Description

Technical Field

[0001] This invention relates to the field of mixed reality, specifically to a mixed reality display device based on an eye tracker. Background Technology

[0002] Mixed Reality (MR) technology is a further development of Virtual Reality (VR) technology. This technology introduces real-world scene information into a virtual environment, creating an interactive feedback loop between the virtual world, the real world, and the user to enhance the realism of the user experience. Generally speaking, the common carrier of VR is smart glasses.

[0003] Currently, the positions of smart glasses on the market are usually fixed. Users need to take off the glasses to occasionally look at the real scene while wearing them, and then put them back on afterward. This process requires adjusting the head strap, which is quite troublesome. Although some glasses can be flipped directly, the two glasses are connected together, and the two glasses can only be flipped together. This does not allow users to view the real scene and the virtual scene at the same time, which reduces the fun. Summary of the Invention

[0004] In response to the problem that existing smart glasses are usually fixed in position, requiring users to remove them to occasionally look at the real scene while wearing them, and then put them back on afterward, which involves adjusting the headband and is quite inconvenient, and that while some glasses can be flipped directly, the two glasses are connected together and can only be flipped together, preventing users from viewing both the real and virtual scenes at the same time, thus reducing the enjoyment, this invention provides a mixed reality display device based on an eye tracker.

[0014] The beneficial effects of this invention are: (1) The mixed reality display device based on an eye tracker described in this invention uses a push rod to drive several connecting rods to move laterally. When the connecting rods move, they will drive the pressing component to move, thereby pressing several third springs. Several magnetic blocks will also separate from the magnetic plate. Then, the pull block is pulled, which drives the limiting rod to move and stretches the first spring. When the limiting rod is completely separated from the positioning groove, the rotating ring can be rotated. The rotating ring rotates along the fixed ring through the inner groove, thereby driving the first and second frames to rotate, so that the user can view the real scene without taking off the glasses, which is more convenient.

[0015] (2) The mixed reality display device based on an eye tracker described in this invention uses a fixed block to press down the extrusion column. When the extrusion column moves down, it will extrude the insertion column. When the insertion column moves down under force, it will extrude the spring. When the insertion column is fully retracted into the mounting slot, the second spring is in a compressed state. Therefore, the slider will move laterally by the restoring force of the second spring, so that the slider slides out of the slot. At this time, the first frame and the second frame are separated. The first frame or the second frame can be flipped according to the user's needs, so that the user's eyes can simultaneously view the real scene and the virtual scene, which is more fun.

A fixing ring 29 is fixedly sleeved on the outside of the bottom end of the first fixing rod 4. Two side blocks 13 are fixedly connected to the side of the first frame 15 near the first fixing rod 4. Both side blocks 13 rotate with the first fixing rod 4. The first frame 15 is connected to the fixing ring 29 via a rotating mechanism 6. The rotating mechanism 6 is connected to both side blocks 13 via connecting blocks 14. The fixing ring 29 has a positioning groove 30 on its outer side. A rotating block 17 is rotatably connected to the outer side of the second fixing rod 10. A second side groove 26 is provided on one side of the rotating block 17. A magnetic plate 27 is fixedly connected to the inner wall of the second side groove 26. A mounting block 18 is fixedly connected to the side of the second frame 16 near the second fixing rod 10. A first side groove 25 is provided on the mounting block 18 corresponding to the position of the second side groove 26. The first side groove 25 has several... A locking mechanism 9 is provided, with several locking mechanisms 9 inserted into the second side groove 26 on one side; a first top block 11 is fixedly connected to the upper end of the first frame 15, and a second top block 12 is fixedly connected to the upper end of the second frame 16. The first top block 11 and the second top block 12 correspond to each other. The upper end of the second top block 12 is provided with a groove 19, and a pressing mechanism 5 is provided in the groove 19. The bottom end of the pressing mechanism 5 is connected to a connecting mechanism 7 through a connecting plate 20. A reset mechanism 8 is provided between the bottom end of the connecting mechanism 7 and the inner wall of the groove 19. A through hole 21 is provided on one side of the bottom end of the groove 19. The bottom end of the first top block 11 is... A slot 32 is provided on one side corresponding to the through hole 21. The connecting mechanism 7 is inserted into the slot 32 through the through hole 21 and the second top block 12. A through groove 23 is provided on the upper end of the first top block 11. The bottom end of the through groove 23 is connected to the slot 32. A pressing post 24 is movably inserted inside the through groove 23. The bottom end of the pressing post 24 is in contact with the connecting mechanism 7. A fixing block 22 is fixedly connected to the top end of the pressing post 24. Users can view the real scene without removing their glasses, which is more convenient. At the same time, it also allows users to view the real scene and the virtual scene with both eyes at the same time, which is more entertaining.

