Description

Technical Field

[0001] The present invention relates to the field of virtual reality technology, and in particular to a device and method for adjusting pupil distance of a VR product. Background Art

[0002] IPD (interpupillary distance) is the measurement of the distance between pupils when looking straight ahead. IPD is crucial for VR products because everyone's IPD is different. The brain will perform 3D calculations based on a specific IPD. If the IPD of the VR user does not match the IPD of the VR itself, this will cause eye fatigue and reduce the user's comfort. Currently, in product testing at the factory end, it is necessary to adjust the product's IPD for optical testing and calibrate the IPD value range.

[0003] Currently, IPD adjustment is mainly done by manually turning the lens barrel of VR products to adjust IPD. However, for VR products with this IPD adjustment method, due to the uncertainty of the product lens barrel position, it is difficult for the testing organization to turn both lens barrels at the same time (turning a single lens barrel will damage the product structure itself). The current solution is mainly to add a visual camera to confirm the exact position of the lens barrel through the camera, but this solution is complex in structure, expensive, and cannot be applied to VR headsets that cannot be removed from the back of the head due to structural size issues. It is not very applicable. The operator manually turns the lens barrel, which increases the test time and the retest rate, and cannot achieve automated testing. So how to use a low-cost, better-structured solution to replace visual cameras or manual operators is an urgent problem to be solved. Summary of the invention

[0004] The main purpose of the present invention is to provide a VR product pupil distance adjustment device and method, aiming to solve the problems of damage to the product structure or complex structure of the adjustment device and high use cost in the pupil distance adjustment of existing VR products.

[0005] To achieve the above-mentioned purpose, the present invention proposes a VR product interpupillary distance adjustment device, including a toggle module, wherein the toggle module includes a support frame, a toggle unit and a toggle drive unit; the toggle unit includes two pressure sensors and two toggle arms spaced apart along a first direction, the two toggle arms extend along a second direction, the two toggle arms are movably arranged on the support frame along the first direction, and have an active stroke of approaching or moving away from each other along the first direction, one end of the two toggle arms is respectively used to synchronously toggle the two lens barrels of the VR product from the side to the top of the lens barrel to adjust the interpupillary distance of the VR product, the two pressure sensors are respectively correspondingly arranged on the two toggle arms, so as to detect the toggle force of the two toggle arms on the corresponding lens barrels; the toggle drive unit is arranged on the support frame, and the toggle drive unit drives the two toggle arms to move.

[0006] Optionally, the toggling drive unit includes a push plate movably mounted on the support frame in the second direction. Two guide grooves are symmetrically and spaced apart in the first direction on the push plate. The two guide grooves extend in the second direction and are both inclined. The other ends of the two toggling arms are provided with engaging portions slidably engaged with the guide grooves. The middle portions of the two toggling arms are movably disposed on the support frame in the first direction. The push plate drives the two toggling arms to move toward or away from each other in the first direction by moving in the second direction.

[0007] Optionally, the support frame is provided with a guide rail extending in the first direction. The middle portions of the two toggling arms are provided with sliding portions slidably engaged with the guide rail.

[0008] Optionally, the engaging portion includes a cam follower disposed at the other end of the toggling arm. The other end of the toggling arm is movably connected to the guide groove through the cam follower.

[0009] Optionally, the toggling drive unit further includes a driving electric cylinder disposed on the support frame. The driving electric cylinder drives the push plate to move.

[0010] Optionally, the VR product interpupillary distance adjustment device includes a frame and a first driving device. The toggling module is movably disposed on the frame through the support frame. The first driving device drives the toggling module to move in the first direction.

[0011] Optionally, the VR product interpupillary distance adjustment device includes a second driving device. The second driving device drives the toggling module to move in the second direction.

[0012] Optionally, the VR product interpupillary distance adjustment device includes a controller electrically connected to the two pressure sensors and the toggling drive unit respectively.

