Technical field
The utility model belongs to the auto parts machinery technical field, relates to a kind of key switch device, relates in particular to a kind of key switch device that is complementary with electric automobile.
Background technology
At present, the startup of automobile all realizes vehicle launch by the key turns key switch, the startup of orthodox car is exactly earlier key switch to be turned to " START " shelves to come ato unit, return " ON " shelves by key switch then and make the automobile operate as normal, and electric automobile is to replace engine by storage battery to provide the energy for the driving of vehicle, drive motors also is to start voluntarily, there is no need to keep " START " this gear, therefore, existing repacking on the key switch basis of orthodox car and the key switch of the electric automobile that comes can't be complementary with the actual functional capability of electric automobile driving control.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, a kind of cancellation " START " has been proposed thus gear can not only be simplified the key switch structure, and make it more can meet the electric automobile key switch device of electric automobile function needs.
The purpose of this utility model can realize by following technical proposal: a kind of electric automobile key switch device, comprise key switch, this key switch comprises lock housing and is positioned at the lock core of lock housing, described lock core is provided with keyhole and can rotates in lock housing, it is characterized in that: described lock housing is provided with signaling switch and the locking retaining " LOCK " that is connected with signaling switch, start retaining " ACC " and work retaining " ON " three gears, above-mentioned lock core can come back rotation respectively in above-mentioned three gears, this electric automobile key switch device also comprises the entire car controller that is connected with above-mentioned signaling switch, when lock core turns to above-mentioned locking retaining " LOCK " respectively, when starting retaining " ACC " and work retaining " ON ", can send the locking signal respectively by the triggering signal switch, enabling signal and working signal are given entire car controller, and entire car controller can carry out the dump car load to car load respectively and not work, the operation that storage battery low-voltage power connection and car load on-board high-voltage system forceful electric power are connected.
When using the key switch of this electric automobile, insert keyhole by key, can control lock core and turn to " LCOK " shelves, " ACC " shelves or " ON " shelves, when lock core turns to " LOCK " shelves, the triggering signal switch sends the locking signal to entire car controller, by entire car controller processing signals and control system outage, make car load quit work, similarly, when lock core turns to " ACC " shelves and " ON " shelves, triggering signal switch transmission enabling signal and working signal by controlling forceful electric power in storage battery low-voltage power connection and the car load on-board high-voltage system respectively after the entire car controller processing, impel the startup and the work of vehicle to entire car controller respectively.
In above-mentioned a kind of electric automobile key switch device, be equiped with control chip MCU in the described entire car controller, have " acc " and " on " two signal input pins on the control chip MCU, above-mentioned signaling switch is connected with two signal inputs of " acc " and " on " respectively.Working signal that " ACC " grade enabling signal that triggers and " ON " shelves trigger is sent in the interior MCU chip of entire car controller by " acc " signal input pin and " on " signal input pin respectively, sends the operating state of control signal control vehicle after being handled by the MCU chip.
Compared with prior art, " START " shelves in the existing key switch have been cancelled in this electric automobile key switch device, between " LOCK " shelves and " ON " shelves, set up " ACC " shelves, connect the storage battery low-voltage power supply by selecting " ACC " shelves, impel vehicle-mounted bus initialization and car load low pressure annex to start working, carrying out the transition to " ON " shelves then comes to forceful electric power in the on-board high-voltage system, drive the electric automobile operate as normal, can agree with mutually with the actual functional capability of electric automobile driving control better.
Description of drawings
Fig. 1 is the theory structure block diagram of this electric automobile key switch device.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, a kind of electric automobile key switch device, comprise lock housing, be positioned at the lock core and the entire car controller of lock housing, lock core is provided with keyhole and this lock core can rotate in lock housing, lock housing is provided with signaling switch and the locking retaining " LOCK " that is connected with signaling switch, startup retaining " ACC " and work retaining " ON ", and lock core can come back rotation respectively in above-mentioned three gears.Signaling switch is connected with entire car controller by three lines, and " ACC " signal and " ON " signal respectively with entire car controller in the MCU chip on " acc " and " on " signal corresponding connection of input pin, the output of entire car controller also is connected with parts such as main drive motor controller, power battery management system, many information displays controller and instrument.
This electric automobile key switch device is when automobile is stopped using, lock core is in " LOCK " shelves, signaling switch sends the locking signal to entire car controller, by sending the whistle control system outage after the entire car controller processing again, parts such as main drive motor controller, power battery management system, many information displays controller, instrument and vehicle-mounted bus are quit work, simultaneously the locking direction dish.
When the car owner uses vehicle, key is inserted in the lock core earlier and rotate with the control lock core, when lock core turns to " ACC " shelves, the triggering signal switch sends the MCU chip of enabling signal to the entire car controller, by its control storage battery 12V power connection, each controller of electric drive system for electric vehicles and car load low pressure annex are started working vehicle-mounted bus initialization.When leaving " ACC " shelves, lock core goes to " ON " when shelves, " ACC " signal interruption, " ON " signal is connected, the triggering signal switch sends working signal to the MCU chip, the storage battery continued power, forceful electric power in the on-board high-voltage system, each onboard system operate as normal of electric automobile is operated the relative response that all can realize system by entire car controller as accelerator pedal and brake pedal.After vehicle is finished using, lock core is gone back to " LOCK " shelves, parts such as main drive motor controller, power battery management system, many information displays controller, instrument and vehicle-mounted bus quit work once more, the steering wheel locking, the car owner can extract key and only just can extract at " LOCK " shelves at this moment.
