[0048] Combine the following Figure 1-Figure 14 The throttle lever assembly and the flight control device of the present invention are described. It can be understood that the aircraft throttle platform is a control device for controlling the engine thrust, which is installed on the central control panel of the aircraft cockpit. The central control panel usually contains many important flight control systems, communication equipment, navigation equipment and other control panels and interfaces of the flight management system. The throttle platform includes a platform body and a throttle lever assembly, etc. The throttle lever assembly is moved forward to increase the engine thrust, and the throttle lever assembly is pulled back to reduce the engine thrust.

[0049] It should also be noted that when the aircraft is in normal flight, the throttle provides positive thrust; when the aircraft is landing, the throttle provides reverse thrust.

[0050] Reference Figures 1 to 3 as well as Figures 10 to 14 As shown, the throttle lever assembly according to the embodiment of the present invention includes a guide member 100, a rotating member 200 and an operating mechanism 300, wherein the guide member 100 is used to be fixedly connected to the platform body of the aircraft throttle platform, the rotating member 200 is used to be rotatably connected to the platform body of the aircraft throttle platform, the operating mechanism 300 includes a fixed member 310, a control member 320 and a handle member 330, the fixed member 310 is fixedly connected to the rotating member 200, the control member 320 is slidably connected to the fixed member 310 up and down, the control member 320 is slidably connected to the guide member 100 front and back, and the guide member 100 is provided with a first operating area 110 and a second operating area 120 for guiding the movement of the control member 320, the handle member 330 is configured to be slidable up and down, the handle member 330 is slidably connected to the guide member 100 front and back, and the guide member 100 is provided with a third operating area 130 and a fourth operating area 140 for guiding the movement of the handle member 330;

[0051] Among them, a locking structure is provided between the operating member 320 and the fixing member 310, and the locking structure has an unlocked state and a locked state; when the locking structure is in the unlocked state, the operating member 320 moves up and down relative to the fixing member 310; when the locking structure is in the locked state, the operating member 320 is fixed relative to the fixing member 310; when the locking structure is in the unlocked state, the operating member 320 moves forward and backward relative to the first operating area 110, the handle member 330 moves forward and backward relative to the third operating area 130, and the operating mechanism 300 can perform a forward pushing action; when the locking structure is in the locked state, the operating member 320 moves forward and backward relative to the second operating area 120, the handle member 330 moves forward and backward relative to the fourth operating area 140, and the operating mechanism 300 can perform a reverse pushing action.

[0052] The throttle lever assembly provided by the present invention cooperates with the operating mechanism 300 and the locking structure. When the locking structure is in the unlocked state, the operating mechanism 300 can push forward, the operating member 320 can move forward and backward relative to the first operating area 110, and the handle member 330 can move forward and backward relative to the third operating area 130 to adjust the magnitude of the forward thrust; when the locking structure is in the locked state, the operating mechanism 300 can push backward, the operating member 320 can move forward and backward relative to the second operating area 120, and the handle member 330 can move forward and backward relative to the fourth operating area 140 to adjust the magnitude of the reverse thrust. When the forward thrust changes to reverse thrust, or from reverse thrust to forward thrust, the pilot must judge the current flight state of the aircraft to decide whether to unlock or lock the locking structure to avoid misoperation, thereby improving the structural integrity, high operational safety, and stable and reliable.

[0053] It should be noted that, refer to Figure 1 In the embodiment of the present invention, the guide member 100 is fixedly mounted on the body of the throttle platform via the support shaft 600, and the rotating member 200 is mounted on the body of the throttle platform via the fixed shaft 700. The rotating member 200 can rotate around the center line of the fixed shaft 700. Therefore, when the operating mechanism 300 moves forward and backward, that is, during forward thrust and reverse thrust, the operating mechanism 300 drives the rotating member 200 to rotate around the fixed shaft 700 under the guidance of the guide member 100.

