Description

Technical Field

[0001] The present invention relates to the technical field of shock absorbing devices, and in particular to a shock absorbing mechanism suitable for an electrical module of a flight simulator. Background Art

[0002] With the rapid development of aerospace technology, flight simulators, as key equipment for pilot training and aircraft performance testing, are becoming increasingly important in terms of operational stability and reliability. During simulated flight, the six-degree-of-freedom motion of the motion platform, the high-frequency operation of the motor drive system, and external environmental vibrations create continuous impact and vibration interference on the internal electrical modules. Precision electronic components in these modules (such as GPUs, CPUs, and sensor circuit boards) are extremely sensitive to vibration. Prolonged exposure to vibration can lead to solder joint fatigue and poor contact, as well as signal transmission deviations and data acquisition inaccuracies, severely impacting the simulator's simulation accuracy and service life.

[0003] Traditional flight simulator shock absorption mechanisms often utilize fixed-parameter damping components, such as springs with a single stiffness and rubber pads. While this type of damping can mitigate vibration to a certain extent, it has significant limitations. When faced with low-frequency vibrations, fixed-stiffness springs can cause resonance due to the proximity of their natural frequency to the vibration frequency, exacerbating the vibration damage. Under high-frequency vibration conditions, they struggle to provide sufficient damping and elastic support, significantly reducing the damping effect. Furthermore, existing damping technologies struggle to adapt their damping performance in real time to dynamic changes in vibration frequency, making them inadequate for the complex and changing vibration environments of flight simulators. Summary of the Invention

[0004] The present invention provides a shock absorbing mechanism for an electrical module of a flight simulator, so as to solve the problem that the existing shock absorbing device is difficult to adjust the shock absorbing performance in real time according to the dynamic change of the vibration frequency.

[0005] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0006] A shock absorbing mechanism for an electrical module of a flight simulator, comprising a protective assembly for mounting the electrical module, a first shock absorbing assembly connected to the upper portion of the protective assembly, the first shock absorbing assembly comprising a mounting frame, a slide rod slidably connected within the mounting frame, a hinge seat fixedly connected to the bottom of the slide rod, the hinge seat connected to the protective assembly via a second shock absorbing assembly, a circular plate fixedly connected to the top end of the slide rod, and a first spring connected between the circular plate and the mounting frame;

[0007] An adjustment assembly is provided between the articulated seat and the mounting bracket, and the adjustment assembly includes a first connecting rod and a second connecting rod hinged to each other, and the first connecting rod and the second connecting rod are hinged to the mounting bracket and the articulated seat respectively. When the sliding frequency of the sliding rod in the mounting bracket increases, the angle between the first connecting rod and the second connecting rod toward the sliding rod increases, thereby increasing the preload force of the first spring.

[0008] Furthermore, the adjustment assembly also includes a storage roller rotatably connected to the hinged seat, a pull rope is fixedly connected to the storage roller, and the end of the pull rope away from the storage roller is fixedly connected to the first connecting rod or the second connecting rod. When the storage roller stores the pull rope, it can drive the first connecting rod and the second connecting rod to increase the angle between them toward the sliding rod.

[0009] Furthermore, the hinge seat is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a rack, and the storage roller is fixedly connected to a gear meshing with the rack.

[0012] Furthermore, the number of the first connecting rods and the number of the second connecting rods are both two, and the two first connecting rods and the two second connecting rods are symmetrically arranged on both sides of the sliding rod.

[0013] Furthermore, the second shock absorbing assembly includes two first swing arms symmetrically hinged to the protection assembly, the ends of the two first swing arms are hinged to the second swing arms, and the ends of the two second swing arms are hinged to the hinge seat;

[0014] A mounting seat is hingedly connected to the middle portion of each of the two first swing arms, and a second spring is fixedly connected between the two mounting seats.

[0015] Furthermore, the middle parts of the two first rocker arms are fixedly connected to electric push rods, which can abut against the mounting seat when extended, so that the mounting seat is locked to the first rocker arm. When the sliding frequency of the sliding rod in the mounting frame increases, the electric push rod extends.

[0016] Furthermore, the protection assembly includes an installation box, a box door is connected to the installation box, the electrical module is installed in the installation box, and the bottoms of the two first rocker arms are symmetrically hinged to the top wall of the installation box.

[0017] Furthermore, a first limit frame and a second limit frame are placed on the upper and lower sides of the electrical module in the installation box respectively, and two mounting plates are symmetrically and slidingly connected on both sides of the installation box. A first wedge block and a second wedge block are fixedly connected to the two mounting plates, and the first limit frame and the second limit frame are both provided with inclined surfaces that cooperate with the first wedge block and the second wedge block. When the two mounting plates are close to each other, they can drive the first limit frame and the second limit frame to clamp the electrical module.

