Specifically, as shown in fig. 1 to 5, one embodiment of the present invention provides an edge brush structure. The edge brush structure may be mounted in a floor scrubbing apparatus. The floor cleaning appliance can be, for example, an off-road sweeper. For example, the edge brush structure is used in a floor washing machine. Of course, the structure of the side brush is not limited to be applied to road sweeper, and can also be applied to other ground cleaning equipment, and the application is not limited to this. The present application takes a floor scrubber as an example for explanation.

This limit brush structure includes: the brush disc device comprises a brush disc assembly 11 and a link mechanism 16, one end of the link mechanism 16 is used for being connected with the floor cleaning equipment, and the other end of the link mechanism 16 is rotatably provided with the brush disc assembly 11; the brush disc device is provided with a working position and a non-working position, in the working position, the connecting rod mechanism 16 opens the brush disc assembly 11, and the brush disc assembly 11 cleans the ground; the link mechanism 16 can lift the brush disc assembly 11 and rotate towards the floor cleaning device, and when the working position is switched to the non-working position, the brush disc assembly 11 realizes a process that the telescopic edge lifts upwards after the telescopic action of rotating towards the floor cleaning device through the link mechanism 16; and the control device 14 comprises a traction assembly and a push rod assembly 27, one end of the traction assembly is connected with the connecting rod mechanism 16, the other end of the traction assembly is connected with the push rod assembly 27, and the push rod assembly 27 drives the connecting rod mechanism 16 to move through the traction assembly, so that the brush disc device can horizontally rotate and vertically lift, and the brush disc device can be converted between the working position and the non-working position.

The technical scheme shows that: the edge brush structure of the embodiment of the present invention is provided with a brush tray device including a brush tray assembly 11 and a link mechanism 16, and a control device 14. The control device 14 includes a traction assembly and a push rod assembly 27. When the floor cleaning equipment passes through the narrow space, the push rod assembly 27 can drive the connecting rod mechanism 16 to move so that the brush disc device can move from the working position to the non-working position, and the passing performance of the side brush structure in the narrow space is improved. When the floor cleaning appliance is performing a sweeping operation, the traction assembly can be caused to drive the linkage 16 via the push rod assembly 27 to move the brush disc arrangement from the inoperative position to the operative position, and since in the operative position the linkage 16 is rotated towards the outside of the floor cleaning appliance to open the brush disc assembly 11, the width of the edge brush arrangement to be swept can be increased by rotating the linkage 16. Therefore, the side brush cleaning width of the floor cleaning equipment can be automatically stretched and opened within a reasonable range. Further, when the floor cleaning appliance is not in need of sweeping, the traction assembly drive linkage 16 may be moved by the push rod assembly 27 to enable the brush disc arrangement to move from the active position to the inactive position. Furthermore, the brush disc assembly 11 and the push rod assembly 27 are flexibly and movably connected through the link mechanism 16 and the traction assembly, and the brush disc assembly 11 can be passively contracted or lifted under the action of external force, so that the structure is simple, the cost is low, and the avoiding effect is good.

In this embodiment, at least one of the brush disk devices is provided. The at least one may be 1 or two. The brush disc arrangement comprises a brush disc assembly 11 and a linkage 16. The brush disk assembly 11 includes a brush disk 13 and brushes 15 circumferentially disposed on an outer edge of the brush disk 13. As shown in fig. 3, 4, and 5, for example, the brush plate 13 is circular as a whole. Of course, the brush plate 13 is not limited to a circular shape, but may have other shapes, such as a square shape, and the like. Further, the brush 15 is provided on the bottom surface of the brush plate 13. The brush 15 is used to contact with a surface to be cleaned so that the surface to be cleaned can be cleaned. The surface to be cleaned may be, for example, a floor surface. Of course, the surface to be cleaned is not limited to the floor, but may be other surfaces, and the application is not limited thereto. Further, the brush 15 is made of an elastic material.

