背景技术
随着技术的发展，电子设备的发展也越来越快速，同时，用户对电子设备的要求也越来越高。目前柔性屏幕也广泛地应用于电子设备，进而形成折叠式的电子设备。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合图1至图10，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。
本申请实施例提供的电子设备，包括第一壳体100、第二壳体200、屏幕组件300、轴组件400和连杆机构500。第一壳体100和第二壳体200为基础结构件，可以为电子设备中的各零部件提供安装基础。
参照图1至图6，第一壳体100和第二壳体200通过轴组件400转动配合，进而使得电子设备可以通过第一壳体100和第二壳体200相对转动实现电子设备折叠或展开。
参照图3和图4，屏幕组件300覆盖于第一壳体100和第二壳体200一侧表面。示例性地，屏幕组件300包括第一段、第二段和连接段，连接段位于第一段和第二段之间，且连接段分别与第一段和第二段相连。第一段设置于第一壳体100，第二段设置于第二壳体200。示例性地，屏幕组件300的连接段与轴组件400相对。
示例性地，第一壳体100可以相对第二壳体200在第一位置和第二位置之间转动。参照图3和图4，在第一壳体100相对第二壳体200在第一位置的情况下，屏幕组件300的显示面位于同一平面，实现电子设备展开，即电子设备处于展开状态。参照图2和图5，在第一壳体100相对第二壳体200在第二位置的情况下，第一壳体100和第二壳体200相互折叠，即电子设备处于折叠状态。示例性地，在电子设备处于折叠状态的情况下，第一壳体100靠近屏幕组件300的一侧叠置于第二壳体200靠近屏幕组件300的一侧，进而实现电子设备内折。
参照图2至图5，连杆机构500包括第一连杆510和第二连杆520，第一连杆510与第二连杆520交叉设置，且第一连杆510与第二连杆520在交叉部511转动配合。第一连杆510的第一端与第一壳体100相连，第二连杆520的第一端与第二壳体200相连，第一连杆510的第二端和第二连杆520的第二端均支撑于屏幕组件300。在电子设备折叠的过程中，第一壳体100和第 二壳体200带动第一连杆510和第二连杆520相对转动，第一连杆510的第二端和第二连杆520的第二端相互远离，屏幕组件300至少部分内陷于第一连杆510的第二端和第二连杆520的第二端之间的间隙。
上述实施例中，电子设备在折叠的过程中，第一壳体100和第二壳体200可以分别带动第一连杆510和第二连杆520转动。并且，第一连杆510的第二端与第二连杆520的第二端之间形成的间隙组件增加，使得屏幕组件300的冗余部分可以容纳于第一连杆510的第二端与第二连杆520的第二端之间形成的间隙内。因此上述实施例所述的电子设备可以避免屏幕组件300在电子设备折叠的过程中受压，避免屏幕组件300受压损坏。
参照图4和图5，在电子设备展开的过程中，第一连杆510和第二连杆520相对转动，并支撑屏幕组件300靠近轴组件400的一侧，使得屏幕组件300中与轴组件400相对部分可以向远离轴组件400的方向移动，辅助屏幕组件300展开。
上述实施例中，通过第一连杆510和第二连杆520形成容纳屏幕组件300冗余部分的间隙，可以增加屏幕组件300弯折后弯折部分的半径，可以消除或减弱屏幕组件300弯折部分的折痕。并且第一连杆510和第二连杆520可以在电子设备展开的过程中，支撑屏幕组件300并辅助屏幕组件300展开。
参照图2至图5，第一壳体100、第二壳体200和轴组件400在轴组件400靠近屏幕组件300的一侧形成沿轴组件400的容纳槽600。在电子设备展开的情况下，第一连杆510的第二端和第二连杆520的第二端至少部分位于容纳槽600，且第一连杆510的第二端和第二连杆520的第二端支撑于屏幕组件300与容纳槽600相对的部分。
参照图4和图5，在电子设备展开的过程中，第一壳体100和第二壳体200相对转动，并带动第一连杆510和第二连杆520相对转动。在第一连杆510和第二连杆520相对转动的过程中，第一连杆510的第二端和第二连杆520的第二端相互靠近，即第一连杆510的第二端与第二连杆520的第二端 之间的夹角减小，同时，第一壳体100和第二壳体200可拉动屏幕组件300中冗余部分，进而使得屏幕组件300内陷于第一连杆510的第二端与第二连杆520的第二端之间间隙的冗余部分可以逐渐展开。在电子设备完全展开的情况下，屏幕组件300与轴组件400相对的部分可以通过第一连杆510和第二连杆520支撑，以避免屏幕组件300内陷于容纳槽600内。
参照图9和图10，连杆机构500还包括第一支撑件570和第二支撑件580，第一支撑件570与第一连杆510的第二端相连，第二支撑件580与第二连杆520的第二端相连。在所述电子设备展开的情况下，第一支撑件570和第二支撑件580均支撑于屏幕组件300与容纳槽600相对的部分。
