[0048] Referring to Figure 1 In an embodiment of the present application, a sweeping robot 200 is provided, which includes a dust collection system, a walking system and a power supply system. The dust collection system is used to collect dust on the ground, the walking system is used to drive the sweeping robot 200 to move, and the power supply system is used to provide energy for the dust collection system and the walking system to work.

[0049] The dust collection system includes a rolling brush mechanism 100, a dust collection box, an air duct and a fan. The dust collection box is connected to the outlet of the rolling brush mechanism 100, and the air duct is connected between the dust collection box and the fan. When the rolling brush mechanism 100 works, it brings up the dust on the ground, and then the air mixed with dust is sucked into the inside of the sweeping robot 200 by the suction force generated by the fan. When the airflow mixed with dust passes through the dust collection box, the dust is filtered in the dust collection box, and the clean air is discharged from the fan after passing through the air duct. In this way, the dust collection function is realized.

[0050] Referring to Figures 1-2The rolling brush mechanism 100 comprises a housing 10, a rolling brush assembly 20 and a rolling brush cover assembly 30. The rolling brush cover assembly 30 is movably arranged on the housing 10, and a rolling brush cavity 50 is formed between the rolling brush cover assembly 30 and the housing 10. The rolling brush assembly 20 is arranged in the rolling brush cavity 50, so as to be installed and protected by the rolling brush cavity 50.

[0051] Referring to Figures 4-9 Specifically, the rolling brush cover assembly 30 comprises a rolling brush cover 32, a pressing cover 34 and a scraping strip 36. The rolling brush cover 40 is movably arranged on the housing 10, and a rolling brush cavity 50 is formed between the rolling brush cover 40 and the housing 10. The rolling brush assembly 20 is arranged in the rolling brush cavity 50. In addition, the rolling brush cover 32 is provided with a dust suction port 33 which is in communication with the rolling brush cavity 40. The rolling brush assembly 20 in the rolling brush cavity 40 can clean the ground through the dust suction port 33. The pressing cover 34 is arranged on the side of the rolling brush cover 32 which is away from the housing 10. The root of the scraping strip 36 is pressed between the pressing cover 34 and the rolling brush cover 32, so as to be pressed and fixed on the rolling brush cover 32 by the pressing cover 34. The scraping strip 36 is used to gather the garbage on the ground to the dust suction port 33, so as to facilitate cleaning.

[0052] In some embodiments, the rolling brush cover assembly 30 is configured to extend along a first direction. The rolling brush mechanism 100 further comprises a buckle assembly 50. The buckle assembly 50 comprises a buckle 52 which is movably arranged relative to the rolling brush cover assembly 30 along the first direction. The buckle 52 can be buckled and separated from the housing 10. When the buckle 52 is buckled with the housing 10, the rolling brush cover assembly 30 is closed, and the rolling brush cover assembly 30 is arranged on the outside of the rolling brush assembly 20 in the housing 10, so as to protect the rolling brush assembly 20. When the buckle 52 is separated from the housing 10, the rolling brush cover assembly 30 is opened, and the user can disassemble, clean and replace the rolling brush assembly 20 in the housing 10.

[0053] The buckle assembly 50 further comprises an elastic member 54 which is abutted between the buckle 52 and the rolling brush cover assembly 30. The elastic member 54 provides the buckle 52 with an elastic force which drives the buckle 52 to move in the direction of buckling with the housing 10. That is, the elastic member 54 is abutted between the rolling brush cover assembly 30 and the buckle 52. The buckle 52 can slide to be buckled with the housing 10 under the action of the elastic member 54, so as to buckle and fix the rolling brush cover assembly 30 on the housing 10. When it is needed to open the rolling brush cover assembly 30, an external force is only needed to be applied on the buckle 52, so that the buckle 52 can move in the direction of unlocking with the housing 10 by overcoming the elastic force.

