Description

一种电子设备和车辆
本申请要求于2020年12月17日提交到国家知识产权局、申请号为202011492038.7、发明名称为“一种电子设备和车辆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及一种防水防尘结构，尤其涉及一种具有防水能力的电子设备和车辆。
背景技术
自动驾驶车辆的控制系统，尤其是高等级的自动驾驶车辆的控制系统一般包括车载计算模块(或自动驾驶计算平台)，例如移动数据中心(mobile data center，MDC)。车载计算模块能够通过摄像机、激光雷达、毫米波雷达、超声波等车载传感器来感知周围的环境，依据所获取的信息进行决策判断，由适当的工作模型来制定相应的策略，如预测本车与其他车辆、行人等在未来一段时间内的运动状态，并进行避免碰撞路径规划。
随着自动驾驶技术的进步，车辆的自动驾驶等级不断提高，车载计算模块需要实现的功能越来越多，所需的算力也越来越大，结构越来越复杂，尺寸也越来越大。由于车辆中控台空间有限，大尺寸的计算模块只能安装在乘客舱的作为下方或者发动机的前舱内，工作环境相对恶劣，因此要求车载计算模块的整机防水等级要达到IPX7以上。
在高等级的自动驾驶车辆中，各传感器与车载计算模块之间的通信速率和带宽需求越来越高，低速连接器已经无法满足传感器与车载计算模块之间的通信需求，因此高等级自动驾驶车辆的车载计算模块需要配备高速连接器。对于高速连接器与车载计算模块壳体之间、以及高速连接器公头端子和母头端子之间的满足IPX7等级的防水设计，目前尚无成熟的实现方案。
发明内容
本申请实施例提供了一种电子设备和车辆，以解决配备高速连接器的车载计算模块等电子设备的防水问题。
第一方面，本申请实施例提供了一种电子设备，包括：壳体和设备主板；所述壳体包括第一腔室和第二腔室，所述第一腔室和所述第二腔室相邻设置；所述设备主板设置于第一腔室内，所述设备主板设置有连接器，所述连接器用于与外部线缆连接的一端从所述第一腔室延伸到所述第二腔室内；所述壳体包括第二腔室边框和护盖，所述护盖用于扣合在所述第二腔室边框之上；所述第二腔室边框面设置有第一密封胶条；所述护盖包括护盖边框，所述护盖边框设置有第二密封胶条；所述第一密封胶条和所述第二密封胶条对接形成用于外部线缆从所述第二腔室内引出的线缆通道；当所述护盖扣合时，所述第二腔室边框和所述护盖边框压紧所述第一密封胶条，实现所述第二腔室边框与所述护盖边框之间的防水密封，所述第一密封胶条和所述第二密封胶条压紧所述线缆通道内的外部线缆，实现外部线缆与所述第二腔室边框和所述护盖边框之间的防水密封。
本申请实施例提供的电子设备，壳体上设置有可开启和扣合的护盖，该电子设备将 不具备防水性能的连接器设置于壳体内部，外部线缆在壳体内部与连接器连接，然后从壳体内引入到壳体外。为便于线缆引出，壳体与护盖的扣合面具有至少一个线缆通道，并且出线口周围还设置了第一密封胶条和第二密封胶条等壳体密封部件。当护盖扣合时，壳体和护盖能够压紧第一密封胶条，在壳体和护盖之间形成密封，同时，第一密封胶条和第二密封胶条能够压紧线缆，在线缆与壳体和护盖之间形成密封，这样壳体外部的液体和灰尘等不会进入到壳体内部，使得电子设备在使用不具备防水性能的连接器时也能具备防水防尘能力。
在一种可选择的实现方式中，第二腔室边框包括面向所述护盖的第一边框顶面，所述第一边框顶面设置有第一凹槽和第二凹槽，所述第一凹槽围绕所述第二腔室呈环形设置，所述第二凹槽设置在所述第一凹槽的路径上，与所述第二凹槽连通。这样，第一凹槽和第二凹槽在第一边框顶面形成了连续封闭的环形结构，可以设置连续封闭的第一密封胶条，以利于壳体边框与护盖之间的密封。
在一种可选择的实现方式中，第一密封胶条为环形结构，包括第一线缆密封部，所述第一线缆密封部与所述第二凹槽的结构相匹配，设置在所述第二凹槽内。
在一种可选择的实现方式中，第一密封胶条还包括壳体密封部，所述壳体密封部与所述第一凹槽的结构相匹配，设置在所述第一凹槽内。
在一种可选择的实现方式中，护盖边框包括面向所述第二腔室边框的第二边框顶面，所述第二边框顶面包括第三凹槽，所述第三凹槽与所述第二凹槽对应设置。
在一种可选择的实现方式中，第二密封胶条包括用于与所述第一线缆密封部对接的第二线缆密封部，所述第二线缆密封部与所述第二凹槽的结构相匹配，设置于所述第三凹槽内。
这样，由于第二凹槽与第三凹槽相对应设置，因此在护盖扣合之后，第一线缆密封部和第二线缆密封部可以相互对接，以利于壳体边框与护盖之间的密封并且对外部线缆形成夹持。
在一种可选择的实现方式中，线缆通道包括上下对接设置的下部线缆通道和上部线缆通道；所述下部线缆通道设置于所述第一边框顶面和所述第一线缆密封部的面向所述护盖的表面；所述上部线缆通道设置于所述第二边框顶面和所述第二线缆密封部的面向所述第二腔室边框的表面。由此，在第一线缆密封部和第二线缆密封部相互对接之后，下部线缆通道和上部线缆通道能够形成完整的线缆通道，以压紧线缆，在线缆与壳体和护盖之间形成密封。
在一种可选择的实现方式中，下部线缆通道沿外部线缆的引出方向依次包括第一内部出线口、第一线槽和第一外部出线口；所述第一内部出线口和所述第一外部出线口设置于第一边框顶面，所述第一内部出线口从所述第二腔室边框的内壁延伸到所述第二凹槽，所述第一外部出线口从所述第一凹槽延伸到所述第二腔室边框的外壁；所述第一线槽设置于所述第一线缆密封部的面向所述护盖的表面，从所述第一内部出线口延伸至所述第一外部出线口。
