Description

Damper hinge with consistent opening speed

technical field

The utility model relates to a damping hinge applied to foldable electronic products, such as notebook computers, mobile phones, translators, digital cameras (DV), etc., especially a damping hinge whose opening speed tends to be consistent.

Background technique

Foldable electronic products, such as notebook computers, mobile phones, translators, digital video cameras (DV), etc., must be connected with a hinge to open and close the upper cover (usually a liquid crystal display screen) and the main body (usually a keyboard or buttons) .

Common hinges usually use a spring or shrapnel to provide support for opening the upper cover. However, under the action of the spring, the opening or closing speed of the folding electronic product will be faster and faster, so that when it is fully opened or closed, an impact force will be generated between the upper cover and the main body of the folding electronic product, thus affecting the folding electronic product. The performance of the electronic product itself will have adverse effects and may also easily cause the electronic product to fall from the hands of the user. In order to reduce the impact force generated when the foldable electronic product is opened or closed, a damper is usually arranged coaxially on the hinge to form a damping hinge. For relevant previous cases, please refer to the previous cases such as Taiwan New Patent Announcement No. M322720 "Hub Device", M339891 "Hub Device" and M335121 "Hub Mechanism".

However, since the damping of a general damper is constant, the known damper (compared to the utility model without first and second speed adjustment elastic structures), referring to the opening speed curve shown in Figure 11, is affected by gravity. There will be acceleration phenomenon, which makes the opening action unstable and prone to shaking, which needs to be improved.

4 and 5, the upper cover 91 is closed on the body 92, and the bump 321 of the cam 32 of the first speed adjustment elastic structure 30 is not in contact with the shrapnel 31, while the sliding end 42 of the second speed adjustment elastic structure 40 It is located on the circular outer edge 114 of the shaft hole seat 112 and can slide, so no reverse resistance will be generated.

Referring to Fig. 6 and Fig. 7, when the upper cover 91 is opened relative to the main body 92, as indicated by the arrow G1, after the rotation exceeds 60 degrees, the first speed adjusts the protrusion 321 of the cam 32 of the elastic structure 30 to press the shrapnel 31 to deform, and the second speed The sliding end 42 of the adjustable elastic structure 40 resists against the horizontal bottom edge 115 of the shaft hole seat 112 , both of which generate reverse resistance to slow down the opening speed of the upper cover 91 .

Referring to Fig. 8 and Fig. 9, when the upper cover 91 continues to open to 120 degrees relative to the main body 92, the maximum opening angle, the deformation of the shrapnel 31 of the first speed adjustment elastic structure 30 and the deformation of the torsion spring of the second speed adjustment elastic structure 40 increase to Maximum, the reverse resistance also increases to the maximum.

Since the opening angle of the upper cover 91 relative to the main body 92 increases, the deformation of the shrapnel 31 and the deformation of the torsion spring of the second speed adjustment elastic structure 40 also increase to increase the reverse resistance, so the opening speed of the upper cover 91 can be made to be consistent, reaching The speed change is shown in Figure 10. Compared with the disadvantage of acceleration due to the influence of gravity on the speed curve of the conventional damping hinge shown in FIG. 11 , the utility model can indeed improve the opening speed of the upper cover 91 .
