Description

Technical Field

[0001] This utility model relates to the field of lawn mowing equipment technology, and in particular to lawn mowers. Background Technology

[0002] A lawnmower, also known as a lawn mower or lawn trimmer, is a mechanical tool used for trimming lawns, vegetation, etc. A lawnmower consists of a main body and a cutting mechanism, which is located below the main body, on the side facing the ground. Since grass in a lawn generally grows vertically upwards, the cutting mechanism cuts the vertically growing grass horizontally along the ground.

[0003] In related technologies, in order to avoid interference between the cutting area of ​​the cutting mechanism and the walking mechanism of the main body, the cutting area is usually smaller than the bottom surface of the main body. This makes it difficult for the cutting mechanism to cut to the edge of the lawn, so manual trimming of the lawn is required, which adds a lot of trouble to users and reduces the user experience.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 13 As shown in the figure, this utility model embodiment discloses a lawnmower, which includes a main body 100, an edge mowing mechanism 200, and a threaded connector 300.

[0022] The main body 100 provides a mounting base for other components of the lawnmower. The main body 100 includes, but is not limited to, the mounting housing, walking mechanism, circuit structure, control mechanism, and other devices. The main body 100 is the main structure of the lawnmower, used to realize functions such as walking, power supply, and control.

[0023] The edge trimming mechanism 200 includes a fixed base 210, a drive unit 220, and a trimming component 230. The fixed base 210 is fixed to the side of the main body 100. Here, the side can be understood as the outer peripheral surface of the main body 100. The drive unit 220 is located on the side of the fixed base 210 away from the main body 100. The drive unit 220 is connected to the trimming component 230 and is used to drive the trimming component 230 to rotate to form a trimming area.

[0024] During the specific weeding process, when the drive unit 220 drives the mowing component 230 to rotate, the mowing component 230 can form a mowing area, thereby cutting longer grass to achieve lawn mowing. At this time, as the main body 100 moves, the mowing area also moves, thus enabling the entire lawn to be mowed.

[0025] In the embodiments disclosed in this application, the edge trimming mechanism 200 is fixed on the side of the main body 100. At this time, the trimming area formed by the edge trimming mechanism 200 is located on one side of the main body 100. Therefore, the trimming area formed by the edge trimming mechanism 200 can cut to the edge of the lawn, thereby enabling lawn trimming and avoiding unnecessary trouble for users, thus improving the user experience.

[0026] In the above solution, the fixed base 210 can be locked to the main body 100 with bolts. However, during installation, the user needs to continuously support the edge trimming mechanism 200, align the bolts with the corresponding holes, and then tighten the bolts to lock them in place. This process requires continuously supporting the edge trimming mechanism 200, making the assembly of the main body 100 and the edge trimming mechanism 200 quite difficult.

[0027] In the embodiments disclosed in this application, one of the fixed base 210 and the side of the main body 100 is provided with a hook-on buckle 2101, and the other is provided with a hook-on hole 101. The hook-on buckle 2101 is engaged with the hook-on hole 101. The fixed base 210 has a connecting hole 2102, and the side of the main body 100 has a threaded hole 102. One end of the threaded connector 300 passes through the connecting hole 2102 and is threadedly connected to the threaded hole 102 to fix the fixed base 210 to the main body 100.

[0028] During the specific installation process, the edge trimming mechanism 200 is first attached to the side of the machine body 100 via the hook 2101 on the fixed base 210, and then the threaded connector 300 is inserted to lock and fix the edge trimming mechanism 200 to the machine body 100.

[0029] In the embodiments disclosed in this application, during the installation of the edge-cutting mechanism 200, the user can first hook the edge-cutting mechanism 200 onto the main body 100 using the hook-and-loop fastener 2101. This allows the edge-cutting mechanism 200 to be pre-installed onto the main body 100 and prevents it from falling off. Then, it is locked using the threaded connector 300 to complete the final installation. In this solution, when installing the edge-cutting mechanism 200, the user can hook it onto the main body 100 using the hook-and-loop fastener 2101, eliminating the need for the user to continuously support the edge-cutting mechanism 200 and reducing the installation difficulty between the edge-cutting mechanism 200 and the main body 100.

[0030] Optionally, the threaded connector 300 can be a bolt, screw, or other threaded connection structure, which is not limited in this article.

[0031] The aforementioned mowing component 230 may include a rotating head and a cutting section disposed on the rotating head. The rotating head may be connected to the drive unit 220, and the rotating head drives the cutting section to rotate to form a mowing area. The cutting section may be a flexible cable or a blade; the specific structure of the cutting section is not limited herein. The drive unit in this application may be a servo motor or a three-phase asynchronous motor; of course, the drive unit may also be other power structures, which are not limited herein.

