Description

Technical Field

[0001] This utility model relates to the field of electric scooter technology, specifically to an electric street scooter. Background Technology

[0002] With the increasing demand for short-distance urban travel, electric scooters have gradually become a popular mode of transportation due to their lightweight and agile features. However, traditional electric scooters mostly use chain drive systems, which suffer from problems such as low transmission efficiency, high noise, high maintenance costs, and sluggish power response, especially performing poorly in scenarios involving frequent starts and stops and climbing hills. In addition, chain drives are prone to accumulating dust and gravel, leading to noise and shortened lifespan, thus affecting the riding experience. Utility Model Content

[0003] This invention provides an electric street scooter that achieves efficient and quiet power output through dual-motor belt drive. Combined with a modular layout and protective design, it significantly improves reliability, maintainability, and environmental adaptability. Details such as the external brushless motor and plug-in cable further optimize the user experience, making it suitable for complex urban road conditions.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric street scooter, comprising: a board body, a battery box and a control box installed at the bottom of the board body, and a steering axle installed at the bottom front end of the board body; front wheels are respectively provided at both ends of the steering axle, and the steering axle is connected to the board body through a front axle seat, and a front kingpin is provided between the steering axle and the front axle seat; it also includes a drive axle, the drive axle is connected to the bottom rear end of the board body through a rear axle seat, and a rear kingpin is provided between the drive axle and the rear axle seat; motor frames are respectively connected to the drive axle near both ends, and each motor frame is provided with a drive motor; axle ends are respectively fitted with shaft ends through bearings, the shaft ends are provided with large pulleys, and drive wheels are installed at the free ends of the shaft ends; the output shaft of the drive motor is provided with a small pulley, and a transmission belt is provided between the large pulley and the small pulley; each drive motor and the battery box are electrically connected to the control box.

[0005] Preferably, the rear axle mount has wire grooves on both sides; the drive motor wires extend into the control box through the wire grooves.

[0006] Preferably, the wire is provided with a connector, which is embedded in the wire groove.

[0007] Preferably, the transmission belt is located on the side of the motor frame corresponding to the drive wheel, and a dust cover is installed on the outside of the motor frame.

[0008] Preferably, the drive motor is an external brushless motor.

[0009] The beneficial effects of this utility model are as follows: The modular layout separates the battery box and control box, facilitating maintenance and heat dissipation, while optimizing the center of gravity distribution and improving driving stability. The front wheel achieves flexible steering via the steering axle, while the rear wheel is independently driven via the drive axle, resulting in a clear structure and reduced mutual interference. The front and rear kingpins provide stable rotational pivots, enhancing vehicle handling. The drive axle is independently driven by dual motors, with each motor driving the drive wheel via a transmission belt, achieving power redundancy. Even with a single-sided failure, the vehicle can still operate and its climbing ability is improved. Compared to chain drive, this transmission belt is quieter, requires no lubrication, and provides elastic cushioning to reduce impact and extend component life. The large pulley increases driving force, thus improving the scooter's climbing ability. The cable tray centrally stores the drive motor wires, preventing cable tangling or wear, improving safety and aesthetics. The wires run along the axle base, eliminating the need for complex cable management during disassembly and assembly, simplifying the maintenance process. The connectors are embedded in the cable tray, enabling plug-and-play functionality between the drive motor and control box, facilitating drive motor replacement or wiring repair. Furthermore, the connectors are waterproof, reducing the risk of oxidation or short circuits, while the recessed fixing prevents them from falling off due to driving vibrations. The drive belt is located inside the motor frame, with a dust cover on the outside to block sand, gravel, and rainwater corrosion, extending the life of the belt and pulleys. The dust cover is removable, eliminating the need to disassemble the entire drive axle for cleaning or belt replacement. The external rotor brushless motor has high torque and fast response, making it suitable for street bike scenarios with frequent starts and stops, and its efficiency is higher than that of brushed motors. At the same time, the external rotor structure facilitates heat dissipation, preventing overheating during prolonged operation and improving motor durability. Brushless motors have no carbon brush wear, resulting in a longer lifespan and reduced maintenance costs. Attached Figure Description
