Description

Technical Field

[0001] This utility model relates to the field of lawn mowing equipment technology, and in particular to an intelligent lawn mower. Background Technology

[0002] A smart lawnmower, also known as a lawn mower, lawn trimmer, or lawn trimmer, is a mechanical tool used for trimming lawns, vegetation, etc. When working outdoors, a smart lawnmower may encounter various road conditions. When encountering uneven road conditions, such as local bumps or depressions in the ground, and if the bumps or depressions are high and / or steep (the ground is partially stepped), or when encountering high obstacles, the smart lawnmower may not be able to cross them directly, causing it to get stuck.

[0003] Therefore, a traction mechanism is often included to assist smart lawnmowers in getting out of trouble. During normal operation, this mechanism is stored inside the machine body. However, when assisting with traction, the mechanism may need to come into contact with the ground. Muddy roads often cause the mechanism to become dirty. If it is stored directly inside the machine body, it may soil the internal structure of the smart lawnmower and affect its lifespan.

[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0005] The main purpose of this invention is to propose an intelligent lawnmower that aims to ensure the service life of the intelligent lawnmower.

[0006] To achieve the above objectives, the intelligent lawnmower proposed in this utility model includes:

[0007] body;

[0008] The driving wheel and the traveling wheel are arranged along the direction of travel of the machine body;

[0009] A support structure is installed at the bottom of the fuselage and located between the drive wheel and the traveling wheel. The support structure has a supported state and a retracted state. When the traveling wheel is stuck in a depression in the ground or cannot overcome an obstacle, the support structure switches to the supported state. In the supported state, the support structure can abut against the ground to support the fuselage and assist the traveling wheel in overcoming the depression or obstacle. In the retracted state, the support structure is detached from the ground.

[0010] A cleaning structure is provided on the body or the support structure, and the cleaning structure is capable of cleaning the contact area between the support structure and the ground.

[0011] In one embodiment, the support structure is configured as a retractable lifting support rod mounted on the body. During the process of the support structure changing from the supported state to the retracted state, the lifting support rod rises and slides relative to the cleaning structure so that the cleaning structure cleans the lifting support rod.

[0012] In one embodiment, the bottom of the machine body is provided with a through hole, the lifting support rod is slidably inserted through the through hole to extend out of the machine body, and the cleaning structure is provided at the periphery of the through hole and abuts against the outer peripheral surface of the lifting support rod.

[0013] In one embodiment, the lifting support rod includes a first rod segment and a second rod segment connected to each other. The first rod segment is installed on the machine body, and the second rod segment slides through the lower end of the first rod segment. The cleaning structure is located at the lower end of the first rod segment and abuts against the outer peripheral surface of the second rod segment.

[0014] In one embodiment, the support structure includes a lifting support rod and a support wheel rotatably mounted on the end of the lifting support rod away from the machine body, wherein the lifting support rod is slidably mounted on the machine body;

[0015] During the process of the support structure changing from the supported state to the stored state, or in the stored state, the cleaning structure comes into contact with the support wheel and moves relative to the support wheel to clean the support wheel.

[0016] In one embodiment, the support structure further includes a drive motor disposed on the support wheel and capable of driving the support wheel to rotate relative to the cleaning structure, so that the cleaning structure cleans the support wheel.

[0017] In one embodiment, the cleaning structure includes a cleaning element and a toggle structure; the toggle structure is capable of rotating the support wheel relative to the cleaning element, so that the cleaning structure can clean the support wheel.

[0018] In one embodiment, the cleaning structure is located at the bottom of the body;

[0019] During the storage process, the lifting support rod retracts, causing the support wheel to rise, so that the cleaning structure comes into contact with the support wheel.

[0020] In one embodiment, the cleaning structure includes a drive assembly and a cleaning component, the cleaning component being movably disposed at the lower end of the lifting support rod or the support wheel, and the drive assembly being capable of driving the cleaning component to approach the support wheel;

[0021] During the process of the support structure changing from the supported state to the stored state, the drive component drives the cleaning component to move towards the support wheel, so that the cleaning structure contacts the support wheel, thereby cleaning the support wheel.

[0022] In one embodiment, the cleaning structure includes a cleaning scraper capable of scraping the outer surface of the support structure.

