本申请主张在2018年10月25日在中国提交的中国专利申请号No.201811248015.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开的一些实施例涉及通信技术领域，尤其涉及一种距离传感装置、电子设备及距离检测方法。
背景技术
随着电子设备的快速发展，用户对电子设备的外观要求也越来越高。目前，大多数电子设备具有距离传感器(即红外光敏)，在电子设备上设置距离感应传感器时，需要在盖板的油墨层进行开孔处理，并在油墨层上开孔处理的位置涂红外线(Infrared Radiation，IR)油墨，使红外光射出之后能有足够的反射能量被检测。这种距离感应传感器在安装于电子设备时，需要对电子设备的盖板进行加工处理，不利于生产操作，并且由于IR油墨为黑色，也即开孔呈黑色，导致具有白色或者其他颜色盖板的电子设备中，开孔位置处的颜色与盖板上的其他区域的颜色具有明显反差。
发明内容
本公开提供了一种距离传感装置、电子设备及距离检测方法，以解决相关技术中盖板上对应距离感应传感器开孔位置处的颜色与盖板上的其他区域的颜色具有明显反差的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开的一些实施例提供了一种距离传感装置，包括：
发射管，用于发射红外光线；
第一接收管，用于接收第一发射光线照射到目标体后反射的第一反射光线，其中，所述第一发射光线为所述发射管以第一功率发射的红外光线；
第二接收管，用于接收第二发射光线照射到所述目标体后反射的第二反射光线，其中，所述第二发射光线为所述发射管以第二功率发射的红外光线；
其中，所述第一接收管距离所述发射管的第一距离与所述第二接收管距离所述发射管的第二距离不同。
第二方面，本公开的一些实施例还提供了一种电子设备，包括如上所述的距离传感装置。
第三方面，本公开的一些实施例还提供了一种距离检测方法，应用于如上所述的电子设备，其中所述第一接收管距离所述发射管的第一距离大于所述第二接收管距离所述发射管的第二距离，所述方法包括：
控制所述发射管以第一功率发射第一发射光线，并通过所述第一接收管接收所述第一发射光线照射到目标体后反射的第一反射光线；
根据接收所述第一反射光线的第一时长，确定所述电子设备与所述目标体之间的第一距离。
在本公开的一些实施例中，通过设置与发射管之间的距离不同的第一接收管和第二接收管，分别进行近通道和远通道检测。这样，在感应目标体的距离时，可以不需要借助IR油墨层，即可保证发射光线的能量。特别是在远通道检测时，可以不需要借助IR油墨层，即可保证有足够的能量感应到较远距离的目标体，并且可以在调大功率导致噪声增加时减少噪声带来的干扰。

具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，本公开的一些实施例提供了一种距离传感装置，包括：发射管1、第一接收管2以及第二接收管3，其中，所述第一接收管2距离所述发射管1的第一距离与所述第二接收管3距离所述发射管1的第二距离之间不同。
其中，发射管1用于发射红外光线。
第一接收管2用于接收第一发射光线照射到目标体后反射的第一反射光线，其中，所述第一发射光线为所述发射管1以第一功率发射的红外光线。
第二接收管3用于接收第二发射光线照射到所述目标体后反射的第二反射光线，其中，所述第二发射光线为所述发射管1以第二功率发射的红外光线。
具体的，在所述第一距离大于所述第二距离的情况下，所述第一功率大于所述第二功率；在所述第一距离小于所述第二距离的情况下，所述第一功率小于所述第二功率。
