图2是根据本实用新型实施例的移动硬盘的使用结构图；
图3是根据本实用新型实施例的移动硬盘的另一结构图；
图4是根据本实用新型实施例的移动硬盘的PCB示意图。
本实用新型的实施方式
下文中将结合附图对本实用新型的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本实用新型实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定 的顺序或先后次序。
图1是根据本实用新型实施例的移动硬盘的结构图，如图1所示，在本实施例中提供了一种移动硬盘包括：硬盘外壳1、内胆2以及设置于硬盘外壳1和所述内胆2之间的抽拉式柔性塑料片3，抽拉式柔性塑料片3部分包围内胆2并从所述硬盘外壳1的一端拉出。
通过上述结构，在硬盘外壳和内胆之间设置抽拉式柔性塑料片，该抽拉式柔性塑料片部分包围内胆，可沿着内胆从硬盘外壳的一段抽拉出一段作为鼠标垫使用，同时增加了移动硬盘的散热面积，克服了相关技术中移动硬盘功能单一的问题。
可选地，抽拉式柔性塑料片3包括：端部4，内胆2包括：尾部5，端部4和所述尾部5均设置有铜片，抽拉式柔性塑料片3抽出时所述端部4的铜片与所述尾部5的铜片贴合。
通过上述结构，在抽拉式柔性塑料片的端部和内胆的尾部设置铜片，首先当抽拉式柔性塑料片不抽出时也能增加移动硬盘一部分的散热，其次当抽拉式柔性塑料片抽出时两部分铜片贴合能将移动硬盘内部内胆中的热量通过内胆的尾部铜片传递到抽拉式柔性塑料片的端部铜片上，然后热量从抽拉式柔性塑料片的端部铜片传递到抽出的抽拉式柔性塑料片上，更好的实现散热。
可选地，在内胆2内层设置有导热涂层。在内胆内层中设置有导热涂层，这样也是增加移动硬盘内胆中的散热效果，避免移动硬盘发热过高而影响运行。
可选地，在内胆2内表面放置导热硅胶。内胆内放置导热硅胶，紧密贴合硬盘盘体(包裹PCB板的盘体，此处不设置硬盘盘体，将PCB板直接设置在内胆内也是可以的)，导热硅胶可以紧密衔接好内胆和内胆内部PCB，这样硬盘工作时发出的热量由导热硅胶传递到内胆，再由内胆内层的导热涂层传导至移动硬盘中内胆尾部铜片，从而提高移动硬盘散热效果。
可选地，抽拉式柔性塑料片3设置有抽拉卡线装置，所述抽拉卡线装置包括：涡卷弹簧7和固定片8。
抽拉卡线装置可以由涡卷弹簧和固定片组成，涡卷弹簧上缠绕高强度纤 维线连接需要抽拉的柔性塑料片，在绝缘导热柔性塑料片抽出至合理位置时，通过硬盘外壳底部弹出的弹簧固定片顶住抽拉式柔性塑料片的端部，这样塑料片就固定住，并且也不会异常缩回。需要收回时手动让底部弹簧固定片下压，也可以在硬盘外壳相应的安装按钮控制固定片的下压，固定片下压后抽拉式柔性塑料片自动缩回硬盘外壳内。
可选地，所述内胆2为绝缘型导热塑料内胆。绝缘型导热塑料内胆也是为了增加移动硬盘内胆的散热效果，避免移动硬盘发热过高而影响运行。
可选地，抽拉式柔性塑料片3为绝缘导热材质，其中，抽拉式柔性塑料片内嵌柔性铜片。绝缘导热材质和柔性铜片的设置，也是为了增加移动硬盘内胆的散热效果，避免移动硬盘发热过高而影响运行。
可选地，所述硬盘外壳1设置凸起部分9，其中，凸起部分表面为硅胶材质。在移动硬盘盒体表面设置可以作为手掌根部的支撑点(即凸起部分)，这样符合人体工学结构，当抽出抽拉式柔性塑料片时，更加的方便，同时在凸起部分增加硅胶等材料，使用时会更舒适。
