VR headsets use head-mounted display devices to block people's vision and hearing from the outside world, guiding users to feel like they are in a virtual environment. The display principle is that the left and right eye screens display the left and right eye images respectively, and the human eye obtains this different information and creates a three-dimensional sense in the mind.

[0016] The present invention has the following beneficial effects: 1. In the VR glasses, the mobile phone is limited and fixed by the edge of the positioning box. When the positioning box moves toward the position of the mobile phone, the power storage component stores power. After the power storage component stores power, the restriction on the power storage component is released by the restriction release component, so that the power storage component releases power, drives the transmission rack to move, and the movement of the transmission rack drives the guide block to move. The guide block conflicts with the first resistance block, so that the first resistance block slides along the lower surface of the guide block, so that the first resistance block drives the pressing block to move, so that the pressing block moves a distance toward the mobile phone, thereby completing the pressing of the mobile phone. The stability of the mobile phone in the placement slot is increased to prevent the mobile phone from shaking, and a heat conductive sheet is arranged on the inner side of the positioning box. When the mobile phone is pressed and fixed, the pressing roller is driven to move through the transmission gear, so that the pressing roller moves along the heat conductive sheet and presses the heat conductive sheet onto the surface of the mobile phone. The good thermal conductivity of the heat conductive sheet is used to conduct the heat on the surface of the mobile phone, which is convenient for heat dissipation. Therefore, when the VR glasses are used, it is convenient to dissipate the heat of the mobile phone. The heat dissipation effect of the mobile phone is good, and the situation that the solid pressing plate is used to fix the mobile phone to affect the heat dissipation of the mobile phone is avoided. 2. In the VR glasses, when the pressing roller moves along the surface of the heat conducting sheet, the pressing roller drives the heat sink to move through the cross bar, the connecting plate and the first telescopic rod, and lays the heat sink flat on the heat conducting sheet. When the heat sink moves, the sliding bar is driven to slide in the track groove. When the heat sink is laid flat on the heat conducting sheet, the heat sink moves a distance in the direction of the heat conducting sheet, so that the heat sink is pressed against the heat conducting sheet. Therefore, the heat sink presses the heat conducting sheet against the surface of the mobile phone, thereby increasing the adhesion between the heat conducting sheet and the surface of the mobile phone, making it easier for the heat conducting sheet to conduct heat to the mobile phone, and facilitating the heat sink to absorb the heat transferred by the heat conducting sheet, and dissipating heat through the heat sink and the heat dissipation strip, thereby increasing the heat dissipation effect; 3. In the VR glasses, when the heat sink moves a certain distance in the direction of the heat conducting plate, it will drive the sliding rod to slide in the track groove, and will also drive the inner connecting rod to slide in the track groove. When the heat sink completes the pressing attachment to the heat conducting plate, the inner connecting rod abuts the second abutting block, so that the second abutting block drives the straight plate to move, and the movement of the straight plate drives the third abutting block to move, so that the third abutting block abuts the heat sink, and pushes the heat sink out of the heat conducting cavity. After the heat sink is pushed out of the heat conducting cavity, it is equivalent to extending the leakage length of the heat sink, which is convenient for increasing the heat dissipation effect. In addition, when the heat sink is reset, the straight plate, the second abutting block, and the inner connecting rod are reset, and the heat sink is pulled back into the heat conducting cavity, so as to facilitate the storage of the heat sink, which can increase the heat dissipation effect during heat dissipation. When the VR glasses are not in use, the space occupied by the heat sink is reduced, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

