Description

Technical Field

[0001] This application relates to the technical field of VR glasses, and particularly to a magnetically-attached and quickly-detachable VR headset device. Background Art

[0002] A VR headset, namely a VR glasses, can provide a 360-degree immersive visual experience for the wearer; as the main carrier of VR technology, the performance and usage experience of VR glasses directly affect the user's perception and usage effect.

[0003] Currently, most VR glasses are worn by using an integrated bandage or a Velcro headband. For VR glasses with an integrated bandage, the user needs to spread the integrated bandage and put it on the head. For users with hairstyles such as high ponytails, it is difficult to wear and remove VR glasses with an integrated bandage, resulting in poor user experience; for VR glasses with a Velcro headband, the user needs to tighten the headband first after wearing and then bond the male and female stickers together. Since the user needs to bond the stickers in a reverse hand motion, the stickers are likely to be misaligned. The user may need to repeatedly tear and adjust the position, resulting in low wearing efficiency. Moreover, the adhesiveness of the stickers will gradually decrease with use and needs to be replaced on average every 3-6 months. Otherwise, there is a problem of falling off during wearing, posing a certain safety hazard. Therefore, improvement is needed. Summary of the Invention

[0004] In order to improve the wearing efficiency and removal efficiency of VR headset devices and reduce the occurrence of accidental detachment of VR headset devices, this application provides a magnetically-attached and quickly-detachable VR headset device.

Magnetic adsorption units are provided at both the left and right ends of the headset main body. A connection unit is magnetically adsorbed on the magnetic adsorption unit. The connection unit is connected to a sliding unit through an elastic unit. The same set of headband units is provided on the two sliding units. The headband units and the headset main body together enclose a wearing cavity; when the connection unit is magnetically adsorbed by the magnetic adsorption unit, the magnetic adsorption unit will simultaneously magnetically adsorb the sliding unit, causing the elastic unit to deform and reducing the horizontal distance between the headband units and the headset main body. The magnetic adsorption unit includes a mounting seat provided on the headset main body. A first slot is provided on the mounting seat, and a first magnetic block is provided in the first slot; the connection unit includes a connection seat for docking with the mounting seat. An installation groove corresponding to the first slot is provided on the connection seat. A plug is connected in the installation groove through a first spring. The plug is slidably embedded in the installation groove; when the connection seat is docked with the mounting seat, the first magnetic block will magnetically adsorb one end of the plug into the first slot, and the first spring will deform. The sliding unit includes a card seat, and a slider is provided on the card seat; the elastic unit includes a guide rail provided on the mounting seat, the slider is slidably engaged with the guide rail, and the slider is connected to the guide rail through a second spring, and the length direction of the second spring is the same as the length direction of the guide rail; a second slot is provided on the mounting seat, and a second magnetic block is provided in the second slot; when the connecting seat is docked with the mounting seat, the second magnetic block will magnetically adsorb one end of the card seat into the second slot, and the second spring will be deformed.

[0006] Optionally, a plurality of card slots are arranged in sequence along the length direction of the guide rail on the card seat; a clamping plate is rotatably connected to the mounting seat, and the clamping plate and the mounting seat are commonly connected with the same first torsion spring; when the first torsion spring is in a natural state, the clamping plate will be clamped in one of the card slots, and at this time the card seat can only move closer to the head-mounted display body. When the card seat moves closer to the head-mounted display body, it will push the clamping plate to rotate out of the card slot, and the first torsion spring will gradually return to the natural state and make the clamping plate be clamped in the next card slot.

[0007] Optionally, a rotation cavity for the clamping plate to rotate is provided on the side of the mounting seat, the rotation cavity communicates with the mounting groove, and one end of the clamping plate extends into the mounting groove; when the connecting seat slides out of the mounting seat, the first spring will return to the natural state and urge the insertion block to move back to its original position, and the insertion block will push the end of the clamping plate extending into the mounting groove to rotate, so that the clamping plate is separated from the movement track of the card seat.

