第一锁杆2在第一壳体31内，一端与驱动装置1的输出端连接，可以是同轴连接，也可以是垂直连接，能够在驱动装置1的带动下进行转动，另一端伸出第一锁孔312用于锁定或者解锁。根据实际的需要，第一锁孔312的位置可以设置在第一壳体31端部的各个方向，可以在顶面，也可以设置在第一壳体31的侧面，第一锁杆2的形状也可以设计成各种形状，如本实施例的L型。本实施例中第一锁杆2和输出端垂直连接。驱动装置1与第一壳体31连接处的第一通孔311设置有第一密封装置313，用于防止水或灰尘进入密封本体3。第一锁孔312上设置有第二密封装置314也用于防止水或灰尘进入密封本体3。密封本体3和密封盖体4采用密封的连接方式，使整体的密封效果能够达到 IPX6K级。
进一步的，所述密封本体3及所述密封盖体4通过焊接连接，所述焊接为摩擦焊接、超声波焊接、激光焊接、电子束焊接、热压焊接中的一种或几种。
摩擦焊接方式，是指利用工件接触面摩擦产生的热量为热源，使工件在压力作用下产生塑性变形而进行焊接的方法。
超声波焊接方式，是利用高频振动波传递到两个需焊接的物体表面，在加压的情况下，使两个物体表面相互摩擦而形成分子层之间的熔合。
激光焊接方式，是利用高能量密度的激光束作为热源的一种高效精密焊接方法。
电子束焊接方式，是指利用加速和聚焦的电子束轰击置于真空或非真空中的焊接面，使被焊工件熔化实现焊接。
热压焊接方式，是对焊件施加压力，使接合面紧密地接触产生一定的塑性变形而完成焊接的方法。
在一些实施例中，还包括设置在所述密封本体3及所述密封盖体4之间的第三密封装置315，如图2所示，所述密封本体3及所述密封盖体4通过卡接、拼接、螺接或铆接中的一种或几种方式进行连接。第三密封装置315可以为橡胶质地，设置在密封本体3和密封盖体4之间，能有效的起到密封的作用。
进一步的，所述第一壳体31与所述驱动装置1通过卡接、拼接、螺接或铆接中的一种或几种方式进行连接。
螺接方式，是指螺纹连接，用螺纹件(或被连接件的螺纹部分)将被连接件连成一体的可拆卸连接。常用的螺纹联接件有螺栓、螺柱、螺钉和紧定螺钉等，多为标准件。
卡接方式，是指在要连接的两端上分别设置对应的卡爪或卡槽，通过卡槽和卡爪进行装配，使其连接在一起。卡接的方式优点是连接快速，可拆卸。
拼接方式，是指在要连接的两端上分别设置对应的凹槽和凸起，通过凹槽和凸起相互榫接或拼接进行装配，使其连接在一起。拼接的方式优点是连接稳定，可拆卸。
铆接方式，即铆钉连接，是利用轴向力将零件铆钉孔内钉杆墩粗并形成钉头，使要连接的两端相连接的方法。
在一些实施例中，电子锁锁杆密封结构还包括与所述驱动装置1依次连接的连接杆5和第二锁杆6，如图4、图5和图6所示，所述密封本体3还包括与所述第一壳体依次连接的第二壳体32和第三壳体33，所述连接杆5设置在所述第二壳体32中，所述第二锁杆6设置在所述第三壳体33中，所述第三壳体33还设置第二锁孔331和第四密封装 置332，所述第二锁杆6一端与所述连接杆5连接，另一端穿过所述第二锁孔331，并通过所述第四密封装置332与所述第二锁孔331密封连接。
连接杆5一端与驱动装置1的输出端连接，另一端与第二锁杆6连接。这样，驱动装置1就可以同时带动第一锁杆2和第二锁杆6完成两个锁的同步控制。连接杆5设置在第二壳体32内，第二锁杆6设置在第三壳体33内，第二锁杆6的一端穿过第二锁孔331上设置的第四密封装置332。第四密封装置332能够有效防止水或灰尘从第二锁孔331进入第三壳体33。
进一步的，所述第一密封装置313与所述第一壳体31的最大间隙小于520nm，所述第二密封装置314与所述第一壳体31的最大间隙小于520nm，所述第三密封装置315与所述密封本体3及所述密封盖体4的最大间隙小于520nm，所述第四密封装置332与所述第三壳体33的最大间隙小于520nm。
为了验证各个密封装置与临近器件间隙的大小对密封等级的影响，发明人采用干空气法对密封装置进行测试，通过抽真空或者空气加压，控制被测样品内外压力不同，若存在泄露，内外压力之差将缩小。通过检测空气压力变化可检测密封性。检测介质为干空气，无毒无害，不破坏被测品，同时检测环境干净整洁。以检测第四密封装置332与第三壳体33的密封情况为例，发明人将其他连接处完全密闭，选用不同密封程度的第二锁孔331的密封结构，将密封结构中的干空气部分抽出，使密封结构内的气压低于外部气压，持续检测密封结构内部气压，发现气压升高为不合格，测试结构如表1所示。
表1，第四密封装置332与所述第三壳体33的最大间隙对气压变化的影响
Figure PCTCN2022122087-appb-000001
从表1可知，当第四密封装置332与所述第三壳体33的最大间隙超过520nm后，气压发生变化，意味着有气体进入密封结构，测试不合格。所以发明人选用第四密封装置332与所述第三壳体33的最大间隙不小于520nm。
在一些实施例中，所述第一锁孔312的半径为3mm-15mm，所述第二锁孔331的半径为3mm-15mm，所述第一通孔311的半径为6mm-370mm。
