Detailed implementation mode

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] As Figure 1 shown, a multi-limit flipable throttle platform control mechanism for a ground station includes a throttle handle rotating arm 1, a box body 2, a master control switch 3, a parking trigger 4, a flipping link mechanism 5, a first limit block 6, a second limit block 7, a damping adjustment nut 8, an acquisition potentiometer 9, etc. Its characteristics are: the multi-limit flipable throttle platform provides 5 gear position limits and a flip gear shifting function, and the acquisition potentiometer outputs voltages corresponding to the front and back rotation positions.

[0023] As Figures 1 - 8 shown, the throttle handle rotating arm 1 is connected to the box body 2 through the rotating main shaft 11, and the throttle handle rotating arm 1 can rotate around the rotating main shaft 11. An arc surface is formed on the top of the box body 2, and a top groove is provided on the top arc surface. The upper end of the throttle handle rotating arm 1 extends above the top groove. A flipping link mechanism 5 is provided on the throttle handle rotating arm 1. One end of the flipping link mechanism 5 is connected to one end of the large tension spring 17, and the other end of the large tension spring 17 is connected to the outer flange of the rotating main shaft. An arc-shaped bracket is provided on the side of the box body 2. Its characteristics are that a shutdown brake limit pin 12 for shutdown brake limit is provided on the upper part of the throttle handle rotating arm. A parking trigger 4 is provided on the right side of the top of the box body. A limit groove matching with the shutdown brake limit pin 12 is provided on the parking trigger 4. The limit groove and the shutdown brake limit pin 12 cooperate to form a locking limit at the parking position. The front end surface of the parking trigger 4 forms a front stop surface, which cooperates with the shutdown brake limit pin 12 to form a limit at the idle speed position. A first limit block 6 is provided in the arc-shaped groove on the side of the box body. A gear position limit pin 15 matching with the first limit block 6 is provided on the flipping link mechanism. The gear position limit pin 15 and the right side surface of the first limit block 6 form a limit at the middle position. The gear position limit pin 15 and the left side surface of the first limit block 6 form a limit at the small boost position. A second limit block 7 is provided on the left side of the first limit block 6. The gear position limit pin 15 and the second limit block 7 form a limit at the large boost position.

[0024] According to an embodiment of the present invention, as Figure 3 shown, the throttle handle rotating arm 1 rotates along the rotating main shaft 11, and the stop brake limit pin 12 on the throttle handle rotating arm is stuck in the limit groove on the parking trigger 4 to achieve the locking and limiting of the parking position. The parking trigger 4 is rotatably connected to the bracket provided on the chassis. A parking trigger limit pin 14 is provided below the parking trigger 4. The parking trigger 4 rotates along the stop trigger rotating shaft to achieve unlocking, and a torsion spring is provided on the parking trigger 4 to achieve reset.

[0025] According to an embodiment of the present invention, as Figure 4 shown, after the parking trigger is unlocked, the throttle handle rotating arm 1 rotates to the left. After the parking trigger 4 is limited in place by the parking trigger limit pin, the stop brake limit pin on the throttle handle rotating arm leans against the front end stop surface of the parking trigger to achieve the limiting of the idle position.

[0026] According to an embodiment of the present invention, as Figure 5 shown, when the throttle handle rotating arm 1 rotates to the left, the gear limit pin 15 on the throttle handle rotating arm leans against the right end surface of the first limit block 6 to achieve the limiting of the middle position.

[0027] According to an embodiment of the present invention, as Figure 9 、 Figure 10 shown, a throttle handle body rotating shaft 16 is provided at the upper end of the throttle handle rotating arm. The throttle handle 22 is installed on the throttle handle body rotating shaft 16. The flip link structure includes an upper link 23 and a flip link coupler 24. The upper end of the upper link 23 is connected to the right end of the throttle handle body rotating shaft 16. The lower end of the upper link 23 is rotatably connected to the right end of the flip link coupler 24. The left end of the flip link coupler 24 is rotatably connected to the left side of the throttle handle rotating arm; the gear limit pin 15 is provided at the right end of the flip link coupler 24.

[0028] The throttle handle 22 can be flipped upwards by a certain angle. The lower part of the throttle handle body has a D-shaped groove, which drives the throttle handle rotating shaft to rotate. When the throttle handle rotating shaft rotates, it drives the flip link mechanism 5 and the gear limit pin 15 to move upwards (the flip link mechanism 5 also has a D-shaped surface). The large tension spring 17 provides the self-resetting function for the throttle handle body.

[0029] When the throttle handle is flipped upwards, the link mechanism drives the limit pin to be lifted upwards, and the large tension spring is stressed.

[0030] After letting go, the large tension spring pulls the link mechanism and the limit pin downwards, and the handle returns to the initial position.

[0031] When the throttle handle flips, it drives the gear position limit pin and the flip linkage clip to move upward, and pushes the throttle handle forward to cross the small afterburner block. Release the handle, and the large pull spring provides a reset force to reset the position of the throttle handle, and the limit pin enters the afterburner area. The flip linkage clip provides a limit for the flip of the throttle handle. To return from the afterburner area to the initial position, the throttle handle also needs to be flipped, and the gear position limit pin crosses the small afterburner block and enters the non-afterburner area. The purpose of flipping the throttle handle is to prevent easy afterburner operation, and a protection operation for flipping the throttle handle is required.

[0032] As Figure 6 shown is the small afterburner position. The throttle handle flips, driving the rotation of the throttle handle body rotating shaft. The throttle handle body has a D-shaped groove, thus driving the flip link mechanism 5 to act, lifting the gear position limit pin 15 above the first limit block 6. The throttle handle rotating arm continues to rotate leftward. After the gear position limit pin 15 crosses the first limit block, the flip link mechanism 5 is reset by the large pull spring 17, and the gear position limit pin 15 leans against the left end face of the first limit block to achieve the limit of the small afterburner position.

[0033] According to an embodiment of the present invention, as Figure 7 shown, the throttle handle rotating arm 1 continues to rotate leftward, and the rotating arm limit pin moves into the groove on the second limit block 7 to achieve the limit of the large afterburner position.

[0034] According to an embodiment of the present invention, as Figure 8 shown, both sides of the throttle handle rotating arm 1 are provided with friction plates. The throttle handle rotating arm 1 is fixed to the box body 2 through the rotating main shaft 11, and the damping adjustment nut 8 is used to compress the disc spring 18 to adjust the rotational damping. The acquisition potentiometer 9 is fixed on the potentiometer fixing plate 21, and the potentiometer fixing plate 21 is connected to the throttle handle rotating arm 1. When the throttle handle rotating arm 1 rotates, it drives the potentiometer fixing plate 21 to rotate, drives the shaft of the acquisition potentiometer 9 to rotate, and the acquisition potentiometer outputs the voltage corresponding to the front and back rotation positions.
