[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 23, 2023, with application number 202320590519.4 and application name “Lawn Mower”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electric tools, and in particular to a lawn mower. Background Art

[0003] With the development of automation technology and artificial intelligence, smart lawn mowers can automatically perform mowing tasks, saving people a lot of time and providing great convenience to life.

[0004] Due to safety regulations and energy consumption requirements, smart lawn mowers on the market are generally designed with smaller blades, which reduces the cutting width and makes it impossible to cut grass at the edge of the lawn. The edge of the lawn needs to be trimmed manually, which reduces the degree of automation of the smart lawn mower.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0006] An embodiment of the present application provides a lawn mower that can increase the cutting width.

[0007] In a first aspect, the present application provides a lawn mower, which includes a body, the body having an output shaft, the body having a first side edge and a second side edge arranged opposite to each other along a first direction, the first direction intersecting with the forward direction of the lawn mower. A cutting mechanism, located below the body and installed in cooperation with the output shaft, for performing a cutting operation driven by the output shaft. And a protection mechanism, the protection mechanism is arranged below the body, and the protection mechanism is arranged between the first side edge and the cutting mechanism and between the second side edge and the cutting mechanism.

[0008] The lawn mower in the embodiment of the present application can improve the safety performance of the lawn mower by arranging the protection mechanism between the cutting mechanism and the first side edge of the body and between the cutting mechanism and the second side edge of the body, and arranging the protection mechanism to provide protection at the first side edge, the second side edge and the bottom of the body. In addition, the size of the cutting mechanism can be increased while ensuring safety regulations, thereby obtaining a larger cutting width. This allows the lawn mower to get closer to the edge of the grass being cut, thereby having a larger cutting range, reducing the range of manual trimming, and thus improving the automation of the intelligent lawn mower.

[0009] In a possible implementation, the body has a third side edge and a fourth side edge arranged relatively to each other along a second direction, and the second direction is the forward direction of the lawn mower; wherein, between the first side edge and the cutting mechanism, between the second side edge and the cutting mechanism, between the third side edge and the cutting mechanism, and between the fourth side edge and the cutting mechanism, only between the first side edge and the cutting mechanism, between the second side edge and the cutting mechanism, and between the fourth side edge and the cutting mechanism, the protective mechanism is provided.

[0010] By not providing the protection mechanism between the third side edge and the cutting mechanism, the structure of the lawn mower can be simplified, thereby reducing the cost.

[0011] In a possible implementation, the body has a third side edge and a fourth side edge arranged relatively to each other along a second direction, and the second direction is the forward direction of the lawn mower; wherein, between the first side edge and the cutting mechanism, between the second side edge and the cutting mechanism, between the third side edge and the cutting mechanism, and between the fourth side edge and the cutting mechanism, only between the first side edge and the cutting mechanism and between the second side edge and the cutting mechanism is provided with the protective mechanism.

[0012] By not providing a protective mechanism between the fourth edge and the cutting mechanism, the structure of the lawn mower can be further simplified and the cost can be further reduced.

[0013] In a possible implementation manner, the first direction is perpendicular to a forward direction of the lawn mower.

[0014] By setting the first direction perpendicular to the forward direction of the lawn mower, the safety performance of the lawn mower can be improved. For example, when the two ends located in the forward direction of the lawn mower are the front end and the rear end of the lawn mower, respectively, the first direction is set perpendicular to the forward direction of the lawn mower, and the first side edge and the second side edge of the body are the left side and the right side of the lawn mower, so that both the left side and the right side of the lawn mower can be protected, thereby improving the safety performance of the lawn mower.

[0015] In a possible implementation, in the first direction, the distance between the outer edge of the cutting mechanism and the first side edge of the fuselage is a first distance, and the distance between the outer edge of the cutting mechanism and the second side edge of the fuselage is a second distance. In the second direction, the distance between the outer edge of the cutting mechanism and the third side edge of the fuselage is a third distance. The third distance is greater than the first distance and greater than the second distance.

[0016] By setting the third distance to be greater than the first distance and greater than the second distance, it can be ensured that the distance between the cutting mechanism and the third side edge of the fuselage is larger, thereby ensuring higher safety performance at the third side edge of the fuselage.

[0017] In a possible implementation, in the second direction, the distance between the outer edge of the cutting mechanism and the fourth side edge of the body is a fourth distance, which is greater than the first distance and greater than the second distance.

[0018] By setting the fourth distance to be greater than the first distance and greater than the second distance, it can be ensured that the distance between the cutting mechanism and the fourth side edge of the fuselage is larger, thereby ensuring higher safety performance at the fourth side edge of the fuselage.

[0019] In a possible implementation, the protection mechanism includes a first protection portion and a second protection portion. The first protection portion is disposed between the first side edge and the cutting mechanism and between the second side edge and the cutting mechanism, and the first protection portion is used to protect the side of the cutting mechanism. At least part of the structure of the second protection portion is disposed below the cutting mechanism, and the second protection portion is used to protect below the cutting mechanism.

[0020] By configuring the protection mechanism to include a first protection part and a second protection part, different positions of the protection mechanism can be used for protection at different positions of the lawn mower, thereby improving the safety of the lawn mower.

[0021] In a possible implementation manner, the first protection portion is in a plate shape.

[0022] By setting the first guard part in a plate shape, the structure of the first guard part can be simplified so that the first guard part can protect the first side edge and the second side edge of the machine body. In addition, the plate-shaped structure has good blocking performance and can prevent objects from contacting the cutting mechanism from the first side edge and the second side edge of the machine body, thereby improving the safety of the lawn mower.

[0023] In a possible implementation, at least one grass inlet is formed at at least one end of the second protective portion along the forward direction of the lawn mower.

[0024] By arranging a grass inlet at at least one end of the second protective part, when the lawn mower is used to mow grass, the grass can contact the cutting mechanism through the grass inlet and then be cut by the cutting mechanism, so as to achieve the purpose of mowing the grass.

[0025] In a possible implementation, the body has a third side edge and a fourth side edge that are arranged opposite to each other along a second direction, and the second direction is the forward direction of the lawn mower. In the second direction, the third side edge is located in front of the fourth side edge. In the second direction, at least one grass inlet is provided at one end of the second guard portion facing the third side edge. Alternatively, in the second direction, at least one grass inlet is provided at both ends of the second guard portion.

[0026] By setting the grass inlet at one end of the second protective part facing the third side edge, it is convenient for the grass to contact the cutting mechanism through the grass inlet and then be cut by the cutting mechanism when the lawn mower moves forward, so as to achieve the purpose of mowing. By providing a plurality of grass inlets at both ends of the second protective part, it is convenient for the grass to contact the cutting mechanism through the grass inlet and then be cut by the cutting mechanism when the lawn mower moves forward and backward, so as to achieve the purpose of mowing. In addition, when the lawn mower moves forward, the grass inlet facing the fourth side edge of the fuselage can be used as a grass discharge port, that is, the grass cut by the cutting mechanism can be discharged through the grass inlet facing the fourth side edge of the fuselage to prevent the cutting mechanism from being stuck.

[0027] In a possible implementation, the protection mechanism further includes a mounting portion connected to the fuselage, wherein the first protection portion is connected to the mounting portion, and the second protection portion is connected to the mounting portion or to the first protection portion.

[0028] The installation part is provided so as to connect the first guarding part and the second guarding part with the machine body, and improve the connection stability between the first guarding part and the second guarding part and the machine body, thereby improving the service life of the lawn mower.

[0029] In a possible implementation, in the vertical direction, one end of the second protection portion facing the fuselage is connected to the mounting portion, and one end of the second protection portion facing away from the fuselage is located below the cutting mechanism.

[0030] The end of the second protection part facing away from the fuselage is arranged to be located below the cutting mechanism, so that the second protection part can provide protection below the cutting mechanism.

