Description

Technical Field

[0001] The utility model relates to the technical field of lawn mowers, in particular to an intelligent lawn mower. Background Art

[0002] Since the smart lawn mower can mow the lawn autonomously, it is widely used in real life. In order to enable the smart lawn mower to mow the lawn within a pre-set range, it is usually necessary to use a positioning navigation device to set a virtual boundary for the smart lawn mower.

[0003] In the process of using the positioning and navigation device to set the virtual boundary for the smart lawn mower, the hand-push bracket provided on the smart lawn mower is required to push the smart lawn mower. When the user pushes the smart lawn mower to move, the positioning and navigation device can determine the virtual boundary of the smart lawn mower when it is working by recording the walking track of the smart lawn mower. However, directly setting the hand-push bracket on the smart lawn mower will make the smart lawn mower appear very bulky.

[0004] In addition, the positioning and navigation device on the smart lawn mower is an independent device module. During use, the user not only needs to use a cable to connect the positioning and navigation device to a specific interface of the smart lawn mower, but also frequently plugging and unplugging the positioning and navigation device from the interface of the smart lawn mower will cause poor contact of the interface and reduce the service life of the smart lawn mower, thus greatly reducing the user experience when using the smart lawn mower. At present, there is no more effective solution to this technical problem. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1 , Figure 1 The present invention provides a structural diagram of an intelligent lawn mower provided in an embodiment of the present invention, wherein the intelligent lawn mower comprises: a lawn mower body 10, on which a positioning and navigation device 20 is provided, and on which a clamping frame 30 for clamping the lawn mower body 10 is also provided, and on which a roller 40 for pushing the lawn mower body 10 to walk is detachably connected, and the clamping frame 30 is detachably connected to the lawn mower body 10.

[0036] See also Figure 2 , Figure 21 is a functional block diagram of the lawn mower body. The lawn mower body 10 is provided with a main controller 100, a communication module 120, a data storage module 130, a travel drive module 110, a working drive module 140, a positioning navigation device 20 and a power supply unit 150. Among them, the main controller 100 is used to control various functional modules inside the lawn mower body 10, the positioning navigation device 20 is used to locate the real-time position of the lawn mower body 10; the data storage module 130 is used to store various operating data of the lawn mower body 10; the communication module 120 is used to communicate the lawn mower body 10 with peripheral devices; the travel drive module 110 is used to control the walking of the lawn mower body 10; and the working drive module 140 is used to drive the lawn mower body 10 to work.

[0037] The power supply unit 150 supplies power to the travel drive module 110, the working drive module 140 and the positioning navigation device 20. In addition, the lawn mower body 10 has at least two working modes. In the first working mode, the positioning navigation device 20 works, and the travel drive module 110 and the working drive module 140 do not work; in the second working mode, the positioning navigation device 20, the travel drive module 110 and the working drive module 140 work simultaneously. The main controller 100 communicates or is connected with the positioning navigation device 20, the travel drive module 110 and the working drive module 140.

[0038] The intelligent lawn mower comprises a lawn mower body 10, on which a positioning navigation device 20 and a clamping frame 30 for clamping the lawn mower body 10 are arranged, and a roller 40 for pushing the lawn mower body 10 to move is detachably connected to the clamping frame 30, and the clamping frame 30 is detachably connected to the lawn mower body 10. Figure 3 and Figure 4 , Figure 3 This is a partial schematic diagram of installing the roller on the clamping frame. Figure 4 is a cross-sectional view of the roller. Figure 4 In the illustrated roller 40 , X represents the center axis of the roller.

[0039] When the user needs to use the smart lawn mower to mow the lawn in a designated area, the user first needs to clamp the clamping frame 30 on the lawn mower body 10 and install the roller 40 on the clamping frame 30; when the clamping frame 30 is installed on the lawn mower body 10 and the roller 40 is installed on the clamping frame 30, the user can push the lawn mower body 10 to move by pushing the clamping frame 30.

