Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and in particular to a cutting mechanism and cutting equipment. Background Technology

[0002] As people's living standards continue to improve, they have increasingly higher requirements for their leisure environment. Private gardens, parks, playgrounds, and other similar venues have become the best places for people to relax and enjoy themselves. Currently, lawn mowing robots are commonly used to replace manual mowing, regularly maintaining the lawns of private gardens, parks, playgrounds, and other similar spaces to ensure their aesthetic appeal.

[0003] However, existing lawn mowers have blades of the same length and cutting width, which means that the blades are in contact with the cutting material across the entire cutting width at the same time. This increases the load on the drive motor, requiring a higher-performance drive motor, which in turn increases the size and cost of the lawn mower. Utility Model Content

The plane formed by the first mounting portion and the central axis of rotation of the mounting bracket is not coplanar with respect to the plane formed by the second mounting portion and the central axis of rotation of the mounting bracket. This allows the first and second cutting elements to have a phase difference when the mounting bracket rotates, thereby forming a staggered cutting trajectory. This ensures that the cutting force of the cutting mechanism is dispersed during cutting, avoiding the instantaneous high load caused by the first and second cutting elements contacting the workpiece simultaneously. The first cutting profile formed by the first cutting element and the second cutting profile formed by the second cutting element do not overlap at least partially, ensuring the continuity of the first and second cutting elements during cutting and reducing the contact area between the cutting mechanism and the workpiece simultaneously. This results in low resistance and low power consumption for the cutting mechanism, thereby reducing the load on the drive motor of the cutting mechanism and avoiding an increase in the external dimensions of the cutting mechanism due to an excessively large drive motor.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] It should also be understood that the terminology used in this application specification is merely for describing specific realities within the scope of this application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. 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 indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0052] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] like Figures 1 to 3 As shown, according to a first aspect of this application, this application provides a cutting mechanism 100, including a drive assembly 20 and a cutting assembly 10. The drive assembly 20 is pulsatorically connected to the cutting assembly 10 and is used to drive the cutting assembly 10 to rotate around a central axis to cut the object. The object to be cut includes, but is not limited to, grass on lawns, gardens, and paths; that is, the cutting mechanism 100 can cut grass on lawns to ensure the aesthetics of the lawn.

[0054] In one alternative implementation, such as Figure 4 , Figure 5 , Figures 7 to 9 As shown, the cutting assembly 10 includes a first cutting element 11, a second cutting element 12, and a mounting bracket 13 that can rotate around a central axis L. The mounting bracket 13 has a first mounting portion 1311 and a second mounting portion 1321 arranged along its outer circumference. The first cutting element 11 and the second cutting element 12 are respectively mounted on the first mounting portion 1311 and the second mounting portion 1321, so that the mounting bracket 13 can drive the first cutting element 11 and the second cutting element 12 to rotate around the central axis L to cut the object.

[0055] In one alternative implementation, such as Figure 5 , Figures 7 to 9As shown, the plane formed by the first mounting part 1311 and the central axis L is not coplanar with the plane formed by the second mounting part 1321 and the central axis L. This allows the first cutting element 11 and the second cutting element 12 to have a phase difference when the mounting bracket 13 rotates, thereby forming a staggered cutting trajectory. This ensures that the cutting force of the cutting mechanism 100 is dispersed during cutting, avoiding the instantaneous high load caused by the first cutting element 11 and the second cutting element 12 contacting the workpiece simultaneously. This achieves staggered operation of the first cutting element 11 and the second cutting element 12 in the time dimension. The first cutting profile formed by the first cutting element 11 when the mounting bracket 13 rotates and the second cutting profile formed by the second cutting element 12 when the second cutting element 12 rotates are at least partially non-overlapping. This ensures the continuity of the first cutting element 11 and the second cutting element 12 during cutting, reduces the contact area between the cutting mechanism 100 and the workpiece simultaneously, reduces resistance to the cutting mechanism 100, and minimizes power consumption. This reduces the load on the drive motor 21 of the cutting mechanism 100, avoiding an increase in the external dimensions of the cutting mechanism 100 due to an excessively large drive motor 21.

[0056] It should be noted that the first cutting profile and the second cutting profile formed by the first cutting member 11 and the second cutting member 12 during rotation only partially overlap or do not overlap at all. This can both expand the effective cutting area and reduce the mutual interference between the first cutting member 11 and the second cutting member 12. This application does not impose any limitations on this.

[0057] After adopting the above technical solution, since the first cutting part 11 and the second cutting part 12 are asymmetrically installed relative to the central axis L, and the first cutting profile and the second cutting profile formed by the two when the mounting bracket 13 rotates do not overlap at least partially, the phase difference between the first cutting part 11 and the second cutting part 12 on the mounting bracket 13 can be used to make the cutting profiles formed by the first cutting part 11 and the second cutting part 12 at least partially staggered, so as to avoid the cutting parts of the cutting mechanism 100 cutting the full width at the same time, optimize the load distribution of the cutting mechanism 100 during the cutting process, realize the staggered operation of the two cutting parts in the time dimension, so that a smaller size drive motor 21 can be selected, reducing the manufacturing cost of the cutting mechanism 100.

