Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, specifically to an adsorption component pushing mechanism and a cleaning robot. Background Technology

[0002] For cleaning robots capable of cleaning high-rise glass curtain walls, during operation, the suction devices on the robot's moving rods adhere to the glass curtain wall to secure the robot and achieve stable operation. However, in actual operation, cleaning robots generally need to perform continuous cleaning work on glass curtain walls, which requires the robot to climb and move on the glass curtain wall. Therefore, technically, it is often designed with multiple sets of moving rods that move alternately to achieve the robot's climbing and movement.

[0003] When one of the moving rods needs to move, the suction device on it must first be raised or lifted to detach from the opening wall glass so that the moving rod can move normally. Currently, the structure on the moving rods of existing cleaning robots used to raise or lift the suction device is generally a linear slide rail structure (such as a gear and rack moving slide rail structure). The linear slide rail structure must be raised by the same distance as the suction device. This inevitably causes structural and kinematic interference between these linear slide rail structures and other parts of the cleaning robot in some cases, such as kinematic interference with the cleaning head, affecting normal operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, one of the objectives of this invention is to propose an adsorption component pushing mechanism that can lift or raise the adsorption component without interfering with other components of the cleaning robot, thus ensuring operational efficiency.

[0005] The technical solution of this utility model is implemented as follows: An adsorption component pushing mechanism is provided, which is installed between an adsorption component and a moving rod. The adsorption component pushing mechanism includes a folding assembly and a driving component. One end of the folding assembly is installed on the moving rod, and the other end of the folding assembly is installed on the adsorption component. The driving component is installed on the moving rod and configured to drive the folding assembly to perform an unfolding action or a folding action. When the folding assembly unfolds, the adsorption component moves away from the moving rod, and when the folding assembly folds, the adsorption component moves closer to the moving rod.

[0006] Preferably, the folding assembly includes a first folding member and a second folding member, which are arranged opposite to each other, that is, the opening directions of the first folding member and the second folding member when unfolded are opposite to each other, i.e., the first folding member and the second folding member are mirror images of each other; one end of the first folding member is rotatably mounted to the moving rod, and the other end is rotatably mounted to the suction member; one end of the second folding member is rotatably mounted to the moving rod, and the other end is rotatably mounted to the suction member; the driving member is connected to the first folding member or the second folding member, and when the driving member drives one of the folding members to perform an unfolding or folding action, the other folding member simultaneously performs an unfolding or folding action, that is, when the driving member drives one of the folding members to perform an unfolding action, the other folding member also simultaneously performs an unfolding action, and when the driving member drives one of the folding members to perform a folding action, the other folding member also simultaneously performs a folding action.

[0015] Compared with the prior art, the present invention has the following advantages: The suction push mechanism uses the folding action of its folding component to bring the suction component closer to the moving rod, thereby achieving the purpose of lifting or raising the suction component.

This achieves the purpose of not interfering with the normal operation of other parts of the cleaning robot during the lifting of the suction component, thus ensuring work efficiency.

[0022] See Figures 1 to 3An adsorption component pushing mechanism is provided, which is installed between an adsorption component 3 and a moving rod 4. The mechanism includes a folding assembly 1 and a driving component. One end of the folding assembly 1 is installed on the moving rod 4, and the other end is installed on the adsorption component 3. The driving component is installed on the moving rod 4 and configured to drive the folding assembly 1 to perform an unfolding or folding action. When the folding assembly 1 unfolds, the adsorption component 3 moves away from the moving rod 4. In actual operation, the adsorption component 3 is lowered to the glass curtain wall and adsorbed onto it. When the folding assembly 1 folds, the adsorption component 3 moves closer to the moving rod 4. In actual operation, the adsorption component 3 is lifted and moves away from the glass curtain wall. During this lifting process, the folding component 1 folds, which reduces the structural space of the adsorption component pushing mechanism in the lifting direction. In other words, this embodiment achieves the purpose of lifting the adsorption component 3 by reducing the space occupied by the adsorption component pushing mechanism through folding. This avoids the problem of the adsorption component pushing mechanism protruding as it follows the lifting movement of the adsorption component 3, and thus achieves the purpose of not interfering with the normal operation of other parts of the cleaning robot during the lifting of the adsorption component 3, ensuring the working efficiency of the cleaning robot.

