Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

An intelligent lawn mower 100 according to an embodiment of the present application is described below with reference to fig. 1-2.

The intelligent lawn mower 100 according to the embodiment of the present application includes: chassis 10, drive module, control module and cutting module 20.

Wherein the cutting module 20 is linked with the chassis 10, the cutting module 20 is rotatable relative to the chassis 10, and the control module controls the cutting module 20 to reciprocate relative to the chassis 10.

It should be noted that the driving module may be configured to drive the cutting module 20 to rotate relative to the chassis 10, so that the cutting module 20 may perform a cutting action to cut grass through the cutting module 20, and the driving module may also drive the intelligent lawn mower 100 to move through the driving module, so as to cut grass along with the movement of the intelligent lawn mower 100.

Further, the control module can control the cutting module 20 to move back and forth relative to the chassis 10, so that the cutting module 20 can perform a mowing action on the covered area along the moving path of the cutting module during the back and forth movement. This increases the mowing area of the intelligent mower 100, and improves mowing efficiency of the intelligent mower 100.

When the intelligent mower 100 moves relative to the ground and the cutting module 20 moves back and forth relative to the chassis 10, the area covered by the cutting module 20 can be reasonably increased. Under the condition that the moving path of the intelligent mower 100 is constant, the cutting module 20 can move back and forth, and the area of the area covered by the cutting module 20 along with the movement of the intelligent mower 100 is large, so that the mowing efficiency of the intelligent mower 100 can be improved.

It should be noted that, in order to ensure that the cutting module 20 can improve the mowing efficiency of the intelligent mower 100, the moving direction of the cutting module 20 relative to the chassis 10 is not collinear or parallel with the traveling direction of the intelligent mower 100, i.e. there is a certain angle therebetween.

According to the intelligent lawn mower 100 of the embodiment of the application, by configuring the cutting module 20 to be rotatable and movable relative to the chassis 10, the cutting module 20 which rotates relative to the chassis 10 and reciprocates can increase the mowing range of the intelligent lawn mower 100 when the intelligent lawn mower 100 is operated, so that the mowing efficiency of the intelligent lawn mower 100 can be improved.

In some embodiments of the present application, the chassis 10 has a first position 11 and a second position 12, and the control module controls the cutting module 20 to move back and forth between the first position 11 and the second position 12.

It is understood that "traverse" refers to: the cutting module 20 moves from the first position 11 to the second position 12, and then moves from the second position 12 to the first position 11. However, the initial position of the cutting block 20 is not limited to the first position 11 or the second position 12, and the initial position of the cutting block 20 may be any position between the first position 11 and the second position 12, i.e., any position on the reciprocating path.

Further, when the intelligent mower 100 is operated, as the intelligent mower 100 travels, the cutting module 20 also moves back and forth between the first position 11 and the second position 12 relative to the chassis 10, and the movement path of the cutting module 20 relative to the chassis 10 intersects the travel direction of the cutting intelligent mower 100. Therefore, the mowing range of the intelligent mower 100 can be increased, and the mowing efficiency of the intelligent mower 100 can be improved.

In some embodiments of the present application, the moving speed of the chassis 10 is V, the time for the cutting module 20 to complete a round trip between the first position 11 and the second position 12 is t, and the diameter of the cutting module 20 is D, where Vt ≦ D.

It should be understood that, when the cutting module 20 moves from the first position 11 to the second position 12 and moves to the first position 11 again, it is a movement cycle, and the movement process of the cutting module 20 moving to the second position 12 after moving to the first position 11 at any one of the first position 11 and the second position 12 and returning to the initial position is a movement cycle. t refers to the time of one movement cycle of the cutting module 20. Vt is a displacement of the chassis 10 movement when the cutting module 20 moves for one movement cycle, which is required to be equal to or less than the diameter D of the cutting module 20, thereby preventing undesirable mowing effect of the cutting module 20 due to the chassis 10 traveling too fast.

It should be noted that the "poor mowing effect" of the cutting module 20 means that there is a large amount of uncut grass on the route traveled by the intelligent lawn mower 100. When the relation Vt is less than or equal to D, the cutting module 20 may be in sufficient contact with the grass of the intelligent lawn mower 100, thereby ensuring the mowing effect of the intelligent lawn mower 100.

