Description

Technical Field

[0001] This invention relates to the construction of a defrosting mechanism for vehicles. Background Technology

[0002] To prevent fogging and other issues on the windshield panel, vehicles have a defroster that blows air in a predetermined direction toward the passenger compartment side surface of the windshield panel. For example, Patent Document 1 describes a defrosting air outlet disposed along the lower edge of the windshield panel on the upper surface of the dashboard.

[0003] On the other hand, in recent years, the number of electrical components installed inside the dashboard has increased, requiring more space to accommodate them. If the defrost air vents could be positioned closer to the end of the dashboard, sufficient space could be secured. Furthermore, the image of the defrost air vents is reflected by the windshield panel and enters the occupant's forward line of sight. If the vents were positioned closer to the front, the image would be closer to the lower edge of the windshield panel, ensuring a wide and clear field of vision. Therefore, considering both the increase in electrical components and ensuring a good view of the landscape, it is desirable to position the defrost air vents at the front.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2012-148668 Summary of the Invention

[0007] When the defrost air outlet is located on the dashboard, a separate defrost air outlet component is usually prepared and fitted into an opening in the dashboard component. The defrost air outlet component is then fixed to the dashboard component using resin clips or similar means. However, considering the strength of the dashboard and the installation strength of the defrost air outlet component, a structure is often adopted where the defrost air outlet component is surrounded and fixed by the dashboard component. Therefore, for example... Figure 5 As shown, a front portion 200A of the instrument panel component 200 is also required on the front side of the defrost blowout component 300, so that the measures for placing the defrost air outlet in the front position are limited.

[0008] The present invention was made to solve the above-mentioned problems and aims to provide a defrosting structure that can ensure the strength of the dashboard and the installation strength of the defrosting air outlet component, while enabling the defrosting air outlet to be positioned in the dashboard close to the windshield panel further forward.

[0009] To address the aforementioned issues, the defrosting structure of the present invention comprises: a windshield panel disposed at the front of the vehicle compartment; an instrument panel extending from the windshield panel toward the rear of the vehicle compartment; an outlet member disposed on the instrument panel and having an opening for blowing defrosting air relative to the windshield panel; and a channel member disposed below the instrument panel and forming a path for supplying the defrosting air to the opening. The outlet member comprises: an adjacent portion forming the leading edge of the opening and adjacent to the windshield panel; and a fixing portion connected to the adjacent portion. In a cross-sectional view in the front-rear direction, the fixing portion is fixed to the channel member at a position further forward than the front end of the windshield panel exposed in the vehicle compartment.

[0010] Invention Effects

[0011] According to the present invention, the strength of the dashboard and the installation strength of the defrost blowout component can be ensured, while the defrost air outlet can be configured in a position close to the windshield panel on the front side of the dashboard.

[0044] Embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, the defrosting structure 1 of this embodiment blows defrosting air from an opening 31 provided in the dashboard 20 to defrost the windshield panel 10. The opening 31 is formed in an outlet component 30, which is a component separate from the dashboard 20 and is disposed in the dashboard 20. The defrosting air is supplied through a path formed by the channel component 40. Furthermore, Figure 2 This is a top view showing a portion of the defrosting structure 1 of the embodiment, namely the instrument panel 20 and the blow-out component 30.

[0045] Figure 1 The magnified view shows the front part of defrosting structure 1, which is... Figure 2 A cross-sectional view at line I-I.

[0046] (Windshield panel)

[0047] The windshield panel 10 is a panel-shaped component of the window located in front of the vehicle compartment 80. The windshield panel 10 is inclined and lowered towards the front. In addition, the windshield panel 10 is curved in a convex shape along the width of the vehicle.

[0048] The side 11 of the windshield panel 10 on the vehicle compartment 80 side is bounded by the front end 12, and the upper portion of it is exposed within the vehicle compartment 80 compared to the front end 12. The position of the front end 12 is the position of the upper end of the sealing member 13 in the side 11. The sealing member 13 is a component disposed in the gap between the windshield panel 10 and the component on the vehicle compartment 80 side, and is made of, for example, polyurethane foam. Figure 1 In the middle, the windshield panel 10 and the air outlet component 30 (described later) sandwich the sealing component 13 adjacent to each other. Above the sealing component 13 in the side 11, a portion of a ceramic strip 14 coated with black ceramic or the like is exposed inside the vehicle compartment 80. The portion of the ceramic strip 14 exposed inside the vehicle compartment 80 is located in the lower area, within the range of the left and right ends of the windshield panel 10. The front end 12 is located in front of the upper end of the ceramic strip 14.

