Description

[0001] This invention relates to the field of high-frequency response directional valve technology, specifically to a high-speed response valve based on the coordinated drive of an electromagnet and a motor. Background Technology

[0002] High-frequency response directional control valves are key hydraulic components designed to meet the demands of high dynamic response and precise control, and are widely used in engineering machinery, aerospace, and automotive industries. The background technology primarily focuses on improving the response speed, frequency adaptability, and control accuracy of hydraulic systems. This is achieved through improvements in electromagnetic drive and valve core structure design, ensuring rapid switching and precise flow control under high-frequency operating conditions. The development of this technology benefits from advancements in electromagnetic field optimization, advanced materials, and manufacturing processes, meeting the stringent requirements of high-speed hydraulic equipment and servo control systems.

[0003] Improving the electromagnetic drive and valve core structure design to ensure rapid switching and precise flow control under high-frequency operating conditions is a pressing issue. To address this, a high-speed response valve based on the coordinated drive of an electromagnet and a motor is proposed. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to combine the advantages of rapid response of electromagnet and precise positioning of motor to facilitate high-precision control of flow and pressure, and provides a high-speed response valve based on the coordinated drive of electromagnet and motor.

[0005] This invention solves the aforementioned technical problems through the following technical solution: The invention includes a motor, an electromagnet, a valve body, a valve core, a valve sleeve, and a rotating connecting plate. The motor is disposed at one end of the valve body, and the electromagnet is disposed at the other end of the valve body. The valve core is embedded inside the valve sleeve, and the valve sleeve is embedded inside the valve body. The motor is rotatably connected to the valve sleeve via the rotating connecting plate, enabling it to drive the valve sleeve to move left and right. The motor is slidably connected to one end of the valve core via the rotating connecting plate, and the electromagnet is connected to the other end of the valve core. Under the drive of the electromagnet, the valve core, driven by the motor, can perform a helical left and right translation. Through the coordinated drive between the valve sleeve and the valve core, the fit between the protrusion of the valve core and the groove of the valve sleeve can be changed, thereby controlling the flow rate and pressure.

[0006] Furthermore, the output shaft of the rotor in the motor is connected to the rotating connecting plate by a key. The rotating connecting plate is a circular plate with a raised ball at its edge that mates with the valve sleeve, a keyhole at its center that mates with the output shaft of the rotor, and a slide rail on one side that slidably connects with the valve core.

[0007] Furthermore, one end of the valve core is provided with a valve core guide rail, which is slidably connected to a slide rail on a rotating connecting plate, and the other end is provided with a baffle. The baffle is provided with a valve core connector with a hemispherical top, which is rotatably connected to the valve sleeve. Multiple valve core protrusions are provided on the outside of the valve core.

[0008] Furthermore, one end of the valve sleeve is fitted with an inner guide rail, and the other end is provided with an outer guide rail. Both the inner and outer guide rails are annular guide rails. The inner and outer guide rails correspond to the protruding sphere on the rotating connecting plate and the valve core connector on the baffle, and their contact surfaces are all wavy surfaces. The valve sleeve has multiple valve sleeve grooves along the axial direction, and each valve sleeve groove has an oil hole at the bottom for oil to enter and exit.

[0009] Furthermore, the electromagnet includes a magnetically conductive component, an armature, a coil, and a fixed iron core. The coil is wound on a coil frame outside the fixed iron core. The armature and the magnetically conductive component are both located inside the fixed iron core, and the magnetically conductive component is fixedly connected to the valve body. A guide rod is also provided at the end of the valve core. The guide rod passes through the magnetically conductive component and is inserted into the armature and connected to it by a key. A reserved slot for placing a spring is opened on the side of the magnetically conductive component near the armature. One end of the spring contacts the magnetically conductive component, and the other end contacts the armature. The armature contacts the fixed iron core.

[0010] Furthermore, the protrusion on the valve core closest to the baffle and the baffle are respectively provided with a first flow guide hole and a second flow guide hole for the valve core. An oil hole is provided at the edge of the magnetic conductive component. The first flow guide hole, the second flow guide hole for the valve core and the oil hole on the magnetic conductive component guide the oil into the electromagnet.