[0018] Furthermore, a guide rod is fixedly connected to the mounting plate, and a through hole is opened on the side wall of the mounting box to cooperate with the guide rod;

[0019] An electric rotating rod is rotatably connected to the side wall of the mounting box, and a cam is fixedly connected to the electric rotating rod. The side wall of the cam is in contact with the mounting plate. When the sliding frequency of the sliding rod in the mounting frame increases, the electric rotating rod rotates to cause the cam to push the mounting plate to slide.

[0020] The beneficial effects of the present invention are analyzed as follows:

[0021] A shock absorbing mechanism suitable for an electrical module of a flight simulator comprises a protective assembly for installing the electrical module, wherein the upper portion of the protective assembly is connected to a first shock absorbing assembly, the first shock absorbing assembly comprises a mounting frame, a sliding rod is slidably connected within the mounting frame, the bottom of the sliding rod is fixedly connected to a hinge seat, the hinge seat is connected to the protective assembly via a second shock absorbing assembly, the top end of the sliding rod is fixedly connected to a circular plate, a first spring is connected between the circular plate and the mounting frame; an adjustment assembly is provided between the hinge seat and the mounting frame, the adjustment assembly comprises a first connecting rod and a second connecting rod hinged to each other, the first connecting rod and the second connecting rod are hinged to the mounting frame and the hinge seat respectively, when the sliding frequency of the sliding rod in the mounting frame increases, the angle between the first connecting rod and the second connecting rod toward the sliding rod increases, thereby increasing the preload force of the first spring.

[0022] When the protective component is subjected to vibration, the sliding rod slides relative to the mounting frame to cushion the vibration. At this time, the first spring is compressed and released to cushion the vibration. When the control system obtains the increase in the reciprocating sliding frequency of the circular plate, it means that the current vibration frequency has increased. At this time, the control system controls the first connecting rod and the second connecting rod to swing, and the angle between the two toward the sliding rod increases, so that the distance between the mounting frame and the hinge seat increases. At this time, the circular plate moves downward relative to the mounting frame, so that the initial length of the first spring becomes shorter, providing preload force for the first spring, and increasing the elastic spring coefficient of the first spring in disguise, so that the first spring can withstand high-frequency vibrations.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] like Figure 1-Figure 7 As shown, a shock absorbing mechanism for an electrical module of a flight simulator includes a protective assembly 400 for installing the electrical module. The upper portion of the protective assembly 400 is connected to a first shock absorbing assembly 100. The first shock absorbing assembly 100 includes a mounting frame 110. A slide rod 130 is slidably connected to the mounting frame 110. The bottom of the slide rod 130 is fixedly connected to an articulated seat 160. The articulated seat 160 is connected to the protective assembly 400 through a second shock absorbing assembly 200. The top of the slide rod 130 is fixedly connected to a circular plate 140. The circular plate 140 is fixedly connected to the mounting frame 110. A first spring 150 is connected between the mounting frame 110; an adjustment assembly 300 is arranged between the hinge seat 160 and the mounting frame 110, and the adjustment assembly 300 includes a first link 310 and a second link 320 hinged to each other. The first link 310 and the second link 320 are hinged to the mounting frame 110 and the hinge seat 160 respectively. When the sliding frequency of the slide bar 130 in the mounting frame 110 increases, the angle between the first link 310 and the second link 320 toward the slide bar 130 increases, thereby increasing the preload force of the first spring 150.

[0037] The working mechanism of the shock absorbing mechanism of the electrical module for a flight simulator provided in this embodiment is as follows:

[0038] The electrical module is installed in the protective assembly 400, and the mounting bracket 110 of the first shock absorbing assembly 100 is installed in the flight simulator. A push switch or a displacement sensor is provided in the mounting bracket 110 to detect the sliding of the circular plate 140. The push switch receives the number of presses per unit time of the circular plate 140 to determine the current vibration frequency, and the displacement sensor detects the displacement distance and speed of the displacement direction of the circular plate 140 to determine the current vibration frequency.

[0039] When the protective component 400 is vibrated, the slide bar 130 slides relative to the mounting bracket 110 to cushion the vibration. At this time, the first spring 150 is compressed and released to cushion the vibration. When the control system obtains the increase in the reciprocating sliding frequency of the circular plate 140, it means that the current vibration frequency has increased. At this time, the control system controls the first connecting rod 310 and the second connecting rod 320 to swing, and the angle between the two toward the slide bar 130 increases, so that the distance between the mounting bracket 110 and the hinge seat 160 increases. At this time, the circular plate 140 moves downward relative to the mounting bracket 110, so that the initial length of the first spring 150 becomes shorter, providing a preload force for the first spring 150, thereby increasing the elastic spring coefficient of the first spring 150 in disguise, thereby enabling the first spring 150 to withstand high-frequency vibrations.

