背景技术
电子调速器是飞行器中的重要组成部件，能够起到控制飞行器中的电机转动状态，以实现飞行器的飞行控制和启停等操作。
因为飞行器常用于户外飞行，为了避免户外恶劣的环境，如雨、雾、湿气等飞行器中的电子调速器造成不良影响，电子调速器需要有密封防水结构。现有技术中，通常为了通入线缆，在电子调速器的上盒体和下盒体上分别开设有半圆形通孔，上盒体和下盒体盖合在一起后，两个半圆形通孔拼接成一个圆形孔，可供线缆从该圆形孔中穿入。同时，为了保证密封效果，通常在电子调速器的上盒体和下盒体的接缝处设置有环形的密封件，而在线缆与盒体的圆形孔之间也设有密封圈，环形的密封件和密封圈之间抵接在一起。
然而，为了保证密封性能，环形的密封件和密封圈一般均由可产生弹性形变的硅胶等软质材料构成，因而密封件和密封圈之间的接触部位会产生一定形变，导致产生变形或间隙过大等情况发生，影响电子调速器的整体密封性能。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明实施例一提供的电子调速器的爆炸示意图。图2是本发明实施例一提供的电子调速器在另一角度的爆炸示意图。请参照图1和图2，本实施例中的电子调速器100，能够连接在无人飞行器等设备的控制器和电机之间，以根据控制器所发出的控制信号，调整电机的转速，并进一步控制电机连接的螺旋桨等动力元件的转速，以控制无人飞行器进飞行姿态的调整和启停等操作。
如图1所示，本实施例提供的电子调速器100具体可包括控制电路板1、盒体,、线缆3和密封件4。其中，盒体为分体式结构，具体包括下盒体21和上盒体22，下盒体21和上盒体22内部均为具有开口的中空结构，且下盒体21的开口和上盒体22的开口相对，以共同围成一容置空间，这样，电子调速器100的控制电路板1等电子元件可设置在容置空间内，并 得到盒体的保护，用于连接电机、电源或者控制器的线缆3穿过盒体，并和盒体中的控制电路板1具有电性连接。
图3是本发明实施例一提供的下盒体的结构示意图。图4是本发明实施例一提供的密封件的结构示意图。请参照图3和图4，为了避免控制电路板1等电子元件受到外界环境的影响，盒体需要进行密封。为了保证盒体2的密封性，在下盒体21的侧壁上开设有容置槽211，且下盒体21的开口端面212上设置有环绕该开口的密封槽213，密封槽211的槽底和容置槽213的槽口边缘连通，线缆3穿设在容置槽211中，并与控制电路板1电连接，这样，密封件4可设置在容置槽211和密封槽213内,并由上盒体22压紧。通常的，构成密封件4的材料一般为硅胶或橡胶等材质构成，其具有一定的弹性。这样线缆3和下盒体21之间，以及上盒体22与下盒体22之间能够通过将密封件4压紧，并产生一定的弹性形变，而将盒体内部的间隙填满，起到密封作用。
其中，容置槽211贯穿下盒体21的侧壁，且容置槽211的顶端设有槽口，槽口一般延伸至下盒体21的开口端面212，从而让线缆3可由容置槽211的顶端槽口放入盒体之中。
由于密封槽213和容置槽211均设置在下盒体21上，所以在进行装配时，密封件4可以直接放入下盒体21的密封槽213和容置槽211内并进行装配固定，最后将上盒体22盖上压紧即可，由于密封件4先装配于下盒体22上进行准确的定位与固定，之后再直接盖上上盒体21压紧，这样位于密封槽213和容置槽211中的密封件4不会产生位移和较大形变，可以对密封件4与盒体之间的间隙进行良好的控制，保证盒体的密封性能。
