Description

前围板的加强板、前围板组件和车辆
本申请要求于2023年2月9日提交的申请号为202310134140.7、发明名称为“前围板的加强板、前围板组件和车辆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及车辆技术领域，具体涉及一种前围板的加强板、前围板组件和车辆。
背景技术
在相关技术中，由于纯电汽车没有燃油汽车的排气系统，故纯电汽车取消了凸起的中央通道结构，整个地板设计为平面结构。在部分纯电汽车中，地板下部布置有动力蓄电池，汽车前围板为了配合动力蓄电池的布置需求，会在前围板底部外侧增设了两块挡板，从而在前围板和挡板在此区域围成了一个横向的三角形空腔。
但是，由于用于制造前围板与挡板的钣金自身料厚较小，前围板和挡板所围成的空腔面积较大，因此在整车高速碰撞工况下，该区域的结构强度不足、变形较大，难以保证车内乘员的安全。

下面参考图1至图4描述根据本申请实施例的前围板的加强板300。
本申请实施例提供了一种前围板100的加强板300，图1示出了该加强板300的结构，图2示出了该加强板300的安装位置及安装环境。根据本申请实施例的前围板的加强板300，如图1和图2所示，该加强板300包括：加强板本体30和连接翻边40。
加强板本体30位于车辆1000的前围板100和挡板组件200之间，并被配置为支撑前围板100和挡板组件200。连接翻边40与加强板本体30相连，且连接翻边40的外侧面401分别与前围板100和挡板组件200相连。其中，加强板本体30具有第一加强筋51，和/或，连接翻边40具有第二加强筋52。
具体地，连接翻边40具有外侧面401，该外侧面401包括朝向前围板100的部分，以及朝向挡板组件200的部分。加强板本体30通过连接翻边40的外侧面401与前围板100和挡板组件200分别相连，这样使加强板本体30与前围板100和挡板组件200连接成一个整体，从而使得前围板100和挡板组件200在受到横向冲击力时不易变形，因此提高了前围板100和挡板组件200之间区域的结构强度，减小了整车高速碰撞工况下该区域的变形。并且，由于加强板 本体30和/或连接翻边40上分别设有第一加强筋51和第二加强筋52，因此能够提高加强板300的结构强度，使得加强板300对前围板100和挡板组件200之间区域的结构强度的提升作用更加显著。
需要说明的是，挡板组件200和加强板300均位于前围板100的外侧，并且挡板组件200位于加强板300远离前围板100的一侧。
在相关技术中，为了配合车辆1000地板下部动力电池的布置需求，在前围板100的外侧设置有挡板组件200，该挡板组件200与前围板100相配合而围成一个横向的三角形空腔，该三角形空腔易于在高速碰撞所产生的横向冲击力下发生变形，很难为车辆1000的乘员舱提供有效的碰撞缓冲及保护。
在本申请实施例中，加强板300在上述空腔中的安装方向与挡板组件200被冲击时的可能受力方向相同或夹角较小，但是加强板300在上述空腔中的安装方向不能垂直于挡板组件200被冲击时的可能受力方向。
示例性地，挡板组件200最容易受到横向的冲击力，并且挡板组件200和前围板100之间的区域对该横向冲击力的抵抗能力较差。因此，加强板300在该空腔中可以沿横向设置。在整车碰撞时，挡板组件200会先受到横向的冲击力，在空腔中横向设置的加强板300能够为挡板组件200提供支撑，使得挡板组件200不容易变形，同时加强板300的设置也能够减小前围板100变形的概率。
为了进一步提高加强板300对挡板组件200和前围板100的支撑效果，加强板300上还具有至少一个加强筋50，该加强筋50用于提高加强板300的结构强度。如图1所示，加强筋50包括第一加强筋51和第二加强筋52中的至少一种，其中第一加强筋51是形成于加强板本体30上的加强筋，第二加强筋52是形成于连接翻边40上的加强筋。
示例性地，加强板本体30具有第一加强筋51，连接翻边40不具有加强筋50；或者，连接翻边40具有第二加强筋52，加强板本体30不具有加强筋50；再或者，加强板本体30具有第一加强筋51，连接翻边40具有第二加强筋52。
如图1所示，加强板本体30和连接翻边40均具有加强筋50。相比于没有加强筋50的加强板300，具有加强筋50的加强板300，对挡板组件200和前围板100的加强效果更好。
可选地，第一加强筋51的数量为至少一条，和/或，第二加强筋52的数量 为至少一条。
在一些实施例中，如图1所示，加强板本体30包括第一本体部31和第一加强部32，第一本体部31和第一加强部32相连，第一加强部32的至少一部分的厚度大于第一本体部31的厚度，第一加强筋51形成于第一加强部32。