[0031] In a possible implementation, the second protection portion includes at least two strips, and the at least two strips are respectively installed in cooperation with the installation portion. The at least two strips are arranged at intervals in the first direction. The gap between adjacent strips forms the grass inlet.

[0032] By configuring the second guard part to be at least two strips, the structure of the second guard part can be simplified, making it easier to process and install, thereby reducing costs. Furthermore, the strips are arranged at intervals to directly form a grass inlet without the need to set a specific grass inlet, thereby simplifying the structure of the second guard part and reducing costs.

[0033] In a possible implementation, the body has a third side edge and a fourth side edge arranged opposite to each other along a second direction, and the second direction is a forward direction of the lawn mower. In the second direction, at least one end of each of the strips is provided with a bent portion, and the bent portion extends toward the mounting portion. In the second direction, at least one of the bent portions on each of the strips is connected to the mounting portion.

[0034] By arranging a bending portion on the strip-shaped member, the strip-shaped member is connected to the mounting portion, thereby improving the connection stability between the second protection portion and the mounting portion.

[0035] In a possible implementation, in the second direction, each of the strips is provided with the bending portion at one end close to the third side edge of the fuselage, and each of the strips is connected to the mounting portion via the bending portion. Alternatively, each of the strips is provided with the bending portion at one end close to the fourth side edge of the fuselage, and each of the strips is connected to the mounting portion via the bending portion.

[0036] By providing a bent portion at one end of the strip close to the third side edge of the body, the connection stability between the strip and the mounting portion can be improved. By providing a bent portion at one end of each strip close to the fourth side edge of the body, the obstruction of the second protective part in the forward direction of the lawn mower can be reduced, and the grass can be easily entered from the grass inlet and contacted with the cutting mechanism, thereby improving the efficiency of the lawn mower.

[0037] In a possible implementation, the second protection portion further includes a connecting portion. When the bending portion is provided at one end of each of the strips close to the third side edge of the fuselage, the connecting portion is connected to one end of each of the strips close to the fourth side edge of the fuselage.

[0038] By providing a connecting portion at one end of the second protecting portion where no bending portion is provided, the structural stability of the second protecting portion can be improved.

[0039] In a possible implementation manner, in the second direction, both ends of each of the strip-shaped members are provided with the bending portions.

[0040] By providing bending portions at both ends of the strip, the connection stability between the second protection portion and the mounting portion can be improved, thereby increasing the service life of the second protection portion.

[0041] In a possible implementation, the mounting portion, the first protection portion, and the second protection portion are integrally formed.

[0042] By integrally forming the mounting portion, the first protection portion and the second protection portion, the structural strength of the protection mechanism can be improved.

[0043] In a possible implementation manner, the strip is cylindrical.

[0044] By setting the strip piece to be cylindrical, the processing difficulty of the strip piece can be reduced, thereby reducing the cost. In addition, the cylindrical structure has a smooth surface, no sharp corners, etc., and will not accidentally scratch the user, and has a higher safety performance.

[0045] In a possible implementation, the second protection portion is disposed at an end of the first protection portion away from the fuselage. The second protection portion comprises a plate-like structure, and in the first direction, the second protection portion extends from an outer edge of the cutting mechanism to a center of the cutting mechanism.

[0046] By arranging the second guard part at the end of the first guard part away from the fuselage, the first guard part and the second guard part can be connected without connecting the second guard part to the mounting part, which can simplify the structure of the mounting part and reduce costs. In addition, the guard mechanism can be made into an integral part, which is convenient for processing, and can improve the structural strength of the guard mechanism and increase the service life of the guard mechanism. In addition, by arranging the second guard part in the first direction from the end of the first guard part away from the fuselage to the direction close to the central axis of the cutting mechanism, the obstruction of the second guard part in the second direction can be reduced, which facilitates grass feeding and improves mowing efficiency.

[0047] In a possible implementation, a guide plate is provided at the grass inlet, wherein the guide plate extends toward the machine body.

[0048] By providing a guide plate, grass that is partially bent or fallen can be guided into the grass inlet through the guide plate, thereby improving cutting efficiency.

[0049] In a possible implementation manner, in the first direction, the cutting mechanism is located in the middle of the fuselage.

[0050] By arranging the cutting mechanism in the middle of the fuselage, the distances from the cutting mechanism to the first side edge and the second side edge can be made the same. In this way, when the lawn mower is in operation, the force positions of the first side edge and the second side edge of the fuselage are symmetrical, so that the fuselage is easier to maintain balance and is not easy to tip over.

[0051] In a possible implementation, the cutting width of the cutting mechanism is 260 mm to 300 mm.

[0052] By setting the cutting width of the cutting mechanism to 260 mm to 300 mm, the size of the cutting mechanism can be enlarged, thereby expanding the mowing area of ​​the lawn mower and improving the mowing efficiency.

[0055] According to a second aspect of the present application, there is provided a lawn mower, comprising a body, the body having a first side edge and a second side edge arranged opposite to each other along a first direction, the first direction intersecting with the forward direction of the lawn mower. A cutting mechanism is located below the body and is used to perform a cutting operation. In the first direction, the distance between the outer edge of the cutting mechanism and the first side edge of the body is a first distance, the distance between the outer edge of the cutting mechanism and the second side edge of the body is a second distance, and the first distance and / or the second distance is less than 50 mm.

[0056] By setting the first distance and / or the second distance to be less than 50 mm, it can be ensured that the distance from the cutting mechanism to the outside of the body is small, which is conducive to the lawn mower being closer to the edge of the grass being cut, reducing the scope of manual mowing, thereby improving the automation of the smart lawn mower. In addition, the body width of the lawn mower is small, which can realize the miniaturization of the lawn mower and reduce the cost. In addition, the small distance from the outer edge of the cutting mechanism to the edge of the body can provide better visibility, and the user can see the cutting mechanism and the edge of the lawn more clearly, thereby mowing more accurately.

[0057] In a possible implementation manner, the first distance and / or the second distance is / are less than 45 mm.

[0134] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0135] The lawn mower provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0136] Figure 1 A top view of a lawn mower provided in an embodiment of the present application. Figure 2 A side view of a lawn mower provided in an embodiment of the present application. Figure 3 A bottom view of a lawn mower provided in an embodiment of the present application.

[0137] The present application provides a lawn mower 100, such as Figure 1 As shown, the lawn mower 100 may include a body 10 having an output shaft (not shown in the figure), and the body 10 has a first side edge 11 and a second side edge 12 arranged opposite to each other along a first direction, and the first direction intersects with the forward direction of the lawn mower 100.

[0138] For example, the first direction may be perpendicular to the forward direction of the lawn mower 100, or the first direction may be set at an angle to the forward direction of the lawn mower 100, for example, 85°, 86°, etc. In the embodiment of the present application, the angle between the first direction and the forward direction of the lawn mower 100 is not further limited.

[0139] By setting the first direction perpendicular to the forward direction of the lawn mower 100, the safety performance of the lawn mower 100 can be improved. For example, when the two ends located in the forward direction of the lawn mower 100 are the front end and the rear end of the lawn mower 100, respectively, the first direction is set perpendicular to the forward direction of the lawn mower 100, and the first side edge and the second side edge of the body 10 are the left and right sides of the lawn mower 100, so that there can be protective barriers on both the left and right sides of the lawn mower 100, thereby improving the safety performance of the lawn mower 100.

[0140] like Figure 2 As shown, the lawn mower 100 may further include a cutting mechanism 20, wherein the cutting mechanism 20 is located below the body 10 and is installed in cooperation with the output shaft, and is used to perform cutting operations driven by the output shaft.

[0141] Exemplarily, the rotation centerline of the cutting mechanism 20 coincides with the axis of the output shaft. A control device may be provided on the fuselage 10, and the control device is used to drive the output shaft to rotate, and the output shaft rotates to drive the rotating structure to rotate, so that the rotating structure can perform cutting operations.

[0142] In some embodiments, the control device may be a motor, etc. In the embodiments of the present application, the specific structure of the control device is not further limited.

