后视镜可以加装小圆镜。

后视小圆镜是一种保证驾驶安全,能增大驾驶员观察视角,具有超车和变道的辅助作用。

小圆镜也是一种理想的倒车辅助工具,一般是安装在左右后视镜下方位置。在安装了后视小圆镜的车辆上,驾驶员能看到车身侧面的情况,以及后轮的情况,这也是后视小圆镜最大的用处。需要注意的是,后视小圆镜在变道转向时,是看不到盲区的,特别是晚上。

后视镜是驾驶员坐在驾驶室座位上直接获取汽车后方、侧方和下方等外部信息的工具。为了驾驶员操作方便,防止行车安全事故的发生,保障人身安全,各国均规定了汽车上必须安装后视镜,且所有后视镜都必须能调整方向。

扩展资料

后视镜的调节方式可以分为车外调节和车内调节2种:

1、车外调节式这种方式是在停车状态下,通过用手直接调节镜框或镜面的位置的方式来完成视角的调节,该方式费时费力,很难方便地一次性完成,驾驶员需在座位上用手伸出车窗外调节,在行车、雨天等情况下调节很不方便。一般的大型汽车、载货汽车和低档客车都采用车外调节方式,以降低成本。

2、车内调节式这种方式可为驾驶员在行驶过程中调节后视镜,观察后视野提供较为方便的条件。中、高档轿车大都采用车内调节方式。该方式又分为手动调节式(钢丝索传动调节或手柄调节)和电动调节式2种。

由于后视镜的位置直接关系到驾驶员能否观察到车后的情况,而驾驶员调整它的位置又比较困难,尤其是前排乘客车门一侧的后视镜。因此,现代汽车的后视镜基本都为电动的,由电气控制系统来操纵。 

后视镜的设计:

在设计后视镜的时候,主要的设计要点有:

后视镜可获取的视野(间接视野)、影像的变形、影像的鲜明度、影像的大小、影像在后视镜的位置等,易于进行与驾驶员的视点变化相对应的调整。后视镜应安装在车身上下振动最小的位置上。

后视镜的镜面形状分类:

可分为平面镜、球面镜和双曲率镜面三大系列。另外还有一种棱形镜,棱形镜的镜表面平坦,但其横截面为棱形,通常用作防眩目型的内后视镜。

一、这要根据个人开车习惯,如果装上开车更方便,觉得有用就可以装一个。如果平时都不看,那装上也是摆设,就没必要装。新手建议装一个,可以看保险杠位置的死角,当然技术好就没有这个必要。
二、右侧后视镜调节时尽量外展,可消除车体右后方盲点,小圆镜可以贴在后视镜下方,停车时得以补充观察右后轮位置与旁车距离。

回答3:

有必要,在很多汽车现有的反光镜都有死角也就是视觉盲区,加一个小圆镜可以解决盲区的问题
希望对你有用,望采纳

回答4:

看你自己的需求了
如果没有倒车后视镜自动位置记忆,你又不想每次都调节后视镜,这个东西是可以帮上忙的,靠边停车和倒车的时候可以看看路牙、低矮障碍物什么的,比较方便
一般正常行驶的话,这东西还是偏小了点,还是要养成经常看后视镜的习惯,预见性的判断后车和自己的距离
