Description

Technical Field

[0001] The invention relates to the technical field of automobile interior decoration parts, and in particular to a hidden defrosting system. Background Art

[0002] When a car is driving in a cold environment, the windshield is prone to frost due to the temperature difference between the inside and outside of the car, which in turn affects the driver's driving vision, affects driving safety, and even causes major traffic hazards. In order to solve the problem of frosting on the front windshield of a car, a defrosting structure for frosting on the front windshield is installed on the instrument panel near the front windshield in existing vehicles. By connecting with the air supply channel, warm air is blown out from the defrosting air outlet and blown to the front windshield to melt the frost on the glass surface.

[0003] The Chinese utility model patent with publication number CN205930140U and name "Defrost Air Outlet" discloses a defrost air outlet having an air outlet portion pivotally connected to the dashboard of a vehicle by a pivot shaft and having an air outlet facing the front windshield, and a driving mechanism disposed on the vehicle to form a driving connection with the air outlet portion, wherein the air outlet portion has a reciprocating swing relative to the dashboard with the pivot shaft as an axis due to the drive of the driving mechanism. The defrost air outlet described in the utility model drives the air outlet portion to swing back and forth by the driving mechanism, and during defrosting, the reciprocating swing of the air outlet portion can be used to directly blow air to defrost various areas on the front windshield, thereby improving the defrosting efficiency. Moreover, since the air outlet portion and the dashboard are pivotally connected, a larger rotation angle can be achieved, which can also solve the problem of dead angles when blowing air, and can ensure the defrosting effect.

[0004] In the prior art, these air outlets are flush with the instrument panel, which divides the layout of the entire instrument panel, affects the visual effect of the instrument panel, and reduces customer experience. At the same time, the air outlets are designed to be small and the defrosting range is limited. Usually, hot air is provided locally to allow the glass to conduct heat itself to complete defrosting, and the defrosting efficiency is low. Dust in the air duct is easily hung on the air outlet after being blown out, affecting the appearance. The most important thing is that the air outlet is set in a position where direct sunlight is exposed, the parts age quickly, and the air blown out of the air outlet is easy to have an odor. Small objects such as coins can easily fall directly into the air outlet, which may distract the driver's attention during driving. In an environment with sufficient sunlight or dark optical fiber at night, the defrost air outlet may reflect the optical fiber or create a shadow, affecting the driver's line of sight and observation of important information such as the instrument panel, and there are certain hidden dangers. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hidden defrosting system with high defrosting efficiency, beautiful appearance and good visual effect.

[0006] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a hidden defrost system, including an instrument panel body, a defrost cover is arranged along one end of the instrument panel body close to the front windshield, a defrost working part is sunken at the end of the defrost cover close to the front windshield, there is a height difference H between the plane where the defrost working part is located and the plane where the instrument panel body is located, an air outlet connected to an air inlet channel is continuously arranged on the defrost working part, and there is a ratio of 60 to 1 between the setting length of the air outlet and the setting width of the air outlet, the long strip-shaped air outlet can directly bring wind to the working surface of the front windshield, there is no need to complete defrosting through heat conduction, and the defrost efficiency is higher.

[0007] In the above technical solution, the defrost cover plate and the defrost working part form an integrated structure through the air guide surface, and the angle between the air guide surface and the plane where the defrost cover plate is located is β.

[0008] In the above technical solution, a guide structure is protrudingly provided on the defrosting working part located on the side of the air outlet close to the front windshield.

[0009] In the above technical solution, the guide structure is arranged parallel to the wind guide surface, and includes a plurality of guide plates arranged at intervals and protruding from the plane where the defrosting working part is located, which can guide the wind coming out of the air outlet to smoothly reach the front windshield.

[0010] In the above technical solution, the interval between two adjacent guide plates is not less than one third of the setting height of the guide plates.

[0011] In the above technical solution, the arrangement length of the guide structure corresponds to the arrangement length of the air outlet.

[0012] In the above technical solution, the air outlet is an integrated structure, and a number of convex ribs are arranged along the length direction of the air outlet. Due to the long strip arrangement of the air outlet, the provision of a number of convex ribs can help support the air outlet from deformation.

[0013] In the above technical solution, a plurality of air guiding structures are arranged between the air outlet and the air inlet channel.

[0014] In the above technical solution, the air guide structure is integrally arranged on the shell at the air outlet end of the air inlet channel.

[0015] Compared with the prior art, the present invention has the following beneficial effects: through such a hidden design, the defrost air outlet is set under the black border, which can better utilize the structural characteristics of the front windshield to guide the airflow; by reasonably designing the position and shape of the air outlet, the defrost airflow can cover the defrost area of ​​the glass more evenly, thereby improving the defrost efficiency, avoiding uneven distribution of the airflow on the glass, and reducing the residual local fog; making the airflow smoother when passing through the air outlet, reducing the wind resistance and noise caused by air flow turbulence; not being easily invaded by dust, debris, etc.; because it is hidden under the black border and cannot be seen, these visual interferences will not be generated, which helps the driver to concentrate more on driving and improves driving safety; freeing up the space above the dashboard, making the design of the dashboard more flexible.

