Description

Technical Field

[0001] The present application relates to an automatic sweeper, and more specifically, to a cleaning component and a cleaning robot. Background Art

[0002] Automatic cleaning robots use roller brushes or disc brushes at the bottom to clean while walking. The rotation or rolling of the brush exerts a certain force on the garbage. In order to prevent the garbage from being brushed out of the robot's cleaning range during the operation of the brush, the roller brush or disc brush is usually enclosed with side rubber strips to prevent water and garbage from splashing. At the same time, during the use of the cleaning robot, the side rubber strips that are in contact with the ground also play a certain cleaning role. However, during the equipment assembly process or as the side rubber strips are worn out during use, the side rubber strips usually do not fit well with the ground, resulting in poor wrapping effect of the side rubber strips on the cleaning range of the roller brush or disc brush, causing water or garbage to be thrown out from the gap between the rubber strips and the ground. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] The cleaning component and cleaning robot of the present application will now be described in detail with reference to the accompanying drawings.

[0037] The cleaning robot provided in the embodiment of the present application is used to automatically clean the ground. The cleaning robot includes a body, a driving wheel arranged at the bottom of the body, and a cleaning component. The driving wheel is used to drive the body to walk on the ground, and the cleaning component is used to clean garbage, moisture, stains, etc. on the ground during the movement of the body.

[0038] Please refer to Figures 1 to 3 The cleaning assembly 100 includes a cleaning brush group 10, a lower seat plate 20, a rubber strip 30, an upper seat plate 40, a movable connecting rod assembly 50 and an adjustment structure 60. Specifically, the lower seat plate 20 is arranged at the periphery of the cleaning assembly 100. The rubber strip 30 is fixedly arranged on the lower seat plate 20 and is used to enclose the cleaning assembly 100. The upper seat plate 40 is fixedly arranged on the cleaning brush group 10 and is arranged above the lower seat plate 20 relative to the ground. The two ends of the movable connecting rod are respectively connected to the lower seat plate 20 and the upper seat plate 40. The adjustment structure 60 is arranged on the upper seat plate 40 and connected to the movable connecting rod assembly 50, and is used to drive the movable connecting rod assembly 50 to move so as to drive the rubber strip 30 on the lower seat plate 20 to move up and down relative to the ground, and can also be used to drive the movable connecting rod assembly 50 to swing relative to the cleaning assembly 100.

[0039] In the above-mentioned cleaning assembly 100, the movable link assembly 50 is driven to move by the adjustment structure 60 to drive the rubber strip 30 on the lower seat plate 20 to move relative to the ground, so that the height of the rubber strip 30 and the ground can be adjusted; and at the same time, the adjustment structure 60 can be used to drive the movable link assembly 50 to swing relative to the cleaning assembly 100, and the swinging movable link assembly 50 can drive the rubber strip 30 to swing relative to the cleaning assembly 100, so that the angle of the rubber strip 30 relative to the cleaning assembly 100 can be adjusted. By adjusting the height position and angle position of the rubber strip 30, the rubber strip 30 arranged around the cleaning assembly 100 can better fit the ground and better surround the cleaning assembly 100, thereby improving the poor fitting effect and wrapping effect of the rubber strip 30 caused by assembly differences and use loss. In this way, the garbage and moisture thrown up by the roller brush assembly can be effectively prevented from escaping from the gap between the rubber strip 30 and the ground, thereby improving the cleaning effect.

[0040] like Figure 1 and Figure 2 As shown, the cleaning brush assembly 10 includes a brush cover 11 and a brush member 12 rotatably disposed on the brush cover 11 for cleaning the floor, and the upper seat plate 40 is connected to the brush cover 11 .

