Description

一种收放线装置及具有该收放线装置的充电桩 技术领域
本实用新型涉及电动车充电桩，特别涉及一种收放线装置及具有该收放线装置的充电桩。
背景技术
现有技术中，电动车是通过供应交流电的充电桩来充电。目前的国家标准中规定了关于交流充电桩与车辆的三种连接方式：第一种连接方式是将充电线设置在车辆上，在需要时可以将充电线拉出并接到充电桩上，但现有的车辆很少是按照这种方式来设计的；第二种连接方式是在充电桩和车辆上分别设置接口，并且用独立的连接线来接入，此种方式需要随车带充电线，可靠性和安全性不好，采用该种方式设计的充电桩和车辆也很少；第三种连接方式是将充电线设置的充电桩上，并且在充电线的末端设置充电枪，以便与车辆上的充电接口连接，现有的车辆和充电桩更多是采用第三种连接方式设计，不需要在车辆上设置充电线，车辆可以共用充电桩上的充电线，更加的节约资源。
然而，充电桩与车辆采用第三种连接方式，也存在很多缺陷，充电线的长度需要设置足够长，需要使充电线末端位置的充电枪能够连接至与该充电桩临近的几个车位，通常需要设置3-5米，甚至7-10米，充电桩上会设置有收线器，充电线缠绕在收线器上。现有充电桩上的收线器裸露在外，用户将充电线人工缠绕在收线器上，或者通过设置手摇杆将充电线缠绕在收线器上，但是实际使用时，用户通常随手将充电器挂于充电桩上而不会将充电线缠绕在收线器上，会使充电线堆积在地面上，被车辆碾压或者用户踩踏。
发明内容
本实用新型所要解决的技术问题是提供一种能够自动收线的收放线装置及具有该收放线装置的充电桩。
本实用新型解决上述技术问题所采用的技术方案为：一种收放线装置，包括收线筒、充电线和充电枪，所述充电线一端与供电设备连接，所述充电线的中间部分缠绕在所述收线筒的外侧壁上，所述充电线的另一端与所述充电枪固定连接，该收放线装置还包括具有驱动轴的电机和用于控制所述电机运转或关闭的控制开关，所述驱动轴与所述收线筒固定连接，所述驱动轴与所述收线筒同轴，所述电机通过所述驱动轴驱使所述收线筒转动收线，所述控制开关固定设置在所述充电枪上。
作为优选，所述充电枪的外侧壁上套设有耐磨保护套，所述耐磨保护套上开设有与所述控制开关配合的通孔，所述控制开关伸出所述通孔。
一种具有收放线装置的充电桩，包括充电桩壳体和收放线装置，所述充电桩壳体的侧壁上设置有安装口，所述收放线装置包括收线筒、充电线以及充电枪，所述充电线一端与供电设备连接，所述充电线的中间部分缠绕在所述收线筒的外侧壁上，所述充电线的另一端与所述充电枪固定连接，所述收线筒和所述充电线设置在所述充电桩壳体内，所述充电枪插装在所述安装口处，该具有收放线装置的充电桩还包括具有驱动轴的电机和用于控制所述电机运转或关闭的控制开关，所述驱动轴与所述收线筒固定连接，所述驱动轴与所述收线筒同轴，所述电机通过所述驱动轴驱使所述收线筒转动收线，所述控制开关固定设置在所述充电枪上。
作为优选，所述充电枪的外侧壁上套设有耐磨保护套，所述耐磨保护套上开设有与所述控制开关配合的通孔，所述控制开关伸出所述通孔。
作为优选，所述安装口处设置有环形橡胶圈，所述安装口的边沿与所述环形橡胶圈的外圈连接，所述环形橡胶圈的内圈开口大小与所 述充电枪的尾部相适配，所述充电枪上设有环形垫片，所述环形垫片的外直径大于所述环形橡胶圈的内圈开口直径而无法穿过所述环形橡胶圈，并且在所述充电线完全被收回时，所述环形橡胶圈被所述环形垫片作用形成肉眼易识别的凹陷锥形结构。