[0013] The present invention also provides a method for adjusting the interpupillary distance of a VR product. Based on the above-mentioned VR product interpupillary distance adjustment device, the method for adjusting the interpupillary distance of the VR product includes:

[0014] Controlling the toggling drive unit to synchronously drive the two toggling arms to move;

[0015] Real-time obtaining the pushing forces of the two toggling arms on the corresponding lens barrels detected by the two pressure sensors;

[0016] Judging the magnitudes of the two pushing forces;

[0017] When the magnitudes of the two pushing forces are different, controlling the first driving device to drive the toggling module to move in the first direction toward the lens barrel corresponding to the smaller pushing force;

[0018] When the magnitudes of the two driving forces are the same, continue to control the driving unit to drive the two driving arms to move synchronously.

[0019] Optionally, after the step of obtaining in real time the driving forces of the two driving arms on the corresponding lens barrels detected by the two pressure sensors, the VR product interpupillary distance adjustment method further includes:

[0020] Judge the magnitude of the driving force and a preset value;

[0021] When the driving force is greater than the preset value, control the first driving device or the driving unit to stop driving.

[0022] In the technical solution of the present invention, the two driving arms are movably arranged on the support frame along a first direction, the support frame can support the two driving arms, and the driving unit drives the two driving arms to move, so that the two driving arms approach or move away from each other along the first direction, so as to synchronously drive the two lens barrels of the VR product from the side of the lens barrels, so that the two lens barrels approach or move away from each other, so as to achieve the purpose of adjusting the interpupillary distance. When the VR product interpupillary distance adjustment device is used, the VR product is fixed so that its two lens barrels are distributed along the first direction. According to actual adjustment needs, one end of the two driving arms extends between the two lens barrels, and is prepared to drive the two lens barrels in the opposite direction from the side of the lens barrels, or one end of the two driving arms is placed outside the two lens barrels, and is prepared to drive the two lens barrels in the same direction from the side of the lens barrels. Start the driving unit to drive the two driving arms to move in a small stroke. Since the positions of the lens barrels of different VR products are different, the two driving arms cannot contact the two lens barrels at the same time at the initial driving position. In this way, the values of the two driving forces detected by the two pressure sensors will be different. According to the values of the two driving forces, judge and let the driving unit drive the two driving arms to move in the direction of the lens barrel corresponding to the smaller driving force until the values of the two driving forces detected by the two pressure sensors are the same. The same value of the two driving forces indicates that the two driving arms are in the middle of the two lens barrels or the two lens barrels are in the middle of the two driving arms. In this way, it is ensured that the two lens barrels can be driven in the opposite direction or in the same direction at the same time, avoiding damage to the lens barrels during unilateral driving. At this time, the accurate driving position is confirmed, and then let the driving unit drive the two driving arms to start moving in a large stroke to synchronously drive the two lens barrels to the set position, completing the adjustment of the interpupillary distance of the VR product. In this way, the two lens barrels of the VR product can be driven at the same time, avoiding damage to the product structure, and the structure is simple and the use cost is low.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, if there are descriptions such as "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.

[0034] IPD (Interpupillary Distance) is the measured value of the distance between the pupils when looking straight ahead. For VR products, IPD is crucial because everyone's IPD is different, and the brain performs 3D calculations based on a specific IPD. If the IPD of the VR user does not match the IPD of the VR itself, this will cause eye fatigue of the user and reduce the comfort of the user. Currently, in the product testing at the factory end, it is necessary to adjust the IPD of the product for optical testing and calibrate the numerical range of the IPD.

[0035] Currently, the IPD adjustment is mainly to manually move the lens barrel of the VR product to adjust the IPD. However, for the VR products with this IPD adjustment method, due to the uncertainty of the position of the product lens barrel, it is very difficult for the testing mechanism to move two lens barrels simultaneously (moving a single lens barrel will damage the structure of the product itself). The current solution is mainly to add a vision camera to confirm the accurate position of the lens barrel through the camera. However, this solution has a complex structure, a high price, and cannot be applied to VRs with non-removable rear headsets due to structural size problems, and its applicability is not high. Moreover, the operator manually moving the lens barrel increases the testing time and the retest rate, and cannot achieve automated testing. Therefore, how to use a solution with low cost and better structure to replace the vision camera or manual operation by the operator is an urgent problem to be solved.

