[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0028] Please refer to Figure 1 and Figure 2 An electric scooter comprises a body 1, a rear fork 2 and a shock-absorbing connecting assembly 3, wherein the rear fork 2 is rotatably connected to the body 1 via a rotating shaft 4, and the shock-absorbing connecting assembly 3 comprises a shock absorber 31 and a connecting rod mechanism 32, wherein the shock absorber 31 is rotatably connected to the body 1 and the connecting rod mechanism 32 respectively, and the connecting rod mechanism 32 is rotatably connected to the body 1 and the rear fork 2 respectively; a battery 5 is arranged on the body 1, and the shock-absorbing connecting assembly 3 is correspondingly arranged on at least one side of the battery 5; a front wheel 61 is arranged on the body 1, and a transmission-connected motor and a rear wheel 62 are arranged on the rear fork 2, and the motor is electrically connected to the battery 5.

[0029] From the above description, it can be seen that the beneficial effects of the utility model are: the electric scooter has a novel structure, adopts a solution in which the shock absorber 31 is placed in the middle, and the shock absorber 31 is placed on the outside of the battery 5, so as to avoid the shock absorber 31 occupying the space in the length direction of the scooter pedal 11, so that the overall length of the electric scooter is too long, resulting in the inconvenience of packaging and carrying the electric scooter, or resulting in the limited capacity of the battery 5 carried by the electric scooter, resulting in a reduced endurance of the electric scooter.

[0030] In the electric scooter, the shock absorbing stroke of the rear wheel 62 is long, so that the electric scooter has a better shock absorbing effect and off-road performance.

[0031] Furthermore, the shock absorbing connection components 3 are respectively provided on opposite sides of the battery 5 .

[0032] It can be seen from the above description that providing at least two groups of shock-absorbing connection components 3 can improve the shock-absorbing effect to a greater extent, making the riding experience of the electric scooter better.

[0033] Furthermore, the shock-absorbing connection assembly 3 is exposed outside the vehicle body 1 .

[0034] It can be seen from the above description that the exposure of the shock-absorbing connecting assembly 3 is not only convenient for subsequent maintenance, but also convenient for replacing shock absorbers 31 with different performance parameters to meet different usage requirements.

[0035] Furthermore, the vehicle body 1 has a pedal 11 and a protective assembly 12, the pedal 11 is connected to the protective assembly 12, the battery 5 is arranged at the bottom of the pedal 11 and is located in the protective area of ​​the protective assembly 12, and at least a part of the shock-absorbing connecting assembly 3 is located between the pedal 11 and the protective assembly 12.

[0036] It can be seen from the above description that the existence of the protection component 12 can well protect the battery 5 and the shock-absorbing connection component 3, which is conducive to extending the service life of the battery 5 and the shock-absorbing connection component 3.

[0037] Furthermore, the protection assembly 12 includes a first protection pipe member 121 and a second protection pipe member 122 that are fixedly connected, and the rear fork 2 is connected to the second protection pipe member 122 via the rotating shaft 4 .

[0038] Furthermore, the second protective tube 122 is U-shaped as a whole, a part of the second protective tube 122 is located inside the first protective tube 121 , and a supporting foot 15 is rotatably provided on the second protective tube 122 .

[0039] Furthermore, the first protective tube 121 includes a U-shaped portion 1211 and two connecting portions 1212, the two connecting portions 1212 are symmetrically arranged, the two ends of the U-shaped portion 1211 are respectively connected to the two connecting portions 1212, the curved section of the U-shaped portion 1211 protrudes from one end of the pedal 11 close to the rear wheel 62, and the straight section of the U-shaped portion 1211 is located on the outside of the pedal 11.

[0040] As can be seen from the above description, the protection assembly 12 has a simple structure and low production cost. The U-shaped portion 1211 of the first protection tube 121 can play a limiting role, reducing the risk of the user's foot stepping into empty space when using it.

[0041] Furthermore, the damping of the shock absorber 31 is adjustable.

[0042] It can be seen from the above description that the adjustable hardness and softness of the shock absorber 31 can meet the shock absorption requirements of different groups of people for the whole vehicle.

[0043] Furthermore, one end of the shock absorber 31 away from the connecting rod mechanism 32 is connected to the vehicle body 1 via a first rotating shaft 71 , and the first rotating shaft 71 is arranged away from the rear fork 2 .

[0044] It can be seen from the above description that the overall length of the shock absorber 31 can be set to be relatively long, so that the shock absorbing connecting assembly 3 can also play a role in protecting the battery 5 to a certain extent.

[0045] Furthermore, the connecting rod mechanism 32 includes a first connecting rod 321 and a second connecting rod 322, one end of the first connecting rod 321 is connected to the vehicle body 1 through a second rotating shaft 72, one end of the second connecting rod 322 away from the rear fork 2 is connected to the middle part of the first connecting rod 321 through a third rotating shaft 73, and the other end of the shock absorber 31 is connected to the other end of the first connecting rod 321 through a fourth rotating shaft 74.

[0046] From the above description, it can be seen that the connecting rod mechanism 32 has a lever effect, so that the vibration stroke of the rear wheel 62 and the compression stroke of the shock absorber 31 spring form a certain ratio. Through the shock absorption ratio, a smaller stroke and a softer shock absorption spring can be used to meet the shock absorption needs of different groups of people for the whole vehicle.