[0040] Among the optional methods of this embodiment, the more preferred ones are:

[0041] The adjustment assembly 300 also includes a storage roller 360 rotatably connected to the hinged seat 160, and a pull rope 370 is fixedly connected to the storage roller 360. The end of the pull rope 370 away from the storage roller 360 is fixedly connected to the first link 310 or the second link 320. When the storage roller 360 stores the pull rope 370, it can drive the first link 310 and the second link 320 toward the sliding rod 130 to increase the included angle.

[0042] The hinged seat 160 is fixedly connected to a swivel seat 161, and the storage roller 360 is rotatably connected to the swivel seat 161. The end of the pull rope 370 is fixedly connected to the storage roller 360. When the storage roller 360 rotates, the pull rope 370 can be reeled in. At this time, the pull rope 370 can pull the first connecting rod 310 or the second connecting rod 320 connected thereto, so that the angle between the first connecting rod 310 and the second connecting rod 320 toward the sliding rod 130 becomes larger, thereby driving the first spring 150 to be subjected to pre-tightening force.

[0043] Among the optional methods of this embodiment, the more preferred ones are:

[0044] The articulated seat 160 is fixedly connected to an electric telescopic rod 330 , an output end of the electric telescopic rod 330 is fixedly connected to a rack 340 , and the storage roller 360 is fixedly connected to a gear 350 meshing with the rack 340 .

[0045] The control system derives the vibration frequency currently experienced by the protective assembly 400 from the frequency of the reciprocating motion of the circular plate 140. The electric telescopic rod 330 has multiple extension gears, and the range of the vibration frequency corresponds one-to-one to the multiple extension gears of the electric telescopic rod 330. The control system uses an interpolation function method to control the extension of the electric telescopic rod 330 to the corresponding gear length based on the current vibration frequency. When the electric telescopic rod 330 is extended, it drives the rack 340 at its output end to slide. The rack 340 drives the gear 350 to rotate, thereby rotating the storage roller 360. Different extension lengths of the electric telescopic rod 330 result in different rotation angles of the storage roller 360, which in turn results in different storage lengths of the pull rope 370. This, in turn, causes different changes in the angle between the first connecting rod 310 and the second connecting rod 320, thereby imparting different preload forces to the first spring 150.

[0046] Among the optional methods of this embodiment, the more preferred ones are:

[0047] The top of the mounting frame 110 is fixedly connected to a hinge ball 120, which is hinged in the flight simulator; the top of the mounting frame 110 is fixedly connected to a plurality of elastic ropes 170 in a circular array, and the ends of the plurality of elastic ropes 170 are fixedly connected to the flight simulator.

[0048] The hinge ball 120 allows the mounting frame 110 to swing relative to the flight simulator. The weight of the protective assembly 400 attached to the bottom of the mounting frame 110 applies force to the mounting frame 110, keeping it in an upright position. This ensures that the electrical components within the protective assembly 400 are subjected to consistent vibration regardless of the movement of the flight simulator.

[0049] The provision of the elastic rope 170 can prevent the mounting bracket 110 from rotating, thereby ensuring that the wiring harness of the electrical module will not be pulled and fall off.

[0050] Among the optional methods of this embodiment, the more preferred ones are:

[0051] There are two first connecting rods 310 and two second connecting rods 320 , and the two first connecting rods 310 and the two second connecting rods 320 are symmetrically arranged on both sides of the sliding rod 130 .

[0052] The bronze drum is provided with two first connecting rods 310 and a second connecting rod 320 so that the mounting frame 110 can be subjected to a uniform lifting force.

[0053] Regarding the structure of the second shock absorbing assembly 200, specifically:

[0054] The second shock-absorbing assembly 200 includes two first rocker arms 210 symmetrically hinged to the protective assembly 400, the ends of the two first rocker arms 210 are hinged to the second rocker arms 250, and the ends of the two second rocker arms 250 are hinged to the hinge seat 160; the middle parts of the two first rocker arms 210 are hinged to the mounting seat 220, and a second spring 230 is fixedly connected between the two mounting seats 220.

[0055] When the protective assembly 400 is subjected to vertical vibration, the slide bar 130 slides relative to the mounting frame 110, causing the first spring 150 to be compressed and to perform shock absorption. The downward movement of the protective assembly 400 also drives the two first swing rods 210 to move downward. At this time, the compression resistance of the first spring 150 causes the second swing rod 250 to move downward. Figure 2 In this state, the two second swing rods 250 swing upward relative to the first swing rod 210, and the ends of the two second swing rods 250 are hinged to the ends of the hinge seat 160, so that the ends of the two first swing rods 210 close to the second swing rod 250 can approach each other. At this time, the distance between the middle parts of the two first swing rods 210 becomes shorter, which makes the second spring 230 compressed, and the second spring 230 plays a further shock-absorbing effect here.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] The middle parts of the two first rocker arms 210 are fixedly connected to electric push rods 240. When the electric push rods 240 are extended, they can abut against the mounting base 220, so that the mounting base 220 is locked to the first rocker arms 210. When the sliding frequency of the slide rod 130 in the mounting frame 110 increases, the electric push rods 240 extend.

