[0038] According to another aspect of the present application, a lawn mower is provided, comprising the above-mentioned grass collecting bag assembly, or comprising the above-mentioned grass collector.

[0039] The utility model has the following technical effects:

[0040] 1. Related Art: A rigid cover covers the entire top of the bag, connecting and supporting it. Large rigid covers are heavy, resulting in a heavier overall bag. Therefore, the present invention removes a portion of the rigid cover and replaces it with a support rod and the top surface of the bag. The remaining portion of the rigid cover serves as a top cover, connecting the grass collector body to the support rod. First, because the top cover no longer needs to directly connect and support the bag, it can be designed to be lightweight and compact, making the top cover itself even lighter.

[0041] Secondly, the support rod, as a rod-shaped material, weighs less than the replaced hard cover when combined with the added top cover, further reducing the overall weight of the grass collecting hood assembly. At the same time, the support rod maintains a certain shape, providing stable support for the hood, thereby resolving the technical issues in related art where excessive weight of grass collecting hood assemblies leads to high costs, affecting flexibility and efficiency. Furthermore, by reducing the weight of the grass collecting hood assembly, the center of gravity of the lawn mower can be more easily maintained in a forward position, reducing counterweight, further reducing costs, and improving stability.

[0042] In addition, since the present invention still retains the top cover as a structure connecting the grass collector body and the support rod, and the top cover has a certain length and width, it can cover a portion of the top of the bag body after being installed on the top of the bag body. Therefore, a notch can be provided on the top of the bag body, the notch corresponding to the top cover, and the top cover can cover the notch, thereby reducing the weight of the top of the bag body and further reducing the overall weight of the grass collector bag assembly.

[0043] 2. By making the gap between the top cover and the top pocket surface less than 5 mm, the back side of the top cover can be close to the front side of the top pocket surface, preventing weeds from leaking out of the gap between the back side of the top cover and the front side of the top pocket surface.

[0044] 3. By matching the length and width of the top cover to the notch and positioning it above the notch, the top cover overlaps the top of the notch on the hopper body. This reduces the gap between the left and right sides of the top cover and the notch, preventing weeds from escaping. This also minimizes the size of the top cover to reduce weight. Furthermore, positioning the top cover above the notch prevents it from encroaching on the grass collection cavity of the hopper body, maximizing the use of the space within the cavity.

[0045] 4. By making the portion connecting the side pocket surface and the top pocket surface protrude vertically beyond the notch, and with the protruding portion close to the rear end of the top cover, the rear end of the top cover can be utilized to expand the grass collection cavity within the pocket body, thereby providing a larger grass collection cavity. Furthermore, with this arrangement, the top pocket surface can be closer to the top of the top cover, preventing the top cover from protruding too much, making it easier to use.

[0046] 5. By detachably and fixedly connecting the support rod and the top cover, it is easy to store and can reduce the transportation volume.

[0047] 6. The supporting rod includes a first rod body and a second rod body, and a hanging portion is provided on the top pocket surface. The top pocket surface is sleeved on the first rod body, and the hanging portion is hung on the second rod body. During installation, the top pocket surface is directly sleeved on the first rod body, and the hanging portion is hung on the second rod body. This ensures a stable connection and is convenient for installation. The cooperation between the hanging portion and the second rod body can prevent the pocket body from moving backward, thereby improving the stability of use.

[0048] 7. By locating the hanging portion on one end of the top pocket surface close to the top cover, it is convenient to hang the hanging portion on the second rod when the pocket body is installed on the supporting rod.

[0049] 8. By providing a hanging interface on the side of the hanging part opposite to the bottom of the bag body, after the hanging interface is assembled with the second rod body, it can better resist the downward gravity exerted on the bag body during use, and can prevent the hanging interface from being separated from the second rod body under the action of this force, thereby improving the stability of use.

[0050] 9. Through the flexible connection between the hanging part and the top pocket surface, the hanging part can be flipped relative to the top pocket surface to change the position of the hanging interface. After the hanging interface is set on the side opposite to the bottom of the pocket body, the direction of the hanging interface can be changed through the flexible connection part during installation, making it easier to hang on the second rod body.

[0051] 10. By setting the first rod body and the second rod body as a split structure, the first rod body and the second rod body are respectively detachably fixedly connected to the first end and the second end of the top cover, which can reduce production costs and facilitate user self-installation. Moreover, after the first rod body and the second rod body are designed as split bodies, the structural design of each rod body is more flexible and production is more convenient.

[0052] 11. The first rod body includes a side rod and an end rod, two side rods are provided and distributed relatively to each other, the end rod is fixed between the two side rods, the top pocket surface is sleeved on the side rods and the end rods and tightened, and the end of the side rod away from the end rod is detachably fixedly connected to the first end of the top cover. The side rod and the end rod can be used to jointly support the top pocket surface of the pocket body, which can not only keep the top pocket surface flat, but also better stretch the side pocket surface to keep it in the expanded state.

[0053] 12. A first clamping portion is provided on one end of the side rod away from the end rod, and a second clamping portion is provided on the first end of the top cover. The second clamping portions are located on both sides of the top cover and correspond to the two side rods respectively. The first clamping portion and the corresponding second clamping portion are clamped together, so that the side rod and the top cover can be connected in a clamping manner, thereby facilitating the installation and disassembly of the side rod.

[0054] 13. By making the first clamping part include a clamping rod and the second clamping part include a clamping hole; or, the first clamping part includes a clamping hole and the second clamping part includes a clamping rod; through the elastic deformation of the side rod, the clamping rod is aligned with the clamping hole and is clamped into the clamping hole under the action of elastic force, the clamping rod and the clamping hole can be docked during installation by only pulling the side rod outward or squeezing the side rod inward to cause the side rod to produce elastic deformation, thereby further reducing the difficulty of installation and disassembly.