[0054] Specifically, Figure 2 , Figure 3 , Figures 7 to 9In the embodiment of the present invention, the operating member 320 includes a sliding plate 321 and a lever head 322. The sliding plate 321 is connected to the fixed member 310 in an up-and-down sliding manner. One end of the sliding plate 321 is connected to the guide member 100 in a forward-and-backward sliding manner. The lever head 322 is disposed at the other end of the sliding plate 321 opposite to the sliding plate 321, and a locking structure is disposed between the fixed member 310 and the lever head 322. With the above arrangement, the operating member 320 is composed of a sliding plate 321 and a lever head 322. The sliding plate 321 is connected to the fixed member 310 and slides in the up-and-down direction. One end of the sliding plate 321 is connected to the guide member 100 in a forward-and-backward sliding manner. The locking structure is disposed between the fixed member 310 and the lever head 322, allowing the locking state to be controlled by the movement of the sliding plate 321 and the lever head 322, providing flexible control and guidance.

[0055] It is understandable that, referring to Figure 4 , Figure 5 as well as Figures 7 to 9 In the embodiment of the present invention, the locking structure includes a locking portion 311 and a pressing component 400, the locking portion 311 is provided on the fixing member 310, the pressing component 400 is slidably connected to the operating rod head 322 of the operating member 320, the locking portion 311 has a first locking position 3111 and a second locking position 3112, the pressing component 400 has a first clamping section 410 and a second clamping section 420, and the pressing component 400 has a first position and a second position relative to the operating rod head 322 of the operating member 320; when the pressing component 400 is in the first position, the first The clamping section 410 is inserted and matched with the first locking position 3111, and the first clamping section 410 can slide up and down relative to the first locking position 3111, and the locking structure is in an unlocked state; when the pressing component 400 is in the second position, the second clamping section 420 is inserted and matched with the second locking position 3112, and the second clamping section 420 is fixed relative to the second locking position 3112, and the locking structure is in a locked state; wherein, when the operating member 320 slides up and down relative to the fixing member 310, the position of the pressing component 400 can be switched between the first position and the second position.

[0056] Using the above structure, refer to Figure 7 When the pressing member 400 is located at the first position, the first holding section 410 is inserted and matched with the first locking position 3111, and the locking structure is in the unlocked state at this time. Fig.11 , the structure of the operating member 320 cooperating with the first operating area 110 moves relative to the first operating area 110, the fixing member 310 and the handle member 330 move accordingly, and the handle member 330 moves relative to the third operating area 130. At this time, when the operating mechanism 300 is in positive push, the size of the positive thrust is adjusted by reciprocating forward and backward movement of the operating mechanism 300; refer to Figure 7 and Fig.12When the pressing component 400 is located at the first position, the structure on the operating member 320 that cooperates with the first operating area 110 moves backward relative to the first operating area 110 to the limit position of the first operating area 110, and the operating rod head 322 of the operating member 320 is driven upward to slide relative to the fixing member 310, so that the structure that cooperates with the first operating area 110 of the operating member 320 is transitioned from the first operating area 110 to the second operating area 120. At this time, since the operating member 320 slides upward, it also drives the pressing component 400 to slide upward. Figure 8 and Fig. 9 Therefore, the pressing member 400 switches from the first position to the second position, the locking structure is in a locked state, the operating member 320 is fixed relative to the fixing member 310, and the handle member 330 is driven upward to slide from the third operating area 130 to the fourth operating area 140. Fig.13 and Fig.14 At this time, the operating mechanism 300 changes from forward thrust to reverse thrust, and the magnitude of the reverse thrust is adjusted by the reciprocating forward and backward movement of the operating mechanism 300. Therefore, during the pilot's operation, the change from forward thrust to reverse thrust, or from reverse thrust to forward thrust, must be determined by the pilot's judgment of the current flight state of the aircraft to determine whether to unlock or lock the limit device to avoid misoperation. The flexibility of position switching allows for rapid switching between the locked and unlocked states as needed to meet different usage requirements; by locking the relative positions between the operating member 320, the handle member 330 and the fixing member 310, the degree of freedom and the limit range of the operating mechanism 300 can be controlled, which helps to improve the safety and stability of the throttle lever assembly and prevent accidental movement or unnecessary vibration.