A sliding groove 171 is provided in the limiting column 17, and a sixth spring 172 is provided in the sliding groove 171. The two ends of the sixth spring 172 are respectively fixedly provided on the inner wall of the sliding groove 171 and the lifting rod 13. A first groove 18 is provided inside the positioning box 5, and the support rod 16 is slidably connected to the first groove 18. A first spring 19 is provided in the first groove 18, and the two ends of the first spring 19 are fixedly provided between the support rod 16 and the inner wall of the first groove 18; A cross bar 20 is fixed on the lifting rod 13, a lever 21 is fixed on the cross bar 20, the lever 21 penetrates the positioning box 5, and a slideway 22 for the lever 21 to slide is provided on the positioning box 5; In this technical solution, when using the VR glasses, firstly, the positioning box 5 needs to be opened, and the mobile phone 2 is placed in the placement slot 3 (such as Figure 1 ), after the mobile phone 2 is placed in the placement slot 3, the mobile phone 2 needs to be fixed. At this time, the positioning box 5 is pressed to move the positioning box 5 to the outside of the mobile phone 2 to limit the position of the mobile phone 2; When the positioning box 5 is pressed to move toward the mobile phone 2, the positioning box 5 slides relative to the connecting rod 4. During the sliding process of the positioning box 5, the driving rack 81 drives the first driving gear 82 to rotate. The rotation of the first driving gear 82 causes the torsion spring 85 to store force. When the positioning box 5 slides to press the mobile phone 2, the first driving gear 82 rotates to the end of the driving rack 81, and the first driving gear 82 is still meshed with the driving rack 81, so that the first driving gear 82 cannot continue to rotate. At the same time, the protrusion 121 contacts the convex strip 124, prompting the convex strip 124 to move. The movement of the convex strip 124 drives the limiting rod 123 to move. The limiting rod 123 moves to move the block 125 out from between the first spring piece 127 and the second spring piece 128, so that the block 125 moves to the top of the first spring piece 127 (such as Fig. 9 As shown), at this time, the limiting rod 123 no longer conflicts with the second driving gear 84, and the second driving gear 84 is released from the restriction. The torsion spring 85 releases the force. Since the first driving gear 82 cannot continue to rotate, the second driving gear 84 rotates in the opposite direction of the first driving gear 82. The rotation of the second driving gear 84 drives the transmission rack 9 to move, and the movement of the transmission rack 9 drives the guide block 10 to move. The guide block 10 conflicts with the first conflicting block 11, so that the first conflicting block 11 slides along the lower surface of the guide block 10, so that the first conflicting block 11 drives the pressing block 7 to move, and the pressing block 7 moves a distance toward the mobile phone 2, thereby completing the pressing process of the mobile phone 2, increasing the mobile phone 2 in the placement slot 3. The internal stability prevents the mobile phone 2 from shaking. The interior of the accommodating groove 6 is elastically connected to the pressing block 7 through the fifth spring 41 and the second telescopic rod 42. Both ends of the fifth spring 41 and the second telescopic rod 42 are fixed on the inner wall of the accommodating groove 6 and the surface of the pressing block 7, and the fifth spring 41 is sleeved on the circumference of the second telescopic rod 42. When the pressing block 7 moves a certain distance toward the mobile phone 2, the fifth spring 41 accumulates force, which is convenient for the subsequent resetting of the pressing block 7. By setting the second telescopic rod 42, when the first abutting block 11 is abutted by the guide block 10, the pressing block 7 can only move toward the mobile phone, and when the pressing block 7 is reset, it moves in the opposite direction, and no movement in other directions occurs; Since the sixth spring 172 is in a compressed state at the beginning, the sixth spring 172 accumulates force. When the pressing block 7 moves a certain distance toward the mobile phone 2, the heat conductive sheet 15 on one side is driven to move. At this time, the sixth spring 172 releases force and pushes the lifting rod 13 to move, so that the lifting rod 13 can drive the pressure roller 14 to move