[0026] In the cleaning device for lawnmowers in this embodiment, since the orientation mechanism restricts the rotation direction of the support wheel, when the lawnmower moves in the opposite direction to detach from the cleaning device, the support wheel is restricted from rotating under the reverse action, so that the lawnmower can generate displacement relative to the support assembly and complete the separation. This avoids the support wheel rotating with the lawnmower and affecting the detachment process, and helps to achieve convenient separation between the lawnmower and the cleaning device.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Lawn mowers are widely used in landscaping, lawn maintenance, and other similar applications, typically relying on wheels for movement and positioning. In practice, lawn mowers often operate in environments with abundant grass and weeds, or complex ground conditions. During operation, the wheels can easily become entangled in weeds, mud, and other debris. This accumulation can affect the wheels' rotation, negatively impacting the machine's smoothness and reliability. Traditional lawn mower cleaning often relies on manual operation, which is inconvenient and inefficient.

[0032] Based on this, see Figures 1 to 6As shown, this embodiment of the invention provides a cleaning device 10 for a lawnmower, which includes a mounting base 100, a support assembly 200, and a cleaning brush 300. The support assembly 200 includes a support wheel 210 and a directional mechanism 220. The support wheel 210 is used to support the lawnmower and is rotatably connected to the mounting base 100. The directional mechanism 220 is connected to the mounting base 100 and the support wheel 210, and is configured such that the support wheel 210 rotates only in a first direction. The cleaning brush 300 is disposed on the mounting base 100 and is used to contact and clean the moving wheels of the lawnmower.

[0033] In the lawnmower cleaning device 10 of this embodiment, by setting a cleaning brush 300 on the mounting base 100 and making the cleaning brush 300 contact the moving wheel of the lawnmower for cleaning, when the lawnmower is used in conjunction with the cleaning device 10, weeds, soil and other debris attached to the surface of the moving wheel can be directly cleaned, thereby improving the problem of the moving wheel not rotating smoothly due to the accumulation of debris, reducing the reliance on manual cleaning operations, and helping to improve the walking stability and reliability of the lawnmower under complex ground conditions.

[0034] Specifically, when the lawnmower enters the working area of ​​the cleaning device 10, the moving wheel first contacts the cleaning brush 300. With the operation of the lawnmower's drive motor or the action of external thrust, the moving wheel rotates, and the bristles of the cleaning brush 300 bend and deform under friction, applying shearing and peeling forces to the debris adhering to the surface of the moving wheel. If the debris is loose soil, the sweeping action of the bristles can directly remove it; if the debris is tangled grass stems, the rotating moving wheel causes relative movement between the grass stems and the bristles, and the rigid support of the bristles can cut the grass stems or forcibly peel them off the wheel surface. During this process, the removed debris falls to the ground under gravity or is discharged through a pre-set debris removal channel, avoiding secondary accumulation. Optionally, the cleaning brush 300 can also be configured as a reciprocating oscillating or rotating structure, further improving cleaning efficiency by increasing the relative speed between the bristles and the surface of the moving wheel.

[0035] In the lawnmower cleaning device 10 of this embodiment, the lawnmower is supported by a support assembly 200, and a directional mechanism 220 is provided between the support wheel 210 and the mounting base 100, so that the support wheel 210 rotates only in a first direction. When the lawnmower performs a cleaning operation, the support wheel 210 can rotate in the first direction under the action of the directional mechanism 220, so that the moving wheel of the lawnmower is in a relatively free-spinning state, ensuring the stable placement of the lawnmower, thereby enabling the cleaning brush 300 to perform a cleaning operation on the surface of the moving wheel.

[0036] Furthermore, the surface of the support wheel 210 may be provided with anti-slip texture or a high coefficient of friction coating to increase the friction between it and the moving wheel of the lawnmower, preventing the lawnmower from shifting unexpectedly when the cleaning brush 300 applies resistance.

[0037] Specifically, the cleaning brush 300 can be made of nylon, steel wire, or abrasive composite materials. The hardness and length of the bristles can be adjusted according to the type of debris to be cleaned. For example, for sticky soil, a harder steel wire brush can be used to enhance the scraping effect; for tangled weeds, a more resilient nylon brush can be used to avoid damaging the anti-slip texture on the surface of the moving wheel. The contact pressure between the cleaning brush 300 and the moving wheel can be adjusted by an elastic element, which can be a coil spring, leaf spring, or rubber block. The deformation of the elastic element provides a constant preload, ensuring that the cleaning brush 300 maintains effective contact even when the surface of the moving wheel is uneven. Furthermore, the arrangement of the cleaning brush 300 is not limited to a single row of bristles. In some embodiments, it can be configured as multiple rows of bristles arranged in a staggered pattern, or a spirally distributed brush roller structure, to increase the cleaning coverage area per unit time.

