Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a head-mounted device 10 according to an embodiment of the present application, fig. 2 is an exploded structural diagram of the head-mounted device 10 in fig. 1, and fig. 3 is a structural diagram of a wearing support 100 in fig. 2.

As shown in fig. 1 to 2, a head-mounted device 10 provided in an embodiment of the present application may include: a wearing support 100, an optical lens 200 and an external hanging module 300. Wherein, the wearing support 100 can be worn on the head of the user. The optical lens 200 and the plug-in module 300 may be disposed on the wearing bracket 300. In this embodiment, the plug-in module 300 may be used to implement the function of augmented reality or virtual reality environment in front of the eyes of the user. Of course, the plug-in module 300 may also be used to implement other functions, such as lighting, shooting, and audio playing.

The wearing bracket 100 may be used to carry the optical lens 200 and the plug-in module 300, so that a user may wear the plug-in module 300 on the head for use. As shown in fig. 3, the wearable mount 100 may include: a frame 110 and legs 120. Wherein the frame 110 may be worn in front of the eyes of the user and the frame 110 may be used for mounting the optical lens 200. The support legs 120 may be disposed at opposite sides of the frame 110, and the support legs 120 may be worn at both sides of the head of the user for installing the plug-in module 300. The frame 110 and the leg 120 may be pivotally connected by a hinge or pivot such that the leg 120 may be folded relative to the frame 110 to improve portability of the wearable stand 100. Of course, the frame 110 and the legs 120 may also be fixedly connected. In this embodiment, the frame 110 and the legs 120 may be made of rigid materials such as metal, rigid plastic, and rigid rubber, so that the frame 110 and the legs 120 may have certain rigidity, thereby providing a supporting force for the wearing bracket 100 to mount the optical lens 200 and the plug-in module 300. Accordingly, the materials of the frame 110 and the support legs 120 may be the same or different, and the materials of the frame 110 and the support legs 120 may be selected according to actual requirements, which is not limited herein.

The frame 110 may be worn in front of the eyes of the user and the frame 110 may be used to mount the optical lens 200. As shown in fig. 3, the frame 110 may include: a frame 111 and a nose pad 112. The frame 111 can be worn in front of the eyes of the user, and the frame 111 can be used for mounting the optical lens 200. The nose pad 112 may be connected to the frame 111, and the nose pad 112 may be used to contact with a nose of a user to support the frame 111, the optical lens 200, and the plug-in module 300. The legs 120 may be disposed on two opposite sides of the frame 111, and the legs 120 may be fixedly connected to the frame 111. In this embodiment, the frame 111 may be made of a rigid material such as metal, hard plastic, hard rubber, etc., so that the frame 111 not only has a certain rigidity, but also has a certain elastic deformation capability, so as to facilitate the assembly of the frame 111 and the optical lens 200.

The frame 111 may be provided with a first sub-frame 1111, a second sub-frame 1112, and a cross member 1113. The first sub-frame 1111 and the second sub-frame 1112 may be disposed at two opposite ends of the cross beam 1113, respectively, and the optical lens 200 may be mounted on both the first sub-frame 1111 and the second sub-frame 1112. For example, the first sub-frame 1111 and the second sub-frame 1112 may be annularly disposed, and the optical lens 200 may be disposed in a space surrounded by the first sub-frame 1111 and the second sub-frame 1112, and fixedly connected to the first sub-frame 1111 and the second sub-frame 1112 by gluing, snapping, or interference fit, so as to achieve the assembly of the frame 111 and the optical lens 200. The nose pad 112 may be disposed between the first sub-frame 1111 and the second sub-frame 1112, and connected to the first sub-frame 1111 and the second sub-frame 1112, respectively, so that the nose pad 112 supports the frame 111. The first sub-frame 1111 and the second sub-frame 1112 may also be symmetrically disposed, and a side of the first sub-frame 1111 facing away from the cross beam 1113 may be used to connect with the supporting leg 120, and a side of the second sub-frame 1112 facing away from the cross beam 1113 may also be used to connect with the supporting leg 120, so that the supporting leg 120 may be disposed on two opposite sides of the frame 111.

In some embodiments, the frame 111 may be provided with only the first subframe 1111 and the second subframe 1112, and the first subframe 1111 and the second subframe 1112 may be an integral structure. In some embodiments, the frame body 111 may also be provided with only the first sub-frame 1111 for installing one optical lens 200, that is, the first sub-frame 1111 is the entire frame body 111. In addition, in some embodiments, when the head-mounted device 10 does not need to mount the optical lens 200, the frame 111 may be provided with only the cross beam 1113, and the opposite ends of the cross beam 1113 may be used to connect with the legs 120, and the nose pads 112 may be directly connected with the cross beam 1113. The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying a number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Referring to fig. 4 to 7, fig. 4 is another schematic connecting structure of the frame 111 and the leg 120 in fig. 3, fig. 5 is a schematic partial sectional structure of the frame 111 along v-v in fig. 4, fig. 6 is a schematic connecting structure of the frame 111 and the optical lens 200 in fig. 4, and fig. 7 is a schematic partial sectional structure of the frame 111 and the optical lens 200 along vi-vi in fig. 6.

In addition to the aforementioned manner of fixedly connecting the frame 111 and the optical lens 200, in order to improve the versatility of the head-mounted device 10, the frame 111 may be detachably connected to the optical lens 200, so that a user may select the corresponding optical lens 200 to be matched with the head-mounted device 10 according to the requirement. Since the first sub-frame 1111 and the second sub-frame 1112 are symmetrically disposed, only the first sub-frame 1111 will be described as an example. As shown in fig. 4 to 5, the first sub-frame 1111 may be provided with a bearing portion 11111, a guide portion 11112, and a first engaging portion 11113. The bearing part 11111 may be provided with a receiving groove 11101 for mounting the optical lens 200. The guiding portion 11112 may be connected to the bearing portion 11111 and may be used to provide guidance for the installation of the optical lens 200. The first engaging portion 11113 can be disposed in the accommodating groove 11101 and can be used for engaging with the optical lens 200. In this embodiment, after being received by the receiving groove 11101, the optical lens 200 may be engaged with the first engaging portion 11113 in the receiving groove 11101, so as to assemble the optical lens 200 and the first sub-frame 1111. The bearing portion 11111 is configured to be elastically deformed to provide an escape space for the optical lens 200 to escape from the accommodating groove 11101, thereby achieving detachment of the optical lens 200 and the first subframe 1111. In this way, the user can replace the optical lens 200 as needed to improve the versatility of the head-mounted device 10.

