The mirror surface is formed by evenly combining a plurality of the cambers having different radius of curvature into a composite surface. The surface of the mirror is characterized by which the curvature radius in the middle and upper of the mid-column section of said mirror surface are large and decreasing from up to down; the distribution of curvature radius are firstly decreasing and then increasing from said middle and upper of mid-column to outside; the outline of the mirror is designed to a shape having narrow-upper and wide-lower with streamline; and there is provided a reference point for the driver on said mirror surface. The mirror of present invention can provide clear image and wide view, and having advantage of eliminating blind spots in two sides and ahead of the vehicle.

Description

车辆外置全枧镜. 发明领域本发明涉及一种反光镜装置，特别涉及车辆光学观察装置。技术背景 External full mirror for vehicle. FIELD OF THE INVENTION The present invention relates to a mirror device, and more particularly to a vehicle optical observation device. technical background

现有的车辆外置后视镜大致分为以下两种类型，一种是圆凸镜, 一种是平面镜。前者视野宽，但影像失真严重，看不远；后者看得远且影像清晰不失真，伹视野窄，看不到车前及车辆侧前轮附近的盲区。这一缺点给驾驶员带来了变道或转弯时的困难及危险，甚至因此而发生交通事故，对于大、中型客车来说这一缺点带来的危害尤为严重。据统计，大约 2 0 %至3 0 %的交通事故发生在这三个盲区。人们为了解玦以上问题，想过许多办法，一种是如中国专利 C N 9 0 2 0 6 8 9 4 . 6 和中国专利 C N 9 4 2 0 7 4 8 9 . 0 所公开的车辆外置后视镜，其镜面是由多个不同曲率半径的面圆清连接而成的复合曲面，从上至下曲率半径越来越小，上半部镜面曲率半径很大，下半部镜面的曲率半径不但从至下越来越小，而且从一侧至另一侧也是越来越小。这种后视镜^ Γ有影像清晰度高，视野宽的优点，由于它的不对称，分左、右镜，成对使用时，可消除车体两侧的盲区，但车前的盲区仍末消除。另一种是同时装有圆凸镜和后视镜，驾驶员需观察不同的镜子监视车前到车辆侧盲区。然而在一面镜子中还不能消除车前及车恻的盲区。 Existing exterior mirrors for vehicles are roughly divided into the following two types, one is a round convex mirror and the other is a flat mirror. The former has a wide field of view, but the image is severely distorted and cannot be seen far away; the latter can see far and the image is clear and undistorted. The narrow field of view can not see the blind area in front of the car and near the front wheels on the side of the vehicle. This disadvantage brings difficulties and dangers to the driver when changing lanes or turns, and even causes traffic accidents. This disadvantage is particularly serious for large and medium-sized passenger cars. According to statistics, about 20% to 30% of traffic accidents occur in these three blind spots. In order to understand the above problems, people have thought of many ways, such as the Chinese patent CN 9 0 2 0 6 8 9 4. 6 and the Chinese patent CN 9 4 2 0 7 4 8 9. 0 Sight glass, the mirror surface of which is a composite curved surface formed by the connection of a plurality of surfaces with different curvature radii, the radius of curvature from the top to the bottom is getting smaller and smaller, the curvature radius of the upper half is large, and the curvature radius of the lower half is Not only is it getting smaller from bottom to bottom, but it is getting smaller from side to side. This rear-view mirror ^ Γ has the advantages of high image clarity and wide field of view. Due to its asymmetry, it can be divided into left and right mirrors. When used in pairs, the blind areas on both sides of the car can be eliminated, but the blind areas in front of the car are still End elimination. The other is equipped with a round convex mirror and a rearview mirror at the same time. The driver needs to observe different mirrors to monitor the front of the car to the blind area on the side of the car. However, blind spots in front of the car and in the car can't be eliminated in a mirror.

本发明的目的是提供一种车辆外置全视镜。该镜为一片镜面，在获得视野宽、影像清晰的同时，又能清除车前及车侧的盲区。 An object of the present invention is to provide a vehicle exterior full-view mirror. The mirror is a mirror, which can obtain a wide field of vision and clear images, while clearing the blind areas in front of and on the side of the car.

本发明的另一个目的是在上述车辆外置全视镜的基础上，提供一种能显示出后面来车与本车位置关系的车辆外置全视镜。发明简述 Another object of the present invention is to provide a vehicle external full-view mirror capable of displaying the positional relationship between a coming vehicle and a host vehicle based on the vehicle external full-view mirror.

