DETAILED DESCRIPTION

[0036] 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.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or it can be indirectly connected to the other element through an intermediate element.

[0039] The terms used in this specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. For example, the descriptions of "first", "second", etc. in the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0040] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] See also Figure 1-Figure 3As shown, the embodiment of the present application proposes a cutting device 100, including a mounting member 10, a cutting member 20, a driving member 30 and an abutment member 40, wherein the cutting member 20 is mounted on the mounting member 10, and the cutting member 20 is used to cut the target object; the driving member 30 is used to drive the mounting member 10 to move, so that the mounting member 10 drives the cutting member 20 to move within a preset area; the abutment member 40 is located below the mounting member 10, and is used to abut against an object below the preset area.

[0042] In a specific application, the preset area may be a cutting area of ​​the cutting member 20 within a certain height range. The movement trajectory of the cutting member 20 covers the preset area to cut the target object in the preset area. The target object may be grass or other plants to be cut. The object below the preset area may be an obstacle or the ground. The obstacle may be the foot of an operator who accidentally extends under the cutting member 20 or other objects such as stones on the ground. When the foot of the operator accidentally extends under the cutting member 20, the abutment member 40 interferes with the foot of the operator to prevent the foot of the operator from directly contacting the cutting member 20 and causing injury.

[0043] In some embodiments, the abutment member 40 is connected to the cutting member 20, and the connection can be direct or indirect. The friction between the abutment member 40 and the operator's foot forms resistance. Since the abutment member 40 is connected to the cutting member 20, the cutting speed of the cutting member 20 can be reduced, thereby preventing the high-speed cutting member 20 from causing secondary damage to the operator's feet.

[0044] In addition, when the abutment member 40 contacts an object below the preset area, such as the ground or a stone, it can also generate a reaction force to drive the cutting member 20 to rise in height, thereby preventing the cutting member 20 from directly contacting the object below the preset area and causing injury.

[0045] Therefore, the cutting device 100 proposed in the embodiment of the present application, through the setting of the abutment member 40, can interfere with the object when it appears below the preset area, and can drive the cutting member 20 away from the object below the preset area. At the same time, it can also reduce the cutting speed of the cutting member 20, avoid the high-speed cutting member 20 from contacting the object and causing secondary damage, thereby improving the safety of the cutting device 100.

[0046] In some embodiments, the cutting member 20 has a first side 20a and a second side 20b that are arranged opposite to each other; wherein the driving member 30 is located on the first side 20a of the cutting member 20, the abutting member 40 is located on the second side 20b of the cutting member 20, and the preset area is located between the driving member 30 and the abutting member 40. This is to avoid interference between the driving member 30 and the abutting member 40 when the cutting member 20 moves in the preset area. In addition, the driving member 30 and the abutting member 40 are respectively arranged on opposite sides of the cutting member 20, which has a compact structure and reduces the volume, and allows the abutting member 40 to face below the preset area, thereby avoiding direct contact between the cutting member 20 and obstacles below.

[0047] When in use, the cutting device 100 can be installed on an autonomous mobile device such as a lawn mower. After the cutting device 100 is installed on the lawn mower, the first side 20a and the second side 20b are the upper and lower sides of the cutting member 20, the driving member 30 is located above the mounting member 10, and the abutment member 40 is located below the mounting member 10, and the lower part is the side of the cutting device 100 close to the ground.

[0048] In some embodiments, Figure 3 and Figure 5 As shown, the abutting member 40 has an abutting surface 41 on the side facing away from the cutting member 20; the distance between the edge of the abutting surface 41 and the cutting member 20 is smaller than the distance between the center of the abutting surface 41 and the cutting member 20. That is, the center position of the abutting surface 41 is more protruding relative to the cutting member 20 than the edge position thereof, and the abutting surface 41 can contact with an object below the preset area through the protruding position of the center of the abutting surface 41, thereby facilitating the abutting surface 41 to drive the cutting member 20 to be raised in height, thereby preventing the cutting member 20 from directly contacting the object and causing damage.

[0049] Optionally, the abutment surface 41 is a convex curved surface structure. Thus, by setting the curved surface structure, friction can be reduced when contacting obstacles. For example, when the operator's foot accidentally extends under the cutting member 20, the curved surface structure of the abutment member 40 can contact the operator's foot, thereby reducing damage to the operator.

[0050] Of course, the abutting surface 41 is not limited to the above-mentioned configuration, for example, in other embodiments, the distance between the edge of the abutting surface 41 and the cutting member 20 is equal to the distance between the center of the abutting surface 41 and the cutting member 20. That is, the distances between the center position of the abutting surface 41 and the edge position thereof relative to the cutting member 20 may also be equal.

