Description

Technical Field

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

[0002] Lawn-mowing robots typically use a high-speed rotating blade to cut lawns. As a core working component, the structural stability and operational safety of the blade directly affect the overall performance of the machine. However, during operation, the blade is susceptible to impacts from foreign objects such as stones, branches, metal fragments, and hard plastics, leading to malfunctions such as blade breakage, blade shaft deformation, and even motor overload. This not only shortens the lifespan of the blade and even the entire machine but may also pose safety hazards due to flying debris. Utility Model Content

[0003] The main purpose of this invention is to provide a blade guard and a lawn mowing robot, which aims to protect the blade and improve its durability and the operational reliability of the lawn mowing robot.

[0004] To achieve the above objectives, the blade guard proposed in this utility model is applied to a lawnmower robot, and the blade guard includes: A housing, the housing including a forward-facing first side and a downward-facing mounting surface, the mounting surface for rotatably mounting a cutter head, the first side being located at the front of the cutter head; and A baffle is disposed on the first side, and the height of the downward protrusion of the baffle is approximately the same as the distance between the mounting surface and the cutter head.

[0005] In one embodiment, the downward protrusion of the baffle is H1, and the relative distance between the mounting surface and the cutter head is L1, satisfying: .

[0006] In one embodiment, the cutter head cover further includes a plurality of baffles, which are spaced apart along the first side, and the downward protrusion of the baffles is greater than the downward protrusion of the baffle.

[0007] In one embodiment, a blade is disposed on the lower side of the cutter head, the downward protrusion of the baffle is H2, and the relative distance between the mounting surface and the blade is L2, satisfying: .

[0008] In one embodiment, the baffle is connected to the rearward side of the baffle plate, and the baffle plate includes a baffle head that protrudes downward from the baffle plate. The front side of the baffle head extends backward at an angle and smoothly transitions to the front side of the baffle plate.

[0009] In one embodiment, the cutter head cover further includes a guard plate extending in a front-rear direction and distributed on the left and right sides of the cover. The end of the baffle is connected to the front end of the guard plate, and the front end of the guard plate is conformally arranged to the front side of the baffle head.

[0010] In one embodiment, the lawnmower robot includes two blades spaced apart from each other on the left and right sides. The blade cover also includes a grass-dividing section located in front of the blades. The grass-dividing section is positioned opposite to the gap between the two blades. The width of the grass-dividing section gradually increases from the front to the rear of the lawnmower robot.

[0011] In one embodiment, the maximum width of the grass-dividing section is not less than the gap between the two blades.

[0012] In one embodiment, the grass-splitting section includes a left side plate and a right side plate connected at the front, and the gap between the left side plate and the right side plate gradually increases from the front to the rear of the lawnmower robot.

[0013] In one embodiment, the front side of the baffle is tilted backward.

[0014] In one embodiment, the housing includes a rearwardly positioned second side, and the cutter head guard extends through the second side in a front-rear direction.

[0015] This utility model also proposes a lawn mowing robot, which includes a blade guard as described above, wherein the blade is rotatably disposed on the lower side of the blade guard.

[0016] The technical solution of this utility model involves setting a baffle on the first side of the housing located in front of the cutter head. The baffle protrudes downwards, meaning it is positioned in front of the lawnmower robot's direction of travel relative to the cutter head. The height of the downward protrusion of the baffle is approximately equal to the distance between the mounting surface and the cutter head; that is, the lower edge of the baffle is almost flush with, slightly higher than, or slightly lower than, the upper surface of the cutter head's rotation plane. This forms a frontal protective barrier without interfering with the normal rotation of the cutter head. When the lawnmower robot moves forward, if there are stones, hard branches, or other protruding debris on the ground ahead, these objects will collide with or be blocked by the baffle before contacting the high-speed rotating cutter head. In this way, the baffle effectively intercepts or deflects hard objects, preventing them from directly impacting the cutter head. This reduces the risk of malfunctions such as cutter head chipping, deformation, or motor overload caused by foreign object impacts, improving the durability of the cutter head and the operational reliability of the lawnmower robot. In addition, the precise matching of the baffle height and the installation gap of the cutter head ensures effective interception of foreign objects in front without excessively obstructing the mowing area or affecting the discharge of grass clippings, thus balancing protective performance and operational efficiency.

[0024] This utility model proposes a cutter head guard.

[0025] Please refer to Figures 1 to 3 In one embodiment of this utility model, the blade guard applied to a lawnmower robot includes: The housing 100 includes a forward-facing first side 110 and a downward-facing mounting surface 130 for rotatably mounting the cutter head 600. The first side 110 is located on the front side of the cutter head 600. A baffle 200 is disposed on the first side 110, and the height of the downward protrusion of the baffle 200 is close to the distance between the mounting surface 130 and the cutter head 600.

