Referring to FIG. 24, FIG. 24 is a structural exploded view of a virtual reality device according to an embodiment of the present application.

The present application also provides a virtual reality device including a frame surrounded by a front case 1 and a rear case 3, two temples connected to the rear case 1 and an optical system built in the frame, a PCBA board 8, and a heat sink 9. The optical system is connected to the PCBA board 8, and the optical system includes mutually independent left barrel mechanism 21, right barrel mechanism 23, and left display screen 22 and right display screen 24 respectively mounted behind the two; heat sink 9 and left The display screen 22 and the right display screen 24 are attached to the rear and are attached to the heat generating device of the PCBA board 8.

As shown in FIG. 25 and FIG. 26(a), based on the content disclosed in the above embodiments, the present embodiment is different from the above embodiment in that the heat sink 9 includes a metal substrate 91 and a heat diffusion layer 92, which is thermally transparent. The layer 92 is disposed on a side of the metal substrate 91 facing the front case 1. The metal substrate 91 serves as a susceptor of the heat sink 9 so that the heat sink 9 can be held in a fixed state and also has a function of conducting heat. The material of the heat dissipation layer 92 is a material having good heat dissipation performance and capable of diffusing heat energy, preferably a material which is powdery and capable of forming a light and thin layer, such as graphene, since the normal state of graphene is powdery. It is necessary to adhere to the metal substrate 91 in order to have a fixed shape, so that the heat dissipation layer 92 and the metal substrate 91 uniformly form the heat sink. The heat diffusion layer 92 is uniformly attached to the surface of the metal substrate 91, so that the heat sink 9 has a function of uniformly dissipating heat. In practical applications, the heat dissipation layer 92 is a thin layer, avoiding occupying too much internal space of the virtual reality device, so that the virtual reality device is lighter and thinner.

The heat sink 9 is divided into a heat collecting zone 901 and a heat radiating zone 902 in the heat conduction direction. Since the heat radiated from the left display screen 22 and the right display screen 24 does not have a large amount of heat radiated from the heat generating component 81, the heat collecting zone 901 and the PCBA board are disposed. The heating element 81 on the 8 is attached, and the heat dissipation area 902 is attached to the rear of the left display 22 and the right display 24.

The heat collecting portion 901 absorbs the heat radiated by the heat generating element 81 during operation by the heat conductivity of the heat sink 9, that is, the heat radiated from the heat generating element 81 is conducted to the entire metal substrate 91; the metal substrate 91 located in the heat radiating portion 902 can also absorb the left display screen. 22 and the heat emitted by the right display 24. The metal substrate 91 transfers the heat absorbed by the heat collecting portion 901 to the heat diffusion layer 92 attached to the surface of the metal substrate 91, and the heat radiation layer 902 radiates heat by the heat radiation layer 902. The position of the heat collecting zone 901 and the heat radiating zone 902 is such that the fins 9 are L-shaped.

In order to realize the heat conduction, the material of the metal substrate 91 may be selected from a copper material or an aluminum material, and may be other materials, which is not specifically limited in this embodiment.

In this embodiment, the heating element 81 may include an MCU microcontroller, a SOC system level chip, a CPU central processing unit, a GPU graphics processor, a DSP digital signal processor, or an ISP image signal processor, and may also include a WiFi module and a modem. The specific components may be set according to actual conditions, and are not specifically limited in this embodiment.

The heating element 81, the left display 22 and the right display 24 are located on the same side of the metal substrate 91, so that the metal substrate 91 can simultaneously absorb the heat radiated from the heating element 81, the left display 22 and the right display 24, and the virtual reality device The heat generated during use is completely absorbed, and heat is radiated along the same heat conduction direction to improve the heat dissipation efficiency of the heat sink 9. The area of the metal substrate 91 in the heat collecting area 901 is smaller than the area of the metal substrate 91 in the heat dissipating area 902, so that the heat sink 9 has sufficient heat dissipation capability to avoid excessive heat accumulated on the metal substrate 91, and the heat dissipating area 902 cannot be timely. The heat is dissipated, which affects the use effect of the heat sink 9.

