为使本申请实施例的目的、技术方案和优点更加清楚，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做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。
实施例1
图1为本申请实施例提供的折叠模组的爆炸图；图2为本申请实施例提供的折叠模组展开时的结构示意图；图3为本申请实施例提供的折叠模组展开150°时的结构示意图；图4为本申请实施例提供的折叠模组展开90°时的结构示意图；图5为本申请实施例提供的折叠模组展开30°时的结构示意图；图6为本申请实施例提供的折叠模组折叠时的结构示意图；图7为本申请实施例提供的折叠式电子设备的结构示意图。
请参照图1-图7。本实施例提供一种折叠模组1，包括：第一连接部20、第一心轴10、第一驱动环30以及第一弹簧40；第一连接部20上设置有第一轴孔，第一心轴10穿设在第一驱动环30、第一轴孔以及第一弹簧40内；第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，第一凸出部202位于第一弹簧40和第一凹陷部301之间、或者第一凹陷部301位于第一弹簧40和第一凸出部202之间，第一凸出部202嵌入到第一凹陷部301内；第一连接部20转动时，第一凸出部202由第一凹陷部301内滑出。
继续参照图7，具体地，折叠设备上具有可互相折叠的第一支撑件2和第二支撑件3，即第一支撑件2和第二支撑件3可以折叠在一起或者展开；第一连接部20与第一支撑件2连接，相应的第二支撑件3可以与第一心轴10连接，当第一支撑件2和第二支撑件3互相折叠或者展开时，第一支撑件2带动第一连接部20转动，以使第一支撑件2相对于第二支撑件3转动。
本实施例优选地，第一连接部20与第一支撑件2之间的连接方式可以有多中，只要能够保证第一支撑件2和第二支撑件3之间可以顺利转动即可；例如：在第一连接部20上设置第一滑柱201，相应的在第一支撑件2上设置有与第一滑柱201配合的第一滑槽，第一支撑件2和第二支撑件3之间相对转动时，第一连接部20绕第一心轴10转动，并且第一滑柱201在第一滑槽内滑动。如此设置，在实现第一连接部20随第一支撑件2转动的同时，也为第一连接部20相对于第一支撑件2的滑动留出余量，以使转动较为顺畅。
进一步地，在第一连接部20上设置两个第一滑柱201，两个第一滑柱201的中心线共线设置；并且，两个第一滑柱201间隔的设置在第一连接部20的两侧，相应的，在第一支撑件2上设置两个第一滑槽，每一第一滑柱201滑设在一个第一滑槽内，将 第一连接部20夹设在两个第一滑槽之间，可以避免第一滑柱201与对应的第一滑槽分离，提高了第一连接部20与第一支撑件2之间的连接稳定性。
本实施例中，第一弹簧40可以为螺旋弹簧，第一心轴10穿设在第一驱动环30、第一轴孔和第一弹簧40内，第一弹簧40可以使第一驱动环30和第一连接部20彼此贴合。以使第一驱动环30和第一连接部20之间的第一凸出部202嵌入到第一凹陷部301内。
值得说明的是，为了避免在使用过程中第一心轴10与第一驱动环30、第一弹簧40以及第一连接部20脱离，可以在第一心轴10靠近两端的侧壁上设置外螺纹，相应的，在第一心轴10靠近两端的位置均设置与外螺纹配合的抵顶螺母，两个抵顶螺母夹设在第一弹簧40、第一驱动环30以及第一连接部20外侧，以实现第一心轴10与第一弹簧40、第一驱动环30以及第一连接部20的连接。
本实施例中第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，示例性的，第一凸出部202可以设置在第一驱动环30朝向第一连接部20的侧壁上，相应的，第一凹陷部301设置在第一连接部20朝向第一驱动环30的侧壁上；或者第一凸出部202设置在第一连接部20朝向第一驱动环30的侧壁上，第一凹陷部301设置在第一驱动环30朝向第一连接部20的侧壁上。
本实施例中，第一弹簧40用于使第一驱动环30和第一连接部20贴合，以使第一凸出部202嵌入到第一凹陷部301内。具体地，第一弹簧40可以直接与第一连接部20连接，即第一连接部20设置在第一驱动环30和第一弹簧40之间，以在第一弹簧40的抵顶下，使第一连接部20与第一驱动环30贴合。
