Abstract

The utility model relates to an alarm device for prompting a driver and passengers of a motor vehicle to fasten safety belts, which is composed of a power supply of a motor vehicle starter, a sounder, a seat cushion contactor of a double-metal head and a double-metal clamping sheet of a safety belt bayonet; the sounder, the seat cushion contactor and the safety belt bayonet are connected in series by an electric wire; both ends of the electric wire are connected to the power supply of a motor vehicle starter to form a closed circuit. When users gets on the vehicle and sit down, two contactors of the seat cushion contactor are pressed and contacted to close; at this time, if people do not fasten the safety belt, two metal clamping sheets of the safety belt bayonet are in a contact and closed state; after the vehicle is started, a circuit is communicated so that the sounder sends out sounds to prompt people to fasten the safety belt. After the users fasten the safety belt and belt heads are inserted in the safety belt bayonet, the belt heads enable the two metal clamping sheets to separate; the circuit is off and the sounder stops working.

Description

Automobile safety belt prompt alarm device

Technical field

The utility model belongs to self-propelled vehicle safety fittings technical field, relates to a kind of alarm device that is used to point out automobile driver and passenger's system of disposition safety strap.

Background technology

Require chaufeur and relevant occupant (mainly being the front passenger's seat person of taking advantage of) system of disposition safety strap during self-propelled vehicle is set out on a journey and travelled, this is the important behave that ensures driver and conductor's personal safety.But reality is the custom that has appreciiable driver and conductor all not fasten the safety belt when driving or ride, and the interior safety strap facility of car is performed practically no function, and does not have due effect; Though self can consciously fasten the safety belt the driver who has, often forget and remind the passenger to fasten the safety belt that these phenomenons bring greatest hidden danger for undoubtedly driver and conductor's personal safety.

The utility model content

The purpose of this utility model is to provide at above-mentioned present situation a kind of simple in structure, easy for installation, the automobile safety belt prompt alarm device that can be supervised prompting to driver and conductor's system of disposition safety strap situation.

The technical solution that is used to realize the foregoing invention purpose is such: the automobile safety belt prompt alarm device that is provided has one by vehicle launch device power supply, rattler, composite metal headstock pad contactless switch and composite metal intermediate plate safety strap bayonet socket are formed close circuit, wherein the positive terminal of actuator power supply connects with a contact of seat cushion contactless switch through rattler, another contact of seat cushion contactless switch is connected on the safety metal intermediate plate with bayonet by electric wire, the negative pole end of safety another metal intermediate plate with bayonet and power supply links, two contacts of seat cushion contactless switch are contained in the upper and lower that a pair is arranged on the insulated spring in the cushion respectively, after the human body seat is pressed on the insulated spring, two contact contacts are closed, make circuit turn-on.In the practical application, with rattler, seat cushion contactless switch and safety strap bayonet socket are together in series successively with electric wire, the end of a thread two is terminated on the motor vehicle starting device power supply, after chaufeur or passenger loading are sitting on the seat, two contacts of seat cushion contactless switch are subjected to the press contacts closure, if this moment is chaufeur and/or passenger system of disposition safety strap not, then constitute safety two metal intermediate plates with bayonet and be in the contact closure state, start vehicle (energized) even the back circuit turn-on, rattler is started working, send the speech sounds alarm such as " note that and fasten seat belts " etc., prompting chaufeur and/or passenger fasten one's safety belt; When chaufeur and passenger all be with safety strap health and will take the lead to insert the safety strap bayonet socket after, take the lead to make two metal intermediate plates of bayonet socket to separate, circuit disconnects, rattler quits work.The back is when starting vehicle if the user fastens the safety belt earlier, and then rattler is not worked.

Of the present utility model simple in structure, easy to use, cost is low, is easy to install to use, it has solved in the past effectively in the car there is and no problem the safety strap facility, system of disposition safety strap drops to potential safety hazard minimum when constantly reminding the driver and conductor to drive a vehicle.Adopt sound-producing device in car because this installs in addition, thereby car is not constituted noise outward yet.

Description of drawings

Accompanying drawing is the structural representation of a specific embodiment of the utility model.

The specific embodiment

Referring to accompanying drawing, automobile safety belt prompt alarm device described in the utility model is made up of vehicle launch device power supply 1, rattler 2, composite metal headstock pad contactless switch 3 and composite metal intermediate plate safety strap bayonet socket 4, the positive terminal of actuator power supply 1 connects with a contact of seat cushion contactless switch 3 through rattler 2, another contact of seat cushion contactless switch 3 is connected on the metal intermediate plate of safety strap bayonet socket 4 by electric wire, another metal intermediate plate of safety strap bayonet socket 4 and the negative pole end of power supply 1 link, and constitute close circuit with this.Recorded the prompt alarm sound in the rattler 2.Seat cushion contactless switch 3 by a secondary insulated spring 5 and two contacts constitute, wherein insulated spring 5 is made up of two springs and two insulcretes that are crimped on both ends of the spring, two contacts are contained in the upper and lower of insulated spring 5 respectively, after human body was sat on the insulated spring 5 that is pressed in the seat, two contact contacts were closed.
