基于上述设计，本申请中伸缩组件30接收到控制器的指令后推动填隙板20穿过 箱体10开口伸出或缩回箱体10内，以使得填隙板20在列车进站时可填补列车与站台之间的空隙，使列车车厢与站台无缝连接，方便乘客进出，并可在列车未进站时给铁道留出较大空间，利于列车快速通过，避免列车与站台发生碰撞，且通过设置的锁定装置40可有效保证填隙板20伸出及缩回的固定效果，在其受到撞击或冲击时可即时实现缩回，即当填隙板20伸出或缩回时，锁定装置40中的伸缩固定梁41跟随填隙板20伸出或缩回，从而带动其上的伸出锁销板412及缩回锁销板411相对电磁锁43发生位移，同时加长轴芯组件430随着电磁锁43的锁舌434的伸出或缩回而从锁舌安装孔426中伸出或缩回，如图3所示，当伸出锁销板412卡接于与电磁锁43的锁舌434固定连接的加长轴芯组件430上，伸缩固定梁41伸出并固定稳定，伸缩固定梁41不会出现向内缩回的情况；如图4所示，当缩回锁销板411卡接于与电磁锁43的锁舌434固定连接的加长轴芯组件430上，伸缩固定梁41缩回并固定稳定，伸缩固定梁41不会出现向外伸出的情况。可理解地，当伸出锁销板412卡接于与加长轴芯组件430时，伸缩固定梁41向前伸出，此时若伸缩固定梁41受到撞击或冲击等，伸缩固定梁41会有向内移动的趋势，伸出锁销板412将撞击到加长轴芯组件430上，加长轴芯组件430受力后会将力转移至电磁锁固定件42上，如此，电磁锁43的锁舌434不会直接受到撞击或冲击的影响而遭受损坏，加长轴芯组件430有利于保护电磁锁43的锁舌434；而倘若撞击或冲击的力量大于与电磁锁固定件42连接的拉簧组件423的拉力时，加长轴芯组件430将该力转移给电磁锁固定件42后，电磁锁固定件42会克服拉簧组件423的拉力而相对转轴421发生远离伸缩固定梁41的旋转，电磁锁43随之旋转，此时，伸出锁销板412脱离加长轴芯组件430的卡接，使得伸缩固定梁41向后缩回一定距离，撞击或冲击的力量变弱或消失后，由于电磁锁固定件42通过拉簧组件423固定，电磁锁固定件42会受到拉簧的拉力而向伸缩固定梁41方向旋转直至转回至原位处，此时，伸出锁销板412再次受到加长轴芯组件430的阻挡，但伸出锁销板412位于加长轴芯组件430的后方处，如此使得伸缩固定梁41向内缩回一定距离，避免伸缩固定梁41继续与撞击或冲击物紧密接触而造成进一步地破坏，有效地达到了及时缩回的目的。
如图3和图7所示，在某些实施例中，拉簧组件423包括有一第一拉簧4231及一 吊环螺钉4232，第一拉簧4231的一端与电磁锁固定件42连接，第一拉簧4231的另一端与吊环螺钉4232的吊环连接，吊环螺钉4232的螺杆固定在第二固定件424上。其中，第一拉簧4231用于拉紧电磁锁固定件42，在电磁锁固定件42相对转轴421发生远离伸缩固定梁41的旋转时，使得电磁锁固定件42能转回至原位，第一拉簧4231与转轴421配合使得电磁锁固定件42可以必要时发生一定的旋转，避免伸缩固定梁41受到强力撞击或冲击时，固定在电磁锁固定件42上的电磁锁43遭受破坏或者避免外界的撞击物或冲击物发生损坏。在附图3所示的实施例中，电磁锁固定件42靠近拉簧组件423的一端设有一圆孔428，第一拉簧4231的吊钩勾设在圆孔428中，如此实现电磁锁固定件42与第一拉簧4231的连接。
在本实施例中，如图7所示，第二固定件424包括有一第一固定底座4241及一自第一固定底座4241向上延伸而成的吊环固定件4243，第一固定底座4241的两侧分别设有一第二安装孔4242，第二安装孔4242呈长条状；吊环螺钉4232固定在吊环固定件4243上。由于第一固定底座4241的两侧分别设有一长条状的第二安装孔4242，如此安装使用时，可以随意调节第二固定件424的位置，从而调节第一拉簧4231的拉力。
