Electric vehicle beam structure

Abstract

The invention discloses a beam frame structure of an electric vehicle. The beam frame structure comprises a base frame, a front support, a rear support, four suspension parts and four wheels, wherein the base frame is in a four-corner framework structure surrounding by four frame edges; the front support comprises two front support arc pipes and a front support connecting pipe; the rear support comprises two rear support arc pipes and a rear support connecting pipe; one ends of the two suspension parts are assembled on a front assembling platform of the front support, and the other ends of the two suspension parts are respectively connected with the two wheels, one ends of the other two suspension parts are assembled on the rear support connecting pipe of the rear support, and the other ends of the other two suspension parts are respectively connected with the other two wheels. The front support and the rear support are connected with the suspension parts by the arc pipes, and through the arc pipes in the bent arc shapes, the structure is simplified, the stressed area is increased, and the bearing capability can be improved. The arc pipes in the bent arc shapes can reduce joints of sharp corners, the structure weakness of the focused stress can be avoided, the integral structure strength of a beam frame can be enhanced, and the safety is improved.

Description

technical field [0001] The invention relates to a beam frame structure of a vehicle, in particular to a beam frame structure of an electric vehicle. Background technique [0002] The vehicle is one of the indispensable means of transportation in daily life. The vehicle has a basic beam frame, and other accessories of the vehicle are assembled on the beam frame. The beam frame affects the convenience of assembling other accessories, and the beam frame also bears the load of the vehicle. , the basic structure of the vehicle is the beam frame, and the structural strength of the beam frame is related to the safety of the vehicle. [0003] like figure 1 As shown, a vehicle frame X is formed by connecting a plurality of frame tubes X1, and the joint angle between the frame tubes X1 is a right angle or an oblique angle formed by straight frame tubes X1. The angle between them is a sharp angle. The frame X bears all the loads. The structural rigidity of the frame X directly affect...

Problems solved by technology

[0003] like figure 1 As shown, a vehicle frame X is formed by connecting a plurality of frame tubes X1. The joint angle between the frame tubes X1 is a right angle or an oblique angle formed by straight frame tubes X1. The angle between them is a sharp angle. The frame X bears all the loads. The structural rigidity of the frame X directly affects the safety of the vehicle. The structural weakness of the frame X lies in the connection between the frame tubes X1. When the frame X When the frame tubes X1 are at sharp or right angles, stress concentration will occur at the connection between the frame tubes X1. When the frame X bears too much weight or undergoes a collision, it is easy to cause structural damage, resulting in potential safety hazards for the vehicle.
