[0008] The technical solution adopted by the present application to solve the above technical problem is:

[0009] An electric scooter with a suspension structure includes a frame and a rear fork arm, and the frame and the rear fork arm are connected by a rotating shaft mechanism, so that the rear fork arm can surround the rotating shaft mechanism Rotating, a buffer mechanism is fixed on the frame, and the buffer mechanism is fixedly connected to the rear fork arm.

[0010] According to an embodiment of the present application, the hinge mechanism includes a suspension connection bracket, and the suspension connection bracket is fixed to an outer end of the frame by a bolt, and the suspension connection bracket is provided with a bolt hole. The rear fork arm is movably connected to the suspension connecting frame through a bolt rotating shaft.

[0011] According to an embodiment of the present application, the buffer mechanism includes at least one suspension rod, a spring corresponding to the number of the suspension rods, and a limiting plate, and the limiting plate is provided with the suspension rod a corresponding number of through holes, the limiting plate is fixed on the frame, the tail end of the suspension rod is sleeved with the spring and then passes through the through hole, and then the nut is threaded, and the shock rod is The head end is fixedly connected to the rear fork arm by bolts.

[0012] According to an embodiment of the present application, the number of the suspension bars is set to two.

[0013] According to an embodiment of the present application, the rear fork arm connects the tire of the vehicle through a rotating shaft. \¥0 2019/149024 卩(:1' 2019/070225

[0014] The technical solution of the present application has the following beneficial effects: The present application realizes the flexible connection between the frame and the rear fork arm, and can effectively alleviate the mutual impact between the frame and the rear fork arm; the buffer component of the present application adopts a double spring Structure, with better mechanical balance; The application is simple in structure and convenient to maintain.

Figure 5 is an eight-eighth view of Figure 4;

[0022] FIG. 6 is an 8-:8-direction view of FIG. 4.

DETAILED DESCRIPTION

[0024] As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the electric scooter with a suspension structure of the present application, an electric scooter with a suspension structure, including the frame 3 The rear fork arm 1, the frame 3 and the rear fork arm 1 are connected by a rotating shaft mechanism, so that the rear fork arm 1 can be rotated around the rotating shaft mechanism, a buffer mechanism is fixed on the frame 3, and the buffer mechanism is fixedly connected with the rear fork arm 1. According to an embodiment of the present application, the hinge mechanism includes a suspension connection bracket 8 , and the suspension connection bracket 8 is fixed to the outer end of the frame 3 by bolts 11 , and the suspension connection bracket 8 is provided with a bolt hole, and the rear fork arm 1 passes the bolt The rotating shaft 5 is movably connected to the suspension connecting frame 8. The buffer mechanism includes at least one suspension rod 7, a spring 4 corresponding to the number of the suspension rods 7, and a limiting plate 2. The limiting plate 2 is provided with a through hole corresponding to the number of the suspension rods 7, and the limiting plate 2 is fixed at On the frame 3, the tail end of the suspension rod 7 is sleeved with the spring 4, passes through the through hole, and then the nut 10 is screwed. The head end of the suspension rod 7 is fixedly connected to the rear fork arm 1 by bolts 6. According to the embodiment of the present application, the number of the suspension bars 7 is set to two. The rear fork arm 1 connects the tires 9 through the shaft.

[0025] The frame 3 and the suspension connecting frame 8 are fixed by bolts 11, and the suspension connecting frame 8 and the rear fork arm 1 are connected by pins formed by bolts 5 to realize rotation. The suspension rod 7 is locked by the nut 10 through the spring 4 and the limiting plate 2, and the spring 4 is compressed by a certain amount, and then connected to the rear fork arm 1 by the bolt 6 to form a pin, \¥0 2019/149024 卩(:1' 2019/070225 is placed on the frame 3, the limit plate 2 is placed at the step of the frame to prevent forward movement. When the frame 3 is stressed, the frame 3 will be lowered. Shifting, thereby transmitting the force to the rear fork arm 1 and the tire 9 of the vehicle, the rear fork arm 1 and the tire 9 of the vehicle are rotated clockwise around the bolt 5, thereby moving the suspension rod 7 forward, since the suspension rod 7 is subjected to the spring 4 The elastic force will prevent the suspension rod 7 from moving forward, thereby preventing the frame 3 from moving down, thereby reducing the amplitude of the vibration on the bumpy road surface, allowing the electric scooter to move smoothly and making the rider feel comfortable.

A person skilled in the art can implement the present application in various embodiments without departing from the spirit and spirit of the present application. The above is only a preferred embodiment of the present application, and is not intended to limit the scope of the application. The equivalent structural changes made in the specification and the drawings of the present application are included in the scope of the claims.