[0055] 14. A side wall is provided on one end of the top cover close to the side rod, the side wall corresponds to the side rod, and a mounting hole is provided on the side wall. The first clamping portion can pass through the mounting hole and be clamped with the second clamping portion. The bottom wall of the mounting hole abuts against the side rod to limit the rotation of the side rod. When the front end of the side rod is inserted into the mounting hole, the wall of the mounting hole fits with the side rod, thereby limiting the downward and upward rotation of the side rod, thereby preventing the bag body from swinging during use and improving the stability of use.

[0056] 15. By setting two side walls and locating them on both sides of the top cover, there is a spacing between the two side walls to form a mounting channel, the width of the mounting channel matches the width of the hanging portion, and the hanging portion can pass through the mounting channel, so that the hanging portion located at the front end of the top pocket surface can be connected to the second rod body through the mounting channel, so that the front end of the top pocket surface can be closer to the rear end surface of the top cover, and the gap between the top pocket surface and the top cover can be reduced.

[0057] 16. By setting the card rod to be U-shaped, the first end of the card rod is connected to the end of the side rod, and the second end of the card rod is engaged with the card hole. After the card rod is set to be U-shaped, the bending space of the card rod can make the rod section at the front end of the card rod and the card hole have a longer contact length. At the same time, the side rod can also be close to the edge of the top cover, the wall thickness of the top cover does not need to be increased additionally, and the outer surface of the top cover can be kept flat.

[0058] 17. The second rod body includes a connecting rod segment and a sinking rod segment, the connecting rod segment is connected to the second end of the top cover, and a gap is provided between the top of the sinking rod segment and the top cover to form a hanging channel. After the hanging channel is formed, the hanging portion at the front end of the top pocket can be hung on the sinking rod segment through the hanging channel. The connecting rod segment can include a horizontal segment, which can be used to simply and stably connect the connecting rod segment to the top cover, thereby fixing the second rod body.

[0059] 18. By setting a tube clamp pressing piece with a pressing groove, the tube clamp pressing piece is detachably fixedly connected to the top cover, and the second rod body is pressed onto the top cover through the pressing groove, the second rod body can be more stably fixed to the top cover, thereby enabling the bag body to be more stably connected and fixed.

[0060] 19. A rod body mounting groove is provided at the second end of the top cover, and the rod body mounting groove is used to accommodate and position the second rod body; a pressure piece mounting groove is also provided on the top cover, and the pipe clamp pressure piece can be detachably fixed in the pressure piece mounting groove.

[0061] 20. By connecting the first rod and the second rod to form a frame, the first rod and / or the second rod are detachably fixedly connected to the top cover. During installation, the support rod can be installed by simply connecting the first rod or the second rod to the top cover, which can simplify the installation steps.

[0062] 21. By having two or more connection positions between the support rod and the top cover in the front-to-back direction, the connection position can be changed during use, and the length of the support rod extending out of the rear of the top cover can be changed to match pockets of different sizes, thereby improving flexibility of use.

[0063] 22. By making the support rod retractable in the front-to-back direction, the length of the support rod extending out of the top cover can be changed to match pockets of different sizes, which can also improve the flexibility of use.

[0064] 23. By setting an inlet support frame, the grass inlet of the bag body is provided with a buckle groove, and the inlet support frame is detachably buckled in the buckle groove, so that the inlet support frame can support the more flexible grass inlet of the bag body and keep the grass inlet in an expanded state to facilitate docking with the grass collector body.

[0065] 24. By making the bag body out of flexible materials, it is easier to expand the versatility of the bag body, so that it can be fixed into the desired shape through supporting rods to adapt to different scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0081] like Figures 1 to 4 As shown, the embodiment of the present invention provides a grass collecting bag assembly 9, which is suitable for being connected to the rear of the grass collector body 6. The grass collecting bag assembly 9 includes:

[0082] The bag body 3 has a grass collecting cavity 36 and a grass inlet 35 connected to the grass collecting cavity 36. The top of the bag body 3 includes a top bag surface 31 and a notch 32 located on one side of the top bag surface 31;

[0083] The top cover 1 includes a hard cover body, which is used to connect with the grass collector body 6. The top cover 1 corresponds to the notch 32. The top pocket surface 31 and the top cover 1 together form the top of the grass collecting pocket assembly 9.

[0084] The support rod 2 is connected to the rear of the top cover 1 and extends backward to connect with the top pocket surface 31. The support rod 2 supports the pocket body 3 and keeps the pocket body 3 in the expanded state;

[0085] The sum of the weights of the support rod 2 and the top pocket surface 31 is less than the weight of a hard cover having the same coverage area as the top pocket surface 31 .

[0086] In this embodiment, the grass collecting pocket assembly 9 can be connected to the rear of the grass collecting body 6. The grass collecting body 6 can be a structure pre-installed on the rear of the lawn mower body. The lawn mower body, the grass collecting body 6, and the grass collecting pocket assembly 9 together constitute the lawn mower. Grass cut by the lawn mower body is transported through the grass collecting body 6 to the grass collecting pocket assembly 9 for storage.

[0087] like Figure 1 and Figure 2 As shown, the grass collecting hood assembly 9, which serves as a component for storing weeds during mowing, mainly includes a hood body 3, a top cover 1, and a support rod 2. The hood body 3 has a grass collecting cavity 36 and a grass inlet 35 connected to the grass collecting cavity 36. A notch 32 and a top hood surface 31 are provided at the top of the hood body 3. The grass inlet 35 can be located at one end of the hood body 3 near the grass collector body 6. When the grass collecting hood assembly 9 is connected to the rear of the grass collector body 6, the grass inlet 35 of the hood body 3 docks with the grass outlet at the rear end of the grass collector body 6. The weeds collected by the grass collector body 6 are discharged from the grass outlet and enter the grass collecting cavity 36 through the grass inlet 35 for storage.

