Background
Generally, an air conditioning device for a vehicle, which is a device for cooling or heating a vehicle interior by heating or cooling in a process of introducing air outside the vehicle into the vehicle interior or circulating the air in the vehicle interior, is equipped with an evaporator for performing a cooling action, a heater core (heater core) for performing a heating action, and blowing mode switching shutters that selectively blow air cooled or heated by means of the evaporator or the heater core to respective portions in the vehicle interior, inside an air conditioning case.
Fig. 1 is a sectional view illustrating the interior of a conventional air conditioner for a vehicle. As shown in fig. 1, the conventional air conditioner for a vehicle includes an air conditioning case 30, an evaporator 10, a heater core 20, and a temperature adjustment shutter 32.
The air-conditioning case 30 is provided with a defrost vent (defrostevent) 34, a face vent (face vent)36, and a floor vent (floor vent)38, which are sequentially provided on the downstream outlet side in the air flow direction and are opened and closed by the mode shutters 34d, 36d, and 38d, respectively. The evaporator 10 is built in the air-conditioning case 30 on the inlet 31 side, and the heater core 20 is provided behind the evaporator 10 in the air flow direction.
The temperature adjustment shutter 32 is provided between the evaporator 10 and the heater core 20 and adjusts the opening degree of the air blowing passage on the heater core 20 side or the air blowing passage on the heater core 20 side, thereby performing a function of adjusting the temperature of the blown air, and is provided inside the air conditioning case 30. A blower is provided on the inlet 31 side of the air conditioning casing 30.
The air conditioner for a vehicle configured as above blows inside air or outside air into the inside of the air conditioning case 30 by the blower according to the air suction mode, the air is converted into cold air by heat exchange with the refrigerant flowing inside the evaporator 10 through the evaporator 10, or converted into hot air by heat exchange with the cooling water flowing inside the heater core 20 through the heater core 20, and then discharged into the vehicle compartment through the vent opened according to the cooling mode or the heating mode, thereby performing cooling/heating of the vehicle compartment.
The conventional air conditioner for a vehicle is assembled to a vehicle body in a state of a cabin module of the vehicle, and a console side cover is assembled to a vehicle interior (inline). In this case, a separate fixing device is required to completely assemble the console side cover and prevent movement after assembly. For this reason, a separate Holder (Holder) is required to be formed in the air-conditioning case. Therefore, providing a special bracket leads to an increase in cost.
In addition, in the air conditioner for an electric vehicle, since the wiring is rubbed against the floor of the vehicle body when the air conditioner is mounted in the vehicle body, a separate high-voltage positive temperature coefficient thermistor (PTC) wire protective cover needs to be provided, and the bracket portion and the PTC wiring portion overlap each other.
Disclosure of Invention
In order to solve the above-described conventional problems, the present invention provides an air conditioner for a vehicle having an improved air conditioner case fastening structure capable of simultaneously performing a bracket function and a PTC wire protection cover function.
An air conditioning device for a vehicle according to the present invention is provided with an electric heater that is heated by electric energy and serves as a heating heat source for heating inside an air conditioning case, wherein a protective cover that protects a wiring portion of the electric heater is provided, and a fastening portion for fastening to a console side cover is integrally formed on the protective cover.
In the air conditioning device for a vehicle according to the present invention, the fastening portion is integrally formed at the protective cover, thereby simultaneously performing a function of protecting the wiring portion of the electric heater and a function of a bracket for assembly of the console side cover. Therefore, the protective cover for performing two functions is integrally formed in the lower portion of the air conditioning casing having a narrow space, and thus, the required space is reduced and the number of parts is reduced.
In addition, the slit solves the problem that the product becomes larger along with the integration of the fastening part with the protective cover and the deformation is weaker in the injection molding process of the product. That is, the slit forms a split structure on one side of the fastening portion, thereby improving rigidity against deformation and maintaining dimensional accuracy.

As shown in fig. 2 to 8, the air conditioner for a vehicle according to an embodiment of the present invention includes an air conditioning case 110, a heat exchanger for cooling, a heat exchanger for heating, and a temperature adjusting shutter.
An air inlet of the air conditioning case 110 is provided with a blowing unit including a blower impeller and a blower motor to selectively receive inside air and outside air. The cooling heat exchanger and the heating heat exchanger are provided in this order in the air flow direction of the air conditioning case 110. The air outlet of the air-conditioning case 110 is provided with a defrost vent 111, a face vent 112, and a floor vent 113, which are opened and closed by the respective mode shutters.
The temperature control shutter is provided inside the air conditioning case 110, is disposed between the cooling heat exchanger and the heating heat exchanger, and controls the temperature of the air discharged into the vehicle interior by adjusting the amount of air passing through the heating heat exchanger and the amount of air bypassing the heating heat exchanger.
The air conditioner for a vehicle is a device installed in an electric vehicle, and includes an electric heater 130. The electric heater 130 is heated by electric energy and used as a heating source inside the air conditioning case 110, and may be configured by a PTC heater or the like that generates heat by a PTC element. The heating heat exchanger may be formed of the electric heater 130 or may be formed by adding the electric heater 130 to a separate heat exchanger.
An air conditioning device for a vehicle according to an embodiment of the present invention is provided with a protective cover 200. The protective cover 200 is fastened to the air-conditioning case 110 by another object, and a fastening portion 210 for fastening to a vehicle body is integrally formed on the protective cover 200. The fastening part 210 functions as a Holder (Holder).