[0011] Furthermore, the valve body is provided with an oil inlet, an oil outlet, a first working oil port, a second working oil port, and a curved flow channel. The oil inlet is provided with an eleventh sealing ring for sealing, the oil outlet is provided with a ninth sealing ring for sealing, the first working oil port is provided with a tenth sealing ring for sealing, and the second working oil port is provided with a twelfth sealing ring for sealing.

[0012] Furthermore, the valve sleeve is sealed to the valve body by a third sealing ring and an eighth sealing ring, the valve sleeve is sealed to the oil outlet by a third sealing ring and a fourth sealing ring, the valve sleeve is sealed to the first working oil port by a fourth sealing ring and a fifth sealing ring, the valve sleeve is sealed to the oil inlet by a fifth sealing ring and a sixth sealing ring, and the valve sleeve is sealed to the second working oil port by a sixth sealing ring and a seventh sealing ring.

[0013] Furthermore, during the left and right translation of the valve sleeve and valve core, when the groove of the valve sleeve and the protrusion of the valve core are fully engaged, no oil enters the curved oil passage of the valve body. When the groove of the valve sleeve and the protrusion of the valve core are engaged on the right side, the oil inlet is connected to the first working oil port, and the second working oil port is connected to the oil outlet through the curved flow channel. When the groove of the valve sleeve and the protrusion of the valve core are engaged on the left side, the oil inlet is connected to the second working oil port, and the first working oil port is connected to the oil outlet through the curved flow channel. Here, "fully engaged" means that the protrusion of the valve core completely blocks the oil hole on the groove of the valve sleeve. "Right-side engagement" means that the protrusion of the valve core is located on the right side of the groove of the valve sleeve, and the oil hole on the groove of the valve sleeve is not completely blocked. "Left-side engagement" means that the protrusion of the valve core is located on the left side of the groove of the valve sleeve, and the oil hole on the groove of the valve sleeve is not completely blocked.

[0014] Furthermore, the high-speed response valve also includes a left end cover and a right end cover. The left end cover is connected to one end of the valve body and is located outside the motor. The right end cover is connected to the other end of the valve body and is located outside the electromagnet.

[0015] Compared with the prior art, the present invention has the following advantages: This high-speed response valve based on the coordinated drive of an electromagnet and a motor generates a magnetic field when the electrodes are energized, which in turn generates an electromagnetic force between the copper coil wound on the rotor and the constant magnetic field of the magnet, thereby causing the rotor to rotate. The rotor rotation drives the rotating connecting plate with the protruding ball to rotate, causing the valve sleeve to translate left and right. When the coil wound on the coil frame is energized, the armature drives the valve core to translate left and right. Due to the cooperation between the slide rail on the rotating connecting plate and the slide rail at the bottom of the valve core, when the rotor rotates, it drives the valve core with the valve core connector and the armature to translate left and right in a spiral manner. Through the coordinated drive between the valve sleeve and the valve core, three configurations can be achieved between the oil ports on the valve body: when the protrusion of the valve core fully engages with the groove of the valve sleeve, no oil enters; when the protrusion of the valve core engages with the right side of the groove of the valve sleeve, the oil inlet connects to the first working oil port, and the second working oil port connects to the oil outlet through a curved flow channel; when the protrusion of the valve core engages with the left side of the groove of the valve sleeve, the oil inlet connects to the second working oil port, and the first working oil port connects to the oil outlet through a curved flow channel. By employing a coordinated control method using an electromagnet and a motor, combining the rapid response of the electromagnet with the precise positioning of the motor, high-precision control of flow rate and pressure can be achieved.

