Description
Technical Field
The invention relates to the technical field of electrorheological valves, in particular to an electrorheological valve with a mesh electrode structure and a braille convex point linkage structure.
Background
The electrorheological valve is made by using the property that electrorheological fluid can reversibly convert from liquid state to similar solid state under the control of an external electric field. The working principle is as follows: when no external electric field control (zero field) exists, the electrorheological fluid transfers hydraulic pressure in a fluid state; when a control electric field is applied to the electrorheological fluid (working), the electrorheological fluid is converted into a solid-like state, a certain yield stress is presented, the yield stress is in positive correlation with the field intensity of an applied external electric field, when the field intensity of the external electric field exceeds a certain threshold value, the electrorheological valve consisting of the control electrode and the electrorheological fluid therebetween presents a certain valve pressure drop, the hydraulic pressure less than the valve pressure drop can be blocked, and the fluid state at the other end of the valve is not interfered.
The existing electrorheological valve is most often in a parallel plate capacitive structure, i.e. two electrodes are parallel to each other, and electrorheological fluid flows between the two electrodes. The zero field flow resistance of the valve is tightly coupled with the electrode gap, the valve gap needs to be increased when the flow resistance is reduced, and if the working electric field intensity of the electrorheological valve is kept and the pressure drop of the valve is not reduced, the electrode gap is increased and the external voltage of a control electric field needs to be improved, namely, the zero field flow resistance is tightly coupled with the external voltage. However, when the applied voltage is increased, the voltage-withstanding grade of the switching device for controlling the presence or absence of the applied voltage is also correspondingly increased, thereby bringing about double increases of the electric control cost and the volume, which is not favorable for product popularization and miniaturization.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defect that the existing electrorheological fluid valve cannot decouple the zero-field flow resistance and the applied voltage, so that the electric control cost and the volume are increased doubly, thereby providing the electrorheological valve with the mesh electrode structure, which can decouple the applied voltage and the zero-field flow resistance of the electrorheological valve.
In order to solve the above technical problem, the present invention provides an electrorheological valve with a mesh electrode structure, comprising:
the insulating gaskets are parallel to each other, gaps are reserved between every two adjacent insulating gaskets, through holes are formed in the middle of each insulating gasket, and all the through holes are distributed in an aligned mode so as to be suitable for forming a flow channel;
at least one positive metal mesh located in the gap and parallel to the insulating spacer;
at least one negative metal mesh positioned in the gap and parallel to the insulating spacer;
each gap is only used for accommodating one positive metal net or one negative metal net, all the positive metal nets and all the negative metal nets are alternately distributed along the direction of the flow passage, the positive metal nets and the negative metal nets both cover the through holes, and the areas around the through holes are both connected with the insulating gaskets in a sealing mode.
Optionally, all the positive electrode metal meshes extend out of the same side of the insulating spacer, and all the negative electrode metal meshes extend out of the opposite side of the insulating spacer.
Optionally, an end of the positive electrode metal mesh opposite to the overhanging side is placed in the gap, and an end of the negative electrode metal mesh opposite to the overhanging side is placed in the gap.
Optionally, a distance between an end of the positive electrode metal mesh placed in the gap and an edge of the insulating spacer corresponding to the outward side of the negative electrode metal mesh is greater than a thickness of the insulating spacer.
Optionally, the thickness of all the insulating spacers is the same.
Optionally, the positive electrode metal mesh region or the negative electrode metal mesh region around the through hole is connected with the insulating gasket in a sealing manner through glue.

and the at least two positioning columns vertically penetrate through all the insulating gaskets.
Optionally, the positioning column is a bolt, and a bolt is screwed at each corner of the insulating gasket.
The invention also provides a braille bump linkage structure, which comprises:
the electrorheological valve with the mesh electrode structure;
the salient point is positioned at the top of the flow channel;
and the power mechanism is communicated with the flow channel and is suitable for conveying or extracting the electrorheological fluid into the flow channel.
