Description
Technical Field
[0001] The present invention relates to the technical field of robot-assisted instruments, and in particular to a wiring harness device for retracting and releasing a robot charging cable. Background Art
[0002] The robot charging cable is a power transmission accessory designed specifically for various types of automated equipment and service robots. It features excellent flexibility, pull resistance, and abrasion resistance, ensuring stable power supply even under complex operating conditions such as frequent bending and movement. Compared to traditional charging cables, it is more compact, more adaptable, and supports quick plug-and-disconnect connections, significantly improving charging efficiency.
[0003] To meet the need for efficient management of robot charging cables, charging cable retraction and release devices have emerged. These devices are widely used in intelligent equipment such as industrial robots, AGVs (automated guided vehicles), and robot vacuums, serving as a crucial component for ensuring efficient and safe operation.
[0004] However, the current common wiring harness devices still have many shortcomings in actual use. Due to its relatively simple internal structure, it is often necessary to directly pull the end of the charging cable to achieve unfolding during operation. This operation method brings the following problems: First, frequent pulling will cause the end of the charging cable to be directly stressed, resulting in retraction due to friction, which in turn causes the cable body to stretch and deform, shortening its service life; secondly, during the manual retraction process, it is difficult to accurately control the required length of the charging cable, resulting in the charging cable being too long and sagging, which not only affects the overall layout appearance, but may also cause the interface to loosen due to accidental pulling, affecting charging stability and even causing damage to the equipment. Therefore, there is an urgent need to develop a wiring harness device for robot charging cable retraction, which can improve the convenience, safety and durability of the charging cable retraction process while ensuring power transmission performance.

DETAILED DESCRIPTION
[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0030] Example: A harness device for retracting and releasing a robot charging cable, such as Figures 1-8 As shown, including: The housing 1 has a roller 11 rotating between the left and right sides of the housing 1; Solid component 2, which includes a sleeve 21 wound around the winding roller 11. The end of the sleeve 21 closest to the robot slides out of the right end of the winding roller 11, while the other end of the sleeve 21 passes through the lower portion of the housing 1. The interior of the sleeve 21 is provided with the charging cable body 100, as well as traction ropes 24 on the left and right sides for fixing the charging cable body 100. To reduce the pulling damage to the charging cable body 100 during the retraction process, a special sleeve 21 is configured to place the charging cable body 100 inside to form a protective barrier, and both ends of the sleeve 21 are exposed to the device to ensure that both ends of the charging cable body 100 are extended synchronously for subsequent connection and use; in addition, the provision of the traction rope 24 can enhance the overall structural stability of the sleeve 21, thereby further strengthening the protection of the charging cable body 100 and effectively avoiding deformation or damage caused by external forces.
[0031] The winding assembly 3 includes a mounting frame 31 fixedly arranged on the left side of the outer shell 1, and a driving motor 32 is installed on the mounting frame 31. A movable plate 33 slides on the output shaft of the driving motor 32. An end face ratchet 1 34 is provided on the side of the movable plate 33 facing the outer shell 1, and an end face ratchet 2 35 meshing with the end face ratchet 1 34 is provided on the end of the winding roller 11. A reset copper sheet 36 for limiting the position of the movable plate 33 is also provided around the mounting frame 31.
[0032] In order to achieve rapid switching between automatic retraction and manual adjustment, the drive motor 32 drives the end ratchet 1 34 to move, so that it forms an intermittent meshing transmission relationship with the end ratchet 2 35, thereby realizing automatic control of the reeling process; when manual fine-tuning is required, the brief disengagement between the end ratchet 1 34 and the end ratchet 2 35 can provide the necessary operating space, allowing the operator to flexibly adjust the effective use length of the charging cable body 100, effectively solving the problem of difficult adjustment of the charging cable length in the traditional structure, and avoiding situations such as the cable being too short or too long to droop due to length mismatch, thereby realizing rapid and precise control of the retraction and release of the charging cable body 100.
