[0047] like Figure 1 As shown, a blade disc mechanism 1000 is provided in the embodiment and can be applied to a lawn mower.

[0048] like Figures 1 to 3 As shown, the blade disc mechanism 1000 may include a base 100 , a driving unit 200 , a blade disc 300 , and a baffle 400 .

[0049] The base 100 is provided with a ground-closed side 101 . That is, during normal use of the lawn mower, the side of the base 100 facing the ground may be the ground-closed side 101 .

[0050] The drive unit 200 may be mounted on the base 100. The blade disc 300 may be disposed on the ground side 101 of the base 100. The blade disc 300 includes a blade disc frame 310 and a blade 320. The blade disc frame 310 is connected to the output shaft 211 of the drive unit 200, and the blade disc frame 310 may be fixed relative to the output shaft 211 of the drive unit 200. The blade 320 has a first end 321 and a second end 322, and the first end 321 may be connected to the blade disc frame 310. In some embodiments, the first end 321 may be connected to the edge of the blade disc frame 310. The second end 322 may be protruded relative to the peripheral side of the blade disc frame 310. During use, the drive unit 200 may drive the blade disc frame 310 to rotate, thereby driving the blade 320 to rotate to achieve a mowing action.

[0051] The baffle 400 is disposed on a side of the blade disc 300 away from the base 100 . The baffle 400 is rotatably connected to the output shaft 211 of the driving unit 200 , that is, the baffle 400 can rotate relative to the output shaft 211 of the driving unit 200 .

[0052] During the mowing process, the baffle 400 is stopped between the blade frame 310 and the grass, so that most of the grass cannot directly contact the blade frame 310, thereby reducing the probability of grass being entangled in the blade frame 310, and further reducing the possibility of problems such as overcurrent in the drive unit 200 due to increased load, thereby protecting the drive unit 200, extending the service life of the drive unit 200, and further extending the service life of the lawn mower.

[0053] like Figure 1 and Figure 3 As shown, in some embodiments, the drive unit 200 includes a drive member 210 and a housing assembly 220. The housing assembly 220 may include a housing 221 and an end cap 222. The end cap 222 may be connected to one end of the housing 221 by snap connection or screw connection, and cooperate with the housing 221 to form an assembly cavity 2201. One end of the housing 221 away from the end cap 222 may be inserted into the base 100 and exposed relative to the ground-proximal side 101 of the base 100.

[0054] In some embodiments, the housing assembly 220 may be fixedly connected to the base 100. Alternatively, the housing assembly 220 may be slidably mounted on the base 100, and the housing assembly 220 may be telescopically arranged relative to the ground side 101 of the base 100, so that the distance between the cutter head 300 and the ground can be adjusted.

[0055] like Figure 1 and Figure 3As shown, a sealing ring 570 may be provided at the connection position between the shell 221 and the base 100. The sealing ring 570 may be provided around the circumference of the shell 221. In the embodiment, the sealing ring 570 may be pressed against the ground-proximal side 101 of the base 100 by a pressing plate 580, and the pressing plate 580 may be fixedly connected to the ground-proximal side 101 of the base 100 by screw connection or clamping. In addition, the inner side of the sealing ring 570 may abut against the side of the shell 221 away from the assembly cavity 2201. Thus, the sealing of the connection position between the shell 221 and the base 100 can be achieved, the probability of grass clippings and the like entering the base 100 can be reduced, and at the same time, a waterproof effect can be achieved.

[0056] In some embodiments, the driving member 210 may use a motor. The output shaft 211 of the driving unit 200 may refer to the output shaft 211 of the driving member 210. The driving member 210 may be installed in the assembly cavity 2201, and the output shaft 211 of the driving member 210 may be arranged away from the end cover 222. In an embodiment, the output shaft 211 of the driving member 210 may be arranged through an end of the housing 221 away from the end cover 222, and protrude relative to the side of the housing 221 away from the assembly cavity 2201, that is, the output shaft 211 of the driving member 210 may extend to the outside of the housing assembly 220. Accordingly, the output shaft 211 of the driving member 210 may be arranged to protrude relative to the near-ground side 101 of the base 100.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments, the cutter head mechanism 1000 further includes a mounting seat 530. The mounting seat 530 can be fixedly connected to the output shaft 211 of the driving member 210 by screw connection, clamping or bonding. The mounting seat 530 can be coaxially arranged with the output shaft 211.

[0058] The blade holder 310 can be fixedly connected to the mounting seat 530 by screw connection or clamping, and the blade holder 310 can be located on the side of the mounting seat 530 away from the base 100. In the embodiment, the blade holder 310 can be coaxially arranged with the mounting seat 530, so as to avoid the shaking and other problems caused by the eccentricity of the blade holder 310, ensure the stability of the rotation of the blade holder 310 during use, reduce the vibration of the blade holder 300 during operation, and smoothly realize the mowing action to ensure the mowing efficiency.

