[0030] Further, by moving the unlocking piece (such as pressing or pulling), the clamping assembly can be driven to separate from the clamping interface 31, without the need for tools or complex actions, the user can quickly switch between "self-cleaning" and "manual assistance" modes, which is beneficial to improve the operation convenience.

[0031] Optionally, in some embodiments, the clamping assembly comprises a mounting seat arranged at the end of the operating rod 2, elastic buckles symmetrically hinged on both sides of the mounting seat, and a reset spring sleeved outside the elastic buckles; one end of the elastic buckle away from the mounting seat is provided with an outwardly protruding clamping part, the clamping part is matched with the limiting groove in the inner wall of the clamping interface 31; the unlocking piece 33 is an annular unlocking sleeve sleeved outside the mounting seat, the inner wall of the unlocking sleeve is provided with a guide slope matched with the outer side slope of the elastic buckle; during assembly, the mounting seat of the operating rod 2 is inserted into the clamping interface 31 of the window cleaner body 1, the elastic buckle is pressed inwardly to shrink when the clamping interface 31 is pressed, when the clamping part moves to the limiting groove position, the reset spring pushes the elastic buckle to expand outwardly, the clamping part is clamped into the limiting groove, and fixed connection between the two is realized; when unlocking, the unlocking sleeve is axially pushed, the outer side slope of the elastic buckle is pressed by the guide slope, and the elastic buckle is forced to shrink inwardly against the elastic force of the reset spring, and the clamping part is separated from the limiting groove, at this time the operating rod 2 can be directly pulled out to complete the separation.

[0032] Optionally, in some embodiments, the clamping assembly comprises a sliding hole opened radially along the operating rod 2, a clamping pin slidingly arranged in the sliding hole, and a compression spring having one end connected with the clamping pin and the other end fixed to the bottom of the sliding hole; the outer end of the clamping pin is in a spherical surface structure and is matched with an annular clamping groove in the inner wall of the clamping port 31; the unlocking piece 33 is an unlocking pull rod penetrating axially through the operating rod 2, one end of the unlocking pull rod extends into the sliding hole and is hinged with the inner end of the clamping pin, and the other end extends to the outside of the operating rod 2 and is provided with a pull ring; during assembly, the end portion of the operating rod 2 is inserted into the clamping port 31, the spherical end of the clamping pin is pressed by the inner wall of the clamping port 31, the compression spring is contracted, and the clamping pin is retracted into the sliding hole; when the sliding hole is aligned with the annular clamping groove, the compression spring is reset to push the clamping pin to extend outward, and is clamped into the annular clamping groove to achieve locking; during unlocking, the pull ring is pulled outward, the unlocking pull rod drives the clamping pin to retract into the sliding hole against the elastic force of the compression spring, the clamping pin is disengaged from the annular clamping groove, and the operating rod 2 and the window cleaning machine body 1 can be separated.

[0034] Further, as a preferred manner but not a limitation of the present application, the clamping assembly comprises two oppositely arranged movable clamping blocks 321, a transmission sliding block 322 and two L-shaped transmission connecting rods 323; the two movable clamping blocks 321 are respectively located on the left and right sides of the transmission sliding block 322, one side of each transmission connecting rod 323 is connected to the tail of the corresponding movable clamping block 321, and the other end is connected to the transmission sliding block 322; the transmission sliding block 322 is fixedly connected with the unlocking member 33 and is vertically slidably arranged in the mounting base 21 of the operating rod 2; the front end of each movable clamping block 321 is provided with a clamping hook portion for clamping with the clamping interface 31 on the window cleaning machine body 1; when the unlocking member 33 is pressed upward, the transmission sliding block 322 is driven to move upward synchronously, and through the lever action of the L-shaped transmission connecting rod 323, the front ends of the two movable clamping blocks 321 are horizontally folded inward, the clamping hook portions are separated from the clamping interface 31, and separation is realized; after the unlocking member 33 is released, the transmission sliding block moves downward, the two movable clamping blocks 321 expand outward relative to each other, the clamping hook portions are clamped into the clamping interface 31 again, and connection is completed.

[0035] As shown in Figures 1 to 8 The operating rod 2 comprises a mounting base 21, the clamping assembly is arranged in the mounting base 21, the mounting base 21 is provided with a guide hole 211, the unlocking member 33 passes through the guide hole 211 and is connected with the clamping assembly, and the unlocking member 33 and the guide hole 211 are in sliding fit to drive the clamping assembly to move synchronously; Further, the guide hole 211 rigidly restricts the sliding track of the unlocking member 33, avoids the occurrence of deviation, jamming or tilting of the unlocking member 33 during movement, and is beneficial to ensuring that the unlocking member 33 can accurately transmit driving force to drive the clamping assembly to accurately cooperate with or separate from the clamping interface 31; at the same time, the sliding fit structure can reduce the frictional resistance between the unlocking member 33 and the mounting base 21, so that the disassembly and assembly operation is smoother, and the user's use feeling is improved.