本实施例优选地，合理的设置第一凸出部202和第一凹陷部301的形状和位置，可以在第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202嵌入到第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202滑出至第一凹陷部301外；使第一支撑件2能够保持在展开状态，并且在折叠的过程中提供阻尼力，在第一支撑件2和第二支撑件3展开的过程中提供恢复力，以驱动第一支撑件2和第二支撑件3自动展开。当然合理的设置第一凸出部202和第一凹陷部301的形状和位置，也可以在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202嵌入到第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202滑出至第一凹陷部301外；以使第一支撑件2和第二支撑件3保持在折叠状态，并且在展开的过程中提供阻尼力，在第一支撑件2和第二支撑件3折叠的过程中提供恢复力，以驱动第一支撑件2和第二支撑件3自动折叠。
优选地，可以设置多个第一凹陷部301，多个第一凹陷部301环绕第一心轴10间隔的设置；并且使第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202嵌入到一个第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202嵌入到另一个第一凹陷部301内，以使第一支撑件2和第二支撑件3可以保持在展开状态和折叠状态，并且在刚开始展开和刚开始折叠的过程均提供阻尼力，在即将完全展开和即将完全折叠时提供恢复力，推动第一支撑件2和第二支撑件3完全展开或者完全折叠。
继续参照图1-图6。示例性的，在第一连接部20和第二连接部60的夹角由180 °的展开状态，逐渐折叠时，第一凸出部202逐渐由第一凹陷部301内滑出，此时驱动第一驱动环30沿轴向移动，以压缩第一弹簧40，提供阻尼力，进而阻止第一连接部20和第二连接部60折叠；当折叠至第一连接部20和第二连接部60间的夹角为150°时，第一凸出部202完全由第一凹陷部301内滑出；在第一连接部20和第二连接部60间的夹角处于150°-30°的过程中，第一凸出部202在第一凹陷部301外滑动；当折叠至第一连接部20和第二连接部60之间的夹角为30°时，第一凸出部202逐渐进入到另一第一凹陷部301内，此时第一驱动环30沿轴向移动，并且第一弹簧40逐渐伸长，提供恢复力，进而驱动第一连接部20和第二连接部60继续折叠，直至第一连接部20和第二连接部60完全折叠。相反，在第一连接部20和第二连接部60间的夹角由0°逐渐展开时，第一凸出部202逐渐由第一凹陷部301内滑出，此时驱动第一驱动环30沿轴向移动，以压缩第一弹簧40，提供阻尼力，进而阻止第一连接部20和第二连接部60展开；当展开至第一连接部20和第二连接部60之间的夹角为30°时，第一凸出部202完全由第一凹陷部301内滑出；在第一连接部20和第二连接部60间的夹角处于30°-150°的过程中，第一凸出部202在第一凹陷部301外滑动；当展开至第一连接部20和第二连接部60间的夹角为150°时，第一凸出部202逐渐进入到另一第一凹陷部301内，此时第一驱动环30沿轴向移动，并且第一弹簧40逐渐伸长，提供恢复力，进而驱动第一支撑件2和第二支撑件3继续展开，直至第一支撑件2与第二支撑件3完全展开。
值得说明的是，在第一连接部20随第一支撑件2转动时，第一驱动环30保持相对静止，以使第一连接部20相对于第一驱动环30转动，进而使第一凸出部202逐渐嵌入到第一凹陷部301内，或者第一凸出部202逐渐由第一凹陷部301内滑出。示例性的，可以使第一驱动环30与第二支撑件3连接，以免第一驱动环30随第一连接部20一起转动。
