具体实施方式
以下结合较佳实施例及其附图对本发明技术方案作进一步非限制性的详细说明。显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1-4,本发明提供技术方案:一种电动汽车充电桩电缆,包括充电插头1,充电插头1的一侧连接有电缆3,充电插头1的一侧设置有充电插座2,充电插座2设置在外部电动汽车上,充电插座2的一侧均匀开设有圆孔21,圆孔21的内部安装有导电端子22,充电插头1的一侧均匀设置有端子导向柱11,端子导向柱11与导电端子22电连接,端子导向柱11上开设有缺口111,端子导向柱11具有弹性形变能力,端子导向柱11的内壁为导电材质,在使用时首先将充电插头1插入充电插座2上,使得端子导向柱11与导电端子22相互套接,此时将缺口111进行挤压,可以使得其内壁的导电部分开始导电,此时可以开始充电,同时此时会对导电端子22具有一定的挤压力,防止其脱落;
端子导向柱11的内壁开设有容置槽112,容置槽112的内部滑动设置有上紧条16,位于各个端子导向柱11上的上紧条16的一端共同连接有柔性带12,充电插头1的内壁通过轴承转动安装有卷绕辊15,柔性带12缠绕在卷绕辊15的外壁,在充电时正向旋转卷绕辊15,可以将柔性带12缠绕在其外壁,同时能够将柔性带12进行束紧,柔性带12的一端拉动带动上紧条16进行束紧操作,可以使得缺口111密合,此时通电且会产生一定的连接阻力,防止充电插头1脱落,同时由于无需外部的固定件,充电过程方便,在充电完毕时反向旋转卷绕辊15使得柔性带12松开,端子导向柱11由于弹性恢复力又会形成缺口111,此时可以很方便地将充电插头1取下,便于插拔过程中降低摩擦力,提高充电插头1的使用寿命;
卷绕辊15的一侧通过焊接连接有蜗轮183,蜗轮183与充电插头1的内壁转动连接,充电插头1的一侧内壁转动安装有连接轴182,连接轴182的外部套接有蜗杆181,蜗杆181与蜗轮183相螺接,当进行充电时先将端子导向柱11与导电端子22相互插接,再驱动蜗杆181旋转,蜗杆181带动蜗轮183转动,由于蜗轮蜗杆机构具有自锁性能,可以防止其反转,使得端子导向柱11在充电时始终闭合,防止其断开;
连接轴182的一端连接有卡齿盘18,充电插头1的一侧内壁安装有导轨17,导轨17的内壁滑动连接有控制拉条14,控制拉条14与卡齿盘18相啮合,通过拉动控制拉条14可以控制卡齿盘18转动,从而带动连接轴182转动,使得蜗杆181转动,将旋转驱动转变为直线驱动,由于旋转驱动会在拆卸时产生扭力,会使得端子导向柱11与导电端子22产生松动,但变为直线驱动力则会顺应插头插拔的方向,力的方向不是扭转而是直线,不会因为频繁插拔导致端子导向柱11与导电端子22的配合因为扭力而松动,同时由于不是直接驱动,可以避免插拔过程中的触电隐患;
充电插头1的一侧开设有通孔13,控制拉条14弯折并穿过通孔13,控制拉条14的一端与充电插头1的内壁相固定,当拆卸时向外拉动控制拉条14移动,当充电时向内推挤控制拉条14移动,可以驱动蜗杆181正转或反转,同时充电时由于控制拉条14嵌入其内部,防止小孩误触的现象;
充电插头1的两侧对应设置有横向限位组件4,横向限位组件4包括接触板47,充电插头1的一侧开设有U型槽41,U型槽41的内壁通过轴承转动连接有支臂45,支臂45的一端内部套接有调向轴46,调向轴46的两端连接有接触板47,接触板47与充电插座2的侧壁相接触,由于当支臂45的角度调整时会将接触板47贴合在充电插座2上,进行夹紧,用于阻挡充电插头1与充电插座2的左右晃动,在充电完毕时用手向边缘扳动支臂45,使得接触板47不再阻挡充电插头1的移动,从外耳内加强充电过程的稳定性;
U型槽41的一侧向内凹陷设置有延伸槽42,延伸槽42的内部滑动安装有方形块43,方形块43与支臂45为配合结构,方形块43的顶部连接有拨块44,通过拉动拨块44使方形块43挡住支臂45的运动,从而限制充电插头1的横向位置,使得其始终朝向前方并进行夹紧,增加着力点,在插拔时防止左右摇晃的施加力量导致的松动现象;
端子导向柱11的长度大于圆孔21的深度,且柔性带12不与充电插座2的侧壁相接触,导电端子22具有小幅度热胀冷缩性能,所述导电端子22受热膨胀时撑开缺口111,当电路短路时,由于电流增大,导电端子22受热膨胀强行撑开端子导向柱11,使得端子导向柱11内壁的导电材质相分开,内部的通电回路直接断开,便于防止短路损伤汽车,提高安全性。
在本发明的描述中,需要理解的是,术语“ 上”、“ 下”、“ 前”、“ 后”、“ 左”、“右”、等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。
最后需要指出的是:以上实施例仅用以说明本发明的技术方案,而非对其限制。尽管参照前述实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
