Description

Technical Field

[0001] This utility model relates to the field of single-rod viscous dampers, specifically to an airbag-type single-rod viscous damper. Background Technology

[0002] A single-outlet viscous damper is an important mechanical component. Its working principle is mainly based on the viscosity of the fluid and the friction of the internal structure. When an external force is applied to the damper, the fluid inside flows through specific channels, generating resistance, thereby consuming energy and reducing vibration. The airbag-storage single-outlet viscous damper is an innovative design that combines the advantages of traditional single-outlet viscous dampers. It is suitable for various applications requiring vibration reduction and energy dissipation, such as high-rise buildings, long-span bridges, and large mechanical equipment. Especially in fields with high stability requirements, such as precision machine tools and aerospace, the airbag-storage single-outlet viscous damper has a wider range of application prospects.

[0003] In existing airbag accumulator single-rod viscous dampers, the airbag directly contacts the cylinder during compression, leading to accelerated wear of the airbag. Furthermore, the lack of monitoring capabilities prevents the detection of pressure changes within the airbag and the need for replenishment, thus affecting the device's response speed and stability. Long-term use also makes maintenance and repair of the airbag accumulator single-rod viscous damper more difficult, requiring regular manual inspections and repairs, increasing maintenance costs and downtime.

[0004] Therefore, it is necessary to invent a pneumatic accumulator single-rod viscous damper to solve the above problems. Utility Model Content

Through an energy-storing airbag, a telescopic buffer spring, an inner airbag support, an inner partition, a pressure sensor, a drive control module, and inlet / outlet air pipes, this airbag-type single-pole viscous damper possesses the ability to monitor air pressure and provide auxiliary buffering for the airbag, thus enhancing stability. The combined action of the telescopic buffer spring and the energy-storing airbag makes the airbag-type single-pole viscous damper more stable under impact, reducing vibration caused by impact. It also exhibits strong adaptability; the design allows for adjustment of the air pressure within the airbag according to actual needs, thereby adapting to different working environments and requirements. Simultaneously, the pressure sensor and drive control module... The design of the control module enables real-time monitoring of the damper's status, facilitating timely detection and problem-solving, and reducing maintenance costs and downtime. This addresses the issues in existing airbag accumulator single-rod viscous dampers where, during operation, the airbag directly contacts the cylinder during compression, leading to accelerated airbag wear. Furthermore, the lack of monitoring capabilities prevents the detection of air pressure changes within the airbag and the need for timely air replenishment, thus affecting the device's response speed and stability. Long-term use also makes maintenance and repair of the airbag accumulator single-rod viscous damper more difficult, requiring regular manual inspections and repairs, increasing maintenance costs and downtime.

Furthermore, during expansion and contraction, the airbag does not directly contact the inside of the damper cylinder; instead, it contacts the inner support of the airbag and then compresses the telescopic buffer spring for auxiliary cushioning. This design allows the airbag to...

At the same time, the design of the air pressure sensor and drive control module allows the damper's status to be monitored in real time, facilitating timely detection and problem solving, reducing maintenance costs and downtime.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The airbag accumulator type single-outlet rod viscous damper shown includes a damper cylinder 1, which is the main body for supporting the single-outlet rod viscous damping assembly.

[0029] A single-outlet piston rod 2 is located inside the damper cylinder 1 to bear impact and complete damping buffering. An energy storage airbag 8 is fixedly installed at the rear end of the single-outlet piston rod 2. A telescopic buffer spring 9 is installed inside the damper cylinder 1. An airbag inner support 10 is fixedly connected to the front end of the telescopic buffer spring 9.

[0030] An inner partition 11 is disposed inside the single-outlet piston rod 2 to separate the internal space of the single-outlet piston rod 2. An air pressure sensor 12 is disposed inside the energy storage airbag 8. A connecting wire 13 is fixedly connected to the outside of the air pressure sensor 12. A drive control module 14 is fixedly installed at the other end of the connecting wire 13.

