如图2所示，其为本发明提供的遥控设备的结构示意图。遥控设备10包括显示屏1和遥控本体2。遥控本体2包括壳体40、设置在壳体40内的控制主板(未图示)、多个操作按钮、两摇杆30和保护锁机构20。显示屏1通过转轴11连接至壳体40，且所述显示屏1可绕转轴11转动。多个操作按钮、两摇杆30与控制主板电连接，用于控制无人飞行器的升降、飞行方向、飞行姿势等。两摇杆30相对壳体40可竖起或折叠放平。
保护锁机构20用于保护显示屏1，当显示屏1进行合屏动作时，此时，保护锁装置20处于第一状态(即常锁状态)，在显示屏1转过一定角度(该角度的范围跟摇杆30竖起时超出壳体40的高度、摇杆30与转轴11的直线距离相关，只要保证显示屏1在转过该角度后还未接触到摇杆30即可)时，保护锁机构20将锁住所述显示屏，阻挡显示屏1继续向下(向壳体40的方向)转动，提醒用户将摇杆30折叠放平，以防止竖起的摇杆30与显示屏1碰撞，损坏显示屏1。待用户折叠放平摇杆30后，再按下保护锁机构20的按键时，显示屏1才可继续往下转动，完成合屏动作。因此，保护锁机构20能够起到很好的防护作用。
以下详细说明本发明的保护锁机构20。
如图3a、图3b以及图4所示，图3a为本发明的保护锁机构处于常锁状态的立体示意图，图3b为图3a的俯视图，图4为本发明的保护锁机构的爆炸图。保护锁机构20包括连接转轴11的连接装置21、安装在壳体40内的转锁装置22、按键装置23和按键锁装置24。
连接装置21包括屏固定支架211和连接轴212。
屏固定支架211可为一垂直折弯件，其包括两相互垂直的直角臂，其中一直角臂的端部固定连接连接轴212，另一直角臂上设有两穿孔，两螺栓217穿过两穿孔将屏固定支架211固定在显示屏1的转轴11上。
进一步，在屏固定支架211的转轴11的外周边还设有另一屏固定支架，屏固定支架211与另一屏固定支架固定连接，藉此，屏固定支架211固定转轴11 上。在转轴11转动时，屏固定支架211跟随转轴11转动。
连接轴212从屏固定支架211处沿转轴11的轴向方向延伸。
连接装置21还包括第一凸起构件213和第二凸起构件214，该第一凸起构件213和第二凸起构件214可均为一独立的凸轮结构。第一凸起构件213和第二凸起构件214也可一体成型结构。无论是一体成型结构或为独立的凸轮结构，第一凸起构件213的凸起和第二凸起构件214的凸起相互错开，使得第一凸起构件213的凸起和第二凸起构件214的凸起能够在不同的时刻分别与转锁装置22和按键锁装置24配合，以使保护锁机构20能够在一定的时间长度内保持解锁状态。
第一凸起构件213、第二凸起构件214和转锁装置22的一端部(下文详细说明)套设连接轴212上，并通过组合压簧215和螺母216固定在连接轴212上。
连接轴212在屏固定支架211的转动下，做旋转运动，并带动固定在连接轴212上的第一凸起构件213和第二凸起构件214转动。
转锁装置22包括转锁固定支架221、转锁本体222和弹性连接件223。
转锁固定支架221包括底座和垂直于底座的主体部。两螺栓2216穿过底座的两穿孔将转锁固定支架221固定在壳体40上。转锁固定支架221的主体部靠近连接装置21的一端部设有第一卡勾2211，且该端部设有一供连接轴212穿过的穿孔2214。穿孔2214与连接轴212间隙配合，使得连接轴212转动时并不会带动转锁固定支架221转动。转锁固定支架221的主体部还设有两个用于与转锁本体222连接的椭圆形的长孔2212。
转锁本体222靠近连接装置21的一端部2221设有与第一凸起构件213配合的圆角滑动面2221a(如图5a所示)。转锁本体222远离连接装置21的另一端部2222设有折弯部，该折弯部上设有用于与按键装置23相配合的倾斜滑动面2222a。该另一端部2222上设有第二卡勾2224。端部2221和另一端部2222分别设有一穿孔2223。
两连接件2215分别穿过转锁固定支架221的两长孔2211和转锁本体222的两穿孔2223将转锁固定支架221和转锁本体222连接在一起。长孔2211与连接件2215为间隙配合，使得转锁本体222可相对于转锁固定支架221移动。
该连接件2215可为铆钉。
结合图4和图6所示，图6为清楚显示转锁固定支架和转锁本体通过弹性连接件连接的结构示意图。弹性连接件223的一端与转锁固定支架221的第一卡勾2211扣接，另一端与转锁本体222的第二卡勾2224扣接。转锁本体222通过弹性连接件223紧贴在转锁固定支架221上。
