The battery pack frame comprises a frame assembly and a battery pack assembly arranged on the inner side of the frame assembly, and the frame assembly comprises two longitudinal beams arranged in parallel and a cross beam set used for connecting the two longitudinal beams. The cross beam group comprises a plurality of first cross beams arranged between the two longitudinal beams, at least one second cross beam arranged on one side of the two longitudinal beams and a sealing plate group arranged on the longitudinal beams close to the middle part, and the sealing plate group comprises a front sealing plate and a rear sealing plate arranged on one side far away from the front sealing plate; the sealing plate group and the two longitudinal beams are enclosed to form a battery cabin for accommodating a battery pack assembly, an operator can put the battery pack assembly along the bottom of the battery cabin, and the surrounding edge of the battery pack assembly is respectively connected with the frame assembly through bolts; the problem that a battery pack box body and a battery pack support which are connected with the frame need to be additionally installed when an existing battery pack is installed is avoided, the weight of the battery pack frame is reduced, the weight is reduced, and meanwhile the cost of the battery pack frame is further reduced.
本发明提供一种电池包车架及汽车,包括车架总成以及设置在车架总成内侧的电池包总成,车架总成包括两平行设置的纵梁以及用于连接两纵梁的横梁组,横梁组包括设置在两纵梁之间的多根第一横梁、设置在两纵梁一侧的至少一第二横梁以及纵梁上靠近中间部位设置的封板组,封板组包括前封板以及远离前封板一侧设置的后封板,封板组和两纵梁围合形成用于容置电池包总成的电池舱,操作人员可将电池包总成沿电池舱底部放入,并通过螺栓分别将电池包总成围边处和车架总成进行连接,免去了现有电池包在安装时需要加装与车架连接的电池包箱体及电池包支架,减轻电池包车架本身重量达到轻量化的同时进一步降低电池包车架成本。
