Abstract
Description
Technical Field
[0001] This utility model relates to a hinge in a wearable device, particularly AR glasses. Background Technology
[0002] AR glasses include a frame and temples. The temples are rotatably connected to the frame via hinges. Furthermore, a wire needs to pass between the temples and the frame through the hinge. Obviously, it's best not to expose the wire when it passes through the hinge. This often depends on the thickness of the auxiliary structures connected to the connecting frames on both sides of the hinge. If the thickness is sufficient, the wire opening can be covered by the auxiliary structures throughout the full opening range of the hinge. If the thickness is insufficient, the wire opening will not be covered within a certain angle range. Utility Model Content
[0003] The purpose of this invention is to provide a hinge with a wire-passing function for wearable devices, which can better conceal the wire opening without relying entirely on the thickness of the attached structure. To this end, this invention adopts the following technical solution:
[0004] A hinge with a wire-passing function for wearable devices includes a first connecting frame and a second connecting frame, which are rotatably connected about an axis, allowing the first and second connecting frames to rotate relative to each other about the axis. The hinge further includes a wire-passing cylinder, which is movably connected to the first and second connecting frames and can rotate about the axis relative to them. The wire-passing cylinder includes two wire-passing grooves arranged in the direction of rotation, and the maximum rotation angle of the wire-passing cylinder is less than the maximum relative rotation angle between the first and second connecting frames and the central angle between the two wire-passing grooves.
[0005] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:
[0006] The hinge is provided with a connection structure, and can drive the wire guide to rotate in a first direction by rotating the first connecting frame or the second connecting frame. The hinge is provided with a reset elastic component for the wire guide, and drives the wire guide to rotate in a second direction. The first direction is one of clockwise and counterclockwise directions, and the second direction is the other of clockwise and counterclockwise directions.
[0007] The connection structure is a clutch connection structure. The maximum relative rotation angle range between the first connecting frame and the second connecting frame includes a first angle range and a second angle range. The second angle range corresponds to the maximum rotation angle of the wire guide drum. In the first angle range, in the first direction, the rotation of the first connecting frame or the second connecting frame does not drive the wire guide drum to rotate. In the second angle range, in the first direction, the rotation of the first connecting frame or the second connecting frame drives the wire guide drum to rotate while the reset elastic component stores energy. In the second angle range, in the second direction, the reset elastic component releases energy and drives the wire guide drum to rotate. In the first angle range, in the second direction, the wire guide drum is restricted and cannot rotate with the first connecting frame or the second connecting frame.
[0008] A first indexing groove and a first key rotation angle limiting fit are provided between the wire guide and the first connecting frame. A second indexing groove and a second key rotation angle limiting fit are provided between the wire guide and the second connecting frame. The maximum rotation angle of the first key in the first indexing groove and the maximum rotation angle of the second key in the second indexing groove correspond to the maximum relative rotation angle of the first connecting frame and the second connecting frame. The rotation angle of the first key in the first indexing groove and the rotation angle of the second key in the second indexing groove partially overlap, and the overlapping angle range corresponds to the maximum rotation angle of the wire guide.
[0009] One end of the wire guide tube is provided with a first indexing groove, and the first connecting frame is provided with a first key. The other end of the wire guide tube is provided with a second indexing groove, and the second connecting frame is provided with a second key.
[0010] "In the second angular range, the rotational limit position of the first connecting frame or the second connecting frame in the first direction", "In the second angular range, the rotational limit position of the wire guide in the second direction" and "In the first angular range, the rotational limit position of the first connecting frame or the second connecting frame in the second direction" are achieved by "the rotational angle of the first key in the first indexing groove partially overlaps with the rotational angle of the second key in the second indexing groove", which results in the limiting fit between the groove wall of the indexing groove and the key.
[0011] The reset elastic component is disposed between the second mounting bracket and the wire guide.
[0012] The axis is the center line of the connecting shaft of the first connecting frame and the second connecting frame. The first connecting frame and the second connecting frame are respectively provided with a coaxial directional positioning structure. The two ends of the wire guide tube are respectively positioned on the directional positioning structure on the first connecting frame and the second connecting frame. The connecting shaft passes through the wire guide tube.
