In the following embodiments, the terms "first" and "second" do not denote an absolute structural and/or functional distinction or a sequential order of execution, but are merely used for convenience of description.
As shown in fig. 1 to 4, the frame reinforcing structure of a new energy vehicle type comprises a reinforcing cross beam 2 arranged between two longitudinal beams 1 of a front cabin and connected with the two longitudinal beams 1, and bending parts 3 at two ends of the reinforcing cross beam 2 are respectively provided with a chassis control arm mounting bracket connecting hole 4. The chassis control arm mounting support connecting holes are arranged, so that the reinforcing cross beam is conveniently connected with the chassis control arm mounting support, the mounting part of the traditional chassis component is replaced, and the torsional rigidity and the bending rigidity of a white vehicle body are met.
As shown in fig. 1, the reinforcing beam 2 includes a middle straight beam and bending portions 3 symmetrically disposed at two ends of the middle straight beam, and the middle straight beam is provided with lightening holes 5. And the weight is reduced by arranging the lightening holes. Wherein, the preferred welded connection that adopts of middle straight beam and portion 3 of bending, firm strong reliability. When the device is arranged, the welding holes 6 are formed in the two ends of the bending part correspondingly connected with the middle straight beam, and welding is facilitated. The preferred a plurality of lightening holes, a plurality of lightening holes equipartition is in the length direction of middle straight beam. In order to achieve weight reduction and enable the reinforcing cross beam to have better mechanical properties, the weight reduction holes are distributed in the length direction of the middle straight beam in a mode of being arranged in a large-to-small interval mode. On the basis of meeting the use requirement of the reinforcing beam, in order to achieve the effect of further reducing weight, the reinforcing beam is preferably of a cavity structure.
On the effect of comprehensively considering weight reduction and lifting steering bending and torsional rigidity, the two reinforcing cross beams 2 are respectively a first reinforcing cross beam 7 and a second reinforcing cross beam 8, the bending parts at the two ends of the first reinforcing cross beam 7 are respectively provided with a first long circular sunk groove hole 9, a chassis control arm mounting support connecting hole is arranged in the first long circular sunk groove hole, the bending parts at the two ends of the second reinforcing cross beam 8 are respectively provided with a second long circular sunk groove hole 10, and a chassis control arm mounting support connecting hole is arranged in the second long circular sunk groove hole. The arrangement of the long circular sunk slot hole is convenient for being matched with and connected with a chassis control arm mounting bracket, a certain protection effect is formed on the joint, and the interference phenomenon at the joint is avoided.
The first reinforcing beam 7 and the second reinforcing beam 8 are arranged in parallel, the bending parts at the two ends of the second reinforcing beam 8 are respectively provided with two second long circular sunk slotted holes 10, and the two second long circular sunk slotted holes and the first long circular sunk slotted holes in the corresponding bending parts of the first reinforcing beam are distributed in a triangular mode. This kind of structure setting increases the steadiness after the erection joint, transversely reaches the vertical fine spacing effect that all plays of chassis control arm. The length of the first long circular sunk groove hole is designed to be relatively longer, and the length of the two second long circular sunk groove holes is designed to be relatively shorter and is oval.
