Description

Technical Field

[0001] This utility model relates to the field of buffer device technology, specifically to an oil-gas buffer device based on valve-controlled damping. Background Technology

[0002] During landing, aircraft, spacecraft, or heavy transport vehicles undergo a rapid transition from high-speed flight to a stationary state. This process demands not only extremely high precision and stability to ensure a safe landing but also presents immense impact challenges, placing extremely stringent requirements on the cushioning system. During the high-speed flight phase, these vehicles must maintain precise heading and altitude control to cope with complex and changing airflow conditions and potential obstacles. Once in the landing phase, they must rapidly decelerate from extremely high speeds until they come to a safe stop; the energy conversion and dissipation during this process are highly complex.

[0003] Traditional landing cushioning systems have long relied on a few relatively simple cushioning mechanisms to cope with the massive impact of landing. These mechanisms include, but are not limited to, airbags, hydraulic shock absorbers, and spring systems. Airbag systems are widely popular due to their excellent energy absorption capacity and light weight; however, under extreme environmental conditions, such as high or low temperatures, the performance of the airbag materials may be affected, significantly reducing their cushioning effect. Hydraulic shock absorbers dissipate energy through the flow of fluid. While highly effective, the complex hydraulic system requires high levels of sealing and maintenance, and repairs are difficult once a malfunction occurs. Utility Model Content

[0004] The purpose of this invention is to provide an oil-gas buffer device based on valve-controlled damping to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-gas buffer device based on valve-controlled damping, comprising a main actuator cylinder, a piston plate slidably mounted inside the main actuator cylinder, a main piston rod fixedly mounted on one side of the piston plate, a movable disk fixedly mounted on the end of the main piston rod away from the piston plate, two oil buffer outer cylinders fixedly mounted on the side of the movable disk away from the main piston rod, oil buffer piston rods slidably mounted inside the two oil buffer outer cylinders, a connecting disk fixedly mounted on the end of the oil buffer piston rod away from the oil buffer outer cylinder, a connecting rod fixedly mounted on the end of the connecting disk away from the oil buffer piston rod, and a separation pusher fixedly mounted on the end of the connecting rod away from the connecting disk.

[0006] Preferably, a connecting seat is fixedly installed at one end of the main actuator cylinder, and a connecting bolt is threaded into the internal part of the connecting seat.

[0007] Preferably, the bottom of the connecting seat is fitted with an assembly plate by connecting bolts, the assembly plate is internally threaded with assembly bolts, and the assembly plate has an air inlet hole inside.

[0008] Preferably, a reinforcing rib is fixedly installed on the outer side of the main actuator cylinder. There are four reinforcing ribs, and the four reinforcing ribs are installed in a rectangular symmetrical manner on the outer side of the main actuator cylinder.

[0009] Preferably, a rate sensor is fixedly mounted on the top of one of the reinforcing ribs, and a pressure sensor is fixedly mounted on the top of the other reinforcing rib.

[0010] Preferably, a locking nut is fixedly installed on the outer side of the connection between the connecting rod and the separating push plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when the separating push plate is impacted, the connecting rod can push the connecting plate to move, thereby pushing the oil buffer piston rod to move inside the outer cylinder of the oil buffer, thereby buffering, which can make full use of the damping effect of the oil, effectively absorb and disperse the energy from the impact, thereby achieving a highly efficient buffering effect.