但是，在实际使用中，由于第一拉簧4231的拉力相对较大，通过人力移动第二固定件424的位置来调节第一拉簧4231的拉力时相对费力，不方便调节。为轻松地调节第一拉簧4231的拉力，在本实施例中，如图7所示，吊环固定件4243上还设有一第一螺孔4244；第二固定件424的上方处还设有一拉簧调节装置425，拉簧调节装置425包括有一第二固定底座4251及一螺栓4252，第二固定底座4251上开设有若干安装孔以通过螺钉等紧固件固定于所述底板100上，且自该第二固定底座4251顶面向上延伸形成有一螺栓安装部4253，螺栓安装部4253上设有一第二螺孔，螺栓4252穿过第二螺孔后螺合于吊环固定件4243的第一螺孔4244中。安装使用时，先将拉簧调节装置425与第二固定件424连接好，当需要调整第二固定件424的位置时，先松动第二固定件424上第二安装孔4242中的螺钉等紧固件，然后通过旋转拉簧调节装置425上的螺栓4252，使得第二固定件424相对于拉簧调节装置425向上或向下运动，当调整好后，再将第二固定件424上第二安装孔4242中的螺钉等紧固件固定住，如此实现第一拉簧4231的拉力调节。其中 ，通过旋转螺栓4252来进行调整第二固定件424的位置，更为方便省力。
在本实施例中，如图5和图6所示，加长轴芯组件430包括有一第一加长套431、第二加长套432及加长轴芯433，第一加长套431的一端与所述锁舌434固定连接，第一加长套431的另一端固定设于第二加长套432中，加长轴芯433的一端固定在第二加长套432内，加长轴芯433的另一端伸出以卡接伸出锁销板412或缩回锁销板411。装配好后，加长轴芯组件430可随着电磁锁43的锁舌434在锁舌安装孔426中来回移动，从而实现伸出锁销板412或缩回锁销板411的卡接或解锁。
具体地，所述电磁锁固定件42的中部设有一柱状体427，所述锁舌安装孔426设置于所述柱状体427上，第一加长套431包括有一第一空心圆柱体4311，第一空心圆柱体4311的底面上开设有一第三螺孔，一螺钉4313穿设所述第三螺孔并穿入所述锁舌434以实现第一加长套431与锁舌434的固定连接，第一空心圆柱体4311的顶部边沿向外延伸形成有一圆环状的凸台4312；第二加长套432包括有一第二空心圆柱体4321，第二空心圆柱体4321的底面上开设有一通孔，通孔的内径与第一空心圆柱体4311的外径匹配，优选地，本实施例中，所述第二空心圆柱体4321的内侧壁的底部及顶部位置处分别至少设有二用于安装卡簧(图中未示出)的卡孔4322；加长轴芯433包括有一第一圆柱体4331、一自该第一圆柱体4331的顶面向外延伸而成的第二圆柱体4332以及一自该第二圆柱体4332的顶面向外延伸而成的圆台4333，第一圆柱体4331的外径与第二空心圆柱体4321的内径匹配。安装时，先将第一加长套431套设在第二加长套432中，通过螺钉4313将第一加长套431螺合固定于电磁锁43的锁舌434上，然后在第二加长套432的内侧壁的底部位置处的卡孔4322中装上卡簧，卡簧卡紧在卡孔4322中且有部分伸出卡孔4322以抵接固定在第一加长套431上，再将加长轴芯433套设在第二加长套432中，最后在第二加长套432的内侧壁的顶部位置处的卡孔4322中装上卡簧，卡簧卡紧在卡孔4322中且有部分伸出卡孔4322以抵接固定在加长轴芯433上，如此，第一加长套431及加长轴芯433固定在第二加长套432中，实现连接。当然，在其他一些实施例中，可以使用螺钉等紧固件将第一加长套431、第二加长套432及加长轴芯433进行连接固定。
本实施例中，如图3和图4所示，伸出锁销板412包括有一第五固定底座4121及 一自该第五固定底座4121向外延伸而成的第一锁销4122；缩回锁销板411包括有一第六固定底座4111及一自该第六固定底座4111向外延伸而成的第二锁销4112，安装使用时，第一锁销4122及第二锁销4112相对伸缩固定梁41凸出，加长轴芯组件430卡接在第一锁销4122或第二锁销4112上以实现固定。在本实施例中，为方便调节伸出锁销板412与缩回锁销板411的位置，可理解地，伸缩固定梁41上至少设有一长条孔413，伸出锁销板412的第五固定底座4121及缩回锁销板411的第六固定底座4111均通过螺钉等紧固件固定在长条孔413上，如此，伸出锁销板412及缩回锁销板411可在长条孔413上调节相对位置，以满足不同间距的需求。