[0057] It is understandable that in the embodiment of the present invention, the locking structure further includes a first elastic member, one end of which is connected to the joystick head 322 of the operating member 320, and the other end of the first elastic member is connected to the pressing member 400, and the first elastic member is used to drive the pressing member 400 to switch from the first position to the second position. Through the above arrangement, since the first elastic member is connected to the operating member 320 and the pressing member 400, when the operating member 320 slides up and down relative to the fixing member 310, the first elastic member will be subjected to a compression or extension force, thereby driving the pressing member 400 to switch from the first position to the second position, providing an automated way to achieve position switching, reducing the need for external intervention, and ensuring the stability and reliability of the locking structure; by sliding the operating member 320 up and down, the relative position between the operating member 320 and the pressing member 400 can be changed, thereby achieving the switching of the pressing member 400 between the first position and the second position, and the above design allows the pilot to freely select the locking and unlocking states as needed, providing greater flexibility.

[0058] Specifically, refer to Figure 4In the embodiment of the present invention, the joystick head 322 includes a first rod head 3221 and a second rod head 3222. The first rod head 3221 and the second rod head 3222 are connected by screws to form the joystick head 322. An unlocking button component is installed inside the second rod head 3222, and a first elastic component is installed inside the first rod head 3221. The combination of the button component and the first elastic component can realize the pressing and rebounding of the button component.

[0059] Specifically, refer to Figure 4 In the embodiment of the present invention, the first rod head 3221 is provided with a mounting groove 32211, the second rod head 3222 is provided with a sliding groove 32221, the mounting groove 32211 of the first rod head 3221 is connected to the sliding plate 321 by screws, and the upper end of the fixing member 310 can slide up and down in the sliding groove 32221 of the second rod head 3222. Therefore, when the operating rod head 322 is lifted or pressed, the operating rod head 322 can drive the sliding plate 321 to move up and down relative to the fixing member 310, which has a simple structure, convenient operation, good stability, and low assembly cost.

[0060] Specifically, refer to Figures 3 to 9 In an embodiment of the present invention, the button component is a stepped shaft composed of cylinders of different diameters, one end of the button component is connected to the first elastic member, and the other end is equipped with a button cap, so that the button component has a first position and a second position when moving, the diameter of the first holding section 410 is smaller than the diameter of the second holding section 420, the first locking position 3111 is the first channel, the second locking position 3112 is the second channel, the first channel is connected to the second channel, and the second channel is located above the first channel, the width of the first channel is smaller than the width of the second channel, the first channel is suitable for the insertion of the first channel, the second channel is suitable for the insertion of the second holding section 420, and the diameter width of the second holding section 420 is greater than the width of the first channel.

[0061] With the above structure, when the pressing component 400 is in the first position, the first holding section 410 is located in the first hole and can slide up and down relative to the first hole, and the second holding section 420 abuts against the outside of the first hole, so that the pressing component 400 is kept in the first position; when the joystick head 322 is pulled upward, the pressing component 400 slides upward to the second hole corresponding to the second holding section 420, and the pressing component 400 is elastically driven by the first elastic member, so that the second holding section 420 is inserted into the second hole. At this time, due to the large diameter width of the second holding section 420 Due to the width of the first hole, the second holding section 420 is fixed at the second hole and cannot slide toward the first hole. Therefore, the pressing component 400 is in the second position, and the pilot cannot press down the joystick head 322. It can be understood that the joystick head 322 is in a high position; only by pressing the pressing component 400 inward so that the first holding section 410 faces the first hole, can the joystick head 322 be pressed downward so that the first holding section 410 is inserted into the first hole, and the pressing component 400 returns to the first position. At this time, it can be understood that the joystick head 322 is in a low position.

