The utility model provides an limit brush mechanism is applied to cleaning machines people, aims at making cleaning machines people clean when treating clean surface in needs, and brush hair 21 of brush hair subassembly 2 can clean the operation with treating clean surface contact in order to treat clean surface, and when need not clean, brush hair 21 of brush hair subassembly 2 can break away from with treating clean surface, and prevents that brush hair 21 from causing secondary pollution to the clear surface. It is understood that the cleaning robot to which the edge brush mechanism in this embodiment is applicable is not limited to a specific type of device, and may be a sweeping robot, a sweeping and mopping integrated robot, a vacuum cleaner, or a sweeping and washing integrated robot.

In the embodiment of the present invention, as shown in fig. 1 to 7, the edge brush mechanism is applied to a cleaning robot, and the cleaning robot includes a housing 1, and the edge brush mechanism includes a driving member (not shown) and a brush component 2.

The driving member is rotatably disposed on the housing 1, and a rotation axis (as shown in fig. 2) of the driving member is disposed obliquely with respect to a bottom surface of the housing 1.

The bristle assembly 2 comprises bristles 21 and a brush holder 22 for connecting the bristles 21, the brush holder 22 is disposed on the housing 1 and connected to a driving member for driving the bristle assembly 2 to rotate around a rotation axis.

The bristle sub-assembly 2 has a first state and a second state; wherein, in the first state, the bristle sub-assembly 2 is continuously rotated; in the second condition, the bristle sub-assembly 2 ceases to rotate and is restrained in a disengaged position (position shown in figure 7) in which the bristles 21 are disengaged from the surface to be cleaned.

In this embodiment, the side brush mechanism is disposed at the bottom of the housing 1 of the cleaning robot, the driving member can drive the bristle assembly 2 to rotate, the rotation axis of the driving member is disposed obliquely with respect to the bottom surface of the housing 1, so that the bristle assembly 2 also rotates around the oblique rotation axis, and the rotation surface of the bristle assembly 2 is oblique to the surface to be cleaned. The brush hair component 2 comprises brush hair 21 and a brush seat 22, the brush seat 22 is connected with the driving part, the brush hair 21 is connected with the brush seat 22, and when the driving part drives the brush seat 22 to rotate, the brush hair 21 can be driven to rotate, so that the brush hair 21 can be in contact with the surface to be cleaned, and the function of cleaning the dirt on the surface to be cleaned is realized. The bristle sub-assembly 2 has a first condition in which the bristle sub-assembly 2 can continue to rotate to contact the surface to be cleaned for cleaning and a second condition in which the bristle sub-assembly 2 can stop rotating and is restrained to a disengaged position in which the bristles 21 disengage from the surface to be cleaned to prevent secondary contamination of the surface being cleaned by the bristle sub-assembly 2.

It should be noted that, the connection between the driving member and the brush seat 22 means that the driving member is connected to at least a portion of the brush seat 22, and the brush seat 22 can be driven to rotate by the driving force of the driving member.

The first state of the brush hair component 2 is equivalent to the normal cleaning state of the side brush mechanism, and at the moment, the driving component drives the brush seat 22 to rotate so as to drive the brush hair 21 to continuously rotate along the inclined rotation axis, so that the brush hair 21 can be contacted with the surface to be cleaned to realize cleaning in the rotation process. The second state of the brush hair component 2 is equivalent to the state that the side brush mechanism stops cleaning, at this time, the brush seat 22 stops driving the brush hair 21 to rotate, and the brush hair 21 is positioned at the separation position separated from the surface to be cleaned, so that the secondary pollution to the cleaned surface is prevented.

In practical applications, the switching structure of the bristle assembly 2 between the first state and the second state may be determined according to practical situations, for example, a limiting structure may be provided on the driving member, such that when the bristles 21 of the bristle assembly 2 are disengaged from the surface to be cleaned, the limiting structure limits the rotation of the driving member, so that the bristles 21 stop at the disengaged position; alternatively, a limiting structure may be provided on the housing 1, such that when the bristles 21 of the bristle assembly 2 are disengaged from the surface to be cleaned, the limiting structure limits the rotation of the bristles 21, so that the bristles 21 stop at the disengaged position; alternatively, the rotation of the brush 21 may be stopped by directly controlling the driving member to stop by an electric control without providing a restriction structure, so that the brush is stopped at the disengaged position, or the like. The specific switching structure may be determined according to actual situations, and may not be limited herein.

