Description

Technical Field

[0001] The present invention relates to the technical field of optical elements, and in particular to a pair of intelligently adjustable virtual reality glasses. Background Art

[0002] Virtual reality glasses use a built-in micro-projector or transparent display to project computer-generated images directly onto the user's eyes, blending them with the real world. This provides a completely new, complete fusion of virtual and real life, enabling a more novel interactive experience and visual perception. Typically, existing virtual reality glasses lack a function to adjust myopia, making it impossible to correct myopia for users with myopia. This is primarily because once you put on the virtual reality glasses, you can't put on your myopia glasses again, making it difficult to achieve optimal results.

[0003] The existing technology also has a myopia function added, which can correct some myopia and improve the viewing effect. However, it adopts a fixed structure, and the relative positions of the two myopia lenses and the virtual reality glasses lenses cannot be adjusted, resulting in the inability to change the pupil distance, which is not suitable for the needs of people with different pupil distances and affects the use effect.

[0004] Even if there is a mechanical adjustment function, it is not very convenient to adjust it when the user wears it on the head. Therefore, a new design is needed, hoping to perform intelligent adjustment so that the user can complete the distance adjustment and focus operation just by wearing it. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a pair of intelligently adjustable virtual reality glasses, which have the function of automatically detecting the pupil distance and automatically adjusting the distance between the lenses, thereby realizing the function of automatically adjusting the pupil distance to achieve a perfect match with the user, so as to enhance the use effect and solve the problem that the existing technology cannot adjust the distance between the lenses and cannot adapt to the use of multiple people.

[0006] The present invention is achieved through the following technical solutions:

[0007] The intelligently adjustable virtual reality glasses include temples, a frame, and an intelligent adjustment system. The temples include temple bodies and an inserting portion connected to the frame. The two inserting portions are identical. The inserting portion includes a disengagement plate arranged on both sides of the width of the temple body and a guide column arranged on the inner side of the disengagement plate. The frame includes a frame, a left mirror body and a right mirror body movably arranged on the left and right sides of the frame, and a driving mechanism arranged between the left mirror body and the right mirror body. The frame is provided with a sliding groove that cooperates with the disengagement plate and a guide hole that cooperates with the guide column. The left mirror body and the right mirror body both include a virtual reality lens and a myopia lens slot stacked on the virtual reality lens. The driving mechanism includes a driving motor fixed to the frame, a driving gear fixed to the main shaft of the driving motor, and two driven racks meshing with the driving gear for transmission. The two One of the driven racks is fixed to the left mirror body, and the other is fixed to the right mirror body. The frame is provided with a mirror body guide groove. The intelligent adjustment system includes a PLC control chip, a high-precision camera, a distance sensor and a measurement drive mechanism. The high-precision camera is used to perform high-definition scanning and imaging of the user's pupil. The distance sensor is used to accurately measure the real-time distance between the distance sensor and the pupil. The measurement drive mechanism is used to drive the distance sensor to move horizontally, thereby determining the deviation value relative to the center of the frame at the closest distance. The sum of the deviation values ​​on the left and right sides is the pupil distance. The PLC control chip is used to set a program to perform corresponding processing and calculation on the camera information and distance information, and to issue adjustment instructions to each drive element, ultimately adapting the lens distance to the pupil distance. The specific adjustment method is as follows:

[0008] S1. Wearing detection: Hold the upper and lower release plates and put the glasses on your eyes. If the total width of the frame is not enough, the release plates will be pulled outward along the sliding groove to increase the total width of the frame. Otherwise, the release plates will be slid inward along the sliding groove to reduce the total width of the frame, thus achieving width adjustment. After the glasses are put on, the high-precision cameras installed on both sides of the frame will perform high-definition scanning and imaging of the user's pupils.

[0009] S2. Distance measurement: The distance sensor is used to accurately measure the real-time distance between the distance sensor and the pupil. At the same time, the distance sensor is driven horizontally by the measurement drive mechanism to determine the closest distance and the deviation value from the center of the frame when the pupil is in the normal view state of a perfect circle. The sum of the deviation values ​​on the left and right sides is the pupil distance;

[0010] S3, information processing: The PLC control chip receives information from the high-precision camera and ranging sensor, processes and calculates the camera information and distance information accordingly, and obtains the pupil distance data;

[0011] S4. Adjustment of mirror distance: The PLC control chip sends adjustment instructions to the drive mechanism based on the calculated pupil distance data, driving the motor to rotate, which in turn drives the drive gear to rotate, and then moves the two driven racks that are engaged with the drive gear to adjust the distance between the left and right mirror bodies, and finally adapt the mirror distance to the pupil distance.

