下面结合附图并参考具体实施例描述本公开。
本公开提出的一实施例的中央控制器1000壳体100,如图1至图6所示,本实施例的中央控制器1000壳体100包括:中框110;第一盖体120,扣设在中框110的第一侧,以在第一盖体120、中框110之间形成第一腔体;以及,第二盖体130,扣设在中框110的第二侧,以在第二盖体130、中框110之间形成第二腔体。
在本实施例中,通过中框110与第一盖体120、第二盖体130的组合,将壳体100至少分割为第一腔体和第二腔体,通过第一腔体和第二腔体可以将中央控制器1000的各控制部件至少集成为两个面积较小的电路板,使电路板呈平行地设置在中央控制器1000壳体100内,即减小了单个电路板的面积,可以方便电路板的安装,又可以改善电路板的模态,减少电路板在工作过程中承受各类振动和冲击载荷;同时,电路板平行设置在第一腔体和第二腔体内,能够确保中央控制器1000壳体100的体积较为紧凑,减小壳体100的最大正投影面积,方便中央控制器1000在汽车内的设置。
在其他实施例中,中央控制器1000壳体100可以包括若干依次叠设设置的中框110。例如,在中央控制器1000的壳体100中包括两个叠设的中框110,进而在两个叠设的中框110两侧分别设置第一盖体120和第二盖体130,通过两个中框110将壳体100分割为第一腔体、第二腔体以及位于第一腔体 和第二腔体之间的中央腔体,以使中央控制器1000壳体100内可以设置三个电路板。
作为一种可选实施方式,在本实施例的中央控制器1000壳体100中,如图3和图4所示,本实施例的中框110包括隔板111和围设在隔板111上的侧壁112。
在本实施例中,中框110的隔板111能够将壳体100分割为第一腔体和第二腔体,从而在壳体100内形成两个安装空间供中央控制器1000电路板的设置。在一些实施例中,中框110的隔板111和侧壁112可以用于固定电路板、冷却装置200等结构。
如图3和图4所示,本实施例的隔板111上开设有避让板间连接器的连接器避让区116。
在本实施例中,中央控制器1000壳体100内设有第一腔体和第二腔体,可以在第一腔体和第二腔体内分别设置第一电路板300和第二电路板400,第一电路板300和第二电路板400可以通过板间连接器连接。在隔板111上开设有连接器避让区116,能够使板间连接器顺利穿过中框110分别与第一电路板300和第二电路板400连接。
可选的,板间连接器可以采用3cm的高速板间连接器,实现投影面积小型化的同时也达成了总体>8Gbps的通讯效率。
如图3和图4所示,本实施例的隔板111开设有避让冷却装置200的冷却避让区115。
中央控制器1000的电路板集成有多种芯片,因此电路板的产热量较大,需要设置相应的冷却装置200以对电路板进行散热。可以针对第一电路板300和第二电路板400分别单独设置冷却装置200进行散热。为了使中央控制器1000整体的结构更为简单,优选的在中央控制器1000的壳体100内设置一个冷却装置200同时对第一电路板300和第二电路板400进行散热。在本实施例中,冷却装置200可以设置在中框110的第一侧或第二侧,并可以通过中框110的隔板111上冷却区对中框110另一侧的电路板进行散热。
在本实施例中,中框110的隔板111通过开设连接器避让区116、冷却 避让区115等避让区域实现中框110第一侧和第二侧的连通以方便设置板间连接器和冷却装置200等结构,保留部分隔板111用于固定电路板、冷区装置等结构,并且可以增强中框110的结构强度。
在其他实施例中,中框110也可以仅设置围壁而不设有隔板111,方便板间连接器和冷却装置200的设置,例如,可以在围壁上设有用于固定电路板和冷却装置200的安装部以方便在中央控制器1000壳体100内设置电路板和冷却装置200。
作为一种可选实施方式,如图2所示,本实施例的中央控制器1000壳体100还包括:连接架500,可拆卸地设置在中框110、第一盖体120或第二盖体130上。
在相关技术中,为了适配不同的车型,需要设置不同结构的中央控制器1000壳体100。在本实施例中,通过可拆卸地设置连接架500并通过连接架500将中央控制器1000壳体100固定在汽车中国,能够使中央控制器1000壳体100跨车型应用,针对不同的车型配置不同的连接架500,跨车型应用时只需要更换与车型适配的连接架500即可,降低了中央控制器1000的生产成本,提高了经济效益。
