此处的附图被并入说明书中构成本说明书的一部分，示出了符合本申请的实施例，与说明书一起用于解释本申请的原理。
具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
在一种具体实施例中，下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
如图1和图2所示，本申请实施例提供了一种终端，其包括键盘装置01和平板设备02，平板设备02与键盘装置01相配合，成为类似笔记本电脑的终端设备，其可配合键盘或手写笔等使用，实现word、PS等办公软件的应用，达到提升生产力的目的，增加终端产品的卖点和可玩性的目的。平板设备02通过可拆卸的方式固定于键盘装置01，例如平板设备02的可以通过磁铁或卡接等固定方式固定在键盘装置01内，且平板设备02能够与键盘装置01通讯连接，从而可以通过键盘装置01控制平板设备02。当键盘装置01关闭时，平板设备容纳于键盘装置01围成的空间内，通过键盘装置01对平板设备02起到保护作用；当键盘装置01撑开时(即键盘装置01处于支撑状态时)，平板设备02承载于键盘装置01上，通过键盘装置01对平板设备02起到支撑作用，使平板设备02能够保持在倾斜状态，从而形成合适的展示角度。
通常情况下，键盘装置01包括底座1、第一板3和第二板4。底座1形成键盘装置01的主要支撑部分，底座1上可以承载键盘模组2；第一板3转动连接于底座1的一端，与底座之间形成第一转动部位；第二板4转动连接于第一板3远离底座1的一端，与第一板之间形成第二转动部位，第二板4上可以承载平板设备02。当第二板4向靠近于底座1的方向翻转，直至第二板4与第一板3均与底座1的表面相平行时，键盘装置01关闭，平板设备02容纳于第二板4、第一板3与底座1围成的区域内；当第二板4向远离底座1的方向翻转时，键盘装置01撑开，平板设备02的底端支撑于键盘模组2，从而在底座1、第一板3和平板设备02之间形成三角支撑结构，使平板设备02保持在倾斜状态。采用这种结构，当需要撑开键盘装置01时，使用者需要 先翻转第二板4提起平板设备02，再将平板设备02的底端支撑于键盘模组2，用户使用时操作比较复杂，且平板设备的支撑角度少，难以实现支撑角度的连续调节，从而影响终端设备的使用体验。
由此，本申请实施例提供的键盘装置01还包括第三板5。键盘模组2滑动连接于底座1，键盘模组2能够沿底座1的前后方向滑动，即键盘模组2能够向内(远离使用者的方向)滑动而形成收纳状态，键盘模组2能够向外(靠近使用者的方向)滑动而形成使用状态；第三板5转动连接于键盘模组2靠近第一板3的一端，固定于第二板4，以带动第二板4转动，第三板5用于承载平板设备02，第三板与键盘模组之间形成第三转动部位；第三板5可以设置于第二板4的延长线上，也可以覆盖于第二板4的表面，第三板5可以与第二板4一体成型，也可以通过粘接或螺纹连接等方式进行连接，只要能够使第三板5固定于第二板4即可。通过第三板5在第二板4与键盘模组2之间起到连接作用，形成连杆滑块机构，实现键盘装置01和平板设备02的联动；当使用者翻转平板设备02时，第三板5随着平板设备02一起转动，第三板5通过第二板4带动第一板3转动，第三板5的底端带动键盘模组2沿底座1前后滑动，从而使底座1、第一板3以及第三板5形成三角支撑结构。
具体来说，当需要使用终端设备时，第三板5随着平板设备02一起向远离底座1的方向翻转，键盘模组2随着第三板5的角度变化而向外滑动；当关闭终端设备时，第三板5随着平板设备02一起向靠近底座1的方向翻转，键盘模组2随着第三板5的角度变化而向内滑动。也就是说，使用时只需要操作平板设备02翻转，即可将键盘装置01切换到关闭状态或支撑状态，简化了操作过程，使终端设备具有科技感和高级感，提高了终端设备的使用体验。
进一步地，键盘装置01的转动部位可以设置阻尼结构，阻尼结构可以包括第一阻尼结构24和第二阻尼结构25，第一阻尼结构24和第二阻尼结构25分别设置于转动部位的两端，第一阻尼结构24与第二阻尼结构25可以采用相同的结构形式，也可以采用不同的结构形式。通过阻尼结构形成运动阻力，使底座1、第一板3与第三板5能够形成稳定的三角支撑结构，从而使第三板5能够在相对于底座1倾斜的任意角度位置保持悬停状态，实现预设角度范围内(即平板设备02与底座1之间的夹角的范围，例如90°～130°)任意角度的稳定悬停，实现无级角度的展示效果，满足用户最大数量场景下的角度变化需求。
