Abstract

The present invention provides a moving body shock absorbing device using a damper for increasing the rate of a change in braking force to a change in the speed of a piston to enlarge an adaptable range. The piston consists of an inner member integrated with a piston rod and an outer member mounted on the outer periphery of the inner member movably in the axial direction. Both the inner and outer members are loosely fitted to each other in a cavity G where viscous fluid flows, and they are resiliently energized to directions of spacing each other by a compression coil spring (a second compression coil spring). As the protrusion of the inner member into the outer member is greater, the cavity between both of them is narrower. A cylinder is fixed to one of colliding portions of both the moving body and a movement restricting part for restricting the movement of the moving body with the abutment on the moving body, and the piston rod is pushed by the other colliding portion to force the piston into the cylinder.

Description

Absorb the device of the impact of moving body

Technical field

The present invention relates to use piston to be slidingly matched with having aperture, and the device of the impact of the absorption moving body of the inner oil hydraulic cylinder that has encapsulated viscous fluid.

Background technique

For door of preventing the room and so on produces impulsive sound when the quick closedown, and the buffer of the speed that reduces to close the door being set on the door next door in room, is known.

As the buffer of this generation braking force, known buffer has following each several part usually: inside is packaged with the oil hydraulic cylinder of viscous fluid; With oil hydraulic cylinder inside separated into two parts vertically, and has the piston of the aperture of axial connection; And be connected piston rod on the piston; And, piston with piston rod in oil hydraulic cylinder in axially movable process, the braking force that produces by means of the resistance of viscous fluid the time (making the power of motion decay) by aperture.(referring to No. 3465978 patent gazette of patent documentation 1-)

Above-described buffer, the characteristic of all utilizing the flow resistance of viscous fluid to increase along with the raising of piston traveling speed proportionally.For example, when as the door damping device the time, its structure can do be paired in close slow in one's movementsly the door resistance little, and for the action close hastily the door braking force big.

; braking force is to set by the diameter that is arranged on the aperture on the piston specially; when it is set at steering force when being suitable for low speed; braking force during high speed just has big inadequately tendency; in contrast; during braking force when it is suitable for high speed, will produce the problem of the operating characteristics that is unfavorable for low speed.In a word, it is inconvenient making the dynamic range expansion of braking force.

Summary of the invention

For addressing the above problem, a kind of ratio that increases braking force with respect to the variation of velocity of piston is provided, can enlarge the buffer of the scope of its adaptation, in first scheme of the present invention, a kind of like this buffer is provided, in the sort buffer device, it uses the piston (4) of the aperture (13) with axial connection, inside has been encapsulated the oil hydraulic cylinder (3) of viscous fluid along its axial separated into two parts, and, piston be connected thereon piston rod (5) in oil hydraulic cylinder in axially movable process, resistance by means of the viscous fluid by aperture produces braking force, it is characterized in that, above-mentioned piston is by making the inner piece (4a) of an integral body with piston rod, can on the excircle of inner piece, be constituted with being mounted to along axially movable exterior part (4b), these two inner pieces and exterior part are chimeric mutually, can relatively move, be provided with the space (G) that viscous fluid can flow between the two, and, the elastic force that is produced by means of compression helical spring (second compression helical spring) leaves both mutually, when the inlet in inner piece enters exterior part increased, above-mentioned space just reduced.

In addition, above-mentioned oil hydraulic cylinder is fixed on moving body (30) and by being crimped on either party the collision part of the restriction moving part (40) that moves in the two that limits this moving body on this moving body, partly push above-mentioned piston rod by collision, above-mentioned piston is compressed into above-mentioned oil hydraulic cylinder with the opposing party.

This structure according to first scheme of the present invention, under the lower state of the travelling speed of piston rod, utilize the elastic force of compression helical spring, the space between inner piece and the exterior part remains under the bigger state, because viscous fluid keeps lower flow resistance and can not damage operating characteristics.And when the travelling speed of piston rod surpasses the value of regulation, when the resistance that acts on the viscous fluid on the exterior part surpassed the tensile force of compression helical spring, helical spring shrank, and inner piece just enters in the exterior part.So the space between inner piece and the exterior part just diminishes, make the flow resistance of the viscous fluid by this space further increase, thereby produce very big braking force.That is, according to the present invention, the ratio that the braking force that takes place with respect to the variation of velocity of piston changes has increased, and aspect the Applicable scope that enlarges buffer, can obtain very big effect.

In addition, adopt the device for impact absorbing of the moving body that has used the described buffer of first scheme of the present invention, the impact of the moving body of decaying, thus can reduce noise that is produced or the like.

Embodiment

(buffer 1)

Below, present invention will be described in detail with reference to the accompanying.

