The invention relates to the technical field of automobiles, and discloses a convenient-to-disassemble sealing structure for a power battery and a vehicle body frame and a vehicle, sealing strips made of EPDM (Ethylene-Propylene-Diene Monomer) closed-cell foam materials are circumferentially arranged between an upper cover of the power battery and a doorsill beam and on a bolt connecting surface of the power battery, and the sealing problem of the power battery and the vehicle body frame is solved; the arrangement width of the two EPDM closed-cell foam sealing strips is widened, so that the sound insulation index of the gap between the power battery and the vehicle body frame can be improved, and the noise in the vehicle is reduced; the sealing strip made of the EPDM closed-cell foam material is adopted to replace sealant for sealing and sound insulation, when a certain part of the power battery goes wrong and needs to be replaced or maintained, the whole chassis of the vehicle does not need to be disassembled, the power battery can be easily removed by disassembling the bolts, it is guaranteed that after the power battery is disassembled, a battery pack does not deform, offset printing is not left, and the service life of the power battery is prolonged. The convenience of dismounting and mounting is improved, and the maintenance cost is reduced.
本发明涉及汽车技术领域,公开了一种便于拆卸的动力电池与车身框架的密封结构及车辆,在动力电池上盖与门槛梁之间以及动力电池螺栓连接面布置周圈的EPDM闭孔泡棉材质的密封条,解决动力电池与车身框架的密封问题;两道EPDM闭孔泡棉密封条的布置宽度加宽,可以提高动力电池与车身框架间隙的隔声量,降低车内噪声;采用EPDM闭孔泡棉材质的密封条代替密封胶进行密封和隔声,当动力电池某部件出现问题,需要更换或维修零部件时,无需拆卸车辆的整个底盘,通过拆除螺栓,即可轻松移除动力电池,保证动力电池拆卸后电池包不变形,且不留胶印,提高拆卸与安装的便利性,降低维修成本低。
