Description

Technical Field

[0001] This utility model relates to the field of joystick technology, and in particular to a dual-axis electronically controlled joystick. Background Technology

[0002] In special-purpose vehicles and other equipment, operators need to control the movement of robotic arms using joysticks to complete various complex actions. Traditional joysticks use potentiometers and mechanical positioning to detect the joystick angle, but these methods have drawbacks such as easy wear and low accuracy.

[0003] To improve the detection accuracy of joysticks, existing joysticks use Hall effect sensors to detect their angle. The Hall effect of the sensor allows for precise detection of changes in the magnetic field, thus converting the joystick's angular displacement into an electrical signal.

[0004] For dual-axis joysticks, the Hall sensor needs to detect the angle in two directions, which can easily cause signal interference in the two directions and reduce the accuracy of angle detection. Utility Model Content

[0005] The purpose of this invention is to provide a dual-axis electronic joystick that can avoid signal interference from two directions detected by a Hall sensor.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A dual-axis electric joystick is provided, comprising:

[0008] Support components;

[0009] A control lever, which is rotatably connected to the support assembly;

[0010] Two magnetic encoders, one of which has a central axis extending along a first direction and the other has a central axis extending along a second direction. Both magnetic encoders are rotatable about their respective central axes, and the control lever is capable of driving the two magnetic encoders to rotate.

[0011] A first Hall sensor and a second Hall sensor are mounted on the support assembly, and the first Hall sensor and the second Hall sensor each correspond to one of the magnetic code disks;

[0014] Optionally, the first limiting member is provided with a first sliding groove extending along the first direction, and the second limiting member is provided with a second sliding groove extending along the second direction. The control rod is located in the first sliding groove and the second sliding groove and is in contact with the inner wall of the first sliding groove and the second sliding groove.

[0015] Optionally, one end of the first limiting member is fixedly connected to the corresponding magnetic code disk, and the other end of the first limiting member is rotatably connected to the support assembly; one end of the second limiting member is fixedly connected to the corresponding magnetic code disk, and the other end of the second limiting member is rotatably connected to the support assembly.

[0022] The beneficial effects of this utility model are:

[0023] This invention provides a dual-axis electrically controlled joystick, including a support assembly, a control lever, two magnetic encoders, a first Hall sensor, a second Hall sensor, and a reset assembly. The control lever is rotatably connected to the support assembly. The central axis of one magnetic encoder extends along a first direction, and the central axis of the other magnetic encoder extends along a second direction. Both magnetic encoders can rotate around their respective central axes, and the control lever can drive the two magnetic encoders to rotate. The first and second Hall sensors are mounted on the support assembly, and each corresponds to a magnetic encoder. Rotation of the control lever drives the magnetic encoders to rotate. The first and second Hall sensors can detect the rotation angle of their corresponding magnetic encoders, thus obtaining the rotation angle of the control lever along the first and second directions. Since the two magnetic encoders rotate in different directions, both the first and second Hall sensors only detect the rotation angle of the control lever within one plane. The first and second Hall sensors can independently process signals in their respective directions, avoiding signal interference and improving the accuracy of angle detection. The reset assembly is mounted on the support assembly and can drive the control lever back to the neutral position. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "front," "rear," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] likeFigures 1-5 As shown, this embodiment provides a dual-axis electrically controlled joystick, including a support assembly 1, a control lever 2, two magnetic encoder disks 3, a first Hall sensor 41, a second Hall sensor 42, and a reset assembly 5. The control lever 2 is rotatably connected to the support assembly 1. The central axis of one magnetic encoder disk 3 extends along a first direction, and the central axis of the other magnetic encoder disk 3 extends along a second direction. Both magnetic encoder disks 3 can rotate around their respective central axes, and the control lever 2 can drive the two magnetic encoder disks 3 to rotate. The first Hall sensor 41 and the second Hall sensor 42 are mounted on the support assembly 1, and each corresponds to one magnetic encoder disk 3. Rotation of the control lever 2 drives the magnetic encoder disks 3 to rotate. The first Hall sensor 41 and the second Hall sensor 42 can detect the angle of rotation of their corresponding magnetic encoder disks 3, thereby obtaining the angle of rotation of the control lever 2 along the first and second directions. Since the two magnetic encoders 3 rotate in different directions, both the first Hall sensor 41 and the second Hall sensor 42 only detect the angle of rotation of the control lever 2 within one plane. The first Hall sensor 41 and the second Hall sensor 42 can process the signals in their respective directions independently, avoiding signal interference and improving the accuracy of angle detection. The reset assembly 5 is mounted on the support assembly 1 and can drive the control lever 2 back to the neutral position.

