请参阅图1至图7，本申请第一实施例提供了一种折叠器，包括下折叠部10，具有第一连接端11。下折叠部10侧壁上设有贯通侧壁内外的轴向缝隙101，通过缩小轴向缝隙101的宽度而使轴向缝隙101变小，以便将下折叠部10以抱紧的方式固定在待连接的部件（滑板车前叉组件或自行车前叉组件）上。上折叠部20，具有第二连接端21，第二连接端21与第一连接端11枢接连接。第一连接端11和第二连接端21分别用于连接待连接的两个部件，例如滑板车的车架组件和车把组件，当第一连接端11连接车架组件，则第二连接端21连接车把组件，则反之。可选地，第一连接端11的外壁上开设有第一枢接孔102；第二连接端21的外壁上开设有第二枢接孔201，第二枢接孔201和第一枢接孔102之间装设有枢接轴70，第一连接端11和第二连接端21通过枢接轴70枢接连接。以及，弹性锁扣机构，弹性锁扣机构连接于第一连接端11和第二连接端21之间；弹性锁扣机构包括提供自动锁扣驱动力的弹性件50；弹性锁扣机构具有锁扣状态和脱扣状态；弹性锁扣机构锁扣时，上折叠部20扶正，弹性件50驱动弹性锁扣机构自动扣合，使第一连接端11和第二连接端21锁扣连接。弹性锁扣机构脱扣时，外力驱动弹性锁扣机构打开，第一连接端11和第二连接端21脱扣。
在一个实施例中，弹性锁扣机构还包括手柄60、卡勾件40以及第一勾块22；手柄60的一端枢接在第一连接端11上；可选地，手柄60通过一枢接轴90枢接于第一连接端11的外壁。卡勾件40转动连接于第一连接端11或第二连接端21上。卡勾件40具有第二勾块401；且手柄60带动卡勾件40转动。可选地，卡勾件40可直接设于手柄60上，可以理解为，卡勾件40是通过手柄60间接转动连接于第一连接端11或第二连接端21上；手柄60转动时，卡勾件40随手柄60转动。
第一勾块22连接于第一连接端11或第二连接端21上，可选地，第一勾块22可通过固定或者可拆卸的结构连接于第一连接端11或第二连接端21上。弹性件50的一端抵于第一连接端11或第二连接端21上，弹性件50的另一端抵于卡勾件40或手柄60上，可选地，弹性件50为弹片、弹簧或者弹性橡胶等。当第一勾块22位于第一连接端11上时，卡勾件40连接于第二连接端21上，则反之。弹性锁扣机构锁扣时，上折叠部20扶正，上折叠部20带动第一勾块22向第二勾块401方向转动；同时，弹性件50驱动手柄60或卡勾件40向第一勾块22方向转动，使第二勾块401扣合第一勾块22。或者，上折叠部20和弹性件50同时带动卡勾件40向第一勾块22方向转动，使第二勾块401扣合第一勾块22，实现自锁。此时，下折叠部10和上折叠部20被锁在展开状态无法折叠。弹性锁扣机构脱扣时，外力驱动手柄60的自由端背离上折叠部20转动预定角度，并带动卡勾件40转动，使第一勾块22和第二勾块401脱扣。此时，下折叠部10和上折叠部20从锁扣状态切换到脱扣状态，从而上折叠部20能折叠在下折叠部10上。当手柄60由于意外转动，且手柄60相对上折叠部20发生轻微转动且转动的角度小于预定角度时，第一勾块22和第二勾块401也不会发生脱扣，从而提高了安全性。可选地，手柄60和卡勾件40可转动地设在第二连接端21，对应的，第一勾块22位于第一连接端11上，即第一连接端11上的部件和第二连接端21上的部件对调，同样也能实现锁扣。
