The minimum distance from the cutting end to the reference plane; and / or, when the recycling container is fully loaded, the minimum distance from the second end of the recycling container to the reference plane is greater than or equal to the minimum distance from the cutting end to the reference plane; and / or, when the recycling container is unloaded, the distance from the recycling container to the reference plane gradually increases from the first end to the second end of the recycling container; the minimum distance from the first end of the recycling container to the reference plane when it is unloaded is less than or equal to the minimum distance from the second end of the recycling container to the reference plane when it is fully loaded; and / or, the plane containing the bottom of the recycling container is parallel to the reference plane, and the minimum distance from the plane containing the bottom of the recycling container to the reference plane is greater than or equal to the minimum distance from the cutting end to the reference plane.
[0008] Optionally, the recycling container is movably installed on the housing, and the recycling container can switch between a recycling state and a tilting state; when the recycling container is in the recycling state, the recycling container can recycle the material cut by the cutting component, and when the recycling container is in the tilting state, the material in the recycling container can be discharged out of the recycling container; during the process of switching the recycling container from the recycling state to the tilting state, the minimum distance from the recycling container to the reference surface is greater than or equal to the minimum distance from the cutting end to the reference surface.
[0009] Optionally, the garden robot also includes a channel section, one end of which is connected to a cutting component and the other end to a recycling container. The recycling container has an opening structure. When the recycling container is in the recycling state, it is connected to the channel section through the opening structure and can receive materials in the channel section. When the recycling container is in the tilting state, it is connected to the external environment through the opening structure, and the materials in the recycling container can be discharged from the opening structure under the action of gravity.
[0010] Optionally, a recycling channel is provided inside the channel section. One end of the recycling channel is connected to the cutting component, and the other end of the recycling channel is connected to the opening structure when the recycling container is in the recycling state.

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0035] As described in the background section, garden robots have been widely used in the field of garden maintenance with the development of automation technology. Garden robots can automatically complete tasks such as lawn mowing and leaf sweeping, greatly improving the efficiency and convenience of garden operations. Among these, the grass collection frame is a crucial component used by garden robots to collect mowed grass clippings, leaves, and other debris. However, in some existing garden robots, the bottom of the grass collection frame may interfere with the grass during operation, increasing the robot's walking resistance.
[0036] See Figures 1 to 7As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a garden robot, which includes: a housing 10, a cutting part 20, and a recycling part 30. The cutting part 20 includes a cutting component 21, which is mounted on the housing 10. The cutting end of the cutting component 21 is used to cut materials on the working plane of the garden robot. The recycling part 30 includes a recycling container 31, which is mounted on the housing 10 and is used to recycle the materials cut by the cutting component 21. With the working plane as a reference plane, the minimum distance from the cutting end to the reference plane is less than or equal to the minimum distance from the recycling container 31 to the reference plane. The garden robot provided in this embodiment sets the minimum distance from the cutting end of the cutting component 21 to the reference plane to be less than or equal to the minimum distance from the recycling container 31 to the reference plane. This ensures that the height of the residual material on the working plane after being cut by the cutting component 21 is not greater than the lowest position height of the recycling container 31, thereby avoiding interference between the recycling container 31 and materials in the external environment during the operation of the garden robot. This results in lower walking resistance for the garden robot during operation, improving its working efficiency and endurance.
[0037] It should be noted that in this embodiment, the minimum distance from the cutting end to the reference plane refers to the minimum vertical distance from the cutting end to the reference plane, and the minimum distance from the recycling container 31 to the reference plane refers to the vertical distance from the lowest position of the recycling container 31 to the reference plane. The minimum vertical distance from the cutting end to the reference plane is a, and the vertical distance from the lowest position of the recycling container 31 to the reference plane is b, where a≤b.
[0038] In one specific embodiment, the garden robot includes a walking unit 60, which is mounted on the housing 10 and used to drive the garden robot to move. By providing the walking unit 60 on the housing 10, the garden robot can move autonomously on the working plane under the drive of the walking unit 60.
