Detailed Implementation

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0058] This application provides a magnetic suction component and a lawnmower that can automatically collect metal fragments such as blades and screws that fall from the lawnmower, preventing such fragments from being left in the lawn and causing injury to pedestrians or children playing, thus eliminating safety hazards.

[0059] refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the lawnmower according to an embodiment of this application. Figure 2 This is a schematic diagram of the lawnmower rotating 180 degrees according to an embodiment of this application. Figure 3 for Figure 2 The diagram shows the disassembled structure of the lawnmower with its magnetic suction component. Figure 4 This is a schematic diagram of the lawnmower rotating 90 degrees according to an embodiment of this application. Figure 5 for Figure 4 The diagram shows the structure of the lawnmower with the magnetic suction component disassembled.

[0060] The lawnmower 100 can go along Figure 1 The lawnmower 100 travels in the direction shown (v) and cuts weeds and other vegetation along its path. The lawnmower 100 includes a vehicle body 10, a cutting assembly 20, and a magnetic attachment assembly 30. The cutting assembly 20 is mounted on the bottom of the vehicle body 10, and the magnetic attachment assembly 30 is detachably mounted on the bottom of the vehicle body 10. The vehicle body 10 can travel along... Figure 1The vehicle 10 travels in the direction v shown. During the movement of the vehicle body 10, the cutting assembly 20 cuts weeds and other plants along the path. In some embodiments, the magnetic suction assembly 30 is positioned behind the cutting assembly 20 along the travel direction v of the vehicle body 10.

[0061] In practical applications, the cutting assembly 20 includes metal components. For example, in some embodiments, the cutting assembly 20 includes a blade disc and blades disposed around the periphery of the blade disc, which cut plants by high-speed rotation of the blades. During the operation of the lawnmower 100, the blades may collide with hard objects such as stones or metal on the ground, causing the blades to break and fall onto the lawn. In addition, the lawnmower 100 also includes metal components such as screws. For example, blades are usually detachably mounted on the blade disc by screws. During the operation of the lawnmower 100, the screws may gradually loosen and fall off, and the loose screws will also fall onto the lawn.

[0062] The magnetic attraction component 30 can attract metal objects, such as blades and screws that have fallen onto the lawn, using magnetic force. It collects these attracted metal objects, preventing them from being left on the lawn and causing injury to pedestrians or children, thus eliminating safety hazards. Therefore, the magnetic attraction component 30 is positioned behind the cutting component 20 along the travel direction v of the vehicle body 10, allowing it to better attract metal objects that have fallen onto the lawn during the lawnmower 100's operation.

[0063] In some embodiments, the magnetic assembly 30 includes a magnetic element 31 and a collection box 32. The magnetic element 31 can be fixedly or detachably installed on the lawnmower 100, for example, on the bottom of the vehicle body 10. The collection box 32 is detachably installed on the lawnmower 100, for example, on the bottom of the vehicle body 10. The collection box 32 is positioned below the magnetic element 31 along the height direction of the lawnmower 100. The height direction of the lawnmower 100 can be understood as the direction perpendicular to the working surface (i.e., the plane where the lawn is located) when the lawnmower is in operation. For example, when the lawnmower 100 is operating on a horizontal lawn, the height direction is the vertical direction. The magnetic element 31 can attract metal objects, such as blades, screws, and other metal objects that have fallen onto the lawn, by magnetic force, and keep the metal objects in the collection box 32, thereby eliminating safety hazards.

[0064] In some embodiments, the magnetic attractor 31 includes one or more magnets. For example, in some embodiments, the magnetic attractor 31 includes a single magnet, which may be a permanent magnet or an electromagnet. In other embodiments, the magnetic attractor 31 includes an array of multiple magnets, all of which are permanent magnets or all of which are electromagnets, or at least one magnet is a permanent magnet and at least another magnet is an electromagnet.

