Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive air conditioning (HVAC) assembly technology, and particularly relates to an automotive air conditioning damper mechanism. Background Technology
[0002] The automotive air conditioning HVAC system is one of the most important components of a vehicle. HVAC is an abbreviation for Heating, Ventilation and Air Conditioning, which is responsible for providing a comfortable in-vehicle environment and optimizing the driver's driving experience during vehicle operation.
[0003] To adjust the temperature inside the vehicle more quickly, HVAC systems have air vents in various key locations inside the vehicle, including vents at the feet of passengers, known as foot vents. Common air conditioning structures use panel vents, with the front airflow and defrost modes sharing the same vent. This causes the foot vent to collide with the foot vent frame at the moment it closes during front airflow or defrost modes due to excessive air pressure, resulting in a banging sound.
[0004] Therefore, we propose an automotive air conditioning damper mechanism to solve the above problems. Summary of the Invention
[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an automotive air conditioning damper mechanism.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automotive air conditioning damper mechanism includes a housing, a central rod, and a damper. The central rod is disposed inside the housing, and the damper is rotatably connected to the side wall of the central rod. A damper is installed on the inner wall of the housing, with the telescopic end of the damper facing the damper. A fixing seat is fixedly disposed on the side wall of the damper, and an adjustment component for adjusting the position of the damper is installed on the side wall of the fixing seat facing the housing. The end of the damper facing away from the damper is rotatably connected to the side wall of the housing.
[0008] Preferably, the damper is 3mm away from the damper, and a buffer pad is provided on the top of the damper facing the damper.
[0009] Preferably, a rotating seat is fixedly provided on the side wall of the housing, and the side wall of the rotating seat is rotatably connected to the end of the damper facing away from the damper.
[0010] Preferably, the fixing base is fixedly connected to two brackets on the side wall facing the housing, the two brackets are arranged in parallel, and the side wall of the brackets is provided with sliding holes.
[0011] Preferably, the adjustment assembly includes an adjustment knob, a threaded rod, and a slide rod. A threaded hole is provided on the side wall of the housing. The threaded rod passes through the threaded hole and is threadedly connected to it. The adjustment knob is fixedly disposed at the end of the threaded rod away from the fixed seat. The end of the threaded rod away from the adjustment knob is rotatably connected to the side wall of the slide rod. The two ends of the slide rod are slidably connected to the inner walls of the sliding holes on the side walls of the two brackets, respectively.
[0012] Preferably, the slide rod is cylindrical, the width of the sliding hole is the same as the diameter of the slide rod, and the length of the slide rod is greater than the distance between the two supports.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] By adding a damper and a buffer pad to the housing, the damper can be buffered at the moment of closing, thereby eliminating the banging sound. It also reduces the need for changes to the housing, damper, and motion mechanism. The factory does not need to set up a new production line, and the cost of the added damper is relatively controllable. The cost of this application is low, the structure is simple, and it is more convenient to promote and use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] like Figure 1 - Figure 3As shown, an automotive air conditioning damper mechanism includes a housing 1, a central rod 2, and a damper 3. The central rod 2 is located inside the housing 1. The damper 3 is rotatably connected to the side wall of the central rod 2. A damper 4 is installed on the inner wall of the housing 1. The telescopic end of the damper 4 faces the damper 3. The distance between the damper 4 and the damper 3 is 3mm. A buffer pad 6 is provided on the top of the end of the damper 4 facing the damper 3. The buffer pad 6 can be made of rubber, sponge, etc. The buffer pad 6 is hemispherical. Therefore, no matter how the angle between the damper 4 and the damper 3 changes, it will not affect the buffering effect of the damper 4 on the damper 3.
[0021] A rotating seat 7 is fixedly installed on the side wall of the housing 1. The side wall of the rotating seat 7 is rotatably connected to the end of the damper 4 facing away from the damper 3. The end of the damper 4 facing away from the damper 3 is also rotatably connected to the side wall of the housing 1. The rotating seat 7 allows the damper 4 to rotate around the rotating seat 7, thereby allowing the buffer pad 6 to be adjusted to different angles to buffer the damper 3. A fixed seat 5 is fixedly installed on the side wall of the damper 4. Two brackets 8 are fixedly connected to the side wall of the fixed seat 5 facing the housing 1. The two brackets 8 are arranged in parallel. The side wall of the bracket 8 has a sliding hole 9. Figure 3 As can be seen, both ends of the sliding hole 9 are arc-shaped, which facilitates the sliding rod 12 to slide in the sliding hole 9.
[0022] An adjustment assembly for adjusting the position of the damper 4 is installed on the side wall of the fixed base 5 facing the housing 1. The adjustment assembly includes an adjustment knob 10, a threaded rod 11, and a slide rod 12. A threaded hole 13 is opened on the side wall of the housing 1. The threaded rod 11 passes through the threaded hole 13 and is threadedly connected to it. The adjustment knob 10 is fixedly set at the end of the threaded rod 11 away from the fixed base 5. The end of the threaded rod 11 away from the adjustment knob 10 is rotatably connected to the side wall of the slide rod 12. Therefore, the rotation of the threaded rod 11 will not conflict with the slide rod 12. Moreover, as the threaded rod 11 extends or shortens from the housing 1, it will also drive the slide rod 12 to slide in the sliding hole 9. The two ends of the slide rod 12 are slidably connected to the inner walls of the sliding holes 9 on the side walls of the two supports 8, respectively. The slide rod 12 is cylindrical. The width of the sliding hole 9 is the same as the diameter of the slide rod 12. The length of the slide rod 12 is greater than the distance between the two supports 8.
[0023] After prolonged use, the buffer pad 6, which is in direct contact with the damper 3, will inevitably deform. In order to ensure the buffering effect of the buffer pad 6, it is necessary to change the part of the buffer pad 6 that is in direct contact with the damper 3. The operator can rotate the adjusting knob 10 so that the threaded rod 11 is screwed into or out of the housing 1 along the threaded hole 13, thereby causing the slide rod 12 to move in the slide hole 9, which in turn drives the fixed seat 5 and the damper 4 to rotate around the rotating seat 7, so that the buffer pad 6 on the top of the damper 4 can buffer the damper 3 from different angles.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
