Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a grass collection device and a grass mowing equipment. Background Technology

[0002] Current lawn mowing equipment uses a combination of a brush and a roller to collect fallen leaves and weeds from the lawn. However, the length of the roller in existing lawn mowing equipment is greater than the length of the brush. When the lawn mowing equipment moves backward, the roller is easily affected by the grass, resulting in high resistance and making it difficult to move smoothly, thus resulting in poor grass collection. Utility Model Content

[0003] In view of this, it is necessary to provide a grass collection device and grass cutting equipment that can improve the grass collection effect.

[0004] One embodiment of this application provides a grass collection device, including a main body and a support assembly. The main body includes a roller brush. The support assembly is configured to contact the grass when the main body moves along a first direction. The support assembly is mounted on the main body and located in front of the roller brush. The length of the support assembly along a direction perpendicular to the first direction of the main body is less than the length of the roller brush.

[0005] In some embodiments of this application, during the grass collection process of the grass collection device, by setting the length of the support component along the moving direction of the main body to be less than the length of the roller brush, the contact area between the support component and the grass is reduced, the resistance of the grass roots to the support component when the grass collection device moves is reduced, ensuring that the grass collection device can move smoothly and improving the grass collection effect.

[0006] In some embodiments of this application, the support component includes a connecting portion and at least two supporting portions, with the at least two supporting portions distributed on the connecting portion, and the connecting portion and the opposite sides of any two adjacent supporting portions together forming a clearance zone.

[0007] In some embodiments of this application, by setting a connecting part between the support parts, and keeping the connecting part at a certain height from the grass, a clearance zone is formed between the connecting part and the support part. The clearance zone does not contact the grass, so that the grass in the clearance zone is not squeezed. This can prevent the grass clippings after cutting from falling into the grass roots due to compression, which would make it difficult for the subsequent roller brush to collect the grass clippings. At the same time, by setting the clearance zone, the contact area between the grass and the support component can be reduced, which helps to reduce the resistance between the grass collecting device and the grass, thereby ensuring that the grass collecting device can move smoothly and improving the grass collecting effect of the grass collecting device.

[0008] In some embodiments of this application, the width of the clearance zone along the direction perpendicular to the main body along the first direction is greater than the width of the support portion along the direction perpendicular to the main body along the first direction, so as to reduce the contact area between the grass and the support component.

[0009] In some embodiments of this application, the grass collecting device further includes a swing member, a first end of which is connected to the support assembly, and a second end of which is connected to the main body via a rotating shaft. The swing member is configured to swing along the rotation direction of the rotating shaft. When the main body moves along a first direction, the swing member swings relative to the rotating shaft at a first swing angle, causing the support assembly to rotate relative to the swing member, so that the support assembly is in a first state. When the main body moves along a second direction, the swing member swings relative to the rotating shaft at a second swing angle, causing the support assembly to rotate relative to the swing member, so that the support assembly is in a second state, wherein the first swing angle is greater than the second swing angle.

[0010] In some embodiments of this application, when the grass-collecting device collects grass, the swinging component drives the support assembly to swing at a first swing angle, so that the support assembly provides support force to the grass-collecting device, further raising the roller brush, ensuring that the height between the roller brush and the grass is greater than the height between the support assembly and the grass, so that the roller brush and the grass maintain a certain distance, reducing the resistance between the roller brush and the grass, which is beneficial for effectively collecting grass debris; when the grass-collecting device moves along the second direction, the swinging component swings at a second swing angle, so that the support assembly does not provide support force to the grass-collecting device, thus not forming resistance to the grass-collecting device, reducing the resistance of the grass-collecting device along the second direction, ensuring that the grass-collecting device can move smoothly along the second direction, and improving the grass-collecting effect of the grass-collecting device.

[0011] In some embodiments of this application, the first end of the swing member is provided with a limiting part, and in the second state, the limiting part abuts against the support component to limit the rotation angle of the support component.

[0012] In some embodiments of this application, the main body is provided with a blocking part, which abuts against the swing member in the second state to limit the swing angle of the swing member.

[0013] In some embodiments of this application, the grass collecting device further includes a chute, a first end of which is slidably connected to the support assembly, and a second end of which is connected to the main body via a pivot. The chute is configured to move the support assembly between a first position and a second position to change the pressure exerted by the support assembly on the grass. When the main body moves along a first direction, the support assembly is located at the first position and applies a first pressure to the grass. When the main body moves along a second direction, the support assembly moves from the first position to the second position, and during the movement, the support assembly applies a second pressure to the grass, wherein the first pressure is greater than the second pressure.

