Fig. 1 shows an exploded view of a self-propelled device according to an embodiment of the present invention. As shown in fig. 1, in some embodiments, the self-walking device includes a body 11, a walking module 12, a pumping module 13, and a plurality of air pressure sensors 14. The walking modules 12 are disposed on two corresponding sides of the main body 11, and the air-extracting module 13 and the air pressure sensor 14 are disposed on the main body 11.
In some embodiments, the self-propelled device is adapted to be attached to a board (not shown) and moved across the surface of the board using the travel module 12 to clean the surface of the board of dirt or stains. In some embodiments, the panel may be an upright window. As illustrated in fig. 1, the walking module 12 may include a walking assembly 121 and a walking assembly 122, which may be a pulley, a roller, or the like capable of moving to drive the self-walking device to move forward, backward or turn on the surface of the board. In the embodiment shown, the running assemblies 121 and 122 are pulleys, including a track and two drive wheels driving the track.
In order to realize that the self-walking device can move on a plate body which is not horizontally arranged without falling off, the utility model utilizes the combination of the body 11 and the air extraction module 13 to achieve the purpose of adsorbing the surface of the plate body. Specifically, in some embodiments, the body 11 includes the suction cup 20 and the carrier plate 30, and the body 11 can be constructed by stacking the suction cup 20 and the carrier plate 30 on top of each other, such that the carrier plate 30 is close to the upper portion of the body 11 and the suction cup 20 is close to the lower portion of the body 11. In some embodiments, the walking module 12 may be connected to the body 11, and more specifically, the walking module 12 may be disposed inside the body 11 or directly against the body 11. In some embodiments, the walking module 12 may be adjacent to both sides of the suction cup 20. The air pumping module 13 is disposed on the carrier plate 30, and pumps air from the carrier plate 30 to the air pumping module 13, so that air near the surface of the board can be pumped out from the surface of the board through the suction cup 20 and the carrier plate and the air pumping module, and negative pressure exists between the self-walking device and the surface of the board, thereby generating an acting force through atmospheric pressure on the self-walking device, and enabling the self-walking device to be adsorbed on the surface of the board. In one embodiment, the pumping module 13 comprises a pump.
In detail, the present invention can form a negative pressure space between the surface of the plate body, the body 11 and the air extraction module 13, so that the self-walking device can move on the plate body which is not horizontally arranged without falling. In some embodiments, the space for generating the negative pressure may be further divided into a first space and a second space defined by the body 11, and the first space is communicated with the second space. Specifically, the first space and the second space are divided by the structures of the suction cup 20 and the carrier plate 30.
In one embodiment, the plurality of air pressure sensors 14 are used for measuring the air pressure in the self-propelled device, and in one embodiment, the air pressure in the first space and the air pressure in the second space are respectively measured, and the air pressure can measure the state of the negative pressure generated by the air suction through the air suction module 13, so that when the state of the negative pressure changes, whether the sealing performance of the first space and the second space has changed or not can be judged.
In some embodiments, the self-walking device includes a housing 15 having a receiving space therein for receiving the body 11, the walking module 12, the air-extracting module 13 and the plurality of air pressure sensors 14. In some embodiments, the self-propelled device includes a spraying module (not shown) that can be embedded in the housing 15, or can be attached or adhered to the housing 15, for spraying a cleaning liquid such as water or detergent.
In some embodiments, the self-propelled device includes a cleaning cloth 60 that is adhered to the second surface 20B (see FIG. 2B later) of the suction cup 20 and is configured to contact the surface of the board body. In some embodiments, the cleaning cloth 60 has wool fibers for cleaning on its outer surface and an elastic plastic sheet as its inner liner structure on its inside, thus having a shielding effect of blocking the passage of air in addition to the first cleaning cloth openings 601 and the plurality of second cleaning cloth openings 602 it has.
Reference is also made to the exploded perspective view of fig. 1 and the perspective views of the suction cup shown in fig. 2A and 2B, wherein fig. 2A and 2B are views of the suction cup 20 from the upper side and the lower side, respectively, near the suction cup. In some embodiments, the suction cup 20 has a first surface (upper surface) 20A and a corresponding second surface (lower surface) 20B, and the suction cup 20 includes a sealing structure on the first surface 20A for forming a first space and a sidewall of a second space portion. In some embodiments, the suction cup 20 includes a first suction cup wall 21 protruding from the first surface 20A and a plurality of second suction cup walls 22 on the first surface 20A, wherein the first suction cup wall 21 is located at the center of the suction cup 20 and serves as a portion of the first space therein; the second suction cup wall portions 22 are respectively adjacent to the edges of the suction cups 20, and the interior thereof serves as a portion of the second space. In some embodiments, the suction cup 20 has an appearance similar to an English letter H-shaped structure, so that the four second suction cup wall portions 22 are respectively located at the four branches of the structure from which the suction cup 20 extends. In some embodiments, the volume of the second space is less than the volume of the first space. In some embodiments, the second surface 20B of the suction cup 20 includes a recessed area 202 near the center of the second surface 20B of the suction cup 20. In some embodiments, the recessed area 202 has a plurality of ribs 203 therein to enhance the structural rigidity of the suction cup 20.
