现有移动宽带产品天线布局一般形式如图 1所示， 一般将天线 2单独设置在移动宽 带产品机壳内的一端， 与移动宽带产品机壳内的电路板组件并列设置， 这样天线 2不会 被电路板组件 1 (PCBA, Printed Cirruit Board Assembly) 遮挡， 可保证天线性能。 这种结构的移动宽带产品， 由于天线单独占用较大的一部分空间， 无法使产品体积做的 更小， 对便携性会造成一定影响。 发明内容

所述机壳的腔体用于容置所述电路板组件及电路板组件上设置的电器元件，所述机 壳的腔体的形状与所述电路板组件的形状相适应； 在所述电路板组件沿机壳滑动时， 所 述接口器件能伸出所述接口孔或缩入所述机壳的腔体内部； 其中， 所述电器元件包括所 述接口器件。
由上述本发明实施方式提供的技术方案可以看出，本发明实施方式中通过将天线设 置在机壳内壁， 由天线形成一能够容置收缩装入的电路板组件的中空空间， 使得移动宽 带产品在不使用状态下， 收缩装入机壳内的电路板组件的一部分可装入到天线的中空空 间中， 从而使得天线不再单独占用机壳内的一部分空间， 有效的缩短了移动宽带装置的 体积， 而使用时电路板组件从机壳内滑动拉出一部分， 使得电路板组件拉出天线的中空 空间， 从而使用时也不会影响机壳内的天线性能。 附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实施例或现有 技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本 发明的一些实施例， 对于本领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还 可以根据这些附图获得其他附图。

图 5为本发明实施例提供的移动宽带装置的电路板组件与天线连接的示意图。 具体实肺式 为便于理解， 下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案 进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是全 部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有做出创造性劳动前提 下所获得的所有其他实施例， 都属于本发明保护的范围。
实施例一
本实施例提供一种移动宽带装置， 可用在计算机类产品上， 实现移动宽带连接， 如图 2、 3所示， 该移动宽带装置包括：
机壳 1、 电路板组件 3 (PCBA, Printed Cirruit Board Assembly) 和天线 2; 天线 2与电路板组件 3均设置在机壳 1内，电路板组件 3包括 PCB板 (PCB， Printed Cirruit Board) 和设置在 PCB板上的各种电器元件， 电路板组件 3上的各种电器元件 连接构成实现移动宽带连接的硬件结构，电路板组件 3能沿机壳 1滑动拉出或收缩装入; 天线 2固定设置在机壳 1内侧，天线 2形成一容置收缩装入的电路板组件 3的中空空间 201， 天线 2上设有接触点 223 (参考图 4) ， 该接触点 223与电路板组件 3的馈点 31 (参考图 5 ) 电连接。
上述移动宽带装置中， 天线 2可采用柔性天线或金属天线， 具体可以是： 天线的 一侧贴紧并固定设置在机壳内壁上端，天线的上端环绕设置在壳体内上端形成一中空空 间。 图 4所示为天线结构的一种示例， 所述天线的一侧为扁平结构 221， 所述天线的上 端为一条带结构 222， 该扁平结构 221贴紧设置在机壳 1上端内壁， 扁平结构 221与条 带结构 222电连接， 所述条带结构 222设置在壳体 1上端， 所述条带结构 222呈弧形形 成一中空空间 201。 可以知道， 图 4中是天线结构的一种示例， 天线的一侧也可不采用 扁平结构 221， 而根据机壳内部造型进行设置的、 能紧贴机壳内壁便于固定在机壳内的 形状均可； 同样的， 天线的上端也可不采用条带结构 222， 只要天线的上端与机壳内部 固定该天线的上端的内侧部分垂直或近似垂直以便形成一个中空空间即可。 因此， 根据 本发明的实施例， 天线的结构形式还可以有多种变形， 只要保证该天线设置在机壳内固 定， 且不单独占用空间， 并形成一可容置收缩装入的电路板组件的中空空间即可。
如图 5所示， 天线 2的接触点 223可采用弹性金属体， 该弹性金属体与电路板组 件 3的馈点 31弹性滑动连接。 实际中， 所述机壳上可以设有限位卡件， 电路板组件上 也可以设有定位卡件， 电路板组件上的定位卡件与所述机壳上的限位卡件相对应。 这样 当滑动拉出和收缩装入电路板组件时，机壳上的限位卡件可保证电路板组件在一定的范 围内滑动， 可很好的保持电路板组件 3的馈点 31与天线 2的接触点 223电气连接。
上述移动宽带装置中， 天线贴紧机壳内侧并固定设置在机壳内侧， 天线形成一中 空空间， 在移动宽带装置不使用状态下， 电路板组件可以收缩到该天线的中空空间中， 从而可以有效节省体积， 缩短整个移动宽带装置的长度； 在移动宽带装置使用状态下电 路板组件可以从机壳滑动拉出， 从而电路板组件从机壳内天线所形成的内部空间中拉 出， 此时， 天线的接触点与电路板组件的馈点电气导通， 这样在使用时也不会影响天线 性能。 实施例二

