Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a VR device. Background Technology

[0002] With the development of electronic products, new intelligent terminal devices such as Virtual Reality (VR) have developed very rapidly, and they are being used by more and more users and applied to more and more scenarios.

[0003] Current VR devices typically only have a display screen facing the user's eyes. To achieve monitoring purposes or to facilitate device pre-setting, an additional display screen needs to be placed on the outside of the device, that is, on the side that does not face the user's eyes. This is usually the front of the device away from the display screen or the side adjacent to the display screen, which undoubtedly increases the cost of the device significantly. Summary of the Invention

[0004] This application provides a VR device that solves the problem that current VR devices require an additional display screen, which significantly increases the cost of the device.

[0005] This application provides a VR device, which includes a main body, a lens barrel, a display screen, lenses, and a light path steering component, wherein...

[0006] The lens barrel is mounted on the main body, the lens is disposed on the lens barrel, and the display screen is disposed at the end of the lens barrel;

[0007] The display screen includes a first display section and a second display section, wherein the first display section is opposite to the portion of the lens located inside the lens barrel, and the second display section is located outside the lens barrel;

[0008] The light path deflector is disposed on the outside of the lens barrel and is disposed opposite to the second display unit to deflect the emitted light from the second display unit.

[0009] This application discloses a VR device, in which a lens barrel is mounted on a main body, a lens is disposed on the lens barrel, and a display screen is mounted on the end of the lens barrel. The first display portion of the display screen is opposite to the portion of the lens located inside the lens barrel, so that the light emitted from the first display portion can be transmitted through the lens to the user's eyes, allowing the user to view the preset pattern displayed on the display screen. At the same time, the second display portion of the display screen is located outside the lens barrel, and is disposed opposite to the second display portion by a light path deflector disposed outside the lens barrel. The light path deflector can provide a deflection effect on the propagation direction of the image of the second display portion, so that the light emitted from the second display portion can be directed in a different direction than the light emitted from the first display portion. This makes it convenient for users who are not wearing the VR device to view the content displayed on the second display portion, facilitating the monitoring or pre-setting of the VR device. Furthermore, it eliminates the need for a separate additional display screen for the VR device, thereby reducing costs to a certain extent. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details a VR device provided in this application through specific embodiments and application scenarios.

[0028] like Figures 1-7 As shown in the embodiment of this application, a VR device can specifically be VR glasses, but it can also be other forms of devices such as a hat-shaped structure, which are not limited herein. The VR device includes a main body 100, a lens barrel 200, a display screen 300, lenses 400, and an optical path steering component 500.

[0029] The main body 100 serves as the basic structure of the VR device, acting as the connection base between other components, thus forming a unified whole. In the case of VR glasses, the main body 100 may specifically include structures such as temples and frames.

[0030] The lens barrel 200 is used to confine the light emitted from the display screen 300 in the VR device, making it easier for the light to focus on the user's eyes and enhancing the realism of the content displayed by the VR device. Both the body 100 and the lens barrel 200 can be made of rigid materials such as plastic or metal, and this article does not limit their dimensions or other parameters.

[0031] During assembly, the lens barrel 200 is mounted on the main body 100, the lens 400 is disposed on the lens barrel 200, and the display screen 300 is disposed at the end of the lens barrel 200. This ensures that light emitted from the portion of the display screen 300 facing the inner side of the lens barrel 200 can propagate along the internal space of the lens barrel 200 to the lens 400, and then, through the optical action of the lens 400, enter the user's eyes, allowing the user to obtain the corresponding image. Specifically, the main body 100 and the lens barrel 200, the lens 400 and the lens barrel 200, and the display screen 300 and the lens barrel 200 can all be connected using connectors, or other methods such as adhesive can be used to form an assembly relationship between the corresponding two components. In addition, to improve the sealing between the display screen 300 and the lens barrel 200 and ensure that the reliability of the display effect remains relatively high, a sealing ring 700 can also be provided between the display screen 300 and the lens barrel 200.

[0032] Lens 400 is a device used in VR devices to perform optical processing on the image displayed on display screen 300. It may include a convex lens. Of course, there may be one or more lenses 400, and the type and parameters of multiple lenses 400 can be selected according to the actual situation to maximize the realism of the image seen by the user.