[0059] like Figures 1 to 4As shown, in some embodiments, the blade disc 300 may include a plurality of blades 320, and the plurality of blades 320 may be arranged uniformly or non-uniformly around the circumference of the mounting seat 530. The first end 321 of the blade 320 may be connected to the edge of the blade disc frame 310 by screw connection or the like, and the second end 322 of the blade 320 may be arranged to protrude relative to the circumference of the blade disc frame 310, so that the second end 322 of the blade 320 may smoothly contact the grass to achieve a mowing action. In an embodiment, the blade tip of the blade 320 may be parallel to the radial direction of the blade disc frame 310, and the blade tip is provided on both sides of the blade 320. Thus, the mowing action can be achieved in the process of the blade disc 300 rotating counterclockwise or clockwise.

[0060] During mowing, the driving member 210 can drive the mounting seat 530 to rotate, and the mounting seat 530 drives the blade holder 310 to rotate, and then the blade holder 310 drives the blade 320 to rotate around the output shaft 211 of the driving member 210 to achieve mowing.

[0061] like Figure 3 and Figure 4 As shown, the cutter disc mechanism 1000 further includes a connecting shaft 510 and an adapter seat 520 .

[0062] The interior of the connecting shaft 510 is a hollow structure and presents a tubular structure. In some embodiments, the interior of the connecting shaft 510 may be embedded with a threaded sleeve 540 by pre-embedding or the like, and the threaded sleeve 540 may be fixed relative to the connecting shaft 510. The inner wall of the threaded sleeve 540 on the side away from the connecting shaft 510 is provided with an internal thread.

[0063] In some embodiments, the threaded sleeve 540 can be connected to the mounting seat 530 by means of screw connection or the like, and can be fixedly arranged relative to the mounting seat 530. Specifically, the screw can be sequentially passed through the mounting seat 530 and the threaded sleeve 540, and screwed with the threaded sleeve 540. The head of the screw can be limitedly abutted against the side of the mounting seat 530 away from the connecting shaft 510. Thus, the connecting shaft 510 and the threaded sleeve 540 can be fixedly connected, and then the connecting shaft 510 and the mounting seat 530 can be fixedly connected.

[0064] like Figure 3 and Figure 4 As shown, the adapter seat 520 can be rotatably installed on the peripheral side of the connecting shaft 510 through the bearing 550, and the adapter seat 520 can be located on the side of the blade holder 310 away from the base 100.

[0065] In some embodiments, a first assembly groove 511 may be configured on a side of the connecting shaft 510 away from the threaded sleeve 540. The first assembly groove 511 may be located at an end of the connecting shaft 510 away from the mounting seat 530, and the side of the first assembly groove 511 away from the mounting seat 530 is configured as an opening. The bearing 550 may be sleeved on the circumference of the connecting shaft 510 from the opening side of the first assembly groove 511, and the inner ring of the bearing 550 may be embedded in the first assembly groove 511.

[0066] In some embodiments, the cutter head mechanism 1000 further includes a first limit plate 561. The first limit plate 561 can be fixedly connected to the threaded sleeve 540 by screw connection, and the first limit plate 561 can abut against the threaded sleeve 540 and the side of the connecting shaft 510 away from the mounting seat 530. In addition, the peripheral side of the first limit plate 561 can protrude relative to the peripheral side of the connecting shaft 510 and be opposite to the side wall of the first assembly groove 511 close to one end of the mounting seat 530. Accordingly, the first limit plate 561 can abut against the side of the inner ring of the bearing 550 away from the mounting seat 530 to tighten the inner ring of the bearing 550 in the first assembly groove 511. Thereby, the inner ring of the bearing 550 can be fixedly arranged relative to the connecting shaft 510.

[0067] The adapter 520 may be sleeved on the side of the bearing 550 away from the connecting shaft 510, and the adapter 520 may be fixedly connected to the outer ring of the bearing 550. In some embodiments, the adapter 520 is provided with a second assembly groove 521 on the side facing the connecting shaft 510, and the side of the second assembly groove 521 away from the mounting seat 530 may be configured as an opening. The outer ring of the bearing 550 may be disposed in the second assembly groove 521.

[0068] In addition, the cutter disc mechanism 1000 further includes a second limit plate 562. The second limit plate 562 can be fixedly connected to the side of the adapter seat 520 away from the cutter disc 300 by means of screw connection or the like, and the second limit plate 562 can protrude relative to the adapter seat 520 toward the side of the connecting shaft 510. Accordingly, the second limit plate 562 can be opposite to the side wall of the second assembly groove 521 close to the mounting seat 530, and the second limit plate 562 abuts against the side of the outer ring of the bearing 550 away from the cutter disc 300, and can clamp and fix the outer ring of the bearing 550, so that the outer ring of the bearing 550 is fixed relative to the adapter seat 520. In this way, the adapter seat 520 can be rotatably mounted on the connecting shaft 510.

[0069] In the embodiment, the baffle 400 can be fixedly connected to the side of the adapter 520 away from the cutter head 300 by screw connection or clamping. In this way, the baffle 400 can be rotatably connected to the output shaft 211.

[0070] In other embodiments, the baffle 400 may also be sleeved on the peripheral side of the adapter 520 and fixedly connected to the adapter 520 , and the baffle 400 and the blade 320 are spaced apart.

