[0001] This application is a divisional application of the original application with the application number 202323529824.1 and the original filing date of December 22, 2023, and the entire contents of the original application are incorporated herein by reference. TECHNICAL FIELD

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

[0003] With the development of automation technology and artificial intelligence, intelligent lawn mowers can automatically perform mowing tasks, greatly saving people's time and providing great convenience for life.

[0004] The intelligent lawn mowers on the market are generally designed with a small size cutter head due to safety regulations and energy consumption requirements, which makes the cutting width small and cannot cut the grass at the edge of the lawn, so the edge of the lawn needs to be manually trimmed, reducing the automation level of the intelligent lawn mower.

[0005] The information disclosed in this BACKGROUND section is only intended to increase an understanding of the general background of the present application and is not intended to be a recognition or any form of suggestion that this information forms prior art that is already known to those of ordinary skill in the art. SUMMARY

[0006] The embodiments of the present application provide a lawn mower which can increase the cutting width.

[0007] The first aspect of the present application provides a lawn mower, which comprises a machine body, the machine body having an output shaft, the machine body having a first side edge and a second side edge oppositely arranged along a first direction, the first direction intersecting the forward direction of the lawn mower. A cutting mechanism is located below the machine body and is installed in cooperation with the output shaft for performing cutting work under the driving of the output shaft. And a protection mechanism is arranged below the machine 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 embodiments 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 machine body and between the cutting mechanism and the second side edge of the machine body, and arranging the protection mechanism to protect the first side edge and the second side edge of the machine body and the lower part of the machine body. And under the premise of ensuring safety regulations, the size of the cutting mechanism can be increased, thereby obtaining a larger cutting width. So that the lawn mower can be closer to the edge of the cut grass, thereby having a larger cutting range, reducing the range of manual trimming, and thereby improving the automation of the intelligent lawn mower.

[0009] In a possible implementation, the fuselage has a third side edge and a fourth side edge oppositely arranged along a second direction, the second direction being a forward direction of the mower. The protection mechanism is not arranged between the third side edge and the cutting mechanism.

[0010] By not arranging the protection mechanism between the third side edge and the cutting mechanism, the structure of the mower can be simplified, and the cost can be reduced.

[0011] In a possible implementation, the protection mechanism is not arranged between the fourth side edge and the cutting mechanism.

[0012] By not arranging the protection mechanism between the fourth side edge and the cutting mechanism, the structure of the mower can be further simplified, and the cost can be further reduced.

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

[0014] By arranging the first direction to be perpendicular to the forward direction of the mower, the safety performance of the mower can be improved. For example, when two ends in the forward direction of the mower are a front end and a rear end of the mower respectively, the first direction is arranged to be perpendicular to the forward direction of the mower, and then the first side edge and the second side edge of the fuselage are the left side and the right side of the mower, so that the protection can be performed on the left side and the right side of the mower, and the safety performance of the mower can be improved.

[0015] In a possible implementation, in the first direction, a distance between an outer side edge of the cutting mechanism and the first side edge of the fuselage is a first distance, and a distance between the outer side edge of the cutting mechanism and the second side edge of the fuselage is a second distance. In the second direction, a distance between the outer side 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 arranging 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 large, and the safety performance of the third side edge of the fuselage can be high.

[0017] In a possible implementation, in the second direction, a distance between the outer side edge of the cutting mechanism and the fourth side edge of the fuselage is a fourth distance. The fourth distance 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, the distance between the cutting mechanism and the fourth side edge of the machine body is ensured to be large, thereby ensuring that the safety performance at the fourth side edge of the machine body is high.

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

[0020] By arranging the protection mechanism to include the first protection part and the second protection part, different positions of the protection mechanism can protect different directions of the lawn mower, thereby improving the safety of the lawn mower.

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

[0022] By arranging the first protection part to be in a plate shape, the structure of the first protection part can be simplified, so that the first protection 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 arranged at at least one end of the second protection part in the advancing direction of the lawn mower.

[0024] By arranging the grass inlet at at least one end of the second protection part, when the lawn mower is used to cut grass, the grass can be contacted with the cutting mechanism through the grass inlet, and then cut by the cutting mechanism, thereby achieving the purpose of cutting grass.

[0025] In a possible implementation, the machine body has a third side edge and a fourth side edge arranged opposite in a second direction, the second direction being the advancing 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 arranged at an end of the second protection part facing the third side edge. Alternatively, in the second direction, at least one grass inlet is arranged at both ends of the second protection part.

[0026] By setting the grass inlet at one end of the second protection part towards the third side edge, the grass can be conveniently contacted with the cutting mechanism through the grass inlet during the forward movement of the mower, and then cut by the cutting mechanism to achieve the purpose of mowing. By setting the grass inlet at both ends of the second protection part, the grass can be conveniently contacted with the cutting mechanism through the grass inlet during the forward and backward movement of the mower, and then cut by the cutting mechanism to achieve the purpose of mowing. In addition, when the mower moves forward, the grass inlet towards the fourth side edge of the machine body can be used as a grass outlet, that is, the grass cut by the cutting mechanism can be discharged through the grass inlet towards the fourth side edge of the machine body to prevent the cutting mechanism from being stuck.

[0027] In a possible implementation, the protection mechanism further comprises a mounting part connected with the machine body. The first protection part is connected with the mounting part, and the second protection part is connected with the mounting part or the first protection part.

[0030] By setting the other end of the second protection part away from the machine body to be located below the cutting mechanism, the second protection part can protect below the cutting mechanism.

[0031] In a possible implementation, the second protection part comprises at least two strip-shaped members, and the at least two strip-shaped members are respectively mounted in cooperation with the mounting part. The at least two strip-shaped members are spaced apart in the first direction. The gap between adjacent strip-shaped members forms the grass inlet.

[0032] By setting the second protection part as at least two strip-shaped members, the structure of the second protection part can be simplified, the processing and installation are facilitated, and the cost is reduced. In addition, the strip-shaped members are spaced apart, the grass inlet can be directly formed, and a specific grass inlet is not needed, so that the structure of the second protection part is simplified and the cost is reduced.