[0033] like Figure 2 and Figure 4 As shown, it also includes a support plate 12 circumferentially arranged at the right end of the winding roller 11. The support plates 12 are hinged with a triangular plate 13 that contacts and abuts against the sleeve 21. The corner of the support plate 12 facing the inside of the shell 1 is a right-angle end 122, and the right-angle end 122 abuts against the corresponding triangular plate 13. The corner of the support plate 12 facing the outside of the shell 1 is a rounded end 121, and the rounded end 121 contacts and cooperates with the corresponding triangular plate 13. The design of the right-angle end 122 and the rounded end 121 on the support plate 12 ensures that the charging cable body 100 can only be extended toward the outside, limits the overall extension direction of the charging cable body 100, and effectively avoids the cable retreat or deviation caused by improper operation or external force, so as to improve the accuracy and safety of wiring.
[0034] like Figure 2 and Figure 4-Figure 6 As shown, it also includes rings 22 respectively arranged at the head and tail ends of the sleeve 21. The diameter of the ring 22 is smaller than the diameter of the sleeve 21, and a cable tie 23 is provided at the end of the ring 22 for fixing the position between the sleeve 21 and the charging cable body 100.
[0035] Furthermore, the design of the ring 22 enables it to be tightly wrapped around the charging cable body 100. Due to the small diameter advantage of the ring 22 itself, the ring 22 can provide additional clamping force to ensure that the sleeve 21 is firmly attached to the charging cable body 100, thereby preventing slippage or separation between the two. In addition, the use of the cable tie 23 can further enhance the stability of the connection point, effectively preventing the charging cable body 100 from being displaced or loosened due to external pulling or internal stress, providing an additional layer of physical protection, and reducing the risk of wear and damage.
[0036] like Figure 1 and Figure 2As shown, it also includes an extension plate 4 symmetrically arranged at the bottom of the shell 1, and a clamping plate 41 is hinged symmetrically between the extension plates 4. The clamping plate 41 is provided with an interlocking opening 411 that is interlocked with the sleeve 21 to ensure that the sleeve 21 can be accurately positioned and fixed in a predetermined position, preventing it from being unnecessary displaced or loosened during the process of retraction and use, thereby improving the overall stability. A push plate 42 that contacts and cooperates with the clamping plate 41 slides between the extension plates 4 on both sides. It can be seen that by pressing down the push plate 42, the clamping plates 41 on both sides can be forced to close, providing physical limits for the sleeve 21 and the charging cable body 100 below, providing necessary guidance during the process of retracting and releasing the cable, and avoiding unnecessary bending. In addition, this design can also effectively limit and protect the connector at the tail end of the charging cable body 100 to prevent damage.
[0037] like Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, it also includes a protective cover 5 hinged on the front and rear sides of the shell 1. The protective cover 5 is adapted to the shape of the shell 1. The protective covers 5 on both sides are fitted together and a connecting opening is opened between the two to extend the sleeve 21 and the charging cable body 100 passing through the shell 1, and the fitting parts of the protective covers 5 on both sides are also provided with connecting guide grooves 51. A buckle plate 52 is sliding between the two connected guide grooves 51 to fix the position of the protective covers 5 on both sides after closing. By pushing the buckle plate 52 to change the position between the guide grooves 51, the effect of opening and closing the protective covers 5 on both sides is achieved.
[0038] like Figure 10 As shown, the protective cover 5 further includes auxiliary rollers 53 respectively provided on the inner walls of the protective cover 5 on both sides, and the sleeve 21 is located between the auxiliary rollers 53 on both sides.
[0039] like Figure 1 、 Figure 2 、 Figure 9 and Figure 11 As shown, it also includes a mounting assembly 6, which includes a groove ring 61 arranged on the right side of the shell 1. The groove ring 61 is arranged opposite to the mounting frame 31, and a rotating ring 62 is rotated on the groove ring 61. The rotating ring 62 is hinged with an assembly plate 63. Through the rotation cooperation between the groove ring 61 and the rotating ring 62, the assembly plate 63 can be flexibly adjusted in multiple directions, so as to be adjusted to a suitable installation angle according to actual usage requirements.
[0040] like Figure 9 and Figure 11As shown, the mounting assembly 6 also includes a clamping block 621 that is circumferentially slidably embedded in the interior of the rotating ring 62. The clamping block 621 is clamped and fitted with the groove ring 61, and an elastic member 622 is provided between the clamping block 621 and the inner wall of the rotating ring 62. In this embodiment, the elastic member 622 is a spring. Through the clamping fit between the clamping block 621 and the groove ring 61, combined with the elastic force provided by the elastic member 622, it can ensure that the rotating ring 62 is firmly fixed at the selected angular position, and effectively avoid position displacement caused by external force or vibration. The rotating ring 62 is provided with a plug rod 623 that is plugged into the assembly plate 63, so that when the assembly plate 63 is not enabled, the position locking can be achieved by the plug rod 623 to maintain the stability and compactness of the overall structure.
