The four end points of the bottom folding frame 4 are hinged in four lower fixed blocks 7. The horizontal folding frame 2 and the vertical folding frame 3 are folded by sliding the slider 8 up and down, and the bottom folding frame 4 is driven to fold at the same time. The folding or unfolding method is relatively simple, which meets the convenience of user use. When folding, the horizontal folding frame 2 can drive the two horizontal columns 1 to fold together, the vertical folding frame 3 can drive the two vertical columns 1 to fold together, and the bottom folding frame 4 gathers and folds upwards, so that multiple sides of the folding bicycle can be folded, further reducing the volume occupied after folding, making it convenient for users to carry when going out.

[0025] A connecting rope 9 is provided between the horizontal folding frame 2 and the bottom folding frame 4, and the two ends of the connecting rope 9 are respectively fixed on the horizontal folding frame 2 and the bottom folding frame 4. The connecting rope 9 is used to further reinforce the folding cart, increase the stability of the cart during driving, and avoid the shaking of the frame to bring a bad experience to the user. The two frames are connected by the connecting rope 9. The rope has good tension. When the cart shakes when driving on an uneven road, the rope will slightly expand and contract due to its own tension, reducing the pressure on the connection of the connecting rope 9, avoiding long-term shaking and causing the connection to loosen or even fall off. In addition, the connecting rope 9 is used to connect the horizontal folding frame and the bottom folding frame. Compared with the pole connection, the rope is smaller in size and can be folded arbitrarily, so that the space occupied by the cart after folding is smaller.

[0026] The horizontal folding frame 2 shown includes three pairs of hingedly connected horizontal cross frames 10, and the vertical folding frame 3 includes two pairs of hingedly connected vertical cross frames 11; the bottom folding frame 4 includes two pairs of bottom frame assemblies 12 and a connecting block 13 located between two adjacent bottom frame assemblies 12, the inner end of the bottom frame assembly 12 is hinged on the connecting block 13, and the two bottom frame assemblies 12 are connected through the connecting block 13, and the outer end of the bottom frame assembly 12 is hinged on the lower fixed block 7.
