Description
Technical Field
[0001] This utility model relates to the field of electronic equipment mechanical technology, and in particular to a pivot with a concealed stop structure. Background Technology
[0002] In the structural design of existing electronic devices (such as laptops), the host system and the display screen are typically opened and closed relative to each other via a pivot. This design satisfies the screen's visibility requirements during operation and facilitates storage and portability when the device is not in use. Specifically, the pivot, as a connecting component, allows the display screen to rotate around it as an axis, thereby opening and closing the screen.
[0003] To ensure that the display screen is not damaged by excessive rotation during operation, existing technology typically incorporates a stop structure on the pivot. For example, such as... Figure 1 As shown, a typical stop structure includes a stop protrusion 22 on a fixed support 21 and a stop notch 23 on a rotating shaft 24 that mates with the stop protrusion. Although this mechanical stop method can provide a reliable limiting function, it relies on the physical interference between the exposed protrusion and the groove, requiring sufficient structural strength to ensure long-term stability and durability, and therefore often requires a large space.
[0004] However, as electronic devices (especially laptops) become thinner and lighter, the design contradictions of traditional stop structures are becoming increasingly apparent: their large size limits further reduction in the overall size of the device, making it difficult to meet market demands for portability and compact design. Therefore, there is an urgent need for a new stop structure solution that can both ensure the reliability of the stop function and optimize space utilization. Utility Model Content
[0005] The purpose of this invention is to overcome the aforementioned problems of the prior art and to provide a pivot with a concealed stop structure.
[0006] The objective of this utility model is mainly achieved through the following technical solutions:
[0007] A pivot with a concealed stop structure includes a pivot body, a first connecting member that is movably connected to the pivot body, and a second connecting member that is sleeved on the pivot body and can rotate relative to the pivot body.
[0008] The second connector has a recessed stop groove.
[0009] A stop ring is connected to the pivot body, and the stop ring is provided with a stop protrusion that can be inserted into the stop groove and slide relative to the stop groove.
[0010] Furthermore, the stop groove is arc-shaped.
[0011] Furthermore, several concave grease grooves are provided on both sides of the stop ring.
[0012] Furthermore, the side of the second connector is provided with several recessed grease grooves.
[0013] Furthermore, the pivot body has a first linkage connecting section, a partition section, and a second linkage connecting section connected in sequence;
[0014] The outer diameters of both the first and second linkage connecting sections are smaller than the outer diameter of the separating section.
[0015] Furthermore, the first connector is sleeved onto the first linkage connecting section;
[0016] The second connector is sleeved on the second linkage connecting section, and the stop ring is located between the separating section and the second connector;
[0017] An adjusting nut is threadedly connected to the end of the second linkage section;
[0018] An interference component is also provided between the second connector and the adjusting nut on the pivot body.
[0019] Furthermore, the interference assembly includes two friction plates and a plurality of interference plates located between the two friction plates.
[0020] Furthermore, both sides of the friction plate are provided with several concave friction grease grooves.
[0021] Furthermore, both sides of the first linkage connecting segment and both sides of the second linkage connecting segment have linkage planes.
[0022] Furthermore, the first connector has a plurality of first connection holes;
[0023] The second connector has several second connection holes.
[0024] This invention offers the following advantages: When the first connector rotates relative to the second connector, the engagement of the stop protrusion and the stop groove precisely limits the rotation angle, effectively preventing excessive rotation of the display screen and ensuring the stability and lifespan of the device. By integrating the stop groove onto the second connector and concealing the stop protrusion, the strength of the stop structure is maintained while significantly reducing the space occupied by traditional exposed stop structures, which is beneficial for the slim and lightweight design of electronic devices. Furthermore, the concealed stop structure design reduces exposed mechanical structures, making the pivot more streamlined and aesthetically pleasing, in line with modern electronic product industrial design trends.

[0033] 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.
[0034] Example 1
[0035] like Figures 1 to 7 As shown, the pivot with a concealed stop structure includes a pivot body 1, a first connecting member 4 that is movably connected to the pivot body 1, and a second connecting member 5 that is sleeved on the pivot body 1 and can rotate relative to the pivot body 1.
[0036] The second connector 5 has a recessed stop groove 6;
[0037] A stop ring 2 is connected to the pivot body 1. The stop ring 2 is provided with a stop protrusion 3 that is inserted into the stop groove 6 and can slide relative to the stop groove 6.
