Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0048] Current head-mounted display devices, such as AR glasses or VR glasses, rely on the electrical connections of electronic components located in the frame and temples to ensure normal operation. To meet users' wearing and storage needs, hinges are typically used to connect the temples and frame, with electronic circuitry running inside the hinges. However, under different operating conditions, external liquids can easily enter the device through the movement gaps of the hinges, causing circuit failure and affecting product reliability.
[0049] To address this technical problem, the present invention proposes a head-mounted display device 100, wherein the head-mounted display device 100 is, for example but not limited to, AR glasses, VR glasses, and MR glasses. Taking AR glasses as an example, its frame 10 is typically provided with a display module to provide image information to the user's eyes.
[0050] It should be noted that as the temple 20 gradually opens from the folded state, the free end of the temple 20 moves away from the frame 10, while when switching to the folded state, the free end of the temple 20 approaches or abuts against the frame 10.
[0051] Please see Figures 1 to 10 In one embodiment of the present invention, the head-mounted display device 100 includes a frame 10, temples 20, a hinge structure 30, and a sealing structure 40. The frame 10 has a first cavity 13; the temples 20 have a second cavity 23; the hinge structure 30 connects the frame 10 and the temples 20; two sealing structures 40 are provided and are respectively sealed to the first cavity 13 and the second cavity 23. The sealing structure 40 includes a sealing plate 41 and a sealant 46. The sealing plate 41 has a through hole 421 through which a power supply connector 50 passes. The power supply connector 50 and the sealing plate 41 are connected by the sealant 46. This reduces the risk of external liquid entering the first cavity 13 and the second cavity 23 and improves the reliability of the head-mounted display device 100.
[0052] In the technical solution of the present invention, the through hole 421 on the sealing structure 40 ensures that the electrical connector 50 passes through the first cavity 13 and the second cavity 23, completing the electrical connection between the relevant electronic components located in the frame 10 and the temple 20, and realizing the display function of the head-mounted display device 100. The sealing connection between the two sealing structures 40 and the first cavity 13 and the second cavity 23 respectively, and the sealing connection of the electrical connector 50 on the sealing plate 41 by the sealant 46, not only improves the installation stability of the electrical connector 50 on the head-mounted display device 100, but also effectively ensures that external liquids cannot enter the first cavity 13 and the second cavity 23, reducing the risk of damage to the electronic components inside the head-mounted display device 100, giving it a high level of waterproof function, and improving the safety and reliability of the head-mounted display device 100.
[0053] Furthermore, due to the properties of the sealant 46, it is easy to be compatible with electrical connectors 50 of different sizes, improving the assemblability of electrical connectors 50, and thus improving the assembly efficiency of the head-mounted display device 100.
[0054] It should be noted that the electrical connector 50 includes, but is not limited to, wire harness 501, flexible circuit board 502, and heat sink. The wire harness 501 can specifically be a signal line, which can ensure the electrical connection between relevant electronic components located in the frame 10 and temple 20, and realize the display function of the head-mounted display device 100. On the other hand, since the electrical connector 50 is a flexible part, it can extend or avoid the hinge structure 30 when it moves, reducing the risk of circuit failure caused by circuit disconnection, and improving the reliability of movement and electrical connection.
[0055] Compared to using a fully encapsulated sealing sleeve, it is difficult to ensure the assemblability of different wire harnesses 501 when the sealing interface is complex. In this embodiment, two sealing structures 40 are provided for the frame 10 and temple 20, and both are located away from the hinge structure 30. The sealing structure 40 includes a sealing plate 41 and a sealant 46. The sealing plate 41 is sealed to the cavity wall of the corresponding chamber, forming a first sealing interface extending circumferentially along the first cavity 13 and a second sealing interface extending circumferentially along the second cavity 23, blocking external liquid from entering through the first sealing interface (between the sealing plate 41 and the cavity wall of the first cavity 13) and the second sealing interface (between the sealing plate 41 and the cavity wall of the first cavity 13). Further inflow between the walls of the second cavity 23 is prevented to avoid damaging related electronic components; a through hole 421 is provided on the sealing plate 41 along the extension direction of the electrical connector 50. The cross-sectional area of the through hole 421 is larger than that of the electrical connector 50, which facilitates the installation of the electrical connector 50 on the sealing plate 41. In addition, the use of sealant 46 achieves wire sealing, which facilitates the sealing of various types of wire harnesses 501 and complex sealing interfaces with various through hole 421 shapes, improves the assemblability of the electrical connector 50 and the versatility of the sealing structure 40, and further blocks the inflow of external liquid from the complex sealing interface into the first cavity 13 and the second cavity 23.