[0040] Since the positioning and navigation device 20 is directly disposed on the lawn mower body 10 , the user can use the positioning and navigation device 20 disposed on the lawn mower body 10 to record the walking track of the lawn mower body 10 while pushing the lawn mower body 10 through the clamping frame 30 and the roller 40 .

[0041] With this technical support, when the user wants to set a virtual boundary for the smart lawn mower when mowing, the user can use the clamping frame 30 and the roller 40 to push the lawn mower body 10 to move within the specified area, and use the positioning and navigation device 20 on the lawn mower body 10 to record the walking trajectory of the lawn mower body 10, thereby obtaining the virtual boundary of the smart lawn mower.

[0042] When the virtual boundary of the smart lawn mower is determined, in order to ensure the flexibility and portability of the smart lawn mower in the subsequent mowing process, the clamping frame 30 and the roller 40 can be removed from the lawn mower body 10, so that the smart lawn mower body 10 can work in the designated area according to the pre-created virtual boundary.

[0043] It should be noted that when making the clamping frame 30, any tough material can be used to make the clamping frame 30 for clamping the lawn mower body 10, such as plastic, aluminum alloy, steel, etc., as long as the clamping frame 30 can clamp the lawn mower body 10, no specific limitation is made here.

[0044] In actual application, a first start button and a second start button can also be set on the lawn mower body 10. When the first start button on the lawn mower body 10 is pressed, the lawn mower body 10 is in the first working mode, the positioning and navigation device 20 is in the working state, and the walking drive module 110 and the working drive module 140 are both in the non-working state. At this time, the user pushes the clamping frame 30 to drive the lawn mower body 10 to move along the boundary route expected by the user, and the positioning and navigation device 20 records the boundary position information along the way, and uses it to establish a virtual boundary. In the process of establishing the virtual boundary, the walking drive module 110 and the working drive module 140 do not need to work, and the virtual boundary in the lawn mower body 10 is completely determined by the user.

[0045] After the clamping frame 30 and the roller 40 are removed from the lawn mower body 10, the second start button on the lawn mower body 10 is pressed, and the lawn mower body 10 is in the second working mode, and the positioning navigation device 20, the travel drive module 110 and the working drive module 140 are all in the working state. At this time, the lawn mower body 10 will automatically perform the mowing task within the range of the virtual boundary according to the virtual boundary recorded by the positioning navigation device 20.

[0046] Compared with the prior art, in the smart lawn mower provided in the present application, the positioning and navigation device is directly set on the lawn mower body, and a detachable clamping frame and roller are also set on the lawn mower body, so that when the user uses the positioning and navigation device to set a virtual boundary for the smart lawn mower, the user only needs to install the clamping frame and roller on the lawn mower body, and the user can use the positioning and navigation device on the lawn mower body to determine the virtual boundary of the smart lawn mower when it is working by pushing the lawn mower body. When the virtual boundary of the smart lawn mower is determined when it is working, the clamping frame and roller are removed from the lawn mower body, and the smart lawn mower can perform subsequent work according to the virtual boundary it has set, thus ensuring the flexibility and portability of the smart lawn mower when performing subsequent work.

[0047] In addition, since the positioning and navigation device is directly set on the lawn mower body, when the user uses the positioning and navigation device to set the virtual boundary of the smart lawn mower, it can avoid the cumbersome process of installing the positioning and navigation device on the lawn mower body and frequently plugging and unplugging the positioning and navigation device. This setting method can not only improve the convenience of users when using the smart lawn mower, but also improve the service life of the smart lawn mower. In addition, setting the positioning and navigation device directly on the lawn mower body can also reduce the structural complexity and setting cost of the smart lawn mower. Obviously, the user experience of people when using the smart lawn mower can be significantly improved through this application.

[0048] Based on the above embodiments, this embodiment further explains and optimizes the technical solution. Figure 5 , Figure 5 A structural diagram of a clamping frame provided by an embodiment of the utility model. As a preferred embodiment, the clamping frame 30 includes a handle 301, a telescopic rod 302 and an integrally formed double fork arm 303, the top of the telescopic rod 302 is connected to the center of the handle 301, the end of the telescopic rod 302 is connected to the center of the double fork arm 303, the ends of the two forks of the double fork arm 303 are respectively provided with axles 304, and the roller 40 is rotatably connected to the double fork arm 303 through the hollow structure of the axle 304.

