Description

Technical Field

[0001] This invention belongs to the field of scooter technology and relates to a two-wheeled scooter and its control method. Background Technology

[0002] Existing two-wheeled electric scooters without handlebars consist of a first and a second frame that rotate relative to each other. The front wheel is mounted on the first frame, and the rear wheel is mounted on the second frame. Gyroscopes are installed on both the first and second frames. Users control the scooter's forward or reverse straight-line movement by swinging the first or second frame left or right with their feet. The swing direction of the frame is perpendicular to the direction of the scooter's movement, which requires users to take a relatively long time to react to the correspondence between the swing direction and the scooter's direction of movement. This is especially problematic for users with slow left-right reactions, as it can easily lead to misoperation and hinders users from quickly and safely mastering the scooter. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by proposing a two-wheeled scooter and its control method, aiming to overcome the defects of existing two-wheeled electric scooters that are prone to misoperation.

[0004] This invention is implemented as follows:

[0005] A two-wheeled scooter includes a frame, a front wheel and a rear wheel respectively mounted on the front and rear ends of the frame, and a motor for driving the front wheel and / or the rear wheel to rotate. The scooter is characterized in that the frame is provided with a tilt detection sensor and a controller, the controller is connected to the motor and the tilt detection sensor, and the front wheel and the rear wheel are offset in the front-rear direction.

[0006] The vehicle body is equipped with foot pedals that can swing left and right to drive the scooter to turn.

[0007] A steering structure is provided between the pedal and the axle of the front wheel and / or the axle of the rear wheel.

[0008] The steering structure includes a steering seat fixed on the wheel axle, the steering seat being rotatably connected to the vehicle body, and the foot pedal having an inclined portion that abuts against the steering seat.

[0009] A cylinder is fixedly mounted on the steering seat, and the inclined portion abuts against the side wall of the cylinder;

[0010] Alternatively, a roller may be rotatably mounted on the steering seat, and the inclined portion abuts against the roller.

[0011] A planar bearing is provided between the steering seat and the vehicle body, and / or, a limiting shaft is provided between one of the vehicle body and the steering seat, and a bearing is provided between the other and the limiting shaft.

[0012] The vehicle body includes a shell, a pivot, a front axle seat, and a rear axle seat. The pivot extends from the front axle seat to the rear axle seat. The pedals include independent front pedals and rear pedals, which respectively drive the front wheel and the rear wheel to steer.

[0013] The contact point where the inclined part corresponding to the front wheel pushes the steering seat to rotate is located behind the rotation axis of the steering seat, and the contact point where the inclined part corresponding to the rear wheel pushes the steering seat to rotate is located in front of the rotation axis of the steering seat.

[0014] The vehicle body is equipped with auxiliary wheels on the opposite sides of the front and rear wheels.

Detailed Implementation

[0025] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] This embodiment provides a two-wheeled scooter, such as Figure 1-5 As shown, the vehicle includes a vehicle body 100, a front wheel 210 and a rear wheel 220 respectively mounted on the front and rear ends of the vehicle body 100, and a motor that drives the front wheel 210 and the rear wheel 220 to rotate. The motor is a hub motor, and the two hub motors are respectively mounted on the front wheel 210 and the rear wheel 220. In other optional embodiments, the motor can also be a regular motor mounted on the vehicle body 100, or it can be a single motor. A single motor can drive a single wheel to rotate or drive two wheels to rotate simultaneously.

[0027] The vehicle body 100 is equipped with a tilt detection sensor and a controller. The controller is connected to the motor and the tilt detection sensor. The front wheel 210 and the rear wheel 220 are offset in the longitudinal direction. This allows the vehicle body 100 to tilt. When the tilt detection sensor detects that the vehicle body 100 is tilted to the right and forward, the controller controls the scooter to move forward. (See reference...) Figure 1 Perspective Figure 1 The top of the scooter is the front. The scooter body 100 can tilt to the upper right, giving it a forward tilt component. This tilt direction can be used as the control method for the scooter's forward movement, ensuring a correspondence between the tilt direction and the direction of travel. This allows the user to quickly control the scooter, avoids misoperation, and improves riding safety. In other optional embodiments, the front wheel 210 can be positioned on the right side of the scooter body 100. In this case, tilting the scooter body 100 to the left and forward controls the scooter's forward movement.

[0028] The tilt detection sensor is a gyroscope. In other optional embodiments, the tilt detection sensor is a distance sensor, which determines the tilt angle of the vehicle body 100 by detecting the distance from the vehicle body 100 to the ground.

[0029] When the vehicle body 100 tilts to the right front, the front wheel 210 and rear wheel 220 will also tilt accordingly, causing the scooter to tend to turn to the right. At this time, the controller can be used to control the speed of the rear wheel 220 to be greater than the speed of the front wheel 210 to maintain balance and ensure that the scooter can travel in a straight line. In other optional embodiments, the front wheel 210 can also be controlled to turn to the left to maintain balance.

[0030] The vehicle body 100 is equipped with foot pedals 300 that can swing left and right to drive the scooter to turn. For example... Figure 4-5 As shown, specifically, a steering structure is provided between the pedal 300 and the axle 230 of the front wheel 210 and the axle 230 of the rear wheel 220. This facilitates the individual control of the front wheel 210 and the rear wheel 220, making it easier to achieve the balance of the scooter. In other optional embodiments, a steering structure can also be provided separately between the pedal 300 and the front wheel 210 or the rear wheel 220. In other optional embodiments, a tilt detection sensor can also be provided on the pedal 300 to detect the left and right tilt angle of the pedal 300, and the controller can control the differential operation of the front wheel 210 and the rear wheel 220 according to the tilt angle of the pedal 300, thereby achieving steering.

