Description

Two-wheeled vehicle

Technical Field

The invention relates to the technical field of travel tools or transport tools, in particular to a two-wheel vehicle.

Background

Automobiles generally include basic parts such as power equipment, chassis, body, and electrical equipment. The power plant is a power unit of an automobile, and includes a crank mechanism, a valve train, a cooling system, a fuel supply system, a lubrication system, an ignition system, a starting system, and the like. The chassis is used for supporting and installing the automobile power equipment and the assembly of all parts thereof to form the integral shape of the automobile and receive the power of the power equipment, so that the automobile moves and the normal running is ensured. The chassis consists of four parts, namely a transmission system, a running system, a steering system and a braking system. The automobile body is arranged on a frame of a chassis and used for a driver and passengers to ride or load goods. The electrical equipment consists of two parts, namely a power supply and electric equipment. The power supply comprises a storage battery and a generator; the electric equipment comprises a starting system of the power equipment, an ignition system of the gasoline engine and other electric devices.

In the prior art, a driving system of an automobile generally comprises four wheels, so that the automobile can keep balance in a starting but non-driving state (such as waiting for a traffic light, roadside temporary parking and the like). The energy consumption of a four-wheel automobile is generally larger than that of a motorcycle or a motorcycle-like two-wheel automobile, and at present, the energy supply is continuously reduced, the energy is in short supply and the traffic is increasingly congested, so that green, low-carbon, light and miniaturized automobiles gradually become a new trend of industry development and are favored by more and more travelers.

In fact, compared with the traditional four-wheel automobile, the motorcycle or the motorcycle-like two-wheel automobile has lighter weight, small volume and small contact area with the ground, so that the friction force and the resistance are reduced when the motorcycle or the motorcycle-like two-wheel automobile runs, and the motorcycle or the motorcycle-like two-wheel automobile runs more flexibly and more conveniently. However, motorcycles or motorcycles-like two-wheeled vehicles must be manually kept stable during use, and a slight difference in the pool may cause a safety accident, so that many users are reluctant to or unable to use motorcycles as vehicles instead of automobiles.

Along with the continuous development of economic construction in China, the traffic congestion is increasingly serious. The pressure of driving and parking the vehicle severely hinders people's trip. Therefore, there is a need for a flexible, convenient, economical, safe and reliable vehicle that occupies a small area and combines the common advantages of two-wheeled vehicles and four-wheeled vehicles such as motorcycles and the like. In order to achieve this object, a technology of combining a motorcycle or a motorcycle-like two-wheeled vehicle with a four-wheeled vehicle, such as a two-wheeled car disclosed in application No. 200920080819.8, has been developed in the prior art, and this technology realizes the formation of a car into two wheels and the formation of a car into a two-wheeled motorcycle and a two-wheeled electric vehicle. However, the balance performance of the two-wheel vehicle in the prior art is still not high, so that the safety during driving is not high.

In summary, it is necessary to provide a two-wheeled vehicle which occupies a small area, is flexible, convenient, economical, practical, safe and reliable.

Detailed Description

The invention will be further described with reference to the accompanying drawings and the detailed description below:

referring to fig. 1 and 2, a two-wheeled vehicle includes a power unit (not shown), a vehicle body 1, a chassis 2, and an electric unit (not shown). The power plant is mounted to the chassis 2 and/or the body 1. The power equipment can be at least one of oil-electricity hybrid power, fuel oil power or pure electric power. The vehicle body 1 is mounted to a chassis 2. At least two movable seats (not shown in the figure) are arranged in the vehicle body 1, and the seats can be unfolded and laid flat. Preferably, the movable seat is provided with a massage function. The electrical equipment is installed inside the vehicle body 1, and includes a direction control system, which may be a direction control system having an automatic driving function. The chassis 2 includes a mounting frame 21, and a traveling device 22 and a balancing device 23 mounted on the mounting frame 21. The travel device 22 has two wheels 221. The balancing device 23 may also be mounted to the running gear 22. The balancing device is in a suspended state when the two-wheeled vehicle is retracted inwardly relative to the running device during start-up but not running (such as traffic lights, temporary stops, etc.), during normal running or during cornering, while bringing the two wheels into contact with the ground. The balancing device controls the balance of the two-wheeled vehicle in a vibrating manner during start-up but not driving, during normal driving or during cornering. When the two-wheeled vehicle is turned off, the balancing device extends outwards relative to the running device, and when both wheels are in contact with the ground, the tail end of the balancing device far away from the running device also supports the ground so as to keep the two-wheeled vehicle balanced.

Referring to fig. 3, the balancing device 23 includes a vibrator 231, a detector 232, a controller 233, and a regulator 234. The vibrator 231 is mounted to the adjuster 234. The vibrator 231 and the detector 232 are respectively connected to a controller 234. The adjuster 234 is mounted to the mounting bracket 21. The detector 232 is used to detect the inclination angle of the chassis or the vehicle body. The controller 234 controls the vibration frequency and amplitude of the vibrator 231 according to the result detected by the detector 232. The vibrator 231 drives the regulator 234 to vibrate, and the balance of the two-wheeled vehicle is controlled by the vibration of the regulator 234. The vibrator 231 may be a pneumatic vibrator. The detector 232 may be an infrared detector or a gyroscope or other mechanical detector. The controller 234 may be a microprocessor. Preferably, the balancing devices 23 are respectively disposed at both sides of each wheel 221.

