[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0033] In a preferred embodiment, see Figures 1 to 6 The present application provides a grass box structure 1 of a lawn mower, which is used to connect an external grass collection bag 2 to collect grass. The grass box structure 1 includes: a grass box cover 10; a limiting member 20, which is connected to the grass box cover 10; a support member 30, which is connected to the limiting member 20, and the limiting member 20 fixes the limiting support member 30 so that the support member 30 is located in a supporting position or a storage position; wherein the support member 30 has a certain elastic deformation relative to the limiting member 20, and the support member 30 is moved between the supporting position and the storage position through the elastic deformation of the support member 30.

[0034] As a preferred embodiment, the limiting member 20 includes: at least one mounting hole 21, and the limiting member 20 is connected to the grass box cover 10 through the mounting hole 21.

[0035] Specifically, there are two mounting holes 21 in the present application document, and the two mounting holes 21 are located diagonally on the limiter 20, and then the limiter 20 is fixed to the grass box cover 10 by passing a fastener through the two mounting holes 21. The fastener can be a bolt and nut structure. If the limiter 20 is to be removed from the grass box cover 10, it is only necessary to remove the fastener to remove the limiter 20 from the grass box cover 10, which is convenient to take.

[0036] At the same time, the support member 30 has a certain amount of elastic deformation, that is, the support member 30 has a certain elasticity and is rotatably connected to the limit member 20. Therefore, various rotation states of the support member 30 are completed relative to the limit member 20, and preferably, the support member 30 is a "J"-shaped support frame structure. Correspondingly, limit members 20 are provided on opposite sides of the grass box cover 10. The two limit members 20 are provided to correspond to the two support arms 31 of the "J"-shaped support frame, squeezing the two support arms 31 of the support frame to achieve the deformation of the support frame, and then completing the transformation of the support frame from the supporting position to the storage position, or from the storage position to the supporting position, so that the support member 30 can be stored and unfolded without disassembling the support member 30, so as to improve the transportation convenience of the lawn mower grass box and reduce the risk of missing or lost parts of the grass box during transportation.

[0037] As another preferred embodiment, see Figure 3 and Figure 4 The limiting member 20 also includes: a limiting boss 22, the limiting boss 22 and the main part of the limiting member 20 surround and define a retaining groove 23, when the support member 30 is in the storage position, the support arm 31 is placed in the retaining groove 23, and the retaining groove 23 limits the movement of the support member 30.

[0038] Further preferably, the limiting boss 22 is provided with a limiting surface 24 . When the support member 30 is located at the supporting position, the support arm 31 abuts against the limiting surface 24 to limit the support member 30 from moving toward the storage position.

[0039] Further preferably, the limiting boss 22 is also provided with a guide surface 25. When the support member 30 moves between the storage position and the supporting position, the support arm 31 moves in close contact with the guide surface 25. That is, the retaining groove 23 is arranged horizontally, and the limiting surface 24 is arranged vertically relative to the retaining groove 23. The plane where the retaining groove 23 is located smoothly transitions to the limiting surface 24 in an arc shape. Then, when the support member 30 changes from the supporting position to the storage position, the support arm 31 is squeezed so that the support arm 31 disengages from the limiting surface 24 and smoothly transitions into the retaining groove 23.

[0040] It is further preferred that the guide surface 25 is gradually tilted and retracted along the moving direction from the storage position to the supporting position. Specifically, there are two limit members 20, and they are located on opposite sides of the grass box cover 10. Therefore, the two guide surfaces 25 of the two limit members 20 are arranged opposite to each other, and along the moving direction from the storage position to the supporting position, the guide surfaces 25 on both sides are gradually tilted and retracted, so that when the support member 30 is restored from the storage position to the supporting position, the guide surface 25 plays a guiding role in the rebound reset of the support arm 31.

[0041] More preferably, the retaining member 20 further includes an insert portion 26, through which the grass box structure 1 is connected to the lawn mower. The insert portion 26 is provided with a plurality of slots 27, which are evenly spaced on the insert portion 26. Insertion holes 28 are provided along the distribution direction of the slots 27. The support member 30 further includes a connecting rod 32, which is inserted into the insertion hole 28 to connect with the retaining member 20. Specifically, the insert portion 26 is used to connect the grass box structure 1 to the shell body of the lawn mower to improve the stability of the grass box structure 1. The plurality of slots 27 provided on the insert portion 26 can effectively reduce the thickness of the insert portion 26 to prevent shrinkage.

[0042] It should be noted that, taking the support member 30 being in the storage position and rotating toward the supporting position as an example, when the support member 30 is in the storage position, the support arms 31 on both sides of the support member 30 are placed in the retaining groove 23 to limit the movement of the support member 30. When the support member 30 needs to be unfolded to connect the grass collecting bag 2, the support member 30 needs to be rotated from the storage position to the supporting position. It is necessary to squeeze the support arms 31 on both sides of the support member 30 so that the support arms 31 are disengaged from the retaining groove 23. At this time, the connecting rod 32 is still rotatably connected to the socket 28, and the connecting rod 32 will not fall out of the socket 28. Therefore, the support arm 31 will not interfere with the movement of the guide surface 25 during the rotation process. The support arm 31 can rotate in accordance with the guide surface 25 and enter the side of the limit surface 24 through the elastic rebound of the support member 30.

[0043] Preferably, a boss is provided at the connection position between the grass box cover 10 and the limiting member 20. When the support member 30 is in the supporting position, the limiting surface 24 can prevent the support member 30 from excessively tilting forward, while the boss can prevent the support member 30 from excessively tilting backward. The boss cooperates with the limiting surface 24 to ensure that the swing amplitude of the support member 30 will not be too large when it is in the supporting position, and is within a reasonable range, thereby making it easier to support the grass collecting bag 2.

[0044] For further optimization, see Figure 5 A pad 11 is provided at the bottom of the grass box cover 10, and a dustproof cloth 12 is fixedly provided on the pad 11 to prevent the grass residue in the grass collecting bag 2 from flying out.

[0045] For further optimization, see Figure 5 The side wall edge of the grass box cover 10 is provided with an inner side wall 13 and an outer side wall 14, the inner side wall 13 and the outer side wall 14 are surrounded to form a card slot 15, and the outer side wall 14 is provided with a hook 16 facing the inner side wall 13; wherein, when the grass collecting bag 2 is connected to the grass box cover 10, the card slot 15 cooperates with the buckle to press the edge of the grass collecting bag 2 for fastening.

[0046] In a specific assembly method, a leather buckle is provided on the top edge of the grass collecting bag 2, which can be connected to the hook 16, and the card slot 15 can simultaneously press and fix the edge of the grass collecting bag 2, further improving the stability of the grass collecting bag 2 when assembled to the grass box cover 10.

[0047] Furthermore, the straw box cover 10 is integrally formed, and a handle is provided on the straw box cover 10, and the handle is not higher than the surface of the straw box cover 10, so as to reduce the volume and improve space utilization during transportation.

[0048] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application.
