Description

Device for eliminating blind area of structural part

Technical Field

The utility model relates to an automotive filed, concretely relates to eliminate device of A post blind area.

Background

The structural member of the vehicle, for example, the a pillar, is a pillar between a front windshield and a front door, and a driving blind area is formed due to the opacity thereof, as shown in fig. 1, the vehicle is a right-hand vehicle, a driver is on the left side, a left-side a pillar 3 closer to the driver generates a large blind area 4 (a large included angle), and a right-side a pillar 3 ' farther from the driver generates a small blind area 4 ', and the blind areas 4 and 4 ' prevent the driver from viewing the conditions of the external environment of the vehicle, such as roads, other vehicles, pedestrians, obstacles, and the like, thereby affecting the driving safety.

There are two ways to eliminate the blind area that the structure formed at present: one is to change the structural part into a hollow part and check the environment condition outside the vehicle from the hole so as to eliminate the blind area; the other method is that a display screen is arranged on a structural component, and images outside the blind area are transmitted to the display screen through a camera to form a transparent A column.

Because the hollow part still needs to meet the corresponding structural strength, the holes cannot be too large and too dense, and the opaque part on the hollow part can also influence the driver to correctly identify the environment condition outside the vehicle, the environment condition outside the vehicle cannot be clearly checked by adopting the hollow part; in addition, the glass used for hollowing out the holes has higher requirements. The collision strength is not enough, and the automobile is not adopted by various automobile manufacturers.

The camera is then laid to transparent A post in the vehicle outside, through transmitting the camera picture to the inside display screen of A post, has kept the fastness of traditional A post, can let the driver see the road conditions clearly again through it. Due to the A-pillar modeling, the A-pillar is usually slender and irregular in shape, so that installation and display on a structural member are difficult to match the shape of the structural member, a malformed screen needs to be customized, and the cost is high.

Detailed Description

As shown in fig. 2 and 3, the utility model provides an eliminate device of structure blind area, including image acquisition device and new line display device HUD, image acquisition device is connected with new line display device.

In this embodiment, the structural members are left a-pillars 3 and/or right a-pillars 3'.

The image-presenting layer is formed by coating, overlaying, or surface processing.

The covered image display layer is made of glass, mirror or acrylic. In this embodiment, the inner side surface of the a pillar is covered with the image presenting layer made of glass, in other embodiments, the image presenting layer may also be made of a mirror surface or acrylic, and the image presenting layer may also be formed by coating, surface processing, such as electroplating, pseudo-electroplating.

The image acquisition device is a camera 1, can be arranged outside the vehicle, and is used for acquiring a first image, wherein the first image is an image of an environment outside the vehicle, which is viewed by a driver and blocked by a structural member.

The head-up display device 2 is disposed obliquely below the left a-pillar 3, and the head-up display device 2 'is disposed obliquely below the left a-pillar 3', as shown in fig. 2. In other embodiments, the A-pillar may be disposed obliquely above the A-pillar.

The head-up display device includes a controller 20, a picture generation unit 21, and an optical system (aspherical mirrors 22, 23). Since the inner side surface of the a-pillar is irregular in shape, if an image of an external environment acquired by the camera is directly projected, deformation may occur. The controller is used for carrying out pre-distortion processing on the first image to obtain data of a second image; the picture generation unit 21 is used for generating a display image according to the data of the second image; the optical system is configured to project a display image onto an image presenting layer on an inner side surface of the a-pillar, and display an image of an environment outside the vehicle on the image presenting layer, as shown in fig. 3, and the image of the environment outside the vehicle viewed through a windshield and a window by a driver is spliced together to form a complete image of the environment outside the vehicle.

Therefore, the blind area formed by the A column can be eliminated, so that a driver can conveniently check the conditions of the external environment of the vehicle, such as roads, other vehicles, pedestrians, barriers and the like, and the driving safety is ensured.

On one hand, the head-up display device HUD is arranged obliquely below the A column, and due to the fact that the relative positions of the head-up display device and the structural component are different, the generated distortion (deformation) is different, and therefore pre-distortion treatment needs to be carried out according to the relative positions of the head-up display device and the structural component.

On the other hand, since the image-representing layer attached to the inner surface of the a pillar has a different shape, for example, a curved surface, and the distortion (deformation) is different, it is necessary to perform the pre-distortion process according to the shape of the image-representing layer.

Passenger vehicles generally include a pillar a between a front windshield and a front door, a pillar B between a front door and a rear door, and a pillar C between the rear door and a rear windshield. While larger cars will have a D-pillar.

The left and right B, C or D pillars may form blind spots that prevent the driver or rider from viewing the conditions of the environment outside the vehicle.

Adopt the utility model provides a scheme not only can eliminate the blind area that the A post formed, also can eliminate about B post, C post or D post formation blind area, cover the image in the inboard of these structures and present the layer to use the new line display device who sets up corresponding position, for example oblique below or oblique top, eliminate the blind area that these structures formed.

The structural member may be disposed on a front side, a side, or a rear side of the vehicle.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. Various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is to be determined by the appended claims.
