Description
本发明涉及一种汽车及其他交通工具风挡设备,尤其涉及一种风挡网状层叠式气幕生成装置。
随着现代社会的发展,汽车已成为人们不可或缺的交通工具,而汽车风挡雨刷设备是车辆行驶中帮助车辆清除雨雪的必要工具,使驾驶者能够保持清晰的驾驶视线。同时,诸如轨道交通车辆等具有风挡设备的交通工具,对于风挡雨刷设备仍必不可少。虽然车辆风挡雨刷设备的技术不断进步,但其基本原理仍是通过电机带动橡胶雨刮器清除风挡玻璃上的雨雪物质,而雨刮器往复运动及橡胶雨刮胶条的老化,会造成车辆驾驶者视觉不适、雨雪清除不净、机械老化噪声较大等弊端,极易导致驾驶者的错判与误操作,危及驾驶安全。
由于车辆行驶过程中,雨雪迎风不断散落在风挡玻璃上,影响驾驶者视线,利用空气动力学与气幕技术使迎风面向车辆的雨雪不接触风挡玻璃,即雨雪无法散落在风挡玻璃上,雨雪沿风力方向甩出,驾驶者即可获得良好的驾驶视线,没有视觉不适,这既可以替代传统风挡雨刷设备,又可以极大地提供驾驶安全性和舒适性,对于汽车及其他交通工具的设计制造技术发展具有良好的意义。如中国专利CN201510283488.8《一种气幕自洁防雨装置》公开了利用气幕喷气口并可调节喷气口喷出气体角度,将附着在车窗上的雨雪除去,从而取消传统风挡雨刷设备的技术方案,但是该专利技术方案中仍存在着喷气口数量较少、空气动力较弱的缺陷,如喷气口堵塞或调节电机损坏,会导致车辆无法行驶被迫停在道路上的安全问题;而工作电压12V的气泵空气动力较弱,会造成喷气口末端输出气体压力较弱的问题。中国专利CN201610937941.7《风能在车辆内部及外部的利用方法以及风挡气幕装置》公开了利用车辆运行中获得的风能及提供一种风挡气幕装置的技术方案,但是该技术方案中仍存在车辆低速运行时获得的风能较弱,且结构复杂,输出气幕空气不可控等缺陷,导致车辆低速运行时仍存在驾驶视线受阻的问题。
本发明针对上述现有技术的不足,提供一种风挡网状层叠式气幕生成装置,能够在风挡表面形成网状层叠气幕层,具有结构简单、性能稳定、气幕气体压力强、可控与可持续性好等优点。
本发明的技术方案是:一种风挡网状层叠式气幕生成装置,包括气幕动力装置与气幕喷口装置,所述气幕动力装置由压缩空气动力源、空气滤清器、减压阀、油雾器、蓄能器、空气增压器及调节阀依次排列布置构成;所述气幕喷口装置由U型连接气管、喷气气道及气幕喷嘴构成,U型连接气管与所述气幕动力装置的空气气管连接,并通过喷气气道上设置的进气连接孔与喷气气道连接,喷气气道上设置交错排列的气幕喷嘴,相邻气幕喷嘴间相对喷气气道轴线的夹角在5°~15°之间,临近风挡的气幕喷嘴与风挡之间的相对夹角在10°~20°之间。
进一步的方案是:所述交错排列的气幕喷嘴设置为第一排列气幕喷嘴与第二排列气幕喷嘴,第一排列气幕喷嘴临近风挡。

所述空气增压器对经所述减压阀稳压控制后输出的压缩空气进行增压,经增压后的压缩空气输出压力为原气压的2~5倍。
所述调节阀对经所述空气增压器增压输出的压缩空气进行气压大小的调节,压力调节范围在1~3.5Mpa之间,设置3~4个压力调节档次。
所述喷气气道的外形结构与风挡的外形结构相匹配。
所述压缩空气动力源为超级风机、微型空压机、高压风机中的一种,其工作电压为36V、48V、110V、220V中的一种,利用车辆蓄电池通过电源逆变器提供与所述压缩空气动力源相匹配的电压。
