The invention provides a stand column assembly and a vehicle. The stand column assembly comprises a support and stand column glass, the stand column glass is arranged on the outer side of the support, the stand column glass has surface hardness HV and a first thermal expansion coefficient CTE1, the surface hardness HV is larger than or equal to 500, and the first thermal expansion coefficient CTE1 is smaller than or equal to 80 * 10 <-7 >/DEG C. According to the stand column assembly, the stand column glass with the surface hardness HV larger than or equal to 500 and the first thermal expansion coefficient CTE1 smaller than or equal to 80 * 10 <-7 >/DEG C is adopted, so that the stand column glass has excellent friction resistance, crack propagation can be reduced, scratches and abrasion of the stand column glass are reduced, the appearance performance of the stand column glass is improved, and the service life of the stand column glass is prolonged; the maintenance cost is reduced; in addition, the influence of scratches of the stand column glass on the sensing assembly is reduced, and the working effect of the sensing assembly is improved.
本申请提供了立柱总成及车辆。立柱总成包括支架、及立柱玻璃,立柱玻璃装设于支架的外侧,立柱玻璃具有表面硬度HV和第一热膨胀系数CTE1,表面硬度HV≥500,第一热膨胀系数CTE1≤80X10‑7/℃。本申请提供的立柱总成,通过采用表面硬度HV≥500、及第一热膨胀系数CTE1≤80X10‑7/℃的立柱玻璃,使立柱玻璃既具有优秀的抗摩擦性能,又能够减少裂纹扩展,从而减少了立柱玻璃的划痕和磨损,提高了立柱玻璃的外观性能,延长了立柱玻璃的使用寿命,减少了维护成本;另外,还减少了立柱玻璃的划痕对传感组件的影响,提高了传感组件的工作效果。
