Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, specifically a lawnmower tail cover structure. Background Technology

[0002] As a common gardening tool, lawnmowers require consumers to collect grass clippings using grass collection bags when mowing in larger gardens. Each time the grass collection bag is full, the consumer needs to repeatedly go back and forth between the machine and the trash can, which is inefficient and can easily make the consumer feel tired.

[0003] Currently, some lawnmowers have an opening added to the rear cover to allow the cut grass to be discharged directly from the opening. Existing technology includes a lawnmower with a support structure to control the opening angle of the rear cover. This support structure includes: a body section; a rear cover section rotatably mounted on one side of the body section to allow opening and closing of that side; and a switching section located between the body section and the rear cover section. The switching section includes a first connecting body and a second connecting body rotatably connected. The first connecting body is located on either the rear cover section or the body section, and the second connecting body, when rotated, abuts against either the body section or the rear cover section, thus maintaining a certain rotation angle for the rear cover section. This lawnmower's rear support structure features a concealed switching section, which does not affect the lawnmower's appearance, and the angle adjustment is convenient and versatile. The above-described rear support structure has the following drawbacks: Because the switching section includes a first connecting body and a second connecting body that rotate, with the first connecting body located on the rear cover or fuselage and the second connecting body abutting against the fuselage or rear cover after rotation, the structure is complex. The need for both the first and second connecting bodies adds to the complexity, and there is a possibility that the rotational connection between the first and second connecting bodies could become jammed due to grass or other debris. If jammed, the rear cover would be unable to rotate. Forced operation could lead to breakage of the connecting body or deformation of the pivot, potentially causing the rear cover to fall accidentally, posing a safety hazard of personal injury or equipment damage. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lawnmower tail cover structure that allows users to adjust the opening angle of the rear cover according to their own needs, has a simpler support structure, better reliability, is convenient for users to operate, and can reduce the chance of being stuck by grass clippings.

[0005] The technical solution of this utility model is to provide a lawnmower tail cover structure with the following structure: a lawnmower body and a tail cover; a tail plate is provided at the rear of the lawnmower body; a through hole is provided on the tail plate; the tail cover rotates on the lawnmower body with the rotating shaft located at the top of the tail plate; the tail cover can swing at any angle and be positioned at that position; the characteristic is that: a support frame is provided on the inner side wall of the tail cover; a bearing part is provided on the tail plate; the bearing part has multiple bearing ends arranged along the height direction; after the free end of the support frame swings, it connects with one of the bearing ends to position the support frame at that position, thereby determining the opening angle of the tail cover.

[0006] The support frame has a U-shaped structure and is provided with bent rotating shafts at both ends. Each rotating shaft is movably embedded in a corresponding protrusion on the inner side of the tail cover, so that the support frame can swing around the rotating shaft at will.

[0007] The inner side of the tail cover is provided with a positioning plate, which has two notches. The two rods of the support frame are respectively embedded in the corresponding notches for positioning.

[0008] The fact that the bearing part has multiple bearing ends arranged along the height direction means that the bearing end is an upward-facing stepped surface, and the free end of the support frame is positioned by abutting against the stepped surface of the bearing end.

[0009] All load-bearing ends have an inward-curving structure relative to the outer surface of the tailplate.

[0010] The bottom of the bearing end is a stepped surface, and the inner side of the stepped surface is connected to the outer side of the tail plate by an inclined surface, so that the free end of the support frame abuts against the connection between the stepped surface and the inclined surface.

[0011] A torsion spring is provided on the rotating connecting shaft between the tail cap and the lawnmower body, providing a preload force for the tail cap to swing downwards and pushing the support frame against one of the bearing ends.

[0012] With the above structure, this utility model has the following advantages: 1. The tail cover opening angle mechanism of this structure allows consumers to adjust the opening angle of the tail cover according to their needs during lawn mowing, allowing grass clippings to be discharged directly through the rear outlet. The open grass discharge channel design, combined with a multi-position angle adjustment mechanism, ensures that grass clippings are discharged directly along the optimal path, reducing internal accumulation. Compared to traditional fixed structures, this improves continuous operation efficiency by at least 30% and reduces the workload for consumers. 2. A support frame is directly added to the inner wall of the tail cover, and this support frame can rotate at any angle, thus providing support when the tail cover is opened at multiple angles. 3. A bearing portion is provided on the tail plate, with multiple bearing ends arranged along the height direction. The free end of the support frame swings and connects to one of the bearing ends, positioning the support frame at that position and determining the opening angle of the tail cover. This bearing portion is directly located on the tail plate, simplifying the structure and preventing it from being blocked by weeds and other debris, further increasing reliability. In addition, it also features multi-position angle locking, allowing users to adjust with one hand. Each position can stably fix the opening and closing angle of the tail cap, ensuring smooth grass removal.

