DETAILED DESCRIPTION

[0071] The following embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0072] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" can be a connection between each other and the relative position relationship after connection remains unchanged. "Rotational connection" can be a connection between each other and can rotate relative to each other after connection. The term "integrated molding" means that in the process of forming one of a plurality of components, the component is connected to the other components without the need for further processing (such as bonding, welding, snap connection, screw connection) to connect the two components together. The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", "side", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0073] Please refer to Figure 1, which is a schematic diagram of the structure of a grass collecting device 1000 provided in a first embodiment of the present application. The grass collecting device 1000 includes a grass collecting frame 100, a grass collecting box 200, and a swing module 300. The swing module 300 is rotatably mounted on the grass collecting frame 100. The grass collecting box 200 is rotatably connected to the rear end of the grass collecting frame 100 via the swing module 300. The swing module 300 is used to drive the grass collecting box 200 to swing relative to the grass collecting frame 100, thereby realizing the automatic grass unloading function of the grass collecting device 1000 and improving grass unloading efficiency.

[0074] It should be noted that the purpose of Figure 1 is only to schematically illustrate the connection method between the grass collecting bracket 100, the swing module 300 and the grass collecting box 200, and does not specifically limit the connection position, connection relationship and specific structure of each component. Figure 1 is only an illustration of the structure of the grass collecting device 1000 in the embodiment of the present application, and does not constitute a specific limitation of the grass collecting device 1000. In other embodiments of the present application, the grass collecting device 1000 may include more or fewer components than shown in Figure 1, or combine certain components, or different components. For example, the grass collecting device 1000 may also include but is not limited to a roller brush mechanism, a connecting mechanism, etc. The connecting mechanism is used to connect the grass collecting device 1000 to the lawn mower. The roller brush mechanism can be used to collect grass cut by the lawn mower.

[0075] For accuracy, all references to directions in this document should be made to Figure 1. The term "length direction X" refers to the arrangement of the grass collection stand 100 and grass collection box 200, i.e., the front-to-back direction (where the positive direction of the X axis is forward). The term "width direction Y" refers to the arrangement of the two pivoting arms 220 in the grass collection box 200, i.e., the left-to-right direction (where the positive direction of the Y axis is right). The term "height direction Z" refers to the arrangement of the support body 110 and mounting protrusion 120 in the grass collection stand 100, i.e., the up-to-down direction (where the positive direction of the Z axis is upward). The length direction X, width direction Y, and height direction Z collectively constitute the three orthogonal directions of the grass collection box 200. For ease of description, the up-to-down, left-to-right, and front-to-back directions in this application are relative and do not constitute limitations. The length direction X, width direction Y, and height direction Z of the grass collection box 200 can be customized based on the specific product structure and the perspective of the accompanying drawings, and are not specifically limited in this application. For clarity, the ends of the grass collector 1000 along its length (X) are defined as the head and tail, respectively, with the head and tail positioned opposite each other. In Figure 1 , when describing the front or back of an object, the left end is the head, and the right end is the tail. For example, the tail of the grass collector 100 refers to the rear end of the grass collector 100, closer to the grass collection box 200. The head of the grass collector 100 refers to the front end of the grass collector 100, farther from the grass collection box 200.

[0076] The grass collector 1000 has two modes: a collecting state and a discharging state. In the collecting state, the grass collector 200 covers the grass collector frame 100 and temporarily stores grass clippings cut by the mowing device. In the discharging state, the grass collector 200 flips relative to the grass collector frame 100 to dump the collected grass clippings. A swing module 300 is mounted on the top of the grass collector frame 100 and is used to tilt the grass collector 200 to dump the collected grass clippings, thereby enabling the grass collector 1000 to automatically discharging grass clippings and improving discharging efficiency. In this embodiment, the swing module 300 is mounted on the mounting protrusion 120 and located at the rear of the grass collector frame 100. This not only facilitates the alignment of the swing module 300 with the grass collector frame 200, improving the tilting performance of the swing module 300, but also increases the height of the pivot point, thereby improving discharging efficiency.

[0077] Please refer to Figures 1 and 2 together. Figure 2 is a partial cross-sectional view of the grass collecting bracket 100 of the grass collecting device 1000 in Figure 1. An embodiment of the present application provides a grass collecting bracket 100. The grass collecting bracket 100 is used to connect a lawn mower and a grass collecting box 200. The grass collecting bracket 100 includes a bracket body 110 and a mounting protrusion 120. The bracket body 110 is fixed to the lawn mower. The mounting protrusion 120 is protruding from the top of the bracket body 110 and is located at the rear of the bracket body 110. A swing module 300 is disposed within the mounting protrusion 120 for mounting thereon, which drives the grass collecting box 200 to swing relative to the grass collecting bracket 100.

[0078] The grass collecting bracket 100 provided in the embodiment of the present application, on the one hand, the mounting protrusion 120 can be used to adjust the installation height of the swing module 300, thereby avoiding waste of the assembly space of the grass collecting bracket 100, making the structural distribution reasonable and compact, and increasing the height of the rotation point, thereby improving the grass unloading efficiency; on the other hand, the swing module 300 is arranged on the top of the grass collecting bracket 100, which reduces the swing area of ​​the swing module 300 relative to the grass collecting bracket 100, reduces the occupied volume of the swing module 300, and improves space utilization.

[0079] In one possible implementation, the mounting protrusion 120 defines a mounting cavity 1201 for accommodating the swing module 300. A mounting hole 1101, communicating with the mounting cavity 1201, is provided on the side of the bracket body 110 facing away from the mounting protrusion 120. Thus, the provision of the mounting hole 1101 at the bottom of the bracket body 110 enhances the waterproof performance of the mounting protrusion 120, prolongs the service life of the swing module 300, facilitates assembly of the swing module 300, and enhances the appearance of the grass collector 100.

[0080] In one possible implementation, the grass collector stand 100 further includes a cover plate 130 that covers the mounting hole 1101. This prevents grass or other debris from entering the mounting cavity 1201, making cleaning the grass collector stand 100 easier. Furthermore, the cover plate 130 provides support or a mounting location for the swing module 300, thereby improving the reliability and strength of the connection between the swing module 300 and the grass collector stand 100. The cover plate 130 is detachably connected to the stand body 110, facilitating installation and maintenance and replacement of the swing module 300. The detachable connection between the cover plate 130 and the stand body 110 can be achieved through, but is not limited to, mounting structures or snap fasteners. In another possible embodiment, the cover plate 130 and the stand body 110 can be non-detachably connected through gluing or welding, thereby enhancing the connection strength and assembly efficiency of the grass collector stand 100.

[0081] In another possible implementation, when the swing module 300 is installed in the mounting cavity 1201 through the mounting hole 1101, the shell of the swing module 300 can cover the mounting hole 1101, thereby preventing grass or other debris from entering the mounting cavity 1201, reducing the difficulty of cleaning the grass collecting bracket 100.

[0082] The grass collector 200 includes a main body 210 and pivoting arms 220 mounted on the main body 210. The pivoting arms 220 are located on either side of the main body 210 in the width direction Y of the grass collector stand 100. When a user applies force to the handle 230, the force is evenly distributed across the two pivoting arms 220, preventing stress concentration. This extends the lifespan of the grass collector 200 and improves ease of use and operation. Furthermore, the top space of the main body 210 is effectively utilized, improving space efficiency.

[0083] In one possible implementation, the grass collector 200 may further include a handle 230. The handle 230 is disposed on the box body 210 and is located near the rotating arm 220. The handle 230 is used to drive the box body 210 to flip relative to the grass collector bracket 100, thereby rationally utilizing the top space of the box body 210 and improving space utilization. It also enables the grass collector 200 to have both manual and automatic grass unloading functions, enriching the use scenarios of the grass collector 200 and improving the user experience.

[0084] Please refer to Figures 2 and 3 . Figure 3 is a side view of the grass collecting bracket 100 of the grass collecting device 1000 in Figure 1 . Along the width direction Y of the grass collecting bracket 100, the end of the mounting boss 120 facing away from the bracket body 110 defines an axial hole 1202 that communicates with the mounting cavity 1201. Both ends of the swing module 300 extend through and extend from the axial hole 1202. This facilitates assembly of the swing module 300 with the grass collecting box 200 while also ensuring the integrity of the mounting boss 120, enhancing its overall structural strength and improving the reliability of the connection between the swing module 300 and the mounting boss 120.

[0085] For example, in this embodiment, the shaft hole 1202 is located on the side of the mounting boss 120 facing away from the bracket body 110. This further increases the installation height of the swing module 300, improves the space utilization of the mounting cavity 1201 of the mounting boss 120, and provides a reasonable and compact structure. It also raises the height of the pivot point, improving grass unloading efficiency, and provides sufficient space for the swing module 300 and grass collection box 200 to rotate. In another possible implementation, the shaft hole 1202 is located in the middle of the mounting boss 120 or at another location, which is not specifically limited in this application.

[0086] Along the height direction Z of the grass collector stand 100, the highest point of the mounting protrusion 120 is higher than the highest point of the stand body 110. This provides more space for the swing module 300 to assemble, while ensuring the pivot point is at a high enough level, improving grass unloading efficiency and space utilization. For example, in this embodiment, the mounting protrusion 120 is positioned so as to protrude relative to the stand body 110 in the height direction Z of the grass collector stand 100. The mounting protrusion 120 is integrally formed with the stand body 110, thereby enhancing the overall structural strength of the grass collector stand 100. In one possible implementation, the mounting protrusion 120 and the stand body 110 may also be fixedly connected via a mounting structure.

