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,所描述的实施例仅仅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做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。
下面结合附图,对本发明的箱盖、储液箱和无人飞行器进行详细说明。在不冲突的情况下,下述的实施例及实施方式中的特征可以相互组合。
实施例一
结合图1至图7,本发明实施例一提供一种储液箱200的箱盖30,该箱盖30可包括箍紧环1、盖体2以及密封结构4。其中,箍紧环1用于与储液箱200固定连接,具体的,储液箱200包括箱体10以及设于箱体10上的第一开口部20,箍紧环1与第一开口部20(即进液口)固定连接。本实施例的盖体2与箍紧环1配合,并且盖体2与箍紧环1形成一收容空间3。进一步的,盖体2还设有开口21,开口21与收容空间3相连通。密封结构4收容在收容空间3内,并且密封结构4与盖体2转动连接。
本实施例的密封结构4包括密封状态和打开状态。当密封结构4处于密封状态(此时箱盖30也处于密封状态)时,密封结构4在自身锁紧力作用下与开口21配合,以密封开口21,防止箱体10内的药液(或其他液体)溅出。
当密封结构4被施加压力时,密封结构4能够在收容空间3内相对盖体2转动至打开状态(此时箱盖30也处于打开状态),以打开开口21。本实施例的密封结构4能够在外部压力作用下,克服自身的锁紧力而相对盖体2转动至打开状态,从而使得开口21打开,无需手动打开箱盖30即可快速往箱体10内添加药液,提升药液添加的效率。
本实施例中,从密封结构4远离收容空间3的一侧对密封结构4施加压力,从而使得密封结构4从密封状态切换至打开状态。例如,当需要使用自动加药器为储液箱200添加药液时,可通过自动加药器水嘴顶持密封结构4远离收容空间3出一侧,当水嘴施加在密封结构4上的顶持力克服密封结构4的锁紧力时,密封结构4即在收容空间3内相对盖体2转动至打开状态,使得开口21打开,水嘴伸入开口21进入箱体10内而实现快速添加药液的功能,无需手动打开箱盖30。水嘴自动伸入开口21既不会使添加的药液洒落节约了成本,还有干净、卫生、环保的好处。
本实施例的盖体2大致呈圆形,开口21设于盖体2的中部或盖体2的其他位置。开口21可呈圆形、椭圆形或其他形状,密封结构4的形状、大小与开口21的形状、大小相适配。
所述密封结构4的具体结构可根据实际需求设计,例如,在图4至图7所示的实施例中,密封结构4可包括密封盖41以及用于将密封盖41连接至盖体2上的锁紧件42。具体地,锁紧件42具有锁紧力,密封盖41在锁紧件42的锁紧力作用下与开口21配合,以密封开口21。当密封盖41被施加压力时,密封盖41能够在收容空间3内相对盖体2转动至与开口21相分离,以打开盖体2。本实施例中,在箱盖30处于密封状态时,可从密封盖41远离收容空间3的一侧对密封盖41施加一顶持力,当这个顶持力足够大(顶持力能够克服锁紧件42的锁紧力)时,密封盖41会相对盖体2转动而与开口21分离,从而打开盖体2。在打开盖体2的过程中,可通过自动加药器的水嘴施加顶持力给密封盖41,节省了手动将箱盖30从箱体10拆卸的时间,提升了药液添加效率。
本实施例的密封盖41的形状、大小与开口21的形状、大小相适配。在一实施例中,密封盖41的大小与开口21的大小相等,密封盖41嵌设在开口21中。在另一实施例中,密封盖41稍大于开口21,密封盖41远离收容空间3的一侧抵接开口21的边缘。
当密封结构4处于密封状态时,密封盖41远离收容空间3的一侧与盖体2靠近开口21的区域抵接,
所述锁紧件42的具体结构也可根据实际需求设计,例如,在图4至图7所示的实施例中,锁紧件42可包括连接轴421和套设于连接轴421的扭簧422。本实施例的密封盖41通过连接轴421连接在盖体2上,扭簧422一端与盖体2配合,另一端与密封盖41配合。
结合图5和图7,盖体2设有安装部22,密封盖41设有连接部412,连接轴421穿设安装部22和连接部412,从而将密封盖41转动连接在盖体2上。具体的,连接部412包括第一连接部4121和第二连接部4122,安装部22设于第一连接部4121和第二连接部4122之间。连接轴421包第一端和第二端(图中未标出),第一端穿设安装部22后插接在第一连接部4121中,第二端穿设安装部22后插接在第二连接部4122中,扭簧422设于第一端和第二端之间,从而可通过第一连接部4121和第二连接部4122对扭簧422形成限位。
