The working principle of the ultra-light folding electric bicycle is as follows: namely, when a designated driver receives a designated driving order and needs to fold the device and put the device into a rear spare compartment of a vehicle needing designated driving, the device can rotate through the connecting frame 3 and the mounting frame 4, so that the front frame 1 and the rear frame 2 rotate through the connecting part 5 of the connecting frame 3 and the mounting frame 4, and the length of the connecting part of the connecting frame 3 and the mounting frame 4 can be changed, namely the overlapped part can be changed, so that the length of the front frame 1 and the rear frame 2 after being folded can be further changed after being folded, and when the device is used for riding, the length of the whole frame can be changed by changing the length of the overlapped part of the front frame 1 and the rear frame 2, so that the axle distance between the front wheel and the rear wheel can be maximized, the riding safety is improved, the volume of the whole frame after being folded can be minimized while riding, namely, extremely short riding is realized on the premise of not influencing the safety, Narrowing, so that the trolley can be placed into the spare compartments of all trolleys after being folded, thereby meeting the requirements of customers, improving the professional level and service experience, and improving the ordering efficiency of designated driving workers.

In this embodiment, the end of the connecting frame 3 is bent upwards to form a horizontal connecting part 5, and the upper end surface of the mounting frame 4 forms a horizontal contact surface 6; the lower end surface of the connecting portion 5 is attached to the upper end surface of the contact surface 6. Make connecting portion 5 position of connecting frame 3 and mounting bracket 4 be the horizontality promptly to avoid connecting frame 3 and contact surface 6 to connect the back, the easy appearance is separated mutually or the slip condition in opposite directions, thereby guarantee the safety of riding, improve the security of the in-process of riding.

In this embodiment, the connecting portion 5 is provided with a strip-shaped groove 7; the contact surface 6 is provided with a plurality of jacks 8 corresponding to the strip-shaped grooves 7; a supporting rod 9 inserted with the strip-shaped groove 7 is arranged at the left end part of the contact surface 6, and the end part of the supporting rod 9 extending out of the strip-shaped groove 7 is detachably connected with a limiting ring 10; a limiting part which can penetrate through the strip-shaped groove 7 and is connected with the jack 8 in an inserting mode is further arranged in the strip-shaped groove 7. After the lower end face of connecting portion 5 and the up end laminating of contact surface 6 promptly, on the one hand through the grafting of branch 9, make preceding frame 1 and back frame 2 can rotate, folding, and insert the locating part to bar groove 7 in and during inserting corresponding jack 8, can be fixed with preceding frame 1 and back frame 2 promptly, and when needs are folding, tear down the locating part promptly can, and when the wheel base of two wheels needs to be changed, select corresponding jack 8 promptly, insert the locating part and can realize promptly.

And from the whole car on, branch 9 is located near preceding frame 1 setting at the junction of link 3 and mounting bracket 4, and is close to back frame 2 during the locating part, makes like this when riding, and branch 9 can bear main gravity, and the one end of branch 9 is with mounting bracket 4 rigid coupling, and the other end can be the rigid coupling, under the prerequisite that guarantees overall structure is firm, also can dismantle the connection, and then make by the metal in the aspect of the material. So as to ensure that the whole frame has enough strength when riding.

In this embodiment, the limiting member includes an insertion rod 11 and a plug located at an end of the insertion rod 11, and a bottom inner wall of the insertion hole 8 extends outward to form an annular groove 23 abutting against the end of the plug. Namely, the limiting piece penetrates through the strip-shaped groove 7 and is inserted into the corresponding jack 8, and the end part of the plug connector is placed into the annular groove 23 to perform limiting action, so that the purposes of the front frame 1 and the rear frame 2 are achieved.

In this embodiment, the plug connector is located in the installation cavity 12 of the limiting member, and includes a limiting spring 13 and a limiting block 14 connected in sequence from inside to outside. Through spacing spring 13 and stopper 14, can realize the connection dismantled of locating part in bar groove 7 and jack 8 promptly to be convenient for whole frame folding and ride, simple and practical. And the quantity of plug connector is provided with 4 in this embodiment to evenly set up along the circumferencial direction of inserted bar 11, of course, also can be appropriate increase the quantity of plug connector to improve the steadiness between locating part and jack 8.

In this embodiment, a limiting plate 15 is disposed between the limiting spring 13 and the limiting block 14, and an end of the mounting cavity 12 extends inward to form a limiting projection 16 for preventing the limiting plate 15 from separating from the mounting cavity 12. By utilizing the limiting plate 15 and the limiting lug 16, the limiting spring 13 cannot be separated from the mounting cavity 12, so that the mounting and the dismounting are convenient, and the overall practicability is improved.
