Description
Technical Field
[0001] The utility model belongs to the technical field of rotating shafts, and particularly relates to a rotating shaft of a notebook computer. Background Art
[0002] The notebook computer realizes the opening and closing function between the main body and the display screen through the rotation of the connecting shaft, and this opening and closing angle depends on the design of the connecting shaft. Currently, the common connecting shaft structure for realizing 360° opening and closing is a double-axis core rotating shaft. Generally, the existing notebook computer rotating shafts adopt two rotating shafts, each provided with a spiral curve guiding groove, and a sliding component is arranged between the two rotating shafts. The sliding component moves between the guiding grooves, thereby realizing the function switching between the two rotating shafts. The two shafts of the existing double-axis rotating shaft rotate simultaneously, that is, similar to a double-joint structure, which will cause the rotating shaft body to be unable to provide rotational support, resulting in a jerky feeling when the display screen of the notebook computer is opened.

[0022] Embodiment 1:
[0023] As Figures 1 - 8 shown, a laptop computer hinge provided by the present invention includes a housing 1. A fixing component 2 is fixedly installed on the housing 1.

Connecting plates 22 are fixedly installed on both the first shaft 3 and the second shaft 4.
[0024] Through the above technical solution, the fixing component 2 of the utility model is movably connected to the first shaft 3 and the second shaft 4 through two shaft holes respectively. The fixing component 2 includes a limiting component 5 and a damping component 6. A limiting wheel 7 is movably installed between the limiting component 5 and the damping component 6. Both the first shaft 3 and the second shaft 4 are fixedly installed with a notch gasket 8 and a limiting gasket 9. The notch gasket 8 is provided with an arc-shaped notch. By cooperating the limiting wheel 7 with the notch gasket 8, the first shaft 3 or the second shaft 4 is locked. Specifically: in the initial state, the notch gasket 8 on the second shaft 4 is fixed by the limiting wheel 7, that is, the limiting wheel 7 is embedded in the arc-shaped notch on the notch gasket 8 of the second shaft 4, so that the notch gasket 8 of the second shaft 4 is fixed, and the second shaft 4 is locked. At this time, the first shaft 3 rotates. When the first shaft 3 rotates to the limiting angle, that is, the first shaft 3 rotates to the limit position and is fixed by the limiting component 5. At this time, the arc-shaped notch on the notch gasket 8 of the first shaft 3 is aligned with the arc-shaped notch on the notch gasket 8 of the second shaft 4, and the first shaft 3 at this time is fixed by the limiting component 5. When the rotating shaft is rotated again, the second shaft 4 rotates and pushes the limiting wheel 7 to be embedded in the arc-shaped notch on the notch gasket 8 of the first shaft 3, so that the first shaft 3 is fixed by the limiting wheel 7. At this time, the second shaft 4 completes the opening and closing process of the rotating shaft. By cooperating the limiting wheel 7 with the notch gasket 8, the first shaft 3 and the second shaft 4 rotate alternately, so that each shaft has a stable rotation support during rotation, preventing the display screen from having a jerky feeling when the laptop is opened and improving the user experience.
[0025] Embodiment 2:
[0026] Such as Figures 1 - 8As shown in the figure, the utility model includes a housing. The main function of the housing 1 is to protect the structure of the internal rotating shaft from the external environment, while maintaining the stability and durability of the rotating shaft. The material of the housing 1 is stainless steel, which has high strength and wear resistance to ensure that it can effectively resist external impacts and wear during long-term use. A fixing component 2 is fixedly installed on the inner wall of the housing 1. This fixing component 2 is a key part of the rotating shaft. The fixing component 2, the first shaft 3 and the second shaft 4 are combined to form the main structure of the rotating shaft. The fixing component 2 is provided with two shaft holes, which are respectively used for movably installing the first shaft 3 and the second shaft 4. The first shaft 3 and the second shaft 4 are the main supporting components of the rotating shaft and form the basic framework of the rotating shaft together with the fixing component 2. The fixing component 2 includes a limiting component 5 and a damping component 6. The main function of the limiting component 5 is to limit the rotation angles of the first shaft 3 and the second shaft 4 to prevent the first shaft 3 and the second shaft 4 from exceeding the predetermined angle range during the opening and closing process. The core component of the limiting component 5 is the limiting wheel 7. The limiting wheel 7 is used to dynamically lock the first shaft 3 or the second shaft 4. The function of the damping component 6 is to provide a damping effect for the rotation of the rotating shaft. The second assembly plate 13 in the damping component 6 and the first assembly plate 11 of the limiting group are symmetric structures and are used to install the limiting wheel 7. During the operation of the rotating shaft, a notch gasket 8 and a limiting gasket 9 are respectively fixed on the first shaft 3 and the second shaft 4. The notch gasket 8 is provided with arc-shaped notches. The cooperation between these notches and the limiting wheel 7 enables the first shaft 3 and the second shaft 4 to achieve the function of alternately locking during rotation. Specifically, when the rotating shaft is in the initial state, the notch gasket 8 on the second shaft 4 is fixed by the limiting wheel 7, that is, the limiting wheel 7 is embedded in the arc-shaped notch on the notch gasket 8 of the second shaft 4, so that the second shaft 4 is locked. In this case, the first shaft 3 can rotate freely. When the first shaft 3 rotates to a certain angle, that is, reaches the preset limiting angle, at this time, the arc-shaped notches on the notch gasket 8 of the first shaft 3 are aligned with the arc-shaped notches on the notch gasket 8 of the second shaft 4. At this time, the limiting wheel 7 can move between the two arc-shaped notches. At this time, the first shaft 3 is fixed by the limiting component 5. When the rotating shaft is rotated continuously, since the limiting wheel 7 can move, the second shaft 4 rotates and pushes the limiting wheel 7 to be embedded in the notch gasket 8 of the first shaft 3, so that the position of the first shaft 3 is locked. In this way, the second shaft 4 can remain freely movable during rotation, while the first shaft 3 is fixed. The limiting component 5 includes a limiting plate 10 and a first assembly plate 11. The design of the limiting plate 10 needs to have high strength and wear resistance to cope with the wear during long-term use. The cooperation between the limiting plate 10 and the limiting wheel 7 determines the rotation locking state of the first shaft 3 and the second shaft 4. The utility model realizes the stability and smoothness of the rotation of the rotating shaft by setting the notch gasket 8 and the limiting gasket 9 on the shaft and combining with the precise control of the limiting wheel 7. This design not only improves the opening and closing operation experience of the notebook computer, but also effectively solves the problem of jerks generated during the rotation of the traditional double-axis rotating shaft.
