Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example 1

The utility model provides a VR glasses for preschool education, includes glasses cover 1, fixed bandeau 2, display screen 3, focusing device 4, is equipped with display screen 3 in the

glasses cover

1, and 3 sides of display screen are equipped with focusing device 4, the 3 backs of display screen are equipped with gyroscope 17 for the spatial position and the motion of perception VR glasses, and glasses cover 1 is equipped with fixed bandeau 2 on the horizontal direction, and glasses cover 1 is close to fixed bandeau 2 one side and is equipped with foam-rubber cushion 5, and glasses cover 1 side is equipped with earphone 6, and glasses cover 1 top centre position is equipped with first buckle 7, and the middle part of fixed bandeau 2 is equipped with second buckle 8, can connect flexible bandeau between first buckle 7 and the second buckle for fixed VR glasses, glasses cover 1 top still is equipped with timing device 12, is used for timing user's live time, and glasses cover 1 top edge is equipped with jack 11, video input jack 9, And an audio input jack 10 for supplying power, receiving video signals, and receiving audio signals, respectively.

The working principle is as follows: at first the teacher has set for the live time through the time-recorder, then the user fixes VR glasses overhead through fixed bandeau 2, fix vertically through flexible bandeau between first buckle 7 and second buckle 8 simultaneously, prevent that VR glasses from landing downwards, alleviate the oppression sense at bridge of the nose position, when the user takes VR glasses, the time-recorder begins the timing, after the timing time reaches the preset time, timing device 12 cuts off the power, make display screen 3 and earphone 6 stop work, the user is forced to take off glasses and has a rest.

Example 2

On the basis of the first embodiment, the sponge cushion 5 is arranged around the edge of the glasses cover 1, the sponge cushion 5 is in a round rectangle shape, so that the glasses cover is more comfortable to wear, the metal sheet 13 is arranged in the sponge cushion 5 and is opposite to the forehead of a user, the force sensitive resistor 14 is arranged on the inner side of the glasses cover 1 and corresponds to the metal sheet 13, one side, close to the force sensitive resistor 14, of the metal sheet 13 is connected with the metal rod 16, the spring 15 is arranged on the outer side of the metal rod 16, the metal rod 16 penetrates through the spring 15, when the user wears VR glasses, the forehead extrudes the metal sheet 13, so that the pressure between the metal rod 16 and the force sensitive resistor 14 is increased, the resistance value of the force sensitive resistor 14 is rapidly reduced, so that a circuit is switched on, the display screen 3, the earphone 6 and the timer 12 start to work, when the user takes off the VR glasses, the spring 15 enables the metal sheet to return to the initial position, the resistance value of the force sensitive resistor 14 is rapidly increased, so that the circuit is switched off, and stopping the VR glasses.