[0038] Specifically, the support wheel 210 is provided with a locking groove 2121, and the orientation mechanism 220 is provided with a locking tooth 2211; when the support wheel 210 rotates in the first direction, the locking tooth 2211 is at least partially separated from the locking groove 2121, and when the support wheel 210 rotates in the opposite direction in the first direction, the locking tooth 2211 engages with the locking groove 2121.

[0039] The geometry of the locking groove 2121 can be designed as a unidirectional inclined surface structure, a sawtooth structure, or an arc-shaped groove structure. In some embodiments, the sidewall of the locking groove 2121 includes a gentle guide surface and a steep limiting surface, wherein the guide surface faces a first direction and the limiting surface faces the opposite direction of the first direction. When the support wheel 210 rotates in the first direction, the end of the locking tooth 2211 slides along the guide surface and gradually rises or retracts, thereby crossing the ridge of the locking groove 2121 to enter the next groove or remaining in a separated state. The resistance generated in this process is small, allowing the support wheel 210 to rotate smoothly. Conversely, when the support wheel 210 attempts to rotate in the opposite direction, the end face of the locking tooth 2211 directly abuts against the limiting surface. Since the angle of the limiting surface is close to vertical or has a large friction angle, the locking tooth 2211 cannot slide over it and is thus firmly locked in the locking groove 2121, achieving mechanical locking.

[0040] The number of locking teeth 2211 and locking grooves 2121 that engage can be adjusted according to the required locking torque. Optionally, multiple locking grooves 2121 can be evenly distributed on the circumference of the support wheel 210, such as 6, 12, or 24, and the corresponding orientation mechanism 220 is provided with one or more locking teeth 2211 that engage with them. If the number of locking grooves 2121 is too large, the depth of a single groove may be shallow, resulting in a reduced contact area during locking, which can easily lead to tooth tip breakage or plastic deformation when subjected to a large reverse impact force; if the number is too small, the step angle of the support wheel 210 in the free rotation direction will be large, which may cause obvious jerking during the movement of the lawnmower, affecting the stability of walking.

[0041] When the support wheel 210 rotates in the first direction, the locking tooth 2211 separates from the locking groove 2121 as the support wheel 21 rotates. At this time, the directional mechanism 220 will not limit the rotation of the support wheel 210. When the moving wheel moves in the opposite direction, the directional mechanism 220 can limit the rotation of the support wheel 210 so that the moving wheel can separate from the support wheel 210.

[0042] The specific mechanical transmission path of this process is as follows: When the lawnmower enters normally or moves forward during cleaning operations, its moving wheels drive the support wheel 210 to rotate in the first direction. At this time, the contour of the locking groove 2121 pushes the locking tooth 2211 to displace (such as swinging around the hinge point or compressing axially), causing the locking tooth 2211 to disengage from or slide through the locking groove 2121, and the support wheel 210 is in a "free-spinning" or "following" state. This state allows the lawnmower to maintain positional stability through the rolling of the support wheel 210 even under the resistance of the cleaning brush 300, avoiding wear caused by the moving wheels being forcibly dragged on the ground or the equipment lurching forward.

[0043] Conversely, when the lawnmower needs to exit the cleaning device 10 or is unexpectedly subjected to a reverse thrust, the moving wheel attempts to drive the support wheel 210 to rotate in the opposite direction. At this time, the locking teeth 2211 quickly fall into and lock onto the limiting surface of the locking groove 2121 under the action of the reverse torque. Since the orientation mechanism 220 is fixed to the mounting base 100, the reverse rotation of the support wheel 210 is forcibly prohibited, and the support wheel 210 becomes stationary or in a sliding friction state relative to the ground. In this state, if the moving wheel of the lawnmower continues to exert force in the opposite direction, the static friction between it and the support wheel 210 will be broken, causing the moving wheel to slip or climb on the surface of the support wheel 210, thereby achieving effective separation of the moving wheel and the support wheel 210. This mechanism utilizes the one-way locking characteristic, which not only ensures stability during operation but also provides convenience when exiting, without the need for additional manual unlocking operations.

[0044] Furthermore, the orientation mechanism 220 includes a locking member 221 and a locking spring 222. The locking teeth 2211 are provided on the locking member 221, and the locking spring 222 is used to drive the locking teeth 2211 to engage with the locking groove 2121.

[0045] The specific selection of the locking spring 222 can be determined based on the installation space and the required preload, and its form is not limited to a helical compression spring, helical tension spring, disc spring, or leaf spring. In some embodiments, the locking spring 222 is configured to always be in a compressed state to provide continuous axial or radial thrust, ensuring that the locking teeth 2211 can automatically reset and penetrate into the locking groove 2121 when there is no external force interference. This elastic drive mechanism can compensate for the gap caused by mechanical wear, ensure the tightness of the engagement between the locking teeth 2211 and the locking groove 2121, and prevent accidental disengagement due to vibration. When the support wheel 210 rotates in the first direction, forcing the locking teeth 2211 to exit the locking groove 2121, the locking spring 222 undergoes elastic deformation and stores potential energy; once the external driving force disappears or changes direction, the stored potential energy is immediately released and converted into a reset driving force, pushing the locking member 221 to quickly return to its original position, preparing for the next locking action.

