为使本发明的目的、 技术方案和优点更加清楚明白, 下面结合实施方 式和附图, 对本发明做进一步详细说明。 在此, 本发明的示意性实施方式 及其说明用于解释本发明, 但并不作为对本发明的限定。 本发明用户设备一个实施例中, 该用户设备可以包括电性连接的主体 部件和可动部件, 以及将所述主体部件和可动部件同轴连接的开关控制单 元和旋转驱动单元; 该开关控制单元用于在外力作用下, 消除使所述主体 部件和可动部件相对固定的摩擦力, 以开启所述可动部件的旋转模式; 该 旋转驱动单元用于在所述开关控制单元开启所述可动部件的旋转模式的状 态下, 向可动部件施加预压弹力, 使可动部件相对于主体部件自动旋转, 该预压弹力小于该摩擦力。
具体来说, 本实施例的开关控制单元和旋转驱动单元既可以相对设置 在主体部件的两侧, 也可以设置在主体部件的同侧, 该开关控制单元和旋 转驱动单元的连线方向即为可动部件的转轴方向。 在该开关控制单元未受 到外力作用时, 其可以将可动部件的旋转模式关闭, 也即使该可动部件相 对于主体部件固定; 在受到外力作用时, 该开关控制单元可以开启可动部 件的旋转模式, 也即使可动部件处于可相对于主体部件旋转的状态, 在此 状态下, 该旋转驱动单元可以向可动部件施加预压弹力, 从而使得该可动 部件可以以开关控制单元和旋转驱动单元为转轴面对主体部件自动旋转, 而无需再施加外力使可动部件相对于主体部件旋转。
更具体地来说, 本实施例中的开关控制单元可以通过控制主体部件和 可动部件相对固定的摩擦力, 来控制可动部件的旋转模式是否开启。 当开 关控制单元受到外力作用时, 该开关控制单元可以消除使主体部件和可动 部件相对固定的摩擦力, 从而使得可动部件可以相对于主体部件旋转, 即 开启该可动部件的旋转模式。 由于旋转驱动单元所提供的预压弹力小于使 主体部件和可动部件相对固定的摩擦力, 所以开关控制单元可以在使主体 部件和可动部件相对固定的摩擦力的作用下, 使主体部件和可动部件的旋 转模式关闭。 在使用时, 用户可以通过向开关控制单元施加外力, 以消除 使所述主体部件和可动部件相对固定的摩擦力, 当主体部件和可动部件之 间的摩擦力被消除后, 旋转驱动单元即可将预压弹力施加在可动部件上, 从而使得可动部件在预压弹力作用下, 相对于主体部件旋转。
以用户设备为翻盖手机举例来说, 该主体部件即为翻盖手机设置键盘 部分的手机本体, 而可动部件即可为该手机设置显示屏的翻盖部分, 手机 主体和翻盖部分是电性连接的。 开关控制单元和旋转驱动单元可以将手机 本体和翻盖部分同轴连接。 在手机处于未使用状态时, 翻盖部分和手机主 体在用于使两者相对固定的摩擦力的作用下是闭合的。 在需要将翻盖部分 旋转翻起时, 用户可以向该开关控制单元施加外力, 该开关控制单元在外 力的作用下, 可以消除使主体部件和可动部件相对固定的摩擦力, 从而开 启该翻盖部分的旋转模式, 进一步地, 旋转驱动单元可以在旋转模式开启 的状态下向该翻盖部分施加预压弹力, 因此, 翻盖部分即可在该预压弹力 的作用下, 相对手机主体自动旋转。
在具体实现时, 该预压弹力可以通过弹簧的预紧力来实现, 当然, 也 可以采用其它方式, 例如弹片的弹性形变的方式实现。
可以理解的是, 本实施例中的用户设备也可以是其它可以设置可动部 件的用户设备, 例如带有可旋转 USB接头的 U盘或者数据卡等。
本发明上述实施例, 并不限制开关控制元件和旋转驱动元件的具体结 构, 本领域技术人员可以根据需要设计其具体结构来实现开关控制功能和 旋转驱动功能, 从而在可动部件旋转过程中无需扳动可动部件。