[0008] Optionally, the headband unit includes a silica gel layer provided on two card seats, the silica gel layer is arranged in an arc shape, and a memory foam layer is provided on the inner side of the silica gel layer.

[0009] Optionally, a storage groove is provided on the upper surface of the silica gel layer, and a hoop belt that can be flipped in the vertical plane is rotatably connected in the storage groove, and the hoop belt has two states: use and storage; When the hoop belt is in the storage state, the hoop belt will be completely embedded in the storage groove; When the hoop belt is in the use state, the hoop belt will rotate to the upper oblique side of the wearing cavity, and the rotation angle of the hoop belt is less than 45 degrees.

[0010] Optionally, the hoop belt is rotatably connected to the silica gel layer through a rotating shaft, a reel is provided on the rotating shaft, the reel is connected to the mounting seat through a pull rope, and the reel and the silica gel layer are commonly connected with the same second torsion spring; During the process that the connecting seat is docked with the mounting seat and the second magnetic block gradually magnetically adsorbs one end of the card seat into the second slot, the pull rope will gradually become slack, and the second torsion spring will return to the natural state and urge the hoop belt to rotate to the use state.

[0011] Optionally, the mounting seat and the silica gel layer are commonly connected with the same woven bag, and the pull rope, the reel, the rotating shaft and the second torsion spring are all located inside the woven bag.

[0012] In summary, this application has the following beneficial technical effects: 1. During the wearing process of the VR head display device, the worker presses the head display body on the user's forehead with one hand and aligns the eyes with the view frame of the head display body. The worker holds the headband unit with one hand and moves the headband unit from back to front, so that the connecting base moves to the periphery of the mounting base. The magnetic unit will magnetically fix the connecting unit and the sliding unit, so that the headband unit is automatically tightened on the user's head, thereby realizing the rapid wearing of the VR head display device. This application adopts magnetic connection and fixation, and the magnetic force attenuation is less than 5%, which has a long service life and does not need to be replaced in a short time. It is also not easy to fall off when worn; 2. When the connection base and the mounting base are docked and the second magnetic block magnetically attracts the card base, the card base will move closer to the head display body. At this time, the card base will push the card plate to rotate out of the corresponding card slot, and the first torsion spring will deform. When the card plate corresponds to the next card slot, the first torsion spring will return to its natural state and force the card plate to be engaged in the card slot, that is, the card base can achieve multi-level adjustment. In addition, the cooperation between the card plate and the card slot prevents the card base from moving away from the head display body. That is, when the VR head display device is worn, as long as the connection base and the mounting base remain docked, the headband unit will not move away from the head display body. Therefore, even if the user is in motion, the VR head display body is not easily thrown off. 3. After the user wears the VR headset, the connecting base will be docked with the mounting base, and the second magnetic block will gradually magnetically attract one end of the card holder to the second slot. The card holder will gradually approach the headset body, the pull rope will gradually relax, and the second torsion spring will return to its natural state and prompt the strap to rotate upward to the upper part of the wearing cavity. At this time, the strap will be in use and tilted downward to press tightly against the back of the user's head. Since the overall weight of the VR headset is mainly concentrated on the headset body, the headset body has a tendency to fall. The setting of the strap can minimize the situation of the headset body falling. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0022] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 8 drawings.

[0023] The embodiment of the present application discloses a magnetic fast-release VR head-mounted display device. As Figure 1 shown, the magnetic fast-release VR head-mounted display device includes a head-mounted display main body 1. Magnetic attraction units 2 are provided at both the left and right ends of the head-mounted display main body 1. A connection unit 3 is magnetically adsorbed on the magnetic attraction unit 2. The connection unit 3 is connected to a sliding unit 5 through an elastic unit 4. The same set of headband units 6 are provided on the two sliding units 5. The headband unit 6 and the head-mounted display main body 1 together enclose a wearing cavity 61 for a user's head to be inserted into to complete the wearing of the VR head-mounted display device.

