 本发明的实施方式
下面结合附图和实施例，对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型，但不用来限制本实用新型的范围。
本实用新型的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
如图1到图2所示，本实施例提供一种车辆，该车辆的左前部设有A柱总成，A柱总成包括自车内到车外依次设置的A柱内板1、A柱加强板2以及部分的侧围外板3，其中A柱内板1与A柱加强板2主要通过焊接固定连接，A柱加强板2与侧围外板3主要通过焊接固定连接；特别地，在A柱内板1和A柱加强板2之间互为相对侧地设有第一补强板4和第二补强板5，如图3和图4所示，A柱内板1与A柱加强板2合围构建出一第一腔体I，A柱加强板2与侧围外板3合围构建出一第二腔体II，第一补强板4和第二补强板5分别和A柱内板1与A柱加强板2通过焊接固定连接，该第一补强板4和该第二补强板5能够增加A柱总成的整体强度，以确保工程师能在A柱总成的强度足以通过相关测试（例如中保研C-IASI侧正面25%偏置测试）的前提下，尽可能地缩减A柱总成的截面尺寸，从而达到减小A柱障碍角的目的。
具体地，侧围外板3上设有用于安装车辆左前门的前车门安装区31，侧围外板3于其位于前车门安装区31上方的框架部分与A柱加强板2相连；在前车门安装区31的上方，A柱加强板2于其前部和中部与侧围外板3固定连接；在A柱加强板2的前部和中部，A柱内板1与A柱加强板2固定连接；在A柱内板1的后部，A柱内板1与车辆的一横梁9固定连接。本实施例中，第一补强板4的截面尺寸和整体体积均小于A柱内板1，第二补强板5的截面尺寸和整体体积均小于A柱加强板2，第一补强板4和第二补强板5分别具有与A柱内板1和A柱加强板2相似的截面形态和相同走向，并能分别与A柱内板1和A柱加强板2紧密贴合，以便分别对A柱内板1和A柱加强板2起补强作用。优选地，第一补强板4和第二补强板5始终相互间隔地位于第一腔体I内，为各自独立互不接触的两个零件，以便能在制备过程中分别成型并与对应的A柱总成的部位相连，同时避免增加A柱总成的制备工艺的复杂性。
更优选地，如图5所示，A柱内板1上设有第一形态区11和第二形态区12，其中A柱内板1在第一形态区11内的横截面宽度大于其在第二形态区12内的横截面宽度，第二形态区12位于第一形态区11的前方并为A柱内板1的形成A柱障碍角的区域，同时第一形态区11和第二形态区12的交界之处大致为A柱内板1的与横梁9相连的位置，横梁9在第一形态区11内与A柱内板1相连，以确保A柱内板1的截面尺寸的变化不会在其上形成过于薄弱的区域；如图6和图7所示，由于相对于第二形态区12，A柱内板1在第一形态区11内（因截面尺寸较大而）具有较高的强度，因此第一补强板4与第一形态区11相贴合的部分的横截面大致为一字型，以节省其成型所需材料，同时第一补强板4与第二形态区12相贴合的部分的横截面呈U型，以进一步确保A柱总成在对应第二形态区12的位置的强度和抗扭转性。
此外，本实施例中的第二补强板5于长度方向上的任何位置均具有U型的横截面，以确保其自身也具有较高的抗扭转性。需要说明的是，前述设计将使得第一补强板4和第二补强板5在第二形态区12内呈开口相对的形态（见图4），如此，第一补强板4与第二补强板5之间的第一腔体I相当于形成了一个供A柱总成受撞击后溃缩的余量空间，能进一步加强A柱总成受到撞击时的抗扭转性能。
更优选地，为了进一步地确保A柱总成在A柱内板1的第一形态区11和第二形态区12的交界之处不会形成过于薄弱的区域，自该交界之处往后，A柱加强板2的截面尺寸大于其与A柱内板1的第二形态区12相对应的部分。
