[0030] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.
[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0032] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0033] like Figures 1 to 8 As shown, a lawnmower is provided according to a first aspect of the embodiments of this application, comprising: a lawnmower body 110; at least two cutting elements 120, the cutting elements 120 being rotatably connected to the lawnmower body 110; and an adjustment assembly 130, the adjustment assembly 130 being connected to the cutting elements 120, the adjustment assembly 130 being used to drive at least one cutting element 120 to move independently up and down relative to the lawnmower body 110.
[0034] The lawnmower provided in this embodiment includes a lawnmower body 110, at least two cutting elements 120, and an adjustment component 130. The adjustment component 130 is used to drive at least one cutting element 120 to rise and fall independently relative to the lawnmower body 110. Based on this, when the lawnmower is working, at least two cutting elements 120 rotatably connected to the lawnmower body 110 start operating. The adjustment component 130 connects each cutting element 120, and according to operational needs, can drive at least one cutting element 120 to rise and fall independently relative to the lawnmower body 110, flexibly adjusting the ground height of the cutting element 120. The remaining cutting elements 120 can maintain their original height or be adjusted synchronously. Cutting operations are achieved through the rotation of the cutting elements 120, and the independent lifting function allows different cutting elements 120 to adapt to different working conditions, completing differentiated cutting operations without overall adjustment.
[0035] The lawnmower provided in this application embodiment uses an adjustment component 130 to independently raise and lower at least one cutting element 120 relative to the lawnmower body 110, overcoming the limitation of synchronous raising and lowering of the cutting element 120 in related technologies. In complex conditions such as high-density vegetation, segmented cutting can be achieved by differentially adjusting the height of the cutting element 120, reducing resistance during a single cut, avoiding missed cuts, and improving cut smoothness. Under normal operating conditions, the height can be adjusted synchronously to ensure cutting efficiency. Simultaneously, the independent raising and lowering design reduces wear and tear on the cutting element 120, extends its service life, adapts to various lawn cutting needs, and enhances the practicality and adaptability of the equipment.
[0036] It is understandable that using the adjustment component 130 to independently raise and lower at least one cutting element 120 relative to the lawnmower body 110 means that the target cutting element 120 can be raised and lowered individually through the adjustment component 130. For example, there can be three cutting elements 120, and one of the three cutting elements 120 can be driven independently by the adjustment component 130, while the other two cutting elements 120 are driven synchronously. Alternatively, there can be two cutting elements 120, and both cutting elements 120 can be driven independently. Or, there can be three cutting elements 120, and all three cutting elements 120 can be driven and adjusted independently. Of course, there can also be multiple cutting elements 120, and some of the multiple cutting elements 120 can be driven independently, while others can be driven synchronously. Alternatively, all of the multiple cutting elements 120 can be driven independently. As long as at least one cutting element 120 can be independently controlled to raise and lower, the technical effects of avoiding missed cuts, improving cutting flatness, and increasing the service life of the cutting element 120 can be achieved.
[0037] like Figures 1 to 8 As shown, in one feasible implementation, there are two cutting elements 120, and the adjusting component 130 is used to drive each cutting element 120 to rise and fall independently relative to the lawnmower body 110.
[0038] This technical solution further provides the arrangement of two cutting elements 120, each of which can be independently driven for lifting and lowering. When the lawnmower is dealing with dense vegetation, the ground clearance of the two cutting elements 120 can be set differently: one is adapted to the target height to be cut, and the other is higher than the target height. This segmented cutting reduces the resistance of a single cut, avoids missed cuts, and ensures a smooth lawn cut. Under normal operating conditions, they can be adjusted to the same height simultaneously to improve cutting efficiency. The independent lifting design overcomes the limitations of synchronous lifting and lowering in related technologies, reduces wear and tear on the cutting elements 120, extends their service life, and adapts to various lawn cutting needs, significantly improving the equipment's practicality and adaptability to different operating conditions.
[0039] like Figures 1 to 8 As shown, in one feasible implementation, there are multiple cutting elements 120, and the adjustment component 130 is used to drive each cutting element 120 to rise and fall independently relative to the lawnmower body 110.