[0033] In a possible implementation, the machine body has a third side edge and a fourth side edge oppositely arranged along a second direction, and the second direction is the forward direction of the mower. At least one end of each strip-shaped member is provided with a bending part extending towards the mounting part in the second direction. At least one bending part on each strip-shaped member is connected with the mounting part.

[0034] The bending part is arranged on the strip-shaped part, so that the strip-shaped part is connected with the mounting part, thereby improving the connection stability of the second protection part and the mounting part.

[0035] In a possible implementation, each of the strip-shaped parts is provided with the bending part at one end close to the third side edge of the machine body, and each of the strip-shaped parts is connected with the mounting part through the bending part. Alternatively, each of the strip-shaped parts is provided with the bending part at one end close to the fourth side edge of the machine body, and each of the strip-shaped parts is connected with the mounting part through the bending part.

[0036] The bending part is arranged at one end of the strip-shaped part close to the third side edge of the machine body, so that the connection stability of the strip-shaped part and the mounting part is improved. The bending part is arranged at one end of each of the strip-shaped parts close to the fourth side edge of the machine body, so that the second protection part is less hindered in the forward direction of the mower, the grass is facilitated to enter the grass inlet and be in contact with the cutting mechanism, and the efficiency of the mower is improved.

[0037] In a possible implementation, the second protection part further comprises a connecting part. When each of the strip-shaped parts is provided with the bending part at one end close to the third side edge of the machine body, one end of each of the strip-shaped parts close to the fourth side edge of the machine body is connected with the connecting part.

[0038] The connecting part is arranged at one end of the second protection part without the bending part, so that the structural stability of the second protection part is improved.

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

[0040] Both ends of the strip-shaped part are provided with the bending part, so that the connection stability between the second protection part and the mounting part is improved, and the service life of the second protection part is improved.

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

[0042] The mounting part, the first protection part, and the second protection part are integrally formed, so that the structural strength of the protection mechanism is improved.

[0043] In a possible implementation, the strip-shaped part is in a cylindrical shape.

[0044] The strip-shaped part is in a cylindrical shape, so that the processing difficulty of the strip-shaped part is reduced, and the cost is reduced. In addition, the cylindrical structure has a smooth surface without sharp edges, so that the user is not accidentally scratched, and the safety performance is high.

[0045] In a possible implementation, the second protection part is arranged at an end of the first protection part away from the machine body. The second protection part comprises a plate structure, and in the first direction, the second protection part extends from an outer edge of the cutting mechanism to a center of the cutting mechanism.

[0046] By arranging the second protection part at an end of the first protection part away from the machine body, the first protection part and the second protection part can be connected without connecting the second protection part with the mounting part, so that the structure of the mounting part can be simplified, and the cost can be reduced. In addition, the protection mechanism can be made into one piece, so that the processing is facilitated, and the structural strength of the protection mechanism can be improved, and the service life of the protection mechanism can be improved. In addition, by arranging the second protection part to extend from the end of the first protection part away from the machine body to the direction close to the center axis of the cutting mechanism in the first direction, the second protection part in the second direction can be reduced, the grass can be facilitated, and the mowing efficiency can be improved.

[0047] In a possible implementation, a guide plate is arranged at the grass inlet. The guide plate extends towards the machine body.

[0048] By arranging the guide plate, the grass in the bent state or the fallen state can be guided into the grass inlet through the guide plate, and the cutting efficiency can be improved.

[0049] In a possible implementation, in the first direction, the cutting mechanism is located at the middle of the machine body.

[0050] By arranging the cutting mechanism at the middle of the machine body, the distance from the cutting mechanism to the first side edge and the second side edge can be the same, so that when the mower is working, the stress positions of the first side edge and the second side edge of the machine body are symmetrical, so that the machine body is more easily balanced and less likely to overturn.

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

[0052] By arranging the cutting width of the cutting mechanism to be 260mm-300mm, the size of the cutting mechanism can be expanded, and the mowing area of the mower can be expanded, and the mowing efficiency can be improved.

[0053] In a possible implementation, the mower comprises a driving wheel and a driven wheel. The driving wheel is arranged at the front end of the machine body, and the driven wheel is arranged at the rear end of the machine body.

[0054] By arranging the driving wheel and the driven wheel, the mower can move and turn.

[0055] In a second aspect, the application provides a mower, comprising a body having a first side edge and a second side edge oppositely arranged along a first direction intersecting a forward direction of the mower; and a cutting mechanism arranged below the body and configured to perform a cutting operation, wherein a distance between an outer side edge of the cutting mechanism and the first side edge of the body is a first distance, and a distance between the outer side 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, the distance between the cutting mechanism and the outer side of the body is small, which is beneficial for the mower to be closer to the edge of the cutting grass, reduces the range of manual pruning, and thus improves the automation of the intelligent mower. In addition, the width of the body of the mower is small, which can realize the miniaturization of the mower and reduce the cost. Furthermore, the small distance between the outer side edge of the cutting mechanism and the edge of the body can provide better visibility, so that the user can more clearly see the cutting mechanism and the edge of the lawn, and thus more accurately prune.

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

[0058] By setting the first distance and / or the second distance to be less than 45 mm, the distance between the cutting mechanism and the outer side of the body is further reduced, which is more beneficial for the mower to be closer to the edge of the cutting grass, reduces the range of manual pruning, and thus improves the automation of the intelligent mower.

[0134] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

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

[0136] Figure 1 A top view of the lawn mower provided by the embodiment of the present application is shown in FIG. 2. Figure 2 A side view of the lawn mower provided by the embodiment of the present application is shown in FIG. 3. Figure 3 A bottom view of the lawn mower provided by the embodiment of the present application is shown in FIG. 1.

[0137] The present application provides a lawn mower 100, as shown inFigure 1 As shown in the figure, the mower 100 can include a machine body 10, the machine body 10 has an output shaft (not shown in the figure), the machine body 10 has a first side edge 11 and a second side edge 12 which are oppositely arranged along a first direction, the first direction intersects with the advancing direction of the mower 100.

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

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

[0140] As shown in the figure, Figure 2 The mower 100 can further include a cutting mechanism 20, wherein the cutting mechanism 20 is located below the machine body 10 and is installed in cooperation with the output shaft, and is used to perform cutting work under the driving of the output shaft.

