Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0042] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Please refer to Figure 1 and Figure 2 , wherein, Figure 1 is a schematic diagram of the cutting mechanism provided by the embodiment of the present application, Figure 2 is a cross-sectional view of the cutting mechanism provided by the embodiment of the present application.

[0044] In the first specific embodiment, as shown in Figure 1 and Figure 2 , the cutting mechanism 100 provided by the embodiment of the present application mainly includes a cutter head 1 and a mounting base 2.

[0045] The cutter head 1 is a key component of the cutting mechanism 100, responsible for directly contacting the material to be cut and performing the cutting action.

[0046] The mounting seat 2 is used to fix the cutter head 1, ensuring its stability and accuracy during the cutting process.

[0047] During use, the rotational power of the cutting mechanism 100 is transmitted to the mounting seat 2. Since the cutter head 1 is fixed on the mounting seat 2, the mounting seat 2 drives the cutter head 1 to rotate, thereby realizing the cutting action.

[0048] In this embodiment, the application fields of the cutting mechanism 100 are diverse, such as lawn mowers or lawn mowing robots, but these are only part of the numerous application options. Due to the adaptable and flexible design of the cutting mechanism 100, it can be integrated into various mechanical devices that require a cutting function.

[0049] Please refer to Figure 3 and Figure 4 , in which, Figure 3 is a schematic diagram of the cutter head provided by the embodiment of the present application, Figure 4 is a schematic diagram of the mounting seat provided by the embodiment of the present application.

[0050] In some embodiments, the cutter head 1 is provided with a first hook 11, which is a key structure for realizing the quick fastening of the cutter head. Correspondingly, the mounting seat 2 is provided with a second hook 21 and an anti-reverse part 22, which are arranged along the circumferential direction (i.e., the rotation direction) of the mounting seat 2 and form a cooperating relationship with the first hook 11.

[0051] Specifically, the second hook 21 cooperates with the first hook 11 to fasten the cutter head 1 on the mounting seat 2. The arrangement of the first hook 11 and the second hook 21 allows the cutter head 1 to be tightly combined with the mounting seat 2 by means of clamping, providing a simple and quick installation method.

[0052] The anti-reverse part 22 is used to restrict the rotation of the cutter head 1 relative to the mounting seat 2 to prevent the misalignment of the first hook 11 and the second hook 21. The setting of the anti-reverse part 22 plays a role in restricting the rotation of the cutter head 1 relative to the mounting seat 2, ensuring the positioning accuracy of the cutter head 1 and preventing the risk of reduced cutting efficiency or equipment damage caused by rotational misalignment.

[0053] The cutting mechanism 100 provided by this application, through innovative design, proposes a new solution to the problems of inconvenient disassembly, easy damage and wear of the cutter head 1 in the prior art. First, the first hook 11 provided on the cutter head 1 cooperates with the second hook 21 on the mounting base 2. This design allows the cutter head 1 to be quickly fixed on the mounting base 2 through a simple snapping action, thus avoiding the cumbersome disassembly process of using traditional fasteners such as screws. This fast fastening mechanism significantly improves the efficiency of replacing the cutter head 1 and reduces the risk of damage to the fasteners caused by improper disassembly.

[0054] In addition, the anti-rotation part 22 on the mounting base 2 is designed to effectively limit the rotation of the cutter head 1 relative to the mounting base 2, ensuring the correct cooperation between the first hook 11 and the second hook 21 and preventing misalignment. This anti-misalignment mechanism guarantees the stability of the cutter head 1 during the cutting process and avoids the decline of the cutting effect or equipment damage caused by the displacement of the cutter head 1.

[0055] Therefore, the cutting mechanism 100 simplifies the fastening and disassembly process of the cutter head 1, reduces the operation time, lowers the maintenance cost, and enhances the stability and reliability of the cutter head 1 during fixation through the setting of the anti-rotation part 22.

