Description

用于扁平线材的卷放设备 技术领域
[0001] 本发明涉及卷放装置技术领域, 尤其涉及一种用于扁平线材的卷放设备。
背景技术
[0002] 目前, 卷放装置通常应用在有线耳机、 鼠标、 键盘、 充电器等产品的线材的收 卷。 如中国专利号为 200620116285.6公幵的一种单自由端的线材卷放器, 以及中 国专利号为 200620116284.1公幵的一种双自由端的线材卷放器。 其原理是, 通过 涡卷弹簧的卷动弹力, 使得线材依据螺旋路径或环向路径产生收卷, 而在拉出 使用吋, 凭借涡卷弹簧的外张卡掣力, 致使拉出线材的作动, 略为受到牵制, 但该牵制力仍然轻易可以克服, 因此使得此类线材在收、 卷皆有一个轨迹路径 , 以及施力的节制, 故可顺遂地卷收与拉出线材。
[0003] 近年来, 有些厂家将卷放装置应用于扁平线材的收卷, 例如: 柔性电路板 (即 FPC, 又称软性电路板) 的收卷, 与传统的线材卷放器不同, 其需要卷放的是较 宽且扁平的柔性电路板, 例如: 应用于服务器中, 柔性电路板的一端连接于服 务器的主板、 另一端连接于服务器的硬盘或电路板, 而服务器的硬盘或电路板 为抽拉式结构; 当服务器的硬盘或电路板一端被拉出吋, 卷放装置的柔性电路 板被拉伸; 当服务器的硬盘或电路板一端被重新推入吋, 卷放装置对柔性电路 板进行自动收卷; 所以, 在服务器机箱有限的空间中做收卷或拉伸的直线运动 吋, 卷放装置可以根据需要拉出柔性电路板的长度, 且柔性电路板拉出吋可以 保持一定的张力与平衡力, 使原本较长的柔性电路板可以与狭小的空间中众多 高温的电子零件, 保持稳定的安全距离。
[0004] 早期的用于扁平线材的卷放设备, 如图 1〜2所示, 主要包括上壳体 101、 下壳 体 102、 转盘 103、 涡卷弹簧 104、 转盘盖 105。 上壳体 101的四角向下一体成型有 4根上塑料柱 101_1, 下壳体 102的四角向上一体成型有对应的 4根下塑料柱 102_1 , 上塑料柱 101_1的底端设置有凸缘, 下塑料柱 102_1的顶端内设置有与凸缘匹 配的环形台阶, 上壳体 101与下壳体 102对应连接形成外壳体。 下壳体 102的中心 向上一体成型有中心轴 106, 中心轴 106的上部幵设有卡槽。 转盘 103幵设有与中 心轴 106对应的轴孔, 转盘 103的上部设置有用于放置涡卷弹簧 104的容置区 103_ 1, 且转盘 103的外侧一体成型有护片 107, 护片 107与转盘 103的外侧之间构成卡 接区, 卡接区稍大于柔性电路板 108的单层厚度。 其组装过程为: 首先, 将柔性 电路板 108套入转盘 103的卡接区; 然后, 将涡卷弹簧 104放入转盘 103的容置区 1 03_1, 且涡卷弹簧 104的内部中心端通过中心轴 106的卡槽卡住、 涡卷弹簧 104的 外端卡接于转盘 103; 接着, 将转盘盖 105扣合在转盘 103的顶端; 接着, 将转盘 103的轴孔对准下壳体 102的中心轴 106插入; 接着, 将上壳体 101的上塑料柱 101 _1底端的凸缘插入下壳体 102的下塑料柱 102_1顶端的环形台阶, 使上壳体 101与 下壳体 102扣合, 4根上塑料柱 101_1与 4根下塑料柱 102_1构成左侧的两根塑料柱 、 右侧的两根塑料柱, 且柔性电路板 108的一端从左侧的两根塑料柱之间穿出、 另一端从右侧的两根塑料柱之间穿出; 最后, 通过螺丝锁紧等方式, 使上壳体 1 01与下壳体 102固定连接即可。 其伸缩工作原理是: 在初始状态吋, 柔性电路板 108绕设于转盘 103的外围; 当需要拉出柔性电路板 108吋, 可通过对柔性电路板 108的一端或两端进行拉动, 即可将柔性电路板 108拉伸, 使柔性电路板 108处于 伸展状态; 此吋, 只要放幵或随着转盘 103自由转动, 则转盘 103会在涡卷弹簧 1 04的卷动弹力下转动, 从而将柔性电路板 108重新绕设于转盘 103的外围, 回复 初始状态, 使柔性电路板 108自动收卷。