[0058] When the vibration frequency increases, in order to prevent the mounting base 220 from swinging relative to the first swing rod 210 due to vibration and generating resonance, the control system controls the electric push rod 240 to extend, so that the electric push rod 240 applies a thrust to the mounting base 220, so that the mounting base 220 no longer swings relative to the first swing rod 210, thereby preventing the mounting base 220 from generating resonance;

[0059] The timing of the extension of the electric push rod 240 coincides with the initial extension of the electric telescopic rod 330, and if the electric telescopic rod 330 continues to extend or the electric telescopic rod 330 is not shortened back to the shortest state, the electric push rod 240 is always in the extended state;

[0060] In addition, an electric clamp can be optionally installed on the mounting box 410 according to the k value of the second spring 230. When the electric push rod 240 extends, the electric clamp firmly clamps the second spring 230, thereby preventing the second spring 230 from resonating.

[0061] Regarding the structure of the protection component 400, specifically:

[0062] The protection assembly 400 includes an installation box 410 , to which a door 420 is connected. The electrical module is installed in the installation box 410 , and the bottoms of the two first swing arms 210 are symmetrically hinged to the top wall of the installation box 410 .

[0063] By opening the box door 420 , it is convenient to install or repair the electrical modules in the installation box 410 . The arrangement of the installation box 410 prevents the internal electrical modules from being damaged by external impact.

[0064] Among the optional methods of this embodiment, the more preferred ones are:

[0065] A first limit frame 461 and a second limit frame 471 are placed on the upper and lower sides of the electrical module in the installation box 410 respectively. Two mounting plates 430 are symmetrically and slidingly connected on both sides of the installation box 410. A first wedge block 460 and a second wedge block 470 are fixedly connected to the two mounting plates 430. The first limit frame 461 and the second limit frame 471 are both provided with inclined surfaces that cooperate with the first wedge block 460 and the second wedge block 470. When the two mounting plates 430 approach each other, they can drive the first limit frame 461 and the second limit frame 471 to clamp the electrical module.

[0066] In the initial state, the first limit frame 461 and the second limit frame 471 are in contact with the upper surface and the lower surface of the electrical module, but the contact parts do not have a large pressure and only play a supporting role for the electrical module. When the vibration frequency of the installation box 410 increases, the two mounting plates 430 both move toward the installation box 410. At this time, the first wedge block 460 on the mounting plate 430 slides on the end inclined surface of the first limit frame 461 to apply a thrust to it, so that the first limit frame 461 can move downward, and the second wedge block 470 on the mounting plate 430 can slide on the end inclined surface of the second limit frame 471 to apply a thrust to it, so that the second limit frame 471 can move upward, so that the clamping force of the first limit frame 461 and the second limit frame 471 on the electrical module is increased, thereby improving the stability of the electrical module in a high-frequency vibration environment.

[0067] Among the optional methods of this embodiment, the more preferred ones are:

[0068] A guide rod 431 is fixedly connected to the mounting plate 430, and a through hole that cooperates with the guide rod 431 is opened on the side wall of the mounting box 410; an electric rotating rod 440 is rotatably connected to the side wall of the mounting box 410, and a cam 450 is fixedly connected to the electric rotating rod 440. The side wall of the cam 450 is in contact with the mounting plate 430. When the sliding frequency of the sliding rod 130 in the mounting frame 110 increases, the electric rotating rod 440 rotates to cause the cam 450 to push the mounting plate 430 to slide.

[0069] The guide rod 431 is set to provide guidance for the sliding direction of the mounting plate 430, ensuring that the two mounting plates 430 can slide stably toward the mounting box 410, and setting a vibration frequency threshold. The control system obtains the vibration frequency by detecting the reciprocating sliding frequency of the circular plate 140, and compares this vibration frequency with the set vibration frequency threshold. When the set vibration frequency threshold is exceeded, the control system controls the electric rotating rod 440 to rotate. At this time, the cam 450 pushes the mounting plate 430 to slide, thereby enhancing the clamping force of the first limit frame 461 and the second limit frame 471 on the electrical module, and improving the seismic resistance of the electrical module. When the vibration frequency does not exceed the set vibration frequency threshold, the first limit frame 461 and the second limit frame 471 do not apply a large clamping force to the electrical module, thereby preventing the electrical module from being deformed or damaged due to a large clamping force for a long time.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