[0049] In this embodiment, the structure of the clamping frame 30 is specifically described. The clamping frame 30 is provided with a handle 301, a telescopic rod 302 and an integrally formed double fork arm 303, the two ends of the telescopic rod 302 are respectively connected to the center of the handle 301 and the center of the double fork arm 303, the two ends of the double fork arm 303 are respectively provided with axles 304, and the roller 40 is rotatably connected to the double fork arm 303 through the hollow structure of the axle 304.

[0050] It is conceivable that after the handle 301 is provided on the clamping frame 30, the user can use the handle 301 on the clamping frame 30 to push the lawn mower body 10 to walk, which increases the convenience of the user when using the clamping frame 30. The telescopic rod 302 can be adaptively lengthened or shortened according to the actual use of the user, so that the height of the clamping frame 30 can be adapted to the height of the user. In addition, when the two ends of the telescopic rod 302 are respectively connected to the center position of the handle 301 and the center position of the double fork arm 303, the stability of the clamping frame 30 during use can be ensured.

[0051] Obviously, the technical solution provided in this embodiment can further improve the user experience when people use the clamping frame to push the lawn mower body to move.

[0052] See also Figure 6 , Figure 6 The schematic diagram of the clamping position of the clamping frame provided in the embodiment of the utility model when clamping the lawn mower body. As a preferred embodiment, the two fork arm ends of the double fork arm 303 are clamped on the body of the lawn mower body 10 through the wheel axle 304 respectively.

[0053] In practical applications, the two fork ends of the double fork arms 303 on the clamping frame 30 are clamped on the body of the lawn mower body 10 through the wheel axle 304, as long as the clamping frame 30 can clamp the lawn mower body 10 through the double fork arms 303 arranged thereon and push the lawn mower body 10 to move. For example, the clamping frame 30 can clamp the lawn mower body at the body 101 of the lawn mower body to move.

[0054] As a preferred embodiment, the two fork arm ends of the double fork arm 303 are clamped at the center positions of the two wheels 102 of the lawn mower body 10 through the wheel axle 304 respectively, and the diameter of the roller 40 is greater than the diameter of the wheel 102 .

[0055] It is understandable that since most of the weight of the lawn mower body 10 is concentrated on the wheels 102 of the lawn mower body 10, in order to ensure the stability and reliability of the clamping frame 30 when clamping the lawn mower body 10, the two fork arm ends of the double fork arm 303 on the clamping frame 30 can also be clamped at the center position of the two wheels 102 of the lawn mower body 10 through the wheel axle 304 respectively.

[0056] When the diameter of the roller 40 is greater than the diameter of the wheel 102 , it can be ensured that the clamping frame 30 can lift the lawn mower body 10 a certain distance from the ground, so that the user can push the lawn mower body 10 through the clamping frame 30 .

[0057] For details, please see Figure 7 and Figure 8 , Figure 7 The roller is installed on the clamping frame through the plug-in, and the structure diagram of the clamping frame when clamping the lawn mower body. Figure 8 for Figure 7 Exploded view of the roller, insert and the main wheel of the mower. Figure 7 In the figure, d1 represents the diameter of the wheel 102 on the lawn mower body 10 , and d2 represents the diameter of the roller 40 . The roller 40 is mounted on the axle 304 of the double fork arm 303 through the plug-in 50 .

[0058] As a preferred embodiment, the wheel 102 is connected to the motor in the lawn mower body 10 .

[0059] In actual application, the wheels 102 on the lawn mower body 10 are generally connected to the motor in the lawn mower body 10. If the walking module of the lawn mower body 10 is not started and the lawn mower body 10 is directly pushed to walk, the wheels 102 of the lawn mower body 10 will generate reverse current during the rotation process, which will damage the motor in the lawn mower body 10.

