Description

Air damper
Technical field
The present invention relates to a kind of air dampers for automobile glove box switch, belong to technical field of automobile accessories.
Background technique
Glove box is storage space important on automobile, and utilization rate is high.Glove box is equipped with glove box lock, for controlling The open and close of glove box.The service life of glove box lock directly affects the service life of glove box, if glove box lock structure It designs unreasonable, the service life of glove box can be greatly reduced.
Air damper on glove box is generally disposed on chamber door, is opened for controlling chamber door, enables chamber door slow It opens, prevents from being pressed gravity caused by the article near chamber door and cause chamber door to hurtle down and then influence the use of chamber door The personal safety of service life and operator.In the prior art, small air inlet is set on piston or cylinder, piston rod to When outer pulling, due to sealing between piston and cylinder, the damping cavity of cylinder generates negative pressure, by small air inlet to the damping cavity Ventilation, and then generate buffering effect.The air damper of the prior art has the following problems:One, since small air inlet is arranged On piston and cylinder, size immobilizes, and therefore, the damping force size that small air inlet generates is very difficult to adjust.Two, existing Speed is nearly all at the uniform velocity, to pass through more difficult its movement velocity of adjusting of air inlet, glove box when the glove box of technology opens and closes It more should slowly be opened when opening, it should more quickly, to prevent damage glove box when closing.
Summary of the invention
For the above deficiency in the prior art, the purpose of the present invention is to provide a kind of air for automobile glove box Damper, to solve the problems, such as that automobile glove box switching speed is non-adjustable in the prior art and glove box is easily damaged.
Technical scheme is as follows:Air damper, cylinder including an end closure, setting cylinder sealing end with The air damping pull rod that the piston and one end that cylinder inboard wall matches are connected with piston, the other end of the air damping pull rod are stretched Out outside cylinder;The pull rod chamber that cylinder is divided into damping cavity and be connected with atmosphere by the piston is provided with connection on the piston The through-hole of damping cavity and pull rod chamber;Damping cavity and drawing are adjusted it is characterized in that, being provided between air damping pull rod and piston The buffer structure of air pressure between rod cavity, the buffer structure include sealing block, spring be connected on piston with setting damping cavity and The cushion hole of pull rod chamber;The sealing block passes through the spring being arranged between sealing block and air damping tie rod end and is against buffering Kong Shang.By the way that buffer structure is arranged, when glove box is opened, air is entered in damping cavity by through-hole, passes through setting through-hole Size, the speed that adjustable glove case is opened prevent glove box is firmly excessive when opening from opening rapidly to caused by, anti-to stop loss Bad glove box, when glove box is opened, the intracavitary pressure of pull rod is greater than the pressure in damping cavity, and sealing block is fitted tightly over cushion hole On, air can only be entered in damping cavity by through-hole, it is therefore prevented that the too fast problem of glove box opening speed;When glove box is closed When, the pressure in damping cavity is greater than the intracavitary pressure of pull rod, so that the gas in damping cavity passes through through-hole and cushion hole discharge resistance Buddhist nun is intracavitary, and closing velocity can constantly be adjusted according to the air pressure size in damping cavity, can close rapidly.
Cushion hole can be the structures such as circle, square, grid-shaped.
Further, baltimore groove is provided on the piston, the sealing block is arranged in baltimore groove, the cushion hole setting In spill trench bottom.By the way that baltimore groove is arranged on piston, sealing block can be prevented by the stable setting of sealing block in baltimore groove Sideslip and cause buffer structure to fail.
Further, open up fluted on the sealing block, the end of the air damping pull rod is provided with pedestal;It is described Spring one end covers on the base, and the other end is against in the groove of sealing block.By the way that groove is arranged on sealing block and in sky Pedestal is set on gas damping draw-bar, spring can be oriented and be arranged, prevent spring sideslip from buffer structure being caused to fail, structure is simple. The pedestal of air damping pull rod is cross-rib shape or circle BOSS rod structure with fixed spring one end.
Further, the piston is provided with sealing ring with the cylinder place of matching.By the way that sealing ring is arranged, through-hole can be made and delays The switch of glove box can preferably be completed by rushing structure.
Further, the open end of the cylinder is provided with end cap, and the stretching of air damping pull rod is provided on the end cap Opening.By the way that end cap is arranged, air damper can be kept more stable air damping pull rod directed movement.
Further, the air damping pull rod is mutually clamped with piston.It is arranged by clamping, repairing easy to disassemble.
Further, reinforcing rib is provided on the air damping pull rod.Reinforcing rib on air damping pull rod is diamond shape, circle The structures such as shape or quadrangle.
Further, the through-hole aperture is 0.2-0.3mm, and the cushion hole aperture is 1.8-2.0mm.It is gentle by through-hole The adjustment of punching aperture ratio, it is ensured that people can make on the whole glove box opening and closing speed suitable under most suitable dynamics.
Further, the bottom gap of sealing block and pedestal is 0.6-1mm.The groove side gap of pedestal and sealing block is 0.6-1mm.In piston motion, gap width is too small so that thrust is increased, and gap width reduces thrust greatly very much, influence glove box pass The comfort closed.
The principle of the present invention is:
1, when glove box is opened, air damping pull rod seals between sealing ring and cylinder to cylinder extracorporeal movement, prevents gas Body enters damping cavity, and spring end is against on sealing block, and sealing block seals Zhu's cushion hole, prevents gas from entering in damping cavity, only By the slow air inlet of through-hole, keep the resistance of air damper larger, to drive glove box when opening, slowly moved, Prevent glove box from quickly moving the problems such as causing glove box easily damaged and abnormal sound Caton.
2, when glove box is closed, air damping pull rod is moved into cylinder, is sealed between sealing ring and cylinder, and gas is prevented Body leaks from damping cavity, at this time sealing block stress, and compressed spring, to realize that gas is discharged, the resistance of piston is made to become smaller, from And drive glove box when closed, it is quickly moved, glove box can be closed faster.
Air damper of the invention is by setting buffer structure, and stress and speed are non-adjustable when solving glove box switch The problem of, it is therefore prevented that glove box damages when switching, and extends the service life of glove box, and structure is simple, is easy to use.