The bearing part 11111 may have one end connected to the beam 1113 and the other end connected to the leg 120, and the bearing part 11111 may further be provided with a receiving groove 11101 for mounting the optical lens 200. As shown in fig. 6 to 7, the shape of the accommodating groove 11101 may be adapted to the optical lens 200, and the accommodating groove 11101 may penetrate through the bearing portion 11111 in the thickness direction of the optical lens 200, so that the inner wall of the accommodating groove 11101 may only contact with the edge of the optical lens 200, so that the first engaging portion 11113 in the accommodating groove 11101 is engaged with the optical lens 200. Meanwhile, since the accommodating groove 11101 penetrates the bearing portion 11111 in the thickness direction of the optical lens 200, in order to further limit the optical lens 200 and prevent the optical lens 200 from coming off the accommodating groove 11101 in the thickness direction, the bottom wall of the accommodating groove 11101 may be further provided with a positioning groove 11102, and the shape of the positioning groove 11102 may be adapted to the optical lens 200. In this embodiment, the supporting portion 11111 may be disposed in an arc shape, such that the supporting portion 11111 is recessed to form the receiving groove 11101. Therefore, the arc-shaped structure of the bearing part 11111 can better adapt to the shape of the optical lens 200, and the adaptation degree of the optical lens and the bearing part is improved. In some embodiments, the shape of the bearing portion 11111 may also be adjusted according to design requirements or the shape of the optical lens 200, which is not limited in this embodiment.

When the optical lens 200 occupies the accommodating groove 11101 and is engaged with the first engaging portion 11113, a partial area of the optical lens 200 may be disposed in the positioning groove 11102, that is, the optical lens 200 is accommodated in the positioning groove 11102, so that the displacement of the optical lens 200 in the thickness direction can be limited by the inner sidewall of the positioning groove 11102, and the optical lens 200 is prevented from being displaced or swayed in the thickness direction. In this embodiment, the optical lens 200 may completely occupy the accommodating groove 11101 and the positioning groove 11102, so that the positioning groove 11102 limits the optical lens 200. Of course, the optical lens 200 may only occupy a part of the space of the positioning groove 11102, and only the positioning groove 11102 may limit the position of the optical lens 200. In some embodiments, the first sub-frame 1111 may also be clamped with the optical lens 200 only by the first clamping portion 11113, so as to limit the optical lens 200 without providing the positioning groove 11102.

As shown in fig. 5 to fig. 7, the guiding portion 11112 may be connected to the circumferential side of the bearing portion 11111, and the guiding portion 11112 may extend in the gravity direction X, which may be used to guide the optical lens 200 to be installed, so that the optical lens 200 may slide into the accommodating groove 11101 along the guiding portion 11112 to be engaged with the first engaging portion 11113. For example, the guide portion 11112 may be provided with a guide groove 11103, and the guide groove 11103 may penetrate through the guide portion 11112 in the gravity direction X and communicate with the accommodating groove 11101, so that the optical lens 200 may slide into the accommodating groove 11101 along the guide groove 11103 from the gravity direction X and be engaged with the first engaging portion 11113, thereby achieving the assembly of the optical lens 200 and the first sub-frame 1111.

When the optical lens 200 is received by the receiving groove 11101 and is engaged with the first engaging portion 11113, a partial area of the optical lens 200 may be disposed in the guiding groove 11103, that is, received by the guiding groove 11103, so that the inner sidewall of the guiding groove 11103 may limit the optical lens 200 in the thickness direction of the optical lens 200. So set up, not only can utilize guide way 11103 to improve the assembly accuracy and the convenience of optical lens 200 and first sub-frame 1111, can also utilize guide way 11103 and constant head tank 11102 to cooperate and carry on spacingly to optical lens 200, improve the assembly fastness of optical lens 200 and first sub-frame 1111. In some embodiments, the guiding portion 11112 may also be provided with a guiding member such as a sliding rail or a sliding bar to provide a guiding function for the optical lens 200, only that the optical lens 200 can slide into the accommodating groove 11101 along the guiding portion 11112 from the gravity direction X. The gravity direction X may specifically refer to a direction perpendicular to the thickness direction of the optical lens 200 after the head-mounted device 10 is worn on the head of the user.

The number of the guide parts 11112 may be two, and the two guide parts 11112 may be a first guide part 11112a and a second guide part 11112b, respectively. The first guide part 11112a and the second guide part 11112b may be connected to the same side of the carrier part 11111, and the first guide part 11112a and the second guide part 11112b are disposed at an interval. For example, the first guide part 11112a may be located at an end of the bearing part 1111 connected to the cross beam 1113, and the second guide part 11112b may be located at an end of the bearing part 1111 connected to the leg 120, so that the first guide part 11112a and the second guide part 11112b may be spaced apart. The optical lens 200 may be disposed between the first guide portion 11112a and the second guide portion 11112b, and may slide into the receiving groove 11101 along the guide groove 11103 of the first guide portion 11112a and the second guide portion 11112b from the gravity direction X to occupy the receiving groove 11101 and engage with the first engaging portion 11113.

In addition, since the first guide portion 11112a is located at the end of the bearing portion 11111 connected to the cross beam 1113 and is disposed adjacent to the second sub-frame 1112, the first guide portion 11112a can also be used to mount the nose pad 112, so that the nose pad 112 is connected to the first sub-frame 1111 and the second sub-frame 1112 respectively. Not only can further improve the assembly accuracy and the convenience of optical lens 200 and supporting portion 1111 through setting up two guide parts 11112, can also utilize guide groove 11103 on two guide parts 11112 to cooperate with constant head tank 11102 and carry on spacingly to optical lens 200, further improve the assembly fastness of optical lens 200 and first sub-frame 1111. In some embodiments, the first sub-frame 1111 may also be provided with only the carrying portion 11111 and the first engaging portion 11113, and no guiding portion 11112 is provided, only the optical lens 200 can be disposed in the accommodating groove 11101 to engage with the first engaging portion 11113.

