为了使本实用新型的目的、技术方案及优点更加清楚明白,以下结合附图1~5及实施例,对本实用新型进行进一步详细说明。应当理解,下文所描述的各实施例仅仅用以解释本实用新型,并不用于限定本实用新型。
作为本实用新型的一个目的,以下对本实用新型所提供的投影仪实施例做出详细说明,具体请参照图1至5,投影仪包括实现投影功能的投影仪本体10和对投影仪本体10进行不同俯仰角角度支撑的支撑部30,,支撑部30包括支撑件50,在支撑部30上设置插接端子42,该插接端子42可以是供电源线插接的电源端子或供数据存储器插接的数据端子,插接端子的数量可以根据实际需要而设置。在本实施例中,均以USB闪存盘(以下简称为U盘)作为数据存储器和USB接口作为插接端子42为例进行说明。投影仪还包括旋固机构(未图示),投影仪本体10和支撑部30通过旋固机构可旋转固定地相连接,需要说明的是,旋固机构例如可以采用将笔记本面盖保持不同开启角度并且开启保持力度可根据实际需要调整的旋固结构或者用于调节并固定台式显示器的显示角度的旋固结构来实现,也就是说,使两个部件可旋转固定地相连接的旋固机构属于本领域常用技术。投影仪本体10相对于支撑部30的旋转可使投影仪本体10的底面13与支撑件50贴合,以及可使投影仪本体10与支撑件50形成一定角度,例如投影仪本体10的底面13与整个支撑件50形成一定角度,该一定角度的大小满足投影仪的俯仰角调节范围的要求,从而支撑件50对投影仪本体10进行支撑,因此,在将投影仪本体10在俯仰角调节范围内旋转以获得期望的投影仪俯仰角时,插接端子42的位置相对于支撑件50始终保持固定,如此的话,无论投影仪本体10被旋转后所得到的投影仪俯仰角大小如何,插接端子42的位置都不受俯仰角变化的影响,从而插接端子42相对于用于支撑支撑件的支撑面的位置也不会变化,保证U盘60对插接端子42的***和拔出操作不受影响。可以理解的是,插接端子42可被认为是接口插接端子,而U盘60中设有插口插接端子,两端子插接耦合实现两者数据信号的通讯。
作为一种具体实施方式,支撑部30包括转接件40,支撑件50大体呈刚性的板状,通过板状的支撑件50实现支撑,由于板状支撑件50与支撑面面面接触地对投影仪本体10进行支撑,因此,投影仪本体10能获得稳定性高的支撑。可以理解的是,为实现相同功能,支撑件50可采用其他形状和结构,只需能起到刚性支撑功能即可。为实现刚性支撑功能,支撑件50为刚性体,刚性体为具有一定刚性的硬质材料,优选的,支撑件50的材质可采用常规的硬质塑料或者金属等。支撑件50与转接件40固定连接,例如,支撑件50和转接件40可以一体成型或者支撑件50通过焊接、卡接等方式与转接件40固定。插接端子42设置在转接件40上,投影仪本体10与转换件40通过旋固机构可旋转固定的连接。
进一步的,该投影仪本体10包括设有供镜头20投射光束的第一侧部11及与第一侧部11相对的第二侧部12,可知的是,相对于投影仪的投影面,第一侧部11位于投影仪的前侧,第二侧部12位于投影仪的后侧。转接件40与第二侧部12相邻并相连接,转接件40包括转接件本体41和设置在转接件本体41上的插接端子42,支撑件50由转接件40向接近第一侧部11的方向延伸。这样的话,在投影仪本体10以转接件40为中心旋转以调节镜头20的俯仰角时,插接端子42的位置始终保持不变,因此,对于U盘的使用不受影响。
优选的,上述旋固机构包括相连接的设置在转接件本体41上的第一旋固件和设置在投影仪本体10的第二旋固件,投影仪本体10绕第二旋固件相对于第一旋固件旋转并固定,第一旋固件和第二旋固件可采用相互配合的转轴和轴孔,且转轴在轴孔中的旋转位置可通过在两者之间增加阻尼系数或者阻尼部件来实现可旋转的固定。
进一步的,转接件本体41为一中空筒体,在筒体内部设置第一旋固件,插接端子42由筒体的表面的开口43朝向筒体内部延伸,用户可通过开口43将U盘60***插接端子42或从插接端子42拔出U盘60。优选的,转接件本体41采用与支撑件50相同的刚性的硬质材料。
较佳的是,插接端子42的延伸方向与支撑件50的延伸方向平行,可知的是,一般的,由于支撑件50整体地与水平支撑面相接触以将投影仪本体10支撑在水平支撑面上,因此,插接端子42的延伸方向一般为水平方向,这样的话,便于用户平稳地施加对U盘相对于插接端子42***或拔出的作用力,也使得投影仪整体外观美观,而且插接端子42与水平支撑面之间保持一定的间距,在U盘60的***和拔出及使用过程中,U盘60都不会与支撑面产生碰撞或干涉,保障投影仪的良好使用。此外,插接端子42也可以沿远离支撑件50的方向延伸,则用户可相对于支撑面倾斜地插接U盘60,施力相对更方便些。
