[0030] See also Figure 1 to Figure 2 The embodiment of the present application provides a winding structure 100 and a window cleaning base station 120 having the same. The winding structure 100 is used to wind up a collection rope, which is a power cord used to supply power to a window cleaning machine 140 and prevent the window cleaning machine 140 from crashing.

The wire drawing wheel 200 is rotatably connected to the winding wheel 300. The wire drawing wheel 200 has a receiving area 201 for accommodating the winding wheel 300. The winding wheel 300 is rotatably arranged in the receiving area 201. It can be understood that the wire drawing wheel 200 and the winding wheel 300 are coaxially rotatably arranged so that they can rotate relative to each other under the action of an external torque.

[0032] See also Figure 1 to Figure 2 The wire reel 200 is also provided with a wire groove 202 connected to the accommodating space 201. One end of the power cord passes through the wire groove 202 and is connected to the side surface of the winding wheel 300. The driving assembly 110 is used to drive the wire reel 200 and the winding wheel 300 to rotate relative to each other, so that the power cord is guided by the wire groove 202 and wound around the side surface of the winding wheel 300. It can be understood that the power cord is generally made of high-strength and flexible materials, such as a wire coated with nylon, so that the power cord can be wound and collected. For example, the wire reel 200 rotates relative to the winding wheel 300 under the drive of the driving component 110, and the winding wheel 300 remains stationary. The wire groove 202 drives the power cord to continuously rotate along the circumference of the winding wheel 300 and wind around the winding wheel 300, or the driving component 110 drives the winding disk 301 to rotate relative to the wire reel, and the power cord is guided and reeled by the wire groove 202, and is continuously and neatly wound around the winding wheel 300.

[0033] In the embodiment provided in the present application, the wire drawing wheel 200 can draw and guide the power cord through the wire groove 202, so that the part of the power cord to be wound is always located on the side surface of the winding wheel 300, and then the driving component 110 drives the wire drawing wheel 200 and the winding wheel 300 to rotate relative to each other, so that the power cord can be continuously and neatly wound around the side surface of the winding wheel 300, thereby improving the winding efficiency and reducing the labor intensity of the workers.

[0037] See also Figure 5 to Figure 6 In some embodiments, the winding wheel 200 is fixedly arranged, and the driving component 110 drives the winding wheel 300 to rotate relative to the winding wheel 200.

[0038] It can be understood that the wire reel 200 is fixed and can be fixed to the housing of the window cleaning base station 120 , and the driving component 110 drives the winding wheel 300 to rotate relative to the wire reel 200 , so that the power cord is wound on the winding drum 301 .

[0039] See also Figure 1 to Figure 2 In some embodiments, the winding wheel 200 includes a winding chassis 203 and a plurality of guide columns 204, wherein the guide columns 204 are connected to the edge of the winding chassis 203, and each of the guide columns 204 is arranged circumferentially around the winding chassis 203, and defines a accommodating area 201 together with the winding chassis 203, and any two adjacent guide columns 204 form the wire groove 202, and the winding chassis 203 is coaxially rotatably connected to the winding wheel 300.

[0040] See also Figure 1 to Figure 2 Optionally, four guide posts 204 are arranged on the wire winding chassis 203, and a power cord can be arranged in each wire groove 202, so as to realize the synchronous winding and collection of multiple power cords.

[0041] Optionally, the wire drawing chassis 203 and the guide column 204 are both made of metal materials, such as metal aluminum or iron, so as to ensure that the wire drawing wheel 200 has sufficient strength.

[0042] In some embodiments, the wire drawing wheel 200 further includes a positioning ring 205 disposed opposite to the wire drawing chassis 203 , and each of the guide columns 204 is connected to the positioning ring 205 .

[0043] It can be understood that the two ends of any guide column 204 are respectively connected to the positioning ring 205 and the wire winding chassis 203, and the positioning ring 205 can strengthen the overall strength of the wire winding wheel 200 to prevent the guide column 204 from tilting or shaking during the winding process.

[0044] See also Figure 1 to Figure 2 Optionally, when the winding wheel 300 rotates relative to the winding wheel 200, the corresponding guide column 204 can wind the power cord to prevent the power cord from bending and tangling, and make the power cord wind around the winding wheel 300.

[0045] See also Figure 1 to Figure 2In some embodiments, the wheel surface of the winding wheel 300 is further provided with a centrifugal hook 400, and the centrifugal hook 400 has a contracted state and an expanded state. When the centrifugal hook 400 is in the contracted state, the centrifugal hook 400 is stacked on the wheel surface of the winding wheel 300. When the centrifugal hook 400 is in the expanded state, the centrifugal hook 400 rotates relative to the winding wheel 300 and hooks one of the guide columns 204.

