[0002] The emergence of floor grinding robots is a product of the deep integration of artificial intelligence and robotics technology. With the continuous advancement of artificial intelligence technology, especially the maturity of deep learning, machine vision, and autonomous navigation technologies, robots have acquired higher levels of intelligence and autonomous operation capabilities.

[0003] However, in the existing technology, during the rotation and storage process, the end of the pry bar is prone to collision and damage with the grinding disc or other components under the gravity of the counterweight. Utility Model Content

[0004] The purpose of this invention is to propose a floor grinding robot with a limit lever, which solves the problem in the prior art where the end of the lever is easily damaged by collision with the grinding disc or other components under the gravity of the counterweight during the rotation and storage process.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] The rotating part is rotatably mounted on the robot body, the first limiting member is mounted on the robot body, the second limiting member is mounted on the rotating part, and the second limiting member can abut against the first limiting member;

[0008] The limiting platform is installed on the robot body, the pry bar is installed on the rotating part, the pry bar is provided with a counterweight, and the counterweight can abut against the limiting platform.

[0009] Furthermore, it also includes a mounting base, one end of which is mounted on the robot body, and the other end of which is mounted on the limiting platform.

[0012] The first mounting section is mounted on the robot body, one end of the connecting section is connected to the first mounting section, the other end of the connecting section is connected to the second mounting section, and the connecting section is inclined. The second mounting section is equipped with the limiting platform.

[0013] In some embodiments, the rotating part includes a rotating rod, a first anti-rotation block, and a mounting sleeve;

[0014] The robot body is provided with a first anti-rotation plate, the first anti-rotation plate is provided with a first anti-rotation groove, the rotating rod is rotatably mounted on the first anti-rotation plate, and the rotating rod is movably mounted on the first anti-rotation plate.

[0016] When the first anti-rotation block is engaged in the first anti-rotation groove, the pry bar and the first anti-rotation plate are in a relatively stationary state.

[0017] When the first anti-rotation block disengages from the first anti-rotation groove, the pry bar and the first anti-rotation plate are in a state of relative rotation.

[0018] Furthermore, the rotating part also includes a second anti-rotation block;

This limits the placement of the lever and prevents it from continuing to swing downwards under the weight of the counterweight, thus avoiding collision and damage to the grinding disc or other components. This helps to extend the service life of the floor grinding robot. Attached Figure Description

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0036] In one embodiment of this utility model, such as Figure 1-5As shown, a floor grinding robot with a limit lever includes a robot body 1, a lever 2, a limiting platform 3, a first limiting member 5, a second limiting member 6, and a rotating part 7. The rotating part 7 is rotatably mounted on the robot body 1, the first limiting member 5 is mounted on the robot body 1, the second limiting member 6 is mounted on the rotating part 7, and the second limiting member 6 can abut against the first limiting member 5. The limiting platform 3 is mounted on the robot body 1, the lever 2 is mounted on the rotating part 7, and the lever 2 is provided with a counterweight 21, which can abut against the limiting platform 3. In this embodiment, there are two of each of the following: the pry bar 2, the limiting platform 3, the first limiting member 5, the second limiting member 6, and the rotating part 7. The two rotating parts 7 are respectively installed on the left and right sides of the robot body 1. The two first limiting members 5 are respectively installed on the left and right sides of the robot body 1, with the first limiting members 5 located behind the rotating parts 7. The two limiting platforms 3 are respectively installed on the left and right sides of the robot body 1, with the limiting platforms 3 located in front of the rotating parts 7. One end of the pry bar 2... Mounted on the rotating part 7, the other end of the pry bar 2 is provided with a counterweight 21. The counterweight 21 has a trapezoidal cross-section. When the pry bar 2 is in the retracted state, the two pry bars 2 rotate through the corresponding rotating part 7, causing the two counterweights 2 to swing closer to the corresponding limiting platform 3 until the two counterweights 21 abut against the corresponding limiting platform 3. Specifically, the trapezoidal side of the counterweight 21 abuts against the top surface of the limiting platform 3, thereby ensuring uniform force during limiting. At this time, the two pry bars 2 are respectively located on the robot body 1. The outer sides of the left and right sides are used to limit and store the two pry bars 2, preventing them from swinging downwards and colliding with the grinding disc or other components below. When the grinding disc of the robot body 1 needs to be replaced or repaired, the two pry bars 2 rotate through the corresponding rotating parts 7, causing the two counterweights 21 to swing away from the corresponding limiting platform 3 until the two second limiting members 6 respectively abut against the corresponding first limiting members 5. At this time, the counterweights 21 of the two pry bars 2 are located on the left and right sides of the robot body 1. The upper rear section allows workers to easily grip the two levers 2 and swing the robot body 1 along the wheels. This application, through the robot body 1, levers 2, limiting platform 3, first limiting member 5, second limiting member 6, and rotating part 7, ensures that when the levers 2 are in the retracted state, the limiting platform 3 can limit the placement of the counterweight 21, thereby limiting the placement of the levers 2 and preventing them from continuing to swing downwards under the gravity of the counterweight 21 and colliding with the grinding disc or other components, thus improving the service life of the floor grinding robot.

