[0055] Example 1

[0056] This embodiment provides an air volume distribution device that can meet different configuration requirements such as dual temperature zones, triple temperature zones, and quad temperature zones by adding or removing parts, thereby reducing costs.

[0057] Specifically, if Figure 1-Figure 4 As shown, the air volume distribution device includes a housing 100, a first damper 210, a second damper 220, a third damper 230, a fourth damper 240, a first drive shaft 310, a second drive shaft 320, a third drive shaft 330, a fourth drive shaft 340 and a drive assembly.

[0058] The housing 100 is provided with a first air inlet channel, a second air inlet channel, a third air inlet channel, and a fourth air inlet channel arranged in sequence along a first direction. The first air inlet channel includes a first cold air channel 111 and a first hot air channel 112 arranged opposite each other along a second direction. The second air inlet channel includes a second cold air channel 121 and a second hot air channel 122 arranged opposite each other along the second direction. The third air inlet channel includes a third cold air channel 131 and a third hot air channel 132 arranged opposite each other along the second direction. The fourth air inlet channel includes a fourth cold air channel 141 and a fourth hot air channel 142 arranged opposite each other along the second direction.

[0059] A first damper 210 is slidably disposed at the entrance of the first air inlet channel along the second direction 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 in the second direction. A second damper 220 is slidably disposed at the entrance of the second air inlet channel along the second direction 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 in the second direction. A third damper 230 is slidably disposed at the entrance of the third air inlet channel along the second direction 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 in the second direction. A fourth damper 240 is slidably disposed at the entrance of the fourth air inlet channel along the second direction 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 in the second direction.

[0060] The first drive shaft 310 is hollow in interior and is provided with a first drive gear 311, which meshes with the first rack 211. A second drive gear 321 is provided at one end of the second drive shaft 320, which meshes with the second rack 221. The other end of the second drive shaft 320 is rotatably inserted through the first drive shaft 310 and extends out of the first drive shaft 310. The fourth drive shaft 340 is hollow in interior and is provided with a fourth drive gear 341, which meshes with the fourth rack 241. A third drive gear 331 is provided at one end of the third drive shaft 330, which meshes with the third rack 231. The other end of the third drive shaft 330 is rotatably inserted through the fourth drive shaft 340 and extends out of the fourth drive shaft 340.

[0061] The drive assembly is used to drive the first drive shaft 310, the second drive shaft 320, the third drive shaft 330 and the fourth drive shaft 340 to rotate independently, or to drive any two of the first drive shaft 310, the second drive shaft 320, the third drive shaft 330 and the fourth drive shaft 340 to rotate synchronously.

[0062] 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 door 210, the second air door 220, the third air door 230 and the fourth air door 240 are used to control the air inlet temperature of the four temperature zones respectively.

[0063] Specifically, the drive assembly independently rotates the first, second, third, and fourth drive shafts 310, 320, 330, and 340 to achieve independent sliding of the first, second, third, and fourth dampers 210, 220, 230, and 240, thereby meeting four-zone configuration requirements. By synchronously rotating any two of the first, second, third, and fourth drive shafts 310, 320, 330, and 340, while allowing the remaining two to rotate independently, the drive assembly can achieve linkage between any two dampers, while allowing the remaining two to move independently, thereby meeting three-zone configuration requirements. By synchronously rotating any two of the first, second, third, and fourth drive shafts 310, 320, 330, and 340, while allowing the remaining two to rotate independently, the drive assembly can achieve linkage between any two of the four dampers, thereby meeting two-zone configuration requirements. This allows the air distribution device to flexibly achieve dual, three, or four-zone configurations based on customer needs, and since most parts are universal, costs are significantly reduced.

[0064] Through the nested arrangement of the first drive shaft 310 and the second drive shaft 320, as well as 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 miniaturization 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 has lower arrangement difficulty and occupies less space.

[0065] Optionally, the first air inlet channel can correspond to the left rear row of the vehicle, the second air inlet channel can correspond to the main driver's side of the vehicle, the third air inlet channel can correspond to the co-driver's side of the vehicle, and the fourth air inlet channel can correspond to the right rear row of the vehicle.

[0066] It will be understood that when the first damper 210 slides toward the first cold air duct 111, the opening of the first cold air duct 111 becomes smaller, while the opening of the first hot air duct 112 becomes larger. Similarly, when the second damper 220 slides toward the second cold air duct 121, the opening of the second cold air duct 121 becomes smaller, while the opening of the second hot air duct 122 becomes larger. When the third damper 230 slides toward the third cold air duct 131, the opening of the third cold air duct 131 becomes smaller, while the opening of the third hot air duct 132 becomes larger. When the fourth damper 240 slides toward the fourth cold air duct 141, the opening of the fourth cold air duct 141 becomes smaller, while the opening of the fourth hot air duct 142 becomes larger.

[0067] 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 indicated by the Y axis.

[0068] 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 .

[0069] 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 slidingly connected to the two first sliding grooves respectively. Such an arrangement can improve the smoothness and reliability of the sliding of the first air door 210.

[0070] 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 slidingly connected to the two second sliding grooves respectively. Such an arrangement can improve the smoothness and reliability of the sliding of the second air door 220.

[0071] Optionally, third sliding grooves are provided on both sides of the third air inlet channel along the first direction, and both sides of the third air door 230 are slidingly connected to the two third sliding grooves respectively. Such an arrangement can improve the smoothness and reliability of the sliding of the third air door 230.

[0072] 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 slidingly connected to the two fourth sliding grooves respectively. Such an arrangement can improve the smoothness and reliability of the sliding of the fourth air door 240.

[0073] Furthermore, in this embodiment, the housing 100 is provided with an air inlet channel. Three partitions are provided in the air inlet channel, spaced apart and arranged parallel to each other along a first direction. 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.
