Abstract:
A mode switch assembly of an automobile having an impact/load absorbing apparatus includes a housing disposed in a center facia panel in the automobile, a circuit board installed in the housing, in which a switch having a shaft is installed, a support portion for supporting the circuit board to be separated from a predetermined distance from the housing, a knob installed at the shaft to protrude from the center facia panel, and an impact/load absorbing unit for allowing the knob and the shaft to retreat with respect to the center facia panel as part of at least one side of the circuit board or the housing is broken by an impact/load applied to the shaft from the knob.
Abstract:
The present invention relates to an air conditioner for a vehicle that includes: a mode door (130) having a thin plate member (150), which slidably operates inside an air-conditioning case (110) to control the degree of opening of a defrost vent (112), a face vent and floor vents, and a gear shaft, which engages with the thin plate member for operating the thin plate member (150); and constant discharging means (119) disposed at a rail portion of the thin plate member (150) and at a guide part of an air-conditioning case (110) overlapped with the rail portion (155), so that air of a fixed quantity is discharged to side vents of the face vent (113), thereby providing a simple structure and reducing manufacturing costs because the gear holes of the rail portion (155) and the cut portions of the guide portion, which are the constant discharging means, can be used as a constant discharge structure without needing additional structure to constantly discharge air toward the side vent.
Abstract:
A fan and shroud assembly includes a fan has a hub rotating around one shaft and a plurality of blades extending outwardly from the hub, a shroud encompassing the fan to adjust airflow by rotation of the fan, a guide ring portion located at a position where a predetermined gap exists between the shroud and a circumference connecting end tips of the blades so that the fan coupled to the shroud rotates, and a plurality of swirl prevention units integrally formed with the guide ring portion to prevent a motion of vortex proceeding along a circumference connecting end tips of the blades between the guide ring portion and the circumference, each swirl prevention unit having a shape in which the length of a circular arc passing each of the swirl prevention units with respect to the center of the shroud decreases as the arc is closer to the center of the shroud.
Abstract:
The invention provides an air freshener generating apparatus of a vehicle air conditioning system adapted to generate and discharge different sorts of air fresheners filled within a cartridge into an interior of a vehicle. The air freshener generating apparatus of a vehicle air conditioning system includes: a body (100) in which an inlet pipe (103) is communicated with an outlet pipe (104) and on which ball plungers (106) are mounted at intervals on a circumferential surface thereof along circumferential lines on which the inlet pipe (103) and the outlet pipe (104) are located respectively; a cartridge (200) coupled to the body (100) and having at least one partition wall such that at least two air fresheners are filled within spaces defined by the partition wall, the cartridge (200) having through-holes (202) at portions of the cartridge (200) corresponding to the spaces defined by the partition wall; and an actuator (300) configured to rotate the cartridge (200) a predetermined angle. When the cartridge (200) is rotated the predetermined angle, air is supplied through the through-hole (202) facing the inlet pipe (103) such that one air freshener is discharged through the through-hole (202) facing the outlet pipe (104) without being mixed with another air freshener.
Abstract:
The present invention relates to a battery cooling device for vehicles and a method for controlling the battery cooling device, which compactly includes battery heat exchanging means (115) mounted on a battery (110) to cooling the battery in a water cooling type, and a heat exchanger (120), air blowing means (140) and cooling water circulating means (130) connected with the battery heat exchanging means. Operations of the air blowing means (140) and the cooling water circulating means (130) are controlled in such a way as to compare battery temperature, cooling water temperature and inside air temperature of the vehicle with one another, whereby the battery cooling device can enhance efficiency of the battery (110) by properly controlling the battery temperature, reduce power consumption and noise by properly operating the air blowing means (140) and the cooling water circulating means (130), and satisfy necessary inside temperature conditions while cooling the battery using the inside air of the vehicle.
Abstract:
The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor. The present invention comprises a core 210, and a coil 240 installed to the core 210 and formed by winding a unit wire 250. At this time, the unit wire 250 wound on the coil 240 is made of aluminum, and an area ratio R of an inner sectional area M of the core 210 to a cross-sectional area of the unit wire 250 is 400 to 640. According to the present invention as above, since the unit wire 250 used for the coil 240 is made of aluminum with a small specific weight and low price rather than copper, the weight of the field coil assembly 200 is decreased to improve fuel efficiency of a vehicle and decrease a production cost of the field coil assembly 200.
Abstract:
A method for controlling a variable capacity compressor of an air conditioner comprising the steps of: setting a target indoor temperature of a car by a user; sensing and inputting car indoor temperature, car outdoor temperature and solar radiation; calculating a target discharge temperature of a vent, calculating a target evaporator temperature and blower voltage; calculating a control duty of a variable displacement compressor according to the target evaporator temperature; calculating a target evaporator temperature change rate and a blower voltage change rate; determining whether or not a sudden variable condition is constituted by one of the control duty, the target evaporator temperature change rate or the blower voltage change rate; and setting the maximum value of the control duty change rate to an accelerative slew rate (Sc) greater than a basic slew rate (S0) when such a condition is determined.