作为优选，所述充电桩壳体内设置有用于限制所述充电线收线和放线的运动轨迹的定位导向装置。
作为优选，所述定位导向装置包括固定设置在所述充电桩壳体的内侧壁上的第一支架和可转动的设置在所述第一支架上的第一定滑轮，所述充电线经所述第一定滑轮后与所述充电枪固定连接。
作为优选，所述定位导向装置还包括固定设置在所述充电桩壳体的内侧壁上的第二支架和可转动的设置在所述第二支架上的第二定滑轮，所述第二定滑轮和所述第一定滑轮之间形成供所述充电线穿过的间隙。
作为优选，所述控制开关包括开启按钮、关闭按钮、用于控制所述电机关闭的接近开关和与所述接近开关适配的检测块，所述开启按钮和所述关闭按钮分别固定设置在所述充电枪上，所述接近开关固定设置在所述充电桩壳体的内侧壁上，所述检测块固定设置在所述充电线上；当所述检测块跟随所述充电线移动进入到所述接近开关的检测范围内时，所述接近开关断开，按压所述的开启按钮无法使所述电机运转，当所述检测块跟随所述充电线移动离开所述接近开关的检测范围时，所述接近开关闭合，按压所述的开启按钮能够使所述电机运转。
与现有技术相比，本实用新型的优点在于：
1、本实用新型当需要充电时，用户通过充电枪拉动充电线，就可以带动收线筒正转，需要用多长的充电线，拉出多长的充电线即可。在冲完电以后，用户能够通过控制开关使电机运转，电机的驱动轴带动收线筒反转，收线筒反转时就可以自动将充电线缠绕于其外侧壁上，用户无需手动将充电线缠绕在收线筒上进行收纳，省时省力，用户的使用体验较好。
2、本实用新型通过将收放线装置设置在充电桩壳体内，以增加收放线装置使用的安全性，同时通过设置安装口，便于用户拿取和放置充电枪，使用上较为便捷。
3、本实用新型环形橡胶圈具有回弹力，在将电机开启后，用户可以通过观察环形橡胶圈是否发生形变来判断充电线的收线情况，当环形橡胶圈向内凹陷形成肉眼易识别的凹陷锥形结构时，关闭控制开关，使电机停止转动，避免充电枪与充电桩壳体硬性碰撞，有利于长久使用。
4、本实用新型初始状态时，用户未使用充电桩，充电线处于收拢缠绕状态，检测块位于接近开关的检测范围内，此时接近开关为断开状态，相应的电机处于关闭状态；当用户通过充电枪拉动充电线时，检测块跟随充电线移动并离开接近开关的检测范围，接近开关由断开状态切换为闭合状态，此时通过按压开启按钮使电机运转进行收线；当充电线收拢到初始状态时，检测块跟随充电线移动并靠近接近开关，接近开关检测到检测块并断开，同时切断电机使其处于关闭状态，完成收线动作，故用户充完电后仅需按压开启按钮即可完成收线动作，无需等待充电线完全收拢后再按压关闭按钮，方便实用。

该收放线装置还包括具有驱动轴41的电机4和用于控制电机4运转或关闭的控制开关5，驱动轴41与收线筒1固定连接，驱动轴41与收线筒1同轴，电机4通过驱动轴41驱使收线筒1转动收线，控制开关5固定设置在充电枪3上。
本实施例中，充电枪3的外侧壁上套设有耐磨保护套6，耐磨保护套6上开设有与控制开关5配合的通孔61，控制开关5伸出通孔61。该耐磨保护套6可采用硅胶保护套。
本实施例中，收线筒1的外侧轴向间隔设有环形挡板11，环形挡板11与收线筒1固定连接，充电线2缠绕于两个环形挡板11之间，通过环形挡板11限制充电线2缠绕于收线筒1上的位置，环形挡板11能避免收线筒1转动时，充电线2与其他不转动的物体之间发生摩擦，有利于充电线2长久使用。
