Description

Technical Field

[0001] This utility model relates to the field of robot technology, and in particular to a shock absorption device for robot transmission components. Background Technology

[0002] With the continuous development of robotics technology, the application fields of robots are becoming increasingly widespread, covering many aspects such as industrial production, logistics and transportation, medical services, and home assistance. However, the vibration problem generated by the robot's transmission components during operation remains a key factor restricting its performance improvement and stable operation.

[0003] Existing vibration reduction measures are often too simplistic and fail to comprehensively and effectively address the vibration issues of robot transmission components. For example, there is no good solution for the transmission belts in robot transmission parts, where loosening caused by vibration leads to transmission instability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shock absorption device for robot transmission components.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shock-absorbing device for a robot transmission component includes a mounting plate, on the side wall of which a transmission mechanism is fixedly mounted, the transmission mechanism including a first bearing;

[0007] The first bearing is fixedly installed on the side wall of the mounting plate, and a first wheel is rotatably installed inside the first bearing. A transmission belt is drivenly installed on the side wall of the first wheel, and a connecting plate is fixedly installed on the side wall of the mounting plate.

[0008] The connecting plate is equipped with a shock-absorbing component, a sliding block is installed on the shock-absorbing component, and a second rotating wheel is rotatably installed inside the sliding block. The side wall of the second rotating wheel is connected to the side wall of the transmission belt.

[0009] Preferably, the shock absorption assembly includes a first damping rod fixedly installed at the bottom of the connecting plate, and the other end of the first damping rod is connected to the bottom of the sliding block.

[0010] Preferably, a first spring is sleeved on the outer side of the first damping rod, and the other end of the first spring is connected to the bottom of the sliding block.

[0011] Preferably, there are two first bearings, located on both sides of the mounting plate, and the transmission belt drives and connects the two first pulleys and the second pulley.

[0012] Preferably, a connector is fixedly installed on the side wall of the first rotating wheel, and a rubber ring is sleeved on the outside of the connector.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This shock absorption device, through the coordinated operation of a first spring, a first damping rod, a sliding block, and a second rotating wheel, can automatically adjust when the transmission belt becomes loose. The first spring extends according to the change in force on the transmission belt, and the first damping rod precisely limits its extension speed to prevent rebound. Then, together they drive the sliding block to raise the second rotating wheel, tightening the transmission belt. This mechanism effectively maintains the stable operation of the transmission system, reduces problems such as transmission instability and slippage caused by a loose transmission belt, ensures the reliability of power transmission in the robot's transmission components, and extends the service life of the transmission belt and related components.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a shock-absorbing device for a robot transmission component, applied to the chassis mechanism of a robot using belt drive. It includes a mounting plate 11, a first bearing 12 fixedly mounted on the side wall of the mounting plate 11, a first wheel 13 rotatably mounted inside the first bearing 12, a transmission belt 14 drivenly mounted on the side wall of the first wheel 13, a connecting plate 15 fixedly mounted on the side wall of the mounting plate 11, a first damping rod 16 fixedly mounted inside the connecting plate 15, a first spring 17 disposed on the side wall of the first damping rod 16, the bottom of the first spring 17 fixedly mounted to the connecting plate 15, a sliding block 18 slidably mounted inside the connecting plate 15, the bottom of the sliding block 18 fixedly mounted to the first damping rod 16 and the first spring 17, a second wheel 19 rotatably mounted inside the sliding block 18, the side wall of the second wheel 19 drivenly mounted to the side wall of the transmission belt 14, and two first bearings 12 respectively located on both sides of the mounting plate 11, the transmission belt drivingly connecting the two bearings 12. When the robot is started, the first wheel 13 drives the transmission belt 14 to rotate counterclockwise, and the transmission belt 14 drives the second wheel 19 to rotate counterclockwise. The second wheel 19 is connected to the drive end of the drive motor to realize the rotation of the second wheel 19. The drive motor is mounted on the robot body or directly on the walking chassis of the robot body. The connection method can be bolt connection. The first wheel 13 rotates inside the first bearing 12 and is connected to the robot's walking wheel. The connection method can be bolt connection. When the transmission belt 14 becomes loose due to vibration, the first spring 17 will extend and the first damping rod 16 will limit the first spring 17 to prevent the first spring 17 from extending too fast and causing rebound. The first spring 17 and the first damping rod 16 drive the sliding block 18 to rise slowly. The sliding block 18 slides inside the connecting plate 15. The sliding block 18 will cause the second wheel 19 to rise and tighten the transmission belt 14.

[0024] A mounting block 21 is fixedly installed on the side wall of the first bearing 12. The first bearing 12 will be connected to the mounting block 21 and the mounting plate 11 to increase stability.

[0025] A connector 26 is fixedly installed on the side wall of the first rotating wheel 13. A rubber ring 25 is sleeved on the outside of the connector 26. The robot's walking wheel can be installed on the outside of the first rotating wheel 13 by means of the rubber ring 25, which further reduces vibration.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
