Abstract
The utility model relates to an automatically brace device of a rolling door and a window of a car, particularly a hydraulic pneumatic brace strut. Because the utility model adopts the structure of a hydraulic pneumatic linkage and a one-way valve, the capability is advanced compared with an existing pneumatic brace strut, and the action is smooth, slow and without concussion. On the aspect of the service life, because the order that oil seals gases and then is sealed by a sealing ring, the utility model is safer than a device which uses the sealing ring to directly seal high-pressure gases, and the service life is long. The hydraulic pneumatic brace strut can be used for not only the car but also any rolling door and window.
Description
The utility model relates to automatic bracing or strutting arrangement--the hydropneumatic strut of convertible door and windows such as a kind of automobile, it is owing to used airdraulic operating principle and structurally be provided with one way valve and damping hole, make its strut action smooth-going gentle slow than existing pure pneumatic type, and gases at high pressure are difficult for leaking, and the life-span is longer.
Operating principle of the present utility model and structure description following (referring to accompanying drawing):
1, the two ends of cylindrical shell 9 and front head 3 and rear head 12 riveting mutually, the middle part is provided with the piston 10 that moves about, ante-chamber (A chamber) fills gases at high pressure 11, the damping hole of one one way valve and a minor diameter is set on piston 7, when external force was pressed into piston rod 1, one way valve (being made up of metal coil spring 4 and steel ball 5) was opened, and hydraulic oil rises by unidirectional valve opening and damping hole, piston descends, and the volume that piston rod 1 enters in the cylindrical shell 9 is adjusted by the piston compression gases at high pressure that move about.When external force during less than the outer top power of piston rod, gases at high pressure upwards promote to move about piston 10, thereby compression hydraulic oil makes piston rod overhanging, reaches the effect of opening and supporting door, window.
2, after the B chamber charged into gases at high pressure, steel ball 5 was with the air-filled pore sealing, and the outside rivets with rivet again, and cylindrical shell 9 is also riveted tightly after adorning O-ring seals with the joint of rear head 12, and like this, gases at high pressure just can not be leaked outside by the rear portion.Owing to adopted the piston that moves about, made the oil pressure on its both sides and air pressure keep equating that the sealing of zero RunddichtringO is arranged on the piston that moves about in addition.Therefore, gases at high pressure 11 are difficult for entering the A chamber by the piston that moves about and leak, and this just will insure than existing pneumatic strut sealing gas, and then the life-span is longer.

Claims (2)
1, a kind of hydropneumatic strut of forming by piston rod 1, O-ring seals 2, front head 3, metal coil spring 4, steel ball 5, O-ring seals 6, piston 7, hydraulic oil 8, cylindrical shell 9, the piston 10 that moves about, gases at high pressure 11, rear head 12, rivet 13, it is characterized in that gas-liquid linked, promptly be provided with the piston that moves about at the middle part of cylindrical shell 9, gases at high pressure and hydraulic oil are separated in two chambeies, ante-chamber (A chamber) dress hydraulic oil, after filling gases at high pressure, shuts back cavity (B chamber), in order to avoid gas leakage.
2, by the described device of claim 1, be provided with one way valve and damping hole at the middle part of piston 7, when being pressed into piston rod 1, one way valve is opened, when gases at high pressure promotion piston rod was overhanging, hydraulic oil only flowed by damping hole, the overhanging speed of piston rod is restricted and smooth-going gentle delaying.
