[0068] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0069] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an,” “a,” or “the,” and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. The terms “including,” “comprising,” or “containing,” and similar terms mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. The terms “connected,” “linked,” or similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” and “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0070] In this disclosure, "multiple or several" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0071] In related technologies, traditional VR optical engines integrate the optical display module and the driving module together, placing them in the VR headset section. This makes the VR headset module relatively thick and heavy, affecting the user's wearing experience. At the same time, multiple data cables located on the VR optical engine base connect to the VR headset module in the VR headset module, resulting in complex wiring and hindering the achievement of a thinner and lighter design for the support module.

[0072] In view of this, the present disclosure provides a VR optical engine that substantially eliminates one or more problems caused by the limitations and defects of related technologies. Specifically, the VR optical engine in the present disclosure includes a base, a drive module disposed within a base receiving cavity of the base, a VR headset module, a support module, and a connection module; the support module is connected to the base and is used to support the VR headset module; the VR headset module includes a VR display module, and the drive module is electrically connected to the VR display module through the connection module.

[0073] The VR optical engine provided in this disclosure separates the VR display module and the driving module. Specifically, the driving module is housed within the base cavity and electrically connected to the VR display module located in the VR headset module via a connecting module. Compared to the traditional design where the VR headset module integrates the optical display module and the driving module, this disclosure achieves a thinner and lighter VR headset module. Simultaneously, since the chip (IC) in the driving module is the main heat source, fixing the driving module within the base cavity and separating it from the VR headset module facilitates independent heat dissipation for the IC and improves system stability. Furthermore, compared to the traditional design where multiple data cables pass through the support module to connect to the driving module in the VR headset module, this disclosure utilizes a connecting module to reduce the number of cables passing through the support module, effectively reducing the size of the support module and achieving a thinner and lighter design.

[0074] The specific structure of the VR optical engine provided in the embodiments of this disclosure will be described in detail below.

Figure 2 An isometric view of another exemplary VR optical engine provided in this embodiment of the disclosure. Figure 3 An exploded view of the bracket module 3 provided in the embodiments of this disclosure, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, the VR optical engine includes a base 1, a drive module 11 disposed in the base cavity of the base 1, a VR head-mounted display module 2, a support module 3, and a connecting module 4; the support module 3 is connected to the base 1 and is used to support the VR head-mounted display module 2.

[0076] The VR headset module 2 includes a VR display module 2-5, and the drive module 1-1 is electrically connected to the VR display module 2-5 through the connection module 4.

[0077] For example, the connecting module 4 can pass through the support cavity formed by the bracket module 3 to achieve electrical connection between the drive module 1-1 and the VR display module 2-5. Alternatively, for example, the bracket module 3 can be used not only as a support for the VR headset module 2, but also as a support for the connecting module 4.

Figure 12 This is a cross-sectional view of the VR optical engine provided in an embodiment of this disclosure. Figure 13 This is a schematic diagram of a connection module provided in an embodiment of this disclosure.

[0079] In some embodiments, such as Figure 4 As shown, the VR headset module 2 also includes the VR main housing 2-7. (As...) Figure 3 , Figure 6 , Figure 7 , Figure 12 and Figure 13 As shown, the connection module 4 includes a first conductive component 4-1, a second conductive component 4-2 and a third conductive component 4-3 that are electrically connected to both ends of the first conductive component 4-1 respectively; the first conductive component 4-1 is disposed in the support cavity formed by the bracket module 3; the second conductive component 4-2 passes through the first opening 2-7-3 on the VR main housing 2-7 and is electrically connected to the VR display module 2-5; the third conductive component 4-3 passes through the second opening 1-2-1 on the base 1 and is electrically connected to the drive module 1-1.

[0080] For example, the first conductive component 4-1 is located in the support cavity, which can be a prefabricated signal line. This greatly avoids the need for multiple data lines 1-4 connected to the drive module 1-1 to pass through the bracket module 3, reduces the number of wires passing through the bracket module 3, effectively reduces the volume of the bracket module 3, and achieves the thinning of the bracket module 3.

[0081] For example, the second conductive component 4-2 and the third conductive component 4-3 may be selected as flexible printed circuit boards (FPCs) as conductive components for electrical connection to the VR display module 2-5 and the drive module 1-1.

[0082] For example, the first conductive component 4-1, the second conductive component 4-2, and the third conductive component 4-3 are integrally connected. The first conductive component 4-1 can be a prefabricated signal line, and the outer layer of the line can be covered with an insulating material, such as shielding material and soft adhesive material. The materials for the second conductive component 4-2 and the third conductive component 4-3 can both be FPC materials.

