Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile having an electrode plate provided inside a door for gradually discharging to prevent an electrostatic shock and having a monitor for confirming the discharge attached thereto. The present invention relates to a static eliminator with a monitor.

[0002]

2. Description of the Related Art An electrode plate is formed on a handle inside a vehicle according to Japanese Patent Laid-Open No. 61-36024.
It is well known that a device having a relatively large resistance value is interposed between the electrode plate and the body to perform discharge without electrostatic shock.

[0003]

As a result, when a passenger grips the door handle when getting off the vehicle, static electricity is removed, but if the contact with the handle is incomplete, other door parts may be touched. Or you will get an electrostatic shock after getting off.

In view of the above points, an object of the present invention is to provide a static electricity eliminator with a monitor of an automobile capable of confirming discharge of static electricity.

[0005]

In order to achieve this object, the present invention is provided, according to claim 1, on the inside of a door so that a passenger's hand comes into contact therewith, and prevents an electrostatic shock. A static electricity eliminator with a monitor attached to a conductive electrode plate connected to the body via a large resistance that can be gradually discharged like this, with a monitor attached to confirm that static electricity has been discharged. Switching means for performing a switching operation that generates a switching signal or opens and closes a circuit in response to a positive or negative electrostatic voltage that is supplied from the electrode plate and that exceeds a predetermined level that requires discharge, and makes it visible to the rider. Light emitting means for emitting light, and light emission for generating a light emission signal of a predetermined time width which is longer than the normal discharge time and visible in response to the switching operation And No. generating means, characterized by comprising a light emitting driving means for driving the light emitting means in response to the emission signal.

When the passenger's hand touches the electrode plate,
Corresponding to the resistance between the bodies, the discharge is gradually performed so as not to give an electrostatic shock, and if the positive or negative electrostatic voltage exceeds a predetermined level, the light emission signal generating means responds to the switching operation of the switching means. Generates a light emission signal that is longer than the normal discharge time and has a visually recognizable predetermined time width, during which the light emission drive means drives the light emission means to emit light.

BEST MODE FOR CARRYING OUT THE INVENTION A static electricity removing device with a vehicle monitor according to an embodiment of the present invention will be described with reference to FIGS. In FIG. 3, reference numeral 3 denotes a pull handle arranged on the upper surface of an armrest 2 provided in a door trim 1 on the interior side of the vehicle door. As shown in FIG. 2, a conductive electrode plate 7 is provided on the side wall surface of the interior of the pull handle, and an LED 14 with a lens is attached to the front flange portion 3a of the vehicle as a light emitting means. . Further, a circuit housing portion 6 for monitoring is formed below it, and a connector 8 of a wire harness 8a having a power supply line from a battery and a body wire can be connected to the bottom surface thereof.

As shown in FIG. 1, the circuit accommodating portion 6 is connected to an electrode plate 7 and has a resistance value large enough to be gradually discharged, including resistance to the body, so as to prevent electrostatic shock. The series resistors R1 and R2, and the switching means 10 that receives the divided voltage and outputs a switching signal in response to the input of + or-electrostatic voltage, and in response to the switching signal, for example, several seconds. A light emitting signal generating means 12 for generating a light emitting signal having a time width of 1 and a light emitting driving means 13 for driving the LED 14 in response to the light emitting signal are housed.

The operation of the static eliminator with a monitor constructed as described above is as follows. When the passenger grips the pull handle 3 with his / her hand when getting off the vehicle, the charged + or − static electricity flows from the electrode plate 7 to the body through the resistors R1 and R2. At that time, the discharge is performed with the discharge time constant including the resistors R1 and R2 and the resistors thereafter, so that the spark is not generated and the occurrence of the electrostatic shock is suppressed.

At the same time, when a divided voltage of a predetermined level generated in the resistor R2 is input to the switching means 10 with respect to an electrostatic voltage of a voltage level that is subject to electrostatic shock,
A switching signal is output regardless of its polarity. As a result, the light emission signal generation means 12 outputs a light emission signal having a pulse width of, for example, a few seconds which is longer than the normal discharge time and is visible, and the light emission drive means 13 lights the LED 14 during that time. As a result, the occupant can confirm the discharge of static electricity, and can release the vehicle with peace of mind by releasing the hand after the LED 14 is turned off.

FIG. 4 illustrates a more specific monitor embodiment. For example, + electrostatic voltage exceeding a predetermined level (see FIG.
(A) is generated in the electrode plate 7, the switching means 17 performs a switching operation to turn on during that level, and the battery 16 supplies the power supply voltage to the power supply capacitor C1 (see FIG.
B) is charged, and the reverse current is blocked by the reverse current blocking diode D2.
1 is applied to the collector. On the other hand, the voltage for light emission signal is charged in the capacitor C2 through the backflow prevention diode D1. As a result, the capacitance of the capacitor, the base resistor R3, and the resistor R4 that looks large according to the current amplification factor.
The base current of the transistor TR1 (FIG. 5C) is supplied for several seconds with a time constant defined by and the LED 14 is driven by the amplified current. The LED 14 is turned off while gradually dimming over a longer period of time as the discharge is completed, that is, when the switching means 17 is turned off, thereby ensuring a reliable discharge. As switching means, product name 74LS
An equivalent operation can be performed using the IC No. 04 and the like.

[0012]

According to the first aspect of the present invention, static electricity is removed without a shock when the electrode plate of the door is contacted, and when the light emitting means is turned off and the hand is released, a complete discharge is achieved. Can be confirmed. According to the second aspect of the invention, when the pull handle is gripped when getting off the vehicle, the static electricity is automatically removed without shock, and the discharge can be confirmed by looking at the LED on the upper peripheral surface.
