Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to an automotive air conditioning damper actuator. Background Technology

[0002] The automotive air conditioning damper actuator, as an accessory to the air conditioning system, is one of the essential components of modern automobiles. Its main function is to change the airflow direction of the air vents inside the vehicle by adjusting the position and angle of different air dampers according to the different airflow needs of the occupants.

[0003] Patent publication number CN221188033U discloses an automotive air conditioning damper actuator, including a housing with an upper-opening mounting cavity. A gear set and a drive motor are housed within the mounting cavity. A worm gear for driving the gear set is connected to the output shaft of the drive motor. The worm gear is sleeved outside the output shaft, with the free end of the output shaft extending through the worm gear. The free end of the output shaft and the end of the drive motor are respectively connected to the inner wall of the mounting cavity. A support frame is provided on the motor housing of the drive motor. The end of the support frame away from the motor housing extends axially along the output shaft, and the end of the output shaft extending through the worm gear is rotatably connected to the support frame. This automotive air conditioning damper actuator, through improvements to the motor output shaft end, ensures stable operation of the motor output shaft and reduces noise during operation, thus lowering production costs. However, the motor generates heat during operation; if this internal heat is not dissipated quickly, excessively high temperatures will reduce the motor's lifespan. Summary of the Invention

[0004] To address the issue mentioned above where motors generate heat during operation, and the high temperature reduces motor lifespan if the internal heat is not dissipated quickly, this invention provides an automotive air conditioning damper actuator.

[0005] This utility model provides an automotive air conditioning damper actuator, which adopts the following technical solution:

[0006] An automotive air conditioning damper actuator includes a housing, a motor mounted on the inner bottom wall of the housing, a worm gear mounted on the top of the motor, a gear set meshing with the right side of the worm gear, a mounting frame mounted on the top of the housing, a horizontal plate mounted on the lower end of the inner cavity of the mounting frame, and rotating rods rotatably connected to both ends of the bottom of the horizontal plate. Fan blades are mounted on the bottom of both sets of rotating rods, and a rotating rod drive structure is provided on the top of the two sets of rotating rods.

[0007] By adopting the above technical solution, when the motor is started, it drives the worm gear to rotate, which in turn drives the gear set to rotate. The motor generates a certain amount of heat when it is working. Through the rotating rod drive structure, it can drive two sets of rotating rods and fan blades to rotate simultaneously to generate suction. The suction draws outside air into the mounting frame and then blows the air into the housing to dissipate heat from the motor inside the housing, thus extending the motor's service life.

[0008] Optionally, a rubber sleeve is fitted onto the outside of the motor.

[0009] By adopting the above technical solutions, noise, vibration and impact can be absorbed and consumed, minimizing the impact of noise on passengers inside the vehicle.

[0010] Optionally, the mounting frame has openings at both the top and bottom.

[0011] By adopting the above technical solution, it is possible to ensure that outside air can enter the interior of the housing through the mounting frame.

[0012] Optionally, the rotating rod drive structure includes two sets of upright plates, which are respectively installed at both ends of the top of the horizontal plate. A shaft tube is rotatably connected between the two sets of upright plates. A motor for driving the shaft tube to rotate is installed on the outer side of the right-end upright plate. Both ends of the outer wall of the shaft tube are fitted with bevel gear one. The bottom of both sets of bevel gear one are meshed with bevel gear two. The bottom of both sets of bevel gear two are connected to a drive rod, and the bottom of the drive rod is fixedly connected to the top of the rotating rod.

[0013] By adopting the above technical solution, when the motor is working, it drives the shaft tube to rotate, the shaft tube to rotate, the first bevel gear to rotate, the first bevel gear to rotate, and the second bevel gear to rotate, which in turn drives the rotating rod and fan blades to rotate, thereby ventilating and cooling the motor inside the housing.

[0014] Optionally, a dustproof net is installed on the top of the inner cavity of the mounting frame, and a dustproof net disassembly and assembly structure is provided between the dustproof net and the mounting frame.

[0015] By adopting the above technical solution, dust is effectively reduced by blocking external dust through the dustproof net, thus reducing the amount of dust entering the interior of the casing.

[0016] Optionally, the dustproof net assembly / disassembly structure includes two sets of grooves, which are respectively opened at both ends of the top of the mounting frame. The inner walls of the two sets of grooves are connected to springs. Movable plates are installed on the side of the two sets of springs near the dustproof net. Insert blocks are connected to the end of the two sets of movable plates away from the springs. Slots that engage with the insert blocks are opened on both sides of the dustproof net.

[0017] By adopting the above technical solution, when it is necessary to disassemble the dustproof net, pull the moving plate to move it and squeeze the spring. When the moving plate moves, it drives the insert block to move until the insert block separates from the slot, releasing the fixing effect of the insert block on the dustproof net. Then, pull the dustproof net upward to disassemble it for cleaning or replacement.

[0018] Optionally, the inner wall of the mounting frame is equipped with baffles, and there are two baffles arranged alternately.

[0019] By adopting the above technical solution, the sound waves will be refracted and dissipated by the two baffles, thereby achieving a further noise reduction effect while ensuring ventilation.