[0049] The windshield panel 10 is supported by the windshield panel support member 15, which will be described later, at a position lower than the front end 12, that is, at a position not exposed inside the vehicle compartment 80.

[0050] (Dashboard)

[0051] The dashboard 20 is a component that forms the front wall of the passenger compartment 80. The dashboard 20 extends from the windshield panel 10 toward the rear of the passenger compartment 80. Below the dashboard 20, the passage component 40 (described later) and electrical components are arranged.

[0052] like Figure 1 As shown, the instrument panel 20 has a sloping surface that rises forward and a sloping surface that descends forward from the upper end of the rising sloping surface, forming a mountain shape with a apex 22 in the cross-section. By setting it to a mountain shape, the air outlet component 30 can be positioned in a location that is difficult for the occupant to see.

[0053] like Figure 2As shown, when viewing the instrument panel 20 from the upper surface, the air outlet component 30 is configured such that the opening 31 is located inside the mounting portion 23, which is configured such that its front end is cut out in a roughly trapezoidal shape. Here, the front end of the instrument panel 20 and the front end of the air outlet component 30 are connected in a forward-protruding curved manner. On the left and right sides of the air outlet component 30, the front end of the instrument panel 20 is adjacent to the windshield panel 10. Therefore, the sealing component 13 is disposed in the gap between the windshield panel 10 and the instrument panel 20 or the air outlet component 30 from the left end to the right end of the vehicle compartment 80. Alternatively, the front end of the instrument panel 20 and the front end of the air outlet component 30 may be connected in a straight line.

[0054] (Channel component)

[0055] The channel component 40 is a component that forms a path for supplying defrosting air. The channel component 40 has an air guide portion 41 that serves as a path for the defrosting air and is disposed below the instrument panel 20. The air guide portion 41 of the channel component 40 is connected to the air outlet component 30. An extension portion 43 extending forward is provided on the front wall 42 located at the front end side of the air guide portion 41.

[0056] (Blowout outlet component)

[0057] The outlet component 30 is a component that forms the outlet for defrosting air. The outlet component 30 has an opening 31, an adjacent portion 32, a fixing portion 33, and a rear edge portion 36. For example... Figure 2 As shown, the fixing part 33 has multiple (four) on the front side.

[0058] Opening 31 is an opening for defrosting air to be blown out. Here, as... Figure 1 As shown, the opening 31 faces slightly rearward compared to the top and is provided with a cover 31A. The cover 31A is, for example, a grid-shaped component.

[0059] The adjacent portion 32 forms the leading edge of the opening 31 and is adjacent to the windshield panel 10 at the front end. Here, the adjacent portion 32 forms an inclined surface that slopes forward from the leading edge of the opening 31, bends at the lower end of the inclined surface and extends forward, and abuts against the sealing member 13 at the front end.

[0060] The fixing part 33 is formed by connecting to the front end side of the adjacent part 32. In the longitudinal section of the longitudinal direction of the vehicle width direction at each position of the fixing part 33, it is fixed to the passage member 40 at a position further forward than the front end 12 of the windshield panel 10. In addition, in the longitudinal section of the longitudinal direction of the longitudinal direction of the vehicle width direction at each position of the fixing part 33, it is fixed to the passage member 40 at a position further forward than the upper end of the ceramic strip 14.

[0061] like Figure 2As shown, when viewed from above, three of the four fixing parts 33 are fixed to the channel member 40 at a position forward of the frontmost end 21 of the instrument panel 20. It is sufficient that at least a portion of the plurality of fixing parts 33 are fixed to the channel member 40 at a position forward of the frontmost end 21 of the instrument panel 20.

[0062] The fixing part 33 has a protrusion 35 that protrudes forward compared to the adjacent part 32. Here, the fixing part 33 has a hanging part 34 that is a wall surface hanging down from the front end side of the adjacent part 32, and the protrusion 35 is formed in such a way that it extends forward from the lower end side of the hanging part 34.

[0063] The fixing parts 33, located near the left and right ends and near the center of the blow-out component 30, ensure the stable fixation of the blow-out component 30. Here, one fixing part 33 (protrusion 35) is provided near each of the left and right ends, and two more near the center, for a total of four fixing parts 33 (protrusions 35). The protrusions 35 near the center are wider in the left-right direction to further improve stability. The protrusions 35 are fixed to the upper surface of the extension 43 by vibration welding. Alternatively, fixation can be achieved using clips, claws, screws, adhesives, etc.

