Since the display and the heat sink are only partially bonded, it is easy to disassemble during the maintenance process.

Since the chip of the PCBA board has a relatively large heat generation, the heat of the PCBA board is sufficiently dissipated. Therefore, the surface of the heat generating component of the PCBA board can be coated with the thermal conductive adhesive and connected to the heat sink 9.

Considering that the light-sensing component is also blocked by the heat sink 9, in order to facilitate maintenance, a maintenance opening can be provided at the heat sink corresponding to the light-blocking component or other heat-shielding device, so that the maintenance can be performed later, and the maintenance process is avoided. The entire heat sink needs to be removed for repair.

The present application also provides a virtual reality device assembly including a front case 1, a rear case 3, and a face support 6 disposed on the rear case 3. It should be noted that the virtual reality device component provided by the present application includes, but is not limited to, the front case 1 and the rear case 3 and the face support 6 disposed on the rear case 3. In actual use, in order to achieve wearing, the utility model also includes setting The temples on both sides of the rear case 3, and the inside of the front case 1 and the rear case 3, for displaying electronic components such as a driving circuit, a display screen, a sensor, a microprocessor, etc., are also included for improvement Optical components that display effects, such as lenses, lens barrels, and focusing devices. Through the cooperation of the various parts, the display of the virtual reality image is completed.

In the present embodiment, the rear case 3 is provided to have a cavity structure having a U-shaped cross section, and the rear case 3 is provided with two circular holes symmetrical with respect to the center line 601 for mounting the optical component. Obviously, the size of the circular hole should correspond to the size of the outer wall of the lens barrel of the optical component, that is, the size of the circular hole is sufficient to pass through the outer wall of the lens barrel of the optical component, and no large gap is created to facilitate positioning and dust prevention. Entry. It is not difficult to understand that in the present embodiment, the structure of the rear case 3 is described by taking a circular hole as an example. For those skilled in the art, in order to adapt to different shapes of optical components, it is easy to think of the rear case 3. The hole-shaped structure is provided in any shape. For example, protrusions of various shapes are provided on the outer wall of the lens barrel for the purpose of fixing, and the hole-shaped structure on the corresponding rear case 3 may correspond thereto.

Further, the rear case 3 includes a main body fitting surface 31 and an auxiliary positioning surface 32 extending toward the front housing 1 at the edge of the main body bonding surface 31. In order to increase the aesthetics of the overall structure, and to make the virtual reality device more light and thin, the main body fitting surface 31 is a plane, which is parallel to the screen during actual wearing. The auxiliary positioning surface 32 is a curved surface extending from the main body bonding surface 31 in the direction of the front housing 1. It is not difficult to understand that the distance that the auxiliary positioning surface 32 extends in the direction of the front housing 1 is the same as that of the front housing 1 and the rear housing 3. Installation distance between. In actual use, the extension distance of the auxiliary positioning surface 32 should be determined according to the model of the virtual reality device, the number of components in the device, and the focusing distance of the optical component.

The front case 1 has the same contour shape as that of the rear case 3, and is connected to the auxiliary positioning surface 32 to form a cavity for housing the optical component and the electronic device. The front shell 1 is generally a flat surface or has a smooth transition surface. In the actual mounting position, the edge of the front shell 1 can completely coincide with the edge shape of the main body mating surface 31 of the rear shell 3, and at this time, the auxiliary positioning surface 32 and the front are respectively The shell 1 and the body fitting surface 31 are perpendicular to each other as a middle frame of the lens body; in order to be more comfortable when worn, in another embodiment of the present application, the auxiliary positioning surface 32 is at the top position of the rear case 3 and the body bonding surface 31. Vertically, at the bottom position of the rear case 3, it is inclined with respect to the main body fitting surface 31, and the direction of the inclination is a direction away from the face so as to leave a sufficient mounting distance between the face and the auxiliary positioning surface 32.

