本申请属于车辆技术领域，尤其涉及一种车辆的副车架及车辆。
背景技术
随着技术的发展，汽车的使用不断普及，故保证汽车的使用可靠性是汽车领域中研究的重点。而副车架作为汽车的悬架系统的重要组成部分，能够为悬架系统提供主要的支撑结构，如控制臂、稳定杆、转向器等零件的安装点。如何改进副车架的结构、提高汽车的可靠性，是车辆技术领域的一个重要研究方向。
发明内容
本申请实施方式提供了一种车辆的副车架及车辆，便于副车架处释放碰撞吸能空间。
本申请实施方式的第一方面，提供了一种车辆的副车架，包括车架本体、支架和连接件。支架包括相对的第一端和第二端，第一端用于与车架本体连接。连接件连接于第二端，连接件设有连接孔，连接孔沿第一方向贯穿连接件，且连接孔延伸至连接件沿第二方向的边缘并形成开口，第一方向平行于支架的高度方向，第一方向垂直于第二方向。
采用上述结构，通过使连接孔延伸至连接件沿第二方向的边缘并形成开口，能够使连接孔上具有承力薄弱点，在副车架上承受较大外力时，便于连接孔处变形，使处于连接孔内的安装件与连接件相脱离，从而实现副车架与车身的分离，使副车架能够正常为车辆提供碰撞吸能空间，提高车辆的使用可靠性。
在本申请的一些可选实施方式中，车架本体包括两个纵梁和两个横梁，两个纵梁沿第二方向间隔设置，两个横梁沿第三方向间隔设置，两个横梁位于两个纵梁之间并分别连接于两个纵梁，第三方向垂于第一方向和第二方向，第一端与纵梁沿第一方向的上表面相连接。
采用上述结构，首先，通过设置两个纵梁和两个横梁，能够为车架本体提供稳定的框架结构，便于在车架本体上设置悬架系统的安装点，其次，通过使第一端与纵梁上沿第一方向的上表面相连接，能够便于车架本体通过支架与车身纵梁相连接。
在本申请的一些可选实施方式中，纵梁上沿第一方向的上表面上设置有凹槽，在第一方向上凹槽朝向远离支架一侧凹陷，在第三方向上凹槽设置于第一端的一侧。
采用上述结构，通过在纵梁设置凹槽，能够使纵梁上具有承力薄弱点，在车架 本体受到沿第三方向上较大的外力时，便于纵梁从凹槽处溃折，为车辆提供碰撞吸能空间，同时使溃折时纵梁的弯折方向朝向远离连接件的一侧，降低纵梁溃折对车身内部结构的影响。
在本申请的一些可选实施方式中，连接孔包括本体部和连通部，连通部设置于本体部上第二方向的一侧，且连通部在第二方向上连通本体部和连接件的外部形成开口。
采用上述结构，通过设置本体部和连通部，能够使连接孔上具有相对独立的两部分，其中本体部满足连接孔中穿设安装件的需要，连通部满足连接孔上形成开口的需要。
在本申请的一些可选实施方式中，在垂直于第一方向的平面内，连通部的投影朝向远离凹槽投影的一侧倾斜。
采用上述结构，由于在第三方向上凹槽设置于支架的一侧，故在纵梁溃折时，支架上所受到的外力为朝向凹槽处的力，而根据力的相互作用关系可知，连接孔与穿设于其内的安装件相抵接时，所受外力为远离凹槽方向的力，此时将连通部的朝向远离凹槽的一侧倾斜，能够使连通部的延伸方向与实际作用时的受力方向相同，便于处于连接孔内的安装件与连接件相脱离。
在本申请的一些可选实施方式中，连接件包括平行设置的第一壁面和第二壁面，连通部形成于第一壁面和所述第二壁面之间，第一壁面平行于第一方向，且第一壁面与第二方向的相交。
采用上述结构，通过将连通部形成于平行设置的第一壁面和第二壁面之间，能够使连接部呈直线形，便于连通部承力张开，使处于连接孔内的安装件与连接件相脱离。
在本申请的一些可选实施方式中，第一壁面与第二方向的夹角为α，满足，0＜α≤45°。
采用上述结构，通过限制第一壁面与第二方向的夹角α的范围，能够使连通部的延伸方向贴合于实际作用时连接孔的受力方向，降低因夹角α过大或过小，导致的连通部承力能力提高，造成连接孔与安装件的分离难度增大。
