Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard technology, specifically to a sealing structure for a front defrosting air duct of a dashboard. Background Technology

[0002] The defrosting duct in front of the car dashboard is an important component of the car's air conditioning system. It is mainly used to eliminate fog and frost on frozen items inside the car. It mainly includes forced exhaust ducts and fishtail ducts. Dust can easily enter the defrosting duct during the defrosting process, affecting its use.

[0003] According to Chinese Patent Publication No. CN203344692U, "A Defrosting Structure for a Car Instrument Panel," the main description involves disassembling the instrument panel body into two parts: a base plate and a panel. An auxiliary air duct is formed between the base plate and the panel, which is connected to the main air duct and extends to the front windshield of the car. This allows heat from the car's engine compartment to be directed and blown towards the windshield, greatly accelerating the warming and defrosting of the windshield and ensuring the normal operation of the wipers. However, during this process, when the defrosting air duct is not in use, dust can easily enter the vehicle's interior and accumulate within it. When the hot air in the air duct comes into contact with the interior environment, moisture is easily generated, causing the dust entering the air duct to become damp and sticky, thus blocking the air duct.

[0004] Therefore, a sealing structure for the defrosting duct in front of the dashboard is proposed to solve the problem that dust easily enters the vehicle interior when the defrosting duct is not in use and accumulates in the duct. When the hot air in the duct comes into contact with the vehicle interior environment, moisture is easily generated, causing the dust entering the duct to become damp and sticky, thus causing the duct to become blocked. Utility Model Content

[0005] The technical problem to be solved by this utility model is that dust can easily enter the air duct, causing blockage. Therefore, a sealing structure for the defrosting air duct in front of the dashboard is proposed.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a sealing structure for a defrosting air duct in front of an instrument panel, including a main air duct, a main air outlet fixedly connected to one side of the main air duct, a groove opened at the upper end of the main air outlet, and positioning rods threadedly connected to both sides of the main air outlet at the groove, a connecting plate sleeved on the positioning rod, a support plate integrally formed by casting on the connecting plate, a pad contacting the bottom side of the support plate, the pad contacting the upper side of the main air outlet, a filter frame fixedly connected to the bottom end of the support plate, a drive motor fixedly connected to one side of the filter frame, and a screw fixedly connected to the output end of the drive motor, an auxiliary rod provided on the upper side of the screw and fixedly connected inside the filter frame, a scraper threadedly connected to the screw, and brushes evenly fixedly connected to the outer side of the scraper, with the brushes in contact with the filter frame.

[0007] As a preferred technical solution of this utility model, a collection frame is in contact with one side of the filter frame, and a groove is provided on the bottom side of the collection frame and the groove corresponds to the screw. By setting the collection frame, dust can be collected.

[0008] As a preferred technical solution of this utility model, a toothed bar is uniformly fixedly connected to one side of the collection frame. The toothed bar corresponds to the brush on the outside of the scraper. By setting the toothed bar, the pressure when the brush enters is small and the pressure when it leaves is large, which can comb the brush.

[0009] As a preferred technical solution of this utility model, a guide block is integrally formed on one side of the collection frame by casting. The guide block has a triangular structure. By setting the guide block, the rebound resistance can be reduced and the dust accumulation can be reduced.

[0010] As a preferred technical solution of this utility model, spring pins are inserted into both sides of the collection frame. The spring pins are located on one side of the filter frame. By setting the spring pins, the collection frame can be limited and can be easily disassembled.

[0011] This utility model has the following advantages: by installing a detachable support plate and filter frame inside the main air outlet of the main air duct, and by using a screw to drive the scraper and brush to move and clean the filter frame, a protective structure can be set up at the main air duct, thereby preventing dust from entering the main air duct, forming a sealed structure, and collecting the dust, which is convenient for collection and treatment.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to Figure 1-4 The instrument panel front defrost air duct sealing structure shown includes a main air duct 1, a main air outlet 2 fixedly connected to one side of the main air duct 1, a groove opened at the upper end of the main air outlet 2, and positioning rods 3 threadedly connected to both sides of the main air outlet 2. A connecting plate 4 is sleeved on the positioning rod 3, and the positioning rod 3 connects with the main air outlet 2 to fix a support plate 5 and a pad 14. The connecting plate 4 is integrally formed by casting with the support plate 5. The bottom side of the support plate 5 contacts the pad 14, and the pad 14 contacts the upper side of the main air outlet 2. The bottom end of the support plate 5 is fixed. A filter frame 6 is fixedly connected to the filter frame 6 to prevent dust from entering the main air outlet 2. A drive motor 7 is fixedly connected to one side of the filter frame 6, and a screw 8 is fixedly connected to the output end of the drive motor 7. An auxiliary rod is provided on the upper side of the screw 8 and is fixedly connected inside the filter frame 6. A scraper 9 is threadedly connected to the screw 8, and brushes are evenly fixedly connected to the outer side of the scraper 9. When the drive motor 7 starts, it drives the screw 8 to rotate. Under the limit of the auxiliary rod, the scraper 9 and the brushes move linearly and clean the surface of the filter frame 6, and the brushes contact the filter frame 6.

[0019] The screw 8 corresponds to the groove, which is located on the bottom side of the collection frame 10. The collection frame 10 is in contact with the filter frame 6. By setting the collection frame 10, the scraper 9 and the brush can enter the collection frame 10 to clean the dust.

[0020] Among them, the brush on the outside of the scraper 9 corresponds to the toothed slats 11. The toothed slats 11 are evenly fixedly connected to one side of the collection frame 10. The toothed slats 11 are set at an angle. When the brush moves into the collection frame 10, the pressure of the brush entering the collection frame 10 is small. Then, when the brush moves away from the collection frame 10, the pressure of moving out is large, which will cause the dust adhering to the brush to detach and remain in the collection frame 10, making it easy to clean.

[0021] The guide block 12 is integrally formed with the collection frame 10 by casting. The guide block 12 has a triangular structure. By setting the guide block 12, the brush can be guided.

[0022] Among them, a spring pin 13 is inserted into one side of the filter frame 6. The spring pin 13 is located on both sides of the collection frame 10. By setting the spring pin 13, the collection frame 10 can be fixed in the filter frame 6, and the collection frame 10 can be removed by pulling.

[0023] Working principle: A main air outlet 2 is opened on one side of the main air duct 1 for ventilation. Then, a support plate 5 and a filter frame 6 are installed on the upper side of the main air outlet 2 to provide dust protection and prevent dust and moisture from sticking to the inside of the main air duct 1, forming a theoretically sealed structure and improving the performance of the main air duct 1. In daily use, the drive motor 7 is started to drive the screw 8 to rotate. Under the action of the auxiliary rod, the scraper 9 and the brush move and clean the inside of the filter frame 6 to prevent dust accumulation from causing poor airflow from the main air outlet 2. The dust is also guided into the collection frame 10. The collection frame 10 is then installed on one side of the filter frame 6 and works with the toothed scraper 11 to clean the dust stuck to the brush. The collection frame 10 can be detached by pulling the spring pin 13.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