The technical scheme of the invention has the following advantages:
1. the invention provides an electrorheological valve with a reticular electrode structure, wherein electrodes are made of metal nets, and the metal nets are separated by insulating gaskets and are arranged in a laminated manner. On one hand, the formed control electric field is in non-uniform electric field distribution, and the electrode gap is mainly controlled by the thickness of the insulating spacer, the staggering between two adjacent copper nets and the rotating angle, so that the external voltage is controlled; on the other hand, the flowing direction of the electrorheological fluid is not only perpendicular to the direction of the electric field, so that the cross section of the flow channel is not only influenced by the electrode gap, but also mainly controlled by the density degree of the metal grids, thereby controlling the zero-field flowing resistance. Therefore, decoupling between the zero-field flow resistance and the external voltage is realized, so that the control parameters of the flow channel gap and the control parameters of the electrode gap are not strongly correlated, and the flow channel gap and the electrode gap can be independently controlled, thereby improving the regulation and control performance of the valve, and providing new possibility for further reducing the product cost and the product volume.
2. The electrorheological valve with the mesh electrode structure provided by the invention can be cut by the electrode metal wire in the flowing process of the electrorheological fluid, so that the aggregation state of the electrorheological fluid under an electric field can be damaged, and the distribution of particle phases in the electrorheological fluid can be improved; provides the opportunity of stirring and mixing the electrorheological fluid particle phase, increases the stability of the electrorheological fluid system, and is beneficial to delaying the sedimentation of the electrorheological fluid.
3. According to the electrorheological valve with the mesh electrode structure, the nonuniform electric field can increase the electric field intensity locally by utilizing the shrinkage of the mesh electrode in size, and the possibility of generating local high electric field intensity by adopting low external voltage is provided.
4. The electrorheological valve with the mesh electrode structure provided by the invention has the advantages that the electrode gap is controlled by the thickness of the insulating spacer, the density degree of the mesh electrode and the relative position (including the translation and relative rotation angle of the mesh) of the adjacent metal meshes, and the electric field can be configured by adopting the metal meshes with different densities.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Examples
Referring to fig. 1 to fig. 3, an electrorheological valve with a mesh electrode structure according to an embodiment of the present invention includes:
the insulating gaskets 1 are parallel to each other, gaps 11 are reserved between every two adjacent insulating gaskets 1, through holes 12 are formed in the middle of each insulating gasket 1, and all the through holes 12 are distributed in an aligned mode so as to be suitable for forming the flow channel 4; the insulating gasket 1 is provided with at least three to form at least two of the gaps; the shape of the insulating gasket 1 is not limited, and may be rectangular, circular, triangular or other common shapes, preferably the rectangular shape in fig. 2;
at least one positive metal mesh 2 located in the gap 11 and parallel to the insulating spacer 1; the material used for the positive electrode metal mesh 2 is not limited, and may be copper, aluminum, silver or the like, and preferably copper; the shape of the positive metal mesh 2 is not limited, and can be rectangular, circular, triangular or other common shapes, preferably the rectangular shape in fig. 2;
at least one negative metal mesh 3, which is positioned in the gap 11 and is parallel to the insulating gasket 1; the material used for the negative electrode metal mesh 3 is not limited, and may be copper, aluminum, silver or the like, and preferably copper; the shape of the negative electrode metal mesh 3 is not limited, and may be rectangular, circular, triangular or other common shapes, preferably the rectangular shape in fig. 2;
each gap 11 is only used for accommodating one positive metal net 2 or negative metal net 3, all the positive metal nets 2 and all the negative metal nets 3 are alternately distributed along the direction of the flow channel 4, the positive metal nets 2 and the negative metal nets 3 cover the through holes 12, the areas around the through holes 12 are hermetically connected with the insulating gasket 1, and all the through holes 12 are distributed in an aligned mode to form the flow channel 4; the mesh number of different metal nets can be designed to be different or the same, and the metal nets with different density can be adopted to configure the electric field during specific design, so that the adjustment parameters of the electric field are increased, and the design flexibility is improved.
