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。
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。
下面结合附图,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。
参见图1至图6d,本申请实施例提供一种电子设备,包括:第一屏幕支架11、第二屏幕支架12、柔性屏(图中未示出)、第一合页21、第二合页22、第一齿轮31、第二齿轮32和环形齿条33;
柔性屏的一端与第一屏幕支架11固定连接,另一端与第二屏幕支架12固定连接,这样柔性屏可随着第一屏幕支架11和第二屏幕支架12相互张开而展开,以及随着第一屏幕支架11和第二屏幕支架12相互闭合而折叠。
第一合页21的一端与第一齿轮31固定连接,第一合页21的另一端固定在第一屏幕支架11上;第二合页22的一端与第二齿轮32固定连接,第二合页22的另一端固定在第二屏幕支架12上,即第一合页21与第二合页22可以相对转动,同时,齿轮与合页之间是相对静止的,也就是说,齿轮与合页是同步运动的,第一合页21与第二合页22的相对转动能够转换为第一齿轮31和第二齿轮32的相向转动。
可选地,合页可以通过螺钉或者销钉等方式固定在屏幕支架上,本申请实施例对合页固定在屏幕支架上的具体方式不做限定。
在实际使用过程中,用户为实现柔性屏的折叠与展开,可以手动控制第一屏幕支架11和第二屏幕支架12的开合,以此带动第一合页21与第二合页22相对转动。
环形齿条33套设在第一齿轮31和第二齿轮32上,环形齿条33的内侧设置有齿条330,齿条330分别与第一齿轮31和第二齿轮32啮合,这样当第一齿轮31和第二齿轮32随着第一合页21与第二合页22转动时,受齿条330的驱动会沿着该齿条330进行移动。以图2所示场景为例,按照图2中的方向,如果第一齿轮31沿顺时针转动,则在齿条330的驱动下,第一齿轮31会向右平移;同理,如果第二齿轮32沿逆时针转动,则在齿条330的驱 动下,第二齿轮32会向左平移。
在本申请实施例中,通过第一齿轮31和第二齿轮32与环形齿条33啮合,第一屏幕支架11和第二屏幕2支架可相对转动,并带动柔性屏在折叠状态和展开状态之间切换,当柔性屏处于折叠状态时第一齿轮31与第二齿轮32之间的距离大于当柔性屏处于展开状态时第一齿轮31与第二齿轮32之间的距离,即在切换的过程中,第一齿轮31和第二齿轮32受环形齿条33的齿条330驱动,两者会朝相反的方向移动,两者之间的间距会发生变化,齿轮间距的变化会通过合页传动转变为屏幕支架的间距变化。
具体地,图2示出的是柔性屏处于展开状态的场景,图3示出的是柔性屏处于折叠状态的场景;
当柔性屏从展开状态切换至折叠状态,即从图2切换至图3时,齿条330驱动第一齿轮31和第二齿轮32背向移动,即第一齿轮31和第二齿轮32相互远离,齿轮彼此远离通过合页可以转变为屏幕支架的彼此远离,这样即可增大第一屏幕支架11和第二屏幕支架12之间的距离,从而形成用于容纳柔性屏弯折区域的容纳空间,实现增大折弯半径,避免柔性屏被过度挤压出现折痕或折损;
当柔性屏从折叠状态切换至展开状态,即从图3切换至图2时,齿条330驱动第一齿轮31和第二齿轮32相向移动,即第一齿轮31和第二齿轮32相互靠近,齿轮彼此靠近通过合页可以转变为屏幕支架的彼此靠近,这样即可减小第一屏幕支架11和第二屏幕支架12之间的距离,从而使柔性屏展开是两个屏幕支架之间更加紧凑,一方面利于对于柔性屏的支撑,另一方面也可以避免展开过程中对柔性屏造成拉扯损伤。
本申请实施例中,采用环形齿条与齿轮配合,当柔性屏从展开状态切换至折叠状态时,位于两个屏幕支架上第一齿轮和第二齿轮背向移动,进而带动两个屏幕支架彼此远离,在两个屏幕支架之间形成一定的间距,该间距能够容纳柔性屏的弯折区域,实现增大折弯半径,避免柔性屏被过度挤压出现折痕或折损。
需要说明的是,上述第一合页21、第二合页22、第一齿轮31、第二齿轮32、环形齿条33可以统称为一组铰链机构,考虑在折叠与展开过程中的 运动平稳和受力均衡,可设置两组或更多组的铰链机构,图1示出沿设备宽度方向的两端分别设置了两组铰链机构的场景,本申请实施例对电子设备中设置几组铰链机构不做具体限定。
参见图4,在一些实施方式中,环形齿条33的形状为长圆形,环形齿条33包括收尾相接的第一弧形侧壁331、第一直线侧壁332、第二弧形侧壁333和第二直线侧壁334,齿条330设置在第二直线侧壁334的内壁上;
如图3所示,第一直线侧壁332为柔性屏处于折叠状态时相对远离第一屏幕支架11和第二屏幕支架12的侧壁,第二直线侧壁334为柔性屏处于折叠状态时相对靠近第一屏幕支架11和第二屏幕支架12的侧壁。
参见图2和图3,在一些实施方式中,电子设备还包括:阻尼伸缩组件4,阻尼伸缩组件4的两端分别与第一齿轮31和第二齿轮32连接。
在本申请实施例中,由于在设备展开与折叠的过程中第一齿轮31和第二齿轮32会有相对运动,因此设置分别与第一齿轮31和第二齿轮32连接的阻尼伸缩组件4,这样一方面可以在用户操作设备展开与折叠的过程中提供阻尼手感,改善操作体验,另一方面阻尼作用也可以实现设备折叠悬停,方便使用。
参见图5,在一些实施方式中,阻尼伸缩组件4包括:伸缩部40、第一连接部41和第二连接部42;
