[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0030] like Figure 1 and Figure 2 As shown, the cleaning robot according to the embodiment of the present application includes a chassis 10 , a cleaning component 20 and a floating component 30 .

[0031] Specifically, a support seat 11 is provided on the chassis 10; the floating assembly 30 includes a first connecting rod 31 and an elastic group 32, there is at least one first connecting rod 31, and there is at least one elastic group 32. The first connecting rod 31 is hinged to the support seat 11 and the cleaning assembly 20 respectively, and the elastic group 32 connects the first connecting rod 31 and the chassis 10.

[0032] In detail, a support base 11 is provided on the chassis 10, and the support base 11 is used to be hinged with the first connecting rod 31. The first connecting rod 31 and the cleaning component 20 are hinged respectively, that is to say, the first connecting rod 31 and the support base 11 and the cleaning component 20 can respectively rotate relative to each other, which can ensure that when the cleaning component 20 encounters an obstacle, it can timely correct the angle relative to the chassis 10 so as to fit the ground as closely as possible. The elastic group 32 connects the first connecting rod 31 and the chassis 10, and can provide tension and support for the first connecting rod 31 to prevent the first connecting rod 31 from sagging completely due to gravity. When the cleaning component 20 needs to cross an obstacle, the elastic group 32 will be compressed, and the first connecting rod 31 will move toward the chassis 10 to lift the cleaning component 20. After the cleaning component 20 crosses the obstacle, the jacking force exerted on the elastic group 32 at least partially disappears, and the elastic group 32 is at least partially reset to make the first connecting rod 31 away from the chassis 10, thereby keeping the cleaning component 20 able to adaptably fit the ground condition at all times without overloading. The structure is simple, the stability is high, and the manufacturing cost is greatly reduced.

[0033] The number of the first connecting rods 31 can be set as needed. For example, the number of the first connecting rods 31 is one or more. When the number of the first connecting rods 31 is more than one, the number of the elastic groups 32 can be one or more.

[0034] When there are multiple elastic groups 32, the multiple elastic groups 32 can correspond one-to-one to the multiple first connecting rods 31, or can not correspond one-to-one. For example, there are three first connecting rods 31, and the three first connecting rods 31 are distributed in sequence along the length direction of the cleaning component 20, while there are two elastic groups 32, and the two elastic groups 32 are respectively connected to the first connecting rods 31 located on both sides.

[0035] For example, there are three first connecting rods 31 , which are spaced apart in sequence along the length direction of the cleaning assembly 20 , and there are four elastic groups 32 , with every two elastic groups 32 connected to a first connecting rod 31 on both sides.

[0036] For example, there are three first connecting rods 31 , which are spaced apart in sequence along the length direction of the cleaning assembly 20 , and there are six elastic groups 32 , each first connecting rod 31 corresponds to two elastic groups 32 , and every two elastic groups 32 are connected to the same first connecting rod 31 .

[0037] like Figure 2 As shown, according to the cleaning robot of the embodiment of the present application, the floating component 30 includes a first connecting rod 31 and an elastic group 32. The first connecting rod 31 is hinged to the support base 11 and the cleaning component 20 respectively. In this way, when the cleaning component 20 is on an uneven ground, the relative rotation angle with the first connecting rod 31 can change so as to rise and fall with the ground, thereby keeping the cleaning component 20 able to adaptively fit the ground condition at all times without overloading. The structure is simple and the stability is high. There is no need to add additional driving components to change the position of the cleaning component 20, which also greatly reduces the production cost.

[0038] like Figure 2 As shown, according to the cleaning robot of the embodiment of the present application, the first connecting rod 31 includes a first end and a second end opposite to each other, and the first end and the second end are respectively hinged to the support base 11 and the cleaning assembly 20, and the position where the first connecting rod 31 is connected to the elastic group 32 is located between the first end and the second end.

[0039] In detail, the first connecting rod 31 includes a first end and a second end relative to each other, and the first end and the second end are respectively hinged to the support seat 11 and the cleaning component 20. The position where the first connecting rod 31 is connected to the elastic group 32 is set between the first end and the second end. This can ensure that the tensile force of the elastic group 32 on the first connecting rod 31 can support the cleaning component 20 without increasing the length of the first connecting rod 31.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the elastic group 32 includes a spring 321, a sleeve 322 and a guide rod 323, the guide rod 323 can be extended into the sleeve 322, the spring 321 is sleeved outside the sleeve 322 and the guide rod 323, one of the sleeve 322 and the guide rod 323 is connected to the chassis 10, and the other is connected to the cleaning assembly 20.

[0041] That is to say, in order to ensure that the elastic group 32 can always maintain a relatively fixed moving trajectory when the cleaning component 20 is in various working conditions, so as to better play a stretching role on the first connecting rod 31, a sleeve 322 and a guide rod 323 are set to limit the spring 321, thereby preventing the spring 321 from getting stuck and twisting during the stretching or compression process. As the cleaning component 20 elastically rises and falls, the guide rod 323 gradually extends into the sleeve 322 or gradually extends out of the sleeve 322 relative to the sleeve 322, adaptively changing their positional relationship, so that the spring 321 can be compressed or stretched.

[0042] It is understandable that, on a normal relatively flat road surface, at least a portion of the guide rod 323 is inserted into the sleeve 322, and the distance between the end of the guide rod 323 close to the sleeve 322 and the inner top wall of the sleeve 322 should be sufficient to allow the guide rod 323 to extend when the spring 321 is compressed.

[0043] In some embodiments, the sleeve 322 and the chassis 10 are hinged.

