Description

[Detailed Description of the Invention] The present invention relates to a device that alerts the user in the event that the person leaves the vehicle without closing the ashtray provided in the interior of the vehicle.

Generally, if you forget to close the ashtray inside the car and leave the car, there is a possibility that the cigarettes inside will smolder. 55-128599). However, in order to completely eliminate the cause of smoldering caused by forgetting to close the ashtray, it is still desirable to close the ashtray before exiting the vehicle.

The present invention has been made to solve this problem, and it is possible to close the ashtray of a car by warning only when it is necessary to warn about forgetting to close the ashtray, thereby preventing the occurrence of a fire. The purpose is to provide a forgetting alarm device.

Therefore, in the present invention, a first switch that detects the open state of the ashtray, a second switch that detects the stopped state of the engine, and a third switch that detects the open state of the side door are provided. We have installed an alarm that activates when all switches 1, 2, and 3 are in the detection state, so that if you forget to close the ashtray when you stop the engine and try to get out of the car, you will not forget to close the ashtray. I'm trying to warn you.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments.

In the drawing, 1 is a battery, 2 is battery 1
2, an ignition switch having a common fixed contact connected to the positive pole of the battery 1; 3, a chamber as an alarm connected to the positive pole of the battery 1 without going through the ignition switch 2; 4, an oscillator for driving the chamber 3; this oscillator 4 includes an oscillator 5 and an npn-type transistor 6 for driving the chamber, which is turned on and off by the oscillator 5; the oscillator 5 is driven under the conditions described below; and one of the four side door switches F, R, F, L, R, R, R, and L is turned on and off by the oscillator 5.
When one of them is turned on, chamber 3 is driven to generate an alarm.

That is, the oscillator 4 includes an AND circuit 7 for driving the oscillator 5, and one input terminal 7a of the AND circuit 7 is connected to an ashtray that turns on when an ashtray (not shown) in the room is opened. An open detection switch 8, a light switch (not shown) connected by a line 9, and a keyless switch 10 for detecting the presence or absence of a key are connected in parallel via a diode 11, while the other input terminal 7b is The ACC contact of the ignition switch 2 is connected via the inverter 12.

Therefore, when the ignition switch 2 is now switched from on to off and the ACC contact is turned off, the other input of the AND circuit 7 becomes "H",
When at least one of the ashtray open detection switch 8, the light switch, and the keyless switch is on, one input also becomes "H", and the output of the AND circuit 7 becomes "H" and starts driving the oscillator 5.

During driving of the oscillator 5, when at least one of the side door switches F, R, F, L, R, R, R, and L is turned on, that is, when at least one side door is opened, the transistor 6
The emitter side is grounded, and is intermittently driven by the oscillation wave from the oscillator 5 to drive the chain 3 and issue an alarm.

In the figure, reference numeral 13 is a speed switch, which drives the chain 3 to generate a continuous sound when the vehicle speed exceeds 100 km/h, for example.

With the above configuration, the ashtray open detection switch 8 serves as the first switch to detect the open state of the ashtray, the ignition switch 2 serves as the second switch to detect the stopped state of the engine, and the third switch serves as the open state of the side door. When at least one of the side door switches F, R, F, L, R, R, R, and L that detects the state is in its respective operating state, that is, when the ashtray inside the car has been forgotten to close, When you turn off the ignition switch 2 and open the side door to exit the vehicle, the chimney 3 is activated and issues an alarm, alerting the occupants so that they know that the ashtray has been left open. be able to.

As is clear from the above explanation, in order to prevent smoldering caused by forgetting to close the ashtray, the present invention generates an alarm when the engine is stopped and the driver attempts to exit the vehicle. An object of the present invention is to provide a warning device for forgetting to close an ashtray for an automobile, which achieves the above object without causing any hindrance to normal use.

Furthermore, the present invention can also be used as a device that can alert you when you forget to close the ashtray by simply adding a switch that detects the open state of the ashtray to the conventional warning system installed in automobiles. It can be implemented easily and inexpensively.

Incidentally, in the above embodiment, a chime was used as the alarm, but it goes without saying that other devices such as a buzzer, an alarm lamp, etc. may be turned on.
