Abstract
Description
[Technical Field]
[0001] This application belongs to the field of window cleaning robot technology, specifically relating to a collision triggering mechanism for a window cleaning machine and a window cleaning machine. [Background Technology]
[0002] Existing window cleaning machines typically employ a collision detection mechanism using a yaw-triggered switch on a corner wheel. When the corner wheel is subjected to forward pressure, the yaw displacement triggers a collision signal. However, in actual operation, if the window cleaning machine contacts an obstacle at a 45-degree angle, such as... Figure 8 As shown, the direction of the compressive force on the corner wheel is orthogonal to the direction of the switch triggering, which causes the corner wheel to be unable to generate an effective yaw displacement. The collision switch assembly cannot be reliably triggered, causing the equipment to be unable to detect the collision in time and continue to operate, resulting in the risk of equipment damage and cleaning blind spots. [Utility Model Content]
[0003] In order to solve the problem that the collision switch cannot be triggered when the window cleaning machine collides with an obstacle at an oblique angle due to the failure of the corner wheel, this application provides a collision triggering mechanism for the window cleaning machine and the window cleaning machine.
[0004] This application is achieved through the following technical solution:
[0005] A collision triggering mechanism for a window cleaning machine includes a bottom shell of the window cleaning machine. A rotating fixed shaft is provided in the inner corner area where adjacent two sides of the bottom shell meet. An angle wheel fixing member is slidably connected to the rotating fixed shaft and can rotate around the rotating fixed shaft. An angle wheel fixing member is provided with an angle wheel that partially protrudes outward from the outer contour of the bottom shell of the window cleaning machine. A collision switch assembly is provided on the bottom shell of the window cleaning machine for the angle wheel fixing member to cooperate with. When the angle wheel is squeezed by an obstacle, the angle wheel fixing member rotates around the shaft or slides to press against the collision switch assembly.
[0006] As described above, in a window cleaning machine collision triggering mechanism, the corner wheel fixing member is provided with a clearance groove for the rotating fixing shaft to pass through. The rotating fixing shaft slides along the clearance groove to cause the corner wheel fixing member to collapse into the bottom shell of the window cleaning machine until it presses against the collision switch assembly.
[0007] As described above, a window cleaning machine collision triggering mechanism includes a collision switch assembly comprising a first switch disposed on the bottom shell of the window cleaning machine and located on the side of the corner wheel fixing member rotating in the forward direction around the axis, and a second switch located on the side of the corner wheel fixing member rotating in the reverse direction around the axis.
[0008] As described above, a collision triggering mechanism for a window cleaning machine includes a first elastic abutment and a second elastic abutment on the bottom shell of the window cleaning machine. The first elastic abutment is located between the corner wheel fixing member and the first switch, and the second elastic abutment is located between the corner wheel fixing member and the second switch. When the corner wheel fixing member rotates around its axis or collapses inward toward the bottom shell of the window cleaning machine to press against the first elastic abutment and / or the second elastic abutment, the first elastic abutment and / or the second elastic abutment deforms and presses against the first switch and / or the second switch.
[0009] As described above, in a window cleaning machine collision triggering mechanism, the end of the clearance groove near the corner wheel is the collision part, and the end away from the corner wheel is the reset part. When the rotating fixed shaft slides along the clearance groove to abut against the collision part, the corner wheel fixing member simultaneously triggers the first switch and the second switch.
[0010] As described above, in a window cleaning machine collision triggering mechanism, when the rotating fixed shaft abuts against the collision part, the first elastic abutment and the second elastic abutment, under elastic action, drive the rotating fixed shaft to slide along the clearance groove until it abuts against the reset part.
[0011] As described above, in a window cleaning machine collision triggering mechanism, the corner wheel fixing member is provided with a first abutting block corresponding to the first switch and a second abutting block corresponding to the second switch.
[0012] As described above, in a window cleaning machine collision triggering mechanism, the first elastic abutment and the second elastic abutment extend upward from the bottom shell of the window cleaning machine and then bend downward to extend respectively between the corner wheel fixing member and the first switch, and between the corner wheel fixing member and the second switch.