[0054] In some embodiments, the rolling brush mechanism 100 comprises at least two sets of buckle assemblies 50, which are arranged along the first direction and spaced apart from each other on the rolling brush cover assembly 30. Each buckle 52 is in abutment with an elastic member 54 between the rolling brush cover assembly 30. Specifically, each buckle 52 has two opposite assembly ends 53 along the first direction. In the two adjacent sets of buckle assemblies 50, the assembly end 53 of one of the two buckles 52 towards the side of the other buckle is in abutment with the elastic member 54 between the rolling brush cover assembly 30. That is, the elastic member 54 is arranged between the assembly ends 53 of the two adjacent buckles 52 facing each other and the rolling brush cover assembly 30. The two adjacent buckles 52 can move away from each other under the action of the respective abutting elastic member 54 to be buckled with the shell 10. When it is necessary to open the rolling brush cover assembly 30, the operator only needs to place the thumb and index finger on the two adjacent buckles 52 and pinch the two buckles 52 towards each other. The two buckles 52 can be separated from the shell 10 to open the rolling brush cover assembly 30.

[0055] In addition, each buckle 52 has two assembly ends 53, for example Figure 5 In the embodiment, the elastic member 54 can be assembled on the assembly end 53 of the right end of the left buckle 52, and the elastic member 54 can also be assembled on the assembly end 53 of the left end of the right buckle 52. In this way, the assembly ends 53 are arranged on both sides of the buckle 52, so that the same buckle 52 can be assembled on any one side of the two opposite sides of the elastic member 54 along the first direction. The plurality of buckles 52 can be interchangeable and universal, and there is no need to produce a plurality of buckles 52 with different structures, thereby saving production costs.

[0056] Specifically, in the embodiment, the rolling brush mechanism 100 comprises two sets of buckle assemblies 50. The two buckles 52 in the two sets of buckle assemblies 50 move towards or away from each other. For example, when the two buckles 52 move away from each other under the action of the respective abutting elastic member 54, the two buckles 52 are buckled with different positions of the shell 10. When the two buckles 52 move towards each other under the pinching of the operator, the two buckles 52 are separated from the shell 10 to allow the rolling brush cover assembly 30 to be opened.

[0057] In some embodiments, the buckle 52 comprises a body 521 and a buckling part 523. The body 521 is movably arranged on the rolling brush cover assembly 30. The buckling part 523 is arranged on the side of the body 521 towards the shell 10 and protrudes from the rolling brush cover 32. In the direction in which the shell 10 points to the rolling brush cover 32, the buckling part 523 is buckled with the shell 10. In this way, the buckling part 523 is arranged on the buckle 52 and buckled with the shell 10 in the direction in which the shell 10 points to the rolling brush cover 32. After the buckling part 523 is buckled with the shell 10, the buckling part 523 will not be separated from the shell 10 in the direction in which the shell 10 points to the rolling brush cover 32, so as to fix the rolling brush cover 32 on the shell 10.

[0058] Further, the buckle 52 further comprises two lugs 525, the body 521 is provided with the two lugs 525 at opposite ends in the first direction, and the two lugs 525 are movably arranged in the roller brush cover assembly 30 in the first direction to guide the body 521 to move in the first direction through the two lugs 525.

[0059] Specifically, the roller brush cover assembly 30 is internally formed with a receiving cavity 35, the body 521 and the two lugs 525 are movably arranged in the receiving cavity 35 in the first direction, the buckle portion 523 extends out of the receiving cavity 35 in a second direction intersecting the first direction, and a gap 524 is reserved between the buckle portion 523 and the roller brush cover assembly 30. In this way, the body 521 and the two lugs 525 are installed through the receiving cavity 35 in the roller brush cover assembly 30, and the body 521 and the two lugs 525 are allowed to reciprocate in the first direction through the receiving cavity 35. At the same time, the buckle portion 523 extends out of the receiving cavity 35, and when the buckle portion 523 is moved to be buckled with the shell 10, at least part of the shell 10 is positioned in the gap 524 between the buckle portion 523 and the roller brush cover assembly 30 to achieve buckling of the roller brush cover assembly 30 with the shell 10.

