[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions 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. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In order to reduce the labor intensity and cost of lawn maintenance, automatic walking equipment for cutting and mowing lawns, such as lawn mowers, have been developed.

[0039] In currently common lawn mowers, the blade disc used for cutting is often set on the chassis of the lawn mower. However, grass clippings generated during lawn mowing will splash onto the chassis of the lawn mower and accumulate in the gap between the blade disc and the chassis, causing the weight of the lawn mower to increase and affecting the rotation of the blade disc, thereby reducing the mowing efficiency. It is also not easy to clean, resulting in a poor user experience.

[0040] Based on this, the present application provides an automatic walking device 1, which aims to efficiently and intelligently remove grass clippings or other foreign matter splashed onto the chassis 11, avoiding the accumulation of grass clippings on the chassis 11 that increases the weight of the blade 311 or other components in the device, thereby affecting the mowing efficiency.

[0041] See also Figures 1 to 4 The automatic walking device 1 provided in the present application can be used to walk in a designated area and cut a target object in the designated area. The designated area is, for example, a lawn, and the target object is, for example, weeds on the lawn. The automatic walking device 1 specifically includes a main body 10, a moving module 20, a cutting module 30 and an air flotation module 40. The following is a specific description of each component in the automatic walking device 1.

[0042] Specifically, in the automatic walking device 1, the moving module 20 is used to drive the main body 10 to move, and the main body 10 is provided with a chassis 11, and the cutting module 30 is provided corresponding to the chassis 11, and can move relative to the chassis 11 to perform a cutting action, thereby cutting the target object. More specifically, the chassis 11 is provided at the bottom of the automatic walking device 1, and when the automatic walking device 1 walks on a preset ground to perform corresponding work, the chassis 11 is located on a side close to the preset ground, and correspondingly, the cutting module 30 is opposite to the chassis 11 and is provided on a side of the chassis 11 close to the preset ground, and the cutting module 30 can move relative to the chassis 11 to cut the weeds on the preset ground.

[0043] Specifically, the chassis 11 forms an interlayer chamber 12 having an air flotation hole 113, the opening direction of the air flotation hole 113 is opposite to the cutting module 30, and the air flotation module 40 is arranged on the chassis 11, wherein the air flotation module 40 is used to introduce gas into the interlayer chamber 12 to spray airflow toward the cutting module 30 through the air flotation hole 113 of the interlayer chamber 12.

[0044] It should be understood that the flotation module 40 is used to introduce gas into the interlayer chamber 12. The gas introduced into the interlayer chamber 12 will form an airflow that is ejected toward the cutting module 30 through the flotation hole 113, thereby blowing the cutting module 30 through the ejected airflow to avoid the cutting module 30 being blocked by grass, and can efficiently and intelligently blow away grass clippings or other foreign matter splashed onto the chassis 11, so as to achieve pollution-free, efficient and convenient cleaning of the chassis 11.

[0045] Furthermore, the time for the air flotation module 40 to pass gas into the interlayer chamber 12 can be adjusted. For example, gas can be passed into the interlayer chamber 12 to form an airflow to clean the cutting module 30 when the cutting module 30 stops performing the cutting action. Alternatively, the air flotation module 40 can pass gas into the interlayer chamber 12 to form a clean airflow blowing toward the cutting module 30 while the cutting module 30 is performing the cutting action, so as to form an air flotation barrier on the side of the chassis 11 close to the cutting module 30, thereby effectively preventing foreign matter generated when the cutting module 30 performs the cutting action from splashing onto the chassis 11.

[0046] Furthermore, the rate at which the air flotation module 40 introduces gas into the interlayer chamber 12 can also be adjusted. It should be understood that by adjusting the rate at which the air flotation module 40 introduces gas, the intensity of the airflow ejected from the air flotation hole 113 can be adjusted to achieve the required cleaning effect.

[0047] In an optional embodiment, the cutting module 30 at least includes a cutting assembly 31 and a cutting drive assembly 32, wherein the cutting drive assembly 32 is used to drive the cutting assembly 31 to rotate so that the cutting assembly 31 can cut the target object. The cutting assembly 31 includes a cutter disc 311 and a cutting blade 312 for cutting the target object, wherein the cutter disc 311 is arranged at the bottom of the body 10 and is connected to the output shaft of the cutting drive assembly 32, and the cutting blade 312 is installed on the cutter disc 311, so that the cutting drive assembly 32 can drive the cutter disc 311 and the cutting blade 312 to rotate through the output shaft to improve the cutting efficiency and ensure the neat cutting of the lawn. The cutting drive assembly 32 can be, but is not limited to, a driving motor, and the cutter disc 311 is connected to the output shaft of the driving motor.

