Description

Technical Field

[0001] The present application relates to the field of robot technology, and in particular to a grass collecting device and a grass mowing equipment. Background Art

[0002] The current mowing equipment cooperates with the roller brush and the roller so that the grass collecting device can collect fallen leaves and weeds on the grass. However, when the existing mowing equipment moves forward, the grass will exert a backward force on the roller, so that the roller can float normally, but the distance between the roller brush and the grass cannot be ensured, and the debris on the grass cannot be effectively collected. In addition, when the mowing equipment moves backward, the roller is easily affected by the grass on the grass, and the backward resistance is large, which makes it impossible to move smoothly. Summary of the invention

[0003] In view of this, the present application provides a grass collecting device and a grass mowing equipment that can effectively collect grass.

[0004] An embodiment of the present application provides a grass collecting device, comprising a main body and a support assembly. The main body comprises a roller brush. The support assembly is mounted on the main body and is located in front of the roller brush, and the support assembly is configured to be switchable between a first state and a second state to change the height of the roller brush. When the main body moves along a first direction, the support assembly is in the first state and lifts the roller brush to a first height. When the main body moves along a second direction, the support assembly switches from the first state to the second state, and the roller brush is at a second height, and the first height is greater than the second height.

[0005] In some embodiments of the present application, when the grass collecting device moves along a first direction, the support assembly is in a first state and lifts the roller brush to a first height, which can ensure 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 maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, and facilitating the effective collection of debris on the grass; and when the grass collecting device moves along a second direction, the support assembly switches from the first state to the second state, does not form resistance to the grass collecting device, reduces the resistance of the grass collecting device to move along the second direction, ensures that the grass collecting device can move smoothly along the second direction, and improves the grass collecting effect of the grass collecting device.

[0006] In some embodiments of the present application, the grass collecting device further includes a swinging member, a first end of the swinging member is connected to the supporting assembly, a second end of the swinging member is rotatably connected to the main body, and the swinging member can change the height of the roller brush during the swinging process.

[0007] In some embodiments of the present application, the height of the roller brush is changed by swinging the swing member. When the main body moves along the first direction, the height between the roller brush and the grass is ensured to be greater than the height between the support assembly and the grass, so that the roller brush maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, which is conducive to effectively collecting debris on the grass. When the main body moves along the second direction, the support assembly does not provide supporting force to the grass collecting device, so it does not form resistance to the grass collecting device, reducing the backward resistance of the grass collecting device, and ensuring that the grass collecting device can move backward smoothly.

[0008] In some embodiments of the present application, a connecting member is provided at the first end of the swinging member, and the connecting member is provided with a limiting portion. In the second state, the limiting portion abuts against the supporting assembly, which is beneficial to limit the rotation angle of the supporting assembly.

[0009] In some embodiments of the present application, the support assembly is provided with a protrusion, and the limiting portion is provided with a limiting groove cooperating with the protrusion. The protrusion extends into the limiting groove and can slide in the limiting groove. The two relative groove walls of the limiting groove limit the sliding of the protrusion within a preset range to limit the rotation of the support assembly within the preset range.

[0010] In some embodiments of the present application, by cooperating with the limiting groove and the protrusion, when the main body moves along the second direction, the rotation angle range of the support assembly is limited, and the movement range of the support assembly is accurately controlled, thereby preventing the support assembly from excessively rotating and causing the main body to be stuck when moving along the second direction, thereby ensuring that the grass collecting device can move smoothly.

[0011] In some embodiments of the present application, the swinging member includes an elastic member and a connecting member disposed at one end, the two ends of the elastic member are respectively disposed on the supporting assembly and the connecting member, and the elastic member is used to reset the supporting assembly.

[0012] In some embodiments of the present application, the automatic reset of the support assembly is achieved by the restoring force of the elastic member.

[0013] In some embodiments of the present application, the main body is provided with a blocking portion, and in the second state, the blocking portion abuts against the swinging member, and the swinging angle of the swinging member can be limited by the blocking portion.

[0014] In some embodiments of the present application, the support assembly includes a connecting portion and supporting portions located at two ends, and the connecting portion and the opposite side surfaces of the supporting portions located at two ends jointly form an air avoidance zone.

[0015] In some embodiments of the present application, an avoidance zone is set up so that the avoidance zone does not contact the grass, so that the avoided part of the grass is not squeezed, which can prevent the cut grass clippings from falling into the grass roots due to squeezing, making it difficult for the rear roller brush to collect the grass clippings. At the same time, the contact area between the grass and the support assembly can be reduced by setting the avoidance zone, which is beneficial to reducing 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.

