Description

Top-to-back motorized reflector device

technical field

The present invention relates to a kind of back-to-back motorized reflector device, especially a reflector device used in head-up display, which can keep the reflector close to the windshield of the car, so as to increase the stability of the reflector, so that The display image will not shake, thereby improving the viewing quality.

Background technique

The use of the head-up display (Head Up Display) originated in aviation technology at the earliest. Its purpose is to facilitate the pilot to obtain the required information, avoid looking down at the information on the instrument panel, and directly project the information on the front of the cockpit, so that the pilot can Easily combine the external scene with the data displayed on the head-up display. Since the image reflected into the eyes is balanced with the center axis of the aircraft, the pilot's height does not cause deviations in pitch angle or visual aiming. For this reason, the purpose of the design of the head-up display is to prevent the pilot from looking down at the data displayed on the instrument panel, and always keep the head-up posture, so as to reduce the gap between head-down and head-up, and ignore the rapid changes in the external environment, and reduce the need for constant adjustment of the eye focus. resulting delay and discomfort.

When driving, once the driver's eyesight leaves the road ahead, a car accident may occur if he is not careful. In order to reduce the number and time of the driver's eyesight leaving the road ahead, some car manufacturers will equip high-end cars with heads-up displays. The driver's line of sight can also know some information such as speed per hour, engine speed, etc. without leaving the front windshield, so as to maintain driving safety.

Under normal driving conditions, it takes the driver's eyes away from the front to read the information on the instrument panel, and it takes 0.5 seconds at the fastest. The greater the number, the greater the risk. For the sake of safety, some car models are equipped with head-up displays to reduce the distraction of car drivers, and use the head-up displays as a marketing gimmick to attract consumers' purchase intentions.

The head-up display technology used in cars today is less sophisticated than the head-up displays on airplanes. It is an optical system, generally composed of two main devices: a projector and a multiplex mirror. The projector is composed of a signal light source, a projection mirror, and other optical components. The signal light source of the projector is composed of devices such as LCD liquid crystal display or CRT cathode ray tube. The mirror displays text or images.

In recent years, many external head-up displays that can be installed on the car have also appeared on the market. The functions of these heads-up displays range from the simplest display of speed and speed, to now even water temperature, throttle position, fuel level, overspeed warning, reversing image, battery voltage, and even speed radar. Some products also emphasize quick installation, as long as they are connected to the car computer, no additional wiring is required. Some high-end car models of car manufacturers even add information such as navigation system and front and rear distances to the information displayed on the head-up display, which adds a lot of convenience to the driver. The prices of external head-up displays on the market range from a few hundred yuan with simple functions to tens of thousands of yuan with excellent quality and various functions.
