Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an airflow adjustment device for plastic parts of automotive air conditioning systems. Background Technology
[0002] The airflow direction adjustment device in automotive air conditioning plastic parts is an important component of the automotive air conditioning system, mainly used to control the direction of air blown out of the air conditioning vents.
[0003] In existing technology, rotating blades can close the air outlet of the air conditioning plastic parts. When the vehicle is driving on a dusty road or passing through an area with an odor, closing the air direction adjustment device can effectively prevent external dust, smoke, odors and other pollutants from entering the vehicle.
[0004] However, in real-world applications, tiny gaps may still exist between the closed blades. Even when closed, air may leak into the vehicle's interior through these gaps, inevitably allowing external dust and odors to enter through unsealed vents, thus reducing the air quality inside the vehicle and hindering efforts to minimize the impact on the vehicle's interior.
[0005] Therefore, this application provides an airflow adjustment device for automotive air conditioning plastic parts to meet the requirements. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose an airflow direction adjustment device for plastic parts in automotive air conditioning systems.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an airflow direction adjustment device for automotive air conditioning plastic parts, comprising:
[0008] Plastic casing;
[0009] A sealing assembly is placed inside a plastic housing. The sealing assembly includes a frame fixed inside the plastic housing and blades rotatably connected to the frame. A sealing plate is fixedly connected to the frame on the side near the blades, and rubber pads are provided on both sides of the blades near the sealing plate.
[0010] A fastening assembly is placed inside the sealing assembly and is used to further reinforce the sealing effect between the sealing plate and the blade. The fastening assembly includes a magnet disposed on the blade near the sealing plate. A metal plate is fixedly connected inside the sealing plate near the magnet. Two magnets are disposed on the blade, and the two magnets are arranged in a mirror image on the blade.
[0011] Furthermore, a snap-fit block is fixedly connected to the side of the blade near the rubber pad, and the rubber pad is snapped to the blade through the snap-fit block.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the new rubber pad is snapped onto the snap-fit block one, which makes it easier to replace the rubber pad.
[0013] Furthermore, two snap-fit blocks are fixedly connected to both sides of the blade near the rubber pad, and the snap-fit blocks are snapped into the rubber pad.
[0014] The beneficial effect of adopting the above-mentioned further solution is that it limits the movement path of the rubber pad, so that the rubber pad and the snap-fit block can be quickly aligned, which helps to improve the installation efficiency of the rubber pad.
[0015] Furthermore, the top of the first snap-fit block has a chamfered structure.
[0016] The beneficial effect of adopting the above-mentioned further solution is that it increases the friction between the rubber pad and the snap-fit block, which helps to improve the stability of the rubber pad.
[0017] Furthermore, a groove is provided on the side of the blade near the magnet, and the magnet is slidably connected to the groove.
[0018] The beneficial effect of adopting the above-mentioned further solution is that it increases the friction between the rubber pad and the snap-fit block, which helps to improve the stability of the rubber pad.
[0019] Furthermore, spring pieces are provided on both sides of the inner side of the slide groove near the magnet. A fixing block is fixedly connected to the side of the spring piece near the slide groove and the magnet. The spring piece is engaged with the slide groove and the spring piece through the fixing block.
[0020] The beneficial effects of adopting the above-mentioned further solutions are: increasing the stability of the magnet during use, preventing the magnet from falling off, and further increasing the stability of the connection between the magnet and the spring.
[0021] Furthermore, a rotating shaft is fixedly connected to both sides of the blade near the frame, and a transmission plate is rotatably connected to the rotating shaft.
[0022] The beneficial effect of adopting the above-mentioned further solution is that the moving shaft drives the other shafts to move together through the transmission plate, thereby making the remaining blades open at the same time, which facilitates the simultaneous opening and closing of the blades.
[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0024] 1. By setting up a sealing assembly, four sealing plates are installed inside the frame, and a blade is installed between every two sealing plates. The distance between the sealing plates is less than the height of the blade. When the blade rotates and closes with the sealing plate, the rubber pads installed on both sides of the blade will fit tightly with the sealing plate, sealing the gap between the sealing plate and the blade. In this way, the problem of possible small gaps still existing after the blade is closed is solved, which helps to isolate external dust, odors and impurities outside the vehicle body, thereby helping to maintain the air quality inside the vehicle body and reduce the impact of external factors on the vehicle body interior.
