When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] The utility model provides a side brush mechanism 100, which can be applied to cleaning equipment such as sweepers, floor scrubbers, sweeping and mopping machines, etc. For the convenience of description, the following takes the side brush mechanism 100 applied to sweepers as an example to describe the specific structure of the side brush mechanism 100, and other equipment can refer to the adaptability implementation.

[0047] Specifically, see Figure 1 and Figure 4 In this embodiment, the side brush mechanism 100 includes a substrate 1, a side brush assembly 2, a side brush adjustment assembly 3 and an elastic reset member. The substrate 1 is used for mounting the side brush assembly 2 and the side brush adjustment assembly 3 thereon, so that the entire side brush mechanism 100 is connected to the main body of the sweeper; the side brush assembly 2 is movably arranged on the substrate 1, so as to have a first working position suitable for extending from the sweeper, and a second working position suitable for retracting into the sweeper; the side brush adjustment assembly 3 is connected to the side brush assembly 2, and the side brush adjustment assembly 3 is used to drive the side brush assembly 2 to move from the first working position to the second working position, and can provide a holding force on the side brush assembly 2 so that the side brush assembly 2 is kept at the second working position; the elastic reset member connects the substrate 1 and the side brush assembly 2, and the elastic reset member can provide an elastic reset force for driving the side brush assembly 2 to move from the second working position toward the first working position; when the holding force provided by the side brush adjustment assembly 3 is canceled, the side brush assembly 2 can move from the second working position to the first working position under the action of the elastic reset force of the elastic reset member.

[0048] In the present embodiment, the garbage can be cleaned and pushed by the side brush assembly 2, so that the garbage can be better moved toward the dust suction port of the sweeper; the side brush assembly 2 can be driven to move by the side brush adjustment assembly 3, so that the side brush assembly 2 has a first working position suitable for extending from the sweeper, and a second working position suitable for retracting into the sweeper. When in the first working position, the side brush assembly 2 can be extended from the sweeper, with a larger cleaning range, and the side brush assembly 2 can be better extended into a narrow or low area for cleaning. When in the second working position, the side brush assembly 2 can be better retracted inside the sweeper body, so that the sweeper occupies less space for easy storage; and when the holding force provided by the side brush adjustment assembly 3 is revoked, the side brush assembly 2 can move from the second working position to the first working position under the action of the elastic reset force of the elastic reset member, that is, when the side brush assembly 2 moves from the first working position toward the second working position, it can move and reset under the action of the elastic reset member without the need for the side brush adjustment assembly 3 to drive and adjust, so that the side brush assembly 2 works more intelligently and saves more energy.

[0049] It is understandable that when the sweeper is working normally, the side brush assembly 2 is in the second working position to be more retracted and closer to the sweeper body. When cleaning a narrow area and extending into a low area, the side brush assembly 2 can be extended to be in the first working position. Therefore, when the side brush assembly 2 is in the second working position, the side brush adjustment assembly 3 needs to be used to constrain the side brush assembly 2 so that the side brush assembly 2 will not be easily extended. When the side brush assembly 2 is in the first working position, the side brush adjustment assembly 3 can constrain the side brush assembly 2 or not constrain the side brush assembly 2.

[0050] Preferably, combined Figure 2 and Figure 3As shown, when the side brush adjustment assembly 3 is in the first working position, no retaining force is applied to the side brush assembly 2; wherein, when the side brush assembly 2 is in the first working position, the side brush assembly 2 can move from the first working position to the second working position under the action of an external force, and the elastic reset member is in an elastic force storage state. When the external force on the side brush assembly 2 is removed, the side brush assembly 2 can be reset from the second working position to the first working position under the action of the elastic reset force of the elastic reset member. For example, when the side brush assembly 2 extends out of the main body of the sweeper to perform cleaning work in the first working position, the side brush assembly 2 may collide with obstacles such as walls and table legs. Under the action of external obstacles, a force will be applied to the side brush assembly 2, causing the side brush assembly 2 to move toward the second working position to be retracted close to the main body of the sweeper, so that the side brush assembly 2 can better fit the edge of the obstacle for cleaning. On the one hand, the cleaning effect is better, and on the other hand, the body will not collide with the obstacle to cause the sweeper to get stuck. When the side brush assembly 2 has finished cleaning the obstacle area, the elastic reset member can automatically reset the side brush assembly 2 to the first working position and continue cleaning. There is no need for the side brush adjustment assembly 3 to adjust and move the side brush assembly 2, which is more energy-efficient and easier to operate.

