The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) behind any car door opening of automobile, car phone will be dialed car owner's mobile phone automatically, sends caution to the car owner, thereby avoids automobile stolen.

Description of drawings

Fig. 1 is the electrical schematic diagram of the utility model.

The specific embodiment

As shown in Figure 1; The cab warning of the utility model; Comprise direct supply B, be installed in contact K1, contact K2, contact K3 and contact K4, DC contactor coil KM, DC contactor normally closed switch KM1, teleswitch KR and car phone on four car doors of automobile respectively; Said contact K1, contact K2, contact K3, contact K4 and DC contactor coil KM are serially connected in the two ends of direct supply B, and said DC contactor normally closed switch KM1, teleswitch KR and car phone C also are connected in series the two ends of direct supply B.

After the car owner is stopped, four car doors of automobile are locked, through remote controller that teleswitch KR is closed then; Just can leave automobile then, at this moment, contact K1, contact K2, contact K3 and contact K4 are closed; Direct current contact coil KM gets electric, and direct current contact coil normally closed switch is opened, and car phone C is in off-position; When people or robber illegally open any car door of automobile, any disconnection in contact K1, contact K2, contact K3 and the contact K4 closure, DC contactor coil KM dead electricity; This moment, DC contactor normally closed switch KM1 was closed, and car phone C is in running order, therefore can put through car owner's phone automatically; Send caution, stolen to avoid automobile.

The cab warning of the utility model, not only simple in structure, rate of false alarm is low, and can send caution to the car owner in the very first time, thereby very easy to use.

The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
