Description

一种静电处理方法和装置 技术领域
本文涉及终端技术领域，尤其涉及一种静电处理方法和装置。
背景技术
静电作为一种普遍物理现象，近十多年来伴随着集成电路的飞速发展和高分子材料的广泛应用，静电的作用力、放电和感应现象引起的危害十分严重。静电并不是静止的电，是宏观上暂时停留在某处的电。人在地毯或沙发上立起时，人体电压也可高1万多伏，而橡胶和塑料薄膜行业的静电更是可高达10多万伏。任何两个不同材质的物体接触后再分离，即可产生静电。当两个不同的物体相互接触时就会使得一个物体失去一些电荷如电子转移到另一个物体使其带正电，而另一个物体得到一些剩余电子的物体而带负电。静电产生过程:若在分离的过程中电荷难以中和，电荷就会积累使物体带上静电。所以物体与其它物体接触后分离就会带上静电。秋冬季节由于气候干燥，静电现象比较普遍,静电瞬间的电压比较大，有时会对人体有比较大的影响。

本实施例中静电探头可以为导电金属件，例如可以为导电金属球，在消除静电时，让小球接触需要外界物体，达到引入静电电荷的目的。可选地，金属球可以为球型腔体形状，考虑到金属材质的导电率，本实施例可以选取导电性能较好的金属来制作静电探头；一般金属导电性的排序为:银→铜→金→铝→钨→镍→铁，本实施例从成本和性能综合考虑，选择铜为静电探头的材质。在制作金属球时，可选地，球面的厚度小于或等于0.5mm，这样有 利于转移电荷，达到一个更优的导电特性。
本实施例中静电传输电路可以由导线组成，导线设置成一端连接至静电探头，另一端在本实施例的装置设置到电子终端时可以连接至电子终端的地端，这样，导线即可将静电电荷形成的静电电流传输至地端，达到静电释放的目的。
可选地，所述装置还可以包括：设置于所述静电传输电路和所述地端之间的降压电路；
可选地，静电传输电路可以包括：所述电子终端的外设接口和导线；所述导线设置成一端与所述外设接口连接、另一端与所述降压电路连接，所述静电探头插在所述外设接口中。本实施例中外设接口可以包括：音频接口或者数据接口等。
例如当静电传输电路包括：耳机插口和导线时，此时静电探头可插入耳机插口中与耳机插口连接，由耳机插口将静电电荷形成的静电电流传输给导线，然后由导线将静电电流传输至地端，达到释放静电的目的。
应当理解的是：静电传输电路还可以由其他导电物体组成，例如金属片等，当然还可以由一些电路构成，例如由一个电阻串联的电路组成。
在电子终端中应用本实施例的静电处理装置，电子终端可以将外界物体上的静电电荷传输到自身的地端释放掉，这样电子终端就具有静电消除功能，可消除外界物体上的静电，防止静电对人体的伤害。