Fig. 1 is to use the sectional view of buffer of the present invention.Sort buffer device 1 is made of following each parts: the bottom surface is sealed, and the oil hydraulic cylinder 3 of yielding rubber 2 has been installed on its outer end; Be slidingly fitted in the piston 4 of oil hydraulic cylinder inside; Be connected the piston rod 5 on the piston 4; Be arranged between the diapire internal surface of spring retainer (baffle plate) 6 on the inner of being located at piston rod 5 and oil hydraulic cylinder 3 first compression helical spring 7 that is compressed; Be arranged on the accumulator 8 of oil hydraulic cylinder top one side; The lid 9 of plugging fluid cylinder pressure open-topped.By oil sealing 11, the piston rod 5 that passes the center hole 10 of lid 9 protrudes the outside at oil hydraulic cylinder 3.In addition, in oil hydraulic cylinder 3 inside, encapsulated the suitable silicone oil of viscosity.

(piston 4)

Piston 4 is made of inner piece 4a and exterior part 4b, in fact inner piece 4a becomes as a whole with the inner end of piston rod 5, exterior part 4b activity is inlaid on the inner piece 4a, separates predetermined space G with the outer peripheral surface of inner piece 4a, and is slidingly matched with the inner peripheral surface of oil hydraulic cylinder 3.Between inner piece 4a and exterior part 4b, second compression helical spring 12 that both is applied elastic force is installed, it is axially leaving both.Here, the size of inner piece 4a external diameter is step-like variation, and the outer end is done greatlyyer, and when inner piece 4a entered the amount increase of exterior part 4b inside, the space G between inner piece 4a and the exterior part 4b just narrowed down.In addition, exterior part 4b makes the cylindrical shape at the end, is formed for making the aperture 13 of the appropriate diameter that silicone oil flows through on its diapire.

Accumulator 8 usefulness have the elastic force of appropriateness, and make cylindrical shape with the foamed synthetic resin material that just shrinks when applying predetermined pressure, remain on by means of retainer 14 on the inner peripheral surface of oil hydraulic cylinder top one side.

The working principle of buffer of the present invention then, is described.

Usually, as shown in Figure 1, piston rod 5 utilizes the elastic force of first compression helical spring 7, outwards protrudes from the center hole 10 of lid 9.In addition, the exterior part 4b of piston 4 keeps off on the spring retainer 6 that is arranged on piston rod 5 inner sides with the elastic force of second compression helical spring 12, prevents that it from coming off.

In addition, oil hydraulic cylinder 3 for example, utilizes that proper device is fixed on the room side wall inner surfaces.

When the door in room when under this state, closing at leisure, be pressed in the elastic force that piston rod 5 on the internal surface just overcomes first compression helical spring 7, be pressed in the oil hydraulic cylinder 3.In this process, the silicone oil of bottom just passes through the aperture 13 of exterior part 4b of piston 4 and the space G between exterior part 4b and the inner piece 4a, flows to the top, and the energy that the flow resistance of the silicone oil of this moment is applied on the piston rod 5 reduces gradually.In this state, because exterior part 4b and inner piece 4a leave mutually because of the elastic force of second compression helical spring 12, make to have kept broad space between exterior part 4b and the inner piece 4a, thereby braking force remains in the small range.

In the time of in piston rod 5 enters oil hydraulic cylinder 3, though oil hydraulic cylinder has reduced this a part of internal capacity, the confining pressure of silicone oil has been increased, the compressive strain of these accumulators of all being made with synthetic resin foam 8 absorbs.

Then, because the flow resistance of silicone oil increases with respect to the velocity of piston progression, for example, when the speed of setting piston 4 surpassed some speed, the resistance that silicone oil is applied on the exterior part 4b in the time of just utilizing piston 4 to move compressed second compression helical spring 12, then because when surpassing this speed, the dyskinesia of exterior part 4b, second compression helical spring 12 just is compressed, so, just as shown in Figure 2, inner piece 4a just enters in the exterior part 4b.So, because the space G between exterior part 4b and the inner piece 4a diminished, so, just improved by the braking force that flow resistance caused of silicone oil.

Like this, according to the present invention, owing to used the compression helical spring 12 that can experience the braking force transfer speed that causes by variable orifices, thus can adopt for the smaller structure of the variation of the transfer speed that causes because of the ambient atmosphere variation of temperature.

In addition, owing to utilized two along 2 parts that axially relatively move, be that space G between inner piece 4a and the exterior part 4b constitutes variable orifices, thereby can enlarge amplitude of variation with the corresponding damping force of velocity variations of piston rod 5, thereby can improve the degrees of freedom of the performance characteristic that sets.
