[0036] Combine the following Figures 1 to 5 A cleaning chassis assembly and a cleaning robot provided by the present invention are described. It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any particular limitation to the present invention.

[0037] An embodiment of the first aspect of the present invention provides a cleaning chassis assembly, referring to Figure 1 and Figure 2 As shown, the cleaning chassis assembly includes:

[0038] Chassis body 100;

[0039] A middle sweep opening 200 , the middle sweep opening 200 is arranged to the chassis body 100 ;

[0040] The side sweeping mechanism 300 includes a side brush device 310 and a connecting device 320. The side brush device 310 is connected to the chassis body 100 through the connecting device 320, and the side brush device 310 extends obliquely from the outer side of the chassis body 100 to the position of the middle sweeping opening 200 to collect the edge garbage to the middle sweeping opening 200.

[0041] In the cleaning chassis assembly provided by the present invention, a chassis body 100, a middle sweep opening 200 and a side sweep mechanism 300 are included. Among them, the middle sweep opening 200 is arranged at the middle position of the chassis body 100. The side sweep mechanism 300 includes a side sweep device 310 and a connecting device 320. The side sweep device 310 is connected to the bottom of the chassis body 100 through the connecting device 320, and the side sweep device 310 extends obliquely from the outer side of the chassis body 100 to the position of the middle sweep opening 200. The middle sweep opening 200 is the middle sweep garbage cleaning port of the middle sweep mechanism of the sweeping robot. During operation, when the sweeping robot moves along a preset path, the side brush device 310 on the chassis body 100 can gradually gather the corner garbage to the middle sweep opening 200 during the movement, so that it can be sucked into the interior of the sweeping robot under the action of the garbage suction device.

[0042] With this structural setting, the side brush device 310 is connected to the bottom of the chassis body 100 through the connecting device 320, and the side brush device 310 is extended obliquely from the outside of the chassis body 100 to the position of the middle sweeping opening 200. When the sweeping robot moves along the preset path, the side brush device 310 can gradually collect the corner garbage to the position of the middle sweeping opening 200, so that the corner garbage is removed by the middle sweeping opening 200. In the cleaning chassis assembly, there is no need to separately equip the side sweeping device 310 with an electric drive mechanism, and its cost and failure rate are both low.

[0043] In addition, during the garbage cleaning process, the side sweeping mechanism does not need to perform rotational cleaning, which can effectively avoid the phenomenon of garbage being blown away by the side brush, and the garbage cleaning effect is better. At the same time, the side sweeping mechanism does not need to be equipped with a motor or other driving parts, which can greatly reduce the internal space of the sweeping shell occupied by it.

[0044] In one embodiment of the present invention, the cleaning chassis assembly further includes a pair of running wheels 400. The running wheels 400 are mounted on the chassis body 100. The middle sweeping opening 200 is located between the pair of running wheels 400.

[0045] For example, Figure 1 As shown, the middle sweep opening 200 is located in the middle of the chassis body 100. Two running wheels 400 are respectively arranged on both sides of the middle sweep opening 200. The sweeping robot also includes a shell 500. The chassis body 100 is mounted to the bottom of the shell 500. A garbage suction device and a garbage storage box are arranged inside the shell 500. The inlet of the garbage suction device is arranged corresponding to the middle sweep opening 200, and the outlet of the garbage suction device is arranged corresponding to the garbage storage box, so as to suck the garbage at the middle sweep opening 200 into the garbage storage box.

[0046] In one embodiment of the present invention, the connecting device 320 includes a connecting shaft 321 and a magnetic damping structure 322. One end of the magnetic damping structure 322 is connected to the bottom of the chassis body 100. The other end of the magnetic damping structure 322 is rotatably connected to one end of the connecting shaft 321. The other end of the connecting shaft 321 is connected to the side brush device 310. The magnetic damping structure 322 is used to drive the connecting shaft 321 to limit rotation and automatically return to the center.

[0047] More specifically, in one embodiment of the present invention, the magnetic damping structure 322 includes a first magnetic component, a second magnetic component and a mounting shell 327 .

[0048] The upper end of the mounting shell 327 is connected to the chassis body 100, the first magnetic component is mounted inside the mounting shell 327, and the upper end of the connecting shaft 321 is passed through the inside of the mounting shell 327 and is rotatably connected to the mounting shell 327. The upper end of the connecting shaft 321 is mounted with a second magnetic component, and the magnetic poles of the first magnetic component and the second magnetic component are arranged relative to each other so that a mutual repulsion force is generated between the first magnetic component and the second magnetic component.