[0058] In one alternative implementation, such as Figures 4 to 6 As shown, the first cutting element 11 and the second cutting element 12 extend along the length direction of the central axis, and the first cutting element 11 and the second cutting element 12 do not overlap at least partially in the length direction, so that the first cutting element 11 and the second cutting element 12 can be distributed in a stepped manner along the length direction of the central axis L, reducing the contact area between the first cutting element 11 and the second cutting element 12 and the workpiece at the same time, realizing the staggered operation of the first cutting element 11 and the second cutting element 12 in the time dimension, so that the resistance they are subjected to is small, and reducing the energy consumption of the cutting mechanism 100 in the cutting process.

[0059] In one alternative implementation, such as Figures 4 to 6 As shown, the mounting bracket 13 includes a first tool holder 131 and a second tool holder 132. A first mounting portion 1311 is symmetrically arranged on both sides of the first tool holder 131, and a second mounting portion 1321 is symmetrically arranged on both sides of the second tool holder 132. The first tool holder 131 and the second tool holder 132 are arranged sequentially along the length of the central axis to form a spatially layered structure. The symmetrical arrangement of the first cutting element 11 and the second cutting element 12 ensures the dynamic balance of the cutting mechanism 100 during the cutting process, guarantees the dynamic balance of the mounting bracket 13 during rotation, and reduces vibration. It also enhances the cutting efficiency of the cutting assembly 10 and saves cutting time. Furthermore, this application separates the first tool holder 131 and the second tool holder 132, which not only facilitates the manufacturing of the mounting bracket 13 but also facilitates the assembly of the first cutting element 11 and the second cutting element 12.

[0060] In an optional embodiment, the first tool holder 131 and the second tool holder 132 are arranged perpendicularly to form an orthogonal layout so that the centrifugal forces of the first tool holder 131 and the second tool holder 132 can cancel each other out when rotating, thereby reducing vibration and improving the stability of the mounting bracket 13 at high speed.

[0061] In an optional embodiment, the cutting profile formed by the first cutting member 11 and the second cutting member 12 is rectangular in shape along the cross-sectional shape perpendicular to the central axis. That is, when the first cutting member 11 and the second cutting member 12 rotate, their blade tip trajectories form four sides on the axial projection, which together constitute a closed rectangle. This not only ensures the continuity of the first cutting member 11 and the second cutting member 12 in circumferential cutting, but also ensures the balanced distribution of the cutting force when the first cutting member 11 and the second cutting member 12 are cutting, avoiding significant sudden changes in the load of the drive motor 21, thereby shortening the service life of the drive assembly 20.

[0062] In an optional embodiment, the drive assembly 20 is connected to the mounting bracket 13 for driving the mounting bracket 13 to rotate the first cutting element 11 and the second cutting element 12 around the central axis L, so that the first cutting element 11 and the second cutting element 12 can perform cutting operations alternately, realizing the circumferential cutting motion of the first cutting element 11 and the second cutting element 12, which can ensure both the cutting width and the cutting effect of the cutting assembly 10.

[0063] In an optional embodiment, the drive assembly 20 includes a drive motor 21 and a transmission shaft 22. The drive motor 21 is provided with a drive shaft, and the transmission shaft 22 is disposed on one side of the drive motor 21 and is connected to the drive shaft for transmission. The mounting bracket 13 is connected to the transmission shaft 22 for transmission, providing a stable power foundation for the mounting bracket 13, so that the drive motor 21 can drive the mounting bracket 13 to rotate through the transmission shaft 22, thereby driving the first cutting piece 11 and the second cutting piece 12 on the mounting bracket 13 to rotate around the central axis L, thereby enabling the first cutting piece 11 and the second cutting piece 12 to perform cutting operations.

[0064] It should be noted that the drive shaft 22 can be integrated with the mounting bracket 13, and this application does not impose any restrictions on this.

[0065] In one alternative implementation, such as Figure 4 , Figures 7 to 8 As shown, the mounting bracket 13 has a through hole structure 13a at its center. The drive shaft 22 passes through the through hole structure 13a and is fixedly connected to the through hole structure 13a to achieve a stable connection between the drive shaft 22 and the mounting bracket 13, ensuring that the drive motor 21 can transmit torque to the mounting bracket 13 through the drive shaft 22.

[0066] In an optional embodiment, the drive shaft 22 is provided with a first axial section for transmitting torque, and the through-hole structure 13a is provided with a second axial section that mates with the first axial section. The second axial section is connected to the first axial section to ensure that torque is transmitted from the first axial section to the second axial section, thereby transmitting the drive torque to the mounting bracket 13. The shape of the first axial section includes, but is not limited to, a D-shape, a rhombus shape, a rectangle shape, or a spline shape, and the shape of the second axial section is adapted to the shape of the first axial section.

