Description

车辆多曲面无盲区外置后视镜 技术领域
本发明涉及一种车辆光学观察装置， 特别是一种车辆多曲面无 盲区外置后视镜。 背景技术
现有的车辆多曲面无盲区外置后视镜大致分为以下两种类型， 一种是球形镜， 也称单曲面镜， 另一种是平面镜。 前者视野面宽， 但影像失真严重， 距离感差， 使人眩晕， 后者看得远且影清晰不失 真， 但视野窄， 看不到车前及车两侧前轮附近的盲区。 这一缺点给 驾驶员来了变道或转弯时的困难及危险， 甚至因此发生交通事故， 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 20%至 30%的交通事故发生在这三个盲区。 人们为了解决以上问 题， 想过许多办法， 一种是如中国专利 CN90206894.6 和中国专利 CN94207489.0 所公开的车辆外置后视镜， 其镜面是由多个不同曲率 半径的面圆滑连接而成复合曲面， 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上至下越来 越小， 而且从一侧至另一侧也是越来越小。 这种后视镜具有影像清 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， 可消除车体两侧盲区， 但车前的盲区仍未消除。 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两侧 盲区。 然而在一面镜子中还不能消除车前及车侧的盲区, 发明目的
本发明的目的是提供一种视野宽、 影像清晰、 可以清除车侧及 平头车前的盲区， 还能够显示出后面来车与本车位置关系的车辆多 曲面无盲区外置后视镜。 发明简述
本发明的车辆多曲面无盲区外置后视镜的镜面包括多个圆滑连 接的不同曲率半径的曲面， 所述镜面中间部分为一横向抛物线型中 心轴， 中心轴右端为中心点， 所述中心点为最小曲率半径点， 通过 此中心点的横向中心线的最左端为最大曲率半径点； 所述中心点左 端的镜面曲面规律为以中心轴上中心线往上和往下的曲率半径由大 到小又由小到大变化； 所述中心点右端的镜面曲线规律为以中心轴 上中心线往上和往下的曲率半径由小到大变化； 所述镜面从左到右 的曲面规律为由大到小又由小到大变化。
其中， 所述中心点的位置为镜面从左至右的 1/2-2/3处。
所述镜面的外轮廓线可采用左窄右宽的流线型设计， 所述流线 型设计是由多个不同半径的的曲线圆滑连接而成的复合曲线， 而且 从左至右曲率半径由大到小逐渐变化。
所述镜面的外轮廓线还可采用方形、 上平下弧或下平上弧的流 线型设计。 本发明的车辆多曲面无盲区外置后视镜的镜面上还可设有若干 标志点， 如危险区标志点、 警示区标志点和安全区标志点， 使驾驶 员能够从镜中判断后面来车与本车的位置关系。
当所述中心线为水平横向时， 本车辆多曲面无盲区外置后视镜 可用于小型车辆， 当所述镜面旋转 90° 时， 本车辆多曲面无盲区外 置后视镜可用于大型车辆。
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， 其影像出现在这种后视镜中间部分的右部镜面中， 影像清晰； 随着后车与本车距离的缩短， 它在镜中的影像往左移。 左、 右各装 一面全视镜， 由于镜面的前述特征， 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。
本发明的车辆多曲面无盲区外置后视镜与己有的大视野后视镜 相比较具有以下优点： 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； 通过曲面的变化， 使距 离感更强， 便于司机观察判断； 镜中影像不变形， 看后不眩晕。
文中所说的车前盲区主要是指大型平头车辆的车前盲区。 附图简要说明
下面结合附图和实施例进一步描述本发明。
图 1 是一种用于小型车辆的多曲面无盲区外置后视镜的主视 图；
图 2是图 1的俯视图； 图 3是图 1中沿 I一 I线的剖面图；
图 4 是一种用于大型车辆的多曲面无盲区外置后视镜的主视 图；
图 5 是一种带标志点的车辆多曲面无盲区外置后视镜的主视
发明详述
如图 1 所示的镜面是由多个不同曲率半径的曲面圆滑连接而成 的， 镜面中间部分为一横向抛物线型中心轴 16， 中心轴右端为中心 点 1， 所述中心点为最小曲率半径点， 通过此中心点的横向中心线 Π 的最左端为最大曲率半径点 2; 所述中心点左端的镜面曲面规律为 以中心轴上中心线往上和往下的曲率半径由大到小又由小到大 3— 4 一 5、 3 -6-7 变化； 所述中心点右端的镜面曲线规律为以中心轴上 中心线往上和往下的曲率半径由小到大 8— 9、 8- 10 变化； 所述镜 面从左到右的曲面规律为由大到小又由小到大 2— 1一 8变化。
此种镜面的外轮廓采用图示左窄右宽的流线型设计， 其构成是 由多个不同半径的曲线圆滑连接而成的复合曲线， 曲线半径的变化 规律是从左至右由大变小， 即左边的外轮廓线是半径大的曲线的一 段， 右边的外轮廓是半径小的曲线的一段。
实施例一给出镜面为不对称设计， 此时镜子分左镜和右镜， 图 1 所示为右镜， 从镜正面看去， 镜右侧面 1 的宽度大于镜左侧面 2 的宽度， 以便消除车前盲区。 如图 4 所示， 其给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， 便于制作和安装， 适用于大型车辆使用。
如图 5所示， 镜面上设置有若干个标志点， 分别表示危险区 11、 12, 警示区 13、 14和安全区 15位置关系参照点， 驾驶员看到镜中 出现车或某物体时， 可判断后者距本车的方位。
需要说明的是， 文中所述中心线左侧为第一侧， 中心线右侧为 第二侧。 对于小型车辆而言， 第一侧为近车体侧， 第二侧为远车体 侧。 对于大型车辆而言， 中心线旋转了 90°， 因此， 第一侧指镜子的 下侧， 第二侧为镜子的上侧。
