The base 1 is used to support and install the first optical module 2 and the second optical module 3, and the first optical module 2 and the second optical module 3 are used to collect image data.

[0022] The automatic pupil distance adjustment device 100 further includes a pupil distance collection assembly 20, a transmission assembly 7 supported on the base 1 to form a rotational connection with the base 1 and positioned between the first optical module 2 and the second optical module 3, a pupil distance adjustment drive circuit, and a processor (not shown), wherein both ends of the transmission assembly 7 are rotationally connected to the sides of the first optical module 2 and the second optical module 3 that are closer to the base 1, respectively, the processor is electrically connected to the pupil distance adjustment drive circuit and the pupil distance collection assembly 20, respectively, and the pupil distance adjustment drive circuit is electrically connected to the transmission assembly 7.

[0023] The first pupil position collecting assembly 20 is used to collect pupil images displayed on the first optical module 2 and the second optical module 3 and transmit them to the processor.

[0024] The processor is used to receive the pupil image and calculate and obtain pupil position size and interpupillary position information.

[0025] The adjustment drive circuit receives the pupil distance position information fed back from the processor and drives the transmission connection of the transmission assembly 7 to move the first optical module 2 and the second optical module 3 closer to or farther away from each other on the base 1, thereby adjusting the pupil distance between the first optical module 2 and the second optical module 3. In this way, in the field of smart wear VR, the automatic pupil distance adjustment device 100 can be adapted to all user groups, and the appearance of the product does not require additional IPD adjustment components such as knobs, improving the product's appearance integrity and reducing the difficulty of product assembly. At the same time, for different customer groups, the device can quickly identify user IPD dimensions and quickly and automatically further adapt based on the different IPDs, improving left and right eye image capture and enhancing the user experience.

[0026] In this embodiment, the pupil position collecting assembly 20 includes a first pupil position collector 4 fixed to the first optical module 2 and a second pupil position collector 5 fixed to the second optical module 3, the pupil image includes a first pupil image displayed on the first optical module 2 and a second pupil image displayed on the second optical module 3, the first pupil position collector 4 is used to collect and transmit the first pupil image to the processor, and the second pupil position collector 5 is used to collect and transmit the second pupil image to the processor. The first pupil image displayed on the first optical module 2 and the second pupil image displayed on the second optical module 3 are collected via the first pupil position collector 4 and the second pupil position collector 5, respectively, and transmitted to a processor. The processor receives the first pupil image and the second pupil image, respectively, and calculates and obtains pupil position dimension and pupil distance position information. The adjustment driving circuit receives the pupil distance position information fed back by the processor and drives the transmission member to move the first optical module 2 and the second optical module 3 closer to or farther away from each other on the base 1, thereby adjusting the pupil distance between the first optical module 2 and the second optical module 3 and achieving pupil distance adjustment.

[0027] In this embodiment, the base 1 includes a base main body 11 and a plurality of fixed seats 12 formed by extending and protruding from the base main body 11 in a direction approaching the first optical module 2 and the second optical module 3, the first optical module 2 includes a first optical unit 21 and a plurality of first sliding seats 22 fixed to the side of the first optical unit 21 approaching the base 1 and spaced apart from each other, and the second optical module 3 includes a second optical unit 31 and a plurality of second sliding seats 32 fixed to the side of the second optical unit 31 approaching the base 1 and spaced apart from each other.

[0028] The automatic pupil distance adjusting device 100 further includes an adjustment shaft 8 extending along the movement direction of the first optical module 2 and the second optical module 3 and arranged opposite to each other. The adjustment shaft 8 passes through the fixed seats 12 to form a fixed support, and the first sliding seats 22 and the second sliding seats 32 are both fitted onto the adjustment shaft 8 to form a sliding connection. The fixed seats 12 are fixedly connected to the adjustment shaft 8, and the first sliding seats 22 and the second sliding seats 32 are respectively slidably connected to the adjustment shaft 8. This reduces friction during the sliding of the first optical module 2 and the second optical module 3, making it easy to adjust the distance between the first optical module 2 and the second optical module 3. A transmission assembly 7 drives the first optical module 2 and the second optical module 3 to slide back and forth on the base 1 along the adjustment shaft 8, allowing for quick identification of the user's interpupillary distance (IPD) and quick and automatic adjustment based on different IPDs, improving left and right eye imaging and enhancing the user experience.

[0029] Specifically, there are two sets of fixed seats 12, with three in each set and aligned in a straight line, and two sets of four in each set and aligned in a straight line. There are four first sliding seats 22, with two of them spaced apart. There are four second sliding seats 32, with two of them spaced apart.

[0030] Specifically, the adjusting shaft 8 is made of steel material, and has high structural strength and a long service life.

