Description
Technical Field
The present invention relates to a structural design of an aircraft, particularly a large civil aircraft, and particularly to a design of a mounting structure for a head-up display of an aircraft.
Background
A head-up display is a display device on an aircraft that projects the primary flight parameters onto the helmet or front display glass of the pilot. The head-up display enables a pilot to master airplane flight information while keeping a head-up state in the flight process, so that the flight safety can be remarkably improved, and the taking-off and landing capacity of the airplane under low visibility is improved. Head-up displays are now increasingly being used on civil aircraft.
In civilian aircraft, the head-up display is mounted on the top of the cockpit, in the overhead position of the pilot, by a mounting structure. To ensure that its display function is performed optimally, the head-up display needs to be calibrated during the manufacturing and installation of the aircraft. The calibration of the head-up display includes mechanical calibration and electrical calibration, wherein the mechanical calibration is performed by a mounting structure of the head-up display. The mounting structure not only can perform the functions of mounting and supporting the head-up display during the mounting process of the head-up display, but also can perform the function of mechanical axis alignment on the head-up display.
Generally, a head-up display includes a projection device and a combiner, and the projection device projects a generated image onto the combiner for display. During installation, due to manufacturing assembly errors, the projection device and the combiner need to be aligned in the axial direction with respect to the main body, and alignment between the projection device and the combiner is also required. In the existing design of the mounting structure of the head-up display of the civil aircraft, the projection device and the combiner are usually mounted and calibrated respectively. Such a solution has some drawbacks as follows:
firstly, since the projection device and the combiner are separately installed, the installation structure is complex, and the manufacturing difficulty and cost are high.
In addition, the installation and calibration of the projection device and the combiner are carried out on an airplane, the assembly requirement is high, and the installation is difficult.
Moreover, since it is necessary to perform the calibration of the projection device and the combiner with respect to the axial direction of the aircraft and the mutual calibration between the projection device and the combiner, respectively, the whole calibration process is complicated, and the calibration efficiency is low, which may affect the assembly schedule of the aircraft.
In addition, the calibration adjusting mechanism and the equipment installation interface are not completely independent, the calibration state is influenced by the disassembly, assembly and maintenance of the head-up display equipment, the head-up display equipment needs to be recalibrated after the disassembly and assembly of the head-up display equipment, and the aircraft maintenance and air route maintenance progress is influenced.
Accordingly, there is a need in the art for an improved mounting structure for a head-up display to simplify the mounting of the head-up display.
Disclosure of Invention
The present invention has been made to solve the above technical problems occurring in the prior art. An object of the present invention is to provide an improved mounting structure of a head-up display capable of simplifying mounting and alignment of respective components of the head-up display including a projection device and a combiner, improving mounting efficiency.
The head-up display mounting structure of the present invention is used for mounting a head-up display to a cabin structure of an aircraft, wherein the head-up display includes a combiner and a projection device. The head-up display mounting structure includes:
the mounting structure comprises a mounting structure main body, wherein a combiner mounting interface and a projection device mounting interface are arranged on the mounting structure main body, the combiner is fixedly mounted on the mounting structure main body through the combiner mounting interface, and the projection device is fixedly mounted on the mounting structure main body through the projection device mounting interface; and

In the above-described structure of the head-up display mounting structure, both the combiner and the projection device are fixedly mounted on the mounting structure body, and the relative positions of the combiner mounting interface for the combiner and the projection device mounting interface for the projection device are fixed, so that the relative positional accuracy between the combiner and the projection device can be ensured by controlling the manufacturing accuracy of the mounting structure body. In this way, the relative position calibration between the combiner and the projection device can be omitted when the head-up display is mounted on the aircraft. Furthermore, the mounting structure body is allowed to rotate in pitch, roll and/or yaw degrees of freedom relative to the aircraft axis, so that the alignment of the head-up display relative to the aircraft axis can be easily achieved.
