Description
Technical field
The present invention and a kind of device ensureing automotive safety, particularly relate to one and automatically terminate device for automobile door lock during automobile chance water.
Background technology
Along with the development of society, increasing people has automobile, but along with the continuous increase of automobile quantity, all kinds of security incidents of automobile emerge in an endless stream, particularly after vehicle water falling, the security incident caused because occupant can not escape in time in car occurs repeatedly, thus brings huge loss to society and family, and therefore the security performance of automobile is more and more subject to people's attention.Under normal circumstances, each car door of automobile has an electromagnet for opening, locking a door, according to right-hand screw rule, change electromagnet current direction and can change electromagnet magnetic direction, automobile door lock control module is exactly realize unblanking and locking a door with the sense of current that this principle changes electromagnet; When being automatically locked more than 40km/h arrangements for automotive doors after automobile starting, automobile power source short circuit may be caused when water logging met by automobile, manually cannot open car door by unlock button, cause in the stranded car of passenger, cannot escape.In order to prevent to occur this type of accident, reduce casualties, at present, some invention also just improves automotive electric glass window, but due to window area less, passenger climbs out of difficulty comparatively greatly from window, and the safety that passenger escapes cannot ensure.
Summary of the invention
The present invention manually cannot open car door by unlock button for solving when marine insurance met by automobile, cause in the stranded car of passenger, the problem that cannot escape, provide a kind of automobile chance water valve lock and automatically terminate device, when water met by automobile, door lock automatically terminates, and ensures passenger safety escape.
The technical scheme that the present invention takes is: a kind of automobile is met water valve lock and automatically terminated device, and comprise lithium battery, immersion probe and relay, the both positive and negative polarity that the both positive and negative polarity of lithium battery carries charging module respectively by wire and automobile connects; Lithium battery and automobile carry coupled in series diode between charging module; Lithium battery is 12V lithium battery.Relay coil positive pole is connected by immersion probe Chang Kaiduan and lithium battery anode, and relay coil negative pole directly and cathode of lithium battery connection; The normally closed terminal of relay two and stationary end are connected on automobile doo lock motor two ends respectively, and the stationary end of relay two Chang Kaiduan is connected in automobile doo lock motor two ends respectively, and the adhesive end of relay two Chang Kaiduan and the two ends of relay coil connect.Directly and the connection of lithium battery positive and negative electrode, two of immersion probe is often opened terminal series-shunt and is connected between lithium battery anode and relay coil positive pole for the positive and negative electrode of immersion probe two power supply terminal; Immersion probe is 12V immersion probe, and immersion probe has one or more, when having more than one, and multiple immersion probe parallel connection.
Beneficial effect of the present invention: when water full car short circuit met by automobile, car door lock can be removed instantaneously under effect of the present invention, then manual unlocking car door, passenger just can escape at once, solves existingly to escape length consuming time and unsafe problem from glass window; The present invention only directedly can give the electric discharge of car door lock electromagnet under the effect of diode, and can not discharge to charging equipment for automobile; The present invention causes lithium battery short circuit after being coupled in circuit by relay normal-closed end substring and can preventing automobile electric from meeting water short circuit on the way; Design circuit of the present invention is simple, and required spare part cheapness is easily purchased.