基于同样的公开构思,本公开实施例还提出了一种中央控制器1000,该中央控制器1000包括上述的中央控制器1000壳体100和设置在中央控制器1000壳体100内的第一电路板300、第二电路板400。
因本公开提供的中央控制器1000包括了上述技术方案的中央控制器1000壳体100,因此本公开提供的中央控制器1000具备上述中央控制器1000壳体100的全部有益效果,在此不做赘述。
如图2和图8所示,中央控制器1000还包括:冷却装置200,设置在中框110上,以使冷却装置200的两侧分别与第一电路板300和第二电路板400贴合。
随着中央控制器1000中的电路板的集成度增高,且对高算力AI芯片的需求增加,中央控制器1000对散热的需求也相应增加以避免电器热害。在本实施例中,通过在中央控制器1000的中框110上设置冷却装置200,同时中 框110的隔板111上设有相应的冷却避让区115,从而能够使设置在中框110上的了冷却装置200能够同时对中框110两侧的第一电路板300和第二电路板400进行冷却散热。可选的,在本实施例中,冷却装置200可以通过螺栓等连接件固定在中框110的侧壁112或隔板111上。
如图7至图9所示,冷却装置200包括:冷却板210,包括冷却板本体211和设置在冷却板210体内的冷却流道212;第一散热板220,设置在冷却板210的第一侧,第一散热板220用于贴合第一电路板300;以及,第二散热板230,设置在的冷却板210的第二侧,第二散热板230用于贴合第二电路板400。
上述冷却装置200包括冷却板210、设置在冷却板210第一侧的第一散热板220以及设置在冷却板210第二侧的第二散热板230,通过分体式结构的冷却装置200,即能够通过第一散热板220对第一电路板300进行交换散热,还能够通过第一散热板220将冷却板210与第一电路板300隔绝开,避免设置在冷却板本体211内的冷却流道212泄漏导致第一电路板300的损伤,以保护第一电路板300免受损害。同理,能够通过第二散热板230对第二电路板400进行交换散热,还能够通过第二散热板230将冷却板210与第二电路板400隔绝开,避免设置在冷却板本体211内的冷却流道212泄漏导致第二电路板400的损伤,以保护第一电路板300免受损害。
在一些实施例中,上述冷却装置200可以通过第一散热板220和第二散热板230同时对位于冷却装置200两侧的电路板进行冷却,避免了针对各个电路板需要单独设置冷却装置200,减少了冷却装置200的数量和占用的空间。
在一些实施例中,上述的冷却装置200可以通过更换冷却板210两侧的第一散热板220和第二散热板230的结构以满足不同电路板的散热需求,使冷却板210的适用范围更广,
在一些实施例中,上述的冷却装置200中,冷却流道212中流通有冷却水或制冷剂。
在相关技术中,中央控制器1000可以采用风冷散热,主要以空气对流方式进行散热,空气自然对流换热效率5-25W/㎡*K,需要使用较大的散热翅 片才能满足整车85℃恶劣场景下的散热需求。而在本公开中,可以采用水冷散热,水冷散热的强制对流系数可以达到1000-15000W/㎡*K,因此采用水冷散热既能够避免使用较大的散热翅片,缩小中央控制器1000的整体体积,而且换热效率更高,能够满足整车恶劣环境下的散热需求。
在一些实施例中,如图7至图9所示,设置在冷却板210体内的冷却流道212设有冷却入口和冷却出口,可以从整车介入冷却水路。按照最小流速1L/min,入口水温55℃,出口水温100℃(车规芯片最低结温105℃),例如该冷却板210的换热面积为0.2m2,可以通过公式Q=K水*0.2*45(K水1000-15000W/㎡*K)粗算得出该冷却装置200的换热量为:900W~13500W,考虑实际导热器件导致的传热折损,也可以满足未来中央控制器1000500W的散热需求。
