Description

Technical Field

[0001] This utility model belongs to the field of automotive air conditioning technology, specifically relating to a double-layer sealed automotive air conditioning hybrid damper anti-frost heat insulation component. Background Technology

[0002] The automotive air conditioning hybrid damper anti-frost insulation component is a key functional unit in the air conditioning system responsible for precisely regulating the supply air temperature, preventing frost on the windows, and reducing heat loss. It mainly includes: a hybrid damper actuator, which drives the damper blades by a motor to dynamically adjust the airflow ratio introduced from the evaporator (cold source) and the heater core (heat source) to achieve precise control of the supply air temperature.

[0003] In the prior art, the anti-frost and heat insulation of the automotive air conditioning mixing damper are usually achieved by controlling the output of cold and warm air through the automotive air conditioning mixing damper, thereby preventing frost from forming inside the mixing damper. When performing heat insulation, a heat insulation coating is usually applied inside the mixing damper to prevent heat transfer between cold and warm air, which would affect the output of cold and warm air.

[0004] In existing technologies, most methods control the motor's operation through sensors, which in turn controls the opening size of the damper. However, since most existing technologies use a single-layer sealed structure, it is not possible to accurately control the ratio of hot and cold air output when controlling the airflow ratio. Therefore, we propose a double-layer sealed automotive air conditioning hybrid damper anti-frost and heat insulation component to solve the aforementioned problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7 This utility model provides a double-layer sealed automotive air conditioning mixing damper anti-frost heat insulation component, including a mixing damper component 1, on which an A sealing component 2 and a B sealing component 3 are provided, and the A sealing component 2 and the B sealing component 3 are used in conjunction with the mixing damper component 1 respectively.

[0029] The mixing damper assembly 1 includes a connecting cover 12, which is provided with two air ducts and is separated by a partition. A sleeve rod 19 is rotatably passed through the partition. Two A motors 13 are provided on the connecting cover 12. Control plates 18 are provided at both ends of the sleeve rod 19 and are connected to the output ends of the A motors 13. An air outlet ring 17 is provided at the port of each of the two air ducts.

[0030] A sealing assembly 2 includes A sealing plate 21 and rotating shaft 22. The rotating shaft 22 is disposed on the air outlet ring 17, and the A sealing plate 21 is disposed on the rotating shaft 22.

[0031] Specifically, when directing the airflow of hot and cold air, the connecting cover 12 can be placed at the air outlet of the car's air conditioning system. By connecting the two air ducts to the hot and cold air outlets respectively, hot and cold air can be directed out of the two air ducts. In use, two A motors 13 can be connected to two control boards 18 respectively, and the two control boards 18 can be fitted onto both ends of the sleeve rod 19. At this time, by starting the A motors 13, the control boards 18 can be deflected, thereby opening the air ducts and allowing the hot and cold air to be directed out. In use, By controlling the deflection angle of the output end of motor A 13, the deflection angle of control board 18 can be controlled, thereby controlling the opening size of the air duct, the airflow ratio, and the temperature inside the vehicle. In use, a rotating shaft 22 can be rotated on the air outlet ring 17, and an A sealing plate 21 can be fixed on the rotating shaft 22. At this time, the opening size of the A sealing plate 21 can be controlled to control the proportion of the outgoing airflow. Through the cooperation of the A sealing assembly 2 and the mixing damper assembly 1, the temperature inside the vehicle can be precisely controlled.

[0032] In this embodiment, the hybrid damper assembly 1 further includes a sealing cover 11, which is disposed on the connecting cover 12. The connecting cover 12 is provided with two fixing members 15. The connecting cover 12 is provided with an extension member 14 and two guide members 16, which are respectively disposed at the ports of the two air ducts.

[0033] Specifically, in order to close the air duct during use and prevent leakage of hot or cold air from the connection gap between the sealing cover 11 and the connecting cover 12 when the air is being discharged, a sealing ring can be installed between the sealing cover 11 and the connecting cover 12. In order to ensure that the connecting cover 12 can be stably installed at the air conditioner outlet, a fixing member 15 is installed on the connecting cover 12. By using two fixing members 15 and bolts together, the connecting cover 12 can be stably installed. In order to guide the airflow during use, a guide member 16 can be installed at the air outlet of the air duct to guide the airflow.