[0023] Preferably, the folding assembly 1 includes a first folding member 101 and a second folding member 102. The first folding member 101 and the second folding member 102 are arranged opposite to each other, that is, the opening directions of the first folding member 101 and the second folding member 102 when unfolded are opposite to each other, that is, the first folding member 101 and the second folding member 102 are mirror images of each other. More specifically, in this embodiment, the unfolding range and folding range of the first folding member 101 and the second folding member 102 are the same. In practical applications, the dimensions of their main structures can be designed to be the same. One end of the first folding member 101 is rotatably mounted on... The movable rod 4 is rotatably mounted on the suction element 3 at one end; one end of the second folding element 102 is rotatably mounted on the movable rod 4, and the other end is rotatably mounted on the suction element 3; the driving element is connected to the first folding element 101 or the second folding element 102. When the driving element drives one of the folding elements to perform an unfolding or folding action, the other folding element simultaneously performs an unfolding or folding action. That is, when the driving element drives one of the folding elements to perform an unfolding action, the other folding element also simultaneously performs an unfolding action of the same magnitude. When the driving element drives one of the folding elements to perform a folding action, the other folding element also simultaneously performs a folding action of the same magnitude.

[0024] In a preferred embodiment, the first folding member 101 includes a first main arm 1011, the first end of which is rotatably mounted on the moving rod 4; the second folding member 102 includes a second main arm 1021, the first end of which is rotatably mounted on the moving rod 4; a first semi-circular gear 1013 is mounted on the first end of the first main arm 1011, and a second semi-circular gear 1023 is mounted on the first end of the second main arm 1021; the first semi-circular gear 1013 and the second semi-circular gear 1023 are meshed together, and the first semi-circular gear 1013 and the second semi-circular gear 1023 are connected by the first semi-circular gear 1013 and the second semi-circular gear 1023. The meshing arrangement of the wheels 1023 allows the first folding member 101 and the second folding member 102 to perform unfolding or folding actions synchronously and with the same amplitude. Furthermore, the two symmetrically arranged first folding members 101 and second folding members 102 can stably push or retract the adsorption member 3 when performing synchronous opening and closing actions with the same amplitude, maintaining the adsorption member 3 in a straight line when it is raised or lowered, so as to avoid the problem of uncertain movement trajectory of the adsorption member 3 when it is raised or lowered, thereby improving the structural operational stability of the adsorption member pushing mechanism.

[0025] Preferably, the first folding member 101 further includes a first auxiliary arm 1012. The first end of the first auxiliary arm 1012 is rotatably mounted on the adsorption member 3. The second end of the first main arm 1011 is hinged to the second end of the first auxiliary arm 1012. The first auxiliary arm 1012 and the first main arm 1011 achieve the purpose of the first folding member 101 being able to perform folding and unfolding actions through mutual rotation.

[0026] Further, see Figure 2 and Figure 3 The first main arm 1011 has a first inclined groove 1014 extending to the second end. The first inclined groove 1014 is used to accommodate the first auxiliary arm 1012. The second end of the first auxiliary arm 1012 is hinged to the second end of the first main arm 1011 through the first inclined groove 1014. In this way, the accommodating function of the first inclined groove 1014 on the second end of the first auxiliary arm 1012 helps to improve the structural compactness when the first auxiliary arm 1012 and the first main arm 1011 are folded together. This can further reduce the space occupied by the first folding member after folding, thereby achieving the purpose of expanding the lifting or lowering range of motion of the adsorption member 3.