在一种可选择的实现方式中，上部线缆通道沿外部线缆的引出方向依次包括第二内部出线口、第二线槽和第二外部出线口；所述第二内部出线口和所述第二外部出线口设置于第二边框顶面，所述第二内部出线口从所述护盖边框的内壁延伸到所述第三凹槽，所述第二外部出线口从所述护盖边框的外壁延伸到所述第三凹槽；所述第二线槽设置于 所述第二线缆密封部的面向所述第二腔室边框的表面，从所述第二内部出线口延伸至所述第二外部出线口。
在一种可选择的实现方式中，第一线槽的槽面和所述第二线槽的槽面均为半圆柱面。这样，第一线槽和第二线槽对接之后，能够形成完成的圆柱形槽面，该圆柱形槽面可以与外部线缆的形状相匹配，使其与外部线缆紧密贴合，不留缝隙，提高密封效果。
在一种可选择的实现方式中，第一线槽的槽面设置有至少一个第一槽筋，所述第二线槽的槽面设置有至少一个第二槽筋，所述第一线槽和所述第二槽筋与外部线缆的引出方向垂直；所述第一槽筋与所述第二槽筋的数量相同并且一一对应设置，具有对应关系的所述第一槽筋与所述第二槽筋位于同一平面内，用于从上下两个方向压紧外部线缆。这样，每一组具有对应关系的第一槽筋和第二槽筋都能够从两个方向压紧外部线缆而形成一道密封，由此形成多道密封，增强阻止液体从外部线缆和第一线槽、第二线槽之间进入到壳体内部的能力。
在一种可选择的实现方式中，第一线槽在靠近所述第一内部出线口的一端设置有用于外部线缆穿过的密封环；所述第二线槽在靠近所述第二内部出线口的一端设置有用于所述密封环嵌入的环形槽，所述环形槽的半径小于或者等于所述密封环的外圆半径。这样，密封环能够在第一线缆密封部和第二线缆密封部之间的压力作用下与环形槽紧紧贴合，形成密封，阻止液体从第一线缆密封部和第二线缆密封部之间进入到壳体内部。
在一种可选择的实现方式中，第一线缆密封部还包括第一凸出部，所述第一凸出部位于所述第一线缆密封部的面向所述护盖的表面，分布在所述第一线槽的两侧；所述第一凸出部沿着外部线缆的引出方向从所述第一线缆密封部的一端延伸到所述第一线缆密封部的另一端。
在一种可选择的实现方式中，第二线缆密封部还包括第二凸出部，所述第二凸出部位于所述第二线缆密封部的面向所述第二腔室边框的表面，分布在所述第二线槽的两侧，并且与所述第二凸出部对应设置；所述第二凸出部沿着外部线缆的引出方向从所述第二线缆密封部的一端延伸到所述第二线缆密封部的另一端。
这样，在护盖扣合状态下，每一组具有对应关系的第一凸出部176和第二凸出部可以相互接触并挤压，从而产生形变，第一凸出部和第二凸出部之间挤压产生的压力使得第一凸出部和第二凸出部紧密贴合，提高第一线槽、第二线槽交界处的密封效果。
在一种可选择的实现方式中，第一密封胶条还包括线缆通道密封部；所述线缆通道密封部包括延长胶条和密封胶塞；所述延长胶条一端设置在所述第一线缆密封部的面向所述第一外部出线口的一侧，另一端穿过所述第一外部出线口延伸到所述壳体外部；所述密封胶塞为圆柱形结构，所述密封胶塞的一个圆形底面与所述延长胶条的位于所述壳体外部的一端连接。这样，当线缆通道没有外部线缆引出时，可以将密封胶塞嵌入到线缆通道内以封堵线缆通道，形成密封，阻止液体从线缆通道进入到壳体内部。
第二方面，本申请实施例提供了一种车辆，包括上述第一方面及其各个实现方式中的电子设备。

具体实施方式
自动驾驶汽车(autonomous vehicles；self-piloting automobile)，又称无人驾驶汽车、电脑驾驶汽车或轮式移动机器人，为一种运输动力的无人地面载具。作为自动化载具， 自动驾驶汽车不需要人类操作即能感测其环境及导航。自动驾驶汽车能以雷达、光学雷达、卫星导航系统(global navigation satellite system，GNSS)及电脑视觉等技术感测其环境。自动驾驶汽车配备的控制系统能将感测资料转换成适当的导航道路，以及障碍与相关标志，以更新地图资讯，实时追踪自身的位置，并且实时控制或者辅助驾驶员控制车辆的驾驶行为。
自动驾驶车辆的控制系统，尤其是高等级的自动驾驶车辆的控制系统一般包括车载计算模块(或自动驾驶计算平台)，例如移动数据中心(mobile data center，MDC)。车载计算模块能够通过摄像机、激光雷达、毫米波雷达、超声波等车载传感器来感知周围的环境，依据所获取的信息进行决策判断，由适当的工作模型来制定相应的策略，如预测本车与其他车辆、行人等在未来一段时间内的运动状态，并进行避免碰撞路径规划。
由于车辆在日常行驶过程中会面对自然环境中的粉尘、雨水和外物侵入，还会存在行进涉水路面等场景，因此车辆中的车载计算模块，以及车辆的其他用于进行车辆控制或数据计算的电气设备或者单元(例如电子控制单元(electronic control unit，ECU)或者整车控制器(vehicle control unit，VCU)等)通常会被要求具备一定的防水防尘性能。
防水防尘性能通常以国际防护等级(international protection marking，IEC 60529)来表示，国际防护等级也称异物防护等级(ingress protection rating)或IP代码(IP Code)。有时候也被叫做“防水等级”“防尘等级”等。国际防护等级是由国际电工委员会(international electrotechnical commission，IEC)起草的一个防护等级标准，定义了机械和电子设备能提供针对固态异物侵入(包括身体部位如手指，灰尘，砂砾等)、液态渗入、意外接触有何等程度的防护能力。
