Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted devices, and in particular to a temple assembly capable of reverse bending and providing clamping force, 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.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0050] Reference Figure 1 The temple assembly in this embodiment can be applied to head-mounted devices 10 such as AR / VR / MR. The foldable temples can improve the wearing comfort of the head-mounted device, and also facilitate the carrying and storage of the head-mounted device when not in use.

[0051] Refer to 2 to Figure 5 The temple assembly includes a first rotating arm 100, a second rotating arm 200 and a rotating shaft assembly 300.

[0052] The first rotating arm 100 is fixedly connected to the frame 11 via a mechanical structure or the first rotating arm 100 and the frame 11 are integrally formed, and the second rotating arm 200 and the temple 12 are fixedly connected to the frame 11 via a mechanical structure or the second rotating arm 200 and the temple 12 are integrally formed.

[0053] The rotating shaft assembly 300 is connected to the first rotating arm 100 . The rotating shaft assembly 300 can move along the length direction of the first rotating arm 100 under the action of external force. The rotating shaft assembly 300 is also rotationally connected to the second rotating arm 200 .

[0054] The first rotating arm 100 and the second rotating arm 200 are rotatably connected via the rotating shaft assembly 300 to realize the rotation of the temple 12 relative to the frame 11, that is, to realize the folding function of the temple assembly.

[0055] When the second rotating arm 200 rotates toward the inside of the first rotating arm 100, that is, when the temple 12 is folded toward the inside of the frame 11, the position of the rotating shaft assembly 300 relative to the first rotating arm 100 is fixed, and relative rotation occurs between the second rotating arm 200 and the rotating shaft assembly 300, thereby realizing the inward rotation of the second rotating arm 200, that is, realizing the inward folding of the temple 12.

[0056] When the second rotating arm 200 rotates toward the outside of the first rotating arm 100, that is, when the temple 12 bends toward the outside of the frame 11, the shaft assembly 300 moves along the length direction of the first rotating arm 100, and at the same time, relative rotation occurs between the second rotating arm 200 and the shaft assembly 300, thereby realizing the outward rotation of the second rotating arm 200, that is, realizing the reverse bending of the temple 12.

[0057] If the user has a large head circumference, the temple assembly can be worn by bending the temple 12 outward, so that the temple assembly can be adapted to users with different head circumferences, thereby improving the wearing comfort of the user.

[0058] At the same time, the shaft assembly 300 will apply a force to move the second rotating arm 200 toward the inside of the first rotating arm 100, so that the second rotating arm 200 can maintain a certain clamping force when bent in the reverse direction, thereby preventing the entire temple assembly from slipping off when bent in the reverse direction and making it comfortable and reliable to wear.

[0059] The shaft assembly 300 in this embodiment plays the role of rotational connection and providing clamping force, so that the temple assembly has the functions of forward folding and reverse bending, and the temple 12 has a certain clamping force when bending in the reverse direction.

[0060] The temple assembly is easy to store and carry, and can be adapted to users with different head circumferences, thereby improving the wearing comfort and reliability of the users.

[0061] In some embodiments of the present application, refer to Figures 6 to 8 The rotating shaft assembly 300 includes a rotating connecting portion 310 and a resetting portion 320 , and the rotating connecting portion 310 and the resetting portion 320 are connected.

[0062] The rotation connection portion 310 is used to be rotationally connected to the second rotating arm 200 to achieve a rotational connection between the rotating shaft assembly 300 and the second rotating arm 200 .

[0063] The resetting portion 320 is used to be connected to the first rotating arm 100 to achieve the connection between the rotating shaft assembly 300 and the first rotating arm 00 .

[0064] Reference Fig.13 and Fig.14 When the second rotating arm 200 rotates toward the inside of the first rotating arm 100, the positions of the rotating connecting portion 310 and the resetting portion 320 relative to the first rotating arm 100 are fixed, and a relative rotation occurs between the second rotating arm 200 and the rotating connecting portion 310, thereby realizing the inward folding of the second rotating arm 200.

