[0039] like Figures 1 to 9 As shown in the embodiment of this application, a mowing structure 11 is disclosed, comprising:
[0040] Connector 1 includes a first connecting end 101 and a second connecting end 102;
[0041] The base 2 is embedded in the connector 1, and the base 2 includes a first connection port 201 and a second connection port 202;
[0042] The active block 3 is connected to the first connection end 101 through the first connection port 201;
[0043] The counterweight 4 is connected to the second connection end 102 through the second connection port 202;
[0044] The lower cover plate 5 is placed on the base 2.
[0045] The connector 1 can be provided with a first connecting end 101, a second connecting end 102, and a motor drive connecting end. The first connecting end 101 and the second connecting end 102 can be cylindrical at the end near the top surface of the base 2. The motor drive connecting end is connected to the drive shaft of the mowing motor, and can drive the rotation of the entire mowing module, including the rotation of the base 2, under the drive of the drive shaft. In addition, the connector 1 can be made of a material with sufficient strength, such as metal, so that the risk of breakage between the motor drive shaft and the mowing module can be avoided during the operation of the mowing structure 11. The base 2 can include a connecting shaft 204 passing through the base 2 and a rope outlet 203. The connecting shaft 204 of the base 2 is sleeved on the central shaft of the winding component 6. The movable block 3 is movably connected to the connecting shaft 204. The rope outlet 203 is used to extend the mowing rope 7 in the winding component 6. In addition, the overall shape of the base 2 can also be set according to the requirements, such as setting it to a shape that is easy to injection mold. One end of the movable block 3 can be connected to the connecting shaft 204. The first connecting port 201 in the base 2 is movably connected to the first connecting end 101 of the connector 1, and the other end of the movable block 3 can abut against the first movable groove 601 of the winding component 6. When the movable block 3 is in the movable state, it can move within the space restricted by the first movable groove 601. One end of the counterweight block 4 can be movably connected to the second connecting end 102 of the connector 1 through the second connecting port 202 in the base 2, and the other end of the counterweight block 4 can be connected to the first movable groove 601 of the winding component 6. It can be a block structure with a certain weight. The setting of this structure can ensure that the grass trimming rope 7 in the grass trimming module plays a dynamic balance role when rotating, and reduce the noise generated when rotating. The lower cover plate 5 is covered on the opening of the base 2. The edge of the lower cover plate 5 can be provided with a buckle 501. The buckle 501 can be fastened to the buckle 206 position provided on the upper side wall of the base 2. The number of buckles 501 can be set according to the requirements, such as using left and right buckles to fasten to the side wall of the base 2.
[0046] In this embodiment, the connecting block and the counterweight are connected by the first connecting end 101 and the second connecting end 102 in the connector 1, and the first connecting port 201 and the second connecting port 202 of the base 2. At the same time, the lower cover plate 5 connected to the base 2 is added to improve the stability of the entire mowing module during the mowing process. In addition, the counterweight can ensure dynamic balance in the mowing module when it rotates, reduce the noise generated during rotation, and thus ensure the service life of the entire mowing module and avoid interference with the user.
[0047] like Figure 4 and Figure 6As shown, in one embodiment, the mowing structure 11 further includes a winding member 6, with mowing rope 7 wound around the central axis of the winding member 6. A first movable groove 601 is provided at one end of the winding member 6, and the movable block 3 and the counterweight block 4 are movably connected to the first movable groove 601.
[0048] The winding component 6 includes a central shaft, and a straw rope 7 is circumferentially arranged on the central shaft of the winding component 6. The straw rope 7 is wound around the central shaft in at least one layer or multiple layers. The extension length of the straw rope 7 under different layers is not consistent. At least one layer of circumferential straw rope 7 can be wound on the central shaft. That is, when there are multiple layers of straw rope 7, the straw rope 7 are stacked on each other. The circumference of the outer layer is greater than the circumference of the inner layer. The extension length of the outer layer straw rope 7 from the rope outlet 203 is greater than the extension length of the inner layer straw rope 7 from the rope outlet 203. The first movable groove 601 can be a connecting groove that is interconnected. The movable block 3 can slide in the first movable groove 601. The sliding process can drive the winding component 6 to rotate and then release the rope.
[0049] In this embodiment, the first movable groove 601 adopts a through-type design, allowing the movable block 3 to slide continuously within the groove without the need for additional steering or reset mechanisms, thus reducing the number of mechanical parts and lowering the structural complexity.
[0050] like Figure 3 and Figure 7 As shown, in one embodiment, the other end of the winding member 6 is provided with a mounting groove 602, which is adapted to the reinforcing rib of the lower cover plate 5 near the interior of the base 2.
[0051] Among them, the other end of the winding component 6 corresponding to the first movable groove 601 is provided with a mounting groove 602. The number of mounting grooves 602 can be determined according to the reinforcing ribs of the lower cover plate 5 near the interior of the base 2. After the lower cover plate 5 is placed on the base 2, the reinforcing ribs are adapted to be installed in the mounting grooves 602. In addition, the lower cover plate 5 has notches for stress relief on the reinforcing ribs and the fasteners 501.