As shown in fig. 5 to fig. 7, the first engaging portion 11113 may be disposed on an inner wall of the receiving groove 11101, such that the optical lens 200 can be engaged with the first engaging portion 11113 after being received by the receiving groove 11101. The first engaging portion 11113 may be disposed on two opposite sides of the accommodating groove 11101, that is, the first engaging portion 11113 may be disposed on two opposite sidewalls of the accommodating groove 11101, and the first engaging portion 11113 may be disposed with a groove 11113a. When the optical lens 200 slides into the receiving groove 11101 along the guiding groove 11103 in the gravity direction X and is received by the receiving groove 11101, a partial area of the optical lens 200 can be inserted into the grooves 11113a on two opposite sides of the receiving groove 11101, that is, the partial area is received by the grooves 11113a, so as to be engaged with the first engaging portion 11113. Therefore, the inner wall of the groove 11113a can be used to limit the optical lens 200, so as to prevent the optical lens 200 from coming out of the accommodating groove 11101 in the gravity direction X, and thus the optical lens 200 and the first sub-frame 1111 can be assembled. In this embodiment, the first engaging portion 11113 and the supporting portion 11111 can be an integral structure, that is, the first engaging portion 11113 can be a part of the inner sidewall of the accommodating groove 11101. The side wall of the accommodating groove 11101, in which the first engaging portion 11113 is disposed, may be connected to the bottom wall of the guide groove 11103, and the two may also be disposed in parallel, so that the optical lens 200 may directly slide into the groove 11113a of the first engaging portion 11113 after sliding into the accommodating groove 11101 along the guide groove 11103, and be engaged with the first engaging portion 11113.

In some embodiments, after the optical lens 200 is received by the receiving groove 11101 and is engaged with the first engaging portion 11113, the first sub-frame 1111 may also be in an elastically deformed state, so that the bearing portion 11111, the first guiding portion 11112a and the second guiding portion 11112b may clamp the optical lens 200 to improve the assembling stability of the optical lens 200 and the first sub-frame 1111. In some embodiments, the accommodating groove 11101 may also have only one inner sidewall provided with the first engaging portion 11113, and only the first engaging portion 11113 is required to be capable of engaging with the optical lens 200 to limit the movement of the optical lens 200. In the embodiment of the present application, all directional indicators (such as up, down, left, right, front, rear \8230;) are used only to explain the relative positional relationship between the components, the motion situation, etc. at a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

The optical lens 200 can be disposed in the accommodating groove 11101 and engaged with the first engaging portion 11113. As shown in fig. 5 to 7, the opposite sides of the optical lens 200 may be provided with second engaging portions 210, and the second engaging portions 210 may be provided with protrusions 210a. After the optical lens 200 slides into the receiving groove 11101 along the guiding groove 11103 in the gravity direction X, the protrusions 210a on opposite sides of the optical lens 200 can be inserted into the grooves 11113a on opposite sides in the receiving groove 11101, so that the first engaging portion 11113 and the second engaging portion 210 can be engaged with each other, thereby assembling the optical lens 200 and the first sub-frame 1111. When the optical lens 200 needs to be detached, the first sub-frame 1111 can be elastically deformed, so that the protrusion 210a can be withdrawn from the groove 11113a, thereby releasing the first engaging portion 11113 and the second engaging portion 210. The optical lens 200 can exit from the accommodating groove 11101 along the guiding groove 11103, so that the optical lens 200 and the first sub-frame 1111 can be detached. The shape of the protrusion 210a can be adapted to the shape of the groove 11113a, so as to avoid a gap between the protrusion 210a and the inner wall of the groove 11113a, which may cause the optical lens 200 to shake due to external force.

Further, the optical lens 200 may be made of one or more transparent or translucent materials such as glass, plastic, etc. The optical lens 200 may also be made of one or more of transparent material, semi-transparent material, opaque material, etc. for a specific light transmission effect. The optical lens 200 may be a vision correction lens made of one or more of convex lens, concave lens, and the like, and of course, other types of lenses or functional lenses (such as myopia lens, flat lens, anti-glare lens, colored lens, and the like) or functional membranes (such as antireflection film, polarization film, light filter, electrochromic film, photochromic film, and the like) may be further disposed in the vision correction lens. In some embodiments, the type of the optical lens 200 may not be limited to the above type, and the specific type may be selected according to the user's requirement, which is not limited herein.

In this way, when the optical lens 200 needs to be assembled, the optical lens 200 can slide into the accommodating groove 11101 along the guide groove 11103 from the gravity direction X. In this process, the protrusions 210a on the opposite sides of the optical lens 200 can slide along the bottom wall of the guide groove 11103 and abut against the bottom wall of the guide groove 11103, so that the first sub-frame 1111 can be elastically deformed to provide an escape space for the optical lens 200 to slide in. When the protrusion 210a slides to the groove 11113a in the receiving groove 11101, the first sub-frame 1111 may be restored to a state before being deformed, and the protrusion 210a may be inserted into the groove 11113a, so that the first engaging portion 11113 may be engaged with the second engaging portion 210, thereby achieving the assembly of the optical lens 200 and the first sub-frame 1111. When the optical lens 200 needs to be detached, the first sub-frame 1111 may be elastically deformed under the snapping of a user to provide an avoidance space, so that the protrusion 210a may be withdrawn from the groove 11113a, the first engaging portion 11113 and the second engaging portion 210 are released from the engaging state, and the optical lens 200 may be withdrawn from the accommodating groove 11101 along the guide groove 11103, thereby detaching the optical lens 200 and the first sub-frame 1111. In this way, the optical lens 200 and the first subframe 1111 can be detachably connected, so that the user can replace the optical lens 200 as required, thereby improving the versatility of the head-mounted device 10.

In addition, since the second sub-frame 1112 and the first sub-frame 1111 are symmetrically disposed, the second sub-frame 1112 and the first sub-frame 1111 have the same structure and can be detachably connected to the optical lens 200, and the specific structure and connection method can be referred to the first sub-frame 1111 as described above, which is not repeated herein.

Referring to fig. 8, fig. 8 is a schematic sectional view of another portion of the frame 111 and the optical lens 200 of fig. 7 along vi-vi.

In some embodiments, the positions of the groove 11113a and the bump 210a can be interchanged. As shown in fig. 8, the first engaging portion 11113 may be provided with a protrusion 210a, and the second engaging portion 210 may be provided with a groove 11113a, so that the first engaging portion 11113 and the second engaging portion 210 can still realize the detachable connection between the optical lens 200 and the first sub-frame 1111 through the groove 11113a and the protrusion 210a, and the specific assembling manner and the disassembling manner thereof are the same as or similar to those of the above embodiments, and are not repeated herein. In addition, in some embodiments, when the bearing portion 11111 is only provided with the receiving groove 11101, the first engaging portion 11113 may also be disposed on the bottom wall of the receiving groove 11101, and the first engaging portion 11113 may also be provided with a groove 11113a, and the opening of the groove 11113a may be slightly smaller than the protrusion 210a of the second engaging portion 210. In this way, when the optical lens 200 occupies the accommodating groove 11101, the protrusion 210a can abut against the inner wall of the groove 11113a, so that the bearing portion 11111 is elastically deformed, thereby providing an avoiding space for the protrusion 210a to be inserted into the groove 11113a. After the protrusion 210a is inserted into the groove 11113a, the bearing portion 11111 may return to the non-deformed state or remain in the deformed state, so that the protrusion 210 may be caught in the groove 11113a, thereby assembling the optical lens 200 and the first sub-frame 1111. Accordingly, when the optical lens 200 needs to be detached, the bearing portion 11111 may be elastically deformed under the action of the user, so as to provide an escape space for the protrusion 210a to exit the groove 11113a, so that the protrusion 210a can exit from the groove 11113a, thereby detaching the optical lens 200 and the first sub-frame 1111.

