在实际应用过程中，MVB网关分为多种类型，比如MVB-MVB网关、PCI Express-MVB网关和HDLC-MVB网关等，该多种类型的网关装置可单独设立，也可集合在同一个网关装置中；当上述多种类型的网关集合在同一个网关装置中时，该网关装置需提供多个数据接口，以实现多种协议类型的转换。
现有技术提供了一种直立模块式网关装置，该直立模块式网关装置将数据接口设置在内置电路板的侧身，由于电路的厚度极其有限，若将数据接口设置在电路板的侧身，则网关装置可提供的数据接口的数量较少，从而导致网关装置数据转换效率较低。为了解决现有技术中直立模块式网关装置存在的上述问题，本发明提供了一种MVB网关装置，可提供多个数据接口，提高了数据转换效率。
下面以具体地实施例对本发明的技术方案以及本发明的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本发明的实施例进行描述。
图1为本发明提供的MVB网关装置的实施例一的立体结构示意图，如图1所示，本实施例提供的MVB网关装置，包括：盖板10、第一电路板11、第二电路板12和底板13；所述盖板10与所述底板13围设成一腔体，所述第一电路板11与所述第二电路板12电连接，所述第一电路板11与所述第二电路板12平行固定在所述腔体内，所述第一电路板11的表面设有至少两个接口111，所述盖板10的顶面设有与所述至少两个接口111对应的开孔101，所述至少两个接口111通过所述开孔101与外部设备连接。
可选的，盖板10可以设置为空心的方体结构，该方体结构的一面设为开口，相应的，将底板13设为与盖板10开口一面尺寸匹配的平面结构。或者，底板13可以设置为空心的方体结构，该空心的方体底板13一面设为开口，相应的，将盖板10设为与底板13开口一面尺寸匹配的平面结构。再或者，盖板10设为方体结构，该方体包括一个顶面和两个相对的侧面，相应的，将底板13设为与盖板10尺寸匹配的方体结构，该方体底板13包括一个底面和两个相对的侧面。
需要说明的是，根据上述任意一个方案设置的盖板10和底板13均能围设成一个密闭的方形腔体，用于容纳第一电路板11和第二电路板12。
其中，第一电路板11和第二电路板12与盖板10的顶面或底板13的底面尺寸匹配，以防止第一电路板11和第二电路板12安装时出现固定不稳的情况。第一电路板11和第二电路板12平行设置，第一电路板11设置在靠近盖板10的顶面的一侧，第二电路板12设置在靠近底板13的底面的一侧，第一电路板11与第二电路板12电连接，用于完成该MVB网关装置中数据转换的工作，第一电路板11和第二电路板12进行数据转换的原理和现有技术类似，在此不再赘述。
需要说明的是，在对上述腔体的高度进行设置时，需充分考虑第一电路板11上各接插件的高度，以使第一电路板11上的各接插件可以通过盖板10上的开孔101与外部设备连接。
其中，第一电路板11的表面可设置多个接口111，接口111的具体数量和类型可根据用户的需求自行设定；盖板10上设置与该多个接口111对应的多个开孔101，该多个接口111通过盖板10上的对应开孔101与外部设备连接。比如，参见图1所示，可在第一电路板11上设置4个DB9接口和一个RJ45接口，相应的，盖板10上设置4个DB9开孔和一个RJ45开孔，其中，4个DB9开孔和4个DB9接口的位置一一对应，RJ45接口与RJ45开孔的位置对应。由于本实施例提供的MVB网关装置中数据接口111是设置在第一电路板11的表面，电路板的表面的面积远远大于电路板侧身的面积，使得用户可以在第一电路板11上设置多个接口111，该多个接口111通过盖板10上对应的多个开孔101与外部设备同时连接，大幅度提高了数据转换效率。
本实施例提供的MVB网关装置，通过设置盖板、第一电路板、第二电路板和底板；将盖板与底板围设成一腔体，将第一电路板与第二电路板电连接，将第一电路板与第二电路板平行固定在所述腔体内，在第一电路板的表面设有至少两个接口，在盖板的顶面设置与上述至少两个接口对应的开孔，使得该用户可在第一电路板上设置多个接口，并通过盖板上对应的多个开孔与外部设备同时连接，大幅度提高了数据转换效率。