[0026] The technical solution of this utility model involves providing a baffle 200 on the first side 110 of the housing 100 located in front of the cutter head 600. The baffle 200 extends downwards, meaning it is positioned in front of the lawnmower robot in the direction of travel, relative to the cutter head 600. The height of the downward protrusion of the baffle 200 is approximately equal to the distance between the mounting surface 130 and the cutter head 600; that is, the lower edge of the baffle 200 is almost flush with, slightly higher than, or slightly lower than, the upper surface of the cutter head 600's rotation plane. This forms a frontal protective barrier without interfering with the normal rotation of the cutter head 600. When the lawnmower robot moves forward, if there are stones, hard branches, or other protruding debris on the ground ahead, these objects will collide with or be blocked by the baffle 200 before contacting the high-speed rotating cutter head 600. In this way, the baffle 200 can effectively intercept or deflect hard objects, preventing them from directly impacting the cutter head 600. This reduces the risk of malfunctions such as blade chipping, deformation, or motor overload caused by foreign object impacts, thus improving the durability of the cutter head 600 and the operational reliability of the lawnmower robot. Furthermore, the precise matching of the baffle 200's height with the installation gap of the cutter head 600 ensures effective interception of foreign objects without excessively obstructing the mowing area or affecting the discharge of grass clippings, thus balancing protective performance and operational efficiency.

[0027] It should be noted that the baffle 200 and the blade disc 600 have a gap in the front-to-back direction to prevent the baffle 200 from interfering with the rotation of the blade disc 600. Without loss of generality, the lawnmower robot includes a chassis 700, and the blade disc 600 and blade disc cover are floatingly mounted on the chassis 700. When the baffle 200 blocks an obstacle, the baffle 200 obstructs the obstacle. Under the reaction force of the obstacle, the blade disc 600 and blade disc cover float upwards to avoid interfering with the movement of the lawnmower robot. Regarding the descriptions of the front, back, left, right, up, and down directions in this solution, the normal operating posture of the lawnmower robot is used as a reference. Front and back are understood as the forward and backward directions of the lawnmower robot, i.e., the length direction; left and right are understood as the two sides in the width direction of the lawnmower robot; up and down are understood as the upper and lower distribution directions of the lawnmower robot, consistent with the vertical direction. The descriptions of the front, back, left, right, up, and down directions in the following text will not be further explained.

[0028] In one embodiment, please refer to Figure 6 and Figure 7 The height of the downward protrusion of the baffle 200 is H1, and the relative distance between the mounting surface 130 and the cutter head 600 is L1, satisfying the following: It is understandable that when H1 / L1 is less than 0.75, the lower edge of the baffle 200 is too high and cannot effectively contact or block hard debris close to the ground, thus weakening its protective effect. When H1 / L1 is greater than 1.05, the baffle 200 may obstruct the cutter head 600, interfering with its mowing and affecting mowing efficiency. By controlling H1 / L1 between 0.75 and 1.05, the lower edge of the baffle 200 is positioned near the upper surface of the cutter head 600 or slightly below the mounting surface 130. This not only intercepts stones, branches, and other foreign objects in front of the robot during its movement, preventing them from directly impacting the high-speed rotating cutter head 600, but also ensures that the cutter head 600 has sufficient working space and a chip removal channel. Thus, without sacrificing mowing performance, the probability of the cutter head 600 being damaged by hard object impacts is reduced.

[0029] In one embodiment, please refer to Figure 2 , Figure 6 and Figure 7 The cutter head guard also includes multiple baffles 300, which are spaced apart along the first side 110. The downward protrusion of the baffles 300 is greater than that of the baffle 200. It can be understood that this embodiment, based on the basic front protection provided by the original baffle 200, adds higher and spaced baffles 300 to contact and block hard debris (such as protruding tree roots, piled grass, or large stones) located at a higher position in front of the cutter head 600 earlier. The baffles 300 with a larger downward protrusion are adjacent to the blades 610 in the cutter head 600 at the same horizontal plane, thus protecting the blades 610. Furthermore, the spaced blades 610 serve both cutting and protection purposes, reducing interference with the cutting of grass by the blades 610. Thus, the baffle 200 and the baffle plate 300 form a dual protection system with high and low coordination: the baffle plate 300 is responsible for protecting the blade 610, and the baffle 200 is responsible for protecting the blade disc 600, thereby achieving more comprehensive and efficient protection for the blade disc 600 as a whole, reducing interference with mowing, and ensuring mowing efficiency.