在一个实施例中，手柄60上设有第一勾位81，第二连接端21的外壁对应设有第二勾位82，锁扣时，第二勾位82与第一勾位81卡勾连接。可选地，第一勾位81为设在手柄60上可上下拉动地勾块，对应的，第二勾位82为设在第二连接端21外壁上的挂勾，锁扣时，挂勾与勾块卡勾连接。向上拉动勾块可实现勾块与挂钩的脱扣。且勾块内设有弹簧，在松开勾块情况下，勾块在弹簧的作用下实现位置的复原。可选地，第一勾位81为手柄60顶端向上折叠部20方向延伸出的勾块，对应的，第二勾位82为设在贯穿第二连接端21外壁的勾孔，锁扣时，勾块与勾孔卡勾连接。
在一个实施例中，卡勾件40转动连接于第一连接端11，第二勾块22连接于第二连接端21。卡勾件40包括有两卡勾41和连接于两卡勾之间的连杆42，第二勾块401分别位于两卡勾41的一端；弹性件50一端抵于卡勾41背面；促使卡勾41向第一勾块22方向运动。手柄60的两侧面贯穿有滑槽62，两侧面为手柄60的左右侧面；连杆42穿过滑槽62，手柄60转动带动连杆42于滑槽62中滑动，以改变第一勾块22和第二勾块401的连接状态；可以理解为，卡勾件40是通过手柄60间接转动连接在第一连接端11上。滑槽62包括圆弧段621和脱扣段622，脱扣段622的一端与圆弧段621的一端连通，圆弧段621的圆心靠近卡勾件40；脱扣段622的延伸方向背离卡勾件40。上折叠部20扶正，且连杆42位于圆弧段621时，第一勾块22与第二勾块401卡扣连接，也就是说，连杆42在圆弧段621中滑动时，促使第一勾块22向第二勾块401运动，使两者紧扣在一起。手柄60朝第一连接端11转动到预定角度时，连杆42于圆弧段621滑到脱扣段622，以使第一勾块22与第二勾块401脱扣。可选地，脱扣段622可为弧形状、直线状或者其它形状。
可选地，弹性件50为拱形弹片，且拱形弹片为两个。第一连接端11上开设有安装腔103，安装腔103为两面开口结构，其便于弹性件50的安装。两卡勾41分别位于对应的安装腔103中，两拱形弹片分别安装于对应的安装腔103中，且拱形弹片的两端抵于安装腔103的内壁上，形成支撑点。拱形弹片的最高拱起点抵于卡勾41的背面，对卡勾41施加压力，使第二勾块401卡扣第一勾块22。可选地，拱形弹片为可变形的弹性金属材质或者可变形的弹性塑胶材质等。
在一个实施例中，折叠器还包括顶杆30，顶杆30包括有轴体31以及与轴体连接的杆体32，轴体31枢接于第一连接端11的外壁或者第二连接端21的外壁；杆体32的扣合端为球头形状，手柄60上凹设有扣槽61，锁扣时，扣槽61与杆体32的扣合端扣合，以将下折叠部10和上折叠部20锁定在非折叠状态下。通过这种结构设置使得手柄60与顶杆30之间的扣合不容易松脱，从而保证锁紧作用的可靠性。在手柄60松开时，顶杆30可以防止手柄60过度转动，需要人为施力手柄60，才能使手柄60克服顶杆30的阻力，从而达到安全性。当然，折叠器不局限于顶杆型折叠器。可选地，轴体31和杆体32为一体式连接结构，或者轴体31和杆体32为分体式连接结构，例如，杆体32为螺钉，对应的，轴体31上贯穿有螺纹孔，螺钉的螺纹段与螺纹孔螺纹连接，从而可根据情况来调节杆体32的长度，使用更加的灵活方便。且螺钉的下端是抵于手柄60的内壁上。
如图8-图14所示，为本申请的第二实施例，其与第一实施例的结构基本相同，其不同之处在于：卡勾件40为V字形扳手，卡勾件40的一端为扳手部402，另一端为第二勾块401，且第二勾块401与扳手部402呈V字形状。卡勾件40是安装于枢接轴90上的。扳手部402位于手柄60的下方，且弹性件50的一端抵于扳手部402的底面；弹性件50为扭簧，扭簧一端抵于第一连接端11上，扭簧另一端抵于扳手部402的底面，且扭簧套设在枢接轴90上。
