and the first guiding portion 25 presses the first coil portion 41 into the buckle 101. The notch 23 is located directly above the platform 10 when the cover plate 2 is disposed on the base 1. In the present invention, the first guiding portion 25 has a radius R of rotation centered on the center of the platform 10, and the radius R of rotation is greater than the distance L from the center of the platform 10 to the outer edge of the button 101. Thus, when the cover plate 2 is rotated to store the transmission line 4 in the storage space 20, the first guide portion 25 is not interfered by the wire buckle 101 during rotation.

The primary function of the first guide portion 25 is to fix the innermost wire wound in a loop in the coil 101 when the transmission line 4 is accommodated in the accommodating space 20, so as to prevent the inner wire from rubbing with the outer wire due to the outward tension. It should be noted that the present invention is not limited to the position and number of the first guiding portions 25, and the example of the present invention is only one possible embodiment and is not limited to the present invention. Without violating the design concept of the present invention, the user can simply change the position and number of the first guiding portions 25 according to the actual requirement, and all the equivalent technical changes achieved are included in the present invention.

Referring to fig. 1 and 4, the cover plate 2 is sandwiched between the limiting plate 3 and the base 1. The limiting plate 3 is disposed in the notch 23 and screwed to the platform 10 of the base 1. The top plane 21 of the cover plate 2 also has a recessed region 211, the recessed region 211 being adjacent and surrounding the slot 23. Therefore, when the limiting plate 3 is disposed in the notch 23, the outside of the limiting plate 3 covers the recessed area 211. Further, the height difference between the bottom of the recess 211 and the top plane 211 is equal to the thickness of the limiting plate 3, so that when the limiting plate 3 is disposed in the notch 23, the top surface of the limiting plate 3 is aligned with the top plane 21 of the cover plate 2.

Referring to fig. 2 and 3, the recess 211 of the cover plate 2 is located in the gap D, and the thickness of the recess 211 is smaller than the gap D. As described in the previous section, since the cover plate 2 is movably limited in the gap D, the cover plate 2 can be rotated to receive the transmission line 4 into the receiving space 20. In other words, the gap D is used to enable the cover plate 2 to rotate freely when sandwiched between the base 1 and the limiting plate 3.

Referring to fig. 1 and 4, the cover 2 drives the first guide portion 25 and the second guide portion 26 to store the transmission line 4 in the accommodating space 20 by rotating clockwise, and drives the first guide portion 25 and the second guide portion 26 to withdraw the transmission line 4 from the accommodating space 20 by rotating counterclockwise. When the cover plate 2 rotates clockwise to drive the first guide portion 25 and the second guide portion 26 to store the transmission line 4 in the accommodating space 20, the transmission line 4 is wound around the platform 10 and placed on the base 1, and the transmission line 4 forms a first coil portion 41 and a second coil portion 42 around the platform 10. The first coil portion 41 is located inside and adjacent to the platform 10, so that the wire buckle 101 on the side of the platform 10 fixes the first coil portion 41. In addition, at this time, the first guide portion 25 is provided between the first coil portion 41 and the second coil portion 42, reducing the contact area between the first coil portion 41 and the second coil portion 42, that is, reducing the friction between the wires (transmission lines) when the transmission line 4 is wound.

In this embodiment, the first guide portion 25 and the second guide portion 26 have a columnar structure. However, the present invention is not limited thereto, and in other embodiments, the first guiding portion 25 and the second guiding portion 26 can be roller structures floating on the cover 2.

The transmission line 4 includes a transmission line head 40 having a snap-fit portion 401. When the cover plate 2 rotates clockwise to drive the first guiding portion 25 to store the transmission line 4 in the accommodating space 20, the transmission line 4 is placed on the base 1 around the platform 10 in a winding manner, and the transmission line head 40 is fastened and fixed on the second guiding portion 26 through the fastening portion 401. In this embodiment, the fastening portion 401 is a protruding structure. However, the present invention is not limited thereto, and in other embodiments, the fastening portion 401 may be a groove structure or other fastening structures corresponding to the shape of the second guiding portion 26.

