Currently, the existing products in the automotive market are mainly ordinary shock absorbers. The inventor of the present disclosure finds that the damping coefficient of the common shock absorber is single, and the requirements of safety, smoothness and comfort of the automobile can not be well met under different road conditions. So some medium and high end vehicle models have incorporated adjustable shock absorbers. And more automobile manufacturers introduce an electric control shock absorber system when developing new automobile types. However, the inventors of the present disclosure found that in the automotive field, the control accuracy of the electric control valve applied to the shock absorber is limited, the response is slow, the cost is high, and the requirements cannot be satisfied well.

In this regard, at least one embodiment of the present disclosure provides an adjustable control valve for an electronically controlled shock absorber, comprising an electromagnet, a valve body, a valve control core, and a cavity forming portion. At least part of the electromagnet is configured to generate a corresponding electromagnetic force when a current is passed; the valve body is connected with the electromagnet; the valve control core is arranged in the main cavity of the valve body, and is configured to move along the axial direction of the main cavity of the valve body under the drive of electromagnetic force, and the axial direction of the valve control core is coaxial or parallel to the axial direction of the main cavity of the valve body; the cavity forming part comprises a first reciprocating part, a second reciprocating part and an outer sleeve component, the first reciprocating part and the second reciprocating part are sleeved on the outer side of the valve body, and the first reciprocating part and the second reciprocating part are oppositely arranged along the axial direction of the valve control core; the outer sleeve component is arranged on the outer side of the valve body in a surrounding mode, a first cavity is formed in the peripheral space of the outer sleeve component for the circulation of the main path flow of the target liquid, and the outer sleeve component, the first reciprocating piece, the second reciprocating piece and the valve body are arranged in a surrounding mode to form a second cavity; the valve body and the valve control core are matched to form a third cavity, the third cavity is configured to realize pressure adjustment according to the axial movement of the valve control core, and the third cavity is communicated with the second cavity so as to enable the branch flow of the target liquid to circulate.

The adjustable control valve disclosed by the embodiment of the disclosure adopts a three-cavity design and realizes continuous control of cavity pressure in working through continuous movement of the valve control core, so that the effect of continuously controlling the damping force of the shock absorber can be achieved, and the adjustable control valve has the advantages of high control precision, quick response and lower cost.

At least one embodiment of the present disclosure also provides an electrically controlled shock absorber including the adjustable control valve described above.

Some embodiments of the present disclosure and examples thereof are described in detail below with reference to the attached drawings.

Fig. 1-2 are schematic cross-sectional views of an adjustable control valve provided in some embodiments of the present disclosure, wherein fig. 2 and fig. 1 are drawings having the same features as embodiments of the present disclosure, and different numbers are labeled in fig. 2 than fig. 1, for example, with some numbers not in fig. 1 in fig. 2, to facilitate clarity of illustration of the description and drawings herein.

Fig. 3 is a schematic cross-sectional view of an adjustable control valve provided in further embodiments of the present disclosure. Fig. 4 is an enlarged partial schematic view of fig. 3. Fig. 5 is an enlarged partial schematic view of fig. 4.

For convenience of description, hereinafter, the embodiment of the present disclosure refers to a side of the adjustable control valve of fig. 1 to 4, which is close to the valve control core 3, in the radial direction, as "inside", and a side, which is far from the valve control core 3, as "outside". As used herein, "axial" refers to the direction of the central axis of the adjustable control valve as a whole, which is parallel or coaxial with the axial direction of the valve control core 3. The orientations of the embodiments of the present disclosure are relative positions and do not limit the scope of the present disclosure. It should be noted that, for convenience of description, the embodiments of the present disclosure are further introduced in the drawing directions, such as up, down, left, right, etc., for example, the axial direction of the valve control core 3 is the up-down drawing directions of fig. 1-4, and the radial direction of the adjustable control valve or the valve control core 3 is the left-right drawing directions of fig. 1-4, and these definitions do not affect the azimuth in practical application, and the protection scope of the present disclosure is not affected thereby.

For example, as shown in fig. 1 to 4, an adjustable control valve provided in at least one embodiment of the present disclosure includes an electromagnet 1, a valve body 2, a valve control core 3, and a chamber constituting part 4. At least part of the electromagnet 1 is configured to generate a corresponding electromagnetic force when a current is passed. The valve body 2 is connected with the electromagnet 1. The valve control core 3 is disposed in the main cavity 21 of the valve body 2, and the valve control core 3 is configured to be movable in an axial direction of the main cavity 21 of the valve body 2 under the drive of electromagnetic force, the axial direction of the valve control core 3 being coaxial or parallel to the axial direction of the main cavity 21 of the valve body 2.

