背景技术
近年来,随着手机、平板电脑、笔记本电脑等电子设备逐渐向功能更优化、薄型化方向发展,电子设备内天线净空越来越小,布局空间越来越受限。同时又出现了很多新的通信规格,比如5G通信规格,5G移动通信主要基于多输入多输出(multiple-input multiple-output,MIMO)天线系统,MIMO天线系统包括两个或者两个以上的天线单元,相邻两个天线单元之间需保留一定的间距,以保证天线单元之间的隔离度。这种天线系统在电子设备内所需的净空较大,由此阻碍了电子设备向功能更优化、薄型化方向发展。同时,随着电子设备逐渐向机身金属化方向发展,将天线设置于电子设备内部,需要在电子设备的壳体上设置非金属化窗口,由此无法实现电子设备的机身全金属化。

为达到上述目的,本申请一些实施例提供一种电子设备,该电子设备包括显示屏、键盘主机、铰链、电连接件、第一馈电件和第一接地件;显示屏与键盘主机通过铰链可旋转连接;显示屏的壳体和键盘主机的壳体均为金属壳体,显示屏的靠近铰链的边缘与键盘主机的靠近铰链的边缘之间形成主辐射缝隙,电连接件穿过主辐射缝隙将显示屏与键盘主机电连接,第一馈电件和第一接地件设置于主辐射缝隙内,第一馈电件与第一接地件间隔设置,第一馈电件位于第一接地件的远离电连接件的一侧。

当前,天线通常设置于电子设备的内部,尤其是设置于电子设备的主机内部,以利用电子设备的壳体保护天线。但是,在将天线设置于电子设备的内部,一方面,会占用电子设备的内部空间,使电子设备不能向功能更优化和薄型化方向发展;另一方面,将天线设置于电子设备的内部,电子设备的壳体将不能实现全金属化设计。
为了解决上述问题,本申请提供一种电子设备,该电子设备为包括可旋转连接的显示屏和键盘主机的一类电子设备。具体地,电子设备的结构形式包括但不限于笔记本电脑、翻盖手机和翻盖式掌上电脑。
请参阅图1,图1为本申请一些实施例提供的电子设备1的结构示意图。在本实施例中,电子设备1为笔记本电脑。电子设备1包括显示屏11、键盘主机12、铰链13和电连接件14。
显示屏11用于显示图像、视频等。显示屏11可以采用柔性显示屏,也可以采用刚性显示屏。例如,显示屏11可以为有机发光二极管(organic light-emitting diode,OLED)显示屏,有源矩阵有机发光二极体或主动矩阵有机发光二极体(active-matrix organic light-emitting diode,AMOLED)显示屏,迷你发光二极管(mini organic light-emitting diode)显示屏,微型发光二极管(micro organic light-emitting diode)显示屏,微型有机发光二极管(micro organic light-emitting diode)显示屏,量子点发光 二极管(quantum dot light emitting diodes,QLED)显示屏,液晶显示屏(liquid crystal display,LCD)。显示屏11的壳体为金属壳体,显示屏11的壳体的材料包括但不限于镁铝合金和钛合金。
键盘主机12用于输入指令和数据,并根据输入的指令和数据控制显示屏11显示图像、视频。键盘主机12的壳体为金属壳体,键盘主机12的壳体的材料包括但不限于镁铝合金和钛合金。