In one particular configuration, three transition legs are included, including:

< integral Structure >
Fig. 1 shows a perspective view of a head-up display mounting structure 10 of the present invention, on which head-up display mounting structure 10 a combiner 1 and a projection device 2 are mounted. The head-up display mounting structure 10 includes a mounting structure body 11, the mounting structure body 11 being connected to the aircraft, for example, to a bulkhead of an aircraft cockpit, by a first transition bracket 12 and a second transition bracket 13.
It can be seen that in the structure shown in fig. 1, two first transition brackets 12 are included, which are respectively located on the left and right sides of the mounting structure body 11, and the mounting structure body 11 is adjustably connected to the first transition brackets 12 located on the left and right sides by a left adjusting bolt group 20 and a right adjusting bolt group 30, respectively. The second transition bracket 13 is located at the front side of the mounting structure body 11, and the mounting structure body 11 is adjustably connected with the second transition bracket 13 through the front adjusting bolt group 40.
Fig. 2a and 2b show a top perspective view of the mounting structural body 11 from above, showing the left and right adjustment bolt sets 20 and 30 mounted on the left and right sides of the mounting structural body 11 and the front adjustment bolt set 40 mounted on the front side of the mounting structural body 11. The left and right adjusting bolt sets 20 and 30 are connected to the mounting structure body 11 through left and right adjusting bolt set mounting interfaces 21 and 31 on the left and right sides of the mounting structure body 11, and the front adjusting bolt set 40 is connected to the mounting structure body 11 through a front adjusting bolt set mounting interface 41 on the front side of the mounting structure body 11. The specific structure of the left, right and front set of adjustment bolts 20, 30, 40 will be described in detail below.
Fig. 3a and 3b show a bottom perspective view of the mounting structure body 11 from below, showing the combination unit mounting interface 50 and the projection device mounting interface 60 provided on the underside of the mounting structure body 11 for mounting the combination unit 1 and the projection device 2 to the mounting structure body 11. A combiner mounting hole 51, a combiner positioning pin mounting point 52, a projector mounting hole 61, and a projector positioning pin mounting point 62 are provided on the lower surface of the mounting structure body 11 for providing connection members such as positioning pins, bosses, and the like to fix the combiner 1 and the projector 2. The specific structure of the combiner mounting interface 50 and the projection device mounting interface 60 will be described in detail below.
The specific structure of each component of the head-up display mounting structure 10 will be described below.
< left and right set of adjusting bolts >
Fig. 4a and 4b show the structure of the left adjustment bolt group 20 for connecting the mounting structure body 11 to the first transition bracket 12 located on the left side. The structure of the right adjustment bolt group 30 is the same as that of the left adjustment bolt group 20, and a description thereof will not be repeated.
The left set of adjustment bolts 20 includes a first bolt 22, which first bolt 22 extends through a left set of adjustment bolt mounting interface 21 provided on the left side of the mounting structure body 11. Nuts 23 are provided on the upper and lower sides of the left adjusting bolt group attaching interface 21, respectively, to be engaged with the first bolts 22. Preferably, a first washer 24 is also provided between the nut 23 and the left adjusting bolt set mounting interface 21. The first washer 24 is preferably a spherical washer to prevent play and angles between the nut 23 and the mounting structure body 11 due to non-engagement after the mounting structure body 11 is rotated.
As can be seen more clearly in fig. 4b, at least two nuts 23 and at least two first washers 24 are included, respectively above and below the mounting structure body 11. In this way, after being adjusted in position, the position of the mounting structure body 11 relative to the first bolt 22 can be effectively locked.
The upper portion of the first bolt 22 is connected to the first transition bracket 12. Preferably, a second washer 25 is provided at the location where the first bolt 22 is connected to the first transition bracket 12. Also, a slotted nut 26 and a pin 27 are provided on the first bolt 22 to lock the connection between the first bolt 22 and the first transition bracket 12.
