下面结合图1至图8，对本发明实施例一提供的一种光模块解锁装置的各组成部件的结构、安装方式以及工作原理进行说明。
结合本发明实施例一，参与图7和图8，光模块解锁装置包括拉环1和底座2，在实际应用场景中，光模块解锁装置是组装在光模块中的，光模块中设置有电路板，将光模块锁定在屏蔽笼中以实现光互联；在需要将光模块从屏蔽笼移出时，通过拉拔光模块解锁装置的拉环1可以顶开屏蔽笼弹片，将光模块从屏蔽笼中移出，以实现光模块的解除锁定。
结合本发明实施例一，参阅图1至图4，对拉环1的结构进行说明。拉环1包括手柄109和解锁部件108；通过手柄109施加拉拔力可以实现对拉环1进行拉拔，进而实现解锁部件108顶开与之接触的屏蔽笼弹片，实现解锁。解锁部件108包括至少一个解锁块(101，102)、至少一个折弯部(103,104)和分别设置在两侧的肋板110上的导向槽106以及设置在肋板111上的导向槽105。至少一个折弯部(103,104)设置在解锁部件108上与手柄109接触的一侧，至少一个解锁块(101，102)设置在解锁部件108上远离手柄109的一侧，同时，至少一个折弯部(103,104)和至少一个解锁块(101，102)分别设置在解锁部件108上相对设置的两端。在至少一 个折弯部(103,104)上均设置有回弹凸起，折弯部103上设置有回弹凸起1031，回弹凸起1031向手柄109一侧凸出；折弯部104上设置有回弹凸起1041，回弹凸起1041向手柄109一侧凸出。在解锁部件108上还设置有长臂107，长臂107与至少一个解锁块(101，102)连接。拉环1为弹性材质一体成型制作，一实施例中，拉环1的弹性材质可以为PEI塑料或LCP塑料，其中，PEI塑料为聚醚酰亚胺塑料Polyetherimide，LCP塑料为液晶聚合物Liquid Crystal Polymer。
结合本发明实施例一，参阅图5至图6，对底座2的结构进行说明。底座2是一个长方形壳体，底座2上包括至少一个斜槽(201,202)、至少一个挡板(203,204)和设置在底座2两侧的导向柱205和导向柱206。至少一个斜槽(201,202)和至少一个解锁块(101，102)的数量相同，每个斜槽均由一个凹槽和一个斜边构成，例如，斜槽201包括斜边2011，斜槽202包括斜边2021。解锁部件108可以在底座2上相对滑动，并带动至少一个解锁块(101,102)滑入至少一个斜槽(201,202)后隐入至少一个斜槽(201,202)槽底，此时光模块处于锁定状态；或者与至少一个斜槽(201,202)的至少一个斜边(2011,2021)抵接后凸起，顶开屏蔽笼的弹片，此时光模块实现解锁。
在底座2上还设置有至少一个斜块(207,208)，至少一个斜块(207,208)的至少一个倾斜面分别和至少一个斜槽(201,202)的至少一个斜边(2011,2021)所在的平面重合，以便于提升至少一个解锁块(101,102)与至少一个斜边(2011,2021)抵接凸起后的上表面的第二高度，使第二高度高于凸块209上表面的第一高度，实现光模块解锁装置的解锁。至少一个挡板(203,204)和至少一个折弯部(103,104)数量相同，至少一个挡板(203,204)用于对至少一个折弯部(103,104)进行限位，使得至少一个折弯部(103,104)在弹力作用下带动拉环1回弹。在底座2上还设置有滑移 槽210，在解锁部件108安装到底座2上后，滑移槽210和长臂107位置耦合，即长臂107可沿滑移槽210相对滑动。
结合本发明实施例一，参阅图7和图8，对组成光模块解锁装置的拉环1和底座2的位置或连接关系进行说明。在本实施例一中，以解锁块数量和斜槽数量均为2个进行说明，但本实施例一中解锁块和斜槽数量不限定为2个，例如解锁块和斜槽数量还可以为1个，在此不对解锁块和斜槽数量做过多限定，本领域普通技术人员在解锁块和斜槽数量上作出的改进，仍属于本发明的保护范围。
在拉环1的解锁部件108安装到底座2上后，解锁块101和斜槽202的槽底接触，解锁块101的第一斜面1011和斜槽202的斜边2021相抵接；解锁块102和斜槽201的槽底接触，解锁块102的第二斜面1021和斜槽201的斜边2011相抵接。长臂107和滑移槽210位置耦合，即长臂107位于滑移槽210中且可沿滑移槽210相对滑动。导向槽105和导向柱206位置耦合，即导向柱206位于导向槽105中，导向槽105和导向柱206之间可相对滑动；导向槽106和导向柱205位置耦合，即导向柱205位于导向槽106中，导向槽106和导向柱205之间可相对滑动。折弯部103被挡板204限位，折弯部103的回弹凸起1031和挡板204之间为过盈配合；折弯部104和折弯部103的结构相同，折弯部104被挡板203限位，折弯部104的回弹凸起1041和挡板203之间为过盈配合。在拉环1上还设置有第一通槽112和第二通槽113，在底座2上还设置有与第一通槽112和第二通槽113相耦合的第一立柱211和第二立柱212，第一立柱211和第一通槽112之间可相对滑动，第二立柱212和第二通槽113之间可相对滑动。