The electrorheological valve of the embodiment is characterized in that metal nets are used for making a positive electrode and a negative electrode, the metal nets are perpendicular to the flow channel 4, a non-uniform electric field distribution is formed between the adjacent positive electrode metal net 2 and the adjacent negative electrode metal net 3, the electrode gap of the electrorheological valve is non-uniformly changed and is specifically controlled by the thickness of the insulating gasket 1 and the staggering and rotating angle between the adjacent metal nets, the flowing direction of electrorheological fluid is not only perpendicular to the direction of an electric field any more, and the zero field flow resistance of the electrorheological valve is mainly controlled by the density degree of the metal nets, so that the decoupling between the zero field flow resistance and the applied voltage is realized. Zero field flow resistance can be adjusted through adjusting the density degree of metal mesh, can cause the influence to the electrode gap when density changes, is that the electrode gap has been influenced promptly, because influence the electrode gap other factors such as 1 thickness of insulating pad in addition to these factors can not lead to the fact the influence to the flow resistance, so can adjust the electrode gap back to original value through adjusting this factor, guarantee that impressed voltage is unchangeable, so accomplish the decoupling zero.
Preferably, all the positive electrode metal meshes 2 extend out of the same side of the insulating spacer 1, and all the negative electrode metal meshes 3 extend out of the opposite side of the insulating spacer 1. The same positive electrode pressurizing equipment can be used for being connected with all the positive electrode metal nets 2, and the negative electrode is similar, so that compared with the condition that each metal net is connected with one pressurizing equipment, the structure cost is lower, and the control is more facilitated.
Preferably, an end of the positive electrode metal mesh 2 opposite to the overhanging side is placed in the gap 11, and an end of the negative electrode metal mesh 3 opposite to the overhanging side is placed in the gap 11. If the positive electrode metal mesh 2 and the negative electrode metal mesh 3 are extended outward on the same side of the insulating spacer 1, a creepage phenomenon is easily caused. Furthermore, the distance between the end part of the positive electrode metal net 2 arranged in the gap 11 and the edge of the insulating gasket 1 corresponding to the extending side of the negative electrode metal net 3 is larger than the thickness of the insulating gasket 1, so that creepage between electrodes with different polarities can be better avoided.
Preferably, all the insulating spacers 1 have the same thickness. Thus, the electrode arrangement is more uniform, and the connection of the electrode and external pressurizing equipment is facilitated. Of course, in other embodiments, the thickness of the insulating spacer 1 may be designed differently to meet the design of the electrode gap. It should be noted that, in designing, the insulating sheets at the uppermost layer and the lowermost layer do not need to control the electric field intensity, and the thickness can be determined according to the assembling requirement, but the thickness of the insulating spacer 1 between the mesh-shaped electrodes needs to be determined according to the required electric field intensity.
Preferably, the region of the positive metal mesh 2 or the region of the negative metal mesh 3 around the through hole 12 is in sealing connection with the insulating gasket 1 through glue. The glue can realize the sealing between the metal mesh and the insulating gasket 1 on one hand, and can also realize the fixation between the metal mesh and the insulating gasket on the other hand. Furthermore, the glue is AB glue, the AB glue is thick, the AB glue cannot flow into the flow channel 4 to seal the flow channel 4 during coating, and the operation is more convenient. Of course, in other embodiments, a sealing gasket fixed on the insulating gasket 1 may be used instead of the glue, or other ways of achieving sealing may be used.
As a modification, the electrorheological valve further comprises:
and the at least two positioning columns vertically penetrate through all the insulating gaskets 1. Before assembly, through holes 12 suitable for inserting the positioning columns are formed in the same positions of all the insulating gaskets 1, and during assembly, all the insulating gaskets 1 are only required to be inserted on the positioning columns in sequence, so that the consistency of the flow passages 4 can be guaranteed, and the operation is simplified. Furthermore, the positioning column is a bolt, and a bolt is screwed at each corner of the insulating gasket 1. The insulating gasket 1 is sleeved on the bolt to realize a positioning function, the consistency of the flow channel 4 is ensured, meanwhile, the bolt can be in threaded connection with other shell parts to compress the insulating gasket 1, and the sealing performance between the insulating gasket 1 and the metal net is ensured.