[0083] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the VR display module 2-5 includes a left eye optical unit 2-5-1, a first connecting sub-assembly 2-5-11 electrically connected to the left eye optical unit 2-5-1, a right eye optical unit 2-5-2, and a second connecting sub-assembly 2-5-21 electrically connected to the right eye optical unit 2-5-2; the second conductive component 4-2 includes a first conductive part 4-2-1, a second conductive part 4-2-2 and a third conductive part 4-2-3 electrically connected to both ends of the first conductive part 4-2-1, a third connecting sub-assembly 4-2-4 fixed on the second conductive part 4-2-2, and a fourth connecting sub-assembly 4-2-5 fixed on the third conductive part 4-2-3; the first connecting sub-assembly 2-5-11 is electrically connected to the third connecting sub-assembly 4-2-4; the second connecting sub-assembly 2-5-21 is electrically connected to the fourth connecting sub-assembly 4-2-5.

[0084] The left and right eye optical modules 2-5-1 and 2-5-2 are core components of the VR display module 2-5, used to form virtual images. The left and right eye optical modules 2-5-1 and 2-5-2 mainly consist of optical lenses, lens barrel structures, and display modules.

[0085] For example, the first connecting sub-assembly 2-5-11, the second connecting sub-assembly 2-5-21, the third connecting sub-assembly 4-2-4, and the fourth connecting sub-assembly 4-2-5 can all be connectors, such as board-to-board (BTB) connectors, wherein the first connecting sub-assembly 2-5-11 is electrically connected to the third connecting sub-assembly 4-2-4, the first connecting sub-assembly 2-5-11 can be a BTB female connector, and the third connecting sub-assembly 4-2-4 can be a BTB male connector, and the two are mated together and locked in place with screws. Figure 6 (The screw is not shown; the corresponding threaded hole A is shown.) The second connecting sub-assembly 2-5-21 is electrically connected to the fourth connecting sub-assembly 4-2-5. The second connecting sub-assembly 2-5-21 can be a BTB female connector, and the fourth connecting sub-assembly 4-2-5 can be a BTB male connector. The two are inserted into each other and locked in place with screws. Figure 6 The screw is not shown, but the corresponding threaded hole B is shown, thereby achieving electrical connection between the second conductive part 4-2-2 (FPC) and the display module in the left eye optical engine 2-5-1, and electrical connection between the third conductive part 4-2-3 (FPC) and the display module in the right eye optical engine 2-5-2. This embodiment utilizes the connection stability of the board-to-board (BTB) connector to improve the signal transmission stability between the FPC board and the VR display module 2-5 from the hardware itself.

[0086] For example, the first conductive part 4-2-1, the second conductive part 4-2-2, and the third conductive part 4-2-3 can be an integrally connected structure. The first conductive part 4-2-1 can be a wire connecting the second conductive part 4-2-2 (FPC) and the third conductive part 4-2-3 (FPC). The length of this wire is greater than the length of the line connecting the center points of the left and right optical transducers 2-5-1 and 2-5-2, facilitating subsequent interpupillary distance adjustment to accommodate individuals with different interpupillary distances.

[0087] In some embodiments, such as Figure 6 As shown, taking the first connecting sub-assembly 2-5-11 and the second connecting sub-assembly 2-5-21 as BTB connectors, the VR display module 2-5 also includes a first limiting adhesive frame 2-5-12 sleeved on the first connecting sub-assembly 2-5-11 and a second limiting adhesive frame 2-5-22 sleeved on the second connecting sub-assembly 2-5-21.

[0088] In this embodiment, a bias-limiting rubber frame is used on the outside of the BTB female connector for bias-limiting fixation, which can effectively prevent the connector from tilting and improve the stability of the connector signal transmission.

[0089] In some embodiments, such as Figure 6As shown, the VR display module 2-5 also includes a first fixing component that is fixedly connected to the left eye optical machine 2-5-1 and a second fixing component that is fixedly connected to the right eye optical machine 2-5-2; the second conductive part 4-2-2 is fixed to the left eye optical machine 2-5-1 through the first fixing component, and the third conductive part 4-2-3 is fixed to the right eye optical machine 2-5-2 through the second fixing component.

[0090] like Figure 5 and Figure 6 As shown, the first fixing component may be, for example, a first wire clamp 2-5-3, which includes a first clamping piece 2-5-31 and a second clamping piece; the second fixing component may be, for example, a second wire clamp 2-5-4, which includes a third clamping piece 2-5-41 and a fourth clamping piece 2-5-42. The second conductive part 4-2-2 is divided into a connection area for the third connecting sub-assembly 4-2-4 and a clamping area for self-clamping and fixing; the first clamping piece 2-5-31 is fixed to the left eyepiece 2-5-1, and the second conductive part 4-2-2 is disposed between the first clamping piece 2-5-31 and the second clamping piece. The first clamping piece 2-5-31 and the second clamping piece together clamp the portion of the second conductive part 4-2-2 located in the clamping area and are fixed by screws. Figure 6 The screw is not shown, but the corresponding threaded hole C is shown. Similarly, the third conductive part 4-2-3 is divided into a connection area for the fourth connecting sub-assembly 4-2-5 and a clamping area for self-clamping and fixing; the third clamping piece 2-5-41 is fixed to the right ophthalmic machine 2-5-2, and the third conductive part 4-2-3 is disposed between the third clamping piece 2-5-41 and the fourth clamping piece 2-5-42. The third clamping piece 2-5-41 and the fourth clamping piece 2-5-42 together clamp the portion of the third conductive part 4-2-3 located in the clamping area and are locked and fixed by screws. Figure 6 The screw is not shown; the threaded hole D corresponding to the screw is shown.

