【detailed description】

In order to make the purpose, technical solution and beneficial technical effects of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementations described in this specification are only for explaining the utility model, not for limiting the utility model.

Please refer to Fig. 1 to Fig. 2 together, a new vehicle frame structure of the present utility model specifically includes a longitudinal beam 10 and a crossbeam 20 perpendicular to the longitudinal beam 10, and the longitudinal beam 10 adopts a hollow aluminum profile Made, the hollow aluminum profile is provided with reinforcing ribs 30, and the beam 20 is in the shape of a strip.

The longitudinal beam 10 of the vehicle frame in the utility model adopts a hollow aluminum profile structure, which helps to reduce the self-weight of the vehicle frame, and the longitudinal beam is built with reinforcing ribs, which helps to improve the strength of the longitudinal beam. The frame structure solves the defect that the steel frame in the traditional technology has a large frame weight, which cannot be realized and the effect of lightweighting the car.

Specifically, as shown in Figures 3 to 5, the cross-sectional area of the longitudinal beam 10 is a rectangle, including a first wall 11, a second wall 12, a third wall 13 and a fourth wall 14, the first wall 11 and the fourth wall 14. The third wall 13 is arranged in parallel, the second wall 12 and the fourth wall 14 are arranged in parallel and perpendicular to the first wall 11 and the third wall 13, the first wall 11, the second wall 12, the third wall The wall 13 and the fourth wall 14 form the longitudinal beam 10 whose cross-sectional area is rectangular, and the reinforcing rib 30 is connected between the second wall 12 and the fourth wall 14, and is connected with the first wall 11 parallel settings.
