Description

一种驾驶座椅摆动支撑机构 技术领域
本发明属于轨道车辆座椅制造技术领域，尤其涉及一种驾驶座椅摆动支撑机构。
背景技术
轨道车辆驾驶室中座椅的重要作用是确保司机操作驾驶台的所有正常驾驶功能设备。为满足舒适驾驶的要求，轨道车辆驾驶室中的司机座椅一般具有高度调节、前后调节、旋转调节、靠背倾斜调节等功能，确保司机处于生理学角度的正确姿势，符合人机工程学和健康等方面的需求。同时，在满足驾驶舒适度的要求下，还是要兼顾驾驶的安全性，比如欧洲要求司机座椅与驾驶台的净间距应达到半米以上，才能符合司机在站立位置操作驾驶时安全驾驶的要求。现有的调节座椅与驾驶台净间距的前后调节是通过设置在座椅底部的滑动装置实现的，驾驶员实现坐姿与站姿的切换只能通过手动控制滑动装置实现缓慢调节，净间距调整不到位，将影响驾驶员站立驾驶的安全。此外，在紧急情况下，座椅将会是司机逃离的障碍物。故急需一种能够使驾驶座椅的坐姿位置和站姿位置迅速切换的机构，允许对驾驶座椅与驾驶台的净间距进行调整，从而获得站立驾驶位置所需的必要自由空间，以保证站姿操作时的驾驶安全。
发明内容
本发明目的在于提供一种驾驶座椅摆动支撑机构,其在保证舒适性的前提下，能够解决坐姿和站姿无法迅速切换，导致驾驶座椅与驾驶台的净间距无法达到规定标准，不能够有效保障安全驾驶的技术问题。
为解决上述技术问题，本发明所采用的具体技术方案如下：
一种驾驶座椅摆动支撑机构，用于支撑座椅本体以及设置在座椅本体底 部的滑动装置，其包括底板和顶板，所述顶板用于安装所述座椅本体和所述滑动装置，所述顶板与底板之间设有前后平行布置的两个支架，各所述支架的上下两端分别铰接于所述顶板及所述底板，以使所述顶板可前后摆动；
还包括前限位梁、后限位梁，所述前限位梁和后限位梁均固定在底板上且与所述支架对应设置，以使所述顶板具有前置位置和后置位置；当所述顶板位于前置位置时，位于前方的所述支架靠合于前限位梁，当所述顶板位于后置位置时，位于后方的所述支架靠合于后限位梁；
还包括锁止装置，所述锁止装置用于将所述顶板锁止在前置位置或/和后置位置。
上述技术方案，可直接安装在在现有轨道车辆驾驶座椅底部的滑动装置的下部，实现了驾驶座椅的前置位置和后置位置的迅速切换，达到了轨道车辆使用地对驾驶座椅相对于驾驶台净间距所规定的标准，保证了驾驶员站立驾驶的安全性。通过在顶板和底板之间铰接两个相互平行的支架，实现驾驶座椅的前后摆动，并在底板上固定设置前限位梁和后限位梁，保证了驾驶座椅在前置位置和后置位置的支撑稳定性。同时，设置锁止装置将驾驶座椅锁止在前置位置和/或后置位置，进一步有效地保证了驾驶的安全性。
优选的，所述锁止装置包括止挡件、设在支架下端的凸轮，所述止挡件的位置可以移动从而具有至少两个位置：锁止位、开放位，当所述止挡件位于锁止位时，所述止挡件与所述凸轮形成止挡配合。
优选的，所述锁止装置还包括连杆、弹簧；所述连杆包括第一段和第二段，所述第一段和第二段的连接部铰接于所述底板形成一杠杆结构，所述第二段与所述底板之间设置弹簧；所述止挡件设在所述第一段的自由端，当顶板位于前置位置或/和后置位置时，所述止挡件与所述凸轮形成止挡配合。通过铰接在底板上的连杆以及设置在连杆一端且与凸轮配合的止挡件将顶板锁止在前置位置和/或后置位置，该结构简单且能够有效锁止摆动支撑机构。
优选的，所述凸轮至少具有第一止挡面、第二止挡面，所述止挡件通过与所述第一止挡面或所述第二止挡面靠合进行限位。
进一步，所述底板上设有立板，所述立板上沿竖直方向设有长条形的槽孔，所述止挡件通过穿接在所述槽孔中上下移动，当所述顶板位于前置位置或后置位置时，所述止挡件位于槽孔的下端的锁止位。开设在立板上的槽孔限定了止挡件的运动轨迹，并且保证了锁止装置对摆动支撑机构的有效锁止。