For example, the cavity constituting part 4 includes a first reciprocating member 41, a second reciprocating member 42, and a jacket member 43. The first and second reciprocating members 41 and 42 are sleeved outside the valve body 2, and the first and second reciprocating members 41 and 42 are disposed opposite to each other in the axial direction of the valve control core 3.

For example, as shown in fig. 1, the jacket assembly 43 includes a first jacket 431 corresponding to the first reciprocating member 41 and a second jacket 432 corresponding to the second reciprocating member 42. For example, the first shuttle 41 is sleeved on the upper end of the first casing 431, and the second shuttle 42 is sleeved on the lower end of the second casing 432.

For example, the outer jacket member 43 is disposed around (i.e., surrounds) the valve body 2, and the outer space of the outer jacket member 43 forms a first chamber Q1 for the main flow rate of the target liquid to circulate. The outer jacket member 43, the first reciprocating member 41, the second reciprocating member 42 and the valve body 2 together define a second chamber Q2. The valve body 2 and the valve control core 3 cooperate to form a third cavity Q3, the third cavity Q3 is configured to realize pressure adjustment according to the axial movement of the valve control core 3, and the third cavity Q3 is communicated with the second cavity Q2 for the bypass flow circulation of the target liquid.

For example, when the valve control core 3 moves along the axial direction, the pressure release of the third cavity Q3 can be controlled by controlling the size of the release area, so that the pressure of the third cavity Q3 can be adjusted, and the pressure of the second cavity Q2 can be controlled. For example, clearance control is performed by cooperation of a portion to be controlled of the valve body 2 and a control portion of the valve control core 3 hereinafter to control the liquid drain.

In some examples, the first, second, and third chambers Q1, Q2, and Q3 of embodiments of the present disclosure may also be referred to as outer, middle, and inner chambers, respectively, depending on the location of the arrangement. For example, the lumen may also be referred to as a working lumen and the inner lumen may also be referred to as a control lumen. It should be noted that the designations of the components herein are merely exemplary and are not intended to be limiting of the present disclosure, and the scope of the present disclosure is not limited thereto, primarily for convenience of description herein.

The adjustable control valve of the embodiment of the disclosure realizes continuous control of the cavity pressure in work through the design of the inner cavity, the middle cavity and the outer cavity and the continuous movement of the valve control core, thereby achieving the effect of connecting and controlling the damping force of the shock absorber and having the advantages of high control precision, quick response and lower cost.

For example, the electronically controlled damper of the embodiments of the present disclosure includes an adjustable control valve and a hollow link 101, at least a portion of the electromagnet 1 being connected to the hollow link 101. Thus, the adjustable control valve is formed as a built-in valve structure.

In other examples, the electrically controlled shock absorber includes the above-described adjustable control valve and a control valve tube (not shown) to which at least a portion of the electromagnet 1 is fixed. Thus, the adjustable control valve is formed as an external valve structure.

The structure of the adjustable control valve included in the electric control shock absorber according to the embodiments of the present disclosure may refer to the adjustable control valve of any embodiment herein, so the technical effects of the electric control shock absorber may refer to the description of the adjustable control valve herein, and the description thereof will not be repeated herein.

For example, when the electronically controlled damper is operating in the tension end, liquid flows from the upper end to the lower end, such as the path taken by flow a and the path taken by flow B shown in fig. 1. For another example, when the electronically controlled damper is operating at the compression end, liquid flows from the lower end to the upper end, such as the path taken by flow C and the path taken by flow D shown in fig. 1.

For example, as shown in fig. 1 and 2, the electromagnet 1 includes a coil 12, and the coil 12 is configured to generate a corresponding electromagnetic field to generate an electromagnetic force when a current is passed, and to act on the valve control core 3. Thus, the valve control core 3 can move along the axial direction of the main cavity 21 of the valve body 2 under the drive of electromagnetic force, so that the size of the leakage flow area can be controlled, and the pressures of the third cavity Q3 and the second cavity Q2 and the damping force of the shock absorber can be controlled.

For example, as shown in fig. 1 and 2, the adjustable control valve further includes a valve housing 91, and the valve body 2 is coupled to the valve housing 91. This is merely exemplary and is not a limitation of the present disclosure. It should be noted that the valve sleeve 91 and the valve body 2 may be coupled together not only by a threaded coupling method as shown in fig. 1-2, but also by other methods, such as laser welding, riveting, etc., and the embodiments of the present disclosure are not limited thereto.

It should be further noted that, in order to implement the adjusting function of the adjustable control valve according to the embodiments of the present disclosure when applied to the electronically controlled shock absorber, a person skilled in the art may provide, set, for example, other components, not shown, such as a non-magnetic sleeve, in the electromagnet 1 according to specific needs, and the embodiments of the present disclosure are not limited thereto, and because this is not the focus of the description of the embodiments of the present disclosure, the details will not be repeated herein.