In this embodiment, one end of the linkage 16 is used to connect to a floor scrubbing apparatus. In particular, the floor scrubbing apparatus is provided with a chassis 25. One end of the linkage 16 is adapted to be connected to the frame 25. The connection means may be screw connection, bolt connection, welding, integral molding, etc., and this application does not intend to be limited thereto.

In the present embodiment, the other end of the link mechanism 16 is rotatably mounted with the brush tray assembly 11. In this way, the brush disc assembly 11 can rotate relative to the linkage 16, and the brush 15 can clean the surface to be cleaned. Further, the brush disc device has an operative position and an inoperative position. In the operative position, the linkage 16 opens the brush disc assembly 11. Specifically, in the working position, the link mechanism 16 drives the brush disc assembly 11 to rotate towards the outside of the floor cleaning device so that the brush disc assembly 11 can move to the side of the floor cleaning device, and thus the brush 15 can clean the surface to be cleaned. For example, as shown in FIG. 1, in the operative position, the linkage 16 rotates the brush plate assembly 11 out of the page, and in the inoperative position, the linkage 16 lifts and rotates the brush plate assembly 11 toward the floor care appliance. In particular, in the inoperative position, the linkage 16 rotates towards the inside of the floor scrubbing apparatus to enable retraction of the brush disc assembly 11 and/or lifting of the brush disc assembly 11.

Specifically, as shown in fig. 4, the other end of the first link 17 is hinged to the second link 18 by a first pivot 49 so that the second link 18 can rotate up and down relative to the first link 17. Further, the end of the second link 18 remote from the first link 17 is hinged to a third link 19, so that the third link 19 can rotate in the horizontal direction relative to the second link 18. Specifically, as shown in fig. 4, an end of the second link 18 away from the first link 17 is hinged to the third link 19 by a second pivot 51, so that the third link 19 can rotate in the horizontal direction with respect to the second link 18. Further, the brush disc assembly 11 is rotatably mounted on an end of the third link 19 remote from the second link 18. Further, the three-link mechanism 16 employed in the present embodiment enables the cleaning width of the side brush structure to be smaller than that of the four-link mechanism 16.

EXAMPLE III

As shown in fig. 5, in the present embodiment, the link mechanism 16 is a four-bar link mechanism 16. Specifically, the link mechanism 16 includes a first link 17, a second link 18, a third link 19, and a fourth link 21. One end of the first link 17 is adapted to be connected to a chassis 25 of the floor scrubbing apparatus. The connection means may be screw connection, bolt connection, welding, integral molding, etc., and this application does not intend to be limited thereto. Further, the other end of the first link 17 is hinged to a second link 18 so that the second link 18 can be rotated up and down with respect to the first link 17. Specifically, as shown in fig. 5, the other end of the first link 17 is hinged to the second link 18 by a first pivot 49 so that the second link 18 can rotate up and down relative to the first link 17. Further, the end of the second link 18 away from the first link 17 is hinged to the third link 19, so that the third link 19 can rotate up and down relative to the second link 18. Specifically, as shown in fig. 5, the end of the second link 18 away from the first link 17 is hinged to the third link 19 via a second pivot 51, so that the third link 19 can rotate up and down relative to the second link 18. Further, the end of the third link 19 away from the second link 18 is hinged to the fourth link 21, so that the fourth link 21 can rotate in the horizontal direction relative to the third link 19. Specifically, as shown in fig. 5, an end of the third link 19 away from the second link 18 is hinged to the fourth link 21 by a third pivot 52, so that the fourth link 21 can rotate in the horizontal direction relative to the third link 19. Further, the brush disc assembly 11 is rotatably mounted on an end of the fourth link 21 remote from the third link 19. Further, the four-link mechanism 16 employed in the present embodiment makes the cleaning width of the side brush structure larger than that of the three-link mechanism 16.

In this embodiment, the control device 14 includes a traction assembly and a push rod assembly 27. One end of the pulling assembly is connected to a linkage 16. The other end of the traction assembly is connected to a push rod assembly 27. Therefore, the brush disc assembly 11 and the push rod assembly 27 are flexibly and movably connected through the connecting rod mechanism 16 and the traction assembly, and the brush disc assembly 11 can be passively contracted or lifted under the action of external force, so that the structure is simple, the cost is low, and the avoiding effect is good.