The detector 232 includes a detection unit and a signal generation unit. The detection unit is mounted on the vehicle body or the mounting frame. The signal generation unit is connected with the detection unit and the controller. When the detector 232 is an infrared detector, the detecting unit may be an infrared emitter, and the signal generating unit may be an infrared signal receiver. The infrared emitter is movably mounted to the running gear. When the vehicle body is inclined, the infrared transmitter moves, and the infrared ray received by the infrared receiver changes. For example: infrared emitter installs on ball formula track, when the automobile body left bank, infrared emitter can be along with the automobile body toward left bank and toward left removal, and infrared receiver left side received infrared ray this moment can increase to can obtain the automobile body toward left bank and inclination. Of course the detector may also be a gyroscope, or other detector.

The adjuster 234 includes an adjusting lever 2341 and an auxiliary wheel 2342 mounted on the adjusting lever 2341. The adjusting lever 2341 is movably mounted to the mounting bracket 21. The vibrator 231 is mounted on the adjustment lever 2341. The vibrator 231 can drive the adjusting rod 2341 and the auxiliary wheel 2342 to vibrate, so that corresponding pulling force is generated to drive the vehicle body to return to the right state, and the vehicle body reaches a balanced state.

The regulator 234 further includes a drive motor (not shown). The drive motor is connected to a controller 234. The driving motor is mounted to the mounting frame 21. One end of the adjusting rod 2341 far away from the auxiliary wheel is installed on the driving motor. When the controller receives a signal of a power equipment closing state, the controller starts the driving motor to push the mounting frame out, so that the auxiliary wheel lands on the ground, and the balance of the two-wheel vehicle is kept. When the controller receives a power equipment starting signal, the controller starts the driving motor to recover the mounting frame, so that the balancing device is in a suspension state. The driving motor comprises a telescopic motor, and the telescopic motor is used for controlling the telescopic of the condition lever. In addition, the driving motor can also comprise a corner motor which is used for driving the direction of adjusting the corner of the rod, so that the balancing device can better balance the two-wheeled vehicle.

When the two-wheeled vehicle leans left and right during starting but not running, during normal running or during cornering, there are two cases, the first of which is that when the angle of inclination of the vehicle body is greater than a predetermined angle, since the suspended balancing means will land, it is possible to support the vehicle to place the vehicle in a continuing inclination while returning the vehicle to the right by means of the vibrator, the detector, and the controller. In the second case, when the inclination angle of the vehicle body is equal to or less than a predetermined angle, the balancing device is still in a suspended state, and the vehicle is returned to the right state only by means of the vibrator, the detector and the controller. The predetermined angle may be set according to the vehicle type, the vehicle size, the weight, and the like, and for example, the predetermined angle may be 20 ° to 40 °.

The situation that the vehicle returns to the right by means of the vibrator, the detector and the controller refers to the following contents:

when the two-wheeled vehicle is started, the vibrator, the detector and the controller are powered by the starting of the electrical equipment so as to start operation. The two-wheeled vehicle lands on only two wheels during travel. During normal driving of the two-wheeled vehicle, when the two-wheeled vehicle receives an external force perpendicular to the vehicle driving direction, for example, when the two-wheeled vehicle is tilted in the left or right direction. The detector is used for detecting the inclination angle and the inclination direction of the transverse direction of the vehicle body, transmitting the inclination angle and the inclination direction to the controller and simultaneously obtaining that the two-wheeled vehicle is in a driving state according to the power equipment of the two-wheeled vehicle. The controller calculates the direction and angle required for maintaining the transverse balance of the vehicle body according to the inclined angle and the inclination direction, converts the direction and angle into the frequency required by the vibrator to vibrate, and drives the demodulator to vibrate through the vibrator to adjust the direction and angle of the two-wheel vehicle, so that the balance of the vehicle body is maintained.

For example, when the two-wheeled vehicle is in driving, the detector detects that the vehicle body inclines to the right by 15 degrees, the detector transmits data of inclining to the right by 15 degrees to the controller, and the controller calculates that the vehicle body should incline back to the left by 15 degrees, generates data of inclining back to the left by 15 degrees to control the vibration frequency and amplitude of the vibrator on the left side of the wheel and vibrate the regulator on the left side of the wheel, and the vehicle body is adjusted back.