[0033] The display screen 300 is a device used in VR devices to display preset images. Generally, due to user habits, VR devices typically have two sets of corresponding lens barrels 200 and lenses 400. In this case, the number of display screens 300 can be one, corresponding to both lens barrels 200 simultaneously, or the number of display screens 300 can be two, each corresponding to one of the two lens barrels 200. This article does not impose any restrictions on this. However, it should be noted that due to the user's field of view and the optical effect of the lenses 400, the lenses 400 are usually circular, which in turn makes the cross-section of the lens barrel 200 usually circular or nearly circular. In order to reduce manufacturing costs and improve the overall display effect of the display screen 300, the display screen 300 is usually not circular; it is generally rectangular or polygonal. This inevitably leads to some display area of ​​the display screen 300 being wasted, which undoubtedly results in lower effectiveness of the costs already incurred.

[0034] Based on the above, in detail, the display screen 300 includes a first display section 310 and a second display section 320. Correspondingly, the first display section 310 and the second display section 320 are connected to each other, making the display screen 300 a whole. Specifically, the first display section 310 and the second display section 320 can be formed together, that is, they are two artificially divided areas on the same display screen 300, and in terms of physical structure, there is no obvious boundary between them.

[0035] In this embodiment, the first display unit 310 is opposite to the portion of the lens located inside the lens barrel 200, that is, the first display unit 310 corresponds to the inner side of the lens barrel 200, while the second display unit 320 is located on the outer side of the lens barrel 200. In other words, during the use of the VR device disclosed in this application embodiment, the image displayed by the first display unit 310 can be transmitted to the user's eyes through the internal space of the lens barrel 200. Although the second display unit 320 can also display images along with the display area, since it does not correspond to the internal space of the lens barrel 200, the image displayed by the second display unit 320 cannot be seen by the user through the internal space of the lens barrel 200.

[0036] For example, the display screen 300 can be square or rectangular, mounted at one end of the lens barrel 200, and its central area corresponds to the internal space of the lens barrel 200. That is, the first display section 310 of the display screen 300 corresponds to the inner side of the lens barrel 200. However, the outer edge area of ​​the display screen 300, located around the central area, cannot correspond to the internal space of the lens barrel 200, so the image displayed in the outer edge area cannot be seen by the user through the lens barrel 200. The aforementioned outer edge area is the second display section 320. Of course, the display screen 300 can also have other structural forms, but for the sake of brevity, they will not be described in detail here.

[0037] In order to effectively utilize the display image in the second display section 320 of the display screen 300 that cannot be seen by the user through the internal space of the lens barrel 200, as described above, in this embodiment of the application, the VR device includes a light path steering component 500, such as... Figure 1 As shown, the light path deflector 500 is disposed on the outer side of the lens barrel 200, and is disposed opposite to the second display unit 320, so as to redirect the propagation direction of the emitted light from the second display unit 320. Specifically, the propagation direction of the emitted light from the second display unit 320 can be redirected to the side of the display screen 300 opposite to the display side of the first display unit 310, or it can be redirected to the side of the display screen 300 adjacent to the display side of the first display unit.

[0038] In detail, both the first display unit 310 and the second display unit 320 have an initial display direction. As described above, since they can be different areas on the same display screen 300, their display directions are the same when no other device is used. Specifically, their display directions are the directions they face toward the eyes of the user wearing the device. However, due to the action of the light path steering member 500 disposed opposite to the second display unit 320, the light path steering member 500 can provide the second display unit 320 with the ability to change the direction of light propagation, so that the final display direction of the second display unit 320 can be different from the display direction of the first display unit 310.

[0039] For example, the light path steering member 500 can be a reflector, and by making the reflector at a 45° angle relative to the display surface of the second display unit 320, the light path steering member 500 can project the display image of the second display unit 320 onto the side of the second display unit 320, so that users who are not wearing VR devices can also see the content displayed on the display screen 300 and perform tasks such as monitoring or presetting the VR device.