[0039] In some embodiments, the working plane of the garden robot in this embodiment is the plane determined by multiple contact points between the walking part 60 of the garden robot and the ground, such as a horizontal ground or a sloping surface.
[0040] In one specific embodiment, the cutting part 20 is movably mounted on the housing part 10 in the vertical direction. By movably mounting the cutting part 20 on the housing part 10 in the vertical direction, the cutting assembly 21 provided in this embodiment can flexibly adjust the cutting height according to the undulation of the working plane or the thickness of the material, thereby ensuring that the cutting end always maintains a suitable contact distance with the material, and thus effectively improving the cutting efficiency and work quality of the garden robot.
[0041] In one specific implementation, when the cutting section 20 moves to the position with the maximum distance from the reference plane, the minimum distance from the cutting end to the reference plane is less than or equal to the minimum distance from the recycling container 31 to the reference plane. By setting the cutting end of the cutting component 21 to the position with the maximum distance from the cutting section 20 to the reference plane, the minimum distance to the reference plane is less than or equal to the minimum distance from the recycling container 31 to the reference plane. This ensures that the height of the residual material cut by the cutting component 21 at any height on the working plane is no greater than the lowest position height of the recycling container 31. This avoids interference between the recycling container 31 and materials in the external environment during the garden robot's operation, resulting in lower walking resistance for the garden robot and improving its working efficiency and endurance.
[0042] See Figure 6 and Figure 7 As shown, in a specific embodiment, the first end of the recycling container 31 is the bottom end of the recycling container close to the cutting component 21, and the second end of the recycling container 31 is the bottom end of the recycling container away from the cutting component 21. When the recycling container 31 is in an unloaded state, the distance from the first end of the recycling container 31 to the reference surface is less than or equal to the distance from the second end of the recycling container 31 to the reference surface. By setting the recycling container 31 such that the distance from the first end of the recycling container 31 to the reference surface is less than or equal to the distance from the second end of the recycling container 31 to the reference surface when it is in an unloaded state, it is easier for the cut material to smoothly enter the recycling container 31, thereby improving the material collection efficiency of the recycling container 31 in the unloaded state.
[0043] See Figure 6 and Figure 7 As shown, in one specific embodiment, when the recycling container 31 is fully loaded, the distance from the first end of the recycling container 31 to the reference plane is greater than or equal to the distance from the second end of the recycling container 31 to the reference plane. By setting the recycling container 31 such that the distance from the first end of the recycling container 31 to the reference plane is greater than or equal to the distance from the second end of the recycling container 31 to the reference plane when fully loaded, the possibility of material accumulating and overflowing from the recycling container 31 can be reduced to a certain extent. At the same time, the center of gravity of the garden robot when the recycling container 31 is fully loaded can be shifted to the rear, thereby reducing the possibility of the garden robot tipping over due to the center of gravity shifting forward, and improving the reliability of the garden robot.
[0044] In some embodiments, when the recycling container 31 is unloaded, the bottom of the recycling container 31 tilts away from the reference plane from the first end to the second end. When the recycling container 31 is fully loaded, the bottom of the recycling container 31 tilts towards the reference plane from the first end to the second end, or the first end and the second end are at the same height. It should be noted that the recycling container 31 in this embodiment is made of elastic and / or flexible materials and has certain adaptive deformation characteristics. When the recycling container 31 is unloaded, its bottom tilts away from the reference plane from the first end to the second end, forming a structure configuration that is lower in the front and higher in the back. As the amount of material recycled increases, the recycling container 31 undergoes gradual deformation under load. That is, the second end of the recycling container 31 gradually decreases relative to the reference plane until, under full load, the plane where the bottom of the recycling container 31 is located changes to a state where it tilts towards the reference plane from the first end to the second end, or the first end and the second end are at the same height.
[0045] In some embodiments, the recycling container 31 in this embodiment includes a frame and a flexible enclosure component, wherein the frame constitutes the supporting skeleton of the recycling container 31 and provides structural support, and the flexible fabric is enclosed on the frame to form a material containing space for the recycling container 31.
