Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1 and 2, an embodiment of the present invention provides a throttle control device for a vertical take-off and landing aircraft, which is used for controlling the throttle opening of the vertical take-off and landing aircraft to meet the requirement of switching the throttle adjustment between a fixed-wing mode and a rotor mode of the aircraft. The vertical take-off and landing aircraft accelerator control device comprises: a housing 1; the fixed wing operating mechanism 2 comprises a slide rail 21 and a handle 22 which is slidably mounted on the slide rail 21, the slide rail 21 is fixed on the shell 1, a clamping boss 211 is arranged on the slide rail 21, and the slide rail 21 is divided into a first half rail 212 and a second half rail 213 by the clamping boss 211; rotor operating mechanism, including knob 3 and the latch device that the transmission is connected, knob 3 rotates and installs on handle 22, and latch device installs in handle 22, and knob 3 can drive the latch device joint and be fixed in slide rail 21.

The VTOL aircraft throttle control has a fixed wing control mode and a rotor control mode. When the handle 22 is arranged in the first half rail, the clamping device is not fixed with the sliding rail 21, the handle 22 can slide along the first half rail, the accelerator control device of the vertical take-off and landing aircraft is in a fixed wing control mode, and the sliding distance of the handle 22 on the sliding rail 21 is in direct proportion to the accelerator opening of the aircraft. When the handle 22 is arranged in the second half rail, the clamping device is fixed on the sliding rail 21, at the moment, the accelerator control device of the VTOL aircraft is in a rotor wing control mode, and the torque applied on the rotation of the knob 3 is in direct proportion to the opening degree of the accelerator.

The accelerator control device for the VTOL aircraft provided by the embodiment divides the slide rail 21 into the first half rail 212 and the second half rail 213, and the control modes in different slide rail sections are different, so that the device is convenient for a driver to distinguish and is simple to operate. The clamping device can effectively prevent misoperation of a driver and improve safety.

Specifically, as shown in fig. 1, a rectangular opening 11 is formed in the upper surface of the housing 1, the opening 11 faces the slide rail 21, and the upper half of the handle 22 extends out of the upper surface of the housing 1 through the opening 11. The handle 22 comprises a handle link 221 and a handle grip 222 connected with each other, and the handle grip 222 and a part of the handle link 221 are extended out of the housing 1 to facilitate gripping. The lower end of the handle link 221 is provided with a sliding slot 2211, and the sliding rail 21 is slidably mounted in the sliding slot 2211.

Optionally, at least two sliding rails 21 are arranged in parallel to increase the stability of the handle 22 sliding along the sliding rails 21. Preferably, two slide rails 21 are arranged in parallel, and both ends of the two slide rails 21 are fixed to the housing 1. Correspondingly, the lower end of the handle 22 is provided with two sliding slots 2211 in parallel, and the two sliding rails 21 are respectively slidably mounted in the two sliding slots 2211.

The fixed wing operating mechanism 2 further comprises a distance sensor, the distance sensor is arranged on the sliding rail 21 or the handle 22 or on the sliding rail 21 or the handle 22, and the installation mode of the distance sensor can be set according to the selected model. The vertical take-off and landing aircraft related in the embodiment is internally provided with the throttle control mechanism, and the throttle control mechanism directly controls the throttle opening. The distance sensor is electrically connected with the throttle control mechanism and is used for detecting the sliding distance of the handle 22 along the sliding rail 21 and transmitting a distance signal to the throttle control mechanism so as to control the throttle opening. The sliding distance of the handle 22 along the first half rail 212 is proportional to the throttle opening, i.e., the distance of the handle 22 along the first half rail 212 away from the detent boss 211 is proportional to the throttle opening.

The fixed wing control mechanism 2 further comprises a damping device, the damping device is arranged between the slide rail 21 and the handle 22 and used for increasing the resistance of the handle 22 to the movement of the slide rail 21, preventing the handle 22 from sliding too fast to cause the abrupt change of the opening degree of the accelerator, improving the flight stability and safety of the airplane, and simultaneously conforming to the habit of a driver and reducing the control burden.

The rotor wing control mechanism further comprises a force sensor which is arranged in the handle 22 and connected with the knob 3, and the force sensor is electrically connected with the throttle control mechanism. The force sensor is used for detecting the torque applied on the knob 3, converting a torque signal into a force signal and further transmitting the force signal to the throttle control mechanism so as to control the throttle opening. The torque applied to the knob 3 is proportional to the throttle opening.

The knob 3 can rotate clockwise and anticlockwise from the initial position, and the throttle opening degree of the knob 3 at the initial position is the initial value, and the aircraft keeps the hovering state. Two rotation directions of the knob 3 respectively correspond to the increase and the decrease of the accelerator opening degree, if the knob 3 rotates clockwise to correspond to the increase of the accelerator opening degree, the knob 3 rotates anticlockwise to correspond to the decrease of the accelerator opening degree, or the rotation directions and the accelerator opening degree can be changed, and the relationship between the rotation directions of the knob 3 and the increase and decrease of the accelerator opening degree can be set according to the driving requirement. Taking the clockwise rotation of the knob 3 corresponding to the increase of the opening degree of the accelerator as an example, because the torque applied to the knob has positive and negative directionality, when the knob 3 rotates clockwise, the applied torque value is positive, the opening degree of the accelerator is increased, the airplane ascends, and when the knob 3 rotates counterclockwise, the applied torque value is negative, the opening degree of the accelerator is reduced, and the airplane descends.

Further, the rotor wing control mechanism further comprises a knob centering device, wherein the knob centering device comprises an elastic restoring piece, and two ends of the elastic restoring piece are fixedly connected with the handle 22 and the knob 3 respectively. The knob centering device is used for returning the rotated knob 3 to the initial position so that the airplane can hover. The knob 3 is provided with an idle stroke of ± 1 ° with respect to its initial position, and the accelerator opening degree is kept constant during the idle stroke.

In this embodiment, latch device includes button and the mounting of transmission connection, and button and mounting are all installed in handle 22, and the button is connected with knob 3 and can be pressed by knob 3, and the mounting sets up in the outside of slide rail 21, and when pressing the button through knob 3, the mounting is fixed with slide rail 21 joint, presses the button once more, and the mounting breaks away from the contact with slide rail 21. The above-described structure of the latch device facilitates flexible switching between a fixed wing operating mode and a rotor wing operating mode.

The accelerator control device of the vertical take-off and landing aircraft provided by the embodiment of the invention also comprises a decoupling module, wherein the decoupling module is electrically connected with the distance sensor, the force sensor and the accelerator control mechanism, and the mode work of the decoupling module is as follows: disconnecting the force sensor from the throttle control mechanism when the handle 22 is in the first half rail 212; the distance sensor is disconnected from the throttle control mechanism when the handle 22 is in the second half rail 213. The decoupling module is an electrical module, and may be a centralized or distributed controller, for example, the decoupling module may be a single-chip microcomputer or may be composed of a plurality of distributed single-chip microcomputers, and a control program may be run in the single-chip microcomputers to control the operation of each component.