本发明上述实施例的用户设备, 通过设置开关控制单元和旋转驱动单 元, 使得用户在需要转动可动部件时, 可以向该开关控制单元施加外力, 消除使主体部件和可动部件相对固定的摩擦力, 从而开启该可动部件的旋 部件自动旋转, 而无需用户在旋转过程中机械地扳动可动部件, 从而使得 用户设备的操作性较好。 进一步地, 在上述实施例的基础上, 本发明用户设备另一个实施例提 供了开关控制单元和旋转驱动单元设置在用户设备主体部件的两侧, 且与 用户设备连接的可选实现方式。 具体来说, 可动部件的两侧上设有第一安 装孔和第二安装孔, 主体部件在与第一安装孔和第二安装孔对应的位置上 分别设有第一容纳部和第二容纳部, 开关控制单元与第一容纳部和第一安 装孔连接, 旋转驱动单元与第二容纳部和第二安装孔连接。 需要说明的是, 本实施例中的第一安装孔和第二安装孔既可以是设置 在可动部件两侧的独立的孔洞, 也可以是相互连通的通孔。 第一容纳部和 第二容纳部既可是凹槽形状, 也可以是通孔形状。 具体来说, 本实施例的用户设备中, 该开关控制单元可以穿设在主体 部件的第一容纳部和可动部件的第一安装孔上, 而旋转驱动单元可以穿设 在主体部件的第二容纳部和可动部件的第二安装孔上, 因此, 开关控制单 元和旋转驱动单元均是沿可动部件的转轴方向设置。 该开关控制单元可以 控制可动部件旋转模式的开启和关闭, 该旋转驱动单元可以向可动部件施 加自动旋转所需的预压弹力。 在本发明用户设备另一个更加具体的实施例中, 上述开关控制单元可 以包括开关元件和与开关元件连接的制动元件, 开关元件暴露在主体部件 的外侧, 制动元件穿设在第一容纳部和第一安装孔中, 制动元件用于在开 关元件所承受的外力作用下, 消除使主体部件和可动部件相对固定的摩擦 力。 在本实施例中, 该开关元件可以为按钮或者滑动开关等。 用户可以通 过按压该按钮或者滑动该滑动开关向制动元件施加外力, 使制动元件消除 主体部件和可动部件相对固定的摩擦力, 进而使可动部件在旋转驱动单元 的预压弹力作用下面对着主体部件旋转。
下面采用带有可旋转的 USB接头的数据卡作为用户设备, 对本发明的 技术方案进行详细说明。 图 1为本发明用户设备一个实施例的分解结构示意图, 图 2为图 1所示用 户设备的局部结构示意图, 图 3为图 1所示用户设备沿可动部件转轴方向的 剖面结构示意图, 图 4为图 1所示用户设备中开关控制单元的分解结构示意 图, 图 5为图 4所示开关控制单元中凸轮的结构示意图, 图 6为与图 5所示的 凹轮匹配的凸轮的结构示意图, 图 7为图 1所示用户设备中旋转驱动单元的 分解结构示意图, 图 8为图 7所示旋转驱动单元与可动部件连接的剖面结构 示意图, 如图 1〜8所示, 本实施例中, 可动部件 3的两侧设有第一安装孔 31 和第二安装孔 32, 主体部件 4在与第一安装孔 31对应的位置上设有第一容纳 部 41, 在与第二安装孔 32对应的位置上设有第二容纳部 42, 开关控制单元 1 包括: 按钮 11、 两个推杆 12、 第一固定轴 13、 凸轮 14、 凹轮 15、 第一弹簧 16、 第一轴套 17和卡环 18, 第一固定轴 13两端设有第一截止部 131和第二截 止部 132, 凸轮 14上设有两个通孔 141和两个凸起部 142, 凹轮 15上设有与凸 起部 142相配合的凹陷部 151 ; 凸轮 14、 凹轮 15、 第一弹簧 16、 第一轴套 17 以及卡环 18依次穿设在第一截止部 131和第二截止部 132之间, 且卡环 18固 定在第二截止部 132上, 凸起部 142和凹陷部 151相对设置, 第一轴套 17的内 径大于凹轮 15的外径, 两个推杆 12的一端与按钮 11贴合, 两个推杆 12的另 一端分别穿过通孔 141与凹轮 15贴合, 第一轴套 17与第一安装孔 31紧配合, 凸轮 14与第一容纳部 41紧配合, 且按钮 11暴露在主体部件 4外侧; 第一弹簧 16在可动部件 3关闭时处于压缩状态, 以使凸轮 14和凹轮 15在第一弹簧 16的 弹力作用下紧密贴合。 