[0036] In view of this, the present invention provides a VR product interpupillary distance adjustment device and method, aiming to solve the problems of damage to the product structure or complex structure and high use cost of the existing VR product interpupillary distance adjustment.

[0037] In the embodiments of the present invention, please refer to Figure 1 and Figure 2The VR product interpupillary distance adjustment device 100 includes a toggle module 10, which includes a support frame 1, a toggle unit 2 and a toggle drive unit 3; the toggle unit 2 includes two pressure sensors 21 and two toggle arms 22 spaced apart along a first direction, the two toggle arms 22 extend along a second direction, the two toggle arms 22 are movably arranged on the support frame 1 along the first direction, and have an active stroke of approaching or moving away from each other along the first direction, one end of the two toggle arms 22 is respectively used to synchronously toggle the two lens barrels of the VR product from the side to the top of the lens barrel to adjust the interpupillary distance of the VR product, the two pressure sensors 21 are respectively correspondingly arranged on the two toggle arms 22, so as to detect the toggle force of the two toggle arms 22 on the corresponding lens barrels; the toggle drive unit 3 is arranged on the support frame 1, and the toggle drive unit 3 drives the two toggle arms 22 to move.

[0038] In the technical solution of the present invention, the two toggle arms 22 are movably arranged on the support frame 1 along a first direction, and the support frame 1 can support the two toggle arms 22. The toggle drive unit 3 drives the two toggle arms 22 to move, so that the two toggle arms 22 are moved closer to or farther away from each other along the first direction, so as to synchronously toggle the two lens barrels of the VR product from the side of the lens barrel, so that the two lens barrels are moved closer to or farther away from each other, so as to achieve the purpose of adjusting the pupil distance. When the VR product pupil distance adjustment device 100 is used, the VR product is fixed so that its two lens barrels are distributed along the first direction. According to actual adjustment needs, one end of the two toggle arms 22 is extended between the two lens barrels, and the two lens barrels are prepared to be reversely toggled from the side of the lens barrel, or one end of the two toggle arms 22 is placed on the outside of the two lens barrels, and the two lens barrels are prepared to be toggled toward each other from the side of the lens barrel. The toggle drive unit 3 is started to drive the two toggle arms 22 to move in a small stroke. Because the positions of the lens barrels of different VR products are different, this leads to the initial At the initial toggling position, the two toggling arms 22 cannot contact the two lens barrels at the same time, so that the values ​​of the two toggling forces detected by the two pressure sensors 21 will be different. According to the values ​​of the two toggling forces, the toggling drive unit 3 drives the two toggling arms 22 to move to move in the direction of the lens barrel corresponding to the smaller toggling force until the values ​​of the two toggling forces detected by the two pressure sensors 21 are consistent. The consistency of the values ​​of the two toggling forces indicates that the two toggling arms 22 are in the middle of the two lens barrels or the two lens barrels are in the middle of the two toggling arms 22. This ensures that the two lens barrels can be toggled in opposite directions or towards each other at the same time to avoid damage to the lens barrels caused by unilateral toggling. At this time, the accurate toggling position confirmation is completed, and then the toggling drive unit 3 drives the two toggling arms 22 to start a large stroke activity to synchronously toggle the two lens barrels to the set position to complete the pupil distance adjustment of the VR product. In this way, the two lens barrels of the VR product can be toggled at the same time to avoid damage to the product structure, and the structure is simple and the use cost is low.