[0036] Specifically, the guide hole 211 is an elongated circular through hole extending in the vertical direction, the length direction of the guide hole 211 is consistent with the moving direction of the unlocking member 33, the guide hole 211 can provide sufficient linear movement stroke for the unlocking member 33, ensure smooth sliding of the unlocking member 33 during pressing or releasing, and drive the clamping assembly to complete clamping and separation actions.

[0037] Further, the mounting base 21 is provided with a positioning bolt 212 near one side of the window cleaning machine body 1, and the window cleaning machine body 1 is provided with a positioning hole 11 in plug fit with the positioning bolt 212; during the connection of the operating rod 2 and the window cleaning machine body 1, the positioning bolt 212 is first inserted into the positioning hole 11 to realize the centering and circumferential positioning of the two in the horizontal direction, which is beneficial to ensuring that the clamping assembly is accurately aligned with the clamping interface 31, thereby improving the connection reliability and assembly smoothness.

[0038] As shown in Figures 1 to 8The shown card joint assembly includes a movable card block 321, a transmission slider 322 and a transmission connecting rod 323. The movable card block 321 is used to cooperate with the card joint 31. The transmission slider 322 is connected with the unlocking piece 33. One side of the transmission connecting rod 323 is connected with the transmission slider 322, and the other side of the transmission connecting rod 323 is connected with the movable card block 321. Further, the unlocking piece 33 moves in the vertical direction, and through the cooperation of the transmission slider 322 and the transmission connecting rod 323, the vertical movement is efficiently converted into the horizontal movement of the movable card block 321, so as to realize the “folding-unfolding” action of the movable card block 321. This direction conversion mechanism can complete the card joint and unlocking without complex mechanical mechanism, and has compact structure and reliable action.

[0039] Further, the transmission connecting rod 323 can be flexibly adjusted in installation position and movement track, compared with the direct driving structure, which is conducive to better adapt to the limited space inside the installation base 21, reasonably arrange the movable card block 321, the transmission slider 322 and the unlocking piece 33, avoid component interference, and help to meet the compact structure design requirement of the window cleaning robot.

[0040] Specifically, the transmission connecting rod 323 has a first connecting rod section extending in the vertical direction and a second connecting rod section extending in the horizontal direction. The first connecting rod section and the second connecting rod section are integrally formed and in “L” shape. When the unlocking piece 33 drives the transmission slider 322 to move in the vertical direction, the transmission slider 322 drives the first connecting rod section to synchronously move in the vertical direction. By means of the corner transmission relationship of the two connecting rod sections, the first connecting rod section converts the driving force in the vertical direction into the horizontal movement of the second connecting rod section, and further drives the movable card block connected with the second connecting rod section to stretch or contract in the horizontal direction, so as to realize the cooperation or separation with the card joint 31.

[0041] As Figures 1 to 8The movable clamping blocks 321 shown include a first movable clamping block 3211 and a second movable clamping block 3212, which are arranged opposite to each other in the horizontal direction, the transmission connecting rods 323 include a first transmission connecting rod 3231 and a second transmission connecting rod 3232, one side of the first transmission connecting rod 3231 is connected to the first movable clamping block 3211, one side of the second transmission connecting rod 3232 is connected to the second movable clamping block 3212, the other side of the first transmission connecting rod 3231 and the other side of the second transmission connecting rod 3232 are both connected to the transmission sliding block 322, the transmission sliding block 322 is arranged in the mounting base 21 and connected to the unlocking piece 33, when the unlocking piece 33 moves in the vertical direction in the guide hole 211, the unlocking piece 33 drives the transmission sliding block 322 to move synchronously in the vertical direction, so that the first transmission connecting rod 3231 and the second transmission connecting rod 3232 drive the first movable clamping block 3211 and the second movable clamping block 3212 to move towards or away from each other in the horizontal direction, respectively. Further, the first movable clamping block 3211 and the second movable clamping block 3212 are arranged opposite to each other in the horizontal direction and are connected to the same transmission sliding block 322 through the respective transmission connecting rods 323, which is beneficial to ensure that the first movable clamping block 3211 and the second movable clamping block 3212 on both sides are strictly synchronized to move towards each other or away from each other during unlocking or locking, avoiding unilateral clamping, partial load or uneven force, making the clamping action stable and well-centered, which helps to improve the reliability and repeated positioning accuracy of the cooperation with the clamping interface 31.

