Referring to fig. 1-4, an embodiment of a pair of virtual reality glasses 100 is provided, wherein the pair of virtual reality glasses 100 includes a frame 110, a light mechanism 120, a display lens 130, an electromagnet assembly 140, and a control main board 150, and the light mechanism 120 is movably disposed on the frame 110; the display lens 130 is arranged on the frame 110, and the display lens 130 is used for displaying the picture projected by the optical machine 120 so as to enable the eyeball to acquire the picture; the electromagnet assembly 140 includes a first magnetic member 141 and a second magnetic member 142, one of the first magnetic member 141 and the second magnetic member 142 is disposed on the frame 110, and the other is disposed on the optical member 120; the control main board 150 is electrically connected with the first magnetic element 141, when the control main board 150 controls the first magnetic element 141 to be electrified, the first magnetic element 141 can attract or repel the second magnetic element 142 to drive the optical element 120 to move relative to the frame 110, so that the picture is opposite to the pupil of the eyeball.

The optical device 120 includes a left optical device 121 and a right optical device 122, and the left optical device 121 and the right optical device 122 are respectively movably disposed on the frame 110. The display lens 130 includes a left display lens 131 and a right display lens 132, where the left display lens 131 and the right display lens 132 are respectively disposed on the frame 110, the left display lens 131 is used to display a first image projected by the left optical device 121 so as to enable a left eyeball to obtain the first image, and the right display lens 132 is used to display a second image projected by the right optical device 122 so as to enable a right eyeball to obtain the second image, so that the first image and the second image form a 3D image in the brain. The electromagnet assemblies 140 include two groups, each group of electromagnet assemblies 140 including a first magnetic member 141 and a second magnetic member 142.

Since the first magnetic member 141 is electrically connected to the control main board 150, the first magnetic member 141 may be an electromagnet, and the second magnetic member 142 may be an electromagnet, or a magnetic member such as a magnet or a magnet that can generate a magnetic field.

Based on the above structure, when the interpupillary distance adjustment is required, an adjustment command is first given to the control main board 150, and then, the control main board 150 can control the energizing state (i.e. the direction of the energizing current and the magnitude of the energizing current) of the first magnetic member 141 according to the adjustment command, so that the second magnetic member 142 and the first magnetic member 141 adsorb or repel each other to adjust the position of the optical member 120 relative to the frame 110, and further, the picture projected by the optical member 120 to the display lens 130 is opposite to the pupil of the eyeball, so as to complete the interpupillary distance adjustment of the virtual reality glasses 100. Compared with the manual adjustment of the optical element 120 in the related art, in this embodiment, the control main board 150 is used to control the power-on state of the first magnetic element 141 to adjust the pupil distance of the virtual reality glasses 100 in a manner of adjusting the position of the optical element 120 relative to the glasses frame 110, which can not only improve the precision of pupil distance adjustment of the virtual reality glasses 100, but also avoid hardware damage of the virtual reality glasses 100 due to excessive pupil distance adjustment, and ensure the service life of the virtual reality glasses 100.

For example, the virtual reality glasses 100 include an adjustment interface electrically connected to the control main board 150, when a user needs to adjust the interpupillary distance, the user can input an instruction in the adjustment interface, the control main board 150 receives the adjustment instruction and then calculates the magnitude and direction of the current input to the first magnetic element 141, and then the control main board 150 inputs the current with the corresponding magnitude and direction to the first magnetic element 141, so that the first magnetic element 141 generates a magnetic field that repels or attracts the second magnetic element 142, and further the optical element 120 moves a preset distance on the frame 110, so as to complete the adjustment of the interpupillary distance of the virtual reality glasses 100.

Optionally, the control board 150 is fixedly attached to the frame 110 by fasteners (e.g., screws).

In addition, a left battery and a right battery are provided on the frame 110, and are electrically connected to the control main board 150, and also electrically connected to the left optical device 121, respectively.

Because the first magnetic element 141 is disposed on the frame 110, and the frame 110 is fixed, the second magnetic element 142 is a magnet and disposed on the optical element 120, when the optical element 120 needs to be adjusted, the second magnetic element 142 can move close to or far away from the first magnetic element 141, so as to drive the optical element 120 to move close to or far away from the first magnetic element 141, so as to achieve the purpose of adjusting the optical element 120, and as the second magnetic element 142 moves close to or far away from the first magnetic element 141 under the action of the magnetic field generated by the first magnetic element 141, and as the second magnetic element 142 is a magnet, the second magnetic element 142 can avoid the loose or tensioned state of the electric connection wire in the moving process, thereby ensuring the stability of the electric connection of the first magnetic element 141, and further ensuring the stability of the electric connection of the optical element 120.

Of course, the first magnetic member 141 is not limited to an electromagnet, and the first magnetic member 141 may be an electromagnet.

