Description

Technical Field

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

[0002] The HOTAS flight simulator joystick is a concept widely used in modern fighter jets. Translated as "two-hands-on-stick" or "dual-stick control system," it integrates cockpit system operations onto the throttle and joystick buttons, 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 a real fighter jet, meeting the user's needs for flight simulation. The A-axis reset function is a feature typically found on HOTAS joysticks, which usually have an A-axis torsion function. This structure needs to possess technical characteristics such as automatic reset, accurate detection of rotational simulation quantities, lightweight design, and linear feedback force. Common A-axis reset structures are fixed to the base and cannot be detached from the joystick head. Users need to purchase different complete joystick sets to simulate different aircraft types, resulting in poor expandability.

[0003] Based on this, a flight simulator joystick A-axis reset structure is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0004] The purpose of this invention is to provide a reset structure for the A-axis of a flight simulator joystick, in order to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The flight simulator joystick A-axis reset structure includes an A-axis and a housing. A limit seat is sleeved on the upper end of the A-axis, and the housing is fitted on the upper end of the limit seat. The limit seat and the housing are fixedly connected by a connecting assembly. An adjustable torsion spring is fitted inside the housing, with one end of the adjustable torsion spring tightly attached to one side of the limit seat. The housing is fixedly installed inside the joystick assembly. A potentiometer is fitted on the upper end of the housing, and a compression spring is fitted on the upper end of the potentiometer.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4 As shown, the flight simulator joystick A-axis reset structure includes an A-axis 13 and a housing 17. A limiting seat 14 is sleeved on the upper end of the A-axis 13, and the housing 17 is fitted on the upper end of the limiting seat 14. The limiting seat 14 and the housing 17 are fixedly connected by a connecting assembly. An adjustable torsion spring 19 is fitted inside the housing 17, with one end of the adjustable torsion spring 19 tightly attached to one side of the limiting seat 14. The housing 17 is fixedly installed inside the joystick assembly. A potentiometer 20 is fitted on the upper end of the housing 17, and a compression spring 21 is fitted on the upper end of the potentiometer 20. The compression spring 21 is fixedly installed on the limiting slot 18. A base cable guide 23 is fitted on the bottom end of the A-axis 13. The base cable guide 23 is fixedly connected to the external control base by a pin fixing shaft 26. A fixing mechanism is provided at the bottom end of the A-axis 13 to facilitate the fixed connection between the A-axis 13 and the base cable guide 23.

[0024] The connecting assembly includes two symmetrically arranged locking rods 16, which are fixedly mounted on the upper end of the limiting seat 14. The locking rods 16 are L-shaped. The housing 17 has a limiting groove 18 corresponding to the position of the horizontal bar of the locking rod 16. The bottom end of the horizontal bar of the locking rod 16 is in close contact with the bottom end of the limiting groove 18. The upper edge of the horizontal bar of the limiting groove 18 is chamfered. In use, the housing 17 is sleeved on the upper end of the limiting seat 14, so that the bottom end of the housing 17 matches the chamfered edge of the horizontal bar of the locking rod 16, causing the locking rod 16 to deform. When the housing 17 is detached from the locking rod 16, the locking rod 16 returns to its initial state, so that the bottom end of the horizontal bar of the locking rod 16 is in close contact with the bottom end of the limiting groove 18, thereby fixing the housing 17 and the limiting seat 14.

[0025] The handle assembly includes a first handle housing 11 and a second handle housing 12, which are symmetrically arranged. The first handle housing 11 and the second handle housing 12 are fixedly connected by a plurality of first screws. The housing 17 is fixedly connected to the first handle housing 11 and the second handle housing 12 by a plurality of second screws. This facilitates the installation of the first handle housing 11, the second handle housing 12 and the housing 17 during use.

[0026] The A-axis 13 is provided with an arc-shaped limiting groove, and a limiting shaft 15 is slidably provided in the arc-shaped limiting groove. The limiting shaft 15 is fixedly provided inside the handle assembly, which facilitates the installation and fixation of the A-axis 13 during use.

[0027] The limiting slot 18 and the arc-shaped limiting slot have equal limiting angles for the limiting shaft 15 and the locking rod 16. In use, this facilitates limiting the adjustable torsion spring 19 to rotate within the 15-degree range of the limiting shaft.

[0028] A bearing 22 is sleeved on the A-axis 13. The inner ring of the bearing 22 is tightly fitted to the A-axis 13, and the outer ring of the bearing 22 is tightly fitted to the first handle housing 11 and the second handle housing 12. In use, the bearing 22 rotates synchronously with the housing 17, which plays a role in balancing the force and adjusting the rotation of the central axis, and preventing rotational deviation.

[0029] The fixing mechanism includes a knob base 25, which is fixedly connected to the base guide shaft 23 by several third screws. A connecting knob 24 is fitted on the upper end of the knob base 25. The inner side of the connecting knob 24 is in close contact with the upper fixing tube of the base guide shaft 23. The connection between the connecting knob 24 and the fixing tube is threaded. The upper end of the connecting knob 24 has a circular through hole. In use, when it is necessary to fix the A-axis 13 and the base guide shaft 23, the knob base 25 is installed on the upper end of the base guide shaft 23 and fixed by several third screws. Then the connecting knob 24 is installed and fixed by the thread. The upper inner side of the connecting knob 24 is then in close contact with the A-axis 13, thereby fixing the A-axis 13 and the base guide shaft 23.

[0030] A sliding rod 27 is slidably installed in the mounting hole at the bottom of the A-axis 13. A spring 28 is fixed between the bottom end of the sliding rod 27 and the bottom end of the mounting hole. A ball bearing is fitted at one end of the sliding rod 27. Several arc-shaped grooves are provided on the upper inner side of the connecting knob 24 at the position corresponding to the ball bearing. In use, these grooves help to limit the rotation of the connecting knob 24, thereby increasing the stability of the connecting knob 24 during use.

[0031] The above embodiment discloses a flight simulator joystick A-axis reset structure. When installation is required, the base guide shaft 23 is sleeved onto the external control base, and the base guide shaft 23 is fixed by the pin fixing shaft 26. The knob base 25 is installed onto the upper end of the base guide shaft 23 and fixed by several third screws. Then, the connecting knob 24 is installed and fixed by the thread. The upper inner side of the connecting knob 24 then fits tightly against the A-axis 13, thereby fixing the A-axis 13 to the base guide shaft 23. Simultaneously, a ball bearing at one end of the sliding rod 27 engages with the arc-shaped groove at the upper inner end of the connecting knob 24, facilitating the restriction of the connecting knob 24's rotation during use, thus increasing the ease of use of the connecting knob 24. To ensure stability, the bearing 22 is installed on the A-axis 13, and then the limiting seat 14 is sleeved on one end of the A-axis 13. The housing 17 is sleeved on the upper end of the limiting seat 14, so that the bottom end of the housing 17 fits with the chamfer on one side of the crossbar of the locking rod 16, causing the locking rod 16 to deform. When the housing 17 is disengaged from the locking rod 16, the locking rod 16 returns to its initial state, so that the bottom end of the crossbar of the locking rod 16 is in close contact with the bottom end of the limiting groove 18, thereby fixing the housing 17 and the limiting seat 14. The potentiometer 20 is installed on the upper end of the housing 17 and fixed by the compression spring 21. Then, the first handle housing 11 and the second handle housing 12 are installed in the working position and fixed to the A-axis 13 by the first screw and the second screw.
