This type of hydraulic pilot control valve has a complex structure, a large number of parts, difficult processing, high cost, and is not easy to assemble. There is also a risk of oil leakage. Summary of the invention

[0005] By cooperating with the follower elastic component and the detection module, the dynamics of the control member are obtained and converted into a displacement electrical signal output of the follower elastic component. The drive device is triggered to act according to the displacement electrical signal. When the signal generating device is used to control the operation of the hydraulic valve, the electrical signal generated by the signal generating device can play a pilot control role on the hydraulic valve. Compared with the pilot hydraulic valve in the prior art, the signal generating device of the present invention does not need to adopt a valve body structure, has a simple structure, does not need to use oil, and does not have the risk of oil leakage. In addition, the electronic control method has a faster response speed than the pilot hydraulic valve and is more sensitive to control.
[0006] Furthermore, the follow-up elastic components are an even number group, and at least one of the two groups of follow-up elastic components arranged opposite to each other is provided with a detection module.
[0007] Furthermore, the follower elastic component includes a push rod and an elastic member, the push rod acts on the control member under the action of the elastic member, and the detection module obtains the linear displacement of the push rod and converts it into a displacement electrical signal for output.
[0008] Furthermore, the movement range of the push rod of the follower elastic component provided with the detection module is greater than the movement range of other push rods.
[0009] Furthermore, the axial length of the stroke hole I where the elastic part of the follower elastic component of the detection module is located is greater than the axial length of the stroke hole I where other elastic parts are located; or, a reset part is provided between the top rod and the elastic part of the follower elastic component of the detection module, and under the action of the reset part, the top rod can move axially relative to the elastic part.
[0010] Furthermore, the detection module includes a displacement element and a sensing element, the sensing element is fixedly assembled, and the displacement element moves linearly with the ejector rod.
[0011] Further, in the initial state, all the elastic members are in the same compression state, and all the reset members are in the same compression state.
[0012] Furthermore, the control member is mounted on the carrier via a universal joint, and an actuating portion is formed on the control member, and the actuating portion of the control member is used to drive the follower elastic component to perform linear motion.
[0013] A remote control device comprises: a signal generating device; and a controller, wherein the controller receives a displacement electrical signal output by the signal generating device and converts the displacement electrical signal into a control signal.
[0014] Furthermore, the controller transmits the control signal to the driving device via wired or wireless transmission.
[0015] Based on the above technical solution, the technical effects that can be achieved by the present invention are:
[0016] 1. The signal generating device of the present invention obtains the dynamics of the control member and converts it into a displacement electric signal output of the follower elastic component through the cooperation of the follower elastic component and the detection module, and triggers the action of the driving device according to the displacement electric signal. When the signal generating device is used to control the operation of the hydraulic valve, the electric signal generated by the signal generating device can play a pilot control role on the hydraulic valve. Compared with the pilot hydraulic valve in the prior art, the signal generating device of the present invention does not need to adopt a valve body structure, has a simple structure, does not need to use oil, and does not have the risk of oil leakage; in addition, the electronic control method has a faster response speed than the pilot hydraulic valve and is more sensitive to control;
[0017] 2. The signal generating device of the present invention is provided with at least 4 groups of follow-up elastic components, which extend vertically and are evenly arranged around the outer periphery of the operating member, so that the operating member will always press downward at least one group of follow-up elastic components when it deflects in any direction, and the signal generating device can obtain a displacement electrical signal corresponding to any deflection position of the operating member, with high control accuracy; further, the follow-up elastic components are provided in 4 groups, which are respectively located in four directions, so that displacement electrical signals in four directions can be obtained, which is convenient for signal conversion;
[0018] 3. The signal generating device of the present invention, by setting uniformly distributed follow-up elastic components, enables the control member to always maintain a vertical state in the initial state, and the control accuracy is high; by setting a detection module on at least one of the two relatively groups of follow-up elastic components, the movement range of the top rod of the follow-up elastic component provided with the detection module is greater than the movement range of other top rods, so that the use of detection modules can be reduced, and the linear displacement of the top rods in the two relatively groups of follow-up elastic components can be reflected by one detection module. In this way, the four groups of follow-up elastic components only need two detection modules to accurately obtain the displacement electrical signal; the top rod of the follow-up elastic component provided with the detection module can be raised and lowered relative to the initial state, and the movement of the two relatively arranged groups of follow-up elastic components can be accurately measured, and the follow-up elastic component without the detection module can cooperate to play the role of resetting the control member; further, by reasonably setting the axial length of the stroke hole I or setting the top rod to be movable relative to the spring seat, the effect of increasing the movement range of the top rod of the follow-up elastic component provided with the detection module can be achieved;
[0019] 4. The signal generating device of the present invention sets the control member in the initial state, all elastic members are in the same compression state, all reset members are in the same compression state, and there is a certain pre-tightening force, which can bring an ergonomic operation feeling to the operator; compared with the prior art using a pilot hydraulic valve, when the control member is reset, the reset component not only needs to overcome the gravity of the control member, but also overcome the oil pressure, and is prone to damage and failure after long-term operation; the reset component of the present application does not need to overcome the oil pressure and has a long service life;
[0020] 5. The remote control device of the present invention converts the deflection movement of the operating member into a displacement electrical signal output through a signal generating device, and the controller further converts the displacement electrical signal into a control signal to control the operation of the driving device. The driving device can drive various devices including hydraulic valves to work.