[0064] like Figure 1 As shown, the rear edge portion 36 forms the rear edge of the opening 31 and an inclined surface rising rearward from the rear edge. The peripheral portion of the rear edge portion 36 is configured to overlap with the instrument panel 20 from above. The rear edge portion 36 is connected to the adjacent portion 32 via a side edge portion. The side edge portion forms the side edge of the opening 31, and the peripheral portion of the side edge portion is also configured to overlap with the instrument panel 20 from above, just like the rear edge portion 36.

[0065] Figure 3A This is a perspective view showing the removal of the blow-out nozzle component 30. Based on the fixing of the fixing part 33 to the channel part 40, the blow-out nozzle component 30 can be further fixed to the side edge or rear edge of the opening 31 to the instrument panel 20. By further fixing it to the instrument panel 20, the rigidity of the front end of the instrument panel 20 can be improved. Fixing can be performed using clips, claws, screws, adhesives, etc. For clip fixing, for example... Figure 3B As shown, a clip insertion hole 24 is provided in the mounting part 23 of the instrument panel 20, and the insertion part provided in the blow-out part 30 is inserted therein, thereby securing it.

[0066] For example, when using a clamp for fixation, after the instrument panel 20 with the outlet component 30 clamped and fixed thereon is installed on the channel component 40, the protrusion 35 and the extension 43 can be fixed by vibration welding or the like. Alternatively, after the instrument panel 20 is installed on the channel component 40, the outlet component 30 can be clamped and fixed to the instrument panel 20, and the protrusion 35 and the extension 43 can be fixed by vibration welding or the like. Furthermore, the outlet component 30 can also be fixed solely by the protrusion 35 (fixing part 33).

[0067] (Windshield panel support components)

[0068] like Figure 1 As shown, the windshield panel support member 15 is a member that supports the windshield panel 10 from the rear side at a position that is forward and lower than the adjacent portion 32. The windshield panel support member 15 supports the lower part and extends upward at a position not shown, and supports the windshield panel 10 near the upper end 15A via the abutment member 16.

[0069] The windshield panel support member 15 is bent forward in a convex shape, surrounding the front side of the extension 43 and the protrusion 35, with the upper end 15A located above the protrusion 35.

[0070] (Isolation components)

[0071] The insulating component 50 is a sheet-like component installed between the engine compartment and the passenger compartment 80 at the front of the vehicle for the purpose of soundproofing and vibration damping.

[0072] The isolation component 50 is located below the instrument panel 20, and is installed below the channel component 40 and the outlet component 30. Figure 4 This is a view of the installed insulating component 50 from the lower surface side. (See diagram.) Figure 4 As shown, the isolation member 50 has a locking hole 51, which is supported by hooking onto the protrusion 35 fixed to the extension 43.

[0073] The defrosting structure 1 of the present invention is basically constructed as described above, and the effects of the defrosting structure 1 will be explained next.

[0074] The defrosting structure 1 of the present invention includes: a windshield panel 10 disposed in front of the vehicle compartment 80; an instrument panel 20 extending from the windshield panel 10 toward the rear of the vehicle compartment 80; an outlet member 30 disposed on the instrument panel 20 and having an opening 31 for blowing defrosting air relative to the windshield panel 10; and a channel member 40 disposed below the instrument panel 20 and forming a path for supplying defrosting air to the opening 31. The outlet member 30 has: an adjacent portion 32 that forms the leading edge of the opening 31 and is adjacent to the windshield panel 10; and a fixing portion 33 connected to the adjacent portion 32. When viewed in cross-section in the front-rear direction, the fixing portion 33 is fixed to the channel member 40 at a position further forward than the front end of the windshield panel 10 exposed in the vehicle compartment 80.

[0075] According to this configuration, by placing the air outlet member 30, which has an opening 31 for blowing defrosting air relative to the windshield panel 10, on the instrument panel 20, the periphery of the opening 31 can be made into a part different from that of the instrument panel 20, thereby facilitating the adjustment of the shape of the opening 31, etc. Furthermore, the air outlet member 30 has: an adjacent portion 32 that forms the leading edge of the opening 31 and is adjacent to the windshield panel 10; and a fixing portion 33 connected to the adjacent portion 32. When viewed in cross-section in the front-rear direction, the fixing portion 33 is fixed to the passage member 40 at a position further forward than the front end of the windshield panel 10 exposed in the vehicle compartment 80. This allows the air outlet member 30 to be located at a position close to the windshield panel 10 on the front side of the instrument panel 20, thereby ensuring a complete space below the instrument panel 20 and behind the air outlet member 30. In addition, the image of the air vent component 30, especially the image of the opening 31, which is reflected by the windshield panel 10 and enters the occupant's field of vision, is located at the lower edge of the windshield panel 10 in the vehicle compartment 80, thus ensuring good visibility and improving the view while driving.