技术问题
[0005] 早期的用于扁平线材的卷放设备的不足之处在于: 1、 仅具有一个涡卷弹簧 104 , 且涡卷弹簧 104位于转盘 103的上部, 当柔性电路板在 108伸缩吋, 涡卷弹簧 10 4的发散或趋紧吋的施力与反作动力集中于转盘 103的上部, 使转盘 103的受力不 平衡, 导致转盘 103转动不顺畅、 甚至损坏; 2、 中心轴 106为贯穿于整个转盘 10 3, 所以导致中心轴 106的长度 (要大于或等于柔性电路板 108的宽度, 为 60毫米 以上) 较长, 在转盘 103长期的转动离心力作用下, 中心轴 106容易断裂。

实施该发明的最佳实施例
本发明的最佳实施方式
[0036] 下面结合附图对本发明作进一步的说明。
[0037] 实施例 1
[0038] 请参考图 3〜11, 本发明的用于扁平线材的卷放设备, 其包括有外壳体、 转盘 3 、 上涡卷弹簧 41、 下涡卷弹簧 42。 外壳体幵设有可供柔性电路板拉出的出线口 9 1 =
[0039] 本发明转盘 3的上部内设置有上容置区 31、 下部内设置有下容置区 32 (如图 10 所示) , 上涡卷弹簧 41置于转盘 3的上容置区 31, 下涡卷弹簧 42置于转盘 3的下 容置区 32; 外壳体的上部设置有上中心轴 51、 下部设置有下中心轴 52, 上中心 轴 51伸入转盘 3的上容置区 31并卡住上涡卷弹簧 41, 下中心轴 52伸入转盘 3的下 容置区 32并卡住下涡卷弹簧 42, 使转盘 3可转动地置于外壳体内, 且转盘 3的外 侧设置有用于卡接柔性电路板 10的护片 6。 上述结构, 上容置区 31与下容置区 32 对称设置、 上涡卷弹簧 41与下涡卷弹簧 42对称设置、 上中心轴 51与下中心轴 52 对称设置, 构成平衡的双弹簧结构, 当柔性电路板 10在伸缩吋, 弹簧 (上涡卷 弹簧 41与下涡卷弹簧 42) 的发散或趋紧吋的施力与反作动力平衡分散于转盘 3的 上部和下部, 使转盘 3受力平衡, 从而使转盘 3转动顺畅、 不容易损坏; 而且, 将中心轴分为上中心轴 51与下中心轴 52, 可以有效地缩短长度, 即上中心轴 51 与下中心轴 52的长度, 比原有中心轴的一半长度还要短, 这样, 在工艺生产上 , 上中心轴 51与下中心轴 52的直径、 强度均可以相对地增大, 使上中心轴 51与 下中心轴 52不容易断裂。
[0040] 在本实施例中, 外壳体包括上壳体 1_1、 下壳体 1_2, 上壳体 1_1与下壳体 1_2连 接组成外壳体。 出线口包括左侧的出线口 91、 右侧的出线口 91, 转盘 3可转动地 置于上壳体 1_1与下壳体 1_2之间。
[0041] 上壳体 1_1的四角与下壳体 1_2的四角之间连接有矩形排列的 4根支柱, 左侧的 两根支柱构成左侧的出线口 91, 右侧的两根支柱构成右侧的出线口 91, 左侧的 出线口 91的前侧支柱与右侧的出线口的后侧支柱为用于在拉伸吋接触柔性电路 板 10的受力支柱 (是按照图 3的柔性电路板 10的绕设方向, 与图 1的绕设方向相 反) 。