[0065] Reference Fig.15 The second rotating arm 200 rotates toward the outside of the first rotating arm 100 until the outer end wall of the first rotating arm 100 abuts against the outer end wall of the second rotating arm 200 at point P, and the second rotating arm 200 continues to rotate outward. The second rotating arm 200 will drive the rotating connection part 310 to move in the direction away from the first rotating arm 100 with point P as the fulcrum, and the reset part 320 will move along with the rotating connection part 310 along the length direction of the first rotating arm 100. The reset part 320 is deformed by the force, and the reset part 320 will apply a force to make the second rotating arm 200 move toward the inside of the first rotating arm 100, so that the second rotating arm 200 has a certain clamping force when it is bent in the opposite direction.

[0066] The rotating connection part 310 is used to realize the rotating connection function of the shaft assembly 300, and the reset part 320 is used to provide a clamping force when the second rotating arm 200 is bent in the reverse direction. The structure is simple and compact, and it is convenient to connect with the first rotating arm 100 and the second rotating arm 200.

[0067] In some embodiments of the present application, continue to refer to Figures 6 to 8 The reset portion 320 includes a guide rod 321 , a reset spring 322 and a limiting portion 323 .

[0068] The guide rod 321 is a long rod-shaped structure, one end of which is fixedly connected to the rotating connection part 310 , and the other end of which is sleeved with a return spring 322 . The guide rod 321 guides the contraction and rebound of the return spring 322 .

[0069] The limiting portion 323 is disposed on the guide rod 321 and abuts against one end of the return spring 322 , limiting the outer end of the return spring 322 to prevent the return spring 322 from falling off the guide rod 321 .

[0070] The limiting portion 323 may be a nut, which can be directly screwed and locked with the guide rod 321 for easy assembly and disassembly.

[0071] The first rotating arm 100 is provided with a through hole 150 along its length direction, and a stopper 151 is formed in the through hole 150. Specifically, the through hole 150 has two through-hole sections with different apertures, and a transition step is formed between the two through hole sections with different apertures, and the transition step is the stopper 151.

[0072] The guide rod 321 is inserted into the through hole 150 and can move along the length direction of the through hole 150. The return spring 322 is located in the through hole 150. The other end of the return spring 322 abuts against the stopper 151. The limiting portion 323 and the stopper 151 jointly limit the displacement of the return spring 322.

[0073] Reference Fig.15 When the second rotating arm 200 rotates toward the outside of the first rotating arm 100, the second rotating arm 200 drives the rotating connection part 310 to move away from the first rotating arm 100, and the rotating connection part 310 will drive the guide rod 321 to move toward the direction close to the second rotating arm 200, and the limiting part 323 will move together toward the direction close to the stop part 151. At this time, the return spring 322 will be compressed, and the return spring 322 will apply a force to restore the guide rod 321. The guide rod 321 transmits the restoring force to the second rotating arm 200 through the rotating connection part 310, so that the second rotating arm 200 can have a certain clamping force when it is bent in the reverse direction.

[0074] In some embodiments of the present application, there are two reset parts 320, and the two reset parts 320 are symmetrically arranged, so that the second rotating arm 200 can be evenly stressed when bending in the reverse direction, and the clamping force provided is more reliable.

[0075] In some embodiments of the present application, refer to Figure 4 and Figure 5 The rotating connection part 310 is a cylindrical structure. The upper and lower sides of the second rotating arm 200 are respectively provided with connecting plates 250. The connecting plates 250 are located on the outer side of the rotating connection part 310. The rotating connection part 310 and the connecting plates 250 are rotatably connected through a pin shaft 330.

[0076] The cylindrical structure of the rotating connection portion 310 can avoid interference between the first rotating arm 100 and the second rotating arm 200 when they rotate relative to each other, which is conducive to realizing a compact design of the structure.

[0077] The connecting plate 250 also shields the rotating connecting portion 310, making the temple assembly more beautiful as a whole.

[0078] In some embodiments of the present application, refer to Figure 8 The rotating connection part 310 includes two connection columns 311 spaced apart from each other, a shielding part 312 is provided between the two connection columns 311 , and a first wiring gap 313 is formed between the two connection columns 311 .

