DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present disclosure.

[0032] Figure 9 A partial enlarged view of the brush assembly in area A is shown. Figure 8 A sectional view of the brush assembly in direction C-C is shown. Figure 10 A partial enlarged view of the brush assembly in area A is shown. Figure 9 A partial enlarged view of the brush assembly in area D is shown. As Figures 1 to 10 The brush assembly 10 includes a fixing member 100, an elastic member 200, and a brush 300.

[0033] The fixing member 100 can be connected with a driving source and rotate under the driving of the driving source. Exemplarily, the fixing member 100 is fixedly connected with the driving source, so as to transmit the rotating force of the driving source to the elastic member 200. Exemplarily, the driving source is a motor, a rotary electric cylinder, etc.

[0034] The elastic member 200 includes two elastic portions 210 arranged oppositely, and a first connecting portion 220 connecting the two elastic portions 210, and the first connecting portion 220 is connected with the fixing member 100. Exemplarily, the elastic member 200 has a deformation characteristic, can be deformed under the action of an external force F, and can restore the original shape after the external force F is removed. For example, the material of the elastic member 200 can be PA66+GF30, PP+TD20, etc. PA66+GF30 is a kind of nylon material, in which PA66 is the base resin, GF30 indicates that 30% of glass fiber is added, and PA66+GF30 has high strength, high rigidity and special thermal stability. PP+TD20 refers to polypropylene composite polyethylene terephthalate and plasticizer, in which TD can simultaneously play the roles of reinforcement and plasticization, can improve the strength, toughness and heat resistance of PP, and increase the application range and service life of PP+TD20.

[0035] As Figure 5As shown, the vertical distance between the outer sides of the two elastic parts 210 is a first distance d1 without the external force F. As shown, Figure 6 As shown, the two elastic parts 210 are close to each other under the external force F, so that the vertical distance between the two elastic parts 210 is a second distance d2. As shown, Figure 5 As shown, the vertical distance between the two elastic parts 210 returns to the first distance d1 after the external force F is removed. The first distance d1 is greater than the second distance d2. Exemplarily, the external force F can be the force generated by the user's finger pressing the elastic part 210, or the force generated by the clamping device, pressing device, etc. pressing the elastic part 210.

[0036] The brush 300 has a mounting hole 301. The diameter d6 of the mounting hole is less than or equal to the first distance d1, and greater than the second distance d2. The two elastic parts 210 pass through and extend out of the mounting hole 301.

[0037] Since the diameter d6 of the mounting hole is less than or equal to the first distance d1, the brush 300 can be firmly sleeved on the two elastic parts 210 and be tensioned by the elastic part 210. In the case of replacing the brush 300, only need to press the two elastic parts 210, so that the vertical distance between the two elastic parts 210 is the second distance d2, so that the brush 300 is separated from the two elastic parts 210, and then another brush 300 is sleeved on the two elastic parts 210. The whole process of replacing the brush 300 is simple, and the brush 300 is easy to disassemble and assemble.

[0038] In some embodiments, the elastic part 210 includes a deformation part 211, a pressing part 212, and an abutting part 213. The deformation part 211 is connected with the first connecting part 220. The pressing part 212 is connected with the end of the deformation part 211 away from the first connecting part 220. The abutting part 213 is connected with the pressing part 212. The outer side of the abutting part 213 of each of the two elastic parts 210 in the first direction X is a third distance d3 greater than the outer side of the deformation part 211 of each of the two elastic parts 210 in the first direction X. The first direction X is the direction from one elastic part 210 to the other elastic part 210. The brush 300 is sleeved on the outer sides of the two deformation parts 211, the pressing part 212 and the abutting part 213 extend out of the mounting hole 301, and the abutting part 213 abuts against the end surface of the brush 300 away from the first connecting part 220. Exemplarily, as shown, Figure 5 As shown, the end surface of the brush 300 away from the first connecting part 220 is the lower end surface of the brush 300.

[0039] Exemplarily, the deformation part 211 has a deformation characteristic, which can be deformed under the external force F and can return to the original shape after the external force F is removed. Exemplarily, the material of the deformation part 211 can be PA66+GF30, PP+TD20, etc.

[0040] By setting the abutting portion 213 to abut against the end surface of the edge brush 300 away from the first connecting portion 220, the edge brush 300 can be prevented from falling off the deformation portion 211, and the firmness and reliability of the installation of the edge brush 300 are improved.

[0041] In some embodiments, as shown in Figure 3 and Figure 7 , the mounting hole 301 comprises a cylindrical hole. The elastic member 200 further comprises at least two oppositely arranged cooperating portions 230, the at least two cooperating portions 230 being symmetrically arranged relative to the two elastic portions 210, and the edge brush 300 being further sleeved on the outer side surface of the cooperating portion 230.

