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，仅用于解释本申请，而不能理解为对本申请的限制。
铸造件的应用非常广泛，真空高压铸铝可以快速成型，提高生产效率，但真空高压铸铝更适合薄壁类产品，未能够实现空心结构，导致结构强度和刚度差，并且，当铸造件应用于车辆的副车架时，由于未能够实现空心结构，降低了副车架的NVH(噪声、振动与声振粗糙度)、动静刚度及强度、耐久等性能。
此外，虽然低压铸铝工艺可以在副车架中实现空心结构，但低压铸铝工艺制造副车架时生产效率低、需要大量复制模具、生产设备和场地投入投资成本高。
因此，如何在高压铸铝副车架中实现空心结构，提高副车架的结构强度和刚度，降低副 车架的制造成本，提高副车架的制造效率，成为了本领域亟待解决的问题。
下面参考图1-图4描述根据本申请实施例的铸造件200。
根据本申请的铸造件200包括：基体梁1和压铸部，基体梁1内部形成有结构空腔；压铸部设置于基体梁1的至少部分外周并与基体梁1铸造为一体件。
需要说明的是，本申请所提出的铸造件200可以用于但不限于副车架、纵梁、横梁、门槛梁等，本申请以铸造件200用于副车架为例进行表述。
为了提高铝副车架的制造效率，降低铝副车架的制造成本，本申请中的铝副车架采用高压铸铝工艺制造而成，为了解决传统的高压铸铝工艺无法实现空心结构的问题，本申请中的铸造件200由基体梁1和压铸部组成，基体梁1内设置有结构空腔，结构空腔在基体梁1长度方向上贯穿基体梁1，使得基体梁1内部构造为空心结构，结构空腔还具有减重作用，减小基体梁的质量，将基体梁1预埋进模具中，再采用高压铸铝工艺，将铸造部包裹于基体梁1的至少部分外周，并使得铸造部与基体梁1构造为一体结构，使得铸造件200内部构造为空心结构，从而提高了铸造件200的结构强度和刚度，并且，当铸造件200设置于副车架上时，实现了在高压铸铝副车架上设置空心结构，从而提高了副车架的结构强度和刚度，以及有效改善了副车架的NVH(噪声、振动与声振粗糙度)性能，提升了车辆运行时的稳性和可靠性。
此外，本申请中可以实现在高压铸铝工艺设置空心结构，可以将本申请中的高压铸铝工艺应用于副车架和车辆中，提高了副车架的生产效率、减少了生产设备和场地投入投资成本、降低了生产制造成本，从而解决了低压铸铝工艺制造副车架时生产效率低、需要大量复制模具和生产设备、场地投入投资成本高的问题。
根据本申请的铸造件200通过在基体梁1内设置有结构空腔，结构空腔在基体梁1长度方向上贯穿基体梁1，使得基体梁1内部构造为空心结构，将基体梁1预埋进模具中，再采用高压铸铝工艺，将铸造部包裹于基体梁1的至少部分外周，且铸造部与基体梁1构造为一体结构，使得铸造件200内部构造为空心结构，从而提高了铸造件200的结构强度和刚度，并且，当铸造件200设置于副车架上时，实现了在高压铸铝副车架上设置空心结构，从而提高了副车架的结构强度和刚度，以及有效改善了副车架的NVH(噪声、振动与声振粗糙度)性能，提升了车辆运行时的稳性和可靠性。
根据本申请的一些实施例，压铸部包括：铸造包覆体11、第一加强筋12和第二加强筋13，铸造包覆体11设置于基体梁1的至少部分外周；第一加强筋12和第二加强筋13设置于铸造包覆体11，第一加强筋12和第二加强筋13分别沿基体梁1的长度方向延伸且彼此间隔设置。
在一些具体实施例中，压铸部由铸造包覆体11、第一加强筋12和第二加强筋13组成， 铸造包覆体11包裹于基体梁1的至少部分外周，铸造包覆体11将压铸部与基体梁1相连接，铸造包覆体11可以增加基体梁1的整体壁厚，提高了基体梁1的结构强度和刚度，提升了基体梁1的承重能力，在高压铸铝过程中，使得铸造包覆体11可以与基体梁1融为一体结构，进一步提高了压铸部与基体梁1连接的稳定性和可靠性。
第一加强筋12和第二加强筋13分别设置于铸造包覆体11宽度方向上的两侧，并沿基体梁1的长度方向延伸，增大了第一加强筋12、第二加强筋13与铸造包覆体11的连接面积，当基体梁1受到外力作用时，力能够更均匀快速的分布至第一加强筋12和第二加强筋13上，有效防止基体梁1某处受力过大而发生变形，提高了基体梁1的结构强度和刚度；应用于副车架时，第一加强筋12和第二加强筋13还能够将铸造件200与副车架上的其他结构连接在一起。