[0048] It should be noted that when the cutting component 31 cuts the target object, some foreign matter will splash to the top of the cutting component 31, especially the area near the top of the blade 311 near the output shaft, which will easily cause the peripheral side of the output shaft to be blocked by foreign matter (such as grass). In the present application, gas is introduced into the interlayer chamber 12 by the air flotation module 40 to form a clean airflow blowing toward the cutting module 30, which can prevent the cutting module 30 from being blocked by foreign matter.

[0049] In an optional embodiment, the automatic walking device 1 further includes a controller, which is used to control the action of the automatic walking device 1. Specifically, the controller is connected to the air flotation module 40 and the cutting drive assembly 32, and can be used to control the cutting drive assembly 32 to drive the cutting assembly 31 to rotate to cut the target object, and can also be used to control the air flotation module 40 to pass gas into the sandwich chamber 12, for example, to adjust the time and rate of the air flotation module passing gas into the sandwich chamber 12.

[0050] The controller is used to provide computing and control capabilities to support the operation of the entire computer device. For example, the controller can be a central processing unit (CPU), and the controller can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. Among them, the general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0051] In an optional embodiment, the self-propelled robot further includes a rotation speed regulator, which is electrically connected to the cutting drive assembly 32 and is used to adjust the rotation speed of the cutting assembly 31 .

[0052] like Figure 2 As shown, in an optional embodiment, the chassis 11 includes a substrate 111 and an air flotation plate 112 arranged on the side of the substrate 111 close to the cutting module 30, the substrate 111 and the air flotation plate 112 cooperate to form an interlayer chamber 12, and the air flotation hole 113 is opened in the air flotation plate 112.

[0053] Specifically, the air floating plate 112 is located between the substrate 111 and the cutting module 30, and the air floating plate 112 is connected to the substrate 111 to form an interlayer chamber 12, that is, when the automatic walking device 1 walks on a preset ground to perform corresponding work, the air floating plate 112 is located on a side relatively close to the preset ground, and the substrate 111 is located on a side relatively close to the preset ground.

[0054] Furthermore, since the cutting module 30 is opposite to the chassis 11 and is disposed on a side of the chassis 11 close to the preset ground, the position of the air flotation hole 113 opened on the air flotation plate 112 is opposite to the position of the cutting module 30, and the air flow formed by the air flotation module 40 passing gas into the interlayer chamber 12 will be directly sprayed to the cutting module 30, specifically, to the cutter disc 311 and the cutting blade 312 on the cutting assembly 31, thereby directly blowing away the grass clippings accumulated on the cutter disc 311 and the top of the cutting disc 311, as well as the grass clippings splashed to the bottom of the substrate 111, thereby having a better cleaning effect.

[0055] In an optional embodiment, the substrate 111 includes a central portion 114 and an extension portion 115 connected to the periphery of the central portion 114 and extending toward the cutting module 30 , wherein the central portion 114 is spaced apart from the air flotation plate 112 , and the central portion 114 is connected to the air flotation plate 112 via the extension portion 115 .

[0056] Specifically, the central portion 114 and the air flotation plate 112 are spaced apart from each other, and the formation position of the interlayer chamber 12 is located between the central portion 114 and the air flotation plate 112, and the extension portion 115 is arranged around the circumference of the interlayer chamber 12, so that the gas introduced into the interlayer chamber 12 by the air flotation module 40 will flow out in a concentrated manner from the air flotation holes 113 arranged on the air flotation plate 112.

[0057] Furthermore, at least a portion of the structure of the air flotation module 40 is accommodated in the interlayer chamber 12 , so that the gas output by the air flotation module 40 can quickly fill the interlayer chamber 12 and then flow out from the air flotation holes 113 .

[0058] In an optional embodiment, the distance between the central portion 114 and the air floating plate 112 is not less than 5 mm. More preferably, the distance between the central portion 114 and the air floating plate 112 is 5-25 mm.

[0059] It should be understood that the spacing between the central portion 114 and the air flotation plate 112 should ensure a sufficient distance so that the sandwich chamber 12 is sufficient to accommodate at least a portion of the structure of the air flotation module 40 .

[0060] In an optional embodiment, a mounting position 116 for connecting to the cutting module 30 is provided on the substrate 111 , a mounting notch 117 opposite to the mounting position 116 is formed on the air flotation plate 112 , and a plurality of air flotation holes 113 are opened around the mounting notch 117 .