[0032] In the embodiments disclosed in this application, the lawnmower may only be equipped with an edge trimming mechanism 200. In this case, the edge trimming mechanism 200 can perform lawn trimming operations and is used for large-area trimming operations.

[0033] Alternatively, in another alternative embodiment, the lawnmower may also include a main cutting mechanism mounted on the bottom surface of the main body 100. In this case, the main cutting mechanism is used for large-area mowing operations, while the edge trimming mechanism 200 can only perform edge trimming operations. Since the main cutting mechanism is mounted on the main body 100, it can be understood as part of the main body 100; therefore, the main body can perform large-area mowing, while the edge trimming mechanism 200 performs edge trimming operations. The specific structure of the main cutting mechanism is not limited herein.

[0034] In the above scheme, a boundary detection module can be installed on the main body 100. This module detects the boundary of the working area and outputs a boundary detection signal. The lawnmower, through the boundary detection module, detects the boundary of the working area and outputs a boundary detection signal. The control device of the main body 100 receives this signal, thus enabling the main body 100 to define the working area. The walking mechanism on the main body 100 can then drive the lawnmower to work within this area, where the boundary is the lawn boundary. The edge-trimming mechanism 200 can trim the lawn boundary.

[0035] In the above scheme, the edge trimming mechanism 200 and the main body 100 can be electrically connected by cables, thereby enabling the main body 100 to control and supply power to the edge trimming mechanism 200.

[0036] In another alternative embodiment, the lawnmower may further include a first electrical connector 400, which may be disposed on the side of the main body 100. The first electrical connector 400 may include a plurality of first electrical contacts 410, which are spaced apart and electrically connected to the main body 100. The electrical connection of the plurality of first electrical contacts 410 to the internal circuitry of the main body 100 is known technology and is not limited herein.

[0037] The edge trimming mechanism 200 may further include a second electrical connector 240. The second electrical connector 240 may be disposed on the side of the fixed base 210 facing the main body 100. The second electrical connector 240 may include a plurality of second electrical contacts 241, which are spaced apart and electrically connected to the drive unit 220. The plurality of second electrical contacts 241 and the drive unit 220 may be electrically connected via cables or flexible circuit boards, which are not limited herein. The first electrical contact 410 and the second electrical contact 420 mentioned above are both metal contacts, and electrical conduction can be achieved when the first electrical contact 410 and the second electrical contact 420 are in contact.

[0038] During the installation process, when the fixed base 210 is installed on the main body 100, the multiple first electrical contacts 410 and the multiple second electrical contacts 241 make contact and conduct electricity in a one-to-one correspondence.

[0039] In this design, the main body 100 and the edge-cutting mechanism 200 are electrically connected via electrical contacts. This contact connection method avoids excessively long cables, thus preventing the risk of cable tangling or breakage during operation and enhancing the safety and reliability of the lawnmower. Furthermore, when the fixed base 210 is installed on the main body 100, it completely covers the first electrical contact 410 and the second electrical contact 241, thereby preventing the first electrical contact 410 and the second electrical contact 241 from being exposed.

[0040] In the embodiments disclosed in this application, the corresponding electrical contacts can perform corresponding functions. For example, when the first electrical contact 410 on the main body 100 for power supply is connected to the second electrical contact 241 on the edge-cutting mechanism 200 for power supply, the main body 100 can supply power to the edge-cutting mechanism 200. As another example, when the first electrical contact 410 on the main body 100 for function control is connected to the second electrical contact 241 on the edge-cutting mechanism 200 for function control, the main body 100 can perform corresponding control on the edge-cutting mechanism 200.

[0041] In the above scheme, the first electrical contact 410 and the second electrical contact 241 can be magnetically attached, and the first electrical contact 410 and the second electrical contact 241 can be magnetically engaged. Alternatively, the first electrical connector 400 can include a first mounting plate, with multiple first electrical contacts 410 spaced apart on the first mounting plate, and the first mounting plate is mounted to the main body of the device. The second electrical connector 240 can include a second mounting plate, with multiple second electrical contacts 241 spaced apart on the second mounting plate, and the second mounting plate is mounted to the fixed base 210. In this case, the first mounting plate and the second mounting plate can be magnetically attached, and the first mounting plate and the second mounting plate can be magnetically engaged.

