a first structural member pivotally connected with the pivoting joint module, the first structural member being adapted to switch between a folded position and an unfolded position;

a second structural member pivotally connected with the pivoting joint module and opposite to the first structural member, the second structural member being adapted to switch between the folded position and the unfolded position; and

a plurality of legs comprising a first leg and a second leg pivotally connected with two ends of the first structural member, and further comprising a third leg and a fourth leg pivotally connected with two ends of the second structural member; and

an upper frame assembled with the lower frame, the upper frame comprising:

a plurality of holders comprising a first holder and a second holder respectively disposed on the first leg and the second leg, and further comprising a third holder and a fourth holder respectively disposed on the third leg and the fourth leg;

a fixed end structure, two ends of the fixed end structure being respectively disposed on the first holder and the second holder;

a foot structure connected between the third holder and the fourth holder, the foot structure being moved far from the fixed end structure while the first structural member and the second structural member are switched to the unfolded position, and being further moved close to the fixed end structure while the first structural member and the second structural member are switched to the folded position; and

a pivoting end panel pivotally connected with the foot structure, the pivoting end panel is rotated to an upward position for enclosing an accommodating space of the travel bassinet and further rotated to a downward position for enlarging the accommodating space.

2. The travel bassinet of claim 1 , wherein the pivoting joint module is lifted and lowered to switch the first structural member and the second structural member between the folded position and the unfolded position.

3. The travel bassinet of claim 1 , wherein the pivoting end panel comprises a main body and a hinge portion, and the hinge portion is disposed on an edge of the main body and engaged with the foot structure.

4. The travel bassinet of claim 1 , wherein the pivoting end panel comprises a main body, a support foot, a support foot latch, a panel latch and a release handle, the support foot is rotatably disposed on the main body, the support foot latch is movably disposed on the main body, the panel latch is movably disposed on the main body, the release handle is slidably disposed on the main body and connected with the support foot latch and the panel latch.

5. The travel bassinet of claim 4 , wherein the release handle stays in a lock position to contact the support foot latch against the support foot so as to keep the support foot in a hiding position, and further to engage the panel latch with an engaging portion disposed on one of the third holder and the fourth holder so as to fasten the pivoting end panel on the upward position.

6. The travel bassinet of claim 5 , wherein the release handle is moved from the lock position to an unlock position to disengage the panel latch from the engaging portion, and further to separate the support foot latch from the support foot.

7. The travel bassinet of claim 4 , wherein the pivoting end panel further comprises a torsional spring disposed between the support foot and the main body, and a recovering force of the torsional spring is adapted to rotate the support foot from a hiding position to an exposing position.

8. The travel bassinet of claim 1 , wherein the pivoting end panel is covered by fabric material.

9. The travel bassinet of claim 1 , wherein the upper frame further comprises a first side structure and a second side structure respectively located between the fixed end structure and the foot structure.

10. The travel bassinet of claim 9 , wherein the first side structure and the second side structure are detachably disposed on the plurality of holders.

11. The travel bassinet of claim 9 , wherein the upper frame further comprises a plurality of corner uprights respectively disposed on the plurality of holders, the first side structure and the second side structure are connected with the fixed end structure and the foot structure via the plurality of corner uprights.

12. The travel bassinet of claim 11 , wherein the first side structure comprises a pivot portion and two bar portions, two ends of each bar portion are respectively connected with the pivot portion and one of plurality of corner uprights.

13. The travel bassinet of claim 12 , wherein the two bar portions are parallel while the first structural member and the second structural member stay in the unfolded position, and are rotated relative to the pivot portion in a non-parallel state while the first structural member and the second structural member stay in the folded position.

14. The travel bassinet of claim 12 , wherein the two bar portions are rotated downwardly or laterally while the first structural member and the second structural member are switched from the unfolded position to the folded position.

15. The travel bassinet of claim 12 , wherein the pivoting joint module is moved upward to drive rotation of the two bar portions relative to the pivot portion, so as to approach the fixed end structure and the foot structure by folding the first structural member and the second structural member accordingly.

16. The travel bassinet of claim 1 , wherein the pivoting joint module comprises a plate portion with two axle holes, and the first structural member and the second structural member are respectively assembled with the two axle holes.

17. The travel bassinet of claim 16 , wherein the pivoting joint module further comprises a protruding portion disposed under the plate portion.

18. The travel bassinet of claim 16 , wherein the first structural member and the second structural member are folded and unfolded vertically to approach the fixed end structure and the foot structure.

19. The travel bassinet of claim 1 , wherein one of the upper frame and the lower frame is attached to a play yard frame to suspend the travel bassinet above a floor.