[0056] Combined with the above structure and process description, it can be seen that the cutting mechanism 100 has at least the following beneficial effects: By setting the first hook 11 on the cutter head 1, the second hook 21 on the mounting base 2 and the anti-rotation part 22, the cutting mechanism 100 realizes the quick fastening and anti-misalignment fixation of the cutter head 1, effectively solves the problems of inconvenient disassembly, easy damage and wear of the cutter head 1 of the traditional cutting mechanism, and improves the stability and service life of the cutting mechanism 100.

[0057] Please continue to refer to Figure 4 , in some embodiments, the number of both the second hooks 21 and the anti-rotation parts 22 is multiple. One second hook 21 and one anti-rotation part 22 form a set of hook groups. Multiple sets of hook groups are arranged along the circumference of the mounting base 2, and a notch 23 is formed between adjacent hook groups. The notch 23 is used for the first hook 11 to enter and exit the mounting base 2.

[0058] In this embodiment, the design of the mounting base 2 includes repetitive unit structures, that is, multiple second hooks 21 and anti-rotation parts 22. These structural units exist in the form of hook groups, and each hook group is composed of one second hook 21 adjacent to one anti-rotation part 22. Such hook groups are arranged continuously along the circumference of the mounting base 2, forming a periodic structural layout.

[0059] Between these hook groups, notches 23 are specifically designed. These notches 23 are located between adjacent hook groups, and their existence is to provide a space so that the first hook 11 can smoothly enter or exit the mounting seat 2. This design allows the cutter head 1 to achieve a quick and easy installation and disassembly process through the interaction between the first hook 11 and the second hook 21.

[0060] During installation, align the first hook 11 on the cutter head 1 with the notch 23 on the mounting seat 2, and axially insert the first hook 11 into the mounting seat 2. At this time, the first hook 11 and the second hook 21 are not yet engaged; rotate the cutter head 1 relative to the mounting seat 2, and after the first hook 11 rotates circumferentially, it engages with the second hook 21 to fasten the cutter head 1 to the mounting seat 2, and the cutter head 1 cannot axially disengage from the mounting seat 2. The anti-reverse part 22 restricts the rotation of the cutter head 1 relative to the mounting seat 2 to prevent the first hook 11 and the second hook 21 from being misaligned.

[0061] During disassembly, rotate the cutter head 1 relative to the mounting seat 2. After the first hook 11 rotates circumferentially, it disengages from the second hook 21, and align the first hook 11 with the notch 23 on the mounting seat 2; axially disengage the first hook 11 from the mounting seat 2. Different from the installation process, the anti-reverse part 22 will restrict the rotation of the cutter head 1 relative to the mounting seat 2 after the cutter head 1 is installed. However, when disassembling the cutter head 1, the cutter head 1 rotates in the opposite direction relative to the mounting seat 2 and will not be hindered by the anti-reverse part 22. Therefore, the restrictive effect of the anti-reverse part 22 on the cutter head 1 is a one-way restriction.

[0062] This periodic arrangement of hook groups and notches 23 not only improves the installation and disassembly efficiency of the cutter head 1, but also enhances the stability of the cutter head 1 on the mounting seat 2 by ensuring the correct engagement between the first hook 11 and the second hook 21. Such a configuration helps to reduce errors during installation, while improving the reliability of the entire cutting mechanism 100 and the convenience of maintenance.

[0063] As Figure 4 shown, a mounting seat 2 with a specific configuration is presented, Figure 4 in which the number of both the second hooks 21 and the anti-reverse parts 22 is two. One second hook 21 and one anti-reverse part 22 form a group. In the circumferential direction, the two groups are spaced apart to form a notch 23, and the notch 23 is used for the first hook 11 on the cutter head 1 to extend into the interior of the mounting seat 2 to achieve the installation of the cutter head 1.

[0064] Please continue to refer to Figure 4 , in some embodiments, the anti-reverse part 22 extends circumferentially on the mounting seat 2. The first end of the anti-reverse part 22 in the circumferential direction is adjacent to the second hook 21 to restrict the rotation of the first hook 11, and a notch 23 is formed between the second end of the anti-reverse part 22 in the circumferential direction and the second hook 21 in the adjacent hook group.

