Description

一种投影机和投影机开关控制方法 技术领域
本申请涉及投影机技术领域，特别涉及一种投影机和投影机开关控制方法。
背景技术
控制投影开关机的方法均存在误触发问题，特别是便携产品，自身带有电池供电，用户放在包内等狭小空间下，例如包内物品互相摩擦、挤压，容易触发开机，对于投影来说，包内扇热环境不良，开机不仅浪费电量，还存在安全隐患，出于安全角度考虑，异常开机的情况必然需要考虑。相关技术中利用按键触发或遥控器控制投影机开关，按键容易在包内被按下触发，无法避免；若增加防呆设计，如，连续两次按键触发或长按按键触发开机，虽然能解决该问题，但是，正常使用情况下，用户体验差。
因此，如何提供一种解决上述技术问题的方案是本领域技术人员目前需要解决的问题。

附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。

图3为本申请实施例所提供的另一种投影机的结构示意图；
图4为本申请实施例所提供的另一种投影机的结构示意图；
图5为本申请实施例所提供的一种投影机开关控制方法的流程示意图。
具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
相关技术中利用按键触发或遥控器控制投影机开关，按键容易在包内被按下触发，无法避免；若增加防呆设计，如，连续两次按键触发或长按按键触发开机，虽然能解决该问题，但是，正常使用情况下，用户体验差。基于上述技术问题，本实施例提供一种投影机，具体请参考图1，图1为本申请实施例所提供的一种投影机的结构示意图，具体包括：
投影机舱体100；在投影机舱体100的一端设置有光机镜头200；设置在光机镜头200前方的滑盖300；目标传感器400，用于采集光机镜头200一端和投影机舱体100的远离光机镜头200的一端的信号；与目标传感器400连 接的驱动主板500，用于根据信号控制投影机的工作状态，工作状态包括开机状态和关机状态。
在已有的产品中，通过滑盖控制开关机的设计，存在用户反馈在包内由于摩擦挤压原因，在包内开机的问题，一方面浪费电量，造成了较差的用户体验；另一方面，在包内开机，扇热环境不良，容易对投影本身造成伤害，温度过高甚至会有火灾的隐患。所以目前基于滑盖设计的产品，为避免次问题，多增加滑盖滑动的力度解决次问题，但也带来了不良的体验，用户需要用较大的力量才能滑动滑盖开机。
针对投影机舱体100本实施例进行进一步阐述，本实施例中不对投影机舱体100的大小、材质、形状进行限定，用户可根据实际需求进行设置。可以理解的是投影机舱体100包括迷你投影机对应的舱体和常规投影机对应的舱体。
本实施例中不对光机镜头200进行限定，一般的，光机镜头200设置在投影机舱体100的一端。
在本实施例中，设置有滑盖300，滑盖300设置在光机镜头200前方，投影机舱体100与滑盖300对应的位置设置有滑槽，以便滑盖300可以在光机镜头200前滑动，一方面可以通过目标传感器400定位滑盖300的位置确定开关机状态，另一方面，滑盖300还可以保护光机镜头200不被磨损。
针对目标传感器400进行进一步阐述，本实施例不对目标传感器400进行限定，可以是压力传感器还可以是红外传感器或者TOF传感器，只要是能够获得光机镜头200一端和投影机舱体100的远离光机镜头200的一端的信号即可，采集的方式可以是直接获取还可以是间接获取，只要是能够实现本实施例的目的即可。值得注意的是，针对不同类型的目标传感器400，目标传感器400再投影机舱体100内的与光机镜头200设置的相对位置存在不同。
驱动主板500，用于根据信号控制投影机的工作状态，工作状态包括开机状态和关机状态。
基于上述技术方案，本实施例通过设置目标传感器400与滑盖300结合的方式控制工作状态，目标传感器400采集到光机镜头200一端和投影机舱体100的远离光机镜头200的一端的信号，当滑盖300在远离光机镜头200的一端时得到一种信号，在滑盖300在光机镜头200一端时得到另一种信号，以使驱动主 板500根据该信号控制工作状态，极大地减少了误触现象的发生，提高了用户体验。
基于上述实施例，本实施例提供另一种投影机，请参考图2，图2为本申请实施例提供的另一种投影机正视的示意图，其中，目标传感器400为测距传感器，包括三个组件，其中，任意两个组件400-1、400-2分别设置在光机镜头200的两端的预设范围内，最后一个组件400-3设置在投影机舱体100的远离光机镜头200的一端，三个组件为信号发射管、第一信号接收管和第二信号接收管；驱动主板500，用于当信号发射管发射预设信号时，根据检测到的第一信号接收管与第二信号接收管接收的预设信号控制工作状态。
