Description

Technical Field

[0001] This application relates to the field of electronic device accessories technology, specifically to a damping shaft structure and electronic device. Background Technology

[0002] Damping shafts are widely used in electronic products. A common damping shaft usually consists of a disc spring, a flat washer, a connecting shaft, and a locking nut. The damping effect is achieved by applying axial pressure to the disc spring and flat washer through the locking nut, which generates friction.

[0003] However, the damping shafts in related technologies typically have their rotation center inside the shaft. When applied to electronic devices, this can cause excessive gaps between the back panel and the main body, affecting the overall integrity of the electronic device. Summary of the Invention

[0004] The purpose of this application is to provide a damping shaft structure and electronic device with stronger overall integrity.

[0005] In a first aspect, embodiments of this application provide a damping shaft structure, including:

[0006] The base includes a wall, a receiving space with one end open, an arc-shaped guide rail disposed on the wall and extending from the opening into the receiving space, and a damping medium housed in the receiving space.

[0007] A rotating component is at least partially housed within a receiving space and is disposed in contact with a damping medium. The rotating component includes a rotating guide rail that is engaged with an arc-shaped guide rail. The rotating component is used to rotate around a rotation center along the arc-shaped guide rail.

[0008] The center of rotation is located on the outside of the rotating component, away from the receiving space.

[0009] In these embodiments of the present application, by setting the rotation center on the outside of the rotating part away from the receiving space, that is, by placing the rotation center externally, when subsequently assembled into an electronic device, the contact point between the main body and the back plate can be set at the rotation center. In this way, regardless of whether the damping shaft structure is in a closed or open state, the main body and the back plate are always in a contact state, resulting in stronger overall integrity.

[0010] According to some embodiments of the first aspect of this application, the base further includes a first stop protrusion, and the rotating member further includes a second stop protrusion;

[0011] The second stop protrusion is used to rotate along an arc-shaped trajectory under the drive of the rotating component, and the first stop protrusion is located on the movement trajectory of the second stop protrusion.

[0012] According to some embodiments of the first aspect of this application, the arc-shaped guide rail includes:

[0013] With the damping shaft structure in a closed state, one of the first stop protrusion and the second stop protrusion is positioned closer to the first end, and the other is positioned closer to the second end.

[0014] In these embodiments of the present application, by respectively providing the first stop protrusion and the second stop protrusion at the first end and the second end, the rotating member can obtain the maximum rotation angle, thereby enabling the electronic device to obtain the maximum opening angle between the main body and the back panel after subsequent installation on the electronic device.

[0015] According to some embodiments of the first aspect of this application, the rotating member includes an arcuate surface concentrically arranged with the arcuate guide rail, and a portion of the arcuate surface abuts against the damping medium.

[0016] In these embodiments of this application, due to the presence of the arc-shaped surface, the force on the damping medium can remain basically constant when the rotating component rotates to different angles. In this way, while stably providing frictional force, the wear of the damping medium can be reduced and the service life of the damping medium can be improved.

[0017] According to some embodiments of the first aspect of this application, the rotating member further includes a plurality of anti-slip teeth disposed on the arc-shaped surface, the plurality of anti-slip teeth being spaced apart along the rotation direction of the rotating member.

[0018] According to some embodiments of the first aspect of this application, the rotating member includes:

[0019] The main body has a rotating guide rail set on it, and the main body can be rotated relative to the arc-shaped guide rail.

[0020] A connector is attached to the body and extends out of the body; the connector is used to connect to the back plate.

[0021] According to some embodiments of the first aspect of this application,

[0022] The body includes a groove formed by recessing from the arc-shaped surface towards the center of rotation;

[0023] The connector includes an adapter and a connecting part. The adapter is connected to the groove, and the connecting part is connected to the adapter and extends out of the body.

[0024] According to some embodiments of the first aspect of this application, the surface of the adapter that is away from the groove and the body together form an arc-shaped surface.

[0025] According to some embodiments of the first aspect of this application, the damping medium includes:

[0026] Elastomers;

[0027] An avoidance surface is provided on the side of the elastic body near the rotation center, and the curvature of the avoidance surface is the same as that of the arc-shaped guide rail.