第一加强筋12、第二加强筋13和铸造包覆体11可以构造为一体结构，一方面使得第一加强筋12和第二加强筋13与铸造包覆体11的连接处不存在缝隙，提高了第一加强筋12、和第二加强筋13与铸造包覆体11之间连接的稳定性和可靠性，另一方面第一加强筋12、第二加强筋13和铸造包覆体11可以通过同一模具打造出来，减少了开模数量与制造步骤，降低了制造成本。
根据本申请的一些实施例，压铸部还包括：第三加强筋14，第三加强筋14设置于铸造包覆体11且第三加强筋14分别与第一加强筋12和第二加强筋13相连。
在一些实施例中，压铸部上还设置有第三加强筋14，第三加强筋14设置于铸造包覆体11的至少部分外周，第三加强筋14的一端与第一加强筋12相连接，第三加强筋14的另一端与第二加强筋13相连接，一方面能够在不加大铸造件200整体厚度的情况下，增强铸造件200的结构强度和刚度，使得铸造件200在受到外力作用时能够更好地保持稳定性和形状完整性；另一方面通过在铸造包覆体11表面设置第三加强筋14，当铸造件200受到外力作用时，第三加强筋14可以替铸造件200分担一部分力，同时力还可以通过第三加强筋14传导至第一加强筋12和第二加强筋13上，使得铸造件200受力分布更加均匀，减小铸造件200中的应力集中现象，可以提高铸造件200的抗弯和抗压能力，有效防止铸造件200受力变形。
根据本申请的一些实施例，第一加强筋12和第二加强筋13构造为在基体梁1第一方向上间隔设置，第一加强筋12在第二方向上的第一端和第二加强筋13在第二方向上的第一端连接；和/或第一加强筋12在第二方向上的第二端和第二加强筋13在第二方向上的第二端连接以围成朝向背离基体梁1敞开的体腔。
在一些具体实施例中，基体梁1第一方向上的一侧设置有第一加强筋12，基体梁1第一方向上的另一侧设置有第二加强筋13，第一加强筋12与第二加强筋13间隔设置，第一 加强筋12在第二方向上分别形成有第一端和第二端，第二加强筋13在第二方向上分别形成有第一端和第二端，第一加强筋12的第一端与第二加强筋13的第一端设置于同一侧，第一加强筋12的第二端与第二加强筋13的第二端设置于同一侧，且第一加强筋12的第一端与第二加强筋13的第一端相连接，第一加强筋12的第二端与第二加强筋13的第二端相连接，第一加强筋12、第二加强筋13和铸造包覆体11共同限定出敞开的腔体，敞开的腔体内可以用于收容第三加强筋14，腔体朝向背离基体梁1的方向敞开，第一加强筋12和第二加强筋13之间组成一个顶部敞开的腔体，使得第一加强筋12和第二加强筋13可以承载更多的力，进一步加强了铸造件200的结构强度和刚度。
在另一些实施例中，第一加强筋12的第一端与第二加强筋13的第一端相连接，第一加强筋12的第二端与第二加强筋13的第二端正对且间隔设置，且第一加强筋12的第二端和第二加强筋13的第二端分别延伸，以在第一加强筋12的第二端形成有沿第一方向延伸的第一延伸部121，第二加强筋13的第二端形成有沿第一方向延伸的第二延伸部131，第一延伸部121与第二延伸部131平行设置，使得第一加强筋12和第二加强筋13围成的腔体结构更加稳定，应用于副车架时，第一加强筋12和第二加强筋13可以通过第一延伸部121和第二延伸部131将基体梁1受到的力从两个不同的方向传递给副车架上的其他部件，进一步加强了铸造件200的抗冲击以及承力能力。应当理解的是，此处沿第一方向延伸并不局限于延伸方向必须与第一方向平行，其可以是延伸方向与第一方向成一定夹角，也可以是延伸方向与第一方向平行。
根据本申请的一些实施例，第三加强筋14收容于腔体内且构造为在基体梁1延伸方向上依次布置的多个。
在一些具体实施例中，第三加强筋14可以设置于腔体的内壁上，第三加强筋14可以构造为在基体梁1延伸方向上彼此交错布置的多个，在腔体内壁上设置多个彼此交错的第三加强筋14可以进一步提高铸造件200的结构强度和刚度，至少相邻两个第三加强筋14之间相交并形成交点，使得第三加强筋14能够在多个不同方向上实现对铸造件200结构的加强，相交设置的第三加强筋14可以互相平均承担受到的力，使得多个第三加强筋14受力更加均衡，由于多个第三加强筋14的延伸方向不同，可以将铸造件200受到的力传导至不同方向，进一步加强了铸造件200的结构强度和刚度，提高了铸造件200的耐冲击性。
