[0039] Please refer to Figures 1-6This embodiment provides an automotive air conditioning unit 100, which includes a main body 110 and a damper assembly 130;

[0040] The main body 110 is provided with an air guide cavity 111, a first air inlet 112, a second air inlet 113, and an exhaust outlet 114; the first air inlet 112, the second air inlet 113, and the exhaust outlet 114 are all connected to the air guide cavity 111, and the opening of the first air inlet 112 faces the first direction (as shown by arrow A in the figure), and the opening of the second air inlet 113 faces the second direction (as shown by arrow B in the figure), and the first direction and the second direction are at an angle;

[0041] The damper assembly 130 is connected to the main body 110 and is used to enable one or both of the first air inlet 112 and the second air inlet 113 to communicate with the air guide cavity 111.

[0042] The working principle of the car air conditioning unit 100 is as follows:

[0043] The automotive air conditioning unit 100 includes a main body 110 and an air damper assembly 130; the main body 110 is provided with an air guide cavity 111, a first air inlet 112, a second air inlet 113, and an exhaust outlet 114; wherein, when configuring the first air inlet 112 and the second air inlet 113, one of the first air inlet 112 and the second air inlet 113 can be configured as an external circulation air inlet. Figure 4 The middle arrow E indicates the direction of external air intake, and the other configuration is an internal air intake. Figure 4 The middle arrow F indicates the direction of external air intake, while a filter is installed at the exhaust vent 114;

[0044] The first air inlet 112, the second air inlet 113, and the exhaust outlet 114 are all connected to the air guide cavity 111. The opening of the first air inlet 112 faces the first direction, and the opening of the second air inlet 113 faces the second direction. The first direction and the second direction are at an angle. The damper assembly 130 is connected to the main body 110 and is used to connect one or both of the first air inlet 112 and the second air inlet 113 to the air guide cavity 111. It should be noted that when the damper assembly 130 is configured, its function is to adjust the connection between the first air inlet 112 and the second air inlet 113 and the air guide cavity 111. The connection here includes adjusting its opening and blocking states, as well as adjusting the size of its connecting surface. That is, it can adjust the flow rate of the first air inlet 112 and the second air inlet 113 and the air guide cavity 111.

[0045] Therefore, taking the first air inlet 112 as the external circulation air inlet and the second air inlet 113 as the internal circulation air inlet as an example, since the opening direction of the first air inlet 112 is the first direction and the opening direction of the second air inlet 113 is the second direction, and the first direction and the second direction form an angle, therefore, taking the car air conditioning unit 100 and the passenger compartment (such as...) as an example... Figure 4 When the first air inlet 112 is arranged sequentially along the first direction (as indicated by the mark C), the opening direction of the first air inlet 112 is away from the passenger compartment. Since the second direction is at an angle to the first direction, the opening direction of its internal circulation air inlet can be avoided from facing the passenger compartment directly, thereby reducing its noise radiation towards the passenger compartment.

[0046] Therefore, the automotive air conditioning unit 100 is used in the automotive air conditioning system, which can avoid directing the direction of the internal air circulation into the passenger compartment, thereby effectively reducing noise radiation towards the passenger compartment, and thus improving the passenger's riding experience and comfort.

[0047] It should be noted that in this embodiment, the first direction is perpendicular to the second direction, and the first air inlet 112 is an external circulation air inlet, while the second air inlet 113 is an internal circulation air inlet. In other embodiments of this utility model, the angle between the first direction and the second direction can be 60°-120°, that is, the angle between the first direction and the second direction is 60°, 90° or 120°. In this way, when internal circulation is achieved by air intake through the first air inlet 112, noise radiated towards the passenger compartment due to the position of the internal circulation air inlet facing the passenger compartment can be avoided.

[0048] Further, please refer to Figures 1-6 In this embodiment, when configuring the first air inlet 112 and the second air inlet 113, since this embodiment adopts a method in which the first direction is perpendicular to the second direction, the first air inlet 112 and the second air inlet 113 can be configured on two vertical sides of the main body 110.

[0049] Based on this, to facilitate the subsequent installation of the damper assembly 130, in this embodiment, the automotive air conditioning unit 100 also includes a first internal circulation air guide chamber 115 connected to the main body 110. The first air inlet 112 is opened in the first internal circulation air guide chamber 115, with the first direction perpendicular to the second direction. That is, in this embodiment, when configuring the first air inlet 112, it can be configured on one side of the main body 110. Since the opening direction of the second air inlet 113 is perpendicular to the opening direction of the first air inlet 112, in order to facilitate the configuration of the damper assembly 130 inside the main body 110, the first internal circulation air guide chamber 115 connected to the main body 110 is configured on the basis of the main body 110, so that when configuring the second air inlet 113, its opening direction can be adapted.

