Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to a mask for a head-mounted display device and a head-mounted display device. Background Art

[0002] With the development of near-eye technology, head-mounted display devices (HMDs), such as VR and AR devices, are widely used in both work and personal environments. A HMD typically consists of a main unit and a mask connected to the main unit. When a user wears the HMD, the mask fits tightly against the user's face, creating a sealed space and enhancing the user's sense of immersion.

[0003] To improve wearing comfort, the mask adheres to the user's face using a flexible body, such as sponge or foam. Currently, this body is supported by a bracket, which is fixed to the main unit via magnets. This creates a hard contact. Due to the limited deformation capability of the flexible body, the mask is difficult to adapt to different facial shapes, resulting in localized pressure or light leakage, and a poor user experience. Summary of the Invention

[0004] In order to solve the above technical problems, the present application provides a mask for a head-mounted display device and a head-mounted display device.

[0005] In a first aspect, the present application provides a mask for a head-mounted display device, comprising:

[0006] A face-fitting component, comprising a support bracket and a facial cushion disposed on the support bracket;

[0007] The mounting frame includes a main support and a side support that forms a preset angle with the main support;

[0008] a cantilever, rotatably connected to the side bracket via a first rotating shaft, and rotatably connected to the support bracket via a second rotating shaft, capable of rotating toward or away from the main bracket, wherein both the first rotating shaft and the second rotating shaft extend in the vertical direction of the main bracket;

[0009] When the head-mounted display device is worn, the up and down directions of the main bracket are vertical directions, the facial buffer pad is compressed to drive the support bracket to produce elastic deformation, and drive the cantilever to rotate in the direction close to the main bracket.

[0010] Optionally, two side brackets are provided, and the two side brackets are respectively located on both sides of the main bracket in the left and right directions, and form a U-shaped structure with the main bracket;

[0011] The cantilever is rotatably arranged on each of the side brackets.

[0012] Optionally, in the left-right direction of the main support, the cantilevers on the two side supports are spaced apart by a preset distance.

[0013] Optionally, the cantilever is C-shaped, and both ends of the cantilever are rotatably connected to the upper side and the lower side of the supporting bracket in the up and down direction of the main bracket through the second rotating shaft.

[0014] Optionally, the support bracket is provided with two matching pieces on the upper side and the lower side thereof, and the matching pieces have shaft holes for the second rotating shaft to extend into.

[0015] Optionally, in the left-right direction of the main bracket, the two matching pieces located on the upper side of the supporting bracket are symmetrically arranged and are both relatively close to the center position of the supporting bracket;

[0016] The two matching pieces located on the lower side of the support bracket are symmetrically arranged and are both relatively close to the center position of the support bracket.

[0017] Optionally, the main bracket is provided with two through holes corresponding to the display module;

[0018] The support bracket is annular in shape, and the space formed by the support bracket covers the two through holes. The facial buffer pad is arranged along the circumference of the support bracket.

[0019] Optionally, the supporting bracket is arc-shaped as a whole and protrudes towards the main bracket.

[0020] Optionally, the face-sticking assembly further includes a light-shielding member, which is connected between the main bracket and the supporting bracket, and is arranged around the two through holes.

[0021] Optionally, the shading member is a shading cloth.

[0022] In a second aspect, the present application provides a head-mounted display device, comprising a mask of the head-mounted display device provided in the first aspect.

[0023] The technical solution provided by the embodiments of the present application has the following advantages compared with the prior art:

[0024] The support bracket of the face-fitting component is connected to the side bracket of the mounting frame through a cantilever, the cantilever is rotatably connected to the side bracket through a first rotating shaft, and the cantilever is rotatably connected to the support bracket through a second rotating shaft. The first rotating shaft and the second rotating shaft both extend in the up and down directions of the main bracket. In this way, when the mask is worn, the facial cushion can be deformed when under pressure, and can drive the support bracket to produce elastic deformation. The support bracket can move relative to the mounting frame through the cantilever, so that the mask can adapt to the face shapes of different users, and the facial cushion can fit the faces of different users, avoiding problems of local compression or light leakage, and improving user experience.

