Description

Technical Field

[0001] This application relates to the field of grassland operation technology, and more particularly to a grass-cutting device. Background Technology

[0002] With the popularization of intelligent mobile robot technology, mobile devices with path planning functions, such as lawnmower robots that automatically extend ropes to mow lawns, are gradually replacing traditional manual lawn maintenance. Existing lawnmower robots have blades that directly contact the material being cut, lacking protective guards. This makes them prone to hitting protruding branches, stones, and other hard objects in the work environment, causing damage to the blades. Furthermore, the drive mechanism that provides rotational momentum to the blades is easily affected by external environmental interference, ultimately leading to decreased power transmission efficiency and impacting the normal operation of the lawnmower. Utility Model Content

[0003] This application provides a lawn mowing device. By incorporating a rigid connector integrally formed with the cutting component, and connecting the rigid connector to the output component of the drive component, the cutting component can efficiently receive the power output from the drive component while being protected by the protective component, thus ensuring the normal operation of the lawn mowing device.

[0004] In a first aspect, embodiments of this application propose a lawn mowing device, including a cutting component, a driving component, a rigid connector, and a protective component. The cutting component is used to operate on the lawn, the output component of the driving component is used to drive the cutting component to rotate, the rigid connector is connected to the output component, the rigid connector is integrally formed with the cutting component, and the protective component is located on the side of the cutting component away from the driving component. Part of the protective component is connected to the rigid connector, and another part of the protective component remains relatively stationary with the housing of the driving component.

[0005] This application incorporates a rigid connector integrally formed with the cutting component within the lawn mowing equipment. This rigid connector connects to the output component of the drive assembly. The rigid connector provides core strength, rigidity, and a precise center of rotation, bearing the main torque, bending moment, and impact forces. Furthermore, the cutting component and the rigid connector are integrally formed, forming a robust connection through mechanical interlocking and thermal stress bonding, which reduces the risk of loosening and failure during long-term use. In addition, by placing a protective component between the cutting component and the lawn to be mowed, the normal operation of the lawn mowing equipment can be ensured while extending its service life.

[0006] In one possible implementation, the rigid connector includes a first connecting part and a second connecting part. The first connecting part is detachably connected to the output component, and the second connecting part is detachably connected to a portion of the protective component. This allows the cutting component and the drive component to be separated from each other, as well as the cutting component and the protective component to be separated from each other. This facilitates the disassembly, assembly, and maintenance of the lawn mowing equipment, ensuring its working efficiency and service life.

[0007] In one possible implementation, the first connecting portion has a first groove, and the output component includes an output shaft and an assembly, with the assembly sleeved on the output shaft and nested in the first groove. This embodiment of the application, by nesting the assembly with the first groove, enables the output momentum of the drive component to be efficiently transferred to the rigid connecting component, which is beneficial for improving the working efficiency of the lawnmower.

[0008] In one possible implementation, the lawn mowing device further includes a fastener. The first connecting part includes a protrusion and a first fixing hole. The output part includes an output shaft and a fixing member. The fixing member is sleeved on the output shaft and has a second groove and a second fixing hole. The protrusion extends into the second groove, and the fastener is threadedly connected to the first fixing hole and the second fixing hole. The mating structure between the fixing member sleeved on the output shaft of the drive component and the first connecting part facilitates the efficient transmission of the output momentum of the drive component to the rigid connecting member, thereby efficiently driving the cutting component to rotate, which helps to improve the working efficiency of the lawn mowing device.

[0009] In one possible implementation, the fixing member is provided with a third groove, and the number of the second groove, the second fixing hole, and the third groove are all at least two, with the at least two second grooves, at least two second fixing holes, and at least two third grooves evenly distributed along the circumference of the fixing member. The third groove can be used to reduce the weight of the fixing member, so that less of the output momentum of the drive component is consumed by the fixing member, while more of the output momentum can be utilized by the integrated structure of the rigid connector and the cutting component, which is beneficial to improving the working efficiency of the lawn mowing equipment. The even distribution of the second groove, the second fixing hole, and the third groove can avoid the generation of polarization, which is beneficial to ensuring the normal operation of the lawn mowing equipment.

