Description

Technical Field

[0001] This utility model relates to the field of flight simulator technology, and in particular to a shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator. Background Technology

[0002] A simulator used to simulate aircraft flight is called an aircraft flight simulator. It typically consists of five main parts: a simulated cockpit, a motion system, a visual system, a computer system, and an instructor's control console. Due to its outstanding advantages such as safety, reliability, convenience, economy, high efficiency, and independence from weather conditions, flight simulators have developed rapidly. With advancements in science and technology, flight simulators have become increasingly sophisticated. Modern flight simulators integrate computer, mechanical, electrical, electronic, automatic control, hydraulic, and optical technologies, making them highly complex and precise high-tech devices.

[0003] The six-axis platform (six-degree-of-freedom motion platform) used in flight simulators is a high-precision device that achieves six degrees of freedom (X / Y / Z translation and pitch / yaw / roll) motion in space through six electric or hydraulic actuators. Its core function is to reproduce the dynamic attitude of an aircraft, providing the pilot with realistic tactile feedback. The six-axis platform generates high-frequency vibrations and impact loads when simulating flight attitudes. If these are directly transmitted to the cockpit, they may affect the pilot's operating experience and the stability of the equipment. The shock absorption mechanism absorbs mechanical vibration energy, reducing the rigid impact of platform movement on the cockpit and improving the comfort and safety of the simulator. However, the following drawbacks still need to be addressed: uneven shock absorption distribution can lead to a strong sense of vibration felt by the pilot. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator.

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

[0006] A shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator includes a base. The top of the base is fixedly installed to the bottom of the cockpit. A six-axis motion platform is provided at the bottom of the base. Telescopic components are rotatably installed at the four corners of the bottom of the base. A pressure-distributing shock-absorbing component is rotatably installed at the upper end of the fixed section of the telescopic component and the bottom of the cockpit. A connecting rod is rotatably installed at the upper end of the movable section of the telescopic component. A first pressure member is fixedly installed in the middle of the bottom of the base. A second pressure member is fixedly installed in the middle of the top of the six-axis motion platform. Both the first and second pressure members include pressure seats. Elastic columns and return springs are fixedly installed on the outer walls of opposite ends of the two pressure seats. Multiple first and second notches are provided around the circumference of the two pressure seats. A first strut and a second strut are rotatably installed inside the two second notches in the same row, respectively. A transfer block is rotatably installed between the ends of the first and second struts. Magnetic plates are embedded in the outer walls of opposite ends of the first and second struts. Two magnetic plates on the same side repel each other. The opposite ends of the two pressure seats also repel each other.

[0007] Preferably, the inclined end of the pressure-shaping damping component is located in the middle of the tops of two adjacent telescopic members, and the pressure-shaping damping component includes a bidirectional sleeve.

[0008] Preferably, each of the two outlet ends of the bidirectional sleeve is slidably sleeved with a movable rod, and each of the two movable rods is sleeved with a first support spring at its opposite circumference. Each of the two movable rods is fixedly connected with a sleeve at its opposite circumference. Each of the two sleeves is slidably sleeved with a T-shaped rod, and each of the T-shaped rods is sleeved with a second support spring at its circumference. Each of the two T-shaped rods is fixedly installed with a mating magnetic block at its opposite circumference.

[0009] Preferably, the first support spring is located inside the bidirectional sleeve, the second support spring is located inside the sleeve, and the opposite ends of the two mating magnetic blocks repel each other.

[0010] Preferably, the end of each link is rotatably connected to the first notch of the first pressure member on the same side.

[0011] Preferably, the reset spring is sleeved with the elastic post.

[0012] Preferably, the first and second notches of the two pressure seats are arranged alternately.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model proposes a shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator. A telescopic component is located between the six-axis motion platform and the cockpit, providing both support and shock absorption. A pressure-distributing shock-absorbing assembly is rotatably mounted on the upper end of the fixed section of the telescopic component and the bottom end of the cockpit. A connecting rod is rotatably provided between the upper end of the movable section of the telescopic component and a first notch. This not only distributes the pressure on the telescopic component, reducing vibration, but also allows the telescopic component to quickly return to its original position after compression. A first pressure member is located at the bottom of the cockpit, and a second pressure member is located at the top of the six-axis motion platform. Multiple sets of first and second struts between the first and second pressure members form a rhomboid buffer cover. The buffer cover resists shock absorption by having two magnetic plates repel each other at opposite ends of the two pressure seats, further reducing the pilot's turbulence and vibration sensation. Furthermore, the alternating arrangement of the first and second notches of the two pressure seats allows for the alternating arrangement of multiple telescopic components and multiple sets of first and second struts, further strengthening the pressure-distributing buffering effect of the six-axis motion platform on the bottom of the cockpit.

