具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
下面，将参考附图详细地说明本公开实施例提供的插头、接口设备及其识别方法。
图1为本公开至少一实施例提供的插头的俯视结构示意图。图2为图1中插头的侧面结构示意图。图3为图2中插头的导电针伸出后的结构示意图。结合图1、图2和图3，本实施例提供的插头例如可以配置在接口设备上，用于插接到外设接口，例如外设的数据接口。该插头包括至少一个由多个绝缘针10组成的绝缘针排，绝缘针10沿轴向可伸缩，绝缘针排的中心线的至少一侧设置有沿轴向可伸缩的导电针20，导电针20设置在相邻的两个绝缘针10之间。
例如，导电针20为多个，每相邻的两个绝缘针10之间设置有一个导电针20，例如，导电针20的外表面分别与与其相邻的绝缘针10的外表面相抵接。
本实施例提供的插头，通过将插头的导电针20设置为沿轴向可伸缩，从而，在人眼无法辨别的环境如黑暗环境下，当将插头插入不明接口标准的数据接口中时，在电触点位置，导电针伸出与电触点电连接，在非电触点位置，导电针受压缩回，在一些示例中，每相邻的两个绝缘针10之间设置有一个导电针20，使得数据接口上的每个电触点都可以与对应的导电针电连接，避免遗漏电触点，通过将导电针20的外表面分别与相邻的绝缘针10的外表面相抵接，使得绝缘针10可以从侧向向导电针20施加一定的作用力，使得导电针与电触点充分接触，避免了导电针与电触点虚接，实现了在人眼无法辨别的环境如黑暗环境下，插头与不明接口标准的数据接口的正确电接 触。
例如，在图3中示出，导电针20伸出后，导电针20的顶端与绝缘针10的顶端平齐，然而可以理解的是，导电针20伸出后，导电针20的顶端也可以高于或低于绝缘针10的顶端，只要导电针20伸出后可与数据接口的电触点接触即可。
通常，电子设备如手机上常用的数据接口的接口标准采用USB、闪电接口标准等，虽然这些数据接口的电触点之间的间距相等，但由于采用的接口标准不同，所以对应的每个电触点的定义不同，因此，在与这些电子设备充电或通信时，需要仔细分辨数据接口对应的接口标准，以选择适用的插头。
本实施例提供的插头可以覆盖对应数据接口的常用接口标准。例如，本实施例提供的插头中，相邻导电针的间距与对应数据接口的相邻电触点的间距相等，绝缘针根据导电针的位置和结构设置，从而，本实施例提供的插头可以应用在对应数据接口的常用接口标准中，只要电子设备具有对应的数据接口，本实施例提供的插头均可以与该数据接口插接，使得插头的导电针与数据接口的电触点正确接触。例如，当一个手机的数据接口采用USB接口标准时，由于USB接口标准属于与插头对应的数据接口的接口标准，所以本实施例提供的插头可以插入该手机的数据接口中。例如，当一个手机的数据接口采用闪电接口标准时，由于闪电接口标准属于与插头对应的数据接口的接口标准，所以本实施例提供的插头可以插入该手机的数据接口中，实现对应的导电针与手机数据接口的电触点接触。
可以理解的是，接口设备的插头通常是带电的，为了保证插头的使用安全，例如，插头还包括设置在与插头插接端相对一侧的壳体100，导电针20和绝缘针10的底端(即插接端的相对端)均设置在壳体100内。可以理解的是，导电针和绝缘针的插接端也就是插入数据接口的一端，在图3中示出为顶端，插接端的相对端在图3中示出为底端，从图3中可以看出，导电针20和绝缘针10的底端均设置在壳体100内。当插头未插入数据接口时，导电针20沿轴向收缩在壳体100内，如图2所示，当插头插入数据接口时，导电针20沿轴向伸出与对应电触点接触，如图3所示。
本实施例提供的插头，当插头未插接到数据接口时，导电针20沿轴向收缩在壳体100内，不会给使用者带来触电危险，保证了插头的使用安全，而且还可以避免外力对导电针20的损伤，从而对导电针20起到保护作用。
例如，在本实施例中，如图1所示，相邻的绝缘针10的外表面相抵接，绝缘针10的截面外径大于导电针20的截面外径。从而保证了绝缘针10和导电针20在伸缩过程中可以准确定位，避免多次使用后导电针20出现偏移无法与数据接口的电触点良好接触。