[0143] In a possible implementation, in the first direction, the cutting mechanism 20 may be located in the middle of the fuselage 10. By arranging the cutting mechanism 20 in the middle of the fuselage 10, the distances from the cutting mechanism 20 to the first side edge 11 and the second side edge 12 can be the same, so that when the lawn mower 100 is in operation, the force positions of the first side edge 11 and the second side edge 12 of the fuselage 10 are symmetrical, so that the fuselage 10 is easier to maintain balance and is not easy to tip over.

[0144] like Figure 3 As shown, the lawn mower 100 may further include a protective mechanism 30, which is disposed below the body 10. The protective mechanism 30 is disposed between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20. The protective mechanism 30 is used to establish a protective barrier at the first side edge 11, the second side edge 12 and below the body 10.

[0145] The lawn mower 100 in the embodiment of the present application can improve the safety performance of the lawn mower 100 by arranging the protection mechanism 30 between the cutting mechanism 20 and the first side edge 11 of the fuselage 10 and the cutting mechanism 20 and the second side edge 12 of the fuselage 10, and the protection mechanism 30 can be arranged to establish a protection barrier at the first side edge 11, the second side edge 12 and the bottom of the fuselage 10. In addition, the size of the cutting mechanism 20 can be increased while ensuring safety regulations, thereby obtaining a larger cutting width. In this way, the lawn mower 100 can be closer to the edge of the grass being cut, thereby having a larger cutting range, reducing the range of manual trimming, and thus improving the automation of the intelligent lawn mower 100.

[0146] The lawn mower 100 in the embodiment of the present application may further include a driving wheel 40 and a driven wheel 50. The driving wheel 40 may be installed at the front end of the body 10, and the driven wheel 50 may be installed at the rear end of the body 10. Alternatively, the driving wheel 40 may be installed at the rear end of the body 10, and the driven wheel 50 may be installed at the front end of the body 10. Figure 3As shown, two driving wheels 40 are respectively installed on the outside of the front end of the machine body 10. Of course, the two driving wheels 40 can also be installed on the outside of the front end of the machine body 10. The driving wheel 40 is driven by the motor on the machine body 10, that is, the lawn mower 100 is a front-drive type lawn mower 100, and the driven wheel 50 is installed on the inside of the rear end of the machine body 10. The driven wheel 50 is preferably a universal wheel. By arranging the driving wheel 40 and the driven wheel 50, the lawn mower 100 can move and turn.

[0147] There are two driving wheels 40 and two driven wheels 50. In other embodiments, only one driven wheel 50 may be provided, or the number of driven wheels 50 may be increased as needed, and the number of driving wheels 40 may be increased or decreased as needed. In the embodiment of the present application, the number of driving wheels 40 and driven wheels 50 is not further limited.

[0148] Exemplarily, the direction from the driven wheel 50 to the driving wheel 40 is the forward direction of the lawn mower 100. By arranging the driving wheel 40 on the outer side of the front end of the fuselage 10, sufficient space is left at the bottom of the front end of the fuselage 10 for grass to enter, thereby avoiding the traditional method of installing the driven wheel 50 at the bottom of the front end of the fuselage 10, which makes the driven wheel 50 crush the grass when the fuselage 10 moves forward, thereby hindering the rear cutting mechanism 20 from cutting the grass.

[0149] In a possible implementation, the body 10 has a third side edge 13 and a fourth side edge 14 arranged opposite to each other along a second direction, and the second direction is the forward direction of the lawn mower 100. Among them, between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, between the third side edge 13 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20, only between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20 are provided with a protection mechanism 30. No protection mechanism 30 is provided between the third side edge 13 and the cutting mechanism 20.

[0150] It should be noted that, for the convenience of description, the Q direction in the figure represents the forward direction of the lawn mower, that is, the second direction. The L direction in the figure refers to the direction toward the left end, left side or first side edge of the lawn mower. The R direction refers to the direction toward the right end, right side or second side edge of the lawn mower. The A direction refers to the direction toward the front end, front side or third side edge of the lawn mower. The B direction refers to the direction toward the rear end, rear side or fourth side edge of the lawn mower. The U direction refers to the top, and the D direction refers to the bottom. The vertical direction and the thickness direction of the lawn mower are both the directions where D and U in the figure are located.

[0151] By not providing the protection mechanism 30 between the third side edge 13 and the cutting mechanism 20 , the structure of the lawn mower 100 can be simplified, thereby reducing the cost.

[0152] It should be noted that when the fuselage 10 is Figure 3 When the quadrilateral is shown in , the first side edge 11 and the second side edge 12 are two opposite side edges. Specifically, in the embodiment of the present application, the first side edge 11 and the second side edge 12 are the outer sides of the left and right sides of the fuselage 10, respectively. The third side edge 13 and the fourth side edge 14 are two side edges that are oppositely arranged at the front and rear ends of the fuselage 10, respectively. Specifically, in the embodiment of the present application, the third side edge 13 and the fourth side edge 14 are the outer sides of the front and rear sides of the fuselage 10, respectively.

[0153] In other embodiments, for example, when the fuselage 10 is a circular, arc-shaped or special-shaped structure, the first side edge 11 and the second side edge 12 are respectively partial side edges surrounding the front end and the rear end of the fuselage 10. The third side edge 13 is a side edge surrounding the front end of the fuselage 10, and the fourth side edge 14 is a partial side edge surrounding the rear end. In addition, when the fuselage 10 is circular, the first side edge 11, the second side edge 12, the third side edge 13 and the fourth side edge 14 can all be referred to as the outer side edges of the fuselage 10.

[0154] In a possible implementation, between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, between the third side edge 13 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20, only between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20 are provided with a protection mechanism 30. No protection mechanism 30 is provided between the fourth side edge 14 and the cutting mechanism 20.

[0155] By not providing the protection mechanism 30 between the fourth edge and the cutting mechanism 20, the structure of the lawn mower 100 can be further simplified and the cost can be further reduced.

[0156] In some embodiments, the number of the protection mechanisms 30 is two, wherein the two protection mechanisms 30 are relatively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20 .

[0157] In some other embodiments, the number of the protection mechanisms 30 may also be three, wherein the three protection mechanisms 30 are respectively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the third side edge 13 and the cutting mechanism 20. Alternatively, the three protection mechanisms 30 are respectively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20.

[0158] In the embodiment of the present application, the number of the protection mechanisms 30 is not further limited.

[0159] The specific structure of the cutting mechanism 20 is described in detail below.

[0160] Figure 4 A bottom view of a lawn mower 100 provided in an embodiment of the present application without the protection mechanism 30 is shown.

[0161] like Figure 4 As shown, the cutting mechanism 20 includes a cutter disc 21 and a blade 22 mounted on the cutter disc 21, and the output shaft is mounted in cooperation with the cutter disc 21 to drive the cutter disc 21 to rotate. In this embodiment, the rotation centerline of the cutting mechanism 20 is the rotation centerline of the cutter disc 21.

[0162] In this embodiment, there are three blades 22, and the three blades 22 are evenly installed on the cutter disc 21 along the circumferential direction of the cutter disc 21. Among them, one end of the blade 22 away from the center of the cutter disc 21 extends outside the cutter disc 21, so that the blade 22 can perform cutting operations.

[0163] It should be noted that the number of blades 22 can be selected as needed. For example, the number of blades 22 can be set to 1, 2, 3, 4 or more. In the implementation of the present application, the number of blades 22 is not limited.

[0164] In addition, the distribution of the blades 22 on the cutter disc 21 may also be uneven. As long as the cutting purpose can be achieved, the blades 22 can be arranged arbitrarily. In the embodiment of the present application, the setting position of the blades 22 is not further limited.

[0165] Exemplarily, a mounting position 23 for mounting the blade 22 is provided on the cutter disc 21 . The mounting position 23 may be an arc-shaped groove structure, and the blade 22 is fixed in the mounting position 23 by the fixing member 24 .

