Description

Technical Field

[0001] The invention belongs to the technical field of virtual reality, in particular to a pair of VR glasses. Background Art

[0002] VR glasses are head-mounted devices specifically used to experience virtual reality content. This device creates an immersive virtual environment through audio-visual technology, allowing users to interact with the virtual world. Through a computer-generated three-dimensional environment, users can interact with the environment through specific devices.

[0003] A Chinese patent application CN114624884B discloses a VR glasses, including a glasses body, a head-mounted assembly and an anti-collision assembly. The glasses body is used by users to realize virtual projects. The head-mounted assembly connects the glasses body and the anti-collision assembly. The anti-collision assembly includes a connected trigger module and an airbag module. The airbag module includes a safety airbag, and the trigger module can cause the safety airbag to inflate. In the above manner, when the user uses the VR glasses, the trigger module detects the user's body posture state. When it is detected that the user's body is tilted and falling, the safety airbag is caused to inflate, so that the airbag plays a protective role for the user.

[0004] Although the above technology binds the glasses body to the user's head through multiple air bags, the user's eyes are completely covered when in use. At this time, the hearing and vision are interacting with the VR glasses, and the sense of smell is still interacting with the external real environment, which causes olfactory information deviation and affects the interaction experience.

DETAILED DESCRIPTION

[0052] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0053] like Figures 1 to 10 As shown, the VR glasses described in the present invention include a body shell, a heat dissipation mechanism, a liquid supply mechanism, a bearing mechanism and a control mechanism.

[0054] The body shell includes a glasses shell 1 and a mounting shell 3. The glasses shell 1 has a built-in virtual reality module and is worn by a user. A strap is arranged outside the glasses shell 1 for binding with the user's head. The virtual reality module is composed of a display screen, an optical lens, a sensor, an audio system, a processor, a storage unit, a power supply unit, a connection interface and a processor (the internal electronic components of the virtual reality module VR glasses are prior art and will not be described in detail here). The mounting shell 3 is arranged at the bottom of the glasses shell 1. A cavity is arranged inside the mounting shell 3, and a through hole for exhaust is opened on the outside.

[0055] The heat dissipation mechanism includes a control fan 9, a heat conducting plate 8 and a heat exchange plate 11. The heat exchange plate 11 is fixedly installed above the mounting shell 3, and one end is connected to the heat conducting plate 8. The heat conducting plate 8 and the heat exchange plate 11 are evenly connected to each other. There are multiple heat exchange plates 11 arranged at equal distances and parallel to each other.

[0056] One side of the heat conducting plate 8 is in contact with the heating end of the processor of the virtual reality module. Silicone grease is evenly coated on the contact position between the heat conducting plate 8 and the heating end of the processor. The fan 9 is controlled to be fixedly installed on the outer wall of the heat exchange plate 11. By controlling the fan 9 to blow air toward the gaps between the multiple heat exchange plates 11, the air flow speed on the outer wall of the heat exchange plate 11 is increased, thereby improving the heat dissipation efficiency of the processor.

[0057] The bearing mechanism includes a winding roller 10, an absorption sheet 7 and a control panel 6. The winding roller 10 is used to wind up the absorption sheet 7 and is rotatably mounted on the inner wall of the mounting shell 3 through a torsion spring. The absorption sheet 7 is a non-woven fabric. After rotating the winding roller 10, the elastic force of the torsion spring is used to control the winding roller 10 to reset.

[0058] The control board 6 is disposed outside the mounting shell 3 and connected to the other end of the absorption sheet 7 . Pulling the control board 6 drives the absorption sheet 7 to extend to the outside of the mounting shell 3 .

[0059] The liquid supply mechanism is used to store the volatile liquid, and the control mechanism is used to control the volatile liquid to be applied to the outer wall of the absorption sheet 7. In this embodiment, the volatile liquid is an aromatherapy liquid with a volatilization effect. After being immersed in the absorption sheet 7, the absorption sheet 7 is pulled out of the outer wall of the mounting shell 3 to emit fragrance. When using VR glasses, the fragrance is emitted in conjunction with the video content being played to enhance the experience.

[0060] The control fan 9 is fixedly installed on the outer wall of the heat exchange plate 11 and blows air toward the absorption plate 7. After the heat generated by the processor is absorbed by the heat exchange plate 11, it is blown out by the control fan 9. On the one hand, the air flow improves the volatilization efficiency of the aroma in the absorption plate 7, and at the same time, the useless heat energy generated by the processor is utilized to further improve the volatilization efficiency of the aroma. With the cooperation of each other, when the user experiences the visual and auditory virtual reality, the olfactory stimulation is simultaneously emitted, thereby improving the user experience.

