[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] In the process of lawn maintenance, lawn mowing is the most tedious and complicated. In order to reduce its labor intensity and cost, lawn mowing equipment, such as lawn mowing robots, have been developed. The lawn mowing robots are often provided with cutting blades (such as blades), and the lawn is cut and mowed by the rotation of the cutting blades. However, the existing cutting blades are not safe enough and are prone to cause harm to people or objects that accidentally touch the blades.

[0040] Based on this, the present application provides a cutting blade, a cutting mechanism and a cutting device, aiming to improve the cutting safety of the cutting blade and avoid causing harm to people or objects that accidentally touch the blade edge, so as to meet actual usage needs.

[0041] See also Figure 1 , Figure 1 A block diagram of the module structure of a cutting blade 100 provided in an embodiment of the present application is shown in FIG. Figure 2 A schematic diagram of the structure of a cutting blade 100 provided in an embodiment of the present application is shown in FIG. Figure 3 A schematic plan view of the structure of a cutting blade 100 provided in an embodiment of the present application.

[0042] It should be understood that the cutting blade 100 provided in the embodiment of the present application is applied to the cutting device 1, and exemplarily, the cutting device 1 is a lawn mower or a lawn mowing robot, and accordingly, the target objects cut by the cutting blade 100 are grass stems, leaves, branches and other objects.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the present application provides a cutting blade 100, which can be configured to be installed on a cutting device 1 and perform a cutting action.

[0044] The cutting device 1 is, for example, a lawn mower. Specifically, the cutting blade 100 is used to be connected to the lawn mower and can move under the control of the lawn mower to complete a preset cutting action. For example, the above-mentioned cutting action includes but is not limited to reciprocating motion in a preset cutting direction, or circular motion along a preset center, or other set actions.

[0045] The cutting blade includes a base 120 , a plurality of cutting members 130 disposed on the base 120 , and a plurality of protection members 140 disposed on the base 120 . The following describes each part of the cutting blade 100 in detail.

[0046] Specifically, the protective member 140 is located on both sides of each cutting member 130 along the extension direction of the base 120. In the protruding direction of the cutting member 130, the height of the protective member 140 is higher than the height of the cutting member 130, and the protruding direction of the cutting member 130 is perpendicular to the extension direction of the base 120.

[0047] When the cutting blade 100 moves to complete a preset cutting action, if the cutting blade 100 moves toward the protruding direction of the cutting member 130, the cutting member 130 can be used to cut a target object located in the protruding direction of the cutting member 130, such as grass leaves, branches and other objects.

[0048] Since the height of the protective member 140 is higher than the height of the cutting member 130 in the protruding direction of the cutting member 130, when the cutting blade 100 moves toward the protruding direction of the cutting member 130 to cut the target object, smaller objects will first contact the protective member 140 and then the cutting member 130, and the cutting member 130 will cut the target object. However, for larger objects, the target object can be protected by the protective member 140 to avoid being cut by the cutting member 130 of the cutting blade 100, thereby greatly improving the safety of the cutting action.

[0049] Therefore, the embodiment of the present application provides a protective member 140 to improve the cutting safety of the cutting blade 100 and avoid harm to people or objects that accidentally touch the blade edge, so as to meet actual usage requirements.

[0050] Preferably, in the cutting blade 100 provided in the embodiment of the present application, the cutting member 130 and the protective member 140 are integrally formed, so that the manufacturing cost of the cutting blade 100 is reduced and the manufacturing is easy.

[0051] like Figure 1-3 As shown, in some embodiments, a plurality of cutting members 130 and a plurality of protecting members 140 are arranged along the extension direction of the base 120 , and a cutting member 130 is provided between any two adjacent protecting members 140 .

[0052] Specifically, for a single cutting member 130, the protective members 140 are disposed on opposite sides of the cutting member 130 in the extending direction of the base 120. For two adjacent cutting members 130, one cutting member 130 is connected to the other cutting member 130 through the protective member 140, that is, on the surface of the base 120, a plurality of cutting members 130 and a plurality of protective members 140 are alternately arranged along the extending direction of the base 120.

[0053] It should be understood that the cutting piece 130 is used to cut the target object it contacts, while the protective piece 140 can effectively protect larger objects from being cut by the cutting piece 130. Therefore, multiple cutting pieces 130 and multiple protective pieces 140 are arranged at intervals along the extension direction of the base 120, which can take into account the cutting effect and the protective effect at various locations in the extension direction of the base 120.

[0054] Specifically, when the width of the non-cutting object is greater than the distance between two adjacent protective members 140, the non-cutting object will not enter between the two adjacent protective members 140, and the cutting member 130 can play a better protective effect. Therefore, the cutting blade 100 provided in the embodiment of the present application can effectively prevent accidental injury to non-cutting objects such as human bodies or animals.

[0055] In some embodiments, the distance between two adjacent protective members 140 is smaller than the width of a human finger. It should be noted that the above-mentioned finger width is set based on sampled finger width data of multiple people to prevent the user's fingers from entering between two adjacent protective members 140 and being accidentally injured by the cutting member 30 during cutting, causing injury to the user.

