Description

Technical Field

[0001] This invention relates to the field of flight simulator technology, specifically to a flight simulator joystick. Background Technology

[0002] HOTAS (Hans On Throttle And Stick) flight simulator joystick: A concept widely used in modern fighter jets. Translated as "Hands On Throttle And Stick" or "Dual-stick control system," it integrates cockpit system operations onto buttons on a throttle and a stick, allowing pilots to operate various cockpit systems without taking their hands off the stick. The HOTAS flight simulator joystick is a peripheral product designed to simulate the experience of real fighter jets, meeting users' needs for flight simulation experiences.

[0003] The main structure of the HOTAS Throttle valve is a push rod that moves back and forth. During the movement of the push rod, it is inevitable that the equipment housing needs to have a slot for its movement. In order to improve the dustproof level and electromagnetic protection of the product, the slot needs to be dustproofed.

[0004] Similar products on the market generally use methods such as reducing the groove opening and adding brushes to treat dust; these methods will result in disadvantages such as poor dustproof effect, increased resistance to push rod movement, and excessive space occupied by the dustproof structure that cannot be arranged.

[0005] Hotas Throttle Actuator System: The main structure of this system consists of left and right actuators and their respective supported linear motion modules. Hotas Throttle Actuator Force Adjustment Structure: The movement of the left and right actuators in the Hotas Throttle Actuator System requires a certain degree of damping to simulate real aircraft operation. The required damping force varies depending on the user and aircraft type; therefore, the Hotas Throttle Actuator System needs a structure to adjust the actuator damping force.

[0006] Split-type control handle: The HOTAS throttle valve split-type control handle has a left and right push rod structure to control the throttle opening of various aircraft models with dual or multiple engines in flight simulation. The split-type control handle needs to have technical characteristics such as accurate detection of push rod movement simulation amount, the need for the left and right push rods to be combined and separated into two states, and linear feedback force. However, the existing split-type control handle is not convenient for quickly confirming the switching state of the left and right push rods when using it.

[0007] To address the aforementioned issues, an improved flight simulator joystick is now designed. Summary of the Invention

[0008] The purpose of this invention is to provide a joystick for a flight simulator to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

Lead screw guide blocks are rotatably connected to the two opposite threads of the bidirectional lead screw. Compression expansion blocks that expand under pressure are installed on the first mounting seats at both ends of the bidirectional lead screw. The lead screw guide blocks and the compression expansion blocks cooperate with each other. The sidewalls of the compression expansion blocks are tightly attached to the sidewalls of the pressure rod. The mounting housing is provided with a drive assembly for driving the worm gear and the bidirectional lead screw to rotate.

[0018] As a further embodiment of the present invention: the drive assembly includes a worm gear, which is rotatably connected to a first mounting base near the worm wheel. The worm gear and the worm wheel mesh with each other. A rotating shaft for driving the worm gear to rotate is installed at the center of the worm gear. An adjustment knob is rotatably connected to the side wall of the mounting housing opposite the end face of the rotating shaft. The adjustment knob and the rotating shaft are connected by a ratchet mechanism.

[0019] As a further embodiment of the present invention: the limiting mechanism includes a limiting cylinder, which is installed at the end of the slider away from the arc-shaped block. A limiting rod is slidably connected to the inner wall of the limiting cylinder. Second mounting seats for supporting the limiting rod are installed at both ends of the limiting rod. The second mounting seats are installed at the lower end of the mounting housing.

[0020] As a further embodiment of the present invention: the dustproof mechanism includes a dustproof belt, and mounting brackets are vertically mounted on the mounting housings at both ends of the slide groove. The mounting brackets are located on the side of the mounting housing away from the right push rod housing and the left push rod housing. Guide rollers are rotatably connected to the upper and lower ends of the mounting brackets. The dustproof belt is sleeved on the side wall of the guide rollers, and the upper end of the dustproof belt is tightly attached to the mounting housing at the lower end of the slide groove. The slider is mounted on the dustproof belt.

[0021] As a further embodiment of the present invention: the analog measurement mechanism includes a magnetic strip, which is obliquely installed at the lower end of the mounting housing between two slides. The magnetic strip is not parallel to the slides, and a Hall PCB that works in conjunction with the magnetic strip is installed on the side wall of the magnetic strip opposite to the slider.

