Description

Anti-dazzling streaming media rearview mirror system

Technical Field

The utility model relates to the field of automobile accessories, in particular to a streaming media rearview mirror system for mastering road conditions behind a vehicle during driving.

Background

The main function of the inside rearview mirror is to observe the road condition behind the driver, and especially at night, when the high beam/low beam of the rear vehicle is illuminated or the surrounding environment is weak, it is very important to the driving safety whether the driver can observe and grasp the road condition behind the rear vehicle in time. The interior rearview mirrors on the market at present have the following types:

1. physics rear-view mirror possesses the anti-dazzling function of manual regulation, and the main shortcoming that exists is: 1) manual adjustment is required. 2) Looking backwards from the rear view mirror, obstacles such as soiling of the rear seat, passengers or rear windshield, etc. may obstruct the view. 3) The rear windshield has small area and narrow visual field, and the blind areas outside the vehicle are more. 4) When adjusting anti-dazzling visual angle, can play certain anti-dazzling effect, nevertheless if under the environment condition of darker, the reflectivity diminishes again simultaneously, has weakened light, probably sees the condition at rear unclear, is unfavorable for driving safety.

2. The electron prevents dazzling rear-view mirror possesses automatic sensitization and prevents dazzling function, and the main shortcoming that exists is: 1) the back row, passengers or back shelves are dirty, and the sight is blocked by the barriers. 2) The rear windshield has small area, narrow visual field and more blind areas outside the automobile. 3) Make the mirror surface darken and play certain anti-dazzling effect through the sensitization, but simultaneously under the environment condition of comparatively dark, because the mirror surface is dark, probably sees the condition at rear clearly, equals interior rear-view mirror and has lost the effect, is unfavorable for driving safety.

3. In the prior art, a rear camera captures an image behind a vehicle and the image is displayed on a screen of the streaming media rearview mirror. The performance effect in the daytime is still good, but the shortcomings of the daytime when the ambient light is insufficient are as follows: 1) when the high beam lamp at the back of the vehicle irradiates, the anti-glare effect on the screen of the rearview mirror is general and even can be whitely lost. 2) When the surrounding environment is dark, the screen of the interior rear-view mirror is basically black. 3) When the environment is too bright, such as under a large sun, the display screen may not be seen clearly due to too low brightness; when the environment is too dark, such as at night, the display screen may be dazzling due to too bright brightness, which affects driving safety.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the present invention aims to provide an intelligent, dynamic and anti-dazzling streaming media rearview mirror system with good visual display effect of streaming media images.

In order to overcome the technical defect, the utility model adopts the technical scheme that: an anti-dazzling streaming media rearview mirror system is composed of an interior rearview mirror and an exterior rear camera.

Preferably, the inside rear-view mirror is provided with a circuit board and a streaming media display screen, wherein the circuit board is integrated with a photosensitive IC, an MCU controller, a CPU image processor and a backlight IC; the photosensitive IC is connected with the MCU controller, the MCU controller is connected with the CPU image processor, the CPU image processor outputs qualified road condition images to the display screen and also outputs qualified backlight parameters to the backlight IC, and the backlight IC controls the height of the display screen.

Preferably, the rear camera is provided with a miniature camera, and the miniature camera is connected with the interior rearview mirror through a wire.

By implementing the technical scheme of the utility model, a set of streaming media rearview mirror system is formed by matching the streaming media rearview mirror with the rear camera, so that an intelligent, efficient and dynamic streaming media anti-glare image is realized after the wide dynamic highlight inhibition anti-glare function of the rear camera, the night dim light and light filling white balance effect of the interior rearview mirror and the screen photosensitive brightness adjusting function of the interior rearview mirror are integrated, the visual comfort is provided for a driver, and the driving safety of the driver is greatly improved.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The anti-dazzling streaming media rearview mirror system is composed of an interior rearview mirror 1 and an exterior rear camera 2, the interior rearview mirror and the exterior rear camera 2 are connected into a system through electric wires, and the exterior rear camera is mounted on the upper edge of a rear windshield of a vehicle.

As shown in fig. 1 and 2, the interior mirror 1 is mainly composed of a front case 1.5, a rear case 1.2, a holder 1.1, a circuit board 1.3, a display screen 1.4, and a glass cover plate 1.6. The rear shell 1.2 is hinged with the support 1.1, the front shell 1.5 and the inner assembly circuit board 1.3 and the display screen 1.4 of the rear shell 1.2, the front shell 1.5 is embedded with a glass cover plate 1.6, and the glass cover plate protects the display screen from being scratched. The corner of the glass cover plate 1.6 is provided with a photosensitive IC1.7, the corner of the rear shell 1.2 is also provided with a photosensitive IC1.7, and the photosensitive IC senses the light intensity inside and outside the vehicle.

As shown in fig. 3 and 4, the vehicle exterior rear camera 2 is mainly composed of a bottom case 2.1, a face cover 2.2 and a micro camera 2.3, the micro camera 2.3 is arranged inside the bottom case 2.1, and the micro camera 2.3 is connected with a CPU image processor through a wire. Shrinkage pool 2.2a has been seted up to face lid 2.2, and the shrinkage pool provides the shooting passageway for miniature camera ware, and the side design of shrinkage pool is the cockscomb structure, and the cockscomb structure shrinkage pool is favorable to refraction light, avoids road conditions light to produce the reflection of light when the shrinkage pool side, influences the real-time effect of making a video recording.

As shown in fig. 5, the circuit board is integrated with a photosensitive IC, an MCU controller, a CPU image processor, and a backlight IC. The photosensitive IC is connected with the MCU controller, the MCU controller is connected with the CPU image processor in an access mode, the road condition record obtained by shooting through the miniature camera is input into the CPU image processor, the CPU image processor outputs qualified road condition images to the display screen, the CPU image processor outputs qualified backlight parameters to the backlight IC, and the backlight IC controls the brightness of the display screen.

The CPU image processor adopts a software algorithm to carry out image digital processing, thereby achieving the effects of strong light resistance and weak light supplementary lighting to achieve white balance, and realizing the problem of dazzling road conditions behind the observation vehicle by matching the rear camera with the streaming media rearview mirror.
