[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0061] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "telescopic", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0062] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections. A person of ordinary skill in the art will understand the specific meanings of the above terms in the present invention in specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics may be combined in any appropriate manner in any one or more embodiments or examples.

[0063] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0064] Some embodiments of the present application involve a head-mounted display device, which may be an AR head-mounted display device or a VR head-mounted display device. When a user puts on or takes off the head-mounted display device, there is a risk that the head-mounted display device may fall. Because the head-mounted display device is equipped with a camera, there is a risk that the camera may be damaged by collision.

[0065] Therefore, in some embodiments of the present application, a camera mechanism is provided, which is installed on a head-mounted display device. When the head-mounted display device falls, the camera can be protected from damage, and the camera's shooting range is not blocked when the wearer is in a normal wearing state.

[0066] In some embodiments of the present application, taking AR glasses as an example, Figure 1 As shown, the head-mounted display device includes a camera mechanism, a lens portion and a temple portion, and the temple portion is connected to the side of the lens portion.

[0067] In some embodiments of the present application, the head-mounted display device is a framed head-mounted display device, the lens part includes a frame 310 and two left and right lenses mounted on the frame 310; the temple part includes two left and right temples 320, and the two temples 320 are respectively connected to the left and right sides of the frame 310.

[0068] In some embodiments of the present application, the head-mounted display device is a frameless head-mounted display device, the lens part includes two left and right lenses and an intermediate connecting piece that connects the two lenses into one; the temple part includes two left and right temples 320, and the two temples 320 are respectively connected to the left and right sides of the whole formed by the two lenses.

[0069] In some embodiments of the present application, Figures 2 to 16 As shown, a camera mechanism includes a camera module 100 and a sensing module 200. The sensing module 200 is electrically connected to the camera module 100 and is used to detect a user's wearing signal to control the action of the camera module 100.

[0070] The camera module 100 includes a camera body 110, a housing 120, and a power assembly. The camera body 110 is mounted in the housing 120. The power assembly is used to drive the camera body 110 to extend and retract relative to the housing 120.

[0071] When the camera body 110 is in the working state, the camera body 110 is driven to extend out of the housing 120 .

[0072] When the camera body 110 is in a non-working state, the camera body 110 is driven to be retracted into the housing 120 .

[0073] In some embodiments of the present application, the direction in which the camera body 110 extends or retracts relative to the housing 120 is defined as a telescopic direction.

[0074] Specifically, abnormal conditions such as falling are included in the non-working state. Therefore, in abnormal conditions such as falling, the camera body 110 is retracted into the housing 120, so that the camera body 110 is protected and prevented from being damaged by collision.

[0075] Based on the wearer's wearing signal detected by the sensing module 200, the sensing module 200 can control the power assembly. When the sensing module 200 detects that the wearer is wearing the head-mounted display device, the sensing module 200 controls the camera body 110 to extend out of the housing 120. When the sensing module 200 detects that the head-mounted display device is not being worn, the sensing module 200 controls the camera body 110 to retract into the housing 120.

[0076] In some embodiments of the present application, Figure 15 As shown, the power assembly includes a drive component and a telescopic assembly. The fixed portion of the telescopic assembly is connected to the housing 120, and the movable portion of the telescopic assembly is connected to the camera body 110. The drive component drives the telescopic assembly to extend and retract, thereby driving the movable portion to move relative to the fixed portion, thereby driving the camera body 110 to move relative to the housing 120.

[0077] The design of the telescopic assembly can be determined according to the extension and retraction stroke of the camera body 110.

[0078] In some embodiments of the present application, Figure 14 As shown, the fixing portion includes a first rack 131. The first rack 131 is arranged in the housing 120 and extends along the telescopic direction.

[0079] like Figure 12 As shown, the moving portion includes a second rack 132. The second rack 132 is extended along the telescopic direction and is arranged on the camera body 110.

[0080] The telescopic assembly further includes a first telescopic assembly and a second telescopic assembly.

