Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to an automatic cable retraction device inside a window cleaning machine base station. Background Technology

[0002] Currently, most mainstream window cleaning robot base stations on the market use manual operation buttons as the core control method to achieve the motor-driven cable retraction and deployment function. This design is based on mechanical interaction logic, where physical buttons on the top or side of the base station trigger internal circuit signals, thereby driving the motor to rotate the cable reel and complete the automatic retrieval of power cords, safety ropes, or composite cables.

[0003] However, without pressing the button, the base station will not retract the cable or detect the degree of cable looseness. During the operation of the window cleaning machine, the loose cable is prone to tangling, knotting, or even falling to the ground, causing safety hazards and making it easy for people to trip over it. Utility Model Content

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 9This utility model provides an automatic cable reel device inside a window cleaning machine base station, including a housing 1. A cable reel 2 is rotatably mounted inside the housing 1, and a cable 3 is wound on the reel 2. A cable reel fixing bracket 4 is also mounted inside the housing 1 via a support rod, with the reel 2 located below the cable reel fixing bracket 4. A fixing plate 5 is mounted on one end of the cable reel fixing bracket 4 near the housing 1 via a connecting rod. Springs 7 are mounted on the outer sides of both the fixing plate 5 and the cable reel fixing bracket 4, and a limit switch 6 is also mounted on the outer side of the cable reel fixing bracket 4. Each of the fixed brackets 4 has a sliding groove 8, and a take-up shaft 9 is slidably arranged between the two sliding grooves 8. Each end of the take-up shaft 9 is provided with a bushing 21. A roller 10 is rotatably arranged on the take-up shaft 9, and the cable 3 is wrapped around the outside of the roller 10 and extends out of the outer shell 1. The two bushings 21 are respectively connected to the corresponding springs 7, and one of the bushings 21 is located at the detection end of the limit switch 6. The rotating end of the take-up reel 2 is connected to a gearbox 11. The gearbox 11 is arranged on the take-up fixed bracket 4, and the gearbox 11 is driven by a motor 12.

[0024] In this embodiment, by setting up components such as the take-up reel 2, the limit switch 6, the spring 7, and the take-up shaft 9, the automatic take-up and tension adjustment of the cable 3 is realized. When the window cleaning machine is working and the cable 3 becomes loose, the spring 7 pulls the take-up shaft 9 and the roller 10 downward, triggering the limit switch 6, which in turn starts the motor 12 to drive the take-up reel 2 to take up the cable until the cable 3 is taut. This design effectively avoids the safety hazards caused by the cable 3 getting tangled, knotted, or loose, improves the safety and efficiency of the window cleaning machine, and reduces the need for manual monitoring.

[0025] Furthermore, bearings 13 are provided at the connection between the take-up reel 2 and the outer casing 1, and at the connection between the roller 10 and the take-up shaft 9.

[0026] In this embodiment, bearings 13 are provided at the connection between the take-up reel 2 and the housing 1, and at the connection between the roller 10 and the take-up shaft 9, which significantly reduces the frictional resistance between the components and makes the rotation of the take-up reel 2 and the roller 10 smoother. This not only improves the efficiency of take-up and undoing, but also reduces wear caused by friction, extends the service life of the device, and ensures the stability and reliability of the take-up process.

[0027] Furthermore, a sensor fixing bracket 14 is provided at the connection between the take-up reel 2 and the outer shell 1, a photoelectric sensor 15 is provided on the sensor fixing bracket 14, and a rotating conductive ring 16 is provided inside the take-up reel 2.

[0028] In this embodiment, the photoelectric sensor 15 can accurately calculate the cable reeling distance, providing key data for the control program and ensuring the accuracy of the cable reeling; while the rotating conductive ring 16 ensures the continuous power supply of the window cleaning machine during the rotating cable reeling process, avoiding the power outage problem caused by the rotation of the cable 3, and improving the overall performance of the device.

[0029] Furthermore, the automatic cable retraction device inside the window cleaning machine base station also includes a middle cover 17, which has a cable outlet hole 18 and a cable outlet assembly at the cable outlet hole 18. The middle cover 17 is located below the outer shell 1, and the cable 3 passes through the cable outlet assembly.

[0030] Furthermore, the cable exit assembly includes multiple guide rollers 19 and a cable exit frame 20. The multiple guide rollers 19 are rotatably connected to the cable exit frame 20 and are arranged in a triangular shape inside the cable exit frame 20. The cable exit frame 20 is fixedly connected to the middle cover 17 and is located at the cable exit frame, and the cable 3 passes through the multiple guide rollers 19.

[0031] In this embodiment, the cable 3 is guided by multiple guide wheels 19, which effectively avoids twisting and knotting of the cable 3, ensuring the continuity and stability of the window cleaning machine's operation.

[0032] In this invention, when the window cleaning machine starts working and moves away from the base station, it pulls out the cable 3 wound on the take-up reel 2. As the window cleaning machine moves, the cable 3 gradually loosens. At this time, the spring 7 pulls the take-up shaft 9 and the roller 10 rotatably mounted on it downwards until the roller 10 reaches its maximum displacement, triggering the limit switch 6. After the limit switch 6 is triggered, the motor 12 is started through the control program. The motor 12 decelerates through the gears of the gearbox 11 and drives the take-up reel 2 to take in the cable at a low speed of 0.02 m / s until the cable 3 is taut. When the cable 3 is taut, it will pull the roller 10 and the take-up shaft 9 upwards, away from the limit switch 6. At this time, the motor 12 stops running, and the take-up reel 2 stops retrieving the cable 3. When the window cleaning machine moves again and causes the cable 3 to loosen, the above process will be repeated, thereby realizing the automatic take-up and tension adjustment of the cable 3. At the same time, the photoelectric sensor 15 will calculate the take-up distance to ensure the accuracy of take-up, while the rotating conductive ring 16 will ensure the continuous power supply of the window cleaning machine during the rotating take-up process. The cable 3 is led out in an orderly manner through the cable outlet assembly on the middle cover 17, avoiding the cable 3 from becoming tangled and twisted.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