进一步，还包括踏板，所述踏板的两端分别与两个所述连杆的第二段的自由端相连接。踏板供驾驶员踩踏以实现前置位置和后置位置的切换。
进一步，所述摆动支撑机构还包括气弹簧，所述气弹簧的两端分别与所述顶板和所述底板连接。在前置位置和后置位置切换时，气弹簧确保了摆动支撑机构运动无卡滞且可靠切换。
进一步，所述气弹簧的顶端位于靠近后置位置的一侧，所述气弹簧的底端位于靠近前置位置的一侧。在从前置位置切换到后置位置过程中，气弹簧伸张力的辅助作用减小了切换所需施加的外力，便于操作。
优选的，所述弹簧为扭力弹簧或压缩弹簧，扭力弹簧和压缩弹簧的形变次数至少可达到几十万次，使用寿命长，使用过程中，利用弹簧所产生的的弹力或扭力，使得止挡件和凸轮能够有效贴合，进而将驾驶座椅锁止在所需位置。
本发明具有以下优点：
1、本发明直接安装在设置于驾驶座椅下的滑动装置的下部，即可实现驾驶座椅的前置状态和后置状态的迅速切换，确保满足对驾驶座椅相对于驾驶台净间距的规定，保证驾驶员站立驾驶的安全性；此外，该摆动支撑机构能够实现对驾驶座椅的稳固支撑和限位，并通过结构简单的锁止装置便可将摆动支撑机构锁止在前置位置和/或后置位置，驾驶安全性有保障。
2、本发明还设有沿摆动方向倾斜的气弹簧，使得摆动支撑机构运动顺畅且切换可靠。同时，气弹簧向摆动支撑机构的后置位置倾斜，发挥气弹簧伸张力的作用，减小位置切换所需时间的外力，操作方便。
3、本发明能够与现有驾驶座椅结构等相适应，满足对驾驶舒适度的要求，同时摆动支撑机构结构简单，安全稳定性优良，能够保证驾驶员对驾驶安全以及紧急安全逃生的需求。

具体实施方式
为了更好地了解本发明的目的、结构及功能，下面结合附图，对本发明一种驾驶座椅摆动支撑机构做进一步详细的描述。
如图1、图2所示，该实施例的摆动支撑机构设置在座椅本体1底部的滑动装置2的下部，用于支撑座椅本体1和滑动装置2，所述摆动支撑机构 使得驾驶座椅具有前置位置和后置位置。该实施例能够与现有轨道车辆驾驶座椅及其关联结构相适应，满足驾驶员对舒适度的要求，同时实现驾驶座椅在前置位置和后置位置的迅速切换，使得驾驶座椅相对于驾驶台的净间距满足规定标准，进而保证驾驶员站立驾驶的安全性。
如图1-4所示，所述摆动支撑机构包括顶板4和底板3，在所述顶板4与底板3之间平行设置两个支架5，各支架5的上下两端分别与所述顶板4和所述底板3铰接在一起，使得顶板4可前后摆动。其中，靠近前置位置的支架5的前侧设有前限位梁6，当所述顶板4位于前置位置时，靠近前置位置的支架5靠合于前限位梁6，并通过锁止装置8锁止在前置位置，以形成安全稳定支撑，上方载荷通过靠近前置位置的支架5传递给前限位梁6承受；靠近后置位置的支架5的后侧设有后限位梁7，当所述顶板4位于后置位置时，靠近后置位置的支架5靠合于后限位梁7，并通过锁止装置8锁止在后置位置，以形成安全稳定支撑，上方载荷通过靠近后置位置的支架5传递给后限位梁7承受。需要说明的是，前限位梁6和后限位梁7的位置可以根据结构需要进行调整，同样可达到限位支撑的效果，实现发明目的。所述前限位梁6和后限位梁7上均设有与支架5贴合的斜面，实现支架5与限位梁的面接触，避免应力集中。