结合本发明实施例一，参阅图7，对拉环1和底座2组装成光模块解锁装置的方式进行说明。将拉环1的解锁部件108面向底座2，肋板111与导向柱206对应，肋板110与导向柱205对应，按压解锁部件108，使导向柱 206撑开肋板111，导向柱205撑开肋板110，使得导向柱206进入导向槽105中以及导向柱205进而导向槽106中，然后肋板110和肋板111在自身弹力作用下回弹，与底座2的两侧侧壁贴合；同时可以实现，解锁块101进入斜槽202的槽底，解锁块102进入斜槽201的槽底，折弯部103被挡板204限位，折弯部104被挡板203限位。
需要说明的是，为了拉环1的解锁部件108能够更方便省力的和底座2卡接，在导向柱205和导向柱206上均设置有倾斜面，便于顺利撑开肋板110和肋板111，使得导向柱205进入导向槽106以及导向柱206进入导向槽105。同时，在挡板203和挡板204也均设置有倾斜面，便于折弯部103的回弹凸起1031和折弯部104的回弹凸起1041顺利与挡板203和挡板204实现过盈配合。
结合本发明实施例一，参阅图7至图10，以下对安装在光模块上的光模块解锁装置的工作状态进行说明。
在光模块解锁装置安装到光模块上后，当拉环1的解锁部件108在底座2上处于初始状态时，即拉环1的手柄109在不受外力拉拔的状态下时，如图8和图9所示，由于拉环1为弹性材质制作，折弯部103和折弯部104分别被挡板204和挡板203限位，在回弹凸起1031和回弹凸起1041发生变形后的弹力作用下，解锁块101和解锁块102分别滑入斜槽202和斜槽201的槽底。同时，解锁块101和解锁块102位于底座2上凸块209的下方，此时拉环1的解锁部件108尚未实现顶开与之接触的屏蔽笼弹片，因而光模块处于锁定状态。需要说明的是，虽然在说明书附图中没有展示屏蔽笼弹片的位置，本领域普通技术人员仍然可以根据本领域的现有技术获知屏蔽笼弹片的设置位置。
在通过对手柄109向外施加拉拔力时，可以实现解锁部件108的解锁块101和解锁块102分别与斜槽202的斜边2021和斜槽201的斜边2011 抵接后凸起，达到解锁块101和解锁块102凸起后的上表面高度高于底座2的凸块209上表面的第一高度，从而能够顶开与之配合的屏蔽笼弹片，实现光模块从屏蔽笼中解锁进而拔出光模块。
具体的，在外力作用下对手柄109施加拉拔力时，解锁部件109能够在底座2上相对滑动，滑动方向是向屏蔽笼外侧滑动，导向槽105沿着导向柱206滑动，导向槽106沿着导向柱205滑动，长臂107沿着滑移槽210滑动，第一通槽112沿着第一立柱211滑动，第二通槽113沿着第二立柱212滑动，折弯部103的回弹凸起1031在挡板204的限位作用下发生变形，折弯部104的回弹凸起1041在挡板203的限位作用下发生变形。在解锁块101和解锁块102凸起后的上表面高度高于底座2的凸块209上表面的第一高度时，解锁块101和解锁块102将屏蔽笼弹片的顶出高度高于凸块209上表面的第一高度，实现光模块从屏蔽笼中解锁进而拔出光模块。
在一个具体的实施方式中，为了提升解锁块101和解锁块102分别与斜槽202的斜边2021和斜槽201的斜边2011抵接后凸起的上表面高度，在底座2上还设置有斜块208和斜块207，斜块208的倾斜面和斜边2021所在的平面重合，斜块207的倾斜面和斜边2011所在的平面重合，以便于提升解锁块101和解锁块102与斜边2021和斜边2011抵接后凸起的上表面的第二高度，使所述第二高度高于所述凸块209上表面的第一高度，实现所述光模块解锁装置的解锁。
在光模块从屏蔽笼中拔出后，停止给拉环1的手柄109施加外力，在折弯部103的回弹凸起1031和折弯部104的回弹凸起1041发生变形后的弹力作用下，拉环1整体回弹，带动解锁部件108再次处于初始状态，解锁块101和解锁块102分别滑入斜槽202和斜槽201后隐入斜槽202和斜槽201的槽底。
结合本发明实施例一，参阅图1至图6，拉环1和底座2均设计为轴对 称零件，加工制造方便；同时，由于拉环1为弹性材质制作，在光模块解锁装置的解锁过程中会利用拉环1的解锁部件108在弹力作用下回弹，拉环1设计为轴对称零件能够保证拉环1两侧受到的弹力均衡。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