[0041] Before using this device, first ensure that the two ends of the charging cable body 100 pass through the openings on the winding roller 11 and the protective cover 5 respectively. Then move the assembly plate 63 to rotate it and break away from the restriction of the insertion rod 623 until it is adjusted to a suitable installation position. At this time, the assembly plate 63 can be used as a fixed carrier to firmly mount the entire device on the robot body. Furthermore, the entire device can be rotated according to actual needs, and the angle of the groove ring 61 can be adjusted inside the rotating ring 62 while the rotating ring 62 rotates. During this process, the block 621 will move synchronously with the rotation of the rotating ring 62, and the elastic member 622 will deform accordingly. When the device is adjusted to the desired position, the block 621 automatically embeds itself into the groove at the corresponding position of the groove ring 61 to complete the angle positioning, thereby ensuring that the device is in the best working condition.
[0042] Next, pull the charging cable 100 by moving the end of the charging cable 100 near the robot (located at the winding roller 11). As the charging cable 100 is pulled out, the triangular plate 13 rotates toward the rounded end 121 of the support plate 12 to reduce pulling resistance. After the cable 100 is pulled out to the desired length, the triangular plate 13 is restricted by the right-angled end 122 of the support plate 12, preventing the charging cable 100 from being pulled out further. The end of the charging cable 100 can then be inserted into the corresponding charging port on the robot. Subsequently, depending on the actual usage scenario, the other end of the charging cable 100 can be unwound to meet subsequent functional expansion or spatial layout requirements.
[0043] To automatically retract and extend the charging cable 100, a drive motor 32 is installed within the device. Its output shaft drives the synchronous rotation of the movable plate 33 and the end face ratchet 1 34. The end face ratchet 1 34 and the end face ratchet 2 35 form an intermittent meshing transmission relationship. When engaged, the end face ratchet 1 34 drives the sleeve 21 and its associated components to retract or release the charging cable 100. When not engaged, the end face ratchet 34 and the end face ratchet 2 35 are separated, allowing manual adjustment of the length of the charging cable 100, thus achieving fine-tuning and avoiding the uncontrollable nature of fully automatic retraction and extension.
[0044] Specifically: Engagement stage: The end face ratchet 1 34 is engaged with the end face ratchet 2 35, driving the sleeve 21 assembly to rotate, realizing the automatic retraction and extension of the charging cable body 100; Separation stage: The two ratchets are disengaged, and the winding roller 11 is no longer restricted. The charging cable body 100 can be manually pulled to adjust the length.
[0045] In this process, the reset copper sheet 36 assists in pushing the movable plate 33 and the end face ratchet 1 34 to slide and reset, thereby realizing a continuous cycle of retraction and extension action.
[0046] To enhance the stability and safety of the charging cable 100 during use, it is housed entirely within a sleeve 21, supported and shaped by traction cords 24 on either side. Furthermore, cable ties 23 secure the cable 100 at both ends, preventing displacement or deformation caused by external forces. This ensures stability in dynamic environments and extends its service life.
[0047] After use, the charging cable 100 needs to be retracted by pressing down on the push plate 42, causing it to contact and push the clamping plates 41 on both sides to close, thereby clamping the sleeve 21 and the charging cable 100 inside. During this process, the fitting 411 guides the charging cable 100's retraction path, ensuring that the charging cable 100 smoothly passes through the opening in the protective cover 5. The auxiliary roller 53 also reduces frictional resistance and improves cable retraction efficiency.
[0048] When the charging cable body 100 is retracted to the extreme position, the plug at the tail end will automatically be stuck on the outside of the clamping plate 41, effectively avoiding damage caused by excessive bending or pulling, while ensuring that the trajectory of the entire reeling process is stable and controllable.
[0049] It can be seen that through the setting of the above components, efficient management, automatic retraction and flexible installation of the robot charging cable can be achieved, which greatly improves the service life and safety of the charging cable.
[0050] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
