Specific implementation manners

[0034] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer and more understandable, the following further details this application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0035] This embodiment provides a window cleaning machine, which includes an edge collision trigger structure of the window cleaning machine. Please refer to Figures 1 to 8 , the described edge collision trigger structure of the window cleaning machine includes a window cleaning machine bottom case 1. A rotary fixed shaft 2 is provided in the inner corner area where the two side edges of the window cleaning machine bottom case 1 meet. The rotary fixed shaft 2 is connected with a collision moving part 3 that can rotate around the shaft. A side wheel 4 protruding from the two side edges of the window cleaning machine bottom case 1 is provided at the lower part of the collision moving part 3. Collision recognition mechanisms 5 that can cooperate with the collision moving part 3 are respectively provided inside the two side edges of the window cleaning machine bottom case 1. After the side wheel 4 collides with an obstacle, the collision moving part 3 rotates around the shaft and displaces to press against the collision recognition mechanism 5.

[0036] In this embodiment, a rotary fixed shaft 2 is provided in the inner corner area where the two side edges of the window cleaning machine bottom case 1 meet. This shaft is used to connect the collision moving part 3 and allow it to rotate around the shaft. Through this design, the collision moving part 3 can rotate within a certain range, thereby realizing the collision detection of obstacles. When the side wheel 4 collides with an obstacle, the collision force will be transmitted to the collision moving part 3, causing it to rotate and displace around the rotary fixed shaft 2. Under this rotational displacement, the collision moving part 3 will finally press against the collision recognition mechanism 5, causing it to generate a corresponding signal output. According to this signal output, the window cleaning machine can judge whether it encounters an obstacle and take corresponding control measures, such as stopping moving, changing the moving direction to get out of trouble, etc.

[0037] By providing the collision recognition mechanisms 5 inside the two side edges, the reliability of obstacle recognition can be improved. Specifically, each corner of the window cleaning machine has the ability to recognize obstacles in two directions, enabling the window cleaning machine to have an all-round obstacle recognition function. In addition, even if the collision recognition mechanism 5 on one side edge of a certain corner fails or malfunctions, the collision recognition mechanism 5 on the other side edge can still work normally, thus ensuring the continuity and stability of obstacle recognition.

[0038] Further, as a preferred implementation manner rather than a limitation of this solution, the collision recognition mechanism 5 includes a first installation groove 51 provided on the bottom shell 1 of the window cleaning machine. One end of the first installation groove 51 is embedded with a touch switch 52 and a collision silica gel 53. The collision silica gel 53 is arranged adjacent to the touch switch 52. An elastic wall 54 is provided on the bottom shell 1 of the window cleaning machine and extends downward into the first installation groove 51, adjacent to the collision silica gel 53 and capable of abutting against the collision silica gel 53. When the collision moving part 3 rotates and displaces around the axis and presses against the elastic wall 54, the elastic wall 54 deforms and presses against the collision silica gel 53, and further causes it to contact and turn on the touch switch 52.

[0039] In this embodiment, by providing the elastic wall 54 and the collision silica gel 53, the collision force can be effectively transmitted, and it is ensured that the touch switch 52 can be reliably triggered, thereby improving the sensitivity and reliability of obstacle recognition. The turning on of the touch switch 52 will send an electrical signal to the control system of the window cleaning machine, indicating that the window cleaning machine has encountered an obstacle. After receiving this signal, the control system can take corresponding measures, such as stopping the operation of the window cleaning machine, adjusting the working path, etc.

[0040] Further, as a preferred implementation manner rather than a limitation of this solution, collision parts 31 capable of abutting against the elastic walls 54 in two directions are respectively provided at both side ends of the collision moving part 3. A corresponding first fixing hole 32 connected to the rotation fixing shaft 2 is provided on one side of the collision moving part 3. The distances between the first fixing hole 32 and the two collision parts 31 are equal. A side wheel socket part 33 is provided on the side of the collision moving part 3 away from the first fixing hole 32.