[0027] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0028] like Figures 1-10As shown, the present invention provides a technical solution: a high-speed response valve based on the coordinated drive of an electromagnet and a motor, comprising a rotor 24. The rotor 24, together with a first bushing 22, a cover 2, an electrode 23, a magnet 3, a second bushing 5, and an outer cover 4, constitute a motor. When the electrode 23 is energized, a magnetic field is generated on the copper coil wound on the rotor 24. This magnetic field interacts with the constant magnetic field of the magnet 3 to form an electromagnetic force. The rotor 24 begins to rotate under the action of this electromagnetic force, and the rotational speed and direction of the rotor 24 can be changed by controlling the direction and magnitude of the current.

[0029] In this embodiment, the first bushing 22 is fixed to the cover 2, and the second bushing 5 is fixed to the motor connector 26. Both the first bushing 22 and the second bushing 5 are connected to the rotor 24. The first bushing 22 and the second bushing 5 can ensure that the rotor 24 remains stable during rotation, reduce friction, and extend the service life of the motor. The outer cover 4 is fixed to the motor connector 26 by six clamping bolts 25, and the motor connector 26 is fixed to the left end cover 1.

[0030] In this embodiment, the output shaft of the rotor 24 is keyed to the rotating connecting plate 27. As the rotor 24 rotates, it drives the rotating connecting plate 27 to rotate.

[0031] In this embodiment, the rotating connecting plate 27 is a circular plate with a rotating connecting plate protrusion sphere 27a at its edge that cooperates with the inner guide rail 7 of the valve sleeve, a keyhole 27b at its center that cooperates with the output shaft of the rotor 24, and a rotating connecting plate slide rail 27c on one side that is slidably connected with the valve core guide rail 10a.

[0032] In this embodiment, the protruding sphere 27a of the rotating connecting plate cooperates with the inner guide rail 7 on the valve sleeve 8. As the rotor 24 rotates, it drives the rotating connecting plate 27 to rotate, causing the valve sleeve 8 to move left and right. The slide rail 27c of the rotating connecting plate cooperates with the valve core guide rail 10a. As the rotor 24 rotates, it drives the rotating connecting plate 27 to rotate. The baffle of the valve core 10 is provided with a valve core connector 16 (cylinder with a hemispherical top), which cooperates with the outer guide rail 43 of the valve sleeve. This causes the rotor 24 to rotate, driving the rotating connecting plate 27 to rotate. Then, the rotating connecting plate 27 drives the valve core 10 and the valve core connector 16 to rotate. Finally, the coordinated left and right translation of the valve core 10 is achieved through the operation of both ends of the valve sleeve 8.

[0033] In this embodiment, a valve core guide rail 10a is fixed at one end of the valve core 10, and a baffle is fixed at the other end. A plurality of valve core protrusions 10b are provided on the outside of the valve core 10. The valve core protrusion 10b closest to the baffle and the baffle are respectively provided with a first valve core guide hole 10c and a second valve core guide hole 10d, which are used to guide oil into the interior of the electromagnet structure.

[0034] In this embodiment, one end of the valve sleeve 8 is provided with an inner valve sleeve guide rail 7 (coaxially arranged), and the other end is provided with an outer valve sleeve guide rail 43 (coaxially arranged). Both the inner valve sleeve guide rail 7 and the outer valve sleeve guide rail 43 are annular guide rails, and the diameter of the inner valve sleeve guide rail 7 is smaller than the diameter of the outer valve sleeve guide rail 43. The contact surfaces of the inner valve sleeve guide rail 7 and the outer valve sleeve guide rail 43 with the convex ball 27a of the rotating connecting plate and the valve core connector 16 are wavy surfaces, which, together with the convex ball 27a of the rotating connecting plate and the valve core connector 16, enable the left and right translation of the valve sleeve 8 and the valve core 10.

[0035] In this embodiment, the valve sleeve 8 is provided with a plurality of grooves along the axial direction, and each groove has an oil hole at the bottom for oil to enter and exit.

[0036] In this embodiment, a valve sleeve limiting block 44 is provided at one end of the valve sleeve 8 near the inner guide rail 7 for limiting the valve sleeve. This block cooperates with the limiting groove provided at the corresponding position on the valve body 37 to limit the valve sleeve 8.

