Description

Technical Field

[0001] This application relates to the field of lawnmowers, and in particular to a lawnmower mechanism and lawnmower device. Background Technology

[0002] Lawn mowers are mainly used for garden trimming, lawn mowing, urban street trimming, greening and scenic spot trimming, field trimming, field weeding, especially for the maintenance of lawns and turf in parks, football fields, private gardens, and other grass-using areas such as agricultural, forestry and livestock farms.

[0003] In implementing the embodiments of this application, the inventors discovered that a lawnmower includes a lawnmower body, a blade disc, and a trimming rope. The blade disc is mounted on the lawnmower body, and the trimming rope is mounted on the blade disc. The blade disc rotates relative to the lawnmower body, thereby driving the trimming rope to cut grass. However, in actual use, when trimming lawns or turf in limited spaces such as yards, the lawnmower cannot trim the edges or corners of lawns or turf in limited spaces because the rotation radius of its trimming rope is fixed. Summary of the Invention

[0004] The embodiments of this application can improve the current situation where lawnmowers cannot correct the corners of lawns or turf in limited spaces such as courtyards because the rotation radius of their mowing ropes is fixed.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A mowing mechanism is provided, comprising a mowing main unit, a mowing assembly, and a detection assembly. The mowing main unit is equipped with a control module. The mowing assembly includes a drive module and a trimming rope. The drive module is mounted on the mowing main unit, and one end of the trimming rope is connected to the drive module. The drive module is used to drive the trimming rope to rotate and to extend or retract the trimming rope. The drive module is electrically connected to the control module. The detection assembly includes a detection switch and a detection swing arm. Both the detection switch and the detection swing arm are mounted on the mowing main unit. The detection swing arm is closer to the trimming rope than the detection switch, and the detection swing arm is rotatable relative to the mowing main unit. When the trimming rope rotates, it triggers the detection swing arm to rotate, which in turn triggers the detection switch. The detection switch sends a signal to the control module, and the drive module fixes the length of the trimming rope. Alternatively, if the trimming rope does not trigger the detection swing arm to rotate, the drive module extends or retracts the length of the trimming rope until it can trigger the detection swing arm to rotate, and then the drive module fixes the length of the trimming rope.

[0006] Optionally, the drive module includes a trimmer head and a drive motor. The lawn mower has a receiving cavity, one end of the drive motor is received in the receiving cavity, the trimmer head is installed on the other end of the drive motor, the drive motor is used to drive the trimmer head to rotate, the trimmer rope is installed on the trimmer head, and the trimmer head is used to extend or retract the trimmer rope.

[0007] Optionally, when the hay-trimming rope rotates, the distance between the hay-trimming rope and the rotation axis of the hay-trimming head is D1, and the distance between the detection swing arm and the rotation axis of the hay-trimming head is D2, where D1 ≥ D2.

[0008] Optionally, the detection component includes a mounting slider that is movably mounted on the lawn mower and can move relative to the lawn mower in a preset direction parallel to the rotation direction of the mowing head. The detection switch and the detection swing arm are mounted on the mounting slider, and along the preset direction, the detection swing arm is closer to the mowing rope relative to the detection switch.

[0009] Optionally, the detection component further includes an electromagnetic push rod, one end of which is connected to the mounting slider and the other end is fixed to the mowing host. The electromagnetic push rod is electrically connected to the control module and is used to drive the mounting slider to move closer to or away from the rotating mowing rope along the preset direction.

[0010] Optionally, when the straw rope rotates, the control module controls the electromagnetic push rod to periodically reciprocate along the preset direction.

[0011] Optionally, the detection assembly further includes a rotating shaft and a reset component. The rotating shaft is mounted on the mounting slider, and the detection swing arm is rotatably mounted on the rotating shaft. One end of the reset component is mounted on the mounting slider, and the other end of the reset component is fixed to the detection swing arm. The reset component is used to keep the detection swing arm straight along the preset direction.

[0012] Optionally, the mounting slider is provided with a limiting part, which is located at the end of the mounting slider near the rotating end of the detection swing arm. The limiting part is used to restrict the movement of the detection swing arm away from the straw rope along the preset direction.