[0088] The top cover 1 is mounted on top of the hood 3, specifically at a location corresponding to the notch 32. The top cover 1 comprises a relatively rigid structure for connection to the grass collector body 6, thereby providing good connection stability and strength. Furthermore, when aligned with the notch 32, the top cover 1 can at least partially or completely obscure the notch 32. The notch 32 also provides space for the top cover 1, facilitating connection of the hood 3 to the support rod 2 during installation.

[0089] The support rod 2 is connected to the rear of the top cover 1 (i.e., the end of the top cover 1 away from the grass collector body 6), and extends backward to connect with the top pocket surface 31 of the pocket body 3. The pocket body 3 is directly supported by the support rod 2 so that the pocket body 3 remains in the grass collecting state.

[0090] As can be seen, the present invention removes a portion of the rigid cover and replaces it with the support rod and the top surface 31 of the bag body 3. The remaining portion of the rigid cover serves as the top cover 1, connecting the grass collector body 6 and the support rod 2. First, since the top cover 1 no longer needs to directly connect and support the bag body 3, it no longer needs to match the length of the bag body 3. Therefore, the length of the top cover 1 along the length of the bag body 3 can be reduced, and this reduced length reduces the weight of the top cover 1. This allows for a lightweight and compact design, making the top cover 1 even lighter.

[0091] Secondly, the support rod 2, as a rod-shaped material, weighs less than the replaced hard cover when combined with the added top cover 31, further reducing the overall weight of the grass collecting hood assembly. At the same time, the support rod 2 maintains a certain shape, providing stable support for the cover 3. This solves the technical problem of excessive weight of grass collecting hood assemblies in related art, resulting in high costs and affecting flexibility and efficiency. Furthermore, by reducing the weight of the grass collecting hood assembly, the center of gravity of the lawn mower can be more easily maintained in a forward position, reducing counterweight, further reducing costs, and improving stability.

[0092] In addition, since the top cover 1 is still retained in the present invention as a structure connecting the grass collector body 6 and the support rod 2, and the top cover 1 has a certain length and width, it can cover a portion of the top of the bag body 3 after being installed on the top of the bag body 3. Therefore, a notch 32 can be provided on the top of the bag body 3, and the notch 32 corresponds to the top cover 1. The top cover 1 can cover the notch 32, thereby reducing the weight of the top of the bag body 3 and further reducing the overall weight of the grass collector assembly.

[0093] In summary, the top structure of the bag body 3, which is primarily composed of the top cover 1, the support rod 2, and the top cover surface 31, in this embodiment can reduce the overall weight of the grass collecting bag assembly 9 compared to designs in which the top structure of the bag body 3 is composed entirely of a plate. At the same time, the support rod 2 can maintain a certain shape, providing stable support for the bag body 3. Furthermore, the retained top cover 1 can stably connect the grass collecting bag assembly 9 to the grass collector body 6. In particular, when the grass collecting bag assembly 9 is capable of flipping relative to the grass collector body 6, the connection between the grass collector body 6 and the support rod 2 via the top cover 1 ensures stability of movement.

[0094] The grass collecting scoop assembly 9 and the grass collector body 6 can be separate structures. When in use, the assembled grass collecting scoop assembly 9 is installed behind the grass collector body 6. In one embodiment, the grass collecting scoop assembly 9 can be flipped relative to the grass collector body 6 after installation, thereby dumping the weeds inside the grass collecting scoop assembly 9. The flipping process can be manual or automatic. If automatic flipping is used, a corresponding flipping motor is installed in the grass collector body 6, which drives the entire grass collecting scoop assembly 9 to flip.

[0095] In another embodiment, the grass collecting pocket assembly 9 is connected to the grass collector assembly via a quick-release structure, allowing it to be easily removed from the grass collector body 6, thereby emptying the weeds in the grass collecting pocket assembly 9. In this embodiment, the connection structure and method of the grass collecting pocket assembly 9 and the grass collector body 6 are not restrictive and can be designed according to actual needs.

[0096] The specific form of the grass collecting cavity 36 of the bag body 3 is not limited in this embodiment and can be designed according to needs. In one embodiment, the cross-section of the grass collecting cavity 36 is rectangular and extends a certain length toward the rear of the grass collector body 6.

[0097] In addition, in this embodiment, the bag body 3 can also be set to a variety of structural forms, as long as it can satisfy the requirements of having a grass collecting cavity 36 and a grass inlet 35. For example, in one embodiment, the bag body 3 is a net bag, which includes a bottom mesh surface, a side mesh surface, and a top mesh surface, the three of which together form a grass collecting cavity 36 and form a grass inlet 35 at one end. Specifically, the bottom mesh surface and the top mesh surface are arranged opposite to each other, and the side mesh surface is connected between the bottom mesh surface and the top mesh surface. Taking the bottom mesh surface and the top mesh surface having four side edges as an example, the side mesh surface can be only arranged on three side edges, and the side without the side mesh surface naturally forms the grass inlet 35. In this embodiment, setting the bag body 3 as a net bag can effectively reduce the weight of the bag body 3.

[0098] In another embodiment, the pocket body 3 comprises a bottom plate, side mesh panels, and a top mesh panel. The top mesh panel and bottom plate are positioned opposite each other, with the side mesh panels connected between the bottom plate and the top mesh panel. Compared to the pocket body 3 of the previous embodiment, this embodiment replaces the bottom mesh panel with a bottom plate. The bottom plate has greater rigidity than the mesh panel, thus providing better support. Accordingly, the weight of the bottom plate is also greater than that of the mesh panel. Therefore, the appropriate pocket body 3 structure can be selected based on actual needs.

[0099] In the present invention, it is preferred that the bag body 3 is made of a lighter flexible material, such as a mesh or a film, at least on the side, so as to effectively reduce the weight of the bag body 3.