[0042] Specifically, the outer side surface of the cooperating portion 230 comprises a circular arc surface 231, which is adapted to the mounting hole 301, so as to limit the edge brush 300 in the radial direction by the circular arc surface 231, prevent the edge brush from shaking in the radial direction, and further improve the firmness and reliability of the installation of the edge brush 300.

[0043] For example, the radius of the circular arc surface 231 is equal to the radius of the mounting hole 301, so that the circular arc surface 231 is in close contact with the inner wall of the mounting hole 301.

[0044] In some embodiments, as shown in Figure 6 and Figure 10 , the fixing member 100 comprises a first annular portion 110. The first annular portion 110 is connectable to the driving source. The first annular portion 110 is sleeved on the elastic member 200, and has a mounting space between the outer side surface of the elastic portion 210. The inner side surface of the first annular portion 110 has at least one boss 111.

[0045] As shown in Figure 4 , Figure 6 and Figure 10 , the edge brush 300 comprises a second annular portion 310. The second annular portion 310 has the mounting hole 301, and the second annular portion 310 extends into the mounting space. The outer side surface of the second annular portion 310 has at least one groove 311, and the boss 111 extends into the groove 311, so as to limit the rotation of the edge brush 300 relative to the fixing member 100 along the circumferential direction of the first annular portion 110, and further improve the firmness and reliability of the installation of the edge brush 300.

[0046] In some embodiments, as shown in Figure 6 , the fixing member 100 further comprises a second connecting portion 120. The second connecting portion 120 is connected to one end of the first annular portion 110 close to the first end surface of the first annular portion 110, and is connectable to the driving source. For example, as shown in Figure 6As shown, the first end face of the first annular portion 110 is an upper end face of the first annular portion 110. The boss 111 comprises a transmission portion 1111 and a guide portion 1112 connected to each other, the guide portion 1112 extends to an end of the inner side face of the first annular portion 110 close to the second end face of the first annular portion 110, and the size of the guide portion 1112 in the circumferential direction of the first annular portion 110 gradually decreases in the direction from the first end face of the first annular portion 110 to the second end face of the first annular portion 110, and the size of the transmission portion 1111 in the circumferential direction of the first annular portion 110 is greater than or equal to the maximum size of the guide portion 1112 in the circumferential direction of the first annular portion 110, so that the guide portion 1112 enters the groove 311 first, and then the transmission portion 1111 enters the groove 311, facilitating blind assembly of the edge brush 300. Exemplarily, as shown in FIG. 3, the transmission portion 1111 is a flat surface, and the guide portion 1112 is a tapered surface. Figure 6 As shown, the second end face of the first annular portion 110 is a lower end face of the first annular portion 110, and the direction from the first end face of the first annular portion 110 to the second end face of the first annular portion 110 is a vertically downward direction.

[0047] In some embodiments, the edge brush 300 further comprises a brush portion 320.

[0048] The brush portion 320 is arranged around an end of the second annular portion 310 close to the first end face of the second annular portion 310. The brush portion 320 is configured to be in contact with the surface to be cleaned to clean the surface to be cleaned. The end of the second annular portion 310 close to the second end face of the second annular portion 310 extends into the mounting space. The groove 311 comprises a transmission groove 3111 and a guide groove 3112 connected to each other. The transmission portion 1111 extends into the transmission groove 3111, and the guide groove 3112 extends to an end of the second annular portion 310 close to the second end face of the second annular portion 310, and the size of the guide groove 3112 in the circumferential direction of the second annular portion 310 gradually increases in the direction from the first end face of the second annular portion 310 to the second end face of the second annular portion 310, and the size of the transmission groove 3111 in the circumferential direction of the second annular portion 310 is less than or equal to the minimum size of the guide groove 3112 in the circumferential direction of the second annular portion 310, so that the boss 111 enters the guide groove 3112 first, and then enters the transmission groove 3111, further improving the convenience of blind assembly of the edge brush 300.

[0049] In some embodiments, the number of bosses 111 is a plurality, and the plurality of bosses 111 are uniformly distributed along the circumferential direction of the first annular portion 110. The number of grooves 311 is equal to the number of bosses 111, and the plurality of grooves 311 are uniformly distributed along the circumferential direction of the second annular portion 310, so that when the edge brush 300 is installed, only a small angle of rotation of the edge brush 300 is needed to align the boss 111 and the groove 311, further improving the convenience of blind assembly of the edge brush 300.

