Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a lawn mowing device and a mobile device. Background Technology

[0002] With the popularization of intelligent mobile robot technology, mobile devices with path planning functions, such as lawnmower robots that automatically extend ropes to mow lawns, are gradually replacing traditional manual lawn maintenance. However, in existing technologies, the spool material is integrated into the mowing head, resulting in a large space occupation at the mowing head. This encroaches on the space for core components such as the cutting parts of the mowing head, reduces the lawn cutting range of the mowing head, and ultimately affects the mowing efficiency of the mobile device. Utility Model Content

[0003] This application provides a lawn mowing device and a mobile device. By removing the rope winding component from the lawn mowing device, it can be placed anywhere else on the mobile device, which helps to ensure that the lawn mowing device is compact and lightweight, and improves the lawn mowing efficiency of the mobile device.

[0004] In a first aspect, embodiments of this application propose a lawn mowing device, including a cutting component and a transmission component. The cutting component is used to drive the mowing rope to rotate in order to perform operations on the lawn. The transmission component is used to receive one end of the mowing rope and pull the mowing rope out from the rope winding member to deliver it into the cutting component. The transmission component is also used to make a portion of the mowing rope extend out of the cutting component. The mowing rope is wound around the periphery of the rope winding member.

[0005] This application improves the usability of the mowing device by removing the rope winding component from the mowing device and using a transmission component to transport the mowing rope into the cutting component and partially extend it out of the cutting component. This makes the mowing device more compact and lightweight, while the rope winding component has a larger capacity to reduce the frequency of replacing the mowing rope. Both of these improvements contribute to the ease of use of the mowing device.

[0006] In one possible implementation, the transmission assembly includes a first drive member and a winch. The output shaft of the first drive member is connected to the winch, and the winch is drive-connected to the mowing rope. The transmission assembly has a first channel, and the first drive member is used to drive the winch to rotate, thereby transmitting a portion of the mowing rope through the first channel into the cutting assembly. This allows the transmission assembly to efficiently drive the mowing rope via the winch and precisely transmit the mowing rope into the cutting assembly through the first channel, ultimately causing a portion of the mowing rope to extend outside the cutting assembly. This improves the mowing efficiency of the mowing device.

[0007] In one possible implementation, the axis of the output shaft of the first drive unit coincides with the axis of the winch, and the axis of the winch is perpendicular to the extension direction of the first channel. By aligning the axis of the output shaft of the first drive unit with the axis of the winch, the winch can rotate in place under the drive of the first drive unit without eccentric rotation, which is beneficial to improving the conveying efficiency of the mowing rope. By making the axis of the winch perpendicular to the extension direction of the first channel, the radial direction of the winch can be aligned with the extension direction of the first channel, that is, the winch can be set vertically relative to the first channel without tilting. The winch does not need to occupy additional space along the axis of the mowing device, which is beneficial to the miniaturization of the mowing device.

[0008] In one possible implementation, the cutting assembly includes a second drive member and a working head, with the output shaft of the second drive member connected to the working head. The working head has a second channel, and the first drive member drives a winch to rotate, sequentially transferring a portion of the hay trimming rope through the first and second channels to the outside of the working head. The working head acts as a medium, efficiently transferring the momentum output by the second drive member to the hay trimming rope, and also provides protection for the prepared hay trimming rope, preventing damage from the external environment to the rope located within the second channel, thus facilitating efficient and stable lawn trimming operations.

[0009] In one possible implementation, the output shaft of the second drive unit has a third channel, and the first, third, and second channels are sequentially connected along a direction perpendicular to the lawn to be mowed. This allows the mowing rope to be transmitted sequentially through the first, third, and second channels to the outside of the cutting assembly for operation, ensuring precise and efficient transmission of the mowing rope. Furthermore, the first, second, and third channels are coaxial, meaning the transmission assembly, the second drive unit, and the working head are sequentially arranged along a direction perpendicular to the lawn to be mowed, eliminating the need for misalignment and facilitating the miniaturization of the mowing device.

