 本发明的最佳实施方式
应当理解，此处所描述的具体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 。
本 实用新型 提供一种投影仪，参见图 1 至图 3 ，在一实施例中，该投影仪包括壳体 100 和置于壳体 100 内的机体（图未示），壳体 100 上开设有对应于机体的镜头的镜头孔 110 ，其中机体包括诸如控制板、光源及镜头等零部件，用于将接收的信号源转换为对应的图像并投影在屏幕上，有关机体的结构组成和工作原理已为本领域的技术人员所熟知，在此不作赘述。
此外，本实施例的壳体 100 上通过一连接机构连接有一支承件 200 ，其中支承件 200 是枢接于壳体 100 的，在连接机构的限位下可在第一位置和第二位置之间转换。优选地，支承件 200 的转动轴线与镜头孔 110 的轴线平行，同时应当理解，支承件 200 的转动轴线与镜头孔 110 的轴线分开一定距离，通过旋转支承件 200 以选择性地遮蔽该镜头孔 110 ，当然，支承件 200 也可以远离镜头孔 110 ，在实际应用时仅起到支撑作用。连接机构用于给支承件 200 提供定位在预设位置的作用力，也就是说支承件 200 只有在受到外力作用下才发生旋转，以保证支承件 200 实现支撑功能的可靠性。当支承件 200 转动至第一位置时，支承件 200 与壳体 100 的一表面贴合，同时触发一投影元件使得机体处于第一工作状态；当支承件 200 转动至第二位置时，支承件 200 离开壳体 100 的表面并带动壳体 100 改变其相对于水平面（比如放置投影仪的工作台面）的投影仰角，同时触发该投影元件使得机体处于第二工作状态。需要说明的是，第一工作状态与第二工作状态相对立，比如第一工作状态可以是不投影状态，而第二工作状态为投影状态；或者第一工作状态为电源断电状态，而第二工作状态为电源供电状态，等等，在此不一一列举。通过将支承件 200 的位置与机体的工作状态关联在一起，以实现集多种功能于一体的结构，可以大大减小投影仪的体积，同时具有更加便捷的操作方式。
优选地，投影元件为镜头孔 110 ，支承件 200 在第一位置时遮蔽该镜头孔 110 ，此时机体的第一工作状态为不投影状态；支承件 200 在第二位置时离开镜头孔 110 ，此时机体的第二工作状态为投影状态。支承件 200 将镜头孔 110 遮蔽，一方面触发机体，使其关闭投影，另一方面 防止外界空气中的颗粒物积存在机体的镜头上；支承件 200 远离镜头孔 110 ，以使镜头孔 110 与外界相通，机体的镜头可以正常出光，并且支承件 200 远离其转动轴线的一端可用于将投影仪的前端悬空撑起，以调节投影仪的投影角度。
这里需要说明的是，上述第一位置指的是支承件 200 能将镜头孔 110 完全遮蔽的任意位置，第二位置指的是支承件 200 完全离开镜头孔 110 ，并且支承件 200 远离其转动轴线的一端能伸出至投影仪的底部下方的任意位置，支承件 200 在第一位置时主要起到遮蔽镜头孔 110 的作用，而在第二位置时主要起到支撑起投影仪的前端的作用。
基于上述技术方案，当不使用投影仪时，将支承件 200 旋转至第一位置，此时支承件 200 收回至与壳体 100 的表面重合的位置，不占用投影仪的厚度，并将镜头孔 110 遮蔽，将投影仪切换至不投影状态，同时防止外界空气中的颗粒物积存在机体的镜头上；当使用投影仪时，将支承件 200 旋转至第二位置，此时支承件 200 远离镜头孔 110 ，并且支承件 200 远离其转动轴线的一端伸出至壳体 100 的底部下方将投影仪的前端悬空撑起，以调节投影仪的投影角度，由此将镜头盖与支撑脚一体化，在实现投影角度自由调节的前提下减小了整机厚度，可以适应超薄机型的结构设计，同时有利于降低包装成本。
优选地，投影元件为电源控制装置，支承件 200 在第一位置时使得电源控制装置关闭，此时机体的第一工作状态为电源断电状态；支承件 200 在第二位置时使得电源控制装置接通，机体的第二工作状态为电源供电状态。由此，本实施例的支承件 200 还兼用作投影仪的电源开关，并且这种联动控制方式的操作更加便捷，同时有利于节省电能。
又或者，投影元件包括镜头孔 110 和电源控制装置，二者均位于支承件 200 的第一位置上。支承件 200 在第一位置时遮蔽镜头孔 110 ，同时使得电源控制装置关闭，机体的第一工作状态为电源断电状态；支承件 200 在第二位置时离开镜头孔 110 ，同时使得电源控制装置接通，机体的第二工作状态为开启投影的电源供电状态。
