Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Please refer to the following first. Figure 1 The composite thrust control rod model includes a housing 1, a thrust rod assembly 2 pivotally connected to the housing 1, a thrust reverser assembly 3 pivotally connected to the thrust rod assembly 2, and angle sensors for acquiring the input stroke of the thrust rod assembly 2 and the thrust reverser assembly 3, respectively. It should be noted that this composite thrust control rod model can be as follows: Figure 1As shown, two thrust rod assemblies 2 and two thrust reverser assemblies 3 are arranged inside the housing 1 to simulate the thrust control stick of a twin-engine aircraft. Alternatively, one thrust rod assembly 2 and one thrust reverser assembly 3 can be arranged inside the housing 1 to simulate the thrust control stick of a single-engine aircraft. Those skilled in the art can choose according to the actual situation.
[0026] Please see Figure 2 and Figure 3 The thrust rod assembly 2 includes a thrust handle 21, a thrust rod 22, a crank 23, a first rocker arm 24, and a movable block 25. The thrust handle 21 is fixed to the upper end of the thrust rod 22. The thrust rod 22 is provided with a groove for accommodating the aforementioned reverse thrust rod assembly 3. A first support rod 11 and a second support rod 12 located on both sides of the thrust rod 22 are fixed inside the aforementioned housing 1. Figure 2 As shown, the first support rod 11 is located on the right side ( Figure 2 (in the direction of the middle), close to the housing 1, the second support rod 12 is inside the housing 1.
[0027] like Figure 2 As shown, a first pivot shaft 26 is fixed between the first support rod and the second support rod. The aforementioned crank 23 and thrust rod 22 are pivotally connected to the first pivot shaft 26. The first end of the crank 23 ( Figure 2 The left end of the crank 23 is pivotally connected to the pushrod assembly 3. The second end of the crank 23 ( Figure 2 The right end of the first rocker arm 24 is pivotally connected to the upper end of the first rocker arm 24, and the lower end of the first rocker arm 24 is pivotally connected to the movable block 25. Furthermore, the movable block 25 is also fixedly connected to the rotation shaft of the angle sensor fixed to the bottom of the housing 1. A mounting plate 27 can be provided inside the housing 1 to fix the angle sensor to the inside of the mounting plate 27.
[0028] Please see Figure 3 When pushing forward, i.e., pushing the push handle 21, the push rod 22 rotates counterclockwise around the first pivot axis 26. Figure 3 The direction of the thrust rod assembly 3 is applied to the first end of the crank 23, causing the crank 23 to rotate counterclockwise around the first pivot axis 26. This raises the second end of the crank 23, thereby driving the rotating shaft of the movable block 25 and the angle sensor to rotate via the first rocker arm 24. In this way, the angle sensor can detect the rotation angle of the movable block 25 and thus determine the input stroke of the thrust handle 21. As an example, a correspondence table between the rotation angle collected by the angle sensor and the input stroke of the thrust handle 21 can be established through repeated experiments, thereby determining the input stroke of the thrust handle 21 based on the rotation angle.
[0029] Please see Figure 4 and Figure 5The thrust reverser assembly 3 includes a thrust reverser handle 31, a thrust reverser 32, and a second rocker arm 33. The thrust reverser 32 is L-shaped and includes a first rod 321 and a second rod connected vertically. The thrust reverser handle 31 is fixed to the open end of the first rod 321. The second rod is placed in a groove in the thrust rod 22, and its open end is pivotally connected to the upper end of the thrust rod 22. As an example, the upper end of the thrust rod 22 is rotatably provided with a second pivot shaft, and the open end of the second rod is fixedly connected to this second pivot shaft. The upper end of the second rocker arm 33 is pivotally connected to the connection between the first rod 321 and the second rod of the thrust reverser 32. The lower end of the second rocker arm 33 is pivotally connected to the first end of the crank 23.
[0030] like Figure 4 As shown, during reverse thrust, i.e., when the reverse thrust handle 31 is pulled, the reverse thrust rod 32 rotates clockwise around the open end of the second rod. Figure 4 The crank 23 rotates clockwise (in the direction of rotation), thereby pulling the second rocker arm 33 upward, causing the crank 23 to rotate clockwise. This, in turn, drives the rotating shaft of the movable block 25 and the angle sensor to rotate via the first rocker arm 24. In this way, the angle sensor can detect the rotation angle of the movable block 25 and thus determine the input stroke of the reverse push handle 31.
[0031] Similarly, a correspondence table between the rotation angle collected by the angle sensor and the input stroke of the reverse push handle 31 can be established through repeated experiments, thereby determining the input stroke of the reverse push handle 31 by the rotation angle.
[0032] It should be noted that the thrust reverser assembly 3 is pivotally connected to the thrust rod 22, such that the rotation direction of the moving block 25 driven by pushing the thrust handle 21 is opposite to the rotation direction of the moving block 25 driven by pulling the thrust reverser handle 31. For example, when the thrust handle 21 is in its initial position, the angle sensor is at the reference position of 0°. After pushing the thrust handle 21, the angle sensor can detect that the rotation axis has rotated from 0° to 60°. After pulling the thrust reverser handle 31, the angle sensor can detect that the rotation axis has rotated from 0° to -30°. In this way, since the angle signals received by the angle sensor are different during forward and reverse thrust, even if a single angle sensor is used to collect the input strokes of forward and reverse thrust, there will be no confusion. The thrust signal is output based on the input strokes of forward and reverse thrust, improving the reliability of the model.