[0141] For example, the rotation center line of the cutting mechanism 20 coincides with the axis of the output shaft. The machine body 10 can be provided with a control device, 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 work.

[0142] In some embodiments, the control device can be a motor, and the specific structure of the control device is not limited further in the embodiment of the present application.

[0143] In a possible implementation, in the first direction, the cutting mechanism 20 can be located in the middle of the machine body 10. By arranging the cutting mechanism 20 in the middle of the machine body 10, the distance from the cutting mechanism 20 to the first side edge 11 and the second side edge 12 is the same, so that the force position of the first side edge 11 and the second side edge 12 of the machine body 10 is symmetrical when the mower 100 is working, so that the machine body 10 is easier to keep balance and is not easy to overturn.

[0144] As shown in the figure, Figure 3As shown, the mower 100 can further include a protection mechanism 30, which is arranged below the body 10, between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20, and is used to establish a protection barrier below the first side edge 11 and the second side edge 12 of the body 10.

[0145] The mower 100 in the embodiment of the present application can improve the safety performance of the mower 100 by arranging the protection mechanism 30 between the cutting mechanism 20 and the first side edge 11 of the body 10 and between the cutting mechanism 20 and the second side edge 12 of the body 10, and arranging the protection mechanism 30 to establish a protection barrier below the first side edge 11 and the second side edge 12 of the body 10. Moreover, the size of the cutting mechanism 20 can be increased under the premise of ensuring safety regulations, thereby obtaining a larger cutting width. The mower 100 can be closer to the edge of the grassland to be cut, thereby having a larger cutting range and reducing the range of manual pruning, thereby improving the automation of the intelligent mower 100.

[0146] The mower 100 in the embodiment of the present application can further include a driving wheel 40 and a driven wheel 50. The driving wheel 40 can be installed at the front end of the body 10, and the driven wheel 50 can be installed at the rear end of the body 10. Alternatively, the driving wheel 40 can be installed at the rear end of the body 10, and the driven wheel 50 can be installed at the front end of the body 10. Figure 3 As shown, the two driving wheels 40 are respectively installed at the outer sides of the front end of the body 10, and the two driving wheels 40 can also be respectively installed at the outer sides of the front end of the body 10. The driving wheels 40 are driven by the motor on the body 10, that is, the mower 100 is a front-drive type mower 100, and the driven wheel 50 is installed at the inner side of the rear end of the body 10, and the driven wheel 50 is preferably a universal wheel. The driving wheel 40 and the driven wheel 50 are arranged to enable the mower 100 to move and turn.

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

[0148] For example, the direction from the driven wheel 50 to the driving wheel 40 is the forward direction of the mower 100. By arranging the driving wheel 40 at the outer side of the front end of the body 10, sufficient space is left at the bottom of the front end of the body 10 to enter the grass, thereby avoiding the traditional arrangement of the driven wheel 50 at the bottom of the front end of the body 10, which causes the body 10 to be hindered by the cutting mechanism 20 behind when the body 10 advances due to the driven wheel 50 crushing the grass.

[0149] In a possible implementation, the machine body 10 has a third side edge 13 and a fourth side edge 14 arranged oppositely along a second direction, the second direction being a forward direction of the mower 100. In this case, no protection mechanism 30 is arranged 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 mower, that is, the second direction. The L direction in the figure refers to the direction towards the left end, left side or first side edge of the mower. The R direction refers to the direction towards the right end, right side or second side edge of the mower. The A direction refers to the direction towards the front end, front side or third side edge of the mower. The B direction refers to the direction towards the rear end, rear side or fourth side edge of the mower. The U direction refers to the upper direction, and the D direction refers to the lower direction. The vertical direction and the thickness direction of the mower are the directions of the D and U directions in the figure.

[0151] By arranging no protection mechanism 30 between the third side edge 13 and the cutting mechanism 20, the structure of the mower 100 can be simplified, and the cost can be reduced.

[0152] It should be noted that, when the machine body 10 is a quadrilateral as shown in Figure 3 In the embodiment of the present application, the first side edge 11 and the second side edge 12 are respectively the outer side edges of the left side and the right side of the machine body 10. The third side edge 13 and the fourth side edge 14 are respectively the two side edges arranged oppositely at the front end and the rear end of the machine body 10, and are respectively the outer side edges of the front side and the rear side of the machine body 10.

[0153] In other embodiments, for example, when the machine body 10 is a circular, arc-shaped or special-shaped structure, the first side edge 11 and the second side edge 12 are respectively the side edges around the part between the front end and the rear end of the machine body 10. The third side edge 13 is the side edge around the front end of the machine body 10, and the fourth side edge 14 is the side edge around the rear end of the machine body 10. In addition, when the machine body 10 is a circular structure, 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 machine body 10.

[0154] In a possible implementation, no protection mechanism 30 is arranged between the fourth side edge 14 and the cutting mechanism 20.

[0155] By arranging no protection mechanism 30 between the fourth side edge and the cutting mechanism 20, the structure of the mower 100 can be further simplified, and the cost can be further reduced.

[0156] In some embodiments, the number of protective mechanisms 30 is two, wherein the two protective mechanisms 30 are disposed opposite to each other between the first side edge 11 of the body 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 protective mechanisms 30 may also be three, wherein the three protective mechanisms 30 are respectively disposed between the first side edge 11 and the cutting mechanism 20, the second side edge 12 and the cutting mechanism 20, and the third side edge 13 and the cutting mechanism 20. Alternatively, the three protective mechanisms 30 are respectively disposed between the first side edge 11 and the cutting mechanism 20, the second side edge 12 and the cutting mechanism 20, and the fourth side edge 14 and the cutting mechanism 20.

[0158] In this embodiment, the number of protective mechanisms 30 is not further limited.

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

[0160] Figure 4 A bottom view of a lawnmower 100 removing the protective mechanism 30, provided for an embodiment of this application.

[0161] like Figure 4 As shown, the cutting mechanism 20 includes a cutter head 21 and blades 22 mounted on the cutter head 21. An output shaft is fitted to the cutter head 21 to drive the cutter head 21 to rotate. In this embodiment, the rotation center line of the cutting mechanism 20 is the rotation center line of the cutter head 21.

