Description

一种加强型滑板车折叠装置
技术领域
本发明涉及一种加强型滑板车折叠装置。
背景技术
传统的滑板车的车头和底板是固定连接的，采用这个结构的滑板车结构稳固、安全性高，但是不使用时，非常占用空间，不易被存放收纳，且携带不方便；虽然现在市面上也存在一些可折叠的滑板车，但是其折叠装置结构过于复杂，操作繁琐，安全性和可靠性不高。
发明内容
为了克服现有技术的不足，本发明提供一种加强型滑板车折叠装置，该折叠装置具有操作简单容易、安全可靠的特点。
本发明解决其技术问题所采用的技术方案是：
一种加强型滑板车折叠装置，其特征在于包括伸缩管机构，所述伸缩管机构的一端与滑板车的车头管中下部铰接，另一端与滑板车的底板中前部铰接，滑板车的车头管下部与底板前部铰接，使伸缩管机构、车头管、底板相互铰接围成三角形，所述伸缩管机构包括固定管和套装在固定管内的伸缩管，并且伸缩管可沿固定管轴向滑动，在伸缩管机构上设置有可将固定管和伸缩管分别定位在伸展状态和收合状态的定位机构，且伸缩管机构上还设置有可使固定管和伸缩管限制于伸展状态的安全锁位装置。
所述定位机构包括分别设置在伸缩管侧面的两组弹珠组件，所述的两组弹珠组件在伸缩管侧面上的轴向分布，并具有一定间距。
所述弹珠组件包括复位弹簧和分布在伸缩管两侧弹珠，在固定管两侧设置有与弹珠组件对应的定位孔，在伸缩管两侧上开设可供对应弹珠伸出的弹珠孔，使弹珠可滑出并卡掣在固定管的定位孔内。
所述复位弹簧安装在伸缩管内，且两端分别顶压在两个弹珠的后端面，当伸缩管滑动至弹珠与定位孔对应的位置时，弹珠会由于复位弹簧的弹力自动卡掣在定位孔内。
所述固定管在定位孔上设置有按钮，当弹珠滑进定位孔时，按下按钮，可使弹珠滑出定位孔。
所述安全锁位装置包括设置在伸缩管上侧面的安全弹珠组件，所述安全弹珠组件包括设置在伸缩管内的锁位弹簧和安全弹珠，在伸缩管上侧面上开设可供安全弹珠伸出的安全弹珠孔，所述锁位弹簧一端顶压在伸缩管内壁，另一端顶压在安全弹珠尾部，在固定管上侧面开设有与安全弹珠对应的滑槽，当伸缩管机构伸展至一定长度时，安全弹珠可从安全弹珠孔滑出至滑槽，当固定管和伸缩管处于伸展状态时，安全弹珠孔与滑槽的底部有一定距离。
所述固定管在滑槽上设置有安全按钮，当安全弹珠滑进滑槽时，按下安全按钮，可使安全弹珠滑出滑槽。
所述弹珠和安全弹珠的头部为半球形结构，其尾部设置有环形阶梯卡块。
所述车头管在与底板铰接处设置有定位凸块，在底板上设置有与定位凸块对应的调紧螺丝，当伸缩管伸长至所需展开位置时，调紧螺丝能够调节至压紧在定位凸块的端面上。
本发明的有益效果是：滑板车底板与车头管铰接，并在二者之间铰接一个伸缩管机构，使滑板车底板、车头管、伸缩管机构围成一个三角形，且伸缩管机构所在边是可变化的，故当伸缩管缩短或伸长时，滑板车就可以相应的折叠或展开，使滑板车可折叠收纳，并方便携带，伸缩管机构机构通过安装在伸缩管上的弹珠组件和设置在固定管上的定位孔配合定位伸缩的长度，当伸缩管的弹珠组件滑动至定位孔时，弹珠组件的弹珠会由于复位弹簧的弹力自动卡掣在定位孔内，实现伸缩管机构的固定和定位，从而使滑板车折叠或展开时为一固定机构，整个折叠展开操作简单快捷。
进一步，伸缩管机构上还设置有安全锁位装置，当伸展状态下弹珠组件失效，安全锁位装置可保证滑板车不会立刻缩回折叠，提高其安全性和可靠性。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明伸长使滑板车展开时结构示意图；
图2是本发明缩短使滑板车折叠时局部结构示意图；
图3是本发明伸长时的局部结构示意图；
图4是本发明横向剖面结构示意图；
图5是本发明纵向剖面结构示意图。
具体实施方式
参照图1至图5，1至图5是本发明一种具体实施例的结构示意图，如图所示，一种加强型滑板车折叠装置，包括伸缩管机构1，伸缩管机构1的一端与滑板车的车头管2中下部铰接，另一端与滑板车的底板3中前部铰接，滑板车的车头管2下部与底板3前部铰接，使伸缩管机构1、车头管2、底板3相互铰接围成三角形，伸缩管机构1包括固定管11和套装在固定管11内的伸缩管12，并且伸缩管12可沿固定管11轴向滑动，在伸缩管机构1上设置有两组可将固定管11和伸缩管12分别定位在伸展状态和收合状态的弹珠组件4, 两组弹珠组件4在伸缩管12侧面上的轴向分布，并具有一定间距，当伸缩管机构1缩短或伸长时，滑板车就可以相应的折叠或展开，，并通过两组弹珠组件4分别使伸缩管机构1缩短或伸长时定位固定，实现滑板车的折叠收纳功能，并方便携带。
