[0020] Example 1, Reference Figure 1-7 A specific embodiment of this utility model provides a universal rear coat rack, including an aluminum alloy body. The aluminum alloy body includes an aluminum alloy curved tube frame 1, a front multi-functional mounting plate 21, and a rear multi-functional mounting plate 15. The aluminum alloy curved tube frame 1 is mounted on the vehicle frame. The front multi-functional mounting plate 21 is fixedly connected (welded) to the top of the front end of the aluminum alloy curved tube frame 1, and the rear multi-functional mounting plate 15 is fixedly connected (welded) to the top of the rear end of the aluminum alloy curved tube frame 1. The seat cushion 6 or the tail box (not shown in the figure) is detachably connected to the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15.

[0021] Most electric vehicles on the market are currently made of cast iron. Cast iron frames are too heavy, easily causing the overall vehicle weight to exceed the standard. In addition, they are not easily compatible and mostly only have a cargo-carrying function. In this application, the aluminum alloy bent tube frame 1, the front multi-functional mounting plate 21, and the rear multi-functional mounting plate 15 are all made of die-cast aluminum alloy, which is lightweight and high-strength, meeting the latest national standard (GB17761-2024). In addition, the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15 can not only install the seat 6, but also replace the seat 6 with a tail box, which is not limited to the cargo-carrying function and has universal expansion performance, further improving the convenience of electric vehicles.

[0022] The front end mentioned in this application refers to the forward direction of the electric vehicle, and the rear end refers to the backward direction of the electric vehicle.

[0023] Further optimization of the solution also includes a sheet metal rear coat rack cover 5, which is detachably connected to the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15. The seat cushion 6 is detachably connected to the sheet metal rear coat rack cover 5, the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15.

[0024] refer to Figure 1-2 4, 6-7, When installing the seat cushion 6 above the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15, the sheet metal rear coat rack cover plate 5 is installed between the seat cushion 6 and the front multi-functional mounting plate 21 and the rear multi-functional mounting plate 15; the sheet metal rear coat rack cover plate 5 mainly serves a protective function. Specifically, the periphery of the sheet metal rear coat rack cover plate 5 extends downward and is flanged from bottom to inside to prevent scratching hands when moving the vehicle.

[0025] Further optimization of the scheme also includes front mounting bolts 19 and rear mounting bolts 20. The front end of the sheet metal rear coat rack cover 5 is mounted on the front multi-functional mounting plate 21 by two sets of front mounting bolts 19, and the rear end of the sheet metal rear coat rack cover 5 is mounted on the rear multi-functional mounting plate 15 by two sets of rear mounting bolts 20.

Then, the seat cushion 6 is moved from front to back so that all the snap-fit ​​blocks 8 are snapped into the first U-shaped notch 14 on the side of the second through hole 13 and into the second U-shaped notch 16 on the side of the rear multi-functional mounting plate 15. Then, the bolts are passed through the rear multi-functional mounting plate 15 and the sheet metal rear coat rack cover plate 5 in sequence, and finally threaded to the bottom of the seat cushion 6. The sheet metal rear coat rack cover plate 5 has a first seat cushion mounting hole 17, and the rear multi-functional mounting plate 15 has a second seat cushion mounting hole 22. The bolts are passed through the second seat cushion mounting hole 22 and the first seat cushion mounting hole 17 in sequence from bottom to top, and then threaded to the bottom of the seat cushion 6.

[0032] Further optimization of the scheme also includes U-shaped grooves 9. U-shaped grooves 9 are provided on the side wall of the snap-fit ​​block 8. All U-shaped grooves 9 are snapped into the first U-shaped notch 14 and the second U-shaped notch 16 from front to back.

[0033] refer to Figure 3-4 6. The opening directions of the U-shaped groove 9, the first U-shaped notch 14 and the second U-shaped notch 16 are all facing forward. During the process of moving the seat cushion 6 from front to back, all the U-shaped grooves 9 are simultaneously inserted into the first U-shaped notch 14 and the second U-shaped notch 16 from front to back. At this time, the seat cushion 6 can only move forward, and other directions are restricted. Then, the seat cushion 6 is fixed to the rear multi-functional mounting plate 15 and the sheet metal rear clothes rack cover plate 5 by bolts, and the seat cushion 6 is completely restricted.