[0041] In one embodiment, the brush member 12 may be two roller brushes arranged in parallel, and a trash box (not shown) is provided on one side of the cleaning brush assembly 10, and the two roller brushes rotate in opposite directions to each other, and the ground garbage or stains are thrown into the trash box by the action of centrifugal force. In this embodiment, except for the side where the trash box is provided, the other sides of the cleaning brush assembly 10 can be provided with a rubber strip 30. The rubber strip 30 can be a whole piece. The rubber strip 30 can also be several pieces arranged at intervals, and each rubber strip 30 has a lower seat plate 20, an upper seat plate 40, and a movable connecting rod assembly 50 to connect the rubber strip 30 to the brush cover 11, and each rubber strip 30 is adjusted by an adjustment structure.

[0042] In another embodiment, the structure of this embodiment is basically the same as the above embodiment, except that the brush member 12 is two disc brushes arranged in parallel and rotating in opposite directions.

[0043] like Figure 3 As shown, the movable link assembly 50 includes a first link 51 and a second link 52 arranged in parallel, the two ends of the first link 51 are respectively movably hinged to the lower seat plate 20 and the upper seat plate 40, and the two ends of the second link 52 are respectively movably hinged to the lower seat plate 20 and the upper seat plate 40. The hinge point of the first link 51 and the lower seat plate 20, the hinge point of the first link 51 and the upper seat plate 40, the hinge point of the second link 52 and the lower seat plate 20, and the hinge point of the second link 52 and the upper seat plate 40 form a parallelogram structure.

[0044] It is worth noting that the aforementioned hinged connection can be a ball hinge or a bearing hinge, both of which are rolling friction. Since the aforementioned four hinge points form a parallelogram structure, when the adjustment structure drives the movable link assembly 50 to move, that is, drives the first link 51 and the second link 52 to swing, so as to realize the movement of the lower seat plate 20 relative to the upper seat plate 40, so as to realize the up and down movement of the rubber strip 30 on the lower seat plate 20, the upper seat plate 40 can be smoothly moved vertically up and down when driving the upper seat plate 40 to move up and down relative to the lower seat plate 20.

[0045] Refer to Figures 4 to 6 As shown, the adjustment structure includes a first adjustment component 61 for adjusting the distance of the rubber strip 30 relative to the ground. Specifically, the first adjustment component 61 includes an adjustment handle 61, a first elastic member 62, a swing rod 63 and a second elastic member 64; one end of the adjustment handle 61 can movably pass through the upper seat plate 40 and then connect to the swing rod 63, and the other end can be buckled on the upper seat plate 40; the swing rod 63 is located on the side of the upper seat plate 40 facing the cleaning brush assembly 10; the first elastic member 62 is used to be compressed between the upper seat plate 40 and the swing rod 63, and the two ends of the second elastic member 64 are respectively connected to the second connecting rod 52 and the swing rod 63.

[0046] In one embodiment, the first elastic member 62 is a compression spring, and the second elastic member 64 is a tension spring.

[0047] It is worth noting that when the first adjustment component 61 adjusts the distance between the rubber strip 30 and the ground, the second elastic member 64 generates different stretching lengths, thereby adjusting the different pressures of the rubber strip 30 on the ground. Furthermore, when the cleaning component 100 encounters an uneven ground and pushes the rubber strip 30 upward during cleaning, due to the elastic effect of the second elastic member 64, the rubber strip 30 can adaptively move upward by an end distance, thereby reducing the damage to the equipment.