[0060] Optionally, the pressure cover 34 in the roller brush cover assembly 30 is arranged on the side of the roller brush cover 32 away from the shell 10, and the pressure cover 34 and the roller brush cover 32 surround to form the receiving cavity 35 to clamp the lugs 525 between the pressure cover 34 and the roller brush cover 32 to limit the lugs 525. Specifically, the roller brush cover 32 comprises a cover body 321 and a guide rail 323, the pressure cover 34 is arranged on the cover body 321, the pressure cover 34 and the cover body 321 surround to form the receiving cavity 35, the guide rail 323 is arranged on the side of the cover body 321 facing the pressure cover 34 and located in the receiving cavity 35, and the lugs 525 are movably arranged between the guide rail 323 and the pressure cover 34 in the first direction. In this way, the guide rail 323 is arranged on the roller brush cover 32 to allow the lugs 525 to be movably arranged along the guide rail 323 to support the lugs 525 through the guide rail 323, and the pressure cover 34 is used to press the lugs 525 to prevent the lugs 525 from falling off the roller brush cover 32.

[0061] Specifically, the guide rail 323 comprises a first sub-guide rail 324 and a second sub-guide rail 325, the first sub-guide rail 324 and the second sub-guide rail 325 are oppositely spaced in a third direction perpendicular to the first direction and the second direction, an active slot 326 is formed between the first sub-guide rail 324 and the second sub-guide rail 325, and the elastic member 54 is located in the active slot 326 and abuts between the buckle 52 and the cover body 321. In this way, the lugs 525 are guided to slide through the guide rail 323, and the active slot 326 formed by the guide rail 323 accommodates the elastic member 54 between the lugs 525 and the guide rail 323 to improve the space utilization.

[0062] Specifically, the cover 321 is provided with a baffle 327 connected between the first sub-guide rail 324 and the second sub-guide rail 325, one end of the elastic member 54 abuts against the baffle 327, and the other end abuts against the buckle 52, so that the elastic member 54 is assembled.

[0063] Further, the buckle 52 further comprises two mounting portions 527, the body 521 is further provided with the two mounting portions 527 at opposite ends in the first direction, respectively, the mounting portions 527 are connected with the lugs 525 and / or the body 521, the mounting portions 527 are configured as the assembly end 53, the elastic member 54 abuts against the mounting portions 527 and the roller brush cover assembly 30, so that the mounting portions 527 cooperate with one end of the elastic member 54, facilitating assembly of the elastic member 54. It can be understood that the cover elastic member 54 is a spring. Moreover, the body 521 has a middle line perpendicular to the first direction, and the two mounting portions 527 are symmetrically arranged relative to the middle line. In this way, the two mounting portions 527 on both sides of the body 521 are symmetric to each other and have the same structure, and the elastic member 54 can be assembled to any one of the two mounting portions 527, so as to ensure that the buckle 52 can be universal.

[0064] Optionally, the buckle 52 further comprises a knob platform 528, the knob platform 528 is arranged at one end of the body 521 away from the buckling portion 523, the cover 34 is provided with a through hole 341 communicating with the accommodating cavity 35, and the knob is movably arranged in the through hole 341 along the first direction. In this way, the knob platform 528 can be exposed outside the cover 34 through the through hole 341, the operator can contact the knob platform 528, and apply an operating force to the knob platform 528 to unlock the buckle 52.

[0065] Referring to Figures 10-15 In another embodiment of the present application, a roller brush mechanism 100 is further provided, which is mainly different from the above-mentioned embodiments in that the elastic member 54 is an elastic arm 55, and the buckle 52 is not provided with the mounting portion 527, and the elastic arm 55 abuts against the body 521 of the buckle 52 and the roller brush cover 32, and other structures and connection relationships are consistent with the above-mentioned embodiments.

[0066] The roller brush mechanism 100 comprises a shell 10, a roller brush assembly 20 and a roller brush cover assembly 30, the roller brush cover assembly 30 is movably arranged on the shell 10, and a roller brush cavity 40 is formed between the roller brush cover assembly 30 and the shell 10, and the roller brush assembly 20 is arranged in the roller brush cavity 40, so as to install and protect the roller brush assembly 20 through the roller brush cavity 40.

