技术领域
本发明涉及显示装置技术领域，尤其涉及一种显示屏升降旋转方法、支架结构及显示装置
背景技术
显示装置一般包括显示屏、支架结构和底座。为了适应多场景应用，显示屏可以在支架结构上实现旋转功能和升降功能。升降功能可以调整显示屏的位置高度，旋转功能可以调整显示屏为横屏或者竖屏状态。
但是，显示屏的旋转和升降存在操作不便的问题。比如，由于旋转和 升降没有锁定功能，显示屏在任意位置高度均可以完成旋转和升降，因此为了避免旋转和升降相互干扰，通常需要双手操作显示屏的两侧或者通过多个操作步骤，才能完成旋转或者升降。
发明内容
本申请的目的是提供一种显示屏升降旋转方法、支架结构及显示装置，仅需单手或者单指操作，即可一气呵成完成显示屏的旋转或者升降，可以解决或者至少部分解决上述技术问题。
为达此目的，本申请采用以下技术方案：

其中，旋转板上设有供凸柱插入的锁孔；支架主体上设有贯通槽，连接件穿过贯通槽连接连接板，弹性件穿过贯通槽连接连接板；贯通槽包括 用于限制升降旋转锁升降的限位槽，当凸柱逐渐退出锁孔时，升降旋转锁逐渐卡入限位槽。
可选地，升降组件还包括恒力弹簧，恒力弹簧的两端分别连接支架主体和连接板。
可选地，还包括束线组件，束线组件包括：

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，所描述的实施例仅仅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。
实施例一
本实施例提供了一种支架结构，可以供显示屏20在其上旋转和升降，并且其旋转及升降过程更加安全可靠，不会碰撞桌面。
如图1和图2所示，提供了一种显示装置，包括底座10、显示屏20和支架结构。支架结构包括支架主体30、升降组件40和旋转组件50。
本实施例中，为了实现升降，该升降组件40包括固定在支架主体30上的导轨41和与导轨41滑动连接的连接板42。作为一种可选实施方式，导轨41为线性滑轨。
进一步地，为了实现旋转，旋转组件50包括连接连接板42的连接件51和与连接件51转动连接的旋转板52。
因此，显示屏20可以通过与旋转板52固定连接，从而可以通过旋转板52绕连接件51旋转以及通过连接件51在升降组件40上升降。
本实施例中，升降组件40还包括恒力弹簧70，恒力弹簧70的两端分别连接支架主体30和连接板42，从而可以使显示屏20保持在任意高度。
为了防止显示屏20在升降及旋转过程中碰撞桌面，该支架结构还包括解锁键80和升降旋转锁90，解锁键80固定设置在支架主体30的顶部，解锁键80的底面设有第一解锁斜面81，如图2和图3所示。
进一步地，旋转板52上设有锁孔521，升降旋转锁90的一侧设有用于伸入锁孔521的凸柱91，升降旋转锁90的顶面设有与第一解锁斜面81配合的第二解锁斜面92。在升降旋转锁90的另一侧连接有与升降组件40连接的弹性件93。作为一种可选实施方式，弹性件93为弹簧。
本实施例中，当显示屏20处于横屏状态、且位置高度较低(例如低于设定位置或者未达到最高位置)时，升降旋转锁90的凸柱91伸入锁孔521，从而禁止旋转板52绕连接件51转动，达到锁定旋转功能的目的，避免显示屏20旋转而碰撞桌面。当显示屏20通过升降组件40上升时，随着第二解锁斜面92与第一解锁斜面81接触挤压，升降旋转锁90的凸柱91逐渐退出锁孔521，直至完全退出，从而达到解锁旋转功能的目的，此时显示屏20可以从横屏状态切换至竖屏状态。当需要重新锁定旋转功能时，可以将显示屏20转动至锁孔521对准凸柱91，然后下降显示屏20，使得第二解锁斜面92与第一解锁斜面81相互分离，凸柱91在弹性件93的作用下重新插入锁孔521，达到锁定旋转功能的目的。
实施例二
更进一步地，为了解决显示屏20在竖屏状态时下降导致的碰撞桌面的问题，本实施例中，增加了锁定升降功能，可以将旋转功能和升降功能互锁，也即同时只能进行一种功能操作，旋转和升降功能不能同时进行。
