Description

一种风挡气幕喷气气道 技术领域
本发明涉及一种汽车及其他交通工具风挡设备，特别涉及一种风挡气幕喷气气道。
 背景技术
具有风挡的交通工具，如汽车等，驾驶过程中驾驶人员需要获得良好清晰的操作视线，以保证行驶过程中的安全。尤其是在雨雪天气条件下，通过将风挡表面的雨雪清除，并阻挡雨雪触接风挡玻璃，从而获得清晰的驾驶视野。现有的车辆雨刮装置虽然能够随雨雪大小，通过雨刮摆动快慢实现刮水效果，但雨刮条未接触风挡部分仍很快被雨雪覆盖，导致视线模糊，形成雨刮视线盲区，若能利用空气动力学与气幕技术实现雨雪不直接接触风挡的清除方式，对于车辆风挡雨雪清除方式的提升创新具有重大意义。如中国专利CN 101870283 A，公开了一种汽车配套设施装置，通过对汽车原有设备装置重新设计改造，在雨雪天需要时，开动强力开关使排风扇处于高速运转状态，经排风槽、风力导流管道、排出口排出，在风挡玻璃表面形成一层风幕墙，阻止雨雪在风挡玻璃表面的着落。但该专利文献中的风幕墙气体管路存在布置分散、气体压力较为分散等缺陷。如中国专利CN 205022544 U，公开了一种汽车前挡除雨装置，包括空气压缩机和用于连接在发动机罩盖和前挡风玻璃之间的通风盖板，所述通风盖板上开设有若干组沿汽车宽度方向分布的出风孔，所述空气压缩机通过导管与上述出风孔相连通，使空气压缩机产生高压气体，通过气流导管输送通风盖板上面的出风孔处喷出气流，直接喷射到风挡玻璃上面；上述的装置虽然能够起到清洁风挡玻璃的功能，但仍存在出风孔较为分散，喷出气流分散，不均匀与结构较为复杂等缺陷。
 技术问题
本发明针对现有技术的不足，提供一种风挡气幕喷气气道，能够有利于气道内气体压力保持一致，气体经过逐步收窄的气道空腔进一步加速加压，且使气幕喷嘴不同位置的出风口获得更加均匀一致的风力，具有结构简单实用，气幕喷嘴布置合理，输出气压均匀且能有效提高气幕喷嘴出风口风速等优点。
 技术解决方案
本发明的技术方案是：一种风挡气幕喷气气道，包括气道本体与气幕喷嘴，所述气道本体由上壳体、下壳体及两个端板构成，所述上壳体与下壳体之间形成的空腔内设置有气管，所述气管设置在所述端板上并固定；所述气道本体的上壳体上设置有以不同圆弧半径排列的第一列气幕喷嘴与第二列气幕喷嘴，所述第一列气幕喷嘴的圆弧半径比所述上壳体的上部圆弧半径大10～30㎜，所述第二列气幕喷嘴的圆弧半径比所述第一列气幕喷嘴的圆弧半径大5～25㎜，所述第一列气幕喷嘴与第二列气幕喷嘴均以所述上壳体的上部圆弧中心夹角10～15度均匀布置；所述气管两端设有进气口装置，所述进气口装置通过螺纹结构与所述气管连接。
进一步的说明，所述上壳体与下壳体之间形成的空腔结构设置为由圆弧半径比5:1～10:1的两个圆弧直线相切连接构成，其中，所述气管位于圆弧半径大的空腔内，所述气幕喷嘴位于圆弧半径小的空腔外部位置。
所述气道本体的下壳体安装倾斜角同风挡与水平面的夹角保持一致。
所述第一列气幕喷嘴设置为4～6个，所述第二列气幕喷嘴设置为5～7个。
所述气管上设置有气孔，所述气孔与气幕喷嘴相背设置。
所述上壳体与下壳体通过铆接连接。
所述气道本体的两个端板与所述上壳体、下壳体通过焊接连接。
所述进气口装置一端设置为管路连接螺母，其另一端设置为带有管路锁紧螺母的连接结构。
 有益效果
本发明的有益效果在于：所述气道本体的内部空腔设置呈流线型水滴状，靠近气幕喷嘴出风口位置逐步收窄；高压气体经气道本体内部空腔中设置的气管流入空腔内，通过将气管上开设的气孔与气幕喷嘴相背设置，使空腔内部进出前后气体的压力具有较小的压差，流线型空腔结构能够有效减少气体流动阻力，空腔内部形成更加均匀的压力，气体经过逐步收窄的气道空腔进一步加速加压，且使气幕喷嘴不同位置的出风口获得更加均匀一致的风力；气幕喷嘴布置合理，能够有效形成对风挡表面可视区域的气幕层覆盖，满足驾驶者对清晰驾驶视线的需要。
与现有技术方案比较，本发明的风挡气幕喷气气道具有如下优点：
、高压气体经过喷气气道汇聚后，从气幕喷嘴不同位置出风口喷出的气压均匀、强劲；
、不同圆弧半径排列的气幕喷嘴布置合理，能够有效形成对风挡表面可视区域的气幕层覆盖；