[0033] Furthermore, to avoid mixed input of forward and reverse thrust, the composite thrust control lever model of this invention also includes a locking component, allowing the forward and reverse thrust functions to operate independently. Specifically, the locking component is used to restrict the relative rotation between the second rocker arm 33 and the reverse thrust rod 32 when the thrust handle 21 is pushed, so that the composite thrust control lever model conforms to the actual thrust control principle during operation, that is, locking the reverse thrust rod 32 when the thrust rod 22 is operated, thereby improving the rationality and reliability of the model.
[0034] Specifically, such as Figure 6 and Figure 7 As shown, the locking assembly includes a first cam 41, a locking link 42, a limiting link 43, and a slide groove 44. The first cam 41 is located on the side of the push rod 22 facing the second support rod 12 and is fixedly connected to the second pivot shaft. When the reverse push handle 31 is pulled, the second rod will drive the first cam 41 to rotate synchronously. The lower end of the limiting link 43 is pivotally connected to the lug 121 of the second support rod 12, and the upper end of the limiting link 43 is pivotally connected to the lower end of the locking link 42. The upper end of the locking link 42 is configured to fit the outer edge of the first cam 41. The slide groove is fixed to the push rod 22, and the locking link 42 slidably passes through the slide groove.
[0035] like Figure 6 As shown, when the thrust handle 21 is in the initial position, the locking link 42 is separated from the first cam 41, releasing the lock from the reverse thrust rod 32, so that the reverse thrust rod 32 can be pulled in this state to perform a reverse thrust operation.
[0036] like Figure 7 As shown, when the push handle 21 is pushed, the push rod 22 rotates clockwise around the first pivot axis 26. Figure 7 In the direction of rotation, the limiting link 43 supports the locking link 42 upward, so that the locking link 42 slides relative to the slide groove 44, and the upper end of the locking link 42 can engage with the first cam, thereby locking the push rod 32.
[0037] In this way, the composite thrust control rod model of this utility model can not only simulate the operation process of the thrust rod 22 and the reverse thrust rod 32, but also lock the reverse thrust rod 32 when the thrust rod 22 is operated, which conforms to the working principle of the actual thrust control rod, improves the rationality and reliability of the model, and thus improves the teaching or demonstration effect.
[0038] Revisit Figure 2 The composite thrust control rod model of this utility model is also equipped with a fault indication component, including a second cam 51 disposed on the side of the thrust rod 22 facing the first support rod 11 and a limit switch 52. The second cam 51 is fixedly connected to the aforementioned second pivot shaft. The limit switch 52 is fixedly mounted on the thrust rod 22.
[0039] When the reverse push handle 31 is pulled, the reverse push rod 32 will drive the second cam 51 to rotate synchronously. When the second cam 51 touches the limit switch 52, it indicates that the second cam 51 has rotated to the maximum angle, which can limit the continued operation of the reverse push handle 31.
[0040] The fault indication component may also include alarm devices such as buzzers and indicator lights. The aforementioned angle sensor, limit switch 52, and alarm device can communicate with the controller included in the model. Specifically, when the controller receives a gradually increasing positive rotation angle transmitted from the angle sensor, it indicates a forward push operation. If the limit switch 52 closes at this time, it indicates that the reverse push rod 32 is pulled during the forward push. Next, the controller activates the alarm device to warn of an abnormality in the locking component.
[0041] The aforementioned controller can be an MCU (Microcontroller Unit), a PLC (Programmable Logic Controller), a DSP (Digital Signal Processor), etc.
[0042] Furthermore, the total stroke of the thrust rod 22 can be divided into multiple segments, corresponding to the slow speed, climbing speed, and takeoff speed, respectively. Three indicator lights are also installed on the housing 1 to correspond to these three speeds. When the rotation angle collected by the angle sensor is transmitted to the controller, the controller determines the input stroke based on the rotation angle, determines the current segment based on the input stroke, determines the corresponding speed, and finally controls the corresponding indicator light to illuminate.
[0043] Furthermore, the composite thrust control lever model of this invention can also be linked with an engine model. Specifically, the engine model may include a housing with thrust reverser function and a fan installed inside the housing, thereby simulating the control of the forward and reverse thrust of an aircraft engine. The controller can communicate with the fan. The fan control switch can be installed on the housing of this invention. When controlling the engine model through the composite thrust control lever model of this invention, the control switch is first turned on to power the fan. Next, the thrust lever or thrust reverser is operated. After the controller acquires the input stroke of the thrust lever or thrust reverser, it outputs a thrust signal and controls the direction and speed of the fan rotation, as well as the relevant thrust reverser device on the engine model, thereby adapting to the operation of the thrust lever or thrust reverser and better demonstrating the acceleration control of the thrust lever or thrust reverser. In addition, the controller can also acquire the feedback signal of the fan speed and compare it with the speed corresponding to the thrust signal to avoid errors.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