Referring to fig. 7 to 9, the winding operation of the winding device Z provided by the present invention is further described. First, as shown in fig. 7, fig. 7 shows a state that the transmission line 4 completely exits from the accommodating space 20, and the extension direction of the transmission line 4 is that the transmission line passes through between the first guiding portion 25 and the second guiding portion 26 after exiting from the outlet 102, and the first guiding portion 25 is located relatively inside the transmission line 4.

Next, as shown in fig. 8, when the user wants to collect the transmission line 4 into the wire collecting device Z, the user rotates the cover plate 2 clockwise one turn to collect the transmission line 4 into the accommodating space 20, so as to form the first coil portion 41. Since the first guide portion 25 is disposed on the cover 2, the first guide portion 25 rotates when the cover 2 rotates. In other words, the first guide portion 25 returns to the position substantially similar to fig. 7 after one rotation.

Next, as shown in fig. 7 and 8, after the first winding (forming the first coil portion 41) is completed, the cover 2 continues to rotate clockwise, and the first guide portion 25 sequentially presses the first coil portion 41 of the transmission line 4 into the button 101 to fix the first coil portion 41, and the winding is continuously performed, where the first guide portion 25 is located between two turns of the transmission line 4. The first coil portion 41 needs to be fixed by the wire button 101 in order to prevent the transmission wire 4 wound into a loop from having an excessively large area contact with the subsequently formed second coil portion 42 due to the wire tension thereof, so that friction is generated between the first coil portion 41 and the second coil portion 42, thereby interfering with the subsequent winding operation.

As shown in fig. 8 and 9, the cover plate 2 is continuously rotated, the first coil portion 41 is pressed into the wire button 101, and the second coil portion 42 of the transmission wire 4 is also accommodated in the accommodating space 20, so that the second winding (forming the second coil portion 42) is completed, and the engaging portion 401 of the transmission wire head 40 is engaged with the second guide portion 26, so that the winding operation (forming the first coil portion 41 and the second coil portion 42) is completed, as shown in fig. 9. The bending direction of the bending portion 27 can press the portion of the transmission line 4 close to the transmission line head 40 inwards, so that the platform 10 is ensured to have a large enough area for the transmission line head 40 to be placed.

Referring to fig. 10, the wire-out action of the wire-rewinding device Z provided by the present invention is further described. When the user wants to withdraw the transmission line 4, the cover 2 can be rotated counterclockwise, and the first guiding portion 25 pushes the transmission line 4 out of the wire buckle 101 (as shown by arrow a in fig. 10) until the transmission line 4 completely withdraws from the accommodating space 20, thereby completing the wire-withdrawing operation.

Advantageous effects of the embodiments

The wire winding device Z provided by the invention has the beneficial effects that the wire winding device Z can be used for winding and outgoing wires through the technical scheme that the wire winding device Z comprises a base 1, a cover plate 2 and a transmission wire 4, the base 1 is provided with a platform 10, the side edge of the platform 10 is provided with a wire buckle 101, a limiting plate 3 is arranged on the base 1 and forms a gap D with the platform 10, the cover plate 2 is movably limited in the gap D and forms a containing space 20' with the base 1, and the transmission wire 4 can be wound and outgoing wires through an opening 24, when the transmission wire 4 surrounds the platform 10 to form a first coil part 41 and a second coil part 42, the first guide part 25 presses the first coil part 41 into at least one wire buckle 101", and friction force between wires is reduced through the design of a guide structure (the first guide part 25) so as to improve the wire winding feel.

Furthermore, the transmission line 4 is pressed into the buckle 101 by the guide structure (the first guide portion 25) during winding, and the inner coil (the first coil portion 41) and the outer coil (the second coil portion 42) are separated by the guide structure, so that the first coil portion 41 is prevented from contacting the second coil portion 42 due to the tension of the wire, and the subsequent winding operation is prevented from being influenced by excessive friction. The structural design of the guide structure of the invention improves the defect that only one circle of wire can be accommodated in the prior art, and can still maintain lower friction and smooth wire-receiving hand feeling when the wire is allowed to be wound for more than one circle under smaller volume, so that the length of the wire can be prolonged in the design of the product, and the effects of reducing the volume of the product and not influencing the accommodating length of the wire are achieved.

The foregoing disclosure is only a preferred embodiment of the present invention and is not intended to limit the scope of the claims, so that all equivalent technical changes made by the application of the present invention and the accompanying drawings are included in the scope of the claims.