[0013] The hinge is also provided with a rotation resistance mechanism, which includes a compression spring disposed in the wire guide and sleeved on the connecting shaft, an adjusting screw, and a first friction structure and a second friction structure pressed by the compression spring. The first friction structure is connected to one of the first connecting frame or the second connecting frame, and the second friction structure is pressed onto the first friction structure by the compression spring. The adjusting screw is threaded to the connecting shaft on the other of the first connecting frame or the second connecting frame to adjust the compression of the compression spring.
[0014] By adopting the technical solution of this utility model, the maximum rotation angle of the sleeve with the wire groove can be adjusted according to the actual application by rotating and not rotating the sleeve at different opening angles of the hinge. This allows for targeted shielding of the wire groove without relying entirely on the thickness of the auxiliary structure. Attached Figure Description

[0020] Referring to the accompanying drawings, this embodiment uses a hinge applied to AR glasses as an example. The hinge with a wire-passing function includes a first connecting frame 1 and a second connecting frame 2, which are respectively connected to the frame and temple of the AR glasses. The first connecting frame 1 and the second connecting frame 2 are rotatably connected around an axis, allowing the first connecting frame 1 and the second connecting frame 2 to rotate relative to each other around the axis, which is the center line of the connecting shaft 3.
[0021] The hinge is also provided with a wire guide tube 4, which is movably connected to the first connecting frame 1 and the second connecting frame 2 and can rotate around the axis. Relative to the first connecting frame 1 and the second connecting frame 2, the wire guide tube includes two wire guide grooves 41 and 42 arranged in the rotation direction, which are used for wire entry and exit from the frame and the temple side, respectively. The maximum rotation angle of the wire guide tube 4 is less than the maximum relative rotation angle α of the first connecting frame 1 and the second connecting frame 2 and the central angle β between the two wire guide grooves.
[0022] The hinge is provided with a connection structure, and can drive the wire guide 4 to rotate in a first direction by rotating the first connecting frame 1 or the second connecting frame 2. The hinge is provided with a reset elastic component 5 for the wire guide 4, which drives the wire guide 4 to rotate in a second direction. The first direction is one of clockwise and counterclockwise directions, and the second direction is the other of clockwise and counterclockwise directions. The reset elastic component 5 can be a torsion spring.
[0023] The connection structure can adopt a clutch connection structure. The maximum relative rotation angle range between the first connecting frame 1 and the second connecting frame 2 includes a first angle range and a second angle range. The second angle range corresponds to the maximum rotation angle of the wire guide 4. Within this range, the wire guide 4 rotates. The first angle range is the idle rotation angle of the first connecting frame 1 and the second connecting frame 2. The ratio between the first angle range and the second angle range can be determined according to the shape of different AR glasses. By adjusting the size of the second angle range, the wire guide groove can be specifically shielded without relying entirely on the thickness of the auxiliary structure. Figure 1 As shown, in this embodiment, it is assumed that the maximum relative rotation angle range of the first connecting frame 1 and the second connecting frame 2 is 90°, and the first angle range and the second angle range are both 45°. At 0°, the wire grooves 41 and 42 are respectively shielded by the auxiliary structures outside the first connecting frame 1 and the second connecting frame 2. Process A represents the working effect of this invention. As can be seen from the figure, since the maximum relative rotation angle range of the first connecting frame 1 and the second connecting frame 2 is the sum of the first angle range and the second angle range, and the rotation angle of the wire guide 4 is only within the second angle range, the wire groove 42 is just shielded after the first connecting frame 1 rotates 90°. In process B, assuming the wire guide 4 cannot rotate, the wire groove 42 is exposed between the first connecting frame 1 and the second connecting frame 2. In process C, assuming the relative rotation angle of the wire guide 4 is the same as that of the first connecting frame 1 and the second connecting frame 2, the wire groove 41 on the other side enters between the first connecting frame 1 and the second connecting frame 2 and is exposed.