In an alternative embodiment, as shown in FIG. 24, the heat dissipation zone 902 of the heat sink 9 can cover half of the left display screen 22 and the right display screen 24. Under the premise of not affecting the heat dissipation effect of the heat sink 9, the volume of the heat sink 9 can be appropriately reduced, thereby reducing the weight of the virtual reality device to obtain a thin and light virtual reality device.

In another alternative embodiment, as shown in FIG. 27, the heat sinking area 902 of the heat sink 9 can be completely covered on the left display screen 22 and the right display screen 24. Although such an arrangement may increase the weight of the virtual reality device, since the heat diffusion layer 92 is only attached to a thin layer on the metal substrate 91, it does not increase the excessive weight burden; and the method of completely covering can be improved. The heat dissipation effect of the heat sink 9 is to radiate all the heat generated by each of the heat generating elements 81 in the virtual reality device.

As shown in FIG. 26(b), the virtual reality device provided by the embodiment of the present application may further employ a heat sink 9 further including a metal substrate 91 and a heat generating component 81, and a metal substrate 91. And a thermally conductive gel layer 93 between the left display screen 22 and the right display screen 24.

In order to allow the heat sink 9 to be stably attached to the heat generating element 81, the left display panel 22, and the right display panel 24, it is necessary to provide the heat conductive gel layer 93 on the side where the heat sink 9 and the heat generating element 81 are bonded. The thermally conductive gel layer 93 has heat-conducting properties and serves to seamlessly bond the heat-collecting zone 901 to the heat-generating component 81 on the PCBA board 8, and to provide the heat-dissipating zone 902 with the left display screen 22 and the right display screen 24. No gaps in the back.

Since the metal substrate 91 itself has a plastic property, it is not easy to be formed into a completely smooth plane, and the heat generating element 81, the left display screen 22, and the right display screen 24 respectively have regular planes. Therefore, when the metal substrate 91 is attached to the heat generating element 81, the left display panel 22, and the right display screen 24, a gap is formed at the corresponding position. The occurrence of the gap tends to reduce the efficiency with which the heat generating component 81, the left display panel 22, and the right display panel 24 dissipate heat to the metal substrate 91, so that some of the heat generated by the heat generating component 81, the left display panel 22, and the right display panel 24 remains. The inside of the virtual reality device, which in turn affects the use effect of the virtual reality device.

Therefore, in the present embodiment, the thermally conductive adhesive layer 93 is used to fill the gap between the metal substrate 91 and the heat generating component 81, the left display panel 22 or the right display panel 24, thereby achieving the effect of seamless bonding. The seamless gap bonding can increase the contact area of the heat sink 9 with the heat generating component 81, the left display screen 22, and the right display screen 24, so that the heat radiated by each device during operation can be completely conducted on the metal substrate 91 and passed through the heat. The diffusion layer 92 radiates heat, which in turn improves the heat dissipation efficiency of the heat sink 9.

As shown in FIG. 26(c), the virtual reality device of the embodiment of the present application may further adopt another heat sink 9, which further includes a heat collecting portion disposed on the side of the heat collecting portion 901 and the heat generating component 81. Layer 94. Specifically, the heat collecting layer 94 is disposed between the metal substrate 91 and the heat generating component 81. The heat collecting layer 94 is disposed only in the heat collecting region 901 and is connected to the heat conductive gel layer 93 of the heat radiating region 902.

The heat collecting layer 94 is non-grooved with the heat generating component 81 on the PCBA board 8; the heat sink 9 is provided with a heat conductive gel layer 93 on the side where the heat radiating region 902 is attached to the heat generating component 81, and the heat conductive gel layer 93 is used for The heat dissipation zone 902 is bonded to the rear of the left display screen 22 and the right display screen 24 without gaps.

