Description
本发明涉及一种滑板车。
我们知道，为便于携带、存放，当前的滑板车基本上都是做成可以收折的。当前滑板车收折结构种类繁多，但基本上都是比较复杂，而且往往需要两只手同时操作才能实现，因此这些结构的收折操作不太方便，生产成本偏高。为此，也有人开发出了靠一只手来操作按钮来收折的滑板车，如专利号为2016214703435的滑板车和专利申请号为2016112448412的收折操作更方便的滑板车，它们都是靠按压按钮来实现收折的，这样在操作时比较费力和辛苦；而且对于把手管可伸缩的滑板车（绝大多数的滑板车都是如此），每次在折叠时都要把把手管缩到最短时才能操作，这种折叠的方式不太符合人们日常的操作习惯（人们的习惯是不管把手管伸缩在任何位置，都能收折操作），因此当前的单只手操作收折的滑板车有必要作进一步的改进。
本发明的目的是在于克服现有技术的不足，提供了一种结构更合理、符合人们折叠习惯、收折操作省力和方便的滑板车，其收折操作不受伸缩杆位置状态的影响。
一种手拉折叠的滑板车，包括前端带一对耦片的底板，设在底板尾端的后轮组件，通过摆动轴摆动连接在这对耦片中的叉管，套入到该叉管的套管部中的转向杆，与该转向杆上端连接的伸缩杆，连接在转向杆下端的前轮组件，装在该伸缩杆上端的把手，以及收折结构，其中：
所述叉管包括相通的圆形套管部和斜管部；
所述伸缩杆包括与该转向杆套接在一起的定管和可伸缩地套入到该定管中的动管，它们之间由伸缩锁紧组件锁紧；

上拉后，使钢性绳另一端的滑销在克服滑销复位簧的作用力后滑离展开到位槽或收合到位槽。
在对上述手拉折叠的滑板车的改进方案中，所述的下拉动杆分成上部分的齿条部和管状部，它们通过销轴连接；所述的齿条设在该齿条部上；所述带弹片的拉动销设在该管状部内。
在对上述手拉折叠的滑板车的改进方案中，在所述伸缩杆内设有使上拉动杆摆离该下拉动杆的拉动杆分离推件，其是弹性件。

在对上述手拉折叠的滑板车的改进方案中，在所述收折拉动件上设有开口夹。
由于操纵滑板车的折叠、展开，是靠收折拉动件带动上拉动杆往上移动的同时使其下部摆向下拉动杆后，使下拉动杆和上拉动杆的一部分齿条咬合在一起，进而联动地依次拉动下拉动杆、牵拉件、钢性绳后使滑销滑离展开或收合到位槽来实现的，这样不管伸缩杆的动管是在高位还是收缩到位，只要往上拉动收折拉动件，都可以使稍微摆动后的上拉动杆和下拉动杆的一部分齿条咬合在一起来实现滑板车的折叠或展开，从而使其收折、展开操作不受伸缩杆位置状态的限制，也就无需每次在折叠或展开滑板车时都要把伸缩管缩到最短状态才能操作，这就非常符合人们平常收合、展开滑板车的使用习惯，因此本发明的结构更合理；而且利用杠杆原理使上拉动杆下部摆向下拉动杆来操纵滑板车的收合、展开操作，这样可以使滑板车的收展操作更省力和方便。

