Abstract

A fixing mechanism with quick-releasing function for assembling a cover with a base includes a buckling component and an actuating component. The buckling component includes a main body, a first wedging portion, a hooking portion and a pushing portion. The first wedging portion is disposed on a hole on the main body. The hooking portion and the pushing portion are disposed on the main body and respectively protrude from the main body at different directions. The actuating component includes a shaft body and a second wedging portion. The hooking portion is engaged with a constraining portion of the base to constrain a movement between the base and the cover while the buckling component is in the first position. The pushing portion pushes the constraining portion to separate the base and the cover while the buckling component is in the second position.

First claim

What is claimed is:

1. A fixing mechanism with quick-releasing function for assembling a cover with a base, the fixing mechanism comprising:
a buckling component, comprising:
a main body whereon a hole is formed;
a first wedging portion formed on an inner wall of the hole;
a hooking portion disposed on the main body and stretching from the main body outwardly at a first direction, the hooking portion being adapted to engage with a constraining portion of the cover; and
a pushing portion disposed on a position of the main body adjacent to the hooking portion and stretching from the main body outwardly at a second direction different from the first direction, the pushing portion being adapted to push the constraining portion; and

an actuating component adapted to drive rotation of the buckling component, the actuating component comprising:
a shaft body piercing through the hole and rotatably disposed on the base; and
a second wedging portion formed on the shaft body and wedged with the first wedging portion, the shaft body being adapted to revolve on a structural axial direction of the shaft body to switch the buckling component between a first position and a second position, the hooking portion being engaged with the constraining portion to constrain a relative movement between the cover and the base while the buckling component is located in the first position, the pushing portion pushing the constraining portion to separate the cover from base while the buckling component is located in the second position.

2. The fixing mechanism of claim 1 , wherein the hooking portion is engaged with a constrained surface of the constraining portion, and the pushing portion pushes a pressed surface of the constraining portion different from the constrained surface.

3. The fixing mechanism of claim 1 , wherein a level height difference between the hooking portion and an axial center of the hole is greater than a level height difference between the pushing portion and the axial center while the buckling component is located in the first position, the level height difference between the hooking portion and the axial center is smaller than the level height difference between the pushing portion and the axial center while the buckling component is located in the second position.

4. The fixing mechanism of claim 1 , wherein the hooking portion is engaged with the constraining portion while the buckling component is located in the first position, the hooking portion is separated from the constraining portion and the pushing portion presses the constraining portion while the buckling component is located in the second position.

5. The fixing mechanism of claim 1 , further comprising:
a fixing component disposed on the base and pressing upon the actuating component and/or the buckling component.

6. The fixing mechanism of claim 5 , wherein the buckling component further comprises a contacting portion disposed on a side of the main body opposite to the pushing portion, the contacting portion leans against the fixing component to constrain rotation of the buckling component.

7. The fixing mechanism of claim 6 , wherein the fixing component comprises a yielded structure and an abutted structure, the yielded structure provides rotary space to the contacting portion, and the contacting portion leans against the abutted structure.

8. The fixing mechanism of claim 6 , wherein the main body comprises a first side, a second side and a third side connected with each other, the first side is connected between the second side and the third side, the hooking portion is disposed on the first side, the pushing portion and the contacting portion are respectively disposed on the second side and the third side and opposite to each other.

9. The fixing mechanism of claim 1 , wherein the shaft body comprises a first section, a second section and a third section, the second section is located between the first section and the third section, the second wedging portion is disposed on the second section, the first section and the third section are rotatably disposed on the base.

10. The fixing mechanism of claim 9 , wherein the shaft body further comprises at least one annular slot structure disposed on the first section and/or the third section to be rotatably engaged with the base.

11. The fixing mechanism of claim 1 , further comprising:
a resilient component disposed on the shaft body, two ends of the resilient component respectively leaning against the base and the buckling component.

12. The fixing mechanism of claim 11 , wherein a slide slot structure is formed on the pushing portion, an end of the resilient component is movably disposed inside the slide slot structure.

13. The fixing mechanism of claim 11 , wherein the resilient component is a torsional spring.

14. An electronic device with quick-releasing function, comprising:
a base adapted to support a plurality of electronic components;
a cover assembled with the base to cover the plurality of electronic components, the cover comprising a constraining portion; and
at least one fixing mechanism disposed on the base, the fixing mechanism comprising:
a buckling component, comprising:
a main body whereon a hole is formed;
a first wedging portion formed on an inner wall of the hole;
a hooking portion disposed on the main body and stretching from the main body outwardly at a first direction, the hooking portion being adapted to engage with the constraining portion; and
a pushing portion disposed on a position of the main body adjacent to the hooking portion and stretching from the main body outwardly at a second direction different from the first direction, the pushing portion being adapted to push the constraining portion; and

an actuating component adapted to drive rotation of the buckling component, the actuating component comprising:
a shaft body piercing through the hole and rotatably disposed on the base; and
a second wedging portion formed on the shaft body and wedged with the first wedging portion, the shaft body being adapted to revolve on a structural axial direction of the shaft body to switch the buckling component between a first position and a second position, the hooking portion being engaged with the constraining portion to constrain a relative movement between the cover and the base while the buckling component is located in the first position, the pushing portion pushing the constraining portion to separate the cover from base while the buckling component is located in the second position.

15. The electronic device of claim 14 , wherein the hooking portion is engaged with a constrained surface of the constraining portion, and the pushing portion pushes a pressed surface of the constraining portion different from the constrained surface.

16. The electronic device of claim 14 , wherein a level height difference between the hooking portion and an axial center of the hole is greater than a level height difference between the pushing portion and the axial center while the buckling component is located in the first position, the level height difference between the hooking portion and the axial center is smaller than the level height difference between the pushing portion and the axial center while the buckling component is located in the second position.

17. The electronic device of claim 14 , wherein the hooking portion is engaged with the constraining portion while the buckling component is located in the first position, the hooking portion is separated from the constraining portion and the pushing portion presses the constraining p
