Description

Technical Field

[0001] This application belongs to the field of flight simulation equipment technology, and particularly relates to a throttle device and a flight simulator. Background Technology

[0002] In an era of rapid development of simulators, more and more flight simulators are gradually coming into view, and the functions integrated into various electronic products are becoming more comprehensive and fancy.

[0003] A flight simulator is a machine used to simulate the flight of an aircraft. Devices that simulate the flight of airplanes, missiles, satellites, spacecraft, etc., can all be called flight simulators. They are simulation devices that can reproduce the aircraft and the aerial environment and allow for operation.

[0004] Flight simulators typically include various control sticks, throttles, and switches, allowing users to control the aircraft's attitude and direction. However, existing flight simulators have very long push-pull and pull-back travel on their control sticks. Since different types of aircraft and / or various flight modes require different control travel distances, these simulators cannot meet the varying control travel needs of different aircraft types and flight modes. Utility Model Content

[0005] This application provides a throttle device designed to address the problem that existing flight simulators cannot meet the different control travel requirements of different aircraft types and driving modes.

[0006] This application provides a throttle device for use in a flight simulator, the throttle device comprising:

[0007] A throttle base, comprising a housing, an inwardly accommodating cavity, a rotating shaft disposed within the accommodating cavity, and a through groove connecting the accommodating cavity to the outside of the housing;

[0008] A throttle control lever, comprising a rotating part and a control lever body, wherein one end of the rotating part is rotatably connected to the rotating shaft, and the other end extends out of the through groove and is connected to the control lever body;

[0009] A travel limiter is detachably connected to the throttle base, and the travel limiter includes a first end and a second end disposed opposite to each other along the extending direction of the through groove;

[0010] The travel limiting component has a limiting groove, which is located at the first end or the second end and is recessed towards the second end or the first end.

[0011] The throttle control lever also includes a limiting part, which is connected to the control lever body;

[0012] When the main body of the control lever is rotated to a preset angle, the limiting part is located in the limiting groove and contacts the groove wall.

[0013] The travel limit component is detachably connected to the throttle base. The corresponding travel limit component can be selected and installed on the throttle base according to the aircraft type and flight mode. The travel limit component has a limit groove. When the main body of the throttle control stick is rotated to a preset angle, the limit part on the throttle control stick will contact the groove wall of the limit groove, so that the throttle control stick cannot be pushed or pulled further, thus meeting the control travel requirements of different aircraft types and flight modes.

[0014] Furthermore, the travel limiter has its side surface near the throttle base recessed towards the throttle base.

[0015] By designing the bottom surface of the travel limiter to be concave towards the throttle base, the bottom surface of the travel limiter can fit snugly against the arc-shaped housing of the throttle base, resulting in a more reliable connection.

[0016] Furthermore, the central axis of the travel limiter on the side surface near the throttle base coincides with the rotation axis of the rotating part.

[0017] With the above settings, the side surface of the travel limit component near the throttle base coincides with the arc-shaped trajectory of the limit part, which enables the limit part and the travel limit component to cooperate better.

[0018] Furthermore, the limiting groove is an arc-shaped groove, and the radius of the limiting groove is less than or equal to the arc radius of the side surface of the travel limiting member near the throttle base.

[0019] The above settings enable the limiting part to better engage with the arc-shaped groove, preventing the limiting part from sliding out of the arc-shaped groove and improving the limiting reliability of the stroke limiting component.

[0020] Furthermore, the travel limiting member has a locking portion at one end away from the limiting groove along the extension direction of the through groove, and the thickness of the locking portion is greater than the thickness of the adjacent position of the locking portion on the side close to the limiting groove.

[0021] The above settings provide users with tactile feedback, enhancing the user experience.

[0022] Furthermore, the locking part has a point of maximum thickness, and the absolute value of the thickness change rate of the point of maximum thickness towards the side closer to the limiting groove is greater than the absolute value of the thickness change rate of the side farther away from the limiting groove.

[0023] With the above settings, a smooth transition through the locking mechanism can produce a mechanical feel, resulting in a good user experience.

[0024] Furthermore, the distance from the end of the limiting groove away from the throttle base to the end near the throttle base is greater than the thickness of the locking part.

[0025] With the above settings, when the main body of the control lever rotates to the preset angle, the limiting groove can better restrict the limiting part.