Further, the push rod assembly 27 is used to drive the movement of the linkage 16 through the traction assembly to enable the brush disc arrangement to be converted between the active and inactive positions. Specifically, when the brush disc device is in the working position, the push rod assembly 27 drives the traction assembly to move, so that the connecting rod mechanism 16 drives the brush disc assembly 11 to rotate towards the outer side of the ground cleaning equipment, and then the brush disc assembly 11 is opened, thereby eliminating the positioning error and meeting the requirement of welt cleaning. When the brush disc device is in the non-working position, the connecting rod mechanism 16 enables the brush disc component 11 to be lifted and rotate towards the ground cleaning equipment, so that the ground cleaning equipment can be ensured to pass through a narrow space; and when cleaning is not needed, the side brush structure can be automatically contracted and lifted. Therefore, the side brush cleaning width of the floor cleaning equipment can be automatically stretched and opened within a reasonable range. Further, the push rod assembly 27 includes a driving motor and an electric push rod 28 in transmission connection with a rotating shaft of the driving motor.

In one embodiment, the pulling assembly includes a first wire 30 mechanism and a second wire 31 mechanism. The first wire pulling 30 mechanism and the second wire pulling 31 mechanism are used for respectively driving the connecting rod mechanism 16 to rotate and lift, so that the connecting rod mechanism 16 can drive the brush disc device to rotate and lift.

Specifically, the first wire 30 mechanism includes a first link 29 and a first wire 30. The first connector 29 is connected to the push rod assembly 27. More specifically, the first link 29 is connected to the electric push rod 28. In the present embodiment, the first connecting member 29 is a first connecting pin. The electric push rod 28 is provided with a through hole. The first connecting pin is arranged in the through hole in a penetrating mode. Further, both ends of the first wire 30 are connected to the first link 29 and the link mechanism 16, respectively. Specifically, in the present embodiment, there are two brush plate devices. The two brush disc arrangements are located on opposite sides of the chassis 25 of the floor scrubbing apparatus. The two brush disc devices are respectively used for cleaning two sides of the floor cleaning equipment. Further, the number of the first wires 30 is two. One end of each first wire 30 is connected to one end of the first connecting member 29, respectively. For example, as shown in fig. 2, two first wires 30 are connected to both ends of the first connecting member 29. Further, the other end of each first pull wire 30 is connected to two linkages 16 located on opposite sides of the floor cleaning appliance rack 25. So that two first wires 30 can connect the linkage 16 of two brush disc arrangements to the first connecting member 29. The left and right link mechanisms 16 are simultaneously rotated by one push rod assembly 27, the design is exquisite, and the manufacturing cost is greatly reduced.