[0023] The technical solution of this utility model involves arranging drive wheels and travel wheels along the direction of travel on the machine body. When the intelligent lawnmower is stuck, if the drive wheels directly drive the machine body, the travel wheels may not be able to provide sufficient traction due to terrain limitations, thus restricting the force exerted by the drive wheels and making it difficult for the intelligent lawnmower to escape. Therefore, a support structure is provided at the bottom of the machine body. In the unstuck state, the support structure moves to a second position abutting the ground to support the machine body, thereby providing an additional support point for the intelligent lawnmower, improving the ground contact force of the machine body, and facilitating the drive wheels to exert force, enabling the drive wheels to drive the machine body, thereby assisting the travel wheels in crossing the concave ground or over obstacles, achieving the purpose of escaping or overcoming obstacles. Furthermore, the support structure is located between the drive wheels and travel wheels, so that when the support structure supports the machine body, it mainly provides support for the side of the machine body where the travel wheels are located, thus avoiding the support structure supporting the side where the drive wheels are located, thereby reducing the possibility of the support structure accidentally reducing the traction of the drive wheels.

[0024] In mowing mode, to reduce the possibility of friction between the support structure and the ground affecting the normal operation of the smart lawnmower, the support structure moves to its first position after being lifted off the ground. Furthermore, a cleaning mechanism is installed on the machine body or support structure to clean the contact points between the support structure and the ground. This cleaning of the support structure before it retracts into the machine body reduces the possibility of dirt or other contaminants entering the machine, thus ensuring the lifespan of the smart lawnmower.

[0037] In existing technologies, intelligent lawnmowers 100 are generally equipped with obstacle avoidance devices to assist them in bypassing obstacles. However, in some working scenarios, the intelligent lawnmower 100 may be unable to bypass obstacles, or it may encounter obstacles unexpectedly. For example, when the ground 2 has a large recessed area 21 or raised area (much larger than the size of the intelligent lawnmower 100 itself), and this recessed area 21 or raised area needs to be mowed, the drive wheel is usually in front to allow the intelligent lawnmower 100 to rush out of the recessed area 21 or climb to the raised area. However, if the recessed area 21 or raised area is high and / or steep, the rear wheels may not be able to pass smoothly, causing the intelligent lawnmower 100 to get stuck. Or, if it accidentally encounters a high obstacle, the rear wheels may also be unable to pass, often requiring manual extrication, which is time-consuming and laborious.

[0038] In view of this, the present invention proposes an intelligent lawnmower 100.

[0039] Please see Figures 1 to 5 In one embodiment of the present invention, the intelligent lawnmower 100 includes a body 1 and drive wheels 101 and travel wheels 102 arranged along the traveling direction of the body 1, and at least the drive wheels 101 are configured as drive wheels; that is, the drive wheels 101 and travel wheels 102 are arranged along the front and rear direction of the body 1, and the intelligent lawnmower 100 can be configured as a two-wheel drive (the travel wheels 102 are driven wheels) or a four-wheel drive (the travel wheels 102 are also drive wheels).

[0040] It is worth noting that the drive wheel 101 and the running wheel 102 are arranged along the direction of travel of the machine body 1. Either the drive wheel 101 or the running wheel 102 can be located at the front of the machine body. Furthermore, when the intelligent lawnmower 100 is dual-wheel drive, if it is rear-wheel drive (i.e., the drive wheel 101 is located at the rear of the machine body 1 and the running wheel 102 is located at the front), the intelligent lawnmower 100 typically reverses to overcome obstacles or get out of trouble. If it is front-wheel drive (i.e., the drive wheel 101 is located at the front of the machine body 1 and the running wheel 102 is located at the rear), the intelligent lawnmower 100 can directly travel forward to overcome obstacles or get out of trouble. In other words, in actual extrication, regardless of whether the intelligent lawnmower 100 is rear-wheel drive or front-wheel drive, the drive wheel 101 always crosses the higher ground 2 or obstacle first. Furthermore, when the intelligent lawnmower 100 is a dual-wheel drive, the walking wheel 102 is often configured as a swivel wheel.