国际防护等级具体通过IP代码来表示，IP代码包括IP和两个数字组成，例如IP54、IP68等。第1个数字表示设备的固态微粒防护等级(即防尘等级)，第2个数字表示设备的液体渗透防护(即防水等级)，数字越大表示其防护等级越高。这两个数字的取值范围一般为1～9之间的整数，一些情况下还可以为字母X，表示有意不给出相应的异物入侵或灰尘方面的防护信息，例如：IPX7表示设备在浸入不超过1m深的水下时，能给予内部零件不低于30分钟的防护时间，但是未提供防尘方面的防护信息。另外，IP代码还可以在两个数字后面增加额外的英文表示其他防护能力，例如IPX9K中的9K表示设备对高温高压水柱的防护能力，具体表示设备可在制造商指定的条件下承受近距离的高温高压水柱冲击不低于2分钟。
车辆中的车载计算模块、ECU、VCU等设备的IP防护等级的要求一般可以根据其安装位来确定。例如，当设备安装在驾驶舱内等环境较好的位置时，IP防护等级要求较低，例如防水等级至少为IPX2，当设备装在车底、驾驶舱等环境相对恶劣的位置时，IP防护等级要求较高，例如防水等级至少为IPX7、IPX9K。
在车载计算模块等设备中，车载连接器用于将设备与外部线缆连接，实现设备与线缆另一端的其他设备之间的通信。根据车载连接器的支持的通信速率的高低不同，车辆连接器分为低速连接器和高速连接器。
传统的非自动驾驶车辆一般只包含低算力的车载计算模块或者ECU等设备，这些设备由于算力低，结构也相对简单，尺寸很小，可以安装在车辆的中控台内，因此设备的防水等级要求较低，通常只需要满足IPX2级别即可。一般来说，车载计算模块、ECU等设备的防水主要包括设备壳体的防水、设备壳体与车载连接器之间的防水和车载连接 器与线缆之间的防水。
在传统的非自动驾驶车辆中，车载计算模块或者ECU等设备通常配备的是低速连接器。图1示出的是配备低速连接器的ECU的结构分解示意图。如图1所示，ECU包括上壳体11、下壳体12、印刷电路板(printed circuit board，PCB)13和低速连接器14；上壳体11和下壳体12在扣合状态下能够形成用于容纳低速连接器14的开口15；低速连接器14设置于壳体的开口15处，一端与壳体内的PCB 13连接，另一端位于壳体外，用于与线缆连接。其中，低速连接器14设置有与开口形状匹配的底座16，在ECU壳体扣合状态下，上壳体11与下壳体12之间可以通过点胶17密封，壳体与低速连接器14之间可以通过在开口15与底座16连接面上点胶17密封，以满足整机防水要求，技术方案比较成熟。
然而，随着自动驾驶技术的进步，车辆的自动驾驶等级不断提高，车载计算模块需要实现的功能越来越多，所需的算力也越来越大，结构越来越复杂，尺寸也越来越大。由于车辆中控台空间有限，大尺寸的计算模块只能安装在乘客舱的作为下方或者发动机的前舱内，工作环境相对恶劣，因此要求车载计算模块的整机防水等级要达到IPX7以上。
另外，在高等级的自动驾驶车辆中，各传感器与车载计算模块之间的通信速率和带宽需求越来越高，低速连接器已经无法满足传感器与车载计算模块之间的通信需求，因此高等级自动驾驶车辆的车载计算模块需要配备高速连接器。对于高速连接器与车载计算模块壳体之间、以及高速连接器公头端子和母头端子之间的满足IPX7等级的防水设计，目前尚无成熟的实现方案。
图2是目前配备有高速连接器的车载计算模块的防水方案示意图。如图2所示，多个高速连接器18可以通过定制设计的方式被共同设置在一个底座19之上，车载计算模块的上壳体11和下壳体12在扣合状态下可以形成与底座19尺寸和形状相匹配的开口20，从而可以将底座19设置于开口20之内。其中，上壳体11与下壳体12的连接处、底座19与上壳体11的连接处、底座19与下壳体12的连接处均可以通过点胶密封，以具备防水能力。
然而，图2示出的这种定制高速连接器结合防水密封胶的防水方案在实际应用中至少存在以下技术问题：1、车载计算模块需要使用定制的高速连接器，无法使用符合行业标准结构的连接器，通用性差；2、用于采用了防水密封胶进行壳体之间的连接，导致壳体难以难度大，在拆卸过程中容易损伤设备主板200，并且一旦拆卸，防水结构就会被破坏，难以复原；3、定制的高速连接器占用的空间更大，会增大车载计算模块的尺寸，不利于在车辆上安装。
为了解决上述问题，本申请实施例提供了一种电子设备，该电子设备例如可以是车载计算模块、ECU、VCU，或者其他设备，该电子设备允许在使用标准结构的高速连接器的前提下具备IPX7等级的防水能力。
为便于本领域技术人员深刻理解本申请的技术方案，图3示出了车载计算模块的在车辆中的安装场景。如图3所示，车载计算模块21一般安装在车身内，例如中控台内、座椅下或者发送机舱等位置。与车载计算模块21协同地，车辆还安装有各类型的传感器，例如激光雷达22、摄像头23、毫米波雷达24等，以探测车辆所处的环境、车辆自身状态等、并将探测到的数据反馈给车载计算模块21。车载计算模块21利用其内置的人工智能(artificial intelligence，AI)芯片，例如神经网络处理器(neural-network processing unit， NPU)对接收到的数据进行实时推理运算，并且根据运算结果生成操作指令下发给整车控制器(vehicle control unit，VCU)25。VCU根据操作指令控制车辆制动，例如刹车、减速等，实现各种级别的自动驾驶功能。计算模块还可以通过车载通信终端(telematics box，T-BOX)26将数据上传到网络后端的云数据中心。一般来说，车载计算模块21与摄像头23之间可以通过吉比特多媒体串行链路(gigabit multimedia serial link，GMSL)进行信息传输；车载计算模块21与激光雷达22之间可以通过车载以太链路进行信息传输；车载计算模块21与VCU25或者电机控制器(motor control unit，MCU)和电池管理系统(battery management system，BMS)之间可以通过控制器局域网(controller area network，CAN)总线进行信息传输；车载计算模块21与毫米波雷达24之间可以通过CAN总线进行信息传输；车载计算模块21与超声波雷达(图2中未示出)之间可以通过本地互联网络(local interconnect network，LIN)总线进行信息传输；车载计算模块21与T-BOX26之间可以通过以太链路进行信息传输。