在另一些具体实施例中，第三加强筋14可以构造为在基体梁1延伸方向上彼此平行设置的多个，多个彼此平行设置的第三加强筋14可以在铸造件200受到外力作用时，将力更加均衡稳定地沿同一方向传导至第一加强筋12和第二加强筋13的不同位置，从而提高了铸造件200的抗冲击能力，进一步加强了铸造件200的结构强度和刚度。
根据本申请的一些实施例，多个第三加强筋14在基体梁1的延伸方向上依次相连，相 邻的两个第三加强筋14在第二方向上靠近彼此的端部与第一加强筋12和与第二加强筋13的中一个连接，相邻的两个第三加强筋在第二方向上远离彼此的端部与第一加强筋12和第二加强筋13中的另一个连接，一方面使得其中一个第三加强筋14受到的力可以快速的传递给其他的第三加强筋14，使得力可以均匀的在多个第三加强筋14之间传递，有效防止任一个第三加强筋14受力过大断裂，另一方面，力在多个加强筋之间传递的同时，力还能通过多个第三加强筋14与第一加强筋12和第二加强筋13之间的连接处，传递给第一加强筋12和第二加强筋13，进一步加强了铸造件200的结构强度和刚度，提高了铸造件200的耐冲击性。
根据本申请的一些实施例，基体梁1构造为管状，且基体梁1的横截面构造为圆形、多边、曲线围成的图形或由直线与曲线组合围成的图形。
在一些具体实施例中，基体梁1可以构造为圆形管，基体梁1外周壁的横截面可以构造为圆形，相比于其他形状的管道，圆形管具有更均匀的强度分布，由于圆形管的圆形截面对压力的分布具有优势，圆形管能够更有效地承受内外部压力，减少应力集中，提高铸造件200的强度和稳定性。
基体梁1还可以构造为矩形管，基体梁1构造为矩形管，基体梁1外周壁的横截面可以构造为矩形，相比于其他形状的管道，矩形管具有更大的横截面积，因而在相同负载下能够承受更大的力，还能够保证结构的稳定性，较大的横截面积还可以提供更大的刚性和稳定性，减少副车架100在行驶过程中的振动和结构共振现象，提升了副车架100的NVH(噪声、振动与声振粗糙度)性能。
基体梁1的横截面还能构造为由直线与曲线组合围成的图形，例如，基体梁1的横截面可以由两部分组成，其中一部分可以构造为圆弧形，其中另一部分可以构造为多边形。
基体梁1的横截面还能够构造为不规则图形，例如基体梁1的横截面可以构造为凹字型或凸字型等其他不规则截面形状。
下面简单描述根据本申请的副车架100。
根据本申请的副车架100包括：第一横梁21、第二横梁22、第一纵梁23和第二纵梁24，第一横梁21和第二横梁22在第一方向上间隔设置，第一纵梁23分别与第一横梁21在第二方向上的第一端和第二横梁22在第二方向上的第一端连接，第二纵梁24分别与第一横梁在第二方向上的第二端和第二横梁22在第二方向上的第二端连接；其中第一横梁21、第二横梁22、第一纵梁23和/或第二纵梁24构造为上述实施例中任意一项所述的铸造件200，因此根据本申请的副车架100的第一横梁21、第二横梁22、第一纵梁23或第二纵梁24都可以通过高压铸铝工艺铸造为空心结构，从而提高副车架100的结构刚度和强度，以及提升了副车架100的NVH(噪声、振动与声振粗糙度)性能。
下面简单描述根据本申请的副车架100的制造方法。
在一些具体实施例中，首先根据所需副车架100的参数对基体梁1进行单独加工(基体梁1的制造材料和形状可以根据产品需要进行变更)，将加工好的基体梁1预埋进模具中，模具中一般设置有限位与固定结构，以限制基体梁1位于模具内的运动，基体梁1放置在模具中设计位置固定完毕后，合模采用抽真空高压铸铝工艺进行压铸，铸造完毕后根据需要切除多余的端头处的基体梁1，从而获得了设置有空心结构的副车架100。
根据本申请的一些实施例，第一横梁21上形成有在第二方向上延伸的基体梁1，结构空腔在第二方向上贯通基体梁1，第二方向与第一方向正交，第二方向为第一横梁21的长度方向，第一方向为第一横梁21的宽度方向，使得第一横梁21内部构造为空心结构，与传统的副车架100第一横梁21构造为薄壁结构相比，本申请的第一横梁21的结构强度和刚度更高，从而提高了副车架100的结构强度和刚度，以及提升了副车架100的NVH(噪声、振动与声振粗糙度)性能。
在一些具体实施例中，第一纵梁23和第二纵梁24上还设置有多个起到安装或避让或减重作用的孔，可以减轻副车架100整体重量的同时，还能够方便其他零部件的装配。
下面简单描述根据本申请的车辆。
