在一些实施例中，每一传导线L1均为柔性传导线，而可随意弯折，从而在滑动座12滑出或滑进本体11时，都能保持天线体T11与对应的射频收发电路3之间的稳定连接，而实现良好电连接。其中，所述传导线L1可为同轴线缆或柔性电路板等。

在另一些实施例中，所述至少一个匹配电路35设置于滑动座12上，且与同样设置于滑动座12上的天线体T11通过传导线L1或其他走线电连接。所述至少一个匹配电路35并通过传导线L1与设置于主电路板2上的射频收发电路3电连接。即，在另一实施例中，所述传导线L1具体为电连接匹配电路 35与对应的射频收发电路3之间。每一天线体T1与匹配电路35电连接后，再通过对应的传导线L1与对应的射频收发电路3电连接。
其中，图2-5中仅示意出部分匹配电路35和射频收发电路3，显然，匹配电路35和射频收发电路3的数量可分别等于电子装置100包括的天线体T1的数量。或者，匹配电路35和射频收发电路3的数量可小于电子装置100包括的天线体T1的数量，即，相同频段的天线体T11可连接至同一匹配电路35和射频收发电路3。
其中，如图2-5所示，所述电子装置100还包括电池4，所述电池4和所述主电路板2电连接，用于为主电路板2及主电路板2上的射频收发电路3等功能器件供电。
请一并参阅图8，为电子装置100的整体外观示意图。如图8所示，所述电子装置100还包括显示模组5。显示模组5覆盖于壳体1背离滑动座12的一侧。其中，图8同样为电子装置100处于第二状态时的示意图。
请一并参阅图9，为电子装置100的分解示意图。如图9所示，显示模组5与壳体1的本体11包围形成内腔101，该内腔101用于收纳所述主电路板2、电池4等元件。如图8所示，显示模组5包括显示区501和非显示区502。显示区501用于显示图像，非显示区502可以是设于显示区501周侧的油墨区或塑胶框等。
其中，所述显示模组5可为LCD(liquid crystal display，液晶)显示面板、OLED(organic light-emitting diode，有机发光二极管)显示面板等。在一些实施例中，所述显示模组5为集成了触摸面板的触控显示面板。
如图8或9所示，所述显示模组5的尺寸可大致等于所述壳体1的本体11。
由于前述的天线体T11为设置于可滑出的滑动座12上，当滑动座12滑出时，位于滑动座12上的天线体T11将远离所述显示模组5，因此，显示模组5的显示区501可设置得尽量大，无需担心对天线的性能造成影响，而可有效提升屏占比。
请参照图10，为壳体1的本体11的背面示意图，所述本体11包括背板110以及从背板110的边沿朝垂直于背板110的方向延伸出来的四个侧壁120。所述四个侧壁120为从背板110朝着垂直背板110的方向延伸一定高度的侧框。所述背板110包括相对设置的第一面F1和第二面F2，所述第一面F1为本体11的外表面。所述显示模组5可以贴合于第二面F2，并与四个侧壁120配合而形成封闭结构。所述四个侧壁120包括第一侧壁S1、第二侧壁S2、第三侧壁S3及第四侧壁S4。第一侧壁S1与第二侧壁S2相对设置。第三侧壁S3与第四侧壁S4相对设置。第三侧壁S3和第四侧壁S4连接在第一侧壁S1和第二侧壁S1之间。背板110上设有缺口K1，缺口K1在背板110上沿切割线G1切割，并沿垂直于第一面F1的从第一面F1到第二面F2的方向深入切割第一预设距离，及在第三侧壁S3上沿切割线G2切割，并沿平行于所述第一面F1的从第三侧壁S3到第四侧壁S4的方向深入切割第二预设距离，两个切割面相交后去除切掉的部分形成壳体1的本体11。在第一面F1和在第三侧壁S3上形成的切割线G1和G2可以是直线、折线或曲线。
其中，所述第一预设距离大于第一面F1到第二面F2的长度而小于侧壁120的宽度(即侧壁120从背板120上垂直延伸的高度)，所述第二预设距离小于第三侧壁S3到第四侧壁S4的距离。
即，如图10所示，所述缺口K1为贯穿所述所述第一侧壁S1、第二侧壁S2、第三侧壁S3这三个相邻侧壁120的部分区域，而形成台阶状的结构。通过在所述本体11上形成有贯穿相邻的三个侧壁120的部分区域的缺口，所述缺口处剩余的第一侧壁S1、第二侧壁S2、第三侧壁S3的部分构成所述延伸部112。