可以理解的是，本实施例中不对第一信号接收管和第二信号接收管进行限定，两者可以相互替换，例如，在一种可实现的实施方式中，第一信号接收管可以是信号接收管a，第二信号接收管可以是信号接收管b；在另一种可实现的实施方式中，第一信号接收管可以是信号接收管b，第二信号接收管可以是信号接收管a。
本实施例中，驱动主板500根据检测到的第一信号接收管与第二信号接收管接收到的预设信号控制工作状态，在一种可实现的实施方式中，该预设信号是是否存在有效信号，也即根据是否接收到第一信号接收管和第二信号接收管的预设信号来控制工作状态，在另一种，可实现的实施方式中，该预设信号是距离信号，根据第一信号接收管和第二接收管的距离信号对应的距离值判断是否是在小空间内，若在小空间内，均为误触，则控制工作状态为关机状态，若不在小空间内，则根据第一信号接收管和第二接收管是否接收到距离信号判断是关机状态还是开机状态。当然，可能还存在其他形式，本实施例不再进行赘述。
可以理解的是，本实施例提供的投影机包括投影仪舱体100、光机镜头200、驱动主板500，当然还包括扇热系统，功放系统等。在光机镜头100前方放置滑盖，一方面可以控制滑盖300的滑动，控制开机，另一方面可以通过滑盖对光机镜头200起到一定的保护作用。在本方案中，滑盖设计和TOF测距传感器配合控制投影的开关机状态。其中TOF测距传感器包括一个信号发射管和两个信号接收管；TOF器件的初始化、工作模式切换、数据读取通 过驱动主板500上的相关功能模块完成。其中，TOF测距是利用数据信号在一对收发机之间往返的飞行时间来测量两点间的距离。将发射端发出数据信号和接收到接收端应答信号的时间间隔记为Tt，接收端收到发射端的数据信号和发出应答信号的时间间隔记为Tr。信号在这对收发机之间的单向飞行时间Tf＝(Tt-Tr)/2，则两点间的距离d＝c*Tf，其中c表示电磁波传播速度。本专利利用该技术进行距离数据的测量。
本实施例中，信号发射管包括但是不限定于红外发射器、激光发射器、毫米波雷达发射器。本申请中不对预设范围进行限定，只要是在光机镜头200的两端的近距离即可，可以是1cm、3cm、5cm或者其他距离只要是能够实现本实施例的目的即可。
在一种可实现的实施方式中信号发射管与第一信号接收管分别设置在光机镜头200的两端的预设范围内，第二信号接收管设置在投影机舱体100的远离光机镜头200的一端；对应的，驱动主板500，用于当信号发射管发射预设信号时，若检测到第一信号接收管接收到预设信号，且第二信号接收管未接收到预设信号，则控制投影机为开机状态；若检测到第一信号接收管未接收到预设信号，则控制投影机为关机状态。在一种可实现的实施方式中，滑盖的长度小于第二信号接收管与第二信号接收管水平距离最近的组件之间对应的距离。在另一种可实现的实施方式中，滑盖的长度等于第二信号接收管与第二信号接收管水平距离最近的组件之间对应的距离。
上述存在两种方式，第一种，信号发射管与第一信号接收管分别设置在光机镜头200的两端的预设范围内，其中，第一信号接收管设置在光机镜头200近投影机舱体100的一端，第二信号接收管设置在投影机舱体100的远离光机镜头200的一端。例如，400-2是信号发射管，400-1为第一信号接收管，400-3为第二信号接收管，此时，当驱动主板500检测到第一信号接收管接收到预设信号，且第二信号接收管未接收到预设信号，则控制投影机的为开机状态，进一步的，可以判断第一信号接收管接收到的预设信号对应的距离值是否大于预设阈值，若是，则确定为开机状态，此时避免了在小空间内的误触现象的发生；当第二信号接收管接收到预设信号，且第一信号接收管未接收到预设信号，则控制投影机的为关机状态。
第二种，信号发射管与第一信号接收管分别设置在光机镜头200的两端的预设范围内，其中，信号发射管设置在光机镜头200近投影机舱体100的一端，第二信号接收管设置在投影机舱体100的远离光机镜头200的一端。例如，400-1是信号发射管，400-2为第一信号接收管，400-3为第二信号接收管，此时，当驱动主板500检测到第一信号接收管接收到预设信号，且第二信号接收管未接收到预设信号，则控制投影机的为开机状态，进一步的，可以判断第一信号接收管接收到的预设信号对应的距离值是否大于预设阈值，若是，则确定为开机状态，此时避免了在小空间内的误触现象的发生；当第二信号接收管接收到预设信号，且第一信号接收管未接收到预设信号，则控制投影机的为关机状态。