示例性地，第一支撑件570和第二支撑件580可以为支撑板。在电子设备展开的过程中，第一连杆510和第二连杆520相对转动，进而带动第一支撑件570和第二支撑件580转动。进一步地，在电子设备展开的情况下，第一支撑件570和第二支撑件580均可以与第一壳体100和/或第二壳体200靠近屏幕组件300的一侧齐平，进而使得第一支撑件570和第二支撑件580可以支撑屏幕组件300。
上述实施例中，第一支撑件570和第二支撑件580可以在电子设备展开的情况下对屏幕组件300中与容纳槽600相对的部分进行支撑，以避免屏幕组件300在使用过程中受力凹陷，提高用户体验。
参照图4和图5，交叉部511距离第一连杆510的第一端的距离为第一距离，交叉部511距离第一连杆510的第二端的距离为第二距离，第一距离大于第二距离。交叉部511距离第二连杆520的第一端的距离为第三距离，交叉部511距离第二连杆520的第二端的距离为第四距离，第三距离大于第四距离。第一连杆510和第二连杆520相对转动的过程中，第一距离大于第二距离，第三距离大于第四距离，能够有效减小第一壳体100和第二壳体200带动第一连杆510和第二连杆520转动受到的阻力，使得电子设备在折叠或展开的过程中更加顺畅。
一种可选地实施例中，第一距离与第三距离相等，第二距离与第四距离相等。示例性地，第一连杆510和第二连杆520对称设置。第一连杆510和第二连杆520可以设置为直杆，也可以设置为弯杆。示例性地，第一连杆510的第二端和第二连杆520的第二端均可以设置有支撑部，以通过支撑部支撑于第一支撑件570和第二支撑件580远离屏幕组件300的一侧。
参照图6至图8，连杆机构500包括第一弹性件530和第二弹性件540，第一弹性件530设置于第一连杆510的第二端和第二连杆520的第二端之间，且沿屏幕组件300的延伸方向延伸。第二弹性件540设置于第一弹性件530和交叉部511之间，且沿垂直于屏幕组件300的方向延伸。在电子设备展开的过程中，第一弹性件530逐渐收缩，且第二弹性件540逐渐伸长。在电子设备折叠的过程中，第一弹性件530逐渐伸长，第二弹性件540逐渐收缩。示例性地，第一弹性件530和第二弹性件540均为螺旋弹簧。
参照图4在电子设备展开的情况下，第一弹性件530处于压缩的状态，进而使得第一弹性件530不易弯曲。在电子设备折叠的过程中，第一弹性件530被拉伸，进而使得第一弹性件530在第二弹性件540的拉动下凸向第一连杆510和第二连杆520之间的间隙，进而形成容纳屏幕组件300冗余部分的凹槽。
在电子设备展开的过程中，第一弹性件530收缩，进而使得第一弹性件530的抗弯性能增加，并拉动第二弹性件540伸长，第一弹性件530形成的容纳屏幕组件300冗余部分的凹槽深度减小，进而推动位于第一连杆510和第二连杆520之间间隙的屏幕组件300向远离交叉部511的方向移动。
上述实施例中，第一弹性件530和第二弹性件540可以辅助第一连杆510和第二连杆520之间间隙内的屏幕组件300向外伸展。
参照图4至图10，轴组件400包括第一转轴410、第二转轴420和连接件430，第一转轴410和第二转轴420平行设置，且第一转轴410和第二转轴420通过连接件430相连。第一转轴410与第一壳体100相连，第二转轴 420与第二壳体200相连。示例性地，连接件430上设置有第一安装孔和第二安装孔，第一安装孔和第二安装孔平行设置。进一步地，第一转轴410设置于第一安装孔，并与第一安装孔转动配合；第二转轴420设置于第二安装孔，并与第二安装孔转动配合。
上述实施例中，第一转轴410和第二转轴420平行设置，进而使第一壳体100和第二壳体200分别围绕两个相互平行的轴线转动，进而使得第一壳体100和第二壳体200相互避让的空间增加，以避免第一壳体100和第二壳体200在电子设备展开或折叠的过程中相互干扰。进一步地，可以根据第一壳体100和第二壳体200的厚度调节第一转轴410和第二转轴420之间的间距。具体的，第一转轴410和第二转轴420之间的间距越大，第一壳体100和第二壳体200在轴组件400处形成的相互避让的空间越大。进而需要根据第一壳体100和第二壳体200的厚度选择第一转轴410和第二转轴420之间的间距。为此，实施例不限定第一转轴410和第二转轴420之间的间距。
一种可选的实施例中，第一转轴410与第二转轴420之间的间距为第五距离，第一转轴410距离第一壳体100中远离屏幕组件300的第一段的一侧的距离为第六距离。第二转轴420距离第二壳体200中远离屏幕组件300的第二段的一侧的距离为第七距离。第五距离不小于第六距离与第七距离之和，进而在电子设备外折的情况下，第一壳体100和第二壳体200能够更好地贴合，以减小电子设备叠合后的厚度，提高电子设备折叠后的舒适度。