[0044] As the cleaning component 20 fluctuates with the ground, the cleaning component 20 changes its relative angle with the chassis 10 while fitting as closely to the ground as possible. At this time, the angle between the first connecting rod 31 and the support seat 11 also changes, and the angle of the elastic group 32 relative to the vertical direction also changes relatively. At this time, in order to ensure that the spring 321 does not get stuck and to enable the spring 321 to release tension or pressure more easily in the appropriate direction, the sleeve 322 is hinged to the chassis 10, so that the sleeve 322 can adaptively change the relative angle between the sleeve 322 and the chassis 10 along with the spring 321.

[0045] like Figure 3As shown, in some embodiments, the guide rod 323 is hinged to the first connecting rod 31. Similarly, when the cleaning assembly 20 fluctuates with the ground, the cleaning assembly 20 changes its relative angle with the chassis 10 while being in close contact with the ground as much as possible. At this time, the angle between the first connecting rod 31 and the support seat 11 also changes, and the angle of the elastic group 32 relative to the vertical direction also changes relatively. At this time, in order to ensure that the spring 321 will not get stuck and to make it easier for the spring 321 to release tension or pressure in the appropriate direction, the guide rod 323 is hinged to the first connecting rod 31, so that the guide rod 323 can adaptively change the relative angle between the guide rod 323 and the first connecting rod 31 with the spring 321.

[0046] In some embodiments, a first limiter is disposed on the sleeve 322 , a second limiter is disposed on the guide rod 323 , and the spring 321 abuts against the first limiter and the second limiter, respectively.

[0047] In detail, a first limit piece is provided on the sleeve 322, and a second limit piece is provided on the guide rod 323. The spring 321 is respectively stopped by the first limit piece and the second limit piece, so as to limit the spring 321 and prevent the spring 321 from getting stuck. The first limit piece and the sleeve 322 are integrally formed, and the second limit piece and the guide rod 323 are integrally formed.

[0048] In some embodiments, the inner diameter of the sleeve 322 is greater than or equal to twice the diameter of the guide rod 323 .

[0049] In detail, since the guide rod 323 and the sleeve 322 will be misaligned with the rotation of the first connecting rod 31, in order to ensure that the guide rod 323 can always be smoothly extended into or withdrawn from the sleeve 322, the inner diameter of the sleeve 322 is set larger than the diameter of the guide rod 323, which can avoid jamming between the guide rod 323 and the sleeve 322.

[0050] For example, the inner diameter of the sleeve 322 is D, the diameter of the guide rod 323 is d, and D can be 2d, 2.5d, 3d, 3.5d, 4d, 4.5d, 5d, etc.

[0051] like Figure 1 and Figure 2 As shown, the cleaning robot according to the embodiment of the present application further includes a second connecting rod 40, the two ends of which are respectively hinged to the support base 11 and the cleaning component 20, and the position where the second connecting rod 40 is hinged to the cleaning component 20 is higher than the position where the first connecting rod 31 is hinged to the cleaning component 20.

[0052] In detail, the two ends of the second connecting rod 40 are hinged to the support seat 11 and the cleaning component 20 respectively. In this way, the second connecting rod 40 can be used to assist the first connecting rod 31 in supporting the cleaning component 20. The position where the second connecting rod 40 is hinged to the cleaning component 20 is higher than the position where the cleaning component 20 is hinged. Since the cleaning component 20 is larger than the connecting rods (the first connecting rod 31 and the second connecting rod 40) and the cleaning component 20 is not fixed, the second connecting rod 40 and the first connecting rod 31 are hinged at a position different from the height direction of the cleaning component 20, which can increase the stability of the cleaning component 20.

[0053] like Figure 2 As shown, in some embodiments, there are two first connecting rods 31 , which are spaced apart along the length direction of the cleaning assembly 20 , and there are two second connecting rods 40 , which are disposed between the two first connecting rods 31 .

[0054] In detail, there are two first connecting rods 31, and the two first connecting rods 31 are spaced apart along the length direction of the cleaning component 20, so that the force on the cleaning component 20 is more balanced and more stable. There are two second connecting rods 40, and the two second connecting rods 40 are arranged between the two first connecting rods 31. This makes it convenient to set the distance between the two second connecting rods 40, so as to better apply force to the cleaning component 20 and make the cleaning component 20 more stable when allowed on uneven ground.

[0055] like Figure 2 As shown, in some embodiments, the distance between the ends of the two second connecting rods 40 connected to the cleaning assembly 20 is smaller than the distance between the ends of the two second connecting rods 40 connected to the support base 11 .

[0056] Specifically, the distance between the ends of the two connecting rods connected to the cleaning assembly 20 is smaller than the distance between the ends of the two second connecting rods 40 connected to the support seat 11, which enables the cleaning assembly 20 to be more flexible when adjusted with the ground, and to more adaptably fit the ground to avoid overload.

[0057] like Figure 2 As shown, according to the cleaning robot of the embodiment of the present application, the first connecting rod 31 is configured in an arc shape and protrudes in a direction away from the chassis 10 .

[0058] According to the cleaning robot of the embodiment of the present application, the first connecting rod 31 is configured to be arc-shaped and protrudes in a direction away from the chassis 10, which can facilitate the installation of the elastic group 32 and allow the natural length of the elastic group 32 to meet the requirements of tension or compression.

[0059] In a specific embodiment, the cross section of the second connecting rod 40 is circular, the cross section of the first connecting rod 31 is rectangular, that is, square or rectangular, and the width of the cross section of the first connecting rod 31 is greater than the diameter of the second connecting rod 40. The first connecting rod 31 is hinged to the cleaning assembly 20 by bolts, and the first connecting rod 31 is hinged to the support seat 11 by bolts.

[0060] The second connecting rod 40 is hinged to the cleaning assembly 20 through bolts, and the second connecting rod 40 is hinged to the support seat 11 through bolts.
