Embodiment Construction

[0019] Such as Figure 1 to Figure 4 As shown, an electric vehicle front cabin element fixing structure includes left and right longitudinal beam assemblies arranged on both sides of the front cabin, namely, a first front longitudinal beam assembly 1 and a second front longitudinal beam assembly 2; Between the first front longitudinal beam assembly 1 and the second front longitudinal beam assembly 2, there are a front cabin front inner cross member assembly 3 and a front cabin rear inner cross member assembly 4 for fixing elements in the front cabin. The cross beam assembly 3 and the front rear inner cross beam assembly 4 are arranged side by side. The connection between the left and right side beam assemblies is strengthened, and the rigidity of the vehicle, especially the front cabin, is improved.

[0020] In order to facilitate installation and maintenance, both ends of the front inner cross beam assembly of the front cabin and the rear inner cross beam assembly of the front ...

Abstract

The invention discloses a front cabin element fixing structure for an electric vehicle. The front cabin element fixing structure for the electric vehicle comprises a left longitudinal beam assembly and a right longitudinal beam assembly arranged on the two sides of a front cabin; and a front-cabin front inner beam assembly and a front-cabin back inner beam assembly which are used for fixing elements in the front cabin are arranged between the left longitudinal beam assembly and the right longitudinal beam assembly. Therefore, the connectivity of the left longitudinal beam assembly and the right longitudinal beam assembly is enhanced and the rigidity of an overall vehicle, particularly the front cabin, is improved. The two beams are made into a cavity structure by adopting two layers of plates, so that the strength and the rigidity of an overall beam are effectively improved, the risk of bending the beam is reduced, and the Z-directional precision of an installation point can be ensured. A plurality of connecting pieces are reduced, so that the weight and the cost of the overall vehicle are reduced favorably, and further the performance and the competitive power of the overall vehicle are further increased.

Description

Technical field [0001] The present invention relates to the technical field of electric vehicles, in particular to a fixing structure for front cabin elements of electric vehicles. Background technique [0002] As an important means of transportation, automobiles are becoming more and more popular. At the same time, the safety performance of automobiles is getting more and more attention with the popularity of automobiles. Good rigidity of the car body is an important factor. [0003] The main difference between an electric car and an ordinary car is that it does not have an engine but uses a generator, and a controller, converter, battery, and charger are added accordingly. Most of these added components are arranged in the front compartment of electric vehicles. Due to their volume and weight limitations, their fixation can no longer be realized by using the fixation structure of ordinary cars in the past. [0004] The brackets used for fixing the front compartment elements of t...
