When the temple is folded, the FPC component is not exposed, thereby improving product reliability.

Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted devices, and in particular to a foldable temple assembly and a head-mounted device. Background Art

[0002] In recent years, smart devices such as AR / VR / MR have been widely favored by consumers, and various head-mounted and glasses-type products have continued to emerge. Taking AR glasses as an example, AR glasses can bring users a rich visual experience and are worn on the user's head in the form of glasses, making them easy for users to use. The existing AR glasses on the market cannot be well adapted to various head shapes and ensure a certain clamping force, so the user's wearing experience is not very comfortable.

[0003] In addition, due to the small internal space of AR glasses, all the available space can be said to be arranged with related hardware, and FPC and other lines are spread throughout the entire product. When AR glasses are folded, FPC and other lines are often exposed to the outside. FPC and other lines are susceptible to wear, reducing the reliability and aesthetics of the product.

[0004] Furthermore, some AR glasses are equipped with a hinge mechanism to improve portability and storage. The hinge mechanism is only used to achieve the folding function, has a relatively simple function, and cannot provide other effects to improve the user experience.

[0015] The present invention also provides a head-mounted device, comprising the foldable temple assembly and FPC assembly as described above, wherein the FPC assembly is inserted into the first cavity, the gap between the elastic portion and the temple connecting portion, and the second cavity.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0045] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] The foldable temple assembly in this embodiment can be applied to head-mounted devices such as AR / VR / MR. The foldable temples can improve the wearing comfort of the head-mounted devices, and also facilitate the carrying and storage of the head-mounted devices when not in use.

[0047] Reference Figures 1 to 3 The foldable temple assembly in this embodiment mainly includes a frame 100, temples 200, a shaft portion and other parts. Figure 1 The figure shows a schematic diagram of the structure when the temple 200 is unfolded, at which time the head mounted device can be worn on the user's head. Figure 2 The figure shows a schematic diagram of the structure when the temple 200 is folded. At this time, the head-mounted device is not in use and is easy to carry and store. Figure 3 An exploded view of the foldable temple assembly.

[0048] The frame 100 and the temple 200 both have cavities inside, so as to facilitate the routing of the FPC components and other circuits in the head-mounted device and the installation of other functional modules. The internal cavity of the frame 100 is marked as a first cavity 110, and the internal cavity of the temple 200 is marked as a second cavity 210.

[0049] One end of the frame 100 is provided with a frame opening 120, which is communicated with the first cavity 110. One end of the temple 200 is provided with a temple opening 220, which is communicated with the second cavity 210. The frame opening 120 and the temple opening 220 are arranged opposite to each other.

[0050] The rotating shaft portion 300 includes a frame connection portion 310, a temple connection portion 320, and an elastic portion 330. The frame connection portion 310 extends through the frame opening portion 120 into the first cavity 110 and is rotationally connected to the inner wall of the frame 100. The temple connection portion 320 extends through the temple opening portion 220 into the second cavity 210 and is fixedly connected to the inner wall of the temple 200. The rotational connection between the frame connection portion 310 and the frame 100 realizes the rotational connection between the frame 100 and the temple 200.

[0051] When the temple 200 is bent toward the outside of the frame 100, the elastic part 330 abuts against the peripheral wall of the frame opening 120 to limit the reverse bending angle of the temple 200. The elastic part 330 is compressed and deformed by force so that the temple 200 has a tendency to move toward the inside of the frame 100, thereby enabling the temple 200 to maintain a certain clamping force when it is bent in the reverse direction. In addition, the amount of compression of the elastic part 330 is automatically adapted to the user's head circumference, thereby improving wearing comfort.

[0052] In some embodiments of the present application, refer to Figure 4 The elastic portion 330 includes an arc-shaped transition section 331 and an elastic deformation arm 332. One end of the arc-shaped transition section 331 is connected to the temple connecting portion 320, and the other end of the arc-shaped transition section 331 is connected to the elastic deformation arm 332. The temple connecting portion 320 and the elastic deformation arm 332 are located on the same side of the arc-shaped transition section 331, and there is a certain distance between the two, which provides movement space for the deformation of the elastic deformation arm 332.