[0041] In one embodiment, when the smart lawnmower 100 is stuck, the drive wheel 101 is located in front of the walking wheel 102, meaning the drive wheel 101 is the first to cross the higher ground 2 or obstacle. However, the walking wheel 102 may get stuck in the recessed ground 2 or be unable to cross the obstacle, causing the smart lawnmower 100 to be in a state of being able to get out of trouble. At this time, if the drive wheel 101 directly drives the body 1 to move, due to terrain limitations, the walking wheel 102 may not be able to provide sufficient traction during the process of getting out of trouble, thus limiting the force exerted by the drive wheel 101 and making it difficult for the smart lawnmower 100 to get out of trouble. Therefore, in order to assist the smart lawnmower 100 in getting out of trouble, a support structure 11 is provided at the bottom of the body 1. In the state of being out of trouble, the support structure 11 moves to a second position that abuts against the ground 2 to support the body 1, so that the drive wheel 101 can drive the body 1 to move, thereby assisting the walking wheel 102 to cross the recessed ground 2 or overcome the obstacle.

[0042] Generally, the intelligent lawnmower 100 has an escape state and a mowing state. The support structure 11 has a support state corresponding to the escape state and a storage state other than the support state. In the escape state, the support structure 11 moves to the second position, so that the lower end of the support structure 11 abuts against the ground 2 to support the body 1, thereby providing an additional support point for the intelligent lawnmower 100, improving the ground contact force of the body 1, thus facilitating the application of force by the drive wheel 101, enabling the drive wheel 101 to drive the body 1 to move, thereby assisting the walking wheel 102 to cross the recessed ground 2 or overcome obstacles, achieving the purpose of escape or obstacle crossing.

[0043] The support structure 11 is located between the drive wheel 101 and the traveling wheel 102, that is, the support structure 11 is located on the side of the drive wheel 101 facing the traveling wheel 102, and is often spaced apart from the drive wheel 101. This allows the support structure 11 to primarily provide support for the side of the vehicle body where the traveling wheel 102 is located when supporting the fuselage 1, thus avoiding the support structure 11 supporting the side where the drive wheel 101 is located, thereby reducing the possibility of the support structure 11 accidentally reducing the grip of the drive wheel 101. Furthermore, there is generally a certain distance between the support structure 11 and the traveling wheel 102, ensuring that the support structure 11 can be stably supported at a higher ground level 2 (the ground level 2 where the drive wheel 101 is located) when supported, thereby reducing the possibility of support structure 11 failure.

[0044] Optionally, along the front-rear direction of the fuselage 1, the support point of the support structure 11 to the fuselage 1 and the support point of the drive wheel 101 to the fuselage 1 are respectively located on opposite sides of the center of gravity of the fuselage 1. That is, the support point of the support structure 11 to the fuselage and the drive wheel 102 are both located on the same side of the center of gravity of the fuselage 1. This allows the support structure 11 to provide support for the vehicle body on the side where the drive wheel 102 is located, thereby avoiding the support structure 11 supporting the side where the drive wheel 101 is located.

[0045] It should be noted that because the weight of the body 1 of the intelligent lawnmower 100 is often unevenly distributed, the center of gravity of the body 1 is not the same as the center of the body 1. Generally, the drive wheel 101 of the intelligent lawnmower 100 is the drive wheel, so the weight of the intelligent lawnmower 100 is often concentrated on the side where the drive wheel 101 is located. Therefore, the support point of the support structure 11 can be located on the side of the body 1 near the drive wheel 102, or at the center of the body 1, or even on the side of the body 1 near the drive wheel 101. Furthermore, the support point of the support structure 11 is not necessarily the same as its installation position. When the support structure 11 is a vertical structure, the support point is the same as its installation position; when the support structure 11 is tilted, the support point is not the same as its installation position.

[0046] In mowing mode, to reduce the possibility of friction between the support structure 11 and the ground 2 affecting the normal operation of the intelligent lawnmower 100, the support structure 11 moves to a first position detached from the ground 2, i.e., switches to a retracted state. At this time, the support structure 11 is at least partially retracted into the body 1. The support structure 11 can rise as a whole, so that at least the support structure 11 is retracted into the body 1, or the support structure 11 can retract itself, so that the lower end of the support structure 11 rises to a certain distance from the ground 2; or the support structure 11 can first retract itself and then rise as a whole to be retracted into the body 1. When the support structure 11 is partially retracted into the body 1, preferably, in the retracted state, the distance from the support structure 11 to the ground 2 is less than the distance from the blade disc to the ground 2, that is, the height of the support structure 11 is higher than the height of the blade disc, thereby further reducing the possibility of the support structure 11 affecting the movement of the intelligent lawnmower 100.

