The 1 st gear part 1221 and the 2 nd gear part 1222 function as a gear tooth of a rack gear and a pinion gear engaged to a gear tooth of a door, respectively.
The rack gear 300 is slidably installed at the outside of the air-conditioning case 110. The rack gear 300 is formed in a straight shape to transmit the rotational force of the 1 st shaft 121 to the 2 nd shaft 122. When the rack 300 is formed in a straight shape, it is more advantageous to achieve the transmission of force. The rack gear 300 is engaged to the 1 st shaft 121 at one side and the 2 nd shaft 122 at the other side. The rack 300 functions to link the 1 st shaft 121 and the 2 nd shaft 122.
The 2 nd gear portion 1212 of the 1 st shaft 121 is located inside in the shaft direction than the 1 st gear portion 1211 of the 1 st shaft 121. Meanwhile, the 2 nd gear portion 1222 of the 2 nd shaft 122 is located inside in the shaft direction than the 1 st gear portion 1221 of the 2 nd shaft 122.
A gear tooth 301 is formed on a surface of one side of the rack 300 engaged with the 1 st shaft 121, which is opposite to the 1 st shaft 121, and a gear tooth 302 is formed on a surface of the other side of the rack 300 engaged with the 2 nd shaft 122, which is opposite to the 2 nd shaft 122. The 1 st shaft 121 and the 2 nd shaft 122 are disposed in opposite directions to each other with respect to the rack 300. Thereby, the 1 st shaft 121 and the 2 nd shaft 122 are made to have different rotation directions.
In the air conditioner for a vehicle, when the 1 st door 118 slides by the rotation operation of the controller, the 2 nd door 119 slides in an interlocking manner. The air conditioner for a vehicle includes a cam 220 and an operating lever 210.
The cam 220 is connected to the controller and rotates in the air-conditioning case 110 by a rotating operation. The operating lever 210 is connected to the cam 220 and is rotated in the air-conditioning case 110 by the rotation of the cam 220. The 1 st shaft 121 is engaged with the lever 210 to be rotated and coupled to the 1 st door 118, and the 2 nd shaft 122 is coupled to the 2 nd door 119.
The cam 220 is rotatably provided outside the air-conditioning case 110 about a rotation shaft 221. The cam 220 is connected to the controller via a cable 230, and the cam 220 includes a coupling portion 222 for connecting to the cable 230. The cam 220 is formed with a long hole-shaped slit 223 that slidably guides the pin 211 of the lever 210. When the knob of the controller is rotated, the cam 220 is rotated about the rotation shaft 221 by the cable 230.
The operating lever 210 is rotatably provided outside the air conditioning casing 110 about a rotation shaft 212. A pin 211 is protrudingly formed at the operating lever 210, and the operating lever 210 is coupled to a slit 223 of the cam 220 by the pin 211. A gear tooth 215 engaged with the 1 st shaft 121 is formed at one side surface of the operating lever 210. When the cam 220 rotates, the pin 211 is slidably guided along the slit 223 of the cam 220, and the pin 211 rotates around the rotation shaft 212.
The rack 300 and the operating lever 210 are arranged side by side in the axial direction of the 1 st shaft 121. The 1 st gear 1211 of the 1 st shaft 121 is located outside the air-conditioning case 110 and is engaged with the operation lever 210 and the rack gear 300. That is, the gear teeth 215 of the operating lever 210 and the gear teeth 301 of the rack gear 300 are engaged together to the 1 st gear portion 1211 of the 1 st shaft 121. The rack gear 300, the operating lever 210, and the cam 220 are all disposed outside the air-conditioning case 110. The 2 nd gear part 1212 of the 1 st shaft 121 is located inside the air-conditioning case 110 and is engaged to the gear teeth 1181 of the 1 st door 118. The 1 st door 118 is disposed inside the air-conditioning case 110.
When the operation lever 210 is rotated, the 1 st shaft 121 engaged to the operation lever 210 is rotated, whereby the 1 st door 118 slides inside the air-conditioning case 110 and the rack 300 slides outside the air-conditioning case 110.
