本发明目的的实现、功能特点及优点将结合实施例,参照附图做进一步说明。

在本发明中,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本发明中的具体含义。
参照图1至图3所示,本发明实施例提供了一种转轴装置,用于可折叠电子装置,该转轴装置包括承接件10、第一转动连接件20、第二转动连接件30、摩擦机构40及保持机构50。
具体的,第一转动连接件20包括第一转轴201及第一支架202,第一转轴201可枢
转地连接于承接件10,第一支架202固定连接于第一转轴201,例如图1至图3所示示例中第一支架202通过销钉203固定在第一转轴201上。也就是说,第一转轴201相对于承接件10转动,而第一支架202则可以随所述第一转轴201的转动而转动,该第一支架202用于连接可折叠电子装置的第一机体(例如主机本体),如此,第一机体可以随第一支架202转动而转动。
第二转动连接件30包括第二转轴301及第二支架302,第二转轴301可枢转地连接于承接件10且与第一转轴201相对,第二支架302固定连接于第二转轴301,例如图1至图3所示示例中,第二支架302通过销钉303固定在第二转轴301上。也就是说,第二转轴301可以相对于承接件10转动,而第二支架302则可以随第二转轴301的转动而转动。由于第一转轴201与第二转轴301相对,所以当第一支架202和/或第二支架302转动时,第一支架202与第二支架302彼此靠近或远离。该第二支架302具体用于连接可折叠电子装置的第二机体(例如显示器),如此,电子产品的第一机体和第二机体之间可以随第一支架202与第二支架302转动远离而打开,或随第一支架202与第二支架302转动靠近而折合在一起。
摩擦机构40包括第一主动齿轮401、第二主动齿轮402及至少一个从动齿轮,第一主动齿轮401固设于第一转轴201上,第二主动齿轮402固设于第二转轴301上,至少一个从动齿轮可枢转设置于承接件10上且与第一主动齿轮401及第二主动齿轮402分别啮合。由于第一主动齿轮401、至少一个从动齿轮及第二主动齿轮402之间彼此啮合,所以当第一支架202和/或第二支架302转动时,第一转轴201、第二转轴301分别带动第一主动齿轮401及第二主动齿轮402转动,第一主动齿轮401及第二主动齿轮402再进一步带动上述的至少一个齿轮转动,如此,通过齿轮之间的啮合可以增大第一支架202与第二支架302之间转动时的摩擦力,该摩擦力为阻力,所以,可以提高第一支架202与第二支架302打开状态时的稳定性。
保持机构50包括套筒501、滑套502及弹性阻尼机构,套筒501套接在第二转轴301并与承接件10周向固定,也就是说第二转轴301与套筒501之间是可以相对转动的,而套筒501与承接件10之间是不能相对转动。套筒501的圆周表面设有螺旋滑道,滑套502可沿平行于第二转轴301的方向滑动地套设于第二支架302,且滑套502上设有***螺旋滑道内的凸起5021,以使第二支架302转动时滑套502相对于第二支架302滑动,本实施例中,螺旋滑道为半圈,当第二支架302转动时,凸起5021在螺旋滑道内滑动,而滑套502则在第二支架302上滑动,当凸起5021由螺旋滑道的一端滑动到
另一端时,滑套502对应从第二支架302上的一个位置滑动至另一个位置,而第二支架302与第一支架202可由打开状态变为闭合状态或者由闭合状态变为打开状态。弹性阻尼机构连接于滑套502与第二支架302之间,以提供滑套502滑动时的阻力,当第二支架302转动时,第二支架302带动第二转轴301转动,同时,滑套502上的凸起5021在套筒501上的螺旋滑道内滑动,并迫使滑套502在第二支架302上滑动,而弹性阻尼机构提供滑套502滑动时的阻力,也就是阻止滑套502运动,如此,即可增大第二支架302转动过程中的阻力。
根据本发明提供的转轴装置及具有该转轴装置的可折叠电子装置,一方面,通过摩擦机构40增大第一支架202和第二支架302转动过程的摩擦力,另一方面,保持机构50中的滑套502随第二支架302转动而滑动,且滑套502滑动时,滑套502上的凸起5021在螺旋滑道内滑动,如此,可以增大第二支架302转动中的阻力;再一方面,保持机构50中的弹性阻尼机构可以提供滑套502滑动的阻力,如此,可以使第二支架302保持与第一支架202呈打开状态,藉此,本发明具有较大的转动摩擦力,具有良好的转动连接效果,长期使用摩擦力基本不会衰减,使用寿命长,连接稳固可靠。