[0016] In some embodiments of the present application, the connecting portion and the supporting portion are an integrally formed structure, which can be processed with only one set of molds, thereby helping to reduce costs.

[0017] In some embodiments of the present application, the width of the avoidance zone along a direction perpendicular to the moving direction of the main body along the first direction is greater than the width of the support portion along a direction perpendicular to the moving direction of the main body along the first direction, which is beneficial to reducing the resistance between the grass collecting device and the grass, thereby ensuring that the grass collecting device can move smoothly.

[0018] In some embodiments of the present application, the support portion has a working surface in contact with the grass, and the working surface is configured to slide in contact with the grass when moving along the first direction, which is beneficial to reducing the air resistance and friction resistance of the support portion when sliding on the grass, increasing the sliding speed of the support portion, and reducing the resistance of the grass collecting device.

[0019] In some embodiments of the present application, the support portion has a first contact surface and a second contact surface, the first contact surface is configured to contact the grass when moving along the first direction, the second contact surface is configured to face the grass when moving along the second direction, and the first contact surface is configured as an arc surface.

[0020] In some embodiments of the present application, by configuring the first contact surface of the support part as a curved surface, when the grass collecting device moves forward, on the one hand, the curved surface can reduce the air resistance and friction resistance when the support part slides on the grass, thereby increasing the sliding speed of the support part and reducing the resistance of the grass collecting device; on the other hand, the curved surface can disperse the pressure of the contact between the support part and the grass, enabling the grass clippings cut by the grass collecting device to directly contact the roller brush, thereby improving the grass collecting effect of the grass collecting device.

[0021] In some embodiments of the present application, the support portion is provided with a counterweight, and the counterweight is located on one side of the rotation axis of the support portion, which is conducive to achieving automatic resetting of the support portion.

[0022] In some embodiments of the present application, the grass collecting device also includes a slide member, a first end of the slide member is slidably connected to the support assembly, a second end of the slide member is connected to the main body via a rotating shaft, and the slide member rotates along the rotation direction of the rotating shaft so that the support assembly is configured to be switchable between a first state and a second state.

[0023] In some embodiments of the present application, in the first state, the support assembly is rotatable relative to the slide slot, which is beneficial for switching between the first state and the second state of the support assembly, thereby improving the grass collecting effect of the grass collecting device.

[0024] In some embodiments of the present application, the slide member is provided with a slide slot, and the two ends of the support assembly respectively pass through the slide slot and are slidably connected to the slide slot. In the first state, the support assembly can rotate relative to the slide slot, and the slide slot is helpful to limit the movement range of the support assembly.

[0025] In some embodiments of the present application, the support assembly includes at least one support portion, and at least one of the support portions is in a roller shape.

[0026] In some embodiments of the present application, a height of the center of gravity of the support assembly in the first state is smaller than a height of the center of gravity of the support assembly in the second state.

[0027] In some embodiments of the present application, the pressure exerted by the support assembly on the grass in the first state is greater than the pressure exerted by the support assembly on the grass in the second state.

[0028] An embodiment of the present application provides a grass collecting device, which includes: a main body, a support assembly and a swinging member. The main body includes a roller brush. The main body includes a roller brush. The support assembly is mounted on the main body and is located in front of the roller brush, and the support assembly is configured to be switchable between a first state and a second state. The first end of the swinging member is connected to the support assembly, and the second end of the swinging member is connected to the main body through a rotating shaft, and the swinging member is configured to swing along the rotation direction of the rotating shaft. When the main body moves along the first direction, the swinging member swings at a first swinging angle relative to the rotating shaft, and drives the support assembly to rotate relative to the swinging member, so that the support assembly is in the first state. When the main body moves along the second direction, the swinging member swings at a second swinging angle relative to the rotating shaft, and drives the support assembly to rotate relative to the swinging member, so that the support assembly is in the second state, and the first swinging angle is greater than the second swinging angle.

[0029] In some embodiments of the present application, when the grass collecting device moves along a first direction, the support assembly is driven to move by the slide member. When the support assembly is in a first state, the support assembly applies a first pressure to the grass and is supported on the grass to lift 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 maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, which is conducive to effectively collecting debris on the grass. When the grass collecting device moves along a second direction, the support assembly switches from the first state to the second state, the support assembly and the slide member move relative to each other, and the support assembly applies a second pressure to the grass. Since the support assembly moves in a direction away from the grass during the process of switching from the support assembly to the second state, it does not form resistance to the grass collecting device, thereby 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.

