[0026] Among them, when winding the cable into the wire winding housing, first, the rotating ring rotates under the driving action of the second driving mechanism. At the same time, since a part in the middle of the cable is fixedly connected to the top of the wire winding groove, the cable will not be driven to rotate by the wire feeding cylinder. Moreover, when the cable comes out of the wire feeding cylinder, the height of the winding shaft also increases, so that the cable can be continuously wound in the wire winding groove, thus realizing the winding of the cable, which is simple and convenient.

[0056] The first driving mechanism includes a linkage cylinder 15 vertically arranged at the bottom of the rotating ring 5. A plurality of lifting balls 16 are rotatably arranged on the inner wall of the linkage cylinder 15. Each lifting ball 16 is movably attached to the inner wall of the wire winding groove 4. When the wire feeding cylinder 6 introduces wire into the wire winding groove 4, the winding shaft 3 rises;

[0057] An anti-rotation column 17 is vertically arranged at the top of the wire winding housing 1.

There is an arc transition between the stabilizing part 6c and the transition part 6a. A relief opening 19 is formed on the linkage cylinder 15. The top of the stabilizing part 6c and the bottom of the transition part 6a are both located in the relief opening 19. The bottom of the stabilizing part 6c is lower than the winding shaft 3.

[0059] A stabilizing plate 20 is horizontally arranged on the inner wall of the wire take-up housing 1. A stabilizing hole 21 is vertically penetrated through the stabilizing plate 20, and the stabilizing part 6c movably passes through the stabilizing hole 21. An auxiliary plate 22 is also horizontally arranged on the inner wall of the wire take-up housing 1. The auxiliary plate 22 is located below the stabilizing plate 20. The power shaft 13 vertically penetrates through the stabilizing plate 20, the auxiliary plate 22 and the two second support plates 8, and is respectively rotatably connected to the stabilizing plate 20, the auxiliary plate 22 and the two second support plates 8;

[0060] An auxiliary hole 23 for the cable to pass through is vertically penetrated through the auxiliary plate 22. The auxiliary hole 23 is located above the cable inlet 2. A first support frame 24 and a second support frame 25 are arranged at the bottom of the auxiliary plate 22. A driving auxiliary wheel 26 is vertically rotatably arranged on the first support frame 24. A driven auxiliary wheel 27 is vertically rotatably arranged on the second support frame 25. Auxiliary grooves 28 are formed on the outer walls of both the driving auxiliary wheel 26 and the driven auxiliary wheel 27. Both sides of the cable are attached to the inner walls of the auxiliary grooves 28;

[0061] A transmission mechanism is arranged between the bottom of the power shaft 13 and the driving auxiliary wheel 26. The power shaft 13 drives the driving auxiliary wheel 26 to rotate upwardly by the transmission mechanism in a manner that it fits against one side of the cable.

[0062] The transmission mechanism includes a first transmission column 29, a second transmission column 30, a third transmission column 31 and a fourth transmission column 32 which are vertically rotatably arranged at the bottom of the auxiliary plate 22. The first transmission column 29 is fixedly connected to the power shaft 13. A first transmission member 33 is arranged between the first transmission column 29 and the second transmission column 30. A second transmission member 34 is arranged between the second transmission column 30 and the third transmission column 31. A set distance is provided between the first transmission member 33 and the second transmission member 34. The first transmission member 33 is movably sleeved on the first transmission column 29 and the second transmission column 30. The second transmission member 34 is movably sleeved on the second transmission column 30 and the third transmission column 31;

[0063] An upward-facing first bevel gear 35 is arranged on the third transmission column 31. A downward-facing second bevel gear 36 which meshes with the first bevel gear 35 is arranged on the fourth transmission column 32. A support rod 37 is horizontally arranged in the middle of the driving auxiliary wheel 26. The support rod 37 is rotatably connected to the first support frame 24. A third bevel gear 38 which meshes with the second bevel gear 36 is vertically arranged at the end of the support rod 37. A barrier ring 39 is arranged on the outer wall in the middle of the second transmission column 30. The first transmission member 33 and the second transmission member 34 are located on both sides of the barrier ring 39.

[0064] The thickness of the driving gear 14 is less than that of the rotating ring 5, and there is a set gap between the driving gear 14 and both the first thrust bearing 9 and the second thrust bearing 10;

[0065] On one side of the second support plate 8 close to the driving gear 14, stabilizing cylinders 40 are provided. The power shaft 13 passes through the two stabilizing cylinders 40. At the ends of the stabilizing cylinders 40, stabilizing balls 41 are rotatably provided, and the stabilizing balls 41 are movably abutted against the upper and lower sides of the driving gear 14.