在本发明的一个实施例中,第一转轴201至少包括第一轴段2011及第二轴段2022,第一轴段2011具有两相对的固定平面及贯穿两固定平面的通孔,第一支架202通过穿过销钉203的通孔固定在第一转轴201上。第二轴段2022包括两相对的限位平面及两相对的圆弧面,第一主动齿轮401通过非圆形匹配孔套设在第二轴段2022上,且与相对的两限位平面周向相对固定,而承接件10通过圆形孔套设在第二轴段2022上,且与相对的两圆弧面可相对转动。
对应的,第二转轴301包括第三轴段3011、第四轴段及第五轴段3012,第三轴段3011具有两相对的固定平面及贯穿两固定平面的通孔,第二支架302通过穿过该通孔的销钉203与第二转轴301固定。第四轴段为圆柱形,套筒501套接在第四轴段,且与第四轴段之间可相对转动。第五轴段3012具有两相对的限位平面及两相对的圆弧面,第二主动齿轮402通过非圆形匹配孔套设在第五轴段3012上,且与第五轴段3012周向固定,而承接件10则通过圆形孔套设在第五轴段3012上,且与相对的两圆弧面可相对转动。如此,可以简化第一转轴201、第二转轴301、第一支架202、第二支架302、摩擦机构40等之间的连接结构,同时,可以提高结构强度,也利于装配。
在本发明的一个实施例中,弹性阻尼机构包括弹簧503及联动件504,联动件504包含中心体5041及自中心体5041延伸形成的第一转动臂5042及与第一转动臂5042形
成一夹角的第二转动臂5043。中心体5041可枢转连接于所述第二支架302,第二支架302上设有第一滑槽3021及第二滑槽3022,第一转动臂5042的自由端穿设有第一销轴505,第一销轴505可滑动地设置于第一滑槽3021,第二转动臂5043的自由端穿设有第二销轴506,第二销轴506可滑动地设置于第二滑槽3022。弹簧503的一端与第一转动臂5042的自由端固定连接,弹簧503的另一端与滑套502的固定连接。如此,当第二支架302沿一个方向(例如顺时针)转动时,滑套502在第二支架302上向一侧滑动,由于弹簧503与滑套502连接,所以,滑套502向第二支架302的一侧运动时,弹簧503被拉伸,第一转动臂5042转动,第一销轴505在第一滑槽3021内滑动,而第二转动臂5043与第一转动臂5042联动,第第二销轴506则在第二滑槽3022内滑动。而当第二支架302沿另一个方向(例如逆时针)转动时,滑套502在第二支架302上向另一侧滑动,由于弹簧503与滑套502连接,所以,滑套502向第二支架302的另一侧运动时,弹簧503逐渐收缩,第一转动臂5042转动,第一销轴505在第一滑槽3021内滑动,而第二转动臂5043与第一转动臂5042联动,第二销轴506则在第二滑槽3022内滑动。这种结构设计,可以使得第二支架302转动地阻力大大提高,需要施加较大的扭转力矩才可以将第二支架302与第一支架202打开,在打开后的打开状态,也需要施加较大的扭转力矩才能够将第二支架302与第一支架202闭合,如此,可以提高第一支架202与第二支架302打开状态时的稳定性。
可选地,在本发明的一个示例中,从动齿轮包括第一从动齿轮403及第二从动齿轮,第一从动齿轮403与第一主动齿轮401及第二从动齿轮啮合,第二从动齿轮与第二主动齿轮402啮合。当第一支架202和/或第二支架302转动时,第一转轴201、第二转轴301分别带动第一主动齿轮401及第二主动齿轮402转动,第一主动齿轮401及第二主动齿轮402再进一步带动上述的第一从动齿轮403及第二从动齿轮转动,如此,可使得第一支架202与第二支架302之间转动时的摩擦力更大。
在本发明的一个实施例中,承接件10包括第一承接板101及第二承接板102,第一转轴201及第二转轴301均依次穿过第一承接板101及第二承接板102,第一主动齿轮401、第二主动齿轮402位于第一承接板101与第二承接板102之间。具体而言,第一承接板101与第二承接板102之间间隔开来,如此,可以提高整个转轴装置的结构牢固性和可靠性。
在本发明的一个优选实施例中,第一转轴201上设有第一转动阻尼机构60,第一转动阻尼机构60套设于第一转轴201上,以提供第一转轴201与所述承接件10之间相对
