[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of this specification, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in an appropriate manner.

[0035] The terms used in this utility model are for the purpose of describing specific embodiments only and are not intended to limit the utility model. For example, the terms "upper," "lower," "front," and "rear" used below to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are used only to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be understood as limiting the utility model.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] See also Figures 1 to 4 The figure shows an intelligent lawn mower 100 according to one embodiment of the present invention, which moves and works within a working area. The intelligent lawn mower 100 includes a body 1, a walking module 2 for supporting the movement of the body 1, a cutting module 3 arranged at the bottom of the body 1, a control module 4 arranged in the body 1 for controlling the automatic operation of the walking module 2 and the automatic operation of the cutting module 3, and an energy module 5 for supplying energy to the intelligent lawn mower 100.

[0038] The body 1 includes a base 11 and a top cover 12 connected to the base 11. The base 11 is used to mount functional modules such as the travel module 2, cutting module 3, control module 4, and energy module 5. The top cover 12 is configured to at least partially cover the base 11 and is sealed therewith to form a sealed cavity. The control module 4 is at least partially housed within this sealed cavity. In one embodiment of the present invention, the body 1 also includes a decorative cover 13 connected to the base 11 or the top cover 12. This decorative cover 13 primarily serves to enhance the aesthetics and recognition of the smart lawn mower 100.

[0039] The travel module 2 is used to drive the intelligent lawn mower 100 within the working area and includes a drive wheel 21 and auxiliary wheels 22 mounted on the body 1. Specifically, there are two drive wheels 21, each connected to a corresponding travel motor (not shown). The travel motor drives the drive wheels 21 to rotate, enabling the intelligent lawn mower 100 to move automatically. The auxiliary wheels 22, one or two in number, primarily serve as auxiliary support. They are located at the front of the intelligent lawn mower 100 and are not connected to the travel motor. However, they are driven to roll when supporting the intelligent lawn mower 100. Through this structural arrangement, the intelligent lawn mower 100 can be controlled by the control module 4 and flexibly move and turn on the work surface. During normal travel, the two travel motors output the same speed, directly driving or indirectly driving the intelligent lawn mower 100 to move through a gear or belt transmission structure, and the auxiliary wheel 22 also rolls along; when turning, the two travel motors output different speeds, and the intelligent lawn mower 100 will turn toward the side of the drive wheel 21 with a lower speed, or the side of the drive wheel 21 corresponding to the reverse direction.

[0040] The cutting module 3 includes at least a cutting element 31 for cutting grass and a cutting motor 32 for driving the cutting element 31. Specifically, the cutting motor 32 is mounted on the base 11 of the machine body 1 and is electrically connected to the control module, which can control the start and stop of the cutting motor 32 and adjust the speed of the cutting motor 32. The cutting motor 32 is housed in a motor barrel 33. A four-bar linkage (not shown) is provided between the motor barrel 33 and the base 11. The four-bar linkage rotatably connects the motor barrel 33 and the base 11. As a result, when the intelligent lawn mower 100 encounters obstacles such as rocks and low shrubs during operation, the cutting element 31 does not collide with the obstacles. Instead, it is pushed by the obstacles and drives the motor barrel 33 to move in the vertical direction. This not only prevents the cutting element 31 from being damaged by a hard collision with the obstacles, but also improves the intelligent lawn mower 100's obstacle-crossing capability. It should be noted that the cutting member 31 can be a cutting disc and a plurality of cutting blades mounted on the cutting disc, or can be a single cutting blade, which is not limited here.

[0041] The control module 4 is used to control the automatic movement and operation of the smart lawn mower 100. The functions it performs include controlling the cutting module 3 to start or stop working, generating a walking path and controlling the walking module 2 to walk accordingly, receiving environmental signals detected by the smart lawn mower 100, judging the power level of the energy module 5 and promptly controlling the smart lawn mower 100 to return to the docking station for automatic docking and charging, etc.