铰链13用于可旋转连接显示屏11和键盘主机12,以使电子设备在打开状态与闭合状态之间切换。当电子设备处于打开状态时,显示屏11与键盘主机12呈大于90°而小于180°的夹角,且铰链13具有阻尼作用,以使电子设备1能够保持在任意打开角度位置;当电子设备处于闭合状态时,显示屏11盖合于键盘主机12上,且显示屏11的显示面与键盘主机12的键盘面相对。铰链13连接于显示屏11的壳体与键盘主机12的壳体之间,当然,铰链13也可以连接于显示屏11的其他部位与键盘主机12的其他部位之间,在此不做具体限定。
显示屏11的连接铰链13的边缘与键盘主机12的连接铰链13的边缘之间形成主辐射缝隙15,为了形成该主辐射缝隙15,除了显示屏11的壳体和键盘主机12的壳体为金属壳体之外,还可以仅显示屏11的壳体和键盘主机12的壳体在主辐射缝隙15的两侧的部分为金属,或者,显示屏11和键盘主机12中一个的壳体为金属壳体,显示屏11和键盘主机12中另一个的壳体靠近主辐射缝隙15的部分为金属,在此不作具体限定。
电连接件14穿过主辐射缝隙15将显示屏11与键盘主机12电连接,以使键盘主机12能够控制显示屏11显示图像、视频。电连接件14包括但不限于电连接线缆和电连接弹片,且电连接件14可以穿过主辐射缝隙15的中部,也可以穿过主辐射缝隙15的边缘,在此不作具体限定。电连接件14经过主辐射缝隙15的部分可以隐藏在铰链13内或者主辐射缝隙15的遮挡件内。
在本申请实施例中,通过在该主辐射缝隙15内设置馈电件和接地件,并合理布局馈电件和接地件相对于电连接件14的位置,可以形成至少一个缝隙天线,电子设备通过该至少一个缝隙天线可以实现与外界信号的通信。
请参阅图2,图2为本申请一些实施例提供的电子设备内馈电件和接地件的一种位置示意图。电子设备1还包括第一接地件16和第一馈电件17。第一接地件16和第一馈电件17设置于主辐射缝隙15内,且第一接地件16与第一馈电件17间隔设置,第一馈电件17位于第一接地件16的远离电连接件14的一侧。
这样,显示屏11的壳体、键盘主机12的壳体、第一接地件16和第一馈电件17形成第一缝隙天线。定义主辐射缝隙15沿自身长度方向(也即是图2中的方向X)的两端分别为第一端A和第二端B,第一端A和第一馈电件17位于第一接地件16的同一侧,第一缝隙天线的长度为第一接地件16至第一端A的距离(也即是图2中的距离D1)。第一缝隙天线的长度需满足远大于主辐射缝隙15的宽度(也即是图2中的距离d)的条件,其中,由于电子设备1通常在处于“打开状态”时,才会开机使用并通过天线收发信号,因此辐射缝隙15的宽度是指电子设备1处于“打开状态”时,辐射缝隙15的宽度。在满足此条件的基础上,第一缝隙天线的长度D1近似等于第一缝隙 天线的谐振波长的1/4倍,通过设计第一接地件16的位置,可以得到具有相应谐振频率的第一缝隙天线。
在图2中未示出铰链13,具体地,铰链13可以与第一接地件16为同一结构件,也可以与第一馈电件17为同一结构件,还可以与第一接地件16、第一馈电件17分别为独立的结构件,在此不作具体限定。具体地,铰链13的结构参杂在以下第一接地件16和第一馈电件17的各个实施例中进行介绍。
第一接地件16用于接地。由于电子设备1的壳体(包括显示屏11的壳体和键盘主机12的壳体)与电子设备1内的电路板的参考地层通常是共地连接的,因此,第一接地件16可以通过线缆、弹片等接地连接件与键盘主机12内电路板的金属参考地层电连接以实现接地,也可以直接与显示屏11的壳体和/或键盘主机12的壳体电连接以实现接地,在此不做具体限定。
在一些实施例中,第一接地件16沿主辐射缝隙15的宽度方向(也即是图2中的方向Y)横跨在主辐射缝隙15内,且第一接地件16的一端与显示屏11的壳体连接并电导通,第一接地件16的另一端与键盘主机12的壳体连接并电导通,由此第一接地件16通过与显示屏11的壳体和键盘主机12的壳体直接连接实现了接地。此接地方式无需设置接地连接件,因此结构简单。
