图12为一种实施方式的制造方法流程图。
 本发明的实施方式
具体实施方式
现有的埋入式道钉，透明盖板和底壳之间仅靠防水胶圈做防水，再加上透明盖板和底壳围成的内部空间有很大的空隙，里面有空气，在受到户外环境影响埋入式道钉热胀冷缩的情况下以及防水胶圈老化的情况下，埋入式道钉内部会进入水汽或液体，从而腐蚀电路，造成电路老化、短路，从而影响产品寿命。
在本发明实施例中，埋入式道钉将带有杯状结构的底壳通过密封圈与透明盖板固定连接，形成内置腔室，底壳的侧板和透明盖板的挡板紧密贴合卡接，内置腔室具有灌封胶，固化后的灌封胶密封了埋入式道钉，具有密封防水和抗压效果。
下面以埋入式太阳能道钉为例结合附图作进一步详细说明。
请参考图2-图11，埋入式太阳能道钉包括底壳1、透明盖板2、发光模块、控制模块、储能模块、密封圈5、螺钉6和太阳能板7，其中发光模块为LED道钉灯3，控制模块为电路板4，储能模块可以为电池或电容器，本实施例中的储能模块为电池8，此外LED道钉灯3被装入LED灯罩9中。发光模块、储能模块、太阳能板的连接部均与控制模块连接，即在本实施例中的LED道钉灯3、电池8和太阳能板7的连接线或正负极均与电路板4连接。透明盖板2安装在底壳1的上端，并且与底壳1围成了内置腔室100，底壳1为包括侧板11和底板12的杯状结构，透明盖板2的下表面设有垂直向下延伸的挡板21，该挡板21为环形结构，挡板21和透明盖板2为一体成型结构，透明盖板2的挡板21与底壳1的侧板11贴合。内置腔室100填充有固化后的灌封胶101，且LED道钉灯3、电路板4、太阳能板7、电池8和LED灯罩9都位于内置腔室100中。灌封胶101具有三层，分别为包裹住LED道钉灯3的第一层灌封胶101a,包裹住太阳能板7的第二层灌封胶101b,包裹住电路板4和电池8的第三层灌封胶101c，其中，第一层灌封胶101a和第二层灌封胶101b都是透明的灌封胶。
如图3至如6所示，底壳1的侧板11的内侧面设有凹槽，透明盖板2的挡板21的外侧面设有对应的凸起，底壳1的侧板11的内侧面设有凸起，挡板21的外侧面也设有对应的凹槽，侧板11和挡板21通过设置的凸起或凹槽能够卡接固定底壳1和透明盖板2的位置，防止两者转动，以使得侧板11与挡板21能够相互紧密贴合卡接，也具有一定的密封效果。底壳1的侧板11的外侧面设有加强筋13，底壳1和加强筋13是压铸一体成型的结构，底壳1可以是铝合金外壳，铝合金外壳具有较高强度且耐腐蚀性能稳定，当车辆碾压道钉时，加强筋13一定程度上承受其周边的压力，增强了整个道钉的抗压能力。底壳1的底板12中心设有注胶孔14，用于向道钉的内置腔室100内注入灌封胶101，注胶孔14的周围分布着多个排气孔15，当向注胶孔14内灌胶时，内置腔室100中的气体受到压力从排气孔15排除，减小内置腔室100中的气体，有助于灌封胶101固化后密封和固定整个内置腔室100。
埋入式道钉的密封圈5安装在底壳1和透明盖板2的连接处，密封圈5可以为防水胶圈，也可以为其他具有密封效果的防水垫，主要作用是用于密封底壳1和透明盖板2连接处之间的缝隙。透明盖板2的边缘设置了多个沉头孔22，底壳1的边缘设有与沉头孔2对应的多个螺孔16，密封圈5上也具有相应的供螺钉6穿过的多个孔，沉头孔22上的螺钉6将沉头孔22、密封圈5和螺孔16依次紧固连接，所以螺钉6也将透明盖板2、密封圈5和底壳1紧密地固定在一起，一定程度上防止液体从底壳1的和透明盖板2连接处的缝隙进入内置腔室100中。当制作道钉工艺中的最后一次灌胶，灌封胶101c把内置腔室100填充满时，这个缝隙处具有灌封胶101c，这是在填充满内置腔室100过程中，灌封胶11没过透明盖板2的挡板21所围成的区域后流到此处，此时密封圈5、底壳1的侧板11和透明盖板2的挡板21的紧密贴合卡接以及侧板11和挡板22缝隙处的灌封胶，这三者显著提高了透明盖板2和底壳1连接处之间的密封性能和防水性能。此外，底壳1的底板12上的注胶孔14和排气孔15内也可以具有灌封胶101，灌封胶101c把内置腔室100填充满时，把注胶孔14和排气孔也堵上即可，进一步防止液体从埋入式道钉的外壳进入到道钉内。
