Description

TECHNICAL FIELD

[0001] The present application relates to the field of damping devices, in particular to a multi-channel friction composite magneto-rheological damper. BACKGROUND

[0002] The magneto-rheological fluid is a new type of intelligent material, which is a suspension prepared by mixing a liquid base and micron-sized metal particles in a container and stirring uniformly. The apparent viscosity of the magneto-rheological fluid changes significantly when the external magnetic field increases, and even becomes a solid, so that it is used as a force transmission medium; when the external magnetic field is removed, the magneto-rheological fluid returns to the original liquid state, and the response time is only a few milliseconds. Due to this chain arrangement structure, the rheological properties of the magneto-rheological fluid change from Newtonian fluid to solid-like state instantaneously, and the shear yield stress is significantly improved, and this change is continuous, controllable and reversible. The magneto-rheological damper made of this material not only has large output and small energy consumption, but also has the advantages of rapid response and good controllability, and is an ideal device for realizing semi-active control. However, the mechanism of the magneto-rheological effect has not been fully understood and accepted by people, and from the microscope, it can be observed that the particles of the magneto-rheological fluid are distributed randomly under zero magnetic field, but under the action of the magnetic field, they are regularly arranged in chain bundles. It has the characteristics of being a Newtonian fluid under zero magnetic field and a Bingham body under strong magnetic field.

[0003] The magneto-rheological fluid can be used to make a damper, and the flowability of the magneto-rheological fluid is controlled by the magnetic field strength, so that the movement resistance of the moving part of the damper in the magneto-rheological fluid changes, and the effect of energy absorption and vibration reduction is produced.

[0004] The existing magneto-rheological fluid damping device is a modification based on the traditional damper, and the liquid flow channel in the valve usually adopts a single-piston linear type, and the design of controlling the damping force by the size of the liquid flow channel is retained, which cannot efficiently utilize the characteristics of the magneto-rheological fluid, and the output damping force is limited, which limits the performance of the magneto-rheological fluid damper. Therefore, based on the characteristics of the magneto-rheological fluid, a multi-channel friction composite magneto-rheological damper with a composite multi-stage energy dissipation structure is proposed.

[0026] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details given herein, that the present application can be practiced with other than the described embodiments, and that the present application can be practiced with different or additional components, elements, acts, or steps. Thus, the present application is not limited to the embodiments described herein but is instead broad in scope.

[0028] Secondly, the "one embodiment" or "an embodiment" referred to herein means that a specific feature, structure, or characteristic described can be included in at least one implementation of the present application. The "in one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0029] Embodiment 1, with reference to Figure 1 and Figure 2 The first embodiment of the present application provides a multi-channel friction composite magneto-rheological damper, which can achieve high-performance damping effect in a short movement stroke, solves the problem that the traditional magneto-rheological damper cannot fully exert the performance of magneto-rheological fluid, resulting in low output damping force, and includes a bearing mechanism 100 including a damping plate 101 and a sealed cylinder 103, the damping plate 101 is provided with an adapter plate 102 at both ends, the damping plate 101 penetrates the sealed cylinder 103, and the damping plate 101 is distributed at equal intervals in the sealed cylinder 103; a damping mechanism 200 including magneto-rheological fluid located in the sealed cylinder 103, and a limiting block 201 arranged on both sides of the damping plate 101, the two ends of the limiting block 201 are fixedly connected with the inner wall of the sealed cylinder 103, and the damping plate 101 is fixedly sleeved with an electromagnetic assembly 202, the electromagnetic assembly 202 is distributed at the top end and the bottom end of the limiting block 201, and the electromagnetic assembly 202 is composed of a magnetically conductive half-shell 202a and a coil 202b.

[0030] Based on the existing operation mode of magnetorheological fluid dampers, the working principle of this multi-channel composite magnetorheological damper is further explained: Existing magnetorheological dampers are modified from traditional telescopic rod or telescopic barrel dampers. The method involves replacing the damping oil in the original damper with magnetorheological fluid and adding electromagnetic devices to the damper to control the flow rate of the magnetorheological fluid, thereby providing damping force for the piston movement within the damper. This type of damper still belongs to the valve-type damper category. However, to ensure the pressure-bearing capacity and sealing of the piston movement, this type of damper is generally a single-piston linear design, resulting in a relatively short effective damping channel length. Due to the limited channel length, the fluid cannot flow within a sufficient distance and is thus affected, leading to... The relatively small output damping force limits the efficiency and functionality of valve-type magnetorheological dampers in certain high-performance applications. Furthermore, the control range of existing built-in valve-type magnetorheological dampers is limited. One method to increase the output damping force is to change the fluid path and increase the strength of the internal magnetic field; however, this method has a limited control range and cannot meet the needs of some applications requiring a wide range of damping adjustments. Another method is to introduce a damping adjustment device, but some of these devices are large in size or stroke, which may impose limitations on installation and use. These limitations restrict the flexibility and adaptability of existing built-in valve-type magnetorheological dampers to some extent.