In the virtual reality device assembly provided by the present application, the face rest 6 is a zigzag structure composed of a flange 602 disposed at the center line 601 and two curved portions 603 extending away from the flange 602. Also, the face rest 6 further includes a side contact segment 604 and a central contact segment 605 that extends from the flange 602 to the side contact segment 604. Wherein, the side contact segment 604 is adapted to conform to the wearer's face when worn, and the middle contact segment 605 is adapted to conform to the wearer's nose when worn. In actual use, the face support 6 disposed in the middle of the rear case 3 is also symmetric with respect to the center line 601. The flange 602 is located on the center line 601 and can be fitted to the top position of the wearer's nose bridge to prevent the top position from being generated. Light leakage reduces the effect of light in the external environment on the viewing effect.

In this embodiment, on the face support 6, in the direction away from the flange 602, the middle contact section 605 and the side contact section 604 are sequentially defined, and the middle contact section 605 and the side contact section 604 have the same contour as the facial contour. In the shape, it is apparent that the central contact section 605 conforms to the shape of the bridge of the nose, and the side contact section 604 conforms to the shape of the contact section of the lower end of the bridge of the nose that transitions to the position of the tibia on the cheek.

Further, in order to increase the stability of the overall structure, the face support 6 and the rear case 3 are integrally formed. That is, a convex structure having a zigzag structure and conforming to the shape of the surface of the face is provided on the rear case 3. In the actual wearing, the face support 6 and the rear case 3 are arranged as a whole, and the main body part of the face support 6 and the back case 3 need to be the same material, but the rear case 3 is generally made of hard plastic, and the plastic is The material does not perfectly fit the wearer's facial structure, and for different wearers, the facial structure is quite different, and the device may also cause a matching gap that affects the viewing effect when the device is switched between different users. For example, for a fat-faced user, facial muscles and fat are more, facial contours have less variation in the shape of the concave and convex, and for a body-worn wearer, facial muscles and fat are less, and facial contours are affected by the shape of the skull, generally presenting The phenomenon that the unevenness changes greatly. In addition, the difference in skulls between different races is large, which makes it more difficult for the face support 6 made of hard materials to fit the facial structure of different wearers.

In order to meet the requirements of the facial contour structure of the facial contour difference between different users, in this embodiment, a buffer layer made of a soft material should be disposed on the plastic material surface of the face support 6, and the buffer layer is soft. Made of sponge or foam material. Further, the position of the buffer layer in contact with the face should be adapted to the shape of the entire face support 6, for example, the thickness of the middle contact section 605 is thin, and the buffer layer of the side contact section 604 is thick, and is subjected to pressure. The fitting portion is thicker and the transition portion is thinner. In order to make a deformation of the soft material under the condition of extrusion, it can fully conform to each facial structure, and adapt to the difference of the facial contour between different wearers.

In some embodiments of the present application, the point at which the face support 6 is at a maximum relative to the thickness L of the body-fitting surface 31 constitutes a continuous fit curve 635. Obviously, the point of the maximum thickness L constitutes a continuous fit curve 635. The entire fit curve 635 changes as the shape of the entire face rest 6 changes. The conforming curve 635 forms a raised convex structure on the entire face support 6, and forms a fitting surface 636 and an outer edge supporting surface 637 on both sides of the fitting curve 635, respectively.

For the bonding surface 636, it is a continuously extending smooth curved surface formed on the side of the fitting curve 635 near the inner edge 631, and the surface curvature perpendicular to the bonding surface 636 should conform to the facial structure of the human body, so that it is located at two The bonding surface 636 of the middle contact section 605 is attached to both sides of the wearer's nose; the bonding surface 636 located at the two side contact sections 604 is attached to both sides of the wearer's face, which can not only increase The contact area of the user's face, which in turn reduces the bearing capacity per unit area, and is convenient for the user to wear for a long time to improve the user's comfort; in addition, the user of different nose shapes and face shapes can be well adapted.

The outer edge support surface 637 is a curved surface on the side of the fit curve 635 near the outer edge 632, and the outer edge support surface 637 is bonded to the optical module of the virtual reality device. In order to facilitate the adjustment of the imaging distance, for a wearer of different visual conditions, the virtual reality device often sets an optical module between the screen and the human eye. The general optical module includes a lens barrel and a lens disposed inside the lens barrel. Since the adjustment distance is required, the optical module is mounted on the rear case 3 of the virtual reality device through the mirror hole 311 provided on the main body bonding surface 31. And a protrusion having a certain distance with respect to the main body bonding surface 31. Therefore, in the technical solution provided by the present application, the outer edge supporting surface 637 and the optical module protrude from the outer wall of the lens barrel of the rear case 3, which can not affect the adjustment of the optical module, and can avoid the outer edge supporting surface 637 and A gap is formed between the rear shells 3 to cause light leakage, which affects the viewing effect.

