[0001] The utility model relates to the technical field of notebook computers, in particular to a notebook computer shaft with a buffer structure. Background Art

[0002] The laptop hinge is used to rotate the keyboard and display screen and is an indispensable accessory. Laptops are small and easy to carry personal computers, and their market share is gradually increasing. They are likely to replace desktop computers. Due to the portability of laptops, the frequency of use of laptops is much higher than that of desktop computers, which leads to higher wear and tear on laptop components than desktop computers. Therefore, it is also necessary to optimize the structure of laptops.

[0003] For example, a notebook computer hinge is disclosed in a Chinese utility model patent with announcement number CN218235818U. Although the above-mentioned prior art meets the principle of thinness, portability and good appearance of current notebook computers, frequent opening and closing of the notebook computer will cause wear of the notebook computer hinge, making the hinge that originally could get stuck when opening and closing become smooth and not stuck. As a result, when the user closes the notebook computer, the screen will directly hit the computer body when it rotates to a certain angle. Although the impact force is not large, the vibration caused by the long-term impact will loosen the parts inside the computer body, and the long-term impact and vibration will also cause certain damage to the computer screen. Therefore, it is necessary to design a notebook computer hinge that can buffer and prevent the screen from hitting the computer body directly when the notebook computer screen is closed. Utility Model Content

[0004] In order to solve the technical problem that after the rotation shaft of the notebook computer is worn, closing the notebook computer will cause the display screen to directly hit the computer body, the utility model provides a notebook computer rotation shaft with a buffer structure.

[0010] Through the above technical solution, when the display screen is closed, the torsion spring will provide a certain supporting force to the display screen, thereby reducing the closing speed of the display screen.

[0011] As a further improvement of the above solution, sliding bars are fixedly installed on both sides of the display screen, one side of the two sliding bars is provided with a sliding groove running through the two sliding bars, and one end of the two torsion springs passes through the adjacent sliding grooves and is fixedly installed with a limit block.

[0012] Through the above technical solution, the position of the torsion spring can be adjusted, thereby adjusting the supporting strength of the torsion spring.

[0013] As a further improvement of the above scheme, the adjustment assembly includes an adjustment ring slidably mounted on the rotating shaft and a threaded column arranged on one side of the adjustment ring, one end of the threaded column is threaded through the adjustment ring and fits with the surface of the rotating shaft, and the other end of the threaded column is fixedly mounted with a rotating block.

[0014] Through the above technical solution, the adjusting ring squeezes the torsion spring, which will change the supporting strength of the torsion spring.

[0015] As a further improvement of the above scheme, the closing assembly includes an air bag fixedly installed inside the buffer groove, two push plates arranged inside the air bag and a plurality of push springs fixedly installed between the two push plates, and a plurality of small air holes for exhaust and intake are opened on one side of the air bag.

[0016] Through the above technical solution, the display screen will squeeze the air bag when it is closed, allowing the gas in the air bag to be discharged from the small pores. The process of exhausting the air bag will act as a buffer force.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a rotating shaft component, a buffer component, an adjustment component and a closing component. Before closing the display screen, the adjustment component is slid, and the buffering strength of the buffer component can be adjusted by squeezing the buffer component by the adjustment component. When the display screen is closed, the buffer component provides a supporting force, thereby reducing the closing speed of the display screen. The final closing of the display screen will contact the closing component, and the closing component will slowly discharge the internal gas, and the closing of the display screen will also be buffered during the discharge process. This arrangement can achieve a combined buffering effect when the display screen is closed, thereby preventing the display screen from hitting the computer body, causing damage to the display screen and vibration of the computer body.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4A laptop computer hinge with a buffer structure in this embodiment includes a computer body 1, a display screen 2 is provided on one side of the computer body 1, a hinge assembly is provided on one side of the display screen 2 to assist the display screen 2 in rotating with the computer body 1, buffer assemblies are provided at both ends of the hinge assembly to provide buffering when the display screen 2 is closed or opened, an adjustment assembly is provided on one side of each buffer assembly to adjust the buffering force of the buffer assembly, and a closing assembly is provided on one side of each adjustment assembly to assist the buffer assembly in closing buffering when the display screen 2 is closed.

