## Title
Blind region mirror structure and vehicle using the same

## Abstract

A mirror structure permitting an undistorted view of the blind spots of a vehicle include a first lens module and a second lens module. The first lens module is mounted on an A-pillar of a vehicle and located outside of the vehicle; the second lens module is opposite the first lens module and mounted inside of the vehicle on the A-pillar. The first lens module focuses light beams which would otherwise be blocked by the A-pillar of the vehicle and transmits the light beams to a front windshield of the vehicle, the light beam passing through the front windshield to reach the second lens module, the second lens module diffusing the light beams into the vision of a driver.

## Background
FIELD
The subject matter herein generally relates to driving safety.
BACKGROUND
Vehicle bodies generally have an A-shaped pillar between each of the front doors and front windshield, used to protect the driver. In order to strengthen the A-pillar, the width of the A-pillar is wide. Therefore, car driving especially during turning is dangerous; the A-pillar can block the driver's sight and form a blind region. Generally to reduce the blind region concave or convex mirrors can be fitted to the front windshield. However, concave and convex mirrors give a distorted image to the driver.



BRIEF DESCRIPTION OF THE DRAWINGS
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
FIG. 1 is a diagrammatic view of a part of vehicle including a blind region mirror structure, according to an embodiment of the present disclosure.
FIG. 2 is a diagrammatic view of a blind region mirror structure shown in FIG. 1.



DETAILED DESCRIPTION
This disclosure provides a blind region mirror structure for a vehicle in which the driver can see the surrounding scene without distortion.
A vehicle comprises a vehicle body, a front windshield, a left front door, a right front door and at least one blind region mirror structure. The vehicle body includes at least one A-pillar, the blind region mirror structure being set on the A-pillar.
The blind region mirror structure comprises a first lens module and a second lens module, the first lens module is located outside of the vehicle and the second lens module is located inside of the vehicle. The first lens module includes a first convex lens, a first concave lens, a first reflection mirror, and a second reflection mirror. The first convex lens is mounted away from the A-pillar; the first reflection mirror is opposite to the first convex lens and mounted on the A-pillar. The first concave lens is set between the first convex lens and the first reflection mirror, the second reflection mirror aligns with the first reflection mirror and is mounted on the front windshield. The second lens module includes a third reflection mirror, a fourth reflection mirror, a second concave lens, and a second convex lens. The third reflection mirror is aligned with the second reflection mirror and is mounted on the front windshield; the fourth reflection mirror is aligned with the third reflection mirror and is mounted on the A-pillar. The second convex lens is mounted away from the A-pillar and is opposite to the fourth reflection mirror, the second concave lens is set between the fourth reflection mirror and the second convex lens and is aligned with the fourth reflection mirror and the second convex lens. A light beam which would be blocked by the A-pillar of the vehicle is focused by the first convex lens and transmitted to the first concave lens, then transmitted by the first concave to the first reflection mirror, and reflected to the second reflection mirror. The light beam passes through the front windshield of the vehicle to reach the third reflection mirror. The light beam is transmitted to the second convex lens by the second concave lens after being reflected by the third and fourth reflection mirrors. The second convex lens is capable of diffusing the light beam.
Since the external light beam does not change direction in passing through the blind region mirror structure, the driver can see all surrounding scene without distortion, thus promoting safer driving.
