The invention discloses a typical structure of a mixed material instrument panel cross beam, which comprises a tubular beam and vehicle body mounting brackets arranged at the two ends of the tubular beam, the tubular beam is further provided with an IP support used for installing an instrument desk, a steering column installing support used for being connected with a steering system, a front wall support used for being connected with an automobile front wall and a middle channel support used for being connected with a floor. Wherein the vehicle body mounting bracket, the IP bracket, the front wall bracket and the middle channel bracket are injection molding parts made of plastics, and the tubular beam is a steel tube; the invention further discloses a manufacturing method of the typical structure of the mixed material instrument panel cross beam. By combining a steel part with an injection molding material, compared with a steel structure instrument panel cross beam, the weight can be reduced by 25%, compared with aluminum alloy and magnesium alloy instrument panel cross beams, the cost is low, meanwhile, the injection molding process is adopted to replace a welding process, and the production quality of the instrument panel cross beam is guaranteed.

    本发明公开了一种混合材料仪表板横梁的典型结构,包括管梁以及设置在所述管梁两端的车身安装支架,所述管梁上还设置有用于安装仪表台的IP支架、用于连接转向系统的转向管柱安装支架、用于连接汽车前围的前围支架、用于连接地板的中通道支架;其中,所述车身安装支架、所述IP支架、所述前围支架、所述中通道支架为塑料形成的注塑件,所述管梁为钢管;本发明还公开了一种混合材料仪表板横梁的典型结构的制造方法。本发明通过将钢制件与注塑材料相结合,相比于钢结构仪表板横梁,可减重25%,相较于铝合金、镁合金仪表板横梁,成本较低,同时采用注塑工艺代替焊接工艺,保证了仪表板横梁的生产质量。