[0046] In one embodiment, the locking member 221 is coaxially arranged with the support wheel 210, and the locking spring 222 is used to drive the locking member 221 to move along the axial direction of the support wheel 210 toward the locking groove 2121.

[0047] In this embodiment, the locking member 221 can be designed as a sleeve structure fitted onto the rotating shaft of the support wheel 210, or as part of the hub of the support wheel 210. The locking groove 2121 is correspondingly formed on the end face or side face of the support wheel 210, arranged in a circular array. The locking spring 222 can be placed between the locking member 221 and the fixed end of the mounting base 100, or placed in a blind hole inside the locking member 221. When the support wheel 210 rotates forward, the inclined surface of the locking groove 2121 presses against the locking teeth 2211, pushing the locking member 221 to move slightly backward along the axial direction against the spring force, thus achieving disengagement; when locking is required, the spring force pushes the locking member 221 axially forward, causing the locking teeth 2211 to engage in the groove. The advantage of this axial engagement method is that it has a large force-bearing area, can withstand a large reverse torque, and the structural center of gravity is concentrated on the rotation axis, which helps maintain the dynamic balance of the support wheel 210 and reduces vibration during high-speed rotation.

[0048] This arrangement allows for a more compact combination of the locking element 221 and the support wheel 210, making it particularly suitable for use in lawnmower chassis spaces where installation height is strictly limited. Because the components are stacked axially, the radial dimension is reduced, allowing the cleaning device 10 to be designed more flat, lowering the ground clearance requirement when the lawnmower passes through. Furthermore, the coaxial arrangement facilitates sealing and dust prevention; a sealing ring can be placed between the locking element 221 and the support wheel 210 to prevent dirt from entering the spring cavity and affecting its elasticity. In other embodiments, the locking element 221 can also be located on the radial side of the support wheel 210. When the support wheel 210 moves along the first direction, the locking element 221 can move away from the outer wall of the support wheel 210 under the driving action of the inner wall of the locking groove 2121, thereby separating the locking teeth 2211 from the locking groove 2121.

[0049] In this embodiment, the locking member 221 is typically hinged or slidably connected to the bracket of the mounting base 100, and its position corresponds to the outer circumferential surface of the support wheel 210. The locking groove 2121 is formed on the rim or outer surface of the support wheel 210. One end of the locking spring 222 is connected to the mounting base 100, and the other end acts on the locking member 221, providing radial pressure towards the center of the support wheel 210. When the support wheel 210 rotates forward, the rising slope of the locking groove 2121 contacts the locking tooth 2211, converting the rotational motion into a radially outward displacement of the locking member 221, thereby compressing the locking spring 222 and causing the locking tooth 2211 to lift and disengage; when a reverse rotation tendency occurs, the vertical surface of the locking groove 2121 blocks the locking tooth 2211, and forms a rigid lock under the action of the spring force.

[0050] Alternatives to the radial arrangement include designing the locking element 221 as a swing lever structure, utilizing the lever principle to amplify or reduce the spring force to accommodate different locking torque requirements. Optionally, a roller or slider can be provided at the bottom of the locking element 221 to reduce wear from friction with the surface of the support wheel 210. Compared to the coaxial arrangement, the radial arrangement facilitates later maintenance and repair because the locking element 221 is exposed on the outside, allowing for observation of the wear condition of the locking teeth 2211 or replacement of the locking spring 222 without disassembling the support wheel 210.

[0051] Specifically, the support wheel 210 includes a wheel body 211, an end cap 212, and a support shaft 213. The support shaft 213 is connected to the mounting base 100. The end cap 212 is rotatably connected to the support shaft 213 via a bearing 214. The wheel body 211 is connected to the end cap 212 and is used to contact the moving wheel. A locking groove 2121 is provided on the end cap 212.

[0052] The wheel body 211 can be made of engineering plastics, rubber-coated metal, or high-strength aluminum alloy to adapt to different ground friction coefficients and load requirements. In some embodiments, the outer surface of the wheel body 211 can be provided with anti-slip ribs or a high-friction coating to increase the grip between the wheel and the lawnmower's moving wheel and prevent relative slippage when the cleaning brush 300 applies resistance. The end cap 212 not only serves as the carrier of the locking groove 2121 but also plays a sealing and protective role. Its edge can extend to form a dustproof lip, covering the outside of the bearing 214 to prevent weed debris and mud from entering the bearing. The locking groove 2121 can be directly molded onto the side end face of the end cap 212, or a groove can be machined into the end cap 212. Alternatively, an independent carbide toothed ring can be embedded in the end cap 212 as the implementation of the locking groove 2121 to improve wear resistance and impact resistance.