[0010] In one possible implementation, the mowing device further includes a motor bracket, the housing of which encloses a receiving cavity, within which a second drive component is located. The housing has a through hole through which a first channel and a third channel communicate. The motor bracket protects the second drive component from external environmental interference and prevents the third channel of the second drive component from being affected by external substances, thus ensuring the mowing efficiency of the device.

[0011] In one possible implementation, the mowing device further includes a cutting element disposed within the housing. The cutting element is used to cut the mowing rope that comes into contact with it. When the mowing rope extends too far beyond the cutting assembly, the cutting element can cut off the excess rope, thus preventing the effective working length of the rope from becoming too long, controlling the mowing width, and facilitating precise mowing of the lawn.

[0012] In one possible implementation, the transmission assembly further includes an encoder, which is located on the side of the first drive member opposite to the winch. The encoder detects the position of the rotor of the first drive member to control the length of the mowing rope extending beyond the cutting assembly. By detecting the position of the motor rotor of the first drive member through the encoder, the number of rotations of the motor rotor of the first drive member can be determined. Based on this, the final length of the mowing rope extending beyond the cutting assembly can be controlled, thereby controlling the mowing width and facilitating precise mowing of the lawn.

[0013] Secondly, embodiments of this application propose a mobile device, including a device body, a mowing rope, a rope winding component, and the mowing device described in the first aspect, wherein the rope winding component is disposed on the device body.

[0014] In this embodiment, by placing the rope winder on the main body of the device instead of the mowing device, the rope winder can be made larger, allowing for the winding of more mowing rope and reducing the frequency of rope replacements by the user. When a roll of mowing rope is used up, only a new roll needs to be replaced by hanging the rope winder on the main body of the device, which facilitates the convenient use of the mowing device.

[0015] In one possible implementation, the main body of the equipment includes a swing arm mechanism, with a rope winding component and a cutting component respectively disposed at opposite ends of the swing arm mechanism along the width direction of the main body. The swing arm mechanism can drive the mowing device to swing as it operates on irregular lawns, adapting to changes in terrain and improving the efficiency of the mobile equipment in lawn operations.

Detailed Implementation

[0022] For ease of understanding, the relevant technical terms involved in the embodiments of this application will be explained and described below.

[0023] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more.

[0024] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Features specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "side," "top," and "bottom," are only for reference to the directions in the accompanying drawings. These directional terms are used to better and more clearly explain and understand the embodiments of this application, and are not intended to explicitly or implicitly suggest that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, etc., and therefore should not be construed as limiting the embodiments of this application.

[0026] The development of automated mobile devices is rapid, and their application scenarios are expanding. With the popularization of intelligent mobile robot technology, mobile devices with path planning capabilities, such as lawnmower robots that automatically extend ropes to mow lawns, are gradually replacing traditional manual lawn maintenance. However, in existing technologies, the spool material is integrated into the mowing head, resulting in a large space occupation at the mowing head. This encroaches on the space available for core components such as the cutting parts, reducing the mowing head's cutting range. Furthermore, if the volume of the spool material is reduced to free up space for the mowing head, the spool capacity will be very small, leading to frequent material consumption and increased replacement frequency. All of these factors negatively impact the mowing efficiency of mobile devices.

[0027] This application provides a lawn mowing device and a mobile device. By removing the rope winding component from the lawn mowing device, it can be placed anywhere else on the mobile device, which makes the lawn mowing device compact and lightweight, and improves the lawn mowing efficiency of the mobile device.