可选地，所述移动硬盘还包括：印刷电路板PCB 6，在所述PCB 6上设置有将第一接口转换为第二接口的芯片。可选地，芯片包括：SATA(串口硬盘接口技术，Serial Advanced Technology Attachment)转USB(通用串行总线，Universal Serial Bus)芯片、PS/2转USB的芯片和RS232串口转USB的芯片。第一接口为SATA接口、PS/2接口和RS232串口接口，第二接口都为USB接口。移动硬盘增加PS/2和RS232接口功能，提高了笔记本接口扩展能力，达到了节省外出工作时携带工具数量的目的。
基于上述实施例所提供的技术方案，以下结合一示例对上述技术方案进行说明，图2是根据本实用新型实施例的移动硬盘的使用结构图，如图2所示，移动硬盘，包括：硬盘外壳1、内胆2和设置于所述硬盘外壳1和所述内胆2之间的抽拉式柔性塑料片3，该抽拉式柔性塑料片3部分包围所述内胆2并从所述硬盘外壳1的一端拉出。所述抽拉式柔性塑料片3包括：端部4，所述内胆2包括：尾部5，所述端部4和所述尾部5均设置有铜片，抽拉式柔性塑料片3抽出时端部4的铜片与尾部5的铜片贴合。移动硬盘还包括：印刷电路板PCB(印制电路板，Printed Circuit Board)6，在PCB6上设置有将 第一接口转换为第二接口的芯片。该芯片包括：SATA(串口硬盘接口技术，Serial Advanced Technology Attachment)转USB芯片、PS/2转USB的芯片和RS232串口转USB的芯片。所述内胆2内层设置有导热涂层。该内胆2内表面放置导热硅胶。所述抽拉式柔性塑料片3设置有抽拉卡线装置，所述抽拉卡线装置包括：涡卷弹簧7和固定片8。所述内胆2为绝缘型导热塑料内胆。所述抽拉式柔性塑料片3为绝缘导热材质，其中，该抽拉式柔性塑料片3内嵌柔性铜片。所述硬盘外壳1设置凸起部分9，其中，凸起部分表面为硅胶材质。
硬盘外壳为具有良好散热性能的合金外壳，内胆为绝缘型导热塑料内胆。当绝缘导热柔性塑料片抽出时可以作为鼠标垫使用，并且抽出时端部铜片仍然留在硬盘盒内且与内胆尾部铜片紧密贴合，硬盘工作时发出的热量经铜片传导至拉出的绝缘导热柔性塑料片上。绝缘导热塑料内胆内放置导热硅胶，紧密贴合硬盘盘体(包裹PCB板的盘体，此处不设置硬盘盘体，将PCB板直接设置在内胆内也是可以的)，硬盘工作时发出的热量由绝缘导热塑料内胆内层的导热涂层传导至移动硬盘中内胆尾部铜片，另一块铜片放置在绝缘导热柔性塑料片端部，抽出时端部铜片与移动硬盘中内胆尾部铜片紧密接触，此时热量从内胆尾部铜片传导至绝缘导热柔性塑料片。
抽拉式柔性塑料片可以通过抽拉卡线装置实现抽拉功能，该抽拉卡线装置可以由涡卷弹簧和固定片组成，涡卷弹簧上缠绕高强度纤维线连接需要抽拉的柔性塑料片，在绝缘导热柔性塑料片抽出至合理位置时，通过硬盘外壳底部弹出的弹簧固定片顶住抽拉式柔性塑料片的端部，这样塑料片就固定住，并且也不会异常缩回。需要收回时手动让底部弹簧固定片下压，也可以在硬盘外壳相应的安装按钮控制固定片的下压，固定片下压后抽拉式柔性塑料片自动缩回硬盘外壳内，具备良好的机械性能和手感。在绝缘导热柔性塑料片抽出作为鼠标垫时，抽拉卡线装置上部的移动硬盘盒体表面可以作为手掌根部的支撑点，符合人体工学结构，更可适当增加部分硅胶等材料，使用更舒适。