[0012] The reaction force can drive the moving disc to move, thereby driving the main piston rod to move downward. In conjunction with the gas supplied by the air supply equipment to the main actuator cylinder and the piston plate, auxiliary buffering is achieved, realizing multi-dimensional absorption and dispersion of impact energy. This results in a more comprehensive and efficient auxiliary buffering function, which not only provides timely and effective buffering protection when the separation pusher is impacted, but also ensures that the entire system maintains high stability and reliability under complex and changing working conditions.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 This utility model provides a technical solution: an oil-gas buffer device based on valve-controlled damping, including a main actuator cylinder 1, a piston plate 17 slidably installed inside the main actuator cylinder 1, a main piston rod 16 fixedly installed on one side of the piston plate 17, a movable disk 15 fixedly installed at the end of the main piston rod 16 away from the piston plate 17, two oil buffer outer cylinders 14 fixedly installed on the side of the movable disk 15 away from the main piston rod 16, oil buffer piston rods 18 slidably installed inside the two oil buffer outer cylinders 14, a connecting disk 13 fixedly installed at the end of the oil buffer piston rod 18 away from the oil buffer outer cylinder 14, a connecting rod 2 fixedly installed at the end of the connecting disk 13 away from the oil buffer piston rod 18, a separation pusher 3 fixedly installed at the end of the connecting rod 2 away from the connecting disk 13, a connecting seat 5 fixedly installed at one end of the main actuator cylinder 1, a connecting bolt 6 threadedly connected inside the connecting seat 5, an assembly disk 8 installed at the bottom of the connecting seat 5 through the connecting bolt 6, an assembly bolt 7 threadedly connected inside the assembly disk 8, and an air inlet 12 opened inside the assembly disk 8.

[0019] The working principle of the above technical solution is as follows: First, the device can be installed in the required position through the assembly plate 8. Then, an external air supply device is connected through the air inlet 12. When the separating push plate 3 is impacted, the connecting rod 2 can push the connecting plate 13 to move, thereby pushing the oil buffer piston rod 18 to move inside the outer cylinder 14 of the oil buffer, thus buffering. It can make full use of the damping effect of the oil to effectively absorb and disperse the energy from the impact, thereby achieving a highly efficient buffering effect. Furthermore, the reaction force can drive the moving plate 15 to move, thereby driving the main piston rod 16 to move downward. In conjunction with the gas supplied by the air supply device into the main actuator cylinder 1 and the piston plate 17, auxiliary buffering is achieved, realizing multi-dimensional absorption and dispersion of impact energy. This achieves a more comprehensive and efficient auxiliary buffering function, which not only provides timely and effective buffering protection when the separating push plate is impacted, but also ensures that the entire system maintains a high degree of stability and reliability under complex and changing working conditions.

There are four reinforcing ribs 4, and the four reinforcing ribs 4 are installed in a rectangular symmetrical manner on the outside of the main actuator cylinder 1. A rate sensor 10 is fixedly installed on the top of one of the reinforcing ribs 4, and a pressure sensor 9 is fixedly installed on the top of the other reinforcing rib 4.

[0021] The outer side of the main actuator cylinder 1 can be reinforced by the four reinforcing ribs 4. The pressure of the device and the moving speed of the connecting rod 2 can be detected by the speed sensor 10 and the pressure sensor 9.

[0022] In another implementation scheme, such as Figures 1-3 As shown, a locking nut 11 is fixedly installed on the outer side of the connection between the connecting rod 2 and the separating push plate 3.

[0023] The locking nut 11 ensures the stability of the connection between the separating push plate 3 and the connecting rod 2.

[0024] Working principle: First, the device can be installed in the required position through the assembly plate 8. Then, an external air supply device is connected through the air inlet 12. When the separating push plate 3 is impacted, the connecting rod 2 can push the connecting plate 13 to move, thereby pushing the oil buffer piston rod 18 to move inside the outer cylinder 14 of the oil buffer, thus buffering. It can make full use of the damping effect of the oil to effectively absorb and disperse the energy from the impact, thereby achieving a highly efficient buffering effect. Furthermore, the reaction force can drive the moving plate 15 to move, thereby driving the main piston rod 16 to move downward. In conjunction with the gas supplied by the air supply device into the main actuator cylinder 1 and the piston plate 17, auxiliary buffering is achieved, realizing multi-dimensional absorption and dispersion of impact energy, thus achieving a more comprehensive and efficient auxiliary buffering function. It can not only provide timely and effective buffering protection when the separating push plate is impacted, but also ensure that the entire system maintains a high degree of stability and reliability under complex and changing working conditions. The four reinforcing ribs 4 can strengthen the outer side of the main actuator cylinder 1. The speed sensor 10 and pressure sensor 9 can detect the pressure of the device and the moving speed of the connecting rod 2.