例如，如图1所示，导电针20的截面形状呈圆形，绝缘针10的截面形状也呈圆形，可以理解的是，在其它实施例中，导电针20的截面形状还可以呈多边形等其他形状，绝缘针10的截面形状也可以呈多边形等其他形状，只要能满足需求即可。
例如，图4为图1中导电针的轴向截面结构示意图。例如，如图4所示，插头还包括设置在壳体内的第一固定座30，第一固定座30具有第一容纳腔31，导电针20包括位于顶部的针部22和位于底部的台阶柱21，台阶柱21位于第一容纳腔31内。例如，插头还包括位于第一容纳腔31的底壁与台阶柱21之间的可压缩第一弹性元件40。
例如，现在的日常生活中，常用的电子设备为手机，图5为一种手机常用的数据接口。图5中的数据接口覆盖了手机常用数据接口的接口标准，在图5中，数据接口的上电触点和下电触点之间通常为凹陷区域，可以理解的是，实际生活中，手机的数据接口不一定具有16个电触点，通常数据接口根据接口标准具有图5中的某些电触点。因此，为了方便对手机进行充电或通信，如图1所示，本实施例中的接口设备，包括一个绝缘针排，绝缘针排中心线的上下两侧均设置有导电针20，从而覆盖了现有手机的接口标准。
例如，在本实施例中，当插头插入图5所示的数据接口中时，所有绝缘针10均位于数据接口的凹陷区域，也就是说，没有绝缘针10被压缩。由于导电针20收缩在壳体100内，为了使得导电针20伸出，例如，插头还包括卡接件，台阶柱21的外表面上设置有与卡接件相卡接的卡合部，卡接件是可控的，使得卡接件能够在与卡合部卡接以及脱离卡合部之间切换。
例如，在一个示例中，如图4所示，卡接件为沿导电针径向可拨动的拨钮50，台阶柱21的外表面上设置有与拨钮50相卡接的凹槽，在拨钮50和第一弹性元件40的配合下，可以手动控制导电针伸出或缩回。例如，当插头插入数据接口后，手动拨动拨钮50使得导电针伸出与数据接口的电触点接触。当插头离开数据接口后，手动拨动拨钮50使得导电针缩回。为了说明，图4中示出了一个导电针，同时示出了拨钮50，可以理解的是，在一些 示例中，各个导电针的拨钮可以是一个整体结构，从而在拨动拨钮时，所有的导电针均可以伸出或缩回。
可以理解的是，在一些示例中，可以合理设置拨钮的保持力，从而，当拨动拨钮使导电针伸出时，在与电触点对应的位置的导电针可以伸出与电触点接触，在没有电触点的位置，导电针受到的外力大于拨钮保持力，以避免导电针伸出。
本实施例中，卡接件与卡合件可以为任意形式，只要其可以控制导电针的伸出和缩回即可。例如，在其他示例中，卡接件可以为沿导电针径向可伸出的卡头，台阶柱的外表面上具有与卡头相配合的卡套，卡头可以伸入到卡套中以实现卡接。由此，在卡头和第一弹性元件的配合下，可手动控制导电针伸出或缩回。
例如，在本实施例中，所有绝缘针均与数据接口的凹陷区域相对应，所以，本实施例中的绝缘针可以沿轴向伸缩，同样，也可以不沿轴向收缩而是保持位置固定。
例如，图6a为本实施例提供的插头找到数据接口位置时的示意图，图6b为继图6a后导电针伸出与电触点接触的示意图。结合图6a和图6b，本实施例提供的插头与图5所示数据接口的连接过程如下：在黑暗环境下，通过触摸大概确认手机的数据接口位置，将插头朝向数据接口位置插入，由于数据接口的上电触点和下电触点之间为凹陷区域，因此，绝缘针全部插入到数据接口的凹陷区域，如图6a所示，手动拨动拨钮使得导电针伸出与电触点接触，如图6b所示，由此实现插头与数据接口的连接。
图7为本公开至少一实施例提供的另一插头的俯视结构示意图。图8为图7中插头的侧面结构示意图。图9为图8中插头的导电针伸出后的结构示意图。参考图7、图8和图9，本实施例的插头与上述实施例不同的是，在本实施例中，插头在对应外设接口，例如外设的数据接口外围的部位也设置有至少一个绝缘针10(即外部绝缘针)，至少一个外部绝缘针10和导电针20通过联动机构连接，联动机构设置在壳体100内，当插头未插入数据接口时，导电针20处于轴向收缩状态，沿轴向收缩在壳体100内，如图8所示，当至少一个绝缘针10的顶端受压收缩时，在联动机构的作用下，导电针20从壳体100伸出，如图9所示。
本实施例提供的插头，当插头插入数据接口时，由于数据接口的外围为 电子设备的外表面，所以位于数据接口外围的绝缘针10会被电子设备的外表面压缩，在联动机构的作用下，导电针20从壳体100内自动伸出与数据接口的电触点接触。