[0091] In this embodiment, in conjunction with the above embodiments, a wire clamp is further used to fix the first conductive component 4-1. The large-area contact between the wire clamp and the conductive parts (the first conductive part 4-2-1 and the second conductive part 4-2-2) allows for locking under force. Under the same force, the larger the area, the lower the pressure. Therefore, the wire clamp fixing method used in this embodiment can effectively prevent the welding part of the first conductive component 4-1 from opening during the movement of the VR optical engine (such as oscillation during use or interpupillary distance adjustment), ensuring the stability of the signal transmission of the overall connection module 4.

[0092] Of course, provided that the signal transmission is stable during the movement of the VR optical engine, the first fixing component and the second fixing component may also use other fixing methods to fix the first conductive component 4-1, and this embodiment does not limit this.

[0093] In some embodiments, the VR display module 2-5 further includes an interpupillary distance adjustment component disposed on the VR display module 2-5 for performing interpupillary distance adjustment.

[0094] For example, the interpupillary distance adjustment component can achieve interpupillary distance adjustment by using a gear 2-5-53 rack and pinion meshing method. For instance, by pulling the left eyepiece 2-5-1 and / or the right eyepiece 2-5-2, the linear distance between the left eyepiece 2-5-1 and the right eyepiece 2-5-2 can be increased or decreased through the gear 2-5-53 rack and pinion meshing transmission, thereby adapting to people with different interpupillary distances.

[0095] Specifically, this embodiment of the disclosure takes the interpupillary distance adjustment component using a gear 2-5-53 rack and pinion engagement as an example to achieve interpupillary distance adjustment. Figure 6 As shown, the VR display module 2-5 also includes a first rack 2-5-51 fixedly connected to the left optical transducer 2-5-1, a second rack 2-5-52 fixedly connected to the right optical transducer 2-5-2, and a gear 2-5-53 meshing with the first rack 2-5-51 and the second rack 2-5-52.

[0096] Of course, the interpupillary distance adjustment component can also be other transmission components. For example, the interpupillary distance adjustment component can also use a guide rail slider to achieve interpupillary distance adjustment. For example, by pulling the left eyepiece 2-5-1 and / or the right eyepiece 2-5-2, the linear distance between the left eyepiece 2-5-1 and the right eyepiece 2-5-2 can be increased or decreased through the sliding (or rolling) transmission of the guide rail slider, thereby adapting to people with different interpupillary distances.

[0097] In some embodiments, such as Figure 7 and Figure 13 As shown, the drive module 1-1 includes a drive circuit board, a fifth connection sub-assembly and a sixth connection sub-assembly electrically connected to the drive circuit board; the third conductive component 4-3 includes a fourth conductive part 4-3-1, a fifth conductive part 4-3-2 and a sixth conductive part 4-3-3 electrically connected to both ends of the fourth conductive part 4-3-1, a seventh connection sub-assembly fixed on the fifth conductive part 4-3-2, and an eighth connection sub-assembly fixed on the sixth conductive part 4-3-3; the fifth connection sub-assembly and the seventh connection sub-assembly are electrically connected; the sixth connection sub-assembly and the eighth connection sub-assembly are electrically connected.

[0098] The driver circuit board is a core component of the driver module 1-1, mainly containing electronic components such as driver chips and storage chips. It is used to send signals to drive the display images of the left eye optical transducer 2-5-1 and the right eye optical transducer 2-5-2. The driver circuit board can be, for example, a driver PCB board. The driver PCB board is fixedly locked onto the base 1, and the heat generated by the driver PCB board is conducted to the base 1, which is beneficial for chip (IC) heat dissipation and system stability.

[0099] For example, the fifth, sixth, seventh, and eighth connecting sub-assemblies can all be connectors, such as board-to-board (BTB) connectors. The fifth and seventh connecting sub-assemblies are electrically connected and secured with screws; the sixth and eighth connecting sub-assemblies are also electrically connected and secured with screws, thereby achieving electrical connection between the fifth conductive part 4-3-2 (FPC) and the sixth conductive part 4-3-3 (FPC) and the driving PCB board. This embodiment utilizes the connection stability of the board-to-board (BTB) connector to improve the stability of signal transmission between the driving PCB board and the FPC board from the hardware perspective.

[0100] In some embodiments, the drive module 1-1 further includes a third limiting adhesive frame sleeved on the fifth connecting sub-assembly and a fourth limiting adhesive frame sleeved on the sixth connecting sub-assembly.

[0101] In this embodiment, a bias-limiting rubber frame is used on the outside of the BTB female connector for bias-limiting fixation, which can effectively prevent the connector from tilting and improve the stability of the connector signal transmission.