伸缩部40内部设置阻尼组件,该阻尼组件用于提供阻尼效果;
伸缩部40的两端分别与第一连接部41和第二连接部42固定连接,第一连接部41与第一齿轮31转动连接,第二连接部42与第二齿轮32转动连接;
上述连接方式可以确保当第一齿轮31和第二齿轮32发生相对运动时,通过第一连接部41和第二连接部42带动伸缩部40伸缩,伸缩部40内部的阻尼组件可以在伸缩过程中提供效果。
参见图2和图3,当柔性屏从展开状态切换至折叠状态,即从图2切换至图3时,伸缩部40伸长;当柔性屏从折叠状态切换至展开状态,即从图3切换至图2时,伸缩部40缩短。
具体地,第一连接部41为第一转轴,第二连接部42为第二转轴;
第一齿轮31可转动套设在第一转轴上,第二齿轮32可转动套设在第二 转轴上;
伸缩部40的伸缩方向与第一转轴和第二转轴的轴向垂直。
参见图6a,在一些实施方式中,伸缩部40包括套筒401和套杆402,套筒401套设在套杆402上,即伸缩部40的伸缩是通过套筒401和套杆402的相对运动实现。
阻尼组件包括设置在套筒401内的第一磁性件51和第二磁性件52,以及设置在套杆402上的第三磁性件53,第一磁性件51和第二磁性件52的磁性相同,第一磁性件51和第三磁性件53相异;
在本申请实施例中,阻尼通过磁性件实现,具体为通过异性磁性件之间的吸引力实现阻尼效果,可以理解的是,磁性件可以为磁环或者磁块,本申请实施例对磁性件的具体形式不做限定。
参见图6b,当柔性屏处于展开状态时,第三磁性件53与第一磁性件51的位置相对,即第三磁性件53移动至与第一磁性件51相对的位置,两者相吸;
参见图6c,当柔性屏处于折叠状态时,第三磁性件53与第二磁性件52的位置相对,即第三磁性件53移动至与第二磁性件52相对的位置,两者相吸。
进一步地,如图6a至6c所示,套筒401内设置第一凹部和第二凹部,第一磁性件51设置在第一凹部内,第二磁性件52设置在第二凹部内;
第三磁性件53具有第一凸部;
当柔性屏处于展开状态时,第一凸部与第一凹部配合;当柔性屏处于折叠状态时,第一凸部与第二凹部配合。
在本申请实施例中,通过凹凸配合辅助磁性件进行悬停,使设备在各悬停位置更加稳定。
进一步地,继续参见图6a,阻尼组件还包括设置在套杆402上的第四磁性件54,第四磁性件54和第三磁性件53相同;
继续参见图6b,当柔性屏处于展开状态时,第四磁性件54与第二磁性件52的位置相对,即通过设置第四磁性件54在套杆402上的位置,使第三磁性件53移动至与第一磁性件51相对的位置的同时,第四磁性件54移动至 与第二磁性件52相对的位置,从而实现两对磁性件彼此相吸,提供更强的悬停力,提高设备在展开状态下的结构稳定性,提高使用体验。
进一步地,第四磁性件54具有第二凸部;当柔性屏处于展开状态时,第二凸部与第二凹部配合;这样通过两组磁性件相互吸引以及两组凹凸配合,进一步提高设备在展开状态下的结构稳定性。
进一步地,阻尼组件还包括设置在套筒内401的至少一个第五磁性件,至少一个第五磁性件位于第一磁性件51和第二磁性件52之间;
每个第五磁性件对应不同的柔性屏的折叠角度;
当柔性屏处于任意一个的折叠角度时,第三磁性件53与目标第五磁性件的位置相对,目标第五磁性件为与任意一个的折叠角度对应的第五磁性件。
在本申请实施例中,可以在第一磁性件51和第二磁性件52之间额外设置一个或多个第五磁性件,这样当套杆402上的第三磁性件53移动至与不同的第五磁性件相对的位置时,可以实现设备在不同折叠角度下的悬停。
具体地,结合图6b和图6c,图6b示出了柔性屏处于展开状态,设备展开至180°,第三磁性件53与第一磁性件51的位置相对;图6c示出了柔性屏处于折叠状态,设备折叠至0°,第三磁性件53与第二磁性件52的位置相对,那么在第一磁性件51和第二磁性件52的中间位置设置一个第五磁性件,当第三磁性件53随套杆402移动至与该第五磁性件相对的位置时,即可实现设备折叠至90°的悬停,具体如图6d所示。同理,可以在第一磁性件51和第二磁性件52的中间设置多个第五磁性件,从而实现30°、60°、45°等多种折叠角度的悬停。
需要说明的是,在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外,需要指出的是,本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能,还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能,例如, 可以按不同于所描述的次序来执行所描述的方法,并且还可以添加、省去、或组合各种步骤。另外,参照某些示例所描述的特征可在其他示例中被组合。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端(可以是手机,计算机,服务器,空调器,或者网络设备等)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述,但是本申请并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本申请的启示下,在不脱离本申请宗旨和权利要求所保护的范围情况下,还可做出很多形式,均属于本申请的保护之内。
