Description

Technical Field

[0001] The utility model relates to a hinge with a movable rotating shaft and a notebook computer, in particular to a hinge used in a mobile terminal, wherein the mobile terminal may be a notebook computer or the like. Background Art

[0002] Laptops have an upper and lower housing, with the lower housing housing the main unit and the upper housing housing the screen. The two housings are connected by a hinge. Heat dissipation has always been a challenge for laptops. One solution is to use a separate stand that elevates the lower housing at the base when the laptop is open, increasing airflow and achieving better heat dissipation. However, this results in a cluttered and less cohesive design, making the user experience less enjoyable.

[0003] To address this issue, some hinges have an automatic lift function. When the upper case is opened, the lower case automatically lifts to improve heat dissipation. However, hinges that improve heat dissipation by modifying the upper case's trajectory to allow it to move away from the lower case require a comparative control mechanism and a slotted connection to the shaft on the lower case. This makes it difficult to eliminate axial play with an elastic mechanism, and the structure is relatively complex. Utility Model Content

[0006] The lower housing connecting member is provided with a first connecting groove connected to the main shaft, wherein the first connecting groove is a long groove, so that the shaft can rotate and move in the first connecting groove;

[0007] The lower casing connecting member or a component fixedly connected thereto is provided with a second connecting groove, and the second connecting groove is connected to the eccentric structure, allowing the eccentric structure to move in the second connecting groove. Through the cooperation between the eccentric structure and the second connecting groove, the movement of the shaft along the first connecting groove is controlled when the upper casing connecting member rotates, and the upper casing connecting member is also caused to move accordingly.

[0008] On the basis of adopting the above technical solutions, the present invention may also adopt the following further technical solutions, or use these further technical solutions in combination:

[0009] The upper casing connector is provided with a shaft sleeve connected to the shaft, and the other end of the bottom of the shaft sleeve is provided with the eccentric structure.

[0010] The fixing member is provided with a fixing foot connected to the lower housing connecting member and a second connecting groove setting plate, and the second connecting groove is located on the side where the eccentric structure is located.

[0011] The width of the second connecting groove is narrower than that of the first connecting groove, and the diameter of the eccentric structure is smaller than that of the shaft.

[0012] An axial pressing mechanism is sleeved on the shaft, and the lower casing connecting piece is provided with a first connecting groove setting plate. The axial pressing mechanism presses the first connecting groove setting plate and the upper casing connecting piece.

[0013] An axial pressing mechanism is sleeved on the shaft, and a first connecting groove setting plate is provided on the lower housing connecting piece. The axial pressing mechanism presses the first connecting groove setting plate and the shaft sleeve.

[0014] The shaft is also provided with a friction assembly, which is compressed by the axial clamping mechanism.

[0015] The axial pressing mechanism includes a plurality of elastic components, a locking nut and a gasket, and the elastic component is a disc spring.

[0016] The eccentric structure is an eccentric protrusion or an eccentric shaft.

[0017] The second object of the present invention is to provide a laptop computer using the above-mentioned hinge, which adopts the following technical solutions:

[0018] The notebook computer comprises an upper casing and a lower casing, wherein the lower casing is provided with a mainframe and the upper casing is provided with a screen, and is characterized in that the upper casing and the lower casing are connected by the above-mentioned hinge.

[0019] Due to the technical solution of the present invention, the shaft is located on the side of the rotating connecting frame in the hinge and can move when the rotating connecting frame rotates. When the screen of the laptop is connected to the rotating connecting frame, it can be separated from the main body during the screen opening process, thereby improving the heat dissipation effect of the main body. In addition, the axial elastic pressing mechanism can be used to press the screen to ensure that there is no axial shaking when the screen is opened, thereby improving the quality.
