[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] This embodiment of the utility model provides a cleaning brush 100, which is detachably mounted on the robot body 200 of a cleaning robot, specifically detachably mounted on the bottom of the robot body 200. (See reference...) Figure 1 The cleaning brush 100 includes a brush body 110 and bristles 120. The brush body 110 includes a strip-shaped main body 111 and at least two L-shaped clips 112 extending from a first side of the strip-shaped main body 111. The L-shaped clips 112 cooperate with the strip-shaped main body 111 to form a snap-fit ​​groove 113, which is used for detachable connection with the bottom plate 211 of the robot body 200. The bristles 120 are disposed on a second side of the strip-shaped main body 111. The first and second sides of the strip-shaped main body 111 are two oppositely arranged sides.

[0031] As an example, refer to Figure 2 and Figure 3 The cleaning brush 100 can be installed at the bottom of the robot body 200. A strip-shaped mounting groove 210 is provided at the bottom of the robot body 200, and a snap-fit ​​hole 212 is provided on the strip-shaped mounting groove 210. The assembly process is as follows: Pass the L-shaped snap-fit ​​112 through the snap-fit ​​hole 212 of the robot body 200, and then move the cleaning brush 100 along the first direction. When the side of the snap-fit ​​groove 113 abuts against the bottom plate 211 of the groove, the cleaning brush 100 and the robot body 200 can be detachably connected. When it is necessary to disassemble the cleaning brush 100, push the cleaning brush 100 in the opposite direction of the first direction to unlock the connection between the cleaning brush 100 and the robot body 200. Using the above structure, the cleaning brush 100 and the robot body 200 can be detachably connected, reducing the operational difficulty of connecting the two, improving connection efficiency, and facilitating the cleaning of the cleaning brush 100.

[0032] In one embodiment, reference is made to Figure 1 At least two L-shaped buckles 112 are spaced apart on the strip-shaped body 111.

[0033] As an example, the L-shaped buckle 112 is used to connect to the buckle hole 212 on the strip mounting groove 210, realizing a detachable connection between the cleaning brush 100 and the robot body 200. The cleaning brush 100 is long and narrow, such as rectangular. The length of the strip body 111 is much greater than the length of the L-shaped buckle 112. If only one L-shaped buckle 112 connects the cleaning brush 100 to the robot body 200, its stability is insufficient. After prolonged use, the cleaning brush 100 will wobble from side to side, affecting its cleaning efficiency. Therefore, at least two L-shaped buckles 112 are provided at intervals on the strip body 111. By using at least two L-shaped buckles 112 to detachably connect to the robot body 200, the number of connection points is increased, thereby making the connection between the cleaning brush 100 and the robot body 200 more secure.

[0034] In one embodiment, reference is made to Figure 1 The first side of the strip-shaped main body 111 is also provided with a positioning bead 114, which is used to be assembled in the positioning groove 213 provided on the bottom plate 211.

[0035] As an example, the positioning ball 114 is used to control the force at which the L-shaped latch 112 disengages, preventing the cleaning brush 100 from falling off the robot body 200 during operation. During installation, a "pop" sound indicates that the positioning ball 114 has fallen into the positioning groove 213, achieving a detachable connection between the cleaning brush 100 and the robot body 200. To remove the cleaning brush 100 from the robot body 200, it is necessary to push the cleaning brush 100 in the opposite direction of the first direction, and the pushing force must be greater than the resistance of the positioning ball 114 to push the positioning ball 114 out of the positioning groove 213, thus removing the cleaning brush 100 from the robot body 200.

[0036] In one embodiment, reference is made to Figure 1 One end of the strip-shaped main body 111 forms a right-angle structure 115, and the other end of the strip-shaped main body 111 forms an L-shaped limiting structure 116. The extension direction of the L-shaped limiting structure 116 is opposite to the extension direction of the L-shaped buckle 112.

[0037] As an example, one end of the strip-shaped body 111 forms a right-angle structure 115, and the other end of the strip-shaped body 111 forms an L-shaped limiting structure 116. The extending direction of the L-shaped limiting structure 116 is opposite to the extending direction of the L-shaped buckle 112. In the robot body 200 to be installed, the first limiting protrusion 214 and the second limiting protrusion 215 at both ends of the groove bottom plate 211, where the height of the first limiting protrusion 214 is greater than the height of the second limiting protrusion 215, when the cleaning brush 100 is assembled on the robot body... When the body 200 is in place, the right-angle structure 115 abuts against the side of the taller first limiting protrusion 214, and the L-shaped limiting structure 116 abuts against the bottom of the taller and smaller second limiting protrusion 215, so that the sum of the heights of the L-shaped limiting structure 116 and the second limiting protrusion 215 is the same as the height of the first limiting protrusion 214, so as to ensure the overall aesthetics of the cleaning brush 100 and the robot body 200, and also to facilitate the cleaning brush 100 to be snapped and installed from the second limiting protrusion 215 to the first limiting protrusion 214.

[0038] This utility model provides a cleaning robot, as shown in the reference. Figure 2 and Figure 3 The system includes a robot body 200 and a cleaning brush 100 as described in the above embodiments. The robot body 200 is provided with a strip-shaped mounting groove 210, which includes a groove bottom plate 211. The groove bottom plate 211 is provided with at least two snap-fit ​​holes 212. A strip-shaped body 111 is assembled in the strip-shaped mounting groove 210, and an L-shaped snap-fit ​​112 passes through the snap-fit ​​hole 212, so that the snap-fit ​​groove 113 formed by the L-shaped snap-fit ​​112 and the strip body 111 is detachably connected to the groove bottom plate 211.

