As an important safety device, the buffer mechanism provides important protection and support for robots. It not only brings higher safety and production efficiency to the application of robots, but also provides important support and guarantee for the further development of robot technology.

[0003] The buffer mechanism for robots mainly utilizes the properties of materials such as springs, gases, liquids or soft materials to absorb, disperse and transfer energy to reduce the impact force during collision, thereby protecting the robot and the surrounding environment from damage. These mechanisms can provide important protection and support during the movement of the robot, ensuring the safety and stability of the robot.

[0004] In the field of household appliances, sweeping robots generally do not have a buffer mechanism on the outside. During their operation, they will have certain collisions and contacts with furniture, which will cause wear of the internal components of the robot over a long period of time, thereby reducing the service life of the sweeping robot and increasing the cost of use. Therefore, a buffer mechanism for the robot is proposed to solve the above problem. Utility Model Content

[0022] 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.

[0023] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a buffer mechanism for a robot, including a protective main board 1, a sub-board 2 is slidably connected to one side of the outer wall of the protective main board 1, a rotating shaft 3 is fixedly connected to one side of the outer wall of the sub-board 2, the outer wall of the rotating shaft 3 is rotatably connected to a connecting block 4, a damper 5 is fixedly connected to one side of the outer wall of the connecting block 4, one end of the damper 5 is fixedly connected to a connecting block 2 7, one side of the outer wall of the connecting block 4 is fixedly connected to a spring 6, one end of the spring 6 is fixedly connected to one side of the outer wall of the connecting block 2 7, one side of the outer wall of the connecting block 2 7 is rotatably connected to a rotating shaft 2 8, the outer wall of the rotating shaft 2 8 is fixedly connected to a fixed block 9, and a fixed component is arranged on one side of the outer wall of the fixed block 9;

[0024] Specifically, when the robot is using the buffer mechanism, when it is hit, the impact object will first contact the protective main board 1, and then the impact force will be transmitted from the protective main board 1 to the sub-board 2, and then the impact force will be transmitted to the connecting block 4 through the rotating shaft 3. At this time, the damper 5 will absorb and disperse the collision energy to slow down the movement speed of the robot. In addition, the collision force compresses the spring 6, so that the spring 6 absorbs and stores energy. Then, the spring 6 releases the stored energy and converts it into mechanical energy, thereby slowing down the impact force of the robot's movement. Therefore, the mechanism can absorb and disperse energy when the robot collides with an obstacle, reducing the impact force of the collision, which helps to protect the robot's components from damage and extend the robot's service life. At the same time, it also reduces damage to the surrounding environment and items such as furniture. In addition, the structure can also reduce the noise and vibration generated during the collision, thereby improving the working comfort of the sweeping robot, which is especially important for the home environment and can reduce user interference and discomfort.

[0025] Reference Figure 1 - Figure 3 The fixing assembly includes a fixing bolt 10 and a connecting plate 11, the outer wall of the fixing bolt 10 is threadedly connected to the inside of the connecting plate 11, and one side of the outer wall of the connecting plate 11 is fixedly connected to one side of the outer wall of the fixing block 9;

[0026] Specifically, when the robot buffer mechanism needs to be used, the robot buffer mechanism is first installed on the main body of the device through the fixing bolts 10 and the connecting plate 11, and the connection is ensured to be firm.

[0027] Reference Figure 1 - Figure 3 , a hole groove 19 is provided inside the protective main board 1 and the sub-board 2, a sliding door 13 is slidably connected inside the protective main board 1, an anti-slide plate 14 is fixedly connected to one side of the outer wall of the sliding door 13, a shift block 16 is slidably connected inside the sliding door 13, a sliding groove 15 is provided inside the sliding door 13, the outer wall of the shift block 16 is slidably connected inside the sliding groove 15, a rotating column 17 is fixedly connected to one side of the outer wall of the shift block 16, the outer wall of the fixing bolt 10 is threadedly connected to the robot body 12, the outer wall of the rotating column 17 is fixedly connected to the limiting column 18, and the outer wall of the limiting column 18 is slidably connected inside the hole groove 19;

[0028] Specifically, when the protective mainboard 1 of the buffer mechanism of the robot needs to be replaced, the sliding door 13 is first lifted upwards. After the sliding door 13 is opened, the shifting block 16 is moved, and the rotating column 17 is driven to rotate by the shifting block 16, and then the limiting column 18 is driven to rotate. When the limiting column 18 rotates from a horizontal state to a vertical state, the rotating column 17 is pulled out, and the protective mainboard 1 can be removed at this time, and then the intact protective mainboard 1 is inserted from the top of the sub-plate 2 along the protruding part. When the protective mainboard 1 is installed, the rotating column 17 is inserted, and then the limiting column 18 is rotated to a horizontal state. Yes, a slide groove 15 is provided inside the sliding door 13, and its width matches that of the shift block 16, so when the sliding door 13 is lowered, the shift block 16 can be limited to prevent it from rotating. This mechanism improves the maintainability of the sweeping robot. With the long-term use of the sweeping robot, the anti-collision mainboard may need to be replaced due to collision, aging or failure. If the anti-collision mainboard is designed to be easy to replace, maintenance personnel can easily remove the damaged mainboard and install a new one without the need for tedious disassembly and assembly processes, which greatly saves maintenance time and reduces the difficulty and cost of maintenance.

[0029] Working principle: When using the buffer mechanism for the robot, when it is hit, the impact object will first contact the protective main board 1, and then the impact force will be transmitted to the sub-board 2 through the protective main board 1. After the sub-board 2 is hit, it will drive the connecting block 4 to move, and then squeeze the damper 5 and the spring 6. When the damper 5 and the spring 6 are compressed, the damper 5 and the spring 6 will absorb and disperse their impact force respectively to reduce the impact force caused by the collision. When the protective main board 1 needs to be replaced, first push the sliding door 13 upward, and then drive the rotating column 17 to rotate through the shifting block 16, and then the rotating column 17 drives the limiting column 18 to rotate. When the limiting column 18 rotates to a vertical state, the rotating column 17 can be pulled out, and the protective main board 1 can be removed at this time, and then the intact protective main board 1 is pressed down from the bottom along the protruding part of the sub-board 2 until it is completely consistent with the sub-board 2. At this time, the limiting assembly is reinserted and the rotating column 17 is rotated. At this time, the replacement of the protective main board 1 can be completed.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