[0037] In this embodiment, the valve sleeve 8 is sealed to the valve body 37 by the third sealing ring 9 and the eighth sealing ring 36, the valve sleeve 8 is sealed to the oil outlet 29 by the third sealing ring 9 and the fourth sealing ring 11, the valve sleeve 8 is sealed to the first working oil port 31 by the fourth sealing ring 11 and the fifth sealing ring 12, the valve sleeve 8 is sealed to the oil inlet 33 by the fifth sealing ring 12 and the sixth sealing ring 13, and the valve sleeve 8 is sealed to the second working oil port 35 by the sixth sealing ring 13 and the seventh sealing ring 14.

[0038] In this embodiment, coil 19 is wound on coil frame 18. The outer side of coil 19 cooperates with electromagnet end cap 20. Electromagnet end cap 20 has a fixed iron core 42 inside, and a magnetic shielding ring 40 is provided in the middle of fixed iron core 42 to effectively reduce magnetic leakage. Electromagnet end cap 20 cooperates with right end cap 21. A magnetic conductive component 38 is embedded inside fixed iron core 42. The magnetic conductive component 38 has a groove that can cooperate with valve core 10 and is penetrated by a guide rod provided at the end of valve core 10. Oil holes are provided around magnetic conductive component 38 to allow oil to enter the electromagnet structure. A groove is opened at one end of magnetic conductive component 38 near armature 41 for placing spring 39. One end of spring 39 contacts magnetic conductive component 38 and the other end contacts armature 41. One end face of fixed iron core 42 contacts armature 41.

[0039] In this embodiment, the guide rod at the end of the valve core 10 is keyed to the armature 41, so that when the valve core 10 is rotated, the armature 41 is also rotated. After the coil 19 is energized, the direction of the current can be controlled, so that the armature 41 moves the valve core 10 left and right under the action of magnetic force. The operation of both ends of the valve sleeve 8 causes the valve core 10 to move left and right in a spiral manner.

[0040] In this embodiment, the left end cap 1 and the right end cap 21 are fixed on the valve body 37, and a first sealing ring 6 and a second sealing ring 17 are provided between them and the valve body 37 to prevent the entire valve oil from leaking.

[0041] In this embodiment, the valve body 37 is provided with an oil inlet 33, an oil outlet 29, a first working oil port 31, a second working oil port 35, and a curved flow channel 15. The oil inlet 33 on the valve body 37 is sealed with an eleventh sealing ring 32, the oil outlet 29 is sealed with a ninth sealing ring 28, the first working oil port 31 is sealed with a tenth sealing ring 30, and the second working oil port 35 is sealed with a twelfth sealing ring 34.

[0042] In this embodiment, when the valve sleeve 8 and the valve core 10 move left and right, when the groove of the valve sleeve 8 and the protrusion of the valve core 10 are fully engaged, no oil enters the curved oil passage 15 of the valve body 37. When the groove of the valve sleeve 8 and the protrusion of the valve core 10 are engaged on the right side, the oil inlet 33 is connected to the first working oil port 31, and the second working oil port 35 is connected to the oil outlet 29 through the curved flow channel 15. When the groove of the valve sleeve 8 and the protrusion of the valve core 10 are engaged on the left side, the oil inlet 33 is connected to the second working oil port 35, and the first working oil port 31 is connected to the oil outlet 29 through the curved flow channel 15.

[0043] It should be noted that a complete fit means that the protrusion of the valve core 10 completely blocks the oil hole on the groove of the valve sleeve 8. A right-side fit means that the protrusion of the valve core 10 is located on the right side of the groove of the valve sleeve 8, and the oil hole on the groove of the valve sleeve 8 is not completely blocked. A left-side fit means that the protrusion of the valve core 10 is located on the left side of the groove of the valve sleeve 8, and the oil hole on the groove of the valve sleeve 8 is not completely blocked.

[0044] In this embodiment, the entire valve is controlled by a combination of a motor and an electromagnet, which combines the rapid response of the electromagnet with the precise positioning of the motor to achieve high-precision control of flow and pressure.

