The second button assembly 5 includes a plurality of second operation buttons 51, and the second button assembly 5 protrudes from the cover plate 4; the plurality of first operation buttons 21 and the plurality of second operation buttons 51 can be designed according to the functional requirements of different helicopter models. By operating the first button assembly 2 and the second button assembly 5, various different functions of the helicopter can be realized, so as to meet the driving requirements of the helicopter. The structures and designs of the first button assembly 2 and the second button assembly 5 are both the prior art and will not be elaborated here.

[0027] It also includes a night vision component 6, which is a key part for realizing the night recognition function and can realize the night vision functions of the first button component 2 and the second button component 5; specifically, it includes a first night vision light source, a second night vision light source, a first night vision mark 61, a second night vision mark 62, and a light transmissive member 63.

[0028] The first night vision light source is located inside the joystick 1 and consists of four mutually connected in series first LED lights. These LED lights are connected to the helicopter power supply through a circuit. When the power switch is turned on, the LED lights light up and emit light. The second night vision light source is located inside the mounting housing 3 and consists of two first LED lights connected in parallel. Similar to the first night vision light source, the second night vision light source is also connected to the helicopter power supply through a circuit and lights up when needed. The first LED lights and the second LED lights can both be white LED lights, and night vision green lenses are provided in the light emitting directions of the first LED lights and the second LED lights, so that the light passing through the night vision green lenses meets the requirements of NVIS Green A.

[0029] In some embodiments, the night vision component 6 includes a first night vision mark 61, a second night vision mark 62, a first night vision light source, and a second night vision light source. The first night vision mark 61 is provided on the joystick 1 and is arranged corresponding to the first button component 2. The first night vision light source is provided inside the joystick 1 and is arranged corresponding to the first night vision mark 61; the second night vision mark 62 is provided on the surface of the cover plate 4 and is arranged corresponding to the second button component 5. The second night vision light source is provided inside the mounting housing 3 and is arranged corresponding to the second night vision mark 62.

[0030] In some embodiments, a first night vision mark 61 is correspondingly provided for each of the plurality of first operation buttons 21, and a second night vision mark 62 is correspondingly provided for each of the plurality of second operation buttons 51.

[0031] In some embodiments, both the cover plate 4 and the joystick 1 are made of light guide plate materials to facilitate the penetration of light. The night vision component 6 further includes a light transmissive member 63. The light transmissive member 63 is provided on both the cover plate 4 and the joystick 1. For the specific structure, reference can be made to Figure 3 Taking the structure of the light transmissive member 63 on the joystick 1 as an example; the light transmissive member 63 includes a non-light white paint layer 631. Both the cover plate 4 and the joystick 1 are surrounded by the non-light white paint layer 631 as the basic layer for light propagation; a black non-light paint layer 632 is provided outside the non-light white paint layer 631 to enhance the contrast and uniformity of light, and at the same time prevent light leakage in the un-set area, which may affect the display of the first night vision mark 61 and the second night vision mark 62 at night or under low light conditions; a black non-light photosensitive coating layer 633 is provided on the outer surface of the black non-light paint layer 632, which has certain photosensitive characteristics and can better reflect or conduct light at night or under low light conditions.

[0032] The light-transmitting member 63 further includes a plurality of first light-transmitting grooves 634 and a plurality of second light-transmitting grooves 635. The first light-transmitting grooves 634 and the second light-transmitting grooves 635 can be marked on the black matte paint layer 632 and the black matte photosensitive coating layer 633 by a laser marking machine to form a set shape. The plurality of first light-transmitting grooves 634 and the plurality of second light-transmitting grooves 635 are correspondingly arranged with the plurality of first night vision markings 61 and the plurality of second night vision markings 62. The first light-transmitting grooves 634 penetrate through the black matte paint layer 632, and the second light-transmitting grooves 635 penetrate through the black matte paint layer 632 and the black matte photosensitive coating layer 633. The light emitted by the first night vision light source and the second night vision light source passes through the first light-transmitting grooves 634 and the second light-transmitting grooves 635, and then the first night vision markings 61 and the second night vision markings 62 in corresponding shapes are presented. The light is guided by the joystick 1 made of a light guide plate material and the light-transmitting member 63 and irradiates the first night vision markings 61 and the second night vision markings 62, making them clearly visible at night, thereby realizing its night vision function.

[0033] In some embodiments, the first night vision marking 61 includes a first night vision character and a first night vision circle. The first night vision circle can be arranged around the first operation button 21, and the first night vision character can be arranged above or below the first night vision circle to improve recognition. The second night vision marking 62 includes a second night vision character and a second night vision circle. The second night vision character is arranged inside the second night vision circle to improve recognition. The second night vision marking 62 can be arranged on one side of the second operation button 51, so that when the joystick 1 is held, the second night vision marking 62 is exposed in the unheld area, thereby improving recognition.

[0034] The specific working principle is as follows:

[0035] When flying at night or under low light conditions, the pilot can turn on the power switch of the night vision component 6. At this time, the first night vision light source and the second night vision light source are respectively turned on. Through the guidance of the joystick 1 made of a light guide plate material, the cover plate 4 and the light-transmitting member 63, the light is evenly irradiated on the first night vision markings 61 and the second night vision markings 62. The night vision characters and the night vision circles are clearly visible under the irradiation of the light, enabling the pilot to accurately identify and operate each button in the first button assembly 2 and the second button assembly 5, thereby ensuring the safety and operation accuracy of night flight.