The 1 st gear part 1221 of the 2 nd shaft 122 is located outside the air-conditioning case 110 and is engaged to the rack gear 300. The 2 nd gear portion 1222 of the 2 nd shaft 122 is located inside the air-conditioning case 110 and is engaged to the gear teeth 1191 of the 2 nd door 119. The 2 nd door 119 is disposed to the inside of the air-conditioning case 110. When the rack gear 300 slides, the 2 nd shaft 122 engaged with the rack gear 300 rotates, whereby the 2 nd door 119 slides inside the air-conditioning case 110.
Thus, when the controller is rotated, the 1 st shaft 121 and the 2 nd shaft 122 are rotated in opposite directions to each other, and the 1 st door 118 and the 2 nd door 119 are slid in opposite directions to each other.
In addition, the lever 210 and the rack gear 300 are arranged in the axial direction and engaged to the 1 st shaft 121 in a double structure. That is, the lever 210 and the rack gear 300 are engaged in a double structure in the same direction. This prevents the lever 210 and the rack 300 from being disengaged. Referring to fig. 7, the operating lever 210 is disposed on the upper portion of the rack gear 300, and the gear teeth 215 of the operating lever 210 and the gear teeth 301 of the rack gear 300 are simultaneously engaged with the 1 st gear portion 1211 of the 1 st shaft 121.
When considering the characteristics of a temperature-adjusting door having a relatively large size and weight, in the case of a manual type vehicle air conditioner in which the operation of the door is mechanically controlled by the operation of a controller, it is necessary to solve the problem of an increased operational feeling. The air conditioning device for a vehicle of the present embodiment adjusts the gear ratio between the operation lever 210 and the 1 st shaft 121 and the gear ratio between the 1 st shaft 121 and the rack 300 to increase the magnitude of the variable force, thereby improving the operational feeling on the controller side.
In addition, the operation lever 210 and the rack gear 300 are arranged in the axial direction and engaged with the 1 st shaft 121 in a double structure, whereby the rack gear 300 moves in the same direction as the rotation direction of the operation lever 210 to further reduce the operation force applied to the knob of the controller to improve the operation feeling. Meanwhile, the operating lever 210 and the rack 300 are disposed in the same direction and the occupied space can be reduced, so that the size of the air conditioner can be reduced.
Further, the 1 st shaft 121 and the 2 nd shaft 122 are arranged in diagonal directions with reference to the rack 300, and the 1 st door 118 and the 2 nd door 119 slide in opposite directions to each other to open and close the flow path of the air conditioning case, so that the force applied to the doors is divided into 1/2 to contribute to improvement of the operation force, and the entire package size of the air conditioning apparatus can be reduced by applying the sliding door structure.
On the other hand, the 1 st shaft 121 includes gear teeth having different sizes from adjacent gear teeth, and the operating lever 210 and the rack 300 engaged with the 1 st shaft 121 also include gear teeth corresponding thereto. Referring to fig. 5, gear teeth 3011 having a pitch larger than that of adjacent gear teeth are formed on gear teeth 301 on one side of a rack 300. Meanwhile, gear teeth 1215 corresponding to the gear teeth 3011 of the rack bar 300 are formed in the 1 st gear portion 1211 of the 1 st shaft 121, and gear teeth 2155 corresponding to the gear teeth 3011 of the rack bar 300 are formed in the gear teeth 215 of the lever 210.
The 2 nd shaft 122 has gear teeth having a size different from that of adjacent gear teeth, and the rack 300 engaged with the 2 nd shaft 122 also has gear teeth corresponding thereto. The gear teeth 302 on the other side of the rack 300 are formed with gear teeth 3021 having a larger pitch than the adjacent gear teeth. Meanwhile, gear teeth 1225 corresponding to the gear teeth 3021 of the rack gear 300 are formed at the 1 st gear part 1221 of the 2 nd shaft 122.
With this configuration, the rack and the shaft are prevented from being separated from each other, and erroneous assembly is prevented, and the assembly reference point between the shaft and the operation lever and the rack is formed, thereby improving the assembling property.
Although the vehicle air conditioner according to the present invention has been described with reference to the embodiments shown in the drawings, the embodiments are merely illustrative, and those skilled in the art will understand that various modifications and equivalent embodiments of the present invention can be realized. Therefore, the true technical scope of the present invention should be defined according to the technical idea of the appended claims.
