Description
Technical Field
[0001] The present invention relates to the field of VR, and in particular to a VR interactive experience device. Background Art
[0002] VR glasses, as the core equipment of virtual reality technology, are head-mounted displays that can create an immersive three-dimensional environment experience for users. They present slightly different images to the left and right eyes respectively, and combined with head tracking technology, make users feel as if they are in a virtual, interactive three-dimensional world. They are widely used in game entertainment, education and training, real estate display and other fields to provide users with an immersive experience.
[0003] When the interpupillary distance of VR glasses does not match that of the user, the images on the screens of both eyes will overlap, resulting in slight double vision. In severe cases, dizziness and nausea may occur. Therefore, in order to ensure that users can get the clearest visual experience when using VR glasses, VR glasses are usually equipped with an interpupillary distance adjustment function. At present, most VR glasses on the market have manually adjusted interpupillary distance. Manual adjustment of interpupillary distance usually needs to be achieved through physical knobs or sliders. The adjustment process requires users to make precise adjustments based on their own interpupillary distance. When used by one person, it usually only needs to be adjusted once, which is relatively convenient. However, when multiple people share the same device, since each person's interpupillary distance is different, it is necessary to frequently adjust the interpupillary distance. This is not only cumbersome to operate, but also affects the user experience and reduces the practicality and flexibility of the device.
[0004] Therefore, we make improvements to this and propose a VR interactive experience device. Summary of the invention

DETAILED DESCRIPTION
[0020] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0021] The present invention will be further described below in conjunction with the embodiments.
[0022] For examples, please refer to Figure 1 , comprising a VR glasses body 100, the VR glasses body 100 having a mirror housing 101 and a pair of lens components 102 movably arranged at the inner end of the mirror housing 101, a limiting frame plate 103 being provided on the inner side of the mirror housing 101, a pair of first movable notches 104 for linear movement of the lens component 102 being provided on the limiting frame plate 103, and a sealing plate 105 being in sliding contact with the limiting frame plate 103 and covering the first movable notches 104 at the inner end of the lens component 102; This application mainly solves the problem that when multiple people share the same VR glasses device, they need to frequently adjust the pupil distance to adapt to the user's own, which is cumbersome to operate, has a poor experience, and reduces the practicality and flexibility of the device. Therefore, the structure of controlling the displacement of the lens component 102 in the VR glasses body 100 is mainly improved; For details, please refer to Figures 1 to 4, including a sliding assembly 200 for adjusting the distance between the two lens components 102, the sliding assembly 200 includes a transmission belt 201 and a transmission rod 202 installed in the mirror housing 101, the transmission rod 202 is connected to the transmission belt 201 through a first transmission structure, the first transmission structure includes a half gear 204 installed at the end of the transmission rod 202 and a rack 205 fixed on the transmission belt 201 and meshing with the half gear 204, the two lens components 102 are respectively fixed on both sides of the transmission belt 201 and move synchronously with the transmission belt 201 Linear motion in the forward or reverse direction, specifically, guide rods 106 are provided at the four corners in the mirror housing 101, first guide wheels 203 are installed on the guide rods 106, a transmission belt 201 is adapted to be installed on the four first guide wheels 203, and the transmission belt 201 is installed in the mirror housing 101 in a rectangular shape, and a connecting seat 107 for fixing with the transmission belt 201 is adapted to be provided on the two lens components 102, that is, one connecting seat 107 is located at the upper end of the lens component 102, and the other is located at the lower end of the corresponding lens component 102; The transmission rod 202 drives the transmission belt 201 to move unidirectionally, and the belt body parts on the upper and lower sides thereof can drive the corresponding two lens components 102 to perform synchronous linear motion in opposite directions (closer or farther away), thereby adjusting the distance between the two lens components 102; Please refer to Figures 2 to 6 , further, it also includes a multi-stage adjustment component 300 for adjusting the distance between the two lens components 102 according to the user's pupil distance, the adjustment component includes a group of pull ropes 301 elastically arranged in the mirror housing 101 and the outer ends extending to the outside of the mirror housing 101, the ends of the pull ropes 301 have corresponding pull rings, which are convenient for user operation, and the pull rings are located at the bottom of the mirror housing 101 to improve the appearance of the device, and the middle part of each pull rope 301 is independently connected to the transmission rod 202 through the second transmission structure, and a limit block 302 is also fixed on the pull rope 301, and a group of limit plates 303 for limiting the moving distance of the corresponding limit block 302 are movably arranged in the mirror housing 101; like Figure 4 and Figure 5 As shown in the figure, the second transmission structure includes a driven plate 308 installed on the transmission rod 202, and a group of second movable slots 309 for the pull rope 301 to pass through independently are opened on the driven plate 308. The second movable slots 309 are linear slots, so that when the driven plate 308 rotates with the transmission rod 202, the pull rope 301 continues to make linear motion. Each pull rope 301 is fixed with a sliding block 310 located on one side of the driven plate 308. Preferably, the sliding block 310 includes a shaft body, and both ends of the shaft body are rotatably provided with pulleys 311 that contact the driven plate 308, and the pull rope 301 passes through and is fixed on the shaft body.
