Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body vent hole structure applied to a vehicle having a door such as a truck or a passenger car.

[0002]

2. Description of the Related Art A vehicle body having a door such as a cab of a truck or a passenger car is provided with a vent hole for the purpose of improving the opening / closing property of the door.

9 to 11 show a conventional ventilation hole structure provided in a cab of a truck. A door inside ventilation hole 2 is opened in a trim portion of a door 1 on a vehicle interior side, and a surface outside the vehicle interior is further shown. A door outer vent 3 is opened on the lower surface of the door 1. Normally, the inside air vent 2 of the door is designed in consideration of the appearance, and the air inside the vehicle, which is compressed when the door 1 is closed and the atmospheric pressure is increased, flows into the hollow part 4 of the door from the inside air vent 2 of the door, and It is discharged to the outside of the vehicle compartment through the door outside ventilation hole 3. In FIG. 10, 5 is a cab, and 6 is a weather strip provided between the cab 5 and the door 1.

The ventilation holes having the above-described structure are provided in the left and right doors 1, respectively, and are used not only for improving the opening / closing property of the door 1 but also as an exhaust port for ventilation. It should be noted that similar vent holes are also provided in passenger cars, but in this case, they are generally arranged at a proper position in the rear part of the vehicle compartment rather than the door.

[0005]

By the way, the opening area of the vent hole may be made as large as possible if the door opening / closing property and the function as the ventilation exhaust port, which are the purpose of installing the vent hole, are merely improved. However, the above-described conventional ventilation hole is always open, and therefore, there is a disadvantage that the efficiency of the air conditioner is deteriorated when the opening area is increased, and traveling noise and engine noise are more likely to enter the vehicle interior. For this reason, it is necessary to consider conflicting circumstances when determining the opening area of the ventilation hole, and as a result it is not possible to secure a sufficient size to achieve good door opening / closing performance. .

Therefore, an object of the present invention is to provide a vent hole structure for a vehicle body which can achieve both improvement of door opening / closing performance and efficiency improvement of an air conditioner.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a vent hole which is formed in a panel forming a vehicle compartment to communicate the inside of the vehicle interior with the outside of the vehicle interior. However, the air vent structure of the vehicle body is provided with a lid member that opens and closes in conjunction with the half door detecting means.

In the vent hole structure, a permanent magnet is fixed to the lid member that is swingably mounted, and an electromagnet that is mounted on the vehicle body side and is energized by a signal from the half door detecting means is used. The permanent magnet may be attracted or repelled to open and close the lid member, or
The lid member mounted swingably or slidably is connected to driving means, and the driving means operated by a signal from the half-door detecting means swings or slides the lid member to open and close. May be.

Further, the lid member is characterized in that the vent hole is opened when the door is opened, and the vent hole is closed when the door is closed. Even if a switch for manually opening and closing the lid member is provided in the vehicle compartment. Good.

[0010]

According to the above-described means of the present invention, since the vent member is provided with the lid member interlocking with the half-door detecting means, the vent hole is opened when the door is open, and the vent hole is opened when the door is closed. The lid member can be automatically opened and closed to close it.

When the electromagnet energized by the signal from the half door detecting means acts on the swingable lid member to which the permanent magnet is fixed, both magnets attract or repel depending on the polarity. Therefore, the lid member swings, and the vent hole can be opened / closed in conjunction with the opened / closed state of the door.

Alternatively, a lid member that is swingably or slidably mounted is connected to a driving means, and when the driving means is activated by a signal from the half-door detecting means, the lid member swings or slides to open and close the vent hole. It can be operated.

By opening the ventilation hole when the door is opened and closing the ventilation hole when the door is closed, the air in the passenger compartment whose atmospheric pressure rises due to the operation of closing the door is smoothly discharged from the opened ventilation hole to the outside of the vehicle. Also, when operating the air conditioner with the door closed, the ventilation hole is closed to improve efficiency.

Further, when the lid member is opened during traveling by a manual switch operation, the open ventilation hole can be used as an exhaust port for ventilation.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a vent hole structure for a vehicle body according to the present invention will be described below with reference to the drawings.

In the first embodiment shown in FIG. 1, the lid member 7 is attached to the door outside vent hole 3 among the vent holes made up of the door inside vent hole 2 and the door outside vent hole 3 provided in the door 1. is there. The lid member 7 is a resin plate material, and one end of the lid member 7 is swingably attached to a door component member via a hinge 8. At the other end of the lid member 7, a metal piece 9 attracted by the magnet is fixed to the upper surface side, and a permanent magnet 10 is further fixed to the lower surface side. On the other hand, a first electromagnet 11 is attached to the outer peripheral portion of the door outer vent hole 3 at a position where it comes into contact with the permanent magnet 10 at the fully closed position, and further, to a resin bracket 12 projectingly provided in the door hollow portion 4. Is a metal piece 9 in the fully open position.
The second electromagnet 13 for adsorbing is attached. In this case, the polarities of the contact surfaces of the permanent magnet 10 and the electromagnets 11 and 13 should be set such that the permanent magnet 10 and the first electromagnet 11 repel each other and the second electromagnet 13 attracts the metal piece 9 when energized. Good. For example, if the permanent magnet 10 is set to the N pole, the first electromagnet 11 when energized also becomes the N pole, and the second electromagnet 13 may be set to the S pole. The position of the second electromagnet 13 may be set so that the angle at which the lid member 7 swings and falls due to its own weight when the energization is released and the attraction force is lost is the fully open position. Reference numeral 14 in FIG. 1 indicates a seal member.