旋转驱动单元 2包括中空的第二固定轴 21、 第二轴套 22和第二弹簧 23 ; 第二固定轴 21穿设在第二安装孔 32中, 且第二固定轴 21 的一端与可动部件 3的内侧贴合, 第二固定轴 21的另一端套设有第二弹簧 23 和第二轴套 22, 第二轴套 22套设在第二弹簧 23上, 第二弹簧 23的一端与第 二轴套 22连接, 第二弹簧 23的另一端与第二安装孔 32内侧连接, 第二轴套 22与第二容纳部 42紧配合; 第二弹簧 23在可动部件 3关闭时处于压缩状态。 可动部件 3和主体部件 4电性连接的线缆即可通过第二固定轴 21的中空部位 与主体部件 4的印刷电路板连接。 在本实施例中, 所述第一弹簧 16可以采用 拉簧, 而第二弹簧 23可以采用扭簧。 在本实施例中, 数据卡的 USB连接头 可以通过线缆与壳体中的印刷电路板(以下简称: PCB )实现电气连接, 而 且,该线缆可以穿过第二轴套 22,将 USB连接头的地与 PCB上的地连接在一 起, 另外, 第一固定轴 13是金属材质的, 该第一固定轴 13也可以将数据卡 的 USB连接头的地与 PCB上的地连接在一起,从而实现数据卡的 USB连接头 通过线缆和第一固定轴 13同时与 PCB左右两边接地, 即双接地。本领域技术 人员可以理解的是, 本实施例亦可采用单接地的形式, 即数据卡的 USB连 接头的地通过线缆或者第一固定轴 13与 PCB的地连接。 需要说明的是, 本实施例仅以两个推杆为例进行说明, 本领域技术人 员可以理解的是, 本实施例也可以根据凸轮 14的结构在凸轮 14上设置更多 通孔 141, 以穿过更多推杆 12, 从而扩大推杆 12与凹轮 15的接触面积, 提高 按钮 11作用的可靠性。 图 9为本发明用户设备中可动部件处于旋转模式关闭状态的结构示意 图, 图 10为图 9所示用户设备中可动部件旋转至 90。 的结构示意图, 图 11为 图 9所示用户设备中可动部件旋转至 180° 的结构示意图, 图 12为图 9所示用 户设备中可动部件旋转至 270° 的结构示意图, 如图 9〜12所示, 并结合上述 图 1〜8所示, 具体来说, 当可动部件 3处于旋转模式关闭的状态, 例如处于 0 度状态时, 旋转驱动单元 2的第二弹簧 23处于最大预压状态, 也即该第二弹 簧 23具有驱动可动部件 3旋转的预压弹力。 本实施例将第二弹簧的预压弹力 表示为 Tl。 而且, 开关控制单元 1的第一弹簧 16也可具有一定的弹力, 从而 使凸轮 14和凹轮 15进行预压, 以使得凸轮 14和凹轮 15之间相对固定。 本实 施例将凸轮 14和凹轮 15之间的相对摩擦力表示为 Τ2, 因此, 在旋转模式关 闭的状态下, Τ2需要大于 Tl, 从而保证凸轮 14和凹轮 15在紧配合状态下相 对摩擦作用可以阻止旋转驱动单元 2的第二弹簧 23使可动部件 3发生旋转。
在按压或者滑动按钮 11后, 两个推杆 12将沿第一固定轴 13的轴心方向 推动凹轮 15, 迫使凹轮 15挤压第一弹簧 16, 而使凹轮 15和凸轮 14分离, 该 分离动作即可相当于开启可动部件的旋转模式。 当凸轮 14和 HJ轮 15之间的 相对摩擦力 Τ2被消除后, 第二弹簧 23即可在预压弹力 T1作用下发生扭转, 也就是使可动部件 3旋转, 直到第二弹簧 23完全松弛或者松开按钮 11, 可动 部件 3停止旋转。 需要说明的是, 本领域技术人员可以根据需要设定第二弹 簧 23完全松弛时可动部件 3的旋转角度, 从而满足不同用户设备的需求。 例 如, 对于本实施例的数据卡来说, 可以设定第二弹簧 23完全松弛时, USB 接头的旋转角度为 180度, 而对于手机来说, 可以设定第二弹簧 23完全松弛 时, 翻盖部件的旋转角度为 160度。 在松开按钮后, 凹轮 15受到第一弹簧 16的挤压, 回到凸轮 14和凹轮 15 紧配合的状态。此时开关控制单元 1的两个推杆 12回到初始状态。