[0166] In this embodiment, the blade 22 can be rotatably mounted on the cutter disc 21 by means of mounting parts such as screws and rotating shafts. That is, the blade 22 can rotate freely and also rotates with the rotation of the cutter disc 21, so that the blade 22 has a certain degree of freedom. When encountering obstacles such as pebbles, the force between the blade 22 and the obstacles can be reduced, which can effectively protect the blade and prevent the blade from being damaged.

[0167] For example, in some other embodiments, the blade 22 can be set as a folding blade. When the blade 22 is not needed for mowing, the blade 22 can be folded so that the blade 22 is located inside the blade disc 21, that is, not exposed to the outer edge of the blade disc 21. When the blade 22 is needed for mowing, the blade 22 can be unfolded and the cutting surface of the blade 22 extends beyond the outer edge of the blade disc 21 to perform mowing. Of course, in other embodiments, the blade 22 can also be other structures, which will not be further described in the embodiments of the present application.

[0168] Of course, in other embodiments, the mounting position 23 may also be other structures, for example, a hole-shaped structure, the connecting member is a screw, etc., and the blade 22 is fixed to the mounting position 23 by the fixing member 24, so that the blade 22 is fixedly mounted on the blade disc 21. In the embodiment of the present application, the structure of the fixing member 24 and the mounting position 23 is not further limited.

[0169] In a possible implementation, the cutting width of the cutting mechanism 20 is 260 mm to 300 mm, that is, the cutting width generated by the blade 22 cooperating with the blade disc 21 to rotate. Since the blade 22 is generally circular when rotating, the cutting width can be the diameter of the circle. In addition, since the blade 22 can be set to different sizes, the cutting width also varies. In other embodiments, the cutting width can be greater than 300 mm or less than 260 mm. In the embodiment of the present application, the cutting width of the cutting mechanism 20 is not further limited.

[0170] By setting the cutting width of the cutting mechanism 20 to 260 mm to 300 mm, the size of the cutting mechanism 20 can be enlarged, thereby expanding the mowing area of ​​the lawn mower 100 and improving the mowing efficiency.

[0171] In one possible implementation, Figure 4 As shown, in the first direction, the distance between the outer edge of the cutting mechanism 20 and the first side edge 11 of the fuselage 10 is a first distance L1, and the distance between the outer edge of the cutting mechanism 20 and the second side edge 12 of the fuselage 10 is a second distance L2. In the second direction (Q direction), the distance between the outer edge of the cutting mechanism 20 and the third side edge 13 of the fuselage 10 is a third distance L3. The third distance L3 is greater than the first distance L1, and greater than the second distance L2. In this way, the distance between the cutting mechanism 20 and the third side edge 13 of the fuselage 10 can be ensured to be large, thereby ensuring that the safety performance at the third side edge 13 of the fuselage 10 is high.

[0172] It should be noted that the first side edge 11 and the second side edge 12 of the fuselage 10 refer to the edges of the fuselage 10 that are located outside the fuselage 10 in the first direction and are closest to the outer edge of the cutting mechanism 20 .

[0173] In a possible implementation, in the second direction (Q direction), the distance between the outer edge of the cutting mechanism 20 and the fourth side edge 14 of the fuselage 10 is a fourth distance L4. The fourth distance is greater than the first distance L1, and greater than the second distance L2. In this way, the distance between the cutting mechanism 20 and the fourth side edge 14 of the fuselage 10 can be ensured to be large, thereby ensuring a high safety performance at the fourth side edge 14 of the fuselage 10.

[0174] It should be noted that the outer edge of the cutting mechanism 20 refers to the outer edge of the cutting mechanism 20 at the maximum size. Figure 4 As shown in the circular dotted frame in FIG. 1 , for example, when the blade 22 rotates to face the third side edge 13 of the body 10, the third distance L3 is the distance from the end of the blade 22 away from the blade disc 21 to the third side edge 13. When the blade 22 rotates to face the fourth side edge 14 of the body 10, the fourth distance L4 is the distance from the end of the blade 22 away from the blade disc 21 to the fourth side edge 14.

[0175] The protection mechanism 30 will be described in detail below with reference to the accompanying drawings.

[0176] Figure 5 A schematic structural diagram of a protection mechanism 30 and a cutting mechanism 20 of a lawn mower 100 provided in an embodiment of the present application. Figure 6 A schematic structural diagram of a protection mechanism 30 and a cutting mechanism 20 of a lawn mower 100 provided in an embodiment of the present application. Figure 7 A side view of a protection mechanism 30 and a cutting mechanism 20 of a lawn mower 100 provided in an embodiment of the present application.

[0177] Combination Figure 4 and Figure 5 As shown, a protection mechanism 30 is provided between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20 .

[0178] Exemplarily, the protection mechanism 30 located between the first side edge 11 and the cutting mechanism 20 is referred to as the first protection mechanism 30a, and the protection mechanism 30 located between the second side edge 12 and the cutting mechanism 20 is referred to as the second protection mechanism 30b. The first protection mechanism 30a and the second protection mechanism 30b are relatively arranged on both sides of the cutting mechanism 20, and the structures of the first protection mechanism 30a and the second protection mechanism 30b can be the same. Of course, in other embodiments, the structures of the first protection mechanism 30a and the second protection mechanism 30b can also be different.

[0179] The following description will be made by taking the first protection mechanism 30a and the second protection mechanism 30b having the same structure as an example.

[0180] In a possible implementation, the first protection mechanism 30a may include a first protection portion 32 and a second protection portion 33. The first protection portion 32 is disposed between the first side edge 11 and the cutting mechanism 20, so that the first protection portion 32 of the first protection mechanism 30a can establish a protection barrier between the cutting mechanism 20 and the first side edge 11. At least part of the structure of the second protection portion 33 of the first protection mechanism 30a is disposed below the cutting mechanism 20, and the second protection portion 33 of the first protection mechanism 30a is used to establish a protection barrier below the cutting mechanism 20.

[0181] By configuring the first protection mechanism 30 a to include the first protection portion 32 and the second protection portion 33 , different positions of the first protection mechanism 30 a can form protection barriers at different positions of the lawn mower 100 , thereby improving the safety of the lawn mower 100 .

[0182] The second protection mechanism 30b may include a first protection portion 32 and a second protection portion 33. The first protection portion 32 of the second protection mechanism 30b is disposed between the second side edge 12 and the cutting mechanism 20, so that the first protection portion 32 of the second protection mechanism 30b can establish a protection barrier between the cutting mechanism 20 and the second side edge 12. At least part of the structure of the second protection portion 33 of the second protection mechanism 30b is disposed below the cutting mechanism 20, and the second protection portion 33 of the second protection mechanism 30b is used to establish a protection barrier below the cutting mechanism 20.

[0183] By configuring the second protection mechanism 30 b to include the first protection portion 32 and the second protection portion 33 , different positions of the second protection mechanism 30 b can form protection barriers at different positions of the lawn mower 100 , thereby improving the safety of the lawn mower 100 .

[0184] Continue to see Figure 5 As shown, the protection mechanism 30 may further include a mounting portion 31, wherein the mounting portion 31 is used to fix the protection mechanism 30 to the fuselage 10. Exemplarily, the first protection portion 32 may be connected to the mounting portion 31. The second protection portion 33 may also be connected to the mounting portion 31. Of course, in some other embodiments, the second protection portion 33 may also be connected to the first protection portion 32 (see Fig.11 shown).

[0185] Exemplarily, the mounting portion 31, the first protection portion 32, and the second protection portion 33 can be fixedly connected or detachably connected by welding, riveting, clamping, integral molding, etc. In the embodiment of the present application, the connection method between the mounting portion 31, the first protection portion 32, and the second protection portion 33 is not further limited.

[0186] The mounting portion 31 is provided to connect the first guard portion 32 and the second guard portion 33 to the body 10 , and to improve the connection stability between the first guard portion 32 and the second guard portion 33 and the body 10 , thereby improving the service life of the lawn mower 100 .