[0027] Combination Figure 1 and Figure 2 A rotation groove is provided on one side of the computer body 1, and the shaft assembly includes a shaft 301 installed inside the rotation groove and a rotation sleeve 302 sleeved on the shaft 301 and fixedly installed with the display screen 2. The shaft 301 cooperates with the rotation sleeve 302 to allow the display screen 2 to rotate with the computer body 1.

[0028] Combination Figure 1 , Figure 2 and Figure 4 , buffer grooves 7 are provided on both sides of the computer body 1, and the buffer assembly includes a torsion spring 401 sleeved on the rotating shaft 301, a fixed sleeve 402 fixedly sleeved on one end of the torsion spring 401, and a connecting block 403 fixedly installed on one side of the fixed sleeve 402 and fixedly installed on the inner wall of the adjacent buffer groove 7. Sliding bars 8 are fixedly installed on both sides of the display screen 2, and one side of the two sliding bars 8 is provided with a sliding groove running through themselves. One end of the two torsion springs 401 passes through the adjacent sliding groove and is fixedly installed with a limiting block 9. When the display screen 2 is closed, the torsion spring 401 will provide a certain supporting force for the display screen 2, thereby reducing the closing speed of the display screen 2.

[0029] Combination Figure 2 and Figure 4 The adjustment component includes an adjustment ring 501 slidably mounted on the rotating shaft 301 and a threaded column 502 arranged on one side of the adjustment ring 501. One end of the threaded column 502 is threadedly penetrated through the adjustment ring 501 and fits with the surface of the rotating shaft 301. The other end of the threaded column 502 is fixedly mounted with a rotating block. When the adjustment ring 501 squeezes the torsion spring 401, the supporting strength of the torsion spring 401 will be changed.

[0030] Combination Figure 2 , Figure 3 and Figure 4The closing component includes an air bag 601 fixedly installed inside the buffer groove 7, two push plates 602 arranged inside the air bag 601 and a plurality of push springs 603 fixedly installed between the two push plates 602. A plurality of small air holes for exhaust and intake are provided on one side of the air bag 601. When the display screen 2 is closed, the air bag 601 will be squeezed to allow the gas in the air bag 601 to be discharged from the small air holes. The exhaust process of the air bag 601 will play a buffering force.

[0031] The implementation principle of a laptop computer shaft with a buffer structure in the embodiment of the present application is as follows: the threaded column 502 is rotated to allow the adjustment ring 501 to slide on the shaft 301. The sliding adjustment ring 501 can squeeze the torsion spring 401. After the torsion spring 401 is squeezed, the magnitude of the force provided will change. The tighter the torsion spring 401 is squeezed, the greater the force provided. When the torsion spring 401 is squeezed, one end will slide inside the sliding groove to facilitate squeezing adjustment, and the other end will be fixed to the inner wall of the buffer groove 7. After adjusting the force provided by the torsion spring 401, the threaded column 502 is rotated to fix the adjustment ring 501. In this way, when the display screen 2 is closed, the torsion spring 401 is 01 will first provide a supporting force to reduce the closing speed of the display screen 2. When the display screen 2 is about to be closed, it will contact the air bag 601 and squeeze the air bag 601. The compressed air bag 601 will discharge the internal gas from the small pores. Since the pores are small, the discharge requires a process. This process will have a buffering effect on the closing of the display screen 2. After a part of the gas is discharged, the display screen 2 can be completely closed. After the display screen 2 is opened, the air bag 601 will be opened by the internal push spring 603 and the push plate 602, and the external air will be re-sucked into the air bag 601 to facilitate the next discharge buffer.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