[0100] In addition, the expanded state in this embodiment refers to the state in which the bag body 3 is supported and fixed, and the bag body 3 can remain in this state during the grass collecting process. For example, if the sides, top, and bottom of the bag body 3 are made of flexible materials, when the bag body 3 is in the grass collecting state, at least the sides of the bag body 3 are in a stretched and expanded state.

[0101] Since the present invention still retains the top cover 1 as a structure connecting the grass collector body 6 and the support rod 2, and the top cover 1 has a certain length and width, it can cover a portion of the top of the bag body 3 after being installed on the top of the bag body 3. Therefore, the area on the top of the bag body 3 corresponding to the top cover 1 does not need to be provided with a bag surface, and the top cover 1 is used to cover a portion of the top surface of the bag body 3, thereby further reducing the material consumption of the bag body 3 and thus reducing the weight. Specifically, Figure 2 As shown, in this embodiment, a notch 32 is provided on the top of the pocket body 3 , the notch 32 corresponds to the top cover 1 , and the notch 32 is closed by the top cover 1 .

[0102] In the present invention, a notch 32 is provided at the top of the pocket body 3 , and the top cover 1 corresponds to the notch 32 . The specific structural form of the notch 32 can be determined according to the structure of the top cover 1 , and it only needs to be satisfied that the top cover 1 can cover the notch 32 after assembly.

[0103] In one embodiment, a portion of the top cover 1 can extend into the pocket body 3 through the notch 32, and the side walls of the top cover 1 fit in with the side surfaces of the pocket body 3. Figure 1 As shown, the top cover 1 is disposed above the notch 32, with the side of the top cover 1 opposite the bottom of the pocket 3 (i.e., the lower surface of the top cover 1) shielding the notch 32. The second embodiment is preferred in the present invention, in which the top cover 1 does not intrude into the pocket 3, thereby ensuring a sufficiently large grass collection space within the pocket 3.

[0104] When the top cover 1 is installed to the position corresponding to the notch 32, the rear side of the top cover 1 is close to the front side of the top pocket surface 31. In order to prevent weeds from leaking out from the gap between the rear side of the top cover 1 and the front side of the top pocket surface 31, it is preferred that the gap between the top cover 1 and the top pocket surface 31 is less than 5 mm.

[0105] In one embodiment, Figure 2 As shown, the notch 32 is a generally rectangular opening, and the corresponding top cover 1 has a rectangular lower surface. The length and width of the top cover 1 match the length and width of the notch 32 and can be slightly larger than the width of the notch 32, so that the top cover 1 can overlap the top of the notch 32 area on the pocket body 3, making it difficult to form a gap between the left and right sides of the top cover 1 and the notch 32.

[0106] like Figure 2As shown, since the top cover 1 needs to be connected to the grass collector body 6, which is located in front of the grass inlet 35, to simplify the connection method and structure between the top cover 1 and the grass collector body 6, the top cover 1 is preferably close to the grass collector body 6, that is, close to the grass inlet 35. Correspondingly, the notch 32 in the bag body 3 is also close to the grass inlet 35. Furthermore, when using the automatic flipping and dumping method, the flipping motor in the grass collector body 6 needs to transmit torque to the top cover 1, which in turn transmits torque to the support rod 2, thereby driving the entire bag body 3 to flip. When the top cover 1 is close to the grass collector body 6, it facilitates force transmission during the flipping process and improves movement stability.

[0107] To maximize the use of the space within the pocket body 3, the top cover 1 is installed above the notch 32 at the top of the pocket body 3. In this case, the top pocket surface 31 of the pocket body 3 has at least two structural forms. One form is that the top pocket surface 31 is flush with the notch 32, and the top cover 1 protrudes from the pocket body 3. Another form is that the top pocket surface 31 is flush with or close to the top of the top cover 1. In the first form, the side of the top cover 1 is not fully utilized, resulting in a small overall volume of the pocket body 3, and the top cover 1 protrudes too much from the pocket body 3, affecting its use. In the second form, the pocket body 3 can have a larger volume, and the top of the top cover 1 can be kept flush with or close to the top pocket surface 31, making it more convenient to use.

[0108] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the pocket body 3 includes a side pocket panel 30, which is connected to the top pocket panel 31. The portion where the side pocket panel 30 and the top pocket panel 31 are connected vertically protrudes beyond the notch 32, and the protruding portion is in contact with the rear end surface of the top cover 1. The length by which the side pocket panel 30 protrudes beyond the notch 32 can be close to the height of the top cover 1, so that the top pocket panel 31 located at the top of the side pocket panel 30 can be close to the top of the top cover 1.

[0109] Since the support rod 2 is connected to the rear of the top cover 1, it is preferably detachably fixed to the top cover 1 to facilitate storage and reduce transport volume. Specifically, the front end of the support rod 2 and the top cover 1 can be connected via a snap fastener, screws, or other similar means. To facilitate subsequent installation and removal, a snap fastener connection is preferred. The specific connection structure is not limited in this embodiment and can be designed based on actual needs.

[0110] In the present invention, the support rod 2 is used to connect with the bag body 3 to support the bag body 3 and keep the bag body 3 in the grass collecting state. In the grass collecting state, the side pocket surface 30 of the bag body 3 needs to be in a stretched and expanded state. Figure 2As shown, in this embodiment, the support rod 2 is preferably connected to the top pocket surface 31, and the support rod 2 supports and fixes the top pocket surface 31 to maintain the pocket body 3 in the grass collecting state. In this embodiment, the top pocket surface 31 does not need to be provided with an additional structure for assembling with the support rod 2, which can simplify the structure of the top pocket surface 31 and is more convenient and quick during installation. At the same time, after the support rod 2 is connected to the top pocket surface 31, it can support the pocket body 3 and keep the top pocket surface 31 in a flat state, thereby enabling the pocket body 3 to reach its maximum volume state, which is conducive to collecting grass.