[0065] In this embodiment, the anti-reverse portion 22 is designed to extend circumferentially around the mounting base 2, and this design enables the anti-reverse portion 22 to form a continuous arc-shaped structure. Such a structure not only presents a smooth and unified appearance visually, but also has significant advantages functionally.

[0066] Specifically, the first end of the anti-reverse portion 22 in the circumferential direction is designed to be adjacent to the second hook 21. The main function of this end is to restrict the rotation of the first hook 11, ensuring the correct positioning and fixation of the cutter head 1 on the mounting base 2. This adjacent layout of the anti-reverse portion 22 effectively prevents misalignment between the first hook 11 and the second hook 21, thus guaranteeing the stability of the cutter head 1 and the accuracy of cutting.

[0067] Meanwhile, a notch 23 is formed between the second end of the anti-reverse portion 22 in the circumferential direction and the second hook 21 in the adjacent hook group. The existence of the notch 23 provides a passage for the first hook 11 to enter and exit, making the installation and disassembly process of the cutter head 1 more convenient and rapid.

[0068] Therefore, the anti-reverse portion 22 adopts a continuous arc-shaped structure design. This design not only enhances the integrity and strength of the structure, but also effectively reduces the processing cost by reducing the number of parts and joints. The continuity of the arc-shaped structure helps to improve the stability of the anti-reverse portion 22, simplifies the manufacturing process, and reduces the assembly complexity. In addition, on the basis of ensuring technical efficiency and operation reliability, this design also brings economic benefits, because it realizes the improvement of product performance and the reduction of cost by reducing the additional costs in the production process.

[0069] Please continue to refer to Figure 3 , in some embodiments, the cutter head 1 is provided with an annular flange 12. The annular flange 12 faces the mounting base 2. The first hooks 11 are arranged on the outer side of the annular flange 12. The annular flange 12 is in clearance fit with the anti-reverse portion 22 and in clearance fit with the second hook 21 to enable the annular flange 12 to enter and exit the mounting base 2.

[0070] In this embodiment, the design of the cutter head 1 includes an important structural feature. The annular flange 12 is arranged facing the mounting base 2, and its design purpose is to provide a stable interface so that the cutter head 1 can be smoothly engaged with the mounting base 2. The first hooks 11 are specially arranged on the outer side of the annular flange 12, and these hooks are the key structures for realizing the quick engagement of the cutter head 1 and the mounting base 2.

[0071] The annular flange 12 and the anti-reverse portion 22 on the mounting base 2 and the second hook 21 are in clearance fit. This clearance fit ensures that the annular flange 12 can smoothly perform axial movement and circumferential rotation within the mounting base 2, thereby realizing the process of entering and exiting the mounting base 2. The design of the clearance fit not only ensures the stable installation of the cutter head 1 but also allows the possibility of quick disassembly, improving the operation efficiency and maintenance convenience of the entire cutting mechanism 100.

[0072] Please continue to refer to Figure 4 , in some embodiments, a positioning platform 24 is provided inside the mounting base 2. The positioning platform 24 is used to abut against the end of the annular flange 12 after the annular flange 12 enters the mounting base 2, so as to position the cutter head 1 to prevent the cutter head 1 from skewing.

[0073] In this embodiment, a positioning platform 24 is specially designed inside the mounting base 2. The main function of this positioning platform 24 is to abut against the end of the annular flange 12 after the annular flange 12 of the cutter head 1 completely enters the mounting base 2. Through this abutment, the positioning platform 24 can effectively position the cutter head 1 to ensure its correct alignment within the mounting base 2 and prevent the cutter head 1 from skewing during installation or use.

[0074] This positioning mechanism is crucial for ensuring the cutting accuracy of the cutting mechanism 100 and extending the service life of the cutter head 1. The design of the positioning platform 24 takes into account the simplicity of operation and the stability of the cutter head 1, ensuring that the cutter head 1 can maintain an accurate position and a stable operating state even under high load or long-term operation conditions.

