Description

AR glasses

Technical Field

The application relates to the technical field of AR (augmented reality) glasses structural design, in particular to AR glasses.

Background

With the development of display technology, AR glasses based on the Birdbath optical scheme are designed and developed. The AR glasses of the Birdband scheme have the advantages of low manufacturing cost, light weight, easiness in industrialization and the like, and are an important research direction for the masses at present. However, the AR glasses of the Birdbath scheme still have some problems, and the light transmittance of the lenses is too low, only 10% -20%, and the outside cannot be seen clearly. Based on this, AR glasses are currently used only in specific scenes such as games, educational presentations, museum navigation, etc. in specific areas, and users do not carry about as with ordinary glasses. The problem of low light transmittance of the prior AR glasses severely limits the use scene of the AR glasses.

The existing AR glasses support functions of voice control, music playing, game interaction and the like besides the function of displaying pictures. Most of the prior AR glasses are provided with Bluetooth modules, and the AR glasses can be connected with a mobile phone of a user through the built-in Bluetooth modules, so that mobile phone pictures can be displayed in the AR glasses, the display content of the AR glasses is expanded, and functions of watching movies, receiving calls and the like are realized. However, because the AR glasses of the Birdbath scheme have the limitation of lower light transmittance, when the user needs to observe the external environment, the AR glasses need to be taken off, so that the AR glasses of the Birdbath scheme cannot be worn for a long time in daily life, and further, other functions of the AR glasses cannot be reasonably utilized.

At present, intelligent glasses with various interaction sensors such as an accelerometer and a gyro sensor are also arranged on the market. When this intelligent glasses is connected with the cell-phone bluetooth, can become intelligent assistant, carry out schedule suggestion, weather report etc. to the user, can also remind user's bad gesture in schedule life. The intelligent glasses widen the use scene of the mobile phone, so that the mobile phone is safer to use in certain specific scenes (such as riding a escalator, crossing a road, and the like). In addition, many intelligent glasses on the market all support the lens change of different myopia degrees at present for intelligent glasses more press close to user's daily life. Users prefer to carry the intelligent glasses with them instead of the AR glasses, and the appearance of the intelligent glasses impacts the market of the AR glasses, which affects the use rate of the AR glasses.

Although the smart glasses can realize most of functions of the AR glasses, the functions of the AR glasses to display mobile phone pictures cannot be realized. Therefore, there is a need to overcome the problem of low light transmittance of the above AR glasses, and design and develop an AR glasses that can be worn in daily life.

The main control circuit controls the operation of the display unit 10, and the sub-control circuit controls the operation of the other functional units 23, so that even when the display unit 10 is detached from the auxiliary eyeglasses 20, the AR eyeglasses 1 can be used for functions other than the display screen.

Specifically, referring to fig. 1 to 5, the AR glasses 1 may include a display light machine 10, an auxiliary glasses 20, and a docking connector 30, the display light machine 10 may include a light machine housing 13, a light machine main body 11 mounted on the light machine housing 13, and a main circuit board 12 mounted on the light machine housing 13, wherein the main circuit board 12 is electrically connected to the light machine main body 11. The optical machine body 11 is used for emitting a display image. The auxiliary glasses 20 comprise a glasses main body 21, a secondary circuit board 22 arranged on the glasses main body 21 and a functional component 23 arranged in the glasses main body 21, wherein the functional component 23 can realize functions of playing audio or inputting audio, or is connected with a mobile phone to realize functions of calendar reminding, voice navigation, and the like. The sub-circuit board 22 is electrically connected to the functional module 23. The docking connector 30 includes a connector 31 disposed on the light engine housing 13 and a docking connector 32 disposed on the glasses main body 21, the connector 31 is electrically connected to the main circuit board 12, the docking connector 32 is electrically connected to the secondary circuit board 22, and the connector 31 is electrically plugged into the docking connector 32 to detachably mount the display light engine 10 on the auxiliary glasses 20. In other words, when the user needs to watch the display image of the AR glasses 1, the connector 31 may be plugged into the connector 32 to mount the display light machine 10 on the auxiliary glasses 20, so as to realize the function of the AR glasses 1. When the user needs to observe the external environment, the connector 31 can be removed from the docking device 32 to detach the display light machine 10 from the auxiliary glasses 20, and the auxiliary glasses 20 can realize other functions such as calling, playing music, and voice navigation besides the display screen. In this way, the auxiliary glasses 20 can be used as the AR glasses 1 when the display light machine 10 is attached, and even if the display light machine 10 is detached from the auxiliary glasses 20, the auxiliary glasses 20 can be used as the smart glasses.

More specifically, as shown in fig. 1 and 3, in one embodiment, when the display light engine 10 is mounted on the auxiliary glasses 20, the main circuit board 12, the light engine main body 11, the auxiliary circuit board 22 and the functional components 23 form a main control circuit, and a driver on the main circuit board 12 can drive the display light engine 10 to emit a display image and drive the functional components 23 to operate. When the display light engine 10 is detached from the auxiliary spectacles 20, the secondary circuit board 22 and the functional components 23 form a secondary control circuit. The driver on the secondary circuit board 22 is capable of driving the functional component 23 to operate. In other words, the main circuit board 12 and the secondary circuit board 22 are both provided with CPUs, and in the main control circuit, the secondary circuit board 22 is controlled by the main circuit board 12 to drive the functional component 23 to work, so that the functional component 23 can better cooperate with the optical engine main body 11 to work.