[0111] When the support rod 2 directly contacts the bottom surface of the top pocket surface 31 to support the pocket body 3, in order to prevent the pocket body 3 from sliding backward, the position of the pocket body 3 needs to be fixed. Figure 2 As shown, the support rod 2 includes a first rod body 20 and a second rod body 21, and a hanging portion 33 is provided on the top cover 31. The top cover 31 is sleeved on the first rod body 20, and the hanging portion 33 is hung on the second rod body 21. The first rod body 20 and the second rod body 21 can be an integral structure or can be as shown in FIG. Figure 2 In the split structure shown, the first rod 20 and the second rod 21 are separately installed on the top cover 1.

[0112] Specifically, in this embodiment, the support rod 2 includes at least two parts, namely a first rod 20 and a second rod 21, wherein the first rod 20 extends backward relative to the top cover 1, and the top pocket surface 31 of the pocket body 3 is sleeved on the first rod 20, and the top pocket surface 31 is supported by the first rod 20. The first rod 20 and the second rod 21 can be an integral structure or a separate structure. The second rod 21 can be located in the front area of the first rod 20. During installation, the top pocket surface 31 of the pocket body 3 is sleeved on the first rod 20, and the hanging portion 33 on the top pocket surface 31 is hung on the second rod 21. The position of the pocket body 3 is fixed by the cooperation of the hanging portion 33 and the second rod 21, thereby preventing the pocket body 3 from moving backward relative to the support rod 2.

[0113] In this embodiment, the first rod 20 needs to support the top cover 31. Therefore, the first rod 20 includes at least two opposing side rods 200, each connected to either side of the top cover 31 to jointly support the top cover. A connecting rod can be provided between the two side rods 200. When the connecting rod is provided at the rear end of the side rod 200, the first rod 20 has an overall U-shape. When the connecting rod is provided in the middle of the side rod 200, the first rod 20 has an overall H-shape. Of course, this is not restrictive and can be designed based on actual needs. The attachment portion 33 on the top cover 31 can be located in any position as long as it can cooperate with the second rod 21 to secure the cover 3. When the second rod 21 is located in the front area of the first rod 20, the attachment portion 33 is preferably located in the front area of the top cover 31.

[0114] In one embodiment, Figure 2 As shown, the hanging portion 33 is located on the top pocket surface 31 at one end close to the top cover 1, so that when the pocket body 3 is installed on the support rod 2, it is convenient to hang the hanging portion 33 on the second rod body 21. According to the different structures of the hanging portion 33, different hanging methods are adopted during installation. The hanging port 330 of the hanging portion 33 can be located at the upper part of the top pocket surface 31, or at the lower part of the top pocket surface 31. When the hanging port 330 of the hanging portion 33 is located at the upper part of the top pocket surface 31, the second rod body 21 is also located at the upper part of the top pocket surface 31 after assembly. Similarly, when the hanging port 330 of the hanging portion 33 is located at the lower part of the top pocket surface 31, the second rod body 21 is located at the lower part of the top pocket surface 31 after assembly.

[0115] During the grass collecting process, the bag body 3 is subjected to the downward gravity, and accordingly the hooking portion 33 is also subjected to the downward traction force. Therefore, in order to prevent the hooking portion 33 from being separated from the second rod body 21 under the action of this force, Figure 2 As shown, in this embodiment, the hanging port 330 of the hanging portion 33 is preferably set at the lower part of the top pocket surface 31, that is, the hanging port 330 is set on the side of the hanging portion 33 opposite to the bottom pocket surface.

[0116] In one embodiment of the hanging portion 33, the hanging portion 33 may be one or more hooks (not shown in the figure) provided at the front end of the top pocket surface 31, and the plurality of hooks may be distributed at intervals. Figure 2 As shown, the hooking portion 33 can also be an elongated structure located at the front end of the top cover 31. If the hooking portion 33 is configured as multiple hooks, each hook must be attached to the second rod 21 individually during installation, which is inconvenient. To maximize installation efficiency, it is desirable to reduce the number of hooking portions 33. In a limited space, the contact area between a small number of hooks and the second rod 21 is smaller than that between a long hooking portion 33 and the second rod 21, resulting in less stable connection. Therefore, it is preferable to configure the hooking portion 33 as an elongated structure.

[0117] When the hooking hole 330 of the hooking portion 33 is disposed below the top pocket surface 31, to ensure sufficient connection stability, the hooking hole 330 should face the rear of the pocket body 3. Therefore, to facilitate the hooking and mating of the hooking portion 33 with the second rod 21, in this embodiment, the hooking portion 33 and the top pocket surface 31 are flexibly connected, so that the hooking portion 33 can be flipped relative to the top pocket surface 31 to change the position of the hooking hole 330.

[0118] Specifically, during installation, the bag body 3 is first sleeved onto the first rod body 20, with the first rod body 20 supporting the top bag surface 31. Before connecting to the second rod body 21, the hook portion 33 is flipped so that its opening faces forward, and the second rod body 21 is inserted into the hook portion 33 through the opening. The hook portion 33 is then flipped back to its original position, with the hook port 330 facing the rear of the bag body 3. This achieves a stable connection between the hook portion 33 and the second rod body 21, and is more convenient during the connection process. The hook portion 33 can be made of a material with a certain hardness, such as polyethylene, and pre-processed into a hook shape. The hook portion 33 can be connected to the top bag surface 31 via a rubber strip or directly connected to the top bag surface 31. When connected via a rubber strip, the elastic force of the rubber strip itself facilitates the reset of the hook portion 33 after being attached to the second rod body 21.

