Power cut prompting device for tilted or dumped electric vehicle and electric vehicle

Abstract

The invention provides a power cut prompting device for tilted or dumped electric vehicle and electric vehicle. The power cut prompting device includes a direct-current voltage regulated circuit module, a car body angle measurement module, a voice prompting module and a power cut control module. The direct-current voltage regulated circuit module is connected with the car body angle measurement module and the power cut control module. The power cut control module is connected with the car body angle measurement module, the voice prompting module and a controller of the electric vehicle. The car body angle measurement module is composed of single axis tilt angle sensors U2 and U3 with the opposite direction of installation. The voltage output ends of U2 and U3 are respectively connected with two signal input terminals of the power cut control module. When the output voltage of U2 or U3 is or greater than the preset action voltage of the power cut control module, an analog brake signal is generated and the voice prompting module opens. And the analog brake signal is transmitted to the controller of the electric vehicle, and a motor of the electric vehicle is controlled to power off by the controller. The power cut prompting device for tilted or dumped electric vehicle and electric vehicle have the advantages of high stability, low misjudgment and fault rate and simple circuit.

Description

technical field [0001] The invention relates to a power-off prompting device for tilting or toppling of an electric vehicle. The electric vehicle mentioned in the invention refers to an electric bicycle and an electric motorcycle. Background technique [0002] In recent years, with the widespread use of electric vehicles, electric vehicle accidents occur frequently, which has a great impact on traffic control. In order to ensure the safety of electric vehicles, the country has made strict requirements on the braking performance of electric vehicles, the strength of the front fork assembly of the frame, safety devices, and the safety performance of electrical components; Riding electric vehicles on the driveway can ensure safety. However, due to reasons such as weather or slippery road surface, the electric vehicle often tilts or topples accidentally. At this time, the rider often cannot release the acceleration handle of the electric vehicle in time, and even subconsciously...
