Production materials
From the material point of view, the 2.0mm thick pipe used in the frame of general electric vehicles has low strength and is easy to break. This kind of electric car bumps under various road conditions, and the strength of the frame is slightly affected, which may be uneven and may break. The frame of the tail clock is made of high-carbon cold-rolled steel, with a thickness of 2.5mm, which is more than 25% thicker than the general one. The main frame is formed by automobile-level integrated stamping, which greatly improves the thickness and toughness, thus improving the strength of the frame.
