Description

Technical Field

[0001] This utility model relates to the field of electronic equipment mechanical technology, and in particular to a pivot with an auxiliary torque structure. Background Technology

[0002] Currently, portable electronic devices (such as laptops) generally employ a pivot-connected, closable design to meet both display needs during use and portability requirements when not in use. In this design, the pivot is a critical connecting component, and its performance directly impacts the user experience and reliability of the device.

[0003] Taking a single-axis pivot as an example, existing technologies primarily achieve the opening and closing function of the display screen by applying torsional interference to a single axis through a circular structure. To optimize the user experience, the interference force of the circular structure on the single axis is usually reduced, resulting in a smoother opening feel. However, this design optimization has a significant technical flaw: when the interference force is reduced to a certain level, the torque generated by the pivot will be insufficient to balance the self-weight torque of the display screen, causing the device to fail to maintain stable screen positioning at small opening angles (such as 30°). This technical problem not only significantly reduces the user experience but may also cause mechanical damage to the display screen and host system due to unexpected closure or shaking of the screen, affecting the product's lifespan and reliability. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems of the prior art and provide a pivot with an auxiliary torque structure.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A pivot with an auxiliary torque structure includes a pivot body, one end of which is movably connected to a first connector, and a second connector is rotatably connected to the pivot body.

[0007] The other end of the pivot body is connected to a torsion spring limiting block, which has a limiting section and an arc-shaped sliding opening.

[0008] A torsion spring is fitted on the pivot body. One end of the torsion spring is movably connected to the torsion spring limiting block, and this end can slide in the arc-shaped sliding opening. The other end of the torsion spring is connected to the second connecting piece.

[0009] Furthermore, one end of the torsion spring is laterally bent and movably connected to the torsion spring limiting block, and this end of the torsion spring passes through the arc-shaped sliding opening.

[0010] Furthermore, the second connector has a linkage bend extending toward the torsion spring limiting block;

[0011] The other end of the torsion spring first extends radially through the back of the connecting bending piece, then bends laterally at the top of the connecting bending piece to the front of the connecting bending piece and extends away from the torsion spring limiting block.

[0012] Furthermore, a positioning recess is formed on the back side of the connection between the linkage bending piece and the second connector, which is concave towards its front side.

[0013] Furthermore, the end of the linkage bending piece has a bending anti-detachment section extending toward its back side.

[0014] Furthermore, the connection between the top end of the linkage bending piece and the second connecting member, and the connection between the bottom end of the linkage bending piece and the second connecting member, both have limiting grooves;

[0015] The other end of the torsion spring is located in the limiting groove when it bends at the connecting bending piece.

[0016] Furthermore, a torsion spring anti-detachment plate is sleeved on the pivot body to prevent the torsion spring limiting block from detaching from the pivot body.

[0017] Furthermore, an anti-detachment ring groove is provided at the other end of the pivot body;

[0018] The torsion spring anti-detachment plate has a radially penetrating anti-detachment opening, and the inner ring end of the torsion spring anti-detachment plate extends inward to provide an anti-detachment insertion section into which an anti-detachment ring groove can be inserted.

[0019] Furthermore, the second connector is connected to a torque envelope that can interfere with the pivot body, and the torque envelope has a radially penetrating torque opening.

[0020] Furthermore, a stop structure is provided on the pivot body;

[0021] The torsion envelope has a stop notch that can cooperate with the stop structure.

[0022] This invention has the following beneficial effects: While ensuring smooth opening and closing operation of the display screen, it effectively solves the problem of unstable positioning caused by insufficient torque in traditional pivots by adding an auxiliary torque adjustment mechanism, and optimizes the closing buffer performance, significantly improving the user experience and structural reliability of the device, as detailed below:

[0023] 1. Segmented torque control for optimized opening feel: In the initial stage of opening the display screen, one end of the torsion spring slides freely within the arc-shaped sliding opening. At this time, the torsion spring is not obstructed or interfered with, and will not apply additional torque to the pivot body, thus ensuring a smooth opening feel for the display screen. When the display screen is opened to a specific angle (such as a small angle range), the torsion spring slides to the limit position of the arc-shaped sliding opening and is blocked by the torsion spring limit block and limit segment, thereby generating elastic deformation, providing additional support torque to the pivot body, effectively preventing the display screen from accidentally falling or shaking due to its own weight, and improving the stability of opening at small angles.

