[0039] Please refer to Figures 1 to 11 As shown, the present invention discloses a hinge structure that can be used for an earphone charging box or other box-type electronic products, and after the cover is opened or closed, the relative position of the cover and the box can be limited.

[0040] See also Figure 1 The shaft structure includes a first rotating body 1, a second rotating body 2 and a rotating shaft 3. The rotating shaft 3 is passed through the first rotating body 1 and the second rotating body 2. The first rotating body 1 is configured to connect the box body, and the second rotating body 2 is configured to connect the cover body. The second rotating body 2 can rotate around the rotating shaft 3 relative to the first rotating body 1 to realize the opening and closing between the cover body and the box body.

[0041] In this embodiment, the shape of the first rotating body 1 and the second rotating body 2 after assembly can be a part of a sphere or a sphere, which can be suitable for a charging box with an arc-shaped rotation position, while hinges or linear shafts are not suitable for such charging boxes.

[0042] See also Figure 2 The first rotating body 1 includes a first rotating arm 11 and a first rotating disk 12. The first rotating arm 11 is provided with a first connecting portion 1112, and the first connecting portion 1112 is connected to the box body. The first rotating arm 11 has a first inner cavity 110, and the first rotating disk 12 is provided in the first inner cavity 110. The first rotating disk 12 is provided with a first tooth portion 121 on a side facing the second rotating body 2. The second rotating body 2 is configured to connect to the cover body, and the second rotating body 2 is provided with a second tooth portion 221 on a side facing the first rotating disk 12. The second tooth portion 221 can mesh with the first tooth portion 121, and is used to define the first rotating body 1 and the second rotating body 2.

[0043] The driving mechanism 4 is at least partially disposed in the first inner cavity 110 of the first rotating arm 11. Figure 6 The driving mechanism 4 includes a driving member 41 and a first elastic member 42. The driving member 41 is connected to the first rotating disk 12. The two ends of the first elastic member 42 are respectively connected to the driving member 41 and the first rotating arm 11. When the cover needs to be opened, an external force is applied to the driving member 41, so that the driving member 41 moves toward the first inner cavity 110 along the radial direction of the first rotating arm 11 and compresses the first elastic member 42. The driving member 41 drives the first rotating disk 12 to move along the axial direction of the first rotating arm 11 and away from the second rotating body 2, so that the first tooth portion 121 is separated from the second tooth portion 221, so that the second rotating body 2 is unlocked from the first rotating body 1. At this time, the second rotating body 2 can rotate relative to the first rotating body 1 around the rotating shaft 3, so that the cover can be opened relative to the box body; after the cover is opened, the driving member 41 is reset by the rebound of the first elastic member 42, and the driving member 41 drives the first rotating disk 12 is close to the second rotating body 2, and the first tooth portion 121 is meshed with the second tooth portion 221, so that the second rotating body 2 is relatively locked with the first rotating body 1; when the cover needs to be closed, an external force is applied to the driving member 41 again, and the driving member 41 drives the first rotating disk 12 away from the second rotating body 2, so that the second rotating body 2 and the first rotating body 1 are unlocked again, so that the first tooth portion 121 is separated from the second tooth portion 221, so that the cover can be closed relative to the box body; after the cover is closed, the first elastic member 42 rebounds and drives the driving member 41 to reset, and the first tooth portion 121 is meshed with the second tooth portion 221, so that the first rotating body 1 and the second rotating body 2 are limited. Optionally, the first elastic member 42 is a spring.

[0044] The first rotating arm 11 is in the shape of a disk. Figure 8The first rotating arm 11 includes a rotating arm body 111 and a cover plate 112 connected to the rotating arm body 111. The rotating arm body 111 and the cover plate 112 together form a first inner cavity 110, wherein the first connecting portion 1112 extends outward from the outer peripheral side of the rotating arm body 111. The rotating arm body 111 and the cover plate 112 are separately arranged, so that the first rotating disk 12 and the driving mechanism 4 can be easily assembled in the first inner cavity 110.

[0045] The first rotating disk 12 is in the shape of a disk. Figure 7 The first rotating disk 12 is provided with a first shaft hole 122 for the rotating shaft 3 to pass through, and the first shaft hole 122 is located in the central area of ​​the first rotating disk 12 .

[0046] See also Figure 7 The first turntable 12 is provided with a guide groove 120, which is recessed inward from the first disk surface of the first turntable 12. The first disk surface is an inclined surface inclined relative to the radial cross-section of the first turntable 12, and the first tooth portion 121 protrudes outward from the second disk surface of the first turntable 12.