作为一种实现方式，第一接收管2距离发射管1的第一距离大于第二接收管3距离发射管1的第二距离，即第一接收管2作为远通道，第二接收管3作为近通道。在进行近通道检测时，发射管1需要调节较小的第二功率发射第二发射光线，以避免近通道达到数据饱和；在进行远通道检测时，为保证第一发射光线有足够的能量照射到目标体，并能够通过第一接收管2接收到第一反射光线，则发射管1需要调节较大的第一功率发射第一发射光线。这样，由于第一接收管2距离发射管1的第一距离大于第二接收管3距离发射管1的第二距离，可以在调大功率导致噪声增加时减少噪声带来的干扰。
作为另一种实现方式，第一接收管2距离发射管1的第一距离小于第二接收管3距离发射管1的第二距离，即第一接收管2作为近通道，第二接收管3作为远通道。在进行近通道检测时，发射管1需要调节较小的第一功率发射第一发射光线，以避免近通道达到数据饱和；在进行远通道检测时，为保证第二发射光线有足够的能量照射到目标体，并能够通过第二接收管3接收到第二反射光线，则发射管1需要调节较大的第二功率发射第二发射光线。这样，由于第二接收管3距离发射管1的第二距离大于第一接收管2距离发射管1的第一距离，可以在调大功率导致噪声增加时减少噪声带来的干扰。
该实施例中，通过设置与发射管1之间的距离不同的第一接收管2和第二接收管3，分别进行近通道和远通道检测。这样，在感应目标体的距离时，可以不需要借助IR油墨层，即可保证发射光线的能量。特别是在远通道检测时，可以不需要借助IR油墨层，即可保证有足够的能量感应到较远距离的目标体，并且可以在调大功率导致噪声增加时减少噪声带来的干扰。
其中，所述发射管1、所述第一接收管2和所述第二接收管3可以位于一直线上，也可以位于非直线上，即所述发射管1、所述第一接收管2和所述第二接收管3的几何中心两两连接可以构成三角形，如图2所示。
可选地，为了便于排线布置，以及节省安装材料，可以将所述发射管1、所述第一接收管2和所述第二接收管3设置在同一直线上。
具体的，如图1，发射管1可以位于所述第一接收管2和所述第二接收管3之间，也即第一接收管2和所述第二接收管3位于一直线上时，第一接收管2位于发射管1的第一侧，第二接收管3位于发射管1的第二侧，其中第一侧和第二侧相对设置。
如图3，所述第一接收管2和所述第二接收管3还可以是相邻设置，所述发射管1与所述第一接收管2和所述第二接收管3中的一个相邻设置。具体的，当第一接收管2作为近通道，第二接收管3作为远通道时，发射管1与所述第一接收管2相邻设置；当第二接收管3作为近通道，第一接收管2作为远通道时，发射管1与第二接收管3相邻设置。这样，无论发射管1是与第一接收管2相邻设置，还是与第二接收管3相邻设置，都可以保证第一接收管2和第二接收管3中的一个作为近通道，另一个作为远通道，可以避 免由于设置第一接收管距离发射管的第一距离与第二接收管距离发射管的第二距离不同，可能导致空间受限的问题，从而有利于空间布局。
其中，所述距离传感装置还包括：电路板4；所述发射管1、所述第一接收管2和所述第二接收管3分别与所述电路板4连接。
具体的，所述发射管1、所述第一接收管2和所述第二接收管3可以分别通过焊锡的方式与所述电路板4连接，以保证连接的稳定性；或者，所述发射管1、所述第一接收管2和所述第二接收管3还可以分别通过连接器与所述电路板4连接，以便于拆卸。
如图4，本公开的一些实施例还提供了一种电子设备，包括如上所述的距离传感装置。其中，电子设备可以是手机、平板电脑、智能手表等具有距离传感装置的设备。
具体的，该距离传感装置包括：发射管1、第一接收2以及第二接收管3，其中，所述第一接收管2距离所述发射管1的第一距离与所述第二接收管3距离所述发射管1的第二距离不同。
其中，发射管1用于发射红外光线。
第一接收管2用于接收第一发射光线照射到目标体后反射的第一反射光线，其中所述第一发射光线为所述发射管1以第一功率发射的红外光线。
第二接收管3用于接收第二发射光线照射到所述目标体后反射的第二反射光线，其中所述第二发射光线为所述发射管1以第二功率发射的红外光线。