具体的，由于密封槽213和容置槽211各自具有不同的形状，因而相应的，密封件4也包括有线缆密封件41和壳体密封件42，线缆密封件41设置在线缆3和容置槽211之间的空隙中，壳体密封件42设置在密封槽213内，且线缆密封件41和壳体密封件42之间具有接触面或连接面。在进行电子调速器100的装配时，线缆3可以先和线缆密封件41装配在一起，并穿设在下盒体21的容置槽211中，线缆密封件41与下盒体21的容置槽211之间进行固定密封后，再在密封槽213中设置壳体密封件42，从而完成上盒体21与下盒体22之间的密封。
为了保证对线缆密封件41进行良好的定位，同时加大线缆密封件41与壳体密封件42之间的接触面积，容置槽211的截面形状为矩形，且线缆密封件41的外缘形状与容置槽211的截面形状相匹配。这样线缆密封件41的外形和容置槽211的截面形状同为矩形或者方形，因而线缆密封件41在容置槽211内不会产生自转或滚动等姿态变化或位移，能够得到有效的定位和固定。同时，线缆密封件41的整个上缘均可实现与壳体密封件42之间保持接触，两者接触面积较大，壳体密封件42能够得到线缆密封件41的有效支撑，不会出现局部变形过大或者存在过大间隙的情况。
此外，需要说明的是，容置槽211的截面形状也可以为六角形等其它较易定位的形状，本实施例中并不加以限制。
进一步的，为了配合安装在线缆3上，在线缆密封件41上开设有可容线缆穿过的通孔411。通孔通常圆形，且孔径与线缆3的外径相匹配，线缆3穿过通孔411后，通孔411内壁会紧密贴合在线缆3外表面，从而保证线缆密封件41与线缆3之间能够紧密密封。
而为了保证线缆密封件41和下盒体21之间的定位与密封，线缆密封件41的外表面开设有定位卡槽412，定位卡槽412的两侧槽壁分别卡设在下盒体21的侧壁，从而夹在下壳体21侧壁的内外表面，以将线缆密封件41固定在下盒体21上。此时，线缆密封件41受到下盒体21侧壁的卡固作用而得以固定，同时，定位卡槽412与下盒体21之间的接触面形状较为复杂，也有利于线缆密封件41与下盒体21之间的密封。
进一步的，定位卡槽412可以延伸并环绕于线缆密封件41的外表面，这样容置槽211的边缘均会和定位卡槽412卡接，固定和密封效果更好，同时，壳体密封件42可卡设在定位卡槽412的靠近上盒体22一侧的槽段中，因而可被定位卡槽412定位在线缆密封件41的顶部位置。
在上述各实施方式的基础上，由于壳体密封件42需要对整个上盒体22与下盒体21之间的环形的结合面进行密封，所以壳体密封件42一般为密封圈。密封圈的形状为封闭的环形，能够对密封圈内侧和密封圈外侧进行有效隔离，避免外界水汽或者液体进入密封圈所围成的封闭形状内。具体的，密封圈的形状可以为矩形环状或者其它和上下盒体结合面的形状所适配的环状，此处不加以限制。
以下提供几种具体的实施方式，以对壳体密封件42与线缆密封件41之间的不同的连接方式进行详细说明。
作为一种可选的实施方式，线缆密封件41与壳体密封件42可以为抵接连接。由于构成密封件4的材料一般为硅胶或者橡胶等具有弹性的材料，所以可以先将穿设有线缆3的线缆密封件41装入下盒体21的容置槽211中，再将壳体密封件42固定在密封槽213内，最后将上盒体22盖设在下盒体21的开口端面212上。
此时，壳体密封件42的位于线缆密封件41上方的部位，与线缆密封件41之间通过上下盖体的挤压作用而紧密的抵接在一起，且壳体密封件42与线缆密封件41之间的接触面的面积因受压而增大，从而保证了对壳体密封件42与线缆密封件41之间接触面的密封。壳体密封件42和线缆密封件41的其余部分被挤向盒体侧壁，并实现了密封件4与上下盒体之间的密封。
上述壳体密封件42与线缆密封件41之间抵接连接，其装配工序较为简单，且线缆密封件41以及壳体密封件42能够分别准确的进行定位与固定，能够实现较好的密封效果。