[0034] In this embodiment, the A sealing assembly 2 further includes an A mounting member 23, a hinge shaft 24, and a B mounting member 25. The A mounting member 23 is disposed on the control plate 18, the B mounting member 25 is disposed on the A sealing plate 21, and the hinge shaft 24 is hinged to the A mounting member 23 and the B mounting member 25 respectively.

[0035] Specifically, when controlling the deflection of sealing plate A 21, mounting component B 25 can be fixedly installed on sealing plate A 21, and mounting component A 23 can be fixedly installed on control plate 18. The hinge shaft 24 is respectively hinged to mounting component A 23 and mounting component B 25, so that when control plate 18 deflects forward, sealing plate A 21 can deflect forward along with it, thereby opening the air duct, and conversely, closing the air duct.

[0036] In this embodiment, the sealing cover 11 is provided with a blocking plate A 26 and a blocking plate B 27, which are respectively located behind and in front of the control plate 18.

[0037] Specifically, in order to prevent the control plate 18 from deflecting excessively when closing the air duct, which would prevent the air duct from closing and sealing, an A baffle plate 26 and a B baffle plate 27 can be installed on the sealing cover 11. Since the B baffle plate 27 is located below and in front of the control plate 18, while the A baffle plate 26 is located above and in rear of the control plate 18, the control plate 18 can only deflect forward. When it is necessary to close the air duct, the control plate 18 can be rotated. After the control plate 18 contacts the A baffle plate 26 and the B baffle plate 27 respectively, the air duct is in a closed state.

[0038] In this embodiment, the B sealing assembly 3 includes a B sealing plate 34, an A extension 35, and a B extension 36. The A extension 35 is disposed inside the extension 14, and the B extension 36 is disposed on the A extension 35. The surfaces of both the A extension 35 and the B extension 36 are provided with moving grooves, and the B sealing plate 34 is disposed in the moving grooves. The B sealing assembly 3 also includes a gear 32 and a rack 33. The gear 32 is disposed on the A extension 35, and the rack 33 is disposed on the B sealing plate 34. The gear 32 and the rack 33 mesh.

[0039] Specifically, to further control the ratio of hot and cold air flow, extension A 35 and extension B 36 can be provided on extension 14. Sealing plate B 34 is slidably positioned within the moving groove, and a rack 33 is provided on sealing plate B 34. A gear 32 is rotatably mounted on extension A 35, meshing with the rack 33. By controlling the rotation of gear 32, the movement of sealing plate B 34 can be controlled. The movement of sealing plate B 34 within the moving groove allows for different degrees of opening of the air inlets of the hot and cold air ducts. For example, when only cold air needs to enter, the gear 32 can be rotated, causing sealing plate B 34 to move and close the warm air duct inlet. When both hot and cold air need to be introduced into the car, sealing plate B 34 can be positioned between the two ducts. Figure 6 As shown.

[0040] In this embodiment, a B motor 31 is provided on the connecting cover 12. The output end of the B motor 31 is connected to the gear 32. Two rubber seals 37 are provided inside the extension 14, and the two rubber seals 37 are arranged symmetrically.

[0041] Specifically, during use, the rotation of gear 32 can be controlled by starting motor B 31, and rubber seals 37 are installed inside the two air ducts respectively, so that when it is necessary to close a single air duct, the air duct can be closed by contacting the sealing plate B 34 and the rubber seals 37.

[0042] The working principle and usage of this utility model are as follows: When introducing hot and cold air into the car interior, in order to accurately control the proportion of the introduced airflow and thus accurately control the temperature inside the car, an A sealing component 2 and a B sealing component 3 are provided on the mixing damper assembly 1. Through the cooperation of the A sealing component 2 and the B sealing component 3, the mixing damper assembly 1 can accurately export hot and cold air. Furthermore, through the linkage between the A sealing component 2 and the mixing damper assembly 1, the A sealing component 2 can be driven when the mixing damper assembly 1 is driven, thereby enabling the rapid closing and opening of the air duct.

[0043] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