由于此时, 凸轮 14和凹轮 15在紧配合状态下存在相对摩擦力 T2, 因此, 该可动部件 3, 即 USB接头将停止旋转并保持在当前的位置。 如果所述第二弹簧 23已经完 全松弛, 所述可动部件 3, 即 USB接头也将保持在最大旋转角度的位置, 例 如 180度。 为了使第一轴套 17与第一安装孔 31、 第一容纳部 41与凸轮 14在可动部 件 3的旋转过程中不发生相对滑动, 本实施例中, 第一轴套 17的横截面的轮 廓可以为多边形, 例如正方形, 从而使得第一轴套 17可以与第一安装孔 31 紧配合而不发生相对滑动, 凸轮 14的横截面的轮廓可以为多边形, 从而使 得凸轮 14与第一容纳部 41紧配合而不发生相对滑动。 第二轴套 22的横截面 的轮廓也可以为多边形, 从而避免第二轴套 22在可动部件 3旋转过程中与第 二容纳部 42发生相对滑动。 可以理解的是, 第一轴套 17与第一安装孔 31之 间、 第一容纳部 41与凸轮 14之间或者第二轴套 22与第二容纳部 42之间也可 以采用粘接等其它卡合方式连接, 或者使第一轴套 17与第一安装孔 31、 第 一容纳部 41与凸轮 14或者第二轴套 22与第二容纳部 42为一体结构, 从而避 免发生相对滑动。
进一步地, 若不采用自动旋转的方式, 本实施例的用户设备亦可采用 手动旋转方式。 例如, 当可动部件 3, 即 USB接头处于 180度状态时, 如果 需要手动旋转该 USB接头到 90度状态, 则可以通过向该 USB接头施加外力, 使得凹轮 15沿第一固定轴 13向第一轴套 17内部运动, 该凹轮 15挤压第一弹 簧 16, 从而使得凹轮 15和凸轮 14分离, 此时, USB接头即可被旋转。 当旋 转到 90度时, 凹轮 15和凸轮 14受到第一弹簧 16的弹力作用再次紧密配合。 由于此时 Τ2〉Τ1, 所以 USB接头可以保持在 90度位置上。 又例如, 当 USB接 头处于 180度状态时, 如果需要手动旋转 USB接头到 270度状态, 则凹轮 15 可以沿第一固定轴 13向第一轴套 17内部运动, 凹轮 15挤压第一弹簧 16, 使 得凹轮 15和凸轮 14分离, USB接头随即旋转。 当旋转 90度后, 凹轮 15和凸 轮 14受到第一弹簧 16的弹力作用再次紧密配合。 由于此时 T2〉T1, 所以 USB 接头可以保持在 270度位置上。 因此, 如果不设置按钮 11, 则用户可以通过 手动旋转 USB接头实现在不同档位上的停顿。 在本实施例中, 由于凸轮 14上设有两个凸起部 142, 凹轮 15上设有四个 凹陷部 151, 因此, 本实施例中 USB接头相对于数据卡主体的旋转档位为 90。 一档。 可以理解的是, 对于凹轮 15上设有六个凹陷部 151的情况来说, USB接头相对于数据卡主体的旋转档位为 60。 一档。 本领域技术人员可以 根据需要设置凸轮 14的凸起部 142与凹轮 15上的凹陷部的结构和个数。 进一步地, 本实施例还可以将凹轮 15上的凹陷部 151设置为具有不同的 凹陷深度。 因此, 用户在按压按钮时, 可以在按压深度较小时, 使可动部 件旋转一定角度, 继续按压增大按压深度时, 可以使可动部件旋转另一角 度。 举例来说, 若凹轮 15的圓周上均匀设有四个凹陷部 151, 其中两个凹陷 深度较大的凹陷部 151相对设置, 两个凹陷深度较小的凹陷部 151相对设置, 因此, 当用户按压按钮的深度较浅时, 该可动部件可以旋转 90。 , 用户继 续按压, 该可动部件可以旋转 180° 。 因此, 通过设计凹陷部的不同凹陷深 度, 用户可以控制可动部件的旋转角度。