[0052] In this embodiment, the other end of the winding component 6 is provided with an installation groove 602, which is directly adapted to the reinforcing rib of the lower cover plate 5. This not only enhances the stability of the winding component 6, but also makes use of the idle space inside the base 2, achieving a compact structure while maintaining structural stability.
[0053] like Figure 2 and Figure 3 As shown, in one embodiment, the mowing structure 11 further includes a rope outlet 8, which includes a clamping plate 801 and a rope outlet 802. The clamping plate 801 is clamped on the side wall of the rope outlet 203 near the base 2, and the rope outlet 802 is correspondingly arranged with the rope outlet 203.
[0054] Among them, the rope outlet 8 can be made of metal, and there are corresponding rope outlets 8 at intervals between the rope outlets 8. The rope can be clamped on the side wall of the base 2 near the rope outlet 203. There is a wire outlet 802 on the plate surface corresponding to the rope outlet 203. The straw rope 7 can extend out from the wire outlet 802 and the rope outlet 203 together to work.
[0055] In this embodiment, after the rope outlet 8 is clamped to the side wall of the base 2, the grass-cutting rope 7 extending from the cable outlet 802 and the rope outlet 203 is more stable and less likely to fall off. The metal rope outlet 8 can reduce the wear of the structure by the grass-cutting rope 7.
[0056] like Figure 4 and Figure 5 As shown, in one embodiment, the base 2 further includes a connecting shaft 204 and an abutment block 205. After the connecting shaft 204 is sleeved on the central shaft, the movable block 3 is connected to the first connecting end 101, the counterweight block 4 is connected to the second connecting end 102, and the movable block 3 abuts against the abutment block 205.
[0057] The diameter of the connecting shaft 204 of the base 2 is smaller than the diameter of the central shaft of the winding component 6. The two can be connected by a sleeve. After the sleeve is completed, the drive of the base 2 can drive the winding component 6 to complete the drive as well. The abutting block 205 of the base 2 can be a structure that protrudes inside the base 2. The movable block 3 abuts against the abutting block 205, so that the movable block 3 can rotate on the abutting block 205.
[0058] In this embodiment, after the connecting shaft 204 is sleeved on the central shaft, the base 2 can drive the winding component 6 to rotate; the counterweight block 4 and the movable block 3 are respectively connected to the two ends of the connecting shaft 204 (the first connecting end 101 and the second connecting end 102), and achieve dynamic balance through the abutment block 205.
[0059] like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in one embodiment, the grass-cutting structure 11 further includes a first through-hole 9, and the movable block 3 includes a first fixing hole 301, a boss 302, and a movable member 303. The first through-hole 9 passes through the first fixing hole 301 and the first connecting port 201 and is connected to the first connecting end 101. The boss 302 abuts against the first movable groove 601, and the movable member 303 abuts against the side wall of the base 2.
[0060] The first through-hole 9 can be a connector 1, such as a nut, that is adapted to the first connecting end 101. The first through-hole 9 can pass through the first fixing hole 301 and the second connecting port 202 simultaneously and be correspondingly set with the first connecting end 101. The boss 302 can be set as a frustum structure, and the protruding structure can be engaged with the side wall of the first movable groove 601. The movable block 3 can rotate on the base 2 in an alternating motion state, thereby driving the winding component 6 to rotate. The straw rope 7 in the winding component 6 is also driven to rotate. The movable block 3 is specifically the movement trajectory of the boss 302 in the first movable groove 601. A stacked plate is provided between the first through-hole 9 and the first connecting end 101. The stacked plate can disperse stress, enhance mechanical strength and fatigue resistance, and avoid deformation or fracture of single-layer material due to stress concentration.
[0061] In this embodiment, the connection stability of the entire structure is significantly improved by the adaptive connection of the first fixing hole 301, the second connecting port 202 and the first through-piece 9, and the snap-fit between the boss 302 and the side wall of the first movable groove 601. The structural design of the boss 302 not only increases the contact area between the movable block 3 and the first movable groove 601, but also provides additional support through the snap-fit mechanism, which helps to enhance the strength and durability of the entire structure.
[0062] like Figure 3 and Figure 6 As shown, in one embodiment, the grass-cutting structure 11 further includes a second threading member 10. The shape of the counterweight 4 is adapted to the first movable groove 601. The counterweight 4 is provided with a second fixing hole 401. The second threading member 10 passes through the second fixing hole 401 and the second connection port 202 and is then connected to the second connection end 102.
[0063] The second through-hole 10 and the first through-hole 9 can have the same structure; the counterweight 4 is a structural component with a central opening; the second through-hole 10 can pass through the second fixing hole 401 and the second connecting port 202 simultaneously and be correspondingly set with the second connecting end 102; and the shape of the counterweight 4 is adapted to the groove structure of the first movable groove 601; a stacked plate is provided between the second through-hole 10 and the second connecting end 102; the stacked plate can disperse stress, enhance mechanical strength and fatigue resistance, and avoid deformation or fracture of single-layer material due to stress concentration.