[0041] In this embodiment, the collision parts 31 are provided at both side ends of the collision moving part 3 for abutting against the elastic walls 54 in two directions. Specifically, the two collision parts 31 respectively correspond to the elastic walls 54 in one direction. When the side wheel 4 of the window cleaning machine encounters an obstacle, the direction of the collision force corresponds to one of the collision parts 31, causing it to abut against the elastic wall 54 in the corresponding direction, and finally triggering the touch switch 52 to send an electrical signal to the control system of the window cleaning machine, accurately judging the direction of the obstacle, and thus adjusting the working path. The collision parts 31 can be convex structures or concave structures, specifically depending on the shape and position of the elastic wall 54.

[0042] Further, as a preferred implementation manner rather than a limitation of this solution, a socket limiting boss 34 is provided at the end of the side wheel socket portion 33. The cross-sectional area of the socket limiting boss 34 gradually decreases from top to bottom. Since the cross-sectional area of the socket limiting boss 34 gradually decreases from top to bottom, the side wheel 4 can be conveniently and quickly sleeved on the side wheel socket portion 33. On the other hand, the axial movement range of the side wheel 4 can be effectively limited to prevent the side wheel 4 from disengaging from the side wheel socket portion 33. A plurality of notch grooves 331 for facilitating the assembly of the side wheel 4 are evenly provided on the circumferential side of the bottom of the side wheel socket portion 33. The notch grooves 331 and the socket limiting boss 34 cooperate to form an elastic buckle structure to make the side wheel 4 easier to assemble. After the assembly is completed, the socket limiting boss 34 can buckle the side wheel 4. An interference-connected bearing 41 is provided inside the side wheel 4, and the bearing 41 is sleeved on the side wheel socket portion 33, which can make the rotation of the side wheel 4 smoother.

[0043] Further, as a preferred implementation manner rather than a limitation of this solution, a drop component 6 is further provided between the collision movable member 3 and the side wheel 4. A drop recognition device 7 movably connected to the drop component 6 is installed on the collision movable member 3. When the drop component 6 drops, it disconnects from the drop recognition device 7.

[0044] In this embodiment, when the window cleaning machine encounters a cliff or a pit during the moving process, the drop component 6 will be affected first and its state will change.

[0045] The drop recognition device 7 can monitor the state change of the drop component 6 in real time through its connection with the drop component 6. When the state of the drop component 6 changes and disconnects from the drop recognition device 7, the drop recognition device 7 will immediately sense this change and determine that the window cleaning machine has encountered a cliff or a pit.

[0046] After determining the cliff or the pit, the drop recognition device 7 will send an electrical signal to the control system of the window cleaning machine, indicating that the window cleaning machine has encountered a cliff or a pit. After receiving this signal, the control system can take corresponding measures, such as stopping the window cleaning machine from moving forward, adjusting the moving path, or issuing an alarm.

[0047] Further, as a preferred implementation manner rather than a limitation of the present solution, the dropping component 6 includes a dropping rod cover 61 movably connected to the dropping recognition device 7. A dropping rod 62 is fixedly connected to the lower end of the dropping rod cover 61. The fixed connection method can be snap connection, interference fit, bolt connection, etc. A dropping installation groove 35 matching the dropping rod cover 61 and a dropping through hole 36 communicating with the dropping installation groove 35 are provided on the side wheel socket portion 33. An installation portion 37 for installing the dropping recognition device 7 is provided on the peripheral side of the upper end of the dropping installation groove 35. The dropping rod cover 61 and the dropping rod 62 are movably arranged in the dropping installation groove 35. The bottom of the dropping installation groove 35 can abut against the bottom end of the dropping rod cover 61 to limit the dropping height of the dropping rod 62. When the dropping rod 62 drops, the dropping rod cover 61 is disconnected from the dropping recognition device 7.