In the above structure, the nut 23 can be adjusted to move the mounting structure body 11, or the left adjusting bolt group mounting interface 21, in the up-down direction by a certain range with respect to the first bolt 22. The first bolt 22 is connected to the first transition bracket 12 in a relatively fixed position. In this way, this up-and-down movement of the mounting structure body 11 relative to the first bolt 22 will be translated into a rotation of the mounting structure body 11 in both pitch and roll degrees of freedom relative to the first transition bracket 12 and thus relative to the axis of the aircraft. The range of rotation of the mounting structure body 11 in both the pitch and roll degrees of freedom resulting from adjustment of the nut 23 is preferably ± 1 °. After adjustment, the position of the first bolt 22 relative to the mounting structure body 11 may be locked by means of a fuse cooperating with the nut 23, preferably by means of a fuse cooperating with the nut 23, as shown in fig. 4a and 4 b. Thus, in the preferred construction shown in the drawings, three nuts 23 are included, one above the left set of jack bolts mounting interface 21 and two below the left set of jack bolts mounting interface 21.
As described above, two nuts 23 and two first washers 24 are preferably provided, respectively above and below the mounting structure body 11, to achieve positional adjustment of the mounting structure body 11 relative to the first bolt 22 and locking after adjustment into position. Alternatively, a greater number of nuts 23 may be provided as desired.
In addition, although not preferred, only one nut 23 may be provided, such as the nut 23 located below the mounting structure body 11 in the drawings, which functions as an adjustment member, and after adjustment into place, the position of the nut 23 relative to the first bolt 22 is fixed by a member such as a fuse. This is also within the scope of the invention.
Furthermore, other locking means than slotted nut 26 with pin 27, nut 23 with fuse, etc. may be used, and it is within the scope of the present invention to lock the relative position between the first bolt 22 and the mounting structure body 11 and the first transition bracket 12 by welding, etc., for example, after calibration is complete.
< set of front adjusting bolts >
Fig. 5a and 5b illustrate an exemplary configuration of the front set of adjustment bolts 40 for attaching the mounting structure body 11 to the second transition bracket 13.
The front adjusting bolt set 40 includes a second bolt 42, and the second bolt 42 passes through the connecting hole on the second transition bracket 13 and the front adjusting bolt set mounting interface 41 on the mounting structure main body 11 to adjustably connect the mounting structure main body 11 and the second transition bracket 13 together. A ball socket 44, which is composed of two ball socket halves and in which a ball shaft 43 is arranged, is fixedly mounted in the front adjusting screw assembly mounting socket 41. The second bolt 42 extends through the ball axle 43 so that the second bolt 42 can rotate with the ball axle 43 about a sphere within the socket 44. The second bolt 42 is locked relative to the second transition bracket 13 by means of a washer, slotted nut, pin or the like, thereby locking the connection between the mounting structure body 11 and the second transition bracket 13 and preventing them from accidentally disengaging from each other. Each half of the socket 44 is fixedly connected to the front set bolt mounting interface 41 of the mounting structure body 11 by a fastening structure such as three screws and nuts and washers engaged therewith.
As can be seen more clearly in fig. 5b, a certain clearance 45 is left between the second bolt 42 and the ball axle 43 and the socket 44 to allow the second bolt 42 together with the ball axle 43 to be rotated in relation to the socket 44 in three degrees of freedom pitch, roll and yaw, preferably in the range of ± 1 °.
In addition to the ball and socket arrangement shown in the figures, the forward adjustment bolt set 40 may also take other forms of attachment arrangement, such as a standard ball bearing form, a cardan ball shaft form, etc., and remain within the scope of this invention.
< Assembler installation interface >
Fig. 6 shows a partially enlarged view of the instrument mounting interface 50 provided on the lower side of the mounting structure body 11.
The combiner mounting interface 50 includes a combiner locating circular pin 53 and a combiner locating diamond pin 54 mounted in a combiner locating pin mounting point 52, and further includes at least one combiner screw 55 disposed in the combiner mounting hole 51 (four combiner screws 55 on four corners are shown). These connecting members fix the combiner 1 to the mounting structure body 11 in a relatively fixed position.
Those skilled in the art will appreciate that the components of the combiner mounting interface 50 may be added, removed, or modified according to actual needs, as long as the combiner 1 can be fixedly mounted on the mounting structure body 11.
