为使本发明的目的、 技术方案和优点更加清楚， 下面结合附图对本发明 具体实施例作进一步的详细描述。 附图中，

图 1为根据本发明实施例的 SD卡装置的结构示意图。 图 2为图 1所示 SD卡装置的叠层结构示意图。 如图 1和图 2所示， SD卡装置包括 SD型的上 壳体 1 1和 SD型的下壳体 12、 电路板 1 3、 控制器 41、 TF la sh存储器 42和 无线单元 43。
上壳体 1 1与下壳体 12相扣合， 并且都是 SD卡外型的， 具有标准 SD 卡的接脚， 这样就可以实现利用两个壳体实现了对 SD卡外型的模拟。 图 3 为图 1所示 SD卡装置的上壳体结构示意图。 电路板 13卡合在所述上壳体 11和下壳体 12内。电路板 13上设置有控 制器 41、 TF lash存储器 42和无线单元 43。 电路板 13的作用就是可以将控 制器 41、 TF lash存储器 42和无线单元 43电连接。
控制器 41与所述电路板 13电连接， 控制器 41位于电路板 13的上方， 所有与电源供电以及控制电路相关的元器件均设置在这个区域。
无线单元 43卡设在所述上壳体 11和下壳体 12内， 与所述电路板 13和 控制器 41电连接。 无线单元 43位于电路板 13的右下方， 所有与无线处理、 天线相关的元器件均设置在这个区域。
无线单元 43 中的天线 51可采用 PCB设计， 天线 51所处的位置在无 线单元 43的右下方，这种结构设计保证了天线 51处于电路板 1 3的右下方， 其右侧和下侧均没有电路， 从而给天线 51 在右侧和下侧留出足够的净空 区。 所述天线 51的上方与无线单元 43的其它组成部分相连， 两者之间的 电路布线仅仅包含天线的馈线和用于调节天线匹配的无源器件。 所述天线 51的主体与无线单元 43的其它地方保持例如 1mm以上的距离。 所述天线 的左侧是 TFlash存储器 42。天线主体以及无线单元 43与 TFlash存储器 42 之间没有直接的电路连接， 相互之间没有元器件或者电路走线进入对方区 域。 所述 51天线的左侧和上侧的设计保证了天线 51在左侧和上侧留出了 净空区。 需要说明的是， 无线单元 43中的天线 51也可以采用陶瓷天线等 其它天线。
TF lash存储器 42卡设在所述上壳体 11和下壳体 12 内， 与所述电路板 13和控制器 41电连接。所述 TFlash存储器 42为符合 SDA标准的标准 TF lash 卡。 通过压接方式将所述 TFlash卡固定在电路板 13上， 或将 TFlash卡焊接 在电路板 13上， 使之不能上下左右移动，从而防止 TF lash卡从壳体中掉出。 当然， 也可以采用其它类型的存储器来替代 TF lash存储器 42。
在一个例子中， 控制器 41与无线单元 43相连的接口连线不超过例如 8 个， 接口速率不超过例如 5幌 Hz。 控制器 41与 TFlash存储器 42相连的接口 连线不超过例如 8个， 接口速率不超过例如 5幌 Hz。 各个部分之间除了接口 连线， 不再有任何元器件或 /和电路走线布局在其它模块范围内。
本发明实施例的 SD卡装置，通过将控制器 41设置在电路板 13正上方、 将无线单元 43设置在电路板 13右下方和将 TFlash存储器 42设置在电路 板 13左下方， 可以减少控制器 41、 无线单元 43和 TFlash存储器 42之间 的相互干扰； 将天线 51设置在无线单元 43的右下方，可以为天线 51留出 净空区域； 采用 TFlash卡作为存储卡， 可以保证生产厂家或者使用者自由 更换 SD卡的存储空间。
在无线单元 43与第三方网络节点连接后， 控制器 41根据第三方网络节 点的请求或者本设备自身的请求， 将 TFlash存储器 42 中的数据发送到第三 方网络节点， 或者将第三方网络节点的数据保存到 TFlash存储器 42上。
可以通过压接方式将所述 TFlash卡固定在电路板 13上，或将 TFlash卡 焊接在电路板 13上， 使之不能上下左右移动。
图 1、 图 2和图 3示意了 TFlash卡通过压接方式固定的情形。 如图 2 所示， TFlash卡装配于上壳体 11、 下壳体 12和电路板 13 中间。 如图 1 和图 3所示，在上壳体 11上有定位柱 31、 32、 33、 34和 35,分别位于 TFlash 卡的上侧、 左侧、 下侧、 右侧和右侧。 通过定位柱 31、 32、 33、 34和 35、 上壳体 11、 电路板 13将 TFlash卡固定在电路板 13上。 在电路板 13上与 TFlash卡对应的地方装配有 TFlash卡卡簧 （未图示） ， 用于连接 TFlash 卡和电路板 13之间的电学连接。
本发明实施例公开的 SD卡装置， 通过在上壳体 11 的上侧、 下侧、 左 侧和右侧设置定位柱， 并且 TFlash卡通过五个定位柱卡设在上壳体 11上， 使之不能上下左右移动， 从而防止 TFlash卡从壳体中掉出。
图 4和图 5所示为另一种 TFlash卡固定方式。 图 4为 SD卡装置的电 路板 13、TFlash卡、下壳体 12的另一种固定方式示意图。如图 4所示， TFlash 卡位于电路板 13的左下方， TFlash卡的下侧与 SD卡的下壳体 12边沿平 齐。 图 5为 SD卡装置的上壳体结构示意图。 如图 5所示， 在卡体组装完毕 后， TFlash卡的尾部露出 SD卡的下壳体 12的表面； 在上壳体 11上， 有 位于 TFlash卡 21右侧的定位柱 34和 35以及上侧的定位柱 31,在 TFlash 卡的上侧， 有用于连接 TFlash卡 21和电路板 13的卡簧。 在 TFlash卡的 左侧， 有下壳体 12的壳壁。 TFlash卡卡设在由上壳体 11、 电路板 13、 上 壳体上的定位柱、 下壳体 12上的壳壁以及电路板 13上的卡簧共同组成的 TFlash卡卡槽内。 TFlash卡可以自由地在这个卡槽中插拔。
需要说明的是， 本实施例中的定位柱 31、 34和 35的位置较上一实施 例中的定位柱 31、 34 和 35 的位置更靠近卡壳下方， 从而可以使 TFlash 卡尾部露出卡壳表面， 以便自由拔插。
需要说明的是， 也可以在上壳体 11的上侧、 左侧和右侧设置定位柱。 另外， 定位柱的数量也不仅仅限于 3或 5个。
本发明实施例公开的 SD卡装置， 通过在上壳体 11 的上侧和右侧或者 在上壳体 11的上侧、 左侧和右侧设置定位柱， 并且 TFlash卡位于由上壳 体 11上的定位柱、 上壳体 11、 下壳体 12的壳壁和电路板 13形成的卡槽内， 从而将所述 TFlash卡固定在电路板 13上， 使之不能上下左右移动， 并且所 述 TFlash卡的尾端露出下壳体 12表面， 可以自由拔插。
图 6为 TFlash卡通过焊接方式固定的示意图。 如图所示， 在电路板 13 上采用锡膏或焊锡丝焊接的方式将 TFlash存储器 42焊接在电路板 13上。