[0048] In this embodiment, the state change of the dropping rod 62 will drive the dropping rod cover 61 to move in the dropping installation groove 35. When the dropping rod cover 61 moves to a certain position, it will contact or separate from the dropping recognition device 7. By contacting or separating from the dropping rod cover 61, the dropping recognition device 7 can judge the state change of the dropping rod 62 and further judge whether the window cleaning machine encounters a cliff or a pit.

[0049] Specifically, when the window cleaning machine encounters a cliff or a pit during movement, the dropping rod 62 will first drop towards the suspended area or the pit, and drive the dropping rod cover 61 connected thereto to be disconnected from the dropping recognition device 7. At this time, the dropping recognition device 7 will send an electrical signal to the control system of the window cleaning machine, indicating that the window cleaning machine encounters a cliff or a pit. After receiving this signal, the control system can take corresponding measures, such as stopping the window cleaning machine from advancing, adjusting the moving path or giving an alarm.

[0050] Further, as a preferred implementation manner rather than a limitation of the present solution, the dropping recognition device 7 includes a dropping PCBA board 71 arranged on the installation portion 37. A corresponding clamping groove for fixing the dropping PCBA board 71 is provided on the installation portion 37. A photoelectric switch 72 is provided on the dropping PCBA board 71. The dropping rod cover 61 can be connected to the photoelectric switch 72 to cut off the photoelectric signal. When the dropping rod 62 drops, the dropping rod cover 61 is separated from the photoelectric switch 72.

[0051] Specifically, when no fall occurs, the drop rod cover 61 is connected to the photoelectric switch 72 to isolate the photoelectric signal. The photoelectric switch 72 is used to detect the position change of the drop rod cover 61. When the window cleaning machine encounters a cliff or a pit during movement, the drop rod 62 will first fall into the suspended area or the pit, and drive the drop rod cover 61 connected to it to separate from the photoelectric switch 72. The isolated photoelectric signal is restored and sent to the control system of the window cleaning machine. After receiving the signal, the control system can take corresponding measures, such as stopping the window cleaning machine from moving, adjusting the moving path or issuing an alarm.

[0052] Furthermore, as a preferred embodiment of the present scheme but not a limitation, the bottom of the drop rod 62 is provided with a drop portion 63 extending and protruding along the circumferential direction of the drop rod 62, and the drop rod 62 is sleeved with an elastic member 64, one end of which abuts against the drop portion 63 and the other end abuts against the lower end surface of the sleeve limiting boss 34, so that the drop rod 62 has a tendency to detach from the photoelectric switch 72.

[0053] In this embodiment, when the window cleaning machine is working normally, the lower end of the drop rod 62 contacts the window glass, and the compression deformation of the elastic member 64 has a tendency to drive the drop rod 62 to separate from the photoelectric switch 72. When the window cleaning machine moves to the window and encounters a pit or a cliff, the lower end of the drop rod 62 loses its supporting force, and the drop rod quickly falls under the action of the elastic member 64 and separates from the photoelectric switch 72, which is conducive to rapid feedback of the fall.

[0054] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the bottom of the collision movable part 3 is provided with a movable part fixing plate 8 fixedly connected to the bottom shell 1 of the window cleaning machine; the collision movable part 3 is also provided with a second fixing hole 38, and the bottom shell 1 of the window cleaning machine is provided with a locking hole 11 corresponding to the second fixing hole 38. When a locking part is arranged between the second fixing hole 38 and the locking hole 11, the collision movable part 3 and the rotating fixed shaft 2 remain relatively stationary.

[0055] In this embodiment, when the user does not need to use the obstacle recognition function of the window cleaning machine, it can be realized by setting a locking member between the second fixing hole 38 and the locking hole 11. After the locking member is inserted into the second fixing hole 38 and the locking hole 11, it will limit the rotation of the collision movable member 3 around the rotating fixed shaft 2, so that the collision movable member 3 and the rotating fixed shaft 2 remain relatively still. In this way, the collision movable member 3 can be prevented from rotating unexpectedly, and the shaking and noise of the window cleaning machine during movement can also be reduced. It should be pointed out that in this case, the fall recognition functions of the fall assembly 6 and the fall recognition device 7 can still be realized independently.

