如图2和图3所示，驾驶舱下部框架202可以固定在顶盖框架总成201的下方，前围板203可以固定在驾驶舱下部框架202的前部，前围板203可以遮住驾驶舱下部框架202的前部，地板面板可以固定在驾驶舱下部框架202的底部，地板面板可以遮住驾驶舱下部框架202的底部，后围板204可以遮住驾驶舱下部框架202的后部。
由此，驾驶舱框架200可以包括左侧围上边梁2011、右侧围上边梁2012、顶盖前横梁2013、顶盖后横梁2014、驾驶舱下部框架202、前围板203、地板面板和后围板204八个模块，人员在装配驾驶舱框架200前，可以预先将不同截面的型材通过焊接或铆接制成左侧围上边梁2011、右侧围上边梁2012、顶盖前横梁2013、顶盖后横梁2014、驾驶舱下部框架202、前围板203、地板面板和后围板204。
人员在装配驾驶舱框架200时，可以直接将左侧围上边梁2011、右侧围上边梁2012、顶盖前横梁2013、顶盖后横梁2014、驾驶舱下部框架202、前围板203、地板面板和后围板204焊接或铆接在一起，进而完成驾驶舱框架200的装配。相对于传统的驾驶舱框架，减少了驾驶舱框架200装配时所需的零件数量，节约了驾驶舱框架200的装配时间，驾驶舱框架200的装配更容易。
进一步地，人员在装配车身框架总成1000时，可以直接将发动机舱框架100、驾驶舱框架200和行李舱框架300焊接或铆接在一起，进而完成车身框架总成1000的装配。相对于传统的车身框架总成，减少了车身框架总成1000装配时所需的零件数量，节约了车身框架总成1000的装配时间，车身框架总成1000的装配更容易。
根据本发明实施例的车身框架总成1000，通过设置左侧围上边梁2011、右侧围上边梁2012、顶盖前横梁2013、顶盖后横梁2014、驾驶舱下部框架202、 前围板203、地板面板和后围板204，使驾驶舱结构模块化，减少了驾驶舱框架200装配时所需的零件数量，节约了驾驶舱框架200的装配时间，降低驾驶舱框架200的开发成本，驾驶舱框架200的装配更容易。
同时，车身框架总成1000通过设置发动机舱框架100、驾驶舱框架200和行李舱框架300，使车身结构模块化，减少了车身框架总成1000装配时所需的零件数量，节约了车身框架总成1000的装配时间，降低车身框架总成1000的开发成本，车身框架总成1000的装配更容易。
优选地，如图4所示，驾驶舱下部框架202可以包括左右间隔设置的两个A柱2021、左右间隔设置的两个B柱2022、驾驶舱左下边梁2023、驾驶舱右下边梁2024、驾驶舱前横梁2025、驾驶舱后横梁2027和驾驶舱中间横梁2026，驾驶舱下部框架202可以由两个A柱2021、两个B柱2022、驾驶舱左下边梁2023、驾驶舱右下边梁2024、驾驶舱前横梁2025、驾驶舱后横梁2027和驾驶舱中间横梁2026彼此拼焊或铆接制成。
如图4所示，左侧的B柱2022可以位于左侧A柱2021的后方，右侧的B柱2022可以位于右侧A柱2021的后方，驾驶舱左下边梁2023可以分别与左侧的A柱2021的下端与左侧的B柱2022的下端连接，驾驶舱右下边梁2024可以分别与右侧的A柱2021的下端与右侧的B柱2022的下端连接。

可以理解的是，驾驶舱下部框架202的前端可以由两个A柱2021和驾驶舱前横梁2025构成，驾驶舱下部框架202的后端可以由两个B柱2022和驾驶 舱后横梁2027构成，驾驶舱中间横梁2026可以位于驾驶舱前横梁2025和驾驶舱后横梁2027之间，驾驶舱中间横梁2026可以使驾驶舱下部框架202整体结构更加牢固。
在一些更加具体的实施例中，如图4所示，驾驶舱下部框架202还可以包括驾驶舱连接纵梁2028，驾驶舱连接纵梁2028可以沿前后方向延伸，且驾驶舱连接纵梁2028可以连接在驾驶舱前横梁2025和驾驶舱中间横梁2026之间。
如图4所示，在左右方向上，驾驶舱连接纵梁2028可以位于驾驶舱左下边梁2023和驾驶舱右下边梁2024之间，驾驶舱连接纵梁2028可以与驾驶舱前横梁2025以及驾驶舱后横梁2027互相平行，由此驾驶舱连接纵梁2028可以进一步增强驾驶舱下部框架202整体的结构强度。
在一些更加具体的实施例中，如图4所示，驾驶舱下部框架202还可以包括两个辅助连接纵梁20281，两个辅助连接纵梁20281可以沿前后方向延伸，且两个辅助连接纵梁20281可以连接在驾驶舱前横梁2025和驾驶舱中间横梁2026之间。
如图4所示，在左右方向上，两个辅助连接纵梁20281可以位于驾驶舱左下边梁2023和驾驶舱右下边梁2024之间，两个辅助连接纵梁20281可以分别位于驾驶舱连接纵梁2028的左右两侧，两个辅助连接纵梁20281可以与驾驶舱前横梁2025以及驾驶舱后横梁2027互相平行，由此可以进一步增强驾驶舱下部框架202整体的结构强度。
在一些更加具体的实施例中，如图3所示，地板面板可以包括左前地板2052、右前地板2051和后地板2053，左前地板2052可以安装在驾驶舱下部框架202的底部的左前部，右前地板2051可以安装在驾驶舱下部框架202的底部的右前部，后地板2053可以安装在驾驶舱下部框架202的底部的后部。
