一种实施方式中,在实际装配过程中,也可以先将第一固定板421和第三固定板431装于第一支撑板20,将第二固定板422和第四固定板432装于第二支撑板30,然后将第二支撑板30和第一支撑板20对接,并且第一固定板421与第二固定板422对接,第三固定板431与第四固定板432对接。接着,将第二转轴44依次穿过第一子轴孔321a、第一连接孔421a、第二连接孔、第三连接孔431a、第四连接孔和第二子轴孔,同时使第二转轴44与第一子轴套321、第二固定板422、第四固定板432和第二子轴套322固定连接,与第一固定板421和第三固定板431转动连接。
如图2所示,可折叠支架100处于半展开状态时,第一支撑板20与第二支撑板30平行。第一表面211和第三表面311在同一侧,第二表面212和第四表面312在同一侧。逆时针ω1转动第二支撑板30,带动第二转轴44在第一连接孔421a和第三连接孔431a内逆时针ω1转动,以使第二转轴44相对第一固定板421和第三固定板431逆时针ω1转动。也就是,通过第二支撑板30带动第二转轴44相对第一支撑板20逆时针ω1转动,从而带动第二固定板422相对第一固定板421逆时针ω1转动,第四固定板432相对第三固定板431逆时针ω1转动,进而使第二支撑板30相对第一支撑板20逆时针ω1转动。以使可折叠支架100处于图3所示打开状态。可折叠支架100处于打开状态时,第二支撑板30与第一支撑板20呈夹角设置。此时,第二支撑板30与第一支撑板20的夹角为第二夹角β。第 二夹角β大于0小于180度。本实施例中,第二夹角β为100度。在其他实施例中,第二夹角β也可以是90度,或者120度。
请参阅图3,可折叠支架100处于打开状态时,顺时针ω2转动第二支撑板30,带动第二转轴44在第一连接孔421a和第三连接孔431a内顺时针ω2转动,以使第二转轴44相对第一固定板421和第三固定板431顺时针ω2转动。也就是,通过第二支撑板30带动第二转轴44相对第一支撑板20顺时针ω2转动,从而带动第二固定板422相对第一固定板421顺时针ω2转动,第四固定板432相对第三固定板431顺时针ω2转动,进而带动第二支撑板30相对第一支撑板20顺时针ω2转动。以使可折叠支架100回到图2所示的半展开状态。此时,第一支撑板20与第二支撑板30平行。

本实施例中,可折叠支架100包括定位件,定位件第一转轴41。定位件用于对第二支撑板30的转动角度进行定位,以使第二支撑板30可以悬停在任意角度。本实施例中,定位件为阻尼器。在其他实施例中,定位件也可以是磁性件。
其中,当第二支撑板30绕第二转轴44逆时针ω1转动至打开状态时,也就是,第二支撑板30与第一支撑板20之间的夹角为第二夹角β时,定位件对第二支撑板30进行定位,以阻止第二支撑板30继续相对第一支撑板20逆时针ω1转动,防止第二支撑板30与第一支撑板20之间的夹角大于第二夹角β。并且,通过设置定位件还可以对第二支撑板30起到固定作用,可以使可折叠支架100保持在打开状态。当第二支撑板30相对第一支撑板20顺时针ω2转动至与第一支撑板20平行时,定位件对第二支撑板30进行定位,以阻止第二支撑板30继续绕第二转轴44顺时针ω2转动,使第二支撑板30和第一支撑板20保持平行状态。
一种实施方式中,也可以通过在第二转轴44与第一固定板421之间,以及第二转轴44与第三固定板431之间设置阻尼,从而对第二支撑板30相对第一支撑板20的转动角度进行定位。

本实施例中,通过将卡持部50安装于第一支撑板20的安装槽23内,从而可以节省空间,有利于减薄可折叠支架100的厚度,实现轻薄化。并且,卡持体51可相对安装槽23沿着卡持体51的长度方向移动。在卡持部50位于安装槽23内时,弹性体52处于预压缩状态,且弹性体52具有朝向第一轴套22方向的形变力,从而使弹性体52具有朝向第一轴套22方向滑动的趋势。
