Technical Field

[0001] The utility model relates to an air outlet of a motorhome air conditioner panel, in particular to a damper control mechanism for the air outlet of a motorhome air conditioner panel, which controls the opening and closing of the damper and the opening amplitude. Background Art

[0002] In a motorhome air conditioning system, the damper control mechanism of the panel air outlet is a key component, which directly affects the direction and air volume of the air blown out by the air conditioner, and thus affects the comfort of passengers. With the development of technology, the design and functional requirements for the damper control mechanism are also getting higher and higher.

[0003] Traditional damper control mechanisms for motorhome air conditioners often adopt a relatively simple mechanical design, and adjust the opening and closing angle of the damper by manual or motor drive to change the direction and air volume of the air blown out.

[0004] The vehicle air conditioner damper adjustment mechanism and the vehicle air conditioner air outlet structure of CN203628964U include an adjustment knob, a driving swing arm, and a damper. A driven swing arm that drives the damper to rotate under the drive of the driving swing arm is connected between the driving swing arm and the damper, and a gear connection mechanism that drives the driving swing arm to swing when the adjustment knob rotates is connected between the adjustment knob and the driving swing arm. When the adjustment knob rotates, relying on the meshing of two gears, there will be a sense of gear when turning the adjustment knob. In addition, the setting of the gears increases the structural complexity and inconvenience of installation; especially in the long-term vibration environment of the vehicle, the gear structure is prone to wear and looseness, which easily leads to the failure of the mechanism.

[0046] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0047] It should be noted that like reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it will not be further defined and explained in subsequent drawings.

[0048] As Figure 1 、 Figure 8 and Figure 9 shown, the air damper control mechanism 100 of the air outlet of the RV air conditioner panel is designed to provide precise and convenient control of the air direction and air volume for users. The mechanism mainly consists of the following parts: the air outlet frame 10, the air deflector 20, and the adjusting dial 30. The air outlet frame 10 is made of a strong and durable material, including side plates 40, which not only ensure the structural stability but also provide sufficient strength to support the entire mechanism.

[0049] The air outlet frame 10 adopts a streamlined design to reduce the resistance during air flow and optimize the aerodynamic performance of the air damper control mechanism. The rotating shaft 21 of the air deflector 20 allows the air deflector 20 to rotate freely within a certain angle range to adjust the air flow direction of the air outlet.

[0050] As Figure 3 、 Figure 4 、 Figure 5 shown, an end of the air deflector 20 is provided with a rotating shaft 21. The adjusting dial 30 includes a dial surface 32 and at least one side wall 31. The dial surface 32 provides a wide contact surface, enabling users to easily control the angle of the air deflector through a rotating motion. Each side wall 31 is provided with a shaft connection hole 33 and an elastic member 34 extending towards the side plate 33. A damping plane 41 and a groove 42 recessed in the damping plane 41 are provided on a side surface of the side plate 40 close to the adjusting dial 30; the rotating shaft 21 of the air deflector 20 passes through the side plate 40 and is inserted into the shaft connection hole 33 of the adjusting dial 30.

[0051] These elastic members 34 act as buffers and positioning devices during the adjustment process. When the adjustment dial 30 is turned, they move from the groove 42 to the damping plane 41, or from the damping plane 41 back to the groove 42, thereby ensuring stable control of the air deflector 20. The damping prevents mechanical damage to various components caused by rapid or drastic adjustments. When the elastic members 34 precisely fit into the groove 42 on the side panel 40, the air deflector 20 is stably positioned in the first position, closing the air outlet g. This ensures that the air outlet g remains closed, thus achieving airflow control.

[0052] By turning the adjustment dial 30, the elastic member 34 is released from the groove 42 and moves onto the damping plane 41. During this process, the end of the elastic member 34 has damping properties, allowing it to move smoothly on the damping plane 41 without sudden or drastic changes in position. This damping effect not only helps reduce the mechanical stress caused by rapid movement but also provides a gentle adjustment mechanism, allowing the user to experience smooth feedback when adjusting the wind deflector 20.

