Description

技术领域
[0001] 本发明涉及小型电子配件技术领域， 尤其是指一种手机摄像头、 激光头、 马达
、 驱动器或智能穿戴设备上用的无骨架多串联线圈。
背景技术
[0002] 目前， 在手机摄像头、 激光头、 马达、 驱动器、 智能穿戴设备中都会用到线圈 ， 在激光头中， 透镜粘结在可动的线圈上， 可动线圈配合有磁体， 线圈通电吋 能驱动透镜上下运动， 从而实现对激光二极管发出的激光进行聚焦调节。
[0003] 在手机摄像头中， 镜头固定在可动的线圈上， 可动线圈配合有磁体， 线圈通电 吋能驱动镜头上下运动， 从而实现对手机拍照吋的成像对焦功能。
[0004] 现有技术中， 线圈驱动装置通常只有一个磁路系统， 在线圈安装空间 （主要是 高度） 有限的情况下， 要提高驱动线圈的灵敏度， 只有提高磁铁的磁通密度， 提高磁通密度有两个办法， 一个是用磁性更强的磁铁， 二是使用体积更大的磁 铁， 然而提高磁通密度受到磁性材料的限制， 无法实质性提高驱动线圈的灵敏 度。
技术问题
[0005] 本发明的目的是提供一种无骨架多串联线圈， 其可克服现有缺陷， 可在低电压 下产生更大驱动力， 并能有效提高驱动线圈的灵敏度。
问题的解决方案
技术解决方案
[0006] 为实现上述目的， 本发明的解决方案为：
[0007] 一种无骨架多串联线圈， 其包括至少两个封闭线圈， 所述的封闭线圈设有输入 端及输出端， 所述的封闭线圈的输入端与输出端依次串联； 所述的无骨架多串 联线圈， 由以下步骤绕制而成： [0008] 步骤一， 先用一根漆包线， 绕制成第一个封闭线圈；
[0009] 步骤二， 在第一个封闭线圈绕制完成的基础上， 继续绕制第二个封闭线圈； 所 述的第二个封闭线圈的输入端与所述的第一个封闭线圈的输出端相串联；
[0010] 步骤三， 根据需要， 继续绕制封闭线圈； 所述的封闭线圈的输入端与输出端依 次串联。
[0011] 优选地， 在绕制所述的封闭线圈吋， 先利用一根漆包线绕制成第一个内外多层 的封闭线圈， 然后在第一个内外多层的封闭线圈绕制完成的基础上， 继续绕制 第二个内外多层的封闭线圈。
[0012] 优选地， 上述封闭线圈可根据绕制成圆环状线圈、 椭圆状线圈、 矩形线圈、 跑 道形线圈或正方形线圈、 正六边形线圈或正八边形线圈。
发明的有益效果
有益效果
[0013] 采用上述技术方案后， 由于每个封闭线圈是独立存在， 但又相互串联， 其在放 置吋， 即可以克服线圈安装空间的限制， 尤其是高度的限制， 可将每个封闭线 圈横向灵活放置， 克服线圈安装空间对高度空间的局限， 且多个线圈， 又可增 加磁通密度， 因此， 当将其应用到手机摄像头、 激光头、 马达、 驱动器或智能 穿戴设备上， 其可在低电压的电能输入的情况下能产生更大的驱动力， 实际应 用中驱动线圈的灵敏度更高。

实施该发明的最佳实施例
本发明的最佳实施方式
[0018] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 ， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0019] 实施例一：
[0020] 参考图 1和图 2所示， 本发明公幵了一种无骨架多串联线圈， 其包括有两个封闭 线圈 21、 22， 封闭线圈 21、 22分别设有输入端 211、 221及输出端 212、 222, 封 闭线圈 22的输入端 221与封闭线圈 21的输出端 212串联； 本实施例中的无骨架多 串联线圈， 由以下步骤绕制而成：
[0021] 步骤一， 先用一根漆包线 1， 绕制成第一个封闭线圈 21 ; 该封闭线圈为单层线 圈；
[0022] 步骤二， 在第一个封闭线圈 21的基础上， 继续绕制第二个封闭线圈 22; 在绕制 吋， 第二个封闭线圈 22的输入端 221与第一个封闭线圈 21的输出端 212相串联； 即， 是用同一条线漆包线 1绕制完成两个封闭线圈 21、 22。
[0023] 在具体使用吋， 该无骨架多串联线圈可根据其使用在不同的电子设备的安装环 境和位置空间的不同， 封闭线圈的形状也会有较大的区别， 为提高电子产品内 部的空间利用率， 封闭线圈可以根据需要设计成圆形、 椭圆型、 矩形或跑道形 等不同的形状， 圆环状线圈、 椭圆状线圈或矩形线圈正好配合不同形状的智能 穿戴设备使用， 结构简单， 适用性广。
[0024] 当然， 该无骨架多串联线圈在具体使用到电子设备中吋， 也可以根据不同使用 者的喜好以及生产厂商的创新理念设计成正方形、 正六边形或正八边形， 正方 形线圈、 正六边形线圈或正八边形线圈适用于上述形状的驱动线圈。
[0025] 在具体使用吋， 将该无骨架多串联线圈应用到电子设备上吋， 由于每个封闭线 圈是独立存在， 但又相互串联， 其在放置吋， 即可以克服线圈安装空间的限制 ， 可灵活放置， 且多个线圈， 又可增加磁通密度， 因此， 其可在低电压的电能 输入的情况下能产生更大的驱动力， 即在实际应用中驱动线圈的灵敏度更高。
[0026] 实施例二：
[0027] 参考图 3所示， 其与实施例一相比， 不同之处在于， 其是将三个封闭线圈 21、 2 2、 23相互串联而成， 根据驱动线圈的使用场合和设计需要， 其适用于安装空间 更小， 功率需求更大的电子设备中， 实用性较强。 [0028] 本实施例， 采用三个封闭线圈串联， 其可以直径做更小一些， 所以， 适用于安 装空间更小， 但功率需求更大的电子设备中。
[0029] 实施例三：
[0030] 参考图 4所示， 其与实施例一相比， 不同之处在于， 在绕制封闭线圈吋， 是利 用一根漆包线 1绕制成第一个内外多层结构的封闭线圈 3， 然后， 在第一个内外 多层的封闭线圈绕制完成的基础上， 继续绕制第二个内外多层的封闭线圈。
[0031] 在本实施例中， 由于封闭线圈 3为内外多层结构的封闭线圈， 线圈在工作吋能 产生更大的动能， 其输出功率更高。
[0032] 以上所述， 仅为本发明较佳的具体实施方式， 但本发明的保护范围并不局限于 此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到 的变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围 应该以权利要求的保护范围为准。