[0046] See Figure 4 and Figure 6 As shown, in a specific embodiment, when the recycling container 31 is in an unloaded state, the distance from the recycling container 31 to the reference surface gradually increases from the first end to the second end, and the minimum distance from the first end of the recycling container 31 to the reference surface is greater than or equal to the minimum distance from the cutting end to the reference surface. By setting the recycling container 31 in the unloaded state to have a gradually increasing distance from the first end to the reference surface, and the distance from the first end of the recycling container 31 to the reference surface being less than the distance from the second end of the recycling container 31 to the reference surface, the recycling container 31 in the unloaded state can form an inclined posture with a lower front and a higher back. Since the distance from the second end of the recycling container 31 to the reference surface is relatively large, the possibility of the second end of the recycling container 31 dragging at the bottom when materials accumulate can be reduced. Setting the minimum distance from the first end of the recycling container 31 to the reference surface to be greater than or equal to the minimum distance from the cutting end to the reference surface can ensure that the bottom of the recycling container 31 in the unloaded state is always higher than the working height of the cutting end, thereby effectively avoiding contact interference between the bottom of the recycling container 31 and the residual material cut by the cutting component 21 on the working plane.
[0047] See Figure 4 and Figure 7As shown, in one specific embodiment, when the recycling container 31 is fully loaded, the minimum distance from the second end of the recycling container 31 to the reference plane is greater than or equal to the minimum distance from the cutting end to the reference plane. Setting the minimum distance from the second end of the recycling container 31 to the reference plane when fully loaded to be greater than or equal to the minimum distance from the cutting end to the reference plane ensures that the bottom of the recycling container 31 is always higher than the working height of the cutting end when fully loaded, thereby effectively avoiding contact interference between the bottom of the recycling container 31 and the residual material cut by the cutting component 21 on the working plane.
[0048] See Figure 6 and Figure 7 As shown, in a specific embodiment, when the recycling container 31 is in an empty state, the distance from the first end of the recycling container 31 to the reference plane gradually increases from the second end to the first end. The minimum distance from the first end of the recycling container 31 to the reference plane in the empty state is less than or equal to the minimum distance from the second end of the recycling container 31 to the reference plane in the fully loaded state. Setting the minimum distance from the first end of the recycling container 31 to the reference plane in the empty state to be less than or equal to the minimum distance from the second end of the recycling container 31 to the reference plane in the fully loaded state allows the center of gravity of the recycling container 31 to gradually shift backward as material is recycled, but without causing the height of the second end of the recycling container 31 to drop below that of the first end of the recycling container 31 in the empty state after material accumulation. This ensures that the center of gravity of the garden robot is always within a reasonable range, effectively reducing the risk of the garden robot tipping over when turning or climbing slopes when the recycling container 31 is under load or fully loaded state, and improving the reliability of the garden robot.
[0049] See Figure 5As shown, in a specific embodiment, the bottom plane of the recycling container 31 is parallel to the reference plane, and the minimum distance from the bottom plane of the recycling container 31 to the reference plane is greater than or equal to the minimum distance from the cutting end to the reference plane. By setting the bottom plane of the recycling container 31 to be parallel to the reference plane and setting the minimum distance from the bottom plane of the recycling container 31 to the reference plane to be greater than or equal to the minimum distance from the cutting end to the reference plane, the bottom of the recycling container 31 can always be higher than the working height of the cutting end during the operation of the garden robot, thereby effectively avoiding contact interference between the recycling container 31 and the residual material after being cut by the cutting component 21. It should be noted that when the bottom plane of the recycling container 31 is parallel to the reference plane, the vertical distance from any point on the bottom plane of the recycling container 31 to the reference plane is the minimum distance from the bottom plane of the recycling container 31 to the reference plane. At this time, the minimum distance from the bottom plane of the recycling container 31 to the reference plane is b1, where a < b1. It should be noted that a rigid plate can be provided at the bottom of the recycling container 31 to keep the bottom of the recycling container 31 flat, thereby improving the structural strength and load-bearing capacity of the recycling container 31.