[0023] In specific implementation, each elastic pull rope 301 corresponds to a user. When using it for the first time, the user adjusts the position of the corresponding limit plate 303 according to the pupil distance that suits him / her, that is, the distance between the limit plate 303 and the limit block 302. In this application, the transmission belt 201 is driven to make corresponding movements by pulling the length of the pull rope 301, so controlling the displacement of the pull rope 301 can correspondingly control the distance between the two lens components 102. The specific process of the pull rope 301 driving the transmission belt 201 to make corresponding movements is: when the user pulls the corresponding pull rope 301, the pull rope 301 drives the sliding block 310 to make linear motion synchronously, thereby squeezing the driven plate 308 to rotate, thereby driving the transmission rod 202 and the half gear 204 to rotate synchronously, and through the engagement of the half gear 204 with the rack 205, the transmission belt 201 is driven to make corresponding movements.
[0024] By limiting the displacement of the pull rope 301 by the limit plate 303, when multiple users use it alternately, the user only needs to pull the corresponding pull rope 301 until the limit block 302 contacts the limit plate 303, and the two lens components 102 can be adjusted to suit their own pupil distance. There is no need to wear the VR glasses body 100 to adjust the pupil distance of the two lens components 102. The operation is quick and convenient, and it is suitable for use scenarios with multiple members such as small groups or families, which improves the practicality and flexibility of the device.
[0025] It can be understood that in the present application, the distance between the two lens components 102 is adjusted by the unidirectional movement of the transmission belt 201, and because multiple user members use it in sequence, the operation of adjusting the distance between the two lens components 102 is also relatively frequent. Therefore, after each use, the distance between the two lens components 102 is reset to the minimum value, such as Figure 1 As shown in , the distance between the two lens components 102 can be adjusted to accommodate multiple users' respective operations.
[0026] Please refer to Figure 2 and Figure 6 The bottom of the mirror housing 101 is provided with a group of threaded rods 312 corresponding to the pull rope 301, and the ends of the threaded rods 312 are provided with knobs 313 for controlling the rotation of the threaded rods 312. The mirror housing 101 is provided with a group of third movable slots 314. The bottom end of the limiting plate 303 passes through the third movable slot 314 and is threadedly matched with the threaded rods 312. The top of the limiting plate 303 is provided with a groove 315 for the pull rope 301 to pass through. The third movable slot 314 is a linear slot, so the limiting plate 303 is also linearly limited. Therefore, under the operation of rotating the knob 313, the threaded rod 312 rotates synchronously, and correspondingly, the limiting plate 303 is driven to make corresponding displacement, so as to achieve the purpose of adjusting the distance between the limiting plate 303 and the limiting block 302. In the initial use state, each user member only needs to adjust the position of the limit plate 303 according to the distance between the two lens components 102 that he or she adapts to. The specific operation is that the user first pulls the corresponding pull rope 301 to adjust the relative position of the two lens components 102. After adapting to his or her own pupil distance, he or she rotates the knob 313 corresponding to the pull rope 301 to make the limit plate 303 contact with the limit block 302. In this way, when using it in the future, the user only needs to pull the pull rope 301 until it can no longer be pulled. Correspondingly, the distance between the two lens components 102 is also adjusted accordingly in this process. The structure is simple and the operation is fast and convenient.