In some embodiments of the present application, the lateral distance between the first position 11 and the second position 12 is greater than the width of the chassis 10. When the cutting module 20 reciprocates between the first position 11 and the second position 12, the width of the area covered by the cutting module 20 is greater than the width of the chassis 10, so that the area of the intelligent lawn mower 100 approach can be sufficiently cleaned by the cutting module 20 during the travel of the intelligent lawn mower 100.

Therefore, on the premise that the cutting module 20 has a large cutting width (i.e. the transverse distance between the first position 11 and the second position 12), the size of the cutting module 20 is reasonably reduced, so that the design requirement that the small-size cutting module 20 has a large cutting width is met. Meanwhile, the cutting module 20 occupies a small space in the intelligent lawn mower 100, so that the size of the intelligent lawn mower 100 can be adjusted conveniently, and the intelligent lawn mower 100 can pass through a narrow passage.

Further, if the intelligent lawn mower 100 is located in a narrow passageway, the control module controls the cutting module 20 to stop moving or reduce the moving range, so that the cutting module 20 can be prevented from contacting with the passageway wall or peripheral foreign objects, and the safety and reliability of the intelligent lawn mower 100 during operation can be improved.

In some embodiments of the present application, the smart lawn mower 100 includes an obstacle detection module for detecting an obstacle in the width direction. It can be understood that the cutting module 20 moves back and forth in the width direction of the intelligent lawn mower 100, so that an obstacle in the path of the cutting module 20 needs to be detected to effectively prevent the cutting module 20 from contacting the obstacle, so as to protect the cutting module 20 and improve the safety of the intelligent lawn mower 100 during operation.

Further, if the obstacle detection module detects that the cutting module 20 is in contact with an obstacle, the control module controls the cutting module 20 to stop moving or reduce the moving range, so that the working mode of the cutting module 20 can be timely adjusted, the problem that the cutting module 20 is damaged due to contact with the obstacle is solved, and the safety of the intelligent mower 100 during working is improved.

It should be noted that the area corresponding to the detection action of the obstacle detection module corresponds to the area where the cutting module 20 does not reach, and whether the cutting module 20 will contact the obstacle is determined according to the operation mode of the cutting module 20, and if the contact occurs, the control module controls the cutting module 20 to execute the action.

Further, if the distance of the obstacle detected by the obstacle detection module is smaller than the preset distance, the control module controls the cutting module 20 to stop moving or reduce the moving range. Therefore, the working mode of the cutting module 20 can be timely adjusted, the problem that the cutting module 20 is damaged due to contact with obstacles is solved, and the safety of the intelligent mower 100 during working is improved.

Specifically, the cutting module 20 is in high-speed operation and performs reciprocating motion in the width direction during the operation process, so that a certain distance is reserved between the cutting module 20 and an obstacle, and the safety of the cutting module 20 during operation can be effectively improved.

Specifically, the obstacle detection module includes: and the sensors can collect the position information of objects around the intelligent mower 100 relative to the intelligent mower 100 and feed the position information back to the control module. Accordingly, the control module may adjust the operation of the cutting module 20. Such as: to prevent the cutting module 20 from contacting the wall of the passageway when the intelligent mower 100 is located in a narrow passageway, the range of movement of the cutting module 20 between the first position 11 and the second position 12 may be reasonably reduced, and the cutting module 20 may be stopped as needed so that the cutting module 20 no longer moves relative to the chassis 10. Therefore, the safety of the intelligent mower 100 during operation can be improved, and the cutting module 20 can be well protected.

Alternatively, the intelligent lawn mower 100 may judge the environment and the terrain around it by the loaded map information. Of course, the detection mode of the intelligent lawn mower 100 is not limited to this, and the ambient environment may be detected in various ways.

In some embodiments of the present application, there is a sliding track 13 between the first position 11 and the second position 12, the cutting module 20 is adapted to the sliding track 13, and the cutting module 20 moves along the sliding track 13. The slide rail 13 has a good guiding effect on the movement of the cutting module 20, and the stability of the cutting module 20 in moving relative to the chassis 10 can be improved by the slide rail 13, so that the reliability of the intelligent mower 100 in working is improved.