[0040] This application discloses a VR device, in which a lens barrel 200 is mounted on a body 100, a lens 400 is disposed on the lens barrel 200, and a display screen 300 is mounted on the end of the lens barrel 200. The first display portion 310 of the display screen 300 is opposite to the portion of the lens 400 located inside the lens barrel 200, allowing light emitted from the first display portion 310 to be transmitted through the lens 400 to the user's eyes, enabling the user to view a preset pattern displayed on the display screen 300. Simultaneously, the second display portion 320 of the display screen 300 is located outside the lens barrel 200 and utilizes the portion disposed on the lens barrel... The light path steering member 500 on the outer side of 200 is disposed opposite to the second display unit 320, so that the light path steering member 500 can provide a steering effect on the propagation direction of the image of the second display unit 320, thereby enabling the emitted light of the second display unit 320 to be directed in a different direction than the emitted light of the first display unit 310. This makes it easier for users who are not wearing the VR device to view the content displayed on the second display unit 320, and facilitates the supervision or pre-setting of the VR device. Moreover, there is no need to equip the VR device with an additional display screen 300, which can reduce costs to a certain extent.

[0041] As described above, in the VR device disclosed in this application embodiment, the light path steering member 500 can specifically be a reflector, and the reflector is used to change the propagation direction of the emitted light from the second display unit 320. More specifically, in the process of changing the propagation direction of the emitted light from the second display unit 320 using the light path steering member 500, the specific type or structure of the light path steering member 500 can be designed so that the emitted light from the second display unit 320, after being turned by the light path steering member, is deflected in a direction away from the display side of the display screen, and the deflection angle is α, which can be 90°≤α≤180°. In layman's terms, taking the direction of the emitted light from the first display unit 310 as the back of the VR device as an example, the light path diverter can redirect the emitted light from the second display unit to the side of the VR device, that is, the emitted light from the second display unit 320 is deflected by an angle of 90°; or, the light path diverter can redirect the emitted light from the second display unit to the front of the VR device, that is, the emitted light from the second display unit 320 is deflected by an angle of 180°. Of course, the light path diverter can also redirect the emitted light from the second display unit to the area between the side and the front of the VR device, which makes it relatively more convenient for users who are not wearing the device to view the displayed content of the second display unit 320.

[0042] In another embodiment of this application, the light path steering component 500 includes a first prism 510, which includes an incident light surface 511a, a first tilted reflecting surface 511b, a second tilted reflecting surface 513a, and an emitting light surface. The incident light surface 511a is disposed opposite to the second display unit 320 to ensure that light emitted from the second display unit 320 can propagate through the incident light surface 511a into the first prism 510. Furthermore, the incident light surface 511a can be disposed parallel to the display surface of the second display unit 320, which improves both the reliability of light incident into the first prism 510 and the display effect of the light incident into the first prism 510. Simultaneously, the first tilted reflecting surface 511b and the second tilted reflecting surface 513a can reflect light incident from the incident light surface 511a back to the other side of the incident light surface 511a, thereby changing the initial propagation direction of the light. In detail, the emitted light from the second display unit 320 can pass through the incident light surface 511a and be incident on the first tilted reflective surface 511b of the first prism 510. Then, it is reflected sequentially by the first tilted reflective surface 511b and the second tilted reflective surface 513a, and then emitted from the light-emitting surface of the first prism 510 to the outside of the first prism 510.

[0043] Specifically, the first tilted reflective surface 511b is tilted opposite to the incident light surface 511a to ensure that it can receive light incident from the incident light surface 511a and reflect the received light towards the second tilted reflective surface 513a. Similarly, the second tilted reflective surface 513a is tilted opposite to the first tilted reflective surface 511b to ensure that it can receive light reflected from the first tilted reflective surface 511b and reflect the received light towards the emitting light surface, thereby changing the propagation direction of the light emitted from the second display unit 320. Both the first tilted reflective surface 511b and the second tilted reflective surface 513a can be planar, and their positions and relative tilt angles with the incident light surface 511a can be determined according to the required reflection angle of the first prism 510.

[0044] Furthermore, when the specific parameters of the first tilted reflective surface 511b and the second tilted reflective surface 513a are different, the propagation direction of the emitted light from the second display unit 320 can also be different. More specifically, the light-emitting surface and the light-receiving surface 511a can be arranged on opposite sides, that is, the angle by which the propagation direction of the emitted light from the second display unit 320 is deflected is not equal to 180°.