[0026] Furthermore, the throttle base is provided with a positioning groove, and the width of the travel limiter on the side closer to the throttle base is greater than the width of the travel limiter on the side farther away from the throttle base; the width of the positioning groove gradually increases in the direction away from the throttle base.

[0027] With the above settings, the longitudinal section of the travel limit component along the extension direction of the through groove is designed to be larger at the top and smaller at the bottom. At the same time, the positioning groove is designed to have a structure in which the groove width gradually increases from the groove opening to the groove bottom. This makes it less likely for the travel limit component to fall off after it is installed in the positioning groove, thus improving the installation stability and reliability.

[0028] Furthermore, the throttle base is provided with a first magnetic attractor, and the travel limiting member is provided with a second magnetic attractor that magnetically engages with the first magnetic attractor; and / or

[0029] The throttle base is provided with a snap-fit ​​assembly, which is used to fix the travel limiter on the throttle base.

[0030] The travel limit component is locked to the throttle base using a magnetic method or a snap-fit ​​assembly, making the installation simple and reliable.

[0031] Secondly, this application also provides a flight simulator, including the throttle device as described above. Attached Figure Description

Examples of embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application. Furthermore, it should be understood that the specific embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0040] The throttle device provided in this application includes a throttle base 100, which includes a housing with an inwardly arranged cavity. A rotating shaft is disposed within the cavity. The housing has a through groove 110 connecting the cavity to the outside of the housing. A throttle lever 200 includes a rotating part 210 and a lever body 220. One end of the rotating part 210 is rotatably connected to the rotating shaft, and the other end extends from the through groove 110 and is connected to the lever body 220. A travel limiter 300 is detachably connected to the throttle base 100. The stroke limiting member 300 includes a first end 310 and a second end 320 disposed opposite to each other along the extending direction of the through groove 110; the stroke limiting member 300 has a limiting groove 330, the limiting groove 330 is disposed at the first end 310 or the second end 320, and is recessed towards the second end 320 or the first end 310; the throttle control lever 200 also includes a limiting part 230, the limiting part 230 is connected to the control lever body 220; when the control lever body 220 rotates to a preset angle, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330. With the above settings, the travel limiter 300 is detachably connected to the throttle base 100. The corresponding travel limiter 300 can be selected and installed on the throttle base 100 according to the aircraft type and flight mode. The travel limiter 300 has a limit groove 330. When the control stick body 220 of the throttle control stick 200 is rotated to a preset angle, the limit part 230 on the throttle control stick 200 will contact the groove wall of the limit groove 330, so that the throttle control stick 200 cannot be pushed or pulled further, thus meeting the control travel requirements of different aircraft types and flight modes.

[0041] like Figures 1 to 5 As shown, one embodiment of this application provides a throttle device applied to a flight simulator, the throttle device comprising:

[0042] The throttle base 100 includes a housing, an inwardly arranged cavity, a rotating shaft disposed within the cavity, and a through groove 110 connecting the cavity to the outside of the housing.

[0043] Throttle control lever 200, the throttle control lever 200 includes a rotating part 210 and a control lever body 220, one end of the rotating part 210 is rotatably connected to the rotating shaft, and the other end extends out from the through groove 110 and is connected to the control lever body 220;

[0044] The travel limiter 300 is detachably connected to the throttle base 100. The travel limiter 300 includes a first end 310 and a second end 320 that are disposed opposite to each other along the extending direction of the through groove 110.

[0045] The travel limiting member 300 has a limiting groove 330, which is provided at the first end 310 or the second end 320 and is recessed towards the second end 320 or the first end 310.

[0046] The throttle control lever 200 also includes a limiting part 230, which is connected to the control lever body 220;

[0047] When the control lever body 220 is rotated to a preset angle, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330.

[0048] The throttle base 100 is the main body of the flight simulator. The throttle base 100 is equipped with buttons, knobs, switches, and a joystick. The housing has a hollow structure with a cavity, within which a rotating shaft is installed. The housing also has a through slot 110. The rotating part 210 of the throttle joystick 200 is rotatably connected to the rotating shaft, allowing the user to control the joystick's rotation to control the aircraft's attitude and direction.

[0049] The travel limit component 300 is detachably connected to the throttle base 100, meaning that different travel limit components 300 can be replaced during actual use.

