[0030] Please refer to Figures 1-5 , a shock absorption mechanism for the power wheel of an industrial robot, including a support 1. A clamping component is arranged on the support 1 through a fixing component. The clamping component includes an ejector rod 2, a first spring 3, a fixed sleeve 4, a rotating plate 5, a rotating block 6, a moving groove 7 and a limiting groove 8. The ejector rod 2 is fixedly installed on the support 1, the first spring 3 is fixedly installed on the ejector rod 2, the fixed sleeve 4 is fixedly installed on the top of the first spring 3, the rotating plate 5 is rotatably connected to the fixed sleeve 4, the rotating block 6 is connected to the rotating plate 5, the moving groove 7 is opened on the rotating block 6, the moving groove 7 is adapted to one end of the fixed sleeve 4, the limiting groove 8 is opened on the fixed sleeve 4, and the limiting groove 8 is adapted to the rotating block 6. The fixing component includes a fixed rod 9, a second spring 10 and an insertion rod 11. The fixed rod 9 is slidably connected to the inside of the fixed sleeve 4, the second spring 10 is installed inside the fixed sleeve 4, the second spring 10 abuts against the fixed rod 9, the insertion rod 11 is slidably connected to the fixed sleeve 4, and a shock absorption component is arranged on the support 1.

[0031] A mounting plate 12 is fixedly installed on the fixed sleeve 4, and a tension spring 13 is connected between the mounting plate 12 and the rotating plate 5.

[0032] A third spring 14 is installed on the fixed sleeve 4, and an unlocking block 15 is connected to the third spring 14.

[0033] The unlocking block 15 is provided with a pushing groove 16.

[0034] A rolling ball 17 is connected to the insertion rod 11. The rolling ball 17 is adapted to the unlocking block 15, and a fifth spring 18 is sleeved on the insertion rod 11.

[0035] The fixed sleeve 4 is provided with a buffer groove 19. The fifth spring 18 is arranged in the buffer groove 19. The fixed rod 9 is provided with a fixing groove 20, and the fixing groove 20 is adapted to the insertion rod 11.

[0036] In this embodiment, during the use process, when this mechanism needs to be quickly replaced, since the fixed rod 9 is connected to the bottom chassis of the robot, during the replacement, by manually rotating the rotating plate 5, during the rotation process, the rotating block 6 is driven to rotate. And when the moving groove 7 of the rotating block 6 moves to the limiting groove 8, the unlocking block 15 is manually slid along the outside of the fixed sleeve 4. During the moving process, the rolling ball 17 is pushed to move outward, and the third spring 14 is stretched. And during the rotation of the rotating plate 5, the tension spring 13 between the fixing plate and the rotating plate 5 is stretched. When the rolling ball 17 moves, the insertion rod 11 moves, so as to move it out of the fixing groove 20 on the fixed rod 9. And when the insertion rod 11 moves, the fifth spring 18 in the buffer groove 19 is compressed. At this time, the fixing of the fixed rod 9 is released, and the fixed rod 9 and the chassis of the robot can be removed, and the replacement process of this mechanism can be completed. When fixing a new mechanism, the above operations are repeated.

[0037] Please refer to Figure 5 , as an implementation manner of the shock-absorbing mechanism of the driving wheel of an industrial robot for the shock-absorbing component: The shock-absorbing component includes a fourth spring 21, a rotating shaft 22 and a hub 23. The fourth spring 21 is fixedly installed on the bracket 1. The rotating shaft 22 is rotatably connected to both ends of the bracket 1, and the hub 23 is connected to the rotating shaft 22.

[0038] A tire 24 is arranged on the outside of the hub 23.

[0039] More specifically, during the use process of this mechanism, since the walking road is inevitably uneven, during the moving process of this mechanism, the tire 24 rotates and moves along the hub 23 and the rotating shaft 22 at both ends of the bracket 1. When the road surface is uneven, the tire 24 will move upward. Since the robot chassis installed at the top of the fixed rod 9 is fixed, the first spring 3 connected between them will be squeezed, so as to utilize the elastic potential energy of the first spring 3 to play a role in shock absorption during the moving process of this industrial robot.

[0040] In summary, when the overall device is in use or operation: during use, when this mechanism needs to be quickly replaced, since the fixing rod 9 is connected to the bottom chassis of the robot, during replacement, when an operator rotates the rotating plate 5, during the rotation process, the rotating block 6 is driven to rotate. And when the moving groove 7 of the rotating block 6 moves to the limiting groove 8, the operator slides the unlocking block 15 along the outer side of the fixed sleeve 4. During the movement, the rolling ball 17 is pushed to move outward, and the third spring 14 is stretched. And during the rotation of the rotating plate 5, the tension spring 13 between the fixed plate and the rotating plate 5 is stretched. When the rolling ball 17 moves, the insertion rod 11 moves, so as to be removed from the fixing groove 20 on the fixing rod 9. And when the insertion rod 11 moves, the fifth spring 18 in the buffer groove 19 is compressed. At this time, the fixing of the fixing rod 9 is released, and the fixing rod 9 and the chassis of the robot can be removed, and the replacement of this mechanism can be completed. When fixing a new mechanism, the above operations are repeated.

[0041] During the use of this mechanism, since the walking path will inevitably have uneven places, during the movement of this mechanism, the tire 24 rotates and moves along the hub 23 and the rotating shaft 22 at both ends of the bracket 1. When the road surface is uneven, the tire 24 will move upward. Since the robot chassis installed at the top of the fixing rod 9 is fixed, the first spring 3 connected between them will be compressed, so as to utilize the elastic potential energy of the first spring 3 to play a shock absorption role for this industrial robot during movement.

[0042] In all the above-mentioned solutions, for the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