[0053] In this embodiment, the support shaft 213 serves as a carrier connecting the support wheel 210 to the mounting base 100. When the wheel body 211 rotates relative to the mounting base 100, the wheel body 211 can rotate relative to the support shaft 213 through the support of the bearing 214.

[0054] During rotation, bearing 214 also bears radial load and part of the axial load. When the lawnmower's moving wheel presses against the wheel body 211, the resulting vertical pressure is transmitted through end cap 212 to the outer ring of bearing 214, and then through the rolling elements to the support shaft 213. This force transmission path ensures that the wheel body 211 can rotate stably around the support shaft 213 without radial runout or axial movement. In addition, the presence of bearing 214 allows end cap 212 and locking groove 2121 to rotate synchronously and with high precision with the wheel body 211, ensuring accurate engagement of locking teeth 2211 and locking groove 2121, and avoiding locking failure or mechanical interference due to rotational lag.

[0055] In one embodiment, the number of bearings 214 can be at least two to improve the smoothness of rotation of the wheel body 211. When two bearings 214 are provided, they can be arranged axially spaced along the support shaft 213, located at different depths at both ends of the end cap 212 or at the same end. This dual-support structure forms a stable cantilever beam or simply supported beam effect, which can effectively resist the overturning moment generated by the wheel body 211 when subjected to eccentric load. For example, when the lawnmower's wheel moves on one side and presses against the edge of the support wheel 210, the dual-bearing configuration can distribute the contact stress, prevent the end cap 212 from tilting and jamming, and ensure continuous and smooth rotation.

[0056] In one embodiment, the mounting base 100 includes an upper cover 110 and a base 120. The upper cover 110 is connected to the base 120 and forms a shaft hole 121. A support shaft 213 is disposed in the shaft hole 121. The upper cover 110 has a wheel hole 111 and a cleaning hole 112. A cleaning brush 300 passes through the cleaning hole 112, and a support wheel 210 passes through the wheel hole 111.

[0057] In this embodiment, the inner wall of the shaft hole 121 may be machined with a positioning step or keyway for axially limiting or circumferentially fixing the support shaft 213 to prevent relative rotation of the support shaft 213 when subjected to torque.

[0058] This split structure allows core components such as the support shaft 213, bearing 214, and end cap 212 to be pre-assembled on the base 120 before being fastened to the top cover 110 for sealing, thus avoiding the difficulties of long-distance insertion and installation from a single direction. The compact design reduces the vertical space occupied by the mounting base 100, allowing the lawnmower cleaning device 10 to be installed closer to the ground, lowering the overall center of gravity and improving the equipment's anti-tipping ability during operation. Furthermore, the mating surface between the top cover 110 and the base 120 can be designed as a labyrinth seal or equipped with sealing strips to prevent external moisture and dust from directly penetrating the interior through the joints, protecting the support shaft 213 and bearing 214 from corrosion.

[0059] Furthermore, the upper cover 110 and the base 120 are detachably connected by fasteners. The upper cover 110 has a connection hole 113, and the fastener passes through the connection hole 113 and is connected to the base 120. The mounting base 100 also includes a sealing element 130, which covers the connection hole 113.

[0060] Fasteners can be bolts, screws, or self-tapping screws, and their material should have a certain degree of corrosion resistance, such as stainless steel or galvanized carbon steel. The number and distribution of the connecting holes 113 can be adjusted according to the size of the mounting base 100 and the stress conditions. Typically, at least two are evenly distributed circumferentially to ensure uniform clamping force between the top cover 110 and the base 120, preventing seal failure due to localized warping. The material of the seal 130 can be rubber, silicone, or thermoplastic elastomer. The seal 130 not only covers the opening of the connecting hole 113 but also extends to the surrounding planar area, forming a surface seal that effectively blocks the path of liquid seeping into the internal cavity along the fastener thread gaps during cleaning. During cleaning, moisture easily accumulates on the equipment surface. The presence of the seal 130 makes the area of ​​the connecting hole 113 a barrier against weak points in waterproofing, preventing moisture from contacting the internal metal fasteners and the end of the support shaft 213, thereby avoiding disassembly difficulties or structural strength reduction caused by corrosion. Optionally, the surface of the seal 130 may be designed with water-guiding patterns or protrusions to guide water flow away quickly and reduce water retention time. In addition, the seal 130 may also have a certain degree of elastic deformation capability to adapt to the thermal expansion and contraction differences between the top cover 110 and the base 120 caused by temperature changes, ensuring continuous and effective sealing contact.

[0061] In one embodiment, the upper cover 110 is further provided with a mounting groove 1131, the opening of the connecting hole 113 is located in the mounting groove 1131, and the sealing member 130 is accommodated in the mounting groove 1131.

[0062] The depth of the mounting groove 1131 can match the thickness of the seal 130, or be slightly less than the thickness of the seal 130, so that the seal 130 presents a slightly convex state after installation, utilizing its pre-compression to provide additional sealing pressure. This recessed design avoids the risk of the seal 130 protruding from the surface of the cover 110 and being scratched or snagged externally, improving the durability of the device. The edges of the mounting groove 1131 can be chamfered or rounded to prevent scratching of the seal 130 during assembly.