[0022] The present invention is further described in detail below with reference to the accompanying drawings.

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be used for other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0024] Those skilled in the art should understand that, in the disclosure of the present invention, the directions or positions indicated by the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0025] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0026] See also Figures 1 to 5 A hidden defrost system comprises an instrument panel body 1, a defrost cover 3 is arranged along one end of the instrument panel body 1 close to the front windshield 2, a defrost working part is arranged in a sunken manner close to the front windshield on the defrost cover 3, the defrost working part is a platform structure, there is a height difference H between the plane where the defrost working part is located and the plane where the instrument panel body is located, the setting parameter of the height difference H depends on the angle α between the windshield 2 and the horizontal plane, the height difference H is greater than or equal to sinα, usually, the angle design of α is related to the layout of the car, the angle value set for SUV is greater than the angle value set for sedan and greater than the angle value set for sports car, the value range is about 20°~45°, and the height difference H is adaptively adjusted as the value range changes.

[0027] The defrost cover 3 and the defrost working part form an integrated structure through the air guide surface 32, and the angle between the air guide surface 32 and the plane where the defrost cover 3 is located is β, and the value range of the angle β is between α and 2α, of course, also including two endpoint values.

[0028] The defrosting working part is continuously provided with an air outlet 31 interconnected with the air inlet channel 4, that is, the air outlet 31 is arranged in a long strip shape, and the ratio between the setting length of the air outlet 31 and the setting width of the air outlet is maintained at 60:1.

[0029] Since the air outlet 31 is designed to be long and narrow compared to the traditional small air outlet, in order to ensure the design strength of the air outlet 31, a number of ribs 311 are arranged in the length direction of the air outlet. The ribs 311 are connected across the width direction of the air outlet 31 to ensure that the air outlet 31 is not deformed.

[0030] In order to ensure smooth air guidance, a guide structure 33 is protrudingly provided on the defrosting working part located on the side of the air outlet 31 close to the front windshield 2. The setting height of the guide structure 33 is less than the height difference H. The guide structure 33 is arranged parallel to the air guide surface 32, and includes a plurality of guide plates arranged at intervals and protruding from the plane where the defrosting working part is located. The interval between two adjacent guide plates is not less than one third of the setting height of the guide plates. The arrangement length of the guide structure 33 corresponds to the arrangement length of the air outlet 31.

[0031] In order to ensure that the wind delivered from the air inlet channel 4 smoothly reaches the air outlet 31 and then reaches the front windshield 2, a plurality of air guide structures 41 are arranged between the air outlet 31 and the air inlet channel 4. The air guide structure 41 is integrally arranged on the shell located at the air outlet end 40 of the air inlet channel. The air guide structure 41 is a plurality of raised rib structures, so that the wind can reach the air outlet 31 along the guide channel formed by the ribs according to the predetermined route.

[0032] The working principle of the above technical solution is: the warm air delivered through the air inlet channel 4 enters the air outlet 31 under the guidance of the air guide structure 41, and then defrosts the front windshield 2 under the guidance of the guide structure 33. Since the air outlet is designed to be long and narrow, the defrosting effect can be achieved the moment the warm air reaches the front windshield 2, which is efficient and fast.

[0033] This setting avoids distracting the driver: the existing technology may distract the driver during driving. In sunny or dark environments at night, the defrost vents may reflect the optical fiber or create shadows, affecting the driver's line of sight and observation of important information such as the dashboard. The fully hidden air outlets are invisible under the black border and will not cause these visual distractions, which helps the driver to focus more on driving and improve driving safety; optimize the air flow distribution, set the defrost vents under the black border to better utilize the structural characteristics of the front windshield to guide the air flow, and by reasonably designing the position and shape of the vents, the defrost air flow can be more evenly covered in the defrosting area of ​​the glass, improving the defrosting efficiency. Compared with the air vents set directly above, this design can avoid uneven distribution of air flow on the glass and reduce local residual fog; reduce wind resistance and noise; the design of the fully hidden defrost air vents can better match the black edge structure of the front windshield, making the air flow smoother when passing through the air vents, reducing the wind resistance and noise caused by air flow turbulence, which not only helps to improve the vehicle's economy, but also creates a quieter and more comfortable driving environment in the car; better dust protection, not easy to be invaded by dust, debris, etc., can play a shielding role to a certain extent, reduce the possibility of external dust entering the air vents, thereby reducing the risk of air vent blockage and failure caused by dust accumulation, and extending the service life of the defrost system; enhance waterproof performance, in rainy weather, due to its low position and being blocked by the black edge, it can effectively prevent water from directly entering the air vents, prevent electrical failures and reduced defrosting effects caused by water ingress, improve the reliability and stability of the defrost system, and save space above the dashboard. The defrost air vents directly above usually take up a certain amount of space, which may affect the layout of other parts above the dashboard. The fully hidden defrost vents utilize the space under the black border, freeing up the space above the dashboard, making the dashboard design more flexible and providing more possibilities for the layout of other functional components (such as audio, display, storage box, etc.).

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
