Description

A hub for improved positioning

【Technical field】

The utility model relates to a hinge device with improved positioning function, in particular to a hinge device arranged between an upper cover and a base of a flip-cover device.

【Background technique】

Flip-top devices (such as notebook computers, mobile phones, etc.) have a relative upper cover and a base, and a hinge is provided between the upper cover and the base so that the upper cover can be opened or closed relative to the base. Nowadays, due to the needs of use, many In addition to enabling the upper cover to be opened or closed relative to the base, the flipping device also needs to enable the upper cover to rotate relative to the base. The hinge device in the prior art has a rotating shaft and a fixed shaft that are pivotally connected to each other. The cover is fixed to each other, the fixed shaft and the base are fixed to each other, and the upper cover is rotated relative to the base by rotating the rotating shaft relative to the fixed shaft. The function is generally to use the relative concave-convex structure to cooperate. When the relative concave structure rotates to fit with the convex structure, a positioning effect is produced. However, the structural design of the hinge in the prior art is such that when the concave structure does not When the convex structure fits together and the rotating shaft rotates relative to the fixed shaft, the concave structure and the convex structure are tightly fitted by the elastic structure, so the user must spend a lot of effort to make the rotating shaft relative to the fixed shaft Rotate, but when the structure of the concave part is turned to fit with the structure of the convex part, the convex part structure will quickly sink into the structure of the concave part due to the action of elastic force, due to the friction force originally produced to resist the tight fit between the concave part structure and the convex part structure , the user exerts a large torsional force, but the instantaneous friction force of the convex structure quickly sinking into the concave structure becomes smaller, and the user has no time to react and still applies a large torsional force, which may cause the upper cover to be subjected to excessive torsional force. The concave-convex part is separated from the fitting state, so the positioning effect cannot be effectively presented. At the same time, the excessive torsional force is also easy to cause the upper cover to shake under force, and the screen on the upper cover is easily damaged.

【Content of utility model】

In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a hinge device with improved positioning function, which is arranged with relative elastic pieces, so that the upper cover suffers less frictional resistance when it rotates relative to the base , and the frictional resistance is greater when the positioning effect is to be produced, so as to improve the positioning effect and prevent the screen from shaking.