[0040] In this technical solution, there can be multiple cutting components 120, and each cutting component 120 can be independently raised and lowered relative to the lawnmower body 110 under the drive of the adjustment component 130. When the lawnmower is facing high-density vegetation, the ground clearance of each cutting component 120 can be precisely differentiated according to the height and density differences of the vegetation. Some cutting components 120 are adapted to the target cutting height, while the remaining cutting components 120 are set to different levels above the target height, realizing multi-stage gradient cutting, significantly reducing the resistance of a single cut, and completely avoiding the problems of missed cuts and uneven cuts. Under normal working conditions, all cutting components 120 can be adjusted to the same height, significantly improving cutting efficiency. The independent lifting design overcomes the limitation of synchronous lifting and lowering of lawnmower cutting components 120 in related technologies, reducing wear and tear on cutting components 120, extending their service life, and flexibly adapting to different lawn conditions and cutting needs, greatly improving the equipment's adaptability, operational flexibility, and practicality.
[0041] like Figures 1 to 8 As shown, in one feasible embodiment, there are multiple cutting elements 120, and the adjustment component 130 is used for at least one cutting element 120 to rise and fall independently relative to the lawnmower body 110, and the adjustment component 130 is used to drive at least two cutting elements 120 to rise and fall synchronously relative to the lawnmower body 110.
[0042] In this technical solution, there are multiple cutting elements 120, some of which are independently controlled for raising and lowering, while others can be synchronously controlled for raising and lowering. Based on this, when the lawnmower is working with dense vegetation, the adjustment component 130 can be used to allow at least one cutting element 120 to independently rise and fall to a suitable height, while simultaneously driving at least two other cutting elements 120 to rise and fall synchronously to another level, forming a gradient cutting mode. This significantly reduces the resistance of a single cut, avoids missed cuts, and ensures a smooth and uniform lawn cut. Under normal operating conditions, all cutting elements 120 can be driven to rise and fall synchronously to the same height, significantly improving cutting efficiency. This dual-adjustment design overcomes the functional limitations of related lawnmower technologies, meeting the differentiated cutting needs under complex conditions while ensuring efficiency in normal operations, reducing wear and tear on the cutting elements 120, extending their service life, and greatly improving the equipment's adaptability, operational flexibility, and overall practicality.
[0043] like Figures 1 to 3 As shown, in one feasible implementation, the adjustment assembly 130 includes a first adjustment unit 131, and each cutting piece 120 that needs to be driven to rise and fall independently is connected to a first adjustment unit 131.
[0044] This technical solution provides an adjustment component 130, in which each cutting element 120 requiring independent lifting and lowering is connected to a first adjustment unit 131. This means that each cutting element 120 requiring independent lifting and lowering is equipped with a first adjustment unit 131, enabling a one-to-one correspondence between the cutting element 120 and the first adjustment unit 131. This design allows for precise control of the independent lifting and lowering of a single cutting element 120 relative to the mower body 110. In high-density vegetation conditions, different cutting element 120 heights from the ground can be flexibly set, reducing resistance and preventing missed cuts through segmented cutting, ensuring a smooth cut. In normal operating conditions, the height can be adjusted to the same level as other cutting elements 120 to improve efficiency. Simultaneously, the independent drive structure reduces the cascading effects of failures, extends equipment lifespan, and significantly improves the mower's adaptability and operational reliability.
[0045] like Figures 1 to 3 As shown, in one feasible implementation, the first adjustment unit 131 includes: a first power member 1311; a first transmission member 1312, the output end of the first power member 1311 being connected to the first transmission member 1312; a connecting rod 1313, the first transmission member 1312 being connected to the connecting rod 1313, and the cutting member 120 being connected to the connecting rod 1313.
