当被保护器件 100上电时， 如图 3 ( b )所示， 电磁铁 3000通电产生磁 力， 杠杆 3003—端在电磁铁 3000引力的作用下被吸附， 而其另一端在杠 杆力的作用下将挡板 3001向上托起， 使挡板 3001向上移动， 将被保护器 件 100卡住， 使得被保护器件 100的取出受到限制。 此时， 弹性件 3002处 于形变的状态， 当被保护器件 100断电时， 弹性件 3002恢复正常状态， 将 挡板 3001恢复到初始位置， 即图 3 ( a )所示。
可以理解， 上图所示的各部件的形状结构仅是为便于画图， 不应理解 为是对各部件形状结构的唯一限定。
需要说明的是， 上述电磁铁在被保护器件 100处于带电状态时通电， 在实际应用中， 电磁铁可与被保护器件 100共用同一电源， 其好处是可使 电磁铁 3000与被保护器件 100同时通电和掉电， 使电子锁 102可更为有效 地实现对被保护器件 100 的上锁和解锁， 可以通过多种方式来实现电磁铁 与被保护器件 100共用同一电源， 例如， 可以将电磁铁安置在印刷电路板 ( PCB, Printed Circuit Board )上，该 PCB与被保护器件 100的电源处连接， 或者， 也可以直接通过导线将电磁铁与被保护器件 100 的电源处连接， 此 处不作限定。
由上可见， 本发明实施例中， 通过设计一种带有电子锁的壳体来装载 不允许热插拔的器件， 有效限制用户无意识地对被保护器件的热插拔操作， 提高了被保护器件的寿命， 同时， 该设计不需要通过任何电子芯片或程序 代码来实现， 具有成本低， 可靠性高的特点。
上述发明实施例中的电子式防热插拔装置是通过直接对被保护器件上 锁来实现对被保护器件的防热插拔保护的， 本发明实施例还提供了一种外 壳式的电子式防热插拔装置， 通过对壳体上锁来限制被保护器件的取出， 下面对本发明实施例的一种电子式防热插拔装置进行详细介绍。
一种电子式防热插拔装置， 包括： 壳体和电子锁；
其中， 上述壳体为外壳， 被保护器件可放置在壳体内， 当被保护器件 处于带电状态时， 由设置在壳体上的电子锁将壳体锁住， 以便于将被保护 器件锁住 , 限制被保护器件的取出。
在一种应用场景下， 上述壳体可包括可拆离的上壳和下壳， 上述电子 锁具体可以包括： 卡扣、 按钮、 电磁铁、 挡板以及弹性件；
在实际应用中， 被保护器件被放置在壳体中， 可通过卡扣将上壳和下 壳锁住， 使得上壳和下壳无法分离。 在被保护器件不带电的状态下， 可通 过按钮弹开卡扣， 取出被保护器件， 而在被保护器件带电的状态下， 按钮 因挡板的移动阻挡而无法被按下， 从而无法弹开卡扣， 限制了被保护器件 的取出。
其各部件的结构可如图 4 ( a )所示， 卡扣 4000与按钮 4001连接在一 起， 在按钮 4001移动的路径的上方放置挡板 4003 , 挡板 4003可由软磁体 (例如如铁、 钴或镍等材质）制成， 弹性件 4004 (如弹簧）一端固定在上 壳 401上， 另一端与挡板 4003连接， 在挡板 4003的下方放置电磁铁 4002。 当被保护器件断电时， 电磁铁 4002断电， 挡板 4003位于初始位置， 弹性 件 4004处于无形变的状态， 此时， 按钮 4001的移动路径不被挡板 4003阻 挡， 可按下按钮 4001弹开卡扣 4000, 使得上壳 401和下壳 402可分离开， 从而可取出被保护器件。
当被保护器件上电时， 如图 4 ( b ) 所示， 电磁铁 4002通电产生磁力， 挡板 4003受电磁铁 4002引力的作用向下移动， 使弹性件 4004产生形变， 同时， 向下移动的挡板 4003阻挡了按钮 4001的移动， 使得按钮 4001无法 被按下， 使得上壳 401和下壳 402不能够被分离， 从而无法取出被保护器 件。
可以理解， 上图所示的各部件的形状结构仅是为便于画图， 不应理解 为是对各部件形状结构的唯一限定。 基于上述实施例对各部件的功能性特 征的描述， 其各部件的位置关系及形状结构可以发生改变， 例如， 可将挡 板置于电磁铁的下方， 电磁铁在通电后将挡板吸附， 使得按钮无法被按下， 同样达到了本发明想要实现的技术目的， 此处不再——详述。
在一种应用场景下， 壳体可包括能够相互滑动的上壳和下壳， 电子锁 具体可以包括： 电磁铁、 挡板和弹性件； 在实际应用中， 被保护器件被放置在壳体中， 在被保护器件不带电的 状态下， 可通过滑动上壳或者下壳来打开壳体， 取出被保护器件， 而在被 保护器件带电的状态下， 上壳和下壳因挡板的移动阻挡而无法相互滑动， 从而无法打开壳体， 限制了被保护器件的取出。
其各部件的结构可如图 5 ( a )所示， 挡板 5001被放置在上壳 501中， 其可由软磁体（如铁、 钴或镍等材质）制成， 弹性件 5002 (如弹簧）一端 固定在上壳 501上，另一端与挡板 5001连接，电磁铁 5000放置在挡板 5001 的下方。 当被保护器件断电时， 电磁铁 5000断电， 挡板 5001位于初始位 置，弹性件 5002处于无形变的状态，此时，可通过滑动上壳 501和下壳 502 打开壳体， 取出被保护器件。
当被保护器件上电时， 如图 5 ( b ) 所示， 电磁铁 5000通电产生磁力， 挡板 5001受电磁铁 5000引力的作用向下移动， 使弹性件 5002产生形变， 同时，由于挡板 5001的向下移动，阻挡了上壳 501和下壳 502的相互滑动， 使得壳体不能够被打开， 从而无法取出被保护器件。
可以理解， 上图所示的各部件的形状结构仅是为便于画图， 不应理解 为是对各部件形状结构的唯一限定。 基于上述实施例对各部件的功能性特 征的描述， 其各部件的位置关系及形状结构可以发生改变， 例如， 可将挡 板置于电磁铁的下方， 电磁铁在通电后将挡板吸附， 使得按钮无法被按下， 同样达到了本发明想要实现的技术目的， 此处不再——详述。
需要说明的是， 上述电磁铁在被保护器件处于带电状态时通电， 在实 际应用中， 电磁铁可与被保护器件共用同一电源， 其好处是可使电磁铁与 被保护器件同时通电和掉电， 使电子锁可更为有效地实现对被保护器件的 防热插拔保护， 可以通过多种方式来实现电磁铁与被保护器件共用同一电 源， 例如， 可以将电磁铁安置在 PCB上， 该 PCB与被保护器件的电源处连 接， 或者， 也可以直接通过导线将电磁铁与被保护器件的电源处连接， 此 处不作限定。 综上， 本发明实施例中， 通过设计一种带有电子锁的壳体来装载不允 许热插拔的器件， 有效限制用户无意识地对被保护器件的热插拔操作， 提 高了被保护器件的寿命， 同时， 该设计不需要通过任何电子芯片或程序代 码来实现， 具有成本低， 可靠性高的特点。
以上所述的具体实施方式， 对本发明的目的、 技术方案和有益效果进 行了进一步详细说明， 所应理解的是， 以上所述仅为本发明的具体实施方 式而已， 并不用于限定本发明的保护范围， 凡在本发明的精神和原则之内， 所做的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