[0028] Secondly, embodiments of this application also provide an electronic device, including:

[0029] main body;

[0030] Back panel; and

[0031] As in any of the foregoing embodiments, the damping shaft structure has a base connected to the main body and a rotating component connected to the back plate;

[0032] One end of the back plate abuts against the main body, and the abutment position of the back plate against the main body overlaps with the rotation center.

[0033] The damping shaft structure and electronic device provided in the embodiments of this application have at least the following beneficial effects:

[0034] By setting the rotation center on the outside of the rotating part away from the receiving space, that is, by placing the rotation center externally, when assembling it into electronic equipment, the contact point between the main body and the back plate can be set at the rotation center. In this way, regardless of whether the damping shaft structure is in a closed or open state, the main body and the back plate will always be in contact, resulting in stronger overall integrity.

[0055] Please refer to the following: Figures 2 to 8This application provides a damping pivot structure 100, which includes a base 10 and a rotating member 20. The base 10 includes a wall 11, a receiving space 12 with an opening 101 at one end formed by the wall 11, an arc-shaped guide rail 13 formed by the wall 11 and extending from the opening 101 into the receiving space 12, and a damping medium 14 housed within the receiving space 12. The rotating member 20 is at least partially housed within the receiving space 12 and abuts against the damping medium 14. The rotating member 20 includes a rotating guide rail 21 engaged with the arc-shaped guide rail 13, and is used to rotate along the arc-shaped guide rail 13 around a rotation center O. The rotation center O is located on the outer side of the rotating member 20 away from the receiving space 12.

[0056] The base 10 is a support structure for the damping shaft structure 100, and is movably connected to the rotating component 20 and used to support the rotating component 20. During the installation of the damping shaft structure 100, the base 10 can be installed on the main body 200 and the rotating component 20 can be installed on the back plate 300; alternatively, the base 10 can be installed on the back plate 300 and the rotating component 20 can be installed on the main body 200, depending on the actual situation.

[0057] The base 10 can be installed onto the main body 200 or the back plate 300 by means of a snap-fit ​​connection, a pin connection, or a bolt and screw connection, depending on the actual situation. For example, in this embodiment, the base 10 has fixing lugs 102 on both sides corresponding to the receiving space 12. During the installation of the base 10, the fixing lugs 102 can be connected to the main body 200 or the back plate 300 using bolts or screws, thus achieving the installation of the base 10.

[0058] The base 10 includes wall portions 11. The wall portions 11 can be multiple plate-like structures extending in the same direction, collectively enclosing a receiving space 12 with one open end. Exemplarily, in some embodiments of this application, the base 10 may include a base plate, with multiple wall portions 11 extending in a direction perpendicular to the base plate, the multiple wall portions 11 and the base plate collectively enclosing the receiving space 12, and an opening 101 communicating with the receiving space 12 being formed at the end of the wall portion 11 away from the base plate.

[0059] In these embodiments of the present application, a fixed lug 102 may also be provided to connect with the base plate.

[0060] The arc-shaped guide rail 13 extends from the opening 101 into the receiving space 12. The function of the arc-shaped guide rail 13 is to provide guidance for the installation and use of the rotating part 20.

[0061] The arc-shaped guide rail 13 means that within the plane of a wall portion 11, the arc-shaped guide rail 13 is arc-shaped, and the extension direction of the arc-shaped guide rail 13 is from the wall portion 11 toward the receiving space 12.

[0062] In some embodiments of this application, there may be two arc-shaped guide rails 13, with the two arc-shaped guide rails 13 located on two opposite wall portions 11, and the two arc-shaped guide rails 13 coinciding in the extending direction. In this way, by using two arc-shaped guide rails 13 to guide the rotating member 20 together, the stability and reliability of the damping shaft structure 100 are improved.

[0063] The damping medium 14 is housed in the receiving space 12. In this embodiment, the damping medium 14 is connected to the base plate. After the rotating member 20 is installed, the rotating member 20 abuts against and presses against the damping medium 14. The damping medium 14 provides friction to the rotating member 20 so that the rotating member 20 can stop and be fixed at any angle.

[0064] For example, the damping medium 14 can be rubber, latex, plastic or other polymer materials.

