Description

一种基于人机优化的驻车控制*** 技术领域
本发明涉及物流车领域，具体涉及一种基于人机优化的驻车控制***。
背景技术
驻车制动器是机动车辆安装的手动刹车(简称手刹)，在车辆停稳后用于稳定车辆，避免车辆在斜坡路面停车时由于溜车造成事故。
现有的手刹，如申请号为CN201320477005.4的专利，该专利公开了一种车辆及其驻车制动操纵装置，驻车制动操纵装置包括手刹操纵总成、与所述手刹操纵总成连接的前段驻车拉索、与前段驻车拉索连接的中段驻车拉索以及与中段驻车拉索连接的后段驻车拉索；还包括铰接于车架的杠杆，所述前段驻车拉索、所述中段驻车拉索分别与所述杠杆的两端连接。如此，手刹操纵总成拉动前段驻车拉索时，使与前段驻车拉索连接的杠杆一端向上运动，带动与中段驻车拉索连接的杠杆一端向前运动，形成杠杆和拉索的组合传动。
而若直接将该驻车制动操纵装置用于三轮车，则驻车制动操纵装置一般位于放脚的脚踏板上方，如申请号为CN200520010292.3的专利所示。由于驻车手刹总成位置问题，对于粗心的驾驶者或者新手驾驶者易出现下车未拉起制动杆的情况，这样往往会造成小型三轮物流车自行滑动，存在一定的危险，有改进的空间。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种基于人机优化的驻车控制***，可减少驾驶者忘记驻车的概率，提高了安全性。
为实现上述目的，本发明提供了如下技术方案：
一种基于人机优化的驻车控制***，包括把手组件和用于连接刹车***的拉索，所述把手组件靠近人体一侧设有手刹板，所述手刹板一端与把手部通过转轴旋转连接，所述拉索一端连接于手刹板中偏离转轴的位置处。
通过采用上述技术方案，本设计中驻车开关不同于传统的通过拉起脚边的制动杆启闭，而是采用了拉索在手刹板上的偏心旋转带动拉索移动；
而将开锁状态下的手刹板置于把手组件处，正好利用了把手组件处的空间，对驾驶者有提示的作用，因为把手组件的位置，正好是驾驶者插拔钥匙的地方，使手刹板容易被看到，从而减小了驾驶者下车后忘记驻车的概率。同时也节约了空间，使原来放置制动杆的位置可以空出来，提高了驾驶时的舒适性。
本发明的进一步设置为：所述把手组件呈Y型，所述把手部包括沿竖直设置的连杆部和连接于连杆部上端两侧的把手部，所述把手部靠近连接部一端安装有连接块，转轴安装于连接块，所述手刹板的转动轴向沿水平方向设置；当拉索处于开锁时，所述手刹板位于把手组件的上开口处。
通过采用上述技术方案，开锁状态下的手刹板置于Y形的上开口处，正好利用了把手组件中此处的空间，避免将手刹板突出在把手组件的外侧，避免了手刹板与驾驶员在开车时的碰撞，提高了安全性。
本发明的进一步设置为：当拉索处于闭锁时，手刹板远离转轴一端位于把手组件朝向人体一侧。
通过采用上述技术方案，手刹板可以通过旋转动作实现旋入或旋出Y形上开口；闭锁时将手刹板旋出Y形上开口，此时处于驻车状态，不需要再防止驾驶者不小心触碰到手刹板，反而为了避免驾驶员忘记复位手刹板而启动车体，需要将手刹板置于把手组件外侧这种较为醒目的位置，便于驾驶员发现手刹板；手刹板以旋入与旋出Y形上开口的动作，实现状态切换。
本发明的进一步设置为：手刹板包括连接于连接块的第一板和连接于第一板的第二板，所述手刹板呈L型，两个所述把手部之间设有覆盖连接块的壳体；当拉索处于开锁时，第二板贴合壳体的上表面，第一板贴合壳体的侧面。
通过采用上述技术方案，利用L形的直角与壳体的外表面贴合，使对手刹板处于开锁状态的限位，驾驶员直接将手刹板按在壳体上即为驻车机构的开锁位置，该设计有利于驾驶员快速的将手刹板置于开锁位置。
本发明的进一步设置为：壳体的上表面下凹形成的方便施力的缺口，缺口置于手刹板的下方。
通过采用上述技术方案，缺口的作用是让驾驶员手指伸入，便于驾驶员对手刹板施力，从而将手刹板翻转出Y形上开口。
本发明的进一步设置为：连接块的下表面设有挡块；当手刹板旋转拉动拉索实现闭锁时，挡块隔挡于手刹板以限制手刹板进一步转动。
通过采用上述技术方案，挡块的隔挡限位是为了控制手刹板闭锁时的位置，当手刹板旋转到挡块位置时将难以转动，也就到了手刹板的开锁位置。