[0025] 2. By setting up fastening components, the metal plate is installed inside the sealing plate. When the blade moves the rubber pad to fit against the sealing plate, the magnet on the blade interacts with the metal plate through its own magnetic force, thereby driving the blade to move further towards the sealing plate. Since the magnets are installed in a mirror image on both sides of the blade, both sides of the blade can be attracted to the sealing plate. The magnets on both sides of the blade will push the rubber pad to deform in the direction of the sealing plate, making the fit between the rubber pad and the sealing plate tighter. This helps to further reduce the gap between the sealing plate and the rubber pad, effectively improving the sealing effect. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an airflow direction adjustment device for plastic parts of an automotive air conditioner, comprising: a plastic housing 1;
[0036] like Figure 1 - Figure 4 As shown: sealing assembly 2, the sealing assembly 2 is placed inside the plastic shell 1, the sealing assembly 2 includes a frame 21 fixed inside the plastic shell 1 and a blade 23 rotatably connected to the frame 21, a sealing plate 22 is fixedly connected to the side of the frame 21 near the blade 23, and rubber pads 26 are provided on both sides of the blade 23 near the sealing plate 22.
[0037] like Figure 1 - Figure 4As shown: Fastening assembly 3, which is placed inside the sealing assembly 2 and used to further strengthen the sealing effect between the sealing plate 22 and the blade 23. The fastening assembly 3 includes a magnet 32 disposed on the blade 23 near the sealing plate 22. A metal plate 31 is fixedly connected to the side of the sealing plate 22 near the magnet 32. Two magnets 32 are disposed on the blade 23, and the two magnets 32 are arranged in a mirror image on the blade 23. By installing four sealing plates 22 inside the frame 21, with a blade 23 installed between every two sealing plates 22, and the distance between the sealing plates 22 is less than the height of the blade 23, when the blade 23 rotates and closes with the sealing plate 22, the rubber pads 26 installed on both sides of the blade 23 fit tightly with the sealing plate 22 to seal the gap between the sealing plate 22 and the blade 23, thereby solving the problem. Even after the blades 23 are closed, there may still be tiny gaps between them. This helps to isolate external dust, odors, and impurities from the vehicle body, maintaining air quality inside the vehicle and reducing the impact on the interior. Furthermore, by installing the metal plate 31 inside the sealing plate 22, when the blades 23 bring the rubber pad 26 into contact with the sealing plate 22, the magnets 32 on the blades 23, through their own magnetic force, work with the metal plate 31 to move the blades 23 further toward the sealing plate 22. Since the magnets 32 are mirror-mounted on both sides of the blades 23, both sides of the blades 23 are attracted to the sealing plate 22. This causes the magnets 32 on both sides to push the rubber pad 26 toward the sealing plate 22, making the rubber pad 26 fit more tightly with the sealing plate 22. This further reduces the gaps between the sealing plate 22 and the rubber pad 26, improving the sealing effect.
[0038] Furthermore, such as Figure 3 As shown: A snap-fit block 27 is fixedly connected to the side of the blade 23 near the rubber pad 26. The rubber pad 26 is snapped to the blade 23 through the snap-fit block 27. By opening a snap-fit groove on the rubber pad 26 that matches the snap-fit block 27, the rubber pad 26 can be easily installed and removed from the snap-fit block 27. When the rubber pad 26 wears out after long-term use, the rubber pad 26 is pulled to separate the snap-fit groove on the rubber pad 26 from the snap-fit block 27. Then, a new rubber pad 26 is snapped onto the snap-fit block 27, thereby completing the replacement of the rubber pad 26.
[0039] Furthermore, such as Figure 3 As shown: Both sides of the blade 23 near the rubber pad 26 are fixedly connected to the second snap-fit block 28. The second snap-fit block 28 snaps into the rubber pad 26. By opening a groove on the rubber pad 26 that matches the second snap-fit block 28, when the rubber pad 26 needs to be installed, the rubber pad 26 first aligns with the second snap-fit block 28 through the groove, which limits the movement path of the rubber pad 26, so that the rubber pad 26 can be quickly aligned with the first snap-fit block 27, which helps to improve the installation efficiency of the rubber pad 26.
