technical field

The utility model relates to the technical field of milk heating devices, in particular to a head-mounted virtual reality device.

Background technique

A head-mounted virtual reality device is a device that can be worn on the head for display (Head Mounted Device, HMD for short). Virtual reality is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, so that users can feel as if they are on the scene. It is a combination of various technologies to provide users with a full range of virtual reality. . As a virtual reality display device, the head-mounted virtual reality device has the characteristics of small size and strong sealing, and has a wide range of applications in projects such as military training, virtual driving and virtual cities.

The display principle of the head-mounted virtual reality device is that the images of the left and right eyes are displayed on the screen of the left and right eyes respectively. After the human eyes obtain this information with differences, they will generate a three-dimensional effect in the mind, and guide the user to have a feeling of being in a virtual environment. . But at present, most of the head-mounted display devices in the prior art have single functions, cannot fully realize virtual reality, and have the disadvantages of weak presence and perception; and the wearing comfort is not satisfactory, and the stability is not enough. The fit of the application is not good, resulting in poor user experience and limited application range.

The second convex lens is on the second optical axis, and the video image in the left and right split screen format is displayed in the first display screen and the second display screen, and the pictures displayed in the left and right split screens are respectively passed through the first convex lens and the second convex lens. It is projected into the left and right eyes, thereby forming a three-dimensional three-dimensional image in front of the human eyes; detachable earphones are connected to both sides of the elastic connecting part, and a head-mounted strip is arranged above the elastic part, and the two ends of the head-wearing strip are respectively connected to the elastic connecting part. connected, the inner side of the head strap is provided with a head pad.

As a preferred solution, the first display screen and the second display screen have the same size, and both are TFT-LCD liquid crystal display screens.

As a preferred solution, the shade is made of foldable inert sponge or foldable soft glue or foldable fleece.

As a preferred solution, the face fitting part is made of shape memory material or hard plastic material.

The beneficial effects of the utility model: the first display screen and the second display screen display images for the wearer; the upper and lower edges of the face fitting part make the head-mounted virtual reality device fit well and have a strong sense of comfort. The upper edge of the fitting part refers to the upper edge after fitting the face, that is, the side close to the forehead; the same lower edge of the fitting part refers to the lower edge after fitting the face, that is, Near the nose side; the shading piece protects the wearer from external influences, and can better feel the visual enjoyment brought by the head-mounted virtual reality device. The earphones give the wearer an auditory virtual reality. Better fixed on the back of the wearer's head, the head-mounted strip can prevent the head-mounted virtual reality device from slipping off and improve the stability of the head-mounted virtual reality device.
