Hub structure and electronic device using the same

This creation relates to a hub structure, and in particular to a hub structure suitable for use in an electronic device.

A generally foldable electronic device, such as a flip-type mobile phone or a notebook computer, is mainly connected between two bodies (such as a keyboard and a screen) through a hinge structure, so that the two bodies can be rotated relative to each other to expand on each other. Or cover.

Conventional hub structures typically incorporate a stop member to enable stop positioning when the two bodies are relatively open to an angle. However, the current stoppers are generally formed by pressing a stop projection on a plate member to stop the hinge of the hinge structure. However, as the electronic device is lighter and thinner, the thickness of the plate member is also continuously reduced, resulting in limitation of the thickness of the stopper projection and a significant reduction in the stop area and strength.

The pivot structure provided in the present case includes a substrate, a sleeve and a rotating shaft. The surface of the substrate includes a stop region. The sleeve is attached to the side of the substrate. The rotating shaft is rotatably pivoted on the sleeve, and the rotating shaft comprises a shaft and a limiting block protruding from the outer circumference of the shaft. Wherein, when the rotating shaft is rotated by a predetermined angle with respect to the sleeve, the limiting block of the rotating shaft abuts against the stopping area of the substrate surface.

The present invention also provides an electronic device including a first body, a second body, and the above-described hinge structure. The substrate of the pivot structure is connected to the first body, and the rotating shaft of the hinge structure is connected to the second body.

Therefore, when the rotating shaft of the pivot structure of the present embodiment is rotated by a predetermined angle with respect to the sleeve, the limiting block of the rotating shaft directly abuts against the surface of the substrate, and a larger stop area and stop strength can be obtained. . In addition, the pivot structure does not require additional plates for the stop, which simplifies the process and saves costs.

1 is a perspective view of an embodiment of an authoring electronic device. As shown in FIG. 1 , the electronic device 1 includes a first body 11 , a second body 15 , and a hinge structure 20 .

In some embodiments, the electronic device 1 can be a folding electronic device, such as a flip-type mobile phone, a notebook computer, a folding digital camera or an office transaction machine, and the like. As shown in FIG. 1 , the electronic device 1 of the present embodiment is a notebook computer. Here, the first body 11 of the electronic device 1 is a computer body, the second body 15 is a display screen, and the electronic device 1 has two hubs. The structure 20 and the two pivot structures 20 are respectively assembled between the first body 11 and the second body 15 and symmetrically disposed, so that the second body 15 can be opened or closed with respect to the first body 11.

2 is a perspective view of an embodiment of the creative hinge structure, FIG. 3 is an exploded perspective view of an embodiment of the creative hinge structure, and FIG. 4 is a plan view showing an embodiment of the creative hinge structure. In some embodiments, the hinge structure 20 can be a single-shaft, two-axis or one-line isometric hinge. As shown in FIGS. 2 and 3, the hinge structure 20 of the present embodiment includes a substrate 21, a sleeve 25, and a rotating shaft 30. The sleeve 25 has a cylindrical shape and is connected to one of the side edges 22 of the substrate 21. In an embodiment, the sleeve 25 and the substrate 21 can be integrally formed. For example, one side of the sheet metal member may be rounded to integrally form the substrate 21 and the hollow sleeve 25. The rotating shaft 30 is pivoted in the sleeve 25 to be rotatable relative to the sleeve 25 and the base plate 21.

In an embodiment, the substrate 21 and the rotating shaft 30 of the pivot structure 20 can be respectively assembled to the first body 11 and the second body 15. For example, as shown in FIG. 1 and FIG. 2, the substrate 21 of the hinge structure 20 can be fixed to the first body 11 (ie, the computer body). For example, the substrate 21 can be provided with a locking hole 215 for locking. The manner is fixed in the first body 11, and the shaft 31 of the hinge structure 20 is connected to the side of the second body 15 (ie, the display screen) adjacent to the first body 11. For example, the rotating shaft 30 can be embedded in the shaft member 151 of the second body 15, so that the second body 15 can synchronously drive the rotating shaft 30 relative to the sleeve 25 during the opening or closing of the first body 11. Rotating with the substrate 21.

As shown in FIG. 2 and FIG. 3, the rotating shaft 30 of the present embodiment includes a shaft 31 and a limiting block 32 protruding from the outer circumference of the shaft 31. The shaft 31 is a round rod type matching the shape of the sleeve 25. The limiting block 32 and the shaft 31 can be integrally formed. For example, the metal bar can be processed by cutting or milling to integrally form the shaft 31 and the limiting block 32. In addition, as shown in FIG. 3 and FIG. 4, in the present embodiment, the sleeve 25 is connected to a partial edge of the side edge 22 of the substrate 21. The shaft 31 is inserted through one end of the sleeve 25, and the limiting block 32 is abutted. At the end of the sleeve 25. Thereby, when the shaft 31 rotates relative to the sleeve 25, the limiting block 32 will act synchronously to approach or away from the substrate 21. In one embodiment, the thickness of the stop block 32 is equal to or less than the thickness of the sleeve 25 to avoid increasing the thickness of the entire hinge structure 20.

As shown in FIG. 2 and FIG. 3, the limiting block 32 of the rotating shaft 30 of the embodiment is a fan-shaped limiting block, but is not limited thereto. In some implementations, the stop block 32 of the shaft 30 can also be a block of other shapes (eg, circular, square, or irregular). In addition, in some embodiments, the limiting block 32 of the rotating shaft 30 can also be assembled (eg, locked or bonded) to the outer circumference of the shaft 31 rather than being limited to an integrally formed structure.