更加具体地，如图3所示，左前地板2052可以安装在驾驶舱连接纵梁2028、驾驶舱前横梁2025、驾驶舱左下边梁2023和驾驶舱中间横梁2026限制的区域内，右前地板2051可以安装在驾驶舱连接纵梁2028、驾驶舱前横梁2025、驾驶舱右下边梁2024和驾驶舱中间横梁2026限制的区域内，后地板2053可以安装在驾驶舱右下边梁2024、驾驶舱后横梁2027、驾驶舱左下边梁2023和驾驶舱中间横梁2026限制的区域内。
需要说明的是，位于左侧的辅助连接纵梁20281可以设在左前地板2052的下方，位于右侧的辅助连接纵梁20281可以设在右前地板2051的下方，地板面板可以避让驾驶舱连接纵梁2028和驾驶舱中间横梁2026，方便地板面板安装在驾驶舱下部框架202的底部。
具体地，如图4所示，驾驶舱左下边梁2023和驾驶舱右下边梁2024的上表面还可以分别设有门槛安装板2029，门槛安装板2029可以为车辆的车门提供安装点。
在一些具体的实施例中，如图5所示，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。
在一些具体的实施例中，如图6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5所示，左边梁1021的前端可以与前部框架101的右上端相连，左边梁1021的后端可以与左边的A柱2021的底部相连，右边梁1022的前端可以与前部框架101的左上端相连，右边梁1022的后端可以与右边的A柱2021的底部相连，后横梁1023可以连接左边梁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6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5和图6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6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的前端可以与左边梁1021相连且后端可以与后横梁1023相连，右上加强杆1026的前端可以与右边梁1022相连且后端可以与后横梁1023相连。由此，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6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，进而减小传向A柱2021的碰撞力，由此减小了驾驶舱框架200受到的冲击，保障了车内人员的安全。
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6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6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。
在一些优选的实施例中，如图7所示，发动机舱框架100的前端可以设有前防撞梁104，前防撞梁104可以包括前防撞梁本体1041，前防撞梁本体1041的后方可以沿左右方向间隔设有两个前防撞梁连接部1042，前防撞梁104可以通过前防撞梁连接部1042与前部框架101螺纹连接。
如图8和图9所示，前防撞梁104可以为空心梁，可以理解的是，前防撞梁本体1041与两个前防撞梁连接部1042均可以为空心梁，由此可以减轻车辆整体的重量，从而减小了车辆在碰撞时产生的冲击力，且车辆在碰撞时前防撞梁104更易变形以吸收能量，进而保护驾驶舱的完整性，保障车内人员的安全。
具体地，如图8所示，前防撞梁本体1041内可以设有加强肋板10411以增加前防撞梁本体1041的刚度，加强肋板10411可以为多个，每个加强肋板10411可以沿左右方向延伸，且每个加强肋板10411可以连接前防撞梁本体1041内壁的上表面和下表面。
在一些可选的实施例中，车身框架总成1000均可以为轻质合金框架，即发动机舱框架100、驾驶舱框架200和行李舱框架300均可以为轻质合金件，由此可以在车辆保持较强的刚度和防撞性能下减轻车身框架总成1000的重量，进而减轻了整车重量。
在一些具体的实施例中，车身框架总成1000可以为铝合金框架，即发动机舱框架100、驾驶舱框架200和行李舱框架300均可以为铝合金件，从而发 动机舱框架100、驾驶舱框架200和行李舱框架300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。由此车身框架总成1000造价便宜，成型简单，且具有良好的防腐性能。
下面描述本发明实施例的车辆。
本发明实施例的车辆设有如本发明上述任一种实施例的车身框架总成1000。
根据本发明实施例的车辆，通过设置车身框架总成1000，降低了整车的装配难度，提高了车辆的装配节拍。
