Description

Cleaning robots and cleaning robot systems Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning robot and a cleaning robot system. Background Art

[0002] The cleaning robot is equipped with a roller brush mechanism at the bottom. The roller brush mechanism sweeps up dust and debris from the ground as the cleaning robot moves. The dust box assembly inside the cleaning robot sucks the dust and debris swept up by the roller brush mechanism into the dust box assembly. In some cleaning scenarios, if there are filaments such as hair on the ground, the filaments can easily be entangled in the roller brush assembly, causing the roller brush assembly to jam and prevent the cleaning robot from operating normally.

[0003] Summary of the Invention

[0004] In view of this, the present application proposes a cleaning robot and a cleaning robot system.

[0005] The cleaning robot proposed in the first aspect of the present application comprises:

[0006] A host assembly having an opening at the bottom;

[0007] A dust box assembly is provided inside the main unit assembly and is used to suck dust and debris;

[0008] The roller brush mechanism includes a housing assembly, a drive assembly, and a roller brush assembly, wherein the housing assembly is arranged at the opening, the housing assembly has an inner cavity and a dust inlet and a dust outlet connected to the inner cavity, the dust inlet is open toward the bottom of the host assembly, the dust outlet is connected to the dust box assembly, the roller brush assembly is arranged in the inner cavity of the housing assembly, the roller brush assembly includes a connecting end and a free end, the connecting end is connected to the drive assembly, and the free end is in a cantilever state;

[0009] Wherein, the dust outlet is located on the housing component close to the free end.

[0010] The cleaning robot system proposed in the second aspect of the present application includes a maintenance station and a cleaning robot, wherein the cleaning robot includes:

[0011] A host assembly having an opening at the bottom;

[0012] A dust box assembly is provided inside the main unit assembly and is used to suck dust and debris;

[0013] The roller brush mechanism includes a housing assembly, a drive assembly, and a roller brush assembly, wherein the housing assembly is arranged at the opening, the housing assembly has an inner cavity and a dust inlet and a dust outlet connected to the inner cavity, the dust inlet is open toward the bottom of the host assembly, the dust outlet is connected to the dust box assembly, the roller brush assembly is arranged in the inner cavity of the housing assembly, the roller brush assembly includes a connecting end and a free end, the connecting end is connected to the drive assembly, and the free end is in a cantilever state;

[0014] Wherein, the dust outlet is located on the housing component close to the free end.

[0015] It can be seen from the above technical solution that the cleaning robot proposed in the first aspect of this application sets the free end of the roller brush to a cantilever state, and the dust outlet of the shell assembly is located at the free end of the shell assembly close to the roller brush. In this way, when a filament is entangled in the roller brush, the suction force formed by the dust box assembly at the dust outlet will suck the filament toward the free end of the roller brush, and finally suck the filament into the dust box assembly, thereby preventing the filament from moving to the connecting end of the roller brush and causing the roller brush to get stuck.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] As shown in Figures 1 to 3, an embodiment of the present application provides a cleaning robot 100. The proposed cleaning robot 100 includes a main unit assembly 10, a dust box assembly 20, and a roller brush mechanism 30. The main unit assembly 10 has an opening 11 at the bottom. The dust box assembly 20 is located within the main unit assembly 10 and is used to suck dust and debris. The roller brush mechanism 30 includes a housing assembly 31, a drive assembly 32, and a roller brush assembly 33. The housing assembly 31 is located at the opening 11 and has an inner cavity and a dust inlet C1 and a dust outlet C2 communicating with the inner cavity. The dust inlet C1 opens toward the bottom of the main unit assembly 10, and the dust outlet C2 communicates with the dust box assembly 20. The roller brush assembly 33 is located within the inner cavity of the housing assembly 31 and includes a connecting end 33a and a free end 33b. The connecting end 33a is connected to the drive assembly 32, and the free end 33b is cantilevered. The dust outlet C2 is located near the free end 33b of the housing assembly 31. The dust outlet C2 is located near the free end 33b of the housing assembly 31. The dust outlet C2 may be opposite to the free end 33b, or opposite to any position between the midpoint between the connecting end 33a and the free end 33b and the free end 33b.

[0038] During use, the dust box assembly 20 operates to generate suction at the dust inlet C1, and the roller brush mechanism 30 operates to sweep up dust and debris on the ground, which then enters the dust box assembly 20 through the dust inlet C1. When there is filamentary material on the ground, the filamentary material is rolled up by the roller brush and, under the action of the suction force generated by the dust box assembly 20, moves to the free end 33b of the roller brush assembly 33, and finally enters the dust box assembly 20 through the dust outlet C2.