在本申请的一些可选实施方式中，连接件还包括第三壁面和第四壁面，本体部的至少部分形成于第三壁面和第四壁面之间，第三壁面与第一壁面相连接，第二壁面与第四壁面相连接，在垂直于第一方向的平面内，第三壁面和第四壁面的投影呈直线。
采用上述结构，通过设置第三壁面和第四壁面，并使第三壁面和第四壁面为平面，能够使第一壁面、第二壁面、第三壁面及第四壁面共同构成的结构呈类漏斗状，便于本体部内的安装件通过连通部从连接孔内脱离。
在本申请的一些可选实施方式中，第三壁面与第四壁面延伸相交后的夹角为β，满足，0＜β＜180°。
采用上述结构，通过限制第三壁面与第四壁面延伸相交后的夹角β的范围，能够使第一壁面、第二壁面、第三壁面及第四壁面共同构成类漏斗状，具有稳定的尖角，便于将本体部内的安装件引导向连通部处，使安装件与较薄弱的连通部相抵接，便于 连通部承力张开。
在本申请的一些可选实施方式中，连接件还包括圆角面，第三壁面与第一壁面间，以及第四壁面与第二壁面间分别通过圆角面相连接。
采用上述结构，通过设置圆角面，一方面，能够使第三壁面与第一壁面间，以及第四壁面与第二壁面间的过渡更加平滑，便于将本体部内的安装件进入连通部，另一方面，也能够在连通部连通本体部的一侧形成喇叭口，便于本体部内的安装件与连通部相抵接。
在本申请的一些可选实施方式中，在垂直于第一方向的平面内，本体部的投影呈多边形，连通部在本体部任一角处与本体部相连通。
采用上述结构，通过使本体部的投影呈多边形，能够本体部形状较为规整，便于本体部成型，也使本体部上具有较多角结构，便于连通部设置。
在本申请的一些可选实施方式中，在垂直于第一方向的平面内，本体部的投影呈四边形，本体部的投影的两条对角线，分别与第二方向和第三方向相平行，连通部在本体部沿第二方向上的角处与本体部相连通。
采用上述结构，通过使本体部的投影呈四边形，并使本体部的投影的两条对角线，分别与第二方向和第三方向相平行，能够使本体部的结构更稳定，提高连接孔处的机械强度。
在本申请的一些可选实施方式中，支架包括两个，且两个支架的第一端分别与两个纵梁上沿第一方向的上表面相连接，连接件包括两个，且两个连接件分别与两个支架上的所述第二端相连接。

与相关技术相比，本申请实施方式的车辆的副车架及车辆中，通过使连接孔延伸至连接件沿第二方向的边缘并形成开口，能够使连接孔上具有承力薄弱点，在副车架上承受较大外力时，便于连接孔处变形，使处于连接孔内的安装件与连接件相脱离，从而实现副车架与车身的分离，使副车架能够正常为车辆提供碰撞吸能空间，提高车辆的使用可靠性。

具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
在本申请的描述中，需要说明的是，除非另有说明，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或组件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。“垂直”并不是严格意义上的垂直，而是在误差允许范围之内。“平行”并不是严格意义上的平行，而是在误差允许范围之内。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
在本申请的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本申请中的具体含义。
目前，从市场的发展来看，汽车的使用不断普及，而随着汽车技术的发展，市场对汽车的使用可靠性也提出了更高的要求，故汽车的使用可靠性是目前研究的重点之一。