[0027] Further, see Figure 2The second folding component 102 also includes a second auxiliary arm 1022. The first end of the second auxiliary arm 1022 is rotatably mounted on the adsorption component 3. The second end of the second main arm 1021 is hinged to the second end of the second auxiliary arm 1022. The second main arm 1021 and the second auxiliary arm 1022 achieve the purpose of folding and unfolding the second folding component 102 through mutual rotation. Combined with the folding and unfolding of the first folding component 101, the folding assembly 1 can perform folding and unfolding actions to achieve the purpose of lifting or lowering the adsorption component 3.

[0028] As a preferred embodiment, see [link to previous section]. Figure 2 and Figure 3 The second main arm 1021 has a second inclined groove 1024 extending to the second end. The second inclined groove 1024 is used to accommodate the second auxiliary arm 1022. The second end of the second auxiliary arm 1022 is hinged to the second end of the second main arm 1021 through the second inclined groove 1024. In this way, the accommodating function of the second inclined groove 1024 on the second end of the second auxiliary arm 1022 helps to improve the structural compactness of the second auxiliary arm 1022 and the second main arm 1021 when folded, so as to further reduce the space occupied by the second folding member 102 after folding, thereby expanding the lifting or lowering range of the adsorption member 3. Combined with the same functional effect of the first folding member 101, the overall obstacle-crossing ability of the cleaning robot is improved.

[0029] Preferably, the adsorption component 3 is provided with a hinge seat 301. The first end of the first auxiliary arm 1012 and the first end of the second auxiliary arm 1022 are both coaxially mounted on the hinge seat 301 via a rotating shaft. Mounting the first end of the first auxiliary arm 1011 and the first end of the second auxiliary arm 1021 on the hinge seat 301 of the adsorption component 3 in a coaxial manner is beneficial to improving the structural compactness of the adsorption component 3.

[0030] Preferably, in this embodiment, the driving component includes a motor 2, and a fixing member 5 is provided on the moving rod 4. The motor 2 is mounted on one side of the fixing member 5. The first main arm 1011 and the second main arm 1021 are both rotatably mounted on the other side of the fixing member 5. The output shaft of the motor 2 passes through the fixing member 5 and is connected to the first main arm 1011. That is, in this embodiment, the output shaft of the motor 2 is connected to the first end of the first main arm 1011 to drive the first main arm 1011 to rotate, thereby driving the first folding member 101 and the second folding member 102 to perform unfolding or folding actions. In addition, it should be noted that the specific structure of how the first main arm 1011 and the second main arm 1021 are rotatably mounted on the fixing member 5 can be in the form of bearing seat mounting. Bearing mounting is a conventional technical means and will not be described in detail here. Similarly, the fixed assembly and installation method between the output shaft of the motor 2 and the first main arm 1011 can be a common coupling mounting method, and the specific structure will not be shown or described here either.

[0031] Another objective of this utility model is to provide a cleaning robot, which includes the aforementioned suction component pushing mechanism. By designing the suction component pushing mechanism between the moving rod 4 and the suction component 3, the suction component pushing mechanism will not interfere with other parts of the cleaning robot during the lifting or lowering of the suction component 3, thereby improving the working efficiency of the cleaning robot. The first inclined groove 1014 and the second inclined groove 1024 can also improve the structural compactness of the folding component 1 after folding, and also help to increase the lifting distance of the suction component 3, thereby better improving the overall obstacle-crossing ability of the cleaning robot.

[0032] In summary, the adsorption component pushing mechanism described in this embodiment achieves the purpose of lifting or raising the adsorption component by bringing the adsorption component closer to the moving rod when its folding component performs a folding action. At the same time, the folding component reduces the space in the lifting direction of the adsorption component, so that the adsorption component pushing mechanism will not rise accordingly with the lifting movement of the adsorption component. This achieves the purpose of not interfering with the normal operation of other parts of the cleaning robot during the lifting of the adsorption component, thus ensuring work efficiency.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