[0042] Specifically, the first direction is Figure 3 The X direction in the middle, the second direction is Figure 3 The Y-direction, the first direction, and the second direction are two mutually perpendicular directions in the horizontal plane. The support assembly 1 includes a support plate 11, a base 12, and a housing 13. The support plate 11 is annular, and the base 12 is connected to the lower part of the support plate 11 by screws. The control lever 2 passes through the inner ring of the support plate 11 from above and is connected to the base 12. (See reference...) Figure 1 and Figure 6The control lever 2 is available in left-hand and right-hand versions. The left-hand version tilts to the right at the end furthest from the support plate 11, while the right-hand version tilts to the left at the end furthest from the support plate 11, allowing the user to select the appropriate type of control lever 2. Four mounting seats 111 are located above the support plate 11, all mounted on its edge. Two of these seats are positioned opposite each other along a first direction and have mounting holes extending along that direction. The other two seats are positioned opposite each other along a second direction and also have mounting holes extending along that direction. Two magnetic encoder disks 3 are respectively mounted in adjacent mounting holes and can rotate relative to the inner wall of the holes. A first Hall sensor 41 and a second Hall sensor 42 each correspond to a magnetic encoder disk 3 and are mounted in the mounting holes. The first Hall sensor 41 and the second Hall sensor 42 are located on the side of their corresponding magnetic encoder disks 3 facing away from the control lever 2. A reset assembly 5 is mounted on the base 12. The outer casing 13 is fitted over the base 12 to prevent external dust from contaminating the base 12 and the reset assembly 5.

[0043] Optionally, such as Figure 1 and Figure 2 As shown, the dual-axis electric control joystick also includes a universal joint 8. One end of the universal joint 8 is connected to the support assembly 1, and the other end is connected to the control lever 2. The control lever 2 is connected to the support assembly 1 through the universal joint 8, which has good stability.

[0044] Specifically, one end of the universal joint 8 is connected to the center of the base 12 by a screw, and the other end is connected to the bottom of the control lever 2 by a screw. In other embodiments, a hemispherical hole can be provided on the base 12, and a ball can be provided at the bottom of the control lever 2, with the ball rotatably connected to the hemispherical hole.

[0045] Optionally, such as Figures 1-5 As shown, the dual-axis electric control joystick also includes a first limiting member 61 and a second limiting member 62. The first limiting member 61 and the second limiting member 62 are respectively fixedly connected to a magnetic encoder 3. The control lever 2 can drive the first limiting member 61 and the second limiting member 62 to rotate. The rotation of the first limiting member 61 and the second limiting member 62 can drive the two magnetic encoders 3 to rotate respectively. Thus, the first Hall sensor 41 and the second Hall sensor 42 measure the rotation angle of the two magnetic encoders 3 respectively, and thus obtain the angle change of the control lever 2 in the first direction and the second direction.

[0046] Furthermore, the first limiting member 61 is provided with a first sliding groove extending along a first direction, and the second limiting member 62 is provided with a second sliding groove extending along a second direction. The control rod 2 is located within the first and second sliding grooves and is in contact with the inner walls of the first and second sliding grooves. Rotation of the control rod 2 within the first sliding groove can drive the second limiting member 62 to rotate, which in turn drives the magnetic encoder 3 connected to it to rotate. The rotation angle of the corresponding magnetic encoder 3 is measured by the second Hall sensor 42. Similarly, rotation of the control rod 2 within the second sliding groove can drive the first limiting member 61 to rotate, which in turn drives the magnetic encoder 3 connected to it to rotate. The rotation angle of the corresponding magnetic encoder 3 is measured by the first Hall sensor 41.

[0047] Specifically, both the first limiting member 61 and the second limiting member 62 are elongated. The first limiting member 61 extends along a first direction, and the second limiting member 62 extends along a second direction, intersecting each other. The first sliding groove and the second sliding groove also intersect each other, and the control rod 2 passes through the intersection of the first and second sliding grooves. The width of the first and second sliding grooves is the same as the diameter of the control rod 2.

[0048] Optionally, one end of the first limiting member 61 is fixedly connected to the corresponding magnetic code disk 3, and the other end of the first limiting member 61 is rotatably connected to the support component 1; one end of the second limiting member 62 is fixedly connected to the corresponding magnetic code disk 3, and the other end of the second limiting member 62 is rotatably connected to the support component 1, thereby improving the connection stability of the first limiting member 61 and the second limiting member 62.