弹性连接件223可以是拉簧、压簧等弹性件。
继续参阅图4，按键装置23包括按键支架231、按键本体232和弹性压件233。
按键支架231包括阶梯状的底板2311，底板2311通过螺栓2314固定在壳体40上。底板2311包括上层底板2311a和下层底板2311b。下层底板2311a上设有用于安装按键本体232的安装墙2315，安装墙2315靠近下层底板2311b边缘的外侧突起一突块2312，该突块2312用于与按键本体232配合。安装墙2315围成一个半包围空间，在半包围空间内设置有一柱体2316。
按键本体232包括与按键支架231的安装墙2315相配合的侧部边缘2323设置在顶部的按键部2321以及由侧部边缘2323向下延伸的卡接延伸部2322。侧部边缘2323的中间设置该按键部2321，且按键部2321在外力的作用下可相对于侧部边缘2323上下移动。按键部2321包括由按键部2321的顶部向下延伸形成的按键凸起2324和卡接部2325(如图8a所示)，卡接部2325具有用于与按键锁装置24的第一突块相卡接的开口。
弹性压件233套设在按键支架231的柱体2316上，且被按键本体232压制在按键本体232的内腔中。当按键本体232受到外力作用时，按键本体232施加作用力在弹性压件233上，使弹性压件233向下压缩，当按键本体232的外力撤销时，弹性压件233产生恢复原状的弹力将按键本体232向上(向远离按键支架231的方向)弹起回位，即按键本体232恢复至常锁状态。
该弹性压件233可以是拉簧、压簧等弹性件。
按键本体232的侧部边缘2323与按键支架231的安装墙2315配合，按键支架231的突块2312穿过卡接延伸部2322的开口与按键本体232卡合连接。按键本体232的按键部2321可在按键本体232的内腔中相对于底板2311上下移动。
按键本体232的按键凸起2324位于转锁本体222的折弯部的内侧，在按键部2321受到外力向下移动时，按键凸起2324与转锁本体222的倾斜滑动面2222a 配合，并压迫折弯部带动转锁本体222向远离连接装置21的方向移动，使转锁本体222的端部2221的圆角滑动面2221a脱离第一凸起构件213的凸起滑动面2131(如图5b所示)。
按键锁装置24包括按键锁本体241和弹性推动件242。
按键锁本体241的中部设有一长孔2411，紧固件2415穿过长孔2411安装在按键支架231上。紧固件2415与长孔2411间隙配合，使得按键锁本体241可相对于按键支架231水平移动(即向远离或靠近连接装置21的方向移动)。
结合图4和图7所示，图7为清楚显示弹性推动件配合按键锁本体的结构示意图。按键锁本体241包括底面2416a和由底面2416a向上延伸的侧墙2416b。侧墙2416b位于按键锁本体241远离连接装置21的一端部。侧墙2416b上设有朝平行于底面2416a的方向延伸的凸起2417。凸起2417与底面2416a之间形成卡道2412，该卡道2412用于定位弹性推动件242。
按键支架231上设有支柱2313，弹性推动件242套设在支柱2313上。弹性推动件242的一端定位在卡道2412中，另一端自由延伸至按键支架231的下层底板2311b上。当按键本体232被施加外力时，按键部2321的侧部推动弹性推动件242旋转，使按键锁本体241向靠近按键本体232的方向移动，以锁住被按下的按键本体232。
弹性推动件242可以是扭簧或其他弹性件。
按键锁本体241的侧墙2416b向按键锁本体241的长度方向延伸出第一突块2413，第一突块2413用于与按键本体232的卡接部2325配合(如图8a所示)，当按键本体232在外力作用下，向下移动至预设位置时，第一突块2413与按键部2321的卡接部2325相卡接以锁住按键部2321，防止被按下的按键部2321在外力消失时，向上反弹。
按键锁本体241靠近连接装置21的一端向按键锁本体241的宽度方向延伸出第二突块2414。当保护按键锁20处于第二状态(即解锁状态)时，且当显示屏1转过预定角度时，第二突块2414与连接装置21的第二凸起构件214相接触，第二凸起构件214对第二突块2414作用，并拖动按键锁本体241向远离按键本体232的方向移动，使按键锁本体241的第一突块2413脱离按键本体232，保护锁装置20从第二状态切换至第三状态，第三状态为未恢复常锁状态的中间状态。