第一接地件16和铰链13均位于主辐射缝隙15内,第一接地件16可以与铰链13为同一结构件,也可以独立于铰链13之外,在此不做具体限定。
在一些实施例中,请参阅图3a和图3b,图3a为本申请一些实施例提供的电子设备内第一接地件和铰链的一种相对位置示意图,图3b为图3a中区域I的立体图。铰链13包括第一铰链131,第一铰链131整体的材料为锌合金、钢、铁、不锈钢等金属导电材料或者非金属半导体材料,第一铰链131构成第一接地件16。这样,第一接地件16和第一铰链131为同一结构件,能够减少电子设备的组成结构件的数量,降低电子设备的结构复杂度。在此基础上,为了实现第一铰链131的接地,可选地,第一铰链131的连接显示屏11的一端与显示屏11的壳体连接并电导通,第一铰链131的连接键盘主机12的一端与键盘主机12的壳体连接并电导通,此结构简单,容易实现。
在另一些实施例中,第一接地件16独立于铰链13之外。在此基础上,第一接地件16的结构形式以及第一接地件16与显示屏11之间、第一接地件16与键盘主机12之间的连接方式应满足不影响显示屏11与键盘主机12之间相对转动的条件。为了满足此条件:示例地,第一接地件16可以为柔性金属导体,比如为金属丝线,第一接地件16的一端与显示屏11连接,第一接地件16的另一端与键盘主机12连接,这样,第一接地件16能够产生弯曲变形以允许显示屏11相对于键盘主机12转动。又示例地,第一接地件16为刚性金属导体,第一接地件16的一端固定于键盘主机12,第一接地件16的另一端与显示屏11通过圆弧面可旋转接触,该圆弧面对应的圆心线与铰链13的旋转轴线共线,这样,显示屏11在相对于键盘主机12转动的同时,也相对于第一接地件16转动,因此第一接地件16不影响显示屏11与键盘主机12之间相对转动。
第一接地件16独立于铰链13之外,具体地,铰链13可以位于第一接地件16的靠近第一端A的一侧,也可以位于第一接地件16的靠近第二端B的一侧,在此不作具体限定。需要说明的是,当铰链13位于第一接地件16的靠近第二端B的一侧时, 铰链13无论是导电件还是绝缘件,均不会对第一缝隙天线产生影响。
请参阅图4a和图4b,图4a为本申请一些实施例提供的电子设备内第一接地件和铰链的另一种相对位置示意图,图4b为图4a中区域II的立体图。铰链13包括第一铰链131,第一铰链131和第一馈电件17位于第一接地件16的同一侧,也即是,第一铰链131位于第一接地件16的靠近第一端A的一侧,或者,第一铰链131直接位于第一端A。图4a和图4b仅给出了第一铰链131位于第一端A的示例,并不能认为是对本申请构成的特殊限定。第一铰链131整体的材料为塑胶、陶瓷等绝缘材料。或者,第一铰链131包括第一导电部分、第二导电部分和绝缘部分,第一铰链131的第一导电部分与显示屏11的壳体连接,第一铰链131的第二导电部分与键盘主机12的壳体连接,第一导电部分与第二导电部分间隔开一定距离并通过绝缘部分连接。这样,第一铰链131未将显示屏11的壳体与键盘主机12的壳体电连接,第一铰链131不会封闭第一缝隙天线的辐射口(也即是主辐射缝隙的第一端A处的开口),使得第一缝隙天线的信号能够由该辐射口辐射出去。
其中,具体地,该绝缘部分可以为第一铰链131的转轴、轴套以及转轴和/或轴套中的部分,只要绝缘部分能够阻断显示屏11的壳体与键盘主机12的壳体之间通过第一铰链131电导通的路径即可,在此不做具体限定。