相关技术中，通常汽车的悬架系统配置有副车架，如前悬架系统对应的前副车架，前副车架用于支撑前悬架系统，如提供控制臂、稳定杆、转向器、动力总成后悬置等零部件的安装点。为了加固前副车架与车身间的连接强度，前副车架上还设置有支架结构，用于与车身相连接，用于连接车身纵梁的中塔等。在前副车架通过支架结构与车身相连接后，支架为前副车架提供了稳定的拉力，造成车辆出现碰撞时，前副车架无法向远离车身的一侧折弯，导致不能充分释放碰撞空间，使碰撞容易侵入车身结构(如乘员舱)内，影响汽车的使用可靠性。
为了减少支架影响汽车的使用可靠性的问题，可以对支架的结构进行调整，使支架连接车身的一侧易承力变形，实现支架与车身的分离，如车身与支架间多通过紧固件相连接，而支架上通常提供紧固件连接用的通孔，可在通孔上形成薄弱区域，在支架承力后通孔的薄弱区域变形，使紧固件无法实现固定，有助于支架与车身的分离，充分释放副车架上的碰撞空间，提高汽车的使用可靠性。
基于以上考虑，设计了一种车辆的副车架及车辆。
本申请实施例提供了一种车辆，车辆可以为燃油汽车、燃气汽车或新能源汽车等，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。
以下实施例为了方便说明，以本申请一实施例的一种车辆为电动车辆1000为例进行说明。
图1为本申请一些实施例提供的车辆1000的结构示意图。
如图1所示，车辆1000的内部设置有电池100，电池100可以设置在车辆1000的底部或头部或尾部。电池100可以用于车辆1000的供电，例如，电池100可以作为车辆1000的操作电源。车辆1000还可以包括控制器200和电机300，控制器200用来控制电池100为电机300供电，电机300用于为车辆1000的移动提供驱动力，例如，用于车辆1000的启动、导航和行驶时的工作用电需求。
在本申请一些实施例中，电池100不仅可以作为车辆1000的操作电源，还可以作为车辆1000的驱动电源，代替或部分地代替燃油或天然气为车辆1000提供驱动动力。
本申请的实施例中，所提到的电池100是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池100可以包括电池模块或电池包等。
图2为本申请一些实施例提供的车辆的副车架的结构示意图，图3为本申请一些实施例提供的支架20的结构示意图，图4为本申请一些实施例提供的连接件30处的俯视结构示意图。
如图2-图4所示，本申请的一些可选实施方式中，提供了一种车辆的副车架，包括车架本体10、支架20和连接件30。支架20包括相对的第一端21和第二端22，第一端21用于与车架本体10连接。连接件30连接于第二端22，连接件30设有连接孔31，连接孔31沿第一方向x贯穿连接件30，且连接孔31延伸至连接件30沿第二方向y的边缘32并形成开口33，第一方向x平行于支架20的高度方向，第一方向x垂直于第二方向y。
车辆的副车架可为车辆中用于支撑悬架系统的车架结构。本申请实施例的副车架可以为前副车架，也可以为后副车架。示例性地，本申请实施例的副车架可以是用于支撑前悬架系统的前副车架。
车架本体10可为副车架中最主要的承力结构，如车架本体10可以成板状、框架状或其它形状。
支架20可为副车架的连接车身的结构，如支架20可以是在第一方向上凸出于车架本体10的柱状结构、台状结构或杆状结构等。
连接件30可为位于支架20上，并用于支架20与车身相固定的口结构，如支架20与车身通过螺栓相连接时，连接件30可以是具有连接孔31的片状结构、台状结构或块状结构等。示例性地，为了降低连接件30占用的体积，和便于连接件30与支架20相连接，连接件30可以是具有连接孔31的片状结构。
