[0021] A notebook computer includes the above-mentioned notebook computer hinge structure.

[0022] Beneficial effects of the utility model:

[0023] The utility model provides a notebook computer hinge structure and a notebook computer. The notebook computer hinge structure includes a hinge, a first support frame, a second support frame, and a torque adjustment structure. The first support frame is fixedly connected to the hinge. The second support frame is rotatably mounted on the hinge. The torque adjustment structure includes a first adjustment sleeve, a second adjustment sleeve, a first elastic member, a second elastic member, and a locking member. The first adjustment sleeve is rotatably mounted on the hinge. The first adjustment sleeve is provided with a connecting portion that fixedly connects the first adjustment sleeve and the second support frame and separates the first adjustment sleeve and the second support frame along the axial direction of the hinge. The second adjustment sleeve is mounted on the hinge and can move along the axial direction of the hinge. The first elastic member is mounted on the hinge. One end of the first elastic member abuts the second support frame, and the other end abuts the first adjustment sleeve. The second elastic member is mounted on the hinge. The locking member is detachably connected to the hinge. One end of the second elastic member abuts the second adjustment sleeve, and the other end abuts the locking member. Of the two adjacent end surfaces of the first adjustment sleeve and the second adjustment sleeve, one is provided with a convex block and the other is provided with a groove; the convex block can be inserted into the groove and can abut against the end surface where the groove is located.

[0024] When the first and / or second support frames drive the rotating shaft to rotate about its central axis, the second adjustment sleeve is driven to rotate synchronously, thereby driving the protrusion to engage with the groove or abut the end face where the groove is located. When the protrusion is engaged with the groove, the force applied to the second support frame by the torque adjustment structure is minimal; when the protrusion rotates from the groove to the end face where the groove is located, the force applied to the second support frame by the torque adjustment structure gradually increases; when the protrusion completely abuts the end face where the groove is located, the force applied to the second support frame by the torque adjustment structure is maximum; and when the protrusion rotates from the end face where the groove is located into the groove, the force applied to the second support frame by the torque adjustment structure gradually decreases. Therefore, according to the actual use needs of the user, when the laptop is in the closed state, the protrusion completely abuts the end face where the groove is located, so that the laptop can be firmly held in the closed state. Or, according to the actual use needs of the user, when the laptop is in the open state, the protrusion completely abuts the end face where the groove is located, so that the laptop opening angle is not easily changed due to external vibration or accidental touch. This can effectively improve the user experience.

[0025] By providing a connecting portion on the first adjustment sleeve, the connecting portion fixedly connects the first adjustment sleeve and the second support frame and separates the first adjustment sleeve and the second support frame along the axial direction of the rotating shaft, when the protrusion rotates from the groove to the end face where the groove is located, the connection between the connecting portion and the first adjustment sleeve body can undergo slight deformation, causing the portion of the first adjustment sleeve that is mounted on the rotating shaft to slightly move along the axial direction of the rotating shaft toward the first elastic member, thereby effectively reducing the wear of the protrusion and / or the groove, thereby effectively improving the service life of the laptop computer hinge structure. Secondly, by providing a first elastic member between the second support frame and the first adjustment sleeve, when the portion of the first adjustment sleeve that is mounted on the rotating shaft slightly moves along the axial direction of the rotating shaft toward the first elastic member, the first elastic member is compressed. Therefore, when the protrusion rotates from the end face where the groove is located into the groove, the elastic restoring force of the first elastic member can drive the first adjustment sleeve to return to its original state, thereby effectively reducing the shaking of the computer screen caused by suddenly opening the computer screen, thereby further improving the user experience.

[0026] Secondly, compared with the prior art, the notebook computer hinge structure does not require a locking rod, and effectively simplifies the structures of the first adjustment sleeve and the first elastic member.

[0027] Therefore, the laptop computer hinge structure has a simple structure, a small number of parts, a small size and a light weight, which effectively reduces the cost; secondly, by adopting the laptop computer hinge structure, the user experience can be effectively improved; thirdly, the service life of the laptop computer hinge structure is effectively improved.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0043] like Figure 1-4As shown, the present invention provides a laptop computer hinge structure, comprising a hinge 1, a first support frame 2, a second support frame 3, and a torque adjustment structure 4. The first support frame 2 is fixedly connected to the hinge 1. The second support frame 3 is rotatably mounted on the hinge 1. The torque adjustment structure 4 comprises a first adjustment sleeve 41, a second adjustment sleeve 42, a first elastic member 43, a second elastic member 44, and a locking member 45. The first adjustment sleeve 41 is rotatably mounted on the hinge 1. The first adjustment sleeve 41 has a connecting portion 411 that fixedly connects the first adjustment sleeve 41 to the second support frame 3 and separates the first adjustment sleeve 41 from the second support frame 3 along the axial direction of the hinge 1. The second adjustment sleeve 42 is mounted on the hinge 1 and is movable along the axial direction of the hinge 1. The first elastic member 43 is mounted on the hinge 1. One end of the first elastic member 43 abuts the second support frame 3, and the other end abuts the first adjustment sleeve 41. The second elastic member 44 is mounted on the hinge 1. The locking member 45 is detachably connected to the hinge 1. One end of the second elastic member 44 abuts the second adjustment sleeve 42, and the other end abuts the locking member 45. Of the two adjacent end surfaces of the first and second adjustment sleeves 41 and 42, one has a protrusion 421, and the other has a groove 412. The protrusion 421 can be inserted into the groove 412 and can abut the end surface where the groove 412 is located.