请参阅图5a和图5b,图5a为本申请一些实施例提供的电子设备内第一铰链的立体图,图5b为图5a所示第一铰链的爆炸图。第一铰链131包括转轴1311、第一轴套1312和第二轴套1313。转轴1311包括材料为金属材料的转轴主体1311a和设置于该转轴主体1311a的侧壁一周的绝缘材料层1311b,绝缘材料层1311b的材料包括但不限于塑胶、橡胶和硅胶,绝缘材料层1311b可以通过涂覆、胶黏、套设等方式固定于转轴主体1311a的侧壁一周,绝缘材料层1311b和转轴主体1311a共同构成第一铰链131的绝缘部分,转轴1311沿自身长度方向划分为第一区段和第二区段。第一轴套1312和第二轴套1313的材料为金属材料,第一轴套1312构成第一铰链131的第一导电部分,第二轴套1313构成第一铰链131的第二导电部分。第一轴套1312与显示屏11的壳体连接,在一些实施例中,第一轴套1312具有第一翼部1312a,第一轴套1312通过第一翼部1312a与显示屏11的壳体连接,可选地,第一翼部1312a与显示屏11的壳体之间设有第一垫板1312b。第二轴套1313与键盘主机12的壳体连接,在一些实施例中,第二轴套1313具有第二翼部1313a,第二轴套1313通过第二翼部1313a与键盘主机12的壳体连接,可选地,第二翼部1313a与键盘主机12的壳体之间设有第二垫板1313b。第一轴套1312配合套设于转轴1311的第一区段上,第二轴套1313配合套设于转轴1311的第二区段上,第一轴套1312、第二轴套1313沿转轴1311的轴向间隔设置。这样,通过绝缘材料层1311b将转轴1311绝缘化,能够在保证转轴1311的结构强度的基础上,使转轴1311与第一轴套1312之间、以及转轴1311与第二轴套1313之间绝缘,同时由于第一轴套1312、第二轴套1313沿转轴1311的轴向间隔设置,因此第一轴套1312与第二轴套1313之间绝缘,其中,绝缘材料层1311b和转轴主体1311a共同构成第一铰链131的绝缘部分,该绝缘部分能够阻断显示屏11的壳体与键盘主机12的壳体之间通过第一铰链131电导通的路径,以防止第一铰链131封闭第一缝隙天线的辐射口。此结构简单,容易实现。
在上述实施例中,需要说明的是,绝缘材料层1311b的材料为橡胶、硅胶等弹性材料,在此基础上,第一轴套1312和第二轴套1313的内径可以设计为比转轴1311在绝缘材料层1311b处于自由状态时的外径小,这样,在将第一轴套1312和第二轴套1313套设于转轴1311上时,将会挤压绝缘材料层1311b以使其产生弹性形变,绝缘材料层1311b因形变产生的弹性力可以阻止第一轴套1312和第二轴套1313相对于转轴1311旋转,由此形成了具有阻尼作用的第一铰链131,以使电子设备1能够保持在任意打开角度位置。
请继续参阅图2,第一馈电件17用于向主辐射缝隙15馈电。第一馈电件17可以为直接馈电结构,也可以为耦合馈电结构。为了实现第一缝隙天线与键盘主机12内射频前端的阻抗匹配,当第一馈电件17为直接馈电结构时,第一馈电件17靠近第一参考地16设置,当第一馈电件17为耦合馈电结构时,第一馈电件17靠近第一缝隙天线的辐射口(也即是主辐射缝隙15的第一端A处的开口)设置或者直接位于第一缝隙天线的辐射口处。具体地,第一馈电件17的结构实现方式可以包括以下六种实现方式:
