 本发明的实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
本发明为一种应用于锁具的自锁结构，包括锁栓1、锁栓弹簧2、限位组件3、蜗杆4、驱动装置5和滑块6。
锁栓1用于活动限位锁具的锁舌7。
锁栓弹簧2与锁栓1相对设置，用于顶出锁栓1以限位锁舌7。
限位组件3设置在锁栓1的轴向端部，用于限位锁栓1以防止其缩回。
蜗杆4的轴线方向与锁栓1的轴线方向相垂直。
驱动装置5用于驱动蜗杆4旋转。
滑块6与蜗杆4啮合，并与限位组件3接触，蜗杆4的旋转带动滑块6沿蜗杆4的轴线方向移动，滑块6的移动推动限位组件3以解除对锁栓1的限位。
进一步细化的方案中：上述驱动装置5为减速电机，具有较大的输出扭矩，进一步提高自锁结构的安全性，并且可靠耐用、节省空间、能耗低。
上述滑块6设置有一滑接部61，滑接部61与蜗杆4的螺纹槽41匹配，蜗杆4旋转的过程中滑接部61在螺纹槽41内滑动，以驱动滑块6实现移动。
本发明还包括锁体8，锁体8包括用于装配锁舌7的第一容腔81、用于装配锁栓1的第二容腔82、用于装配驱动装置5的第三容腔83，以及用于装配限位组件3的第四容腔84。
本发明还包括缓冲组件9，缓冲组件9垂直设置在锁栓1的侧边，用于分解锁栓1受到的外部冲击力，进一步起到防暴力开锁、缓冲减震的作用，进而保护后端的限位组件3及其相应连接的结构。本实施例中，缓冲组件9包括缓冲块91和缓冲弹簧92，缓冲弹簧92用于提供弹力使得缓冲块91抵在锁栓1的侧边；锁体8还包括用于装配缓冲组件9的第五容腔85。
参考图1至图6所示，示出了本发明的第一实施例。
上述限位组件3包括第一挡块31、第二挡块32和第三挡块33。第一挡块31用于限位锁栓1，第二挡块32用于限位第一挡块31，第三挡块33用于限位第二挡块32，滑块6用于限位第三挡块33，驱动装置5工作时蜗杆4带动滑块6移动，并依次推动第三挡块33解除对第二挡块32的限位、推动第二挡块32解除对第一挡块31的限位、推动第一挡块31解除对锁栓1的限位，锁栓1可让位锁舌7的运动以达到开锁的目的。
上述第一挡块31沿垂直于锁栓1的方向设置在锁栓1的端部；第二挡块32沿垂直于第一挡块31的方向与第一挡块31相对设置，第一挡块31设置有凹槽311，第二挡块32插入凹槽311以对第一挡块31限位；第三挡块33沿垂直于第二挡块32的方向与第二挡块32相对设置，第二挡块32设置有凸台321，第三挡块33抵在凸台321以对第二挡块32限位。
上述限位组件3还包括第一弹簧34、第二弹簧35和拉簧36。第一弹簧34用于使第一挡块31复位至限位锁栓1的位置；第二弹簧35用于使第二挡块32复位至限位第一挡块31的位置；拉簧36设置在滑块6与第三挡块33之间以使第三挡块33复位至限位第二挡块32的位置。
上述第一挡块31设置有第一凸部312，第二挡块32设置有第二凸部322，滑块6的端面上设置有台阶62和斜面63，第一凸部312与台阶62相对设置、第三挡块33的端部抵在滑块6的端部，第二凸部322与斜面63相对设置，滑块6受蜗杆4驱动而移动时，滑块6先推动第三挡块33移动并解除对第二挡块32的限位，再由斜面63接触第二凸部322以推动第二挡块32移动并解除对第一挡块31的限位，最后由台阶62接触第一凸部312以推动第一挡块31移动并解除对锁栓1的限位。
参见图5和图6，上锁状态时，滑块6通过拉簧36拉紧第三挡块33，防止第二挡块32向右运动，第二挡块32在第二弹簧35的作用下始终靠左，第二挡块32插入第一挡块31的凹槽311中，阻止第一挡块31向下运动，第一挡块31在第一弹簧34的作用下始终靠上，从而挡住锁栓1向右运动，从而无法开锁；开锁状态时，蜗杆4旋转，滑块6推动第三挡块33向下运动，取消对第二挡块32的限位后，滑块6再推动第二挡块32向右运动，取消对第一挡块31的限位后，滑块6进而推动第一挡块31向下运动，最终取消对锁栓1的限位，锁栓1可以向右移动；再次上锁时，蜗杆4拉动滑块6向上运动，首先第二挡块32在第二弹簧35的作用下复位，然后第一挡块31在第一弹簧34的作用下复位，最后第三挡块33在拉簧36的作用下复位。
