In at least one embodiment of the present invention, the first installation groove 231 is provided at the front portion of the first handle 23, and the second installation groove 241 is also provided at the front portion of the second handle 24. Specifically, the first mounting groove 231 and the second mounting groove 241 are correspondingly disposed, when the operation member 8 is matched with the first mounting groove 231 or the second mounting groove 241, the hand of the user is usually located at the front portion of the armrest, so that the operation of the operation member by the user is facilitated, and the use convenience of the user is further improved.

In at least one embodiment of the present invention, as shown in fig. 1 to 3, 13 and 14, the number of the operation member 8 may be one, and the user may set the operation member 8 on the first armrest 23 or the second armrest 24 according to the usage habit of the user, so as to meet the usage requirements of different users. The number of the control members 8 can also be two, that is, one control member 8 is arranged on the first armrest 23, another control member 8 is arranged on the second armrest 24, the two control members 8 are different only in control member, and the rest structures are completely the same. Wherein, the control element of one control element 8 is a rocker 81, the control element of the other control element 8 is a key 82, and the user realizes the movement of the scooter by controlling the control element 8 of which the control element is the rocker 81. Therefore, the user adjusts the installation position of the control member 8, which is the rocker 81, by the left-hand or right-hand manipulation habit. When the control member 8, which is the rocker 81, is positioned on the first armrest 23, the control member 8, which is the key 82, is positioned on the second armrest 24; when the control element is the control element 8 of the rocker 81 and is located on the second armrest 24, the control element is the control element 8 of the key 82 and is located on the first armrest 23, that is, the two control elements 8 can be installed in an exchange manner, so that the use convenience of a user is further improved, and the use experience of the user is further improved.

In some embodiments of the present invention, as shown in fig. 1 to 3 and 14, a second adjusting assembly 30 is disposed between the first handle 23 and the seat plate 21, and between the second handle 24 and the seat plate 21, respectively, and the second adjusting assembly 30 is configured to change an angle of the first handle 23 and/or the second handle 24 with respect to the seat plate 21. The user can adjust the handrail to the required position of self through rotating the handrail, has promoted user's use and has experienced. When a user gets on or off the vehicle, the handrail is rotated and folded, so that a larger moving range is provided for the user to get on or off the vehicle. When the user uses the scooter, the user sits on the seat plate 21, then rotates the armrest to the position required by the user, and the arm of the user leans against the armrest, so that the user can drive the scooter in a comfortable posture.

In some embodiments of the present invention, as shown in fig. 4 to 5 and 15 to 17, the quick release structure 3 further includes a conical disc 33 connected to the top end of the guiding post 31, and a through hole is formed in a middle portion of the conical disc 33 and is communicated with the mounting cavity. When a user mounts the seat 2 and the chassis 1, the lower end of the mounting rod 32 only needs to abut against the upper surface of the conical disc 33, and will move towards the direction of the through hole under the guidance of the conical surface of the conical disc 33, and finally the mounting rod 32 falls into the mounting cavity through the through hole. It follows that the provision of the tapered disc 33 can further improve the ease of installation of the seat 2 and chassis 1. The installation difficulty of the seat 2 and the chassis 1 is reduced through the conical disc 33, the seat 2 and the chassis 1 can be assembled without being completely aligned, and the burden of a user during installation is relieved.

In some embodiments of the present invention, as shown in fig. 3 to 5 and 15 to 17, the quick release structure 3 further includes a locking assembly 34 mounted on the guide post 31, the locking assembly 34 having a first state locking the mounting rod 32 and a second state releasing the mounting rod 32. After the seat 2 is installed in the chassis 1, in order to prevent the seat 2 from being separated from the chassis 1 or rotating during the use of a user, the relative position of the seat 2 and the chassis 1 needs to be locked, so that the seat 2 is installed more stably. Further, it is necessary to break the lock between the seat 2 and the chassis 1 to separate them when detaching them.

In some embodiments of the present invention, as shown in fig. 15 to 17, the quick release structure 3 includes a limiting member 35, the mounting rod 32 is provided with a limiting groove 321, the locking assembly 34 includes an operating member 341, a locking nut 342 and a locking block 343, the limiting member 35 sequentially passes through one side of the guide post 31, the limiting groove 321 and the other side of the guide post 31, and the limiting member 35 is matched with the limiting groove 321 to limit the unidirectional movement and rotation of the seat 2. The operating member 341 is rotatably connected to one end of the limiting member 35, the lock nut 342 is connected to the other end of the limiting member 35, the lock block 343 is slidably connected to the limiting member 35 and is located between the operating member 341 and the guide post 31, and the rotation of the operating member 341 relative to the limiting member 35 causes the lock block 343 to move in a direction toward the seat 2 to lock the seat 2 or in a direction away from the seat 2 to unlock the seat 2 from the chassis 1. The rotating shaft of the operating member 341 is perpendicular to the axis of the limiting member 35, the operating member 341 is rotatably connected to the limiting member 35 through a positioning pin, a positioning pin hole is formed in the limiting member 35, the positioning pin is disposed in the positioning pin hole, the axis of the positioning pin hole is perpendicular to the axis of the limiting member 35, the operating member 341 has a cam surface, the cam surface can be regarded as a combined surface of at least two arc surfaces with different radiuses, and the operating member 341 rotates relative to the limiting member 35 to enable different positions of the cam surface to be in contact with the locking block 343, so that the locking block 343 moves in a direction close to the seat 2, and the locking block 343 is tightly pressed on the seat 2, thereby preventing relative movement between the seat 2 and the chassis 1. When the seat 2 needs to be detached, the user rotates the operating member 341 in the opposite direction, and the locking block 343 can slide along the limiting member 35 to move away from the seat 2 to separate from the seat 2, so that the seat 2 can move relative to the chassis 1.

The direction of the limiting member 35 points to the front of the scooter, and after the mounting rod 32 is inserted into the mounting cavity of the guide post 31, the mounting rod 32 can be rotated properly until the limiting groove 321 of the mounting rod 32 is matched with the limiting member 35 in the mounting cavity. At this point, the mounting bar 32 is in the correct position. Through set up spacing groove 321 and set up locating part 35 in the installation cavity on installation pole 32, can guarantee that seat 2 is in predetermined direction after installing on chassis 1 to, also can guarantee the car of riding instead of walk in the use, the angle of seat 2 can not take place to deflect.