第一种实现方式:请参阅图6,图6为本申请一些实施例提供的电子设备中第一馈电件的结构示意图。第一馈电件17为设置于显示屏11与键盘主机12之间的导电件。第一馈电件17的靠近显示屏11的一端与显示屏11的壳体电连接,第一馈电件17的靠近键盘主机12的一端与键盘主机12的壳体绝缘。键盘主机12包括第一射频前端,第一射频前端通过同轴线、微带线等馈电结构17a与第一馈电件17的靠近键盘主机12的一端电连接。在一些实施例中,第一射频前端包括发射通路和接收通路。发射通路包括功率放大器、滤波器等器件,通过功率放大器、滤波器等器件将信号进行功率放大、滤波等处理后由第一馈电件17传输至显示屏11的壳体,并经显示屏11的壳体传输至外界;接收通路包括低噪声放大器、滤波器等器件,通过低噪声放大器、滤波器等器件将显示屏11的壳体接收到的外界信号进行低噪声放大、滤波等处理后传输至射频芯片,从而通过显示屏11的壳体、第一馈电件17和第一射频前端实现电子设备与外界信号的通信。第一射频前端设置于键盘主机12的壳体内,且第一射频前端可以集成在键盘主机12内的主板上,也可以为独立于主板之外,在此不做具体限定。此第一馈电件17的结构形式为直接馈电结构,结构简单,容易实现。
在上述实施例中,第一馈电件17需满足不影响显示屏11与键盘主机12之间相对转动的条件。为了满足此条件:示例地,第一馈电件17为柔性金属线,柔性金属线易于弯曲变形,不影响显示屏11与键盘主机12之间相对转动。
又示例地,第一馈电件17为刚性结构,此时,第一馈电件17的靠近显示屏11的一端与显示屏11的壳体固定,第一馈电件17的靠近键盘主机12的一端与键盘主机12之间保持一定的避让间隙,该避让间隙能够避免第一馈电件17在随着显示屏11一起相对于键盘主机12转动时,与键盘主机12发生触碰,同时该避让间隙能够实现第一馈电件17与键盘主机12的壳体之间的绝缘。
还示例地,请参阅图7,图7为本申请又一些实施例提供的电子设备中第一馈电件的结构示意图。铰链13包括第一铰链131。第一铰链131和第一馈电件17位于第一接地件16的同一侧。第一铰链131整体的材料为锌合金、钢、铁、不锈钢等金属导电材料或者非金属半导体材料。第一铰链131的连接显示屏11的一端与显示屏11的 壳体连接并电导通。第一铰链131的连接键盘主机12的一端与键盘主机12的壳体绝缘连接。“绝缘连接”是指两者连接在一起,但两者之间不电流导通。在一些实施例中,第一铰链131的连接键盘主机12的一端与键盘主机12的壳体之间垫设有绝缘垫片,且第一铰链131的连接键盘主机12的一端、绝缘垫片和键盘主机12的壳体之间通过绝缘螺栓等绝缘连接件连接在一起,由此实现了第一铰链131的连接键盘主机12的一端与键盘主机12的壳体之间的绝缘连接。第一铰链131构成第一馈电件17。这样,第一馈电件17和第一铰链131为同一结构件,不仅不影响显示屏11与键盘主机12之间相对转动,还能够减少电子设备的组成结构件的数量,降低电子设备的结构复杂度。
第二种实现方式:请参阅图8,图8为本申请又一些实施例提供的电子设备中第一馈电件的结构示意图。第一馈电件17为设置于显示屏11与键盘主机12之间的导电件。第一馈电件17的靠近显示屏11的一端与显示屏11的壳体绝缘,第一馈电件17的靠近键盘主机12的一端与键盘主机12的壳体电连接。键盘主机12包括第一射频前端,第一射频前端通过同轴线、微带线等馈电结构17a与第一馈电件17的靠近显示屏11的一端电连接。在一些实施例中,该馈电结构17a由键盘主机12引出,并穿过第一接地件16的远离第一馈电件17的一侧的主辐射缝隙15,伸入显示屏11的壳体内,并进一步由显示屏11的壳体的靠近第一馈电件17的位置伸出,以与第一馈电件17的靠近显示屏11的一端电连接。