[0022] As a further embodiment of the present invention: the push rod opening and closing mechanism includes a mounting plate, a pin hole is provided at the lower end of the side wall of the left push rod housing near the right push rod housing, a moving rod is slidably connected to the bottom of the right push rod housing, a handle for easy movement of the moving rod is installed at the end of the moving rod away from the left push rod housing through the side wall of the right push rod housing, a pin is installed at the end of the moving rod near the left push rod housing to cooperate with the pin hole, and the end of the pin away from the moving rod passes through the side wall of the right push rod housing and is inserted into the inside of the pin hole, and a detection component for detecting whether the pin is inserted into the pin hole is provided on the mounting plate.

[0023] As a further embodiment of the present invention: the detection component includes a connecting frame, the connecting frame is installed on the side wall of the moving rod near the mounting plate, a baffle is installed at one end of the connecting frame near the mounting plate, and an infrared pair tube that cooperates with the baffle is installed on the side of the mounting plate near the connecting frame, the baffle being disposed between the infrared pairs tubes.

[0024] As a further aspect of the present invention: a buffer pad for buffering the limiting cylinder is installed on the side wall of the limiting rod near the second mounting seat.

[0025] As a further aspect of the present invention, a linear bearing is installed on the inner wall of the limiting cylinder to facilitate movement along the side wall of the limiting rod.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This invention uses a bidirectional lead screw to drive a lead screw guide block to compress an expansion block, causing the expansion block to expand and push a pressure rod, thus changing the pressure between the pressure rod and the arc-shaped locking block. This changes the friction between the pressure rod and the arc-shaped locking block. When the push rod moves, it drives the slider and the arc-shaped locking block to move. The arc-shaped locking block moves along the side wall of the pressure rod, thereby adjusting the resistance of the push rod movement.

[0028] Meanwhile, the push rod has linear force under various damping forces, smooth start-up with low starting force, and structural life and strength meet the requirements of working conditions. It also provides clear tactile feedback when reaching the maximum and minimum values ​​of the adjustment range, making it easy for users to operate.

[0029] This invention installs an annular dustproof strip on the slider, with the upper end of the dustproof strip tightly attached to the lower end of the slide groove. When the slider moves, the dustproof strip can completely seal the slide groove to prevent dust, resulting in good dust prevention, small space occupation, and low pushing resistance, which can meet the strength and service life requirements of the working conditions.

[0030] The separation and reassembly of the right push rod housing and the left push rod housing are achieved by moving the pin rod into and out of the pin hole. The operation is simple. At the same time, the separation and reassembly of the right push rod housing and the left push rod housing can be detected by whether the infrared phototransistor signal is blocked by the baffle.

[0031] By combining Hall effect PCB and magnet, the movement of the push rod can be detected in analog form, resulting in accurate detection results and a long lifespan. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-8In this embodiment of the invention, the flight simulator joystick includes a mounting shell 1, an adjustment mechanism, a limiting mechanism, a dustproof mechanism, a push rod opening and closing mechanism, and an analog quantity measurement mechanism. The upper end of the mounting shell 1 has two parallel sliding grooves 30. A slider 10 is slidably connected to the inner wall of the sliding groove 30. The upper ends of the two sliders 10 are respectively equipped with a right push rod shell 21 and a left push rod shell 22.

[0043] First mounting bases 19 are installed on the mounting housings 1 at both ends of the slide groove 30. The first mounting bases 19 are located between the two slide grooves 30. Two placement holes 33 are opened at the end of the first mounting base 19 near the center of the mounting housing 1. A pressure rod 8 is placed inside the placement hole 33. The pressure rod 8 can move horizontally inside the placement hole 33. An arc-shaped locking block 3 that cooperates with the pressure rod 8 is installed on the side wall of the slider 10 near the pressure rod 8. The arc-shaped locking block 3 is fitted onto the side wall of the pressure rod 8.

[0044] The adjustment mechanism is located between the two pressure rods 8 and is used to move the pressure rods 8 to change the pressure between the pressure rods 8 and the arc-shaped locking block 3, thereby changing the friction between the pressure rods 8 and the arc-shaped locking block 3 and adjusting the moving resistance of the slider 10.