[0031] See Figure 1 , 4 5. The steering structure includes a steering seat 410 fixed to the wheel axle 230, the steering seat 410 being rotatably connected to the vehicle body 100, and the foot pedal 300 having an inclined portion 330 that abuts against the steering seat 410. (See reference...) Figure 1 From the perspective of the foot pedal 300 corresponding to the front wheel 210 swinging to the left (i.e., the left side of the foot pedal 300 swings downward), the tilting part 330 pushes the steering seat 410 to rotate counterclockwise, thereby driving the wheel axle 230 to rotate counterclockwise, causing the front wheel 210 to turn the scooter to the left. The scooter's steering does not require controller intervention, reducing the control computation load, decreasing the controller's heat dissipation pressure, and improving steering stability. The steering seat 410 is equipped with a screw-fixed pressure plate 430, and the pressure plate 430 and the steering seat 410 are clamped and fixed to the wheel axle 230.

[0032] like Figure 4-5As shown, a cylinder 420 is fixedly mounted on the steering seat 410, and the inclined portion 330 abuts against the side wall of the cylinder 420. During the process of pushing the steering seat 410, the contact position of the inclined portion 330 changes with the swing angle. The contact between the steering seat 410 and the cylinder 420 and the inclined portion 330 facilitates a smooth transition of the contact position, improving the smoothness of steering operation. The cylinder 420 can be fixed by snap-fit, welding, or screw connection. In other optional embodiments, a roller is rotatably mounted on the steering seat 410, and the inclined portion 330 abuts against the roller, forming rolling friction between the roller and the inclined portion 330, reducing frictional loss and extending service life. In other optional embodiments, the inclined portion 330 can also directly abut against the steering seat 410.

[0033] like Figure 4-5 As shown, a planar bearing 500 is provided between the steering seat 410 and the vehicle body 100; a limiting shaft 510 is provided between the vehicle body 100 and the steering seat 410, and a bearing is provided between the other and the limiting shaft 510. The limiting shaft 510 can restrict the vertical and lateral movement between the steering seat 410 and the vehicle body 100, while ensuring that the steering seat 410 can rotate relative to the vehicle body 100.

[0034] The vehicle body 100 includes a housing 110, a pivot 120, a front axle seat 130, and a rear axle seat 140. The pivot 120 extends from the front axle seat 130 to the rear axle seat 140. The pedals 300 include independent front pedals 340 and rear pedals 350, which respectively drive the front wheel 210 and the rear wheel 220 to steer. The pivot 120 connects the front axle seat 130 and the rear axle seat 140, resulting in a relatively simple structure. A bottom cover 150 is provided below the housing 110 to create a relatively sealed space within the housing 110, facilitating the placement of components such as the battery and controller within the housing 110. In other optional embodiments, the vehicle body 100 may also include a plate-shaped support plate with rotating holes. A pivot post on the pedals 300 is rotatably mounted in the rotating holes. Figure 6 As shown, the housing 110 has a mounting base 111, and the rear axle mount 140 and the front axle mount 130 are fixed to the corresponding mounting base 111 by screws.

[0035] The contact portion of the inclined portion 330 corresponding to the front wheel 210 that drives the steering seat 410 to rotate is located behind the rotation axis of the steering seat 410, while the contact portion of the inclined portion 330 corresponding to the rear wheel 220 that drives the steering seat 410 to rotate is located in front of the rotation axis of the steering seat 410. Thus, when the front wheel 210 and rear wheel 220 are controlled to rotate the scooter in the same direction, the front footrest 340 and rear footrest 350 tilt in the same direction. In other optional embodiments, the footrest 300 may also be a single piece including two footrest areas.

[0036] The foot pedal 300 includes a pedal 310 and a drive unit 320 that are fixedly connected to each other. The drive unit 320 includes two inclined portions 330 that correspond to the two sides of the steering seat 410 respectively.

[0037] like Figure 1-4 As shown, the vehicle body 100 is equipped with auxiliary wheels 240 on opposite sides of the front wheel 210 and the rear wheel 220. This prevents the vehicle body 100 from touching the ground, ensuring smooth movement even when tilted to its limit, preventing sudden stops, improving safety, and reducing ease of use. During normal operation, the auxiliary wheels 240 are not in contact with the ground; only the front wheel 210 and the rear wheel 220 are in contact. When the vehicle body 100 tilts to its limit, the controller puts the scooter into a sleep state, thereby reducing speed and improving safety.

[0038] like Figure 1 As shown, the sides of the housing 110 and the pedal 310 have clearance grooves 600 corresponding to the front wheel 210 and / or the rear wheel 220, and the width of the front end and / or rear end of the vehicle body 100 gradually decreases. This gradual decrease in width at the front and rear ends of the vehicle body 100 creates clearance spaces. When the front wheel 210 and rear wheel 220 are in a turning position, they can be inserted into the clearance grooves 600 or the clearance spaces. This allows the front wheel 210 and rear wheel 220 to be installed closer to the vehicle body 100, reducing the overall width of the scooter. Furthermore, without installing the front wheel 210 and rear wheel 220 under the vehicle body 100, and while maintaining a low footrest area, the front wheel 210 and rear wheel 220 can be made larger. This facilitates the installation of higher-power hub motors on the front wheel 210 and rear wheel 220 and also improves the scooter's maneuverability.