本发明的进一步设置为：连接块内设有启动电线，启动电线上包括左右压合导通的弹性开关，挡块固定有朝向弹性开关压合处的绝缘片；连接块内设有供挡块滑向弹性开关的 滑道，且旋转手刹板实现推动绝缘片***弹性开关。
通过采用上述技术方案，启动电线是指：用于车体启动时用的通电线。驾驶员经常会出现下述的操作失误，往往忘记将驻车开关复位(也就是开锁)，就直接启动车体，由于车体处于锁死状态下启动对车体的伤害极大，会降低车体的使用寿命；
而本设计中采用绝缘片***的弹性开关的方式，使得启动电线断路，而且该断路方式是每次在驻车动作时通过手刹板带动的，故一旦驻车后，启动电线就断路；这样设计的效果很明显，若驾驶员在忘记复位手刹板下是无法启动车体的，也就避免了上述失误操作对车体的损伤。而需要启动车体时，把绝缘片沿滑道拔出弹性开关即可。
本发明的进一步设置为：挡块与手刹板之间设有拉绳，手刹板旋转至开锁时拉动拉绳以驱动绝缘片滑出弹性开关。
通过采用上述技术方案，拉绳第一个作用是：连接挡片与手刹板，挡片即使意外滑脱滑道也不会丢失；拉绳第二作用是：联动，当手刹板复位旋转至壳***置时，将拉动拉绳从而带动绝缘片拉出弹性开关，显然通过拉绳的联动，驾驶员无需去进行一步将绝缘片拔离弹性开关的步骤，使得整个操作更加的简洁。
本发明的进一步设置为：所述手刹板的转动轴向沿竖直方向设置，当拉索处于闭锁时，手刹贴合于把手组件外壁。
通过采用上述技术方案，驾驶者下车时，可顺势旋转手刹板以实现驻车制动，使用方便，从而减小了驾驶者下车后忘记驻车的概率。
本发明的进一步设置为：所述把手组件呈Y型，所述把手部包括沿竖直设置的连杆部和连接于连杆部上端两侧的把手部，所述把手部靠近连接部一端安装有安装座，所述手刹板垂直于地面，且所述手刹板于其铰接端凸出形成有互相平行且位于同一竖直线的第一安装块、第二安装块；所述安装座于其侧面凸出形成有与第一安装块和第二安装块配合并通过紧固件穿设连接的连接筒。
通过采用上述技术方案，手刹板通过第一安装块和第二安装块与连接筒在紧固件的穿设连接下实现手刹板的水平方向旋转；
紧固件的穿设连接，当驾驶者不对手刹板施加作用力时手刹板保持垂直于安装座的状态；当物流车停稳后驾驶者下车时，垂直于安装座的手刹板有利于提醒驾驶者顺势对手刹板施加一定的作用力进行水平方向的旋转以实现驻车制动。
本发明具有以下优点：1、可减少驾驶者忘记驻车的概率，提高了安全性；2、手刹板在旋转过程中控制驻车机构的启闭的同时，利用挡块与拉绳的联动同时控制的启动电线的 开闭，有效的避免了车体在驻车状态下车体启动的情况发生，一定程度上减少了车体损耗。

具体实施方式
实施例一：
如图1和图2所示，一种基于人机优化的驻车控制***，包括把手组件7，把手组件7包括 竖直的连杆部71，以及置于连杆部71上端呈对称设置的两个把手部72。连杆部71和两个把手部72整体呈Y形，并且两个把手部72形成Y形的上开口73。
如图2和图3所示，驻车控制***还包括，位于两把手部72之间的安装座1、铰接于安装座1靠近驾驶座位一侧面且可水平方向旋转的手刹板2、连接于小型三轮物流车制动器的拉索3、一端连接于拉索3另一端连接于手刹板2且受控于手刹板2并牵动拉索3的副拉索4。
如图2、图3、图4所示，在本实施例中手刹板2呈方形设置，且手刹板2垂直于地面。手刹板2于其铰接端凸出形成有互相平行且位于同一竖直线的第一安装块21、第二安装块22，第一安装块21和第二安装块22呈方形设置，且第一安装块21和第二安装块22远离手刹板2一端的拐角处均设置有倒圆角。安装座1于其侧面凸出形成有与第一安装块21和第二安装块22配合并通过紧固件6穿设连接的连接筒11，且紧固件6与开设于第一安装块21和第二安装块22上的通孔过盈配合。当对手刹板2水平方向顺时针或者逆时针进行旋转时，紧固件6与第一安装块21和第二安装块22同步转动，紧固件6与连接筒11相对转动。
如图4、图5所示，手刹板2还凸出形成有平行于第二安装块22的第三连接块23，第三连接块23呈方形设置，且第三连接块23远离手刹板2一端的拐角处均设置有倒圆角。副拉索4(参考图3)连接有一端与第三连接块23抵接、另一端与第二安装块22抵接的连接轴41，连接轴41用塑料制成，且连接轴41的横向截面呈圆形设置。第三连接块23上开设有供连接轴41下端部***的连接孔231，连接孔231内侧壁凸出形成有若干卡齿2311，连接轴41下端部形成有若干与卡齿2311配合的卡槽411。