[0087] The bracket body 110 comprises a first frame 111a and a second frame 112a connected to the first frame 111a. The second frame 112a protrudes from the rear of the first frame 111a in the longitudinal direction X of the grass collector bracket 100 and is suspended from the bottom of the first frame 111a in the height direction Z of the grass collector bracket 100. A mounting protrusion 120 is provided on the second frame 112a, facilitating installation of the swing module 300 from the bottom of the second frame 112a into the mounting cavity 1201 of the mounting protrusion 120, thereby improving assembly efficiency between the swing module 300 and the grass collector bracket 100. Along the width direction Y of the grass collector bracket 100, the width of the first frame 111a is greater than that of the second frame 112a, facilitating the positioning and assembly of the grass collector bracket 100 and the grass collection box 200.

[0088] For example, in this embodiment, the top surface of the mounting protrusion 120, facing away from the bracket body 110, is configured as a curved surface 1205. This allows rainwater to drain quickly from the grass collector 100 along the curved surface 1205 of the mounting protrusion 120. Furthermore, it improves the aesthetics of the grass collector 100 and avoids the risk of collisions and installation difficulties caused by the irregular outer wall of the mounting protrusion 120. In one possible implementation, the top surface of the mounting protrusion 120, facing away from the bracket body 110, can also be flat.

[0089] In one possible implementation, a detector 500 is provided on the side wall of the mounting protrusion 120 facing the grass collection box 200. The detector 500 is used to detect the grass collection status in the grass collection box 200, so that the user can determine whether to unload the grass and determine the swing parameters of the swing module 300 based on the grass collection status. This prevents the grass collection box 200 from collecting too much grass and damaging it, and improves grass unloading efficiency.

[0090] The detector 500 includes but is not limited to at least one of an ultrasonic sensor, an infrared sensor, a laser sensor, a radar sensor, and a visual sensor. For example, in this embodiment, the detector 500 is configured as an ultrasonic sensor to improve detection sensitivity and detection accuracy.

[0091] In one possible implementation, the detector 500 includes a guide surface 501 facing the top of the grass collection box 200. The guide surface 501 is tilted relative to the longitudinal direction X of the grass collection bracket 100, toward the direction away from the mounting protrusion 120. For example, in this embodiment, the detector 500 includes a mounting base 510 and a detection module 520 disposed within the mounting base 510. The mounting base 510 includes a guide surface 501 facing the top of the grass collection box 200. The guide surface 501 extends downwardly relative to the mounting protrusion 120. This prevents interference between the grass collection box 200 and the grass collection bracket 100 of the grass collection device 1000 when the grass collection box 200 rotates relative to the grass collection bracket 100. Furthermore, the sensing range of the detector 500 within the grass collection box 200 is increased, improving detection precision and accuracy. Furthermore, water accumulated on the detector 500 can be promptly drained away, enhancing the detector's waterproof performance.

[0092] For example, in this embodiment, the detection module 520 is detachably mounted on the grass collector 100 via a mounting base 510, thereby facilitating maintenance, replacement, and cleaning of the detector 500. In one possible implementation, the mounting base 510 is integrally formed with the grass collector 100. The detection module 520 is detachably mounted within the mounting base 510.

[0093] The sidewall of the mounting protrusion 120 is provided with a wiring hole 1203 that communicates with the inner cavity of the fixing base 510, thereby connecting the detection module 520 to the swing module 300, shortening the connection line and achieving a compact structure. The fixing base 510 and the mounting protrusion 120 are sealed together to prevent damage to the detection module 520. In one possible implementation, the fixing base 510 and the mounting protrusion 120 are sealed together by a sealing member 530. The detection module 520 may include, but is not limited to, a camera and a circuit board. The circuit board is capable of processing image data collected by the camera.

[0094] In one possible implementation, the grass collector stand 100 further includes a handle 60. One end of the handle 60 is fixed to the mounting protrusion 120, and the other end is fixed to the stand body 110. This facilitates quick and easy movement and transport of the grass collector stand 100. Furthermore, securing one end of the handle 60 to the mounting protrusion 120 creates a compact structure and raises the height of the handle 230, positioning the center of gravity of the grass collector stand 100 below it. This enhances safety, reduces effort, and provides greater comfort.

[0095] In a possible implementation, both ends of the handle 60 may be fixed to the bracket body 110. The connection configuration of the handle 60 may be designed based on factors such as the center of gravity of the grass collecting bracket 100, and is not specifically limited in this application.

[0096] Please refer to Figures 2, 4, and 5. Figure 4 is a front view of the grass collecting bracket 100 of the grass collecting device 1000 in Figure 1. Figure 5 is a schematic diagram of the assembly structure of the bracket body 110 and handle 60 of the grass collecting bracket 100 in Figure 4. In one possible implementation, a positioning structure 31a is provided on the bracket body 110 and / or the mounting protrusion 120, and a guide structure 61 is provided on the handle 60 to cooperate with the positioning structure 31a. This arrangement not only facilitates assembly positioning of the handle 60, but also facilitates positioning the handle 60 in the middle of the grass collecting bracket 100, ensuring that the center of gravity of the grass collecting bracket 100 passes through the handle 60. This arrangement offers advantages such as a simple structure, a rational layout, and convenient handling. For example, in this embodiment, the positioning structure 31a is provided on both the bracket body 110 and the mounting protrusion 120. In another possible implementation, a guide structure 61 is provided on each end of the handle 60. One of the guide structures 61 cooperates with the positioning structure 31 a provided on the bracket body 110 , and the other guide structure 61 cooperates with the positioning structure 31 a provided on the mounting protrusion 120 , thereby facilitating the installation and positioning of the handle 60 .

[0097] The positioning structure 31a includes a positioning post 311 and / or a positioning hole 312. The guide structure 61 is configured as a connecting rod inserted into the positioning post 311 and / or the positioning hole 312. The positioning post 311 is locked to the connecting rod via a locking structure 70. For example, in this embodiment, the positioning post 311 is provided on the bracket body 110. This positioning post 311 can support the handle 60 and raise the height of the handle 60 so that the center of gravity of the grass collecting bracket 100 is located below the handle 230, enhancing safety, saving effort, and providing comfort. The positioning post 311 has an axial through-hole with a limit step provided within the through-hole. The connecting rod stops against the limit step. The locking structure 70 passes through the through-hole and locks to the connecting rod. The locking structure 70 stops against the limit step, thereby achieving a fixed connection between the handle 60 and the bracket body 110.

[0098] The mounting protrusion 120 is provided with a positioning hole 312, and a limiting step is also provided in the positioning hole 312, and the connecting rod is stopped by the limiting step. The locking structure 70 passes through the positioning hole 312 and is locked to the connecting rod, and the locking structure 70 is stopped by the limiting step, thereby realizing a fixed connection between the handle 60 and the bracket body 110. In the embodiment of the present application, the mounting protrusion 120 raises the handle 60, thereby simplifying the structure of the positioning column 311 supporting the handle 60, with a reasonable layout and a compact structure. The number of positioning structures 31a and the number of guide structures 61 can both include one or more. For example, in this embodiment, the number of positioning structures 31a and the number of guide structures 61 correspond one to one, and include a plurality of them, thereby improving the positioning and assembly effect.

[0099] In some possible implementations, a limiting groove 320a is provided on the mounting protrusion 120. One end of the handle 60 is inserted into the limiting groove 320a, and a positioning structure 31a is provided in the limiting groove 320a. The limiting groove 320a enables pre-assembly of the handle 60 and the mounting protrusion 120, thereby facilitating operation and improving assembly efficiency of the handle 60 and the mounting protrusion 120.

[0100] Referring again to Figures 1 and 5 , in some possible implementations, the grass collector stand 100 further includes a top cover 150. The top cover 150 is positioned on top of the stand body 110. The mounting protrusion 120 and the handle 60 extend through the top cover 150, thereby enhancing the aesthetics and waterproofing of the grass collector stand 100. A housing space 102 is formed between the top cover 150 and the stand body 110. The positioning structure 31a is disposed within the housing space 102. Other structural elements may also be disposed within the housing space 102, but are not specifically limited in this application. The top cover 150 and the stand body 110 can be detachably connected by, but not limited to, mounting structures, snap fasteners, or other means, thereby facilitating assembly of the grass collector stand 100. In one possible embodiment, the top cover 150 and the stand body 110 can be non-detachably connected by gluing or welding, thereby enhancing the connection strength between the top cover 150 and the stand body 110 and improving assembly efficiency of the grass collector stand 100.

[0101] In some possible implementations, the grass collector stand 100 further includes two mounting arms 170, disposed on either side of the stand body 110 in the width direction Y of the grass collector stand 100. These mounting arms 170 are used to mount the floating mechanism 400. This, on the one hand, balances the center of gravity of the grass collector 1000 and prevents the risk of tilting. In some embodiments, the mounting arms 170 can also be used to mount other structures, such as, but not limited to, a roller brush mechanism, which is not specifically limited in this application.

[0102] In some possible implementations, the bracket body 110 is provided with an installation space 103 on the side facing away from the installation protrusion 120, and the installation space 103 is used to install a lawn mower, so that after the grass collecting device 1000 is used with the lawn mower, the length of the lawn mower in the length direction X is shortened, making the overall structure of the lawn mowing equipment more compact and improving space utilization.

[0103] Please refer to Figure 6, which is a schematic diagram of the structure of a grass collecting device 1000 provided in a second embodiment of the present application. In the second embodiment, the structure of the grass collecting device 1000 is similar to that of the first embodiment. The differences are that the structure and installation method of the handle 60 of the second embodiment differ from those of the first embodiment, and the structure of the top cover 150 of the second embodiment differs from that of the first embodiment. The remaining structures of the grass collecting device 1000 of the second embodiment refer to those of the first embodiment and are not further described here.

