Technical Field

The invention belongs to the technical field of electromechanics, and particularly relates to a multifunctional integrated interlocking device for braking, theft prevention and switch on/off of a two-wheeled electric vehicle.

Background

According to statistics of relevant departments, the possession of two-wheeled electric vehicles in China breaks through 3 hundred million electric vehicles, and the two-wheeled electric vehicles are developed at a high speed every year. Particularly, since a new standard of two-wheeled electric vehicles is developed in recent years, a large number of old standard electric vehicles are about to be updated for standard management, and the pace of replacing fuel-oil motorcycles with electric motorcycles is accelerated. Therefore, experts predict that the first year of implementing the new standard is the year now, and in the coming years, the annual demand of the two-wheeled electric vehicle with the new standard can exceed 5000 thousands of electric vehicles in the domestic market, and the two-wheeled electric vehicle industry in China will come up to the new spring. However, after 30 years of development, although the technology of the two-wheeled electric vehicle is mature, some safety hazards which are easy to neglect still exist in the aspects of parking and anti-theft safety of the vehicle; for example, two-wheeled electric vehicles (including fuel pedal motorcycles) in the prior art have no gears and are not provided with a parking brake device, so that the wheels are still movable during parking, and therefore, the electric vehicles are parked in a place with a certain gradient, and are fixed only by one supporting point of a single-side foot support or extremely easy to slide, and particularly, the electric vehicles can not be parked in the place with a large gradient, but the double-foot support is almost not adopted by people due to the fact that the vehicle body is too heavy; in fact, parking in a flat place, when children climb or are collided unintentionally, or goods are loaded and unloaded, vehicles are easy to shift, even slide and fall, and safety accidents can be caused. Moreover, this obvious safety hazard, which may involve the safety of the consumer's lives and properties, has not been solved yet. In addition, in terms of theft prevention, most people dislike or forget to use the vehicle even if the vehicle head is locked, and therefore, the vehicle is often lost by being pulled in a handy way. After the locomotive is locked, the locomotive and the foot supports are taken as the circle centers, so that the sliding and falling are more easily caused by parking and locking at irregular places; and after the head lock is used, the standard management of vehicle parking in the parking lot is not facilitated.