参照图4至图10，第一连杆510的第一端与第一壳体100转动相连，且第一连杆510的第一端相对第一转轴410偏心设置。第二连杆520的第一端与第二壳体200转动相连，且第二连杆520的第一端相对第二转轴420偏心设置。
需要说明的是，第一连杆510的第一端相对第一转轴410偏心设置是指第一连杆510相对第一壳体100转动的中心与第一壳体100相对第一转轴410转动的中心不重合。同理，第二连杆520的第一端相对第二转轴420偏心设 置，是指第二连杆520相对第二壳体200转动的中心与第二壳体200相对第二转轴420转动的中心不重合。
示例性地，在电子设备展开的情况下，第一壳体100和第一连杆510的连接处距离第二壳体200的距离为第八距离。在电子设备折叠的情况下，第一壳体100和第一连杆510的连接处距离第二壳体200的距离为第九距离，第八距离小于第九距离。进一步地，在电子设备展开的情况下，第二壳体200和第二连杆520的连接处距离第一壳体100的距离为第十距离。在电子设备折叠的情况下，第二壳体200和第二连杆520的连接处距离第一壳体100的距离为第十一距离，第十距离小于第十一距离。
在电子设备折叠的过程中，第一壳体100相对第一转轴410转动，第二壳体200相对第二转轴420转动，进而带动第一连杆510的第一端和第二连杆520的第一端相互远离。在电子设备展开的过程中，第一壳体100相对第一转轴410转动，第二壳体200相对第二转轴420转动，进而带动第一连杆510的第一端和第二连杆520的第一端相互靠近。
需要说明的是，第一连杆510的第一端与第一壳体100转动相连，可以是第一连杆510的第一端与第一壳体100直接转动配合，还可以是第一连杆510的第一端与第一壳体100间接转动配合。
一种可选的实施例中，第一壳体100和第一连杆510上均设置有铰接孔，以使第一壳体100和第一连杆510可以通过轴转动实现转动配合。
另一种可选的实施例中，连杆机构500还包括第三连杆550，第三连杆550与第一壳体100和/或第一转轴410相连，且第三连杆550可随第一壳体100绕第一转轴410转动，第一连杆510的第二端与第三连杆550转动相连。可选地，第三连杆550可以与第一转轴410和/或第一壳体100固定相连。示例性地，电子设备折叠的过程中，第一壳体100和/或第一转轴410带动第三连杆550围绕第一转轴410转动，进而带动第一连杆510的第一端向远离第二壳体200的方向移动。
同理，连杆机构500还包括第四连杆560，第四连杆560与第二壳体200和/或第二转轴420相连，且第四连杆560可随第二壳体200绕第二转轴420转动，第二连杆520的第二端与第四连杆560转动相连。可选地，第二连杆520与第二壳体200的配合关系与第一连杆510和第一壳体100之间的配合关系相同。为此，本说明书不再进一步阐述第二连杆520与第二壳体200的配合关系。
参照图5、图7和图8，连接件430上开设有导轨431，导轨431由连接件430靠近屏幕组件300的一侧向连接件430远离屏幕组件300的一侧设置。交叉部511与导轨431滑动配合，且交叉部511可沿导轨431移动。示例性地，导轨431为设置于连接件430上的导向槽，交叉部511至少部分位于导向槽内，且交叉部511可沿导向槽滑动。
一种可选的实施例中，第一连杆510和第二连杆520通过连接轴转动配合。示例性地，连接轴至少部分凸出于第一连杆510和/或第二连杆520，且凸出于第一连杆510和/或第二连杆520的连接轴至少部分位于导向槽内，以使第一连杆510和第二连杆520的交叉部511可以通过连接轴与导向槽滑动配合。
上述实施例中，电子设备在折叠的过程中，第一壳体100和第二壳体200相对转动，并带动第一连杆510和第二连杆520向远离屏幕组件300的方向移动。电子设备在展开的过程中，第一壳体100和第二壳体200相对转动，并带动第一连杆510和第二连杆520向靠近屏幕组件300的方向移动。该方案可以通过第一连杆510和第二连杆520向远离屏幕组件300的方向移动，使得电子设备在折叠状的情况下可以形成更大的容纳屏幕组件300冗余部分的空间。
一种可选地实施例中，电子设备包括第一齿轮和第二齿轮，第一齿轮和第二齿轮啮合。第一齿轮与第一壳体100相连，且第一壳体100可带动第一齿轮相对连接件430转动。第二齿轮与第二壳体200相连，且第二壳体200 可带动第二齿轮相对连接件430转动。示例性地，第一齿轮和第二齿轮可以为弧形齿段。示例性地，第一齿轮可以固定设置于第一壳体100上，第二齿轮固定设置于第二壳体200上。第一齿轮和第二齿轮啮合，使得第一壳体100和第二壳体200可以同步转动，提升用户体验。
参照图4和图5，屏幕组件300包括柔性屏310和柔性支撑件320，柔性支撑件320设置于柔性屏310远离显示面的一侧，且柔性支撑件320与轴组件400相对。可选地，柔性支撑件320的两侧可以分别与第一壳体100和第二壳体200相连。该实施例中，柔性支撑件320可以避免连杆机构500直接支撑于柔性屏310上，达到保护柔性屏310的目的。