[0063] The sidewalls of the mounting groove 1131 prevent radial displacement of the seal 130 during assembly, ensuring its alignment accuracy with the connecting hole 113, simplifying the worker's operation process, and improving production efficiency. The compact layout results in a smooth and flat surface for the mounting base 110, reducing the possibility of debris adhesion and facilitating subsequent cleaning and maintenance. Alternatively, the shape of the mounting groove 1131 is not limited to a circle; it can also be a polygonal or irregular shape consistent with the seal 130. Even a locating pin or snap-fit ​​can be installed within the mounting groove 1131 to cooperate with the corresponding structure on the seal 130, enabling tool-free quick installation and replacement. This modular design allows the seal 130 to be easily replaced after aging or damage, extending the service life of the entire lawnmower cleaning device 10.

[0064] Furthermore, the cleaning device 10 also includes a disassembly assembly 400, which includes an unlocking member 410, a snap-fit ​​member 420, and a resetting member. The unlocking member 410 is throttle-connected to the snap-fit ​​member 420, and the resetting member is used to drive the snap-fit ​​member 420 to reset. The snap-fit ​​member 420 is used to snap-fit ​​and fix with an external component, and the unlocking member 410 is used to drive the snap-fit ​​member 420 to separate from the external component.

[0065] The core design of the disassembly and assembly component 400 lies in achieving a balance between "quick installation and disassembly" and "self-locking retention." In some embodiments, the snap-fit ​​component 420 can be designed as a snap with a flexible barb structure, a sliding pin, or a rotating locking tongue. When the cleaning device 10 is pushed towards the cleaning chamber 20 (external component) of the cleaning base station 1, the guide slope of the snap-fit ​​component 420 is temporarily retracted by the pressure of the external component. Once the locking position is reached, the reset component (such as a spring) immediately pushes the snap-fit ​​component 420 to pop out or reset, so that it snaps into the corresponding groove or hole of the external component and locks in place. This automatic snap-fit ​​mechanism can complete the installation without additional tools, greatly improving the user experience and ease of disassembly and assembly. The unlocking process is a controlled mechanical linkage process. The user inputs the unlocking command by pressing, flicking, or pulling the unlocking component 410. At this time, the movement of the unlocking component 410 is converted into the reverse movement of the snap-fit ​​component 420, forcing it to overcome the elasticity of the reset component and disengage from the engagement state with the external component. When the user releases the unlocking component 410, the elastic potential energy stored in the reset component is released, pushing the locking component 420 back to its initial locked position. This reset action not only prepares for the next installation, but also prevents the cleaning device 10 from accidentally falling off when the locking component 420 remains in the unlocked position due to gravity or inertia, in the instant when the unlocking component 410 is not continuously pressed.

[0066] Specifically, the unlocking component 410 is provided with a driving part 413, and the latching component 420 is provided with a driving surface 4221. The driving part 413 and the driving surface 4221 are in sliding contact, and the driving surface 4221 is set at an angle to the moving direction of the latching component 420.

[0067] The engagement of the drive unit 413 and the drive surface 4221 constitutes a typical cam mechanism or inclined plane transmission mechanism. The tilt angle (i.e., pressure angle) of the drive surface 4221 is a key design parameter, typically selected between 15° and 45°, such as 20°, 30°, or 40°. If the angle is too small, although effort is reduced, a longer operating stroke is required to complete the unlocking, resulting in a lengthy structure; if the angle is too large, although the stroke is short, the transmission efficiency decreases, the required pressing force increases, and a large lateral force is easily generated, causing the locking element 420 to jam in the guide rail. The end of the drive unit 413 can be designed as an arc surface or a roller to reduce the coefficient of friction when sliding with the drive surface 4221, improve the smoothness of transmission, and extend its service life.

[0068] In this embodiment, the drive unit 413, through sliding engagement with the drive member 4221, allows the unlocking member 410 and the latching member 420 to move in different directions. For example, pressing down on the unlocking member 410 can drive the latching member 420 to move horizontally. This orthogonal motion conversion design (vertical input, horizontal output) greatly optimizes the ergonomic layout. The user can conveniently apply a vertical downward pressing force from the top or side of the cleaning device 10, while the latching member 420 retracts horizontally inside, thereby releasing the lock on the lawnmower chassis. This layout makes the operating space more flexible and not limited by surrounding obstacles. For example, even if the cleaning device 10 is installed low, the user only needs to lean down and press down to unlock it, without having to reach under the device to laterally pry open the latch.

[0069] In one embodiment, the mounting base 100 has a mounting cavity 122 inside, the unlocking member 410 and the resetting member are disposed in the mounting cavity 122, and the mounting base 100 also has an active hole 123 communicating with the mounting cavity 122, and the snap-fit ​​member 420 at least partially protrudes from the active hole 123.