例如，图10示出了插头插入数据接口时联动机构的状态示意图。例如，如图10所示，插头还包括第一固定座30和第二固定座90，导电针设置在第一固定座30上，绝缘针10设置在第二固定座90上。第一固定座30具有第一容纳腔31，第一容纳腔31的底端具有开口，导电针20包括位于顶部的针部22和位于底部的台阶柱21，台阶柱21位于第一容纳腔31内，针部22伸出第一固定座30外。第二固定座90具有第二容纳腔91，绝缘针20的底部设置在第二容纳腔91内，绝缘针20的顶端设置在第二固定座90之外。
例如，联动机构包括设置在台阶柱21的下方且可在第一容纳腔31内滑动的第一活塞32，联动机构还包括可压缩的第二弹性元件60和可压缩的第三弹性元件70，第二弹性元件60位于台阶柱21与第一容纳腔31的内顶壁之间，第三弹性元件70位于台阶柱21与第一活塞32之间。例如，联动机构还包括设置在绝缘针10下方且可在第二容纳腔91内滑动的第二活塞92以及设置在第二活塞92和绝缘针10之间的可压缩的第四弹性元件95。例如，联动机构还包括连动杆80以及设置在连动杆80上的转轴81，连动杆80围绕转轴81可转动，连动杆80的两端分别抵接在第一活塞32上和第二活塞92上。例如，第二弹性元件、第三弹性元件和第四弹性元件可以为弹簧等弹性元件。
结合图10，联动机构的工作原理如下：当插头插入数据接口时，位于数据接口外围的绝缘针10受到外力向下移动，绝缘针10的底端作用在第四弹性元件95上，第四弹性元件95压缩推动第二活塞92向下移动进而推动连动杆80的右端，使得连动杆80顺时针围绕转轴81转动，使得连动杆80的左端向上推动活塞32，在活塞32的推动下，导电针20向上移动伸出并与数据接口的电触点接触，由此实现插头与数据接口的连接。当插头离开数据接口时，在第二弹性元件60和第三弹性元件70的作用下，连动杆80逆时针旋转复位，导电针20缩回壳体内，绝缘针10向上移动复位，由此插头脱离数据接口。
例如，图11为本公开至少一实施例提供的再一种插头的俯视结构示意图。如图11所示，本实施例提供的插头与上述实施例不同的是，在本实施 例中，插头包括多个绝缘针排，每相邻的两个绝缘针排之间均设置有导电针20，也就是说，导电针20设置在绝缘针10之间的缝隙中，从而，绝缘针可以更好地稳固导电针的位置。
本实施例提供的插头，无论数据接口电触头的阵列数量如何，插头均可以插入对应的外设接口，例如外设的数据接口内，绝缘针和导电针均可以根据对应的位置伸出或缩回，由此可以扩大接头的应用范围，而且在多次使用后，导电针不会出现位置偏移，从而可以提高插头的电气性能。
本公开至少一实施例提供了一种接口设备，该接口设备包括上述实施例提供的插头。例如，该接口设备还包括识别电路和识别模块，导电针可电连接到识别电路，识别模块用于识别外设接口，例如外设的数据接口的接口标准，以使得接口设备与电子设备进行通信连接。
例如，图12为本公开至少一实施例提供的一种识别电路与导电针连接的示意图。该接口设备还包括识别电路300和识别模块，每个导电针均电连接到识别电路，识别模块用于通过识别电路300识别数据接口的接口标准，以使得接口设备与电子设备进行通信连接。
例如，如图12所示，识别电路300包括检测触点301和多个通信触点302，插头未插入数据接口时，每个导电针均与检测触点301电连接。
例如，图13为本公开至少一实施例提供的一种识别模块的结构示意图，如图13所示，识别模块包括检测单元303、获取单元304和确定单元305和配置单元306。
例如，检测单元303用于检测插头是否连接到数据接口。例如，检测单元303根据检测触点的参数变化检测插头是否连接到外设接口。当接口设备的插头未插入数据接口时，每个检测触点具有相同的参数，当插头插入数据接口时，检测触点的参数会产生变化，检测单元可以根据该变化检测插头是否连接到数据接口。可以理解的是，检测触点的参数例如可以为电压参数、电流参数等。
例如，获取单元304用于获取检测触点的参数。
例如，确定单元305用于根据检测触点的参数确定数据接口的接口标准。具体地，根据检测触点的参数确定数据接口的接口标准包括：根据检测触点的参数确定数据接口的电触点数量；利用参数与电触点定义的对应关系，查找与检测触点的参数对应的电触点定义；根据电触点定义确定电触点顺序； 根据电触点数量、电触点定义和电触点顺序确定数据接口的接口标准。
