The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] like Figures 1 to 3As shown, this embodiment provides a self-balancing tricycle, which includes a flat fork 1, a bracket 2 and a balancing assembly 3, wherein the bracket 2 is rotatably connected to the flat fork 1; the balancing assembly 3 includes a first slider 31, a second slider 32, a reset member 33 and a driving member 34, wherein the first slider 31 and the second slider 32 are respectively slidably matched with the bracket 2 and have a first state of mutual contact and a second state of mutual separation, and the driving member 34 is fixed to the flat fork 1, and when the bracket 2 is subjected to force and rotates relative to the flat fork 1, the driving member 34 causes the first slider 31 and the second slider 32 to change from the first state to the second state, and the reset member 33 always gives the first slider 31 and the second slider 32 a force to change from the second state to the first state. The flat fork 1 of the self-balancing tricycle is used to install tires, and the bracket 2 is fixed to the driver's saddle. When the rider feels discomfort in the waist after riding for a long time, the saddle drives the bracket 2 to rotate relative to the flat fork 1 by moving the waist, and in this process, the driving member 34 drives the first slider 31 and the second slider 32 to switch between the first state and the second state. The reset member 33 always acts on the first slider 31 and the second slider 32 and enables the first slider 31 and the second slider 32 to have a force to maintain the first state or change from the second state to the first state. Therefore, the rider needs to overcome the force provided by the reset member 33 to the first slider 31 and the second slider 32 to change from the second state to the first state through the waist, and the first slider 31 and the second slider 32 can change from the first state to the second state. On the one hand, the self-balancing tricycle is convenient for the rider to exercise the waist and relieve the discomfort symptoms of the waist caused by long-term inactivity. On the other hand, when the bracket 2 is not subjected to external force, the bracket 2 has a self-balancing function of automatically returning to its original position.

[0033] When the tricycle passes through a turning section quickly, the rider has a higher center of gravity and is therefore prone to tipping over under the action of centrifugal force. Therefore, when the tricycle passes through a turning section quickly, the rider can drive the bracket 2 through the saddle to deflect the bracket 2 in the opposite direction of the centrifugal force. This setting can reduce the centrifugal force and reduce the deflection.

[0034] When the tricycle passes through a bumpy road, when the fork 1 and the bracket 2 are fixedly connected, the bumps in the road are directly transmitted to the rider through the bracket 2, and the rider's riding experience is extremely poor. In this embodiment, since the fork 1 is rotatably connected to the bracket 2, the bumps in the road are converted into relative rotation between the bracket 2 and the fork 1, so this setting can reduce the rider's perception of the bumpy road and improve the rider's riding experience.

[0035] As for the specific structure of the reset member 33, optionally, the reset member 33 is a tension spring, one end of which is fixedly connected to the first slider 31, and the other end of which is fixedly connected to the second slider 32. In this embodiment, the tension spring can simultaneously give the first slider 31 and the second slider 32 a force of the same magnitude and opposite directions, thereby switching the first slider 31 and the second slider 32 from the second state to the first state. In other embodiments, a U-shaped spring piece can also be used, one end of which is fixedly connected to the first slider 31, and the other end of which is fixedly connected to the second slider 32. At the same time, a gas pressure spring or a hydraulic spring, as well as other return devices that can realize the reset function, such as an electromagnet, a travel switch, etc., can also be used.

[0036] As for how the driving member 34 causes the first slider 31 and the second slider 32 to change between the first state and the second state, optionally, when the first slider 31 and the second slider 32 are in the first state, the first slider 31 and the second slider 32 are arranged to form an elliptical hole 35; the driving member 34 extends into the elliptical hole 35, and when the first slider 31 and the second slider 32 are in the first state, both ends of the driving member 34 respectively abut against the inner wall at the long axis of the elliptical hole 35. In this embodiment, on the elliptical arc between the major semi-axis and the minor semi-axis of the ellipse, the distance from the center of the ellipse to the elliptical arc gradually decreases. In the first state, the two ends of the driving member 34 are respectively in contact with the inner wall of the major axis of the elliptical hole 35. When the bracket 2 drives the driving member 34 to rotate, and the driving member 34 moves from the major axis to the minor axis, since the two ends of the driving member 34 are respectively slidably matched with the corresponding elliptical arc surfaces on the first slider 31 and the second slider 32, the driving member 34 will change the first slider 31 and the second slider 32 from the first state to the second state; when the driving member 34 moves from the minor axis to the major axis, the driving member 34 will change the first slider 31 and the second slider 32 from the second state to the first state.