此外，由于本申请实施例通过键盘模组2前后滑动改变平板设备02底端的支撑位置，从而改变平板设备02的倾斜角度，无需在键盘模组2上预留调节空间，从而提高了键盘模组2的有效利用率，方便在键盘模组2上设置触摸板210(touchpad)的功能区域，本申请实施例中触摸板210设置于键盘本体21靠近使用者的区域。
进一步地，键盘模组2的底部还包括键盘补强板29，以增加键盘模组2的支撑强度，防止键盘模组2产生损坏或变形，延长键盘模组2的使用寿命，键盘补强板29固定连接于键盘模组2的底部，且键盘补强板29滑动连接于底座1，从而实现键盘模组2与底座1之间的滑动连接。
进一步地，当键盘装置01上还可以设置Type-C模块235，通过Type-C模块235可以对平板设备02充电，无需通过平板设备02自身的充电接口充电，可以防止使用 者携带终端设备移动过程中，充电线与平板设备02之间产生拉扯，导致平板设备02自键盘装置01上滑落，影响使用安全。
具体地，如图3-图5所示，本申请实施例提供的键盘装置的开启操作过程可参考如下：键盘装置01处于关闭状态时，第三板5与底座1相平行，且第三板5与底座1之间形成容纳平板设备02的空间(参考图3)；当需要使用平板设备02时，使用者对第三板5施力，使第三板5向远离底座1的方向转动，第三板5与底座1之间逐渐形成不大于90°的夹角，第一板3随着第二板4一起向远离底座1的方向转动，第三板5对键盘模组2施力使键盘模组2向外滑动(参考图4)；当键盘装置01撑开时，第三板5与底座1之间形成90°～130°的夹角，底座1、第一板3与第三板5形成稳定的三角支撑结构(参考图5)。
其中，键盘装置的各转动部位可以采用贴皮、铰链或转轴等连接方式。贴皮连接形式包括柔性片材，通过柔性片材的折弯变形，实现相邻两个部件之间的相对转动，结构简单，且能够改善装置的外观性；转轴连接形式可以包括相互转动配合的固定座和转轴，即固定座上设置轴孔，转轴安装于轴孔内与轴孔转动配合，通过转轴连接形成稳定的转动配合连接，且转轴连接处易于布置阻尼结构。
在一些实施例中，参考图6，底座1与第一板3之间通过转轴连接，第一板3与第二板4之间采用贴皮连接，第三板5与键盘模组2之间采用贴皮连接。底座1包括相互转动配合的固定座22和转轴，固定座22设置于底座1的一端，转轴与第一板3固定连接，以增加第一板3动作的稳定性，从而增加支撑的可靠性；固定座22和转轴之间设有阻尼结构，在转动行程内，第一板3能够稳定保持在任意位置，使得底座1、第一板3与第三板5之间形成的三角支撑结构的形状保持稳定不变，也就是说，平板设备02能够保持在任意角度的倾斜状态；第一板3与第二板4之间以及第三板5与键盘模组2之间分别通过柔性片材6相连接，以减小连接尺寸，从而形成平整的外观。
进一步地，第三板5的底部可以设置弧形支撑部51，用于支撑平板设备02；弧形支撑部51上可以设置Pogopin模组，Pogopin模组分别与键盘模组2电连接和Type-C模块电连接，从而实现平板设备02与键盘装置01的通讯连接，实现对平板设备02的充电功能。
在另一些实施例中，参考图7，键盘模组2与第三板5之间采用转轴连接，第一板3与第二板4之间采用贴皮连接，第一板3与底座1之间采用贴皮连接。键盘模组2包括相互转动配合的固定座22和转轴23，固定座22设置于键盘模组2的一端，转轴23与第三板5固定连接，以增加第三板5动作的稳定性和连接强度，防止第三板5晃动影响平板设备02的稳定性，有效避免第三板5与键盘模组2之间的连接破损；固定座22与转轴23之间设有阻尼结构，在转动行程内，第三板5能够稳定保持在任意位置，使得平板设备02能够保持在任意角度的倾斜状态。第一板3与第二板4之间以及第一板3与底座1之间分别通过柔性片材6相连接，以形成连续平整的外观。