具体地，支架主体30上设有贯通槽31，连接件51穿过贯通槽31连接连接板42，弹性件93穿过贯通槽31连接连接板42。
贯通槽31包括用于限制升降旋转锁90升降的限位槽32，当凸柱91逐渐退出锁孔521时，升降旋转锁90逐渐卡入限位槽32。
因此，当显示屏20解锁了旋转功能时，升降旋转锁90卡入限位槽32。如果此时旋转了显示屏20，那么由于凸柱91与锁孔521未对准，升降旋转锁90无法升降，因此此时锁定了升降功能，从而达到在竖屏状态下禁止升降的目的，此为锁定升降功能但解锁旋转功能。
当需要升降时，可以将显示屏20转回横屏状态，使得锁孔521与凸柱91对准，此时显示屏20下降时，凸柱91插入锁孔521，升降旋转锁90退出限位槽32，此为锁定旋转功能但解锁升降功能。
综合实施例一和实施例二的支架结构，可以自动锁定和解锁升降及旋转功能，从而避免显示屏20碰撞桌面，提高使用安全性。
作为实施例一或实施例二的可选实施方式，旋转组件50还包括固定板53、设置在固定板53和旋转板52之间的第一摩擦片54、以及设置在旋转板52和连接件51之间的第二摩擦片55，如图4所示。
旋转板52、第一摩擦片54和第二摩擦片55套设在连接件51上，并通过固定板53调节松紧，使得旋转板52可以绕连接件51转动。
实施例三
一般底座10和显示屏20之间需要线缆连接，为了避免显示屏20的升降过程破坏经过支架结构的线缆，现有技术通常采用外部走线避开运动结构。为此，在实施例一或实施例二的基础上，本实施例提供的支架结构还包括束线组件60，以解决该技术问题，如图5和图6所示。
具体地，该束线组件60包括第一连杆61和第二连杆62。第一连杆61的第一端与连接板42铰接，第一连杆61上开设有用于敷设线缆的第一凹槽611，贯穿第一连杆61的第一端还设有过线孔613。
第二连杆62的第一端与第一连杆61的第二端铰接，第二连杆62的第二端与支架主体30铰接，第二连杆62上开设有用于敷设线缆的第二凹槽621。
作为一种可选实施方式，第一连杆61和第二连杆62之间通过弹性配合轴63铰接。
因此，通过本实施例提供的支架结构，可以内部走线，经过支架结构的线缆可以敷设在第一凹槽611和第二凹槽621内，并可以穿过过线孔613与显示屏20连接。在显示屏20升降过程中，随着第一连杆61绕其第一端转动以及第二连杆62绕其第二端转动，第一连杆61和第二连杆62之间的角度发生变化，但始终保持线缆敷设路径的长度不变，长度等于第一凹槽611和第二凹槽621的长度，从而避免显示屏20的升降过程破坏线缆，达到走线美观的目的，提高了用户体验。
进一步地，第一凹槽611的槽壁上设有第一束线扣612，第二凹槽621的槽壁上设有第二束线扣622，线缆敷设在第一凹槽611和第二凹槽621 处，并被第一束线扣612和第二束线扣622扣住，可以防止线缆脱离凹槽，进而避免破坏线缆。
实施例四
本实施例提供了一种显示屏升降旋转方法，仅需单手或者单指操作，即可一气呵成完成显示屏20的旋转或者升降，操作更加便捷。
为了使显示屏20在支架结构上旋转和升降，支架结构通常包括升降组件40和旋转组件50，如图1至图3所示。
具体地，升降组件40包括固定在支架主体30上的导轨41和与导轨41滑动连接的连接板42。旋转组件50包括连接连接板42的连接件51和与连接件51转动连接的用于安装显示屏20的旋转板52。
如图7所示，该显示屏升降旋转方法包括以下步骤：
S101、当连接板42低于预设位置高度时，锁定旋转板52以禁止其在连接件51上转动，并解锁连接板42以允许其在导轨41上上升和下降；
S102、当连接板42达到预设位置高度时，解锁旋转板52以允许其转动；其中，当旋转板52的转动角度为0度时，锁定连接板42以禁止其上升但允许其下降；当旋转板52的转动角度大于0度时，锁定连接板42以禁止其上升和下降。
应当理解，预设位置高度可以根据显示屏20的尺寸，进行合理设置。本实施例中，该位置也是连接板42能够达到的最高位置。
