[0026] Please refer to Figures 1 and 2 together. Figure 1 is a structural schematic diagram of the walking device 100 provided in an embodiment of the present application at a first perspective; Figure 2 is a structural schematic diagram of the walking device 100 provided in an embodiment of the present application at a second perspective. This embodiment provides a walking device 100. The walking device 100 can be configured as a mowing device, a harvesting device, and the like. For example, in this embodiment, the structure of the walking device 100 is described by taking the walking device 100 configured as a mowing device as an example. The walking device 100 includes a mobile chassis 10 and a cutter disc 20 mounted on the mobile chassis 10. The cutter disc 20 is used to mow the lawn.

[0027] The mobile chassis 10 includes a chassis body 11, a bridge structure 12 and a protective member 13. The chassis body 11 includes a main body 111 and a connecting portion 112 connected to the main body 111. Along the width direction X of the mobile chassis 10, the width of the main body 111 is greater than the width of the connecting portion 112. The bridge structure 12 is connected to the connecting portion 112. The bridge structure 12 is protruded relative to the connecting portion 112 along the width direction of the mobile chassis 10. The bridge structure 12 and the main body 111 are spaced apart and a gap 101 is formed between them. The protective member 13 is connected to the main body 111 and is located between the main body 111 and the bridge structure 12. In this embodiment, the protective member 13 is located between the bridge structure 12 and the main body 111, effectively reducing the gap between the main body 111 and the bridge structure 12. The protective member 13 can stop external foreign objects and prevent them from entering the gap 101 between the main body 111 and the axle structure 12, thereby preventing foreign objects from obstructing the travel of the walking device 100 and damaging the walking device 100, thereby reducing the maintenance and repair costs of the walking device 100 and improving the stability and reliability of the walking device 100. In addition, the protective member 13 can also stop external hard objects or the user's hands when the cutter head 20 is working, preventing hard objects or the user's hands from extending into the working area of ​​the cutter head 20, thereby avoiding damage to the cutter head 20 or personal injury, thereby improving the safety of the walking device 100. When carrying the walking device 100, the protective member 13 can also serve as a handle, providing a fulcrum for the user or the extraction machine, thereby facilitating the transportation of the walking device 100.

[0028] The width direction X of the mobile chassis 10 is parallel to the axial direction of the axle 121. For a clearer description, in this application, the X-axis direction is defined as the width direction of the mobile chassis 10. The width direction of the mobile chassis 10 can be customized based on the specific structure of the product and the perspective of the drawings, and is not specifically limited in this application.

[0029] In this embodiment, a plurality of protective members 13 are provided. Protective members 13 are provided on both sides of the main body 111 along the width direction X of the mobile chassis 10. The outer side walls of the protective members 13 are provided flush with the outer side walls of the main body 111 to improve the passability of the walking device 100 and avoid the problem of the protective members 13 and external foreign objects being blocked when the walking device 100 is traveling. The outer side walls of the protective members 13 refer to the wall surface of the protective member 13 on the side away from the connecting portion 112 along the width direction X of the mobile chassis 10, and the outer side walls of the main body 111 refer to the side wall surfaces of the main body 111 on the opposite sides along the width direction X of the mobile chassis 10.

[0030] The axle structure 12 includes an axle 121 and a wheel 122. The axle 121 is connected to the connecting portion 112, and the end of the axle 121 is protruded relative to the connecting portion 112 along the width direction X of the mobile chassis 10. The wheel 122 is connected to the end of the axle 121 away from the connecting portion 112. The wheel 122 is spaced apart from the main body 111, and the guard 13 is located between the main body 111 and the wheel 122. The side of the wheel 122 away from the connecting portion 112 is protruded relative to the guard 13 along the width direction X of the mobile chassis 10. The cutter disc 20 is mounted on the main body 111. The distance between the cutter disc 20 and the axle structure 12 is greater than the distance between the guard 13 and the axle structure 12. It is understandable that there is a gap between the guard 13 and the wheel 122 to prevent friction between the wheel 122 and the guard 13 when the wheel 122 rotates, resulting in obstructed rotation. Therefore, an external foreign object or a user's hand may still accidentally enter the gap 101 from the side and front of the walking device 100. After the external foreign object or the user's hand accidentally enters the gap 101 from the side and front of the walking device 100, the foreign object or hand will move to the vicinity of the axle 121, that is, to a position in the gap 101 away from the cutter head 20, thereby further preventing damage to the cutter head 20 or personal injury. When an external foreign object or the user's hand approaches the walking device 100 from the side and rear, since the wheel 122 is protruding relative to the protective member 13, the wheel 122 can stop the foreign object or the user's hand, thereby preventing the foreign object or the user's hand from entering the gap 101 and ensuring the safe use of the walking device 100.

[0031] In some embodiments, the protective member 13 protrudes from the bottom of the main body 111 at least partially toward the ground. The distance between the protective member 13 and the ground is smaller than the distance between the main body 111 and the ground. When the walking device 100 encounters a hard obstacle on the ground (such as a stone or a tree stump), the protective member 13 can stop the hard obstacle and prevent the hard obstacle from entering the side of the main body 111 close to the ground, thereby preventing the cutter disc 20 from colliding with the hard obstacle and avoiding damage to the cutter disc 20. The protective member 13 can also prevent the user's hand from extending from the side of the walking device 100 close to the ground to the position of the cutter disc 20, thereby preventing the user's hand from being scratched by the cutter disc 20.