In practical applications, the specific structure of the bristle assembly 2 may be determined according to practical situations, such as a single bristle 21 structure, a double bristle 21 structure, or a multiple bristle 21 structure, and the like, and the structure is not limited herein as long as it can be ensured that the cleaning device can smoothly contact with the ground when cleaning is needed, and can be maintained in a state of being separated from the ground when cleaning is not needed. Alternatively, the number of bristles 21 of the bristle sub-assembly 2 may be one, two or more. Since the rotation axis of the bristle sub-assembly 2 is inclined with respect to the bottom surface of the housing 1, the bristles 21 can smoothly contact and clean the surface to be cleaned during the continuous rotation in the first state, that is, the cleaning function can be achieved without being limited to the number of the bristles 21. When the number of the brush hairs 21 is one in the second state, the rotation of the brush hairs 21 can be stopped when the brush hairs 21 rotate to a side close to the machine shell 1, so that the brush hairs 21 are positioned to be separated from the surface to be cleaned; when there are two or more bristles 21, the two or more bristles 21 may be contained or folded at a side close to the housing 1, and the rotation is stopped, so that the bristles 21 are located at a position separated from the surface to be cleaned. Of course, in practice, two or more bristles 21 provide a better cleaning effect on the surface to be cleaned than one bristle 21.

Alternatively, the driving member may employ a motor.

The utility model discloses among the technical scheme limit brush mechanism, brush hair subassembly 2 includes brush hair 21 and brush seat 22, and brush seat 22 is connected with the driving piece for the driving piece can drive brush seat 22 and rotate around the rotation axis of driving piece, and the rotation axis of this driving piece sets up for the bottom surface slope of casing 1, then brush seat 22 can drive brush hair 21 and rotate around the rotation axis that the slope set up, thereby makes brush hair 21 can realize cleaning the function with treating clean surface contact when rotatory. Meanwhile, the bristle assembly 2 in the embodiment has a first state and a second state, the bristle assembly 2 can continuously rotate to clean the surface to be cleaned in the first state, can stop rotating in the second state, and is limited to be located at a separation position where the bristles 21 are separated from the surface to be cleaned, so that the bristle assembly 2 can be in contact with the surface to be cleaned to clean when cleaning is needed, and the bristle assembly 2 can be separated from the surface to be cleaned when cleaning is not needed, so that the bristle assembly 2 is prevented from causing secondary pollution to the cleaned surface.

In an embodiment of the present invention, the brush 21 can be stopped by the stopping member 3 to be restricted from rotating. Illustratively, referring to fig. 1 to 7, the side brush mechanism further includes a retaining member 3 disposed on the housing 1 (including directly disposed on the housing 1 or indirectly disposed on the housing 1), the retaining member 3 is used for retaining the bristle assembly 2, so that the bristles 21 are limited to the disengaged position.

It should be noted that, in some embodiments, the resisting member 3 may be directly disposed on the bottom surface of the casing 1. In other embodiments, the stopping element 3 may be disposed on a fixed part of the housing 1 to be indirectly disposed on the housing 1, for example, the driving element may include a fixed part fixedly connected to the housing 1 and a rotating part for driving the bristle assembly 2 to rotate, the fixed part is fixedly connected to the housing 1, and the stopping element 3 may be disposed on the fixed part of the driving element to be indirectly disposed on the housing 1.

In this embodiment, the abutting member 3 is disposed on the housing 1, and the rotation of the bristle assembly 2 is limited by the abutting member 3, so that the bristles 21 can be simply and reliably located at a position separated from the surface to be cleaned, and the purpose of preventing the bristles 21 from secondarily contaminating the cleaned surface is achieved.

The specific structure of the stop 3 may be determined according to the actual situation. If the stopper 3 is fixed to the housing 1 or movably disposed on the housing 1, the bristle assembly 2 may be limited according to the structure of the stopper 3, if the stopper is fixed, the inclined surface may be designed to have an inclined manner and an inclined angle capable of guiding the movement of the bristles 21, or the stopper may be designed to have a structural form of stopping the movement of the bristles 21, so that the bristle assembly 2 can be switched between the first state and the second state. When the stopper 3 is of a movable structure, it can be accommodated in the housing 1 in the first state, or it can be retracted as appropriate in the housing 1 as long as it does not affect the rotation of the brush 21. And in the second state, the resisting piece 3 extends out of the shell 1 to block the bristle component 2. The specific structure thereof may not be limited herein.

