A straddle-type electric vehicle includes two approximately rectangular parallelepiped batteries, a battery case in which the batteries are housed, battery-side terminals provided on bottom surfaces of the batteries, and case-side terminals engaged with the battery-side terminals. The two batteries are arranged next to each other in a vehicle width direction. An operation lever for connecting or separating the battery-side terminals and the case-side terminals to/from each other is provided. The operation lever is arranged in a middle in the vehicle width direction between the two batteries, and the battery-side terminals and the case-side terminals are arranged nearer outer sides in the vehicle width direction. A pair of front and rear link mechanisms for coupling the operation lever and the case-side terminals to each other is provided in front of and behind the battery case.

Provided are a control method, a vehicle frame, a power driving assembly and a vehicle. The vehicle frame is configured to be connected with the power driving assembly, and the vehicle frame is provided with a manipulation assembly and a controller for controlling the power driving assembly. The control method includes that: after the vehicle frame is connected to the power driving assembly and a communication connection is established between the controller and the power driving assembly, the controller detects a manipulation instruction from the manipulation assembly; and in response to detecting the manipulation instruction from the manipulation assembly and determining that the manipulation instruction corresponds to the power driving assembly, the controller generates, according to the manipulation instruction, a control instruction for controlling the power driving assembly, and sends the control instruction to the power driving assembly.

A vehicle includes a front wheel, a support of the front wheel, a steering handlebar, a platform and a front part joined to the platform. The support is rotatably mounted on the front part, and includes a driven rotating part, the handlebar having a driving rotating part. The driven rotating part and the driving rotating part are connected by Bowden Cables or hydraulic tubes. An impact absorber for a scooter is provided with a support of the front wheel formed by at least a leaf spring including a front end destined to bear the support of the front wheel, an opening adjacent to the front end destined to allow the passage of an upper prolongation of the scooter platform, and a rear end provided with two arms destined to support the rear wheel, such that the impact absorber constitutes the suspension of both the front wheel and the rear wheel.

Presented here is a system and method for creating easy-to-understand notifications of the vehicle state. The notification can be visual or can be auditory and can indicate to the user the vehicle state even when the user's attention is directed elsewhere. The indication can serve to attract the user's attention before more involved information is presented to the user, such as text, or the indication can serve to communicate to the user the vehicle state in an easy-to-understand way such as using color-coded displays or audio indications. The intensity of the indication can be adjusted based on the likelihood that indication will be perceived by the user by, for example, measuring ambient light and/or ambient noise. Reducing the intensity of the indication conserves energy of an energy source associated with the vehicle.

A radar-optical fusion article for attachment to a substrate is described. The radar-optical fusion article includes a first retroreflective layer which is configured to retroreflect at least a portion of light having a wavelength in a range from about 400 nm to about 2500 nm. The radar-optical fusion article includes a second retroreflective layer disposed adjacent to the first retroreflective layer. The second retroreflective layer is configured to retroreflect at least a portion of an electromagnetic wave having a frequency in the range from about 0.5 GHz to about 100 GHz.

A wheel module for a vehicle is disclosed including a wheel, said wheel having a wheel rim; a wheel axle, the wheel rim being rotatably mounted on said wheel axle; and a braking device for braking the wheel, said braking device comprising a brake disc and a brake pad. The brake disc and the brake pad being mutually contactable in order to transmit a braking force F1 to the wheel rim, wherein the brake disc can be axially moved to contact the brake pad and the brake pad remains axially fixed.

A brake unit for a vehicle is disclosed, including a housing, a hydraulic unit, a braking element unit, wherein the braking element unit forms or supports a braking partner in a braking device for the vehicle. The housing, the hydraulic unit and/or the braking element unit define a main axis, wherein the hydraulic unit moves the braking element unit in an axial direction relative to the housing, in order to generate a braking force, and having a guide unit. The guide unit guides the braking element unit in the radial direction during the axial movement, wherein the guide unit has a master guide and an auxiliary guide, wherein the master guide and the auxiliary guide are arranged eccentrically.

A saddle type electric vehicle (1) includes a charging cord (245) that is connectable to an external power supply, a cord accommodating section (230) configured to accommodate a charging cord (245), and a step floor (9) on which an occupant places his/her legs, a center tunnel (CT) bulging above the step floor (9) is provided in front of a front end of a seat (8) and below a handle (2), and the cord accommodating section (230) is disposed in the center tunnel (CT).

The present disclosure provides an electric vehicle. The electric vehicle includes: a handlebar, and an electric vehicle state indicator lamp, wherein the electric vehicle state indicator lamp is located on the handlebar of the electric vehicle, or on an upper portion of a handlebar stem of the electric vehicle, and the electric vehicle state indicator lamp is configured to indicate different vehicle states of the electric vehicle by using different display manners of the electric vehicle state indicator lamp. By adopting the above technical solution, the problem that information on various vehicle states of the electric vehicle only can be known via an instrument screen, causing a high cost and affect a visual effect and the like in the related art is solved.