For example, as shown in fig. 1, the chamber constituting part 4 further includes a separation seat 44, the separation seat 44 being configured to separate the second chamber Q2 into a first sub-chamber Q1 and a second sub-chamber Q2. The first subchamber q1 is defined by the first outer jacket 431, the first shuttle 41, the valve body 2 and the separating seat 44. The second subchamber q2 is defined by the second outer sleeve 432, the second shuttle 42, the valve body 2 and the separating seat 44.

Embodiments of the present disclosure may separate the middle chamber into upper and lower working areas by a separation housing, thereby separating into a tensile working area and a compressive working area.

In some examples, the separating seat 44 may be sealed at its inner and outer ends by a press fit, or may be provided with a special seal to completely separate the upper and lower portions, as the embodiments of the disclosure are not limited in this respect.

For example, as shown in fig. 1, the adjustable control valve further includes a first hydraulic control valve 61 and a second hydraulic control valve 62. The first hydraulic control valve 61 is connected to the first shuttle 41, and one end of the first shuttle 41 adjacent to the second shuttle 42 in the axial direction of the valve control spool 3. The second hydraulic control valve 62 is connected to the second shuttle 42, and one end of the second shuttle 42 adjacent to the first shuttle 41 in the axial direction of the valve control spool 3.

For example, in the example of fig. 1, the first hydraulic control valve 61 is located at the lower end of the first shuttle 41, and the second hydraulic control valve 62 is located at the upper end of the second shuttle 42. The first hydraulic control valve 61 is fitted over the valve body 2, and the second hydraulic control valve 62 is fitted over the valve body 2.

Embodiments of the present disclosure may control a pressure difference generated when fluid flows through by opening heights of upper and lower hydraulic control valves to control a stretching pressure difference or a compression pressure difference.

For example, the first reciprocating member 41 is a first piston that is reciprocatingly and linearly movable, and the second reciprocating member 42 is a second piston that is reciprocatingly and linearly movable. These are merely exemplary and are not limiting of the embodiments of the present disclosure, and are not intended to be exhaustive or redundant as long as they are components capable of being forced to reciprocate.

In some examples, the first shuttle 41, the second shuttle 42, the first outer jacket 431, and the second outer jacket 432 may be fixedly connected directly or indirectly to the valve body 2.

For example, as shown in fig. 1 and 2, the adjustable control valve further includes a first balance spring 51 located in the first subchamber q1 and a second balance spring 52 located in the second subchamber q2, the axial direction of the second balance spring 52 and the axial direction of the first balance spring 51 being parallel to the axial direction of the valve control core 3, respectively. For example, the first balance spring 51 is fitted over the outside of the valve body 2, and the first balance spring 51 is provided between the first hydraulic control valve 61 and the separation seat 44. For example, the second balance spring 52 is fitted over the outside of the valve body 2, and the second balance spring 52 is provided between the second hydraulic control valve 62 and the separation seat 44.

The hydraulic control valve can be stressed and balanced during movement by balancing the spring force of the spring, and the back pressure of the corresponding hydraulic control valve is regulated.

For example, when the valve control spool 3 is depressurized by moving in the axial direction (see below), the pressure of the second chamber Q2 may decrease, and the first hydraulic control valve 61 may move downward, at which time the first hydraulic control valve 61 may compress the first balance spring 51, and the first balance spring 51 may force-balance the first hydraulic control valve 61 by the spring force. This is merely exemplary and is not intended to limit the embodiments of the present disclosure to facilitate the reader's understanding of the teachings of the embodiments of the present disclosure.

In some examples, the cavity formation 4 and the valve body 2 are symmetrical or approximately symmetrical, respectively, about an axis of the valve control core 3. Thus, the adjustable control valve disclosed by the embodiment of the invention has the advantages of stable structure, simple processing technology and lower cost. Of course, this is merely exemplary and is not a limitation of the present disclosure.

It should be noted that, the disclosure mainly uses an approximately symmetrical adjustable control valve as an example, so for some parts or positions that are vertically or laterally symmetrical in the drawings, only reference numerals on one side are labeled in the disclosure, so that the drawings are concise and clear, but this does not affect understanding of technical solutions of embodiments of the disclosure by those skilled in the art, and does not affect the protection scope of the disclosure.

For example, as shown in fig. 1, the outer surfaces of the first and/or second reciprocating members 41 and 42 are respectively sleeved with piston rings 47, so that axial sealability and low friction force of up-down sliding can be provided.