[0053] The damping effect between the end of the elastic member 34 and the damping plane 41 further ensures that the air deflector 20 remains stable in at least one pre-set second position. This technical approach allows the user to select different airflow directions and volumes as needed. In this way, the air deflector 20 can achieve precise adjustment of multiple rotation ranges, providing users with a highly customized airflow experience.

[0054] More specifically, if Figure 3 As shown, the side plate 40 is a key component of the damper control mechanism 100. It consists of a fixed plate a and an assembly gland b. This structure not only provides stable support but also allows for quick and convenient assembly and maintenance. The shaft hole a1 in the fixed plate a is specifically designed for the rotating shaft 21, ensuring smooth rotation of the air deflector 20 about the shaft. The open area a2 below the shaft hole a1 is an ingenious technical feature that provides the necessary space for installation and adjustment of the air deflector 20.

[0055] The hook groove a3 on the fixed plate a is designed to tightly mate with the mounting cover b. The mounting cover b hooks into the hook groove a3 via its hook foot b2. This structure not only ensures the secure assembly of the side panels but also provides a simple and effective connection method. The presence of the top post b3 is also thoughtful. It extends into the open area a2 and supports the rotating shaft 21, providing stable support for the shaft and ensuring smooth movement of the air deflector 20 during operation.

[0056] In addition, if Figure 7As shown, the assembly gland b further includes an extension b4 on one side of the base b1. The extension b4 has a lower limit edge b5, and the adjustment dial 30 has a lower limit end 35. The lower limit edge b5 and the lower limit end 35 cooperate to limit the maximum opening amplitude of the air deflector 20.

[0057] The cooperation between the extension b4 and the lower limit edge b5 of the assembly gland b, which mates with the lower limit end 35 of the adjustment dial 30, not only limits the maximum opening amplitude of the air deflector 20 but also ensures the accuracy and reliability during the adjustment process. Thus, by controlling the opening angle of the air deflector 20, the air flow distribution at the air outlet of the air conditioner is further optimized, improving the efficiency of the air conditioning system and the comfort of users.

[0058] As Figure 6 shown, the first side of the air outlet frame 10 is equipped with a lower limit rib a1 to ensure tight fit on its first side when the air deflector 20 is closed, achieving sealing and precise positioning. The second side of the air outlet frame 10 is provided with a limit cross plate a2.

[0059] In the closed state of the air deflector 20, its first side realizes precise closing position control through interaction with the lower limit rib a1. At the same time, the upper limit rib a3 formed by the outward extension of the second side of the air deflector 20 cooperates with the limit cross plate a2 to jointly limit the maximum closing amplitude of the air deflector 20. This two-way limit design ensures the tightness and consistency of the air deflector when closed and also provides a basis for precise adjustment in the open state.

[0060] Preferably, both the limit cross plate a2 and the upper limit rib a3 are inclined plates, and their inclination amplitudes match, thereby improving the stability of the air deflector in both the closed and open states, and also helping to enhance its structural strength, making it more resistant to deformation that may occur during long-term operation or in extreme environments.

[0061] In addition, the interaction between the upper limit rib a3 of the air deflector 20 and the inclined limit cross plate a2 not only functions in the closed state but also provides stable angular support when the air deflector 20 is opened, ensuring precise control of the air flow direction. This design that comprehensively utilizes limit ribs and limit cross plates significantly improves the operation accuracy and reliability of the air damper control mechanism, and also optimizes the efficiency and uniformity of the air output of the air conditioner.

[0062] In summary, the interaction and limit settings between the air outlet frame 10 and the air deflector 20 together constitute an efficient and precise air damper control system, which not only ensures the sealing performance of the air outlet of the air conditioner but also improves the flexibility and accuracy of adjustment, providing users with a more comfortable and controllable air conditioning experience.

[0063] More specifically, the adjustment dial 30 is composed of two side walls 31 and a dial surface 32 connecting these two side walls. This structure forms a solid framework and provides a stable operating platform. The interval between the side walls 31 reduces the weight of the dial. The tooth pattern design on the dial surface 32 provides excellent grip, ensuring that even when the hands are wet or stained, users can firmly hold and operate the dial. In addition, the tooth pattern also serves an aesthetic purpose and enhances the detailed texture of the product.