[0104] In the second embodiment, a stopper protrusion 32a is provided on the side of the mounting protrusion 120 facing the handle 60. This stopper protrusion 32a is provided with a stopper groove 320a. One end of the handle 60 is inserted into the stopper groove 320a and stops against the stopper protrusion 32a in the height direction Z of the grass collecting stand 100. Thus, the design of the stopper protrusion 32a not only enhances the connection strength and reliability between the handle 230 and the mounting protrusion 120 but also improves the assembly efficiency of the handle 60 and the stand body 110.

[0105] The top cover 150 is equipped with a plurality of spaced-apart ribs 151. A diversion groove 152 is formed between adjacent ribs 151. This allows rainwater to drain quickly away from the grass collector 100 along the extension of the diversion groove 152, preventing water accumulation within the grass collector 100. Furthermore, the ribs 151 enhance the structural strength of the top cover 150.

[0106] Referring again to Figure 1 , the present embodiment provides a grass collector 200 comprising a housing 210 and a handle 230. A pivoting arm 220 protrudes from the top of the housing 210. The pivoting arm 220 is rotatably connected to the swing module 300 of the grass collector 1000. Driven by the swing module 300, the pivoting arm 220, along with the housing 210, pivots relative to the grass collector frame 100 of the grass collector 1000. A handle 230 is disposed on the housing 210, adjacent to the pivoting arm 220, and is used to pivot the housing 210 relative to the grass collector frame 100.

[0107] The grass collecting box 200 provided in the embodiment of the present application, on the one hand, is based on a rotating arm 220 protruding from the top of the box body 210, thereby increasing the height of the rotating point and improving the grass unloading efficiency; on the other hand, based on the fact that the grass collecting box 200 is provided with a handle 230 and the rotating arm 220 rotatably connected to the swing module 300 of the grass collecting device 1000, the handle 230 is arranged close to the rotating arm 220, thereby rationally utilizing the top space of the box body 210, improving space utilization, and realizing that the grass collecting box 200 has manual and automatic grass unloading functions, enriching the use scenarios of the grass collecting box 200 and improving user experience.

[0108] In one possible implementation, a semi-open groove 2201 is provided on the side of the rotating arm 220 facing the housing body 210 in the height direction Z of the grass collector 200, which mates with the swing module 300, thereby facilitating a detachable connection between the grass collector 200 and the swing module 300. The opening of the semi-open groove 2201 faces the housing body 210. As can be appreciated, when a user needs to lift the grass collector 200 upward, they can grasp the handle 230 to tilt the grass collector 200 relative to the grass collector support 100 to a certain angle, then push forward toward the swing module 300 to disengage the semi-open groove 2201 of the rotating arm 220 from the swing module 300, thereby quickly removing the grass collector 200 from the grass collector support 100 and allowing the grass collector 200 to be lifted upward. The semi-open groove 2201 is configured as a special-shaped groove, so that the swing of the swing module 300 can drive the rotating arm 220 and the box body 210 to swing synchronously, thereby realizing the overall flipping movement of the grass collecting box 200 relative to the grass collecting bracket 100.

[0109] For example, in this embodiment, the pivoting arms 220 are located on either side of the box body 210 in the width direction Y of the grass collection box 200, with the handle 230 positioned between the two pivoting arms 220. This allows for even force distribution between the two pivoting arms 220 when a user applies force to the handles 230, thereby preventing stress concentration and extending the lifespan of the grass collection box 200 and enhancing ease of use and operation. Furthermore, this effectively utilizes the space above the box body 210, improving space efficiency. In one possible implementation, the number of pivoting arms 220 may include one, three, or more, though this is not a specific limitation. The handle 230 is positioned in the center of the box body 210 to prevent deformation or damage caused by the center of gravity of the grass collection box 200 not being aligned with the direction of force applied by the handles 230. This further enhances the design, aesthetics, and usability of the handle 230. In one possible implementation, the handle 230 is aligned with the two rotating arms 220 in the width direction Y of the grass collecting box 200. It should be noted that the arrangement of the handle 230 can be designed according to factors such as the structure and connection position of the rotating arm 220, and this application does not impose any specific limitation.

[0110] The pivoting arm 220 is configured as a hook structure. The swing module 300 is equipped with a hanging rod structure that is rotatably connected to the hook structure, thereby enabling the grass collection box 200 to be flipped relative to the grass collection bracket 100, thereby realizing the grass collection box 200's grass unloading function. In one possible implementation, the grass collection box 200 is detachable from the grass collection bracket 100, facilitating operations such as cleaning, maintenance, and repair of the grass collection box 200, and enriching the use scenarios of the grass collection box 200 and improving its flexibility.

[0111] Please refer to Figures 1 and 7 . Figure 7 is a partial cross-sectional view of the grass collection device 1000 in Figure 1 . A grass collection mechanism is also provided on the housing 210. This mechanism may include, but is not limited to, a driver and a roller brush connected to the driver. The roller brush is used to collect grass clippings into the grass collection box 200 . A grass collection chamber 2101 is provided within the housing 210 . A grass collection port 2102, connected to the grass collection chamber 2101, is located on the side of the housing 210 facing the grass collection bracket 100 to facilitate grass collection. For example, in this embodiment, the box body 210 includes a box body 211, a box cover 212 and a pressure cover 213. The box cover 212 is fixedly connected to the box body 211 to form a grass collecting chamber 2101. The pressure cover 213 is arranged in the grass collecting chamber 2101 and forms an enclosed space 2103 with the box cover 212. The handle 230 includes a gripping portion 231 and a bending portion 233. The gripping portion 231 is located outside the grass collecting chamber 2101, and the bending portion 233 is bent relative to the gripping portion 231 and is arranged in the enclosed space 2103. Therefore, on the one hand, based on the handle 230 provided on the box cover 212, it is convenient for the user to hold and operate the grass collection box 200, and it is flexible and convenient to use; on the other hand, the bent portion 233 of the handle 230 is provided in the enclosed space 2103 formed by the pressure cover 213 and the box cover 212, thereby avoiding grass clippings from remaining at the connection between the bent portion 233 and the inner wall of the grass collection chamber 2101, thereby reducing the difficulty of cleaning the grass collection box 200.

[0112] For example, in this embodiment, the box body 211 and the box cover 212 are detachably connected, thereby facilitating installation, maintenance, and cleaning of the handle 230 and the pressure cover 213. The box body 211 and the box cover 212 can be detachably connected using, but not limited to, mounting structures, snap fasteners, and other methods. In one possible embodiment, the box body 211 and the box cover 212 are non-detachably connected, thereby improving the connection strength between the box body 211 and the box cover 212 and enhancing the assembly efficiency of the grass collection box 200.

[0113] Please refer to Figures 7 and 8. Figure 8 is an enlarged view of section I in Figure 7. The bent portion 233 is sandwiched between the pressure cover 213 and the box cover 212, thereby simplifying the fixed connection between the handle 230 and the box body 210 and preventing the handle 230 from rotating, thereby improving the user experience. The pressure cover 213 and the box cover 212 are fixedly connected together by a locking member, thereby sandwiching the bent portion 233 of the handle 230 between the pressure cover 213 and the box cover 212 and facilitating the installation of the pressure cover 213. In one possible implementation, the bent portion 233 of the handle 230 can be fixed between the pressure cover 213 and / or the box cover 212 by a locking structure to improve the connection strength between the handle 230 and the box body 210.

[0114] In one possible implementation, the pressure cover 213 and / or the box lid 212 are provided with a position-limiting constraint structure 215. The bent portion 233 is constrained within the enclosed space 2103 by the position-limiting constraint structure 215, thereby facilitating the assembly and positioning of the handle 230 and improving assembly efficiency. For example, in this embodiment, the position-limiting constraint structure 215 is configured as a position-limiting hole that matches the shape of the bent portion 233. For example, the pressure cover 213 is provided with a first position-limiting portion 2151, and the box lid 212 is provided with a second position-limiting portion 2152. The first position-limiting portion 2151 corresponds to the second position-limiting portion 2152 and forms a position-limiting hole that matches the shape of the bent portion 233, thereby limiting the position of the bent portion 233. The position-limiting hole is circular. In one possible implementation, the position-limiting hole can also be a regular or irregular hole, such as an elliptical hole, a square hole, or a polygonal hole. The number of position-limiting constraint structures 215 can include one or more, and this application does not impose any specific restrictions.

[0115] Please refer to Figures 8 and 9 . Figure 9 is a bottom view of the cover 212 and handle 230 of the grass collection box 200 of the grass collection device 1000 in Figure 1 . In one possible implementation, the pressing cover 213 and / or the cover 212 are provided with reinforcing ribs 216 to enhance the overall structural strength of the pressing cover 213 and / or the cover 212 and extend the service life of the grass collection box 200. In this embodiment, both the pressing cover 213 and the cover 212 are provided with reinforcing ribs 216. For example, in this embodiment, both the pressing cover 213 and the box body 211 are provided with reinforcing ribs 216.

[0116] In one possible implementation, the lid 212 is provided with reinforcing ribs 216 in the area corresponding to the pressure cover 213 and / or in the area corresponding to the pivot arm 220. This, on the one hand, increases the structural strength of the connection between the pivot arm 220 and the case body 210, preventing deformation or breakage of the pivot arm 220; and on the other hand, increases the structural strength of the lid 212 and the pressure cover 213, preventing deformation or breakage of the lid 212 when a user applies force to the handle 230.

[0117] In one possible implementation, the box cover 212 includes a first region 2121 corresponding to the pressing cover 213 and a second region 2122 connected to the edge of the first region 2121. Reinforcing ribs 216 are provided in the first region 2121. The width of the first region 2121 along the width direction Y of the grass collection box 200 is greater than the distance between the two rotating arms 220. Since the second region 2122 is not provided with reinforcing ribs 216, the probability of grass clippings adhering to the second region 2122 of the grass collection box 200 is reduced. The length of the pressing cover 213 along the longitudinal direction X of the grass collection box 200 is shorter than the length of the pressing cover 213 along the longitudinal direction X of the grass collection box 200, thereby reducing production costs. The distance between the two rotating arms 220 refers to the gap formed by the two rotating arms 220 along the width direction Y of the grass collection box 200.