Further, the stopper 3 is located on the side where the rotation axis is inclined downward, and the projection of the rotation axis on the bottom surface of the housing 1 passes through the position of the stopper 3.

As shown in fig. 2, "downward" refers to a direction away from the bottom surface of the casing 1. And the side where the rotation axis is inclined downward means the side where the rotation axis is in a direction away from the bottom surface of the casing 1 and forms an acute angle with the bottom surface of the casing 1.

The purpose of the stop member 3 in the present invention is to stop the bristle assembly 2 and to allow the bristles 21 to be detached from the surface to be cleaned. The bristles 21 are located at the side of the rotation axis inclined downwards in the disengaged position, and the bristle assembly 2 can be stopped at the side of the rotation axis inclined downwards by arranging the stopper 3 at the side of the rotation axis inclined downwards in the present embodiment, so that the bristles 21 are maintained at the disengaged position.

In order to further ensure that the surface to be cleaned is prevented from being secondarily polluted by the bristles 21, the projection of the rotation axis on the bottom surface of the machine shell 1 is arranged through the position of the resisting piece 3, so that when the components of the bristles 21 are resisted by the resisting piece 3, the distance between the bristles 21 and the surface to be cleaned can be maximized, the contact risk between the bristles 21 and the surface to be cleaned is further reduced, and the cleaning effect of the cleaned surface is maintained.

Optionally, the bristle assembly 2 is disposed at the bottom of the casing 1, and its main purpose is to sweep the edge region of the surface to be cleaned or the dirt and garbage at the outer edge of the casing 1 toward the inner side of the casing 1, so that the dirt and garbage can be absorbed by the dust suction opening of the casing 1. On this basis, the contact area of the brush 21 with the surface to be cleaned can be arranged at a position close to the edge of the housing 1 or at a position protruding from the edge of the housing 1, while the rotation axis of the brush 21 is inclined towards the edge of the housing 1, so as to ensure the cleaning purpose of the brush 21 on the surface to be cleaned.

In some embodiments, the number of the bristle assemblies 2 may be two, the two bristle assemblies 2 may be symmetrically disposed at the bottom of the housing 1, and the dust suction opening may be located at the bottom of the housing 1 and located between the two bristle assemblies 2, the two bristle assemblies 2 may rotate in opposite directions, so as to sweep the garbage at two sides to the vicinity of the dust suction opening at the middle part, and finally suck the garbage into the dust box on the robot under the effect of the dust suction force. By arranging the stop member 3 on the side where the rotation axis extends downward, when the brush 21 is stopped by the stop member 3, the brush 21 of the brush unit 2 can be separated from the cleaning surface, so as to avoid secondary pollution to the cleaning surface.

In an embodiment of the present invention, referring to fig. 1 to 7, the driving member can drive the bristle assembly 2 to rotate in a first direction or a second direction, and the first direction is opposite to the second direction. The stop member 3 comprises a guide surface 31 and a stop surface 32, the guide surface 31 being adapted to be passed over by the bristles 21 when the bristle sub-assembly 2 is rotated in the first direction; when the bristle sub-assembly 2 is rotated in the second direction, the blocking surface 32 is adapted to abut the bristles 21 and prevent the bristle sub-assembly 2 from rotating.

In some embodiments, the edge brush mechanism may be disposed at the bottom of the housing 1 of the cleaning robot, and the driving member may drive the bristle assembly 2 to rotate in the first direction or the second direction. The stop member 3 has a guide surface 31 and a blocking surface 32, and illustratively, the guide surface 31 and the blocking surface 32 may be respectively located at both sides of the bristle sub-assembly 2 in the circumferential direction, and the guide surface 31 and the blocking surface 32 are deviated from each other. When the brush 21 rotates to contact with the guide surface 31, the brush can smoothly pass over the guide surface 31, and the normal cleaning work of the brush 21 is ensured. When the brush 21 rotates to contact with the blocking surface 32, the brush is blocked by the blocking surface 32 and cannot rotate continuously, and the brush 21 is separated from the surface to be cleaned, so that the effect of preventing the brush 21 from secondarily polluting the cleaned surface is achieved.