[0056] Specifically, the sealant 46 can be configured as a UV adhesive. By injecting the sealant 46 to fill the gap between the electrical connector 50 and the sealing plate 41, and then curing the adhesive with a UV lamp compatible with the UV adhesive, the sealing reliability of the sealing structure 40 is improved. Simultaneously, it ensures the electrical connector 50 is fixed to the sealing plate 41, reducing the risk of electrical connection disconnection due to movement, thereby guaranteeing the normal operation of the display function. Of course, other sealants 46 capable of curing and sealing, such as silicone, are also applicable and are not limited here.
[0057] The two ends of the hinge structure 30 can extend into the first cavity 13 and the second cavity 23 respectively, or connect to the openings of the first cavity 13 and the second cavity 23. This also enables the connection between the hinge structure 30 and the frame 10 and the temple 20, ensuring the movement of the temple 20 relative to the frame 10. When one end of the electrical connector 50 inside the temple 20 crosses the hinge structure 30 and enters the frame 10, the electrical connector 50 is provided with a dynamic margin corresponding to the hinge structure 30. That is, the dynamic margin is located between the two sealing structures 40. During the movement of the hinge structure 30, the electrical connector 50 can match the movement trajectory of the hinge structure 30 through deformation methods such as stretching, compression, and bending, reducing the structural influence of the hinge structure 30 on the electrical connector 50, while ensuring the sealing effect of the sealing structure 40.
[0058] Please refer to 6 and 7. In the embodiments of the present invention, the electrical connector 50 is provided with a marking structure. The marking structure is located away from the hinge structure 30. The sealing structure 40 wraps the marking structure with the sealant 46. It can be understood that by reserving a marking structure, such as a marking line, for line positioning, the sealing structure 40 can cover the marking structure, enabling the sealing structure 40 to be quickly positioned on the electrical connector 50, improving the assembly efficiency of the electrical connector 50 and the sealing structure 40. It is also beneficial to limit the dynamic margin on the electrical connector 50 by the two marking structures on the electrical connector 50, and then, with the help of the sealing structure 40 wrapped around the marking structure, the dynamic margin is set outside the sealing interface. While ensuring the sealing performance, it ensures the folding and opening movements of the temple 20 relative to the frame 10, and does not affect the display function of the head-mounted display device 100.
[0059] Specifically, in an embodiment of the present invention, the marking structure is configured to be formed in the marking groove 51 of the electrical connector 50, such as... Figure 7 As shown, both the wire harness 501 and the flexible circuit board 502 are provided with marking grooves 51. On the one hand, the marking grooves 51 can be used to determine the relative position between the wire harness 501 and the flexible circuit board 502. On the other hand, when the sealant 46 is injected into the sealing plate 41, the marking grooves 51 increase the effective connection area between the electrical connector 50 and the sealant 46, which helps to improve the connection strength between the electrical connector 50 and the sealant 46 and improve the sealing and waterproofing effect.
[0060] The marking groove 51 on the wire harness 501 is an annular groove extending around the axis of the wire harness 501, and the marking groove 51 on the flexible circuit board 502 is a straight groove facing the wire harness 501. Of course, the marking groove 51 can also be a through groove that penetrates the flexible circuit board 502, or the marking groove 51 can be set on the outer peripheral surface of the flexible circuit board 502.
[0061] Please see Figures 3 to 8 In an embodiment of the present invention, the sealing plate 41 includes an upper wire guide plate 411 and a lower wire guide plate 412. The upper wire guide plate 411 and the lower wire guide plate 412 are connected and form the through hole 421. Furthermore, by sequentially placing the lower wire guide plate 412, the electrical connector 50, and the upper wire guide plate 411, the electrical connector 50 can be disposed within the through hole 421. Moreover, by aligning the marking structure with the hole wall of the through hole 421, the sealing plate 41 is positioned on the electrical connector 50. The connection methods of the upper wire guide plate 411 and the lower wire guide plate 412 include, but are not limited to, insert fitting, plugging, bonding, and screw connection.
