Description

Technical Field

[0001] The present application relates to wearable devices, and in particular to a head-mounted device bracket and a head-mounted device. Background Art

[0002] A head-mounted display (HMD) is a type of virtual display worn on the head, also known as a glasses-like display or portable theater. Because glasses-like displays resemble glasses and are designed to display video images from audio and video players on a large screen, they are often called video glasses.

[0003] Among them, the mixed reality (Augmented Reality, AR) glasses in the head-mounted devices can realize many functions. They can be regarded as a miniature mobile phone. By tracking the eyeballs to achieve trajectory, they can determine the user's current state and activate the corresponding functions.

[0004] Because AR glasses are relatively heavy, relying solely on the bridge of the nose for support can easily cause them to shake during wear, making them unstable. Therefore, AR glasses are equipped with a fixed forehead support to assist in supporting the glasses and prevent pressure from being concentrated on the bridge of the nose. However, due to different head shapes among different users, the forehead support often cannot ensure stable wear of AR glasses. Summary of the Invention

[0005] The invention aims to solve the problem that the existing head-mounted devices cannot meet the needs of different users with different head shapes for stable wearing.

[0006] The present application provides a head-mounted device bracket that can adapt to different users' head shapes and ensure stable wearing.

[0007] A head-mounted device bracket, used for holding a head, comprising:

[0008] frame;

[0009] Multiple head supports, each of which is detachably mounted on one side of the frame, the head supports being used to press against the outside of the head, each head support corresponding to a different head shape; and

[0010] A limiting structure, wherein the head support is connected to the frame body in a limiting manner through the limiting structure.

[0011] The present application provides a head-mounted device.

[0012] A head-mounted device comprises a display module for displaying scene content experienced by a user in real time and the above-mentioned head-mounted device bracket, wherein the display module is mounted on the bracket.

[0013] It can be seen from the above technical solution that this application has at least the following advantages and positive effects:

[0014] The head-mounted device described above, by providing multiple detachably connected head supports on the frame, can accommodate the different head shapes of different users. Therefore, the head-mounted device support, on the one hand, increases the contact area between the head-mounted device and the user's head, dispersing pressure. On the other hand, by using multiple head supports, the angle between the head support and the housing support can be adjusted and adapted to the angle of the user's head, ensuring complete and stable contact between the head support and the head, thereby ensuring the stability of the head-mounted device when worn.

[0015] Furthermore, the head mounted device support is provided with a limiting structure, which enables the head support to be engaged with the frame to limit the position of the head support and the frame. By engaging the limiting structure with the head support, a detachable connection between the head support and the frame can be easily achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of this disclosure will be more comprehensive and complete, and will fully convey the concepts of the example embodiments to those skilled in the art. The accompanying drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the figures indicate identical or similar parts, and thus repeated descriptions thereof will be omitted.

[0040] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of this specification.

[0041] The head-mounted device of this embodiment includes a head-mounted device bracket and a display module. The display module is mounted on the head-mounted device bracket. The head-mounted device can be used in a variety of fields, such as gaming, film, education, military, medical, enterprise, and e-commerce, and the application fields of the head-mounted device are not limited here. In addition, the head-mounted device can be 3D glasses, virtual reality (VR) glasses, mixed reality (AR) glasses, etc.

[0042] Specifically, in this embodiment, the head-mounted device is described using AR glasses as an example, and other embodiments are not further described. AR glasses allow the wearer to see a scene that is a combination of virtual images and real life. AR glasses can perform many functions and can be thought of as a miniature mobile phone. By tracking the eyeballs to determine the user's current state, it can activate the corresponding function.

[0043] See also Figure 1 and Figure 2The head-mounted device of this embodiment includes a head-mounted device support 1, a display module 2, and a power supply 3. The display module 2 is mounted on one end of the head-mounted device support 1, and the power supply 3 is located on the other end of the head-mounted device support 1. For ease of description, it is now specified that the display module 2 is mounted on the front end of the head-mounted device support 1, and the power supply 3 is located on the rear end of the head-mounted device support 1.

