Description

A screen display rearview mirror system

technical field

The utility model belongs to the technical field of automobile interactive control, and relates to a rear view display system replacing an interior rearview mirror, in particular to a display screen rearview mirror system.

Background technique

The interior rearview mirror is a flat mirror that reflects the real distance behind the car. The interior rearview mirror can help the driver observe the road conditions behind the car and determine the distance to the object behind the car when the vehicle is overtaking, changing lanes, braking suddenly, and some bad weather causes the vision of the exterior mirror to be affected. , to avoid driving accidents.

Car interior rearview mirrors are divided into 3 types: 1. Manual anti-dazzle rearview mirror; 2. Automatic anti-dazzle rearview mirror; 3. Streaming media rearview mirror. Dazzling is generally when driving at night, the lights of the vehicles behind illuminate the surface of the interior rearview mirror and reflect to the human eyes, resulting in night blindness of the driver, and the disappearance of the light source in time will also cause residual images in the driver's eyes, reducing the driver's reflection time. , bringing a greater risk of driving accidents. The principle of manual anti-glare is to suppress the dazzling generation through the optical principle. There is a lens angle adjustment lever on the manual anti-glare inner rearview mirror. The lens is a wedge-shaped prism of about 10°. The thickness of the upper part of the lens is larger than that of the lower end. Under normal conditions, the imaging surface of the rearview mirror is the coating refraction on the back of the lens. After entering the eyes, the imaging principle is the same as that of ordinary flat mirrors. When the angle adjustment lever is pulled to the anti-glare state, the entire lens will be adjusted upward by about 10°. Human eye imaging, the refraction of light is low, to achieve anti-glare effect. The automatic anti-glare interior rearview mirror is equipped with a photodiode behind the mirror surface. When the diode senses strong light, the control circuit will apply a voltage to the ionosphere of the mirror surface. Under the action of the voltage, the lens will be darkened to achieve the purpose of anti-glare. , The automatic anti-dazzle rearview mirror can prevent glare, but when reversing from the garage, because the light behind the car is strong and the light in front of the car is weak, if the rearview mirror becomes dark at this time, it is not conducive to see clearly when reversing Therefore, some cars are designed to automatically cancel the anti-dazzle function when the car is in reverse gear, or the function can be manually canceled with a switch. The streaming media rearview mirror is to use the real scene display technology to combine the camera function with the traditional car rearview mirror to project the real-time real-time image behind the car on the mirror surface. The advantage of this system is that the visual range of the traditional interior rearview mirror is greatly improved, which is more conducive to the safety of driving and parking. The streaming media rearview mirror can also integrate navigation, driving recorder, reversing image, entertainment information display, etc. A variety of functions. It can also avoid the problem of rear passengers or headrests blocking the view of the rearview mirror.

The prior art has the following disadvantages

1. The interior rearview mirror will occupy part of the roof space, which will block the front view to a certain extent;

2. Although anti-dazzling rearview mirrors are very common, the anti-dazzling effect is limited. Even if streaming media rearview mirrors, their mirror shells still have the risk of dazzling, and rearview mirrors cannot completely avoid dazzling;

3. For ordinary interior rearview mirrors, different drivers need to adjust different positions, and the design cannot directly match every driver

4. The more functions of the rearview mirror, the more equipment is required, and the rearview mirror will shake during the driving process of the vehicle, which will affect the function of the rearview mirror;

5. When observing the interior rearview mirror, it is necessary to temporarily leave the front, which affects the driver's attention and poses a safety hazard.

SUMMARY OF THE INVENTION

In order to overcome the above problems existing in the prior art, the utility model provides a rear view display system that replaces the interior rearview mirror; solves the problem that the interior rearview mirror is observed to leave the front view, and at the same time, saves the use of the rearview mirror. Due to space requirements, the shape and front vision are improved, and at the same time, there is no need to consider the dazzling problem of the lights behind the vehicle; the road condition information behind the vehicle is collected by a streaming camera and displayed on the display screen of the windshield directly in front of the driver.

The utility model is realized by adopting the following technical solutions:

A screen display rearview mirror system is characterized in that it includes a streaming media camera, a display screen and a windshield display controller, the streaming media camera is arranged under the rear windshield of the vehicle, and the display screen is embedded in the front windshield of the vehicle. The display element, or the film display screen pasted on the inner surface of the front windshield of the vehicle, the windshield display controller is installed in the vehicle and connected with the power supply controller in the vehicle, the streaming camera and the display screen are connected to the windshield display controller connect.

Further technical solutions are:

For the streaming media camera, a camera with waterproof performance of IPV6 and a field of view angle of 80°±10° in the horizontal direction and 20°±10° in the vertical direction is selected.

Compared with the prior art, the beneficial effects of the present utility model are:

The streaming media camera in the utility model starts working as soon as the vehicle is started, and collects the information behind the vehicle in real time. Vertical: 20°±10°, the field of view is equivalent to 5 times that of ordinary optical rearview mirrors, fully covering the lane behind the vehicle, providing a larger rear field of view; the waterproof performance of the camera is IPV6, which still does not affect the work in heavy rain conditions performance, the camera surface is also not affected by rain.

The windshield display is a windshield that can display image information. The display function can be embedded in the windshield, or a film display is pasted on the inner surface of the glass. The display area of the rearview mirror can be adjusted according to the driver's driving habits. Adjust the position so that it fits the driver's comfortable viewing angle without shifting the line of sight away from the front view to ensure driving safety.

The windshield display controller can realize the real-time display of the image collected by the streaming media camera to the display area of the windshield display, and supply the power of the streaming media camera and the windshield display to ensure the normal operation of the rear view display system.