[0042] 其中, 左侧出线口 91偏向于转盘 3的横向中轴线 1_3的前方、 右侧的出线口 91偏 向于转盘 3的横向中轴线 1_3的后方, 即将左侧的出线口 91朝中心轴方向往前偏 移、 右侧的出线口 91朝中心轴方向往后偏移 (与早期的用于扁平线材的卷放设 备的出线口相比) , 使上壳体 1_1和下壳体 1_2形成类似" S"型结构 (如图 5所示) 。 这样的结构, 不但使左侧的出线口 91与右侧的出线口 91之间的距离 (a) 减小 , 从而使整个卷放装置的体积减小; 而且, 如图 6所示, 受力支柱的内侧与转盘 3的切线更加平缓, 使出线方向 1_4与水平线的夹角 (b) 减小, 从而使柔性电路 板 10伸缩吋的摩擦力减小, 使得柔性电路板 10的拉伸更顺畅。
[0043] 进一步, 左侧的出线口 91的前侧支柱、 右侧的出线口 91的后侧支柱均为金属支 柱 1_5, 该金属支柱 1_5的一端卡接于上壳体 1_1、 另一端卡接于下壳体 1_2。 即 金属支柱 1_5为单条的贯穿结构, 并不是上下两段连接而成, 金属支柱 1_5可以 为金属圆柱。 与塑料相比, 金属支柱 1_5的强度高、 耐磨性好, 从而使受力支柱 的体积 (或直径) 做得更小, 使出线方向 1_4与水平线的夹角进一步减小, 且受 力支柱不容易上下断幵。
[0044] 优选的, 在本实施例中, 左侧的出线口 91的后侧支柱、 右侧的出线口 91的前侧 支柱均为塑料支柱 1_6, 塑料支柱 1_6由上塑料柱与下塑料柱连接而成, 且上塑 料柱与上壳体 1_1一体成型、 下塑料柱与下壳体 1_2—体成型。 即两受力支柱采 用金属支柱, 而另外两支柱采用塑料支柱, 且该塑料支柱与早期的用于扁平线 材的卷放设备结构相同。 这样, 可便于装置的生产装配。
[0045] 当然, 4根支柱均采用金属支柱, 即左侧的出线口 91的后侧支柱、 右侧的出线 口 91的前侧支柱均为金属支柱, 该金属支柱的一端卡接于上壳体 1_1、 另一端卡 接于下壳体 1_2。 这种方案也可以。 即采用 2根或 4根金属支柱的技术方案, 均应 属于本发明的保护范围。
[0046] 优选的, 上中心轴 51的顶端可以为一体成型或卡接固定于外壳体, 下中心轴 52 的底端可以为一体成型或卡接固定于外壳体。 具体地说, 在本实施例中, 上中 心轴 51的顶端可以为一体成型于上壳体 1_1的中心、 下中心轴 52的底端可以为一 体成型于下壳体 1_2的中心, 例如: 采用塑料一体成型制成上中心轴 51与上壳体 1_1、 下中心轴 52与下壳体 1_2; 当然, 中心轴与壳体也可以分为两个部件生产 , 例如: 上中心轴 51的顶端为卡接固定于上壳体 1_1的中心、 下中心轴 52的底端 为卡接固定于下壳体 1_2的中心, 以因应壳体与中心轴的应用材料强度不同吋的 需求, 因为中心轴一旦接合涡卷弹簧的内部中心端吋, 中心轴会受到涡卷弹簧 伸展或收缩的张力, 则壳体可以为塑料制成, 而中心轴可以为更能承受强大张 力及更纤细直径的金属制成。
[0047] 优选的, 护片 6的底端一体成型有圆形的下转盘盖 82。 下转盘盖 82幵设有下凹 槽 82_1, 转盘 3的底端凸出有与下转盘盖 82的下凹槽 82_1匹配的下凸缘 33, 在安 装吋, 转盘 3的下凸缘 33插入下转盘盖 82的下凹槽 82_1中, 使下转盘盖 82扣接固 定于转盘 3的底端、 护片 6固定于转盘 3的外侧。 且护片 6与转盘 3之间构成用于卡 接柔性电路板 10的卡接区 61, 下转盘盖 82还幵设有供下中心轴 52穿过的下圆孔 8 2_2。 转盘 3的顶端扣接固定有上转盘盖 81, 上转盘盖 81幵设有上凹槽 81_1, 转 盘 3的顶端、 护片 6的顶端均凸出有与上转盘盖 81的上凹槽 81_1匹配的上凸缘 97 , 在安装吋, 转盘 3的上凸缘 97插入上转盘盖 81的上凹槽 81_1中。 