Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, and in particular to an automotive air conditioning air intake box and an automotive air conditioner. Background Technology

[0002] With the rapid development of electric vehicles, competition in the automotive industry is intensifying, making the optimization and redesign of traditional models imperative. To further improve user thermal comfort while also meeting energy-saving requirements, OEMs are imposing increasingly stringent design requirements on air intake boxes, upgrading from the traditional internal and external circulation modes to a hybrid mode with an adjustable ratio of internal and external air intake, while ensuring that the hybrid mode is completely free of draft.

[0003] Existing air intake boxes cannot meet the requirements for preventing cross-flow in mixed-mode operation. When a vehicle is traveling at high speed, the greater pressure generated at the external air intake will force the airflow directly into the internal air circulation channel, a phenomenon known as "cross-flow." This cross-flow not only affects the air quality inside the vehicle and causes turbulent airflow, but also reduces the operating efficiency of the car's air conditioning system, increases energy consumption, and seriously affects passenger comfort.

[0004] Therefore, there is an urgent need to design an automotive air conditioning intake box and an automotive air conditioning system to solve the above technical problems. Utility Model Content

The external circulation damper and the housing form an external circulation duct, and the internal circulation damper and the housing form an internal circulation duct.

[0009] A windbreak baffle is disposed inside the housing and is connected to the inner wall of the housing; in the mixed mode, the internal circulation damper and the windbreak baffle form a sealing structure to isolate the external circulation duct and the internal circulation duct.

[0010] As an optional technical solution for automotive air conditioning intake boxes, the internal circulation damper has a fixed end and a movable end. The fixed end is rotatably connected to the housing, and the movable end is provided with a silicone sleeve.

The second plate is connected to the first plate, and the third plate abuts against the first plate. In the mixing mode, the internal circulation damper opens and abuts against the second plate to form a sealing structure.

[0013] As an optional technical solution for an automotive air conditioning intake box, a first connecting part is provided on the first plate, and a second connecting part is provided on the second plate, with the first connecting part and the second connecting part connected together.

[0014] As an optional technical solution for an automotive air conditioning intake box, the first connecting part has a first internal threaded hole, the second connecting part has a second internal threaded hole, and the automotive air conditioning intake box further includes a screw rod, which passes through the first internal threaded hole and the second internal threaded hole to connect the first plate body and the second plate body.

[0018] As an optional technical solution for automotive air conditioning intake boxes, the outer edges of the first plate and the third plate are arranged in an arc shape to match the filter element.

[0019] The second objective of this invention is to provide an automotive air conditioner that can reduce the phenomenon of drafts in mixed mode, ensure air quality inside the vehicle, and improve passenger comfort.

[0020] To achieve this objective, the present invention adopts the following technical solution:

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] This embodiment provides an air intake box for automotive air conditioning, which reduces the phenomenon of air leakage in mixed mode, ensures air quality inside the vehicle, and improves passenger comfort.

[0042] like Figures 1-6As shown, the automotive air conditioning intake box mainly includes a housing 10 and a baffle plate 20. The housing 10 is equipped with an external circulation damper 11 and an internal circulation damper 12, both of which are rotatably connected to the housing 10. The external circulation damper 11 and the housing 10 form an external circulation duct 40, and the internal circulation damper 12 and the housing 10 form an internal circulation duct 50. The baffle plate 20 is disposed inside the housing 10 and is connected to the inner wall of the housing 10. In mixed mode, the internal circulation damper 12 and the baffle plate 20 form a sealed structure to isolate the external circulation duct 40 and the internal circulation duct 50.

[0043] Based on the above design, the housing 10 provides a stable mounting base for the external circulation damper 11 and the internal circulation damper 12. At the same time, through the rotational connection, the external circulation damper 11 and the internal circulation damper 12 can flexibly adjust their opening angles in different modes, thereby enabling the external circulation duct 40 and the internal circulation duct 50 to be opened or closed, meeting the air intake requirements of the automotive air conditioner under different operating conditions.

[0044] When the car's air conditioning is in mixed mode, both the external circulation damper 11 and the internal circulation damper 12 are open. At this time, the internal circulation damper 12 rotates and forms a sealing structure with the wind deflector 20, thereby isolating the external circulation duct 40 and the internal circulation duct 50. This effectively prevents the airflow in the external circulation duct 40 from entering the internal circulation duct 50, avoiding problems such as decreased air quality, airflow turbulence, and reduced operating efficiency of the car's air conditioning caused by airflow leakage. This improves the comfort of passengers in the car and reduces energy consumption.

[0045] In some alternative embodiments, the internal circulation damper 12 has a fixed end and a movable end, the fixed end being rotatably connected to the housing 10, and the movable end being provided with a silicone sleeve; in the mixing mode, the movable end rotates and forms a sealing structure with the wind deflector 20.