[0028] Figure 1 This is a schematic diagram of the structure of the mobile device 1000 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the cooperative structure of the mowing device 1, the rope winding component 2, the mowing rope 3, and the swing arm mechanism 120 provided in the embodiments of this application. Figure 1 and Figure 2 As shown, the mobile device 1000 includes a main body 100, a mowing device 1, a rope winder 2, a trimming rope 3, and wheels 110. There are two wheels 110, positioned on opposite sides of the main body 100 along the width direction of the mobile device 1000, and these wheels drive the mobile device 1000. The rope winder 2 is located at the front end of the main body 100, along the direction of travel of the mobile device 1000. The wheels 110 and the rope winder 2 are sequentially positioned on the main body 100. The rope winder 2 can be positioned on one of the opposite sides of the main body 100 along the width direction of the mobile device 1000. The peripheral surface 21 of the rope winder 2 can be used to wind the trimming rope 3. The end of the trimming rope 3 away from the rope winder 2 passes through the mowing device 1 and is partially exposed outside the mowing device 1, meaning the portion of the trimming rope 3 extending from the mowing device 1 can trim the lawn under the drive of the mowing device 1. The grass-cutting device 1 is located on the main body 100 of the equipment, and the grass-cutting device 1 is separated from the rope winding component 2, which helps to ensure that the grass-cutting device 1 is compact and lightweight.

[0029] Combination Figure 1 and Figure 2As shown, the lawn mowing device 1 includes a cutting assembly 11 and a transmission assembly 12. The cutting assembly 11 drives the mowing rope 3 to rotate for lawn mowing. The transmission assembly 12 receives one end of the mowing rope 3, i.e., the end of the mowing rope 3 away from the transmission assembly 12 is disposed on the winding member 2, and the end of the mowing rope 3 away from the winding member 2 is received by the transmission assembly 12. The transmission assembly 12 is used to extract the mowing rope 3 from the winding member 2 and transport it into the cutting assembly 11. The transmission assembly 12 is also used to allow a portion of the mowing rope 3 to extend out of the cutting assembly 11. That is, the mowing rope 3 may include the following parts: a portion of the mowing rope 3 wound around the peripheral side 21 of the winding member 2; a portion of the mowing rope 3 located between the winding member 2 and the lawn mowing device 1; a portion of the mowing rope 3 located within the transmission assembly 12 and the cutting assembly 11; and a portion of the mowing rope 3 extending out of the lawn mowing device 1. In this embodiment, by removing the rope winding component 2 from the mowing device 1 and conveying the mowing rope 3 to the cutting component 11 via the transmission component 12 and partially extending it out of the cutting component 11, the mowing device 1 becomes more compact and lightweight. At the same time, the rope winding component 2 has a larger capacity to reduce the replacement frequency of the mowing rope 3. All of the above are beneficial to the convenient use of the mowing device 1.

[0030] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the equipment body 100 includes a swing arm mechanism 120. Along the width direction of the equipment body 100, the rope winding member 2 and the cutting assembly 11 are respectively disposed at opposite ends of the swing arm mechanism 120. Schematically, the swing arm mechanism 120 includes a first mounting portion 1201, a second mounting portion 1202, and an elastic member 1203. Along the width direction of the equipment body 100, the first mounting portion 1201, the second mounting portion 1202, and the elastic member 1203 are connected sequentially. The rope winding member 2 is disposed at the first mounting portion 1201, and the mowing device 1 is disposed at the second mounting portion 1202. The elastic member 1203 is used to swing when the mobile equipment 1000 is moving, which allows the swing arm mechanism 120 to drive the mowing device 1 to swing as it operates on irregular lawns, adapting to changes in terrain and improving the grass-cutting efficiency of the mobile equipment 1000.