[0062] Taking the example of using UV adhesive 46 as the sealant and at least some of the through holes 421 formed in the lower wiring board 412, firstly, UV adhesive is injected into the through holes 421 on the lower wiring board 412. The electrical connector 50 is then immersed in the UV adhesive according to its marked structure. Next, the upper wiring board 411 is assembled onto the lower wiring board 412. This ensures that the gap (adhesive storage channel) between the upper wiring board 411, the lower wiring board 412, and the electrical connector 50 is fully filled with UV adhesive. Then, a UV lamp is used to irradiate the UV adhesive in all directions of the sealing plate 41, so that the UV adhesive is completely cured, thereby achieving the sealing structure 40 for the electrical connector 50. Of course, in other embodiments, at least some of the through holes 421 are formed in the upper wiring board 411.
[0063] Please see Figure 6 and Figure 8 In an embodiment of the present invention, a glue storage channel for injecting the sealant 46 is also formed between the upper wire plate 411 and the lower wire plate 412. The glue storage channel includes at least a glue storage space 431 between the electrical connector 50 and the hole wall of the through hole 421. Thus, by injecting the sealant 46 into the glue storage space 431, the sealing of the through hole 421 is ensured, thereby reducing the possibility of external liquid entering the first cavity 13 or the second cavity 23 through the through hole 421. At the same time, it ensures a stable connection between the electrical connector 50 and the sealing structure 40.
[0064] Furthermore, in an embodiment of the present invention, the adhesive storage channel further includes a first adhesive storage channel 432 communicating with the adhesive storage space 431. The first adhesive storage channel 432 is arranged circumferentially along the through hole 421 and is recessed in a direction away from the center of the through hole 421. This helps to increase the effective connection area between the sealant 46 and the sealing plate 41, thereby effectively reducing the risk of the sealing structure 40 delaminating due to external liquid impact on the front, improving the connection strength between the sealing plate 41 and the sealant 46, and improving the sealing and waterproofing effect.
[0065] When the through hole 421 is formed on the lower wire guide plate 412, the first glue storage channel 432 is disposed on the lower wire guide plate 412 and is disposed around the axis of the through hole 421. At this time, the first glue storage channel 432 penetrates the surface of the lower wire guide plate 412 facing the upper wire guide plate 411. Thus, by providing a groove in the upper wire guide plate 411 to connect the first glue storage channel 432, a portion of the first glue storage channel 432 can be formed in the upper wire guide plate 411, thereby further increasing the connection area between the sealant 46 and the sealing plate 41, enhancing the connection strength between the sealant 46 and the sealing plate 41, and also improving the connection strength between the upper wire guide plate 411 and the lower wire guide plate 412. Of course, in other embodiments, the first glue storage channel 432 is only disposed on the lower wire guide plate 412.
[0066] Furthermore, in an embodiment of the present invention, the glue storage channel further includes a second glue storage channel 433 communicating with the glue storage space 431. The second glue storage channel 433 is formed between the upper wire guide plate 411 and the lower wire guide plate 412. It can be understood that the upper wire guide plate 411 and the lower wire guide plate 412 are spaced apart so that the second glue storage channel 433 is formed between the two opposing surfaces of the upper wire guide plate 411 and the lower wire guide plate 412. Of course, a groove communicating with the second glue storage channel 433 may also be provided in the upper wire guide plate 411 and / or the lower wire guide plate 412.
[0067] Since the second glue storage channel 433 is connected to the glue storage space 431, the injected sealant 46 can flow to the second glue storage channel 433, thereby increasing the effective contact area between the sealant 46 and the sealing plate 41, improving the connection strength between the sealing plate 41 and the sealant 46, and strengthening the connection between the upper wire plate 411 and the lower wire plate 412.
[0068] Specifically, in an embodiment of the present invention, one of the upper wire guide plate 411 and the lower wire guide plate 412 is provided with a positioning post 441, and the other is provided with a positioning hole 442 that engages with the positioning post 441. The depth of the positioning hole 442 is less than the height of the positioning post 441, so that part of the positioning post 441 is located between the upper wire guide plate 411 and the lower wire guide plate 412, i.e., exposed in the second adhesive storage channel 433. When the sealant 46 is located in the second adhesive storage channel 433, the sealant 46 wraps around the positioning post 441, which helps to strengthen the connection between the upper wire guide plate 411 and the lower wire guide plate 412 and effectively reduces the risk of the upper wire guide plate 411 and the lower wire guide plate 412 detaching from each other. Of course, during this process, part of the sealant 46 can enter the positioning hole 442.