Further, in this embodiment, the fitting curve 635 is on the face support 6 near the outer edge 632. Such a structure, on the one hand, can make the width of the abutment surface 636 larger, so as to obtain a larger fit. The area can be more adjusted between different users; on the other hand, the fitting curve 635 is closer to the outer edge 632, and the convex position corresponding to the fitting curve 635 can be located in the direction close to the outer edge 632, which can be attached. On the joint surface 636, the position that does not fit the face forms a structure that blocks light from entering, thereby reducing light leakage.

In order to sufficiently conform to the shape of the face of the wearer, the fitting surface 636 is inclined with respect to the main body bonding surface 31, and the formed inclination angle α is continuously changed over the entire face support 6. It should be noted that since the bonding surface 636 is a curved surface and the main body bonding surface 31 is a flat surface, an infinite number of angles are formed when the two are inclined. Therefore, in the present application, the fitting inclination angle α means that a tangent line is formed at any point on the fitting curve 635, and a point on the pasting curve 635 is determined in a direction perpendicular to the tangent line, and the fitting surface 636 is The angle formed by the extended surface of the main body bonding surface 31. Obviously, as shown in the section corresponding to each point, the abutment surface 636 appears as a straight line that is inclined with respect to the body abutment surface 31.

In one embodiment, the transition angle α is gradually increased from the flange 602 to the middle contact portion 605; the transition angle α is gradually decreased from the middle contact portion 605 to the side contact portion 604. The change in the conforming inclination angle α formed by the bonding surface 636 and the main body bonding surface 31 can satisfy the facial contour feature such that the bonding surface 636 of the face support sufficiently conforms to the nose side and the cheek. Thereby, the facial area in contact with the virtual reality device tends to be consistent, increasing the area of contact with the user's nose and face, giving the user a comfortable wearing feeling, and making the face support 6 together with the virtual reality device It is more stable. In addition, the sufficient fit of the bonding surface 636 and the face can also reduce the occurrence of light leakage at the bonding portion, improve the viewing effect, and avoid the use of a large hood, thereby helping to reduce the overall weight of the virtual reality device. The virtual reality device is not easily affected by gravity when worn, and is out of the face position.

In some embodiments of the present application, the side contact segments 604 are gradually tapered along the conforming curve 635, and the thickness L in the direction away from the central contact segment 605 is gradually increased. Since the inward angle α is gradually reduced on the side contact section 604 in a direction away from the middle contact section 605, a fitting surface 636 for fitting the cheek portion of the wearer can be formed. But most people's cheekbones are raised so that the height of the sides of the cheeks is slightly higher than the position near the bridge of the nose. If the angle of the inward angle α is changed only to adapt to the wearer's facial structure, the contact area at the cheek near the bridge of the nose is too small, and the weight is increased, and the stability of the entire structure at the time of wearing is also reduced. Therefore, in the present embodiment, by changing the thickness L, the thickness L of the entire face contact portion 63 on both sides of the bridge of the nose is maximized, and the thickness L of both sides is gradually reduced, so that the area where the bonding surface 636 fits the contour of the face is completed. It is possible to achieve the maximum while reducing the volume of the entire face support, thereby reducing the weight of the face support, thereby ensuring the overall stability of the face support and the virtual reality device as a whole.

Further, the maximum value of the thickness L corresponds to a point on the side contact section 604 at a position of 45% to 55% of the curve 635. It should be noted that the proportional relationship in the fitting curve 635 referred to herein is The fit curve 635 at the portion of the side contact segment 604 is an area and does not refer to the entire fit curve 635. And in the above ratio, the flange 602 is used as a starting point and is determined in the direction of the side contact section 604. Therefore, in the present embodiment, the maximum value of the thickness L corresponding to the region of 45% to 55% of the fitting curve 635 means the portion of the side contact portion 604, and the maximum point of the thickness L appears along the fitting curve 635. Location near the middle. Because when the user wears the virtual reality device, the part just corresponds to the position of the frontal bone of the human body, which can facilitate contact with the frontal bone of the user, and the force is transmitted to the frontal bone, so that the user does not easily feel wearing it for a long time. weight.

