[0007] Preferably, the battery box is an integrated flip-up battery replacement mode on the vehicle frame; it includes a quick lock, a mechanical lock, and an electronic lock, and the integrated battery box is welded to the middle tube to form a whole.
[0008] The effects achieved by the above components are: waterproof, anti-theft and fireproof functions; the battery box makes the car not too wide when folded, which is suitable for special driving vehicles; it is easy to fold and carry like a multi-purpose portable car for daily use; the middle tube and the battery box are integrally formed to make the frame, which is firm, simple and compact.
[0009] Preferably, the frame does not have a chain, and the frame is a chainless version.
[0010] The effect achieved by the above components is that the absence of a chain can further reduce the width of the frame, making it easier to fold the frame.
[0011] Preferably, the middle tube reinforcement plate is made of stainless steel, and the middle tube reinforcement plate is connected to the reinforced middle tube by welding.
[0012] The effects achieved by the above components are: the center tube reinforcement plate can greatly improve the service strength of the reinforced center tube, and this structure is relatively simple and can be easily maintained.
[0013] Preferably, the cross-section of the handle is U-shaped, and the handle is made of stainless steel.
[0014] The effect achieved by the above components is that the frame can be directly moved by pulling the handle, and the handle makes it more convenient to move the frame.
[0015] Compared with related technologies, the fast battery-changing folding frame provided by the present invention has the following beneficial effects:
[0016] This utility model provides a quick-change battery folding frame. By setting up all the structures, the battery box is welded to the center tube to form an integral part of the frame.
