The second end of the lever is provided with a sleeve, and the sleeve is sleeved on the shaft. The sleeve only needs to provide a connecting function and does not need to provide an energy storage function, can be less limited by the diameter, and can also uniformly compress the friction element. Alternatively, the second end of the lever does not have to be sleeved outside the shaft, but only needs to be capable of pressing the friction element, and the diameter limitation caused by the disc spring can be overcome.
The friction member includes a first friction member and a second friction member which are disposed at an interval and pressed by the second end of the lever, the first friction member is connected with the link plate to rotate together with the link plate with respect to the shaft, the second friction member is connected with the second connection member to rotate together with respect to the shaft, and the second connection member and the rotating plate are rotatable with respect to each other. Thus, it has a better connecting function and facilitates the thinning design and application to portable electronic terminals, especially biaxial portable electronic terminals.
Furthermore, the two sides of the elastic mechanism are provided with the levers, and the two ends of the elastic mechanism respectively act on the levers on the two sides, so that the space can be fully utilized to improve the torque output efficiency and the balance. The levers on both sides respectively press a group of friction elements.
Furthermore, the elastic mechanism is a plate spring formed by connecting a plurality of wire springs in parallel. It is possible to contribute to thinning the design. Alternatively, other springs or a spring mechanism combining a spring and a mechanical connection structure may be used.
The utility model also provides a portable electronic terminal, it sets up any one of the above-mentioned and provides big moment of torsion hinge.
The portable electronic terminal may be a dual-axis portable mobile terminal that is provided with two sets of high-torque hinges, the second parts of the two sets of hinges being the same part or fixedly connected together and being in the middle of the dual-axis portable electronic terminal.
Owing to adopt the technical scheme of the utility model, the utility model discloses can compress tightly the friction disc through the lever, can realize big moment of torsion output with less diameter, thickness, can accomplish 1.2mm or even thinner with the thickness of hinge, and simple structure, the moment of torsion size is adjusted easily, is applicable to various portable electronic terminal that have rotating-structure.