[0051] For the side brush adjustment assembly 3, preferably, combined with Figure 3 and Figure 6 As shown, the side brush adjustment assembly 3 includes an adjustment driver 31 and a transmission rod 32, wherein the adjustment driver 31 is arranged on the substrate 1; the transmission member is connected to the adjustment driver 31, and the transmission member is in contact with the side brush assembly 2; wherein the adjustment driver 31 drives the transmission member to rotate, and under the cooperation of the transmission member and the side brush assembly 2, the side brush assembly 2 can be driven to rotate, so that the side brush assembly 2 can move from the first working position to the second working position. The adjustment driver 31 can be set as a driving motor, and the driving motor drives the transmission member to rotate, so that the transmission member can abut against the side brush assembly 2, thereby driving the side brush assembly 2 to rotate, so that the side brush assembly 2 can move from the first working position to the second working position.

[0052] More preferably, in combination Figure 3 and Figure 6As shown, the transmission member includes a transmission rod 32, which is generally arranged in a long strip shape to have two ends along the length direction, and one end of the transmission rod 32 along its length direction is connected to the adjustment driver 31; a matching portion 211 is provided on one side of the side brush assembly 2, and the other end of the transmission rod 32 along its length direction abuts against the matching portion 211, and the adjustment driver 31 drives the transmission rod 32 to rotate along a first direction, and under the cooperation of the transmission rod 32 and the matching portion 211, the side brush assembly 2 can be driven to rotate along a second direction, so that the side brush assembly 2 moves to the second working position, wherein the first direction and the second direction are opposite. Wherein, when the first direction is clockwise, the second direction is counterclockwise, and if the first direction is counterclockwise, the second direction is clockwise. When the side brush assembly 2 is in the second working position, the side brush assembly 2 can be closer to the side brush adjustment assembly 3, and occupy less space.

[0053] For the side brush assembly 2, combined Figures 3 to 6 As shown, the side brush assembly 2 includes a side brush mounting plate 21, a side brush structure 22 and a side brush driving structure 23. The side brush mounting plate 21 is rotatably disposed on the base plate 1. The matching portion 211 includes a protrusion 2111 disposed on one side of the side brush mounting plate 21. The front end of the transmission rod 32 along the first direction abuts against the protrusion 2111. When the transmission rod 32 rotates along the first direction, the protrusion 2111 can be pushed to rotate along the second direction, thereby driving the entire side brush mounting plate 21 to rotate along the second direction; the side brush structure 22 is rotatably disposed on the side brush mounting plate 21; the side brush driving structure 23 is disposed on the side brush mounting plate 21 and is drivingly connected to the side brush structure 22. The side brush driving structure 23 is used to drive the side brush structure 22 to rotate relative to the side brush mounting plate 21. The side brush structure 22 and the side brush driving structure 23 are respectively located at the two ends of the side brush mounting plate 21. When the side brush mechanism 100 is set on the sweeping machine body, the side brush driving structure 23 can be located on the inner side of the sweeping machine body. When the side brush assembly 2 is in the first working position, the side brush structure 22 can be better located on the outside of the sweeping machine body, thereby better extending out of the sweeping machine body.

[0054] Furthermore, if Figure 7As shown in the figure, the side brush driving structure 23 includes a side brush driver 231 and a plurality of transmission gears 232. The plurality of transmission gears 232 mesh with each other. The transmission gear 232 at the transmission start end of the plurality of transmission gears 232 is connected to the side brush driver 231, and the transmission gear 232 at the transmission end of the plurality of transmission gears 232 is connected to the side brush structure 22. The plurality of transmission gears 232 form a reducer so that the speed of the side brush structure 22 is not too fast when rotating for cleaning. The side brush driver 231 is arranged at one end of the side brush mounting plate 21 close to the adjustment driver 31, and the rotation axis of the side brush driver 231 is arranged in parallel with the rotation axis of the adjustment driver 31. The side brush driver 231 is close to the adjustment driver 31, so that the side brush mounting plate 21 has enough rotation space. The protrusion 2111 is located at one end close to the side brush driver 231, so that it can better cooperate with the transmission rod 32.

[0055] Preferably, the side brush mounting plate 21 is extended radially outward from the side brush driver 231, and the side brush mounting plate 21 is arranged in an arc shape protruding toward the first direction, so that the side brush mounting plate 21 is roughly arranged in a fan blade shape, so that the wind resistance is smaller during rotation, and the internal space of the side brush mounting plate 21 is larger.