[0024] Within a first angular range and in a first direction, the rotation of the first connecting frame 1 or the second connecting frame 2 does not cause the wire guide 4 to rotate. Within a second angular range and in the first direction, the rotation of the first connecting frame 1 or the second connecting frame 2 causes the wire guide 4 to rotate while the reset elastic component 5 stores energy. Within a second angular range and in a second direction, the reset elastic component 5 releases energy and causes the wire guide 4 to rotate. Within a first angular range and in the second direction, the wire guide 4 is restricted and cannot rotate with the first connecting frame 1 or the second connecting frame 2.
[0025] The clutch connection structure can adopt the following structure: one end of the wire guide spool 4 is provided with a first indexing groove 43, the first connecting frame 1 is provided with a first key 11, and the first indexing groove 43 and the first key 11 are matched with a rotation angle limit. The other end of the wire guide spool 4 is provided with a second indexing groove 44, the second connecting frame 2 is provided with a second key 21, and the second indexing groove 44 and the second key 21 are matched with a rotation angle limit. The maximum rotation angle of the first key 11 in the first indexing groove 43 and the maximum rotation angle of the second key 21 in the second indexing groove 44 correspond to the maximum relative rotation angle of the first connecting frame 1 and the second connecting frame 2. The rotation angle of the first key 11 in the first indexing groove 43 and the rotation angle of the second key 21 in the second indexing groove 44 partially overlap (that is, their central angles partially overlap in the axial projection). The overlapping angle range corresponds to the maximum rotation angle of the wire guide spool 4.
[0026] Preferably, the rotational limit positions of the first connecting frame 1 or the second connecting frame 2 in the first direction within the second angular range, the rotational limit positions of the wire guide 4 in the second direction within the second angular range, and the rotational limit positions of the first connecting frame 2 or the second connecting frame 3 in the second direction within the first angular range are achieved by the partial overlap of the rotation angle of the first key 11 in the first indexing groove 43 with the rotation angle of the second key 32 in the second indexing groove 44. This results in the limiting fit between the groove wall of the indexing groove and the key, thus simplifying the structure. Taking this embodiment as an example, at 0°, the first key 11 engages with the first end face 431 of the first indexing groove 43 to initially prevent the wire guide 4 from moving in the opposite direction. In the first direction within the first angle range, the first connecting frame 1 rotates 45° until the first key 11 knocks down the second end face 432 of the first indexing groove 43. In the first direction within the second angle range, the first connecting frame 1, through the engagement of the first key 11 with the second end face 432 of the first indexing groove 43, drives the wire guide 4 to rotate another 45° until the second end face 442 of the second indexing groove 44 knocks down the second key 21 and is limited, stopping the rotation. In the second direction within the second angle range, when the first connecting frame 1 rotates, the reset elastic component 5 drives the wire guide 4 to rotate in the second direction until the first end face 441 of the second indexing groove 44 knocks down the second key 21 and cannot continue rotating. The first connecting frame continues to rotate 45° in the first direction until the first key 11 knocks down the first end face 431 of the first indexing groove and is limited, stopping the rotation.
[0027] In this embodiment, the reset elastic component 5 is a torsion spring, which is disposed between the second mounting bracket 2 and the wire guide 4. The second mounting bracket 2 is provided with a slot 22 for one end of the torsion spring support leg, and the wire guide 4 is provided with a slot 45 for the other end of the torsion spring.
[0028] The first connecting frame 1 and the second connecting frame 2 are respectively provided with coaxial radial positioning structures 10 and 20. The two ends of the wire guide 4 are respectively positioned on the radial positioning structures 10 and 20 on the first connecting frame 1 and the second connecting frame 2. The connecting shaft 3 passes through the wire guide 4.
[0029] In this embodiment, a rotational resistance mechanism is also provided using the wire guide spool 4. The rotational resistance mechanism includes a compression spring 61 disposed in the wire guide spool and sleeved on the connecting shaft 3, an adjusting screw 62, and a first friction structure 63 and a second friction structure 64 pressed by the compression spring 61. The first friction structure 63 is connected to one of the first connecting frame 1 or the second connecting frame 3, and the second friction structure 64 is pressed by the compression spring 61 onto the first friction structure 63. The adjusting screw 62 is connected to the connecting shaft 3 on the other side of the first connecting frame 1 or the second connecting frame 2, and is used to adjust the compression of the compression spring 61, thereby adjusting the frictional resistance.
