They have become a trusted means of transportation. Folding electric bicycles have become a common type of electric bicycle due to their ease of use and portability.

[0003] Existing electric bicycle folding mechanisms mostly employ a single-dimensional locking method, such as securing with bolts or clips alone. This design is prone to loosening over long-term use, making the folding mechanism susceptible to loosening or unlocking due to vibration or impact during riding. This reduces the stability of the frame connection and compromises riding safety. Therefore, we need to propose a multi-dimensional self-locking mechanism for the folding frame of electric bicycles to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A multi-dimensional self-locking mechanism for a foldable frame of an electric bicycle.

[0026] The device includes a first buckle plate 110 and a second buckle plate 120. A frame tube 130 is installed on the opposite side of the first buckle plate 110 and the second buckle plate 120. The opposite sides of the first buckle plate 110 and the second buckle plate 120 are rotatably connected. A first locking component for fixing the first buckle plate 110 and the second buckle plate 120 is installed on the first buckle plate 110. A second locking component for limiting the first locking component is installed on the first locking component. A fixing component for fixing the second locking component is installed on the first locking component.

[0027] By setting up the first locking component, the second locking component, and the fixing component, the frame achieves multi-dimensional self-locking, making the frame less prone to loosening after long-term use. At the same time, it avoids the folding mechanism of the electric bicycle from unlocking due to vibration or accidents during riding, thus improving the stability of the frame connection and the safety of use.

[0028] A first fixing plate 140 is installed on one side of both the first buckle plate 110 and the second buckle plate 120, and a second fixing plate 150 is installed on both sets of the first fixing plates 140.

[0029] By setting the first fixing plate 140 and the second fixing plate 150, the overall rigidity of the frame is enhanced, ensuring the precise positioning of each component during the unfolding process, and further improving the stability and service life of the frame.

[0030] Two sets of rotating cylinders 160 are installed on the other side of the first buckle plate 110, and a rotating column 170 is installed on the other side of the second buckle plate 120. The rotating column 170 is rotatably connected to the two sets of rotating cylinders 160.

[0031] The first buckle plate 110 and the second buckle plate 120 are connected by the rotating cylinder 160 and the rotating column 170 to form a stable support structure. Furthermore, the frame can be folded at multiple angles by the relative rotation of the rotating cylinder 160 and the rotating column 170, which enhances the flexibility and portability of the frame.

[0032] The first locking component includes a first limiting plate 210, which is rotatably connected to the first buckle plate 110. The first limiting plate 210 has a first limiting groove 211 and a second limiting groove 212, which are used in conjunction with the first fixing plate 140 and the second fixing plate 150, respectively.

[0033] The first limiting groove 211 of the first limiting plate 210 precisely fits with the two sets of first fixing plates 140, thereby limiting the two sets of first fixing plates 140, connecting the first buckle plate 110 and the second buckle plate 120, fixing the frame and ensuring the stability of the frame.

[0034] The first locking component further includes a first mounting base 220, which is mounted on the first buckle plate 110. A first rotating block 230 is rotatably connected to the first mounting base 220, and the first rotating block 230 is mounted on the first limiting plate 210.

[0035] The first limiting plate 210, through the rotation of the first rotating block 230, precisely adjusts the position of the first limiting plate 210, further optimizes the limiting effect, ensures that the frame remains stable during the unfolding process, and improves the reliability and durability of the overall structure.

[0036] The second locking component includes a second limiting plate 310, which is rotatably connected to a first limiting plate 210. A third limiting groove 311 is provided on the second limiting plate 310, and the third limiting groove 311 is used in conjunction with the second fixing plate 150.

[0037] The second limiting groove 212 and the second fixing plate 150 are precisely matched to further lock the structure, prevent accidental unlocking, and improve overall safety.

[0038] The second locking component also includes a second mounting base 320, which is mounted on the first limiting plate 210. A second rotating block 330 is mounted on the second mounting base 320 and is mounted on the second limiting plate 310.

[0039] The second limiting plate 310, through the adjustment of the second rotating block 330, precisely controls the position of the second limiting plate 310, enhances locking stability, ensures that the frame remains safe and stable under any usage conditions, and further extends its service life.

[0040] The fixing component includes an adjustment groove 410, which is formed within the first limiting plate 210. An adjustment plate 420 is slidably connected within the adjustment groove 410. Multiple sets of springs 430 are installed on one side of the adjustment plate 420, with one end of each set of springs 430 mounted on the inner wall of the adjustment groove 410. A locking block 440 is installed on one end of the adjustment plate 420.

[0041] The locking block 440 automatically engages with the slot 450 through the action of the spring 430, fixing the second limiting plate 310 so that the second limiting plate 310 is not easy to fall off, ensuring that the frame is securely locked.

[0042] The bottom of one end of the second limiting plate 310 is provided with a slot 450, which is used in conjunction with the block 440 on the adjusting plate 420.

[0043] The locking block 440, secured by the spring force of the spring 430, is firmly embedded in the slot 450, effectively preventing displacement of the second limiting plate 310. This further enhances the overall stability and safety of the frame, ensuring excellent locking performance under various usage conditions. Furthermore, one side of the locking block 440 is beveled, facilitating its smooth entry into the slot 450 during the fixing of the second limiting plate 310. The beveled design reduces friction, improves operational convenience, ensures a smooth and error-free locking process, and further optimizes the user experience.

[0044] In use, by rotating the first limiting plate 210, the first limiting groove 211 of the first limiting plate 210 precisely engages with the two sets of first fixing plates 140, thus limiting the two sets of first fixing plates 140 and connecting the first buckle plate 110 and the second buckle plate 120 to fix the frame and ensure its stability. Both sets of second fixing plates 150 are located within the second limiting groove 212. Then, by rotating the second limiting plate 310, the third limiting groove 311 of the second limiting plate 310 precisely engages with the second fixing plate 150, thus limiting the second fixing plate 150 and ensuring the frame remains stable during use at multiple angles. The adjusting plate 420 is automatically adjusted by the spring 430, and the locking block 440 is precisely embedded in the locking slot 450, further reinforcing the structure and improving overall safety. Through this series of precise adjustments, the frame remains stable at any angle, avoiding swaying and displacement during use, greatly improving the user experience and safety. Whether for everyday riding or on challenging road conditions, the frame ensures stability and durability, providing users with a worry-free riding experience.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