[0050] Meanwhile, the damper assembly 130 includes a first movable damper 131 and a second movable damper 132. The first movable damper 131 is rotatably disposed in the air guide cavity 111, and the second movable damper 132 is rotatably disposed at the connection between the first internal circulation air guide chamber 115 and the main body 110. The first movable damper 131 and the second movable damper 132 are spaced apart along a first direction, and the rotation axis of the first movable damper 131 and the rotation axis of the second movable damper 132 are both parallel to the second direction. The first movable damper 131 is used to connect or block the first air inlet 112 with the air guide cavity 111; the second movable damper 132 is used to connect or block the first internal circulation air guide chamber 115 with the air guide cavity 111.

[0051] Therefore, through the aforementioned structural arrangement of the first internal circulation air inlet chamber, the first movable damper 131, and the second movable damper 132, the structural arrangement of the second air inlet 113 can be simplified. Furthermore, the first and second movable dampers 131 and 132 can not only adjust the connection state between the first and second air inlets 112 and 113 and the air guide cavity 111, but also adjust the flow rate at the connection point. It should be noted that the first and second movable dampers 131 and 132 are configured with their rotation axes evenly parallel in the second direction. This simplifies the structural arrangement. A drive structure 150 is provided to drive the rotation of the first and second movable dampers 131 and 132. The drive structure 150 can be a conventional motor drive, and therefore will not be described in detail here.

[0052] During the operation of the car air conditioning unit 100, in order to prevent the first air inlet 112 from being in the air intake and realizing external circulation, some of the airflow introduced into the air guide cavity 111 through the first air inlet 112 will flow to the second air inlet 113, thereby reducing the air intake volume of the external circulation, and at the same time generating corresponding noise and reducing its circulation efficiency.

[0053] Based on this, please refer to Figures 1-6 The damper assembly 130 also includes a third movable damper 133, which is rotatably disposed in the air guide cavity 111. The rotation axis of the third movable damper 133 is parallel to the second direction, and the third movable damper 133 is located between the first movable damper 131 and the second movable damper 132. The third movable damper 133 is used to guide the airflow introduced by the first air inlet 112 toward the air outlet 114.

[0054] Since the third movable damper 133 is located between the first movable damper 131 and the second movable damper 132, and the rotation axes of the three dampers are parallel, the third movable damper 133 can adjust the airflow direction in the air guide cavity 111 through its rotation control. This allows the airflow introduced by the first air inlet 112 to flow towards the exhaust port 114. Thus, when the first air inlet 112 is in the air intake and external circulation is achieved, the airflow introduced into the air guide cavity 111 through the first air inlet 112 can flow towards the exhaust port 114 under the guidance of the third movable damper 133. This avoids or reduces the airflow in the air guide cavity 111 from flowing into the second air inlet 113, thereby reducing the flow of air and ensuring the intake volume of the external circulation, reducing noise, and ensuring its circulation efficiency.

[0055] It should be noted that when the first movable damper 131 adjusts the connection between the first air inlet 112 and the air guide cavity 111, and the second movable damper 132 adjusts the connection between the second air inlet 113 and the air guide cavity 111, since the first movable damper 131 and the second movable damper 132 operate independently, during use, not only are the connection states of the two dampers adjusted independently and their flow rates adjusted, but there is also a state where the two dampers are simultaneously connected; that is, there is a state where the first air inlet 112 and the second air inlet 113 are simultaneously connected to the air guide cavity 111. At this time, through the structural setting of the third movable damper 133, the airflow introduced by the first air inlet 112 can be prevented from being discharged through the connected second air inlet 113, thereby reducing crossflow. In addition, the car air conditioning unit 100 is provided with a drive structure 150 for driving the third movable air door 133 to rotate. The drive structure 150 can adopt drive components such as motors in the prior art, so it will not be described in detail here.

[0056] Further, please refer to Figures 1-6Based on the structure with the third movable air damper 133 described above, in this embodiment, the automotive air conditioning unit 100 also includes a second internal circulation air guide chamber 116 connected to the main body 110. The second internal circulation air guide chamber 116 has a third air inlet 117 on one side along the second direction. The rotation axis of the third movable air damper 133 is located at the connection between the second internal circulation air guide chamber 116 and the main body 110, and the third movable air damper 133 is also used to connect or block the second internal circulation air guide chamber 116 from the air guide cavity 111.

[0057] That is, by setting it up in this way, in order to increase the air intake during the internal circulation process, a second internal circulation air guide chamber 116 can be set up, and a third air inlet 117 can be opened on the second internal circulation air guide chamber 116. The direction of the third air inlet 117 is the same as the direction of the second air inlet 113. Thus, when internal circulation is realized, air can be introduced simultaneously through the second air inlet 113 and the third air inlet 117, thereby increasing the air intake in the internal circulation state and improving the internal circulation efficiency.

[0058] Furthermore, with the aforementioned third movable damper 133 configured, in addition to guiding the airflow in the air guide cavity 111 and reducing the airflow that flows into the second air inlet 113, the third movable damper 133's rotation axis is located at the connection between the second internal circulation air guide chamber 116 and the main body 110. The third movable damper 133 is also used to connect or block the second internal circulation air guide chamber 116 and the air guide cavity 111. Therefore, the third movable damper 133 can both guide the air in the air guide cavity 111 and adjust the internal circulation air intake, thereby improving its operational flexibility and reducing its noise during operation.