[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0039] like Figures 1 to 6 As shown, an embodiment of the present application provides a mask for a head-mounted display device, including a face-contact component 1, a mounting frame 2 and a cantilever 3.

[0040] The face-fitting assembly 1 includes a support bracket 11 and a facial cushion 12 mounted on the support bracket 11. The mounting frame 2 includes a main bracket 21 and a side bracket 22 positioned at a predetermined angle relative to the main bracket 21. The cantilever 3 is pivotally connected to the side bracket 22 via a first pivot 32. The cantilever 3 is pivotally connected to the support bracket 11 via a second pivot 33, allowing it to rotate toward or away from the main bracket 21. Both the first and second pivots 32 and 33 extend vertically along the main bracket 21.

[0041] When the head-mounted device is worn, the up and down directions of the main bracket 21 are vertical directions, and the facial buffer pad 12 is compressed to drive the support bracket 11 to produce elastic deformation, and drive the cantilever 3 to rotate in the direction close to the main bracket 21.

[0042] Understandably, the support bracket 11 of the face-fitting component 1 is connected to the side bracket 22 of the mounting frame 2 through the cantilever 3, the cantilever 3 is rotatably connected to the side bracket 22 through the first rotating shaft 32, and the cantilever 3 is rotatably connected to the support bracket 11 through the second rotating shaft 33. The first rotating shaft 32 and the second rotating shaft 33 both extend in the up and down directions of the main bracket 21. In this way, when the mask is worn, the facial cushion 12 can be deformed when under pressure, and can drive the support bracket 11 to produce elastic deformation. The support bracket 11 can move relative to the mounting frame 2 through the cantilever 3, so that the mask can adapt to the face shape of different users, so that the facial cushion 12 can fit the face of different users, avoid local compression or light leakage problems, and improve user experience.

[0043] It should be noted that the cantilever 3 can swing relative to the side bracket 22 in the front-to-back direction of the main bracket 21. The front-to-back direction, left-to-right direction, and top-to-bottom direction of the main bracket 21 are perpendicular to each other. When the head-mounted display device is worn, the top-to-bottom direction of the main bracket 21 is the vertical direction. In this case, the front-to-back direction of the main bracket 21 refers to the front-to-back direction of the user, and the left-to-right direction of the main bracket 21 refers to the left-to-right direction of the user.

[0044] like Figure 1 and Figure 2As shown, in some embodiments, two side brackets 22 are provided, and the two side brackets 22 are respectively located on both sides of the main bracket 21 in the left and right directions, and form a U-shaped structure with the main bracket 21. A cantilever 3 is rotatably provided on each side bracket 22.

[0045] It can be understood that supporting the support bracket 11 by the two side brackets 22 and the cantilevers on the two side brackets 22 can improve the stability of the support bracket 11 and the mounting frame 2 after assembly, so that when the head-mounted display device is worn, the support bracket 11 as a whole can stably produce elastic deformation when under pressure, thereby allowing the facial cushion 12 to better adapt to the faces of different users.

[0046] Thus, when the head-mounted device is worn, the middle portions of the facial cushion 12 and the support bracket 11 in the left-right direction of the main bracket 21 are compressed and move toward the main bracket 21. The facial cushion 12 and the support bracket 11 on either side of the support bracket 11 move toward each other. During this process, the cantilever 3 rotates toward the main bracket 21. When the mask is removed, the force of the support bracket 11 returning to its original shape causes the cantilever 3 to rotate away from the main bracket 21.

[0047] Furthermore, the cantilevers 3 on the two side brackets 22 are spaced apart by a predetermined distance in the left-right direction of the main bracket 21. It is understood that the two cantilevers 3 do not intersect in the left-right direction of the main bracket 21, which not only facilitates assembly of the mask but also prevents interference between the two cantilevers 3 during rotation.