请参阅图9,图9是图2所示可折叠支架100中的卡持部50在另一种实施方式中的结构示意图。
本实施方式中,卡持部50还包括第一固定件53和第二固定件54。第一固定件53和第二固定件54均条状结构。第一固定件53和第二固定件54分别位于卡持体51的相对两侧,且第一固定件53和第二固定件54的延伸方向均与卡持体51的延伸方向平行。每一第一弹性体521的第一端521a与第一边513固定连接,第二端521b与第一固定件53固定连接。每一第二弹性体522的第三端522a与第二边514固定连接,第四端522b与第二固定件54固定连接。卡持部50安装于安装槽23,第一固定件53与第一侧壁231固定连接,第二固定件54与第二侧壁232固定连接,且第一固定件53和第二固定件54的延伸方向与Y方向平行。弹性体52处于压缩状态。在其他实施例中,第一固定件53和第二固定件54也可以与安装槽23的底壁固定连接。
请参阅图1和图10,图10是图1所示可折叠支架100处于闭合状态的部分结构示意图。
可折叠支架100处于闭合状态时,第一支撑板20与第二支撑板30沿X方向并排设置,且第一支撑板20和第二支撑板30均与底板10层叠设置。可以理解为第一支撑板20和第二支撑板30为一个整体平板状。卡持体51的第二卡持端512位于第二卡槽441内,并卡持第二转轴44,从而阻止第二转轴44在第一固定板421、和第三固定板431内转动,以阻止第二支撑板30相对第一支撑板20转动。同时,第一卡持端511与第一卡槽411错位,且第一卡持端511抵持第一转轴41表面。弹性体52处于预压缩状态,且弹性体52的弹性回复力具有朝向第一转轴41方向的分力,从而使得卡持体51具有朝向第一转轴41方向滑动的趋势。
逆时针ω1转动第一支撑板20或第二支撑板30,使第一轴套22绕第一转轴41逆时针ω1转动,从而带动第一支撑板20绕第一转轴41逆时针ω1转动。也就是,第一支撑板20和第二支撑板30共同相对底板10逆时针ω1转动。此时,卡持部50跟随第一支撑板20相对第一转轴41转动,直至第一卡持端511转动至与第一卡槽411相对时,弹性体52发 生弹性回复,带动卡持体51朝向第一转轴41方向滑动,使第一卡持端511位于第一卡槽411内,并卡持第一转轴41,以使可折叠支架100处于半展开状态(如图2所示)。
本实施例中,通过设置卡持部50,且可折叠支架100处于闭合状态时,卡持体51卡持第二转轴44,转动第一支撑板20或第二支撑板30时,第一支撑板20和第二支撑板30能够保持相对不动,也就是第一支撑板20和第二支撑板30能够共同相对底板10转动,从而可以实现可折叠支架100从闭合状态转化为半展开状态。
请参阅图2和图11,图11是图2所示可折叠支架100处于半展开状态时的部分结构示意图。
可折叠支架100处于半展开状态时,第一支撑板20与第二支撑板30平行,第一支撑板20与底板10的夹角为第一夹角α。卡持体51的第一卡持端511位于第一卡槽411内,并卡持第一转轴41,同时,锁持件锁持第一转轴41,卡持体51和锁持件共同锁持第一转轴41,从而可以阻止第一支撑板20继续绕第一转轴41转动。第二卡持端512脱离第二卡槽441,并释放第二转轴44。转动第二支撑板30,可使第二支撑板30相对第一支撑板20转动。
