However, existing all-terrain electric scooters still have many design shortcomings, especially in terms of passability and comfort, which limits their application scenarios. Most all-terrain electric scooters have shock absorption mechanisms on the rear wheel but not on the front wheel. This results in greater vibration and poor comfort when riding on uneven roads. Some all-terrain electric scooters have damping springs at the lower end of the front fork as shock absorbers, but the damping effect of these springs is not very good. Moreover, since they are mostly vertically mounted, they can only dampen small potholes. When potholes are larger, they cannot effectively cope with the impact of complex road conditions.

If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] like Figures 1 to 3As shown, this utility model discloses an all-terrain electric scooter, including a footboard 1, a front wheel support frame 2, a steering support arm 3, a front wheel 4, and a front shock absorption mechanism. The lower end of the front wheel support frame 2 is fixedly connected to the front end of the footboard 1, and the upper end of the front wheel support frame 2 is hinged to the steering support arm 3. The front shock absorption mechanism is located between the lower end of the steering support arm 3 and the front wheel 4. The front shock absorption mechanism includes an upper front shock absorption support arm 51, a lower front shock absorption support arm 52, a first front shock absorption cross arm 53, a second front shock absorption cross arm 54, and a front shock absorber 55. The upper front shock absorption support arm 51 and the front wheel support frame 2 are arranged in a V-shape, and one end of the upper front shock absorption support arm 51 is connected to the steering support arm 3. The lower end of the front shock absorber support arm 3 is fixedly connected. The lower front shock absorber support arm 52 has a Y-shaped structure and includes a first connection point hinged to the other end of the upper front shock absorber support arm 51, a second connection point hinged to the lower end of the first front shock absorber cross arm 53, and a third connection point connected to the front wheel 4. The upper end of the first front shock absorber cross arm 53 is hinged to the rear end of the front shock absorber 55. One end of the second front shock absorber cross arm 54 is hinged to the end of the upper front shock absorber support arm 51 near the steering support arm 3. The other end of the second front shock absorber cross arm 54 is hinged to the front end of the front shock absorber 55. The middle part of the second front shock absorber cross arm 54 is hinged to the middle part of the first front shock absorber cross arm 53.

[0024] The front shock absorber 55 is disposed between the first front shock absorber cross arm 53 and the second front shock absorber cross arm 54. When the front wheel 4 passes over a pothole, the front wheel 4 moves upward, causing the second connection point of the lower front shock absorber support arm 52 to move upward, which in turn causes the first front shock absorber cross arm 53 to move upward. Since the middle part of the second front shock absorber cross arm 54 is hinged to the middle part of the first front shock absorber cross arm 53, and one end of the second front shock absorber cross arm 54 is hinged to the upper front shock absorber support arm 51, when the first front shock absorber cross arm 53 moves upward, it will cause the end of the second front shock absorber cross arm 54 connected to the front shock absorber 55 to move upward, thereby putting the front shock absorber 55 in a compressed state, thus achieving the shock absorption effect. Because the front shock absorber upper support arm 51 and the front wheel support frame 2 are arranged in a V-shape, the front shock absorber 55 is set at an angle. When the front wheel 4 hits the front part of the pothole, the shock absorber can respond quickly to achieve the shock absorption effect and facilitate the front wheel 4 to pass through the pothole.

[0025] The front wheel shock absorption mechanism has a better shock absorption effect.

[0026] In this utility model, the all-terrain electric scooter also includes a rear wheel support frame 7, a rear wheel 6, and a rear shock absorption mechanism. The front end of the rear wheel support frame 7 is hinged to the rear end of the pedal 1, and the rear wheel 6 is mounted on the rear end of the rear wheel support frame 7. The rear shock absorption mechanism includes an upper rear shock absorption support arm 81, a lower rear shock absorption support arm 82, and a rear shock absorber 83. One end of the upper rear shock absorption support arm 81 is fixedly connected to the pedal 1, and the other end is connected to the upper end of the rear shock absorber 83. One end of the lower rear shock absorption support arm 82 is hinged to the rear end of the rear wheel support frame 7, and the other end is hinged to the lower end of the rear shock absorber 83. When the rear wheel 6 passes over a pothole, the rear wheel support frame 7 rotates upward. At this time, the lower rear shock absorption support arm 82 will compress the rear shock absorber 83, thus achieving the shock absorption effect of the rear wheel 6.

[0027] In this embodiment, the rear shock absorber is located on one side of the rear wheel 6. Of course, a rear shock absorber can also be located on each side of the rear wheel 6.

[0028] In this invention, the front wheel 4 has a diameter of 18-20 inches. This significantly improves the road passability and riding comfort of the all-terrain electric scooter, and also enhances the stability and safety of the vehicle in complex terrain.

[0029] In this invention, the front shock absorber 55 and the rear shock absorber 83 are both pneumatic or hydraulic shock absorbers. Of course, they can also be spring shock absorbers. Since the front shock absorber 55 and the rear shock absorber 83 are separately installed on the front and rear shock absorption mechanisms, they can be used interchangeably with existing shock absorbers for bicycles, motorcycles, or electric bicycles. This reduces maintenance difficulty and costs, and has good practicality and promotional value.

[0030] In this invention, the front wheel support frame 2 and the steering support arm 3 are both made of aluminum alloy plates or carbon fiber plates spliced ​​together, which can reduce the weight of the scooter while ensuring strength.

[0031] In this invention, the upper end of the front wheel support frame 2 is connected to the steering support arm 3 via a bearing to ensure steering flexibility.

[0032] In this utility model, the front shock absorber 55 is provided with a quick-release structure at both ends. The quick-release structure includes a fixing screw and a rotating handle hinged to the fixing screw, which facilitates the maintenance and replacement of the front shock absorber 55.

[0033] In this invention, the front shock absorber upper support arm 51, the front shock absorber lower support arm 52, the first front shock absorber cross arm 53, and the second front shock absorber cross arm 54 are all symmetrically arranged in pairs, and the front wheel 4 is located between the two front shock absorber lower support arms 52. This ensures effective support and connection strength.

[0034] In this utility model, the upper end of the steering support arm 3 is provided with a steering handle 9 for hand support and steering control.

[0035] In this invention, the pedal 1 is equipped with a battery assembly for electronically controlled driving.

[0036] This invention features a simple structure and high reliability, significantly enhancing the scooter's impact resistance and obstacle-crossing performance, making it suitable for more diverse road conditions, and also providing better comfort and lower maintenance costs.

[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