[0070] The design of the mounting cavity 122 provides a closed and protected operating environment for the assembly / disassembly component 400. The size of the movable hole 123 needs to be slightly larger than the cross-sectional size of the snap-fit ​​component 420 to allow for necessary movement clearance. If the clearance is too small, when dirt, grass clippings, or ice chips enter the movable hole 123, it can easily cause the snap-fit ​​component 420 to jam and fail to pop out or retract; if the clearance is too large, it may reduce the positioning accuracy of the snap-fit ​​component 420 when it engages with external components, and may even produce abnormal noise under high-frequency vibration.

[0071] By providing a mounting cavity 122 to accommodate the disassembly / removal component 400, the component 400 can be combined with the mounting base 100 to form a modular structure, facilitating installation and replacement. This modular design allows the disassembly / removal component 400 to be pre-assembled and tested as an independent sub-assembly. On the production line, the unlocking component 410, the snap-fit ​​component 420, and the reset component can be assembled and tested within the mounting cavity 122 to ensure flexible and reliable operation. Afterward, the mounting base 100 can be sealed using snaps, screws, or ultrasonic welding. When the disassembly / removal component 400 wears or is damaged due to prolonged use, maintenance personnel do not need to replace the entire mounting base 100; they can simply open the inspection cover of the mounting cavity 122 or directly remove the damaged module for replacement, significantly reducing maintenance costs and downtime.

[0072] Specifically, the mounting base 100 is provided with a guide groove 1231 that is connected to the mounting cavity 122 and the movable hole 123 respectively, and the snap-fit ​​member 420 is slidably engaged with the guide groove 1231.

[0073] The cross-sectional shape of the guide groove 1231 can closely match the contour of the snap-fit ​​component 420, such as rectangular, T-shaped, or dovetail-shaped, to restrict the degree of freedom of the snap-fit ​​component 420 during movement, ensuring that it can only move along a preset straight trajectory. The depth and length of the guide groove 1231 should be designed according to the maximum stroke of the snap-fit ​​component 420, and a limiting step should be provided at the end to prevent the snap-fit ​​component 420 from being excessively ejected and detached from the mounting base 100 under the elastic force of the reset component, or from being completely pushed into the depth of the mounting cavity 122 and misaligned during the unlocking operation.

[0074] Precise guidance ensures that the latching component 420 maintains the same movement path during each unlocking and resetting, preventing one-sided wear or jamming due to skew. Especially in the operating environment of a lawnmower, where the equipment may be subjected to impacts and vibrations from all directions, the guide groove 1231 effectively restrains the latching component 420, preventing fretting wear or accidental displacement due to vibration, thereby maintaining the stability of the locked state. Furthermore, the guide groove 1231 also serves as part of a dust barrier, reducing the chance of external impurities directly entering the mating surface between the latching component 420 and the mounting base 100.

[0075] In one embodiment, the snap-fit ​​component 420 includes a snap fastener 421 and a connecting frame 422. The snap fastener 421 is disposed on the connecting frame 422. The connecting frame 422 is slidably engaged with the guide groove 1231, and the driving surface 4221 is disposed on the connecting frame 422. The snap fastener 421 protrudes from the movable hole 123 and is used to snap-fit ​​with an external component.

[0076] Specifically, the number of latches 421 can also be multiple, arranged along the moving direction (or extending direction) of the connecting frame 422. In this case, the latches 421 can achieve multiple-point engagement with external components, improving the installation stability of the cleaning device 10. The multi-latch design adopts a redundant safety strategy. When two or more latches 421 are provided, they can be arranged at intervals along the length of the connecting frame 422, respectively engaging in multiple corresponding locking holes or grooves on the external components. This distribution method can disperse the shear force, bending moment, and torque on the cleaning device 10 to multiple stress points, avoiding stress concentration and plastic deformation caused by excessive force at a single point. For example, when the cleaning device 10 is subjected to a lateral impact, the front and rear latches 421 can form a couple, effectively resisting the overturning moment and preventing the device from rotating and loosening. In addition, the multi-latch layout can also provide graded locking or fault-tolerant functions. If a locking hole of an external component is blocked by a foreign object or cannot be fully engaged due to manufacturing tolerances, the other latches 421 can still maintain an effective locking state to ensure that the equipment will not fall off.

[0077] Furthermore, the reset component also includes a first spring 431, which is connected to the connecting frame 422 and the mounting base 100 respectively, and the first spring 431 is used to drive the connecting frame 422 to reset.

[0078] The first spring 431 is the power source for the disassembly and assembly assembly 400, and its performance directly determines the reliability of locking and the feel of unlocking. The first spring 431 is typically a compression coil spring, installed between the tail of the connecting bracket 422 and the rear wall of the mounting cavity 122. The first spring 431 can be installed by sleeve on a guide post extending from the connecting bracket 422, or by placing it in a spring seat at the bottom of the mounting cavity 122. To prevent lateral bending (buckling) of the spring during compression, an appropriate gap should be maintained between the diameter of the guide post and the inner diameter of the spring, or a protective sleeve should be provided on the outside of the spring. Furthermore, both ends of the spring should be ground flat to ensure perpendicular contact with the contact surface, avoiding premature failure due to off-center loading.