参照图3及图8，在附图所示的实施例中，所述锁定装置40还包括有一手动解锁组件44，手动解锁组件44包括有一第三固定底座441及一拔叉442，第三固定底座441上设有若干第三安装孔447以通过螺钉等紧固件固定于所述底板100上，以及一拔叉安装孔443，且自第三固定底座441向上延伸形成有一拨叉挡板444；拔叉442包括有一叉接件4421及一旋转固定件4422，叉接件4421固定于旋转固定件4422的上端部，叉接件4421的一侧抵接于加长轴芯组件430上，叉接件4421的另一侧抵靠于拨叉挡板444的内侧上，旋转固定件4422的另一端穿过拔叉安装孔443固定在第三固定底座441上，旋转固定件4422上端部的表面向内凹陷形成有一第一多边形凹槽4423，以通过该第一多边形凹槽4423转动旋转固定件4422，从而使得与叉接件4421抵接的加长轴芯组件430向内运动缩回。基于上述设计，在某些需要人为地解除锁定装置40的锁定的情况下(例如断电或发生故障时)，可通过一解锁工具70套设在旋转固定件4422的第一多边形凹槽4423中，旋转该解锁工具70以转动旋转固定件4422，从而带动与旋转固定件4422固定连接的叉接件4421发生旋转，叉接件4421旋转时使得加长轴芯组件430向内运动缩回，如此，伸出锁销板412或缩回锁销板411可脱离加长轴芯组件430的卡接，从而实现解锁。
通常地，手动解锁组件44在旋转后无法自动复位，需要人工再次进行旋转，如此相对麻烦，为方便手动解锁组件44进行复位，在本实施例中，如图8所示，手动解锁组件44还包括有一第二拉簧445，所述第二拉簧445的一端与叉接件4421 连接，且第三固定底座441上对应第二拉簧445的下方位置处还向上延伸形成有一拉簧固定板446，第二拉簧445的另一端固定在拉簧固定板446上。手动旋转手动解锁组件44时将克服第二拉簧445的拉力作用而使得拔叉442发生旋转，解锁完成后，松开解锁工具70，拔叉442在第二拉簧445的拉力作用下旋转回原位，实现手动解锁组件44的复位。
在本申请中，由于电磁锁固定件42通过拉簧组件423固定在一第二固定件424上，拉簧组件423的拉力较大，使电磁锁固定件42靠近拉簧组件423的一端有向伸缩固定梁41倾斜的趋势，有可能造成无法正常卡接伸出锁销板412或缩回锁销板411。为了使电磁锁固定件42工作时保持正位，如图3和图9所示，锁定装置40还包括有一托挡块45，其包括有一第四固定底座451及一设于所述第四固定底座451上的托挡部452，第四固定底座451上设有若干呈长条状的第四安装孔453；托挡部452呈阶台状，托挡部452用于承托电磁锁固定件42靠近拉簧组件423的一端，以限制电磁锁固定件42的位移，即用于限制电磁锁固定件42旋转极限位。其中，电磁锁固定件42承托在托挡部452的低阶台位置处，托挡部452的高阶台可以限制电磁锁固定件42向伸缩固定梁41倾斜，达到承托及限位的目的，使得该锁定装置40正常工作。
继续参照图1及图2，在某些实施例中，所述伸缩组件30包括一齿条31及驱动机构，所述齿条31固定一第一安装板310上，所述第一安装板310位于所述底板100上方，其末端与填隙板20连接，所述驱动机构包括有电机321、减速机构322以及第一齿轮323，所述电机321固定于底板100上，其受控于控制器，所述减速机构322连接于电机321输出轴，所述第一齿轮323与减速机构322连接，并与所述齿条31啮合。基于该设计，电机321接收到控制器的指令后工作，使得第一齿轮323转动，从而使得与该第一齿轮323啮合的齿条31移动，以带动填隙板20伸出或缩回。
优选地，在某些实施例中，如图1和图10所示，所述伸缩组件30还包括有至少一辅助伸缩装置33，所述辅助伸缩装置33位于所述齿条31一侧并与其平行设置，该辅助伸缩装置33包括一滑动机构331，所述滑动机构331包括有固定于所述箱体10底板100上的第二安装板3311，所述第二安装板3311上设有至少一滑块33 12，所述滑块3312上设有一导轨3313，所述导轨3313与一导轨固定臂3316固定连接，该导轨固定臂3316末端与填隙板20连接，本实施例中，设有两辅助伸缩装置33，分别位于齿条31两侧，每一辅助伸缩装置33设置有两滑块3312，且所述导轨固定臂3316采用横截面大致呈∏型的槽钢。