第一实施例通过第一挡块31、第二挡块32、第三挡块33与滑块6的联动关系，依次实现三层限位关系，并由第一挡块31最终限位锁栓1，由于第一挡块31与第二挡块32是相对垂直，在驱动装置5不工作的情况下两者由于第三挡块33的限位关系保持静止，从而保证锁体8无论受到哪个方向的撞击力都不会使第一挡块31、第二挡块32晃动而脱离限位位置，暴力开锁的可能性为0。
参考图7至图10所示，示出了本发明的第二实施例。
上述限位组件3包括第四挡块37和第三弹簧38。第四挡块37设置在锁栓1的轴向端部，并设置有让位锁栓1轴向移动的让位缺口371，第三弹簧38用于使第四挡块37移动至让位缺口371与锁栓1端部相对的位置；滑块6用于限位第四挡块37，以使第四挡块37保持对锁栓1的限位；驱动装置5工作时蜗杆4带动滑块6移动，以解除对第四挡块37的限位，第三弹簧38推动第四挡块37移动以解除对锁栓1的限位，锁栓1可让位锁舌7的运动以达到开锁的目的。
上述滑块6设置有用于限位第四挡块37的第三凸部64，滑块6移动时第三凸部64可推动第四挡块37移动。
第二实施例中还包括行程开关10，与锁具的锁舌7相对设置，用于感应锁舌7的上锁位置，并发送上锁信号给驱动装置5实现上锁，用户转动锁舌7时即可自动上锁，操作更加简便。
参见图9和图10，上锁状态时，利用蜗杆4与滑块6的配合实现自锁，驱动装置5不工作时滑块6的位置锁死，从而保证第四挡块37的位置锁死，以实现对锁栓1的限位；开锁状态时，蜗杆4旋转带动滑块6移动，第三弹簧38将第四挡块37推向滑块6的方向，从而使让位缺口371对准锁栓1的端部，锁栓1插入让位缺口371以让位锁舌7的运动，达到开锁的目的。
第二实施例通过第四挡块37与滑块6的联动关系，上锁时滑块6带动第四挡块37复位至限位锁栓1的状态，开锁时滑块6让位第四挡块37的运动以使让位缺口371对准锁栓1的端部，以解除对锁栓1的限位；并且，当锁栓1插入让位缺口371后实现对第四挡块37的限位，用户即使放松锁舌7也无需再重新输入密码，在设定时间内均可以开锁，使用更加方便。
参考图11至图14所示，示出了本发明的第三实施例，第三实施例相对于第二实施例在限位组件3的具体实施方式上有一定区别。
上述限位组件3包括第五挡块39。第五挡块39设置在锁栓1的周向端部，滑块6与第五挡块39连接；驱动装置5工作时蜗杆4带动滑块6移动，第五挡块39与滑块6同步移动以解除对锁栓1的限位，锁栓1可让位锁舌7的运动以达到开锁的目的。
上述滑块6设置有卡块65，第五挡块39设置有供卡块65配合的卡槽391，卡块65插置在卡槽391中，以实现第五挡块39与滑块6的同步移动。
参见图13和图14，上锁状态时，利用蜗杆4与滑块6的配合实现自锁，驱动装置5不工作时滑块6的位置锁死，从而保证第五挡块39的位置锁死，以实现对锁栓1的限位；开锁状态时，蜗杆4旋转带动滑块6移动，滑块6带动第五挡块39移动，从而解除对锁栓1的限位以让位锁舌7的运动，达到开锁的目的。
第三实施例通过第五挡块39与滑块6的联动关系，滑块6带动第五挡块9同步移动，以限位或解锁锁栓的移动；通过第五挡块39与滑块6的分体设计，可以避免锁体受撞击时力直接传递至蜗杆4，起到保护作用；由滑块6直接带动第五挡块9移动，联动结构少、功耗低、锁具反应迅速。
通过上述方案，本发明通过蜗杆4与滑块6的配合，利用蜗杆4的自锁原理对滑块6限位，进而通过滑块6对限位组件3的限位达到限位锁栓1的目的，形成锁具内部的自锁功能，只要驱动装置5不工作，滑块6就处于锁死状态，从而杜绝电子锁具被撞击而开锁的风险，真正地实现了电子锁具的防撞保险。
上述实施例和图式并非限定本发明的产品形态和式样，任何所属技术领域的普通技术人员对其所做的适当变化或修饰，皆应视为不脱离本发明的专利范畴。
