Description

Technical Field

[0001] The present invention relates to the technical field of active balancing of two-wheeled vehicles, and more particularly to an active balancing mechanism and a vehicle. Background Art

[0002] There are approximately 1.85 billion passenger cars worldwide, consuming 140 million tons of standard oil equivalent annually, accounting for approximately 20% of total oil consumption. Nearly 70% of five-seater passenger cars are used by a single occupant. When used by a single occupant, five-seater cars have extremely low energy, road space, and parking space utilization. Annual carbon emissions from passenger cars are approximately 10 billion tons, accounting for 11% of the global total. Compared with four-wheeled five-seater passenger cars, two-wheeled vehicles have two wheels instead of four, which reduces rotational friction. In addition, two-wheeled vehicles can be extremely lightweight and can achieve 70% energy savings. Two-wheeled vehicles can reduce road and parking space usage by 50%, making them a good solution to alleviate road congestion and parking difficulties. Compared with traditional four-wheeled vehicles, the two-wheeled fully enclosed vehicle body has a much higher rigidity due to the halving of the force-bearing surface in the event of a collision or rollover, making the vehicle body less likely to deform and the passengers safer. Two-wheeled vehicles offer a wider field of view and fewer blind spots; Two-wheeled vehicles can be driven by hub motors. If electric four-wheeled vehicles are driven by hub motors, they will encounter technical difficulties in the coordination of the four wheels. Hub motors can eliminate the transmission part, making the system simpler but more efficient.

[0003] Most existing two-wheeled vehicles are closed structures, making it difficult for drivers to perceive the vehicle's balance. Unlike bicycles or motorcycles, they cannot maintain balance by turning the handlebars. Instead, they typically use two mechanical gyroscopes to maintain balance. However, a fatal flaw of mechanical gyroscopes is the enormous energy of the high-speed gyroscope rotors, which poses a significant safety hazard to passengers. For example, when a young man in Shandong was trial-producing a two-wheeled "tumbler" electric vehicle, the gyroscope exploded, resulting in the amputation of the driver's left leg and personal injury. Additionally, when the gyroscope is operating, some of the energy is consumed in maintaining the gyroscope rotor's motion, reducing the efficiency of the two-wheeled vehicle.

[0004] If two-wheeled vehicles do not use mechanical gyroscopes to maintain balance, the safety of the passengers will be greatly improved, and the operating efficiency of the two-wheeled vehicles will also be improved. Summary of the Invention

[0005] In view of the above defects, the present invention provides an active balancing mechanism and a vehicle to solve the above problems.

[0006] To achieve the above object, the present invention adopts the following technical solutions: Active balancing mechanism and vehicle, comprising; Frame; front wheels, used for steering; The rear wheel is mounted on the rear end of the frame for balance; A balancing assembly drives the rear wheel to deflect along a vertical axis at the center of the rear wheel; The front wheel, rear wheel and frame are combined into a two-wheel load-bearing system.

[0007] It includes a shock-absorbing assembly, a horizontal sensor and a telescopic component. The shock-absorbing assembly is used to buffer the vibration between the rear wheel and the frame. The horizontal sensor is fixedly installed on the frame. According to the measurement of the horizontal sensor, when the frame tilts to the left, the telescopic component drives the rear wheel to deflect to the left; when the frame tilts to the right, the telescopic component drives the rear wheel to deflect to the right, thereby changing the center of gravity of the frame and keeping the frame balanced.

[0008] By setting the horizontal sensor, the tilt angle of the vehicle during movement can be tested in real time. The telescopic component can control the deflection angle of the rear wheel. For example, if the left and right tilt angles of the vehicle are set to positive and negative degrees, the positive and negative degrees of the left and right rotation of the rear wheel will correspond in real time. For example, when the vehicle tilts to the left, the motor drives the rear wheel to rotate to the left. If the vehicle regains balance, the motor drives the rear wheel to the middle position. For example, when the vehicle tilts 10 degrees to the right, the motor drives the rear wheel to rotate to the right. The vehicle's tilt state is detected in real time, and a signal is given to the telescopic component at the same time to link the rear wheel with the vehicle's tilt state to keep the vehicle balanced.