The present application for the side contact section 604 refers to the area formed between the ends 606 from the contact position on both sides of the bridge of the nose. For the side contact section 604, the 50% position of the fit curve 635 corresponds to the wearer. A recessed area formed between the bridge of the nose and the tibia. For facial parameters of different human bodies, there is a range of deviation of ±5%. For example, for Asians, the distance between the humerus on both sides is relatively close, so that the point corresponding to the maximum value of the thickness L should be set at 55% of the fit curve 635, and for the distance between the humerus in Europe. For the race, it is necessary to appropriately adjust the point corresponding to the maximum value of the thickness L so as to be located at the 45% position of the fitting curve 635.

In addition, in the present embodiment, after the side contact portion 604 satisfies the maximum value of the thickness L at 45% to 55% of the bonding curve 635, the minimum value of the thickness L is also required to be 50% to 60% of the maximum value. For virtual reality devices of different user types, there is a big difference in the overall size. For example, for virtual reality devices used by children and adults, there are differences in models, and the corresponding thickness L also has a large difference. However, since the ratio of the facial contour is substantially fixed, in the present embodiment, the minimum value of the thickness L on the side contact section 604 is limited to 50% to 60% of the maximum value to suit the contour of the majority. Similarly, due to differences in facial structure between different races, and due to the influence of fat and thin body shape, there are certain facial differences among the same races. For example, for Europeans with higher tibia, thickness should be made. The minimum value of L is 50% of the maximum value to accommodate Europeans with higher facial bulges, while for Asians with flat faces, the minimum value of thickness L should be maintained at 60% of the maximum.

In addition, for the wearer, the wearer who is generally thin, the face protrusion is relatively obvious, and the obese wearer has a relatively small face protrusion, so in different types of virtual reality devices, it should also be based on The actual wearing situation determines the most appropriate proportional relationship within the above range. Of course, it should be understood that the ratios, maximum values, minimum values, and specific ratio ranges in the embodiments of the application are only a range for popularization, and specific values may be changed according to actual conditions, such as for certain Customization of special people can be done without departing from the essence of the application. In this embodiment, by fitting the virtual reality device, it fits perfectly with the nose and the face of the human body as much as possible; by increasing the contact area and reducing the bearing capacity per unit area, the user is prevented from wearing the virtual reality device for a long time. Uncomfortable and wearing stability issues.

In some embodiments of the present application, the middle contact segment 605 along the conforming curve 635, the thickness L in the direction away from the flange 602 gradually increases, and the minimum value of the thickness L in the middle contact segment 605 is 50% of the maximum value. ~60%. For the middle contact section 605, during actual wear, it is the area that fits the sides of the nose of the wearer. In this region, the angle of inclination of the sides of the bridge of the nose to the face gradually becomes smaller as the height of the bridge of the nose gradually becomes larger from the top of the bridge of the nose, that is, in the direction away from the midline section 602.

Similarly, by the variation of the inward angle α in the middle contact section in the above embodiment, although the abutting surface 636 of the middle contact section 605 can be fitted to both sides of the bridge of the nose, the bridge of the nose is gradually transitioned from the top of the bridge of the nose. The increase in the height will gradually reduce the fit area of the face support, and for some wearers with higher nose bridges, even the sides of the bridge of the nose and the fit surface 636 may be separated. Therefore, in order to avoid the occurrence of the above situation, in the embodiment, the middle contact section 605 along the fitting curve 635, the thickness L in the direction away from the flange 602 gradually increases, and the thickness L gradually increases with the majority of the nose bridge. The law of change in height is consistent.

Further, the minimum value of the thickness L of the middle contact section 605 is 50% to 60% of the maximum value, and for the wearer with a smaller nose height, the thickness L between the maximum and minimum thicknesses of the middle contact section 605 should be The proportional relationship is large to avoid an increase in the overall weight of the bonding surface 636; and for a wearer with a higher nose bridge, the proportional relationship between the maximum and minimum thickness L should be reduced to increase the fit. The fit area of the face 636 on either side of the bridge of the nose increases overall stability.