[0049] Specifically, the ends of the first limiting member 61 and the second limiting member 62 connected to the magnetic code disk 3 are each provided with a square positioning groove. The magnetic code disk 3 is provided with a first protrusion with a square cross-section, which extends into the corresponding positioning groove and is interference-fitted with the inner wall of the positioning groove. The other ends of the first limiting member 61 and the second limiting member 62 are each provided with a second protrusion with a circular cross-section. The second protrusion corresponds one-to-one with the mounting holes where the magnetic code disk 3 is not installed and extends into the mounting holes, and can rotate relative to the inner wall of the mounting holes.

[0050] Optionally, the surfaces of the first limiting member 61 and the second limiting member 62 are both partially spherical, giving them higher structural strength, improving their stability, and preventing interference during rotation. Specifically, both the first limiting member 61 and the second limiting member 62 protrude upwards, and their centers are the same.

[0051] Optionally, the dual-axis electric joystick also includes a circuit board mounted on the support assembly 1. The first Hall sensor 41 and the second Hall sensor 42 are communicatively connected to the circuit board, and the circuit board transmits the data of the first Hall sensor 41 and the second Hall sensor 42 to an external device so that the detection results of the first Hall sensor 41 and the second Hall sensor 42 can be obtained.

[0052] Specifically, the support assembly 1 also includes a mounting box 14, which is connected to the end of the base 12 away from the support plate 11 by screws. A circuit board is mounted inside the mounting box 14, and the first Hall sensor 41 and the second Hall sensor 42 are connected to the circuit board via wires. The circuit board, the first Hall sensor 41, and the second Hall sensor 42 are all sealed with potting compound to provide dust and water protection.

[0053] Optionally, a PWM adjustment device is provided on the circuit board. The output signal of the PWM adjustment device has strong anti-interference capability and improves the accuracy of the signal output. Specifically, the PWM adjustment device is equipped with an anti-accidental touch function, and the anti-accidental touch angle range of the PWM adjustment device is ±5°. When the rotation angle of the control lever 2 in the first direction or the second direction is within the range of -5° to 5°, the PWM adjustment device does not output a signal; when the rotation angle of the control lever 2 in the first direction or the second direction is outside the range of -5° to 5°, the PWM adjustment device outputs a signal.

[0054] Optionally, the dual-axis electric joystick also includes a handle assembly 7, which is connected to the control lever 2. The handle assembly 7 is provided with a button 71, which is electrically connected to the circuit board for easy user operation.

[0055] Specifically, the handle assembly 7 includes a gear lever 72 and a connecting rod 73. One end of the connecting rod 73 is connected to the control lever 2 by a screw, and the other end is connected to the gear lever 72 by a screw. A button 71 is mounted on the top of the gear lever 72. The gear lever 72 is covered with soft rubber to improve the user's comfort when turning the gear lever 72.

[0056] Furthermore, the dual-axis electric control joystick also includes a dustproof soft cover 9, which is positioned above the support plate 11, and the end of the dustproof soft cover 9 facing the support plate 11 is sealed to the edge of the support plate 11. The end of the dustproof soft cover 9 away from the support plate 11 is sealed to a soft rubber seal, serving to prevent water and dust.

[0057] Optionally, the reset assembly 5 includes a pusher 51 and an elastic member 52. One end of the elastic member 52 is connected to the support assembly 1, and the other end is connected to the pusher 51. The pusher 51 can abut against the control lever 2 to drive the control lever 2 back to the center position.

[0058] Specifically, four reset components 5 are provided, each corresponding to a mounting base 111. The base 12 has four mounting slots, with each elastic element 52 corresponding to a mounting slot. One end of the elastic element 52 is connected to the bottom of the mounting slot, and the other end extends upward and abuts against the pushing element 51. The reset component 5 also includes a base 53 and a reset sleeve 54. The base 53 is positioned between the pushing element 51 and the elastic element 52. Grooves are provided on both opposite sides of the base 53, and the pushing element 51 and the elastic element 52 abut against different grooves, improving the stability of their contact. The reset sleeve 54 is interference-fitted onto the outer wall of the universal joint 8 near the control lever 2. An abutment edge is provided at the bottom of the reset sleeve 54. The end of the pushing element 51 away from the elastic element 52 abuts against the abutment edge. The pushing element 51 is a ball-head plunger, and the elastic element 52 is a spring. The user applies force to rotate the control lever 2, causing it to tilt in one direction. The abutment edge presses against the pusher 51 in that direction, causing the pusher 51 to move downwards. The pusher 51 then compresses the elastic element 52. After the user removes the force applied to the control lever 2, the elastic element 52 returns to its original shape, pushing the pusher 51 upwards. The pusher 51 then pushes against the abutment edge, resetting the control lever 2 connected to the reset sleeve 54. Simultaneously, the reset assembly 5 also limits the rotation angle of the control lever 2, preventing it from rotating too far.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