[0009] It includes a front steering system, which drives the front wheels to rotate and change the direction of the vehicle.

[0010] Furthermore, the rear wheel is a hub motor, the telescopic component is a screw slider module, and the balancing component includes a V-shaped groove installed on the frame, an arc tube is installed in the V-shaped groove, the center of the arc tube coincides with the center of the rear wheel, a sliding ring is installed on the arc tube, the sliding ring coincides with the center of the arc tube, the moving end of the screw slider module is hinged to the sliding ring, and the fixed end is hinged to the V-shaped groove; a pull rod is installed on one side of the sliding ring, and a 匚-shaped frame is installed at one end of the pull rod, and both sides of the hub motor are fixedly connected to the 匚-shaped frame.

[0011] The hub motor can eliminate the transmission part, making the system simpler and the transmission efficiency higher.

[0012] Furthermore, the shock absorption assembly includes a main shock absorber on the frame, the upper end of the main shock absorber is connected to the frame, the extension line of the main shock absorber in the telescopic direction coincides with the vertical line of the rear wheel center, the main shock absorber can rotate along the vertical line of the rear wheel center, an extension plate is installed on one side of the main shock absorber, the auxiliary shock absorber is installed on the extension plate, the lower end of the auxiliary shock absorber and the main shock absorber are respectively fixedly installed with a 匚-shaped fork, and the lower end of the 匚-shaped fork is hinged to the 匚-shaped frame; the frame is equipped with a power battery.

[0013] The main shock absorber can rotate along the vertical line of the rear wheel center, and the power battery can provide power for the hub motor; the auxiliary shock absorber can be added through the action of the extension plate to improve the shock absorption effect.

[0014] Furthermore, the rear wheel is a common automobile wheel hub, the telescopic component is a hydraulic telescopic rod, the shock absorption assembly includes a type-A shock absorption arm and a knuckle. There are a pair of type-A shock absorption arms which are horizontally hinged on one side of the vehicle frame. The upper type-A shock absorption arm is hinged to the upper end of the knuckle, and the lower type-A shock absorption arm is hinged to the lower end of the knuckle. A shock absorption cylinder is installed between the type-A shock absorption arm and the vehicle frame.

[0015] By setting the rear wheel as a common automobile wheel hub, the adaptability of the wheel hub is improved, and the common automobile wheel hub can also be used, which can significantly reduce the unsprung mass and further improve the comfort and handling performance.

[0016] Furthermore, the balance assembly includes a knuckle protrusion. One end of the hydraulic telescopic rod is hinged to the knuckle protrusion, and the other end is hinged to the vehicle frame.

[0017] Furthermore, it includes an internal combustion engine, a transmission, and an output shaft installed on the vehicle frame. One end of the output shaft is connected to the transmission, and the other end is connected to the common automobile wheel hub. At least two universal couplings are provided on the output shaft. The output end of the internal combustion engine is communicated with the transmission, and the output shaft is installed at the output end of the transmission.

[0018] Furthermore, an auxiliary rod is installed on the vehicle frame. The auxiliary rod is hinged to the vehicle frame. The auxiliary rod is arranged above both sides of the rear wheel. A hydraulic rod is installed at the upper end of the vehicle frame. One end of the hydraulic rod is hinged to the vehicle frame, and the other end is hinged to the auxiliary rod. An auxiliary wheel is installed at one end of the auxiliary rod.

[0019] When the vehicle speed is lower than the tipping speed or the vehicle is stationary, the auxiliary wheel performs a lowering action.

Detailed implementation manners

[0023] The present application provides an active balancing mechanism and a vehicle. Please refer to Figures 1 - 5 : including; The vehicle frame 1; The front wheel 8 for steering; The rear wheel 2 installed at the rear end of the vehicle frame 1 for balancing; The balancing assembly 3 that drives the rear wheel 2 to deflect along the vertical axis of the center of the rear wheel 2; The front wheel 8, the rear wheel 2 and the vehicle frame 1 form a two-wheel bearing system.