[0037] like Figure 1-2As shown, it also includes a mounting base 8, one end of which is mounted on the robot body 1, and the other end of which is mounted on the limiting platform 3. In this embodiment, one end of the mounting base 8 is mounted on the robot body 1, and the other end of the mounting base 8 is mounted on the limiting platform 3. The mounting base 8 facilitates the placement of the limiting platform 3 on the outside of the robot body 1, so that the counterweight 21 can be directly opposite the limiting platform 3.

[0038] like Figure 4-5 As shown, it also includes a locking nut 9. The bottom of the limiting platform 3 is provided with a locking screw 31. The locking screw 31 is detachably installed on the mounting base 8, and the locking nut 9 is installed on the screw 31. In this embodiment, during installation, the locking screw 31 at the bottom of the limiting platform 3 is installed from top to bottom into the through hole of the mounting base 8, so that the bottom surface of the limiting platform 3 is in contact with the top surface of the mounting base 8. Then, the locking nut 9 is installed on the locking screw 31 until the top surface of the locking nut 9 is in contact with the bottom surface of the mounting base 8, thereby achieving the purpose of locking and fixing. This is convenient and quick. The detachable installation of the limiting platform 3 makes it easy to replace the limiting platform 3 that frequently collides with the counterweight 21.

[0039] like Figure 2-3 As shown, the mounting base 8 includes a first mounting section 81, a second mounting section 82, and a connecting section 83. The first mounting section 81 is mounted on the robot body 1. One end of the connecting section 83 is connected to the first mounting section 81, and the other end of the connecting section 83 is connected to the second mounting section 82. The connecting section 83 is inclined. The second mounting section 82 is equipped with the limiting platform 3. In this embodiment, one end of the connecting section 83 is connected to the first mounting section 81, and the other end of the connecting section 83 is connected to the second mounting section 82. The connecting section 83 is inclined, and a three-section inclined transition structure is used instead of a flat plate structure. This makes the mounting base 8 less prone to deformation and breakage when subjected to force by the limiting platform 3, which helps to improve the service life of the mounting base 8.

[0040] like Figure 4-5As shown, the rotating part 7 includes a rotating rod 71, a first anti-rotation block 72, and a mounting sleeve 73; the robot body 1 is provided with a first anti-rotation plate 11, the first anti-rotation plate 11 is provided with a first anti-rotation groove 111, the rotating rod 71 is rotatably mounted on the first anti-rotation plate 11, and the rotating rod 71 can be moved left and right while mounted on the first anti-rotation plate 11; the mounting sleeve 73 is mounted on one end of the rotating rod 71, the mounting sleeve 73 is equipped with the pry bar 2, the first anti-rotation block 72 is mounted on the other end of the rotating rod 71, and the first anti-rotation block 72 can be snapped into the first anti-rotation groove 111; when the first anti-rotation block 72 is snapped into the first anti-rotation groove 111, the pry bar 2 and the first anti-rotation plate 11 are in a relatively stationary state; when the first anti-rotation block 72 is disengaged from the first anti-rotation groove 111, the pry bar 2 and the first anti-rotation plate 11 are in a relatively rotating state. In this embodiment, there are two first anti-rotation plates 11, which are located on the left and right sides of the robot body 1. Both the first anti-rotation block 72 and the first anti-rotation groove 111 are of a straight-line structure. When rotation is required, the mounting sleeve 73 is pushed towards the center of the robot body 1, causing the mounting sleeve 73 to push the rotating rod 71 inward, thus disengaging the first anti-rotation block 72 from the first anti-rotation groove 111. At this time, the rotating rod 71 can rotate along the mounting point of the first anti-rotation plate 11, specifically rotating 180°. After rotation to the desired position, the mounting sleeve 73 is pulled outward, causing the first anti-rotation block 72 to engage with the first anti-rotation groove 111. When the rotating rod 71 cannot rotate, the pry bar 2 is fixed, which is convenient and quick. Furthermore, when the pry bar 2 is stored and fixed, it is not only fixed by the first anti-rotation block 72 and the first anti-rotation groove 111, but also fixed by the limiting platform 3. This helps to improve the fixing quality of the pry bar 2, reduce the stress load on the limiting platform 3, and improve the service life of the limiting platform 3. When the pry bar 2 is unfolded and fixed, it is not only fixed by the first anti-rotation block 72 and the first anti-rotation groove 111, but also fixed by the first limiting member 5 and the second limiting member 6. This helps to improve the fixing quality of the pry bar 2, reduce the stress load on the first limiting member 5 and the second limiting member 6, and improve the service life of the first limiting member 5 and the second limiting member 6.