Further, the push rod assembly 27 is used to drive the first pulling wire 30 to move through the first connecting member 29, so that the first pulling wire 30 mechanism can drive the link mechanism 16 to rotate horizontally. Specifically, the driving motor is used to drive the electric push rod 28 to move up and down, so that the electric push rod 28 can drive the first connecting member 29 to move up and down, and the first connecting member 29 can drive the first pulling wire 30 to move, so that the first pulling wire 30 can drive the link mechanism 16 to rotate horizontally. Specifically, in the first embodiment, the first link 17 is provided with the first wire winding portion 53 for passing the first wire 30 therethrough. An end of the fourth link 21 remote from the third link 19 is provided with a first connecting portion 57 for connecting with the first wire 30. For example, the first winding portion 53 is a hook. The first wire 30 thus passes through the first wire winding part 53 and is connected to the end of the fourth link 21 remote from the third link 19. Thus, when the driving motor drives the electric push rod 28 to move upwards, the electric push rod 28 drives the first connecting member 29 to move upwards, and the first pull wire 30 drives the fourth link 21 to rotate around the second pivot 51 towards the first link 17, so that the brush disc device is converted from the working position to the non-working position. When the driving motor drives the electric push rod 28 to move downwards, the electric push rod 28 drives the first connecting member 29 to move downwards, and the first pull wire 30 drives the fourth link 21 to rotate around the second pivot 51 away from the first link 17, so that the brush tray apparatus is converted from the non-working position to the working position. In the second embodiment, the first link 17 is provided with the first wire winding portion 53 for passing the first wire 30 therethrough. An end of the third link 19 remote from the second link 18 is provided with a first connecting portion 57 for connecting with the first wire 30. The first wire 30 thus passes through the first winding portion 53 and is connected to the end of the third link 19 remote from the second link 18. Thus, when the driving motor drives the electric push rod 28 to move upwards, the electric push rod 28 drives the first connecting member 29 to move upwards, and the first pull wire 30 drives the third connecting rod 19 to rotate around the second pivot 51 towards the first connecting rod 17, so that the brush disc device is converted from the working position to the non-working position. When the driving motor drives the electric push rod 28 to move downwards, the electric push rod 28 drives the first connecting member 29 to move downwards, and the first pull wire 30 drives the third connecting rod 19 to rotate around the second pivot 51 away from the first connecting rod 17, so that the brush disc device is converted from the non-working position to the working position. In the third embodiment, the first link 17 is provided with the first wire winding portion 53 for passing the first wire 30 therethrough. An end of the fourth link 21 remote from the third link 19 is provided with a first connecting portion 57 for connecting with the first wire 30. The first wire 30 thus passes through the first wire winding part 53 and is connected to the end of the fourth link 21 remote from the third link 19. Thus, when the driving motor drives the electric push rod 28 to move upwards, the electric push rod 28 drives the first connecting member 29 to move upwards, and the first pull wire 30 drives the fourth link 21 to rotate around the third pivot 52 towards the first link 17, so that the brush disc device is converted from the working position to the non-working position. When the driving motor drives the electric push rod 28 to move downwards, the electric push rod 28 drives the first connecting member 29 to move downwards, and the first pull wire 30 drives the fourth link 21 to rotate around the third pivot 52 away from the first link 17, so that the brush tray apparatus is converted from the non-working position to the working position.

Further, a bracket 33 is mechanically connected to the first wire 30. Specifically, the bracket 33 is connected to the first connecting member 29. So that the first connecting member 29 can drive the bracket 33 to move. More specifically, the bracket 33 includes a first side wall 34 and a second side wall 35 disposed oppositely, and a bottom wall 37 disposed between the first side wall 34 and the second side wall 35. The first side wall 34, the second side wall 35 and the bottom wall 37 enclose a containing space therebetween. Further, the first side wall 34 and the second side wall 35 are connected to the first connector 29. So that the bracket 33 is connected to the first connecting member 29.

Further, the second wire 31 mechanism includes a second connecting member 32 and a second wire 31. The second link 32 is movably disposed on the bracket 33. So that the second link 32 can move relative to the bracket 33. Further, the first side wall 34 and the second side wall 35 are respectively provided with rails 39 extending in the up-down direction. In particular, the rail 39 is a U-shaped groove. The rail 39 is not limited to a U-shaped groove, and may have another configuration, for example, the rail 39 is a through hole, which is not limited in this application. Further, two ends of the second connecting member 32 are respectively inserted into the two rails 39, so that the second connecting member 32 can move along the rails 39 relative to the bracket 33. Further, the rail 39 has a stopper portion 43 facing upward. In the present embodiment, the stopper portion 43 is a groove bottom surface facing upward in the U-shaped groove. The stopping portion 43 is used to abut against the second connecting member 32, so that the bracket 33 can drive the second wire 31 to move through the second connecting member 32. For example, when the second connecting member 32 abuts against the bottom surface of the U-shaped groove, the bracket 33 can move the second connecting member 32.

Further, both ends of the second wire 31 are connected to the second link 32 and the link mechanism 16, respectively. In this embodiment, there are two second wires 31. One end of each second wire 31 is connected to a second connecting member 32. For example, as shown in fig. 2, two second wires 31 are connected to the second connecting members 32, respectively. Further, the other end of each second wire 31 is connected to two linkages 16 located on opposite sides of the floor cleaning appliance rack 25. Such two second wires 31 can connect the linkage 16 of the two brush disc arrangements to the second connecting member 32. Thus, the lifting of the left and right link mechanisms 16 is realized simultaneously through one push rod assembly 27, the design is exquisite, and the manufacturing cost is greatly reduced.

