[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] The cable retracting device according to an embodiment of the present invention comprises: a cable and a cable retracting assembly 1, wherein the cable retracting assembly 1 comprises a mounting bracket 11, a driving component 12 and a reel 13, wherein the reel 13 and the driving component 12 are arranged on the mounting bracket 11, and the driving component 12 drives the reel 13 to rotate to collect or release the cable;

[0031] A guide assembly 2 is arranged on the mounting bracket 11, and the guide assembly 2 includes a moving component 22 and a guide component 21 connected to the mounting bracket 11. The cable is suitable for passing through the guide component 21 and being wound on the reel 13.

[0032] The cable is wound around the outer circumference of the guide component 21 , and the moving component 22 drives the guide component 21 to move in the width direction of the mounting bracket 11 to guide the cable.

[0033] The cable retracting and releasing device of the embodiment of the present invention can guide the cables when they are retracted and released, thereby preventing the cables from being stacked.

[0034] Specifically, Figures 1 to 4 As shown, the cable retracting assembly 1 is suitable for collecting or releasing cables, and the cable retracting assembly 1 comprises a mounting bracket 11, a driving component 12 and a reel 13. The reel 13 extends in the left-right direction.

[0035] The reel 13 rotates to collect or release the cable, and the driving component 12 drives the reel 13 to rotate. For example, the driving component 12 drives the reel 13 to rotate forward to collect the cable, and the driving component 12 drives the reel 13 to reverse to release the cable, and the reel 13 is rotatably arranged on the mounting bracket 11, and the guide assembly 2 is arranged on the mounting bracket 11. The moving component 22 moves the guide assembly 21 in the left and right direction, so that the cable is evenly wound on the reel 13 during collection or release. The cable is suitable for passing through the guide assembly 2 to be wound on the reel 13. Through the movement of the guide assembly 2 in the left and right direction, the cable can be evenly wound on the reel 13 in the left and right direction, thereby avoiding the cable from being stacked on the reel 13, and avoiding the cable from being deformed by hard pulling due to excessive or insufficient release of the cable.

[0036] The cable retracting device of the embodiment of the present invention is provided with a guide component 21 and a movable component 22. The movable component 22 enables the guide component 21 to move in the left-right direction, so as to guide the cable when the reel 13 is retracted and released, thereby avoiding the cable from being stacked, thereby avoiding the cable from being deformed by hard pulling due to excessive or insufficient release of the cable, and improving the stability and service life of the device.

[0037] In some embodiments, the guide component 21 includes a mounting seat 211, a first vertical wheel 212, a second vertical wheel 213 and a first horizontal wheel 214. The first vertical wheel 212 and the second vertical wheel 213 are rotatably disposed on the mounting seat 211. The first horizontal wheel 214 is disposed between the first vertical wheel 212 and the second vertical wheel 213 arranged at intervals along the width direction of the mounting bracket 11. The first horizontal wheel 214 is rotatably disposed on the mounting bracket 11.

[0038] In the process of collecting or releasing the cables, the cables come into contact with the first vertical wheel 212 , the second vertical wheel 213 and the first horizontal wheel 214 .

[0039] Specifically, Figures 1 to 4 As shown, the moving component 22 enables the guide component 21 to move in the left-right direction. The lower end of the moving component 22 is connected to the mounting seat 211. The moving component 22 drives the mounting seat 211 to move in the left-right direction. The moving component 22 is arranged at intervals on the mounting seat 211. The moving component 22 can be an existing moving component 22, a moving device or a moving member 221, or the moving component 22 can be an existing linear guide rail. The first horizontal wheel 214 extends in the left-right direction, the first vertical wheel 212 and the second vertical wheel 213 extend in the up-down direction, the cable is mounted on the first horizontal wheel 214, and the cable is mounted on the first horizontal wheel 214 under the guidance of gravity.

[0040] During the cable collection and release process, the cable is laid on the first horizontal wheel 214, and the outer circumference of the cable is in contact with the second vertical wheel 213 and the first vertical wheel 212, thereby guiding and limiting the movement of the cable in the up and down and left and right directions to prevent the cable from being concentrated in a partial area of ​​the reel 13. The first horizontal wheel 214 and the first vertical wheel 212 and the second vertical wheel 213 are rotatable relative to the mounting seat 211, that is, they rotate as the cable is retracted and released, so as to reduce the resistance of the cable when it is collected or released.