[0044] Display module 2 is mounted on the front end of the head-mounted device bracket 1. Display module 2 is used to display the scene content experienced by the user in real time, showing the images and scenes experienced by the wearer of the AR glasses. There can be one or more display modules 1, and the number of display modules 1 can be designed accordingly according to different needs. The number of display modules 1 is not limited here.

[0045] In this embodiment of the head-mounted device, power supply 3 is located at the rear end of the head-mounted device frame 1, opposite the display module 1. Power supply 3 can be a battery. The power supply and display module 1 are located at opposite ends of the head-mounted device frame 1, respectively, ensuring a relatively balanced weight. Therefore, when the head-mounted device of this embodiment is worn, the weight is evenly distributed around the head, avoiding concentrated pressure on the forehead and nose bridge, ensuring a comfortable wearer and enhancing the user experience.

[0046] See also Figure 2 The head mounted device support 1 of this embodiment includes a frame 10 and a head support 20 .

[0047] The frame 10 is used to hold the head and bear the primary weight of the AR glasses. The display module 2 is mounted on the frame 10. The frame 10 forms a wearing area for the head. The frame 10 can be ring-shaped or headband-shaped, with its shape adapting to the head shape and meeting ergonomic design requirements. The frame 10 distributes the weight of the AR glasses, maximizing their wearer stability.

[0048] Specifically, in this embodiment, the frame 10 may be comprised of multiple interconnected parts. The frame 10 includes a main housing 11 and a housing cover 13. The main housing 11 defines a receiving cavity 15, which accommodates the electronic components of the display module. Alternatively, when the head support 20 is positioned at the back of the head, the receiving cavity 15 may also accommodate the electronic components of the power module.

[0049] Multiple head supports 20 are detachably mounted on one side of the frame 10. The head supports 20 are used to press against the outside of the head, and each head support 20 corresponds to a head of a different shape.

[0050] The head support 20 can be detachably mounted on the front of the frame 10 near the forehead, or it can be split into two parts and detachably mounted on either side of the frame 10 near the ears, or it can be detachably mounted on the rear end of the frame 10 near the back of the head. Furthermore, the head support 20 can be a curved plate that fits the head at the corresponding position, thereby providing a more comfortable fit.

[0051] In this embodiment, the head support 20 is a forehead support that is detachably mounted on the frame 10 near the forehead to alleviate the pressure on the nose bridge caused by the heavy weight of the frame 10, as the electronic components of the frame 10 are mainly concentrated at the front end.

[0052] Therefore, multiple head supports 20 are designed to correspond to different forehead shapes. Based on the forehead inclination, forehead inclination surface, and vertical height from the eyeballs of different head shapes, multiple forehead supports of different heights and matching angles are designed. Users can choose the appropriate forehead support model that matches their forehead shape and size, and then install it on the frame 10 of the head-mounted device support.

[0053] The head-mounted device bracket of this embodiment can be replaced with a head bracket 20 that is adapted to the user, so that the head bracket 20 can better contact and press the head. On the one hand, it can ensure that the head bracket 20 is in stable contact with the head. On the other hand, it can ensure that the head bracket 20 can disperse the force between the frame 10 and the head, avoid excessive pressure on the bridge of the nose, and improve the wearing comfort of the above-mentioned head-mounted device.

[0054] See also Figure 3 and Figure 4 The main shell 11 and the shell cover 13 cooperate to form a receiving groove 14 for accommodating one end of the head support 20. The surface of the main shell 11 is a platform structure 111, and the shell cover 13 is mounted on the platform structure 111 of the main shell 11. The platform structure 111 defines a first receiving groove 112, and the shell cover 13 defines a second receiving groove 131 on the side facing the platform structure 111 of the main shell 11. The first receiving groove 112 and the second receiving groove 131 mate with each other to form the receiving groove 14. Furthermore, the opening 141 of the receiving groove 14 faces inwardly of the wearing area.