[0010] In one possible implementation, the fastener seals the side of the first connecting part that faces away from the protective component. This allows the fastener to isolate the rigid connecting part from the external environment, preventing hard objects such as protruding branches and stones in the work environment from directly impacting the rigid connecting part, and preventing weeds from entering the rigid connecting part and causing it to get stuck. Both of these measures help extend the service life of the lawnmower.

[0011] In one possible implementation, the protective assembly includes a baffle, a bracket, and a bearing. The baffle is detachably connected to the bracket, the outer ring of the bearing is connected to the inner wall of the bracket, and the inner ring of the bearing is connected to a second connecting part. Relative rotation can occur between the outer and inner rings of the bearing. Therefore, the outer ring of the bearing, the bracket, and the baffle can remain relatively stationary with respect to the housing of the drive assembly; that is, the outer ring of the bearing, the bracket, and the baffle do not rotate with the rigid connecting parts. By preventing the baffle from rotating during the operation of the lawnmower, it helps absorb the external potential energy from impacts from hard objects, ultimately reducing damage to other components of the lawnmower, such as the cutting assembly, the rigid connecting parts, and the drive assembly.

[0012] In one possible implementation, the ratio of the bearing's axial length along the second connection to the shaft diameter of the second connection is 1-2. This allows the bearing to stably withstand the enormous radial force and overturning moment caused by cutting resistance and foreign object impact, which helps ensure the normal operation of the mowing equipment. Furthermore, this ensures a uniform load distribution within the bearing, avoiding stress concentration and preventing premature bearing failure.

[0013] In one possible implementation, the cutting assembly includes a cutter head, blades, and a rigid connector. The rigid connector, cutter head, and rigid connector are integrally formed, and the rigid connector is used to assemble the blades onto the cutter head. The alternating load during blade cutting of lawn will cause stress concentration at the rigid connector. If the rigid connector is not rigid enough, it will deform, leading to blade loosening. Therefore, the rigid connector helps ensure the normal cutting operation of the blades. Furthermore, by making the rigid connector, cutter head, and rigid connector integrally formed, the risk of loosening and failure among these components during long-term use can be reduced.

[0014] In one possible implementation, a rigid connector is positioned in the central hole of the cutting assembly, which is symmetrical about the axis of the output component. This avoids vibrations caused by uneven mass distribution in the mating structure between the rigid connector and the output shaft. Furthermore, by aligning the rotation center of the rigid connector with its center of mass and geometric center, it prevents the rigid connector from generating harmful additional bending moments on the output component of the drive assembly, ultimately extending the service life of the lawnmower.

[0034] With the popularization of intelligent mobile robot technology, mobile devices with path planning functions, such as lawnmower robots that automatically extend ropes to mow lawns, are gradually replacing traditional manual lawn maintenance. Existing lawnmower robots have blades that directly contact the material being cut, lacking protective guards. This makes them prone to hitting protruding branches, stones, and other hard objects in the work environment, causing damage to the blades. Furthermore, the drive mechanism that provides rotational momentum to the blades is easily affected by external environmental interference, ultimately leading to decreased power transmission efficiency and impacting the normal operation of the lawnmower.

[0035] This application provides a lawn mowing device. By incorporating a rigid connector integrally formed with the cutting component, and connecting the rigid connector to the output component of the drive component, the cutting component can efficiently receive the power output from the drive component while being protected by the protective component, thus ensuring the normal operation of the lawn mowing device.

[0036] Figure 1 This is a schematic diagram of the structure of the lawn mowing device 1000 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the structure of a lawnmower 1000 provided in another embodiment of this application. Figure 3 This is an exploded view of the lawn mowing device 1000 provided in the embodiments of this application. Figure 4 This is a cross-sectional structural schematic diagram of the lawn mowing device 1000 provided in the embodiments of this application, combined with... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lawn mowing device 1000 includes a cutting assembly 200, a drive assembly 100, a rigid connector 1, and a protective assembly 300. Schematic, the protective assembly 300, the cutting assembly 200, and the drive assembly 100 are arranged sequentially along a direction perpendicular to the lawn to be mowed. The cutting assembly 200 is used to operate on the lawn, for example, by trimming weeds using cutting blades 202. The drive assembly 100 can provide rotational power to the cutting assembly 200, enabling the cutting assembly 200 to efficiently mow the lawn. Schematic, the drive assembly 100 can be a drive motor, and the drive assembly 100 can include an output component 101, which can be connected to the rigid connector 1. The rigid connector 1 can be integrally formed with the cutting assembly 200, meaning that the rotational momentum of the output component 101 can be transmitted to the cutting assembly 200 through the rigid connector 1, i.e., the output component 101 of the drive assembly 100 can be used to drive the cutting assembly 200 to rotate. This embodiment of the application incorporates a rigid connector 1 integrally formed with the cutting component 200 in the lawn mowing device 1000. The rigid connector 1 is connected to the output component 101 of the drive component 100. The rigid connector 1 provides core strength, rigidity, and a precise center of rotation, enabling it to withstand major torque, bending moment, and impact forces. Furthermore, the cutting component 200 and the rigid connector 1 are integrally formed, and a strong connection is formed between them through mechanical interlocking and thermal stress bonding, reducing the risk of loosening and failure during long-term use. This improves the power transmission efficiency between the drive component 100 and the cutting component 200, thereby ensuring the normal operation of the lawn mowing device 1000.

