[0048] The air guide damper assembly 3 according to an embodiment of the present invention is described below with reference to the accompanying drawings, such as... Figure 1 As shown, it is applied to air conditioner 1000, and is usually used at the indoor air outlet 101 of air conditioner 1000 for adjusting the air outlet direction, etc. It is also possible that in some designs, the air guide damper assembly 3 is installed inside the air duct.

[0049] According to the air guide damper assembly 3 of the present utility model embodiment, referring to... Figures 2-3 The air guide damper assembly 3 includes a door panel 31 and a bearing 32. The bearing 32 is at least one and is provided on the door panel 31. The bearing 32 is provided with an assembly hole 321.

[0050] The air deflector assembly 3 also includes a pin shaft 33, which includes a plug portion 331, a shaft portion 333, and a connecting portion 335, with the connecting portion 335 connected between the plug portion 331 and the shaft portion 333.

[0051] The door panel 31 has a slot 3101 near the bearing 32. The insertion part 331 is inserted into the slot 3101, and the rotating shaft part 333 is partially inserted into the mounting hole 321 and partially located outside the mounting hole 321, so as to serve as the rotating shaft of the air guide damper assembly 3.

[0052] In other words, when forming the rotating shaft structure of the air deflector assembly 3, the rotating shaft and the bearing seat are not formed as a single unit, but rather the two parts are processed separately. The pin rotating shaft 33 is divided into an insertion part 331, a rotating shaft part 333, and a connecting part 335. The insertion part 331 is used to insert and connect to the door panel 31, thus fixing the pin rotating shaft 33. The rotating shaft part 333 is assembled into the mounting hole 321 of the bearing seat 32, allowing for quick positioning of the pin rotating shaft 33 and also serving as a rotating shaft.

[0053] Here, the insertion part 331 is inserted into the slot 3101 of the door panel 31. This means that the insertion and fixing part can be at least partially hidden inside the door panel 31, rather than protruding completely from the surface of the door panel 31. This reduces the space occupied by the pin pivot 33 in the airflow channel, which helps to reduce overall wind resistance. Moreover, with this arrangement, the connection between the insertion part 331 and the door panel 31 can utilize the structural strength of the door panel 31 itself to obtain greater stability. Compared with the solution where it protrudes from the surface of the door panel 31, the insertion part 331 in this application is less prone to breakage.

[0054] In summary, the proposed solution reduces airflow resistance and ensures the reliable connection of the pin shaft 33 to the door panel 31. Furthermore, the plug-in connection method allows for quick and easy positioning of the pin shaft 33 during assembly, facilitating accurate positioning of the shaft portion 333 and improving the operational stability of the air deflector assembly 3 during rotation. Moreover, the concealed plug-in portion 331 within the slot 3101 on the door panel 31 enhances the overall aesthetics of the air deflector assembly 3.

[0055] In some embodiments, such as Figures 2-3 As shown, the bearing seat 32 includes a first bearing seat 32A.

[0056] like Figures 4-6 As shown, the first bearing 32A includes: a first bearing plate 323 and a second bearing plate 324, as... Figure 6 and Figure 8 As shown, the first base plate 323 is provided with a first half-hole 3231, one end of the first base plate 323 is connected to the door panel 31, and the first half-hole 3231 has an opening at the end away from the door panel 31. The second base plate 324 is provided with a second half-hole 3241, one end of the second base plate 324 is connected to the door panel 31, and the second half-hole 3241 has an opening at the end facing the door panel 31.

[0057] The first base plate 323 and the second base plate 324 are connected, and the first half hole 3231 and the second half hole 3241 are arranged along the axial direction of the rotating shaft 333 to form the assembly hole 321.

[0058] In other words, this application substantially divides the traditional circular mounting hole on the first bearing 32A into two semi-circular holes, namely the first semi-hole 3231 and the second semi-hole 3241. Of course, the center angles of both the first semi-hole 3231 and the second semi-hole 3241 can be 180 degrees, or they can fluctuate slightly above or below 180 degrees; for example, the center angle of the first semi-hole 3231 can be 150 degrees, and the center angle of the second semi-hole 3241 can be 120 degrees. This design facilitates both assembly and machining.

[0059] It should be noted that in some existing solutions, the mounting hole on the bearing seat of the air guide plate is also a half-hole to facilitate the assembly of the shaft and bearing seat, allowing the shaft to be inserted along the opening of the half-hole during assembly. However, this half-hole only serves a positioning function and does not provide support or constraint for the shaft. In this way, the entire shaft is essentially in a cantilever state, resulting in low stability and making it prone to shaking and noise during airflow.

