第一方面，本申请提供了一种扩展组件，该扩展组件可以应用于摄像机中。扩展组件包括壳体、背板和扩展板；壳体具有容纳腔，背板设置于容纳腔中；壳体上还设有与容纳腔连通的插孔，扩展板包括板体、第一连接器和第一密封件；板体插设于插孔内，且第一连接器与背板连接，第一密封件将插孔封堵，以使扩展板插接在壳体上时，容纳腔内部为密闭的空间。在本申请提供的扩展组件中，扩展板通过插孔可拆卸地安装于壳体上，当需要调整扩展板的功能时，可以将原有的扩展板拔出，将具有新功能的扩展板插入壳体与背板连接。在实际应用时，可以在出厂前将所需的扩展板安装在扩展组件中，也可以在工程现场将所需的扩展板插接在扩展组件中，从而具有较大的灵活性，不会造成功能不全或功能冗余等不良问题。
在具体实施时，为了保证扩展板安装于壳体时的稳定性，在板体上设有安装部，安装部与壳体固定连接。具体来说，安装部可以为固定面板，固定面板与壳体之间连接的方式有多种，例如：在固定面板上设有第一连接孔，在壳体上设有第二连接孔，且第一连接孔和第二连接孔相对应，紧固件(如螺栓)穿过第一连接孔和第二连接孔将固定面板与壳体连接；或在固定面板朝向壳体的一侧设有卡扣，在壳体上设有开口，卡扣穿过开口将固定面板固定。在固定面板固定设置于壳体的过程中，第一密封件(如密封圈)套设于板体，且第一密封件位于壳体与固定面板之间，以用于将插口密封。
另外，为了便于扩展板与背板匹配，在板体上设有第一连接器，在背板上设有第二连接器(连接器或金手指)，第二连接器与第一连接器连接；且板体为PCB单板。
在具体实施时，为了提高扩展组件的扩展能力，可以将插孔和扩展板均设置为多个。具体来说，多个插孔可以与多个扩展一一对应设置，每个扩展板可以具有不同的功能，在需要对扩展板功能进行调整时，将多个扩展板中的一个或几个拆卸，将具有新的功能的扩展板插设于壳体。或者，插孔的数量大于扩展板的数量，多余的插孔与辅助面板配合(插孔的数量为扩展板与辅助面板的数量之和)，辅助面板能够插设于插孔，且可以封堵插孔，在需要增加扩展组件的功能时，可以直接将辅助面板拆卸，并将具有新的功能的扩展板插接于原辅助面板的位置，不仅可以提高对扩展组件功能的调整，也不会造成功能不全或功能冗余等不良问题。
另外，在具体实施时，壳体可以是一体的结构件，也可以是由多个部件组装而成。
例如：壳体可以包括内壳和外壳。外壳套设在内壳的外周，内壳和外壳围成有用于容纳背板的容纳腔，其中，内壳的内周形成散热通道，当散热通道中气体通过时，可以对设置于容纳腔中的背板及与背板配合的扩展进行散热。另外，内壳可以是管状结构，外壳可以与内壳的形状形同，也可以使其他的规则形状或不规则的形状。
在具体实施时，背板设置于容纳腔中的形式可以为多种，例如：背板套设于内壳的外周(内壳穿过背板)，相应的，扩展板可以绕内壳的周向设置于背板上，以提高散热通道对扩展板的散热效率。或，背板设置于内壳的外壁与外壳的内壁之间，相应的，扩展板可以沿着该外壁至该内壁的方向，均匀间隔分设置于背板上。
在具体实施时所述外壳包括上盖和底座，所述内壳位于底座和上盖围成的空间中；为了保证容纳腔的密闭性，上盖与底座连接的部分可以设置有第二密封件(密封圈)或涂抹密封胶等。
在实际应用时，当扩展板为无限通信扩展板(包括雷达、WiFi组件、4G通信组件)时，为了防止外壳对该扩展板产生屏蔽作用，外壳(上盖)可以由聚碳酸酯、ABS塑料(包括丙烯腈、丁二烯、苯乙烯的共聚物)等非电磁屏蔽材料制成，以保证扩展板的正常工作。
另外，为了提高扩展组件的散热能力，在一些实施方式中，散热通道中还设有风机，风机可以固定安装于散热风道内或者其他位置，以提升流经散热风道的气流的流动速度，进而提升扩展组件的散热能力。
在具体实施时，扩展组件内还可以设有一个或多个高功率单板(具有CPU的单板)，一个或多个高功率单板可以在出厂前将所需的高功率单板加装在扩展组件中，也可以在工程现场将所需的高功率单板加装在扩展组件中。在具体加装高功率单板时，高功率单板设置于容纳腔并与内壳热接触，从而通过散热通道中的气流来对高功率单板进行散热。另外，高功率单板可以为雷达、WiFi组件、4G通信组件、5G通信组件、蓝牙组件等通信电路。也可以是：图形处理器、Ai处理芯片、存储器等器件。
