The first boss can be inserted into the first annular groove and a first sealing structure is arranged between the two, which can form a first effective seal for the interior of the damper actuator. In addition, a first recessed groove is arranged on the outer periphery of the first annular groove, a second boss is also arranged on the outer periphery of the first boss, and the second boss is matched with the first recessed groove and plugged in, and a second sealing structure is arranged between the two, thereby effectively forming a second effective seal on the periphery of the first sealing structure, effectively providing two sealing and waterproof structures, thereby effectively improving the sealing and waterproof effect of the damper actuator; it can effectively solve the problem in the prior art that the damper actuator of the vehicle air conditioner has rain leakage or water leakage, which causes the damper actuator to short-circuit and burn out, resulting in air conditioning failure.

[0051] The present invention proposes a damper actuator with waterproof function and its air conditioner. When the damper actuator is used, the protection level of the electric execution of the damper can be effectively improved, so that when the vehicle is driving in severe weather such as strong winds and heavy rain, even if rain and other liquids splash onto the damper actuator, the normal operation of the damper can be guaranteed, thereby ensuring that the interior space of the vehicle can be normally supplied with air, ventilated, cooled and heated during parking, providing a layer of safety protection for the safety of the driver and passengers, avoiding serious casualties such as stuffiness, cold, lack of oxygen and suffocation of the driver or passengers, ensuring the normal use of vehicle-related functions such as air conditioning, and ensuring the personal safety of the driver and passengers.

[0052] The present invention provides a damper actuator with waterproof function and air conditioner thereof, the damper actuator includes an upper shell cover assembly, a lower shell cover assembly, an intermediate plate, a gear and other parts;

[0053] Upper shell cover (first shell cover), ① Material characteristics, the upper shell cover material is a non-metallic material with a certain strength, such as polyester, nylon, etc., which is not only the external frame support structure of the damper actuator, but also reduces the weight of the damper actuator, which is beneficial to reducing the weight of the vehicle and indirectly plays a role in energy conservation and emission reduction; ② Structural characteristics, an irregular groove (first sinking groove 3) is provided on the upper shell cover, and the groove is approximately annular in structure, which is used to place the sealing ring, and after cooperation, it plays a sealing role such as waterproof and dustproof; ③ Another V-shaped groove (i.e., the first annular groove 6) is provided on the upper shell cover, and the groove is approximately annular in structure, which is used to place the sealing ring, and after cooperation, it plays a double sealing role such as waterproof and dustproof, and the number of grooves can also be one or more; ④ The outer periphery of the upper shell cover extends longer, forming a stepped structure with the lower shell cover, which to a certain extent blocks the flow of liquid from penetrating into the interior of the damper actuator; ⑤ A number of approximately cylindrical columnar positioning columns are provided on the upper shell cover, which play the role of pre-positioning the intermediate plate.

[0054] The lower cover assembly (second cover assembly) has the following characteristics: 1. Material: The lower cover is made of a strong non-metallic material, such as polyester or nylon. It serves as the external frame support structure for the damper actuator and reduces the weight of the damper actuator, which helps reduce vehicle weight and indirectly contributes to energy conservation and emission reduction. 2. Structural: The lower cover assembly is equipped with an irregular boss (i.e., the second boss 16). This boss corresponds to the groove in the upper cover and forms a nearly annular structure. It compresses the sealing ring and, when engaged, provides a waterproof and dustproof sealing effect. 3. The lower cover assembly is equipped with another V-shaped boss (the first boss 18). This boss corresponds to the V-shaped groove in the upper cover and forms a nearly annular structure. It compresses the sealing ring and, when engaged, provides a dual waterproof and dustproof sealing effect. The number of bosses can be one or more. 4. A hollow column protruding axially is provided on the shaft of the lower cover assembly. This column, in conjunction with the hollow column in the shaft hole of the upper volute, forms a double layer to prevent liquid from splashing directly onto the shaft and flowing along the shaft into the damper actuator.

[0055] In some embodiments, the first housing 1 is provided with a third boss 7 and a fourth boss 8. The fourth boss 8 is located on the outer periphery of the first cavity 4, and the third boss 7 is located on the outer periphery of the fourth boss 8. The first annular groove 6 is formed between the third boss 7 and the fourth boss 8. Both the third boss 7 and the fourth boss 8 are annular bosses. This is the preferred structural form for forming the first annular groove of the present invention, i.e., an annular first annular groove is formed between the two annular bosses.

[0056] In some embodiments, a positioning post 5 is protruding from the inner circumferential wall of the fourth boss 8; an intermediate plate 12 is disposed within the first cavity 4 of the first housing cover 1, and a positioning notch 13 is disposed on the outer circumference of the intermediate plate 12. The positioning notch 13 can be engaged with the positioning post 5 in a one-to-one manner. The present invention also utilizes the positioning posts disposed on the inner wall of the fourth boss and the positioning notch disposed on the outer circumference of the intermediate plate to form a snap fit between the positioning posts and the positioning notch, thereby providing positioning and guidance for the installation of the intermediate plate.

[0057] In some embodiments, the cross-sectional shape of the first annular groove 6 at any position is V-shaped, the cross-sectional shape of the first boss 18 at any position is V-shaped, and the V-shaped first boss 18 is adapted to the shape of the V-shaped first annular groove 6. The first sealing structure 11 is an annular sealing ring, and the cross-sectional shape of the first sealing structure 11 at any position is also V-shaped, and the V-shaped first sealing structure 11 is adapted to the shape of the V-shaped first annular groove 6. The present invention can further form a secure clamping arrangement between the V-shaped first boss and the V-shaped first sealing structure, and the V-shaped first boss further secures the sealing ring, thereby increasing the preload force of the sealing ring and further improving the sealing effect.