< projector mounting interface >
Fig. 7 shows a partially enlarged view of the projection device mounting interface 60 provided on the lower side of the mounting structure body 11.
The projection device mounting interface 60 includes projection device positioning round pins 63 and projection device positioning diamond pins 64 mounted in the projection device positioning pin mounting points 62, and further includes at least one projection device screw 65 (four projection device screw 65 on four corners are shown) disposed in the projection device mounting holes 61. By the configuration of the projection device mounting interface 60, the projection device 2 can be mounted to the mounting structure body 11 in a fixed position.
Similar to the combiner mounting interface 50, the components of the projection device mounting interface 60 may be added, removed or modified according to actual needs, as long as the projection device 2 can be fixedly mounted on the mounting structure body 11.
< calibration method >
The mounting and calibration method of the head-up display mounting structure 10 of the present invention will be specifically described below.
First, the combiner 1 is fixedly attached to the combiner attachment interface 50 of the head-up display attachment structure 10, and the projector 2 is fixedly attached to the projector attachment interface 60 of the head-up display attachment structure 10.
One first transition bracket 12 is connected to the left and right sides of the mounting structure body 11 by left and right adjusting bolt groups 20 and 30, respectively, and the first transition bracket 12 is connected to a structure of the nacelle such as a bulkhead.
The mounting structure body 11 is connected with the second transition bracket 13 by the front adjusting bolt group 40, and the second transition bracket 13 is connected to the bulkhead of the nacelle.
In the head-up display mounting structure 10 of the above-described structure, the positions and orientations of the combination machine 1 and the projection apparatus 2 mounted on the head-up display mounting structure 10 are fixed, and therefore, by controlling the manufacturing structural accuracy of the head-up display mounting structure 10, particularly the mounting structure body 11 thereof, it is possible to achieve the relative positional accuracy requirement between the combination machine 1 and the projection apparatus 2, and achieve the alignment between the combination machine 1 and the projection apparatus 2. Therefore, in mounting the head-up display using the head-up display mounting structure 10 of the present invention, it is allowed to omit the calibration of the mutual position between the combiner 1 and the projection apparatus 2.
Subsequently, the combiner 1 and the projection device 2 are calibrated with respect to the aircraft axis. This calibration is performed by adjusting the nuts 23 on the left and right set of adjustment bolts 20, 30. Specifically, the adjustment nut 23 allows the mounting structure body 11 to move in the up-down direction relative to the first bolt 22 of the left adjustment bolt group 20 and the first bolt of the right adjustment bolt group 30, thereby allowing the mounting structure body 11 to rotate in the pitch and/or roll degrees of freedom, during which the ball shaft 43 of the front adjustment bolt group 40 rotates relative to the ball socket 44. Wherein, when the direction and amount of movement of the first bolt 22 of the left set of adjustment bolts 20 and the first bolt of the right set of adjustment bolts 30 are the same, the mounting structure body 11 will rotate in the pitch degree of freedom. When the first bolt 22 of the left adjustment bolt set 20 and the first bolt of the right adjustment bolt set 30 move in opposite directions and in the same amount, the mounting structural body 11 will rotate in the roll degree of freedom. And when the amounts of movement of the first bolt 22 of the left adjustment bolt group 20 and the first bolt of the right adjustment bolt group 30 are different, the mounting structural body 11 will rotate in two degrees of freedom, pitch and roll.
In addition, preferably, as shown in fig. 8, the first transition bracket 12 on both left and right sides of the mounting structure body 11 is further provided with oblong holes 14, and the left and right adjustment bolt groups 20 and 30 can be positionally adjusted along the oblong holes 14, thereby allowing the head-up display mounting structure 10 to be rotated in yaw freedom.
Thus, in the preferred configuration shown in the figures, the mounting structure body 11 is allowed to rotate in all three degrees of freedom pitch, roll and yaw, thereby allowing for omnidirectional alignment of the mounting structure body 11.