作为另一种可选的实施方式，壳体密封件42还可由灌注在密封槽213和上盒体22之间空间内的密封胶凝固而形成。具体的，壳体密封件42并非是现成部件，而是在装配密封件的过程中，通过密封胶的凝固成型工序而构成的。
其中，当将线缆密封件41装入下盒体21的容置槽211中后，容置槽211的空间被线缆密封件41所弥补，封闭住密封槽213的原先与容置槽211连通的部位，使得密封槽213为封闭的凹槽。此时，即可向密封槽213中灌入密封胶，使密封胶均匀地填充在密封槽213之中；随后，可将上盒体22盖合在下盒体21的开口端面212上，并压紧密封槽213中的密封胶，使密封槽213与上盒体22之间共同围成一封闭空间。密封胶在该封闭空间中凝固并成型后，即可形成用于密封上下盒体的壳体密封件42。
通常的，灌注在密封槽213和上盒体22之间空间内的密封胶一般为硅胶材料。硅胶可以通过内部不同组分的调配，使之在一定时间内呈流体状态，并可灌入至密封槽213等狭窄的区域内。硅胶凝固成型后，即可保 持一定的弹性和吸附性，能够起到防水密封的效果。
此外，可选的，为了进一步对密封件4实现固定，并加强密封件4的密封效果，上述将壳体密封件42与线缆密封件41安装在盒体上之后，都可以在线缆密封件41和容置槽211之间，以及壳体密封件42和密封槽13之间均填充密封剂，以将密封件4粘接在盒体中，并填补密封件4与盒体之间的空隙。密封剂通常也可以为硅胶等材料。
在本发明提供的电子调速器中，由于线缆连接有电机和控制器等部件，所以线缆的数量为至少两条，并连接在电机或控制器的不同接线端上，相应的，此时容置槽的数量和线缆密封件的数量均可与线缆数量相同，并与线缆一一对应，即一条线缆上设有一个线缆密封件，并穿过一个容置槽中。
具体的，线缆3包括与电机连接的电机驱动线缆和用于供电的供电线缆，电机驱动线缆和供电线缆分别设置在盒体的两侧。由于电机一般为三相供电，所以电机驱动线缆一般有三条，而供电线缆通常包括有正极线缆和负极线缆两条。此外，线缆还可以包括用于和控制器相连，以传输控制信号的控制线缆。
图5是本发明实施例一提供的上盒体的结构示意图。请参考图5，电子调速器100的盒体中，上盒体22和下盒体21之间开口相对，并扣合在一起。由于密封槽213只设置在下盒体21上，因而上盒体22的开口端面221为和下盒体21的开口端面212平行的平面。上盒体22的开口端面221和下盒体21的开口端面212平行，能够在上下盒体盖合时紧密合拢，保证密封槽213的密封性能。
作为一种可选的实施方式，上盒体22的开口端面221上可设置有凸台222，凸台222的位置与密封槽213的位置相对应，以伸入密封槽213中。由于凸台222的存在，上盒体22与下盒体21在盖合时，上盒体22的凸台222可以伸入密封槽213内，以对上下盒体进行定位。为了使上盒体22和下盒体21之间紧密盖合，凸台222的高度应小于密封槽213的深度。这样凸台222会完全隐藏在密封槽213中，而上盒体22的开口端面221和下盒体21的开口端面212紧密贴合在一起。
凸台222伸入密封槽213中后，凸台222应该有足够的高度，并和位 于密封槽213中的密封件4抵接，以使密封件4为受压状态。密封件4受到凸台222的压力后，会产生弹性压缩形变，并填充在凸台222和密封槽213之间的空间内，形成密封结构。
此外，通常上盒体22和下盒体21之间可通过螺钉等紧固件连接。紧固件连接固定较为可靠，且便于拆卸。可以理解的是，上盒体22和下盒体21之间还可以通过卡合、胶粘等方式进行连接。