[0046] By installing a silicone sleeve at the movable end of the internal circulation damper 12, in mixed mode, when the internal circulation damper 12 rotates to contact the wind deflector 20, the silicone sleeve provides good elasticity and flexibility, filling the tiny gaps between the internal circulation damper 12 and the wind deflector 20, thereby enhancing the sealing effect. This further ensures effective isolation between the external circulation duct 40 and the internal circulation duct 50, making the anti-slip airflow performance more reliable, thus better maintaining the air quality inside the vehicle, improving passenger comfort, and reducing energy loss of the car's air conditioning system, improving its operating efficiency.

[0047] For example, the rotation angles of the external circulation damper 11 and the internal circulation damper 12 when they are opened can be flexibly designed according to actual needs. For example, the maximum rotation angle of the external circulation damper 11 is set to 75°, and the maximum rotation angle of the internal circulation damper 12 is set to 65°. That is, when the internal circulation damper 12 rotates to 65°, it forms a sealing structure with the wind baffle 20.

[0048] In some alternative embodiments, both the external circulation damper 11 and the internal circulation damper 12 can be rotatably connected to the housing 10 through a conventional connection method with shaft hole fitting, or they can be rotatably connected through a hinge-type or bearing-type connection method.

[0049] like Figures 2-3 As shown, in this embodiment, the windbreak baffle 20 includes a first plate 21, a second plate 22, and a third plate 23, and the housing 10 includes an upper housing 13 and a lower housing 14, which are fastened together. The first plate 21 is disposed on the inner wall of the upper housing 13, and the second plate 22 and the third plate 23 are both disposed on the inner wall of the lower housing 14. The second plate 22 is connected to the first plate 21, and the third plate 23 abuts against the first plate 21. In the mixed mode, the internal circulation damper 12 opens and abuts against the second plate 22 to form a sealing structure.

[0050] The windshield baffle 20 is divided into a first plate 21, a second plate 22, and a third plate 23, which are respectively installed on the inner walls of the upper housing 13 and the lower housing 14. This allows for more flexible installation and layout according to the internal space structure of the housing 10, improving space utilization. Simultaneously, the connection between the second plate 22 and the first plate 21, and the abutment between the third plate 23 and the first plate 21, form a stable support structure, enhancing the overall strength of the windshield baffle 20. In mixed mode, the internal circulation damper 12 abuts against the second plate 22 to form a sealing structure, preventing external circulation air from entering the internal circulation duct 50, thus improving the reliability of the automotive air conditioning intake box.

[0051] For example, the upper housing 13 and the lower housing 14 can be connected by snap-fit ​​or by bolts.

[0052] like Figures 2-3 As shown, in this embodiment, a first connecting part 211 is provided on the first plate 21, and a second connecting part 221 is provided on the second plate 22. The first connecting part 211 and the second connecting part 221 are connected.

[0053] Specifically, the first connecting part 211 has a first internal threaded hole, the second connecting part 221 has a second internal threaded hole, and the automotive air conditioning intake box also includes a screw rod, which passes through the first internal threaded hole and the second internal threaded hole to connect the first plate 21 and the second plate 22.

[0054] The first plate 21 and the second plate 22 are connected by a screw connection, providing a strong and reliable connection. The screw connection has high connection strength and can withstand certain tensile and compressive forces, ensuring that the first plate 21 and the second plate 22 maintain a stable connection under various operating conditions during vehicle operation. This helps maintain the overall structural stability of the windshield baffle 20, thereby ensuring the sealing performance between the internal circulation damper 12 and the windshield baffle 20, and further improving the anti-slip airflow capability of the vehicle's air conditioning intake box.

[0055] In some optional embodiments, the first connecting part 211 is a socket, and the second connecting part 221 is a pin, with the pin inserted into the socket. The structure of providing a socket and pin at the connection between the first plate 21 and the second plate 22 allows for quick and accurate positioning and connection during assembly. This not only improves assembly efficiency but also ensures connection accuracy, avoiding problems such as poor sealing due to positional deviations, and further enhances the assembly quality and performance stability of the automotive air conditioning intake box.

[0056] like Figures 2-6 As shown, in this embodiment, the car air conditioning intake box has a filter element 30, and the lower housing 14 has a mounting hole 141 located between the second plate 22 and the third plate 23; the filter element 30 is disposed between the first plate 21 and the third plate 23, and one end of the filter element 30 faces the mounting hole 141.