[0031] Returning to the multi-channel friction composite magnetorheological damper, although this device also provides damping force during structural expansion and contraction, it completely abandons the traditional piston structure. Instead, it achieves this through the deformation of a synthetic rubber damping plate 101. Its operation is as follows: when both ends of the damping plate 101 are compressed or impacted, the S-shaped bending length of the damping plate 101 shortens. Simultaneously, the protruding part of the S-shaped deformation contacts and rubs against the limiting block 201. This S-shaped deformation significantly increases the damping force along the axis of the multi-channel friction composite magnetorheological damper. The upward projected area further increases the resistance to movement of the damping plate 101 in the magnetorheological fluid. It is also known that as the damping plate 101 is further compressed, the S-shaped fold deformation increases, further increasing the resistance to movement and thus increasing the damping force output. This gives the device a certain degree of adaptability. Besides providing damping through the interaction between the elastic deformation of the damping plate 101, the magnetorheological fluid, and the limiting block 201, this multi-channel friction composite magnetorheological damper also incorporates a large number of electromagnetic components 202. Figure 4As can be seen, the damping plate 101 of the device has multiple layers, and each layer of the damping plate 101 is provided with a plurality of electromagnetic assemblies 202, which are composed of a half shell 202a fixedly sleeving the damping plate 101 and a coil 202b wound around the half shell 202a, wherein the half shell 202a made of silicon steel serves as an iron core for magnetic conduction and restricts the magnetic field in a smaller range to improve the magnetic field strength. In the process of contraction and deformation of the damping plate 101, the electromagnetic assemblies 202 also move and change the fluidity of the magnetorheological fluid in their vicinity through electromagnetic fields, thereby efficiently utilizing the magnetorheological fluid to provide motion damping. In summary, the multi-channel friction composite magnetorheological damper fully utilizes the magnetorheological fluid through multiple working modes to achieve efficient damping force output.

[0032] In summary, the device can achieve high-performance damping effect in a short motion stroke, effectively solving the problem that the traditional magnetorheological damper cannot fully utilize the performance of the magnetorheological fluid, resulting in low output damping force.

[0033] Embodiment 2, refer to Figures 1 to 3 The second embodiment of the present application is different from the previous embodiment in that it provides a bearing mechanism 100 of the multi-channel friction composite magnetorheological damper, which realizes the stable working conditions of the magnetorheological fluid inside the magnetorheological damper and the connection and support of the equipment outside, and is the foundation of the operation of the magnetorheological fluid damping mechanism 200. It solves the hardware condition requirement of efficient operation of the magnetorheological fluid damping mechanism 200, which includes the mutual perpendicularity between the damping plate 101 and the adapter plate 102, and the two steel plates 104 arranged at the two ends of the two adapter plates 102 away from each other. The adapter plate 102 is arranged in a rectangular shape, and the four corners of the adapter plate 102 are provided with first screws 106, and the rod portions of the first screws 106 are vertically penetrated through the steel plates 104.

[0034] Specifically, the top end and the bottom end of the sealing cylinder 103 are provided with annular grooves 103a, and the annular grooves 103a are coaxial with the sealing cylinder 103. The spring 107 is arranged between the sealing cylinder 103 and the adapter plate 102, one end of the spring 107 is sleeved with the annular groove 103a, the other end of the spring 107 is pressed against the adapter plate 102, and the damping plate 101 is sleeved in the spring 107. The spring 107 is used to assist the rebound of the damping plate 101, and also responsible for assisting the damping plate 101 to bear part of the impact force;

[0035] The two ends of the sealing cylinder 103 are provided with insertion grooves 103b, and a strip-shaped groove 103c is formed in the inner wall of the insertion groove 103b along one side thereof. The strip-shaped groove 103c is sealingly sleeved with a sealing ring 103d. The damping plate 101 is inserted into the insertion groove 103b, and the peripheral wall of the damping plate 101 is in extrusion contact with the sealing ring 103d. The sealing ring 103d designed at this position is hard, which is made by bending a stainless steel wire with a smooth surface and connecting the first end and the second end, and is embedded in the strip-shaped groove 103c. The sealing ring 103d has the effect of forming a protrusion on the inner wall of the insertion groove 103b to extrude the damping plate 101, thereby enhancing the good sealing between the damping plate 101 and the sealing cylinder 103.

[0036] A rectangular tube 108 is arranged in the sealing cylinder 103, and the two ends of the rectangular tube 108 are sealingly connected to the inner wall of the sealing cylinder 103. The rectangular tube 108 is distributed on both sides of the electromagnetic assembly 202. The two ends of the rectangular tube 108 are sealingly welded to the inner wall of the sealing cylinder 103. In addition to enhancing the structural strength of the sealing cylinder 103, the rectangular tube 108 also plays a role in filling the internal space of the sealing cylinder 103, thereby reducing the use amount of the magnetorheological fluid and saving costs.