为了使投影仪整体结构紧凑,占用空间小,进一步的,投影仪本体10的第二侧部12相对于第一侧部11设有一预置缺口15,支撑部30布置于预置缺口15中,从而第二侧部12和支撑部30的组合与第一侧部11相对平齐,第一旋固件和第二旋固件分别设置在相对的第二侧部12的和转接件本体41的自由端处。
作为进一步改进,为了提高支撑件50支撑投影仪本体10的支撑稳定性,支撑件50设为长方形板,且支撑件50在平行于第二侧部12延伸方向上的宽度大于等于第二侧部12延伸长度的三分之一,支撑件50在垂直于第二侧部12延伸方向上的长度大于等于第一侧部11和第二侧部12之间距离的二分之一。
较佳的,投影仪本体10的底面13上设有凹槽14,凹槽14的形状与支撑件50的形状相适配,且凹槽14可容纳支撑件50于其中。这样的话,当支撑件50被容纳于凹槽14中时,可减少投影仪占用空间,便于投影仪的储存和携带。
需要补充说明的是,对于以上所述的投影仪本体10和插接端子42,两者通过在投影仪本体10和转接件40的内部布置的线缆来电连接,具体来说,在转接件本体41和投影仪本体10上开设有相应的开孔以供线缆经过,设置在投影仪本体10中的电路板接收来自插接端子42的电能或/和数据信号,从而实现投影仪的正常工作。
进一步来说,转接件本体41远离第二侧部12的自由端端面设置标志件70,在投影仪本体10被旋转以调节投影仪的俯仰角时,标志件70相对于被旋转的投影仪本体10的位置不变并始终保持处于期望展示的位置。因此,借助在不受俯仰角调节影响的转接件本体41的面向观察者的自由端端面设置例如商标、品牌等标志件70,提升了投影仪的可辨识性。
以下对作为旋固机构的一个具体实施方式进行进一步说明,转接件本体41上的第一旋固件包括一转轴,转轴固定在转接件本体41的筒体内部的中心位置,比如,转轴可以卡接固定在筒体内部的一个轴孔中,优选的,转轴在筒体内部向着第二侧部12延伸且延伸至该筒体之外,投影仪本体10的第二旋固件包括中空的连接套,连接套可以通过在第二侧部12面向支撑部30的一侧开设凹孔,并将连接套固定在该凹孔中,连接套与转轴同轴正对,连接套用于与转轴的延伸出的端部连接,从而转轴插接于连接套内。在转轴外壁上形成有多个卡齿,并且连接套内壁上形成有多个卡槽;优选的,卡齿沿转轴轴向延伸,并且其表面为弧形;连接套内壁上分布有多个沿连接套轴向延伸的限位凸起,限位凸起表面为弧形;相邻两个限位凸起之间形成与卡齿相配合的卡槽。多个限位凸起即形成多个上述卡槽。连接套套设于转轴的端部。卡齿配合设置于连接套的卡槽内。卡槽对卡齿进行限位,从而对转轴的转动起到一定的阻碍作用。当驱动连接套相对转轴转动的力达到一定程度后,表面为弧形的卡齿可克服上述卡槽的限位作用,从卡槽内滑出,并沿弧形的限位凸起表面移动到相邻的卡槽内,从而实现支撑部40与投影仪本体10相对角度的调整,如需继续调整,只需继续转动转轴即可,直至调整至合适角度即可。此时,通过卡齿和卡槽的配合限位作用,使投影仪本体10的位置固定,从而实现对投影仪本体10相对于支撑件50的角度调节及固定。更具体来说,在调节投影仪的俯仰角角度时,用户的一只手抓握固定住支撑件50或者将支撑件50的板平面压贴在支撑面上,用户的另一只手操作投影仪本体10使连接套相对于转轴、并克服卡齿和卡槽之间的阻尼而旋转,直至旋转到期望的俯仰角角度,此时,卡齿和卡槽之间的阻尼防止投影仪本体10的转动即防止俯仰角角度改变,该俯仰角角度可以理解的是支撑件50所在平面与投影仪本体10所在平面之间的夹角。另外,卡齿和卡槽之间的阻尼系数大小可以通过对卡齿和卡槽接触面的接触面大小和接触面摩擦系数的设计来获得。另外,以上以支撑部30包括的转轴和投影仪本体10包括的连接套可旋转固定地配合进行了说明,可替换的是,也可以是支撑部30包括连接套和投影仪本体10包括转轴。
上述投影仪中,用于调节投影角度的支撑件50位于投影仪本体10的底面13以下,通过投影仪本体10设置的连接套与固定连接有支撑件50的支撑部30所设置的转轴配合,从而达到使用效果。使用时,将支撑件50保持与支撑面接触的同时将投影仪本体10相对于支撑部30旋转使得投影仪本体10上的镜头20与支撑面形成理想的俯仰角角度,并且***插接端子42的U盘60始终保持大致水平状态,此时镜头20将投影画面投放到理想的区域。
当使用完毕,可旋转投影仪本体10使得支撑件50容纳于投影仪本体10底面13上设有的凹槽14之中,便于对投影仪的储藏和携带。
本实施例所提供的投影仪的用于调节俯仰角角度的结构是简单的,可稳定、较大角度地调节俯仰角,而且俯仰角的变化不会对插接端子42的操作产生不利影响,保证投影仪的正常工作。