[0067] In an optional embodiment, the through-hole structure 13a includes a first through-hole 1312 formed on the first tool holder 131 and a second through-hole 1322 formed on the second tool holder 132. The first tool holder 131 is connected to the drive shaft 22 through the first through-hole 1312, and the second tool holder 132 is connected to the drive shaft 22 through the second through-hole 1322.

[0068] In an optional embodiment, the cutting mechanism 100 further includes a housing 30 and a protective cover 40. The housing 30 is installed outside the drive assembly 20, and the protective cover 40 is connected to the housing 30 and disposed outside the cutting assembly 10 to protect the drive assembly 20 and the cutting assembly 10, avoiding safety hazards caused by exposure of the drive assembly 20 and the cutting assembly 10, or direct contact with moisture in the air that would affect their service life, thereby improving safety in use. The protective cover 40 has an inlet for the material to be cut and an outlet for the material to be discharged, so that the material can enter the protective cover 40 from the inlet for cutting and the debris can be discharged from the outlet.

[0069] In an optional embodiment, the drive assembly 20 further includes a bearing 23. The drive shaft 22 of the drive assembly 20 passes through the through hole structure 13a of the mounting bracket 13. The bearing 23 is disposed at the connection between the drive shaft 22 and the cover 40 and is located on both sides of the mounting bracket 13 to ensure the smooth rotation of the drive shaft 22 relative to the cover 40.

[0070] In an optional embodiment, the cutting mechanism 100 further includes a fan 50, which is connected to the drive shaft 22 of the drive assembly 20 and is disposed inside the cover 40. The fan 50 can not only provide heat dissipation for the drive motor 21, but also blow the cut debris out of the cover 40 from the outlet.

[0071] In an optional embodiment, the first cutting member 11 includes a first blade 111 and a first fixing member 112. The first blade 111 is mounted on a plurality of first mounting portions 1311 along the symmetrical center of the mounting bracket 13 via the first fixing member 112, thereby achieving a fixed connection between the first blade 111 and the mounting bracket 13. The first fixing member 112 includes a first fixing plate and a first locking member. The first fixing plate has first fixing holes at both ends, and the first mounting portions 1311 have corresponding first screw holes. The first blade 111 is sandwiched between the first mounting portions 1311 and the first fixing plate. The first locking member passes through the first fixing hole and is threaded into the first screw hole, thereby fixing the first blade 111 onto the first mounting portion 1311.

[0072] In an optional embodiment, the second cutting member 12 includes a second blade 121 and a second fixing member 122. The second blade 121 is mounted on a plurality of second mounting portions 1321 symmetrically arranged around the mounting bracket 13 via the second fixing member 122, thereby achieving a fixed connection between the first blade 111 and the mounting bracket 13. The second fixing member 122 includes a second fixing plate and a second locking member. The second fixing plate has second fixing holes at both ends, and the second mounting portions 1321 have corresponding second screw holes. The second blade 121 is sandwiched between the second mounting portions 1321 and the second fixing plate. The second locking member passes through the second fixing hole and is threaded into the second screw hole, thereby fixing the second blade 121 onto the second mounting portion 1321.

[0073] In an optional embodiment, the first cutting member 11 further includes a first clamping member 113, which is disposed between the first fixing member 112 and the first blade 111, so that the first blade 111 can be tightly attached between the first mounting part 1311 and the first fixing member 112 to ensure the stability of the first blade 111 during the cutting process.

[0074] In an optional embodiment, the second cutting member 12 further includes a second clamping member 123 disposed between the second fixing member 122 and the second blade 121, so that the second blade 121 can be tightly attached between the second mounting portion 1321 and the second fixing member 122 to ensure the stability of the second blade 121 during the cutting process.

[0075] In one optional embodiment, the first clamping member 113 has a first contact portion, at least partially made of a deformable material, which contacts the first blade 111 to ensure the stability of the first blade 111 during the cutting process. The first contact portion includes, but is not limited to, silicone rubber.

[0076] In one optional embodiment, the second cutting member 12 has a second contact portion, at least partially made of a deformable material, which contacts the second blade 121 to ensure the stability of the second blade 121 during the cutting process. The second contact portion includes, but is not limited to, silicone rubber.

[0077] In an optional embodiment, the first clamping member 113 protrudes at least partially from the through hole of the first fixing member 112, and the second clamping member 123 protrudes at least partially from the through hole of the second fixing member 122, so that the stability of the first clamping member 113 and the second clamping member 123 can be checked by the first clamping member 113 and the second clamping member 123 protruding from the through holes of the first fixing member 112 and the second fixing member 122, thereby confirming whether the first blade 111 and the second blade 121 are installed stably.
