Chassis structure

1. A chassis structure, comprising:

a chassis body; and

at least one holder module, comprising:

a frame, located in the chassis body and having a first linking portion and a second linking portion, wherein the frame is adapted to carry an electronic module; and

a guiding assembly, disposed on the chassis body and having a first guiding slot and a second guiding slot, wherein the second guiding slot has a first segment and a second segment, the first guiding slot and the first segment extend along a straight direction, the second segment extends along an arched direction, the first linking portion is slidably disposed in the first guiding slot, the second linking portion is slidably disposed in the second guiding slot,

wherein the first linking portion and the second linking portion are adapted to move along the first guiding slot and the first segment respectively at the same time such that the frame moves upward from a first position to a second position, and then the second linking portion is adapted to move along the second segment such that the frame rotates to a third position by taking the first linking portion as a rotation axis.

2. The chassis structure as claimed in claim 1 , wherein the first guiding slot has a first bottom end and a first top end opposite to each other, the second guiding slot has a second bottom end and a second top end opposite to each other, a moving range of the first linking portion is limited between the first bottom end and the first top end, and a moving range of the second linking portion is limited between the second bottom end and the second top end.

3. The chassis structure as claimed in claim 2 , wherein the first bottom end is aligned to the second bottom end, and the first top end is aligned to a juncture between the first segment and the second segment.

4. The chassis structure as claimed in claim 2 , wherein when the frame is located at the first position, the first linking portion and the second linking portion are respectively located at the first bottom end and the second bottom end.

5. The chassis structure as claimed in claim 2 , wherein when the frame is located at the second position, the first linking portion and the second linking portion are respectively located at the first top end and the juncture between the first segment and the second segment.

6. The chassis structure as claimed in claim 2 , wherein when the frame is located at the third position, the first linking portion and the second linking portion are respectively located at the first top end and the second top end.

7. The chassis structure as claimed in claim 2 , wherein a center of curvature of the second segment is located at the first top end.

8. The chassis structure as claimed in claim 1 , wherein the chassis body has a bottom surface, and an extending direction of the first guiding slot and the first segment is perpendicular to the bottom surface.

9. The chassis structure as claimed in claim 1 , wherein the at least one holder module comprises a handle, the handle is pivoted to the chassis body and is connected to the frame, and the handle is adapted to rotate relative to the chassis body to drive the frame to move to the first position, the second position, and the third position.

10. The chassis structure as claimed in claim 9 , wherein the handle has a slot, the frame has a connecting portion, and the connecting portion is slidably disposed in the slot.

11. The chassis structure as claimed in claim 1 , wherein the guiding assembly comprises a first rack body and a second rack body, the first rack body and the second rack body are fixed to the chassis body, the first guiding slot is formed on the first rack body, and the second guiding slot is formed on the second rack body.

12. The chassis structure as claimed in claim 1 , wherein the chassis structure is suitable for a server, and the electronic module is a hard disk module.