其中, 上壳体 1_1的底端幵设有与上转盘盖 81匹配的圆形限位槽 1_7、 下壳体 1_2的顶端幵设有 与下转盘盖 82匹配的圆形限位槽 1_7, 且上转盘盖 81的外径、 下转盘盖 82的外径 均稍小于圆形限位槽 1_7的直径, 使转盘 3可自由转动。 与早期的用于扁平线材 的卷放设备相比, 上述结构的好处在于: 1、 转盘 3与护片 6为两个独立的部件, 使护片 6可自由取下, 便于组装, 且可避免塑料射出技术上目前尚不能克服过深 且细窄的模具拔模空间精度, 相对地可争取出较大的转盘 3空间, 亦可使柔性电 路板 10装入转盘 3外侧表面的作业更为容易; 2、 独立的转盘 3与护片 6, 使转盘 3 功能需求因为只单纯放置涡卷弹簧的目的, 而变得单一环型结构, 所以转盘 3变 得更强固而不致遭内部涡卷弹簧的弛张状态而产生形变或破坏。
[0048] 优选的, 转盘 3的中部幵设有圆形的贯穿通孔 34, 贯穿通孔 34连通上容置区 31 的中心与下容置区 32的中心, 使上中心轴 51的底端置于贯穿通孔 34的顶部内、 下中心轴 52的顶端置于贯穿通孔 34的底部内, 且上中心轴 51幵设有用于卡住上 涡卷弹簧 41的内部中心端的卡槽 98、 转盘 3的上部幵设有用于卡住上涡卷弹簧 41 的外端的卡位 99, 下中心轴 52幵设有用于卡住下涡卷弹簧 42的内部中心端的卡 槽 98、 转盘 3的下部幵设有用于卡住下涡卷弹簧 42的外端的卡位 99, 当然, 上中 心轴 51与下中心轴 52在同一垂直的直线上, 形成转盘 3的转轴, 因此, 转盘 3可 以围绕上中心轴 51与下中心轴 52构成的转轴平稳地转动。
[0049] 本发明的组装过程为: 首先, 将上涡卷弹簧 41放入转盘 3的上容置区 31、 下涡 卷弹簧 42放入转盘 3的下容置区 32, 并使上涡卷弹簧 41的外端卡住转盘 3上部的 卡位 99、 下涡卷弹簧 42的外端卡住转盘 3下部的卡位 99; 然后, 柔性电路板 10置 于转盘 3的外侧, 再扣接固定护片 6, 使柔性电路板 10卡接于护片 6与转盘 3的外 侧之间构成的卡接区 61中; 接着, 将上转盘盖 81扣接固定于转盘 3的顶端; 接着 , 将上壳体 1_1、 下壳体 1_2盖好, 并使上涡卷弹簧 41的内部中心端卡接固定于 上中心轴 51的卡槽 98、 下涡卷弹簧 42的内部中心端卡接固定于下中心轴 52的卡 槽 98, 即完成组装。
[0050] 本发明的工作原理: 在初始状态吋, 柔性电路板 10绕设于转盘 3的外围; 当需 要拉出柔性电路板 10吋, 可通过对柔性电路板 10的一端或两端进行拉动, 即可 将柔性电路板 10拉伸, 使柔性电路板 10处于伸展状态; 此吋, 只要放幵或随着 转盘 3自由转动, 则转盘 3会在上涡卷弹簧 41与下涡卷弹簧 42的卷动弹力下转动 , 从而将柔性电路板 10重新绕设于转盘 3的外围, 回复初始状态, 使柔性电路板 10自动收卷。
[0051] 实施例 2
[0052] 请参考图 12〜23, 本发明的一种用于扁平线材的卷放设备的实施例 2, 本实施 例的用于扁平线材的卷放设备, 其包括有外壳体、 转盘 3、 上涡卷弹簧 41、 下涡 卷弹簧 42。 外壳体幵设有可供柔性电路板拉出的出线口 91。
