Abstract

Locking mechanisms and separable, repairable (e.g., electronic) devices having locking mechanisms are described herein. In one example, a locking mechanism includes a chassis having a base, a first side wall extending from a surface of the base, and a second side wall extending from the surface of the base. A cavity is provided in a volume formed by the first side wall, the second side wall, and the surface of the base, wherein the cavity is configured to receive a mating component of the device. The locking mechanism also includes a cantilevered plate having a first end and a second, opposite end, wherein the cantilevered plate is attached to the first side wall of the chassis at or adjacent to the first end, and wherein the second end of the cantilevered plate is positioned with the cavity.

First claim

What is claimed is:

1. An electronic device with a locking mechanism, the electronic device comprising;
a chassis having a first outer substrate and a second outer substrate, a first side wall extending from a surface of a base of the first outer substrate near a periphery of the electronic device, and a second side wall extending from the surface of the first outer substrate parallel to the first side wall;
a mating component of the electronic device extending from a surface of a base of the second outer substrate near the periphery of the electronic device;
a cavity provided in a volume formed by the first side wall, the second side wall, and the surface of the first outer substrate near the periphery of the electronic device, wherein the cavity is configured to receive the mating component of the electronic device, at least a portion of the mating component received within the cavity of the electronic device;
a resilient cantilevered plate having a first end and a second, opposite end, wherein the cantilevered plate is attached to the first side wall of the chassis at or adjacent to the first end, and wherein the second end of the cantilevered plate is positioned within the cavity such to lockably engage the mating component therein and such that the first outer substrate and the second outer substrate are matingly engaged to form an enclosed volume; and
internal electrical components contained within the first outer substrate and the second outer substrate in the enclosed volume,
wherein the cantilevered plate is configured to bend at or adjacent to the second end, therein moving between a locked position and an unlocked position, wherein the mating component of the electronic device is securable in the locked position and removable in the unlocked position,
wherein the cantilevered plate comprises a magnetic composition, and
wherein the cantilevered plate is configured to bend via placement of a permanent magnet adjacent to an external surface of the chassis based on a magnetic attraction between the cantilevered plate and the permanent magnet.

2. The electronic device of claim 1 , wherein the cantilevered plate is positioned at an acute angle greater than 0 degrees and less than 90 degrees as measured between a plane formed by the surface of the base of the chassis and a plane formed by the cantilevered plate.

3. An electronic device comprising:
a chassis having a first outer substrate and a second outer substrate, a first side wall extending from a surface of a base of the first outer substrate near a periphery of the electronic device, and a second side wall extending from the surface of the first outer substrate parallel to the first side wall;
a cavity provided in a volume formed by the first side wall, the second side wall, and the surface of the first outer substrate near the periphery of the electronic device;
a mating component of the electronic device extending from a surface of a base of the second outer substrate near the periphery of the electronic device, at least a portion of the mating component received within the cavity of the electronic device such that the first outer substrate and the second outer substrate are matingly engaged to form an enclosed volume;
internal electrical components contained within the first outer substrate and the second outer substrate in the enclosed volume; and
a resilient cantilevered plate having a first end and a second, opposite end, wherein the cantilevered plate is attached to the first side wall of the chassis at or adjacent to the first end, wherein the second end of the cantilevered plate is positioned within the cavity such to lockably engage the mating component therein, and wherein the cantilevered plate is configured to bend at or adjacent to the second end, therein moving between a locked position and an unlocked position,
wherein the cantilevered plate comprises a magnetic composition, and
wherein the cantilevered plate is configured to bend via placement of a permanent magnet adjacent to an external surface of the chassis based on a magnetic attraction between the cantilevered plate and the permanent magnet.

4. The electronic device of claim 3 , wherein the mating component comprises a notch in a surface of the mating component, wherein the notch is configured to receive a portion of the second end of the cantilevered plate and secure the mating component in the locked position.

5. The electronic device of claim 3 , wherein the substrate comprises a display module or an input device.

6. The electronic device of claim 3 , wherein the substrate is an external surface of the electronic device.

7. An electronic device with a locking mechanism, the electronic device comprising:
a chassis having a first outer substrate and a second outer substrate, a first side wall extending from a surface of a base of the first outer substrate near a periphery of the electronic device, and a second side wall extending from the surface of the first outer substrate parallel to the first side wall;
a cavity provided in a volume formed by the first side wall, the second side wall, and the surface of the first outer substrate near the periphery of the electronic device;
a mating component comprising a resilient cantilevered plate having a first end attached to a surface of a base of the second outer substrate near the periphery of the electronic device and a second, opposite end positionable within the cavity;
a retaining device positioned on the first or second side wall, wherein the retaining device is configured to receive a portion of the mating component within the cavity and secure the mating component in a locked position such to lockably engage the mating component therein and such that the first outer substrate and the second outer substrate are matingly engaged to form an enclosed volume; and
internal electrical components contained within the first outer substrate and the second outer substrate in the enclosed volume;
wherein the mating component is configured to bend at or adjacent to the second end, therein moving the locking mechanism between the locked position and an unlocked position, wherein the second outer substrate and the mating component are removable from the first outer substrate in the unlocked position,
where the cantilevered plate comprises a magnetic composition, and
wherein the cantilevered plate is configured to bend via placement of a permanent magnet adjacent to an external surface of the chassis based on a magnetic attraction between the cantilevered plate and the permanent magnet.

8. The locking mechanism of claim 7 , wherein the retaining device is a notch positioned within a surface of the first or second side wall, or a latch extending from the surface of the first or second side wall.