请转回参阅图1和图2，本实施例中，第一补强板4的长度约为第二补强板5的二分之一，侧围外板3的前边沿位于A柱加强板2的前边沿之后，A柱内板1的前边沿位于侧围外板3的前边沿之后，第一补强板4的前边沿位于A柱内板1之内，第二补强板5的前边沿位于侧围外板3的前边沿之后、A柱内板1的前边沿之前以及位于A柱加强板2之内，同时A柱内板1的后边沿位于车门安装前31的后边沿之前，A柱加强板2的后边沿位于前车门安装区31之后，第一补强板4的后边沿位于前车门安装区31的上方并位于A柱内板1之内，第二补强板5的后边沿位于前车门安装区31之后并位于A柱加强板2之内。如此将A柱内板1、A柱加强板2、侧围外板3、第一补强板4和第二补强板5各自的前后边沿错落布置的目的在于，避免车身上出现过于集中的部件分缝区域（也可称拼接区域），从而在A柱总成上形成过分薄弱区域，影响到A柱总成的抗撞击性能和总体强度。
进一步地，如图4所示，本实施例中第一补强板4和第二补强板5通过焊接分别与A柱内板1和A柱加强板2相连的具体方案包括：在第一形态区11焊接第一补强板4和A柱内板1时，令具有U型横截面的第一补强板4的底壁和两侧壁上分别存在焊点6，以确保第一补强板4和A柱内板1之间焊连的稳固性；同理，在焊接具有U型横截面的第二补强板5和A柱加强板2时，令具有U型横截面的第二补强板5的底壁和两侧壁上分别存在焊点6，以确保第二补强板5和A柱加强板2之间焊连的稳固性。优选地，为了确保第一补强板4和A柱内板1之间或第二补强板5和A柱加强板2之间的焊连的稳固性，当第一补强板4具有一字型横截面时，其上的焊点6的直径至少为4-6mm；在具有U型横截面的第一补强板4或第二补强板5的底壁或两侧壁上，焊点6直径为至少4-6mm；与之相对地，此时第一补强板4和第二补强板5的侧壁的高度至少为8mm，以提供足够形成焊点6的平台。
更进一步地，在A柱总成上还设有数个安装孔7，该安装孔7贯穿A柱内板1和第一补强板4，用于为车辆的附件（例如安全气囊总成，图未示）提供安装点；此外，本实施例于第一补强板4对应安装孔7的开设处还焊连有对应的固定件8（例如螺母），以便使固定件8与车辆对应附件安装时需要用到的紧固件（例如螺栓，图未示）形成配合，从而在车辆附件与A柱总成之间构建出具有高可靠性的紧固结构。
此外，在某些可能的实施例中，前述侧围外板3的设计参数包括：厚度为0.65mm，由深冲镀锌钢板DC56D+Z制成。前述A柱加强板2的设计参数包括：厚度为1.8mm，由CR950/1300HS AS75/75制成。前述第一补强板4的设计参数包括：厚度为1.2mm，由CR950/1300HS AS75/75制成。前述第二补强板5的设计参数包括，厚度为1.8mm，由CR950/1300HS AS75/75制成。在某些可能的实施例中，第一补强板4和第二补强板5由热成型加工得到。
综上所述，通过在A柱总成内设置第一补强板4和第二补强板5，本实用新型能够提升A柱总成的强度；由于A柱总成的强度得到提升，工程师在A柱总成的强度足以通过相关测试的前提下，能够尽量减小A柱总成的截面尺寸，从而达到减小A柱障碍角，增强行车安全性的目的。经验证，相较于未设置第一补强板4和第二补强板5的方案，本实用新型结构中的A柱总成的外表面宽度至少能减少5mm。进一步地，由于减小了A柱障碍角，本实用新型还能够提升驾驶员的整体视觉体验。
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以所述权利要求的保护范围为准。