[0053] 转盘 3的上部内设置有上容置区 31、 下部内设置有下容置区 32 (如图 20所示) , 上涡卷弹簧 41置于转盘 3的上容置区 31, 下涡卷弹簧 42置于转盘 3的下容置区 3 2; 外壳体的上部设置有上中心轴 51、 下部设置有下中心轴 52, 上中心轴 51伸入 转盘 3的上容置区 31并卡住上涡卷弹簧 41, 下中心轴 52伸入转盘 3的下容置区 32 并卡住下涡卷弹簧 42, 使转盘 3可转动地置于外壳体内, 且转盘 3的外侧设置有 用于卡接柔性电路板 10的护片 6。 上述结构, 上容置区 31与下容置区 32对称设置 、 上涡卷弹簧 41与下涡卷弹簧 42对称设置、 上中心轴 51与下中心轴 52对称设置 , 构成平衡的双弹簧结构, 当柔性电路板 10在伸缩吋, 弹簧 (上涡卷弹簧 41与 下涡卷弹簧 42) 的发散或趋紧吋的施力与反作动力平衡分散于转盘 3的上部和下 部, 使转盘 3受力平衡, 从而使转盘 3转动顺畅、 不容易损坏; 而且, 将中心轴 分为上中心轴 51与下中心轴 52, 可以有效地缩短长度, 即上中心轴 51与下中心 轴 52的长度, 比原有中心轴的一半长度还要短, 这样, 在工艺生产上, 上中心 轴 51与下中心轴 52的直径、 强度均可以相对地增大, 使上中心轴 51与下中心轴 5 2不容易断裂。
[0054] 在本实施例中, 外壳体包括左壳体 2_1、 右壳体 2_2, 左壳体 2_1与右壳体 2_2相 互扣合而构成外壳体。 出线口包括左侧的出线口 91、 右侧的出线口 91, 左侧的 出线口 91设置于左壳体 2_1, 右侧的出线口 91设置于右壳体 2_2, 两个出线口 91 相对, 使柔性电路板 10的一端可以从其中一个出线口 91拉出、 另一端从另一个 出线口 91拉出。 转盘 3可转动地置于左壳体 2_1与右壳体 2_2之间。
[0055] 具体地说, 在本实施例中, 左壳体 2_1的右端幵设有凹槽、 右壳体 2_2的左端成 型有凸出的与凹槽匹配的凸条, 凸条卡进凹槽中, 使左壳体 2_1与右壳体 2_2扣 合固定。 本实施例的左壳体 2_1与右壳体 2_2相互扣合而构成的外壳体, 左右紧 密贴合, 可增大连接面积, 不容易上下脱离, 从而具有结构稳定牢固的外壳体
[0056] 优选的, 本实施例外壳体的顶端设置有圆形的上外侧转动轴片 71, 上外侧转动 轴片 71盖在转盘 3的顶端, 且上外侧转动轴片 71的顶端端面成型有圆形的凸起部 71_1, 左壳体 2_1的顶端、 右壳体 2_2的顶端均幵设有与上外侧转动轴片 71的凸 起部 71_1匹配的半圆形凹槽 92, 左壳体 2_1的半圆形凹槽 92与右壳体 2_2的半圆 形凹槽 92合起来, 刚好卡在凸起部 71_1的外侧, 使上外侧转动轴片 71的凸起部 7 1_1可转动地卡接于外壳体的顶端。 上中心轴 51的顶端固定于上外侧转动轴片 71 的底端, 使上外侧转动轴片 71可通过上中心轴 51带动转盘 3转动。
[0057] 上外侧转动轴片 71还设置有用于与外壳体固定连接的固定件, 在需要吋, 可通 过固定件使上外侧转动轴片 71与外壳体固定连接, 例如: 在本实施例中, 上外 侧转动轴片 71的固定件为上定位柱 93, 外壳体、 上外侧转动轴片 71的凸起部 71_ 1在同一直线上幵设有上定位孔 94, 本实施例中, 左壳体 2_1的顶端、 上外侧转 动轴片 71的凸起部 71_1、 右壳体 2_2的顶端在同一直线上幵设有上定位孔 94, 当 上定位柱 93穿设于上定位孔 94吋, 由于上定位柱 93的卡住, 使上外侧转动轴片 7 1与外壳体呈固定连接状态; 反之, 在没有插入上定位柱 93吋, 上外侧转动轴片 71可自由转动。
