相关申请的交叉引用
本申请基于申请号为202310591606.6、申请日为2023年05月23日的中国专利申请提出，并要求上述中国专利申请的优先权，上述中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及车辆技术领域，特别涉及一种前机舱下护板和车辆。
背景技术
为了提升整车空气动力学设计减少风阻，目前的车辆采取的是在车身底部加装整个护板的方案，减少风阻的同时也提升整车的NVH性能。但是，该方案将整个前机舱都进行了密封，外界新风从散热器进入后只能在机舱内部循环，降低了散热模块的散热效率。
发明内容
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。
为此，本申请的一个目的在于提出一种前机舱下护板。
本申请的另一目的在于提出一种车辆。
本申请提供一种车辆的前机舱下护板。所述前机舱下护板分为第一护板件和第二护板件，所述第一护板件设置在所述前机舱前端，所述第二护板件设置在所述前机舱后端。所述第一护板件沿车身的X方向设置。所述第一护板件与所述第二护板件之间相隔预设距离。所述第二护板件的靠近所述第一护板件的一端连接在车辆的前机舱中横梁上。所述第二护板件的背离所述第一护板件的一端连接在所述车辆的电池包安装座上。
如此，本申请的前机舱下护板包括第一护板件和第二护板件，第二护板件设置在前机舱后端且与设置在前机舱前端的第一护板件相隔预设距离，以形成与外界对流的空腔，使得流进前机舱内部并经过散热模块后的热风通过空腔导流至大气中，提升散热模块的散热效率。
本申请还提供一种车辆。所述车辆包括上述实施方式中的前机舱下护板。
如此，本申请的车辆包括前机舱下护板，前机舱下护板包括第一护板件和第二护板件，第二护板件设置在前机舱后端且与设置在前机舱前端的第一护板件相隔预设距离，以形成与外界对流的空腔，使得流进前机舱内部并经过散热模块后的热风通过空腔导流至大气中， 提升散散热模块的散热效率。
本申请的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本申请的实践了解到。
附图说明
图1是相关技术中的前机舱下护板的结构示意图；
图2是本申请某些实施方式的前机舱下护板的结构示意图。
具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
请参阅图1，在相关技术中通过将前机舱下护板设计成沿着车身X方向设置的一体成型的护板，来提升整车空气动力学设计，减少风阻的同时也提升整车的NVH性能。但相关技术中的方案却存在着当外界的新风从散热器进入后只能在机舱内部循环。也即是，当外界的新风流进前机舱内部并经过散热模块后变成热风之后，无法及时的导流至大气中，只能一直在前机舱内部进行循环，导致散热模块的散热效率被降低。
有鉴于此，请参阅图2，本申请提供一种车辆的前机舱下护板100。前机舱下护板100分为第一护板件10和第二护板件30。第一护板件10与第二护板件30之间相隔预设距离。
其中，预设距离可以为预先设置好的距离，预设距离例如可以为3cm、3.1cm、3.2cm、3.3cm、3.4cm、3.5cm、3.6cm、3.7cm、3.8cm、3.8cm、3.9cm和4cm，在此不做限制。
也即是，通过设置第一护板件10与第二护板件30之间相隔预设距离，可以在前机舱内形成一个与外部对流的空腔，使得外界冷风经过散热模块200后变成的热风可以通过外部对流的空腔回流至大气中，以提升散热模块200的散热效率。也即是，散热模块200用于对前机舱内部产生的热量进行散热，第一护板件10可以设置在散热模块200的正下方位置，第二护板件30可以设置在散热模块200的后下方位置，第一护板件10和第二护板件30之间形成的空腔的位置正好位于散热模块200的后方，使得外界冷风经过散热模块200后变成的热风可以通过空腔回流至大气中，从而提升散热模块200的散热效率。
第一护板件10和第二护板件30的材质均可以为铝合金材质，在此不做限制。如此，由于铝合金的质量比较轻且具有一定硬度，因此可以减轻第一护板件10和第二护板件 30的质量的同时，还可以提高刚度。
第一护板件10设置在前机舱前端。第一护板件10沿车身的X方向设置。也即是，第一护板件10可以沿车身X方向延伸设置，并且位于正对于散热模块200的位置上。第一护板件10可以通过螺接或焊接的连接方式沿车身的X方向设置在前机舱前端。如此，本申请的第一护板件10可以通过螺接的连接方式设置在前机舱前端，便于第一护板件10的拆卸和更换。本申请的第一护板件10可以通过焊接的连接方式设置在前机舱前端，使得第一护板件10能够更加牢固的设置在前机舱前端。
第二护板件30设置在前机舱后端。第二护板件30的靠近第一护板件10的一端连接在车辆的前机舱中横梁300上。第二护板件30的背离第一护板件10的一端连接在车辆的电池包安装座400上。