[0058] Sealing ring and V-shaped sealing ring, ① Material characteristics, the material of the sealing ring and V-shaped sealing ring is rubber or other non-metallic materials with certain elasticity. When subjected to external forces such as extrusion, they will undergo elastic deformation, and cooperate with the groove on the upper shell cover assembly and the boss on the lower shell cover assembly to play a sealing role such as waterproof and dustproof; the sealing ring and the V-shaped sealing ring can be the same material or different materials; ② Shape characteristics, the sealing ring corresponds to the shape of the groove on the upper shell cover assembly, and is an approximately ring-shaped structure. The front and back of the sealing ring are the same, and there is no need to distinguish between the front and back during installation. The operation is simple and efficient; the V-shaped sealing ring corresponds to the V-shaped groove on the upper shell cover assembly and the V-shaped boss on the lower shell cover assembly, and is an approximately ring-shaped structure as a whole.

[0059] In some embodiments, the second housing further includes a second annular groove 17 formed on the outer periphery of the first boss 18. The second housing of the present invention has a second annular groove formed on its outer periphery through the first boss, so that the second annular groove can cooperate with the third boss to achieve a better sealing and waterproof effect.

[0060] In some embodiments, the bottom of the first trough 3 is provided with a first mounting hole 2 in a through-hole manner, and the surface of the second boss 16 facing the first trough 3 is also provided with a second mounting hole 19 in a through-hole manner, with the first mounting hole 2 and the second mounting hole 19 being provided in a one-to-one correspondence; the second sealing structure 9 is an annular sealing ring structure, and a third mounting hole 10 is provided in a position opposite to the first mounting hole 2 on the first trough 3. The mounting holes respectively provided in the first trough and the second boss of the present invention can effectively connect and fasten the first shell cover and the second shell cover, and because the mounting holes pass through the position where the second sealing structure is located, a fourth mounting hole is provided in the second sealing structure to effectively accommodate a fastener passing therethrough, thereby effectively fastening the first and second shell covers and the sealing structure together, further improving the sealing and waterproofing effect.

[0061] In some embodiments, the drive mechanism includes a motor, the transmission mechanism includes two or more gear structures, and the damper actuator further includes an output shaft, namely a gear shaft 21. One end of the gear shaft 21 extends into the second housing to connect with the transmission mechanism, and the other end extends out of the second housing in a direction away from the first housing 1. The present invention also effectively outputs the power of the damper actuator outwardly through the gear shaft, thereby controlling the damper, specifically opening or closing it or adjusting the opening angle.

[0062] The present invention further provides a volute assembly comprising the damper actuator described in any of the preceding items, further comprising a first volute 27 and a second volute 35, wherein the first volute 27 and the second volute 35 are connected, and the damper actuator 20 is disposed on the first volute 27 to drive the damper in the volute assembly via the damper actuator 20.

The present invention also uses the structure of the first hollow column on the first volute and the second hollow column of the second shell cover assembly to enable the second hollow column to be effectively inserted into the first axial hole of the first hollow column, and the gear shaft is passed through the second axial hole to the first axial hole, which can further effectively seal the damper actuator at the position of the output shaft (gear shaft), further improving the waterproof effect of the damper actuator.

[0064] In some embodiments, the second volute 35 is provided with a third hollow column 371 having a hollow third axial hole 37. The third hollow column 371 protrudes toward the first volute 27 and is inserted into the first axial hole 29 of the first hollow column 30 and spaced a preset distance from the second hollow column 22. The axial length of the third hollow column 371 is less than the axial length of the first hollow column 30. The gear shaft 21 also passes through the third axial hole 37 of the third hollow column 371. The present invention also utilizes the third hollow column on the second volute to effectively insert the third hollow column into the first axial hole of the first hollow column. Furthermore, the gear shaft passes from the second axial hole to the first axial hole and then further into the third axial hole, thereby further effectively sealing the damper actuator at the output shaft (gear shaft), further improving the waterproofing effect of the damper actuator.

[0065] In some embodiments, when the bottom of the first sink 3 is provided with a first mounting hole 2 in a through-going manner, and the surface of the second boss 16 facing the first sink 3 is also provided with a second mounting hole 19 in a through-going manner:

The first threaded hole 31 is arranged opposite to the first mounting hole 2 and the second mounting hole 19. The mounting column is located on the outer periphery of the first hollow column 30.

[0067] The present invention can effectively cooperate with the mounting hole on the damper actuator through the structure of the mounting column, and can effectively fix the damper actuator to the first volute through the threaded fasteners, thereby improving the fastening effect of the damper actuator and further improving the waterproof effect of the damper actuator.

[0068] In some embodiments, a water baffle 28 is protruding from the volute body, connected to the mounting post and located above the first hollow post 30. The present invention further seals and waterproofs the damper actuator through the structure of the water baffle, thereby improving the waterproof effect.

[0069] Structural features of the upper volute (i.e., the first volute 27): ① A first axial hole 29 is provided on the upper volute, and a first hollow column 30 is provided on the outside of the axial hole, which is higher than a certain distance and cooperates with the second hollow column 22 on the damper actuator to prevent liquid from splashing onto the shaft, and further prevent the liquid from flowing into the damper actuator along the shaft; ② A water baffle is provided on the upper volute, and the water baffle is in a circular arc shape or an irregular arc shape, and is located at the upper end and bent downward.