[0061] Specifically, the mounting position 116 is set at the central portion 114 of the base plate 111, and the cutting assembly 31 of the cutting module 30 is movably mounted at the mounting position 116 on the base plate 111 through the mounting notch 117 of the air floating plate 112, and when the cutting assembly 31 is mounted at the mounting position 116, the cutting assembly 31 extends to the outside of the air floating plate 112 through the mounting notch 117 formed by the air floating plate 112. Therefore, when the automatic walking device 1 walks on the preset ground to perform corresponding work, the cutting assembly 31 is located on the side of the chassis 11 close to the preset ground, and the cutting assembly 31 can rotate relative to the base plate 111 to perform a cutting action on the target object on the preset ground.

[0062] Since the plurality of air flotation holes 113 are provided around the mounting notch 117 , the airflow generated by the air flotation module 40 can more evenly and effectively clean the cutting assembly 31 and the cutting module 30 , especially when the cutting drive assembly 32 drives the cutting assembly 31 to rotate.

[0063] In an optional embodiment, the arrangement density of the air flotation holes 113 on the air flotation plate 112 close to the installation notch 117 is greater than the arrangement density on the side away from the installation notch 117 .

[0064] Exemplarily, the plurality of air flotation holes 113 are arranged in at least two circles on the air flotation plate 112 , and the density of the air flotation holes 113 in the inner region close to the installation notch 117 is greater than the density of the air flotation holes 113 in the outer region away from the installation notch 117 .

[0065] It should be understood that when the cutting component 31 cuts the target object, some foreign matter will splash to the top of the cutting component 31, especially the area near the top of the blade 311 close to the output shaft, which will easily cause the peripheral side of the output shaft to be blocked by foreign matter (such as grass). Therefore, the flotation holes 113 will be arranged more densely in the inner area near the installation notch 117.

[0066] In an optional embodiment, the air flotation holes 113 are in the shape of circular holes. Specifically, the air flotation holes 113 have the same diameter at all locations. It should be understood that the air flow output by the circular air flotation holes 113 is more evenly distributed, which is conducive to providing a uniform and stable cleaning effect.

[0067] In another optional embodiment, the diameter of the passage opening of the air flotation hole 113 facing the cutting module 30 is smaller than the diameter of the passage opening on the side away from the cutting module 30 .

[0068] Specifically, in the embodiment of the present application, the air flotation hole 113 is a conical hole, the corresponding space is conical, and the diameter of the passage opening of the air flotation hole 113 facing the cutting module 30 is smaller than the diameter of the passage opening on the side away from the cutting module 30. It should be understood that the conical air flotation hole 113 can effectively increase the intensity of the air flow ejected from the air flotation hole 113.

[0069] In addition, for the multiple air flotation holes 113 provided on the air flotation plate 112, different shapes can be set for different air flotation holes 113. For example, in the inner area of ​​the air flotation plate 112, the air flotation holes 113 can be set as conical holes to increase the intensity of the air flow ejected from the air flotation holes 113, so as to effectively clean the sides of the output shaft where grass clogging is more serious, while in the outer area of ​​the air flotation plate 112, the air flotation holes 113 can be set as circular holes.

[0070] The air flotation module 40 is described in detail below:

[0071] See also Figure 5 In an optional embodiment, the flotation module 40 includes at least a pipeline component 41 and a power component 42, the input end of the pipeline component 41 is connected to the outside, the output end of the pipeline component 41 is connected to the interlayer chamber 12, and the power component 42 is connected to the pipeline component 41 and is used to provide power for the gas flow in the pipeline component 41.

[0072] Specifically, the power assembly 42 is at least used to provide power for the gas to flow from the input end to the output end of the pipeline assembly 41 , so as to supply external gas to the interlayer chamber 12 through the pipeline assembly 41 .

[0073] To further explain, the input end of the pipeline component 41 can be connected to the outside atmosphere so that the gas in the atmosphere can be transported to the interlayer chamber 12 under the drive of the power component 42, or it can be connected to a preset gas container so that the gas in the gas container can be transported to the interlayer chamber 12 under the drive of the power component 42.

[0074] In an optional embodiment, the pipeline assembly 41 at least includes:

[0075] A first air guide tube 411, wherein a first end of the first air guide tube 411 is in communication with the outside, and a second end of the first air guide tube 411 is in communication with an input end of the power assembly 42;

[0076] A second air guide pipe 412, a first end of the second air guide pipe 412 is connected to an output end of the power assembly 42;

[0077] The first air blowing pipe 413 has a first end connected to the second end of the second air guide pipe 412 , and the first air blowing pipe 413 is formed with a first air blowing port 414 , and the space inside the first air blowing pipe 413 is connected to the interlayer chamber 12 through the first air blowing port 414 .