For example, as shown in fig. 1, a seal ring 63 is provided between the first hydraulic control valve 61 and/or the second hydraulic control valve 62 and the valve body 2, respectively, so that axial tightness can be provided.

For example, as shown in fig. 1 and 2, the adjustable control valve further includes a third spring 53, the third spring 53 is connected to an end of the valve control core 3 remote from the electromagnet 1 (i.e., the third spring 53 is connected to a lower end of the valve control core 3), and the electromagnet 1 includes a fourth spring 11 connected to the other end of the valve control core 3 (i.e., an upper end of the valve control core 3). As such, embodiments of the present disclosure may provide pre-compression and elastic stiffness by providing springs.

For example, as shown in fig. 1, the adjustable control valve further includes an adjustment nut 71 and a bolt 72, the adjustment nut 71 being provided on a side of the valve body 2 remote from the electromagnet 1, the adjustment nut 71 being configured to adjust the preload of the third spring 53. The bolt 72 is located on the side of the adjustment nut 71 remote from the electromagnet 1, the bolt 72 being configured to fasten the adjustable control valve such that the entire adjustable control valve can be locked.

For example, as shown in fig. 2, each of the first hydraulic control valve 61 and the second hydraulic control valve 62 is provided with a first through hole 6a, respectively, on both sides in the radial direction of the valve control spool 3 to form at least a part of the second chamber Q2.

For example, in the example of fig. 2, the first through holes 6a are opened on the left and right sides of the first hydraulic control valve 61, respectively. In this way, the chamber portion between the lower end of the first hydraulic control valve 61 and the separation seat 44 communicates with the first through hole 6a of the first hydraulic control valve 61 to form the first sub-chamber q1. For example, in the example of fig. 2, the left and right sides of the second hydraulic control valve 62 are respectively opened with the first through holes 6a. In this way, the chamber portion between the upper end of the second hydraulic control valve 62 and the separation seat 44 communicates with the first through hole 6a of the second hydraulic control valve 62 to form the second sub-chamber q2.

For example, as shown in fig. 2, each of the first shuttle 41 and the second shuttle 42 is provided with a second through hole 4a, respectively, on both sides in the radial direction of the valve control core 3. For example, in the example of fig. 2, the left and right sides of the first shuttle 41 are respectively opened with the second through holes 4a, and the left and right sides of the second shuttle 42 are respectively opened with the second through holes 4a.

For example, the axial direction of the first through hole 6a and the axial direction of the second through hole 4a are respectively parallel to the axial direction of the valve control core 3, and the first through hole 6a and the corresponding second through hole 4a are provided so as to be at least partially aligned so as to communicate with each other for providing a flow space of liquid. Illustratively, the first through-holes 6a are coaxially disposed with the corresponding second through-holes 4 a. Of course, this is merely exemplary and is not a limitation of the present disclosure.

For example, as shown in fig. 2, the second through hole 4a of the first shuttle 41 and the second through hole 4a of the second shuttle 42 are respectively communicated with the first chamber Q1, so that the main-path flow amount flowing in from the second through hole 4a can pass through, for example, the fluid path a and the fluid path C shown in fig. 2. For example, the second through hole 4a of the first shuttle 41 may communicate with the first cavity Q1 through the outer passage of the first shuttle 41, and the second through hole 4a of the second shuttle 42 may communicate with the first cavity Q1 through the outer passage of the second shuttle 42.

Based on the above, the embodiment of the disclosure can obtain various damping forces of the electric control shock absorber required in actual use through ingenious design of the three cavities which are sequentially arranged inside and outside.

In some examples, the adjustable control valve further includes an inner through spring piece 45, the inner through spring piece 45 being provided at one end of the first and second reciprocators 41 and 42, respectively, which are distant from each other in the axial direction of the valve control core 3. For example, as shown in fig. 1 and 2, the upper end of the first reciprocating member 41 is provided with an inner passing spring piece 45, and the lower end of the second reciprocating member 42 is also provided with an inner passing spring piece 45. The channel of the first cavity Q1 of the embodiment of the present disclosure may be plugged unidirectionally by the upper end of the inner through-spring piece 45 provided.

For example, as shown in fig. 1 and 2, an inner through-spring piece 45 is enclosed on the outside of the valve body 2, the inner through-spring piece 45 is provided with an inner through-hole, and the inner through-hole of the inner through-spring piece 45 and the corresponding second through-hole 4a are provided so as to be at least partially aligned so as to communicate with each other for providing a flow space of liquid.

For example, as shown in fig. 1 and 2, the adjustable control valve further includes: the first valve plate 48 and/or the second adjustment valve plate 46 provided between the first shuttle 41 and the first hydraulic control valve 61, and/or the first valve plate 48 and/or the second adjustment valve plate 46 provided between the second shuttle 42 and the second hydraulic control valve 62. For example, the first valve plate 48 and/or the second valve plate 46 may be used to elastically open each corresponding fluid channel and adjust the flow rate using the through holes.

