Support rods are embedded inside the upper two ends of the secondary seat cushion. A shaft passes through the end of the support rod away from the secondary seat cushion. A fixing block is installed below the shaft, and a torsion spring is wound around the outer periphery of the shaft.

[0007] Preferably, the fixing rod is fixedly connected to the vehicle frame, and the fixing rod has multiple holes corresponding to the size of the screw.

[0008] Preferably, the tripod is slidably connected to the fixed rod, the tripod has holes corresponding to the size of the screw, and the two ends of the shock absorber are fixedly connected to the tripod and the seat cushion block, respectively.

[0009] Preferably, the side of the seat cushion block is in close contact with the outer surface of the tripod, and the sub-seat cushion is rotatably connected to the seat cushion block via a hinge.

[0010] Preferably, the secondary seat cushion has a groove corresponding to the size of the support rod, the support rod is rotatably connected to the shaft, and the fixing block is fixedly connected to the shaft.

[0011] Preferably, the fixing block is fixedly connected to the seat cushion block, and the two ends of the torsion spring are fixedly connected to the fixing block and the support rod, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When using this utility model electric bicycle, the screw can be loosened and pulled out first, and the position of the tripod can be adjusted by sliding it along the fixing rod. Then, the screw can be passed through the hole between the tripod and the fixing rod to facilitate the adjustment of the position of the tripod. The shock absorber plays a role in energy dissipation and vibration reduction, which can adapt to different riders.

[0013] This utility model electric bicycle, through the setting of the extension component, allows the support rod to rotate outward around the axle. Then, the secondary seat is rotated parallel to the seat block via the hinge.

[0018] Includes: adjustment component 01, with extension component 02 installed on one side above the adjustment component 01; The adjustment assembly 01 includes a frame 11. A fixing rod 12 is installed in the middle of the upper side of one side of the frame 11. Triangle brackets 13 are set on both sides of the fixing rod 12. Screws 14 pass through the interior of the triangle brackets 13 and the fixing rod 12. The screws 14 can pass through the holes of the fixing rod 12 and the triangle brackets 13 to fix the position of the triangle brackets 13. Shock absorbers 15 are installed on the upper two sides of the triangle brackets 13. The shock absorbers 15 play the role of energy dissipation and vibration reduction to adapt to different riders. A saddle block 16 is set above the shock absorber 15. The side of the saddle block 16 plays a guiding role.

[0019] Furthermore, the extension component 02 includes a secondary seat cushion 21. One side of the secondary seat cushion 21 is connected to the seat cushion block 16 via a hinge 22. Support rods 23 are embedded in the upper two ends of the secondary seat cushion 21. The support rods 23 can rotate around the secondary seat cushion 21 and enter the groove of the secondary seat cushion 21 to limit the position of the secondary seat cushion 21. A shaft 24 passes through the end of the support rod 23 away from the secondary seat cushion 21. A fixing block 25 is installed below the shaft 24. A torsion spring 26 is wound around the outer periphery of the shaft 24. The torsion spring 26 provides elastic force. Under the action of the elastic force of the torsion spring 26, the support rod 23 rotates back to the underside of the secondary seat cushion 21 around the shaft 24 to support the secondary seat cushion 21.

[0020] Furthermore, the fixing rod 12 is fixedly connected to the frame 11 to ensure the stability of the fixing rod 12. The fixing rod 12 has multiple holes corresponding to the size of the screw 14, through which the screw 14 can be passed to fix the position of the tripod 13.

[0021] Furthermore, the tripod 13 is slidably connected to the fixing rod 12. The tripod 13 has holes corresponding to the size of the screw 14, through which the screw 14 can be passed to fix the position of the tripod 13. The two ends of the shock absorber 15 are fixedly connected to the tripod 13 and the seat block 16 respectively. The shock absorber 15 plays the role of energy dissipation and vibration reduction, adapting to different riders.

[0022] Furthermore, the side of the seat cushion 16 is in close contact with the outer surface of the tripod 13, and the side of the seat cushion 16 plays a guiding role. The sub-seat cushion 21 is rotatably connected to the seat cushion 16 through the hinge 22.

[0023] Furthermore, the secondary seat cushion 21 has a groove corresponding to the size of the support rod 23. The support rod 23 can rotate around the secondary seat cushion 21 and enter the groove of the secondary seat cushion 21 to limit the position of the secondary seat cushion 21. The support rod 23 is rotatably connected to the shaft 24, and the fixing block 25 is fixedly connected to the shaft 24 to ensure the stability of the position of the shaft 24.