[0075] In addition, the presence of the positioning platform 24 also helps to simplify the installation process because the operator can quickly and accurately position the cutter head 1 into the mounting base 2 through the abutment action of the positioning platform 24. This design reduces the dependence on professional skills, enabling even non-professional personnel to easily complete the installation and disassembly of the cutter head 1 and improving the user-friendliness of the entire cutting mechanism 100.

[0076] Please continue to refer to Figure 3 , in some embodiments, the number of the first hooks 11 is two, and the two first hooks 11 are symmetrically arranged along the circumferential direction of the cutter head 1.

[0077] Please continue to refer to Figure 4 , in some embodiments, the number of the second hooks 21 is two, and the two second hooks 21 are symmetrically arranged along the circumferential direction of the mounting base 2.

[0078] In this embodiment, the symmetric arrangement of the second hook 21 and the first hook 11 not only improves the stability when the cutter head 1 and the mounting seat 2 cooperate with each other, but also helps to ensure that the cutter head 1 is evenly stressed within the mounting seat 2, avoiding skew or damage caused by uneven stress. In addition, while enhancing the stability of the structure, it also helps to simplify the installation and disassembly process. The operator can more easily align the hooks to achieve quick installation, and it is also convenient for maintenance and replacement of the cutter head 1. This design takes into account the user's convenience in use while improving the performance and reliability of the cutting mechanism 100.

[0079] In some embodiments, the second hook 21 is provided on the inner side of the mounting seat 2.

[0080] In this embodiment, the second hook 21 is located on the inner side of the mounting seat 2, while the first hook 11 is located on the outer side of the annular flange 12 of the cutter head 1. Their cooperation relationship further enhances the fixing effect of the cutter head 1. When the cutter head 1 is installed on the mounting seat 2, the interaction between the first hook 11 and the second hook 21 forms a reliable locking mechanism, ensuring that the cutter head 1 remains stable even under high-speed or high-load conditions.

[0081] Please refer to Figure 5 , Figure 5 which is a schematic diagram of the movable structure provided by the embodiment of the present application.

[0082] In some embodiments, the cutter head 1 is further provided with a limiting portion 13; the cutting mechanism 100 further includes a movable structure 3 provided on the mounting seat 2, and the movable structure 3 is used to engage with the limiting portion 13 to prevent the cutter head 1 from rotating relative to the mounting seat 2;

[0083] When the movable structure 3 engages with the limiting portion 13, the second hook 21 cooperates with the first hook 11.

[0084] In this embodiment, the structure of the cutter head 1 also includes a limiting portion 13 for further improving the stability of the cutter head 1 within the mounting seat 2. In addition, the cutting mechanism 100 further includes a movable structure 3, which is provided on the mounting seat 2 and can move to interact with the limiting portion 13 on the cutter head 1.

[0085] The main function of the movable structure 3 is to engage with the limiting portion 13 of the cutter head 1 after the cutter head 1 is installed on the mounting seat 2, thereby preventing the cutter head 1 from rotating relative to the mounting seat 2. This locking mechanism ensures the stability and accuracy of the cutter head 1 during the cutting operation, preventing errors or damage caused by rotation.

[0086] It should be noted that on the basis of the cooperation between the first hook 11 and the second hook 21 to provide locking of the cutter head 1 in the mounting seat 2, the combination relationship between the movable structure 3 and the limiting portion 13 can be regarded as a second locking.

[0087] When the movable structure 3 is snapped into the limiting portion 13, its cooperation with the second hook 21 and the first hook 11 forms a stable locking system. The setting of this structure not only improves the fixing safety of the cutter head 1, but also enhances the reliability of the entire cutting mechanism 100. Through this design, the cutter head 1 can maintain an accurate position during the cutting process, thus ensuring the cutting quality, and at the same time facilitating the operator to perform maintenance and replace the cutter head 1.