[0062] It should be noted that the above-mentioned first elastic member is a cylindrical spring. Of course, in other embodiments, the above-mentioned first elastic member can also be an elastic pad, an elastic sheet, etc.; the diameter of the first holding section 410 is 3mm, the diameter of the second holding section 420 is 5mm, the width of the first channel is 3.5mm, and the width of the second channel is 5.5mm; the pressing component 400 is also provided with a limiting section 430 located on one side of the second holding section 420, and the limiting section 430 is used to limit the moving stroke of the pressing component 400 and prevent the pressing component 400 from being separated from the joystick head 322.

[0063] It should also be noted that, in some embodiments, the set positions of the above-mentioned locking portion 311 and the pressing component 400 can be interchanged; or, the above-mentioned locking structure can also include a locking pin and a pin channel, and the pin channel has a plurality of insertion positioning portions to limit the position of the locking pin, and the locking pin is adjusted to cooperate with the plurality of insertion positioning portions through relative movement with the pin channel, thereby limiting the up and down position of the operating member 320; or the locking structure can be set as a rotating mechanism, and the rotating mechanism is used to rotate and limit the up and down position of the operating member 320, and the structure of the locking structure can be set to limit the up and down position of the operating member 320, and no limitation is made here.

[0064] It is understandable that, referring to Figure 1 , Figures 10 to 14In the embodiment of the present invention, the first operating area 110 is a first guide slot provided in the guide member 100, and the second operating area 120 is a second guide slot provided in the guide member 100.

[0065] It should be noted that, in the embodiment of the present invention, the above-mentioned first sliding part 3211 is a first limiting shaft, and the first limiting shaft is connected to the sliding plate 321 by bolts. Of course, in some embodiments, the above-mentioned first sliding part 3211 can also be a first protruding column integrally formed with the sliding plate 321.

[0067] Specifically, refer to Figure 2 and Figure 3In an embodiment of the present invention, a second elastic member 500 is provided between the rotating member 200 and the handle member 330, one end of the second elastic member 500 is connected to the rotating member 200, and the other end of the second elastic member 500 is connected to the handle member 330, and the second elastic member 500 is used to drive the handle member 330 to reset to the position where the second sliding portion 331 is located in the third guide groove. During forward pushing, the second sliding portion 331 is located in the third guide slot, and the operating mechanism 300 can adjust the magnitude of the forward thrust; during reverse pushing, the second sliding portion 331 is pulled upward by the handle piece 330, so that the second sliding portion 331 transitions from the third guide slot to the fourth guide slot, and the operating mechanism 300 can adjust the magnitude of the reverse thrust; therefore, when switching from reverse pushing to forward pushing, when the second sliding portion 331 slides to the position corresponding to the third guide slot, the second sliding portion 331 is driven by the second elastic member 500 to slide to the third guide slot, and the handle piece 330 slides downward, thereby entering forward pushing, and the automatic resetting function of the handle piece 330 is realized through the elastic force, ensuring that the handle piece 330 is always located at the specified position, with a simple structure and convenient operation.

[0068] It should be noted that the above-mentioned first elastic member is a tension spring. Of course, in other embodiments, the above-mentioned second elastic member 500 can also be an elastic pad, an elastic sheet, etc.; the first guide channel and the second guide channel are spaced apart in the up and down directions, so when the handle 330 and the sliding plate 321 move, they are isolated from each other to ensure the reliability of transmission; the above-mentioned first guide groove, the second guide groove, the third guide groove and the fourth guide groove are all arc-shaped, so as to facilitate the smooth rotation of the operating mechanism 300; of course, in some embodiments, the first operating area 110, the second operating area 120, the third operating area 130 and the fourth operating area 140 can also be set as arc-shaped grooves.

