Description

一种滑动门门锁装置
本申请要求于 2008 年 6 月 30 日提交中国专利局、 申请号为 200810022271.1、 发明名称为"一种滑动门门锁装置 "的中国专利申请的优先 权， 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及车门门锁领域， 具体涉及一种滑动门门锁装置。 背景技术
目前在汽车的滑动门上，车身钣金结构留给门锁控制机构和门把手的布置 空间并不充裕， 因此采用现有的常规布置很难达到令人满意的效果。 如图 1 所示， 外开把手 10通过转换器 20A与滑动门控制机构连接， 而转换器 20A通 常含有两个甚至更多个转换件， 因此转换器 20A在车门中沿车体外侧至车体 内侧方向需要占用很大的空间， 由此导致了锁体布置的难度加大， 同时也增加 了产品的复杂性和成本。
发明内容
本发明的目的是提供一种滑动门门锁装置， 其结构筒单且便于安装。
为实现上述目的， 本发明采用了以下技术方案： 一种滑动门门锁装置， 包 括固定在滑动门外侧面上的外开把手，外开把手通过拉索与设置在滑动门内部 的门锁转换机构相连， 门锁转换机构通过开锁拉杆 /拉线与锁体相连， 外开把 手依次通过拉索、 门锁转换机构及开锁拉杆 /拉线开启锁体。
由上述技术方案可知， 本发明在外开把手和门锁转换机构之间设置有拉 索， 由于拉索为线状部件， 因此其在车门中占据的空间较小， 从而大大减小了 锁体的布置难度。 由上述可知， 本发明结构筒单， 便于安装且成本较低。

具体实施方式
如图 2、 图 12所示， 一种滑动门门锁装置， 包括固定在滑动门外侧面上 的外开把手 10, 外开把手 10通过拉索 20与设置在滑动门内部的门锁转换机 构相连， 门锁转换机构通过开锁拉杆 /拉线 30与锁体 70相连， 外开把手 10依 次通过拉索 20、 门锁转换机构及开锁拉杆 /拉线 30开启锁体 70。
由上述可知， 拉索 20的设置使得本发明可以在车门这样有限的空间中对 外开把手 10和门锁转换结构进行更合理地布置， 因此筒化了结构且降低了成 本。
作为本发明的优选方案， 如图 2所示， 所述的外开把手 10位于滑动门内 部的一侧设有沿水平方向延伸的悬臂 11 , 拉索 20的一端固定在悬臂 11上， 另一端与设置在支架 90上的门锁转换机构相连，拉索 20的受力方向与其在悬 臂 11上的固定端相垂直， 支架 90固定在滑动门内部。
由于在本发明中采用拉索 20进行力的传递，且拉索 20所受力的方向始终 垂直于拉索 20在悬臂 11上的固定端， 因此减少了开启时力的浪费，使滑动门 的开启较为容易。
如图 2、 图 3、 图 4、 图 5、 图 6、 图 7所示， 所述的门锁转换机构包括绕 销轴 91独立转动的外开转换件 40和锁体转换件 60, 销轴 91设置在支架 90 上， 外开转换件 40的一端设有第一悬臂 41 , 第一悬臂 41上设有定位槽， 拉 索 20与门锁转换机构相连的一端卡接在定位槽上，复位弹簧 45—端固定在支 架 90上， 另一端与外开转换件 40相连并使其复位， 锁体转换件 60通过水平 向设置的开锁拉杆 /拉线 30与锁体 70相连，外开把手 10依次通过拉索 20、外 开转换件 40、 锁体转换件 60以及开锁拉杆 /拉线 30开启锁体 70。
上述设置方式使开启力沿外开转换件 40和锁体转换件 60逐次传递，最后 通过锁体转换件 60上的开锁拉杆 /拉线 30开启锁体 70, 力的开启路线较为筒 捷且损耗较小。
作为本发明进一步的优选方案， 所述的销轴 91呈水平状且与车长方向相 垂直， 拉索 20的拉力方向位于销轴 91转动的切线方向。
所述的车长方向， 也即自车头至车尾的纵向方向， 销轴 91的上述设置方 式使得现有的外开把手 10的开启方向与拉索 20中力的方向相垂直，进一步减 省了用力； 而拉索 20的拉力方向位于销轴 91转动的切线方向， 则保证了拉索
20转动外开转换件 40的用力较省， 上述两种方式的结合则使得使用外开把手
10开启滑动门时， 手感舒适且开启力度较小。
如图 4、 图 8、 图 9、 图 10、 图 11所示， 所述的门锁转换机构还包括与外 开转换件 40和锁体转换件 60同轴设置的内开转换件 50, 内开转换件 50与内 开把手相连， 复位弹簧 53—端固定在支架 90上， 另一端与内开转换件 50相 连并使其复位， 内开把手依次通过内开转换件 50、 锁体转换件 60以及开锁拉 杆 /拉线 30开启锁体 70。
上述设置方式使开启力沿内开转换件 50和锁体转换件 60逐次传递，最后 通过锁体转换件 60上的开锁拉杆 /拉线 30开启锁体 70, 因此内开开启力的开 启路线同样较为筒捷且损耗较小。
如图 2 ~ 11所示，所述的销轴 91依次穿过内开转换件 50、外开转换件 40、 锁体转换件 60以及支架 90本体， 内开转换件 50上设有两个悬臂， 第一悬臂 51与外开转换件 40上的第二悬臂 42为贴靠配合， 并使内开转换件 50可带动 外开转向件 40同向转动，内开转换件 50的第二悬臂 52与支架 90上的限位孔
