Detailed Description

Referring to fig. 1 to 4, the embodiment of the hinge mechanism 100 of the present invention includes a shaft frame member 1 and a hinge member 2. It should be noted that the shaft frame member 1 can be used to connect to a first body (not shown) of an electronic device, and the shaft member 2 can be used to connect to a second body (not shown) or a base (not shown) of the electronic device, but not limited to the above connection manner.

The shaft frame member 1 includes a fixing section 11 extending along a first direction D1 and a second direction D2 perpendicular to each other and being plate-shaped, and a shaft frame section 12 extending from the fixing section 11 toward the first direction D1 and surrounding and defining a shaft hole 121, where the shaft hole 121 extends along the second direction D2, it should be noted that the structure of the fixing section 11 can be adjusted as required, and is not limited by the present embodiment. The shaft bracket section 12 has a body 122 formed by extending from the fixing section 11 around the shaft hole 121 along a first rotation direction R1, and a tongue piece 123 formed by extending from the body 122 around the shaft hole 121 along a second rotation direction R2 opposite to the first rotation direction R1, wherein the ends of the body 122 and the tongue piece 123 are free ends.

In this embodiment, the body 122 is formed with an opening 122a extending around the shaft hole 121, and the tongue piece 123 is formed extending from an inner edge of the opening 122a of the body 122. In detail, the body 122 has a connection end portion 122b connected to the fixed segment 11, two wrapping portions 122c respectively formed extending from the connection end portion 122b in the first rotation direction R1, and a free end portion 122d connected to ends of the two wrapping portions 122 c. The connecting end portion 122b, the two wrapping portions 122c and the free end portion 122d together define the opening 122 a. The tongue piece 123 is formed extending from the free end 122d of the body 122 along the second rotation direction R2. It should be noted that in other variation embodiments, the structures of the body 122 and the tongue pieces 123 of the shaft bracket section 12 may be adjusted according to requirements, for example, the body 122 may only have one wrapping portion 122c, so that the body 122 and the tongue pieces 123 of the shaft bracket section 12 form a U-shaped structure (not shown), and the number of the bodies 122 and the number of the tongue pieces 123 may be two or more in other embodiments, which should not be limited by this embodiment.

The rotating shaft member 2 is generally cylindrical, the rotating shaft member 2 rotatably penetrates through the shaft hole 121 of the shaft frame member 1 and is surrounded by the body 122 and the tongue piece 123 of the shaft frame section 12 of the shaft frame member 1, and the rotating shaft member 2 is tightly fitted with the body 122 and the tongue piece 123.

Referring to fig. 1, 2, 5 and 6, when the rotating shaft 2 rotates relative to the shaft frame 1 along the extending direction of the body 122 of the shaft frame section 12 (i.e. along the first rotation direction R1), the friction force generated will increase the binding force of the body 122 to the rotating shaft 2, and further increase the anti-rotation torque provided by the body 122 to the rotating shaft 2; the friction generated when the shaft member 2 rotates with respect to the shaft member 1 against the extending direction of the body 122 of the shaft bracket section 12 (i.e. rotates in the second rotating direction R2) will reduce the binding force of the body 122 to the shaft member 2, and thus reduce the torsion force against rotation provided by the body 122 to the shaft member 2. However, when the shaft member 2 rotates relative to the shaft frame member 1 along the extending direction of the tongue pieces 123 of the shaft frame section 12 (i.e. along the second rotation direction R2), the friction force generated will increase the binding force of the tongue pieces 123 on the shaft member 2, and thus the torsion force against rotation provided by the tongue pieces 123 on the shaft member 2 will increase; the friction force generated when the shaft member 2 rotates with respect to the shaft member 1 against the extending direction of the tongue pieces 123 of the shaft frame section 12 (i.e. rotates in the first rotating direction R1) will reduce the binding force of the tongue pieces 123 to the shaft member 2, and thus reduce the torsion force against rotation provided by the tongue pieces 123 to the shaft member 2. Therefore, by the body 122 and the tongue piece 123 of the pedestal section 12 extending around the shaft hole 121 in different rotation directions (the first rotation direction R1 and the second rotation direction R2) and ending at free ends, the aforementioned variations of the anti-rotation torque provided by the body 122 and the tongue piece 123 can be mutually offset, so as to reduce the difference of the anti-rotation torque generated when the rotating shaft member 2 rotates relative to the pedestal member 1 in different rotation directions.

In addition, the shaft holder 1 and the rotating shaft 2 are made of metal in this embodiment, but the shaft holder 1 and the rotating shaft 2 may be made of other materials such as plastic in other embodiments, and the present embodiment is not limited thereto.

Referring to fig. 1, 2, 4 and 7, in addition, in the present embodiment, the width W1 of each of the two wrapping portions 122c of the body 122 is the same as the width W2 of the tongue 123, as shown in fig. 4, so as to ensure that the structural strength of the body 122 and the tongue 123 can be balanced. In addition, in the embodiment, when the rotating shaft member 2 is not yet inserted into the shaft frame member 1, the curvature of the tongue piece 123 is larger than that of the body 122, as shown in fig. 7. Therefore, the tight fit degree between the tongue piece 123 and the rotating shaft member 2 is greater than that between the body 122 and the rotating shaft member 2, so as to reduce the difference in the magnitude of the anti-rotation torque provided by the tongue piece 123 and the body 122, respectively, and further reduce the difference in the magnitude of the anti-rotation torque generated when the rotating shaft member 2 rotates relative to the shaft frame member 1 in different rotating directions. However, the ratio of the width W1 of each wrapping portion 122c of the body 122 to the width W2 of the tongue 123 and the curvature of the body 122 and the tongue 123 can be adjusted according to the requirement, and should not be limited by the present embodiment. In addition, although the tongue pieces 123 are substantially rectangular strips in the present embodiment, the tongue pieces 123 may have a strip structure such as a regular trapezoid, an inverse trapezoid, a water drop type, an S-curve type, and the like, and are not limited in the present embodiment.

In detail, since the tongue pieces 123 are formed on the body 122, the structure of the pedestal section 12 is easy to machine, so that the pedestal member 1 is easy to manufacture and the manufacturing cost is reduced. For example, for the structure of the shaft bracket section 12 of the present embodiment, when manufacturing the shaft bracket member 1, a U-shaped notch (defined by the body 122 and the tongue piece 123 before forming) may be formed on a metal plate (not shown), the body 122 and the tongue piece 123 of the shaft bracket section 12 are formed in a one-step manner by a round-wrapping forming method, and finally, the curvature of the tongue piece 123 is adjusted according to the torque requirement, so as to complete the manufacturing process of the shaft bracket member 1.

To sum up, the utility model discloses a different direction of rotation in edge of pedestal section 12 winds shaft hole 121 extends to form and end for the free end body 122 with tongue piece 123 reduces pivot piece 2 with different direction of rotation for produced anti rotation torque size's difference when pedestal piece 1 rotates. In addition, since the tongue pieces 123 are formed on the body 122, the structure of the shaft bracket section 12 is convenient to machine and form, so that the shaft bracket member 1 is easy to manufacture and the manufacturing cost is reduced.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