[0014] In some embodiments of this application, when the grass collecting device collects grass, the sliding chute drives the support assembly to move between a first position and a second position. When the support assembly is in the first position, it applies a first pressure to the grass and supports itself on the grass, ensuring that the height between the roller brush and the grass is greater than the height between the support assembly and the grass. This maintains a certain distance between the roller brush and the grass, reducing the resistance between the roller brush and the grass, which is beneficial for effectively collecting grass debris. When the grass collecting device moves along the second direction, the support assembly moves from the first position to the second position and applies a second pressure to the grass. Since the applied second pressure is negligible, it does not create resistance to the grass collecting device, reducing the resistance of the grass collecting device along the second direction. This ensures that the grass collecting device can move smoothly along the second direction and improves the grass collecting effect of the grass collecting device.

[0015] In some embodiments of this application, the sliding component is provided with a sliding groove, and both ends of the support component pass through the sliding groove and are slidably connected to the sliding groove. The sliding groove can limit the sliding distance of the support component.

[0016] In some embodiments of this application, at least one of the support parts is in the shape of a roller, which applies uniform pressure to the grass and helps to improve the grass collection effect of the grass collection device.

[0017] In some embodiments of this application, at least one of the support portions has a first contact surface and a second contact surface. The first contact surface is configured to contact the grass surface when moving in a first direction, and the second contact surface is configured to face the grass when moving in a second direction. The first contact surface is configured as an arc surface, which can provide forward resistance when the grass collecting device moves forward, so that the support assembly can be better supported on the grass to raise the roller brush, reduce the resistance of the grass collecting device, and thus improve the grass collecting effect.

[0018] In some embodiments of this application, the connecting part and at least two of the supporting parts are integrally formed, reducing the disassembly and assembly steps and facilitating the disassembly of the grass collection device.

[0019] One embodiment of this application also provides a lawn mowing device, including the aforementioned grass collection device.

[0020] In some embodiments of this application, in the above-mentioned lawn mowing equipment, during the grass collection process of the grass collection device, by setting the length of the support component along the moving direction of the main body to be less than the length of the roller brush, the contact area between the support component and the grass is reduced, the resistance of the grass roots to the support component when the grass collection device moves is reduced, ensuring that the grass collection device can move smoothly and improving the grass collection effect.

[0031] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0032] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0033] It should be noted that when a component is referred to as being "located" on another component, it can be directly on top of the other component or it can be located in the middle of the component. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "above" includes directly above and diagonally above, or simply indicates a higher horizontal level; the term "below" includes directly below and diagonally below, or simply indicates a lower horizontal level.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Current lawnmowers use a combination of a brush and a roller to collect fallen leaves and weeds from the lawn. However, when the existing collection device moves in the first direction, the roller floats due to the support of the grass. But the roller itself has weight, so the height of the brush can only be limited, causing the grass to be squeezed and resulting in poor collection. At the same time, when the collection device moves in the second direction, the diameter of the roller is limited (for example, the diameter of a typical roller is 6cm), which limits its ability to overcome obstacles. Also, the force generated in the second direction causes the brush to move towards the grass, which may cause it to get stuck in the grass. This is not conducive to the collection device moving in the second direction and it is easy to get stuck when moving backward, resulting in poor collection.

[0036] Therefore, to solve the above-mentioned technical problems, embodiments of this application provide a grass-collecting device, which includes a main body and a support assembly. The main body includes a roller brush. The support assembly is used to contact the grass when the main body moves along a first direction. The support assembly is mounted on the main body and located in front of the roller brush. The length of the support assembly along a direction perpendicular to the first direction of the main body is less than the length of the roller brush.

[0037] During the grass collection process, by setting the length of the support component along the main body's moving direction to be less than the length of the roller brush, the contact area between the support component and the grass is reduced, thus reducing the resistance of the grass roots to the support component when the grass collection device moves, ensuring that the grass collection device can move smoothly and improving the grass collection effect.

[0038] The following is in conjunction with the appendix Figures 1 to 8This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a lawn mowing device 1. Wherein, Figure 1 In this context, X1 represents the first direction of the lawn mowing device 1. Figure 2 In this context, X2 represents the second direction of the lawn mowing device 1. Figure 1 and Figure 2 In this context, A represents grassland. The mowing equipment 1 includes a grass collection device 100.

[0040] like Figures 3 to 8 As shown, the grass collection device 100 includes a main body 11 and a support assembly 12. The main body 11 includes a roller brush 110. The support assembly 12 is used to contact the grass when the main body 11 moves in a first direction. The support assembly 12 is mounted on the main body 11 and located in front of the roller brush 110. The length of the support assembly 12 in a direction perpendicular to the first direction of the main body 11 is less than the length of the roller brush 110.