[0039] The present invention does not limit the specific setting of the driving unit. The toggle driving unit 3 may include two linear driving devices, and the two linear driving devices respectively drive the two toggle arms 22 to move. In this embodiment, in order to simplify the mechanism, make the two toggle arms 22 move synchronously, and realize the synchronous and symmetrical toggle of the two lens barrels, the toggle driving unit 3 includes a push plate 31. Specifically, the push plate 31 is movably installed on the support frame 1 along the second direction. The push plate 31 is provided with two guide grooves 311 symmetrically spaced along the first direction. The two guide grooves 311 extend along the second direction and are both inclined. The other ends of the two toggle arms 22 are provided with a matching portion 221 that slidably matches with the guide groove 311. The middle parts of the two toggle arms 22 are movably arranged on the support frame 1 along the first direction. During the movement of the push plate 31 along the second direction, the guide groove 311 obliquely arranged on the push plate 31 also moves along the second direction. The oblique force applied by the push plate 31 to the matching portion 221 of the toggle arm 22 through the guide groove 311 can be decomposed into a force along the second direction and a force along the first direction. Due to the connection constraint between the middle part of the toggle arm 22 and the support frame 1, the support frame 1 has a limiting effect on the toggle arm 22 along the second direction, and the toggle arm 22 can only move along the first direction. Moreover, since the two guide grooves 311 are symmetrically arranged, that is, the inclination slopes of the two guide grooves 311 are the same, the two toggle arms 22 can move the same distance in opposite directions under the drive of the two guide grooves 311, thereby realizing symmetrical distance adjustment of the two lens barrels.

[0040] Furthermore, the support frame 1 is provided with a guide rail 11 extending along the first direction, and the middle parts of the two toggle arms 22 are provided with a sliding part (not shown in the figure) that slidably cooperates with the guide rail 11. In this way, the force applied by the push plate 31 to the toggle arm 22 along the second direction is borne by the guide rail 11, ensuring that the toggle arm 22 moves along the first direction. The toggle arm 22 only has a toggle force on the lens barrel along the first direction, avoiding structural damage to the lens barrel.

[0041] It should be noted that one end of the two toggle arms 22 is used to toggle the two lens barrels of the VR product from the side to the upper side of the lens barrel. This end of the toggle arm 22 is in direct contact with the lens barrel, and the contact portion is contoured so that it can engage with the lens barrel to avoid scratching the product. The contact portion can be set as a detachable contouring tooling to adapt to VR products of different specifications and shapes, thereby improving the applicability of the device.

[0042] The present invention does not limit the specific structure of the mating portion 221 that slidably mates with the guide groove 311, which may be a simple slider. The slider is installed in the guide groove 311 to achieve sliding fit. In this embodiment, in order to reduce friction and improve driving efficiency, the mating portion 221 includes a cam follower 2211 provided at the other end of the toggle arm 22. The other end of the toggle arm 22 is movably connected to the guide groove 311 through the cam follower 2211.

[0043] Further, the toggle driving unit 3 may be a linear driving device for driving the push plate 31 to move, such as a cylinder, a hydraulic cylinder, or a combination of a servo motor and a lead screw. In order to ensure a simple mechanism and achieve precise control, in this embodiment, the toggle driving unit 3 includes a driving electric cylinder 32. The driving electric cylinder 32 is provided on the support frame 1, and the driving electric cylinder 32 drives the push plate 31 to move.

[0044] In this embodiment, the VR product interpupillary distance adjustment device 100 includes a frame 20 and a first driving device 30. The toggle module 10 is movably provided on the frame 20 through the support frame 1. The first driving device 30 drives the toggle module 10 to move along the first direction. In this way, the toggle module 10 can move integrally along the first direction under the drive of the first driving device 30, so that the two toggle arms 22 move synchronously and in the same direction in the first direction, which is convenient for quickly adjusting the entire toggle module 10 to the correct toggle position. Then, the toggle driving unit 3 drives the two toggle arms 22 to synchronously toggle the two lens barrels, which is beneficial to improving the interpupillary distance adjustment efficiency.

[0045] Further, the VR product interpupillary distance adjustment device 100 includes a second driving device 40. The second driving device 40 drives the toggle module 10 to move along the second direction. In this way, the toggle module 10 can be driven to enter and exit the interior of the VR product as a whole, which is convenient for adjusting the interpupillary distance of the VR product.

[0046] It can be understood that the simultaneous setting of the second driving device 40 and the first driving device 30 enables the toggle module 10 to have degrees of freedom of movement along the second direction and the first direction. When adjusting the interpupillary distance, it is beneficial to fix the position of the VR product, and the toggle module 10 as a whole adjusts the position of the lens barrel of the VR product to improve the interpupillary distance adjustment efficiency. The specific settings of the first driving device 30 and the second driving device 40 are not limited. In one embodiment, the first driving device 30 is an electric cylinder for precisely controlling the movement of the toggle module 10 along the first direction, and the second driving device 40 is a cylinder, which is beneficial to controlling costs.