[0048] It is worth noting that, under normal circumstances, the first elastic member 62 maintains a certain compression state, so that the adjustment handle 61 is pressed against the upper seat plate 40. During use, the adjustment handle 61 can be pulled out so that the end buckled on the upper seat plate 40 is no longer buckled on the upper seat plate 40, and then the swing rod 63 is driven to rotate by rotating the adjustment handle 61. Since the swing rod 63 and the second connecting rod 52 are connected by the second elastic member 64, the second connecting rod 52 is pulled to move by the second elastic member 64, and the second connecting rod 52 drives the lower seat plate 20 hinged thereto to move, so that the rubber strip 30 on the lower seat plate 20 moves accordingly. In one embodiment, if the adjustment handle 61 is rotated clockwise, the lower seat plate 20 and the upper seat plate 40 are brought closer to each other, that is, the rubber strip 30 moves upward; then, if the adjustment handle 61 is rotated counterclockwise, the lower seat plate 20 and the upper seat plate 40 are moved away from each other, that is, the rubber strip 30 moves downward. In another embodiment, if the adjustment handle 61 is rotated clockwise, the lower seat plate 20 and the upper seat plate 40 move away from each other, that is, the rubber strip 30 moves downward; then, if the adjustment handle 61 is rotated counterclockwise, the lower seat plate 20 and the upper seat plate 40 move closer to each other, that is, the rubber strip 30 moves upward.

[0049] Furthermore, the adjustment handle 61 includes a handle portion 611 and a connecting shaft 612 disposed on the handle portion 611 and used to penetrate the upper seat plate 40. The connecting shaft 612 includes a first shaft portion disposed on the handle portion 611 and a second shaft portion disposed at an end of the first shaft portion away from the handle portion 611, and the second shaft portion is connected to the swing rod 63. In addition, the cross-sectional diameter of the second shaft portion is smaller than the cross-sectional diameter of the second shaft portion; the upper seat plate 40 is provided with a shaft hole (not shown) adapted to the cross-sectional diameter of the first shaft portion.

[0050] It can be understood that when the adjustment handle 61 is not rotated, the shaft hole is penetrated by the first shaft portion, and the shaft hole and the first shaft portion are adapted and fit. Since the cross-sectional diameter of the second shaft portion is smaller than that of the first shaft portion, when the adjustment handle 61 is pulled so that the adjustment handle 61 is no longer locked with one end of the upper seat plate 40, the adjustment handle 61 can be pulled so that the second shaft portion is located in the shaft hole. At this time, compared with when the first shaft portion passes through the shaft hole, when the second shaft portion is located in the shaft hole, it is easier to rotate the adjustment handle 61 smoothly. After the rotation, when the first shaft portion is pushed into the shaft hole again, it is helpful to keep the adjustment handle 61 fixedly set on the upper seat plate 40.

[0051] Further reference Figure 5 and Figure 6 The adjusting handle 61 further includes a block 617 disposed on the handle 611 and snapped onto the upper seat plate 40. The upper seat plate 40 is provided with a plurality of arc-shaped snap holes 41 for inserting the block 617. The block 617 and the connecting shaft 612 may be disposed on the same side of the handle 611.

[0052] It can be understood that the multiple arc-shaped card holes 41 are set on the path of the swing rod 63 as the adjusting handle 61 swings. When the adjusting handle 61 is rotated at different angles, the card blocks 617 are respectively inserted into different card holes 41. The different upward and downward displacements of the rubber strip 30 achieved by rotating the adjusting handle 61 at different angles, and the second elastic member 64 is stretched to different lengths to adjust the different pressures of the rubber strip 30 on the ground. In this way, the cooperation of the multiple card holes 41 and the card blocks 617 can display the segmented position movement of the rubber strip 30.

[0053] Further references Figure 3 The first adjustment assembly 61 further includes a first stopper 618 and a second stopper 619 both disposed on the side of the upper seat plate 40 facing the cleaning brush assembly 10. The plurality of clamping holes 41, the first stopper 618 and the second stopper 619 are all disposed around the shaft hole. The first stopper 618 and the second stopper 619 are disposed at intervals around the end where the swing rod 63 is connected to the connecting shaft 612, and are used to limit the swing rod 63 swinging with the connecting shaft 612 in two opposite directions.