[0071] In some embodiments, a first limiting flange 522 is protruded from one side of the adapter 520 toward the blade holder 310 . The first limiting flange 522 may be an annular structure and may be arranged along the edge of the adapter 520 . The first limiting flange 522 may be coaxial with the output shaft 211 .

[0072] The cutter head frame 310 is provided with two annular second limiting flanges 311 protruding from one side of the adapter 520. The two second limiting flanges 311 are arranged to be nested and spaced apart to form an annular first limiting groove 312. In the embodiment, the first limiting groove 312 can be arranged coaxially with the output shaft 211.

[0073] In some embodiments, the first limiting flange 522 can be movably inserted into the first limiting groove 312, that is, the first limiting flange 522 can move in the first limiting groove 312 and can rotate around the connecting shaft 510. In the embodiment, the first limiting flange 522 is spaced apart from the cutter head frame 310 on one side thereof. The first limiting flange 522 is spaced apart from the two second limiting flanges 311.

[0074] When the adapter seat 520 rotates relative to the connecting shaft 510, the first limiting flange 522 can cooperate with the first limiting groove 312 to provide a guiding and limiting function for the adapter seat 520, thereby reducing the probability of the adapter seat 520 tilting, shaking and other problems, thereby reducing the possibility of the baffle plate 400 tilting, shaking and other problems, improving the installation stability of the baffle plate 400, and reducing the vibration of the baffle plate 400 during operation, so as to provide a good grass blocking effect.

[0075] In other embodiments, the first limiting flange 522 may be disposed on a side of the cutter head frame 310 facing the adapter seat 520. The first limiting groove 312 may be disposed on a side of the adapter seat 520 facing the cutter head frame 310.

[0076] like Figure 1 , Figure 3 and Figure 4As shown, the blade mechanism 1000 further includes a protective cover 600, which can be fixedly connected to the side of the housing 221 facing the blade 300 by means of screw connection or clamping. In some embodiments, the protective cover 600 may include an integrated main body 610 and two extensions 620. The main body 610 may be substantially parallel to the blade frame 310, the main body 610 is disposed between the housing 221 and the blade frame 310, and the main body 610 may be fixedly connected to the housing 221 by means of screw connection or clamping. The two extensions 620 may be disposed at opposite ends of the main body 610, and the extensions 620 may extend from the main body 610 toward the direction close to the baffle 400. In an embodiment, the extensions 620 may be spaced apart on the side of the blade 300 and the baffle 400 away from the connecting shaft 510.

[0077] In the embodiment, by providing the protective cover 600, the output direction of grass clippings during mowing can be limited, the phenomenon of grass clippings flying around can be reduced, and grass clippings can be prevented from splashing toward the operator and causing harm to the operator.

[0078] In some embodiments, a third annular limiting flange 630 is protruded from the main body 610 on one side facing the cutter disc holder 310. The third limiting flange 630 is arranged at intervals on the peripheral side of the mounting seat 530. The third limiting flange 630 is arranged at intervals from the cutter disc holder 310 on the side facing the cutter disc holder 310. When the driving member 210 drives the mounting seat 530 and the cutter disc 300 to rotate, the third limiting flange 630 can provide corresponding radial limiting for them, so as to reduce the probability of the cutter disc 300 tilting and other problems, and can also reduce the vibration of the cutter disc 300 during the rotation process, and improve the stability of the cutter disc 300 during the rotation process.

[0079] In some embodiments, the cutter head frame 310 is provided with a protruding annular fourth limiting flange 313 on one side facing the main body 610. The fourth limiting flange 313 may be spaced apart on the peripheral side of the mounting seat 530, and the fourth limiting flange 313 and the mounting seat 530 may cooperate to form a second limiting groove 700. The second limiting groove 700 may be configured as an opening on the side facing the main body 610. The third limiting flange 630 may be movably inserted into the second limiting groove 700, that is, the third limiting flange 630 may be moved relative to the second limiting groove 700. In an embodiment, the fourth limiting flange 313 may also be spaced apart from the third limiting flange 630. The fourth limiting flange 313 may also be spaced apart from the main body 610 on the side facing the main body 610.

[0080] When the driving member 210 drives the cutter disc 300 to rotate, the third limiting flange 630 can move relatively in the second limiting groove 700. In this process, the third limiting flange 630 can provide radial limiting for the fourth limiting flange 313, improve the stability of the cutter disc 300 during rotation, reduce the vibration of the cutter disc 300 during rotation, and reduce the probability of the cutter disc 300 tilting and other problems, thereby ensuring the smooth operation of the cutter disc mechanism 1000.

[0081] The embodiment further provides a lawn mower, which may include the blade disc mechanism 1000 provided in the embodiment.

[0082] In the embodiment, the baffle 400 can be stopped between the blade disc frame 310 and the grass, reducing the possibility of the blade disc frame 310 being entangled by the grass, thereby reducing the probability of problems such as overcurrent in the driving component 210, extending the service life of the driving component 210, and thereby extending the service life of the lawn mower.