Referring to fig. 9 to 11, fig. 9 is a schematic structural view of the wearable support 100 in fig. 3 from another perspective, fig. 10 is a schematic structural view of the nose pad 112 in fig. 9, and fig. 11 is a partial enlarged view of a portion a in fig. 9.

The nose pads 112 may be connected to the first sub-frame 1111 and the second sub-frame 1112, respectively, and the nose pads 112 may be used for supporting the frame 111, the legs 120, the optical lens 200, and the plug-in module 300. As shown in fig. 9 to 10, the nose pad 112 may be provided with a first nose pad 1121 and a second nose pad 1122. The first nose pad 1121 may be connected to a side of the first sub-frame 1111 near the second sub-frame 1112, the second nose pad 1122 may be connected to a side of the second sub-frame 1112 near the first sub-frame 1111, and the first nose pad 1121 and the second nose pad 1122 may be spaced apart from each other. In the present embodiment, the first nose pad 1121 and the second nose pad 1122 may have a height difference H in the gravity direction X, and the first nose pad 1121 and the second nose pad 1122 may further have an elastic deformation capability. So set up, when the landing leg 120 is at the installation external hanging module 300 for when the relative both sides gravity of framework 111 is unbalanced, first nose holds in the palm 1121 and second nose holds in the palm 1122 can utilize difference in height H, guarantees that the pressure that first nose holds in the palm 1121 and second nose holds in the palm 1122 to user's nose is unanimous, improves the comfort level of wearing that the user wore head mounted device 10. The gravity direction X may be specifically a direction in which the first nose pad 1121 and the second nose pad 1122 are arranged on the frame 111, that is, a direction perpendicular to the thickness direction of the optical lens 200.

The first nose pad 1121 may be provided with a first flexible piece 11211 and a first deformable piece 11212. Wherein the first flexible member 11211 can be adapted to contact the nose of the user. One end of the first deforming member 11212 may be connected to the first sub-frame 1111, and the other end may be connected to the first flexible member 11211, and the first deforming member 11212 may have an elastic deforming capability, so that the first flexible member 11211 may move relative to the first sub-frame 1111 by using the deformation of the first deforming member 11212, so as to achieve the adjustability of the first flexible member 11211, thereby improving the fitting range of the nose pad 112. In this embodiment, the first flexible member 11211 may be a nose pad made of a flexible skin-friendly material such as plastic, silicone, or rubber. The first deforming member 11212 may be a metal strip made of a metal material, so that the first deforming member 11212 has a certain rigidity to support the first flexible member 11211 and a certain elastic deformation capability to facilitate the movement of the first flexible member 11211 relative to the first sub-frame 1111. In some embodiments, the first deforming member 11212 may not be limited to a metal strip, and the specific material and shape thereof may be set according to the requirement, and only the first deforming member 11212 may have an elastic deformation capability.

The second nose pad 1122 may be provided with a second flexible piece 11221 and a second deformation piece 11222. Wherein the second flexible member 11221 may be adapted to contact the nose of the user and the second flexible member 11221 may be spaced apart from the first flexible member 11211. A second deformation 11222 may be connected at one end to the second subframe 1112 and at the other end to a second flexible member 11221. Correspondingly, the second deformation member 11222 may also be spaced apart from the first deformation member 11212, and the second deformation member 11222 may have an elastic deformation capability, so that the second flexible member 11221 may move relative to the second sub-frame 1112 by using the deformation of the second deformation member 11222, so as to achieve the adjustability of the second flexible member 11221, thereby improving the fitting range of the nose pad 112. In this embodiment, the second flexible member 11221 may be a nose pad made of a flexible skin-friendly material such as plastic, silicone or rubber. The second deformation member 11222 may be a metal strip made of a metal material, so that the second deformation member 11222 has a certain rigidity to support the second flexible member 11221 and a certain elastic deformation capability to facilitate the movement of the second flexible member 11221 relative to the second subframe 1112. In some embodiments, the second deformation member 11222 may not be limited to a metal strip, and the specific material and shape thereof may be set according to the requirement, and it is only necessary that the second deformation member 11222 has the elastic deformation capability.

As shown in fig. 11, the first nose pad 1121 and the second nose pad 1122 have a height difference H in the gravity direction X, so that when the user wears the head-mounted device 10, the higher one of the heights may first contact with the nose of the user and be elastically deformed so that the height thereof may be consistent with the lower one of the heights, and the lower one of the heights may later contact with the nose of the user. In this way, when the gravity on the opposite sides of the frame 111 is unbalanced, the height difference H between the first nose pad 1121 and the second nose pad 1122 can make the pressure exerted by the first nose pad 1121 and the second nose pad 1122 on the nose of the user consistent, so as to avoid the problem that the impression is formed on the nose of the user by the first nose pad 1121 or the second nose pad 1122 due to the excessive pressure on one side, and improve the comfort level of wearing the head-mounted device 10 by the user. In this embodiment, since the first and second

flexible members

11211 and 11221 are adapted to contact the nose of the user, the first and second

flexible members

11211 and 11221 may have a height difference H in the gravity direction X, so that the pressure applied by the first and second

flexible members

11211 and 11221 on the nose of the user can be kept uniform. The specific numerical value of the height difference H can be obtained by calculating the moment balance according to the data obtained by the weight and the center of gravity position of the head-mounted device 10, the support position of the nose pad 112, the equivalent resultant force position of the leg 120, the three-dimensional size of the wearable support 100, and the elastic modulus of the wearable support, which is not limited in this embodiment.

