雨天或者冬季行车的时候最怕什么,我想很多朋友一定会说是打滑刹车距离增大,但对于绝大多数城市开车的朋友来讲,我认为最害怕的就是车窗起雾,这样会非常影响司机的开始视线,增加安全隐患。可能这时候会有朋友说,打开车内的除雾功能,雾气就会很快消除了。没错,为了消除车内的雾气我们的车辆都会配备前风挡除雾功能,可是后风挡呢?
如果仔细观察过车辆后风挡的朋友应该都会注意到,后风挡玻璃上会有很多细细的横线,它们整齐的排列在后风挡玻璃上,我想有很多新手司机一定会说,这些横线在一定程度上会影响驾驶员的视线。其实大部分车主不知道,这些”横线”的作用可真的不小。
一、 “横线”是什么能起什么作用
我们后风挡上的”横线”其实是电阻丝,当后挡风玻璃起雾、起霜时,通过发热来使雾气和霜散去,从而保证清晰的后方视线,它需要配合车内的除霜按键使用,通过电阻丝发热使得车窗玻璃上的霜花或水蒸气融解蒸发,这样无论什么时候从车子后玻璃向外看时,都可以看得十分清晰。
二、后风挡除雾功能如何使用
相对于汽车空调的使用比较容易操作和掌握外,其实我们车内的空调是无法照顾到后风挡的,所以厂家会专门给后风挡设计一个除雾的按键,它的图标如上图所示,当后风挡玻璃出现雾气,积雪,结冰的时候,我们只需要按下这个按键,过一会它们就都会被电热丝加热所蒸发或者融化了。
三、后风挡除雾功能使用注意事项
电阻丝在使用时也需要注意,不能太过频繁,也不宜长时间加热,因为电阻丝加热而导致的后挡风玻璃炸裂的事情并不少见,如果后挡风玻璃贴了膜,加热后也容易气泡和脱落,所以说在后挡风玻璃上尽量别贴膜。
在北方寒冷地区,用来除霜、除积雪没问题,南方地区还是应谨慎使用,并且在电阻丝之中,会有几排车载媒体的天线,一般在玻璃上端几排,用来接收无线电信号,因为其在玻璃内呈网状排列,具有寿命长、不易折断、接收信号好的特点。
四、为什么不建议给后风挡玻璃贴膜
换过车膜的朋友相信都知道,后车膜撕下来是多么的繁琐,若是没有熟人的话,很多装饰店其实是拒绝给换的,因为后车窗与其他的玻璃不一样,里面有加热丝的存在,在撕下的过程过中处理不当,非常容易让加热丝断裂,从而失去后车窗除雾功能。如果小心翼翼撕下的话,又非常的耗时间,因此,这种活他们不愿意干。
所以后挡风玻璃就尽量不要贴膜,因为当后挡风玻璃车膜坏了,想重新贴膜,在撕下车膜时很容易对细线条造成损坏,影响后挡风玻璃除霜除雾功能,得不偿失。
五、如果一定要贴请选择大牌正规的汽车美容店
看到这里一定会有朋友会提出这样的质疑,难道后风挡就一定不能贴膜,膜贴上就不能撕了吗?
答案是否定的,毕竟任何事都没有绝对的正确,后风挡当然可以贴膜也可以撕膜,只不过凡是出现电热丝损坏的情况,都是因为技术人员不专业,并且暴力的行为所导致!因为电热丝表层有釉质,撕膜时如果操作不当,即使没有弄断电热丝,也有可能损伤釉质。虽然不影响使用,但它日后会变色影响美观度。
如果真的想撕掉,最好还是到专业的贴膜店,技师会先把膜烤软,喷水泡着,慢慢地在不损伤后风挡玻璃的前提下把旧膜揭掉!而前提是,贴膜的质量也需要保证,否则也会出现电热丝算坏的情况!
侦探总结:一个小小的功能就能解决掉一个大的问题,一个小小的问题可以折射出很多的小知识,我觉得这就是汽车为什么会被称为21世纪最伟大的发明了。其实车上还有很多你不知道或者从来都没用过的小功能,细心地你们赶紧去找找看吧,说不定会有意想不到的惊喜哦!欢迎大家给我们留言并参与讨论,把你的观点分享出来。
