Description

Technical Field

[0001] The invention relates to the technical field of flight simulation, and in particular to a mounting mechanism of a head-up display and a mounting method of the head-up display. Background Art

[0002] The Head Up Display (HUD) is a flight assistance instrument on a spacecraft. Its main function is to project important flight-related information, such as the flight direction icon, onto the pilot's eye point, so that the pilot can easily combine the forward visual scene with the information displayed by the HUD, thereby reducing the frequency of the pilot looking down to check the information and avoiding interruptions in attention.

[0003] However, in the field of aerospace flight technology, the installation of traditional head-up displays is ensured by precision equipment of the whole machine factory, which is not only costly but also time-consuming, and therefore not suitable for direct use in the head-up display simulation application of flight simulators. On the contrary, if the installation position of the head-up display is set arbitrarily, or the installation position deviates from the target position during the installation of the head-up display, the position / angle of the flight direction icon and the flight view will be offset, thus affecting the normal training and testing of pilots.

[0004] In order to overcome the above-mentioned defects of the prior art, there is an urgent need in the art for a head-up display installation technology for quickly and cheaply positioning the head-up display at the correct position in the full-motion simulator cockpit to meet the normal training and testing needs of pilots.

[0024] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Such relative terms are only used for the convenience of description and do not mean that the device described therein must be manufactured or operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0027] It is understood that although the terms "first", "second", "third", etc. may be used herein to describe various components, regions, layers and / or parts, these components, regions, layers and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers and / or parts. Therefore, the first component, region, layer and / or part discussed below may be referred to as a second component, region, layer and / or part without departing from some embodiments of the present invention.

[0028] As mentioned above, in the field of aerospace flight technology, the installation of traditional head-up displays is ensured by precision equipment of the whole machine factory, which is not only costly but also time-consuming, and therefore not suitable for direct use in the head-up display simulation application of flight simulators. On the contrary, if the installation position of the head-up display is set arbitrarily, or the installation position deviates from the target position during the installation of the head-up display, the position / angle of the flight direction icon and the flight view will be offset, thereby affecting the normal training and testing of pilots.

[0029] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mounting mechanism for a head-up display and a method for mounting a head-up display, which can quickly and cheaply position the head-up display to the correct position in the cockpit of a full-motion simulator to meet the normal training and testing needs of pilots.

[0030] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a mounting mechanism for a head-up display provided in some embodiments of the present invention is shown.

[0031] like Figure 1As shown, in some embodiments of the present invention, the mounting mechanism of the head-up display includes a base 7, a roll axis adjustment mechanism 3, a pitch axis adjustment mechanism 2, and a HUD mounting seat 1. The base 1 is fixedly connected to a first position inside the cabin of the simulator. The roll axis adjustment mechanism is used to adjust the roll axis angle of the HUD mounting seat 1. The pitch axis adjustment mechanism 2 is used to adjust the pitch axis angle of the HUD mounting seat 1. The HUD mounting seat 1 is connected to the base 7 via the roll axis adjustment mechanism 3 and the pitch axis adjustment mechanism 2, and has a first interface 11 fixedly connected to the theodolite, and a second interface 12 fixedly connected to the head-up display. The theodolite can be installed on the HUD mounting seat 1 via the first interface 11 and face the view screen of the simulator to indicate the roll axis angle difference and the pitch axis angle difference between the current position of the head-up display and the target position.

[0032] By configuring the roll axis adjustment mechanism 3, the pitch axis adjustment mechanism 2, and the first interface 11 fixedly connected to the theodolite, the present invention can adjust the roll axis adjustment mechanism 3 according to the roll axis angle difference indicated by the theodolite, and adjust the pitch axis adjustment mechanism 2 according to the pitch axis angle difference indicated by the theodolite, so that the head-up display installed on the second interface 12 of the HUD mounting seat 1 can be positioned at a correct position in the full-motion simulator cockpit at low cost and quickly, thereby meeting the normal training and testing needs of pilots.

[0033] Further, in Figure 1 In the illustrated embodiment, the installation mechanism of the head-up display may also be preferably provided with a translation adjustment mechanism, including but not limited to one or more of an X-axis adjustment mechanism 4, a Y-axis adjustment mechanism 5, and a Z-axis adjustment mechanism 6, which are respectively used to adjust the translation position of the HUD mounting seat 1 in the X-axis direction, the Y-axis direction, and / or the Z-axis direction of the simulator cabin. The HUD mounting seat 1 may also be connected to the base 7 via the one or more translation adjustment mechanisms. In this way, the present invention also supports translational adjustment of the position of the head-up display from the X-axis direction, the Y-axis direction, and / or the Z-axis direction of the simulator cabin, so that the head-up display can be positioned at the correct position in the full-motion simulator cockpit at low cost and quickly, thereby meeting the normal training and testing needs of the pilot.