[0045] In another embodiment of this application, if the area of ​​the light-incident surface 511a is sufficient, the light reflected from the second tilted reflective surface 513a can pass back through the light-incident surface 511a and exit onto the side of the light-incident surface 511a facing the second display unit 120. In this case, the propagation direction of the light emitted from the second display unit 320 is deflected by an angle equal to 180°. In the above embodiments of this application, the emission direction of the first prism 510 is parallel to its incident direction, which allows the user to view the display content of the VR device from the front of the VR device, that is, from the side opposite to the display surface of the first display unit 310 in the display screen 300. This can greatly reduce the difficulty for users who are not wearing VR devices to view the images displayed on the display screen 300 in the VR device.

[0046] Based on the above embodiments, such as Figure 9 As shown, the first prism 510 can specifically be a triangular prism. By aligning a portion of one side surface of the first prism 510 with the second display unit 320, and by designing the parameters of the first prism 510, it can be ensured that the other portion of that side surface of the first prism 510 can serve as a light-emitting surface, so that the light displayed by the second display unit 320 is incident and emitted from different areas of the same side surface of the first prism 510 respectively.

[0047] In another embodiment of this application, in order to reduce the space occupied by the first prism 510 and to reduce the design difficulty of the first prism 510, such as Figure 1 The first prism 510 can be an equilateral trapezoidal structure, which can simplify the propagation process of light in the first prism 510 and allow the light to be turned 180° using the first prism 510.

[0048] In the above embodiments, both the first tilted reflective surface 511b and the second tilted reflective surface 513a can be planar structures. Considering that the area of ​​the second display unit 320 is usually relatively small, and therefore the image it can display is also relatively small, in order to enable the user to obtain a clearer image displayed by the second display unit 320, in another embodiment of this application, the second tilted reflective surface 513a is a convex surface. This enables the second tilted reflective surface 513a to have the ability to magnify the image, thereby enabling the user to obtain a clearer display image, and ensuring that the second tilted reflective surface 513a can receive the light emitted from the first tilted reflective surface 511b more completely.

[0049] To ensure that light can be properly reflected on the second inclined reflecting surface 513a, which has a convex structure, specifically, as follows: Figure 8 As shown, the first prism 510 includes a light-incident section 511, a connecting section 512, and a light-emitting section 513. The light-incident section 511 and the light-emitting section 513 are spaced apart and fixedly connected by the connecting section 512. The light-incident section 511 has a light-incident surface 511a and a first inclined reflective surface 511b. The light-incident surface 511a faces the second display section 320. The first inclined reflective surface 511b is adjacent to the light-incident surface 511a and is located on the side of the light-incident section 511 away from the light-emitting section 513. The light-emitting section 513 has a second inclined reflective surface 513a. The second inclined reflective surface 513a is located on the side of the light-emitting section 513 facing the light-incident section 511 and is opposite to the first inclined reflective surface 511b to receive the light emitted from the first inclined reflective surface 511b. Since the light-emitting section 513 and the light-incident section 511 are spaced apart, in this embodiment, the second inclined reflective surface 513a is the light-emitting surface. Of course, by designing the parameters of the first tilted reflective surface 511b and the second tilted reflective surface 513a, it is possible to prevent light emitted from the second tilted reflective surface 513a from re-entering the light-receiving part 511, thereby ensuring that the image obtained by the user from the second display part 320 has relatively better clarity.

[0050] To further improve the stability of the images obtained by the user from the second display unit 320, in this embodiment of the application, the VR device may further include an image receiver 600, the image receiver 600 being opposite to the light-emitting surface of the light path deflector 500, and the emitted light from the second display unit 320 being deflected by the light path deflector 500 and then projected onto the image receiver 600 for display.

[0051] Specifically, the image receiver 600 is a semi-transparent structural component, and the image receiver 600 can be made of frosted material. That is, the image receiver 600 can be formed of a semi-transparent frosted material, so as to ensure that the user located on one side of the image receiver 600 can obtain the image represented by the light projected from the other side of the image receiver 600, while utilizing the diffuse reflection effect of the frosted material to improve the user's viewing experience.

[0052] When the image receiver 600 is installed, it can be placed on the side of the display screen 300 away from its display side, and the light-incident surface of the light path steering member 500 can be located on the display side of the display screen, so that users who are not wearing the device can use the image receiver 600 to view the display content of the display screen 300 from the side away from the display side of the display screen 300.