在其他实施例中，请参照图11，所述本体11的背板110具有一个缺口K2，缺口K2可以是在背板110上沿第一切割线G1切割，并沿垂直于第一面F1的第一方向深入切割一次，及在背板110上沿第二切割线G2切割，并沿垂直于第一面F1的第二方向深入切割两次，在第三侧壁S3上沿第一切割线G1切割，并沿平行于第一面F1的第三方向深入切割一次。四次切割的面相交后去除切掉的部分形成壳体1的本体11。在背板110和在第三侧壁S3上形成的切割线可以是直线或折线或曲线。其中，所述第一方 向、第二方向及第三方向形成的切割面相互垂直。如图11所示，在其他实施例中形成的缺口K2为仅贯穿背板110和第三侧壁S3的部分区域的缺口。
请参阅图12，为一实施例中的滑动座12的示意图。如图12所示，滑动座12包括背板121及半包围于背板121的边框122。当滑动座12收容于本体11中时，背板121的外表面与本体11的第一面F1相拼接，背板121的内表面N1与本体11的第二面F2相拼接，从而滑动座12的背板120与所述本体11的背板110相拼接。边框122的外表面与本体11的侧壁120的外表面相拼接。背板121与边框122包围形成收容腔123。收容腔123可用以收容电路板及电子元件等。
如图12所示，设置于滑动座12上的天线体T11为固定设置于所述滑动座12的背板121的内表面N1上，且每一个天线体T11与对应的传导线L1电连接，所述传导线L1可通过所述收容腔123延伸至主电路板2上，并与主电路板2上的相应的射频收发电路3电连接。
其中，如图12所示，在一实施例中，所述收容腔123内还可设置有辅电路板125，所述辅电路板125上可承载有摄像头、传感器、受话器等功能器件126。其中，所述辅电路板125与设置于滑动座12上的所述天线体T11间隔一定距离，以确保不影响天线体T11的辐射性能。在一些实施例中，所述辅电路板125为设置于背板121的内表面N1上。
其中，辅电路板125可以通过螺接、粘结等方式固定在滑动座12的背板121或边框202上。其中，辅电路板125可以是柔性电路板或硬质印刷电路板。当所述滑动座12收容于壳体1的本体11中时，所述设置于滑动座12上的天线体T11以及所述辅电路板12及功能器件126都将被显示模组5遮盖。
其中，所述辅电路板125也可通过传导线L1与主电路板2电连接，而从主电路板2上接收供电电源或者接收控制指令等。
当所述滑动座12滑出本体11时，设置于滑动座12上的天线体T11和功能器件126则将伸出显示模组5之外，而裸露在外面，从而可以有效提升天线体T11的净空区域，并可使得功能器件126处于可使用的状态，例如，可进行拍照、声音输入、进行亮度、动作等相应参数的感应等等。
请一并参阅图13及图14，图13为另一实施例中的滑动座12的示意图，如图13所示，在另一实施例中，所述滑动座12与背板121相对的一面上还设置有封盖板B0，所述封盖板B0用于当滑动座12滑出本体11时起到装饰面的作用，用于当滑动座12滑出本体11时对滑动座12内的结构进行遮蔽。
另外，所述封盖板B0上还可设置有摄像头孔、受话器孔、传感器孔等功能孔Y1，如图14所示，当所述滑动座12滑出本体11时，设置于滑动座12上的天线体T11和功能器件126则将伸出显示模组5之外，从而可以有效提升天线体T11的净空区域，所述设置于辅电路板12上的功能器件126通过相应的功能孔Y1外露而可实现相应的功能。
其中，当所述辅电路板125为设置于滑动座12的背板121的内表面N1上时，与滑动座12上的某一天线体T11电连接的传导线L1在经过辅电路板125时，可为从辅电路板125的上方经过。
从而，当将摄像头、传感器、受话器等功能器件126也设置于滑动座12中，而通过滑出来进行使用时，所述显示模组5的显示区域501可以几乎与壳体1的本体11的四个侧壁120紧贴，可以做到几乎百分之百的屏占比，极大地提高了屏占比。
