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 compositions, wherein the first block 301 and the second block 302 are specification block of the same race；Described the first MR damper 401 or
The inside of second MR damper 402 is provided with piston rod 10, and piston 8 is housed on piston rod 10, set in piston 8 wired
Circle 11,8 overall right-hand member of piston are fixed by the shaft shoulder of piston rod 10, and left end is fixed by nut 5, and the left end of piston rod 10 passes through
Spring 6 connects housing 7；The first described MR damper 401 is arranged on the left upper end of doorframe 1, the second MR damper
402 are arranged on the upper right side of doorframe 1；Described the first block 301, the second block 302 are arranged on the top of mobile door 2.Work as shifting
Dynamic door 2 is moved to the left, and when the first block 301 just starts to contact the piston rod 10 of the first MR damper 401, coil 11 is passed through
Certain electric current, the magnetic flow liquid 12 of the first MR damper 401 are changed into Bingham fluid from original Newtonian fluid, had larger
Viscosity, can produce certain shearing force, mobile door 2 reduces speed now, when piston rod 10 just reaches range, mobile door
2 are moved at doorframe 1 just, avoid mobile door 2 and noise caused by the shock and shock of doorframe 1, realize mobile door 2
Gently automatic to close, soft noiseless effect, it is also such similarly to move door 2 and move right.
A kind of good effect of mobile cushioning door based on magnetic rheology effect described in the utility model is：Using magnetic current
Become the magnetic rheology effect of liquid, using MR damper device, can realize ensures that move door gently closes automatically, soft nothing
Sound, it is effective to solve the problems, such as that mobile door produces noise because of inertial impaction doorframe and when hitting.

Embodiment
In Fig. 1, a kind of mobile cushioning door based on magnetic rheology effect of the utility model is by doorframe 1, mobile door 2, the
One block 301, the second block 302, the first MR damper 401, the second MR damper 402 form.Pacify on doorframe 1
The mobile door 2 of dress, the upper end of mobile door 2 are equipped with the first block 301 and the second block 302, first magnetic are housed in the left upper end of doorframe 1
Rheological damper 401, upper right side are equipped with the second MR damper 402.
In fig. 2, a kind of first MR damper 401 of the mobile cushioning door based on magnetic rheology effect of the utility model
Or second MR damper 402 be by nut 5, spring 6, housing 7, piston 8, bearing 9, piston rod 10, coil 11, magnetorheological
Liquid 12 forms.The inside of first MR damper 401 or the second MR damper 402 is provided with piston rod 10, piston rod
Piston 8 is housed on 10, is provided with coil 11 in piston 8,8 overall right-hand member of piston is fixed by the shaft shoulder of piston rod 10, left end according to
Fixed by nut 5, the left end of piston rod 10 connects housing 7 by spring 6；The first described MR damper 401 is arranged on
The left upper end of doorframe 1, the second MR damper 402 are arranged on the upper right side of doorframe 1；The first described block 301, second
Block 302 is arranged on the top of mobile door 2.
A kind of operation principle of the embodiment of the mobile cushioning door based on magnetic rheology effect of the utility model is：
When mobile door 2 is moved to the left, the first block 301 just starts to contact the piston rod 10 of the first MR damper 401
When, coil 11 is passed through certain electric current, and the magnetic flow liquid 12 of the first MR damper 401 is changed into guest from original Newtonian fluid
Chinese fluid, there is larger viscosity, certain shearing force can be produced, the inertia force for now moving door 2 is less than the first magnetorheological damping
The elastic force of the shearing force of device 401 and spring 6 (shearing force and elastic force direction simultaneously to the right), mobile door 2 reduces speed now.Work as piston rod
10 when just reaching range, and mobile door 2 is moved at doorframe 1 just, is avoided the shock of mobile door 2 and doorframe 1 and is hit
Caused noise is hit, the gently automatic closing of mobile door 2 is realized, soft noiseless effect, now moves door 2 and be in static shape
State, but because spring 6 is to be in compressive state, have the trend for making piston rod 10 towards right motion, magnetic flow liquid 12 can produce to the left
Shearing force so that shearing force just balances elastic force, and mobile door 2 continues remains stationary state.When mobile door 2 moves right,
Only need slowly to reduce the electric current that coil 11 is passed through, now the shearing of the magnetic flow liquid 12 of the first MR damper 401 to the left
Power is less than spring force to the right, and mobile door 2 can slowly move right.When mobile door 2 moves right excessive velocities, similarly also can
Row buffering is entered by the second block 302 and the second MR damper 402, realizes the gently automatic closing of mobile door 2, soft nothing
The effect of sound.