[0042] In the above scheme, the mowing area is roughly parallel to the lawn surface. This can be understood as the mowing area being parallel to the horizontal plane. However, at the lawn's boundaries, the grass not only grows vertically but also extends horizontally outwards. Since some grass extends beyond the boundaries and is closer to the ground, its height may be lower. Therefore, when the lawnmower cuts the lawn horizontally, the grass growing vertically at the boundaries is cut, but the horizontally extending grass cannot be effectively trimmed. This results in the lawn boundaries becoming uneven and messy due to the different growth trends of the grass, thus reducing the user experience.

[0043] In another alternative embodiment, the drive unit 220 may include a first drive member 221, a second drive member 222, and a rotating shaft 223. The first drive member 221 can be rotatably connected to the fixed base 210 via the rotating shaft 223. The first drive member 221 can be connected to the mowing member 230 and can be used to drive the mowing member 230 to rotate. The second drive member 222 can be disposed on the fixed base 210 and can be connected to the rotating shaft 223. The second drive member 222 can drive the first drive member 221 to rotate relative to the fixed base 210 via the rotating shaft 223.

[0044] In specific operation, the second driving component 222 can drive the first driving component 221 to rotate, and the first driving component 221 simultaneously drives the mowing component 230 to rotate, thus changing the angle between the mowing area formed by the mowing component 230 and the ground. For example, Figure 2 As shown, when the edge-trimming mechanism 200 is in the first trimming position, the trimming area formed by the trimming component 230 is approximately parallel to the ground. At this time, the trimming area formed by the trimming component 230 is a horizontal plane. Figure 3 As shown, the second driving member 222 can drive the first driving member 221 to rotate 90°, so that the edge mowing mechanism 200 switches to the second mowing position. At this time, the mowing area formed by the mowing member 230 is approximately perpendicular to the ground. Therefore, the edge mowing mechanism 200 can trim grass growing horizontally along the roadside.

[0045] In this scheme, by rotating the first driving component 221, the angle between the mowing area and the ground can be adjusted, thereby mowing grass in multiple growth directions, making the lawn mowing more beautiful and neat.

[0046] In one alternative embodiment, the first driving component 221 may include a first driving motor 2211, a motor housing 2212, and a protective cover 2213. The motor housing 2212 may have a first through hole 2212a communicating with its inner cavity. The protective cover 2213 may be fixed to the outer surface of the motor housing 2212. The protective cover 2213 may have a second through hole 2213a, and the first through hole 2212a may communicate with the second through hole 2213a.

[0047] The first drive motor 2211 can be located in the inner cavity of the motor housing 2212, and the grass trimmer 230 can be located on the side of the protective cover 2213 away from the motor housing 2212. The output shaft of the first drive motor 2211 can pass through the first through hole 2212a and the second through hole 2213a in sequence and be connected to the grass trimmer 230. The motor housing 2212 can be rotatably connected to the fixed base 210 through the rotating shaft 223.

[0048] In this design, the first drive motor 2211 is located inside the motor housing 2212, thus protecting the first drive motor 2211. Simultaneously, the protective cover 2213 protects the mowing component 230, preventing damage to the mowing component 230 from stones at the lawn boundary. Therefore, this design further improves the safety performance of the edge mowing mechanism 200.

[0049] Optionally, the rotating shaft 223 may penetrate the motor housing 2212, or the rotating shaft 223 may include a first rotating shaft and a second rotating shaft, which may be located on opposite sides of the motor housing 2212. The protective cover 2213 may be a disc-shaped structure, or it may be as follows: Figure 12 The specific structure of the protective cover 2213 shown in the figure is not limited in this article.

[0050] In another alternative embodiment, the second driving component 222 may include a second driving motor 2221, a first gear 2222, and a second gear 2223. The second driving motor 2221 may be mounted on the fixed base 210. The first gear 2222 may be mounted on the output shaft of the second driving motor 2221. The second gear 2223 may be mounted on the rotating shaft 223. The first gear 2222 may mesh with the second gear 2223. The second driving motor 2221 may drive the rotating shaft 223 to rotate through the first gear 2222 and the second gear 2223, thereby driving the first driving component 221 to rotate.

[0051] In this scheme, the second drive component 222 has a simple structure, which simplifies the composition and cost of the edge trimming mechanism 200.

[0052] In an optional embodiment, the fixing base 210 may include a frame body 211, a first cover plate 212, a second cover plate 213, a first partition plate 214, and a second partition plate 215. The connecting hole 2102 and the hook buckle 2101 may both be provided on the frame body 211. A receiving groove may be opened on the side of the frame body 211 away from the body body 100. The first partition plate 214 and the second partition plate 215 are arranged in the receiving groove along the length direction of the frame body 211, and the receiving groove is divided into a first groove, a second groove 211c, and a third groove. The first cover plate 212 blocks the opening of the first groove to form a first mounting cavity 211a. The second groove 211c seals the opening of the third groove to form the second mounting cavity 211b. A portion of the first driving member 221 is located in the second groove 211c. At least one of the first partition plate 214 and the second partition plate 215 has a mounting hole 216. The rotating shaft 223 is mounted in the mounting hole 216. At least one of the first mounting cavity 211a and the second mounting cavity 211b may be provided with the second driving member 222.