[0031] In this embodiment, the transmission assembly 7 includes a transmission member 6 fixed to the base 1, a worm wheel 71 rotatably mounted on the base 1, a first connecting pillar 72 and a second connecting pillar 73 formed to protrude from the side of the worm wheel 71 away from the base 1 and spaced apart from each other, a first connecting rod 74, and a second connecting rod 75, and the transmission member 6 is transmission-connected to the worm wheel 71, one end of the first connecting rod 74 is connected to the first connecting pillar 72, the other end of the first connecting rod 74 is connected to the side of the first optical module 2 closest to the base 1, one end of the second connecting rod 75 is connected to the second connecting pillar 73, and the other end of the second connecting rod 75 is connected to the side of the second optical module 3 closest to the base 1. By driving the rotation of the worm wheel 71 via the transmission member 6, the first connecting rod 74 and the second connecting rod 75 move accordingly on the worm wheel 71, and the first optical module 2 and the second optical module 3 are pushed and pulled closer to or farther apart via the first connecting rod 74 and the second connecting rod 75, respectively, thereby realizing automatic adjustment of the pupil distance of the first optical module 2 and the second optical module 3.

[0032] In this embodiment, the connection position of the other end of the first connecting rod 74 and the connection position of the other end of the second connecting rod 75 are on the same straight line parallel to the adjustment axis 8. As a result, the first optical module 2 and the second optical module 3 move at the same position and have the same moving position and distance when the transmission member 6 drives the rotation of the worm wheel 71.

[0033] In this embodiment, the first connecting post 72 and the second connecting post 73 are installed symmetrically with respect to the center of the worm wheel 71. Therefore, the first connecting rod 74 and the second connecting rod 75 move to the same position and distance during the rotation of the worm wheel 71.

[0034] In this embodiment, the transmission member 6 includes a drive unit fixed to the base 1 and a worm 61 fixedly connected to the output end of the drive unit, and the worm 61 meshes with the worm wheel 71. The drive unit drives the rotation of the worm 61 to drive the rotation of the worm wheel 71, thereby driving the first connecting rod 74 and the second connecting rod 75 to perform left and right push-pull reciprocating motions, and the first connecting rod 74 and the second connecting rod 75 respectively drive the first optical module 2 and the second optical module 3 to displace along the adjustment axis 8, thereby completing the IPD automatic adjustment function.

[0035] In this embodiment, the base 1 further includes a recessed groove 13 penetrating therethrough, and the side of the worm 61 adjacent to the base 1 is suspended within the recessed groove 13. This facilitates the recessed installation of the worm 61 and saves the overall installation space.

[0036] In this embodiment, the first optical unit 21 includes a first display screen assembly 211, a first barrel bracket 212 fixed to the side of the first display screen assembly 211 away from the base 1, a first lens group 213 fixed in the first barrel bracket, a first adjustment ring 214 fitted onto the outside of the first barrel bracket 212, and a first infrared lamp ring 215 fixed to the cover of the side of the first barrel bracket 212 away from the base 1. Rotating the first adjustment ring 214 drives the first lens group 213 to rotate and move up and down, thereby adjusting the distance between the first lens group 213 and the first display screen assembly 211, thereby realizing manual adjustment of the refractive power effect of the first optical unit 21. A plurality of guide grooves 9 are formed penetrating the side wall of the first lens barrel bracket 212, and a plurality of position limiting grooves 111 are respectively recessed and formed inside the first adjustment ring 214, with the number of guide grooves 9 and the number of position limiting grooves 111 being the same. A plurality of shift levers are respectively protrudingly formed on the outer periphery of the first lens group 213, and are connected to the position limiting grooves 111 by penetrating the guide grooves 9. By rotating the first adjustment ring 214 and pushing the shift levers, the first lens group 213 rotates and moves up and down along with the guide grooves 9, thereby adjusting the distance between the first lens group 213 and the first display screen assembly 211 and achieving refractive power adjustment.

[0037] Two seal rings 10 are further installed between the first adjustment ring 214 and the first lens barrel bracket 212 to improve the sealing performance between the first adjustment ring 214 and the first lens barrel bracket 212. The seal rings 10 are O-shaped seal rings 10 and have good sealing performance.

[0038] The second optical unit 31 includes a second display screen assembly 311, a second lens barrel bracket 312 fixed to the side of the second display screen assembly 311 facing away from the base 1, a second lens group 313 fixed within the second lens barrel bracket 312, a second adjustment ring 314 fitted onto the second lens barrel bracket 312, and a second infrared lamp ring 315 fixed to the side of the second lens barrel bracket 312 facing away from the base 1. Rotating the second adjustment ring 314 drives the second lens group 313 to rotate and move up and down, thereby adjusting the distance between the second lens group 313 and the second display screen assembly 311, thereby manually adjusting the refractive power of the second optical unit 31. Since the first optical unit 21 and the second optical unit 31 have the same structure, the same principle is also used, and a detailed description thereof will be omitted here.

