Electric vehicle electronic lock forced unlocking device, electronic lock, charging socket, vehicle-mounted charger and electric vehicle

Abstract

The invention discloses an electric vehicle electronic lock forced unlocking device, an electronic lock, a charging socket, a vehicle-mounted charger and an electric vehicle. The electric vehicle electronic lock forced unlocking device includes a forced unlocking button, one end of the forced unlocking button is connected to a 12V direct current power supply positive pole, and the other end is connected to a central control unit in a control circuit through a button signal detection circuit, and the central control unit sends a forced unlocking signal while detecting a button signal. The electric vehicle electronic lock forced unlocking device provided by the invention meets the emergency unlocking requirement under an emergency situation, employs the electric unlocking way to solve various defects existing in current mechanical way, is conducive to enterprise processing, and has low requirement for the electronic lock itself. The invention also adopts a button type unlocking way, the installation position of the button can be set in accordance with the user needs, the forced unlocking button is disposed at a vehicle-mounted charger, a charging socket or other positions, the electric vehicle electronic lock forced unlocking device is easy in wiring and convenient for the user to operate, has more humanized design, and realizes effective unification of simple processing and convenient operation.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a forced unlocking device for an electric vehicle electronic lock, an electronic lock, a charging socket, a vehicle charger and an electric vehicle. Background technique [0002] With the development of social economy, the demand for energy is further increased, the voice of new energy technology is getting higher and higher, and electric vehicles are also receiving more and more attention. Electric vehicles are driven by power batteries. Battery pack charging, how to charge electric vehicles is an important topic. [0003] There are currently two charging methods for electric vehicles or gasoline-electric hybrid vehicles, namely AC charging and DC charging. As the country's requirements for charging safety and reliability continue to increase, relevant safety technical standards are also constantly being updated. [0004] Among them, in GB / T 18487.1-2015, it is clearly stipulat...

Problems solved by technology

[0007]Due to various situations in the charging process, it is necessary to pull out the charging cable, for example: need to use before charging is completed, charging failure, special circumstances need to cancel charging immediately And pull out the charging gun, etc., but the charging is not completed at this time, the controller cannot intelligently respond to these requirements, that is, immediately send the electronic lock unlock signal, and the charging plug will be locked and cannot be pulled out, which seriously affects the application. flexibility

[0008] In order to solve these problems, some manufacturers of charging connectors also adopt mechanical solutions to deal with this problem, such as extending a lock on the electronic lock of the charging socket The pull-out line connected to the stop pin can be unlocked by pulling the pull-out line to retract the lock pin, but this method has certain requirements for the structure of the electronic lock itself, for example, a motor and a transmission structure are generally required to enable the lock pin to Retract by pulling, poor versatility

[0009]In addition, since the charging socket is installed on the vehicle body, the protruding end of the locking pin needs to face out of the vehicle body to realize the locking function. The pulling wire can only be directed towards the inside of the car body. If you want to pull the pulling wire outside the car for manual unlocking, the pulling wire needs to pass through the inner wall of the car to the outside of the car. This phenomenon has occurred in many main engine factories, which has brought great troubles to the manufacturers. Therefore, some manufacturers often only have to install the pulling wires in the car during the manufacturing process, which in turn brings inconvenience to the user's operation. , the contradiction between the two becomes an urgent problem to be solved

[0010] Moreover, even if the drawing wire can be extended to the outside of the vehicle, and in this structure, the drawing wire needs to be bent before changing its direction. The requirements for its own strength and wear resistance are high, and the requirements for installation are also high, and because the drawing wire is bent, the resistance during operation will increase accordingly, which will bring great benefits to the actual use of users. the inconvenience