[0051] Optionally, the abutting surface 41 is a planar structure. The shape of the abutting surface 41 can be circular or other regular or irregular shapes, so that the volume of the cutting device 100 in the height direction is smaller and cutting can be performed close to the ground.

[0052] In some embodiments, Figure 2, Figure 3 and Figure 6 As shown, the mounting member 10 is connected to the output shaft of the driving member 30, and the abutment member 40 is connected to the mounting member 10. Thus, the mounting member 10 is used to mount the cutting member 20 and the abutment member 40, and is connected to the output shaft of the driving member 30 to transmit the driving force of the driving member 30 to the abutment member 40 and the cutting member 20, thereby driving the abutment member 40 and the cutting member 20 to rotate synchronously.

[0053] As an embodiment, the abutment member 40 and the cutting member 20 can be respectively installed on the mounting member 10, for example, the abutment member 40 is fixed to the mounting member 10 by a screw, and the cutting member 20 is fixed to the mounting member 10 by another screw, and the abutment member 40 is located below the cutting member 20.

[0054] As another embodiment, the abutment member 40 and the cutting member 20 can be installed on the mounting member 10 by the same set of fasteners, for example, a set of screws are used to simultaneously connect the abutment member 40 and the cutting member 20 and fix them to the mounting member 10, so that the abutment member 40 is located below the cutting member 20.

[0055] As another embodiment, the cutting member 20 can be installed above the abutment member 40, and the abutment member 40 can be installed on the mounting member 10, for example, the cutting member 20 can be fixed above the abutment member 40 by screws, and then the abutment member 40 can be fixed to the mounting member 10 by another screw or other fasteners.

[0056] In some embodiments, Figure 2 and Figure 6 As shown, the mounting member 10 and the abutting member 40 are connected by a first connecting member 50, and the first connecting member 50 is disposed through the cutting member 20. Thus, the abutting member 40 is connected to the mounting member 10 by the first connecting member 50, and the cutting member 20 is fixed between the abutting member 40 and the mounting member 10, which is convenient for disassembly and assembly, and the structure is compact after installation, and the volume is reduced.

[0057] In some embodiments, the first connecting member 50 may be integrally connected to the abutting member 40 to improve structural stability. Of course, in other embodiments, the first connecting member 50 may also be separately connected to the abutting member 40 .

[0058] In other embodiments, the mounting member 10 and the abutting member 40 may also be integrally formed to enhance structural stability.

[0059] In some embodiments, the first connecting member 50 includes a first convex column 51 and a fastener, the first convex column 51 is disposed on one of the mounting member 10 and the abutment member 40 and is located between the mounting member 10 and the abutment member 40, the end of the cutting member 20 is provided with a convex ring 21 corresponding to the first convex column 51, the convex ring 21 is sleeved on the first convex column 51, and the fastener is passed through the first convex column 51 and the convex ring 21 and fixed to the other of the mounting member 10 and the abutment member 40. Therefore, by providing the first convex column 51 and the convex ring 21, it is possible to facilitate the positioning of the fastener, thereby facilitating the connection and installation between the abutment member 40, the cutting member 20 and the mounting member 10.

[0060] For example, Figure 2 and Figure 4 As shown, the first protrusion 51 is provided on the abutment member 40 and protrudes toward the mounting member 10, the mounting member 10 is provided with a mounting hole 11 corresponding to the first protrusion 51, and the fastener is passed through the first protrusion 51 and the first protruding ring 21 and fixed to the mounting hole 11 of the mounting member 10, so as to facilitate the abutment member 40 and the cutting member 20 to be fixed to the mounting member 10 through the same set of mounting members 10. Of course, in other examples, the first protrusion 51 can also be provided on the mounting member 10, the first protrusion 51 of the mounting member 10 is correspondingly arranged with the protruding ring 21 of the cutting member 20, and the fastener is passed through the first protrusion 51 and the first protruding ring 21 and fixed to the abutment member 40.

[0061] Exemplarily, the fasteners may be screws, and fixing with screws is not only convenient for assembly and disassembly but also simple to operate and has low installation cost.

[0062] In some embodiments, there are two cutting members 20; the mounting member 10 and the abutting member 40 are connected via two first connecting members 50, each first connecting member 50 cooperates with one cutting member 20, and the cutting member 20 can rotate around the first connecting member 50. Thus, by providing two first connecting members 50, the connection stability between the abutting member 40 and the mounting member 10 can be improved.

[0063] In some embodiments, Figure 2 , Figure 5 and Figure 6As shown, the mounting member 10 and the abutting member 40 are further connected by two second connecting members 60; wherein, the two cutting members 20 are respectively a first cutting member 201 and a second cutting member 202, and the first cutting member 201 abuts against one of the two second connecting members 60 when it rotates clockwise to the first position, and the second cutting member 202 abuts against the other of the two second connecting members 60 when it rotates clockwise to the second position, and the first cutting member 201 abuts against the other of the two second connecting members 60 when it rotates counterclockwise to the third position, and the second cutting member 202 abuts against one of the two second connecting members 60 when it rotates counterclockwise to the fourth position. Thus, by setting the two second connecting members 60, the rotation range of the two cutting members 20 can be limited, thereby preventing the two cutting members 20 from colliding with each other.

