Description

一种轻量化高强度的车身结构
技术领域
本发明涉及汽车制造技术领域，具体来说，涉及一种轻量化高强度的车身结构。
背景技术
在节能、环保和安全成为当今世界汽车工业关注的重要课题的大背景下，汽车轻量化技术的现实意义是毋庸置疑的。汽车轻量化必须是在保证汽车强度和安全性能的前提下，尽可能地降低汽车的整备质量，有效减少燃油消耗，具有很高的技术含量，而不是简单地降低汽车重量。因为降低了汽车重量，虽然有利于改善汽车制动效果，便于主动安全控制，但是碰撞时整个需要被吸收转移的能量就会减少，影响被动安全性，因此，必须综合考虑各种要素来实现汽车轻量化。现有的汽车顶盖虽然实现了轻量化，但由于设计不合理、结构过于简单，导致其强度大大降低，这严重威胁着使用人员的人身安全，因此在考虑轻量化的同时也有必要关注汽车车身强度的设计。
针对相关技术中的问题，目前尚未提出有效的解决方案。
发明内容
针对相关技术中的问题，本发明提出一种轻量化高强度的车身结构，以克服现有相关技术所存在的上述技术问题。
本发明的技术方案是这样实现的：
一种轻量化高强度的车身结构，包括车身本体，所述车身本体顶部前后对称设置有前横梁和后横梁，所述前横梁与所述后横梁之间对称设置有第一纵梁和第二纵梁，且所述第一纵梁的外侧面和所述第二纵梁的外侧面均与所述车身本体固定连接，所述第一纵梁和所述第二纵梁之间设置有顶盖，且所述顶盖的前后两端分别与所述前横梁和所述后横梁固定连接。
其中，所述顶盖包括对称设置的第一连接板和第二连接板，所述第一连接板和所述第二连接板顶端通过外蒙皮连接，所述外蒙皮底面设置有加强筋层，且所述加强筋层两端分别与所述第一连接板内侧面和所述第二连接板内侧面固定连接，所述加强筋层底面设置有缓冲气囊，且所述缓冲气囊两侧面分别与所述第一连接板内侧面和所述第二连接板内侧面固定连接，所述缓冲气囊下方设置有里皮，且所述里皮两端分别与所述第一连接板内侧面和所述第二连接板内侧面固定连接，所述里皮和所述缓冲气囊之间均匀设置有若干组片状弹性件，若干组所述片状弹性件两端均固定连接在所述里皮顶面上，且每个所述片状弹性件顶部均与所述缓冲气囊底面相抵，两所述片状弹性件之间均匹配设置有环形弹性件，若干组所述环形弹性件底部均固定连接在所述里皮顶面上，所述里皮底面设置有内蒙皮，且所述内蒙皮两端分别与所述第一连接板底端和所述第二连接板底端固定连接。
进一步，所述车身本体外表面和所述顶盖顶面均设置有防水层。
进一步，所述加强筋层为玻璃纤维加强筋网。
进一步，所述缓冲气囊采用碳纤维增强复合材料制成。
进一步，所述里皮与所述内蒙皮之间设置有防辐射层。
进一步，所述内蒙皮采用织物材质制成。
本发明的有益效果为：通过将顶盖固定连接在车身本体上，可以有效增大受力面积，从而提高了该车身结构的承载力度，进而有效保护了使用人员的人身安全；通过在顶盖内设置缓冲气囊，可以在提高该顶盖承受力的同时，实现了轻量化，从而提高了该车身结构的实用价值；通过在顶盖内设置片状弹性件和环形弹性件，可以进一步提高该顶盖承受力，从而提高了该车身结构的强度及刚度。