Referring again to fig. 1, in some embodiments, the carrier plate 30 disposed on the suction cup 20 has a carrier plate wall 31 located at the center of the carrier plate 30 for engaging with the first suction cup wall 21 to form a closed structure, and the carrier plate wall 31 can still move relative to the first suction cup wall 21. In some embodiments, the carrier plate 30 has a first carrier plate through hole 310. In some embodiments, the first carrier plate through hole 310 is defined by a carrier plate wall 31, for example, the carrier plate wall 31 surrounds the first carrier plate through hole 310. In some embodiments, the first suction cup through hole 210A is defined by the first suction cup wall 21, for example, the first suction cup wall 21 surrounds the first suction cup through hole 210A. In some embodiments, the area defined by the first suction cup wall portion 21 is the first suction cup through hole 210A before being sealed, and is the first space or at least a portion thereof after being sealed. The first suction cup through hole 210A may have an arc-shaped opening (as shown in FIG. 1) or a circular opening (as shown in the first suction cup through hole 210B of FIG. 2B). For example, the carrier plate wall 31 may have a protrusion 311 on a surface facing away from the suction cup 20, and a corresponding groove 312 (as shown in fig. 3A or 3B) on a surface facing the suction cup 20 of the carrier plate 30, allowing the first suction cup wall 21 to be inserted into the groove 312. In some embodiments, the body 11 may include at least one pivot shaft (not shown) for limiting the vertical movement direction of the carrier 30 and the suction cup 20 after being engaged, so that the thickness variation of the self-walking device can be maintained to a certain extent in the vertical direction without separating the carrier 30 and the suction cup 20. For example, the pivot shaft may be located near the corner of the suction cup 20 and fixed to the suction cup to extend toward the carrier 30. The carrier plate 30 is movably connected to the suction cup 20 by a pivot shaft. During the above-mentioned thickness increase or decrease process of the self-walking device, the volume of the first space is increased or decreased correspondingly.
More specifically, in some embodiments, the carrier 30 has a plurality of through holes, and the pivot shaft passes through the through holes. The length of the pivot shaft is greater than the length of the corresponding through hole, so that the suction cup 20 can be pivoted to the support plate 30 by the pivot shaft, and the suction cup 20 can move along the long axis of the pivot shaft. Thus, the suction cup 20 can move relative to the carrier 30 through the pivot shaft and can be driven by the carrier 30. Preferably, the long axis of the pivot shaft is substantially parallel to the normal direction perpendicular to the bottom surface of the suction cup 20, so that the suction cup 20 can move in the normal direction.
The protrusion 311 of the carrier plate wall 31 forms a receiving space for receiving the pumping module 13, and the groove 312 of the carrier plate wall 31 and the first suction cup wall 21 are connected to each other. Fig. 3A illustrates a perspective view of the suction cup 20 and carrier plate 30 according to some embodiments of the present invention. Fig. 3B illustrates a cross-sectional view of a portion along line AA of the combination of the chuck 20 and the carrier plate 30 of the embodiment of fig. 3A. Referring to fig. 3A and 3B, the groove portion 312 includes a first groove wall 411, a second groove wall 412, and a groove 413 located between the first groove wall 411 and the second groove wall 412. The first suction cup wall 21 includes a first outer wall 211, a second inner wall 212, and a concave space 213 between the first outer wall 211 and the second inner wall 212. When the groove portion 312 of the carrier plate wall portion 31 and the first suction cup wall portion 21 are engaged with each other, the first outer wall 211 is located in the groove 413, such that the first outer wall 211 is located between the first groove wall 411 and the second groove wall 412, and moves up and down along the first groove wall 411 and the second groove wall 412; and the second groove wall 412 is located in the recessed space 213, such that the second groove wall 412 is located between the first outer wall 211 and the second inner wall 212, and moves up and down along the first outer wall 211 and the second inner wall 212.
According to this embodiment, the gas air needs to enter the groove 413, then enter the recess space 213, and finally enter the first chamber. More specifically, the path of the gas air enters the groove 413 and then flows out of the groove 413, the path of the gas air is U-shaped, the path of the gas air enters the concave space 213 and then flows out of the concave space 213, the path of the gas air is inverted U-shaped, and the path of the gas air makes at least one turn, preferably a 180-degree turn, so that the air is less likely to flow into the first space. In addition, since the first outer wall 211 and the first groove wall 411; and the first outer wall 211 and the second groove wall 412 are close to each other, and the second groove wall 412 and the first outer wall 211; and the second groove wall 412 and the second inner wall 212 are close to each other, so that the air is not easy to flow into the first space, and the air leakage of the first space can be further prevented. In one embodiment, the path of the gas air makes only one turn. For example, the surface of the carrier 30 facing the chuck 20 may have a groove 312, and the groove 312 has a groove 413, allowing the first outer wall 211 or the second inner wall 212 to be inserted into the groove 413, so that the path of the gas air is U-shaped or inverted U-shaped.
The foregoing outlines structures of several embodiments so that those skilled in the art may better understand the aspects of the present disclosure. Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other manufacturing processes and structures for carrying out the same purposes and/or achieving the same advantages of the embodiments introduced herein. Those skilled in the art should also realize that such equivalent constructions do not depart from the spirit and scope of the present disclosure, and that they may make various changes, substitutions, and alterations herein without departing from the spirit and scope of the present disclosure.