[0013] Optionally, the mowing mechanism is further provided with a protective baffle, which is installed on the mowing host. The protective baffle is bent, and the distance between the bent part of the protective baffle and the mowing head is D3, where D3 > D1.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a grass-cutting device, including the above-mentioned grass-cutting mechanism.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment provides a mowing mechanism, which includes a mowing main unit, a mowing assembly, and a detection assembly. The mowing main unit is equipped with a control module. The mowing assembly includes a drive module and a trimming rope. The drive module is mounted on the mowing main unit, and one end of the trimming rope is connected to the drive module. The drive module is used to drive the trimming rope to rotate and to extend or retract the trimming rope. The drive module is electrically connected to the control module. The detection assembly includes a detection switch and a detection swing arm. Both the detection switch and the detection swing arm are mounted on the mowing main unit. The detection swing arm is closer to the trimming rope than the detection switch, and the detection swing arm can rotate relative to the mowing main unit. When the trimming rope rotates, it triggers the detection arm to rotate, which in turn triggers the detection switch. The detection switch sends a signal to the control module, and the drive module fixes the length of the trimming rope. Alternatively, if the trimming rope does not trigger the detection arm to rotate, the drive module extends or retracts the trimming rope until it can trigger the detection arm to rotate, and then fixes the length of the trimming rope. With this structure, when the trimming rope touches the edge of a lawn or turf in a confined space such as a yard, its rotation speed slows down, allowing the control module to control the trimming head to retract the rope and correct any remaining grass or turf.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0024] This application provides a lawn mowing device, which includes a mowing mechanism 100, a power supply mechanism (not shown in the figure), and a walking mechanism (not shown in the figure). The power supply mechanism is installed on the mowing mechanism 100, and the walking mechanism is installed below the mowing mechanism 100. The power supply mechanism provides electrical energy to the mowing mechanism 100 and / or the walking mechanism, and can be electrically connected to and charged with other charging devices via cables or plugs. The walking mechanism can be a non-powered wheel set or a power-assisted wheel set, i.e., a walking mechanism propelled by human power, facilitating the trimming of small lawns or grasslands and reducing the manufacturing cost of the lawn mowing device. Alternatively, the walking mechanism can be a motor-driven wheel set, i.e., controlled by a control module within the mowing mechanism 100 to achieve automatic mowing. It can be understood that the control module can control the walking mechanism's movement according to a pre-planned route, or according to user movement commands, or by collecting and processing actual environmental information captured by other sensors on the mowing mechanism 100, which is then processed by the control module to enable it to control the walking mechanism's movement.

[0025] For the aforementioned lawnmower 100, please refer to Figures 1 to 3 It shows a schematic diagram of a lawn mowing mechanism 100 provided in one embodiment of this application, a schematic diagram of the electrical connection relationship of a lawn mowing mechanism 100 provided in one embodiment of this application, and a schematic diagram of the lawn mowing mechanism 100 provided in one embodiment of this application. Figure 1Enlarged view of part A. The mowing mechanism 100 includes a mowing main unit 10, a mowing assembly 20, and a detection assembly 30. The mowing main unit 10 is equipped with a control module 11. It is understood that the mowing main unit 10 also includes other electronic components to assist the control module 11 in performing mowing work. The mowing assembly 20 includes a drive module 21 and a trimming rope 22. The drive module 21 is mounted on the mowing main unit 10, and one end of the trimming rope 22 is connected to the drive module 21. The drive module 21 is used to drive the trimming rope 22 to rotate, and to extend or retract the trimming rope 22. The drive module 21 is electrically connected to the control module 11. The trimming rope 22 is made of nylon rope. Nylon rope is lighter, has a low coefficient of friction, is easy to process, and has heat resistance, wear resistance, chemical resistance, and self-lubricating properties. The detection assembly 30 includes a detection switch 31 and a detection swing arm 32, both mounted on the lawn mower 10. The detection swing arm 32 is closer to the mowing rope 22 than the detection switch 31, and can rotate relative to the lawn mower 10. The detection switch 31 is electrically connected to the control module 11, allowing the control module 11 to interact with the detection switch 31. Specifically, the detection swing arm 32 is generally L-shaped, and its swing angle is between 0° and 90°. It is understood that the axis of rotation of the detection swing arm 32 is perpendicular to the axis of rotation of the mowing rope 22. In this embodiment, the rotation center of the detection swing arm 32 is located at its end; in other embodiments, the rotation center may be located in the middle of the detection swing arm 32. When the trimming rope 22 rotates, it triggers the rotation of the detection swing arm 32, which in turn triggers the detection switch 31. The detection switch 31 sends a signal to the control module 11, which then controls the drive module 21 to fix the length of the trimming rope 22. Alternatively, if the trimming rope 22 does not trigger the rotation of the detection swing arm 32, the drive module 21 extends or retracts the length of the trimming rope 22 until it can trigger the rotation of the detection swing arm 32, at which point the drive module 21 fixes the length of the trimming rope 22. Specifically, when the detection swing arm 32 is whipped by the trimming rope 22, it rotates and triggers the detection switch 31. The detection switch 31 then sends a signal back to the control module 11. If the control module 11 recognizes that the rotation length of the trimming rope 22 is within an acceptable range and that the speed of the trimming rope 22 has not decreased due to touching any corners, the drive module 21 fixes the length of the trimming rope 22. Conversely, if the control module 11 detects that the rotation length of the straw rope 22 exceeds the acceptable range, the control module 11 controls the drive module 21 to perform a winding action on the straw rope 22 until the detection swing arm 32 is struck again by the straw rope 22, triggering the detection switch 31. Upon receiving feedback, the control module 11 controls the drive module 21 to stop the winding action. It should be noted that the acceptable range mentioned in this embodiment is the length of the straw rope 22 during rotation, determined based on the actual environment; that is, the acceptable range can change in different environments.