[0042] For ease of understanding, in the present invention, the horizontal working surface that the smart lawn mower 100 passes through when performing a cutting operation is used as a reference object, the plane parallel to the horizontal working surface is used as a horizontal plane, the direction perpendicular to the horizontal working surface is used as the height direction of the smart lawn mower 100, the forward and backward directions of the smart lawn mower 100 are used as the front-back direction of the smart lawn mower 100, and the left-right direction of the smart lawn mower 100 is perpendicular to the front-back direction of the smart lawn mower 100.

[0043] The smart lawn mower 100 also includes an operating button 6 movably mounted on the body 1. When the smart lawn mower 100 is in the off state, the user can long press this button to start the smart lawn mower 100. If an emergency occurs during the operation of the smart lawn mower 100, the user can stop the operation of the smart lawn mower 100 by pressing this button, thereby preventing the occurrence of dangerous accidents.

[0044] Specifically, the smart lawn mower 100 includes a magnetic assembly 7 mounted on and moving with an operating button 6, a Hall effect sensor 8 mounted within the body 1 and electrically connected to the control module 4, and a reed switch 9. When the smart lawn mower 100 is off, the user can press the operating button 6 to a preset position. The magnetic assembly 7 triggers the reed switch 9, which then switches on and emits a control signal. The control module 4 then powers the smart lawn mower 100 on based on this control signal. If an emergency occurs while the smart lawn mower 100 is operating normally, the user can quickly press the operating button 6. The control module 4 then controls the smart lawn mower 100 to stop based on the magnetic field changes detected by the Hall effect sensor 8. This allows the smart lawn mower's human-machine interface to function both as a starter and as an emergency stop, simplifying the interface, reducing cost, and enhancing aesthetics. Furthermore, the single-button operation reduces the likelihood of user error and enhances safety.

[0045] It should be noted that, in one embodiment of the present invention, when the smart lawn mower 100 is in normal working condition, if the user continues to press the operation button 6 for a long time, the reed switch 9 is continuously turned on until the preset time due to the triggering of the magnetic component 7, and at this time the control module 4 controls the smart lawn mower 100 to shut down.

[0046] The magnetic assembly 7 includes a first magnetic member 71 and a second magnetic member 72 spaced apart from the first magnetic member 71 . The detection plane of the Hall sensor 8 is located below the horizontal plane where the center line of the first magnetic member 71 is located. The reed switch 9 is located below the second magnetic member 72 . Specifically, when the smart lawn mower 100 is in the off state, the user can press the operation button 6, and the operation button 6 drives the second magnetic part 72 to move downward in the height direction of the smart lawn mower 100 and gradually approach the reed switch 9. When the operation button 6 moves to the preset position, the reed switch 9 is turned on due to the magnetic adsorption of the second magnetic part 72 and sends a control signal to the control module 4, and the control module 4 thereby controls the smart lawn mower 100 to turn on; if an emergency occurs during the operation of the smart lawn mower 100, after the user presses the operation button 6, the operation button 6 drives the first magnetic part 71 to move downward in the height direction of the smart lawn mower 100, and the horizontal plane where the center line of the first magnetic part 71 is located moves downward through the detection plane of the Hall sensor 8, so that the Hall sensor 8 can detect the magnetic field change and thereby send a signal to the control module to control the smart lawn mower 100 to stop working.

[0047] In one embodiment of the present invention, the above-mentioned control of the smart lawn mower 100 to stop working can specifically be to control the cutting module 3 and the walking module 2 to stop working, while the control module continues to maintain power supply so that the smart lawn mower can quickly resume normal operation after the emergency situation is resolved. Of course, in other embodiments, the smart lawn mower 100 can also be controlled to completely lose power, requiring the user to restart.

[0048] It should be noted that the above-mentioned magnetic component 7 including the first magnetic part 71 and the second magnetic part 72 spaced apart from the first magnetic part 71 is only an optional embodiment of the present invention. In other embodiments, only a larger magnetic part can be used to realize the start and emergency stop of the smart lawn mower with a single operation button.

