Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0027] Please see attached Figure 1 To Attachment Figure 5 , this embodiment provides a window cleaning machine, which includes a window edge collision triggering device of the window cleaning machine.
[0028] Among them, the window edge collision trigger device of the window cleaning machine comprises a window cleaning machine bottom shell 1 and side wheels 2 arranged at the intersection of two side edges of the window cleaning machine bottom shell 1 and protruding from two side edges of the window cleaning machine bottom shell 1; the window cleaning machine bottom shell 1 is provided with a side wheel sleeve portion 11 and a button mounting portion 12; the button mounting portion 12 is arranged on one side of the side wheel sleeve portion 11, and a button mounting groove 121 is provided on the button mounting portion 12; a light touch button 3 is provided in the button mounting groove 121; a light touch docking port 122 connected to the button mounting groove 121 is provided on one side of the button mounting portion 12 close to the side wheel sleeve portion 11; the side wheel 2 is movably sleeved on the side wheel sleeve portion 11; after the side wheel 2 collides with an obstacle, it is displaced along the radial direction of the side wheel sleeve portion 11 to press the light touch button 3.
[0029] In this embodiment, there is a fitting gap between the edge wheel 2 and the edge wheel socket 11. When the window cleaning machine moves to the window and collides with an obstacle, the edge wheel 2 is displaced radially along the edge wheel socket 11 to press the touch button 3. After the touch button 3 is pressed, an electrical signal is generated to realize timely feedback, which is beneficial for the window cleaning machine to receive collision feedback in time and adjust the direction in time to resume normal operation.
[0030] Furthermore, the button mounting portion 12 is disposed on a side of the side wheel sleeve portion 11 away from the side edge of the window cleaning machine bottom shell 1. In this embodiment, since the button mounting portion 12 is disposed on a side of the side wheel sleeve portion 11 away from the side edge of the window cleaning machine bottom shell 1, when the side edge of the window cleaning machine bottom shell 1 approaches an obstacle at the window edge, the side wheel 2 is displaced in a radial direction of the side wheel sleeve portion 11 in a direction away from the obstacle, thereby pressing the light touch button 3 located in the button mounting groove 121 of the button mounting portion 12.
[0031] Preferably, side wheels 2 and light-touch buttons 3 cooperating with the side wheels 2 are provided at the intersection of each of the four side edges of the bottom shell 1 of the window cleaning machine. Therefore, no matter if the window cleaning machine collides with an obstacle near the window during the forward or backward process, feedback of the collision can be given in time, which is conducive to the window cleaning machine to resume normal operation in time.
[0032] Furthermore, a sleeve limiting protrusion 111 is provided on the circumferential side of the end of the side wheel sleeve portion 11, and the cross-sectional area of the sleeve limiting protrusion 111 gradually decreases from top to bottom. During installation, the side wheel 2 is sleeved on the side wheel sleeve portion 11 from bottom to top, and its structure is simple and easy to install. The cross-sectional area of the sleeve limiting protrusion 111 gradually decreases from top to bottom, which can make the side wheel 2 quickly sleeved with the side wheel sleeve portion 11, and can effectively prevent the side wheel 2 from detaching from the side wheel sleeve portion 11 after the sleeve connection is completed.
[0033] Furthermore, the window edge collision trigger device of the window cleaning machine of the present embodiment also includes a drop rod 4 and a drop PCBA board 5, the drop PCBA board 5 is provided with a photoelectric switch 51, the side wheel sleeve portion 11 is provided with a drop installation groove 112 and a drop through hole 113 connected to the drop installation groove 112, a PCBA installation portion 13 is provided above the side wheel sleeve portion 11 and located on the surrounding side of the drop through hole 113, the drop PCBA board 5 is arranged on the PCBA installation portion 13, the drop rod 4 is movably arranged in the drop installation groove 112, the upper end of the drop rod 4 passes through the drop through hole 113 and is connected to the photoelectric switch 51, and the drop rod 4 is detached from the photoelectric switch 51 when falling. In this embodiment, when the window cleaning machine is working normally, the lower end of the drop rod 4 is in contact with the window glass, and the upper end of the drop rod 4 is connected to the photoelectric switch 51 on the drop PCBA board 5. When the window cleaning machine moves to the window and encounters a pit or a cliff, the drop rod 4 falls and separates from the photoelectric switch 51. The window cleaning machine can provide timely feedback based on the connection status between the drop rod 4 and the photoelectric switch 51, which is conducive to the window cleaning machine receiving the drop feedback in time and making timely adjustments to resume normal operation.