因此，本实施例提供的一种显示屏升降旋转方法，当连接板42低于预设位置高度时，可以单手或者单指推动显示屏20上升或者下降，而不必受旋转干扰。当连接板42上升到预设位置高度时，由于上升功能被锁定，此时单手或者单指继续施加向上的力，施力部位可以位于显示屏20的两侧底部，显示屏20可以旋转。当显示屏20旋转后，上升和下降功能同时被锁定，此时显示屏20仅有旋转功能，而不必受升降干扰。
进一步地，当连接板42低于预设位置高度时，显示屏20为横屏状态，如图8所示。如此设置，可以尽可能避免显示屏20碰撞桌面。因为连接板42低于预设位置高度时，可以理解为处于较低位置，此时不能旋转可以避免因低位旋转而碰撞桌面。当连接板42达到预设位置高度时，可以理解为 处于较高位置，可以旋转以实现横屏到竖屏的切换，如图9所示，此时旋转板52的转动角度为0度；但在处于竖屏时不能升降可以避免因竖屏升降而碰撞桌面，如图10所示，此时旋转板52的转动角度为90度。
因此，本实施例提供的一种显示屏升降旋转方法，不仅可以单手或者单指推动显示屏20上升或者下降，而且显示屏20不易碰撞桌面而损坏。
需要说明的是，实施例一、二和三均可以应用于实现本实施例提供的显示屏升降旋转方法。但是，本实施例提供的显示屏升降旋转方法，还可以通过其他机械结构实现，也应当落入本申请的保护范围。
实施例五
本实施例提供了一种显示装置，包括如上任一实施例提供的支架结构，同样具备上述任一实施例的有益效果。
除此之外，请参阅图11至图14所示，本实施例提供了一种显示装置，包括显示屏010和升降旋转限位结构，显示屏010通过该升降旋转限位结构，不仅可以实现升降和旋转功能，而且可以避免显示屏010撞击桌面或底盘而受损。
具体地，该升降旋转限位结构包括支架主体020和旋转组件040。旋转组件040包括与支架主体020滑动连接的滑动块041和转动连接滑动块041的旋转安装板042。
其中，旋转安装板042可以用于安装显示屏010。当滑动块041在支架主体020上滑动时，旋转安装板042跟随滑动，从而使得显示屏010实现升降。当旋转安装板042绕滑动块041转动时，显示屏010跟随旋转。
进一步地，为了避免显示屏010因为旋转或者升降而撞击桌面或底盘，支架主体020上开设有升降旋转限位槽021，升降旋转限位槽021包括沿竖向设置的线形槽0211和连接线形槽0211的弧形槽0212。旋转安装板042连接有限位件050，限位件050插入升降旋转限位槽021。
因此，在显示屏010升降以及旋转过程中，限位件050始终处于升降旋转限位槽021内进行限位。具体地，当限位件050位于线形槽0211时，禁止旋转安装板042旋转、但允许滑动块041滑动；当限位件050位于弧形槽0212时，禁止滑动块041滑动、但允许旋转安装板042旋转。
因此，限位件050位于线形槽0211时，显示屏010可以升降、但不可以旋转，使得其在降低到较低位置时，不会因为旋转而撞击到桌面。例如，本实施例中，在升降时，显示屏010处于横屏状态，如果不能限制显示屏010的旋转功能，在显示屏010降低到较低位置时，其容易因旋转而撞击桌面或底盘而受损。
同理，限位件050位于弧形槽0212时，显示屏010可以旋转、但不可以升降，使得其在横屏状态切换至竖屏状态后，不会因为升降而撞击到桌面。例如，本实施例中，在限位件050上升至线形槽0211和弧形槽0212的交界处时，显示屏010可以旋转，旋转过程为横屏状态切换至竖屏状态的过程。当切换为竖屏状态时，如果不能限制显示屏010的升降功能，显示屏010容易因下降而撞击桌面或底盘而受损。
需要说明的是，本实施例提供的升降旋转限位结构，不局限于显示屏010，还可以应用于其他产品。即其他产品也可以通过该升降旋转限位结构实现升降和旋转功能，并且可以避免撞击桌面或底盘而受损。
在本申请的另一实施例中，限位件050为滚轮式结构件，限位件050通过其滚轮式结构与升降旋转限位槽021滚动摩擦连接。通过滚轮式结构，限位件050在升降旋转限位槽021内的运动，从滑动摩擦变为滚动摩擦，可以提高限位件050的运动顺畅度，并增强用户的操作手感。本实施例中，限位件050为轴承件，轴承件包括轴承和轴承固定件。
