LC车头是引擎盖弹起设计
用pop up hood, pop up bonnet, active bonnet可以找到满多影片的

这类的引擎盖会在侦测到撞击时弹起，达到更好的缓冲效果保护行人
Vulnerable Road User (VRU) Protection

EU-NCAP对应行人防护有分头部、大腿(骨盆)、小腿以及AEB几种测试

NHTSA这篇文章也是在讲Pop up hood对行人的防护
挑几个结论来看
‧ Since 2010, vehicles with pop-up hoods generally produced better Euro NCAP
headform scores on average: 17.2(out of a possible 24) for cars with pop-up
hoods vs. 13.8 for cars with non-deploying hoods.
有引擎盖弹起设计的对行人头部防护能力更好
‧ Pop-up hood technology is generally more costly than other passive
strategies for protection pedestrians, but this examination of pop-up hood
trends showed that sometimes a pop-up hood can lead to lower HIC values
while enabling the vehicle to attain a better Euro NCAP score and still
achieving a desired vehicle style.
成本较高，但在NCAP分数也会更好
一般乘用车引擎盖outer panel、inner panel大概约1mm内
引擎室设计撞击时
1. 引擎盖会向上弯折
2. 主要重量(引擎)下沉
3. 溃缩区吸能
力传递路径：防撞横梁 => 吸能盒 => 前纵梁

→ z85917131 : 轮都没位移有点猛09/30 12:21
若前轮没位移代表主要是靠吸能盒缓冲
至于RAV4，后厢结构有个铝合金后防撞横梁，再来就是C柱下方连接的横梁了

一般设计上C柱以后的行李箱空间不太会用高强度钢
