Description

Technical Field

[0001] This invention relates to the technical field of lawn mowing, and particularly to a gardening tool. Background Technology

[0002] Garden tools used for mowing lawns require adjustable mowing heights to suit different terrains. Currently, most lawn mowing tools adjust their height manually via a height adjustment handle located on the base. Users typically move the tool forward using the handle on the base, and to adjust the height, they must walk from the handle to the height adjustment handle, then back to the handle to continue mowing. When working on lawns with complex weed conditions, this process of repeatedly turning the tool on and off may be necessary, reducing efficiency, increasing workload, and extending the overall time required for the process. Summary of the Invention

[0003] The main objective of this invention is to provide a garden tool that addresses the technical problem of low efficiency in adjusting the cutting height during the operation of garden tools used for mowing lawns.

[0004] To achieve the above objectives, the garden tool proposed in this invention includes: a base, a power component housed in the base, a control component electrically connected to the power component, a cutting component connected to the power component, and an operating component connected to the base. The operating component includes an operating element for user operation and a connecting rod connecting the operating element and the base. The garden tool is characterized by including a detection component for acquiring information about the surrounding environment of the garden tool. The garden tool includes a first working mode and a second working mode. In the first working mode, the control component controls the cutting height of the cutting component based on the operating state of the operating element. In the second working mode, the control component controls the cutting height of the cutting component based on the surrounding environment information detected by the detection component.

[0005] In one embodiment, the cutting component is fixed to the base, and the garden tool includes a height adjustment component fixed to the base. The height adjustment component, the control component, and the operating element are communicatively connected. The control component controls the movement of the height adjustment component based on the operating state of the operating element to adjust the cutting height of the cutting component.

[0006] In one embodiment, the height adjustment component includes a connecting rod connected to the base, a drive motor fixed to the base or the connecting rod, and a transmission component connected to the drive motor. The control component controls the rotation of the drive motor based on the operating state of the operating component and drives the connecting rod to move through the transmission component, thereby adjusting the cutting height of the cutting component.

[0007] In one embodiment, the operating component includes a housing connected to the connecting rod and an operating element connected to the housing. The operating element includes an adjustment knob and a start / stop button. The adjustment knob is used to transmit a height adjustment operation command to the control component to control the cutting height. The start / stop button is used to transmit a start / stop operation command to the control component to control the start / stop of the power component.

[0008] In one embodiment, the operating element further includes an indicator for outputting height information of the cutting assembly, the indicator being configured as a display screen or a plurality of indicator lights.

[0009] In one embodiment, the housing includes a first operating area and a second operating area, which are arranged at an angle to each other. The second operating area faces the user. The adjustment knob and the start / stop button are located in the first operating area, and the indicator is located in the second operating area.

[0010] In one embodiment, the operating component includes a housing connected to the connecting rod and an operating element connected to the housing. The operating element includes a display module fixed to the housing. The display module includes a first touch key, a second touch key, and an indicator. The first touch key and the second touch key are used to transmit height adjustment operation commands to the control component, and the indicator is used to output the height information of the cutting component.

[0011] In one embodiment, the detection component includes a grass depth detector located on the side of the base away from the operating component, for detecting grass depth information in the direction of the garden tool's movement; the operating component also includes a grass depth adjuster with at least two grass depth settings; wherein, in the second working mode, the control component controls the cutting height based on the grass depth information and the grass depth setting of the grass depth adjuster.

[0012] In one embodiment, the detection component further includes an obstacle detector disposed on the side of the base away from the operating component, for detecting obstacle information in the direction of travel of the gardening tool; wherein, in the first working mode, the obstacle detector, in conjunction with the control component, controls the cutting height and the start and stop of the power component; in the second mode, the obstacle detector and the grass depth detector, in conjunction with the control component, control the cutting height and the start and stop of the power component.

[0013] In one embodiment, the operating element further includes a mode switching key, which is used to switch between the first operating mode and the second operating mode.