[0046] In this technical solution, the structure of the first adjustment unit 131 is further provided. The first adjustment unit 131 may include a first power component 1311, a first transmission component 1312, and a connecting rod 1313. After the lawnmower is started, the first power component 1311 of the first adjustment unit 131 outputs power, and its output end drives the connected first transmission component 1312 to rotate. The first transmission component 1312 is connected to the connecting rod 1313 and drives the connecting rod 1313 to move through transmission action, thereby driving the cutting component 120 connected to the connecting rod 1313 to move. Each cutting component 120 corresponds to an independent first adjustment unit 131, and can achieve independent lifting and lowering adjustment relative to the lawnmower body 110 through the cooperation of its own first power component 1311, first transmission component 1312, and connecting rod 1313 to meet different cutting height requirements. Through the synergistic effect of the first power component 1311, first transmission component 1312, and connecting rod 1313, the independent lifting and lowering of the cutting component 120 is precisely controlled. When dealing with dense vegetation, the height of each cutting component can be adjusted by 120mm for segmented cutting to reduce resistance, avoid missed cuts, and ensure a smooth cut. Under normal working conditions, the height can be adjusted simultaneously to improve efficiency. The independent drive design reduces the cascading effects of failures, extends equipment life, adapts to various lawn conditions, and significantly improves the lawnmower's operational flexibility and practicality.
[0047] like Figures 1 to 3 As shown, in one possible implementation, the first transmission member 1312 includes a cam, and a protrusion is formed on the connecting rod 1313, which abuts against the cam when the first power member 1311 is activated.
[0048] This technical solution further provides the design of the first transmission component 1312. The first transmission component 1312 employs a cam, with a connecting rod 1313 forming a protrusion. After the first power component 1311 is activated, the protrusion abuts against the cam, achieving precise transmission for the independent lifting and lowering of the cutting component 120. The stable transmission through the cooperation of the cam and the protrusion allows for precise control of the lifting stroke of the cutting component 120, ensuring accurate adjustment of the ground clearance. In dense vegetation, segmented cutting can be achieved by precisely adjusting the height of each cutting component 120, reducing resistance and preventing missed cuts; synchronous adjustment ensures efficient operation under normal working conditions. This structure has low transmission loss, reducing wear on the cutting component 120 and the adjustment component 130, extending equipment life, and improving the operational stability and adaptability of the lawnmower.
[0049] like Figures 4 to 8 As shown, in one feasible implementation, the adjustment assembly 130 includes: a second adjustment unit 132, wherein there are at least two cutting pieces 120 that need to be independently driven to rise and fall, and the second adjustment unit 132 is connected to all the cutting pieces 120 that need to be independently driven to rise and fall.
[0050] This technical solution further provides another style of adjustment component 130, which may include a second adjustment unit 132. The second adjustment unit 132 can connect to at least two cutting elements 120 that require independent lifting and lowering. This design achieves independent lifting and lowering control of multiple cutting elements 120 through a single second adjustment unit 132, simplifying the equipment structure and reducing manufacturing costs and maintenance difficulty. In high-density vegetation conditions, the ground clearance of each cutting element 120 can be flexibly and differentially adjusted, with some parts adapting to the target height and others exceeding it, achieving segmented cutting, reducing cutting resistance, avoiding missed cuts, and ensuring a smooth cut. Under normal operating conditions, the height can be adjusted synchronously, improving work efficiency. Its integrated connection design balances the flexibility of independent adjustment with the efficiency of synchronous operation, reducing component wear, extending equipment life, and significantly improving the adaptability, practicality, and economy of the lawnmower.
[0051] like Figures 4 to 8 As shown, in one feasible implementation, the second adjustment unit 132 includes: a second power component 1321; a second transmission component 1322, wherein each cutting component 120 that needs to be independently driven to rise and fall is connected to a second transmission component 1322, and the second power component 1321 is switchably connected to all second transmission components 1322.