[0162] In this embodiment, there are three blades 22, and the three blades 22 are evenly mounted on the cutter head 21 along the circumference of the cutter head 21. One end of each blade 22, away from the center of the cutter head 21, extends beyond the cutter head 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 this application, the number of blades 22 is not limited.

[0164] In addition, the blades 22 can be distributed unevenly on the cutter head 21. As long as the cutting purpose can be achieved, the blades 22 can be arranged arbitrarily. In this embodiment, the setting position of the blades 22 is not further limited.

[0165] For example, the cutter head 21 is provided with a mounting position 23 for mounting the blade 22. The mounting position 23 can be an arc-shaped groove structure, and the blade 22 is fixed in the mounting position 23 by the fastener 24.

[0166] In the embodiment, the blade 22 can be rotatably installed on the cutterhead 21 by a screw, a rotating shaft or other installation member. That is, the blade 22 can freely rotate and also rotate with the cutterhead 21, so that the blade 22 has a certain degree of freedom, and the force between the blade 22 and the obstacle can be reduced when the blade 22 encounters small stones or other obstacles, so as to effectively protect the blade and prevent the blade from being damaged.

[0167] For example, in other embodiments, the blade 22 can also be a folding blade. When the blade 22 is not needed for mowing, the blade 22 can be folded to be located inside the cutterhead 21, that is, not exposed outside the edge of the cutterhead 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 edge of the cutterhead 21, so as to perform mowing work. Of course, in other embodiments, the blade 22 can also have other structures, which are not further described in the embodiment.

[0168] Of course, in other embodiments, the installation position 23 can also have other structures, for example, can be a hole structure, and the connecting member is a screw, and the blade 22 is fixed on the installation position 23 by the fixing member 24, so that the blade 22 is fixedly installed on the cutterhead 21. In the embodiment, the structure of the fixing member 24 and the installation position 23 is not further limited.

[0169] In a possible implementation, the cutting width of the cutting mechanism 20 is 260mm-300mm, that is, the cutting width generated by the cooperation of the blade 22 and the rotation of the cutterhead 21. Since the blade 22 generally forms a circle 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 has differences. In other embodiments, the cutting width can be greater than 300mm or less than 260mm. In the embodiment, the cutting width of the cutting mechanism 20 is not further limited.

[0170] By setting the cutting width of the cutting mechanism 20 to 260mm-300mm, the size of the cutting mechanism 20 can be expanded, and the mowing area of the mower 100 is also expanded, and the mowing efficiency is improved.

[0171] In a possible implementation, as shown in FIG. 2, the cutting mechanism 20 can include a cutterhead 21 and a blade 22. The cutterhead 21 can be rotatably installed on the mower 100, and the blade 22 can be rotatably installed on the cutterhead 21. Figure 4As shown, in the first direction, the distance between the outer side edge of the cutting mechanism 20 and the first side edge 11 of the machine body 10 is a first distance L1, and the distance between the outer side edge of the cutting mechanism 20 and the second side edge 12 of the machine body 10 is a second distance L2. In the second direction (Q direction), the distance between the outer side edge of the cutting mechanism 20 and the third side edge 13 of the machine body 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 machine body 10 can be ensured to be large, thereby ensuring that the safety performance at the third side edge 13 of the machine body 10 is high.

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

[0173] In a possible implementation, in the second direction (Q direction), the distance between the outer side edge of the cutting mechanism 20 and the fourth side edge 14 of the machine body 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 machine body 10 can be ensured to be large, thereby ensuring that the safety performance at the fourth side edge 14 of the machine body 10 is high.

[0174] It should be noted that the outer side edge of the cutting mechanism 20 refers to the outer edge at the largest dimension of the cutting mechanism 20. For example, as shown by the circular dashed line frame in Figure 4 For example, when the blade 22 is rotated to be directly opposite the third side edge 13 of the machine body 10, the third distance L3 is the distance from the end of the blade 22 away from the cutter head 21 to the third side edge 13. When the blade 22 is rotated to be directly opposite the fourth side edge 14 of the machine body 10, the fourth distance L4 is the distance from the end of the blade 22 away from the cutter head 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 structure schematic view of the protection mechanism 30 and the cutting mechanism 20 of the lawn mower 100 provided in the embodiment of the present application. Figure 6 A structure schematic view of the protection mechanism 30 and the cutting mechanism 20 of the lawn mower 100 provided in the embodiment of the present application. Figure 7 A side view of the protection mechanism 30 and the cutting mechanism 20 of the lawn mower 100 provided in the embodiment of the present application.

[0177] In combination with Figure 4 and Figure 5As shown, the first side edge 11 and the cutting mechanism 20 are provided with a protection mechanism 30, and the second side edge 12 and the cutting mechanism 20 are also provided with a protection mechanism 30.

[0178] Exemplarily, the protection mechanism 30 between the first side edge 11 and the cutting mechanism 20 is taken as a first protection mechanism 30a, and the protection mechanism 30 between the second side edge 12 and the cutting mechanism 20 is taken as a second protection mechanism 30b. The first protection mechanism 30a and the second protection mechanism 30b are oppositely 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] Hereinafter, the structures of the first protection mechanism 30a and the second protection mechanism 30b are taken as an example for description.

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

[0181] By arranging the first protection mechanism 30a to include the first protection part 32 and the second protection part 33, different positions of the first protection mechanism 30a can form a protection barrier in different directions of the lawn mower 100, so as to improve the safety of the lawn mower 100.

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

[0183] By arranging the second protection mechanism 30b to include the first protection part 32 and the second protection part 33, different positions of the second protection mechanism 30b can form a protection barrier in different directions of the lawn mower 100, so as to improve the safety of the lawn mower 100.

[0184] Continuing to refer to Figure 5 As shown, the protection mechanism 30 can further include a mounting portion 31, wherein the mounting portion 31 is used to fixedly connect the protection mechanism 30 with the machine body 10. Exemplarily, the first protection portion 32 can be connected with the mounting portion 31. The second protection portion 33 can also be connected with the mounting portion 31. Of course, in some other embodiments, the second protection portion 33 can also be connected with the first protection portion 32 (see Figure 11 As 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 through welding, riveting, clamping, one-piece forming, etc. In the embodiments of the present application, the connection mode between the mounting portion 31, the first protection portion 32 and the second protection portion 33 is not limited further.