[0013] As described above, in a window cleaning machine collision triggering mechanism, the corner wheel fixing member rotates around its axis to press against the first switch or the second switch, and the corner wheel fixing member collapses towards the inside of the bottom shell of the window cleaning machine while simultaneously pressing against the first switch and the second switch, both triggering a collision signal.
[0014] A window cleaning machine, including a window cleaning machine collision triggering mechanism as described in any of the preceding claims.
[0015] Compared with the prior art, this application has the following advantages:
[0016] This application discloses a collision triggering mechanism for a window cleaning machine and the window cleaning machine itself. A rotating fixed shaft is installed in the inner corner area where adjacent sides of the bottom shell of the window cleaning machine intersect. A corner wheel fixing component that can rotate around the shaft is slidably connected to this shaft. This allows the corner wheel fixing component to rotate around the shaft when subjected to forward pressure from an obstacle, and also allows the corner wheel fixing component to slide and displace when subjected to oblique pressure at a 45-degree angle from an obstacle, thereby pressing against the collision switch assembly. This solves the problem in the prior art where the collision switch cannot be triggered due to corner wheel wobbling failure when the window cleaning machine collides with an obstacle at an oblique angle. It ensures that the window cleaning machine can reliably trigger the collision signal under various collision angles, thereby timely detecting collisions, effectively avoiding equipment damage risks and cleaning blind spots, and improving the working reliability and safety of the window cleaning machine.

Detailed Implementation Methods
[0026] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0027] Please see Figures 1 to 8 A collision triggering mechanism for a window cleaning machine includes a bottom shell 1 of the window cleaning machine. A rotating fixed shaft 2 is provided in the inner corner area where adjacent two sides of the bottom shell 1 meet. An angle wheel fixing member 3 is slidably connected to the rotating fixed shaft 2 and can rotate around the rotating fixed shaft 2. An angle wheel 4 is provided on the angle wheel fixing member 3, which is partially protruding outward from the outer contour of the bottom shell 1 of the window cleaning machine. A collision switch assembly 5 is provided on the bottom shell 1 of the window cleaning machine for cooperating with the angle wheel fixing member 3. When the angle wheel 4 is squeezed by an obstacle, the angle wheel fixing member 3 rotates around the shaft or slides to press against the collision switch assembly 5.
[0028] This application discloses a collision triggering mechanism for a window cleaning machine and the window cleaning machine itself. A rotating fixed shaft is installed in the inner corner area where adjacent sides of the bottom shell of the window cleaning machine intersect. A corner wheel fixing component that can rotate around the shaft is slidably connected to this shaft. This allows the corner wheel fixing component to rotate around the shaft when subjected to forward pressure from an obstacle, and also allows the corner wheel fixing component to slide and displace when subjected to oblique pressure at a 45-degree angle from an obstacle, thereby pressing against the collision switch assembly. This solves the problem in the prior art where the collision switch cannot be triggered due to corner wheel wobbling failure when the window cleaning machine collides with an obstacle at an oblique angle. It ensures that the window cleaning machine can reliably trigger the collision signal under various collision angles, thereby timely detecting collisions, effectively avoiding equipment damage risks and cleaning blind spots, and improving the working reliability and safety of the window cleaning machine.
[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the corner wheel fixing member 3 is provided with a relief groove 31 through which the rotating fixing shaft 2 passes. The rotating fixing shaft 2 slides along the relief groove 31 to cause the corner wheel fixing member 3 to collapse inward toward the bottom shell 1 of the window cleaning machine until it presses against the collision switch assembly 5.
[0030] In this embodiment, by setting a corner wheel fixing component with a clearance groove and slidingly engaging with a rotating fixing shaft, the corner wheel can trigger a single-sided switch by rotating around the shaft when subjected to a frontal or oblique collision, and can also trigger a double-sided switch by sliding axially to drive the fixing component to collapse as a whole. This dual triggering mechanism effectively solves the problem of trigger failure during oblique collisions in the prior art.