[0052] This technical solution further provides the design of the second adjustment unit 132, which may include a second power component 1321 and a second transmission component 1322. During lawnmower operation, the second power component 1321 of the second adjustment unit 132 is activated, forming a switchable connection with the second transmission component 1322 corresponding to each cutting component 120. When a single cutting component 120 needs independent adjustment, the second power component 1321 switches to the second transmission component 1322 of that cutting component 120, driving the cutting component 120 to independently rise and fall relative to the lawnmower body 110. When multiple cutting components 120 need simultaneous adjustment, the second power component 1321 simultaneously connects to the corresponding second transmission component 1322 to achieve synchronous rising and falling. By switching the power connection, the height adjustment requirements of the cutting components 120 under different working conditions are met, and the cutting operation is completed in conjunction with the rotation of the cutting components 120. The switchable connection design of a single second power component 1321 with multiple second transmission components 1322 simplifies the overall structure of the adjustment assembly 130 and reduces equipment cost and maintenance difficulty. When dealing with dense vegetation, the power connection can be flexibly switched, and the height of each cutting component can be adjusted by 120mm to achieve segmented cutting, reduce resistance, and avoid missed cuts; under normal working conditions, synchronous adjustment can be made to improve efficiency. The stable power switching transmission reduces component wear, extends equipment life, and significantly improves the adaptability and economic efficiency of the lawnmower.
[0053] like Figures 4 to 8 As shown, in one feasible embodiment, the second transmission member 1322 includes an output shaft 13221 and a clutch 13223, wherein the clutch 13223 is connected to the output shaft 13221 and the second power member 1321.
[0054] This technical solution further provides a design for the second transmission component 1322, which may include an output shaft 13221 and a clutch 13223. During lawnmower operation, the second power component 1321 is activated, and the clutch 13223 of the second transmission component 1322 connects the output shaft 13221 and the second power component 1321. When a specific cutting element 120 needs independent adjustment, the corresponding clutch 13223 is engaged, while the others are disengaged. The second power component 1321 drives the cutting element 120 to rise and fall via the output shaft 13221. When synchronous adjustment is required, multiple clutches 13223 are engaged simultaneously, and the second power component 1321 drives the corresponding cutting element 120 to rise and fall synchronously, coordinating with the rotation of the cutting element 120 to complete cutting operations under different working conditions. The second transmission component 1322 adopts a combined design of the output shaft 13221 and the clutch 13223. By switching the clutch 13223 on and off, the independent or synchronous raising and lowering control of multiple cutting elements 120 by a single second power component 1321 can be achieved. The streamlined structure reduces equipment costs and maintenance complexity. In high-density vegetation conditions, the cutting section height can be adjusted up to 120mm for segmented cutting, reducing resistance and preventing missed cuts; in normal operating conditions, synchronous adjustment improves efficiency. The stable and reliable transmission reduces component wear, extends equipment lifespan, and significantly enhances the lawnmower's adaptability and economic efficiency.
[0055] like Figures 1 to 8 As shown. In some examples, the lawnmower may also include a trimmer 140, which is connected to the bottom of the lawnmower body 110 and positioned at the edge of the lawnmower body 110. For the edge grass at the junction of the lawn and flower beds, walls, roads, etc., the trimmer 120 may not be able to completely cover it due to the limitations of the machine structure. By positioning the trimmer 140 at the edge of the lawnmower body 110, it can accurately cut the grass at the boundary, avoid missing the edge, and make the lawn cut more neatly.
[0056] like Figure 11 As shown, a control method is proposed according to a second aspect of the embodiments of this application, applied to a lawnmower including at least two cutting elements, the control method comprising: Step 201: Obtain vegetation information for the area to be cut; Step 202: Based on the height of the target to be cut and the vegetation information, independently adjust the height of the cutting component off the ground and perform the cutting operation.
[0057] The control method provided in this application embodiment, since it is applied to lawnmowers as described in any of the above technical solutions, therefore possesses all the beneficial effects of lawnmowers described in the above technical solutions.
[0058] The control method provided in this application first acquires vegetation information of the area to be cut, and then adjusts the height of the cutting component from the ground based on the target height and vegetation information before performing the cutting. Acquiring vegetation information allows for accurate understanding of the lawn condition, providing data support for height adjustment; the adjustment logic based on the target height and vegetation information allows the cutting component to adapt to different working conditions. For example, when dealing with dense vegetation, the height of the cutting component can be set differently to achieve segmented cutting, avoiding missed cuts, improving cutting smoothness, and reducing cutting resistance; under normal working conditions, the height can be adjusted synchronously to ensure efficiency. This method allows lawnmowers to break free from fixed cutting modes, flexibly adapt to diverse lawn needs, extend the life of the cutting components, and significantly improve operational accuracy, flexibility, and overall practicality.