The mirror surface of the external full-view mirror of the vehicle is a compound curved surface formed by smoothly connecting a plurality of curved surfaces with different curvature radii. The key point is that the upper and middle curvature radii of the middle portion of the mirror surface are large, and from top to bottom The radius of curvature changes gradually from large to small; the middle part moves towards two The curvature radii of the side and the downward portion change from large to small, and from small to large. At the same time, when viewed from the side of the mirror, the curvature radii also change from large to small, and from small to large.

镜面的外轮廓线釆用图示上窄下宽的流线型设计，其构成是由多个不同半径的曲线圆清连接而成的复合曲线, 曲线半径的变化规律是从上至下由大变小，即上边的外轮廓线是半径大的曲线的一段，下边的外轮廓线是半径小的曲线的一段。 The outer contour line of the mirror surface is designed with a streamlined design with narrow upper and lower widths. The composition is a compound curve formed by connecting multiple curved circles with different radii. The curve radius changes from top to bottom from large to small. That is, the outer contour line on the upper side is a section of a curve with a large radius, and the outer contour line on the lower side is a section of a curve with a small radius.

上述第一实施例给出的镜面为不对称设计，此时镜子分左镜和右镜，图 1 所示为右镜，从镜正面看去，镜内侧面 1 的宽度大于铙外侧面 2 的宽度，以便消除车前盲区。 The mirror surface provided by the first embodiment is an asymmetric design. At this time, the mirror is divided into a left mirror and a right mirror. Figure 1 shows the right mirror. Viewed from the front of the mirror, the width of the inner side 1 of the mirror is greater than 铙. The width of the outer side 2 in order to eliminate blind spots in front of the car.

参照图 4 ，第二实施例給出的镜面从中间到两侧的曲面为近似对称设计或完全对称设计，此时镜面的外轮廓线也为近似对称或完全对称。镜子无左右镜之分以便于制作和安装。 Referring to FIG. 4, the curved surface of the mirror surface from the middle to the two sides according to the second embodiment is an approximately symmetrical design or a completely symmetrical design. At this time, the outer contour of the mirror surface is also approximately symmetrical or completely symmetrical. Mirrors are not divided into left and right mirrors for easy fabrication and installation.

参照图 5 ，其为第三实施例的主视图，其不同之处是在镜面上设置若干标志 8 、 9 、 1 0 、 1 1 、 1 2 、 1 3 分别表示上、下、左、右、前、后位置关系参照点，回驶员看到镜中出现车或某物体时，由此可判断出后者距本车的方位。工业实用性 Referring to FIG. 5, which is a front view of the third embodiment, the difference is that a number of signs 8, 9, 10, 1 1, 1 2, 1 3 are set on the mirror surface to indicate up, down, left, right, The reference point of the front and rear position relationship. When the returning driver sees a car or an object in the mirror, he can determine the position of the latter from the vehicle. Industrial applicability

根据车辆后视镜上远下近的光学反射原理，当后车距本车较远时，其影像出现在这种全视镜中间部分的上部镜面中，影像清晰；随着车与本车距离的缩短，它在镜中的影像往下移。左、右各装一面全视镜，由于下部和内外侧面的前述特征，驾驶员不仅能从镜中监视车体两侧前后左右较宽范围，同时能将过去认为的车前盲区尽收眼底。 According to the optical reflection principle of the rear mirror of the vehicle, when the rear vehicle is far away from the vehicle, its image appears in the upper mirror surface of the middle part of this all-view mirror, and the image is clear; as the distance between the vehicle and the vehicle is clear Shortened, its image in the mirror moves down. The left and right sides are equipped with a full-view mirror. Due to the aforementioned features of the lower and inner and outer sides, the driver can not only monitor the wide range of the front, back, left, and right sides of the car from the mirror, and at the same time have a panoramic view of the front blind area.

本发明提供的车辆外置全视镜与已有的大视野后视镜相比较具有如下优点：影像保持清晰的同时，视野更宽阔；不仅消除车体两侧的盲区，同时消除车前的盲区。 Compared with the existing wide-view rear-view mirror, the vehicle external full-view mirror provided by the invention has the following advantages: while the image remains clear, the field of vision is wider; not only eliminates the blind areas on both sides of the vehicle body, but also eliminates the blind areas in front of the vehicle .

因此，本发明的提出的车辆外置全视镜，可用作备种车辆的反光观察镜。 Therefore, the vehicle exterior full-view mirror provided by the present invention can be used as a reflective observation mirror of a prepared vehicle.
