[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] The core of the utility model is to provide a lawn mower, which has an improved mowing ability under the action of a grass combing member and will not produce a hard collision when encountering an obstacle.
[0032] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application.
[0033] The present application provides a lawn mower comprising: a body, a mobile module, a mowing mechanism and a grass combing element;
[0034] The moving module is arranged on the body and is used to drive the lawn mower to move;
[0035] The mowing mechanism is arranged on the machine body and is used to perform the mowing task;
[0036] The grass combing piece is arranged on the machine body, and in the forward direction of the lawn mower, the grass combing piece is located in front of the mowing mechanism, and the grass combing piece is movable relative to the machine body.
[0037] For details, please refer to the attached Figure 3The lawn mower moves in a specified direction under the action of the mobile module. A mowing mechanism and a grass combing piece are provided on the body of the lawn mower. The grass combing piece is provided in the forward direction of the lawn mower, and the grass combing piece is located in front of the mowing mechanism. The fallen and bent grass can be lifted up by the grass combing piece. During the movement of the lawn mower, the grass is first lifted up by the grass combing piece, and then the lifted grass is cut by the mowing mechanism, which can improve the mowing effect. In addition, the grass combing piece can be movable relative to the body. When the lawn mower encounters an obstacle during movement, the obstacle contacts the grass combing piece, and the grass combing piece can move to avoid hard collision between the grass combing piece and the obstacle, prevent damage to the grass combing piece, and extend the service life of the equipment.
[0038] Based on the above embodiment, the lawn mower also includes an axle 3 and a mounting seat 4, the wheel is arranged on the axle 3, the grass combing piece is fixedly connected to the axle 3, the axle 3 is rotatably connected to the mounting seat 4, and the mounting seat 4 is installed on the body.
[0039] Specifically, the axle 3 is rotatably mounted on the mounting base 4, the wheels are mounted on both sides of the axle 3, and the axle 3 is rotatably connected to the mounting base 4. Please refer to the attached Figure 2 The axle 3 is fixedly connected to the grass-combing piece. When the axle 3 rotates, it can drive the grass-combing piece to produce a height difference in the vertical direction. When the grass-combing piece is subjected to stress from an obstacle, it can drive the axle 3 to rotate, thereby avoiding hard collision.
[0040] On the basis of the above embodiment, the mounting base 4 can move up and down along the fuselage.
[0041] Specifically, the mounting seat 4 and the base of the lawn mower can move relative to each other in the vertical direction. During the movement of the lawn mower, when the front of the combing piece contacts an obstacle, the obstacle will generate stress on the combing piece in the direction toward the upper and rear of the combing piece. The combing piece can be adjusted in height in the vertical direction to buffer the upward stress of the obstacle. The axle 3 and the mounting seat 4 can be rotatably connected to buffer the backward stress.
[0042] In some embodiments, the grass combing component includes: a base 1; a plurality of comb teeth 2, which are evenly distributed on the side of the base 1 close to the ground, and the comb teeth 2 are used to contact the grass in front of the lawn mower when the lawn mower moves.
[0043] For details, please refer to the attached Figure 1 The base 1 is preferably a U-shaped structure, and a plurality of comb teeth 2 are arranged on the side of the base 1 close to the ground. When the lawn mower moves, the comb teeth 2 can lift up the bent and fallen grass. It should be noted here that the grass roots are buried in the ground, and the grass tips grow toward the ground under the action of external force, forming an inverted U-shaped structure. The comb teeth 2 can be inserted into the U-shaped structure and comb the U-shaped structure by moving, which is convenient for the mowing mechanism to weed.
[0044] On the basis of the above embodiment, the comb teeth 2 are provided with a forward convex structure 201 at the front end in the forward direction of the lawn mower. The forward convex structure 201 protrudes from the base 1 in the forward direction of the lawn mower.
[0045] Specifically, the convex structure 201 arranged at the front end of the comb teeth 2 is smaller in size, which is conducive to combing grass. When the lawn mower moves forward, the convex structure 201 protrudes from the base 1, and the grass is combed after the convex structure 201 passes through the U-shaped grass. The end of the convex structure 201 is pointed or round, which can more smoothly comb the fallen and bent grass.
[0046] On the basis of the above embodiment, the forward convex structure is provided with a transition slope 202. In the forward direction of the lawn mower, the front end height of the transition slope 202 is higher than the rear end height.