When the structures of the first flexible member 11211 and the second flexible member 11221 are the same, the structures of the first deformation member 11212 and the second deformation member 11222 are also the same, and the first deformation member 11212 and the second deformation member 11222 can also be symmetrically disposed with respect to the direction of gravitational force X, it is possible to make the first flexible member 11211 and the second flexible member 11221 have a height difference H in the direction of gravitational force X by changing the connection position of the first flexible member 11211 and the first deformation member 11212, and the connection position of the second flexible member 11221 and the second deformation member 11222. For example, the first deforming member 11212 may be connected to a middle region of the first flexible member 11211, and the second deforming member 11222 may be connected to an edge region of the second flexible member 11221, so that the first flexible member 11211 and the second flexible member 11221 may have a height difference H in the gravity direction X. In this embodiment, the height of the first flexible member 11211 in the gravity direction X may be higher than the height of the second flexible member 11221 in the gravity direction X, and the connection position of the first flexible member 11211 and the first deformation member 11212 may also not be limited to the middle region, and the connection position of the second flexible member 11221 and the second deformation member 11222 may also not be limited to the edge region, and the specific connection position may be selected according to the value of the height difference H, which is not limited herein. In some embodiments, the first flexible member 11211 and the second flexible member 11221 may have a height difference H in the gravity direction X by designing the first flexible member 11211 and the second flexible member 11221 to have different structures.

In some embodiments, the first deforming member 11212 and the second deforming member 11222 may be configured to provide a height difference H between the first compliant member 11211 and the second compliant member 11221. For example, an end of the first deformation member 11212 connected to the first sub-frame 1111 may be symmetrically disposed with an end of the second deformation member 11222 connected to the second sub-frame 1112, and an end of the first deformation member 11212 connected to the first flexible member 11211 may have a height in the gravity direction X higher than that of an end of the second deformation member 11222 connected to the second flexible member 11221. Meanwhile, the connection position of the first flexible member 11211 and the first deformation member 11212 may be the same as the connection position of the second flexible member 11221 and the second deformation member 11222. In this manner, the height difference H between the first flexible piece 11211 and the second flexible piece 11221 may be formed using the height difference between the end of the first deformation piece 11212 connected to the first flexible piece 11211 and the end of the second deformation piece 11222 connected to the second flexible piece 11221, so that the height of the first flexible piece 11211 in the gravitational direction X may be higher than the height of the second flexible piece 11221 in the gravitational direction X. In this embodiment, the first and second

pliable components

11211, 11221 may be identical in construction.

In some embodiments, the height difference H between the first flexible member 11211 and the second flexible member 11221 can also be obtained by changing the connection position of the first deformation member 11212 and the first sub-frame 1111 and the connection position of the second deformation member 11222 and the second sub-frame 1112. For example, the height of the end of the first deforming member 11212 connected to the first sub-frame 1111 in the gravitational direction X may be higher than the height of the end of the second deforming member 11222 connected to the second sub-frame 1112 in the gravitational direction X. Meanwhile, the connection position of the first flexible member 11211 and the first deformation member 11212 may be the same as the connection position of the second flexible member 11221 and the second deformation member 11222. In this manner, the height difference H between the first flexible piece 11211 and the second flexible piece 11221 may be formed using the height difference between the end of the first deformation piece 11212 connected to the first sub-frame 1111 and the end of the second deformation piece 11222 connected to the second sub-frame 1112, so that the height of the first flexible piece 11211 in the gravitational direction X may be higher than the height of the second flexible piece 11221 in the gravitational direction X. In this embodiment, the first flexible member 11211 and the second flexible member 11221 may have the same structure, and the first deforming member 11212 and the second deforming member 11222 may have the same structure.

In this way, the height of the first flexible piece 11211 in the gravitational direction X can be made higher than the height of the second flexible piece 11221 in the gravitational direction X. When the external hanging module 300 is mounted on the supporting leg 120, so that the frame 111 has a heavy gravity on one side of the second flexible piece 11221, the first flexible piece 11211 can be firstly abutted against the nose of a user during wearing, so that the first deformable piece 11212 is elastically deformed to drive the first flexible piece 11211 to displace, and thus the heights of the first flexible piece 11211 and the second flexible piece 11221 in the gravity direction X are kept consistent. At this point, the second flexible member 11221 may then abut the user's nose to support the head-mounted device 10. That is, the first flexible member 11211 may abut against the nose of the user to share a portion of the weight that the second flexible member 11221 needs to bear, and then support the head-mounted device 10 together by making the second flexible member 11221 abut against the nose of the user, so as to ensure that the pressure applied to the nose of the user by the first flexible member 11211 and the second flexible member 11221 is consistent, improve the wearing comfort of the user, and avoid the problem that the pressure on one side of the second flexible member 11221 is too high to form an indentation on the nose of the user or cause discomfort to the user. Of course, in some embodiments, as the gravity on the two opposite sides of the frame 111 changes, the height of the second flexible piece 11221 in the gravity direction X may also be higher than the height of the first flexible piece 11211 in the gravity direction X, which is not limited in this embodiment.

Referring to fig. 12 to 17 in conjunction with fig. 3, fig. 12 is a schematic connection structure diagram of the frame 111 and the leg 120 in fig. 3 from another perspective, fig. 13 is a schematic connection structure diagram of the frame 111 and the leg 120 in fig. 3, fig. 14 is a partially enlarged view of B in fig. 13, fig. 15 is a schematic structure diagram of the leg main body 121 in fig. 13, fig. 16 is a partially enlarged view of C in fig. 15, and fig. 17 is a schematic structure diagram of the ear hook 122 in fig. 13.

The legs 120 may be disposed on opposite sides of the frame 111, and the legs 120 may be used to mount the plug-in module 300. As shown in fig. 3 and 12 to 13, the leg 120 may be provided with a leg body 121, an ear hook 122, and a connecting member 123. The leg body 121 can be connected to the frame 111, and the ear hook 122 can be disposed at the tail end of the leg body 121 and can move relative to the leg body 121 to adjust the position of the ear hook 122. The connecting member 123 may be disposed on the supporting leg main body 121 and configured to be magnetically connected to the plug-in module 300, so as to assemble the supporting leg 120 and the plug-in module 300. The number of legs 120 may be two, a first leg 12001 and a second leg 12002. The first leg 12001 may be connected to the first sub-frame 1111, and the first leg 12001 may be disposed on a side of the first nose pad 1121 facing away from the second nose pad 1122. The second leg 12002 may be connected to the second sub-frame 1112, and the second leg 12002 may be disposed on a side of the second nose pad 1122 facing away from the first nose pad 1121. Since the height of the first flexible member 11211 in the gravity direction X is higher than the height of the second flexible member 11221 in the gravity direction X, the second leg 12002 may be used for connection with the plug-in module 300. Of course, the first leg 12001 can be used to connect with the plug-in module 300 according to the height design of the first flexible element 11211 and the second flexible element 11221.