[0038] Preferably, the first connector 4 has a plurality of first connection holes 16;
[0039] The second connector 5 has several second connection holes 17.
[0040] In this embodiment, the first connector 4 can be connected to the display screen through the first connection hole 16, and the second connector 5 can be connected to the host system through the second connection hole 17.
[0041] When the first connector 4 (the display screen end) is rotated, the engagement between the stop protrusion 3 and the stop groove 6 limits the rotation angle of the first connector 4, thus preventing excessive rotation of the display screen end. The stop groove 6 is located on the second connector 5, while the stop protrusion 3 is concealed. This design reduces the space occupied by the stop structure while ensuring sufficient stop strength, and also achieves an aesthetically pleasing effect.
[0042] like Figure 7 As shown, in order to satisfy the movement trajectory of the first connector 4 relative to the second connector 5, the stop groove 6 should be arc-shaped.
[0043] Preferably, both sides of the stop ring 2 are provided with a plurality of concave stop grease grooves 13;
[0044] Preferably, the second connector 5 has a plurality of recessed connecting grease grooves 14 on its side, and the stop groove 6 is provided on one side of the second connector 5, so the connecting grease grooves 14 are provided on the other side of the second connector 5.
[0045] In this embodiment, both the stop grease groove 13 and the connecting grease groove 14 are used to store lubricating grease. When the first connecting member 4 rotates relative to the second connecting member 5, the wear between the stop ring 2 and the second connecting member 5 can be reduced, which helps to improve the service life.
[0046] Preferably, the pivot body 1 has a first linkage connecting section 7, a partition section 9, and a second linkage connecting section 8 connected in sequence;
[0047] The outer diameters of both the first connecting segment 7 and the second connecting segment 8 are smaller than the outer diameter of the separating segment 9.
[0048] In this embodiment, the design of the partition 9 can prevent mutual interference between the first connector 4 and the second connector 5.
[0049] Preferably, both sides of the first linkage connecting segment 7 and both sides of the second linkage connecting segment 8 have linkage planes 25.
[0050] Correspondingly, the first connecting member 4 is provided with a first sleeve hole 18 that is adapted to the first linkage connecting section 7, and the stop ring 2 is provided with a stop sleeve hole 19 that is adapted to the second linkage connecting section 8.
[0051] To achieve relative rotation between the second connecting member 5 and the second linkage connecting section 8, the second connecting member 5 is provided with a second sleeve hole 20, the inner diameter of which is larger than that of the second linkage connecting section 8. The second sleeve hole 20 is circular.
[0052] For structural optimization, the first connector 4 is sleeved on the first linkage connecting section 7;
[0053] The second connecting piece 5 is sleeved on the second linkage connecting section 8, and the stop ring 2 is located between the partition section 9 and the second connecting piece 5;
[0054] The end of the second linkage section 8 is threaded with an adjusting nut 10. The end of the second linkage section 8 is provided with a threaded section, and the adjusting nut 10 can be threadedly connected to the aforementioned threaded section.
[0055] An interference component is also provided between the second connecting member 5 and the adjusting nut 10 on the pivot body 1.
[0056] In this embodiment, the interference component provides an interference force to the pivot 1. Thus, when the first connecting member 4 rotates relative to the second connecting member 5, the interference component can be used to position the rotation angle, preventing accidental rotation and wobbling. The magnitude of the interference force can be adjusted by adjusting the distance between the adjusting nut 10 and the second connecting member 5.
[0057] Preferably, the interference assembly includes two friction plates 11 and a plurality of interference plates 12 located between the two friction plates 11.
[0058] In this embodiment, the friction plate 11 should be linked to the second linkage connecting section 8. When relative rotation occurs between the first connecting member 4 and the second connecting member 5, the friction plate 11 can reduce the mutual influence between the interference component and the second connecting member 5. The interference plate 12 can be an elastic pad.
[0059] Preferably, both sides of the friction plate 11 are provided with a plurality of concave friction grease grooves 15. The friction grease grooves 15 are used to store lubricating grease. When relative rotation occurs between the first connecting member 4 and the second connecting member 5, they can reduce the wear between the interference component and the second connecting member 5, and help to improve the service life.
[0060] 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.
