BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door mirror assembly with a ventilation device, and a vehicle ventilation system using a pair of left and right door mirror assemblies with a ventilation device.

[0002]

2. Description of the Related Art Generally, when a car is parked, doors and windows are closed to prevent theft and the inside of the car is sealed. Therefore, the room temperature inside the vehicle may rise due to the sunlight, and hot air may be trapped. This is especially true under hot weather in summer. In such a case, when the vehicle is parked again, not only the room temperature inside the vehicle but also the temperature of the seats and the like rises, and the cooler becomes difficult to operate. Therefore, the passenger is very uncomfortable.

As a means for alleviating such discomfort, there is, for example, a ventilation device separately attached to the upper part of the window. This device is a device that allows a fan to rotate and release hot air that has been trapped inside the vehicle to the outside of the vehicle, and can suppress the temperature rise inside the vehicle to some extent during parking and is useful. However, the device additionally attached in this way is obtrusive because it obstructs the field of view, and is also a safety problem. Furthermore, since this device impairs the airtightness inside the vehicle, noise outside the vehicle is easily transmitted during traveling, and this device causes adverse effects such as air resistance and wind noise. Therefore, this device needs to be removed when traveling.

[0004]

SUMMARY OF THE INVENTION Therefore, the technical problem to be solved by the present invention is that it is not necessary to specially prepare and install a dedicated part, and the vehicle is parked without any adverse effect during traveling. An object of the present invention is to provide an automobile door mirror assembly and an automobile ventilation system capable of performing ventilation in a vehicle.

[0005]

Means for Solving the Problems and Actions / Effects The present inventors have solved the above technical problems based on the idea of incorporating a ventilation device into a door mirror assembly.

That is, the door mirror assembly according to the present invention is such that a stay having a pedestal portion for being fixed to a door and a projecting portion projecting from the pedestal portion, and a mirror case rotatably engaged with the projecting portion. It has and.
The stay has a ventilation passage that penetrates the pedestal portion and the projecting portion and communicates with the inside and outside of the vehicle. A sliding contact surface that is formed at the tip of the overhanging part of the stay and is in sliding contact with the inner sliding contact surface of the mirror case. When the mirror case is in the use position, it faces the inner sliding contact surface of the mirror case, and the mirror case is retracted. The vehicle exterior ventilation opening of the ventilation passage is provided on the sliding contact surface that is exposed when in the position. The in-vehicle ventilation opening of the ventilation passage of the stay faces the door opening formed in a part of the door to which the pedestal of the stay is fixed. A fan case that covers the door opening is provided inside a part of the door, and the fan case has a ventilation opening, and a ventilation device that blows air toward the vehicle outside ventilation opening inside the fan case. And the ventilator is driven by a drive circuit including a drive switch. The drive switch is turned on when the mirror case is in the retracted position to drive the ventilation device.

In the above structure, when the mirror case is tilted down and stored when the vehicle is parked, the ventilation device operates. At this time, the vehicle-side ventilation opening of the ventilation passage that penetrates the inside of the stay is exposed, and the air inside the vehicle is exhausted from there. In the case of long-time parking that requires ventilation inside the vehicle, the mirror case of the door mirror assembly is generally stored in a collapsed state. Therefore, no special operation is required just to activate the ventilation system.

On the other hand, since the mirror case is not tilted during normal driving, the exterior ventilation opening of the stay exposed when the mirror case is tilted is covered by the inner sliding contact surface of the mirror case. Therefore, the airtightness inside the vehicle is not impaired,
In addition, intrusion of rain or dust from outside the vehicle can be prevented. Further, the door mirror assembly having the above-described configuration can have an external shape similar to that of a general door mirror assembly when in the use position so as not to newly cause adverse effects such as air resistance and wind noise.

Further, the door mirror assembly having the above construction may be always attached. That is, it does not have to be removed during traveling. In addition, by incorporating the related parts into the door mirror assembly and unitizing them, it is possible to assemble the same as a conventional door mirror assembly in a vehicle assembly line without performing new work such as wiring.

That is, the door mirror assembly having the above-described structure does not require specially prepared special parts to be attached thereto, and can ventilate a parked vehicle without adversely affecting it during traveling.

In the above structure, the ventilation device is provided in the fan case. However, the fan case may be eliminated and the ventilation device may be provided in the ventilation passage formed in the stay.

That is, in the path of the ventilation passage of the stay, there is provided a ventilation device for blowing air toward the ventilation opening outside the vehicle, and the ventilation device is driven by a drive circuit including a drive switch. The drive switch is turned on to drive the ventilation device when the mirror case is in the retracted position.

In the above structure, the number of parts can be reduced, so that the manufacturing and assembling costs can be reduced.

Preferably, in addition to the above configuration, a solar battery is further provided on the outer surface of the mirror case as a power source of a drive circuit for driving the ventilation device. With this configuration, a special device for supplying electric power to the ventilation device is unnecessary. Generally, the stronger the solar radiation, the greater the temperature rise inside the vehicle, and the more ventilation is required. At such times, the solar battery has a large electromotive force. Therefore, electric power can be efficiently supplied to the ventilation device when necessary.

In the above construction, when the air inside the vehicle is exhausted, the outside air is normally taken in through the dashboard section. That is, the outside air may be a natural inhalation type.
However, ventilation is not efficient with this natural inhalation method.
Therefore, according to the present invention, there is further provided a ventilation system in which a pair of left and right mirror assemblies having the above-mentioned main parts are used to suck in the outside air from one mirror assembly and exhaust the air inside the vehicle from the other mirror assembly. To be done.

That is, in the vehicle ventilation system according to the present invention, the pair of door mirror assemblies fixed to the left and right doors of the vehicle respectively have ventilation passages penetrating the inside of the door mirror assembly and incorporating the ventilation device. . Each ventilation passage has a pair of ventilation openings,
One ventilation opening faces a door opening formed in a part of the door to which the door mirror assembly is fixed, and the other ventilation opening opens outside the vehicle. The ventilation device of one door mirror assembly is configured as an exhaust unit that exhausts the air inside the vehicle, and the ventilation device of the other door mirror assembly is configured as an outside air suction unit that sucks outside air into the vehicle.

In the above structure, it is not necessary to newly provide a special outside air intake port for ventilation, and the left and right door openings and the door mirror assembly cooperate with each other to achieve efficient ventilation.

Further, a rotary switch 8 which is a drive switch of a ventilation device is provided on a shaft (not shown) provided on the projecting portion 1b of the stay 1, and is turned on when the mirror case 2 is in the storage position II, and other It turns off in the state of.

The motor 5 is driven by the electric circuit shown in FIG. That is, the solar battery 6, the main switch 9, the rotary switch 8, and the motor 5 are connected in series, and the solar battery 6 and the Zener diode 12 are connected in parallel. The main switch 9 is provided inside the vehicle to prevent the motor 5 from operating when ventilation is not needed, such as in winter or at night. The voltage applied to the motor 5 is controlled by the Zener diode 12 so as not to exceed a certain value. When both the rotary switch 8 and the main switch 9 are turned on, the motor 5 operates and the fan 4 rotates.

In the above structure, when the main switch 9 is on and the mirror case 2 is tilted and stored during parking, the air inside the vehicle is ventilated. That is, since the mirror case 2 is in the storage position II, the rotary switch 8 is turned on and the motor 5 operates. At this time, the vehicle exterior ventilation opening 21 of the overhanging portion 1b of the stay 1 is exposed. The fan 4 is rotated by the operation of the motor 5, and the air inside the vehicle is sucked from the ventilation port 22 ′ of the fan case 3,