弹性锁扣机构锁扣时，上折叠部20扶正，上折叠部20带动第一勾块22向第二勾块401方向转动，同时，弹性件50驱动扳手部402向第一勾块22转动，使第二勾块401与第一勾块22扣合。弹性锁扣机构脱扣时，手柄60转动到预定角度时，手柄60靠近扳手部402的一端抵压在扳手部402上并带动卡勾件40转动，以使第二勾块401与第一勾块22脱扣。在一个实施例中，上折叠部20靠近下折叠部10的一端装设有座体23，第二连接端21位于座体23上，即第二连接端21与上折叠部20为分体式设置，可选地，座体23的一端延伸出有紧插段231，紧插段231插入上折叠部20中，紧插段231的外壁与上折叠部20的内壁紧插在一起固定。
如图15-图19所示，为本申请的第三实施例，其与第一实施例的结构基本相同，其不同之处在于：卡勾件40一体连接于手柄60的侧面。弹性件50的一端抵于手柄60的一端。弹性件50为扭簧，扭簧的一端抵于第一连接端11上，扭簧的另一端抵于手柄60的底面。弹性锁扣机构锁扣时，上折叠部20扶正，上折叠部20带动第一勾块22向第二勾块401方向转动，同时，弹性件50驱动手柄60向第一勾块22转动；促使第一勾块22与第二勾块401扣合；弹性锁扣机构脱扣时，手柄60的自由端向背离第一勾块22方向转动到预定角度时，使第二勾块401与第一勾块22脱扣。
在一个实施例中，手柄60为了避让轴体31开设有避让腔601，轴体31穿过避让腔601；且避让腔601的内壁靠近下折叠部10的一端形成有勾部602，当第二勾块401与第一勾块22脱扣后，继续转动手柄60一定的角度后，轴体31与勾部602脱扣。弹性锁扣机构脱扣时，脱扣的顺序依次为：顶杆32的扣合端与扣槽61先脱扣，接着，第二勾块401与第一勾块22脱扣，最后，轴体31与勾部602脱扣，通过三道钩扣结构，进一步防止上折叠部20倾倒。可选地，轴体31上套设有偏置件33，偏置件33的一端抵于第一连接端11上，偏置件33的另一端抵于杆体32上，促使杆体32朝扣槽61方向转动，从而使杆体32的扣合端紧扣在扣槽61内。可选地，偏置件33为扭簧。
如图20-图25所示，为本申请的第四实施例，其与第二实施例的结构基本相同，其不同之处在于：卡勾件40转动连接于第二连接端11，第二勾块22连接于第一连接端11。卡勾件40转动连接于第二连接端11的内部，可选地，卡勾件40通过转轴100转动连接于第二连接端11上；第一勾块22连接于第一连接端11的内部。
弹性件50内置于第二连接端11内部，且弹性件50一端抵于卡勾件40上；促使卡勾件40向第一勾块22转动；可选地，弹性件50为扭簧，其一端抵于第二连接端11的内壁，另一端抵于卡勾件40上，且扭簧套设于转轴100上。手柄60的一端延伸出有触发部63。弹性锁扣机构锁扣时，上折叠部20扶正，上折叠部20和弹性件50同时带动卡勾件40向第一勾块22方向转动，使第二勾块401扣合第一勾块22。弹性锁扣机构脱扣时，手柄60转动到预定角度时，触发部63伸入第一连接端11的内部并推动卡勾件40向远离第一勾块22方向转动，使第一勾块22和第二勾块401脱扣。
且折叠器在市面现有折叠器基础上进行变更，保留折叠器基本原理，不影响折叠器可靠性。且折叠器折叠步骤只增加了解锁扣这一步，其余折叠步骤与常见的折叠方式相同，使用方便，结构简单，装配简单。
本申请还提供一种折叠车辆，包括：车架组件和车把手组件以及的折叠器；折叠器连接于车架组件和车把手组件之间。当下折叠部10与车架组件连接时，则上折叠部20与车把手组件连接，则反之。折叠器可应用到折叠自行车、折叠平衡车或者折叠滑板车等。
