The mounting block 31 is driven and connected by the driving device 4 so that the blade disc assembly 3 has a movement stroke in the horizontal direction, thereby expanding the cutting range of the blade disc assembly 3, thereby improving the weeding efficiency of the intelligent lawn mower 1000.
[0043] For further information, please refer to Figure 2 The driving device 4 includes a first driving part 41, and the first driving part 41 includes a first motor 411 and a first screw 412; the first motor 411 has a forward and reverse running path; the first screw 412 extends in the horizontal direction, and the main shaft of the first motor 411 drives the first screw 412 to be connected along the extending direction of the first screw 412; wherein, the mounting block 31 is sleeved on the first screw 412; the first motor 411 drives the mounting block 31 to move along the extending direction of the first screw 412. It can be understood that in order to realize the movement stroke of the drive device 4 driving the blade disc assembly 3 along the horizontal direction, specifically, the drive device 4 includes the first drive part 41, and the first drive part 41 includes the first motor 411 and the first screw 412; the first motor 411 has a forward and reverse operation path; the first screw 412 extends in the horizontal direction, and the main shaft of the first motor 411 drives the first screw 412 to connect along the extension direction of the first screw 412; wherein, the mounting block 31 is sleeved on the first screw 412; the first motor 411 drives the mounting block 31 to move along the extension direction of the first screw 412, thereby realizing the movement of the blade disc assembly 3 along the horizontal direction, and further obtaining a larger range of cutting diameters, thereby improving the weeding efficiency of the intelligent lawn mower 1000.
[0044] For further information, please refer to Figure 2 , the driving device 4 further includes a guide structure 42 for limiting the blade disc to have a relatively unique movement direction in the horizontal direction. It can be understood that in order to make the blade disc assembly 3 have a relatively unique movement stroke, so as to prevent the blade disc assembly 3 from cutting the wheel body 2; specifically, the driving device 4 further includes the guide structure 42 for limiting the blade disc to have a relatively unique movement direction in the horizontal direction, thereby protecting the wheel body 2 from being damaged by the blade disc assembly 3.
[0045] Furthermore, the guide structure 42 includes a guide column 421 and a guide block 422 . The guide column 421 is arranged parallel to the first screw rod 412 , and both ends are connected to the main body 1 . The guide block 422 is sleeved on the guide column 421 and fixedly connected to the first driving part 41 .

[0046] In addition, please refer to Figure 2 , the driving device 4 further includes a second driving part 43, which is disposed between the first driving part 41 and the blade assembly 3, and is used to drive the blade assembly 3 to move in the up-down direction. It can be understood that in some embodiments, the height of the grass being cut remains unchanged, which makes it impossible to clear some vegetation close to the ground, thereby making the application scenarios of the intelligent lawn mower 1000 relatively few; therefore, in another embodiment, the driving device 4 further includes the second driving part 43, which is disposed between the first driving part 41 and the blade assembly 3, and is used to drive the blade assembly 3 to move in the up-down direction, thereby making the blade assembly 3 have more application scenarios, on the one hand, it can choose how long the weeds are to be kept on the ground, and on the other hand, it can have a clearing effect on vegetation of different heights.
[0047] Furthermore, the second driving part 43 includes a second motor 431 and a second screw 432; the second motor 431 has a forward and reverse running path, and the second motor 431 is partially sleeved on the first screw 412; the second screw 432 extends in a vertical direction, and the main shaft of the second motor 431 drives the second screw 432 to be connected along the extending direction of the second screw 432; wherein, the mounting block 31 is sleeved on the second screw 432; the second motor 431 drives the mounting block 31 to move along the extending direction of the second screw 432. It can be understood that in order to make the cutter disc assembly 3 have a movement stroke in the vertical direction, specifically, the second driving part 43 includes the second motor 431 and the second screw 432; the second motor 431 has a forward and reverse operation path, and the second motor 431 is partially sleeved on the first screw 412; the second screw 432 extends in the vertical direction, and the main shaft of the second motor 431 drives the second screw 432 to be connected along the extension direction of the second screw 432; wherein, the mounting block 31 is sleeved on the second screw 432; the second motor 431 drives the mounting block 31 to move along the extension direction of the second screw 432; and thus the cutter disc assembly 3 has a movement stroke in the vertical direction as driven by the second motor 431, and thus has more application scenarios and better adaptability.
