如图1-10所示，根据本本发明的实施例的汽车底盘防护装置100，包括：横梁10以及座体组件20。
具体而言，座体组件20可以包括横梁连接座21和车架连接座22，横梁连接座21与横梁10连接，横梁10可以是商用车的前下横梁，横梁连接座21包括倾斜地设在横梁10后侧的第一法兰板211。
车架连接座22包括第二法兰板221、左侧板222和右侧板223、连接板224以及承力件225。
第二法兰板221的前端面与第一法兰板211的后端面贴靠并与第一法兰211通过螺栓31连接。换言之，第一法兰211和第二法兰221相对贴合，在第一法兰211和第二法兰221上均设有法兰孔，螺栓31穿过法兰孔并将第一法兰211和第二法兰221固定，以将横梁连接座21和车架连接座22固定。
左侧板222和右侧板223间隔设置在第二法兰221的后端面上，左侧板222和右侧板 223与第二法兰221的后端面垂直，左侧板222和右侧板223上分别设有相对的安装孔32，通过穿过安装孔32的安装螺栓(未示出)，可以将左侧板222和右侧板223固定在车架连接板300上。左侧板222和右侧板223可以起到将汽车底盘防护装置100与车架连接板300有效连接的作用，同时，能够承受部分从侧面受到的外力。
连接板224的左端可以与左侧板222连接，连接板224的右端可以与右侧板223连接，连接板224邻近左侧板222和右侧板223的前端设置，连接板224可以与车架连接板300的前端相抵，以将外力的分力有效地传递到车架连接板300上。

如图5-7所示，根据本发明的一个实施例，第二法兰板221的前端面上凸出有定位销40，第一法兰板211的后端面上设有与定位销40匹配的凹部(未示出)。设置定位销40可以方便第二法兰板221和第一法兰板211的定位和安装，同时，定位销40也起到了抗剪切的作用，使第一法兰板211和第二法兰板221连接的更加牢固，在收到撞击时，不易发生相对位移。
如图5、图7所示，根据本发明的一个实施例，连接板224可以包括：本体部2241、左折边2242以及右折边2243，左折边2242向后弯折并与左侧板222连接，右折边2243向后弯折并与右侧板223连接，例如左折边2242与左侧板222焊接，右折边2243与右侧板223焊接。由此，在车架连接座22受力时，可以有效地将外力通过连接板224传递到车架连接板300上。
如图5、图7所示，根据本发明的一个实施例，承力件225的横截面可以为U形，承力件225的开口端与第二法兰板221的后端面连接。由此，在承力件225起到上下承力的作用的同时，可以减少承力件225制造时的用料，节约生产成本。
如图4所示，根据本发明的一个实施例，横梁连接座21可以进一步包括左立板212、右立板213以及加强槽板214。左立板212和右立板213间隔设置在第一法兰板211的前端面上，左立板212和右立板213与第一法兰板211的前端面垂直。加强槽板214的后端 与左立板212和右立板213连接，加强槽板211的前端设有用于安装横梁10的安装槽215。横梁10可以被焊接在安装槽215内。由此，可以提高横梁10的受力承载能力。
如图4所示，根据本发明的一个实施例，座体组件20可以为多个。由此，可以更有利于横梁10收到了力传导至座体组件20和车架连接板300上。
如图4所示，根据本发明的一个实施例，左立板212和右立板213的上端分别设有与第二法兰板221上端匹配的挂钩50。在装配时，将横梁连接座21通过挂钩50挂在第二法兰板221上端，然后在用螺栓31将第一法兰211和第二法兰221进行锁紧即可，装配更加方便。进一步地，根据本发明的一个实施例，左立板212和右立板213上均设有至少两个挂钩50。
如图8所示，根据本发明的一个实施例，横梁10可以包括：第一槽钢11、第二槽钢12以及第三槽钢13。
具体而言，第一槽钢11的开口和第二槽钢11的开口相对焊接。第三槽钢13的开口端与第一槽钢11的内底壁焊接，第三槽钢13的外底壁与第二槽钢12的内底壁焊接。由此，可以形成一个完整的高强度的矩形钢管。进一步地，第三槽钢13的开口由底部向上逐渐变大。在制作横梁10时，可以首先将第三槽钢12的外底壁与第二槽钢12焊接，然后再将第一槽钢11和第二槽钢12开口相对焊接，最后再将第一槽钢11与第三槽钢13的开口端焊接，例如，可以通过塞焊的方式将一槽钢11与第三槽钢13的开口端焊接。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。此外，本领域的技术人员可以将本说明书中描述的不同实施例或示例进行接合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
