Description

一种汽车透明A柱显示***A car transparent A-pillar display system 技术领域technical field
本发明涉及汽车技术领域，更具体的说，涉及一种汽车透明A柱显示***。The invention relates to the technical field of automobiles, and more particularly, to a transparent A-pillar display system for automobiles.
背景技术Background technique
汽车A柱是指汽车左前方和右前方连接车顶和前舱的连接柱，在发动机舱和驾驶舱之间，左右后视镜的上方，会遮挡一部分的转弯视界，形成汽车A柱盲区。The A-pillar of a car refers to the connecting column connecting the roof and the front cabin in the front left and right of the car. Between the engine compartment and the cockpit, above the left and right rearview mirrors, part of the turning vision is blocked, forming a blind spot for the A-pillar of the car.
汽车A柱在视野和刚度之间存在矛盾，尺寸过小会导致车身强度不足，太大又会影响驾驶员视野。There is a contradiction between the visual field and the stiffness of the car A-pillar. If the size is too small, the body strength will be insufficient, and if the size is too large, the driver's field of vision will be affected.
一方面，当汽车在转弯或者进入弯道前，驾驶者的视野都会被A柱部分遮挡，造成一个视野上的盲区，汽车A柱会遮挡一部分视线，容易在转弯时出现事故，从这个角度来说，汽车A柱越薄越好。On the one hand, when the car is turning or entering a curve, the driver's field of vision will be partially blocked by the A-pillar, resulting in a blind spot in the field of vision. The A-pillar of the car will block part of the line of sight, which is prone to accidents when turning. From this angle That said, the thinner the car's A-pillars, the better.
另一方面，A柱又要保证一定的刚度，以减小安全的风险。On the other hand, the A-pillar must ensure a certain rigidity to reduce the risk of safety.
因此，汽车A柱的透明化是汽车的发展趋势。现有的汽车透明A柱多是利用折射的原理，让视线发生弯曲和折射的处理，最终让司机看到的结果将是A柱后方的障碍物。但是，该方法视物不清，仍无法有效的成为完全透明的汽车A柱。Therefore, the transparency of automobile A-pillars is the development trend of automobiles. Most of the existing transparent A-pillars of automobiles use the principle of refraction to bend and refract the line of sight. The final result for the driver to see will be the obstacles behind the A-pillars. However, this method has unclear vision, and still cannot effectively become a completely transparent automobile A-pillar.
