Description
Technical Field
[0001] This utility model relates to the field of floor grinding equipment technology, and in particular to a cycloidal assembly and its floor grinding robot. Background Technology
[0002] Floor grinding robots are automated equipment used for floor surface treatment, and are widely used in floor grinding work in underground garages, factory workshops, laboratories, sports venues and other scenarios.
[0003] In the design of floor grinding robots, the layout and management of power cables is a critical factor. Traditional power cable wiring methods may cause the power cables to easily get tangled at the bottom of the robot, affecting its normal operation.
[0004] Currently, there is a lack of effective power cord management solutions that can secure the power cord while allowing it sufficient rotational freedom during the movement of the floor grinding robot, and simultaneously prevent the power cord from getting tangled. Therefore, a new power cord management solution is urgently needed to address the problem of power cords easily getting caught in the bottom of the robot. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this utility model is to propose a cycloidal assembly and its floor grinding robot, which solves the problem that current power cord fixing methods cannot flexibly cooperate with the floor grinding robot's operation, and that unfixed power cords are easily caught in the bottom of the floor grinding robot.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A cycloidal assembly for a floor grinding robot includes a connecting part, a first swing arm, a second swing arm, a first hook, and a second hook. The connecting part is connected to one end of the first swing arm, the middle part of the first swing arm is pivotally connected to one end of the second swing arm, the other end of the second swing arm is connected to the second hook, the first hook is disposed on the first swing arm, and the first hook is located between the second swing arm and the connecting part. The connecting part is used to pivotally connect to the floor grinding robot.
[0008] Preferably, it further includes a limiting rod, which is connected to the second swing arm and can swing with the second swing arm. The limiting rod is used to limit the swing of the second swing arm to more than 180°.
[0009] Preferably, the second hook is positioned above the second swing arm, the second hook has an open-loop structure, and the opening of the second hook is located at the highest point.
[0010] Preferably, the length of the second swing arm is greater than the length of the first swing arm.
[0011] Preferably, it further includes three winding rods, which are spaced apart along the length of the second swing arm, with the middle winding rod located at the top of the second swing arm and the other two winding rods located on the side of the second swing arm.
[0012] Preferably, it further includes a rotating part, through which the first swing arm is connected to the second swing arm. The rotating part is provided with a first rotating shaft and a second rotating shaft. The first rotating shaft is connected to the first swing arm, and the second rotating shaft is connected to the second swing arm. The first rotating shaft and the second rotating shaft are arranged perpendicular to each other.
[0013] Preferably, the rotating part is provided with a first positioning block and a second positioning block. The first positioning block and the second positioning block are used to limit the rotation angle of the second swing arm and avoid the second swing arm from colliding with the first swing arm or the shell of the floor grinding robot.
[0014] Preferably, the connecting part adopts a hinge structure, and a positioning through hole is provided at the end of the first swing arm away from the connecting part, the positioning through hole being used for positioning the first swing arm.
[0015] Preferably, it also includes a collision avoidance block, which is disposed at the end of the second swing arm away from the first swing arm.
[0016] A floor grinding robot includes a moving component, a grinding component, a driving component, and the aforementioned cycloidal component. The moving component is used to drive the floor grinding robot to move as a whole. The grinding component and the cycloidal component are disposed on the moving component. The grinding component is used for grinding operations. The driving component drives and connects the moving component and the grinding component. The driving component is provided with a power line, which passes through the cycloidal component.
[0017] The technical solution provided by this utility model can include the following beneficial effects:
[0018] 1. By using a cycloidal assembly, the power cord can be properly secured at the end near the floor grinding robot. Simultaneously, the power cord gains horizontal rotational freedom by following the swing of the second swing arm, solving the problem of the power cord easily getting tangled in the bottom of the floor grinding robot during movement. This also addresses the issue of restricted robot movement if the power cord is fixed.
[0019] 2. The limiting rod is used to limit the swing angle of the second swing arm, so that the second swing arm cannot be completely parallel to the first swing arm, thus solving the problem of the power cord being pinched and damaged when the second swing arm swings to coincide with the first swing arm.
[0020] 3. The second hook is set at the top, and the power cord is confined inside the second hook by the open loop structure, which makes it easy to put the power cord in and out, and to adjust the winding method and length of the power cord in time. At the same time, the open loop structure further increases the freedom of swing of the power cord and avoids the problem of the power cord being easily damaged when it is completely confined.
[0021] 4. By setting a longer second swing arm, when the second swing arm swings to both sides, the second hook can extend beyond the width of the floor grinding robot from the side, further avoiding the problem of the power cord being tangled.
[0022] 5. The use of a winding rod facilitates the suspension and winding of the power cord. At the same time, the non-coplanar arrangement of the three winding rods increases the friction when the power cord is wound, preventing the power cord from accidentally coming loose and slipping.

[0034] The embodiments of this utility model are described below with reference to the accompanying drawings.
[0035] A cycloidal assembly for a floor grinding robot includes a connecting part 1, a first swing arm 2, a second swing arm 3, a first hook 4, and a second hook 5. The connecting part 1 is connected to one end of the first swing arm 2, the middle part of the first swing arm 2 is pivotally connected to one end of the second swing arm 3, the other end of the second swing arm 3 is connected to the second hook 5, the first hook 4 is disposed on the first swing arm 2, and the first hook 4 is located between the second swing arm 3 and the connecting part 1. The connecting part 1 is used to pivotally connect to the floor grinding robot.