以下详细说明本发明的保护锁装置的工作过程和原理。
如图3a和图3b所示，保护锁装置20处于第一状态(常锁状态)时，按键装置23的按键本体232处于弹起状态，转锁装置22和按键锁装置24处于常锁状态。
如图5a所示，图5a为显示屏被阻止转动时保护锁机构的结构示意图，当显示屏1进行合屏时，向箭头A所指的第一方向旋转，即显示屏1向靠近壳体40的方向转动，当显示屏1旋转至一定角度时，连接装置21的第一凸起构件213的凸起滑动面2131碰触到转锁本体222的圆角滑动面2221a，圆角滑动面2221a阻挡第一凸起构件213继续转动，进而阻止显示屏1继续向第一方向旋转，显示屏1暂停合屏动作。
如图5b所示，图5b为显示屏被解除阻止转动时保护锁机构的结构示意图。当按键装置23的按键部2321在外力的作用下被按下而向下移动时，按键本体232的按键凸起2324与转锁本体222的倾斜滑动面2222a配合，并压迫折弯部带动转锁本体222向远离连接装置21的方向移动，使转锁本体222的端部2221的圆角滑动面2221a脱离第一凸起构件213的凸起滑动面2131。藉此，解除对第一凸轮构件213转动的阻止，进而解除对显示屏1转动的阻止，显示屏1可继续向第一方向旋转。
结合图7和图8a所示，图8a为按键锁装置锁住按键部的结构示意图，按键部2321在外力的作用下继续向下移动时，按键部2321的侧部推动弹性推动件242旋转，使按键锁本体241向靠近按键本体232的方向移动。当按键锁本体241移动至预设位置时，按键锁本体241的第一突块2413与按键部2321的卡接部2325相卡接以锁住按键部2321，防止被按下的按键部2321在外力消失时，向上反弹。此时，保护锁机构20处于解锁状态。
如图8b所示，图8b为第二凸起构件解锁按键锁装置和按键装置的结构示意图。当显示屏1被解除阻止转动时，继续转动，且当转动过预定的角度时，第二凸起构件214的凸起滑动面2141与按键锁本体241的第二突块2414相接触，第二凸起构件214的凸起滑动面2141对第二突块2414作用，并拖动按键锁本体241向远离按键本体232的方向移动，按键锁本体241的第一突块2413脱离按键部2321的卡接部2325，按键部2321解除锁定，在弹性压件233的作用下弹起，恢复至初始位置。保护锁装置20从第二状态切换回第三状态，即从 解锁状态切换至中间状态。
如图9a所示，图9a为按键锁装置恢复至常锁状态时的结构示意图。当显示屏1开屏时，向箭头B所指的第二方向旋转，第二凸起构件214向第二方向旋转，第二凸起构件214的凸起滑动面2141脱离按键锁本体241的第二突块2414，结合图7所示，按键锁本体241在弹性推动件242的作用下，恢复至常锁状态的位置。
结合图9b和图9c所示，图9b为转锁装置恢复至常锁状态时的截面示意图，图9c为转锁装置恢复至常锁状态时的立体结构示意图。显示屏1继续向第二方向旋转，第一凸起构件213向第二方向旋转，并压迫转锁本体222的端部2221，使转锁本体222向远离第一凸起构件213的方向移动，并在弹性连接件223的弹力作用下限制在常锁状态的位置。
藉此，保护锁装置20又恢复至常锁状态，当显示屏进行合屏时，又可对显示屏进行锁定。
此外，上述实施例对于按键装置的锁定是通过按键锁装置来实现的，但在另一个实施例中，可不需要设置按键锁装置，例如，可通过长按按键锁装置的方式使保护锁机构保持解锁状态一段时间，以留出足够的时间给用户转动显示屏。
本发明的遥控设备通过在壳体内设置保护锁装置，当显示屏进行合屏动作并转过一定角度时，锁住所述显示屏，阻挡显示屏继续转动，在保护锁装置受到外力的作用时，保护锁装置解除对显示屏阻挡，显示屏继续转动以完成合屏动作。本发明通过该保护锁机构提醒用户将遥控设备的摇杆折叠放平，藉此，避免显示屏进行合屏动作时碰撞未放平的摇杆而损坏显示屏。
可以理解，上述的遥控设备可以用于任一可以使用到遥控设备的应用场景，比如机器人控制、游戏机控制、无人飞行器控制等等，这里对其应用场景不作严格限定。
本发明还提供一种无人飞行器，包括飞行器本体和上述遥控设备，所述遥控设备用于控制所述飞行器本体飞行。
以上仅为本发明的较佳可行实施例，并非限制本发明的保护范围，凡运用本发明说明书及附图内容所作出的等效结构变化，均包含在本发明的保护范围内。