[0102] In some embodiments, such as Figure 3 and Figure 8 As shown, the bracket module 3 includes a bracket main housing 3-1, a first snap-fit ​​assembly 3-2, and a bracket rear cover 3-3; the bracket main housing 3-1 and the bracket rear cover 3-3 are snapped together by the first snap-fit ​​assembly 3-2, and the bracket main housing 3-1 and the bracket rear cover 3-3 form a support and receiving cavity.

[0103] For example, such as Figure 8 As shown, the first snap-fit ​​assembly 3-2 has a first protrusion 3-2-1 and a second protrusion 3-2-2; the main housing 3-1 of the bracket has a first recess that fits tightly with the first protrusion 3-2-1; and the rear cover 3-3 of the bracket has a second recess that fits tightly with the second protrusion 3-2-2. The first protrusion 3-2-1 and the first recess cooperate to achieve a tight connection between the first snap-fit ​​assembly 3-2 and the main housing 3-1 of the bracket; the second protrusion 3-2-2 and the second recess cooperate to achieve a tight connection between the first snap-fit ​​assembly 3-2 and the rear cover 3-3 of the bracket, thereby achieving a closed connection between the main housing 3-1 of the bracket and the rear cover 3-3 of the bracket, forming a support cavity that can accommodate the first conductive component 4-1 in the connection module 4.

[0104] In some embodiments, such as Figure 11As shown, the VR main housing 2-7 includes a main body 2-7-4 and a first fixing element 2-7-5 fixedly connected to the main body 2-7-4; the support main housing 3-1 includes a support part 3-1-1 and a second fixing element 3-1-2 disposed at one end of the support part 3-1-1; the VR optical engine also includes a first rotating assembly 5; the first fixing element 2-7-5 cooperates with the second fixing element 3-1-2, and the first fixing element 2-7-5 is rotatably connected to the second fixing element 3-1-2 through the first rotating assembly 5.

[0105] For example, the support part 3-1-1 and the second fixing element 3-1-2 are welded into a single structure; the main body part 2-7-4 and the first fixing element 2-7-5 are welded into a single structure. Both the main body part 2-7-4 and the first fixing element 2-7-5 are provided with openings to form the first opening 2-7-3. The first conductive component 4-1 passes through the first opening 2-7-3 and falls into the support receiving cavity of the bracket module 3.

[0106] For example, the material of the first rotating component 5 can be polyoxymethylene (POM), which is a self-lubricating and wear-resistant material with a damping effect. When the VR headset module 2 rotates relative to the support module 3, the damping effect of the first rotating component 5 is used to achieve suspension and fixation of the VR headset module 2 at any position during the rotation process.

[0107] Furthermore, in this embodiment, the rotation of the VR headset module 2 relative to the support module 3 mainly refers to the adjustment of the pitch angle of the VR headset module 2. Specifically, as... Figure 9 and Figure 11 As shown, the first rotating assembly 5 includes two opposing first pads 5-1, two opposing first rotating shaft elements 5-2, and at least one first connecting element; the first fixing element 2-7-5 includes a first fixing part and two opposing first limiting structures 2-7-51 located at both ends of the first fixing part; the first fixing part and the two first limiting structures 2-7-51 define a first receiving part 2-7-52, and the second fixing element 3-1-2 falls into the first receiving part 2-7-52; the second fixing element 3-1-2 includes two first grooves located at both ends; the two first... A gasket 5-1 is respectively disposed in two first grooves and abuts against the bottom wall of the first groove; the first rotating shaft element 5-2 includes a first mating part 5-2-1 and a second mating part 5-2-2. The first mating part 5-2-1 is mated with the first limiting structure 2-7-51 so that the VR head-mounted display module 2 rotates and drives the first rotating shaft element 5-2 to rotate; the second mating part 5-2-2 is disposed in the first groove and abuts against the first gasket 5-1; the first fixing element 2-7-5 and the two first rotating shaft elements 5-2 are rotatably connected to the second fixing element 3-1-2 through the first connecting element.

[0108] For example, the first fixing part and the two first limiting structures 2-7-51 are integrally formed.

[0109] For example, such as Figure 9 and Figure 11 As shown, the first limiting structure 2-7-51 includes a first through hole extending along the axis of the first rotating assembly 5. The inner wall of the first limiting structure 2-7-51 for forming the first through hole is composed of a plurality of alternately arranged first protrusions and first recesses. The first mating part 5-2-1 of the first rotating shaft element 5-2 includes a second recess that mates with the first protrusion of the first limiting structure 2-7-51, and a second protrusion that mates with the first recess of the first limiting structure 2-7-51. The first mating part 5-2-1 mates with the first limiting structure 2-7-51 to realize the snap-fit ​​between the second fixing element 3-1-2 and the first rotating assembly 5. The second mating part 5-2-2 is disposed in the first groove and abuts against the first gasket 5-1; the first rotating shaft element 5-2 has a first threaded hole extending along its own axis, the first gasket 5-1 has a second threaded hole extending along its own axis, and the second fixing element 3-1-2 has a third threaded hole extending along its own axis. When the first rotating shaft element 5-2, the first gasket 5-1, and the second fixing element 3-1-2 are mated, they share the same reference axis. The first connecting element can be a screw, which passes through the first threaded hole, the second threaded hole, and the third threaded hole, and mates with the first rotating shaft element 5-2, the first gasket 5-1, and the second fixing element 3-1-2 to realize the rotational connection between the first rotating assembly 5 and the first fixing element 2-7-5, thereby realizing the adjustment of the tilt angle of the VR headset module 2.