[0061] As a preferred embodiment of the present invention, a connecting rod 5 is slidably installed in the mounting shell 3, one end of the connecting rod 5 extends to the outer wall of the mounting shell 3 and is fixedly connected to the outer wall of the control panel 6. The sliding connection between the control panel 6 and the mounting shell 3 is realized through the connecting rod 5, which is used to provide support for the control panel 6.

[0062] A locking rod 12 is elastically installed on the outer wall of the connecting rod 5, and a locking groove 2 for the locking rod 12 to be inserted into the outer wall of the mounting shell 3. In the process of pulling the connecting rod 5 out of the mounting shell 3, the locking rod 12 gradually pops out until one end of the locking rod 12 is aligned with the locking groove 2. At this time, the connecting rod 5 is released and the elastic force of the torsion spring on the winding roller 10 is used. The winding absorption sheet 7 pulls the connecting rod 5 to reset. At this time, the locking rod 12 is inserted into the locking groove 2 to fix the control panel 6 and keep a part of the absorption sheet 7 outside the mounting shell 3 to facilitate the release of fragrance.

[0063] After the experience is over, the locking rod 12 is pressed until the locking rod 12 is retracted into the interior of the connecting rod 5 , at which time the control plate 6 is reset by the elastic force of the torsion spring, and the absorption sheet 7 is stored.

[0064] As a preferred embodiment of the present invention, the control mechanism includes a smear roller 15, a liquid guide plate 16 and a mounting frame 13, wherein the mounting frame 13 is fixedly mounted on the inner wall of the mounting shell 3, and the smear roller 15 is rotatably mounted on the side wall of the mounting frame 13, wherein two mounting frames 13 are provided, symmetrically arranged on both sides of the smear roller 15, and a sponge is provided on the outside of the smear roller 15.

[0065] The liquid guide plate 16 is spiral and fixedly mounted on the radial outer wall of the outer wall of the smear roller 15. The outer wall of the liquid guide plate 16 is slidably fitted with the outer wall of the absorption sheet 7. The absorption sheet 7 is tensioned by fitting with the liquid guide plate 16. In the process of pulling out the absorption sheet 7, the volatile liquid is applied to the sponge outside the smear roller 15. After the sponge absorbs the volatile liquid, it is immersed in the absorption sheet 7, so that the absorption sheet 7 absorbs the volatile liquid.

[0066] The smear roller 15 is connected to the winding roller 10 through a transmission member, and the transmission member is a common belt and pulley. The smear roller 15 is driven to rotate during the rotation of the winding roller 10, so as to prevent the smear roller 15 from contacting the absorbent sheet 7 at the same position during the pulling out of the absorbent sheet 7, so as to facilitate uniform smearing.

[0067] The liquid supply mechanism includes a storage tank 4, a connecting pipe 14 and a support plate 17. The storage tank 4 is fixedly installed in the installation shell 3. The storage tank 4 is used to store volatile liquid. An L-shaped tube is arranged on the outside thereof for replenishing the volatile liquid. At the same time, when the volatile liquid in the storage tank 4 flows out, the external air penetrates into the inner cavity of the storage tank 4 through the L-shaped tube to maintain the air pressure balance in the inner cavity of the storage tank 4.

[0068] One end of the connecting tube 14 is fixedly connected to the outer wall of the storage tank 4, and the other end of the connecting tube 14 is fixedly connected to the outer wall of the support plate 17. The inner cavity of the storage tank 4 is connected to the inner cavity of the support plate 17 through the connecting tube 14, and the volatile liquid in the inner cavity of the storage tank 4 flows into the interior of the support plate 17 through the connecting tube 14.

[0069] The outer wall of the support plate 17 is slidably fitted with the outer wall of the liquid guide plate 16. When the smear roller 15 rotates, the volatile liquid inside the support plate 17 is scraped by the spiral liquid guide plate 16 and transported to the sponge outside the smear roller 15 as much as possible.

[0070] A connecting plate 23 is slidably installed on the inner wall of the mounting frame 13, and a plurality of support plates 17 are evenly arranged along the outer wall of the coating roller 15. The plurality of support plates 17 are connected by the connecting plates 23. Increasing the number of support plates 17 can increase the position for replenishing volatile liquid to the outside of the coating roller 15, and keep the volatile liquid on the outside of the coating roller 15 as uniform as possible, so as to facilitate uniform immersion of the volatile liquid on the outside of the absorption sheet 7.