[0034] Furthermore, in some embodiments of the present invention, the mounting mechanism of the head-up display may also be preferably equipped with a theodolite. The theodolite may be mounted on the HUD mounting base 1 via the first interface 11 and face the calibration reference mark of the visual screen of the simulator, so as to indicate the roll axis angle difference, pitch axis angle difference, X-axis difference, Y-axis difference and / or Z-axis difference between the current position of the head-up display and the target position via the deviation between its cross mark and the calibration reference mark.

[0035] In addition, in some embodiments of the present invention, the mounting mechanism of the head-up display may also preferably include a fixing mechanism of a hard structure such as a mounting rod or a support frame. The first end of the fixing mechanism may be connected to the second position inside the cabin of the simulator, and the second end thereof may be connected to the fourth position of the head-up display at the target position. Later, when the technician disassembles the second interface 12 of the mounting mechanism from the third position of the head-up display, the fixing mechanism may replace Figure 1 The multi-degree-of-freedom mounting mechanism shown in the figure fixes the head-up display at the target position. In this way, the mounting mechanism provided by the present invention has higher reusability on the one hand, and the head-up display can be repeatedly installed on multiple simulators, thereby further reducing the installation cost of the head-up display. On the other hand, by using a fixing mechanism with a hard structure such as a mounting rod and a support frame to replace Figure 1 The multi-degree-of-freedom mounting mechanism shown in the present invention has higher reliability and will not cause the displacement and / or deflection of the head-up display mounting position due to one or more of the pitch axis adjustment mechanism 2, roll axis adjustment mechanism 3, X-axis adjustment mechanism 4, Y-axis adjustment mechanism 5, and Z-axis adjustment mechanism 6 being affected by external forces.

[0036] Further, Figure 1 The first position where the multi-degree-of-freedom mounting mechanism is connected to the simulator cabin should be different from the second position where the fixing mechanism is connected to the simulator cabin, so as to meet the requirement of connecting both at the same time to realize the connection relationship conversion of the head-up display at the target position. In some embodiments of the present invention, in order to avoid structural damage to the simulator cabin by the additional opening, the first position can be selected from the fixing threaded hole of the driver's seat inside the cabin of the simulator, and the second position can be selected from the HUD mounting hole on the top surface of the cabin above the driver's seat.

[0037] The working principle of the above-mentioned installation mechanism will be described below in conjunction with some embodiments of the installation method. Those skilled in the art will understand that these embodiments of the installation method are only some non-limiting implementation methods provided by the present invention, and are intended to clearly demonstrate the main concept of the present invention and provide some specific solutions that are convenient for the public to implement, rather than to limit all functions or all working methods of the installation mechanism. Similarly, the installation mechanism is also only a non-limiting implementation method provided by the present invention, and does not constitute a limitation on the execution subject or object of each step in these installation methods.

[0038] Please refer to Figure 2 , Figure 2 A schematic flow chart of a method for installing a head-up display provided in some embodiments of the present invention is shown.

[0039] like Figure 2As shown, during the installation of the head-up display, the installer may first fix the base 7 of the mounting mechanism to a first position inside the cabin of the simulator. In some non-limiting embodiments, the base 7 may be connected to the HUD mounting seat 1 via angle adjustment mechanisms such as the pitch axis adjustment mechanism 2 and the roll axis adjustment mechanism 3, and / or translation adjustment mechanisms such as the X-axis adjustment mechanism 4, the Y-axis adjustment mechanism 5, and the Z-axis adjustment mechanism 6. The first position may preferably be a fixed threaded hole of the driver's seat inside the cabin of the simulator.

[0040] Please refer to Figure 3A and Figure 3B , Figure 3A and Figure 3B A schematic diagram showing a first position provided in some embodiments of the present invention.

[0041] like Figure 3A and Figure 3B As shown, during the installation of the head-up display, the installer can first remove the driver seats 31 and 32 in the simulator cabin to expose the fixing threaded holes 33 below them. Afterwards, the installer can fix the base 7 of the mounting mechanism to the floor of the cabin through the fixing threaded holes 33. In this way, the present invention can meet the connection relationship conversion requirements of the head-up display at the target position, thereby achieving the effect of replacing the multi-degree-of-freedom mounting mechanism with a low-cost, stable fixing mechanism, and on the other hand, it can avoid making additional holes in the cabin and avoid structural damage to the simulator cabin.

[0042] like Figure 2 As shown, after the base 7 of the mounting mechanism is fixedly connected to the first position inside the cabin of the simulator, the installer can fix the theodolite installation to the first interface 11 of the HUD mounting seat 1 and point it toward the vision screen of the simulator to indicate the position difference and / or angle difference between the current position of the head-up display and the target position.