如图所示，弹珠组件4包括复位弹簧42和分布在伸缩管12两侧弹珠41，在固定管11两侧设置有与弹珠组件4对应的定位孔111，在伸缩管12两侧上开设可供对应弹珠41伸出的弹珠孔121，复位弹簧42安装在伸缩管12内，且两端分别顶压在两个弹珠41的后端面，当伸缩管12滑动至弹珠41与定位孔111对应的位置时，弹珠41会由于复位弹簧42的弹力自动卡掣在定位孔111内，固定管11在定位孔111上设置有按钮112，当弹珠41滑进定位孔111时，按下按钮112，可使弹珠41滑出定位孔111。
进一步，如图所示，伸缩管机构1上还设置有安全锁位装置6，包括设置在伸缩管12上侧面的安全弹珠组件，安全弹珠组件包括设置在伸缩管12内的锁位弹簧62和安全弹珠63，在伸缩管12上侧面上开设可供安全弹珠63伸出的安全弹珠孔122，锁位弹簧62一端顶压在伸缩管12内壁，另一端顶压在安全弹珠63尾部，在固定管11上侧面开设有与安全弹珠63对应的滑槽113，当伸缩管机构1伸展至一定长度时，由于锁位弹簧62的弹力作用，安全弹珠63可从安全弹珠孔122滑出至滑槽113，当固定管11和伸缩管12处于伸展状态时，安全弹珠孔122与滑槽113的底部有一定距离，固定管11在滑槽113上设置有安全按钮114，当安全弹珠63滑进滑槽113时，按下安全按钮114，可使安全弹珠63滑出滑槽113。
滑板车未使用时，处于折叠状态，当需要展开滑板车，首先按下伸缩管机构1两侧的按钮112，使弹珠41滑出定位孔111，当弹珠41没卡掣在固定管11的定位孔111内时，伸缩管12可在固定管11内轴向自由滑动，这时逆时针翻转车头管2，伸缩管12被带动伸长，当伸展至一定长度时，安全弹珠63首先从安全弹珠孔122滑出至滑槽113，继续翻转，当滑动所需展开位置时，靠近底板3的弹珠组件4的弹珠41与定位孔111对应，弹珠41被顶压进定位孔111内，这时滑板车展开并为一固定结构，这时安全弹珠63与滑槽113的底部有一定的安全距离，当弹珠组件4失效，安全锁位装置6可保证滑板车不会立刻缩回折叠，提高其安全性和可靠性；当需要收叠时，同时按下按钮112和安全按钮114，顺时针翻转车头管2，当滑动所需折叠位置时，靠近车头管2的弹珠组件4的弹珠41与定位孔111对应，弹珠41被顶压进定位孔111内，这时滑板车折叠并为一固定结构；整个折叠展开操作简单快捷。
在本发明中滑槽113为前端开口的U型孔，在实际应用中还可设置为不开口的长条形孔，以实现双向限位保护的功能，在此不做详述。
再进一步，如图所示，弹珠41和安全弹珠63的头部为半球形结构，其尾部设置有环形阶梯卡块411，环形阶梯卡块411外径比其头部大，使弹珠41和安全弹珠63不能完全滑出，可防止弹珠41和安全弹珠63过度滑出而使弹珠组件4或安全弹珠组件失效，提高其可靠性和安全性；而弹珠41和安全弹珠63的头部设计为半球形结构，弹珠41和安全弹珠63不用完全滑进伸缩管12，而是只需头部以下部分滑入即可，这时转动车头管2，带动伸缩管机构1滑动即可把弹珠41或安全弹珠63顶压进伸缩管12，这样就可让按钮112和安全按钮114的伸长端设计短一点，而不至于过长而担心过度按压使按钮112或安全按钮114的伸长端卡掣进伸缩管12内，使整个伸缩管机构1操作的更加便利。
如图所示，车头管2在与底板3铰接处还设置有定位凸块21，在底板3上设置有与定位凸块21对应的调紧螺丝31，当伸缩管12伸长至靠近底板3的弹珠组件4的弹珠41与定位孔111对应位置时，即滑板车处于张开状态，调节调紧螺丝31使其压紧定位凸块21，从而消除张开状态时由于弹珠41与定位孔111之间间隙产生的前后松动，使得伸缩管机构1结构更为紧凑可靠，而且保证伸缩管12不至于过度伸长而滑出固定管11，进一步提高伸缩管机构1的可靠性和安全性。
上述仅为本发明一种优选实施例，在实际应用中还可以作出相应的变化，例如定位机构5和安全锁位装置6可设计为：销钉定位、卡齿定位等其他定位方式，在此不作详述。
所以，熟悉本领域的技术人员在不违背本发明精神的前提下所作的等同的变换或相应的改动，都应该属于本发明的保护范围内。