电路板组件 3包括 PCB板 （PCB， Printed Cirruit Board) 和设置在 PCB板上的 各种电器元件， 例如 USB接口 4、 电磁屏蔽罩 5、 处理器等； 电路板组件 3上设有各种 电器元件连接构成实现移动宽带连接的硬件结构， 其中， USB接口 4设置在电路板组件 3的一端， 在机壳上与 USB接口 4相对应的位置开设有接口孔， 接口孔位于机壳 1的一 端， USB接口 4和接口孔位于移动宽带装置的同一端； 电路板组件 3能沿机壳 1滑动， 当电路板组件 3沿机壳 1滑动时， USB接口 4能够伸出接口孔或者缩入机壳 1的腔体内 部；
天线 2与接口孔分别设置在机壳 1的两个对端， 天线 2的形状与机壳 1的腔体内 壁形状相适应， 天线 2上设有接触点 223 (参考图 4) ， 该接触点 223与电路板组件 3 的馈点 31 (参考图 5) 电连接。
需要说明的是， 当 USB接口 4缩入机壳 1的腔体内部时， 如图 3所示， 电路板组 件 3都装入机壳 1的腔体内， 此时， 在至少一个与电路板组件 3的滑动方向相垂直的投 影方向上， 电路板组件 3在机壳 1的腔体内壁上的投影， 与天线 2在机壳 1的腔体内壁 上的投影， 部分或者全部重合。 当 USB接口 4伸出接口孔时， 如图 2所示， 电路板组件 3空出机壳 1 内天线 2所在端的部分腔体空间 201， 此时， 在前述投影方向上， 天线 2 的大部分或者全部与电路板组件 3的投影不重合， 并且伸出接口孔的 USB接口 4可以插 入计算机的 USB接口槽中， 移动宽带装置可以通过 USB接口 4与计算机进行数据传输。 上述移动宽带装置中， 天线 2可采用柔性天线或金属天线。 天线 2可以包括至少 两个部分， 例如： 天线的第一部分贴紧并固定设置在机壳端部的腔体内壁侧面， 天线的 第二部分环绕设置在壳体端部的腔体内壁端面， 该第二部分形成一中空空间， 或者， 该 第一部分和第二部分一起形成一中空空间。 图 4所示为天线结构的一种示例， 天线 2的 第一部分为扁平结构 221， 天线 2的第二部分为条带结构 222， 该扁平结构 221贴紧设 置在机壳 1端部的腔体内壁侧面上， 扁平结构 221电连接条带结构 222， 所述条带结构 222设置在壳体 1端部的腔体内壁端面上， 所述条带结构 222呈弧形并与所述扁平结构 221—起形成一中空空间 201。 可以知道， 图 4中是天线结构的一种示例， 天线的第一 部分也可不采用扁平结构 221， 而采用根据机壳内部造型进行设置的、 能紧贴机壳内壁 侧面便于固定在机壳内的形状， 天线的第二部分也可不采用条带结构， 而采用根据机壳 内部造型进行设置的、 能紧贴机壳内壁端面便于固定在机壳内的形状。 因此， 根据本发 明的实施例， 天线的结构形式还可以有多种变形， 只要保证该天线设置在机壳内固定， 且天线的形状与机壳的腔体内壁形状相适应即可， 此时， 天线不单独占用空间， 并形成 一可容置收缩装入的电路板组件的中空空间。
其中， 上述机壳端部指， 长方体或者条状机壳的一个顶面及靠近该顶面周围的部 分侧面； 上述机壳端部的内壁侧面指， 机壳端部的部分侧面的内壁； 上述机壳端部的内 壁端面指， 机壳端部的顶面的内壁。
如图 5所示， 天线 2的接触点 223可采用弹性金属体， 该弹性金属体与电路板组 件 3的馈点 31弹性滑动连接。 实际中， 所述机壳上可以设有限位卡件， 电路板组件上 也可以设有定位卡件， 电路板组件上的定位卡件与所述机壳上的限位卡件相对应。 这样 当滑动拉出和收缩装入电路板组件时，机壳上的限位卡件可保证电路板组件在一定的范 围内滑动， 可很好的保持电路板组件 3的馈点 31与天线 2的接触点 223电气连接。
上述移动宽带装置中， 天线贴紧机壳内壁并固定设置在机壳内壁上， 天线形成一 中空空间， 在移动宽带装置不使用状态下， 使电路板组件可以收缩到该天线的中空空间 中， 从而可以有效节省体积， 缩短整个移动宽带装置的长度； 在移动宽带装置使用状态 下， 电路板组件上设置的 USB接口可以从机壳滑动拉出， 从而电路板组件从机壳内天线 所形成的内部空间中拉出， 此时， 天线的接触点与电路板组件的馈点电气导通， 这样在 使用时也不会影响天线性能。 综上所述， 本发明实施例中通过将天线设置在机壳内侧， 并使天线形成一中空空 间， 从而可以在移动宽带装置不使用状态下， 使得电路板组件可以收缩到天线的中空空 间中， 可以使移动宽带装置的整机长度再缩短 10mm左右， 可以大大提高移动宽带产品 的体积及便携性。
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。