[0067] Specifically, the roller brush cover assembly 30 comprises a roller brush cover 32, a pressing cover 34 and a scraping strip 36. The roller brush cover 32 is movably arranged on the shell 10 to form a roller brush cavity 40 between the roller brush cover 32 and the shell 10, and the roller brush assembly 20 is arranged in the roller brush cavity 40. A dust suction port 33 is formed in the roller brush cover 32 and communicates with the roller brush cavity 40. The roller brush assembly 20 in the roller brush cavity 40 can clean the ground through the dust suction port 33. The pressing cover 34 covers the side of the roller brush cover 32 away from the shell 10.

The buckle assembly 50 comprises a buckle 52 movably arranged relative to the roller brush cover 32 along the first direction. The buckle 52 can be buckled and unbuckled with the shell 10. When the buckle 52 is buckled with the shell 10, the roller brush cover assembly 30 is closed, and the roller brush cover 32 covers the outside of the roller brush assembly 20 in the shell 10 to protect the roller brush assembly 20. When the buckle 52 is unbuckled with the shell 10, the roller brush cover assembly 30 is opened, and the roller brush assembly 20 in the shell 10 can be disassembled, cleaned and replaced.

[0069] The buckle assembly 50 further comprises a resilient member 54 abutting between the buckle 52 and the roller brush cover 32. The resilient member 54 provides the buckle 52 with an elastic force to drive the buckle 52 to move to the direction of buckling with the shell 10. That is, the resilient member 54 abuts between the roller brush cover 32 and the buckle 52. The buckle 52 can slide to buckle with the shell 10 under the action of the resilient member 54, so as to buckle and fix the roller brush cover assembly 30 on the shell 10. When it is needed to open the roller brush cover assembly 30, an external force is only needed to be applied on the buckle 52 to enable the buckle 52 to overcome the elastic force and move to the direction of unbuckling with the shell 10.

[0070] The resilient member 54 is an elastic arm 55, and the elastic arm 55 is arranged on any one of the buckle 52 and the roller brush cover 32. In this way, the elastic arm 55 is directly arranged on the buckle 52 or the roller brush cover 32, and the elastic arm 55 is used to provide the buckle 52 with a reset elastic force. When the roller brush cover 32 and the buckle 52 are assembled together, the elastic arm 55 will abut between the roller brush cover 32 and the buckle 52. The resilient member 54 does not need to be separately assembled when the buckle 52 is assembled, which simplifies the assembly process and improves the assembly efficiency. It can be understood that the resilient member 54 can also be a spring in some other embodiments, which is not limited herein.

[0071] Further, the number of buckles 52 is two, and the assembly end 53 of one of the two adjacent buckles 52 towards the other one abuts against the elastic arm 55 between the roller brush cover 32, so that the elastic arm 55 is arranged on the side of the two buckles 52 facing away from each other, and the two buckles 52 can move away from each other under the action of the respective abutting elastic arm 55.

[0072] Specifically, the elastic arm 55 is arranged on the roller brush cover 32 and is integrally formed with the roller brush cover 32. In this way, the elastic arm 55 is integrally formed with the roller brush cover 32, and the elastic arm 55 is formed at the required position in advance, so that the buckle 52 only needs to be abutted on the elastic arm 55 during assembly, and the assembly is simple. At the same time, each buckle 52 has two opposite assembly ends 53 in the first direction, so that the buckle 52 can be used at each elastic arm 55, improving the universality of the buckle 52 and reducing the production cost. It can be understood that in other embodiments, the elastic arm 55 can also be integrally formed on the buckle 52, but in this way, the left and right buckles 52 cannot be universal, but the assembly can also be simplified.

[0073] Optionally, the elastic arm 55 is configured as an arc-shaped elastic arm 55, which can elastically deform by changing the bending degree of the arc-shaped arm when abutting against external force, and can provide elastic restoring force for the buckle 52. Further optionally, the elastic arm 55 includes a first sub-arm 551 and a second sub-arm 552 arranged in the first direction and connected to each other; one of the first sub-arm 551 and the second sub-arm 552 is arranged to be bent towards the housing 10, and the other of the first sub-arm 551 and the second sub-arm 552 is arranged to be bent away from the housing 10, so that the elastic arm 55 can be bent and deformed in a larger range, and the elasticity of the elastic arm 55 is better.

