Description

Fixing mechanism

The present invention relates to a securing mechanism, and more particularly to a securing mechanism for securing a peripheral component to an electronic device.

A fixing mechanism is usually provided on an electronic device such as a notebook or a mobile phone for detachably fixing the peripheral components of the electronic device to the electronic device.

A locking mechanism for fixing to a peripheral component of an electronic device. The locking mechanism includes a casing, a pressing member, a slider and an elastic member. The casing has a receiving portion for receiving the peripheral component. The pressing member is movably disposed in the casing and adjacent to the receiving portion. The elastic member is sleeved on the pressing member and abuts against the casing. The slider has a first end that contacts the pressing member and a second end that contacts the peripheral component. A positioning groove is defined in a sidewall of the receiving portion. The peripheral component is provided with a positioning protrusion that cooperates with the positioning groove. When the pressing member is pushed toward the first end of the slider, the second end of the slider pushes the peripheral component to disengage the positioning protrusion from the positioning groove, and the peripheral component is topped from the receiving portion Thereby, the peripheral component is conveniently taken out.

However, it is difficult for the fixing mechanism to firmly fix the peripheral component to the receiving portion of the casing. For example, when the electronic device is subjected to a strong impact, the positioning protrusion is easily separated from the positioning groove, thereby making the peripheral component easy to be driven. The shell is removed from the housing.

In view of the above, it is necessary to provide a fixing mechanism in which the peripheral components of the fixed electronic device are relatively strong.
