Abstract
The utility model relates to a gas spring of a vehicle seat, which comprises a piston rod, a cylinder barrel, a guider, a seal ring, a locating sleeve, a piston, a needle valve, a flow valve, a floating piston, a piston rod assembly and an oil distribution device, and further comprises a base, a slide valve and a rubber ring, wherein the base and the slide valve are mounted at the other end of the cylinder barrel; the front and the rear sections of the slide valve adopt a big cylinder and a small cylinder; an annular groove is formed on the end surface of the big cylinder at the joint of the big and the small cylinders; the front end of the base is a cylinder and mutually combined with an inner hole of the cylinder barrel, and two gradually reduced counter bores are formed in the lateral center at the front end of the base; a spigot excircle is arranged at the middle end of the base, and one end surface of the cylinder barrel is connected with the end surface of the spigot excircle; and a screw rod is arranged at the rear end of the base, and a through hole is formed at the lateral center of the base. The gas spring of the vehicle seat has the advantages of simple structure and reliable sealing performance, and is easy to manufacture.
Description
Technical field
The utility model relates to a kind of auto use chair air spring.
Background technique
The seat air spring mostly is used for supplying on the passenger vehicle passenger to sit the backrest seat that can recede and can rebound automatically.The epicoele of seat air spring, that is two chambeies up and down of piston assembly are to be the power transmission medium with hydraulic oil; The cavity of resorption of seat air spring, that is the chamber of floating piston assembly and base assembly formation is to be the power transmission medium with gas.
The base of seat air spring was a single piece in the past, generally two kinds of aspects are sealed in the inflation of seat air spring again: one, pressurized gas are inflated to the cavity of resorption of seat air spring from the aperture of base, iron and steel with the hole diameter that is slightly larger than base is pressed in the aperture of base again, seal pressurized gas in the seat air spring in the mode of interference fit, this has just brought four problems: when 1, the aperture of base is too small, easily cause being pressed into the cracked of steel ball, even the steel ball difficulty is pressed into.When 2, the aperture of base is excessive, easily cause the pressurized gas in the seat air spring outwards to be revealed.After in case 3 steel balls are pressed into the pressurized gas of sealing in the seat air spring, just can not make-up gas, that is can not adjust the size of the interior high-pressure gas pressure of seat air spring, can cause the defective of part seat air spring product.When 4, inflating, need special device, and efficient is lower.Two, seal pressurized gas in the seat air spring with the form of one-way valve in base, mostly adopt a little steel ball and a pressure spring, but the roughness required precision of steel ball and the junction plane of base is than higher, manufacture cost is corresponding also bigger.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, good seal performance and auto use chair air spring safe in utilization.
The technical solution of the utility model is achieved in that a kind of auto use chair air spring, it comprises piston rod, cylinder barrel, guider, seal ring, setting sleeve, piston, needle-valve, flowing valve, floating piston, piston rod assembly and distributing device, it also comprises base, guiding valve and rubber ring, base, guiding valve is installed in the end in addition of cylinder barrel, the front and back of guiding valve are small one and large one cylindrical body compositions for two sections, end face at big small cylinder junction large cylinder has circular groove, the front end of base is a cylindrical body, cooperatively interact with the endoporus of cylinder barrel, have two counterbores from big to small in its transverse center, the middle end of base is provided with the seam cylindrical, one end face of cylinder barrel and seam cylindrical end face join, rear end at base is provided with screw mandrel, has a through hole in the transverse center of base.The utility model has the advantages that: simple in structure, easily to make, sealability is reliable.