One end of the leg main body 121 may be connected to one side of the frame 111, and the leg main body 121 may be worn on the ear of the user to support the head-mounted device 10. As shown in fig. 15 to 16, two opposite sides of the leg body 121 may be provided with sliding grooves 1201, and the sliding grooves 1201 of the two opposite sides may communicate to penetrate the leg body 121. The ear hook 122 can be inserted into the leg body 121 through the sliding groove 1201, and can slide along the sliding groove 1201 relative to the leg body 121. Meanwhile, the leg body 121 may further be provided with a receiving groove 1202 communicated with the sliding groove 1201, and the receiving groove 1202 may be used for receiving the ear hook 122, so that the ear hook 122 may be screwed into or out of the leg body 121, thereby improving the portability of the head-mounted device 10. In this embodiment, the other end of the leg main body 121, that is, the tail end of the leg main body 121, may be bent, so that when the user wears the head-mounted device 10, the tail end of the leg main body 121 may be bent to hug the head of the user, so as to improve the wearing firmness of the head-mounted device 10.

The ear hook 122 may be connected to the leg body 121, and the ear hook 122 may be located at the tail end of the leg body 121, so that the ear hook 122 fits to the ear of the user, and the wearing firmness of the head-mounted device 10 is improved. The ear hook 122 can slide relative to the leg body 121 and be accommodated in the leg body 121, and a distance between one end of the ear hook 121 and the other end thereof can be adjusted, that is, the ear hook 121 itself can be extended and retracted to adjust a length of the ear hook 122, so that a user can adjust a wearing position of the ear hook 122 according to an ear size of the user. As shown in fig. 14 and 17, the ear hook 122 may be provided with a first movable member 1221 and a second movable member 1222. The first movable assembly 1221 can be connected to the leg body 121, and can slide along the sliding slot 1201 relative to the leg body 121 and rotate into or out of the receiving slot 1202. The second movable element 1222 is connected to the first movable element 1221, and can slide relative to the leg body 121 under the driving of the first movable element 1221, and can be screwed into or out of the receiving groove 1202. Meanwhile, the second movable member 1222 may also be displaced in a direction close to or away from the first movable member 1221 to adjust the distance between the first movable member 1221 and the second movable member 1222, so that the distance between both ends of the ear hook 122 is adjustable.

The first movable element 1221 may be provided with a rotating shaft 12211, a first movable element 12212, a first limiting element 12213, and a second limiting element 12214, which are connected to each other. The rotating shaft 12211 can be inserted through the sliding grooves 1201 on two opposite sides of the leg body 121, and can slide along the sliding grooves 1201 relative to the leg body 121, and the rotating shaft 12211 can also rotate relative to the leg body 121. One end of the first movable member 12212 may be disposed in the receiving groove 1202 and fixedly connected to the rotating shaft 121, so that the first movable member 12212 can slide and rotate relative to the leg main body 121 under the driving of the rotating shaft 121, and further rotate into or out of the receiving groove 1202. The first limiting member 12213 may be disposed at one end of the rotating shaft 12211, the second limiting member 12214 may be disposed at the other opposite end of the rotating shaft 12211, and the first limiting member 12213 and the second limiting member 12214 are configured to clamp the leg main body 121, so as to lock the position of the rotating shaft 12211 after the rotating shaft 12211 slides or rotates relative to the leg main body 121, thereby realizing the residence of the first moving member 12212 at different positions. In this embodiment, the first movable member 12212 can be used to contact with the ear of the user after being rotated out of the receiving slot 1202, so as to improve the wearing security of the head-mounted apparatus 10. When the user does not need to use the first movable member 12212, the first movable member 12212 can be rotated into the receiving groove 1202 to improve the portability of the head-mounted device 10.

The outer surface of the rotating shaft 12211 may be provided with a first screw 12201, and at least one of the first limiting member 12213 and the second limiting member 12214 may rotate along the first screw 12201 relative to the rotating shaft 12211 to adjust a distance between the first limiting member 12213 and the second limiting member 12214, so that the first limiting member 12213 and the second limiting member 12214 may clamp the leg main body 121 or release the leg main body 121, thereby locking or moving the rotating shaft 12211. For example, the first limiting member 12213 may be fixedly disposed at one end of the rotating shaft 12211, and the other opposite end of the rotating shaft 12211 may be provided with a first thread 12201. The second limiting member 12214 may be sleeved at the other opposite end of the rotating shaft 12211, and the second limiting member 12214 may be provided with a screw thread matching with the first screw thread 12201, so that the second limiting member 12214 can rotate relative to the rotating shaft 12211 along the first screw thread 12201, thereby achieving adjustment of the distance between the first limiting member 12213 and the second limiting member 12214.

Further, the second limiting member 12214 may be provided with a fixing portion 122141 and a handle 122142. The fixing portion 122141 may be sleeved at the other opposite end of the rotating shaft 12211, and the fixing portion 122141 may be provided with a screw thread matching with the first screw thread 12201, for matching with the first limiting member 12213 to clamp the leg main body 121. The handle 122142 may be disposed on a side of the fixing portion 122141 away from the leg body 121, and may be held by a user, so that the user may drive the fixing portion 122141 to rotate along the first thread 12201 by the handle 122142, thereby improving convenience of use for the user. In some embodiments, the first limiting member 12213 may also be provided with a screw thread matching with the first screw thread 12201 and a handle 122142, like the second limiting member 12214, so that the first limiting member 12213 can also rotate relative to the rotating shaft 12211 to adjust the distance between the first limiting member 12213 and the second limiting member 12214.

With this arrangement, when a user needs to use the ear hook 122, the distance between the first limiting member 12213 and the second limiting member 12214 can be increased by rotating the second limiting member 12214, so that the first limiting member 12213 and the second limiting member 12214 can be released from the leg main body 121. The first movable member 12212 can be rotated out of the receiving slot 1202 by the rotating shaft 121, and can slide or rotate relative to the leg body 121 to adjust to a position adapted to the ear of the user. When the first movable member 12212 is adjusted to a suitable position, a user can rotate the second limiting member 12214 in a reverse direction to reduce a distance between the first limiting member 12213 and the second limiting member 12214, so that the first limiting member 12213 and the second limiting member 12214 can clamp the leg main body 121, and further lock the position of the first movable member 12212, so that the user can use the leg main body conveniently. Accordingly, when the user does not need to use the ear hook 122, as described above, the distance between the first limiting member 12213 and the second limiting member 12214 is first increased to enable the first movable member 12212 to move into the accommodating groove 1202, and then the distance between the first limiting member 12213 and the second limiting member 12214 is decreased to enable the first movable member 12212 to be limited in the accommodating groove 1202, so as to accommodate and hide the first movable member 12212.