[0059] When configuring the first internal circulation air guide chamber 115 and the second internal circulation air guide chamber 116, the first internal circulation air guide chamber 115 and the second internal circulation air guide chamber 116 are arranged side by side and connected, and the second air inlet 113 and the third air inlet 117 are arranged on the same side. In order to avoid crossflow between the first internal circulation air guide chamber 115 and the second internal circulation air guide chamber 116 during the air intake process, an air guide plate 118 is provided between the first internal circulation air guide chamber 115 and the second internal circulation air guide chamber 116. The air guide plate 118 extends from the connection between the first internal circulation air guide chamber 115 and the air guide cavity 111 in a direction away from the air guide cavity 111, and blocks part of the connection between the first internal circulation air guide chamber 115 and the second internal circulation air guide chamber 116.

[0060] Based on the above structure, to improve its operational flexibility and increase its air intake during the internal circulation process, in addition to configuring the aforementioned first internal circulation air guide chamber 115 and second internal circulation air guide chamber 116, please refer to... Figures 1-8 The car air conditioning unit 100 also includes a third internal circulation air guide chamber 119 connected to the main body 110. The third internal circulation air guide chamber 119 has a fourth air inlet 121. The first movable air damper 131 is used to connect one or both of the third internal circulation air guide chamber 119 and the first air inlet 112 to the air guide inner cavity 111.

[0061] That is, through the above-described structural arrangement, the automotive air conditioning unit 100 can intake air through three air chambers during the internal circulation process, thereby improving its air intake volume and internal circulation efficiency. Furthermore, the third internal circulation air chamber 119 can be adjusted for conduction by changing the rotation position of the first movable damper 131, allowing the first movable damper to adjust the conduction state and flow rate of the third internal circulation air chamber 119, as well as the conduction state and flow rate of the first air inlet 112. Moreover, when configuring the third internal circulation air chamber 119, the air inlets can be configured such that a fourth air inlet 121 and a fifth air inlet 122 are respectively opened on both sides along the second direction. The third internal circulation air chamber 119 can also have a sixth air inlet 123, with the opening direction of the sixth air inlet 123 being the same as that of the first air inlet 112.

[0062] Therefore, by setting the fourth air inlet 121, the fifth air inlet 122 and the sixth air inlet 123 as described above, the opening flow rate that can be introduced into the third internal circulation air guide chamber 119 can be increased, thereby increasing the air intake volume of the internal circulation.

[0063] In summary, based on the above information, please refer to... Figures 1-8 During use, the automotive air conditioning unit 100 can achieve external air circulation or internal air circulation by rotating the first movable air damper 131, the second movable air damper 132 and the third movable air damper 133. Furthermore, since the three movable air dampers can be controlled independently, external air circulation and internal air circulation can coexist under specific working conditions by controlling the first movable air damper 131, the second movable air damper 132 and the third movable air damper 133.

[0064] In the external circulation mode, the second movable damper 132 blocks the first internal circulation air guide chamber 115 from the air guide cavity 111, and the third movable damper 133 blocks the second internal circulation air guide chamber 116 from the air guide cavity 111. The first movable damper 131 connects the first air inlet 112 to the air guide cavity 111, so that air can be introduced through the first air inlet 112 to achieve external circulation. It should be noted that in the external circulation mode, the third movable damper 133 can also connect the second internal circulation air guide chamber 116 to the air guide cavity 111. At this time, the third movable damper 133 is used to guide the airflow introduced by the first air inlet 112 toward the exhaust port 114, so as to avoid crossflow.

[0065] In the internal circulation mode, the first movable damper 131 blocks the first air inlet 112 from the air guide cavity 111, the second movable damper 132 connects the first internal circulation air guide chamber 115 to the air guide cavity 111, and the third movable damper 133 connects the second internal circulation air guide chamber 116 to the air guide cavity 111. Thus, air can be guided to the air guide cavity 111 through the first internal circulation air guide chamber 115, the second internal circulation air guide chamber 116, and the third internal circulation air guide chamber 119. That is, at this time, air enters through the second air inlet 113, the third air inlet 117, the fourth air inlet 121, the fifth air inlet 122, and the sixth air inlet 123, achieving internal circulation. It should be noted that in the internal circulation mode, the air intake direction is towards the passenger compartment, thus reducing the impact of air intake noise on the passenger compartment.

[0066] Based on the above, please refer to Figures 1-8 This embodiment also provides an automotive air conditioning system, which includes the aforementioned automotive air conditioning unit 100. By employing the aforementioned automotive air conditioning unit 100, this automotive air conditioning system possesses all the advantages of the aforementioned automotive air conditioning unit 100, which will not be elaborated further here.

[0067] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