Further, a tolerance absorbing member is formed in the fastening portion 210. A slit (slit)211 is formed by opening a groove on the side where the fastening portion 210 is provided. The main function of the tolerance absorbing member is to prevent deformation when the fastening portion 210 is injection-molded, and in addition to this, in the case where the fastening portion 210 is fastened to the vehicle body, the elastic portion function is performed, thereby also performing a function of improving assemblability according to an assembly tolerance together.
The protective cover 200 performs a function of protecting the wiring portion 131 of the electric heater 130. A fastening portion 210 for fastening to the console side cover 300 is integrally formed at the protective cover 200.
The air conditioner for a vehicle is installed in a vehicle body in a cockpit module state, and a console side cover 300 is assembled in a vehicle interior (inline). The fastening part 210 performs a fixing function such that movement does not occur after the console side cover 300 is accurately assembled and assembled to the air-conditioning case 110. The protective cover 200 may include an electrical component cover, a wire cover, an actuator cover, and the like.
The protective cover 200 is fastened to a lower portion of the air-conditioning case 110. The protective cover 200 is formed with a fastening groove 205 for fastening with the air-conditioning case 110. The upper end surface 207 of the protective cover 200 is fixed by a screw or the like through the fastening groove 205 in a state of being in close contact with the lower end surface of the air-conditioning casing 110. The protective cap 200 is recessed to form a predetermined space therein, and is opened at an upper portion thereof in a substantially U-shape.
The fastening part 210 is formed at a side surface of the protective cover 200. The fastening portion 210 includes a support portion 212, a shaft portion 213, and a disk portion 214. The support portion 212 is formed on a side surface of the protective cover 200 to protrude in a disc shape from the side surface of the protective cover 200 in a lateral direction. The shaft portion 213 is formed in a disk shape and protrudes laterally from the support portion 212. The disk portion 214 is formed in a disk shape and is formed to protrude from the shaft portion 213 in the radial direction.
A vehicle body 400 is disposed at a lower portion of the air-conditioning case 110, and the wiring portion 131 of the electric heater 130 provided at the air-conditioning case 110 is rubbed against a bottom surface of the vehicle body 400. The protective cover 200 covers a part of the lower portion of the air-conditioning case 110, and the protective cover 200 is disposed between the air-conditioning case 110 and the bottom surface of the vehicle body 400. The protective cover 200 prevents the wiring portion 131 of the electric heater 130 from directly contacting the bottom surface of the vehicle body 400.
The disk part 214 of the fastening part 210 is slidably inserted into a fastening part 310 formed at the console side cover 300, so that the console side cover 300 is fixed to the protective cover 200. The fastening portion of the console side cover 300 is formed with a rail portion 315 having a shape of "Contraband", and is slid as the disk portion 214 is inserted into the rail portion 315, thereby completing the assembly.
Finally, the fastening part 210 is integrally formed at the protective cover 200, thereby simultaneously performing a function of protecting the wiring part 131 of the electric heater 130 and a function of an assembling bracket of the console side cover 300. In this way, the protective cover for performing both functions is integrally formed in the lower portion of the air conditioning casing having a narrow space, and thus, the required space is reduced and the number of components is reduced.
The fastening portion 210 is formed with a slit 211 having a groove opened at one side. The slits 211 are formed in the fastening portion 210 to extend in the radial direction. More specifically, the slit 211 is formed to extend downward from the upper end surface of the protective cover 200 through the support portion 212, the shaft portion 213, and the disk portion 214. The slit 211 extends to the center of the support portion 212, the shaft portion 213, and the disk portion 214.
That is, the Slit 211 forms a Slit (Slit) shaped split structure from the upper end surface 207 of the protective cover 200 toward the lower portion. In this case, the slit 211 may be extended only to the center of the fastening part 210 to maintain strength. When the slit 211 extends beyond the center of the fastening part 210, the strength of the fastening part 210 is sharply reduced.
The slit 211 solves the problem that the product becomes large and is easily deformed when the product is injection-molded as the fastening portion is integrated with the protective cover. That is, the slit 211 forms a split structure at one side of the fastening part 210, thereby improving strength against deformation and maintaining dimensional accuracy.
In other words, the slit 211 provides a split structure at one side of the fastening part 210. The groove portion of the slit 211 provides stronger structural strength against deformation such as bending or flexing of the fastening portion 210 if the slit 211 is provided, compared to a fastening portion in a disk shape in which no slit is formed.
In addition, fig. 9 is a sectional view showing a separated state of the protective cover and the console side cover according to the modification of fig. 8.
Referring to fig. 9, a wedge-shaped protrusion 330 having a larger cross-sectional area and a smaller cross-sectional area is formed on the console side cover 300. The fastening portion 210 is formed with an insertion hole 230 having a smaller diameter toward the inner side so as to be inserted into the boss portion 330. By inserting the boss 330 into the insertion hole 230, the console side cover 300 is easily assembled to the protective cover 200.
In addition, according to a modification of the present invention, the tolerance absorbing member may be formed using a rubber material or the like and formed outside the injection-molded fastening part 210 by double injection molding. The rubber sufficiently performs a tolerance absorbing function while improving airtightness between the fastening portions. Since leakage may occur in the case where a watertight structure is required, the slits of the above-described embodiment may be formed of a rubber member that can achieve both the tolerance absorbing function and the watertight function.
Although the air conditioner for a vehicle according to the present invention has been described above with reference to the embodiments shown in the drawings, the description is merely exemplary, and those skilled in the art will understand that various modifications and other equivalent embodiments can be made. Therefore, the true technical scope should be defined by the technical idea described in the claims.
