The buffer object includes fluid (in such as Fig. 5 and Fig. 6 with several stains to be diagrammatically denoted by buffer object).Wherein,
The channel 50 of the piston 24 and the channel 48 of the pedestal 28 can be to allow the buffer object to pass through.Wherein, the control piece
30 and the elastic component 32 be located at the pedestal 28 channel 48 passway E1 and the piston 24 channel 50 passway E2 between.
The inner wall 38 of the shell 22 has in one first internal diameter S1 and one second from the top of the shell 22 42 to bottom 40

42 sequentially have first internal diameter S1, the second internal diameter S2 and third internal diameter S3 to bottom 40.Wherein, first internal diameter S1 is big
In second internal diameter S2, and the second internal diameter S2 is greater than third internal diameter S3.According to this configuration, which generally can
The buffering effect that leading portion, middle section and latter end have gradually layer is enough provided.
Furthermore, which is connected to second side 24b of the piston 24 by the extension 52.On the other hand,
The control piece 30 and the elastic component 32 can be along the extension 52 and in the channels 50 in the channel of the pedestal 28 48 and the piston 24
Between activity.In addition, the channel 50 of the piston 24 is connected to the first side 24a and second side 24b of the piston 24.
As illustrated in figs. 7 and 8, when relative displacement between the piston 24 and the shell 22 generates a buffer speed, example
Such as one of the piston 24 and the shell 22 relatively another displacement therein when, the buffer unit 20 can provide buffering make
With.Wherein, in response to different situations, which can produce different buffer functions.In this embodiment, with the piston
24 receive a strength (or external force) by the extension 26, for being displaced the piston 24 with respect to the shell 22.
In the first situation, such as when the extension 26 or the piston 24 are applied one first strength F1, for example, this
One strength F1 has a First Speed, which can be sequentially by above-mentioned first internal diameter S1, the second internal diameter S2 and third
In room 36 defined in diameter S3 (piston 24 is only painted in Fig. 7 and Fig. 8 and is in room defined in the second internal diameter S2 latter end
For in 36), in the process, the buffer object positioned at aforementioned second area R2 (is come in such as Fig. 7 and Fig. 8 with several stains
It is diagrammatically denoted by buffer object) it responds the first strength F1 and is flowed towards aforementioned first area R1, and generate one first
To amount of stress F1 '.Specifically, the fluid of the buffer object can be flowed to from the region of second side 24b of the piston 24
The region of first side 24a of the piston 24 is using as first couple of amount of stress F1 '.In this, the fluid of the buffer object can
It is flowed out from the passway E1 in the channel of the pedestal 28 48, then passes through the channel 50 of the piston 24 and the periphery of the piston 24 respectively
Gap between the inner wall 38 of the shell 22 and the region for reaching the first side 24a of the piston 24.Wherein, the control piece 30 with
The elastic component 32 can be driven and the passway E1 far from the pedestal 28 and leading to towards the piston 24 by first couple of amount of stress F1 '
Road junction E2 is close, passes through the channel of the piston 24 to control the fluid of the buffer object from second side 24b of the piston 24
50 and reach the first side 24a flow.In other words, which being capable of leading to according to the buffer speed and towards the piston 24
Road 50 is displaced.Wherein, the elastic component 32 respond the buffer speed and generate an elastic force, such as the elastic component 32 it is movable to against
In a surface 55 of second side 24b of the piston 24.It follows that the buffer unit 20 because should the first situation can generate
The first buffer function.Wherein, which responds the displacement of the piston 24 and accumulates an elastic force, can use after elastic force release
The piston 24 and the shell 22 are reverted to above-mentioned buffering readiness shown in fig. 5.
