Description

Technical Field

[0001] The utility model relates to the technical field of lawn mowing robots, and more specifically to an anti-collision lawn mowing robot. Background Art

[0002] With the gradual improvement of production and modernization of life, lawn mowing has gradually developed from traditional hand-push lawn mowers to lawn mowing robots to replace manual labor for heavy work. Robotic lawn mowers have automatic walking functions and can autonomously complete the work of mowing the lawn without direct human control and operation. Due to the high cost of robots and the complex working environment, it is necessary to add anti-collision structures to avoid damage to the robots. However, existing anti-collision lawn mowing robots only have the function of anti-collision or reducing impact force. Therefore, when colliding with an object, the robot is blocked by the collision object and cannot correct the robot's forward route in time, which causes the robot to fail to work normally.

[0003] According to the Chinese utility model publication number CN217591568U, a lawn mower robot with an anti-collision structure includes a lawn mower body, at least one anti-collision bracket and at least one anti-collision component, wherein the anti-collision bracket is fixedly arranged on the lawn mower body. The lawn mower robot with an anti-collision structure described in the utility model has anti-collision plates arranged around it. Once the planned path is exceeded, the anti-collision plates first contact with other building bodies, which can prevent the lawn mower robot from colliding. It is particularly suitable for lawn mowing and maintenance in places such as family courtyards and public green spaces. However, this setting only has the function of preventing collision or reducing impact force, so that when colliding with an object, the robot is blocked by the collision object and cannot correct the robot's forward route in time, which leads to the robot being unable to work normally. Therefore, in view of this problem, how to design an anti-collision lawn mower robot has become a problem that we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an anti-collision lawn mowing robot. By setting a correction wheel, when the correction wheel on the left side collides with an object, the correction wheel rotates to drive the machine body to move to one side of the object, or push the object to one side of the machine body, and the same is true for the right side, thereby causing the object to deviate from the forward direction of the machine body, and then correcting the forward direction of the machine body to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-collision lawn mowing robot comprises a body, wherein the body is rotatably connected to a first shaft column inside, a first driven pulley is fixedly installed on the outer side of the first shaft column, a first belt is sleeved on the outer side of the first driven pulley, the body is rotatably connected to a second shaft column inside, a first driving pulley is fixedly installed on the outer side of the second shaft column, the first belt is sleeved on the outer side of the first driving pulley, a motor is fixedly installed inside the body, the second shaft column is fixedly installed on the output end of the motor, a correction wheel is fixedly installed on the outer side of the first shaft column, the correction wheel is rotatably connected to the inside of the body, the body is rotatably connected to a second driven pulley inside, and a second driving pulley is fixedly installed on the outer side of the second shaft column.

[0006] In a preferred embodiment, a second belt is sleeved on the outer side of the second driving pulley, and the second belt is sleeved on the outer side of the second driven pulley.

[0007] In a preferred embodiment, a transmission disc is fixedly mounted on the top of the second driven pulley, and a first connecting rod is rotatably connected to the top of the transmission disc.

[0008] In a preferred embodiment, a fixing rod is fixedly installed on the top of the first connecting rod, a correction plate is fixedly installed on one end of the fixing rod, and the correction plate is slidably connected to the inside of the machine body.

[0009] In a preferred embodiment, a second connecting rod is fixedly mounted on the top of the fixing rod, and a sliding block is fixedly mounted on the top of the second connecting rod.

[0010] In a preferred embodiment, a sliding limit frame is sleeved on the outer side of the sliding block, and a sliding plate is fixedly mounted on one side of the sliding limit frame.

[0011] In a preferred embodiment, a fixed limiting frame is fixedly installed inside the body, and the slide plate is slidably connected to the inner side of the fixed limiting frame.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model is provided with a correction wheel. When the robot collides with an object during operation, the correction wheel protrudes from the body, so that the object will contact the correction wheel first, thereby avoiding damage to the body. The rotation of the correction wheel will drive the body to move to one side of the object, or push the object to one side of the body, and the same is true for the right side, thereby correcting the forward direction of the body, thereby avoiding the phenomenon that the object blocks the forward movement of the body and causes the body to fail to operate normally;