It will be appreciated that the guide surface 31 and the blocking surface 32 correspond to the movement of the bristle sub-assembly 2 from different rotational directions, respectively, and when the bristle sub-assembly 2 is rotated in a first direction, it will contact the guide surface 31 in the path of the movement of the bristles 21 and can smoothly pass over the guide surface 31; when the bristle sub-assembly 2 is rotated in a second direction opposite to the first direction, it contacts the blocking surface 32 in the moving path of the bristles 21 and is blocked by the blocking surface 32.

The following describes different operating states of the cleaning robot:

referring to fig. 2 to 4, when the cleaning robot needs to clean the floor, the driving member drives the bristle assembly 2 to rotate in the first direction, the bristles 21 can smoothly pass over the guide surface 31 of the stopper 3, and the bristles 21 can smoothly contact the surface to be cleaned at least in a partial rotation region due to the inclined arrangement of the rotation axis, and perform a cleaning action.

Referring to fig. 5 to 7, after the cleaning robot finishes sweeping and needs to perform other cleaning operations on the cleaning surface, the driving member drives the bristle assembly 2 to rotate in the second direction, the bristles 21 are blocked by the blocking surface 32 when moving to the blocking surface 32 of the blocking member 3, the driving member stops working, and at this time, the bristles 21 stay at the blocking surface 32, and due to the inclined arrangement of the rotation axis, the bristles 21 can be maintained in a state of being separated from the cleaning surface, thereby avoiding secondary pollution on the cleaning surface, and enabling the cleaning robot to perform other cleaning operations smoothly.

In some other embodiments, the blocking member 3 is telescopically arranged in the housing 1. When the bristle assembly 2 is in the first state, the resisting piece 3 retracts to a preset position along the direction departing from the surface to be cleaned to avoid the bristle assembly 2, or the bristle assembly 2 can pass over the resisting piece 3; in the second state of the bristle sub-assembly 2, the stop 3 projects towards the surface to be cleaned, so as to be able to stop the bristle sub-assembly 2.

When the blocking member 3 is telescopically disposed in the housing 1, the shape of the blocking member 3 may not be limited, and may be any shape, such as a column, a block, or even a sphere.

In some embodiments, the extending and retracting of the abutting element 3 may be realized by driving the abutting element 3 to move through a power mechanism, and for example, the abutting element 3 may be driven to extend and retract relative to the housing 1 by a linear driving element (e.g., a linear motor). Or the driving element (e.g. a rotating motor) can be rotated to drive the stopping element 3 to swing on the casing 1, and in terms of appearance, the stopping element 3 can be extended and retracted relative to the casing 1, specifically, when the driving element 3 is at the highest point of swing, the stopping element 3 can be extended into the casing 1, and when the driving element 3 is at the lowest point of swing, the stopping element 3 can be extended out of the casing 1.

In other embodiments, bristles 21 may comprise rigid bristle arms (not shown) connected to holder 22 and flexible bristle portions connected to the bristle arms, and retainer 3 may be connected to housing 1 by an elastic member (e.g., a spring or rubber). The shape of the stop member 3 can be as described in the above embodiments, and includes the guide surface 31 and the stop surface 32, the guide surface 31 can be a slope or a curved surface, and the rigid bristle arm can push the guide surface 31 during the rotation of the bristles 21, so that the stop member 3 retracts toward the housing 1 and can be stopped by the stop surface 32.

When the stopper 3 is floatably coupled to the housing 1 by the elastic member, the bristle set 2 has less resistance when passing over the stopper 3, so that the rotation during normal cleaning is smoother.