[0186] By setting the mounting portion 31, the first protection portion 32 and the second protection portion 33 are connected with the machine body 10, and the connection stability of the first protection portion 32 and the second protection portion 33 with the machine body 10 is improved, so as to improve the service life of the mower 100.

[0187] Exemplarily, the mounting portion 31 can be a plate structure, and a mounting hole 311 for connecting with the machine body 10 is arranged on the mounting portion 31, and the machine body 10 and the mounting portion 31 can be connected through screws. Of course, in other embodiments, the machine body 10 and the mounting portion 31 can also be connected through clamping, that is, a buckle can be arranged below the machine body 10, and the mounting portion 31 is clamped in the buckle. In the embodiments of the present application, the connection mode between the machine body 10 and the mounting portion 31 is not limited further.

[0188] In a possible implementation mode, the first protection portion 32 can be in a plate shape. Exemplarily, the first protection portion 32 can be arranged at one end of the mounting portion 31 away from the center of the cutterhead 21, and one end of the first protection portion 32 is connected with the mounting portion 31, and the other end extends to the lower side of the cutterhead 21 away from the machine body 10, so that the first protection portion 32 can establish a protection barrier on the side of the cutting mechanism 20. The first protection portion 32 and the mounting portion 31 can be formed by bending a plate material by 90° or other angles. In other embodiments, the first protection portion 32 can also be in other shapes.

[0189] It should be noted that, as shown in Figure 5 The length of the first protection portion 32 in the forward direction (Q direction) of the mower 100 can be less than that of the second protection portion 33. Of course, in some other embodiments, as shown in Figure 6As shown, the length of the first protection part 32 in the advancing direction of the mower 100 can be greater than or equal to the second protection part 33, so as to expand the protection area of the first protection part 32, and further improve the safety performance of the mower 100.

[0190] By setting the first protection part 32 as a plate, 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 machine body 10. In addition, the plate 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 machine body 10, and further improve the safety of the mower 100.

[0191] As shown in Figure 7 In the vertical direction, one end of the second protection part 33 away from the machine body 10 is connected with the mounting part 31. The other end of the second protection part 33 away from the machine body 10 is located below the cutting mechanism 20. By setting the other end of the second protection part 33 away from the machine body 10 to be located below the cutting mechanism 20, the second protection part 33 can form a protection 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 mower, that is, the up-down direction in the figure. In the embodiment of the present application, below refers to the direction closer to the grass in the vertical direction in the use state of the mower.

[0193] Continuing to refer to Figure 5 and Figure 6 As shown, at least one end of the second protection part 33 in the advancing direction of the mower 100 is provided with at least one grass inlet 34.

[0194] By setting the grass inlet 34 at at least one end of the second protection part 33, when the mower 100 is used to mow grass, the grass can pass through the grass inlet 34 and contact the cutting mechanism 20, and then be cut by the cutting mechanism 20, so as to achieve the purpose of mowing.

[0195] In a possible implementation, the second protection part 33 can include at least two strip-shaped parts 331, and the at least two strip-shaped parts 331 are respectively installed in cooperation with the mounting part 31. The at least two strip-shaped parts 331 are arranged in the first direction. The gap between adjacent strip-shaped parts 331 forms the grass inlet 34.

[0196] In the embodiment, each of the strips 331 is arranged along the advancing direction of the mower 100, i.e., each of the strips 331 is parallel to the advancing direction, and all the strips 331 are arranged in parallel to each other, and the gaps between the strips 331 form the grass inlet 34. In other embodiments, the strips 331 can be arranged at an angle of 10-40° with the advancing direction of the mower 100.

[0197] By arranging the second protection part 33 as at least two strips 331, the structure of the second protection part 33 can be simplified, the machining and installation are facilitated, and the cost is reduced. In addition, the strips 331 are arranged at intervals, and the grass inlet 34 can be directly formed without arranging a specific grass inlet 34, the structure of the second protection part 33 is simplified, and the cost is reduced.

[0198] For example, the second protection part 33 can include 2, 3, 4, or 5 strips 331, and the number of the strips 331 can be set according to the size of the cutting mechanism 20. In the embodiment, the number of the strips 331 in the second protection part 33 is not limited further.

[0199] In the embodiment, the strips 331 can be cylindrical. Of course, in other embodiments, the strips 331 can be prismatic or other shapes, and the specific shape of the strips 331 is not limited further in the embodiment.

[0200] By arranging the strips 331 as cylindrical, the machining difficulty of the strips 331 is reduced, and the cost is reduced. In addition, the cylindrical structure has a smooth surface without sharp edges, and the user is not accidentally scratched, and the safety performance is high. In addition, the grass is easier to enter, and the grass is not easily stuck.

[0201] It should be noted that in the embodiment, the interval distance between the two adjacent strips 331 is not limited further in the embodiment, and in addition, the sizes of the plurality of strips 331 can be the same or different.

[0202] As shown in FIG. 4, in the direction from the outside to the inside of the cutting mechanism 20, the size of the strips 331 gradually increases, so that the plurality of strips 331 can be located on the outside of the cutting mechanism 20. In addition, a protective barrier is formed on the outside of the cutting mechanism 20. Figure 5 Of course, in other embodiments, the plurality of strips 331 can be arranged to have the same length as the largest strip 331 in the embodiment, so that the plurality of strips 331 can also be located on the outside of the cutting mechanism 20. In the embodiment, the size of the strips 331 is not limited further in the embodiment.

[0203] Figure 5 ​​

[0204] Continuing to refer to Figure 5 As shown in the second direction (Q direction), at least one end of each of the strip members 331 is provided with a bent portion, which is bent towards the mounting portion 31. Among them, at least one bent portion on each of the strip members 331 is connected with the mounting portion 31.