如图3-5所示，所述锁止装置8包括两组由一连杆81、一扭簧以及与靠近后置位置的支架5下端固定连接的凸轮83组成的止挡结构。所述连杆81包括第一段811和第二段812，所述第一段811和第二段812的连接部813铰接于底板3上，形成一杠杆结构。所述第一段811的自由端设有止挡件814，当顶板4位于前置位置时，所述止挡件814与所述凸轮83上的第一止挡面83a贴合,形成止挡配合，保证支撑的安全性和稳定性；当顶板4位于后置位置时，所述止挡件814与所述凸轮83上的第二止挡面83b贴合,形成止挡配合，保证支撑的安全性和稳定性。两个连杆81的第二段812的自由端分别与 踏板12的左右两端连接，踏板12供驾驶员踩踏以实现前置位置和后置位置的切换。为保证摆动支撑机构的有效锁止，在底板3上设置垂直于底板3的立板10，并在立板10上开设在竖直方向上具有一定长度的槽孔11，限定了止挡件814的运动轨迹，所述止挡件814穿接在槽孔11中。当所述顶板4位于前置位置和后置位置时，所述止挡件814位于槽孔11的下端。所述第二段812与所述底板3之间设有一扭簧，为前述杠杆结构提供弹力，使得止挡件814与凸轮83形成有效止挡配合。所示扭簧可替换为压缩弹簧，同样能够达到相应效果，实现发明目的。需要说明的是，锁止装置8所包含零部件的数量以及相关零部件的布置位置可根据需要调整，例如，可将凸轮83固定在靠近前置位置的支架5下端，同时调整连杆81的布置形式，同样能够达到止挡限位的效果。
如图1-4所示，在所述底板3与所述顶板4之间设有气弹簧9，所述气弹簧9沿摆动方向倾斜布置，在前置位置和后置位置切换时，气弹簧9确保了摆动支撑机构运动无卡滞且切换可靠。为了减小向后置位置切换所需外力，便于驾驶员操作及紧急逃生，所述气弹簧9的顶端位于靠近后置位置的一侧，即所述气弹簧9向后置位置方向倾斜。
本发明的工作过程是：
当驾驶员需求坐姿操作时，弹簧(82)处于伸张状态，踏板(12)通过锁止装置8的杠杆结构将力传递给止挡件(814)，使止挡件(814)保持在槽孔(11)中的锁止位(即最低位置)，止挡件(814)与凸轮(83)接触限位，此时凸轮(83)的第一止挡面(83a)靠合于止挡件(814)上。位于前方的支架(5)与前限位梁(6)平行接触进行承重，驾驶座椅摆动支撑机构保持在前置状态。除非操作踏板(12)，否则无法改变座椅摆动支撑机构的状态。
当驾驶员需求站姿操作时，需求更大的后方区域空间，可以将座椅底座 机构设置为后置状态，具体操作如下：驾驶员使用脚压住踏板(12)至其最低位置，弹簧(82)处于压缩状态，踏板(12)通过锁止装置8的杠杆结构将力传递给止挡件(814)，使止挡件(814)保持在槽孔(11)中的开放位(即最高位置)，此时止挡件(814)与凸轮(83)无接触限位；驾驶员同时用手将座椅向后推动，气弹簧(9)伸张将位于后方的支架(5)移动到与后限位梁(7)平行接触；驾驶员再松开踏板(12)，弹簧(82)处于伸张状态，踏板(12)通过锁止装置8的杠杆结构将力传递给止挡件(814)，使止挡件(814)移动至槽孔(11)中的锁止位(即最低位置)，止挡件(814)与凸轮(83)接触限位，此时凸轮(83)的第二止挡面(83b)靠合于止挡件(814)上，位于后方的支架(5)与后限位梁(7)通过平行接触面进行承重。驾驶座椅摆动支撑机构保持在后置状态。除非操作踏板(12)，否则无法改变座椅摆动支撑机构的状态。
当驾驶员需求从站姿操作切换到坐姿操作时，驾驶员使用脚压住踏板(12)至其最低位置，同时用手将座椅向前推动，气弹簧(9)压缩，直至位于前方的支架(5)移动到与前限位梁(6)平行接触，驾驶员再松开踏板(12)，弹簧(82)处于伸张状态，踏板(12)通过杠杆结构将力传递给止挡件(814)，使止挡件(814)保持在槽孔(11)中的锁止位(即最低位置)，止挡件(814)与凸轮(83)接触限位，位于前方的支架(5)与前限位梁(6)平行接触进行承重。
可以理解，本发明是通过实施例进行描述的，本领域技术人员知悉的，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明所保护的范围内。