[0030] An embodiment of the present application provides a grass collecting device, which includes: a main body, a support assembly and a slide member. The main body includes a roller brush. The support assembly is mounted on the main body and is located in front of the roller brush, and the support assembly is configured to be switchable between a first state and a second state. The first end of the slide member is slidably connected to the support assembly, and the second end of the slide member is connected to the main body via a rotating shaft, and the slide member is configured to be able to drive the support assembly to move. When the main body moves along a first direction, the support assembly is in the first state and is configured to apply a first pressure to the grass. When the main body moves along the first direction, the support assembly switches from the first state to the second state, and the support assembly is configured to apply a second pressure to the grass.

[0031] In some embodiments of the present application, when the grass collecting device moves along a first direction, the support assembly is driven to move between a first position and a second position by a slide member. When the support assembly is in the first position, the support assembly applies a first pressure to the grass, and the support assembly is supported 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, so that the roller brush maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, which is conducive to effectively collecting debris on the grass, and when the grass collecting device retreats, the support assembly moves from the first position to the second position, and the second position is a position away from the grass. Therefore, the second pressure applied by the support assembly to the grass is very small or can be ignored, and no resistance is formed on the grass collecting device, thereby reducing the retreat resistance of the grass collecting device, ensuring that the grass collecting device can retreat smoothly, and improving the grass collecting effect of the grass collecting device.

[0032] In some embodiments of the present application, the slide member is provided with a slide slot, and both ends of the support component respectively pass through the slide slot and are slidably connected to the slide slot, and in the first state, the support component is rotatable relative to the slide slot.

[0033] In some embodiments of the present application, the support assembly includes at least one support portion, and at least one of the support portions is in a roller shape.

[0034] An embodiment of the present application further provides a lawn mowing device, comprising the above-mentioned grass collecting device.

[0035] In some embodiments of the present application, in the above-mentioned mowing equipment, when the grass collecting device moves along the first direction, it can ensure 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 maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, which is conducive to effectively collecting debris on the grass, and when the grass collecting device moves along the second direction, the resistance of the grass collecting device to move along the second direction can be reduced, ensuring that the grass collecting device can move smoothly along the second direction, thereby improving the grass collecting effect of the grass collecting device.

Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0051] It should be noted that when a component is referred to as being "disposed on" another component, it may be directly on the other component or there may be a component in the middle. The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0053] The current mowing equipment cooperates with the roller brush and the roller so that the grass collecting device can collect fallen leaves and weeds on the grass. However, when the existing mowing equipment moves forward, the grass will exert a backward force on the roller, so that the roller can float normally, but the distance between the roller brush and the grass cannot be ensured, and the debris on the grass cannot be effectively collected. In addition, when the mowing equipment moves backward, the roller is easily affected by the grass on the grass, and the backward resistance is large, which makes it impossible to move smoothly.

[0054] Therefore, in order to solve the above technical problems, some embodiments of the present application provide a grass collecting device. The grass collecting device includes a main body and a support assembly. The main body includes a roller brush. The support assembly is mounted on the main body and is located in front of the roller brush. The support assembly is configured to be switchable between a first state and a second state to change the height of the roller brush. When the main body moves along a first direction, the support assembly is in the first state and lifts the roller brush to a first height, 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 maintains a certain distance from the grass, reducing the resistance between the roller brush and the grass, and facilitating the effective collection of debris on the grass. When the main body moves along a second direction, the support assembly switches from the first state to the second state, does not form resistance to the grass collecting device, reduces the resistance of the grass collecting device to move along the second direction, ensures that the grass collecting device can move smoothly along the second direction, and improves the grass collecting effect of the grass collecting device.

[0055] The following is combined with Figures 1 to 8 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0056] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a lawn mowing device 1, wherein: Figure 1 X1 in the figure represents the moving direction of the mowing device 1 along the first direction, Figure 2 X2 in the figure represents the moving direction of the mowing device 1 along the second direction, Figure 1 and Figure 2 The A in refracted figure represents a lawn. The lawn mowing device 1 comprises a grass collecting device 100 .

[0057] like Figure 3 As shown, the grass collecting 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 mounted on the main body 11 and is located in front of the roller brush 110. The support assembly 12 is configured to be switchable between a first state and a second state to change the height of the roller brush 110. When the main body 11 moves along a first direction, the support assembly 12 is in the first state and lifts the roller brush 110 to be at a first height. When the main body 11 moves along a second direction, the support assembly 12 switches from the first state to the second state, and the roller brush 110 is at a second height. The first height is greater than the second height.