[0026] For the aforementioned driver module 21, please refer to Figure 1 The driving module 21 includes a trimming head 211 and a drive motor 212. The mowing host 10 is provided with a receiving cavity 12. One end of the drive motor 212 is received in the receiving cavity 12, and the trimming head 211 is installed on the other end of the drive motor 212. The drive motor 212 is used to drive the trimming head 211 to rotate. The trimming rope 22 is installed on the trimming head 211, and the trimming head 211 is used to extend or retract the trimming rope 22. It can be understood that other snap-fit ​​structures and buffer structures can also be provided inside the mowing host 10. The snap-fit ​​structures and buffer structures are located in the receiving cavity 12, thereby snapping and fixing the drive motor 212, and at the same time playing a buffering role to prevent the centrifugal force of the drive motor 212 from causing the mowing mechanism 100 to be unstable in operation.

[0027] Furthermore, when the mowing rope 22 rotates, the distance between the mowing rope 22 and the rotation axis of the mowing head 211 is D1, and the distance between the detection arm 32 and the rotation axis of the mowing head 211 is D2, where D1 ≥ D2. That is, the detection component 30 is installed outside the mowing host 10, and the shortest length of the mowing rope 22 should be greater than D2, thereby ensuring that the detection component 30 can detect the current length of the mowing rope 22.

[0028] For the detection component 30 mentioned above, please refer to Figure 1 and Figure 3 The detection component 30 includes a mounting slider 33, which is movably mounted on the mower unit 10. The mounting slider 33 can move relative to the mower unit 10 in a preset direction, which is parallel to the rotation direction of the mowing head 211. A detection switch 31 and a detection swing arm 32 are mounted on the mounting slider 33. Along the preset direction, the detection swing arm 32 is closer to the mowing rope 22 relative to the detection switch 31. It is understood that the mowing rope 22 will have an angle with its rotation axis due to different rotation speeds, resulting in a displacement difference of the mowing rope 22 in the preset direction at different rotation speeds. When facing different environments, the rotation speed of the mowing rope 22 can be adjusted. In order to measure whether the rotation speed or length of the mowing rope 22 is within an acceptable range, the mounting slider 33 can be adjusted along the preset direction, thereby adjusting the distance between the detection swing arm 32 and the mowing rope 22.

[0029] Furthermore, the detection component 30 also includes an electromagnetic push rod 34. One end of the electromagnetic push rod 34 is connected to the mounting slider 33, and the other end is fixed to the lawnmower host 10. The electromagnetic push rod 34 is electrically connected to the control module 11. The electromagnetic push rod 34 is used to drive the mounting slider 33 towards or away from the rotating mowing rope 22 in a preset direction. It is understood that in some other embodiments, a servo motor, cylinder driver, or other driving mechanism may also be used. And because the electromagnetic push rod 34 is electrically connected to the control module 11, the electromagnetic push rod 34 can adjust the position of the mounting slider 33 in the preset direction according to the instructions of the control module 11.

[0030] Furthermore, when the mowing rope 22 rotates, the control module 11 controls the electromagnetic push rod 34 to periodically reciprocate along a preset direction. It can be understood that when the control module 11 controls the drive motor 212 to rotate, the control module 11 controls the electromagnetic push rod 34 to push the mounting slider 33 to reciprocate at a fixed cycle; when the drive motor 212 stops rotating, the electromagnetic push rod 34 moves the mounting slider 33 to a position away from the mowing rope 22, thus facilitating the next start. In other words, the control module 11 controls the electromagnetic push rod 34 to periodically reciprocate along a preset direction, throughout the entire mowing operation of the mowing mechanism 100, thereby enabling the detection component 30 to automatically detect the rotation length of the mowing rope 22, forming a closed-loop feedback.