[0057] By opening a mounting hole 141 in the lower housing 14 and placing the filter element 30 between the first plate 21 and the third plate 23, the installation position of the filter element 30 is more reasonable and easier to install and replace. The filter element 30 can filter the air entering the car's air conditioning system, removing dust, impurities, and other pollutants, thereby improving the air quality inside the vehicle and ensuring the health and comfort of passengers. At the same time, the design of one end of the filter element 30 facing the mounting hole 141 facilitates the installation and removal of the filter element 30, improving the efficiency of assembly and disassembly.

[0058] Furthermore, the automotive air conditioning intake box in this embodiment also includes a cover plate 15, which is detachably installed in the mounting hole 141. The detachable cover plate 15 allows for easy opening during the installation or replacement of the filter element 30, making the installation and replacement process more convenient and efficient. Furthermore, after the filter element 30 is installed, the cover plate 15 can seal the mounting hole 141, preventing foreign objects from clogging it.

[0059] In some optional embodiments, the outer edges of the first plate 21 and the third plate 23 are arc-shaped to fit the filter element 30. Designing the outer edges of the first plate 21 and the third plate 23 to fit the filter element 30 allows the filter element 30 to fit better between them, increasing the contact area between the filter element 30 and the first plate 21 and the third plate 23, thereby improving the installation stability of the filter element 30. This prevents the filter element 30 from shifting or loosening during use due to airflow impact, ensuring that the filter element 30 always maintains a good filtration effect, further guaranteeing the stability and reliability of the air quality inside the vehicle.

[0060] In some optional embodiments, the gap between the outer edges of the first plate 21 and the third plate 23 and the filter element 30 is not less than 1 mm. On the one hand, during vehicle operation, the car air conditioner may be subjected to a certain degree of vibration and shaking. If the gap between the outer edges of the first plate 21 and the third plate 23 and the filter element 30 is too small (less than 1 mm), the filter element 30 may collide and rub against the first plate 21 and the third plate 23 during vibration, causing mechanical damage to the filter element 30 and affecting its filtration performance and service life. Setting a gap of not less than 1 mm provides a certain buffer space for the filter element 30, reducing collisions and friction caused by vibration and other reasons, thereby protecting the integrity of the filter element 30 and extending its service life. On the other hand, when installing or replacing the filter element 30, a gap of not less than 1 mm provides sufficient operating space, making it easier to insert or remove the filter element 30. This facilitates the regular replacement and cleaning of the filter element 30 by maintenance personnel, improving maintenance efficiency.

[0061] Optionally, in this embodiment, the external circulation damper 11 and the internal circulation damper 12 can each be set to one, or both can be set to two, or other quantities. For example... Figures 4-6 As shown, both the external circulation damper 11 and the internal circulation damper 12 are configured in pairs. Figure 4 As shown, when the car's air conditioning is in external circulation mode, both external circulation dampers 11 are open, and both internal circulation dampers 12 are closed, connecting the external circulation duct 40 and the internal circulation duct 50. Figure 5 As shown, when the car's air conditioning is in recirculation mode, both recirculation dampers 12 are open, and both external recirculation dampers 11 are closed, connecting the external recirculation duct 40 and the recirculation duct 50. Figure 6As shown, when the car's air conditioning is in mixed mode, both external circulation dampers 11 are open, the internal circulation damper 12 closer to the external circulation damper 11 is closed, and the internal circulation damper 12 farther from the external circulation damper 11 is open, forming a sealed structure with the wind deflector 20. At this time, the external circulation duct 40 and the internal circulation duct 50 are mutually sealed and isolated. Typically, customers adjust the internal and external circulation mixing ratio according to vehicle conditions in mixed mode to achieve energy savings and ensure customer comfort. Therefore, in mixed mode, the angle of the internal circulation damper 12 is fixed, while the angle of the external circulation damper 11 can be flexibly adjusted at multiple angles. Customers can then select different angles of the external circulation damper 11 according to their actual needs. Specifically, the car's central control screen offers multiple mixed modes for customers to choose from, such as Mixed Mode 1, Mixed Mode 2, Mixed Mode 3, etc. Different types of mixed modes correspond to different opening angles of the external circulation damper 11, allowing passengers to flexibly select various mixed modes on the central control screen to improve passenger comfort. Figures 4-6 The dashed arrow indicates the direction of airflow.

[0062] This embodiment also provides an automotive air conditioner, which includes a blower and the aforementioned automotive air conditioner air intake box, with the blower connected to the housing 10 of the automotive air conditioner air intake box. By combining the aforementioned automotive air conditioner air intake box, which has excellent anti-fouling performance and filtration effect, with the blower, the automotive air conditioner can effectively control the air intake of the external and internal circulation ducts 50 during operation, preventing various problems caused by fouling. After the blower is connected to the housing 10 of the automotive air conditioner air intake box, it can deliver the treated air to various air outlets inside the vehicle according to the set air volume and air pressure, thereby providing passengers with a comfortable and healthy in-vehicle environment.