逆时针ω1转动第二支撑板30,带动第二转轴44相对第一支撑板20逆时针ω1转动,从而带动第二固定板422相对第一固定板421逆时针ω1转动,第四固定板432相对第三固定板431逆时针ω1转动,进而使第二支撑板30相对第一支撑板20逆时针ω1转动,以使可折叠支架100处于打开状态(如图3所示)。此时,第二支撑板30与第一支撑板20的夹角为第二夹角β,第一支撑板20与底板10的夹角为第一夹角α。定位件对第二支撑板30进行定位,使第一支撑板20和第二支撑板30的夹角保持在第二夹角β,可折叠支架100保持在打开状态。并且,卡持体51的状态与可折叠支架100处于半展开状态时的状态一致,卡持体51的第一卡持端511位于第一卡槽411内,并卡持第一转轴41,以阻止第一支撑板20相对底板10转动。
请继续参阅图3,顺时针ω2转动第二支撑板30,带动第二转轴44相对第一支撑板20顺时针ω2转动,从而带动第二固定板422相对第一固定板421顺时针ω2转动,第四固定板432相对第三固定板431顺时针ω2转动,进而使第二支撑板30相对第一支撑板20顺时针ω2转动,直至第一支撑板20与第二支撑板30平行,以使可折叠支架100处于图2所示半展开状态。需要说明的是,可折叠支架100处于打开状态时,顺时针ω2转动第二支撑板30需要的力小于卡持体51和锁止件对第一转轴41的锁持力,从而可以保证在顺时针ω2旋转第二支撑板30时,第二支撑板30相对第一支撑板20转动,而第一支撑板20与底板10相对静止,从而保证可折叠支架100的开合逻辑。
请参阅图2和图11,可折叠支架100处于半展开状态时,第一支撑板20与第二支撑板30平行,第一支撑板20与底板10的夹角为第一夹角α。卡持体51的第一卡持端511位于第一卡槽411内,并卡持第一转轴41。同时,第一合页42和第二合页43对第二支撑板30进行定位,以阻止第二支撑板30继续相对第一支撑板20顺时针ω2转动,使第一支撑板20和第二支撑板30保持在平行状态。
顺时针ω2转动第一支撑板20或第二支撑板30,使第一轴套22绕第一转轴41顺时针ω2转动,从而带动第一支撑板20绕第一转轴41顺时针ω2转动。也就是,第一支撑板20 和第二支撑板30共同相对底板10顺时针ω2转动。此时,卡持部50跟随第一支撑板20相对第一转轴41转动,第一卡持端511脱离第一卡槽411,并且在第一转轴41的抵持作用下,卡持体51朝向第二转轴44方向移动,直至第二卡持端512位于第二卡槽441内,并卡持第二转轴44,以使可折叠支架100处于图1所示闭合状态。
本实施例中,第一卡槽411其中一个侧壁为弧面。当可折叠支架100从半展开状态变换为闭合状态时,顺时针ω2转动第一支撑板20时,卡持部50跟随第一支撑板20相对第一转轴41转动,第一卡持端511从第一卡槽411的弧形侧壁滑出,并脱离第一卡槽411。
请参阅图3,可折叠支架100处于打开状态时,第二支撑板30可用于放置平板电脑或手机,以方便用户的使用。底板10的上表面11可用于放置键盘,键盘与平板电脑连接,以实现平板电脑与键盘之间的信号传输。
一种实施方式中,可折叠支架100还包括键盘。键盘位于底板10的上表面11,并与底板10固定连接。键盘与平板电脑连接,以实现平板电脑与键盘之间的信号传输。
请参阅图12和图13,图12是本申请另一实施例提供的可折叠支架100的部分结构示意图;图13是图12所示可折叠支架的部分分解结构示意图。
本申请另一实施例中,与上一实施例的不同之处在于,第一转动部包括凸块412,凸块412与第一转轴41固定连接,并凸出于第一转轴41的表面,且凸块412位于第一转轴41的中部,与卡持部50相对设置。可以理解为凸块位于第一卡槽411内。
可折叠支架100处于闭合状态时,凸块412抵持第一卡持端511,卡持体51的第二卡持端512位于第二卡槽441内,并卡持第二转轴44,从而阻止第二转轴44转动,以阻止第二支撑板30相对第一支撑板20转动。转动第一支撑板20,可使第一轴套22绕第一转轴41转动,从而带动第一支撑板20相对第一转轴41转动。