[0031] For the detection component 30 in the embodiments of this application, please refer to... Figure 3 The detection assembly 30 also includes a rotating shaft 35 and a reset member 36. The rotating shaft 35 is mounted on the mounting slider 33, and the detection swing arm 32 is rotatably mounted on the rotating shaft 35. One end of the reset member 36 is mounted on the mounting slider 33, and the other end of the reset member 36 is fixed to the detection swing arm 32. The reset member 36 is used to keep the detection swing arm 32 straight in a preset direction. Specifically, the reset member 36 includes a spring, an electromagnetic push rod 34, or a reset torsion spring 361. In this embodiment, a reset torsion spring 361 is used. The reset torsion spring 361 is wound around the rotating shaft 35, and both ends of the reset torsion spring 361 abut against the mounting slider 33 and the detection swing arm 32, respectively, thereby keeping the detection swing arm 32 straight in a preset direction, so that the detection swing arm 32 can be reset regardless of whether the detection switch 31 is triggered.

[0032] Furthermore, a trigger baffle 37, which can rotate relative to the mounting slider 33, is also provided at the detection switch 31. The detection swing arm 32 is arranged in an "L" shape, wherein the short side of the detection swing arm 32 is always in contact with the trigger baffle 37, so that the short side of the detection swing arm 32, the detection switch 31, and the trigger baffle 37 can form a lever structure. This allows the short side of the detection swing arm 32 to be driven to rotate in time when the long side of the detection swing arm 32 is whipped by the straw rope 22, thereby pushing the trigger baffle 37 to trigger the detection switch 31.

[0033] For the mounting slider 33 mentioned above, please refer to Figure 3 The mounting slider 33 is provided with a limiting part 331, which is located at the end of the mounting slider 33 near the rotating end of the detection swing arm 32. The limiting part 331 is used to restrict the movement of the detection swing arm 32 away from the straw rope 22 in a preset direction.

[0034] Please review the embodiments in this application. Figure 1 The mowing mechanism 100 is also equipped with a protective baffle 40, which is mounted on the mowing host 10. The protective baffle 40 is bent, and the distance between the bent part of the protective baffle 40 and the mowing head 211 is D3, where D3 > D1. Specifically, the protective baffle 40 is arranged in a curved wing shape on the side of the mowing host 10 near the mowing head 211. Multiple protective baffles 40 are provided, thereby forming a protective space through the bent part. In some other embodiments, a protective net is also provided between the protective baffles 40 to prevent other objects in the external environment from suddenly flying into the mowing rope 22 and causing damage to the equipment. At the same time, the mesh structure of the protective net itself allows air circulation, which can dissipate heat for the mowing head 211 and the drive motor 212, facilitating the operation of the mowing mechanism 100.

[0035] This application provides a lawn mowing mechanism 100, which includes a main mowing unit 10, a mowing assembly 20, and a detection assembly 30. The main mowing unit 10 is equipped with a control module 11. The mowing assembly 20 includes a drive module 21 and a trimming rope 22. The drive module 21 is mounted on the main mowing unit 10, and one end of the trimming rope 22 is connected to the drive module 21. The drive module 21 is used to drive the trimming rope 22 to rotate, and to extend or retract the trimming rope 22. The drive module 21 is electrically connected to the control module 11. The detection assembly 30 includes a detection switch 31 and a detection swing arm 32. Both the detection switch 31 and the detection swing arm 32 are mounted on the main mowing unit 10. The detection swing arm 32 is closer to the trimming rope 22 than the detection switch 31, and the detection swing arm 32 can rotate relative to the main mowing unit 10. When the mowing rope 22 rotates, it triggers the detection arm 32 to rotate, which in turn triggers the detection switch 31. The detection switch 31 sends a signal to the control module 11, and the drive module 21 fixes the length of the mowing rope 22. Alternatively, if the mowing rope 22 does not trigger the detection arm 32 to rotate, the drive module 21 extends or retracts the length of the mowing rope 22 until it can trigger the detection arm 32 to rotate, and then fixes the length of the mowing rope 22. With this structure, when the mowing rope 22 touches the edge of a lawn or turf in a limited space such as a yard, its rotation speed slows down, allowing the control module 11 to control the drive module 21 to retract the mowing rope 22 to correct any remaining grass or turf. This improves the current situation where lawnmowers, due to the fixed rotation radius of their mowing ropes 22, are unable to correct the edges of lawns or turf in limited spaces like yards.

[0036] Based on the same inventive concept, this application also provides a lawn mowing device, which includes a mowing mechanism 100, a power supply mechanism, and a walking mechanism. The power supply mechanism is installed on the mowing mechanism 100, and the walking mechanism is installed below the mowing mechanism 100. The mowing mechanism 100 has the same structure and function as the aforementioned mowing mechanism 100, and will not be described in detail here. Therefore, the lawn mowing device provided in this application can also improve the current situation where, when mowing lawns or lawns in limited spaces such as courtyards, the lawnmower's fixed rotation radius of the mowing rope 22 prevents it from correcting the edges and corners of lawns or lawns in limited spaces such as courtyards.

[0037] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