The opening of the main circuit corresponding to the main circuit flow rate of the target liquid of the embodiment of the present disclosure may be controlled by the first hydraulic control valve 61 and the second hydraulic control valve 62, and the magnitude of the control liquid flow rate may be adjusted by the valve plate.

In some examples, the valve body 2 includes at least one lateral valve port 22, the lateral valve port 22 communicating with the main chamber 21 and the second chamber Q2, respectively. For example, the lateral valve port 22 includes: at least one first lateral valve port in communication with the first subchamber Q1 and at least one second lateral valve port in communication with the second subchamber Q2 to form at least a portion of the third chamber Q3. Embodiments of the present disclosure may continuously control the damper damping force of the upper and lower regions of the middle chamber.

The above-described embodiments of the present disclosure control the damping force of the electronically controlled shock absorber by forming a control chamber inside the valve body and implementing pressure control of the middle chamber through pressure control of the control chamber.

For example, as shown in fig. 1 and 2, the valve control core 3 is substantially cylindrical, and one end of the lateral valve port 22 in the radial direction of the valve control core 3, which is away from the outer jacket member 43, is provided as an end surface having a curvature matching that of the valve control core 3, so that the third chamber Q3 is configured to achieve pressure adjustability of the third chamber Q3 by opening and closing the lateral valve port 22 with respect to the outer surface in the radial direction of the valve control core 3. Thus, the control inner cavity of the present disclosure has the advantages of simple structure, convenient operation and lower cost. For example, one end of the lateral valve port 22 of the present disclosure, which is far from the outer jacket member 43 in the radial direction of the valve control stem 3, may be curved or planar as long as it matches the outer surface of the portion corresponding to the valve control stem 3 so that the valve control stem 3 can close the lateral valve port 22 or open the lateral valve port 22, to which the embodiment of the present disclosure is not limited.

For example, as shown in fig. 1, when the outer surface of the valve control core 3 in the radial direction blocks the lateral valve port 22 at the time of up-and-down movement of the valve control core 3, the pressure in the second chamber Q2 is maximized, and the damper force is maximized. For example, when the radially outer surface of the valve control spool 3 and the opening of the lateral valve port 22 are larger (i.e., the drain area is larger), the back pressure of the first hydraulic control valve 61 or the second hydraulic control valve 62 is smaller, and the shock absorber damping force is smaller. Conversely, the greater the damping force of the shock absorber.

For example, in the example of fig. 1 and 2, when the valve control stem 3 moves up and down, during a part of the valve control stem 3 (i.e., the control portion of the valve control stem 3) gradually moves from the lower end of the lateral valve port 22 to the upper end of the lateral valve port 22 (i.e., the inner surface of the lateral valve port 22 is the mating portion to be controlled that correspondingly mates with the control portion of the valve control stem 3), the pressure in the third chamber Q3 gradually changes, so that the pressure in the second chamber Q2 may gradually change. Thus, embodiments of the present disclosure provide for the passage of a control flow (hereinafter control flows B and D, which may also be referred to as branch flows) between the mating portion to be controlled and the control portion of the valve control core by continuous movement of the valve control core, the magnitude of the flow passing being inversely related, e.g., inversely related, to the pressure of the second chamber Q2.

The embodiment of the present disclosure uses electromagnetic force to adjust the position of the valve control core 3, thereby achieving the purpose of continuously controlling the pressure of the second chamber Q2, that is, continuously controlling the damping force of the shock absorber.

In some examples, the cavity forming part 4 comprises a to-be-controlled fitting part located on the inner wall of the main cavity 21 of the valve body 2, the to-be-controlled fitting part being for cooperating with the control part of the valve control core 3 to control the pressure of the third cavity Q3 and thus the pressure of the second cavity Q2. For example, the mating portion to be controlled is located between the first lateral valve port of the valve body 2 and the second lateral valve port of the valve body 2 in the axial direction of the valve control spool 3.

For example, as shown in fig. 4, the mating portion to be controlled includes a first inner valve assembly 81, a second inner valve assembly 82, and a first positioning ring 83 located between the first inner valve assembly 81 and the second inner valve assembly 82 in the axial direction of the valve control spool 3. The first positioning ring 83 is used to position the inner valve body of the first inner valve assembly 81 and the inner valve body of the second inner valve assembly 82 to form a fluid space. The axial direction of the first inner valve assembly 81 and the axial direction of the second inner valve assembly 82 are respectively parallel to the axial direction of the valve control spool 3.