透明盖板2的下表面还设有凹槽23，LED灯罩9焊接在透明盖板的凹槽23内，LED道钉灯3安装在LED灯罩9内。太阳能板7固定安装在LED道钉灯3的下方，由于固定LED灯罩9、LED道钉灯3和太阳能板7的灌封胶101a、101b为透明的灌封胶，所以太阳能板7能够接收透射进透明盖板2的光线，并将光能转换为电能。电路板4和电池3都安装在太阳能板7的下方，电路板4与LED道钉灯3、太阳能板7和电池8电路连接，电路板4内具有相应的程序，用于控制整个道钉灯内部的运行，电池8用于存储太阳能板7转换得来的电能。电路板4、电池8和太阳能板7都安装在透明盖板2和它的挡板21所围成的区域内，便于制作道钉时的安装、固定和灌胶。
本实施例是以埋入式太阳能道钉为例进行阐述，本申请的一种埋入式道钉，同样适用于其他类型的埋入式道钉，如普通道钉、隧道道钉、有线道钉等，若是有线道钉，在最后一次灌胶时把内部导线从注胶孔或排气孔伸出即可。用灌封胶将这些道钉中发光模块、控制模块或其他功能模块都密封固定在底壳和透明盖板围合成的内置腔室内，均能够获得较高的防水性能和抗压性能。
一种埋入式道钉的制作方法，如图8-图12所示，本实施例以制备上述实施例中的埋入式太阳能道钉为例作详细说明。
S100：安装发光模块；
将LED灯罩9固定在透明盖板2的凹槽23内，然后将功能完好的LED道钉灯3安装在LED灯罩9内。
灯罩的固定方式有很多，可以通过螺栓、螺钉等连接在透明盖板的凹槽内，也可以直接把灯罩焊接在透明盖板的凹槽内，或是采用其他的方式固定，本实施例采用超声波焊接的方式，由于超声波焊接具有焊接强度高、密封性能好等优点，能够更好地固定灯罩，也不会损伤到透明盖板的上下表面，即不会影响光线的吸收和道钉灯光源的发射。
另一种实施方式可以先将LED道钉灯3装入LED灯罩9内，然后再把LED灯罩9固定在透明盖板2的凹槽23内。
S200：第一次灌胶；
首先，倒放透明盖板2，挡板21朝上与透明盖板2形成了容置腔体102。倒放透明盖板2是为了后续的灌胶和安装其他功能模块做准备。
然后进行第一次灌胶，将灌封胶101a倒入容置腔体102内，灌封胶101a需要覆盖住LED道钉灯3的灯泡部分，LED道钉灯3的连接线要露出灌封胶101a，以便后续跟电路板4连接。
另外，为了发光模块的发光部分能够发射光线到道钉外，以及后续太阳能板吸收光线，第一次灌胶的灌封胶101a采用透明胶，在第一次灌胶前，将其配比完成后搅拌均匀，对其进行抽真空排气处理，去除灌封胶101a中存在的气体气泡。此外，在第一次灌胶后以及灌封胶101a固化前，用高温处理道钉的容置腔体102内的气泡，8小时后灌封胶101a完全固化。图8为第一次灌胶后埋入式道钉的剖视图。
S300：安装太阳能板
待第一灌胶的灌封胶101a固化后，将太阳能板7放置于固化后的灌封胶101a上；
S400：第二次灌胶；
进行第二次灌胶，灌封胶101b覆盖住太阳能板7的板体，并且使得太阳能板7和LED道钉灯3的连接线都露出灌封胶101b。
与第一次灌胶一样，第二次灌胶的灌封胶101b同样采用透明的灌封胶，使得LED灯罩9、LED道钉灯3和两层灌封胶(101a、101b)都不会挡住太阳能板7吸收光线，在第二次灌胶之前，将灌封胶101b配比完成后搅拌均匀，对其进行抽真空排气处理。在第二次灌胶后以及灌封胶101b固化前，对道钉的容置腔体102内进行抽真空排气处理，去除第二次灌胶过程中产生的气体和气泡，8小时后灌封胶101b完全固化。图9为第二次灌胶后埋入式道钉的剖视图。