[0014] The technical solution of this invention transmits operation commands to the control component via an operating element, and the control component controls the cutting height of the cutting component. Compared to the commonly used method of manually adjusting the cutting height using a height adjustment handle, using electrical signals to adjust the cutting height reduces the user's labor intensity. Furthermore, by electrically connecting the operating element to the control component, and the control component to the power component, the cutting height of the cutting component is adjusted, avoiding repeated start-up and height adjustments during lawn mowing operations. This not only further improves the safety of lawn mowing operations but also increases work efficiency. Attached Figure Description

[0030] This invention proposes a garden tool.

[0031] Please see Figure 1 , Figure 2 , Figure 3 In one embodiment of the present invention, the garden tool includes: a base 100, a power component 200 housed in the base, a control component 600 electrically connected to the power component, a cutting component 300 connected to the power component, and an operating component 400 connected to the base. In this embodiment, the base 100 serves as the foundation of the entire garden tool, used to fix the power component 200, the operating component 400, the control component 600, etc. The operating component 400 includes an operating element 420 for user operation and a connecting rod 410 connecting the operating element and the base. The garden tool includes a detection component 500 for acquiring information about the surrounding environment of the garden tool. The detection component 500 is fixedly installed around the base 100 and transmits the detected surrounding environment information to the control component 600. The control component 600 can be located either in the base 100 or in the operating component 400; the present invention does not impose a specific limitation on this. The garden tool includes a first working mode and a second working mode. In the first working mode, the control component controls the cutting height of the cutting component based on the operating state of the operating component. In the second working mode, the control component controls the cutting height of the cutting component based on the surrounding environment information detected by the detection component.

[0032] The cutting component 300 is fixed to the base. The garden tool includes a height adjustment component 700 fixed to the base. The height adjustment component, the control component 600, and the operating component 420 are communicatively connected. The control component controls the movement of the height adjustment component based on the operating state of the operating component to adjust the cutting height of the cutting component.

[0033] The power unit 200 is connected to the cutting unit 300 to provide power for the cutting unit 300 to mow the lawn. The cutting unit 300 is used to mow the lawn. One end of the connecting rod 410 of the operating unit 400 is fixed to the base 100, and an operating element 420 is provided at the other end of the connecting rod 410. In this way, the user can push the operating unit 400 to move the gardening tool forward to perform lawn mowing operations.

[0034] In the first working mode, the user can input operation commands through the operation component 420 to control the cutting height of the cutting component 300; in the second working mode, the control component controls the cutting height of the cutting component 300 based on the surrounding environment information detected by the detection component 500.

[0035] It should be noted that the base 100 of the garden tool is fixedly equipped with a front wheel axle assembly 110 and a rear wheel axle assembly 120 at the front and rear, respectively. The front wheel axle assembly 110 and the rear wheel axle assembly 120 are used to enable the garden tool to move on the ground.

[0036] Optionally, the connection between the connecting rod 410 of the operating component 400 and the base 100 is a movable connection. In the first working mode, the connecting rod 410 and the base 100 are in an extended state. The user can push the operating component 400 to move the garden tool forward and input operating commands through the operating element 420 to control the cutting height of the cutting component 300. In the second working mode, the connecting rod 410 and the base 100 can be in a closed state. The control component 600 controls the self-movement of the garden tool and the cutting height of the cutting component 300 according to the detection component 500. That is, in the second mode, the garden tool can perform lawn mowing operations on its own. By closing the connecting rod 410, it is possible to prevent the operating component 400 from damaging the surrounding objects when the garden tool is performing lawn mowing operations on its own. It should be noted that the garden tool includes a self-propelled power component, which is located on the base 100 and connected to the front wheel axle assembly 110 and / or the rear wheel axle assembly 120 for driving the garden tool to move on its own.

[0037] The communication connection between the operating element 420 and the control component 600 includes wireless and wired connections. If a wireless connection is used, the operating element 420 can be detachably connected and fixed to the connecting rod 410.

