[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1 As shown, in this embodiment, a protective structure is provided, including a housing 2 disposed on a lawn mower body 1. Typically, the cutting device of a lawn mower is located on the underside of the body 1, contacting the lawn and vegetation on the ground to be cut, thereby trimming and cutting the lawn. However, there is a certain distance between the body 1 and the lawn, which results in the cutting device being exposed through the open area between the body 1 and the lawn. The housing 2 of the present application can be disposed on the lower edge of the peripheral side of the body 1, thereby enabling the housing 2 to cover or partially cover the open area of ​​the cutting device relative to the peripheral side of the body 1 to a certain extent, thereby achieving a certain degree of protective performance.

[0025] The housing 2 includes a handle housing 21 having a groove 211 and a protective plate 22. One side of the protective plate 22 is connected to the handle housing 21, and the other side extends away from the handle housing 21, thereby forming a protruding structure protruding from the handle housing 21. Figure 2 and Figure 3 The groove 211 of the handle housing 21 serves as a gripping area, allowing a user to reach into the groove 211 and lift the mower. Furthermore, it blocks a user's hand from approaching the cutting mechanism, improving protection. The groove 211 and the protective plate 22 work together to increase the overall protection area of ​​the protective element 2.

[0026] Due to the presence of the protective plate 22 , the size of the handle housing 21 can be adaptively adjusted. Without changing the overall protective area of ​​the protective element 2 , the size of the handle housing 21 can be reduced and the size of the protective plate 22 can be increased.

[0027] In summary of the above embodiments, the protective structure of the present application includes a housing 2 mounted on a lawn mower body 1. Housing 2 is positioned around the cutting mechanism of the lawn mower, thereby forming a barrier around the cutting mechanism and enhancing the protective effect of the lawn mower. Furthermore, housing 2 is provided with a recess 211, which serves as a gripping area, allowing a user to reach into recess 211 and lift the lawn mower.

[0028] In some embodiments, the housing 2 can be symmetrically arranged on the left and right sides of the body 1. Here, left and right are relative to the direction of travel of the body 1, that is, the forward direction is the front side, the backward direction is the rear side, and the other two sides correspond to the left and right sides of the body 1. In the related art, considering that the front and back sides of the body 1 are usually equipped with components such as push-pull rods, and the front and back sides of the body 1 are less structurally stable than the left and right sides, the housing 2 is arranged on the left and right sides of the body 1; of course, the housing 2 includes but is not limited to the left and right sides of the body 1. Without considering other factors, the protective member 2 can also be arranged at other locations around the body 1.

[0029] On the basis of the shell 2 being arranged on the left and right sides of the body 1, in conjunction with the existing lawn mower, the shell 2 can be further arranged between the front and rear wheels of the lawn mower; the front and rear wheels also have partial protection functions to a certain extent, which can prevent part of the structure on the cutting device from being directly exposed, which corresponds to the above-mentioned shell 2 partially covering the open area on the side of the cutting device relative to the body 1, and the other part of the cutting device can be covered by the front and rear wheels, thereby ensuring the overall protection performance of the cutting machine.

[0030] Taking into account the stability of the lawn mower when it is lifted by the protective structure, in some embodiments, the two shells 2 can be set on the same vertical plane as the center of gravity of the body 1 as much as possible; in other words, the center of gravity of the body 1 is close to or located on the vertical plane where the line connecting the shells 2 on both sides is located. However, it should be noted that since the shell 2 has a certain length, the line connecting the shells 2 on both sides is not a line, but a three-dimensional spatial structure. Therefore, the vertical projection of the center of gravity of the body 1 can fall on the three-dimensional spatial structure, so that when the lawn mower is lifted by the shell 2, the lawn mower will not tilt, etc., thereby ensuring the stability of the lawn mower when it is lifted.

[0031] In some embodiments, to facilitate insertion of a hand into the groove 211 structure, the opening of the groove 211 can be oriented toward the side or bottom of the vehicle body 1, that is, toward the exterior of the vehicle body or toward the ground. Furthermore, the opening width of the groove 211 in one direction, such as the horizontal direction, is greater than 40 mm to allow four fingers of a hand to fit into the groove 211 and ensure effective hand lifting. Of course, different opening widths of the groove 211 can also be selected based on actual circumstances, and this will not be detailed here.

[0032] In addition, please refer to Figure 2 and Figure 3The protective plate 22 surrounds the outer periphery of the notch in the handle housing 21. Specifically, the inner periphery of the protective plate 22 is connected to the handle housing 21, while the outer periphery of the protective plate 22 extends away from the handle housing 21. The raised structure extending from the protective plate 22 serves as the effective protective area of ​​the protective plate 22, which in turn determines the protective area of ​​the housing 2. The surface of the protective plate 22 is flush with the notch in the handle housing 21, ensuring a smooth transition between the two and preventing scratches caused by the raised notch in the handle housing 21.

[0033] Furthermore, the handle housing 21 and the protective plate 22 are integrally injection molded using a specific mold to form a one-piece housing 2. The housing 2 can be made of a plastic with a certain degree of hardness, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA), polycarbonate (PC), etc., or a metal with a certain degree of hardness, such as aluminum or stainless steel. Details will not be given here, as all such materials fall within the scope of protection of this application.

[0034] In some embodiments, the groove 211 on the handle shell 21 can be a square groove or a trapezoidal groove, and the two handle shells 21 located on both sides of the body 1 have their grooves 211 recessed in opposite directions, that is, in the design of the groove 211, the opening directions of the two opposite grooves 211 are opposite, and the recessed portion of one groove 211 faces the recessed portion of the other groove 211, so as to facilitate the insertion of a human hand therein; of course, the opening of the groove 211 faces the outside of the body 1, and at the same time, a wave groove matching the contour of the finger can be set in the groove 211 to improve the adaptability of the human hand to the handle shell 21.

[0035] The housing 2 is provided with fasteners for connection to the body 1, and the housing 2 can be removably connected to the body 1 via the fasteners. Specifically, the fasteners include fastening bolts provided on the handle housing 21. In other words, the handle housing 21 has fastening holes 212, and there are at least three fastening holes 212 distributed in a triangular pattern to improve the fastening effect of the fasteners. The fastening bolts can be inserted into the fastening holes 212, and the threaded rods of the fastening bolts pass through the fastening holes 212 and are threadedly connected to the body 1. Of course, the fastening bolts can also be provided on the protective plate 22. There are no further restrictions here. It is sufficient to ensure that the housing 2 can be stably and removably connected to the body 1.

[0036] In some embodiments, the inside of the groove 211 of the handle housing 21 can be covered with a soft rubber material, which can be rubber, etc., to improve the grip feel of the human hand and increase the friction between the human hand and the handle housing 21 to ensure stable lifting of the lawn mower.

[0037] In addition, please refer to Figure 2A reinforcing rib 23 connecting the protruding structure on the protective plate 22 and the handle housing 21 is provided at the intersection thereof, thereby improving the structural stability of the housing 2.

[0038] The present application also provides a lawn mower, comprising a body 1 and a cutting device arranged on the body 1, and further comprising a protective structure arranged on the left and right sides of the body 1, wherein the protective structure is the above-mentioned lawn mower protective structure.