本发明的有益效果在于:采用上述技术方案,驾驶者在驾控车辆时,气幕动力装置即处于运行状态,即:利用车辆蓄电池通过电源逆变器提供给压缩空气动力源相匹配的电压,电压范围可在36V、48V、110V、220V之间,如微型空压机,110V工作电压;压缩空气动力源运行工作,为装置内空气管道提供持续的压缩气体,经增压后气体压力可达到原气压的2~5倍,从而使气幕喷口装置末端气压保持较高输出压力;气幕动力装置上设置的调节阀关闭时,当达到设定压力值后,压缩空气动力源停止工作,***内部维持气体压力,转为保压状态;当驾驶者操控调节阀时,可依据车辆不同行驶速度,3~4档压力调控,使不同压力值的压缩气体进入气幕喷口装置,经U型连接气管、喷气气道,从交错排列的气幕喷嘴喷出,从而在风挡表面、驾驶者安全可视范围内形成一个网状层叠的气幕层,达到阻挡雨雪散落在风挡玻璃表面,使驾驶者保持良好的视线。
与现有技术比较,本发明气幕生成装置在车辆行驶过程中,始终保持运行工作状态,由于采用了高工作电压的压缩空气动力源设备,能够输出较高压力气体,并通过增压确保气幕喷口装置末端喷出气体的压力。同时,利用蓄能器储能功能及调节阀多档次压力调控,使压缩空气动力源可间歇性工作,即达到设定压力后停止工作,而***内压力始终保持恒定,从而延长设备使用寿命,也进一步提高了整体装置的稳定性,具备可控、可持续好的优点。交错排列设置的气幕喷嘴结构,能够在风挡表面,即驾驶者安全可视范围内形成一个网状层叠的气幕层,达到多层气幕交织层叠覆盖的雨雪阻挡功能,且在少量喷嘴堵塞时依然能够形成维持阻挡雨雪散落的气幕层,避免气幕喷嘴堵塞或损坏带来的安全问题。
所述空气滤清器能够净化清洁压缩空气中的灰尘杂质及水分,提高装置稳定性;所述油雾器可对***内增压装置部件进行润滑,对不方便加润滑油的部件进行润滑,大大延长部件的使用寿命;通过电源逆变器将车辆蓄电池12V变压提高到匹配高工作电压的压缩空气动力源,满足生成气幕高气压值的要求,整体上又提升了装置工作稳定性与可持续性。
本发明所提供的风挡网状层叠式气幕生成装置具有结构简单、性能稳定、气幕气体压力强、可控与可持续性好等优点,解决了现有技术中存在的气幕末端气体压力较低,气幕喷口堵塞或损坏带来气幕层消失及不可控等问题,极大提升车辆性能,达到雨雪天驾驶视线无遮挡,挡雨挡雪效果好,易于实施、经济适用的目的。

结合本发明的实施例说明是:当驾驶者在驾控车辆时,气幕动力装置1即处于工作运行状态,即:利用车辆蓄电池4通过电源逆变器3为压缩空气动力源11提供相匹配的工作电压,电压范围可在36V、48V、110V、220V之间,如微型空压机,即110V工作电压;压缩空气动力源11运行工作,为***内空气管道提供持续的压缩气体。
压缩空气动力源11输出的气体经空气滤清器12过滤清洁后,通过减压阀13稳压控制与蓄能器15储能功能的配合作用,经空气增压器16增压后,气体压力可达到原气压的2~5倍,从而使气幕喷口装置2末端气压保持较高输出压力;当气幕动力装置1上设置的调节阀17关闭时,随着***内气体压力持续升高到所设定的压力值后,压缩空气动力源11停止工作,***内部维持气体压力,转为保压状态。
