[0039] In this embodiment, the first polygonal region 8 and the second polygonal region 9 on the top cover 1 can be provided with mounting holes to facilitate the installation of the tail box 23.

[0040] In this embodiment, the plastic parts on the rear cargo rack 6 can be fitted with a tail box 23, a saddle 24, and a backrest 25 as needed during later use, so that the rear cargo rack 6 can switch between carrying goods and carrying people.

[0041] Furthermore, as a preferred embodiment, it also includes a wire clip 11 and a insert 12. The upper end of the lower cover 2 is provided with a wire clip 11 for fixing the wiring harness of the taillight 3.

[0042] like Figure 3As shown, one end of the lower cover 2 is provided with two inserts 12 for attaching to the upper end of the taillight 3. In this embodiment, the wire clip 11 is used to fix the wiring harness of the taillight 3, which can prevent the wiring harness from being damaged by the rear cargo rack 6 during assembly in a compact space. The two inserts 12 can also be used to position the lower cover 2, facilitating the assembly between the lower cover 2 and the taillight 3. The back of the insert 12 is a third polygonal region 10. The specific shapes of the first polygonal region 8, the second polygonal region 9, and the third polygonal region 10 in this embodiment can be found in [reference needed]. Figure 6 and Figure 9 As shown.

[0043] Furthermore, as a preferred embodiment, it also includes a first screw 13, a first connecting piece 16 at the upper end of the taillight 3, and a second connecting piece 17 correspondingly located at the middle of one end of the lower cover 2. The first screw 13 passes through the rear cargo rack 6, the first connecting piece 16, and the second connecting piece 17. See also Figure 3 and Figure 4 As shown, when assembling the lower cover 2 and the taillight 3, the first connecting piece 16 on the taillight 3 overlaps the second connecting piece 17, and a screw hole for the first screw 13 to pass through is opened at the corresponding position on the rear cargo rack 6. The first screw 13 passes through the screw hole, the first connecting piece 16 and the second connecting piece 17, thereby connecting and fixing the lower cover 2, the taillight 3 and the rear cargo rack 6.

[0044] Furthermore, as a preferred embodiment, each card plate 5 includes several equally spaced limiting plates 18, and one side wall of each limiting plate 18 is arc-shaped. It also includes locking blocks 19; two locking blocks 19 are provided on both sides of the lower cover 2, and the locking blocks 19 can engage between two adjacent limiting plates 18. In this embodiment, the locking blocks 19 can engage between two limiting plates 18 to achieve locking and limiting. The arc shape on the limiting plate 18 is used to cooperate with the first circular tube 7 on the rear shelf 6.

[0045] Furthermore, as a preferred embodiment, it also includes a second screw 14, which connects the lower cover 2 and the upper cover 1. Four second screws 14 are provided, and each second screw 14 passes through the lower cover 2 from bottom to top and connects to the upper cover 1. The second screws 14 do not penetrate the upper cover 1, allowing them to be hidden inside the upper cover 1, achieving a simple and aesthetically pleasing design for the rear rack 6.

[0046] Furthermore, as a preferred embodiment, a third screw 15 is also included, which connects the rear cargo rack 6 and the taillight 3. A clip nut 20 is provided between the taillight 3 and the rear cargo rack 6, and the third screw 15 passes through the clip nut 20. Two third screws 15 are provided to fix the connection between the rear cargo rack 6 and the taillight 3.

[0047] Furthermore, as a preferred embodiment, the rear rack 6 is provided with a concave groove 21 in the middle.

[0048] During installation, first install the clip nut 20 onto the taillight 3. Then, use the third screw 15 to install and fix the rear cargo rack 6 to the taillight 3. Next, press the wiring harness on the taillight 3 into the wire clip 11 to secure the wiring harness of the taillight 3. Then, insert the insert 12 on the lower cover 2 above the taillight 3 and overlap it on the taillight 3. Using this as a fulcrum, rotate upwards to assemble. Finally, use the first screw 13 to connect and fix the rear cargo rack 6, taillight 3, and lower cover 2. Next, install the top cover 1, placing it vertically downwards. Engage the two hooks 4 on the top cover 1 into the rear shelf connecting plate 29 on the rear shelf 6 to create a snap-fit ​​design, ensuring a uniform fit between the top cover 1 and the rear shelf 6 without warping. The retaining plate 5 on the top cover 1 engages with the first round tube 7 of the rear shelf 6. The retaining plate 5 and the retaining block 19 on the rear shelf 6 cooperate to restrict the outward expansion of the plastic parts and the lateral fit between the top cover 1 and the rear shelf 6, further preventing unevenness caused by outward expansion of the plastic parts. Then, install the second screw 14 from bottom to top to connect the top cover 1 and the bottom cover 2.

[0049] After assembly, if the consumer wants to use the rear cargo rack 6, they should first remove the second screw 14 on the lower cover 2, then pull up the four corners of the upper cover 1 to remove the upper cover 1.

[0050] When using the tail box 23, the four round holes 22 on the top cover 1 can be cut off with a cutting tool (such as a utility knife). Then, the top cover 1 is assembled onto the rear cargo rack 6. The bottom cover 2 is secured from bottom to top with four second screws 14. The tail box 23 is placed on top of the top cover 1 and aligned with the four round holes 22. Four fourth screws 26 are installed from inside the tail box 23 to fix the tail box 23 onto the rear cargo rack 6.

[0051] When using the saddle 24 (rear saddle), the lower cover 2 needs to be removed for the first time. Use a cutting tool (such as a utility knife) to cut off the first polygonal area 8 of the upper cover 1 and the third polygonal area 10 of the lower cover 2 along the cutting line. Then, assemble the upper cover 1 and the lower cover 2 onto the rear rack 6. Then, assemble the saddle 24 from back to front, so that the hook 30 of the saddle 24 engages with the concave groove 21 of the rear rack 6. Then, assemble the two fifth screws 27 from bottom to top to fix the saddle 24.

[0052] When used with the backrest 25, the second polygonal area 9 on the top cover 1 can be cut off along the cutting line using a cutting tool (such as a utility knife). Then, the top cover 1 is assembled to the rear shelf 6, and the backrest 25 is placed at the rear of the rear shelf 6 and secured with three sixth screws 28.