通过结构设计，保证发射管始终不被遮挡，通过驱动主板500控制TOF器件工作并检测两个第一信号接收管和第二信号接收管的数据值，即可控制投影的开关机。当关机状态：当滑盖300遮挡到光机镜头200时，视投影机为关机状态，由于第一信号接收管被滑盖300遮挡，所以只有第二信号接收管接收到来自信号发射管的信号信息；第一信号接收管无数据，第二信号接收管可正常获取投影仪据投影幕布的距离，则控制为关机状态。可以理解的是，存在当滑盖300未遮挡到光机镜头，且没有检测到位时，此时第一信号接收管和第二信号接收管会同时有数据接收。第一信号接收管和第二信号接收管可正常获取投影机据投影幕布的距离。可以理解的是，若距离大于预设距离，则不进行任何操作或者开机状态，若距离小于预设距离，则确定为在小空间内误打开的情况，则执行关机状态。当滑盖300到位时，此时只有第一信号接收管收到测距数据；第一信号接收管可正常获取投影机据投影幕布的距离，第二信号接收管无数据，则控制为开机状态。
在一种可实现的实施方式中，第一信号接收管与第二信号接收管分别设置在光机镜头200的两侧的预设范围内，信号发射管设置在投影机舱体100的远离光机镜头200的一端；对应的，驱动主板，用于当信号发射管发射预设信号时，若检测到第一信号接收管或第二信号接收管没有接收到预设信号，则控制投影机为关机状态；若检测到第一信号接收管和第二信号接收管均接收到预设信号，且滑盖并未遮挡信号发射管，则控制投影机为开机状态。
例如，400-3是信号发射管，400-1为第一信号接收管，400-2为第二信号接收管，此时，若检测到第一信号接收管或第二信号接收管没有接收到预设信号，则控制投影机为关机状态；若检测到第一信号接收管和第二信号接收管均接收到预设信号，且滑盖并未遮挡信号发射管，则控制投影机为开机状态。具体的，当第一信号接收管是信号接收管A时，第二信号接收管是信号接收管B时，信号接收管B被遮挡，信号接收管B没有接收到预设信号，此时控制投影机为关机状态；当信号接收管A与信号接收管B均被遮挡，此时信号接收管A没有接收到预设信号，可以理解的是，当信号接收管A没有接收到预设信号则信号接收管B肯定没有接收到预设信号，因此，信号接收管A没有接收到预设信号，此时控制投影机为关机状态。当第一信号接收管是信号接收管B时，第二信号接收管是信号接收管A时，信号接收管A被遮挡，信号接收管A没有接收到预设信号，此时控制投影机为关机状态；当信号接收管B与信号接收管A均被遮挡，此时信号接收管B没有接收到预设信号，可以理解的是，当信号接收管B没有接收到预设信号则信号接收管A肯定没有接收到预设信号，因此，信号接收管B没有接收到预设信号，此时控制投影机为关机状态。
可见，通过利用TOF原理测距方法，检测第一信号接收管和第二信号接收管的预设信号和信号对应的数据的状态、值大小作为参考控制投影的开关。当然，还可以同时可配合遥控器开机，在保证开光机功能正常的同时也避免了异常开机的情况，如包内误触发开机。主要流程如下：通过驱动主板控制TOF持续进行距离数据的测量，判断测试投影机处于何种状态，并进行相应的操作。其中有遮挡物时主要防止在包内或狭小空间中开机，此情况下，R1依然有距离数据，但是此距离很近，可以通过区分数据的大小判断出投影此时再包内，从而不开启光机。
本实施例提供另一种投影机，本实施例提供另一种投影机，具体也可以参考图2，目标传感器400为测距传感器，包括三个组件，其中，任意两个组件400-1、400-2分别设置在光机镜头200的两端的预设范围内，最后一个组件400-3设置在投影机舱体100的远离光机镜头200的一端，400-1为信号接收管，400-2为第一信号发射管、400-3为第二信号发射管；驱动主板500，用于当第 一信号发射管、第二信号发射管发射预设信号时，根据检测到的预设信号控制工作状态。其中预设信号包括信号发射管的标识信息，当检测到第一信号发射管的信息且未检测到第二信号发射管的预设信号，则控制为打开状态，当检测到第二信号发射管的预设信号且未检测到第一信号发射管的预设信号，则控制为关闭状态。进一步的，当检测到第一信号发射管的预设信号且未检测到第二信号发射管的预设信号，且第一信号发射管的预设信号对应的距离大于预设距离，则控制为打开状态。