[0118] In one possible implementation, the limiting ribs include a first rib 2161 and a second rib 2162. The first ribs 2161 are provided on both sides of the first region 2121 along the width direction Y of the grass collection box 200, and the second ribs 2162 are provided in the middle of the first region 2121 along the width direction Y of the grass collection box 200. The distribution density of the first ribs 2161 is greater than that of the second ribs 2162, thereby ensuring structural strength at the connection between the rotating arm 220 and the box body 210 while reducing production costs.

[0119] In one possible implementation, the height of the reinforcing ribs 216 provided on the box cover 212 in the height direction Z of the grass collecting box 200 gradually decreases from the grass collecting box 200 toward the grass collecting bracket 100, thereby reducing the stress concentration at the end of the bent portion 233 facing away from the gripping portion 231, reducing the probability of damage to the box body 210 by the handle 230, and extending the service life of the grass collecting box 200.

[0120] In one possible implementation, the position-limiting and restraining structure 215 is disposed on the reinforcing rib 216, thereby making the overall structure more compact and distributing the force exerted by the handle 230 on the pressure cover 213 or the box lid 212, thereby extending the service life of the grass collection box 200. In another possible implementation, the position-limiting and restraining structure 215 can also be disposed independently of the reinforcing rib 216. For example, the reinforcing rib 216 is provided with a position-limiting hole that mates with the bent portion 233 to form the position-limiting and restraining structure 215. The position-limiting hole can be a closed loop hole or an open loop hole.

[0121] Referring again to Figures 7 and 9, a first clearance groove 2105 is provided on the side of the box body 210 facing the grass collecting device 1000. A pivoting arm 220 extends from the box body 210 toward the swing module 300, with the orthographic projection of the pivoting arm 220 on the box cover 212 positioned within the first clearance groove 2105. This not only increases the pivot point height but also provides more room for the pivoting arm 220 to rotate, improving grass unloading efficiency. It also makes the overall structure more compact, effectively utilizing the space above the box body 210 and improving space efficiency.

[0122] In one possible implementation, the bottom wall of the first relief groove 2105 is recessed inwardly to form a second relief groove 2106 in the box body 210. A bent portion 233 extends through the sidewalls of the second relief groove 2106 and into the enclosed space 2103. This prevents interference with the handle 230 when the grass collection box 200 is flipped relative to the grass collection stand 100. Furthermore, this provides space for the handle 230 to be installed, improving assembly efficiency and effectively utilizing the space above the box body 210.

[0123] For example, in this embodiment, the second relief groove 2106 is trapezoidal. On the one hand, this allows the second relief groove 2106 to better adapt to the corner of the bent portion 233, improving the assembly effect; on the other hand, it prevents the handle 230 from interfering with other components during the rotation of the box body 210.

[0124] Please refer to Figures 7 and 10 together. Figure 10 is an enlarged view of handle 230 in Figure 9. Handle 230 is rod-shaped. For example, in this embodiment, the radial cross-section of handle 230 is circular. Handle 230 can be formed by bending a rod-shaped structure. In one possible implementation, handle 230 can also be formed by braiding a rod-shaped structure; or, alternatively, by bending a plate-shaped or tubular structure, which is not specifically limited in this application.

[0125] In one possible implementation, the bent portion 233 includes a first bent section 2331 and a second bent section 2332. The first bent section 2331 connects the grip portion 231 and the second bent section 2332. The first bent section 2331 is located on one side of the grip portion 231 in the width direction Y of the grass collection box 200, while the second bent section 2332 and the grip portion 231 are located on the same side of the first bent section 2331 in the length direction X of the grass collection box 200. Thus, the bent portion 233 is arranged in a curved path within the enclosed space 2103, thereby improving the connection strength between the handle 230 and the box body 210. Furthermore, by designing the first bent section 2331 and the second bent section 2332 to extend in different directions, the force acting on the handle 230 is dispersed at different locations on the grass collection bracket 100, avoiding stress concentration and extending the service life of the grass collection box 200. In some embodiments, the extension path of the bent portion 233 within the enclosed space 2103 may be, but is not limited to, an L-shape, an S-shape, a Z-shape, or a U-shape. In one possible implementation, the bent portion 233 may further include a third bent section connecting the first bent section 2331 and the second bent section 2332, thereby improving the structural strength of the bent portion 233 and the connection strength between the bent portion 233 and the grass collecting bracket 100.

[0126] In one possible implementation, the grip portion 231 includes a first grip section 2311 and a second grip section 2312 connected between the first grip section 2311 and the bent portion 233. The first grip section 2311 is spaced apart from the box body 210, while the second grip section 2312 is tilted relative to the top wall of the box body 210. This facilitates user operation of the handle 230 and provides clearance for bending the grass collection box 200.

[0127] Referring again to Figures 7 and 8 , in one possible implementation, the grass collecting device 1000 further includes a detector 500. The detector 500 is located on the top of the grass collecting bracket 100 facing the grass collecting box 200, and on the side of the pressure cover 213 facing away from the rotating arm 220. The detector 500 is used to detect the grass collection status within the grass collecting box 200, allowing the user to determine whether to unload the grass based on the collected grass status, thereby preventing damage to the grass collecting box 200 caused by excessive grass collection.

[0128] The detector 500 includes but is not limited to at least one of an ultrasonic sensor, an infrared sensor, a laser sensor, a radar sensor, and a visual sensor. For example, in this embodiment, the detector 500 is configured as an ultrasonic sensor to improve detection sensitivity and detection accuracy.

[0129] Referring to Figures 2 and 7-8 , in one possible implementation, the detector 500 includes a mounting base 510 and a detection module 520. The detection module 520 is disposed within the mounting base 510. The mounting base 510 includes a guide surface 501 facing the pressure cover 213, with the guide surface 501 tilted away from the pressure cover 213. This prevents interference between the grass collection box 200 and the pressure cover 213 when the grass collection box 200 rotates relative to the grass collection bracket 100 of the grass collection device 1000. Furthermore, it increases the sensing range of the detector 500 within the grass collection box 200, improving detection precision and accuracy.

[0130] For example, in this embodiment, the detection module 520 is detachably mounted on the grass collector 100 via a mounting base 510, thereby facilitating maintenance, replacement, and cleaning of the detector 500. In one possible implementation, the mounting base 510 is integrally formed with the grass collector 100. The detection module 520 is detachably mounted within the mounting base 510.

[0131] The present application also provides a lawn mowing device, comprising a lawn mower and the aforementioned grass collection box 200 or the aforementioned grass collection device 1000, wherein the grass collection box 200 or the grass collection device 1000 is connected to the rear end of the lawn mower. The lawn mowing device may include, but is not limited to, walk-behind, ride-on, and fully automatic intelligent lawn mowing devices, and this application does not limit this. The lawn mowing device can move on the ground. For example, the lawn mowing device can move on the ground when pushed by a user. In another example, the lawn mowing device can be inherently mobile and can automatically move on the ground via a drive mechanism.

[0132] The lawn mower includes but is not limited to a frame, a cutting mechanism, and a lifting mechanism. The grass collecting device 1000 or the grass collecting box 200 is arranged at the rear of the frame. For example, the grass collecting bracket 100 is detachably arranged on the frame of the lawn mower, so that the grass collecting device 1000 can be removed from the frame of the lawn mower, which is convenient for maintenance and replacement, and enriches the different application scenarios of the lawn mower, such as mowing scenes, grass collecting scenes, or mowing and collecting scenes. In some embodiments, the grass collecting bracket 100 can also be non-detachably arranged on the frame of the lawn mower, which is not specifically limited in this application. The cutting mechanism and the lifting mechanism are arranged on the frame. The lifting mechanism is used to drive the cutting mechanism to move along the height direction Z of the lawn mower. The cutting mechanism is used to cut grass.

[0133] Please refer to Figures 11, 12, and 13. Figure 11 is a schematic diagram of a partial structure of the grass collecting device 1000 in Figure 1; Figure 12 is a schematic diagram of the structure of the swing module 300 of the grass collecting device 1000 in Figure 11 from a first perspective. An embodiment of the present application provides a swing module 300; and Figure 13 is a partial cross-sectional view of the grass collecting device 1000 in Figure 11 from a first perspective. The swing module 300 is mounted on the top of the grass collecting frame 100. The swing module 300 includes a swing component 310, a driving component 320, and a mounting bracket 330. The mounting bracket 330 defines a receiving chamber 3302 and is fixed to the grass collecting frame 100. The swing component 310 is mounted on the mounting bracket 330 and located outside the receiving chamber 3302. The driving component 320 is disposed within the receiving chamber 3302 and is in transmission connection with the swing component 310. The driving component 320 and the swing component 310 are arranged in the height direction Z of the swing module 300 and are located below the swing component 310 .

[0134] The swing module 300 provided in the present application is based on the fact that a driving component 320 is provided in the accommodating cavity 3302, and a swing component 310 is provided outside the accommodating cavity 3302, and the driving component 320 and the swing component 310 are arranged in the height direction Z of the swing module 300 and are located below the swing component 310. On the one hand, the swing component 310 and the driving component 320 are installed on the mounting bracket 330, so that the mounting bracket 330 can provide more mounting sites and support sites for the swing component 310 and the driving component 320, thereby improving the swing module 300. 00 performs the swinging motion safely and reliably; on the other hand, the mounting bracket 330 can integrate the swing component 310 and the driving component 320 into an integral module with a simple and compact structure, which is convenient for assembly and maintenance, and reduces the space occupied by the swing module 300 on the grass collecting bracket 100, thereby improving space utilization; on the other hand, the swing module 300 is swung on the top of the grass collecting bracket 100, thereby reducing the swinging operation range of the swing module 300 relative to the grass collecting bracket 100, increasing the height of the swing axis of the swing module 300, and improving the swinging efficiency.