如图4、图5所示，第一安装块21的厚度小于第二安装块22的厚度，第二安装块22与连接轴41上端部抵接处开设有供连接轴41上端部放置的放置槽221，放置槽221内侧壁凸出形成有若干卡齿2311，连接轴41上端部形成有若干与卡齿2311配合的卡槽411。当对手刹板2水平方向顺时针或者逆时针旋转90度时，手刹板2以连接筒11为旋转中心，连接轴41与第二安装块22和第三连接块23同步旋转90度，副拉索4(参考图3)在连接轴41旋转的同时绕连接轴41外侧面缠绕90度以使得副拉索4(参考图3)拉紧实现小型三轮物流车的驻车制动。
如图5所示，第三连接块23于其侧边还开设有便于安装连接轴41的开启口232。且连接轴41的侧面周向凸出形成有用于增加连接轴41中心处直径大小的缠绕部412，连接轴41中心处缠绕部412的设置，使得连接轴41与第一安装块21和第二安装块22同步转动时 增大副拉索4(参考图3)缠绕的长度，以确保小型三轮物流车的驻车制动到位。
如图5、图6所示，安装座1于手刹板2的两侧均开设有呈长方形设置的滑移腔12。安装座1于手刹板2两侧均安装有用于锁定手刹板2的锁定组件5，锁定组件5(图中未标出)包括滑移安装于滑移腔12的竖向滑移板52、凸出形成于竖向滑移板52底端侧面的锁扣51、安装于滑移腔12位于锁扣51处辅助竖向滑移板52复位滑移的压簧53；手刹板2上开设有与锁扣51配合锁定的锁定孔24。
如图6所示，压簧53的一端与滑移腔12短边侧面抵接，压簧53的另一端与竖向滑移板52短边侧面抵接；压簧53垂直于滑移腔12的短边侧面，且垂直抵接于竖向滑移板52的短边侧面中心处，以确保竖向滑移板52在复位时受力均衡；且滑移腔12的短边侧面还凸出形成有供压簧53套设的平衡柱121，平衡柱121的设置避免压簧53竖向压缩或者竖向复位时发生倾斜、甚至从竖向设置变为横向设置以无法完成竖向滑移板52复位的问题。
如图5、图7所示，竖向滑移板52底端侧面凸出形成有两个锁扣51，且两个锁扣51呈“L”形设置，两个锁扣51弯折部的外侧面均设置有引导面。锁定孔24呈长方形设置，锁定孔24中心处凸出形成平行于锁定孔24长边方向的隔板241，隔板241将锁定孔24分隔为第一锁孔242和第二锁孔243。第一锁孔242上侧面靠近隔板241的一端开设有供两锁扣51弯折部卡扣的第一卡扣槽244，第二锁孔243上侧面靠近隔板241的一端开设有供两锁扣51弯折部卡扣的第二卡扣槽245。
以驾驶员坐于驾驶座方向为参考方向，当手刹板2水平方向顺时针旋转90度时，两锁扣51弯折部扣于第一卡扣槽244；当手刹板2水平方向逆时针旋转90度时，两锁扣51弯折部扣于第二卡扣槽245。
如图6、图7所示，竖向滑移板52远离锁扣51的一端凸出形成有施力块521。滑移腔12中螺纹设置有用于盖合竖向滑移板52的垫片122，竖向滑移板52远离锁扣51的一端开设有与螺栓滑移连接且平行于竖向滑移板52的长腰型槽522。
工作过程：
1、若驾驶员预从驾驶座左边离开时可用右手将手刹板2顺时针旋转90度且可用左手对施力块521施加向下的作用力，使得两锁扣51弯折部扣于第一卡扣槽244，实现驻车制动；若驾驶员预从驾驶座右边离开时可用左手将手刹板2逆时针旋转90度且可用右手对施力块521施加向下的作用力，使得两锁扣51弯折部扣于第二卡扣槽245，实现驻车制动；
2、当驾驶员预启动小型三轮物流车，可用左手或者右手施加向下的作用力使得两锁扣51弯折部脱离于隔板241使得手刹板2旋转90度恢复至垂直于安装座1。
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
实施例二：
实施例二和实施例一的区别在于，如图8所示，连杆部71的上端连接有一个连接块74，两个把手部72分别***连接块74的左右两侧，并连接块74上通过盖板76将两个把手部72夹持固定，盖板76通过螺钉固定在连接块74上，故以此连接方式，实现连杆部71和两个把手部72的三者固定。