[0055] It is understandable that in other embodiments, the opening direction of the receiving groove 14 may also be other directions. For example, the opening direction of the receiving groove 14 may also be along a direction perpendicular to the platform structure 111 .

[0056] See also Figure 4, and a notch 132 is provided on the opening side of the shell cover 13 and the second receiving groove 131. When the head support 20 is received in the receiving groove, the transition portion 23 of the head support 20 is located at the opening of the receiving groove, and the notch 132 can avoid the transition portion 23. The width of the notch 132 is equal to the thickness of the transition portion 23, so when the head support 20 is received in the receiving groove, the transition portion 23 of the head support 20 can be flush with the side of the main shell 11, as shown in FIG. Figure 5 shown.

[0057] See also Figure 4 The head support 20 includes a plate body 21 and a connecting portion 22 provided at the end of the plate body 21. The connecting portion 22 is used to connect with the frame body 10. The shape and thickness of the receiving groove are adapted to the connecting portion 22 of the head support 20.

[0058] The plate 21 is a curved plate that adapts to the shape of the head. It accommodates a variety of forehead shapes. It can accommodate the forehead inclination, forehead slope, and vertical height from the eyeball of a variety of individual head shapes. The plates 21 of multiple head supports 20 can be designed with a variety of different heights and angles.

[0059] A cushion can also be placed on the side of the head support 20 closest to the head to mitigate the impact of sudden head movements on the device, further improving wearing stability and comfort. One side of the cushion fits snugly against the head support 20, while the other side is a curved surface adapted to the corresponding head position. The cushion can be made of latex or sponge.

[0060] The head support 20 also includes a transition portion 23. The transition portion 23 is disposed between the connecting portion 22 and the plate 21. The transition portion 23 is flanked by curved side edges 231. The curved side edges 231 smoothly transition from the connecting portion 22 to the plate 21, thereby evenly distributing the pressure exerted on the plate 21 to the connecting portion 22 and, in turn, to the entire frame 10.

[0061] Specifically, in this embodiment, the connecting portion 22 is perpendicular to the transition portion 23. The shape of the head support 20 in this embodiment facilitates the smooth transmission of pressure on the plate 21 to the connecting portion 22 and then to the frame body 10.

[0062] In other embodiments, the connecting portion 22 may also be formed by extending along the extending direction of the transition portion 23. The entire head support 20 is approximately a straight line structure. The head support 20 is designed in different shapes according to different usage requirements.

[0063] Specifically, in this embodiment, the head-mounted device bracket further includes a limiting structure 30. The head bracket 20 is connected to the frame 10 via the limiting structure 30. The limiting structure 30 enables the head bracket 20 to engage with the frame 10 to limit the position of the head bracket 20 and the frame 10. Therefore, the head bracket 20 is engaged with the frame 10 via the limiting structure 30, achieving an engaging connection and convenient operation. It is understood that the head bracket 20 can also be detachably connected by binding, bolting, or the like.

[0064] Specifically in this embodiment, the limiting structure 30 includes a limiting link 31 , a rotating shaft 32 and a first elastic member 33 .

[0065] The retaining structure 30 is housed within the receiving cavity 15 of the main housing 11. Two opposing lugs 16 are provided on the inner sidewall of the main housing 11. Each lug 16 has a through hole. The ends of the rotating shaft 32 extend through the through holes, allowing the rotating shaft 32 to be rotatably connected to the main housing 11.

[0066] One end of the limiting link 31 is provided with an axis hole 311. One end of the limiting link 31 is rotatably mounted on the rotating shaft 32 through the axis hole 311. In addition, the end of the limiting link 31 connected to the rotating shaft 32 is provided with a bent portion 312. The bent portion 312 is rotatably mounted on one end of the rotating shaft 32.

