However, according to research, the magnetic flux density of the magnetorheological fluid gradually tends to magnetic saturation along with the increase of the magnetic field intensity, and the flow damping of the magnetorheological fluid does not change when the magnetic field intensity is continuously increased after the magnetorheological fluid is in a magnetic saturation state of the magnetic flux density. And the saturated magnetic flux density of the magneto-rheological damper is improved, so that the damping change range of the magneto-rheological damper can be enlarged, but the improvement of the saturated magnetic flux density of the magneto-rheological damper can be accompanied with the adverse effects of the increase of the self flow damping and the jamming of the primary action of the magneto-rheological damper. Therefore, the saturated magnetic flux density of the magnetorheological fluid is generally lower, which is also the reason that the damping regulation and control range of the existing magnetorheological shock absorber is narrow.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The magnitude of the damping force of the magnetorheological damper is related to the magnitude of the damping of the magnetorheological fluid, and the magnitude of the damping of the magnetorheological fluid is related to the magnetic flux density. However, according to research, it is shown that when the magnetic flux density of the magnetorheological fluid tends to be saturated magnetically, the magnetic strength continues to be increased and the flow damping of the magnetorheological fluid does not change. This also results in a limited range of variation of the damping of the magnetorheological shock absorber by increasing the saturation magnetic flux density of the magnetorheological fluid, and also in the problems of initial jamming of the magnetorheological shock absorber and a narrow range of adjustment and control of the damping. In view of the above problems, the present application provides an electromagnetic coil sheath for improving the problem of narrow damping adjustment range of a magnetorheological shock absorber, which is described below by embodiments.
The coil assembly comprises an inner magnetizer, an electromagnetic coil wound on the inner magnetizer, an outer magnetizer coaxially sleeved outside the inner magnetizer and arranged at intervals with the inner magnetizer, and an electromagnetic coil sheath sleeved outside the electromagnetic coil, wherein the magnetorheological fluid circulates among the outer magnetizer, the inner magnetizer and the electromagnetic coil sheath, and a magnetic induction line of a magnetic field generated after the electromagnetic coil is electrified flows between the inner magnetizer and the outer magnetizer through the magnetorheological fluid. Here, the magnetic flux density of the magnetorheological fluid is the number of the magnetic induction lines flowing through the cross-sectional areas of the inner magnetizer and the outer magnetizer, and the larger the cross-sectional areas of the inner magnetizer and the outer magnetizer are, the smaller the magnetic flux density of the magnetorheological fluid is, and vice versa.
Referring to fig. 2 and 4, the present application provides a solenoid sheath 100 for covering the outside of the solenoid of the coil assembly and located between the inner magnetizers. Specifically, the electromagnetic coil sheath 100 includes a diamagnetic body 10, and a first magnetic conductive part 20 and a second magnetic conductive part 30 respectively provided at opposite end sides of the diamagnetic body 10, where the diamagnetic body 10, the first magnetic conductive part 20, and the second magnetic conductive part 30 are all hollow structures. The first magnetic conduction part 20 and the second magnetic conduction part 30 are respectively abutted against the corresponding inner magnetizers. Here, the magnetism-conductive performance of the diamagnetic body 10 is weak or has no magnetism-conductive capability, while the magnetism-conductive performance of the first magnetism-conductive part 20 and the second magnetism-conductive part 30 is stronger and can be the same as or similar to the magnetism-conductive performance of the inner magnetizer. It can be understood that, when the first magnetic conduction portion 20 abuts against one end of the corresponding inner magnetic conductor and the second magnetic conduction portion 30 abuts against the other end of the corresponding inner magnetic conductor, the cross-sectional area of the inner magnetic conductor in the axial direction is increased, that is, the flowing area of the magnetic induction line between the inner magnetic conductor and the outer magnetic conductor is increased, so that the magnetic flux density of the magnetorheological fluid is reduced, and a basis is provided for subsequently changing the damping size range of the magnetorheological fluid only by increasing the magnetic field intensity.
The electromagnetic coil sheath 100 includes a diamagnetic body 10, and a first magnetic conductive part 20 and a second magnetic conductive part 30 respectively provided at opposite ends of the diamagnetic body 10. The first magnetic conduction part 20, the diamagnetic main body 10 and the second magnetic conduction part 30 which are sequentially connected form an annular channel with the outer magnetizer and the inner magnetizer of the coil assembly, in the cross section direction, the sectional areas of the inner magnetizer and the outer magnetizer are extended by the first magnetic conduction part 20 and the second magnetic conduction part 30, namely, the unit area is increased, the magnetic flux density of the magnetorheological fluid is reduced, and after the magnetic flux density of the magnetorheological fluid is reduced, the damping adjusting range of the magnetorheological damper can be improved by continuously improving the magnetic field intensity of the electromagnetic coil. And, compared to the way of increasing the length of the inner magnetizer and the outer magnetizer in the axial direction to reduce the magnetic flux density, the electromagnetic coil sheath 100 of the present application can further reduce the size of the coil assembly, and satisfy the requirements of small weight, low cost and being more suitable for magnetorheological dampers of different specifications.