[0050] The first end 310 and the second end 320 of the travel limit member 300 are distributed along the extension direction of the through groove 110. The first end 310 or the second end 320 is provided with a limit groove 330. By providing the limit groove 330, the range of motion of the limit part 230 is limited, thereby limiting the rotational travel range of the throttle control lever 200. That is, when the control lever body 220 rotates to a preset angle, the limit part 230 is located in the limit groove 330. At this time, the limit part 230 is in contact with the groove wall of the limit groove 330, and the control lever body 220 cannot rotate further.

[0051] For example, the travel limiter 300 can be divided into a front section 340, a middle section 350 and a rear section 360. In some embodiments, the front section 340 corresponds to the supersonic mode, the middle section 350 corresponds to the normal flight mode, and the rear section 360 corresponds to the thrust reverser mode.

[0052] In implementation, the middle section 350 of the travel limiter 300 has a groove, meaning that the front section 340 and the rear section 360 of the travel limiter 300 are both higher than this groove. The first end 310 or the second end 320 of the travel limiter 300 is provided with a limiting groove 330. For example, taking the first end 310 corresponding to the front section 340 as an example, and the second end 320 corresponding to the rear section 360 as an example, if the limiting groove 330 is provided in the front section 340, when the throttle control lever 200 is pushed to the front section 340, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330, so that the throttle control lever 200 cannot be pushed forward further, thus preventing the aircraft from entering the supersonic mode of the front section 340. Similarly, taking the limit groove 330 located in the rear section 360 as an example, when the throttle control lever 200 is pulled back to the rear section 360, the limit part 230 is located in the limit groove 330 and contacts the groove wall of the limit groove 330, so that the throttle control lever 200 cannot be pulled back further, thus preventing the aircraft from entering the rear section 360 reverse thrust mode.

[0053] For example, taking the middle section 350 and the front section 340 of the travel limit member 300 as an example, that is, the rear section 360 of the travel limit member 300 is higher than the groove, and the rear section 360 is provided with a limiting groove 330. When the throttle control stick 200 is pushed in the middle section 350 range, the aircraft corresponds to the normal flight mode. When the throttle control stick 200 is pushed further into the front section 340, the aircraft enters the supersonic mode of the front section 340. When the throttle control stick 200 is pulled back to the rear section 360, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330, so that the throttle control stick 200 cannot be pulled back further, thus preventing the aircraft from entering the reverse thrust mode of the rear section 360.

[0054] For example, taking the middle section 350 and the rear section 360 of the travel limit member 300 as an example, that is, the front section 340 of the travel limit member 300 is higher than the groove, and the front section 340 is provided with a limiting groove 330. When the throttle control stick 200 is pushed in the middle section 350 range, the aircraft corresponds to the normal flight mode. When the throttle control stick 200 is pushed further to the front section 340, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330, so that the throttle control stick 200 cannot be pushed forward, thus preventing the aircraft from entering the supersonic mode of the front section 340. When the throttle control stick 200 is pulled back to enter the rear section 360, the aircraft enters the reverse thrust mode of the rear section 360.

[0055] It should be noted that the division of the aforementioned limiting member into a front section 340, a middle section 350, and a rear section 360, and the corresponding flight modes for each section, are illustrative examples of embodiments of this application, and not specific limitations thereof. In other embodiments, the limiting member may be divided into other numbers of sections, and each section may correspond to different modes, without limitation.

[0056] The throttle device provided in this application includes a throttle base 100, which includes a housing with an inwardly arranged cavity. A rotating shaft is disposed within the cavity. The housing has a through groove 110 connecting the cavity to the outside of the housing. A throttle lever 200 includes a rotating part 210 and a lever body 220. One end of the rotating part 210 is rotatably connected to the rotating shaft, and the other end extends from the through groove 110 and is connected to the lever body 220. A travel limiter 300 is detachably connected to the throttle base 100. The stroke limiting member 300 includes a first end 310 and a second end 320 disposed opposite to each other along the extending direction of the through groove 110; the stroke limiting member 300 has a limiting groove 330, the limiting groove 330 is disposed at the first end 310 or the second end 320, and is recessed towards the second end 320 or the first end 310; the throttle control lever 200 also includes a limiting part 230, the limiting part 230 is connected to the control lever body 220; when the control lever body 220 rotates to a preset angle, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330. With the above settings, the travel limiter 300 is detachably connected to the throttle base 100. The corresponding travel limiter 300 can be selected and installed on the throttle base 100 according to the aircraft type and flight mode. The travel limiter 300 has a limit groove 330. When the control stick body 220 of the throttle control stick 200 is rotated to a preset angle, the limit part 230 on the throttle control stick 200 will contact the groove wall of the limit groove 330, so that the throttle control stick 200 cannot be pushed or pulled further, thus meeting the control travel requirements of different aircraft types and flight modes.

