At least two hinge positions are arranged on the first top joint 134 and the second top joint 144. The first bottom joint 133, the first top joint 134, the second bottom joint 143 and the second top joint 144 are all processed into smooth arc surfaces at the corners, so as to reduce the number of sharp corners of the luggage cart and avoid scratching or scratching people.

[0042] The side frame 10 comprises a plurality of X assemblies, and the number of the X assemblies is at least two. The two X assemblies are arranged side by side. The X assembly is connected by two side connecting rods 101. The side connecting rods 101 of the adjacent two X assemblies are directly rotatably connected through the bending sections 1012 at the ends thereof. The X assembly is hingedly connected with the first bottom joint 133, the second bottom joint 143, the first top joint 134 and the second top joint 144 through the bending sections 1012 at the ends of the side connecting rods 101 close to the front frame 13 or the rear frame 14.

[0043] The front frame 13 comprises two first vertical rods 131 and two first cross tubes 132. The two first vertical rods 131 are arranged side by side and spaced apart. The two first cross tubes 132 are cross-rotatably connected. The two first cross tubes 132 are located between the two first vertical rods 131. The top ends of the two first cross tubes 132 are respectively hingedly connected to first top joints 134 on the respective sides.

The first inner tube is arranged inside the first outer tube and can move axially in the first outer tube. The first top joint 134 is mounted at the top end of the first inner tube. The first bottom joint 133 is mounted at the bottom end of the first outer tube. When the frame 1 needs to be folded, the two first cross tubes 132 are rotated. The first cross tubes 132 drive the first inner tube to move axially along the first outer tube through the first top joint 134, so as to realize folding. When the frame 1 needs to be unfolded, the first top joint 134 is pressed down while the first inner tube is pressed into the first outer tube, so as to drive the two first cross tubes 132 to rotate, thereby realizing unfolding of the frame 1.

[0045] Similarly, the rear frame 14 comprises two second vertical rods 141 and two second cross tubes 142. The two second vertical rods 141 are arranged side by side and spaced apart. The two second cross tubes 142 are cross-rotatably connected. The two second cross tubes 142 are located between the two second vertical rods 141. The top ends of the two second cross tubes 142 are respectively hingedly connected to second top joints 144 on the respective sides. The bottom ends of the two second cross tubes 142 are respectively hingedly connected to second bottom joints 143 on the respective sides. The second vertical rods 141 are also telescopic rods.

[0046] The second vertical rod 141 comprises a second inner tube and a second outer tube. The second inner tube is arranged inside the second outer tube and can move axially in the second outer tube. The second top joint 144 is mounted at the top end of the second inner tube. The second bottom joint 143 is mounted at the bottom end of the second outer tube. When the frame 1 needs to be folded, the two second cross tubes 142 are rotated. The second cross tubes 142 drive the second inner tube to move axially along the second outer tube through the second top joint 144, so as to realize folding. When the frame 1 needs to be unfolded, the second top joint 144 is pressed down while the second inner tube is pressed into the second outer tube, so as to drive the two second cross tubes 142 to rotate, thereby realizing unfolding of the frame 1.

[0047] Optionally, the edges of the first vertical rods 131, the first cross tubes 132, the second vertical rods 141 and the second cross tubes 142 are all rounded, so as to reduce the probability of scratching or scratching people by the luggage cart.

[0048] The bottom frame 11 comprises a bottom joint 112 and four bottom beams 111, the bottom joint 112 is provided with at least four hinge positions, one end of the four bottom beams 111 is respectively hingedly connected to the hinge positions of the bottom joint 112, and the other end of the four bottom beams 111 is respectively hingedly connected to two first bottom joints 133 and two second bottom joints 143, so as to be coordinated in folding or unfolding.

[0049] It is worth mentioning that the front frame 13, the rear frame 14, the side frame 10 and the bottom frame 11 are cooperated in the folding and unfolding of the frame 1.

[0050] The foldable luggage trolley further comprises a pull rod 3, the pull rod 3 comprises branch rods and a main rod, the two branch rods are rotatably connected to the main rod through a hinge, so that the two branch rods can be folded when the frame 1 is folded.