[0088] It should be noted that the specific structures of the movable structure 3 and the limiting portion 13 and the movement form of the movable structure 3 are not limited in this embodiment. For example, for the specific structure, the movable structure 3 can be a block structure, and the limiting portion 13 adopts a limiting groove convenient for the block structure to be snapped into; the movable structure 3 can be a rod structure, and the limiting portion 13 adopts a limiting hole convenient for the rod structure to be snapped into. For example, for the movement form, the movable structure 3 can be an axial movement or a radial movement, and the movement mode can be a translation or a rotation, as long as the combination with the limiting portion 13 can be achieved in a certain state of the movement. Therefore, the movable structure 3 and the limiting portion 13 in different embodiments should belong to the scope of description of this application.

[0089] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the mounting seat and the movable structure provided by the embodiment of this application.

[0090] In some embodiments, the movable structure 3 is slidably assembled to the mounting seat 2, and the movement direction of the movable structure 3 is parallel to the axis of the cutting mechanism 100; in the axial direction of the cutting mechanism 100, the cutter head 1 is located below the mounting seat 2; on the movement path of the movable structure 3, when the movable structure 3 moves downward to the first position, the movable structure 3 is snapped into the limiting portion 13.

[0091] In this embodiment, the cutter head 1 is located below the mounting seat 2, which is convenient for cutting operations. At the same time, the movement path of the movable structure 3 is carefully designed to ensure that when it moves downward along the axis and reaches the first position, it can accurately be snapped into the limiting portion 13 on the cutter head 1.

[0092] This design not only ensures the precise cooperation between the movable structure 3 and the limiting portion 13, but also provides a reliable mechanism to prevent the cutter head 1 from rotating during the cutting process. Through this mechanism, the cutter head 1 is firmly positioned within the mounting seat 2, thus ensuring the stability and precision of the cutting operation.

[0093] In addition, the sliding assembly method of the movable structure 3 also simplifies the assembly and maintenance processes of the entire cutting mechanism 100. The operator can easily adjust or replace the movable structure 3 without the need to perform complex disassembly of the entire cutting mechanism 100. This design reflects the consideration of user-friendliness and also improves the maintenance efficiency and service life of the cutting mechanism 100.

[0094] It should be noted that the driving principle of the movable structure 3 is not limited in this embodiment. For example, the movable structure 3 can achieve the function of moving downward to the first position by virtue of its own gravity, or the movable structure 3 can achieve the function of moving downward to the first position by virtue of the elastic force of a passive component such as a spring, or the movable structure 3 can also achieve the function of moving downward to the first position by virtue of the thrust of an active component such as an electric push rod. Therefore, the movable structures 3 in different embodiments should all fall within the scope of description of this application.

[0095] In some embodiments, the middle part of the cutter head 1 is hollowed out; when the cutter head 1 is installed on the mounting seat 2, the middle part of the movable structure 3 is located at the hollowed-out part in the middle of the cutter head 1, and the upward movement of the movable structure 3 is achieved by pressing the middle part of the movable structure 3, so that the movable structure 3 is disengaged from the limiting part 13.

[0096] In this embodiment, the design of the cutter head 1 particularly considers the needs of facilitating user operation and maintenance. Specifically, the middle part of the cutter head 1 is hollowed out. This design not only reduces the weight of the cutter head 1 but also provides an operating space for the movable structure 3. The middle part of the movable structure 3 can be exposed from the hollowed-out part in the middle of the cutter head 1, enabling the user to directly press the middle part of the movable structure 3. In addition, the hollowed-out part in the middle of the cutter head 1 for the middle part of the movable structure 3 to be exposed can be used to help the user locate the cutter head 1 so that the cutter head 1 can be aligned with the installation position.

[0097] Through this design, the user can conveniently achieve the upward movement of the movable structure 3 by pressing the middle part of the movable structure 3. This upward movement enables the movable structure 3 to be disengaged from the limiting part 13. Such an operation method simplifies the disassembly process of the cutter head 1 because the user can quickly replace the cutter head 1 without using tools or performing complex operations.

[0098] This design not only improves the operation convenience but also reduces the risk of equipment damage caused by improper operation. The user can more easily perform the replacement and maintenance work of the cutter head 1, thereby improving the usage efficiency and maintenance convenience of the entire cutting mechanism 100. Through this intuitive and easy-to-operate design, the practicability and reliability of the cutting mechanism 100 are ensured.