[0060] Compared to this solution, the present application uses two half-holes, which can guide the assembly by opening the half-holes, and the assembly hole 321 is formed by the first half-hole 3231 and the second half-hole 3241, which radially constrains the rotating shaft 333, so that the rotating shaft 333 is no longer cantilevered at this point, thereby improving stability and reducing the noise generated when the airflow passes through.

[0061] In other existing solutions, to achieve full constraint on the shaft, two spaced-apart bearings are used, each with a full-hole for mounting the shaft. This method is simple in design, but presents certain difficulties in machining.

[0062] Specifically, conventional air guide plates are injection molded. The shaft seat on the air guide plate needs to be machined with mounting holes, requiring consideration of demolding at these holes. That is, a mold shaft needs to be installed on the injection mold at the mounting hole. During demolding, the mold shaft is pulled out of the formed mounting hole on the air guide plate. Considering the direction of mold shaft removal, the upper mold of the air guide plate, being connected to the mold shaft, also needs to be demolded in this direction. This results in a texture on the air guide plate extending axially along the mounting hole. The direction of the texture extension is perpendicular to the airflow direction, increasing airflow resistance.

[0063] In this application, the mounting hole 321 on the first bearing 32A is divided into a first half-hole 3231 and a second half-hole 3241, and the demolding direction of the mold at the hole is no longer limited to the axial direction. In other words, there is a greater range of choices for the demolding direction at the half-hole, so the texture design on the door panel 31 no longer needs to consider axial line textures, and the texture design of the door panel 31 can have more flexible and aesthetically pleasing options.

[0064] In this application, the first bearing seat 32A is divided into a first bearing plate 323 and a second bearing plate 324. The contact area between the two bearing plates and the rotating shaft 333 after they are combined is larger than the contact area between a single bearing plate and the rotating shaft 333, which facilitates a more stable positioning of the rotating shaft 333. Moreover, the semi-hole design makes the first bearing seat 32A easier to demold, thereby improving the production efficiency of the air guide valve assembly 3.

[0065] Specifically, such as Figure 6 and Figure 8As shown, the first seat plate 323 is a sheet body, and the thickness of at least a portion of the first seat plate 323 gradually decreases in the direction away from the door panel 31. The thickness of the first seat plate 323 is the dimension of the first seat plate 323 along the axial direction of the rotating shaft portion 333.

[0066] Understandably, the first half-hole 3231 opens on the side away from the door panel 31, and the supporting function of the first seat plate 323 on the side away from the door panel 31 gradually diminishes. Therefore, by gradually thinning at least a portion of the first seat plate 323 in the direction away from the door panel 31, the supporting function of the first seat plate 323 on the pivot 333 is not affected, and the wind resistance during airflow is reduced. Moreover, the first seat plate 323 forms a slope at the thinning point, making the design more aesthetically pleasing.

[0067] Optionally, such as Figure 3 and Figure 8 As shown, the door panel 31 is provided with a demolding groove 3103, and the opening of the second half hole 3241 on the second seat plate 324 is set directly opposite the demolding groove 3103.

[0068] It is understandable that the opening of the second half hole 3241 on the second seat plate 324 faces the door plate 31. The demolding groove 3103 is set here to reduce the restriction of the door plate 31 when demolding the second half hole 3241, thereby improving the molding rate.

[0069] In some embodiments, such as Figure 4 and Figure 6 As shown, the bearing seat 32 includes a second bearing seat 32B, which includes a third bearing plate 325 and a fourth bearing plate 326.

[0070] The third seat plate 325 is connected to the door panel 31 at one end, and has an assembly hole 321. The fourth seat plate 326 is connected to the side of the third seat plate 325 facing the slot 3101, and has a receiving hole 3261 that communicates with the assembly hole 321. At least a portion of the connecting part 335 is inserted into the receiving hole 3261.

[0071] By inserting at least a portion of the connecting part 335 into the receiving hole 3261, a larger contact area can be formed between the connecting part 335 and the second bearing 32B, further improving the reliability and stability of the connection. Moreover, by concealing the connecting part 335 within the receiving hole 3261 on the second bearing 32B, the overall appearance of the air guide damper assembly 3 can be made more aesthetically pleasing.

[0072] Specifically, such as Figure 8As shown, the receiving hole 3261 has an opening on the side facing the door panel 31, and the receiving hole 3261 is connected to the slot 3101. This allows the connection between the connecting part 335 and the insertion part 331 to be concealed at the connection between the receiving hole 3261 and the slot 3101, further increasing the reliability and stability of the connection, and further improving the overall aesthetic appearance.