[0038] Further, please refer to Figure 4 , Figure 5 In one embodiment, the garden tool further includes a height adjustment component 700, which includes a connecting rod 730 connected to the base, a drive motor 710 fixed to the base or the connecting rod, and a transmission component 720 connected to the drive motor. The control component 600 controls the drive motor 710 to rotate based on the operating state of the operating component 420 and drives the connecting rod 730 to move through the transmission component 720, thereby adjusting the cutting height of the cutting component.

[0039] Furthermore, the drive motor 710 is provided with a power output end; the transmission component 720 includes a first gear 721, a second gear 722, and a transmission shaft 723; the first gear 721 is located at the power output end of the drive motor 710, the second gear 722 meshes with the first gear 721, the second gear is fixed to the transmission shaft 723, and the transmission shaft 723 is rotatably connected to the connecting rod 730, thereby transmitting driving force to the connecting rod, causing the connecting rod to move forward or backward, thus lowering or raising the cutting assembly 300. In addition, a gearbox can be provided at the power output end of the drive motor to transmit power to the transmission shaft, and further to the connecting rod, thereby improving the smoothness of power transmission.

[0040] In this embodiment, the drive motor 710 is equipped with a signal receiving end, which is communicatively connected to the control component 600 and used to receive the height adjustment signal sent by the control component 600. After the user inputs an operation command through the operation component 420, the operation component 420 transmits the operation command to the control component 600. Based on the operation command, the control component 600 sends a corresponding height adjustment signal to the height adjustment component 700. After receiving the height adjustment signal, the height adjustment component 700 performs a height adjustment action based on the height adjustment signal, thereby raising or lowering the cutting component 300 to the corresponding cutting height.

[0041] Optionally, when the control component 600 controls the height adjustment component 700 to perform a lifting adjustment action on the cutting component 300, the drive motor 710 drives the first gear 721 to reverse according to the height adjustment signal sent by the control component 600; when the control component 600 controls the height adjustment component 700 to perform a lowering adjustment action on the cutting component 300, the drive motor 710 drives the first gear 721 to rotate forward according to the height adjustment signal sent by the control component 600.

[0042] Understandably, when the power output end of the drive motor 710 drives the first gear 721 to rotate forward, the first gear 721 drives the second gear 722 to rotate in reverse. The second gear 722 then drives the connecting rod 730 to descend through the transmission shaft 723, thereby reducing the height of the cutting assembly 300. Similarly, when the power output end of the drive motor 710 drives the first gear 721 to rotate in reverse, the first gear 721 drives the second gear 722 to rotate forward. The second gear 722 then drives the connecting rod 730 to rise through the transmission shaft 723, thereby increasing the height of the cutting assembly 300.

[0043] Optionally, the connecting rod 730 includes a first connecting rod 731 and a second connecting rod 732. One end of the first connecting rod 731 is connected to the front wheel axle assembly 110 disposed on the base 100, and the other end is provided with a first connecting hole and a second connecting hole. The first connecting hole is fixedly connected to the drive shaft 723, and the second connecting hole is connected to one end of the second connecting rod 732. The other end of the second connecting rod 732 is connected to the rear wheel axle assembly 120. In this way, when the first gear rotates in reverse or forward, the second connecting hole will move away from or towards the base 100 accordingly, thereby raising or lowering the cutting assembly 300.

[0044] Further, please refer to Figure 1 , Figure 2 , Figure 6In one embodiment, the operating component 400 includes a housing 430 connected to the connecting rod 410 and an operating member 420 connected to the housing. The operating member 420 includes an adjustment knob 421 and a start / stop button 422, which are disposed on the outer surface of the housing 430. The adjustment knob 421 is used to transmit a height adjustment operation command to the control component to control the cutting height. The start / stop button 422 is used to transmit a start / stop operation command to the control component to control the start and stop of the power component.

[0045] Optionally, the adjustment knob 421 has at least two positions, which transmit different height adjustment operation commands to the control component 600 depending on the position. In this way, the user can control the cutting height by operating the adjustment knob 421 to different positions.