下面以车载计算模块为例，对本申请实施例提供的电子设备的具体结构进行阐述说明。
图4是本申请实施例提供的电子设备的示意图。如图4所示，该电子设备包括壳体100和设备主板200，为便于描述电子设备的内部结构，图4中对壳体100进行了剖切。其中，壳体100内部包括用于容纳电子设备内部器件的第一腔室110和第二腔室120。第二腔室120位于第一腔室110的一侧，与第一腔室110相邻设置。第一腔室110与第二腔室120相互连通。
设备主板200设置于第一腔室110内。设备主板200上设置有至少一个连接器130，其中，上述至少一个连接器130可以并列设置在设备主板200的靠近第二腔室120的位置。并且上述至少一个连接器130的用于与外部线缆连接的一端从第一腔室110延伸到第二腔室120内。
本申请实施例中的连接器130可以是高速连接器，也可以使低速连接器，优选为高速连接器。一般来说，低速连接器由于技术出现时间早、发展时间长，通常已经具备了防水性能，而高速连接器由于技术出现时间晚、发展时间短，目前多数还不具备防水能力。换一种描述方式来说，本申请实施例中的连接器130可以是具备防水性能的连接器和不具备防水性能的连接器。
进一步如图4所示，壳体100在第二腔室120的区域包括第二腔室底面140、第二腔室边框150和护盖160。其中，第二腔室边框150围绕第二腔室底面140设置，第二腔室边框150在垂直于第二腔室底面140的方向上具有一定的高度，以形成第二腔室120的一部分深度；护盖160用于扣合在第二腔室边框150之上，以将第二腔室120封闭。第二腔室边框150在平行于第二腔室底面140的方向具有一定的宽度，由此，第二腔室边框150能够在面向护盖160的一端形成具有一定宽度的第一边框顶面151。
第一边框顶面151为环形顶面，根据第二腔室120形状的不同，第一边框顶面151可以具有不同的形状，例如：当第二腔室120是一个矩形腔室时，第一边框顶面151是一个矩形环顶面，当第二腔室120是一个圆形腔室时，第一边框顶面151可以是一个圆环顶面。因此，本申请实施例对第一边框顶面151的形状不做具体限定。
图5是本申请实施例提供的第二腔室边框的结构局部示意图。如图5所示，第一边框顶面151设置有第一凹槽152，第一凹槽152在第一边框顶面151上围绕着第二腔室 120呈环形设置。第一凹槽152距离第二腔室边框150的内壁的距离小于第一凹槽152距离L1第二腔室边框150的外壁的距离L2，其中，第二腔室边框150的内壁是指第二腔室边框150的面向第二腔室120的壁面，第二腔室边框150的外壁是指第二腔室边框150的面向壳体外部的壁面。

本申请实施例提供的电子设备还包括第一密封胶条170。第一密封胶条170用于嵌入安装到第一凹槽152、第二凹槽153内。图6是本申请实施例提供的第一密封胶条170的结构示意图。结合图5和图6所示，第一密封胶条170具有与第一凹槽152、第二凹槽153的形状和尺寸相匹配的环形结构。具体来说，第一密封胶条170可以包括壳体密封部171和第一线缆密封部172。其中，壳体密封部171具有与第一凹槽152的形状和尺寸相配的结构，可以嵌入到第一凹槽152内；第一线缆密封部172具有与第二凹槽153的形状和尺寸相配的结构，可以嵌入到第二凹槽153内。
本申请实施例中，当第一边框顶面151设置有多个第二凹槽153时，第一密封胶条170可以包括与第二凹槽153数量相等的多个第一线缆密封部172，相邻两个第一线缆密封部172通过第一连接部177连接，这样，多个第一线缆密封部172可以分别嵌入到各个第二凹槽153中，第一连接部177可以嵌入到第一连接槽156中(见图5)，例如图6示出的第一边框顶面151包括两个第二凹槽153，相应地，第一密封胶条170包括两个第一线缆密封部172。
图7是本申请实施例示出的第一凹槽152与第一密封胶条170的安装示意图。结合图5和图7所示，在第一密封胶条170嵌入第一凹槽152之后，第一边框顶面151和第一线缆密封部172的面向护盖160的表面形成至少一个用于外部线缆引出的下部线缆通道180，下部线缆通道180从第二腔室120贯通至壳体外部。其中，每一个下部线缆通道180沿外部线缆的引出方向D1依次包括一个设置在第一边框顶面151上的第一内部出线口154、一个设置在第一线缆密封部172上的第一线槽173、以及一个设置在第一边框顶面151上的第一外部出线口155，并且第一内部出线口154、第一线槽173和第一外部出线口155位于同一轴线上。第一内部出线口154从第二腔室边框150的内壁延伸到第二凹槽153，将第二腔室120与第二凹槽153连通，第一内部出线口154在垂直于第一边框顶面151方向上的深度小于第二凹槽153在垂直于第一边框顶面151方向上的深度。第一外部出线口155从第一凹槽152延伸到第二腔室边框150的外壁，将第一凹槽152与壳体外部连通，第一外部出线口155在垂直于第一边框顶面151方向上的深度小于第二凹槽153在垂直于第一边框顶面151方向上的深度。第一线槽173设置在第一线缆密封部172的面向护盖160的表面，从第一内部出线口154延伸至第一外部出线口155。