In some examples, the first internal valve component 81 and/or the second internal valve component 82 are each one-way valves.

For example, as in the example shown in fig. 4 and 5, the check valve includes an inner valve body 811 (e.g., an inner valve body 801a of the first inner valve assembly 81 and an inner valve body 801b of the second inner valve assembly 82) and an inner valve spring piece (e.g., an inner valve spring piece 802a corresponding to the inner valve body 801a and an inner valve spring piece 802b corresponding to the inner valve body 801 b) provided on a side of the inner valve body 811 near the first positioning ring 83.

For example, the inner valve body 801a and/or the inner valve body 801b are annular. This is merely exemplary and is not a limitation of the present disclosure.

For example, as shown in fig. 5, the valve control cartridge 3 includes a control portion 31 that engages with the engagement portion to be controlled, and thus, the pressure of the second chamber Q2 is controlled by the movement of the valve control cartridge 3 in the axial direction.

For example, as shown in fig. 4 and 5, the inner valve body 811 is provided with third through holes 8a on both sides in the radial direction of the valve control core 3, respectively, and the inner bores 8b of the first positioning ring 83 are at least partially aligned with the third through holes 8a of the first inner valve assembly 81 and/or the third through holes 8a of the second inner valve assembly 82, respectively, so as to communicate with each other to form at least a part of the third chamber Q3.

In some examples, the outer surface of the first portion of the valve control core 3 (i.e., the control portion 31 described above) is provided with an uneven shape configured such that the clearance formed by the valve control core 3 with the mating portion to be controlled of the valve body 3 is adjustable when the valve control core 3 moves in the axial direction, thereby making the pressure of the third chamber Q3 adjustable when the valve control core 3 moves in the axial direction. Therefore, the adjustable control valve not only can achieve the purpose of continuously controlling the damping force of the shock absorber, but also has high control precision, quick response and wide application range.

For example, as shown in fig. 5, the concave-convex shape of the outer surface of the control portion 31 of the valve control core 3 includes at least two sections of depressions 301, the outer surfaces of bosses 302 corresponding to the depressions 301 are respectively flat surfaces, and the outer diameter of the bosses 302 is equal to the inner diameter of an inner valve body 811 (for example, an inner valve body 801a or an inner valve body 801 b).

In some examples, the dimension of the recess 301 in the axial direction of the valve control stem 3 is greater than the dimension of the first inner valve assembly 81 or the second inner valve assembly 82 in the axial direction of the valve control stem 3. For example, the dimension of the recess 301 in the axial direction of the valve control stem 3 (e.g., the largest dimension of the recess 301 in the axial direction of the valve control stem 3, i.e., the dimension of the leftmost end of the recess 301 in the axial direction of the valve control stem 3) is equal to the sum of the dimension of the first positioning ring 83 in the axial direction of the valve control stem 3 and the dimension of the first inner valve assembly 81 or the second inner valve assembly 82 in the axial direction of the valve control stem 3.

In this way, the present disclosure can realize that the outer surface of the valve control core 3 in the radial direction blocks the mating portion to be controlled of the valve body 2 so that the pressure in the second chamber Q2 is maximized, and the design can make the response of control faster. Of course, this is merely exemplary and not limiting of the present disclosure, as the dimension of the recess 301 in the axial direction of the valve control stem 3 may also be slightly greater than the sum of the dimension of the first positioning ring 83 in the axial direction of the valve control stem 3 and the dimension of the first inner valve assembly 81 or the second inner valve assembly 82 in the axial direction of the valve control stem 3, and as the dimension of the recess 301 in the axial direction of the valve control stem 3 may also be slightly less than the sum of the dimension of the first positioning ring 83 in the axial direction of the valve control stem 3 and the dimension of the first inner valve assembly 81 or the second inner valve assembly 82 in the axial direction of the valve control stem 3, which is not limiting of the embodiments of the present disclosure.

In some examples, the outer surface of the boss 302 has a smaller dimension in the axial direction of the valve control core 3 than the first positioning ring 83. In this way, the present disclosure enables the bypass flow rate D to pass through the gap between the inner valve body 801a and the control portion 31 of the valve body 3 and the bypass flow rate B to pass through the gap between the inner valve body 801B and the control portion 31 of the valve body 3, thereby enabling various electric control shock absorber damping forces required in actual use.

For example, as shown in fig. 4, the outer surface of the second portion of the valve control cartridge 3 is provided as an inner groove 303 and is configured to mate with the lateral valve port 22 such that the gap formed by the valve control cartridge 3 and the mating portion to be controlled of the valve body 3 communicates with the lateral valve port 22 for bypass flow communication such that liquid can flow into or out of the third chamber Q3. For example, the second portion of the valve control cartridge 3 is located on the side of the adjacent inner valve body 811 remote from the first positioning ring 83.