[0065] The rotating guide rail 21 is adapted to the arc-shaped guide rail 13. That is, the rotating guide rail 21 is a groove structure adapted to the arc-shaped guide rail 13. During installation, one end of the rotating guide rail 21 with the groove structure is aligned with one end of the arc-shaped guide rail 13 so that the rotating guide rail 21 can be inserted into the arc-shaped guide rail 13.

[0066] Of course, in some embodiments of the application, the rotating guide rail 21 can be configured as a convex structure and the arc-shaped guide rail 13 as a groove structure, so that the rotating guide rail 21 can still be inserted into the arc-shaped guide rail 13.

[0067] During the operation of the damping shaft structure 100, the rotating component 20 can rotate around the rotation center O along the arc-shaped guide rail 13. For example, when the cross-section of the arc-shaped guide rail 13 along the extension direction is a circular arc, the rotation center O is the center of the circle containing the arc-shaped guide rail 13; when the cross-section of the arc-shaped guide rail 13 along the extension direction is an elliptical arc, the rotation center O is the midpoint of the line connecting the two foci of the ellipse containing the arc-shaped guide rail 13.

[0068] The rotation center O is located on the outside of the rotating part 20 away from the receiving space 12, which means that the rotation center O is located outside the receiving space 12. In this embodiment, the rotation center O is located on the side of the arc-shaped guide rail 13 away from the bottom plate.

[0069] By setting the rotation center O outside the accommodating space 12, in the application of the damping shaft structure 100, the base 10 can be connected to the main body 200, and the rotating component 20 can be connected to the back plate 300. One end of the back plate 300 abuts against the main body 200, and the abutment position of the back plate 300 and the main body 200 overlaps with the rotation center O. In this way, since the abutment position of the back plate 300 and the main body 200 overlaps with the rotation center O, no matter how the back plate 300 and the main body 200 rotate, they can always maintain abutment without gaps, thereby improving the overall integrity and aesthetics of the electronic device.

[0070] It should be noted that in these embodiments of this application, the rotation center O is a virtual rotating shaft structure. The rotation center O is positioned on the outside of the rotating component 20, away from the receiving space 12. This can be achieved by controlling the length of the arc-shaped guide rail 13. For example, when the arc-shaped guide rail 13 is a circular guide rail, its length can be set to be less than the circumference of the semicircle, thus ensuring that the rotation center O is located outside the receiving space 12.

[0071] In some embodiments of this application, the base 10 further includes a first stop protrusion 15; the rotating member 20 further includes a second stop protrusion 22. The second stop protrusion 22 is used to rotate along an arc-shaped trajectory under the drive of the rotating member 20, and the first stop protrusion 15 is located on the movement trajectory of the second stop protrusion 22.

[0072] By setting the first stop protrusion 15 to be located on the movement trajectory of the second stop protrusion 22, the first stop protrusion 15 provides a limit for the second stop protrusion 22.

[0073] In some embodiments of this application, the arc-shaped guide rail 13 includes a first end 131 and a second end 132 opposite to each other. In the closed state of the damping shaft structure 100, one of the first stop protrusion 15 and the second stop protrusion 22 is disposed near the first end 131 and the other is disposed near the second end 132.

[0074] In these embodiments of this application, one of the first stop protrusion 15 and the second stop protrusion 22 is disposed near the first end 131 and the other is disposed near the second end 132, that is, the first stop protrusion 15 and the second stop protrusion 22 are respectively disposed at both ends of the arc-shaped guide rail 13, so that the damping shaft structure 100 obtains the maximum opening and closing angle.

[0075] In some embodiments of this application, the rotating member 20 includes an arcuate surface 23 concentrically arranged with the arcuate guide rail 13, and a portion of the arcuate surface 23 abuts against the damping medium 14.

[0076] The concentric arrangement of the arc-shaped surface 23 and the arc-shaped guide rail 13 means that after the damping shaft structure 100 is assembled, the arc-shaped surface 23 can rotate along the rotation center O with the cooperation of the rotating guide rail 21 and the arc-shaped guide rail 13.