可以理解的是，由于第一加强部32具有厚度大于第一本体部31的厚度的部分，因此该部分会相对于第一本体部31的表面凸出，该凸出的部分即为形成在第一加强部32上的第一加强筋51。也即是说，第一加强筋51通过增加加强板本体30的部分区域的厚度形成，并且由于该区域的厚度更厚，因此增强了加强板本体30的结构强度。同时，由于第一加强筋51、第一加强部32和第一本体部31为一体成型结构，因此能够提高加强板本体30的生产效率，进而提高加强板300的生产效率。
可选地，如图1所示，第一加强筋51的延伸方向与挡板组件200受到冲击力时的受力方向相同。示例性地，挡板组件200最容易受到横向的冲击力，并且挡板组件200和前围板100之间的区域对该横向冲击力的抵抗能力较差。因此，加强板300在该空腔中可以沿横向设置，并且第一加强筋51沿横向延伸。
在一些实施例中，如图1和图2所示，连接翻边40包括第一翻边41和第二翻边42，第一翻边41和挡板组件200焊接相连，第二翻边42和前围板100粘接相连。
示例性地，在加强板300连接的过程中，先将第二翻边42与前围板100粘接相连，这样能够将加强板300初步固定在前围板100上；之后再将挡板组件200和第一翻边41焊接相连，从而将加强板300固定在挡板组件200上，并最终实现加强板300在前围板100和挡板组件200之间的牢固固定。
可选地，加强板300的第二翻边42通过结构胶与前围板100粘接。这样能够在粘接过程中根据需求调整第二翻边42在前围板100上的粘接位置，之后再将第一翻边41与挡板组件200焊接，从而使得连接更加稳定，定位更加准确。
在一些实施例中，如图1所示，挡板组件200包括前部挡板21和底部挡板22；前部挡板21和底部挡板22弯折相连，并且前部挡板21远离底部挡板22的一侧与前围板100连接，底部挡板22远离前部挡板21的一侧与前围板100连接，从而在前部挡板21、底部挡板22和前围板100之间围成三角形空腔。
在一些实施例中，继续参见图1，第一翻边41包括第一板体411和第二板 体412，第一板体411和第二板体412沿加强板本体30的周向间隔设置，其中第一板体411和前部挡板21相连，第二板体412和底部挡板22相连。
需要说明的是，为了满足前部挡板21自身在车辆上的空间布置需求，以及与前围板100的连接需求，前部挡板21具有一个弯折处，基于该弯折处，前部挡板21可以被划分为两个板体，这两个板体在该弯折处构成夹角。
为了适配前部挡板21的上述结构，第一板体411包括两个小板，这两个小板与前部挡板21的两个板体的侧壁分别相连，以使第一板体411能与前部挡板21以更贴合的方式进行连接。同时，第二板体412和底部挡板22相连，从而挡板组件200整体上与第一翻边41连接得更加牢固和可靠，连接效果更好。
在一些实施例中，如图1所示，第二板体412包括第二本体部4121和第二加强部4122，第二本体部4121与第二加强部相连4122，第二加强部4122的至少一部分的厚度大于第二本体部4121的厚度，第二加强筋52形成于第二加强部4122。
可以理解的是，由于第二加强部4122具有厚度大于第二本体部4121的厚度的部分，因此该部分会相对于第二本体部4121的表面凸出，该凸出的部分即为形成在第二加强部4122上的第二加强筋52。也即是说，第二加强筋52通过增加第二板体412的部分区域的厚度形成，并且由于该区域的厚度更厚，因此增强了第二板体412的结构强度，进而增强了连接翻边40的结构强度。
由此，第二加强部4122形成的第二加强筋52使得第二板体412的结构强度更高，能对挡板组件200提供更好的支撑。同时，由于第二加强筋52、第二加强部4122和第二本体部4121为一体成型结构，因此能够提高第二板体412的加工效率，进而提高加强板300的生产效率。
在一些实施例中，如图1所示，第二板体412上设有安装孔4123，该安装孔4123被配置为与车辆1000的动力电池的安装框架固定连接。
一些示例中，车辆1000的动力电池的连接结构会穿过前围板100，与前围板100前部的挡板组件200相连，例如与底部挡板22上的连接点相连。设置在第二板体412上的安装孔4123，与底部挡板22上的连接点的位置相重合，从而在安装动力电池时，动力电池的连接结构会依次穿过前围板100和设置在第二板体412上的安装孔4123，以实现与底部挡板22上的连接点相连。
由此，第二板体412在对底部挡板22加强的同时，还能够对车辆1000的 动力电池的安装框架进行结构加强，使得动力电池安装的更加稳固。