[0047] In this embodiment, the VR product pupil distance adjustment device 100 includes a controller (not shown in the figure), and the controller is electrically connected to the two pressure sensors 21 and the toggle drive unit 3, respectively. In this way, the controller obtains two toggle force information detected by the two pressure sensors 21, and makes a comparison and judgment, thereby controlling the drive of the toggle drive unit 3, improving the intelligence of the VR product pupil distance adjustment device 100, and improving the pupil distance adjustment efficiency. The controller can be a PLC controller, or other controllers, such as a control chip with corresponding functions.

[0048] Specifically, the VR product to be tested is positioned by a special fixture, and the second driving device 40 drives the toggle module 10 to enter the interior of the product and enter a preparatory state. The first step of the toggle adjustment process is to confirm the exact position of the toggle, and the controller controls the driving electric cylinder 32 to drive the push plate 31 to move, and the push plate 31 drives the two toggle arms 22 to move and start to toggle the two lens barrels of the VR product from the side to the top of the lens barrel. Because the positions of the lens barrels of different products are different, the two toggle arms 22 cannot contact the two lens barrels at the initial toggle position at the same time, so that the toggle forces detected by the two pressure sensors 21 corresponding to the two toggle arms 22 will be different. The controller makes a judgment based on the two toggle forces obtained. When the two toggle forces are different in size, the controller controls the second toggle arm 22 to move. A driving device 30 drives the toggle module 10 to move in the direction of the lens barrel corresponding to the smaller toggle force, that is, the entire toggle module 10 moves in a small stroke along the first direction. The controller will make a judgment based on the toggle force information fed back by the two pressure sensors 21 in real time and issue instructions to the first driving device 30 until the toggle forces fed back by the two pressure sensors 21 are consistent in magnitude, and the accurate toggle position is confirmed. After the position is confirmed, the controller issues an instruction to control the driving electric cylinder 32 to start a large stroke to drive the push plate 31 to drive the two toggle arms 22 to synchronously start to toggle the two lens barrels of the product until the lens barrels reach the set position. When the test is completed, the second driving device 40 takes the toggle module 10 out of the product for the next pupil distance adjustment.

[0049] The present invention further provides a method for adjusting the pupil distance of a VR product. Based on the VR product pupil distance adjustment device 100 as described above, the method for adjusting the pupil distance of a VR product comprises:

[0050] S100: Controlling the toggle drive unit to synchronously drive the two toggle arms to move;

[0051] S200: Acquire in real time the pushing force of the two pushing arms on the corresponding lens barrels detected by the two pressure sensors;

[0052] S300: Determine the magnitude of the two pulling forces;

[0053] S410: When the two shifting forces are different in magnitude, controlling the first driving device to drive the shifting module to move along the first direction toward the direction of the lens barrel corresponding to the smaller shifting force;

[0054] S420: When the magnitudes of the two shifting forces are the same, continue to control the shifting drive unit to synchronously drive the two shifting arms to move.

[0055] In this embodiment, by obtaining and judging the two shifting forces to confirm the accurate shifting position, the two lens barrels of the VR product can be shifted at the same time, thus avoiding damage to the product structure and achieving high adjustment efficiency.

[0056] Further, after the step S200 of acquiring in real time the pushing forces of the lens barrels corresponding to the two pushing arms detected by the two pressure sensors, the method for adjusting the pupil distance of a VR product further includes:

[0057] S310: Determine the magnitude of the pulling force and a preset value;

[0058] S430: When the shifting force is greater than the preset value, controlling the first driving device or the shifting driving unit to stop driving.

[0059] In this embodiment, according to the characteristics of the product, a threshold of the lever force that the lens barrel can withstand is preset. When the lever force is greater than the preset value, the first driving device or the lever driving unit is controlled to stop driving to avoid damaging the product and ensure product safety.

[0060] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