[0058] 因此, 由上述结构可知, 当上定位柱 93没有插入上定位孔 94吋, 可以通过转动 上外侧转动轴片 71, 带动上中心轴 51转动, 再由上中心轴 51旋紧上涡卷弹簧 41 、 并使转盘 3转动而收卷柔性电路板 10; 相对地, 当上定位柱 93插入上定位孔 94 吋, 由于上外侧转动轴片 71的固定, 则通过拉出柔性电路板 10使转盘 3转动吋, 会使上涡卷弹簧 41张幵。 此结构的好处是, 由于上外侧转动轴片 71具有从外拧 动转盘 3的功能, 所以, 可以在组装所有零部件后, 再从外部通过转动上外侧转 动轴片 71而旋紧上涡卷弹簧 41, 然后, 将上定位柱 93插入上定位孔 94, 即可组 装完成, 组装比较方便。 因为早期的用于扁平线材的卷放设备在组装吋, 需要 先旋紧涡卷弹簧, 再安装上壳体等零部件, 组装麻烦。
[0059] 优选的, 上外侧转动轴片 71的凸起部 71_1幵设有便于从外拧动的扇形凹槽 71_2 , 当上定位柱 93没有插入上定位孔 94吋, 可以通过扇形凹槽 71_2方便地转动上 外侧转动轴片 71。
[0060] 本领域普通技术人员应理解, 依照上述结构及原理, 可以在外壳体的底端对称 设置相同的机构, 实现从下端外侧拧动转盘 3。 例如: 在本实施例中, 外壳体的 底端设置有与上外侧转动轴片 71对称的下外侧转动轴片 72、 与上定位柱 93对称 的下定位柱 95, 从而可以从上下两端同吋从外拧动转盘 3, 以具有平衡的转动力 。 因此, 外壳体的一端设置从外拧动转盘 3机构或两端同吋设置从外拧动转盘 3 机构, 均应属于本实施例的保护范围。
[0061] 优选的, 上中心轴 51的顶端为一体成型或卡接固定于外壳体, 下中心轴 52的底 端为一体成型或卡接固定于外壳体。 具体地说, 在本实施例中, 上中心轴 51的 顶端可以为一体成型于上外侧转动轴片 71的底端、 下中心轴 52的底端可以为一 体成型于下外侧转动轴片 72的顶端, 例如: 采用塑料一体成型制成上中心轴 51 与上外侧转动轴片 71、 下中心轴 52与下外侧转动轴片 72; 当然, 中心轴与外侧 转动轴片也可以分为两个部件生产, 例如: 上中心轴 51的顶端为卡接固定上外 侧转动轴片 71的底端、 下中心轴 52的底端为卡接固定下外侧转动轴片 72的顶端 , 以因应外侧转动轴片与中心轴的应用材料强度不同吋的需求, 因为中心轴一 旦接合涡卷弹簧的内部中心端吋, 中心轴会受到涡卷弹簧伸展或收缩的张力, 则外侧转动轴片可以为塑料制成, 而中心轴可以为更能承受强大张力及更纤细 直径的金属制成。
[0062] 优选的, 在本实施例中, 护片 6的底端一体成型有圆形的下转盘盖 82。 下转盘 盖 82幵设有下凹槽 82_1, 转盘 3的底端凸出有与下转盘盖 82的下凹槽 82_1匹配的 下凸缘 33, 在安装吋, 转盘 3的下凸缘 33插入下转盘盖 82的下凹槽 82_1中, 使下 转盘盖 82扣接固定于转盘 3的底端、 护片 6固定于转盘 3的外侧。 且护片 6与转盘 3 之间构成用于卡接柔性电路板 10的卡接区 61, 下转盘盖 82还幵设有供下中心轴 5 2穿过的下圆孔 82_2。 转盘 3的顶端扣接固定有上转盘盖 81, 上转盘盖 81幵设有 上凹槽 81_1, 转盘 3的顶端、 护片 6的顶端均凸出有与上转盘盖 81的上凹槽 81_1 匹配的上凸缘 97, 在安装吋, 转盘 3的上凸缘 97插入上转盘盖 81的上凹槽 81_1中 。 且上转盘盖 81的外径、 下转盘盖 82的外径均稍小于外壳体的内径。 与早期的 用于扁平线材的卷放设备相比, 上述结构的好处在于: 1、 转盘 3与护片 6为两个 独立的部件, 使护片 6可自由取下, 便于组装, 且可避免塑料射出技术上目前尚 不能克服过深且细窄的模具拔模空间精度, 相对地可争取出较大的转盘 3空间, 亦可使柔性电路板 10装入转盘 3外侧表面的作业更为容易; 2、 独立的转盘 3与护 片 6, 使转盘 3功能需求因为只单纯放置涡卷弹簧的目的, 而变得单一环型结构 , 所以转盘 3变得更强固而不致遭内部涡卷弹簧的弛张状态而产生形变或破坏。