在一些实施例中，如图1所示，第一板体411、第二板体412和第二翻边42沿加强板本体30的周向分布，并彼此间隔。
基于上述设置，加强板本体30与挡板组件200和前围板100之间的连接点的数量更多，因此能够更好的将加强板300固定在挡板组件200和前围板100上。同时，由于第一板体411、第二板体412和第二翻边42在加强板本体30周向上分布，因此在挡板组件200受到冲击力时，加强板300的受力和传力都会更加均匀，从而使得前围板100和挡板组件200之间区域更加不易变形。
在一些实施例中，如图1和图2所示，连接翻边40与加强板本体30弯折相连。
通过将连接翻边40与加强板本体30弯折相连，连接翻边40朝向挡板组件200和前围板100的外侧面401的面积相对较大，进而连接翻边40与挡板组件200和前围板100的连接面积更大，连接效果更好。
本申请还提供了一种前围板组件，该前围板组件的结构如图2所示。参见图2，本申请实施例的前围板组件包括：前围板100、挡板组件200和上述的加强板300。其中，挡板组件200安装于前围板100的外侧，且挡板组件200和前围板100限定出安装腔。加强板300安装于安装腔内。
需要说明的是，前围板组件的安装腔即为上述的三角形空腔。
本申请实施例提供的前围板组件，在前围板100和挡板组件200之间安装有加强板300，因此能够增强前围板100和挡板组件200之间区域的结构刚强度，且加强板本体30具有第一加强筋51，和/或，连接翻边40具有第二加强筋52，因此该加强板300的强度得到强化，由利于进一步地提升前围板100和挡板组件200之间区域的结构刚强度，减小整车高速碰撞工况下该区域的变形，提高车辆安全性
可选地，该前围板组件可以包括多个加强板300。
在一些示例中，多个加强板300在该安装腔内沿安装腔的贯通方向依次分布，使得前围板组件的结构强度得到进一步的增强。其中，安装腔的贯通方向垂直于安装腔的横向。
在一些示例中，当前围板组件的安装腔的横向宽度进一步增加时，多个加 强板300在安装腔内阵列排布，并且沿安装腔的横向，至少两个加强板300依次相连或相抵，从而使得多个加强板300能对前围板组件的结构强度进一步加强。
在本申请实施例中，加强板300的具体数量可以根据实际需要进行选择，应理解的是，加强板300的数量越多，前围板组件的结构强度越好，挡板组件200、前围板100和安装腔越不容易变形。
本申请还提出一种车辆1000，该车辆包括上述实施例所述的前围板组件。
本申请实施例提供的车辆，由于其在前围板100和挡板组件200之间安装有加强板300，因此能够增强前围板100和挡板组件200之间区域的结构刚强度，且加强板本体30具有第一加强筋51，和/或，连接翻边40具有第二加强筋52，因此该加强板300的强度得到强化，由利于进一步地提升前围板100和挡板组件200之间区域的结构刚强度，减小整车高速碰撞工况下该区域的变形，提高车辆安全性。
可选地，车辆1000为电动汽车。电动汽车的地板不存在中央通道结构，并且地板上需要布置动力电池，动力电池在安装过程中，其连接点会贯穿前围板100，故需要在前围板100的外侧安装挡板组件200，从而为动力电池的连接点提供安装区域。
根据本申请实施例的车辆1000，车辆1000安装有上述实施例中的前围板组件，其中该前围板组件在车辆1000上的安装位置如图4所示。
在前围板组件中，加强板300安装在前围板100和挡板组件200之间，使得加强板300能够增强前围板100和挡板组件200之间区域的结构刚强度，且加强板本体30和/或连接翻边40上设有加强筋50，能够使进一步增强加强板300的强度，利于进一步地提升前围板100和挡板组件200之间区域的结构刚强度，减小整车高速碰撞工况下该区域的变形，提高车辆的安全性。
参见图1至图4，本申请实施例还提供了一种前围板100的加强板300，包括：加强板本体30和连接翻边40，加强板本体30支撑于车辆1000的前围板100和挡板组件200之间，连接翻边40与加强板本体30相连，且连接翻边40的外侧面分别与前围板100和挡板组件200相连。其中，加强板本体30和/或连 接翻边40设有加强筋50。
根据本申请实施例的前围板的加强板300，加强板300能够安装在前围板100和挡板组件200之间，使得加强板300能够增强前围板100和挡板组件200之间区域的结构刚强度，且加强板本体30和/或连接翻边40上设有加强筋50，能够使进一步增强加强板300的强度，利于进一步地提升前围板100和挡板组件200之间区域的结构刚强度，减小整车高速碰撞工况下该区域的变形。