It should be noted that when the blocking member 3 can extend and contract relative to the housing 1 and the blocking member 3 is driven by the power mechanism to extend and contract, the switching of the bristle assembly 2 between the first state and the second state may not depend on the forward rotation and the reverse rotation of the bristle assembly 2. The power mechanism can control the bristle assembly 2 to be in the first state or the second state according to a control signal (which can be a control signal for retracting or putting down the bristle assembly 2 according to the requirement triggered by a user, or a control signal for retracting or putting down the bristle assembly 2 preset by a robot). For example, the blocking member 3 can be controlled to extend from the housing 1 after receiving a control signal for retracting the bristle assembly 2, so as to block the bristle assembly 2 from continuing to rotate, so that the bristles 21 of the bristle assembly 2 are maintained in a position away from the surface to be cleaned. After receiving a control signal that the bristle assembly 2 needs to be put down, the stop member 3 is controlled to retract towards the housing 1, so that the stop action on the bristles 21 can be canceled, the bristles 21 can be in contact with the surface to be cleaned, and the surface to be cleaned is cleaned in the continuous rotation process.

In this embodiment, the abutting member 3 is configured to be a retractable structure, and when the bristle assembly 2 is in the first state, that is, when the side brush mechanism is in the cleaning state, the abutting member 3 can be retracted to a predetermined position to avoid the bristle assembly 2, so that the bristle assembly 2 can continuously rotate to clean the surface to be cleaned; when the bristle component 2 is in the second state, that is, the side brush mechanism is in the state of stopping cleaning, the resisting part 3 extends out of the casing 1 to resist the bristle component 2, so that the bristles 21 are in the separated position, and secondary pollution to the cleaning surface is prevented.

In an embodiment of the present invention, referring to fig. 1 to 7, the brush seat 22 includes an active seat 23 and at least one passive seat 24, and the active seat 23 and the passive seat 24 are coaxially disposed; the driving seat 23 is connected with the driving member, and the driven seat 24 can be driven by the driving seat 23 to rotate.

The brush hairs 21 comprise at least two, and the brush hairs 21 are arranged on the driving seat 23 and at least one driven seat 24, or the brush hairs 21 are arranged on at least two driven seats 24.

In the first state, the bristle sub-assembly 2 is in the extended position, and the included angle between the bristles 21 is a first included angle.

In the second state, the bristle sub-assembly 2 is in the closed position, and the included angle between the bristles 21 is a second included angle.

Wherein the first included angle is larger than the second included angle.

It can be understood that the driving seat 23 is connected to the driving member, and the driven seat 24 is driven by the driving seat 23 to rotate, so that the bristles 21 can be disposed on the driving seat 23 and/or the driven seat 24, and for better cleaning effect, the number of the bristles 21 is at least two, and at least two can be two (as shown in fig. 1 to 7) or more (as shown in fig. 8, 3 bristles 21). When there are two bristles 21, they may be respectively disposed on the active seat 23 and one passive seat 24, and when there are more than two bristles 21, they may be disposed on the active seat 23 and at least two passive seats 24, for example, when there are three bristles 21, they may be disposed on the active seat 23 and two passive seats 24 (as shown in fig. 8), and when the bristle assembly 2 rotates one circle, each bristle 21 can sweep the surface to be cleaned.

On the basis of at least two brush hairs 21, in this embodiment, when brush hair subassembly 2 is in the first state, let brush hair subassembly 2 be in and expand the gesture to make the contained angle between each brush hair 21 be first contained angle, thereby guarantee better cleaning effect, promoted and cleaned efficiency. When the bristle component 2 is in the second state, the bristle component 2 is in the furled posture, so that the included angle between the bristles 21 is a second included angle smaller than the first included angle, and the bristle component 2 is furled in the position of the resisting part 3 to ensure that the bristles 21 are separated from the cleaning surface.

In practical applications, the size of the first included angle may be related to the number of the bristles 21, and a plurality of bristles 21 may be uniformly arranged, for example, when there are 2 bristles 21, the first included angle may be 180 ° (see fig. 3); when there are 3 bristles 21, the first included angle may be 120 ° (see fig. 8); when the number of the bristles 21 is 4, the first included angle may be 90 ° or the like.

In an embodiment of the present invention, referring to fig. 1 to 7, the side brush mechanism further includes a limiting component 25, the limiting component 25 is disposed on the driving seat 23 and the at least one driven seat 24, and is used for supporting the driven seat 24 in the rotation process of the driving seat 23, so as to drive each driven seat 24 to rotate along with the driving seat 23.