MVB网关装置各部件之间连接的牢固度与整个MVB网关装置的质量有紧密的联系。图2a为本发明提供的MVB网关装置的实施例二的立体结构示意图，为了提高MVB网关装置中各部件之间连接的牢固度，如图2a所示，在图1所示实施例的基础上，本实施例提供的MVB网关装置，还包括：十字盘头螺钉14、第一单通螺柱15、第二单通螺柱16和铆接螺柱17；所述盖板10通过所述十字盘头螺钉14和所述第一单通螺柱15与所述第一电路板11连接；所述第一电路板11通过所述第一单通螺柱15和所述第二单通螺柱16与所述第二电路板12连接；所述第二电路板12通过所述第二 单通螺柱16与所述铆接螺柱17与所述底板13连接。
参见图2a所示，可在盖板10的4个角上分别设置四个固定孔，在第一电路板11和第二电路板12对应位置也设置4个固定孔；将4个十字盘头螺钉14的螺杆部分旋入盖板10上的4个固定孔中，可选的，为了防止盖板10表面受损，可使用标准型弹簧垫圈和小垫圈配合十字盘头螺钉14使用；4个十字盘头螺钉14的螺杆部分旋入盖板10上的4个固定孔后，再分别旋入4个第一单通螺柱15中设有内螺纹的一端，由此，盖板10便和第一电路板11连接起来；将4个第一单通螺柱15的螺杆部分分别旋入4个第二单通螺柱16中设有内螺纹的一端，由此，第一电路板11和第二电路板12连接起来。
继续参照图2a所示，为了将腔体内的第一电路板11和第二电路板12支撑起来，利于第一电路板11和第二电路板12散热，可在底板13上与上述固定孔对应位置铆接4个螺柱，上述4个第二单通螺柱16的螺杆部分旋入该4个铆接螺柱内，由此，第二电路板12便和底板13连接起来，且底板13上的4个螺柱将第一电路板11和第二电路板12支撑了起来，有利于第一电路板11和第二电路板12散热。
可选的，十字盘头螺钉14的螺杆部分的长度小于第一单通螺柱15设有内螺纹一端的长度，第一单通螺柱15螺杆部分的长度小于第二单通螺柱16设有内螺纹一端的长度，第二单通螺柱16螺杆部分的长度小于底板13上铆接的螺柱的长度，以使上述部件之间可以稳固连接，提高各部件之间连接的牢固度。
在MVB网关装置安装过程中，盖板10可能会出现左右晃动的情况，给安装人员带来不便，降低了安装效率。图2b为本发明提供的MVB网关装置实施例二的另一立体结构示意图，为了解决盖板10出现左右晃动的问题，本实施例提供的MVB网关装置，还包括：至少两个凸起102和至少两个凹槽131，所述至少两个凸起102对称设置在所述盖板10两个侧面的底部；所述至少两个凹槽131与所述至少两个凸起102数目相同，所述至少两个凹槽131设置在所述底板13的底面上，所述至少两个凸起102与所述至少两个凹槽131一一对应连接。
其中，凸起102的具体数量可根据用户需求自行设定，凹槽131的数量与凸起102的数量相同；比如，凸起102的数量可设置为8个，其中4个均匀设置在盖板10一个侧面的底端，另外4个均匀设置在盖板10另一个侧面的底端，8个凹槽131的位置与上述8个凸起102的位置对应；当用户需要安装上述MVB网关装置时，可按以下步骤进行安装：第一步、通过铆接螺柱17和第二单通螺柱16将第二电路板12和底板13进行连接；第二步、通过第一单通螺柱15和第二单通螺柱16将第一电路板11和第二电路板12进行连接；第三步、将盖板10上的凸起102和底板13上的凹槽131匹配连接；第四步、通过十字盘头螺钉14和第一单通螺柱15将盖板10和第一电路板11进行连接。上述安装过程中，将盖板10上的凸起102和底板13上的凹槽131匹配连接后再将盖板10与第一电路板11连接，防止了盖板10的左右晃动给安装过程带来的不便。
本实施例提供的MVB网关装置，其实现原理和技术效果与实施例一类型，在实施例一的基础上，通过设置十字盘头螺钉、第一单通螺柱、第二单通螺柱和铆接螺柱；将盖板通过十字盘头螺钉和第一单通螺柱与第一电路板进行连接；将第一电路 板通过第一单通螺柱和第二单通螺柱与第二电路板进行连接；将第二电路板通过第二单通螺柱与铆接螺柱与底板进行连接，提高了MVB网关装置各部件之间连接的牢固度。同时，通过设置至少两个凸起和至少两个凹槽，将该至少两个凸起对称设置在盖板两个侧面的底部；至少两个凹槽与所述至少两个凸起数目相同，将至少两个凹槽设置在底板的底面上；使得在MVB网关装置安装过程中，可将盖板上的凸起和底板上的凹槽匹配连接后再将盖板与第一电路板连接，防止了盖板的左右晃动给安装过程带来的不便。