[0110] For example, the materials of the first pad 5-1 and the first rotating shaft element 5-2 can both be POM material, so as to achieve the suspension and fixation of the VR head-mounted display module 2 at any position during rotation.

[0111] For example, one first connecting element can be provided, which passes through the first threaded hole, the second threaded hole, and the third threaded hole to achieve a rotatable connection between the first rotating component 5 and the first fixed element 2-7-5. Alternatively, two opposing first connecting elements can be provided, which pass through two opposing first rotating shaft elements 5-2 and the first washer 5-1, and part of the third threaded hole of the first fixed element 2-7-5, respectively, which can also achieve a rotatable connection between the first rotating component 5 and the first fixed element 2-7-5.

[0112] In some embodiments, in conjunction with the above embodiments, the first connecting element (i.e., the screw) can be fixed with thread-locking adhesive to prevent the shaft from loosening.

[0113] In some embodiments, depending on the actual application scenario, the actual range of the tilt angle that the VR headset module 2 can be adjusted can be set to avoid excessive adjustment range causing loose connections of internal electronic components and affecting the stability of signal transmission.

[0114] Specifically, such as Figure 11 As shown, the second mating part 5-2-2 has a first limiting groove 5-2-21; the second fixing element 3-1-2 also includes at least one first limiting block 3-1-21 fixed to the inner wall of the first groove; the first limiting block 3-1-21 passes through the first notch 5-1-1 of the first gasket 5-1 and falls into the first limiting groove 5-2-21 on the second mating part 5-2-2; when the VR head-mounted display module 2 is driven to rotate, its rotation angle range is limited by the first limiting block 3-1-21.

[0115] On a reference plane perpendicular to the reference axis, the ratio of the length of the projected outer contour of the first limiting groove 5-2-21 to the length of the projected outer contour of the second mating part 5-2-2 is also the ratio of the maximum value of the rotation angle range to 360°. The first limiting groove 5-2-21 can be set according to the rotation angle limited by the actual application scenario.

[0116] This embodiment utilizes the first limiting block 3-1-21 to limit the rotation angle range (i.e., the pitch angle range) of the VR headset module 2, effectively preventing excessive adjustment from causing loose connections of internal electronic components and ensuring signal transmission stability. Additionally, the first limiting block 3-1-21 can also limit the rotation direction of the VR headset module 2 in its initial state. For example, with the mask 2-1 of the VR headset module 2 initially aligned parallel to the bottom surface of the base 1, the first limiting block 3-1-21 can be used to limit the VR headset module 2's pitch angle adjustment in a counter-clockwise direction.

[0117] For example, one first limiting block 3-1-21 can be set; or two first limiting blocks 3-1-21 can be set, for example, the first limiting blocks 3-1-21 can be set on the inner walls of the two first grooves respectively, to improve the limiting accuracy and reliability.

[0118] In some embodiments, with the initial state of the VR headset module 2 and the mask 2-1 facing parallel to the bottom surface of the base 1 as a reference, the rotation angle range of the VR headset module 2 is between 0 and 90° in the counterclockwise direction.

[0119] In some embodiments, such as Figure 9 and Figure 11 As shown, the first rotating component 5 also includes two opposing first decorative pieces 5-3, which fall into the first through hole of the first limiting structure 2-7-51 and abut against the first rotating shaft element 5-2, for covering the decoration.

[0120] In some embodiments, the main housing 3-1 of the support includes a support portion 3-1-1 and a third fixing element 3-1-3 disposed at one end of the support portion 3-1-1; the base 1 includes a main housing 1-2 of the base and a fourth fixing element 1-3 fixedly connected to the main housing 1-2 of the base; the VR optical engine also includes a second rotating assembly 6; the fourth fixing element 1-3 cooperates with the third fixing element 3-1-3 and is rotatably connected through the second rotating assembly 6, and can be used to achieve folding and storage.

[0121] like Figure 10 and Figure 11 As shown, the third fixing element 3-1-3 in this embodiment has a similar structure to the second fixing element 3-1-2, and the fourth fixing element 1-3 has a similar structure to the first fixing element 2-7-5.

[0122] For example, the support part 3-1-1 and the third fixing element 3-1-3 are welded into a whole structure; the base main shell 1-2 and the fourth fixing element 1-3 are welded into a whole structure. The base main shell 1-2 and the fourth fixing element 1-3 are both provided with openings to form a second opening 1-2-1. The third conductive component 4-3 passes through the second opening 1-2-1 and falls into the base receiving cavity of the base 1.

