[0054] As Figures 1-3 shown, the second armrest mechanism 42 includes a second armrest body 421, and the fixed handle 44 extends obliquely or vertically upward based on the second armrest body 421. Thus, it is convenient for the user to grip and conforms to ergonomics.

[0055] It should be noted that the fixed handle 44 of this embodiment is integrally connected to the second armrest body 421, and can be integrally formed by injection molding. Moreover, the fixed armrest extends obliquely upward based on the upper end surface of the second armrest body 421, and the inclined direction is forward.

[0056] As Figure 1 shown, the anti-tilt scooter further includes a lighting lamp 8, and the lighting lamp 8 is installed on the first armrest body 411 and electrically connected to the control unit 5. Thus, it can play a lighting role and is convenient for driving at night or in a dark environment. The lighting lamp 8 can be controlled to be turned on or off by setting a touch button on the display 431, or can also be controlled by setting a switch button on the first armrest body 411.

[0057] As Figures 1-3 shown, the seat part 2 includes a seat main body 21 and a seat cushion 22 detachably installed on the seat main body 21. The seat main body 21 is detachably installed on the moving unit 1, and the first armrest mechanism 41 and the second armrest mechanism 42 are respectively installed on both sides of the seat main body 21. Thus, the seat cushion 22 can be disassembled according to actual needs, such as for cleaning, replacement, etc.

[0058] It should be noted that a connecting block 23 is provided on the side of the seat body 21. The first armrest body 411 and the second armrest body 421 are rotatably connected to the connecting block 23 through a rotating shaft 24. The first armrest body 411 and the second armrest body 421 are provided with limiting sliding grooves 410, and the connecting block 23 is provided with limiting pin shafts 231 that are slidably matched with the limiting sliding grooves 410. The first armrest body 411 and the second armrest body 421 are basically the same in overall shape and are both C-shaped. The limiting sliding grooves 410 are provided at the bottom of the first armrest body 411 and the second armrest body 421 and are opened on the inner side walls. Thus, the rotation of the first armrest mechanism 41 and the second armrest mechanism 42 can be realized to meet various usage requirements, and the limiting of the first armrest body 411 or the second armrest body 421 is realized by the cooperation of the limiting sliding grooves 410 and the limiting pin shafts 231.

[0059] As Figures 6-8 shown, through the cooperation of the limiting sliding grooves 410 and the limiting pin shafts 231, the first armrest body 411 and the second armrest body 421 of this embodiment can at least have 3 usage states:

[0060] Specifically, taking the second armrest body 421 as an example: Assume that the straight line in the horizontal direction is L1, and the straight line where the upper end surface of the second armrest body 421 is located is L2, and the included angle between the two is A.

[0061] Then, preferably, in the normal use state, the angle of A is 0 - 5°, as Figure 3 and Figure 6 shown;

[0062] When the second armrest body 421 is flipped backward, the angle of A is preferably 75 - 95°, as Figure 4 and Figure 7 shown; The beneficial effect of this is that it is convenient for users to get on and off the vehicle. When the user needs to get on and off the vehicle, the first armrest mechanism 41 or the second armrest mechanism 42 can be rotated and flipped backward to get on the vehicle from the side of the car, which is convenient and safe.

[0063] When the second armrest body 421 is pressed forward, the angle of A is preferably 15 - 18°. The beneficial effect of this is that when the user rides on this scooter for work or dining, since the fixed armrest is generally higher than the tabletop, it will be blocked by the tabletop when moving forward directly, resulting in too large a distance between the user and the tabletop, making it impossible to dine or work, etc. In order to adapt to these scenarios, the user can tilt the first armrest mechanism 41 and the second armrest mechanism 42 downward so that the front end of the armrest is lower than the tabletop, and easily enter the appropriate position to dine and work in the most comfortable state.

[0064] It should be noted that, for the convenience of the above state switching, an adjusting handle 25 which is in limit cooperation with the rotating shaft 24 is further arranged on the connecting block 23. The adjusting handle 25 can be movably connected to the connecting block 23 in a hinged manner, and the bottom end can be in limit cooperation with the rotating shaft 24 in a dial manner. A plurality of gear positions grooves corresponding to the dial can be opened on the rotating shaft 24, and this kind of structure can cooperate to achieve the positioning and locking effect.

[0065] As Figures 1-3 shown in the figure, the backrest 3 includes a backrest main body 31 and a backrest cushion 32 detachably mounted on the backrest main body 31. The backrest main body 31 and the seat main body 21 are rotatably connected in a hinged manner. Thus, the backrest main body 31 can be folded relative to the seat main body 21, and the backrest cushion 32 is detachable, meeting the use requirements. The backrest cushion 32 or the seat cushion 22 can be detachably connected to the backrest main body 31 or the seat main body 21 by means of Velcro.

[0066] As Figures 1-3 shown in the figure, preferably, the front wheel 112 of this embodiment is an omnidirectional wheel. It can not only realize basic functions such as moving forward and backward, steering and rotating in place, but also has strong obstacle-crossing ability and is suitable for use in complex road conditions.

[0067] It should be noted that the frame part can adopt the frame structure in the existing technology. For example, the front wheel 112 can be a commercially available Mecanum wheel or an Omni wheel (universal tire) developed by Mazda Motor Corporation.

[0068] As Figures 1-4 shown in the figure, the anti-tilt scooter further includes an expansion part 6. The expansion part 6 is detachably mounted on the front wheel frame 111 and is located between the front wheel group 11 and the rear wheel group 12. Thus, the expansion part 6 can be a storage basket, and its bottom can be detachably matched with the front wheel frame 111 in a card slot limiting manner, while the basket body can be limited by the front wheel frame 111 and the rear wheel frame 121. The expansion part 6 plays a role in storing the items carried by the user, and has strong practicability.

[0069] As Figure 2 shown in the figure, the anti-tilt scooter further includes a rechargeable battery 7. The rechargeable battery 7 is installed on the rear wheel frame 121 and is electrically connected to the single-chip microcomputer 51. Thus, the rechargeable battery 7 is used to supply power to the whole vehicle, and the rechargeable battery 7 can be charged and has a battery life.

[0070] It should be noted that the rear wheel frame 121 is provided with a limiting groove in limit cooperation with the rechargeable battery 7, and an insertion interface electrically connected to the single-chip microcomputer 51 is arranged in the limiting groove. A plug-in part matching with the insertion interface is arranged on the rechargeable battery 7. Preferably, the rechargeable battery 7 is a lithium battery. Thus, the rechargeable battery 7 can be detached, which is convenient to use.

[0071] The present utility model provides a scooter with a brand-new structure. An anti-tipping wheel set 13 is arranged at the rear of the scooter, which can effectively prevent the scooter from tipping over backward, and has good safety. More importantly, a rear shell 14 is arranged at the rear of the vehicle. The rear shell 14 not only imitates the shape of the rear of a sports car in appearance, greatly improving the aesthetics of the scooter, making the scooter more youthful and suitable for a wider range of people, but also can achieve a hidden design of the anti-tipping wheel set 13, avoiding the anti-tipping wheel set 13 from being exposed to wind and sun, playing a certain protective role and extending the service life of the anti-tipping wheel set 13. The rear shell 14 of the present utility model combines aesthetics and practicality.

[0072] The present utility model provides an electric scooter with a brand-new structure. On the basis of a traditional scooter, a fixed handle 44 is added. When in use, the user can hold the fixed handle 44 with the hand that does not control the scooter, which can greatly improve the safety performance and avoid nervousness, especially suitable for scenarios such as uphill, downhill or bumpy roads.

[0073] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