[0053] When the elastic portion 330 is compressed and deformed by force, the elastic deformation arm 332 moves toward the direction close to the temple connecting portion 320, and the distance between the two is reduced. The elastic deformation arm 332 will give the temple 200 a force tending to move toward the inside of the frame 100, so that the temple 200 maintains a certain clamping force when bending in the reverse direction.

[0054] In some embodiments of the present application, continue to refer to Figure 4 The temple connecting portion 320 is a plate-shaped structure with a first screw hole 321; Figure 8 A first screw column 240 is correspondingly provided on the inner wall of the temple 200 , and screws are simultaneously passed through the first screw hole 321 and the first screw column 240 to fix the temple connecting portion 320 to the inner wall of the temple 200 .

[0055] There are three first screw holes 321 arranged in a triangle shape. The first screw columns 240 are arranged corresponding to the first screw holes 321 . The triangle shape structure helps to improve the connection reliability.

[0056] In this embodiment, the temple connection part 320, the arc-shaped transition section 331 and the elastic deformation arm 332 are integrally formed, and the material is preferably spring steel, which is easy to process, and the arc-shaped transition section 331 and the elastic deformation arm 332 are elastic and recoverable, meeting the structural requirements. The temple connection part 320 is mainly used for fixed connection with the temple 200, and the temple connection part 320 needs to meet a certain structural strength. In combination with the different functional requirements of the two parts of the structure, the thickness of the arc-shaped transition section 331 and the elastic deformation arm 332 is designed to be less than the thickness of the temple connection part 320.

[0057] In some embodiments of the present application, refer to Figure 5 A reset member 340 is provided between the elastic deformation arm 332 and the temple connection portion 320. The reset member 340 may be a spring. The reset member 340 is preferably provided near the free end of the elastic deformation arm 332. When the elastic deformation arm 332 is compressed and deformed toward the temple connection portion 320, the reset member 340 is compressed and provides a rebound force to the elastic deformation arm 332, which can improve and ensure the reset ability of the elastic deformation arm 332. At the same time, the reset member 340 can also provide a clamping force when the temple 200 is bent in the reverse direction.

[0058] In some embodiments of the present application, refer to Figure 4 The elastic deformation arm 332 is provided with a deformation limiting portion 333, which extends toward the temple connection portion 320. When the temple 200 is bent toward the outside of the frame 100, the elastic deformation arm 332 will be deformed toward the temple connection portion 320 by force. When the deformation limiting portion 333 abuts against the temple connection portion 320, the temple 200 will not be able to continue to bend outward, and the temple 200 reaches the maximum angle of reverse bending. By setting the size structure of the deformation limiting portion 333, the temple 200 can have different maximum reverse bending angles.

[0059] In some embodiments of the present application, refer to Figure 4 , the frame connection part 310 includes a fixed connection arm 311 and a rotating connection disk 312, and the fixed connection arm 311 and the rotating connection disk 312 are respectively provided with two and are respectively arranged at the upper and lower sides of the temple connection part 320. The fixed connection arm 311 is a long strip structure, one end of which is fixedly connected to the temple connection part 320, and the other end is fixedly connected to the rotating connection disk 312. The rotating connection disk 312 is provided with a first shaft hole 314, and the side wall of the frame 200 is correspondingly provided with a second shaft hole 160. The first shaft hole 314 and the second shaft hole 160 are simultaneously penetrated with shaft pins to realize the rotating connection between the rotating connection disk 312 and the frame 100. In other embodiments, the first shaft hole 314 can also be a screw hole, and a screw is simultaneously penetrated in the screw hole and the second shaft hole 160, and there is a certain gap between the screw and the second shaft hole 160, which can also realize the rotating connection between the rotating connection disk 312 and the frame 100.