[0065] In some embodiments, reference Figure 2 and Figure 3 When installing the magnetic suction assembly 30, the lawnmower 100 can be rotated 180 degrees so that its bottom faces upward. First, the magnetic suction component 31 is installed on the bottom of the lawnmower. Then, the collection box 32 is inserted horizontally into the bottom of the lawnmower, with the collection box 32 positioned above the magnetic suction component 31. When the lawnmower is rotated to a suitable working position (i.e., with the bottom of the lawnmower facing the ground), the collection box 32 is positioned below the magnetic suction component 31. Correspondingly, when disassembling the magnetic suction assembly 30, the collection box 32 can be removed first, followed by the magnetic suction component 31, or the magnetic suction component 31 can be left intact.

[0066] In some embodiments, reference Figure 4 and Figure 5 When installing the magnetic suction assembly 30, the lawnmower 100 can be rotated 90 degrees so that the front of the lawnmower 100 faces upwards in the direction of travel. First, the magnetic suction component 31 is inserted vertically into the bottom of the lawnmower, with the collection box 32 located to one side of the magnetic suction component 31. When the lawnmower is rotated to a suitable working position (i.e., the bottom of the lawnmower faces the ground), the collection box 32 is located below the magnetic suction component 31. Correspondingly, when disassembling the magnetic suction assembly 30, the collection box 32 can be removed first, followed by the magnetic suction component 31, or the magnetic suction component 31 can be left intact.

[0067] In some embodiments, reference Figure 6 , Figure 6 This is a schematic diagram of the vehicle body 10 of the lawnmower according to an embodiment of this application.

[0068] The bottom of the vehicle body 10 is provided with a mounting groove 11. The mounting groove 11 is used to install the magnetic suction assembly 30. In practical applications, to facilitate the installation of the magnetic suction assembly 30, the mounting groove 11 can be set as square or rectangular. The mounting groove 11 has a bottom wall 111 and a side wall 112, with the side wall 112 connected to the bottom wall 111. The side wall 112 forms an opening that faces downwards along the height direction of the lawnmower 100, i.e., the opening faces the ground. It should be noted that... Figure 6 The diagram shown is a structural schematic of the vehicle body 10 flipped 180 degrees. Therefore, in Figure 6 In the schematic diagram shown, the opening of the side wall 112 faces upward.

[0069] In some embodiments, the magnetic suction member 31 is fixedly or detachably mounted to the bottom wall 111, and the collection box 32 is detachably mounted to the side wall 112. For example, the magnetic suction member 31 can be fixed to the bottom wall 111 by adhesive. Alternatively, a non-metallic mounting shell can be provided outside the magnetic suction member 31, and the mounting shell can be detachably mounted to the bottom wall 111 by screws, so that the magnetic suction member 31 is detachably mounted to the bottom wall 111. The collection box 32 can be detachably mounted to the side wall 112 by means such as snap-fit.

[0070] In some embodiments, the magnetic member 31 can be fixed to the collection box 32, which is detachably mounted to the side wall 112. For example, the magnetic member 31 can be fixed to the collection box 32 by adhesive, and the collection box 32 can be detachably mounted to the side wall 112 by means such as snap-fit.

[0071] Continue to refer to Figure 6 In some embodiments, the sidewall 112 is provided with a notch 1121. For example, the sidewall 112 may be three-sided enclosed to form the notch 1121. The notch 1121 is used for mounting the collection box 32 to the sidewall 112 or removing it from the sidewall 112. For example, the collection box 32 can be inserted into the mounting slot 11 through the notch 112 or removed from the mounting slot 11.

[0072] In some embodiments, the sidewall 112 is provided with at least one second mounting portion 1122, which is used to cooperate with the collection box 32 to mount the collection box 32 in the mounting groove 11. The second mounting portion 1122 can be a slide or a slider.

[0073] In some embodiments, reference Figures 7 to 9 , Figure 7 This is a schematic diagram of the first structure of the collection box 32 of the magnetic suction assembly according to an embodiment of this application. Figure 8 for Figure 7 The front view of the collection box 32 shown. Figure 9 for Figure 8 The cross-sectional view of the collection box 32 shown along the P1-P1 direction.