[0046] Optionally, after receiving the height adjustment operation command transmitted by the operation component 420, the control component 600 compares the cutting height corresponding to the operation command with the current cutting height of the cutting component 300, and then adjusts the cutting height of the cutting component 300 according to the comparison result. Understandably, if the cutting height corresponding to the operation command is less than the current cutting height of the cutting component 300, the control component 600 controls the cutting component 300 to descend; similarly, if the cutting height corresponding to the operation command is greater than the current cutting height of the cutting component 300, the control component 600 controls the cutting component 300 to rise.

[0047] For example, suppose the adjustment knob 421 has four positions: lower, low, high, and higher, corresponding to cutting heights of 50 mm, 100 mm, 150 mm, and 200 mm, respectively. When the user pushes the adjustment knob 421 to switch from the lower to the higher position, the adjustment knob 421 transmits a height adjustment operation command of 150 mm to the control component 600. The control component 600 compares the cutting height corresponding to this height adjustment operation command with the current cutting height of the cutting component 300, and finds that the cutting height of 150 mm corresponding to the height adjustment operation command is 100 mm greater than the current cutting height of 50 mm of the cutting component 300. Then, the control component 600 controls the height adjustment component 700 to raise the cutting component 300 by 100 mm.

[0048] Optionally, the start / stop button 422 has two states: pressed and released. When the start / stop button 422 is in the pressed state, it transmits an operation command to start the power component 200 to the control component 600. After receiving the operation command, the control component 600 controls the power component 200 to turn on the power. When the start / stop button 422 is in the released state, it transmits an operation command to turn off the power component 200 to the control component 600. After receiving the operation command, the control component 600 controls the power component 200 to turn off the power.

[0049] In another optional implementation, the operation component 400 includes a housing 430 connected to the connecting rod 410 and an operation member 420 connected to the housing. The operation member 420 includes a display module 423 fixed to the housing 430. The display module 423 includes a first touch key 423a, a second touch key 423b, and an indicator 424. The first touch key 423a, the second touch key 423b, and the indicator 424 are disposed on the outer surface of the housing 430 of the operation component 400 and are arranged on the same plane.

[0050] The first touch key 423a and the second touch key 423b are used to transmit height adjustment operation commands to the control component. The first touch key 423a is used to generate a height adjustment command to raise the height, and the second touch key 423b is used to generate a height adjustment command to lower the height.

[0051] The indicator 424 is used to output the height information of the cutting component 300. The indicator 424 is configured as a display screen 424a or several indicator lights 424b. The display screen 424a is used to output the height information of the cutting component 300, and the indicator lights are used to display preset height adjustment commands.

[0052] In this embodiment, the height adjustment command generated by the first touch key 423a is a command to raise the cutting component 300 by a preset height. Each time the first touch key 423a generates a height adjustment command, the control component 600 controls the height adjustment component 700 to raise the cutting component 300 by one movement, and the height raised each time is consistent until the height adjustment component 700 raises the cutting component 300 to its maximum height. Similarly, the height adjustment command generated by the second touch key 423b is a command to lower the cutting component 300 by a preset height. Each time the second touch key 423b generates a height adjustment command, the control component 600 controls the height adjustment component 700 to lower the cutting component 300 by one movement, and the height lowered each time is consistent until the height adjustment component 700 lowers the cutting component 300 to its minimum height.

[0053] For example, assuming that the height adjustment command generated by the first touch key 423a is a 10 mm height adjustment command, when the user clicks the first touch key 423a twice, the first touch key 423a generates two 10 mm height adjustment commands and transmits them to the control component 600. The control component 600 sends two 10 mm height adjustment signals to the height adjustment component 700 to control the height adjustment component 700 to perform a 20 mm height adjustment action on the cutting component 300.

[0054] Optionally, the preset height adjustment command generated by the indicator light 424b is used to control the height adjustment component 700 to adjust the cutting component 300 to a preset height, such as 30 mm, 45 mm, 50 mm, 65 mm, 80 mm, 100 mm, etc.

[0055] It should be noted that, for the adjustment knob 421 and the display module 423, the operating component 420 may only have the adjustment knob 421, or only have the display module 423, or may have both the adjustment knob 421 and the display module 423.