92构成限位配合； 外开转换件 40上的第三悬臂 43与锁体转换件 60上的第二悬臂 62为贴靠 配合， 并使外开转换件 40可带动锁体转换件 60转动复位， 支架 90上设置有 供外开转换件 40的第四悬臂 44转动后复位到原位的限位挡块， 外开转换件 40的第四悬臂 44与复位弹簧 45相连；
锁体转换件 60上的第一悬臂 61与开锁拉杆 /拉线 30为铰接，第三悬臂 63 与支架 90上的限制其行程的挡块构成贴靠配合；
内开转换件 50上的第二悬臂 52的限位行程使开锁拉杆 /拉线 30的运动行 程可以开启锁体 70。
如上所述， 前述方式使得内开转换件 50、 外开转换件 40以及锁体转换件 60相互整合在一起， 人们不仅可以方便地从车体外部开启车门， 也可以方便 地从车体内部开启车门， 而且开启过程中力的传递路线均较为筒捷， 整个门锁 装置构造筒单且易于实现。
所述的门锁转换机构的旁侧设有使锁体转换件 60处于锁定状态和自由状 态的锁止机构 80。
由于设置了锁止机构 80, 因此车门不会在意外情况下被打开， 从而保护 了车内外的人员不受伤害。
作为本发明的优选方案， 如图 8、 图 9、 图 10、 图 11所示， 所述的锁止 机构 80由曲柄 82和与支架 90相铰接的摇臂 81构成， 曲柄 82的一端与摇臂 81铰接， 另一端为设置在滑槽 64中的滑块， 滑槽 64设置在锁体转换件 60的 第三悬臂 63上， 滑槽 64的两端部分别处在外开转换件 40的转动轨迹的内侧 和外侧， 滑块沿滑槽 64移动至外开转换件 40的转动轨迹的内侧时， 滑块与外 开转换件 40构成顶靠配合， 摇臂 81的一端设有挡块 811 , 挡块 811限位在支 架 90上的开孔中，挡块 811的限位行程使滑块可以自滑槽 64的一端滑至另一 端。
由于前述中人们无论从车体的内侧还是外侧开启滑动门时，力的传递均需 经过外开转换件 40, 因此本发明将曲柄 82端头上的滑块设置为与外开转换件 40构成顶靠配合， 由此限制了外开转换件 40的转动， 从而中断了力的传递， 使滑动门锁处于锁定状态。
作为本发明进一步的优选方案， 同样如图 8、 图 9、 图 10、 图 11所示， 所述的滑块与曲柄 82的柄身之间设置有凹部， 外开转换件 40的第四悬臂 44 顶靠在所述的 EJ部处，并使得外开转换件 40可带动锁体转换件 60转动并开锁。
所述的摇臂 81上还设有与电动或手动锁死机构的拉杆相连的开孔 83。 下面结合图 8、 图 9、 图 10、 图 11对本发明的动作过程作出如下说明： 如图 8所示， 当处在锁定状态时， 曲柄 82端头的滑块处在外开转换件 40 的转动轨迹的外侧， 此时扳动外开把手 10, 悬臂 11 带动拉索 20, 进而拉索 20带动外开转换件 40的第一悬臂 41转动， 外开转换件 40同时绕销轴 91转 动，外开转换件 40的第四悬臂 44无阻碍地滑过锁体转换件 60的第三悬臂 63 , 如图 9所示，由于此转动过程中外开转换件 40与锁体转换件 60不发生任何干 涉， 因此锁体转换件 60不动作， 锁体 70没有打开； 此时若松开外开把手 10, 则在复位弹簧 45的作用下， 外开转换件 40的第四悬臂 44逆向转动， 带动外 开转换件 40转动并在限位挡块的作用下复位到初始位置。
当扳动内开把手时， 内开转换件 50转动， 由于内开转换件 50的第一悬臂
51与外开转换件 40的第二悬臂 42相互为贴靠配合， 因此外开转换件 40跟随 转动， 其余动作过程参见前述。
解锁时， 电动或手动锁死机构动作， 通过开孔 83带动本发明的锁止机构 80动作， 摇臂 81在挡块 811限定的行程内动作， 同时驱动曲柄 82动作， 从 而使滑块沿滑槽 64移动至外开转换件 40的转动轨迹的内侧， 如图 10所示， 此时扳动外开把手 10, 则外开转换件 40的第四悬臂 44转动后与外开转换件 40构成顶靠配合， 如图 11所示， 在开启力的作用下， 外开转换件 40的第四 悬臂 44继续转动， 并通过曲柄 82端头的滑块带动锁体转换件 60的第三悬臂 转动， 丛而使锁体转换件 60的第一悬臂 61转动， 进而拉动开锁拉杆 /拉线 30 开启锁体 70; 此时若松开外开把手 10, 则在复位弹簧 45的作用下， 外开转换 件 40的第四悬臂 44逆向转动，同时外开转换件 40的第三悬臂 43带动锁体转 换件 60的第二悬臂 62动作， 使锁体转换件 60转动复位， 而外开转换件 40 也在限位挡块的作用下复位到初始位置。
解锁后扳动内开把手时， 内开转换件 50转动， 由于内开转换件 50的第一 悬臂 51与外开转换件 40的第二悬臂 42相互为贴靠配合， 因此外开转换件 40 跟随转动， 其余动作过程参见前述。