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

[0206] For example, as shown in Figure 5 and Figure 6 Both ends of the strip member 331 can be provided with a bent portion. The bent portion of each of the strip members 331 is connected with the mounting portion 31. Between the two bent portions 3311 is the middle portion 3312. The strip member 331, the mounting portion 31 and the first protection portion 32 form an accommodation area for accommodating the cutter head 21. In the direction from the outer side to the inner side of the cutting mechanism 20, the length of the middle portion 3312 gradually increases, so that the accommodation area also gradually increases in the direction from the outer side to the inner side of the cutting mechanism 20, so as to match the circular profile of the cutter head 21. Prevent interference between the cutting mechanism 20 and the protection mechanism 30.

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

[0208] For example, the outer end of each bent portion 3311 is detachably mounted with the mounting portion 31 or integrally formed, and the gap between the bent portions 3311 at both ends of each strip member 331 can be used for grass passing, and there is no obstacle for grass passing on both sides.

[0209] In some other embodiments, as shown in Figure 8 One end of the strip member 331 is provided with a bent portion, wherein the end provided with the bent portion can be the end of the strip member 331 towards the third side edge 13 of the machine body 10, or the end of the strip member 331 towards the fourth side edge 14 of the machine body 10.

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

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

[0212] In some other embodiments, a portion of the multiple strips 331 have a bent portion at one end facing the third side edge 13 of the body 10, and another portion of the multiple strips 331 have a bent portion at one end facing the fourth side edge 14 of the body 10. For example, the strips 331 with a bent portion at one end facing the third side edge 13 of the body 10 and the strips 331 with a bent portion at one end facing the fourth side edge 14 of the body 10 can be arranged alternately. This also increases the grass inlet 34, which reduces the obstruction of the second protective part 33 in the forward direction of the lawnmower 100, facilitates the entry of grass from the grass inlet 34 and its contact with the cutting mechanism 20, and improves the efficiency of the lawnmower 100.

[0213] It should be noted that, in the embodiments of this application, the number and location of the bends on each strip 331 are not further limited.

[0214] like Figure 9 As shown, in some embodiments, the second protective part 33 further includes a connecting part 3313. Wherein, when each strip 331 has a bent portion at one end near the third side edge 13 of the fuselage 10, the end of each strip 331 near the fourth side edge 14 of the fuselage 10 is connected to the connecting part 3313. For example, the connecting part 3313 can be a plate-like structure that connects the ends of multiple strips 331 toward the fourth side edge 14 to improve the structural stability of the second protective part 33.

[0215] By providing a bending portion 3311 on the strip 331, the strip 331 is made into an "L" shape, creating a certain distance between the middle portion 3312 of the strip 331 and the mounting portion 31. This bending portion 3311 forms an accommodating area for the cutter disc 21, enclosing 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, causing the width of the accommodating area in the forward direction of the lawnmower 100 to also gradually increase from the outside to the inside of the cutting mechanism 20, thus matching the circular outline of the cutter disc 21 and ensuring that the cutting width is not affected by the accommodating area. Simultaneously, this bending portion 3311 also establishes a protective barrier on the side of the cutter disc 21 near the front end of the machine body 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 are separately arranged in the above embodiment, and in some other embodiments, as shown in FIG. 6, the mounting portion 31 of the first protection mechanism 30a and the mounting portion 31 of the second protection mechanism 30b can be arranged as one whole, which can increase the positions of the mounting portion 31 for connecting with the machine body 10, and further improve the connection stability between the protection mechanism 30 and the machine body 10. Figure 10

[0217] Of course, in other embodiments, the protection mechanism 30 can also have other structures. For example, as shown in FIG. 7, the protection mechanism 30 can be arranged as an integrated structure, and the second protection portion 33 includes a plate structure, and the second protection portion 33 is arranged at one end of the first protection portion 32 away from the machine body 10, wherein in the first direction, the second protection portion 33 extends from the outer edge of the cutting mechanism 20 to the center of the cutting mechanism 20. Figure 11

[0218] In the present 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 have a U-shaped structure. As shown in FIG. 8, the opening of the U-shaped structure faces the center of the cutter head 21, and the area surrounded between the mounting portion 31, the second protection portion 33 and the first protection portion 32 can accommodate part of the cutter head 21. The grass inlet 34 is arranged at both ends of the second protection portion 33. Alternatively, in the second direction (Q direction), at least one grass inlet 34 is arranged at both ends of the second protection portion 33. Figure 12

[0219] By arranging the protection mechanism 30 as an integrated structure, the machining is facilitated, and the structural strength of the protection mechanism 30 is improved, and the service life of the protection mechanism 30 is further improved. In addition, by arranging the second protection portion 33 as a plate structure and connecting one end with the first protection portion 32, the obstruction of the second protection portion 33 in the second direction (Q direction) can be reduced, the grass can be conveniently fed, and the mowing efficiency is improved.

[0220] For example, a plurality of grass inlets 34 are arranged at one end of the second protection portion 33 close to the front end (the third side edge 13) of the machine body 10, and the number of the grass inlets 34 can be two or more than three according to the needs, and the grass can be fed through the grass inlets 34 for cutting.

[0221] ​​​By positioning the grass inlet 34 at one end of the second protective part 33 facing the third side edge 13, the grass can easily pass through the grass inlet 34 and come into contact with the cutting mechanism 20 during the forward movement of the lawnmower 100, thus being cut by the cutting mechanism 20 to achieve the purpose of mowing. By positioning the second protective part 33 at one end of the first protective part 32 away from the machine body 10, the first protective part 32 and the second protective part 33 can be connected without needing to connect the second protective part 33 to the mounting part 31. This simplifies the structure of the mounting part 31 and reduces costs.

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

[0223] By providing several grass inlets 34 at both ends of the second protective section 33, grass can easily pass through the grass inlets 34 and come into contact with the cutting mechanism 20 when the mower 100 moves forward or backward, and then be cut by the cutting mechanism 20 to achieve the purpose of mowing. In addition, when the mower 100 moves forward, the grass inlet 34 facing the fourth side edge 14 of the body 10 can be used as a grass discharge outlet. That is to say, 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 to prevent the cutting mechanism 20 from getting stuck.