[0041] like Figure 4-5As shown, the rotating part 7 further includes a second anti-rotation block 74; the robot body 1 is provided with a second anti-rotation plate 12, the second anti-rotation plate 12 is located outside the first anti-rotation plate 11, the second anti-rotation plate 12 is provided with a second anti-rotation groove 121, and the first limiting member 5 is installed on the second anti-rotation plate 12; the rotating rod 71 is rotatably installed on the second anti-rotation plate 12, the rotating rod 71 is movable left and right on the second anti-rotation plate 12, the second anti-rotation block 74 is installed on the rotating rod 71, the second anti-rotation block 74 is located outside the first anti-rotation block 72, and the second anti-rotation block 74 can be engaged in the second anti-rotation groove 121; when the second anti-rotation block 74 is engaged in the second anti-rotation groove 121, the pry bar 2 and the second anti-rotation plate 12 are in a relatively stationary state; when the second anti-rotation block 74 is disengaged from the second anti-rotation groove 121, the pry bar 2 and the second anti-rotation plate 12 are in a relatively rotating state. In this embodiment, the first limiting member 5 is specifically installed on the outer side of the second anti-rotation plate 12. The first anti-rotation plate 11 and the second anti-rotation plate 12 have the same structure and are arranged opposite each other in the left-right direction. The first anti-rotation block 72 and the second anti-rotation block 74 have the same structure and are arranged opposite each other in the left-right direction. That is, the anti-rotation principle of the second anti-rotation block 74 and the second anti-rotation plate 12 is the same as that of the first anti-rotation block 72 and the first anti-rotation plate 11. By setting two sets of anti-rotation structures, the anti-rotation fixing effect of the pry bar 2 is further improved, the load on the stressed parts is reduced, and its service life is improved.

[0042] like Figure 4-5 As shown, the rotating part 7 also includes an elastic element 75; one end of the elastic element 75 is installed on the robot body 1, and the other end of the elastic element 75 abuts against the rotating rod 71. The elastic element 75 is located inside the first anti-rotation plate 11. In this embodiment, there are two elastic elements 75, each being a spring. One end of each elastic element 75 is installed on the robot body 1, and the other end of each elastic element 75 abuts against the rotating rod 71. Both elastic elements 75 are located inside the first anti-rotation plate 11. When the rotating rod 71 moves towards the center of the robot body 1 and presses, the elastic element 75 is compressed. After the pry bar 2 has rotated, under the elastic force of the elastic element 75, the rotating rod 71 moves outward to reset, causing the first anti-rotation block 72 and the second anti-rotation block 74 to respectively engage in the first anti-rotation groove 111 and the second anti-rotation groove 121, thereby achieving automatic reset, which is convenient and quick.

[0043] like Figure 4-5As shown, it also includes a locking screw 4, and the pry bar 2 is detachably mounted to the mounting sleeve 73 via the locking screw 4. In this embodiment, one end of the mounting sleeve 73 is mounted to the rotating rod 71, and the other end of the mounting sleeve 73 is provided with a mounting hole. The end of the pry bar 2 is mounted in the mounting hole of the mounting sleeve 73, and the pry bar 2 is perpendicularly connected to the mounting sleeve 73. Then, the end of the locking screw 4 is installed through the end of the pry bar 2, thereby locking the pry bar 2 to the mounting sleeve 73. The detachability of the pry bar 2 facilitates its maintenance and replacement.
