Description
Technical field
Delay with magnetic converting technique field, one kind movement of more particularly to use MR damper the present invention relates to manufacture
Chongmen.
Background technology
In daily life, in family or the mobile door major part of office is manufactured with aluminum alloy material, when right
When movement door promote opening or close, because the effect of inertia of mobile door can occur rigid collision and produce to make an uproar with doorframe
Sound.Except long-term rigid collision can cause certain damage to mobile door and doorframe, colliding the noise for producing equally can also beat
Other people normal work or rest is disturbed, certain trouble is caused.Magnetic rheological liquid damper has good damping effect, often quilt
The vibration damping of vibration damping and road and bridge for automotive suspension, effect is also clearly.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of mobile cushioning door based on magnetic rheology effect, and the device is to adopt
With the magnetic rheology effect of magnetic flow liquid, using MR damper device, can realize ensuring that moving door is gently automatically switched off, it is soft
With noiseless, generation noise when effectively solving the problems, such as mobile door because of inertial impaction doorframe and clashing into.
In order to effectively solve to move the deficiency as described above of door, the present invention is realized as follows：It is a kind of
Mobile cushioning door based on magnetic rheology effect, including doorframe 1, mobile door 2, block 301, block 302, MR damper 401,
MR damper 402, wherein MR damper 401 and MR damper 402 be specification damper of the same race, by nut 5,
Spring 6, housing 7, piston 8, bearing 9, piston rod 10, coil 11, magnetic flow liquid 12 are constituted, and wherein block 301 and block 302 is
Specification block of the same race；The inside of described MR damper 401 (or 402) is provided with piston rod 10, is equipped with piston rod 10
Coil 11 is provided with piston 8, piston 8, the overall right-hand member of piston 8 is fixed by the shaft shoulder of piston rod 10, and left end is solid by nut 5
Fixed, the left end of piston rod 10 connects housing 7 by spring 6；Described MR damper 401 is arranged on the left upper end of doorframe 1,
MR damper 402 is arranged on the upper right side of doorframe 1；Described block 301,302 is arranged on the top of mobile door 2.Work as shifting
Dynamic door 2 is moved to the left, and when block 301 just starts to contact the piston rod 10 of MR damper 401, coil 11 is passed through certain electricity
Stream, the magnetic flow liquid 12 of MR damper 401 is changed into Bingham fluid, there is larger viscosity, can produce from original Newtonian fluid
The certain shearing force of life, mobile door 2 reduces speed now, and when piston rod 10 just reaches range, mobile door 2 is moved to just
At doorframe 1, it is to avoid the shock of mobile door 2 and doorframe 1 and the noise produced when clashing into, realize that mobile door 2 is gently automatic to close
Close, soft noiseless effect, it is also such similarly to move door 2 and move right.
It is of the present invention it is a kind of based on magnetic rheology effect mobile cushioning door good effect be：Using magnetic flow liquid
Magnetic rheology effect, using MR damper device, can realize ensuring that moving door is gently automatically switched off, it is soft noiseless, have
Generation noise when solving the problems, such as mobile door because of inertial impaction doorframe and clashing into of effect.
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is outside drawing of the present invention.
Fig. 2 is the structural representation of MR damper of the invention.
1. doorframe in figure, 2. moves door, 301. blocks, 302. blocks, 401. MR dampers, 402. magnetorheological dampings

Specific embodiment
In Fig. 1, a kind of mobile cushioning door based on magnetic rheology effect of the present invention is by doorframe 1, mobile door 2, block
301st, block 302, MR damper 401, MR damper 402 are constituted.Mobile door 2, mobile door 2 are installed on doorframe 1
Upper end be equipped with block 301 and 302, doorframe 1 left upper end be equipped with MR damper 401, upper right side be equipped with magnetic current variable resistance
Buddhist nun's device 402.
In fig. 2, a kind of damper 401 (or 402) of the mobile cushioning door based on magnetic rheology effect of the present invention is by spiral shell
Female 5, spring 6, housing 7, piston 8, bearing 9, piston rod 10, coil 11, magnetic flow liquid 12 are constituted.Damper 401 (or 402)
Inside is provided with piston rod 10, is equipped with piston rod 10 and coil 11 is provided with piston 8, piston 8, and the overall right-hand member of piston 8 is relied on
The shaft shoulder of piston rod 10 is fixed, and left end is fixed by nut 5, and the left end of piston rod 10 connects housing 7 by spring 6.
A kind of operation principle of specific embodiment of the mobile cushioning door based on magnetic rheology effect of the present invention is：
When mobile door 2 is moved to the left, when block 301 just starts to contact the piston rod 10 of MR damper 401, coil 11
Certain electric current is passed through, the magnetic flow liquid 12 of MR damper 401 is changed into Bingham fluid, there is larger from original Newtonian fluid
Viscosity, certain shearing force can be produced, now move the shearing force and bullet of the inertia force of door 2 less than MR damper 401
The elastic force (shearing force and elastic force direction are while to the right) of spring 6, mobile door 2 reduces speed now.When piston rod 10 just reaches maximum row
Cheng Shi, mobile door 2 is moved at doorframe 1 just, it is to avoid the shock of mobile door 2 and doorframe 1 and the noise produced when clashing into, reality
Show mobile door 2 to be gently automatically switched off, soft noiseless effect now moves door 2 and remains static, but because spring 6 is
In compressive state, there is the trend for making piston rod 10 towards right motion, magnetic flow liquid 12 can produce shearing force to the left so that shearing
Power just balances elastic force, and mobile door 2 continues remains stationary state.When mobile door 2 moves right, it is only necessary to slowly reduce coil
11 electric currents being passed through, now the magnetic flow liquid 12 of MR damper 401 shearing force to the left is less than spring force to the right, shifting
Dynamic door 2 can slowly move right.When mobile door 2 moves right excessive velocities, similarly also can be by block 302 and MR damper
402 enter row buffering, realize mobile door 2 and are gently automatically switched off, soft noiseless effect.
