 附图说明
图1为本发明一种利用阻尼力达到悬停的运动铰链的闭合状态的立体结构示意图。
图2为本发明的一种利用阻尼力达到悬停的运动铰链的爆炸结构示意图。
图3为本发明的一种利用阻尼力达到悬停的运动铰链的悬停状态结构示意图。
 本发明的最佳实施方式
以下结合附图对本发明的结构做进一步说明。
参照图1至图3，一种利用阻尼力达到悬停的运动铰链包括有铰链主体固定板1，与铰链主体固定板铰接的门板安装板2，运动铰链还包括有使门板安装板相对铰链主体固定板成角度悬停的悬停机构3，悬停机构3包括有连接门板安装板与连接主体固定板的连杆31，连杆的一端与门板安装板铰接，连杆上设有导向滑道32，悬停机构还包括有设于铰链主体固定板上的与导向滑道配合的滚轮33，以及拉动连杆在滚轮上滚动使门板闭合或悬停的阻尼机构34，导向滑道32包括有设于导向滑道起始端的与滚轮相切的用于使门板自动关闭的自动关闭滑道321，以及与自动关闭滑道连通的弧形的悬停滑道322，自动关闭滑道的起始端为门板锁紧位置，悬停滑道与自动关闭滑道的连接处为第一悬停位置，悬停滑道的末端为门板最大限度打开位置，在自动关闭滑道，弹簧对连杆的拉力和滚轮对连杆的阻尼力的合力大于门板对连杆的拉力，在悬停滑道，弹簧对连杆的拉力和滚轮对连杆的阻尼力的合力等于门板对连杆的拉力。本实施例中，当门板打开到第一悬停位置时，导向滑道上与滚轮相切的位置为第一滑道的末端位置同时也是悬停滑道的起始端；在自动关闭滑道，弹簧对连杆的拉力和滚轮对连杆的阻尼力的合力大于门板对连杆的拉力，因此在自动关闭滑道范围内，门板能够自动关闭。当门板打开到最大位置时，在滚轮接触点处确定悬停滑道的末端，悬停滑道的起点和末端之间通过弧线连接。可以根据阻尼机构的拉力以及门板的重量来调整悬停滑道弧线的形状，调整弹簧对连杆的拉力和滚轮对连杆的阻尼力的合力，使弹簧对连杆的拉力和滚轮对连杆的阻尼力的合力等于门板对连杆的拉力，从而达到门板悬停的目的。本实施例中，悬停滑道上设有T形齿状缺口3221。从而增加悬停滑道与连杆之间的阻尼力。具体实施时，可以根据需要设置门板与竖直方向的夹角为锐角的范围内自动关闭，比如门板关闭时，门板与竖直方向的夹角为-2度到0度之间。具体实施时，可以设置合适的悬停角度范围。比如门板最大角度悬停时，门板与竖直方向的夹角为88到90度之间。本发明的利用阻尼力达到悬停的运动铰链的连杆在自动关闭滑道内带动门板自动关闭，在悬停滑道内可以悬停，可以根据需要设置自动关闭的角度和门板悬停开启的角度，从而使用方便，工作效率高。
本实施例中，铰链主体固定板1上设有U形槽11，U形槽的底部开设有用于上下连杆运动限位的限位槽12，连杆穿过限位槽与门板安装板铰接。连杆在运动的过程中，限位槽12可以限定连杆运动的最高位置和最低位置，从而可以配合自动关闭滑道和悬停滑道的结构来进一步限位门板的打开范围。
本实施例中，阻尼机构34为一端与铰链主体固定板固定连接，另一端与连杆固定连接的弹簧。门板打开时，门板带动连杆伸长，弹簧被连杆拉动伸长，在悬停滑道内，门板重量对连杆的拉力与弹簧对连杆的拉力，以及滚轮与连杆之间的阻尼力达到一个平衡，门板悬停。在自动关闭滑道内，弹簧的对连杆的拉力和滚轮对连杆的阻尼力的合力大于门板重量对连杆的拉力，门板自动关闭。
本实施例中，门板安装板2上设有U形的安装槽21，安装槽的连杆通过连杆转轴转动设于安装槽内侧壁上。从而能够使连杆与门板安装板之间铰接稳定。
虽然结合附图对本发明的具体实施方式进行了详细地描述，但不应理解为对本发明的保护范围的限定。在权利要求书所描述的范围内，本领域技术人员不经创造性劳动即可做出的各种修改和变形仍属于本发明的保护范围。