[0039] The cleaning robot 100 proposed in the embodiment of the present application sets the free end 33b of the roller brush in a cantilever state, and the dust outlet C2 of the shell assembly 31 is located at the shell assembly 31 near the free end 33b of the roller brush. In this way, when a filament is entangled in the roller brush, the suction force formed by the dust box assembly 20 at the dust outlet C2 will suck the filament toward the free end 33b of the roller brush, and finally suck the filament into the dust box assembly 20, thereby preventing the filament from moving to the connecting end 33a of the roller brush and causing the roller brush to get stuck.

[0040] As shown in FIG4 , in some embodiments, there are two drive assemblies 32, namely a first drive assembly 321 and a second drive assembly 322. The first drive assembly 321 is disposed on one side of the housing assembly 31, and the second drive assembly 322 is disposed on the other side of the housing assembly 31. There are two roller brush assemblies 33, namely a first roller brush assembly 331 and a second roller brush assembly 332. The first roller brush assembly 331 is connected to the first drive assembly 321, and the second roller brush assembly 332 is connected to the second drive assembly 322. The free end 33b of the first roller brush assembly 331 and the free end 33b of the second roller brush assembly 332 are disposed opposite each other.

[0041] As shown in Figures 5 to 7, in some embodiments, the roller brush assembly 33 is provided with a receiving space D near the connecting end 33a. The receiving space D is used to receive filaments that move to the connecting end 33a. This embodiment can prevent a small amount of filaments from moving to the connecting end 33a of the roller brush and becoming entangled in the rotating shaft of the roller brush assembly 33, thereby preventing the drive assembly 32 from rotating and causing damage.

[0042] As shown in Figures 5 to 7, in some embodiments, the roller brush assembly 33 includes a roller brush 333, a shaft assembly 334, and a filament collector 335. One end of the shaft assembly 334 is connected to the drive assembly 32, and the other end of the shaft assembly 334 is disposed within the roller brush 333. The shaft assembly 334 is spaced apart from the inner sidewall of the roller brush 333. The filament collector 335 is disposed around the shaft assembly 334, and the filament collector 335 partially abuts the inner sidewall of the roller brush 333. The roller brush 333, the shaft assembly 334, and the filament collector 335 enclose a receiving space D.

[0043] As shown in Figures 5 to 7, in some embodiments, the filament collector 335 includes a sleeve 336 and a stopper 337. The sleeve 336 is disposed around the outer wall of the shaft assembly 334, and the stopper 337 is disposed around the outer wall of the sleeve 336 and abuts the inner wall of the roller brush 333. The sleeve 336, the stopper 337, and the roller brush 333 enclose a receiving space D.

[0044] As shown in Figure 7, in some embodiments, the blocking member 337 includes a connecting portion 3371 and a blocking portion 3372. The connecting portion 3371 is arranged on the outer wall of the sleeve 336, and the blocking portion 3372 is arranged on the connecting portion 3371 and extends in an arc shape toward the connecting end 33a. The blocking portion 3372 abuts the inner wall of the roller brush 333.

[0045] As shown in FIG. 7 , in some embodiments, an outer wall of the shaft sleeve 336 is provided with an embedding groove 3361 extending circumferentially along the shaft sleeve 336 , and the connecting portion 3371 is embedded in the embedding groove 3361 .

[0046] As shown in Figures 6 and 7, in some embodiments, the shaft assembly 334 includes a transmission shaft 3341, a bearing 3342 and a bearing seat 3343. The bearing seat 3343 is installed on the housing assembly 31, the bearing 3342 is sleeved on the transmission shaft 3341 and installed on the bearing seat 3343, one end of the transmission shaft 3341 is passed through the roller brush 333 and is relatively fixed to the roller brush 333, that is, the transmission shaft 3341 and the roller brush 333 cannot rotate relative to each other, the other end of the transmission shaft 3341 is connected to the driving assembly 32, and the filament collecting member 335 is ringed on the bearing seat 3343.

[0047] In some embodiments, the blocking member 337 is made of a flexible material. This embodiment prevents the blocking portion 3372 and the roller brush 333 from getting stuck, preventing the roller brush 333 from rotating and potentially burning out the drive assembly 32. Understandably, in some usage scenarios, there may be large debris on the ground, such as melon seed shells, which could get stuck between the blocking portion 3372 and the roller brush 333. If the blocking portion 3372 is made of a hard material, this could prevent the roller brush 333 from rotating, and thus prevent the drive shaft 3341 from rotating, risking burning out the drive assembly 32.