[0123] For example, the material of the second rotating component 6 can be polyoxymethylene (POM), which is a self-lubricating and wear-resistant material with a damping effect. When the support module 3 rotates relative to the base 1, the damping effect of the second rotating component 6 is used to achieve suspension and fixation at any position during the rotation of the support module 3, thereby realizing the adjustment of the VR headset module 2 at any height to adapt to different user heights.

[0124] Furthermore, in this embodiment, the rotation of the bracket module 3 relative to the base 1 mainly refers to the folding rotation achieved by using the second rotating component 6 near the base 1 as the rotation axis.

[0125] Specifically, such as Figure 10As shown, the second rotating assembly 6 includes two opposing second pads 6-1, two opposing second rotating shaft elements 6-2, and at least one second connecting element; the fourth fixing element 1-3 includes a second fixing part and two opposing second limiting structures 1-3-1 located at both ends of the second fixing part; the second fixing part and the two second limiting structures 1-3-1 define a second receiving part, and the third fixing element 3-1-3 falls into the second receiving part; the third fixing element 3-1-3 includes two second grooves located at both ends; the two second pads 6-1 The second rotating shaft element 6-2 is respectively disposed in the two second grooves and abuts against the bottom wall of the second grooves; the third rotating shaft element 6-2 includes a third mating part 6-2-1 and a fourth mating part 6-2-2. The third mating part 6-2-1 is mated with the second limiting structure 1-3-1 so that the bracket module 3 rotates and drives the second rotating shaft element 6-2 to rotate; the fourth mating part 6-2-2 is disposed in the second groove and abuts against the second gasket 6-1; the third fixing element 3-1-3 and the two second rotating shaft elements 6-2 are rotatably connected to the fourth fixing element 1-3 through the second connecting element.

[0126] For example, the second fixing part and the two second limiting structures 1-3-1 are integrally formed structures.

[0127] For example, the second limiting structure 1-3-1 is the same as the first limiting structure 2-7-51, as detailed in the following document. Figure 11 The diagram shows the first limiting structure 2-7-51. The second limiting structure 1-3-1 includes a second through hole extending along the axis of the second rotating assembly 6. The inner wall of the second limiting structure 1-3-1 forming the second through hole is composed of a plurality of alternately arranged third protrusions and third recesses. The third mating part 6-2-1 of the second rotating shaft element 6-2 includes a fourth recess that mates with the third protrusion of the second limiting structure 1-3-1, and a fourth protrusion that mates with the third recess of the second limiting structure 1-3-1. The third mating part 6-2-1 mates with the second limiting structure 1-3-1 to achieve the snap-fit ​​between the fourth fixing element 1-3 and the second rotating assembly 6. The fourth mating part 6-2-2 is disposed in the second groove and abuts against the second gasket 6-1; the second rotating shaft element 6-2 has a fourth threaded hole extending along its own axis, the second gasket 6-1 has a fifth threaded hole extending along its own axis, and the third fixing element 3-1-3 has a sixth threaded hole extending along its own axis. When the second rotating shaft element 6-2, the second gasket 6-1, and the third fixing element 3-1-3 are mated, they share the same reference axis. The second connecting element can be a screw, which passes through the fourth, fifth, and sixth threaded holes and mates with the second rotating shaft element 6-2, the second gasket 6-1, and the third fixing element 3-1-3 to realize the rotational connection between the second rotating assembly 6 and the fourth fixing element 1-3, thereby realizing the adjustment of the rotation angle of the bracket module 3.

[0128] For example, the second pad 6-1 and the second rotating shaft element 6-2 can both be made of POM material, so as to enable the bracket module 3 to be suspended and fixed at any position during rotation, thereby enabling the VR head-mounted display module 2 to be adjusted to any height, and thus adapt to the height of different people.

[0129] For example, one second connecting element can be provided, passing through the fourth, fifth, and sixth threaded holes to achieve a rotatable connection between the second rotating assembly 6 and the third fixed element 3-1-3. Alternatively, two opposing second connecting elements can be provided, passing through the two opposing second rotating shaft elements 6-2 and the second washer 6-1, and part of the sixth threaded hole of the third fixed element 3-1-3, respectively, which can also achieve a rotatable connection between the second rotating assembly 6 and the third fixed element 3-1-3.

[0130] In some embodiments, in conjunction with the above embodiments, the second connecting element (i.e., the screw) can be fixed with thread-locking adhesive to prevent the shaft from loosening.

[0131] In some embodiments, depending on the actual application scenario, the actual range of the adjustable folding angle of the bracket module 3 can be set to avoid excessive folding causing loose connections of internal electronic components and affecting the stability of signal transmission.

[0132] For example, the fourth mating part 6-2-2 has the same structure as the second mating part 5-2-2, as can be seen in the following example. Figure 11 The structural diagram of the second mating part 5-2-2 is shown. Specifically, the fourth mating part 6-2-2 has a second limiting groove; the third fixing element 3-1-3 also includes at least one second limiting block fixed to the inner wall of the second groove; the second limiting block passes through the second notch of the second gasket 6-1 and falls into the second limiting groove on the fourth mating part 6-2-2; when the bracket module 3 is driven to rotate, its rotation angle range is limited by the second limiting block.