本实施例提供的折叠模组1，第一连接部20上设置有第一轴孔，第一心轴10穿设在第一驱动环30、第一轴孔以及第一弹簧40内，第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，第一弹簧40抵顶第一驱动环30或者第一连接部20，以使第一凸出部202嵌入到第一凹陷部301内；折叠或者展开的过程中，第一凸出部202由第一凹陷部301内滑出，以提供展开或者折叠的阻尼力；与通过转轴上的第一驱动面和第一驱动环30上的第二驱动面配合来带动第一驱动环30转动相比，第一连接部20可以直接带动第一凸出部202和第一凹陷部301相对移动，提高了传动精度。
继续参照图1，本实施例提供的折叠模组1还包括：第二连接部60、第二心轴50、第二驱动环70以及第二弹簧80；第二连接部60上设置有第二轴孔，第二心轴50穿设在第二驱动环70、第二轴孔内以及第二弹簧80内；第二驱动环70和第二连接部60之间设置有第二凸出部602和第二凹陷部701，第二凸出部602位于第二弹簧80和第二凹陷部701之间、或者第二凹陷部701位于第二弹簧80和第二凸出部602之间，第二凸出部602嵌入到第二凹陷部701内；第一心轴10和第二心轴50平行且间隔的设置，第一连接部20上设置有第一齿形结构203，第二连接部60上设置有第二齿形结构603，第一齿形结构203与第二齿形结构603啮合；第二连接部60转动时，第二凸 出部602由第二凹陷部701内滑出。如此设置，可以在转动第一连接部20的同时带动第二连接部60转动，并且第一连接部20和第二连接部60之间的转动的角度相同；与只转动第一连接部20相比，第二连接部60和第一连接部20同时转动，可以缩短转动至折叠状态或者展开状态所需的时间，实现快速折叠和展开。另外，由于第一驱动环30和第一连接部10可以相对于第一心轴10转动，因此安装时只需将第一心轴10穿设在第一驱动环30以及第一轴孔内即可，无需控制第一驱动环30和第一连接部10与第一心轴10的相对位置，安装较为方便；相同的，由于第二驱动环70和第二连接部60可以相对于第二心轴50转动，因此安装时只需将第二心轴50穿设在第二驱动环70以及第二轴孔内即可，无需控制第二驱动环70和第二连接部60与第二心轴50的相对位置，安装较为方便。
具体地，第一连接部20与第一支撑件2连接，第二连接部60与第二支撑件3连接；第二连接部60与第二支撑件3之间的连接方式可以有多中，只要能够保证第一支撑件2和第二支撑件3之间可以顺利转动即可；例如：在第二连接部60上设置第二滑柱601，相应的在第二支撑件3上设置有与第二滑柱601配合的第二滑槽，第一支撑件2和第二支撑件3之间发生相对转动时，第二连接部60绕第二心轴50转动，并且第二滑柱601在第二滑槽内滑动；在实现第二连接部60随第二支撑件3转动的同时，也为第二连接部60相对于第二支撑件3的滑动留出余量，以使转动较为顺畅。
进一步地，在第二连接部60上设置两个第二滑柱601，两个第二滑柱601的中心线共线设置；并且，两个第二滑柱601间隔的设置在第二连接部60的两侧；相应的，在第二支撑件3上设置两个第二滑槽，每一第二滑柱601滑设在一个第二滑槽内，将第二连接部60夹设在两个第二滑槽之间，可以避免第二滑柱601与对应的第二滑槽分离，提高了第二连接部60与第二支撑件3之间的连接稳定性。
本实施例中，第二弹簧80为螺旋弹簧，第二心轴50穿设在第二驱动环70、第二轴孔和第二弹簧80内，第二弹簧80可以将第二驱动环70按压在第二连接部60上。以使第二驱动环70和第二连接部60之间的第二凸出部602嵌入到第二凹陷部701内。
值得说明的是，为了避免在使用过程中第二心轴50与第二驱动环70、第二弹簧80以及第二连接部60脱离，可以在第二心轴50靠近两端的侧壁上设置外螺纹，相应的，在第二心轴50靠近两端的位置均设置与外螺纹配合的抵顶螺母，两个抵顶螺母夹设在第二弹簧80、第二驱动环70以及第二连接部60外侧，以实现第二心轴50与第二弹簧80、第二驱动环70以及第二连接之间的连接。

本实施例中，第二弹簧80用于使第二驱动环70和第二连接部60贴合，以使第二凸出部602嵌入到第二凹陷部701内。具体地，第二弹簧80可以直接与第二连接部60连接，即第二连接部60设置在第二驱动环70和第二弹簧80之间，以在第二弹簧80的抵顶下，使第二连接部60与第二驱动环70贴合。