[0047] For details, see Fig.10 The guide groove 120 includes a groove bottom wall 1201 and a groove side wall 1202. The groove side wall 1202 is connected to the groove bottom wall 1201. The groove bottom wall 1201 is inclined relative to the radial section of the first rotating disk 12, that is, the groove bottom wall 1201 is inclined relative to the radial section of the first rotating arm 11. The driving member 41 is at least partially disposed in the guide groove 120 and can move in the guide groove 120. The side of the driving member 41 extending into the guide groove 120 is adapted to the groove bottom wall 1201 and the groove side wall 1202. Since the first side surface 4111 of the driving member 41 is adapted to the groove bottom wall 1201, the first side surface 4111 of the driving member 41 is an inclined surface inclined relative to the radial section of the first rotating arm 11. Through the inclined cooperation between the first side surface 4111 of the driving member 41 and the groove bottom wall 1201, the first rotating disk 12 can be subjected to an axial force during the movement of the driving member 41 along the radial direction of the first rotating arm 11. In the present invention, the moving direction of the driving member 41 and the moving direction of the first rotating disk 12 are in different directions, so that the installation position of the driving member 41 is conveniently set.

[0048] In this embodiment, the length direction of the driving member 41 is perpendicular to the axial direction of the rotating shaft 3, and the moving direction of the driving member 41 is perpendicular to the axial direction of the rotating shaft 3. Since the first turntable 12 moves along the length direction of the rotating shaft 3, the moving direction of the driving member 41 is also perpendicular to the moving direction of the first turntable 12.

[0049] Based on the retraction of the first turntable 12 by pressing the driving member 41, the width of the driving member 41 gradually increases from the pressing end to the supporting end along the axial direction of the shaft 3. It should be noted that the retraction of the first turntable 12 refers to the movement of the first turntable 12 away from the second rotating body 2, and the supporting end refers to the end connected to the first elastic member 42.

[0050] In the process of pressing the driving member 41, in order to prevent the driving member 41 from being separated from the first rotating disk 12, that is, to make the driving member 41 drive the first rotating disk 12 to retract, see Fig.10 Along the first direction, the width of the groove bottom wall 1201 is greater than the width of the groove opening 1200 of the guide groove 120, so that the driving member 41 and the first turntable 12 can be axially limited, wherein the first direction is perpendicular to the axial direction of the rotating shaft 3 and is also perpendicular to the length direction of the driving member 41.

[0051] The driving member 41 includes a second side surface 4112 connected to the first side surface 4111 . A ridge 410 is disposed at the connection between the first side surface 4111 and the second side surface 4112 . The guide groove 120 includes a receiving groove 120 b for receiving the ridge 410 .

[0052] In some embodiments, the guide groove 120 is a dovetail groove, see Fig.10 The groove side wall 1202 includes a first side wall 12021 and a second side wall 12022, the second side wall 12022 connects the first side wall 12021 and the groove bottom wall 1201, and the second side wall 12022 extends obliquely from the first side wall 12021 to the groove bottom wall 1201. The accommodating groove 120b includes a space enclosed by the second side wall 12022 and the groove bottom wall 1201. Of course, in other possible embodiments, the guide groove 120 may also be a T-shaped groove.

[0053] In some embodiments, see Figures 6 to 9 The first rotating body 1 includes two first rotating disks 12, which are distributed in a mirror image. The two first rotating disks 12 are correspondingly arranged on both sides of the driving member 41. The side of each first rotating disk 12 facing away from the driving member 41 is provided with a second rotating body 2. Accordingly, the driving member 41 is roughly in a trapezoidal shape. The two first side surfaces 4111 of the driving member 41 are both inclined surfaces inclined outward. The two second side surfaces 4112 of the driving member 41 are parallel to the axis of the driving member 41. The driving member 41 is provided with four convex ridges 410. By arranging the first rotating disks 12 on both sides of the driving member 41, the two first rotating disks 12 cooperate with the two second rotating bodies 2. After the cover body is closed relative to the box body, the second tooth portions 221 of the two second rotating bodies 2 are meshed with the first tooth portions 121 of the two first rotating disks 12, which is conducive to improving the locking stability between the cover body and the box body. Of course, in other possible embodiments, the first rotating body 1 can also include one first rotating disk 12, and one first rotating disk 12 cooperates with one second rotating body 2.

[0054] See also Figure 2 The first rotating disk 12 includes a tooth area 12a, which is a part of the second disk surface. The tooth area 12a is provided with a first tooth portion 121. The second rotating body 2 is provided with a limiting rib 222, which is spaced apart from the second tooth portion 221. The limiting rib 222 is used to abut against the first tooth portion 121 at the end of the tooth area 12a. The limiting rib 222 abuts against the first tooth portion 121 to control the rotation angle of the second rotating body 2, so that the second tooth portion 221 of the second rotating body 2 slides back and forth in the tooth area 12a of the first rotating disk 12.

