DETAILED DESCRIPTION

[0042] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0044] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0045] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the invented product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0046] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0047] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0048] In the prior art, to adjust various air outlet modes, multiple independent dampers are typically installed within the distribution box. Each damper is mounted at a corresponding air outlet 102 and rotates with the box housing 100 to open or close the corresponding air outlet 102. Because each damper is independently designed, adjusting the air outlet mode requires the coordination of multiple dampers, making operation cumbersome. Furthermore, each air outlet 102 is equipped with a damper, resulting in a large number of dampers and a complex structure, which increases the risk of failure.

[0049] In view of this, the designer provides an air conditioning distribution box that simplifies the damper structure, reduces the number of dampers, and reduces the failure rate. At the same time, the air outlet mode switching operation is convenient.

[0050] Please combine Figure 1-Figure 4 In this embodiment, the air conditioning distribution box includes a box housing 100 and a damper assembly 200. The box housing 100 is provided with an air inlet 101 and multiple air outlets 102. The damper assembly 200 is installed in the box housing 100. The damper assembly 200 has multiple working states that can be switched between each other. The damper assembly 200 is used to connect the air inlet 101 with at least one air outlet 102 by switching between different working states to adjust the air outlet direction of the box housing 100.

[0051] As described above, the air conditioning distribution box provided in this embodiment works as follows:

[0052] When the air outlet mode needs to be adjusted, the damper assembly 200 can be operated. The switching of different working states of the damper assembly 200 can correspond to at least one air outlet mode, which is easy to operate. Specifically, by installing the damper assembly 200 inside the box shell 100, the working state of the damper assembly 200 can be adjusted as needed, so that the air inlet 101 on the box shell 100 can be connected to at least one corresponding air outlet 102 to achieve the switching of different air outlet modes. Since the damper assembly 200 can achieve the switching of multiple air outlet modes, compared with the existing technology that requires multiple independent dampers to cooperate to achieve mode adjustment, the structure is simplified, the processing and manufacturing costs are saved, and the failure rate is reduced; at the same time, the operation steps are simplified and the efficiency of switching the air outlet mode is improved.

[0053] The following embodiments illustrate the detailed structure of the air conditioning distribution box provided in this application by way of examples.

[0054] In this embodiment, optionally, the damper assembly 200 includes a damper outer cylinder 210 and a damper inner cylinder 220, the damper outer cylinder 210 is sleeved on the outside of the damper inner cylinder 220, and the damper outer cylinder 210 and the damper inner cylinder 220 are both installed inside the box shell 100, and the damper outer cylinder 210 and the damper inner cylinder 220 are rotatably matched to adjust multiple working states of the damper assembly 200.

[0055] With this design, the damper outer cylinder 210 and the damper inner cylinder 220 can be rotatably engaged to switch the operating state of the damper assembly 200, thereby adjusting the airflow direction. The damper assembly 200 has a simple structure, is easy to manufacture, and is compact, taking up little space and facilitating assembly. Furthermore, the multiple operating states can be switched through rotation, making operation convenient and flexible.

[0056] Optionally, the damper outer cylinder 210 is configured as a cylindrical structure, with an air inlet 211 and multiple air outlets 212 provided on the outer peripheral wall of the damper outer cylinder 210. The air inlet 211 is simultaneously connected to the multiple air outlets 212, and the multiple air outlets 212 are respectively connected to the multiple air outlets 102 in a one-to-one correspondence. Correspondingly, the damper inner cylinder 220 is configured as a cylindrical structure, with an air duct 221 provided on the outer peripheral wall of the damper inner cylinder 220. The air duct 221 is provided with a first port 222 and a second port 223 located on the outer peripheral wall.

The damper inner cylinder 220 is more stable and reliable when rotating, with high adjustment accuracy, which is conducive to switching the air outlet mode and air output volume.

[0059] Optionally, a seal is provided between the damper outer cylinder 210 and the damper inner cylinder 220. The sealing performance between the damper outer cylinder 210 and the damper inner cylinder 220 is high, air leakage is not easy, and the air volume adjustment is more stable.

[0061] In this embodiment, the damper outer cylinder 210 and the damper inner cylinder 220 may be optionally sealed at both axial ends. This provides for high sealing performance at the ends of the damper outer cylinder 210 and the damper inner cylinder 220, preventing air leakage and facilitating air volume control. It should be understood that in other embodiments, only the axial ends of the damper outer cylinder 210 or the axial ends of the damper inner cylinder 220 may be sealed, which can also improve sealing performance.

[0062] In this embodiment, optionally, there are three air outlets 102, which include a defrost outlet 1021, a face-blowing outlet 1022, and a foot-blowing outlet 1023 arranged in a ring.

[0063] Please combine Figure 5-Figure 9 Furthermore, the defrost port 1021, the face blowing port 1022, and the foot blowing port 1023 are sequentially arranged in the clockwise direction. The defrost, face blowing, and foot blowing modes can be adjusted individually according to needs. The defrost foot blowing mode and the defrost face blowing mode can also be adjusted. This allows for diverse modes and a wide range of applications.

[0064] The air conditioning distribution box provided in this embodiment can adjust various air outlet modes through the cooperation of the damper inner cylinder 220 and the damper outer cylinder 210. It has a compact structure, few parts, low processing and manufacturing costs, low failure rate and high stability.

[0065] This embodiment also provides a vehicle air-conditioning system, which includes an air-conditioning distribution box, an indoor unit 300 and an evaporator 400.