[0077] The presence of a portion of the curved surface 23 in contact with the damping medium 14 means that at least a portion of the curved surface 23 is in contact with the damping medium 14 to obtain a damping effect. For example, the curved surface 23 can be used to compress the damping medium 14, thereby increasing the friction between the curved surface 23 and the damping medium 14, so that the curved surface 23 and the damping medium 14 can maintain their relative positions unchanged without external interference.

[0078] In some embodiments of this application, the curvature of the arc surface 23 can be set to be consistent with the curvature of the arc guide rail 13. With this setting, no matter what angle the rotating member 20 rotates to, the squeezing force applied by the rotating member 20 to the damping medium 14 can remain unchanged, which further stabilizes the angle adjustment effect and extends the service life of the damping medium 14.

[0079] In some embodiments of this application, the rotating member 20 further includes a plurality of anti-slip teeth 24 disposed on the arc-shaped surface 23, the plurality of anti-slip teeth 24 being spaced apart along the rotation direction of the rotating member 20.

[0080] In these embodiments of the present application, by providing multiple anti-slip teeth 24, slippage between the arc-shaped surface 23 and the damping medium 14 can be avoided, further increasing the stability of the damping shaft structure 100.

[0081] In some embodiments of this application, the rotating member 20 includes a body 25 and a connecting member 26. A rotating guide rail 21 is disposed on the body 25, and the body 25 is rotatably disposed relative to the arc-shaped guide rail 13. The connecting member 26 is connected to the body 25 and extends out of the body 25, and the connecting member 26 is used to connect to the back plate 300.

[0082] The rotating guide rail 21 is set on the body 25, which means that regardless of whether the rotating guide rail 21 is a raised structure or a groove structure, it is connected to the body 25.

[0083] In these embodiments of this application, the connector 26 and the body 25 can be connected in a detachable manner. The assembly steps of the damping shaft structure 100 can be as follows: assemble the body 25 onto the arc-shaped guide rail 13 via the rotating guide rail 21, and then assemble the connector 26 onto the body 25 using screws or bolts. This facilitates assembly, and because the connector 26 extends beyond the body 25, it can limit the movement of the body 25, preventing it from rotating out along the arc-shaped guide rail 13 and improving the reliability of the damping shaft structure 100.

[0084] The curved surface 23 and anti-slip teeth 24 can be provided on the body 25 and / or the connector 26, and can be selected according to the actual situation.

[0085] In some embodiments of this application, the body 25 includes a groove 251 formed from the arcuate surface 23 toward the rotation center O; the connector 26 includes a transition portion 261 and a connecting portion 262, the transition portion 261 is connected to the groove 251, and the connecting portion 262 is connected to the transition portion 261 and extends out of the body 25 from the transition portion 261.

[0086] The connection of the adapter 261 to the groove 251 means that the adapter 261 is housed in the groove 251, the adapter 261 abuts against the bottom of the groove 251, and the surface of the adapter 261 away from the bottom of the groove 251 matches the shape of the body 25.

[0087] For example, in some embodiments of this application, the body 25 has an arcuate surface 23, and the surface of the transition portion 261 away from the bottom of the groove 251 is the arcuate surface 23, or a surface that naturally transitions with the arcuate surface 23, so as to ensure the contact area between the rotating member 20 and the damping medium 14, thereby ensuring the friction force generated between the rotating member 20 and the damping medium 14.

[0088] In some embodiments of this application, the bottom surface of the groove 251 can be flat, which facilitates the insertion of the connector 26 after the main body 25 is connected to the base 10. In some embodiments of this application, in order to facilitate the connection between the adapter 261 and the main body 25, the bottom surface of the groove 251 can also be wavy. In this way, the wavy bottom surface can play a foolproof role and is more conducive to the connection between the adapter 261 and the main body 25.

[0089] In some embodiments of this application, the surface of the adapter 261 facing away from the groove 251 and the body 25 together form an arcuate surface 23.

[0090] In some embodiments of this application, the damping medium 14 includes an elastic body 141 and a relief surface 142 disposed on the side of the elastic body 141 near the rotation center O, the curvature of the relief surface 142 being the same as the curvature of the arc-shaped guide rail 13.

[0091] The above are merely specific embodiments of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the scope of the claims.