[0024] As Figure 2 shown, the magnetic attraction unit 2 includes a mounting seat 21. The mounting seat 21 is integrally formed with the outer shell of the head-mounted display main body 1 to ensure structural strength; a first slot 22 is provided on the mounting seat 21, and a first magnetic block 23 is fixedly embedded in the first slot 22.

[0025] As Figure 2 and Figure 3As shown, the connecting unit 3 includes a connecting seat 31, a mounting groove 32 is provided on the connecting seat 31, an insert block 34 is connected to the mounting groove 32 through a first spring 33, the insert block 34 is slidably embedded in the mounting groove 32, one end of the first spring 33 is fixedly connected to the connecting seat 31, and the other end of the first spring 33 is fixedly connected to the insert block 34.

[0026] During the wearing process of the VR head display device, the worker presses the head display body 1 on the user's forehead with one hand and aligns the eyes with the viewing frame of the head display body 1. The worker holds the headband unit 6 with one hand and moves the headband unit 6 from back to front, so that the connecting seat 31 moves to the periphery of the mounting seat 21; because the first magnetic block 23 can generate magnetic attraction on the plug-in block 34, the first magnetic block 23 and the plug-in block 34 cooperate with each other, so that the connecting seat 31 can quickly dock with the mounting seat 21, and make the mounting groove 32 correspond to the first slot 22, and then the first magnetic block 23 will magnetically fix the plug-in block 34, and one end of the plug-in block 34 will be inserted into the first slot 22. At this time, the first spring 33 will be deformed, and the user has completed the quick wearing of the VR head display device.

[0027] Compared with VR glasses with one-piece bandages, this application adopts a split design, so even if the user has a head shape such as a high ponytail, the user can quickly put on and take off the VR headset. After testing, the user only needs 2 seconds to put on the VR headset.

[0028] Compared with VR glasses with Velcro headbands, this application uses magnetic connection and fixation. The first magnetic block 23 can be made of neodymium iron boron magnet (N52 grade) material, which can withstand more than 100,000 times of disassembly and assembly, with magnetic attenuation of <5%. It has a long service life and does not need to be replaced in a short time. It is not easy to fall off when worn.

[0029] It is worth noting that both the insert block 34 and the first slot 22 are designed in a “convex” shape, and the convex end of the insert block 34 faces the wearing cavity 61 to improve the docking stability of the connecting seat 31 and the mounting seat 21.

[0030] like Figures 4 to 6 As shown, the sliding unit 5 includes a base 51, which is located on the side of the connecting base 31 facing the wearing cavity 61, and sliders 52 are integrally formed on both sides of the base 51; the elastic unit 4 includes two sets of guide rails 41 installed on the mounting base 21, and the sliders 52 slide in conjunction with the guide rails 41, so that the base 51 can only slide on the mounting base 21; in addition, the guide rails 41 adopt silent guide rails 41 to reduce the noise generated by the base 51 during the sliding process.

[0031] The slider 52 is connected to the guide rail 41 by a second spring 42. The length direction of the second spring 42 is the same as that of the guide rail 41. One end of the second spring 42 is fixedly connected to the slider 52, and the other end of the second spring 42 is fixedly connected to the guide rail 41. The arrangement of the second spring 42 enables the card holder 51 to remain stable without manual force application.

[0032] A second slot 24 is provided on the mounting base 21, and a second magnetic block 25 is fixedly embedded in the second slot 24. The length direction of the guide rail 41 is the same as that of the second slot 24. When the connecting seat 31 is docked with the mounting base 21, the card holder 51 will correspond to the second slot 24. At this time, the second magnetic block 25 will generate a magnetic attraction force on the card holder 51, and the card holder 51 will tend to move closer to the second magnetic block 25. The second spring 42 will deform, and the horizontal distance between the headband unit 6 and the head-mounted display main body 1 will decrease, enabling the VR head-mounted display device to automatically tighten on the user's head without the user manually adjusting the tightness of the VR head-mounted display device; in addition, the second magnetic block 25 will magnetically adsorb one end of the card holder 51 into the second slot 24, making it difficult for the headband unit 6 to shake relative to the head-mounted display main body 1, thereby improving the stability of the VR head-mounted display device during wearing.