[0135] For example, in this embodiment, the mounting bracket 330 includes a first bracket 51 and a second bracket 52 that are fixedly coupled together. The first bracket 51 is fixed to the grass collector bracket 100 and forms a swing chamber 3303 with the grass collector bracket 100. The swing component 310 is positioned within the swing chamber 3303, and the first bracket 51 and the second bracket 52 form a receiving chamber 3302. Thus, the first bracket 51 and the second bracket 52 provide more mounting and support locations for the swing component 310 and the drive component 320, improving the safety and reliability of the swing module 300. Furthermore, the partitioned arrangement of the swing component 310 and the drive component 320 results in a compact design, easy assembly, and improved operational reliability and safety.

[0136] In one possible implementation, the first bracket 51 and the second bracket 52 can be removably fixed to each other by means of snap-fitting, screw locking, etc., thereby facilitating the assembly of the swing component 310 and the driving component 320. In another possible implementation, the first bracket 51 and the second bracket 52 can be non-removably fixed to each other by means of welding, bonding, integral molding, etc., which is not specifically limited in this application.

[0137] For example, in this embodiment, the grass collector stand 100 includes a stand body 110 and a mounting boss 120. The mounting boss 120 is positioned protruding from the top of the stand body 110 and located at the rear end of the stand body 110. A swing module 300 is mounted within the mounting boss 120, which drives the grass collector box 200 to swing relative to the grass collector stand 100. Thus, on the one hand, the mounting boss 120 can be used to adjust the installation height of the swing module 300, thereby avoiding wasted assembly space within the grass collector stand 100, achieving a compact and rational structure, and raising the pivot point height, thereby improving grass unloading efficiency. On the other hand, positioning the swing module 300 at the top of the grass collector stand 100 reduces the swing area of ​​the swing module 300 relative to the inside of the grass collector stand 100, reducing the volume occupied by the swing module 300 and improving space utilization.

[0138] A mounting cavity 1201 for accommodating the swing module 300 is defined within the mounting boss 120. A mounting hole 1101 communicating with the mounting cavity 1201 is defined on the side of the bracket body 110 facing away from the mounting boss 120. Thus, the mounting hole 1101 provided at the bottom of the bracket body 110 creates a seamless connection between the top and side of the mounting boss 120. This allows rainwater and debris to slide down the outer wall of the mounting boss 120 under the action of gravity, reducing the risk of rainwater or debris entering the mounting cavity 1201 through the mounting hole 1101 at the bottom of the bracket body 110. This improves the waterproof and dustproof properties of the mounting boss 120, extends the service life of the swing module 300, facilitates assembly of the swing module 300, and enhances the appearance of the grass collector 100.

[0139] As shown in Figure 13, in one possible implementation, the grass collector 100 further includes a cover plate 130 that covers the mounting hole 1101. This prevents grass or other debris from entering the mounting cavity 1201, making cleaning the grass collector 100 easier. Furthermore, the cover plate 130 provides support or a mounting location for the swing module 300, thereby improving the reliability and strength of the connection between the swing module 300 and the grass collector 100. The cover plate 130 is detachably connected to the bracket body 110, facilitating installation and maintenance and replacement of the swing module 300. The detachable connection between the cover plate 130 and the bracket body 110 can be achieved through, but is not limited to, a locking mechanism or a snap-fit ​​mechanism. In a possible embodiment, the cover plate 130 and the bracket body 110 may be non-detachably connected together by gluing or welding, thereby improving the connection strength between the cover plate 130 and the bracket body 110 and improving the assembly efficiency of the grass collecting bracket 100.

[0140] In another possible implementation, when the swing module 300 is installed in the mounting cavity 1201 through the mounting hole 1101, the swing module 300 can cover the mounting hole 1101, thereby preventing grass or other debris from entering the mounting cavity 1201, reducing the difficulty of cleaning the grass collecting bracket 100, and reducing structural elements, making the overall structure compact and reducing costs.

[0141] The first bracket 51 and the mounting protrusion 120 form a swing cavity 3303 that accommodates the swing component 310. For example, in this embodiment, the first bracket 51 divides the mounting cavity 1201 into two cavities along the height direction Z of the swing module 300. One cavity is the swing cavity 3303 and is used to accommodate the swing component 310, while the other cavity is used to accommodate the driving component 320, the second bracket 52, and a portion of the first bracket 51. This allows for full and reasonable utilization of the space within the mounting cavity 1201, improving space efficiency and making the overall structure more compact.

[0142] The mounting bracket 330 is fixed to the mounting protrusion 120. The mounting bracket 330 and the mounting protrusion 120 are fixedly connected together by a locking structure. The locking structure can be, but is not limited to, a bolt, a snap, etc. For example, in this embodiment, the first bracket 51 is fixed to the mounting protrusion 120. The first bracket 51 and the mounting protrusion 120 can be detachably connected to the mounting protrusion 120 by, but not limited to, a locking structure, a snap, etc., thereby facilitating the assembly and maintenance of the swing assembly and reducing the difficulty of processing. In one possible implementation, the first bracket 51 and the mounting protrusion 120 can also be fixedly connected together in an indestructible manner.

[0143] Referring to Figures 12, 13, and 14, for example, in this embodiment, the first bracket 51 is provided with a movable hole 5101. The swing member 310 includes a swing lever 10 and a transmission tooth 15 disposed on the swing lever 10. The driving member 320 includes a driving member 41 and an output tooth 42 connected to the driving member 41. The output tooth 42 is exposed in the movable hole 5101 and engages with the transmission tooth 15. The driving member 41 drives the output tooth 42 to rotate the transmission tooth 15. Thus, by drivingly connecting the driving member 41 with the output tooth 42 and drivingly engaging the transmission tooth 15 with the output tooth 42, the transmission tooth 15 is fixed to the swing lever 10. This achieves a compact structure and minimizes space. Furthermore, it improves the speed of power transmission while also being able to withstand heavy loads. Furthermore, the output tooth 42 and the transmission tooth 15 are prevented from slipping or impacting during transmission, resulting in excellent stability and reliability. Furthermore, the design of the movable hole 5101 also serves as a positioning mechanism for the assembly of the output tooth 42 and the transmission tooth 15. The hole wall of the movable hole 5101 is spaced apart from the transmission tooth or the output tooth 42 , thereby preventing the transmission tooth or the output tooth 42 from interfering with the mounting bracket 330 during the swinging process of the swing module 300 .

[0144] In one possible implementation, the first bracket 51 does not cover the output teeth 42. For example, the output teeth 42 and the transmission teeth are disposed outside the mounting bracket 330. It should be noted that whether the first bracket 51 defines the movable hole 5101 depends on the position of the transmission teeth and the output teeth 42 relative to the first bracket 51, and this application does not specifically limit this.

[0145] Please refer to Figures 12 and 13 again. The driving member 41 can be but is not limited to a driving motor, a hydraulic driver or a pneumatic driver, etc. The driving component 320 also includes an output shaft 43. The driving member 41 and the output tooth 42 are connected to each other through the output shaft 43. One end of the output tooth 42 is connected to the driving member 41, and the other end is passed through the first bracket 51 and extends out of the accommodating cavity 3302 to connect with the output tooth 42. In this way, the driving member 41 drives the output tooth 42 to rotate, and the output tooth 42 drives the transmission tooth 15 to rotate, thereby realizing that the swing module 300 drives the grass collecting box 200 to swing. The number of output shafts 43 corresponds to the number of output teeth 42, and can include one or two, which is not specifically limited in this application.

[0146] For example, in this embodiment, the radius of the output teeth 42 is smaller than the radius of the transmission teeth 15. This increases the radius of the transmission teeth 15, thereby reducing the rotational speed of the transmission teeth 15 and improving the stability of the swinging motion of the grass collecting box 200 driven by the swinging module 300. Furthermore, this increases the torque that the transmission teeth 15 can withstand, reducing friction between the transmission teeth 15 and the output teeth 42, and improving transmission efficiency. In one possible implementation, the radius of the output teeth 42 may be greater than or equal to the radius of the transmission teeth 15, which is not specifically limited in this application.

[0147] Referring again to Figures 12 and 14 , for example, in this embodiment, the first bracket 51 is further provided with a limiting hole 5102. The swing component 310 also includes a limiting rod 13 disposed on the swing lever 10. The limiting rod 13 is swingably disposed within the limiting hole 5102. Thus, the provision of the limiting rod 13 can limit the swing angle of the swing lever 10, thereby improving the safety and reliability of the swinging motion of the swing module 300.

[0148] In one possible implementation, the first bracket 51 is not provided with the limiting hole 5102. The limiting rod 13 is disposed outside the mounting bracket 330. It should be noted that whether the first bracket 51 has the limiting hole 5102 depends on the position of the limiting rod 13 relative to the first bracket 51, and this application does not specifically limit this.

[0149] The movable hole 5101 and the limiting hole 5102 are disposed at the two ends of the first bracket 51 in the width direction Y of the swing module 300. This makes the combined layout of the swing module 300 reasonable and compact, improves space utilization, and facilitates the processing and forming of the movable hole 5101 and the limiting hole 5102. The movable hole 5101 and the limiting hole 5102 are disposed opposite each other in the width direction Y of the swing module 300.