[0058] In some embodiments of the present application, when the grass collecting device 100 moves along the first direction, the support assembly 12 provides support force for the grass collecting device 100, the support assembly 12 is configured to be in the first state, and the roller brush 110 is raised to the first height. When the grass collecting device 100 moves along the second direction, the support assembly 12 does not provide support force for the grass collecting device 100, the support assembly 12 is configured to be in the second state, and the roller brush 110 is at the second height. Since in the second state, the roller brush 110 is only supported by the grass and not by the support force of the support assembly 12, the first height is greater than the second height.

[0059] In some embodiments of the present application, when the grass collecting device 100 moves along a first direction, the support assembly 12 is in a first state and lifts the roller brush 110 to a first height, which can ensure that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass, and when the grass collecting device 100 moves along a second direction, the support assembly 12 switches from the first state to the second state, does not form resistance to the grass collecting device 100, reduces the resistance of the grass collecting device 100 to move along the second direction, ensures that the grass collecting device 100 can move smoothly along the second direction, and improves the grass collecting effect of the grass collecting device 100.

[0060] In some embodiments of the present application, the height of the center of gravity of the support assembly 12 in the first state is smaller than the height of the center of gravity of the support assembly 12 in the second state.

[0061] In some embodiments of the present application, the center of gravity height is used to indicate the height of the center of gravity of the support assembly 12 relative to the grass. By setting the center of gravity height of the support assembly 12 in the first state to be less than the center of gravity height of the support assembly 12 in the second state, it is beneficial for the support assembly 12 to provide support force for the grass collecting device 100 in the first state to reduce the resistance between the roller brush 110 and the grass, and the support assembly 12 does not form resistance to the grass collecting device 100 in the second state to reduce the resistance of the grass collecting device 100 to move along the second direction, thereby improving the grass collecting effect of the grass collecting device 100.

[0062] In some embodiments of the present application, in the first state, the pressure exerted by the support component 12 on the grass is greater than the pressure exerted by the support component 12 on the grass in the second state, which is beneficial for the support component 12 to exert pressure on the grass in the first state to lift the roller brush 110, so that the roller brush 110 maintains a certain distance from the grass, reducing the resistance between the roller brush 110 and the grass, and is beneficial for effectively collecting debris on the grass. In the second state, the support component 12 may touch the grass to generate pressure, but the pressure does not form resistance to the grass collecting device 100, ensuring that the grass collecting device 100 can move smoothly along the second direction, thereby improving the grass collecting effect of the grass collecting device 100.

[0063] In some embodiments of the present application, refer to Figures 4 to 6 As shown, the grass collecting device 100 further includes a swinging member 13. A first end of the swinging member 13 is connected to the supporting assembly 12, and a second end of the swinging member 13 is rotatably connected to the main body 11. For example, the second end of the swinging member 13 can be rotatably connected to the main body 11 via a rotating shaft 14. The height of the roller brush 110 can be changed during the swinging process of the swinging member 13.

[0064] In some embodiments of the present application, during the swinging process of the swinging member 13 , the supporting assembly 12 may rotate or may not rotate, which is not limited in the present embodiment.

[0065] In some embodiments of the present application, when the grass collecting device 100 moves along the first direction, the grass applies a backward force to the roller brush 110, and the roller brush 110 can float normally. However, due to the weight of the roller brush 110 itself, the floating height of the roller brush 110 is limited. Therefore, during the swinging process of the swinging member 13, the support assembly 12 provides support force to the grass collecting device 100 and lifts the roller brush 110 to ensure that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass.

[0066] In some embodiments of the present 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, and the roller brush 110 may be inserted into the grass, which is not conducive to the retreat of the grass collecting device 100. Therefore, during the swinging process of the swinging member 13, the supporting assembly 12 does not provide supporting force to the grass collecting device 100, so no resistance is formed on the grass collecting device 100, thereby reducing the retreat resistance of the grass collecting device 100 and ensuring that the grass collecting device 100 can retreat smoothly.

[0067] In some embodiments of the present application, the main body 11 is provided with a blocking portion 111. In the second state, the blocking portion 111 abuts against the swinging member 13. The blocking portion 111 can limit the swinging angle of the swinging member 13.

[0068] In some embodiments of the present application, the swing member 13 includes an elastic member (not shown in the figure). Two ends of the elastic member are respectively arranged on the support assembly 12 and the connecting member 130. The elastic member is used to reset the support assembly 12.