[0119] In the present invention, the first rod 20 and the second rod 21 can be an integral structure or a separate structure. When the two are an integral structure, the support rod 2 is generally in the shape of a square frame (not shown in the figure), and the connection position 160 between the support rod 2 and the top cover 1 can be set on the first rod 20 or on the second rod 21. This embodiment does not limit this. Figure 2 and Figure 3 As shown, when the two are separate structures, the first rod body 20 and the second rod body 21 can be installed at different positions on the top cover 1 in steps.

[0120] To reduce production costs and facilitate user installation, in this embodiment, the first rod 20 and the second rod 21 are split structures, and the first rod 20 and the second rod 21 are removably fixed to the first end and the second end of the top cover 1, respectively. Specifically, the second rod 21 is used to fix the pocket body 3, and therefore the second rod 21 can be pre-installed on the top cover 1. The first rod 20, as a component supporting the pocket body 3, can be installed at the time of use, which simplifies the installation steps on the user side and reduces the installation difficulty. In addition, the split design of the first rod 20 and the second rod 21 makes the structural design of each rod more flexible and more convenient to manufacture.

[0121] In one embodiment of the first rod body 20, as Figure 2As shown, the first rod body 20 includes a side rod 200 and an end rod 210. The side rods 200 are set as two and distributed relatively to each other. The end rod 210 is fixed between the two side rods 200. The top pocket surface 31 is sleeved on the side rods 200 and the end rods 210 and tightened; the end of the side rod 200 away from the end rod 210 is detachably fixedly connected to the first end of the top cover 1.

[0122] Specifically, in this embodiment, the end rod 210 can be disposed between the rear ends of the two side rods 200 or between the middle portions of the two side rods 200. To better support the pocket body 3, the end rod 210 is preferably disposed between the rear ends of the two side rods 200, thereby evenly supporting the top pocket surface 31 of the pocket body 3 and providing better support for the side pocket surfaces of the pocket body 3.

[0123] The side bars 200 and end bars 210 can be integral or separate structures, preferably integral structures, which can simplify installation steps and improve structural stability. During processing, they can be formed by bending a straight bar, and the side bars 200 and end bars 210 are different sections of the straight bar after bending. The end of the side bar 200 away from the end bar 210 (i.e., the front end of the side bar 200) is detachably connected to the first end of the top cover 1 (i.e., the rear end of the top cover 1). The specific connection method can be a snap connection, plug-in connection, or a screw connection, etc., which is not limited in this embodiment.

[0124] In order to facilitate the connection between the side bar 200 and the top cover 1, in this embodiment, the side bar 200 and the top cover 1 are preferably snap-fitted. Figure 2 and Figure 4 As shown, a first clamping portion 220 is provided on the end of the side rod 200 away from the end rod 210, and a second clamping portion 150 is provided on the first end of the top cover 1. The second clamping portion 150 is located on both sides of the top cover 1 and corresponds to the two side rods 200 respectively. The first clamping portion 220 and the corresponding second clamping portion 150 are clamped together.

[0125] Specifically, during installation, the first engaging portions 220 on the two side bars 200 are engaged with the second engaging portions 150 on either side of the top cover 1. For example, the second engaging portions 150 are latching holes 1500 in the top cover 1, and the first engaging portions 220 are portions of the front ends of the side bars 200. During installation, the front ends of the side bars 200 are simply inserted into the latching holes 1500. The latching holes 1500 can be oriented in either the front-to-back or left-to-right direction of the top cover 1. When the latching holes 1500 are oriented in the front-to-back direction of the top cover 1, the side bars 200 can be inserted directly into the latching holes 1500 from the rear of the top cover 1. When the latching holes 1500 are oriented in the left-to-right direction of the top cover 1, the first engaging portions 220 are correspondingly configured as latching rods 2200 extending in the left-to-right direction from the front ends of the side bars 200. During installation, the side bars 200 are subjected to a certain degree of elastic deformation to engage the first engaging portions 220 in the latching holes 1500.

[0126] Of the two aforementioned snap-in methods, the second snap-in method can prevent the side bar 200 from directly separating from the top cover 1 compared to the first snap-in method, thereby improving the stability after installation. Therefore, the second snap-in method is preferred.

[0127] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the first engaging portion 220 includes a lever 2200, and the second engaging portion 150 includes a hole 1500. The hole 1500 is oriented in the left-right direction of the top cover 1. The lever 2200 is a rod extending in the left-right direction from the front end of the side bar 200. During installation, the side bar 200 elastically deforms to align the lever 2200 with the hole 1500 and engages the hole 1500 under the action of the elastic force.

[0128] In addition, depending on the opening direction of the latch hole 1500, the latch rod 2200 is oriented differently, resulting in different deformation directions of the side bars 200 during installation. For example, when the latch hole 1500 opens toward the inside of the top cover 1, the latch rod 2200 extends toward the outside of the side bars 200. During installation, the side bars 200 are pushed inward to deform into an inward-facing "eight-shaped" shape, allowing the latch rod 2200 to align with the latch hole 1500 and thus engage with the latch hole 1500. When the latch hole 1500 opens toward the outside of the top cover 1, the latch rod 2200 extends toward the inside of the side bars 200. During installation, the side bars 200 are pulled outward to deform into an outward-facing "eight-shaped" shape, allowing the latch rod 2200 to align with the latch hole 1500 and thus engage with the latch hole 1500.

[0129] It is understood that, under the concept of a clamping connection, the first clamping portion 220 can be configured as a clamping rod 2200 and the second clamping portion 150 can be configured as a clamping hole 1500, or the first clamping portion 220 can be configured as a clamping hole and the second clamping portion 150 can be configured as a clamping rod. Because the first rod body 20 is a rod-shaped structure, the diameter of the first rod body 20 is relatively small to reduce weight. In this case, it is difficult to open a large-diameter hole in the first rod body 20 and it also affects the structural strength. Therefore, it is preferred that the first clamping portion 220 is configured as a clamping rod 2200 and the second clamping portion 150 is configured as a clamping hole 1500.

