Abstract

An electric release fastening device for a thin-profile space has a fingerprint identifier, a micro drive motor, a change gear set, an electric controller, an electric battery, a moveable fastening cassette, a fastening cassette control unit and a locking locator. When the fingerprint identifier reads the correct identification information, the micro drive motor is ordered by the electric controller to drive the change gear set, and then change the position of the fastening cassette control unit. This switches the positioning or release state between the moveable fastening cassette and the locking locator, and controls or electrically releases the product cover. With this configuration, the electric release fastening device can be assembled into thin-profile spaces with improved applicability.

Claims

1. An electric release fastening device for a thin-profile space, which is mounted into a thin-profile space preset in the casing and cover of a product, and used to control and switch the positioning and release mode of the casing and cover;

said electric release fastening device comprising;

a fingerprint identifier mounted into either of the casing or the cover;

the fingerprint identifier is provided with an exposed scanner head;

a micro drive motor mounted into the thin-profile space as a driving source;

the micro drive motor is provided with an output screw;

a change gear set mounted into the thin-profile space;

the change gear set includes a start gear, an end gear and a plurality of change gears defined between the start gear and end gear;

of which the start gear is meshed and driven by the output screw of the micro drive motor, and a driving portion is protruded from one side of the end gear;

an electric controller mounted into the thin-profile space including a circuit board, a processor and an electric control component;

the electric controller is electrically connected with the fingerprint identifier and the micro drive motor, enabling it to control the micro drive motor according to the sensing signal of the fingerprint identifier;

an electric battery;

mounted into the thin-profile space and electrically connected with the electric controller, thus providing electric power to the fingerprint identifier, micro drive motor and electric controller;

a moveable fastening cassette, mounted onto one side of the casing (or cover) in a moveable state;

the moveable fastening cassette includes at least one moveable fastening portion and a release control portion;

the moveable fastening portion is protruded towards the cover;

a fastening cassette control unit;

mounted between the end gear of the change gear set and the moveable fastening cassette in a moveable state;

the fastening cassette control unit includes a driven end, a positioning portion and a resetter;

the driven end can be driven by the driving portion of the end gear, while the positioning portion is mated with the release control portion of the moveable fastening cassette to switch the positioning and displacement state of the moveable fastening cassette;

the resetter enables automatic resetting of the fastening cassette control unit;

at least one locking locator mounted at one side of the cover (or casing);

the locking locator enables locking of the moveable fastening portion of the moveable fastening cassette so to as locate the closing state of the cover and the casing.

2. The structure defined in claim 1, wherein the moveable fastening cassette is configured into a curved plate defining a first and a second plate;

a flanged shaft is set pivotally at both sides of the corner of the curved plate, so that the moveable fastening cassette is in a swinging state;

then, the moveable fastening portion is protruded from the end of the first plate, and the release control portion is set at one side of the second plate in a semi-circular groove pattern;

the driven end of the fastening cassette control unit is configured into a hooked pattern, the driving portion of the end gear is configured into a bulging pattern, and the positioning portion of the fastening cassette control unit is configured into an expanded cylindrical pattern that is mated with the release control portion of a semi-circular groove pattern;

the resetter of the fastening cassette control unit is made of a helical spring.

3. The structure defined in claim 1, wherein a power-off sensing switch is arranged in the thin-profile space correspondingly to the driven end of the fastening cassette control unit;

the power-off sensing switch is electrically connected with the electric controller;

when the driven end shifts to the preset location, it touches the power-off sensing switch to generate a power-off signal, enabling stopping of the micro drive motor.

4. The structure defined in claim 1, wherein the casing is provided with a cover jacking member at exterior of the moveable fastening cassette;

the cover jacking member includes a moveable top plate and an elastic supporting member, of which the moveable top plate can be elastically protruded to push the cover via the elastic supporting member.

5. The structure defined in claim 1, wherein a buzzer is mounted into the thin-profile space, and electrically connected with the electric controller, allowing to send out alarming buzz under setting states.

6. The structure defined in claim 1, wherein the locking locator is prefabricated onto the cover or casing;

or alternatively, the locking locator made of metal material is buried into the plastic cover or casing.