[0014] 2. The utility model provides a correction paddle. When the correction paddle performs a left circular slide, the correction paddle protrudes from the machine body and is pushed to one side during movement. Therefore, when the machine body collides head-on with an obstacle, the correction ability of the correction wheel is reduced. The movement of the correction paddle can assist the correction wheel in correcting the position of the machine body, thereby achieving the effect of being able to correct the machine body when a head-on collision occurs and assisting the correction wheel in correcting the machine body.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1As shown, an anti-collision lawn mowing robot according to an embodiment of the utility model comprises a body 1, a first shaft column 2 is rotatably connected inside the body 1, a first driven pulley 3 is fixedly installed on the outer side of the first shaft column 2, a first belt 4 is sleeved on the outer side of the first driven pulley 3, a second shaft column 5 is rotatably connected inside the body 1, a first driving pulley 6 is fixedly installed on the outer side of the second shaft column 5, the first belt 4 is sleeved on the outer side of the first driving pulley 6, a motor 7 is fixedly installed inside the body 1, the second shaft column 5 is fixedly installed on the output end of the motor 7, a correction wheel 8 is fixedly installed on the outer side of the first shaft column 2, and the correction wheel 8 is rotatably connected to the inside of the body 1, as shown in FIG. Figure 3 As shown, the body 1 is internally rotatably connected with a second driven pulley 9, the second shaft column 5 is fixedly mounted with a second driving pulley 10, the second driving pulley 10 is sleeved with a second belt 20, and the second belt 20 is sleeved with the outside of the second driven pulley 9.

[0022] It should be noted that, when the lawn mowing robot is working, the first driving pulley 6 is rotated by starting the motor 7, so that the first driven pulley 3 is rotated synchronously through the transmission of the first belt 4, thereby driving the first shaft column 2 to rotate. The upper and lower parts of the surface of the first shaft column 2 are respectively installed with correction wheels 8. When the robot collides with an object during operation, since the correction wheel 8 protrudes from the body 1, the object will contact the correction wheel 8 first, thereby avoiding damage to the body 1. Since the correction wheel 8 rotates counterclockwise at this time, it should be noted that Figure 4 For the observation angle, the correction wheel 8 on the left rotates counterclockwise, and the correction wheel 8 on the right rotates clockwise. Therefore, when the correction wheel 8 on the left collides with an object, the rotation of the correction wheel 8 will drive the machine body 1 to move to one side of the object, or push the object to one side of the machine body 1. The same is true for the right side, so that the object deviates from the forward direction of the machine body 1, and then the forward direction of the machine body 1 is corrected, so as to avoid the phenomenon that the object blocks the forward movement of the machine body 1 and causes the machine body 1 to fail to operate normally.

[0023] Further, such as Figure 3 As shown, a transmission disc 11 is fixedly installed on the top of the second driven pulley 9, and a first connecting rod 12 is rotatably connected to the top of the transmission disc 11. A fixing rod 13 is fixedly installed on the top of the first connecting rod 12, and a correction plate 15 is fixedly installed on one end of the fixing rod 13. Through the setting of the correction plate 15, the movement direction of the correction plate 15 on one side is consistent with that of the correction wheel 8 on the corresponding side, and the correction plate 15 is slidably connected to the inside of the body 1, and a second connecting rod 14 is fixedly installed on the top of the fixing rod 13. A slider 16 is fixedly installed on the top of the second connecting rod 14, and a sliding limit frame 17 is sleeved on the outer side of the slider 16. A slide plate 18 is fixedly installed on one side of the sliding limit frame 17, and a fixed limit frame 19 is fixedly installed inside the body 1, and the slide plate 18 is slidably connected to the inner side of the fixed limit frame 19.

[0024] It should be noted that, when the second shaft column 5 rotates, the second driving pulley 10 is driven to rotate at the same time, and the second driven pulley 9 is rotated through the transmission of the second belt 20, and the transmission plate 11 on the top of the second driven pulley 9 rotates at the same time, thereby driving the first connecting rod 12 to make the fixed rod 13 perform a circular motion, and at the same time the slider 16 slides on the inner side of the sliding limit frame 17, and the sliding limit frame 17 drives the slide plate 18 to slide on the inner side of the fixed limit frame 19, so as to limit the moving trajectory of the correction plate 15, thereby prompting the correction plate 15 to move. The correction plate 15 performs circular sliding. When the correction plate 15 performs a left circular sliding, the correction plate 15 protrudes from the machine body 1 and is pushed to one side during movement. Therefore, when the machine body 1 collides head-on with an obstacle, the correction ability of the correction wheel 8 is reduced. The movement of the correction plate 15 can assist the correction wheel 8 in correcting the position of the machine body 1. When the correction plate 15 performs a right circular sliding, the correction plate 15 moves inside the machine body 1 to avoid pushing in the opposite direction. In this way, the machine body 1 can be corrected when a head-on collision occurs, and the correction wheel 8 can be assisted in correcting the machine body 1.