实施例二：一种具有收放线装置的充电桩，包括充电桩壳体7和收放线装置，充电桩壳体7的侧壁上设置有安装口71，收放线装置包括收线筒1、充电线2以及充电枪3，充电线2一端与供电设备连接，充电线2的中间部分缠绕在收线筒1的外侧壁上，充电线2的另一端与充电枪3固定连接，收线筒1和充电线2设置在充电桩壳体7内，充电枪3插装在安装口71处。
该具有收放线装置的充电桩还包括具有驱动轴41的电机4和用于控制电机4运转或关闭的控制开关5，驱动轴41与收线筒1固定连接，驱动轴41与收线筒1同轴，电机4通过驱动轴41驱使收线筒1转动 收线，控制开关5固定设置在充电枪3上。
本实施例中，充电枪3的外侧壁上套设有耐磨保护套6，耐磨保护套6上开设有与控制开关5配合的通孔61，控制开关5伸出通孔61。
实施例三：其余部分与实施例二相同，其不同之处在于安装口71处设置有环形橡胶圈72，安装口71的边沿与环形橡胶圈72的外圈连接，环形橡胶圈72的内圈开口大小与充电枪3的尾部相适配，充电枪3上设有环形垫片31，环形垫片31的外直径大于环形橡胶圈72的内圈开口直径而无法穿过环形橡胶圈72，并且在充电线2完全被收回时，环形橡胶圈72被环形垫片31作用形成肉眼易识别的凹陷锥形结构。
实施例四：其余部分与实施例二相同，其不同之处在于充电桩壳体7内设置有用于限制充电线2收线和放线的运动轨迹的定位导向装置8。
本实施例中，定位导向装置8包括固定设置在充电桩壳体7的内侧壁上的第一支架81和可转动的设置在第一支架81上的第一定滑轮82，充电线2经第一定滑轮82后与充电枪3固定连接。
实施例五：其余部分与实施例四相同，其不同之处在于定位导向装置8还包括固定设置在充电桩壳体7的内侧壁上的第二支架83和可转动的设置在第二支架83上的第二定滑轮84，第二定滑轮84和第一定滑轮82之间形成供充电线2穿过的间隙。
本实施例中，控制开关5包括开启按钮51、关闭按钮52、用于控制电机4关闭的接近开关53和与接近开关53适配的检测块54，开启按钮51和关闭按钮52分别固定设置在充电枪3上，接近开关53固定设置在充电桩壳体7的内侧壁上，检测块54固定设置在充电线2上；当检测块54跟随充电线2移动进入到接近开关53的检测范围内时，接近开关53断开，按压的开启按钮51无法使电机4运转，当检测块54跟随充电线2移动离开接近开关53的检测范围时，接近开关53闭合，按压的开启按钮51能够使电机4运转。
本实施例中，检测块54位于第一定滑轮82与安装口71之间的充 电线2上，检测块54在跟随充电线2移动的过程中不会与第一定滑轮82或第二定滑轮84发生接触，从而避免发生碰撞。
本实施例中，接近开关53可采用电感式传感器，相应的检测块54采用环形的金属块。
以上实施例公开的具有收放线装置的充电桩的简要工作过程如下：
充电桩放线进行充电时，用户通过充电枪3拉动充电线2，充电线2带动收线筒1正转，根据实际需要拉出相应长度的充电线2使用即可。若拉出的充电线2过长时，可先通过按压开启按钮51使电机4反转进行收线，然后通过按压关闭按钮52使电机4停止，从而调节充电线2拉出的长度。
充完电需要收线时，用户可将充电枪3放置在地上并按压开启按钮51，此时电机4反转进行收线，收线过程中检测块54跟随充电线2移动并靠近接近开关53，接近开关53检测到检测块54并断开，电机4停止运转，此时充电枪3已经插装在安装口71处，即完成收线动作。
当然，以上只是本实用新型的典型实例，除此之外，本实用新型还可以有其它多种具体实施方式，凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求保护的范围之内。