[0031] Figure 3 This is a schematic diagram of the cooperative structure of the mowing device 1 and the mowing rope 3 provided in the embodiments of this application. Figure 4 This is a schematic diagram of the cooperative structure of the mowing device 1, the rope winding component 2, and the mowing rope 3 provided in the embodiments of this application. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in one possible implementation, the transmission assembly 12 includes a main body 121, a first drive member 122, and a winch 123. The main body 121 has a protective cavity, and the first drive member 122 is partially located within the protective cavity, as is the winch 123. The output shaft of the first drive member 122 is connected to the winch 123, which is drively connected to the mowing rope 3, meaning the winch 123 can transmit the output momentum of the first drive member 122 to the mowing rope 3. The transmission assembly 12 has a first channel 1211 located within the main body 121, and the extension direction of the first channel 1211 can be perpendicular to the direction of the lawn to be cut. The first drive member 122 can drive the winch 123 to rotate, thereby transmitting a portion of the mowing rope 3 through the first channel 1211 to the cutting assembly 11. The winch 123 can convert the rotational momentum of the first drive member 122 into the linear displacement of the mowing rope 3. Schematic, the transmission assembly 12 and the cutting assembly 11 are arranged sequentially along a direction perpendicular to the direction of the lawn to be cut. The cooperative structure of the first driving component 122, the winch 123 and the first channel 1211 enables the transmission component 12 to efficiently drive the mowing rope 3 through the winch 123 and accurately transmit the mowing rope 3 to the cutting component 11 through the first channel 1211, so that part of the mowing rope 3 extends out of the cutting component 11, which helps to improve the mowing efficiency of the mowing device 1.

[0032] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, the axis of the output shaft of the first drive member 122 coincides with the axis of the winch 123. Schematic, the axis of the output shaft of the first drive member 122 can be along the travel direction of the mobile device 1000. The axial direction of the winch 123 is perpendicular to the extension direction of the first channel 1211. By aligning the axis of the output shaft of the first drive member 122 with the axis of the winch 123, the winch 123 can rotate in place under the drive of the first drive member 122 without eccentric rotation, which is beneficial to improving the conveying efficiency of the straw rope 3. By making the axial direction of the winch 123 perpendicular to the extension direction of the first channel 1211, a radial direction of the winch 123 perpendicular to the direction of the lawn to be mowed can be aligned with the extension direction of the first channel 1211. Furthermore, the radial surface of the winch 123 is perpendicular to the width direction of the mobile device 1000, allowing the winch 123 to be set vertically relative to the first channel 1211 without tilting. The winch 123 does not require additional space along the axial direction of the mowing device 1, which is beneficial for the miniaturization of the mowing device 1.

[0033] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in one possible implementation, the cutting assembly 11 includes a second drive member 111 and a working head 112. The output shaft of the second drive member 111 is connected to the working head 112, and the second drive member 111 can drive the working head 112 to rotate. Specifically, the second drive member 111 is located between the working head 112 and the transmission assembly 12. The working head 112 has a second channel 1121, and the first drive member 122 is used to drive the winch 123 to rotate so as to transmit a portion of the mowing rope 3 sequentially through the first channel 1211 and the second channel 1121 to the outside of the working head 112. When the mowing device 1 performs weeding operations, the output shaft of the second drive member 111 drives the working head 112 to rotate. Since the mowing rope 3 located in the second channel 1121 is in contact with the inner wall of the working head 112, the mowing rope 3 can rotate with the working head 112 as the working head 112 rotates. That is, the working head 112 can act as a medium to efficiently transfer the momentum output by the second drive member 111 to the mowing rope 3. Furthermore, the working head 112 can provide protection for the prepared grass trimming rope 3, preventing damage to the grass trimming rope 3 located in the second channel 1121 from the external environment, which is conducive to the efficient and stable lawn trimming operation of the grass trimming rope 3.

[0034] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, the output shaft 1111 of the second drive member 111 has a third channel 11111, and the first channel 1211, the third channel 11111, and the second channel 1121 are sequentially connected along a direction perpendicular to the lawn to be cut. Specifically, along a direction perpendicular to the plane formed by the travel direction and width direction of the mobile device 1000, the transmission assembly 12, the second drive member 111, and the working head 112 are sequentially arranged. The first channel 1211, the third channel 11111, and the second channel 1121 can be used to form a vertical transmission channel, which extends from the side of the transmission assembly 12 adjacent to the rope winding member 2 to the side of the working head 112 adjacent to the lawn to be cut. This allows the cutting rope 3 to be smoothly transmitted to the outside of the cutting assembly 11 through the first channel 1211, the third channel 11111, and the second channel 1121 in sequence under the cooperative drive of the first drive member 122 and the winch 123, ensuring the precise and efficient transmission efficiency of the cutting rope 3. Furthermore, the first channel 1211, the second channel 1121, and the third channel 11111 are coaxial, meaning that the transmission assembly 12, the second drive component 111, and the working head 112 are arranged sequentially along a direction perpendicular to the lawn to be mowed. The transmission assembly 12, the second drive component 111, and the working head 112 do not need to be misaligned, which is conducive to the miniaturization of the mowing device 1 and further ensures that the mowing device 1 is compact and lightweight.