In the heat sink 9 provided in this embodiment, two layers of heat dissipation layer 92 are disposed at the heat collecting portion 901, which can increase the heat absorbing capability of the heat sink 9, and thereby absorb all the heat generated inside the virtual reality device to be radiated to The outside world increases the heat dissipation efficiency of the heat sink 9.

As shown in FIG. 26(d), the virtual reality device provided by the embodiment of the present application may further employ another heat sink 9, which is different from the previous embodiment in that between the heat collecting layer 94 and the heat generating component 81. A heat collecting gel layer 95 is provided, and the heat collecting gel layer 95 is used to seamlessly bond the heat collecting layer 94 with the heat generating element 81 on the PCBA board 8.

Specifically, the heat collecting gel layer 95 is disposed in the heat collecting region 901, and the heat collecting layer 94 is adhered to the heat collecting gel layer 95, and the sum of the widths of the two is the same as that of the heat conductive gel layer 93 disposed in the heat radiating region 902. The heat collecting gel layer 95 is connected to the heat conductive gel layer 93 with the same width.

The functions and beneficial effects of the heat-collecting layer 93 provided in the previous embodiment can be referred to the functions and benefits of the heat-collecting layer 95 in this embodiment.

As shown in FIG. 28( a ), the virtual reality device provided in this embodiment further includes another heat sink, that is, the first radiation piece 70 . Specifically, in the embodiment, the first radiation piece 70 is disposed at a position corresponding to the heat dissipation area 902 inside the front case 1 . The first radiating sheet 70 is used to radiate heat absorbed by the fins 9 from the front case 1.

The first radiating sheet 70 includes a first metal layer 701 and a heat radiating layer 702. The heat radiating layer 702 is located between the front shell 1 and the first metal layer 701. The first metal layer 701 is fastened after the front shell 1 and the rear shell 3 are fastened. Contact with the thermal diffusion layer 92 of the heat dissipation region 902. The function and structure of the first metal layer 701, and the beneficial effects that can be obtained are the same as those of the metal substrate 91 provided in the above embodiments. For the corresponding parts, reference may be made to the metal substrate 91 in the above embodiment, and details are not described herein. . The heat radiation layer 702 is attached to the first metal layer 701 in the form and structure, and is also in the same form and structure as the thermal diffusion layer 92 is attached to the metal substrate 91, and the heat radiation layer 702 functions and thermally diffuses. The function of the layer 92 is the same, and therefore, the role of the heat radiation layer 702 will not be described again. At the same time, the two may be the same material, or may be different, and may be set according to actual needs, which is not specifically limited in this embodiment.

In an alternative embodiment, corresponding to the heat sink 9 shown in FIG. 24, in the present embodiment, the first radiation sheet 70 covers only a half area inside the front case 1. The size and shape of the first radiating sheet 70 are the same as the size and shape of the heat dissipating region 902 of the fin 9, so that the heat absorbed in the fin 9 can be completely transmitted to the first radiating sheet 70, and the heat radiating layer 702 radiates heat to the heat radiating layer 702. The outside of the front case 1. Covering only half of the first radiating sheet 70 on the inner side of the front case 1 can reduce the weight of the virtual reality device while ensuring the heat dissipation efficiency of the heat sink 9.

In another optional embodiment, corresponding to the heat sink 9 shown in FIG. 27, the first radiation sheet 70 provided in this embodiment is as shown in FIG. 28(b), and the first radiation sheet 70 is covered. On the entire area inside the front case 1. According to the introduction of the above embodiment, the size and shape of the first radiating plate 70 are the same as the size and shape of the heat radiating region 902 of the heat sink 9, so that the heat absorbed in the heat sink 9 can be completely transmitted to the first radiating film 70, by the heat. The radiation layer 702 radiates heat to the outside of the front case 1. While covering the first radiation piece 70 on the inner side of the front case 1 also increases the weight of the virtual reality device, since the first metal layer 701 and the heat radiation layer 702 are both thin layers, the weight is not increased; Moreover, by increasing the area of the first radiation sheet 70, the efficiency of heat dissipation can be increased, and the heat dissipation efficiency of the heat sink 9 can be improved.