作为一种可选实施方式,如图7至图9所示,本实施例的第一散热板220包括第一散热板本体221,在第一散热板本体221邻近第一电路板300的一侧设有至少一个第一导热凸台222,第一导热凸台222用于贴合在第一电路板300上的发热元件上;和/或,第二散热板230包括第二散热板本体231,在第二散热板本体231邻近第二电路板400的一侧设有至少一个第二导热凸台,第二导热凸台用于贴合在第二电路板400上的发热元件上。
中央控制器1000的电路板采用集成设计,不仅电路板上集成芯片较多,且考虑布板面积等因素则芯片位置不同、高度不同、发热量不同,故而对散热需求也不同。
在本实施例中,冷却装置200可以对电路板进行选点冷却,例如,在对第一散热板220和第二散热板230进行结构实际前,先对第一电路板300和第二电路板400上各芯片、元器件进行热力学参数仿真实验,从而根据仿真结果对第一散热板220和第二散热板230进行结构设计,在第一散热板220上与第一电路板300上的主要发热点对应位置设置相应的第一导热凸台222,同理,在第二散热板230上与第二电路板400上的主要发热点对应位置设置相应的第二导热凸台。以实现通过第一导热凸台222和第二导热凸台分别对第一电路板300和第二电路板400实现定点散热,以提高散热效率。
作为一种可选实施方式,如图7至图9所示,本实施例中冷却流道212在冷却板210内的流经途径至少经过第一导热凸台222和/或第二导热凸台。
在本实施例中,设有第一导热凸台222和第二导热凸台的位置是对散热需求较高的位置,为了进一步提高第一导热凸台222、第二导热凸台与冷却板210的换热效率,使冷却流道212在冷却板210内的流经途径至少经过第一导热凸台222和/或第二导热凸台,从而达到更好的散热效果。相应的,中框110上开设的冷却避让区115能够供第一导热凸台222或第二导热凸台穿设于其中以对电路板进行散热。
作为一种可选实施方式,本实施例的第一导热凸台222与第一电路板300之间设有导热胶层,和/或,第二导热凸台与第二电路板400之间设有导热胶层。
在本实施例中,导热胶层可以采用具有导热功能的散热硅胶能材料制备而成,通过在第一导热凸台222与第一电路板300之间设有导热胶层,和/或,第二导热凸台与第二电路板400之间设有导热胶层,能够实现电路板上各芯片与导热凸台的柔性接触,从而能够避免各芯片与导热凸台刚性接触下由于振动等原因导致芯片损伤。
作为一种可选实施方式,如图7至图9所示,本实施例的第一散热板220与冷却板210对应开设有第一定位孔213,第一散热板220与冷却板210通过第一连接件和第一定位孔213连接;和/或,第二散热板230与冷却板210对应开设有第二定位孔214,第二散热板230与冷却板210通过第二连接件和第二定位孔214连接。
在本实施例中,第一散热板220能够通过第一连接件穿过第一定位孔213实现第一散热板220与冷却板210的固定连接,第二散热板230能够通过第二连接件穿过第二定位孔214实现第二散热板230与冷却板210的固定连接。在某些情况下,第一定位孔213和第二定位孔214可以重叠,即通过一个连接件可以依次穿过第一散热板220、冷却板210以及第二散热板230实现冷却装置200的定位连接。
作为进一步可选的实施方式,本实施例的第一散热板220和/或第二散热 板230通过钎焊固定在冷却板210上。
在本实施例中,可以首先通过定位销将第一散热板220和第二散热板230预先定位在冷却板210上,进而可以通过钎焊将第一散热板220和第二散热板230固定在冷却板210上。通过钎焊可以是第一导热板与水冷板之间密闭连接、第二导热板与水冷板之间密闭连接。通过第一导热板和第二导热板将冷却流道212围设在其中,避免由于加工精度、振动等原因冷却流道212产生的泄漏进入电路板。
作为一种可选的实施方式,本实施例的第一导热凸台222通过钎焊固定在第一散热板220上,第二导热凸台可以通过钎焊固定在第二散热板230上。
在本实施例中,第一散热板220与第一导热凸台222采用分体式设计,第一导热凸台222可以根据散热需求灵活设置在第一散热板220上;第二散热板230同理。以实现在电路板结构变更后可以提供调整散热块实现最大程度的复用模具,降低生产成本。
作为一种可选实施方式,如图2和9所示,冷却装置200可以通过螺接关系整体连接到中框110上。相应的,第一电路板300和第二电路板400也可以通过螺接管理连接到中框110上,以使第一电路板300和第二电路板400固定在中框110上并通过冷却装置200进行散热。