[0049] For example, Figures 1 to 4 As shown, the connecting device 320 includes a connecting shaft 321 and a magnetic damping structure 322. The magnetic damping structure 322 includes a mounting shell 327, a first magnetic component and a second magnetic component. Among them, the upper end of the mounting shell 327 is connected to the bottom of the chassis body 100, and the lower end of the mounting shell 327 is provided with a mounting hole for movably mounting the connecting shaft 321. A limiting portion is provided at the upper end of the connecting shaft 321. The upper end of the connecting shaft 321 passes through the mounting hole and extends into the inner cavity of the mounting shell 327, and the limiting portion at the upper end of the connecting shaft 321 is limited to the inner cavity of the mounting shell 327. In other words, after the connecting shaft 321 is movably passed through and limited to the inner cavity of the mounting shell 327, it can rotate relative to the mounting shell 327 to drive the side brush device 310 to adjust the angle, but it cannot move up and down.

[0050] The first magnetic component is mounted on the inner wall of the mounting housing 327. The second magnetic component is mounted on the limit portion of the upper end of the connecting shaft 321. The magnetic poles of the first magnetic component and the second magnetic component are arranged opposite to each other so that the first magnetic component and the second magnetic component can generate mutual repulsion.

[0051] Under normal conditions, the first magnetic component and the second magnetic component reach a mutually exclusive balance, so that the connecting shaft 321 drives the side brush device 310 to maintain a certain balanced tilted state. When the sweeping robot moves forward, the side brush device 310 can collect the corner garbage to the position of the middle sweeping opening 200. When the side brush device 310 encounters an obstacle, the obstacle resistance it encounters will drive the connecting shaft 321 to overcome the mutual exclusive force and rotate to cross the obstacle. After the side brush device 310 crosses the obstacle, it returns to the original balanced tilted state under the action of the mutual exclusive force of the first magnetic component and the second magnetic component.

[0052] In one embodiment of the present invention, the first magnetic assembly includes a first magnet 323 and a second magnet 324. The second magnetic assembly includes a third magnet 325 and a fourth magnet 326.

[0053] The first magnet 323 and the second magnet 324 are connected to the inner wall of the mounting housing 327 at intervals. The third magnet 325 and the fourth magnet 326 are connected to the connecting shaft 321 at intervals. The third magnet 325 and the fourth magnet 326 are located between the two sides of the first magnet 323 and the second magnet 324, respectively.

[0054] Further, in one embodiment of the present invention, the N pole of the first magnet 323 is arranged opposite to the N pole of the third magnet 325. The S pole of the first magnet 323 is arranged opposite to the S pole of the fourth magnet 326. The N pole of the second magnet 324 is arranged opposite to the N pole of the fourth magnet 326. The S pole of the second magnet 324 is arranged opposite to the S pole of the third magnet 325.

[0055] Specifically, if Figure 4 As shown, the first magnetic assembly includes a first magnet 323 and a second magnet 324. The second magnetic assembly includes a third magnet 325 and a fourth magnet 326. For example, the mounting housing 327 is coaxially arranged with the connecting shaft 321. The first magnet 323 and the second magnet 324 are symmetrically arranged on the inner side wall of the mounting housing 327 with the central axis of the mounting housing 327 as the symmetry axis. The third magnet 325 and the fourth magnet 326 are symmetrically arranged on the side wall of the limiter of the connecting shaft 321 with the central axis of the connecting shaft 321 as the symmetry axis. And the line between the first magnet 323 and the second magnet 324 is perpendicular to the line between the third magnet 325 and the fourth magnet 326. Alternatively, the first magnet 323 includes a first side and a second side, and the second magnet 324 also includes a first side and a second side. The first side of the first magnet 323 and the first side of the second magnet 324 are arranged opposite to each other, and the second side of the first magnet 323 and the second side of the second magnet 324 are arranged opposite to each other. The third magnet 325 is disposed between the first side of the first magnet 323 and the first side of the second magnet 324 , and the fourth magnet 326 is disposed between the second side of the first magnet 323 and the second side of the second magnet 324 .

[0056] The N pole of the first magnet 323 is arranged opposite to or adjacent to the N pole of the third magnet 325. The S pole of the first magnet 323 is arranged opposite to or adjacent to the S pole of the fourth magnet 326. The N pole of the second magnet 324 is arranged opposite to or adjacent to the N pole of the fourth magnet 326. The S pole of the second magnet 324 is arranged opposite to or adjacent to the S pole of the third magnet 325.

[0057] During operation, under normal conditions, there are mutual repulsion forces between the N pole of the first magnet 323 and the N pole of the third magnet 325, between the S pole of the first magnet 323 and the S pole of the fourth magnet 326, between the N pole of the second magnet 324 and the N pole of the fourth magnet 326, and between the S pole of the second magnet 324 and the S pole of the third magnet 325, and the first magnet 323, the second magnet 324, the third magnet 325 and the fourth magnet 326 are arranged in a uniform array, and the forces exerted on the connecting shaft 321 are mutually balanced and stable. Under the action of the mutual repulsion forces, the connecting shaft 321 drives the side brush device 310 to maintain a certain balanced tilted state. When the sweeping robot moves forward, the side brush device 310 can collect the corner garbage to the position of the middle sweeping opening 200.