[0036] like Figure 1 As shown, in a specific embodiment, the first swing arm 2 is horizontally positioned behind the floor grinding robot along its direction of travel, and the second swing arm 3 can swing laterally in the horizontal direction, allowing the second hook 5 to have a large swing range. The power cord of the floor grinding robot first passes through the first hook 4, then wraps around the second swing arm 3, and finally exits from the second hook 5.
[0037] By using a cycloidal assembly, the power cord can be properly secured at the end near the floor grinding robot. Simultaneously, the power cord gains horizontal rotational freedom by following the swing of the second swing arm 3, solving the problem of the power cord easily getting tangled in the bottom of the floor grinding robot during movement. This also addresses the issue of restricted robot movement if the power cord is fixed.
[0038] Preferably, it also includes a limiting rod 6, which is connected to the second swing arm 3 and can swing with the second swing arm 3. The limiting rod 6 is used to limit the second swing arm from swinging more than 180°.
[0039] The limiting rod 6 is used to limit the swing angle of the second swing arm 3, so that the second swing arm 3 cannot be completely parallel to the first swing arm, thus solving the problem that the power cord is pinched and damaged when the second swing arm 3 swings to coincide with the first swing arm 2.
[0040] Preferably, the second hook 5 is disposed above the second swing arm 3, the second hook 5 adopts an open ring structure, and the opening of the second hook 5 is disposed at the highest point.
[0041] The second hook 5 is placed at the top, and the power cord is confined inside the second hook 5 by the open-loop structure, which facilitates the removal and placement of the power cord, and allows for timely adjustment of the winding method and length of the power cord. At the same time, the open-loop structure further increases the freedom of swing of the power cord, avoiding the problem of easy damage to the power cord when it is completely confined.
[0042] Preferably, the length of the second swing arm 3 is greater than the length of the first swing arm 2.
[0043] By setting a longer second swing arm 3, when the second swing arm 3 swings to both sides, the second hook 5 can extend beyond the width direction of the floor grinding robot from the side, further avoiding the problem of the power cord being tangled.
[0044] Preferably, it further includes at least three winding rods 7, which are spaced apart along the length of the second swing arm 3, with one of two adjacent winding rods 7 located at the top of the second swing arm 3 and the other located on the side of the second swing arm 3.
[0045] like Figure 1 and Figure 3 As shown, the winding rod 7 facilitates the suspension and winding of the power cord. Furthermore, the non-coplanar arrangement of the winding rod 7 increases the friction during winding, preventing the power cord from accidentally slipping off. Preferably, three or more winding rods (within a limited number) can be used, depending on the length of the second swing arm 3, to achieve the winding of the power cord.
[0046] Preferably, it further includes a rotating part 8, the first swing arm 2 is connected to the second swing arm 3 through the rotating part 8, the rotating part 8 is provided with a first rotating shaft 81 and a second rotating shaft 82, the rotating part 8 is rotatably connected to the first swing arm 2 through the first rotating shaft 81, and the rotating part 8 is rotatably connected to the second swing arm 3 through the second rotating shaft 82, the first rotating shaft 81 and the second rotating shaft 82 are arranged perpendicular to each other.
[0047] like Figure 2 and Figure 4 As shown, the first rotating shaft 81 allows the second swing arm 3 to rotate laterally following the rotating part 8, so as to flexibly swing in coordination with the power cord. The second rotating shaft 82 allows the second swing arm 3 to rotate in the vertical direction, which makes it easy to stand the second swing arm 3 upright when storing the floor grinding robot, thus reducing the space occupied.
[0048] Preferably, the rotating part 8 is provided with a first positioning block 83 and a second positioning block 84. The first positioning block 83 and the second positioning block 84 are used to limit the rotation angle of the second swing arm 3 to avoid the second swing arm 3 from colliding with the first swing arm 2 or the shell of the floor grinding robot.
[0049] The first positioning block 83 is used to limit and support the second swing arm 3, while limiting the downward rotation angle of the second swing arm 3 so that the second swing arm 3 will not fall to the ground.
[0050] Preferably, the connecting part 1 adopts a hinge structure, and the end of the first swing arm 2 away from the connecting part 1 is provided with a positioning through hole 21, which is used for positioning the first swing arm.
[0051] In a specific embodiment, the floor grinding robot is equipped with a positioning bolt that matches the positioning through hole 21. The first swing arm 2 is fixed from both ends by the connecting part 1 and the positioning bolt. Simultaneously, after opening the positioning bolt, the first swing arm 2 can be easily rotated and opened via the hinge structure of the connecting part 1, facilitating the maintenance of the floor grinding robot.
[0052] Preferably, it also includes a crash block 9, which is disposed at the end of the second swing arm 3 away from the first swing arm 2.
[0053] Since the grinding discs at the front end of the floor grinding robot often require maintenance, the front end is usually raised for maintenance. By adding a bumper block 9 to the end of the second swing arm 3, the second swing arm 3 located at the rear end is prevented from directly hitting the ground when the front end is raised, thus avoiding damage to the ground.
[0054] A floor grinding robot includes a moving component, a grinding component, a driving component, and the aforementioned cycloidal component. The moving component is used to drive the floor grinding robot to move as a whole. The grinding component and the cycloidal component are disposed on the moving component. The grinding component is used for grinding operations. The driving component drives and connects the moving component and the grinding component. The driving component is provided with a power line, which passes through the cycloidal component.
[0055] In one embodiment, the cycloidal assembly is located in the middle of the rear side of the floor grinding robot. The drive assembly drives the moving assembly and the grinding assembly to perform floor grinding work. The robot can be manually pushed to adjust its direction. The cycloidal assembly can effectively prevent the power cord from getting caught in the moving assembly.
[0056] Other configurations and operations according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
[0057] In this specification, the terms "embodiment," "example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention.