[0043] Specifically, in the process of determining the roll axis angle difference and pitch axis angle difference between the current position of the head-up display and the target position, the installer can first turn on the calibration reference function of the simulator vision system to display the calibration reference mark (e.g., a cross mark) on the vision screen. Afterwards, the installer can observe the calibration reference mark through the theodolite, and determine the position differences such as the X-axis difference, Y-axis difference, and Z-axis difference, and / or the angle differences such as the roll axis angle difference and the pitch axis angle difference between the current position of the head-up display and the target position according to the position deviation and / or angle deviation between the cross mark of the theodolite and the calibration reference mark.

[0044] Further, after determining the position difference and / or angle difference between the current position of the head-up display and the target position, the installer may adjust one or more of the X-axis adjustment mechanism 4, the Y-axis adjustment mechanism 5, and the Z-axis adjustment mechanism 6 accordingly according to the translation position differences such as the X-axis difference, the Y-axis difference, and the Z-axis difference, so that the center of the cross mark of the theodolite coincides with the calibration reference mark on the vision screen, thereby ensuring that the current position of the head-up display coincides with the target position in the X-direction degree of freedom, the Y-direction degree of freedom, and the Z-direction degree of freedom.

[0045] Afterwards, the installer may further adjust the roll axis adjustment mechanism 3 according to the roll axis angle difference, and / or adjust the pitch axis adjustment mechanism 2 according to the pitch axis angle difference, so that the longitude and latitude of the cross mark of the theodolite coincide with the longitude and latitude of the calibration reference mark, respectively, thereby further ensuring that the rotational freedom in the pitch direction and the rotational freedom in the roll direction of the current position of the head-up display coincide with the target position.

[0046] like Figure 2 As shown, after the target position of the head-up display is determined, the installer can install the head-up display to the target position via the second interface 12 of the HUD mounting base 1. Further, in order to ensure the accuracy and reliability of the installation position, after completing the installation operation of the head-up display, the installer can also observe the calibration reference mark on the visual screen through the theodolite to verify whether the spatial position of the bracket mounting base has been adjusted to the right position.

[0047] Furthermore, in order to reduce the installation cost of the head-up display and improve the reliability of the installation position of the head-up display, after installing the third position of the head-up display to the second interface 12 of the HUD mounting seat 1, the installer may also preferably connect the first end of the fixing mechanism of a hard structure such as a mounting rod or a support frame to the second position inside the cabin of the simulator, and connect its second end to the fourth position of the head-up display located at the target position, so as to achieve a fixed connection between the head-up display and the cabin of the simulator. Here, the second position includes but is not limited to the HUD mounting hole on the top surface of the cabin above the driver's seat. Afterwards, the installer can release the connection between the third position of the head-up display and the second interface 12 of the HUD mounting seat 1, and remove Figure 1 The multi-degree-of-freedom mounting mechanism shown in the figure is used to fix the head-up display at the target position by the fixing mechanism. After that, the installer can also install the driver seats 31 and 32 to the fixing threaded holes 33 after removing the multi-degree-of-freedom mounting mechanism, thereby restoring the original state of the simulator cabin and reusing the fixing threaded holes 33 used to install the multi-degree-of-freedom mounting mechanism.

[0048] By adopting the installation scheme of the connection relationship transfer, the above-mentioned installation mechanism provided by the present invention has higher reusability on the one hand, and the head-up display can be repeatedly installed on multiple simulators, thereby further reducing the installation cost of the head-up display. On the other hand, by adopting a fixing mechanism of a hard structure such as a mounting rod and a support frame to replace Figure 1 The multi-degree-of-freedom mounting mechanism shown in the present invention has higher reliability and will not cause the displacement and / or deflection of the head-up display mounting position due to one or more of the pitch axis adjustment mechanism 2, roll axis adjustment mechanism 3, X-axis adjustment mechanism 4, Y-axis adjustment mechanism 5, and Z-axis adjustment mechanism 6 being affected by external forces.

[0049] Please refer to further Figure 4 , Figure 4 A schematic diagram of an interface for heads-up display information provided in some embodiments of the present invention is shown.

[0050] like Figure 4 As shown, after the head-up display is fixed to the target position aligned with the driver's eye point of the vision system, the vision system of the simulator can display the flight simulation vision 41 such as the sky and the ground on the vision screen during the flight simulation. At the same time, the head-up display can display flight direction icons 42, wing icons and other flight related information on the vision screen during the flight simulation. Therefore, compared with the traditional vehicle-mounted HUD, which only needs to be installed in an approximate range to project data on any position of the windshield, the present invention aligns and adjusts the installation position and installation angle of the head-up display according to the driver's eye point position of the vision system to achieve the linkage between the simulator HUD data and the vision screen, thereby providing accurate and reliable reference information such as flight direction, pitch axis angle, roll axis angle, etc. for flight training.

[0051] Although the above methods are illustrated and described as a series of actions for simplicity of explanation, it should be understood and appreciated that these methods are not limited by the order of the actions, because according to one or more embodiments, some actions may occur in a different order and / or concurrently with other actions from those illustrated and described herein or not illustrated and described herein but understandable to those skilled in the art.

[0052] The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of the disclosure.
