Problems solved by technology
The structure of the beam is single, which cannot well disperse the stress during the impact. For high-performance cars and sports cars, the car body will deform greatly during intense movement, which will affect the maneuverability and safety of the whole vehicle
At the same time, the weight of the steel body structure has no advantage

Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing:
[0021] Such as figure 1 , figure 2 and image 3 As shown, a kind of automobile frame, including the front frame (mainly including figure 1 6 and 7) and the rear girder, the front girder and the rear girder are composed of longitudinal beams and beams, the front girder is fixedly connected to the rear girder through a figure-eight / herringbone structure 1, the eight The front narrow end of the glyph / herringbone structure 1 is fixedly connected to the front girder, and the two rear ends of the figure-eight / herringbone structure 1 are fixedly connected to the longitudinal girder of the rear girder. The main reason for setting the figure-eight / herringbone structure 1 in this way is that the front frame corresponds to the front wheel part of the car, which is wider than the rear frame, so a figure-eight / herringbone structure 1 of equal length is used to ensure that the front ...

The invention discloses an automobile beam. The automobile beam comprises a front beam and a back beam, wherein each of the front beam and the back beam consists of a longitudinal beam and a cross beam; the front beam is fixedly connected with the back beam through a splayed / herringbone structure; the front narrow end of the splayed / herringbone structure is fixedly connected with the front beam; two end parts of the back part of the splayed / herringbone structure are fixedly connected with the longitudinal beam of the back beam; two ends of the tail of the back beam are folded inwards to form a trapezoidal structure; in two bottoms of the trapezoidal structure, the first bottom is longer than the second bottom; two reinforcing beams are fixedly connected between two intersection points of the second bottom and the waist of the trapezoidal shape, and the first bottom of the trapezoidal structure; and one reinforcing beam, the waist, positioned on the reinforcing beam side, of the trapezoidal structure and the first bottom of the trapezoidal structure form a triangular structure.
Description
technical field [0001] The invention relates to an automobile frame. Background technique [0002] For traditional cars, in order to achieve low-cost and large-scale production, a load-bearing body structure is usually used, that is, high-strength steel stamping parts are used as stress-bearing parts of the body frame. The structure of the girder is single, which cannot well disperse the stress during impact. For high-performance cars and sports cars, the car body will undergo large deformation during intense movement, which will affect the maneuverability and safety of the vehicle. At the same time, the steel body structure has no weight advantage. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an automobile frame capable of dispersing stress. [0004] The technical scheme provided by the invention is: [0005] An automobile girder, comprising a front girder and a rear girder, the front girder and the r...