当电子设备包括多个下部线缆通道180时，多个下部线缆通道180沿着第一密封胶条170的长度方向在第二腔室边框150和第一线缆密封部172上间隔并列设置。可以理解的是，当电子设备包括多个下部线缆通道180，并且第一密封胶条170包括多个第一线缆密封部172时，每一个第一线缆密封部172上可能并列设置有至少一个第一线槽173。例如在图7示出的结构中，电子设备包括6个下部线缆通道180、第一密封胶条170包括2个第一线缆密封部172，那么每一个第一线缆密封部172上可以设置有3个第一线槽173。
图8是本申请实施例提供的下部线缆通道的局部放大示意图。如图8所示，在一种可选择的实现方式中，第一线槽173的槽面为半圆柱面。第一线槽173的槽面上还可以设置有至少一个第一槽筋174，第一槽筋174与外部线缆的引出方向D1垂直。当第一槽筋174数量为多个时，多个第一槽筋174沿着外部线缆的引出方向D1间隔并列设置。
在一种可选择的实现方式中，每个第一线槽173在靠近第一内部出线口154的一端还设置有一个密封环175，密封环175的中心轴与外部线缆的引出方向D1垂直，密封环175的内圆半径优选大于第一线槽173的半圆柱面的半径。
在一种可选择的实现方式中，第一线缆密封部172还包括第一凸出部176，第一凸出部176设置在第一线缆密封部172的面向护盖160的表面，第一凸出部176以第一线槽173的轴线C1为对称轴，对称地分布在第一线槽173的两侧，因此每个第一线槽173对应两个第一凸出部176。第一凸出部176沿着外部线缆的引出方向D1从第一线缆密封部172的一端延伸到第一线缆密封部的另一端。第一凸出部176在垂直于第一边框顶面151的方向具有一定的高度，并且该高度在远离第一线槽173的轴线C1的方向上逐渐减小，形成一个坡型结构。
图9是本申请实施例提供的第一凹槽与第一密封胶条的安装后的A向剖视图。如图9所示，作为一种优选的实现方式，第一凹槽152可以是矩形槽；壳体密封部171的宽度小于或者等于第一凹槽152的宽度，与第一凹槽152形成间隙配合；壳体密封部171的高度大于第一凹槽152的高度，这样，壳体密封部171可以有一部分嵌入到第一凹槽152内，而另一部分高出第一边框顶面151，位于第一凹槽152之外。为了与第一凹槽152结构匹配，壳体密封部171的位于第一凹槽152内的部分的截面形状也可以为矩形。壳体密封部171的位于第一凹槽152外的部分可以包括两条朝着护盖160方向(见图7)凸出的弧形结构182，两条弧形结构182沿着壳体密封部171的宽度方向并列设置。
图10是本申请实施例提供的护盖160的结构示意图。如图10所示，护盖160包括护盖顶面161和护盖边框162。其中，护盖顶面161的形状和尺寸与第二腔室底面140(见图4)的形状和尺寸相匹配，护盖边框162围绕护盖顶面161设置，并且护盖边框162在垂直于护盖顶面161的方向上具有一定的高度，以形成第二腔室120的另一部分深度。护盖边框162在平行于护盖顶面161的方向具有一定的宽度，该宽度优选与第二腔室边框150的宽度相等，由此，护盖边框162能够在面向第一边框顶面151的方向形成与第一边框顶面151的形状和尺寸相匹配的第二边框顶面163。
本申请实施例中，护盖160与壳体100可以通过孔轴、铰链等方式连接，使得护盖160可以沿着某一旋转轴相对于壳体100翻转，实现护盖160与壳体100之间的扣合和开启。当护盖160与壳体100之间是扣合状态时，第一边框顶面151与第二边框顶面163相互对接贴合。
进一步如图10所示，第二边框顶面163还设置有至少一个第三凹槽164，第三凹槽164与第二凹槽153的数量相同，并且第三凹槽164与第二凹槽153的位置一一对应，第三凹槽164的形状和尺寸与第二凹槽153的形状和尺寸相匹配。当第二边框顶面163包括多个第三凹槽164时，相邻两个第三凹槽164通过第二连接槽165连通。
本申请实施例提供的电子设备还包括第二密封胶条190。第二密封胶条190用于嵌入到第三凹槽164中。图11是本申请实施例提供的第二密封胶条190的结构示意图。如图11所示，第二密封胶条190包括至少一个与第三凹槽164的形状相匹配的第二线缆密封部191。第二线缆密封部191与第三凹槽164的数量相同，并且位置一一对应，这样，每一个第二线缆密封部191都可以嵌入到一个第三凹槽164内。另外，当第二密封胶条190包括多个第二线缆密封部191时，相邻两个第二线缆密封部191之间还可以包括第二连接部192，第二连接部192用于将多个第二线缆密封部191连接成一体结构，第二连接部192与第二连接槽165的位置和尺寸相匹配，能够嵌入到第二连接槽165中。
图12是本申请实施例示出的第三凹槽164与第二密封胶条190的安装示意图。如图12所示，在第二密封胶条190嵌入到第三凹槽164之后，第二边框顶面163和第二线缆密封部191的面向第一边框顶面151的表面形成至少一个用于外部线缆引出的上部线缆通道210，上部线缆通道210从第二腔室120贯通至壳体外部，上部线缆通道210的数量与下部线缆通道180(见图7)的数量相同，并且位置一一对应。其中，每一个上部线缆通道210沿外部线缆的引出方向D1依次包括一个设置在第二边框顶面163上的第二内部出线口166、一个设置在第二线缆密封部191上的第二线槽193、以及一个设置在第二边框顶面163上的第二外部出线口167，并且第二内部出线口166、第二线槽193和第二外部出线口167位于同一轴线上。第二内部出线口166从护盖边框162的内壁延伸到第三凹槽164，将第二腔室120与第三凹槽164连通，第二内部出线口166在垂直于第二边框顶面163方向上的深度小于第三凹槽164在垂直于第二边框顶面163方向上的宽度。第二外部出线口167从护盖边框162的外壁延伸到第三凹槽164，将第三凹槽164与壳体外部连通，第二外部出线口167在垂直于护盖边框162顶面方向上的深度小于第三凹槽164在垂直于第二边框顶面163方向上的深度。第二线槽193设置在第二线缆密封部191的面向第二腔室边框150的表面，从靠近第二内部出线口166的一侧延伸至靠近第二外部出线口167的一侧。
