Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 7 As shown, this utility model embodiment provides an elastic triggering device applied to a window cleaning machine, comprising:

[0030] The system includes a collision support frame 21 for supporting the elastic triggering device, a disengagement detection structure for detecting longitudinal state, an edge-to-edge detection structure 23 for detecting lateral state, and an optical coupler detection structure 24 for identifying the state of the window cleaning machine. The disengagement detection structure detects the disengagement by moving the collision support frame 21 relative to the optical coupler detection structure 24. The edge-to-edge detection structure 23 is connected to the collision support frame 21. The collision support frame 21 has a connecting cavity 211 for restricting the movement of the disengagement detection structure. The disengagement detection structure has a first collision connector 221 and a second collision connector 222. 2. The first collision connector 221 is connected to the first collision connector 221 through the movable connecting cavity 211, and the first collision connector 221 is moved relative to the optical coupler detection structure 24 through the second collision connector 222. The optical coupler detection structure 24 is connected to the main control structure of the window cleaning machine. By detecting the movement state of the first collision connector 221 relative to the optical coupler detection structure 24 and feeding it back to the main control structure, the normal state, disengagement state or edge contact state of the window cleaning machine is identified, so as to trigger the corresponding control program of the window cleaning machine, ensuring the normal operation of the window cleaning machine and improving the safety of the window cleaning machine during operation.

[0031] Specifically, the first collision connector 221 is provided with a collision connector light-shielding part 2211 and a collision connector fastening part 2212. The collision connector light-shielding part 2211 is connected to the collision connector fastening part 2212. The collision connector fastening part 2212 is connected to the second collision connector 222 to ensure the reliability of the connection between the first collision connector 221 and the second collision connector 222. Thus, the second collision connector 222 can drive the collision connector light-shielding part 2211 to move relative to the optical coupler detection structure 24. In this embodiment of the present invention, the collision connector light-shielding part 2211 is provided with... It has a movable light-shielding part 22111 and a movable light-shielding mating part 22112. The length of the movable light-shielding part 22111 is greater than that of the movable light-shielding mating part 22112 to ensure that the movable light-shielding part 22111 and the movable light-shielding mating part 22112 form a light-transmitting port after being connected. The collision connector light-shielding part 2211 is driven to move up and down relative to the optical coupler detection structure 24 through the second collision connector 222. Then, the collision connector light-shielding part 22111 moves up and down relative to the optical coupler detection structure 24 to switch between light-shielding by the movable light-shielding part 22111 and light-transmitting through the light-transmitting port for status recognition.

[0032] When the window cleaning machine is in normal working condition, the second collision connector 222 moves longitudinally due to contact with the area to be cleaned, and lifts the first collision connector 221, causing the light-shielding part 2211 of the collision connector to switch to the light-transmitting port and enter normal working condition; under the premise that the window cleaning machine is in normal working condition, the edge detection structure 23 abuts against the cliff edge and is squeezed laterally by the reaction force of the cliff edge, thereby driving the collision support frame 21 to move laterally, so that the second collision connector 222 in the movable connecting cavity 211 moves laterally. It also moves laterally; as the second collision connector 222 moves laterally, it causes the first collision connector 22 to move relative to it, thereby resetting the moving light-shielding part 22111 and causing the window cleaning machine to enter the edge-touching state; when the second collision connector 222 is not subjected to the squeezing action of the contact area to be cleaned, the moving light-shielding part 22111 is in its original state and does not undergo any relative movement, causing the window cleaning machine to enter the disengagement state; this design effectively ensures the continuity and stability of detection through the bidirectional contact detection structure, thereby improving the detection sensitivity and detection reliability of the triggering device.

[0033] Furthermore, the optocoupler detection structure 24 includes an optocoupler support plate 241, an optocoupler input terminal 242, and an optocoupler output terminal 243. The optocoupler input terminal 242 and the optocoupler output terminal 243 are connected to the optocoupler support plate 241. The collision connector light-shielding part 2211 is disposed between the optocoupler input terminal 242 and the optocoupler output terminal 243, and shields the optocoupler input terminal 242 and the optocoupler output terminal 243 from the light. In this embodiment, the optocoupler input terminal 242 is used to emit infrared light, and the optocoupler output terminal 243 is used to receive infrared light. When the collision connector light-shielding part 2211 is switched to the light-transmitting port, the optocoupler output terminal 243 receives infrared light from the light-transmitting port. The infrared light emitted from the input terminal 242 of the optocoupler causes the optocoupler detection structure 24 to output a low level to the main control structure, which then identifies it as a normal working state. When the movable light-shielding part 22111 is in its original state and has not moved relative to the main control structure, it blocks the infrared light emitted from the input terminal 242 of the optocoupler, preventing the infrared light from reaching the output terminal 243 of the optocoupler. The optocoupler detection structure 24 then outputs a high level to the main control structure, which then identifies the high level triggered in the normal working state as a contact state and the high level triggered in the abnormal working state as a disengagement state. This design effectively improves the detection sensitivity of the window cleaning machine through the triggering device.

[0034] Furthermore, the collision connector fastening part 2212 is provided with a fastening part mounting position 22121 for limiting the second collision connector 222; the second collision connector 222 is connected to the fastening part mounting position 22121 through a first threaded connector to improve the stability of the connection between the second collision connector 222 and the collision connector fastening part 2212, so that the second collision connector 222 can drive the collision connector light-shielding part 2211 to move relative to each other by moving the collision connector light-shielding part 2211 or the light-transmitting port state to adjust the output low level or high level of the optocoupler detection structure 24, effectively improving the detection sensitivity and detection reliability of the triggering device.