[0031] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the collision switch assembly 5 includes a first switch 51 disposed on the bottom shell 1 of the window cleaning machine and located on the side of the corner wheel fixing member 3 in the forward rotation direction around the axis, and a second switch 52 located on the side of the corner wheel fixing member 3 in the reverse rotation direction around the axis.
[0032] In this embodiment, by setting a first switch and a second switch on both sides of the rotation direction of the corner wheel fixing component on the bottom shell of the window cleaning machine, the corresponding switch on the corresponding side can be triggered by the corresponding rotation of the corner wheel fixing component regardless of whether the corner wheel is subjected to a collision force from the left or right. Furthermore, when subjected to a positive collision force, the switches on both sides can be triggered by the sliding displacement of the corner wheel fixing component, thus achieving omnidirectional collision detection. This effectively solves the detection blind zone problem existing in the traditional single-switch design. When the corner wheel is subjected to oblique extrusion force, the rotating fixing shaft can slide along the avoidance groove, causing the corner wheel fixing component to move into the bottom shell. At this time, the collision part on the fixing component will simultaneously squeeze the elastic abutments on both sides, thereby triggering the two collision switches, ensuring reliable detection of collisions at any angle. A damping structure can also be set in the avoidance groove to buffer the collision impact.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the bottom shell 1 of the window cleaning machine is provided with a first elastic abutment 61 and a second elastic abutment 62. The first elastic abutment 61 is located between the corner wheel fixing member 3 and the first switch 51, and the second elastic abutment 62 is located between the corner wheel fixing member 3 and the second switch 52. When the corner wheel fixing member 3 rotates around its axis or collapses inward toward the inside of the bottom shell 1 of the window cleaning machine to press against the first elastic abutment 61 and / or the second elastic abutment 62, the first elastic abutment 61 and / or the second elastic abutment 62 deforms and presses against the first switch 51 and / or the second switch 52.
[0034] In this embodiment, by setting a first elastic abutment and a second elastic abutment on the bottom shell of the window cleaning machine between the corner wheel fixing component and the switch, the switch can be smoothly triggered by the buffer deformation of the elastic abutment when the corner wheel fixing component rotates or collapses axially. This design avoids rigid impact between mechanical parts and ensures the reliability and durability of the triggering action. Its working principle is as follows: when the corner wheel fixing component is subjected to an impact force, whether it is rotational displacement or axial collapse, the corresponding elastic abutment will be compressed first. The impact force is converted into a smooth pressing action through the gradual deformation of the elastic body, and finally the corresponding switch signal is triggered. This indirect triggering method can effectively absorb the impact energy to protect the switch structure and eliminate the problem of false triggering caused by mechanical clearance.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the end of the clearance groove 31 near the corner wheel 4 is a collision part 311, and the end away from the corner wheel 4 is a reset part 312. When the rotating fixed shaft 2 slides along the clearance groove 31 to abut against the collision part 311, the corner wheel fixing member 3 simultaneously triggers the first switch 51 and the second switch 52.
[0036] In this embodiment, by providing a collision part and a reset part in the clearance groove, the corner wheel fixing member can completely collapse when subjected to a frontal collision by rotating the fixing shaft along the clearance groove to the collision part, and at the same time triggering the double-sided switch. When the corner wheel is subjected to a frontal collision force, the rotating fixing shaft slides along the clearance groove toward the collision part, causing the corner wheel fixing member to collapse inward as a whole. At this time, the first elastic abutment and the second elastic abutment are squeezed on both sides of the fixing member, so that the two switches are triggered synchronously.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, when the rotating fixed shaft 2 abuts against the collision part 311, the first elastic abutment 61 and the second elastic abutment 62, under elastic action, drive the rotating fixed shaft 2 to slide along the relief groove 31 until it abuts against the reset part 312.