[0056] like Figure 1-3 As shown, in some embodiments, the protective member 140 is formed into a serrated shape.

[0057] In other embodiments, the cutting member 130 is formed with a blade.

[0058] It should be noted that the above two embodiments can be implemented separately or in combination, wherein the serrated protective member 140 and / or the blade formed on the cutting member are used to provide a cutting function to ensure that the target object entering between two adjacent protective members 140 is cut.

[0059] Taking the target object as a grass blade and the protective member 140 being formed into a serrated shape as an example, when the cutting member 130 cuts the grass blade, even if the cutting member 130 fails to completely cut off the grass blade at one time, the serrated protective member 140 can tear the grass blade a second time in the direction of the sawtooth formation to ensure the cutting effect.

[0060] like Figure 2 and Figure 3 As shown, in some other embodiments, the protection member 140 has a first surface 141 and a second surface 142 , and an edge 143 is formed at the intersection of the first surface 141 and the second surface 142 .

[0061] Specifically, the first surface 141 is a surface of the tearing portion 141 close to the cutting piece 130 , and the second surface 142 is a surface of the tearing portion 141 extending along an extending direction of the base 120 .

[0062] It should be noted that the above three embodiments: the protective member 140 is formed into a serrated shape, the cutting member is formed with a blade 140, and the protective member 140 forms an edge 143 at the intersection of the first surface 141 and the second surface 142, can be implemented separately or in combination.

[0063] Through the above-mentioned implementation or a similar tearing structure design, when the cutting member 130 cuts grass blades, if the cutting member 130 fails to completely cut off the target object (such as grass blades, branches, etc.) at one time, the serrated protective member 140 and / or the edge 143 formed by the protective member 140 can tear the target object a second time in the direction of its formation, so as to enhance the tearing effect of the cutting blade 100 on the target object.

[0064] Therefore, the cutting blade 100 provided in the embodiment of the present application can improve the cutting effect of the cutting blade 100 and the applicability and cutting effect of cutting different target objects while ensuring cutting safety through the corresponding tearing structure design, especially for the target object entering between two adjacent protective parts 140, further improving the cutting work efficiency to meet actual usage needs.

[0065] See also Figure 4 , Figure 4 A schematic plan view of the structure of another embodiment of the cutting blade 100 provided in the embodiment of the present application.

[0066] like Figure 4 As shown, in some embodiments, in the extension direction of the base 120 , the width of the protective member 140 on a side close to the base 120 is greater than the width of the side away from the base 120 .

[0067] Exemplarily, the protective member 140 is in a trapezoidal shape. Specifically, in the extension direction of the base 120, the side of the protective member 140 close to the base 120 is wide, and the side away from the base 120 is narrow. It should be understood that the provision of the protective member 140 facilitates objects such as blades of grass and branches to enter between two adjacent protective members 140, so that more blades of grass and branches can be cut by the cutting member 130 of the cutting blade 100, thereby improving the cutting effect and cutting efficiency.

[0068] See also Figure 5 , Figure 5 This is a schematic plan view of the structure of another embodiment of the cutting blade 100 provided in the present application.

[0069] like Figures 1 to 5 As shown, in some embodiments, the cutting member 130 and the protection member 140 are disposed on the same side of the base 120 , or the cutting member 130 and the protection member 140 are distributed on opposite sides of the base 120 .

[0070] For example, Figures 1 to 4 In any of the cutting blades 100 shown, the cutting element 130 and the protection element 140 are disposed on the same side of the base 120. Figure 5In the cutting blade 100 shown, a cutting member 130 and a protective member 140 are arranged on opposite sides perpendicular to the extension direction of the base 120, and in the protruding direction of the cutting member 130 on either side, the height of the protective member 140 on the same side is higher than the height of the cutting member 130.

[0071] It should be understood that by arranging the cutting piece 130 on opposite sides of the base 120, when the cutting device 1 drives the cutting blade 100 to move in any of the two convex directions of the cutting piece 130, the cutting blade 100 can achieve effective cutting through the cutting piece 130 on the same side as the movement direction, thereby improving the adaptability of the cutting blade 100 to different cutting actions.

[0072] like Figure 2 As shown, in some embodiments, the cutting blade 100 further includes a drive connection portion 110 connected to the base 120, and the drive connection portion 110 is formed with an adapting hole 111 adapted to be connected and adapted to the drive assembly;

[0073] When the driving assembly is matched with the driving connection portion 110 , the driving assembly and the matching hole 111 form a hole-shaft match.

[0074] Exemplarily, the drive component 200 is disposed on the cutting mechanism 10, and the drive component 200 is adapted to the drive connection part 110 to drive the cutting blade 100 to perform moving cutting, wherein the adapting hole 111 on the drive connection part 110 is configured to cooperate with the hole axis of the drive component 200, and the drive component 200 can drive the cutting blade 100 to rotate around the drive component 200 to perform a corresponding cutting action.