如图8-图10所示，在一种实施例中，转轴23设置成中空结构，转轴23的中部设置开口，开口连通转轴23的内部空腔，开口处安装有盖板234；转轴23的内部空腔内可以设置Pogopin模组236，Pogopin模组236分别与键盘模组2电连接和Type-C模块235电连接，从而实现平板设备02与键盘装置01的通讯连接，实现对平板设备 02的充电功能。Pogopin模组236可以自开口处装入转轴23内，通过盖板234进行遮挡和防护。Pogopin模组236的探针伸出转轴23，当平板设备02连接于键盘装置01时，Pogopin模组236的探针与平板设备02的相关接口相配合，从而实现平板设备02与键盘装置01之间的电连接。
具体来说，Pogopin模组236的探针在平板设备02所在的一侧突出于转轴23，Pogopin模组236随着转轴23一起转动，从而使平板设备02在任意角度开启时，均能够与键盘装置01保持电连接状态；当键盘装置01关闭时，Pogopin模组236的探针随着转轴23转动至靠近底座1的位置(参见图9)；当键盘装置01撑开时，Pogopin模组236的探针随着转轴23转动至远离底座1的位置(参见图10)。
进一步地，转轴23内还可以设置磁铁模组231，平板设备02通过磁性吸附连接于转轴23，增加平板设备02与键盘装置01之间电连接的可靠性。当然，平板设备02与转轴23之间也可以通过定位柱或限位槽等方式进行连接。
如图11-图14所示，在另一种实施例中，转轴23设置成中空结构，转轴23的中部设置开口，开口连通转轴23的内部空腔，开口处安装有盖板234并转动连接有活动部232，活动部232能够绕转轴23转动。第三板5固定连接于活动部232，随着活动部232一起运动。Pogopin模组236固定连接于活动部232，随活动部232一起装入转轴23内。Pogopin模组236的探针伸出活动部232而电连接于平板设备02。
其中，活动部232与转轴23之间可以设置第三阻尼结构26，且活动部232与转轴23之间的阻尼大于活动部232与固定座22之间的阻尼，当第三板5翻转时，活动部232首先与转轴23一起绕固定座22转动，当转轴23转动至最大角度之后，转轴23停止转动，活动部232绕转轴23转动，进一步调整平板设备02的角度。具体来说，当键盘装置01关闭时，转轴23和活动部232均转动至最靠近底座1的位置(参见图12)；当需要撑开键盘装置01时，转轴23向远离底座1的方向转动，由于活动部232与转轴23之间存在较大阻尼，活动部232与转轴23保持相对静止；直至转轴23转动至最大角度(例如90°，该角度值可以根据需要进行合理设计)时，转轴23停止转动，活动部232开始转动(参见图13)；当活动部232转动至最大角度时，当键盘装置01完全撑开时，使平板设备02实现最大130°的开启角度(参见图14)。
如图8、图11、图15和图16所示，本申请实施例提供的第一阻尼结构24包括相互压紧的第一凸轮241和第二凸轮242，第一凸轮241固定连接于固定座22，第二凸轮242固定连接于转轴23。第一凸轮241的端面上设置有凸起结构，通过该凸起结构顶抵于第二凸轮242的端面上，从而形成阻尼；通过合理设计第二凸轮242的端面结构，可以实现预定的阻尼大小，从而实现预定角度范围内任意角度稳定悬停，实现无级角度的展示效果。
进一步地，第一阻尼结构24还包括第一支撑轴243，第一支撑轴243固定连接于转轴23的一端，例如第一支撑轴243与转轴23之间通过第一花键243b等任意能够传递扭矩的结构相连接，第一凸轮241通过第一支撑轴243连接于转轴23，从而使第一阻尼结构24能够独立于固定座22和转轴23，形成能够单独生产制造的模块，提高第一阻尼结构24使用的便利性。其中，第二凸轮242滑动连接于第一支撑轴243，例如，第二凸轮242与第一支撑轴243之间设置相互配合的非圆形结构，使第二凸轮242能 够随着第一支撑轴243一起转动；第一凸轮241套设于第一支撑轴243，使第一凸轮241能够相对于第一支撑轴243转动，从而使第一凸轮241与第二凸轮242相对转动；第一凸轮241背离第二凸轮242的一侧可以设置第一限位台肩243a，以限定第一凸轮241的位置，使第一凸轮241与第二凸轮242之间形成压紧力。