[0047] However, in extreme conditions such as muddy roads, the lower end of the support structure 11 is essentially inserted directly into the muddy ground 2. This means that at least the lower end of the support structure 11 will be covered in mud. If the support structure 11 is directly retracted into the body 1, the mud may be carried directly into the interior space of the body 1, making the interior dirty and difficult to clean. Furthermore, the moisture in the mud will increase the humidity inside the body 1, accelerating rusting of the support structure 11 and the internal structure of the body 1, thus affecting the service life of the intelligent lawnmower 100. Therefore, a cleaning structure 13 is provided on the body 1 or the support structure 11. The cleaning structure 13 can at least clean the contact area between the support structure 11 and the ground, thus cleaning the support structure 11 before it is retracted into the body 1, reducing the possibility of mud and other contaminants entering the interior of the body 1, and thus ensuring the service life of the intelligent lawnmower 100.

[0048] The cleaning structure 13 can clean the support structure 11 by utilizing the retraction motion of the support structure 11 itself during the storage process, thereby cleaning the support structure 11 without the need for an additional drive structure to drive the cleaning structure 13 to move on the surface of the support structure 11. Alternatively, the storage action of the support structure 11 can be paused during the storage process, such as when the lower end of the support structure 11 just leaves the ground 2, at which point the movement of the support structure 11 is paused and the cleaning structure 13 cleans the support structure 11; or the cleaning structure 13 cleans the support structure 11 before the lower end of the support structure 11 is retracted into the body 1.

[0049] Preferably, the cleaning structure 13 is configured as a cleaning scraper, which can scrape the outer surface of the support structure 11, thereby facilitating the cleaning of the outer surface of the support structure 11. The cleaning scraper is made of at least one of rubber, silicone, hard alloy, and polyurethane. Users can choose according to actual road conditions. That is, this solution does not limit the material of the cleaning scraper; as long as it can efficiently remove dirt from the surface of the cleaning scraper, it is within the protection scope of this solution.

[0050] In this design, if the intelligent lawnmower 100 is rear-wheel drive (i.e., the drive wheel 101 is located at the rear of the body 1 and the walking wheels 102 are located at the front of the body 1), the intelligent lawnmower 100 typically reverses to overcome obstacles or get out of trouble in order to improve rear wheel traction and stability. If the intelligent lawnmower 100 is front-wheel drive (i.e., the drive wheel 101 is located at the front of the body 1 and the walking wheels 102 are located at the rear of the body 1), the intelligent lawnmower 100 travels forward to overcome obstacles or get out of trouble. Therefore, in this design, the drive wheel 101 could be either the front or rear wheel of the intelligent lawnmower 100, and the corresponding walking wheel 102 could be either the rear or front wheel of the intelligent lawnmower 100. However, in actual extrication, regardless of whether the intelligent lawnmower 100 is rear-wheel drive or front-wheel drive, the drive wheel 101 always crosses the higher ground 2 or obstacle first. Therefore, in the extrication state, "forward" refers to the direction of travel of the machine body 1 in the extrication state, which may be the same as or different from the direction of travel of the machine body 1 in the mowing state. Furthermore, when the intelligent lawnmower 100 is dual-wheel drive, the walking wheel 102 is often configured as a swivel wheel. It is conceivable that the support structure 11 is typically driven by a drive motor, etc., thereby facilitating the automatic extrication of the intelligent lawnmower 100 without human assistance. This drive structure can utilize some of the intelligent lawnmower 100's own drive structures, or it can be driven by an additional dedicated drive structure.

[0051] Please see Figure 2 and Figure 3In this embodiment of the invention, the support structure 11 is configured as a retractable lifting support rod 111 mounted on the body 1. During the transition from the supported state to the retracted state, the lifting support rod 111 rises and slides relative to the cleaning structure 13, allowing the cleaning structure 13 to clean the lifting support rod 111. Specifically, the lifting support rod 111 is retractably mounted on the body 1 and can rise and fall relative to the body 1. This rod structure is simple in structure and occupies little space, helping to save internal space in the body 1 and facilitating maintenance and replacement. In the unstuck state, the lifting support rod 111 descends until its lower end abuts against the ground 2 to support the body 1, thereby assisting the intelligent lawnmower 100 in unstuck situations. When the support structure 11 is no longer needed, it is retracted, thus changing the support structure 11 from the supported state to the retracted state. Furthermore, during the process of the support structure 11 changing from the supporting state to the storage state, the lifting support rod 111 rises and slides relative to the cleaning structure 13, so that the cleaning structure 13 cleans the lifting support rod 111. Thus, the lifting support rod 111 moves relative to the cleaning structure 13 by its own lifting motion, thereby allowing the cleaning structure 13 to clean the support structure 11. Moreover, there is no need to set up an additional drive structure to drive the movement of the cleaning structure 13, which helps to simplify the structure of the cleaning structure 13 and reduce the space occupied by the cleaning structure 13.