所述叉管4包括相通的圆形套管部42和斜管部43（通常为方形管）；
所述伸缩杆6包括与该转向杆5套接在一起的定管61（在此，它们螺纹连接后再锁紧在一起）和通过高度调节弹性销可伸缩地套入到该定管61中的动管62，它们之间由伸缩锁紧组件63锁紧；
在所述耦片1上设有以该摆动轴为圆心的弧形面11、以及位于该弧形面11两端的展开到位槽12和收合到位槽13；
所述收折结构9包括钢性绳90、连接在该钢性绳90上下两端的牵拉件91和滑销92、钢性绳跨拉支点93、牵拉件复位簧94、滑销复位簧95、下拉动杆96、上拉动杆97、拉动杆复位簧98、上拉动杆摆动推件99以及收折拉动件100；所述牵拉件91和牵引件复位簧94套在该套管部42内壁和转向杆5外壁之间的那一段空间内，并可沿转向杆5的外壁上下滑动；所述的牵引件复位簧94使该牵拉件91往下复位（在此，牵引件复位簧94为压簧，其位于牵位件的上方，当然，它也可以是拉簧等）所述钢性绳跨拉支点93横穿在斜管部43靠近该套管部42的那一侧上；所述钢性绳90沿该斜管部43管内的长度方向经过且其上部跨在该钢性绳跨拉支点93上后其上、下端分别与该牵拉件91和滑销92连接；所述滑销复位簧95两端分别连接在该滑销92和摆动轴41上，该滑销92能沿该耦片1的弧形面11滑动并在该滑销复位簧95拉动下能滑落到该展开到位槽12或收合到位槽13中；在所述斜管部43上设有供滑销92滑进、滑出展开、收合到位槽时的避让条形孔431，这样就不会干涉到滑销的滑动；所述的上拉动杆97和拉动杆复位簧98设在该动管62内；所述的收折拉动件100套在该动管62外并可在该管外升降滑行，其通过连接销101与该动管62内的上拉动杆97连在一起；在所述动管62上设有长条形的连接销避让孔621；所述的下拉动杆96和上拉动杆摆动推件99设在该定管61内，并将下部伸入到定管61中的上拉动杆97夹在其中；所述的下推动杆96的上部伸入到该动管内；在所述下拉动杆96的下部内设有带弹片1021的拉动销102；在所述下拉动杆96、转向杆5上分别设有供该拉动销102露出来的销孔961、拉动销滑孔53；所述拉动销102与套在该转向杆5外的该牵拉件91连接，这样下拉动杆96在上拉动杆97带动下往上移动时，就可通过拉动销102作用在牵拉件91上来拉动钢性绳，以此来收折滑板车；为了实现上拉动杆带动下拉动杆上移来折叠或展开滑板车，在所述上拉动杆97和下拉动杆96上分别设有齿条971、962，所述的收折拉动件100往上拉带动该动管62内的上拉动杆97往上移动时，所述的上拉动杆摆动推件99能推动该上拉动杆97绕该连接销101摆向该下拉动杆96后，所述下拉动杆96和上拉动杆97之间的一部分齿条962、971咬合在一起，这样就可通过上拉动杆97拉动下拉动杆96往上移动，这时装在下拉动杆96内的拉动销102就会拉动该牵拉件91克服牵引件复位簧94的弹力后沿转向杆外壁往上滑动，接着该牵拉件91将钢性绳90沿钢性绳跨拉支点93的下外缘往
上拉后，就可拉动钢性绳另一端的滑销92在克服滑销复位簧95的作用力后滑离展开到位槽12来收折或收合到位槽13来展开滑板车。
从上可以看出，操纵滑板车的折叠、展开，是靠收折拉动件100带动上拉动杆97往上移动的同时使其下部摆向下拉动杆96后，使下拉动杆96和上拉动杆97的一部分齿条962、971咬合在一起，再联动地依次拉动下拉动杆96、牵拉件91、钢性绳90后使滑销92滑离展开或收合到位槽来实现的，这样不管伸缩杆的动管是在高位还是收缩到位，只要往上拉动收折拉动件100，都可以使稍微摆动后的上拉动杆97和下拉动杆96之间的一部分齿条971、962咬合在一起来实现折叠或展开滑板车，以使其收折、展开操作不受伸缩杆位置状态的限制，从而无需每次在折叠或展开滑板车时都要把伸缩管缩到最短状态才能操作，这就非常符合人们平常收合、展开滑板车的使用习惯，因此本发明的结构更合理；而且单手操作收折拉动件，并利用杠杆原理使上拉动杆下部摆向下拉动杆来操纵滑板车的收合、展开，这样可以使滑板车的收展操作更省力和方便。
作为较佳的实施方案，如图8所示，上拉动杆97和下拉动杆96的齿条971、962的齿形有些倾斜，它们单向咬合（当上拉动杆97向上拉时才咬合在一起）。
在本实施例中，如图6、7所示，为便于生产和组装，使所述的下拉动杆96分成上部分的齿条部963和管状部964，它们通过销轴103连接；所述的齿条962设在该齿条部963上；所述带弹片1021的拉动销102设在该管状部964内。优选地，在所述伸缩杆6内设有使上拉动杆97摆离该下拉动杆96的拉动杆分离推件104，这样当松开收折拉动件100，可避免下拉动杆96和上拉动杆97的齿条962、971仍咬合在一起影响收折结构9的复位。拉动杆分离推件104通常是弹性件，它可以是拉簧、压簧或折弯的弹性钢条、弹片等，在如图7所示的本实施例中，它是装在该上拉动杆97下端中的V型弹性钢条（其弹力不用很大，当松开收折按压件时，钢条能辅助分开上、下推动件的齿条即可），其对向该下拉动杆96，当上拉动杆下部摆向下拉动杆时，弹性钢条一端顶在下拉动杆上，而一旦松开收折拉动件，在弹性钢条的作用下，上、下拉动杆顺利分开。在本实施例中，所述下拉动杆96和上拉动杆97的齿条962、971在直线方向上分别通过分隔槽965、972分隔成两列，所述弹性钢条设在上拉动杆97的分隔槽965中，这样既有助于齿条之间的咬合，又有助于弹性钢条的安装和受力均衡。
上拉动杆摆动推件99可以是各种结构，只要当上拉动杆上移时能推动它的下部摆向下拉动杆，当上拉动杆下移复位能自动摆离下拉动杆即可。在本实施例中，如图6至8所示，上拉动杆97和上拉动杆摆动推件99通过斜台的方式来实现，如图4、8所示，所述的上拉动杆摆动推件99呈管状，其装入到该定管61内；所述上拉动杆97上端、下拉动杆96上端伸入到该上拉动杆摆动推件99的管内；在所述上拉动杆的下端上设有斜凸台973，在所述上拉动杆摆动推件99的内壁上设有倒U型的容纳槽991；所述上拉动杆在复位状态时其上的斜凸台973落入到该容纳槽991中，当上拉动杆及其上的斜凸台973往上移时，在容纳槽991上端面的作用下就可以使上拉动杆的下部摆向下拉动杆。
在本实施例中，如图1、2所示，在所述收折拉动件100上设有开口夹1001，当滑板车不使用时，可以将把手从伸缩杆的动管中取出来，并夹放到开口夹1001中，以节省滑板车的存放空间。
本实施例所示的滑板车是双把手的，当然它也可以是单把手的。
尽管参照上面实施例详细说明了本发明，但是通过本公开对于本领域技术人员显而易见的是，而在不脱离所述的权利要求限定的本发明的原理及精神范围的情况下，可对本发明做出各种变化或修改。因此，本公开实施例的详细描述仅用来解释，而不是用来限制本发明，而是由权利要求的内容限定保护的范围。
