Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of window cleaning machines, in particular to an anti-collision and anti-fall component. Background Art
[0002] Window cleaning machines are permanent, dedicated equipment used for cleaning and maintaining the exterior facades and skylight roofs of high-rise buildings. Different designs are tailored to the building's height, facade and roof structure, load capacity, and available space for the equipment. Safety, cost-effectiveness, and practicality must be considered, ensuring the installed machine is compatible with the building and does not detract from its aesthetics. Anti-collision and anti-fall components are crucial components of window cleaning machines, but existing technologies often require complex detection methods for these features, resulting in prohibitive production costs. Summary of the Invention
[0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an anti-collision and anti-fall component.
[0004] To achieve the above-mentioned purpose, an anti-collision and anti-fall component is provided, including: a switch upper shell, a switch bracket is arranged in the switch upper shell, a leaf switch is arranged on the switch bracket, an anti-collision switch push rod is arranged on the right side of the switch upper shell, a through hole is opened on the right side of the switch upper shell, and the left side of the anti-collision switch push rod passes through the through hole and is connected to the right side of the leaf switch, an anti-collision part is provided at the bottom of the anti-collision switch push rod, a bearing is provided on the outside of the anti-collision part near the bottom, and a bearing sleeve is provided on the bearing outer sleeve.
[0005] According to the anti-collision and anti-drop component, a switch lower shell is provided at the bottom of the switch upper shell, and an infrared light sensor switch is provided at the bottom of the switch lower shell.
[0006] According to the anti-collision and anti-drop assembly, a switch return spring is connected between the switch bracket and the leaf switch.
[0007] According to the anti-collision and anti-drop component, a drop rod is provided inside the bearing sleeve, and the top end of the drop rod is connected to the bearing sleeve.
[0008] According to the anti-collision and anti-drop assembly, the drop rod sleeve is provided with a drop rod reset spring, and the top and bottom ends of the drop rod reset spring are respectively connected to the bottom of the anti-collision part and the top of the drop rod.
[0009] The above solution has at least one of the following beneficial effects:
[0010] 1. This technical solution has collision detection and anti-fall detection functions, reducing the risk of safety accidents when cleaning windows.
[0011] 2. This technical solution is designed for cleaning windows and doors with framed edges. Because the diameter of the bearing sleeve is slightly larger than the diameter of the machine body, when the machine reaches the edge of a door or window and collides with the frame, the bearing sleeve will collide with the frame before the machine body. Furthermore, the bearing sleeve is connected to the anti-collision member via a bearing. Under the action of the collision force, the bearing drives the anti-collision switch push rod to move. The other end of the anti-collision switch push rod blocks the photoelectric sensor, causing light to change, thereby generating an electrical signal. The PCB transmits this electrical signal to the window cleaning machine's main control unit, changing the driving trajectory and ultimately achieving collision detection.
[0012] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.
[0020] Reference Figures 1 to 3The embodiment of the utility model is an anti-collision and anti-fall component, which includes a switch upper shell 1, a switch bracket 3 is arranged in the switch upper shell 1, a leaf switch 2 is arranged on the switch bracket 3, a switch return spring 4 is connected between the switch bracket 3 and the leaf switch 2, an anti-collision switch push rod 7 is arranged on the right side of the switch upper shell 1, a through hole is opened on the right side of the switch upper shell 1, and the left side of the anti-collision switch push rod 7 passes through the through hole and is connected to the right side of the leaf switch 2, a switch lower shell 5 is arranged at the bottom of the switch upper shell 1, and an infrared light sensor switch 6 is arranged at the bottom of the switch lower shell 5.
[0021] The bottom of the anti-collision switch push rod 7 is provided with an anti-collision member 10. A bearing 9 is sleeved on the outside of the anti-collision member 10 near the bottom. A bearing sleeve 8 is provided on the outer surface of the bearing 9. A drop rod 12 is sleeved inside the bearing sleeve 8. The top end of the drop rod 12 is connected to the bearing sleeve 8. The drop rod 12 is sleeved with a drop rod return spring 11. The top and bottom ends of the drop rod return spring 11 are respectively connected to the bottom of the anti-collision member 10 and the top of the drop rod 12. Through this structure, it has collision detection and anti-drop detection functions, reducing the risk of safety accidents when cleaning windows.
[0022] Working Principle: For use in cleaning doors and windows with frames, because the diameter of the bearing sleeve is slightly larger than the diameter of the machine body, when the machine reaches the edge of the door or window and collides with the frame, the bearing sleeve 8 will collide with the frame before the machine body. Furthermore, the bearing sleeve 8 is connected to the anti-collision member 10 via the bearing 9. Under the action of the collision force, the bearing 9 drives the anti-collision switch push rod 7 to move. The other end of the anti-collision switch push rod 7 blocks the photoelectric sensor, causing the light to change, thereby generating an electrical signal. The PCB transmits this electrical signal to the main control unit of the window cleaning machine, changing the driving trajectory and ultimately achieving collision detection.
[0023] Anti-drop detection: When cleaning frameless doors and windows, the machine's own weight compresses the drop bar 12, shortening it. When the machine reaches the edge of the door or window, it extends beyond the machine's edge. After losing its own weight, the elastic potential energy of the drop bar return spring 11 causes the drop bar 12 to slightly pop out. This drives the anti-collision switch push rod 7 to block the photoelectric sensor, causing a change in light and generating an electrical signal. The PCB transmits this signal to the window cleaning machine's main control unit, altering the machine's trajectory and ultimately achieving anti-drop detection. The drop bar return spring 11 resets both the drop bar 12 and the bearing sleeve 8.
[0024] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