[0224] In addition, the grass inlet 34 extends from the end of the second protective part 33 along the second direction in a direction away from the end of the second protective part 33, so that grass can enter the second protective part 33 from the grass inlet 34 during the cutting operation. This allows the grass entering from the grass inlet 34 to be closer to the cutting mechanism 20, thereby improving the cutting efficiency of the lawnmower 100.

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

[0226] Of course, in other embodiments, the protective mechanism 30 may be configured with other structures, which will not be further described in this embodiment.

[0227] This application also provides a lawnmower 100, such as Figure 13 As shown, the lawnmower 100 includes a body 10, which has a first side edge 11 and a second side edge 12 disposed opposite to each other along a first direction, the first direction intersecting the forward direction of the lawnmower 100.

[0228] For example, the first direction can be perpendicular to the advancing direction of the mower 100, or the first direction can be arranged at an angle, for example, 85°, 86°, etc., with respect to the advancing direction of the mower 100. In the embodiments of the present application, the angle between the first direction and the advancing direction of the mower 100 is not limited further.

[0229] By arranging the first direction to be perpendicular to the advancing direction of the mower 100, the safety performance of the mower 100 can be improved. For example, when the two ends in the advancing direction of the mower 100 are the front end and the rear end of the mower 100 respectively, the first direction is arranged to be perpendicular to the advancing direction of the mower 100, and then the first side edge 11 and the second side edge 12 of the machine body 10 are the left side and the right side of the mower 100, so that the protective barriers are provided on the left side and the right side of the mower 100, thereby improving the safety performance of the mower 100.

[0230] As shown in FIG. 1, the mower 100 can further include a cutting mechanism 20, wherein the cutting mechanism 20 is located below the machine body 10 and is used to perform cutting work. Figure 13

[0231] For example, the machine body 10 can be provided with an output shaft (not shown in the figure), and the output shaft is cooperatively installed with the cutting mechanism, wherein the output shaft is used to drive the cutting mechanism to rotate, so that the cutting mechanism can perform cutting work.

[0232] For example, the rotation center line of the cutting mechanism 20 coincides with the axis of the output shaft. The machine body 10 can be provided with a control device, which 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 work.

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

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

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

[0236] By setting the first distance H1 and / or the second distance H2 to less than 50mm, the distance from the cutting mechanism 20 to the outer side of the body 10 can be kept small, which is beneficial for the lawnmower 100 to get closer to the edge of the grass being cut, reduce the range of manual trimming, and thus improve the automation of the intelligent lawnmower 100.

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

[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 smaller than the second distance H2, or the first distance H1 can be set larger than the second distance H2. In this case, if the first distance H1 and / or the second distance H2 are set to be less than 50mm, the distance from the outer edge of the cutting mechanism 20 (at least located at the first side edge 11 or the second side edge 12) of the lawnmower 100 to the outer edge of the body 10 is less than 50mm, thereby achieving the technical effect that the lawnmower 100 can cut to the edge. In this embodiment, the quantitative relationship between the first distance H1 and the second distance H2 is not further limited; it can be set according to requirements.

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

[0240] It should be noted that, in this embodiment of the application, the lawnmower 100 may further include a drive wheel 40 and a driven wheel 50. The drive wheel 40 is installed at the rear end of the body 10, and the driven wheel 50 is installed at the front end of the body 10; alternatively, the drive wheel 40 may be installed at the front end of the body 10, and the driven wheel 50 at the rear end of the body 10.

[0241] like Figure 13 As shown, two drive wheels 40 are respectively installed on the inner rear end of the body 10. The drive wheels 40 are driven by a motor on the body 10, meaning that the lawnmower 100 is a rear-drive lawnmower 100. The driven wheels 50 are installed on the inner front end of the body 10, and the driven wheels 50 are preferably casters. By setting the drive wheels 40 and driven wheels 50, the lawnmower 100 can move and turn.

[0242] The driving wheel 40 and the driven wheel 50 are both provided with two, in other embodiments, the driven wheel 50 can be provided with only one, or the number of the driven wheel 50 can also be increased as needed, the number of the driving wheel 40 can also be increased or decreased as needed. In the embodiment of the application, the number of the driving wheel 40 and the driven wheel 50 is not limited further.

[0243] Exemplarily, the direction from the driving wheel 40 to the driven wheel 50 is the advancing direction of the mower 100, by arranging the driving wheel 40 on the inner side of the rear end of the machine 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 machine body 10 can be reduced, so that the mower 100 can cut to the edge of the lawn.

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

[0245] By arranging the first distance H1 and / or the second distance H2 to be less than 45mm, the distance from the cutting mechanism 20 to the outer side of the machine body 10 can be further reduced, which is more conducive to the mower 100 to be closer to the edge of the lawn to be cut, reduces the range of manual pruning, and thus improves the automation of the intelligent mower 100.

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

[0247] By arranging the first distance H1 and / or the second distance H2 to be less than 40mm, the distance from the cutting mechanism 20 to the outer side of the machine body 10 can be further reduced, which is more conducive to the mower 100 to be closer to the edge of the lawn to be cut, reduces the range of manual pruning, and thus improves the automation of the intelligent 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 can 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 application, the specific values of the first distance H1 and the second distance H2 are not limited further

[0250] In a possible implementation, the mower 100 further comprises a protection mechanism 30, the protection mechanism 30 is arranged below the body 10, and the protection mechanism 30 is arranged between the first side edge 11 and the cutting mechanism 20 and between the second side edge 12 and the cutting mechanism 20, and the protection mechanism 30 is configured to establish a protection barrier below the first side edge 11 and the second side edge 12 of the body 10.

[0251] By arranging the protection mechanism 30 between the cutting mechanism 20 and the first side edge 11 of the body 10 and between the cutting mechanism 20 and the second side edge 12 of the body 10, and arranging the protection mechanism 30 to establish a protection barrier below the first side edge 11 and the second side edge 12 of the body 10, the safety performance of the 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 in a second direction, and the second direction is the advancing direction of the mower 100. The protection mechanism 30 is not arranged 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 advancing direction of the mower, that is, the second direction. The L direction in the figure represents the direction towards the left end, the left side or the first side edge of the mower. The R direction represents the direction towards the right end, the right side or the second side edge of the mower. The A direction represents the direction towards the front end, the front side or the third side edge of the mower. The B direction represents the direction towards the rear end, the rear side or the fourth side edge of the mower. The U direction represents the upper direction, and the D direction represents the lower direction. The vertical direction and the thickness direction of the mower are the directions of the D and U directions in the figure.