可选的,连接部412与密封盖41一体成型设置,或/和,安装部22与盖体2一体成型设置。
本实施例的密封盖41无论是处于密封状态,还是处于打开状态,扭簧422始终保持其一端与盖体2配合,另一端与密封盖41配合的状态。其中,扭簧422与盖体2、密封盖41的配合方式可根据需要设计,例如,在其中一实施例中,参见图8,扭簧422包括两个端部4221和设于两个端部4221之间的插接部4222,两个端部4221抵接盖体2朝向收容空间3的一侧,插接部4222与密封盖41插接配合。本实施例中,密封盖41包括插接槽,插接部4222与插接槽插接。在密封盖41相对盖体2转动的过程中,插接部4222与插接槽插接配合的方式,使得扭簧422不易与密封盖41分离,确保扭簧422始终对密封盖41施加一个锁紧力,在外部压力撤销后,密封盖41能够在锁紧力的作用下由打开状态恢复至密封状态。其中,插接槽设于第一连接部4121和第二连接部4122之间。当然,两个端部4221也可与盖体2朝向收容空间3的一侧插接配合,和/及,插接部4222也可与密封盖41抵接。
而在另一实施例中,扭簧422包括两个端部4221,其中一个端部4221与盖体2朝向收容空间3的一侧抵接或插接,另一个端部4221与密封盖41抵接或插接。
当然,本实施例的扭簧422可由其他具有锁紧力的弹性件来替代。
又结合图4至图7,所述密封结构4还可包括设于密封盖41的第一密封件43。当密封结构4处于密封状态时,第一密封件43与密封盖41朝向收容空间3的一侧配合,以密封开口21,防止箱体10内的药液从开口21与密封盖41的连接处漏出。本实施例的第一密封件43为密封圈,通过密封圈对开口21的四周进行密封,防止药液泄漏。此外,第一密封件43的材质可根据需要选择,如橡胶、硅胶等等。
第一密封件43与密封盖41的配合方式可根据需要设计,例如,在图9所示的实施例中,密封盖41稍大于开口21,密封盖41远离收容空间3的一侧的边缘设有凹 槽413,第一密封件43嵌设在凹槽413中。本实施例中,密封盖41通过第一密封件43抵接开口21的边缘,防止药液从密封盖41和开口21的连接处漏出。
在另一实施例中,密封盖41的大小与开口21的大小相等,第一密封件43套设于密封盖41的外边缘,密封盖41通过第一密封件43与开口21过盈配合,从而防止药液从密封盖41和开口21的连接处漏出。
结合图3至图9,密封盖41设有气孔411,密封结构4还包括设于密封盖41内的通气密封件44。在本实施例中,当储液箱200内的气压大于或者等于预设压强(该预设压强大于等于大气压强)时,通气密封件44用于密封气孔411,防止储液箱200内的药液通过气孔411外流。储液箱200内的药液从出液口流出后,会使得储液箱200内的气压逐渐减小当储液箱200内的气压减小至小于预设压强时,通气密封件44与气孔411相分离,以使储液箱200内的气压等于大气压强。
在本实施例中,通气密封件44包括旋钮441和设于旋钮441的密封垫442,本实施例的旋钮441与密封盖41固定连接。当储液箱200内的气压大于或者等于预设压强时,密封垫442用于密封气孔411。当储液箱200内的气压小于预设压强时,密封垫442与气孔411相分离,以使储液箱200内的气压逐渐增大至等于大气压强。具体的,当储液箱200内的药液量较多时,储液箱200内的气压大于或者等于预设压强,此时,密封垫442在储液箱200内的气压作用下(储液箱200内的气压作用在密封垫442上的作用力与图4所示的A方向相反)堵住气孔411,从而将气孔411密封,防止储液箱200内的药液通过气孔411外流。当储液箱200内的药液量逐渐从储液箱200的出液口流出,使得储液箱200内的气压逐渐减小时,外部大气压可以顶开密封垫442(外部大气压作用在密封垫442上的作用力为图4所示的A方向),使得密封垫442和气孔411分离,保持储液箱200内的气压与外部大气压一致,保持气压平衡,防止储液箱200内气压过低,药液难以流出。
其中,旋钮441与密封盖41固定连接的方式可根据需要设计,例如,在一实施例中,密封盖41内设有第一卡扣,旋钮441与第一卡扣卡接配合。而在其他实施例中,旋钮441可通过螺纹连接、插接等方式与密封盖41固定连接。