[0081] like Figure 10 As shown, the first telescopic assembly includes a first frame 133, a first gear 134 and a third rack 135. The first gear 134 is rotatably connected to the first frame 133. The third rack 135 is extended along the telescopic direction and is arranged on the first frame 133.

[0082] like Figure 11 As shown, the second telescopic assembly includes a second frame 136, a second gear 137 and a fourth rack 138. The second gear 137 is rotatably connected to the second frame 136. The fourth rack 138 is extended and arranged on the second frame 136 along the telescopic direction.

[0083] like Figure 5 、 Figure 7 As shown, the first gear 134 is engaged with the first rack 131 and the fourth rack 138 to drive the second frame 136 to move along the telescopic direction.

[0084] The second gear 137 is engaged with the second rack 132 and the third rack 135 to drive the camera body 110 to move along the extension direction.

[0085] In some embodiments of the present application, a accommodating portion 121 is formed in the shell 120, and the first frame 133, the second frame 136 and the camera body 110 are sequentially arranged in the accommodating portion 121, with the camera body 110 located at the innermost side, the first frame 133 located at the outermost side, and the second frame 136 located between the camera body 110 and the first frame 133.

[0086] Under the power transmission of the first telescopic assembly and the second telescopic assembly, the camera body 110 is able to telescope relative to the housing 120 through the power transmission of the first frame 133 and the second frame 136 .

[0087] The staggered design of the first gear 134 and the second gear 137 allows for synchronous extension and retraction. This allows the first frame 133, the second frame 136, and the camera body 110 to retract and retract simultaneously relative to the housing 120, rather than one by one. This improves operational efficiency. Furthermore, the extension and retraction of the first frame 133, the second frame 136, and the camera body 110 relative to the housing 120, ensures a greater range of movement for the camera body 110 relative to the housing 120.

[0088] In some other embodiments of the present application, for the case where the required extension stroke of the camera body 110 is shorter, the telescopic assembly includes a first gear 134, a first frame 133 and a second frame 136. The first gear 134 is rotatably connected to the first frame 133. The fixed portion includes a first rack 131. The first rack 131 is extended along the extension direction and is arranged in the shell 120. The movable portion includes a fourth rack 138. The fourth rack 138 is extended along the extension direction and is arranged on the second frame 136. The camera body 110 is connected to the second frame 136. Under this transmission mode, the first gear 134 is engaged with the first rack 131 and the fourth rack 138 to drive the camera body 110 to move along the extension direction with the second frame 136.

[0089] That is, in this embodiment, the second frame 136 and the camera body 110 are integrally connected. The extension and retraction of the second frame 136 directly drives the extension and retraction of the camera body 110. This eliminates the need for a rack and pinion transmission structure between the second frame 136 and the camera body 110, and allows the camera body 110 to extend and retract. In some embodiments of the present application, multiple telescopic assemblies are provided. These multiple telescopic assemblies are spaced apart along the circumference of the camera body 110, and are disposed between the camera body 110 and the housing 120.

[0090] In some embodiments of the present application, Figure 16 As shown, the driving component includes a motor 141 and a stud 142. The output end of the motor 141 is coaxially connected to the stud 142 as a whole.

[0091] A threaded hole is formed on the first frame 133 . The threaded hole is formed on the first frame 133 along the extension direction of the camera body 110 relative to the housing 120 .

[0092] The stud 142 is threadedly connected to the threaded hole. The first frame 133 is configured so that when the motor 141 drives the stud 142 to rotate via its output shaft, the threaded hole and the threaded engagement of the stud 142 allow the first frame 133 to move only in the direction of extension and contraction of the camera body 110, moving away from or toward the housing 120, but not to rotate. For example, a sliding guide structure can be provided on the first frame 133 and the housing 120, with the guide direction parallel to the direction of elevation of the first frame 133, so that the first frame 133 can only move relative to the housing 120 and not rotate.

[0093] In some embodiments of the present application, when the motor 141 rotates along the first direction, the first bracket 133 moves along the stud to move away from the housing 120 .