进一步地，第一阻尼结构24还包括第一弹性件244，第一弹性件244包括多个依次叠放的碟簧，第一弹性件244设置于第二凸轮242背离第一凸轮241的一侧，第一弹性件244的两端分别弹性顶抵于第一支撑轴243与第二凸轮242，以迫使第二凸轮242压紧第一凸轮241。可以理解地，第一弹性件244也可以采用其他能够提供压紧力的结构件，例如弹簧等。
进一步地，第一阻尼结构24还包括第一调节螺母245，第一弹性件244的两端分别弹性顶抵于第一调节螺母245与第二凸轮242，通过第一调节螺母245调节第一弹性件244的预紧力，从而调节第一阻尼结构24的阻尼大小。
进一步地，第一阻尼结构24还包括第一缓冲垫片246，第一缓冲垫片246设置于第一调节螺母245与第一弹性件244之间，通过第一缓冲垫片246起到缓冲和放松的作用，从而确保第一调节螺母245与第一弹性件之间形成平面接触。
如图8、图11、图17和图18所示，本申请实施例提供的第二阻尼结构25包括单向轴承251和摩擦片252，单向轴承251的外圈固定连接于固定座22，摩擦片252连接于转轴23，从而在摩擦片252与单向轴承251的内圈之间形成阻尼。
当转轴23向远离底座1的方向转动时，单向轴承251的内圈可以自由转动，转轴23通过摩擦片252带动单向轴承251的内圈转动，从而撑开键盘装置01；当转轴23向靠近底座1的方向转动时，单向轴承251的内圈与外圈相固定而无法转动，转轴23带动摩擦片252转动，摩擦片252与单向轴承251的内圈之间产生相对转动形成阻尼。也就是说，本实施例提供的第二阻尼结构25能够使键盘装置实现“开轻关重”的特性，避免由于关闭过快导致的意外发生，提高终端设备的使用性能；当使用者撑开键盘装置01时，第二阻尼结构25不产生阻尼，从而允许使用者以较小的力撑开键盘装置01，使操作更加省力和流畅；当使用者关闭键盘装置01时，第二阻尼结构25产生阻尼，避免键盘装置01关闭时下滑速度过快，导致夹伤使用者，或者导致平板设备02与底座1碰撞而损坏。
进一步地，第二阻尼结构25还包括第二支撑轴253，第二支撑轴253固定连接于转轴23的一端，例如第二支撑轴253与转轴23之间通过第二花键253b等任意能够传递扭矩的结构相连接，摩擦片252通过第二支撑轴253连接于转轴23，从而使第二阻尼结构25能够独立于固定座22和转轴23，形成能够单独生产制造的模块，提高第二阻尼结构25使用的便利性。其中，摩擦片252滑动连接于第二支撑轴253，例如，摩擦片252与第二支撑轴253之间设置相互配合的非圆形结构，使摩擦片252能够随着第二支撑轴253一起转动；单向轴承251套设于第二支撑轴253，使单向轴承251的内圈能够相对于第二支撑轴253转动，也就是说，第二支撑轴253不直接带动单向轴承251的内圈转动，而是通过摩擦片252带动单向轴承251的内圈转动；单向轴承251背离摩擦片252的一侧可以设置第二限位台肩253a，以限定单向轴承251的位置，使单向轴承251的内圈与摩擦片252之间形成压紧力。
进一步地，第二阻尼结构25还包括第二弹性件254，第二弹性件254包括多个依次叠放的碟簧，第二弹性件254设置于摩擦片252背离单向轴承251的一侧，第二弹性件254的两端分别弹性顶抵于第二支撑轴253与摩擦片252。可以理解地，第二弹性件254也可以采用其他能够提供压紧力的结构件，例如弹簧等。
进一步地，第二阻尼结构25还包括连接件255，连接件255的第一端固定连接于单向轴承251的内圈，摩擦片252压紧连接件255的第二端，也就是说，连接件255在单向轴承251与摩擦片252之间起到连接作用，在摩擦片252与连接件255的第二端之间产生阻尼；连接件255的第一端横截面较小，以便于连接单向轴承251；连接件255的第二端横截面较大，以便与摩擦片252形成较大的接触面积，从而形成平稳可靠的连接。
进一步地，第二阻尼结构25还包括摩擦垫片256，摩擦垫片256滑动连接于连接件255的第二端，摩擦垫片256与连接件255沿周向相对固定(即二者无法相对转动)，摩擦片252压紧摩擦垫片256，即利用摩擦原理在摩擦片252与摩擦垫片256之间产生阻尼。
进一步地，第二阻尼结构25还包括第二调节螺母257，第二弹性件254的两端分别弹性顶抵于第二调节螺母257与摩擦片252，通过第二调节螺母257调节第二弹性件254的预紧力，从而调节第二阻尼结构25的阻尼大小。