[0037] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the protective component 300 is located on the side of the cutting component 200 away from the drive component 100, that is, the protective component 300 is positioned between the lawn to be cut and the cutting component 200. The protective component 300 can be used to prevent the cutting component 200 from directly contacting protruding branches, stones, or other hard objects during operation, thus preventing damage. Part of the protective component 300 is connected to the rigid connector 1, that is, part of the protective component 300 rotates with the rigid connector 1, while another part of the protective component 300 remains relatively stationary with the housing 1014 of the drive component 100, that is, the other part of the protective component 300 does not rotate with the output component 101 of the drive component 100 and the rigid connector 1. By ensuring that a portion of the protective component 300 remains stationary during the operation of the lawnmower 1000, while the other portion rotates together with the output component 101, the rigid connector 1, and the cutting component 200, the stationary portion of the protective component 300 absorbs the external potential energy from the impact of the hard object, thus reducing the damage to the cutting component 200. Furthermore, the rigid connector 1 indirectly assembles the protective component 300 into the cutting component 200 without requiring additional parts, resulting in a simple structure and reducing the manufacturing cost of the lawnmower 1000.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application incorporates a rigid connector 1 integrally formed with the cutting component 200 in the lawn mower 1000. The rigid connector 1 is connected to the output component 101 of the drive component 100. The rigid connector 1 can withstand the main torque, bending moment, and impact force. Furthermore, the integral formation of the cutting component 200 and the rigid connector 1 creates a robust connection, reducing the risk of loosening and failure of the mating structure of the drive component 100, the rigid connector 1, and the cutting component 200 during long-term use of the lawn mower 1000. In addition, by placing the protective component 300 between the cutting component 200 and the lawn to be mowed, the normal operation of the lawn mower 1000 can be ensured while extending the service life of the lawn mower 1000.

[0039] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in one possible implementation, the rigid connector 1 includes a first connecting portion 11 and a second connecting portion 12, which are integrally formed. The first connecting portion 11 is detachably connected to the output component 101, meaning that the rigid connector 1 and the cutting component 200 integrally formed with the rigid connector 1 can be detached from the output component 101 of the drive component 100, repaired, and then reassembled onto the output component 101. The second connecting portion 12 is detachably connected to a partial protective component 300, meaning that the rigid connector 1 and the cutting component 200 integrally formed with the rigid connector 1 can be detached from the rotating partial protective component 300, and the protective component 300 can be cleaned and maintained before being reassembled onto the second connecting portion 12 of the rigid connector 1. This allows the cutting component 200 to be separated from the drive component 100, and the cutting component 200 to be separated from the protective component 300, which facilitates the disassembly, assembly, and maintenance of the lawn mowing equipment 1000, ensuring the working efficiency and service life of the lawn mowing equipment 1000.