[0073] like Figure 8 As shown, the second bearing 32B also includes a retaining rib 327, which is located on the side of the fourth bearing plate 326 facing the slot 3101. The retaining rib 327 can be secured to the side of the connecting part 335 and also to the insertion part 331. This ensures that after the insertion part 331 is inserted, the retaining rib 327 prevents it from easily detaching from the slot 3101, thus improving the stability of the insertion part 331 within the slot 3101.

[0074] In some embodiments, such as Figure 8 As shown, the slot 3101 is provided with two pressure rods 3102. Each pressure rod 3102 extends along the length of the door panel 31, and the two pressure rods 3102 are arranged at intervals along the width of the door panel 31.

[0075] like Figure 7 As shown, the insertion part 331 includes: an insertion plate 3314, a socket 3315, and two claws 3316. The insertion plate 3314 is disposed on two pressure rods 3102 and connects to the connecting part 335. The socket 3315 is disposed on the insertion plate 3314 and is located between the two pressure rods 3102. The two claws 3316 are connected to opposite sides of the socket 3315, with each claw 3316 located on the side of the pressure rod 3102 away from the insertion plate 3314.

[0076] With this configuration, when the pin shaft 33 needs to be installed, the insertion part 331 can be pressed into the slot 3101. The claws 3316 on the socket 3315 press against the two pressure rods 3102, causing the pressure rods 3102 to bend and deform, increasing the distance between them, so that the claws 3316 can be inserted into the slot 3101. When the claws 3316 reach the side of the pressure rod 3102 away from the insertion plate 3314, the pressure rod 3102 returns to its original shape, thus locking the two claws 3316.

[0077] The structure of the plug part 331 in this application makes the connection very stable after the plug part 331 is inserted into the slot 3101, which is not easy to disengage and has high reliability. Moreover, the assembly method is relatively simple.

[0078] Optionally, one pressure bar 3102 is provided with a latching protrusion 3104 facing the other pressure bar 3102. Or, as Figure 8As shown, each of the two pressure rods 3102 has a locking protrusion 3104 on its side facing each other. The locking protrusion 3104 further reduces the distance between the two pressure rods 3102 at the locking protrusion 3104, making it less likely for the two claws 3316 to disengage from between the two pressure rods 3102 even during shaking. This further improves the stability of the connection.

[0079] Specifically, at least a portion of the socket 3315 is located on the side of the latching protrusion 3104 facing the bearing 32. A portion of the socket 3315 is sandwiched between the second bearing 32B and the latching protrusion 3104, so that after the pin shaft 33 is assembled in place, the pin shaft 33 is prevented from moving away from the bearing 32, thus preventing the shaft portion 333 from dislodging from the mounting hole 321 on the bearing 32.

[0080] Specifically, such as Figure 3 As shown, a groove 3317 is provided on the insert plate 3314 to facilitate the movement of the pin shaft 33.

[0081] Specifically, to facilitate the movement of the pin pivot 33, a lever 3318 is provided on the insert plate 3314.

[0082] In some embodiments, such as Figure 3 and Figure 6 As shown, the door panel 31 includes: a first plate 315 and a second plate 316 connected together, the first plate 315 and the second plate 316 being stacked along the thickness direction of the door panel 31.

[0083] The bearing seat 32 is integrally formed on the first plate 315, and the slot 3101 is formed on the first plate 315 and is disposed through the thickness direction of the first plate 315. The second plate 316 is connected to the side of the first plate 315 away from the bearing seat 32.

[0084] The door panel 31 is divided into a first plate 315 and a second plate 316 and then connected. Individual plates are easier to process, especially when blind holes or grooves need to be set on the door panel 31. During processing, through holes or grooves can be machined on the first plate 315, and then the ends of the through holes or grooves can be sealed with the second plate 316. In this way, each hole or groove is easier to form.

[0085] By integrally forming the bearing seat 32 onto the first plate 315, the connection reliability is high and the assembly process is reduced.

[0086] The air conditioner 1000 according to an embodiment of the present invention includes an air guide damper assembly 3. Specifically, the air guide damper assembly 3 is disposed at the indoor air outlet 101 of the air conditioner 1000 to control the opening and closing of the air outlet 101 and guide the direction of airflow. The structure of the air guide damper assembly 3 has been described in the above embodiments and will not be repeated here. This results in an air guide damper assembly 3 with lower wind resistance and more stable operation.

[0087] Other components of the air conditioner 1000 according to the present invention, such as heat exchangers and fans, as well as its operation, are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
