第一端盖1、第一本体2、第二本体3以及第二端盖4配合形成保险盒结构，其中第一端盖1、第一本体2、第二本体3以及第二端盖4由上至下依次排列，且第一端盖1与第一本体2通过卡接的方式连接，第一本体2与第二本体3通过卡接的方式连接，第二本体3与第二端盖4通过卡接的方式连接。其中卡接的连接方式，保证了保险盒结构的牢固性，同时也可以便于保险盒结构的拆卸以及维修。
在第一端盖1与第一本体2之间设置有密封结构，在第一本体2与第二本体3之间设置有密封结构，在第二本体3与第二端盖4之间设置有密封结构，通过设置密封结构，可以使得保险盒结构具有良好的防水性能，进而满足电动汽车整车涉水的需求。
在本公开的实施例中，如图1和图3所示，第一端盖1为一端开口的第一盒体。第一盒体的侧面设置至少一个第一卡接结构13，并通过第一卡接结构13与第一本体2卡接。第一盒体的相邻两侧面上设置有第一导线槽14。
第一端盖1形成的一端开口的第一盒体包括第一板体11，与第一板体11一体成型的第一安装板12，其中第一安装板12设置于第一板体11的周缘且与第一板体11垂直，在第一安装板12上集成有至少一个第一卡接结构13，其中第一卡接结构13的数量可以根据需求来设定，由于第一安装板12包括与第一板体11垂直的四个端面，可以在每一端面上都设置一个第一卡接结构13，来保证保险盒结构的连接牢固性。
在第一安装板12的相邻两侧面上形成有第一导线槽14，其中第一导线槽14的长度大于第一安装板12的高度，且第一导线槽14与第一安装板12一体成型，通过设置第一导线槽14，可以对外部线束的走线方向进行导向。第一导线槽14的延伸方向与第一安装板12的延伸方向相同，可以使得位于保险盒结构外的外部线束走线方向与第一安装板12的延伸方向相同。其中第一导线槽14与第一安装板12配合形成容纳外部线束的空间，同时第一导线槽14对外部线束进行导向。
在本公开的实施例中，如图1、图2、图4以及图9所示，第一本体2为两端开口、中部设置有连接板21的第二盒体。连接板21的第一端面设置有固定电路器件的第一安装结构，连接板21的第二端面设置有固定电路板的第二安装结构。第二盒体的侧面设置有与第一卡接结构13匹配的第一卡槽23，第一卡接结构13与第一卡槽23之间设置有密封条7。第二盒体的侧面上设置有至少一个第二卡槽24。第二盒体的侧面具有容纳外部线束的第二导线槽25，第二导线槽25与第一导线槽14配合。

由于第一端盖1与第一本体2通过卡接的方式连接，在卡接结构形成的缝隙内容易进水，为了防止进水，在第一卡槽23内设置密封条7，使得第一卡接结构13与第一卡槽23过盈配合实现密封的效果，保证保险盒结构的防水性能。
在第二安装板22上设置的第二卡槽24的数量也可根据需求来设定，可以与第一卡槽23的数量相同，也可以不同，本领域技术人员可自行设定。

第三板体31上形成与电路板上的元件匹配的安装槽35，且安装槽35位于第二容置空间内，在第二安装板22与第三安装板32对位接触匹配时，电路板上的元件与安装槽35进行匹配，实现电路板与第三板体31和连接板21的连接。安装槽35与内部线束连接，且与安装槽35连接的内部线束位于第二本体3与第二端盖4形成的空间内。
其中，第一本体2与第二本体3通过卡接的方式连接，在卡接结构形成的缝隙内容易进水，为了防止进水，在第二卡槽24内设置密封条7，使得第二卡接结构33与第二卡槽24过盈配合实现密封的效果，保证保险盒结构的 防水性能。
在第三安装板32上设置的第三卡接结构34的数量也可根据需求来设定，可以与第二卡接结构33的数量相同，也可以不同，本领域技术人员可自行设定。
第三盒体的侧面形成第三导线槽37，第一导线槽14、第二导线槽25以及第三导线槽37配合，形成线束路径。具体为：在第二本体3与第一本体2配合、第一本体2与第一端盖1之后，第三导线槽37与第二导线槽25配合、第二导线槽25与第一导线槽14配合，形成线束路径，实现对外部线束的走向进行导向。其中，第三盒体上同时设置有至少一个弧形结构36，且弧形结构36集成于第三安装板32上。
在本公开的实施例中，如图6以及图9所示，第二端盖4形成一端开口的第四盒体。第四盒体的侧面形成有至少一个线束孔5，与安装槽35连接的内部线束通过线束孔5导出保险盒结构。