在一些实施例中,馈电结构17a穿过主辐射缝隙15的部分可以与电连接件14一起隐藏在位于第一接地件16的远离第一馈电件17的一侧的铰链13内或者主辐射缝隙15的遮挡件内。这样,第一射频前端向第一馈电件17的靠近显示屏11的一端馈入射频信号,并通过第一馈电件17将射频信号传输至键盘主机12的壳体,以通过键盘主机12的壳体将射频信号辐射至外界环境中,第一射频前端还用于接收键盘主机12的壳体接收到的射频信号。此第一馈电件17的结构形式为直接馈电结构,结构简单,容易实现。
在上述实施例中,第一馈电件17同样需要满足不影响显示屏11与键盘主机12之间相对转动的条件。为了满足此条件:
示例地,第一馈电件17为柔性金属线,柔性金属线易于弯曲变形,不影响显示屏11与键盘主机12之间相对转动。
又示例地,第一馈电件17为刚性结构,此时,第一馈电件17的靠近键盘主机12的一端与键盘主机12的壳体固定,第一馈电件17的靠近显示屏11的一端与显示屏11之间保持一定的避让间隙,该避让间隙能够避免显示屏11在相对于键盘主机12和第一馈电件17转动时,与第一馈电件17发生触碰,同时该避让间隙能够实现第一馈电件17与显示屏11的壳体之间的绝缘。
还示例地,请参阅图9,图9为本申请又一些实施例提供的电子设备中第一馈电件的结构示意图。铰链13包括第一铰链131。第一铰链131和第一馈电件17位于第一接地件16的同一侧。第一铰链131整体的材料为锌合金、钢、铁、不锈钢等金属导电材料或者非金属半导体材料。第一铰链131的连接键盘主机12的一端与键盘主机12的壳体连接并电导通。第一铰链131的连接显示屏11的一端与显示屏11的壳体绝缘连接。在一些实施例中,第一铰链131的连接显示屏11的一端与显示屏11的壳体 之间垫设有绝缘垫片,且第一铰链131的连接显示屏11的一端、绝缘垫片和显示屏11的壳体之间通过绝缘螺栓等绝缘连接件连接在一起,由此实现了第一铰链131与显示屏11的壳体之间的绝缘连接。第一铰链131构成第一馈电件17。这样,第一馈电件17和第一铰链131为同一结构件,不仅不影响显示屏11与键盘主机12之间相对转动,还能够减少电子设备的组成结构件的数量,降低电子设备的结构复杂度。

为了增大第一缝隙天线的带宽,可以在主辐射缝隙15的位于第一接地件16与第一端A之间的部分上设置寄生辐射缝隙或者寄生辐射枝节,以增加第一缝隙天线的谐振点。具体地:
在一些实施例中,请参阅图27,图27为本申请又一些实施例提供的电子设备中第一缝隙天线的结构示意图。显示屏11包括转轴盖111。转轴盖111连接于显示屏11的壳体上,且转轴盖111位于铰链13的外侧。其中,铰链13的外侧是指铰链13的远离第一区域的一侧,所述第一区域为显示屏11的显示面与键盘主机12的键盘表面之间的夹角区域。转轴盖111用于在电子设备处于“闭合状态”时,覆盖于键盘主机12的侧面上,以遮盖铰链13以及显示屏11与键盘主机12之间的连接缝隙。转轴盖111的材料为导电材料,在一些实施例中,转轴盖111的材料为金属导电材料。转轴盖111与显示屏11的壳体电导通,主辐射缝隙15形成于转轴盖111的远离显示屏11的壳体的边缘与键盘主机12的靠近铰链13的边缘之间。转轴盖111上设有至少一个寄生辐射缝隙18,至少一个是指一个或者两个以上的数量,图15仅示出寄生辐射缝隙18的数量为两个的示例。寄生辐射缝隙18的一端封闭,寄生辐射缝隙18的另一端与主辐射缝隙15连通。该至少一个寄生辐射缝隙18和第一馈电件17位于第一接地件16的同一侧。这样,寄生辐射缝隙18为第一缝隙天线中除主辐射缝隙之外的增加的寄生辐射缝隙,因此能够增加第一缝隙天线的谐振点的数量,增大第一缝隙天线的带宽。
