Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to a novel HVAC air outlet structure. Background Art

[0002] HVAC refers to heating, ventilation and air conditioning, which is widely used, especially in automotive air conditioning. It can provide a comfortable riding environment for passengers and reduce travel fatigue. HVAC mainly realizes the conversion of various modes by controlling the opening angle of the mode damper through the motor.

[0003] The air outlets of existing automobile air conditioners are divided into defrost air outlets, face air outlets, and foot air outlets according to functional requirements. The face air outlet is an integrated structure, and the air outlet direction is a single z-direction. In the overall vehicle layout, the air outlet needs to be assembled with the adapter air duct to achieve the conduction and distribution of the air volume. Since the air outlet direction of the passenger compartment face air duct is x-direction, the front face adapter air duct needs to have a transition structure from z-direction to x-direction. This transition structure occupies a larger z-direction layout space and increases the cost of the adapter air duct. Therefore, further improvement can be made. Utility Model Content

[0004] To solve the above-mentioned problems, the utility model provides the following technical solutions: a novel HVAC air outlet structure, including an air-conditioning case, wherein the air-conditioning case has different air outlets, specifically side-blowing air outlets and front-blowing air outlets, wherein two front-blowing air outlets are split, a filter box is provided on the outside of the front-blowing air outlet, an embedding groove is provided inside the filter box, a filter assembly is provided in the embedding groove, and convenient disassembly and assembly components are provided at both sides of the filter box corresponding to the filter assembly.

[0005] As an optimization, a sleeve plate is fixedly installed on the back of the filter box, and the sleeve plate is cut into several pieces, which can be conveniently deformed and fastened to the outside of the air outlet on the front blowing surface through the cut sleeve plate.

[0006] As an optimization, the filter assembly includes a mounting ring inserted in the embedding groove, a filter screen is arranged inside the mounting ring, a top frame is fixedly installed on the outside of the mounting ring, and card holes are opened on both sides of the mounting ring. The air entering the vehicle is filtered through the filter screen to improve the air quality in the vehicle.

[0007] As an optimization, the filter box is provided with a sliding hole and an active chamber at the clamping hole, and the active chamber is connected to the sliding hole, and the convenient disassembly and assembly component is located in the sliding hole and the active chamber.

[0008] As an optimization, the convenient disassembly and assembly component includes a card column slidingly connected in the sliding hole, a positioning ring is fixedly installed at the end of the sliding hole, a sliding rod is fixedly installed in the middle of the card column, a pull handle is fixedly installed at the other end of the sliding rod, a compression spring is fixedly installed between the card column and the positioning ring, a connecting plate is fixedly installed on the bottom side of the card column, a rotating plate is rotatably connected to the bottom of the connecting plate, and a rotating shaft is rotatably connected to the bending part of the rotating plate.

[0009] As an optimization, the sliding rod is slidably inserted in the positioning ring, and the compression spring is sleeved on the outside of the sliding rod. The positioning ring limits the sliding rod, and the compression spring itself gives the card column a thrust to insert into the card hole, thereby limiting the installation ring.

[0010] As an optimization, a slide groove is opened in the middle of the rotating plate, and the rotating shaft is located in the slide groove and fixedly installed in the movable chamber. By pulling the handle outward, the rotating plate can be driven to deflect through the clamping column, which will squeeze the installation ring to move upward, thereby facilitating the removal of the installation ring.

[0011] Beneficial effects of the utility model: the new HVAC air outlet structure can save a lot of space through the split air outlet structure, and thus does not need to compress and occupy the z-direction space of the air conditioning box assembly, preventing the problem that the air volume and performance required by the air conditioning box cannot be achieved due to the limitation of the boundary of the whole vehicle layout when the air conditioning box is arranged in the whole vehicle, affecting the comfort. The split design can also make the arrangement of the air outlet more flexible, simplify the structure of the transfer air duct, and reduce the overall manufacturing cost. The new HVAC air outlet structure will filter the air entering the car through the filter to improve the air quality in the car, and pulling the handles on both sides will drive the clamping column to be pulled out of the clamping hole, and then the installation ring will no longer be limited. At the same time, the connecting plate will drive the rotating plate to rotate with the rotating shaft as the axis, which will squeeze the installation ring so that the installation ring is pushed upward, thereby facilitating the removal of the filter for cleaning or replacement.