Further, a first elastic member 41 is provided between the second connecting member 32 and the bottom wall 37 of the bracket 33. The first elastic member 41 may be a spring, and is used to ensure that the second pulling wire 31 is always in a stretched state, so as to perform a resetting function. For example, as shown in fig. 2, there are two first elastic members 41, and two second wires 31 are respectively inserted into the two first elastic members 41. Further, both ends of the first elastic member 41 respectively abut against the second connecting member 32 and the bottom wall 37 of the bracket 33, and the first elastic member 41 is adapted to abut against the second connecting member 32 to limit the downward movement of the second connecting member 32. For example, as shown in fig. 2, the second connecting member 32 abuts against two first elastic members 41, so that the second connecting member 32 can be located at the upper end of the U-shaped groove.

Further, the bracket 33 is used for driving the second wire 31 to move through the second connecting member 32, so that the link mechanism 16 can be lifted. Specifically, for example, when the electric push rod 28 drives the bracket 33 to move upward, since the elastic force of the first elastic member 41 on the second connecting member 32 is smaller than the force of the electric push rod 28 on the bracket 33, the bracket 33 can move upward relative to the second connecting member 32, so that the distance between the second connecting member 32 and the bottom wall 37 of the bracket 33 becomes smaller and smaller, and the first elastic member 41 is compressed. When the bottom wall 37 of the bracket 33 moves to abut against the second connecting member 32, the bracket 33 drives the second connecting member 32 to move upward, and at this time, the bracket 33 can drive the second wire 31 to move through the second connecting member 32. Further, the second pulling wire 31 is used for driving the link mechanism 16 to lift and lower. Specifically, in the first, second, and third embodiments, the second connecting portion 59 connected to the second wire 31 is provided on the second link 18. Therefore, when the driving motor drives the electric push rod 28 to move upward until the bottom wall 37 of the bracket 33 abuts against the second connecting member 32, the electric push rod 28 drives the bracket 33 to move upward, and then the bracket 33 drives the second connecting member 32 to move upward, the second connecting member 32 drives the second pull wire 31 to move, and the second pull wire 31 drives the second connecting rod 18 to rotate upward around the first pivot 49 relative to the first connecting rod 17. When the driving motor drives the electric push rod 28 to move downward, since the second connecting member 32 abuts against the bottom wall 37 of the bracket 33, the electric push rod 28 drives the bracket 33 to move downward, so that the bracket 33 drives the second connecting member 32 to move downward, the second connecting member 32 drives the second pull wire 31 to move, and the second pull wire 31 drives the second connecting rod 18 to rotate downward around the first pivot 49 relative to the first connecting rod 17.

It can be understood that, in the actual use process, the side brush structure is installed on the ground cleaning equipment, the side brush structure is controlled according to the sequence of first contraction and then lifting, and the side brush structure is firstly contracted for a certain distance and then lifted, which is determined by the space of the side brush structure inside the ground cleaning equipment, because the side brush structure is positioned at the edge of the shell of the ground cleaning equipment, if the side brush structure is not contracted and lifted, the side brush structure can be blocked by the shell. Wherein the first contracted distance range value is set based on the groove length value range of the track 39. The travel of the second link 32 in the groove of the track 39 is reflected in the side brush structure movement, i.e. in the distance range described above. Still further, the above distance range is set by the spring force of the rail 39 and the first elastic member 41, and by adjusting the spring force of the first elastic member 41 appropriately, it is possible that when the second link 32 does not reach the bottom dead center, the rising force of the push rod assembly 27 overcomes the spring force, so that the second wire 31 pulls the side brush structure to be lifted.