例如光告警电路可以为一个LED电路，该LED电路在接收到静电电流后，电路中的LED灯就会发亮或闪烁，此时用户就知道外界物体上带有静电。
为节省成本，本实施例可以使用电子终端自带的告警电路来进行告警，如可以使用电子终端自带的LED电路来告警；在实际应用中可以采用智能终端的键盘灯、摄像头的闪光灯或者充电指示灯来进行告警。
图3所示的静电处理装置，可以在消除静电的同时进行告警，提醒用户测试物体上带有静电。
可选地，为了避免大量的静电电流进入告警电路(例如LED电路)造成损坏，还可以设置一个微秒级别的时延开关。
实施例二：
如图4所示，本实施例提供了一种静电处理装置，应用于电子终端，包括：静电探头、静电传输电路、静电告警电路和降压电路；所述静电探头设置成与所述静电传输电路连接，所述静电传输电路设置成分别与所述静电告警电路、降压电路连接；
所述静电探头设置成与外界物体接触引入外界物体上的静电电荷；
所述静电传输电路设置成将引入的静电电荷形成的静电电流传输至静电告警电路和降压电路；
所述静电告警电路设置成在接收到静电电流后进行告警，并将自身电路的静电电流传输给降压电路；
所述降压电路设置成对输入的静电电流形成的静电电压进行降压处理，然后将降压处理后的静电电流传输至电子终端的地端。
本实施例提供的静电处理装置，可以检测外界物体上是否带有静电，如果带有静电，则进行告警提醒用户，并且释放外界物体上的静电，防止外界物体上的静电对人体产生伤害。
为了使得用户在需要进行静电检测和静电释放开启电子终端的静电检测和静电释放功能，进而提高用户体验；如图5所示，本实施例的静电处理装置还可以包括：第一开关电路，所述第一开关电路设置成一端与所述静电传输电路连接、另一端分别与所述静电告警电路和所述降压电路连接；
所述第一开关电路设置成控制静电传输电路与所述静电告警电路、降压电路之间的连通。
可选地地，本实施例中第一开关电路为一个开关元件，在开关闭合时静电传输电路与静电告警电路、降压电路之间连通；此时，静电传输电路可以将静电电流分别传输至静电告警电路和降压电路；
当开关断开时，静电传输电路与静电告警电路、降压电路之间的连接断开。
在图5所示的静电处理装置的基础上，为了能够在静电告警之后，可以选择是否进行静电释放，如图6所示，本实施例的静电处理装置还可以包括：设置于所述第一开关电路和所述降压电路之间的第二开关电路；所述第二开关电路设置成一端与所述第一开关电路连接、另一端与所述降压电路连接；所述第二开关电路设置成控制所述第一开关电路与所述降压电路之间的连通。可选地，第二开关电路可以为一个开关元件，当开关闭合时，第一开关电路与降压电路连通，当开关断开时第一开关电路与降压电路之间的连接断开。
图6所示的电路，在第一开关电路处于闭合状态时，静电电流可传输至静电告警电路，若外界物体上带有静电，则静电告警电路进行告警，此时用户知晓外界物体上带有静电，可选择开启第二开关电路使其处于闭合状态，对静电传输电路传输的静电电流形成的电压进行降压处理，然后将静电电流传输至地端。
考虑到在对静电降压之后，还是存在大量的静电电荷会影响静电释放，本实施例还可以对降压之后的静电电流进行缓冲，如图7所示，在上述静电处理装置的基础上，本实施例还可以包括：设置于所述降压电路和所述地端之间的静电缓冲电路；所述静电缓冲电路设置成减缓所述静电传输电路与所述地端之间的静电电流传输。图7所示的静电处理装置是在图4所示的装置 基础上增加静电缓冲电路，应当理解的是还可以在图5、6的基础上增加静电缓冲电路。
在本实施例中可以利用2个反向的二极管，TVS(瞬变电压抑制)二极管ESD(静电释放)保护处理瞬时脉冲对器件损害，将瞬时电流从敏感器件引开。当瞬时电压超过电路正常工作电压后，TVS二极管便发生雪崩，提供给瞬时电流一个超低电阻通路，其结果是瞬时电流通过二极管被引开，并且在电压恢复正常值之前使被保护回路一直保持截止电压。当瞬时脉冲结束以后，TVS二极管自动回复高阻状态，整个回路进入正常电压。许多器件在承受多次冲击后，其参数及性能会发生退化，而只要工作在限定范围内，二极管将不会发生损坏或退化。
可选地，如图8所示，本实施例中的降压电路可以包括：所述降压电路包括：第一串联电路、第二串联电路、第一静电输入端、第二静电输入端、第一静电输出端和第二静电出端；
所述第一串联电路和所述第二串联电路均由两个二级管构成，所述两个二极管的正极相连；所述第一串联电路中一个二极管的负极和所述第二串联电路中一个二极管的负极相连，所述第一串联电路中另一个二极管的负极和所述第二串联电路中另一个二极管的负极相连；所述第一串联电路的两个二极管的负极分别连接至所述第一静电输入端和第二静电输入端，所述第二串联电路的两个二极管的负极分别连接至所述第一静电输出端和第二静电输出端；
所述第一静电输入端设置成接收所述静电传输电路传输的静电电流；所述第二静电输入端设置成接收所述静电告警电路传输的静电电流；所述第一静电输出端、第二输出端设置成分别输出静电电流至所述地端。
在本实施例静电处理装置应用图8所示的降压电路的基础上，可选地，如图9所示，本实施例中静电缓冲电路可以包括电容；所述电容设置成两端分别与所述第一静电输出端、所述第二静电输出端连接。
可见本实施例采用了电容接地的方式泄放电路。静电被泄放到地端，也就是电荷被释放到地端后，就起到了对人体的保护作用。释放静电时，在电容上有一个升压过程，导致电容上积累大量电荷，这些电荷就是输入进来的 静电电荷，这些电荷在电容的两极上附着，当二极管通路打开后，这些电荷就自然从打开的通路泄放到地端，防止了对人身的静电危害。
根据上述描述，如图10所示，本实施例提供了一种静电处理装置，应用于智能终端，包括：插入在耳机插孔中的球形金属、开关1、开关2、图8所示的降压电路、电容、LED电路；其中耳机插孔、耳机插孔与开关1之间导线组成了静电传输电路；
在开关1闭合时耳机插孔与LED电路连接，当测试物体上有静电时，球形金属接触测试物体会吸收静电，并传输给LED电路，此时LED灯会发光或闪烁，用户知晓测试物体静电，然后闭合开关2，球形金属将吸收到的静电传递给降压电路，此时降压电路的两个输入端分别接收球形金属传输的静电和LED灯所在支路传输的静电，对静电进行降压；最后电容上积累大量电荷，这些电荷就是输入进来的静电电荷，这些电荷在电容的两极上附着，当二极管通路打开后，这些电荷就自然从打开的通路泄放到地端，防止了对人身的静电危害。
实施例三：
如图11所示，本实施例提供了一种静电处理方法，应用于电子终端，包括如下步骤：
步骤101：静电探头与外界物体接触引入外界物体上的静电电荷；
步骤102：静电传输电路将引入的静电电荷形成的静电电流传输至所述电子终端的地端。
应用本实施例静电处理方法，电子终端可具有消除静电功能，防止静电对人体伤害。
工业实用性