[0133] On a reference plane perpendicular to the reference axis, the ratio of the length of the projected outer contour of the second limiting groove to the length of the projected outer contour of the fourth mating part 6-2-2 is also the ratio of the maximum value of the rotation angle range to 360°. The second limiting groove can be set according to the rotation angle limited by the actual application scenario.

[0134] This embodiment utilizes a second limiting block to restrict the rotation angle range (i.e., the pitch angle range) of the bracket module 3, effectively preventing excessive adjustment from causing loosening of internal electronic component connections and ensuring signal transmission stability. Additionally, the second limiting block can also restrict the rotation direction of the bracket module 3 in its initial state. For example, with the bracket module 3 initially perpendicular to the bottom surface of the base 1 as a reference, the second limiting block restricts the bracket module 3 to adjust its tilt angle clockwise. When the extension direction of the bracket module 3 is parallel to the bottom surface of the base 1, i.e., when the tilt angle is 90°, the bracket module 3 is folded and stored.

[0135] For example, one second limiting block can be set; or two second limiting blocks can be set, for example, the second limiting blocks can be set on the inner walls of two second grooves respectively, to improve the limiting accuracy and reliability.

[0136] In some embodiments, with the bracket module 3 initially perpendicular to the bottom surface of the base 1 as a reference, the rotation angle range of the bracket module 3 is between 0 and 90° in the clockwise direction.

[0137] In some embodiments, such as Figure 10 As shown, the second rotating component 6 also includes two opposing second decorative pieces 6-3, which fall into the second through hole of the second limiting structure 1-3-1 and abut against the second rotating shaft element 6-2 for covering decoration.

[0138] The VR optical engine housing provided in this embodiment adopts a screwless design, achieving product integrity and aesthetics.

[0139] In some embodiments, such as Figure 4 As shown, the VR headset module 2 also includes a heat-conducting component 2-6; the heat-conducting component 2-6 is fixed on the side of the VR main housing 2-7 away from the bracket module 3; the VR display module 2-5 is in contact with the heat-conducting component 2-6.

[0140] For example, the material of the heat-conducting component 2-6 can be graphite sheet or copper foil to accelerate the conduction of heat generated by the VR display module 2-5 to the VR main housing 2-7.

[0141] Furthermore, such as Figure 4 As shown, the heat-conducting component 2-6 is a U-shaped sheet, including a first sheet that contacts the VR display module 2-5, a second sheet that contacts the VR main housing 2-7, and a third sheet that connects the first sheet and the second sheet.

[0142] The third sheet is used to connect the first sheet and the second sheet. In this embodiment, a surface contact method is adopted to accelerate the heat generated by the VR display module 2-5 to the first sheet. At the same time, since the heat conduction component 2-6 is a U-shaped sheet, there is a gap between the first sheet and the second sheet, which further accelerates the heat diffusion. Meanwhile, the heat of the first sheet is conducted to the second sheet through the third sheet. The second sheet and the VR main shell 2-7 adopt a surface contact method to further accelerate the heat diffusion to the external environment.

[0143] In this embodiment, a U-shaped sheet is used as a heat-conducting component, which effectively prevents the VR display module 2-5 from overheating, while saving the volume of the integrated heat sink of the VR head-mounted display module 2.

[0144] In some embodiments, such as Figure 4 and Figure 5 As shown, the VR display module 2-5 also includes a VR front cover 2-4, a fixedly connected mask 2-1, and a mask frame 2-2; the VR front cover 2-4 is fixedly connected to the VR main housing 2-7 through a second snap-fit ​​assembly 2-4-1; the mask frame 2-2 is detachably connected to the VR front cover 2-4.

[0145] For example, the second snap-fit ​​component 2-4-1 and the VR front cover 2-4 are integrally formed structures. The second snap-fit ​​component 2-4-1 cooperates with the VR main shell 2-7 to achieve a detachable connection. Here, detachability generally refers to disassembly in maintenance scenarios.

[0146] For example, the mask frame 2-2 and the VR front cover 2-4 can be detachably connected by a snap-fit ​​connection, or they can be detachably connected by a magnetic attraction. Magnetic attraction is more convenient for disassembly than snap-fit ​​connection. The detachable connection between the mask frame 2-2 and the VR front cover 2-4 is for storage purposes. That is, after use, the user can remove the mask frame 2-2 and the connected mask 2-1 from the VR front cover 2-4. At this time, the thickness of the VR headset module 2 is within 10mm, achieving a thinner and lighter VR headset.

[0147] For example, the mask 2-1 has a two-layer structure, with an outer layer of fabric and an inner layer of sponge to improve user comfort. The mask frame 2-2 is used to support the mask 2-1 and is glued together with the mask 2-1 to form the VR mask 2-1.

[0148] In some embodiments, such as Figure 4 and Figure 5 As shown, the VR main housing 2-7 is provided with a first heat dissipation hole 2-7-1 and a second heat dissipation hole 2-7-2 that are arranged opposite to each other.