[0032] Embodiment 1
[0033] like Figure 1-2 As shown, this embodiment provides a signal generating device, including a carrier 1, an operating member 2, a follower elastic component 4 and a detection module 5. The operating member 2 is universally mounted on the carrier 1. The operating member 2 deflects and presses the follower elastic component 4. The follower elastic component 4 is provided with a detection module 5 for detecting the linear displacement of the follower elastic component 4 and converting it into a displacement electrical signal output.
[0034] The control member 2 is mounted on the carrier 1 through a universal joint 3. Specifically, one end of the universal joint 3 is fixedly connected to the carrier 1, and the other end of the universal joint 3 is fixedly connected to the control member 2. In this embodiment, both ends of the universal joint 3 are provided with external threads, one end of the universal joint 3 extends into the carrier 1 and is threadedly connected to the carrier 1, and the other end of the universal joint 3 extends into the control member 2 and is threadedly connected to the control member 2.
[0035] In order to facilitate the deflection of the operating member 2 to press the follower elastic component 4, an actuating portion 21 can be set on the periphery of the operating member 2 or on the periphery of one end of the universal joint 3 fixedly connected to the operating member 2. The pressure piece 21 can be annular or discrete, as long as it can ensure that all the follower elastic components 4 are equally against the pressure piece 21.
[0036] There are at least 4 groups of follower elastic components 4, which extend vertically and are evenly arranged around the periphery of the control member 2. When the control member 2 drives the actuating portion 21 to deflect, at least one group of follower elastic components 4 can be pressed downward. In this embodiment, there are 4 groups of follower elastic components 4, which are evenly distributed around the periphery of the control member 2 and are respectively located in four directions centered on the axis of the control member 2.
[0037] The follow-up elastic component 4 is telescopically arranged on the carrier 1. Specifically, the follow-up elastic component 4 includes an elastic member 41 and a push rod 42. The carrier 1 has a vertically connected stroke hole I11 and a stroke hole II12. The elastic member 41 is placed in the stroke hole I11, and the push rod 42 is placed in the stroke hole II12. One end of the elastic member 41 abuts against the bottom of the stroke hole I11, and the other end acts on the push rod 42. The end of the push rod 42 away from the elastic member 41 extends out of the stroke hole II12 and abuts on the actuating portion 21. The elastic member 41 cooperates with the push rod 42 through a spring seat 43. Specifically, the spring seat 43 is located in the stroke hole I11, and the spring seat 43 can slide along the stroke hole I11. The elastic member 41 abuts against one end of the spring seat 43, and the push rod 42 is fixedly connected to the other end of the spring seat 43. In this embodiment, the push rod 42 is fixedly plugged into the spring seat 43, a plug hole is opened in the middle of the spring seat 43, and an insertion portion is extended from the end of the push rod 42, and the fixed connection between the two is achieved by interference fit between the insertion portion and the plug hole or by a connector or threaded connection. Preferably, the travel hole I11 is a stepped hole, and the outer diameter of the spring seat 43 is further set to be larger than the outer diameter of the elastic member 41 to limit the range of motion of the spring seat 43. The aperture of the travel hole I11 is larger than the aperture of the travel hole II12, so that the push rod 42 can extend into the travel hole I11 to compress the elastic member 41, but the spring seat 43 and the elastic member 41 cannot extend into the travel hole II12, thereby achieving a limiting effect and ensuring the stability of the operation of the follower elastic component 4. The elastic member 41 is optional but not limited to a spring.