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

[0255] It should be noted that, when the body 10 is a quadrilateral as shown in Figure 13 In the embodiment of the present application, the first side edge 11 and the second side edge 12 are respectively the outer side edges of the left side and the right side of the body 10. The third side edge 13 and the fourth side edge 14 are respectively the two side edges arranged opposite at the front end and the rear end of the body 10, and in the embodiment of the present application, the third side edge 13 and the fourth side edge 14 are respectively the outer side edges of the front side and the rear side of the body 10.

[0256] In other embodiments, for example, when the fuselage 10 has a circular, arc-shaped, or irregular structure, the first side edge 11 and the second side edge 12 are respectively partial side edges surrounding the front and rear ends of the fuselage 10. The third side edge 13 is a side edge surrounding the vicinity of the front end of the fuselage 10, and the fourth side edge 14 is a partial side edge surrounding the vicinity of the rear end. Additionally, 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 edges of the fuselage 10.

[0257] In one possible implementation, no protective mechanism 30 is provided between the fourth side edge 14 and the cutting mechanism 20.

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

[0259] In some embodiments, the number of protective mechanisms 30 is two, wherein the two protective mechanisms 30 are disposed opposite to each other between the first side edge 11 of the body 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 protective mechanisms 30 may also be three, wherein the three protective mechanisms 30 are respectively disposed between the first side edge 11 and the cutting mechanism 20, the second side edge 12 and the cutting mechanism 20, and the third side edge 13 and the cutting mechanism 20. Alternatively, the three protective mechanisms 30 are respectively disposed between the first side edge 11 and the cutting mechanism 20, the second side edge 12 and the cutting mechanism 20, and the fourth side edge 14 and the cutting mechanism 20.

[0261] In this embodiment, the number of protective mechanisms 30 is not further limited.

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

[0263] Figure 14 A bottom view of a lawnmower 100 removing the protective mechanism 30, provided for an embodiment of this application.

[0264] like Figure 14 As shown, the cutting mechanism 20 includes a cutter head 21 and blades 22 mounted on the cutter head 21. An output shaft is fitted to the cutter head 21 to drive the cutter head 21 to rotate. In this embodiment, the rotation center line of the cutting mechanism 20 is the rotation center line of the cutter head 21.

[0265] In the embodiment, the number of the blades 22 is three, and the three blades 22 are evenly installed on the cutter head 21 along the circumferential direction of the cutter head 21. The end of the blade 22 away from the center of the cutter head 21 extends out of the cutter head 21, so that the blade 22 can perform cutting operation.

[0266] It should be noted that the number of the blades 22 can be selected as required, for example, the number of the blades 22 can be set to 1, 2, 3, 4 or more, and the number of the blades 22 is not limited in the embodiment.

[0267] In addition, the distribution of the blades 22 on the cutter head 21 can also be uneven distribution, as long as the cutting purpose can be achieved, the blades 22 can be arranged arbitrarily, and the setting position of the blades 22 is not limited in the embodiment.

[0268] For example, the cutter head 21 is provided with a mounting position 23 for mounting the blade 22, and the mounting position 23 can be an arc-shaped groove structure. The blade 22 is fixed in the mounting position 23 by the fixing member 24.

[0269] In the embodiment, the blade 22 can be rotatably installed on the cutter head 21 by screws, shafts or other mounting members. That is, the blade 22 can rotate freely, and also rotates with the cutter head 21. In this way, the blade 22 has a certain degree of freedom, which can reduce the force between the blade 22 and the obstacle when encountering small stones or other obstacles, and can effectively protect the blade and prevent the blade from being damaged.

[0270] For example, in some other embodiments, the blade 22 can also be set as a folding blade. When the blade 22 is not needed for mowing, the blade 22 can be folded to be located inside the cutter head 21, that is, not exposed to the outer edge of the cutter head 21. When the blade 22 is needed for mowing, the blade 22 can be unfolded, and the cutting surface of the blade 22 extends out of the outer edge of the cutter head 21, so as to perform mowing operation. Of course, in other embodiments, the blade 22 can also have other structures, which are not limited in the embodiment.

[0271] Of course, in other embodiments, the mounting position 23 can also have other structures, for example, can be a hole structure, and the connecting member is a screw, and the blade 22 is fixed on the mounting position 23 by the fixing member 24, so that the blade 22 is fixedly installed on the cutter head 21. In the embodiment, the structure of the fixing member 24 and the mounting position 23 is not limited.

[0272] In one possible implementation, the cutting width of the cutting mechanism 20 is 260mm to 350mm, which is the cutting width generated by the rotation of the blade 22 in conjunction with the cutter head 21. Since the blade 22 is generally circular when rotating, the cutting width can be the diameter of the circle. For example, the diameter of the circle can be 260mm, 280mm, 300mm, 320mm, 340mm, 350mm, etc. In this embodiment, the cutting width is not further limited. 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 350mm or less than 260mm. In this embodiment, the cutting width of the cutting mechanism 20 is not further limited.

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

[0274] In one possible implementation, such as Figure 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 body 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 body 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 body 10 is a third distance H3. The third distance H3 is greater than the first distance H1 and greater than the second distance H2. This ensures that the distance between the cutting mechanism 20 and the third side edge 13 of the body 10 is relatively large, thereby ensuring higher safety performance at the third side edge 13 of the body 10.

[0275] In one 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 body 10 is a fourth distance H4. This fourth distance is greater than the first distance H1 and greater than the second distance H2. This ensures that the distance between the cutting mechanism 20 and the fourth side edge 14 of the body 10 is relatively large, thereby ensuring higher safety performance at the fourth side edge 14 of the body 10.

[0276] It should be noted that the outer edge of the cutting mechanism 20 is the outer edge at the maximum size of the cutting mechanism 20, such as... Figure 14 The circular dashed box in the diagram illustrates this. For 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 cutter head 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 cutter head 21 to the fourth side edge 14.
