 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1至图5所示，为本发明提供的一个较佳实施例。
本实施例提供的电动汽车1用密封系统10，其包括用于封堵车门9与车身2之间间隙的密封管1001，该密封管1001固定安装在车身2上并与车门9对应的位置，密封管1001的内部具有空心通道10011；密封系统10还包括与密封管1001的空心通道10011连通的气源1011，气源1011与设置在车身2内的电控模块相连接，电控模块在车门9闭合后控制气源1011对密封管1001充气使其膨胀。
上述的电动汽车1用密封系统10，在车门9与车身2之间设置有密封管1001，通过与该密封管1001连接的气源1011对密封管1001充气使其体积膨胀，体积倍增后的密封管1001使车身2与车门9之间的间隙得到封堵，这样，包裹在车门9边缘的接触面积更大，由于密封管1001内填充有气体，密封管1001具有较大的弹性形变，使得封堵效果更佳，不易因管体的老化而影响车门9的密封性。
本实施例中，密封管1001可采用耐臭氧老化的三元乙丙橡胶、或是具有较好弹性的热塑性弹性体制成，即保证密封管1001具有弹性体的优良工程性能，又具有塑料的优良特性，方便加工，且可回收重复利用。
参见图1，上述的车身2上由前至后顺序设有前行李舱201、乘员舱202和后行李舱203，电动汽车1的乘员舱202上方罩设有能够相对开合的前厢门901和后厢门902，车身2内的乘员舱202前部与前厢门901对应，后部与后厢门902对应，当前厢门901和后厢门902处于闭关状态时，前厢门901、后厢门902与车身2围合密封乘员舱202；密封系统10还包括于用于封堵前厢门901和后厢门902之间间隙的活动连接管1002，在前厢门901和后厢门902闭合时，活动连接管1002设置在前厢门901与后厢门902对接位置。这样，通过设置在前厢门901和后厢门902之间的活动连接管1002于前厢门901和后厢门902闭合时，对前厢门901与后厢门902对接位置的间隙进行封堵，使车身2的乘员舱202更好地密封。
上面描述了本发明对于应用在三厢双厢门车的基本结构，但是并不构成对本发明的限制，例如，在双门轿车、普通的两厢四门轿车、三厢四门轿车等内应用上述的密封系统10都是可行的。
在本实施例中，前厢门901具有与前行李舱201连接的第一端9011及与第一端9011相对的第二端9012，前厢门901能够绕第一端9011翻转，向外翻时打开乘员舱202的前部，后厢门902具有与后行李舱203连接的第三端9013及与第三端9013相对的第四端9014，后厢门902能够绕第三端9013并朝前厢门901相反的方向翻转；活动连接管1002安装在前厢门901的第二端9012上和/或安装在后厢门902的第四端9014上。活动连接管1002内部中空，密封管1001上开设有气孔10016，活动连接管1002上设置有与气孔10016配合的气嘴10021，当活动连接管1002随前厢门901和后厢门902闭合时，向下移动至密封管1001位置并与密封管1001接触，此时活动连接管1002的气嘴10021插入密封管1001的气孔10016内，并连通密封管1001的空心通道10011和活动连接管1002的内部空腔，在气源1011对密封管1001充气的同时，空气流入活动连接管1002内，使密封管1001和活动连接管1002同时膨胀，这样，体积倍增后的活动连接管1002使前厢门901和后厢门902之间的间隙得到封堵，这样，包裹在前厢门901和后厢门902边缘的接触面积更大，由于活动连接管1002内填充有气体，活动连接管1002具有较大的弹性形变，使得封堵效果更佳，不易因管体的老化而影响密封性。
在本实施例中，从图3可以看出，密封管1001包括一个用于封堵前厢门901与车身2之间及后厢门902与车身2之间缝隙的封堵部10012和与封堵部10012相对设置且用于连接车身2的固定部10013；封堵部10012的宽度大于固定部10013的宽度，封堵部10012的两侧分别连接有纵向侧壁10014，每一纵向侧壁10014包括从封堵部10012的边缘成弧形向内且向固定部10013延伸的弧形部10015。密封管1001可通过其弧形部10015与车身2的配合，使密封管1001固定在车身2上。
封堵部10012包括在用于接触前厢门901和后厢门902圆弧形面，在该封堵部10012上，位于圆弧形面的表面向密封管1001的固定部10013凹陷形成一个卡槽，在充气封堵过程中，前厢门901和后厢门902的边缘卡接入卡槽内，这样， 包裹性更好，密封效果更佳，而且在该卡槽处增加厚度和硬度，能在密封管1001封堵时快速对合，并能增加密封管1001的使用寿命。
活动连接管1002，其径向截面与密封管1001径向截面形状相近，包括一个用于封堵前厢门901和后厢门902之间间隙的接触部，和与接触部相对设置的连接部，该连接部用于将活动连接管1002固定安装在前厢门901的第二端9012上和/或后厢门902的第四端9014上。活动连接管1002的固定方式可与密封管1001的固定方式相同。