[0067] The limit link 31 is provided with a snap-fit portion 313. The snap-fit portion 313 is snap-fitted with the head support 20. The limit link 31 rotates around the rotation axis 32. Specifically in this embodiment, the snap-fit portion 313 is a stop post. The main housing 11 is provided with a through hole 113. Figure 6 A slot 24 is formed on the connecting portion 22 of the head support 20. The stop post passes through the through hole and engages with the slot 24 of the head support 20. To facilitate the insertion of the stop post through the through hole 113 and the slot 24, the outer wall of the stop post is rounded. The cross-section of the stop post is elliptical. Furthermore, the through hole 113 and the slot 24 are slightly larger than the cross-section of the stop post.

[0068] The first elastic member 33 is sleeved on the rotating shaft 32. The first elastic member 33 is located at the other end of the rotating shaft 32 relative to the curved portion 312. A rotary arm is provided at each end of the first elastic member 33. The rotary arms are a first rotary arm 331 and a second rotary arm 332.

[0069] Please also see Figure 7 A support plate 34 is fixedly mounted on the inner sidewall of the main housing 11. The support plate 34 is positioned below the limiting link 31. The first swing arm 331 is pressed against the support plate 34 and is limited in position by the support plate 34. It is understood that the support plate 34 can also be an integral structure with the sidewall of the main housing 11.

[0070] The second rotary arm 332 is limited on the limiting link 31. Specifically, a through hole 314 is provided on the limiting link 31. The end of the second rotary arm 332 is passed through the through hole 314 to be connected to the limiting link 31 in a limiting manner.

[0071] The head-mounted device bracket also includes a button 40. The button 40 abuts against the other end of the limit link 31. Pressing the button 40 drives the limit link 31 to rotate about the rotation axis 32. The other end of the limit link 31 is provided with a boss 315, and the button 40 is drivingly connected to the boss 315.

[0072] The limiting link 31 rotates, driving the second swing arm 332 to rotate, so that the first elastic member 33 undergoes elastic deformation. When the limiting link 31 rotates to the support plate 34, the limiting link 31 rotates to the maximum position, at which time the limiting link 31 and the support plate 34 are in contact. Figure 8 The limiting link 31 is provided with an avoidance groove 317 for avoiding the second swing arm 332. When the limiting link 31 is rotated to the maximum position, the second swing arm 332 is accommodated in the avoidance groove 317.

[0073] The first elastic member 33 undergoes elastic deformation, so that the engaging portion 313 is separated from the head support 20 , and the first elastic member 33 recovers its elastic deformation, so that the engaging portion 313 is engaged and connected with the head support 20 .

[0074] Furthermore, the height of the boss 315 matches the height of the button 40. When the button 40 is pressed by an external force, the limit link 31 can be rotated to its maximum position. When the first elastic member 33 recovers its elastic deformation, the boss 315 cooperates with the button 40 to keep the limit link 31 horizontal, and the stop post can remain engaged with the slot 24 of the head support 20.

[0075] Furthermore, the limiting link 31 is provided with a slightly protruding stop 316. When the limiting link 31 and the head support 20 are engaged with each other, the contact surface between the limiting link 31 and the main housing 11 is the top surface of the stop 316, thereby reducing the contact area between the limiting link 31 and the main housing 11 and facilitating rotation of the limiting link 31.

[0076] See also Figure 3 and Figure 4, a second elastic member 35 is provided on the side of the receiving groove 14 away from the opening 141. The second elastic member 35 pushes the head support 10 at one end of the head support 10. Specifically, the main shell 11 is provided with a second elastic member 35 on the side of the opening 141 of the first receiving groove 112. The second elastic member 35 pushes the head support 20 at one side of the head support 20. When the head support 20 is fixed in the receiving groove 14, the second elastic member 35 is compressed and deformed. When the head support 20 is disengaged from the engagement connection with the frame body 10, the second elastic member 35 restores the elastic deformation, causing the head support 20 to pop out from the receiving groove 14. The opening of the receiving groove 14 faces the inner side of the wearing area, and the head support 20 pops out toward the wearing area.