[0050] It should be noted that when the recycling container 31 is in an unloaded state in this embodiment, the first end of the recycling container 31 has a first lowest position. At this time, the minimum distance from the first end of the recycling container 31 to the reference plane refers to the vertical distance from the first lowest position to the reference plane. When the recycling container 31 is in a fully loaded state, the second end of the recycling container 31 has a second lowest position. At this time, the minimum distance from the second end of the recycling container 31 to the reference plane refers to the vertical distance from the second lowest position to the reference plane. The vertical distance from the first lowest position to the reference plane is b2, and the vertical distance from the second lowest position to the reference plane is b3, where a < b2 < b3.
[0051] In one specific embodiment, the recycling container 31 is movably mounted on the housing 10, and can switch between a recycling state and a tilting state. When the recycling container 31 is in the recycling state, it can recycle the material cut by the cutting component 21. When the recycling container 31 is in the tilting state, the material in the recycling container 31 can be discharged outside the recycling container 31. During the process of switching from the recycling state to the tilting state, the minimum distance between the recycling container 31 and the reference surface is greater than or equal to the minimum distance between the cutting end and the reference surface. Setting the minimum distance between the recycling container 31 and the reference surface during the switching from the recycling state to the tilting state to be greater than or equal to the minimum distance between the cutting end and the reference surface ensures that the recycling container 31 is always higher than the working height of the cutting end during the switching from the recycling state to the tilting state. This effectively avoids contact interference between the recycling container 31 and the residual material cut by the cutting component 21 on the working plane during the switching from the recycling state to the tilting state, and improves the smoothness of the operation of the recycling container 31.
[0052] In one specific embodiment, the garden robot further includes a channel section 40. One end of the channel section 40 is connected to the cutting component 21, and the other end is connected to a recycling container 31. The recycling container 31 has an opening structure. When the recycling container 31 is in the recycling state, it communicates with the channel section 40 through the opening structure and can receive materials from the channel section 40. When the recycling container 31 is in the tilted state, it communicates with the external environment through the opening structure, and the materials in the recycling container 31 can be discharged from the opening structure under the action of gravity. By providing an opening structure on the recycling container 31, the recycling container 31 in the recycling state can communicate with the channel section 40 through the opening structure to receive materials from the channel section 40, and the recycling container 31 in the tilted state can quickly discharge the materials in the recycling container 31 to the external environment through the opening structure and the gravity of the materials themselves.
[0053] It should be noted that the recycling container 31 in this embodiment has a third lowest position during the process of switching from the recycling state to the dumping state. At this time, the minimum distance from the recycling container 31 to the reference plane refers to the vertical distance from the third lowest position to the reference plane, where the vertical distance from the third lowest position to the reference plane is b4, and a < b4.
[0054] In one specific embodiment, a recycling channel is provided in the channel portion 40. One end of the recycling channel is connected to the cutting component 21, and the other end of the recycling channel is connected to the opening structure when the recycling container 31 is in the recycling state. The third end of the recycling container 31 is the end of the inner top surface of the recycling container that is close to the channel portion 40, and the fourth end of the recycling container 31 is the end of the inner top surface of the recycling container that is far away from the channel portion 40. When the recycling container 31 is in the recycling state, the top wall of the recycling channel is virtually extended at the end close to the recycling container 31, and intersects with the top of the recycling container 31 at the intersection area. The horizontal distance from the intersection area to the third end of the recycling container 31 is greater than the horizontal distance from the intersection area to the fourth end of the recycling container 31. By setting the horizontal distance from the junction area to the third end of the recycling container 31 to be greater than the horizontal distance from the junction area to the fourth end of the recycling container 31, the material can be more easily concentrated near the second end of the recycling container 31. Since the second end of the recycling container 31 has a relatively large height and is far away from the channel section 40, it can prevent the minimum distance from the recycling container 31 to the reference plane from decreasing too quickly and prevent the material from accumulating near the opening structure of the recycling container 31 and blocking the opening structure of the recycling container 31.
[0055] It should be noted that when the portion of the top wall of the recycling channel near the recycling container 31 provided in this embodiment is a plane, the virtual extension of the top wall of the recycling channel near the recycling container 31 refers to the imaginary plane formed by the virtual extension of the plane along its extension direction; when the top wall of the recycling channel provided in this embodiment is a curved surface, the virtual extension of the top wall of the recycling channel near the recycling container 31 refers to the tangent plane of the top wall of the recycling channel at its highest point near the recycling container 31. In this case, the junction area is the junction line.
