Description

Shaft structure

【Technical field】

The invention relates to a rotating shaft structure, in particular to a rotating shaft structure of an electronic product.

【Background technique】

At present, notebook computers, PDAs, palmtop computers, LCD computers, LCD monitors, LCD TVs, and mobile phones often use shaft structures to achieve the purpose of rotating the display device.

Subdivided according to its structure, it can be roughly divided into a straight shaft, a spring type shaft, and a bracket type shaft. Many models have complex structures, and the shafts of each model have various shortcomings, which are not suitable for general use. This has obvious obstacles in factory assembly and design.

The rotating shaft structure generally has a shaft rotating upper seat connected with the display part and a shaft rotating lower seat connected with the main machine part, especially for the rotating shaft structure with bearings, the shaft rotating upper seat is in direct contact with the bearing, and the friction force is relatively large. When rotating in the rotating shaft structure, the movable space is small.

In view of this, it is necessary to develop a rotating shaft structure to solve the above problems.

【Content of invention】

Therefore, the object of the present invention is to provide a rotating shaft structure to solve the problems of high frictional force and small moving space during rotation.

In order to achieve the above object, the present invention provides a rotating shaft structure, the rotating shaft structure is connected to the display part and the host part of the electronic product, and a rotating rod is provided at the bottom of the display part, and the rotating shaft structure includes:

The shaft screw upper seat has a protruding sleeve at its lower end, and the hollow part of the sleeve penetrates the shaft screw upper seat to form an upper seat hole;

The shrapnel is fixed on the lower end of the shaft screw seat and is close to or attached to the outer wall of the sleeve;

a bearing sleeved on the outer wall of the sleeve;

The lower seat for rotating the shaft has a lower seat hole, and the lower seat for rotating the shaft is sheathed outside the sleeve and the bearing through the lower seat hole.

Optionally, the electronic product is a notebook computer.

Optionally, the shrapnel is a C-shaped shrapnel.

Optionally, a hinge shaft is also fixed on the shaft screwed on the seat.

Optionally, a first annular spacer is sheathed on the sleeve, and the first annular spacer is arranged between the shrapnel and the bearing.

Optionally, there is a guide rail under the first annular spacer.

Optionally, a hollow fitting groove is fixed under the shaft unscrewing seat, and a plurality of second annular spacers are fixed in the fitting groove.

Optionally, there are two second annular gaskets.

Optionally, a third annular gasket is further provided below the plurality of second annular gaskets.

Compared with the prior art, with the rotating shaft structure of the present invention, since the shrapnel is set up between the bearing and the shaft screw-on seat, the frictional force is smaller, and the rotation rod in the rotating shaft structure There is more space for activities.

【Detailed ways】

Please refer to Fig. 1-Fig. 4 together, Fig. 1 is shown as the structure diagram of the first angle of a preferred embodiment of the rotating shaft structure of the present invention, and Fig. 2 is shown as a comparison of the rotating shaft structure of the present invention A schematic structural view of the second angle of the preferred embodiment, FIG. 3 is a cross-sectional view of FIG. 1 , and FIG. 4 is a schematic diagram of an exploded structure of FIG. 3 .

In order to achieve the above purpose, the present invention provides a rotating shaft structure, which is used to connect the display part and the host part of an electronic product (such as a notebook computer), and the bottom of the display part is provided with a rotating rod. In this embodiment, the Shaft structure includes:

The shaft screw upper seat 10 has a protruding sleeve 11 at its lower end, and the hollow part of the sleeve 11 penetrates the shaft screw upper seat 10 to form an upper seat hole 12;

Elastic piece 20, which is fixed on the lower end of the shaft screw upper seat 10 and is close to or attached to the outer wall of the sleeve 11. The elastic piece 20 is, for example, a C-shaped elastic piece here, and of course it can also be an elastic piece with other asymmetric structures;

The bearing 30 is sleeved on the outer wall of the sleeve 11;

The shaft rotation lower seat 40 has a lower seat hole 41 , and the shaft rotation lower seat 10 is sheathed outside the sleeve 11 and the bearing 30 through the lower seat hole 41 .

When in use, the rotating rod is inserted into the upper seat hole 12 of the shaft rotating upper seat 10 until the shaft rotating lower seat 40 is connected in series, and the rotating rod is rotated, the generated torque pushes the bearing 30 to operate, thereby achieving the desired Describe the purpose of display rotation.

To sum up, using the rotating shaft structure of the present invention, since the elastic sheet 20 is set up between the bearing 30 and the shaft screw-on seat 10, the frictional force is smaller, and the rotating rod is in the rotating shaft structure. more space for activities.

In this embodiment, the hinge shaft 50 can also be fixed on the shaft screw-on seat 10, so that the shaft structure can achieve the purpose of the hinge between the display part and the host part; A first annular gasket 60 can also be sleeved, and the first annular gasket 60 is arranged between the elastic piece 20 and the bearing 30, thereby reducing friction and increasing the friction of the rotating rod. activity space; there may also be a guide rail 61 under the first annular spacer 60 to facilitate the position-limiting operation of the bearing 30; a hollow fitting groove 70 is fixed under the shaft screw-down seat 40, and the fitting Several (here, for example, two) second annular gaskets 80 can be fixed in the matching groove 70, so that the number of shrapnels can be adjusted to adapt to different torsion forces and the length of the rotating rod; A third annular gasket 90 is also provided below the annular gasket 80 to seal the bottom.