[0060] Therefore, in this embodiment, the double fork arms 303 on the clamping frame 30 need to be clamped in the wheels 102 connected to the motor on the lawn mower body 10, and the wheels 102 on the lawn mower body 10 need to be lifted by the rollers 40 with a larger diameter, so that the rollers 40 can rotate freely. This arrangement can prevent the motor in the lawn mower body 10 from being damaged, thereby relatively extending the service life of the smart lawn mower.

[0061] Obviously, the technical solution provided by this embodiment can not only ensure the flexibility and diversity of the clamping frame when clamping the lawn mower body, but also ensure the safety and reliability of the intelligent lawn mower when in use.

[0062] See also Fig. 9 and Fig.10 , Fig. 9 A schematic diagram of a roller provided by an embodiment of the utility model being connected to the axle on the double fork arm through a plug-in, Fig.10 for Fig. 9 As a preferred embodiment, the center of the roller 40 is connected to the hollow structure of the axle 304 through the plug-in 50, and the hollow structure of the axle 304 is provided with threads. The plug-in 50 includes a locking button 501 with threads and a clamping block 502 used in conjunction with the locking button 501.

[0063] In order to further improve the reliability and stability of the lawn mower body when people use the clamping frame 30 and the roller 40 to push the lawn mower body, the center of the roller 40 can also be connected to the hollow structure of the axle 304 through the plug-in 50. The hollow structure of the axle 304 is provided with a thread, and the plug-in 50 includes a locking button 501 with a thread and a clamping block 502 used in conjunction with the locking button 501.

[0064] The center of the roller 40 can be screwed into the hollow structure of the axle 304 through the threaded locking button 501. At this time, the roller 40 can be installed on the axle 304 of the clamping frame with the use of the clamping block 502, so that the roller 40 can automatically rotate on the axle 304 of the double fork arm. Fig.11 and Fig.12 , Fig.11 This is a schematic diagram of the roller being installed on the double wishbone axle through the locking button and the clamping block. Fig.12 It is a schematic diagram of the locking button being screwed out from the hollow structure of the double wishbone axle.

[0065] By adjusting the locking button 501 and the clamping block 502, the locking button 501 and the clamping block 502 can be moved back and forth along the axis of the wheel shaft 304. In practical applications, in order to ensure the tight fit between the locking button 501 and the clamping block 502, a gasket 503 can be added between the locking button 501 and the clamping block 502. It should be noted that in practical applications, the locking button 501 and the clamping block 502 with threads can also be replaced with a cam eccentric clamping structure, etc.

[0066] Obviously, through the technical solution provided in this embodiment, the roller can be detachably mounted on the axle of the clamping frame, and the roller can rotate freely on the axle of the clamping frame.

[0067] See also Fig.13 , Fig.13 This is a structural diagram of another intelligent lawn mower provided by an embodiment of the utility model. As a preferred embodiment, the intelligent lawn mower further includes: a mobile display terminal 60, which is wirelessly connected to the positioning navigation device 20 and the main controller 100 on the lawn mower body 10 through a communication module 120 provided on the lawn mower body 10.

[0068] In actual application, in order to further improve the convenience of people when using the smart lawn mower, a mobile display terminal 60 is also set in the smart lawn mower, wherein the mobile display terminal 60 can be wirelessly connected to the positioning navigation device 20 and the main controller 100 on the lawn mower body 10 through the communication module 120 set on the lawn mower body 10. The communication module 120 on the lawn mower body 10 can be a WiFi (wireless network communication technology) communication module, or a Bluetooth, ZigBee (a low-speed short-distance transmission wireless network protocol) module or a LoRa (Long Range Radio) module.

[0069] When the mobile display terminal 60 establishes a wireless connection with the main controller 100 and the positioning navigation device 20 on the lawn mower body 10 , the user can control the main controller 100 on the lawn mower body 10 by operating the mobile display terminal 60 , thereby achieving the purpose of controlling the lawn mower body 10 .