[0038] At least four groups of follow-up elastic components 4 are arranged opposite to each other in pairs, and at least one of the two groups of follow-up elastic components 4 arranged opposite to each other is provided with a detection module 5 to detect the linear displacement of the follow-up elastic component 4 and / or the opposite follow-up elastic component 4 and convert it into a displacement electrical signal for output. In this embodiment, among the four groups of follow-up elastic components 4, only one of the two groups of follow-up elastic components 4 arranged opposite to each other is provided with a detection module 5, that is, only two detection modules 5 are provided for the four groups of follow-up elastic components 4 to obtain the linear displacement of the four groups of follow-up elastic components 4.
[0039] The detection module 5 includes a displacement element 51 and a sensing element 52. The sensing element 52 is built into the carrier 1. One end of the displacement element 51 is fixedly connected to the push rod 42, and the other end of the displacement element 51 extends between the two sensing elements 52. The push rod 42 drives the displacement element 51 to move linearly in the sensing element 52. The sensing element 52 obtains the displacement of the displacement element 51 and converts it into a displacement electrical signal. Preferably, a mounting cavity 13 connected to the end of the stroke hole I11 away from the stroke hole II is provided in the carrier 1, and the sensing element 52 is placed in the mounting cavity 13. In this embodiment, the sensing element 52 can be two coils, and the displacement element 51 can be a magnetic rod, as long as the displacement electrical signal can be obtained. The electrical signal obtained by the sensing element 52 is transmitted through the cable 53. The detection module 5 can be selected from but not limited to the Honeywell SR3C-A1 displacement sensor.
[0040] The deflection of the control member 2 will cause the linear motion of the push rod 42, and the relationship between the two can be described by the following formula:
[0041] L=(D / 2)*(α / 180)*π
[0042] Wherein, L is the linear displacement length of the push rod 42, D is the distance between two opposite push rods 42, and α is the rotation angle of the control member 2 around the center of the universal joint 3, in degrees.
[0043] Preferably, the range of motion of the push rod 42 of the follower elastic component 4 provided with the detection module 5 is greater than the range of motion of the push rod 42 of the follower elastic component 4 not provided with the detection module 5. The follower elastic component 4 provided with the detection module 5 can be raised and lowered relative to the initial position to measure the linear upward displacement and the linear downward displacement. In this way, only one set of the two sets of follower elastic components 4 provided relatively can be provided with the detection module 5. Since the expansion and contraction conditions of the two sets of follower elastic components 4 provided relatively are opposite, the linear displacement of the two sets of follower components 4 provided relatively can be reflected by one detection module 5. In this embodiment, the range of motion of the push rod 42 is changed by changing the axial length of the stroke hole I11. Specifically, the axial length of the stroke hole I11 where the elastic member 41 of the follower elastic component 4 provided with the detection module 5 is greater than the length of other stroke holes I11. Specifically, the bottom end heights of all the stroke holes I11 are the same, and the top end of the stroke hole I11 where the elastic member 41 of the follower elastic component 4 provided with the detection module 5 is higher than the top end of other stroke holes I11. That is, the top rod 42 of the follower elastic assembly 4 without the detection module 5 can only move to the initial state at most, while the top rod 42 of the follower elastic assembly 4 with the detection module 5 can be raised and lowered relative to the initial state. Preferably, in the initial state, the operating member 2 remains in a vertical state, and all the elastic members 41 are in the same compression state.
[0044] Preferably, the carrier 1 can be integrally formed or separately provided. For the convenience of installation, in the present embodiment, the carrier 1 is separately provided, and the inner diameter change of the self-travel hole I11 of the carrier 1 is divided into two parts, so that the follower elastic component 4 can be easily installed in the carrier 1.