[0030] Furthermore, in this embodiment, please refer to Figure 2 , Figure 6 and Figure 7 A blade 610 is provided on the lower side of the cutter head 600, the baffle 300 protrudes downward to a height of H2, and the relative distance between the mounting surface 130 and the blade 610 is L2, satisfying the following: It is understandable that when H2 / L2 is below 0.95, the baffle 300 is not high enough to reach hard debris close to the rotating plane of the blade 610, thus limiting its protective effect; while when H2 / L2 exceeds 1.02, the baffle 300 may intrude into the normal rotation area of ​​the blade 610, hindering the blade 610 from performing grass cutting operations. By limiting H2 / L2 to between 0.95 and 1.02, the lower edge of the baffle 300 is almost flush with or slightly higher than the upper surface of the blade 610. This allows it to make contact with and block high or protruding hard blocks, stones, tree roots, and other foreign objects in front of it during the movement of the mowing robot, effectively preventing them from directly impacting the high-speed rotating blade 610. This significantly reduces the risk of the blade 610 chipping, rolling, or damage to the shaft system of the blade disc 600. At the same time, this height design ensures that there is still sufficient space below the blade 610 to complete the mowing and chip removal actions, balancing protection performance and work efficiency. It achieves the best balance between the baffle 300's effective interception of foreign objects in front and minimal interference with the working space of the blade 610.

[0031] In one embodiment, please refer to Figure 2 and Figure 5 The baffle plate 300 is connected to the rearward side of the baffle plate 200. The baffle plate 300 includes a baffle head 310 protruding downward from the baffle plate 200. The front side of the baffle head 310 extends backward at an angle and smoothly transitions to the front side of the baffle plate 200. The connection between the baffle plate 200 and the baffle plate 300 enhances the integrity and stability of the protective structure on the cutter head cover. When the lawnmower robot moves forward, hard debris in front first contacts the front side of the baffle plate 200, and then slides to the area of ​​the baffle plate 300 as it continues to move forward. Because the front side of the baffle head 310 is inclined backward and smoothly transitions to the front side of the baffle plate 200, obstacles such as stones and branches can slide smoothly away along the inclined surface, reducing direct impact on the area of ​​the cutter head 600.

[0032] Regarding the structural form of the baffle 200, please refer to the following in this embodiment: Figure 2 , Figure 5 and Figure 7 The front side of the baffle 200 is angled backward. This means that as the baffle 200 extends downward, it also tilts towards the rear of the mowing robot, with its lower part near the area in front of the blade disc 600, forming an angled surface facing the object. When the mowing robot moves forward, stones, tree roots, or protruding obstacles first contact the front side of the baffle 200. Because this surface is angled backward, the object slides downward and backward relative to this slope as it continues to move forward, smoothly promoting the floating of the blade disc 600 and its guard, reducing the instantaneous impact on the baffle 200 and blade disc 600. Simultaneously, this angled surface, together with the subsequently installed baffle plate 300, grass-dividing section 500, and side guard plate 400, forms a continuous and smooth guiding surface, contributing to flexible protection and reducing the probability of damage to the protective structures such as the baffle 200 and baffle plate 300.

[0033] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 8 The cutter head cover also includes a guard plate 400, which extends in the front-to-back direction and is distributed on the left and right sides of the cover 100. The end of the baffle 200 is connected to the front end of the guard plate 400, and the front end of the guard plate 400 is conformally set to the front side of the baffle head 310. The front contour of the guard plate 400 and the front side of the baffle head 310 are conformally set, that is, they are connected continuously and smoothly in spatial form, forming an overall protective structure surrounding the front and side front of the cutter head 600. When the lawnmower robot encounters hard debris (such as inclined stones, tree roots, or protruding clods of soil) at an angle or to the side front during its movement, these foreign objects are likely to hit the edge of the cutter head 600 or the root of the blade 610, causing local damage. By conformally matching the front end of the guard plate 400 with the front side of the baffle head 310, the entire front protective surface forms a continuous and smooth guide curve, guiding the foreign objects to slide away along the outside of the guard plate 400, preventing them from getting stuck or impacting the working area of ​​the cutter head 600. Meanwhile, the guard plate 400 extends in the front-to-back direction, further enhancing the shielding and protection of the lateral rotation area of ​​the cutter head 600, and together with the baffle 200 and the baffle plate 300, it forms an integrated "front-to-side" protection.

[0034] Furthermore, in this embodiment, please refer to Figure 1 , Figure 4 , Figure 6 and Figure 8 The casing 100 includes a rearward-facing second side 120, with the blade guard extending through the second side 120 in a front-to-back direction. It can be understood that the blade guard forms a through-hole structure behind the blade 600, providing a discharge channel for grass clippings and airflow, allowing the grass clippings ejected by the blade 600 to smoothly diffuse outwards, avoiding blockages inside the guard, especially at the junction of the front and sides of the blade 600. Simultaneously, this opening structure of the blade guard reduces wind resistance during the mowing robot's movement. Furthermore, the complete forward protection system, composed of the baffle 200, baffle 300, and grass-distributing section 500 in the first side 110 area, further optimizes the internal flow field and clipping path through the rear opening, achieving a synergistic improvement in protective performance and operational efficiency, enhancing the mowing robot's continuous operation capability and reliability in high-density grass conditions or humid environments.