[0057] In some embodiments, the travel limit member 300 is recessed into the throttle base 100 on one side surface near the throttle base 100.

[0058] In implementation, the side surface of the travel limiter 300 closest to the throttle base 100, i.e. the bottom surface of the travel limiter 300, is designed to be concave towards the throttle base 100. Since the housing part of the throttle base 100 with the through groove 110 is an upwardly convex arc-shaped housing, by designing the bottom surface of the travel limiter 300 to be concave towards the throttle base 100, the bottom surface of the travel limiter 300 can fit snugly against the arc-shaped housing part of the throttle base 100, making the connection more reliable.

[0059] In some embodiments, the central axis of the travel limit member 300 on the side surface near the throttle base 100 coincides with the rotation axis of the rotating part 210.

[0060] The limiting part 230 is mounted on the control lever body 220. When the control lever body 220 rotates, it will drive the limiting part 230 to make an arc-shaped movement. At the same time, since the central axis of the side surface of the travel limiting member 300 near the throttle base 100 coincides with the rotation axis of the rotating part 210, the arc-shaped movement trajectory of the side surface of the travel limiting member 300 near the throttle base 100 coincides with that of the limiting part 230, which allows the limiting part 230 and the travel limiting member 300 to cooperate better.

[0061] In some embodiments, the limiting groove 330 is an arc-shaped groove, and the radius of the limiting groove 330 is less than or equal to the arc radius of the side surface of the travel limiting member 300 near the throttle base 100.

[0062] In implementation, the surface of the travel limiter 300 near the throttle base 100 is arc-shaped, with a radius of r1 and a radius of r2 for the arc-shaped groove, where r1 > r2. Figure 5 As shown, this allows the limiting part 230 to better engage with the arc-shaped groove, preventing the limiting part 230 from sliding out of the arc-shaped groove and improving the limiting reliability of the stroke limiting member 300.

[0063] In some embodiments, the travel limiting member 300 has a locking portion 370 at one end along the extending direction of the through groove 110, away from the limiting groove 330. The thickness of the locking portion 370 is greater than the thickness of the adjacent position of the locking portion 370 on the side close to the limiting groove 330.

[0064] In practice, the locking part 370 is a protruding structure that extends from one side of the limiting groove 330 away from the throttle base 100. When the user pushes the throttle control lever 200 so that the limiting part 230 contacts the locking part 370, the throttle control lever 200 cannot be pushed further under the restriction of the locking part 370, thereby providing the user with mechanical feedback and improving the user experience.

[0065] In some embodiments, the locking portion 370 has a point of maximum thickness, and the absolute value of the thickness change rate of the point of maximum thickness toward the side closer to the limiting groove 330 is greater than the absolute value of the thickness change rate of the side farther away from the limiting groove 330.

[0066] In the direction from the side near the limiting groove 330 to the side away from the limiting groove 330, the locking part 370 first extends rapidly away from the throttle base 100 until the point of maximum thickness, and then extends slowly towards the throttle base 100. That is, the absolute value of the thickness change rate from the point of maximum thickness towards the side near the limiting groove 330 is greater than the absolute value of the thickness change rate from the point of maximum thickness towards the side away from the limiting groove 330, so that the locking part 370 transitions smoothly to produce a mechanical feel and a good user experience.

[0067] In some embodiments, the distance from one end of the limiting groove 330 away from the throttle base 100 to the end near the throttle base 100 is greater than the thickness of the locking portion 370.