[0069] In some embodiments of the present application, the elastic member is a torsion spring, which includes a first arm and a second arm, the first arm is connected to the support assembly 12, and the second arm is connected to the connecting member 130. When the grass collecting device 100 moves along the second direction and the support assembly 12 switches from the first state to the second state, when the support assembly 12 rotates relative to the connecting member 130, the torsion spring is torsionally deformed by an external force. When the grass collecting device 100 stops moving, the torsion spring generates a restoring force opposite to the external force, which is beneficial to utilizing the restoring force of the torsion spring to realize automatic resetting of the support assembly 12.

[0070] In some embodiments of the present application, see Figure 7 As shown, a connecting member 130 is provided at the first end of the swinging member 13. The connecting member 130 is provided with a limiting portion 1301, and in the second state, the limiting portion 1301 abuts against the supporting assembly 12.

[0071] In some embodiments of the present application, the limiting portion 1301 can abut against the support assembly 12 to limit the rotation angle of the support assembly 12. Specifically, the rotation angle of the support assembly 12 can be set according to the cross section of the support assembly 12. For example, if the cross section of the support assembly 12 is D-shaped, the rotation angle of the support assembly 12 can be set to 90 degrees.

[0072] In some embodiments of the present application, see 8 to Fig.10 As shown, the support assembly 12 is provided with a protrusion 123. The limiting portion 1301 is provided with a limiting groove 13011 that cooperates with the protrusion. The protrusion 123 extends into the limiting groove 13011 and can slide in the limiting groove 13011. The two opposite groove walls of the limiting groove 13011 limit the protrusion 123 to slide within a preset range, so as to limit the support assembly 12 from rotating within the preset range.

[0073] In some embodiments of the present application, by cooperating with the limiting groove 13011 and the protrusion 123, when the main body 11 moves along the second direction, the rotation angle range of the support assembly 12 is limited, and the movement range of the support assembly is accurately controlled, thereby preventing the support assembly 12 from excessively rotating and causing the main body 11 to be stuck when moving along the second direction, thereby ensuring that the grass collecting device 100 can move smoothly.

[0074] In some embodiments of the present application, the support assembly 12 includes a connection portion 120 and support portions 121 located at two ends. The connection portion 120 and the opposite sides of the support portions 121 located at two ends jointly form a clearance area 122 .

[0075] In some embodiments of the present application, a connecting portion 120 is provided between the supporting portions 121, and the connecting portion 120 maintains a certain height with the grass, so that an avoidance zone 122 is formed between the connecting portion 120 and the supporting portion 121. The avoidance zone 122 does not contact the grass, so that the avoided part of the grass is not squeezed, which can prevent the cut grass clippings from falling into the grass roots due to squeezing, making it difficult for the roller brush behind to collect the grass clippings. At the same time, by providing the avoidance zone 122, the contact area between the grass and the supporting assembly 12 can be reduced, which is beneficial to reducing 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.

[0076] In some embodiments of the present application, the number of support portions 121 may include 2, 3, 4, or more than 4, etc., which is not specifically limited herein.

[0077] In some embodiments of the present application, if the support portion 121 includes multiple support portions 121, the multiple support portions 121 are arranged sequentially on the connecting portion 120 along a direction perpendicular to the first direction, and the connecting portion 120 and the relative sides of any two adjacent support portions 121 together form a clearance zone.

[0078] In some embodiments of the present application, the avoidance zone 122 is at least partially located within the projection range of the roller brush 110 in a direction perpendicular to the main forward direction of the grass collecting device 100 , so that the cut grass clippings are not disturbed by the support assembly 12 and are smoothly collected by the roller brush 110 into the grass collecting device 100 .

[0079] In some embodiments of the present application, the connecting portion 120 and the supporting portion 121 are detachably connected, which is conducive to the rapid disassembly and assembly of the supporting portion 121, and is convenient for the maintenance and replacement of the supporting portion 121, thereby reducing the maintenance cost of the grass collecting device 100.

[0080] In some embodiments of the present application, the connecting portion 120 and the supporting portion 121 are integrally formed. By integrally forming the connecting portion 120 and the supporting portion 121, only one set of molds is required, which is conducive to reducing costs.

[0081] In some embodiments of the present application, the width of the avoidance area 122 along the direction perpendicular to the movement direction of the main body 11 along the first direction is greater than the width of the support portion 121 along the direction perpendicular to the movement direction of the main body 11 along the first direction, which is beneficial to reduce the resistance between the grass collecting device 100 and the grass, thereby ensuring that the grass collecting device 100 can move smoothly.