[0056] Specifically, the side brush structure 22 includes a side brush mounting plate and bristles arranged on the side brush mounting plate. The side brush mounting plate is connected to a transmission gear 232 at the transmission end among multiple transmission gears 232, so that the multiple transmission gears 232 are driven to rotate through the side brush driver 231, so that the side brush mounting plate rotates, driving the bristles to rotate to clean the surface to be cleaned.

[0057] In one embodiment, in combination Figure 5 and Figure 8 As shown, the side brush mechanism 100 further includes a position detection structure 4 and a controller. The controller is electrically connected to the position detection structure 4 and the adjustment driver 31. The position detection structure 4 is used to detect the position of the transmission rod 32. The controller is used to control the adjustment driver 31 to work according to the detection result of the position detection structure 4. When the transmission rod 32 rotates from the first working position to the second working position under the drive of the adjustment driver 31, the position detection structure 4 detects the transmission rod 32, thereby transmitting the detection signal to the controller, and the controller controls the adjustment driver 31 to stop working, so that the transmission rod 32 is kept at the second working position.

[0058] Specifically, Figure 8As shown in the figure, the position detection structure 4 includes a first detector 41 and a second detector 42 arranged on the substrate 1, and a detection block 43 arranged on the transmission rod 32, and the first detector 41 and the second detector 42 are arranged at intervals along the circumference of the adjustment driver 31; when the detection block 43 is located in the detection area of ​​the first detector 41, the side brush assembly 2 is in the first working position, and when the detection block 43 is in the detection area of ​​the second detector 42, the side brush assembly 2 is in the second working position. When the transmission rod 32 moves to the second working position under the drive of the adjusting driver 31, the detection block 43 on the transmission rod 32 is just located in the detection area of ​​the second detector 42, so that the second detector 42 can transmit the detection signal to the controller, and the adjusting driver 31 can be controlled by the controller to stop working to keep the transmission rod 32 at the second working position; when the side brush structure 22 is to be rotated from the second working position to the first working position, the adjusting driver 31 can be controlled by the controller to rotate in the opposite direction to drive the transmission rod 32 to rotate in the second direction to move in the direction away from the protrusion 2111, so that the side brush assembly 2 is no longer subject to the push-up effect of the transmission rod 32, so that the side brush assembly 2 can be rotated from the second working position to the first working position under the action of the elastic recovery member.

[0059] Furthermore, the transmission rod 32 has a first transmission section and a second transmission section, and the first transmission section and the second transmission section are respectively located on both sides of the radial direction of the rotating shaft of the adjustment driver 31. The first transmission section abuts against the protrusion 2111 on the side brush mounting plate 21, and the detection block 43 is arranged on the second transmission section. The detection area of ​​the first detector 41 and the detection area of ​​the second detector 42 are both on the moving track surface of the detection block 43, so that the detection block 43 can better enter the detection area of ​​the first detector 41 and the detection area of ​​the second detector 42.

[0060] The base plate 1 is roughly in the shape of a plate, a first support column 11 is protruding from the base plate 1, a second support column 24 is provided on the side brush mounting plate 21 and / or the side brush driver 231, the first support column 11 is located on one side of the adjustment driver 31, the second support column 24 is located on one side of the side brush driver 231, and the two ends of the elastic reset member are respectively connected to the first support column 11 and the second support column 24, when the side brush assembly 2 is in the first working position, the elastic reset member is in a natural state, and when the side brush assembly 2 is in the second working position, the elastic reset member is in a stretched state. The elastic reset member can be set as a tension spring, an elastic rubber member, etc.

[0061] In addition, the side brush mechanism 100 also includes a limiting structure 5 provided on the substrate 1, and the limiting structure 5 includes a first limiting surface 51 and a second limiting surface 52 which are arranged at intervals along the circumference of the adjustment drive; when the transmission rod 32 is in the first working position, the front end surface of the transmission rod 32 along the second direction abuts against the first limiting surface 51 to limit the transmission rod 32 from continuing to rotate in the second direction; when the transmission rod 32 is in the second working position, the front end surface of the transmission rod 32 along the first direction abuts against the second limiting surface 52 to limit the transmission rod 32 from continuing to rotate in the first direction, which can better protect the transmission rod 32 and the side brush assembly 2 and avoid excessive rotation and extrusion.

[0062] The utility model also provides a sweeping machine, which includes the above-mentioned side brush mechanism 100. The side brush mechanism 100 can expand the cleaning range of the sweeping machine and can extend into narrow or low areas for cleaning, so that the cleaning function of the sweeping machine is more powerful and the cleaning effect is better.