In this embodiment, position and structure of the driving seat 23 and the driven seat 24 are limited by the limiting component 25, so that when the bristle component 2 is in the first state, the limiting component 25 can be driven by the driving seat 23 to abut against the driven seat 24, so that the driven seat 24 rotates along with the driving seat 23, and further the bristles 21 on the driving seat 23 and the driven seat 24 are driven to rotate together, thereby cleaning the surface to be cleaned. Or, when the bristle assembly 2 is in the second state, the limiting assembly 25 can abut against the driven seat 24 under the driving of the driving seat 23, so that the driven seat 24 rotates to be folded or is accommodated in the abutting part 3 along with the driving seat 23, and the separation from the cleaning surface is realized.

Alternatively, when the driving base 23 rotates in the first direction, the limiting component 25 moves to abut against the driven base 24 and pushes the driven base 24 to rotate in the first direction, so that the bristles 21 can pass over the guide surface 31 to clean the surface to be cleaned smoothly. When the driving base 23 rotates in the second direction, the limiting component 25 will move to abut against the driven base 24 and push the driven base 24 to rotate in the second direction, so that the bristles 21 are blocked by the blocking surface 32 to maintain the state of being separated from the cleaning surface.

In practical applications, the specific structure of the limiting component 25 may be determined according to actual situations, such as limiting protrusions disposed on the active seat 23 and the at least one passive seat 24, a snap-fit structure at an end of the active seat 23, and the like.

In one embodiment, the position-limiting assembly 25 includes a first position-limiting portion 251 and a second position-limiting portion 252; the first limiting part 251 is used for pushing the driven seat 24 along the first direction in the process that the driving seat 23 rotates along the first direction, so that the bristle component 2 continuously rotates in the unfolding posture and is in the first state; the second limiting portion 252 is used for pushing the driven seat 24 along the second direction in the process that the driving seat 23 rotates along the second direction until the bristle assembly 2 is stopped by the stopping member 3 in the closed posture and is in the second state.

It is understood that the first position-limiting portion 251 and the second position-limiting portion 252 may be protrusions disposed on the driving seat 23, and the distribution positions of the first position-limiting portion 251 and the second position-limiting portion 252 may not be limited herein, for example, the first position-limiting portion 251 and the second position-limiting portion 252 may be disposed on two sides of the same diameter of the driving seat 23, or may be disposed on two points of the trisection point of the driving seat 23, or may be disposed on two points of the tetrasection point of the driving seat, or may be irregularly disposed on two positions of the outer periphery of the driving seat 23.

It can be understood that, when the active seat 23 rotates in the second direction until the second limiting portion 252 moves to abut against the passive seat 24, the active seat 23 and the passive seat 24 are blocked at the blocking surface 32 together, so as to ensure that the bristles 21 on the active seat 23 and the passive seat 24 both leave the ground, and prevent the cleaned ground from being polluted.

In an embodiment of the present invention, referring to fig. 1 to 7, the brush 21 on the active seat 23 is disposed adjacent to the second limiting portion 252 on the active seat 23.

Based on the foregoing embodiments, it can be understood that the first position-limiting portion 251 is located at a position where the driving seat 23 is far away from the bristles 21 on the driving seat 23, when in the first state, the first position-limiting portion 251 abuts against the driven seat 24, and at this time, the driving seat 23 and the driven seat 24 are in the unfolded posture, so as to contact with the surface to be cleaned more quickly, thereby ensuring the cleaning effect. When the cleaning machine is not used for cleaning, the second limiting part 252 is abutted against the driven seat 24, and the bristles 21 of the driven seat 23 and the driven seat 24 are arranged close to or overlapped to be accommodated in the blocking surface 32, so that the surface cleaning effect is better ensured.

In an embodiment of the present invention, referring to fig. 1 to 7, the limiting component 25 is an arc-shaped protrusion or a fan-shaped protrusion with the rotation axis as the center, and the first limiting portion 251 and the second limiting portion 252 are respectively formed as two ends of the arc-shaped protrusion or the fan-shaped protrusion in the circumferential direction.

In this embodiment, spacing subassembly 25 can set up at initiative seat 23, is arc or fan-shaped protruding structure simultaneously, and first spacing portion 251 and the spacing portion 252 of second are the both ends of the protruding circumference direction of arc or fan-shaped protruding respectively, have further increased the structural strength of initiative seat 23, have also strengthened spacing subassembly 25's spacing intensity simultaneously.