S500：安装控制模块和储能模块；
待第二灌胶的灌封胶101b固化后，将储能模块电池8的正负极连接在电路板4上的相应位置，然后把太阳能板7和LED道钉灯3的连接线也连接在电路板4上的相应位置，并将电路板4和电池8安装在固化后的灌封胶101b上。
在这步骤中，使用控制模块前，把埋入式道钉运行所需要的程序烧录进控制模块电路板4中。电路板4和电池8的安装位置控制在挡板21围成的区域内（即容置腔体），以便安装和后续第三次灌胶能够直接覆盖住挡板21、电路板4、电池8和各连接线。在电路板4和电池8、LED道钉灯3以及太阳能板7均连接完成之后，对埋入式太阳能道钉进行放电和充电测试，查看能否正常使用。
S600：安装底壳；
将底壳1装在透明盖板2上，底壳1的侧板11和透明盖板2的挡板21贴合卡接，底壳1和透明盖板2围合成内置腔室100，以此完成了道钉的外壳安装。
在盖上底壳1之前，把密封圈5放置于底壳1和透明盖板2的连接处，螺钉6穿过透明盖板2边缘的沉头孔22、密封圈5上的孔以及底壳1的螺孔16，将透明盖板2、密封圈5和底壳1依次紧固。图10为安装底壳后的埋入式道钉的剖视图。
S700：第三次灌胶；
进行第三次灌胶，将灌封胶101c从底壳的底板12的注胶孔14注入内置腔室100内部，使得灌封胶101c覆盖住挡板21、电路板4和电池8，以保证道钉内各个模块被灌封胶101c固定住。
在第三次灌胶过程中，灌封胶101c通过注胶孔14注入内置腔室100内时，内置腔室100内的气体通过底壳1的底板12上的排气孔15排出。
第三次灌胶由于不需要考虑LED道钉灯3和太阳能板7的因素，本实施列采用常温固化较快、粘接强度高的白胶，在第三次灌胶之前，将其配比完成后搅拌均匀，并进行抽真空排气处理，当然第三次灌胶也可以采用其他类型的灌封胶，且第三次灌胶可以填充满内置腔室100，使得内置腔室100中的所有的功能模块、连接线以及挡板21和侧板11之间的缝隙均被灌封胶101c所覆盖住。在第三次灌胶后和灌封胶101c固化之前，对整个道钉进行抽真空排气处理，以排除第三次灌胶过程所产生的气体和气泡，8小时后灌封胶101c完全固化。
S800：完成制备。
本实施例是以埋入式太阳能道钉的制作方法为例进行阐述，本申请的埋入式道钉的制作方法同样适用于其他道钉类型，例如针对普通道钉，可以去除安装太阳能板和储能模块等步骤，进行安装发光模块、第一次灌胶、安装控制模块、安装底壳、第二次灌胶等操作步骤，待第二次灌胶固化后，完成普通道钉的制备。针对其它类型的道钉，还可以加入其它功能模块进入内置腔室内。
本申请的一种埋入式道钉，采用杯状结构的底壳和带有挡板的透明盖板作为道钉的外壳，透明盖板的挡板和底壳的侧板贴合卡接，从而围成了内置腔室，内置腔室内充有固化的灌封胶，灌封胶将内置腔室中的发光模块、控制模块等元器件固定，阻止了道钉周围的液体侵入，而且灌封胶固化后，埋入式道钉的内部各个功能模块成为了实心结构，内部没有空隙和气泡，具有较高的密封防水性能，且固化后的灌封胶和底壳一起撑起了透明盖板，在车辆碾压或道路对道钉产生压力时，具有较强的抗压能力。
一种埋入式道钉的制作方法，安装好发光模块，在第一次灌胶前倒放透明盖板，倒放后的透明盖板上的挡板与透明盖板本身形成容置腔体，在容置腔体内进行灌胶、安装相应的功能模块、再灌胶等操作，然后再装上底壳，底壳和整个透明盖板围成内置腔室，通过底壳底板上的注胶孔进行最后一次灌胶，待最后一次灌胶的灌封胶固化后，完成埋入式道钉的制备。
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