[0042] Further, only one transmission sliding block 322 is needed to drive the first movable clamping block 3211 and the second movable clamping block 3212 on both sides, without the need for independent driving mechanisms, which is beneficial to simplify the internal structure; secondly, all moving parts are integrated in the mounting base 21, which helps to save space and facilitate functional integration at the end of the slender operating rod 2 while keeping the appearance simple.

[0043] Further, the vertical movement of the unlocking piece 33 is evenly distributed to the two transmission connecting rods 323 through the transmission sliding block 322, and then converted into the displacement of the movable clamping blocks 321 in the horizontal direction, the force flow path is short and the friction loss is small, the user has a light and responsive feeling during operation, and it is not easy to cause functional failure due to local wear.

[0044] Preferably, a return spring is provided between the transmission slider 322 and the mounting base 21. One end of the return spring abuts against the inner wall of the mounting base 21, and the other end abuts against the transmission slider 322. The return spring is arranged vertically. When the user moves the unlocking member 33, the unlocking member 33 overcomes the elastic force of the return spring and drives the transmission slider 322 to move upward in the vertical direction. This causes the first transmission link 3231 and the second transmission link 3232 to drive the first movable block 3211 and the second movable block 3212 to close towards each other and disengage from the card interface 31. When the user releases the unlocking member 33, the return spring pushes the transmission slider 322 downward under the action of elastic restoring force. Then, through the first transmission link 3231 and the second transmission link 3232, the first movable block 3211 and the second movable block 3212 are driven to open in opposite directions and re-engage into the card interface 31, thus achieving automatic locking.

[0045] like Figures 1 to 8 A guide mechanism 4 is provided between the mounting base 21 and the transmission slider 322 shown. The guide mechanism 4 is used to guide the transmission slider 322 to slide vertically relative to the mounting base 21. Furthermore, the guide mechanism 4 effectively constrains the movement path of the transmission slider 322 to prevent it from deviating, wobbling or jamming during movement, ensuring that it slides smoothly in a strictly vertical direction, thereby ensuring the consistency and accuracy of the action of the locking component, and avoiding connection failure or unlocking difficulties caused by the misalignment of the transmission slider 322.

[0046] Furthermore, the guide mechanism 4 shares the lateral load of the transmission slider 322 when it is under force, avoiding direct hard contact or wear between the transmission slider 322 and the inner wall of the mounting base 21. This helps to reduce loosening, deformation or functional degradation during long-term use, and effectively improves the durability and reliability of the equipment.

[0047] Optionally, in some embodiments, the guide mechanism 4 includes at least one vertically arranged guide post and a corresponding guide hole. The guide post is fixed to the side wall of the mounting base 21, and the guide hole 44 is opened on the transmission slider 322 and is coaxial with the guide post. After assembly, the guide post passes through the guide hole, and the transmission slider 322 slides up and down along the guide post to achieve vertical guidance.

[0048] Optionally, in some embodiments, the guide mechanism 4 includes a ball bearing sleeve embedded in the transmission slider 322 and a guide shaft fixed in the mounting base 21; the guide shaft is arranged in a vertical direction, the ball bearing sleeve is sleeved on the outer periphery of the guide shaft, and low-friction sliding is achieved through the internal balls.

[0049] Optionally, in some embodiments, the guide mechanism 4 comprises vertical T-shaped slots arranged on the inner wall of the mounting base 21, and T-shaped sliding blocks arranged on the outer side of the transmission sliding block 322; the T-shaped sliding blocks are embedded in the T-shaped slots, and the heads thereof are limited by the slot openings to prevent disengagement.

[0050] Further, as a preferred mode of the present application but not limited, the guide mechanism 4 comprises guide sliding rails 41 arranged on the inner side wall of the mounting base 21, and guide sliding grooves 42 arranged on the outer side wall of the transmission sliding block 322; the guide sliding rails 41 extend in the vertical direction, and the guide sliding grooves 42 are in sliding connection with the guide sliding rails 41; when the transmission sliding block 322 moves under the drive of the unlocking piece 33, the guide sliding grooves 42 slide up and down along the guide sliding rails 41, thereby limiting the transmission sliding block 322 to move only in the vertical direction and preventing it from deflecting or shaking.

