Detailed Description
Hereinafter, the technical structure of the air conditioner for a vehicle will be described in detail with reference to the accompanying drawings.
Fig. 3 is a sectional view showing an air conditioner for a vehicle according to an embodiment of the present invention.
As shown in fig. 3, a vehicle air conditioning device 100 according to an embodiment of the present invention includes an air conditioning case 110, a blower, and a plurality of doors. The air conditioning casing 110 is provided with a cooling heat exchanger and a heating heat exchanger in this order in the air flow direction. The doors are provided in the air conditioning case 110 to adjust the opening degree of the air flow path, and are composed of 1 st and 2 nd doors 118 and 119, which are temperature adjusting doors, and mode doors 115, 116, and 117.
The cooling heat exchanger is constituted by an evaporator 102 that cools air by exchanging heat between the refrigerant in the refrigerant circuit and the air, and the heating heat exchanger is constituted by a heater core 103 that heats air by exchanging heat between the air and cooling water in a cooling water line circulating through the engine. The heating heat exchanger is constituted by a heat exchanger utilizing condensation heat of the heat pump system, an electrically driven PTC heater, and the like.
The 1 st door 118 and the 2 nd door 119 are provided in the air conditioning case 110 to adjust the opening degree of the air flow path. In the present embodiment, the 1 st door 118 and the 2 nd door 119 are arranged to be spaced apart from each other in the vertical direction, and are each constituted by a temperature adjustment door. The temperature adjustment door adjusts the opening degrees of an air flow path passing through the heater core 103 as a heating heat exchanger and an air flow path bypassing the heater core 103.
An air flow inlet 111 is formed on an inlet side of the air conditioning case 110, and a defrost vent 112, a blow-out vent 113, and a floor vent 114, the opening of which is adjusted by the mode doors 115, 116, and 117, respectively, are formed on an outlet side. The blower is connected to an air inlet 111 of the air conditioning case 110 to perform a function of sending out the inside air or the outside air. The evaporator 102 and the heater core 103 are sequentially provided inside the air conditioning casing 110 in the air flow direction.
The temperature adjustment doors (1 st door and 2 nd door) are provided between the evaporator 102 and the heater core 103, and adjust the opening degrees of a cool air flow path bypassing the heater core 103 and a warm air flow path passing through the heater core 103, thereby adjusting the temperature of the air discharged into the vehicle interior. The cold air and the hot air having passed through the cold air flow path and the hot air flow path are mixed in the stirring area and then selectively discharged into the vehicle interior through the respective vents.
Another vehicle air conditioning device 100 according to an embodiment of the present invention is an example in which two doors, i.e., the 1 st door 118 and the 2 nd door 119, are provided as temperature adjustment doors. In this way, the example in which the two temperature adjustment doors are provided at the upper and lower sides is applicable to a structure in which conditioned air is sent to the vehicle rear seat side, a 2-layer structure in which inside air and outside air are separated and introduced into the vehicle interior, and the like.
The vehicle air conditioner 100 includes a shaft. The shaft is rotatably provided in the air-conditioning case 110, and is connected to the door to drive the door by rotation. The shaft is composed of a 1 st shaft 200 connected to the 1 st door 118 to slide the 1 st door 118 by rotation and a 2 nd shaft 200' connected to the 2 nd door 119 to slide the 2 nd door 119 by rotation.
Fig. 4 is a plan view showing a shaft according to an embodiment of the present invention, fig. 5 is a front view showing the shaft according to the embodiment of the present invention, fig. 6 is a view showing a shape of a concave groove according to a modification of the present invention, fig. 7 is a view showing "a" of fig. 4 in an enlarged manner, and fig. 8 is a longitudinal sectional view taken along a line B-B of fig. 5.
In the following description, the 1 st axis 200 and the 2 nd axis 200' are referred to as "axes 200", and the 1 st door 118 and the 2 nd door 119 are referred to as "doors".
Referring to fig. 4 to 8, the door is constructed in a sliding door type that slides inside the air-conditioning case 110 according to the rotation of the shaft 200. The door is formed in a thin plate shape having a predetermined thickness, and a gear portion that meshes with the shaft 200 is formed on one surface. The shaft 200 is rotated by the power source, and the door slides as the shaft 200 rotates.
At least one recessed groove 230 is formed at the shaft 200. The shaft 230 is composed of a shaft portion 220 and a pair of gear portions 210 formed on both sides of the shaft portion 220 in the axial direction. The gear portion 210 is engaged with a gear portion of the door. In the present embodiment, the recessed groove 230 is formed in plural and in a row at a constant interval along the axial direction. A recessed groove 230 is formed between the pair of gear parts 210. The recessed groove 230 is formed in the outer circumferential surface of the shaft portion 220 of the shaft 200 so as to be recessed toward the center in the radial direction.
