The stator is provided with a stator core having tooth portions and boot portions and a plurality of coil windings wrapped around the tooth portions. The stator is disposed radially in relation to the magnetic rotor such that the magnetic poles are radially polarized to produce radial magnetic flux density, and the magnetic flux density is substantially higher at both edges than middle portion of each magnetic pole in the circumferential direction.

A battery attaching/detaching structure for a saddle-type vehicle including: a plurality of substantially rectangular parallelepiped batteries for supplying electric power to a power source of the saddle-type vehicle; a battery case in which the batteries are stored; battery-side terminals provided on lower surfaces of the batteries; and case-side terminals engaged with the battery-side terminals, comprises terminal holders that support the case-side terminals such that the case-side terminals are movable between a connected position where the case-side terminals are connected to the battery-side terminals and a retracted position where the case-side terminals are separated from the battery-side terminals. Between the case-side terminals and the terminal holders, springs for urging the case-side terminals in a direction of pressing the battery-side terminals are disposed. Such battery attaching/detaching structure is capable of limiting the movement of a stored battery and maintaining good electrical connection between a battery-side terminal and a case-side terminal.

A handlebar foldable mechanism and a tool for riding instead of walk are provided. The handlebar foldable mechanism includes a base, a stem, a first locking assembly, a lever and a second locking assembly. The base is provided with a first snapping groove, the stem is connected to the base and is pivotable between an unfolded position and a folded position, the first locking assembly is pivotably connected to the stem and is configured to be engaged with the first snapping groove when the stem is pivoted from the folded position to the unfolded position, the lever is pivotably connected with the base, the second locking assembly is mounted to the lever, and the second locking assembly is configured to be connected to at least one of the base and the stem when the stem is at the unfolded position.

Disclosed are a foot plate for a self-balancing scooter, and a self-balancing scooter. The foot plate (1) for a self-balancing scooter comprises a main body (10) and touch control portions (11). A front side and a rear side of a lower surface of the main body are both connected to the touch control portions, which protrude downwards and are used to trigger a sensor on a self-balancing scooter. The touch control portions at the front side and the rear side of the lower surface of the foot plate for a self-balancing scooter are capable of directly triggering corresponding sensors. The foot plate is applicable to twisting scooters having a left scooter portion and a right scooter portion which are capable of twisting relatively. No additional components are required, and users just need to install the foot plate on a self-balancing scooter. The foot plate has a simple and logic structure, and a self-balancing scooter adopting the foot plate is compact in overall structure, easy to install, convenient to operate, better in control performance, and longer in service life.

A pedal connection mechanism includes a left and a right pedal, and a transverse connecting member. The first cylindrical shaft is provided along the bottom of the left pedal. The left side of the top wall of the transverse connecting member is provided with the first support member. The second cylindrical shaft is provided along the bottom of the right pedal. The right side of the top wall of the transverse connecting member is provided with the second support member. The present invention further provides an electric balancing vehicle using this pedal connection mechanism. The left pedal and the right pedal are not connected with each other through an intermediate shaft. Their motion statuses are controlled respectively by the left foot and the right foot independently. The transverse connecting member shares the weight of a human body. The force distributes evenly. The balancing vehicle is flexible and durable.

A shock absorber and a transportation tool. The shock absorber includes a first rotating arm; a second rotating arm pivotally coupled to the first rotating arm; and a torsion bar spring having a first end coupled to the first rotating arm and a second end coupled to the second rotating arm, wherein an included angle between the first rotating arm and the rotating arm has a set value. The shock absorber has a simple structure and good shock absorption effect and adjustable stroke.

A vehicle includes a right front wheel, a left front wheel, a brake operator, grips, and a steering force transmission which transmits a steering force to the right front wheel and the left front wheel. The steering force transmission includes a steering shaft, a handlebar, and a tie rod. Brake operators, which operate the brakes, and the grips are located on the handlebar, and a rubber damper located on the steering force transmission significantly reduces or prevents vibrations from being transmitted to the grips, wherein the vibrations are due to a difference between a frictional force generated between the right front wheel and a corresponding road surface and a frictional force generated between the left front wheel and a corresponding road surface.

A four-wheel sensor controlled vehicle having a base and a control box installed with a battery and a control panel; two driving wheels are installed at the bottom surface of the base close to the front edge of the base, and two universal wheels are installed at the bottom surface of the base close to the rear edge of the base. The driving wheel has a hub assembled with a hub motor assembly of a motor. The base is installed with four weighing sensors at four corners, the first weighing sensor and the third weighing sensor respectively correspond to the fore sole and rear sole of the left foot, the second weighing sensor and the fourth weighing sensor respectively correspond to the fore sole and the rear sole of the right foot. The control panel is connected with the motor and the weighing sensors.