[0048] As shown in FIG7 , in some embodiments, the bearing seat 3343 includes a seat body 3344 and an annular shielding portion 3345. The annular shielding portion 3345 is disposed around the outer wall of the seat body 3344 and is spaced apart from the end of the roller brush 333. The filament enters the receiving space D through the gap between the annular shielding portion 3345 and the end of the roller brush 333. In this embodiment, the annular shielding portion 3345 can block the filament from moving toward the drive assembly 32, preventing the filament from being entangled in the drive assembly 32 and causing the drive assembly 32 to become stuck.

[0049] As shown in Figure 8, in some embodiments, a foolproof structure is provided between the first roller brush assembly 331 and the housing assembly 31. With this embodiment, incorrect installation of the first roller brush assembly 331 and the second roller brush assembly 332 can be avoided.

[0050] Exemplarily, the outer side wall of the bearing seat 3343 of the first roller brush assembly 331 is at least partially in an arc shape E1, and the portion where the outer shell assembly 31 cooperates with the bearing seat 3343 is at least partially in an arc shape E1, and the two cooperate to form the fool-proof structure.

[0051] As shown in Figure 9, in some embodiments, a foolproof structure is provided between the second roller brush assembly 332 and the housing assembly 31. With this embodiment, incorrect installation of the first roller brush assembly 331 and the second roller brush assembly 332 can be avoided.

[0052] Exemplarily, the outer side wall of the bearing seat 3343 of the second roller brush assembly 332 is at least partially polygonal in shape E2, and the portion where the outer shell assembly 31 cooperates with the bearing seat 3343 is at least partially polygonal in shape E2, and the two cooperate to form the fool-proof structure.

[0053] As shown in Figures 10 and 11, in some embodiments, the first roller brush assembly 331 includes a first roller brush 3311 and a first shaft assembly 3312 connected to the first roller brush 3311. A foolproof structure is provided between the first roller brush 3311 and the first shaft assembly 3312. This prevents assembly errors between the first roller brush 3311, the first shaft assembly 3312, the second roller brush 3321, and the second shaft assembly 3322.

[0054] Illustratively, the outer side wall of the first shaft assembly 3312 is provided with three axially extending first ribs 3313, and the first roller brush 3311 is provided with three axially extending first long grooves 3314. The first ribs 3313 and the first long grooves 3314 cooperate to form the fool-proof structure.

[0055] As shown in Figures 12 and 13, in some embodiments, the second roller brush assembly 332 includes a second roller brush 3321 and a second shaft assembly 3322 connected to the second roller brush 3321. A foolproof structure is provided between the second roller brush 3321 and the second shaft assembly 3322. This embodiment can prevent assembly errors between the first roller brush 3311, the first shaft assembly 3312, the second roller brush 3321, and the second shaft assembly 3322.

[0056] Illustratively, the outer side wall of the second shaft assembly 3322 is provided with two axially extending second ribs 3323, and the second roller brush 3321 is provided with two axially extending second long grooves 3324, and the second ribs 3323 and the second long grooves 3324 cooperate to form the fool-proof structure.

[0057] As shown in Figures 14 and 15, in some embodiments, the cleaning robot 100 further includes a suspension assembly 40, which connects the main assembly 10 and the roller brush mechanism 30, allowing the roller brush mechanism 30 to float up and down relative to the main assembly 10. In this embodiment, by providing the suspension assembly 40, the roller brush mechanism 30 can move up and down, so that the cleaning robot 100 has a better obstacle-crossing function.

[0058] In some embodiments, the suspension assembly 40 includes a first connector 41, a second connector 42, and a connecting rod assembly 43. The first connector 41 is connected to the main assembly 10, and the second connector 42 is connected to the roller brush assembly 33. One end of the connecting rod assembly 43 is rotatably connected to the first connector 41, and the other end of the connecting rod assembly 43 is rotatably connected to the roller brush assembly 33.

[0059] In some embodiments, the connecting rod assembly 43 includes a first connecting rod 431 and a second connecting rod 432. One end of the first connecting rod 431 is rotatably connected to the first connecting member 41, and the other end of the first connecting rod 431 is rotatably connected to the roller brush assembly 33. One end of the second connecting rod 432 is rotatably connected to the first connecting member 41, and the other end of the second connecting rod 432 is rotatably connected to the roller brush assembly 33. The first connecting rod 431 and the second connecting rod 432 are arranged in parallel.