[0071] The inner wall of the support plate 17 is provided with an absorption layer 37 . The absorption layer 37 is made of elastic material and is in contact with the liquid guide plate 16 . The absorption layer 37 is a common sponge. By arranging the absorption layer 37 to absorb the volatile liquid, the speed at which the volatile liquid flows out of the support plate 17 is slowed down, thereby preventing the volatile liquid from flowing out directly from the support plate 17 .

[0072] When the smear roller 15 rotates, the liquid guide plate 16 rotates, thereby uniformly squeezing the outside of the absorption layer 37 , squeezing out the volatile liquid in the absorption layer 37 , and scraping it off by the liquid guide plate 16 for absorption by the smear roller 15 .

[0073] As a preferred embodiment of the present invention, one end of the connecting tube 14 connected to the storage tank 4 is an elastic tube, which is an elastic rubber tube, and one end of the connecting tube 14 connected to the support plate 17 is a hard tube, which is a hard copper tube.

[0074] An upper limit plate 18 and a lower limit plate 21 are fixedly installed on the inner wall of the connecting pipe 14. Conical holes are formed in the upper limit plate 18 and the lower limit plate 21. The chamber between the upper limit plate 18 and the lower limit plate 21 is filled with an elastic layer for absorbing volatile liquid. The elastic layer is made of common sponge.

[0075] When the lower limit plate 21 is blocked, the elastic layer is connected to the upper part of the connecting pipe 14, thereby absorbing the volatile liquid left by the storage tank 4 at the upper part, and then the upper limit plate 18 is blocked. At the same time, the lower limit plate 21 is controlled to be conductive, squeezing the elastic layer. The volatile liquid absorbed in the elastic layer is left along the through hole of the lower limit plate 21 and absorbed by the absorption layer 37 in the support plate 17.

[0076] A transmission rod 22 is slidably mounted on the inner wall of the support plate 17, wherein the outer portion of the transmission rod 22 is bonded to the absorption layer 37. When the smear roller 15 rotates, the transmission rod 22 is pressed by the liquid guide plate 16. After the transmission rod 22 and the liquid guide plate 16 are separated, the transmission rod 22 is reset by controlling the elasticity of the absorption layer 37 to facilitate the next pressing.

[0077] The bottom of the transmission rod 22 is a spherical structure to prevent the transmission rod 22 from interfering with the rotation of the liquid guide plate 16 .

[0078] The outer wall of the transmission rod 22 passes through the lower limit plate 21 and is fixedly installed with a lower sealing plug 20 for sealing the lower limit plate 21. The sliding transmission rod 22 drives the lower sealing plug 20 to move, so that the lower sealing plug 20 can seal the lower limit plate 21, and at the same time it is convenient to control the separation of the lower sealing plug 20 from the lower limit plate 21.

[0079] An upper sealing plug 19 for sealing the upper limit plate 18 is elastically mounted on one end of the transmission rod 22 , and the transmission rod 22 is elastically connected to the upper sealing plug 19 via an elastic rubber block.

[0080] When the liquid guiding plate 16 presses the transmission rod 22, the lower sealing plug 20 squeezes the elastic layer and seals the upper limit plate 18 through the upper sealing plug 19. When the liquid guiding plate 16 is separated from the transmission rod 22 and the transmission rod 22 slides down, the lower sealing plug 20 seals the lower limit plate 21. At this time, the upper limit plate 18 is turned on and the elastic layer absorbs the volatile liquid.

[0081] When squeezing the elastic layer, blocking the upper limit plate 18 can prevent the volatile liquid in the elastic layer from flowing back upward along the connecting pipe 14. When the elastic layer absorbs the volatile liquid, the lower limit plate 21 is blocked to prevent the elastic layer from absorbing the volatile liquid in the absorption layer 37 below, thereby maintaining the stability of the liquid supply.

[0082] As a preferred embodiment of the present invention, a control frame 25 is slidably installed on the outer wall of the mounting frame 13. The control frame 25 is a U-shaped frame. The upper end of the control frame 25 is fixedly connected to the bottom surface of the connecting plate 23. A transmission bevel block 26 is fixedly installed on the inner wall of the control frame 25. The sliding control frame 25 controls the synchronous sliding of the connecting plate 23.

[0083] When the absorbent sheet 7 is pulled out, the sliding control frame 25 controls the support plate 17 to fit with the liquid guide plate 16 through the connecting plate 23, thereby facilitating the application of the volatile liquid. When the absorbent sheet 7 is stored, the sliding control frame 25 separates the support plate 17 from the liquid guide plate 16, thereby interrupting the liquid supply to the application roller 15 and reducing the useless consumption of the volatile liquid.

[0084] A transmission ring 29 is rotatably mounted on the side wall of the mounting frame 13. A pressing rod 27 for pressing the transmission bevel block 26 is fixed to the outer wall of the transmission ring 29. Rotating the transmission ring 29 drives the pressing rod 27 to rotate, wherein the pressing rod 27 is an elastic plate.