[0021] Specifically, the rotating mechanism 6 includes a rotating ring 61, an inner groove 62, a pull block 63, a first spring 64, and a limiting rod 65. The inner wall of the rotating ring 61 has an inner groove 62. The rotating ring 61 is movably sleeved on the outside of the fixed ring 29 through the inner groove 62. The inner groove 62 is adapted to the fixed ring 29. The limiting rod 65 is movably sleeved with the fixed ring 29. One end of the limiting rod 65 is inserted into the inner groove 62 and engages with the positioning groove 30 on the outside of the fixed ring 29. The other end of the limiting rod 65 is fixedly connected to... Pull block 63, and a first spring 64 is fixedly connected between pull block 63 and the outer wall of rotating ring 61. The first spring 64 is sleeved around the limiting rod 65. Pulling pull block 63 causes the limiting rod 65 to move and stretches the first spring 64. When the limiting rod 65 is completely separated from the positioning groove 30, the rotating ring 61 can be rotated. The rotating ring 61 rotates along the fixed ring 29 through the inner groove 62, thereby driving the first mirror frame 15 and the second mirror frame 16 to rotate.

[0022] Specifically, the pressing mechanism 5 includes a pressing block 51, a pressing rod 52, a fixed cylinder 53, an opening 54, and a sleeve block 55. The fixed cylinder 53 is fixedly connected to the inner wall of the groove 19. The pressing rod 52 is movably inserted into the fixed cylinder 53. The pressing block 51 is fixedly connected to the top of the pressing rod 52. The fixed cylinder 53 has an opening 54 on one side. The sleeve block 55 is fixedly sleeved at the bottom of the pressing rod 52. One side of the sleeve block 55 extends out of the fixed cylinder 53 through the opening 54. The sleeve block 55 is rotatably connected to the upper end of the connecting plate 20. When the first top block 11 is opposite to the second top block 12... Pressing down the pressure rod 52 by the pressure block 51 causes the sleeve block 55 to move down. When the sleeve block 55 moves down, it pushes the slider 71 to move laterally through the connecting plate 20. When the slider 71 moves laterally, it squeezes the second spring 83 through the guide block 82. When the slider 71 is inserted into the slot 32 and the insertion post 74 corresponds to the through slot 23, the insertion post 74 is inserted into the through slot 23 by the restoring force of the spring piece 73, so that the first top block 11 and the second top block 12 are spliced ​​together, and then the first mirror frame 15 and the second mirror frame 16 are spliced ​​together.

[0023] Specifically, the connecting mechanism 7 includes a slider 71, a mounting groove 72, a spring 73, and a post 74. One side of the slider 71 is rotatably connected to the bottom of the connecting plate 20, and the other side of the slider 71 is inserted into the slot 32 through the through hole 21 through the second top block 12. The upper end of the slider 71 located in the slot 32 is provided with a mounting groove 72. A spring 73 is fixedly connected in the mounting groove 72, and a post 74 is fixedly connected to the upper end of the spring 73. The upper end of the post 74 is inserted into the through groove 23 and contacts the bottom end of the pressing column 24. When the pressing column 24 moves down, it will press the post 74. The post 74 moves down under force and will press the spring 73. When the post 74 is completely retracted into the mounting groove 72, the slider 71 will move laterally due to the restoring force of the second spring 83, so that the slider 71 slides out of the slot 32, and at this time, the first mirror frame 15 and the second mirror frame 16 are separated.

[0024] Specifically, the reset mechanism 8 includes a crossbar 81, a guide block 82, and a second spring 83. The guide block 82 is fixedly connected to one side of the bottom end of the slider 71, and the crossbar 81 is fixedly connected inside the groove 19. The bottom end of the guide block 82 is movably sleeved with the crossbar 81. The second spring 83 is fixedly connected between the guide block 82 and the inner wall of the groove 19. The second spring 83 is sleeved around the crossbar 81. The slider 71 is separated from the slot 32 by the restoring force of the second spring 83, thereby separating the first top block 11 from the second top block 12.

[0025] Specifically, each of the locking mechanisms 9 includes a sleeve 91, a third spring 92, a connecting rod 93, a pressing element 94, and a magnetic block 95. The sleeve 91 is fixedly connected to the inner wall of the first side groove 25. The connecting rod 93 is movably inserted into the sleeve 91. The pressing element 94 is fixedly sleeved on the outside of the connecting rod 93. The third spring 92 is fixedly connected between the pressing element 94 and the inner wall of the first side groove 25. The third spring 92 is sleeved around the sleeve 91 and the connecting rod 93. The end of the connecting rod 93 inserted into the second side groove 26 is fixedly connected to the magnetic block 95. The magnetic block 95 is magnetically connected to the magnetic plate 27. The push rod 28 drives the connecting rods 93 to move laterally. When the connecting rods 93 move, they will drive the pressing element 94 to move, thereby pressing the third springs 92. The magnetic blocks 95 will also separate from the magnetic plate 27, thereby releasing the restriction of the second frame 16 and enabling the second frame 16 to be flipped.

[0026] Specifically, soft pads 31 are fixedly connected to the inner sides of the first frame 15 and the second frame 16. Both soft pads 31 are ring-shaped and correspond to the two display mirrors 3 respectively. The soft pads 31 fit snugly against the user's eyes, improving the user's comfort.

