Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a folding electric bicycle, including a body 1, a storage mechanism 7 is provided at the top of the inner cavity of the body 1, an adjustable handlebar 2 is provided on one side of the body 1, a seat 4 and a control screen 10 are provided on the upper surface of the body 1, a reinforcing tube 8 and a reinforcing beam 9 are arranged sequentially from top to bottom in the inner cavity of the body 1, and auxiliary wheels 3 are provided at the lower ends of both sides of the body 1 adjacent to the adjustable handlebar 2.

[0023] The storage mechanism 7 includes a lifting assembly 71 installed on the top of the inner cavity of the vehicle body 1. An extension assembly 73 is provided at the lower end of the lifting assembly 71. A drive assembly 72 is installed on the extension assembly 73. Multiple sets of stabilizing sleeve rods 74 are provided on the extension assembly 73. The upper ends of the multiple sets of stabilizing sleeve rods 74 are fixedly connected to the top of the inner cavity of the vehicle body 1. A guide rail 714 for sliding two sets of sliding seats 713 is provided on the top of the inner cavity of the vehicle body 1.

[0024] The lifting assembly 71 includes a dual-axis motor 711, two sets of slides 713, and two sets of fixed seats 716. The lower ends of the two sets of slides 713 are rotatably connected to support rods 715. The upper ends of the two sets of fixed seats 716 are rotatably connected to the lower ends of the two sets of support rods 715, respectively. The two output ends of the dual-axis motor 711 are driven by adjusting screws 712. The two sets of slides 713 are respectively set at both ends of the two sets of adjusting screws 712. The position of the slides 713 is adjusted by driving the adjusting screws 712 through the dual-axis motor 711. By changing the tilt angle of the support rods 715, the height of the extension assembly 73 can be easily adjusted, thereby facilitating the contact of the front wheel assembly 6 and the rear wheel assembly 5 with the ground and improving the efficiency of the deployment of the front wheel assembly 6 and the rear wheel assembly 5.

[0025] The extension assembly 73 includes a mounting plate 731 disposed at the lower end of multiple sets of stabilizing sleeve rods 74, a drive assembly 72 disposed on the upper surface of the mounting plate 731, and a bidirectional screw 732 rotatably disposed below the mounting plate 731. A gear 734 meshing with the drive assembly 72 is disposed in the middle of the bidirectional screw 732. The drive assembly 72 includes a drive motor and a drive gear. The drive motor drives the drive gear to mesh with the gear 734 on the bidirectional screw 732, thereby facilitating the adjustment of the distance between the front wheel assembly 6 and the rear wheel assembly 5.

[0026] Two sets of guide rods 733 are fixedly connected to the lower surface of the mounting plate 731. Both sets of guide rods 733 are arranged parallel to the bidirectional screw 732. Both sets of guide rods 733 and the bidirectional screw 732 are set on the same plane. The guide rods 733 improve the stability of the front wheel assembly 6 and the rear wheel assembly 5 when they move, thereby improving the overall service life of the electric bicycle.

[0027] The adjustable handlebar 2 includes a mounting base 21 installed on one side of the vehicle body 1. A telescopic handlebar 22 is provided at the upper end of the mounting base 21, and a connecting shaft 23 is provided at the lower end of the mounting base 21. The connecting shaft 23 is slidably inserted into the lower end of the telescopic handlebar 22. The height of the telescopic handlebar 22 is adjustable, making it convenient for people of different heights to use. At the same time, the connecting shaft 23 can be easily stored at the lower end of the telescopic handlebar 22, reducing the space occupied when storing it.

[0028] A folding wheel structure for an electric bicycle, installed on a folding electric bicycle as described above, also includes a front wheel assembly 6 and a rear wheel assembly 5. The front wheel assembly 6 is slidably disposed at one end of the lower surface of the mounting plate 731, and the rear wheel assembly 5 is slidably disposed at the other end of the lower surface of the mounting plate 731. The front wheel assembly 6 and the rear wheel assembly 5 can quickly switch between a folded state and a riding state through a storage mechanism 7. The automation level is high, saving manual operation steps during the transition between the folded state and the riding state.

[0029] The front wheel assembly 6 includes a front connecting plate 61 that is threadedly connected to the bidirectional screw 732. Two sets of telescopic sleeves 62 are rotatably mounted on the lower surface of the front connecting plate 61, and a front wheel 63 is rotatably mounted on one end of each set of telescopic sleeves 62. A base (not shown in the figure) is provided on the front wheel 63 to dock with the connecting shaft 23, and an electromagnet is provided on the base, which can quickly and magnetically connect with the connecting shaft 23, thereby improving the docking efficiency between the adjustable handlebar 2 and the front wheel assembly 6.

[0030] The rear wheel assembly 5 includes a rear connecting plate 51 threadedly connected to a bidirectional screw 732, and a rear wheel 52 is mounted on the lower surface of the rear connecting plate 51.

[0031] In use, the dual-axis motor 711 and drive assembly 72 are started synchronously by the control panel 10. The dual-axis motor 711 drives the adjusting screw 712 to adjust the position of the slide 713. The slide 713 slides along the guide rail 714 and moves closer together, thereby increasing the inclination angle of the support rod 715, which further drives the extension assembly 73 to descend, thereby extending the front wheel assembly 6 and the rear wheel assembly 5 out of the vehicle body 1. At the same time, the stability of the descent of the extension assembly 73 is ensured by the action of multiple sets of stabilizing sleeves 74. The drive assembly 72 drives the gear 734 to rotate, thereby driving the bidirectional screw 732 to move the front wheel assembly 6 and the rear wheel assembly 5 away from each other, increasing the distance between the front wheel assembly 6 and the rear wheel assembly 5, improving the stability of the support for the vehicle body 1, and thus improving the stability of the electric bicycle when riding. The unfolding and retraction process of the front wheel assembly 6 and the rear wheel assembly 5 is quick, reducing manual operation steps and thus improving the convenience of use.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