[0085] There are two transmission bevel blocks 26, which are respectively located on the upper and lower sides of the control frame 25. The two transmission bevel blocks 26 are staggered. The number of transmission rings 29 is consistent with the number of transmission bevel blocks 26, and the positions correspond. When the absorption sheet 7 is pulled out, one of the transmission rings 29 rotates. At this time, the pressing rod 27 outside the transmission ring 29 presses the transmission bevel block 26 located below, so that the control frame 25 slides downward until the support plate 17 is in contact with the liquid guide plate 16.

[0086] When the absorbent sheet 7 is rolled up, another transmission ring 29 is rotated, and the pressing rod 27 outside the transmission ring 29 presses the upper transmission inclined block 26, thereby lifting the control frame 25 and controlling the support plate 17 and the liquid guide plate 16 to separate.

[0087] A transmission shaft 28 is fixedly mounted on the axial end of the smear roller 15. When the smear roller 15 rotates, the transmission shaft 28 rotates synchronously. When the absorbent sheet 7 is pulled out, the transmission shaft 28 rotates forward, and when the absorbent sheet 7 is rolled up, the transmission shaft 28 rotates reversely.

[0088] An adjusting bevel block 31 is fixedly installed on the inner wall of the transmission ring 29, and an elastic bevel plate 32 for pressing the adjusting bevel block 31 is fixedly installed on the outer wall of the transmission shaft 28. The inclination direction of the adjusting bevel block 31 in one transmission ring 29 is opposite to the inclination direction of the adjusting bevel block 31 in the other transmission ring 29. The elastic bevel plate 32 is tilted to limit the rotation direction of the transmission ring 29. When the transmission shaft 28 rotates forward, the two elastic bevel plates 32 both rotate, and the adjusting bevel block 31 corresponding to the elastic bevel plate 32 is driven to engage through one of the elastic bevel plates 32. At this time, the elastic bevel plate 32 pushes the transmission ring 29 outside the adjusting bevel block 31 to rotate through the adjusting bevel block 31, thereby driving the control frame 25 to descend.

[0089] When the transmission shaft 28 rotates in the opposite direction, another elastic inclined plate 32 engages with another adjusting inclined block 31 , thereby driving another transmission ring 29 to rotate, and at this time, the control frame 25 is lifted to facilitate the separation of the liquid guide plate 16 and the support plate 17 .

[0090] As a preferred embodiment of the invention, a mounting block 24 is fixedly installed on the side wall of the mounting frame 13, and a limit pin 33 is elastically fixedly installed on the mounting block 24. One end of the limit pin 33 is spherical, and a spherical groove 30 for the limit pin 33 to be inserted is opened on the side wall of the control frame 25. The limit pin 33 is connected to the mounting block 24 through a spring, and the limit pin 33 is pushed by the elastic force of the spring, so that the limit pin 33 has a real-time tendency to extend outward.

[0091] There are two spherical grooves 30, and the distance between the two spherical grooves 30 is adapted to the height of the transmission bevel block 26. After the control frame 25 is slid downward, the limit pin 33 is plugged into the spherical groove 30 located above to keep the position of the control frame 25 fixed, thereby keeping the support plate 17 and the liquid guide plate 16 in a fitted state.

[0092] After the control frame 25 slides upward, the limiting pin 33 is plugged into the spherical groove 30 located below to keep the control frame 25 fixed, thereby keeping the support plate 17 and the liquid guide plate 16 in a separated state.

[0093] A plug-in plate 36 is elastically mounted on the inner wall of the mounting block 24, a connecting block 35 is fixedly mounted on the outer wall of the plug-in plate 36, the connecting block 35 is connected to the mounting block 24 via a spring, a friction plate 34 for pressing the transmission ring 29 is fixedly mounted on the other end of the connecting block 35, and the friction plate 34 is a rubber plate.

[0094] Among them, when one group of adjusting bevel blocks 31 and elastic bevel plates 32 rotate, another group of adjusting bevel blocks 31 and elastic bevel plates 32 slip. In order to prevent the sliding friction between the elastic bevel plates 32 and the adjusting bevel blocks 31 from causing the transmission ring 29 to rotate, the friction plate 34 is pushed to fit the radial outer wall of the transmission ring 29 through the connecting block 35, thereby increasing the resistance to the rotation of the transmission ring 29, preventing the sliding friction between the elastic bevel plates 32 and the adjusting bevel blocks 31 from causing the transmission ring 29 to rotate, and improving the stability of the control frame 25 lifting and lowering.
