在本申请中，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，或成一体；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或两个元件的相互作用关系。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申请中的具体含义。
实施例1
参照图1至图6所示，本申请实施例1提供一种开合结构，该开合结构包括活动件连接部10、固定件连接部20和弹簧40，活动件连接部10相对于固定件连接部20转动设置，弹簧40包括交叉部403和扭转部405，交叉部403和扭转部405相配合，而且弹簧40的交叉部403在自由状态下的开角不等于其安装于固定件连接部20与活动件连接部10之间的安装夹角，使得弹簧40的交叉部403受力安装于固定件连接部20与活动件连接部10之间，由此交叉部403与扭 转部405配合产生的扭力作用使得活动件连接部10在无人力干预的情况下不会发生自行旋转或复位。
基于本实施例的情况下，弹簧40包括卡接部401，活动件连接部10包括与弹簧40的卡接部401相适配的弹簧卡槽102，弹簧卡槽102被配置为用于容纳卡接部401，弹簧40通过卡接部401安装在弹簧卡槽102内。
还有弹簧40包括孔接部402，固定件连接部20包括与弹簧40的孔接部402相适配的弹簧卡孔203，弹簧40的孔接部402容纳于弹簧卡孔203内，在本实施例中，弹簧卡孔203的孔道尺寸设置为使孔接部402在运动过程中不会脱出。
可选的，弹簧40的孔接部402也可通过设置限位销、螺母等方式固定设置于弹簧卡孔203内，以达到孔接部402在运动过程中不会脱出弹簧卡孔203的效果。
可选地，也可通过其他方式来实现弹簧40的孔接部402的固定，本申请不以此为限制。
继续参照图3所示，扭转部405的大体结构呈圆弧状，如此使得弹簧40的卡接部401呈一定弧度的弯折形成弹簧40的交叉部403，扭转部405与交叉部403相配合。
继续参照图6所示，另一方面弹簧40的交叉部403在自由状态下的开角不等于活动件连接部10在相对于固定件连接部20进行旋转时的旋转夹角，如此在活动件连接部10相对于固定件连接部20进行旋转时，弹簧40产生的扭力作用，使得活动件连接部10受力，能够使其停留在其旋转到的任意位置，不会产生复位现象。
本申请弹簧40的交叉部403在自由状态下的开角是指弹簧40的交叉部403在无受力情况(自由状态)下呈现的开叉角度θ，见图4所示。
可选的，开合结构包括转轴30，活动件连接部10包括与转轴30相适配的第一轴孔101，固定件连接部20包括与转轴30相适配的第二轴孔202，第一轴孔101和第二轴孔202同轴设置，转轴30穿设于第一轴孔101与第二轴孔202内，实现活动件连接部10相对于固定件连接部20的转动。
可选的，固定件连接部20包括腔体201，第二轴孔202和弹簧卡孔203贯通腔体201，用于容纳弹簧40，可选地，固定件连接部20的腔体201是非必需的，可将第二轴孔202和弹簧卡孔203直接设置于固定件上，本申请不以此为限制。
实施例2
本实施例提供了另一种开合结构，其包括上述实施例1中的各个部件，且相同的部件采用相同的附图标记，该实施例在这里不再赘述。然而不同的是，参照图7所示，本实施例中弹簧40包含的扭转部405的大体结构呈螺旋状，可选的，扭转部405的螺旋圈数为多圈，如此使得弹簧40的卡接部401在经过多圈螺旋后弯折形成弹簧40的交叉部403，扭转部405与交叉部403相配合。
