进一步的，所述条形件对应开口所在边沿的厚度为1-3mm。

请参照图1-3，本发明的实施例一为：
本发明提供的一种拨动式磁生电装置，包括线圈1、磁芯2、绕线圈骨架3和线圈支架4；所述绕线圈骨架3安装在线圈支架4上，所述绕线圈骨架3上设有供磁芯2穿过的通槽31，所述磁芯2设置在通槽31内，所述线圈1绕设在通槽31侧壁外表面上且对应磁芯2设置，所述线圈支架4设有能够容纳所述绕线圈骨架3部分嵌入的开口41。
所述线圈支架4包括条形件42、设置在条形件一端的固定壁43和设置在条形件另一端的环形件44，所述开口41位于条形件42上，所述固定壁43和环形件44位于条形件42的同一侧，所述固定壁43上设有第一安装孔431，所述环形件44上设有第二安装孔441，所述磁芯2的两端分别穿设于第一安装孔431和第二安装孔441中。通过第一安装孔与第二安装孔来固定磁芯，且第一安装孔与第二安装孔位于同一水平面上，使得安装后的磁芯与条形件相互平行，缠绕在磁芯外侧的线圈能够均匀嵌入开口内。其中磁芯靠近第一安装孔的一端面上具有插柱，所述插柱与第一安装孔相适配。
所述条形件42对应开口所在边沿的厚度为1-3mm，优先为1mm，在满足磁回路需求的前提下，有效减小整体厚度。其中，通过图2和图3相对比，可以看出图3中绕线圈骨架部分嵌入，能够增加线圈匝数，使得匝数增加到1100匝。在本实施例中，还可以通过该开口具体尺寸以及形状设计，使得整体厚度得到减小，同时固定壁和环形件的高度也同样减小。改进前，固定壁43和环形件42的高度为8.19mm，而改进后，固定壁43和环形件42的高度为7.19mm。由此可知，减小整体厚度。
所述开口41的横截面形状为矩形，具体尺寸为13.59mm*10.45mm。此结构较为规则，便于加工，同时也方便绕线圈骨架部分嵌入。
所述绕线圈骨架3上还设有两个插件32，两个所述插件32分别位于通槽31的两端，所述插件32的底部设有凸台321，所述凸台321与所述开口41相适配。绕线圈骨架通过两个插件底部的凸台嵌入开口内部，使得绕线圈骨架整体厚度降低，同时两个凸台之间的距离与开口在磁芯长度方向上的大小是相适配的，也就是说，装配后，在磁芯长度方向以及宽度方向上，绕线圈骨架都不会发生移动，起到很好的限位作用。
所述磁发电组件还包括焊接线5，所述绕线圈骨架3靠近环形件一端的插件的相对两侧上分别设有通孔33，所述焊接线5穿设于所述通孔33内。
所述固定壁与条形件相垂直，所述磁芯与条形件相平行。
所述环形件内部填充塑料件，所述第二安装孔位于所述塑料件的中央位置。磁芯与环形件没有直接接触，通过塑料件间接接触。所述线圈支架的材质为金属。环形件的材质为金属，塑料件为绝缘的，起到隔离磁芯与环形件的作用。
需要说明的是：电磁感应现象是指因磁通量变化产生感应电动势的现象，电磁感应定律最基本的公式是e＝-n(dΦ)/(dt)，其中，n为线圈匝数，ΔΦ为磁通量变化量，Δt为发生变化所用时间，e为产生的感应电动势。
虽然触发按键的拨动速度对感应电动势也会产生极小影响，但本方案是在拨动速度匀速且一致的情况下对不同匝数的线圈进行测试的结果如下表1：
匝数（n） 按压发电量（e） 回弹发电量（e1）
800匝 119 uJ 156 uJ
900匝 185 uJ 210 uJ
1000匝 226 uJ 262 uJ
1100匝 266 uJ 380 uJ
1200匝 229 uJ 282 uJ
表1
根据上表1可以看出，当匝数达到1100匝时，按压发电量与回弹发电量均达到性能最佳，但传统的拨动式磁生电装置的体积只能够装配900-1000匝的线圈，而本发明通过在线圈支架上开设开口，并且该开口设计成能够使所述绕线圈骨架部分嵌入，使得在保持原有整体体积的基础上能够装配1100匝的线圈，进而达到提升发电量的效果，以使本发明的拨动式磁生电装置的电气性能更加稳定。
综上所述，本发明提供的一种拨动式磁生电装置，通过在线圈支架上开设开口，并且该开口设计成能够使所述绕线圈骨架部分嵌入，使得在保持现有体积要求下能够增加线圈匝数，进而提升发电量，提升磁发电装置的电气性能的稳定性，同时开口的边沿还能够起到对绕线圈骨架在垂直于嵌入方向上的限位，提高绕线圈骨架与线圈支架装配的稳定性，同时也降低了成本。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
