Top-mounted electric reflector device

The present invention relates to a top-mounted electric reflection sheet device, in particular to a reflection sheet device used for a head-up display, which can keep the reflection sheet close to the windshield of the automobile, thereby increasing the stability of the reflection sheet, so that Display images do not sway, which improves viewing quality.

Head Up Display, which is called head-up display in Chinese, originated from aviation technology. It is easy for pilots to get the information they need, avoiding looking down at the information on the dashboard and directly projecting the information on the front of the cockpit. Combine the outside world with the information displayed on the heads-up display. Since the image reflected into the eye is balanced with the center axis of the aircraft, the height of the pilot does not bias the pitch or visual aiming. The head-up display is designed to allow the pilot to look down at the instrument panel without looking down, always maintaining a head-up attitude, reducing the rapid changes in the environment between the head and the head, and the delay and discomfort caused by the constant adjustment of the eye focal length.

When driving, the driver's line of sight leaves the road ahead, which is one of the biggest causes of car accidents. In order to reduce the number and time of the driver's line of sight leaving the road ahead, some depots will be equipped with a head-up display on the premium car so that the driver's line of sight can know some speeds such as speed and engine speed without leaving the front windshield. Wait for information to maintain driving safety.

Under normal driving conditions, the driver's eyes leave the front to read the information on the dashboard. The fastest time is 0.5 seconds. The speed of the highway is 100 kilometers per hour, and the distance is about 30 meters per second. In many cases, the danger increases. For safety, the car factory is equipped with a head-up display on some models to reduce the distraction of the driver and to attract consumers with a head-up display.

The head-up display technology used in today's cars is not as complicated as the head-up display on the aircraft. It is an optical system, generally consisting of two main devices: a projector and a mirror; the projector is composed of a signal source, a projection mirror and other optical components; a signal source of the projector, an LCD liquid crystal display or a CRT cathode ray A device such as a tube emits light from a signal source and then projects through a projector onto a stack of mirrors on a glass (or a special transparent screen), and the overlay mirror displays text or images.

In recent years, there have been many external head-up displays that can be added to the car. These head-up display functions are integrated from the simplest display speed, speed, and now even water temperature, throttle position, fuel volume, overspeed warning, reversing image, battery voltage, and even speed radar. Some products also emphasize quick installation, as long as the computer is connected to the car, no additional wiring is required. Some car manufacturers' advanced models add navigation system and front and rear distance to the information displayed on the head-up display, which adds a lot of convenience to the driver. The price of commercially available external head-up displays ranges from a few hundred yuan with simple functions to over 10,000 yuan with excellent quality and versatility.