本实施例的用户设备, 通过设置按钮控制开关控制单元, 使得用户在 需要转动可动部件时, 可以按动按钮向该开关控制单元施加外力, 使可动 部件和主体部件相对固定的摩擦力消除, 从而开启该可动部件的旋转模式, 然后可动部件即可在旋转驱动单元施加的预压弹力驱动下, 相对于主体部 件自动旋转, 而无需用户在旋转过程中机械地扳动可动部件。 或者用户也 可采用手动方式克服凸轮的凸起部与凹轮的凹陷部之间的摩擦力, 使可动 部件相对于主体部件旋转, 并且对该可动部件旋转的档位进行控制。 因此, 本实施例使得用户设备的操作性较好。 下面采用另一个实施例, 对开关控制单元和旋转驱动单元设置在用户 设备主体部件同侧的技术方案进行详细说明, 本实施例中, 也以该用户设 备为数据卡为例进行说明。 在本实施例中, 可动部件的两侧上设有第一安 装孔和第二安装孔, 主体部件在与第一安装孔和第二安装孔对应的位置上 分别设有第一容纳部和第二容纳部; 开关控制单元和旋转驱动单元位于主 体部件的同侧, 旋转驱动单元与第一容纳部连接, 开关控制单元与第一安 装孔连接, 且开关控制单元与旋转驱动单元连接, 第二安装孔与第二容纳 部用于穿设线缆。 本实施例中的可动部件与上述实施例中图 4所示的可动部 件类似, 此处不再赘述。 图 13为本发明用户设备另一个实施例的局部结构示意图, 图 14为图 13 所示用户设备中开关控制单元和旋转驱动单元的分解结构示意图, 图 15为 图 13所示用户设备中开关控制单元和旋转驱动单元沿第一固定轴方向的剖 面结构示意图, 16为图 13所示用户设备中 HJ轮部分的结构示意图, 如图 13〜16所示, 本实施例中, 开关控制单元 1包括: 开关元件, 例如按钮 11、 第一固定轴 13、 凸轮 14、 凹轮 15、 第一弹簧 16、 第一轴套 17和卡环 18, 第 一固定轴 13两端设有第一截止部 131和第二截止部 132, 凸轮 14上设有至少 两个凸起部, 凹轮 15上设有与凸起部相配合的凹陷部 151, 第一轴套 17的开 口端 171设有阻挡部 172; 旋转驱动单元 2包括: 第二轴套 22、 第二弹簧 23和 滑块 24。 其中, 卡环 18、 第一轴套 17、 第一弹簧 16、 凸轮 14、 凹轮 15、 第 二弹簧 23、 滑块 24以及第二轴套 22依次穿设在第一截止部 131和第二截止部 132之间, 卡环 18和第一轴套 17的封口端 173固定在第二截止部 132的凹槽 133中且封口端 173与卡环 18分离, 凸轮 14固定在第一固定轴 13上, 凸起部 和凹陷部 151相对设置且阻挡部 172将第一弹簧 16、 凸轮 14和凹轮 15围堵在 第一轴套 17内侧, 第一轴套 17的内壁与凹轮 15紧配合, 第一轴套 17的外壁 与图 4所示的可动部件 3上的第一安装孔 31紧配合; 第二弹簧 23的一端与凹 轮 15连接, 第二弹簧 23的另一端与滑块 24连接, 第二轴套 22的外壁与第一 容纳部 41紧配合, 第二轴套 22与滑块 24在该滑块 24的圓周方向上相对静止; 第一截止部 131伸出主体部件 4的外侧, 并与按钮 11贴合; 在可动部件关闭 时, 第一弹簧 16处于压缩状态, 第二弹簧 23处于扭紧状态。 进一步地, 为了将滑块 24与第一固定轴 13固定在一起, 使得该滑块 24 可以保持第一固定轴沿轴向方向上往复运动, 本实施例还可以采用固定销 25插设在滑块 24的第一固定孔 241以及第一固定轴 13的第一截止部 131上的 第二固定孔 134中, 从而使得该滑块 24与第一固定轴 13垂直, 进而使得该滑 块 24可以起到第一固定轴 13往复运动的导向作用。 在使用过程中, 用户可以按压按钮 11, 第一固定轴 13即可在外力作用 下带动凸轮 14向着卡环 18的方向运动, 挤压第一弹簧 16, 使凹轮 15和凸轮 14分离, 该分离动作即可相当于开启可动部件的旋转模式。 当凸轮 14和 HJ 轮 15之间的相对摩擦力被消除后, 第二弹簧 23即可在预压弹力作用下发生 扭转。 