[0074] The collection box 32 includes a base plate 321 and a side plate 322. The side plate 322 is connected to the periphery of the base plate 321 on the side opposite to the magnetic attractor 31. The side plate 322 is enclosed. The side plate 322 and the base plate 321 together form a receiving space 320, which is used to hold metal objects attracted by the magnetic attractor 31. It can be understood that since the collection box 32 is located below the magnetic attractor 31, and the side plate 322 is connected to the side of the base plate 321 opposite to the magnetic attractor 31, the receiving space 320 faces the ground during the operation of the lawnmower 100. After the magnetic attractor 31 attracts a metal object, the metal object can remain in the receiving space 320.

[0075] In some embodiments, the side panel 322 is provided with at least one first mounting portion 323. The first mounting portion 323 is used to detachably mount the collection box 32 to the lawnmower 100. The first mounting portion 323 is a slider or a groove. The first mounting portion 323 is used to cooperate with the second mounting portion 1122 of the vehicle body 10 to detachably mount the collection box 32 to the lawnmower 100 or remove it from the lawnmower 100. In some embodiments, the first mounting portion 323 is a slider, such as... Figure 7 As shown, the second mounting part 1122 is a sliding groove, such as Figure 6 As shown. In other embodiments, the first mounting portion 323 may also be a groove, and the second mounting portion 1122 may be a slider.

[0076] In some embodiments, the side panel 322 is provided with two first mounting portions 323, such as... Figure 8 As shown, two first mounting portions 323 are symmetrically arranged at opposite ends of the side plate 322. It can be understood that the symmetrical arrangement of the two first mounting portions 323 makes the collection box 32 easier to install and remove.

[0077] In practical applications, the number of second mounting parts 1122 is equal to the number of first mounting parts 323. For example, there are two first mounting parts 323 and two second mounting parts 1122. Each second mounting part 1122 is opposite to one first mounting part 323. The second mounting parts 1122 cooperate with the first mounting parts 323 so that the collection box 32 can be detachably mounted on the side wall 112 of the vehicle body 10.

[0078] Please refer to the above. Figures 6 to 9 Taking the first mounting part 323 as a slider and the second mounting part 1122 as a groove as an example, the installation and disassembly of the magnetic suction assembly 30 will be explained. When installing the magnetic suction assembly 30, the vehicle body 10 can be rotated 180 degrees first, so that the vehicle body 10 is in a position where... Figure 6 The vehicle body 10 is positioned with its bottom facing upwards. The magnetic chuck 31 is then fixed to the bottom of the mounting slot 11, for example, by using a mounting housing and screws to fix the magnetic chuck 31 to the bottom wall 111 of the mounting slot 11. The collection box 32 is then inserted laterally through the notch 1121 on the side wall 112 of the mounting slot, allowing the slider 323 to slide along the groove 1122 until the collection box 32 is installed in the mounting slot 11. In practical applications, the slider 323 and the groove 1122 can be press-fitted, causing the side wall 112 to hold the collection box 32 in place, preventing the collection box 32 from falling out of the mounting slot 11 after the vehicle body 10 is reset (i.e., the vehicle body returns to its working state). After the vehicle body 10 is reset, during the movement of the vehicle body 10, metal objects below the vehicle body 10 can be attracted to the collection box 32 by the magnetic chuck 31 and remain in the collection box 32. When disassembling the magnetic chuck assembly 30, the vehicle body 10 is similarly rotated 180 degrees so that the vehicle body 10 is in a neutral position. Figure 6 In the indicated state, with the bottom of the vehicle body 10 facing upwards, the collection box 32 is pulled laterally out of the mounting slot 11 through the notch 1121. Metal objects attracted by the magnetic 31 move away from the magnetic 31 and lose their magnetic attraction, then are held within the collection box 32 by the obstruction of the side plate 322. The magnetic 31 can be removed from the bottom of the mounting slot 11, or it can remain in place.