[0069] It should also be noted that, in the present embodiment, the second sliding portion 331 is a second limiting shaft, and the second limiting shaft is connected to the handle piece 330 via bolts. Of course, in some embodiments, the second sliding portion 331 may also be a second protruding column integrally formed with the handle piece 330 .

[0070] It is understandable that, referring to Figures 1 to 3 as well as Figure 6In the embodiment of the present invention, the handle 330 is arranged between the sliding plate 321 of the operating member 320 and the fixed member 310, the fixed member 310 is provided with a limiting slide groove 312 and a first channel 313, and the sliding plate 321 of the operating member 320 is provided with a second channel; the handle 330 can be installed in the limiting slide groove 312 in an upward and downward manner, and the handle 330 is provided with a handle rod head 332, one end of the handle rod head 332 can be slidably arranged in the first channel 313, and the other end can be slidably arranged in the second channel. Through the above arrangement, the main part of the handle 330 is arranged in the chamber formed between the sliding plate 321 of the operating member 320 and the fixed member 310, which plays a role of protection and stable sliding; at the same time, the position and sliding of the handle 330 can be easily controlled by the pilot through the handle rod head 332 by hand, so as to realize the corresponding operation and control, and the limiting slide groove 312 on the fixed member 310 limits the sliding range and movement direction of the handle 330 in the vertical direction. The handle piece 330 can only slide up and down in the limiting slide groove 312, thereby ensuring that the handle rod head 332 moves within a specific range; one end of the handle rod head 332 is inserted into the first channel 313, and the other end is inserted into the second channel. The above design enables the handle rod head 332 to slide freely in the vertical direction and cooperate with the first channel 313 and the second channel to provide more stable and accurate operation control.

[0071] Specifically, in this embodiment, a receiving groove is provided on the joystick head 322. When the handle piece 330 slides upward through the handle rod head 332, the handle rod head 332 can be received in the receiving groove, which is not only convenient for the pilot to operate, but also strengthens the positioning and fixing of the handle piece 330 through the cooperation of the joystick head 322, the sliding plate 321 and the fixing piece 310, and makes reasonable use of the space.

[0072] It should be noted that, in some embodiments, the handle member 330 can also be slidably disposed outside the cavity formed between the sliding plate 321 and the fixing member 310, for example, the handle member 330 is slidably disposed on the side of the sliding plate 321 facing away from the fixing member 310, or the handle member 330 is slidably disposed on the side of the fixing member 310 facing away from the sliding plate 321, which is not limited here.

[0073] Specifically, refer to Figures 1 to 3 In this embodiment, the sliding plate 321 is provided with two long holes 3213, and the fixing member 310 is connected with two sliding bolts 800. The sliding bolts 800 match the long holes 3213 one by one. The sliding bolts 800 pass through the long holes 3213 and extend out of the long holes 3213. Therefore, the sliding plate 321 can move up and down along the long holes 3213 relative to the fixing member 310; the number of the long holes 3213 is not limited here.

[0074] It should also be noted that, in the present embodiment, the rotating member 200 is a disc body, a mounting recess is provided on the side wall of the disc body, one end of the fixing member 310 is inserted into the mounting recess, and is fixedly connected to the disc body by a plurality of mounting bolts, with a simple structure, low manufacturing cost and difficulty, and high production efficiency.

[0075] It is understandable that, referring to Figure 1 In the embodiment of the present invention, the guide member 100, the rotating member 200 and the operating mechanism 300 are each in two groups, and the guide member 100, the rotating member 200 and the operating mechanism 300 are matched one by one, and a locking structure is provided between the fixed member 310 and the operating member 320 in each group of the operating mechanism 300; wherein the movements of the two groups of locking structures are independent of each other. With the above structure, when the throttle lever assembly is arranged, the guide member 100, the rotating member 200 and the operating mechanism 300 are provided on both the left and right sides of the fixed shaft 700, and the two locking structures are independently controlled without interfering with each other, so that the limiting or limiting release of the individual operating mechanism 300 can be realized.