When the two-wheeled vehicle is started but not running, such as when a situation of waiting for a green light at an intersection is encountered, or in other emergency braking, i.e., the two-wheeled vehicle is not powered off, but stops running. This still only has two wheels touching the ground. In this case, the vehicle body of the two-wheeled vehicle is also inclined in the right-left direction. When the vehicle body inclines, the controller detects the direction and the angle of the transverse direction inclination generated by the vehicle body according to the detector, and obtains that the two-wheeled vehicle is in the starting non-driving state according to the power equipment of the two-wheeled vehicle, and then the detector transmits the information that the angle of the vehicle body inclination in the transverse direction and the two-wheeled vehicle are in the starting non-driving state to the controller. The controller calculates the angle and direction for maintaining the balance of the vehicle body. And then the controller controls the vibrators on the two sides of the wheels to vibrate and respectively generate different vibration frequencies and amplitudes, so that the balance of the vehicle body is maintained. For example, when the vehicle body inclines to the left by about 5 °, the vibration frequency of the right vibrator of the wheel can be 1.5 to 2 times of the vibration frequency and amplitude of the left vibrator and the right vibrator.

When the two-wheeled vehicle is inclined due to turning (generating centripetal force), wind power and collision during running, the detector detects the inclination direction and angle of the vehicle body in the transverse direction and the stress of the two-wheeled vehicle and transmits the inclination direction and angle and the stress to the controller. The controller calculates an angle value of the inclination of the vehicle body in the lateral direction based on these values, and the angle value enables the two-wheeled vehicle to offset the centrifugal force generated by the turning of the two-wheeled vehicle or the external force in the lateral direction by the component of the gravity generated by the inclination of the two-wheeled vehicle in the lateral direction, thereby maintaining the vehicle body in a balanced state. The controller controls the corresponding demodulator to vibrate according to the angle value, so that the balance of the vehicle body is maintained.

Referring to fig. 4, the adjuster 234 further includes an angle adjusting frame 2343; the angle adjusting frame 2343 is provided with a rotating shaft 2344. A through hole is formed in the center of the auxiliary wheel 2342; the rotation shaft 2344 passes through the through hole. When the auxiliary wheel 2342 is mounted on the angle adjusting frame 2343, the auxiliary wheel 2342 and the angle adjusting frame 2343 may be universal wheels. The universal wheel is convenient when the two-wheeled vehicle is started but during not driving, during normal driving or during turning, when the angle of the vehicle body with left and right inclination is larger than a preset value, the universal wheel can change the rotating direction along with the driving track of the two-wheeled vehicle, and therefore the balance of the two-wheeled vehicle is better improved. The friction force between the auxiliary wheel and the ground can be reduced, and the service life of the auxiliary wheel is prolonged.

The angle adjusting frame 2343 comprises a fixing block 2343a, a steering bearing 2343b, a steering shaft 2343c and a wheel frame 2343 d. The fixed block 2343a is fixed to the adjusting rod 2341. The fixed block 2343a and the wheel frame 2343d are respectively provided with a hole. The steering shaft 2343c penetrates through holes of the fixed block 2343a and the wheel carrier 2343 d; and is connected to steering bearing 2343 b; the auxiliary wheel 2342 is mounted on the wheel frame 2343 d. Preferably, the steering bearing 2343b is a universal bearing; for example, the steering bearing may be a 203 mm universal bearing, a 100 mm universal bearing, or a 152 mm universal bearing, among others.

The fixed block 2343a has fixing holes in the left and right sides, and the angle adjusting frame can be fixed to the adjusting rod through the fixing holes. Strong springs 2343e are installed on the left side and the right side of the top end of the steering bearing 2343b, the bottom end of each strong spring 2343e is fixedly connected with the corresponding fixed block 2343a, a wheel frame 2343d is installed on the outer portion of the bottom end of the steering bearing 2343b, and a rotating shaft 2344 is fixedly arranged on the wheel frame 2343 d. The auxiliary wheel 2342 is mounted on the rotating shaft 2344.

As another preferred embodiment, the adjuster may further include a telescopic cylinder, the telescopic cylinder is installed in the adjusting rod, and an output end of the telescopic cylinder is connected with the angle adjusting frame, in which case the angle adjusting frame may not be connected with the adjusting rod. The angle adjusting frame and the auxiliary wheel can be driven by the telescopic cylinder to perform telescopic operation relative to the adjusting rod. This telescopic cylinder work of accessible controller control, when needs the auxiliary wheel and lands, telescopic cylinder can promote angle mediation frame and auxiliary wheel relative regulation pole and outwards extend, when the car starts, then accessible telescopic cylinder can stimulate angle mediation frame and auxiliary wheel relative regulation pole and inwards shrink.

In summary, the chassis of the two-wheeled vehicle comprises the mounting frame, and the running device and the balancing device which are mounted on the mounting frame, wherein the running device runs by adopting two wheels, and the balancing devices which execute the balancing function by vibration are respectively arranged on two sides of the two wheels to realize the balance of the two-wheeled vehicle, so that the body of the two-wheeled vehicle is portable, the balancing device can automatically adjust the inclination direction and the angle of the vehicle, and the safety of the vehicle can be effectively improved; the occupied area is only about half of that of a four-wheel automobile, so that great convenience is brought to people for going out.
