Abstract: Disclosed is a self-balancing vehicle including a left housing assembly, a right housing assembly, a left wheel train, a right wheel train and a rotation mechanism. The left wheel train is connected with the left housing assembly. The first end of the rotation mechanism is connected with the right wheel train and the right housing assembly, and the second end of the rotation mechanism is inserted into the left housing assembly and rotationally connected with the left housing assembly. The rotation mechanism is just arranged in the right housing assembly, but connected with the right housing assembly and the right wheel train respectively, thus reducing the strength requirements of the self-balancing vehicle on the left housing assembly and simplifying the components of the left housing assembly.

Abstract: An underwater scooter includes a scooter body, a duct, a motor, and a propeller. The scooter body includes a body part, a side part defining a first through hole, and a plurality of stopping members disposed on an inner wall of the first through hole. A gap is defined between every two adjacent stopping members. The duct includes a surrounding member defining a second through hole, a supporting member connected to an inner wall of the surrounding member, and a plurality of engaging members disposed on an outer wall of the surrounding member and spaced apart from each other. Each of the plurality of engaging members passes through a corresponding gap between two adjacent stopping members and abuts against two opposite sides of a corresponding one of the plurality of stopping members after rotating with respect to the corresponding one of the plurality of stopping members.

Abstract: Disclosed are an optical rotating wheel and a self-balancing vehicle. The optical rotating wheel of the present application includes a stationary component, a moving component, a light source connected with the stationary component, and a laser plate connected with the moving component, in which the stationary component is fixedly connected with the vehicle body and relatively static with respect to the vehicle body, while the moving component is rotationally connected with the stationary component. Moreover, the laser plate is provided with a laser dot which displays a preset pattern under an illumination of the light source, and when the moving component rotates, the preset pattern rotates around the light source. In such a way, a dynamic optical pattern is obtained in the optical rotating wheel and self-balancing vehicle.

Abstract: A wheeled vehicle and a wheel of the wheeled vehicle are provided. The wheel includes a wheel body with a light-emitting module. The light-emitting module includes an LED light bar, a flat mirror, and a two-way mirror. Both a mirror surface of the flat mirror and a reflective surface of the two-way mirror face the LED light bar. A transparent surface of the two-way mirror faces an outer side of the wheel. Looking through the transparent surface, one can see a black hole illusion that the LED lights extend indefinitely into the interior of the wheel, which makes the interior of the wheel appear a hollow visual effect to attract people's attention, thereby increasing the attractiveness of the product for consumers and enhancing the market competitiveness of the products.

Abstract: The invention relates to folding mechanism, scooter using the same, folding and locking methods thereof. The folding mechanism is used for controlling the column of the scooter to fold relative to the footboard of the scooter. The folding mechanism comprising: base, rotating shaft, folding assembly, and triggering assembly for triggering the movement of the folding assembly. The base and folding assembly form a hinge-joint by the rotating shaft, the triggering assembly is disposed in the column, particularly slidably disposed at the side of the folding assembly. Controlling the triggering assembly to slide towards the folding assembly and press against it, can make the folding assembly fold relative to the base, the operation is time-saving and effective, furthermore, the scooter doesn't have exposed part, the structure is compact, which is safe and reliable, meanwhile, it also improves the appearance thereof.