[0077] Furthermore, there may be multiple second elastic members 35. Each of the multiple second elastic members 35 abuts against the head support 20. Specifically, two second elastic members 35 are arranged side by side within the receiving groove 14. This not only increases the elastic thrust on the head support 20, but also balances the force applied to the connecting portion 22 of the head support 20, making the ejection of the head support 20 more stable and reliable.

[0078] Furthermore, the main housing 11 has a guide groove 114 on one side of the first receiving groove 112 for receiving the second elastic member 35. The second elastic member 35 extends and retracts along the guide groove 114. The guide groove 114 extends from the outside of the receiving groove 14 to the inside of the receiving groove 14. As the second elastic member 35 retracts and retracts within the guide groove 114, the guide groove 114 acts as a position limiter for the second elastic member 35, preventing it from moving during the retraction process and affecting the normal ejection of the head support 20.

[0079] The second elastic member 35 can specifically be a compression spring, such as a metal compression spring or a plastic compression spring. The elastic member can also be an air spring, or even a rubber member with good elastic restoring force.

[0080] In other embodiments, the opening of the receiving slot 14 can be oriented perpendicular to the platform structure 111, allowing the head support 20 to be ejected perpendicular to the platform structure 111. Therefore, the head support 20 also changes shape accordingly to allow the plate 21 of the head support 20 to contact the head. Specifically, the shape and placement of the head support 20 in this embodiment can facilitate the transmission and distribution of stress applied to the head support 20.

[0081] It is understood that the frame 10 can also be of other structures. The main shell 11 and the shell cover 13 of the frame 10 can also be an integrated structure, as long as a receiving slot 14 is provided on the frame 10.

[0082] Now, in combination with the specific usage method of the head-mounted device bracket of this embodiment, its structure is described. The second elastic member 35 is fixed on the main shell 11, the shell cover 13 is fixed on the main shell 11, the button 40 is limited in the through hole of the shell cover 13, one swing arm of the first elastic member 33 is fixed on the support plate 34, and the other swing arm of the first elastic member 33 is fixed on the limiting link 31. The main coil spring of the first elastic member 33 is fixed on the rotating shaft 32. The limiting link 31 has a boss at one end in contact with the button 40, and the limiting link 31 has an axis hole 311 at one end fixed to the rotating shaft 32, and the rotating shaft 32 is fixed in the limiting axis hole 311 of the main shell 11.

[0083] When the head support 20 is inserted into the receiving groove 14 formed by the mating surface between the main shell 11 and the shell cover 13, the engaging portion 313 of the limiting link 31 extends into the receiving groove 14 through the through hole 113 of the main shell 11. When the head support 20 is pushed into the position where the engaging portion 313 is located in the receiving groove 14, the front end of the connecting portion 22 of the head support 20 pushes the engaging portion 313 downward out of the receiving groove 14 and pushes the limiting link 31 to rotate, causing the first elastic member 33 to elastically deform. The head support 20 continues to be pushed into the receiving groove 14. When the engaging portion 313 of the head support 20 passes above the engaging portion 313 of the limiting link 31, the engaging portion 313 of the limiting link 31 is extended into the engaging portion 24 of the head support 20 by the elastic restoring force of the first elastic member 33, thereby limiting the connection between the head support 20 and the limiting structure 30.

[0084] When the user needs to replace the head bracket 20 with another model, the previously installed head bracket 20 needs to be removed first. When removing the head bracket 20, it is necessary to press the button 40. The button 40 pushes the limit link 31 to rotate around the rotating shaft 32, and the limit link 31 drives the stop column to move downward together. When the stop column is disengaged from the card slot 24 of the head bracket 20, the second elastic member 35 pushes the head bracket 20 to pop out to the outside of the receiving slot. The user can remove the previously installed head bracket 20 and replace it with a head bracket 20 of another model. Thereafter, the process of installing and disassembling the head bracket 20 is repeated according to the above process, and different head brackets 20 of different models are adjusted according to the usage needs of different users.