[0053] Specifically, the image receiver 600 can be a plate-shaped structure, the size of which corresponds to the size of the image projected by the light path diverter 500, ensuring that it can properly receive the image projected by the light path diverter 500. The image receiver 600 can be fixed to the main body 100 by adhesive or screws and other connectors, so that the image receiver 600 is located on the side of the display screen 300 away from its display side, and the image receiver 600 is correspondingly set with the light path diverter 500. On the one hand, this facilitates the light path diverter 500 to project the image onto the image receiver 600, so that the image receiver 600 can receive the light reflected by the light path diverter 500. On the other hand, it allows users who are in front of the VR device and are not wearing the VR device to view the content displayed on the second display section 320 of the display screen 300 through the image receiver 600.

[0054] As described above, VR devices typically have two sets of corresponding lens barrels 200 and lenses 400, positioned to correspond to the user's eyes. Based on this, the two lens barrels 200 can be spaced apart to differentiate the images seen by the user's two eyes. Correspondingly, each of the two lens barrels 200 can be equipped with a separate display screen 300, or the two lens barrels 200 can be used together with the same relatively large display screen 300. Therefore, at least one optical path steering element 500 can be provided on the side of each lens barrel 200 that is close to each other. This further improves the utilization rate of the area of ​​the display screen 300 that cannot be directly viewed by the user using the VR device (i.e., the second display section 320), and increases the display area that users not wearing VR devices can view. This further improves monitoring efficiency and accuracy, and also facilitates user pre-setting of the VR device.

[0055] Furthermore, in the above embodiment, each light path deflector 500 provided on the side of the two lens barrels 200 that are close to each other can be opposite to the image receiver 600, ensuring that the light emitted by each light path deflector 500 can be projected onto the image receiver 600, making it convenient for users who are not wearing VR devices to view them at the same time.

[0056] As can be seen from the above embodiments, due to the limitations of the conventional shape and structure of the display screen 300 and the lens barrel 200, in the VR device disclosed in this application embodiment, the light path steering component 500 can effectively utilize the display screen 300 that cannot be directly viewed by the user wearing the device. In order to make the overall structure of the VR device more compact, further reduce the overall space occupied by the VR device, and reduce the overall size of the VR device, the light-incident surface of the light path steering component 500 disclosed in the above embodiments can be made to abut against the second display unit, that is, the two are opposite and in contact. This can also prevent light leakage from the second display unit 320, and prevent dust and other particles from entering between the light path steering component 500 and the second display unit 320, thereby improving their service life.

[0057] Meanwhile, during the design of the VR device's lens barrel 200, a chamfer can be provided at the end of the lens barrel 200 closest to the display screen 300, thereby creating a gap between the lens barrel 200 and the display screen 300, or in other words, between the lens barrel 200 and the second display unit 320. Figure 6 As shown, the cross-sectional shape of the gap is generally triangular, and by sandwiching at least a portion of the light path steering member 500 within the gap between the outer side of the lens barrel 200 and the second display section 320, the effective utilization rate of the second display section 320 in the display screen 300 can be further increased. Specifically, during the process of forming the chamfer at the end of the lens barrel 200, the shape of the chamfer can be made to fit and match the shape of the first inclined reflective surface 511b in the light path steering member 500 as closely as possible, so as to further improve the space utilization rate of the VR device.

[0058] Correspondingly, when there are two lens barrels 200, the light path steering component 500 can be placed in the area where the two lens barrels 200 are close to each other. Since both lens barrels 200 are provided with the above-mentioned chamfers and both lens barrels 200 are correspondingly equipped with light path steering components 500, the part where the first inclined reflective surface 511b of each of the two light path steering components 500 is located can be embedded in the chamfered area of ​​the two lens barrels respectively, thereby further improving the space utilization of the VR device and making the integration between the light path steering component 500 and other components such as lens barrels 200 in the VR device better, and greatly reducing the abruptness of the light path steering component 500 in the VR device.

[0059] As described above, in the above embodiments, the first prism 510 can provide a deflection effect of about 180° (such as the range of 150° to 210°) on the light emitted from the second display unit 320. In another embodiment of this application, such as... Figure 9 As shown, the light path deflector 500 may include a second prism 520, which includes an incident light surface 521, a first reflecting surface 522, and an exiting light surface 523. The incident light surface 521 is disposed opposite to the second display unit 320 to ensure that light emitted from the second display unit 320 can pass through the incident light surface 521 and enter the second prism 520. The first reflecting surface 522 receives the light incident from the incident light surface 521 and reflects it to the exiting light surface 523. That is, the light emitted from the second display unit 320 can pass through the incident light surface 521, enter the first reflecting surface 522, be reflected and deflected by the first reflecting surface 522, and then exit the second prism 520 from the exiting light surface 523. Specifically, the first reflecting surface 522 can be a planar structure, which is correspondingly arranged with the light-incident surface 521 and the light-exiting surface 523, thereby ensuring that the first reflecting surface 522 can serve as a medium between the light-incident surface 521 and the light-exiting surface 523 and provide the function of reflecting light.