[0012] Furthermore, the drive motor is a double-head drive motor, and the left mirror body and the right mirror body are both provided with driven racks with the same number of teeth and module on the upper and lower sides.

[0013] Furthermore, the high-precision camera and the distance measuring sensor are respectively provided on both sides of the frame.

[0014] Furthermore, two measuring drive mechanisms are provided in the mirror frame, and the measuring drive mechanisms include a sliding groove opened on the mirror frame, a moving seat slidingly matched with the sliding groove, and a moving pole for driving the moving seat to move horizontally. The precision camera and the ranging sensor are fixed on the moving seat, and the moving pole is electrically connected to the PLC control chip.

[0015] Furthermore, through holes for the precision camera and the distance measuring sensor are provided on both sides of the frame.

[0016] Furthermore, a manual knob is fixedly provided on the main shaft of the driving motor, a zero scale pointer mark is provided on the manual knob, and a rotation scale is provided on the periphery of the manual knob.

[0017] Furthermore, there are two guide posts in total, which are spaced apart.

[0018] Furthermore, the inserting portion includes a locking piece fixed to the other side of the decoupling plate, and the bottom of the sliding groove is provided with a locking groove that engages with the locking piece.

[0019] Furthermore, a return spring is provided between the central area of ​​the two engaging parts and the frame, and the length and elastic modulus of the two return springs are exactly the same.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention makes the distance between the temple and the frame adjustable through the interlocking portion, which is suitable for use by different groups of people. More importantly, it creates conditions for accurate measurement of subsequent pupillary distance;

[0022] 2. The present invention provides an adjustable distance between the left and right mirror bodies by movably setting the left and right mirror bodies on the left and right sides of the frame, thereby creating conditions for adjusting the mirror distance;

[0023] 3. The present invention realizes mechanical adjustment of the mirror distance through a driving mechanism, creating conditions for intelligent adjustment of the mirror distance;

[0024] 4. The present invention realizes the purpose of intelligently adjusting the lens distance by automatically imaging the pupil, automatically measuring the pupil distance, and automatically calculating and adjusting the lens distance through the intelligent adjustment system;

[0025] 5. The present invention stacks virtual reality lenses and myopia lenses together to achieve a degree correction function, allowing myopic users to have a virtual and real visual experience.

[0026] 6. By setting the same return spring between the two plug-in parts and the frame, the consistency of the distance between the two plug-in parts and the frame is guaranteed, thereby ensuring the consistency of the center of the frame before and after use, providing guarantee for accurate measurement of pupil distance and focus.

[0027] In summary, the present invention creatively achieves the design goal of intelligently and precisely adjusting the distance between lenses by making the temples and the frame separable and the left and right mirror bodies separable, and by intelligent control. Compared with the existing technology, it does not require more manual adjustment and the adjustment is more precise, greatly enhancing the visual experience of users of virtual reality glasses, especially myopic people.

DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0042] In the above description of the present invention, it should be noted that the terms "one side," "the other side," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0043] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0044] like Figure 1-9As shown, an embodiment of the present invention provides: intelligent adjustable virtual reality glasses, including temples 1, frames 2 and an intelligent adjustment system, the temples including temple bodies 3 and plug-in parts 4, which are inserted and connected to the frame through the plug-in parts to achieve adjustable distance between the temples and the frame, so as to adapt to use by different groups of people, specifically, the plug-in parts include pull-off plates 5 arranged on both sides of the width of the temple bodies and guide posts 6 arranged on the inner sides of the pull-off plates, the frame includes a frame 7, a left mirror body 8 and a right mirror body 9 movably arranged on the left and right sides of the frame, and a driving mechanism arranged between the left mirror body and the right mirror body, the frame is provided with a sliding groove cooperating with the pull-off plate and a guide hole cooperating with the guide post, when in use, the upper and lower pull-off plates are held by the hands and put on the eyes, at this time, if the total width of the frame is not enough, the pull-off plates are withdrawn outward along the sliding groove, thereby increasing the total width of the frame, as shown in FIG. Figure 2 As shown, on the contrary, it is necessary to slide the pull-off plate inward along the sliding groove to reduce the total width of the frame, such as Figure 1 As shown, the purpose of width adjustment is achieved. The process can be easily implemented and does not require complicated operations.

[0045] In particular, both the left and right mirror bodies include a virtual reality lens 10 and a myopia lens slot 11 stacked on the virtual reality lens. The myopia lens slot can be inserted with myopia lenses of different degrees as needed to adapt to use by different groups of people. The myopia lens slot is stacked with the virtual reality lens, that is, the user can expand and adjust the field of vision and enter the human visual nerve, thereby obtaining a clear visual experience, which enhances the use effect of myopic people.