[0069] To ensure the sealing performance at the first and second sealing interfaces, in an embodiment of the present invention, a sealing ring 451 is embedded on the outer peripheral surface of the sealing plate 41. That is, an annular groove is formed on the outer peripheral surface of the sealing plate 41. By inserting the sealing ring 451 into the annular groove, the sealing ring 451 is fixedly connected to the sealing plate 41. Therefore, when the sealing structure 40 is fixed in the first cavity 13 or the second cavity 23, the sealing ring 451 can achieve a reliable seal at the first and second sealing interfaces by being squeezed at the first or second sealing interface, thereby improving the waterproof effect of the head-mounted display device 100.
[0070] Optionally, in an embodiment of the present invention, the sealing plate 41 is configured as a transparent plastic plate. It is understood that the plastic plate is a rigid material. When the sealing structure 40 and the frame 10 or temple 20 are sealed by compressing the sealing ring 451, the plastic plate can effectively reduce the possibility of the electrical connector 50 being compressed. This helps to ensure the connection function of the electrical connector 50. Furthermore, setting the sealing plate 41 as a transparent plate can facilitate the irradiation of the UV adhesive by the UV lamp to a certain extent, thereby accelerating the curing efficiency. It also facilitates the user's inspection of the sealing structure 40.
[0071] Please see Figure 9 and Figure 10 In an embodiment of the present invention, the sealing plate 41 includes a plate body 413 and a through hole 421 penetrating the plate body 413. The plate body 413 is configured as a silicone component. The electrical connector 50 can be pre-fixed to the wall of the through hole 421 using sealant 46. The sealant 46 includes double-sided adhesive, specifically waterproof double-sided adhesive. During this process, the marking structures of the flexible circuit board 502 and the wire harness 501, as well as the wall of the through hole 421, need to be aligned first, and then the double-sided adhesive is used for attachment. Next, the sealant 46 also includes silicone. The silicone is injected into the through hole 421 to achieve wire sealing of the electrical connector 50 by the sealing structure 40. The through-hole 421 is specifically the extending direction of the electrical connector 50.
[0072] Since the plate body 413 is made entirely of silicone material, when the sealing structure 40 is installed into the frame 10 or temple 20, the compression of the plate body 413 can achieve a reliable seal at the first and second sealing interfaces, improving the waterproof effect of the head-mounted display device 100. Of course, in other embodiments, the plate body 413 can also adopt other structural components with specific elastic deformation capabilities, and the sealant 46 can also be made of other materials.
[0073] Furthermore, in an embodiment of the present invention, the plate body 413 is also provided with a groove 422 communicating with the through hole 421. The groove 422 is used for the sealant 46 to be poured from the groove 422 into the through hole 421. This arrangement facilitates the pouring of the sealant 46 and simplifies the sealing structure 40.
[0074] The groove 422 and the through hole 421 are connected and form a stepped structure, which facilitates increasing the effective connection area between the sealant 46 and the plate body 413, improving the connection strength between the sealant 46 and the plate body 413, and improving the waterproof effect. Specifically, in this embodiment, the groove 422 can be opened on the upper surface of the plate body 413 to facilitate the injection of the sealant 46 from top to bottom. However, in other embodiments, the groove 422 can also be opened on the side of the plate body 413.
[0075] Please see Figure 10 In an embodiment of the present invention, at least one sealing rib 452 is provided on the outer periphery of the sealing plate 41, specifically, at least one sealing rib 452 is provided on the outer periphery of the plate body 413. With this arrangement, when the sealing structure 40 is installed into the frame 10 or temple 20, the compression of the sealing rib 452 achieves a reliable seal at the first and second sealing interfaces. Furthermore, when external liquid directly impacts the sealing structure 40, the deformation of the plate body 413 and the sealing rib 452 helps to further increase the compression of the sealing rib 452, further forming a seal and achieving an advanced waterproof effect. In this embodiment, two sealing ribs 452 are spaced apart on the outer periphery of the plate body 413 to facilitate multi-level sealing, wherein the protrusion height of the two sealing ribs 452 is the same; however, in other embodiments, the sealing ribs 452 include, but are not limited to, two sealing ribs 452; some sealing ribs 452 have inconsistent protrusion heights.