[0049] The distance between the center of the first magnetic member 71 and the center of the second magnetic member 72 is no less than 12 mm. Specifically, in the horizontal direction of the smart lawn mower 100, the reed switch 9 is spaced apart from the Hall sensor 8. Correspondingly, in the height direction of the smart lawn mower 100, the second magnetic member 72 is located above the first magnetic member 71, and the distance between the first and second magnetic members 71 and 72 is no less than 5 mm. In the horizontal direction of the smart lawn mower 100, the distance between the first and second magnetic members 71 and 72 is no less than 10 mm. The first magnetic member 71 is located at the center of the operating button 6, and the second magnetic member 72 is located to one side of the first magnetic member 71. This ensures that the first and second magnetic members 71 and 72 are separated by a certain distance, so that the first magnetic member 71 does not interfere with or weaken the magnetic field of the second magnetic member 72. As a result, when the smart lawn mower 100 is off and the user presses the operating button 6 to turn it on, the second magnetic member 72 can normally activate the reed switch 9.

[0050] It should be noted that, in one embodiment of the present invention, the first magnetic member 71 and the second magnetic member 72 are constructed as cylindrical bodies, and the volume of the second magnetic member 72 is larger than the volume of the first magnetic member 71, thereby further enhancing the magnetic field strength of the second magnetic member 72, thereby further reducing the influence of the magnetic field of the first magnetic member 71 on the magnetic field strength of the second magnetic member 72.

[0051] Furthermore, the upper cover 12 includes a cylindrical receiving groove (not shown), the specific shape of which matches the shape of the operating button 6. The operating button 6 is mounted in the receiving groove and can move in the vertical direction along the groove wall of the receiving groove. The Hall sensor 8 is disposed in a receiving cavity formed by the connection between the upper cover 12 and the base 11. Specifically, in this embodiment, the control module 4 includes a circuit board for mounting the Hall sensor 8 and the reed switch 9, which is fixed to the lower surface of the upper cover 12. The receiving groove is not connected to the base 11 and is completely separated. The Hall sensor 8 and the circuit board and other electronic components are disposed in the base 11, while the receiving groove is completely free of electronic components. As a result, the function of the operating button 6 does not require consideration of waterproofing. Water will not flow from the receiving groove into the interior of the base 11, thereby improving the waterproofing effect of the intelligent lawn mower 100.

[0052] The magnetic assembly 7 also includes a third magnetic member 73 mounted on the operating button 6. In the height direction of the smart lawn mower 100, the third magnetic member 73 is located below the first magnetic member 71, and the detection plane of the Hall sensor 8 is located above the horizontal plane where the center line of the third magnetic member 73 is located. Specifically, during the operation of the smart lawn mower, if the operating button 6 accidentally falls off due to special operating conditions such as a steep slope, collision, fall, or user error, the operating button 6 will move upward in the height direction of the smart lawn mower 100 and separate from the upper cover 12. At this time, the operating button 6 will drive the third magnetic member 73 to move upward synchronously, and the horizontal plane where the center line of the third magnetic member 73 is located will move upward and pass through the detection plane of the Hall sensor 8. In this way, the Hall sensor 8 can detect the change in the magnetic field and send a signal to the control module to control the smart lawn mower 100 to stop working. Therefore, the smart lawn mower 100 will not continue to operate normally when the operating button 6 falls off, which improves safety.