[0066] A limiting cylinder 42 is vertically provided at the top of the wire winding housing 1. At the bottom of the limiting cylinder 42, a limiting portion 43 with a downward-opening trumpet shape is provided. The outer wall of the wire cable wound in the wire winding groove 4 is movably attached to the inner wall of the limiting cylinder 42. A long strip-shaped moving hole 44 is vertically opened on the side of the limiting cylinder 42, and the wire cable movably passes through the moving hole 44.

[0067] After the wire cable is used, it is necessary to wind the wire cable into the wire winding housing 1, so as to ensure the cleanliness of the wire cable, and at the same time, the amount of exposure to wind, sun, etc. can be reduced, and its service life can be extended.

[0068] When winding the cable into the wire winding housing 1, first, the rotating ring 5 rotates under the driving action of the second driving mechanism. At the same time, since one part of the middle of the wire cable is fixedly connected to the top of the wire winding groove, the wire cable will not be driven to rotate by the wire paying-off cylinder 6. Moreover, when the wire cable comes out of the wire paying-off cylinder 6, the height of the winding shaft 3 also increases, so that the wire cable can be continuously wound in the wire winding groove 4, thus realizing the winding of the wire cable, which is simple and convenient.

[0069] When winding the wire cable, first, the driving motor 12 receives a signal and drives the power shaft 13 to rotate. At the same time, the power shaft 13 drives the driving gear 14 to rotate, and the driving gear 14 drives the rotating ring 5 and the wire paying-off cylinder 6 to rotate through the driven gear 11. Moreover, the linkage cylinder 15 at the bottom of the power ring is also driven to rotate. The anti-rotation sleeve 18 in the middle of the winding shaft is limited by the anti-rotation column 17, so the winding shaft cannot rotate. However, since the lifting balls 16 on the inner wall of the linkage cylinder 15 can act on the inner wall of the wire winding groove 4 (with a relatively large diameter, approximately equal to the diameter of the wire cable), the lifting balls 16 can drive the winding shaft 3 to rise;

[0070] That is, during actual wire winding, only one power of the driving motor 12 is needed to drive the rotating ring 5 to rotate and at the same time drive the winding shaft 3 to rise. Moreover, by designing corresponding dimensions, the speed of the wire cable released from the wire paying-off cylinder 6 can be made equal to the speed of the wire cable wound on the winding shaft 3, so that the wire cable can be stably received;

[0071] Moreover, during the rotation of the power shaft 13, the first transmission column 29 is also driven to rotate; the first transmission column 29 drives the second transmission column 30 to rotate through the first transmission member 33, and the second transmission column 30 drives the third transmission column 31 to rotate through the second transmission member 34; the first bevel gear 35 on the third transmission column 31 can drive the second bevel gear 36 on the fourth transmission column 32 to rotate; finally, the second bevel gear 36 drives the active auxiliary wheel 26 to rotate through the third bevel gear 38 and the support rod 37, and the active auxiliary wheel 26 and the driven auxiliary wheel 27 are pressed against both sides of the cable, so the driven auxiliary wheel 27 can be driven by the cable to rotate.

[0072] Among them, during the process of winding the cable, taking Figure 6 、 9 and 16 as examples, at this time, the power shaft 13 can drive the sides of the active auxiliary wheel 26 and the driven auxiliary wheel 27 close to the cable to drive upward through the transmission mechanism, so it is convenient to wind the cable into the wire winding case 1; and because the active auxiliary wheel 26 and the driven auxiliary wheel 27 can play a role in limiting and guiding the cable, it can better prevent the cable from moving too much, ensuring the movement stability of the cable;

[0073] Similarly, by designing the dimensions of each structure (including but not limited to the first transmission column 29, the second transmission column 30, the third transmission column 31, the diameter of the third transmission column 31, the first bevel gear 35, the second bevel gear 36 and the diameter of the third bevel gear 38), the speed of the cable passed by the active auxiliary wheel 26 and the driven auxiliary wheel 27 can be made equal to the winding speed of the wire winding groove 4 and also equal to the cable releasing speed of the cable feeding cylinder 6. At the same time, since the cable is limited by the active auxiliary wheel 26 and the driven auxiliary wheel 27 before entering the cable feeding cylinder 6, the cable tension during the cable feeding cylinder 6 pulling the cable can be ensured, ensuring the winding quality.