[0041] In some embodiments, the cable retracting device further includes a second transverse wheel 215 disposed on the mounting seat 211 , and the second transverse wheel 215 and the first transverse wheel 214 are spaced apart in the height direction of the mounting bracket 11 .

[0042] Specifically, Figures 1 to 4 As shown, the second horizontal wheel 215 extends in the left-right direction, the second horizontal wheel 215 is parallel to the first horizontal wheel 214 in the up-down direction, and the first horizontal wheel 214 and the second horizontal wheel 215 are arranged at intervals in the up-down direction, thereby limiting and guiding the up-down direction of the cable output and input, and the first horizontal wheel 214 and the second horizontal wheel 215 cooperate with the first vertical wheel 212 and the second vertical wheel 213 to guide the cable in the left-right direction and the up-down direction. Avoid the cable from deviating from the preset moving path during use, and improve the stability and safety of cable collection.

[0043] In some embodiments, the driving component 12 includes a first turn counting component and a driving member 122 . The output end of the driving member 122 is provided with the first turn counting component, and the output end of the driving member 122 is connected to the reel 13 .

[0044] Specifically, Figures 1 to 4 As shown, the driving member 122 is connected to the reel 13 to drive the reel 13 to rotate, and the first revolution counting component is arranged at the output end of the driving member 122 to monitor the revolution of the driving member 122 to determine the revolution of the reel 13.

[0045] In some embodiments, the radial dimension of the cable is 65 to 72 mm. For example, ideally, each time the drum 13 rotates one circle, the guide member 21 should move laterally in the left-right direction by a distance equal to the cable pitch. However, due to differences in cable diameters, the actual moving distance may have a certain error from the theoretical value. In order to obtain the best winding or discharge effect and reduce the adverse effects of such errors, the radial dimension of the cable is set between 65 mm and 72 mm. At the same time, it also prevents the cable from being stuck on the first vertical wheel 212 and the second vertical wheel 213 due to the cable being too thick.

[0046] In some embodiments, the moving component 22 includes a controller, a moving member 221 and a distance monitoring member. One end of the moving member 221 is connected to the mounting seat 211 so that the mounting seat 211 moves in the width direction of the mounting bracket 11. The distance monitoring member is suitable for monitoring the moving distance of the mounting bracket 11.

[0047] The controller is connected to the first turn counting component, the moving member 221 and the distance monitoring component respectively, so as to control the moving member 221 through the data monitored by the first turn counting component so that the mounting seat 211 moves a preset distance in the width direction of the mounting bracket 11. The controller controls the action of the moving member 22 according to the data provided by the first turn counting component (i.e., the number of turns of the drum 13), thereby ensuring that the mounting seat 211 can accurately move a preset distance in the width direction of the mounting bracket 11. This design can make the winding or discharge process of the cable more accurate and efficient. For example, the controller determines the number of turns of the drum 13 according to the number of turns of the output end of the driving member 122 provided by the first turn counting component, so as to control the moving distance of the moving member 22 in the front-to-back direction, i.e., theoretically, for every turn of the drum 13, the guide member 21 moves a cable pitch laterally in the left-right direction.

[0048] In some embodiments, the cable retracting device further comprises a protective cover 3 disposed on the top of the mounting bracket 11. The protective cover 3 can prevent dust or components from interfering with the cable on the reel 13.

[0049] In some embodiments, Figure 3 As shown, the first transverse wheel 214 and the second transverse wheel 215 both have a groove 216 sunken toward the axis, so that the outer circumference of the cable can better match the first transverse wheel 214 or the second transverse wheel 215, increase the contact area, and improve the guiding and limiting effects.

[0050] In some embodiments, the moving member 221 is a linear guide rail. The mounting seat 211 can achieve smooth and precise linear movement along the linear guide rail in the width direction of the mounting bracket 11. Through the use of the linear guide rail, the stability of the movement of the mounting seat 211 can be greatly improved, thereby ensuring high-quality completion of the cable winding or discharge operation.