[0027] Both the first assembly plate 11 and the second assembly plate 13 of the present utility model are provided with oval holes 14. The main function of these oval holes 14 is to provide a translation space for the connecting shaft of the limit wheel 7. The two ends of the connecting shaft of the limit wheel 7 are respectively installed in the oval holes 14 of the first assembly plate 11 and the second assembly plate 13. Through this structure, the limit wheel 7 can perform a translation movement within the range of the oval holes 14. The geometric shape of the oval holes 14 allows the limit wheel 7 to translate during the rotation of the rotating shaft. The notch gasket 8 is a key component for locking the position of the shaft in the rotating shaft structure. It is provided with an arc-shaped notch, and in cooperation with the limit wheel 7, it can lock the first shaft 3 or the second shaft 4. Specifically, during the rotation of the limit wheel 7, through the translation movement of the oval holes 14, it can be embedded into the arc-shaped notch on the notch gasket 8 at an appropriate position, thereby locking (fixing) the first shaft 3 or the second shaft 4.
[0028] The limit plate 10 of the present utility model is provided with a limit block 15, and the damping plate 12 is provided with a recessed structure 16. The limit plate 10 and the damping plate 12 play an important role in the functional performance and operating experience of the rotating shaft. The main function of the limit block 15 is to cooperate with the limit gasket 9 to limit the rotation range of the first shaft 3 and the second shaft 4. The function of the recessed structure 16 of the damping plate 12 is to cooperate with the damping gasket 17 to generate a damping effect. The design of the recessed structure 16 enables the damping gasket 17 to contact the damping plate 12 and generate a damping force.
[0029] Both the first shaft 3 and the second shaft 4 of the present utility model are fixedly installed with damping gaskets 17, spring washers 18 and nuts 19. The coordinated action of these components improves the damping effect and operating experience of the rotating shaft. There are multiple spring washers 18, and the number is 4 - 10. The multiple spring washers 18 can significantly increase the amplitude of elasticity, thereby enhancing the overall damping feel of the rotating shaft. The setting of the multiple spring washers 18 not only provides a wider elastic range but also enhances the resilience of the rotating shaft, enabling each opening and closing operation to maintain a consistent damping feeling. During the operation of the rotating shaft, the first shaft 3 or the second shaft 4 presses the spring washer 18 against the damping gasket 17 through the nut 19. This pressing effect enables the damping gasket 17 to closely cooperate with the recessed structure 16 on the damping plate 12 to generate a damping effect.
[0030] The damping plate 12 of the present utility model is fixedly installed with a stud 20. The stud 20 is fixedly connected to the housing 1 through a bolt 21. The connection between the stud 20 installed on the damping plate 12 and the housing 1 improves the connection stability between the fixing component 2 and the housing 1, thereby enhancing the stability and durability of the entire rotating shaft structure.
[0031] Both the first shaft 3 and the second shaft 4 of the present utility model are fixedly installed with connecting plates 22. The connecting plates 22 play a role of physically connecting the rotating shafts with the computer body or the display screen in the rotating shaft system, ensuring that the computer body and the display screen can work together during the opening and closing process. Through this fixed connection, the connecting plates 22 transfer the rotating ability of the rotating shafts to each component of the computer, thereby realizing the opening and closing function of the notebook computer screen. The connection mode between the connecting plates 22 and the computer body or the display screen includes being fixed by bolts 21, rivets or other mechanical connection methods. This connection ensures the firmness between the connecting plates 22 and the relevant components, so that the rotating shafts will not have any looseness or displacement due to insecure connection during operation. The connection between the connecting plates 22 and the computer body or the display screen not only needs to meet the strength requirements, but also needs to consider the precise docking during the connection process to ensure the smooth progress of the opening and closing actions of the rotating shafts.