[0031] An inlet / outlet air pipe 15 is located below the inner partition 11 and is used to replenish air to the airbag. An air replenishment port 16 is fixedly provided at the front end of the inlet / outlet air pipe 15. A micro air pump 17 is fixedly installed on the outside of the damper cylinder 1. The output end of the micro air pump 17 is fixedly connected to the air replenishment pipe 18. The air pressure sensor 12 inside the energy storage airbag 8 can monitor the internal air pressure of the energy storage airbag 8 in real time and transmit the air pressure data to the drive control module 14 through a wire connection. In this way, when the internal air pressure of the energy storage airbag 8 is insufficient, air can be replenished in time through the inlet / outlet air pipe 15 and the air replenishment port 16.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a front cover 3 is fixedly installed at the front end of the damper cylinder 1, a first connecting body 4 is fixedly installed at the rear end of the damper cylinder 1, and a second connecting body 5 is fixedly installed on the outside of the front cover 3. The first connecting body 4 and the second connecting body 5 are used to assist the airbag accumulator single-rod viscous damper in connecting and installing with external equipment. An inner piston 6 is fixedly installed on the outside of the single-rod piston 2, and a spacer end 7 is fixedly installed inside the damper cylinder 1. The single-rod piston 2 drives the inner piston 6 to slide inside the damper cylinder 1, thereby squeezing the fluid medium and causing the airbag accumulator single-rod viscous damper to generate resistance and complete the buffering. The inner piston 6 is movably connected to the damper cylinder 1, and the single-rod piston 2 is slidably connected to the spacer end 7. The overall structure of the inner piston 6 is simple and easy to operate, and it is convenient for maintenance personnel to replace it in time if a fault occurs.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the inner support 10 of the airbag is movably connected to the damper cylinder 1. The inner support 10 of the airbag works in conjunction with the energy storage airbag 8. When the energy storage airbag 8 is stretched and compressed, it does not directly contact the inside of the damper cylinder 1, but rather contacts the inner support 10 of the airbag and then presses against the stretching buffer spring 9 for auxiliary buffering. The inner partition 11 is fixedly connected to the single-outlet piston rod 2. The other end of the air supply pipe 18 is fixedly connected to the air supply port 16. The design of the air pressure sensor 12 and the drive control module 14 enables the damper's status to be monitored in real time, making it easy to detect insufficient air pressure and replenish air through the air supply port 16.

[0034] The working principle of this utility model is as follows: First, when the airbag accumulator single-pole viscous damper is taken out, its two ends are connected to external equipment via the first connector 4 and the second connector 5. Then, when the single-pole piston rod 2 is impacted, it slides into the damper cylinder 1. This causes the inner piston 6 to slide inside the damper cylinder 1, thereby compressing the fluid medium and generating resistance in the airbag accumulator single-pole viscous damper to complete the buffering. Next, when the accumulator airbag 8 slides and compresses along with the single-pole piston rod 2, it does not directly contact the inside of the damper cylinder 1, but first contacts the inner support 10 of the airbag and then presses the telescopic buffer spring 9 for auxiliary buffering. Subsequently, the air pressure sensor 12 inside the accumulator airbag 8 can monitor the internal air pressure of the accumulator airbag 8 in real time and transmit the air pressure data to the drive control module 14 via wire connection. When the internal air pressure of the energy storage airbag 8 is insufficient, the switch of the micro air pump 17 can be turned on, allowing the micro air pump 17 to replenish the energy storage airbag 8 by connecting the inlet / outlet air pipe 15 and the air replenishment port 16 through the air replenishment pipe 18. This enables the energy storage single-rod viscous damper of the airbag to monitor air pressure and provide auxiliary buffering for the airbag, thereby enhancing stability. The combined action of the telescopic buffer spring 9 and the energy storage airbag 8 makes the energy storage single-rod viscous damper of the airbag more stable when subjected to impact, reducing the vibration caused by impact. Moreover, it has strong adaptability. This design can also adjust the air pressure inside the airbag according to actual needs, thereby adapting to different working environments and requirements. Finally, after completing all the installation and use of the energy storage single-rod viscous damper of the airbag according to the above operations, the switch of the micro air pump 17 is turned off. Routine maintenance of the device is then performed. In this way, the use of the energy storage single-rod viscous damper of the airbag is completed.

[0035] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