[0046] See also Figure 1 to Figure 2 It can be understood that the overall shape of the centrifugal hook 400 is crescent-shaped, and one end of the centrifugal hook 400 is rotatably connected to the wheel surface of the winding wheel 300. When the winding wheel 300 rotates to wind and collect the power cord, the free end of the centrifugal hook 400 is tilted toward the rotation center of the winding wheel 300 under the action of centrifugal force and is stacked on the wheel surface of the winding wheel 300, and is in a retracted state; when the window cleaning machine 140 crashes, the power cord is continuously released from the winding wheel 300, and the winding wheel 300 reverses. Under the action of centrifugal force, the centrifugal hook 400 rotates relative to the winding wheel 300, and the free end rotates out of the wheel surface of the winding wheel 300, and hooks one of the guide columns 204, thereby preventing the winding wheel 300 from continuing to rotate, and then preventing the window cleaning machine 140 from continuing to fall.

[0047] See also Figure 1 to Figure 2 Optionally, the winding structure 100 further includes a first tension spring, a first hanging portion 21 is provided at the free end of the centrifugal hook 400, a second hanging portion 22 is provided on the winding wheel 300, one end of the first tension spring hooks the first hanging portion 21 on the free end of the centrifugal hook 400, and the other end of the first tension spring is connected to the second hanging portion 22 on the winding wheel 300. When the centrifugal hook 400 is in a contracted state, the first tension spring can improve the stability of the centrifugal hook 400. When the winding wheel 300 is reversed, the centrifugal force overcomes the elastic deformation of the first tension spring, and the centrifugal hook 400 is in an expanded state.

[0048] See also Figure 3 to Figure 4In some embodiments, the winding structure 100 also includes a rotating shaft 104, a ratchet 402 connected to the rotating shaft 104 and having a ratchet groove 403, a driving hook 401 rotatably connected to the winding wheel 300, and a driving elastic member with elastic restoring force, wherein a plurality of ratchet grooves 403 are arranged at intervals along the circumference of the ratchet 402, one end of the driving elastic member is connected to the winding wheel 300, and the other end of the elastic member is connected to one end of the driving hook 401, and the winding wheel 300 and the winding wheel 200 are both rotatably connected to the rotating shaft 104. When the driving component 110 drives the rotating shaft 104 to rotate forward and perform the winding operation of the power cord, the driving elastic member drives the other end of the driving hook 401 to be clamped into the ratchet groove 403 under the action of the elastic force, so that the ratchet 402 rotates with the rotating shaft 104, and drives the winding wheel 300 to rotate through the driving hook 401.

[0049] See also Figure 3 to Figure 4 Optionally, when the winding wheel 300 rotates in the opposite direction under the action of external force and unwinds the power cord, the winding wheel 300 drives the driving hook 401 to overcome the elastic force of the driving elastic member, so that the driving hook 401 jumps out and disengages from the ratchet groove 403, so that the driving hook 401 does not restrict the unwinding rotation of the winding wheel 300 around the rotating axis 104.

[0050] See also Figure 3 to Figure 4 It can be understood that a plurality of ratchet teeth 404 arranged obliquely are provided on the edge of the ratchet wheel 402 , and any two adjacent ratchet teeth 404 form a ratchet groove 403 .

The two ends of the second tension spring are respectively connected to the first hook portion 31 and the second hook portion 32. The second tension spring is in a stretched state, so that when the rotating shaft 104 rotates forward, the driving hook 401 can be pulled to always stably engage in one of the ratchet grooves 403. When the winding wheel 300 rotates in the reverse direction to pay out the line, the driving hook 401 overcomes the elastic force of the second tension spring and disengages from the ratchet groove 403.

[0060] The driving wheel 102 and the driven wheel 103 are connected by a synchronous belt, which can shorten the winding time and reduce the physical exertion of workers. The synchronous belt transmission also has the following characteristics:

[0061] Precise transmission: The two ends of the synchronous belt are respectively connected to the driving wheel 102 and the driven wheel 103, and the teeth are engaged with each other, which can achieve very precise transmission and avoid sliding and transmission errors.

[0062] High efficiency: Due to the meshing between teeth, the energy transfer efficiency of synchronous belt drive is high, which can effectively reduce energy loss, improve transmission efficiency, and quickly collect power lines.

[0063] Stability: Synchronous belt transmission has good stability and reliability. It is not easy to slip or jump teeth during the transmission process, which can ensure the stable operation of the transmission mechanism.

At the same time, since the male connector and the female connector are detachable, the window cleaning machine 140 and the window cleaning base station 120 can be assembled separately on different production lines. After the assembly is completed, the window cleaning machine 140 is connected to the window cleaning base station 120 through the matching connection of the female connector and the male connector. The matching connection of the male connector and the female connector can ensure that when the window cleaning machine 140 falls from a height, the power cord will pull the window cleaning machine 140. The power cord has a built-in buffer mechanism, such as flexibility, so the window cleaning machine 140 will not fall. The male connector and the female connector are connected by threads, and the head is plus a braided wire with a buffer mechanism, which can meet the convenience of production while ensuring the safety of the window cleaning machine 140 during use.
