Abstract
The invention discloses a flexible liquid damper for a car door moving component for a top grade car, wherein the flexible liquid damper consists of a damper guide cylinder 2, a damper regulator 3, a liquid flow controller 4 and a regulating rod 1, wherein the damper regulator 3 moves axially opposite to the guide cylinder in the guide cylinder; the damper guide cylinder is internally provided with a transition groove with at least one cross section which changes continuously or discontinuously; and the liquid flow controller is provided with at least one valve, and liquids flow through the valves, thus the functions of buffering and vibration reduction of the device are realized.
Description
Technical field
The present invention relates to a kind of high-grade car door closing damping device.The liquid regulator that has a damper guide cylinder and axially move at this damper guide cylinder, this regulator have at least one ring plate that is used for can doing at this liquid condenser the piston compression movement.
Technical background
The flexible liquid damper is mainly used in the movable part of high-grade car door closing;, it can carry out slow motion like car door when being closed to the last stage; Can prevent owing to closing force causes door-plate to clash on car too greatly, influence the working life of sedan door and alleviate ambient noise.
According to present method for using; This flexible liquid damper is installed on the movable part of sedan door; At closing of the door during to last stage; Thrust will act on the adjustable lever, and the liquid in the guide cylinder is given a reciprocal active force, thus the speed when slowing down closing of the door and fundamentally avoided existing damper because high speed closed door damping buffering weak effect and loud phenomenon through the fast-assembling liquid regulator.
Summary of the invention
The objective of the invention is, invent a kind of flexible liquid damper of above-mentioned said type, thereby realize that sedan door closes the effect of closing that can reach slowly soft when closing.
According to the object of the invention, one or one group of ring plate are set, but ring plate there is the through hole filter liquide; Ring plate is connected on the adjustable lever of a circle; This device is sealed in the damping guide cylinder of a long tubular, and when adjustable lever was done the piston compression movement vertically, the liquid part in the guide cylinder flowed out from through hole and forms back pressure; Adjustable lever is moved along the guide cylinder oral area, thereby make the car door movable part play the effect of bumper and absorbing shock.
The embodiments of the invention regulation, but the ring plate compression set is elastic movement in movement process, and its structural requirement closed pore elastomeric objects can be that foam body also can be that other material constitutes.
Preferably be provided with three or four elastomers.
Description of drawings:
By description of drawings embodiments of the invention are described below: in the accompanying drawing:
Fig. 1. Fig. 2. Fig. 3 is the STRUCTURE DECOMPOSITION figure according to liquid condenser among the present invention
Fig. 4 is the original state of this liquid condenser when not receiving external active force
Fig. 5 receives among the figure during axial pressure of the direction of arrow for this liquid condenser, and the ring segment that its adjustable lever and adjustable lever are complementary direction of arrow in scheming is done the piston compression movement, and according to stressed size, its nose motion has different state.
Fig. 6 is this liquid condenser when the pressure of the direction of arrow reduces in receiving from figure, because its opposition that receives through compressed liquid forces the damped sleeve oral area motion in figure of this elastic device.
Fig. 7 for this liquid condenser stressed when reducing, because the opposition of compressed liquid forces this elastic device recovery Fig. 1 not receive external force to make the original state of time spent until complete obiteration.
Embodiment:
Form by: adjustable lever 1 and sleeve 2. damping plugs 3. exterior seal rings 4. inner seal rings 5. sponge washers 6. filter sheets 7. 9 of super link 8. Adjusting rings according to flexible liquid damper of the present invention
According to embodiments of the invention be: according to shown in Figure 4: Fig. 4 is the flexible liquid damper device of a loading liquid. Fig. 4 is this device residing original state when not receiving external active force.When this device receives external active force, as shown in Figure 5: as, at first to do the piston compression movement through adjustable lever 1 axis same and the super link 8 that is complementary and Adjusting ring 9 direction of arrow in scheme with it when receiving one in figure during the active force of the direction of arrow.Super link 8 and Adjusting ring 9. adjustable levers 1 speed and the degree of depth of arrow direction in scheme depends on the size from Fig. 5 direction of arrow active force.Shown in Figure 6 for when it receives external active force and reduces, this liquid condenser is because the reaction force of liquid compression forces Adjusting ring 9. super link 8. adjustable levers 1 past arrow direction shown in Figure 4.Fig. 7 for this liquid condenser stressed when reducing until complete obiteration Adjusting ring 9. super link 8. adjustable levers 1 reply the original state of Fig. 1 when not stressed, and in the sleeve 2 liquid when opposition liquid not toward leaking and preventing external gaseous state. in materials such as the liquid state entering guide cylinder.Be that acting in conjunction is accomplished by damping plug 3. exterior seal rings, 4. inner seal ring 5. sponge washers, 6. filter sheets 7.