[0027] Please refer to Figure 5 and Figure 6 Furthermore, a second guide wheel 304 for the pull rope 301 to bypass is installed on the guide rod 106 to facilitate the linear movement of the pull rope 301 at the driven plate 308. A group of fixed plates 305 are centrally symmetrically arranged in the mirror housing 101. The inner end and the middle of the pull rope 301 are respectively provided with fixed blocks 306 corresponding to the fixed plates 305. A reset spring 307 is fixed between the fixed block 306 and the corresponding fixed plate 305 for resetting the pull rope 301 (and the transmission belt 201) for use by other members. Among them, the fixed block 306 at the bottom is a limit block 302 opposite to the limit plate 303, so that the above-mentioned middle limit plate 303 and other related structures are arranged at the bottom of the VR glasses body 100 to improve the appearance of the device.
[0028] Please refer to Figures 2 to 5 and Figure 7 Considering the situation that the device is used alternately by multiple users, a limit assembly 400 is also provided in the present application to limit the transmission rod 202 to unidirectional rotation when powered on and bidirectional rotation when powered off. That is, when the device needs to be used, the user can quickly pull the pull cord 301 to use it in the powered on state. Due to the limitation of unidirectional rotation of the transmission rod 202, the pull cord 301 will not be affected by the reset spring 307 and move back. Correspondingly, in the power-off state, the use of the next user needs to be considered at this time, so the transmission belt 201 is required to drive the two lens components 102 to reset. Therefore, when the power is off, the transmission rod 202 can be reversed and automatically reset with the reset of the pull cord 301, and the two lens components 102 are driven to reset during the reset process.
[0029] Specifically, it includes a ratchet mechanism installed between one end of the transmission rod 202 and the mirror housing 101, wherein the ratchet mechanism has an elastic ratchet 401 slidably arranged in the mirror housing 101, and the ratchet mechanism also includes a ratchet plate 403 installed at the outer end of the transmission rod 202, and the ratchet plate 403 has a ratchet groove 404 adapted to the elastic ratchet 401. A positioning seat 405 is installed on the top of the inner cavity of the mirror housing 101, and a slide seat 406 is elastically slidably arranged on the positioning seat 405. Preferably, a slide bar is provided on the positioning seat 405, and the slide seat 406 is interlaced and connected with the slide bar to achieve the purpose of linear movement of the seat. The slide seat 406 and the positioning seat 405 are reset by an elastic member, and the elastic ratchet 401 is installed on the slide seat 406 and is adapted to be snap-fitted with the ratchet groove 404. A power-off type electromagnet 407 is also installed on the positioning seat 405, and the power-off type electromagnet 407 is connected to the The power supply of the VR glasses body 100 is electrically connected, and a corresponding magnetic attraction member 408 is arranged on the slide 406, wherein the de-energized electromagnet 407 relies on the built-in permanent magnet to maintain the attracted state in the power-off state, and overcomes the effect of the permanent magnet when powered on, thereby realizing release or other operations. Specifically, in the present application, in the power-on state, the magnetic attraction member 408 is not affected by the de-energized electromagnet 407, and then the elastic ratchet 401 can be engaged with the ratchet plate 403 under the action of the elastic member, so as to limit the unidirectional rotation of the ratchet plate 403 and the transmission rod 202. On the contrary, in the power-off state, the de-energized electromagnet 407 generates suction on the magnetic attraction member 408, so that the slide 406 is separated from the ratchet plate 403 with the elastic ratchet 401, and then the ratchet plate 403 and the transmission rod 202 can be reversely rotated and reset.
[0030] Furthermore, a reset spring 402 is installed between the inner end of the transmission rod 202 and the mirror housing 101, and the inner side of the half gear 204 has an installation groove for installing the reset spring 402. When the power is off, the transmission rod 202 is reset by releasing the elastic force of the reset spring 402, thereby driving the transmission rod 202 to reverse, so that the transmission belt 201 drives the two lens components 102 to reset.