当下雨下雪时,驾驶者操控调节阀17,并可依据车辆不同行驶速度进行3~4挡压力调控,使不同压力值的压缩气体进入气幕喷口装置2,经U型连接气管21、喷气气道22,从交错排列的气幕喷嘴23喷出,特别地,交错排列的气幕喷嘴23设置为第一排列气幕喷嘴23a与第二排列气幕喷嘴23b,相邻气幕喷嘴间即第一排列气幕喷嘴23a与第二排列气幕喷嘴23b,相对喷气气道22轴线设置有5°~15°的夹角α;临近风挡5的第一排列气幕喷嘴23a与风挡5之间设置有10°~20°的夹角β;由于交错排列的气幕喷嘴结构方式,参见图3、图4、图5,从而在风挡5表面,即驾驶者安全可视范围内形成一个网状层叠式的气幕层6,覆盖在风挡5表面,达到阻挡雨雪散落在风挡5玻璃表面,并引导雨雪分流,使驾驶者保持良好的视线。
进一步的说明是,油雾器14可对***内增压装置部件进行润滑,对不方便加润滑油的部件进行润滑,大大延长部件的使用寿命。所述电源逆变器3是将车辆12V蓄电池4的电压提高到所述压缩空气动力源11相匹配的工作电压,满足生成气幕高气压值的要求,整体上又提升了装置工作稳定性与可持续性。
更进一步的说明是,假若风挡玻璃倾角为60度的车辆,行驶速度120km/h,即为33m/s,雨滴以速度V1=0.5~20m/s下落,按雨滴下落最大速度V1=20m/s计算,参见图5,雨滴下落过程中有两个分运动,即垂直下落运动V1与相对于车辆行驶方向反向的水平运动V2,那么雨滴相对于车辆的运动速度V3≈33m/s,而雨滴下落过程中实际相对于车辆的运动速度V3可达40m/s,即当车辆以120km/h速度行驶时,雨滴以V3≈40m/s速度落向风挡5的表面。本发明技术方案的气幕生成装置启动,交错排列的气幕喷嘴23沿水平方向的70~75度吹出高压气体,高压气体速度可达55m/s,形成网状层叠式的气幕层6,将雨滴阻挡在风挡5外部,并使雨滴沿车辆顶部飞出,从而达到挡雨目的。
假若风挡玻璃倾角为35度的车辆,行驶速度80km/h,即22m/s,雨滴以速度V1=0.5~20m/s下落,按雨滴下落最大速度V1=20m/s计算,雨滴下落过程中有两个分运动,即垂直下落运动V1与相对于车辆行驶方向反向的水平运动V2,那么雨滴相对于车辆的运动速度V3≈30m/s,即当车辆以80km/h速度行驶时,雨滴以V3≈30m/s速度落向风挡5的表面。本发明技术方案的气幕生成装置启动,交错排列的气幕喷嘴23沿水平方向的45~50度吹出高压气体,高压气体速度可达35m/s,形成网状层叠式的气幕层6,将雨滴阻挡在风挡5外部,并使雨滴沿车辆顶部飞出,从而达到挡雨目的。
本发明技术方案在不同雨量和车辆行驶速度下的网状层叠式气幕层测试表明:通过空气增压器16的增压与调节阀17的分档压力调控,可提高气幕喷嘴23的喷出气体压力,并能根据雨量与车辆速度合理调节;交错排列的气幕喷嘴结构,能够形成一个网状层叠的气幕层6,即使出现少量喷嘴堵塞或损坏时,也能够形成维持阻挡雨雪散落的气幕层,有效阻挡雨雪对车辆风挡玻璃的冲击;同时,通过电压逆变处理与蓄能保压,极大提升了整个装置的可持续性与使用寿命。
本发明技术方案测试条件如下表:
本发明技术方案在不同雨量与行驶速度条件下的测试结果如下表:

以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的具体实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。