In some examples, a side of one of the first and second internal valve assemblies 81, 82 remote from the electromagnet 1 is provided with a second locating ring 84.

It should be noted that, for clarity and brevity, in the embodiment of the adjustable control valve shown in fig. 3-4, the differences between the adjustable control valve shown in fig. 3-4 and the adjustable control valve shown in fig. 1-2 are mainly described, and the same and similar points may be referred to the embodiment of the adjustable control valve shown in fig. 1-2, and are not repeated herein.

It should be further noted that, the form of the to-be-controlled matching portion corresponding to the third cavity Q3 of the adjustable control valve according to the embodiment of the present disclosure is not limited to the examples related to fig. 1-2 and fig. 3-4, but may be any other reasonable form, as long as the pressure of the third cavity Q3 can be controlled by the movement of the valve control core, so as to control the pressure of the second cavity Q2, which is not exhaustive and not described in detail in the embodiments of the present disclosure.

At least one embodiment of the present disclosure provides a method for operating an electronically controlled damper at a tension end, including:

for example, referring to the right side of the adjustable control valve in fig. 3 and 4:

(1) The main flow A of the target liquid passes through the inner through hole of the upper inner through spring piece 45 and the second through hole 4a of the first reciprocating member 41, and then passes through the outer channel of the first reciprocating member 41, so that the main flow A enters the first cavity Q1, then passes through the outer channel of the second reciprocating member 42, and the lower inner through spring piece 45 is opened, so that the main flow A reaches the lower part of the adjustable control valve;

(2) The branch flow B (namely, the control flow B) passes through the regulating hole of the second regulating valve plate 46 above and the first through hole 6a of the first hydraulic control valve 61, and continues to circulate in the first subchamber Q1 of the second chamber Q2, and then enters the inner channel of the inner valve body 811 in the third chamber Q3; then, the bypass flow B continues to circulate, and enters the second subchamber Q2 of the second chamber Q2, and then sequentially passes through the first through hole 6a of the second hydraulic control valve 62, the second adjusting valve plate 46 (open), the second through hole 4a of the second reciprocating member 42, and the lower inner through spring piece 45, so that the bypass flow B reaches the lower part of the adjustable control valve.

For example, as shown in fig. 3 and 4, when the electronically controlled damper is operated at the extension end, when the bypass flow B enters the third chamber Q3, the bypass flow B at least sequentially passes through the inner hole of the inner valve body 801a and the inner valve spring piece 802a (open), so that the bypass flow B may enter the lower end of the mating portion to be controlled in a certain state, and then sequentially passes through the second hydraulic control valve 62, the second adjusting valve piece 46, the second reciprocating member 42, and the lower inner through spring piece 45, thereby reaching the lower portion of the adjustable control valve.

The at least one embodiment also provides a method for operating the electric control shock absorber at the compression end, which specifically comprises the following steps:

for example, referring to the left side of the adjustable control valve in fig. 3 and 4:

(1) The main flow C of the target liquid passes through the inner through hole of the lower inner through spring piece 45, the second through hole 4a of the second reciprocating piece 42 and then passes through the outer channel of the second reciprocating piece 42, so that the main flow C enters the first cavity Q1, then passes through the outer channel of the first reciprocating piece 41, and the upper inner through spring piece 45 is opened, so that the main flow C reaches the upper part of the adjustable control valve;

(2) The bypass flow D (control flow D) passes through the adjustment hole of the second adjustment valve plate 46 below, the first through hole 6a of the second hydraulic control valve 62, and continues to flow in the second subchamber Q2 of the second chamber Q2, and then enters the inner passage of the inner valve body 811 in the third chamber Q3; then, the bypass flow D continues to circulate, and enters the first subchamber Q1 of the second chamber Q2, and then sequentially passes through the first through hole 6a of the first hydraulic control valve 61, the second adjusting valve plate 46 (open), the second through hole 4a of the first reciprocating member 41, and the upper inner through spring piece 45, so that the bypass flow D reaches the upper part of the adjustable control valve.

For example, as shown in fig. 3 and 4, when the electronically controlled damper is operated at the compression end, when the bypass flow D enters the third chamber Q3, the bypass flow D at least sequentially passes through the inner hole of the inner valve body 801b and the inner valve spring piece 802b (open), so that the bypass flow D can enter the upper end of the mating portion to be controlled in a certain state, and then sequentially passes through the first hydraulic control valve 61, the second adjustment valve piece 46, the first reciprocating member 41, and the upper inner through spring piece 45, thereby reaching the upper side of the adjustable control valve.