[0074] Among them, when charging by pulling the cable outwards, the drive motor 12 rotates in the reverse direction at this time, and the winding shaft 3 moves downward under the action of the linkage cylinder 15. At this time, the cable cannot enter the cable feeding cylinder 6 well actively (unless the cable is pulled externally); but at this time, both the active auxiliary wheel 26 and the driven auxiliary wheel 27 can apply a downward force (static friction force) to the cable, so that the cable can be actively pulled downward. Without the user pulling the cable externally, the cable can also enter and pass through the cable feeding cylinder 6 well, and the use effect is better.

[0075] The first transmission member 33 and the second transmission member 34 in this application are preferably one of a belt, a V-belt, an internal gear belt, or a chain, and the first transmission column 29, the second transmission column 30, and the third transmission column 31 are structures that cooperate with the first transmission member 33 and / or the second transmission member 34; at the same time, since there is a barrier ring 39 between the first transmission member 33 and the second transmission member 34, during actual use, it can effectively prevent wear between the first transmission member 33 and the second transmission member 34, extending the service life.

[0076] The first support plate 7 and the second support plate 8 support the first thrust bearing 9 and the second thrust bearing 10. Therefore, it first ensures the position stability of the first thrust bearing 9 and the second thrust bearing 10, so that the position of the rotating ring 5 can be supported; at the same time, while the first thrust bearing 9 and the second thrust bearing 10 can well bear the gravity and pressure of the rotating ring 5, they can also well bear the acting forces of the winding shaft 3 and the cable, ensuring the service life.

[0077] There is a stabilizing cylinder 40 on the second support plate 8, and the stabilizing cylinder 40 abuts against the upper and lower sides of the power gear through stabilizing balls 41. Therefore, during actual use, it can also ensure and improve the use stability and shape stability of the power gear. Moreover, since the thickness of the power gear is less than the thickness of the rotating ring 5, and the power gear does not contact the first thrust bearing 9 and the second thrust bearing 10, wear between the two is prevented, ensuring the service life. Herein, the "set interval", "set spacing", or similar descriptions in this application all indicate that two structures are in a non-contact state, and the actual spacing size can be adjusted or changed according to the actual situation.

[0078] During use, the length of the power shaft 13 is relatively long. Therefore, it is not only rotatably connected to two second support plates 8 at the same time, but also rotatably connected to the stabilizing plate 20 and the auxiliary plate 22, so that the shape stability of the power shaft 13 can be further improved or ensured; secondly, the stabilizing hole 21 opened on the stabilizing plate 20 can play a role in limiting the cable, preventing some cables from being wound or acting on the bottom of the winding shaft 3 during use, ensuring the winding stability.

[0079] The top of the wire feeding cylinder 6 is a guiding portion 6b with a radian of π / 4, and the top of the guiding portion 6b is directly facing the wire receiving groove 4. Moreover, no matter which angle the rotating ring 5 rotates to, the guiding portion 6b is continuously directly facing the wire receiving groove 4, so that the guiding effect of the cable is better. Secondly, the transition portion 6a is arc-shaped, facilitating the transition of the cable out of the wire feeding cylinder 6 and being better pulled out from the wire feeding cylinder 6. And the stabilizing portion 6c is in a vertical state, and its bottom is lower than the winding shaft 3. Therefore, during the winding process, it can further prevent the cable from being wound around the bottom of the winding shaft 3.

[0080] After the cable is wound around the cable storage groove 4, the cable rises with the cable storage groove and then immediately enters the limiting cylinder 42 through the transition of the limiting portion 43. The horn-shaped limiting portion 43 makes it easier for the cable to enter the limiting cylinder 42. Since the winding shaft 3 around which the cable is wound moves vertically up and down, and the outer wall of the cable is limited by the inner wall of the limiting cylinder 42, during the actual cable winding process, the limiting cylinder 42 can well maintain the stability of the connection between the cable and the winding shaft 3, and no wire-off or loosening will occur, ensuring the cable winding effect.

[0081] The middle part of the cable is fixedly connected to the top of the cable storage groove 4. At the same time, the winding shaft 3 moves up and down. Therefore, a part of the cable is movable, and this part of the movable cable passes through the movable hole 44. At this time, even if the height of the winding shaft 3 changes, this part of the cable can still be in an energized state with the cable at the fixed connection part of the winding shaft 3.

[0082] In the present invention, unless otherwise clearly specified and defined, for example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.
