Liquid-gas coexistence type buffering device and buffering device array

Abstract

The invention discloses a liquid-gas coexistence type buffering device. The liquid-gas coexistence type buffering device comprises an outer cylinder (1) and an inner cylinder (2). An outer cylinder inner cavity (11) used for containing buffering liquid and gas and mounting the inner cylinder (2) is formed in the outer cylinder (1). One or more outer cylinder flow limiting plates (12) are mounted on the outer cylinder (1) and located in the outer cylinder inner cavity (11). The outer cylinder inner cavity (11) is divided into a plurality of buffering chambers by the outer cylinder flow limiting plates (12). When the liquid-gas coexistence type buffering device is in use, at least one buffering chamber is filled with gas, and channels for liquid or / and gas circulation are formed in the outer cylinder flow limiting plates (12). One end of the inner cylinder (2) is movably mounted in the outer cylinder inner cavity (11) of the outer cylinder (1) in a sleeved mode. The inner cylinder (2) can move in the outer cylinder inner cavity (11) of the outer cylinder (1) in the axial direction. The liquid-gas coexistence type buffering device is wide in application range and flexible in use and can evenly distribute collision stress when collision occurs, prolong the interaction time during collision and achieve an excellent buffering effect.

Description

technical field [0001] The present invention relates to the technical field of buffer devices, in particular to a buffer device and a buffer device array that can effectively prolong the interaction time of impacts in the direction of motion and thus play an excellent buffering role in coexistence of liquid and gas. Background technique [0002] With the development of science and technology, people's living standards continue to improve. Modern tools such as cars, elevators, and object transport lifts that replace people's transportation or reduce labor intensity have entered people's daily lives, bringing great benefits to people's daily travel and work. Great convenience, but also promote the rapid development of all walks of life. [0003] However, cars, elevators, etc. are running faster and have greater inertia, and because of human subjective factors and failures of electromechanical components, accidents such as collisions with other objects often occur, while cars, ...

Problems solved by technology

But both devices have significant limitations:

[0005] 1. The bumper is a kind of hard collision device, which only reduces the degree of damage to the front of the vehicle (and other sports tools, the same below, and will not repeat it), but does not reduce the impact force for the entire impact, that is, after the impact, the impact on the entire The injury of the vehicle and the personnel inside the vehicle has not been reduced, and basically has no protective effect; the bumper may even increase the degree of injury to the personnel inside the vehicle. The bumper is a hard collision protection device, which will reduce the time of the collision process and form a stronger Hard collision situations, that is, although the bumper can protect the integrity of the front of the vehicle to a certain extent, it will actually cause more damage to the occupants of the vehicle

[0006] 2. The entire process of airbag explosion activation has a time lag. It is often after the second collision of the human body that the gas formed by the airbag explosion is generated, that is, the rescue is often "started after being injured", and the impact of the airbag explosion Force can cause new damage to personnel

Therefore, the anti-collision equipment combined with the bumper and the airbag is often difficult to protect the safety of the people on the vehicle, and countless accidents have proved this point