The second movable assembly 1222 may be provided with a sliding rod 12221, a second movable member 12222, a third limiting member 12223, and a fourth limiting member 12224. One end of the sliding rod 12221 may be connected to the first movable member 12211, and the other opposite end may be connected to the second movable member 12222. The second movable member 12222 can be displaced by the slide bar 12221 in a direction toward or away from the first movable member 12221 to adjust the distance between the first and second

movable members

12211 and 12222 such that the ear hook 122 can be shortened or lengthened. The third limiting member 12223 and the fourth limiting member 12224 may be disposed on the sliding rod 12221, and the third limiting member 12223 and the fourth limiting member 12224 may be configured to clamp the second movable member 12222, so as to lock the position of the second movable member 12222 after the second movable member 12222 is displaced, thereby realizing the residence of the first movable member 12222 at different positions. In this embodiment, the second movable member 12222 can also be rotated into or out of the receiving slot 1202 by the first movable member 12211, and can slide relative to the leg body 121, so as to adjust the second movable member 12222.

One end of the slide bar 12221 may be inserted into the first movable member 12211, the other opposite end may be inserted into the second movable member 12222, and an outer surface of the slide bar 12221 may be provided with a second thread 12202. The second movable member 12222 may be provided with threads that mate with the second threads 12202 such that the second movable member 12222 can rotate along the second threads 12202 to displace in a direction toward or away from the first movable member 12211 to achieve extension and retraction of the ear hook 122. Meanwhile, the second movable member 12222 may further include a through groove 12203, and a partial region of the sliding rod 12221 may further be disposed in the through groove 12203 and penetrate through two opposite sides of the through groove 12203. The third limiting member 12223 and the fourth limiting member 12224 may be sleeved on the sliding rod 12221, and the third limiting member 12223 and the fourth limiting member 12224 may also be provided with a screw thread matched with the second screw thread 12202, so that the third limiting member 12223 and the fourth limiting member 12224 may rotate relative to the sliding rod 12221 along the second screw thread 12202, thereby achieving an adjustable distance between the third limiting member 12223 and the fourth limiting member 12224. The fourth limiting member 12224 can be disposed in the through groove 12203, so that the third limiting member 12223 and the fourth limiting member 12224 can jointly clamp the second movable member 12222 to lock the position of the second movable member 12222. In this embodiment, the fourth limiting member 12224 may further protrude out of the through groove 12203, so that a user can rotate the fourth limiting member 12224.

With this arrangement, when a user needs to extend or shorten the ear hook 122, the distance between the third limiting member 12223 and the fourth limiting member 12224 can be increased by rotating the third limiting member 12223 and the fourth limiting member 12224, so that the second movable member 12222 can rotate along the second thread 12202, and thus move in a direction close to or away from the first movable member 12212 to adjust the position of the ear-fitting. When the second movable member 12222 is adjusted to a suitable position, a user may rotate the third limiting member 12223 and the fourth limiting member 12224 reversely to reduce a distance between the third limiting member 12223 and the fourth limiting member 12224, so that the third limiting member 12223 and the fourth limiting member 12224 may clamp the second movable member 12222 together, and further lock a position of the second movable member 12222, so that the user may use the device.

Referring to fig. 18, fig. 18 is a partial sectional structure schematic view of the wearing bracket 100 and the external hanging module in fig. 1 along the line 300 VII-VII.

The connecting member 123 may be disposed on the leg body 121, and the connecting member 123 may be magnetically connected to the plug-in module 300, so as to detachably connect the wearing frame 100 and the plug-in module 300. As shown in fig. 18, the connecting member 123 may be embedded in the leg main body 121, and one side of the connecting member 123 may be exposed outside the leg main body 121 and flush with the outer surface of the leg main body 121, so that the connecting member 123 and the plug-in module 300 are magnetically connected. For example, the leg body 121 may be provided with a first mounting groove 1204, the connection member 123 may be disposed in the first mounting groove 1204, and the shape of the first mounting groove 1204 may be adapted to the connection member 123. In this embodiment, the connecting member 123 may be a permanent magnet with magnetic force to achieve the magnetic connection between the leg body 121 and the plug-in module 300. Meanwhile, the number of the connecting pieces 123 may be two, and the two connecting pieces 123 may be arranged along the length direction of the leg main body 121 to limit the position of the external hanging module 300, thereby preventing the external hanging module 300 from rotating relative to the leg main body 121 under the action of external force. In some embodiments, the number of the connecting members 123 is not limited to two, and may be more than one. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

In addition, in order to avoid the connecting member 123 directly exposed outside the leg main body 121 and affecting the appearance fineness of the wearing bracket 100, the leg 120 may further be provided with a shielding member 124, and the shielding member 124 may be covered on the first mounting groove 1204 to shield the connecting member 123. Meanwhile, in order to reduce the process flow, the blocking piece 124 may be integrally formed with the leg body 121, and the connecting piece 123 may be integrally formed with the leg body 121 and the blocking piece 124 by in-mold injection. Of course the shield 124 may also be a separate component.

Accordingly, the plug-in module 300 may be provided with a housing 310, a mating member 320, a trigger 330, a circuit board 340, and a geomagnetic sensor 350. The housing 310 may be used to mount various electronic devices required by the plug-in module 300. The fitting member 320 may be disposed on the housing 310, and may be magnetically connected to the connecting member 123 to assemble the leg body 121 and the plug-in module 300. The trigger 330 may be disposed in the housing 310, and may trigger an electrical signal after the leg body 121 and the plug-in module 300 are connected in place, so as to implement the function of the plug-in module 300. The circuit board 340 and the geomagnetic sensor 350 may be disposed within the housing 310, and the geomagnetic sensor 350 may be disposed on the circuit board 340. The geomagnetic sensor 350 may detect a current position and a facing tilt angle of the add-on module 300 by using a geomagnetic field, so as to achieve a positioning function of the add-on module 300. In this embodiment, the external module 300 may be a smart glasses, and may further include a waveguide and an optical engine. In some embodiments, the plug-in module 300 may also be other functional modules, such as a bluetooth module, a camera module, and the like.

The fitting member 320 may be embedded in the housing 310, and one side of the fitting member 320 may be flush with the outer surface of the housing 310, so that the fitting member 320 and the connecting member 123 are magnetically connected. For example, the housing 310 may be provided with a second mounting groove 311, the fitting member 320 may be disposed in the second mounting groove 311, and the shape of the second mounting groove 311 may be adapted to the fitting member 320. In this embodiment, the engaging element 320 may also be a permanent magnet with magnetic force, so that the engaging element 320 and the connecting element 123 can be magnetically connected to each other, so as to detachably connect the leg body 121 and the plug-in module 300. Meanwhile, the number of the fitting members 320 may also be two, and the two fitting members 320 and the two connecting members 123 may be arranged in one-to-one correspondence. In some embodiments, the connecting element 123 and the engaging element 320 may also be made of a material that can be attracted by magnetic force, such as metal, etc., only that any one of the connecting element 123 and the engaging element 320 can have magnetic force.