[0059] In one feasible implementation, the step of obtaining vegetation information of the area to be cut includes: collecting height information and / or density information of the vegetation in the area to be cut.
[0060] This technical solution, by collecting height and / or density information of vegetation in the area to be cut, can accurately grasp the actual condition of the lawn, providing reliable data support for adjusting the height of the cutting components off the ground. It can quickly identify high-density vegetation conditions, ensuring that the height of the cutting components can be adjusted accordingly to achieve segmented cutting, avoid missed cuts, improve cutting smoothness, reduce cutting resistance, extend component life, and make lawnmower operations more precise and adaptable.
[0061] In one feasible implementation, the steps of independently adjusting the ground clearance of the cutting components based on the target height and vegetation information to perform the cutting operation include: when the vegetation information is high-density vegetation, adjusting the ground clearance of the cutting components so that at least two cutting components have different ground clearances, and then performing the cutting operation.
[0062] In this technical solution, when the vegetation information indicates high-density vegetation, the ground clearance of the cutting components is adjusted so that at least two cutting components are at different ground clearances, and then the cutting operation is performed. The high-density vegetation is first initially cut by the higher-positioned cutting component, and then finely trimmed by the cutting component adapted to the target height, achieving segmented cutting. This can significantly reduce the resistance of a single cut, avoid problems such as missed cuts and uneven cuts, and at the same time reduce the wear and tear of the cutting components and extend their service life. Compared with the traditional fixed-height cutting mode, this adjustment logic makes the lawnmower more adaptable to complex lawn conditions, significantly improving the operation quality and equipment practicality in high-density vegetation scenarios.
[0063] In one feasible implementation, at least one cutting element has a ground clearance height adapted to the height of the target to be cut; at least one cutting element has a ground clearance height greater than the height of the target to be cut.
[0064] In this technical solution, at least one cutting element is positioned at a height adapted to the target cutting height, while at least one cutting element is positioned at a height greater than the target height, creating a segmented cutting pattern. High-density vegetation is first initially reduced in height by the higher cutting element, and then finely trimmed by the cutting element adapted to the target height. This significantly reduces single-cut resistance and avoids missed cuts and uneven cuts. This design eliminates the need for multiple round trips, enabling efficient cutting in a single path. This reduces wear and tear on cutting components, extends equipment lifespan, improves operational quality under high-density vegetation conditions, and enhances the adaptability and practicality of the lawnmower.
[0065] Taking some application scenarios as examples, a lawnmower may include two cutting components. When cutting tall or dense grass, the ground height of one cutting component is the target cutting height, and the ground height of the other cutting component is set between the target cutting height and the highest height of the cutting component. (For example, if the cutting component height ranges from 2cm to 10cm, the grass height is 13cm, and the target cutting height is 4cm, one cutting component is set to a height of 4cm, and the other cutting component is set to a height between 4cm and 10cm, preferably 8cm. For tall and dense grass, the grass is first cut to height h2 (8cm) by one cutting component, and then cut to the target height h1 (4cm) by the other cutting component. The cutting process is divided into two height segments, which can be completed in one cutting path, reducing the height of each cut, ensuring cutting quality; it also reduces the resistance of the cutting components and extends their lifespan.)
[0066] It is understandable that when the cutting component performs a cutting operation, under conditions of high-density vegetation, the working mode of the cutting component is to cut counterclockwise from the outside to the inside or clockwise from the inside to the outside on the grassland. Figure 9 and Figure 10 As shown, different cutting parts can adopt different rotation directions during the cutting process, among which... Figure 9 In the middle, located Figure 9 The cutting element on the left is at the target cutting height, and the cutting element on the right is positioned between the target cutting height and the highest point of the cutting element. The left cutting element rotates counter-clockwise from the outside in, while the right cutting element rotates clockwise from the inside out. For example... Figure 10 As shown, the cutting element on the left is at the target cutting height, and the cutting element on the right is positioned between the target cutting height and the highest point of the cutting element. The left cutting element rotates clockwise from the outside in, and the right cutting element rotates counterclockwise from the inside out. Both methods ensure effective cutting.