在本实施例中，位于所述齿条31左侧的辅助伸缩装置33的导轨固定臂3316上设有一开关撞块3314，该辅助伸缩装置33还包括有一检测装置332，所述检测装置332包括固定于底板100上的第三安装板3322，所述第三安装板3322两端分别设有一行程开关3321，以当开关撞块3314撞击行程开关3321时，发送信号至控制器以检测填隙板20的位置状态；而在位于所述齿条31右侧的辅助伸缩装置33的导轨固定臂3316上设有一挡块3315，所述挡块3315包括自导轨固定臂3316外表面向外延伸形成的第一连接板3317及自该第一连接板3317向外弯折形成的第二连接板3318，该辅助伸缩装置33还包括有一限位装置333，所述限位装置333包括固定于底板100上的第四安装板3331，所述挡块3315的第二连接板3318位于第四安装板3331上，且该第四安装板3331两端分别设有一限位块3332，以在导轨固定臂3316运动时，通过两限位块3332限制挡块3315的运动距离，从而限定导轨固定臂3316的运动距离。基于上述设计，当齿条31移动时，可带动填隙板20移动，从而使得与填隙板20连接的两导轨固定臂3316移动，当列车进站停稳后，齿条31驱动填隙板20伸出，右侧的导轨固定臂3316上设置的挡块3315运动至触碰第四安装板3331下端的限位块3332的同时，左侧的导轨固定臂3316上的开关撞块3314撞击位于第三安装板3322下端的行程开关3321，此时该行程开关3321发送信号至控制器，以使得电机321停止工作，填隙板20伸出完成，方便乘客上下车；而当列车关门后，控制器发送信号至电机321，电机321工作，使得齿条31反向移动，带动填隙板20缩回，从而带动两辅助伸缩装置33反向移动，右侧的导轨固定臂3316上设置的挡块3315运动至触碰第四安装板3331上端的限位块3332的同时，左侧的导轨固定臂3316上的开关撞块3314撞击位于第三安装板3322上端的行程开关3321，此时该行程开关3321发送信号至控制器，以使得电机321停止工作，此时填隙板20缩回完毕。
继续参照图1及图2，在某些实施例中，所述伸缩踏板装置1还包括有一手动缩 回装置，所述手动缩回装置包括自所述底板100向上延伸形成的第三空心圆柱体51，该第三空心圆柱体51顶部设有一第二齿轮52，所述第二齿轮52与齿条31啮合，且其上设有一凹槽53，以通过凹槽53转动第二齿轮52，从而使得齿条31移动。可理解地，本实施例中，所述底板100上设有一安装座54，所述第三空心圆柱体51设于所述安装座54上。基于上述设计，当列车断电或发生故障时，可通过该手动缩回装置使得填隙板20缩回箱体10内，即可通过一解锁工具70套设在凹槽53中，旋转该解锁工具70以转动所述第二齿轮52，从而可使得与第二齿轮52啮合的齿条31移动。
继续参照图1及图11，在某些实施例中，所述伸缩踏板装置1还包括有一手动锁定组件60，所述手动锁定组件60包括第五安装板61及锁定板62，所述第五安装板61固定于底板100上，自该第五安装板61向上延伸形成有一第一柱状体63，该第一柱状体63上插设有一第二柱状体64，该第二柱状体64上端部的表面向内凹陷形成有一第二多边形凹槽65，所述锁定板62套设固定于所述第二柱状体64上，且其末端一侧形成有一钩状体66，所述第一安装板310一端设有一销子311。基于该设计，当列车站台伸缩踏板装置1检修时，可通过该手动锁定组件60手动锁定，即当填隙板20缩回完毕，即第一安装板310靠近手动锁定组件60时，可通过一解锁工具70套设在第二多边形凹槽65中，旋转该解锁工具70以转动第二柱状体64，使得套设于第二柱状体64上的锁定板62末端的钩状体66勾住所述伸缩组件30中第一安装板310上的销子311，从而锁定该伸缩组件30，使得填隙板20不再移动。可理解地，如图1所示，所述锁定板62上方设有一行程开关601，在钩状体66勾住销子311时，发送信号至控制器以检测填隙板20的位置。