[0047] Specifically, the forward convex structure 201 smoothly transitions to the rear end through the transition slope 202. Generally speaking, when the grass combing piece encounters an obstacle, the transition slope 202 first contacts the obstacle. During the movement of the lawn mower, the obstacle can move backward along the transition slope 202 and gradually lift up the base 1, thereby preventing the comb teeth 2 from breaking due to a hard collision with the obstacle.
[0048] On the basis of the above embodiment, the plurality of protruding structures 201 located on the side of the base 1 are all moved closer to the protruding structure 201 located in the middle of the base 1 .
[0049] Specifically, when the number of comb teeth 2 is an odd number, the comb teeth 2 located in the middle of the base 1 are arranged parallel to the movement direction of the lawn mower, and the protruding structures 201 of the comb teeth 2 on both sides are close to the comb teeth 2 in the middle. When the number of comb teeth 2 is an even number, with the middle position of the base 1 as a reference, the protruding structures 201 of the comb teeth 2 on both sides are close to the middle position. When the lawn mower faces a ball of fallen and bent grass, as the lawn mower moves, multiple comb teeth 2 can lift up and comb the grass ball to facilitate subsequent weeding by the mowing mechanism.
[0050] In some embodiments, the axle 3 and the grass-combing element form an annular structure, and the body includes a bottom shell, which passes through the annular structure and a movable space is provided between the bottom shell and the annular structure.
[0051] Specifically, the annular structure formed by the axle 3 and the grass-combing piece is regarded as a whole, the bottom shell of the fuselage passes through the annular structure, and a movable space is provided between the bottom shell and the annular structure. Under normal conditions, the upper end of the annular structure is pressed on the bottom shell. When encountering an obstacle, the annular structure can rotate relative to the mounting seat 4 to adjust the vertical height of the grass-combing piece to avoid hard collision.
[0052] What needs to be further explained about the range of motion of the ring assembly is that the horizontal height of the base 1 is lower to be closer to the ground, so that the grass caused by external force can be lifted up. The purpose of the mowing mechanism is to cut the part of the grass that is too high, so it should maintain a certain distance from the ground. Therefore, the mowing mechanism should be slightly higher than the horizontal height of the base 1. Generally speaking, the highest position of the base 1 should be slightly lower than the mowing mechanism. During the movement of the lawn mower, for smaller obstacles, the base 1 can be raised to avoid the obstacle, and the obstacle will not collide with the mowing mechanism. For larger obstacles, especially when the size of the obstacle is greater than the distance between the mowing mechanism and the ground, it will still cause a hard collision between the base 1 and the obstacle, preventing the lawn mower from moving forward. In this case, although certain collision damage will be caused to the base 1, the loss caused is smaller than that of damaging the mowing mechanism. However, in the above situation, when the size of the obstacle is greater than the movable range of the base 1, the operator operating the lawn mower can intuitively see the obstacle and can avoid collision by changing the running trajectory of the lawn mower.
[0053] On the basis of the above embodiment, the base 1 and the axle 3 are detachably connected.
[0054] Specifically, the position between the base 1 and the axle 3 is fixed, but the two are preferably detachably connected. During the operation of the lawn mower, the method to avoid hard collision between the grass combing piece and the obstacle is to make the obstacle move relative to the comb teeth 2 of the grass combing piece and lift the grass combing piece. There must be friction between the obstacle and the grass combing piece during the whole process. After being used for more than a certain period of time, that is, after multiple frictions, it is easy to cause structural damage. In addition, during the weeding process, the moisture in the grass plants will splash onto the surface of the base 1 and the comb teeth 2, which is also easy to reduce the service life. Therefore, the base 1 and the axle 3 are set to be detachably connected to facilitate its disassembly and replacement, thereby reducing costs.
[0055] Optionally, the base 1 and the comb teeth 2 may be an integrally formed plastic structure, which can significantly reduce costs.
[0056] In some embodiments, a plurality of comb teeth 2 are arranged along the axial direction of the axle 3 .
[0057] Specifically, the comb teeth 2 are evenly arranged along the axial direction of the axle 3. Generally speaking, the distance between the two comb teeth 2 on the two sides should be greater than or equal to the lateral dimension of the mowing mechanism. For this application, the mowing mechanism is a mowing disk, and the distance between the two comb teeth 2 on the two sides should be greater than or equal to the diameter of the mowing disk to ensure that the grass cut by the mowing component is all grass combed by the comb teeth 2.
[0058] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
