Description

 Electric balance car

 Technical field

 The present invention relates to the field of mobility tools, and more particularly to an electric balance vehicle and an electric balance suitcase.

 Background technique

Electric mobility is now one of the environmental initiatives. Traffic within the city is extremely inconvenient for people to travel because the vehicles occupy a large amount of road resources. Although public transportation can solve the short-distance problem, the last mile of traffic has always been the pain point of going out or going home. Although bicycles or electric bicycles can solve the last mile, the huge size and weight limit people's carry-on and travel.

The traditional electric balance car is designed to control the body posture and achieve steering and front and rear driving. Since the prior art balance cars are all manned and operated, the safety is a serious hidden danger of the traditional balance car because of the high overall center of gravity and the accidents caused by various factors such as uneven road surface or brake inertia.

Common suitcases have drawbars and rollers that are typically used to carry items on planes, trains, and long-distance travel. The suitcases we usually use are basically hand-drawn. Although the existing suitcase can meet the basic needs of carrying articles, it is often not portable and quick because it requires hand-drawing. Especially after people have traveled long distances, dragging heavy suitcases through the long airport corridors makes people physically and mentally exhausted. Therefore, the current suitcase has the disadvantages of being bulky and inconvenient. In the past, the electric box design used longitudinally arranged motor and power wheel, which was inconsistent with the traditional suitcase wheel arrangement. During the drag and drag of the suitcase, the left and right swings were large, the driving was unstable, and the driver and the suitcase were easy to roll over. Therefore, the road surface was required. The flatness is higher. In order to achieve steering, the design of the steering wheel is adopted, resulting in a complicated structure and a large space, which affects the overall arrangement of the suitcase.

Therefore, those skilled in the art are working to develop an electric balance car (box) which has the characteristics of good passability and safety, low center of gravity, simple and light structure, and portability, and becomes a step of public transportation to home and office. tool.

 detailed description

 The technical solutions of the electric balance car and the electric balance suitcase according to the present invention will be described in detail below.

The entire system of the electric balance car consists of three subsystems: electric drive system (motor drive wheel 9), control system (1/3/6/8/13), and structural system (42/5/7).

As shown in Figure 1, the electric drive system consists of a motor-driven wheel (9), and a motor is arranged on each of the left and right sides, so that the left and right wheel speed control realizes the steering of the whole vehicle (box), reducing the complexity of the conventional steering mechanism; The wheel and the drive motor are integrated into a hub motor.

As shown in Figure 2, the control system consists of a controller (8) and a joystick (1), switch (6/13). The switch has four states: Disconnect/Drive/Power/Remote. When the switch (13) is in the 'driving' state, the system is in the 'balanced' state. For safety reasons, the pressure switch under the seat or the left and right foot switches must be turned on at least one to drive. When the push rod is forward and the person's weight is forward, the motor changes the speed to move the car (box) forward. The joystick thrust increases the speed of the car body. When turning, the body and the joystick are turned in the desired direction, and the controller controls the left and right motor speeds according to the steering angular speed, thereby achieving turning.

In order to realize the original telescopic function of the joystick on the suitcase, the invention combines the steering function of the steering gear and the telescopic function of the drawbar, so that the drawbar not only has left and right rotation, but also has a forward angle, and can also be freely retractable and controlled. The space occupied by the pole is also convenient for travel.

During the driving process, there are left and right direction lights on the car (box) body pointing in the direction of travel. The front end of the car (box) body has a nighttime running light, which is convenient for driving in poor light conditions. Similarly, in order to have a night running light at the rear of the safety cabinet, it lights up while the cabinet is running. In addition to normal driving, the fixtures on the cabinet can change color and flashing patterns as needed to reflect their individuality.

The LCD has a LCD screen that displays information such as power and mileage. You can also get information about the battery's power, speed and mileage through the mobile app. The related information can be displayed by remote control or mobile phone, and operation control (such as remote control, fault diagnosis, etc.) can be performed.

As shown in Fig. 3, the switch (13) can be pulled in the 'assisted' state by the stretching rod (1), and the controller controls the motor assist speed according to the traveling speed, thereby reducing the force on the hand of the suitcase. The switch (13) is in the remote control state, and the APP interface can be operated by means of the mobile phone, or the front road condition can be obtained through the camera (11) on the cabinet, and the start, turn and stop commands are issued by the mobile phone.

For example, the auxiliary wheel (102) or the spring leg acts as a balance in the absence or the absence of operation. In the structure of the spring-loaded foot body, the foot can be extended by the upper end of the foot to form a triangular balance support with the wheel. Before driving, you can use the foot to release the release switch on the upper end, and the spring will automatically retract the foot.

As shown in Figure 4, the structure (42/5/7) is the basis for supporting the drive system and the cabinet. It can be made of a tube beam or a plate-like structure to support the strength of the standing or seat of the human body, and the material can be made of aluminum alloy or other lightweight materials.

The foot pedal includes a first sensor that transmits a position state of the foot pedal to the controller; the driver seat includes a second sensor that transmits a state in which the driver seat is seated to the controller.

 Another preferred embodiment of the present invention, Also included is a somatosensory sensor configured to control the electric balancer to advance, retreat, and stop. The stopped brake is configured to be implemented by a brake system mounted on the motor drive wheel and a brake lever on the joystick. Further, the controller has a power assist mode that automatically drives the electric balance vehicle according to the pedestrian speed.

In another preferred embodiment of the present invention, the controller is configured to have Wifi and Bluetooth communication functions, and can communicate with the mobile APP and collect information from the mobile phone. The electric balance car also includes nighttime running lights and street lights, and night running lights and street lights are configured to change colors and flash patterns.