In some possible embodiments, referring to fig. 5, the optical device 120 is provided with a mounting groove 120a, and the second magnetic element 142 is embedded in the mounting groove 120 a.

Optionally, the second magnetic member 142 is adhesively fixed to the mounting groove 120 a. Thereby avoiding damage to light mechanism 120.

In some possible embodiments, referring to fig. 6 and 7, the frame 110 is further provided with a distance detector 160 electrically connected to the control main board 150, and the distance detector 160 is used for detecting a moving distance of the optical member 120, and when the optical member 120 moves a preset distance, the control main board 150 is used for controlling the electromagnet to be powered off.

The distance detector 160 may be a distance sensor, or the like.

Therefore, by setting the distance detector 160, the moving distance of the optical element 120 can be known in time, and when the optical element 120 moves to a preset distance, the control main board 150 can timely control the first magnetic element 141 to be powered off, so that the accuracy of pupil distance adjustment of the virtual reality glasses 100 is ensured.

In addition, the first circuit board and the second circuit board which are electrically connected to the control motherboard 150 are disposed on the frame 110, and the two distance detectors 160 are used for detecting the moving distances of the left optical element 121 and the right optical element 122, and the two distance detectors 160 are disposed on the first circuit board and the second circuit board, and the left optical element 121 and the right optical element 122 are also disposed on the first circuit board and the second circuit board, so that the purpose that the left optical element 121, the right optical element 122, and the two distance detectors 160 are electrically connected to the control motherboard 150 is achieved.

In some possible embodiments, referring to fig. 6 and fig. 7, the frame 110 is further provided with a guiding rail 111, the extending direction of the guiding rail 111 is parallel to the moving direction of the optical device 120, the optical device 120 is provided with a sliding groove 120b, the sliding groove 120b is matched with the guiding rail 111, and the optical device 120 is slidably disposed on the guiding rail 111.

Specifically, the two guide rails 111 include two guide rails 111 having the same extending direction, the left optical element 121 is slidably disposed on one guide rail 111, and the right optical element 122 is slidably disposed on the other guide rail 111, so that the two guide rails 111 can guide the sliding of the left optical element 121 and the right optical element 122 respectively, so as to ensure the consistency of the sliding paths of the left optical element 121 and the right optical element 122.

It can be seen that by providing the guide rail 111, the accuracy of the pupil distance adjustment of the virtual reality glasses 100 is further improved.

In some possible embodiments, referring to fig. 6 and 7, the guiding rail 111 includes two parallel and spaced sliding grooves 120b formed on the optical device 120, and the two sliding grooves 120b are respectively sleeved on the two guiding rails 111.

It should be noted that, the two guide rails 111 include two guide rails 111 corresponding to the left optical device 121 or two guide rails 111 corresponding to the right optical device 122.

Therefore, by arranging two parallel and spaced guide slide rails 111 and two parallel and spaced slide grooves 120b on the optical machine 120, the sliding stability of the optical machine 120 on the guide slide rails 111 can be ensured when the optical machine 120 is matched with the guide slide rails 111, and the pupil distance adjusting effect of the virtual reality glasses 100 is improved.

In addition, the two second magnetic elements 142 are respectively disposed at two opposite ends of the two guiding rails 111, so that when the left optical element 121 and the right optical element 122 respectively move on the two guiding rails 111, the second magnetic element 142 on the left optical element 121 can be prevented from being interfered by the magnetic field of the first magnetic element 141 matching with the second magnetic element 142 on the right optical element 122, and likewise, the second magnetic element 142 on the right optical element 122 can be prevented from being interfered by the magnetic field of the first magnetic element 141 matching with the second magnetic element 142 on the left optical element 121.

In some possible embodiments, referring to fig. 6 and 7, the virtual reality glasses 100 further include a plurality of gear structures 170, the plurality of gear structures 170 being equally spaced along the extension direction of the guide rail 111 to provide a gear feel during movement of the optical device 120 relative to the frame 110.

By providing a plurality of gear structures 170, the gear of light member 120 adjustment can be known in time, and in addition, when light member 120 adjustment is completed, gear structures 170 can limit light member 120 to prevent light member 120 from moving relative to frame 110.

Specifically, when the control main board 150 supplies current of a corresponding magnitude and direction to the first magnetic member 141, the first magnetic member 141 can apply a force to the second magnetic member 142, so as to drive the optical member 120 to slide to a preset gear.

Thus, the image emitted from the optical device 120 is first emitted onto the third surface 130c, then reflected onto the first surface 130a by the third surface 130c, and then reflected onto the third surface 130c by the first surface 130a to be emitted toward the eyeball. Therefore, the light emitted from the light machine 120 can be emitted to the eyeball without arranging too many optical elements.
