[0054] Embodiment 1

[0055] This embodiment provides an air volume distribution device, which can meet different configuration requirements such as dual temperature zones, triple temperature zones, and quad temperature zones by adding or reducing parts, thereby reducing costs.

[0058] The first damper 210 is slidably disposed at the entrance of the first air inlet channel along the second direction, and is used to adjust the opening of the first cold air channel 111 and the first hot air channel 112. The first damper 210 is provided with a first rack 211 extending along the second direction. The second damper 220 is slidably disposed at the entrance of the second air inlet channel along the second direction, and is used to adjust the opening of the second cold air channel 121 and the second hot air channel 122. The second damper 220 is provided with a second rack 221 extending along the second direction. The third damper 230 is slidably disposed at the entrance of the third air inlet channel along the second direction, and is used to adjust the opening of the third cold air channel 131 and the third hot air channel 132. The third damper 230 is provided with a third rack 231 extending along the second direction. The fourth damper 240 is slidably disposed at the entrance of the fourth air inlet channel along the second direction, and is used to adjust the opening of the fourth cold air channel 141 and the fourth hot air channel 142. The fourth damper 240 is provided with a fourth rack 241 extending along the second direction.

[0059] The first drive shaft 310 is hollow inside, and a first drive gear 311 is provided on the first drive shaft 310, and the first drive gear 311 is meshed with the first rack 211. A second drive gear 321 is provided at one end of the second drive shaft 320, and the second drive gear 321 is meshed with the second rack 221.

The fourth drive shaft 340 is hollow inside, and a fourth drive gear 341 is provided on the fourth drive shaft 340, and the fourth drive gear 341 is meshed with the fourth rack 241. A third drive gear 331 is provided at one end of the third drive shaft 330, and the third drive gear 331 is meshed with the third rack 231. The other end of the third drive shaft 330 is rotatably inserted into the fourth drive shaft 340 and extends out of the fourth drive shaft 340.

[0060] The driving assembly is used to drive the first driving shaft 310, the second driving shaft 320, the third driving shaft 330 and the fourth driving shaft 340 to rotate independently, or to drive any two of the first driving shaft 310, the second driving shaft 320, the third driving shaft 330 and the fourth driving shaft 340 to rotate synchronously.

[0061] The air volume distribution device provided in this embodiment divides the air volume into four temperature zones by arranging a first air inlet channel, a second air inlet channel, a third air inlet channel and a fourth air inlet channel on the shell 100. The first air gate 210, the second air gate 220, the third air gate 230 and the fourth air gate 240 are used to control the air inlet temperatures of the four temperature zones respectively.

[0062] That is, the driving assembly can realize the independent sliding of the first damper 210, the second damper 220, the third damper 230 and the fourth damper 240 by driving the first driving shaft 310, the second driving shaft 320, the third driving shaft 330 and the fourth driving shaft 340 to rotate independently, so as to meet the four-temperature zone configuration requirements. The driving assembly can make any two dampers move in conjunction with each other and the remaining two dampers move independently to meet the three-temperature zone configuration requirements by driving any two of the first driving shaft 310, the second driving shaft 320, the third driving shaft 330 and the fourth driving shaft 340 to rotate synchronously, and the remaining two rotate independently. The driving assembly can make the four dampers move in conjunction with each other to meet the dual-temperature zone configuration requirements by driving any two of the first driving shaft 310, the second driving shaft 320, the third driving shaft 330 and the fourth driving shaft 340 to rotate synchronously, and the remaining two also rotate synchronously, so as to meet the dual-temperature zone configuration requirements. Thus, the air volume distribution device can flexibly realize the dual-temperature zone, three-temperature zone or four-temperature zone configuration according to customer needs, and since most of the parts can be used universally, the cost is greatly reduced.

[0063] Through the nested arrangement of the first drive shaft 310 and the second drive shaft 320, and the nested arrangement of the third drive shaft 330 and the fourth drive shaft 340, on the one hand, the total occupied space of the first drive shaft 310, the second drive shaft 320, the third drive shaft 330 and the fourth drive shaft 340 is reduced, which is conducive to meeting the miniaturized design requirements of the vehicle air conditioner; on the other hand, it is convenient to arrange the drive assembly on the side of the first drive shaft 310 away from the second damper 220, and on the side of the fourth drive shaft 340 away from the third damper 230, which makes the arrangement less difficult and occupies less space.

[0065] It can be understood that when the first damper 210 slides in a direction close to the first cold air passage 111, the opening of the first cold air passage 111 becomes smaller, and the opening of the first hot air passage 112 becomes larger. Similarly, when the second damper 220 slides in a direction close to the second cold air passage 121, the opening of the second cold air passage 121 becomes smaller, and the opening of the second hot air passage 122 becomes larger. When the third damper 230 slides in a direction close to the third cold air passage 131, the opening of the third cold air passage 131 becomes smaller, and the opening of the third hot air passage 132 becomes larger. When the fourth damper 240 slides in a direction close to the fourth cold air passage 141, the opening of the fourth cold air passage 141 becomes smaller, and the opening of the fourth hot air passage 142 becomes larger.

[0066] It is worth noting that, in this embodiment, the first direction is Figure 1 The direction shown by the X axis, the second direction is Figure 1 The direction is shown by the Y axis.

[0067] It can be understood that the first drive shaft 310 , the second drive shaft 320 , the third drive shaft 330 and the fourth drive shaft 340 can all be rotatably mounted on the housing 100 .

[0068] Optionally, first sliding grooves are provided on opposite sides of the first air inlet channel along the first direction, and both sides of the first air door 210 are slidably connected to the two first sliding grooves respectively.

[0069] Optionally, second sliding grooves are provided on opposite sides of the second air inlet channel along the first direction, and both sides of the second air door 220 are slidably connected to the two second sliding grooves respectively.

[0070] Optionally, third sliding grooves are provided on opposite sides of the third air inlet channel along the first direction, and both sides of the third air door 230 are slidably connected to the two third sliding grooves respectively. Such a setting can improve the smoothness and reliability of the sliding of the third air door 230.

[0071] Optionally, fourth sliding grooves are provided on opposite sides of the fourth air inlet channel along the first direction, and both sides of the fourth air door 240 are slidably connected to the two fourth sliding grooves respectively. Such a setting can improve the smoothness and reliability of the sliding of the fourth air door 240.

[0072] Furthermore, in this embodiment, the housing 100 is provided with an air inlet channel, and three partitions are provided in the air inlet channel and are arranged in parallel and spaced apart along the first direction, and the three partitions divide the air inlet channel into a first air inlet channel, a second air inlet channel, a third air inlet channel, and a fourth air inlet channel.