[0064] The elastic member 34 is a cantilever c. There is a vacant position 36 on the side wall 31. The cantilever c includes a connecting column c1 within the vacant position 36 and a transverse portion c2 extending towards the side plate 40 with a pressing end c3. The elastic members 34 on the side walls are symmetrically distributed. The connecting column c1 of the cantilever c is located within the vacant position 36 on the side wall 31. This technical means allows the elastic member 34 to move precisely without restriction. The transverse portion c2 of the cantilever c extends towards the side plate 40 and has a pressing end c3. The pressing end c3 cooperates with the damping plane 41 through a damping effect to achieve the opening and closing adjustment of the air deflector 20.

[0065] Preferably, the upper end surface of the top post b3 is an arc-shaped concave surface to fit the arc-shaped surface of the rotating shaft 21. Thus, it is ensured that there is a constant contact area between the top post b3 and the rotating shaft 21. The arc-shaped concave surface can provide a stable support point to ensure that the rotating shaft 21 remains stable when bearing force and reduce displacement caused by vibration or impact. In addition, the arc-shaped concave surface helps to disperse stress and reduce wear caused by friction, thereby extending the service life of the rotating shaft 21 and the top post b3.

[0066] As Figure 1 、 Figure 8 and Figure 9 shown, the preferred installation method of the air damper control mechanism in this embodiment is as follows: An installation seat R is provided in the middle area of the bottom surface of the air outlet face frame 10. On both sides of the installation seat R are air outlets with the same opening size. The adjustment dial 30 is installed on the installation seat R, and an installation cover P is provided outside the installation seat R; Two air deflectors 20 are respectively installed on both sides of the installation seat R. By adjusting the adjustment dial 30 at the middle position, the simultaneous adjustment of the two air deflectors 20 can be achieved.

[0067] The installation seat R includes two fixed plates a provided at an interval. A shaft hole a1 for the rotating shaft 21 to pass through is opened in the middle of the fixed plate a. The lower side of the shaft hole a1 is an open area a2 to facilitate the assembly of the air deflector 20; On one side of the fixed plate a close to the adjustment dial 30, there is a damping plane 41 and a groove 42 recessed in the damping plane 41 to be in damping cooperation with the elastic member 34.

[0068] On both sides of the fixed plate a, there are hook grooves a3, and the surface of the hook groove a3 is an inclined surface for easy assembly; the installation cover P includes two assembly pressing covers b arranged at an interval, and the assembly pressing cover b includes a base b1, two hook feet b2, and a top column b3; the hook feet b2 hook the hook grooves a3 to connect the assembly pressing cover b to the fixed plate a, and the top column b3 extends into the open area a2 and abuts against the rotating shaft 21.

[0069] There is a transverse connecting extension b4 between the two assembly pressing covers b. The extension b4 has a lower limit edge b5. The adjusting dial 30 has a lower limit end 35. The lower limit edge b5 and the lower limit end 35 cooperate to limit the maximum opening amplitude of the air deflector 20.

[0070] In addition, the transverse distance between the assembly pressing covers b is greater than the thickness of the adjusting dial 30 so that the adjusting dial 30 can rotate freely. The bottom surface of the extension b4 is provided with a vertical reinforcing plate b7 to improve the strength of the assembly pressing cover b. The rest of the more detailed technical details and technical effects have been elaborated in detail above and will not be repeated here.

[0071] Preferably, rubber pads are provided on both the lower limit rib a1 and the limit horizontal plate a2 to reduce the impact noise when the air deflector 20 is closed.

[0072] Preferably, as Figure 2 and Figure 9 shown, at least a part of the adjusting dial 30 is exposed outside the air outlet surface frame 10. The exposed adjusting dial 30 is convenient for users to operate, improving the convenience and intuitiveness of the operation. And on both sides of the exposed adjusting dial 30, there are straight guiding walls 11. The straight guiding walls 11 provide physical guidance to ensure that users can smoothly rotate the dial along a predetermined direction during operation, reducing the possibility of misoperation.

[0073] In addition, direction guiding arrows 12 are engraved on the upper side of the air outlet surface frame 10 between the straight guiding walls 11. It provides clear visual cues for users, and the coordinated cooperation of the straight guiding walls 11 and the direction guiding arrows 12 enhances the interaction experience between users and the product.