[0020] In summary, this utility model has at least one of the following beneficial effects:

[0021] By combining the rotating rod, fan blades, cross plate, and rotating rod drive structure, suction is generated by driving the rotating rod and fan blades to rotate. This suction draws outside air into the mounting frame, which then blows the air into the housing to cool the motor inside, thus extending the motor's lifespan.

[0022] The dust filter helps to filter the air, preventing dust from entering the housing and contaminating the motor and gear assembly. The dust filter's detachable design also allows for easy regular disassembly and cleaning, preventing clogging over time. Attached Figure Description

A mounting frame 1 is fixedly mounted on the top of the housing 4, and openings are provided at both the top and bottom of the mounting frame 1. This ensures that outside air can enter the interior of the housing 4 through the mounting frame 1. Two baffles 9 are fixedly mounted on the inner wall of the mounting frame 1, and the two baffles 9 are arranged alternately. Sound waves will be refracted and dissipated by the two baffles 9, thereby achieving a noise reduction effect while ensuring ventilation.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2A dustproof net 11 is detachably installed on the top of the inner cavity of the mounting frame 1, and a dustproof net disassembly and assembly structure 13 is provided between the dustproof net 11 and the mounting frame 1. The dustproof net 11 blocks external dust, effectively reducing the amount of dust entering the interior of the housing 4. The dustproof net disassembly and assembly structure 13 includes two sets of grooves 1305, which are respectively opened at both ends of the top of the mounting frame 1. Springs 1304 are fixedly connected to the inner walls of both sets of grooves 1305. Movable plates 1303 are fixedly installed on the side of both sets of springs 1304 near the dustproof net 11. Insert blocks 1302 are fixedly connected to the end of both sets of movable plates 1303 away from the springs 1304. Slots 1301 that engage with the insert blocks 1302 are opened on both sides of the dustproof net 11. When it is necessary to remove the dustproof net 11, pull the moving plate 1303 to move and squeeze the spring 1304. When the moving plate 1303 moves, it drives the insert block 1302 to move until the insert block 1302 separates from the slot 1301, releasing the fixing effect of the insert block 1302 on the dustproof net 11. Then pull the dustproof net 11 upward to remove it and clean or replace it.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 3 A horizontal plate 10 is installed at the lower end of the inner cavity of the mounting frame 1. Both ends of the bottom of the horizontal plate 10 are rotatably connected to rotating rods 2. Fan blades 3 are installed at the bottom of both sets of rotating rods 2. A rotating rod drive structure 12 is provided at the top of the two sets of rotating rods 2. The rotating rod drive structure 12 includes two sets of vertical plates 1202. The two sets of vertical plates 1202 are respectively vertically installed at the top ends of the horizontal plate 10. A shaft tube 1203 is rotatably connected between the two sets of vertical plates 1202. A motor 1201 for driving the shaft tube 1203 to rotate is installed on the outer side of the right end vertical plate 1202. Both ends of the outer wall of the shaft tube 1203 are fixedly sleeved with bevel gear 1204. The bottoms of the two sets of bevel gear 1204 are meshed with bevel gear 1205. The bottoms of the two sets of bevel gear 1205 are fixedly connected with drive rods 1206, and the bottom of the drive rod 1206 is fixedly connected to the top of the rotating rod 2. When the motor 1201 is working, it drives the shaft tube 1203 to rotate. The rotation of the shaft tube 1203 drives the first bevel gear 1204 to rotate. The rotation of the first bevel gear 1204 drives the second bevel gear 1205 to rotate. In turn, the drive rod 1206 drives the rotating rod 2 and the fan blade 3 to rotate, so as to ventilate and dissipate heat from the motor 6 inside the housing 4.

[0033] Working principle: When in use, the motor 6 is started. When the motor 6 is working, it drives the worm gear 5 to rotate. The rotation of the worm gear 5 drives the gear set 8 to rotate. By attaching a rubber sleeve 7 to the outside of the motor 6, noise, vibration and impact can be absorbed, minimizing the impact of noise on passengers in the vehicle. The motor 6 generates a certain amount of heat when it is working. At this time, the motor 1201 is started. When the motor 1201 is working, it drives the bevel gear 1204 to rotate through the shaft tube 1203. The rotation of the bevel gear 1204 drives the bevel gear 1205 to rotate. The rotation of the bevel gear 1205 drives the drive rod 1206 to rotate, which in turn drives the two sets of rotating rods 2 and the fan blades 3 to rotate simultaneously to generate suction. The suction draws outside air into the mounting frame 1 and then blows the air into the housing 4 to dissipate heat from the motor 6 inside the housing 4, thus improving the service life of the motor 6.

[0034] The dustproof net 11 can block external dust. When a lot of debris accumulates on the dustproof net 11, the staff can push the moving plate 1303 to move and squeeze the spring 1304. As the moving plate 1303 moves, it drives the insert block 1302 to move until the insert block 1302 separates from the slot 1301, releasing the fixing effect of the insert block 1302 on the dustproof net 11. Then, the dustproof net 11 can be pulled upward to remove it from the inside of the mounting frame 1 for cleaning or replacement, thus avoiding the dustproof net 11 from becoming clogged after long-term use.

[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