另外，扩展组件可能会应用于室外的环境中，为了提高扩展组件的使用效果，防止因外壳受到阳光等暴晒而产生温度过高的不良情况产生，扩展组件还包括遮蔽罩，遮蔽罩设置于壳体的顶部和外周，以对壳体起保护的作用。另外，遮蔽罩的顶部设有通风孔，流经散热风道的气流也可以通过遮蔽罩的通风孔排出；因此，遮蔽罩不会对内壳的散热风道起到阻碍的作用，进而不会影响到扩展组件的散热性能。
本申请还提供了一种电子设备，该电子设备包括连接组件和主设备组件连接组件用于将主设备组件和扩展组件连接。具体设置时，由于扩展组件独立于主设备组件，在需要调整主设备组件的功能时，可以直接调整扩展组件的功能即可实现，进而提高了电子设备的 适用性。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请提供的扩展组件可以应用在摄像机、室外基站等主设备组件中，以扩展、提升对应主设备组件的功能性。以摄像机为例，目前的摄像机由原来的只是简单的记录画面，逐渐的发展为能够对画面进行实时分析，如：进行人脸识别及车牌识别等。而随着摄像机功能不断的增加，摄像机内部的功能组件也会增加，而摄像机具有的功能一般在出厂前就已经预先的设定完成，且由于有镜头组件的原因，摄像机内部需要进行密封，如果用户在使用过程中需要对摄像机的功能进行更改，或者是需要增加新的功能时，因摄像机的功能在出厂前就已经预先的设定，对于部分用户来说，会导致功能不全或功能冗余等不良情况。另外，一些摄像机中包括有扩展组件，在对摄像机的功能进行扩展或调整时，需要将扩展组件的壳体进行拆卸，然后在替换高功率单板。可以理解的是，上述仅以摄像机为例进行了简单说明，然而在实际应用时，室外基站(如用于收发无线信号的基站)等主设备组件在加装高功率单板时，也面临与上述摄像机相同或类似的技术问题。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、 “一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
请参照图1，在本申请提供的一个实施例中，扩展组件包括：壳体10、背板20和扩展板30，壳体10内具有容纳腔(图中未示出)，背板20设置在该容纳腔中，且壳体10上设有与容纳腔连通的插孔11，扩展板30可以穿过插孔11与背板20之间可拆卸连接。由于扩展组件为独立的组件，当扩展组件加装在摄像机上，且摄像机存在不同的功能需求时，将所需的扩展板30通过插孔11直接安装于背板20；或将原有的一个或多个扩展板30拆卸，更换为所需的扩展板30即可，以调整扩展组件的功能。在实际应用时，扩展板30可以在出厂前安装于扩展组件中，也可以是在现场根据实际的需要安装对应功能的扩展板30，且扩展板30在安装于扩展组件中时，并不需要对扩展组件及摄像机进行拆装，从而具有较大的灵活性，不会造成功能不全或功能冗余等不良问题。另外，扩展板30在安装于扩展组件时，扩展板30与扩展组件上的壳体10之间密封连接，可以防止水汽、灰尘等杂质进入到容纳腔中，提高背板20及扩展板30工作的稳定性。
其中，当扩展板30需要依靠无线信号与外界进行信号传输时(如扩展板30中包含WiFi组件、4G通信组件等)，为了防止壳体10对扩展板30产生屏蔽的作用，壳体10可以由聚碳酸酯、ABS塑料(包括丙烯腈、丁二烯、苯乙烯的共聚物)等非电磁屏蔽材料制成，以保证扩展板30的正常工作。
请参照图2和图3，扩展板可以包括：板体31、第一连接器32和第一密封件33。第一连接器32安装于板体31的一端，第一连接器32用于和背板(图中未示出)上设置的第二连接器配合，以实现扩展板和背板之间的电连接。第一密封件33能够将板体31与插孔进行密封，以使扩展板安装在壳体10上时，并不会影响壳体10的密闭性。另外，为了提高扩展板安装于壳体10上的稳定性，在板体31上设有安装部，安装部用于与壳体10的连接。
在具体配置时，第一连接器32和背板上的第二连接器连接，以便于实现扩展板和背板之间的快速连接。
另外，在具体配置时，第一密封件33可以为密封圈或垫片等，本申请对此不作限定。