图3是根据本实用新型实施例的移动硬盘的另一结构图，如图3所示，移动硬盘外壳和绝缘导热塑料内胆之间内嵌抽拉式绝缘导热柔性塑料片，其 中内含高导热性能的柔性铜片(一般导热率高于398W/m.K的铜片定义为高导热铜片)，当该绝缘导热柔性塑料片抽出时可以作为鼠标垫使用，并且抽出时端部铜片仍然留在硬盘盒内且与内胆尾部铜片紧密贴合，硬盘工作时发出的热量经铜片传导至拉出的绝缘导热柔性塑料片上，增加了散热面积，改善了散热性能，在天冷的时候也可用来提高鼠标垫的温度，让使用者感到更加舒适。导热过程如下所述：
绝缘导热塑料内胆内放置导热硅胶，紧密贴合硬盘盘体(包裹PCB板的盘体，此处不设置硬盘盘体，将PCB板直接设置在内胆内也是可以的)。硬盘工作时发出的热量由绝缘导热塑料内胆内层的导热涂层传导至内胆尾部铜片，另一块铜片放置在绝缘导热柔性塑料片端部，抽出时端部铜片与内胆尾部铜片紧密接触，此时热量从内胆尾部铜片传导至绝缘导热柔性塑料片上。
图4是根据本实用新型实施例的移动硬盘的PCB示意图，如图4所示，此实施例中第一接口为SATA接口、PS/2接口和RS232串口接口，第二接口都为USB接口。SATA转USB芯片、PS/2转USB的芯片和RS232串口转USB的芯片这三种芯片都集成在同一块PCB电路板上，放置于绝缘型导热塑料内胆中，对应这三种芯片移动硬盘外侧设有三组接口：PS/2(鼠标键盘)接口2个，RS232 9针串口1个，3个USB接口(分别对应PS/2芯片、RS232芯片和SATA芯片)用来连接笔记本电脑的USB口。连接时需要一根两端都是公头的USB线，这样没有PS/2和RS232串口的笔记本电脑就可以通过移动硬盘盒连接PS/2接口的鼠标键盘和串口设备，考虑到集成了3组芯片，如出现供电不足现象可以由外接电源解决，理论上USB接口供电没问题。这里要注意的是3个USB口的功能是不同的，不能混用。
需要说明的是，SATA转USB芯片是标准的移动硬盘接口芯片，可以使用USB2.0或USB3.0芯片。PS/2转USB的芯片可以使用市面上比较流行的芯片如OKE122-U、CSC0101A-S16G等芯片，基本原理就是把PS/2口的CLK时钟和DATA数据信号转换为USB接口的DN负极和DP正极信号。RS232串口转USB的芯片也可以使用流行的HL340等芯片，其基本原理就是把RS232串口的RX(数据传送端)和TX(数据接收端)信号转换为USB接口的DN负极和DP正极信号。
综上所述，本实用新型实施例达到了以下技术效果：解决了相关技术中移动硬盘功能过于单一的问题，比相关的移动硬盘增加了鼠标垫功能和PS/2和RS232接口，提高了笔记本接口扩展能力和增加了鼠标垫的使用方式，达到了节省外出工作时携带工具数量的目的，同时改善了移动硬盘盒的散热性能。
以上内容仅为本实用新型的可选实施例而已，并不用于限制本实用新型，对于本领域的技术人员来说，本实用新型实施例可以有多种更改和变化。凡在本实用新型实施例的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型实施例的保护范围之内。
工业实用性
根据本实用新型实施例方案，在硬盘外壳和内胆之间设置抽拉式柔性塑料片，抽拉式柔性塑料片部分包围内胆并从硬盘外壳的一端拉出作为鼠标垫使用，从而解决了相关技术中移动硬盘功能过于单一的问题，使得移动硬盘不仅具有其原有的存储功能，还具有将自身结构当作鼠标垫使用，同时还有增加散热效果的功能。