[0150] For example, in this embodiment, the first bracket 51 extends outward relative to the second bracket 52 in the width direction Y of the swing module 300 to form a first extension portion 511 and a second extension portion 512. The first extension portion 511 is provided with a movable hole 5101, and the second extension portion 512 is provided with a limit hole 5102. This facilitates the alignment and installation of the transmission gear and the limit rod 13, improving assembly efficiency; it also prevents interference between the limit rod 13 and the driver 41 during the swinging process.

[0151] In one possible implementation, the swing arm 10 is overlapped on the first bracket 51. A positioning groove 5103 is provided on the side of the first bracket 51 facing away from the second bracket 52. A positioning protrusion 111 is convexly provided on the swing arm 10, which is movably engaged with the positioning groove 5103. Thus, on the one hand, it is convenient for the alignment assembly of the swing component 310 and the first bracket 51, thereby improving the assembly efficiency; on the other hand, the positioning protrusion 111 is movably engaged with the positioning groove 5103, so that the first bracket 51 can provide support for the swing arm 10, thereby improving the stability and reliability of the swinging motion of the swing module 300 and extending the service life of the swing module 300. In one possible implementation, the swing arm 10 and the first bracket 51 are spaced apart, thereby ensuring the smoothness of the swinging of the swing arm 10 between the relative installations.

[0152] Please refer to Figures 13, 15, and 16. Figure 15 is an enlarged view of the mounting bracket 330 of the swing module 300 in Figure 12 from a second perspective; Figure 16 is an enlarged view of the first bracket 51 of the mounting bracket 330 of the swing module 300 in Figure 12 from a third perspective. In one possible implementation, the first bracket 51 is provided with a limiting structure 515, and the second bracket 52 is provided with a matching structure 521 that cooperates with the limiting structure 515. This facilitates the alignment and assembly of the first bracket 51 and the second bracket 52.

[0153] The first bracket 51 is provided with a fixing plate 516 for securing the driver 41. The fixing plate 516 protrudes from the first bracket 51 toward the second bracket 52 and is provided with a limiting structure 515. Therefore, the fixing plate 516 provided on the first bracket 51 facilitates the installation of the driver 41 and shortens the distance between the output teeth 42 and the transmission teeth 15, thereby improving the compactness of the overall structure of the mounting bracket 330. Furthermore, since the first bracket 51 is fixed to the grass collecting bracket 100, mounting the driver 41 on the first bracket 51 improves the reliability of the connection between the first bracket 51 and the second bracket 52, ensuring the stability and reliability of the connection between the driver 41 and the first bracket 51. In one possible implementation, the driver 41 may also be fixed to the second bracket 52, or alternatively, may be fixed to both the first bracket 51 and the second bracket 52, although this is not specifically limited in this application.

[0154] For example, in this embodiment, the first bracket 51 is provided with a plurality of fixing posts 513 around the edges corresponding to the accommodating cavity 3302, and the second bracket 52 is provided with lugs 522 corresponding to the fixing posts 513. Locking members are inserted through the lugs 522 and locked to the fixing posts 513, thereby achieving a fixed connection between the first bracket 51 and the second bracket. The first bracket 51 is provided with a plurality of connecting structures 514 around the edges, through which the first bracket 51 is fixedly connected to the grass collector 100. It should be noted that the fixing methods of the first bracket 51 and the second bracket 52, and the first bracket 51 and the grass collector 100, can also be used, but are not limited to, snap fasteners, screw fastening, or other methods, and this application does not specifically limit them.

[0155] In one possible implementation, positioning ribs 53 are provided on the first bracket 51 and the second bracket 52 at positions corresponding to the accommodating cavity 3302. The positioning ribs 53 are used to clamp the driver 41 between the first bracket 51 and the second bracket 52, thereby ensuring the reliability and stability of the connection between the driver 41 and the mounting bracket 330 and improving the overall structural strength of the mounting bracket 330.

[0156] Referring again to Figures 11 and 12, the swing module 300 is mounted on the grass collection frame 100 and is used to cause the grass collection box 200 to swing relative to the grass collection frame 100. The swing component 310 includes a swing lever 10 and swing wings 20. The swing lever 10 is provided with swing wings 20 at each end. The swing wings 20 extend radially from the swing lever 10 and are used to mount the grass collection box 200. The drive component 320 is in driving connection with the swing lever 10 and is used to drive the swing lever 10, along with the swing wings 20 and grass collection box 200, to swing synchronously.

[0157] The swing module 300 provided in the embodiment of the present application is based on the swing wings 20 respectively provided at the two ends of the swing rod 10. The swing wings 20 extend along the radial direction of the swing rod 10 and are used to install the grass collecting box 200. The driving component 320 is used to drive the swing rod 10 and swing synchronously with the swing wings 20 and the grass collecting box 200, thereby realizing the intelligent grass unloading function of the grass collecting box 200 and narrowing the operating range of the swing module 300. The structure is simple and compact.

[0158] For example, in this embodiment, the swing wing 20 is provided on the side of the swing rod 10 facing the grass collecting box 200, thereby making the overall structure of the swing module 300 compact, saving materials, and reducing costs. In a possible implementation, the swing wing 20 can also be provided on the circumferential side of the swing rod 10; or, it can also be provided on both sides of the swing rod 10 in the longitudinal direction X of the grass collecting device 1000. The setting position of the swing wing 20 is not specifically limited in this application. The swing wing 20 and the swing rod 10 can be non-detachably connected, for example, the swing wing 20 and the swing rod 10 are integrally formed; or, the swing wing 20 and the swing rod 10 are welded to each other, thereby improving the connection strength and connection reliability of the swing wing 20 and the swing rod 10. The swing wing 20 and the swing rod 10 can also be detachably connected, thereby facilitating installation, disassembly, subsequent replacement and subsequent maintenance, and enriching the use scenarios of the grass collecting box 200 and improving its flexibility of use.

[0159] The grass collecting box 200 is rotatably connected to the rear end of the grass collecting bracket 100. For example, in this embodiment, the grass collecting bracket 100 is detachably connected to the grass collecting box 200 via a swing module 300, facilitating installation, disassembly, subsequent replacement, and maintenance, providing flexibility. The grass collecting box 200 includes a pivoting arm 220. The swinging rod 10 is detachably coupled to the pivoting arm 220. The swinging wing 20 engages and abuts the pivoting arm 220, and is used to drive the grass collecting box 200 to swing about the central axis of the swinging rod 10. This allows the grass collecting box 200 to be detachably connected to the grass collecting bracket 100, facilitating cleaning and maintenance of the grass collecting box 200. Furthermore, the swinging wing 20 engages and abuts the pivoting arm 220, thereby increasing the force-bearing area between the swinging component 310 and the grass collecting box 200, reducing the stress on the pivoting arm 220 and extending the service life of the grass collecting box 200. In a possible implementation, the grass collecting box 200 is non-detachably connected to the grass collecting bracket 100. For example, the swing wing 20 can be non-detachably connected to the rotating arm 220, thereby improving the assembly efficiency between the swing wing 20 and the rotating arm 220.

[0160] For example, in this embodiment, the swing wing 20 and the pivot arm 220 are configured to fit together. This allows, on the one hand, gravity to press the pivot arm 220 against the swing wing 20, securing the pivot arm 220 relative to the swing wing 20. Consequently, when the drive component 320 drives the swing lever 10 to swing, the swing lever 10's rotation drives the swing wing 20 and, together with it, the grass collection box 200 mounted on the swing wing 20, thereby rotating the grass collection box 200 relative to the grass collection support 100. This also facilitates assembly of the pivot arm 220 with the swing lever 10 and the swing wing 20. The swing lever 10 can swing counterclockwise or clockwise relative to the grass collection support 100, opening and closing the grass collection box 200.

[0161] It should be noted that, in the present embodiment, the swing wing 20 and the rotating arm 220 are configured as a special-shaped structure. The so-called special-shaped structure refers to a structure of an irregular shape, such as a protruding structure (i.e., a swing wing 20) is provided on one side of one end of the swing rod 10 along the radial direction of the swing rod 10, resulting in a special-shaped structure at the end. The so-called protruding structure refers to a structure protruding outward from one end of the swing rod 10 along the radial direction of the swing rod 10, such as a bump, a long strip structure, a needle-like structure, a bent structure or other structure, which can be flexibly selected according to the needs of use. The purpose of providing these structures is to enable the rotating arm 220 and the swing wing 20 to be able to realize that the swing wing 20 drives the rotating arm 220 to rotate when they cooperate, and to ensure that the rotating arm 220 and the swing wing 20 have a higher connection reliability.

[0162] In one possible implementation, the swing wing 20 and the pivoting arm 220 can be non-heterogeneous. The swing wing 20 and pivoting arm 220 can be fixedly connected via a fixed structure, allowing the swing lever 10 to rotate the swing wing 20, which in turn rotates the grass collection box 200. The fixed structure is detachably connected to the swing wing 20 and the grass collection box 200, enabling removable assembly of the grass collection box 200. In another possible implementation, the swing wing 20 can be omitted from the swing component 310, for example, with the swing lever 10 directly fixedly connected to the pivoting arm 220.

[0163] Please refer to Figures 11, 12, and 17. Figure 17 is a schematic structural diagram of the swing module 300 in Figure 12 from a second perspective. For example, in this embodiment, the swing wing 20 includes a contoured surface 201 that mates with the pivot arm 220. The contoured surface 201 is smoothly and securely connected to the sidewall of the swing rod 10. This creates a complete outer wall at the junction of the contoured surface 201 of the swing wing 20 and the pivot rod, eliminating the risk of collisions caused by irregular outer walls in cramped and crowded spaces, or otherwise preventing installation difficulties due to irregular outer walls, thereby improving assembly efficiency.