[0024] Specifically, in practical applications, the vehicle frame 1 is of a special shape and is used to support the rear wheel 2, the balancing assembly 3 and the shock absorption assembly 4. Through the action of the balancing assembly 3, the rear wheel 2 can be driven to deflect along the vertical axis of the center of the rear wheel 2, thereby changing the center of gravity of the vehicle frame 1 to achieve the purpose of active balancing. Through the action of the shock absorption assembly 4, the vibration between the rear wheel 2 and the vehicle frame 1 can be reduced; the steering function of the front wheel 8 and the balancing function of the rear wheel 2 are separated and distributed to two wheels. The front wheel is mainly used for steering, and the rear wheel is mainly used for balancing.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, including a shock absorbing assembly 4, a level sensor 5 and a telescopic component 6. The shock absorbing assembly 4 is used to buffer the vibration between the rear wheel 2 and the frame 1. The level sensor 5 is fixedly installed on the frame 1. According to the measurement of the level sensor 5, when the frame 1 tilts to the left, the telescopic component 6 drives the rear wheel 2 to deflect to the left; when the frame 1 tilts to the right, the telescopic component 6 drives the rear wheel 2 to deflect to the right, thereby changing the center of gravity of the frame 1 and keeping the frame 1 balanced.

[0026] The use of the level sensor and the feedback and connection with the actuator are existing technologies and will not be elaborated here. For example, the document with application number CN201380041369.0, the application name of which is level sensor for motor vehicle, has the function of detecting the tilt angle of the motor vehicle. Another example is the document with application number CN201210166362.9, in which the balance of the car can be ultimately controlled through measurement by the level sensor.

[0027] By setting the level sensor 5, the tilt angle of the vehicle during movement can be tested in real time, and the electrical signal can be transmitted to the telescopic component 6. The telescopic component 6 controls the deflection angle of the rear wheel 2. For example, if the left and right tilt angles of the vehicle are set to plus or minus 15 degrees, the rear wheel will rotate plus or minus 15 degrees left and right in real time. For example, when the vehicle tilts 15 degrees to the left, the telescopic component 6 drives the rear wheel to rotate 15 degrees to the left. If the vehicle regains balance, the telescopic component 6 drives the rear wheel to the middle position. For example, when the vehicle tilts 10 degrees to the right, the telescopic component 6 drives the rear wheel to rotate 10 degrees to the right. The vehicle's tilt state is detected in real time, and a signal is given to the telescopic component 6 at the same time, so that the rear wheel is linked to the vehicle's tilt state to keep the vehicle balanced.

[0028] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a front steering system, which drives the front wheels 8 to rotate and change the direction of the vehicle.

[0029] Specifically in practical applications, the front steering system can drive the 8 front wheels to steer, which can eliminate the gyroscope of a two-wheeled vehicle, with ultra-high safety performance and reduced energy consumption.

[0030] Example 1 of the balancing component 3, refer to Figure 1 、 Figure 2 and Figure 3The rear wheel 2 is a hub motor 21, and the telescopic component 6 is a screw slider module. The rod slider module is an existing technology, and its main components are a motor, a screw, and a slider. The rotation of the motor drives the screw to rotate, and the slider is threadedly connected to the screw. The rotation of the screw drives the slider to move. The balancing assembly 3 includes a V-shaped groove 31 installed on the frame 1, and an arc tube 32 is installed in the V-shaped groove 31. The center of the arc tube 32 coincides with the center of the rear wheel 2. A sliding ring 33 is installed on the arc tube 32, and the sliding ring 33 coincides with the center of the arc tube 32. The moving end of the screw slider module is hinged to the sliding ring 33, and the fixed end is hinged to the V-shaped groove 31; a pull rod 34 is installed on one side of the sliding ring 33, and a 匚-shaped frame 35 is installed at one end of the pull rod 34. Both sides of the hub motor 21 are fixedly connected to the 匚-shaped frame 35.