[0045] The principle and process of using this invention alone are as follows:

[0046] like Figure 1 As shown, when electrode 23 in the motor is not energized, rotor 24 does not drive rotating connecting plate 27 to rotate, coil 19 in electromagnet is also not energized, armature 41 is in contact with the top of fixed iron core 42, spring 39 is in normal unforced state, and electromagnet is in normal position. The groove of valve sleeve 8 and the protrusion of valve core 10 are fully engaged, and no oil enters valve body 37.

[0047] like Figure 2As shown, when electrode 23 in the motor is energized, rotor 24 drives rotating connecting plate 27 to rotate. Rotating connecting plate 27 has a rotating connecting plate protruding ball 27a that cooperates with the inner guide rail 7 of the valve sleeve. Valve sleeve 8 has a valve sleeve limiting block 44, causing valve sleeve 8 to translate towards the electromagnet. Coil 19 in the electromagnet is also energized. Because the valve core guide rail 10a at the end of valve core 10 cooperates with the rotating connecting plate slide rail 27c on rotating connecting plate 27, armature 41 drives valve core 10 to spirally translate towards the motor. The rotation of valve core 10 causes valve core connector 16 to rotate and translate along the annular track of outer guide rail 43 of valve sleeve. At this time, spring 39 is in a compressed state, and electromagnet is in the working position. The groove of the valve sleeve 8 engages with the left side of the valve core protrusion 10b of the valve core 10, allowing oil to enter the valve body 37. At this time, the oil inlet 33 is connected to the first working oil port 31, and the second working oil port 35 is connected to the oil outlet 29 through the curved flow channel 15.

[0048] like Figure 3 As shown, when electrode 23 in the motor is energized, rotor 24 drives rotating connecting plate 27 to rotate. Rotating connecting plate 27 has a rotating connecting plate protrusion sphere 27a that cooperates with the inner guide rail 7 of the valve sleeve. Valve sleeve 8 has a valve sleeve limiting block 44, causing valve sleeve 8 to translate towards the motor direction. Coil 19 in the electromagnet is also energized. Due to the cooperation between valve core guide rail 10a at the end of valve core 10 and rotating connecting plate slide rail 27c on rotating connecting plate 27, and the combined action of spring 39 and rotor 24, armature 41 drives valve core 10 to spirally translate towards the electromagnet. At this time, spring 39 is in a state of gradual elastic recovery, and the electromagnet is in the working position. The groove of valve sleeve 8 cooperates with the right side of valve core protrusion 10b of valve core 10, allowing oil to enter valve body 37. At this time, oil inlet 33 connects with the second working oil port 35, and the first working oil port 31 connects with oil outlet 29 through curved flow channel 15.

[0049] like Figure 4-5 As shown, when electrode 23 in the motor is energized, rotor 24 drives rotating connecting plate 27 to rotate. Rotating connecting plate 27 has a rotating connecting plate protrusion spherical 27a that cooperates with the inner guide rail 7 of the valve sleeve, causing valve sleeve 8 to translate towards the electromagnet. Coil 19 in the electromagnet is also energized. Because the valve core guide rail 10a at the end of valve core 10 cooperates with the rotating connecting plate slide rail 27c on rotating connecting plate 27, armature 41 drives valve core 10 to spirally translate towards the motor. At this time, spring 39 is in a compressed state, and electromagnet is in the working position. The groove of valve sleeve 8 and the valve core protrusion 10b of valve core 10 are fully engaged, preventing oil from entering valve body 37.

[0050] In this embodiment, the helical translation of the valve core and the linear translation of the valve sleeve are precisely controlled by the coordinated drive of the motor and electromagnet to adjust the oil flow path and flow rate. The motor drives the rotating connecting plate to move the valve sleeve, and the electromagnet drives the armature to make the valve core move helically along the guide rail. The two work together to change the connection state of the inlet and outlet ports, realizing precise regulation of flow rate and directional control. The cooperation between the valve core and the valve sleeve effectively blocks or opens the oil circuit, thereby achieving high-precision control of the flow rate and pressure of the hydraulic system.

[0051] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