[0054] In one embodiment, the first limit block 618 and the second limit block 619 are arranged in an eight-shaped pattern, and one end of the swing rod 63 connected to the second shaft portion of the connecting shaft 612 is adapted to fit in the eight-shaped region. When the swing rod 63 rotates clockwise within a certain range along with the second shaft portion, the first limit block 618 blocks the swing rod 63 so that it cannot rotate any further, and at this time, the clamping block 617 just clamps into the first clamping hole 41 of the plurality of clamping holes 41 distributed in an arc shape. When the swing rod 63 rotates counterclockwise within a certain range along with the second shaft portion, the second limit block 619 blocks the swing rod 63 so that it cannot rotate any further, and at this time, the clamping block 617 just clamps into the last clamping hole 41 of the plurality of clamping holes 41 distributed in an arc shape.

[0055] Combined with reference 2, Figure 3 and Figure 7 The adjustment structure also includes a second adjustment component 62 for adjusting the angle of the rubber strip 30 relative to the cleaning brush assembly 10 , and the adjustment component 62 includes an adjustment knob 621 , a frame seat 622 and two elastic positioning members 623 .

[0056] Specifically, the upper seat plate 40 is penetrated by a screw 624 threadedly matched therewith, and the adjusting knob 621 and the frame seat 622 are arranged at both ends of the screw 624 penetrating the upper seat plate 40; the frame seat 622 and the screw 624 can be connected in a hinged manner. In addition, the frame seat 622 is arranged on the side of the upper seat plate 40 facing the cleaning brush assembly 10 and is provided with a U-shaped groove 625. Among them, one end of the first connecting rod 51 is arranged in the U-shaped groove 625 and is clamped by two elastic positioning members 623 arranged on both sides of the frame seat 622. Further, the position where the two elastic positioning members 623 clamp the first connecting rod 51, the position where the first connecting rod 51 is hinged with the upper seat plate 40, and the hinged position of the first connecting rod 51 and the lower seat plate 20 are distributed in sequence on the first connecting rod 51.

[0057] When the adjustment knob 621 is turned, the screw 624 drives the frame seat 622 to move in the direction A, and the moving frame seat 622 also applies a force to the first connecting rod 51 located in the U-shaped groove 625 to move in the direction A. Since the first connecting rod 51 is hinged on the upper seat plate 40, the first connecting rod 51 is caused to rotate in the direction B with the hinge point as the fulcrum. Then, driven by the aforementioned force, the rubber strip 30 on the lower seat plate 20 is caused to swing at an angle away from the cleaning brush assembly 10 with the upper seat plate 40 as the fulcrum. Conversely, when the screw 624 drives the frame seat 622 to move in the opposite direction to the direction A, the rubber strip 30 on the lower seat plate 20 is caused to swing at an angle with the upper seat plate 40 as the fulcrum to approach the cleaning brush assembly 10.

[0058] It is worth noting that the elastic positioning member 623 is a spring wave ball, and the head of the spring wave ball is a steel ball. The steel ball parts of the two elastic wave balls are used for the first connecting rod 51. The friction of the steel ball heads of the spring wave balls is rolling friction, and the friction force generated is relatively small. When the first connecting rod 51 swings, the point-to-point contact between the two steel ball surfaces will not cause interference during the movement of the limit seat; and when the first adjustment component 61 drives the first connecting rod 51 and the second connecting rod 52 to swing to drive the rubber strip 30 to move up and down relative to the ground, the rolling friction contact of the steel ball heads of the spring wave balls will reduce the resistance of the second adjustment component 62 to the first connecting rod 51, that is, the resistance to the movement of the rubber strip 30 is minimized.

[0059] like Figure 3 and Figure 4 As shown, the second adjustment assembly 62 further includes a limit plate 626 respectively disposed on the side of the upper seat plate 40 facing the cleaning brush assembly 10, the upper seat plate 40 and the limit plate 626 form an active area, and the frame seat 622 is at least partially disposed in the active area 627. When the adjustment knob 621 is turned, the movement of the frame seat 622 is limited between the limit plate 626 and the upper seat plate 40 along the A direction or the opposite direction to A.

[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