[0068] The end of the limiting groove 330 furthest from the throttle base 100 is the highest point of the limiting groove 330, and the end of the limiting groove 330 closest to the throttle base 100 is the lowest point of the limiting groove 330. The line connecting the highest and lowest points of the limiting groove 330 extends in a direction that intersects the rotation axis of the rotating part 210. The distance between the highest and lowest points of the limiting groove 330 is the thickness of the limiting groove 330. Figure 5 As shown, a1 represents the thickness of the limiting groove 330. Similarly, the thickness of the locking part 370 is the distance between the maximum and minimum thickness points of the locking part 370. The extension direction of the line connecting the maximum and minimum thickness points of the locking part 370 intersects the rotation axis of the rotating part 210, as shown. Figure 5 As shown, a2 represents the thickness of the locking part 370, and a1 > a2. By designing the thickness of the limiting groove 330 to be greater than the thickness of the locking part 370, when the control lever body 220 rotates to a preset angle, the limiting groove 330 can better restrict the limiting part 230, while ensuring that the limiting part 230 is not blocked by the locking part 370 when it comes into contact with the locking part 370, thereby restricting the rotation of the control lever body 220.

[0069] In some embodiments, the throttle base 100 is provided with a positioning groove 120, and the width of the travel limit member 300 on the side close to the throttle base 100 is greater than the width of the travel limit member 300 on the side away from the throttle base 100; the width of the positioning groove 120 gradually increases in the direction away from the throttle base 100.

[0070] The width of the travel limiter 300 on the side closest to the throttle base 100 is the width of its bottom surface. Similarly, the width of the travel limiter 300 on the side furthest from the throttle base 100 is the width of its top surface. The widths of the bottom and top surfaces of the travel limiter 300 refer to the widths along the extension direction perpendicular to the through groove 110. Through this design, the longitudinal section of the travel limiter 300 along the extension direction of the through groove 110 is made into a shape that is larger at the top and smaller at the bottom. Simultaneously, the positioning groove 120 is designed with a structure where the groove width gradually increases from the opening to the bottom. This makes it less likely for the travel limiter 300 to fall off after being installed in the positioning groove 120, improving installation stability and reliability.

[0071] In some embodiments, the throttle base 100 is provided with a first magnetic attractor, and the travel limiting member 300 is provided with a second magnetic attractor that magnetically engages with the first magnetic attractor; and / or

[0072] A snap-fit ​​assembly is provided on the throttle base 100, which is used to fix the travel limit member 300 on the throttle base 100.

[0073] During implementation, the travel limit component 300 and the throttle base 100 can be connected by magnetic attraction, or the travel limit component 300 can be locked onto the throttle base 100 by a snap-fit ​​assembly. The installation method is simple and reliable.

[0074] It should be noted that the installation method between the travel limiter 300 and the throttle base 100 described above is an illustrative example of the embodiments of this application, and not a specific limitation of this application. In some other embodiments, other installation methods may also be used, such as providing a threaded hole 410 on the throttle base 100, and installing the travel limiter 300 onto the throttle base 100 by engaging a screw 420 with the threaded hole 410, without limitation.

[0075] Secondly, this application also provides a flight simulator, including the throttle device as described above.

[0076] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the structure and implementation principle of the flight simulator described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments, and will not be repeated here.

The housing has a through groove 110 connecting the cavity to the outside of the housing. A throttle lever 200 includes a rotating part 210 and a lever body 220. One end of the rotating part 210 is rotatably connected to the rotating shaft, and the other end extends from the through groove 110 and is connected to the lever body 220. A travel limiter 300 is detachably connected to the throttle base 100. The stroke limiting member 300 includes a first end 310 and a second end 320 disposed opposite to each other along the extending direction of the through groove 110; the stroke limiting member 300 has a limiting groove 330, the limiting groove 330 is disposed at the first end 310 or the second end 320, and is recessed towards the second end 320 or the first end 310; the throttle control lever 200 also includes a limiting part 230, the limiting part 230 is connected to the control lever body 220; when the control lever body 220 rotates to a preset angle, the limiting part 230 is located in the limiting groove 330 and contacts the groove wall of the limiting groove 330. With the above settings, the travel limiter 300 is detachably connected to the throttle base 100. The corresponding travel limiter 300 can be selected and installed on the throttle base 100 according to the aircraft type and flight mode. The travel limiter 300 has a limit groove 330. When the control stick body 220 of the throttle control stick 200 is rotated to a preset angle, the limit part 230 on the throttle control stick 200 will contact the groove wall of the limit groove 330, so that the throttle control stick 200 cannot be pushed or pulled further, thus meeting the control travel requirements of different aircraft types and flight modes.