在上述实施例中,寄生辐射缝隙18可以为直线型缝隙、L型缝隙等等,图30仅 给出了寄生辐射缝隙18为L型缝隙的示例,并不能认为是对本申请构成的特殊限定。
请参阅图28,图28为图27所示的第一缝隙天线的输入回波损耗图和系统效率图。图28的横坐标为频率(单位为GHz),纵坐标为输入回波损耗系数(单位为dB),S11表示第一缝隙天线的输入回波损耗。从图28中可以看出,第一缝隙天线具有多个谐振点,且多个谐振点处的系统效率满足需求,因此带宽较大,能够满足MHB天线、5G天线、Sub-6G天线的需求。
在又一些实施例中,请参阅图29,图29为本申请又一些实施例提供的电子设备中第一缝隙天线的结构示意图。显示屏11包括转轴盖111。转轴盖111连接于显示屏11的壳体上,且转轴盖111位于铰链13的外侧。其中,铰链13的外侧是指铰链13的远离第一区域的一侧,所述第一区域为显示屏11的显示面与键盘主机12的键盘表面之间的夹角区域。转轴盖111用于在电子设备处于“闭合状态”时,覆盖于键盘主机12的侧面上,以遮盖铰链13以及显示屏11与键盘主机12之间的连接缝隙。转轴盖111的材料为绝缘材料,主辐射缝隙15形成于显示屏11的壳体与键盘主机12的壳体之间。在此基础上,转轴盖111上设有至少一个第一寄生辐射枝节19,至少一个是指一个或者两个以上的数量,图32仅示出第一寄生辐射枝节19的数量为两个的示例。第一寄生辐射枝节19的接地端与显示屏11的壳体相接,至少一个第一寄生辐射枝节19和第一馈电件17位于第一接地件16的同一侧。这样,第一寄生辐射枝节19为第一缝隙天线中除主辐射缝隙之外的增加的寄生辐射枝节,因此能够增加第一缝隙天线的谐振点的数量,增大第一缝隙天线的带宽。
在上述实施例中,第一寄生辐射枝节19可以为直线型枝节、L型枝节、F型枝节等等,图29仅给出了第一寄生辐射枝节19为L型枝节的示例,并不能认为是对本申请构成的特殊限定。
在又一些实施例中,请参阅图30,图30为本申请又一些实施例提供的电子设备中键盘主机的朝向主辐射缝隙的表面结构示意图。键盘主机12的朝向主辐射缝隙15的表面设有凹槽20,该凹槽20的侧壁和底壁属于键盘主机12的壳体,凹槽20内设有至少一个第二寄生辐射枝节21,至少一个是指一个或者两个以上的数量,图33仅示出凹槽20内设置的第二寄生辐射枝节21的数量为两个的示例。第二寄生辐射枝节21的接地端与凹槽20的侧壁或者底壁连接,至少一个第二寄生辐射枝节21和第一馈电件17位于第一接地件16的同一侧。这样,第二寄生辐射枝节21为第一缝隙天线中除主辐射缝隙之外的增加的寄生辐射枝节,因此能够增加第一缝隙天线的谐振点的数量,增大第一缝隙天线的带宽。且第二寄生辐射枝节21设置于凹槽20内,能够避免第二寄生辐射枝节21凸出键盘主机12的外表面而与显示屏11之间产生干涉。
第二寄生辐射枝节21可以沿平面直线或者折线延伸,也可以沿三维折线延伸,在此不做具体限定。在一些实施例中,第二寄生辐射枝节21沿平面直线或者折线延伸,且第二寄生辐射枝节21所处的平面与凹槽20的底壁平行,第二寄生辐射枝节21的接地端与凹槽20的侧壁连接。这样,可以减小凹槽20的开设深度。
在上述实施例中,第二寄生辐射枝节21可以为直线型枝节、L型枝节、F型枝节等等,图30仅给出了第二寄生辐射枝节21为F型枝节的示例,并不能认为是对本申请构成的特殊限定。
