Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning components technology, and in particular to a sliding plate type air conditioning damper mechanism and vehicle. Background Technology

[0002] Automotive air conditioning is a device used to regulate the temperature, humidity, air cleanliness, and airflow inside a car. It aims to provide a comfortable riding environment for passengers, reduce travel fatigue, and create good working conditions for the driver, playing an important role in driving safety. Automotive air conditioning generally consists of a compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed control, and control system.

[0003] In automotive air conditioning systems, the damper is a key component that controls the direction and flow of air. The damper mainly consists of a motor driver, a linkage mechanism, and rotatable or sliding damper blades. When the air outlet mode on the air conditioning panel is adjusted, the damper actuator receives a signal, causing the blades to change position, thereby precisely controlling the airflow path.

[0004] Traditional automotive air conditioning damper mechanisms use gears to rotate an integrated damper plate, controlling the opening and closing of the damper and its angle. The disadvantages include: first, the damper is large, requiring the space of a large cylinder; second, the lever arm is long, and the force on the edge of the damper at the far end is much less than that at the near end, resulting in the damper not closing tightly; and third, the single damper plate has no air guiding structure, leading to uneven temperature when blowing air through the window and onto the face. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a skateboard-type air conditioning damper mechanism and vehicle, which aims to solve the problem that the current dampers are large and require the space of a large cylinder.

[0006] This utility model provides a sliding plate type air conditioning damper mechanism, which is installed inside a vehicle air conditioning unit. The vehicle air conditioning unit includes an air conditioning duct assembly and an air outlet opened on the air conditioning duct assembly. The sliding plate type air conditioning damper mechanism is movably installed inside the air conditioning duct assembly and is located near the air outlet. The sliding plate type air conditioning damper mechanism includes a damper assembly.

[0007] The damper assembly includes at least two damper components movably disposed on the air conditioning duct assembly, and a damper drive component for driving the damper components, wherein the damper drive component drives the damper components by means of a linkage.

[0008] The damper component includes a flipping component connected to the output shaft of the damper drive component, and a sliding component movably connected to the flipping component on the side away from the damper drive component and slidably disposed within the air conditioning duct assembly.

[0009] The above-mentioned damper drive component uses a linkage mechanism to drive the damper component to slide along a trajectory, which is the principle of the traditional crank-slider mechanism or cam-connecting rod mechanism. This makes the movement trajectory of the damper component similar to a household door, but modified into a sliding door. When applied to the air conditioning unit of an automobile, the damper folds, increasing the cross-sectional area of ​​the ventilation duct, saving internal space, and solving the problem that the current dampers are too large and require the space of a large cylinder.

[0010] In addition, the sliding plate type air conditioning damper mechanism proposed according to the embodiments of this utility model may also have the following additional technical features:

[0011] Furthermore, the air conditioning duct assembly has a groove for accommodating the sliding member at the connection point of the damper, so that when the sliding member rotates with the flipping member, the side away from the flipping member is restricted from sliding by the groove trajectory.

[0012] Furthermore, the flipping component includes a linkage shaft axially connected to the damper drive component, a first damper plate and a second damper plate extending outward along both radial sides of the linkage shaft, and a movable shaft disposed on the side of the second damper plate away from the linkage shaft.

[0013] Furthermore, the sliding member includes a sliding damper plate that is flipped and connected to the second damper plate via the movable shaft, and a sliding shaft disposed on the side of the sliding damper plate away from the movable shaft. The sliding shaft is embedded in the groove and slides along the groove trajectory.

[0014] Furthermore, the second damper plate is also equipped with an air guide plate for concentrating air.

[0015] Furthermore, the damper drive component includes a drive shaft, a linkage cam, and a drive unit that are sequentially connected to the linkage shaft.

[0016] In addition, this application also provides a vehicle, including a skateboard-type air conditioning damper mechanism disposed on the vehicle. Attached Figure Description

[0027] Please see Figures 1 to 4 The image shows a sliding plate-type air conditioning damper mechanism in an embodiment of this utility model. It is installed inside a vehicle air conditioning system. The vehicle air conditioning system includes an air conditioning duct assembly 1 and an air outlet 3 opened on the air conditioning duct assembly 1. The sliding plate-type air conditioning damper mechanism is movably installed inside the air conditioning duct assembly 1 and is located near the air outlet 3. The sliding plate-type air conditioning damper mechanism includes a damper assembly 2. The damper assembly includes at least two damper components 22 movably installed on the air conditioning duct assembly 1 and a damper drive component 21 for driving the damper components 22. The damper component 22 includes a flipping component connected to the output shaft of the damper drive component 21 and a sliding component movably connected to the side of the flipping component away from the damper drive component 21 and slidably installed inside the air conditioning duct assembly 1.