[0035] Combination Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, in one possible embodiment, the mowing device 1 further includes a motor bracket 13, which is located between the working head 112 and the transmission assembly 12. The motor bracket 13 includes a housing 131, the side of which away from the working head 112 is detachably connected to the main body 121 of the transmission assembly 12 via a threaded nut. The housing 131 forms a receiving cavity 132, and the second driving member 111 is located within the receiving cavity 132. The side of the housing 131 closest to the main body 121 has a through hole 1311, through which a first channel 1211 and a third channel 11111 communicate. That is, the mowing rope 3 can be driven by the first driving member 122 to sequentially pass through the first channel 1211, the through hole 1311, and the third channel 11111 into the second channel 1121 of the working head 112, and finally partially protrude from the working head 112. By setting a motor bracket 13 in the mowing device 1, the second drive component 111 can be protected from interference from the external environment, and the third channel 11111 of the second drive component 111 can be prevented from being invaded by external substances, thus affecting the delivery of the mowing rope 3, which is conducive to ensuring the mowing efficiency of the mowing device 1.

[0036] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one possible embodiment, the mowing device 1 further includes a cutting member 14, which is connected to the motor bracket 13. Specifically, the cutting member 14 is disposed in the housing 131 of the motor bracket 13. The length direction of the cutting member 14 may be perpendicular to the plane formed by the travel direction and width direction of the mobile device 1000. The end of the cutting member 14 away from the mowing rope 3 is connected to the housing 131 via a connector. The distance between the cutting member 14 and the rope outlet of the working head 112 is... Figure 4 As shown in the diagram, the maximum distance between the straw trimming rope 3 and the rope outlet of the working head 112 in the working state is... Figure 4 As shown in L2, the cutting element 14 can be used to cut the mowing rope 3 that is in contact with it. Specifically, when the length of the mowing rope 3 extending beyond the cutting assembly 11 is too long, the maximum distance L2 between the mowing rope 3 in the working state and the rope outlet of the working head 112 is greater than the distance L1 between the cutting element 14 and the rope outlet of the working head 112. The cutting element 14 contacts the mowing rope 3 in the working state, and the cutting element 14 can be used to cut off the excess mowing rope 3, so that the maximum distance L2 between the mowing rope 3 in the working state and the rope outlet of the working head 112 is reduced to less than or equal to the distance L1 between the cutting element 14 and the rope outlet of the working head 112. This avoids the effective working length of the mowing rope 3 being too long, controls the mowing width, and helps to achieve precise mowing of the lawn to be treated by the mowing device 1.

[0037] Combination Figure 1 , Figure 2, Figure 3 and Figure 4 As shown, in one possible implementation, the transmission assembly 12 further includes an encoder 124. The encoder 124 is disposed on the side of the first drive member 122 opposite to the winch 123. The encoder 124 is used to detect the position of the rotor of the first drive member 122 to control the length of the mowing rope 3 extending out of the cutting assembly 11. By detecting the position of the motor rotor of the first drive member 122 through the encoder 124, the number of rotations of the motor rotor of the first drive member 122 can be determined. Based on this, the final length of the mowing rope 3 extending out of the cutting assembly 11 can be controlled, thereby controlling the mowing width and facilitating precise mowing of the lawn by the mowing device 1.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
