Abstract
The utility model discloses a safety device for automobiles, relating to an automobile fitting. The utility model comprises an outer housing, a resistance R, a power supply E2, a relay switch K1, a switch K2, a relay J and a horn. After being electrically connected, all of the electric devices are fixed in the outer housing. After the outer housing is arranged on a position around a driver, when an accident occurs and the driver requires for a rescue, the driver can make the horn work and produce sounds through the relay switch K1, so as to prompt passers-by or traffic polices for help.
Description
The utility model relates to a kind of vehicular spare parts, and it is a kind of automobile safety device.
At present the automobilist is in operational process as robbery, passenger when having emergency situation, driver extraordinary circumstances or automobile to occur to break down, and the driver can not utilize a certain parts of automobile to send an SOS to the external world, so can not in time be succoured.
The purpose of this utility model is to provide a kind of automobile safety device, and it can be automobile and driver, the sound gives the alarm when various emergency situation appears in the passenger.
The technical solution of the utility model is such: a kind of automobile safety device, it has shell, resistance R, power supply E
2, relay switch K
1, K switch
2, relay J and loudspeaker, wherein battery is through lead and the relay J that is connected in series, relay switch K
1, K switch
2With loudspeaker and downlink connection, battery is also with loudspeaker and connect and be electrically connected.The two ends of battery are connected with automobile power source E with lead, are connected with resistance R on the connection lead of power supply E and battery.The electric device that connects is fixing in the lump in the enclosure.Leave switch hole on the housing of shell, K switch
2Be installed on the switch hole relay switch K
1Be connected with make and break contact in the shell through shell with lead.
Characteristics of the present utility model are: when the driver meets emergency situation in halfway and when needing emergency, presses relay switch K
1After, relay J is sent electricity to loudspeaker, and loudspeaker are rung often, and causes pedestrian or traffic police's the attention of passing by on one's way, and the driver is succoured timely.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Accompanying drawing 1, automobile safety device structural representation;
Accompanying drawing 2, automobile safety device electrical schematic diagram.
Among the figure: 1 shell, 2 resistance R, 3 batteries, 4 relay switch K
1, 5 K switch
2, 6 relay J, 7 loudspeaker.
As shown: with lead with resistance R 2, battery 3, K switch
25, after relay J 6 and loudspeaker 7 connect by the electrical schematic diagram requirement, resistance R 2, battery 3, relay J 6 are fixed in the shell 1, loudspeaker 7 are fixed on the speaker net hole site of shell 1 K switch
25 are fixed on the switch hole of shell 1, respectively open an aperture at shell 1 two ends, with relay switch K
1Pass the aperture of shell 1 and the J in the shell 1 with line
1Two contacts be connected; Pass a connection lead at another aperture place of shell 1 and be electrically connected with battery 3 and resistance R 2, its shell 1 outer connection lead is connected with the power supply E of automobile.
Automobile power source E is by giving after resistance R 2 step-downs battery 3 chargings, when the driver meets emergency situation need succour the time, presses relay switch K
14, battery 3 positive electrical stream is through K switch
25 and relay switch K
14 get back to negative pole by relay J 6 forms the loop, makes to produce electromagnetic induction in the relay J, makes the contact relay J
1And J
2Closure, J
1Contact closure makes relay J 6 finish electrical equipment self-locking action, J
2Contact closure make loudspeaker 7 must establish by cable the beginning pipe.When finger leaves relay switch K
1After 4, relay switch K
14 revert to normally open automatically, the J and positive electrical is flowed through
1Contact makes circuit keep loop state, thereby works on.After the driver obtains relief, Push switch K
2After 5, cut off the circuit loop state, its J
1J
2Also recover off-state simultaneously, 7 on loudspeaker stop to pipe.