在具体配置时，安装部的结构形式可以为多种，例如：安装部配置为固定面板34，固定面板34设置在板体31上远离第一连接器32的一端，并在固定面板34上设有第一连接孔341，在壳体上设有第二连接孔，紧固件35(紧固螺钉)穿过第一连接孔341和第二连接孔与壳体10上的螺母连接，以将安装部与壳体10固定连接。而具体设置第一连接孔341和第二连接孔时，第一连接孔341可以沿固定面板34的延伸方向间隔设置，且第一连接孔341中的部分与第二连接孔对应即可；第一连接孔341和第二连接孔可以均为螺纹孔，也可至少一个为螺纹孔。或，安装部包括固定面板34，在固定面板34朝向壳体的一面设有卡扣(凸出部)，在壳体上设有与卡扣对应的开口，卡扣穿过开口将固定面板固定于壳 体上。
需要说明的是，为了使固定面板34与板体31之间连接的更加便捷，可以在固定面板34下方设置有连接板，连接板垂直于固定面板34，即固定面板34和连接板组成的结构的截面可以呈T形，板体31远离第一连接器32的一端通过螺钉或粘接等方式与连接板连接。
其中，固定面板34与连接板之间连接的方式可以有多种，例如：固定面板34与连接板之间可以为一体构件，二者也可是可拆卸的连接，具体的可拆卸的方式此处不进行列举。另外，固定面板34与连接板之间的也可呈锐角设置，只要是保证扩展板能够与背板连接即可。
请参照图4，在具体实施时，为了提高扩展组件的散热能力，扩展组件(壳体)内还可以设有散热通道131。具体而言，散热通道131中的气流可以将容纳腔中产生的热量快速的带走，以对容纳腔进行散热。其中，热散通道131形成的方式可以多种，如：壳体包括内壳13和外壳12。外壳12套设在内壳13的外周，内壳13的内周即形成上述的散热通道131，内壳13的外周和外壳12围成有用于容纳背板20及扩展板30的容纳腔。或，可以理解的是，扩展组件还包括一个通风管道，通风管道穿过壳体，且通风管道与壳体连接处位密封连接，该通风管道即可形成上述的散热通道。
其中，散热通道131的结构可以为多样。如：散热通道131的截面可以为矩形、圆形或其他的多边形结构。散热通道131可以为直线型、曲线型或折线型。
在具体实施时，为了提高散热通道131的散热能力，内壳13可以由导热性能较强(如铝、铝合金)的材质制备。另外，在内壳13(散热通道)的内壁上也可以设置散热鳍片、散热器、导热管等结构，以提升内壳的散热性。
请参照图5和图6，在一些实施例中，为了提高扩展组件的功能性，在扩展组件中还可以设有一个或多个高功率单板50，高功率单板50与背板20连接。一个或多个高功率单板50设置于容纳腔中，由于，高功率单板50一般的功率较大，因此，高功率单板50中的发热元件通过导热缓冲材料(导热垫或导热硅等。)与内壳13进行热接触，通过散热通道131中的气流来对高功率单板50进行散热。以使扩展组件在增加了功能的同时，还能够保证散热能力。另外，当高功率单板50与内壳13热接触时，背板20也可以套设于内壳13的外部，此时，外壳12上的插孔11及背板20上的第二连接器21均绕内壳13的周向分布，且第二连接器21与插孔11对应设置，以使扩展板30可以设置于高功率单板50与外壳12之间，且，沿同一方向，多个扩展板30也可以间隔分布。具体来说，当扩展组件加装在摄像机上时，扩展组件需要与摄像机摄像组件相互连接，此时，壳体上设有一个电缆通道，第一连接电缆的一端通过电缆通道与背板20连接，第二连接电缆与摄像组件连接，第一连接电缆和第二连接电缆相互对接，以使扩展组件与摄像组件连接，以实现对摄像机的功能扩展。由于，扩展组件为独立的组件，在安装高功率单板时，并不会对摄像机产生影响，且可以在出厂后对高功率单板进行更换，以使其具有较大的灵活性。
另外，继续请参照图5，在一些实施例中，扩展组件中还可以设置风机132。例如，可以将风机132固定安装在散热通道131内或者其他位置，以提升流经散热通道131的气流的流动速度，进而提升扩展组件的散热能力。在具体实施时，风机132可以选择防水、防尘、防震等性能较强的类型，以提升散风机132的可靠性和稳定性。