[0074] Specifically, the buckle 52 includes a body 521 and a clamping portion 523, the body 521 is movably arranged on the roller brush cover 32, the clamping portion 523 is arranged on the side of the body 521 facing the shell 10 and protrudes from the roller brush cover 32, and the clamping portion 523 is limitedly clamped with the shell 10 in the direction in which the shell 10 points to the roller brush cover 32. In this way, the clamping portion 523 is arranged on the buckle 52 and is limitedly clamped with the shell 10 in the direction in which the shell 10 points to the roller brush cover 32, so that the clamping portion 523 cannot be separated from the shell 10 in the direction in which the shell 10 points to the roller brush cover 32 after being clamped with the shell 10, thereby fixing the roller brush cover 32 on the shell 10. In addition, the opposite sides of the body 521 along the first direction are respectively configured as two assembly ends 53, the body 521 can abut against the elastic arm 55, and the opposite sides of the body 521 can both cooperate with the elastic arm 55, thereby improving the versatility of the buckle 52. Specifically, the body 521 has a middle line perpendicular to the first direction, and the body 521 is symmetrically arranged relative to the middle line. In this way, the two mounting portions 527 on the two sides of the body 521 are mutually symmetrical and have the same structure, and the elastic arm 55 can abut against any one of the two mounting portions 527, thereby ensuring that the buckle 52 can be used universally.

[0075] Further, the buckle 52 further includes two lugs 525, the opposite ends of the body 521 along the first direction are respectively provided with the two lugs 525, and the two lugs 525 are movably arranged in the roller brush cover assembly 30 along the first direction, so as to guide the body 521 to move along the first direction through the two lugs 525.

[0076] Optionally, the pressure cover 34 is arranged on the side of the roller brush cover 32 away from the shell 10 in the roller brush cover assembly 30, a containing cavity 35 is formed between the pressure cover 34 and the roller brush cover 32, the body 521 and the two lugs 525 are movably arranged in the containing cavity 35 along the first direction, the clamping portion 523 protrudes from the containing cavity 35, and a gap 524 is reserved between the clamping portion 523 and the roller brush cover assembly 30 along a second direction intersecting the first direction. In this way, the containing cavity 35 in the roller brush cover assembly 30 allows the body 521 and the two lugs 525 to reciprocate along the first direction and clamps the lugs 525 between the pressure cover 34 and the roller brush cover 32, thereby limiting the lugs 525. At the same time, the clamping portion 523 protrudes from the containing cavity 35, and when the clamping portion 523 is clamped with the shell 10, at least part of the shell 10 is limitedly arranged in the gap 524 between the clamping portion 523 and the roller brush cover 32, thereby achieving the clamping of the roller brush cover assembly 30 and the shell 10.

[0077] Specifically, the roller brush cover 32 comprises a cover body 321 and a guide rail 323, the pressing cover 34 is arranged on the cover body 321, a containing cavity 35 is formed between the cover body 321 and the pressing cover 34, the guide rail 323 is arranged on a side of the cover body 321 facing the pressing cover 34 and located in the containing cavity 35, and the lug 525 is movably arranged between the guide rail 323 and the pressing cover 34 along the first direction. In this way, the guide rail 323 is arranged on the roller brush cover 32, allowing the lug 525 to be movably arranged along the guide rail 323, so as to support the lug 525 through the guide rail 323, and prevent the lug 525 from falling off the roller brush cover 32 by pressing the lug 525 with the pressing cover 34.

[0078] Specifically, the guide rail 323 comprises a first sub-guide rail 324 and a second sub-guide rail 325, the first sub-guide rail 324 and the second sub-guide rail 325 are oppositely arranged along a third direction perpendicular to the first direction and the second direction, and a movable slot 326 is formed between the first sub-guide rail 324 and the second sub-guide rail 325. One end of the elastic arm 55 is fixed in the movable slot 326, the other end of the elastic arm 55 abuts against the body 521 of the buckle 52, and the elastic arm 55 is telescopically arranged in the movable slot 326 along the first direction. In this way, the guide rail 323 guides the sliding of the lug 525, and the movable slot 326 formed by the guide rail 323 accommodates the elastic arm 55, so as to improve the space utilization by housing the elastic arm 55 between the lug 525 and the guide rail 323.