As shown in Figures 9 and 10, in second of situation, such as the extension 26 or the piston 24 are applied one second power
When measuring F2, such as the second strength F2 has a second speed, which is greater than First Speed, which can be sequentially
By (being only painted in Fig. 9 and Figure 10 in room 36 defined in above-mentioned first internal diameter S1, the second internal diameter S2 and third internal diameter S3
For the piston 24 is in room 36 defined in third internal diameter S3), at this point, aforementioned buffer object is (in such as Fig. 9 and Figure 10
Buffer object is diagrammatically denoted by with several stains) it responds second strength F2 and can generate contend with therewith one second pair
Amount of stress F2 '.Specifically, the fluid of the buffer object can flow to this from the region of second side 24b of the piston 24
The region of first side 24a of piston 24 is using as second couple of amount of stress F2 '.Wherein, the control piece 30 and 32 energy of elastic component
It reaches and passway E1 far from the pedestal 28 is driven by second couple of amount of stress F2 ' and the passway E2 towards the piston 24 is close,
Preferably, the control piece 30 can respond second couple of amount of stress F2 ' and one of second side 24b in the adjacent piston 24 pre-
X is set in positioning, and the control piece 30 is enable at least partially or fully to close the channel 50 of the piston 24 in predetermined position X, with control
The buffer object is made by the flow in the channel 50 of the piston 24, and cushion effect is enabled to increase, which responds the control
Part 30 is located at predetermined position X and accumulates an elastic force F3.Also that is, the control piece 30 can be local or complete according to the buffer speed
Portion closes the channel 50 of the piston 24, passes through the flow in the channel 50 of the piston 24 to control the buffer object.For example, when should
When second couple of amount of stress F2 ' is applied to the control piece 30, if the control piece 30 has closed the channel 50 of the piston 24, it can be reduced
Or it blocks the buffer object and the work is reached by the channel 50 of the piston 24 from the region of second side 24b of the piston 24
The flow in the region of the first side 24a of plug 24.Therefore, under the case where control piece 30 closes channel 50 of the piston 24,
After the passway E1 in the channel of the pedestal 28 48 outflow, the fluid of the buffer object is the fluid of the buffer object
The area of the first side 24a of the piston 24 is reached by the gap between the periphery of the piston 24 and the inner wall 38 of the shell 22
Domain, damping force is very big at this time；On the other hand, which is resiliently deformed because being resisted against surface 55 of the piston 24, and
Accumulate elastic force F3.It follows that the buffer unit 20 because should second of situation can generate second of buffer function.
In the third situation or a predetermined buffer situation, when the piston 24 is in above-mentioned first internal diameter S1, the second internal diameter
It (in Fig. 9 and Figure 10 is only painted the piston 24 in room 36 defined in S2 or third internal diameter S3 and is in third internal diameter S3 and determine
For in the room 36 of justice) and (in this third situation, which is in a flash when being applied second strength F2
Strength or excessive strength suddenly), be similar to above-mentioned second of situation, which responds second couple of amount of stress F2 '
It at least can partially or fully close the channel 50 of the piston 24 and cushion effect is enabled to increase, and the elastic component 32 accumulates elastic force F3.
As shown in Figure 10, Figure 11 and Figure 12, once it is applied in the speed of the piston 24 or second strength F2 of the extension 26
State cushion effect increase and drop it is slow to a certain extent when or second strength F2 drop to less than what the elastic component 32 was accumulated
When elastic force F3, which then discharges elastic force F3 and is applied to the control piece 30, and the control piece 30 is made to leave the pre-determined bit
X is set without the channel 50 of the re-closed piston 24.It follows that the buffer unit 20 because should the third situation can be from second
It is relatively weak that kind buffer function is converted into cushion effect.Also that is, the buffer unit 20 has variable buffer function.

There is a height difference H between contact portion 310.Furthermore, pedestal 314 is connected to the company of the piston 304 by extension 316
Socket part 308.On the other hand, control piece 318 and elastic component 302 can be along the extension 316 and in the channels of the pedestal 314 320
It is movable between the channel 322 of the piston 304.When extension 324 or piston 304 receive strength F5 (or an external force), pre-
Determine in buffer situation, what which responded the fluid of buffer object can be against to the piston 304 to amount of stress K
Contact portion 310 and partially or fully close the channel 322 of the piston 304, pass through the piston 304 to control the buffer object
Channel 322 flow, to enable cushion effect increase, and the elastic component 302 is resisted against the surface of the interconnecting piece 308 of the piston 304
It 312 and is resiliently deformed by the height difference H, to accumulate an elastic force.Wherein, when strength F5 decrease, the elastic component 302
After discharging the elastic force, the channel 322 of the control piece 318 just not re-closed piston 304.
As Figure 17 and Figure 18 shows the buffer unit 400 of fourth embodiment of the invention.Specifically, this fourth embodiment
Buffer unit 400 and the difference of the buffer unit 20,200,300 of the first, second and third embodiment are substantially: control piece 402 and bullet

P3 (e.g. open position) (as shown in figure 24) is set, this self i.e. so-called open function.Wherein, when second piece of furniture 62
With respect to first piece of furniture 60 from the third place P3 toward first direction D1 by user be pushed into and be moved to close to this first
In the latter end stroke of position P1, includes that a closing spring provides a closing forces by the folding mechanism 66, make second piece of furniture
62 can be displaced towards first position P1, this self i.e. so-called closure function.Wherein, it is closed due to self open function with self
Close function be familiar with the field usual skill it will be appreciated that technology scope do not repeated separately in this for brevity.Separately
On the one hand, by the relative disPlacement motion of piston 24 (or extension 26) and shell 22 of the buffer unit 20, it is capable of providing this
Second piece of furniture 62, which is responded during the closing forces are displaced towards first position P1, has buffer function.
