Description

[Detailed description of the invention] The present invention relates to a sensitive device for emergency stop in vehicles such as automobiles that use an engine. Specifically, this invention is a sensitive device that automatically turns off the engine when the vehicle body comes into contact with an obstacle such as an object or a human body. be.

Generally, when driving a vehicle such as a car, the starting switch (
The engine is driven and operated by turning the key).
When stopping, it is normal to gradually decelerate and stop by switching the clutch, operating the brake, etc.

However, when driving on the road, you never know when an obstacle will appear, and you are often forced to make an emergency stop.

In this case, even if the driver suddenly applies the brakes to stop the vehicle, it is of no use if the driver is delayed in discovering the obstacle (pedestrian, bicycle, etc.).

In particular, in the case of large vehicles such as trucks, which have recently become a social problem, there has been no means to reduce or eliminate accidents involving pedestrians, bicycles, etc. who enter the driver's blind spot.

The present invention was developed in view of the above-mentioned circumstances, focusing on the great benefit it would bring to those skilled in the art if it were possible to eliminate at least the accidents caused by low-speed driving such as when starting at an intersection or reversing when parking in a garage, etc. It is something.

That is, the present invention includes a group of antenna rods that move when an obstacle such as a human body placed around the outside of the vehicle comes into contact with it, and a relay section that is connected in series with the group of antenna rods, at the stage before the start switch, so that the engine stops when the contact occurs. The drive is automatically cut off and stopped.

Hereinafter, the present invention will be described with reference to drawings of embodiments.

Reference numeral 1 denotes a vehicle body, and a antenna rod 2 having an appropriate length extends over the entire outer circumference of the front, rear, left and right parts of the lower edge of the bumper 1a.
The group is installed horizontally and continuously, and the movable contact 3 attached to the hook-shaped base end 2a of the antenna rod 2 is constantly in contact with the fixed contact 5 provided on the relay housing 4. It becomes a closed circuit.

6 is a pressing spring attached to the back of the movable contact 3.

Reference numeral 2' denotes an arc-shaped antenna rod projecting downward at each front and rear of the wheels 7 arranged on all sides, and a movable contact 3 provided at the base end 2a' of the antenna rod 2' is connected to a spring 6 provided at the back. The movable contacts 3 and the fixed contacts 5 are connected in series with electric wires 8a to form a sensitive circuit 8.

Reference numeral 9 denotes an emergency switch for cutting off the power, which is connected between the battery 10 and the starting switch 11 into which the engine key is inserted, and the switch piece 9a of the switch 9 is connected to the sensitive circuit 8.
The primary current circuit 13 is closed when it is attracted by the electromagnet 12 having one end wrapped around it.

One end of the sensitive circuit 8 is connected to the battery 10 via a diode 14, and the other end is grounded.

Reference numeral 15 denotes an indicator lamp provided in the energization management box 16 that houses the electromagnet 12 and the switch 9.

Reference numeral 15' denotes an indicator lamp attached to the two antenna rods located at the front, rear, right and left corners or the center of the vehicle body 1;
' and the indicator lamp 15 are connected in series to the sensitive circuit 8.

To explain the function of the engine, first, when driving the engine, the emergency switch 9, which is a circuit before the starting switch 11, is activated.
Insert a separate key to open the primary current circuit 13 to the turning start switch 11 side, and also open the sensitive circuit 8.
energized.

When the sensing circuit 8 is energized, the electromagnet 12 is energized and holds the switch piece 9a of the switch 9 in an attracted state.

Moreover, when the sensitive circuit 8 is closed, each indicator lamp 15. 1
5 lights up, so that not only the driver but also outsiders can identify that the emergency stop device is ready to operate.

Next, in this state, when the key is inserted into the starting switch 11 and turned as in the conventional case, the primary current flows to the ignition coil 17 and then to the revulator 18, and at the same time, a two-character current flows from the ignition coil 17 and the engine is driven. It is something that will be done.

Here, an appropriate antenna rod 2 arranged around the outer periphery of the vehicle body 1 is used.
When an obstacle such as a human body collides with the antenna rod 2, the proximal end 2a of the antenna rod 2 located inside the relay housing 4, which is the protruding base end, retreats against the spring 6 due to this load. Part 2
The movable contact 3 located at a is separated from the fixed contact 5 (see FIG. 4A).

That is, one part of the series-connected sensitive circuit 8 opens and becomes an open circuit, so the electromagnet 12 is deenergized and the switch piece 9a returns to its return state, and the single-character current circuit 13 for driving the engine becomes an open circuit, stopping the engine. It shall be.

In addition, if an obstacle gets caught in the wheel 7, the antenna rods 2' placed in front and behind the wheel 7 move, and the base end 2a is moved as described above.
' is pushed open against the spring 6, and the movable contact 3 is separated from the fixed contact 5, and the sensitive circuit 8 is opened.

This emergency switch 9 is a two-stage switch, and if there is a failure in the antenna rod 2 or the sensing circuit 8, the electromagnet 1
If 2 is not possible, the switch piece 9a is forcibly pressed by the second rotation of the key to close the current circuit 13 and maintain the conductive state, so that the engine drive is not disturbed.

As mentioned above, the present invention has antenna rods that are movable around obstacles around the outer periphery of the vehicle body and in front and behind the wheels.
The group of antenna rods is made into a series circuit, with a movable contact at the base end, and the whole forms a sensitive circuit, and an electromagnet part formed at one end of the sensitive circuit serves as an emergency switch piece provided at the front stage of the starting switch. By making it openable and closable, when an obstacle such as a human body or object collides with or gets caught, the antenna rod operates and automatically cuts off the primary current circuit to the engine.
It can prevent personal accidents.

For example, it can prevent a car accident when turning left at an intersection, a collision when reversing when turning into a garage, and especially a hit-and-run crime because the engine stops.

Also, since the engine stops if it hits an obstacle, it will also come to an emergency stop if it comes into contact with objects such as buildings, fences, guardrails, oncoming cars, etc., which helps prevent runaways as well as double or triple rear-end collisions. You can also do it.

Furthermore, since the structure of the present invention is extremely simplified, failures and
It has a structure that can withstand long-term use without causing damage.

Of course, in this case, by selecting the spring pressure of the spring attached to the base end of the antenna rod, it can be made so that it will not operate under loads such as gravel, soil, water particles splashing up, wind pressure, etc.

The device of the present invention can be installed not only in passenger cars as shown in the figure, but also in large vehicles such as trucks and buses, and if necessary, it can also be installed in vehicles such as trains (however, in this case, (turns off the power to the motor).
