Abstract
An input device (100) includes a housing (80), a base (40), a shaft (20), a first elastic member (60), and at least one second elastic member (70). The housing has a cavity (800), a first end and an opposite second open end. The first end has a hole (802) communicated with the cavity. The base is pivotably received in the cavity of the housing with part of the base protruding out of the cavity from the hole. The base defines a through hole (406) and includes at least one protrusion (408). The shaft is slidably received in the through hole of the base. The first elastic member provides a force to reset the shaft. The second elastic member connected to the base and the housing for providing a force to reset the base. The present invention also provides an electronic device employing the input device.
Claims18
An input device comprising:
- a housing having a cavity therein, the housing having a first end and an opposite second open end, the first end having a hole defined therein, the hole being in communication with the cavity;
- a base pivotably received in the cavity of the housing with part of the base protruding out of the cavity from the hole of the housing, the base defining a through hole and including at least one protrusion on a base surface which faces the second open end of the cavity;
- a shaft slidably received in the through hole of the base;
- a first elastic member for providing a force to reset the shaft when the shaft being away from an original position;
- and
- at least one second elastic member connected to the base and the housing for providing a force to reset the base when the base being away from an original position.
An electronic device comprising:
- a main body with a key board having a plurality of keys;
- and
- an input device mounted on the main body, the input device covering at least some of the keys, the input device comprising:
- a housing having a cavity therein, the housing having a first end and an opposite second open end, the first end having a hole defined therein, the hole being in communication with the cavity;
- a base pivotably received in the cavity of the housing with part of the base protruding out of the cavity from the hole of the housing, the base defining a through hole and including at least one protrusion on a base surface which faces the second open end of the cavity;
- a shaft slidably received in the through hole of the base;
- a first elastic member for providing a force to reset the shaft when the shaft being away from an original position;
- and
- at least one second elastic member connected to the base and the housing for providing a force to reset the base when the base being away from an original position.
An auxiliary input mechanism for an electronic device, the auxiliary input mechanism comprising:
- a housing having a first housing end and a second housing end, the first housing end having a housing hole defined therethrough;
- a base received in the housing, the base including a base body and a pole portion extending from the base body, the pole portion extending out of the first housing end via the housing hole, and having a cross-section smaller than the housing hole so as to allow the pole portion to pivot in the housing, the base body having at least one protrusion formed on a base surface which faces the second housing end;
- at least one first spring member each having opposite first and second ends, the first end being fixed to the base body, the second end being fixed to the housing.
