Pivot structure and electronic device using the same

The present invention relates to a structural component of an electronic device, and more particularly to a pivotal structure of an electronic device.

An electronic device (eg, a notebook computer) typically includes a screen and a host that receives display signals from a system disposed in the host to display a picture. When the electronic device is used, the screen is often easily shaken by external force, so how to suppress the displacement of the screen and control the frequency of the screen shaking has always been one of the key points in the design of the electronic device.

In general, in addition to strengthening the structural design on the system side and the screen side, the traditional manufacturer uses the pivoting structure provided at the joint between the screen and the host to reduce the screen shake by using the torque generated by the conventional manufacturer. However, in order to effectively suppress the vibration or shaking of the screen, the volume of the hinge in the pivotal structure must be increased to provide greater torque, which would be detrimental to the utilization of the internal space of the electronic device. In addition, the system side and the screen end must also be structurally adjusted to be compatible with hinges having different specifications, which is inconvenient. Therefore, a pivotal structure that can effectively suppress sloshing, that is, a height is required.

In view of the above, an object of the present invention is to provide a pivotal structure for reinforcing two bases by increasing the friction between the components of the pivotal structure. Stability between the seats.

The second base includes a first shaft, wherein the first shaft passes through the hole and pivots about a center of the hole. The torque unit is coupled to the first rotating shaft and provides a torque to the first rotating shaft. The connecting rod is pivotally disposed on the second base, and includes a protruding post slidably disposed in the sliding slot, wherein the width of the second end portion is narrower than the width of the first end portion, and the protruding post The width is greater than the width of the second end.

In the above preferred embodiment, the chute includes a first segment and a second segment coupled to the first segment. a first segment is located between the first end and a reference point, and a second segment is between the reference point and the second end, wherein the width of the stud is less than or equal to the width of the first segment, and The width of the stud is greater than the width of the second segment. During the pivoting of the second base relative to the first base, in order to gradually increase the friction between the two, the width of the first section of the chute decreases from the first end toward the reference point. And the width of the second section of the chute remains the same from the reference point toward the second end. With the above configuration, the pivoting of the first base around the perforation of the second base drives the stud from the first segment to the second segment, and when the stud is located in the second segment, the The chute is deformed by the compression of the stud.

In the above preferred embodiment, the second base includes a second turn a shaft, the second rotating shaft is adjacent to the first rotating shaft, and the connecting rod is pivotally disposed on the second rotating shaft. The length of the connecting rod is greater than the distance between the second rotating shaft and the first rotating shaft.

In the above preferred embodiment, at least one of the first base and the stud is made of an elastic material, wherein the elastic material comprises aluminum or plastic.

The present invention also provides an electronic device including the above pivotal structure, wherein the electronic device further includes a first module and a second module. The first base of the pivoting structure is disposed on the first module, and the second base of the pivoting structure is disposed on the second module.

The pivoting structure of the present invention increases the friction between the two bases when they are relatively pivoted by a connecting rod disposed between the two bases to enhance the effect of suppressing vibration or shaking.