例如，数据接口电触点分别为VCC、DATA-、DATA+、GND，那么分别与VCC、DATA-、DATA+、GND接触的导电针对应的检测触点的参数是各不相同的。例如，当导电针分别与VCC、DATA-、DATA+、GND接触时，检测触点的参数分别为V1、V2、V3、V4。如果获取单元获取到检测触点的参数分别为V1、V2、V3、V4，根据检测触点的参数确定电触点数量为4。利用参数与电触点定义的对应关系，查找到与参数V1、V2、V3、V4对应的电触点定义分别为VCC、DATA-、DATA+、GND，并确定电触点顺序为VCC、DATA-、DATA+、GND，根据电触点数量、电触点定义和电触点顺序确定数据接口的接口标准为USB。
例如，在另一个示例中，数据接口电触点除了VCC、DATA-、DATA+、GND外，还可以包括ID电触点，以用于识别不同的连接设备。例如，ID电触点在悬空或者接地的状态对应于不同的设备，因此接口设备还可通过识别ID电触点的参数识别不同的设备。例如，当导电针分别与VCC、DATA-、DATA+、GND和ID接触时，检测触点的参数分别为V1、V2、V3、V4和V5。如果获取单元获取到检测触点的参数分别为V1、V2、V3、V4和V5，根据检测触点的参数确定电触点数量为5。利用参数与电触点定义的对应关系，查找到与参数V1、V2、V3、V4和V5对应的电触点定义分别为VCC、DATA-、DATA+、GND和ID，并确定电触点顺序为VCC、DATA-、DATA+、GND和ID，根据电触点数量、电触点定义和电触点顺序确定数据接口的接口标准为对应设备的USB。
例如，配置单元306用于根据数据接口的接口标准配置导电针与识别电路中对应的通信触点电连接，以使得接口设备与电子设备进行通信。例如，当确定单元确定数据接口的接口标准为USB后，配置与电触点接触的导电针与识别电路的对应通信触点电连接，从而将接口设备与电子设备通信连接，使得接口设备与电子设备进行通信。
本实施例提供的接口设备，通过设置识别电路和识别模块，并且识别模块通过识别电路识别数据接口的接口标准，以使得接口设备与电子设备进行通信连接，实现了在人眼无法辨别的环境如黑暗环境下，接口设备与不明接口标准的数据接口的自动通信连接，可以更加便捷地识别和连接手机等电子设备，快速实现对电子设备的充电和数据连接。
本公开至少一实施例提供了一种智能音箱底座，该智能音箱底座包括上述实施例中的接口设备。

例如，该接口设备还包括识别电路，每个导电针均电连接到识别电路。例如，识别电路包括检测触点和多个通信触点，插头未插入数据接口时，每个导电针均与检测触点电连接。
例如，在一个实施例中，识别方法包括：检测插头是否连接到外设接口，例如外设的数据接口，当检测到插头连接到外设接口时，将导电针与识别电路中对应的通信触点电连接。例如，根据检测触点的参数变化检测到插头是否连接到数据接口。
例如，在另一实施例中，图14为该实施例提供的一种识别方法的示意图，该识别方法包括：
S1：根据检测触点的参数变化检测插头是否连接到数据接口；当检测到插头已连接到数据接口时，识别方法还包括：
S2：获取检测触点的参数；
S3：根据检测触点的参数确定数据接口的接口标准；
S4：根据数据接口的接口标准配置导电针与识别电路中对应的通信触点电连接，以使得接口设备与电子设备进行通信。
例如，当检测到插头未连接到数据接口时，继续进行检测，直到检测到插头已连接到数据接口时，再进行步骤S2～S4。
例如，在步骤S3中，根据检测触点的参数确定数据接口的接口标准可以包括：
根据检测触点的参数确定数据接口的电触点数量；
利用参数与电触点定义的对应关系，查找与所述检测触点的参数对应的电触点定义；
根据电触点定义确定电触点顺序；
根据电触点数量、电触点定义和电触点顺序确定数据接口的接口标准。
应用本实施例提供的识别方法，可以实现在人眼无法辨别的环境如黑暗环境下，接口设备与不明接口标准的数据接口的自动通信连接，可以更加便捷地识别和连接手机等电子设备，快速实现对电子设备的充电和数据连接。