[0187] Exemplarily, the mounting portion 31 may be a plate-like structure, and a mounting hole 311 for connecting to the body 10 is provided on the mounting portion 31, and the body 10 and the mounting portion 31 may be connected by screws. Of course, in other embodiments, the body 10 and the mounting portion 31 may also be connected by snapping, that is, a snap buckle may be provided under the body 10, and the mounting portion 31 may be snapped into the snap buckle. In the embodiment of the present application, the connection method between the body 10 and the mounting portion 31 is not further limited.

[0188] In a possible implementation, the first protective portion 32 may be plate-shaped. Exemplarily, the first protective portion 32 may be disposed at one end of the mounting portion 31 away from the center of the cutter disc 21, and one end of the first protective portion 32 is connected to the mounting portion 31, and the other end extends to the side away from the fuselage 10 to the bottom of the cutter disc 21, so that the first protective portion 32 can establish a protective barrier on the side of the cutting mechanism 20. The first protective portion 32 and the mounting portion 31 may be formed by bending a plate 90° or other angles. In other embodiments, the first protective portion 32 may also be other shapes.

[0189] It should be noted that if Figure 5 As shown in FIG. 1 , the length of the first guard portion 32 in the forward direction (Q direction) of the lawn mower 100 may be smaller than that of the second guard portion 33. Of course, in other embodiments, such as Figure 6 As shown, the length of the first guard portion 32 in the forward direction of the lawn mower 100 may be greater than or equal to the second guard portion 33 , which may expand the protection area of ​​the first guard portion 32 , thereby improving the safety performance of the lawn mower 100 .

[0190] By setting the first protection part 32 in a plate shape, the structure of the first protection part 32 can be simplified, so that the first protection part 32 can form a protection barrier at the first side edge 11 and the second side edge 12 of the body 10. In addition, the plate-shaped structure has good blocking performance, which can prevent objects from contacting the cutting mechanism 20 from the first side edge 11 and the second side edge 12 of the body 10, thereby improving the safety of the lawn mower 100.

[0191] like Figure 7As shown, in the vertical direction, one end of the second protective portion 33 facing the fuselage 10 is connected to the mounting portion 31. One end of the second protective portion 33 facing away from the fuselage 10 is located below the cutting mechanism 20. By arranging the end of the second protective portion 33 facing away from the fuselage 10 to be located below the cutting mechanism 20, the second protective portion 33 can establish a protective barrier below the cutting mechanism 20.

[0192] It should be noted that in the embodiment of the present application, the vertical direction refers to the thickness direction of the lawn mower, that is, the up-down direction in the figure. In the embodiment of the present application, the bottom refers to the direction closer to the grass in the vertical direction when the lawn mower is in use.

[0193] Continue to see Figure 5 and Figure 6 As shown, at least one end of the second protection portion 33 along the forward direction of the lawn mower 100 is provided with at least one grass inlet 34 .

[0194] By providing a grass inlet 34 at at least one end of the second protection portion 33, when the lawn mower 100 is used to mow grass, the grass can contact the cutting mechanism 20 through the grass inlet 34 and then be cut by the cutting mechanism 20, thereby achieving the purpose of mowing grass.

[0195] In a possible implementation, the second protection portion 33 may include at least two strips 331, and the at least two strips 331 are respectively installed in cooperation with the mounting portion 31. The at least two strips 331 are arranged at intervals in the first direction. The gap between adjacent strips 331 forms a grass inlet 34.

[0196] In this embodiment, each strip 331 is arranged along the forward direction of the lawn mower 100, that is, each strip 331 is parallel to the forward direction, and all the strips 331 are arranged parallel to each other, and the gaps between the strips 331 form the grass inlet 34. In other embodiments, the strips 331 can also be arranged at a certain angle with the forward direction of the lawn mower 100, which can be an angle of 10 to 40 degrees.

[0197] By configuring the second protection part 33 to include at least two strips 331, the structure of the second protection part 33 can be simplified, making it easier to process and install, thereby reducing costs. Furthermore, the strips 331 are arranged at intervals to directly form a grass inlet 34 without the need to configure a specific grass inlet 34, thereby simplifying the structure of the second protection part 33 and reducing costs.

[0198] Exemplarily, the second protective portion 33 may include 2, 3, 4, or 5 strips 331, which may be specifically set according to the size of the cutting mechanism 20. In the embodiment of the present application, the number of the strips 331 in the second protective portion 33 is not further limited.

[0199] In the application embodiment, the strip 331 may be cylindrical. Of course, in other embodiments, the strip 331 may also be set to be a prism or other shapes, etc. In the embodiment of the present application, the specific shape of the strip 331 is not further limited.

[0200] By setting the strip 331 to be cylindrical, the processing difficulty of the strip 331 can be reduced, thereby reducing the cost. In addition, the cylindrical structure has a smooth surface, without sharp corners, etc., which will not accidentally scratch the user, and has a higher safety performance. It is easier to enter the grass and is not easy to get stuck in the grass.

[0201] It should be noted that, in the embodiment of the present application, the spacing distance between two adjacent strip-shaped members 331 is not further limited in the embodiment of the present application. In addition, the sizes of the multiple strip-shaped members 331 may be the same or different.

[0202] like Figure 5 As shown, in the direction from the outside to the inside of the cutting mechanism 20, the size of the strip 331 gradually increases, so that a plurality of strips 331 can be located outside the cutting mechanism 20. Thus, a protective barrier is formed outside the cutting mechanism 20.

[0203] Of course, in other embodiments, multiple strips 331 may be arranged to Figure 5 The lengths of the largest strips 331 are the same, so that the plurality of strips 331 can be located outside the cutting mechanism 20. In the embodiment of the present application, the size of the strips 331 is not further limited in the embodiment of the present application.

[0204] Continue to see Figure 5 As shown, in the second direction (Q direction), at least one end of each strip member 331 is provided with a bending portion, and the bending portion is bent toward the mounting portion 31. Among them, at least one bending portion on each strip member 331 is connected to the mounting portion 31.

[0205] By providing a bending portion on the strip 331, the strip 331 is connected to the mounting portion 31, thereby improving the connection stability between the second protection portion 33 and the mounting portion 31. In addition, by providing the bending portion, part of the structure of the strip 331 can be located below the cutting mechanism 20, and another part of the structure of the strip 331 is connected to the mounting portion 31, so that the second protection portion 33 can establish a protection barrier below the cutting mechanism 20.

[0206] For example, Figure 5 and Figure 6As shown, both ends of the strip 331 may be provided with a bending portion. The bending portion of each strip 331 is connected to the mounting portion 31. The middle portion 3312 is between the two bending portions 3311. An accommodating area for accommodating part of the cutter disc 21 is formed between the strip 331, the mounting portion 31 and the first protective portion 32. In the direction from the outside to the inside of the cutting mechanism 20, the length of the middle portion 3312 gradually increases, so that the accommodating area also gradually increases in the direction from the outside to the inside of the cutting mechanism 20 to match the circular contour of the cutter disc 21. Prevent the cutting mechanism 20 from interfering with the protective mechanism 30.

[0207] By providing bending portions at both ends of the strip 331 , the connection stability between the second protection portion 33 and the mounting portion 31 can be improved, thereby increasing the service life of the second protection portion 33 .

[0208] Exemplarily, the outer end of each bending portion 3311 is detachably mounted on the mounting portion 31 or formed integrally therewith, and the gaps between the bending portions 3311 at both ends of each strip member 331 are all for grass to pass through, and there is no obstacle for grass to come out from both sides.

[0209] In other embodiments, Figure 8 As shown, one end of the strip 331 is provided with a bending portion, wherein the end with the bending portion can be the end of the strip 331 facing the third side edge 13 of the fuselage 10, or can be the end of the strip 331 facing the fourth side edge 14 of the fuselage 10.

