Detailed Description

Reference is made to the accompanying drawings. The hinge capable of improving the heat dissipation effect of the embodiment is a hinge of a notebook computer. The hinge comprises a shaft 3, an upper casing connecting piece 1 and a lower casing connecting piece 2, the hinge is further provided with a rotary supporting foot 4, the rotary supporting foot 4 comprises a first connecting end 41 positioned on the upper casing 100, a second connecting end 42 positioned on the lower casing 200 and a supporting part 43 positioned between the two connecting ends, the first connecting end and the 41 connecting rod are rotationally connected, the second connecting end 42 and the sliding frame 6 are rotationally connected, and the supporting part 43 of the rotary supporting foot 4 is positioned below the shaft 3. When the upper housing link 1 is rotated in the closing direction, the supporting portion 43 moves upward, and when the upper housing link 1 is rotated in the opening direction, the supporting portion 43 moves downward.

The upper casing connecting piece 1 and the shaft 3 can be fixedly connected to synchronously rotate together, the lower casing connecting piece 2 is rotatably connected with the shaft 3, the upper casing 100 and the lower casing 200 of the notebook computer are respectively fixedly connected with the upper casing connecting piece 1 and the lower casing connecting piece 2, a through hole 21 for supporting the cushion foot 4 to vertically rotate and move is arranged at the bottom of the lower casing 200, wherein the upper casing 100 is provided with a screen, and the lower casing 200 is provided with a host computer and a keyboard. In the drawings, reference numeral 300 is a hinge of the present utility model.

The shaft 3 is connected with the fixed seat 5, the sliding frame 6 is in sliding connection with the fixed seat 5, and the fixed seat 5 is positioned on the lower casing and is fixed with the lower casing through screws.

The sliding frame 6 is provided with a guide hole 60 which is connected with the fixed seat 5 in a sliding way, and two ends of the sliding frame 6 are provided with shaft-shaped bulges 61 which are connected with the second connecting end 42 in a rotating way.

The rotary support foot pad 4 is an L-shaped component.

The first connection end 41 is coaxially connected with the upper casing connection member 1 and the upper casing 100, and reference numeral 7 is a connection shaft.

When the upper casing connecting piece 1 (upper casing) rotates towards the opening direction, the rotary supporting foot 4 is driven to rotate in the same direction, the supporting part 43 at the bottom moves downwards, and the sliding frame 6 synchronously displaces to compensate in the horizontal direction. When the upper casing connecting piece 1 (upper casing) rotates towards the closing direction, the rotary supporting foot 4 is driven to rotate in the same direction, the supporting part 43 at the bottom moves upwards, and the sliding frame 6 synchronously and reversely displaces to compensate in the horizontal direction. The rotary support pad 4 rotates upwards through the through hole 21 to recover the normal state. It can be seen that the height of the foot pad can be increased by extending the length of the second connection end 42 to the supporting portion 43, without being limited by the thickness of the lower case 200.

The torsion mechanism is arranged in the hinge, and the function of stopping rotation at any time and positioning the current rotation angle at any time is provided, so that the conventional torsion structure can be adopted. In the utility model, the torsion mechanism also plays a role in improving the supporting strength of the stand bar. As shown in the figure, in this embodiment, the torsion mechanism employs an elastic member 81 fitted over the shaft, a friction structure 82 fitted over the shaft, and a cam structure 83.