The heat dissipation system in the virtual reality device works by the fact that the heating element 81 disposed inside the virtual reality device, as well as the left display 22 and the right display 24, generate heat during operation. In the present embodiment, the side on which the heat sink 9 is provided with the metal substrate 91 is bonded to the above-mentioned object capable of generating heat. Specifically, the heat collecting portion 901 of the heat sink 9 is bonded to the heat generating component 81, and the heat radiating region 902 of the heat sink 9 is bonded to the left display screen 22 and the right display screen 24. The metal substrate 91 absorbs the heat radiated from the heat generating component 81, the left display panel 22, and the right display panel 24, and is transferred to the first radiating sheet 70 through the thermal diffusion layer 92, and finally by the heat radiating layer 702 on the first radiating sheet 70, With its heat radiation characteristics, the heat is completely dissipated to the outside of the front case 1 to achieve the heat dissipation effect. The heat dissipation efficiency of the heat sink 9 can be improved by the heat conduction of the first radiation sheet 70 and the heat sink 9.

In the above embodiment, the heat sink 9 and the first radiation sheet 70 are directly bonded together, as shown in FIG. 29 (1), the heat dissipation layer 92 on the heat dissipation region 902 of the heat sink 9 and the first radiation sheet 70. The upper first metal layer 701 is directly attached. Although the two directly fit the heat transfer, it is also easy to disassemble when the virtual reality device fails. However, during the use of the virtual reality device, the user's action may have a certain influence on the virtual reality device, causing collision or squeezing between the internal devices, and at this time, the heat sink 9 and the first radiation piece 70 may be caused. Misalignment occurs between them, thereby affecting the heat dissipation efficiency of the heat sink 9.

To this end, in another embodiment, as shown in FIG. 29 (2), a thermal conductive paste 703 is further disposed between the first metal layer 701 and the thermal diffusion layer 92 of the heat dissipation region 902. The thermal conductive paste 703 has the same function as the thermal conductive adhesive layer 93, and can be used for heat conduction, and the heat sink 9 can be fixed to the first radiation sheet 70. However, the adhesion of the thermal conductive paste 703 is not as strong as that of the thermal conductive adhesive layer 93, and therefore, even if the virtual reality device needs to be disassembled in the event of a malfunction, the heat sink 9 and the first radiation piece 70 can be easily separated. Although the thermal grease 703 has a lower adhesive force than the thermal adhesive layer 93, it is sufficient to fit the heat sink 9 and the first radiating film 70, that is, during the use of the virtual reality device, there is no case where the two are separated or misaligned, and thus It does not affect the heat dissipation effect of the heat sink 9.

The virtual reality device provided by another embodiment of the present application, as shown in FIG. 30 (1), the first radiation piece 70 adopts an arc structure, that is, the center of the first radiation piece 70 extends toward the heat dissipation area 902. Since the first radiation piece 70 is a thin structure and is easily deformed, the bending center and the heat dissipation of the first radiation piece 70 during the process of fastening the front case 1 with the first radiation piece 70 to the rear case 3 The region 902 is in contact with and gradually approaches the distance between the front case 1 and the rear case 3 until the two are fastened together, the first radiation piece 70 is deformed to enlarge the first radiation piece 70 and the heat dissipation area 902. Contact area to increase heat dissipation. The state diagram after the snap-in is shown in Figure 30 (2).

In other embodiments, the heat sink 9 used in the virtual reality device may also adopt other structures, for example, the heat sink 9 having a heat dissipation area 902 having an area larger than three times the area of the heat collection area 901. The heat dissipation zone 902 extends away from the heat collecting zone 901 toward both sides of the rear case 3, so that the area of the heat dissipation zone 902 covering the left display screen 22 and the right display screen 24 is larger than the area of the left display screen 22 and the right display screen 24, respectively. one third. By using the heat sink 9 provided in this embodiment, the weight of the heat sink 9 can be reduced as much as possible without affecting the heat dissipation effect of the heat sink 9, thereby reducing the weight of the virtual reality device.