[0076] Please see Figure 3 and Figure 4 In an embodiment of the present invention, the cavity wall of the first cavity 13 is provided with a first positioning groove 131 matching the sealing structure 40, and the cavity wall of the second cavity 23 is provided with a second positioning groove 231 matching the sealing structure 40. It can be understood that, on the basis of ensuring the structural strength and rigidity of the frame 10 and the temple 20, the outer contour of the sealing structure 40 is the same as the shape of the first cavity 13 and the second cavity 23, so that the sealing structure 40 can be well embedded in the first positioning groove 131 or the second positioning groove 231, and it is also convenient for the sealing structure 40 to adapt to the assembly operation of the frame 10 and the temple 20, thereby facilitating waterproof sealing in a smaller assembly space (first cavity 13 and second cavity 23), while saving the space occupied by the sealing structure 40 and facilitating the assembly of other electronic components.
[0077] Specifically, the frame 10 includes a front frame 11 and a rear frame 12 connected together, and the temple 20 includes a temple outer shell 21 and a temple inner shell 22 connected together. The front frame 11 and the rear frame 12 are connected to form a first cavity 13, which can be fixed by means of snaps, adhesives, etc. In addition, by assembling the front frame 11 and the rear frame 12, the sealing ring 451 or the sealing rib 452 can be squeezed during the shell assembly to ensure that the sealing structure 40 is in close contact with the cavity wall of the first cavity 13, so as to achieve a better sealing effect. Similarly, the temple outer shell 21 and the temple inner shell 22 are connected to form a second cavity 23, which can be fixed by means of snaps, adhesives, etc. In addition, by assembling the temple outer shell 21 and the temple inner shell 22, the sealing ring 451 or the sealing rib 452 can be squeezed during the shell assembly to ensure that the sealing structure 40 is in close contact with the cavity wall of the second cavity 23, so as to achieve a better sealing effect. More specifically, the lips of the front frame 11 and the rear frame 12 are sealed with hot melt adhesive, and the lips of the temple outer shell 21 and the temple inner shell 22 are sealed with hot melt adhesive, further enhancing the overall sealing of the head-mounted display device 100.
[0078] Please see Figure 1 and Figure 5 In an embodiment of the present invention, an installation gap 101 is formed between the temple 20 and the frame 10; thereby ensuring that there is sufficient movement margin between the temple 20 and the frame 10, facilitating the folding and opening movement of the temple 20 relative to the frame 10, reducing interference between the two, and thus ensuring the lifespan and smooth movement of the temple 20 and the frame 10.
[0079] The hinge structure 30 includes a hinge shaft 31 and a first hinge arm 32 and a second hinge arm 33 rotatably connected to the hinge shaft 31. The hinge shaft 31 is located in the mounting gap 101. The first hinge arm 32 is connected to the frame 10, and the second hinge arm 33 is connected to the temple 20. By positioning the hinge shaft 31 in the mounting gap 101, the rotational influence of the first hinge arm 32 and the second hinge arm 33 relative to the hinge shaft 31 can be reduced to a certain extent. The first hinge arm 32 is connected to the frame 10, and the second hinge arm 33 is connected to the temple 20. The connection methods include, but are not limited to, screw connection, snap connection, and plug connection, which ensures both the connection between the frame 10 and the temple 20 and the ability of the temple 20 to rotate relative to the frame 10.
[0080] Furthermore, in an embodiment of the present invention, the hinge structure 30 further includes a hinge cover 34 covering the inside of the mounting gap 101. This not only improves the aesthetics of the mounting gap 101, but also shields and protects the connection position between any two of the hinge shaft 31, the first hinge arm 32, and the second hinge arm 33. At the same time, it also shields and protects the electrical connector 50.
[0081] The hinge cover 34 is rotatably connected to the hinge shaft 31, which can effectively reduce the influence of the hinge cover 34 on the movement of the hinge shaft 31, the first hinge arm 32 and the second hinge arm 33, and at the same time, achieve reliable assembly of the hinge cover 34.
[0082] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