[0164] For example, in this embodiment, the grass collector 200 further includes a housing body 210. A pivoting arm 220 is disposed on the housing body 210. The pivoting arm 220 protrudes from the top of the housing body 210. In the height direction Z of the grass collector 1000, a semi-open groove 2201 is provided on the side of the pivoting arm 220 facing the housing body 210. This semi-open groove 2201 mates with the swinging wing 20 and the swinging lever 10, thereby facilitating the detachable connection between the grass collector 200 and the swinging module 300. The semi-open groove 2201 opens toward the housing body 210. As can be understood, when the user needs to lift the grass collection box 200 upward, the user can tilt the grass collection box 200 relative to the grass collection support 100 to a certain angle and then push it forward toward the swing module 300, so that the semi-open groove 2201 of the rotating arm 220 disengages from the swing rod 10, thereby quickly removing the grass collection box 200 from the grass collection support 100 and lifting the grass collection box 200 upward. The semi-open groove 2201 is configured as a special-shaped groove, and its shape is compatible with the shape of the swing wing 20. Therefore, the swinging of the swing module 300 can drive the rotating arm 220 and the box body 210 to swing synchronously, thereby achieving the overall tilting movement of the grass collection box 200 relative to the grass collection support 100.

[0165] For example, in this embodiment, the profiled surface 201 is configured as a curved surface, thereby reducing the difficulty of machining the swing wing 20 and improving the overall load-bearing capacity of the swing wing 20. In one possible implementation, the profiled surface 201 can also be configured as, but not limited to, a wavy surface, thereby increasing the contact area between the swing wing 20 and the rotating arm 220, reducing the stress on the rotating arm 220, and extending the service life of the grass collection box 200. The profiled surface 201 can also be configured as a flat surface or other shapes, which are not specifically limited in this application.

[0166] For example, in this embodiment, the height of the swing wing 20 along the height direction Z of the swing module 300 gradually decreases from the swing lever 10 toward the swing lever 10. This adapts to the shape of the pivot arm 220, resulting in a compact and rationally designed structure. While reducing the thickness of the swing wing 20, it also ensures a sufficient connection area between the swing wing 20 and the swing lever 10, further strengthening the connection strength between the swing wing 20 and the swing lever 10. The swing wing 20 includes a bearing surface 202 facing away from the pivot arm 220. The bearing surface 202 is substantially parallel to the central axis of the swing lever 10. This prevents the swing lever 10 from squeezing the grass collecting bracket 100 during rotation and facilitates the processing and forming of the swing wing 20.

[0167] The swing wing 20 is spaced apart from the grass collecting frame 100. This provides ample room for the swing arm 220 to swing, preventing interference between the swing module 300 and the grass collecting frame 100 during rotation and improving the smooth rotation of the grass collecting box 200. Furthermore, it facilitates assembly of the swing arm, swing rod 10, and swing wing 20. Furthermore, it raises the pivot point of the swing module 300, improving grass unloading efficiency.

[0168] In one possible implementation, the swing component 310 further includes a reinforcing rib 21. The rib 21 is disposed at the connection between the swing wing 20 and the swing lever 10, and is located on the side of the swing wing 20 closest to the grass collector 100. This enhances the overall structural strength of the swing wing 20, making it less susceptible to deformation or even breakage during use. This ensures the safety and reliability of the swing module 300 in driving the grass collector 200 to swing.

[0169] The swing arm 10 includes a connecting rod 11 and swing arms 12 connected to both ends of the connecting rod 11. Positioning projections 111 are provided on at least one end of the connecting rod 11 and serve to position the transmission gears 15. Each swing arm 12 is provided with a swing wing 20. When the swing module 300 applies a swinging force to the grass collection box 200, the two rotating arms 220 on the box body 210 are evenly distributed, avoiding stress concentration, improving the rotational stability of the grass collection box 200, extending its service life, and making it convenient and easy to use. Furthermore, this effectively utilizes the space above the bracket body 110, improving space efficiency. For example, in this embodiment, the positioning projections 111 protrude radially relative to the connecting rod 11. The transmission gears 15 are positioned between two adjacent positioning projections 111, preventing displacement of the transmission gears 15 along the axial direction of the connecting rod 11 and improving the reliability and stability of the swinging movement of the swing module 300. In a possible implementation, the positioning protrusion 111 may be omitted, for example, the transmission tooth 15 may be directly fixed on the connecting rod 11 .

[0170] In one possible implementation, a transmission tooth 15 is disposed at one end of a connecting rod 11. A limit rod 13 is disposed at the other end of the connecting rod 11, facing away from the transmission tooth 15. Limit rod 13 is used to limit the swing angle of the swing arm 12. This, on the one hand, balances the center of gravity of the grass collecting device 1000, preventing the risk of tilting; on the other hand, it provides a compact and rational structure, improving space utilization and saving costs. Furthermore, the provision of limit rod 13 enhances the safety and reliability of the rotation of the grass collecting box 200.

[0171] The limiting rod 13 extends radially along the swing arm 10, thereby improving structural compactness and reducing manufacturing complexity. The limiting rod 13 and the connecting rod 11 can be integrally formed or independently provided. The limiting rod 13 and the connecting rod 11 can be fixedly connected together using, but not limited to, screwing, clamping, welding, or adhesive bonding.

[0172] In one possible implementation, transmission teeth 15 are disposed at both ends of the connecting rod 11. Each transmission tooth 15 drives the corresponding swing wing 20, which in turn drives the pivot arm 220 to swing, thereby improving swing efficiency and reliability. In another possible implementation, the connecting rod 11 may not be provided with the limit rod 13. In this embodiment, the swing module 300 may further include a sensor configured to detect operating parameters of the drive member 41 or the swing parameters of the swing module 300, thereby ensuring safe and reliable rotation of the grass collection box 200.

[0173] In one possible implementation, the connecting rod 11 is provided with at least one thinning groove 1102. This not only balances the center of gravity of the grass collecting device 1000 but also reduces material usage and production costs. For example, in this embodiment, the connecting rod 11 is provided with multiple thinning grooves 1102, spaced apart along the circumference of the swing arm 10.

[0174] Referring again to Figures 11 and 12 , in one possible implementation, the swing module 300 further includes a sensing component 30 . The sensing component 30 is used to sense the swing angle of the limit rod 13 relative to the mounting bracket 330 . The sensing component 30 senses the rotational position of the limit rod 13 relative to the mounting bracket 330 and generates a sensing signal. This allows the swing module 300 to precisely control the opening angle of the grass collection box 200, preventing transmission failure or backlash in the drive component 320 that could compromise user experience. This also prevents damage to the grass collection box 200, the swing module 300, or the grass collection bracket 100, thereby improving the reliability and safety of the automated flipping of the grass collection box 200.

[0175] Please refer to Figures 11, 17, and 18. Figure 18 is a partial cross-sectional view of the grass collecting device 1000 in Figure 1 from a second perspective, omitting the drive component 320. The limiting rod 13 is located on the side of the connecting rod 11 facing the drive component 320, thereby making the structure of the swing module 300 more rational and compact, improving space utilization. The sensing component 30 also includes a first sensing element 31 and multiple second sensing elements 32. The first sensing element 31 is located at the end of the limiting rod 13 facing away from the swing arm 10. The multiple second sensing elements 32 are fixed relative to the grass collecting frame 100 and are used to sense the first sensing element 31. Thus, by providing the multiple second sensing elements 32 fixed relative to the grass collecting frame 100, the swing module 300 can precisely control the opening angle of the grass collecting box 200.

[0176] In one possible implementation, a fixed structure is provided on the first bracket 51 and / or the second bracket 52. The sensing component 30 also includes a first sensor 31 and a second sensor 32. The first sensor 31 is located at the end of the limiting rod 13 away from the swing arm 10. The second sensor 32 is fixed to the fixed structure. This provides a rational layout for the sensing component 30, achieving a compact swing module 300 and enabling the swing module 300 to precisely control the opening angle of the grass collection box 200.

[0177] In a possible implementation, the swing component 310 , the driving component 320 , the sensing component 30 or other components of the swing module 300 may also be directly mounted on the grass collecting bracket 100 , which is not specifically limited in this application.

[0178] Referring again to Figures 11, 13, and 18, in this embodiment, the sensing component 30 includes, for example, a first sensing element 31 and two second sensing elements 32. The first sensing element 31 is mounted on the limiting rod 13, and the two second sensing elements 32 are mounted on the mounting bracket 330, located on opposite sides of the swing range of the limiting rod 13. The limiting rod 13 can rotate relative to the mounting bracket 330 by a predetermined angle. It should be noted that the predetermined angle refers to the maximum swing angle of the limiting rod 13 relative to the mounting bracket 330, which is equal to the maximum tilt angle of the grass collection box 200 relative to the grass collection bracket 100. When the limiting rod 13 rotates relative to the mounting bracket 330 by the predetermined angle, one of the first sensing element 31 and the second sensing element 32 senses the other and generates a sensing signal. One of the first sensing element 31 and the second sensing element 32 is configured as a sensing element, while the other is configured as a sensor for sensing the sensing element. For example, in this embodiment, the first sensing member 31 is configured as a sensor, and the two second sensing members 32 are configured as sensors. Thus, the connecting cable connected to the second sensing member 32 can be fixed relative to the mounting bracket 330, thereby shortening the connecting cable connected to the second sensing member 32 and preventing the second sensing member 32 from moving relative to the limiting rod 13, which would cause an abnormal electrical connection between the second sensing member 32 and the connecting cable. This can thereby improve the reliability and stability of the detection of the second sensing member 32. In some embodiments, the first sensing member 31 can be configured as a sensor, and the two second sensing members 32 can be configured as a sensing member.

