For example, the projections of the trimming area of the trimming device 200 and the cutting area of the cutting device 300 in the height direction of the fuselage 100 have an overlapping part; or, the projections of the trimming area of the trimming device 200 and the cutting area of the cutting device 300 in the height direction of the fuselage 100 are arranged at intervals, but the projections of the trimming area of the trimming device 200 and the cutting area of the cutting device 300 in the transverse direction of the fuselage have an overlapping part; or other setting ways.

Through the cooperation of the trimming device 200 including the flexible trimming element 210 and the cutting device 300 including the rigid cutting element, the grass and other plants within the preset range and in the area along the edge of the preset range can be trimmed better.

[0087] This embodiment provides an operation method using the above-mentioned lawn mower, which includes the following steps:

[0088] Start the edging function, the lawn mower walks along the first direction along the preset boundary line, and the edging device 200 works and / or the cutting device 300 works; optionally, the preset boundary line can be circular, linear, curved, irregular or other shapes.

[0089] After that, the lawn mower walks along the second direction along the preset boundary line, and the cutting device 300 works and / or the edging device 200 works; wherein, the second direction is the opposite direction of the first direction, that is, the lawn mower walks along the opposite direction of the preset boundary line.

[0090] That is to say, after starting the edging function in this embodiment, the lawn mower can walk along the first direction along the preset boundary line, the edging device 200 works to trim plants, and the cutting device 300 stops working; after that, the lawn mower walks along the second direction along the preset boundary line, the cutting device 300 works to trim and cut plants, and the edging device 200 stops working;

[0091] It can also be that after starting the edging function, the lawn mower can walk along the first direction along the preset boundary line, the cutting device 300 works to trim and cut plants, and the edging device 200 stops working; after that, the lawn mower walks along the second direction along the preset boundary line, the edging device 200 works to trim plants, and the cutting device 300 stops working;

[0092] It can also be that after starting the edging function, the lawn mower can walk along the first direction along the preset boundary line, and both the edging device 200 and the cutting device 300 work to trim and cut plants; after that, the lawn mower walks along the second direction along the preset boundary line, and both the edging device 200 and the cutting device 300 work to trim and cut plants.

[0093] Optionally, when the lawn mower walks along the first direction along the preset boundary line, it can walk all or part of the preset boundary line, or can walk along the preset boundary line once or multiple times; for example, when the preset boundary line is circular, the lawn mower walks along the first direction for a full circle, multiple circles or a half circle.

[0094] Optionally, when the lawn mower walks along the second direction along the preset boundary line, it can walk all or part of the preset boundary line, or can walk along the preset boundary line once or multiple times; for example, when the preset boundary line is circular, the lawn mower walks along the second direction for a full circle, multiple circles or a half circle.

[0095] See Figures 15-18 As shown, in the optional solution of this embodiment, start the edging function, the lawn mower walks along the first direction along the preset boundary line, the cutting device 300 works, and the edging device 200 stops working; as Figure 15 and Figure 16, when the cutting device 300 is working, the cutting device 300 fails to completely trim to the edge.

[0096] After that, the lawn mower walks along the preset boundary line in the second direction. The edging device 200 works to trim the plants outside the preset boundary line, and the cutting device 300 stops working; as Figure 17 and Figure 18 , when the edging device 200 is working, the edging device 200 can completely trim to the edge.

[0097] By first making the cutting device 300 including rigid cutting elements perform the trimming work, and then making the edging device 200 with the flexible trimming element 210 perform the trimming work, the actual cutting width of the flexible trimming element 210 is reduced, so that the edge cutting effect is better, and the wear of the flexible trimming element 210 is also reduced, making the flexible trimming element 210 more durable.

See Figure 12 As shown, the edging device 200 is arranged as much as possible on the front side of the fuselage 100, that is, near the head; see Figure 13 As shown, the edging device 200 is arranged as much as possible in the middle of the fuselage 100, that is, near the middle; see Figure 14 As shown, the edging device 200 is arranged as much as possible on the rear side of the fuselage 100, that is, near the tail.

[0099] See Figures 12-14 As shown, when the edging device 200 is arranged at different positions on the fuselage 100, the uncut area at the corner is different; among them, the uncut area of the edging device 200 near the head is smaller than that of the edging device 200 near the middle; the uncut area of the edging device 200 near the middle is smaller than that of the edging device 200 near the tail. Therefore, the edging device 200 is arranged as much as possible on the front side of the fuselage 100, that is, near the head, and the uncut area at the corner is smaller when turning.

[0100] Combined with Figure 15 and Figure 17 As shown, this embodiment also provides a mowing system, including a power supply station 400 and the above-mentioned lawn mower;

[0101] The power supply station 400 is used to supply electric energy to the lawn mower. The power supply station 400 can supply power to the lawn mower in a wired or wireless manner.

[0102] The mowing system includes the mower described above; the technical features of the mower also apply to the mowing system, and the publicly disclosed technical features of the mower will not be described repeatedly. The mowing system has the advantages of the mower, and the publicly disclosed advantages of the mower will not be described repeatedly here.