[0053] In this design, a portion of the first driving member 221 is located within the second groove 211c, which helps reduce the size of the edge-trimming mechanism 200, thereby facilitating its miniaturization. Furthermore, the location of a portion of the first driving member 221 within the second groove 211c also provides better protection for the first driving member 221, improving its safety.

[0054] In the above scheme, part of the first driving member 221 is located in the second groove 211c, which restricts the rotation angle of the first driving mechanism and affects the mowing of the lawn.

[0055] Based on this, in another alternative solution, the side wall of the frame body 211 is provided with a clearance notch 211d that penetrates the edge of the groove 211c, and the clearance notch 211d is connected to the second groove 211c. In this solution, when the first driving member 221 rotates, the first driving member 221 can pass through the clearance notch 211d, thereby increasing the rotation angle of the first driving member 221.

[0056] Further, the frame body 211 may include a base plate 2111, a first substrate 2112, a second substrate 2113, a third substrate 2114, and a fourth substrate 2115. The first substrate 2112, the second substrate 2113, the third substrate 2114, and the fourth substrate 2115 are connected end to end along the circumference of the base plate 2111 to form a receiving groove. Here, the first substrate 2112, the second substrate 2113, the third substrate 2114, and the fourth substrate 2115 form the circumferential sidewalls of the frame body 211. The first substrate 2112 and the third substrate 2114 are arranged opposite each other, and the second substrate 2113 and the fourth substrate 2115 are arranged opposite each other. The second substrate 2113 and the fourth substrate 2115 are arranged along the length of the frame body 211. The first substrate 2112 and the third substrate 2114 are both provided with clearance notches 211d.

[0057] This design further increases the rotation angle of the first drive component 221, thereby further increasing the trimming angle of the edge trimming mechanism 200.

[0058] In one embodiment, the first cover plate 212 may have a first heat dissipation hole 212a, which may be connected to the first mounting cavity 211a. This embodiment can improve the heat dissipation performance of the edge-trimming grass mechanism 200.

[0059] Similarly, the second cover plate 213 can have a second heat dissipation hole 213a, which is connected to the second mounting cavity 211b. This design can also improve the heat dissipation performance of the edge-trimming mechanism 200.

[0060] In the above embodiments, a partial or complete area of ​​the first cover plate 212 may be provided with a louvered structure, and the aforementioned first heat dissipation hole 212a is formed between two adjacent louvers. Similarly, a partial or complete area of ​​the second cover plate 213 may be provided with a louvered structure, and the aforementioned second heat dissipation hole 213a is formed between two adjacent louvers. Of course, the heat dissipation holes on the first cover plate 212 and the second cover plate 213 may also be formed by a stamping process.

[0061] In one alternative embodiment, the first cover plate 212 may include a first plate body 2121 and a second plate body 2122 connected together. A first partition plate 214 may be connected to the end of the second plate body 2122 facing away from the first plate body 2121. The first plate body 2121 may be disposed opposite to the first partition plate 214, and the first plate body 2121 may be inclined relative to the second plate body 2122 in the direction facing away from the first partition plate 214. The first plate body 2121 may have a first heat dissipation hole 212a.

[0062] In this design, the first plate 2121 is inclined relative to the second plate 2122 in the direction away from the first partition plate 214, which makes it easier for external cold air to enter the first mounting cavity 211a, thus improving the heat exchange performance of the first mounting cavity 211a.

[0063] Similarly, the second cover plate 213 may include a third plate 2131 and a fourth plate 2132 connected together. A second partition plate 215 may be connected to the end of the third plate 2131 facing away from the fourth plate 2132. The fourth plate 2132 may be disposed opposite to the second partition plate 215, and the fourth plate 2132 may be inclined relative to the third plate 2131 in the direction away from the second partition plate 215. The fourth plate 2132 is provided with a second heat dissipation hole 213a.

[0064] In this design, the fourth plate 2132 is inclined relative to the third plate 2131 in the direction away from the second partition plate 215, which makes it easier for external cold air to enter the second mounting cavity 211b, thus improving the heat exchange performance of the second mounting cavity 211b.

[0065] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0066] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