通过使连接孔31延伸至连接件30沿第二方向y的边缘32并形成开口33，能够使连接孔31上具有承力薄弱点，在副车架上承受较大外力时，便于连接孔31处变形，使处于连接孔31内的安装件与连接件30相脱离，从而实现副车架与车身的分离，使副车架能够正常为车辆提供碰撞吸能空间，提高车辆的使用可靠性。
在一些实施例中，支架20可为高度沿第一方向x延伸的柱状结构，第一端21和第二端22为支架20上第一方向x的两端。
在一些实施例中，连接件30与支架20可以是一体成型，也可以是分体固定连接，如焊接、胶接、紧固件连接等。
在一些实施例中，支架20与车架本体10可以是一体成型，也可以是分体固定连接，如焊接、胶接等。
参照图4，在一些实施例中，第二端22可设置有安装槽221，连接件30通过安装槽221与第二端22相连接。
可以理解的是，连接孔31可以为正常的孔状结构，而在连接件30上设置其他薄弱结构，能够达到便于连接孔31被破坏即可，如连接件30上还可设置有薄弱区，在薄弱区内连接件30的厚度被削薄，且薄弱区的一端与连接孔31相接触，另一端延伸至连接件30上沿第二方向y的端部。
实际使用中，当车架本体10承受外力弯折时，支架20跟随车架本体10移动，此时穿设于连接孔31内的安装件与连接孔31内壁抵接，当抵接力超过连接孔31上开口侧的承力阈值时，连接孔31沿开口33被撑开，使孔结构被破坏，进而使支架20与车身相分离。
如图2-图4所示，在本申请的一些可选实施方式中，车架本体10包括两个纵梁11和两个横梁12，两个纵梁11沿第二方向y间隔设置，两个横梁12沿第三方向z间隔设置，两个横梁12位于两个纵梁11之间并分别连接于两个纵梁11，第三方向z垂于第一方向和第二方向，第一端21与纵梁11沿第一方向x的上表面112相连接。
示例性地，纵梁11指的是，沿车辆的宽度方向布设的两个支撑梁。
示例性地，横梁12指的是，沿车辆的宽度方向布设的两个支撑梁。
首先，通过设置两个纵梁11和两个横梁12，能够为车架本体10提供稳定的框架结构，便于在车架本体10上设置悬架系统的安装点，其次，通过使第一端21与纵梁11上沿第一方向x的上表面112相连接，能够便于车架本体10通过支架20与车身纵梁11相连接。
在一些实施例中，两个纵梁11和两个横梁12可呈井字形排布，并围合成方形区域。
在一些实施例中，方形区域内可设置有支撑板，用于构成车架本体10上提供支撑基础的构件，示例性地，支撑板可铺设于两个纵梁11和两个横梁12上。
如图2-图4所示，在本申请的一些可选实施方式中，纵梁11上沿第一方向x的上表面上设置有凹槽111，在第一方向x上凹槽111朝向远离支架20一侧凹陷，在第三方向z上凹槽111设置于第一端21的一侧。
通过在纵梁11设置凹槽111，能够使纵梁11上具有承力薄弱点，在车架本体10受到沿第三方向z上较大的外力时，便于纵梁11从凹槽111处溃折，为车辆提供碰撞吸能空间，同时使溃折时纵梁11的弯折方向朝向远离连接件30的一侧，降低纵梁11溃折对车身内部结构的影响。
在一些实施例中，纵梁11上沿第三方向z的一端朝向于车辆的车头，沿第三方向z的一端朝向于车辆的车尾，凹槽111设置于第一端21靠近于车头的一侧。
在一些实施例中，在第二方向y上，连接孔31上的部分延伸至连接件30上远离另一纵梁11的一侧连接件30的边缘并形成开口33。
如图2-图4所示，在本申请的一些可选实施方式中，连接孔31包括本体部311和连通部312，连通部312设置于本体部311上第二方向y的一侧，且连通部312在第二方向上连通本体部311和连接件30的外部形成开口33。