具体的，在所述第一距离大于所述第二距离的情况下，所述第一功率大于所述第二功率；在所述第一距离小于所述第二距离的情况下，所述第一功率小于所述第二功率。
作为一种实现方式，第一接收管2距离发射管1的第一距离大于第二接收管3距离发射管1的第二距离，即第一接收管2作为远通道，第二接收管3作为近通道。在进行近通道检测时，发射管1需要调节较小的第二功率发射第二发射光线，以避免近通道达到数据饱和；在进行远通道检测时，为保证第一发射光线有足够的能量照射到目标体，并能够通过第一接收管2接收到第一反射光线，则发射管1需要调节较大的第一功率发射第一发射光线。这样，由于第一接收管2距离发射管1的第一距离大于第二接收管3距离发 射管1的第二距离，可以在调大功率导致噪声增加时减少噪声带来的干扰。
作为另一种实现方式，第一接收管2距离发射管1的第一距离小于第二接收管3距离发射管1的第二距离，即第一接收管2作为近通道，第二接收管3作为远通道。在进行近通道检测时，发射管1需要调节较小的第一功率发射第一发射光线，以避免近通道达到数据饱和；在进行远通道检测时，为保证第二发射光线有足够的能量照射到目标体，并能够通过第二接收管3接收到第二反射光线，则发射管1需要调节较大的第二功率发射第二发射光线。这样，由于第二接收管3距离发射管1的第二距离大于第一接收管2距离发射管1的第一距离，可以在调大功率导致噪声增加时减少噪声带来的干扰。
该实施例中的电子设备，通过在距离传感装置中设置与发射管1之间的距离不同的第一接收管2和第二接收管3，分别进行近通道和远通道检测。采用这种距离传感装置的电子设备在感应目标体的距离时，可以不需要设置IR油墨层，即可保证发射光线的能量。特别是在远通道检测时，可以不需要借助IR油墨层，即可保证有足够的能量感应到较远距离的目标体，并且可以在调大功率导致噪声增加时减少噪声带来的干扰。
其中，所述的距离传感装置还包括：电路板4；所述发射管1、所述第一接收管2和所述第二接收管3分别与所述电路板4连接。
具体的，所述发射管1、所述第一接收管2和所述第二接收管3可以分别通过焊锡的方式与所述电路板4连接，以保证连接的稳定性；或者，所述发射管1、所述第一接收管2和所述第二接收管3还可以分别通过连接器与所述电路板4连接，以便于拆卸。

可选地，所述发射管1、所述第一接收管2和所述第二接收管3与所述盖板5之间的距离为0～1mm。
该实施例中的电子设备，通过在距离传感装置中设置与发射管1之间的距离不同的第一接收管2和第二接收管3，分别进行近通道和远通道检测。 采用这种距离传感装置的电子设备在感应目标体的距离时，可以不需要设置IR油墨层，即可保证发射光线的能量，从而避免在盖板5上进行开孔处理，减小了盖板5上的开孔数量，保证盖板5的外观完整性，还可以避免白色或者其他颜色的盖板5上涂设IR油墨层导致的外观违和，并且减少了盖板5的制作工艺流程，降低了盖板5的工艺制作难度。
其中，如图5，所述盖板5包括显示区51以及包围所述显示区域51设置的非显示区域52。
所述发射管1、所述第一接收管2和所述第二接收管3在所述盖板5上的投影处于所述非显示区域52内，以避免电子设备内部空间的占用，从而有利于电子设备内部的空间管理，有利于整机的轻薄化。
具体的，所述发射管1、所述第一接收管2和所述第二接收管3可以在非显示区域53下方的任意位置进行设置。为了便于排线布置，以及节省安装材料，可以将所述发射管1、所述第一接收管2和所述第二接收管3可以设置在一直线上；为了避免远通道的干扰，也可以将所述发射管1、所述第一接收管2和所述第二接收管3设置在非直线上，即所述发射管1、所述第一接收管2和所述第二接收管3集合中心两两连接可以构成三角形。
具体的，如图4，发射管1可以位于所述第一接收管2和所述第二接收管3之间，也即第一接收管2和所述第二接收管3位于一直线上时，第一接收管2位于发射管1的第一侧，第二接收管3位于发射管1的第二侧，其中第一侧和第二侧相对设置。