[0067] In one feasible implementation, when the height of the vegetation in the area to be cut exceeds a first threshold, the vegetation is identified as high-density vegetation. This setting, by establishing a first threshold, allows for the rapid and accurate identification of complex cutting conditions when the vegetation height exceeds this threshold. Based on this determination, the cutting components can be adjusted to differentiated heights in a timely manner to achieve segmented cutting, effectively avoiding missed cuts and uneven cuts, reducing cutting resistance, extending component lifespan, and improving the lawnmower's targeting and efficiency. In some embodiments, the first threshold ranges from 10cm to 15cm.
[0068] In one feasible implementation, when the vegetation density information of the area to be cut exceeds a second threshold, the vegetation information is identified as high-density vegetation. This setting, with a second threshold, allows for rapid and accurate identification of high-density conditions when the vegetation density information of the area to be cut exceeds this second threshold. Based on this determination, the height of the cutting components can be adjusted in a timely and differentiated manner, reducing cutting resistance through segmented cutting, avoiding missed cuts, improving the flatness of the lawn cut, and simultaneously reducing wear and tear on the cutting components, thus enhancing the adaptability and operational efficiency of the lawnmower in high-density vegetation scenarios. In some embodiments, the value of the second threshold ranges from 15,000 plants per square meter to 20,000 plants per square meter.
[0069] In one feasible implementation, when the difference between the height of the vegetation in the area to be cut and the height of the target area is greater than a third threshold, the vegetation is identified as high-density vegetation. By setting a third threshold, when the difference between the height of the vegetation in the area to be cut and the height of the target area is greater than the third threshold, it is identified as high-density vegetation, achieving accurate judgment of complex cutting conditions. Based on this judgment, at least two cutting components can be adjusted to different ground clearances in a timely manner, one adapted to the target height and the other higher than the target height. This segmented cutting significantly reduces the resistance of a single cut, avoiding missed cuts and uneven cuts. No multiple round trips are required; efficient cutting can be completed in a single path, while reducing wear and tear on cutting components, extending equipment life, and significantly improving the operating quality and adaptability of the lawnmower in high-altitude vegetation scenarios. In some embodiments, the third threshold ranges from 6cm to 10cm.
[0070] like Figure 12 As shown, a control device is proposed according to a third aspect of the embodiments of this application for executing the control method of any of the above technical solutions. The control device includes: an information acquisition unit 301, which is used to acquire vegetation information of the area to be cut; and an execution unit 302, which is used to adjust the height of the cutting component off the ground based on the height of the target to be cut and the vegetation information, and to execute the cutting operation.
[0071] The control device provided in this application embodiment, being applied to a lawnmower as described in any of the above technical solutions, therefore possesses all the beneficial effects of the lawnmower described in the above technical solutions.
[0072] The control device provided in this application first acquires vegetation information of the area to be cut through the information acquisition unit 301, and then adjusts the height of the cutting component off the ground and performs cutting through the execution unit 302 in combination with the target height to be cut and the vegetation information. Acquiring vegetation information can accurately grasp the condition of the lawn and provide data support for height adjustment; the adjustment logic based on the target height and vegetation information allows the cutting component to adapt to different working conditions. For example, when facing dense vegetation, the height of the cutting component can be set differently to achieve segmented cutting, avoid missing cuts, improve cutting smoothness, and reduce cutting resistance; under normal working conditions, the height can be adjusted synchronously to ensure efficiency. This method allows the lawnmower to break away from a fixed cutting mode, flexibly adapt to diverse lawn needs, extend the life of the cutting components, and greatly improve the accuracy, flexibility, and overall practicality of operation.
[0073] In one feasible implementation, the information acquisition unit 301 includes a collection unit and / or an information input unit. The collection unit is used to collect the height information and / or density information of the vegetation in the area to be cut. The information input unit is used to receive the height information and / or density information of the vegetation in the area to be cut for input.