具体应用时，可将支承件 200 对电源控制装置的控制方式分为两种，分别是非接触式控制和接触式控制。结合图 3 ，在一实施例中，电源控制装置为光感应开关 600 ，即支承件 200 采用非接触式控制，光感应开关 600 的光接收元件显露于壳体 100 的外侧，比如将光感应开关 600 固定在壳体 100 的内侧，并且壳体 100 上对应于支承件 200 的位置开设有供光接收元件显露出的通孔，当支承件 200 转动至第一位置时，支承件 200 将光接收元件遮蔽，此时光接收元件受到的光照亮度降低至使光感应开关 600 处于断路状态，由此断开机体的供电电源；当支承件 200 转动至第二位置时，支承件 200 远离光接收元件，以使光接收元件敞露，此时光接收元件受到的光照亮度升高至使光感应开关 600 处于导通状态，由此接通机体的供电电源。例如，这里的光接收元件可以为光敏电阻，入射光强，电阻减小，将控制电路导通；入射光弱，电阻增大，将控制电路断开。
在另一实施例中，电源控制装置为机械开关（图未示），即支承件 200 采用接触式控制，其中机械开关可以是微动开关、按压式开关等其他任意适用的电源开关，该机械开关具有突出于壳体 100 的外侧的受压控制部，该受压控制部与支承件 200 滑动接触的部分可以形成为楔形面，或者受压控制部突出于壳体 100 的外侧的部分形成为半球状，当支承件 200 转动至第一位置时，支承件 200 压接于受压控制部，以触发机械开关断开机体的供电电源；当支承件 200 转动至第二位置时，支承件 200 远离受压控制部，以释放受压控制部，应当理解，受压控制部与一弹性件连接，在支承件 200 解除对受压控制部的压接作用时，受压控制部在弹性回复力的作用下复位，触发机械开关接通机体的供电电源。相较于上述非接触式控制，本实施例的机械开关具有更高的可靠性，比如不受环境光照的影响。
值得一提的是，除了使用上述光感应开关 600 和机械开关，还可以采用接近开关作为电源控制装置，比如电容式接近开关和电感式接近开关等。
本实施例中，为了方便机体的安装拆卸，大体上可将壳体 100 拆分为两部分，比如相结合的上盖和底壳，其中上盖可以被构造成一平板结构，底壳具有一底面和自该底面的周边往垂直于该底面的方向延伸的侧面，上盖与底壳之间可通过卡扣结构或螺钉连接。作为示例之一，壳体 100 大致呈扁平长方体或扁平正方体，并且壳体 100 的左右两侧均为圆弧过渡，以使壳体 100 整体外形美观。根据附图所示壳体 100 的实施结构，底壳的侧面朝向上盖延伸，具体可分为前后侧面和左右侧面，其中镜头孔 110 和支承件 200 位于底壳的前侧面上，支承件 200 的转动轴线可以垂直于底壳的前侧面，当然也可以平行于底壳的前侧面。具体地，当支承件 200 的转动轴线垂直于底壳的前侧面时，支承件 200 可以在底壳的前侧面上作 360 °或小于 360 °旋转；当支承件 200 的转动轴线平行于底壳的前侧面时，支承件 200 可以上下翻转。
于较佳实施方式中，支承件 200 为一体成型的单一零件结构，从而结构简单，更适合于微型投影仪的结构和尺寸需要；另外，采用单一零件结构，可避免因多零件构成而增多失效因素，影响支承件 200 的使用寿命；而该单一零件结构也更容易更换和修复，降低成本。
支承件 200 的形状比如为板状结构，也可以为杆状结构或其他任意适用的曲面状结构，具体应用时可随壳体 100 的外观结构作适应性改变，本实用新型对此不作限制。例如，为了适应本实施例中壳体 100 的外观形状，支承件 200 优选为平板状结构，并且在长度方向上的两端面倒圆角，即整体外形类似于腰形，当支承件 200 转动至第一位置时，支承件 200 能够与底壳的前侧面完全重合，不占用空间且使得壳体 100 的外形美观简洁。对于支承件 200 的转动轴线的具体设置位置，应当以支承件 200 转动至第一位置时能将镜头孔 110 完全遮蔽，而在支承件 200 转动至第二位置时能将投影仪平稳地支撑起为宜，比如本实施例的支承件 200 的转动轴线稍微偏离于壳体 100 在宽度方向上的中部，有利于实现投影仰角的调节。
