Background

A hinge is a mechanism element widely used in the field of daily life and electronic products. Generally, a hinge device includes a first rotating member and a second rotating member coaxially pivoted to each other, and the rotating members are respectively connected to two parts of an electronic product, such as a notebook computer, such as an upper cover and a base, so that the upper cover can be opened and closed rotationally relative to the base. In order to support the weight of the upper cover and the base and reduce the force required for opening and closing, the hinge device usually further comprises a torsion element to provide the torsion required during the opening and closing process.

When the pivot device is assembled, the two coaxial pivoted bearing frames are respectively connected between the upper cover and a convex part of the base, namely, the connecting position of the upper cover and the base is fixed and cannot be changed along with the lifting angle of the upper cover. For example, after the upper cover of the electronic product is rotated and opened relative to the base through the hinge, the upper cover touches the protrusion of the base to form interference, and the upper cover cannot be opened to a preset maximum opening angle. Therefore, the solution of the workers in the art is to increase the structural distance (gap) between the protruding portion of the base and the top cover, which is undoubtedly the relative state that the display screen is pulled away when in use, and at the same time, the structural distance also causes a visual defect which is not good for the aesthetic property of the electronic product.

As shown in fig. 1 to 5, the hinge device with translation function in the present application includes a base 1, a shaft mechanism 2, and a torsion assembly 3.

The base 1 includes three parallel vertical frames 11 arranged at intervals, and each vertical frame 11 is horizontally provided with a sliding slot 111, and a first accommodating slot 12 and a second accommodating slot 13 are respectively formed at two sides of the middle vertical frame 11, and the second accommodating slot 13 is horizontally provided with a rack 131. As shown in fig. 5, the rack 131 is recessed in a bottom wall of the second receiving groove 13. In another embodiment, the rack 131 is protruded on the bottom wall of the second receiving groove 13.

Furthermore, for convenience, the linking shaft mechanism 2 can be connected and installed in the sliding slot 111 of each vertical frame 11, so that a through slot 112 is vertically arranged on one side of each sliding slot 111 and communicated with the sliding slot 111. Referring to fig. 4 and 5, the sliding groove 111 and the through groove 112 form an inverted L-shaped groove.

In addition, the base 1 is provided with a plurality of first connection holes 14 on the periphery thereof, so that the base can be connected to a base of an electronic product, such as a notebook computer (shown in fig. 10), by using conventional connecting members, such as screws (not shown in the drawings), to pass through the first connection holes 14.

The linking shaft mechanism 2 includes a first shaft 21 and a second shaft 22 passing through the sliding slot 111 of each stand 11. A connecting plate 211 is disposed at one end of the first shaft 21, and a plurality of second connecting holes 212 are formed in the connecting plate 211, so that the connecting plate can be inserted through each of the second connecting holes 212 by using a conventional connecting member, such as a screw (not shown), and can be locked to an upper cover (shown in fig. 10) of the electronic product, such as a notebook computer. The first shaft 21 has a driving gear 213 disposed in the first receiving cavity 12. The second shaft 22 has a first driven gear 221 located in the first receiving cavity 12 and engaged with the driving gear 213, and a second driven gear 222 located in the second receiving cavity 13 and engaged with the rack 131.

The torque assembly 3 is disposed outside a stand 11 opposite to the connecting piece 211, and is used for the first shaft rod 21 and the second shaft rod 22 to pass through and be linked, so as to provide a friction torque to each of the first and

second shaft rods

21, 22. As shown in fig. 1 and 2, the torque assembly 3 includes at least one torque clamping piece 31, and two ends of the at least one torque clamping piece 31 are respectively provided with a first C-shaped clamp 311 for the first shaft 21 to penetrate and clamp, and a second C-shaped clamp 312 for the second shaft 22 to penetrate and clamp.

The number of the at least one torsion clip 31 is formed in a stacked multi-piece manner, so that the number of the torsion clips 31 of the torsion assembly 3 can adjust the torsion to a predetermined value for the first spindle 21 and the second spindle 22. In other words, the torsion assembly 3 can flexibly adjust the number of the torsion clips 31 according to the weight of the portion of the electronic product connected to the hinge or the actual requirement of the opening and closing.