[0056] Optionally, the housing 430 includes a first operating area 431 and a second operating area 432, which are arranged at an angle to each other. The second operating area faces the user. The adjustment knob 421 and the start / stop button 422 are located in the first operating area, and the indicator 424 is located in the second operating area.

[0057] Optionally, the operating component 420 also includes a speed control knob 427, which is located on the outer surface of the operating component 420. The adjustment knob 421, start / stop button 422, and speed control knob 427 of the operating component 420 are arranged sequentially from left to right in the first operating area 431. It should be noted that the user can input a self-propelled speed adjustment command through the speed control knob 427, which then transmits the command to the control component 600. The control component 600 controls the self-propelled speed of the garden tool according to the command. Understandably, the control component 600 is communicatively connected to the speed control knob 427 and the self-propelled power component. In other words, the user can control the self-propelled speed of the garden tool through the operating component 420.

[0058] Optionally, the operating component 420 further includes a mode switching key 425, which is located on the outer surface of the housing 430 of the operating component 420. The mode switching key 425 is used to switch between the first working mode and the second working mode. This design aims to allow the user to switch the working mode of the garden tool using the operating component 420. The mode switching key 425 can be located in the second operating area 432 of the operating component 420.

[0059] The mode switching key 425 can include two states: pressed and released. When the mode switching key 425 is in the released state, it transmits the working mode configuration signal corresponding to the first working mode to the control component 600. When the control component 600 receives the working mode configuration signal, it controls the cutting height of the cutting component 300 according to the operation command transmitted by the operating component 420. When the mode switching key 425 is in the pressed state, it transmits the working mode configuration signal corresponding to the second working mode to the control component 600. When the control component 600 receives the working mode configuration signal, it controls the cutting height of the cutting component 300 according to the surrounding environment information obtained by the detection component 500.

[0060] The purpose of this design is to facilitate user operation. When the user pushes the garden tool to perform lawn mowing operations through the operating component 400, they can operate the adjustment knob 421 and speed control knob 427 located in the first operating area 431 of the housing 430 of the operating component 420, as well as the display module 423 and mode switching key 425 located in the second operating area 432, simply by using their thumb.

[0061] In the technical solution provided in this embodiment, the operation command is transmitted to the control component 600 through the operating component 420, and the control component 600 controls the cutting height of the cutting component 300. Compared with the commonly used method of manually adjusting the height of the cutting component 300 using a height adjustment handle, using an electrical signal to adjust the cutting height of the cutting component 300 reduces the user's labor intensity. Furthermore, by communicating with the control component 600 and the power component 200 through the operating component 400, the cutting height of the cutting component 300 can be adjusted, avoiding the need to repeatedly turn the machine off, adjust the height, and turn it on during lawn mowing operations. This not only further improves the safety of lawn mowing operations but also increases the efficiency of the operation.

[0062] Please continue to refer to Figure 7 In one embodiment of the present invention, the detection component 500 includes a grass depth detector, which is located on the side of the base 100 away from the operating component 400, and is used to detect grass depth information in the direction of movement of the gardening tool.

[0063] In this embodiment, the operating component 420 further includes a grass depth adjustment component 426. The grass depth adjustment component 426 functions similarly to the adjustment knob 421 in the first working mode, and the grass depth adjustment component 426 has at least two grass depth settings. Alternatively, the grass depth adjustment component 426 is located in the first operating area 431 of the housing 430 of the operating component 420, symmetrically arranged with the adjustment knob 421 on the left and right sides of the first operating area 431. This design aims to prevent the user from accidentally operating the adjustment knob 421 while operating the grass depth adjustment component 426.

[0064] In the second working mode, the control component 600 controls the cutting height based on the grass depth information and the grass depth setting of the grass depth adjuster 426.

[0065] As another implementation, the grass depth adjustment component 426 can also be the first touch key 423a and the second touch key 423b in the display module 423. By operating the first touch key 423a and the second touch key 423b, the grass depth can be adjusted to different grass depth levels, and different grass depth configuration commands can be transmitted to the control component 600, so that the control component 600 can control the height adjustment component 700 to perform corresponding actions of raising or lowering the cutting component 300 according to the grass depth information and grass depth configuration information.