本实施例中，第二凸出部602的形状与第一凸出部202形状相同，相应的第二凹陷部701的形状与第一凹陷部301的形状相同，并且在第一凸出部202嵌入到第一凹陷部301内时，第二凸出部602也嵌入到第二凹陷部701内，第一凸出部202由第一凹陷部301内滑出时，第二凸出部602也由第二凹陷部701内滑出。如此设置，在折叠或者展开第一支撑件2和第二支撑件3时，第一弹簧40和第二弹簧80同时被压缩或者同时伸长，进而增大阻尼力和恢复力，提高用户体验。
本实施例中，可以使第一驱动环30和第二驱动环70连接，以免在第一连接部20和第二连接部60转动时，第一驱动环30和第二驱动环70随之转动；使得第一连接部20和第二连接部60转动时，第一凸出部202由第一凹陷部301内滑出或者第一凸出部202嵌入到第一凹陷部301内。示例性的，第一驱动环30和第二驱动环70之间可以通过螺栓连接或者卡接的方式连接，只要保证在第一驱动环30和第二驱动环70连接后，第一驱动环30和第二驱动环70不会发生转动即可。
继续参照图1，本实施例优选地，第一驱动环30和第二驱动环70为一体结构。通过铸造或者注塑的方式形成一体结构的第一驱动环30和第二驱动环70，结构简单且加工方便。另外，一体结构的第一驱动环30和第二驱动环70还实现了第一心轴10和第二心轴50之间的连接，此时第一支撑件2和第二支撑件3可以只通过折叠模组1连接即可。

具体地，折叠式电子设备还包括第一支撑件2和第二支撑件3以及折叠屏幕，第一支撑件2和第二支撑件3通过折叠模组1连接，以使第一支撑件2和第二支撑件3可以互相展开或者折叠在一起，折叠屏幕覆盖在第一支撑件2和第二支撑件3上。优选地，第一支撑件2和第二支撑件3可以均呈板状，相应的可以在第一支撑件2和/或第二支撑件3上设置电气元件，以实现折叠式电子设备的功能。
其中，折叠模组1包括：第一连接部20、第一心轴10、第一驱动环30以及第一弹簧40；第一连接部20上设置有第一轴孔，第一心轴10穿设在第一驱动环30、第一轴孔以及第一弹簧40内；第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，第一凸出部202位于第一弹簧40和第一凹陷部301之间、或者第一凹陷部301位于第一弹簧40和第一凸出部202之间，第一凸出部202嵌入到第一凹陷部301内；第一连接部20转动时，第一凸出部202由第一凹陷部301内滑出。
继续参照图7，具体地，折叠设备上具有可互相折叠的第一支撑件2和第二支撑件3，即第一支撑件2和第二支撑件3可以折叠在一起或者展开；第一连接部20与第一支撑件2连接，相应的第二支撑件3可以与第一心轴10连接，当第一支撑件2和第二支撑件3互相折叠或者展开时，第一支撑件2带动第一连接部20转动，以使第一支撑件2相对于第二支撑件3转动。
本实施例优选地，第一连接部20与第一支撑件2之间的连接方式可以有多中，只要能够保证第一支撑件2和第二支撑件3之间可以顺利转动即可；例如：在第一连接部20上设置第一滑柱201，相应的在第一支撑件2上设置有与第一滑柱201配合的第一滑槽，第一支撑件2和第二支撑件3之间相对转动时，第一连接部20绕第一心轴10转动，并且第一滑柱201之在第一滑槽内滑动。如此设置，在实现第一连接部20随第一支撑件2转动的同时，也为第一连接部20相对于第一支撑件2的滑动留出余量，以使转动较为顺畅。
进一步地，在第一连接部20上设置两个第一滑柱201，两个第一滑柱201的中心线共线设置；并且，两个第一滑柱201间隔的设置在第一连接部20的两侧，相应的，在第一支撑件2上设置两个第一滑槽，每一第一滑柱201滑设在一个第一滑槽内，将 第一连接部20夹设在两个第一滑槽之间，可以避免第一滑柱201与对应的第一滑槽分离，提高了第一连接部20与第一支撑件2之间的连接稳定性。
本实施例中第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，示例性的，第一凸出部202可以设置在第一驱动环30朝向第一连接部20的侧壁上，相应的，第一凹陷部301设置在第一连接部20朝向第一驱动环30的侧壁上；或者第一凸出部202设置在第一连接部20朝向第一驱动环30的侧壁上，第一凹陷部301设置在第一驱动环30朝向第一连接部20的侧壁上。
