[0017] The present application has the following advantages:

[0018] 1. In this VR headset, the positioning box's edge secures the phone. As the positioning box moves towards the phone, a power-accumulating component stores force. After storage, a release component releases the force, causing the power-accumulating component to release its force. This releases the force, driving the transmission rack to move. The transmission rack then moves the guide block, which contacts the first abutment block. The first abutment block slides along the lower surface of the guide block, causing the first abutment block to move the pressing block. This moves the pressing block a certain distance towards the phone, thus securing the phone. This design increases the stability of the phone inside the placement slot, preventing it from shaking. A heat-conducting plate is installed inside the positioning box. When the phone is pressed and fixed, a transmission gear drives a pressure roller to move along the heat-conducting plate, pressing it onto the phone's surface. The heat-conducting plate's excellent thermal conductivity dissipates heat from the phone's surface, facilitating heat dissipation. This improves heat dissipation when using VR glasses, avoiding the problems associated with using solid pressure plates to fix the phone and hindering heat dissipation.

[0019] 2. In this VR glasses, when the pressure roller moves along the surface of the heat-conducting sheet, the pressure roller drives the heat sink to move through the crossbar, connecting plate and first telescopic rod, and lays the heat sink flat on the heat-conducting sheet. When the heat sink moves, it drives the slide bar to slide in the track groove. After the heat sink is laid flat on the heat-conducting sheet, it will cause the heat sink to move a certain distance in the direction of the heat-conducting sheet, so that the heat sink will press the heat-conducting sheet tightly against the surface of the phone, thereby increasing the adhesion between the heat sink and the surface of the phone, making it easier for the heat sink to conduct heat to the phone, and also making it easier for the heat sink to absorb the heat transferred by the heat sink. Heat is dissipated through the heat sink and heat dissipation strip, which increases the heat dissipation effect.

[0020] 3. In this VR headset, when the heat sink moves a certain distance in the direction of the heat-conducting plate, it will cause the sliding rod to slide in the track groove, and also cause the inner connecting rod to slide in the track groove. When the heat sink completes the pressing of the heat-conducting plate, the inner connecting rod abuts against the second abutting block, causing the second abutting block to drive the straight plate to move. The movement of the straight plate drives the third abutting block to move, causing the third abutting block to abut against the heat dissipation strip, pushing the heat dissipation strip out of the heat-conducting cavity. After the heat dissipation strip is pushed out of the heat-conducting cavity, it is equivalent to extending the exposed length of the heat dissipation strip, which facilitates the increase of 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, pulling the heat dissipation strip back into the heat-conducting cavity, which facilitates the storage of the heat dissipation strip. It can increase the heat dissipation effect when the heat dissipation is in use, and reduce the space occupied by the heat dissipation strip when the VR headset is not in use, resulting in good performance.

[0044] The lifting rod 13 is fixed with a cross rod 20, the cross rod 20 is fixed with a push rod 21, the push rod 21 penetrates through the positioning box 5, and the positioning box 5 is provided with a slide 22 for the push rod 21 to slide;

[0045] In the technical solution, when the VR glasses are used, the positioning box 5 needs to be opened first, and the mobile phone 2 is placed in the placing groove 3 (as shown in Figure 1 After the mobile phone 2 is placed in the placing groove 3, the mobile phone 2 needs to be fixed, at this time, the positioning box 5 is pressed to move to the outside of the mobile phone 2 to limit the mobile phone 2;

[0046] When the positioning box 5 is pressed to move to the mobile phone 2, the positioning box 5 slides relative to the connecting rod 4, in 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 makes the torsional spring 85 store energy, 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 engaged with the driving rack 81, so that the first driving gear 82 cannot continue to rotate, at the same time, the convex block 121 is in contact with the convex strip 124, which promotes the movement of the convex strip 124, the movement of the convex strip 124 drives the limiting rod 123 to move, the limiting rod 123 moves to move the clamping block 125 out of the first elastic sheet 127 and the second elastic sheet 128, so that the clamping block 125 moves upwards of the first elastic sheet 127 (as shown in Figure 9 At this time, the limiting rod 123 is not in contact with the second driving gear 84, the second driving gear 84 is released, and the torsional spring 85 is released, because 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, the movement of the transmission rack 9 drives the guide block 10 to move, the guide block 10 is in contact with the first contact block 11, which makes the first contact block 11 slide along the lower surface of the guide block 10, so that the first contact block 11 drives the pressing block 7 to move, the pressing block 7 moves a distance towards the mobile phone 2, thereby completing the pressing treatment of the mobile phone 2, increasing the stability of the mobile phone 2 inside the placing groove 3, preventing the mobile phone 2 from shaking, the inside of the accommodating groove 6 is elastically connected with 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 distance towards the mobile phone 2, the fifth spring 41 stores energy, which is convenient for the subsequent resetting of the pressing block 7, through the second telescopic rod 42, when the first contact block 11 is in contact with the guide block 10, the pressing block 7 can only move towards the mobile phone, and when the pressing block 7 is reset, it moves in the opposite direction, and will not move in other directions;