进一步如图12所示，当电子设备包括多个上部线缆通道210时，多个上部线缆通道210在护盖边框162和第二线缆密封部191上间隔并列设置。可以理解的是，当电子设备包括多个上部线缆通道210，并且每一个第二密封胶条190包括多个第二线缆密封部191时，每一个第二线缆密封部191上可能并列设置有至少一个第二线槽193。例如在图12示出的结构中，电子设备包括6个上部线缆通道210、第二密封胶条190包括2个第二线缆密封部191，那么每一个第二线缆密封部191上可以设置有3个第二线槽193。
图13是本申请实施例提供的上部线缆通道的局部放大示意图。如图13所示，在一种可选择的实现方式中，第二线槽193的槽面为半圆柱面。第二线槽193的槽面上还可以设置有至少一个第二槽筋194，第二槽筋194与外部线缆的引出方向D1垂直。当第二槽筋194数量为多个时，多个第二槽筋194沿着外部线缆的引出方向D1间隔并列设置。
在一种可选的方式中，每个第二线槽193在靠近第二内部出线口166的一端还设置有一个与第一线槽173的密封环175相对应的环形槽195，环形槽195的半径优选大于 第二线槽193的半圆柱面的槽面的半径，并且优选小于或者等于第一线槽173的密封环175(见图8)的外圆半径。
在一种可选择的实现方式中，第二密封胶条190在垂直于第二边框顶面163方向上的厚度大于第三凹槽164在垂直于第二边框顶面163方向上的深度，从而使得第二密封胶条190凸出于第二边框顶面163。
在一种可选择的实现方式中，第二线缆密封部191还包括第二凸出部196，第二凸出部196设置在第二线缆密封部191的面向第一边框顶面151(见图12)的一侧，第二凸出部196以第二线槽193的轴线C2为对称轴，对称地分布在第二线槽193的两侧，因此每个第二线槽193对应两个第二凸出部196，并且第二凸出部196与设置在第一线缆密封部172的第一凸出部176具有一一对应的关系。第二凸出部196沿着外部线缆的引出方向D1从最靠近第二内部出线口166的第二槽筋194处延伸到最靠近第二外部出线口167的第二槽筋194处。第二凸出部196在垂直于第二边框顶面163的方向具有一定的高度，并且该高度在远离第二线槽193的轴线C2的方向上逐渐减小，形成一个坡型结构。
图14是本申请实施例提供的电子设备与外部线缆连接的示意图。如图14所示，外部线缆的包括线体310以及设置于线体310一端的接线端子320。其中，接线端子320设置于第二腔室120内，与连接器130插接。线体310从第二腔室120内部依次穿过第一内部出线口154、密封环175、第一线槽173和第二外部出线口167，从而延伸到电子设备外部。
进一步如图14所示，第二腔室边框150上包括多个第一定位孔157。多个第一定位孔157间隔设置在第一边框顶面151上，并且向第二腔室边框150内部内形成一定的深度。第一定位孔157优选为盲孔。作为一种优选的实现方式，第一定位孔157设置在第一密封胶条170与第二腔室边框150的外壁之间，护盖边框162上还包括多个第二定位孔168，上述多个第二定位孔168间隔设置在第二边框顶面163上，第二定位孔168为通孔。当护盖160为扣合状态时，上述多个第二定位孔168与多个第一定位孔157一一对应同轴分布。这样，如图14所示，在护盖160扣合后，可以使用螺钉旋入第二定位孔168和第一定位孔157中，将护盖160与壳体通过螺纹连接实现固定和锁紧。
图15是护盖160扣合时的壳体100、护盖160和第一密封胶条170的配合关系示意图。如图15所示，在护盖160扣合状态下，第一边框顶面151与第二边框顶面163能够紧密贴合。位于第一边框顶面151的至少一个下部线缆通道180与位于第二边框顶面163的至少一个上部线缆通道210一一对应上下对接，形成至少一个完整的线缆通道。
图16是第一密封胶条的壳体密封部171与第一边框顶面151和第二边框顶面163的配合关系图。如图16所示，在护盖扣合状态下，由于壳体密封部171高出第一边框顶面151，壳体密封部171会受到第二边框顶面163的挤压而产生形变。形变后的壳体密封部171会对与其接触的第一凹槽152的内壁和第二边框顶面163产生一定的压力，使得壳体密封部171与第一凹槽152的内壁和第二边框顶面163紧密贴合，形成密封，阻止液体和灰尘从壳体外部进入到壳体内部。进一步地，由于壳体密封部171包括两个朝着护盖160方向凸出的弧形结构，因此，在护盖160扣合状态下，这两个弧形结构可以分别与第二边框顶面163紧密接触，从而使得壳体密封部171与护盖160之间形成两道密封，提高防水防尘效果。
图17是护盖160扣合状态下的线缆与第一线缆密封部172和第二线缆密封部191的 配合关系图。如图17所示，在护盖160扣合状态下，第一边框顶面151与第二边框顶面163紧密贴合。这时，第一线缆密封部172与第二线缆密封部191会相互挤压而产生形变，形变产生的压力会使得第一线缆密封部172和第二线缆密封部191紧密贴合，形成密封，阻止液体和灰尘从第一线缆密封部172和第二线缆密封部191的交界处进入到壳体内部。