[0074] In this technical solution, the information acquisition unit 301 acquires vegetation information through a collection unit and / or an information input unit. The collection unit can directly collect the height and / or density information of the vegetation in the area to be cut, while the information input unit supports manual input of relevant data. This dual acquisition method ensures the comprehensiveness and flexibility of the information. Accurate vegetation information provides a reliable basis for subsequent adjustment of the cutting height, enabling rapid identification of high-density vegetation conditions, ensuring targeted segmented cutting, avoiding missed cuts, improving cutting smoothness, reducing cutting resistance, extending component lifespan, and allowing the lawnmower to adapt to different operating scenarios, significantly improving operational accuracy and practicality.
[0075] It is understandable that the data acquisition units include, but are not limited to, laser rangefinders, ultrasonic sensors, vision cameras (machine vision), infrared sensors, and so on.
[0076] In one feasible implementation, the execution unit 302 is further configured to: adjust the ground clearance of the cutting component when the vegetation information is high-density vegetation, so that the ground clearance of at least two cutting components is different, and perform the cutting operation; wherein, the ground clearance of at least one cutting component is adapted to the height of the target to be cut, and the ground clearance of at least one cutting component is greater than the height of the target to be cut.
[0077] In this technical solution, when the vegetation information indicates high-density vegetation, the ground clearance of the cutting components is adjusted so that at least two cutting components are at different ground clearances, and then the cutting operation is performed. The high-density vegetation is first initially cut by the higher-positioned cutting component, and then finely trimmed by the cutting component adapted to the target height, achieving segmented cutting. This can significantly reduce the resistance of a single cut, avoid problems such as missed cuts and uneven cuts, and at the same time reduce the wear and tear of the cutting components and extend their service life. Compared with the traditional fixed-height cutting mode, this adjustment logic makes the lawnmower more adaptable to complex lawn conditions, significantly improving the operation quality and equipment practicality in high-density vegetation scenarios.
[0078] In this technical solution, at least one cutting element is positioned at a height adapted to the target cutting height, while at least one cutting element is positioned at a height greater than the target height, creating a segmented cutting pattern. High-density vegetation is first initially reduced in height by the higher cutting element, and then finely trimmed by the cutting element adapted to the target height. This significantly reduces single-cut resistance and avoids missed cuts and uneven cuts. This design eliminates the need for multiple round trips, enabling efficient cutting in a single path. This reduces wear and tear on cutting components, extends equipment lifespan, improves operational quality under high-density vegetation conditions, and enhances the adaptability and practicality of the lawnmower.
[0079] In one feasible implementation, the control device further includes a data processing unit, which is configured to: identify vegetation information as high-density vegetation when the height information of vegetation in the area to be cut is greater than a first threshold; and / or identify vegetation information as high-density vegetation when the density information of vegetation in the area to be cut is greater than a second threshold; and / or identify vegetation information as high-density vegetation when the difference between the height information of vegetation in the area to be cut and the height of the target to be cut is greater than a third threshold.
[0080] In this technical solution, by setting a data processing unit and defining at least one of a first, second, and third threshold, high-density vegetation is identified through threshold comparison, enabling accurate judgment of complex cutting conditions. Based on this judgment, at least two cutting components can be adjusted to different ground clearances in a timely manner—one adapted to the target height and the other higher. This segmented cutting significantly reduces the resistance of a single cut, avoiding missed cuts and uneven cuts. No multiple round trips are required; efficient cutting can be completed in a single path, while reducing wear and tear on cutting components, extending equipment lifespan, and significantly improving the mower's operational quality and adaptability in high-altitude vegetation environments.

[0083] The computer-readable storage medium provided in this application first acquires vegetation information of the area to be cut through an information acquisition unit, and then adjusts the height of the cutting component off the ground and performs cutting by combining the target height to be cut with the vegetation information through an execution unit. Acquiring vegetation information allows for accurate understanding of the lawn condition, providing data support for height adjustment; the adjustment logic based on the target height and vegetation information allows the cutting component to adapt to different working conditions. For example, when facing dense vegetation, the height of the cutting component can be set differently to achieve segmented cutting, avoid missing cuts, improve cutting smoothness, and reduce cutting resistance; under normal working conditions, the height can be adjusted synchronously to ensure efficiency. This method allows lawnmowers to break away from fixed cutting modes, flexibly adapt to diverse lawn needs, extend the life of cutting components, and significantly improve operational accuracy, flexibility, and overall practicality.
