Abstract
A structure used for high voltage safety protection system when in collision of electric vehicles comprises a battery management system, high-voltage electric equipment, a vehicle controller and controllable electric accessories and is characterized by being further provided with a collision switch. One end of the collision switch is connected with a signal output end of the battery management system, a normally-closed contact of the collision switch is connected with a high-voltage input end of the high-voltage electric equipment, a normally-opened contact of the collision switch is connected with a signal input end of the vehicle controller, and the signal output end of the vehicle controller is connected with the controllable electric accessories. Being arranged at the signal input end of the vehicle controller, the collision switch receives collision signals and cuts off output of high voltage when the vehicles are in collision, so that passengers are protected from being harmed by contacting with the vehicles when short circuit or electric leakage of high-voltage equipment is caused by collision.
Description
Technical field
The utility model relates to a kind of method of electronlmobil high-voltage safety protection system.Particularly relate to a kind of through the structure that electronlmobil collision that an impact switch improves the safety of system high pressure equipment the time is used for the high-voltage safety protection system is set.
Background technology
Along with country continues to increase the input of electronlmobil; The development that electric vehicle engineering makes rapid progress makes people also increasingly high to the safety requirements of automobile; Particularly the output of the voltage of electronlmobil medium power battery has the high pressure output of hundreds of volt sometimes; If can cause great potential safety hazard in case bump, cause second accident easily.
Summary of the invention
The utility model technical matters to be solved is, is used for the structure of high-voltage safety protection system when a kind of electronlmobil collision that makes vehicle very first time cut off high electricity output when bumping is provided.
The technical scheme that the utility model adopted is: a kind of electronlmobil is used for the structure of high-voltage safety protection system when colliding; Include battery management system, high pressure consumer, entire car controller and controllable electrical appliance annex; Also be provided with impact switch; One end of said impact switch connects the signal output part of battery management system; The normally closed contact of described impact switch connects the high-tension current input end of high pressure consumer, and the open contact of described impact switch connects the signal input part of entire car controller, and the signal output part of described entire car controller connects the controllable electrical appliance annex.
The electronlmobil of the utility model is used for the structure of high-voltage safety protection system when colliding, through the signal input part at entire car controller an impact switch is set, and impact switch receives collision alarm when collision happens, breaks off the output of high-tension current.Entire car controller receives the work of all the controllable high-voltage equipment of cut-out of making a response rapidly behind the impact switch signal.Prevent to cause in the collision process short circuit of high-tension apparatus or electric leakage that the personnel that touch vehicle are damaged.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
1: battery management system 2: the high pressure consumer
3: entire car controller 4: the controllable electrical appliance annex
K: impact switch
The specific embodiment
The structure that is used for the high-voltage safety protection system during to the electronlmobil collision of the utility model below in conjunction with embodiment and accompanying drawing is made detailed description.
As shown in Figure 1; The electronlmobil of the utility model is used for the structure of high-voltage safety protection system when colliding; Include battery management system 1, high pressure consumer 2, entire car controller 3 and controllable electrical appliance annex 4; Also be provided with impact switch K, the end of said impact switch K connects the signal output part of battery management system 1, and the normally closed contact of described impact switch K connects the high-tension current input end of high pressure consumer 2; The open contact of described impact switch K connects the signal input part of entire car controller 3, and the signal output part of described entire car controller 3 connects controllable electrical appliance annex 4.
The model that described impact switch K adopts KOSTAL company to produce is the impact switch of 039901xx.
The control method of the structure of high-voltage safety protection system comprised the steps: when the electronlmobil of the utility model collided
1) when bumping, at first cut off and high pressure consumer 2 bonded assembly electrical source of power, battery management system 1 sends the signal of closing all high pressure consumers to entire car controller 3 simultaneously;
When collision happens, the normally closed contact of impact switch breaks off, thereby cuts off and high pressure consumer 2 bonded assembly electrical source of power, and the open contact of impact switch is connected, and the signal output part of battery management system 1 is connected with the signal input part of entire car controller 3.
When 2) entire car controller was received the signal of closing all high pressure consumers, closeall high pressure consumer responded rapidly.
The electronlmobil of the utility model is used for the structure of high-voltage safety protection system when colliding, impact switch is received battery management system, when collision happens; Impact switch receives collision alarm and cuts off electrical source of power rapidly; Battery management system sends the signal of closing all high pressure consumers to entire car controller, and entire car controller receives behind the collision alarm closeall high pressure consumer in the very first time, promptly controls air-conditioning; Warm braw; All high pressure consumers such as motor cut off, and prevent to collide the short circuit that causes and cause that the infringement of equipment is perhaps on fire, thereby equipment and personnel are caused bigger injury.
