The frame comprises a front beam, a middle body and a rear beam, the middle body comprises a frame body and a reinforcing part, the frame body is provided with an inner cavity, the reinforcing part is arranged in the inner cavity and divides the inner cavity into at least two containing cavities, the containing cavities are used for installing battery cells, the frame body is provided with a front end and a rear end, and the front beam and the rear beam are connected to the front end and the rear end respectively. And the front beam, the rear beam and the middle body are integrally formed. According to the frame, the reinforcing piece is arranged in the inner cavity of the frame body, and the front beam, the rear beam and the frame body are integrally formed, so that the problem that a traditional steel pipe frame needs to be punched, bent, welded and other complex machining processes can be solved, the production efficiency can be improved, the production difficulty can be reduced, and it can be guaranteed that the frame has enough structural strength. Besides, the inner cavity of the frame body is divided into at least two accommodating cavities by the reinforcing pieces for mounting the battery cells, so that the middle body can be used as a carrier for mounting the battery cells, reliable mounting of the battery cells is ensured, and the structural layout of the frame is optimized.
本申请涉及一种车架,包括前梁、中间体及后梁,中间体包括框体与加固件,框体具有内腔,加固件设于内腔,且加固件将内腔分割为至少2个容置腔,容置腔用于安装电芯,框体具有前端与后端,前梁与后梁分别连接于前端与后端,且前梁、后梁与中间体一体成型。上述车架,加固件设于框体的内腔,且前梁、后梁与框体一体成型,如此能够避免传统钢管车架存在的需冲裁、折弯及焊接等复杂的加工工艺问题,有利于提高生产效率及降低生产难度,并能够保证车架具有足够的结构强度。另外,加固件将框体的内腔分割为至少2个容置腔,以用于安装电芯,如此设置使得中间体能够作为安装电芯的载体,保证了电芯的可靠安装,并且优化了车架的结构布局。
