Description

Technical Field

[0001] The utility model relates to the technical field of optical imaging, in particular to a vehicle rear seat viewing device. Background Art

[0002] New energy vehicles and smart driving are becoming more and more popular among the public. The reason is that cars are no longer simple means of transportation, but smart devices integrated with various functions. While driving, people in the back seat of the car will feel bored after sitting in the car for a long time. A common pastime is to look at the mobile phone. However, this kind of long-term viewing of the mobile phone is not only easy to cause visual fatigue, but also sitting for a long time holding the mobile phone will be tiring. Patent application number CN201410103983.1 discloses a head-mounted stereoscopic viewing device, including an eye mask, a frame, a visual magnification optical system and a plane reflector, wherein: a accommodating groove is provided above or below the frame for placing a mobile terminal serving as a video playback source; the eye mask is connected to one end of the frame, and the visual magnification optical system is installed at the connection position between the frame and the eye mask; a partition piece is provided in the center of the frame for completely isolating the images seen by the two eyes; the plane reflector is installed in the frame at an angle of 30 to 60 degrees to the display screen of the placed mobile terminal, and the plane reflector deflects the light information emitted by the display screen of the mobile terminal and enters the human eye through the visual magnification optical system; when watching a video using the head-mounted stereoscopic viewing device of the present invention, when the mobile terminal screen plays the video source, the video needs to be converted into two left and right images, and the two images are separated by the partition piece in the center of the frame to avoid interference of the left image on the right eye and interference of the right image on the left eye. When the left and right images are completely identical, it is a normal 2D video. When there is a certain position difference between the left and right images, it is a 3D stereoscopic image. Although this stereoscopic viewing device can achieve a 3D effect, the headband viewing device needs to be worn on the head for a long time. After watching movies for a long time, it can cause dizziness and vertigo. Wearing it in a car can aggravate this dizziness and vertigo, which can easily aggravate the passengers' motion sickness and poor the riding experience. Moreover, it can only be worn one-on-one, and when there are multiple people in the back seat, they cannot watch at the same time.
