Abstract

PROBLEM TO BE SOLVED: To protect a human body from static shock when a person gets off an automobile when a door in the automobile is internally mounted with a nonconductive material.SOLUTION: An automobile includes an electric conduction material body 1 which is electrically communicated with an electric conduction vehicle body section 32 on a surface in the vicinity of a sill of an inner window of the automobile. When a person gets off the automobile, electric charge is neutralized and extinguished while bringing his finger to push and open a door 3 into contact with the electric conduction material body, thereby protecting the human body from static shock.SELECTED DRAWING: Figure 1

Description

    An automobile that protects the human body from electrostatic shock by getting off the vehicle while touching the conductive material attached near the lower frame of the door's inner window.

The phenomenon that causes an unpleasant electrostatic shock to the human body occurs remarkably under dry weather conditions where the moisture is low and the water vapor, which should be uncharged due to the static electricity charged, is not in the air.
Under these meteorological conditions, when the automobile door is made of a non-conductive material such as synthetic resin, high-voltage static electricity generated by friction between the seat on the vehicle body and the human body clothing when getting off the vehicle. Is separated from the positive and negative electrodes on the human body side and the car body side when getting off and separated, and is charged for a while, so that a discharge phenomenon occurs between the fingertip on the human body side and the outside of the door when getting off and closing the door May cause unpleasant electrostatic shock to the human body.

    Most of the car casings are made of conductive materials such as iron and serve not only as a strong structure but also as an electrical ground. The positive and negative polarity of the battery that stores the direct current generated by the motor One of the poles is attached to the chassis, or to the vehicle body conductive part that is in electrical communication with the chassis, and the other pole is distributed and wired through each electrical device of the vehicle body, and then attached to each nearby vehicle body conductive part. When it is unnecessary, it is shut off by each switch in the middle of wiring.

    Similarly, the vehicle body conductive part such as the outside of the door such as an iron material that is in electrical communication with the housing may serve as a ground side for the discharge phenomenon when static electricity is generated due to friction with the human body side.

    As mentioned above, the cause of unpleasant electrostatic shock to the human body is that high-voltage static electricity generated by friction when getting off the vehicle is charged to the human body side by the interior of the non-conductive material, and the door of the car is closed from the outside. This is because a discharge phenomenon occurs between the fingertip and the outside of the door.

    A screw that penetrates the conductive material body that is attached to the interior of the interior resin resin near the lower frame of the door of the automobile door and overlaps with the hand that pushes the door open. Fix at least one location.

    As the conductive material body, an electric conductor such as a plate-like, film-like or rod-like metal or carbon that opens a through-hole having a diameter through which the screw can pass is selected.

    The screw is a metal that passes through the through hole of the conductive material body, fits and tightens into a fitting hole that opens in the conductive vehicle body part of the underlying door metal part, and fixes the conductive material body, and also conducts high-voltage static electricity And carbon materials are made to withstand electricity.

    Or, conversely, the screw of the material is a bolt-shaped part that fits into the fitting hole from the back surface of the conductive vehicle body portion of the door and protrudes through the top surface, and further penetrates through the interior non-conductive material and conductive material body. The upper part may be fixed with a nut.

    Then, in order to open the door, the user gets off the vehicle and separates it while touching the conductive material body that is electrically connected to the conductive vehicle body through the screw and is grounded.

    If the conductive material is superposed on the non-conductive material with an adhesive instead of screws, there is no route for inducing high-voltage static electricity to the vehicle body conducting part on the ground side, and static electricity shock will occur.

On the other hand, if the screw penetrates more than one part of the conductive material body, the screw will not be deteriorated when there is no body conductive part on the ground, so only the purpose of fixing the conductive material body on the non-conductive material The screws may be replaced with other materials.
Also, if there is no base body conductive part near the lower frame near the inner window of the door, both ends or one end of the conductive material body is extended to the window's window standing frame, and then the end with the through hole is raised, and the screw penetrates The conductive material body is fixed by fitting tightly into a fitting hole that penetrates the hole and opens to the conductive vehicle body portion of the standing frame.

    As described above, if the human body is in contact with or connected to the conductive material body near the lower frame near the window when getting off the vehicle, the human body communicates with the vehicle body conductive portion and is also on the ground electrode side, and the charge is medium. Since it disappears, it becomes an automobile that protects the human body from electrostatic shock.

    In addition, if the door of a truck is painted in a semi-conducting state, such as a truck door, etc., the fingertip that opens the door communicates with the grounding electrode as described above, and static electricity is not generated. It may not occur.

    An embodiment of the present invention will be described with reference to FIGS.

    A sufficient length including the position where the hand touches the door 3 to open the door 3 along the door glass 31 on the inner window lower frame surface of the door 3 of the automobile, which is built with the non-conductive synthetic resin material 2. A conductive metal plate 1 having a through-hole 11 having a diameter through which a stainless steel screw 5 having resistance to electric resistance can be passed is overlapped near both ends, and the through-hole 11 of the metal plate 1 and a relatively soft synthetic resin material 2 are passed through. Then, if the screw 5 is fitted and fixed in the fitting hole 321 opened in the door metal base portion 32 of the base, the screw 5 comes into contact with the through hole 11 and the fitting hole 321, and the metal plate 1 and the door 3 which is a conductive vehicle body portion are electrically communicated with each other so as to have the same polarity.

    As a result, if the fingertip that pushes the door down comes out of the vehicle in contact with the metal plate 1, the human body is also in contact with the body conduction part and is also on the ground electrode side when the seat and clothes rub against each other. It is neutralized and does not occur, eliminating static electricity when the door 3 is closed, and becomes a car that protects the human body.