[0079] This design allows the connecting bracket 422 to quickly spring back to the locked position the instant the user releases the unlocking component 410. This not only shortens the time window for returning from the unlocked state to the locked state, reducing the risk of misoperation, but also provides timely feedback force during dynamic installation processes (such as when quickly pushing in the cleaning device 10), helping the latch 421 to smoothly slide over the protrusions of the external component and fall into the locking position.

[0080] Specifically, the unlocking component 410 includes an unlocking part 411 and a connecting part 412. The driving part 413 and the unlocking part 411 are respectively disposed on the connecting part 412, and the unlocking part 411 is used to drive the connecting part 412 to move so as to drive the card connector 420 to move.

[0081] In some embodiments, the outer surface of the unlocking part 411 may be designed with anti-slip texture, recessed finger grooves, or wing plates to increase the contact area, so that the user can apply force steadily even when wearing gloves or with wet hands. The connecting part 412 acts as a force transmission bridge, converting the external operating force (such as pressing pressure) received by the unlocking part 411 into a thrust of the driving part 413 on the latching member 420. The connection between the connecting part 412 and the driving part 413 can be rigidly integrally formed to ensure lossless force transmission; or it can be hinged by a pin, allowing for slight angle adaptation to compensate for assembly stress caused by manufacturing tolerances. When the unlocking part 411 is pressed, the connecting part 412 drives the driving part 413 to slide along the inclined plane, forcing the latching member 420 to overcome the elastic force of the first spring 431 and make lateral displacement, thereby achieving unlocking.

[0082] The number of connecting parts 412 can be multiple, for example, two connecting parts 412 can be symmetrically arranged, and each connecting part 412 is equipped with a first spring 431, thereby improving the reset efficiency and the reset stability of the unlocking component 410. The symmetrical layout of the two connecting parts 412 and the two first springs 431 constitutes a typical "double guide rail double reset" mechanism. This design significantly improves the system's resistance to off-center loads: when the user operates the unlocking component 410, if the point of force application is slightly off-center, the single-sided structure is prone to tilting and jamming, while the symmetrical double-sided structure can constrain each other, forcing the unlocking component 410 to maintain vertical or linear movement, avoiding a surge in friction caused by tilting. At the same time, the two first springs 431 work in parallel, which not only provides a larger total reset force, ensuring reliable reset even in low-temperature environments or when the springs partially fail, but also makes the force distribution more uniform, extending the service life of the springs and guide structures. In addition, the symmetrical layout also helps to balance internal stress and reduce the risk of deformation of the mounting base 100 due to excessive force on one side.

[0083] In one embodiment, the mounting base 100 has an unlocking hole 114, and the unlocking part 411 slides in conjunction with the unlocking hole 114.

[0084] The unlocking hole 114 not only provides precise movement guidance for the unlocking part 411, but also acts as a protective barrier. The inner wall of the unlocking hole 114 can form a tight but smooth clearance fit with the outer contour of the unlocking part 411, effectively preventing foreign objects such as grass clippings, dirt, and small stones from entering the mounting cavity 122, thus preventing impurities from interfering with the normal operation of the disassembly and assembly assembly 400. At the same time, this fit structure restricts the degree of freedom of the unlocking part 411, ensuring that it can only move along the preset unlocking trajectory, preventing damage to the mechanism caused by lateral forces.

[0085] Furthermore, the reset member includes a second spring 432, which is connected to the mounting base 100 and the connecting portion 412 respectively, and the second spring 432 is used to drive the unlocking member 410 to reset.

[0086] The introduction of the second spring 432 completes the dual reset logic of the disassembly and assembly assembly 400. The first spring 431 is mainly responsible for locking the ejection of the latch 420, while the second spring 432 is specifically responsible for pushing the unlocking member 410 back to its initial inactive position. This division of labor decouples the two actions: even if the latch 420 fails to fully reset due to foreign object obstruction, the second spring 432 can still ensure that the unlocking member 410 returns to its original position, preventing the unlocking member 410 from being under pressure for a long time, which could lead to plastic deformation or fatigue fracture. The second spring 432 is usually a compression spring, installed between the bottom of the connecting part 412 and the bottom wall of the mounting cavity 122, or sleeved on the guide post of the connecting part 412. The presence of the second spring 432 ensures that after each unlocking operation, the system can quickly return to the standby state, ready for the next installation or unlocking. Efficient reset means that when the user releases their hand, the unlocking part 411 can immediately spring up, and the driving part 413 will then disengage from the driving surface 4221 of the latch 420, releasing the constraint on the latch 420, allowing the first spring 431 to push the latch 421 to the locking position without obstruction.