In one embodiment of the present application, the flange 602 is tapered along the conforming curve 635 in a direction L that is away from the central contact segment 605. Since the flange 602 is a flange structure that is symmetrical with respect to both sides of the center line 601, the thickness L of the flange 602 in the direction away from the middle contact portion 605 gradually decreases in the region on both sides of the center line 601, meaning that The thickness L of the flange 602 at the centerline 601 reaches a minimum. Such a configuration allows the flange 602 to conform to the top position of the bridge of the nose, increasing overall stability while avoiding light leakage at the top of the bridge of the nose.

Further, the minimum value of the thickness L of the flange 602 is 10% to 15% of the maximum value. Since the position in contact with the top of the bridge of the nose does not endure much of the weight of the virtual reality device as a whole, it is only shaded at the top of the wearer's bridge of the nose. Therefore, there should be a large difference between the minimum value and the maximum value. To accommodate the entire top structure of the bridge of the nose. Additionally, at the conforming position of the top of the bridge of the nose, the overall thickness L of the flange 602 should be thinner than the thickness L of the central contact section 605 and the side contact section 604 to reduce the overall weight.

In order to present the screen on the screen in the virtual reality device directly in front of the wearer's eyes, in some embodiments of the present application, the two mirror holes 311 provided on the rear case 3 are symmetric with respect to the center line 601. relationship. For most virtual reality devices, the screen and optical components located in front of both eyes when worn are symmetrically related to the centerline 601, and the axis of the lens barrel in the optical assembly is generally perpendicular to the screen, so that in order to fit in the screen The mirror hole 311 on the rear case 3 also has a symmetrical relationship, and the mirror hole 311 should be in line with the central axis of the optical component and the center point of the screen.

In addition, as shown in FIG. 24, in the lens body provided by the present application, the position corresponding to the middle contact portion 605 is on the cross section perpendicular to the tangent to the fitting curve 635, and the circumferential surface of the mirror hole 311 is between the center line 601. The distance is greater than or equal to the distance between the outer edge support surface 637 and the centerline 601. At a position corresponding to the middle contact section 605, that is, a position to be fitted to both sides of the nose bridge of the wearer, the distance from the circumferential edge of the mirror hole 311 closest to the center line 601 to the center line 601 is ensured to be larger than the face support 6 The distance between the upper outer edge 632 and the inner edge 631.

During the actual wearing process, the distance between the mirror hole 311 and the center line 601 corresponds to the distance between the wearer's eye and the bridge of the nose. This distance should not be too large, because the position of the optical component is biased to both sides, possibly Does not match the position of the wearer's eyes, affecting the viewing experience; the distance should not be too small, because too small a distance will cause the optical components to be deflected inward, squeezing the central area of the virtual reality device, reducing the face support 6 in the nose Fit the area. Therefore, the distance between the mirror hole 311 and the center line 601 should be appropriately increased without affecting the viewing experience. Further, in the present embodiment, the distance between the circumferential surface of the mirror hole 311 and the center line 601 is set to be greater than or equal to the distance between the outer edge 632 and the inner edge 631 in the same cross section. Such a structure does not compress the width of the face support 6 at the position of the middle contact section 605, so that the face support 6 can provide a sufficient area of the fit surface 636 in the middle contact section 605, and can also satisfy the spacing of the two eyes of most people, Affect the user's viewing experience.

In some embodiments of the present application, the distance between the inner edge 631 of the face rest 6 and the outer edge 632 gradually increases in the direction of the central contact section 605 away from the flange 602. Since the flange 602 corresponds to the position of the eyelid, the middle contact section 605 corresponds to the position on both sides of the bridge of the nose, and the width of the nose gradually becomes larger during the transition from the eyelid to the sides of the bridge of the nose, which can be used for the face area to be fitted. The area is also gradually increased. Therefore, in order to increase the bonding area of the bonding surface 636, the face support 6 gradually increases the distance between the inner edge 631 and the outer edge 632 on the central contact portion 605. In addition, the progressive increase in distance between the inner edge 631 and the outer edge 632 on the central contact segment 605 also creates a smooth transition with the side contact segments 604, making it easier for the overall fit to conform to the facial contour.