[0052] In this design, the lifting support rod 111 switches between the first and second positions by retracting or expanding, thereby reducing the internal space of the machine body 1. Of course, in other embodiments, the lifting support rod 111 can also be raised or lowered by rotation, thereby being driven by a drive motor to rotate the lifting support rod 111, thus achieving the lifting movement of the lifting support rod 111; the lifting support rod 111 can also be slidably mounted on the machine body 1, allowing the lifting structure to directly achieve raising and lowering by sliding up and down.

[0053] When the lifting support rod 111 is a non-retractable rod, in one embodiment, see [reference needed]. Figure 3The bottom of the body 1 has a through hole 104. A lifting support rod 111 is slidably inserted through the through hole 104 to extend out of the body 1. A cleaning structure 13 is located at the periphery of the through hole 104 and abuts against the outer peripheral surface of the lifting support rod 111. Specifically, the body 1 includes a housing 103, which has a through hole 104 for the lifting support rod 111 to pass through. When the lifting support rod 111 is raised or lowered, it can slide relative to the through hole 104. Therefore, the cleaning structure 13 is located at the periphery of the through hole 104, allowing the lifting support rod 111 to slide through the inner hole formed by the cleaning structure 13. When the lifting support rod 111 rises, the inner side of the cleaning structure 13 rubs against the outer surface of the lifting support rod 111, thereby scraping off the dirt on its surface. The cleaning structure 13 can be directly located on the inner peripheral surface of the through hole 104 or on the side of the through hole 104 facing outwards from the body 1.

[0054] When the lifting support rod 111 is a telescopic rod, in one embodiment, the lifting support rod 111 includes a first rod segment and a second rod segment connected together. The first rod segment is installed on the machine body 1, and the second rod segment slides through the lower end of the first rod segment. The cleaning structure 13 is located at the lower end of the first rod segment and abuts against the outer peripheral surface of the second rod segment. Specifically, the lifting support rod 111 is a telescopic rod, and the first rod segment and the second rod segment are two sections of the telescopic rod that slide against each other. The first rod segment is installed on the machine body 1, and the second rod segment is connected to the lower end of the first rod segment, that is, the first rod segment is the upper section and the second rod segment is the lower section. The second rod segment slides through the first rod segment, that is, a guide hole is opened inside the second rod segment, and the lower section of the telescopic rod is a smaller section. Furthermore, the cleaning structure 13 is mainly used to clean the second rod segment. Therefore, the cleaning structure 13 can be directly installed at the lower end of the first rod segment, such as at the inner periphery of the guide hole. Thus, when the second rod segment slides relative to the first rod segment, it can simultaneously slide relative to the cleaning structure 13, thereby cleaning the second rod segment and achieving the cleaning of the lifting support rod 111.

[0055] The first rod segment can be fixedly installed on the body 1 or movably installed on the body 1. If the first rod segment is fixedly installed on the body 1, the length of the lifting support rod 111 is reduced by its own retraction, thereby achieving the storage of the lifting support rod 111. If the second rod segment is fixedly installed on the body 1, when the lifting support rod 111 needs to be converted to the storage state, the second rod segment can first move upward to reduce the length of the lifting support rod 111, and then the first rod segment drives the second rod segment to move upward to further store the lifting support rod 111 inside the vehicle body. Of course, the first rod segment can also first drive the second rod segment to move upward so that the lifting support rod 111 is stored inside the vehicle, and then the second rod segment moves upward to further reduce the length of the lifting support rod 111, reducing the lifting space required for the support structure 11.

[0056] When the support structure 11 is configured as a lifting support rod 111, and when the lifting support rod 111 assists the body 1 in escaping trouble, the body 1 often drives the lifting support rod 111 forward a certain distance to ensure the body is completely freed. At this time, the lifting support rod 111 and the ground 2 experience sliding friction, resulting in a large frictional force. To reduce friction, in another embodiment of this utility model, please refer to... Figure 4 and Figure 5 The support structure 11 includes a lifting support rod 111 and a support wheel 112 rotatably mounted on the end of the lifting support rod 111 away from the machine body 1. The lifting support rod 111 is slidably mounted on the machine body 1. In the state of being out of trouble, the lifting support rod 111 drives the support wheel 112 to descend, so as to jointly support the machine body 1. That is, a support wheel 112 is added to the lower end of the lifting support rod 111. So when the machine body 1 drives the lifting support rod 111 to move, the lifting support rod 111 and the ground 2 become rolling friction, thereby further reducing friction and facilitating the intelligent lawnmower 100 to get out of trouble.