[0034] Furthermore, the PCBA mounting portion 13 is provided with a PCBA clamping groove 131 for clamping with the falling PCBA board 5, and a switch positioning groove 132 for positioning and installing the photoelectric switch 51, and the switch positioning groove 132 is communicated with the falling through hole 113. In this embodiment, the falling PCBA board 5 is clamped in the PCBA clamping groove 131, the photoelectric switch 51 is installed in the switch positioning groove 132, and the upper end of the falling rod 4 passes through the falling through hole 113 and is just positioned and connected with the photoelectric switch 51. The structure is simple and the installation is convenient.
[0035] Furthermore, the window edge collision triggering device of the window cleaning machine of the present embodiment further comprises an elastic member 6, and the elastic member 6 is connected to the drop rod 4 so that the drop rod 4 has a tendency to separate from the photoelectric switch 51. When the window cleaning machine is working normally, the lower end of the drop rod 4 contacts the window glass, and the elastic deformation of the elastic member 6 has a tendency to drive the drop rod 4 to separate from the photoelectric switch 51. When the window cleaning machine moves to the window edge and encounters a pit or a cliff, the lower end of the drop rod 4 loses its supporting force, and the drop rod quickly falls under the action of the elastic member 6 and separates from the photoelectric switch 51, which is conducive to rapid feedback of the fall.
[0036] Furthermore, the bottom of the drop rod 4 is provided with a drop portion 41 extending and protruding along the circumferential direction of the drop rod 4, and the elastic member 6 is sleeved on the drop rod 4, and one end of the elastic member 6 abuts against the drop portion 41, and the other end abuts against the upper end surface of the drop installation groove 112. The elastic member 6 of this embodiment is a spring, which has a simple structure and is easy to install.
[0037] Furthermore, the bottom of the falling portion 41 is hemispherical. The hemispherical structure has a small contact area with the window glass and small friction.
[0038] Furthermore, the falling portion 41 is provided with a guide plate 411 extending along the axial direction of the falling rod 4. In this embodiment, the guide plate 411 has the same shape as the falling installation groove 112, and the setting of the guide plate 411 can make the falling rod 4 move more smoothly when falling along the falling installation groove 112.
[0039] Further, a switch connection part 42 is provided at the top of the drop rod 4, and the switch connection part 42 and the drop through hole 113 are both rectangular, and the long side of the switch connection part 42 is less than or equal to the long side of the drop through hole 113, and the wide side of the switch connection part 42 is less than or equal to the wide side of the drop through hole 113, and the long side of the switch connection part 42 is greater than the wide side of the drop through hole 113. During installation, the long side of the switch connection part 42 of the drop rod 4 is first aligned with the long side of the drop through hole 113, and the wide side of the switch connection part 42 is aligned with the wide side of the drop through hole 113, and then the switch connection part 42 of the drop rod 4 is passed through the drop through hole 113 from bottom to top, and then the drop rod 4 is rotated so that the long side of the switch connection part 42 of the drop rod 4 is parallel to the wide side of the drop through hole 113, and finally the switch connection part 42 of the drop rod 4 is connected to the photoelectric switch 51 on the drop PCBA board 5. When the window cleaning machine moves to the window and encounters a pit or a cliff, the drop bar 4 falls and separates from the photoelectric switch 51. Since the long side of the switch connection part 42 is larger than the wide side of the drop through hole 113, the drop bar 4 stops falling when the switch connection part 42 contacts the drop through hole 113. In this embodiment, the drop through hole 113 cooperates with the switch connection part 42, which can realize the rapid installation of the drop bar 4 on the one hand, and effectively limit the drop bar 4 on the other hand, to prevent the drop bar 4 from completely separating from the drop installation groove 112 when falling.