[0033] It should be noted that the second magnetic block 25 can be made of neodymium iron boron magnet (N52 grade) material. This material can withstand more than 100,000 disassembly and assembly operations, with a magnetic force attenuation of <5%, a long service life, no need to be replaced in a short time, and it is not easy to fall off during wearing.

[0034] As Figure 6 and Figure 7 shown, a plurality of card slots 53 are arranged in sequence along the length direction of the guide rail 41 on the card holder 51. The card slots 53 are in the shape of a cuboid; a rotating cavity 35 is provided on the side of the mounting base 21. The rotating cavity 35 communicates with the mounting groove 32. A clamping plate 36 is provided in the rotating cavity 35. The middle part of the clamping plate 36 is rotatably connected to the cavity wall of the rotating cavity 35. One end of the clamping plate 36 extends to the card holder 51, and the other end of the clamping plate 36 extends into the mounting groove 32; the clamping plate 36 and the mounting base 21 are commonly connected with the same first torsion spring 37. One end of the first torsion spring 37 is fixedly connected to the clamping plate 36, and the other end of the first torsion spring 37 is fixedly connected to the mounting base 21.

[0035] Before the user wears the VR head-mounted display device, the first torsion spring 37 will be in a natural state, and the clamping plate 36 will be clamped in one of the card slots 53. The clamping plate 36 and the second spring 42 cooperate with each other to keep the card holder 51 stable relative to the connecting seat 31.

[0036] When the connection base 31 is docked with the mounting base 21 and the second magnetic block 25 magnetically attracts the card base 51, the card base 51 will move closer to the head display body 1. At this time, the card base 51 will push the card plate 36 to rotate and disengage from the corresponding card slot 53, and the first torsion spring 37 will be deformed; when the card plate 36 corresponds to the next card slot 53, the first torsion spring 37 will return to its natural state and prompt the card plate 36 to be clamped in the card slot 53, that is, the card base 51 can achieve multi-level adjustment; in addition, the cooperation between the card plate 36 and the card slot 53 prevents the card base 51 from moving away from the head display body 1, that is, during the wearing process of the VR head display device, as long as the connection base 31 and the mounting base 21 remain docked, the headband unit 6 will not be able to move away from the head display body 1, so even if the user is in motion, the VR head display body 1 is not easily thrown off.

[0037] When the user needs to remove the VR head display device, the user presses the head display body 1 with one hand and pulls the headband unit 6 backward with the other hand to separate the connecting seat 31 from the mounting seat 21. At this time, the VR head display device can be quickly removed.

[0038] like Figure 4 As shown, it is worth noting that when the connecting seat 31 slides out of the mounting seat 21, the first spring 33 will return to its natural state and prompt the plug block 34 to move and reset. The plug block 34 will penetrate into the mounting groove 32 and push the end of the card plate 36 that extends into the mounting groove 32 to rotate. The other end of the card plate 36 will rotate out of the motion trajectory of the card seat 51. At this time, the card plate 36 will no longer clamp the card seat 51. The second spring 42 will return to its natural state and prompt the card seat 51 and the headband unit 6 to move and reset, so that the VR head display device can be worn in the subsequent process.

[0039] like Figure 4 and Figure 8 As shown, the headband unit 6 includes an arc-shaped silicone layer 62, one end of the silicone layer 62 is installed on one of the holders 51, and the other end of the silicone layer 62 is installed on the other holder 51. A memory foam layer 63 is bonded to the inner side of the silicone layer 62, and the silicone layer 62 is used to support the memory foam layer 63. The memory foam layer 63 is used to resist the back of the user's head and the side of the forehead to improve the user's comfort when wearing it.