[0087] The present invention also provides a cleaning base station 1 for a lawnmower, which includes a cleaning chamber 20 and a cleaning device 10 as described in any of the above embodiments; the cleaning chamber 20 is provided with a receiving cavity 201 for accommodating the lawnmower; the cleaning device 10 is disposed in the receiving cavity 201 and is used to support the lawnmower and clean the moving wheels of the lawnmower.

[0088] It is understood that in the cleaning base station 1 of this embodiment, by setting the cleaning device 10 in any of the above embodiments, not only is efficient cleaning of the lawnmower achieved, but also the unique quick-release structure of the cleaning device 10 makes the maintenance of the base station exceptionally convenient. When the bristles on the cleaning device 10 wear out, accumulate too much dirt requiring deep cleaning, or the internal mechanical structure needs maintenance, the user does not need to use any tools; they can simply operate the unlocking piece 410 to remove the heavy cleaning module entirely from the cleaning chamber 20. This modular design greatly reduces the user's maintenance threshold and time cost.

[0089] Furthermore, the cleaning base station 1 also includes a cleaning component 30, which is disposed in the receiving cavity 201 and is connected to an external water supply line for spraying water to clean the lawnmower. The cleaning chamber 20 is also provided with a drainage structure, which is connected to the receiving cavity 201 and is used to discharge sewage.

[0090] In some embodiments, the cleaning component 30 can be a multi-angle high-pressure nozzle array that sprays water onto key areas of the lawnmower, such as the chassis, wheel assembly sides, and sensor windows. The nozzle's spray angle, water pressure, and pulse frequency are all adjustable to meet cleaning needs with varying degrees of dirt.

[0091] Specifically, the drainage structure includes, but is not limited to, drain holes and drainage channels. Drain holes are used to discharge wastewater, and their location is typically at the lowest point of the receiving chamber 201. Gravity is used to ensure complete drainage, preventing water accumulation, bacterial growth, and odor. Drain channels collect wastewater from the cleaning chamber 20 for unified discharge or recycling. The drainage channels should be designed with a slope to guide water flow quickly towards the drain holes, preventing wastewater stagnation within the chamber. Furthermore, the drainage structure can integrate solid-liquid separation devices (such as filter baskets) to intercept large pieces of grass clippings, leaves, and other solid waste washed down, preventing them from entering downstream pipes and causing blockages. For scenarios with high environmental protection requirements, the drainage outlet can also be connected to a wastewater recycling system, where water is recycled for subsequent cleaning or greening irrigation after sedimentation and filtration.

[0092] Specifically, the cleaning chamber 20 has a snap-fit ​​hole 202; the cleaning device 10 also includes a disassembly and assembly component 400, which includes an unlocking component 410, a locking component 221 and a resetting component. The unlocking component 410 is tractively connected to the locking component 221, and the resetting component is used to drive the locking component 221 to reset. The locking component 221 is used to snap-fit ​​and fix with the snap-fit ​​hole 202, and the unlocking component 410 is used to drive the locking component 221 to separate from the cleaning chamber 20.

[0093] The locking element 221 here is the specific embodiment of the snap-fit ​​element 420 mentioned above in the base station application scenario, while the snap-fit ​​hole 202 is a corresponding mating structure set on the wall of the cleaning chamber 20. This mating method provides extremely high positioning accuracy and connection strength. When the cleaning device 10 is pushed into place, the locking element 221 automatically springs into the snap-fit ​​hole 202 under the action of the reset element, giving a clear locking feedback. This connection method can not only withstand the static weight of the lawnmower when it is parked, but also resist the reaction force generated by the high-pressure water flow during the cleaning process and the dynamic load caused by the vibration of the lawnmower itself, ensuring the connection of the cleaning device 10 during operation.

[0094] Furthermore, the cleaning chamber 20 is also provided with a receiving groove 2021 that communicates with the snap-fit ​​hole 202, and the cleaning device 10 is housed in the receiving groove 2021.

[0095] The placement of the receiving slot 2021 provides precise installation guidance for the cleaning device 10. Users simply align the cleaning device 10 with the slot and push it in; alignment is automatic, eliminating the need for repeated angle adjustments. Secondly, after embedding the cleaning device 10 into the receiving slot 2021, its top surface can be flush with or smoothly transition to the inner wall of the cleaning chamber 20, making the internal space of the receiving cavity 201 more regular. This avoids interference from protruding structures on the lawnmower's entry and exit, reduces hard-to-clean areas, and facilitates daily cleaning of residual dirt inside the base station. The receiving slot 2021 allows the cleaning device 10 to be housed, facilitating its assembly and ensuring a flat wall surface. This flat wall design is crucial for the lawnmower's automatic recharging, ensuring that the lawnmower will not lose its way or be damaged by colliding with protruding parts during visual navigation or edge-keeping. Furthermore, the concealed installation structure enhances the overall aesthetics of the base station, making the internal components appear neater and more organized.