[0040] Furthermore, such as Figure 3 As shown: The top of the snap-fit block 27 has a chamfered structure. By opening the same chamfered structure as on the snap-fit block 27 inside the snap-fit groove opened on the rubber pad 26, when the rubber pad 26 is snapped onto the snap-fit block 27, the chamfer on the snap-fit block 27 can increase the contact area between the rubber pad 26 and the snap-fit block 27, increase the friction between the rubber pad 26 and the snap-fit block 27, and help improve the stability of the rubber pad 26.
[0041] Furthermore, such as Figure 3 As shown: A groove 33 is provided on the side of the blade 23 near the magnet 32. The magnet 32 is slidably connected to the groove 33. By opening a chamfer structure inside the snap-fit groove on the rubber pad 26, the same as that on the snap-fit block 27, when the rubber pad 26 is snapped onto the snap-fit block 27, the chamfer on the snap-fit block 27 can increase the contact area between the rubber pad 26 and the snap-fit block 27, increase the friction between the rubber pad 26 and the snap-fit block 27, and help improve the stability of the rubber pad 26.
[0042] Furthermore, such as Figure 3 As shown: On both sides of the inner side of the slide groove 33 near the magnet 32, there are spring pieces 34. A fixing block 35 is fixedly connected to the side of the spring piece 34 near the slide groove 33 and the magnet 32. The spring piece 34 is engaged with the slide groove 33 and the spring piece 34 through the fixing block 35. By installing the spring piece 34 inside the slide groove 33, it is convenient for the spring piece 34 to clamp the magnet 32 installed inside the slide groove 33, which increases the stability of the magnet 32 during use and prevents the magnet 32 from falling off. Furthermore, by using the hemispherical fixing block 35 to engage the slide groove 33 and the magnet 32 together, the stability of the connection between the magnet 32 and the spring piece 34 is further increased.
[0043] Furthermore, such as Figure 4 As shown: Rotating shafts 25 are fixedly connected to both sides of the blade 23 near the frame 21. A transmission plate 24 is rotatably connected to the rotating shaft 25. By pushing the blade 23 to rotate, when the moving blade 23 rotates, the rotating shaft 25 on the blade 23 moves together. Since the transmission plate 24 is connected to the rotating shaft 25, the moving rotating shaft 25 drives the other rotating shafts 25 to move together through the transmission plate 24, thereby causing the remaining blades 23 to open at the same time, which facilitates the simultaneous opening and closing of the blades 23.
[0044] Working principle: such as Figure 1 - Figure 4As shown, rotating one blade 23 causes it to rotate along its own axis 25 inside the frame 21. The axis 25 on the blade 23 drives the other transmission plates 24 to move together via the transmission plate 24, causing the remaining blades 23 to rotate along with the first rotating blade 23, closing the air outlet of the plastic shell 1. When the blade 23 rotates and closes with the sealing plate 22, the rubber pads 26 installed on both sides of the blade 23 fit tightly against the sealing plate 22, sealing the gap between the sealing plate 22 and the blade 23. At this time, the magnet 32 on the blade 23, through its own magnetic force, cooperates with the metal plate 31 to drive the blade 23 to continue moving towards the sealing plate 22, thereby causing the magnets 32 on both sides to push the rubber pads 26 to deform towards the sealing plate 22, making the rubber pads 26 fit more tightly against the sealing plate 22, which is beneficial for absorbing external dust, odors and other impurities. The air quality is isolated outside the vehicle body, which helps maintain the air quality inside the vehicle body and reduces the impact on the vehicle body. When the rubber pad 26 and magnet 32 have been used for a long time, they need to be replaced. Pull the rubber pad 26 upward to separate the snap-fit groove on the rubber pad 26 from the snap-fit block 27 and replace the rubber pad 26. When installing the new rubber pad 26, the groove on the rubber pad 26 is first aligned with the snap-fit block 28 to limit the movement path of the rubber pad 26, which helps to improve the installation efficiency of the rubber pad 26. Then push the magnet 32 upward. When the magnet 32 moves, it squeezes the spring piece 34, causing the spring piece 34 to contract and the fixing block 35 to separate from the magnet 32. Then the magnet 32 is taken out and placed inside the slide groove 33. The fixing block 35 on the spring piece 34 snaps into the magnet 32 and fixes the magnet 32 inside the slide groove 33.
[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
