Vent assembly with hinged grill unit for automobiles

Abstract

The object of this invention is to provide a vent assembly with a hinged grill unit for automobiles. In this vent assembly 'A', the grill unit (1) consists of a grillwork (11), and a grillwork holder (10) holding the grillwork (11) therein. Two hinge shafts (15) are provided at the holder for acting as a hinging means for hinging the grill unit to the housing. A drive member (3) is provided at a lower portion of the holder at a position vertically aligned with the hinge shafts (15), and engages with a reduction gear (32) of a motor (33) installed in the dashboard 'B'. This grill unit (1) is rotatably set in the housing by the hinge shafts such that the grill unit is rotated around the shafts relative to the housing by a power of the motor transmitted to the drive member (3) through the reduction gear.

Description

technical field [0001] This invention relates generally to ventilation devices for use in ventilating hot and cold air into the interior of a motor vehicle for the purpose of air-conditioning the passenger compartment; more particularly to ventilation devices for motor vehicles having hinged grille units operated at a Or under the operation of the switch, it rotates relative to the housing within a predetermined angle range, thereby allowing the user to selectively open the housing when cleaning the grid unit and the inside of the housing. The ventilation device of the present invention also provides containers for containing desired substances, such as fragrances, and the air filter is detachably fixed in the slot of the grid unit, so that the ventilation device can keep fresh, clean and fragrant Air is blown into the cabin. Background technique [0002] As is known to those of ordinary skill in the art, most automobiles typically have an air conditioning unit, such as a h...

Problems solved by technology

[0008] However, a problem with the aforementioned ventilation nozzles is that when the ventilation channel needs to be opened, the user must manually pull or push the grille, turning the hinged grille relative to the grille frame fixed in the ventilation channel of the dashboard

Therefore, the opening or closing action of the grid piece cannot be performed smoothly

In addition, the user, when trying to open the ventilation passage, may inadvertently touch the grille with his / her fingers, and the grille is heated very hot by the hot air of the heater in winter

In this case, the user is afraid of the hot grille, so the ventilation nozzles are inconvenient for the user

Since the grille of the ventilation nozzle is designed to be manually rotated by the user relative to the grille frame, the hinges of the grille may be subject to excessive stress loads when the user turns the grille about the hinges

In such cases, the hinge may be damaged or broken, forcing the user to replace the damaged or broken part with a new one, thus wasting a great deal of time

Therefore, this ventilation nozzle is inconvenient for the user and forces the user to pay excessive money for new parts

Another problem with vent nozzles of this manually operated configuration is that it undesirably devalues ​​expensive luxury vehicles.