[0056] In one specific embodiment, the distance from the junction area to the third end of the recycling container 31 is greater than or equal to 2 / 3 of the length of the recycling container 31; wherein, the length of the recycling container 31 is the horizontal distance between the third end and the fourth end of the recycling container 31. Setting the distance from the junction area to the third end of the recycling container 31 to be greater than or equal to 2 / 3 of the length of the recycling container 31 can further reduce the probability of material falling into the first end of the recycling container 31, making it easier for the material to be concentrated near the second end of the recycling container 31, further preventing the minimum distance from the recycling container 31 to the reference plane from decreasing too quickly and preventing the material from clogging the opening structure of the recycling container 31.
[0057] In one specific embodiment, the distance from the junction area to the third end of the recycling container 31 is less than or equal to 3 / 4 of the length of the recycling container 31; wherein, the length of the recycling container 31 is the horizontal distance between the third end and the fourth end of the recycling container 31. Setting the distance from the junction area to the third end of the recycling container 31 to be less than or equal to 3 / 4 of the length of the recycling container 31 can prevent the junction area from being too close to the second end of the recycling container 31, reduce the probability of material being bounced back to the first end by the second end of the recycling container 31, and ensure the reliability of material being concentrated near the second end of the recycling container 31.
[0058] It should be noted that the horizontal distance in this embodiment refers to the distance in the direction parallel to the working plane.
[0059] In one specific embodiment, the garden robot further includes a cover plate 50, which includes a movable cover plate movably connected to the recycling container 31. The movable cover plate can switch between a reset state and a displacement state. When the movable cover plate is in the reset state, it partially covers the opening structure. When the movable cover plate is in the displacement state, it avoids the opening structure. When the recycling container 31 switches from the recycling state to the tilting state, the movable cover plate can switch from the reset state to the displacement state under the weight of its own weight or the weight of the material in the recycling container 31. By movably setting a cover plate on the recycling container 31, the garden robot can effectively prevent material splashing and maintain the airtightness of the recycling container 31 by covering the opening structure with the movable cover plate 50 when the recycling container 31 is in the recycling state. When the recycling container 31 is switched to the tilting state, the material in the recycling container 31 can switch the movable cover plate to the displacement state by its own gravity, or the movable cover plate can switch to the displacement state under its own gravity, so that the opening structure is fully exposed to ensure smooth material discharge, effectively improving the reliability of the garden robot.
[0060] In some embodiments, the inner top surface of the recycling container 31 in this embodiment is formed by the lower surface of the cover plate portion 50 and the top lower surface of the recycling container 31.
[0061] In one specific embodiment, the garden robot further includes an elastic buffer section installed at the bottom of the recycling container 31. When the bottom of the recycling container 31 collides with an obstacle in the external environment, the elastic buffer section can cushion the collision between the bottom of the recycling container 31 and the obstacle through elastic deformation. By providing an elastic buffer section at the bottom of the recycling container 31, when the garden robot encounters an obstacle higher than the bottom of the recycling container 31 during its movement, the elastic buffer section can cushion the collision between the obstacle and the bottom of the recycling container 31. The buffering effect of the elastic buffer section can prevent rigid collisions between the recycling container 31 and the obstacle, avoiding damage to the recycling container 31. At the same time, it can also allow the garden robot to pass through obstacles smoothly, improving the reliability and durability of the garden robot.
[0062] In some embodiments, the elastic buffer in this embodiment includes an arc-shaped rubber pad, which is fixedly disposed on the bottom edge of the recycling container 31. The convex surface of the arc-shaped rubber pad faces the reference surface. When the bottom of the recycling container 31 collides with an obstacle, the arc-shaped rubber pad undergoes elastic compression deformation to disperse the impact force, and then resets after the collision. Of course, in other embodiments, the elastic buffer in this embodiment can also be other structures or devices capable of buffering collisions.