进一步结合图17所示，在护盖160扣合状态下，第一线缆密封部172的第一线槽173和第二线缆密封部191的第二线槽193相互对接，其半圆柱型的槽面在对接后能够形成用于容纳线缆的完整的圆柱形槽面。在此基础上，设置于第一线槽173上的至少一个第一槽筋174与设置在第二线槽193上的至少一个第二槽筋194数量相同，并且一一对应。每一组具有对应关系的第一槽筋174和第二槽筋194优选位于同一个平面内，从上下两个方向压紧线体310，形成一道密封，阻止液体和灰尘从线体310和第一线槽173、第二线槽193之间进入到壳体内部。
可以理解的是，当一一对应的第一槽筋174和第二槽筋194的数量为多个时，每一组具有对应关系的第一槽筋174和第二槽筋194都会形成一道密封，因此可以在线缆和第一线槽173、第二线槽193之间形成多道密封，增强阻止液体和灰尘从线缆和第一线槽173、第二线槽193之间进入到壳体内部的能力。
进一步如图17所示，在护盖160扣合状态下，第一线缆密封部172的密封环175能够嵌入到第二线缆密封部191的环形槽195内，并且密封环175能够在第一线缆密封部172和第二线缆密封部191之间的压力作用下与环形槽195紧紧贴合，形成密封，阻止液体和灰尘从第一线缆密封部172和第二线缆密封部191之间进入到壳体内部。
另外，可以理解的是，在第一线缆密封部172和第二线缆密封部191的压力作用下，形变后的第一线缆密封部172会对第二凹槽153的底面和侧面产生一定的压力，使得第一线缆密封部172与第二凹槽153的底面和侧面紧密接触，形成密封，阻止液体和灰尘从第一线缆密封部172和护盖160之间进入到壳体内部。同样地，形变后的第二线缆密封部191会对第三凹槽164的底面和侧面产生一定的压力，使得第二线缆密封部191与第三凹槽164的底面和侧面紧密接触，形成密封，阻止液体和灰尘从第二线缆密封部191和壳体100之间进入到壳体内部。
图18是第一凸出部176和第二凸出部196的配合示意图。如图18所示，在护盖160扣合状态下，每一组具有对应关系的第一线槽173和第二线槽193两侧的第一凸出部176和第二凸出部196相互接触并挤压，从而产生形变。这样，第一凸出部176和第二凸出部196之间会产生较大的压力，使得第一凸出部176和第二凸出部196紧密贴合，提高第一线槽173、第二线槽193交界处的密封效果。
由以上技术方案可知，本申请实施例提供的电子设备，壳体上设置有可开启和扣合的护盖，该电子设备将不具备防水性能的连接器设置于壳体内部，外部线缆在壳体内部与连接器连接，然后从壳体内引入到壳体外。为便于线缆引出，壳体与护盖的扣合面具有至少一个线缆通道，并且出线口周围还设置了第一密封胶条和第二密封胶条等壳体密封部件。当护盖扣合时，壳体和护盖能够压紧第一密封胶条，在壳体和护盖之间形成密封，同时，第一密封胶条和第二密封胶条能够压紧线缆，在线缆与壳体和护盖之间形成密封，这样壳体外部的液体和灰尘等不会进入到壳体内部，使得电子设备在使用不具备防水性能的连接器时也能具备防水防尘能力。
图19是本申请实施例提供的另一种第一密封胶条的结构示意图。如图19所示，第一密封胶条170还包括至少一个线缆通道密封部178，线缆通道密封部178的数量与第一密封胶条170上设置的第一线槽173的数量有关，一般小于或者等于第一线槽173的储量。当线缆通道密封部178的数量与第一线槽173的数量相同时，意味着每一个第一线槽173都对应设置有一个线缆通道密封部178；当线缆通道密封部178的数量少于第一线槽173的数量时，只有一部分第一线槽173对应设置有线缆通道密封部178。线缆通道密封部178包括延长胶条179和密封胶塞181，其中延长胶条179一端设置在第一线缆密封部172的面向第一外部出线口155的一侧，另一端穿过第一外部出线口155延伸到壳体外部，密封胶塞181为圆柱形结构，其一个圆形底面与延长胶条179的位于壳体外部的一端连接。
图20是本申请实施例提供的线缆通道密封部178的使用方式示意图。如图20所示，当从壳体内引出的线缆的数量小于线缆通道的数量时，可以使用线缆通道密封部178将未有线缆引出的线缆通道封堵，以保持电子设备的防水防尘能力。具体实现中，在扣合护盖160之前，可以将延长胶条179向壳体方向弯折，以将密封胶塞181放置于第一线槽173内，然后再扣合护盖160。这样，第一线槽173的第一槽筋174和第二线槽193的第二槽筋194可以从上下两个相对的方向压紧密封胶塞181，形成密封，阻止液体和灰尘从线缆通道进入到壳体内部，此时，密封胶塞181的角色相当于线缆。
下面结合更多附图对本申请实施例的壳体结构进行进一步的描述。
图21是本申请实施例提供的壳体结构的分解示意图。如图21所示，壳体100可以包括上壳体410、下壳体420，上壳体410和下壳体420上下扣合，形成第一腔室110和第二腔室120。其中，下壳体420包括下壳体底面421，以及围绕在下壳体底面421边缘设置的下壳体边框422，下壳体边框422在垂直于下壳体底面421的方向上具有一定的高度，以垂直于下壳体底面421的方向上形成上述第一腔室110的下半部分和第二腔室120的下半部分。下壳体底面421可以包括用于构成第一腔室110的底面区域以及用于构成第二腔室120的底面区域。本申请实施例中，第一腔室110和第二腔室120可以根据需求被设计成任意形状，因此本申请实施例对下壳体底面421的形状和尺寸不做限定。