[0064] Exemplarily, the cutting member 20 is a blade, and the two blades are arranged axially symmetrically relative to the output shaft of the driving member 30. A first convex ring 21 is arranged at the opposite ends of the two blades, and the arrangement of the two blades can improve the cutting efficiency.

[0065] Exemplarily, the two first connecting members 50 can be symmetrically arranged so that the two cutting members 20 are symmetrically arranged. The second connecting member 60 can include a second boss 61 provided on the abutment member 40 and convexly arranged toward the mounting member 10, and is used to be mounted to the mounting member 10, the two first bosses 51 and the two second bosses 61 are staggered around the center position of the abutment member 40, and the arrangement direction of the two second bosses 61 is perpendicular to the arrangement direction of the two first bosses 51, so as to improve the connection stability between the abutment member 40 and the mounting member 10, and at the same time, the two second bosses 61 can be used to limit the rotation range of the two cutting members 20, so that the rotation range of the two cutting members 20 is equal and does not interfere with each other.

[0066] In some embodiments, Figure 2-Figure 4 As shown, the cutting device 100 further includes a fan structure 70, which is connected to the output shaft of the driving member 30 and is located between the driving member 30 and the cutting member 20. The fan structure 70 is used to rotate under the drive of the driving member 30 to drive the airflow to blow toward the cutting member 20. When the cutting member 20 cuts the target object such as the lawn, garbage such as broken leaves may be thrown into the cutting device 100, for example, toward the driving member 30, thereby affecting the operation of the driving member 30. By setting the fan structure 70, an airflow blowing toward the ground can be formed, thereby blowing out garbage such as broken leaves, and preventing garbage such as broken leaves from entering the cutting device 100.

[0067] In some embodiments, the fan structure 70 includes a base plate 71 and a plurality of blades 72. The base plate 71 is connected to the output shaft of the driving member 30. The base plate 71 is provided with a connecting shaft 711 protruding toward the output shaft of the driving member 30. The plurality of blades 72 are arranged around the outer periphery of the connecting shaft 711. The fan structure 70 can be the same component as the mounting member 10, that is, the base plate 71 can be used to connect the cutting member 20 and the abutment member 40, so that the driving member 30 can simultaneously drive the fan structure 70, the cutting member 20 and the abutment member 40 to rotate.

[0068] In some embodiments, the center positions of the output shaft of the driving member 30, the fan structure 70 and the abutment member 40 are located on the same straight line. The output shaft of the driving member 30 can be connected to the fan structure 70 through a transmission structure such as a coupling or a reducer to facilitate the driving member 30 to drive the fan structure 70, the abutment member 40 and the cutting member 20 to rotate synchronously.

[0069] Of course, in another embodiment, the fan structure 70 may be a different component from the mounting member 10. The fan structure 70 may be disposed on the mounting member 10 and connected to the output shaft of the driving member 30 through the mounting member 10. The driving member 30 drives the mounting member 10 to rotate to drive the fan structure 70 to rotate for blowing air.

[0070] In some embodiments, Figure 1 and Figure 7 As shown, the cutting device 100 also includes a mounting mechanism 80, which includes a fixing portion 81 and a connecting rod assembly 82. The fixing portion 81 is used to be mounted on the body of the autonomous mobile device; one end of the connecting rod assembly 82 is rotatably connected to the fixing portion 81, and the other end of the connecting rod assembly 82 is rotatably connected to the driving member 30, so that the driving member 30, the cutting member 20 and the abutting member 40 as a whole can move up and down relative to the fixing portion 81 through the connecting rod assembly 82. Therefore, by setting the connecting assembly, the abutting member 40 can drive the cutting member 20 to be lifted up under the action of an external force, such as when it is lifted by the ground or an object such as a stone on the ground, so that the driving member 30, the cutting member 20 and the abutting member 40 as a whole can float up and down according to the height of the ground to adapt to the undulating terrain.

[0071] The embodiment of the present application further provides an autonomous mobile device, comprising a body and the above-mentioned cutting device 100, wherein the cutting device 100 is installed on the body. In a specific application, the autonomous mobile device may be a lawn mowing robot capable of autonomous movement.

[0072] The structure and function of the cutting device 100 in the autonomous mobile device proposed in the embodiment of the present application are the same as those in the above embodiment. For details, please refer to the description of the above embodiment, and this embodiment will not be repeated.

[0073] Those skilled in the art may combine and associate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

[0074] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