[0210] By providing a bent portion at one end of the strip 331 close to the third side edge 13 of the body 10 , the connection stability between the strip 331 and the mounting portion 31 can be improved.

[0211] By providing a bending portion at one end of each strip 331 close to the fourth side edge 14 of the body 10, the obstruction of the second protective portion 33 in the forward direction of the lawn mower 100 can be reduced, making it easier for grass to enter from the grass inlet 34 and contact the cutting mechanism 20, thereby improving the efficiency of the lawn mower 100.

[0212] In some other embodiments, a portion of the plurality of strips 331 is provided with a bent portion at one end facing the third side edge 13 of the body 10, and another portion of the plurality of strips 331 is provided with a bent portion at one end facing the fourth side edge 14 of the body 10. For example, the strips 331 provided with a bent portion at one end facing the third side edge 13 of the body 10 and the strips 331 provided with a bent portion at one end facing the fourth side edge 14 of the body 10 can be arranged alternately. This also enlarges the grass inlet 34, which can reduce the obstruction of the second protective part 33 in the forward direction of the lawn mower 100, facilitates the grass to enter from the grass inlet 34 and contact with the cutting mechanism 20, and can improve the efficiency of the lawn mower 100.

[0213] It should be noted that in the embodiment of the present application, the number and setting positions of the bending portions on each strip member 331 are not further limited.

[0214] like Fig. 9 As shown, in some embodiments, the second protection portion 33 further includes a connecting portion 3313. When a bending portion is provided at one end of each strip 331 close to the third side edge 13 of the fuselage 10, one end of each strip 331 close to the fourth side edge 14 of the fuselage 10 is connected to the connecting portion 3313. Exemplarily, the connecting portion 3313 may be a plate-like structure, which connects the ends of the plurality of strips 331 toward the fourth side edge 14 to improve the structural stability of the second protection portion 33.

[0215] By providing a bending portion 3311 on the strip 331, the strip 331 is formed into an "L" shape, so that a certain distance is formed between the middle portion 3312 of the strip 331 and the mounting portion 31, and the bending portion 3311 forms a receiving area for receiving part of the blade disc 21 between the strip 331, the mounting portion 31 and the first protective portion 32. The length of each strip 331 (specifically, the length of the middle portion 3312) gradually increases from the outside to the inside of the cutting mechanism 20, so that the width of the receiving area in the forward direction of the lawn mower 100 also gradually increases from the outside to the inside of the cutting mechanism 20 to match the circular contour of the blade disc 21, and the cutting width is not affected by the receiving area. At the same time, the bending portion 3311 also establishes a protective barrier on the side of the blade disc 21 close to the front end of the fuselage 10.

[0216] It should be noted that the mounting portion 31 of the first protection mechanism 30a and the mounting portion 31 of the second protection mechanism 30b in the above embodiment are separately arranged. Fig.10 As shown, the mounting parts 31 of the first protective mechanism 30a and the second protective mechanism 30b may also be arranged as a whole, so that the position of the mounting part 31 for connecting with the fuselage 10 can be increased, thereby improving the connection stability between the protective mechanism 30 and the fuselage 10.

[0217] Of course, in other embodiments, the protection mechanism 30 may also be other structures. For example, the protection mechanism 30 may be set as an integrated structure, such as Fig.11 As shown, the second guarding portion 33 includes a plate-like structure, and the second guarding portion 33 is arranged at an end of the first guarding portion 32 away from the fuselage 10 , wherein in a first direction, the second guarding portion 33 extends from the outer edge of the cutting mechanism 20 to the center of the cutting mechanism 20 .

[0218] In this embodiment, the mounting portion 31, the first protection portion 32 and the second protection portion 33 are integrally formed, and the mounting portion 31, the second protection portion 33 and the first protection portion 32 can be formed by bending a plate twice, and the mounting portion 31, the second protection portion 33 and the first protection portion 32 are in a U-shaped structure. Fig.12 As shown, the opening of the U-shaped structure faces the center of the blade disc 21, and the area enclosed by the mounting portion 31, the second protective portion 33 and the first protective portion 32 can accommodate part of the blade disc 21. Grass inlets 34 are provided at both ends of the second protective portion 33. Alternatively, in the second direction (Q direction), at least one grass inlet 34 is provided at both ends of the second protective portion 33.

[0219] By setting the protection mechanism 30 as an integrated structure, it is convenient to process, and the structural strength of the protection mechanism 30 can be improved, thereby increasing the service life of the protection mechanism 30. In addition, the second protection part 33 is set as a plate-like structure, and one end is connected to the first protection part 32, so that the obstruction of the second protection part 33 in the second direction (Q direction) can be reduced, which facilitates grass feeding and improves mowing efficiency.

[0220] Exemplarily, a plurality of grass inlets 34 are provided at one end of the second protective portion 33 close to the front end of the fuselage 10 (the third side edge 13). Two or more grass inlets 34 may be provided as needed, and grass may be fed in through the grass inlets 34 for cutting.

[0221] By arranging the grass inlet 34 at one end of the second guard portion 33 facing the third side edge 13, the grass can be conveniently contacted with the cutting mechanism 20 through the grass inlet 34 and then cut by the cutting mechanism 20 during the forward movement of the lawn mower 100, thereby achieving the purpose of mowing. By arranging the second guard portion 33 at one end of the first guard portion 32 away from the body 10, the first guard portion 32 and the second guard portion 33 can be connected without connecting the second guard portion 33 to the mounting portion 31, thereby simplifying the structure of the mounting portion 31 and reducing the cost.

[0222] Of course, in other embodiments, grass inlets 34 may be provided at both ends of the second protection portion 33 near the front and rear ends of the fuselage 10. In the embodiment of the present application, the location and number of the grass inlets 34 are not further limited.

[0223] By providing a plurality of grass inlets 34 at both ends of the second protection portion 33, when the lawn mower 100 is moving forward or backward, the grass can be easily contacted with the cutting mechanism 20 through the grass inlets 34 and then cut by the cutting mechanism 20, thereby achieving the purpose of mowing. In addition, when the lawn mower 100 is moving forward, the grass inlet 34 facing the fourth side edge 14 of the body 10 can be used as a grass discharge port, that is, the grass cut by the cutting mechanism 20 can be discharged through the grass inlet 34 facing the fourth side edge 14 of the body 10, so as to prevent the cutting mechanism 20 from being stuck.

[0224] In addition, the grass inlet 34 extends from the end of the second guarding portion 33 along the second direction, in a direction away from the end of the second guarding portion 33, so that during cutting operations, grass can enter the second guarding portion 33 from the grass inlet 34. This can make the grass entering from the grass inlet 34 closer to the cutting mechanism 20, thereby improving the cutting efficiency of the lawn mower 100.

[0225] In a possible implementation, a guide plate 35 is provided at the grass inlet 34. The guide plate 35 extends toward the body 10. By providing the guide plate 35, grass that is partially bent or lying on the ground can be guided into the grass inlet 34 through the guide plate 35, and the grass that is bent or lying on the ground can be supported so as to be cut by the cutting mechanism 20, thereby improving the cutting efficiency.

[0226] Of course, in other embodiments, the protection mechanism 30 may also be set to other structures, which will not be further explained in the embodiments of the present application.

[0227] The present application also provides a lawn mower 100, such as Fig.13 As shown, the lawn mower 100 includes a body 10 , wherein the body 10 has a first side edge 11 and a second side edge 12 arranged opposite to each other along a first direction, and the first direction intersects with a forward direction of the lawn mower 100 .

[0228] For example, the first direction may be perpendicular to the forward direction of the lawn mower 100, or the first direction may be set at an angle to the forward direction of the lawn mower 100, for example, 85°, 86°, etc. In the embodiment of the present application, the angle between the first direction and the forward direction of the lawn mower 100 is not further limited.