Further, in order to improve the magnetic connection between the connecting member 123 and the mating member 320, the leg body 121 may further include a protrusion 1211, and the housing 310 may further include a limiting groove 312. Wherein, the protrusion 1211 may be provided with a first mounting groove 1204 so that the connector 123 may be disposed on the protrusion 1211. The second mounting groove 311 may be disposed on the bottom wall of the limiting groove 312, such that the fitting member 320 may be disposed in the limiting groove 312. Thus, after the connecting member 123 and the mating member 320 are magnetically connected, the protrusion 1211 can occupy the position-limiting groove 312, so that the protrusion 1211 can be limited by the inner wall of the position-limiting groove 312, thereby improving the magnetic connection firmness between the leg body 121 and the plug-in module 300. In some embodiments, it is also possible that the leg body 121 is provided with a limiting groove 312, and the housing 310 is provided with a projection 1211. In addition, the connecting element 123 may not be disposed on the protrusion 1211, and the fitting element 320 may not be disposed in the retaining groove 312, and the protrusion 1211 may occupy the retaining groove 312 only after the connecting element 123 and the fitting element 320 are magnetically connected.

The trigger 330 may be disposed within the housing 310, and the trigger 330 may be connected to the circuit board 340. The triggering member 330 may be a hall sensor, which may be used to detect the magnetic field change of the connecting member 123 and the mating member 320, so as to trigger a corresponding electrical signal according to the magnetic field change of the connecting member 123, and transmit the electrical signal to the circuit board 340, so that the plug-in module 300 may implement a corresponding function according to the electrical signal. For example, the triggering element 330 may trigger the electrical signal when the connecting element 123 and the mating element 320 are magnetically connected to each other, so that the plug-in module 300 may implement functions such as automatic power-on, music playing, and voice broadcasting. In this embodiment, the orthographic projection of the trigger 330 on the circuit board 340 may be disposed adjacent to the orthographic projection of the mating member 320 on the circuit board 340, so that the trigger 330 detects the magnetic field of the connecting member 123 and the mating member 320. In some embodiments, the engaging element 320 may also be an electromagnet, and the triggering element 330 may trigger the electrical signal to supply power to the engaging element 320 when the connecting element 123 approaches the engaging element 320, so that the engaging element 320 may generate a magnetic force to magnetically connect with the connecting element 123.

In some embodiments, the trigger 330 may also be a distance sensor, which may be used to detect the distance between the leg body 121 and the housing 310, and then trigger an electrical signal to implement the function of the plug-in module 300. Alternatively, the triggering member 330 may also be an optical sensor, which can be used to detect the light quantity between the leg body 121 and the housing 310, and further trigger an electrical signal to implement the function of the plug-in module 300. In addition, in some embodiments, the trigger 330 may also be a metal contact, and accordingly, a corresponding metal contact may also be disposed on the leg main body 121. After the landing leg main body 121 and the plug-in module 330 are magnetically connected, the trigger 330 may contact with a metal contact on the landing leg main body 121 to form a short circuit or a circuit loop, thereby triggering an electrical signal to implement the function of the plug-in module 300. Or, the triggering member 330 may also be a pressure button, which may be abutted against the supporting leg main body 121 to generate an acting force after the supporting leg main body 121 and the plug-in module 330 are magnetically connected, so as to trigger the electrical signal to realize the function of the plug-in module 300.

Because the plug-in module 300 is provided with the geomagnetic sensor 350, in order to avoid the interference of the magnetic field of the connecting piece 123 and the fitting piece 320 on the geomagnetic sensor 350, the orthographic projection of the geomagnetic sensor 350 on the circuit board 340 can be further far away from the orthographic projection of the fitting piece 320 on the circuit board 340, so as to reduce the influence of the connecting piece 123 and the fitting piece 320 on the geomagnetic sensor 350. Meanwhile, the head-mounted device 10 may further include a magnetic shielding member 400 for shielding the magnetic field of the connecting member 123 and the mating member 320, so as to reduce the probability that the connecting member 123 and the mating member 320 interfere with the magnetic sensor (geomagnetic sensor 350) in the plug-in module 300. As shown in fig. 18, the magnetic shield 400 may be provided with a first magnetic shield 410 and a second magnetic shield 420. The first magnetic shielding member 410 is disposed on the leg 120, and the second magnetic shielding member 420 is disposed on the housing 310. The first magnetism isolating member 410 may be disposed in the first installation groove 1204, and the first magnetism isolating member 410 may be located between an inner wall of the first installation groove 1204 and the connecting member 123. Accordingly, the second magnetic shielding member 420 may also be disposed in the second mounting groove 311, and the second magnetic shielding member 420 may be located between the inner wall of the second mounting groove 311 and the mating member 320. Thus, the first magnetic shielding member 410 and the second magnetic shielding member 420 can shield the magnetic force of the connecting member 123 and the mating member 320, and at the same time, the magnetic force of the connecting member 123 and the mating member 320 is not affected.

In addition, in order to facilitate the detection of the trigger 330, the first magnetism isolating member 410 may further have a notch 411, so that the magnetic line of force of the connecting member 123 corresponding to the trigger 330 can extend to the trigger 330 through the notch 411, thereby directionally leaking the magnetic field of the connecting member 123 to the trigger 330, facilitating the detection of the trigger 330, and avoiding the problem that the function of the plug-in module 300 is disabled because the magnetic field of the connecting member 123 is small and cannot be detected by the trigger 330. Through the above manner, when the supporting leg main body 121 and the plug-in module 300 are magnetically connected through the connecting piece 123 and the mating piece 320, the influence of the connecting piece 123 and the mating piece 320 on the geomagnetic sensor 350 can be reduced by using the first magnetic isolating piece 410 and the second magnetic isolating piece 420, and the reliability of the positioning function of the plug-in module 300 is improved.

The head-mounted device 10 provided by the embodiment of the application sets up the fitting 320 on the external module 300 by setting up the connecting member 123 on the supporting leg 120, and sets up at least one of the connecting member 123 and the fitting 320 to have magnetic force, and sets up the connecting member 123 and the fitting 320 to be capable of magnetically attracting and connecting, so that the supporting leg 120 and the external module 300 can be detachably connected through the connecting member 123 and the fitting 320. Meanwhile, the magnetic shielding element 400 can shield the magnetic field of the connecting element 123 and/or the mating element 320, so that the probability that the connecting element 123 and/or the mating element 320 interfere with the magnetic induction element in the plug-in module 300 is reduced.