优选地，本实施例中，所述锁定板62底面设有一第三柱状体67，所述手动锁定组件60还包括有两自所述第五安装板61顶面向上延伸形成的第六安装板68，两第六安装板68间形成有一用于放置第三柱状体67的导向放置槽69，所述导向放置槽69的前端部形成有大致呈V字型结构的开口。基于该设计，当列车站台伸缩踏板装置1不需检修或检修完毕时，可通过旋转套设于第二多边形凹槽65的解锁工具70以转动第二柱状体64，从而使得锁定板62底面的第三柱状体67进入导向放置槽69内，以固定锁定板62，防止其转动影响伸缩踏板装置1的工作。
可理解地，本实施例中，列车进站停稳，屏蔽门系统收到允许开门信号时，控制器控制电机321工作，使得齿条31移动，以驱动填隙板20伸出，右侧的导轨固定臂3316上设置的挡块3315运动至触碰第四安装板3331下端的限位块3332的同时，左侧的导轨固定臂3316上的开关撞块3314撞击位于第三安装板3322下端的行程开关3321，此时该行程开关3321发送信号至控制器，以使得电机321停止工作，填隙板20伸出完成，此时，锁定装置40的伸缩固定梁41上的伸出锁销板412卡接于与电磁锁43的锁舌434固定连接的加长轴芯组件430上，伸缩固定梁41伸出并固定稳定，伸缩固定梁41不会出现向内缩回的情况；而当列车关门后，控制器发送信号至电机321，电机321工作，使得齿条31反向移动，带动填隙板20缩回，从而带动两辅助伸缩装置33反向移动，右侧的导轨固定臂3316上设置的挡块3315运动至触碰第四安装板3331上端的限位块3332的同时，左侧的导轨固定臂3316上的开关撞块3314撞击位于第三安装板3322上端的行程开关3321，此时该行程开关3321发送信号至控制器，以使得电机321停止工作，此时填隙板20缩回完毕，此时，伸缩固定梁41上的缩回锁销板411卡接于与电磁锁43的锁舌434固定连接的加长轴芯组件430上，伸缩固定梁41缩回并固定稳定，伸缩固定梁41不会出现向外伸出的情况。
参照图12，可理解地，本申请的列车站台伸缩踏板装置1可通过螺栓103与列车站台板安装，该伸缩踏板装置1中箱体10的上盖上可设置防滑槽以防止乘客滑倒，其包括有可打开的检修板1011及一固定板1012，检修板1011打开时通过撑杆组件102支撑，所述固定板1012上固定有梳齿状装置106，填隙板20上也固定有梳齿状装置107，两者相互配合，防止杂物进入箱体内，且该固定板1012上设有警示灯带104以提醒乘客注意；箱体10的开口处围绕填隙板20可设置密封胶条，以防止灰尘等杂物和雨水进入箱体10内；且填隙板20末端即与列车触碰的一端可设置梳齿橡胶块105，以防止与列车刮蹭时损坏列车。
综上所述，本申请通过伸缩组件推动填隙板穿过箱体开口伸出或缩回箱体内，以使得填隙板在列车进站时可填补列车与站台之间的空隙，使列车车厢与站台无缝连接，方便乘客进出，并可在列车未进站时给铁道留出较大空间，利于列车快速通过，避免列车与站台发生碰撞，且通过设置的锁定装置可有效保证填 隙板伸出及缩回的固定效果，在其受到撞击或冲击时可即时实现缩回，即当填隙板伸出或缩回时，锁定装置中的伸缩固定梁跟随填隙板伸出或缩回，使得伸出锁销板或缩回锁销板可卡紧在与电磁锁的锁舌固定连接的加长轴芯组件上，实现不同位置的固定锁合，其可以有效保证伸出及缩回的固定效果；且当该锁定装置的伸缩固定梁受到撞击或冲击时，伸缩固定梁将撞击或冲击的力传递加长轴芯组件，加长轴芯组件再将力量传递给电磁锁固定件，可避免造成电磁锁的锁舌的损坏，同时，当撞击或冲击的力量大于电磁锁固定件所连接的拉簧组件的力时，电磁锁固定件发生远离伸缩固定梁的旋转，并带动电磁锁随之旋转，如此，伸出锁销板脱离加长轴芯组件的卡接而使伸缩固定梁向后移动缩回一定距离，从而避免继续与撞击或冲击物紧密接触而造成进一步地破坏，有效地达到了及时缩回的目的。
以上所述仅为本申请的优选实施例，而非对本申请做任何形式上的限制。本领域的技术人员可在上述实施例的基础上施以各种等同的更改和改进，凡在权利要求范围内所做的等同变化或修饰，均应落入本申请的保护范围之内。