[0229] By setting the first direction perpendicular to the forward direction of the lawn mower 100, the safety performance of the lawn mower 100 can be improved. For example, when the two ends located in the forward direction of the lawn mower 100 are the front end and the rear end of the lawn mower 100, respectively, the first direction is set perpendicular to the forward direction of the lawn mower 100, and the first side edge 11 and the second side edge 12 of the body 10 are the left and right sides of the lawn mower 100, so that there can be protective barriers on both the left and right sides of the lawn mower 100, thereby improving the safety performance of the lawn mower 100.

[0230] like Fig.13 As shown, the lawn mower 100 may further include a cutting mechanism 20, wherein the cutting mechanism 20 is located below the body 10 and is used to perform cutting operations.

[0231] Exemplarily, an output shaft (not shown in the figure) may be provided on the fuselage 10, and the output shaft is installed in cooperation with the cutting mechanism, wherein the output shaft is used to drive the cutting mechanism to rotate so that the cutting mechanism can perform a cutting operation.

[0232] Exemplarily, the rotation centerline of the cutting mechanism 20 coincides with the axis of the output shaft. A control device may be provided on the fuselage 10, and the control device is used to drive the output shaft to rotate, and the output shaft rotates to drive the rotating structure to rotate, so that the rotating structure can perform cutting operations.

[0233] In some embodiments, the control device may be a motor, etc. In the embodiments of the present application, the specific structure of the control device is not further limited.

[0234] In a possible implementation, in the first direction, the cutting mechanism 20 may be located in the middle of the fuselage 10. By arranging the cutting mechanism 20 in the middle of the fuselage 10, the distances from the cutting mechanism 20 to the first side edge 11 and the second side edge 12 can be the same, so that when the lawn mower 100 is in operation, the force positions of the first side edge 11 and the second side edge 12 of the fuselage 10 are symmetrical, so that the fuselage 10 is easier to maintain balance and is not easy to tip over.

[0235] In this embodiment of the present application, in the first direction, the distance between the outer edge of the cutting mechanism 20 and the first side edge 11 of the fuselage 10 is a first distance H1, and the distance between the outer edge of the cutting mechanism 20 and the second side edge 12 of the fuselage 10 is a second distance H2. The first distance H1 and / or the second distance H2 is less than 50 mm.

[0236] By setting the first distance H1 and / or the second distance H2 to be less than 50 mm, the distance from the cutting mechanism 20 to the outside of the body 10 can be kept small, which is beneficial for the lawn mower 100 to be closer to the edge of the grass being cut, reducing the scope of manual trimming, thereby improving the automation of the smart lawn mower 100.

[0237] Exemplarily, when the cutting mechanism 20 is located in the middle of the fuselage 10, the first distance H1 is equal to the second distance H2. That is, the first distance H1 and the second distance H2 are both set to be less than 50 mm.

[0238] Of course, in other embodiments, when the cutting mechanism 20 is located outside the middle of the body 10, the first distance H1 and the second distance H2 are different. For example, the first distance H1 can be set to be smaller than the second distance H2, or the first distance H1 can be set to be larger than the second distance H2. In this case, the first distance H1 and / or the second distance H2 can be set to be less than 50 mm, so that the outer edge of the cutting mechanism 20 of the lawn mower 100 at least located at the first side edge 11 or the second side edge 12 can be less than 50 mm from the outer edge of the body 10, thereby achieving the technical effect that the lawn mower 100 can cut to the edge. In the embodiment of the present application, the quantitative relationship between the first distance H1 and the second distance H2 is not further limited, and can be set specifically according to needs.

[0239] It should be noted that the first side edge 11 and the second side edge 12 of the body 10 refer to edge positions located outside the body 10 in the first direction.

[0240] It should be noted that in the embodiment of the present application, the lawn mower 100 may further include a driving wheel 40 and a driven wheel 50. The driving wheel 40 is mounted at the rear end of the body 10, and the driven wheel 50 is mounted at the front end of the body 10, or the driving wheel 40 may be mounted at the front end of the body 10, and the driven wheel 50 is mounted at the rear end of the body 10.

[0241] like Fig.13 As shown, two driving wheels 40 are respectively installed on the inner side of the rear end of the body 10, and the driving wheels 40 are driven by the motor on the body 10, that is, the lawn mower 100 is a rear-drive lawn mower 100, and the driven wheel 50 is installed on the inner side of the front end of the body 10, and the driven wheel 50 is preferably a universal wheel. By arranging the driving wheel 40 and the driven wheel 50, the lawn mower 100 can move and turn.

[0242] There are two driving wheels 40 and two driven wheels 50. In other embodiments, only one driven wheel 50 may be provided, or the number of driven wheels 50 may be increased as needed, and the number of driving wheels 40 may be increased or decreased as needed. In the embodiment of the present application, the number of driving wheels 40 and driven wheels 50 is not further limited.

[0243] Exemplarily, the direction from the driving wheel 40 to the driven wheel 50 is the forward direction of the lawn mower 100. By arranging the driving wheel 40 on the inner side of the rear end of the body 10, the distance from the outer edge of the cutting mechanism 20 to the first side edge 11 and the second side edge 12 of the body 10 can be reduced so that the lawn mower 100 can cut the edge of the grass.

[0244] In a possible implementation, the first distance H1 and / or the second distance H2 is less than 45 mm.

[0245] By making the first distance H1 and / or the second distance H2 less than 45 mm, the distance from the cutting mechanism 20 to the outside of the body 10 can be further shortened, which is more conducive to the lawn mower 100 being closer to the edge of the grass being cut, reducing the scope of manual trimming, thereby improving the automation of the smart lawn mower 100.

[0246] In a possible implementation, the first distance H1 and / or the second distance H2 is less than 40 mm.

[0247] By making the first distance H1 and / or the second distance H2 less than 40 mm, the distance from the cutting mechanism 20 to the outside of the body 10 can be further shortened, which is more conducive to the lawn mower 100 being closer to the edge of the grass being cut, reducing the scope of manual trimming, thereby improving the automation of the smart lawn mower 100.

[0248] Exemplarily, the first distance H1 and the second distance H2 are equal, and the first distance H1 and the second distance H2 may both be 35mm, 36mm, 37mm, 38mm, 39mm, 40mm, 41mm, 42mm, 43mm, 44mm, 45mm, 46mm, 47mm, 48mm, 49mm, 50mm, etc.

[0249] In the embodiment of the present application, the specific values ​​of the first distance H1 and the second distance H2 are not further limited.

[0250] In a possible implementation, the lawn mower 100 also includes a protective mechanism 30, which is arranged below the body 10. The protective mechanism 30 is provided between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20. The protective mechanism 30 is used to establish a protective barrier at the first side edge 11, the second side edge 12 and below the body 10.

[0251] By arranging the protection mechanism 30 between the cutting mechanism 20 and the first side edge 11 of the fuselage 10 and between the cutting mechanism 20 and the second side edge 12 of the fuselage 10, and arranging the protection mechanism 30 so as to establish a protection barrier between the first side edge 11, the second side edge 12 and the bottom of the fuselage 10, the safety performance of the lawn mower 100 can be improved.

[0252] In a possible implementation, the body 10 has a third side edge 13 and a fourth side edge 14 arranged opposite to each other along a second direction, and the second direction is the forward direction of the lawn mower 100. Among them, between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, between the third side edge 13 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20, only between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20 are provided with a protection mechanism 30. No protection mechanism 30 is provided between the third side edge 13 and the cutting mechanism 20.

[0253] It should be noted that, for the convenience of description, the Q direction in the figure represents the forward direction of the lawn mower, that is, the second direction. The L direction in the figure refers to the direction toward the left end, left side or first side edge of the lawn mower. The R direction refers to the direction toward the right end, right side or second side edge of the lawn mower. The A direction refers to the direction toward the front end, front side or third side edge of the lawn mower. The B direction refers to the direction toward the rear end, rear side or fourth side edge of the lawn mower. The U direction refers to the top, and the D direction refers to the bottom. The vertical direction and the thickness direction of the lawn mower are both the directions where D and U in the figure are located.