[0076] It should be noted that, in the present embodiment, the two groups of guide members 100 are fixedly connected to the body of the throttle platform, and therefore, the two groups of guide members 100 are configured as an integrated structure. Of course, a split structure may also be configured, which is not limited here.

[0077] It is understandable that in the embodiment of the present invention, the flight control device includes the above-mentioned throttle lever assembly, and the flight control device can be a simulation device used in the pilot training process, or a flight control device on an aircraft. The flight control device includes the above-mentioned throttle lever assembly, and the throttle lever is limited and released in the mechanical structure through the cooperation of the handle 330 and the locking structure on the throttle lever assembly, which can simulate the operation of the throttle lever of a real aircraft, and is stable and reliable; the structure is compact, does not involve the internal transmission of the throttle platform, is simple to install, convenient to maintain and adjust, and has low cost.

[0078] It can be understood that, in the embodiment of the present invention, the operation process of the throttle lever assembly is as follows:

[0079] Reference Fig.11 When the aircraft is in normal flight, that is, when the throttle is in positive thrust, the first sliding portion 3211 (first limit axis) of the sliding plate 321 and the second sliding portion 331 (second limit axis) of the handle member 330 slide in the first operating area 110 (first guide groove) and the third operating area 130 (third guide groove) respectively.

[0080] Reference Fig.12 and Fig.13When the pilot wants to switch from forward thrust to reverse thrust, he needs to move the operating mechanism 300 backward first, and then pull the joystick head 322 upward. The joystick head 322 drives the sliding plate 321 upward, so that the first sliding portion 3211 of the sliding plate 321 transitions from the first operating area 110 to the second operating area 120 (the second guide groove). At this time, due to the upward pulling of the joystick head 322, the pressing component 400 inside the joystick head 322 pops out. At this time, the joystick head 322 is in a high position state, and because the pressing component 400 is in a popped-out state, the joystick head 322 cannot be pressed down.

[0081] Because the first sliding portion 3211 of the sliding plate 321 is at the front end of the second guide slot, the operating mechanism 300 cannot be pushed forward, and the second sliding portion 331 of the handle 330 is at the rear end of the third guide slot, so the operating mechanism 300 cannot be pushed backward. At this time, the operating mechanism 300 is in a locked state. The pilot must judge the current flight state of the aircraft to avoid misoperation before taking the next step.

[0082] Reference Fig.13 and Fig.14 When it is confirmed that the reverse thrust is to be turned on, the handle rod head 332 of the handle member 330 is pulled upward, and the handle member 330 drives the second sliding portion 331 to transition from the third guide groove to the fourth operating area 140 (the fourth guide groove). At this time, the operating mechanism 300 can adjust the magnitude of the reverse thrust.

[0083] When the pilot wants to switch from reverse thrust to forward thrust, he needs to push the operating mechanism 300 forward first. Under the action of the second elastic member 500, the handle 330 automatically transitions from the fourth guide slot to the third guide slot. Because the first sliding portion 3211 of the sliding plate 321 is at the front end of the second guide slot, the operating mechanism 300 cannot be pushed forward. The second sliding portion 331 of the handle 330 is at the rear end of the third guide slot. Therefore, the operating mechanism 300 cannot be pushed backward. At this time, the operating mechanism 300 is in a locked state. At this time, the pilot must judge the current flight status of the aircraft to avoid misoperation before proceeding to the next step.

[0084] After confirmation, it is determined that the transition from reverse thrust to forward thrust is to be made. The pilot needs to press the pressing component 400 first. At this time, the joystick head 322 is pressed downward. The joystick head 322 moves downward and drives the sliding plate 321 to slide downward. The sliding plate 321 drives the first sliding part 3211 to transition from the second guide groove to the first guide groove. At this time, the operating mechanism 300 can adjust the magnitude of the forward thrust.

[0085] 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