In one embodiment, the surface of the substrate 21 is reserved for a stop region 211 of the stop stop block 32, in other words, the stop region 211 is a partial region of the surface of the substrate 21. For example, as shown in FIG. 2 to FIG. 4, the substrate 21 of the embodiment includes an upper surface 212 and a lower surface 213. The stop region 211 is located on the lower surface 213 and adjacent to the side 22 of the substrate 21. Corresponding to the limit block 32 of the rotating shaft 30. In one embodiment, the side edge 22 of the substrate 21 includes a first partial edge 221 and a second partial edge 222. The sleeve 25 is coupled to the first partial edge 221, and the limiting block 32 abuts against one end of the sleeve 25 and is adjacent to The second partial edge 222, the stop zone 211 is adjacent to the second partial edge 222 to correspond to the stop block 32 of the rotating shaft 30. Thereby, when the rotating shaft 30 rotates relative to the sleeve 25, the limiting block 32 of the rotating shaft 30 can correspondingly abut against the stopping area 211 of the surface of the substrate 21.

As shown in FIG. 3, in an embodiment, the stop area 211 can be a recessed area, for example, a recessed area can be formed on the surface of the substrate 21 by milling, grinding or stamping, and the stop area 211 can be prevented from contacting the rotating shaft 30. The shaft 31 interferes with rotation. In some implementations, the stop region 211 can also be a partial surface of the substrate 21 rather than being limited to a recessed configuration.

FIG. 5 and FIG. 6 are respectively a schematic diagram of a cover and an opening of an embodiment of the electronic device. As shown in FIG. 5, when the second body 15 is covered by the first body 11, the limiting block 32 of the rotating shaft 30 is away from the substrate 21. As shown in FIG. 6, when the second body 15 is lifted relative to the first body 11 (where the second body 15 is pivoted in a counterclockwise direction), the rotating shaft 30 can be synchronously rotated with its axis counterclockwise. The limiting block 32 is gradually brought closer to the substrate 21.

When the second body 15 is swiveled by a predetermined angle with respect to the first body 11 (the preset angle may be 100 degrees, 110 degrees, 120 degrees or 130 degrees, depending on actual needs of the electronic device 1), the limiting block 32 That is, the stopper body 211 abuts against the surface of the substrate 21, so that the second body 15 is positioned by the stopper. Therefore, the present embodiment can directly abut the surface of the substrate 21 through the limiting block 32, and can greatly increase the stop area to increase the stop strength, avoid deformation or breakage of the limiting block 32 or the substrate 21, and prevent the first The second body 15 passes over the edge of the substrate 21 due to the force, resulting in a problem of exceeding the preset angle and losing the stop function. In addition, the pivot structure 20 does not need to additionally add a plate for the stop, which simplifies the process and saves cost.

As shown in FIG. 6 , in some embodiments, the central angle θ1 of the sector limiting block 32 of the rotating shaft 30 may be the same as the preset angle θ2 of the second body 15 swinging, for example, the central angle θ1 and the preset angle θ2 may be When the second body 15 is rotated relative to the first body 11 by a predetermined angle θ2, the limiting block 32 can abut against the stop region 211 of the surface of the substrate 21.

In addition, in an embodiment, the limiting block 32 of the rotating shaft 30 can increase the length in the axial direction as required, and can further increase the stopping area and increase the stopping strength without increasing the shaft diameter of the rotating shaft 30. As shown in FIG. 7 , with respect to the embodiment of FIG. 3 , the axial length of the limiting block 32 of the rotating shaft 30 is longer. For example, the axial length of the limiting block 32 of the embodiment of FIG. 3 is 1 mm. The axial length of the stop block 32 of the embodiment of Figure 7 is increased to 3 mm. The length of the substrate 21 is further lengthened, and the stop region 211 corresponding to the length of the limiting block 32 can be reserved to increase the stop strength of the limiting block 32 against the area of the substrate 21. In some embodiments, the pivot structure 20 can also reduce the axial length of the sleeve 25, so that the substrate 21 can reserve a larger range of the stop regions 211 so that the axial length of the limiting block 32 of the rotating shaft 30 is It can be further increased to save cost and avoid the space for compressing other components without increasing the volume of the hinge structure 20.

In addition, when the shaft diameter of the rotating shaft 30 is reduced (for example, in response to the thinned electronic device 1), the axial length of the limiting block 32 and the range of the stopping portion 211 can be increased to increase the stop area. The pivot structure 20 is capable of achieving a predetermined stop strength. That is, the smaller the shaft diameter of the rotating shaft 30, the longer the axial length of the limiting block 32 and the larger the range of the stopper region 211. Therefore, the pivot structure 20 of the present embodiment can adjust the axial length of the limiting block 32 to generate different stopping strengths according to different usage requirements.

As shown in FIG. 3, in an embodiment, the inner diameter of the sleeve 25 can be slightly smaller than the shaft diameter of the shaft 31, so that the shaft 31 can be assembled to the sleeve 25 to generate appropriate torque between each other. When the second body 15 is prevented from being separated from the first body 11, the limiting block 32 directly hits the surface of the substrate 21 to cause the hinge structure 20 to be damaged.

As shown in FIG. 3 to FIG. 6 , the second partial edge 222 of the side 22 of the substrate 21 of the embodiment further includes an extension member 23 , and the extension member 23 is disposed along the outer circumference of the shaft 31 . The extension member 23 and the substrate 21 may be integrally formed, and the extension member 23 covers a partial area of the outer circumference of the shaft 31 to provide a limiting function for the shaft 31. In an embodiment, a distance can be maintained between the extension member 23 and the shaft 31 so that the shaft 31 does not interfere with the extension member 23 when rotated relative to the sleeve 25.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art, and some modifications and refinements that do not depart from the spirit of the present invention should be included in the creation. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