[0044] It can be understood that, along the axial direction of the rotating shaft 1, the portion of the second support 3 that is sleeved on the rotating shaft 1, the first elastic member 43, the portion of the first adjustment sleeve 41 that is sleeved on the rotating shaft 1, the second adjustment sleeve 42, the second elastic member 44, and the locking member 45 are sequentially distributed. The first elastic member 43 and the second elastic member 44 are both in a compressed state.

[0045] When the first support frame 2 and / or the second support frame 3 drive the rotating shaft 1 to rotate around its own central axis, the second adjustment sleeve 42 is driven to rotate synchronously, thereby driving the protrusion 421 to be inserted into the groove 412 or to abut the end surface where the groove 412 is located. When the protrusion 421 is inserted into the groove 412, the force applied to the second support frame 3 by the torsion adjustment structure 4 is the smallest; when the protrusion 421 rotates from the groove 412 to the end surface where the groove 412 is located, the force applied to the second support frame 3 by the torsion adjustment structure 4 gradually increases; when the protrusion 421 completely abuts the end surface where the groove 412 is located, the force applied to the second support frame 3 by the torsion adjustment structure 4 is the largest; when the protrusion 421 rotates from the end surface where the groove 412 is located into the groove 412, the force applied to the second support frame 3 by the torsion adjustment structure 4 gradually decreases. Therefore, according to the user's actual usage needs, when the laptop is closed, the protrusion 421 can be configured to completely abut the end surface where the groove 412 is located, so that the laptop can be securely held in the closed state. Alternatively, when the laptop is opened, the protrusion 421 can be configured to completely abut the end surface where the groove 412 is located, so that the laptop's opening angle is not easily changed due to external vibration or accidental touch. This can effectively improve the user experience.

[0046] By providing a connecting portion 411 on the first adjustment sleeve 41, the connecting portion 411 fixedly connects the first adjustment sleeve 41 and the second support frame 3 and separates the first adjustment sleeve 41 and the second support frame 3 along the axial direction of the rotating shaft 1. During the process of the protrusion 421 rotating from the groove 412 to the end face where the groove 412 is located, the connection between the connecting portion 411 and the main body of the first adjustment sleeve 41 can undergo a slight deformation, so that the part of the first adjustment sleeve 41 that is sleeved on the rotating shaft 1 moves slightly along the axial direction of the rotating shaft 1 toward the direction close to the first elastic member 43, thereby effectively reducing the wear of the protrusion 421 and / or the groove 412, thereby effectively improving the service life of the notebook computer hinge structure. Secondly, by arranging the first elastic member 43 between the second support frame 3 and the first adjustment sleeve 41, the first elastic member 43 is compressed during the process in which the part of the first adjustment sleeve 41 that is sleeved on the rotating shaft 1 moves slightly along the axial direction of the rotating shaft 1 toward the first elastic member 43. Therefore, when the protrusion 421 rotates from the end surface where the groove 412 is located toward the inside of the groove 412, the elastic restoring force of the first elastic member 43 can drive the first adjustment sleeve 41 to return to its initial state, thereby effectively reducing the shaking of the computer screen caused by suddenly opening the computer screen, thereby further improving the user experience.

[0047] Secondly, compared with the prior art, the notebook computer hinge structure does not require a locking rod, and effectively simplifies the structures of the first adjustment sleeve 41 and the first elastic member 43 .

[0048] Therefore, the laptop computer hinge structure has a simple structure, a small number of parts, a small size and a light weight, which effectively reduces the cost; secondly, by adopting the laptop computer hinge structure, the user experience can be effectively improved; thirdly, the service life of the laptop computer hinge structure is effectively improved.

[0049] Specifically, in this embodiment, Figure 1-4 As shown, a groove 412 is provided on the end surface of the first adjustment sleeve 41 near the second adjustment sleeve 42, and a bump 421 is provided on the end surface of the second adjustment sleeve 42 near the first adjustment sleeve 41. As an alternative, a bump 421 is provided on the end surface of the first adjustment sleeve 41 near the second adjustment sleeve 42, and a groove 412 is provided on the end surface of the second adjustment sleeve 42 near the first adjustment sleeve 41.

[0050] Specifically, in this embodiment, the first support frame 2 is fixedly connected to the rotating shaft 1 by riveting or the like. As an alternative, the first support frame 2 can also be fixedly connected to the rotating shaft 1 by threaded connection or the like.

[0051] Specifically, a shoulder is provided on the outer periphery of the rotating shaft 1 , which can limit the location of the second support 3 along the axial direction of the rotating shaft 1 .