[0051] As shown in the Figures 1 to 8 guide mechanism 4 comprises guide sliding rails 41 arranged on the inner side wall of the mounting base 21, and guide sliding grooves 42 arranged on the transmission sliding block 322 and in sliding connection with the guide sliding rails 41; Further, the guide sliding rails 41 and the guide sliding grooves 42 form a sliding pair in surface contact or line contact, which effectively restricts the movement of the transmission sliding block 322 in the vertical direction and effectively prevents it from deflecting, twisting or shaking during movement, thereby ensuring consistent and reliable action of the clamping assembly.

[0052] Optionally, in some embodiments, the guide sliding rails 41 are integrally formed with the mounting base 21, i.e., when the mounting base 21 is injection molded or processed, a protruding structure extending in the vertical direction is directly formed on the inner side wall thereof as the guide sliding rail 41; this structure does not require additional parts, and the manufacturing process is simple, the assembly steps are few, which is conducive to reducing production costs and improving production efficiency.

[0053] Further, as a preferred mode of the present application but not limited, the guide sliding rails 41 are independent parts which are fixed to the inner side wall of the mounting base 21 by buckling, hot melting, screwing or embedding; the guide sliding rails 41 can be made of materials with better wear resistance or self-lubricating properties, while the mounting base 21 can still use conventional engineering plastics, thereby optimizing the performance at the key friction part; at the same time, this structure facilitates later maintenance and replacement, and can improve the guiding accuracy and structural reliability.

[0054] As shown in the Figures 1 to 8 operation lever 2 comprises an inner lever 201 and an outer lever 202, the outer lever 202 is sleeved on the outer side wall of the inner lever 201 and is in sliding connection with the inner lever 201, and a telescopic mechanism 5 is arranged between the inner lever 201 and the outer lever 202; Further, by the relative sliding of the inner rod 201 and the outer rod 202, the overall length of the operating rod 2 can be flexibly adjusted, facilitating the user to extend or retract according to the height of the window, the cleaning position or the height requirement, which is not only suitable for fine operation of low glass, but also meets the remote cleaning of high-level or high-window area, and is beneficial to improve the application range and man-machine efficiency of the equipment.

[0055] Further, the inner rod 201 and the outer rod 202 adopt a sleeve type structure, the contact area of the two is large, the guiding accuracy is high, the radial swing or torsion can be effectively limited, the structural stability of the operating rod 2 in the extension process and the elongated state can be ensured, and the problem of insufficient rigidity caused by length extension can be avoided.

[0056] Optionally, in some embodiments, the telescopic mechanism 5 comprises a plurality of positioning holes arranged on the outer side wall of the inner rod 201 and a elastic clamping convex arranged on the inner side wall of the outer rod 202; the elastic clamping convex is composed of an elastic arm and a convex part, and the convex part faces the surface of the inner rod; during assembly, the outer rod 202 is sleeved on the outer side of the inner rod 201, when the elastic clamping convex slides to a certain positioning hole position, the convex part is automatically embedded in the positioning hole under the restoring force of the elastic arm, and length locking is realized; when the length is adjusted, the elastic clamping convex is pulled out of the positioning hole by applying an axial pushing force or a pulling force, and then is clamped again after sliding to a new position, and the telescopic positioning is completed.

[0057] Optionally, in some embodiments, the telescopic mechanism 5 comprises an outer thread segment arranged on the outer side wall of the inner rod 201 and a locking sleeve arranged at the end of the outer rod 202, the inner wall of the locking sleeve is provided with an inner thread matched with the outer thread segment, and the locking sleeve and the outer rod 202 are connected through an elastic connecting piece (such as a spring washer); during assembly, the outer rod 202 is sleeved on the outer side of the inner rod 201, the locking sleeve is rotated to make it screwed along the thread, the locking sleeve is radially contracted under the action of the axial force, the inner rod 201 is clamped, and fixing is realized; when loosening, the locking sleeve 54 is rotated in the opposite direction, the clamping force is released, and the length can be adjusted.

[0058] Optionally, in some embodiments, the telescopic mechanism 5 comprises a high-friction layer arranged on the outer side wall of the inner rod 201 and an elastic clamping ring arranged on the inner side wall of the outer rod 202; the high-friction layer is made of rubber, silicone or high-friction coefficient plastic, and the elastic clamping ring is integrally formed on the inner wall of the outer rod 202 by an elastic material; after assembly, the elastic clamping ring is always in close contact with the high-friction layer, and the current length is maintained through the friction force; the user can overcome the friction force by applying sufficient axial force to slide and adjust, and the length is automatically locked after loosening, realizing stepless telescopic.

