[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides an automatic lawn mower, including a casing 1, a docking casing 3 is slidably connected inside the casing 1, a protective frame 13 is fixedly connected to the inner wall of the docking casing 3, a servo motor 8 is fixedly connected inside the protective frame 13, the servo motor 8 is arranged in a vertical state, the output end of the servo motor 8 is fixedly connected to a cutting blade 9, the cutting blade 9 is located at the bottom of the casing 1, a double-headed rotating rod 5 is rotatably connected to the top of the docking casing 3, the other end of the double-headed rotating rod 5 is rotatably connected to a power cylinder 4, a support plate 2 is fixedly installed on the top of the casing 1, the power cylinder 4 is fixedly installed on the top of the support plate 2, a protrusion 6 is fixedly installed at the junction of the docking casing 3 and the double-headed rotating rod 5, the double-headed rotating rod 5 is located on both sides of the protrusion 6, the docking casing 3 is located below the support plate 2, and an opening 7 is provided at the junction of the support plate 2 and the protrusion 6.

[0025] The specific configuration and function of this embodiment are described in detail below. The housing 1 is used to accommodate various components required for the lawn mower. When in use, the servo motor 8 drives the cutting blade 9 to rotate. The cutting blade 9 is located at the bottom of the housing 1 as a whole. During the movement of the housing 1, the cutting blade 9 contacts the weeds to achieve the purpose of mowing. The servo motor 8 is connected to the docking housing 3 through the protective frame 13.

[0026] When the angle of the casing 1 changes due to the rise of the terrain, the power cylinder 4 is immediately started. The power cylinder 4 can be controlled by setting a sensor. When the piston rod in the power cylinder 4 is extended, it will push the double-headed rotating rod 5. Since the other end of the double-headed rotating rod 5 is rotatably connected to the protrusion 6, the double-headed rotating rod 5 will rotate with the connection point with the piston rod in the power cylinder 4 as the center of the circle, and the other end pushes the docking shell 3 downward through the protrusion 6, so that the cutting blade 9 is close to the ground, so as to ensure that the lawn mower can adapt to different terrains. The existence of the opening 7 provides sufficient space for the double-headed rotating rod 5 to move.

[0027] Embodiment 2

[0028] like Figure 4 As shown, a connecting rod 10 is fixedly installed at the edge of the docking shell 3, and the connecting rod 10 is slidably connected to the casing 1. An anti-slip groove 11 is provided at the intersection of the connecting rod 10 and the casing 1, and a limit block 12 is fixedly installed on the inner wall of the anti-slip groove 11.

[0029] The effect achieved by the entire embodiment is that the docking shell 3 is slidably connected to the casing 1 through the connecting rod 10. When the double-headed rotating rod 5 pushes the docking shell 3 to move downward, the connecting rod 10 can determine the movement route of the docking shell 3 to ensure that the docking shell 3 will only move in a straight line. The connecting rod 10 is connected to the casing 1 through the anti-slip groove 11 to ensure the stability of the docking shell 3. At the same time, a limit block 12 is also arranged inside the anti-slip groove 11 to limit the maximum movement range of the docking shell 3 and prevent the cutting blade 9 from being too close to the ground.

[0030] The use method and working principle of the device: during the movement of the housing 1, the servo motor 8 drives the cutting blade 9 to rotate, and the cutting blade 9 contacts the weeds to achieve the purpose of mowing. When the housing 1 changes its angle due to the rise of the terrain, the power cylinder 4 is immediately started, and the piston rod in the power cylinder 4 extends to push the double-headed rotating rod 5, and the double-headed rotating rod 5 pushes the docking housing 3 to move downward through the protrusion 6;

[0031] The docking shell 3 is slidably connected to the casing 1 through a connecting rod 10, which determines the moving route of the docking shell 3, and the connecting rod 10 is connected to the casing 1 through an anti-slip groove 11. At the same time, a limit block 12 is also arranged inside the anti-slip groove 11. The anti-slip groove 11 and the limit block 12 respectively limit the moving route and maximum moving range of the docking shell 3 to prevent the cutting blade 9 from being too close to the ground.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