[0052] Specifically, if Figure 4 As shown, the outer circumference of the rotating shaft 1 is recessed with an axially extending sliding groove, which forms a first sliding plane. The inner circumferential wall of the second adjustment sleeve 42 is formed with a second sliding plane 422, which extends axially to both end surfaces of the second adjustment sleeve 42. When the second adjustment sleeve 42 is mounted on the rotating shaft 1, the first sliding plane and the second sliding plane 422 come into surface contact, limiting the second adjustment sleeve 42 to axial movement of the rotating shaft 1 and preventing relative rotation.

[0053] Preferably, the first adjustment sleeve 41 is loosely sleeved on the rotating shaft 1 , so that the connection portion 411 is slightly deformed at the connection with the first adjustment sleeve 41 body, and the first elastic member 43 returns to its original state under the elastic restoring force.

[0054] More preferably, Figure 1-3 As shown, the connecting portion 411 forms an obtuse angle with the axial end surface of the first adjustment sleeve 41. Compared with the connecting portion 411 forming a right angle or an acute angle with the axial end surface of the first adjustment sleeve 41, the structural strength of the first adjustment sleeve 41 can be improved.

[0055] Further preferably, in this embodiment, the connecting portion 411 is integrally formed with the first adjustment sleeve 41. This can improve the structural strength of the first adjustment sleeve 41 and reduce the number of parts.

[0056] Specifically, in this embodiment, the connecting portion 411 is welded to the second support frame 3, facilitating the installation of the first elastic member 43 on the rotating shaft 1. As an alternative, the first adjustment sleeve 41, the connecting portion 411, and the second support frame 3 are integrally formed, thereby reducing the number of parts.

[0057] Specifically, the first elastic member 43 is an open ring, and the two free ends of the open ring are spaced apart along the axial and circumferential directions of the rotating shaft 1. One free end thereof abuts against the second support frame 3, and the other free end abuts against the first adjustment sleeve 41. As an alternative, the first elastic member 43 is a cylindrical spring. As another alternative, the first elastic member 43 is a disc spring. It is understandable that, for the first adjustment sleeve 41, the connecting portion 411 and the second support frame 3 being integrally formed, the first elastic member 43 is selected from an open ring. This facilitates the assembly of the first elastic member 43 to the rotating shaft 1. For the welding of the connecting portion 411 to the second support frame 3, the first elastic member 43 is selected from an open ring, a cylindrical spring or a disc spring, etc.

[0058] Specifically, the second elastic member 44 is a cylindrical spring. As an alternative, the second elastic member 44 includes a plurality of disc springs sequentially distributed along the axial direction of the rotating shaft 1 .

[0059] Preferably, if Figure 3 and Figure 4 As shown, the groove 412 is an arc-shaped groove and the protrusion 421 is an arc-shaped protrusion. This can improve the stability of the notebook computer when the first support frame 2 and / or the second support frame 3 drive the shaft 1 to rotate around its own central axis.

[0060] More preferably, Figure 3 and Figure 4 As shown, there are two grooves 412, spaced apart along the circumference of the first adjustment sleeve 41; there are two protrusions 421, with the two grooves 412 corresponding to the two protrusions 421. It is understood that the spacing angle of the two grooves 412 along the circumference of the first adjustment sleeve 41 is set based on the maximum opening and closing angle of the computer screen.

[0061] Specifically, the locking member 45 is a nut, which is threadedly connected to the shaft 1. By screwing the nut, the force applied to the second support 3 can be adjusted, thereby further improving the user experience of the notebook computer shaft structure.

[0062] Specifically, if Figure 1 、 Figure 2 and Figure 5As shown, the laptop hinge structure also includes a rotation limiter 5, which is fixedly mounted on the hinge 1 and has two circumferentially spaced limiting surfaces 51. These two limiting surfaces 51 are used to limit the rotation angle range of the hinge 1. This effectively prevents damage to the laptop caused by excessive flipping of the computer screen. It will be understood that the circumferential spacing between the two limiting surfaces 51 is determined based on the maximum opening and closing angle of the computer screen.

[0063] Furthermore, the rotation limiting member 5 is interference-fitted on the rotating shaft 1. Alternatively, the rotation limiting member 5 is fixedly fitted on the rotating shaft 1 by a key connection.

[0064] Furthermore, a shaft shoulder is provided on the outer periphery of the rotating shaft 1 , which can limit the setting position of the rotation limiting member 5 along the axial direction of the rotating shaft 1 .

[0065] Preferably, in this embodiment, along the axial direction of the rotating shaft 1, the rotation limiting member 5 is away from the first elastic member 43 relative to the portion of the second support frame 3 that is rotatably sleeved on the rotating shaft 1. The rotation limiting member 5 is located between the portion of the first support frame 2 fixedly connected to the rotating shaft 1 and the portion of the second support frame 3 that is rotatably sleeved on the rotating shaft 1.

[0066] The present invention also provides a notebook computer, comprising the above-mentioned notebook computer hinge structure. By adopting the above-mentioned notebook computer hinge structure, the opening and closing performance of the notebook computer can be effectively improved.

[0067] Specifically, there are two notebook computer hinge structures, which are located on both sides of the notebook computer along the length direction and are symmetrically distributed.

[0068] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