[0085] The head-mounted device support of this embodiment is designed with a variety of head supports 20 of different heights and matching angles based on the forehead inclination and the vertical height of the forehead inclination surface from the eyeballs of different head shapes. Users can select the appropriate head support 20 model that matches their forehead shape and size, and then insert it into the receiving slot of the frame body 10. When a different model of head support 20 is needed, the user can press a button to automatically eject the already installed head support 20, and then replace it with another suitable head support 20.

[0086] The head-mounted device bracket of this embodiment mainly uses the elasticity generated by the elastic recovery effect after the first elastic part and the second elastic part are deformed by force, and cooperates with the moving limiting link to limit or bounce the head bracket 20. Therefore, the user can simply and quickly replace the head bracket 20 to meet the matching of individual differences, and the operation is convenient.

[0087] The head support 20 of the head-mounted device support of this embodiment is accommodated in the receiving groove, and then the stop column of the limit link is engaged with the head support 20 to limit the position. The fixing method is simple and convenient. In addition, the price of the first elastic member and the second elastic member are low, and the weight is less than 0.1g, which will not have a significant impact on the weight of the head-mounted device support. In addition, the button, the limit link, and the head support 20 are all made of plastic material with a density of 1.2g / cm 3 , the cost is extremely low, the processing is simple, and the structural strength is high. The motion mechanism of the limit structure is simple and efficient, the force transmission is direct, and the structure size is small, which saves more space and has high stability in use.

[0088] It is understood that in other embodiments, please refer to Figure 9 、 Figure 10 and Figure 11 The limiting structure includes elastic arms 61 provided on both sides of the head support 60 and cams 63 provided on the elastic arms 61. A fixing groove is provided on the frame, and the cam can be engaged with the fixing groove.

[0089] Specifically, taking advantage of the high elasticity of plastic itself, slits 622 are provided on both sides of the connecting portion 62 of the head bracket 60. The slits 622 are provided along the movement direction of the connecting portion 62. The head bracket 60 forms an elastic arm 61 on one side of the slit 622. A cam 63 is provided on the elastic arm 61. Extrusion of the cam 63 can cause the elastic arm 61 to contract relative to the inner side of the slit 622, thereby making the elastic arm 61 elastic. A fixing groove 644 is provided on the inner side wall of the receiving groove 64. The cam 63 can be engaged and connected with the fixing groove 644. When the connecting portion 62 of the head bracket 60 is inserted into the receiving groove 64, when the cam of the head bracket 60 hits the inner side wall of the receiving groove 64, the cam 63 deforms the elastic arm 61, and the cam 63 retracts into the receiving groove 64. The head support 60 can continue to be pushed into the receiving groove 64. When the cam 63 of the head support 20 is pushed to the fixing groove 644, due to the restorability of the elastic arm 61 itself, the cam 63 is pushed back to the natural position, thereby driving the head support 60 to be limited to the predetermined position.

[0090] When the head bracket 60 needs to be replaced, pull the head bracket 60 outward with force. The cam 63 of the head bracket 60 is squeezed by force to squeeze the elastic arm 61 to shrink and deform into the inside of the slit 622, leaving the fixing groove 644, and the head bracket 60 can be taken out to replace the new head bracket 60. The subsequent operation method is the same as above.

[0091] It is understood that in other embodiments, please refer to Figure 12 、 Figure 13 , the opening 641 of the receiving groove 64 can also be oriented in a direction perpendicular to the platform structure 611. The head bracket 60 can then be loaded and unloaded in a direction perpendicular to the platform structure 611. Similarly, the cam 63 on the elastic arm 61 can be engaged with the fixing groove 644. When the head bracket 60 needs to be replaced, the head bracket 60 is pulled outward with force. The cam 63 of the head bracket 60 is pressed by the force to squeeze the elastic arm 61 toward the inside of the slit 622, shrinking and deforming, leaving the fixing groove 644, and the head bracket 60 can be taken out and replaced with a new head bracket 60.

[0092] Although the present application has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present application can be embodied in various forms without departing from the spirit or essence of the present application, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