[0045] This embodiment also provides a remote control device, including the above-mentioned signal generating device, and also including a controller 6, the controller 6 is connected to the sensing element 52 through a cable 53, the signal generating device outputs a displacement electrical signal which can be transmitted to the controller 6, the controller 6 receives the above-mentioned displacement electrical signal and converts it into a control signal, and transmits the control signal to the drive device 8, and the drive device 8 works according to the control signal. The drive device 8 can be an electric drive device or an electro-hydraulic drive device, and the drive device 8 includes but is not limited to a proportional electromagnet and a servo motor. Preferably, the controller 6 can be built into the carrier 1, or can be set separately from the carrier 1.
[0046] The control signal may be an analog signal or a PWM signal. The controller 6 and the drive device 8 may be connected via a wiring harness 7 to achieve wired control. Specifically, the analog signal or the PWM signal is converted by the controller 6 and then output to the drive device 8 via the wiring harness 7 using the CAN protocol or other protocols. Wireless control may also be used between the controller 6 and the drive device 8. Specifically, a transmitter electrically connected to the controller 6 is provided to transmit the control signal to a receiver, and the receiver is electrically connected to the drive device 8. The control signal is converted into a CAN protocol via a CAN module. Preferably, a CAN module of model USBcan Pro 2xHSv2 CB produced by Kvaser may be used.
[0047] The driving device 8 can drive various devices including hydraulic valves to work. Taking the driving of a hydraulic valve as an example, the hydraulic valve includes a valve body and a valve core. The valve core is slidably arranged in the valve body. The valve body is provided with multiple oil ports. The driving device 8 drives the valve core to slide in the valve body. There are many ways for the driving device 8 to drive the valve core to slide. The driving device 8 can drive the valve core to perform linear reciprocating motion in the valve body through a linear module. The linear module can be selected but not limited to a gear rack structure. For example, the driving device drives the gear to rotate, the gear rack is meshed, and the rack drives the valve core to perform linear reciprocating motion.
[0048] Taking the operation of the remote-controlled hydraulic valve as an example, the working principle of the remote control device of the present invention is: the operator operates the control member 2, the control member 2 rotates around the universal joint 3, the actuating portion 21 of the control member 2 presses down at least one follower elastic component 4, and the detection module on the follower elastic component 4 obtains the linear displacement and converts it into a displacement electrical signal output. The controller 6 receives the displacement electrical signals in various directions and converts them into control signals to control the operation of the drive device 8. The drive device 8 drives the valve core to slide in the valve body through the linear module.
[0049] Embodiment 2
[0050] like Figure 3-4 As shown, this embodiment is basically the same as the first embodiment, and the only difference is that the structure of the follower elastic component 4 provided with the detection module 5 and the arrangement of the travel hole I11 are different.
[0051] In this embodiment, the axial position and axial length of all the travel holes I11 are the same, and the range of motion of the push rod 42 of the follower elastic component 4 provided with the detection module 5 is increased by changing the connection relationship between the push rod 42 and the spring seat 43. Specifically, for the structure of the follower elastic component 4 provided with the detection module 5, there is no need for a fixed connection between the push rod 42 and the spring seat 43, and one end of the push rod 42 inserted into the spring seat 43 is provided with a receiving hole, and a reset member 44 is built into the receiving hole, and one end of the reset member 44 acts on the spring seat 43, and the other end acts on the push rod 42, that is, the push rod 42 can also rise relative to the spring seat 43 under the action of the reset member 44, thereby increasing the range of motion of the push rod 42. The structure of the follower elastic component 4 without the detection module is the same as that of the first embodiment. The reset member 44 is optional but not limited to a spring.
[0052] Furthermore, the displacement element 51 is pressed against the push rod 42 by the reset member 44, and a limit block 511 is provided at one end of the displacement element 51 away from the sensing element 52. One end of the reset member 44 acts on the spring seat 43, and the other end acts on the limit block 511, pressing the limit block 511 against the push rod 42.
[0053] Preferably, in the initial state, the operating member 2 maintains a vertical state, all elastic members 41 are in an equally compressed state, and all reset members 44 are in an equally compressed state.
[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