继续请参照图5-图7，在具体实施时，内壳13和外壳12之间密封连接的方式也可为多种。为了实现内壳和外壳13之间的密封连接，外壳可以包括底座122和上盖121，内壳 13设置于底座122和上盖121围成的空间中。具体来说，上盖121与底座122之间可以通过第二密封件123(密封圈)或涂抹密封胶的方式连接。内壳13具有与上盖121连接的第一端和与底座122连接的第二端，上盖121与底座122上均设有与内壳13中形成的散热通道131相连通的通孔，内壳13可以与上盖朝向底座122的一侧及底座朝向上盖121的一侧通过涂抹密封胶或焊接方式连接，或者，内壳13的外侧壁与上盖121及底座122上通孔的内壁通过涂抹密封胶或焊接方式连接。
请参照图8，内壳12位于外壳13的一侧，内壳12靠近外壳13的一侧与外壳重合(该部分为呈一体设置)，散热通道位于边缘位置。在实际应用时扩展组件可能会应用于户外等较为恶劣的环境中，为了保证扩展组件工作的稳定性，扩展组件可以包括遮蔽罩60。遮蔽罩60可以罩设在外壳13的外周和顶部，并在遮蔽罩的顶部设置有与散热通道连通的通风孔，以使流经散热通道的气流可以通过通风孔流出。这样，遮蔽罩60在对外壳13起到保护时，并不会影响扩展组件中扩展板30及高功率单板50的散热。为了防止灰尘、树叶等异物进入散热通道中，可以在遮蔽罩60的顶部设置有遮蔽板，且遮蔽板61的外轮廓大于通风孔的孔径。或者，通风孔可以设置于遮蔽罩60顶部的侧面，且通风孔与散热通道之间形成有曲线型或拐角的结构，进而可以减少雨水通过通风孔进入到散热通道中。其中，遮蔽板与遮蔽罩60可以采用注塑成型等工艺进行成型为一体结构。或者是遮蔽板61和遮蔽罩60先通过注塑成型等工艺分别制作，然后再通过粘接或螺钉连接的方式连接。而在具体实施时，遮蔽罩60和遮蔽板可以采用聚碳酸酯、ABS塑料(包括丙烯腈、丁二烯、苯乙烯的共聚物)等非电磁屏蔽材料制成，从而不会对扩展板及高功率单板产生电磁屏蔽作用。
请继续参照图9，在一些实施例中，为了保证扩展组件的扩展能力，插孔(图中未示出)和扩展板30的数量均可设置为多个。具体来说，每个插孔上均插设有一个扩展板30，且每个扩展板30所具有的功能可以不同，且在需要对扩展组件进行功能调整时，将部分的扩展板30进行拆卸，更换为具有所需功能的扩展板30即可，而在实际应用的过程中，安装于背板20上的扩展板30可以在出厂前进行安装，也可在工程现场进行安装或对部分扩展板30进行更换，从而使扩展组件具有较大的灵活性，不会造成功能不全或功能冗余等不良问题。请继续参照图10，在一些实施方式中，还包括辅助面板40，此时，插孔的数量为扩展板30的数量与辅助面板40的数量之和，辅助面板40通过可拆卸的方式将壳体10上多余的插孔11封堵，以保证壳体10的密闭性；辅助面板40具体将多个的插孔11封堵的方式可以为，在辅助面板40与壳体10之间设有密封圈，在两个紧固螺钉将辅助面板40固定在壳体10上时，密封圈位于两个紧固螺钉之间；在需要增加扩展组件的功能时，将辅助面板40拆卸、将具有新功能的扩展板30插接于背板20上，从而提高扩展组件的扩展能力，且在扩展的过程中，并不需要将扩展组件的主体进行拆卸，以提高扩展的便捷性。
请继续参照图11，在另一些实施例，散热通道131在容纳腔124中的位置可以为多种，例如：散热通道131设置在容纳腔124中的一侧，此时，将背板20设置在容纳腔124的另一侧，多个扩展板30可以呈阵列分布于背板20。继续请参照图12，当散热通道131设置于内壳13和外壳12形成的容纳腔124的中心位置时，背板20可以套设于内壳13，部分安装于背板20上的扩展板30可以围设在内壳13的周围，以使扩展板30上产生的热量能够快速的被形成与内壳13内周的散热通道131带走，提高散热的效率。
图13中壳体10与连接组件70连接，图14中遮蔽罩60与连接组件连接，请参照图13和图14，本申请还提供了一种电子设备，该电子设备包括连接组件70和主设备组件80，连接组件70用于将主设备组件80和扩展组件连接。具体来说，主设备组件80可以为摄像组件，连接组件70可以为支架，支架可以将摄像组件固定在墙体或道路监控杆上。摄像组件固定安装在支架的下方，摄像组件与支架之间具有一定的安装间隙(即主设备外壳和支架之间具有的安装间隙)，扩展组件可安装于支架的上方，外界的冷风可以通过安装间隙，进而可以带走摄像组件中的产生的热量，以提高电子设备的散热能力。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