[0059] As Figures 1 to 8The telescopic mechanism 5 shown includes a limiting protrusion 51 disposed on the inner side wall of the outer rod 202 and a limiting seat 52 disposed on the inner rod 201. The limiting seat 52 is provided with a limiting part 521. The limiting protrusion 51 extends toward the outer side wall of the inner rod 201 and abuts against the limiting part 521. Furthermore, after the limiting protrusion 51 abuts against the limiting part 521 of the limiting seat 52, it limits the maximum stretching stroke of the outer rod 202 relative to the inner rod 201, so as to prevent the user from causing the outer rod 202 to detach from the inner rod 201 due to excessive stretching during use, resulting in the failure of the operating lever 2 or the loss of parts.

[0060] Furthermore, the limiting protrusion 51 can be directly formed on the inner wall of the outer rod 202, and the limiting seat 52 can be a local boss, annular block or independent insert on the inner rod 201. Neither of these will significantly increase the outer diameter of the rod or affect the internal space.

[0061] Specifically, the limiting protrusion 51 is an arc-shaped protrusion structure integrally formed on the inner side wall of the outer rod 202. It extends from the inner wall of the outer rod 202 toward the inner rod 201 and has a smooth arc surface. It can smoothly pass through the transition area during relative sliding with the inner rod 201, and reliably abut against the limiting part 521 of the limiting seat 52 when it reaches the limiting position, thereby achieving axial stop and preventing the outer rod 202 from completely detaching from the inner rod 201.

[0062] Furthermore, the limiting seat 52 is an independent component installed on the inner rod 201. Its cross-section is "T" shaped. The limiting seat 52 has a mounting arm extending in the vertical direction and a limiting arm extending in the horizontal direction. The limiting part 521 is provided on the lower surface of the limiting arm. The inner side wall of the inner rod 201 is provided with a locking protrusion 2011 to restrict the axial movement of the limiting seat 52. The locking protrusion 2011 abuts against the end or side wall of the mounting arm, reliably fixing the limiting seat 52 to the predetermined position of the inner rod 201, ensuring that it remains stable during the extension and retraction process, and effectively cooperating with the limiting protrusion 51 on the outer rod 202 to achieve the anti-disengagement function.

[0063] like Figures 1 to 8 The control lever 2 shown is equipped with a button 22, which is signal-connected to the window cleaning machine body 1; Furthermore, while holding the operating lever 2, the user can send control commands (such as start / stop, mode switching, direction adjustment, etc.) to the window cleaning machine body 1 by pressing the button 22. Even when the window cleaning machine body 1 is separated from the operating lever 2, it can be controlled in real time, effectively making up for the shortcomings of the fully automatic mode in dealing with emergencies.

[0064] Further, the key 22 is integrated in the operation rod area, which is ergonomic, and the user can complete the control operation with one hand during the cleaning process without an additional remote controller or bending down to touch the window cleaning machine body 1, which is beneficial to improve the use convenience and operation fluency.

[0065] Optionally, in some embodiments, the key 22 is electrically connected to a Bluetooth module arranged inside the operation rod 2, and the window cleaning machine body 1 is provided with a corresponding Bluetooth receiving module and a main control unit; when the user presses the key 22, the Bluetooth module encodes the corresponding control signal (such as a start or pause instruction) and sends it to the window cleaning machine body 1 in a wireless manner, and the main control unit executes the corresponding operation after receiving the signal.

[0066] Optionally, in some embodiments, the operation rod 2 is provided with a radio frequency transmitting circuit inside, and the output end of the key 22 is connected to the circuit; the window cleaning machine body 1 is provided with a matching radio frequency receiving circuit; each key 22 corresponds to a different coded signal, and when pressed, the radio frequency transmitting circuit sends a wireless signal of a specific frequency or code, and the window cleaning machine body 1 decodes and executes the corresponding instruction.

[0067] Optionally, in some embodiments, the operation rod 2 is provided with a Wi-Fi communication module inside, and the key 22 is electrically connected to the Wi-Fi communication module; the window cleaning machine body 1 is provided with a corresponding Wi-Fi transceiver unit and a main controller; when the user presses the key 22, the Wi-Fi communication module encodes the control instruction and sends it to the window cleaning machine body 1 through the Wi-Fi signal, and the main controller receives and analyzes the instruction and then executes the corresponding operation.

[0068] The above is only to further illustrate the technical content of the present application by way of examples, so that the reader can more easily understand, but it does not mean that the embodiments of the present application are limited to this, any technical extension or re-creation made according to the present application is also protected by the present application.