[0040] An arc-shaped receiving groove 64 is provided on the upper surface of the silicone layer 62, and a hoop 66 that can be flipped on a vertical plane is rotatably connected to the groove wall of the receiving groove 64 through a rotating shaft 65. The hoop 66 is made of elastic material, preferably silicone; a reel 67 is fixedly sleeved on the rotating shaft 65, and the surface of the reel 67 is connected to the mounting seat 21 through a pull rope 69, and the reel 67 and the silicone layer 62 are commonly connected to the same second torsion spring 68, one end of the second torsion spring 68 is fixedly connected to the reel 67, and the other end of the second torsion spring 68 is fixedly connected to the silicone layer 62.

[0041] Before the user wears the VR head display device, the pull rope 69 will be in a taut state, the second torsion spring 68 will be in a deformed state, and the strap 66 will be completely embedded in the storage groove 64. At this time, the strap 66 will be in a storage form to facilitate the overall storage of the VR head display device.

[0042] After the user wears the VR head display device, the connecting seat 31 will be docked with the mounting seat 21, and the second magnetic block 25 will gradually magnetically attract one end of the card holder 51 to the second slot 24. The card holder 51 will gradually approach the head display body 1, the pull rope 69 will gradually relax, and the second torsion spring 68 will return to its natural state and prompt the strap 66 to rotate upward to the upper side of the wearing cavity 61. The rotation angle of the strap 66 is less than 45 degrees, preferably 30 degrees, so that the user's high ponytail is not likely to affect the upward flipping of the strap 66. At this time, the strap 66 will be in use and tilted downward to press tightly against the back of the user's head; since the overall weight of the VR head display device is mainly concentrated on the head display body 1, the head display body 1 has a tendency to fall. The setting of the strap 66 can avoid the head display body 1 from falling as much as possible.

[0043] The mounting base 21 and the silicone layer 62 are connected to the same woven bag 7. The pull rope 69, the reel 67, the rotating shaft 65 and the second torsion spring 68 are all located inside the woven bag 7. The woven bag 7 is relatively wear-resistant and can accommodate the pull rope 69, the reel 67, the rotating shaft 65 and the second torsion spring 68, thereby avoiding exposure of parts as much as possible.

[0044] The implementation principle of the magnetic quick-release VR head display device of the embodiment of the present application is as follows: during the wearing process of the VR head display device, the worker presses the head display body 1 on the user's forehead with one hand and aligns the eyes with the view frame of the head display body 1. The worker holds the headband unit 6 with one hand and moves the headband unit 6 from back to front, so that the connecting seat 31 moves to the periphery of the mounting seat 21; the first magnetic block 23 will generate a magnetic attraction force on the insertion block 34, so that the connecting seat 31 quickly docks with the mounting seat 21, the first magnetic block 23 will magnetically fix the insertion block 34 in the first slot 22, and the second magnetic block 25 will magnetically fix the clamping seat 51 in the second slot 24. The clamping seat 51 will drive the headband unit 6 close to the head display body 1, so that the VR head display device is automatically tightened on the user's head; in addition, the pull rope 69 will gradually relax, the second torsion spring 68 will return to its natural state and prompt the strap 66 to rotate upward to the oblique upper part of the wearing cavity 61. At this time, the strap 66 will be in use and tilted downward to press tightly against the back of the user's head.

[0045] To sum up, the user only needs to dock the connecting seat 31 with the mounting seat 21 to automatically tighten the VR head display device on the user's head, thereby realizing the quick wearing of the VR head display device and being suitable for different head hairstyles of users; at the same time, the magnetic fixation of the first magnetic block 23 to the plug block 34, the magnetic fixation of the second magnetic block 25 to the card seat 51, the card fixation of the card seat 51 by the card plate 36, the multi-directional resistance and pressure of the head display body 1, the memory foam layer 63 and the strap 66 on the user's head will ensure the stability of the VR head display device during wearing, thereby reducing the occurrence of accidental detachment of the VR head display device; in addition, the user only needs to pull off the connecting seat 31 and the mounting seat 21 to remove the VR head display device, thereby realizing the quick removal of the VR head display device.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