[0149] Here, the VR main housing 2-7 has an air inlet (first heat dissipation hole 2-7-1) and an air outlet (second heat dissipation hole 2-7-2) at the bottom and top respectively. The area of ​​the air inlet (first heat dissipation hole 2-7-1) is generally 1.5 to 2 times the area of ​​the air outlet (second heat dissipation hole 2-7-2). This can easily form a "chimney effect", which is conducive to natural air convection and accelerates the heat dissipation of the VR display module 2-5.

[0150] In conjunction with the above embodiments, the VR headset module 2 of this disclosure effectively prevents the temperature of the VR headset module 2 from becoming too high by accelerating air convection and heat conduction, and also saves the volume of the heat sink.

[0151] In some embodiments, such as Figure 7 and Figure 12 As shown, the VR optical engine also includes data cable 1-4; data cable 1-4 is connected to the drive module 1-1 and the external terminal respectively. Specifically, data cable 1-4 is electrically connected to the drive circuit board in the drive module 1-1, and is used to input the video signal from the external terminal to the drive circuit board.

[0152] Here, the external terminal can be a display terminal such as a computer.

[0153] In some embodiments, such as Figure 7 and Figure 12 As shown, silicone feet 1-5 are installed on the side of the base 1 facing away from the VR headset module 2 to prevent slippage and protect the base 1. The base 1 mainly serves to lower the overall center of gravity, preventing the support module 3 and / or the VR headset module 2 from tilting or tipping over when bent. Its material is usually a high-density metal.

[0154] The above is a complete description of the ultrathin VR optical engine structure provided in the embodiments of this disclosure.

[0155] The VR optical engine is assembled as follows:

[0156] First, assemble the left and right optical transducers 2-5-1 and 2-5-2. Then, fit the first polarization limiting frame 2-5-12 onto the outside of the first connector sub-assembly 2-5-11 (BTB female connector), fit the second polarization limiting frame 2-5-22 onto the outside of the second connector sub-assembly 2-5-21 (BTB female connector), and insert the third connector sub-assembly 4-2-4 (BTB male connector) into the first connector sub-assembly 2-5-11 (BTB female connector) and tighten it with screws. Insert the fourth connector sub-assembly 4-2-5 (BTB male connector) into the second connector sub-assembly 2-5-21 (BTB female connector) and tighten it with screws. Next, use the first wire clip 2-5-3 to clamp and fix the second conductive part 4-2-2, and use the second wire clip 2-5-4 to clamp and fix the third conductive part 4-2-3. Pass the connecting module 4 through the first opening 2-7-3 in the VR main housing 2-7 to the back. Then, a U-shaped sheet is formed, and the first sheet is attached to the back of the VR display module 2-5, while the second sheet is attached to the inside of the VR main housing 2-7. Simultaneously, the VR display module 2-5 is fixed to the corresponding position on the VR main housing 2-7. The face mask 2-1 and the face mask frame 2-2 are glued together to form the VR face mask 2-1, and magnets 2-3 are attached to the corresponding positions on the face mask frame 2-2. At the same time, magnets 2-3 are also attached to the corresponding positions on the VR front cover 2-4, ensuring that the magnets 2-3 on the face mask frame 2-2 and the VR front cover 2-4 can attract each other. The bracket main housing 3-1 is placed into the corresponding position on the VR main housing 2-7 (the second fixing element 3-1-2 falls into the first receiving part 2-7-52), and the components of the first rotating assembly 5 are installed into the bracket main housing 3-1 and the VR main housing 2-7, and then tightened with screws. Place the main housing 3-1 of the support frame into the corresponding position of the main housing 1-2 of the base (the third fixing element 3-1-3 falls into the second receiving part). Install the components of the second rotating assembly 6 into the main housing 3-1 of the support frame and the main housing 1-2 of the base, and tighten them with screws. At the same time, pass the connecting module 4 through the second opening 1-2-1 in the main housing 1-2 of the base to the receiving cavity of the base. Connect the drive module 1-1 to the third conductive component 4-3 (the corresponding position of the IC can be made to make contact with the thermal pad). Attach the silicone foot pads 1-5 to the corresponding positions of the base 1. Connect the data cable 1-4 to the corresponding interface of the drive circuit board and connect it to the computer to debug the VR optical engine display effect. After the hardware and software debugging is completed, snap the VR front cover 2-4 of the VR headset module 2 into the VR main housing 2-7, and fix the VR mask 2-1 with magnetic attraction. Install the second snap-fit ​​assembly 2-4-1 into the corresponding position of the main housing 3-1 of the support frame, and forcefully snap the rear cover 3-3 of the support frame into place. The assembly of the support module 3 is now complete. Adjust the damping effect of the first rotating component 5 and the second rotating component 6 by screwing until the VR headset module 2 and the bracket module 3 can be fixed in any position to achieve a hovering effect. Finally, fix the screws with threaded adhesive to prevent the rotating shaft from loosening.

[0157] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