请参阅图15，为一实施例中的电子装置100的横截面示意图，壳体1的本体11上贴合于滑动座12的面为密封面17。密封面17隔离于壳体1内部与外界环境。密封面17上开设有开孔17a。开孔17a用于穿过电连接滑动座12上的天线体T11与射频收发电路3之间的传导线L1，以避免电连接天线体T11与射频收发电路3之间的传导线L1布局错乱，在滑动座12滑动的过程中，避免传导线L1缠绕于其他电子元件，干扰电子元件的正常工作，提高电子装置100的稳定性。
进一步地，如图15所示，滑动座12上具有与密封面17相贴合的对接面25。从而，当滑动座12还设置有封盖板B0时，所述对接面25、封盖板B0、背板121以及边框122构成四面封闭的收容腔。其中，对接面25上设有连接杆26。壳体1的本体11内设有驱动件18。连接杆26通过开孔17a并连接于驱动件18。驱动件18用于驱动连接杆26伸出或缩回，以使连接杆26推动滑动座12远离或靠近主体部111，连接杆26的设置为滑动座12提供支撑力，并能确保滑动座12平稳滑出或缩回。
进一步地，如图15所示，连接杆26内设有穿孔26a。穿孔26a沿连接杆26延伸的方向延伸。穿孔26a用于穿过电连接天线体T1与射频收发电路3之间的传导线L1，穿孔26a的设置可以避免传导线L1缠绕于其他电子元件，干扰电子元件的正常工作，提高电子装置100的稳定性，同时穿孔26a设于连接杆26内，节省了线缆321的占据空间。
请参阅图16，为另一实施例中的电子装置100的横截面示意图。如图16所示，滑动座12的内部与本体11的主体部111的内部相连通，当滑动座12收容于本体11中时，滑动座12与本体11整体构成一具有内凹空间的壳体，所述传导线L1直接电连接于天线体T1与射频收发电路3之间。换而言之，壳体1的本体11与滑动座12的贴合的面上设有缺口102，且缺口102的边沿靠近于贴合面的边沿，进一步地，缺口102的边沿与贴合面的边沿之间可以是壳体1的壁厚。滑动座12上与壳体1的贴合面与壳体1上与滑动座12的贴合面的结构相对应，以使滑动座12上与壳体1盖合形成较大的容置空间，用于容置主电路板2、电池4等。此外，滑动座12与壳体1的本体11之间的对接窗口较大，可以给予连接于主电路板2与辅电路板125的结构件(如连接杆、FPC、传导线L1)更多的活动空间，以便于电子装置100的滑动座12顺利滑出及滑动座12上的天线体T11或功能器件126正常工作。
请一并参照图17及图18，为电子装置100的示意出滑动机构6的横截面示意图。如图17所示，电子装置100还包括连接于壳体1的本体11与滑动座12之间的滑动机构6。滑动座12通过滑动机构6相对于本体11滑动而靠近或远离本体11。具体的，滑动机构6为实现滑动座12直线运动的运动机构，具体为实现滑动座12沿电子装置100的长度方向滑动的运动机构。本实施例中，滑动机构6可以为滑块与导轨的配合结构、涡轮与蜗杆的配合结构等。本实施例中，滑动机构6包括滑块61与导轨62，导轨62设于延伸部112上。导轨62自主体部111至延伸部112的方向延伸，滑块61可以固定于滑动座12上。滑块61在导轨62上滑动，以带动滑动座12沿导轨62滑动。
具体的，所述滑块61为设置于滑动座12的与延伸部112的延伸方向相同的边框122正对所述延伸部112的面上，所述导轨62为设置于所述延伸部112的正对所述滑动座12的面上。
进一步地，请参照图17及图18，导轨62的相对两端包括第一限位件63和第二限位件64。第一限位件63远离主体部111的端部。在滑动座12抵接至第一限位件63时，滑动座12移动至离壳体1最远的位置。此时，第一限位件63起到限制滑动座12移动的最大距离的作用，此时，位于滑动座12上的天线体与电子装置100的位于壳体1的本体11对应位置上的元器件的距离最远，天线模组3的辐射效率最佳。在滑动座12抵接至第二限位件64时，滑动座12收容于收容空间113中，此时电子装置100的结构规则，提高了电子装置100的便携性。
如图17及图18所示，所述壳体1的本体11内还设有地极19。所述导轨62可以为金属材质。导轨62可以电连接所述地极19。所述第一天线组件301通过电连接所述导轨62以接地。导轨62实现滑动座2的滑动功能的同时，也起到电连接地极19的功能，无需额外增加电子装置100的结构复杂性。