在本申请的另一实施例中，升降旋转限位结构包括固定在支架主体020上的滑轨组件031和与滑轨组件031滑动连接的连接件032，滑动块041固定连接连接件032。进一步地，支架主体020上开设有贯通槽022，滑动块041和连接件032在贯通槽022处通过紧固件固定连接。例如，滑轨组件031包括两个相对设置的直线导轨，连接件032两端分别滑动连接两个直线导轨。在贯通槽022处连接，可以降低空间占用率和减少整个结构的重量。本实施例中，紧固件为螺丝。
在本申请的另一实施例中，弧形槽0212为圆弧槽。该圆弧槽对应的圆心角可以设置为90°，使得显示屏010可以在横屏和竖屏状态之间切换。
在本申请的另一实施例中，升降旋转限位结构还包括恒力弹簧023， 恒力弹簧023的两端分别连接支架主体020和滑动块041。
请参阅图15至图21，本实施例中提供的一种具有同步旋转升降功能的支撑机构的包括：
支架本体003，支架本体003上连接有支撑板002，支撑板002上安装有升降滑轨005，优选地，升降滑轨005的数量为两条，升降滑轨005上滑动连接有滑动板0015，滑动板0015上转动连接有驱动齿轮0012，驱动齿轮0012上固定连接有用于与显示器001固定连接的连接件0018，具体地，支撑板002上开设有可以供连接件0018穿过的通孔，以便让连接件0018与显示器001进行固定连接；
支架本体003上还固定安装有固定板006，固定板006上固定安装有齿条007，驱动齿轮0012与齿条007啮合；
驱动齿轮0012转动时，驱动齿轮0012沿着齿条007移动以使滑动板0015沿升降滑轨005升降。
本实施例中，与驱动齿轮0012固定连接的连接件0018与显示器001进行固定连接，当用户转动显示器001时，驱动齿轮0012同步发生转动，转动的驱动齿轮0012沿着齿条007移动以使得滑动板0015沿升降滑轨005升降，从而使显示器001的高度同步进行调整。通过上述的设计，用户在调节显示器001旋转时，显示器001会同步升降，极大地简化了用户的调整步骤，用户能够轻松将显示器001从横屏状态切换到纵屏状态，大大增强了用户的体验感。
进一步地，还包括传动齿轮组；
传动齿轮组包括第一双层齿轮0013和第二双层齿轮0014；
第一双层齿轮0013转动连接于滑动板0015上，第一双层齿轮0013具有第一齿轮部001301和第二齿轮部001302，其中，第一齿轮部001301的直径小于第二齿轮部001302的直径，第二齿轮部001302的直径与驱动齿轮0012的直径相等，第一齿轮部001301与驱动齿轮0012啮合；
滑动板0015上固定安装有第一齿轮轴，驱动齿轮0012转动连接于第一齿轮轴上，第二双层齿轮0014转动连接于第一齿轮轴上，第二双层齿轮0014具有第三齿轮部001401和第四齿轮部001402，第三齿轮部001401 的直径与第一齿轮部001301的直径相等，第四齿轮部001402的直径与第二齿轮部001302的直径相等，第二齿轮部001302与第三齿轮部001401啮合，第四齿轮部001402与齿条007啮合。
需要说明的是，当驱动齿轮0012受驱旋转时，驱动齿轮0012带动第一齿轮部001301转动，由于第一齿轮部001301的直径小于驱动齿轮0012，因此，第一齿轮部001301的转速大于驱动齿轮0012，从而使得第一双层齿轮0013的转速大于驱动齿轮0012，第一双层齿轮0013受驱动齿轮0012驱动旋转时，第二齿轮部001302带动第三齿轮部001401旋转，由于第二齿轮部001302的直径大于第三齿轮部001401，因此，第三齿轮部001401的转速大于第二齿轮部001302，从而使得第二双层齿轮0014的转速大于第一双层齿轮0013，第二双层齿轮0014受第一双层齿轮0013驱动旋转时，第四齿轮部001402在齿条007上移动，进而带动滑动板0015沿着升降滑轨005升降。