Referring to fig. 2, in one embodiment, the length of the first magnetic conductive portion 20 is the same as the length of the second magnetic conductive portion 30. It can be understood that, when the first and second magnetic conductive parts 20 and 30 have the same length in the axial direction, that is, the magnetic conductive parts are symmetrically formed at the two opposite ends of the diamagnetic body 10, so that the magnetic conductive parts of the inner magnetic conductor of the coil assembly in the axial direction have the same length, form symmetrically closed magnetic flux lines, and also extend inwards in the axial direction by the same length to reduce the magnetic flux density of the magnetorheological fluid.
Referring to fig. 3, in another embodiment, the length of the first magnetic conductive portion 20 is different from the length of the second magnetic conductive portion 30. It can be understood that, in a specific application scenario, the lengths of the first magnetic conductive part 20 and the second magnetic conductive part 30 in the axial direction may also be unequal, that is, there is a difference between the lengths of the two, so that the magnetic conductive portions of the inner magnetic conductor of the coil assembly in the axial direction are extended by different lengths, thereby forming asymmetric closed magnetic flux lines.
In one embodiment, the diamagnetic body 10 is any one of a corrosion-resistant metal, diamond, and graphite. Here, the corrosion-resistant metal is a metal of gold, silver, or copper. Of course, other materials having weak magnetism may be used in addition to the above materials. The material of the diamagnetic body 10 is not limited here.
In one embodiment, the first magnetically permeable portion 20 is any one of pure iron, stainless steel and mild steel, and/or the second magnetically permeable portion 30 is any one of pure iron, stainless steel and mild steel. It will be appreciated that the first and second magnetically permeable portions 20, 30 have a strong magnetic property that is the same as or comparable to the magnetic property of the inner magnetic conductor, such that the magnetic flux lines of the magnetic field formed by the electromagnetic coil flow through the inner magnetic conductor, the magnetically permeable portions, and the outer magnetic conductor in sequence to form a closed loop. The material of the diamagnetic body 10 is not limited here.
In one embodiment, one end side of the diamagnetic body 10 is welded or adhesively connected to the first magnetic permeable part 20, and/or the other end side of the diamagnetic body 10 is welded or adhesively connected to the second magnetic permeable part 30. It is understood that, when the diamagnetic body 10, the first magnetic conductive part 20 and the second magnetic conductive part 30 are made of metal, they can be connected by welding. If the main body, the first magnetic conductive part 20 and the second magnetic conductive part 30 are made of different materials and are not suitable for welding, the main body, the first magnetic conductive part and the second magnetic conductive part are bonded by using a glue.
In one embodiment, one end of the diamagnetic body 10 is detachably connected to the first magnetically permeable part 20. It will be appreciated that, in order to further improve the adaptability of the electromagnetic coil, the length of the electromagnetic coil in the axial direction can be adjusted, and then the first magnetic conduction part 20 can be detachably connected to the diamagnetic body 10, for example, by a connection manner such as a screw connection, a snap connection, and a plug connection.
In one embodiment, the other end of the diamagnetic body 10 is detachably connected to the second magnetic conductive part 30. Similarly, in order to further improve the adaptability of the electromagnetic coil, the length of the electromagnetic coil in the axial direction can be adjusted, and then the second magnetic conduction part 30 can be detachably connected to the diamagnetic body 10, for example, by a connection method such as a screw connection, a snap connection, and a plug connection.
Of course, in another embodiment, the opposing ends of the diamagnetic body 10 are detachably connected to the first and second magnetically permeable parts 20 and 30, respectively, so that the magnetically permeable parts are replaced at the same time, and the first and second magnetically permeable parts 20 and 30 with moderate lengths can be selected.
In a second aspect, referring to fig. 4, the present application provides a coil assembly 200, which includes an inner magnetizer 201, an electromagnetic coil 203 wound around the inner magnetizer 201, and an outer magnetizer 204 coaxially sleeved outside the inner magnetizer 201 and spaced apart from the inner magnetizer 201, and further includes the above-mentioned electromagnetic coil 203 sheath 100, wherein the electromagnetic coil 203 sheath 100 is sleeved outside the electromagnetic coil 203 and located between the inner magnetizers 201.
The coil assembly 200 provided by the invention has the capability of reducing the magnetic flux density of the magnetorheological fluid on the basis of the electromagnetic coil 203 sheath 100, so that the damping regulation range of the magnetorheological damper is improved.
In a third aspect, the present application provides a magnetorheological damper including the coil assembly 200 described above.
The magneto-rheological shock absorber provided by the invention can improve the damping regulation range on the basis of the coil assembly 200.