在一种实施方式中，滑动座12可以通过手动推动的方式靠近或远离壳体1的本体11，例如用户手动推动滑动座12靠近或远离壳体1的本体11。其他实施方式中，滑动座12也可以以电动方式靠近或远离壳体1的本体11。具体的，请返回参照图15，驱动件18连接滑动座12，驱动件18用于驱动滑动座12靠近或远离壳体1的本体11，其中，驱动件18可以为微型电机等。进一步的，所述电子装置100还包括安装于主电路板2上的控制芯片205，所述驱动件18电连接至所述主电路板2上的控制芯片205，所述控制芯片205用于响应用户对物理按键的特定操作或通过在显示模组4上进行的触摸输入操作控制驱动件18工作，从而控制滑动座12靠近或远离壳体1的本体11。滑动座12电动滑动的方式提高了电子装置100的自动化效果及智能化，提高用户体验。
例如，物理按键可包括电源按键、上音量按键和下音量按键等，控制芯片205可响应对电源按键的双击或者响应对上音量按键和下音量按键的同时按压而改变驱动件18的驱动方向，而驱动滑动座12靠近或远离壳体1的本体11滑动。又例如，控制芯片205还可响应在显示模组4上输入的特定的触摸手势，例如，用户在显示模组4上的快速上下滑动的触摸手势而改变驱动件18的驱动方向，从而驱动滑动座12靠近或远离壳体1的本体11滑动。在一些实施例中，所述触摸输入操作还可以为开启拍照应 用程序、通话应用程序、关闭拍照应用程序、通话应用程序等，当控制芯片205确定当前的触摸输入操作为开启拍照应用程序或通话应用程序等的操作时，确定用户需要使用照相机或需要提高天线性能，而控制驱动件18驱动所述滑动座12滑出本体11，当控制芯片205确定当前的触摸输入操作为关闭拍照应用程序或通话应用程序等的操作时，则控制驱动件18驱动所述滑动座12收容于本体11。
从而，当用户需要弹出滑动座12而提高天线辐射性能或使用相应的功能器件126时，可对特定的物理按键执行特定的操作或者输入特定的触摸操作即可触发滑动座12进行自动滑动。
其中，如图17或18所示，所述滑动座2与壳体1的本体11之间还设有密封件103。密封件103设于边框122和壳体1之间，以提高壳体1与滑动座2之间的密封防水性能。密封件103可以为绝缘材质，例如陶瓷或塑胶或树脂或橡胶等。在壳体1的本体以及所述滑动座12为金属材质时，密封件103用以绝缘材料。该密封件103使得壳体1的与滑动座12相绝缘，而增加与滑动座12上的天线体T1的隔离度。进一步地，该密封件103的材质可以为弹性材料。在滑动座12靠近壳体1时，滑动座12会抵接至密封件103，并将密封件103夹持滑动座12与壳体1的本体11之间，以使滑动座12与本体11之间密封。由于密封件103的弹性形变，可以避免滑动座12和本体11受到的硬性碰撞，从而减少滑动座12与本体11的损伤。
请返回一并参阅图9和图10，在一些实施例中，所述延伸部112为去除了本体11的第一面F1和第二面F2所在的壳体部分的空心框状结构。在一些实施例中，如图9所示，所述延伸部112的内壁N2还可延伸有一遮挡板B1，所述遮挡板B1用于在滑动座12滑出时，对电子装置100的内部结构进行遮挡，避免直接将内部结构裸露在外。其中，所述遮挡板B1的材质可与本体11的主体部111的材质相同，以保证外观的整体性。
在一些实施例中，所述传导线L1为从遮挡板B1的位置穿过而电连接于滑动座12上的天线体T1和射频收发电路3之间。
其中，所述电子装置100可为显示器、电视机、手机、平板电脑等电子产品。
需要注意的是，本申请的某一实施例可能仅重点介绍到一个或少数部件的变动，其他未介绍或未重点介绍的部分在其他实施例中有不同的变形方式时，在该实施例中也适用。
显然，所述电子装置100还可包括其他的元件，例如存储器等等，由于与本申请改进无关，故未在此描述。
本申请提供的壳体1及电子装置100，通过将天线体T1设置于可滑动的滑动座12上，从而，可有效保证天线性能，又能够尽可能地增大屏占比。
以上是本申请实施例的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