图3a为本发明提供的MVB网关装置的实施例三的结构示意图，为了固定第一电路板11上的接口，如图3a所示，在图2b所示实施例的基础上，本实施例提供的MVB网关装置，还包括压铆螺母103和连接孔112；所述压铆螺母103设置在所述开孔101的两端，所述连接孔112设置在所述接口111的两端，所述压铆螺母103和连接孔112用于固定所述至少两个接口111。
其中，压铆螺母103设置在盖板10上每个开孔101的两端，连接孔112设置在第一电路板11上每个接口111的两端，压铆螺母103的数量和连接孔112的数量相同，压铆螺母103的位置和连接孔112的位置对应。将MVB网关装置安装完成后，可选的，可使用螺钉将压铆螺母103和连接孔112连接起来，从而将接口111处的第一电路板11和盖板10更加牢固地连接起来，更加便于接口111与外部设备进行连接。
MVB网关装置在工作过程中，第一电路板11和第二电路板12不可避免会产生热量，MVB网关装置的散热功能与MVB网关装置高效工作有紧密联系。图3b为本发明提供的MVB网关装置实施例三的另一结构示意图，如图3b所示，在图2b所示实施例的基础上，本实施例提供的MVB网关装置，还包括：散热孔104，所述散热孔104设置在所述盖板10的两个侧面上。
其中，散热孔104可设置在盖板10的侧面或者底板13的侧面，散热孔104的形状可设置为圆形或方形，本实施例在此不做限定。
第一电路板11上可设置指示灯，用于指示第一电路板11和第二电路板12工作状态或第一电路板11上各接口111的工作状态；由于第一电路板11设置在高板和底板13围设成的腔体内，因此能够从MVB网关装置外侧观察指示灯亮灭情况尤其重要；为了解决该技术问题，本实施例提供的MVB网关装置，还包括：指示灯开孔105，所述指示灯开孔105设置在所述盖板10的顶面，所述指示灯开孔105与所述第一电路板11上的指示灯位置对应，用于观察所述指示灯的亮灭情况。
其中，指示灯开孔105的尺寸和指示灯的尺寸匹配，用户可通过指示灯开孔105观察第一电路板11上指示灯的亮灭情况，进而判断第一电路板11、第二电路板12和第一电路板11上各接口111等的工作情况是否正常，提高了用户的工作效率。
对用户来说，由于盖板10朝向用户时的工作效率比盖板10朝上时的工作效率要高。图3c为本发明提供的MVB网关装置实施例三的又一结构示意图，为了将上述MVB网关装置的盖板10朝向用户放置，且和车辆的机箱集合为一个整体，在上述实施例的基础上，本实施例提供的MVB网关装置还包括U形孔132，所述U形孔132设置在所述底板13的底面上，用于将所述MVB网关装置固定在机箱上。
需要说明的是，在机箱的对应位置需要设置与上述U形孔132数量相同且结构匹 配的部件，以使上述MVB网关装置可以和机箱牢固地连接起来。
参见图3c所示，U形孔132设置在底板13的底面上，U形孔132的数量可以根据用户需求自行设定；上述MVB网关装置通过U形孔132与机箱连接后，使得MVB网关装置和机箱集合为一个整体，节省了空间，而且MVB网关装置中的盖板10朝向用户设置，提高了用户工作效率。
由于上述盖板10上设置有不同功能的开孔101，为了使用户不混淆上述开孔101的用途，本实施例提供的MVB网关装置，还包括：标识，所述标识设置在所述开孔101的旁边，用于指示所述开孔101的用途，可选的，该标识可为丝印标识。该标识可以使用户清楚地获知每个开孔101的功能，进一步提高了用户的工作效率。
本实施例提供的MVB网关装置，其实现原理和技术效果与实施例二类似，在实施例二的基础上，通过设置压铆螺母和连接孔，将压铆螺母设置在盖板上开孔的两端，将连接孔设置在第一电路板上接口的两端，使得第一电路板上的接口与外部设备连接更加牢固。同时，通过在盖板的两个侧面上设置散热孔，更加便于第一电路板和第二电路板进行散热，提高了MVB网关装置工作效率。同时，通过在盖板的顶面设置指示灯开孔，使得用户可通过指示灯开孔观察第一电路板上指示灯的亮灭情况，进而判断第一电路板、第二电路板和第一电路板上各接口等的工作情况是否正常，提高了用户的工作效率。同时，通过在盖板上各开孔的旁边设置标识，可以使用户清楚地获知每个开孔的功能，进一步提高了用户的工作效率。