第二弹簧 23的一端与滑块 24连接, 其另一端与凹轮 15连接, 而由于 滑块 24和第二轴套 22在该滑块 24的圓周方向上相对静止, 因此, 第二弹簧 23的扭力使凹轮 15带动第一轴套 17转动, 而第一轴套 17与可动部件也是紧 配合的, 因此, 第一轴套 17即可使可动部件旋转, 直到第二弹簧 23完全松 弛或者松开按钮 11, 可动部件停止旋转。 需要说明的是, 本领域技术人员 可以根据需要设定第二弹簧 23完全松弛时可动部件的旋转角度, 从而满足 不同用户设备的需求。 例如, 对于本实施例的数据卡来说, 可以设定第二 弹簧 23完全松弛时, USB接头的旋转角度为 180度, 而对于手机来说, 可以 设定第二弹簧 23完全松弛时, 翻盖部件的旋转角度为 160度。 在松开按钮后, 凸轮 14受到第一弹簧 16的挤压, 回到凸轮 14和凹轮 15 紧配合的状态。 由于此时, 凸轮 14和凹轮 15在紧配合状态下存在相对摩擦 力, 因此, 该可动部件, 即数据卡的 USB接头将停止旋转并保持在当前的 位置。 如果第二弹簧 23已经完全松弛, 可动部件, 即 USB接头也将保持在 最大旋转角度的位置, 例如 180度。 在本实施例中, 可动部件和主体部件电性连接的线缆即可通过第二容 纳部 42以及第二安装孔与主体部件 4的印刷电路板连接。 在本实施例中, 第 一弹簧 16可以采用拉簧, 而第二弹簧 23可以采用扭簧。 在本实施例中, 数 据卡的 USB连接头可以通过线缆与壳体中的 PCB实现电气连接, 而且,该线 缆可以将 USB连接头的地与 PCB上的地连接在一起, 另外, 第一固定轴 13 是金属材质的,该第一固定轴也可以将数据卡的 USB连接头的地与 PCB上的 地连接在一起, 从而实现数据卡的 USB连接头通过线缆和第一固定轴 13同 时与 PCB左右两边接地, 即双接地。 本领域技术人员可以理解的是, 本实施 例亦可采用单接地的形式, 即数据卡的 USB连接头的地通过线缆或者第一 固定轴 13与 PCB的地连接。
本实施例中, 凹陷部 151也可以间隔且均勾地分布在凹轮 15圓周上, 且 可以设置成具有不同的凹陷深度的第一凹陷单元和第二凹陷单元, 其中第 一凹陷单元的凹陷深度大于第二凹陷单元的凹陷深度。 因此, 用户在按压 按钮 11时, 可以在按压深度较小时, 使可动部件旋转一定角度, 继续按压 增大按压深度时, 可以使可动部件旋转另一角度。 举例来说, 若凹轮 15圓 周上均匀设有四个凹陷部 151, 其中两个凹陷深度较大的凹陷部 151相对设 置, 两个凹陷深度较小的凹陷部 151相对设置, 因此, 当用户按压按钮 11的 深度较浅时, 该可动部件可以旋转 90° , 继续按压, 该可动部件即可以旋 转 180° 。 因此, 通过设计凹陷部的不同凹陷深度, 用户可以控制可动部件 的旋转角度。
本实施例的用户设备在使用过程中, 用户在需要转动可动部件时, 可 以按动按钮向该开关控制单元施加外力, 使可动部件和主体部件相对固定 的摩擦力消除, 从而开启该可动部件的旋转模式, 然后可动部件即可在旋 转驱动单元施加的预压弹力驱动下, 相对于主体部件自动旋转, 而无需用 户在旋转过程中机械地扳动可动部件。 或者用户也可采用手动方式克服凸 轮的凸起部与凹轮的凹陷部之间的摩擦力, 使可动部件相对于主体部件旋 转, 并且对该可动部件旋转的档位进行控制。 因此, 本实施例使得用户设 备的操作性较好。 另外, 本实施例的用户设备还可以为用户提供两个档位 或者更多档位的旋转角度, 提高了用户体验。
以上所述的具体实施方式, 对本发明的目的、 技术方案和有益效果进 行了进一步详细说明, 所应理解的是, 以上所述仅为本发明的具体实施方 式而已, 并不用于限定本发明的保护范围, 凡在本发明的精神和原则之内, 所做的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
