The retractable rear seat 3 is slidably connected to the extension seat 2, the top of the extension seat 2 is hinged with a support frame 10, and a seat 8 is rotatably installed on the top of the support frame 10. A connecting beam 11 is hinged on one side of the seat 8, and the connecting beam 11 is hinged to the middle part of the front shell 6 of the vehicle. A traction beam 23 is hinged on the top of the retractable rear seat 3, and one end of the traction beam 23 is hinged to the middle part of the support frame 10. An auxiliary roller 17 is installed on the side of the bottom end of the vehicle body 1 away from the extension seat 2, and the auxiliary roller 17 is located between the two front wheels 4;

[0018] In this embodiment, during use, the turning handle 7 can be turned to drive the rotating rod 19 to rotate. When the rotating rod 19 rotates to the left, the left-side contact copper sheet 21 on the surface of the rotating rod 19 contacts the left-side contact switch 20 inside the front shell 6, so that the circuit is connected, so that the right-wheel motor 16 at the bottom of the vehicle body 1 works, and the right-wheel motor 16 drives the right front wheel 4 to rotate, so that the vehicle body 1 can turn left. Similarly, when the rotating rod 19 rotates to the right, the right-side contact copper sheet 21 on the surface of the rotating rod 19 contacts the right-side contact switch 20 inside the front shell 6, so that the circuit is connected, so that the left-wheel motor 15 at the bottom of the vehicle body 1 works, and the left-wheel motor 15 drives the left front wheel 4 to rotate, so that the vehicle body 1 can turn right.

[0019] See also Figure 1-5 A left pedal 5 is provided on one side of the top of the vehicle body 1, and a battery 22 is installed inside the left pedal 5. A right pedal 13 is provided on the other side of the top of the vehicle body 1, and a throttle switch 14 is provided on the top of the right pedal 13. A left wheel motor 15 and a right wheel motor 16 are both electrically connected to the throttle switch 14.

[0021] See also Figure 1-6 A movable slide 12 is provided in the middle of the expansion seat 2, and the retracted rear seat 3 is slidably connected to the inside of the movable slide 12, and one end of the return spring 27 away from the transverse iron sheet 24 is connected to the surface of the inner wall of the retracted rear seat 3, and a plurality of limit grooves matching and engaging with the limit clamping column 25 are provided at the bottom of the expansion seat 2;

[0022] In this embodiment, the contraction pressing block 18 is triggered to move backward, and the contraction pressing block 18 pulls the transverse iron sheet 24 to move. When the transverse iron sheet 24 moves, the bottom of the limit clamping column 25 will slide to the position of the curved head 26, and then the limit clamping column 25 will drop. When the limit clamping column 25 moves down, the top moves out of the limit groove inside the expansion seat 2, and then after no longer limiting, the contraction rear seat 3 can be directly pulled to move backward. The contraction rear seat 3 slides inside the moving slide 12 of the expansion seat 2. At the same time, the contraction rear seat 3 will pull the traction beam 23 to move, and the traction beam 23 pulls the connecting beam 11 to move backward. The seat 8 will move backward, and the support frame 10 will pull the connecting beam 11 to move, and the connecting beam 11 will cause the front shell 6 to tilt backward. The seat 8 will move to the tail position of the expansion seat 2, completing the extension of the trolley. Similarly, pushing the retracted rear seat 3 forward in the opposite direction can complete the retraction of the trolley, and when the retraction pressing block 18 is sent away, the retraction pressing block 18 will be reset under the action of the reset spring 27 to push the transverse iron sheet 24 to move, so that the limit clamping column 25 slides back to the top position of the transverse iron sheet 24, and then the limit clamping column 25 moves upward and is inserted into the limit groove inside the expansion seat 2 to complete the limiting work.

[0023] When used specifically, the electric bicycle for children with a telescopic mechanism of the utility model can drive the rotating rod 19 to rotate by turning the turning handle 7 during use. When the rotating rod 19 rotates to the left, the left-side contact copper sheet 21 on the surface of the rotating rod 19 contacts the left-side contact switch 20 inside the front shell 6 of the vehicle, so that the circuit is connected, so that the right-wheel motor 16 at the bottom of the vehicle body 1 works, and the right-wheel motor 16 drives the right-side front wheel 4 to rotate, so that the vehicle body 1 can turn to the left. Similarly, when the rotating rod 19 rotates to the right, the right-side contact copper sheet 21 on the surface of the rotating rod 19 contacts the right-side contact switch 20 inside the front shell 6 of the vehicle, so that the circuit is connected, so that the left-side wheel at the bottom of the vehicle body 1 The motor 15 works, and the left-wheel motor 15 drives the left front wheel 4 to rotate, so that the vehicle body 1 can turn right. When the turning handle 7 is in the middle and does not rotate, stepping on the throttle switch 14 on the right pedal 13 can make the left-wheel motor 15 and the right-wheel motor 16 work at the same time, and the front wheel 4 rotates to make the vehicle body 1 move forward. The entire trolley is operated by turning the handle left and right, which is more convenient to control. In addition, the trolley can be retracted as needed, that is, the seat 8 can be retracted to the middle of the expansion seat 2 or the seat 8 can be extended to the tail of the expansion seat 2, specifically by pressing the retracting pressing block 18 to move backward, and the retracting pressing block 18 pulls the transverse iron sheet 24 to move , while the transverse iron sheet 24 moves, the bottom of the limit column 25 will slide to the position of the curved head 26, and then the limit column 25 will drop. When the limit column 25 moves down, the top moves out of the limit groove inside the expansion seat 2, and then after no longer limiting, the retracted rear seat 3 can be directly pulled to move backward. The retracted rear seat 3 slides inside the moving slideway 12 of the expansion seat 2. At the same time, the retracted rear seat 3 will pull the traction beam 23 to move, and the traction beam 23 pulls the connecting beam 11 to move backward, so that the seat 8 will move backward, and the support frame 10 will pull the connecting beam 11 to move, and the connecting beam 11 makes the front shell 6 of the vehicle also tilt backward, and the seat 8 moves to the expansion seat 2. The rear position of the expansion seat 2 is used to complete the extension of the car. Similarly, when the retracted rear seat 3 is pushed forward in the opposite direction, the retracted rear seat 3 will indirectly push the support frame 10, the seat 8 and the front shell 6 to move forward, so that the seat 8 is in the middle position of the expansion seat 2, and the retraction of the car is completed. The whole car adopts a retractable manner, which increases the play method of the car. When the car is retracted, it can be suitable for younger children to play, and the car can be used as an indoor car. When the car is extended, it is suitable for some older children to play, and can be used as a kart drift car.