第一锁孔312或第二锁孔331的半径过小，只能选择更细的第一锁杆2和第二锁杆6，而第一锁孔312或第二锁孔331的半径过大，则需要相应的增加整个密封结构的体积， 难以进行实际生产。
以第一锁孔312为例，发明人为了寻找合适的半径进行了相关测试。发明人选用不同半径的第一锁孔312并选择与之相匹配的第一锁杆2。选择不同半径的第一锁杆2，以聚氯乙烯材质的第一锁杆2为例，对第一锁杆2进行弯折实验，由于半径过小导致弯折实验中发生弯折为不合格。再进行工作测试，选择不同的第一锁杆2，其他结构相同，进行开关锁测试，由于锁杆半径过大导致和其他部件碰触发生异响为不合格，测试结果如表2所示。
表2，不同半径的第一锁孔312所对应的第一锁杆2的弯折情况及是否异响
Figure PCTCN2022122087-appb-000002
如表2所示，当第一锁孔312的半径小于3mm后，与其匹配的第一锁杆2的强度下降很多，极易在一些磕碰中发生弯折影响正常使用。而当第一锁孔312的半径大于15mm后，与其匹配的第一锁杆2的半径也因为增大而极易和其他器件碰触发生异响，也为不合格。同样，第二锁孔331和第一通孔311也是如此，因此，发明人选用第一锁孔312的半径为3mm-15mm，第二锁孔331的半径为3mm-15mm，第一通孔311的半径为6mm-370mm。
在一些实施例中，所述第一壳体31、所述第二壳体32和所述第三壳体33一体成型。一体成型的设计能够减少需要密封的连接处，更有利于整个密封本体的密封效果。
在一些实施例中，所述第一通孔311沿所述第二壳体32的延伸方向设置在所述第一壳体31上，如图7所示。这样驱动装置1的输出端能够和连接杆5同轴连接，这样连接处可以设置在密封本体3内，也可以设置在密封本体3外，能够满足不同的装配环境的需要。
进一步的，所述第一密封装置313为设置在所述第一壳体31和所述驱动装置1之间的密封垫，所述密封垫上设置第二通孔，所述第二通孔的直径大于等于所述第一通孔311的直径；或者所述第一密封装置313为外侧面具有凹部的密封环，所述凹部与所述第一通孔311边缘贴合。
更进一步的，所述第二密封装置314或第四密封装置332为设置在所述第一锁孔312或所述第二锁孔331一侧的密封垫，所述密封垫上设置第三通孔，所述第三通孔与所述第一锁杆2或所述第二锁杆6过盈配合；或者所述第二密封装置314或第四密封装置332为外侧面具有凹部的密封环，所述凹部与所述第一锁孔312或所述第二锁孔331边缘贴合，所述密封环的内孔与所述第一锁杆2或所述第二锁杆6过盈配合。
密封垫能够更进一步的提升第一壳体31和驱动装置1之间、锁孔与锁杆之间的密封性能，密封环也能起到同样的效果，密封环的外侧设置凹部，凹部能够和第一锁孔312及第二锁孔331匹配贴合。过盈配合能够使第一锁杆2和第二锁杆6与第三通孔或密封环具有更好的贴合性。
再进一步的，所述密封垫或所述密封环材质为泡沫棉或弹性橡胶或硅胶。泡沫棉或弹性橡胶或硅胶具有足够的密封性能又有良好的弹性，能够起到非常好的密封作用。
在一些实施例中，所述密封本体3及所述密封盖体4为塑料材质或橡胶材质。电子锁在使用时一般处于电流比较大的环境下，如果出现火花很容易发生危险，所以采用塑料材质的密封本体3和密封盖体4能够有效降低风险。
具体的，所述密封本体3及所述密封盖体4的材质含有聚氯乙烯、聚乙烯、聚酰胺、聚四氟乙烯、四氟乙烯/六氟丙烯共聚物、乙烯/四氟乙烯共聚物、聚丙烯、聚偏氟乙烯、聚氨酯、聚对苯二甲酸、聚氨酯弹性体、苯乙烯嵌段共聚物、全氟烷氧基烷烃、氯化聚乙烯、聚亚苯基硫醚、聚苯乙烯、交联聚烯烃、乙烯/醋酸乙烯共聚物、交联聚乙烯、聚碳酸酯、聚砜、聚苯醚、聚酯、酚醛树脂、脲甲醛、苯乙烯-丙烯腈共聚物、聚甲基丙烯酸酯、聚甲醛树酯中的一种或多种。
以聚甲醛、聚碳酸酯和聚酰胺为例：聚甲醛是一种表面光滑、有光泽的、硬而致密的材料，呈淡黄或白色，可在-40-100℃温度范围内长期使用。它的耐磨性和自润滑性也比绝大多数工程塑料优越，又有良好的耐油、耐过氧化物性能。
聚碳酸酯，无色透明，耐热，抗冲击，阻燃BI级，在普通使用温度内都有良好的机械性能。同性能接近的聚甲基丙烯酸甲酯相比，聚碳酸酯的耐冲击性能好，折射率高，加工性能好，不需要添加剂就具有很高级的阻燃性能。
聚酰胺，具有无毒、质轻、优良的机械强度，具有较好的耐磨性及耐腐蚀性，可代替铜等金属应用在机械、化工、仪表、汽车等工业中制造轴承、齿轮、泵叶及其他零件。密封本体3和密封盖体4需要高强度、高耐温、高耐磨等特性。因此，聚碳酸酯或聚酰胺为密封本体3和密封盖体4的首选。
虽然已经通过例子对本实用新型的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本实用新型的范围。本领域的技术人员应该理解，可在不脱离本实用新型的范围和精神的情况下，对以上实施例进行修改。本实用新型的范围由所附权利要求来限定。
