THE RELATED ART

Invention relates to the system which controls opening-closing in the car such as engine hood, trunk or 5 ^th door etc. and also provides advantages in respect to efficiency in work and workmanship, time, material processing and other similar factors in production.

BACKGROUND OF THE RELATED ART

There are two type of gas springs in today’s vehicles; hydraulic damping and dynamic damping ones. The biggest problem with hydraulic damping gas springs is that they may work unilaterally because dampening oil remains at the bottom when gas spring is turned upside down (for example in vehicle trunk which opens more than 90). To eliminate this problem dynamic damping gas springs were developed. Hydraulic damping gas springs have holes on piston for letting air and oil move accordingly. Oil and gas transferring are provided by the ring located on the gas spring as a check valve. Engraved channel (groove) helps gas spring a more controlled and slowed down air pass. In dynamic gas springs there is no need of a hole because the function of the hole is provided by the groove engraved on gas spring’s tube. In this case, air pass is provided between Teflon ring on the piston through groove inside the gas spring’s tube instead of holes on the piston. With this application even opposite direction openings, gas spring work properly. However, the problem here relates to processing of groove inside gas spring’s tube. This groove must be machined very delicately. In case of a slight fluctuation in groove, speed of air-pass will change and thus piston become instable as it is working. Scratches etc. inside the tube cause too much waste and failure to achieve required quality. Moreover, in dynamic pistons Teflon ring should be used to eliminate the rubber O- ring misfunctioning (closing the groove) in the piston or get deformed by groove and become incapable to perform its function. Even though Teflon might be a solution, but it also has some disadvantages. It is too expensive, it is difficult to insert Teflon into the tube and during groove engraving in the production egg shape might occur and when it is inserted into piston spindle, it causes empty spaces and moving. It is considered as dangerous and not in good quality for consumers and the system being subject thereof is developed under application numbered TR2018/16733 to solve current problems. However, some problems are encountered in the system disclosed under application numbered TR2018/16733 and production of small hole required to be provided on Gas Spring’s rod is slowed down.

In conclusion, the problems mentioned above and not solved in the light of related art have necessitated novelty in the related art.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, novelty being subject of this invention has been disclosed solely for the purpose of better understanding of the subject and with samples described in a manner not causing any restrictive effect. The invention relates to a gas spring assembly(A) consisting of a piston (5) functioning as housing and sealing, an gas spring’s tube functioning as outer protector and pressure chamber, a felt preventing flow of gas out of gas spring’s tube, an gas spring rod (2) moving inside gas spring’s tube, a dynamic damping speed hole (a) located on the gas spring rod (2) and setting speed of slowing operation of damping based on diameter, rod inside channel (b) providing discharge of air passing through said dynamic damping speed hole (a) to other side of piston (5) and provided inside gas spring rod (2), a bearing bush providing bearing of the gas spring rod (2), O-ring (4) surrounding inner wall of gas spring’s tube in respect to working direction of it and moving in two-directions and thus allowing or preventing air passage, clover washer (3) consisting of return channel (3.1 ) functioning as path providing return air during closing of gas spring assembly (A), preventing sliding down of O-ring (4) and speeding up upward movement of O-ring (4), brake bush (1 ) staying constant inside gas spring’s tube, allowing passage of gas spring rod (2) through it and providing gradual closing of dynamic damping speed hole (a) and thus providing speed control, changing amount of air thanks to its flat or conic assembly and providing fast, slow, stable or gradually slowing (ramped) completion of opening of Gas Spring assembly (A). Thus, the system consists of a piston speed hole (c) opening on the piston (5) in a manner to combine with said rod inside channel (b) and setting out speed of gas spring assembly (A) according to hole diameter.

In the system disclosed under this invention, said piston (5) can also be produced in uniform form to contain clover washer (3). In the system disclosed under this invention, piston speed hole (c) is preferably located in the centre of piston (5) component.

Figure 1 and Figure 2 show damping status of the system disclosed under the invention and views of detail A (Detail-A) and detail b (Detail-B). when dynamic damping speed hole (a) located on gas spring rod (2) goes into brake bush (1 ), gas (N) inside gas spring’s tube passes through space between brake bush (1 ) and gas spring rod (2) and dynamic damping speed hole (a) located on the gas spring rod (2) and thus discharge is completed. Speed of gas spring assembly (A) decreases because of conical assembly of the brake bush (1 ). This decrease occurs on side of piston speed hole (c). speed of gas spring assembly (A) decreases by slowing down until clover washer (3) rests on brake bush (1 ). Thus, damping assembly (A) makes damping as in hydraulic and dynamic damping in last opening area.

Figure 3 shows opening status of and detail C (Detail-C) and detail D (Detail-D) views of the system disclosed under this invention when the gas spring assembly (a) in close position is released, it goes into opening position and gas spring rod (2) starts to move in -x direction. During that time, O-ring (4) rests onto the piston (5) and prevents flow of gas to back chamber from piston (5) via gas spring’s tube. In this case, the gas (N) passes through damping speed hole (a), Rod inside channel (b) and on the gas spring rod (2) and through piston speed hole (c) on the piston (5) completes discharge damping speed hole (a) and Rod inside channel (b) are characterized in that they have same diameter damping speed hole (a) and Rod inside channel (b) diameters are bigger than diameter of piston speed hole (c). Speed of gas spring assembly (A) is restricted by piston speed hole (c) and it continues at constant speed until damping speed hole (a) enters brake bush (1 ).

Figure 4 shows closing status of and detail E (Detail-E) and detail F (Detail-F) views of the system disclosed under this invention. When the gas spring assembly (A) in open position is pressed, it goes into closing position and gas spring rod (2) starts to move in +x direction. During that time O-ring (4) rests on clover washer (3). Thus, the area between piston (5) and gas spring’s tube opens and flow of gas from back chamber to front chamber is provided. During that time some amount of gas (N) flows to front chamber through piston speed hole (c) located on piston (5) and damping speed hole (a) located on gas spring rod (2) and rod inside channel (b).