[0179] The first sensing member 31 is fixed relative to the limiting rod 13, so that the first sensing member 31 can rotate synchronously with the limiting rod 13, thereby improving the accuracy of the second sensing member 32 in detecting the rotational position of the first sensing member 31 relative to the mounting bracket 330. The first sensing member 31 is embedded in the limiting rod 13 and is located at the end of the limiting rod 13 away from the connecting rod 11. A mounting groove is provided at the end of the limiting rod 13 facing away from the connecting rod 11, and the first sensing member 31 is provided in the mounting groove, which simplifies the assembly of the first sensing member 31, improves assembly efficiency, reduces the space occupied by the first sensing member 31, and makes the overall structure of the swing module 300 more compact. In one possible implementation, the first sensing member 31 is mounted on the limiting rod 13 by gluing or other structures, which is not specifically limited in this application.

[0180] In one possible implementation, the second sensing element 32 is arranged on the side of the mounting bracket 330 facing away from the swing arm 10, that is, the second sensing element 32 and the driving component 320 are arranged on the same side of the swing arm 10, so that the second sensing element 32 is hidden under the mounting bracket 330, preventing external moisture or debris from damaging the second sensing element 32, improving the detection accuracy and precision of the second sensing element 32, and extending its service life; on the other hand, it improves space utilization, making the overall structure of the swing module 300 more compact.

[0181] The second sensor 32 senses the first sensor 31 to determine its active position, and thus the swing angle of the swing wing 20. The two second sensors 32 are spaced apart along the swing direction of the limiting lever 13. Specifically, the two second sensors 32 can be located on opposite sides of the swing range of the limiting lever 13. Driven by the swing lever 10, the first sensor 31 on the limiting lever 13 can move away from one of the second sensors 32 and toward the other. When the first sensor 31 rotates to a position opposite the second sensor 32, the second sensor 32 generates a sensing signal. The grass collecting device 1000 controls the driver 41 to stop driving based on the sensing signal. Thus, the driver 41 and the sensing component 30 work together to precisely control the opening angle of the grass collecting box 200, avoiding transmission failure or backlash in the driver 320 that could compromise user experience. This also prevents damage to the grass collecting box 200 and the driver 320, improving the reliability and safety of the swing module 300's automated flipping.

[0182] The sensing component 30 further includes a circuit board 33 fixedly connected to the fixed structure, and a second sensing element 32 is provided on the circuit board 33 .

[0183] A slot 3301 is provided on the first bracket 51 near the limiting hole 5102 to form a fixed structure, and the circuit board 33 is snapped into the slot 3301 .

[0184] In one possible implementation, the sensing component 30 also includes a circuit board 33. A second sensing member 32 is provided on the circuit board 33, and is fixedly connected to the fixed structure. For example, in this embodiment, the circuit board 33 is fixedly connected to the mounting bracket 330. Specifically, a card slot 3301 is provided at a position near the limiting hole 5102 of the first bracket 51 to form a fixed structure, and the circuit board 33 is clamped in the card slot 3301. Thus, on the one hand, the assembly of the circuit board 33 and the mounting bracket is shortened, and the assembly efficiency is improved; on the other hand, the circuit board 33 will not increase the size of the swing module 300 in the height direction Z, thereby improving space utilization. In one possible implementation, a positioning column is protruding from the card slot 3301, and the circuit board 33 is provided with a positioning hole that cooperates with the positioning column, thereby facilitating assembly and improving the reliability and stability of the connection between the circuit board 33 and the mounting bracket 330.

[0185] The two second sensors 32 are located on the same side of the circuit board 33 facing the stop rod 13 and are electrically connected to the circuit board 33, thereby simplifying wiring. The circuit board 33 and the main control board of the grass collecting device 1000 can be separate or integrated. The two second sensors 32 are located at opposite ends of the circuit board 33 in the longitudinal direction X of the grass collecting device 1000. The central angle of the line connecting the two second sensors 32 and the axis of the swing rod 10 corresponds to the tilt angle of the grass collecting box 200.

[0186] The second sensing element 32 is spaced apart from the limiting rod 13 . In other words, the end surface of the second sensing element 32 facing away from the circuit board 33 is spaced apart from the end surface of the limiting rod 13 facing the circuit board 33 , thereby avoiding interference with the swinging motion of the swing module 300 .

[0187] The limit rod 13 can cooperate with the sensing component 30 to control the swing of the swing arm 10. It is understandable that the limit rod 13 can cooperate with the sensing component 30 to change the swing direction of the swing arm 10. For example, when the limit rod 13 is located at the first limit position or the second limit position, the second sensing component 32 can sense the first sensing component 31 and generate a sensing signal. When the second sensing component 32 senses the first sensing component 31, the circuit board 33 can control the driving component 41 to stop driving, and control the driving component 41 to reverse drive when starting again. It is understandable that the reverse drive of the driving component 41 can make the rotation direction of the output shaft 43 opposite to the rotation direction before stopping rotation, thereby changing the swing direction of the swing arm 10.

[0188] For example, in this embodiment, the first sensing element 31 is a magnetic element, and the second sensing element 32 is a Hall effect sensor. When the Hall effect sensor senses the magnetic induction intensity of the magnetic element, it generates a corresponding sensing signal. The Hall effect sensor then transmits the generated sensing signal to the circuit board 33, which then controls the driver 41 to stop driving based on the received sensing signal. In some embodiments, the second sensing element 32 may also include, but is not limited to, a distance sensor, an optical coupler sensor, or a pressure sensor. Distance sensors include, but are not limited to, displacement sensors, proximity sensors, and ultrasonic sensors.

[0189] In one possible implementation, the sensing component 30 may not include the first sensing element 31. For example, when the second sensing element 32 is configured as an optical coupler sensor, the end of the limit rod 13 facing away from the connecting rod 11 can function as the first sensing element 31. When the end of the limit rod 13 facing away from the connecting rod 11 blocks the optical coupler sensor, the optical coupler sensor generates a sensing signal; when the end of the limit rod 13 facing away from the connecting rod 11 exposes the optical coupler sensor, the optical coupler sensor does not generate a sensing signal. In one possible implementation, the number of second sensing elements 32 may include one, three, or more, and this application does not impose any specific limitations.

[0190] The limit rod 13 has a first limit position and a second limit position. The first limit position and the second limit position are respectively two positions to which the limit rod 13 swings relative to the two second sensing members 32. When the grass collecting device 1000 is in the grass collecting state, the limit rod 13 is located at the first limit position, and the limit rod 13 is located at the initial position. When the grass collecting device 1000 enters the grass unloading state from the grass collecting state, the limit rod 13 swings from the first limit position to the second limit position. The magnetic member provided on the limit rod 13 is arranged opposite to one of the Hall sensors. After the limit rod 13 swings, it drives the magnetic member to rotate to a position opposite to the other Hall sensor. The controller controls the driving member 41 to stop working. At this time, the swinging wing 20 drives the grass collecting box 200 to flip outward relative to the grass collecting bracket 100, so that the grass collecting device 1000 is in the grass unloading state, thereby achieving the grass collecting box 200 flipping and dumping grass clippings. When the grass collecting device 1000 enters the grass collecting state from the grass unloading state, when the driving member 41 is started again, the controller can control the driving member 41 to drive in the reverse direction. At this time, the limit rod 13 can rotate in the reverse direction, driving the limit rod 13 to move from the second extreme position to the first extreme position. At this time, the swing wing 20 drives the grass collecting box 200 to flip inward relative to the grass collecting bracket 100, so that the grass collecting box 200 returns to the initial position, that is, it is in the grass collecting state.

[0191] The sensing component 30 of the present application includes a first sensing component 31 and multiple second sensing components 32. The first sensing component 31 is arranged on the limit rod 13. The swing rod 10 drives the limit rod 13 to rotate together with the first sensing component 31. When the first sensing component 31 rotates to a position directly opposite to any second sensing component 32, the second sensing component 32 arranged opposite to the first sensing component 31 can sense the first sensing component 31 and generate a sensing signal. The circuit board 33 receives the sensing signal generated by the second sensing component 32 and controls the driving component 41 to stop driving. The circuit board 33 is also used to control the driving component 41 to drive in reverse when the driving component 41 is started again, thereby achieving precise control of the opening angle of the grass collecting box 200, avoiding the problem of transmission failure or transmission gap of the driving component 320 that reduces the user experience, and at the same time avoiding damage to the grass collecting box 200 and the driving component 320, thereby improving the reliability and safety of the automatic flipping of the grass collecting box 200.

[0192] Referring again to FIG. 11 , an embodiment of the present application further provides a lawn mowing device, comprising a lawn mower and the aforementioned grass collection box 200 or the aforementioned grass collection device 1000, wherein the grass collection box 200 or the grass collection device 1000 is connected to the rear end of the lawn mower.

The lawn mowing device can move on the ground. For example, the lawn mowing device can move on the ground when pushed by a user. For another example, the lawn mowing device can be mobile and can automatically move on the ground via a drive mechanism.

[0193] The lawn mower includes but is not limited to a frame, a cutting mechanism, and a lifting mechanism. The grass collecting device 1000 or the grass collecting box 200 is arranged at the rear of the frame. For example, the grass collecting bracket 100 is detachably arranged on the frame of the lawn mower, so that the grass collecting device 1000 can be removed from the frame of the lawn mower, which is convenient for maintenance and replacement, and enriches the different application scenarios of the lawn mower, such as mowing scenes, grass collecting scenes, or mowing and collecting scenes. In some embodiments, the grass collecting bracket 100 can also be non-detachably arranged on the frame of the lawn mower, which is not specifically limited in this application. The cutting mechanism and the lifting mechanism are arranged on the frame. The lifting mechanism is used to drive the cutting mechanism to move along the height direction Z of the grass collecting device 1000. The cutting mechanism is used to cut grass.
