Description

Technical Field

[0001] The utility model relates to the technical field of two-wheeled electric vehicle balancing, in particular to a gyroscope balancing drive mechanism for a two-wheeled electric vehicle. Background Art

[0002] Electric vehicles, that is, electric-driven vehicles, are also called electric-drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Electric vehicles generally use batteries as their energy source, and convert electrical energy into mechanical energy movement through controllers, motors and other components to control the current size to change the speed of the vehicle. As a green sunrise industry, electric vehicles have been developed in China for ten years. Due to strong demand, China's electric bicycle market has maintained leapfrog growth in recent years.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN208963236U, which discloses a two-wheeled electric vehicle gyroscopic balance drive mechanism, which belongs to the field of new energy electric vehicle technology, and solves the technical defects that the traditional drive mechanism structure cannot fully achieve balance, has the risk of rollover, has poor safety performance, and has easy motor failure. It mainly includes a frame, an electronic control unit, a gyroscope, an electromagnetic clutch, and a motor. The utility model is very cleverly conceived, and cleverly utilizes the separation and combination function of the electromagnetic clutch, which not only satisfies the gyroscope's free adjustment of the precession angular velocity, but also ensures the service life of the motor; the balance performance is very good, the safety performance is very strong, and the service life is very long. It effectively overcomes the defects of traditional technology, greatly promotes the development of the front and rear two-wheeled electric vehicle industry, and is of great significance in the field of new energy technology for electric vehicles.

[0004] The existing balancing structure generally keeps the two-wheeled electric vehicle balanced by rotating the gyroscope driven by a motor. This method requires continuous driving of the flywheel to keep the flywheel rotating in order to keep the vehicle balanced, which will cause energy loss and reduce the endurance of the electric vehicle. At the same time, the existing balancing structure can only maintain the balance of the electric vehicle. The vehicle needs to be balanced by external force to avoid tipping over, and the inclination angle of the vehicle body cannot be adjusted according to the state of the vehicle body.

[0028] The permanent magnet motor 12 is installed at the center of the limiting frames 11 on the front and rear sides of the support plate 2 in a mirror-symmetrical manner with the center of the support plate 2 as a reference.

[0029] The permanent magnet motor 12 is fixedly connected to the connecting plate 1 through the limiting frame 11 , and the end of the rotating shaft of the permanent magnet motor 12 is inserted into the inside of the limiting bearing 17 .

[0030] The limiting frame 11 and the fixing frame 15 are of an "X"-shaped structure. The connecting columns 14 are installed in an "X"-shaped manner at the four corners of the rear side of the limiting frame 11 with the center of the limiting frame 11 as a reference. The fixing frame 15 is fixedly connected to the limiting frame 11 through the connecting columns 14.

[0031] Specifically, the connecting plate 1 can limit the position of the limit frame 11, the limit frame 11 can limit the position of the permanent magnet motor 12, the permanent magnet motor 12 can drive the flywheel 13 to rotate, and the flywheel 13 can generate angular momentum when rotating. The connecting column 14 can limit the relative position between the fixed frame 15 and the limit frame 11. The fixed frame 15 can facilitate the connection between the device and the vehicle and limit the position of the end of the rotating shaft of the permanent magnet motor 12. The limit bearing 17 can reduce the relative friction between the end of the rotating shaft of the permanent magnet motor 12 and the fixed frame 15.

[0032] A support plate 2 is fixedly installed on the right side of the connecting plate 1, a connecting frame 21 is fixedly installed below the support plate 2, a rangefinder 22 is inserted through the left side of the connecting frame 21, a connecting block 23 is fixedly installed inside the support plate 2, a fixed bearing 24 is embedded inside the connecting block 23, a connecting shaft 25 is inserted through the center of the fixed bearing 24, a baffle 26 is fixedly installed below the connecting shaft 25, a counterweight 27 is fixedly installed at the lower end of the baffle 26, and a controller 28 is fixedly installed above the support plate 2.

[0033] The distance meter 22 is installed on the left and right sides of the connecting frame 21 with mirror symmetry based on the center of the connecting frame 21, and the connecting block 23 is installed on the front and rear sides of the supporting plate 2 with symmetry based on the center of the connecting shaft 25.

[0034] The connecting shaft 25 is rotatably connected to the connecting block 23 via the fixed bearing 24 , and the lower end of the baffle 26 is located between the distance meters 22 .

[0035] Specifically, the support plate 2 can support the controller 28, the connecting frame 21 can limit the position of the rangefinder 22, the rangefinder 22 can detect the distance between it and the baffle 26, the connecting block 23 can limit the position of the connecting shaft 25, the fixed bearing 24 can facilitate the rotation of the connecting shaft 25, the connecting shaft 25 can facilitate the position of the baffle 26, the baffle 26 can rotate with the axis of the connecting shaft 25 as a reference, the counterweight block 27 can facilitate the rotation of the baffle 26, and the controller 28 can adjust the rotation speed and rotation direction of the permanent magnet motor 12 according to the detection data of the rangefinder 22.

[0036] When in use, it is necessary to make the axis of the flywheel 13 and the axis of the rear wheel of the electric vehicle in a non-planar and vertical state. Since the lower end of the baffle 26 is located between the rangefinder 22, the rangefinder 22 can detect the distance between it and the baffle 26. Since the baffle 26 is fixed below the connecting shaft 25, the connecting shaft 25 is rotatably connected to the connecting block 23 through the fixed bearing 24. When the electric vehicle tilts, the baffle 26 will remain in a vertical state under the influence of the lower end counterweight 27, and the rangefinder 22 will tilt with the tilt of the vehicle body. The detection data of the rangefinder 22 on one side of the connecting frame 21 will increase and that on the other side will decrease. The controller 28 will turn the connecting frame 21 to the vertical position. The monitoring distance of the side rangefinder 22 is subtracted from the monitoring distance of the other side of the connecting frame 21 to obtain a difference. The rotation direction of the permanent magnet motor 12 is determined according to the positive or negative value of the difference, and the speed of the permanent magnet motor 12 is determined according to the size of the difference, so that the permanent magnet motor 12 drives the flywheel 13 to rotate to generate an angular momentum opposite to the tilt direction of the vehicle body to adjust the tilt angle of the vehicle body. The controller 28 can continuously adjust the tilt angle of the vehicle body by controlling the rotation of the permanent magnet motor 12 to make the difference of the monitoring data of the rangefinder 22 equal to zero. In the process of the difference of the monitoring data of the rangefinder 22 returning to zero, the vehicle body will tend to a vertical state, thereby achieving the effect of adjusting the tilt angle of the vehicle body.