[0060] It should be noted that the connecting rod assembly 43 is not limited to being configured to include the first connecting rod 431 and the second connecting rod 432. In some other embodiments, the connecting rod assembly 43 can also be configured to include only the first connecting rod 431, as long as the suspension assembly 40 enables the roller brush mechanism 30 to float up and down.

[0061] As shown in Figure 4, in some embodiments, the housing assembly 31 includes an upper housing assembly 311, a lower housing assembly 312, and a support member 313. The upper housing assembly 311 is provided with a dust outlet C2, and the lower housing assembly 312 is provided with a dust inlet C1. The upper housing assembly 311 and the lower housing assembly 312 enclose an inner cavity. The support member 313 is disposed between the upper housing assembly 311 and the lower housing assembly 312. The support member 313 cooperates with the upper housing assembly 311 to lock the connecting end 33a of the roller brush assembly 33. During assembly, the support member 313 is first connected to the upper housing assembly 311 to clamp the connecting end 33a of the roller brush assembly 33, and then the lower housing assembly 312 is assembled and fixed to the upper housing assembly 311.

[0062] In some embodiments, one end of the support member 313 is rotatably connected to the upper housing assembly 311, while the other end of the support member 313 is snap-fitted to the upper housing assembly 311. During assembly, the connecting end 33a of the roller brush assembly 33 is positioned between the upper housing assembly 311 and the support member 313. The support member 313 is then rotated until it snaps into place with the upper housing assembly 311, securing the connecting end 33a of the roller brush assembly 33. This embodiment greatly facilitates installation of the roller brush assembly 33.

[0063] As shown in Figures 4 and 9, in some embodiments, the support member 313 is provided with a first limiting portion 3131, and the connecting end 33a is provided with a second limiting portion 33a1. The first limiting portion 3131 and the second limiting portion 33a1 cooperate to limit the movement of the roller brush assembly 33 relative to the support member 313. In this embodiment, the limiting action of the first limiting portion 3131 and the second limiting portion 33a1 can prevent the roller brush assembly 33 from shaking after being installed in the housing assembly 31, allowing the roller brush assembly 33 to operate stably.

[0064] Illustratively, the first limiting portion 3131 includes a protrusion provided on the support member 313, and the second limiting portion 33a1 is a through-hole provided on the connecting end 33a, in which the protrusion is embedded to limit the movement of the roller brush assembly 33 relative to the support member 313. Of course, the first limiting portion 3131 and the second limiting portion 33a1 are not limited to the matching mode of the protrusion and the through-hole, and can also be the matching mode of the protrusion and the slot, and the specific configuration can be determined according to actual design requirements.

[0065] As shown in Figure 4, in some embodiments, the lower shell assembly 312 includes a lower shell 3121 and a protective shell 3122. The lower shell 3121 is connected to the upper shell assembly 311, and the protective shell 3122 is detachably connected to the lower shell 3121. Optionally, the lower shell 3121 and the upper shell assembly 311 are fixed with bolts.

[0066] As shown in FIG4 , the lower housing assembly 312 further includes a hook member 3123 and an elastic member 3124. The lower housing 3121 includes a first side F1 and a second side F2 opposite the first side F1. The first side F1 faces the upper housing assembly 311. The lower housing 3121 is provided with an assembly hole 3125 extending from the first side F1 to the second side F2. The hook member 3123 is movably mounted on the lower housing 3121. The hook member 3123 partially penetrates the assembly hole 3125 and hooks onto the first side F1 of the lower housing 3121. The elastic member 3124 is used to provide elastic force to keep the hook member 3123 hooked to the first side F1 of the lower housing 3121. To remove the protective shell 3122, the hook member 3123 is moved to move the latch into the assembly hole 3125, and then the protective shell 3122 is removed.

[0067] As shown in Figures 1 and 4, in some embodiments, the dust inlet C1 includes a front side G1 and a rear side G2 opposite the front side G1, and the direction from the rear side G2 toward the front side G1 is the forward direction of the cleaning robot 100. The roller brush mechanism 30 also includes a scraper bar 34, which is mounted on the lower housing assembly 312 and located at the rear side G2 of the dust inlet C1. The scraper bar 34 is used to abut the ground to prevent dust and debris from escaping from the rear of the cleaning robot 100. In this embodiment, the scraper bar 34 prevents dust and debris from escaping from the rear of the cleaning robot 100, allowing the cleaning robot 100 to achieve a better cleaning effect.