[0056] Working principle of this utility model:

[0057] The utility model provides a window cleaning machine, comprising a bottom shell of the window cleaning machine and a collision trigger structure along the edge of the window cleaning machine. A rotating fixed shaft is provided in the inner corner area where the two sides of the bottom shell of the window cleaning machine meet, and a collision movable part that can rotate around the shaft is connected. The lower part of the collision movable part is provided with edge wheels protruding from the two sides of the bottom shell of the window cleaning machine. The two sides of the bottom shell of the window cleaning machine are provided with a collision identification mechanism that can cooperate with the collision movable part.

[0058] When the side wheel collides with an obstacle, the collision force will be transmitted to the collision movable part, causing it to rotate around the fixed axis. Under this rotational displacement, the collision movable part will eventually press against the collision recognition mechanism, causing it to generate a corresponding signal output. Based on the signal output, the window cleaning machine can determine whether it encounters an obstacle and take corresponding control measures, such as stopping movement, changing the direction of movement to escape, etc.

[0059] The collision recognition mechanism includes a first mounting groove provided on the bottom shell of the window cleaning machine, and a light touch switch and a collision silica gel are embedded in one end of the groove. An elastic wall extending downward into the first mounting groove and arranged adjacent to and abutting against the collision silica gel is provided on the bottom shell of the window cleaning machine. When the collision movable part rotates and displaces around the axis to press against the elastic wall, the elastic wall deforms and presses against the collision silica gel, thereby connecting it to open the light touch switch.

[0060] The two side ends of the collision movable part are provided with collision parts which can respectively abut against the elastic walls in two directions, and are used to abut against the elastic walls in two directions, and finally trigger the touch switch to send an electrical signal to the control system of the window cleaning machine to accurately determine the direction of the obstacle.

[0061] A drop assembly is also arranged between the collision movable part and the side wheel, and a drop identification device movably connected with the drop assembly is installed on the collision movable part. When the drop assembly falls, it is disconnected from the drop identification device.

[0062] The drop assembly includes a drop rod cover movably connected to the drop identification device, and the lower end of the drop rod cover is fixedly connected to the drop rod. The side wheel sleeve portion is provided with a drop installation groove matching the drop rod cover and a drop through hole connected to the drop installation groove. The drop rod cover and the drop rod are movably arranged in the drop installation groove.

[0063] The drop identification device includes a drop PCBA board arranged on the mounting part, and a photoelectric switch is arranged on the drop PCBA board. A drop portion extending and protruding along the circumference of the drop rod is arranged at the bottom of the drop rod, and an elastic member with one end abutting against the drop portion and the other end abutting against the lower end surface of the sleeve limit boss is sleeved on the drop rod, so that the drop rod has a tendency to separate from the photoelectric switch.

[0064] When the window cleaning machine encounters a cliff or a pit during movement, the dropping rod will first drop towards the suspended area or into the pit, driving the dropping rod cover connected to it to disconnect from the dropping recognition device. At this time, the dropping recognition device will send an electrical signal to the control system of the window cleaning machine, indicating that the window cleaning machine has encountered an obstacle.

[0065] The bottom of the collision movable part is provided with a movable part fixing plate fixedly connected to the bottom shell of the window cleaning machine. The collision movable part is also provided with a second fixing hole, and the bottom shell of the window cleaning machine is provided with a locking hole corresponding to the second fixing hole. When a locking piece is arranged between the second fixing hole and the locking hole, the collision movable part and the rotating fixed shaft remain relatively stationary. This can prevent the collision movable part from accidentally rotating and also reduce the shaking and noise of the window cleaning machine during movement.

[0066] The above are the implementation manners provided in combination with specific contents, and it is not considered that the specific implementation of this application is only limited to these descriptions. Any structure similar to the method of this application, or any technical deduction or replacement made under the premise of the concept of this application, should be regarded as the protection scope of this application.
