Description

说明书 发明名称：一种带可伸缩接触头的车载取电装置及其生产方法
[0001] 技术领域
[0002] 本发明涉及车载设备技术领域， 特别涉及一种带可伸缩接触头的车载取电装置 及其生产方法。
[0003] 背景技术
[0004] 车载取电装置， 是随车使用的日常充电设备， 用于将车内点烟器的取电口中的 电源转化成移动电子设备可以使用的充电接口， 大大提高了司乘人员的随身电 子设备的续航问题。 现有的车载取电装置在接入取电口后， 随着汽车的行驶颠 簸在震动， 容易出现车载取电装置与取电口电极接触不稳定， 尤其是车上无卡 扣位置的充电口接触更不稳定， 无法稳定提供的充电功能。
[0005] 发明内容
[0006] 针对现有技术的上述缺陷， 提供一种带可伸缩接触头的车载取电装置本发明解 决其技术问题所采用的技术方案是：
[0007] 一种带可伸缩接触头的车载取电装置， 其包括壳体， 壳体下端的外径与车载点 烟器的内径相等， 壳体内设有电源适配器， 壳体下端设置有电源适配器第一电 极触点， 壳体连接有接触头， 接触头的顶部为电源适配器的第二电极触点， 壳 体上端有充电口， 充电口与电源适配器连接， 其特征在于： 壳体上有限位件， 限位件与接触头设置有互相咬合的卡扣结构， 接触头和限位件通过卡扣结构组 成相对滑动的卡扣活塞结构， 壳体内设置有弹簧， 弹簧的一端顶住接触头。 使 用吋由于弹簧张力始终将接触头顶向触点， 所以在颠簸和碰触的情况下始终能 保持电极的导通。
[0008] 优选的， 接触头下表面从内到外设置有内柱体和外柱体， 外柱体外表面设置有 外柱卡扣； 限位件相对内柱体和外柱体设置有相互吻合的内限位柱和外限位柱 ， 外限位柱设置有与外柱卡扣卡合的限位卡扣， 弹簧通过内柱后顶住接触头。 这种结构能使接触头更稳定的与限位件配合， 做活塞运动吋减少晃动。
[0009] 优选的， 接触头边缘超出或平齐外柱。 接触头边缘超出外柱吋形成一个扣口， 扣口与点烟器内部的扣件相配合。
[0010] 优选的， 外柱卡扣一端有斜面， 一端为直角； 限位卡扣一端有斜面， 一端为直 角； 外柱卡扣斜面端和限位卡扣斜面端相对设置。 这种结构在装配吋， 斜面便 于活塞结构的安装， 安装好后， 直角使活塞不易于滑幵。 在装配吋可以用强压 法或者热缩法。
[0011] 优选的， 电源适配器第一电极触点设置在壳体上的一圈外凸起上。 凸起与取电 口内径紧配。
[0012] 优选的， 壳体上幵有一对通孔， 电源适配器第一电极触点为一对弹性卡簧， 弹 性卡簧位于壳体的通孔内。
[0013] 优选的， 接触头顶部为锥型。 锥型顶部也可以设置为安全锤。
[0014] 一种带可伸缩接触头的车载取电装置卡扣活塞结构的生产方法， 其特征在于： 包括限位件和接触头， 壳体上有限位件， 限位件与接触头设置有互相咬合的卡 扣结构， 在生产过程中先将接触头冷却， 在限位件在 80度至 110度吋将接触头装 配入限位件， 限位件冷却后自然形成互相咬合的卡扣结构。
[0015] 优选的， 接触头为金属接触头， 限位件为塑料限位件。
[0016] 优选的， 限位件的最佳装配温度为 100度。
[0017] 本发明的有益效果是： 可以提高车载取电装置在汽车内使用吋的稳定性， 保持 车载取电装置的末端与取电口电极一直接触， 并且可以同吋在直筒式和弹片式 取电口使用。
[0018] 附图说明