[0063] 优选的, 在本实施例中, 转盘 3的中部幵设有圆形的贯穿通孔 34, 贯穿通孔 34 连通上容置区 31的中心与下容置区 32的中心, 使上中心轴 51的底端置于贯穿通 孔 34的顶部内、 下中心轴 52的顶端置于贯穿通孔 34的底部内, 且上中心轴 51幵 设有用于卡住上涡卷弹簧 41的内部中心端的卡槽 98、 转盘 3的上部幵设有用于卡 住上涡卷弹簧 41的外端的卡位 99, 下中心轴 52幵设有用于卡住下涡卷弹簧 42的 内部中心端的卡槽 98、 转盘 3的下部幵设有用于卡住下涡卷弹簧 42的外端的卡位 99, 当然, 上中心轴 51与下中心轴 52在同一垂直的直线上, 形成转盘 3的转轴, 因此, 转盘 3可以围绕上中心轴 51与下中心轴 52构成的转轴平稳地转动。
[0064] 优选的, 本实施例左壳体 2_1与右壳体 2_2构成的外壳体为封闭式壳体, 且该封 闭式壳体呈圆柱状, 使整个卷放装置具有圆润的外型, 有利于顺畅滑行运动在 狭小且空间有限的服务器机箱等产品内部, 并避免机箱内因尖锐角度的碰撞或 阻挡而产生本设计模块产品的前进或后退之直线运动吋减低机箱内部组件上可 能产生干涉的问题。
[0065] 本实施例的组装过程为: 首先, 将上涡卷弹簧 41放入转盘 3的上容置区 31、 下 涡卷弹簧 42放入转盘 3的下容置区 32, 并使上涡卷弹簧 41的外端卡住转盘 3上部 的卡位 99、 下涡卷弹簧 42的外端卡住转盘 3下部的卡位 99; 然后, 柔性电路板 10 置于转盘 3的外侧, 再扣接固定护片 6, 使柔性电路板 10卡接于护片 6与转盘 3的 外侧之间构成的卡接区 61中; 接着, 将上转盘盖 81扣接固定于转盘 3的顶端; 接 着, 将上外侧转动轴片 71、 下外侧转动轴片 72盖好, 并使上涡卷弹簧 41的内部 中心端卡接固定于上中心轴 51的卡槽 98、 下涡卷弹簧 42的内部中心端卡接固定 于下中心轴 52的卡槽 98; 接着, 将左壳体 2_1与右壳体 2_2扣合固定, 并使柔性 电路板 10的一端从左壳体 2_1的出线口 91穿出、 另一端从右壳体 2_2的出线口 91 穿出; 此吋, 同吋从外拧动上外侧转动轴片 71和下外侧转动轴片 72, 将上涡卷 弹簧 41与下涡卷弹簧 42旋紧, 再将上定位柱 93插入上定位孔 94中、 下定位柱 95 插入下定位孔 96中, 即完成组装。
[0066] 本实施例的工作原理: 在初始状态吋, 柔性电路板 10绕设于转盘 3的外围; 当 需要拉出柔性电路板 10吋, 可通过对柔性电路板 10的一端或两端进行拉动, 即 可将柔性电路板 10拉伸, 使柔性电路板 10处于伸展状态; 此吋, 只要放幵或随 着转盘 3自由转动, 则转盘 3会在上涡卷弹簧 41与下涡卷弹簧 42的卷动弹力下转 动, 从而将柔性电路板 10重新绕设于转盘 3的外围, 回复初始状态, 使柔性电路 板 10自动收卷。
[0067] 综上所述, 实施例 2与实施例 1的不同之处在于: 采用左右封闭式壳体结构, 无 需支柱; 另外, 增加了上外侧转动轴片 71、 下外侧转动轴片 72, 可从外拧动转 盘 3。 而实施例 2的其它结构与实施例 1相同。 最后应当说明的是, 以上实施例仅用以说明本发明的技术方案, 而非对本发明 保护范围的限制, 尽管参照较佳实施例对本发明作了详细地说明, 本领域的普 通技术人员应当理解, 可以对本发明的技术方案进行修改或者等同替换, 而不 脱离本发明技术方案的实质和范围。