[0060] In this embodiment, the frame connection part 310 can be made of high-strength steel to ensure connection reliability. The frame connection part 310, the temple connection part 320, and the elastic part 330 are made of different materials and cannot be processed in an integrated manner. Instead, welding can be used to achieve fixed installation between the frame connection part 310 and the temple connection part 320.

[0061] In some embodiments of the present application, refer to Figure 3 and Figure 4 A damping member 350 is provided between the rotating connection disk 312 and the inner wall of the frame 100, and the damping member 350 may be a silicone gasket. When the temple 200 rotates relative to the frame 100, the contact friction between the silicone gasket and the inner wall of the frame 100 and the rotating connection disk 312 can provide a certain damping effect when the temple 200 rotates, thereby improving the folding feel of the temple 200 when rotating.

[0062] In this embodiment, a groove 313 is provided on the rotating connecting disk 312, and the damping member 350 is fixed into the groove 313 by gluing, which is easy to install and has a reliable structure.

[0063] In some embodiments of the present application, refer to Fig. 9 A limiting portion 150 is provided at the opening portion 120 of the mirror frame. The limiting portion 150 is a protruding structure facing the inner side of the first cavity 110 . The limiting portion 150 has a first limiting surface 151 and a second limiting surface 152 . A stopper 360 is provided on the outer side of the arc-shaped transition section 331 .

[0064] Reference Fig.10 When the temple 200 is folded toward the inside of the frame 100, the stopper 360 moves toward the direction close to the limiting portion 150. When the stopper 360 abuts against the first limiting surface 151, the temple 200 folds inwards to a maximum angle, and the temple 200 cannot continue to fold inwards. By setting the stopper 360 at different positions on the arc-shaped transition section 331, the temple 200 can have different maximum folding angles.

[0065] Reference Fig.11 When the temple 200 is bent in the opposite direction toward the outside of the frame 100, the elastic deformable arm 332 moves toward the direction close to the limiting portion 150. When the elastic deformable arm 332 abuts against the second limiting surface 152, the temple 200 continues to be bent outward. The elastic deformable arm 332 will be compressed and deformed by the force. At this time, the elastic deformable arm 332 will give the temple 200 a rebound force, so that the temple 200 has a tendency to move toward the inside of the frame 100, so that the temple 200 maintains a certain clamping force.

[0066] In some embodiments of the present application, refer to Fig. 9The end of the frame 100 close to the temple 200 has a first arc surface 130, and the end of the temple 200 close to the frame 100 has a second arc surface 230. The first arc surface 130 is adapted to the second arc surface 230, and there is a certain gap between the two, and the gap is small, so that the temple 200 can be folded along the first arc surface 130 better, and the internal wiring harness is avoided from being exposed, thereby improving the aesthetics.

[0067] from Figure 1 and Figure 2 It can be seen that after the frame 100, the temples 200 and the hinge portion 300 are assembled, only the arc-shaped transition section 331 in the hinge portion 300 is partially exposed, which can well shield the internal wiring harness and other components.

[0068] The head-mounted device in this embodiment includes the foldable temple assembly and the FPC assembly 400 disclosed in the above embodiment, Figure 6 and Figure 8 The FPC assembly 400 is disposed in the first cavity 110 , the gap between the elastic portion 330 and the temple connecting portion 320 , and the second cavity 210 .

[0069] In some embodiments of the present application, refer to Figure 8 The FPC assembly 400 is a three-section structure, which includes an FPC section 1 410, an FPC section 2 420, and an FPC section 3 430. The FPC section 1 410 is disposed in the first cavity 110, and the FPC section 3 430 is disposed in the second cavity. Figure 7 , which includes a U-shaped section 421 and an extension section 422, and then combined Figure 6 The U-shaped section 421 is hung on the arc-shaped transition section 331, one end of the U-shaped section 421 extends into the first cavity 110 through the frame opening 120, and is connected to the FPC section 1 410 through a connector; the extension section 422 extends toward the second cavity 210 along the gap between the elastic portion 330 and the temple connecting portion 320, one end of the extension section 422 extends into the second cavity 210 through the temple opening 220, and is connected to the FPC section 3 430 through a connector.