[0027] Specifically, a push rod 28 is fixedly connected between several connecting rods 93. The length of the push rod 28 is greater than the length of the mounting block 18. The push rod 28 is designed in a "Z" shape to facilitate the user to push the several connecting rods 93.

[0028] Specifically, a matching bottom ring 33 is fixedly connected to the bottom end of the rotating block 17. The bottom end of the bottom ring 33 has a trapezoidal opening 34. A force-bearing block 35 is fixedly connected to the inner wall of the trapezoidal opening 34. A square block 38 is fixedly connected to the front end of the second fixing rod 10. The square block 38 is located below the bottom ring 33. A bottom block 40 is located below the square block 38. A positioning rod 37 is vertically fixed to the upper end of the bottom block 40. The positioning rod 37 is movably sleeved with the square block 38. A return spring 39 is fixedly connected between the bottom block 40 and the square block 38. The return spring 39 is sleeved around the positioning rod 37. The upper end of the positioning rod 37 is designed in a trapezoidal shape that matches the trapezoidal opening 34. A striking block 36 is fixedly connected to the top of the positioning rod 37. The striking block 36 corresponds to the force-bearing block 35. When the rotating block 17 is not in the designated position, the positioning rod 37 slides out from the trapezoidal opening 34 and contacts the bottom surface of the bottom ring 33. At this time, the return spring 39 is in a stretched state. When the second mirror frame 16 needs to be connected, the rotating block is rotated. When the positioning rod 37 corresponds to the trapezoidal opening 34, the upper end of the positioning rod 37 is inserted into the trapezoidal opening 34 by the force of the return spring 39. At this time, the striking block 36 will also strike the force-bearing block 35. The user can stop rotating the rotating block 17 when he hears the sound. The positioning of the rotating block 17 is more convenient.

[0029] In use, the user wears the two display lenses 3 on their head using the headband 2 and mounting ring 1, with the two display lenses 3 corresponding to the user's eyes. The first lens frame 15 is positioned by the engagement of the limiting rod 65 and the positioning groove 30. The first top block 11 and the second top block 12 are connected by the engagement of the slider 71 and the slot 32, and the insertion post 74 and the through groove 23, thereby connecting the first lens frame 15 and the second lens frame 16. The second lens frame 16 is then positioned by the engagement of several connecting rods 93 and the second side groove 26, and the magnetic connection of several magnets 95 and the magnetic plate 27. When the user needs to flip the glasses to view the real scene, the push rod 28 first moves several connecting rods 93 laterally. When the device moves, it causes the pressing component 94 to move, thereby pressing several third springs 92. Several magnetic blocks 95 will also separate from the magnetic plate 27. Then, the pull block 63 is pulled, which moves the limiting rod 65 and stretches the first spring 64. When the limiting rod 65 is completely separated from the positioning groove 30, the rotating ring 61 can be rotated. The rotating ring 61 rotates along the fixed ring 29 through the inner groove 62, thereby driving the first frame 15 and the second frame 16 to rotate, allowing the user to view the real scene without removing the glasses, which is more convenient. When the user presses down the pressing column 24 through the fixed block 22 to enhance the fun, the pressing column 24 will press the insertion column 74 when it moves down. The insertion column 74 will be pressed down by the force and will press the spring piece 73. When the column 74 is fully retracted into the mounting slot 72, the second spring 83 is under compression, so the slider 71 will move laterally due to the restoring force of the second spring 83, causing the slider 71 to slide out of the slot 32. At this time, the first frame 15 and the second frame 16 are separated. The user can flip the first frame 15 or the second frame 16 according to their needs, allowing the user to view both the real scene and the virtual scene at the same time, which enhances the enjoyment. Since the rotating block 17 is rotatably connected to the second fixing rod 10, the rotating block 17 needs to be rotated in advance when connecting the second frame 16 to the rotating block. The rotating block 17 needs to be rotated to a specific position so that the magnet 95 can be fully inserted into the second side slot 26, thereby completing the positioning and connection of the second frame 16. However, due to the user wearing the glasses... In the current state, it is not easy to rotate the rotating block 17 to the designated position. Therefore, a matching bottom ring 33, trapezoidal opening 34, force block 35, positioning rod 37, return spring 39, and striking block 36 are also provided at the bottom of the rotating block 17. When the rotating block 17 is not in the designated position, the positioning rod 37 slides out from the trapezoidal opening 34 and contacts the bottom surface of the bottom ring 33. At this time, the return spring 39 is in a stretched state. When it is necessary to connect the second mirror frame 16, the rotating block is rotated. When the positioning rod 37 corresponds to the trapezoidal opening 34, the upper end of the positioning rod 37 is inserted into the trapezoidal opening 34 by the force of the return spring 39. At this time, the striking block 36 will also strike the force block 35. The user can stop rotating the rotating block 17 when he hears the sound, which makes the positioning of the rotating block 17 more convenient.