[0075] See also Figure 6 , Figure 6 This is a schematic plan view of the structure of another embodiment of the cutting blade 100 provided in the present application.

[0076] like Figure 6 As shown, in some embodiments, the base 120 includes a first base portion 121 and a second base portion 122 disposed on opposite sides of the driving connection portion 110, and a cutting member 130 and a protective member 140 are disposed on both the first base portion 121 and the second base portion 122.

[0077] Specifically, at least one cutting member 130 and at least one protective member 140 are provided on the first base portion 121 and the second base portion 122, and the first base portion 121 and the second base portion 122 are respectively connected to opposite sides of the driving connection portion 110. Therefore, when the cutting blade 100 moves under the drive of the cutting device 1, the cutting area of ​​the cutting blade 100 is enlarged and the cutting effect is also effectively improved.

[0078] In some embodiments, the cutting element 130 on the first base portion 121 is at least disposed on the first side of the base 120, and the cutting element 130 on the second base portion 122 is at least disposed on the second side of the base 120, and the first side and the second side are opposite sides perpendicular to the extension direction.

[0079] For example, Figure 6 In the embodiment, the cutting member 130 on the first base portion 121 is at least disposed on the first side of the base 120, and the cutting member 130 on the second base portion 122 is at least disposed on the second side of the base 120. Therefore, when the cutting device 1 drives the cutting blade 100 to rotate around the driving connection portion 110 to cut the target object (for example, when driving the cutting blade 100 to rotate as shown in FIG. Figure 6 The cutting member 130 disposed on the first side of the base 120 on the first base portion 121 and the cutting member 130 disposed on the second side of the base 120 on the second base portion 122 can both cut the target object on the same side as themselves, thereby improving the cutting area and cutting efficiency.

[0080] It should be understood that in some embodiments, the cutting elements 130 on the first base portion 121 may also be disposed on opposite sides of the base 120, and the cutting elements 130 on the second base portion 122 may also be disposed on opposite sides of the base 120. That is, a portion of the cutting elements 130 is disposed on the first side of the first base portion 121 and the second base portion 122, and another portion of the cutting elements 130 is disposed on the second side of the first base portion 121 and the second base portion 122.

[0081] Therefore, when the cutting device 1 drives the cutting blade 100 to rotate in two relative directions around the driving connection part 110, corresponding cutting actions can be performed, thereby improving the cutting efficiency of the cutting blade 100 and the adaptability of performing different cutting actions.

[0082] See also Figure 7 , Figure 7 A module structure block diagram of a cutting mechanism 10 provided in an embodiment of the present application.

[0083] like Figure 7 As shown, the present application also provides a cutting mechanism 10 , which specifically includes a cutting blade 100 and a driving assembly 200 .

[0084] The cutting blade 100 is any one of the cutting blades 100 provided in the embodiments of the present application, and the driving assembly 200 is connected to the cutting blade 100 and is used to drive the cutting blade 100 to move to perform a cutting action. Exemplarily, the driving assembly 200 is a motor, and the driving assembly 200 is used to drive the cutting blade 100 to move to perform a cutting action under the condition of an external input current.

[0085] In some embodiments, the drive component 200 is a motor, and the output end of the motor forms a transmission connection with the cutting blade 100, and the drive component 200 is used to drive the cutting blade 100 to rotate under the condition of external input current to perform a cutting action.

[0086] Exemplarily, the cutting blade 100 is disposed on a cutter disc, and the output end of the motor is connected to the cutter disc, and the motor can drive the cutter disc to rotate, so that the cutting blade 100 rotates with the cutter disc to achieve cutting.

[0087] See also Figure 8 , Figure 8 This is a block diagram of the module structure of a cutting device 1 provided in an embodiment of the present application.

[0088] like Figure 8 As shown, the present application further provides a cutting device 1 , which includes: a main body 20 , a cutting mechanism 10 and a traveling mechanism 30 .

[0089] Among them, the cutting mechanism 10 is a cutting mechanism 10 as provided in any one of the embodiments of the present application, and the cutting mechanism 10 is installed on the main body 20 and is used to perform cutting actions, and the traveling mechanism 30 is connected to the main body 20 and is used to drive the cutting device 1 to travel, so as to assist the cutting device 1 to move to the target location for mowing operations.

[0090] For example, the cutting device 1 is a lawn mower or a lawn mowing robot, and accordingly, the target objects cut by the cutting blade 100 are grass stems, leaves, branches and other objects.

[0091] In summary, the embodiment of the present application provides a cutting blade 100, a cutting mechanism 10 and a cutting device 1, wherein the cutting blade 1 includes a base 120, a plurality of cutting parts 130 arranged on the base 120 and a plurality of protective parts 140 arranged on the base 120, wherein the protective parts 140 are located on both sides of each cutting part 130 along the extension direction of the base 120, and in the protruding direction of the cutting part 130, the height of the protective part 140 is higher than the height of the cutting part 130, and the protruding direction of the cutting part 130 is perpendicular to the extension direction of the base 120.
