Description

Technical Field

[0001] The present application relates to the technical field of damping shafts, and in particular to a damping shaft structure. Background Art

[0002] The principle of the damping hinge is actually to generate friction through the squeezing between the gaskets. The magnitude of the friction depends on the number of gaskets installed and the tightness of the nuts. For example, when we flip open the laptop screen, a certain amount of force is required, and this force does not need to be very large. When we stop flipping, the screen will not shake up and down or left and right and fall off, but rely on the friction on the hinge to keep the laptop screen in the position we want.

[0003] Chinese patent authorization announcement number: CN221942966U discloses a damping shaft for laptop computers. In this solution, the threaded rod is limited in the through hole by a limit ring and a gear, so there is no phenomenon of losing parts. With the assistance of a chain, when the gear is rotated, another gear is synchronously driven to rotate, so it is very convenient to install it.

[0004] The current damping hinge structure only achieves the purpose of locking through the friction on the hinge, so that the laptop screen maintains a stable position. However, as the laptop screen is used more and more, the gaskets between the damping hinges will wear out, causing the gap between the gaskets to increase, thereby reducing the friction and weakening the damping effect. When the laptop screen is opened to a certain angle, it may not be able to stay stably in that position.

[0005] Therefore, it is necessary to provide a damping shaft structure to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

When the display screen is in a stationary state, additional stability is provided for the fixed shaft, preventing the display screen from loosening due to reduced friction, so that the display screen can maintain the required position and angle.

[0008] The technical solution adopted by the present application to solve its technical problems is: a damping shaft structure, including: a fixed connection part, a movable connection part and a pair of limit assemblies, a pair of connecting sleeves are installed on the fixed connection part, a connecting block is installed on one side of the movable connection part, a fixed shaft is installed on the connecting block, the fixed shaft passes through a pair of connecting sleeves and is rotatably connected to the pair of connecting sleeves, a plurality of limiting holes distributed in an annular shape are opened at both ends of the fixed shaft, a pair of the limiting assemblies are respectively detachably installed on one side of a pair of connecting sleeves, the limiting assembly includes a limiting block and a plurality of springs, a plurality of limiting columns are installed on one side of the limiting block through a plurality of springs, and the limiting columns are adapted to the limiting holes.

[0010] Furthermore, an internal thread is engraved on the inner wall of the connecting hole, and an external thread matching the internal thread is provided on the outer wall of the limiting block.

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] like Figure 1-4 As shown, the present application provides a damping shaft structure, including: a fixed connection part 1, a movable connection part 2 and a pair of limit assemblies 5, a pair of connecting sleeves 3 are installed on the fixed connection part 1, the connecting sleeves 3 and the fixed connection part 1 are integrally formed, a connecting block 4 is installed on one side of the movable connection part 2, the connecting block 4 is fixed to one side of the movable connection part 2 by bolts, a fixed shaft 6 is installed on the connecting block 4, the fixed shaft 6 is fixedly connected to the connecting block 4, the fixed shaft 6 passes through the pair of connecting sleeves 3 and is rotatably connected to the pair of connecting sleeves 3, a plurality of limiting holes 10 distributed in an annular shape are opened at both ends of the fixed shaft 6, a pair of limiting assemblies 5 are respectively detachably installed on one side of a pair of connecting sleeves 3, the limiting assembly 5 includes a limiting block 51 and a plurality of springs 54, a plurality of limiting columns 53 are installed on one side of the limiting block 51 through a plurality of springs 54, and the limiting columns 53 are adapted to the limiting holes 10.

[0027] In this embodiment, the solution is used in a laptop computer, mainly for connecting the display screen and the main body of the computer, ensuring that it can withstand both bending moment and torque when rotating or folding;

[0028] Specifically, by connecting the fixed connection part 1 to the main body of the computer and the movable connection part 2 to the display screen of the computer, the friction between the fixed shaft 6 and the two connecting sleeves 3 is used to keep the laptop screen at the desired position.

[0029] Among them, by installing a limiting assembly 5 at the end of the connecting sleeve 3, multiple limiting columns 53 can be stuck in the limiting hole 10 at the end of the fixed shaft 6 under the elastic force of the spring 54, so that the fixed shaft 6 is guaranteed to be in a stable state. When the display screen connected to the movable connecting part 2 rotates, the fixed shaft 6 is synchronously driven to rotate. At this time, the limiting column 53 is blocked and the spring 54 is compressed and disengaged from the limiting hole 10, thereby not affecting the rotation of the fixed shaft 6. Through the above design, when the display screen is in a stationary state, additional stability is provided for the fixed shaft 6 to prevent the display screen from loosening due to reduced friction.

[0030] like Figure 2 As shown, a pair of connecting sleeves 3 are both provided with connecting holes 9 at their ends, and the limiting blocks 51 are adapted to the connecting holes 9 .

[0031] In this embodiment, the provided connecting hole 9 can reserve space for the installation of the limiting block 51 .

[0032] like Figure 2-4 As shown, the inner wall of the connecting hole 9 is engraved with an internal thread, and the outer wall of the limiting block 51 is provided with an external thread that matches the internal thread.

[0033] In this embodiment, the threaded connection method is adopted to facilitate the later disassembly of the limit assembly 5. When the toughness of the spring 54 in the limit assembly 5 decreases after long-term use, the limit assembly 5 can be removed and replaced with the spring 54.

[0034] like Figure 4 As shown, a plurality of mounting holes 52 equidistantly distributed in a circular shape are provided on one side of the limiting block 51 , a plurality of springs 54 are installed in the mounting holes 52 , the end of the limiting column 53 is hemispherical, and the cross section of the limiting hole 10 is hemispherical.

[0035] In this embodiment, the mounting hole 52 is provided to provide space for the spring 54. When the computer display screen is in a stable state, the limit column 53 is stuck in the limit hole 10 by the elastic force of the spring 54. When the display screen rotates, the limit column 53 is forced to move into the mounting hole 52. After the display screen is stable, the limit column 53 is stuck in the limit hole 10 again.

[0036] like Figure 2 As shown, a pair of first gaskets 7 are installed on the outer side wall of the fixed shaft 6, and a second gasket 8 is installed on one end of the pair of connecting sleeves 3. The pair of first gaskets 7 are respectively in contact with the pair of second gaskets 8.

[0037] In this embodiment, the first gasket 7 and the second gasket 8 are arranged to abut against each other. When the display screen connected to the movable connection part 2 rotates, the first gasket 7 and the second gasket 8 rub against each other to generate friction, thereby improving the damping effect.

[0038] Working principle:

[0039] By connecting the fixed connection part 1 to the main part of the computer and the movable connection part 2 to the display screen of the computer, the friction between the fixed shaft 6 and the two connecting sleeves 3 is used to make the notebook screen stay in the position we want to keep. By installing a limiting component 5 at the end of the connecting sleeve 3, multiple limiting columns 53 can be stuck in the limiting hole 10 at the end of the fixed shaft 6 by the elastic force of the spring 54, so that the fixed shaft 6 is guaranteed to be in a stable state. When the display screen connected to the movable connection part 2 rotates, the fixed shaft 6 is synchronously driven to rotate. At this time, the limiting column 53 is blocked and the spring 54 is compressed and disengaged from the limiting hole 10, thereby not affecting the rotation of the fixed shaft 6. Through the above design, when the display screen is in a stationary state, additional stability is provided for the fixed shaft 6 to prevent the display screen from loosening due to reduced friction.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