[0055] In this embodiment, the tooth area 12a is fan-shaped, and the central angle of the tooth area 12a is not greater than the central angle of the area of ​​the first rotating disk 12 where the first tooth portion 121 is not provided. In other words, the area of ​​the tooth area 12a does not exceed half of the area of ​​the first rotating disk 12. Of course, in other possible embodiments, the setting of the limiting rib 222 can also be cancelled, and the second disk surface of the first rotating disk 12 is provided with the first tooth portion 121.

[0056] See also Fig.12 The limiting rib 222 and the second tooth portion 221 are arranged in the sector area 22a of the second rotating body 2, and the central angle of the tooth area 12a is not less than the central angle of the sector area 22a, so as to ensure that when the limiting rib 222 abuts against the first tooth portion 121 at one end of the tooth area 12a, the second tooth portion 221 is engaged with the first tooth portion 121 at the other end of the tooth area 12a, and the second tooth portion 221 does not separate from the tooth area 12a.

[0057] In this embodiment, the first tooth portion 121 is a ratchet, that is, the first tooth portion 121 is a one-way tooth. When the cover needs to be opened, since the first tooth portion 121 is a one-way tooth, the cover cannot be opened relative to the box body by simply moving the cover, and the first tooth portion 121 and the second tooth portion 221 need to be released by pressing the driving member 41, so that the cover and the box body are locked more stably in the closed state.

[0058] See also Figure 3 The second rotating body 2 includes a second rotating arm 21 and a second rotating disk 22. The second rotating arm 21 is provided with a second connecting portion 213, and the second connecting portion 213 is connected to the cover body. Figure 4 The second rotating arm 21 has a second inner cavity 210, and the second rotating disk 22 is arranged in the second inner cavity 210. The second rotating disk 22 is provided with a second tooth portion 221. The number of teeth of the second tooth portion 221 is less than the number of teeth of the first tooth portion 121. A tooth groove is formed between two adjacent first tooth portions 121, and the shape of the second tooth portion 221 is adapted to the tooth groove.

[0059] See also Figure 4In order to prevent the second rotating disk 22 and the second rotating arm 21 from rotating relative to each other, the second rotating arm 21 is provided with a slot 211, the slot 211 is connected to the second inner cavity 210, and the second rotating disk 22 is provided with a convex portion 223, and the convex portion 223 extends into the slot 211. Specifically, the second rotating disk 22 is provided with two symmetrical slots 211, and the slots 211 are formed by being recessed inward from the cavity wall of the second inner cavity 210.

[0060] In this embodiment, the first rotating body 1 and the two second rotating bodies 2 are assembled to form a spherical structure, which has a beautiful appearance and can also be applied to a charging box whose rotation position is an arc shape.

[0061] The first tooth portion 121 and the second tooth portion 221 are one-way teeth, and a third elastic member 24 is provided on the side of the second rotating disk 22 away from the first rotating disk 12, so that the first tooth portion 121 elastically abuts against the second tooth portion 221, so that when the first tooth portion 121 and the second tooth portion 221 are in meshing state, the second rotating disk 22 can rotate relative to the first rotating disk 12 in a second rotation direction opposite to the first rotation direction under the action of an external force. Optionally, the third elastic member 24 is a spring.

[0062] See also Figure 4 The second rotating body 2 includes a connecting member 23, which can be a bolt or a screw. The second rotating disk 22 is provided with a first hole 224, which is a countersunk hole. The second rotating arm 21 is provided with a boss 212 extending toward the second inner cavity 210, and the boss 212 is provided with a second hole 2120. The connecting member 23 is passed through the first hole 224 and connected to the second hole 2120. The third elastic member 24 is at least partially sleeved on the boss 212, and the two ends of the third elastic member 24 are respectively against the second rotating disk 22 and the cavity wall of the second inner cavity 210. When the second rotating disk 22 is subjected to an axial external force, the second rotating disk 22 can move toward the second inner cavity 210 by compressing the third elastic member 24. When the cover needs to be closed, two methods can be used. One is to press the driving member 41 to disengage the first tooth portion 121 from the second tooth portion 221, so that the second rotating body 2 rotates around the rotating shaft 3 to close the cover. The other method is to press the cover to drive the second turntable 22 to compress the third elastic member 24 to obtain a sliding space, so that the second tooth portion 221 slides relative to the first tooth portion 121 to close the cover.

[0063] In this embodiment, a plurality of protruding pillars 212 are provided and arranged in a triangle shape to prevent the second rotating disk 22 from tilting when compressing the third elastic member 24 .

[0064] See also Figure 4 and Figure 5The second rotating disk 22 is provided with a second shaft hole 225 for the shaft 3 to pass through, and the second rotating arm 21 is provided with a third shaft hole 214 for the shaft 3 to pass through.