在一些实施例中,中框110上可以设有与冷却装置200对应的装配定位部、与电路板对应的装配定位部,进而使冷却装置200和电路板能够准确装配至中框110上并且使冷却装置200的导热凸台与电路板上的芯片相对应。
作为一种可选实施方式,第一电路板300的两侧分别设有第一电磁屏蔽层;第二电路板400的两侧分别设有第二电磁屏蔽层;中框110的第一侧设有第一中框电磁屏蔽围壁113,中框110的第二侧设有第二中框110电磁屏蔽围壁;第一盖体120的内侧设有第一盖体电磁屏蔽围壁121且扣设在中框110的第一侧,以使第一盖体电磁屏蔽围壁121与第一中框电磁屏蔽围壁113相抵接;以及,第二盖体130的内侧设有第二盖体130电磁屏蔽围壁且扣设在中框110的第二侧,以使第二盖体130电磁屏蔽围壁与第二中框110电磁屏蔽围壁相抵接。
在本实施例中,通过在第一电路板300的两侧分别设有第一电磁屏蔽层;在第二电路板400的两侧分别设有第二电磁屏蔽层,即实现第一电路板300、第二电路板400的板间电磁屏蔽,又实现了向中央控制器1000表面的电磁屏蔽;进一步地,控制控制器的壳体100还设有相互配合的电磁屏蔽围壁,通过电磁屏蔽围壁的配合实现了向中央控制器1000四周的电磁屏蔽,从而实现电路板全屏蔽。即在本实施例中,第一电路板300由第一盖体120、中框110以及第一电路板300本身形成全方位立体的电磁屏蔽,第二电路板400由第二盖体130、中框110以及第二电路板400本身形成全方位立体的电磁屏蔽,通过电路板与壳体100的配合实现电路板间的电磁屏蔽和中央控制器1000向外的电磁屏蔽。
作为一种可选实施方式,在其他实施例中,也可以通过在壳体100上与电路板表面对应壳体100表面设置电磁屏蔽层替代电路板上设置的电磁屏蔽层。例如,第一盖体120的内侧设有第一盖体120电磁屏蔽层,中框110的第一侧设有第一中框110电磁屏蔽层,以替代第一电路板300两侧的第一电磁屏蔽层;同理,第二盖体130的内侧设有第二盖体130电磁屏蔽层,中框110的第二侧设有第二中框110电磁屏蔽层,以替代第二电路板400两侧的第二电磁屏蔽层。
在该实施例中,若第一电路板300和第二电路板400的功率较小,可以不设置冷却装置200,即中框110的隔板111上未开设冷却避让区115,从而能够在中框110的隔板111上形成完整的第一中框110电磁屏蔽层和第二电磁屏蔽层。在该实施例中,若第一电路板300或第二电路板400的功率较大,需要设置冷却装置200,同时需要在中框110的隔板111上开设冷却避让区115,为了使冷却避让区115具有电磁屏蔽功能,故而可以在冷却装置200的冷却板210、第一散热板220以及第二散热板230中的任意一个或几个板体结构上设置电磁屏蔽层替代中框110上的电磁屏蔽层,以实现第一电路板300和第二电路板400间的电磁屏蔽。
针对第一电路板300,第一盖体120电磁屏蔽层、第一盖体电磁屏蔽围壁121、第一中框110电磁屏蔽层以及第一中框电磁屏蔽围壁113形成对第一 电路板300的全包围,故而可以将第一电路板300与第二电路板400以及其他设备进行电磁隔离,实现对第一电路板300的电磁屏蔽。第二电路板400的电磁屏蔽与第一电路板300相同,在此不再赘述。
作为一种可选实施方式,如图3和图10所示,第一中框电磁屏蔽围壁113与第一盖体电磁屏蔽围壁121之间设有第一电磁辐射打断部114;第二中框110电磁屏围壁与第二盖体130电磁屏蔽围壁之间设有第二电磁辐射打断部。
在本实施例中,由于中框110与两块电路板或两个盖体无法做到绝对平行,因此无法做到完整平面屏蔽,为了提高屏蔽效果,本公开通过设置第一电磁辐射打断部114和第二电磁辐射打断部,从而在中框110与第一盖体120之间、中框110与第二盖体130之间形成电磁屏蔽网格结构,使电磁场通过电磁屏蔽网格结构时产生涡流,使电磁场进行内部抵消最终实现电磁屏蔽效果。
作为一种可选实施方式,如图3和图10所示,在本实施例中,相邻的第一电磁辐射打断部114的间距为8cm~12cm;相邻的第二电磁辐射打断部的间距为8cm~12cm。在一些实施例中,相邻的第一电磁辐射打断部114的间距可以为10cm;相邻的第二电磁辐射打断部的间距为10cm。