[0035] Furthermore, the second collision connector 222 is provided with a collision drop bar 2221 for passing through the movable connecting cavity 211 and a collision contact portion 2222 for limiting the maximum displacement of the second collision connector 222. The collision contact portion 2222 is connected to the collision drop bar 2221, and the collision contact portion 2222 and the collision drop bar 2221 are integrally formed. The collision contact portion 2222 can abut against the outside of the movable connecting cavity 211 to limit the maximum longitudinal displacement of the second collision connector 222, thereby shortening the reset time of the first collision connector 221 and enhancing the sensitivity of the triggering device. The collision drop bar 2221 is fastened to the fastening mounting position 22121, so that the longitudinal or lateral movement of the collision drop bar 2221 can drive the light-shielding part 2211 of the collision connector to move up and down, thereby improving the stability of the state switching of the light-shielding part 2211 of the collision connector.

[0036] Furthermore, the impact drop lever 2221 is provided with impact drop lever protrusions 22211 and impact drop lever fastening positions 22212. Multiple impact drop lever protrusions 22211 are equidistantly arranged on one side of the impact drop lever 2221. In this embodiment, preferably, three impact drop lever protrusions 22211 are provided. The fastening mounting position 22121 is provided with a first fastening mounting position 221211 and a second fastening mounting position 221212. The first fastening mounting position 221211 corresponds one-to-one with the impact drop lever protrusions 22211 to ensure that the impact drop lever protrusions 22211 are connected to the... Within the first fastening mounting position 221211, the collision drop bar 2221 will not rotate during longitudinal movement, and during lateral movement, the collision drop bar 2221 can drive the collision connector light-shielding part 2211 to move relative to the collision connector fastening part 2212, thereby improving the sensitivity of the trigger device's recognition; the second fastening mounting position 221212 is a countersunk hole design, and the first threaded part fastens the collision connector fastening part 2212 to the collision drop bar fastening position 22212 through the second fastening mounting position 2212212, thereby enhancing the reliability of the trigger device connection.

[0037] Furthermore, the edge detection structure 23 is provided with a first edge detection structure fastening position 231 and a second edge detection structure fastening position 232, and the collision support frame 21 is also provided with a first collision bracket locking part 212 and a second collision bracket locking part 213; the first edge detection structure fastening position 231 and the second edge detection structure fastening position 232 are respectively connected to the first collision bracket locking part 212 and the second collision bracket locking part 213 to limit the edge detection structure 23; this design ensures that the edge detection structure 23 is stably connected to the front of the collision support frame 21. The ease of installation and disassembly of the edge detection structure 23 is improved, thereby enhancing the convenience of subsequent maintenance of the triggering device. In this embodiment, both the first edge detection structure fastening position 231 and the second edge detection structure fastening position 232 are groove-shaped designs. Under the premise of ensuring that the first collision bracket snap-fit ​​part 212 and the second collision bracket snap-fit ​​part 213 are securely connected, the edge detection structure 23 can rotate through the first edge detection structure fastening position 231 and the second edge detection structure fastening position 232 when it encounters a cliff edge, thereby reducing the impact force on the triggering device.

[0038] Furthermore, the elastic triggering device for a window cleaning machine provided in this embodiment of the present invention further includes a first elastic reset member 25 for resetting after the edge detection structure 23 has shifted laterally, and a second elastic reset member 26 for resetting after the second collision connector 222 has shifted longitudinally. The collision support frame 21 is also provided with a first elastic mounting position 214. One end of the first elastic reset member 25 is connected to the first elastic mounting position 214, and the other end abuts against the window cleaning machine to ensure that when the window cleaning machine is removed from the edge-touching state, the light-shielding part 2211 of the collision connector passes through the first elastic reset member 25. The system performs a reset; simultaneously, the first elastic reset member 25 ensures that under normal working conditions, when the edge detection structure 23 is not subjected to compression and undergoes lateral displacement, the window cleaning machine will not enter the edge-touching state, effectively improving the stability of the triggering device; one end of the second elastic reset member 26 is connected to the second collision connector 222, and the other end is connected to the movable connecting cavity 211, ensuring that after the window cleaning machine leaves the area to be cleaned, the second collision connector 222 automatically resets and drives the first collision connector 221 to reset, thereby entering the disengagement state, effectively improving the detection sensitivity of the triggering device.

[0039] Furthermore, the collision contact portion 2222 is provided with a collision contact portion limiting groove 22221, and the movable connecting cavity 211 is provided with a collision drop rod limiting hole 2111. The collision drop rod limiting hole 2111 is provided with a collision drop rod protrusion limiting groove 21111, and a spring limiting protrusion 2112 is also provided outside the collision drop rod limiting hole 2111. The collision drop rod protrusion 22211 is connected to the collision drop rod protrusion limiting groove 21111, and the collision drop rod protrusion 22211 is limited by the collision drop rod protrusion limiting groove 21111 to ensure that the collision drop rod 22211 is positioned within the groove. 221 will not rotate during operation, improving the stability of the triggering device; one end of the second elastic reset member 26 is connected to the spring limiting protrusion 2112, and the other end is connected to the collision contact limiting groove 22221, so as to prevent the second collision connector 222 from loosening due to vibration or impact during operation when the second collision connector 222 undergoes longitudinal or lateral displacement, ensuring that the second collision connector 222 is always in a stable connection state, so that the second collision connector 222 can automatically return to its original state, thereby ensuring the stability of the triggering device during use.

[0040] Furthermore, the collision support frame 21 is also provided with a third collision bracket snap-fit ​​part 215, and the collision support frame 21 is connected to the window cleaning machine through the third collision bracket snap-fit ​​part 215; this design modularizes the triggering device, which facilitates the quick assembly and disassembly of the triggering device on the cleaning machine and improves the convenience of later maintenance of the triggering device.