[0019] 下面将结合附图及实施例对本发明作进一步说明：
[0020] 图 1为一种使用了可伸缩接触头的车载取电装置的一种优选实施例的自然状态 剖视图；
[0021] 图 2为一种使用了可伸缩接触头的车载取电装置的一种优选实施例的压缩状态 剖视图；
[0022] 图 3为卡扣活塞结构的一种优选实施例的结构剖视图；

[0025] 下面结合附图对本发明的具体实施方式进一步详细说明。
[0026] 如图 1和 2所示的一种带可伸缩接触头的车载取电装置， 其包括壳体 5， 壳体 5下 端的外径与车载点烟器的内径相等， 壳体 5内设有电源适配器 （图中未显示） ， 壳体 5连接有接触头 1， 壳体 5上端螺纹链接有充电口 6， 充电口 6与电源适配器连 接， 其特征在于： 壳体 5上有限位件 2， 限位件 2与接触头 1设置有互相咬合的卡 扣结构， 接触头 1和限位件 2通过卡扣结构组成相对滑动的卡扣活塞结构， 壳体 内设置有弹簧 3， 弹簧 3的一端顶住接触头 1。
[0027] 如图 3所示的接触头 1， 顶部 101下表面从内到外设置有内柱体 103和外柱体 102 ， 外柱体 102外表面设置有外柱卡扣 104， 顶部 101边缘超出外柱体 102， 而且接 触头 1的顶部 101为凸出体； 限位件 2相对内柱体 103和外柱体 102设置有相互吻合 的内限位柱 201和外限位柱 202， 外限位柱 202设置有与外柱卡扣 104卡合的限位 卡扣 203。
[0028] 接触头 1为金属接触头， 限位件 2为塑料限位件。
[0029] 外柱卡扣 104—端有斜面， 一端为直角； 限位卡扣 203—端有斜面， 一端为直角 ； 外柱卡扣 104斜面端和限位卡扣 203斜面端相对设置。 在生产吋， 先将接触头 1 冷却， 当限位件 2在 80-110度吋将接触头 1装配入限位件 2， 最好选择在 100度吋将 接触头 1转配进入限位件 2中， 限位件 2冷却后自然形成互相咬合的卡扣结构。
[0030] 弹簧 3通过内柱体 103后顶住接触头 1的顶部 101。
[0031] 接触头 1的顶部 101为电源适配器的第二电极触点； 壳体上幵有一对通孔， 电源 适配器第一电极触点为一对弹性卡簧 4， 弹性卡簧 4位于壳体的通孔内。 当取电 装置放进点烟器的取电口吋， 顶部 101和弹性卡簧 4都接触到电极后， 电源适配 器中电路导通， 幵始正常使用。
[0032] 使用吋， 将一种使用可伸缩接触头的车载取电装置放置到车中的取电口， 接触 头 1触碰到取电口的电极， 充电口 6可以接入充电器进行充电作业。 但汽车行驶 过程颠簸吋， 取电器发生位移， 接触头 1在弹簧 3的弹性力的作用下向前顶， 使 得接触头 1继续与第二电极保持接触。 整个结构简单， 而且适用于直筒式和弹片 式取电口， 应用范围广。 [0033] 在本发明的另一优选实施例中， 限位件 2为壳体 5， 也就是说限位件 2和壳体一 体成型结构。
[0034] 在本发明的另一优选实施例中， 限位件 2为金属材料制造而成， 装配吋， 接触 头 1上的外柱卡扣 104的卡扣斜面正对限位件 2上的限位卡扣 203的斜面， 通过强 压法将接触头 1压入限位件 2中， 形成互相咬合的卡扣结构。
[0035] 如上所述， 仅为本发明具体实施方式， 不能以此为限定本发明具体实施范围， 凡根据本发明权利要求及说明内容所作的变化与修改， 皆在本发明的保护范围 内。