[0048] For example, in a specific implementation, referring to Figure 2 The above-mentioned cantilever 3 is provided with two, and the two cantilevers 3 are respectively rotatably connected to the two side brackets 22, and the two cantilevers 3 are respectively rotatably connected to the two sides of the supporting bracket 11 in the left and right directions of the main bracket 21.

[0049] Alternatively, in another specific implementation, four cantilevers may be provided, with two cantilevers rotatably provided on each side bracket, and the two cantilevers on each side bracket are rotatably connected to the upper and lower sides of the support bracket, respectively. In this case, the cantilevers are arc-shaped, and the two cantilevers on each side bracket form a C-shaped structure.

[0050] Alternatively, in other embodiments, only one of the two side brackets is provided with a cantilever. In this case, the cantilever on the side bracket is rotationally connected to one side of the support bracket in the left-right direction of the main bracket via a second rotating shaft, while the other side of the support bracket is connected to the other side bracket. The connection between the other side of the support bracket and the other side bracket is a rotational connection or a sliding connection. When the rotational connection is used, the support bracket can rotate relative to the main bracket in the front-to-back direction of the main bracket; when the sliding connection is used, the support bracket can slide relative to the main bracket in the front-to-back direction of the main bracket.

[0051] Reference Figure 1 and Figure 2 The facial cushion 12 is located on the side of the support frame 11 facing away from the main frame 21, which facilitates the fit of the facial cushion 12 against the user's face. In some embodiments, the facial cushion 12 is made of sponge, which is lightweight and elastic, enhancing the comfort of wearing the mask. Alternatively, in other embodiments, the facial cushion 12 can be made of foam.

[0052] like Figure 2 and Figure 3 As shown, the main bracket 21 has two through holes 211 corresponding to the display module (not shown). The support bracket 11 is annular, and the space formed by the support bracket 11 covers the two through holes 211. The facial cushion 12 is arranged along the circumference of the support bracket 11.

[0053] As can be understood, the support bracket 11 is annular, and the space formed by the support bracket 11 covers the two through-holes 211. Therefore, when the mask is worn, the user's eyes correspond to the two through-holes 211, allowing for a better view of the image displayed by the display module. Furthermore, the facial cushion 12 is arranged along the circumference of the support bracket 11, so that when the mask is worn, the facial cushion 12 surrounds the user's eyes, improving wearing comfort.

[0054] Furthermore, the support bracket 11 is generally curved and convex toward the main bracket 21. This configuration allows the support bracket 11 to better conform to the user's facial shape when the mask is worn, helping the facial cushion 12 to better fit the user's face and prevent light leakage. Furthermore, when the mask is worn, the middle portion of the support bracket 11 in the left-right direction is pressed toward the main bracket 21, while the portions on either side of the support bracket 11 in the left-right direction approach each other, thereby clamping the user's head and ensuring that the facial cushion 12 better fits the user's face.

[0055] Furthermore, the face-sticking assembly 1 further includes a light shielding member 13 , which is connected between the main bracket 21 and the supporting bracket 11 , and is disposed around the two through holes 211 .

[0056] It can be understood that by providing the shading member 13 , the shading member 13 surrounds the two through holes 211 and is connected between the main bracket 21 and the supporting bracket 11 , thereby achieving the shading effect.

[0057] For example, in a specific implementation, the shading member 13 is selected as a black cloth. For example, a black cloth material is selected. The black cloth is light in weight, which can achieve the lightweight of the mask, and has a soft texture and does not affect the movement of the support bracket 11 relative to the main bracket 21.

[0058] It should be noted that the above-mentioned blackout cloth is folded and arranged between the main bracket 21 and the support bracket 11, that is, the blackout cloth has redundancy and can be expanded or folded as the support bracket 11 moves, thereby avoiding the blackout cloth from being torn when the support bracket 11 moves.

[0059] In summary, compared with the prior art in which the support bracket uses plastic to connect the main bracket and achieve shading, the mask uses a cantilever 3 to support the face-fitting component 1, and uses a blackout cloth to achieve shading between the support bracket 11 and the main bracket 21. The overall weight of the mask is reduced by about 5g.