[0064] In this embodiment, the connection stability of the entire structure is significantly improved by adapting the second fixing hole 401, the second connecting port 202 and the second through-hole 10, and by adapting the counterweight 4 and the first movable groove 601.
[0065] like Figure 3 and Figure 5As shown, in one embodiment, the grass-cutting structure 11 further includes a second through-hole 10. The counterweight 4 is configured as a hollow cylinder. The second through-hole 10 passes through the central through hole and the second connection port 202 of the cylinder and is then connected to the second connection end 102.
[0066] The counterweight 4 can be a cylinder with a hollow design in the middle. The second through-hole 10 passes through the central through hole and the second connection port 202 of the hollow area and is connected to the second connection end 102. At the same time, the counterweight 4 abuts against the corresponding second movable groove on the winding component 6.
[0067] like Figure 3 and Figure 5 As shown, in this embodiment, a double-point fixing structure is formed by simultaneously penetrating the central through hole of the cylinder and the second connecting port 202. During grass cutting operations, the connecting part 1 can be effectively prevented from loosening or breaking due to excessive torque.
[0068] like Figure 6 As shown, in one embodiment, the first movable groove 601 is circumferentially disposed on the bottom surface of the winding member 6. The first movable groove 601 further includes a first slot 6011 and a second slot 6012, and the boss 302 moves between the first slot 6011 and the second slot 6012.
[0069] The number of first movable slots 601 can be more than one, and they can be set in the circumferential direction of the ground of the winding component 6 as needed. The first movable slot 601 can form a travel path for the protrusion 302 of the movable component 303. This travel path is formed by the first slot 6011 and the second slot 6012. The first slot 6011 and the second slot 6012 can be the position points for the movement of the movable block 3. The first slot 6011 and the second slot 6012 are interconnected. The protrusion 302 in the movable block 3 can move in the first slot 6011 and the second slot 6012. During the movement, the winding component 6 is driven to rotate and then the winding component 6 performs rope feeding. It should be noted that the number of first movable slots 601 is more than one, that is, there is more than one first slot 6011 and one second slot 6012. The movable block 3 moves in a circular motion on the first movable slot 601.
[0070] In this embodiment, the movable block 3 can move on the first slot 6011 and the second slot 6012 to drive the winding component 6 to rotate, thereby achieving a stable wire output effect.
[0071] like Figure 9 and Figure 10 As shown in the figure, a garden robot 14 disclosed in this application includes: a connecting structure 12, a mowing structure 11, and a body 13. One end of the connecting structure is connected to the mowing structure 11, and the other end of the connecting structure is connected to the body 13.
[0072] The garden robot 14 includes a connecting structure 12, a mowing structure 11, a front end (not shown), and a body 13. The mowing structure 11 has a swing arm; one end of the swing arm is movably connected to the connecting structure 12, and the other end is fixedly connected to the mowing structure 11. The connecting structure 12 has multiple interconnected connectors 1, each with a corresponding connection position, including a connection position to the self-moving device body and a connection position to the swing arm. The swing arm extends downwards along its length and can swing within a specified range. The range of motion is 0-90 degrees (the direction of swing is from the side of the body 13 of the garden robot 14 to the front of the body 13 of the garden robot 14), and the structure at its end can be movably connected to the connecting structure 12; the front of the garden robot 14 and the body 13 can be connected by a detachable structure, the front can be set at the position in the forward direction of the body 13, and the grass-cutting structure 11 can be set at the rear of the body 13. The grass-cutting structure 11 protrudes relative to the body 13 and the front, which is beneficial for the grass-cutting structure 11 to cut the grass in the boundary area;
[0073] In this embodiment, the grass-cutting structure 11 is connected to the body 13 of the garden robot 14 via the connecting structure 12 in the grass-cutting structure 11. The swing arm in the grass-cutting structure 11 can drive the grass-cutting structure 11 to swing within a certain range. When the garden robot 14 is working, the grass-cutting rope 7 in the grass-cutting structure 11 can cut the grass in the boundary area. Even if the mounting plate in the grass-cutting structure 11 collides with the edge obstacle, the swing arm in the grass-cutting structure 11 can still drive the grass-cutting structure 11 to cut the grass in other areas. In this way, the grass-cutting effect of the garden robot 14 with the grass-cutting structure 11 in the boundary area can be guaranteed.
[0074] The working principle of the mowing structure 11 is as follows: the connector 1 in the mowing module 11 is connected to the drive shaft of the mowing motor. The drive shaft drives the base 2 to rotate as a whole. The rotation will cause the movable block 3 installed on the base 2 to generate centrifugal force and rotate in the first movable groove 601 of the winding component 2. After the winding component 2 is driven, the mowing rope 1 comes out from the rope outlet 203 on the side wall of the base 2.
[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above, which are not provided in detail for the sake of brevity; although this utility model 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; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