[0035] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 5The lawnmower robot includes two blades 600 spaced apart on the left and right sides. The blade cover also includes a grass-dividing section 500 located in front of the blades 600. The grass-dividing section 500 is positioned opposite to the gap between the two blades 600, and its width gradually increases from the front to the rear of the lawnmower robot. This allows the robot to move forward, where dense grass or flexible vegetation first contacts the narrow tip of the grass-dividing section 500. Guided by the gradually widening slope, it is then smoothly and efficiently diverted to the left and right sides, entering the cutting areas of the corresponding blades 600. This prevents the grass from tangling, clogging, or forming uncut corners between the two blades 600, improving mowing uniformity and work efficiency. Simultaneously, the grass-dividing section 500 also acts as a pre-separation and deflector for hard debris such as stones and branches, preventing them from falling directly into the narrow gap between the two blades 600 and avoiding impacts on the inner edge of the blades 600, the transmission mechanism, or the cover connection points, thus reducing the risk of mechanical damage and malfunction. In addition, the grass-cutting section 500, together with the baffle 200, baffle plate 300 and side guard plate 400, form an integrated protection and flow guidance system covering the front center to both sides. Without increasing additional power consumption, it takes into account multiple functions such as efficient grass cutting, smooth debris removal and reliable protection, and improves the adaptability, stability and service life of the lawn mowing robot in complex lawn environments.

[0036] Furthermore, in this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 The maximum width of the grass-dividing section 500 is not less than the gap between the two cutter discs 600. During operation, the gap area of ​​the double-cutter disc 600 structure is prone to grass clippings, entanglement of flexible vegetation, or intrusion of hard foreign objects. If the width of the grass-dividing section 500 is too small, it cannot adequately guide the material in front to flow to both sides, causing some grass or debris to fall directly into the gap. This not only affects the uniformity of cutting but may also jam transmission components or cause damage by impacting the inner side of the cutter discs 600. This embodiment ensures that the grass-dividing section 500 can effectively cover and completely shield the middle area between the two cutter discs 600, forming a continuous and complete front barrier. This ensures that all material entering the area of ​​the cutter discs 600 is effectively diverted to the cutting range of the left and right cutter discs 600, preventing material accumulation or direct entry of foreign objects into the middle area.

[0037] In this embodiment, please continue to refer to... Figure 2 , Figure 4 and Figure 5The grass-distributing section 500 includes a left side plate 510 and a right side plate 520 connected at the front. From the front to the rear of the lawnmower robot, the gap between the left side plate 510 and the right side plate 520 gradually increases. Without loss of generality, the front of the grass-distributing section 500 is connected to the baffle 200, presenting a configuration where the left side plate 510, the right side plate 520, and the baffle 200 are connected. In the rearward direction, the gap between the left side plate 510 and the right side plate 520 gradually increases, forming a V-shaped or trumpet-shaped flow-guiding structure that is narrower at the front and wider at the rear. This solves the technical problems of concentrated grass flow in the middle area, poor debris removal, and easy jamming of foreign objects in the gaps of the blade disc 600 during operation of the dual-blade 600 lawnmower robot. When grass or debris comes into contact with the front end of the grass separating section 500, the left side plate 510 and the right side plate 520 converge at the front end to form a sharp point, precisely cutting into the center of the vegetation. As it extends backward, the gap between the two plates gradually widens, guiding the grass material smoothly and orderly to the left and right sides, respectively, into the cutting areas of the corresponding cutter discs 600. This prevents grass clippings from accumulating, tangling, or forming uncut strips between the two cutter discs 600. Simultaneously, the gradually expanding grass separating section 500 actively separates and deflects hard foreign objects such as stones and branches, preventing them from falling directly into the gaps between the cutter discs 600 along a straight path. This reduces the risk of damage to the inner side of the cutter discs 600, the transmission mechanism, or the connection points of the protective cover due to impact from foreign objects. Furthermore, the gap between the left side plate 510 and the right side plate 520 provides deformation space for the grass separating section 500, reducing the probability of damage to the grass separating section 500, and also reduces the weight of the cutter disc cover, facilitating the floating of the cutter discs 600 and the cutter disc cover when encountering foreign objects.

[0038] This utility model also proposes a lawnmower robot, which includes a blade guard. The specific structure of the blade guard is as described in the above embodiments. Since this lawnmower robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here. Please refer to... Figure 1 The cutter head 600 is rotatably disposed on the lower side of the cutter head cover and simultaneously located on the lower side of the chassis 700.

[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
