JP7020207B2 - Locking structure for electronic devices - Google Patents

Description

The present invention relates to a locking structure of an electronic device, particularly an electronic device, an internal storage device thereof, and a plurality of electronic devices when stacked, each of which is intended to prevent theft.

Conventionally, a wire lock (for example, Kensington lock) is known as a device for preventing the theft of an electronic device such as a personal computer or an external hard disk. This wire lock locks the electronic device with the lock part and attaches the wire part to the desk to prevent theft.
In recent years, many electronic devices have rectangular holes formed in a part of the housing so that they can be locked with this wire lock. A lock portion formed in a T-shaped piece is fitted into this hole and rotated by 90 ° to be locked so that the lock portion and the hole are orthogonal to each other.

In recent years, even if the main body of an electronic device is not stolen, the SSD (Solid State Drive), which is installed inside the electronic device and stores important information, or the outside connected to the main body of the electronic device via USB. If a storage device such as an attached HDD (Hard Disk Drive) is stolen, serious damage such as information leakage will occur. Therefore, the main body of the electronic device and the internal storage device, or the storage device connected to the main body of the electronic device There is a demand for a structure that prevents both from being stolen (for example, Patent Document 1).

Patent Document 1 is an anti-theft device that locks a long hole-shaped security slot formed in a housing of a device with a T-shaped shaft of a wire lock, and is attached to an opening of the housing so as to be openable and closable. It has a shutter for covering an object that is detachably inserted in the portion, and a bar member that is movably attached between the security slot and the shutter in the housing, and the bar member is housed from the security slot. It discloses an anti-theft device characterized by being driven by a T-shaped shaft rotated 90 degrees after insertion into the body and locking the movement of the shutter in the opening direction. As a result, the bar member driven by the T-shaped shaft of the wire lock locks the shutter for taking out the storage device, and the bar member cannot be released unless the wire lock is removed. Therefore, by locking one wire lock, both the housing (the main body of the electronic device) and the storage device can be locked.

However, in Patent Document 1, since the bar member is driven and locked by the rotation of the T-shaped shaft, it is necessary to provide the positional relationship between the two at a very close position. For example, if it is the side surface of an electronic device, it must be provided on the side surface, and the degree of freedom in design is limited. In addition, locking is limited to a single electronic device, and there is a problem that it cannot be used with a storage device such as an HDD externally attached to the electronic device.
