Description

带防护功能的电动车制动手柄 技术领域
本实用新型属于制动器技术领域，涉及一种制动手柄，特别涉及带防护功能的电动车制动手柄。
 背景技术
制动手柄在蝶式刹车中主要用于控制制动盘两侧蹄片相对运动实现与制动盘之间相互夹紧，其连接方式主要有钢索连接或者液压传动，其中钢索式的连接结构具有制造简单成本低的优点，现有技术中，钢索的端部通常是直接卡在柄体上，容易将钢索皮套磨破，并且直接卡入式结构钢索端部通常直接位于柄体外，其卡紧处容易被外物堵住造成制动异常或者钢索断裂。
 技术问题
本实用新型的目的是针对现有技术中存在的上述问题，提供了一种将钢索的连接位置和连接结构进行改进，并增加防护罩起到保护连接处防止被异物卡死的制动手柄。
 技术解决方案
本实用新型的目的可通过下列技术方案来实现：带防护功能的电动车制动手柄，包括柄体、固定座和钢索，所述的柄体铰接于固定座上与钢索连接，其特征在于，所述固定座的内部设置有连接座，所述的连接座呈U型且底面具有开口，所述的连接座与柄体之间设置有连杆，所述连杆的一端穿过开口与连接座铰接另一端与柄体铰接，所述连接座的端部垂直向外折弯形成挡板结构且在挡板结构的中心开设有连接孔，所述的钢索穿过连接孔并在后方固定，所述固定座的顶部通过柱销铰接有盖板。
在上述带防护功能的电动车制动手柄中，所述的盖板呈包裹式结构即盖板的两侧内壁与固定座的两侧外壁间隙配合。
在上述带防护功能的电动车制动手柄中，所述的固定座上位于钢索的上下两端开设有卡槽，所述固定座的侧方位于盖板内设置有挡板，所述的挡板卡入卡槽内，所述的挡板通过螺丝与固定座进一步固定。
在上述带防护功能的电动车制动手柄中，所述固定座的内部设置有密封套，所述的钢索穿过该密封套使接触面形成密封。
本制动手柄将传统的柄体与钢索的直连接结构改进为在两者之间设置连接座和连杆，使钢索与连接座固定，连杆两端与柄体连接座铰接，因此在制动时连接座会与固定座内部形成限位使其可以拉动钢索直线运动，钢索活动时不会与外部接触不易磨损，也使得制动稳定性更好，并且在固定座上方增加盖板，外部杂物不易进入固定座内影响制动，进一步的，盖板为可开合式结构，便于手柄的整体装配，也方便后期在固定座内部各个配合面添加润滑油。
 有益效果
与现有技术相比，本制动手柄主要通过将传统钢索的直连式改进成铰接式并配合开合式的盖板使其具有制动更加稳定，防护性更好也便于后期维护的优点。

 本发明的最佳实施方式
以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。
如图1至图3所示，本带防护功能的电动车制动手柄，包括柄体1、固定座2和钢索3，柄体1铰接于固定座2上与钢索3连接，固定座2的内部设置有连接座4，连接座4呈U型且底面具有开口，连接座4与柄体1之间设置有连杆5，连杆5的一端穿过开口与连接座4铰接另一端与柄体1铰接，连接座4的端部垂直向外折弯形成挡板9结构且在挡板9结构的中心开设有连接孔4a，钢索3穿过连接孔4a并在后方固定，固定座2的顶部通过柱销6铰接有盖板7。
进一步说明，盖板7呈包裹式结构即盖板7的两侧内壁与固定座2的两侧外壁间隙配合，该结构的设计使固定座2的两侧具有防水效果，水流不易从端面进入固定座2内。
其中，固定座2上位于钢索3的上下两端开设有卡槽8，固定座2的侧方位于盖板7内设置有挡板9，挡板9卡入卡槽8内，挡板9通过螺丝与固定座2进一步固定，固定座2的侧面通过设置挡板9使其便于制造时的内部装配，组装更加便捷。
固定座2的内部设置有密封套10，钢索3穿过该密封套10使接触面形成密封，由于下雨时水流容易顺着钢索3流动，通过设置密封套10可以防止水流进入固定座2内使内部生锈。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了各种术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本实用新型的本质；把它们解释成任何一种附加的限制都是与本实用新型精神相违背的落。