[0045] The limiting mechanism is located on the side of the slider 10 away from the first mounting base 19, and is used to limit the slider 10.

[0046] The dustproof mechanism is installed on the slide 30 to seal the slide 30, prevent dust from entering the interior of the mounting housing 1, and protect the electronic components inside the mounting housing 1.

[0047] The analog measurement mechanism is mounted on the slider 10 and is used to measure the analog quantity of the movement of the right push rod housing 21 and the left push rod housing 22.

[0048] The push rod separation and engagement mechanism is provided on the right push rod housing 21 and the left push rod housing 22, and is used to connect the right push rod housing 21 and the left push rod housing 22 together for movement, or to separate the right push rod housing 21 and the left push rod housing 22 for movement.

[0049] The adjusting mechanism includes a bidirectional lead screw 4, which is disposed between two first mounting seats 19. The bidirectional lead screw 4 is parallel to the pressure rod 8. Both ends of the bidirectional lead screw 4 are rotatably connected to the two first mounting seats 19 respectively. One end of the bidirectional lead screw 4 passes through the first mounting seat 19 and is equipped with a worm gear 17 for driving the bidirectional lead screw 4 to rotate. Lead screw guide blocks 5 are rotatably connected to the two opposite threads of the bidirectional lead screw 4. Compression expansion blocks 6 that expand under pressure are installed on the first mounting seats 19 at both ends of the bidirectional lead screw 4. The lead screw guide blocks 5 and the compression expansion blocks 6 cooperate with each other. The sidewall of the compression expansion blocks 6 is tightly attached to the sidewall of the pressure rod 8. The mounting housing 1 is provided with a drive assembly for driving the worm gear 17 and the bidirectional lead screw 4 to rotate.

[0050] The drive assembly includes a worm gear 18, which is rotatably connected to a first mounting base 19 near the worm wheel 17. The worm gear 18 meshes with the worm wheel 17. A rotating shaft 16 for driving the worm gear 18 to rotate is installed at the center of the worm gear 18. An adjustment knob 14 is rotatably connected to the side wall of the mounting housing 1 opposite the end face of the rotating shaft 16. The adjustment knob 14 and the rotating shaft 16 are connected by a ratchet mechanism 15.

[0051] In use, the operator rotates the adjustment knob 14, which drives the ratchet mechanism 15 to rotate. The ratchet mechanism 15 drives the rotating shaft 16 to rotate, which drives the worm gear 18 to rotate. The worm gear 18 drives the worm wheel 17 to rotate, and the worm wheel 17 drives the double-acting screw 4 to rotate. Under the action of the screw thread, the double-acting screw 4 drives the two screw guide blocks 5 to move, and the two screw guide blocks 5 move in opposite directions. The screw guide blocks 5 squeeze the compression expansion block 6, and the compression expansion block 6 expands under pressure. The compression expansion block 6 pushes the pressure rod 8 to move towards the arc-shaped locking block 3. The pressure rod 8 presses tightly against the arc-shaped locking block 3, changing the friction between the pressure rod 8 and the arc-shaped locking block 3, thereby changing the resistance of the movement of the right push rod housing 21, the left push rod housing 22 and the slider 10, and realizing the resistance adjustment of the right push rod housing 21 and the left push rod housing 22.

[0052] When the maximum adjustment range is reached, the ratchet mechanism 15 jumps, allowing the user to feel that the force adjustment has reached its limit, thus avoiding damage to the mechanism due to over-adjustment.

[0053] When the adjustment range is reached to its minimum, the trigger screw mechanism locks, allowing the user to feel that the force adjustment has reached its limit, thus avoiding unnecessary free travel adjustment.

[0054] The limiting mechanism includes a limiting cylinder 11, which is installed at the end of the slider 10 away from the arc-shaped locking block 3. A limiting rod 9 is slidably connected to the inner wall of the limiting cylinder 11. Second mounting seats 7 for supporting the limiting rod 9 are installed at both ends of the limiting rod 9. The second mounting seats 7 are installed at the lower end of the mounting housing 1. A buffer pad 13 for buffering the limiting cylinder 11 is installed on the side wall of the limiting rod 9 near the second mounting seat 7. A linear bearing for moving along the side wall of the limiting rod 9 is installed on the inner wall of the limiting cylinder 11.