[0024] 2. Closed buffer protection to reduce mechanical wear: During the closing process of the display screen, the torsion spring also slides freely first to avoid generating resistance too early and affecting the closing operation; when the display screen is close to being completely closed, the torsion spring slides to the limit position of the other end of the arc-shaped slide and is blocked and deformed, generating buffer torque to reduce the impact between the display screen and the host system, reduce the risk of mechanical wear, and extend the service life of the equipment.

[0025] 3. High structural adjustability to adapt to different needs: By adjusting the arc length of the arc-shaped sliding opening and its relative circumferential position with the second connecting piece, the angle range at which the torsion spring begins to provide torque can be precisely controlled, ensuring that appropriate support or buffering force can be provided during small-angle opening or closing stages to meet the design requirements of different products.

[0032] To enable those skilled in the art to better understand this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] like Figures 1 to 8 As shown, a pivot with an auxiliary torque structure includes a pivot body 1, one end of which is connected to a first connecting member 2, and a second connecting member 3 is rotatably connected to the pivot body 1.

[0035] The other end of the pivot body 1 is connected to a torsion spring limiting block 4, which has a limiting section 6 and an arc-shaped sliding opening 7.

[0036] A torsion spring 5 is fitted on the pivot body 1. One end of the torsion spring 5 is movably connected to the torsion spring limiting block 4, and this end can slide in the arc-shaped sliding opening 7. The other end of the torsion spring 5 is connected to the second connecting member 3.

[0037] In this embodiment, the first connector 2 may be provided with a plurality of first connection holes 19, which are connected to the host system end through the first connection holes 19; the second connector 3 may be provided with a plurality of second connection holes 20, which are connected to the display screen end through the second connection holes 20.

[0038] In application, rotating the second connector 3 (towards the opening of the display screen) causes the torsion spring 5 to rotate along with it. One end of the torsion spring 5 slides within the arc-shaped sliding opening 7. During this process, the torsion spring limiting block 4 and the limiting segment 6 do not obstruct or interfere with the torsion spring 5, therefore, the torsion spring 5 does not provide torque to the pivot 1. Continuing to rotate the second connector 3, causing one end of the torsion spring 5 to slide to the limit position of one end of the arc-shaped sliding opening 7 and maintain its rotational tendency, the torsion spring 5 undergoes elastic deformation under the obstruction of the torsion spring limiting block 4 and the limiting segment 6, thus providing torque to the pivot 1. In this way, without affecting the opening feel, torque is provided to offer additional support to the display screen, preventing damage to the display screen at small opening angles. If the end of the display screen is accidentally rotated or shaken, the second connector 3 is rotated in the opposite direction (towards closing the display screen end). As the second connector 3 rotates in the opposite direction, one end of the torsion spring 5 also slides in the opposite direction within the arc-shaped sliding opening 7. During this process, if the torsion spring limiting block 4 and limiting segment 6 do not obstruct or interfere with the torsion spring 5, the torsion spring 5 will not provide torque to the pivot body 1. When the second connector 3 is rotated in the opposite direction, causing one end of the torsion spring 5 to slide to the limit position of the other end of the arc-shaped sliding opening 7 and maintaining this rotational trend, the torsion spring 5 will also provide sufficient torque to the pivot body 1 due to elastic deformation to support the display screen end. In this way, it can play an additional buffering role when closing the display screen end, reducing the mutual wear between the display screen end and the host system end.

[0039] The arc length of the arc-shaped slide 7 and the relative circumferential position of the arc-shaped slide 7 and the second connecting piece 3 can be set according to the required requirements to ensure that the torsion spring 5 provides torque to the pivot body 1 to provide support when the opening angle is small; it can also ensure that the torsion spring 5 provides torque to the pivot body 1 to provide buffering when the display screen end is closed to the host system end.