[0039] As an example, the cleaning robot includes a robot body 200 and a cleaning brush 100 mounted on the bottom of the robot body 200. The robot body 200 has a strip-shaped mounting groove 210. When the cleaning robot is used for cleaning the ground, the strip-shaped mounting groove 210 can be provided on the bottom of the robot body 200, and at least two snap-fit ​​holes 212 are provided on the strip-shaped mounting groove 210 to achieve a detachable connection with the strip-shaped body 111 on the cleaning brush 100. The assembly process of the cleaning brush 100 and the robot body 200 is as follows: pass the L-shaped snap-fit ​​112 through the snap-fit ​​hole 212, and then move the cleaning brush 100 along the first direction. When the side of the snap-fit ​​groove 113 abuts against the bottom plate 211 of the groove, the cleaning brush 100 can be detachably connected to the robot body 200. When it is necessary to disassemble the cleaning brush 100, push the cleaning brush 100 in the opposite direction of the first direction to unlock the connection between the cleaning brush 100 and the robot body 200. The above structure enables a detachable connection between the cleaning brush 100 and the robot body 200, reducing the difficulty of connecting the two, improving the connection efficiency, and facilitating the cleaning of the cleaning brush 100.

[0040] In one embodiment, reference is made to Figure 2 At least two buckle holes 212 are spaced apart on the bottom plate 211 of the groove, and each L-shaped buckle 112 corresponds to one buckle hole 212.

[0041] As an example, the bottom plate 211 is provided with at least two buckle holes 212 spaced apart, and the strip body 111 is provided with at least two L-shaped buckles 112 spaced apart. Each L-shaped buckle 112 corresponds to a buckle hole 212 in a one-to-one correspondence. With this structure, the connection points between the cleaning brush 100 and the robot body 200 are increased, making the connection between the cleaning brush 100 and the robot body 200 more secure.

[0042] In one embodiment, reference is made to Figure 2 The bottom plate 211 is also provided with a positioning groove 213, and the strip body 111 is also provided with a positioning ball 114, which is assembled on the positioning groove 213.

[0043] As an example, the positioning groove 213 is used to assemble the positioning ball 114. After successful assembly, the positioning ball 114 is used to control the force of the L-shaped buckle 112 to disengage, making the connection between the cleaning brush 100 and the robot body 200 more secure and preventing the cleaning brush 100 from falling off the robot body 200.

[0044] In one embodiment, reference is made to Figure 3 The strip mounting groove 210 also includes a first limiting protrusion 214 and a second limiting protrusion 215 disposed at both ends of the groove bottom plate 211. The height of the first limiting protrusion 214 is greater than the height of the second limiting protrusion 215. One end of the strip body 111 forms a right-angle structure 115, and the other end of the strip body 111 forms an L-shaped limiting structure 116. The extension direction of the L-shaped limiting structure 116 is opposite to the extension direction of the L-shaped buckle 112. The right-angle structure 115 abuts against the side of the first limiting protrusion 214, and the L-shaped limiting structure 116 abuts against the bottom surface of the second limiting protrusion 215.

[0045] As an example, the strip mounting groove 210 also includes a first limiting protrusion 214 and a second limiting protrusion 215 disposed at both ends of the groove bottom plate 211. The height of the first limiting protrusion 214 is greater than the height of the second limiting protrusion 215, that is, the bottom surface of the first limiting protrusion 214 is lower than the bottom surface of the second limiting protrusion 215. One end of the strip body 111 forms a right-angle structure 115, and the other end of the strip body 111 forms an L-shaped limiting structure 116. When the L-shaped buckle 112 of the cleaning brush 100 passes through the buckle hole 212 of the robot body 200 and is snapped into place, the right-angle structure 115 of the cleaning brush 100 abuts against the side of the first limiting protrusion 214, specifically matching the right-angle structure formed by the groove bottom plate 211 and the first limiting protrusion 214; correspondingly, the L-shaped limiting structure 116 of the cleaning brush 100 abuts against the bottom surface of the second limiting protrusion 215. Understandably, the sum of the heights of the L-shaped limiting structure 116 and the second limiting protrusion 215 is the same as the height of the first limiting protrusion 214, so as to ensure the overall aesthetics of the combination of the cleaning brush 100 and the robot body 200, and also to facilitate the snap-fit ​​installation of the cleaning brush 100 from the second limiting protrusion 215 to the first limiting protrusion 214.

[0046] In one embodiment, the bottom of the robot body 200 is also provided with an indicator arrow 216, the direction of which is the same as the extension direction of the strip mounting groove 210.

[0047] As an example, the bottom of the robot body 200 may also be provided with an indicator arrow 216, which is used to indicate the direction of installation of the cleaning brush 100. During assembly, when the extension direction of the L-shaped buckle 112 is consistent with the direction indicated by the indicator arrow 216, the cleaning brush 100 is moved to achieve a detachable connection between the cleaning brush 100 and the robot body 200. The design of the indicator arrow 216 makes it easy for users to clearly understand the disassembly and installation direction, which helps to improve the efficiency of disassembling and installing the cleaning brush 100.

[0048] In one embodiment, reference is made to Figure 2 The robot body 200 is the cleaning vehicle body, and the cleaning brush 100 is detachably mounted on the bottom of the cleaning vehicle body along the left and right direction of the vehicle.

[0049] As an example, the robot body 200 is the cleaning vehicle body. The cleaning vehicle body generally travels in the front-to-back direction of the vehicle. The cleaning brush 100 is detachably mounted on the bottom of the cleaning vehicle body in the left-to-right direction of the vehicle. This maximizes the contact area between the cleaning brush 100 and the ground when the cleaning vehicle body moves in the front-to-back direction of the vehicle, which helps to increase the cleaning area of ​​the cleaning brush 100 and thus ensure its cleaning efficiency.

[0050] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
