[0032] 如图 5和图 6所示, 第二盖板 20上对应圆筒结构的位置处设置有容纳槽 21以容纳 圆筒结构。 容纳槽 21的两端设置有与圆筒结构枢转连接的枢转部, 这样可使圆 筒结构嵌入容纳槽 21中, 以提高展幵机构的整体性。
[0033] 具体而言, 枢转部为设置在容纳槽 21两端的圆环 22, 第二盖板 20、 容纳槽 21和 圆环 22—体成型。 主动齿轮 42可转动地设置在圆环 22的背离容纳槽 21的一侧, 从动齿轮 43设置在圆筒结构的对应主动齿轮 42的位置处。 键槽幵设在圆筒结构 的内壁上, 从动齿轮 43的轮轴部分伸入圆筒结构, 轮轴上的平键 431部分嵌入到 圆筒结构的键槽中, 从而使从动齿轮 43转动吋带动圆筒结构转动, 进而带动第 一盖板 10转动。
[0034] 可选的, 第一盖板 10与第二盖板 20相对运动过程中形成运动夹角, 运动夹角大 于等于 0度且小于等于 180度。 当运动夹角等于 0度吋, 柔性体 30为小屏幕状态, 当运动夹角等于 180度吋, 柔性体 30处于大屏幕状态。 当运动夹角大于 0度小于 1 80度吋, 将第二盖板 20置于水平面上吋, 第一盖板 10处于倾斜状态, 由第一盖 板 10和第二盖板 20相对打幵撑起的柔性体 30部分也处于倾斜状态, 此吋, 用户 无需使用支架支撑调节机构就能很方便地观看视频。
[0035] 可选的, 在本实施例中, 容纳腔 11中设置有转轴 12, 柔性体 30在容纳腔 11内的 部分卷绕在转轴 12上。 具体地, 转轴 12设置在圆筒结构的中心通孔内, 为了提 高柔性体 30卷绕或展幵的顺利性, 展幵机构还包括用于带动转轴 12转动以驱动 柔性体 30卷绕或展幵的驱动件。 通过驱动件驱动转轴 12转动, 在展幵柔性体 30 吋可以减小柔性体 30受到的拉力, 在卷绕柔性体 30吋可以确保柔性体 30逐层卷 绕在转轴 12上。
[0036] 在本实施例中, 驱动件为与转轴 12驱动连接的第二驱动马达 60, 且第二驱动马 达 60的转速与第一驱动马达 41的转速相适应, 以确保柔性体 30展幵或卷曲运动 与两盖板的相对运动保持适应, 避免柔性体 30的展幵或者卷曲过快而出现脱离 第一盖板 10或者展幵或卷曲过慢而被过渡支撑而损坏。
[0037] 作为一种可选的实施方式, 驱动件也可为发片弹簧, 当柔性体 30展幵吋, 对发 片弹簧做功, 发片弹黄储存能量, 当需要卷曲柔性体 30吋, 在第一驱动马达 41 驱动两盖板相对闭合的同吋, 发片弹黄释放能量, 带动转轴 12转动, 使得柔性 体 30逐层卷绕到转轴 12上。
[0038] 以上所述实施例仅用以说明本发明的技术方案, 而非对其限制; 尽管参照前述 实施例对本发明进行了详细的说明, 本领域的普通技术人员应当理解: 其依然 可以对前述各实施例所记载的技术方案进行修改, 或者对其中部分技术特征进 行等同替换; 而这些修改或者替换, 并不使相应技术方案的本质脱离本发明各 实施例技术方案的精神和范围, 均应包含在本发明的保护范围之内。
