Description

Technical Field

[0001] The invention relates to the field of computer accessories, in particular to a computer rotating shaft provided with a linkage gear set. Background Art

[0002] Most laptops are clamshell type. To meet the design considerations of thinness, smallness and light weight, commonly used computers include an upper cover with a display screen and a base consisting of a keyboard. The upper cover and the base are fixed by a shaft. By rotating the shaft, the upper cover can be lifted to an appropriate angle for operation.

[0003] Regarding the currently used computer shafts, the existing computer shafts are disassembled by threaded connection, which requires many turns of twisting, making it inconvenient to disassemble. At the same time, the threaded connection also makes the installation of the computer shaft cumbersome, reduces the efficiency of installation, and is very inconvenient to use;

[0004] In view of the above technical problems, the existing patent announcement number: CN213498954U discloses a computer shaft that is easy to disassemble; by setting a fixed column, a stopper, an opening, an extension block and an end plate, it is only necessary to lift the stopper so that the center of the stopper and the axis of the fixed column are on the same straight line, that is, the stopper can pass through the through hole, and then the end plate is pulled to the left, and the computer shaft body is gradually moved out to complete the disassembly of the computer shaft body. By setting a fixed column, a stopper, an opening, an extension block and an end plate, it is also necessary to lift the stopper, the stopper can pass through the through hole, and the end plate is pushed to the right, and the computer shaft body gradually moves into the through hole and the connecting hole. When moving, the pin is aligned with the slot. After the end plate contacts the left vertical plate, the stopper automatically falls due to its own weight, and the installation is completed, solving the problem of inconvenient disassembly and inconvenient installation;

[0005] Although the above patent can solve the problem that the computer shaft is inconvenient to disassemble and install,

[0006] However, after long-term use, the hinge of the laptop will suffer from wear, fatigue, aging and quality problems, which will reduce the damping effect of the hinge, causing the computer screen that has been positioned at a good angle to become loose, or even unable to support the computer screen that has been fixed at a good angle.

DETAILED DESCRIPTION

[0032] Specific implementation method 1: Please refer to Figure 1-8 The present invention provides a technical solution: a computer shaft with a linkage gear set, including a shaft body 17, the shaft body 17 includes a drum 7 welded and fixed to a column 8, and a first gear 6 is welded and fixed to the left surface of the drum 7, and a second gear 9 is welded and fixed to the right surface of the drum 7, and a first computer seat mounting plate 4 is installed on the left side of the first gear 6, and the first computer seat mounting plate 4 is sleeved on the central shaft 1; a second computer seat mounting plate 10 is installed on the right side of the second gear 9, and a linkage gear assembly 16 is arranged at the bottom of the second computer seat mounting plate 10 and the first computer seat mounting plate 4;

[0033] The linkage gear assembly 16 includes a left limit plate 162 fixedly connected to the first lock gear 163, and a fourth spring 161 is arranged on the left side of the left limit plate 162. At the same time, the first lock gear 163 is fixed to the rotating shaft 160, and the end of the rotating shaft 160 away from the first lock gear 163 is welded and fixed to the square shaft 165.

[0034] Working principle: When in use, the first computer seat mounting plate 4 and the second computer seat mounting plate 10 are fixed to the computer seat of the notebook by screws; the display screen mounting plate 15 is fixed to the computer display screen by screws; when the display screen needs to be flipped open and closed, it is realized by the rotating cylinder 7 movably arranged in the middle of the central axis 1;

[0035] When the unfolded display screen needs to be rotated, it can be realized by movably setting the fixing piece 12 on the central axis 1, so that the unfolded display screen can be displayed in all directions, which is convenient for using the display screen.

[0036] Specific implementation method two: This implementation method is a further limitation of specific implementation method one, the first computer seat mounting plate 4 and the second computer seat mounting plate 10 are symmetrical structures about the rotating drum 7, and the first computer seat mounting plate 4 and the second computer seat mounting plate 10 are both "L"-shaped structures made of metal material, and multiple groups of mounting holes are evenly arranged on the first computer seat mounting plate 4 and the second computer seat mounting plate 10, and the first computer seat mounting plate 4 and the second computer seat mounting plate 10 are fixed to the computer seat of the notebook by screws; threaded structures are arranged on the surfaces of both ends of the central axis 1, and both ends of the central axis 1 are screwed and fixed with side nuts 2, and the first spring 3 and the second spring 5 are installed on both sides of the central axis 1, and the first spring 3 and the second spring 5 are respectively installed on both sides of the first computer seat mounting plate 4.

[0037] like Figure 1-8 As shown: the rotating drum 7 is sleeved on the outside of the central axis 1 and is locked by tightening the side nut 2 to ensure the stability of the rotating drum 7 when it is stationary under force. When the rotating drum 7 becomes loose, the side nut 2 can be tightened, and the side nut 2 moves inward. By reducing the distance between the side nut 2 and the first gear 6, the compression of the first spring 3 and the second spring 5 is achieved, and the friction between the rotating drum 7 and the central axis 1 is increased, thereby finally achieving the purpose of limiting the rotating drum 7, but the rotating drum 7 will not be locked. The rotating drum 7 can still rotate on the central axis 1, and after the opening and closing angle of the display screen is locked, it will not shake; the installation method of the second computer seat mounting plate 10 is consistent with the installation method of the above-mentioned first computer seat mounting plate 4, which will not be repeated here.