[0040] To achieve a stable slidable connection between the torsion spring 5 and the arc-shaped sliding opening 7, preferably, one end of the torsion spring 5 is laterally bent and movably connected to the torsion spring limiting block 4, and this end of the torsion spring 5 passes through the arc-shaped sliding opening 7.

[0041] To achieve the linkage connection between the torsion spring 5 and the second connecting member 3, preferably, the second connecting member 3 has a linkage bending piece 8 extending toward the torsion spring limiting block 4;

[0042] The other end of the torsion spring 5 first extends radially through the back of the connecting bending piece 8, then bends laterally at the top of the connecting bending piece 8 to the front of the connecting bending piece 8 and extends away from the torsion spring limiting block 4.

[0043] In this embodiment, the direction in which the display screen is opened is the back side of the bending piece 8, and the direction in which the display screen is closed is the front side of the bending piece 8.

[0044] To improve the stability of the linkage between the torsion spring 5 and the second connecting member 3, preferably, a positioning recess 21 is formed on the back side of the connection between the linkage bending piece 8 and the second connecting member 3, which is concave towards its front side. When the other end of the torsion spring 5 passes over the back side of the linkage bending piece 8, that end of the torsion spring 5 is located at the positioning recess 21.

[0045] To prevent the torsion spring 5 from accidentally detaching from the second connector 3, preferably, the end of the linkage bending piece 8 has a bending anti-detachment section 18 extending toward its back side.

[0046] Preferably, the connection between the top end of the connecting bending piece 8 and the second connecting member 3, and the connection between the bottom end of the connecting bending piece 8 and the second connecting member 3, both have limiting grooves 9;

[0047] The other end of the torsion spring 5 is located in the limiting groove 9 when it is bent at the connecting bending piece 8.

[0048] The setting of the limiting groove 9 can improve the stability of the linkage between the torsion spring 5 and the second connecting piece 3.

[0049] Preferably, a torsion spring anti-detachment plate 10 is sleeved on the pivot body 1 to prevent the torsion spring limiting block 4 from detaching from the pivot body 1.

[0050] In this embodiment, under the support of the torsion spring 5, the torsion spring limiting block 4 tends to move away from the second connecting member 3, while the torsion spring anti-detachment plate 10 can prevent the torsion spring limiting block 4 from undergoing the aforementioned axial displacement.

[0051] Preferably, the other end of the pivot body 1 is provided with an anti-detachment ring groove 11;

[0052] The torsion spring anti-detachment plate 10 has a radially penetrating anti-detachment opening 12, and the inner ring end of the torsion spring anti-detachment plate 10 has an anti-detachment insertion section 13 that can be inserted into the anti-detachment ring groove 11.

[0053] In this embodiment, the anti-detachment insertion section 13 and the anti-detachment ring groove 11 cooperate to lock the extreme position of the outward axial displacement of the torsion spring limiting block 4. The anti-detachment opening 12 facilitates the fitting of the torsion spring anti-detachment plate 10 onto the anti-detachment ring groove 11.

[0054] Preferably, the second connector 3 is connected to a torque envelope 14 that can interfere with the pivot body 1, and the torque envelope 14 has a radially through torque opening 15.

[0055] When the second connecting piece 3 is rotated, the torque envelope 14 and the torque opening 15 can generate an appropriate interference torque on the pivot body 1 to play a basic positioning and support role.

[0056] Preferably, a stop structure 16 is provided on the pivot body 1;

[0057] The torsion circle 14 has a stop notch 17 that can cooperate with the stop structure 16.

[0058] In this embodiment, the rotation angle of the second connecting member 3 can be limited by the cooperation between the stop notch 17 and the stop structure 16, thus preventing excessive rotation. In addition, under the support of the torsion spring 5, the second connecting member 3 tends to move away from the torsion spring limiting block 4, and the stop structure 16 can prevent the second connecting member 3 from undergoing the aforementioned axial displacement.

[0059] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, other embodiments derived without departing from the technical solution of the present invention should be included within the protection scope of the present invention.