The opening of the recessed groove 230 is formed in a polygonal shape in a longitudinal section. As shown in fig. 6, the recessed groove 230 is formed of a hexagon a, a quadrangle b, a triangle c, or another polygon. The polygonal shape is structurally stable and greatly improves the rigidity of the shaft 200. Meanwhile, the recessed groove 230 can save material of the shaft 200 corresponding to the recessed volume, and can also reduce the weight of the shaft while performing a reduction function.
In particular, the recessed groove 230 is preferably formed in a hexagonal shape. On the other hand, fig. 9 and 10 are plan views showing the shaft of the modification of fig. 4, and the recessed groove 230 may be formed in a square shape or a triangular shape, but is most preferably formed in a hexagonal shape.
The hexagonal shape provides a strong support structure such as a honeycomb structure, and is structurally more stable than other polygons such as a quadrangle and a triangle, and the rigidity of the shaft 200 can be greatly improved. Further, as shown in fig. 6, since the hexagonal recessed groove has a larger area than the quadrangular and triangular recessed grooves, the weight reduction effect and the rigidity reinforcing effect can be more effectively obtained.
The recessed groove 230 is formed in a groove shape recessed from the outer circumferential surface of the shaft portion 220 of the shaft 200 to a certain depth. That is, the recessed grooves 230 are each recessed to a certain depth, and are advantageous in terms of the rigidity of the shaft as compared with the penetrating shape. In this case, when the recessed grooves are formed in the shape of both sides of the shaft portion penetrating the shaft, although the weight reduction effect is slightly increased, the weight reduction effect is slightly decreased here, and the recessed grooves are formed in a recessed groove shape, so that the rigidity is greatly improved.
Preferably, a recessed groove 230 is formed on both one surface and the other surface of the shaft portion 220 of the shaft 200. More specifically, the recessed groove 230 is formed in a zigzag shape at positions of one surface and the other surface of the shaft portion 220 of the shaft 200 that are opposite to each other in the axial direction and are offset from each other. Referring to fig. 8, the recessed grooves 230 are formed at both sides of the shaft part 220, and the recessed groove 230 of one side and the recessed groove 230 of the other side are formed at different positions from each other in the axial direction without facing each other.
In this way, the recessed grooves 230 are formed in the shaft 200 to be staggered up and down, so that the bottom surface of the recessed groove 230 of one side is positioned at the protrusion (relatively protruded portion) of the other side, thereby supplementing rigidity, and the recessed grooves 230 are formed at both sides, thereby improving the reduction effect and obtaining the weight reduction effect 2 times.
In addition, as shown in fig. 7, the hexagonal-shaped recessed groove 230 is formed in a regular hexagonal shape. The hexagon of the recessed groove 230 includes a 1 st corner 231, a 2 nd corner 232, a 3 rd corner 233, a 4 th corner 234, a 5 th corner 235, and a 6 th corner 236. In this case, the 1 st corner 231 and the opposite 4 th corner 234 are arranged in a direction parallel to the radial direction. That is, the 1 st corner 231 and the 4 th corner 234 are arranged in the direction perpendicular to the axial direction. With such a configuration, stress concentrated in the corner portion is dispersed, and a stronger rigidity effect can be obtained.
On the other hand, fig. 11 is a perspective view showing a part of a shaft of one embodiment of the present invention, fig. 12 is a side view of the shaft of one embodiment of the present invention, and fig. 13 is a cross-section along the line C-C of fig. 11.
Referring to fig. 11 to 13, a hollow hole 225 is formed in the shaft portion 220 of the shaft 200. Preferably, the hollow hole 225 is not formed to entirely penetrate in the axial direction of the shaft 200, but is formed only on the end portion side of the shaft 200 where the gear portion is formed. The cross section of the hollow 225 is formed in a polygonal shape. Preferably, the cross-section of the hollow 225 is formed in a hexagonal shape. The hollow 225 increases the rigidity of the shaft portion 220 of the shaft 200 and reduces the material corresponding to the volume of the hollow 225, thereby achieving a weight reduction effect.
Meanwhile, the reduction groove 211 is formed at the gear portion 210 to improve rigidity and contribute to a weight reduction effect. The reduction grooves 211 may be radially formed in plural numbers around the shaft portion 220.
By forming the hollow 225 into a hexagonal shape, the honeycomb-shaped support structure which is most stable in structure is provided as in the hexagonal shape of the recessed groove described above, and the weight reduction effect is improved by exerting a larger reduction effect than the triangular or quadrangular shape.