[0082] In some embodiments of the present application, the support portion 121 has a working surface 1210 in contact with grass. The working surface 1212 is configured to be in sliding contact with grass when moving along the first direction.

[0083] In some embodiments of the present application, the support portion 121 has a first contact surface 1211 and a second contact surface 1212, the first contact surface 1211 is configured to contact the grass when moving along the first direction, and the second contact surface 1212 is configured to face the grass when moving along the second direction, and the first contact surface 1211 is configured as an arc surface.

[0084] In some embodiments of the present application, by configuring the first contact surface 1210 of the support portion 121 as a curved surface, when the grass collecting device 100 moves forward, on the one hand, the curved surface can reduce the air resistance and friction resistance when the support portion 121 slides on the grass, thereby increasing the sliding speed of the support portion 121 and reducing the resistance of the grass collecting device 100; on the other hand, the curved surface can disperse the contact pressure between the support portion 121 and the grass, thereby enabling the grass clippings cut by the grass collecting device 100 to directly contact the roller brush 110, thereby improving the grass collecting effect of the grass collecting device 100.

[0085] In some embodiments of the present application, by configuring the second contact surface 1212 to face the grass when moving along the second direction, when the grass collecting device 100 moves along the second direction, the second contact surface 1212 may contact the grass, but the support assembly 12 does not provide a supporting force, so it does not form resistance to the grass collecting device 100. Therefore, the resistance of the grass collecting device 100 to move along the second direction is reduced, ensuring that the grass collecting device 100 can move smoothly along the second direction.

[0086] In some embodiments of the present application, the support assembly 12 includes at least one support portion 121 , and the at least one support portion 121 is in a drum shape.

[0087] In some embodiments of the present application, multiple support parts 121 can provide multiple support forces for the roller brush 110, which is conducive to better enabling the roller brush 110 to float upward, ensuring that the height of the support component 12 from the grass is less than the height of the roller brush 110 from the grass, so that the roller brush 110 maintains a certain distance from the grass, enabling the roller brush 110 to better collect debris on the grass, thereby improving the grass collecting effect of the grass collecting device 100.

[0088] In some embodiments of the present application, the support portion 121 is provided with a counterweight (not shown in the figure). The counterweight is located on one side of the rotation axis of the support portion 121. Figure 7As shown, O represents the rotation axis of the support part 121. When the main body moves along the first direction, the support part 121 is in a first state, the support part 121 is supported on the grass, and the counterweight is arranged on the side of the support part close to the grass, so that the weight of the side of the support part 121 with the counterweight is greater than the weight of the side of the support part 121 without the counterweight 1213. When the main body stops moving, the gravity of the side of the support part 121 with the counterweight 121 can be used to realize automatic resetting of the support part 121.

[0089] In some embodiments of the present application, the counterweight is detachably connected to the support portion 121 , which is beneficial for disassembling and assembling the counterweight, facilitating adjustment or maintenance of the counterweight, and ensuring the automatic resetting effect of the support portion 121 .

[0090] In some embodiments of the present application, the installation position of the counterweight and the support portion 121 can be adjusted by means of bolts, sliders, etc. to ensure that the gravity on the side of the support portion 121 where the counterweight is provided can achieve automatic resetting of the support portion 121.

[0091] In some embodiments of the present application, the configuration member is integrated with the support portion 121 , which is beneficial to reducing the number of parts of the grass collecting device and improving assembly efficiency.

[0092] In some embodiments of the present application, the support portion 121 includes a first portion 1213 and a second portion 1214 sequentially arranged along the rotation direction of the support portion 121 (such as the X direction in the figure), wherein the density of the first portion 1213 is greater than the density of the second portion 1214. Specifically, in the first state, when the main body moves along the first direction, the support portion 121 is in the first state, the first portion 1213 is supported on the grass, and when the main body stops moving, the gravity of the first portion 1213 can be used to achieve automatic reset of the support portion 121.

[0093] In some embodiments of the present application, the grass collecting device 100 further includes a slide member 15. A first end of the slide member 15 is slidably connected to the support assembly 12. A second end of the slide member 15 is connected to the main body 11 via a rotating shaft 14. The slide member 15 rotates along the rotation direction of the rotating shaft 14 so that the support assembly 12 is configured to switch between the first state and the second state.

[0094] In some embodiments of the present application, the slide member 15 is provided with a slide 150. Both ends of the support assembly 12 respectively pass through the slide 150 and are slidably connected with the slide 150. The slide 150 can limit the sliding distance of the support assembly 12. In the first state, the support assembly 12 can rotate relative to the slide 150. The slide 150 is conducive to limiting the movement range of the support assembly. For example, the slide can be waist-shaped.

