Description
技术领域
本发明属于汽车领域，涉及汽车油箱，具体涉及嵌套式防撞击防静电汽车油箱。
背景技术
汽车油箱是汽车储存汽油或柴油的容器，除了储油外，汽车油箱还需满足散热、除静电、防漏、防爆等多个功能。一个设计良好、考虑全面的油箱，往往能够将危险消弭于无形，为驾驶提供安全保障。
目前的油箱主要有两种材质，塑料和铁质，由这两种材料分别对应了两种特定不同的油箱：铁质油箱，作为一种传统的油箱，具有较强的刚性，在外力冲击下，能够较好的保证油箱结构的完整；同时，铁质材料由于较好的热胀冷缩特性，在极寒或极热等恶劣温度下，变形较小，整体刚性更好；铁质本身不会渗透蒸发气体，较少出现发动机自燃等事故；同时铁质油箱可以通过表面处理来防锈、防腐，使用寿命均较长，再加上良好的导电性，铁质油箱可通过电连接蓄电池负极来有效规避油箱静电。但是由于金属加工的特性，铁质油箱往往通过多块特定形状的铁板焊接而成，撞击时，焊缝处强度较弱，容易断裂进而漏油，引发事故；同时，铁质油箱相对较重，无法设计较复杂的形状，以及长期使用过程中容易发生的水分、酸性锈蚀，都影响了铁质油箱的应用与发展。塑料油箱：在塑料工业高速发展的背景下，塑料油箱由于其重量轻、能一次成型较复杂的形状这两个突出优势，成为了当今油箱市场的宠儿。但是，塑料油箱难以修复，寒冷环境下的耐冲击性能较差，高温下的透过塑料油箱壁渗油现象，易于燃油中添加剂反应，热变形温度较低，无法有效防止静电危害等缺点，都大大限制了塑料油箱的进一步发展。
现有技术中往往通过向塑料中添加特定物质，安装复杂的防静电，收集渗油渗气装置来减少事故率，但是这些方法都无法从根本上解决问题，还使结构愈加复杂化，成本更高。
发明内容
针对以上技术问题，本发明的发明目的是提供一种防腐防锈、防静电、防渗油渗气、极寒极热下机械性能优秀、在强烈冲撞下防撞击、防漏油、防爆炸，并且质量相对较轻的汽车油箱。
本发明解决该技术问题所采取的技术方案为：
具有钛合金内胆的嵌套式防撞击防静电汽车油箱，包括金属油箱内胆(1)，其特征在于：还包括塑料箱体(2)，所述金属油箱内胆(1)嵌套安装于所述塑料箱体(2)内部，所述塑料箱体(2)的上方安装一塑料盖体(15)，所述金属油箱内胆(1)和塑料箱体(2)之间填充有缓冲橡胶层(3)；
所述塑料箱体(2)内部侧面均布有竖直导油槽(4)，塑料箱体(2)内部底面步有水平导油槽(5)，所述水平导油槽(5)联通有储油瓶(6)，所述储油瓶(6)的入口位置低于所述水平导油槽(5)；
所述的储油瓶(6)外包保护海绵(7)；
所述的金属油箱内胆(1)焊接有静电导线(8)；
所述的金属油箱内胆(1)由钛合金板材焊接而成，焊接后其表面经防锈防腐电镀处理。
进一步的，作为本发明的改进，其特征在于：所述的金属油箱内胆(1)上焊接有第一油嘴(9)和第二油嘴(10)，所述第一油嘴(9)具有双层同轴漏斗结构，其外层的漏斗结构出口处有滤油网(11)，所述滤油网(11)出口通过回油油管(12)连接至所述第二油嘴(10)。
进一步的，作为本发明的改进，其特征在于：所述的储油瓶(6)具有储油瓶出口(13)，所述储油瓶出口(13)通过储油瓶油管(14)连接至所述第二油嘴(10)。
进一步的，作为本发明的改进，其特征在于：所述的储油瓶出口(13)位于储油瓶(6) 的底面上。
进一步的，作为本发明的改进，其特征在于：所述的储油瓶出口(13)位于储油瓶(6) 的侧面靠近底面1/2瓶高到1/5瓶高处。
采用本发明所取得的有益技术效果为：
油箱内层与油品接触的箱体为金属材料，有效杜绝了采用塑料油箱带来的渗油渗气现象；同时有效保证了油箱整体结构的刚性，在高温差下，金属由于具有较好的导热性和延展性，使油箱在极热或极寒的条件下具有较强的维持结构的稳定性；最后，借用金属良好的导电性，通过添加简单的静电导线，有效规避油箱静电危害。
油箱外层与空气接触的箱体为塑料材料，首先防止油箱直接与水分接触，大大降低锈蚀的风险，同时利用塑料整体成型的加工方式，有效应对当金属油箱受冲击而焊缝破裂漏油时产生的危险，用塑料箱体承接泄露的燃油并收集，有效避免了由于金属油箱焊缝断裂所引起的燃烧甚至爆炸的现象。
油箱内层与油箱外层之间填充缓冲橡胶，不但有效减少驾驶过程中由于颠簸行驶对油箱带来的冲击，还能在车辆失控时减少油箱受到的局部大载荷冲击，有效避免金属油箱的焊缝断裂。
油箱外层的塑料箱体底部具有收集残油的油路及与之配套的储油瓶，可在金属油箱破裂时收集由其裂缝处流出的燃油，使之不至于流出油箱范围，接触火源，引发危险。
油箱内层的金属箱体内表面经过防腐防锈的电镀处理，减少由于油品中的水分、催化剂和其他有机成分对于箱体表面的腐蚀。
油箱油嘴同样进行了回油设计，以避免从油嘴处泄露出的燃油所引发的危险，并将从油嘴处泄露的燃油经过过滤处理，流经油管和储油瓶回流至油箱。
承接回油和漏油的储油瓶同时外覆防撞材料，避免其受到冲击所引起的事故。