[0039] Specifically, the first infrared lamp ring 215 and the second infrared lamp ring 315 are LED (Light-Emitting Diode Light) lamp rings.

[0040] Example 2 As shown in Figures 1 to 7, an embodiment of the present invention further provides a method for automatically adjusting pupil distance, which is used in the automatic pupil distance adjustment device 100 of the above-mentioned embodiment 1 and includes steps S1 to S5.

[0041] In S1, the processor receives the first pupil image collected by the first pupil position collector 4 and the second pupil image collected by the second pupil position collector 5, respectively, and converts the first pupil image and the second pupil image into adjustment drive information.

[0042] In S2, the adjustment drive information is fed back to the pupil distance adjustment drive circuit.

[0043] In S3, the pupil distance adjustment drive circuit drives the transmission member 6 to operate.

[0044] In S4, the transmission member 6 drives the rotation of the worm 61, the worm 61 drives the rotational movement of the worm wheel 71, and the worm wheel 71 drives the first connecting rod 74 and the second connecting rod 75 to perform reciprocating push-pull motion, respectively, so that the first optical module and the second optical module slide along the adjustment axis to move closer to or farther away from each other, thereby adjusting the pupil distance of the first optical module 2 and the second optical module 3 and realizing the pupil distance adjustment function.

[0045] In S5, when the image output from the pupil position collector reaches a preset clarity, the processor controls the transmission member 6 to stop.

[0046] Specifically, when a user wears the VR glasses, the first pupil image and the second pupil image acquired through the first pupil position collector 4 and the second pupil position collector 5 are sent to the processor, respectively. The processor calculates the pupil position dimension and pupil distance position information based on the pupil position and the eyeball reflected infrared LED position, and feeds back the IPD data to the IPD adjustment drive circuit.

[0047] When the device wearing sensor confirms that the device is in the predetermined position, the first pupil position collector 4 and the second pupil position collector 5 start transmitting pupil position images. The processor calculates pupil position information and feeds the IPD data back to the IPD adjustment drive circuit, which drives the micromotor to rotate and drives the worm of the input shaft to rotate, which in turn drives the adjustment worm wheel 71 including the IPD. The worm wheel 71 drives the first connecting rod 74 (left connecting rod) and the second connecting rod 75 (right connecting rod) to perform reciprocating push-pull motions. The first connecting rod 74 and the second connecting rod 75 respectively drive the first optical module 2 and the second optical module 3 to displace along the pupil distance adjustment axis 8, thereby completing the automatic IPD adjustment. In the field of smartwear VR, the automatic pupil distance adjustment device 100 can be adapted to all user groups, and the appearance of the product does not require additional IPD adjustment parts such as knobs, improving the appearance integrity of the product and reducing the difficulty of product assembly. At the same time, for different customer segments, the device can also quickly identify user IPD dimensions and quickly and automatically adapt based on different IPDs, improving left and right eye imaging and improving user experience.

[0048] Compared with the prior art, in the automatic pupil distance adjusting device of the present invention, both ends of a transmission assembly are rotatably connected to the sides of the first optical module and the second optical module that are closest to the base, a processor is electrically connected to a pupil distance adjustment driving circuit and a pupil position collecting assembly, and the pupil distance adjustment driving circuit is electrically connected to the transmission assembly, and the pupil position collecting assembly is used to collect pupil images displayed on the first optical module and the second optical module and transmit them to the processor, and the processor is used to receive the pupil images and calculate and obtain pupil position dimensions and pupil distance position information, and the adjustment driving circuit is used to receive pupil distance position information fed back from the processor and drive the transmission connection of the transmission assembly to drive the first optical module and the second optical module to move closer to or farther away from each other on the base, thereby adjusting the pupil distance between the first optical module and the second optical module and realizing pupil distance adjustment. In the field of smart wear VR, the automatic pupil distance adjustment device can be adapted to all user groups, and the appearance of the product does not need to add IPD adjustment parts such as knobs, improving the completeness of the product appearance and reducing the difficulty of product assembly. At the same time, for different customer groups, the device can adjust automatically instead of manually, quickly check the user's IPD size, and quickly and automatically adapt based on different IPDs, improving left and right eye imaging and improving the user experience.

[0049] The above is only an embodiment of the present invention, and those skilled in the art may make various modifications without departing from the creative concept of the present invention, all of which are included in the scope of protection of the present invention.