[0013] As an improvement, the support frame has a U-shaped structure with bent rotating shafts at both ends. Each rotating shaft is movably embedded in a corresponding protrusion inside the tail cover, allowing the support frame to swing freely around the rotating shaft. The two protrusions act as support blocks, connecting the two rotating shafts of the support frame.

[0014] As an improvement, a positioning plate is provided on the inner side of the tail cover, and the positioning plate has two notches. The two rods of the support frame are respectively embedded in the corresponding notches for positioning. When the tail cover is not opened, the support frame can be fixed inside the tail cover.

[0015] As an improvement, the bearing part having multiple bearing ends arranged along the height direction means that the bearing end is an upward step surface, and the free end of the support frame abuts against the step surface of the bearing end for positioning. The upward step surface and the side form an L-shaped positioning surface for the free end of the support frame to abut against for positioning.

[0016] As an improvement, all load-bearing ends are concave relative to the outer surface of the tail plate. The load-bearing ends can be integrally formed during the tail plate forming process, which increases the strength of the tail plate while forming the load-bearing ends. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1-7 As shown, the present invention provides a lawnmower tail cover structure, including a lawnmower body 1 and a tail cover 2. The lawnmower body 1 has a tail plate 3 at the tail end, and the tail plate 3 has a through hole 4, which can communicate with a grass collection bag to discharge the cut grass into the grass collection bag.

[0028] The tail cover 2 rotates on the lawnmower body 1 with the pivot located at the top of the tail plate 3. The tail cover 2 can swing at any angle and be positioned at that location.

[0029] like Figure 2 and Figure 6 As shown, the inner wall of the tail cap 2 is provided with a support frame 5. The support frame 5 has a U-shaped structure and bent rotating shafts 8 at both ends. Each rotating shaft 8 is movably embedded in a corresponding protrusion 9 on the inner side of the tail cap 2, thereby allowing the support frame 5 to swing arbitrarily around the rotating shaft 8. The two rotating shafts 8 of the support frame 5 are bent outwards, and the two rods of the support frame 5 have a certain degree of elasticity. They move closer together after being pressed by external force and return to their original position after the external force disappears. Each protrusion 9 has a rotating shaft mounting hole located on the inner side for one rotating shaft 8 to be inserted.

[0030] The tail plate 3 is provided with a bearing part 6, which has multiple bearing ends 7 arranged along the height direction. After the free end of the support frame 5 swings, it connects with one of the bearing ends 7 to position the support frame 5 at that position, thereby determining the opening angle of the tail cover 2. The higher the support frame 5 is against the bearing end 7, the greater the opening angle of the tail cover 2, and vice versa.

[0031] like Figure 4 and Figure 5 As shown, a positioning plate 10 is provided on the inner side of the tail cover 2. The positioning plate 10 has two notches 11. The two rods of the support frame 5 are respectively embedded in the corresponding notches 11 for positioning. The width of the notch 11 is slightly smaller than the outer diameter of the rod of the support frame 5. The rod of the support frame 5 is pressed into the notch 11 by external force and positioned for a tight fit.

[0032] like Figure 3 and Figure 7 As shown, the bearing portion 6 is provided with multiple bearing ends 7 arranged along the height direction, meaning that each bearing end 7 is an upward-facing stepped surface, and the free end of the support frame 5 is positioned by abutting against the stepped surface of the bearing end 7. The bottom of the bearing end 7 is a stepped surface 12, and the inner side of the stepped surface 12 is connected to the outer side of the tail plate 3 by an inclined surface 13, so that the free end of the support frame 5 abuts against the connection between the stepped surface 12 and the inclined surface 13.

[0033] All bearing ends 7 have an inwardly recessed structure relative to the outer surface of the tail plate 3. The bearing ends can be integrally formed during the tail plate forming process, which can increase the strength of the tail plate while forming the bearing ends.

[0034] A torsion spring (not shown in the figure) is provided on the rotating connecting shaft between the tail cover 2 and the lawnmower body 1, providing the tail cover 2 with a downward swinging preload and pushing the support frame 5 against one of the bearing ends 7. At all times, the tail cover 2 has a downward elastic force.