Referring to fig. 4, an embodiment of the present invention further provides a braille bump linkage structure, including:
the electrorheological valve with the mesh electrode structure;
the salient point 5 is positioned at the top of the flow channel 4;
and the power mechanism 6 is communicated with the flow channel 4 and is suitable for conveying or extracting the electrorheological fluid into the flow channel 4.
In order to better understand the scheme of the present application, the following linkage structure of the braille convex points in the prior art is introduced first: referring to fig. 5, the device comprises a braille convex point 5, an electrorheological fluid cavity 7, an electrorheological fluid flow channel 8, a control electrode 9 and a piston 10, wherein the control electrode 9 is provided with a positive electrode and a negative electrode which are arranged in parallel, electrorheological fluid only flows through the middle of the control electrode 9, and the braille convex point 5 is communicated with the electrorheological fluid cavity 7 through the electrorheological fluid flow channel 8. When the electrorheological valve does not apply a control electric field, electrorheological fluid in the electrorheological fluid cavity 7 can drive the Braille convex points 5 to move through the electrorheological fluid flow channel 8 under the action of the piston 10. When the piston 10 moves rightwards and the electrorheological fluid cavity 8 generates negative pressure, the braille convex points 5 fall; otherwise, the braille bumps 5 are raised. That is, changing the state of the braille bump 5 can be accomplished by the movement of the piston 10 when the control electric field is not applied. When a control electric field is applied, the electrorheological fluid in the electrorheological fluid flow channel 8 is converted into a solid-like state, the valve presents certain valve pressure drop, at the moment, when the pressure generated by the piston 10 in the electrorheological fluid cavity 7 is smaller than the valve pressure drop, the small cavity pressure connected with the Braille convex points 5 at the other end of the valve cannot be changed, and the states of the Braille convex points 5 cannot be changed. Obviously, independent control of the display state of the braille bumps 5 can be achieved by whether or not an external control electric field is applied. When the braille pen is used, the blind person can obtain braille information by touching the braille convex points 5 to finish reading. It can be seen from fig. 1 that the electrode plates of the electrorheological valve are parallel to each other, and the direction of the electric field is perpendicular to the flowing direction of the electrorheological fluid. Under the electric field intensity of the same external control electric field, the smaller the electrode gap is, the lower the external voltage is, the lower the voltage-resistant grade of the corresponding control switch tube is, and the cost and the volume of the electric control part are low; meanwhile, the larger the zero-field flow resistance of the valve is, the smaller the transmission flow is; the refresh rate of the braille bumps 5 is reduced, thereby affecting the reading experience of the user. On the contrary, the larger the electrode gap, the higher the applied voltage; although the refreshing rate of the braille convex points 5 is improved because the valve clearance is enlarged and the zero-field flow resistance is reduced; however, when the applied control voltage is increased, the higher the voltage-resistant grade of the corresponding control switch tube is, the higher the cost and the large volume of the electric control part are, which is not beneficial to product popularization. The root cause of the contradiction between the refreshing rate of the salient points 5 and the control cost is that the electrode gap is the gap 11 of the flow channel 4, and the flowing resistance of the valve and the applied voltage cannot be decoupled.
The braille bump linkage structure of this embodiment, only improve the electrode and the runner 4 structure of above-mentioned structure, the electrode is netted electrode, runner 4 is realized by the sealing connection of through-hole 12 cooperation metal mesh on the insulating gasket 1 and insulating gasket 1, the decoupling zero has been realized to impressed voltage and zero field flow resistance, can guarantee that impressed voltage's invariant reduces even under the prerequisite that reduces the flow resistance, and then can optimize 5 refresh efficiency and control cost of bump simultaneously, do benefit to the product promotion.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