[0070] When the user controls the lawn mower body 10 to move through the mobile display terminal 60, the positioning navigation device 20 will record the movement trajectory of the lawn mower body 10. With this technical support, when the user needs to set the virtual boundary of the smart lawn mower, there is no need to install the clamping frame 30 and the roller 40 on the lawn mower body 10. The mobile display terminal 60 can be used to control the lawn mower body 10 to move within the specified area, so as to create the virtual boundary of the smart lawn mower. Fig.14 , Fig.14 This is a schematic diagram of a user controlling the lawn mower through a mobile display terminal to move in a specified area and create a virtual boundary. Fig.14 In the figure, 70 represents the virtual boundary created by the mobile display terminal 60 for the lawn mower body 10 .

[0071] When the user creates a virtual boundary of the smart lawn mower through the mobile display terminal 60, the virtual boundary can be stored in the smart lawn mower, so that the smart lawn mower can use the pre-created virtual boundary to control the lawn mower body 10 to perform mowing work within the virtual boundary in subsequent work.

[0072] Obviously, the technical solution provided by this embodiment can further improve people's user experience when using the smart lawn mower.

[0073] As a preferred implementation, the display screen of the mobile display terminal 60 is specifically a touch display screen.

[0074] Specifically, in actual application, the display screen of the mobile display terminal 60 can also be set as a touch screen. When the display screen of the mobile display terminal 60 is set as a touch screen, the user can control the smart lawn mower by touching the touch screen on the mobile display terminal 60 and control the walking track of the lawn mower body 10.

[0075] Obviously, the technical solution provided by this embodiment can not only improve the efficiency of the user in controlling the smart lawn mower, but also further improve the user experience of the user when using the smart lawn mower.

[0076] See also Figure 5 , Figure 5 This is a structural diagram of a clamping frame provided in an embodiment of the utility model. As a preferred embodiment, a clamp 305 for clamping the mobile display terminal 60 is provided on the telescopic rod 302 .

[0077] In order to enable the user to more intuitively and conveniently view the walking track of the smart lawn mower body 10 on the mobile display terminal 60 when using the smart lawn mower, a clamp 305 for clamping the mobile display terminal 60 may also be provided on the telescopic rod 302 of the clamping frame 30 .

[0078] In this configuration, the user can view the moving track of the lawn mower body 10 in real time through the mobile display terminal 60 clamped on the clamp 305 of the telescopic rod 302 while pushing the lawn mower body 10 to move using the clamping frame 30 and the roller 40 .

[0079] Obviously, the technical solution provided in this embodiment can further improve the user experience when people use the smart lawn mower.

[0080] Based on the above embodiments, this embodiment further illustrates and optimizes the technical solution. As a preferred implementation, the positioning navigation device 20 is specifically an RTK navigation device or a UWB navigation device or a visual navigation device.

[0081] It can be understood that RTK (Real Time Kinematic) navigation equipment refers to navigation equipment designed using RTK technology. Therefore, this type of navigation equipment not only has high positioning accuracy and no error accumulation, but also can automatically realize a variety of surveying and mapping functions without human intervention, thereby improving the convenience of people timing the lawn mower body 10 when using RTK navigation equipment.

[0082] UWB (Ultra Wide Band) navigation equipment refers to navigation equipment designed using UWB technology. Since UWB technology has the advantages of insensitivity to signal attenuation, low power spectrum density of transmitted signals and low interception rate, under this setting mechanism, UWB navigation equipment not only has higher positioning security, but also has lower power consumption.

[0083] Visual navigation devices can perceive the three-dimensional space environment through camera ranging technology, which makes them more resistant to interference and have more accurate positioning effects.

[0084] To sum up, since RTK navigation devices, UWB navigation devices and visual navigation devices all have high positioning accuracy, in actual applications, the positioning navigation device on the lawn mower body can be set to an RTK navigation device or a UWB navigation device or a visual navigation device, and the RTK navigation device, UWB navigation device or the visual navigation device set on the lawn mower body can be used to locate the walking trajectory of the lawn mower body.

[0085] Obviously, the technical solution provided by this embodiment can ensure diversity and flexibility in setting up positioning and navigation equipment.

[0086] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