[0041] In some embodiments of this application, during the grass collection process of the grass collection device 100, by setting the length of the support component 12 along the moving direction of the main body 11 to be less than the length of the roller brush 110, the contact area between the support component 12 and the grass is reduced, the resistance of the grass roots to the support component 12 when the grass collection device 100 moves is reduced, and the grass collection device 100 can move smoothly, thereby improving the grass collection effect.

[0042] In some embodiments of this application, the support component 12 includes a connecting portion 120 and at least two support portions 121. The at least two support portions 121 are distributed on the connecting portion 120, and the connecting portion 120 and the opposite sides of any two adjacent support portions 121 together form an air-avoidance area 122.

[0043] In some embodiments of this application, by providing a connecting portion 120 between the support portions 121, and maintaining a certain height between the connecting portion 120 and the grass, a clearance zone 122 is formed between the connecting portion 120 and the support portion 121. The clearance zone 122 does not contact the grass, so that the grass in the clearance zone is not squeezed. This can prevent the grass clippings after cutting from falling into the grass roots due to compression, which would make it difficult for the subsequent roller brush to collect the grass clippings. At the same time, by providing the clearance zone 122, the contact area between the grass and the support component 12 can be reduced, which helps to reduce the resistance between the grass collecting device and the grass, thereby ensuring that the grass collecting device can move smoothly and improving the grass collecting effect of the grass collecting device.

[0044] In some embodiments of this application, the clearance zone 122 is at least partially located within the projection range of the roller brush 110 in the direction perpendicular to the main body of the grass collecting device 100 along the first direction, so that the cut grass clippings are not disturbed by the support component 12 and are smoothly collected by the roller brush 110 into the grass collecting device 100.

[0045] In some embodiments of this application, the width of the clearance zone 122 along the direction perpendicular to the main body 11 along the first direction is greater than the width of the support portion 121 along the direction perpendicular to the main body 11 along the first direction, so as to ensure that the clearance zone has enough space to avoid further reducing the contact area between the grass and the support component 12.

[0046] In some embodiments of this application, the grass-collecting device further includes a swing member 13. A first end of the swing member 13 is connected to a support assembly 12. A second end of the swing member 13 is connected to the main body 11 via a rotating shaft 14. The swing member 13 is configured to swing along the rotation direction of the rotating shaft 14. When the main body 11 moves along a first direction, the swing member 13 swings relative to the rotating shaft 14 at a first swing angle, causing the support assembly 12 to rotate relative to the swing member 13, so that the support assembly 12 is in a first state; when the main body 11 moves along a second direction, the swing member 13 swings relative to the rotating shaft 14 at a second swing angle, causing the support assembly 12 to rotate relative to the swing member 13, so that the support assembly 12 is in a second state. The first swing angle is greater than the second swing angle.

[0047] In some embodiments of this application, when the grass collecting device 100 collects grass, the grass exerts a backward force on the roller brush 110, and the roller brush 110 can float normally. However, due to the weight of the roller brush 110 itself, the height to which the roller brush 110 floats is limited. Therefore, the swing member 13 drives the support component 12 to swing at a first swing angle, so that the support component 12 provides support force to the grass collecting device, so that the support component 12 is in the first state, further raising the roller brush 110, so as to ensure that the height between the roller brush 110 and the grass is greater than the height between the support component 12 and the grass, so that the roller brush 110 maintains a certain distance from the grass, reducing the resistance between the roller brush 110 and the grass, which is beneficial to effectively collect debris on the grass.

[0048] In some embodiments of this application, when the grass collecting device 100 moves along the second direction, the force exerted by the grass on the roller brush 110 causes the roller brush 110 to move toward the grass. The roller brush 110 may insert into the grass, which is not conducive to the movement of the grass collecting device 100 along the second direction. Therefore, the swing member 13 swings at the second swing angle, so that the support component 12 is in the second state. The support component 12 does not provide support force to the grass collecting device 100, so it does not form resistance to the grass collecting device 100, reducing the resistance of the grass collecting device 100 along the second direction, ensuring that the grass collecting device 100 can move smoothly along the second direction, and improving the grass collecting effect of the grass collecting device 100.

[0049] In some embodiments of this application, see Figure 4 and Figure 5 As shown, O1 represents the center of the rotating shaft 14, α represents the first swing angle, and β represents the second swing angle.