此外,箍紧环1与盖体2可一体成型设置,也可分体设置。当箍紧环1与盖体2分体设置时,盖体2连接在箍紧环1上。盖体2与箍紧环1的连接方式可根据需要选择,例如,在一实施例中,箱盖30还包括转轴6,盖体2通过转轴6转动连接在箍紧环1上,盖体2可相对箍紧环1转动而实现开合。而在其他实施例中,盖体2与箍紧环1可通过螺纹、扣接或其他方式连接。
箍紧环1与储液箱200的固定方式可根据需要选择,例如,在其中一实施例中,箍紧环1的内侧壁或外侧壁设有螺纹,用于与储液箱200固定连接(具体用于与第一开口部20固定连接)。在另一实施例中,箍紧环1的内侧壁或外侧壁设有卡扣,用于 与储液箱200固定连接(具体用于与第一开口部20固定连接)。
进一步的,结合图3至图7以及图10,所述箱盖30还包括设于箍紧环1上的锁紧机构,该锁紧机构的一端固定连接盖体2,以将盖体2锁定在箍紧环1上。该锁紧机构的另一端固定连接储液箱200,以将盖体2和箍紧环1锁定在储液箱200上。可选的,锁紧机构包括固定连接在箍紧环1外侧壁的锁紧部,盖体2设有第二卡扣,锁紧部与第二卡扣卡接配合。当然,锁紧机构与盖体2的配合方式并不限于卡接方式,也可采用螺钉8连接或者其他方式来件将锁紧机构与盖体2固定连接。此外,锁紧机构与储液箱200的连接方式可采用卡接、扣接或其他方式。
在本实施例中,锁紧部通过螺钉8固定连接在箍紧环1的外侧壁。可选的,所述箍紧环1的外侧壁设有第一凸出部和第二凸出部(图中未标出),螺钉8的一端与第一凸出部固定连接,另一端与第二凸出部固定连接,锁紧部与位于第一凸出部和第二凸出部之间的螺钉8部分固定连接。
此外,本实施例的箱盖30还包括设于盖体2朝向收容空间3的一侧的第二密封件5。当盖体2盖设在储液箱200的第一开口部20上时,第二密封件5用于密封第一开口部20,防止药液从第二开口部40与盖体2的连接处泄漏。
其中,第二密封件5与盖体2的配合方式可根据需要设计,例如,第二密封件5可嵌设在盖体2上,也可贴设在盖体2上。本实施例的第二密封件5为密封圈,通过密封圈对第一开口部20的四周进行密封,防止药液泄漏。此外,第二密封件5的材质可根据需要选择,如橡胶、硅胶等等。
实施例二
参见图1,本发明实施例二提供一种储液箱200,该储液箱200可包括箱体10、设于箱体10的第一开口部20以及箱盖30。其中,箱体10具有一储液腔,用于存储药液。第一开口部20与储液腔连通,本实施例的第一开口部20作为进液口使用。箱盖30的结构如图1至图10所示,具体可参见上述实施例一的描述,此处不再赘述。
在本实施例中,箱盖30的箍紧环1与第一开口部20固定连接。箍紧环1与第一开口部20的固定方式可根据需要选择,例如,在其中一实施例中,箍紧环1的内侧壁或外侧壁设有螺纹,第一开口部20的对应位置设有配合螺纹,箍紧环1的螺纹与第一开口部20的配合螺纹对应配合。
在另一实施例中,箍紧环1的内侧壁或外侧壁设有卡扣,第一开口部20的对应位置设有配合部,卡扣与配合扣接。
结合图1和图2,第一开口部20倾斜设于箱体10的顶部,方便箱盖30的连接。可选的,第一开口部20一体成型于箱体10的顶部。
进一步的,所述储液箱200还包括设于箱体10底部的第二开口部40,第二开 口部40与储液腔连通,本实施例的第二开口部40作为出液口使用。在本实施例中,当储液箱200内的药液量较多时,储液箱200内的气压大于或者等于预设压强,此时,密封垫442在储液箱200内的气压作用下(储液箱200内的气压作用在密封垫442上的作用力与图4所示的A方向相反)堵住气孔411,从而将气孔411密封,防止储液箱200内的药液通过气孔411外流。当储液箱200内的药液量逐渐从第二开口部40流出,使得储液箱200内的气压逐渐减小时,外部大气压可以顶开密封垫442(外部大气压作用在密封垫442上的作用力为图4所示的A方向),使得密封垫442和气孔411分离,保持储液箱200内的气压与外部大气压一致,保持气压平衡,防止储液箱200内气压过低,药液难以流出,从而确保储液腔内的药液排尽。
此外,在一些实施例中,所述储液箱200还包括设于箱体10上的把手部,方便用户拿取。可选的,把手一体成型于箱体10的顶部。
本实施例的储液箱200可搭载在可移动设备如无人车、无人飞行器上使用,也可单独使用。其中,储液箱200单独使用时,储液箱200是作为手持设备使用的。