[0047] Since the sixth spring 172 is initially compressed, it stores force. When the pressing block 7 moves a certain distance towards the mobile phone 2, it drives the heat-conducting sheet 15 on one side to move. At this time, the sixth spring 172 releases force, pushing 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-conducting sheet 15. The heat-conducting sheet 15 is a silicone heat-conducting sheet. While the transmission rack 9 moves, it drives the lifting rod 13 to move. The lifting rod 13 drives the pressure roller 14 to move, so that the pressure roller 14 presses the heat-conducting sheet 15, pressing the heat-conducting sheet 15 onto the surface of the mobile phone 2. At the same time, it pulls the support rod 16 to slide in the first groove 18. The support rod 16 presses the first spring 19, so that the first spring 19 stores force, and the end of the support rod 16 is set as a T-shaped structure, and the first groove 18 is set as a T-shaped groove, so that the support rod 16... When sliding within the first groove 18, it will not be pulled out, and the first spring 19 stores force to provide elasticity for the subsequent reset of the heat-conducting sheet 15. While the lifting rod 13 drives the pressure roller 14 to move, it also drives the crossbar 20 to move. The movement of the crossbar 20 drives the lever 21 to slide within the slide rail 22, sliding the lever 21 to the top of the slide rail 22. In this solution, after the positioning box 5 fixes the mobile phone 2, the pressing block 7 can first press and fix the mobile phone 2, increasing the stability of the mobile phone 2. Then, the pressure roller 14 presses the heat-conducting sheet 15 onto the surface of the mobile phone 2, using the heat-conducting sheet 15 to conduct heat to the surface of the mobile phone 2, facilitating the heat dissipation of the mobile phone 2. The outer surface of the positioning box 5 is set with a mesh structure, which is conducive to heat dissipation and ventilation. At the same time, it increases the pressing and bonding, effectively avoiding the effect of air between the heat-conducting sheet 15 and the surface of the mobile phone 2, resulting in better heat conduction.

[0048] When the positioning box 5 is opened, it slides away from the mobile phone 2 relative to the connecting rod 4. Since the second drive gear 84 is released from its restraint, the drive rack 81 drives the first drive gear 82 to reverse. The second drive gear 84 tends to rotate in the same direction as the first drive gear 82, but the transmission rack 9 cannot continue forward. The second drive gear 84 meshes with the transmission rack 9, preventing it from rotating. At this time, the torsion spring 85 stores force. After the positioning box 5 is fully opened, the drive rack 81 slides past the first drive gear 82 and loses mesh with it. When the torsion spring 85 releases its force, the first drive gear 82 resets, and then the lever 21 is moved to reset, which in turn drives the transmission rack 9 to reset. This resets the clamping block 7, the pressure roller 14, and the heat-conducting plate 15. Then, by pressing down on the button 129, the button 129 moves the limiting rod 123, which in turn moves the locking block 125 back between the first spring 127 and the second spring 128, so that the limiting rod 123 restricts the second drive gear 84 again, thus completing the reset of the entire structure. The VR glasses can then be used again.

[0049] Embodiment Two

[0050] This embodiment is an improvement based on Embodiment One. For details, please refer to Figures 1-14 , the crossbar 20 is further provided with a connecting plate 23, the connecting plate 23 is movably connected with a heat sink 24 through a first telescopic rod 40, the heat sink 24 is provided with a plurality of heat dissipation grooves 25, the two sides of the heat sink 24 are provided with a plurality of heat dissipation strips 26, the first telescopic rod 40 is sleeved with a second spring 27, the two ends of the second spring 27 are fixedly arranged on the connecting plate 23 and the heat sink 24, the heat sink 24 is fixedly provided with a sliding rod 28, the sliding rod 28 penetrates through the pressing block 7, and the inner wall of the positioning box 5 is provided with a track groove 29 for sliding of the sliding rod 28;

[0051] The track groove 29 comprises a vertical portion 291, a horizontal portion 292 and a descending portion 293 which are sequentially and communicatively arranged, and the inner wall of the descending portion 293 is further provided with an inclined portion 294;