[0099] Please continue to refer to Figure 6, in some cases, the movable structure 3 includes a pressing part 31, a moving part 32 and a guiding part 33. The pressing part 31 is located in the middle of the movable structure 3. The function of the pressing part 31 is to facilitate receiving the user's pressing. When the cutter head 1 is installed on the mounting seat 2, the pressing part 31 is located in the hollow part in the middle of the cutter head 1. The moving part 32 is connected to the pressing part 31. The function of the moving part 32 is that when the movable structure 3 moves downward to the first position, the moving part 32 is snapped into the limiting part 13. The guiding part 33 is connected to the moving part 32. The function of the guiding part 33 is to be slidably assembled with the mounting seat 2 to provide guidance for the movement of the movable structure 3.

[0100] In a specific embodiment, the installation and disassembly process of the cutter head 1 and the mounting seat 2 in the cutting mechanism 100 is described as follows.

[0101] During installation, align the first hook 11 on the cutter head 1 with the notch 23 on the mounting seat 2. Since the cutter head 1 is located below the mounting seat 2, the cutter head 1 is lifted upward, the first hook 11 is inserted upward into the mounting seat 2, and the cutter head 1 is rotated forward relative to the mounting seat 2. After the first hook 11 rotates circumferentially, it cooperates with the second hook 21 to fasten the cutter head 1 and the mounting seat 2. At this time, the anti-reverse part 22 restricts the rotation of the cutter head 1 relative to the mounting seat 2, and the restricted direction includes one forward rotation direction to prevent the first hook 11 and the second hook 21 from being misaligned. At the same time, the moving part 32 falls downward into the limiting part 13 to prevent the cutter head 1 from rotating relative to the mounting seat 2, and the restricted directions include two rotation directions, forward and reverse.

[0102] During disassembly, press the pressing part 31 upward to drive the moving part 32 to disengage from the limiting part 13 upward. Rotate the cutter head 1 in the reverse direction relative to the mounting seat 2. After the first hook 11 rotates circumferentially, the cooperation with the second hook 21 is released. Align the first hook 11 with the notch 23 on the mounting seat 2, and the first hook 11 disengages downward from the mounting seat 2, and the cutter head 1 is unloaded downward from the mounting seat 2.

[0103] Please continue to refer to Figure 1 and Figure 2 , in some embodiments, the cutting mechanism 100 further includes:

[0104] A motor 4, connected to the mounting seat 2, and the motor 4 is used to drive the mounting seat 2 to drive the cutter head 1 to rotate;

[0105] A cover 5, connected to the motor 4, and the cover 5 covers the upper side of the cutter head 1.

[0106] In this embodiment, the cutting mechanism 100 further includes two important components: a motor 4 and a housing 5. The motor 4 is connected to the mounting base 2, and its main function is to provide power to drive the mounting base 2, thereby driving the cutter head 1 to rotate. This design enables the cutter head 1 to perform efficient cutting operations under the drive of the motor 4, improving the working performance and efficiency of the entire cutting mechanism 100.

[0107] The housing 5 is fixed to the motor 4. The main function of the housing 5 is to divide the space vertically, ensuring that the cutter head 1 is located on the lower side, thus forming a safety barrier for the user during operation. This design effectively protects the user from possible injuries caused by the rotating cutter head 1 and also prevents debris or other substances from splashing onto the operator or the surrounding environment.

[0108] It should be noted that, except for the content described in this embodiment, other undefined content should not be restricted. For example, the motor 4 can be in a form where the output shaft is directly connected to the mounting base 2, or in other forms; furthermore, how the output shaft is supported and how the rotor and stator in the motor 4 are arranged are not defined in this embodiment.

[0109] It should be noted that many components mentioned in this application are common standard components or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or by conventional experimental methods.

[0110] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0111] The above has introduced the cutting mechanism provided by this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of this application, several improvements and modifications can still be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