As Figure 25 shows the curve graph of the cushion effect of the first aforementioned situation, wherein ordinate is that newton is indicated with N, horizontal
Coordinate is that distance is indicated with mm.
For example, when second piece of furniture 62 is led to from the third place P3 toward first direction D1 towards during first position P1 displacement
When crossing the buffer unit 20 offer cushion effect, according to the first above-mentioned situation (this part can refer to shown in Fig. 7 and Fig. 8), buffering
The fluid of medium can be flowed out from the passway E1 in the channel of the pedestal 28 48, then reach the work by the channel 50 of the piston 24
The region of first side 24a of plug 24, therefore, (such as above-mentioned buffering is pre- from the buffering dark zone B1 before the P1 of first position by cushion effect D
Standby state) reach a host buffer region B2 during, cushion effect D can in response to be continuously applied in second piece of furniture 62 first
Strength (the e.g. closing forces of folding mechanism 66) and maintain substantially to level off to consistent size, that is to say, that buffering dress
The first buffer function can be generated before second piece of furniture 62 reaches first position P1 by setting 20, to slow down second piece of furniture
62 reach the speed before the P1 of first position.In addition, defining an overpressured zone B3 between first position P1 and second position P2.This
When, because the channel 50 of the control piece 30 is towards the channel of the piston 24 50 unclosed piston 24 permits as shown in Fig. 5 to Fig. 8
Perhaps second piece of furniture 62 is moved to second position P2 from first position P1 with respect to first piece of furniture 60.

When crossing the buffer unit 20 offer cushion effect, according to above-mentioned second of situation (this part can refer to shown in Fig. 9 and Figure 10), the control
Product 30 can partially or fully close the channel 50 of the piston 24, to control the second side of the buffer object from the piston 24
The region of 24b reaches the flow in the region of the first side 24a by the channel 50 of the piston 24.Therefore, as shown in figure 26, buffer
During power D reaches host buffer region B2 from the buffering dark zone B1 before the P1 of the closed position, cushion effect D can be in response to applying
It is added in the second strength of second piece of furniture 62 (e.g. user is continuously applied excessive strength to second piece of furniture 62)
And significantly rise, that is to say, that the buffer unit 20 can generate the before second piece of furniture 62 reaches first position P1
Two kinds of buffer functions, rapidly to slow down the velocity of displacement of second piece of furniture 62.At this point, because the control piece closes the piston
When channel, second piece of furniture can substantially be prevented to be moved to the second position from the first position with respect to first piece of furniture,
Deliberated with preventing the second piece of furniture 62 (drawer 62a) to be moved to second position P2 with respect to the first piece of furniture 60 (cabinet body 60a)
Ground (non-original idea) device for ejecting 64 offer opening force is provided.
Alternatively, when second piece of furniture 62 is led to from the third place P3 toward first direction D1 towards during first position P1 displacement
When crossing the buffer unit 20 offer cushion effect, according to the third above-mentioned situation (this part can refer to shown in Fig. 9 to Figure 12), the control
Product 30 can partially or fully close the channel 50 of the piston 24, to control the second side of the buffer object from the piston 24
The region of 24b reaches the flow in the region of the first side 24a by the channel 50 of the piston 24；In addition, be once applied to this
Two piece of furniture, 62 second strength (e.g. user applies moment excessive strength to second piece of furniture 62) delays one by drop
When determining degree, which then discharges the elastic force and is applied to the control piece 30, make the control piece 30 leave predetermined position X and
Therefore the channel 50 of the not re-closed piston 24 makes second of buffer function be converted into the third weaker degree of cushion effect
Buffer function.Therefore, as shown in figure 27, cushion effect D reaches the main buffering region from the buffering dark zone B1 before the P1 of first position
During the B2 of domain, cushion effect D can significantly rise in response to the second strength for being applied to second piece of furniture 62, and this
Before two piece of furniture 62 reach first position P1, cushion effect D is rapidly weakened.
It follows that the buffer unit 20 can provide different degrees of buffer function in response to different external force.Wherein,
When second piece of furniture 62 is applied by user toward first direction D1's with respect to first piece of furniture 60 from the third place P3
Be momentarily pushed into strength it is excessive when, provide above-mentioned second or the buffer function of the third degree by the buffer unit 20, can