本体部311，可为连接孔31上孔型结构的主体，用于承担连接孔31穿设物体的职能。示例性地，支架20与车身间通过螺栓相连接时，螺栓穿设于本体部311内。
连通部312，可为连接孔31上用于在第二方向y上连通本体部311和连接件30的外部的部分。
通过设置本体部311和连通部312，能够使连接孔31上具有相对独立的两部分，其中本体部311满足连接孔31中穿设安装件的需要，连通部312满足连接孔31上形成开口的需要。
如图2-图4所示，在本申请的一些可选实施方式中，在垂直于第一方向x的平面内，连通部312的投影朝向远离凹槽111投影的一侧倾斜。
由于在第三方向z上凹槽111设置于支架20的一侧，故在纵梁11溃折时，支架20上所受到的外力为朝向凹槽111处的力，而根据力的相互作用关系可知，连接孔31与穿设于其内的安装件相抵接时，所受外力为远离凹槽111方向的力，此时将连通部312的朝向远离凹槽111的一侧倾斜，能够使连通部312的延伸方向与实际作用时的受力方向相同，便于处于连接孔31内的安装件与连接件30相脱离。
在一些实施例中，在垂直于第一方向x的平面内，连通部312的投影可以是朝向远离凹槽111投影的一侧倾斜的直线或者曲线。

通过将连通部312形成于平行设置的第一壁面313和第二壁面314之间，能够使连接部呈直线形，便于连通部312承力张开，使处于连接孔31内的安装件与连接件30相脱离。
可以理解的是，第一壁面313为连通部312一侧的侧壁，第二壁面314为连通部312另一侧的侧壁。
如图2-图4所示，在本申请的一些可选实施方式中，第一壁面313与第二方向y的夹角为α，满足，0＜α≤45°。
通过限制第一壁面313与第二方向y的夹角α的范围，能够使连通部312的延伸方向贴合于实际作用时连接孔31的受力方向，降低因夹角α过大或过小，导致的连通部312承力能力提高，造成连接孔31与安装件的分离难度增大。
在一些实施例中，第一壁面313与第二方向y的夹角为α，满足，5°≤α≤45°、10°≤α≤40°、15°≤α≤35°、20°≤α≤30°或25°≤α≤30°。

通过限制第三壁面316与第四壁面317延伸相交后的夹角β的范围，能够使第一壁面313、第二壁面314、第三壁面316及第四壁面317共同构成类漏斗状，具有稳定的尖角，便于将本体部311内的安装件引导向连通部312处，使安装件与较薄弱的连通部312相抵接，便于连通部312承力张开。
在一些实施例中，第三壁面316与第四壁面317延伸相交后的夹角为β，满足，10°≤β≤170°、20°≤β≤160°、30°≤β≤150°、40°≤β≤140°、50°≤β≤130°、60°≤β≤120°、70°≤β≤110°、80°≤β≤100°或90°≤β≤100°。
如图2-图4所示，在本申请的一些可选实施方式中，连接件30还包括圆角面315，第三壁面316与第一壁面313间，以及第四壁面317与第二壁面314间分别通过圆角面315相连接。

在一些实施例中，圆角面315可设置有两个，分别设置于第三壁面316与第一壁面313间，以及第四壁面317与第二壁面314间。
在一些实施例中，圆角面315为凸圆角面。
如图2-图4所示，在本申请的一些可选实施方式中，在垂直于第一方向x的平面内，本体部311的投影呈多边形，连通部312在本体部311任一角处与本体部311相连通。
通过使本体部311的投影呈多边形，能够本体部311形状较为规整，便于本体 部311成型，也使本体部311上具有较多角结构，便于连通部312设置。
在一些实施例中，在垂直于第一方向x的平面内，本体部311的投影可以是三角形、矩形、五边形、六边形等。
