The invention provides a double-electric-drive-axle driving structure and a vehicle. The double-electric-drive-axle driving structure comprises a middle-axle electric drive axle, a rear-axle electric drive axle, a first driving part, a second driving part and a controller. The middle-axle electric drive axle and the rear-axle electric drive axle are coaxially arranged, the first drive part is in drive connection with the middle-axle electric drive axle, and the second drive part is in drive connection with the rear-axle electric drive axle; wherein the middle-axle electric drive axle is a single-speed electric drive axle, the rear-axle electric drive axle is a multi-gear electric drive axle, and the controller is electrically connected with the first drive assembly and the second drive assembly and used for controlling actions of the multi-gear electric drive axle and the single-speed electric drive axle respectively. The middle axle and the rear axle are controlled through the controller of the double-electric-drive-axle driving structure, so that inter-axle electronic differential exists between the middle axle and the rear axle, and it is guaranteed that the whole vehicle runs in a stable state.

本发明提供一种双电驱桥驱动结构及车辆，上述的双电驱桥驱动结构包括中桥电驱桥、后桥电驱桥、第一驱动件、第二驱动件及控制器；中桥电驱桥和后桥电驱桥同轴设置，第一驱动件与中桥电驱桥驱动连接，第二驱动件与后桥电驱桥驱动连接；其中中桥电驱桥为单速电驱桥，后桥电驱桥为多挡电驱桥，控制器与第一驱动组件和第二驱动组件电性连接，用于分别控制多挡电驱桥和单速电驱桥的动作。该通过双电驱桥驱动结构控制器控制中桥和后桥，能够使得中桥和后桥之间存在轴间电子差速，保证整车以稳定状态行驶。