[0048] In addition, please refer to Figure 2 , the blade assembly 3, the first driving unit 41 and the second driving unit 43 are set as a mowing group, and two mowing groups are provided, which are spaced and symmetrically arranged on both sides of the forward direction of the main body 1. It can be understood that the horizontal movement stroke of the blade assembly 3 moves along the width direction of the main body 1, that is, when the main body 1 moves forward, the blade assembly 3 needs to take into account the weeds on the left and right sides of the movement direction. Therefore, in order to better improve the weeding efficiency of the intelligent lawn mower 1000, the blade assembly 3, the first driving unit 41 and the second driving unit 43 are set as a mowing group, and two mowing groups are provided, which are spaced and symmetrically arranged on both sides of the forward direction of the main body 1. Therefore, each blade assembly 3 only needs to take into account the weeds on its own side, thereby further accelerating the weeding efficiency of the intelligent lawn mower 1000.
[0049] In addition, please refer to Figure 2 and Figure 3, the blade disc assembly 3 includes a third motor 32 and a blade disc member 33; the third motor 32 is fixedly arranged on one side of the mounting block 31; the blade disc member 33 extends in the horizontal plane direction, and the main shaft of the third motor 32 is driven and connected to the blade disc member 33 in the up-down direction. It can be understood that the blade disc assembly 3 is a device for directly weeding. In order to achieve the effect of quickly cutting weeds, specifically, the blade disc assembly 3 includes the third motor 32 and the blade disc member 33; the third motor 32 is fixedly arranged on one side of the mounting block 31; the blade disc member 33 extends in the horizontal plane direction, and the main shaft of the third motor 32 is driven and connected to the blade disc member 33 in the up-down direction, thereby, the third motor 32 drives the blade disc member 33 to rotate at a high speed, thereby quickly cutting the weeds.
[0050] For further information, please refer to Figures 1 to 3 The blade assembly 3 further includes a protective cover 34, which is disposed between the third motor 32 and the blade member 33. It is understandable that during the cutting process of the blade member 33, weeds and stones are splashed everywhere, and are very likely to splash into the drive device 4, thereby damaging the intelligent lawn mower 1000. Therefore, in order to protect the drive device 4 from being invaded by weeds and stones, the blade assembly 3 further includes the protective cover 34, which is disposed between the third motor 32 and the blade member 33, and the blade member 33 is covered by the protective cover 34, thereby protecting the drive device 4.
[0051] In addition, please refer to Figure 1 , and also includes a binocular camera 5, which is arranged in the direction of movement of the main body 1 to obtain road condition information. It can be understood that the intelligent lawn mower 1000 has the functions of automatic obstacle avoidance and positioning, and it is necessary to obtain the field of view. Therefore, the intelligent lawn mower 1000 also includes the binocular camera 5, which is installed on the main body 1 to obtain the road conditions on the route. The binocular camera 5 is a machine vision device based on the parallax principle. It obtains two images of the measured object from different positions through two cameras. There is a position deviation between the two images. By calculating these deviations, the binocular camera 5 can obtain the three-dimensional geometric information of the object. Therefore, the intelligent lawn mower 1000 can obtain the field of view information relatively accurately through the binocular camera 5, and then can automatically avoid obstacles or self-position the route of travel, etc. In order to better enable the intelligent lawn mower 1000 to move forward and backward freely, the binocular camera 5 is provided with two, which are respectively installed on the front and rear sides of the main body 1, so as to obtain the field of view in more directions.
[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