[0050] In some embodiments of this application, the first end of the swing member 13 is provided with a limiting part 130. In the second state, the limiting part 130 abuts against the support component 12 to limit the rotation angle of the support component 12. Specifically, the rotation angle of the support component 12 can be set according to the cross-section of the support component 12. For example, if the cross-section of the support component 12 is D-shaped, the rotation angle of the support component 12 can be set to 90 degrees.

[0051] In some embodiments of this application, the main body 11 is provided with a blocking part 111. In the second state, the blocking part 111 abuts against the swing member 13 to limit the swing angle of the swing member 13.

[0052] In some embodiments of this application, the grass-collecting device 100 further includes a chute 15. A first end of the chute 15 is slidably connected to the support assembly 12. A second end of the chute 15 is connected to the main body 11 via a pivot 14. The chute 15 is configured to move the support assembly 12 between a first position and a second position to change the pressure exerted by the support assembly 12 on the grass. When the main body 11 moves along a first direction, the support assembly 12 is located in the first position and applies a first pressure to the grass. When the main body 11 moves along a second direction, the support assembly 12 moves from the first position to the second position, and during this movement, the support assembly 12 applies a second pressure to the grass, the first pressure being greater than the second pressure.

[0053] In some embodiments of this application, when the grass collecting device 100 collects grass, the sliding groove 15 drives the support component 12 to move between a first position and a second position. When the support component 12 is in the first position, the support component 12 applies a first pressure to the grass and supports the grass, ensuring that the height between the roller brush 110 and the grass is greater than the height between the support component 12 and the grass, so that the roller brush 110 maintains a certain distance from the grass, reducing the resistance between the roller brush 110 and the grass, which is beneficial for effectively collecting grass debris. When the grass collecting device 100 moves along the second direction, the support component 12 moves from the first position to the second position. The second position is a position away from the grass, so the second pressure applied by the support component to the grass is very small or negligible, and does not form resistance to the grass collecting device 100, reducing the resistance of the grass collecting device 100 along the second direction, ensuring that the grass collecting device 100 can move smoothly along the second direction, and improving the grass collecting effect of the grass collecting device 100.

[0054] In some embodiments of this application, the sliding member 15 is provided with a sliding groove 150, and both ends of the support component 12 pass through the sliding groove 150 and are slidably connected to the sliding groove 150. The sliding distance of the support component 12 can be limited by the sliding groove 150. For example, the sliding groove can be waist-shaped.

[0055] In some embodiments of this application, at least one support 121 is in the shape of a roller, which applies uniform pressure to the grass and helps to improve the grass collection effect of the grass collection device 100.

[0056] In some embodiments of this application, at least one support portion 121 has a first contact surface 1210 and a second contact surface 1211. The first contact surface 1210 is configured to contact the grass surface when moving in a first direction, and the second contact surface 1211 is configured to face the grass when moving in a second direction. The first contact surface 1210 is configured as an arc surface.

[0057] In some embodiments of this application, by configuring the first contact surface 1210 of the support portion as an arc surface, the support portion 121 generates sliding friction with the grass when the grass collecting device 100 moves forward, providing forward resistance. This allows the support component 12 to be better supported on the grass. On the one hand, it can raise the roller brush 110, reducing the resistance of the grass collecting device 100 and the pressure exerted by the roller brush 110 on the grass. This allows the grass clippings cut by the grass collecting device 100 to directly contact the roller brush 110, improving the grass collecting effect of the grass collecting device 100. On the other hand, it can prevent the middle part of the support component 12 from squeezing the grass, improving the grass collecting effect of the grass collecting device 100, while reducing the resistance of the grass collecting device 100.

[0058] In some embodiments of this application, the connecting part 120 and at least two supporting parts 121 are integrally formed structures, requiring only one set of molds for processing, which helps to reduce costs.

[0059] In some embodiments of this application, the connecting part 120 and at least two supporting parts 121 can be separately provided to facilitate the disassembly of the grass collecting device 100.

[0060] In some embodiments of this application, the support portion 121 may be eccentrically configured to reduce the resistance when the grass collecting device 100 moves in the second direction.

[0061] In some embodiments of this application, in the above-mentioned lawn mowing equipment 1, during the grass collection process of the grass collection device 100, by setting the length of the support component 12 along the moving direction of the main body 11 to be less than the length of the roller brush 110, the contact area between the support component 12 and the grass is reduced, the resistance of the grass roots to the support component 12 when the grass collection device 100 moves is reduced, and the grass collection device 100 can move smoothly, thereby improving the grass collection effect of the lawn mowing equipment.

[0062] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
