车很多人都开过,聊起来大家都或多或少能说一点关于汽车的知识,也有一些冷门的小技巧和趣味知识是不被人们所熟知的,今天就来跟大家分享一下吧。
打雷时在车内安全吗
答案是待在车里是安全的,当车身在遭到雷击时,电流通过车身和轮胎接通了大地,由于“法拉第笼”原理,可让车内的人员安然无恙。
什么是“法拉第笼”原理,就是当有高压电产生时,根据接地导体静电平衡的条件,笼体是一个等位体,内部电势差为零,电场为零,所以笼体的内部不会有电流通过,人躲在里面也不会触电。(原理可能比较难懂,只要记住不会触电就行了)
虽然雷电击中汽车时人在里面是安全的,但是也要关好窗,尽量不要触碰车上的金属部位,以防意外的发生。
被困车里有几种方法脱困
如果因各种意外被困车里该怎么办?一是砸车窗玻璃,二是有天窗的可以尝试从天窗逃脱,除此之外还可以从后备箱出来。
当然前提是你的车后排座椅能放倒,有些车后排座椅不能放倒就不适合采用这种方法脱困,后背箱盖上一般会有一个拉环,如果不清楚在哪最好查看说明书,找到所在位置拉动就可以解锁打开后备箱。
电动车竟然比燃油车诞生还要早
我们都知道,近些年电动车慢慢的火热起来,给人的印象就是一个刚诞生不久的产业。其实电动车发明的比内燃机汽车早得多,1834年美国人Thomas Davenport就发明了第一台直流电机驱动的电动车,第一台量产的电动车是Thomas Parker 1884年在伦敦制造的。
而1886年卡尔本茨才造出第一台三轮的内燃机车,第一台四轮的内燃机车是1893年才被制造出来。不过由于技术落后,效率不高等原因,电动车一直都没有什么存在感,直到近些年技术比较成熟才又“重出江湖”
引擎盖为什么那么软
有些人看车时比较喜欢按一按车身,比如引擎盖,那些稍微用点力就能微微按凹陷的,就让很多人以为不安全的,也是以前很多人吐槽日系的原因,为什么发动机舱盖要搞得那么轻那么薄呢?
首先是为了保护车内人员,假设你的发动机盖足够硬,在撞上物体的时候,发动机盖有可能直接插入驾驶室,造成二次伤害。其次是为了保护行人,一般在撞上行人的时候,行人脚会腾空,而上半身就会直接撞在发动机盖上,软化的车盖可以减轻对行人的伤害。
引擎盖做硬并不难,但是这样做并没有必要。汽车是否安全主要是看车内的钢梁强度和结构,车身那层铁皮对行车安全的影响微乎其微。
大众卖香肠比车卖的还多
大众汽车我们都知道,大众还卖香肠你知道吗,大众香肠的诞生始于1938年,由于德国政府决定在沃尔夫斯堡建立群众厂区,大众总部人数在短时间内剧增,为了解决自己员工吃饭的问题,大众就成立了肉制品加工厂,甚至还建立农场,实现自己动手丰衣足食。
所以这不是贴牌,而真的是大众集团旗下的产品。大众香肠每一年的销量在600万-800万之间,而汽车的产量在500-600万之间,可以说大众香肠每一年的销量都比大众汽车的销量高了。
遮阳板还能往侧面掰
汽车遮阳板,也是车里比较实用的一个配置,遮阳板可以有效阻挡来自前方的耀眼的光线,有助于我们保持清晰的视线,安全行驶。
其实遮阳板不仅仅能够遮挡来自前方的光线,还可以遮挡来自侧面的日晒。如果仔细观察你会发现有一侧的卡口是开放的,只需轻轻用力把这边掰出来,然后就可以转到侧面去了。