本实施例优选地，合理的设置第一凸出部202和第一凹陷部301的形状和位置，可以在第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202嵌入到第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202滑出至第一凹陷部301外；使第一支撑件2能够保持在展开状态，并且在折叠的过程中提供阻尼力，在第一支撑件2和第二支撑件3展开的过程中提供恢复力，以驱动第一支撑件2和第二支撑件3自动展开。当然合理的设置第一凸出部202和第一凹陷部301的形状和位置，也可以在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202嵌入到第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202滑出至第一凹陷部301外；以使第一支撑件2和第二支撑件3保持在折叠状态，并且在展开的过程中提供阻尼力，在第一支撑件2和第二支撑件3折叠的过程中提供恢复力，以驱动第一支撑件2和第二支撑件3自动折叠。
优选地，可以设置多个第一凹陷部301，多个第一凹陷部301环绕第一心轴10间隔的设置；并且使第一支撑件2相对于第二支撑件3完全展开时，第一凸出部202嵌入到一个第一凹陷部301内，在第一支撑件2相对于第二支撑件3完全折叠时，第一凸出部202嵌入到另一个第一凹陷部301内，以使第一支撑件2和第二支撑件3可以保持在展开状态和折叠状态，并且在刚开始展开和刚开始折叠的过程均提供阻尼力，在即将完全展开和即将完全折叠时提供恢复力，推动第一支撑件2和第二支撑件3完全展开或者完全折叠。
继续参照图1-图6。示例性的，在第一连接部20和第二连接部60的夹角由180°的展开状态，逐渐折叠时，第一凸出部202逐渐由第一凹陷部301内滑出，此时驱动第一驱动环30沿轴向移动，以压缩第一弹簧40，提供阻尼力，进而阻止第一连接部20和第二连接部60折叠；当折叠至第一连接部20和第二连接部60间的夹角为150°时，第一凸出部202完全由第一凹陷部301内滑出；当折叠至第一连接部20和第二连接部60之间的夹角为30°时，第一凸出部202逐渐进入到另一第一凹陷部301内，此时第一驱动环30沿轴向移动，并且第一弹簧40逐渐伸长，提供恢复力，进而驱动第一连接部20和第二连接部60继续折叠，直至第一连接部20和第二连接部60完全折叠。相反，在第一连接部20和第二连接部60间的夹角由0°逐渐展开时，第一凸出部202逐渐由第一凹陷部301内滑出，此时驱动第一驱动环30沿轴向移动，以压缩第一弹簧40，提供阻尼力，进而阻止第一连接部20和第二连接部60展开；当展开至第一连接部20和第二连接部60之间的夹角为30°时，第一凸出部202完全由第一凹陷部301内滑出；当展开至第一连接部20和第二连接部60间的夹角为150°时，第一凸出部202逐渐进入到另一第一凹陷部301内，此时第一驱动环30沿轴向移动，并 且第一弹簧40逐渐伸长，提供恢复力，进而驱动301继续展开，直至301完全展开。
值得说明的是，在第一连接部20随第一支撑件2转动时，第一驱动环30保持相对静止，以使第一连接部20相对于第一驱动环30转动，进而使第一凸出部202逐渐嵌入到第一凹陷部301内，或者第一凸出部202逐渐由第一凹陷部301内滑出。示例性的，可以使第一驱动环30与第二支撑件3连接，以免第一驱动环30随第一连接部20一起转动。
本实施例提供的折叠式电子设备，第一连接部20上设置有第一轴孔，第一心轴10穿设在第一驱动环30、第一轴孔以及第一弹簧40内，第一驱动环30和第一连接部20之间设置有第一凸出部202和第一凹陷部301，第一弹簧40抵顶第一驱动环30或者第一连接部20，以使第一凸出部202嵌入到第一凹陷部301内；折叠或者展开的过程中，第一凸出部202由第一凹陷部301内滑出，以提供展开或者折叠的阻尼力；与通过转轴上的第一驱动面和第一驱动环30上的第二驱动面配合来带动第一驱动环30转动相比，第一连接部20可以直接带动第一凸出部202和第一凹陷部301相对移动，提高了传动精度。
