Lever anti-reflection sheet device

The present invention relates to a lever anti-reflection sheet device, in particular to a reflection sheet device used in a car head-up display, which utilizes a lever to enhance the anti-vibration effect so as not to be affected by the vibration of the car dashboard, thereby enhancing the The fixing and support stability of the reflective sheet.

There is more and more information on the car. When reading this information while driving, it is often dangerous because the line of sight is removed. In order to solve this problem, the use of the car head-up display is developed, so that the driver can read the information. It can also take into account the situation of the road ahead, especially the head-up display using the concave mirror virtual image, which can enlarge the display area and make the displayed image a certain distance from the driving eyes, usually more than two meters, which will make the driving gaze display information. At the same time, the focal length of the line of sight is close to the line of sight of the road condition, so that the driver can simultaneously consider the road condition while reading the information, and greatly reduce the risk of driving.

The principle of virtual image imaging is imaging through a concave mirror (concave mirror imaging formula: formula: 1/p+1/q=1/f; f: focal length, q: object distance, p: image distance), general magnification can make virtual image Zoom in, you can also make the virtual image distance farther from the same ratio, about four to six times, so that the reader can reach the best state, and if the magnification is too large, it will easily make the reader feel dizzy, so let the virtual image The imaging distance is more than two meters away from the driving eyeball, and the imaging needs to be more than 1.2 meters behind the reflecting sheet, that is, the optical path distance from the screen to the concave mirror is about 24 cm or more (assuming that the distance is about 24 cm). The magnification is five times); in addition, the light path can be reflected back and forth through the mirror to increase the distance, but the optical path occupies a large volume, usually inside the car dashboard, and a device for placing a head-up display .

In this way, in addition to the original car factory can reserve the required space at the time of design, in the post-installation market, the device of the head-up display is placed on the instrument panel of the car, and the volume of the optical path device is too large. It can't be placed, and it can even hinder the driver's sight.

Another way to solve the problem of excessively installing the optical path is to use a separation method to fix the display screen to the upper part of the windshield and to fix the reflection plate to the instrument panel of the car; however, the dashboard of many vehicles is easily driven by the engine or air conditioner. The rotation of the compressor generates vibration, which causes the reflector fixed above to follow the vibration, and the amplification of the concave mirror causes the displacement of the vibration to be amplified by the amplification ratio, which causes the shaking of the picture to be more serious.

In order to solve the problem of the existing reflector sloshing, the creator of the case has TW Patent Publication No. 530961, TW Patent No. M273183, TW Patent No. M375372, TW Patent Publication No. 576080, TW Patent No. I352165, TW Patent No. M288937, TW Patent Patent No. M275639 and other patents have found relevant technical content and applications. There are still technical bottlenecks in the solution of the existing reflector sloshing problem.

For the problem of swaying of the reflection piece, although the elastic force of the elastic element can be directly used, the reflection piece is pressed against the windshield to resist the vibration inertia, but the seismic effect is limited, and the force of the elastic element is fixed, and the vibration inertia will be Because of the different vibration magnitudes, the elastic force of the elastic component needs to be greater than the maximum value of the inertial vibration force to overcome the sloshing. However, when there is no vibration, the elastic force of the elastic component is superfluous and only contributes to The deformation of the reflective sheet is therefore not a good solution.

In view of the lack of the formula, the creator of this case has finally completed the creation of the lever anti-vibration reflector device after several times of research and improvement. The purpose of this case is to provide a reflector device that utilizes leverage to enhance the seismic effect.
