Gear-shifting parking system for pure-electric delivery vehicle with parking function

Abstract

The invention disclsoes a gear-shifting parking system for a pure-electric delivery vehicle with a parking function. The gear-shifting parking system comprises a storage battery, a VCU (Vehicle Control Unit), an ignition switch, a gear-shifting mechanism, an electronic parking controller, a motor, a mechanical inhaul cable and a parking brake; the storage battery supplies power to the VCU, the gear-shifting mechanism, the electronic parking controller and the motor respectively; the ignition switch is electrically connected with the VCU; the VCU is electrically connected with the gear-shifting mechanism and the electronic parking controller respectively; the gear-shifting mechanism is connected with the electronic parking controller; the gear-shifting mechanism is provided with a gear P; a signal output end of the electronic parking controller is connected with a signal input end of the motor; a rotary shaft of the motor is connected with the mechanical inhaul cable; and the mechanical inhaul cable is connected with the parking brake. According to the gear-shifting parking system provided by the invention, one gear P is added to the existing gear-shifting mechanism with three gears; meanwhile, the gear-shifting parking system is combined with an existing developed electronic parking device and a special switch for electronically parking is cancelled; and functions of shifting the gears and parking are realized through the gear-shifting mechanism after ingenious modification is carried out, and the gear-shifting parking system is convenient and reliable for parking.

Description

technical field [0001] The invention relates to a shift parking system for a pure electric logistics vehicle with a parking function. Background technique [0002] With the development of society and the promotion of national policies, there are more and more companies and models of electric vehicles. At the same time, with the continuous development of the logistics and transportation industry, the demand for pure electric logistics vehicles is also increasing. At present, there are generally two types of pure electric drive methods: one is to use a drive form with a traditional manual gearbox, and the other is to use a direct drive form of a motor. The shifting mechanism that adopts the direct drive mode of the motor is currently an electronic shifting mechanism, generally with three gears D, N, and R. When shifting, the corresponding electrical signal is output to the vehicle controller, and the vehicle controller then controls the gear. The driving state of the vehicle...

Problems solved by technology

[0003] At present, the parking function of pure electric logistics vehicles on the market is still controlled by the mechanical cable of the traditional vehicle. The strength of different drivers is different. The parking brake of the hand parking brake lever may thus affect the actual effect of the braking force. Different, if you pull the parking cable with excessive force for a long time, it is easy to damage the parking cable device, and the driver may forget to pull the parking device, resulting in an accident