[0055] The dustproof mechanism includes a dustproof belt 2. Mounting brackets 31 are vertically mounted on the mounting housings 1 at both ends of the slide groove 30. The mounting brackets 31 are located on the side of the mounting housing 1 away from the right push rod housing 21 and the left push rod housing 22. The upper and lower ends of the mounting brackets 31 are rotatably connected to guide rollers 32. The dustproof belt 2 is sleeved on the side wall of the guide rollers 32. The upper end of the dustproof belt 2 is in close contact with the mounting housing 1 at the lower end of the slide groove 30. The slider 10 is mounted on the dustproof belt 2.

[0056] In use, the operator pushes the right push rod housing 21 or the left push rod housing 22, which causes the slider 10 to slide along the inner wall of the slide groove 30. The slider 10 causes the dustproof belt 2 to move, and the dustproof belt 2 causes the guide roller 32 to rotate, and the dustproof belt 2 seals the slide groove 30 to prevent dust.

[0057] The analog measurement mechanism includes a magnetic strip 12, which is obliquely installed at the lower end of the mounting housing 1 between two slide grooves 30. The magnetic strip 12 is not parallel to the slide grooves 30. A Hall PCB 20 that works with the magnetic strip 12 is installed on the side wall of the magnetic strip 12 opposite to the slider 10.

[0058] When in use, the right push rod housing 21 or the left push rod housing 22 moves, which drives the slider 10 to move. The slider 10 drives the Hall PCB 20 to move. Under the action of the Hall effect, the Hall PCB 20 will output an analog signal.

[0059] The push rod opening and closing mechanism includes a mounting plate 28. A pin hole 23 is provided at the lower end of the side wall of the left push rod housing 22 near the right push rod housing 21. A moving rod 26 is slidably connected to the bottom of the right push rod housing 21. The end of the moving rod 26 away from the left push rod housing 22 passes through the side wall of the right push rod housing 21 and is equipped with a handle for easy movement by the user. A pin 29 that cooperates with the pin hole 23 is installed at the end of the moving rod 26 near the left push rod housing 22. The end of the pin 29 away from the moving rod 26 passes through the side wall of the right push rod housing 21 and is inserted into the inside of the pin hole 23. The mounting plate 28 is provided with a detection component for detecting whether the pin 29 is inserted into the pin hole 23.

[0060] The detection component includes a connecting frame 24, which is mounted on the side wall of the moving rod 26 near the mounting plate 28. A baffle 25 is installed at one end of the connecting frame 24 near the mounting plate 28. An infrared pair 27 that works with the baffle 25 is installed on one side of the mounting plate 28 near the connecting frame 24. The baffle 25 is disposed between the infrared pairs 27.

[0061] When separating the right push rod housing 21 and the left push rod housing 22, the user pulls the moving rod 26 to move it away from the left push rod housing 22. The moving rod 26 causes the pin 29 to disengage from the pin hole 23, thus separating the left push rod housing 22 and the right push rod housing 21. At the same time, the moving rod 26 causes the connecting frame 24 to move, and the connecting frame 24 causes the baffle 25 to move. The baffle 25 moves out of the space between the infrared phototransistors 27, thereby enabling the infrared phototransistors 27 to communicate with the signal. This indicates that the right push rod housing 21 and the left push rod housing 22 are separated at this time.

[0062] When the right push rod housing 21 and the left push rod housing 22 are merged, the user pushes the moving rod 26 to move towards the left push rod housing 22. The moving rod 26 drives the pin 29 to insert into the pin hole 23, thereby merging the right push rod housing 21 and the left push rod housing 22. At the same time, the moving rod 26 drives the connecting frame 24 to move, and the connecting frame 24 drives the baffle 25 to move. The baffle 25 moves between the infrared phototransistors 27 and blocks the signal of the infrared phototransistors 27. At this time, the signal of the infrared phototransistors 27 cannot be connected, indicating that the right push rod housing 21 and the left push rod housing 22 are merged together.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
