Spatial truss type steel tube frame with solid structure

Abstract

The invention discloses a spatial truss type steel tube frame with a solid structure. The spatial truss type steel tube frame with the solid structure comprises front anti-collision beams, top frames,a chassis underframe and a motor steel frame; front anti-collision beam supporting rods are welded between the front anti-collision beams in a crossed manner; ceiling supporting rods are welded between the top frames in a crossed manner; front windshield steel tubes are movably hinged between the front anti-collision beams and the top frames; rear windshield steel tubes are movably hinged betweenthe top frames and the motor steel frame; the middle ends of the front windshield steel tubes are welded on the chassis underframe through front vertical rods; the front and rear ends of the rear windshield steel tubes are respectively welded on the chassis underframe through double longitudinal beams and rear vertical rods; and side anti-collision supporting rods are movably riveted among the rear vertical rods, the double longitudinal beams and the front vertical rods. According to the spatial truss type steel tube frame with the solid structure, as heights are available between the top frames and the chassis underframe, a battery pack, which comparatively occupies more space, is reasonably placed and arranged so that the partial battery pack with larger weight can balance the counterweights of the front and rear vertical rods as much as possible; and therefore, higher operation performance of the vehicle can be adjusted.

Description

technical field [0001] The invention relates to the design field of a space truss type steel pipe frame, in particular to a space truss type steel pipe frame with a firm structure. Background technique [0002] In electric racing, it is common to see the space frame of the vehicle, which can include an anti-roll cage to give the frame strength and occupant protection in the event of a rollover. Frames are generally required to withstand severe loads due to sudden impacts on the vehicle; for example, bumping into objects such as boulders, trees and fenders, driving over uneven terrain and falling into cavities. This impact will further stress the frame (eg twist) by creating an imbalance relative to the frame (eg a front wheel hitting a boulder with a load on only one front corner). Spaceframe weight is also a primary consideration. It is generally desired that the space frame be as light as possible to increase vehicle speed, agility and fuel economy, and to reduce the mat...

AI Technical Summary

Problems solved by technology

The traditional method of electric racing cars is a steel structure chassis. The car shell is formed of glass fiber reinforced plastic and connected to the chassis. Because glass fiber reinforced plastic is not degradable, and it is too heavy, and it is difficult to repair for minor collisions, it cannot provide sufficient disassembly and maintenance for battery packs and batteries. And the shortcomings of collision safety, the market is in urgent need of a new space truss-type steel pipe frame that can ensure the strength and safety of the car body, and is light and environmentally friendly.