the same distance, so that the pressure roller 14 is always on the upper surface of the heat conductive sheet 15. The heat conductive sheet 15 is a silicone heat conductive sheet 15. When the transmission rack 9 moves, the lifting rod 13 is driven to move. The lifting rod 13 drives the pressure roller 14 to move, so that the pressure roller 14 presses the heat conductive sheet 15 to the surface of the mobile phone 2, and at the same time pulls the support rod 16 to slide in the first groove 18. The support rod 16 presses the first spring 19 to store force. The end of the support rod 16 is set to a T-shaped structure, and the first groove 18 is set to a T-shaped groove. When sliding in the first groove 18, it will not be pulled out, and the first spring 19 stores force to provide elastic force for the subsequent reset of the heat conductive sheet 15. When the lifting rod 13 drives the pressure roller 14 to move, it also drives the cross bar 20 to move. The movement of the cross bar 20 drives the lever 21 to slide in the slideway 22, and slides the lever 21 to the top of the slideway 22. In this solution, after the positioning box 5 fixes the mobile phone 2, the pressing block 7 can first be used to press and fix the mobile phone 2 to increase the stability of the mobile phone 2, and then the heat conductive sheet 15 is pressed and attached to the surface of the mobile phone 2 by the pressure roller 14, and the surface of the mobile phone 2 is heat-conducted by the heat conductive sheet 15, which is convenient for the heat of the mobile phone 2 to be discharged and the heat dissipation of the mobile phone 2 is convenient. The outer surface of the positioning box 5 is set to a mesh structure, which is conducive to heat dissipation and ventilation, and at the same time increases the pressure and adhesion, effectively avoiding the effect of air when the heat conductive sheet 15 and the surface of the mobile phone 2 are adhered, and the heat conduction effect is better; When the positioning box 5 is opened, the positioning box 5 slides relative to the connecting rod 4 in the direction away from the mobile phone 2. Since the second driving gear 84 is released from the restriction, the driving rack 81 drives the first driving gear 82 to reverse, and the second driving gear 84 tends to rotate in the same direction as the first driving gear 82, but the transmission rack 9 cannot continue to move forward. The second driving gear 84 meshes with the transmission rack 9, making it impossible for the second driving gear 84 to rotate. At this time, the torsion spring 85 accumulates force. After the positioning box 5 is fully opened, the driving rack 81 slides over the first driving gear 82 and loses meshing with the first driving gear 82. The torsion spring 85 releases its force, the first driving gear 82 is reset, and then reset by pushing the lever 21, the lever 21 drives the transmission rack 9 to reset, the transmission rack 9 is reset, so that the clamping block 7, the pressure roller 14, and the heat conducting sheet 15 are reset, and then the button 129 is pressed downward to drive the limiting rod 123 to move, the limiting rod 123 drives the card block 125 to move between the first spring piece 127 and the second spring piece 128 again, so that the limiting rod 123 limits the second driving gear 84 again, so that the entire structure is reset, and the VR glasses can be used next time.

[0035] Embodiment 2

[0036] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 14 ,: The cross bar 20 is also provided with a connecting plate 23, and the connecting plate 23 is movably connected to a heat sink 24 through a first telescopic rod 40, and the heat sink 24 is provided with a plurality of heat dissipation grooves 25, and a plurality of heat dissipation strips 26 are provided on both sides of the heat sink 24. A second spring 27 is sleeved on the first telescopic rod 40, and both ends of the second spring 27 are fixedly arranged on the connecting plate 23 and the heat sink 24. A slide bar 28 is fixed on the heat sink 24, and the slide bar 28 is arranged to penetrate the pressing block 7, and a track groove 29 for the slide bar 28 to slide is opened on the inner wall of the positioning box 5; The track groove 29 includes a vertical portion 291, a horizontal portion 292 and a descending portion 293 which are connected in sequence, and an inner wall of the descending portion 293 is further provided with an inclined portion 294; In the present technical solution, the heat sink 24 is slidably arranged