[0079] In some embodiments, reference Figures 10 to 12 , Figure 10 This is a schematic diagram of a second structure of the collection box 32 of the magnetic suction assembly according to an embodiment of this application. Figure 11 for Figure 10 The front view of the collection box 32 shown. Figure 12 for Figure 11 The shown is a cross-sectional view of the collection box 32 along the P2-P2 direction. The following is a description of... Figures 10 to 12 The collection box shown is Figures 7 to 9 The differences between the collection boxes shown will be explained, while the similarities can be found in the descriptions of the above embodiments, and will not be repeated here.

[0080] The collection box 32 also includes a top plate 324. The top plate 324 is opposite to the bottom plate 321 and is connected to the side plate 322. The area of ​​the top plate 324 is smaller than that of the bottom plate 321, and the top plate 324 can cover a portion of the accommodating space 320 while exposing another portion of the accommodating space 320. In some embodiments, the bottom plate 321, the side plate 322, and the top plate 324 are integrally formed, for example, by injection molding.

[0081] The accommodating space 320 includes a first collection area 320a and a second collection area 320b, which are connected. The first collection area 320a is not obstructed by the top plate 324, while the second collection area 320b is obstructed by the top plate 324. The first collection area 320a faces the ground, and the magnetic suction member 31 is directly opposite it. When the lawnmower 100 is in operation, the first collection area 320a faces the ground, and the magnetic suction member 31 is directly opposite and above the first collection area 320a, thus allowing metal objects attracted by the magnetic suction member 31 to remain within the first collection area 320a.

[0082] In some embodiments, such as Figure 10 As shown, the collection box 32 can be detached relative to the lawnmower 100 along direction s, which is perpendicular to the height direction of the lawnmower 100. Along the detachment direction s, the first collection area 320a is located at the front end, and the second collection area 320b is located at the rear end. That is, during the process of detaching the collection box 32 from the vehicle body 10, the first collection area 320a detaches from the mounting slot 11 first, and the second collection area 320b detaches from the mounting slot 11 afterward. Therefore, when the collection box 32 is detached from the lawnmower 100, the metal object remaining in the accommodating space 320 moves from the first collection area 320a to the second collection area 320b under the magnetic attraction of the magnetic suction member 31. Due to the obstruction of the side plate 322 and the top plate 324, the metal object can be retained within the collection box 32.

[0083] Please refer to the above. Figure 4 , Figure 5 as well as Figures 10 to 12Taking the first mounting part 323 as a slider and the second mounting part 1122 as a groove as an example, the installation and disassembly of the magnetic suction assembly 30 will be explained. When installing the magnetic suction assembly 30, the vehicle body 10 can be rotated 90 degrees first, so that the vehicle body 10 is in a position... Figure 5 The vehicle body 10 is positioned with its front facing upwards along the direction of travel. The magnetic chuck 31 is then fixed to the bottom of the mounting slot 11, for example, by using a mounting housing and screws to fix the magnetic chuck 31 to the bottom wall 111 of the mounting slot 11. The collection box 32 is then vertically inserted downwards through the notch 1121 on the side wall 112 of the mounting slot. During insertion, the second collection area 320b is positioned below, and the first collection area 320a is positioned above, causing the slider 323 to slide along the groove 1122 until the collection box 32 is installed in the mounting slot 11. It should be noted that in this embodiment, the vehicle body 10 is in a... Figure 5 In the indicated state, the notch 1121 of the side wall 112 of the mounting slot faces upward. In practical applications, the slider 323 and the groove 1122 can be pressurized to lock the collection box 32, preventing the collection box 32 from falling out of the mounting slot 11 after the vehicle body 10 is reset (i.e., the vehicle body returns to the working state). After the vehicle body 10 is reset, during the movement of the vehicle body 10, metal objects under the vehicle body 10 can be attracted to the collection box 32 by the magnetic suction component 31 and left in the first collection area 320a. When disassembling the magnetic suction component 30, the vehicle body 10 is similarly rotated 90 degrees first, so that the vehicle body 10 is in the position of Figure 5 As shown, the collection box 32 is then pulled vertically upward out of the mounting slot 11 through the notch 1121. After the metal object attracted by the magnetic 31 moves away from the magnetic 31 and loses its magnetic attraction, it is blocked by the side plate 322 and the top plate 324 of the collection box 32 and moves from the first collection area 320a to the second collection area 320b, and remains in the second collection area 320b.

