Description

Holding formula VR glasses

Technical Field

The invention relates to VR glasses, in particular to accommodating VR glasses.

Background

VR glasses, i.e. VR head-mounted display, are known as virtual reality head-mounted display devices, and generally can project stereoscopic images of left and right formats to the left and right eyes of a user, respectively, so that the eyes can generate a 3D stereoscopic impression in the mind after acquiring information with differences, thereby realizing VR (virtual reality) functions. In recent years, a receiving type VR glasses capable of receiving a mobile phone is proposed, and when the mobile phone is installed in the receiving type VR glasses, a screen of the receiving type VR glasses can be used for playing a stereoscopic image in a left-right format, so that electronic equipment such as a display screen is not required to be arranged on the VR glasses, the VR glasses are very low in price, and the receiving type VR glasses have an important significance in popularization of virtual reality.

However, because the VR glasses shell is necessarily closed, when the mobile phone is installed inside the VR glasses, the user cannot directly control the mobile phone, which is very inconvenient in use.

At present, in order to solve the above problems, some people also set a wireless controller, such as a bluetooth controller, on the VR glasses to connect with the fixed mobile phone through bluetooth, however, such a bluetooth controller generally needs to connect with a battery, which may increase the weight of the VR glasses and reduce the comfort of the VR glasses during use.

The lens cavity of the VR glasses is generally provided with left and right magnifying lenses (or lens sets), which can be fixed in front of the eyes of the user by a certain fixing mechanism (such as a fixing belt), so that the left and right eyes of the user can watch the contents on the other side of the lenses through the left and right lenses respectively. The accommodating part can be a fixing cavity, a fixing box or a fixer of the mobile phone. The external keys may be mechanical keys (e.g., keys including snap buttons) or inductive keys (e.g., capacitive inductive keys), and may be disposed on the housing of the VR glasses or on a control lever connected to the VR glasses. The near-field induction coil can be a spiral coil formed by a conductor, such as a metal wire or a metal layer made of conductive ink, nano silver paste and the like through printing and other processes, and the coil is connected with the key circuit at least from two end points serving as an electric energy output end and/or a signal feed-in end. The key circuit may be a chip or a circuit with a near field communication function, and specifically, it may include a power filter module, a key trigger module, a signal transmission module, a storage module, and a microprocessor, where the power filter module may process an input voltage of the near field induction coil and provide a stable voltage to other modules, for example: the key trigger module can generate a corresponding key signal according to the switch of an external key and send the key signal to the microprocessor for corresponding operation and feedback, the signal transmitting module can further modulate the key signal and feed the key signal back to the induction coil, and the storage module can be used as a storage medium for storing communication protocols, access information and read-write data.

From this, when the cell-phone has the near field communication function, perhaps when pasting near field communication function's the back of the body, install the cell-phone in this kind of holding formula VR glasses, through the software setting on the cell-phone, can realize the communication of cell-phone and VR glasses, wherein, VR glasses accessible near field induction coil obtains the electric energy from the cell-phone, and it need not carry the battery itself, has reduced the weight of VR glasses. In addition, the mobile phone installed in the accommodating VR glasses can preferably recognize data information (such as anti-counterfeiting or advertisement information in an NFC tag mode) on the near field induction coil, when an external key of the VR glasses is touched, the VR glasses can send a key signal to the mobile phone through the key circuit and the near field induction coil, and the mobile phone executes a corresponding command to implement the operation and display functions.

In a preferred aspect of the present invention, the external keys are disposed on a housing of the VR glasses. Will the outside button sets up on the casing of VR glasses, supports outside button according to the casing of VR glasses, has reduced the bearing structure of outside button, can further reduce the weight of VR glasses from this.

In a preferred embodiment of the present invention, the accommodating portion is a mobile phone fixing cavity, and includes a rear cover capable of covering the mobile phone, and the near field induction coil is disposed on the rear cover, so that the induction coil is more conveniently aligned to the back of the mobile phone, and the mobile phone is more conveniently used.

In a preferable scheme of the invention, the induction heating device further comprises a sticker, wherein the induction coil is arranged on the sticker, and the sticker is adhered to the inner side of the rear cover. Set up induction coil on the sticker to adopt the mode of adhesion to set up it inboard at the back lid, from this, saved fixed induction coil's structure, further reduced the weight of VR glasses.

In a further preferred embodiment of the present invention, the external keys are disposed on a side surface of the mobile phone fixing cavity. Therefore, the distance between the external key and the induction coil and the distance between the key circuit and the induction coil can be shortened, and the weight of VR glasses can be further reduced.

Compared with the prior scheme, the invention has the advantages that:

through the control system that induction coil, keying circuit and outside button constitute, can control the cell-phone of installing in the VR glasses, wherein, the VR glasses passes through induction coil and obtains the electric energy from the cell-phone, saves the setting of battery, has further reduced the weight of VR glasses, has light in weight, can interactive advantage, and it is also more comfortable that it uses. In addition, the VR glasses can be designed to enable the mobile phone to identify and display anti-counterfeiting data information on the near-field induction coil.