[0070] As can be seen from Figure 4, the temple connection portion 320, the arc-shaped transition section 331 and the elastic deformation arm 332 form a U-shaped accommodating cavity 370, the opening of the U-shaped accommodating cavity 370 faces the temple 200 side, and there is a certain distance between the rotating connection disk 312 and the arc-shaped transition section 331. When installing the FPC assembly 400, first lay the FPC second section 420 flat and extend it into the space between the upper rotating connection disk 312 and the arc-shaped transition section 331, and then flip the FPC second section 420 to be vertical, so that the opening of the U-shaped section 421 faces downward, and then the U-shaped section 421 is hung on the arc-shaped transition section 331. The U-shaped accommodating cavity 370 plays a role in storing and shielding the FPC assembly 400, so that when the temple 200 rotates, the FPC assembly 400 will not be exposed.

[0071] In some embodiments of the present application, refer to Figure 7 and Figure 8 The ends of the U-shaped section 421 and the extension section 422 are respectively provided with reinforcing plates 440, a second screw hole 441 is provided on the reinforcing plate 440 close to the side of the frame 100, and a third screw hole 442 is provided on the reinforcing plate 440 close to the side of the temple 200; correspondingly, a second screw column 140 is provided on the inner wall of the frame 100, and a third screw column 250 is provided on the inner wall of the temple 200; screws are simultaneously inserted between the second screw hole 441 and the second screw column 140, and between the third screw hole 442 and the third screw column 250, so as to realize the fixed installation of both ends of the second section 420 of the FPC and improve reliability.

[0072] In this embodiment, the installation structure of the first FPC segment 410 and the U-shaped segment 441 in the first cavity 110 of the frame and the installation structure of the third FPC segment 430 and the extension segment 422 in the second cavity 210 of the temple are the same. This embodiment is described with reference to the third FPC segment 430. Fig.13 A supporting rib 450 and a sponge 460 are provided on the inner wall of the temple 200. The supporting rib 450 is close to the inner wall of the temple 200, the sponge 460 is close to the supporting rib 450, the end of the third FPC section 430 is close to the sponge 460, and a connector 470 is also provided at the end of the third FPC section 430. The supporting rib 450, the sponge 460 and the connector 470 are located between the two third screw columns 250. The reinforcing plate 440 at the end of the extension section 422 is fixed on the third screw column 250 by screws, so that the end of the extension section 422, the end of the third FPC section 430, and the connector 470 can be more reliably contacted and connected.

[0073] In this embodiment, when the temple 200 rotates, the three-section FPC assembly 400 Fig.12, only the area A in the second FPC section 420 undergoes a certain bending change with the temple 200, and the bending radius is relatively large. The U-shaped accommodation cavity 370 provides the second FPC section 420 with a larger movement space without extrusion contact, thereby preventing the second FPC section 420 from being damaged during the bending process, thereby improving the reliability of the FPC assembly 400. When the temple 200 is folded inward, the second FPC section 420 extends from P1 to P2; when the temple 200 is unfolded, the second FPC section 420 extends from P1 to P3.

[0074] In this embodiment, refer to Figure 6 The deformation limiting portion 333 is a plate-shaped structure. The plate-shaped deformation limiting portion 333 blocks the upper and lower sides of the U-shaped accommodating cavity 370, thereby limiting the FPC component 400 (specifically the extension section 422) in the U-shaped accommodating cavity 370, thereby preventing the extension section 422 from escaping from the U-shaped accommodating cavity 370.

[0075] For head mounted devices, refer to Fig.14 When the wiring harness 500 composed of other circuits is routed, its routing path is the same as that of the FPC assembly 400. The wiring harness 500 is also passed through the first cavity 110, the U-shaped accommodating cavity 370 of the shaft portion 300, and the second cavity 210. When the temple 200 is folded, the wiring harness 500 can be prevented from being exposed.