[0046] The driving mechanism of this embodiment includes a driving motor 12 fixed on the frame, a driving gear 13 fixed on the main shaft of the driving motor and two driven racks 14 meshing with the driving gear. One of the two driven racks is fixed to the left mirror body, and the other is fixed to the right mirror body. The frame is provided with a mirror body guide groove 15. The driving motor rotates and the driving gear rotates, thereby driving the driven racks to move. When the total length of the two driven racks is shortened, the left mirror body and the right mirror body approach each other, the distance between them is shortened, and the mirror distance is shortened. Conversely, when the total length of the two driven racks increases, the left mirror body and the right mirror body move away from each other, and the mirror distance increases.

[0047] The intelligent adjustment system of this embodiment includes a PLC control chip 16, a high-precision camera 17, a distance sensor 18 and a measurement drive mechanism. The PLC control chip is electrically connected to the high-precision camera, the distance sensor and the measurement drive mechanism. The high-precision camera is used to perform high-definition scanning and imaging of the user's pupil. The distance sensor is used to accurately measure the real-time distance between the distance sensor and the pupil. The measurement drive mechanism is used to drive the distance sensor to move horizontally, thereby determining the deviation value relative to the center of the frame at the closest distance. The sum of the deviation values ​​on the left and right sides is the pupil distance. The PLC control chip is used to set a program to perform corresponding processing and calculation on the camera information and distance information, and to issue adjustment instructions to each drive element based on the calculated pupil distance, thereby adjusting the distance between the two mirror bodies, and ultimately adapting the mirror distance to the pupil distance.

[0048] In this embodiment, the drive motor is a double-headed drive motor, and both the left mirror body and the right mirror body are provided with driven racks with the same number of teeth and module on the upper and lower sides, so as to drive from both sides, making the movement smoother and the wear less.

[0049] In this embodiment, a high-precision camera and a ranging sensor are arranged on each side of the frame, and two measuring drive mechanisms are provided in the frame. The measuring drive mechanism includes a sliding groove 19 opened on the frame, a moving seat 20 slidingly matched with the sliding groove, and a moving pole 21 for driving the moving seat to move horizontally. The precision camera and the ranging sensor are fixed on the moving seat, and the moving pole is electrically connected to the PLC control chip.

[0050] During specific measurement, the user puts on the glasses, the PLC control chip automatically issues a measurement command, the mobile pole is started, and the moving base, precision camera, and distance sensor are pushed to move simultaneously. At this time, the camera scans and images the pupils on each side in real time, and at the same time, the distance sensor also measures the distance between the measuring lens and the pupil in real time. When the pupil imaged by the camera is a perfect circle, it is determined to be in the emmetropia state, and is further confirmed by the distance sensor. At this time, the distance between the measuring lens and the pupil is the shortest, which further confirms that the eyeball is in the emmetropia state, and records the horizontal coordinate at this time. The deviation value relative to the center of the frame, and the sum of the deviation values ​​on the left and right sides is the pupil distance.

[0051] The horizontal coordinates of this embodiment can be accurately measured using a spatial positioning instrument, or can be converted using the real-time extension of the mobile pole.

[0052] In particular, in order to ensure that the center of the frame remains unchanged, a return spring 27 is provided between the central area of ​​the two interlocking parts and the frame in this embodiment. The length and elastic modulus of the two return springs are exactly the same. When the user wears the glasses, the spring restoring forces at both ends of the frame are exactly the same, and when the interlocking parts are also exactly the same, the action force and reaction force between the frame and the two ends are also exactly the same. Therefore, the elongation relative to the two ends of the frame is exactly the same, thereby ensuring the consistency of the frame center before and after use, and further ensuring the accuracy of the deviation value and the accuracy of the pupil distance.

[0053] In this embodiment, through holes 22 for the precision camera and the distance measuring sensor to see through are provided on both sides of the frame. The through holes facilitate the passage of light and ultrasonic waves without attenuation, thereby improving the measurement accuracy.

[0054] In this embodiment, a manual knob 23 is fixedly provided on the main shaft of the driving motor, a zero scale pointer mark is provided on the manual knob, and a rotation scale 24 is provided on the periphery of the manual knob. The mirror distance can also be adjusted by the manual knob.

[0055] In this embodiment, two guide posts are provided and are spaced apart from each other, thereby improving the stability of the guide.

[0056] In this embodiment, the insertion part also includes a locking piece 25 fixed on the other side of the release plate, and a locking groove 26 is provided at the bottom of the sliding groove to engage with the locking piece. Through the cooperation between the locking piece and the locking groove, the cooperation accuracy between the two is further improved, and it is not easy to slide out, thereby increasing reliability and safety.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