[0130] In the above-described embodiment, the side bars 200 and the top cover 1 are connected via the engagement rods 2200 and the engagement holes 1500. To facilitate docking, the engagement rods 2200 and the engagement holes 1500 are both circular. During the grass-collecting process, the bag body 3 is subjected to a downward force of gravity, which is transferred to the side bars 200 and applies a downward torque to the side bars 200. When the side bars 200 and the top cover 1 engage only via the circular engagement rods 2200 and the engagement holes 1500, the side bars 200 rotate, causing the bag body 3 to deform. Therefore, after the side bars 200 are connected to the top cover 1, their downward rotational freedom needs to be restricted to prevent them from rotating under the force of gravity on the bag body 3.

[0131] In one embodiment, Figure 3 As shown, a side wall 100 is provided on one end of the top cover 1 close to the side rod 200, and the side wall 100 corresponds to the side rod 200. A mounting hole 110 is provided on the side wall 100, and the first clamping portion 220 can pass through the mounting hole 110 and be clamped with the second clamping portion 150. The bottom wall of the mounting hole 110 abuts against the side rod 200 to limit the rotation of the side rod 200.

[0132] Specifically, the locking hole 1500 is located on the inner side of the side wall 100. When installing the side bar 200, the locking rod 2200 at the front end of the side bar 200 needs to pass through the mounting hole 110 on the side bar 200 before engaging with the locking hole 1500. The size of the mounting hole 110 is close to the diameter of the front end of the side bar 200. When the front end of the side bar 200 is inserted into the mounting hole 110, the wall of the mounting hole 110 fits against the side bar 200, thereby limiting the side bar 200 from rotating downward and upward.

[0133] In addition to the above embodiments, a non-circular cross-section, such as a polygonal one, can also be used for the latch hole 1500 and latch rod 2200, which can restrict rotation by their own contours after engagement. However, installation requires the contours of the latch rod 2200 and latch hole 1500 to align, making installation more difficult. Furthermore, the rotation restriction is limited by the top corners of the contours, which, when worn, no longer function as a rotation restriction, resulting in a limited service life.

[0134] In addition, if Figure 2As shown, after the hanging portion 33 is set at the front end of the top pocket surface 31, the hanging portion 33 protrudes relative to the front end of the top pocket surface 31. At this time, it is necessary to avoid the formation of a gap between the front end of the top pocket surface 31 and the top cover 1 due to the setting of the hanging portion 33. Figure 3 and Figure 4 As shown, the position of the second rod body 21 needs to be set in the top cover 1 so that the hanging portion 33 extends into the top cover 1 and is connected to the second rod body 21. The position of the second rod body 21 in the top cover 1 is designed according to the structure of the hanging portion 33. It is necessary to ensure that when the hanging portion 33 is connected to the second rod body 21, the front end of the top pocket surface 31 still remains in contact with the side of the top cover 1.

[0135] Accordingly, on the basis of setting the side wall 100 at the rear end of the top cover 1, a passage for the hanging portion 33 to pass through needs to be reserved. Figure 3 As shown, in this embodiment, two side walls 100 are provided and are located on both sides of the top cover 1 , and there is a spacing between the two side walls 100 to form an installation channel 120 . The width of the installation channel 120 matches the width of the hanging portion 33 , and the hanging portion 33 can pass through the installation channel 120 .

[0136] Specifically, compared to the method of separately opening holes in the rear wall of the top cover 1 to form the mounting channel 120 and the aforementioned mounting hole 110, providing only the side walls 100 on either side of the top cover 1 and utilizing the spacing between the side walls 100 to form the mounting channel 120 reduces the weight of the top cover 1, and thus the weight of the entire grass collecting bag assembly 9. Furthermore, the lower portion of the mounting channel 120 is unobstructed, allowing the attachment portion 33 to more easily pass through the mounting channel 120 and attach to the second rod 21 during installation. After the bag body 3 is installed, the rear side of the side wall 100 aligns with the front end of the top bag surface 31 and the front end of the protruding notch 32 on the side bag surface 30.

[0137] In addition to the latching rod 2200 extending leftward and rightward at the front end of the side bar 200, the latching rod 2200 can also have various structural forms. For example, the latching rod 2200 can be formed by bending the front end of the side bar 200 outward 90° (not shown), thus forming an L-shaped structure with the side bar 200 and the latching rod 2200. Furthermore, since the side bar 200 needs to support the top pocket surface 31, the horizontal position of the side bar 200 affects the width or flatness of the top pocket surface 31. To ensure sufficient width and flatness of the top pocket surface 31, the side bar 200 needs to be as close as possible to the edge of the top cover 1. For these reasons, with this arrangement, the contact length between the latching rod 2200 and the latching hole 1500 is determined by the wall thickness of the top cover 1. A thicker top cover 1 wall increases the contact length and improves the connection stability, but also results in a heavier top cover 1. Conversely, a thinner top cover 1 wall shortens the contact length and reduces the connection stability.

[0138] To this end, in this embodiment, the design of the clamping rod 2200 is further optimized to ensure the connection stability while reducing the weight increase of the top cover 1. Specifically, Figures 2 to 4 As shown, in this embodiment, the clamping rod 2200 is set to be U-shaped, the first end of the clamping rod 2200 is connected to the end of the side rod 200, and the second end of the clamping rod 2200 is clamped with the clamping hole 1500.

[0139] In this embodiment, the opening of the U-shaped latching rod 2200 can face the outside of the side rod 200, and during installation, the rod section at the front end of the latching rod 2200 is inserted into the latching hole 1500. After the latching rod 2200 is set into a U-shape, the space created by the bending of the latching rod 2200 allows for a longer contact length between the rod section at the front end of the latching rod 2200 and the latching hole 1500. At the same time, the side rod 200 can also be close to the edge of the top cover 1, and the wall thickness of the top cover 1 does not need to be increased. The outer surface of the top cover 1 can also remain flat.

