[0002] An electric-assisted bicycle is a bicycle equipped with an electric motor that can provide additional electric assistance when riding. This type of bicycle is usually equipped with a battery and a controller. It monitors the rider's pedaling force through sensors and automatically provides different degrees of electric assistance according to demand. Using the electric-assisted function can help riders easily cope with slopes or long-distance riding and reduce physical exertion. The pedals of an electric-assisted bicycle refer to the part installed on the bicycle for stepping on when riding. The pedals of an electric-assisted bicycle are similar to the pedals of an ordinary bicycle. Their main function is to allow the rider to propel the bicycle forward by pedaling. In an electric-assisted bicycle, the pedals still play the same role, but riding is easier with the help of the power system.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a foldable pedal for an electric power-assisted bicycle, comprising a pedal 1, a fixing plate 3 and a fixing frame 8. Two connecting plates 2 are symmetrically welded on the side of the fixing plate 3. A connecting rod 12 is installed on the opposite side of the two connecting plates 2. A fixing sleeve 7 is movably installed on the connecting rod 12. A distance is left between the fixing sleeve 7 and the side of the fixing plate 3. When the fixing sleeve 7 rotates on the connecting rod 12, it will not interfere with the fixing plate 3. A pedal 1 is installed on the outside of the fixing sleeve 7. A limiting frame 13 is installed on the side of the fixing plate 3 below the fixing sleeve 7. After the fixing sleeve 7 drives the pedal 1 to rotate to a suitable stepping position, the bottom of the pedal 1 contacts the top of the limiting frame 13. The limiting frame 13 provides support force for the pedal 1 to limit the rotation range of the pedal 1. Anti-skid strips 9 are installed on the top of the pedal 1 in a straight line and equidistantly. The anti-skid strips 9 increase the friction between the sole and the foot, and increase the stability when stepping on the pedal 1. A screw groove 15 is provided on the front side, and a screw rod 11 is installed at the bottom of the fixing frame 8. The screw rod 11 is meshed and connected with the screw groove 15 of the pedal 1. By rotating the screw rod 11, the screw rod 11 rotates and moves in the screw groove 15 of the pedal 1, and the position between the fixing frame 8 and the pedal 1 can be adjusted. A magnetic block 16 is installed on the side of the fixing plate 3 above the fixing sleeve 7, and a magnetic block 2 10 is installed on the top of the pedal 1. The magnetic block 2 10 and the magnetic block 1 6 are attracted to each other by opposite sexes. When the pedal 1 is folded, the pedal 1 is rotated upward. After the pedal 1 is rotated to a suitable position, the magnetic block 1 6 attracts the magnetic block 2 10 to fix the position of the pedal 1. A bearing 14 is installed on the side of the fixing plate 3 away from the fixing sleeve 7, and a fixing disk 4 is fixedly installed on the inner ring of the bearing 14. A stud 5 is installed on the side of the fixing disk 4 away from the fixing plate 3, and the stud 5 is perpendicular to the fixing plate 3. The stud 5 can be rotated using the fixing disk 4 to fix the stud 5 on the frame of the electric power-assisted bicycle.

[0022] Working principle: Use the fixed disk 4 to rotate the stud 5, and screw the stud 5 into the screw hole reserved on the electric power-assisted bicycle frame. When using the pedal 1, the fixed sleeve 7 rotates downward on the connecting rod 12. After the fixed sleeve 7 drives the pedal 1 to rotate to a suitable stepping position, the bottom of the pedal 1 contacts the top of the limit frame 13. The limit frame 13 provides support for the pedal 1. The rider steps on the pedal 1 to drive the chain disc of the electric power-assisted bicycle to rotate, and rotates the screw 11. The screw 11 rotates and moves in the screw groove 15 of the pedal 1. The screw 11 drives the fixed frame 8 to move. According to the length of the foot, after moving the fixed frame 8 to a suitable position, insert the toe of the shoe into the fixed frame 8 to increase the stability when stepping on the pedal 1. When folding the pedal 1, rotate the pedal 1 upward. After the pedal 1 rotates to a suitable position, the magnetic block 1 6 attracts the magnetic block 2 10 to fix the position of the pedal 1.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