[0079] Reference Figure 4 , Figures 9 to 12 A first cavity 110 is formed in the first rotating arm 100 , and a first wiring opening 120 communicating with the first cavity 110 is provided at an end of the first rotating arm 100 close to the second rotating arm 200 .

[0080] A second cavity 210 is formed in the second rotating arm 200 , and a second wiring opening 220 communicating with the second cavity 210 is provided at an end of the second rotating arm 200 close to the first rotating arm 100 .

[0081] The FPC 400 is inserted into the temple assembly, and the FPC 400 is sequentially inserted into the first cavity 110, the first wiring opening 120, the first wiring gap 313, the second wiring opening 220 and the second cavity 210 to realize the wiring of the FPC 400 in the temple assembly.

[0082] When the second rotating arm 200 rotates toward the inner side of the first rotating arm 100, the shielding portion 312 is used to shield the FPC 400 to prevent the FPC 400 from being exposed and abraded when the temple assembly is folded.

[0083] In some embodiments of the present application, the shielding portion 312 is an arc-shaped structure, and the arc center angle of the arc-shaped structure where the shielding portion 312 is located is not less than the maximum angle that the second rotating arm 200 can rotate toward the inside of the first rotating arm 100 to ensure that the shielding portion can completely shield the FPC 400.

[0084] Reference Fig.14 The arc center angle of the arc structure where the shielding portion 312 is located is represented by α. In this embodiment, α is designed to be 90°, and the maximum angle that the second rotating arm 200 can rotate toward the inner side of the first rotating arm 100 is also 90°.

[0085] In some embodiments of the present application, refer to Fig.12 A limiting rib 230 is provided in the second cavity 210, and a second wiring gap 240 is formed between the limiting rib 230 and the inner wall of the second rotating arm 200. The FPC 400 passes through the second wiring gap 240, which can prevent the FPC 400 from shaking in the second cavity 210 and improve the reliability of the FPC 400.

[0086] In some embodiments of the present application, refer to Figure 4 and Figure 5 An arc-shaped paving portion 140 is formed at the end of the first rotating arm 100 close to the second rotating arm 200, the first wiring opening 120 is arranged on the arc-shaped paving portion 140, and the rotating connecting portion 310 is located in the arc-shaped paving portion 140, so that the rotating connecting portion 310 can be better and compactly assembled with the first rotating arm 100.

[0087] The inner side of the first rotating arm 100 is provided with an extension portion 130, referring to Figure 12 to Figure 14 The extension portion 130 can shield the rotating connection portion 310, and the FPC 400 routed through the first routing gap 313 will not be exposed. The entire rotating connection portion 310 is not exposed, and the overall structure of the temple assembly is more compact and beautiful.

[0088] Reference Figure 2 and Fig.12 When the first rotating arm 100 and the second rotating arm 200 are not rotating relative to each other, the end of the extension portion 130 is as close to the side wall of the second rotating arm 200 as possible to avoid a large gap between the two to affect the appearance.

[0089] Reference Fig.13 When the second rotating arm 200 rotates toward the inside of the first rotating arm 100, the extension portion 130 extends into the second wiring opening 220, and the extension portion 130 shields the internal rotating connection portion 310 and the first wiring gap 313 to prevent the rotating connection portion 310 and the FPC 400 from being exposed.

[0090] Reference Fig.14 When the second rotating arm 200 rotates to the inner side of the first rotating arm 100 to the maximum angle position, the end of the extension portion 130 extends into the second wiring opening 220 and there is a certain gap between the end of the extension portion 130 and the inner wall of the second rotating arm 200. The gap is used to avoid interfering with the wiring of the FPC 400, and the FPC 400 passes through the gap.

[0091] In this embodiment, the end of the extension portion 130 is designed to be an arc structure to prevent the FPC 400 from being damaged by a sharp corner structure.

[0092] Reference Fig.14 When the second rotating arm 200 rotates toward the inside of the first rotating arm 100, when the inner end wall of the second rotating arm 200 abuts against the inner wall of the first rotating arm 100, the second rotating arm 200 rotates inwardly to the maximum angle position to achieve the limit when folding inwardly.
