Abstract
Air flap opening and closing device of the vehicle that improves the cooling efficiency by adjusting the opening and closing of the air flap as necessary.
Air flap opening and closing device of the vehicle according to the present invention is a front end module 10 is formed separately in the air passage in the horizontal direction in the upper and lower, respectively; An opening 20a is formed to correspond to the air flow path formed in the lower portion of the front end module 10, and rotates around the rotating shaft 22 formed in the horizontal direction to open and close the opening 20a. A flap unit 20 to which an air flap 24 is mounted; And a driving unit 30 for providing power to the air flap 24.
Description
The present invention relates to an air flap opening and closing device of a vehicle, and more particularly to an air flap opening and closing device of a vehicle for controlling the opening and closing of the air flap.
In general, various heat exchange parts such as a radiator, an intercooler, an evaporator, a condenser, and the like for cooling a temperature or controlling a temperature in a vehicle, as well as an engine for driving the vehicle, are embedded in the engine room of the vehicle. The heat exchange fluid flows inside the heat exchange parts, and cooling or heat dissipation is performed through heat exchange between the fluid and the outside air. Therefore, in order for various heat exchange parts inside the vehicle engine room to operate stably, external air must be smoothly supplied into the engine room.
In recent years, in order to improve productivity by reducing the number of parts and processes of a vehicle, a plurality of parts are assembled and modularized.
FIG. 1 illustrates a front end module F in which the
Air flaps are installed on the top and bottom of the front end module (F), respectively. In general, the air flap installed in the upper portion is controlled by the actuator, but the air flap A installed in the lower portion, that is, the opening 5a of the
FIG. 2 is a diagram illustrating a case in which power is applied to the solenoid S to maintain the air flap A mounted on the front end module F in a closed state. When the power is turned on, the power is applied to the solenoid (S) to keep the air flap (A) closed. The solenoid S does not have a function of opening the air flap A, and since there is little wind pressure of the air introduced in the vehicle stop state, the air flap A cannot be opened.
3 is a view showing an open state of the air flap (A). When the speed of the vehicle is more than 30km / h, the air flap (A) is opened by the wind pressure of the incoming outside air.
As such, the air flap A mounted on the lower portion of the conventional front end module can only control the closed state by applying power, and only induces the open state by the wind pressure depending on the vehicle speed. Therefore, the engine is turned on and the flap is always kept closed in the warm-up state. In this state, the cooling performance of the entire vehicle is reduced, such as the amount of air flowing into the flap and the amount of air contacting the cooling module is reduced. There was a problem.
The matters described as the background art are only for the purpose of improving the understanding of the background of the present invention and should not be taken as acknowledging that they correspond to the related art already known to those skilled in the art.
The present invention is to provide a vehicle air flap opening and closing device for controlling the closing, as well as the opening of the air flap mounted on the front end module using a solenoid and a magnet to solve the conventional problems.
Air flap opening and closing device for a vehicle according to the present invention for achieving the above object is a front end module formed separately in the air passage in the horizontal direction, respectively, the upper and lower; A flap unit in which an opening is formed so as to correspond to an air flow path formed in the lower portion of the front end module, and an air flap is mounted to open and close the opening by rotating around a rotation axis elongated in a horizontal direction; And a driving unit providing power to the air flap.
The driving unit has a first solenoid having one end fixedly coupled to the front end module, and one end is inserted into the other end of the first solenoid so as to protrude from the other end of the first solenoid when power is supplied to the first solenoid. The other end includes a plunger having a magnet fixedly coupled to the rotating shaft.
A top bracket fixed to the front end module, and a pair of side brackets extending downward from both ends of the top bracket, wherein the driving part comprises: a first solenoid having one end fixedly coupled to the top bracket; One end is inserted into the other end of the first solenoid and the other end includes a plunger having a magnet fixedly coupled to the rotating shaft so that the first solenoid can protrude from the other end when power is supplied to the solenoid.
The driving unit includes a first solenoid having one end fixedly coupled to the front end module, and a second solenoid having a polarity opposite to the first solenoid and having one end fixedly coupled to the rotation shaft.
A first solenoid fixed to the front end module and a pair of side brackets extending downward from both ends of the upper bracket, the first solenoid having one end fixedly coupled to the upper bracket, and the first solenoid and It includes a second solenoid having polarities opposite to each other and one end fixedly coupled to the rotation axis.
The present invention has the effect of improving the heat exchange efficiency when cooling the vehicle by controlling the opening, as well as the closing of the air flap installed in the lower portion of the front end module due to the above technical configuration.