连接块74朝驾驶员操作方向设有凸块，凸块上旋转连接有手刹板2。
手刹板2整体呈L形，手刹板2包括连接于连接块74的第一板25和连接于第一板25的第二板26。第二板26设有两个耳板27，两个耳板27的空隙处正好***凸块，而有一个转轴75同时穿过凸块与耳板27，使得手刹板2绕着转轴75可以进行竖直方向的转动，转轴75的两端通过卡簧固定使得耳板27与连接块74难以自由分离。
当手刹板2进行绕转轴75旋转时，手刹板2可以转入到上开口73位置，利用上开口73处的腾出空间。而在手刹板2上连接有拉索3，拉索3的连接端相对转轴75偏离形成间距，由于该间距的存在，当手刹板2旋转时，拉索3发生拉伸或回缩的动作。
如图8与图9所示，当手刹板2旋转出上开口73位置，第一板25水平朝向驾驶员方向，此时驻车机构处于闭锁状态，车体难以移动，该工位时，手刹板2置于比较显眼的位置，是为了提醒驾驶员开车前需将驻车机构部解锁；连接块74的下表面固定有挡块78，当手刹板2拉动拉索3处于闭锁状态时，将手刹板2抵触在挡块78，由于挡块78的隔挡作用，第一板25将保持在水平位置。
当手刹板2旋入到连接块74上端时，也就是手刹板2旋入上开口73位置，此时驻车机构部处于开锁状态，车体可以自行启动；
连接块74上安装有如图10中的壳体77。
如图9与图10所示，壳体77通过螺钉与把手组件7进行固定；壳体77的上表面平整，壳体77临近转轴75的侧面竖直布置；当手刹板2处于开锁状态时，第一板25贴合壳体77的上表面，手刹板2的短片贴合壳体77的侧面。壳体77的上表面下凹形成一个缺口771；缺口771置于壳体77的边沿位置，并且手刹板2的一端置于缺口771的正上方，该设计的用意十分明显，使得驾驶员的手指可以沿着缺口771向手刹板2施力，使得驾驶员翻转手刹板22更加的便捷。
工作原理，当车体启动时，将手刹板2旋入到上开口73，此时拉索3处于回缩状态，驻车机构为开锁；手刹板2置于上开口73内，避免了手刹板2与驾驶员的接触；
当车体驻车时，将手刹板2旋出上开口73并水平摆放，此时，拉索3被拉伸，驻车机构为闭锁状态，此时车体难以移动。
实施例三：
实施例三与实施例二的不同之处，如图11所示，手刹板2的外壁与挡块78之间固定有拉绳82，而挡块78可以朝与转轴75的方向进行来回移动。
如图12与图13所示，在连接块74的凸块内开设有滑道81，挡块78的上端固定有长条形的绝缘片8，绝缘片8在滑道81内部移动，而挡块78在滑道81下方移动；而在滑道81内壁开设有内凹的滑槽91，在绝缘片8上固定有沿滑槽91滑移的滑块92；由于滑槽91与滑槽91内壁的竖向隔挡关系，绝缘片8不会从滑道81上直接竖向滑脱。故在挡块78的来回带动下，绝缘片8可以在滑道81内自由移动。
在滑道81的侧壁上开设有圆形孔，圆形孔内放置有启动电线83，启动电线83在滑道81位置截断，并且截断位置的两端都设有如下述相同的结构的弹性开关：
弹性开关为：启动电线83的端部固定有弹性件85，弹性件85为弹簧。圆形孔固定有插杆，插杆横向***弹簧将弹簧固定在圆形孔内，弹簧的另一端固定有金属片84；在弹簧的弹力作用，启动电线83截断位置处的两个金属片84相互贴合并且具有相向移动的运动趋势。
而当绝缘片8朝两个金属片84之间移动时，将会分开两个金属片84分开，从而实现启动电线83的断路。
工作原理阐述，当需要驻车时，手刹板22如图5中的顺时针旋转打开时，手刹板2的短边将抵触挡块78，此时挡块78在拨块的推动下朝两个金属片84方向移动，使得绝缘片8***到两个金属片84之间，实现启动电线83的断路，也就是在完成驻车动作的同时也完成了对车体的启动电源的断路。
而当需要开车时，将手刹板2逆时针旋转，此时拉绳82拉动推块移动，使得绝缘片8脱离两个金属片84之间，启动电线83实现通路，此时可以进行对车体的启动动作。而两个手刹板2上各自控制启动电线83一段的通路，该设计使得在车体未取消驻车前难以启动车体，减少车体损伤。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域 的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