逆时针ω1转动第一支撑板20或第二支撑板30,使第一支撑板20和第二支撑板30共同相对底板10逆时针ω1转动。此时,卡持部50跟随第一支撑板20相对第一转轴41转动,直至第一卡持端511转动至与凸块412脱离时,弹性体52发生弹性回复,带动卡持体51朝向第一转轴41方向滑动,使第二卡持端512脱离凸块412,以使可折叠支架100处于半展开状态(如图2所示)。
可折叠支架100处于半展开状态时,锁持件锁持第一转轴41,从而可以阻止第一支撑板20继续转动。同时,第二卡持端512脱离第二卡槽441,并释放第二转轴44。转动第二支撑板30,可使第二支撑板30相对第一支撑板20转动。
逆时针ω1转动第二支撑板30,带动第二转轴44相对第一支撑板20逆时针ω1转动,从而带动第二固定板422相对第一固定板421逆时针ω1转动,第四固定板432相对第三固定板431逆时针ω1转动,进而使第二支撑板30相对第一支撑板20逆时针ω1转动,以使可折叠支架100处于打开状态(如图3所示)。可折叠支架100处于打开状态时,卡持体51的状态与可折叠支架100处于半展开状态时的状态一致,卡持体51的第一卡持端511脱离凸块412,第二卡持端512脱离第二卡槽441,并释放第二转轴44。
顺时针ω2转动第二支撑板30,带动第二转轴44相对第一支撑板20顺时针ω2转动,从而带动第二固定板422相对第一固定板421顺时针ω2转动,第四固定板432相对第三固定板431顺时针ω2转动,进而使第二支撑板30相对第一支撑板20顺时针ω2转动,直至 第一支撑板20与第二支撑板30共面,以使可折叠支架100处于图2所示半展开状态。
可折叠支架100处于半展开状态时,顺时针ω2转动第一支撑板20或第二支撑板30,使第一轴套22绕第一转轴41顺时针ω2转动,从而带动第一支撑板20绕第一转轴41顺时针ω2转动。也就是,第一支撑板20和第二支撑板30共同相对底板10顺时针ω2转动。此时,卡持部50跟随第一支撑板20相对第一转轴41转动,凸块412抵持第一卡持端511,使卡持体51朝向第二转轴44方向移动,直至第二卡持端512位于第二卡槽441内,并卡持第二转轴44,以使可折叠支架100回到图1所示闭合状态。
本实施例中,凸块412的侧面为弧面,当可折叠支架100从半展开状态变换为闭合状态时,顺时针ω2转动第一支撑板20时,卡持部50跟随第一支撑板20相对第一转轴41转动,第一卡持端511顺着凸块412的侧面滑动至与凸块相对,使凸块412抵持第一卡持端。
请参阅图14,图14是本申请提供的电子设备200的结构示意图。
电子设备200包括移动终端110和上述可折叠支架100。移动终端110可以是平板电脑或者手机。移动终端110安装于可折叠支架100,具体安装于第二支撑板30的第三表面311,并与第二支撑板30连接。本实施例中,移动终端110与第二支撑板30也可以是磁吸连接。在其他实施例中,移动终端110也可以粘接于第二支撑板30,或者移动终端110与第二支撑板30卡持连接,或者移动终端110与第二支撑板30螺接,或者也可以是其他的连接方式,只要能实现移动终端110与第二支撑板30的连接即可。
其中,移动终端110还与键盘连接,以实现移动终端110与键盘之间的信号传输。本实施例中,移动终端110与键盘通过无线方式实现连接,如蓝牙连接或无线局域网连接。在其他实施方式中,移动终端110与键盘也可以有线连接。
以上,仅为本申请的部分实施例和实施方式,本申请的保护范围不局限于此,任何熟知本领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以权利要求的保护范围为准。