[0031] Specifically in practical applications, an electric two-wheeled vehicle can be driven by a hub motor 21. If an electric four-wheeled vehicle is driven by a hub motor 21, it will encounter technical difficulties in the coordinated cooperation of the four wheels. The hub motor 21 can eliminate the transmission part, the system is simpler, and the transmission efficiency will be higher. The operation of the screw slider module can be controlled according to the induction of the horizontal sensor 5. The screw slider module can drive the sliding ring 33 to slide along the arc tube 32. By setting the center of the arc tube 32 to coincide with the center of the rear wheel 2, the rotation center of the sliding ring 33 coincides with the center of the rear wheel 2. The rear wheel 2 can be directly driven to rotate through the action of the pull rod 34 and the V-shaped frame 35; by setting one end of the screw slider module to be hinged to the sliding ring 33 and the other end to be hinged to the V-groove 31, the rear wheel 2 can be stably driven to deflect.

The extension line of the main shock absorber 40 in the telescopic direction coincides with the vertical line of the center of the rear wheel 2. The main shock absorber 40 can rotate along the vertical line of the center of the rear wheel 2. An extension plate 41 is installed on one side of the main shock absorber 40, and an auxiliary shock absorber 42 is installed on the extension plate 41.

[0033] Specifically in actual application, the upper end of the main shock absorber 40 is connected to the frame 1. The bumps generated when the rear wheel 2 runs fast are transmitted to the frame 1 through the auxiliary shock absorber 42 and the main shock absorber 40. The shock absorption of the auxiliary shock absorber 42 and the main shock absorber 40 can improve the driving comfort of the frame 1. When the rear wheel 2 rotates, the main shock absorber 40 can rotate along the vertical line of the center of the rear wheel 2, and the power battery can provide power for the hub motor 21; the auxiliary shock absorber 42 can be added through the action of the extension plate 41 to improve the shock absorption effect.

[0035] Specifically, in practical applications, the rear wheel 2 is provided with a common automobile hub 22, thereby improving the adaptability of the hub and allowing the use of common automobile hubs, significantly reducing the unsprung mass, and improving comfort and handling. The common automobile hub 22 is connected to the clevis 46, and the clevis 46 is horizontally hinged to the vehicle frame 1 through the A-type shock absorber arm 45, so that the clevis 46 can move in the vertical direction. The design of the shock absorber cylinder 47 allows the common automobile hub 22 to achieve vertical bouncing when passing over bumpy roads.

[0036] The second embodiment of the balancing component 3, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The balancing assembly 3 includes a clevis protrusion 36, one end of the telescopic component 6 is hinged to the clevis protrusion 36, and the other end is hinged to the frame 1. The line connecting the two vertical hinge points of the A-type shock absorber arm 45 and the clevis 46 is the rotation axis of the rear wheel 2.

[0037] Specifically, in practical applications, the A-type shock absorber arm 45 and the clevis 46 are vertically hinged, allowing the clevis 46 to rotate horizontally. A rubber sleeve is added to the hinge point to allow the clevis 46 to deflect in other directions to prevent hard contact. The clevis protrusion 36 is provided, and the telescopic component 6 can drive the ordinary automobile wheel hub 22 to deflect, thereby achieving the purpose of balancing the rear wheel 2.

The output end of the internal combustion engine is connected to the transmission, and the output shaft is installed at the output end of the transmission.

[0039] Specifically in practical applications, the power source can be replaced by an internal combustion engine, which transmits power to a transmission and finally transmits power to a common automobile wheel hub 22 via an output shaft.

One end of the hydraulic rod 12 is hinged to the vehicle frame 1, and the other end is hinged to the auxiliary rod 11. An auxiliary wheel 13 is installed at one end of the auxiliary rod 11.

[0041] Specifically, in actual application, when the vehicle speed is lower than the tipping speed or the vehicle is stationary, the auxiliary wheel 13 performs a lowering action. When the vehicle is traveling normally, the auxiliary wheel 13 performs a retracting action. Controlling the elongation of the hydraulic rod 12 can drive the auxiliary rod 11 to rotate downward, driving the lowering of the auxiliary wheel 13 to achieve passive balance. There are two modes of lowering the auxiliary wheel 13; Manual mode, the vehicle speed is less than or equal to 15 kilometers per hour, and the raising and lowering of the auxiliary wheel 13 are manually controlled; Automatic mode, the vehicle speed is less than or equal to 5 kilometers per hour.