[0040] Combination Figure 1 , Figure 3 and Figure 4 As shown, in one possible implementation, the protective component 300 may include a baffle 301, a bracket 302, and a bearing 303. The baffle 301 is detachably connected to the bracket 302. The baffle 301 can be used to isolate the area of ​​the cutting component 200 other than the part that directly cuts the lawn, so as to prevent protruding branches, stones, and other hard objects in the working environment from directly hitting the non-working parts of the cutting component 200. The bearing 303 can be nested in the central channel of the bracket 302, that is, the outer ring 3032 of the bearing 303 can be connected to the inner wall of the bracket 302. The inner ring 3031 of the bearing 303 can be connected to the second connecting part 12, that is, the inner ring 3031 of the bearing 303 can rotate together with the rigid connecting member 1 under the drive of the output shaft 1011 of the drive component 100. The outer ring 3032 and the inner ring 3031 of the bearing 303 can rotate relative to each other. Therefore, the outer ring 3032, the bracket 302, and the baffle 301 of the bearing 303 can remain relatively stationary with respect to the housing 1014 of the drive assembly 100. That is, the outer ring 3032, the bracket 302, and the baffle 301 of the bearing 303 do not rotate with the rigid connecting member 1. By preventing the baffle 301 from rotating during the operation of the lawn mower 1000, it is beneficial for the baffle 301 to absorb the external potential energy brought by the impact of hard objects, ultimately reducing the damage to other components of the lawn mower 1000, such as the cutting assembly 200, the rigid connecting member 1, and the drive assembly 100.

[0041] Combination Figure 1 , Figure 3 and Figure 4As shown, in one possible implementation, the ratio of the axial length of the bearing 303 along the second connecting portion 12 to the shaft diameter of the second connecting portion 12 can be 1-2. For example, the ratio of the axial length of the bearing 303 along the second connecting portion 12 to the shaft diameter of the second connecting portion 12 can be any value such as 1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2, as long as the ratio of the axial length of the bearing 303 along the second connecting portion 12 to the shaft diameter of the second connecting portion 12 is 1-2. By making the ratio of the axial length of the bearing 303 along the second connecting portion 12 to the shaft diameter of the second connecting portion 12 1-2, the bearing 303 can stably withstand the huge radial force and overturning moment brought about by cutting resistance and foreign object impact, which is beneficial to ensuring the normal operation of the mowing equipment 1000. In addition, this allows for a uniform load distribution inside bearing 303, avoiding stress concentration and preventing premature failure of bearing 303.

[0042] Figure 5 This is a structural schematic diagram of the rigid connector 1 provided in the embodiments of this application, combined with... Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in one possible implementation, the first connecting portion 11 may have a first groove 111, the opening of which faces the output member 101 of the drive assembly 100. Schematic, the first groove 111 may be centrally located on the side of the first connecting portion 11 facing the drive assembly 100. The output member 101 may include an output shaft 1011 and a fitting 1012. Schematic, the output shaft 1011 may be the motor shaft of a drive motor. The fitting 1012 may be sleeved on the output shaft 1011. Specifically, the end of the output shaft 1011 adjacent to the first connecting portion 11 has a threaded structure, and the fitting 1012 may be a nut, threadedly connected to the output shaft 1011. The fitting 1012 may be nested within the first groove 111, i.e., the outer wall of the fitting 1012 contacts the inner wall of the first groove 111, and the inner wall of the fitting 1012 contacts the outer peripheral surface of the output shaft 1011. This embodiment of the application achieves efficient transmission of the output momentum of the drive component 100 to the rigid connector 1 by nesting the fitting 1012 with the first groove 111, thereby efficiently driving the cutting component 200 to rotate and improving the working efficiency of the lawn mowing equipment 1000. For example, the fitting 1012 can be a nut with a specific shape, such as a hexagonal nut, and the opening shape of the corresponding first groove 111 is a matching hexagon. This allows the opening of the first groove 111 to complement the fitting 1012. This application does not limit the shape of the fitting 1012 and the first groove 111, as long as the fitting 1012 can nest with the first groove 111.