[0066] For example, assume that the grass depth settings include 30 mm, 60 mm, and 90 mm settings. When the user operates the grass depth adjuster 426 to the 60 mm setting, the grass depth adjuster 426 transmits 60 mm grass depth configuration information to the control component 600, so that the control component 600 can control the height adjustment component 700 to perform the corresponding actions of raising or lowering the cutting component 300 based on the grass depth information and the 60 mm grass depth configuration information.

[0067] Optionally, the control component 600 controls the height adjustment component 700 to adjust the cutting height based on grass depth information and grass depth configuration information. The height adjustment component 700 adjusts the cutting component 300 by raising or lowering it according to the undulations of the terrain in the garden tool's working area. In this way, when the garden tool is working on complex terrain, it can ensure that the lawn has a consistent grass depth after the garden tool has worked.

[0068] Optionally, the detection component 500 includes a grass depth detector, which is located on the side of the base away from the operating component 400, and is used to detect grass depth information in the direction of movement of the gardening tool.

[0069] Grass depth detectors are either ultrasonic sensors or lidar. In essence, a grass depth detector transmits and receives reflected signals, calculating the height of the lawn based on the signal propagation time or phase difference, thereby obtaining information about the grass depth in the direction in which gardening tools are moving.

[0070] As an alternative implementation, the detection component 500 further includes an obstacle detector located on the side of the base 100 away from the operating component 400, for detecting obstacle information in the direction of travel of the gardening tool. In the first operating mode, the obstacle detector, in conjunction with the control component 600, controls the cutting height and the start / stop of the power component 200; in the second mode, the obstacle detector and the grass depth detector, in conjunction with the control component 600, control the cutting height and the start / stop of the power component 200.

[0071] In this embodiment, in the second operating mode, the obstacle detector sends the detected obstacle information to the control component 600. The control component 600, based on the obstacle information, determines whether the mowing height, determined by the grass depth information and grass depth configuration information, can successfully pass through the target obstacle. Then, based on the determination result, it determines whether to send a height adjustment signal to the height adjustment component 700. Understandably, when the determination result is that the target obstacle can be passed, the control component 600 does not send a height adjustment signal to the height adjustment component 700; when the determination result is that the target obstacle cannot be passed, the control component 600, based on the obstacle information, sends the corresponding height adjustment signal to the height adjustment component 700, controlling the height adjustment component 700 to raise the cutting component 300, ensuring that the gardening tool can successfully pass through the target obstacle.

[0072] Optionally, the obstacle information detected by the obstacle detector includes the distance between the garden tool and the obstacle, and the height of the obstacle. Specifically, in the first and second operating modes, when the distance is less than or equal to a preset distance value, and the height of the obstacle is greater than or equal to a preset height value, the control component 600 sends a stop signal to the power component 200 to stop the operation of the cutting component 300.

[0073] Furthermore, when the distance value is less than or equal to the preset distance value and the height value of the obstacle is greater than or equal to the preset height value, the control component 600 sends a stop signal to the self-propelled power component to prevent the garden tool from continuing to move in the direction of the obstacle.

[0074] This enables obstacle avoidance during the operation of garden tools, ensuring that the cutting component 300 is not damaged by obstacles, and further improving the safety of garden tool operations.

[0075] Optionally, the obstacle detector includes an information acquisition element and an information processing element. The information acquisition element is used to acquire image information of the direction of movement of the garden tool, and the information processing element is used to determine the distance between the garden tool and the obstacle, as well as the height of the obstacle, based on the image information.

[0076] In the technical solution provided in this embodiment, the detection component 500 acquires the surrounding environment information of the garden tool and sends the acquired surrounding environment information to the control component 600. The control component 600 controls the height adjustment component 700 to adjust the cutting height of the cutting component 300 according to the surrounding environment information, thereby realizing the adaptive adjustment of the cutting height of the garden tool.

Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