[0037] Optionally, the elliptical hole 35 is symmetrical with respect to the gap at the abutment of the first slider 31 and the second slider 32; the rotation axis of the driving member 34 coincides with the axis of the elliptical hole 35, and when the first slider 31 and the second slider 32 are in the first state, the two ends of the driving member 34 respectively abut against the inner wall at the long axis of the elliptical hole 35. In this embodiment, the elliptical hole 35 is symmetrical with respect to the gap at the abutment of the first slider 31 and the second slider 32, and the rotation axis of the driving member 34 coincides with the axis of the elliptical hole 35, so that the driving member 34 can drive the first slider 31 and the second slider 32 to the same displacement.

[0038] Optionally, the driving member 34 includes a driving plate 341 and two sliding wheels 342, the two ends of the driving plate 341 are respectively rotatably connected to the two sliding wheels 342, the two sliding wheels 342 are respectively slidably matched with the inner wall of the elliptical hole 35, and when the first slider 31 and the second slider 32 are in the first state, the two sliding wheels 342 are respectively in contact with the inner wall at the long axis of the elliptical hole 35. In this embodiment, the sliding wheels 342 are respectively provided at the two ends of the driving plate 341 to reduce the friction between the driving plate 341 and the hole wall of the elliptical hole 35, thereby preventing the driving plate 341 from being locked with the hole wall of the elliptical hole 35.

[0039] Optionally, a limiting protrusion 351 is provided along the circumference of the sliding wheel 342 and the circumference of the inner wall of the elliptical hole 35, and a limiting groove 3421 is provided along the circumference of the sliding wheel 342. The limiting protrusion 351 is plugged into the limiting groove 3421. In this embodiment, the plugging of the limiting protrusion 351 and the limiting groove 3421 can prevent the sliding wheel 342 from sliding out of the elliptical hole 35, so that the sliding wheel 342 is always in sliding cooperation with the inner wall of the elliptical hole 35.

[0040] Preferably, the driving plate 341 is elliptical, and when the first slider 31 and the second slider 32 are in the first state, the major axis of the driving plate 341 coincides with the major axis of the elliptical hole 35. In other embodiments, the driving plate 341 may also be a rectangular body or a cylinder.

[0041] Optionally, the bracket 2 includes a limiting frame 21, and the rotating shaft of the flat fork 1 is passed through the limiting frame 21 and rotated with the limiting frame 21. Along the axis direction of the rotating shaft, the limiting frame 21 limits the relative movement of the rotating shaft relative to the limiting frame 21. In this embodiment, the limiting frame 21 limits the relative movement of the rotating shaft relative to the limiting frame 21 along the axis direction of the rotating shaft. This setting can prevent the relative movement of the rotating shaft relative to the limiting frame 21, thereby causing the limiting protrusion 351 and the groove wall of the limiting groove 3421 to be pressed tightly, resulting in an increase in the friction between the limiting protrusion 351 and the limiting groove 3421, and even the limiting protrusion 351 and the limiting groove 3421 cannot move relative to each other due to the large friction.

[0042] Optionally, the bracket 2 further includes a first slide rail 22 and a second slide rail 23, the first slide rail 22 and the second slide rail 23 are fixedly connected to the limiting frame 21, the first slide rail 22 and the second slide rail 23 are spaced apart and arranged in parallel, the first slider 31 and the second slider 32 are located between the first slide rail 22 and the second slide rail 23, the side of the first slider 31 opposite to the first slide rail 22 and the side of the second slider 32 opposite to the first slide rail 22 are simultaneously slidably connected to the first slide rail 22, and the other side of the first slider 31 opposite to the first slide rail 22 and the other side of the second slider 32 opposite to the first slide rail 22 are simultaneously slidably connected to the second slide rail 23. In this embodiment, this arrangement can enhance the stability of the first slider 31 and the second slider 32 sliding on the bracket 2.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
