技术领域
本公开属于汽车电池包安装技术领域，涉及一种车身框架及汽车，特别是涉及一种车身框架及具有该车身框架的汽车。
背景技术
电动汽车作为新能源汽车的代表，因其清洁、经济性受到越来越多的关注。但是由于电池容量和充电时间的原因，限制了电动汽车的发展。近些年兴起的电动汽车换电站结合自动快换设备理念，使得电动汽车的发展迎来了曙光。电动车换电理念即在电动汽车电池要用完电时，进入换电站电池箱卸下，换上满电电池箱。整个换电过程在换电站的自动换电设备作用下完成，只需要3分钟，即在普通内燃机车进入加油站一次的时间内，即可完成电池更换，这样大大减少了电动汽车用户的充电及电池保养的麻烦，同时加大了电动汽车的续航里程。
但是现有技术中的车身框架存在无法针对不同尺寸电池包进行安装的问题，且在遭遇碰撞时，无法更好地保护车形。
因此，如何提供一种车身框架及具有该车身框架的汽车，以解决现有技术中的车身框架无法针对不同尺寸电池包进行安装的问题，且在遭遇碰撞时，无法更好地保护车形等缺陷，实已成为本领域技术人员亟待解决的技术问题。

于本公开的一实施例中，所述拆卸式电池包安装梁的一端插接于一连接件内；所述连接件设于所述车身框架的侧门槛梁和前纵梁之间。
于本公开的一实施例中，所述侧门槛梁、所述连接件及所述前纵梁形成车身正面碰撞的传递路径。
于本公开的一实施例中，所述拆卸式电池包安装梁与所述侧门槛梁之间连接有横向支撑。
于本公开的一实施例中，所述侧门槛梁、所述横向支撑及所述拆卸式电池包安装梁形成车身侧面碰撞的传递路径。
于本公开的一实施例中，所述固定件的形状与所述侧门槛梁的内凹槽的形状相匹配。
于本公开的一实施例中，在所述车身框架包括第二类型电池包时，所述车身框架还包括吸能件；所述吸能件插入所述侧门槛梁的内腔体，形成车身侧面碰撞的传递路径。
本发明另一方面提供一种汽车，包括所述的车身框架。
如上所述，本公开的车身框架及具有该车身框架的汽车，具有以下有益效果：
本公开所述的车身框架及具有该车身框架的汽车实现两种类型的电池包在铝车身框架上的安装，增加的电池包安装点可有效的参与碰撞路径，提升车身碰撞安全性。
