Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
Referring to fig. 1, 3 and 5, the present invention provides a vehicle battery pack mounting frame including a front floor 1, a rocker beam front section 2 extending in a vehicle front-rear direction, and a front floor lower beam section 3 extending in a vehicle width direction, wherein the front floor lower beam section 3 is disposed at a front end of a bottom surface of an outermost side of the front floor 1 in the vehicle front-rear direction, the rocker beam front section 2 is disposed at a side of the front floor 1 in the vehicle width direction, and the front floor lower beam section 3 and the rocker beam front section 2 are fixedly connected; the outermost bottom surface of the front floor lower cross-member section 3 and the outermost bottom surface of the rocker front section 2 are arranged flush with each other and are spaced from the outermost bottom surface of the front floor 1 in the height direction of the vehicle, so that a battery housing receiving groove 4 is formed between the outermost bottom surface of the front floor 1, the front floor lower cross-member section 3, and the rocker front section 2.
Since the front floor lower cross member section 3 is provided at the front end of the bottom surface of the front floor 1 in the front-rear direction of the vehicle, the rocker front section 2 is provided at the side of the front floor 1 in the width direction of the vehicle, and the front floor lower cross member section 3 and the rocker front section 2 are fixedly connected, while the bottom surface of the front floor lower cross member section 3 and the bottom surface of the rocker front section 2 are arranged flush with each other and are spaced apart from the bottom surface of the front floor 1 in the height direction of the vehicle, which allows the battery accommodating groove 4 to be formed between the bottom surface of the front floor 1, the front floor lower cross member section 3 and the rocker front section 2, and the battery pack 15 mounted on the bottom surface of the front floor 1 can be accommodated in the battery accommodating groove 4, so that the front floor lower cross member section 3 and the rocker front section 2 can protect the entire height of the edge of the battery pack 15, and thus, when the vehicle is involved in a front collision or side collision, the front floor lower cross member 3 and the rocker front section 2 can provide better protection to the edge of the battery pack, the risk that the battery pack is further extruded can be reduced, so that the anti-collision safety of the battery pack is improved, and the safety performance of the vehicle is effectively improved.
It is important to note here that the "flush arrangement" does not mean that the outermost bottom surface of the front floor lower cross member section 3 and the outermost bottom surface of the rocker beam front section 2 must be flush, and in practice, due to manufacturing and assembly tolerances, there may be some height differences in the vehicle height between the outermost bottom surface of the front floor lower cross member section 3 and the outermost bottom surface of the rocker beam front section 2, as long as they do not affect the overall height of the edge of the battery pack 15. Therefore, in the vehicle battery pack mounting frame as claimed in the present application, the "flush arrangement" allows a small height difference in the Z direction between the outermost bottom surface of the front floor lower cross-member section 3 and the outermost bottom surface of the rocker beam front section 2.
Of course, with "substantially flush arrangement", due to manufacturing and assembly tolerances, a small height difference in the Z direction is also allowed between the outermost bottom surface of the front floor lower beam section 3 and the outermost bottom surface of the rocker front section 2.