[0060] like Figure 2 and Figure 4 As shown, in some embodiments, the cantilever 3 is C-shaped, and both ends of the cantilever 3 are rotatably connected to the upper and lower sides of the support bracket 11 in the up and down directions of the main bracket 21 through the second rotating shaft 33.

[0061] It can be understood that the cantilever 3 is rotatably connected to the side bracket 22 through the first rotating shaft 32, and the two ends of the cantilever 3 are respectively rotatably connected to the upper and lower sides of the support bracket 11 through the second rotating shaft 33. The movable connection between the support bracket 11 and the side bracket 22 can be achieved through one cantilever 3, and the synchronization is good.

[0062] Specifically, refer to Figure 4 The cantilever 3 includes a C-shaped cantilever body 31 , the second rotating shaft 33 is provided at both ends of the cantilever body 31 , and the first rotating shaft 32 is provided in the middle position of the cantilever body 31 .

[0063] Further, refer to Figure 2 In order to improve the stability of the cantilever 3 when it rotates relative to the side bracket 22, the side bracket 22 has extension plates on both sides of the support bracket 11 in the upper and lower directions. Each extension plate is provided with a socket 221 for the first rotating shaft 32 to extend into, that is, the two ends of the first rotating shaft 32 on the cantilever 3 are respectively inserted into the sockets 221 on the two extension plates.

[0064] Furthermore, the cantilever body 31 can produce a certain elastic deformation when the opposite side bracket 22 rotates, thereby further improving the effect of the mask adapting to different face shapes. Specifically, the cantilever body 31 is in the shape of a thin plate, and the specific thickness is set according to actual needs and is not specifically limited here.

[0065] like Figure 5 and Figure 6 As shown, the support bracket 11 is provided with two fittings 111 on the upper side and the lower side thereof. The fittings 111 have shaft holes 1111 for the second rotating shaft 33 to extend into.

[0066] It can be understood that by cooperating with the axial hole 1111 on the mating part 111 and the second rotating shaft 33 on the cantilever 3, not only a rotational connection is achieved, so that the support bracket 11 can rotate relative to the cantilever 3, but also the cantilever 3 can support the support bracket 11, thereby realizing the mating connection between the support bracket 11 and the mounting frame 2.

[0067] Furthermore, in the left-right direction of the main bracket 21, the two mating pieces 111 located on the upper side of the support bracket 11 are symmetrically arranged and are both relatively close to the center position of the support bracket 11. The two mating pieces 111 located on the lower side of the support bracket 11 are symmetrically arranged and are both relatively close to the center position of the support bracket 11.

[0068] It is understandable that the support bracket 11 is divided into two parts in the left-right direction of the main bracket 21, and each part is provided with a matching piece 111 on both the upper and lower sides. The two matching pieces 111 located on the upper side of the support bracket 11 are relatively close to the center position of the support bracket 11 in the left-right direction of the main bracket 21, and are quite far away from the end position of the support bracket 11 in the left-right direction of the main bracket 21; the two matching pieces 111 located on the lower side of the support bracket 11 are relatively close to the center position of the support bracket 11 in the left-right direction of the main bracket 21, and are quite far away from the end position of the support bracket 11 in the left-right direction of the main bracket 21. In this case, the cantilever 3 needs to be inserted into the shaft hole 1111 of the matching piece 111 through the second rotating shaft 33. At this time, the length of the cantilever 3 in the left-right direction of the support bracket 11 is relatively long, which is conducive to improving the stability of the cantilever 3 supporting the support bracket 11.

[0069] The present application also provides a head-mounted display device, which includes the mask of the head-mounted display device described above. The head-mounted display device has the technical effects of the mask in the above embodiment, which will not be described in detail here.

[0070] It should be noted that the above-mentioned head-mounted display device can be VR glasses, MR glasses, etc., and there is no specific limitation here.

[0071] The head-mounted display device also includes a display module, which is mounted in the through-hole. Two display modules are provided, one mounted in each through-hole. When wearing the mask, the user can view the images displayed by the display modules with both eyes.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