[0015] 2. The present invention proposes a shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator. By positioning the inclined end of the pressure-distributing shock-absorbing component at the middle of the tops of two adjacent telescopic components, the buffer cover composed of the pressure-distributing shock-absorbing component, telescopic components, and multiple sets of first and second support rods can provide multi-directional and multi-dimensional shock absorption for the cockpit. The pressure-distributing shock-absorbing component includes a bidirectional sleeve, a movable rod, a first support spring, a sleeve, a T-shaped rod, a second support spring, and a docking magnetic block. This allows the pressure-distributing shock-absorbing component to not only support the cockpit and the six-axis motion platform but also provide multi-level buffering and shock absorption, thereby achieving a better shock absorption effect and optimizing the vibration experience for the pilot.

[0021] Reference Figure 1-4 A shock-absorbing connection structure between a six-axis platform and a cockpit for a flight simulator includes a base 1, with the top of the base 1 fixedly installed to the bottom of the cockpit. A six-axis motion platform is provided at the bottom of the base 1. Telescopic components 2 are rotatably installed at the four corners of the bottom of the base 1. A pressure-distributing shock-absorbing assembly is rotatably installed at the upper end of the fixed section of the telescopic component 2 and the bottom of the cockpit. A connecting rod 4 is rotatably installed at the upper end of the movable section of the telescopic component 2. A first pressure component 5 is fixedly installed in the middle of the bottom of the base 1, and a second pressure component 6 is fixedly installed in the middle of the top of the six-axis motion platform. Both the first pressure component 5 and the second pressure component 6 include a pressure seat 9. Both pressure seats 9 have elastic columns 7 and return springs 8 fixedly installed on the outer walls of opposite ends. Both pressure seats 9 have multiple first notches 10 and second notches 11 around their circumferences. The first support rod 12 and the second support rod 13 are rotatably installed inside the two second notches 11 in the same column, and a transfer block 15 is rotatably installed between the ends of the first support rod 12 and the second support rod 13. Magnetic plates 14 are embedded in the outer walls of opposite ends of the first support rod 12 and the second support rod 13. The two magnetic plates 14 on the same side repel each other, and the opposite ends of the two pressure seats 9 repel each other.

[0022] In this utility model, the inclined end of the pressure-shaping damping component is located in the middle of the tops of two adjacent telescopic members 2, and the pressure-shaping damping component includes a bidirectional sleeve 3.

[0023] Both outlet ends of the bidirectional sleeve 3 are slidably fitted with movable rods 16, and the opposite ends of the two movable rods 16 are fitted with first support springs 17. The opposite ends of the two movable rods 16 are fixedly connected with sleeves 18. T-shaped rods 19 are slidably fitted inside the two sleeves 18, and second support springs 20 are fitted around the circumference of the T-shaped rods 19. The opposite ends of the two T-shaped rods 19 are fixedly installed with mating magnetic blocks 21.

[0024] The first support spring 17 is located inside the bidirectional sleeve 3, the second support spring 20 is located inside the sleeve 18, and the two mating magnetic blocks 21 repel each other at their opposite ends.

[0025] The end of each link 4 is rotatably connected to the first notch 10 of the first pressure member 5 on the same side;

[0026] The return spring 8 is sleeved with the elastic post 7;

[0027] The first notch 10 and the second notch 11 of the two pressure seats 9 are arranged alternately.

[0028] Working principle: The telescopic component 2 is located between the six-axis motion platform and the cockpit, which can both support and extend to reduce shock. The upper end of the fixed section of the telescopic component 2 is rotatably installed with a pressure-distributing shock-absorbing component at the bottom of the cockpit. The upper end of the movable section of the telescopic component 2 is rotatably connected to the first notch 5. This not only disperses the pressure on the telescopic component 2 to reduce vibration, but also allows the telescopic component 2 to quickly return to its original position after compression. The bottom of the cockpit is provided with a first pressure component 5, and the top of the six-axis motion platform is provided with a second pressure component 6. Multiple sets of first support rods 12 and second support rods 13 between the first pressure component 5 and the second pressure component 6 form a diamond-shaped buffer cover. The buffer cover resists shock by mutual repulsion between the two pressure seats 9 and the two magnetic plates 14 at their opposite ends, further reducing the pilot's turbulence and vibration. The first notch 10 and the second notch 11 of the two pressure seats 9 are arranged alternately, so that multiple telescopic components 2 and multiple sets of first support rods 12 and second support rods 13 are arranged alternately, which further strengthens the pressure-distributing buffer of the six-axis motion platform on the bottom of the cockpit.

[0029] By positioning the inclined end of the pressure-distributing shock absorber at the midpoint between the tops of two adjacent telescopic components 2, the buffer cover composed of the pressure-distributing shock absorber, telescopic components 2, and multiple sets of first support rods 12 and second support rods 13 can provide multi-directional and multi-dimensional shock absorption for the cockpit. The pressure-distributing shock absorber includes a bidirectional sleeve 3, a movable rod 16, a first support spring 17, a sleeve 18, a T-shaped rod 19, a second support spring 20, and a docking magnet 21. This allows the pressure-distributing shock absorber to not only support the cockpit and the six-axis motion platform but also provide multi-level shock absorption, thereby achieving better shock absorption and optimizing the pilot's vibration experience during flight.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