on the inner side of the pressing block 7, and a notch 43 for the slide bar 28 to slide is provided on the outer side of the pressing block 7. The slide bar 28 is restricted by the notch 43, so that when the pressing block 7 presses the mobile phone 2, the pressing block 7 drives the slide bar 28 to move, the slide bar 28 drives the heat sink 24 to move, and the heat sink 24 drives the slide bar 28 to move along the vertical portion 291 of the track groove 29 and move to the connection between the vertical portion 291 and the horizontal portion 292 (such as Fig.13 As shown in the figure, in the process of the pressing roller 14 pressing the heat conductive sheet 15 onto the surface of the mobile phone 2, the pressing roller 14 drives the heat sink 24 to move through the cross bar 20, the connecting plate 23 and the first telescopic rod 40, so that the heat sink 24 moves along the horizontal portion 292 of the track groove 29 with the slide bar 28, thereby pulling out the heat sink 24 and laying the heat sink 24 flat on the surface of the heat conductive sheet 15; in order to better dissipate the heat of the heat conductive sheet 15 through the heat conductive sheet 24, and to increase the fit between the heat conductive sheet 15 and the surface of the mobile phone 2, and to further increase the heat conductivity of the heat conductive sheet 15 to the mobile phone 2, when the heat sink 24 moves down from the horizontal portion 292 of the track groove 29 with the slide bar 28, When the heat sink 24 moves toward the heat conducting sheet 15, the second spring 27 is stretched to store force, and the first telescopic rod 40 is extended to facilitate the subsequent resetting of the heat sink 24. Since the silicone heat conducting sheet 15 has a certain elasticity, the heat sink 24 will press the heat conducting sheet 15 against the surface of the mobile phone 2, thereby increasing the adhesion between the heat conducting sheet 15 and the surface of the mobile phone 2, making it easier for the heat conducting sheet 15 to conduct heat to the mobile phone 2, and making it easier for the heat sink 24 to absorb the heat transferred by the heat conducting sheet 15, and dissipate heat through the heat sink 24 and the heat dissipation strip 26, thereby increasing the heat dissipation effect.

[0037] Embodiment 3

[0038] Since the positions of the heat dissipation bar 26 and the heat sink 24 are fixed, the heat dissipation capacity cannot be increased by extending the length of the heat dissipation bar 26 during heat dissipation. However, if a longer heat dissipation bar 26 is directly used, the heat dissipation bar 26 will be too long and inconvenient to store, which increases the occupied space. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 14 An inner connecting rod 30 is slidably arranged inside the sliding rod 28, a heat conducting cavity 31 is provided inside the heat sink 24, a straight plate 32 is elastically connected inside the heat conducting cavity 31, a second abutting block 33 is fixed on the straight plate 32, an end of the inner connecting rod 30 abuts against the second abutting block 33, a plurality of third abutting blocks 34 are also fixed on the straight plate 32, an end of the heat sink 26 abuts against the third abutting block 34, and a connecting rod 35 is fixed on the heat sink 26, and the connecting rod 35 is elastically connected to the heat sink 24 through a third spring 36; The inner wall of the heat conduction cavity 31 is provided with a second groove 37, a protrusion 38 is fixed on the straight plate 32, the protrusion 38 is slidably disposed in the second groove 37, and a fourth spring 39 is disposed between the protrusion 38 and the inner wall of the second groove 37; In the present technical solution, when the heat sink 24 slides along the descending portion 293 with the slide bar 28, the slide bar 28 drives the inner rod 30 to move. While the inner rod 30 slides along the descending portion 293, it also slides along the inclined portion 294. Due to the resistance of the inclined portion 294 to the inner rod 30, the inner rod 30 moves toward the inside of the heat sink 24, so that the inner rod 30 resists the second resistance block 33 (such as Fig.12 The third spring 36 releases force to pull the heat dissipation bar 26 back into the heat conduction cavity 31, thereby facilitating the storage of the heat dissipation bar 26, and can increase the heat dissipation effect when the heat dissipation bar 26 is pushed out of the heat conduction cavity 31.