[0078] Specifically, driven by the power assembly 42 , external gas can flow into the interlayer chamber 12 along at least the gas flow path formed by the first gas pipe 411 , the power assembly 42 , the second gas pipe 412 , the first gas blowing pipe 413 and the first gas blowing port 414 .

[0079] Exemplarily, in the air flotation module 40 , at least a portion of the first air guide pipe 411 , the power assembly 42 , the second air guide pipe 412 , and the first air blowing exhaust pipe 413 are accommodated in the interlayer chamber 12 .

[0080] In an optional embodiment, the first end and the second end of the third exhaust pipe are connected to each other, and the pipe assembly 41 further includes:

[0081] A third air guide pipe 415, wherein a first end of the third air guide pipe 415 is connected to a second end of the first air blowing exhaust pipe 413;

[0082] The second air blowing pipe 416 has a first end connected to the second end of the third air guide pipe 415 , and a second air blowing port 417 is formed on the second air blowing pipe 416 , and the space inside the second air blowing pipe 416 is connected to the interlayer chamber 12 through the second air blowing port 417 .

[0083] Illustratively, in the air flotation module 40 , at least a portion of the first air pipe 411 , the power assembly 42 , the second air pipe 412 , the first air blowing exhaust pipe 413 , the third air pipe 415 and the second air blowing exhaust pipe 416 are accommodated in the interlayer chamber 12 .

[0084] Specifically, in this embodiment, the external gas can not only flow into the interlayer chamber 12 along the gas flow path formed by the first air duct 411, the power assembly 42, the second air duct 412, the first air blowing exhaust pipe 413 and the first air blowing port 414, but also flow into the interlayer chamber 12 along the gas flow path formed by the first air duct 411, the power assembly 42, the second air duct 412, the first air blowing exhaust pipe 413, the third air duct 415, the second air blowing exhaust pipe 416 and the second air blowing port 417.

[0085] It should be understood that the solution of arranging the first air blowing pipe 413 and the second air blowing pipe 416 in the interlayer chamber 12 improves the uniformity of supplying the external gas to the interlayer chamber 12. Exemplarily, the first air blowing pipe 413 and the second air blowing pipe 416 are symmetrically arranged in the interlayer chamber 12.

[0086] It should be understood that the arrangement of the first air blowing pipe 413 and the second air blowing pipe 416 in the interlayer chamber 12 is only an example. When a higher uniformity of gas supply is required, a greater number of air blowing pipes may be provided in the interlayer chamber 12 .

[0087] It should be noted that the number of first air outlets 414 provided on the first air outlet pipe 413 may be one, two or more. In an optional embodiment, at least two first air outlets 414 are provided, and at least two first air outlets 414 are evenly distributed in the extension direction of the first air outlet pipe 413.

[0088] It should be understood that when the first air blowing pipe 413 is provided with greater than or equal to two first air blowing ports 414, the pipeline assembly 41 can supply external gas to the interlayer chamber 12 more evenly, and allow the introduced gas to fill the entire interlayer chamber 12 faster, thereby improving the uniformity of the air flow intensity ejected from different air flotation holes 113 on the air flotation plate 112.

[0089] In an optional embodiment, at least two second air blowing ports 417 are provided, and the at least two second air blowing ports 417 are evenly distributed in the extension direction of the second air blowing pipe 416 .

[0090] Specifically, similar to the arrangement on the first air blowing pipe 413, the number of second air blowing ports 417 arranged on the second air blowing pipe 416 may be one, two or more, and further, at least two second air blowing ports 417 are evenly arranged in the extension direction of the second air blowing pipe 416. It should be understood that when the second air blowing pipe 416 is provided with more than or equal to two first air blowing ports 414, the pipeline assembly 41 can more evenly supply the external gas to the interlayer chamber 12, and make the introduced gas fill the entire interlayer chamber 12 faster, thereby improving the uniformity of the air flow intensity ejected from different air flotation holes 113 on the air flotation plate 112.

[0091] In summary, the embodiment of the present application provides an automatic walking device 1, including: a main body 10, which is provided with a chassis 11, and the chassis 11 forms an interlayer chamber 12 with an air flotation hole 113; a moving module 20, used to drive the main body 10 to move; a cutting module 30, the cutting module 30 can move relative to the chassis 11 to perform a cutting action, wherein the opening direction of the air flotation hole 113 is opposite to the cutting module 30; an air flotation module 40, which is arranged on the chassis 11 and is used to introduce gas into the interlayer chamber 12 to spray airflow toward the cutting module 30 through the air flotation hole 113.
