A second connecting plate 21 is fixedly arranged between the base frame rods 2, a connecting plate 3 is arranged at one end of the base frame rod 2, and one end of the connecting plate 3 is hinged to the connecting cylinder 5. A seat frame rod 4 is arranged on one side of the side frame rod 1, and a fixing plate 6 is snapped onto the seat frame rod 4, and the fixing plate 6 can be snapped onto the base frame rod 2.

[0034] The side frame rod 1 is also fixedly provided with two limiting plates 7 and a support plate 15. The side frame rod 1 is also connected to a support rod, which can be stored and installed on the limiting plate 7.

[0035] The first connecting plate 11 is located between the side frame rods 1. Its main function is to support and fix the two side frame rods 1 to ensure that the distance between them remains unchanged, thereby enhancing the lateral stability of the frame. Similarly, the second connecting plate 21 is located between the bottom frame rods 2, which supports and fixes the bottom frame rods 2 to ensure the parallelism and stability between the bottom frame rods 2. The area between the bottom frame rods 2 and the side frame rods 1 is used to place the electric bicycle battery. The connecting cylinder 5 is used to install the integrated handlebars and the front wheel.

[0036] The side frame rod 1 is inverted L-shaped, and the inner side of the side frame rod 1 is symmetrically provided with limit blocks 12. A through hole 13 is opened through the limit block 12. The seat frame rod 4 is U-shaped, and both ends of the seat frame rod 4 are inserted into the through hole 13.

[0037] Each of the limiting blocks 12 is threaded with a screw 14, and one end of the screw 14 is threaded through and installed on the seat frame rod 4. When both ends of the seat frame rod 4 are inserted into the through holes 13, the screw 14 is tightened to fix the seat frame rod 4, ensuring a firm connection between the seat frame rod 4 and the side frame rod 1, and providing stability and safety for the frame.

[0038] The fixing plate 6 has a first slot 61 and a second slot 62 at both ends. Both ends of the seat rod 4 are engaged in the first slot 61. A first support rod 63 is engaged in the second slot 62. The other end of the first support rod 63 is engaged in the side wall of the side frame rod 1 to further improve the connection strength between the seat rod 4 and the side frame rod 1.

[0039] It should be noted that the side wall of the side frame rod 1 is provided with a slot that engages with the other end of the first support rod 63, which can ensure that the first support rod 63 is engaged in the slot.

[0040] A second support rod 8 is snapped onto the side wall of one of the support plates 15. The other end of the second support rod 8 is snapped onto the second connecting plate 21 to further improve the connection strength between the base frame rod 2 and the side frame rod 1. Both the first support rod 63 and the second support rod 8 are arc-shaped.

[0041] The limiting plate 7 is symmetrically provided with a first groove 71, and the limiting plate 7 is also provided with a second groove 72. A first elastic band 73 is fixedly provided on the first groove 71. Both the first groove 71 and the second groove 72 are arc-shaped grooves. A second elastic band 74 is fixedly provided on the second groove 72.

[0042] A mounting cylinder 22 is welded to one end of the base frame rod 2. The mounting cylinder 22 is used to install the foot pedal. A slot 222 is opened through the mounting cylinder 22. A plug block 31 is fixedly installed at one end of the connecting plate 3. The plug block 31 is inserted into the slot 222. When the plug block 31 is fully inserted into the slot 222, a stable connection is formed between the connecting plate 3 and the base frame rod 2. This not only simplifies the assembly process of the frame, but also improves the overall strength and stability of the frame structure.

[0043] When the frame is stored, the first support rod 63 is set in the first groove 71, and the second support rod 8 is set in the second groove 72. The arc-shaped design of the groove allows the support rod to fit tightly into it, preventing shaking or displacement during storage. The elastic band is used to fix the support rod, binding it in the groove to prevent it from loosening or falling off during storage.

[0044] When storing the frame, pull the insert 31 out of the slot 222. Due to the hinged connection between the connecting plate 3 and the connecting cylinder 5, rotate the connecting plate 3 upwards to bring it closer to the first connecting plate 11. Due to the hinged connection between the base frame rod 2 and the side frame rod 1, rotate the base frame rod 2 upwards to bring it closer to the already rotated connecting plate 3. During this process, the mounting cylinder 22 will naturally be located below the connecting plate 3. Then, place the seat frame rod 4 on the base frame rod 2. In order to fix the position of the seat frame rod 4, and with both ends of the base frame rod 2 engaged in the second slot 62, all the components of the frame are tightly fitted together, greatly saving storage space.

[0045] A fixing rope 221 is provided through the mounting cylinder 22, with one end passing through the inside of the mounting cylinder 22 and fixed to the other side, forming a circular path around the mounting cylinder 22. The fixing rope 221 is used to fix the base frame rod 2 and the connecting plate 3 when storing the frame, which helps to prevent the frame from moving or deforming unnecessarily during storage or transportation, thereby protecting the integrity and safety of the frame.

[0046] In practical use, when installing the frame, one end of the connecting plate 3 is inserted and fixed into the slot 222 in the mounting cylinder 22 on the base frame rod 2 via the insert block 31. Both ends of the seat frame rod 4 are inserted into the through holes 13 on the side frame rod 1 and fixed by tightening the screws 14. Next, the fixing plate 6 is installed on the seat frame rod 4, with both ends of the seat frame rod 4 engaged in the first slot 61. One end of the first support rod 63 is engaged in the second slot 62, and the other end is engaged in the side frame rod 1. One end of the second support rod 8 is engaged in the support plate 15, and the other end is engaged in the base frame rod 2. When storing the frame, the first support rod 63 and the second support rod 8 are removed, and the first support rod 63 and the second support rod 8 are then connected together. The rods 8 are placed in the first groove 71 and the second groove 72 on the limiting plate 7, and the elastic rope binds the support rod in the groove. Loosen the screw 14 to pull the insert 31 out of the slot 222. After pulling the insert 31 out of the slot 222, rotate the connecting plate 3 upward so that it approaches the first connecting plate 11. Then, rotate the base frame rod 2 upward so that it approaches the already rotated connecting plate 3. Place the seat frame rod 4 on the base frame rod 2, and the two ends of the base frame rod 2 are engaged in the second slot 62 of the fixing plate 6. A fixing rope 221 is set through the mounting cylinder 22 to further fix the base frame rod 2, the connecting plate 3 and the side frame rod 1 together to prevent the frame from moving or deforming unnecessarily during storage or transportation.
