The plate body 62 is fixed to the rotating frame 61, and the rotating frame 61 is mounted on the rear uprights 42 via the rotating assembly 63. When a long object needs to be transported, the rotating frame 61 can be flipped outward, so that the rear side of the folding frame 11 forms an open state, facilitating the placement of long objects. Specifically, the rotating frame 61 is composed of a pair of vertically disposed vertical tubes 611 and a pair of horizontally disposed transverse tubes 612. The transverse tubes 612 are mounted between the two vertical tubes and are located at the upper and lower ends, respectively. The upper and lower ends of the plate body 62 are respectively fixed to the two transverse tubes 612. At the same time, the rear taillight 52 is also mounted on the lower transverse tube 612. The rotating assembly 63 is positioned between the bottom ends of the two vertical tubes 611 of the rotating frame 61 and the bottom ends of the rear posts 42. It comprises a fixed sleeve 631 and a rotating sleeve 632. The fixed sleeve 631 is fixed to the rear posts 42 and has a fixing hole for inserting the bottom end of the rear posts 42. The bottom end of the rear posts 42 directly extends through the fixing hole to mount the rear wheel 13b. The side of the fixed sleeve 631 also allows for insertion of the rear bottom bar 444 and is secured to the rear bottom bar 444 via screws. The rotating sleeve 632 is screwed to the bottom ends of the vertical tubes 611 and comprises a rotating head 6111 rotatably mounted on the fixed sleeve 631. The fixed sleeve 631 has a rotating groove 6311 for inserting the rotating head 6111. The bottom surface of the rotating groove 6311 also limits the rotation angle of the rotating head 6111, ensuring that the maximum rotation range of the rotating head 6111 is limited until the side surface of the rotating head 6111 is aligned with the bottom surface of the groove.

[0054] FIG5 is a schematic diagram of the rear connecting member installation structure according to the present invention.

[0055] FIG6 is a second schematic diagram of the rear connecting member installation structure of the present invention.

[0056] As shown in FIG4 , a locking button 64 is also movably provided at the upper end of the rotating frame 61. A rear connecting assembly is provided at the upper end of each rear column 42, and the rear connecting assembly has a rear connecting member 71. As shown in FIG5-6 , the rear connecting member 71 has a connecting sleeve 711, a rear connecting portion 712, and a locking portion 713. The connecting sleeve 711 is sleeved on the upper end of the rear column 42 (see FIG4 ), and a sleeve hole is provided in the middle portion for the rear column 42 to extend into. The rear connecting portion 712 is integrally formed on one side of the connecting sleeve 711 and is provided with a slot 7121 for the side frame 43 to extend into. The locking portion 713 is integrally formed on the other side of the connecting sleeve 711 and is provided with a rear locking hole 7131 for the upper end of the locking button 64 to pass through. A spring is provided in the locking button 64 to enable the locking button 64 to be inserted into the rear locking hole 7131. When the upper end of the locking button 64 passes through the rear locking hole 7131, the rotating frame 61 is restrained on the rear column 42, and the plate body 62 is in a vertically retracted state. After pressing the locking button 64 to move it downward and out of the locking hole 7131, the rotating frame 61 can be rotated, thereby rotating the plate body 62 outward to an open state.

[0057] 7 is a cross-sectional view of the rear connecting assembly of the present invention installed on the rear pillar.

[0058] As shown in Figures 5-7, the rear connecting assembly further comprises a rear fixing latch 72, a rear locking pin 73, and a rear fabric frame latch 74. One end of the rear fixing latch 72 is inserted into the rear column 42, and the end of the rear fixing latch 72 inserted into the rear column 42 defines a mounting groove 722. The rear locking pin 73 slides within the mounting groove 722. The rear column 42 defines a rear positioning hole 421 through which one end of the rear locking pin 73 passes. A rear elastic member 75 (optionally a spring) is disposed between the other end of the rear locking pin 73 and the inner wall of the rear column 42. The other end of the rear fixing latch 72 extends beyond the top of the rear column 42 and comprises a boss 721 that abuts against the top of the connecting sleeve 711. Specifically, an abutment ring 7111 protrudes upward from the top of the connecting sleeve 711, and a limiting groove 7112 is defined on the side of the abutment ring 7111. The rear fixing pin 72 is located below the boss 721 and has a limiting bump 723 protruding outward. The limiting bump 723 fits snugly within the limiting groove 7112, and the lower end surface of the boss 721 abuts the top surface of the abutment ring 7111. The cooperation between the limiting groove 7112 and the limiting bump 723 not only limits the circumferential rotation of the rear fixing pin 72, but also serves as a warning, facilitating installation. The rear cloth frame latch 74 is used to install the cloth frame 12 on the rear column 42. A hole for inserting the rear cloth frame latch 74 is provided in the middle of the rear fixed latch 72. A rear hook portion 731 is provided at the upper end of the rear locking pin 73. A rear locking groove 741 that cooperates with the rear hook portion 731 is provided on one end of the rear cloth frame latch 74 inserted into the rear fixed latch 72. When installing the fabric frame 12, the rear fabric frame latch 74 passes through the insertion hole on the fabric frame 12 and extends into the interior of the rear fixing latch 72. Since a rear elastic member 75 is provided between the rear locking pin 73 and the inner wall of the rear column 42, the rear elastic member 75 causes the end of the rear fabric frame latch 74 to contact the rear hook portion 731, causing the rear locking pin 73 to move outward until the rear fabric frame latch 74 moves to the rear locking groove 741 and aligns with the rear hook portion 731. Then, under the action of the rear elastic member 75, the rear hook portion 731 snaps into the rear locking groove 741, completing the installation of the fabric frame latch 74. In order to strengthen the connection stability between the rear connecting member 71, the rear column 42, and the rear fixing latch 72, a fixing pin 422 can also be used to pass through the rear connecting member 71, the rear column 42, and the rear fixing latch 72 in sequence to fix the three together.