Further, the slide rail 13 extends in a straight direction or a circular arc line, so that the cutting module 20 can move in the straight direction or the circular arc line direction with respect to the chassis 10. An included angle is formed between the straight line where the sliding rail 13 is located and the advancing direction of the intelligent mower 100, or the arc line where the sliding rail 13 is located intersects with the advancing direction of the intelligent mower 100.

It can be understood that the slide rail 13 extends along the width direction of the chassis 10, so that when the cutting module 20 moves along the slide rail 13, the mowing width of the intelligent mower 100 can be increased, and thus the mowing efficiency of the intelligent mower 100 can be improved.

In other embodiments of the present application, the chassis 10 has a sliding groove, the cutting module 20 is movable along the sliding groove, the sliding groove has a good guiding effect on the movement of the cutting module 20, and the stability of the cutting module 20 moving relative to the chassis 10 can be improved by the sliding groove, so as to improve the reliability of the intelligent lawn mower 100 in operation.

Further, the sliding groove extends in a linear direction or a circular arc direction, so that the cutting module 20 can move in the linear direction or the circular arc direction relative to the chassis 10. Wherein, the straight line where the sliding chute is located has an included angle with the advancing direction of the intelligent mower 100, or the circular arc line where the sliding chute is located intersects with the advancing direction of the intelligent mower 100. Therefore, the cutting width of the intelligent mower 100 for mowing can be increased, and the mowing efficiency of the intelligent mower 100 is improved.

As shown in fig. 1, the sliding groove extends along an arc line, the intelligent lawn mower 100 further includes a swing link 30, one end of the swing link 30 is connected to the chassis 10, the swing link 30 is arranged around one end of the swing link connected to the chassis 10 in a swinging manner, and the other end of the swing link 30 is connected to the cutting module 20. When the swing link 30 swings relative to the chassis 10, the cutting module 20 connected to the swing link 30 may move relative to the chassis 10 as the swing link 30 swings.

Further, the cutting module 20 may rotate around an end thereof connected to the swing link 30, so that the cutting module 20 may perform a mowing action, and the cutting module 20 may rotate while the cutting module 20 swings along with the swing link 30, that is, the cutting module 20 may perform a mowing action while swinging.

In a further embodiment of the present application, the driving module further includes a driving motor, and the driving motor is connected to the swing link 30 to drive the swing link 30 to swing. The driving motor drives the swing rod 30 to have high reliability in the movement process, so that the stability of the cutting module 20 moving along with the swing rod 30 can be ensured.

In some embodiments of the present application, the smart lawn mower 100 further comprises a guard 40, the guard 40 being used to protect the cutting module 20, the guard 40 being relatively stationary with respect to the cutting module 20, whereby the guard 40 can be moved relative to the chassis 10 in synchronization with the cutting module 20, preventing the cutting module 20 from being damaged by contact with hard objects on the ground.

Alternatively, the two shields 40 are arranged at intervals along the width direction of the chassis 10 at both sides of the first position 11 and the second position 12, and the shields 40 can provide good protection for the cutting module 20.

It will be appreciated that when the width between the first position 11 and the second position 12 is greater than the width of the chassis 10, the cutting module 20 will extend out of the chassis 10, the shroud 40 may protect the cutting module 20,

as shown in fig. 1, the cutting module 20 includes a cutter disc 21 for mounting the blades, and the cutter disc 21 is rotatable relative to the chassis 10, so that the cutter disc 21 can drive the blades to rotate relative to the chassis 10, thereby realizing the cutting action of the cutting module 20.

According to the intelligent mower 100 of the embodiment of the application, the cutting module 20 can move back and forth between the first position 11 and the second position 12 relative to the chassis 10, so that the cutting requirements of the small-size cutting module 20 and the large cutting width are met, the cutting coverage area of the intelligent mower 100 is large, grass on the ground can be sufficiently cut, and the working efficiency of the intelligent mower 100 is improved.