Fig. 6A is a schematic diagram of a second state obtained after the valve control spool 3 is moved up by 0.1mm based on the first state shown in fig. 5, wherein the first state of fig. 5 is a state where the stroke of the valve control spool 3 is zero, and the second state of fig. 6A is a state where the stroke of the valve control spool 3 is 0.1 mm.

For example, as shown in fig. 5, the gap between the upper end of the inner valve body 801a and the control portion 31 of the valve body 3 and the gap between the upper end of the inner valve body 801b and the control portion 31 of the valve body 3 are both zero, that is, the outer surface in the radial direction of the valve control core 3 seals the fitting portion to be controlled of the valve body 2, the pressure in the second chamber Q2 is maximized, and thus the shock absorber damping force is maximized.

For example, as shown in fig. 6A, the bypass flow rate D may pass through a gap between the inner valve body 801a and the control portion 31 of the valve body 3 after passing through the inner bore of the inner valve body 801b and the inner valve spring piece 802b in order. After the bypass flow B passes through the inner hole of the inner valve body 801a and the inner valve spring piece 802a in sequence, the bypass flow B cannot pass through continuously because the gap between the upper end of the inner valve body 801B and the control portion 31 of the valve body 3 is zero. Therefore, in the state of fig. 6A, the tensile damping force is large, and since the stroke amount of the valve control core 3 is small, the gap between the inner valve body 801a and the valve body 3 is relatively small, and thus the compressive damping force is still large.

It should be noted that fig. 6A to fig. 6D are only schematic diagrams, and fig. 6A, fig. 6B, fig. 6C, or fig. 6D illustrate the branch flow B and the branch flow D at the same time, which are mainly for convenience in describing the state, the structure, and the principle of the scheme of the to-be-controlled matching portion and the valve control core in the embodiments of the present disclosure, which are not limited to the embodiments of the present disclosure, and are not inconsistent with the foregoing description of the present disclosure, and are not repeated herein.

Fig. 6B is a schematic view of a third state obtained after the valve control core 3 is moved upward by 0.6mm based on the second state shown in fig. 6A, the third state of fig. 6B being a state when the stroke of the valve control core 3 is 0.7 mm.

For example, as shown in fig. 6B, the bypass flow rate D may pass through a gap between the inner valve body 801a and the control portion 31 of the valve body 3; since the dimension (e.g., 0.7 mm) of the outer surface of the boss 302 in the axial direction of the valve control core 3 is not smaller than (e.g., equal to) the stroke (e.g., 0.7 mm) of the valve control core 3, the clearance between the upper end of the inner valve body 801B and the control portion 31 of the valve body 3 is zero, and the bypass flow B cannot continue to pass through. Therefore, in the state of fig. 6B, the tensile damping force is large, and since the gap between the inner valve body 801a and the control portion 31 of the valve body 3 becomes large, the compressive damping force becomes small as compared with fig. 6A.

Fig. 6C is a schematic view of a fourth state obtained after the valve control core 3 is moved further upward by 0.6mm based on the third state shown in fig. 6B, and the fourth state of fig. 6C is a state when the stroke of the valve control core 3 is 1.3 mm.

For example, as shown in fig. 6C, the bypass flow rate D may pass through a gap between the inner valve body 801a and the control portion 31 of the valve body 3, and the bypass flow rate B may also pass through a gap between the inner valve body 801B and the control portion 31 of the valve body 3. Therefore, in the state of fig. 6C, the tensile damping force becomes smaller, and the compressive damping force becomes smaller.

Fig. 6D is a schematic view of a fifth state obtained after the valve control core 3 is moved further upward by 0.6mm based on the fourth state shown in fig. 6C, and the fifth state of fig. 6D is a state when the stroke of the valve control core 3 is 1.9 mm.

For example, as shown in fig. 6D, the bypass flow B may also pass through a gap between the inner valve body 801B and the control portion 31 of the valve body 3; since the gap between the lower end of the inner valve body 801a and the control portion 31 of the valve body 3 is zero, the bypass flow D cannot continue to pass through. Therefore, in the state of fig. 6D, the tensile damping force is small and the compressive damping force is large.

Therefore, the adjustable control valve of the above-described embodiment of the present disclosure can obtain various electric control shock absorber damping forces required in actual use through the above-described smart design.

The following points need to be described:

(1) The drawings of the embodiments of the present disclosure relate only to the structures to which the embodiments of the present disclosure relate, and reference may be made to the general design for other structures.

(2) The embodiments of the present disclosure and features in the embodiments may be combined with each other to arrive at a new embodiment without conflict.

The foregoing is merely specific embodiments of the disclosure, but the scope of the disclosure is not limited thereto, and the scope of the disclosure should be determined by the claims.