通过上述的设计，传动齿轮组可使得驱动齿轮0012的转速两次被放大，使显示器001在旋转的过程中同时调整高度，并且确保显示器001在横屏状态下，滑动板0015处于升降滑轨005的最低点，显示器001在竖屏状态下，滑动板0015处于升降滑轨5的最高点。
进一步地，滑动板0015上固定安装有第二齿轮轴，第一双层齿轮0013转动连接于第二齿轮轴上。

支撑板002的顶边边缘排布有多个用于对拉绳0016进行导向的导向轮0017，拉绳0016依次经过多个导向轮0017后与滑动板0015固定连接。
需要说明的是的，通过上述的设计，当滑动板0015沿升降滑轨005下降时，滑动板0015通过拉绳0016对吊板0010进行拉扯，从而使得吊板0010带着第一定力弹簧009的拉伸部往上移动。当滑动板0015沿着升降滑轨005上升时，吊板0010在第一定力弹簧009的弹力作用下往下移动。
上述的第一定力弹簧009的类型、大小可根据显示器001、滑动板0015以及滑动板0015上的零件的总重量进行调整，以使得第一定力弹簧009所提供的拉力与所需支撑的显示器001、滑动板0015以及滑动板0015上的零件的总重量相匹配。例如，当显示器001、滑动板0015以及滑动板0015上的零件为5kg重时，则选取可以提供拉力共为50N的第一定力弹簧009，具体设置可根据实际情况匹配即可，在此不再进行过多赘述。
进一步地，支架本体003的侧边往外凸伸有滑动凸块0020，支撑板002上设置有升降导轨0019，滑动凸块0020滑动连接于升降导轨0019上。
需要说明的是，通过上述的设计，支撑板002可相对于支架本体003滑动升降。
进一步地，支架本体003上安装有第二定力弹簧0011，第二定力弹簧0011安装于滑动凸块0020的上方，且第二定力弹簧0011的拉伸部与升降导轨0019的外壁固定连接。
需要说明的是，第二定力弹簧0011的具体工作原理与第一定力弹簧009的原理相同，第二定力弹簧0011的类型、大小可根据其承载物进行调整。
进一步地，还包括固定底座004；
固定底座004上安装有用于调整支架本体003的俯仰角度的铰接组件0021，铰接组件0021包括至少一个弹簧铰接件，支撑板002通过弹簧铰接件与固定座008转动连接。
需要说明的是，支架本体003通过弹簧铰接件可以相对于固定底座004转动，从而使得用户可以调整显示器001的俯仰角度。
进一步地，固定底座004的底面设置有多个防滑垫片。
需要说明的是，通过上述的设计，可使得固定底座004与桌面之间的摩擦力增大，避免因桌面过于光滑导致固定底座004产生位移的情况。
请继续参阅图15至图21，本实施例提供一种电子设备，其特征在于，包括显示器001以及如实施例一的具有同步旋转升降功能的支撑机构；
显示器001具有背面安装板，背面安装板与支撑机构的连接件0018固定连接。
需要说明的是，本实施中的电子设备的具体调整过程为：
显示器001处于横屏状态，当用户需要将显示器001旋转至竖屏状态下时，用户将显示器001往顺时针方向转动，驱动齿轮0012跟随显示器001顺时针转动，接着，驱动齿轮0012带动第一双层齿轮0013往逆时针方向转动，第一双层齿轮0013带动第二双层齿轮0014往顺时针方向运动，第二双层齿轮0014在转动的同时沿着齿条007往上移动，使得滑动板0015沿着升降滑轨005往上移动，当显示屏切换到竖屏状态时，滑动板0015处于升降滑轨005的顶端。
同理，显示屏处于竖屏状态，当用户需要将显示器001旋转至横屏状态下，用户按照上述过程反向操作即可。

上述的定力弹簧900的类型、大小可根据显示器1400、滑动板700以及滑动板700上的零件的总重量进行调整，以使得定力弹簧900所提供的拉力与所需支撑的显示器1400、滑动板700以及滑动板700上的零件的总重量相匹配。例如，当显示器1400、滑动板700以及滑动板700上的零件为5kg重时，则选取可以提供拉力共为50N的定力弹簧900，具体设置可根据实际情况匹配即可，在此不再进行过多赘述。