进一步如图21所示，下壳体边框422在平行于下壳体底面421的方向具有一定的宽度，由此在面向上壳体410一侧形成第四边框顶面423。第四边框顶面423设置有连续的第四凹槽424。进一步地，下壳体边框422还包括多个第一螺孔支座425，多个第一螺孔支座425间隔分布地设置在下壳体边框422的内侧，第一螺孔支座425的宽度大于下壳体边框422的宽度。
在一种可选择的实现方式中，第一螺孔支座425可以是从下壳体边框422凸出的圆弧形结构。第四凹槽424在途径第一螺孔支座425时，可以适应第一螺孔支座425的轮廓向下壳体边框422的内侧偏移，这样，第一螺孔支座425在第四凹槽424与下壳体边框422外侧之间形成面积较大的平整区域。进一步地，下壳体边框422还设置有多个第三定位孔426，多个第三定位孔426间隔分布在各个第一螺孔支座425上，优选设置在第四凹槽424与下壳体边框422外侧之间的平整区域，第三定位孔426为通孔，沿着垂直下壳体底面421的方向贯穿下壳体边框422。
进一步如图21所示，本申请实施例提供的电子设备还包括第三密封胶条427，第三密封胶条427具有与第四凹槽424的形状和尺寸相配合的环形结构，能够嵌入到第四凹 槽424内。第三密封胶条427在垂直于第四边框顶面423方向上的厚度大于第四凹槽424的深度，这样在第三密封胶条427嵌入之后，第三密封胶条427可以高出第四边框顶面423。进一步地，第一密封胶条170的壳体密封部171的面向上壳体410的方向可以包括两条朝着护盖160方向凸出的弧形结构，两条弧形结构沿着第三密封胶条427的宽度方向并列设置。
图22是本申请实施例示出的上壳体410的结构示意图。如图22所示，上壳体410包括上壳体顶面411、上壳体边框412和护盖160。其中，上壳体边框412的一部分与上壳体顶面411共同围成第一腔室110的上半部分；上壳体边框412的另一部分与护盖160共同围成第二腔室120的上半部分。上壳体边框412的用于围成第二腔室120的部分即对应本申请实施例之前描述的第二腔室边框150。
进一步如图22所示，上壳体410在位于第一腔室110和第二腔室120的相邻处设置有至少一个定位槽413，定位槽413从第一腔室110一侧延伸至第二腔室120一侧，当有多个定位槽413时，多个定位槽413间隔并列设置。本申请实施例中，从设备主板200上引出的连接器130(见图21)设置于定位槽413内，因此定位槽413起到限位连接器130和隔离多个连接器130的作用。本申请实施例优选每个定位槽413内设置一个连接器130，因此定位槽413的数量大于或者等于需要防水的连接器130的数量。
进一步如图22所示，上壳体边框412用于围成第一腔室110的部分在平行于上壳体顶面411的方向具有一定的宽度，由此在面向下壳体420(见图21)一侧形成用于与第四边框顶面423(见图21)相互对接的第五边框顶面414。第五边框顶面414的宽度优选与第四边框顶面423的宽度相同。进一步地，上壳体边框412还包括多个与第一螺孔支座425(见图21)一一对应的多个第二螺孔支座415，多个第二螺孔支座415间隔分布地设置在上壳体边框412的内侧，第一螺孔支座425的宽度大于上壳体边框412的宽度。
在一种可选择的实现方式中，第二螺孔支座415可以是从上壳体边框412凸出的圆弧形结构，其尺寸和形状与第一螺孔支座425的尺寸和形状相同。进一步地，上壳体边框412还设置有多个第四定位孔416，多个第四定位孔416间隔分布在各个第二螺孔支座415上，与多个第三定位孔426一一对应同轴设置。第四定位孔416优选为盲孔。
图23为本申请实施例提供的上壳体410与下壳体420的安装示意图。如图23所示，在上壳体410与下壳体420扣合状态下，由于第三密封胶条427高出第四边框顶面423，第三密封胶条427会受到第五边框顶面414的挤压而产生形变。形变后的第三密封胶条427会对与其接触的第四凹槽424的内壁和第五边框顶面414产生一定的压力，使得第三密封胶条427与第四凹槽424的内壁和第五边框顶面414紧密贴合，形成密封，阻止液体和灰尘从壳体外部进入到壳体内部。进一步地，由于第三密封胶条427包括两个朝着第五边框顶面414方向凸出的弧形结构，因此，在上壳体410与下壳体420扣合状态下，这两个弧形结构可以分别与第五边框顶面414紧密接触，从而使得第三密封胶条427与第五边框顶面414之间形成两道密封，提高防水防尘效果。
在一种实现方式中，电子设备还可以包括至少一个自身具备防水能力的连接器510，例如低速连接器。为便于设置连接器510，如图24所示，上壳体边框412可以设置有连接器开口417，连接器510可以设置于连接器开口417内。另外，为便于实现连接器510与上壳体410和下壳体420之间的防水，第三密封胶条427在连接器开口417处还设置 有与连接器510的结构匹配的环形结构428(见图22)，环形结构428套接在连接器510之上，并且在上壳体410和下壳体420扣合之后能够与上壳体边框412和下壳体边框422相接触，实现连接器510与上壳体410和下壳体420之间的防水防尘效果。
本申请实施例还提供了一种车辆，该车辆包括本申请上述各个实施例提供的电子设备，该电子设备可以包括车载计算模块，例如：自动驾驶计算平台、ECU、VCU等。其中，该车辆包括但不限于燃油机动车、油电混动机动车、纯电机动车、具备行驶能力的工程机械、自动导引车AGV、具备行驶能力的机器人等。
以上内容，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，任何在本申请揭露的技术范围内的变化或替换，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。