进一步地，为了方便用户操作，支承件 200 上设置有操作部（图未示），通过该操作部接收用户施加的作用力，以使支承件 200 在第一位置与第二位置之间转动。例如，该操作部为自支承件 200 背对壳体 100 的一面向内凹入的凹位，或者操作部为自支承件 200 背对壳体 100 的一面向外突出的凸起。另外，支承件 200 远离其转动轴线的一端的端面设置防滑结构，该防滑结构具有多种实现方式，比如细条状的凹槽或凸起，或者粘接在支承件 200 上的软质胶层，当支承件 200 转动至第二位置时，远离其转动轴线的一端的端面为支撑面，由此可通过防滑结构增大支撑面的摩擦力，确保投影仪平稳地放置在工作台面上。
本实施例中，连接机构为枢轴机构，以使支承件可绕一转轴在机壳上转动或摆动，并且转动或摆动角度可灵活设置，比如可连续旋转 360 °，当然也可以小于 360 °，该枢轴机构可以是轴孔静摩擦配合、轴承配合、齿轮配合、链带配合等若干方式中一种。在可选实施方式中，所述连接机构包括转轴、与该转轴配合的轴孔以及设置在转轴上的限位件，通过该限位件对转轴相对于轴孔的转动形成限制，该限制可以是提供足够大的阻尼、单向旋转等。
作为示例，结合图 3 ，转轴 210 设置在支承件 200 上，轴孔 120 开设在壳体 100 上，转轴 210 插装在轴孔 120 中，比如限位件可以是带有足够阻尼的轴套，也可以是本优选方案中的单向轴承 300 。另外，还需说明的是，转轴 210 还可以与轴孔 120 对调。转轴 210 设置在支承件 200 面对壳体 100 的一面上，转轴 210 开设有自其端面向内凹入的螺纹孔，壳体 100 的内侧设置有对应于轴孔 120 并用于容置单向轴承 300 的轴承座 130 ，轴承座 130 可与壳体 100 一体成型，也可以分别成型之后固定在一起，轴承座 130 的一面敞开并通过一可拆卸地连接于轴承座 130 的轴承压板 131 将该敞开的一面遮盖，比如本实施例的轴承座 130 大致呈方形，并且其面对上盖的一面敞开设置，轴承压板 131 通过螺钉固定于轴承座 130 。具体装配时，单向轴承 300 套在转轴 210 上并置于轴承座 130 中，通过旋入螺纹孔中的螺钉 500 将单向轴承 300 的内圈与转轴 210 紧固，再通过轴承压板 131 将单向轴承 300 的外圈固定，使得单向轴承 300 的外圈不能随转轴 210 转动。由此，单向轴承 300 在本实施例中主要起到两方面的作用，一方面是给支承件 200 提供稳定的支撑，使支承件 200 平稳地绕着特定的转动轴线旋转；另一方面是给支承件 200 提供定位在预设位置的作用力，即支承件 200 只能按顺时针或逆时针旋转，满足定位要求。
为了防止因转轴 210 与单向轴承 300 之间产生滑动而使支承件 200 的单向转动功能失效，本实施例的连接机构还包括呈弹性压缩地设置在单向轴承 300 与螺钉 500 之间的波纹垫圈 400 ，通过波纹垫圈 400 产生的弹性回复力将转轴 210 与单向轴承 300 的内圈牢靠地固定在一起，起到防松作用。而在其他实施例中，还可以通过在转轴 210 与单向轴承 300 的内圈之间设置键来替代波纹垫圈 400 ，当然也可以将波纹垫圈 400 和键结合使用。
为了实现支承件 200 的旋转定位功能，连接机构还可以由其他部件组成，例如本实施例的连接机构包括棘轮和与该棘轮相配合的棘爪（图未示），通过由棘轮和棘爪组成的棘轮机构限制支承件 200 作单方向旋转。其中棘轮套在转轴 210 上，也可以通过旋入转轴 210 的螺纹孔中的螺钉将棘轮与转轴 210 紧固，从而限制棘轮与转轴 210 之间的相对转动，而棘爪设置在壳体 100 的内侧并与棘轮相配合。相较于采用单向轴承 300 的技术方案，本实施例的整体结构稍加复杂，但是能够很好地给支承件 200 提供保持在预设位置的作用力。值得一提的是，连接机构还可以是阻尼器，通过给支承件 200 提供足够的扭转阻尼，以使支承件 200 在将投影仪悬空撑起时保持不动，相较于文中指出的两种连接机构，支承件 200 可以实现无级调节功能，投影仪的投影角度调节精度更高。
以上仅为 本 实用新型 的优选实施例，并非因此限制本 实用新型 的专利范围，凡是利用本 实用新型 说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本 实用新型 的专利保护范围内。
