Description
Technical field
The utility model relates to a kind of spring, specifically is meant a kind of automotive seat damping pneumatic spring.
Background technique
Existing automobile seat damping spring (also claiming vibration damper), common have mechanical type, hydraulic type and three kinds of modes of pneumatic-typed, and mechanical type is for the most traditional common, and its cost is lower, but because rigidity is too high, and damping effect is bad, and working life is short; The hydraulic type vibration damper comprises cylinder and piston, piston head or bottom have an air chamber, use the bolt fitted seal, utilize air pressure to come damping during use, the damping of this type has overcome mechanical shortcoming, also have the long advantage of damping stroke, but its rigidity still is higher, damping effect deficiency, and inconvenient maintenance.Occurring the pneumatic-typed damping spring in recent years again is the air damping spring, a kind of pneumatic spring that is used for automotive seat is disclosed as the website publication number CN201250875Y of State Intellectual Property Office, this patent utilization air bag carries out damping, what but it adopted is to utilize the straight-tube air bag, volume is bigger, and damping effect is not good.
The model utility content
The technical problems to be solved in the utility model is, provides that a kind of volume is little, rigidity is low, the automotive seat damping spring of good damping effect.
Technical solution of the present utility model provides following a kind of automotive seat damping spring.
A kind of automotive seat damping pneumatic spring, comprise air bag, loam cake and lower cover, the two ends up and down of air bag are sealedly and fixedly connected with loam cake and lower cover respectively, described lower cover has suction port, loam cake and lower cover are respectively equipped with mounting hole and following mounting hole, the lower end of described air bag inwardly folds into, and lower cover is wrapped up by air bag and becomes piston cylinder operator with balloon-shaped.
Adopt above technological scheme, described air bag inwardly folds into, reduced the volume of spring, owing to utilize air bag damping and air bag and lower cover to form piston cylinder operator, during use, be installed in automotive seat damping pneumatic spring of the present utility model at the bottom of the automotive seats seat support and between the compartment, to in air bag, inflate by suction port then, in use, the size of and impulse force stressed according to automotive seat, lower cover will be done piston motion up and down in air bag, thereby automotive seat damping spring rigidity is low, good damping effect.
As preferably, also comprise front band and lower catch hoop, the upper end of described air bag is sealedly and fixedly connected to adopting clip to fixedly connected with loam cake, the upper end and the loam cake of air bag are sealedly and fixedly connected with front band, the lower end and the lower cover of air bag are sealedly and fixedly connected with lower catch hoop, the employing clamp band type is fixedly connected, and is fixing reliable, good sealing effect.
Further improve, be covered with the loam cake annular groove on described, be covered with the lower cover annular groove under described, the position of described loam cake annular groove and lower cover annular groove lay respectively at front band and lower catch hoop below, by reliability and the sealing that this groove can further improve clip connected is set.
As improvement, described lower cover has stiffening rib, because lower cover is stressed big, but makes lower cover load performance improve by stiffening rib is set.
In sum, air bag of the present utility model lower end inwardly folds into, and makes the volume of spring reduce, and utilizes air bag damping and air bag and lower cover to form piston cylinder operator, thereby makes that automotive seat damping spring rigidity is low, good damping effect.In use, earlier the automotive seat damping spring is installed between car seat base and the compartment, after installing, inflate in the damping spring air bag by suction port, in use, the size of and impulse force stressed according to automotive seat, lower cover will be done piston motion up and down in air bag, effectively guaranteed the damping performance of automotive seat, the utlity model has that volume is little, rigidity is low, the advantage of good damping effect.