因为电子调速器100内部的控制电路板1上具有MOS管等发热元件，且控制电路板上的控制芯片等对温度较为敏感，为对电子调速器100内部进行有效散热，避免控制芯片等电子元件受到热量影响，上盒体22和下盒体21均为热传导速度较快的金属件。金属制成的上盒体22和下盒体21能够将盒体内的热量有效传导至外界，保证电子调速器100内的温度正常。
为了进一步加强散热，在上盒体22的至少部分外表面设置有散热鳍片223。一般的，散热鳍片223对应设置在盒体发热量较大的部位，或者可在盒体内部设置热管等导热件，并将导热件与散热鳍片223所在的部位相连接。
本实施例中，电子调速器包括控制电路板、盒体、线缆和密封件；盒体包括下盒体和上盒体，下盒体和上盒体内部均为具有开口的中空结构，且下盒体的开口和上盒体的开口相对，以共同围成一容置空间，控制电路板设置在容置空间内，下盒体的侧壁上开设有容置槽，且下盒体的开口端面上设置有环绕开口的密封槽，密封槽的槽底和容置槽的槽口边缘连通，线缆穿设在容置槽中，并与控制电路板电连接，密封件设置在容置槽和密封槽内,并由上盒体压紧。由于密封件先装配于下盒体上进行准确的定位与固定，之后再直接盖上上盒体压紧，这样位于密封槽和容置槽中的密封件不会产生位移和较大形变，可以对密封件与盒体之间的间隙进行良好的控制，保证盒体的密封性能。
在上述各实施方式的基础上，本发明还提供一种电子调速器的装配方法，该方法可以应用于如上所述的电子调速器中。图6是本发明实施例一提供的电子调速器的装配方法流程图。如图6所示，其方法具体包括：
S101、将穿有线缆的密封件卡设在电子调速器的下盒体的安置槽上。
其中，可先将线缆穿设在密封件上，具体的，可以将线缆穿设在线缆 密封件的通孔中，并将线缆密封件卡设在电子调速器下盒体的安置槽中，以完成线缆密封件的固定。
S102、在密封槽中灌入密封胶，以使凝固成型后的密封胶密封在密封槽和电子调速器上盒体之间的空间中。
由于线缆密封件、及下盒体的密封槽共同围成了一个封闭的槽体，所以可向该槽体中灌入密封胶，密封胶凝固成型后，即可密封在密封槽以及上盒体之间的空间内，完成整个电子调速器的密封。
本实施例中，电子调速器的装配方法具体包括先将穿有线缆的密封件卡设在电子调速器的下盒体的安置槽上，再在密封槽中灌入密封胶，以使凝固成型后的密封胶密封在密封槽和电子调速器上盒体之间的空间中。这样密封槽中的密封胶凝固成型后，即可密封在密封槽以及上盒体之间的空间内，完成整个电子调速器的密封。
在上述各个实施方式的基础上，本发明还提供一种无人飞行器，该无人飞行器中包括有如上所述的电子调速器和与电子调速器电连接的电机，电子调速器用于控制电机的转动。
具体的，电子调速器可在控制器的控制信号下控制电机按照不同的速度进行转动，从而改变和电机连接的螺旋桨的转速，以实现无人飞行器的启停和飞行姿态控制。电子调速器的具体结构及工作原理，已在前述实施例中进行了详细说明，此处不再赘述。
本实施例中，无人飞行器的电子调速器包括控制电路板、盒体、线缆和密封件；盒体包括下盒体和上盒体，下盒体和上盒体内部均为具有开口的中空结构，且下盒体的开口和上盒体的开口相对，以共同围成一容置空间，控制电路板设置在容置空间内，下盒体的侧壁上开设有容置槽，且下盒体的开口端面上设置有环绕开口的密封槽，密封槽的槽底和容置槽的槽口边缘连通，线缆穿设在容置槽中，并与控制电路板电连接，密封件设置在容置槽和密封槽内,并由上盒体压紧。由于密封件先装配于下盒体上进行准确的定位与固定，之后再直接盖上上盒体压紧，这样位于密封槽和容置槽中的密封件不会产生位移和较大形变，可以对密封件与盒体之间的间隙进行良好的控制，保证盒体的密封性能。