Further, as shown in FIG. 24, the distance between the inner edge 631 and the outer edge 632 is increased in the side contact section 604 and decreases in the direction away from the middle contact section 605. The side contact section 604 starts from the side of the nose and spans the relatively flat area of the face until the position of the tibia, in the low-flat position, it is difficult to fit the face and bear the weight of the device. Therefore, in this embodiment, The distance between the inner edge 631 and the outer edge 632 on the side contact section 604 is first increased and then decreased, and a larger abutment surface 636 can be provided in a relatively flat area of the face, as much as possible. Fitted to the bonding surface 636. Compared with the prior art, the distance between the inner edge 631 and the outer edge 632 changes, on the one hand, the area of the abutment surface 636 can be increased, and on the other hand, the weight of the side contact section 604 can be reduced, so that the whole device More light and thin.

In some embodiments of the present application, as shown in FIG. 26, the face support 6 further includes an inner edge support surface 639 connecting the abutment surface 636 and the auxiliary positioning surface 32; transitioning from the middle contact portion 605 to the side contact portion 604 The width of the edge support surface 639 is gradually increased first and then gradually decreased. The inner edge support surface 639 provided on the face rest 6 is used to establish a joint surface between the inner edge 631 of the face rest 6 and the auxiliary positioning surface 32. In order to obtain a larger face fit area, the transition surface 636 of the face rest 6 transitions from the conforming curve 635 to the inner edge 631, generally causing the inner edge 631 to exceed the edge position below the rear case 3, thus An inner edge support surface 639 is formed between the inner edge 631 and the auxiliary positioning surface 32. In addition, the position where the inner edge support surface 639 has the largest width corresponds to the position at which the side of the nose transitions to the cheek. Therefore, the width from the middle contact section 605 to the inner edge supporting surface 639 of the side contact section 604 is gradually increased first, and then gradually reduced to form a thicker buffer structure at the position of the largest width, reducing the face support 6 being worn. When it is deformed by being squeezed, the problem of the face structure cannot be sufficiently adhered.

In some embodiments of the present application, as shown in FIG. 27, the auxiliary positioning surface 32 is obliquely connected to the main body bonding surface 31 at a position close to the face support 6; the formed housing angle β continuously changes on the rear case 3. The transition from the flange 602 to the side contact section 604 increases the angle β of the housing to 90 degrees. The auxiliary positioning surface 32 has an inclined relationship with the main body abutting surface 31 at a position close to the face support 6 at the center. Such a structure can not only form a smooth inclined curved surface for conveniently setting the face support 6 in the middle position, but also provide a larger optional range for the inclination angle of the fitting surface 636, which is convenient for the entire device to be worn; In a manner, the corresponding width of the auxiliary positioning surface 32 near the face support 6 is increased. Therefore, the front case 1 having a larger area can be connected to block the optics, and the light in the external environment can be prevented from entering the field of view from the position of the face support 6, thereby affecting the viewing effect.

In the above embodiments, not only virtual reality devices but also any head mounted devices, and the head mounted devices include, but are not limited to, virtual reality devices, augmented reality devices, gaming devices, mobile computing devices, and other wearable devices. Computer, etc. It should be noted that the numerical values disclosed in the embodiments of the present application, including the distance ratio, the width ratio, and the thickness ratio, are examples for illustrating the dimensional relationship between the components.

The specific changed value is not described in detail in the application, and can be calculated according to the proportional relationship disclosed in the present application.

As can be seen from the above technical solutions, the present application provides a virtual reality device assembly, including a front case 1, a rear case 3, and a face support 6 disposed on the rear case 3, wherein the face support 6 includes a face conforming to the wearer. The side contact section 604 and the middle contact section 605 in contact with the nose, the front case 1 and the rear case 3 are joined to form a cavity for housing the optical component and the electronic device. In actual use, the fitting inclination angle α, the thickness L, and the distance between the inner edge 631 and the outer edge 632 of the face support 6 are continuously changed according to the facial structure, so that the fitting surface 636 of the face support 6 Fully contact the face, take the weight of the entire virtual reality device from the nose to the face, and increase the contact area, so that the wearer feels comfortable during the wearing process. When the existing virtual reality device is worn for a long time, the wearer will be generated. The problem of discomfort.
