[0030] The above-mentioned external electric scooter shock absorbing device, under the cooperation of the first shock absorbing member 4 and the second shock absorbing member 5, performs double shock absorption, improves the shock absorption effect and improves the driving comfort. At the same time, the first shock absorbing member 4 and the second shock absorbing member 5 are both arranged externally, which is convenient for maintenance and replacement; furthermore, the wheel member 6 transmits the vibration force to the first shock absorbing frame 2 and the second shock absorbing frame 3, so that the first shock absorbing frame 2 and the second shock absorbing frame 3 are respectively swung relative to the frame member 1, which is convenient for transmitting the vibration force to the first shock absorbing member 4 and the second shock absorbing member 5, ensuring the timeliness of shock absorption and the shock absorption effect; furthermore, the travel of the first shock absorbing member 4 and the second shock absorbing member 5 is less limited, so that the travel of the first shock absorbing member 4 and the second shock absorbing member 5 is longer, the shock absorption effect is more moderate, and the shock absorption effect is better.

[0031] The first shock-absorbing member 4 and the second shock-absorbing member 5 are used to suppress the shock caused by the rebound of the spring after shock absorption and the impact from the road surface, so as to achieve a shock-absorbing effect.

[0032] The first shock-absorbing frame 2 includes a first frame rod 21 and a first frame arm 22. The lower portion of the first frame rod 21 is assembled with the wheel member 6, and the upper portion of the first frame rod 21 is docked with the inner end of the first frame arm 22. The first frame rod 21 is arranged to extend upwardly and obliquely, and the first frame arm 22 is arranged to extend downwardly and obliquely, and the outer end of the first frame arm 22 forms a first frame portion.

[0033] In this way, since the first arm 22 is arranged to extend downwardly and tilted, the first arm 22 can easily transmit the impact force of the road surface to the first shock-absorbing component 4, thereby ensuring the shock-absorbing effect; furthermore, since the first rod 21 is extended upwardly and tilted, it is convenient for the first rod 21 and the first arm 22 to be assembled together, and at the same time, it is convenient for the wheel component 6 to transmit the impact force of the road surface to the first rod 21 and then to the first arm 22, and finally to the first shock-absorbing component 4, thereby ensuring the shock-absorbing effect.

The first fork segment 121 is arranged in an arc shape, and the lower part of the first fork segment 121 forms a first support portion.

[0035] In this way, since the first fork segment 121 is arranged in an arc shape, the bearing capacity of the first fork segment 121 is improved, and the service life of the first fork segment 121 is improved; at the same time, the first fork 12 and the first frame rod 21 are hingedly arranged, when the first frame rod 21 is affected by the impact force of the road surface and swings relative to the first fork 12, the impact force of the road surface is transmitted to the first shock absorber 4, thereby realizing the shock absorbing effect.

[0038] The first frame arm 22 includes two first arm pieces 221 and a fastener 222. The inner ends of the two first arm pieces 221 clamp the first frame rod 21, and the outer ends of the two first arm pieces 221 form a first frame portion; the fastener 222 synchronously penetrates the two first arm pieces 221 and the first frame rod 21, and the rotation of the fastener 222 is used to fix the two first arm pieces 221 and the first frame rod 21 in a fixed state or an unlocked state.

[0039] Under the action of the first arm piece 221, the assembly stability of the first frame arm 22 and the first frame rod 21 is improved, and the two first arm pieces 221 and the first frame rod 21 are fixed or unlocked by the fastener 222.

[0040] Along the direction toward the first shock absorber 4, the cross-sectional area of ​​the first arm piece 221 is arranged to gradually decrease, so that it is convenient to transmit the impact force or vibration force along the direction of the first shock absorber 4. At the same time, the relative shaking of the first arm piece 221 is reduced, the transmission stability of the impact force or vibration force is improved, and it helps to improve the concentration of the impact force or vibration force transmission direction, so as to facilitate the transmission of the impact force or vibration force along the direction of the first shock absorber 4.

[0043] The first tooth portion 224 is made of silicone and has a certain elasticity. When adjustment is required, a rotational force is applied to overcome the meshing force between the first tooth portion 224 and the rod tooth portion 211 to adjust the tilt angle of the first arm 22 .

[0056] Along the direction toward the second shock absorber 5, the cross-sectional area of ​​the second arm piece is arranged to gradually decrease. This makes it easier to transmit the impact force or vibration force along the direction of the second shock absorber 5. At the same time, the relative shaking of the second arm piece is reduced, the transmission stability of the impact force or vibration force is improved, and it helps to improve the concentration of the impact force or vibration force transmission direction, thereby facilitating the transmission of the impact force or vibration force along the direction of the second shock absorber 5.
