[0043] The armrest part 4 is installed on the seat part 2;

[0044] The armrest part 4 at least includes:

[0045] The first armrest mechanism 41 is arranged on one side of the seat part 2;

[0046] The second armrest mechanism 42 is arranged on the other side of the seat part 2;

[0047] The control mechanism 43 is installed on the first armrest mechanism 41;

[0048] The fixed handle 44 is installed on the second armrest mechanism 42.

[0049] As Figure 2 shown, the electric scooter with the fixed handle 44 further includes a control part 5. The control part 5 is arranged on the moving part 1. The control part 5 can be a single-chip microcomputer electrically connected to the moving part 1 and the control mechanism 43. The control mechanism 43 includes a display 431 and a direction controller 432 electrically connected to the control part 5. The first armrest mechanism 41 includes a first armrest body 411. Both the display 431 and the direction controller 432 are installed on the first armrest body 411. The vehicle can be controlled to move forward and backward, turn, and rotate in place through the direction controller 432, which is convenient to operate. The display 431, in cooperation with various sensors and network modules, can be used to display temperature, humidity, vehicle speed, and realize various functions such as video calls and voice calls.

[0050] As Figures 1 - 3 shown, the second armrest mechanism 42 includes a second armrest body 421. 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.

[0051] 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. And the fixed armrest extends obliquely upward based on the upper end surface of the second armrest body 421, and the oblique direction is forward.

[0052] 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 part 1. 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.

[0053] 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 a limiting pin shaft 231 that is 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 wall. 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 shaft 231.

[0054] As Figures 6 - 8 shown, through the cooperation of the limiting sliding grooves 410 and the limiting pin shaft 231, the first armrest body 411 and the second armrest body 421 of this embodiment can at least have 3 usage states:

[0055] Specifically, the second armrest body 421 is used for illustration: Assume that the straight line in the horizontal direction is L1, and the straight line where the upper end face of the second armrest body 421 is located is L2, and the included angle between the two is A.

[0056] Then, preferably, in the normal use state, the angle of A is 0 - 5°, as Figure 3 and Figure 6 shown;

[0057] 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 the user 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.

[0058] 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 office work or dining, since the fixed armrest is generally higher than the tabletop, when moving forward directly, it will be blocked by the table board, 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 table board, easily enter the appropriate position, and have meals and work in the most comfortable state.

[0059] It should be noted that for the convenience of switching the above states, an adjusting handle 25 which is in limit cooperation with the rotating shaft 24 is further provided 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.

[0060] As Figures 1 - 3 shown, the backrest 3 includes a backrest main body 31 and a backrest soft body 32 detachably mounted on the backrest main body 31. The backrest main body 31 and the seat main body 21 are rotatably connected by a hinged manner. Thus, the backrest main body 31 can be folded relative to the seat main body 21, and the backrest soft body 32 is detachable, meeting the usage requirements. The backrest soft body 32 or the seat soft body 22 can be detachably connected to the backrest main body 31 or the seat main body 21 by means of Velcro.

Thus, smooth movement can be achieved, and with the front wheels 112 configured in an omnidirectional wheel manner, a flexible steering function can be realized, meeting the travel requirements.

[0062] As Figures 1 - 4 shown, the electric scooter with a fixed handle 44 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 fitted 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 serves to store the items carried by the user, and it has strong practicability.

[0063] As Figure 2 shown, the electric scooter with a fixed handle 44 further includes a rechargeable battery 7. The rechargeable battery 7 is mounted on the rear wheel frame 121 and is electrically connected to the control part 5. 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.

[0064] It should be noted that the rear wheel frame 121 is provided with a limiting groove that cooperates with the charging battery 7 in a limiting manner. An insertion interface electrically connected to the control unit 5 is provided in the limiting groove, and a plug-in member that cooperates with the insertion interface is provided on the charging battery 7.