An example of an electric circuit for the above-mentioned electromagnets 11 and 13 will be described with reference to FIG. 2. Reference numeral 15 is a power source, 16 is a half-door warning switch attached to the door 1 as a half-door detecting means, and 17 is a A half-door warning light that informs an occupant in the passenger compartment of the opening / closing state of the door, 18 is a manual switch that allows the occupant to manually open and close the lid member 7, 19 is the half-door warning switch 16 or the manual switch 18 is OFF. )
Electromagnets 11, 1 until a predetermined time has passed since
3 is a delay circuit that keeps the power supplied to 3. In this circuit, the manual switch 18 is normally in the off position, and the half-door warning switch 16 is turned on when the half-door and the door are opened to turn on the half-door warning lamp 17. Further, when the half-door warning switch 16 is turned on, the electromagnets 11 and 13 are also brought into conduction with the power supply 15. As a result, the first electromagnet 11 exhibits the polarity of the N pole and repulsively pushes up the permanent magnet 10 of the N pole as well, and at the same time, exhibits the polarity of the S pole.
Since the metal piece 3 attracts the metal piece 9, the lid member 7 is
0 and the first electromagnet 11 come into contact with each other to swing from the fully closed state in which the door outer vent 2 is closed to the fully opened state in which the second electromagnet 13 adsorbs the metal piece 9. In this state, the inside of the vehicle compartment and the outside of the vehicle compartment communicate with each other through the door inner air vent 2, the door hollow portion 4, and the door outer air vent 3 as flow paths.

When the door 1 is closed while the lid member 7 is fully opened, the half-door warning switch 16 is turned off and the half-door warning lamp 17 is turned off immediately before the door 1 is fully closed. Then, after a predetermined delay time (about 1 second) has passed since the half-door warning switch 16 was turned off, the energization of the electromagnets 11 and 13 is stopped and the polarity is lost, so that the lid member 7 is fully loaded by its own weight. Swing to the closed position and fall. Then, the air in the passenger compartment whose air pressure is increased by closing the door 1 is smoothly discharged to the outside of the passenger compartment through the door outside air vent 3 which is maintained in the fully opened state even during the delay time, so that the door 1 is closed. In that case, the resistance can be reduced. Further, when the door 1 is closed, the door outside vent hole 3 is also in the fully closed position, so that the air in the air-conditioned interior of the vehicle can be prevented from flowing out of the vehicle. Further, since the door outside vent hole 3 can be fully opened by operating the manual switch 18 even when the door is closed, the vent hole can be positively used as a ventilation exhaust port according to the occupant's preference.

The above-described air vent structure of the vehicle body can be modified in various ways other than the first embodiment shown in FIG. For example, a plate-shaped rubber is used instead of the resin lid member 7 which can be swung by the hinge 8, and one end of the rubber is fixed to the outer periphery of the door outside ventilation hole 3, and the other end is provided with the metal piece 9 and the first piece.
The electromagnet 10 may be fixed. In addition, the resin lid member 7
A rubber may be used in place of the hinge 8 that allows swinging.

In FIG. 3 showing the second embodiment, the lid member 7 is supported by a guide member 20 so as to be linearly slidable, and as shown in FIGS. 5 and 6, an electric motor 21 or a linear motor 22 or the like is used. It is configured to be connected to the driving means and to be opened / closed by a signal from the half door detecting means. In the case of FIG. 5 in which the electric motor 21 is used as the driving means, the nut member 23 is fixed to the lid member 7 and is screwed with the screw member 24 that is rotated by the driving force of the electric motor 21 fixed to the vehicle body side. The member 7 slides to open and close. Linear motor 2
6, the linear motor 22 is fixed to the lid member 7 so that both slide integrally with the guide rail 25.

In FIG. 4 showing the third embodiment, a substantially semi-disc shaped lid member 7 is slidably supported by a guide member 20 and is connected to a driving means of an electric motor 21 as shown in FIG. The air vent is opened and closed by a signal from the half door detecting means.

FIG. 8 shows an example in which an electric motor 21 is used as a drive means for the swingable lid member 7.
The electric motor 21 is connected to the lid member 7 via a speed reducer 25.

In each of the above embodiments, an electric motor is used as the drive means, but in the case of a vehicle having a compressed air supply source such as a large truck, an air motor may be used instead of the electric motor. It is possible.

Further, although the door is suitable for the truck cab as the position for providing the above-described ventilation hole structure, especially for passenger cars, it is not possible to install the ventilation hole having the same structure at a proper position in the rear part of the passenger compartment. Needless to say.

[0025]

According to the present invention described above, since the lid member that opens and closes in conjunction with the half-door detecting means is provided in the vent hole for communicating the inside and outside of the vehicle compartment, the vent hole is automatically opened by the lid member when the door is closed. Therefore, the opening area of the ventilation hole can be set large without considering deterioration of efficiency of the air conditioner. Further, since this cover member automatically opens the ventilation hole when the door is opened, the air compressed in the vehicle interior by the operation of closing the door is discharged to the outside of the vehicle through the ventilation hole having a sufficient opening area, and therefore the smoothness is ensured. You can open and close the door easily.

Further, when the door is normally closed, the lid member closes the ventilation hole to maintain the efficiency of the air conditioner. However, when using ventilation for simply introducing the outside air for ventilation, the ventilation hole is opened by operating the manual switch. It can also ventilate efficiently.