[0060] Accordingly, by setting parameters such as the tilt angle of the first reflective surface 522, it can be ensured that the light reflected by the first reflective surface 522 can enter the light-emitting surface 523, and that the light can exit from the light-emitting surface 523 to other sides adjacent to the display side of the second display unit 320. Specifically, it can be any one of the left, right, upper, or lower sides of the second display unit 320, thereby ensuring that users who are not wearing VR devices can view the display content of the VR device's screen 300 from the side of the VR device, that is, the side located between the front and back.

[0061] As described above, the first reflective surface 522 is obliquely opposite to the light-incident surface 521, and the first reflective surface 522 is also obliquely opposite to the light-emitting surface 523. Based on this, optionally, the light-incident surface 521 and the light-emitting surface 523 are symmetrically arranged relative to the first reflective surface 522 of the planar structure, and the included angle between them can be 40°, 60°, or 80°, etc. In another embodiment of this application, the emission direction of the second prism 520 is perpendicular to its incident direction. That is, in the second prism 520, the included angle between the light-incident surface 521 and the first reflective surface 522 is 45°, and the included angle between the reflective surface and the first reflective surface 522 is also 45°. This allows users who are not wearing VR devices to view the display content of the VR device's screen 300 from the left or right (or top or bottom) side of the VR device, further reducing the difficulty for users who are not wearing VR devices to view the display content of the screen 300, and improving the clarity of the display content of the second display unit 320 obtained by the user.

[0062] As described above, the VR device can be provided with two sets of corresponding lens barrels 200 and lenses 400. Based on the above embodiment, at least one optical path steering element 500 can also be provided on the side of each of the two mutually spaced lens barrels 200 that is far apart from each other. This can provide users who are not wearing VR devices with a variety of viewing angles of the content displayed on the display screen 300 in the VR device, further reducing the difficulty for users to view the content displayed on the display screen 300 and improving the ease of use of the VR device.

[0063] Of course, in a VR device equipped with a second prism 520, the above-mentioned image receiver 600 can also be provided, and the position of the image receiver 600 is aligned with the second prism 520 to ensure that the image receiver 600 can normally receive the light emitted by the second prism 520.

[0064] Based on the VR device comprising two spaced-apart lens barrels 200 disclosed in the above embodiments, optionally, each lens barrel 200 may have a display screen 300 at its end, and the second display portion 320 of each display screen 300, which cooperates with the light path steering member 500, may be located on the side of the corresponding lens barrel 200 away from the other lens barrel 200, that is, both second display portions 320 are located on the outer side of the lens barrel 200. In this case, at least one light path steering member 500 may be provided on the side of the two lens barrels that are away from each other, and the emitted light from the second display portion 320 of each of the two display screens 300 may be directed to the side of the lens barrel 200 by the corresponding light path steering member, specifically, one lens barrel 200 is away from the outer side of the other lens barrel 200, thereby facilitating the user not wearing the VR device to obtain the display content of the display screen 300 from the outside of the device. Of course, in this technical solution, at least one image receiver 600 may be provided for each of the two light path steering members 500.

[0065] Alternatively, the second display units 320 in each display screen 300 that cooperate with the light path steering element 500 are all located on the side of the corresponding lens barrel 200 closest to the other lens barrel 200, that is, both second display units 320 are located between the two lens barrels 200. In this case, at least one light path steering element 500 can be provided on the side of the two lens barrels that are close to each other, and the emitted light from the second display units 320 of each of the two display screens 300 can be redirected by the corresponding light path steering element to the side of the display screen 300 away from its display side, thereby making it easier for users who are not wearing VR devices to obtain the display content of the display screen 300 from the front of the device. Of course, in this technical solution, the same image receiver 600 can be used to cooperate with both light path steering elements 500, reducing the complexity of component assembly.

[0066] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
