The carbonyl iron particles provide a means by which the fluid can be changed to a solid state, and the change in the magnetic field is forced to force the carbonyl iron particles in the magnetorheological fluid to change the arrangement, resulting in the magnetorheological fluid temporarily becoming solid from the liquid. When the magnetic field M378853 is removed, the rebel iron particles are unlocked and the magnetorheological fluid changes back from solid to liquid. Magnetorheological fluids are commonly used in washing machines, car shock absorbers, and artificial legs...etc. Magnetic fluids have been around since the 1940s.

The nitrogen gas a in the second chamber 32a of the 5H is described, and the gas pressure of the nitrogen gas a is used to buffer the force of the floating piston 27a when the piston rod 15a is pressed down. The piston rod 15a is provided with a piston 2ia at the bottom end thereof. The piston 2ia is composed of a nut 211a, a cylinder 221a, a first disc body 212a, a plurality of spring pieces 219a and 220a, a conductive coil unit 214a, and a first The second disk body 213a is configured; the first disk body 212a, the plurality of spring pieces 219a, 22A, the conductive coil unit 214a, and the second disk body 213a are disposed around the column 221a; the first disk body 212a, the second disk body 231a and the conductive coil unit 214a are clamped and fixed therein by the number of spring pieces M378853 219a, 220a. The first disk body 212a and the second body 213a are respectively provided with gaskets 215a and 216a to be tightly sleeved with the inner wall of the outer tube 22a. The first disk body 212a and the second disk body 213a are respectively disposed on both sides. The openings 2i7a, 21 are known. The fifth conductive coil unit 214a includes a coil ring 2141a and a plurality of conductive coils 2142a. The conductive coil 2142a is disposed around the coil ring 2141a. The outer diameter of the conductive coil unit 2i4a is slightly smaller than the inner diameter of the outer cylinder 22a. To form a predetermined gap s; the coil ring 2141a is provided with an opening 2143a at a predetermined position to communicate with an opening (not shown) of the cylinder 221a for the wire of the conductive coil 2142a to pass through; The wire of the conductive coil 2142a is passed through the inside of the piston rod 15a (not shown) to the bottom end of the connecting portion 17a to connect an external power source. When the other embodiment of the present invention is actually applied, when the connecting portion 17a is down to the downward pressure, the piston rod 15a will move relatively downward in the working cylinder 1 ia, at this time, the first chamber 31a The magnetorheological fluid L in the upper portion flows upward from the opening 2i7a of the first disk body 2i2a with respect to the piston rod 15a, and passes through the gap S' between the conductive coil unit 214a and the inner wall of the outer tube 22a. The opening 218a on the two sides of the two disc bodies 213a flows upward. At this time, if the conductive coil 2142a is input by current, according to the principle of electromagnetic induction, a magnetic force is generated around the conductive coil 2142a, and the magnetic force shears the opening 217a flowing through the two sides of the first disk 212a. The magnetorheological fluid L' in the opening 218a on the two sides of the two disc bodies 213a causes the magnetorheological fluid L to solidify;
12 [S M378853 此時因為該二開孔217a、218a内之磁流變液L產生固化， 故該第一容室31a内之磁流變液L會產生堵塞現象(產生阻 尼力）’此時該活塞桿15a往下運動所需之力量會增加。 而當輸入該導電線圈2142a之電流愈大，則該導電線 圈2142a所產生之磁力會相對愈強，流經該第一盤體212a 二側之開孔217a、該第二盤體213a之二侧之開孔218a中 的該磁流變液L固化會愈顯著；此時該活塞桿i5a往下運 動所需之力量會愈大。故可以調整輸入該導電線圈2i42a 之電流大小來改變該磁流變液避震器l〇a之阻尼力。 綜合以上所述’本創作可依照調整外部電流改變内部 導電線圈單元之磁力，進而改變磁流變液避震器内部磁流 變液之黏性，達到可調整磁流變液避震器之阻尼力，另使 用者於不同需求上可隨意調整阻尼力之避震器，已將磁流 變液避震器具體並以最佳化實施。 以上為本案所舉之實施例，僅為便於說明而設，當不 能以此限制本案之意義，即大凡依賴申請專利範圍所為 之各種變換設計，均應包含在本案之專利範圍中。 【圖式簡單說明】 第一圖係本創作磁流變液避震器之外觀圖。 第二圖係本創作磁流變液避震器之剖視圖。 第三圖係本創作磁流變液避震器之使用狀態剖視 圖012 [S M378853 At this time, since the magnetorheological fluid L in the two openings 217a and 218a is solidified, the magnetorheological fluid L in the first chamber 31a is clogged (generating damping force). The force required to move the piston rod 15a downward is increased. When the current of the conductive coil 2142a is increased, the magnetic force generated by the conductive coil 2142a is relatively strong, and the two sides of the opening 217a and the second disk 213a of the first disk 212a pass through the opening. The magnetorheological fluid L in the opening 218a will be more solidified; at this time, the force required for the piston rod i5a to move downward will be greater. Therefore, the magnitude of the current input to the conductive coil 2i42a can be adjusted to change the damping force of the magnetorheological fluid shock absorber l〇a. In summary, the above description can change the magnetic force of the internal conductive coil unit according to the adjustment of the external current, thereby changing the viscosity of the magneto-rheological fluid inside the magnetorheological fluid shock absorber, and achieving the damping of the adjustable magnetorheological fluid shock absorber. Force, another user can adjust the damping force of the shock absorbers on different needs, the magnetorheological fluid shock absorber has been specifically and optimized. The above embodiments of the present invention are provided for convenience of explanation. When the meaning of the case cannot be limited, that is, various transformation designs that rely on the scope of the patent application should be included in the patent scope of the present application.
