同样，在显示屏101绕Z轴方向旋转的角度调节中，显示屏101将需调节的角度信息传递给控制器，控制器根据该角度信息控制第三动力机构131工作，继而带动第三齿轮1323和/或第二丝杠1322转动，在导向杆134作用下，使得第二丝杠螺母1321实现直线平动；进而带动第二推杆133移动，推动显示屏101绕Z轴旋转。可选地，在该系统调节显示屏101绕Z轴旋转的同时，控制器将获取的显示屏当前状态与旋转角度与输入角度信息进行对比，进而控制电机停止工作，从而可以实现系统的闭环控制。显示屏绕Z轴旋转的角度调节范围可根据需求设定，例如，在一种可能的设定中，该显示屏绕Z轴旋转的角度调节范围可以为[-30°，30°]。
(3)显示屏绕X轴方向旋转的角度调节
在显示屏绕X轴方向旋转的角度调节中，由于Y轴和Z轴均连接在显示屏101上，在显示屏101在旋转的过程中，Y轴和Z轴的角度也会发生变动，因此Y轴和Z轴对应也需要同步转动。显示屏将需调节的角度信息传递给控制器，控制器根据该角度信息控制第一动力机构111工作，带动第一传动机构112；继而带动第一旋转轴113旋转。于此同时，控制器也控制第二动力机构121以及第三动力机构131工作，并带动各自转动机构的部件进行工作，进而实现显示屏101在X轴旋转的过程中，Y轴和Z轴角度的恒定。
其次，若控制器的角度调节信息同时包括绕Y或Z轴旋转的角度信息，则显示屏101将角度信号传递给控制器，控制器控制第一动力机构111、第二动力机构121以及第三动力机构131同时工作，并带动各自转动机构的部件进行工作，进而在保证在显示屏101在绕X轴旋转的同时，实现显示屏绕Y/Z两轴旋转的角度调节。显示屏绕X轴旋转的角度调节范围可根据需求设定，例如，在一种可能的设定中，该显示屏绕X轴旋转的角度调节范围可以为[0°，180°]。
除自动调节模式外，该系统中还可以设置有手动调节模式。在手动调节模式下，通过压力传感器感测手推动显示屏时产生的压力，该压力传感器将对应的压力信息传输到控制器；控制器根据该压力信息控制对应的动力机构工作。可选地，还可以在控制器中设置压力阈值，当控制器检测到接收的压力信息所表示的压力达到该阈值时，控制对应的电机工作，进而实现显示屏对应角度的调节。当显示屏调节到位时，压力传感器对应的压力信号也会减弱，如果各个轴的压力低于控制器中设定的阈值，则控制器不做任何反馈或输出；在完成调节之后，保存当前状态并退出手动调节模式，同时，控制器将不对传感器信号做出反应，实现显示屏位置的锁定。
可选地，还可以在控制器中设置各动力机构的电流阈值，控制器通过对各个动力机构的电流进行检测，当电流超过设定的阈值时，控制电机停止工作，同时，控制器还可以控制电流超过阈值的动力机构反转一定的角度，进而实现防夹功能。
进一步地，该控制器还可以接收上层应用软件的控制信号，实现显示屏的应用软件控制，进而实现更加智能的角度调节。例如，导航情况下的自动竖屏，电影、游戏模式下的自动横屏，音乐模式下的震动等效果。
该控制器还可以和其他设备，例如摄像头、扬声器等配合，实现更加人性化的人机交互功能。例如，控制器可以通过扬声器采集声音信息确定声源位置，或者通过摄像头采集图像确定车内人员的位置信息，进而控制显示屏的旋转角度实时调节、或者控制显示屏点头、摇头等，实现更加智能的交流和互动。还可以通过驾驶员的账号信息绑定，可以实现更加智能化和便捷性的显示屏角度记忆功能。
图9所示为该显示屏角度调节系统的控制方法，该方法可以包括以下步骤，该方法可以由控制器执行。
S910，确定显示屏初始角度信息。
S920，接收上层控制信息。
应理解，该上层控制信息可以来自显示屏、控制器、压力传感器等，该上层控制信息可以包括上层路况信息，驾驶员调节信息，娱乐系统模拟信息以及摄像头信息等。
S930，确定显示屏调节模式。
该显示屏调节模式包括手动调节模式和自动调节模式。该显示屏调节模式可以根据上层输入信号确定，例如，通过压力传感器信号确定该显示屏调节模式为手动模式；通过摄像头信号确定该显示屏调节模式为自动模式(例如，自动横屏)，进行最佳娱乐互动角度调节。
S940，确定显示屏需调节的角度信息。
应理解，控制器可以通过显示屏当前角度信息和该控制信息确定显示屏需调节的角度信息，并根据该显示屏需调节的角度信息控制各转动机构转动，实现显示屏角度的调节。
S950，根据显示屏当前角度信息和显示屏需调节角度信息确定各动力机构停止工作，实现该显示屏调节系统的闭环控制。