[0038] Specific implementation method three: This implementation method is a further limitation of specific implementation method one. The axial cross-section of the central shaft 1, the first gear 6, the rotating drum 7 and the second gear 9 is a concentric circle structure, and the size of the rotating drum 7 is adapted to that of the central shaft 1, and the rotating drum 7 is movably sleeved on the outside of the central shaft 1, and the rotating drum 7 and the column 8 are combined together to form a "T"-shaped structure.

[0039] Specific implementation method four: This implementation method is a further limitation of specific implementation method one. A supporting plate 11 is welded and fixed in the middle of the column 8, and a fixing plate 12 is installed on the surface of the supporting plate 11. At the same time, the fixing plate 12 is sleeved on the outer side of the column 8, and the end of the fixing plate 12 is fixed to the display screen mounting plate 15; the display screen mounting plate 15 is a "U"-shaped structure made of metal material, and a plurality of mounting holes are evenly arranged on the display screen mounting plate 15. At the same time, the display screen mounting plate 15 is fixed to the computer display screen by screws.

[0040] like Figure 2-8 As shown: a fixed support plate 11 is welded to the middle of the column 8. After the upper nut 14 on the top of the column 8 is tightened, the distance between the upper nut 14 and the support plate 11 can be reduced, and the third spring 13 is compressed to increase the friction force on the fixing plate 12, so as to limit the display screen fixed to the display screen mounting plate 15, thereby ensuring the stability of the display screen after rotation, and preventing it from loosening without external force interference.

[0041] Specific embodiment 5: This embodiment is a further limitation of specific embodiment 1. The top of the column 8 is screwed and fixed with an upper nut 14, and a third spring 13 is set at the bottom of the upper nut 14. At the same time, the third spring 13 is sleeved on the outside of the column 8, and the third spring 13 is set between the fixing plate 12 and the upper nut 14; the second lock gear 164 is set at the end of the first lock gear 163, and the first lock gear 163 and the second lock gear 164 have the same diameter. At the same time, the upper part of the first lock gear 163 is meshed and connected with the bottom of the first gear 6, and the upper part of the second lock gear 164 is meshed and connected with the bottom of the second gear 9, and the diameters of the first gear 6 and the second gear 9 are the same. The left outer part of the rotating shaft 160 is sleeved with a fourth spring 161, and the fourth spring 161 is clamped between the first computer seat mounting plate 4 and the left limit plate 162.

[0042] like Figure 3-8 As shown: In order to further improve the stability of the display screen after opening, the hinge of the display screen will not become unusable as the use time and frequency increase;

[0043] At this time, the bottoms of the first gear 6 and the second gear 9 at both ends of the rotating drum 7 are locked by the first locking gear 163 and the second locking gear 164 respectively. Even when the computer hinge of the notebook cannot support the display screen, the design of the linkage gear assembly 16 can ensure the stability of the display screen when used at any angle.

[0044] Specific embodiment six: This embodiment is a further limitation of specific embodiment one, one end of the square shaft 165 is fixed to the second lock gear 164, and the other end of the square shaft 165 is fixed to the force-bearing shaft 168, and at the same time, one end of the force-bearing shaft 168 is fixedly connected to the button 169, and the end of the force-bearing shaft 168 away from the button 169 is fixed to the right limit plate 167, the fifth spring 166 is installed on the left side of the force-bearing shaft 168, and the fifth spring 166 is clamped between the right limit plate 167 and the second computer base mounting plate 10, and the button 169 is movably inserted in the accommodating hole opened on the side wall of the computer base; the cross-section of the square shaft 165 is a square structure, and the cross-section of the force-bearing shaft 168 is a circular structure.

[0045] like Figure 2-8 As shown: the linkage gear assembly 16 is designed in such a way that when the display screen shaft is damaged and cannot be supported, the button 169 is pressed, and the button 169 moves to the left through the square shaft 165 and the rotating shaft 160, so that the square shaft 165 arranged in a square is disengaged from the square hole opened on the surface wall of the second computer seat mounting plate 10, and the circular force-bearing shaft 168 is inserted into the square hole. When the display screen is rotated, there is no interference between the first gear 6, the first locking gear 163, the second gear 9, and the second locking gear 164, so that the display angle of the display screen can be fixed;

[0046] like Figure 3-8 As shown: when the display angle of the display screen is adjusted, the button 169 is released, and the compressed fourth spring 161 rebounds, so that the square shaft 165 is reinserted into the square hole opened on the surface wall of the second computer seat mounting plate 10, and the display angle of the display screen is locked. Even when the rotating shaft body 17 fails and cannot be used, the display angle of the display screen can be fixed.

[0047] The display screen and the keyboard base of the notebook computer are movably connected through the hinge body 17. Figure 8 The button 169 shown in the figure is used to adjust the angle of the display screen and lock the operation. Figure 8 It is the mirror image of the computer after installing the shaft body 17 and the linkage gear assembly 16.