[0038] In this embodiment, the rotating fixed shaft 2 is driven to slide along the clearance groove 31 to the reset part 312 by the elastic action of the first elastic abutment 61 and the second elastic abutment 62. This design realizes the automatic reset function of the equipment and improves the self-recovery capability and operational continuity of the window cleaning machine after a collision. When a collision occurs, the rotating fixed shaft 2 slides to the collision part 311 and triggers the switch. At this time, the elastic abutment stores elastic potential energy during the deformation process. After the collision is resolved, the elastic potential energy is released, pushing the rotating fixed shaft 2 to slide along the clearance groove 31 to the reset part 312, completing the automatic reset of the equipment.
[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the corner wheel fixing member 3 is provided with a first abutting block 321 corresponding to the first switch 51 and a second abutting block 322 corresponding to the second switch 52.
[0040] In this embodiment, the corner wheel fixing member 3 is ensured to accurately press the corresponding switch when rotating, thereby improving the accuracy and reliability of the collision signal triggering. When the corner wheel 4 is squeezed by an obstacle, the corner wheel fixing member 3 will rotate around the rotation fixing axis 2, and the first abutment block 321 or the second abutment block 322 will accurately press the corresponding first switch 51 or the second switch 52, thereby triggering the collision signal and improving the reliability of the device and the user experience.
[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the first elastic abutment 61 and the second elastic abutment 62 extend upward from the bottom shell 1 of the window cleaning machine and then bend downward to extend between the corner wheel fixing member 3 and the first switch 51, and between the corner wheel fixing member 3 and the second switch 52, respectively.
[0042] In this embodiment, by extending the first elastic abutment 61 and the second elastic abutment 62 upward and then bending them downward to extend them between the corner wheel fixing member 3 and the first switch 51 and the second switch 52 respectively, the spatial layout of the elastic abutment is optimized. The bending structure also increases the deformation capability and trigger sensitivity of the elastic abutment. When the corner wheel fixing member 3 is squeezed and displaced, it will first press against the elastic abutment of the bending structure. During the deformation process, the elastic abutment will transmit the pressure to the switch, thereby triggering the collision signal.
[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the corner wheel fixing member 3 rotates around its axis to press against the first switch 51 or the second switch 52, and the corner wheel fixing member 3 collapses towards the inside of the window cleaning machine's bottom shell 1 while simultaneously pressing against the first switch 51 and the second switch 52, both triggering a collision signal.
[0044] In this embodiment, the reliability and safety of the device are improved. When the corner wheel 4 is squeezed by an obstacle, the corner wheel fixing member 3 will displace in two ways: one is to rotate around the rotating fixed axis 2, pressing the corresponding switch through the first abutment block 321 or the second abutment block 322; the other is to slide along the avoidance groove 31 and collapse inward, pressing the two switches through the deformation of the elastic abutment member. Regardless of the method, it ensures that the collision signal is triggered in a timely manner. This design solves the blind spot problem that may exist in a single triggering method, ensuring that collisions under various operating conditions can be fully detected.

[0046] The working principle of this embodiment is as follows:
[0047] This application discloses a collision triggering mechanism for a window cleaning machine and the window cleaning machine itself. A rotating fixed shaft is installed in the inner corner area where adjacent sides of the bottom shell of the window cleaning machine intersect. A corner wheel fixing component that can rotate around the shaft is slidably connected to this shaft. This allows the corner wheel fixing component to rotate around the shaft when subjected to forward pressure from an obstacle, and also allows the corner wheel fixing component to slide and displace when subjected to oblique pressure at a 45-degree angle from an obstacle, thereby pressing against the collision switch assembly. This solves the problem in the prior art where the collision switch cannot be triggered due to corner wheel wobbling failure when the window cleaning machine collides with an obstacle at an oblique angle. It ensures that the window cleaning machine can reliably trigger the collision signal under various collision angles, thereby timely detecting collisions, effectively avoiding equipment damage risks and cleaning blind spots, and improving the working reliability and safety of the window cleaning machine.