In addition, the area of the first radiation piece 70 may be made larger than the area of the heat dissipation area 902, and the first radiation piece 70 and the heat dissipation area 902 extend in the same direction. Since the first radiating sheet 70 is used to radiate heat to the heat radiating region 902 to the outside, in order to increase the effect and rate of radiating heat outward, the area of the first radiating sheet 70 may be appropriately increased to be larger than the heat dissipation of the heat sink 9. The area of zone 902.

When the heat dissipation region 902 completely covers the rear of the left display screen 22 and the right display screen 24, the area of the first radiation sheet 70 is larger than the area of the heat dissipation region 902. The beneficial effects obtained thereby can be referred to the above-mentioned contents correspondingly, and will not be described herein.

In the virtual reality device provided in this embodiment, the internal heat is dissipated through the front case 1, but in order to prevent heat from accumulating at the rear case 3, a heat dissipation layer is also disposed at the rear case 3.

Specifically, the rear case 3 is disposed at a position relative to the heat generating component 81, and is provided with a second radiating sheet 50; the second radiating sheet 50 includes a second metal layer 501 and a rear case heat transparent layer 502, and the rear case 3 and the rear case are thermally permeable. The layer 502 is attached.

The working principle of the second radiating sheet 50 disposed in the rear case is the same as that of the heat sink 9 and the first radiating sheet 70. Therefore, the working process of the second radiating sheet 50 and the beneficial effects obtained can be referred to the heat sink 9 correspondingly. Or the content disclosed by the first radiation sheet 70 will not be described herein.

As can be seen from the above technical solutions, the present application provides a virtual reality device including: a frame surrounded by a front case 1 and a rear case 3, an optical system built in the frame, a PCBA board 8 and a heat sink 9. The heat sink 9 includes a metal substrate 91 and a heat dissipation layer 92 disposed on the surface of the metal substrate 91, and divides the heat sink 9 into a heat collecting region 901 for absorbing heat and a heat radiating region 902 for radiating heat in the heat conduction direction. . The heat generated by each device inside the virtual reality device is absorbed by the metal substrate 91 and transmitted to the heat diffusion layer 92, and the heat radiation characteristics of the heat diffusion layer 92 are used to radiate heat to the outside. At the same time, the first radiation piece 70 is disposed on the inner side of the front case 1 and is bonded to the heat diffusion layer 92. The heat dissipation of the heat dissipation piece 9 can be improved by the heat conduction of the first radiation piece 70 and the heat dissipation plate 9. Moreover, since the thermal diffusion layer 92 and the first radiation sheet 70 are both thin layers, the virtual internal device does not occupy too much internal space, and thus does not affect the thin and light characteristics of the virtual reality device, so that the virtual reality device Under the premise of light and thin characteristics, it has the characteristics of high heat dissipation efficiency. It can be seen that the heat sink 9 is used to realize the heat dissipation of the internal device, and the sensitivity of the corresponding device is not affected, thereby not affecting the use effect of the virtual reality device, and the user experience can be improved.

In the present application, the heat of the PCBA board 8 with relatively concentrated heat is quickly transmitted to the metal substrate 91 on the back of the display screen, that is, a relatively small heat dissipation surface is first expanded into several heat dissipation surfaces, and then the enlarged heat dissipation is performed. The surface transfers heat to the first metal layer 702 of the front case 1 which is closest to the outside air, so that the heat can be quickly dissipated and simultaneously dissipated together with the heat generated when the display is operated. Further, a surface of the first metal layer 702 that is in contact with the front case 1 is provided with a heat radiation layer 702 having thermal energy penetrating radiation, so that heat energy can be quickly diffused from the front case 1 to the outside air. It can be seen that the heat dissipation system provided by the present application can effectively implement virtual reality without requiring additional fan or air conditioner, and without major changes to the overall structure and layout of the original virtual reality device. The heat inside the device is dissipated.