[0043] Figure 6 This is a structural schematic diagram of the fastener 1013 provided in the embodiments of this application, combined with... Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one possible embodiment, the lawn mowing device 1000 may further include a fastener 400. The first connecting portion 11 includes a protrusion 112 and a first fixing hole 113. The protrusion 112 protrudes toward the drive assembly 100, and the first fixing hole 113 extends from the cutting assembly 200 toward the drive assembly 100. The output component 101 may include an output shaft 1011 and a fixing component 1013. The fixing component 1013 may be sleeved on the output shaft 1011. Specifically, the fixing component 1013 has a through hole 10134, into which the output shaft 1011 extends and can be threadedly connected. The fixing member 1013 has a second groove 10131 and a second fixing hole 10132. The opening of the second groove 10131 faces the first connecting part 11, and the protrusion 112 protrudes towards the fixing member 1013. The protrusion 112 extends into the second groove 10131, that is, the protrusion 112 abuts against the inner wall of the second groove 10131. This makes it possible for the second groove 10131 and the protrusion 112 to cooperate in positioning the fixing member 1013 on the rigid connecting member 1 when the output part 101 of the drive assembly 100 needs to be assembled to the first connecting part 11 of the rigid connecting member 1. This facilitates the quick placement of the drive assembly 100 in the connection position of the rigid connecting member 1. The extension direction of the second fixing hole 10132 is parallel to the axial direction of the output shaft 1011. When the fixing member 1013 is placed on the first connecting part 11 through the positioning action of the second groove 10131 and the protrusion 112, the first fixing hole 113 and the second fixing hole 10132 are connected. The fastener 400 can be threaded to the first fixing hole 113 and the second fixing hole 10132. That is, the fastener 400 passes through the first fixing hole 113 and the second fixing hole 10132 in sequence so that the fixing member 1013 can be detachably connected to the first connecting part 11. In this embodiment, the cooperation between the second groove 10131 and the protrusion 112 facilitates the quick placement of the drive assembly 100 at the connection position of the rigid connecting member 1. Combined with the fastener 400 being threaded to the first fixing hole 113 and the second fixing hole 10132 in sequence, the output member 101 is finally quickly assembled onto the rigid connecting member 1. Furthermore, the fitting structure between the fixing member 1013 sleeved on the output shaft 1011 of the drive assembly 100 and the first connecting part 11 is conducive to the efficient transmission of the output momentum of the drive assembly 100 to the rigid connecting member 1, thereby efficiently driving the cutting assembly 200 to rotate, which is beneficial to improving the working efficiency of the mowing equipment 1000.

[0044] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one possible implementation, the lawnmower 1000 may include a fastener 400, the first connecting portion 11 may include a protrusion 112, the first connecting portion 11 may have a first groove 111 and a first fixing hole 113, the output member 101 may include an output shaft 1011, a mounting part 1012, and a fixing member 1013, the mounting part 1012 may be nested in the first groove 111. The fixing member 1013 has a second groove 10131 and a second fixing hole 10132, the protrusion 112 extends into the second groove 10131, and the fastener 400 is threadedly connected to the first fixing hole 113 and the second fixing hole 10132. This application embodiment achieves nested engagement between the mounting part 1012 and the first groove 111 of the first connecting part 11, and detachable connection between the fixing part 1013 and the first connecting part 11, so that the output momentum of the driving component 100 can be transmitted to the rigid connecting part 1 through dual paths at the same time, thereby driving the cutting component 200 to rotate, which is beneficial to further improve the working efficiency of the mowing equipment 1000.

[0045] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one possible implementation, the output shaft 1011 may have a shoulder 10111. Schematally, with the shoulder 10111 as the boundary, the shaft diameter of the portion of the output shaft 1011 adjacent to the protective assembly 300 is smaller than the shaft diameter of the portion of the output shaft 1011 away from the protective assembly 300. The opening of the through hole 10134 of the fixing member 1013 is an irregularly shaped hole, distinct from a circular hole, and the projected shape of the through hole 10134 along the axial direction of the output shaft 1011 can match the aforementioned portion of the output shaft 1011 adjacent to the protective assembly 300. Specifically, the fixing member 1013 may be provided with a bearing portion 10135, and the output shaft 1011 may extend into the through hole 10134 until the shaft shoulder 10111 abuts against the bearing portion 10135. With the limiting effect of the mounting accessory 1012 on the output shaft 1011, the fixing member 1013 can be clamped and fixed by supporting forces in two opposite directions along the axial direction of the output shaft 1011. This ensures the stability of the mating structure between the fixing member 1013 and the output shaft 1011. Furthermore, through the abutment positioning of the shaft shoulder 10111 and the bearing portion 10135, and the limiting effect of the mounting accessory 1012 on the output shaft 1011, the output shaft 1011 can be freely rotated clockwise or counterclockwise while being fixed.

