[0025] Reference Figure 1-5 This application presents an embodiment of the scooter, which includes:

[0026] A base 10, wherein a roller 20 is mounted on the rear side of the lower end of the base 10, and the roller 20 is supported on a plane;

[0027] A swing arm assembly 30 is disposed on the front side of the base 10. The swing arm assembly 30 includes two swing arms 31 arranged symmetrically on the left and right. One end of each swing arm 31 is hinged to the base 10, and the hinge axis 32 of each swing arm 31 has an acute angle with the horizontal plane. Both angles are directed upward between the two swing arms 31. The other end of each swing arm 31 is equipped with a caster wheel 33, and the two caster wheels 33 are supported on the plane.

[0028] A seat 50 and a handlebar 60 are disposed between two swing arms 31. The seat 50 is connected to the front side of the base 10 via a first connector 70. The handlebar 60 is mounted on the base 10 via a second connector 80 and is distributed in front of the seat 50. The seat 50 and the handlebar 60 can push the front side of the base 10 up and down under the action of external force and cause the two swing arms 31 to open and close to drive the base 10 forward or backward.

[0029] See attached document Figure 1 and 2 As shown, in the initial state, the two swing arms 31 are close to each other, i.e., in a closed state. At this time, the rider is facing forward, sitting on the seat 50 with hands on the handlebars and feet on the two swing arms 31. The rider adjusts their center of gravity forward and presses down on the seat 50 and handlebars. The front side of the base 10, under the action of the connecting member, moves downward along with the handlebars 60 to... Figure 3 As shown;

[0030] exist Figure 4 and 5 As the height of the front side of the base 10 decreases, the two swing arms 31 open against the tension of the elastic component 40. After the rider adjusts their center of gravity backward and stops pressing down on the handlebars 60, the two swing arms 31 close under the action of the elastic component 40, and at the same time, the height of the front side of the base 10 returns to its initial state. At this time, the seat 50 and handlebars 60 return to their initial state along with the base 10. Figure 2 The state shown;

[0031] The scooter in this embodiment... Figure 2 and Figure 5 The repeated cycles of the state in the middle cause the two swing arms 31 to open and close continuously, thus moving the scooter; by adjusting the installation method of the omnidirectional wheels 33, the scooter can be moved forward or backward by opening and closing the two swing arms 31.

[0032] This application does not specify the installation method of the movable caster 33, as long as it can drive the scooter to move forward or backward when the two swing arms 31 are open or closed. When the two swing arms 31 are open or closed, the resultant force generated by the movable caster 33 moving outward or inward to drive the scooter to move forward or backward is the prior art. This application does not describe in detail the working principle of the base 10 moving forward or backward through the swing arms 31.

[0033] The mounting structure of the omnidirectional wheel 33 in this embodiment is as follows: Figure 1 As shown, the scooter moves forward by the resultant force generated by the outward or inward movement of the swivel wheels 33; in another embodiment, the mounting structure of the swivel wheels 33 can be adjusted so that the two swing arms 31 can drive the scooter to move backward when they open and close.

[0034] The roller 20 is a universal roller 20. When the rider adjusts their center of gravity, the body tilts in the turning direction to adjust the center of gravity, so that the universal roller 20 at the bottom of the scooter slowly adjusts according to the direction of rotation, thus realizing the turning of the scooter.

[0035] In this embodiment, the hinge axis 32 of each swing arm 31 has an acute angle with the horizontal plane, preferably between 30° and 60°, for example, 30°, 40°, 45°, 50°, or 60°, so as to achieve high efficiency when the two swing arms 31 are driven to open and close by moving up and down on the front side of the base 10.

[0036] Preferably, the swing arm assembly 30 is elastically connected to the base 10 via the elastic component 40, or the two swing arms 31 are elastically connected via the elastic component 40.

[0037] In the initial state, the elastic component 40 keeps the two swing arms 31 in the closed position. When the rider adjusts their center of gravity for the first time after riding the scooter, the front of the base 10 is downward and the two swing arms 31 open against the tension of the elastic component 40. When the rider adjusts their center of gravity for the second time, the front of the base 10 is upward. At this time, the restoring force of the elastic component 40 causes the two swing arms 31 to return to the closed position, thus enabling the scooter to move. This makes the movement of the scooter smoother.

[0038] In this embodiment, the swing arm assembly 30 is elastically connected to the base 10 via an elastic component 40, as shown in the attached figure. Figure 3 As shown, the elastic component 40 includes a torsion spring, which is sleeved on the hinge shaft 313, with its two ends abutting against the swing arm 31 and the hinge seat 11, respectively. In another embodiment, the two swing arms 31 can be connected to each other through the elastic component 40; or the swing arms 31 can be connected to the base by a spring.

[0039] Preferably, the other end of each swing arm 31 extends downward at an angle to the omnidirectional wheel 33, which is supported on the plane. Since sufficient space needs to be reserved at the front of the base 10, resulting in a large gap between the front of the base 10 and the plane, in order to ensure that the omnidirectional wheel 33 can be supported on the plane, in this embodiment, the other ends of the two swing arms extend downward at an angle to the omnidirectional wheel 33, which is supported on the plane.

[0040] In another embodiment, the swing arm can also be set horizontally, as long as the omnidirectional wheel 33 can be supported on a plane.

[0041] In this embodiment, preferably, the base 10 is inclined upwards gradually from back to front, and the swing arm 31 is installed on the front side of the base 10 to raise the horizontal height of the front side of the base 10, thereby reserving sufficient space for the base 10 and the swing arm 31 to move. In another embodiment, the base 10 is set horizontally, as long as sufficient space is reserved below the base 10 for its vertical movement.

[0042] In this embodiment, the handlebars 60 are distributed on the front side of the seat 50, and the seat 50 is mounted on the base 10 via the first connector 70. The seat 50 is mounted on the front side of the base 10 via the first connector 70, so that it is easier for the rider to adjust the center of gravity when riding the scooter.

[0043] The handlebar 60 is mounted on the base 10 via a second connector 80, extending the handlebar 60 to the front of the seat 50, making it convenient for the rider to grip the handlebars while sitting forward on the seat 50. Preferably, the second connector 80 is a U-shaped rod, with one end connected to the handlebar 60 and the other end connected to the upper surface of the base 10, so that pressing down on the handlebar 60 can synchronously drive the front of the base 10 to move downward, requiring less effort.

[0044] In this embodiment, the swing arm 31 includes a swing arm body 311, and a hinge seat 11 is provided on the base 10. One end of the swing arm body 311 is hinged to the hinge seat 11 through a hinge shaft 32. One end of the swing arm body 311 is provided with a spring piece 312 and a limiting piece 313 on opposite sides of the hinge shaft 32. The spring piece 312 and the limiting piece 313 abut against the hinge seat 11 respectively. The swing arm body 311 opens and closes against the elastic tension of the spring piece 312.

[0045] The spring piece 312 and the limiting piece 313 limit the swing arm body 311 to a forward-facing state. Preferably, since the limiting piece 313 is not elastic, after the two swing arms 31 rotate to the closed state, the limiting piece 313 can prevent the two swing arms 31 from continuing to close inward, thereby limiting the position of the two swing arms 31 in the closed state to a forward-facing state.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
