A saddle-riding type vehicle comprises a frame extending mainly along a longitudinal direction and comprising front, central, and rear portions. The vehicle comprises a powertrain connected to the frame and comprising at least one electric motor operatively connected to at least one driving wheel. The vehicle also comprises an electrical power supply assembly for powering the electric motor to allow the traction of the vehicle and comprising at least one first pair of batteries arranged on opposite sides with respect to a longitudinal center plane of the vehicle, orthogonal to the axis of rotation of the at least one driving wheel. Each battery is supported by a corresponding support movable between retracted and extended positions, each support being operatively connected to moving means which releases and/or causes the rotation of the support itself around a corresponding axis of rotation to allow the supports to reach the extracted position.

The present disclosure provides a positioning device and a truck. The positioning device includes: a location pin disposed on a location pin mounting base of a battery swap base, a location hole disposed on a location hole mounting base of a battery frame, and a buffer assembly. The location pin is inserted into the location hole. The buffer assembly is disposed at least in one of the following positions: between the location pin mounting base and the location pin, between the location pin and the location hole mounting base, and on the location pin; such that in a case that a hole spacing deviation exists between the battery frame and the battery swap base, the buffer assembly offsets the hole spacing deviation, and in a case that a relative movement exists between the battery frame and the battery swap base, the buffer assembly provides a buffer for shock absorption.

A vehicle includes: a vehicle body having a bottom portion; a power storage device including a main body having a front wall portion, a rear wall portion, and a lower surface; and a flow regulation plate having a distal end portion at a position spaced downward from the bottom portion, a protruding portion is provided on the lower surface side of the main body; in a fixed state in which the power storage device is fixed to the vehicle body, the lower surface is located downward of the bottom portion; the flow regulation plate is provided to be pivotable; and in the fixed state, the protruding portion abuts against the flow regulation plate to maintain a state in which the flow regulation plate covers at least one of the front wall portion and the rear wall portion.

The invention pertains to an electric bicycle (1) comprising a bicycle frame (2) and at least one battery assembly (8) having a drive battery (6), wherein the drive battery (6) comprises a fastening device (12) for detachable fastening to a frame-side holder (10) with a fastening projection (14), characterized in that a receptacle (20) of the drive battery (6) can be brought into engagement with the fastening projection (14) of the holder (10) in such a manner that the drive battery (6) can be pivoted into the holder (10) about the fastening projection (14) and can be locked by means of a latching lever (22).

An electric vehicle battery automatic disconnection system using temperature detection including a battery part configured to provide power to an electric vehicle, a sensor part configured to measure a temperature of the battery part and detect smoke, a connector part configured to charge the battery part, a casing part having an inner space for housing the battery part, and an electronic coupling part configured to couple the casing part to a lower part of the electric vehicle, in which the electronic coupling part is further configured to disconnect the casing part from the lower part of the electric vehicle when the temperature detected by the sensor part exceeds a predetermined threshold or when smoke is detected.
