Description

一种3D显示头盔控制装置 技术领域
本发明涉及一种穿戴式设备，特别涉及一种穿戴式显示头盔。
背景技术
头盔显示屏(Helmet-MountedDisplays,HMDs)是利用光学系统将微显示屏发出的图像信息投影在人眼前成放大的虚像，对于视透型头盔显示屏，佩戴者除了显示屏上的画面，还可以同时看见真实世界的情况，有较好的环境感知能力。但是现有的头盔显示屏的控制系统一般只包括信号接收传输显示的功能，而不同时穿戴者对于显示屏的位置有着不同的需求，长时间的观看不适当位置的显示屏容易导致穿戴者的视觉疲劳，从而影响穿戴者的视力，而现有的控制系统无法实现这样的功能。
发明内容
本发明的目的是提供一种3D显示头盔控制装置，使得穿戴者使用时更加舒适，保护穿戴者的视力。
本发明的目的是这样实现的：一种3D显示头盔控制装置，包括主控电路，主控电路上连接有蓝牙接收电路、视焦距调节装置、显示驱动电路和声音驱动电路，显示驱动电路上连接有显示屏，声音驱动电路连接有耳机，所述视焦距调节装置包括调节按钮、电机驱动电路以及伺服电机，调节按钮主控电路相连，主控电路与电机驱动电路相连，电机驱动电路与控制显示屏位移的伺服电机相连。
本发明工作时，穿戴者可通过调节按钮配合主控电路、电机驱动电路以及伺服电机调节显示屏的位置，以适应穿戴者的需求，与现有技术相比，本发明的有益效果在于，本发明可通过按钮调节显示屏的位置，使得穿戴者在使用显示头盔是更加舒适，保护了使用者的视力。本发明可用于3D显示头盔中。
作为本发明的进一步改进在于，所述视焦距调节装置为手动机械调节装置，使用者根据自身视觉清晰度调整视焦距。所述视焦距调节装置还可以为自动调节装置，该自动调节装置通过探测眼底聚焦点，使得图像显示在眼底的聚焦点上。该技术方案保证了使用者可以轻松观看图像，避免视觉疲劳。
附图说明
图1为本发明的控制原理框图。
具体实施方式
如图1所示的一种3D显示头盔控制装置，包括主控电路，主控电路上连接有蓝牙接收电路、视焦距调节装置、显示驱动电路和声音驱动电路，显示驱动电路上连接有显示屏，声音驱动电路连接有耳机，所述视焦距调节装置包括调节按钮、电机驱动电路以及伺服电机，调节按钮主控电路相连，主控电路与电机驱动电路相连，电机驱动电路与控制显示屏位移的伺服电机相连。视焦距调节装置可以为手动机械调节装置，使用者根据自身视觉清晰度调整视焦距。所述视焦距调节装置还可以为自动调节装置，该自动调节装置通过探测眼底聚焦点，使得图像显示在眼底的聚焦点上。保证了使用者可以轻松观看图像，避免视觉疲劳。
本发明工作时，视听信号通过主机发送给蓝牙接收电路，再通过主控电路对该视听信号进行处理发送给显示驱动电路和声音驱动电路，将视频信号发送给显示屏显示，将声音信号发送给耳机播放，使用时，穿戴者可通过调节按钮，配合主控电路、电机驱动电路以及伺服电机调节显示屏的位置，使得穿戴者使用时更加舒适，从而保护了穿戴者的视力。
本发明并不局限于上述实施例，在本发明公开的技术方案的基础上，本领域的技术人员根据所公开的技术内容，不需要创造性的劳动就可以对其中的一些技术特征作出一些替换和变形，这些替换和变形均在本发明的保护范围内。