[0053] Furthermore, the polarities of the ends of the first and third magnetic members 71 and 73 proximate to the Hall sensor 8 are opposite. Specifically, one of the first and third magnetic members 71 and 73 has an S pole proximate to the Hall sensor 8 and an N pole distal to the Hall sensor 8, while the other has an N pole proximate to the Hall sensor 8 and an S pole distal to the Hall sensor 8. The first and third magnetic members 71 and 73 are arranged side by side in the height direction of the intelligent lawn mower 100, and the detection plane of the Hall sensor 8 is located between the horizontal plane of the centerline of the first and third magnetic members 71 and 73 in the height direction of the intelligent lawn mower 100. This allows, on the one hand, the first and third magnetic members 71 and 73 to be more stably mounted on the operating button 6 based on the principle that opposite poles attract. On the other hand, the magnetic flux distributions of the first and third magnetic members 71 and 73 do not interfere with each other. Therefore, regardless of whether the operating button 6 moves upward or downward in the height direction, the Hall sensor 8 can accurately detect the magnetic field change and control the intelligent lawn mower 100 to stop operating, thereby enhancing safety.

[0054] In summary, in one embodiment of the present invention, by separating the second magnetic member 72 from the first magnetic member 71 and the third magnetic member 73, the interference and weakening of the magnetic field of the first magnetic member 71 and the third magnetic member 73 on the second magnetic member 72 is further avoided, so that when the smart lawn mower 100 is in the off state and the user presses the operation button 6 to turn on the power, the second magnetic member 72 can normally activate the reed switch 9.

[0055] The operating button 6 also includes at least two first holes (not shown) arranged side by side in the height direction of the smart lawn mower 100, and the first magnetic member 71 and the third magnetic member 73 are respectively installed in the first holes. In one embodiment of the present invention, the first magnetic member 71 and the third magnetic member 73 can be connected to their corresponding first holes by interference fit or other fixed connection methods.

[0056] However, in another embodiment of the present invention, the smart lawn mower 100 further includes a metal sheet (not shown) mounted on the operating button 6, and the first magnetic member 71 and the third magnetic member 73 are respectively connected to the metal sheet. Specifically, the metal sheet further includes a second hole portion corresponding to the first hole portion. After the first magnetic member 71 and the third magnetic member 73 are inserted into their corresponding first hole portions, they are connected to their respective corresponding second hole portions. In this way, the first magnetic member 71 and the third magnetic member 73 do not need to be completely fixedly connected to the corresponding first hole portion. By further magnetically connecting with the metal sheet, it can be achieved that, on the one hand, the first magnetic member 71 and the third magnetic member 73 are firmly mounted on the operating button 6. On the other hand, if there is a need for replacement, the user can still remove the first magnetic member 71 and the third magnetic member 73 from the operating button 6 and replace them by applying external force.

[0057] The operating button 6 also includes a slot (not shown) extending in the height direction of the intelligent lawn mower 100. The slot is arranged at the rear of the first hole portion, and the metal sheet is installed in the slot to achieve the limitation of the metal sheet in the front and rear directions. When the first magnetic member 71 and the third magnetic member 73 are connected to the metal sheet, due to the magnetic adsorption effect of the first magnetic member 71 and the third magnetic member 73, the first magnetic member 71 and the third magnetic member 73 installed in the first hole portion can achieve the limitation in the height direction of the metal sheet, and the metal sheet can also achieve the limitation of the first magnetic member 71 and the third magnetic member 73 in the front and rear directions. The cooperation between the first magnetic member 71 and the third magnetic member 73 and the metal sheet can make the operating button 6 structure more stable, and there is no need to consider the fixation of the metal sheet, which further simplifies the structure of the operating button 6.

[0058] It should be noted that, since the magnets used for the first magnetic part 71 and the third magnetic part 73 come in many sizes and types, and have different magnetic field strengths, in other embodiments, the detection plane of the Hall sensor 8 can also be above the horizontal plane where the center line of the first magnetic part 71 is located in the height direction of the smart lawn mower 100, and pressing or pulling out the operation button 6 can trigger the emergency braking of the smart lawn mower 100, ensuring that the detection plane of the Hall sensor 8 is above the horizontal plane where the center line of the third magnetic part 73 is located.

[0059] The present invention is not limited to the specific embodiments described above. Those skilled in the art will readily appreciate that many other alternatives to the intelligent lawn mower of the present invention exist without departing from the principles and scope of the present invention. The scope of protection of the present invention shall be determined by the claims.
