[0002] With the in-depth penetration of the clean energy concept, electric vehicles with electric drive as their core advantage are rapidly reshaping the urban travel ecosystem. Their zero-emission operation characteristics significantly reduce the traffic pollution load, and with policy guidance and improved infrastructure, electric vehicles have become the mainstream choice for short-distance travel in modern cities.

[0003] Existing foldable electric vehicles on the market are generally folded and stored from the middle. When a designated driver folds the foldable electric vehicle and places it in the trunk of the designated driving vehicle, due to the increasingly diversified design of automotive products, the trunks of some compact cars and sports cars are relatively small, while the folded electric vehicle is relatively high as a whole, making it difficult to place in the trunk of some designated driving vehicles with small trunks.

[0030] Working principle: When using this easy-to-fold electric vehicle frame, when the electric vehicle needs to be folded, the cushioning seat 502 first drives the support rod 5 to deflect, so that the support rod 5 drives the two grooves 503 on its side to deflect to the two horizontal blocks on the opposite side of the two T-shaped blocks 701 in a perpendicular state. At this time, the two T-shaped blocks 701 close in the middle by the rebound force of the tension spring 702, thereby releasing the fixed state of the two T-shaped blocks 701 on the slot 401. Then, the two connecting strips 4 are moved to the left along the long groove 3 to the extreme position. Next, the support rod 5 drives the grooves 503 to deflect and reset, so that the two T-shaped blocks 701 open to the front and back sides, and the two horizontal blocks on the opposite side of the T-shaped blocks 701 move to the inside of the two rightmost slots 401, thus completing the folding and fixing of the electric vehicle, reducing the height of the electric vehicle after folding, and making it easier to fit into the trunk of a smaller vehicle. By rotating the groove 503 with the support rod 5, the side of the groove 503 moves to a position where the two horizontal bars on the opposite side of the T-shaped block 701 are in contact. At this point, the fixing between the frame assembly 1 and the connecting strip 4 is released. Then, the length of the connecting strip 4 on the side of the frame assembly 1 is adjusted according to the user's height, so that the frame assembly 1 and the connecting strip 4 are moved to a comfortable riding length for the user. Next, the groove 503 is rotated again with the support rod 5, and the side of the support rod 5 contacts the side of the T-shaped block 701, so that the two horizontal bars on the opposite side of the two T-shaped blocks 701 move into the appropriate slot 401. The adjusted electric vehicle frame can then be quickly fixed, making it convenient for users of different heights to ride comfortably.