[0079] More specifically, the cover body 321 is provided with a baffle 327 connected between the first sub-guide rail 324 and the second sub-guide rail 325, one end of the elastic arm 55 is connected to the baffle 327, and the other end of the elastic arm 55 abuts against the body 521 of the buckle 52. In this way, the elastic arm 55 is assembled.

[0080] Optionally, the buckle 52 further comprises a buckle hand platform 528, the buckle hand platform 528 is arranged at one end of the body 521 away from the buckle part 523, the pressing cover 34 is provided with a through hole 341 communicating with the containing cavity 35, and the buckle hand platform 528 extends into the through hole 341 and is movably arranged in the through hole 341 along the first direction. In this way, the buckle hand platform 528 can be exposed outside the pressing cover 34 through the through hole 341, and an operator can contact the buckle hand platform 528 and apply an operating force to the buckle hand platform 528 to unlock the buckle 52.

[0081] Based on the same inventive concept, the application also provides a rolling brush mechanism 100 in an embodiment. The rolling brush mechanism 100 comprises a housing 10, a rolling brush cover 32 and a buckle assembly 50. The rolling brush cover 32 is movably arranged on the housing 10 and forms a rolling brush cavity 40 with the housing 10. The rolling brush assembly 20 is arranged in the rolling brush cavity 40. The rolling brush cover 32 is configured to extend along a first direction. The buckle assembly 50 comprises a buckle 52 movably arranged relative to the rolling brush cover 32 along the first direction. The buckle 52 can be buckled to and separated from the housing 10. When the buckle 52 is buckled to the housing 10, the rolling brush cover assembly 30 is closed, and the rolling brush cover 32 is arranged outside the rolling brush assembly 20 in the housing 10 to protect the rolling brush assembly 20. When the buckle 52 is separated from the housing 10, the rolling brush cover assembly 30 is opened, and the rolling brush assembly 20 in the housing 10 can be disassembled, cleaned and replaced.

[0082] The buckle assembly 50 further comprises an elastic member 54 arranged between the buckle 52 and the rolling brush cover 32. The elastic member 54 provides an elastic force to the buckle 52 to move the buckle 52 to the direction of buckling to the housing 10. That is, the elastic member 54 is arranged between the rolling brush cover assembly 30 and the buckle 52. The buckle 52 can slide to the direction of buckling to the housing 10 under the action of the elastic member 54, so that the rolling brush cover assembly 30 is buckled and fixed to the housing 10. When it is needed to open the rolling brush cover assembly 30, an external force is applied to the buckle 52 to move the buckle 52 to the direction of separating from the housing 10 against the elastic force.

[0083] In some embodiments, the rolling brush mechanism 100 comprises at least two buckle assemblies 50 arranged in the rolling brush cover assembly 30 along the first direction. The elastic member 54 is arranged between each buckle 52 and the rolling brush cover assembly 30. Specifically, each buckle 52 has two opposite assembly ends 53 along the first direction. In the two adjacent buckle assemblies 50, the elastic member 54 is arranged between the assembly end 53 of one of the two buckles 52 and the rolling brush cover assembly 30. That is, the elastic member 54 is arranged between the assembly ends 53 of the two adjacent buckles 52 and the rolling brush cover assembly 30. The two adjacent buckles 52 can move to the direction of moving away from each other under the action of the respective elastic member 54 to be buckled to the housing 10. When it is needed to open the rolling brush cover assembly 30, the operator only needs to pinch the two adjacent buckles 52 to the direction of moving close to each other with the thumb and the index finger to separate the two buckles 52 from the housing 10 to open the rolling brush cover assembly 30.

[0084] In addition, each buckle 52 has two assembly ends 53, for example Figure 5In the middle, the elastic member 54 can be assembled at the assembling end 53 at the right end of the left buckle 52, and the elastic member 54 can also be assembled at the assembling end 53 at the left end of the right buckle 52. In this way, the assembling end 53 is arranged at both sides of the buckle 52, so that the same buckle 52 can be assembled at any one side of the two opposite sides of the elastic member 54 in the first direction, and a plurality of buckles 52 can be interchangeable, without the need to produce a plurality of buckles 52 with different structures, thereby saving production cost.