[0046] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one possible implementation, the fixing member 1013 is provided with a third groove 10133. The third groove 10133 can be used to reduce the weight of the fixing member 1013, so that the output momentum of the drive assembly 100 can be consumed less by the fixing member 1013, and the output momentum can be utilized more by the integrated structure of the rigid connector 1 and the cutting assembly 200, which is beneficial to improving the working efficiency of the lawn mowing equipment 1000.

[0047] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one possible implementation, the number of the second groove 10131, the second fixing hole 10132, and the third groove 10133 are all at least two, and the at least two second grooves 10131, at least two second fixing holes 10132, and at least two third grooves 10133 are evenly distributed along the circumference of the fastener 1013. Specifically, the second groove 10131, the second fixing hole 10132, and the third groove 10133 can be arranged alternately in a periodic manner. For example, along the circumference of the fastener 1013, one second groove 10131, one second fixing hole 10132, one third groove 10133, another second groove 10131, another second fixing hole 10132, and another third groove 10133 are arranged in sequence. That is, the second groove 10131, the second fixing hole 10132, and the third groove 10133 can be regarded as a unit combination structure, and at least two of the unit combination structures can be periodically and evenly distributed along the circumference of the fastener 1013. This allows the second groove 10131 of the fixing member 1013 to perform a positioning function, the second fixing hole 10132 to perform a connecting function, and the third groove 10133 to perform a weight reduction function. At the same time, the distribution of the three will not cause the center of gravity of the fixing member 1013 to deviate from the axis of the output shaft 1011 of the drive assembly 100, thereby avoiding polarization and ensuring the normal operation of the mowing equipment 1000.

[0048] Combination Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one possible implementation, the fixing member 1013 seals the side of the first connecting portion 11 facing away from the protective assembly 300. Specifically, when the fixing member 1013 forms a positioning engagement with the protrusion 112 of the first connecting portion 11 through the second groove 10131, the side of the fixing member 1013 facing the first connecting portion 11, that is, the side where the opening of the second groove 10131 is located, can completely cover the side of the first connecting portion 11 facing away from the protective assembly 300. This allows the fixing member 1013 to isolate the rigid connecting member 1 from the external environment, so as to prevent protruding branches, stones and other hard objects in the working environment from directly hitting the rigid connecting member 1, and to prevent weeds from entering the rigid connecting member 1 and causing weed jamming, both of which help to extend the service life of the lawn mowing equipment 1000.

[0049] Figure 7 This is a schematic diagram of the mating structure between the rigid connector 1 and the cutting assembly 200 provided in the embodiments of this application. Figure 8 This is a structural schematic diagram of a lawnmower 1000 without the protective component 300 provided in this application embodiment, combined with... Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in one possible implementation, the cutting assembly 200 may include a cutter head 201, blades 202, and a rigid connecting seat 203. The cutter head 201 can be used to mount the blades 202 and receive the rotational momentum transmitted from the drive assembly 100 through the rigid connecting member 1. The rigid connecting seat 203 can be used to assemble the blades 202 onto the cutter head 201. Schematic, the rigid connecting seat 203 can be a nut, and the blades 202 can be fixed to the rigid connecting seat 203 by threaded connection. There can be multiple blades 202, which can be evenly arranged circumferentially along the cutter head 201. The alternating load during blade cutting of lawn will cause stress concentration at the rigid connecting seat 203. If the rigid connecting seat 203 is not rigid enough, it will deform, causing the blades 202 to loosen. Therefore, the rigid connecting seat 203 helps to ensure the normal cutting operation of the blades 202. The rigid connecting seat 203, the cutter head 201 and the rigid connecting component 1 are integrally formed. The three are connected by mechanical interlocking and thermal stress to form a firm connection, which can reduce the risk of loosening and failure of the rigid connecting seat 203, the cutter head 201 and the rigid connecting component 1 during long-term use.

[0050] Combination Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, in one possible implementation, the rigid connector 1 is disposed in the central hole of the cutting assembly 200, and the central hole is symmetrical about the axis of the output member 101, that is, the axis of the second connecting portion 12 of the rigid connector 1 coincides with the axis of the output member 101. This can avoid vibration caused by uneven mass distribution of the mating structure between the rigid connector 1 and the output shaft 1011, and by aligning the rotation center of the rigid connector 1 with the center of mass and the geometric center, it avoids the rigid connector 1 generating harmful additional bending moment on the output member 101 of the drive assembly 100, ultimately helping to extend the service life of the lawnmower 100.
