DETAILED DESCRIPTION
[0034] The following further explains this patent with reference to the accompanying drawings. However, the scope of protection of this patent is not limited to specific implementation methods. Example 1
[0035] The utility model provides a posture-adjustable target plate device, which comprises a target surface 1, a scribed target surface 5, a target surface support rod, a height adjustment mechanism 2, an orientation adjustment mechanism 3, a scale 4, a ring 6, a movable base 7, and a leveling bubble 8.
[0036] Among them, the movable base 7 includes an adjusting foot 42 and a base substrate 43, and a circular hole is set in the center of the base substrate 43; the adjusting foot 42 includes four support rods with adjustment feet, which are set and fixed at the four corners of the base substrate; the ring 6 is set in the circular hole and can rotate along the circular hole; the ring 6 is fixed together with the semicircular arc plate at the front end of the Y-shaped fixing plate 31 fixed on the azimuth adjustment mechanism 3.
[0037] Four targets are positioned within the main body of target surface 1. The lower end of the main body rests on the lifting block of height adjustment mechanism 2, which adjusts the height of the main body 1. The four targets within the main body are a left HUD target, a right HUD target, an infrared target, and a low-light target. These targets are screen-printed onto target surface 1. The main body of the four targets consists of a 300mm long and 30mm wide crosshair, with three evenly spaced 30mm long and 3mm wide thin lines extending from the ends.
[0038] The height adjustment mechanism 2 includes a lifting bracket, a lifting block, and a power mechanism. The lifting bracket supports the lifting block and power mechanism. The lower end of the lifting bracket is fixed to the Y-shaped fixing plate 31 of the azimuth adjustment mechanism 3. The power mechanism can be a pulley structure, a capstan, or a screw structure. The power mechanism drives the lifting block up and down along the lifting bracket. In this way, the height of the target surface can be adjusted vertically by the height adjustment mechanism 2, and the rotation of the target surface can be adjusted by the azimuth adjustment mechanism 3.
[0039] The azimuth adjustment mechanism 3 includes a Y-shaped fixed plate 31, left and right adjustment handles 32, left and right lead screws 33, left and right thread hole seats 34, and a movable top block 35; the Y-shaped fixed plate 31 includes two semicircular arc plates at the front end, a connecting plate in the middle, and a fixed part at the rear end; the fixed part is connected to the movable top block 35; the adjustment handle 32 is fixed to one end of the lead screw 33, and after the lead screw 33 passes through the thread hole set in the middle of the thread hole seat 34, the other end of the lead screw 33 can push the movable top block 35 to move.
[0040] The scale 4 is arranged at the edge of the target surface 1 and fixed on the target surface 1 by screws; the zero position of the scale 4 is flush with the vertical center line of the target surface 1.
[0041] There are two leveling bubbles 8 , which are arranged on the base substrate 43 of the base 7 along directions parallel to the target surface 1 and perpendicular to the target surface 1 .
[0042] The size of the rectangular scribed target surface body of the scribed target surface is smaller than the corresponding size of the target surface body, and the lower frame of the scribed target surface body is directly or indirectly fixed to the Y-shaped fixing plate 31 of the azimuth adjustment mechanism 3.
[0043] The height of the target surface 1 is determined by the height adjustment mechanism 2 and the scale 4 to realize the height adjustment function; the ruled target surface 5 and the target surface 1 are in the same plane and can rotate around the same axis. The orientation of the target surface 1 is the same as that of the ruled target surface 5, and the orientation adjustment function is completed by the orientation adjustment mechanism 3; the position, pitch and roll attitude of the target surface 1 are determined by the leveling bubble 4 and the movable base 7 to realize the position, pitch and roll attitude adjustment functions.
[0044] The method of use is as follows: after the aircraft is leveled, the attitude-adjustable target plate device is placed in front of the aircraft. The mobile base 7 can adjust the attitude-adjustable target plate device to ensure that its relative position with the aircraft is determined. The four adjustment legs 42 of the attitude-adjustable target plate device adjust the pitch and roll of the attitude-adjustable target plate device, and the two adjustment bubbles 8 of the mobile base 7 are horizontally centered. At this time, the pitch and roll of the target surface 1 are level with the ground. The azimuth adjustment mechanism 3 can adjust the azimuth of the attitude-adjustable target plate device to ensure that the target surface 1 is perpendicular to the axis of symmetry of the aircraft. The height adjustment mechanism 2 and the scale 4 can adjust the height of the target surface 1 to ensure that its relative height with the aircraft is determined.
[0045] When the orientation of the target plate device needs to be adjusted, the left and right adjustment handles 32 of the orientation adjustment mechanism 3 are rotated, thereby driving the left and right lead screws 33 forward or backward, pushing the movable top block 35 to move left and right, thereby driving the Y-shaped fixed plate 31 to move left and right. The left and right movement of the Y-shaped fixed plate 31 can drive the ring 6 to rotate, so that the target surface 1 and the engraved target surface 5 both rotate with the center of the ring 6 as the rotation axis, thereby achieving orientation adjustment.
