Abstract

A detachable fixing mechanism and a related electronic device can be used to fix an object on a bracket. The detachable fixing mechanism includes a positioning pin and an actuating component. The positioning pin is disposed on the bracket, and includes a supporter whereon an annular sunken slot is formed. The supporter can pierce through an opening on the object. The actuating component includes a constraining slab portion and a contacting slab portion. The constraining slab portion includes a first engaging structure engaged with the annular sunken slot to constrain a movement between the positioning pin and the actuating component. The contacting slab portion flexibly bends from the constraining slab portion. The contacting slab portion includes a second engaging structure connected to the first engaging structure and slidably disposed on the supporter. The contacting slab portion can move relative to the supporter to press the object on the bracket.

First claim

What is claimed is:

1. A detachable fixing mechanism capable of fixing an object on a bracket, the detachable fixing mechanism comprising:
a positioning pin comprising a supporter whereon an annular sunken slot is formed, the supporter being adapted to pierce through an opening on the object; and
an actuating component detachably disposed on the positioning pin, the actuating component comprising:
a constraining slab portion comprising a first engaging structure, the first engaging structure being adapted to engage with the annular sunken slot to constrain a relative movement between the positioning pin and the actuating component; and
a contacting slab portion connected to the constraining slab portion in a flexibly bending manner, the contacting slab portion comprising a second engaging structure aligning with the first engaging structure, the second engaging structure being slidably disposed on the supporter so that the contacting slab portion is movable relative to the supporter to press the object toward the bracket, the contacting slab portion comprising a first part, a second part and a third part, two sides of the second part being respectively bent from the first part and the third part, the first part being bent from an edge side of the constraining slab portion and contacting against a lateral surface of the constraining slab portion facing the first part substantially in parallel, the third part being substantially parallel to the first part and utilized to press the object.

2. The detachable fixing mechanism of claim 1 , wherein the first engaging structure comprises a first area, a second area and a third area connected to each other, the second area is located between the first area and the third area, a dimension of the annular sunken slot is greater than a gap of the second area and smaller than gaps of the first area and the third area.

3. The detachable fixing mechanism of claim 1 , wherein a bending direction of the second part relative to the first part is opposite to a bending direction of the third part relative to the second part.

4. detachable fixing mechanism of claim 1 , wherein the actuating component further comprises a handling slab portion disposed on a side of the constraining slab portion opposite to the contacting slab portion.

5. The detachable fixing mechanism of claim 4 , wherein a guiding structure is formed on an edge of the handling slab portion.

6. An electronic device with detachable function, comprising:
a bracket whereon an object is accommodated; and
a detachable fixing mechanism capable of fixing the object on the bracket, the detachable fixing mechanism comprising:
a positioning pin disposed on the bracket, the positioning pin comprising a supporter whereon an annular sunken slot is formed, the supporter being adapted to pierce through an opening on the object; and
an actuating component detachably disposed on the positioning pin, the actuating component comprising:
a constraining slab portion comprising a first engaging structure, the first engaging structure being adapted to engage with the annular sunken slot to constrain a relative movement between the positioning pin and the actuating component; and
a contacting slab portion connected to the constraining slab portion in a flexibly bending manner, the contacting slab portion comprising a second engaging structure aligning with the first engaging structure, the second engaging structure being slidably disposed on the supporter so that the contacting slab portion is movable relative to the supporter to press the object on the bracket, the contacting slab portion comprising a first part, a second part and a third part, two sides of the second part being respectively bent from the first part and the third part, the first part being bent from an edge side of the constraining slab portion and contacting against a lateral surface of the constraining slab portion facing the first part substantially in parallel, the third part being substantially parallel to the first part and utilized to press the object.

7. The electronic device of claim 6 , wherein the first engaging structure comprises a first area, a second area and a third area connected to each other, the second area is located between the first area and the third area, a dimension of the annular sunken slot is greater than a gap of the second area and smaller than gaps of the first area and the third area.

8. The electronic device of claim 6 , wherein a bending direction of the second part relative to the first part is opposite to a bending direction of the third part relative to the second part.

9. The electronic device of claim 6 , wherein the actuating component further comprises a handling slab portion disposed on a side of the constraining slab portion opposite to the contacting slab portion.

10. The electronic device of claim 9 , wherein a guiding structure is formed on an edge of the handling slab portion.

11. An operating method of fixing an object on a bracket with a detachable fixing mechanism, the operating method comprising:
obtaining the detachable fixing mechanism, the detachable fixing mechanism comprising:
a positioning in comprising a supporter whereon an annular sunken slot is formed, the supporter being adapted to pierce through an opening on the object; and
an actuating component adapted to be detachably disposed on the positioning pin, the actuating component comprising:
a constraining slab portion comprising a first engaging structure, the first engaging structure being adapted to engage with the annular sunken slot to constrain a relative movement between the positioning pin and the actuating component; and
a contacting slab portion connected to the constraining slab portion in a flexibly bending manner, the contacting slab portion comprising a second engaging structure aligning with the first engaging structure, the second engaging structure adapted to be slidably disposed on the supporter so that the contacting slab portion is movable relative to the supporter to press the object toward the bracket, the contacting slab portion comprising a first part, a second part and a third part, two sides of the second part being respectively bent from the first part and the third part, the first part being bent from an edge side of the constraining slab portion and contacting against a lateral surface of the constraining slab portion facing the first part substantially in parallel, the third part being substantially parallel to the first part and utilized to press the object;

installing the positioning pin on the bracket;
disposing the object on the positioning pin via the opening of the object; and
fitting the actuating component into the annular sunken slot of the positioning pin such that the contacting slab portion moves relative to the supporter to press the object toward the bracket.