上述的气源1011包括用于给密封管1001充气的高压风机10111及可选择性地连通高压风机10111与密封管1001的气体换向阀10112。高压风机10111在电动汽车1开启后便开启，气体换向阀10112与电动汽车1内的电控模块连接，气体换向阀10112的输入端与高压风机10111连接，其输出端与密封管1001连接，在前厢门901和后厢门902闭合后，电控模块控制气体换向阀10112内的阀芯转动并连通高压风机10111与密封管1001，使高压风机10111能够对密封管1001内注入气体使密封管1001的体积膨胀，从而封堵间隙。
本发明还提供了电动汽车1，该电动汽车1包括车身2和车门9及上述电动汽车1用密封系统10；电动汽车1用密封系统10包括设置在车门9与车身2之间并用于封堵车门9与车身2之间间隙的密封管1001，密封管1001的内部具有空心通道10011；密封系统10还包括与密封管1001的空心通道10011连通并用于对密封管1001充气使其膨胀的气源1011；车身2上设有用于安装密封管1001的第一安装槽2021，第一安装槽2021沿车身2与车门9配合的部位延伸。
上述的电动汽车1，由于车门9与车身2之间设置有密封管1001，通过气源1011对密封管1001充气使其体积膨胀，体积倍增后的密封管1001使车身2与车门9之间的间隙得到封堵，这样，包裹在车门9边缘的接触面积更大，由于密封管1001内填充有气体，密封管1001具有较大的弹性形变，提高了电动汽车1内部的密封性，增加了电动汽车1对外界的防水、隔噪和防尘效果，进一步提升了行车过程的安全性。
在本实施例中，密封管1001置于第一安装槽2021内，第一安装槽2021的两侧顶部于密封管1001的弧形部10015对应的位置，相对地伸出两个凸缘，密封管1001通过其弧形部10015与第一安装槽2021的凸缘卡接配合，从而使密封管1001固定在车身2上。当然密封管1001也可以用螺钉、粘贴等方式固定。
在本实施例中，车身上由前至后顺序设有前行李舱201、乘员舱202和后行李舱203，乘员舱202上方罩设有能够相对开合的前厢门901和后厢门902，车身2内的乘员舱202前部与前厢门901对应，后部与后厢门902对应，当前厢门901和后厢门902处于闭关状态时，前厢门901、后厢门902与车身2围合密封乘员舱202；车身2的两侧并位于前厢门901和后厢门902之间设有立柱2023。前厢门901和后厢门902在闭合时，前厢门901和后厢门902分别与立柱2023的边缘相配合，并包围车身2内的乘员舱202。
密封系统10还包括于前厢门901和后厢门902闭合时用于封堵前厢门901和后厢门902之间间隙的活动连接管1002。在前厢门901和后厢门902闭合时，活动连接管1002设置在前厢门901与后厢门902对接位置。这样，通过设置在前厢门901和后厢门902之间的活动连接管1002于前厢门901和后厢门902闭合时，对前厢门901与后厢门902对接位置的间隙进行封堵，使车身2的乘员舱202更好地密封。
电动汽车1的前厢门901具有与前行李舱201连接的第一端9011及与第一端9011相对的第二端9012，从图1、图4和图5可以看出，前厢门901能够绕第一端9011翻转，向外翻时打开乘员舱202的前部，电动汽车1的后厢门902具有与后行李舱203连接的第三端9013及与第三端9013相对的第四端9014，后厢门902能够绕第三端9013并朝前厢门901相反的方向翻转；活动连接管1002安装在前厢门901的第二端9012上和/或安装在后厢门902的第四端9014上。前厢门901的第二端9012上和/或后厢门902的第四端9014上设置用于固定活动连接管1002的第二安装槽2022。活动连接管1002内部中空，密封管1001上开设有气孔10016，活动连接管1002上设置有与气孔10016配合的气嘴10021，当活动连接管1002随前厢门901和后厢门902闭合时，向下移动至密封管1001位置并与密封管1001接触，此时活动连接管1002的气嘴10021插入密封管1001的气孔10016内，并连通密封管1001的空心通道10011和活动连接管1002的内部空腔。
在本实施例中，密封管1001绕设在乘员舱202上且分别与前厢门901和后厢门902对接的位置，从图1、图2和图5可以看出，气嘴10021设置在活动连接管1002的两端，气孔10016位于各立柱2023的顶端。车身2上设有两个气源1011，两个气源1011对称地设置在车身2的两侧并均与密封管1001连接。每个气源1011包括用于给密封管1001充气的高压风机10111及可选择性地连通高压风机10111与密封管1001的气体换向阀10112。高压风机10111在电动汽车1开启后便开启，气体换向阀10112与电动汽车1内的电控模块连接，气体换向阀10112的输入端与高压风机10111连接，其输出端与密封管1001连接，在前厢门901和后厢门902闭合后，电控模块控制气体换向阀10112内的阀芯转动并连通高压风机10111与密封管1001，使高压风机10111能够对密封管1001内注入气体使密封管1001的体积膨胀，进而封堵车身2上结合处的间隙。
上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