在本实施例中,经过实验验证,车载器件信号频率一次谐波频率<2GHz根据电磁波屏蔽原理公式:λ截止=2a,其中,a为屏蔽墙孔径。例如当第一电磁辐射打断部114的间距a和第二电磁辐射打断部的间距a均为10cm时,则根据式f=c/λ=c/2a=2.794Ghz,其中,c=3*108m/s。即第一电磁辐射打断部114的间距和第二电磁辐射打断部的间距为10cm时,对电磁波的截止频率为2.794GHz,即小于该频段的对外辐射可以被隔离屏蔽。
作为一种可选实施方式,本实施例的第一电磁辐射打断部114包括设置在中框110第一侧的侧壁112上的金属凸起和/或设置在第一盖体120的侧壁112上的金属凸起;第二电磁辐射打断部包括设置在中框110第二次的侧壁112上的金属凸起和/或设置在第二盖体130的侧壁112上的金属凸起。
在本实施例中,通过在壳体100的各侧壁112上设置金属凸起,通过金 属凸起在壳体100的各侧壁112形成类似金属网格结构,以通过该金属网格结构隔离中央控制器1000的对外电磁辐射。
作为一种可选实施方式,本实施例的第一电路板300的两侧分别设有第一电磁屏蔽层;第二电路板400的两侧分别设有第二电磁屏蔽层。
在本实施例中,通过第一电路板300的两侧分别设置第一电磁屏蔽层,实现对第一电路板300上下表面的对外电磁辐射屏蔽,进而通过第一盖体电磁屏蔽围壁121与第一中框电磁屏蔽围壁113实现对第一电路板300四周对外电磁辐射屏蔽;同理,通过第二电路板400的两侧分别设置第二电磁屏蔽层,实现对第二电路板400上下表面的对外电磁辐射屏蔽,进而通过第二盖体130电磁屏蔽围壁与第二中框110电磁屏蔽围壁实现对第二电路板400四周对外电磁辐射屏蔽。
作为一种可选实施方式,如图12和图13所示,本实施例第一电路板300的边沿设有第一边沿电磁屏蔽线310;第二电路板400的边沿设有第二边沿电磁屏蔽线410。
在一些实施例中,第一边沿电磁屏蔽线310可以与第一盖体电磁屏蔽围壁121或第一中框电磁屏蔽围壁113相抵接;第二边沿电磁屏蔽线410可以与第二盖体130电磁屏蔽围壁或第二中框110电磁屏蔽围壁相抵接。
作为一种可选实施方式,如图2至图4所示,第一电路板300与第二电路板400之间设有板间连接器;相应地,中框110开设有连接器避让区116,中框110的第一侧绕连接器避让区116设有第一连接器电磁屏蔽围壁117,中框110的第二侧绕连接器避让区116设有第二连接器电磁屏蔽围壁118。进一步优选的,第一电路板300、第二电路板400与围绕连接器避让区116对应位置设有连接器电磁屏线。
在本实施例中,为了避免第一电路板300与第二电路板400之前通过连接器避让区116的电磁干扰,故而在中框110绕连接器避让区116设置第一连接器电磁屏蔽围壁117以与位于第一电路板300上的连接器电磁屏线抵接,在中框110绕连接器避让区116设置第二连接器电磁屏蔽围壁118以与位于第二电路板400上的连接器电磁屏线抵接,从而将板间连接器包覆在其中,避 免板间电磁干扰。
作为一种可选实施方式,电磁屏蔽围壁以及电磁屏蔽层由金属材料制备而成。通过金属材料实现电磁屏蔽作用。可选的,金属材料可以为铜。
基于同样的公开构思,本公开实施例还提供了一种汽车,汽车包括上述的中央控制器1000。
因本公开提供的汽车包括了上述技术方案的中央控制器1000,因此本公开提供的汽车具备上述中央控制器1000的全部有益效果,在此不做赘述。
需要说明的是,本公开实施例中所有方向性指示仅用于解释在某一特定姿态下各部件之间的相对位置关系、运动情况等,如果该特定姿态发生改变时,则该方向性指示也相应地随之改变。
另外,在本公开中如涉及“第一”、“第二”等的描述仅用于描述目的,而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者多个所述特征。在本公开的描述中,“多个”的含义是两个或两个以上,除非另有明确具体的限定。
另外,各个实施例之间的技术方案可以相互结合,但是必须是以本领域普通技术人员能够实现为基础,当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在,也不在本公开要求的保护范围之内。
