Such design makes the cushion can wrap up the frame firmly.

As shown in fig. 4 and 6, the upper frame 11 below the right end point of the shock absorbing part is hinged to the transmission set 224 of the first link 221. The right end of the seat cushion 5 is a seating portion 54, and the upper frame 11 below the right end of the seating portion 54 is hinged to an upper pivot boss 211 of the elastic portion 21. And the sitting portion 54 is designed into an arc shape, the curve of the sitting portion is gradually vertical to the direction of the front frame 7, and the sitting portion 54 can be stably seated on the sitting portion without sliding forwards.

During the use, first connecting rod 221 drives frame 11 left end upward movement makes the pars contractilis upswing, the person of taking sits in the portion of taking 54, the jolt that receives is littleer, the vibrations that feel promptly reduce, and have certain radian behind the pars contractilis upshockey, make the person of taking stably sit in the portion of taking 54 with the radian of the portion of taking 54 right-hand member jointly, 5 cup joint on frame 11 on half enclosure ground of cushion, the use of panel has been reduced, the cost is reduced has alleviateed electronic scooter's weight, and the curved design of cushion 5 both sides arc can give other people better taking experience.

Fig. 7 is a schematic view of the upper frame according to the first embodiment, and as shown in fig. 4 and 7, the upper frame 11 is in a zigzag shape as a whole, and includes a wrapping portion 114 and a connecting portion 113. The wrapping part 114 and the connecting part 113 are integrally formed, the cushion 5 is sleeved on the wrapping part 114, and the right end of the connecting part 113 is connected with the transmission mechanism 8.

The connecting sheet group 111 and the connecting sheet group 112 are arranged below the bottom end of the wrapping portion 114, the connecting sheet group 111 is hinged to the first connecting rod 221 transmission group 224, the connecting sheet group 112 is hinged to the upper rotating shaft sleeve 211 of the elastic portion 21, and the interval between the connecting sheet group 111 and the connecting sheet group 112 corresponds to the sitting portion 54 on the seat cushion 5, so that the shock absorption mechanism 2 formed by the connecting rod portion 22 and the spring portion acts on the sitting portion 54, and the shock received by the sitting portion 54 is reduced.

Working principle when using the utility model provides an electric scooter, the user sits at first on cushion 5 takes advantage of seat 54 to make the upper frame 11 under cushion 5 move down, and then makes the drive group 223 of first connecting rod 221 rotate to elastic part 21 around the pin joint of first connecting rod 221 with second connecting rod 222, finally promotes adjusting connecting rod 216 and moves to fixed connecting rod 215 and compress damping spring 217, makes elastic part 21 itself have great elastic coefficient like this, has improved the ability of buffering vibrations.

When the electric scooter runs on a road with uneven road, the rear wheel 3 bumps, the rear wheel lower suspension 13 is hinged with the pedal plate 4, the rear wheel lower suspension 13 moves upwards around the hinged point of the rear wheel lower suspension 13 and the pedal plate 4, the rear wheel upper suspension 12 and the rear wheel lower suspension 13 are both fixedly connected with the suspension connecting piece 14, and at the moment, the rear wheel upper suspension 12 moves towards the extending direction. The second link 222 is connected to the rear wheel upper suspension 12, so that when the rear wheel upper suspension 12 is driven, the driving portion 223 of the first link 221 swings toward the elastic portion 21 around the hinge point of the second link 222 and the first link 221, so that the lower rotating sleeve 212 is pressed in the extending direction thereof, the adjusting link 216 is compressed toward the fixed link 215, and the damper spring 217 is compressed to damp the vibration transmitted from the rear wheel. When the vibration is transmitted to the top end of the elastic portion 21, the upper rotating shaft cover 211 is hinged to the upper frame 11, and the elastic portion 21 swings around the hinge point, so that the cushion 5 is not bumpy.

When the residual vibration is not buffered by the elastic portion 21, the transmission set 224 is hinged to the rear connecting plate set 111, the residual vibration drives the transmission set 224 to swing downward around the hinged point, so that the damping portion 53 of the seat cushion 5 moves downward, the sitting portion 54 sinks downward when a user sits on the seat cushion, the cushion 5 is still stable due to the downward vibration of the damping portion 53 during the vibration, the vibration occurs in the damping portion 53, and the user feels less jolt on the sitting portion 54, which is equivalent to reducing the vibration.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