[0094] When the motor 141 rotates along the second direction, the first bracket 133 moves along the stud to approach the housing 120 .

[0095] Specifically, when the motor 141 rotates in the first direction, the first frame 133 gradually moves away from the housing 120, that is, gradually extends relative to the housing 120. The first gear 134 engages with the first rack 131 and the fourth rack 138. The first gear 134 drives the fourth rack 138 to move in the extension direction, thereby driving the second frame 136 to move relative to the first frame 133 in a direction away from the housing 120. In this way, when the first frame 133 extends relative to the housing 120, the second frame 136 is also driven to extend relative to the first frame 133.

[0096] As the second frame 136 extends relative to the first frame 133, the second gear 137 moves with the second frame 136, and the second gear 137 engages with the second rack 132 and the third rack 135, thereby driving the camera body 110 to extend relative to the second frame 136. This achieves the coordinated extension of the first frame 133 relative to the housing 120, the second frame 136 relative to the first frame 133, and the camera body 110 relative to the second frame 136.

[0097] When the motor 141 rotates in the second direction, the first frame 133 gradually approaches the housing 120, that is, the first frame 133 gradually retracts relative to the housing 120, and the first gear 134 engages with the first rack 131 and the fourth rack 138. The first gear 134 drives the fourth rack 138 to move in the retraction direction, thereby driving the second frame 136 to move relative to the first frame 133 in a direction approaching the housing 120. In this way, when the first frame 133 is retracted relative to the housing 120, the second frame 136 is also retracted relative to the first frame 133.

[0098] During the retraction of the second frame 136 relative to the first frame 133, the second gear 137 moves with the second frame 136. The second gear 137 engages with the second rack 132 and the third rack 135. The second gear 137 drives the second rack 132 to move in the retraction direction, thereby driving the camera body 110 to retract relative to the second frame 136. This achieves the coordinated retraction of the first frame 133 relative to the housing 120, the second frame 136 relative to the first frame 133, and the camera body 110 relative to the second frame 136.

[0099] In some embodiments of the present application, the sensing module 200 includes a sensor 210 and a controller (not shown), which is integrated on a mainboard 220 of the head-mounted display device. The sensor 210 is electrically connected to the controller, and the driving component is electrically connected to the controller.

[0100] Specifically, the motor 141 is electrically connected to the controller.

[0101] Specifically, the sensor 210 is used to detect whether the head-mounted display device is in a wearing state. When an abnormal state such as falling occurs, the sensor 210 can feedback a non-wearing state signal to the controller, thereby controlling the rotation of the motor 141 through the controller, thereby controlling the retraction of the camera body 110.

[0102] In some embodiments of the present application, a through portion 311 is provided on the lens portion (eg, on the lens frame 310 ), and the camera body 110 can be extended or retracted relative to the through portion 311 .

[0103] Specifically, the through portion 311 may be in the form of a through hole.

[0104] Specifically, the penetration portion 311 corresponds to the position of the camera body 110 .

[0105] In some embodiments of the present application, the head-mounted display device includes two camera mechanisms. The two camera modules 100 are respectively connected to the left and right ends of the frame 310. The two sensor modules 200 are respectively connected to the two temples 320.

[0106] Two through-portions 311 are provided, and the two through-portions 311 are formed on the left and right ends of the mirror frame 310 respectively.

[0107] By setting up a sensing module 200, it is possible to detect whether the camera is in a worn state; when the sensing module 200 detects that the camera is in a worn state, the power component drives the camera body 110 to extend out of the shell 120, thereby ensuring that the camera body 110 is in a working state and is not blocked; when the sensing module 200 detects that the camera is in a non-worn state, including abnormal states such as falling, the power component drives the camera body 110 to be retracted relative to the shell 120 into the shell 120, thereby ensuring that the camera body 110 is in a non-working state and the camera body 110 is retracted into the shell 120 and will not be damaged when it falls.

[0108] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