[0057] To facilitate the storage of the support structure 11 and reduce its space occupation, the support wheel 112 is typically small, at least smaller than the drive wheel 101 and the travel wheel 102. In this case, the cleaning structure 13 primarily cleans the support structure 11 by cleaning the support wheel 112. Therefore, the cleaning structure 13 can scrape the circumferential surface of the support wheel 112, thereby cleaning the mud and dirt from its surface.

[0058] To facilitate cleaning of the support wheel 112, in one embodiment, the support structure 11 further includes a drive motor. The drive motor is located on the support wheel and can drive the support wheel 112 to rotate relative to the cleaning structure 13 to clean the support wheel 112. That is, the support wheel 112 is also configured as a drive wheel, thereby providing forward thrust to the body 1. This allows the support structure 11 to not only support the body 1 to increase the ground contact force of the body 1, but also to drive the body movement together with the drive wheel 101, thereby further facilitating the intelligent lawnmower 100 to get out of trouble. When it needs to be converted to a storage state, the support wheel 112 is lifted off the ground, and the drive structure drives the support wheel 112 to rotate relative to the cleaning structure 13, thereby achieving the purpose of cleaning the support wheel 112. Therefore, in this solution, cleaning is achieved by utilizing the rotation of the support wheel 112 itself, thus eliminating the need to set up a drive motor for the cleaning structure 13, thereby simplifying the cleaning structure 13 and reducing the space occupied by the cleaning structure 13.

[0059] Of course, the support wheel 112 can be a non-drive wheel. In one embodiment, the cleaning structure includes a cleaning component and a toggle structure. The toggle structure can toggle the support wheel so that the support wheel rotates relative to the cleaning component, thereby cleaning the support wheel 112.

[0060] To facilitate the installation of the cleaning structure 13, in one embodiment, see [reference]. Figure 5The cleaning structure 13 is located at the bottom of the body 1. During the retraction process, the lifting support rod 111 retracts, causing the support wheel 112 to rise, so that the cleaning structure comes into contact with the support wheel 112. Since the cleaning structure 13 is located at the bottom of the body 1, during actual cleaning, the lifting support rod 111 first causes the support wheel 112 to rise, and when the support wheel 112 is retracted to the front of the body 1, the support wheel 112 abuts against the cleaning structure 13, thereby allowing the cleaning structure 13 to clean the support wheel 112.

[0061] In another embodiment, see Figure 4 The cleaning structure 13 includes a drive assembly and a cleaning component. The cleaning component is movably disposed at the lower end of the lifting support rod 111 or the support wheel 112. The drive assembly can drive the cleaning component to approach the support wheel 112. During the process of the support structure 11 changing from the supported state to the retracted state, the drive assembly drives the cleaning component to move towards the support wheel 112, so that the cleaning structure 13 contacts the support wheel 112, thereby cleaning the support wheel 112. Alternatively, the cleaning component can be slidably mounted on the lower end of the lifting support rod 111 or the support wheel 112. During the process of the support structure 11 changing from the supported state to the retracted state, the drive assembly slides towards the support wheel 112, so that the cleaning structure 13 contacts the support wheel 112. Or, the cleaning component can be swingably mounted on the lower end of the lifting support rod 111 or the support wheel 112. During the process of the support structure 11 changing from the supported state to the retracted state, the drive assembly swings towards the support wheel 112, so that the cleaning structure 13 contacts the support wheel 112, thereby achieving the purpose of cleaning the support wheel 112. In actual cleaning, it is only necessary to slightly raise the support wheel 112 so that it is off the ground to clean it. Since the rotation of the support wheel 112 generates centrifugal force, the mud and dirt on its surface may splash due to this force. This design reduces the cleaning height of the support wheel 112, thereby reducing the possibility of mud and dirt splashing and contaminating the blade assembly during cleaning. Furthermore, when the cleaning structure 13 is located on the support wheel 112, it is generally positioned on the upper side of the support wheel 112.
