下面结合附图并参考具体实施例描述本发明。
首先结合图1-图4描述本发明实施例的发动机舱框架100。
如图1-图4所示,本发明实施例的发动机舱框架100可以包括前部框架101、上部框架102和下部框架103,上部框架102的前端可以与前部框架101的上端连接,且上部框架102可以位于前部框架101的后侧,下部框架103的前端可以与前部框架101的下端连接,且下部框架103可以位于前部框架101的后侧。
可以理解的是,下部框架103可以位于上部框架102的下方,由此,下部框架103、前部框架101与上部框架102可以共同形成开口向后的容纳空间,车辆的发动机等零部件可以设置在容纳空间内。
由此,发动机舱框架100可以分为下部框架103、前部框架101与上部框架102三个模块,人员在装配发动机舱框架100前,可以预先将不同截面的型材通过焊接或铆接制成前部框架101、上部框架102和下部框架103。
人员在装配发动机舱框架100时,可以直接将下部框架103、前部框架101与上部框架102焊接或铆接在一起,进而完成发动机舱框架100的装配。相对于传统的发动机舱框架100,减少了发动机舱框架100装配时所需的零件数量,节约了发动机舱框架100的装配时间,发动机舱框架100的装配更容易。
根据本发明实施例的发动机舱框架100,通过设置下部框架103、前部框 架101与上部框架102,使发动机舱结构模块化,减少了发动机舱框架100装配时所需的零件数量,节约了发动机舱框架100的装配时间,降低发动机舱框架100的开发成本,发动机舱框架100的装配更容易。
在一些优选的实施例中,如图2所示,前部框架101可以包括左立柱1011、右立柱1012和多个连接横梁,左立柱1011可以和右立柱1012左右间隔开布置,左立柱1011可以沿上下方向设置且构成前部框架101的左侧边,右立柱1012可以沿上下方向设置且构成前部框架101的右侧边,多个连接横梁可以连接在左立柱1011和右立柱1012之间,从而多个连接横梁可以支撑左立柱1011和右立柱1012。
在一些具体的实施例中,如图2所示,多个连接横梁可以包括上横梁1013、下横梁1015和中间横梁1014,上横梁1013可以分别与左立柱1011的上端以及右立柱1012的上端连接,下横梁1015可以分别与左立柱1011的下端以及右立柱1012的下端连接,由此,上横梁1013、左立柱1011、上横梁1013和右立柱1012的端点可以依次连接构成四边形。
如图2所示,中间横梁1014可以分别与左立柱1011和右立柱1012相连且位于上横梁1013和下横梁1015之间,中间横梁1014可以增加前部框架101整体的结构强度。
具体地,如图2所示,前部框架101还可以包括两个吸能盒1016,两个吸能盒1016可以分别位于下横梁1015与左立柱1011的连接处的前表面以及下横梁1015与右立柱1012的连接处的前表面,即两个吸能盒1016可以分别位于前部框架101的左下角和右下角。
在一些更加具体的实施例中,如图2所示,上横梁1013、下横梁1015可以与中间横梁1014互相平行,从而使前部框架101整体的结构更加稳定。
在一些更加具体的实施例中,如图2所示,左立柱1011的下部与右立柱1012的下部均可以为直梁,左立柱1011的直梁部分可以与右立柱1012的直梁部分互相平行,左立柱1011的上部与右立柱1012的上部均可以为弧形梁,且左立柱1011的弧形梁部分与右立柱1012的弧形梁部分之间的距离从下向上可以逐渐增大,即左立柱1011的弧形梁部分与右立柱1012的弧形梁部分从下向上逐渐相对背离。
由此,当前部框架101下方的吸能盒1016受到撞击时,左立柱1011和右立柱1012可以进而向上分散受到的撞击力,减少发动机舱框架100的变形程度。
在一些更加具体的实施例中,如图2所示,由于在左立柱1011与右立柱1012中,直梁与弧形梁的交界处的强度较低,中间横梁1014可以连接在左立柱1011的直梁与弧形梁的交界处以及右立柱1012的直梁与弧形梁的交界处之间,由此中间横梁1014具有支撑作用,即中间横梁1014增加了左立柱1011与右立柱1012中的直梁与弧形梁的交界处的强度。
可以理解的是,左立柱1011与右立柱1012的弧形梁部分可以位于中间横梁1014与上横梁1013之间,左立柱1011与右立柱1012的直梁部分可以位于中间横梁1014与下横梁1015之间。
由此,在一些更加具体的实施例中,如图2所示,中间横梁1014与上横梁1013之间的距离可以小于中间横梁1014与下横梁1015之间的距离,由此可以增加连接横梁对左立柱1011与右立柱1012的弧形梁部分的支撑,提高左立柱1011与右立柱1012的弧形梁部分的强度。
在一些具体的实施例中,如图3所示,上部框架102可以包括左边梁1021、右边梁1022和后横梁1023,左边梁1021和右边梁1022左右可以间隔开布置, 左边梁1021可以沿前后方向设置且构成上部框架102的左侧边,右边梁1022可以沿前后方向设置且构成上部框架102的右侧边,左边梁1021的后端与右边梁1022的后端可以分别与车辆的驾驶舱框架连接。
如图3所示,左边梁1021的前端可以与左立柱1011的上端相连,右边梁1022的前端可以与右立柱1012的上端相连,后横梁1023连接左边梁1021的后部与右边梁1022的后部,即后横梁1023可以支撑在左边梁1021与右边梁1022之间以增加上部框架102整体的结构强度。
