Optionally, the controller 50 can be a programmable microcomputer, a programmable memory, a non-programmable storage, etc., without limitation.

[0070] By setting up a controller 50, the controller 50 is electrically connected to the first driving member 31 and the second driving member 32. The first driving member 31 is suitable for driving the first counterweight 33 to slide relative to the first guide rail 10 according to the inclination angle of the frame 200, and the second driving member 32 is suitable for driving the first counterweight 33 to rotate relative to the first guide rail 10 according to the inclination angle of the frame 200. When the two-wheeled vehicle 1000 is tilted due to external force and driver operation, the controller 50 can control the first balancer 30 and the second balancer 40 to slide and / or rotate according to the inclination angle of the two-wheeled vehicle 1000, so as to keep the two-wheeled vehicle 1000 balanced and prevent the two-wheeled vehicle 1000 from tipping over.

[0071] Please refer to Figure 1 The balance maintaining device 100 also includes a detector (not shown), which is suitable for detecting the tilt angle of the two-wheeled vehicle 1000, and the controller 50 is suitable for receiving the electrical signal of the detector. Optionally, the detector is used to detect the tilt angle of the two-wheeled vehicle 1000 under any circumstances, and transmit the electrical signal to the controller 50, and the controller 50 controls the first balancer 30 and the second balancer 40 according to the electrical signal of the detector. Optionally, the detector can be an infrared detector, a gyroscope, an accelerometer, a pressure sensor, a visual sensor, an angle sensor, etc., without limitation.

[0072] By setting up a detector, the detector is suitable for detecting the tilt angle of the two-wheeled vehicle 1000, and the controller 50 is suitable for receiving the electrical signal of the detector, so that the two-wheeled vehicle 1000 can detect different tilt angles by the detector, and the first balancer 30 and the second balancer 40 can be controlled by the controller 50 to perform corresponding movements, thereby improving the practicality of the balance maintaining device 100.

[0073] Please refer to Figure 1 The two-wheeled vehicle 1000 further includes a front fork 300, which is rotatably connected to the frame 200. The balance maintaining device 100 further includes a sensor 60, which is suitable for being arranged on the front fork 300 and electrically connected to the controller 50. The sensor 60 is suitable for detecting the rotation angle of the front fork 300 relative to the frame 200. The controller 50 is suitable for receiving the electrical signal of the sensor 60. When the front fork 300 rotates relative to the frame 200 and causes the two-wheeled vehicle 1000 to tilt, the first balancer 30 is relatively fixed to the first guide rail 10, and the second balancer 40 is relatively fixed to the second guide rail 20.

[0074] By setting a sensor 60, the sensor 60 is suitable for being set on the front fork 300 and being electrically connected to the controller 50. The sensor 60 is suitable for detecting the rotation angle of the front fork 300 relative to the frame 200. The controller 50 is suitable for receiving the electrical signal of the sensor 60. When the front fork 300 rotates relative to the frame 200 and causes the two-wheeled vehicle 1000 to tilt, the first balancer 30 is relatively fixed to the first guide rail 10, and the second balancer 40 is relatively fixed to the second guide rail 20, so that when the driver is driving the two-wheeled vehicle 1000 at a faster speed and performing normal operations such as turning, the sensor 60 located on the front fork 300 detects the turning action of the two-wheeled vehicle 1000, and controls the first balancer 30 and the second balancer 40 to stop working through the controller 50, so as to prevent the balance maintaining device 100 from affecting the normal operation of the driver.

[0075] Please refer to Figure 1 The first balancer 30 and the second balancer 40 are suitable for synchronous movement. Optionally, the first balancer 30 and the second balancer 40 can also move one after another without limitation.

[0076] By arranging the first balancer 30 and the second balancer 40 to be suitable for synchronous movement, the two-wheeled vehicle 1000 is always kept balanced at both ends in the length direction, and it is not easy to cause the two-wheeled vehicle 1000 to have an abnormal driving state due to the different positions of the first balancer 30 and the second balancer 40 in the width direction of the two-wheeled vehicle 1000, thereby ensuring the safety of the two-wheeled vehicle 1000 and the driver and passenger.

[0077] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0078] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