[0052] In this technical solution, the heat sink 24 is slidably arranged on the inner side of the pressing block 7, the outer side of the pressing block 7 is provided with a gap 43 for sliding of the sliding rod 28, the sliding rod 28 is limited through the gap 43, so that when the pressing block 7 presses the mobile phone 2, the pressing block 7 drives the sliding rod 28 to move, the sliding rod 28 drives the heat sink 24 to move, the heat sink 24 drives the sliding rod 28 to move along the vertical portion 291 of the track groove 29, and then moves to the connection between the vertical portion 291 and the horizontal portion 292 (as shown in Figure 13 During the process that the pressing roller 14 presses the heat-conducting sheet 15 on the surface of the mobile phone 2, the pressing roller 14 drives the heat sink 24 to move through the crossbar 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 sliding rod 28, thereby pulling out the heat sink 24, and the heat sink 24 is laid flat on the surface of the heat-conducting sheet 15. In order to better dissipate the heat of the heat-conducting sheet 15 through the heat sink 24, and increase the adhesion of the heat-conducting sheet 15 to the surface of the mobile phone 2, and further increase the heat-conducting capacity of the heat-conducting sheet 15 to the mobile phone 2, when the heat sink 24 moves along with the sliding rod 28 from the horizontal portion 292 to the descending portion 293 of the track groove 29, the heat sink 24 will move a distance towards the heat-conducting sheet 15, and when the heat sink 24 moves towards the heat-conducting sheet 15, the second spring 27 will be stretched, so that the second spring 27 is charged, and at the same time, the first telescopic rod 40 is elongated, which is convenient for subsequent resetting of the heat sink 24. Since the silica gel heat-conducting sheet 15 has a certain elasticity, the heat sink 24 will press the heat-conducting sheet 15 tightly on the surface of the mobile phone 2, thereby increasing the adhesion of the heat-conducting sheet 15 to the surface of the mobile phone 2, which is convenient for the heat-conducting sheet 15 to conduct heat to the mobile phone 2, and is also convenient for the heat sink 24 to absorb the heat transferred by the heat-conducting sheet 15, and dissipate the heat through the heat sink 24 and the heat dissipation strips 26, thereby increasing the heat dissipation effect.

[0053] Embodiment Three

[0054] Because the position of the heat dissipation strip 26 and the heat dissipation fin 24 is fixed, it cannot increase the heat dissipation capacity by lengthening the length of the heat dissipation strip 26 when dissipating heat, but if a longer heat dissipation strip 26 is directly used, the heat dissipation strip 26 will be too long and inconvenient to store, increasing the occupied space. To solve this problem, the embodiment is improved on the basis of Embodiment Two. For details, please refer to Figures 1-14 , the inner connecting rod 30 is slidably arranged in the slide rod 28, the heat dissipation fin 24 is internally provided with a heat conduction cavity 31, the straight plate 32 is elastically connected in the heat conduction cavity 31, the second contact block 33 is fixed on the straight plate 32, the end of the inner connecting rod 30 is in contact with the second contact block 33, a plurality of third contact blocks 34 are fixed on the straight plate 32, the end of the heat dissipation strip 26 is in contact with the third contact block 34, and the connecting rod 35 is fixed on the heat dissipation strip 26 and elastically connected with the heat dissipation fin 24 through the third spring 36;

[0055] The inner wall of the heat conduction cavity 31 is provided with a second groove 37, the protrusion 38 is fixed on the straight plate 32, the protrusion 38 is slidably arranged in the second groove 37, and the fourth spring 39 is arranged between the protrusion 38 and the inner wall of the second groove 37;

[0056] In the technical solution, when the heat dissipation fin 24 slides along the descending part 293 with the slide rod 28, the slide rod 28 drives the inner connecting rod 30 to move, and the inner connecting rod 30 not only slides along the descending part 293 but also slides along the inclined part 294. Due to the contact of the inclined part 294 with the inner connecting rod 30, the inner connecting rod 30 moves towards the inside of the heat dissipation fin 24, so that the inner connecting rod 30 contacts the second contact block 33 (as shown in Figure 12 ), the second contact block 33 drives the straight plate 32 to move leftwards, the straight plate 32 drives the protrusion 38 to pull the fourth spring 39, the fourth spring 39 is charged, the straight plate 32 drives the third contact block 34 to move leftwards, the third contact block 34 contacts the heat dissipation strip 26, the heat dissipation strip 26 is pushed out of the heat conduction cavity 31, and the connecting rod 35 compresses the third spring 36, so that the third spring 36 is charged. After the heat dissipation strip 26 is pushed out of the heat conduction cavity 31, the effective length of the heat dissipation strip 26 is lengthened, so that the heat dissipation effect is increased. In addition, when the heat dissipation fin 24 is reset, the fourth spring 39 is discharged, the straight plate 32 moves rightwards, the second contact block 33 pushes the inner connecting rod 30 out of the slide rod 28 to reset, and the third spring 36 is discharged to pull the heat dissipation strip 26 back into the heat conduction cavity 31, so that the heat dissipation strip 26 is conveniently stored. The heat dissipation effect is increased when dissipating heat, the occupied space of the heat dissipation strip 26 is reduced when the VR glasses are not used, and the use effect is good.

[0057] It is to be noted that, as used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a component" can include a combination of two or more components, and the term "the item" can include multiple items unless the context clearly indicates otherwise. Also, the terms "comprise," "comprises" and "comprising" are to be construed as nonexclusive, that is, as meaning "comprises at least" or "comprising at least" rather than "comprises or consists of only."

[0058] The preferred embodiments of the present application described above are intended to be merely illustrative of the many possible applications of the principles of the present application. Numerous modifications and adaptations thereof will be apparent to those skilled in the art without departing from the spirit and scope of the present application as defined in the following claims.