转动的阻力。第二转轴301上设有第二转动阻尼机构70,第二转动阻尼机构70套设于第二转轴301上,以提供第二转轴301与所述承接件10之间相对转动的阻力。
更为具体的,在本发明的一个示例中,第一转动阻尼机构60包括依次套设在所述第一转轴201上的第一垫片601、第一弹性片602、第二垫片603及螺纹连接在所述第一转轴201上用于将所述第一垫片601、第一弹性片602、第二垫片603与所述承接件10彼此压紧的第一锁紧螺母604。具体的,例如图1所示示例中,第一垫片601、第二垫片603可通过非圆形匹配孔套接在第一转轴201的第二轴段2022上且与限位平面周向固定,而第一弹性片602通过圆形孔套设在第一转轴201的第二轴段2022上,且与圆弧面可相对转动。如此,通过第一锁紧螺母604可以提供轴向的压力,使第一垫片601、第二弹性片702、第二垫片603与承接件10彼此压紧,在第一转轴201转动时,第一垫片601、第一弹性片602、第二垫片603及承接件10彼此之间的接触面产生摩擦阻力。
第二转动阻尼机构70包括依次套设在所述第一转轴201上的第三垫片701、第二弹性片702、第四垫片703及螺纹连接在所述第一转轴201上用于将所述第三垫片701、第二弹性片702、第四垫片703与所述承接件10彼此压紧的第二锁紧螺母704。具体的,例如图1所示示例中,第三垫片701、第四垫片703可通过非圆形匹配孔套接在第一转轴201的第五轴段3012且与限位平面周向固定,而第二弹性片702可通过圆形孔套设在第二转轴301的第五轴段3012上,且与圆弧面可相对转动。如此,通过第二锁紧螺母704可以提供轴向的压力,使第三垫片701、第二弹性片702、第四垫片703与承接件10彼此压紧,在第二转轴301转动时,第三垫片701、第二弹性片702、第四垫片703及承接件10彼此之间的接触面产生摩擦阻力。
更为有利的,在本发明的一个示例,还包括一定位件80,该定位件80的一端套接在第一转轴201且位于第二垫片603与第一锁紧螺母604之间,定位件80的另一端套接在第二转轴301上且位于第四垫片703与第二锁紧螺母704之间。如此,该定位件80可增强承接件10与第一转轴201、第二转轴301连接的可靠性。
在本发明的又一实施例中,承接件10还包括一可枢转地套设在第一转轴201及第二转轴301上的垫板103,垫板103位于第一承接板101与第二承接板102之间,且垫板103与第一承接板101之间具有套设并周向固定在第一转轴201、第二转轴301上的第五垫片104;第一主动齿轮401、第二主动齿轮402及至少一个从动齿轮位于垫板103与第二承接板102之间,如此,可以增强结构的牢固性。
更为有利的,在本发明的一个优选实施例中,垫板103与第一主动齿轮401和第二
主动齿轮402的接触面设有用于增大转动时的摩擦力的增摩结构。例如,在第一主动齿轮401和第二主动齿轮402的下表面设有摩擦凸起5021,而在垫板103的上表面设有凹坑,如此,在转动过程中,垫板103与第一主动齿轮401和第二主动齿轮402的接触面的摩擦阻力可以进一步增大。
本发明还提供了一种可折叠电子装置,包括第一机体、第二机体及如上述实施例所述的转轴装置。所述第一机体与所述转轴装置的第一支架202固定连接,所述第二机体与所述转轴装置的第二支架302固定连接,以使所述第一机体与第二机体可随所述第一支架202及第二支架302的相对转动而打开或闭合。
根据本发明提供的可折叠电子装置,由于采用上述实施例所述的转轴装置,一方面,通过摩擦机构40增大第一支架202和第二支架302转动过程的摩擦力,另一方面,保持机构50中的滑套502随第二支架302转动而滑动,且滑套502滑动时,滑套502上的凸起5021在螺旋滑道内滑动,如此,可以增大第二支架302转动中的阻力;再一方面,保持机构50中的弹性阻尼机构可以提供滑套502滑动的阻力,如此,可以使第二支架302保持与第一支架202呈打开状态,藉此,本发明具有较大的转动摩擦力,具有良好的转动连接效果,长期使用摩擦力基本不会衰减,使用寿命长,连接稳固可靠。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中,对上述术语的示意性表述不一定指的是相同的实施例或示例。而且,描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
