Problems solved by technology

[0004] The traditional beam column is made of iron, aluminum-magnesium alloy and other materials. The strength and rigidity of the traditional material can meet the requirements of the beam column, but its cost is high and the weight is heavy. It should not be used in today's automotive industry for light weight and low cost. requirements

Abstract

The invention discloses a plastic crossbeam pipe column structure. The plastic crossbeam pipe column structure comprises a pipe beam, wherein a first connecting piece, a second connecting piece and a third connecting piece are arranged on the pipe beam; a concave fixing seat is arranged at the end part of the second connecting piece; the fixing seat is embedded in the second connecting piece to be integrally formed, and is connected with a rotating shaft of a steering wheel; a first bracket and a second bracket are respectively arranged at two free ends of the pipe beam; and a central control iron piece is arranged in the middle of the pipe beam, and is arranged between the first connecting piece and the second connecting piece. According to the plastic crossbeam pipe column structure disclosed by the invention, the basic pipe beam and the bracket parts adopt an integrated forming and plastic injecting technology; the plastic crossbeam pipe column structure has good strength and good rigidity in different temperatures and different humidity, and is low in warping and high in dimension stability; and compared with a crossbeam pipe column made from conventional materials, a plastic crossbeam pipe column disclosed by the invention has the advantages that the weight is reduced by 40%, and the cost is reduced by 15%.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a plastic beam pipe column structure and an injection molding method thereof. Background technique [0002] The instrument panel is located directly in front of the driver, and is generally equipped with a driving odometer, a speedometer, an engine tachometer, a fuel gauge, warning lights, and signal lights. The driver can not only understand the basic driving status of the vehicle through the dashboard, but also control the air vents, audio, air conditioning and lighting, so as to ensure safety and enjoy more driving pleasure. [0003] In order to ensure that the various instruments and parts supported can work normally under high-speed driving and vibration conditions, the instrument panel and the beam column supporting the instrument panel must have sufficient rigidity, and in order to reduce the impact of external forces on the front and the co-pilot in the event of an accident Imp...