[0140] According to the above embodiment of the hanging portion 33, the hanging portion 33 can be hung on the second rod 21, and the second rod 21 is installed on the top cover 1, so there needs to be a space between the second rod 21 and the top cover 1 for the hanging portion 33 to hang. Figure 3 As shown, the second rod body 21 in this embodiment includes a connecting rod segment 212 and a sinking rod segment 211. The connecting rod segment 212 is connected to the second end of the top cover 1. There is a distance between the top of the sinking rod segment 211 and the top cover 1 to form a hanging channel. The hanging part 33 can be hung on the sinking rod segment 211 through the hanging channel.

[0141] Specifically, in this embodiment, the upper end surface of the sinking rod segment 211 of the second rod body 21 is lower than the upper end surface of the connecting rod segment 212. When the upper end surface of the connecting rod segment 212 is in contact with the top cover 1, a gap is formed between the upper end surface of the sinking rod segment 211 and the top cover 1. This gap serves as a hooking channel, and the hooking portion 33 at the front end of the top cover 31 can be hooked to the sinking rod segment 211 through the hooking channel. In this embodiment, the second rod body 21 can be mounted on the lower end surface of the top cover 1. To facilitate the connection between the connecting rod segment 212 and the top cover 1, the connecting rod segment 212 is preferably an inverted L-shaped, with its upper end being a horizontal section. The horizontal section can be relatively simply and stably mounted on the top cover 1.

[0142] In a specific installation method, such as Figure 2 and Figure 3 As shown, the support rod 2 further includes a pipe clamp pressing piece 4, which is provided with a pressing groove. The pipe clamp pressing piece 4 is detachably fixedly connected to the top cover 1, and the connecting rod segment 212 is pressed against the top cover 1 through the pressing groove. Specifically, the horizontal section of the connecting rod segment 212 is pressed against the top cover 1. The pipe clamp pressing piece 4 and the top cover 1 can be fixed by screws.

[0143] Since the installation of the second rod 21 requires the pipe clamping piece 4 and the screws need to be screwed in, the position of the second rod 21 on the top cover 1 needs to be in a set position, and the position of the pipe clamping piece 4 also needs to be in a set position. Therefore, in order to facilitate installation, Figure 3 As shown, in this embodiment, a rod body mounting groove 140 is provided at the second end of the top cover 1, and the rod body mounting groove 140 is used to accommodate and position the second rod body 21; a pressure piece mounting groove 130 is also provided on the top cover 1, and the pipe clamp pressure piece 4 is detachably fixed in the pressure piece mounting groove 130.

[0144] Specifically, in this embodiment, the length and width of the rod mounting groove 140 match the length and diameter of the second rod 21. This allows the rod mounting groove 140 to locate the second rod 21, specifically the connecting rod segment 212, on the second rod 21. The dimensions of the pressure piece mounting groove 130 match those of the pipe clamp pressure piece 4. This allows the pipe clamp pressure piece 4 to be positioned so that the threaded holes on the pipe clamp pressure piece 4 align with the threaded holes on the top cover 1, facilitating installation. Furthermore, to better compress the connecting rod segment 212, the pipe clamp pressure piece 4 is provided with an arcuate groove that matches the connecting rod segment 212.

[0145] In some environments, it is necessary to replace the pocket body 3 with a different volume. The difference in volume of the pocket body 3 is generally caused by the difference in length of the pocket body 3. In other words, it is necessary to replace the pocket body 3 with a different length. Accordingly, it is necessary to change the length of the portion of the support rod 2 extending from the rear of the top cover 1. The longer the length, the longer the pocket body 3 can be.

[0146] Based on this, in one embodiment, Figure 5 As shown, there are two or more connection positions 160 between the support rod 2 and the top cover 1 in the front-to-back direction. By changing the connection position 160, the length of the support rod 2 extending from the rear of the top cover 1 is changed to match pockets 3 of different sizes.

[0147] Specifically, taking the connection method in which the support rod 2 and the top cover 1 are engaged with each other via the first engaging portion 220 and the second engaging portion 150 as an example, two or more second engaging portions 150 may be provided in the front-to-back direction within the top cover 1. The support rod 2 may be connected to one of the second engaging portions 150 as required, thereby varying the length of the support rod 2 extending from the rear of the top cover 1 to accommodate pockets 3 of different sizes.

[0148] In another embodiment, Figure 6 As shown, the support rod 2 is retractable in the front-to-back direction to change the length of the support rod 2 extending out of the top cover 1 to match pocket bodies 3 of different sizes.

[0149] Specifically, the side rods 200 of the support rod 2 can be configured as retractable rods. By retracting the side rods 200, the length of the support rod 2 extending from the rear of the top cover 1 can be adjusted to accommodate pockets 3 of varying sizes. For example, the side rod 200 comprises an outer rod 2002 and an inner rod 2001, which are interconnected. The inner rod 2001 is provided with a plurality of axially disposed connection holes 7. A retractable push pin 8 or push bead is provided on the outer rod 2002. By pulling the outer rod 2002 or the inner rod 2001, the position of the push pin 8 or push bead is adjusted so that it engages with the connection holes 7 at different positions, thereby changing the length of the entire side rod 200. In this embodiment, the cooperation between the push bead and the connection hole 7 is used to lock the outer rod 2002 and the inner rod 2001. Of course, other locking methods are also possible, and this embodiment is not intended to limit such methods.

[0150] Since the bag body 3 is a flexible structure, in order to better support the grass inlet of the bag body 3, in this embodiment, the grass collecting bag assembly 9 also includes an inlet support frame 5, and the grass inlet 35 of the bag body 3 is provided with a buckle groove 34, and the inlet support frame 5 can be detachably buckled in the buckle groove 34.