[0068] In some embodiments, the scraper bar 34 is sandwiched between the lower shell 3121 and the protective shell 3122 , which facilitates the disassembly, assembly and replacement of the scraper bar 34 .

[0069] As shown in Figures 1 and 4, in some embodiments, the main body assembly 10 includes a chassis 12 having an opening 11, and the housing assembly 31 has an overlapping portion 314. The overlapping portion 314 overlaps the chassis 12 to define the height of the roller brush assembly 33 relative to the ground. In this embodiment, the height of the roller brush assembly 33 relative to the ground can be effectively controlled, so that the roller brush assembly 33 can achieve a good cleaning effect while avoiding the situation where the roller brush assembly 33 contacts the ground extensively, thereby preventing the cleaning robot 100 from experiencing a large amount of resistance.

[0070] In some embodiments, the outer shell component 31 is made of a flexible material at least around the dust outlet C2. In this embodiment, the outer shell component 31 and the dust box component 20 are softly connected, so that the roller brush mechanism 30 has space to float up and down.

[0071] It should be noted that the roller brush mechanism 30 of the proposed cleaning robot 100 is not limited to the aforementioned method of including two drive assemblies 32 and two roller brush assemblies 33. For example, in some other embodiments, as shown in Figures 16 and 17, the roller brush mechanism 30 includes only one drive assembly 32 and one roller brush assembly 33. Similarly, in this embodiment, the connecting end 33a of the roller brush assembly 33 is connected to the drive assembly 32, the free end 33b of the roller brush assembly 33 is in a cantilevered state, and the dust outlet C2 is located near the free end 33b of the housing assembly 31. Similarly, when a filament is entangled in the roller brush 333, the suction force generated by the dust box assembly 20 at the dust outlet C2 will attract the filament to move toward the free end 33b of the roller brush 333, and ultimately suck the filament into the dust box assembly 20, thereby preventing the filament from moving to the connecting end 33a of the roller brush 333 and causing the roller brush 333 to become stuck.

[0072] In some embodiments, the roller brush assembly 33 includes a roller brush 333, which includes a body 3331 and a plurality of brush strips 3332. The plurality of brush strips 3332 are disposed on the outer sidewall of the body 3331 and extend in the longitudinal direction of the body 3331. The brush strips 3332 are provided with steps 3333, which are used to prevent filaments on the roller brush 333 from moving from the free end 33b toward the connecting end 33a. In this embodiment, the provision of the steps 3333 further prevents filaments entangled in the roller brush 333 from moving toward the connecting end 33a, thereby reducing the risk of the roller brush mechanism 30 becoming stuck.

[0073] It should be noted that the brush strip 3332 extending in the length direction of the main body 3331 does not necessarily extend in a straight line along the axial direction of the main body 3331 , but may also extend in a spiral shape along the main body 3331 .

[0074] In some embodiments, the outer diameter of the roller brush 333 gradually decreases from the connecting end 33a toward the free end 33b. In this embodiment, since the outer diameter of the roller brush 333 gradually decreases, the filament will become loose during the movement toward the free end 33b, facilitating the movement of the filament toward the free end 33b.

[0075] In some embodiments, the roller brush 333 has a rotation axis L, and the angle between the sidewall of the roller brush 333 and the rotation axis L is 0°-10°.

[0076] In some embodiments, the roller brush assembly 33 includes a roller brush 333, and the drive assembly 32 includes a motor 323 and a gearbox 324. The motor 323 is mounted on the main assembly 10, and the gearbox 324 is connected to the motor 323. The shaft extending from the gearbox 324 is connected to the roller brush 333. In this embodiment, the roller brush 333 has a larger portion connected to the shaft extending from the gearbox 324, which can improve the rigidity of the roller brush 333.

[0077] In some embodiments, the motor 323 is rotatably connected to the main assembly 10, so that the roller brush mechanism 30 can be rotated out of the opening 11 as a whole. In this embodiment, the roller brush 333 can be easily assembled and disassembled.

[0078] In some embodiments, the roller brush assembly 33 includes a roller brush 333 and a shaft assembly 334, the drive assembly 32 includes a motor 323, a gearbox 324 and a coupling 325, the motor 323 is installed on the main assembly 10, the gearbox 324 is connected to the motor 323, one end of the shaft assembly 334 is connected to the roller brush 333, and the other end of the shaft assembly 334 is connected to the gearbox 324 through the coupling 325.