[0095] In some embodiments of the present application, in the first state, the support assembly 12 is rotatable relative to the slide slot 150 , which is beneficial for switching between the first state and the second state of the support assembly 12 , thereby improving the grass collecting effect of the grass collecting device 100 .

[0096] In some embodiments of the present application, by driving the support assembly 12 to move when the slide member 15 rotates along the rotation direction of the rotating shaft 14, the position change between the support assembly 12 and the grass can be achieved. The greater the distance between the support assembly 12 and the grass, the smaller the pressure applied by the support assembly to the grass, thereby reducing the resistance to the grass collecting device, ensuring that the grass collecting device 100 can move smoothly, and thereby improving the grass collecting efficiency of the grass collecting device 100.

[0097] like Figures 3 to 5 As shown, a grass collecting device 100 is provided in one embodiment of the present application. The grass collecting device 100 includes a main body 11, a support assembly 12 and a swinging member 13. The main body 11 includes a roller brush 110. The support assembly 12 is mounted on the main body 11 and is located in front of the roller brush 110. The support assembly 12 is configured to be switchable between a first state and a second state. The first end of the swinging member 13 is connected to the support assembly 12, and the second end of the swinging member 13 is connected to the main body 11 through a rotating shaft 14. The swinging member 13 is configured to be able to drive the support assembly 12 to swing along the rotation direction of the rotating shaft 14. When the main body 11 moves along the first direction, the support assembly 12 is in the first state and swings at a first swing angle relative to the rotating shaft 14. When the main body 11 moves along the second direction, the support assembly 12 is in the second state and swings at a second swing angle relative to the rotating shaft 14. The first swing angle is greater than the second swing angle.

[0098] In some embodiments of the present application, when the grass collecting device 100 moves along the first direction, the grass applies a backward force to the roller brush 110, and the roller brush 110 can float normally. However, due to the weight of the roller brush 110 itself, the floating height of the roller brush 110 is limited. Therefore, the swing member 13 is swung at a first swing angle, and the support assembly 12 is driven to rotate, so that the support assembly 12 provides support force for the grass collecting device, and further lifts the roller brush 110 to ensure that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass.

[0099] In some embodiments of the present 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, and the roller brush 110 may be inserted into the grass, which is not conducive to the retreat of the grass collecting device 100. Therefore, the swing member 13 is swung at a second swing angle, and the support assembly 12 is driven to rotate, so that the support assembly 12 does not provide supporting force to the grass collecting device 100, and thus does not form resistance to the grass collecting device 100, thereby reducing the retreat resistance of the grass collecting device 100, ensuring that the grass collecting device 100 can retreat smoothly, and improving the grass collecting effect of the grass collecting device 100.

[0100] In some embodiments of the present application, see Figure 4 and Figure 5 As shown in the figure, O1 represents the center of the rotating shaft 14, α represents the first swing angle, and β represents the second swing angle.

[0101] In some embodiments of the present application, a connecting member 130 is provided at the first end of the swinging member 13. The connecting member 130 is provided with a limiting portion 1301, and in the second state, the limiting portion 1301 abuts against the supporting member assembly 12.

[0102] In some embodiments of the present application, the support assembly 12 is provided with a protrusion 123. The limiting portion 1301 is provided with a limiting groove 13011 that cooperates with the protrusion. The protrusion 123 extends into the limiting groove 13011 and can slide in the limiting groove 13011. The two opposite groove walls of the limiting groove 13011 limit the protrusion 123 to slide within a preset range, so as to limit the support assembly 12 from rotating within the preset range.

[0103] In some embodiments of the present application, the swing member 13 includes an elastic member 131. Two ends of the elastic member 131 are respectively disposed on the support assembly 12 and the connecting member 130. The elastic member 130 is used to reset the support assembly 12.

[0104] In some embodiments of the present application, the main body 11 is provided with a blocking portion 111. In the second state, the blocking portion 111 abuts against the swinging member 13, and the swinging angle of the swinging member 13 can be limited by the blocking portion 111.