[0050] In some embodiments, the side brush assembly 10 further comprises at least one spring plunger 400. The spring plunger 400 is connected with the fixing member 100. Exemplarily, the spring plunger 400 is a standard part, also known as a ball head plunger or a positioning column.

[0051] When the side brush 300 is installed on the elastic part 210, the spring plunger 400 abuts against the side brush 300. Under the action of the external force F, the two elastic parts 210 are close to each other, so that the vertical distance between the two elastic parts 210 is the second distance d2, and the spring plunger 400 extends towards the side brush 300 to pop out the side brush 300, facilitating the disassembly of the side brush 300.

[0052] In some embodiments, the first annular part 110 has at least one stepped hole 112 configured to install the spring plunger 400. The stepped hole 112 comprises a first shaft hole 1121 and a second shaft hole 1122 in communication with each other, and the second shaft hole 1122 extends to the second end surface of the first annular part 110, and the diameter of the first shaft hole 1121 is greater than that of the second shaft hole 1122 to form a stepped surface 1123 at the connecting position of the first shaft hole 1121 and the second shaft hole 1122.

[0053] The spring plunger 400 comprises a fixed part 410 and an extension part 420. The fixed part 410 is arranged in the first shaft hole 1121 and abuts against the stepped surface 1123. The extension part 420 is connected with the fixed part 410 and extends into the second shaft hole 1122, and the extension part 420 is configured to extend and retract along the axial direction of the second shaft hole 1122. Exemplarily, the outer side surface of the fixed part 410 can be provided with external threads, and the inner wall of the first shaft hole 1121 can be provided with internal threads, so as to realize the screw connection of the fixed part 410 and the first annular part 110, facilitating the disassembly of the spring plunger 400.

[0054] When the side brush 300 is installed on the elastic part 210, the end of the extension part 420 away from the fixed part 410 abuts against the side brush 300. Under the action of the external force F, the two elastic parts 210 are close to each other, so that the vertical distance between the two elastic parts 210 is the second distance d2, and the extension part 420 extends towards the side brush 300 to pop out the side brush 300, facilitating the disassembly of the side brush 300.

[0055] In some embodiments, in the direction indicated by the deformation part 211 to the pressing part 212, the distance between the outer side surfaces of the pressing parts 212 of the two elastic parts 210 gradually decreases. At the end of the pressing part 212 away from the deformation part 211, the distance between the outer side surfaces of the pressing parts 212 of the two elastic parts 210 is a fifth distance d5, and the fifth distance d5 is smaller than the diameter d6 of the mounting hole, further improving the convenience of blind installation of the side brush 300.

[0056] In some embodiments, the outer side of the pressing part 212 has a recess 2121 configured to accommodate a force applying object. Exemplarily, the force applying object can be a finger of a user, or a clamping device, a pressing device, etc.

[0057] In some embodiments, the inner side of the elastic part 210 has a reinforcing rib 214 extending from the deformation part 211 to the pressing part 212, which improves the strength of the elastic part 210 and reduces the probability of breakage of the elastic part 210.

[0058] The present disclosure also provides a cleaning robot. Figure 11 As shown in the structural schematic diagram of the cleaning robot provided by an embodiment of the present disclosure, the cleaning robot 1 comprises a side brush assembly 10, a main body 20 and a driving source 30. Figure 11 As shown, the cleaning robot 1 comprises a side brush assembly 10, a main body 20 and a driving source 30.

[0059] The driving source 30 is connected with the main body 20. Exemplarily, the driving source 30 can be a motor, a rotary cylinder, etc., as long as it can provide a rotating force. The side brush assembly 10 is connected with the driving source 30 and rotates under the driving of the driving source 30. Exemplarily, the number of the driving sources 30 can be multiple, and the number of the side brush assemblies 10 can be multiple, and the multiple driving sources 30 and the multiple side brush assemblies 10 can correspond one by one. Figure 11 As shown, two driving sources 30 and two side brush assemblies 10 are shown. In actual application, the cleaning robot 1 can only comprise one driving source 30 and one side brush assembly 10.

[0060] Since the cleaning robot 1 comprises the side brush assembly 10 in the above-mentioned embodiments, the cleaning robot 1 comprises all the technical features and technical effects of the side brush assembly 10, which will not be described here again.

[0061] In the embodiments of the present disclosure, if the form of connection is not explicitly limited, the form of connection can be a detachable connection form such as a bolt and nut, a screw, a buckle, magnetic attraction, etc. In some connections, if there is no special requirement for the form of non-detachable cooperation, non-detachable connection can be achieved by welding, bonding, etc.
