Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.

The core of this application is to provide a novel AR glasses.

In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.

Fig. 1 is a structural diagram of a novel AR glasses provided in an embodiment of the present application. Fig. 2 is a hardware platform structure diagram of the novel AR glasses provided in the embodiment of the present application. Novel AR glasses include the glasses body, still include: a wireless communication system 1, a data conversion system 2 and a neck strap 3. Wherein, the glasses body includes picture frame 4, mirror leg 5, lens 6, AR ray apparatus 7, audio playback system 8, battery 9 and control system 10.

The wireless communication system 1 is used for establishing wireless connection with the terminal equipment so as to receive a signal to be played sent by the terminal equipment. It can be understood that the wireless communication system 1 may be a WIFI receiving system, and certainly, may also be bluetooth or the like in addition to WIFI, but when considering that the number of bytes of the signal to be played is large, the WIFI receiving system is usually adopted. The terminal device may be a computer or a mobile phone, and it should be noted that the terminal device and the wireless communication system 1 of the AR glasses are in the same communication network.

The data conversion system 2 is connected with the wireless communication system 1, and is mainly used for converting image signals and audio signals in signals to be played into signals which can be identified by the AR optical machine 7 and the audio playing system 8 in the glasses body respectively, and transmitting the converted signals to the AR optical machine 7 and the audio playing system 8 respectively. It should be noted that, it is not required that the signal to be played includes an image signal and an audio signal, but when the signal to be played includes both of them, the data conversion system 2 can convert the signals into signals that can be recognized by the AR optical machine 7 and the audio playback system 8. Because the AR glasses have the characteristic of long focal length, the visual experience of more than 100 inches can be experienced, and therefore the experience of the user is further improved.

Since the glasses are worn on the face of the user, the volume and weight of the glasses are important factors affecting the user experience. In fact, in the prior art, the AR glasses and the mobile phone are connected through the wire harness for signal transmission, so that the functions of the transmission cannot be integrated on the AR glasses, otherwise, the AR glasses are bulky and heavy. In this embodiment, through setting up a neck strap 3, set up partial hardware equipment in neck strap 3, this time, not only can realize the original function of AR glasses, can also reduce the volume and the weight of AR glasses. In this embodiment, the wireless communication system 1 and the data conversion system 2 are provided in the neck band 3. As a preferred embodiment, the neck strap 3 is made of a flexible material, which improves the comfort of the user. It will be appreciated that, since the neck strap 3 is to be worn around the neck of a user, the shape thereof is to be adapted to the shape of the neck, and an arc shape may be used. In addition, the neck strap 3 can be provided as an inflatable neck strap 3, and the neck strap 3 can be inflated to play a supporting role when the user travels or goes on a business trip. When not needed, the gas can be released, and the carrying is convenient.

The novel AR glasses provided by the embodiment comprise a glasses body, and further comprise a wireless communication system, a data conversion system and a neck strap. The wireless communication system is used for receiving a signal to be played sent by the terminal equipment, and the data conversion system is used for converting an image signal and an audio signal in the signal to be played into signals which can be identified by the AR optical machine and the audio playing system respectively and outputting the signals to the AR optical machine and the audio playing system to realize screen projection playing. The neck strap is used for carrying a wireless communication system and a data conversion system. Therefore, by adopting the technical scheme, on one hand, the signals to be played of the terminal equipment can be played on the AR glasses in a wireless transmission mode, so that the limitation of a wiring harness is eliminated, the watching experience which cannot be realized by a common screen is realized, on the other hand, the neck strap is adopted to bear a wireless communication system and a data conversion system, the space occupation of the glasses body is reduced, the size and the weight of the glasses are reduced, and the wearing experience of a user is improved.

In the above embodiment, the arrangement positions of the control system 10 and the battery 9 in the glasses body are not limited, and it can be understood that the energy storage of the battery 9 is an important parameter for measuring the standby time of the AR glasses. Under the technical limit, if the volume of the battery 9 is too small, it is difficult to achieve a large stored energy, so in view of this bottleneck problem, on the basis of the above-described embodiment, as a preferred embodiment, the control system 10 and the battery 9 in the eyeglass body are provided to the neckband 3. When the battery 9 and the control system 10 are provided in the napestrap 3, the volume of the battery 9 can be made appropriately large and the weight of the eyeglass body can be further reduced. It should be noted that, since the battery 9 needs to supply power to the AR light machine 7 and the like and the control system 10 needs to control the AR light machine 7 and the like, when the battery 9 and the control system 10 are disposed in the neck strap 3, they need to be connected to the corresponding devices through the connection line 11 (electric wire and signal wire), in which case, the neck strap 3, the connection line 11 and the glasses body can be fixedly connected.

In another embodiment, when the control system 10 and the battery 9 are small enough to meet the use requirement of the AR glasses, the battery 9 and the control system 10 can be embedded in the glasses frame 4, so that the neck strap 3 can be detachably connected with the glasses body. When the user need throw the screen, can insert the connector on the glasses body with connecting wire 11 on the nape-band 3, when the user need not throw the screen, can extract the connector on the glasses body with connecting wire 11 on the nape-band 3, concrete connected mode can adopt realization such as connector, and this embodiment is no longer repeated.