[0105] See also Fig.11 and Fig.12As shown, in one embodiment of the present application, a grass collecting device 100 is provided, and the grass collecting device 100 includes a main body 11, a support assembly 12 and a slide member 15. The main body 11 includes a roller brush 110. The support assembly 12 is mounted on the main body 11 and is located in front of the roller brush 110. The support assembly 12 is configured to be able to switch between a first state and a second state. The first end of the slide member 15 is slidably connected to the support assembly 12, and the second end of the slide member 15 is connected to the main body 11 through a rotating shaft 14. The slide member 15 is configured to be able to drive the support assembly 12 to move. When the main body 11 moves along the first direction, the support assembly 12 is in the first state and is configured to apply a first pressure to the grass. When the main body 11 moves along the second direction, the support assembly 12 switches from the first state to the second state, and the support assembly 12 is configured to apply a second pressure to the grass. The first pressure is greater than the second pressure.

[0106] In some embodiments of the present application, when the grass collecting device 100 moves along the first direction, the support assembly 12 is driven to move by the slide member 15. When the support assembly 12 is in the first state, the support assembly 12 applies a first pressure to the grass, and is supported on the grass to lift the roller brush 110, ensuring that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass, and when the grass collecting device 100 moves along the second direction, the support assembly 12 switches from the first state to the second state, the support assembly 12 and the slide member move relative to each other, and the support assembly 12 applies a second pressure to the grass. Since the support assembly 12 moves in a direction away from the grass during the process of switching to the second state, the support assembly 12 moves in a direction away from the grass, so no resistance is formed on the grass collecting device 100, thereby reducing the resistance of the grass collecting device 100 to move 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.

[0107] In some embodiments of the present application, the slide member 15 is provided with a slide 150, and both ends of the support assembly 12 respectively pass through the slide 150 and are slidably connected with the slide 150. The slide 150 can limit the sliding distance of the support assembly 12. In the first state, the support assembly is rotatable relative to the slide, which is conducive to the mutual switching between the first state and the second state of the support assembly 12, thereby improving the grass collecting effect of the grass collecting device 100. In some embodiments of the present application, the support assembly 12 includes at least one support portion 121, and at least one support portion 121 is in the shape of a roller.

[0108] In some embodiments of the present application, multiple support parts 121 can provide multiple support forces for the roller brush 110, which is conducive to better enabling the roller brush 110 to float upward, ensuring that the height of the support component 12 from the grass is less than the height of the roller brush 110 from the grass, so that the roller brush 110 maintains a certain distance from the grass, enabling the roller brush 110 to better collect debris on the grass, thereby improving the grass collecting effect of the grass collecting device 100.

[0109] In one embodiment of the present application, a grass collecting device 100 is provided, and the grass collecting device 100 includes a main body 11, a support assembly 12 and a slide member 15. The main body 11 includes a roller brush 110. The support assembly 12 is mounted on the main body 11 and is located in front of the roller brush 110. The support assembly 12 is configured to be able to switch between a first state and a second state. The first end of the slide member 15 is slidably connected to the support assembly 12, and the second end of the slide member 15 is connected to the main body 11 through a rotating shaft 14. The slide member 15 is configured to be able to drive the support assembly 12 to move between a first position and a second position. When the main body 11 moves along the first direction, the support assembly 12 is in the first state and is located at the first position. When the main body 11 moves along the second direction, the support assembly 12 switches from the first state to the second state, and the support assembly 12 slides to the second position. The second position is higher than the first position.

[0110] In some embodiments of the present application, when the grass collecting device 100 moves along the first direction, the support assembly 12 is driven to move between the first position and the second position by the slide member 15. When the support assembly 12 is in the first position, the support assembly 12 applies a first pressure to the grass, and the support assembly 12 is supported on the grass, ensuring that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass, and when the grass collecting device 100 retreats, the support assembly 12 moves from the first position to the second position, and the second position is a position far away from the grass. Therefore, the second pressure applied by the support assembly to the grass is very small or can be ignored, and no resistance is formed on the grass collecting device 100, thereby reducing the retreat resistance of the grass collecting device 100, ensuring that the grass collecting device 100 can retreat smoothly, and improving the grass collecting effect of the grass collecting device 100.

[0111] In some embodiments of the present application, in the above-mentioned mowing equipment 1, when the grass collecting device 100 moves along the first direction, the support assembly 12 is in the first state and lifts the roller brush 110 to be at a first height, which can ensure that the height between the roller brush 110 and the grass is greater than the height between the support assembly 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 conducive to effectively collecting debris on the grass, and when the grass collecting device 100 moves along the second direction, the support assembly 12 switches from the first state to the second state, does not form resistance to the grass collecting device 100, reduces the resistance of the grass collecting device 100 to move along the second direction, ensures that the grass collecting device 100 can move smoothly along the second direction, and improves the grass collecting effect of the grass collecting device 100.

[0112] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as limitations on the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
