Abstract
A key preloading structure including a base, a set of switches and a set of keys is provided. The set of switches is arranged on the base. The set of keys has a rotating shaft and two extended elastomers. The rotating shaft is assembled on the base. One end of each extended elastomer is fixedly connected to the rotating shaft, and another end is disposed on the set of switches. Each of the two extended elastomers preloads the set of switches with a gravity less than a triggering force for starting the set of switches.
Claims20
A key preloading structure, comprising:
- a base;
- a set of switches arranged on the base;
- and
- a set of keys having a rotating shaft and two extended elastomers, wherein the rotating shaft is assembled on the base, one end of each extended elastomer is fixedly connected to the rotating shaft, another end of each extended elastomer is disposed on the set of switches, each of the two extended elastomers preloads the set of switches with a gravity less than a triggering force for starting the set of switches.
A key assembly method used in a key preloading structure comprising a base, a set of switches and a set of keys, wherein the set of keys has a rotating shaft and two extended elastomers, and the key assembly method comprises:
- assembling the rotating shaft on the base, and restricting the rotation of the rotating shaft by a detachable component;
- temporarily connecting one end of each extended elastomer to the rotating shaft, and disposing another end of each extended elastomer on the set of switches, wherein each of the two extended elastomers preloads the set of switches with a gravity less than a triggering force for starting the set of switches;
- and
- fixedly connecting one end of each extended elastomer to the rotating shaft, and detaching the detachable component.