进一步地，第二阻尼结构25还包括第二缓冲垫片258，第二缓冲垫片258设置于第二调节螺母257与第二弹性件254之间，通过第二缓冲垫片258起到缓冲和放松的作用，从而确保第二调节螺母257与第二弹性件254之间形成平面接触。
如图19所示，上述底座1上设有第一导轨11和第二导轨12，第一导轨11设置于底座1的中央，第二导轨12对称分布于第一导轨11的两侧；键盘模组2的中央滑动连接于第一导轨11，键盘模组2的两侧分别滑动连接于第二导轨12，从而使键盘模组2与底座1之间能够稳定顺畅的滑动。此外，第一导轨11对键盘模组2的中央位置起到支撑作用，防止键盘模组2的中央下沉导致键盘模组2发生弯曲；通过第二导轨12对键盘模组2的两侧起到连接作用，防止键盘模组2的两侧上翘导致键盘模组2发生弯曲。
进一步地，第一导轨11设置于底座1靠近第一板3的一端(即底座1的前端)，向远离第一板3的方向延伸至底座1的中部；第二导轨12设置于底座1远离第一板3的一端(即底座1的后端)，向靠近第一板3的方向延伸至底座1的中部；使第一导轨11和第二导轨12形成三角形的分布结构，从而对键盘模组2形成稳定的平面支撑结构；而且，由于第二导轨12靠近底座1的后端，能够防止键盘模组2滑动过程中第二导轨12裸露，导致第二导轨12处划伤或夹伤使用者。此外，第二导轨12靠近底座1的后端，还能够使第二导轨12对键盘模组2的作用位置尽可能靠近键盘模组2的后端；当键盘装置01关闭时，键盘模组2滑入底座1，第二导轨12对键盘模组2的连接点靠近键盘模组2的后端，可以有效防止键盘模组2的后端上翘导致键盘模组2发生弯曲；当键盘装置01撑开时，键盘模组2滑出底座1，第二导轨12对键盘模组2的支撑点靠近键盘模组2的后端，从而可以减小键盘模组2滑出后对第二导轨12产生的力矩，防止键盘模组2底部向上翘起。
如图20所示，本申请实施例提供的第一导轨11包括连接座114和两个第一滑槽113，两个第一滑槽113均设置于连接座114上，两个第一滑槽113相对设置，沿底座1的前后方向延伸；键盘模组2的中央设有与第一导轨11相配合的第一滑块27，第一滑块27的两侧分别插入两个第一滑槽113，且第一滑块27能够沿第一滑槽113滑动；第一滑块27与第一滑槽113之间可以设置POM胶，起到自润滑作用，保证滑轨运动长期可靠性。
进一步地，第一导轨11的上设有第一止挡部111，第一止挡部111设置于两个第一滑槽113之间，即第一止挡部111设置于连接座114上，当第一滑块27沿第一滑槽113滑动时，第一滑块27能够止挡于第一止挡部111，以限定键盘模组2的滑动行程，从而限定平板设备02翻转的最大角度。
进一步地，第一导轨11靠近第一板3的一端设有第二止挡部112，第二止挡部112设置于两个第一滑槽113之间，即第二止挡部112设置于连接座114上，当第一滑块27沿第一滑槽113滑动时，第一滑块27能够止挡于第二止挡部112，以防止键盘模组2反向滑出底座1。通过第二止挡部112起到防呆作用，防止使用者在键盘装置01的正反面颠倒时撑开键盘装置01，导致键盘装置01损坏，也就是说，当使用者将键盘装置01的正反面颠倒(即第一板3和第二板4朝下，底座1朝上)撑开键盘装置01时，使用者翻转底座1，由于第一板3与第二板4之间无法相对转动，导致键盘模组2会有向前方滑动的趋势，通过设置第二止挡部112可以阻止键盘模组2向前滑动，从而防止键盘模组2反向滑出底座1，确保使用安全。
如图21所示，第二导轨12包括第二滑槽121，第二滑槽121沿底座1的前后方向延伸，且第二滑槽121的开口方向朝向底座1的中央，两个第二导轨12以底座1的中央为中心呈左右对称分布；键盘模组2的两侧分别设有第二滑块28，第二滑块28的一侧固定连接于键盘模组2，另一侧插入第二滑槽121，能够沿第二滑槽121滑动；第二滑块28与第二滑槽121之间可以设置POM胶，起到自润滑作用，保证滑轨运动长期可靠性。
具体地，上述第一导轨11和第二导轨12可以通过冲压工艺形成适当的形状，工艺简单；第一导轨11和第二导轨12通过激光焊接或胶水粘接方式，固定连接于镶埋在底座1里的铁件固定在一起；第一滑块27和第二滑块28通过螺钉等紧固件，固定连接于镶埋在键盘模组2里的铁件。