[0058] When the side brush device 310 encounters an obstacle, for example, the obstacle drives the brush 313 device to drive the connecting shaft 321 to move in a certain direction. Figure 4 When rotating clockwise in the direction shown, the external force drives the N pole of the third magnet 325 to overcome the mutual repulsion force and rotate in the direction close to the N pole of the second magnet 324, and the S pole of the fourth magnet 326 to overcome the mutual repulsion force and rotate in the direction close to the S pole of the first magnet 323. As a result, the side brush device 310 can rotate and pass over obstacles. After the side brush device 310 passes over the obstacle, the N pole of the third magnet 325 is repelled by the N pole of the second magnet 324, and the S pole of the fourth magnet 326 is repelled by the S pole of the first magnet 323, so that the connecting shaft 321 drives the side brush device 310 back to the original balanced tilted state.

[0059] It should be noted here that the above embodiment is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention. In other embodiments of the present invention, the N pole of the first magnet 323 is arranged opposite to or adjacent to the N pole of the fourth magnet 326. The S pole of the first magnet 323 is arranged opposite to or adjacent to the S pole of the third magnet 325. The N pole of the second magnet 324 is arranged opposite to or adjacent to the N pole of the third magnet 325. The S pole of the second magnet 324 is arranged opposite to or adjacent to the S pole of the fourth magnet 326.

[0060] In one embodiment of the present invention, the angle between the side brush device 310 and the forward direction of the cleaning robot is an acute angle. Figure 1 As shown, in this embodiment, the forward direction of the sweeping robot is the vertically upward direction as shown in the figure, and the angle between the side brush device 310 and the vertically upward direction is an acute angle, thereby improving the effect of the side brush device 310 collecting garbage toward the middle sweeping opening 200.

[0061] In one embodiment of the present invention, the side brush device 310 includes a base 311 and a scraper bar 312. The base 311 is connected to the connecting shaft 321. The scraper bar 312 is connected to the base 311. The scraper bar 312 extends obliquely from the outer side of the chassis body 100 to the position of the middle sweep opening 200.

[0062] Further, in one embodiment of the present invention, the side brush device 310 further includes a brush 313. The brush 313 is connected to the base 311, and the brush 313 is located on a side of the scraper bar 312 away from the garbage to be cleaned area.

[0063] For example, Figure 1 , Figure 2 and Figure 5 As shown, the side brush device 310 includes a base 311, a scraper bar 312 and a brush 313. The base 311 is connected to the connecting shaft 321, and the base 311 extends obliquely from the outer side of the chassis body 100 to the position of the middle sweep opening 200. A scraper bar 312 is arranged on the base 311 along the extension direction of the base 311. The scraper bar 312 includes but is not limited to a rubber scraper bar 312. A brush 313 is arranged on one side of the scraper bar 312 away from the garbage to be cleaned area. The length of the scraper bar 312 is equal to the length of the brush 313, and the lengths of the scraper bar 312 and the brush 313 are slightly less than the length of the base 311. More specifically, the outer end of the base 311 extends to the outer side of the outer end of the scraper bar 312 and the brush 313, and the inner end of the base 311 is flush with the inner end of the scraper bar 312 and the brush 313.

[0064] During operation, as the sweeping robot moves forward, the garbage in the area to be cleaned is moved by the scraping action of the scraping bar 312 and collected at the position of the middle sweeping opening 200, so as to be sucked into the housing 500 of the sweeping robot through the middle sweeping opening 200. The debris and garbage that are not scraped clean by the scraping bar 312 are further cleaned by the brush 313. At the same time, when the side brush device 310 encounters an obstacle, the obstacle can directly press against the rigid base 311, so that the side brush device 310 overcomes the magnetic repulsive force and rotates to avoid the obstacle. When the side brush device 310 passes over the obstacle, the magnetic repulsive force drives the side brush device 310 to rotate back to a balanced tilted state to normally collect the garbage from the corners.

[0065] The embodiment of the second aspect of the present invention further provides a sweeping robot, comprising a cleaning chassis assembly and a shell 500 .

[0066] The cleaning chassis assembly is mounted to the bottom of the housing 500. A garbage suction device is provided inside the housing 500 at a position corresponding to the middle sweeping opening 200.

[0067] like Figure 1 As shown, the bottom of the housing 500 is connected to the chassis body 100. The middle sweep opening 200 is arranged at the middle position of the chassis body 100. Two running wheels 400 are arranged on both sides of the middle sweep opening 200. A garbage suction device and a garbage storage box are arranged inside the housing 500. The inlet of the garbage suction device is arranged corresponding to the middle sweep opening 200, and the outlet of the garbage suction device is arranged corresponding to the garbage storage box, so as to suck the garbage at the middle sweep opening 200 into the garbage storage box.

[0068] Furthermore, in the sweeping robot provided by the present invention, since it includes the cleaning chassis assembly as described above, it also has the advantages as described above.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