[0032] Please refer to Figures 1, 2 and 3 together. The protective member 13 includes a connecting plate 131 and a first side plate 1321. The connecting plate 131 is connected to the side of the main body 111 facing the ground. The first side plate 1321 is connected to the side of the connecting plate 131 close to the axle structure 12 and extends toward the axle structure 12. The connecting plate 131 can be integrally formed with the main body 111, or the connecting plate 131 can be separated from the main body 111 and fixedly connected to the main body 111 by welding, clamping, melting, bonding, etc. The first side plate 1321 can be integrally formed with the connecting plate 131, or the first side plate 1321 can be separated from the connecting plate 131 and fixedly connected to the connecting plate 131 by welding, clamping, melting, bonding, etc. A guide portion 1311 is provided on the side of the connecting plate 131 facing the front of the mobile chassis 10. The guide portion 1311 is located on the side of the connecting plate 131 facing away from the axle structure 12. Part of the connecting plate 131 extends to the side of the main body 111 along the width direction X of the mobile chassis 10. The side of the connecting plate 131 facing away from the axle structure 12 is provided with an inclined surface inclined toward the axle structure 12, forming the guide portion 1311. When the walking device 100 encounters an obstacle, the guiding effect of the guide portion 1311 allows the obstacle to slide to the side of the guard 13 facing the ground, thereby preventing the guard 13 from interfering with the obstacle and causing travel obstruction of the walking device 100, thereby ensuring the travel performance of the walking device 100.

[0033] The protective member 13 also includes a second side plate 1321. The second side plate 1321 is connected to the side of the connecting plate 131 close to the axle structure 12, and extends in the direction of the axle structure 12. The second side plate 1321 is spaced apart from the first side plate 1322. The second side plate 1321 is located on the side of the first side plate 1322 close to the connecting portion 112. The second side plate 1321 is tilted in the direction of the first side plate 1322. The protective member 13 as a whole is roughly in the shape of a right-angled trapezoid. After an external foreign object or a user's hand accidentally enters the gap 101, the second side plate 1321 can play a guiding role, making it easier for the foreign object or the user's hand to slide out of the gap between the protective member 13 and the wheel 122, thereby facilitating the separation of the walking device 100 from the foreign object or the user's hand.

[0034] The protective member 13 also includes a reinforcing plate 133. The reinforcing plate 133 is located between the first side plate 1322 and the second side plate 1321 and is connected to the first side plate 1322 and the second side plate 1321, respectively. The reinforcing plate 133 is used to support the first side plate 1322 and the second side plate 1321, thereby enhancing the structural stability of the protective member 13 and preventing the protective member 13 from bending or deformation.

[0035] The protective member 13 also includes a top plate 134. The top plate 134 is located on the side of the first side plate 1322 and the second side plate 1321 away from the ground. The connection plate 131, the first side plate 1322, the second side plate 1321, and the top plate 134 enclose a cavity structure. This not only improves the overall structural strength of the protective member 13, but also reduces the weight of the protective member 13 and the overall mass of the walking device 100, thereby facilitating a lightweight design of the walking device 100. The protective member 13 and the main body 111 can be integrally formed to simplify the production process of the mobile chassis 10 and reduce costs.

[0036] The corners of the end of the protective member 13 away from the main body 111 are rounded to prevent the protective member 13 from scratching the user's hands. There is an arc transition between the first side panel 1322 and the top panel 134, and between the second side panel 1321 and the top panel 134. Among them, there can be multiple reinforcing plates 133, and the multiple reinforcing plates 133 are spaced apart. One of the multiple reinforcing plates 133 is located at the end of the first side panel 1322 and the second side panel 1321 away from the connecting plate 131, and the reinforcing plate 133 is respectively provided with an arc transition with the first side panel 1322 and the second side panel 1321.

[0037] Referring to Figure 4 , in some embodiments, the protective member 13 is rotatably connected to the main body 111. The protective member 13 can rotate relative to the main body 111 in a direction away from the connection portion 112. That is, the protective member 13 can rotate outward relative to the mobile chassis 10. If a foreign object or a user's hand accidentally enters the gap 101, the rotation of the protective member 13 can promptly remove the foreign object or the user's hand from the gap 101, thereby ensuring safe use of the walking device 100.

[0038] Specifically, the mobile chassis 10 may include a rotating shaft 141 and a stopper 142. The rotating shaft 141 and the stopper 142 are both mounted on the main body 111. The protective member 13 is passed through the rotating shaft 141 and can rotate around the rotating shaft 141. The stopper 142 is located on the side of the protective member 13 close to the connecting portion 112 along the width direction X of the mobile chassis 10. The stopper 142 can stop the protective member 13 and prevent the protective member 13 from rotating toward the connecting portion 112. When the stopper 142 stops the protective member 13, the outer wall of the protective member 13 is flush with the outer wall of the main body 111.

[0039] In some embodiments, the mobile chassis 10 further includes a reset member (not shown) disposed on the main body 111. The reset member is connected to the protective member 13 and is used to reset the protective member 13. When the protective member 13 is reset, the protective member 13 can abut against the stopper 142.

[0040] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and such modifications or substitutions should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
