Description

婴童三轮车前轮组收折机构
技术领域
本实用新型涉及一种婴童三轮车前轮组收折机构，特别涉及一种能有效降低婴童三轮车储运材积的婴童三轮车前轮组收折机构。
背景技术
婴童三轮车俗称慢跑车，其特色是在慢跑时可推动此三轮车。由于移动速度较一般婴儿车快，必须使用大尺寸的车轮才能稳定，一般采用的车轮直径至少16英吋以上，而一般婴儿车使用的车轮则通常在10吋以下。
由于前、后车轮都较大，使收折后的婴童三轮车仍然占相当庞大的纵向空间，造成储运的材积成本无法降低，尤其使用后想置于汽车后行李箱搬运，发现其占用相当多的行李空间，令人感到不便。
实用新型内容
为了解决上述因慢跑车的车轮尺寸较大而影响收折及储运材积的问题，本实用新型的目的在于提供一种婴童三轮车前轮组收折机构。
一种婴童三轮车前轮组收折机构，包括：
一支撑骨架，包括一前脚支架、一后脚支架、一上支架、一对座支架及一对收折关节组组接而成；
一前轮组，可往后掀动地枢接于前脚支架的下端；及
一连杆，连动于前轮组与支撑骨架之间。
优选的，该对座支架连动于前脚支架与后脚支架之间，后脚支架两侧的上端设有一对枢耳。
优选的，所述连杆连动于前轮组与该对座支架之间，并当该对座支架连动后脚支架时，经由连杆连动前轮组使随之回转。
优选的，所述前轮组包括一前轮座、一前叉轮臂及一前轮；所述前轮座可往后掀动地枢接于前脚支架的下端并经由连杆与座支架连动；所述前叉轮臂的上端可左、右回转地轴接于前轮座的下方，而以下端轴接前轮。 
优选的，所述前脚支架的下端装置一枢接座，使前轮组得以相对于前脚支架转动。
优选的，所述连杆的后端固接一横杆，通过横杆的两端分别与该对座支架枢接。
优选的，所述后脚支架两侧的下端可90度回转地分别套接一后轮组，所述后轮组包括一后轮座并且轴接一后轮。
优选的，该对座支架以前端和前脚支架枢接，以后端和后轮座枢接。
优选的，所述上支架的上端设有一握持部，两侧通过枢耳与后脚支架两侧的上端枢接，两侧的端部通过该对收折关节组与前脚支架两侧的后端枢接。
本实用新型的婴童三轮车前轮组收折机构，可使前轮组于支撑骨架收折时通过连杆的连动而往后枢转一段距离，因此在收折后能更贴近两后轮，使整体所占用的空间更小，可有效降低婴童三轮车产品的储运成本，并使婴童三轮车在折收后更容易放进汽车的后行李箱。

具体实施方式
如图1至图5所示，为一依据本实用新型的婴童三轮车前轮组收折机构实施例，至少包括一支撑骨架10、一前轮组12 及一连杆16。
其中支撑骨架10还包括一前脚支架1、一后脚支架2、一上支架3、一对座支架4、一对枢耳31以及一对收折关节组5所组接而成，可藉由锁定收折关节组5而保持于一展开状态100，及释放两收折关节组5而折收至一收折状态200。
在上支架3的上端可设一握持部32供使用者抓握，以利推动婴童三轮车进行慢跑。上支架3的两侧靠近前端处藉由枢耳31与后脚支架2两侧的上端枢接而可形成一省力杠杆机构的支点，两侧的端部并藉由两收折关节组5与前脚支架1两侧的后端枢接。
后脚支架2两侧的下端可90度回转地分别套接一后轮组21，此后轮组21包括一后轮座23并且轴接一后轮22。两座支架4以前端和前脚支架1枢接，以后端和后轮座23枢接，而于支撑骨架10收折时，可随前脚支架1移动而牵动后轮座23，使后轮22从原本朝前滚动的方向20朝一侧旋转90度而到达一打横的方向30。藉此使婴童三轮车于支撑骨架10处于收折状态200时所占的空间更小。
两座支架4连动于前脚支架1与后脚支架2之间。由于两枢耳31装设于后脚支架2两侧的上端；当两收折关节组5 释放时，上支架3得以枢耳31为支点产生杠杆的省力作用抬升两收折关节组5，前脚支架1因重力作用而被动地沿两收折关节组5枢转，并同时经由两座支架4连动后脚支架2，使前脚支架1与后脚支架2得以彼此靠合而成为收折状态200。
本实施例的前轮组12可包括一前轮座13、一前叉轮臂15及一前轮14。在连杆16的后端可固接一横杆17，藉由横杆17的两端分别与两座支架4枢接。前轮座13可朝后掀动地枢接于前脚支架1下端的枢接座11并经由连杆16与支撑骨架10连动。当支撑骨架10折收时，前轮组12除了随着前脚支架1靠近后脚支架2，并经由连杆16牵动而使整个前轮组12可进一步地朝后枢转而更接近后脚支架2，从而更贴近两后轮22之间，以进一步地缩小婴童三轮车收折时所占的空间。
前轮组12的前叉轮臂15轴接于前轮座13下方，可连同前轮14相对于前轮座13左、右自由地回转，因此在支撑骨架10折收时，可手动回转前轮14，以使前轮14可选择停留于两后轮22之间的空隙(如图6所示)，亦可使前轮14平行或重迭于两后轮22之间(如图4与图5所示)，藉此提供不同安置前轮的方式。