更加具体地,如图3所示,上部框架102还可以包括两个减震器安装板1024,减震器安装板1024可以安装车辆的减震器,减震器安装板1024可以分别位于左边梁1021与后横梁1023的连接处以及右边梁1022与后横梁1023的连接处,且两个减震器安装板1024可以分别位于左边梁1021和右边梁1022的相对内侧。
更加具体地,如图3所示,左边梁1021和右边梁1022之间的距离从前向后可以逐渐增大,即左边梁1021的弧形梁部分与右边梁1022的弧形梁部分从下向上逐渐相对背离,由此车辆的前方受到撞击时,撞击力能通过左边梁1021和右边梁1022分散后传递给驾驶舱,从而减少了车辆的受损程度。
更加具体地,如图3所示,上部框架102还包括左上加强杆1025和右上加强杆1026,左上加强杆1025的前端与左边梁1021相连且后端与后横梁1023相连,右上加强杆1026的前端与右边梁1022相连且后端与后横梁1023相连。左上加强杆1025可以增加左边梁1021与后横梁1023的连接强度,右上加强杆1026可以增加右边梁1022与后横梁1023的连接强度,由此上部框架102整体更加牢固。
更加具体地,如图3所示,位于上部框架102左侧的减震器安装板1024 可以安装在左上加强杆1025、左边梁1021以及后横梁1023形成的区域之内,位于上部框架102右侧的减震器安装板1024可以安装在右上加强杆1026、右边梁1022以及后横梁1023形成的区域之内。
在一些更加具体的实施例中,左边梁1021和右边梁1022中的每一个均可以包括前弧形段和后弧形段,由此,车辆的前方受到撞击时,弧形的左边梁1021与右边梁1022能在传递撞击力的过程中进行缓冲,从而减少车辆的受损程度。
在一些具体的实施例中,左边梁1021和右边梁1022中的前弧形段可以为内凹弧形段,后弧形段可以为外凸弧形段,内凹弧形段的圆心位于边梁的外侧,外凸弧形段的圆心位于边梁的内侧。
当然,左边梁1021与右边梁1022的形状可以不止于此,在另一些具体的实施例中,如图3所示,左边梁1021和右边梁1022中的前弧形段可以为外凸弧形段,后弧形段可以为内凹弧形段。
如图3所示,由于在左边梁1021与右边梁1022中,前弧形段与后弧形段的交界处的强度较低,左上加强杆1025的前端可以与左边梁1021的前弧形段和后弧形段的交界处相连,右上加强杆1026的前端可以与右边梁1022的前弧形段和后弧形段的交界处相连。由此可以增加了左边梁1021与右边梁1022在前弧形段与后弧形段的交界处的强度。
在一些具体的实施例中,如图4所示,下部框架103可以包括左纵梁1031、右纵梁1032和纵梁连接梁1034,左纵梁1031和右纵梁1032左右可以间隔开布置,左纵梁1031可以沿前后方向设置且构成下部框架103的左侧边,右纵梁1032可以沿前后方向设置且构成下部框架103的右侧边,左纵梁1031的后端与右纵梁1032的后端可以分别与车辆的驾驶舱框架连接。
如图3所示,左纵梁1031的前端可以与左立柱1011的下端相连,右纵梁1032的前端可以与右立柱1012的下端相连,纵梁连接梁1034连接左纵梁1031的前部与右纵梁1032的前部,即纵梁连接梁1034可以支撑在左纵梁1031与右纵梁1032之间以增加下部框架103整体的结构强度。
更加具体地,如图4所示,下部框架103还可以包括中间连接梁1033,中间连接梁1033可以沿前后方向延伸,且中间连接梁1033的前端可以与多个连接横梁中位于最下面的一个连接横梁(例如上述实施例中的下横梁1015)相连,中间连接梁1033的后端可以与车辆的驾驶舱框架相连,中间连接梁1033可以增加发动机舱框架100与驾驶舱框架的连接强度。
更加具体地,如图4所示,中间连接梁1033与纵梁连接梁1034互相垂直交叉形成十字形,即中间连接梁1033可以沿前后方向延伸,纵梁连接梁1034可以沿左右方向延伸,由此可以使下部框架103整体更加牢固。
在一些更加具体的实施例中,如图4所示,左纵梁1031的后部与右纵梁1032的后部均可以为直梁,左纵梁1031的直梁部分可以与右纵梁1032的直梁部分互相平行,左纵梁1031的前部与右纵梁1032的前部均可以为弧形梁,且左纵梁1031的弧形梁部分与右纵梁1032的弧形梁部分之间的距离从后向前可以逐渐增大,即左纵梁1031的弧形梁部分与右纵梁1032的弧形梁部分从后向前逐渐相对背离。
由此,当前部框架101受到撞击时,左纵梁1031和右纵梁1032可以进而分散受到的撞击力,减少发动机舱框架100的变形程度。
在一些可选的实施例中,发动机舱框架100可以为轻质合金框架,即前部框架101、上部框架102和下部框架103均可以为轻质合金框架,由此可以在车辆保持较强的刚度和防撞性能下减轻发动机舱框架100的重量,进而减轻了 整车重量。
进一步地,发动机舱框架100可以为铝合金框架,即前部框架101、上部框架102和下部框架103均可以为铝合金框架,从而前部框架101、上部框架102和下部框架103均可以经不同截面的铝合金型材挤压成型后,再通过焊接或铆接制成。由此发动机舱框架100造价便宜,成型简单,且具有良好的防腐性能。

本发明实施例的车辆设有如本发明上述任一种实施例的发动机舱框架100。
根据本发明实施例的车辆,通过设置发动机舱框架100,降低了整车的装配难度,提高了车辆的装配节拍。