As shown in fig. 2, in one case, each second wire 31 is sleeved with a first elastic member 41 formed of a spring; in another case, the second pull wire 31 is sleeved with a first elastic member 41 formed by a first spring and a second spring which are overlapped, the first spring is arranged inside, the second spring is arranged outside, the two spring forces are different, the elastic force of the second spring on the outside is large, the rigidity is stronger, the elastic force of the first spring on the inside is small, and in the height direction, the first spring is higher than the second spring, so that the pull wire can be kept in a tightening state through the first spring on the inside, and the distance can also be set through the second spring and the groove of the track 39 together.

In one embodiment, the linkage 16 is further provided with a first return spring 45 and a second return spring 47. The first return elastic member 45 and the second return elastic member 47 are both compressed when the brush tray apparatus is shifted from the operating position to the non-operating position, so as to apply elastic force to the link mechanism 16 when the brush tray apparatus is shifted from the non-operating position to the operating position. Further, the first return elastic member 45 and the second return elastic member 47 are compressed when the link mechanism 16 rotates and ascends and descends, respectively, to apply elastic force to the link mechanism 16 when the brush holder device is transferred from the non-operating position to the operating position. In the first and third embodiments, one end of the first return elastic member 45 is connected to the first link 17. The other end of the first return elastic member 45 is connected to the fourth link 21. One end of the second return elastic member 47 is connected to the first link 17. The other end of the second return elastic member 47 is connected to the second link 18. In the second embodiment, one end of the first return elastic member 45 is connected to the first link 17. The other end of the first return elastic member 45 is connected to the third link 19. One end of the second return elastic member 47 is connected to the first link 17. The other end of the second return elastic member 47 is connected to the second link 18.

Further, the operation of the control device 14 of the present invention is as follows:

when the driving motor drives the electric push rod 28 to move downwards to the lowest point, the electric push rod 28 is located at the lowest stroke position. The brush tray device is in the working position. With the brush tray assembly 11 in the open maximum position and the raised minimum position. At this time, the link mechanism 16 is kept in position by the tensile force of the first return elastic member 45 and the second return elastic member 47, and the brush holder assembly 11 is in the welt cleaning operation state. When the floor cleaning equipment needs to pass through a narrow space, the electric push rod 28 starts to retract, the push rod drives the first pull wire 30 to work, the brush disc assembly 11 starts to retract under the connection effect of the first pull wire 30, at the moment, the second pull wire 31 and the second connecting piece 32 slide in the U-shaped groove of the support 33 under the effect of the first elastic piece 41, the spring force of the first elastic piece 41 is smaller than the lifting force of the electric push rod 28, so that the brush disc assembly 11 still keeps the original position and does not lift, the electric push rod 28 continuously works, when the second connecting piece 32 moves to the lowest position of the U-shaped groove of the support 33, the second pull wire 31 starts to drive the link mechanism 16 to start to lift upwards, at the moment, the brush disc assembly 11 is pulled by the first pull wire 30 and the second pull wire 31 to retract inwards and lift upwards at the same time, when the electric push rod 28 retracts to the limit position, the work is stopped, the brush disc assembly 11 retracts to the minimum position, lifting to the highest position, wherein the ground cleaning equipment can smoothly pass through the narrow channel; after the opening of the electric push rod 28 is completed, the first pull wire 30 and the second pull wire 31 are loosened, the brush disc assembly 11 starts to descend and open simultaneously under the acting force of the first return elastic element 45 and the second return elastic element 47, the descending is stopped when the link mechanism 16 moves to the lowest position, the electric push rod 28 continues to work, and the brush disc assembly 11 stops opening after the opening action is continued to the maximum opening position.

Further, the push rod assembly 27 is a hall push rod, and the hall push rod is in transmission connection with the other end of the traction assembly. Initially when the bristle length of the brush disc assembly 11 is 100%, the stroke of the electric putter 28 is set to 60%. When the bristle length of the brush disc assembly 11 is worn to 80%, the electric push rod 28 stroke is set to 80%. When the length of the bristles of the brush disc assembly 11 is long and the bristles are worn to 60%, the stroke of the electric push rod 28 is set to be 100%, one-key operation is achieved, and manual disassembly and adjustment are not needed.