[0254] By not providing the protection mechanism 30 between the third side edge 13 and the cutting mechanism 20 , the structure of the lawn mower 100 can be simplified, thereby reducing the cost.

[0255] It should be noted that when the fuselage 10 is Fig.13 When the quadrilateral is shown in , the first side edge 11 and the second side edge 12 are two opposite side edges. Specifically, in the embodiment of the present application, the first side edge 11 and the second side edge 12 are the outer sides of the left and right sides of the fuselage 10, respectively. The third side edge 13 and the fourth side edge 14 are two side edges that are oppositely arranged at the front and rear ends of the fuselage 10, respectively. Specifically, in the embodiment of the present application, the third side edge 13 and the fourth side edge 14 are the outer sides of the front and rear sides of the fuselage 10, respectively.

[0256] In other embodiments, for example, when the fuselage 10 is a circular, arc-shaped or special-shaped structure, the first side edge 11 and the second side edge 12 are respectively partial side edges surrounding the front end and the rear end of the fuselage 10. The third side edge 13 is a side edge surrounding the front end of the fuselage 10, and the fourth side edge 14 is a partial side edge surrounding the rear end. In addition, when the fuselage 10 is circular, the first side edge 11, the second side edge 12, the third side edge 13 and the fourth side edge 14 can all be referred to as the outer side edges of the fuselage 10.

[0257] In a possible implementation, between the first side edge 11 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, between the third side edge 13 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20, only between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20 are provided with a protection mechanism 30. No protection mechanism 30 is provided between the fourth side edge 14 and the cutting mechanism 20.

[0258] By not providing the protection mechanism 30 between the fourth edge and the cutting mechanism 20, the structure of the lawn mower 100 can be further simplified and the cost can be further reduced.

[0259] In some embodiments, the number of the protection mechanisms 30 is two, wherein the two protection mechanisms 30 are relatively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20 .

[0260] In some other embodiments, the number of the protection mechanisms 30 may also be three, wherein the three protection mechanisms 30 are respectively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the third side edge 13 and the cutting mechanism 20. Alternatively, the three protection mechanisms 30 are respectively arranged between the first side edge 11 of the fuselage 10 and the cutting mechanism 20, between the second side edge 12 and the cutting mechanism 20, and between the fourth side edge 14 and the cutting mechanism 20.

[0261] In the embodiment of the present application, the number of the protection mechanisms 30 is not further limited.

[0262] The specific structure of the cutting mechanism 20 is described in detail below.

[0263] Fig.14 A bottom view of a lawn mower 100 provided in an embodiment of the present application without the protection mechanism 30 is shown.

[0264] like Fig.14As shown, the cutting mechanism 20 includes a cutter disc 21 and a blade 22 mounted on the cutter disc 21, and the output shaft is mounted in cooperation with the cutter disc 21 to drive the cutter disc 21 to rotate. In this embodiment, the rotation centerline of the cutting mechanism 20 is the rotation centerline of the cutter disc 21.

[0265] In this embodiment, there are three blades 22, and the three blades 22 are evenly installed on the cutter disc 21 along the circumferential direction of the cutter disc 21. Among them, one end of the blade 22 away from the center of the cutter disc 21 extends outside the cutter disc 21, so that the blade 22 can perform cutting operations.

[0266] It should be noted that the number of blades 22 can be selected as needed. For example, the number of blades 22 can be set to 1, 2, 3, 4 or more. In the implementation of the present application, the number of blades 22 is not limited.

[0267] In addition, the distribution of the blades 22 on the cutter disc 21 may also be uneven. As long as the cutting purpose can be achieved, the blades 22 can be arranged arbitrarily. In the embodiment of the present application, the setting position of the blades 22 is not further limited.

[0268] Exemplarily, a mounting position 23 for mounting the blade 22 is provided on the cutter disc 21 . The mounting position 23 may be an arc-shaped groove structure, and the blade 22 is fixed in the mounting position 23 by the fixing member 24 .

[0269] In this embodiment, the blade 22 can be rotatably mounted on the cutter disc 21 by means of mounting parts such as screws and rotating shafts. That is, the blade 22 can rotate freely and also rotates with the rotation of the cutter disc 21, so that the blade 22 has a certain degree of freedom. When encountering obstacles such as pebbles, the force between the blade 22 and the obstacles can be reduced, which can effectively protect the blade and prevent the blade from being damaged.

[0270] For example, in some other embodiments, the blade 22 can be set as a folding blade. When the blade 22 is not needed for mowing, the blade 22 can be folded so that the blade 22 is located inside the blade disc 21, that is, not exposed to the outer edge of the blade disc 21. When the blade 22 is needed for mowing, the blade 22 can be unfolded and the cutting surface of the blade 22 extends beyond the outer edge of the blade disc 21 to perform mowing. Of course, in other embodiments, the blade 22 can also be other structures, which will not be further described in the embodiments of the present application.

[0271] Of course, in other embodiments, the mounting position 23 may also be other structures, for example, a hole-shaped structure, the connecting member is a screw, etc., and the blade 22 is fixed to the mounting position 23 by the fixing member 24, so that the blade 22 is fixedly mounted on the blade disc 21. In the embodiment of the present application, the structure of the fixing member 24 and the mounting position 23 is not further limited.

[0272] In a possible implementation, the cutting width of the cutting mechanism 20 is 260 mm to 350 mm, that is, the cutting width generated by the blade 22 cooperating with the cutter disc 21 to rotate. Since the blade 22 is generally circular when rotating, the cutting width can be the diameter of the circle. Exemplarily, the diameter of the circle can be 260 mm, 280 mm, 300 mm, 320 mm, 340 mm, 350 mm, etc. In the embodiment of the present application, the cutting width is not further limited. In addition, since the blade 22 can be set to different sizes, the cutting width is also different. In other embodiments, the cutting width can be greater than 350 mm or less than 260 mm. In the embodiment of the present application, the cutting width of the cutting mechanism 20 is not further limited.

[0273] By setting the cutting width of the cutting mechanism 20 to 260 mm to 350 mm, the size of the cutting mechanism 20 can be enlarged, thereby expanding the mowing area of ​​the lawn mower 100 and improving the mowing efficiency.

[0274] In one possible implementation, Fig.14 As shown, in the first direction, the distance between the outer edge of the cutting mechanism 20 and the first side edge 11 of the fuselage 10 is a first distance H1, and the distance between the outer edge of the cutting mechanism 20 and the second side edge 12 of the fuselage 10 is a second distance H2. In the second direction, the distance between the outer edge of the cutting mechanism 20 and the third side edge 13 of the fuselage 10 is a third distance H3. The third distance H3 is greater than the first distance H1, and greater than the second distance H2. In this way, the distance between the cutting mechanism 20 and the third side edge 13 of the fuselage 10 can be ensured to be large, thereby ensuring that the safety performance at the third side edge 13 of the fuselage 10 is high.

[0275] In a possible implementation, in the second direction (Q direction), the distance between the outer edge of the cutting mechanism 20 and the fourth side edge 14 of the fuselage 10 is a fourth distance H4. The fourth distance is greater than the first distance H1, and greater than the second distance H2. In this way, the distance between the cutting mechanism 20 and the fourth side edge 14 of the fuselage 10 can be ensured to be large, thereby ensuring a high safety performance at the fourth side edge 14 of the fuselage 10.

[0276] It should be noted that the outer edge of the cutting mechanism 20 is the outer edge of the cutting mechanism 20 at the maximum size. Fig.14For example, when the blade 22 rotates to face the third side edge 13 of the body 10, the third distance H3 is the distance from the end of the blade 22 away from the blade disc 21 to the third side edge 13. When the blade 22 rotates to face the fourth side edge 14 of the body 10, the fourth distance H4 is the distance from the end of the blade 22 away from the blade disc 21 to the fourth side edge 14.