The first shaft rod 21 and the second shaft rod 22 are respectively provided with a torsion auxiliary adjusting unit 4 outside the torsion assembly 3, each torsion auxiliary adjusting unit 4 comprises at least one friction pad 41 for the first shaft rod 21 and the second shaft rod 22 to respectively penetrate and link, an elastic element 42 for the first shaft rod 21 and the second shaft rod 22 to respectively penetrate, and a pressing element 43, such as an anti-falling nut, for the first shaft rod 21 and the second shaft rod 22 to respectively lock, thereby facilitating the slight adjustment of the torsion values of the

shaft rods

21 and 22.

Referring to fig. 1 and 2, the at least one friction pad 41 is two pieces, one piece of which is adjacent to the torsion assembly 3, the other piece of which is adjacent to the pressing member 43, and the elastic member 42 is disposed between the two friction pads. Furthermore, the elastic element 42 is selected from a plurality of disc-shaped elastic pieces, but not limited thereto, and in other embodiments, the elastic element 42 may be selected from a spring or a plurality of wave-shaped elastic pieces. Therefore, the first shaft 21 and the second shaft 22 are respectively affected by the elastic force of each elastic element 42 during the rotation, so as to form the axial torque variation and generate the stagnation and positioning effect.

As shown in fig. 3, a perspective view of the assembled hinge device is shown. As seen from fig. 4, the driving gear 213 located in the first receiving cavity 12 is engaged with the first driven gear 221. As seen from fig. 5, the rack 131 and the second driven gear 222 located in the second receiving groove 13.

Referring to fig. 3 and 10, the base 1 of the hinge device passes through the first connecting holes 14 by using the existing connecting members, such as screws, so as to lock the base 1 to an electronic product 5, such as a base 51 of a notebook computer. The first shaft 21 is also inserted through the second connecting holes 212 of the connecting piece 211 by using the existing connecting elements, such as screws, so as to lock the first shaft 21 to an upper cover 52 of the electronic product 5. Wherein the base 51 and the cover 52 of the electronic product 5 are in a closed state, that is, the angle of the first shaft 21 relative to the base 1 is 0 degree.

Referring to fig. 6, 7 and 11, to use the electronic product 5, a user only needs to open the top cover 52 forward (counterclockwise) to a first angle, for example, 20 degrees, at this time, the driving gear 213 of the first shaft 21 rotates counterclockwise and drives the first driven gear 221, the second shaft 22 and the second driven gear 222 to rotate clockwise together, so that the second driven gear 222 moves backward (relative to the visual direction of the user) along the rack 131 of the base 1 and drives the first shaft 21 and the second shaft 22 to synchronously translate forward in the sliding slots 111.

Referring to fig. 8, 9 and 12, the user continues to lift the upper cover 52 forward by hand to a second angle, for example, 120 degrees, during which the driving gear 213 of the first shaft 21, the first driven gear 221 and the second driven gear 222 of the second shaft 22 move according to the aforementioned movement manner, so that the first shaft 21 and the second shaft 22 continue to synchronously translate forward in the sliding slots 111.

If the user does not intend to use the electronic product 5, the upper cover 52 only needs to be closed backwards (clockwise), so that the first shaft rod 21 and the second shaft rod 22 move backwards together in the sliding slots 111 and synchronously translate backwards until the upper cover 52 of the electronic product 5 and the base 51 are closed.

Therefore, through the implementation of the present invention, the effect obtained by the present invention is that when the upper cover of the electronic product is lifted, the linking shaft mechanism including the first shaft rod and the second shaft rod in the hinge device can form a translational motion in the base, so as to overcome the interference phenomenon in the prior art, and reduce the structural distance between the upper cover and the base, which is a good structure of the same kind of articles.

It is apparent to those skilled in the art that various changes and modifications can be made in the invention without departing from the scope of the invention.
