Detailed Description
The following will be described in detail with reference to the specific embodiments of the present invention to help those skilled in the art to understand the concept and technical solution of the present invention more completely, accurately and deeply.
Example 1
The embodiment provides a power battery rear mounting structure, and the design concept of this embodiment is that a power battery mounting crossbeam is designed at the mounting position behind the next-door neighbour power battery, and the cross-sectional dimension of crossbeam requires to be as little as possible, does not occupy the space beyond the power battery, and both ends design the support, through the bolt install on the longeron of both sides, whole height dimension will be less than the height of old structure, design the mounting hole on the crossbeam for install the power battery. The power battery rear mounting beam assembly and the power battery are mounted together on a general assembly line. The rear floor center cross member and then the suspension mounting hard point position are arbitrarily arranged in the X direction without being restricted by the battery rear mounting point. As shown in fig. 3, the rear power battery mounting structure of the present embodiment includes a rear power battery mounting cross member assembly 30 disposed between the rear floor side member assemblies 10 on both sides, where the rear power battery mounting cross member assembly 30 is located on the lower surface of the rear floor side member assembly 10 (fig. 3 is an axial view), and the rear power battery mounting cross member assembly 30 is located in front of the rear floor middle cross member 20 along the vehicle rear direction (arrow direction in the figure). As shown in fig. 4, the power battery rear mounting beam assembly 30 includes a mounting support 50 and a rear mounting beam 60 disposed on the mounting support 50, the rear mounting beam 60 is provided with a through hole, and a press-riveting threaded sleeve 61 is disposed in the through hole, as shown in fig. 3 and 5, the rear end of the power battery 40 is fixedly connected to the rear mounting beam 60 through a mounting bolt 70 penetrating through the press-riveting threaded sleeve 61, the rear mounting beam 60 is made of an aluminum alloy material (adopting an equal-section aluminum alloy extrusion process), and is a hollow structure with a rectangular outer contour, and a vertical reinforcing beam is disposed in the hollow structure. As shown in fig. 6, the mounting bracket 50 includes a bottom plate 51 engaged with the lower surface of the rear floor side rail assembly 10, a support seat 52 provided on the bottom plate 51, and a mounting sleeve 53 provided on the support seat 52, an end portion of the rear mounting cross member 60 is inserted into the mounting sleeve 53 and fixed by welding, and the bottom plate 51 is fixed to the lower surface of the rear floor side rail assembly 10 by a mounting bolt 70.