请参阅图31,图31为图30所示键盘主机沿A-A向的截面结构示意图。电子设备还包括介电板22,介电板22包括相对的第一表面221和第二表面222,介电板22设置于凹槽20内,且介电板22的第一表面221与凹槽20的底壁贴合,第二寄生辐射枝节21设置于介电板22的第二表面222上,具体地,第二寄生辐射枝节21可以为设置于第二表面222上的金属层,也可以为设置于第二表面222上的金属片。此结构简单,容易制作。
请参阅图32,图32为图30和图31所示的第一缝隙天线的输入回波损耗图和系统效率图。图32的横坐标为频率(单位为GHz),纵坐标为输入回波损耗系数(单位为dB),S11表示第一缝隙天线的输入回波损耗。从图32中可以看出,第一缝隙天线具有多个谐振点,且多个谐振点处的系统效率满足需求,因此带宽较大,能够满足MHB天线、5G天线、Sub-6G天线的需求。
请参阅图33,图33为本申请又一些实施例提供的电子设备的结构示意图。电子设备除了包括第一馈电件17和第一接地件16之外,还包括第二馈电件23和第二接地件24。第二馈电件23和第二接地件24设置于主辐射缝隙15内,且第二馈电件23与第二接地件24间隔设置,第二接地件24和第一接地件16分别位于电连接件14的相对两侧,第二馈电件23位于第二接地件24的远离电连接件14的一侧。
这样,显示屏11的壳体、键盘主机12的壳体、第二接地件24和第二馈电件23形成第二缝隙天线。第二端B和第二馈电件23位于第二接地件24的同一侧,第二缝隙天线的长度为第二接地件24至第二端B的距离(也即是图33中的距离D2)。第二缝隙天线的长度需满足远大于主辐射缝隙15的宽度的条件。在满足此条件的基础上,第二缝隙天线的长度近似等于第二缝隙天线的谐振波长的1/4倍,通过设计第二接地件24的位置,可以得到具有相应谐振频率的第二缝隙天线。
第二缝隙天线的结构形式可以与上述任一实施例所述的第一缝隙天线的结构形式相同,在此不做赘述。
第一缝隙天线和第二缝隙天线可以组成MIMO天线或者双低频天线,第一缝隙天线和第二缝隙天线位于主辐射缝隙15的两端,第一缝隙天线和第二缝隙天线之间的距离较远,隔离度较高。
请参阅图34,图34为本申请又一些实施例提供的电子设备的结构示意图。第一接地件16和第二接地件24均与图3b所示电子设备中的第一接地件16的结构形式相同,第一馈电件17和第二馈电件23均与上述第一种实现方式所述的第一馈电件17的结构形式相同。请参阅图35,图35为图34所示的第一缝隙天线和第二缝隙天线的输入回波损耗图。图35的横坐标为频率(单位为GHz),纵坐标为输入回波损耗系数(单位为dB)。S11表示第一缝隙天线的输入回波损耗,S22表示第二缝隙天线的输入回波损耗,S12表示第一缝隙天线与第二缝隙天线之间的隔离度。从图35中可以看出,第一缝隙天线与第二缝隙天线之间的隔离度在-23dB以下,隔离度较大,满足使用要求。
本申请实施例提供的电子设备利用显示屏与键盘主机之间的缝隙形成至少一个一端开口的缝隙天线,可以获得1/4波长天线,无需占用电子设备的内部空间,因此不阻碍电子设备向功能更优化、薄型化、机身全金属化方向发展。
在本说明书的描述中,具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
最后应说明的是:以上实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