[0084] In some embodiments, reference Figure 13 , Figure 13 This is a schematic diagram of a third structure of the collection box 32 of the magnetic suction assembly according to an embodiment of this application. The following is a description of... Figure 13 The differences between the collection box shown and the collection box in the above embodiment will be explained. The similarities can be found in the description in the above embodiment, and will not be repeated here.

[0085] The side panel 322 of the collection box 32 has a notch 3221. Compared to the side panel 322 being enclosed, setting the side panel 322 with a notch 3221 makes it easier to clean the metal objects left inside the collection box 32. For example, the metal objects can be poured out through the notch 3221.

[0086] In some embodiments, reference Figure 14 , Figure 14 This is a schematic diagram of a fourth structure of the collection box 32 of the magnetic suction assembly according to an embodiment of this application. The following describes... Figure 14 The differences between the collection box shown and the collection box in the above embodiment will be explained. The similarities can be found in the description in the above embodiment, and will not be repeated here.

[0087] The collection box 32 is slidably connected to the side wall 112 of the vehicle body 10. The collection box 32 can slide relative to the side wall 112 along the height direction of the lawnmower 100, meaning it can slide up and down. Understandably, in practical applications, the working surface (i.e., the lawn surface) of the lawnmower 100 is not always flat and may contain obstacles such as stones. By configuring the collection box 32 to slide up and down, when encountering obstacles such as stones, the bottom of the collection box 32 can be pushed up and slide upwards when squeezed by the obstacle, allowing the collection box 32 to adapt to different terrains.

[0088] In some embodiments, such as Figure 14 As shown, at least one end of the side plate 322 of the collection box 32 is provided with a first slider 323a and a second slider 323b. The first slider 323a and the second slider 323b are spaced apart along the height direction of the lawnmower 100, for example, the first slider 323a is located above and the second slider 323b is located below. At least one of the first slider 323a and the second slider 323b is slidably connected to the side plate 322. That is, at least one of the first slider 323a and the second slider 323b can slide relative to the side plate 322, for example, relative to the side plate 322 along the height direction of the lawnmower 100. An elastic member 325 is provided between the first slider 323a and the second slider 323b. The elastic member 325 can be, for example, a spring. The elastic member 325 can be compressed or extended to allow the collection box 32 to slide relative to the side wall 112 of the vehicle body 10. In practical applications, when the collection box 32 is squeezed by an obstacle, it is pushed upwards, and the elastic element 325 is compressed, causing the collection box 32 to slide upwards relative to the side wall 112. When the collection box 32 is no longer squeezed by an obstacle, the elastic element 325 automatically extends due to its elastic restoring force, pushing the collection box 32 downwards, causing it to slide downwards relative to the side wall 112. Therefore, the collection box 32 can slide up and down, improving its adaptability to different terrains.

[0089] In some embodiments, the magnetic connector 31 can be fixed to the bottom of the collection box 32 and detachably installed on the vehicle body 10 together with the collection box 32. During installation, the vehicle body 10 does not need to be flipped; the collection box 32 and the magnetic connector 31 can be directly inserted into the mounting slot 11 of the vehicle body 10. During disassembly, the collection box 32 and the magnetic connector 31 are pulled out of the mounting slot 11 together, then the collection box 32 is flipped so that the magnetic connector 31 is at the bottom, and then the magnetic connector 31 is removed to take out the metal object inside the collection box 32.

[0090] In some embodiments, the collection box 32 may also be fixed in the mounting slot 11 by means of snaps, screws or the like, rather than by sliding and snapping.

[0091] In some embodiments, a metal detection sensor may be installed inside the vehicle body 10, positioned near the collection box 32, to detect whether there is a metal object inside the collection box 32. When a metal object is detected inside the collection box 32, an alarm signal can be issued to prompt the user to clean it.

[0092] In the description of this application, it should be understood that terms such as “first” and “second” are used only to distinguish similar objects and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