[0028] Furthermore, the air conditioning duct assembly 1 has a groove 11 for accommodating the sliding member at the connection of the damper member 22, so that when the sliding member follows the flipping member to flip, the side away from the flipping member is restricted to slide by the groove track 11. The flipping member includes a linkage shaft 221 axially connected to the damper drive member 21, a first damper plate 222 and a second damper plate 223 extending outward on both sides of the linkage shaft 221 radially, and a movable shaft 223 disposed on the side of the second damper plate 223 away from the linkage shaft 221. 4. The sliding component includes a sliding damper plate 225 that is flipped and connected to the second damper plate 223 via a movable shaft 224, and a sliding shaft 226 disposed on the side of the sliding damper plate 225 away from the movable shaft 224. The sliding shaft 226 is embedded in the slide groove 11 and slides along the track of the slide groove 11. The second damper plate 223 is also provided with a wind guide plate 227 for concentrating air. The damper drive component 21 includes a drive shaft 211, a linkage cam 212, and a drive part 213 that are sequentially connected to the linkage shaft 221.

[0029] In practice, the operator can first control the vehicle's air conditioning to be turned on through the air conditioning ECU. The air conditioning ECU is the core controller of the vehicle's air conditioning control system. It is responsible for receiving signals from various sensors (such as temperature sensors, pressure sensors, etc.) and controlling various components of the air conditioning system, such as the compressor electromagnetic clutch, cooling fan, blower, etc., based on these signals. The air conditioning ECU analyzes sensor data to automatically adjust the operating status of the air conditioning system to achieve stable and comfortable temperature inside the vehicle. During the operation of the air conditioning ECU by the operator, the damper assembly 2 is activated and performs damper control adjustment. Specifically, when the damper drive component 21 receives a control signal, the drive unit 213 is activated. In some optional embodiments, the drive unit 213 can be a motor. Then, the drive unit 213 sequentially drives the linkage cam 212 and the drive shaft 211 to rotate the linkage shaft 221. The rotation trajectories of the linkage cam 212 and the drive shaft 211 are both eccentrically designed, so that the axial driving force of the drive unit 213 is applied eccentrically to the linkage shaft 221. This causes the second damper plate 223 connected to the linkage shaft 221 to move along a sliding trajectory, which is the principle of a traditional crank-slider mechanism or cam-connecting rod mechanism. It can be understood as similar to a house door being replaced with a sliding door, applied to the automotive air conditioning unit, allowing the damper to fold, increasing the cross-sectional area of ​​the ventilation duct, saving internal space, and avoiding the traditional air... The door occupies a large amount of space when it is axially rotated. Furthermore, to ensure a better fit between the sliding path of the sliding damper 225 and the opening of the air outlet 3 during the aforementioned process, a groove 11 is added to the air conditioning duct assembly 1 to accommodate the sliding shaft 226 on the sliding damper 225. This restricts the movement path of the sliding damper 225, while the opening of the air outlet 3 can be set according to the path of the groove 11, improving the fit between the opening and the sliding damper 225. Additionally, during the sliding of the sliding shaft 226 along the trajectory of the groove 11… The groove 11 can cooperate with the sliding shaft 226 to provide good structural support based on the bottom of the sliding damper plate 225. While ensuring that the sliding damper plate 225 is fully adapted to the opening of the air outlet 3, it also ensures the stability of the sliding damper plate 225 after sliding adjustment. In addition, in some optional embodiments of this utility model, the damper plate structure of this application can also be made of PP material with secondary injection molding and rubber coating (SEBS) process on its edges. The rubber is semi-enclosed with an inner hollow design so that when the damper is closed, the rubber and the shell have a certain amount of compression, so that the damper fits tightly.

[0030] In summary, by using the damper drive component 21, the damper component 22 is driven to move along a sliding trajectory by a linkage mechanism, which is the principle of a traditional crank-slider mechanism or cam-connecting rod mechanism. This makes the movement trajectory of the damper component 22 similar to a household door, but modified into a sliding door. When applied to the air conditioning unit of an automobile, the damper folds, increasing the cross-sectional area of ​​the ventilation duct, saving internal space, and solving the problem that the current dampers are too large and require the space of a large cylinder.