[0037] It is to be noted that the device is characterized by the deformation of the damping plate 101 made of synthetic rubber. Therefore, the damping plate 101 will not only deform in the sealing cylinder 103, but also deform when the part exposed outside the sealing cylinder 103 is pressed. This will hinder the extension and contraction movement of the damping plate 101 relative to the sealing cylinder 103, and in severe cases, it will block the extension and contraction movement of the damping plate 101 relative to the sealing cylinder 103, causing extrusion damage. Therefore, the following structure is provided. The two ends of the sealing cylinder 103 are provided with guide rods 109 on both sides of the insertion grooves 103b, and the guide rods 109 are perpendicular to the sealing cylinder 103. The guide rods 109 are arranged in close contact with the damping plate 101, and the guide rods 109 penetrate the adapter plate 102 and the steel plate 104. The four corners of the steel plate 104 are provided with supporting feet 105, and the first screws 106 are fixedly connected to the supporting feet 105. The contact surface of the supporting feet 105 is provided with anti-skid lines. The supporting height of the supporting feet 105 is greater than the length of the guide rods 109. As shown in the attached drawings, the supporting feet 105 are arranged on the ground to support the device. Figure 2 and Figure 3 As can be seen, under the guidance of the guide rods 109, the part of the damping plate 101 between the guide rods 109 can only move in the axial direction of the multi-channel friction composite magnetorheological damper, and is prevented from being bent to the two sides, thereby ensuring smooth extension and contraction movement of the damping plate 101 relative to the sealing cylinder 103. The purpose of arranging the steel plate 104 is to uniformly apply pressure and impact force from the outside to the adapter plate 102 and the damping plate 101. The purpose of arranging the supporting feet 105 is to raise the space for the movement of the guide rods 109.

[0038] The remaining structures are the same as those of Example 1.

[0039] In summary, the device realizes that the magneto-rheological damper provides stable working conditions for the magneto-rheological fluid, and connects and supports the equipment, which is the basis for the operation of the damping mechanism 200 of the magneto-rheological fluid, and solves the hardware condition requirement of the high-efficiency operation of the magneto-rheological fluid damping mechanism 200.

[0040] Embodiment 3, refer to Figures 2 to 7 , the third embodiment of the present application, different from the previous embodiment, provides a damping mechanism 200 of a multi-channel friction composite magneto-rheological damper, which solves the problem of small output damping force of the traditional valve type magneto-rheological damper, which comprises an L-shaped clamping groove 202a-1 opened at both ends of a half shell 202a, a pair of half shells 202a and a damping plate 101 are sleeved, and the L-shaped clamping grooves 202a-1 at both ends of the half shell 202a are matched and connected, and the second screw 202c is connected through the superposition of the L-shaped clamping grooves 202a-1, and the coil 202b is uniformly connected with the outer wall of the half shell 202a.

[0041] The operating principle of the damping mechanism 200 is described in Embodiment 1, and the damping mechanism 200 is described in this embodiment.

[0042] As shown in the accompanying Figure 2 , Figure 4 and Figure 6 , the position distribution between the electromagnetic assembly 202, the limiting block 201 and the damping plate 101 can be seen. The limiting block 201 and the damping plate 101 maintain a certain distance, when the damping plate 101 is deformed under pressure, the deformed part contacts the limiting block 201 and generates extrusion friction to generate damping. Therefore, if the deformation of the damping plate 101 is not limited by the limiting block 201, the damping plate 101 will easily deform to the side and be easily compressed, and cannot effectively form support force and damping force output to the outside. By limiting the lateral deformation of the damping plate 101 by the limiting block 201, the friction force generated by the extrusion is used to provide damping, so that the greater the external pressure or impact force, the greater the extrusion force of the damping plate 101 on the limiting block 201 after deformation, and the higher the friction resistance formed, which makes the damping plate 101 have strong support force in the axial direction of the multi-channel friction composite magneto-rheological damper.

[0043] As shown in the enlarged part in Figure 6 and Figure 7 , a pair of matched half shells 202a are connected through the L-shaped clamping grooves 202a-1 at both ends, and are locked by the second screw 202c. The matched half shells 202a need to clamp the damping plate 101 to align the holes at both ends, so that the second screw 202c can be assembled smoothly, which helps to control the clamping force of each electromagnetic assembly 202 on the damping plate 101 not to be too high or too low.

[0044] The rest of the structure is the same as that of Example 2.

[0045] In summary, the device solves the problem of the small output damping force of the traditional valve type magneto-rheological damper.