[0076] Furthermore, by fixing the fixing part 33 to the channel member 40 disposed below the instrument panel 20, the blow-out part 30 having the opening part 31 can be directly fixed to the channel member 40, thereby stabilizing the positional relationship between the blow-out part 30 and the channel member 40.

[0077] The defrosting structure 1 of the present invention includes: a windshield panel 10 disposed in front of the vehicle compartment 80; an instrument panel 20 extending from the windshield panel 10 toward the rear of the vehicle compartment 80; an outlet member 30 disposed on the instrument panel 20 and having an opening 31 for blowing defrosting air relative to the windshield panel 10; and a channel member 40 disposed below the instrument panel 20 and forming a path for supplying defrosting air to the opening 31. The outlet member 30 has: an adjacent portion 32 that forms the leading edge of the opening 31 and is adjacent to the windshield panel 10; and a fixing portion 33 connected to the adjacent portion 32. At least a portion of the fixing portion 33 is fixed to the channel member 40 at a position further forward than the foremost end 21 of the instrument panel 20.

[0078] According to this configuration, by placing the air outlet member 30, which has an opening 31 for blowing defrost air relative to the windshield panel 10, on the instrument panel 20, the periphery of the opening 31 can be made into a part different from that of the instrument panel 20, thereby facilitating the adjustment of the shape of the opening 31, etc. Furthermore, the air outlet member 30 has: an adjacent portion 32 that forms the leading edge of the opening 31 and is adjacent to the windshield panel 10; and a fixing portion 33 connected to the adjacent portion 32. At least a portion of the fixing portion 33 is fixed to the channel member 40 at a position further forward than the foremost end 21 of the instrument panel 20, thereby allowing the air outlet member 30 to be located at a position close to the windshield panel 10 on the front side of the instrument panel 20, thus ensuring a complete space below the instrument panel 20 and behind the air outlet member 30. In addition, the image of the air vent component 30, especially the image of the opening 31, which is reflected by the windshield panel 10 and enters the occupant's field of vision, is located at the lower edge of the windshield panel 10 in the vehicle compartment 80, thus ensuring good visibility and improving the view while driving.

[0079] By fixing the fixing part 33 to the channel member 40 disposed below the instrument panel 20, the blow-out part 30 having the opening part 31 can be directly fixed to the channel member 40, thereby stabilizing the positional relationship between the blow-out part 30 and the channel member 40.

[0080] Preferably, in the defrosting structure 1 of the present invention, the fixing part 33 is fixed to the channel component 40 by vibration welding.

[0081] According to this configuration, by vibration welding, the volume of the fixing part 33 can be reduced compared to the case of screw fixing, thereby suppressing interference with other components and ensuring the fixed position of the fixing part 33 efficiently.

[0082] The defrosting structure 1 of the present invention is preferably such that the fixing part 33 has a protrusion 35 that protrudes forward compared to the adjacent part 32.

[0083] According to this configuration, the fixing part 33 has a protrusion 35 that protrudes forward compared to the adjacent part 32, thereby ensuring the fixed position of the fixing part 33 stably compared to the adjacent part 32.

[0084] The defrosting structure 1 of the present invention preferably further includes a windshield panel support member 15 that supports the windshield panel 10 in front of and below the adjacent portion 32, with the upper end 15A of the windshield panel support member 15 located above the protrusion 35.

[0085] With this configuration, the upper end 15A of the windshield panel support member 15 is located above the protrusion 35. This allows for effective utilization of the space below the upper end 15A to accommodate the protrusion 35, eliminating the need to change the position of the fulcrum of the windshield panel 10 based on the windshield panel support member 15. Therefore, the stability of the support provided by the windshield panel support member 15 can be maintained, while ensuring the fixed position of the protrusion 35.

[0086] The defrosting structure 1 of the present invention preferably further includes an isolation member 50 installed below the channel member 40 and the blowout member 30, at least a portion of the isolation member 50 being hooked and supported by the protrusion 35.

[0087] According to this configuration, at least a portion of the insulating member 50 is hooked and supported by the protrusion 35, thereby eliminating the need for a special shape for mounting the insulating member 50, and enabling the reduction of components and space saving.

[0088] The defrosting structure 1 of the present invention preferably has a fixing part 33 having a hanging part 34 hanging down from the adjacent part 32 and a protrusion 35 extending forward from the lower end side of the hanging part 34, and a channel member 40 having a front wall 42 provided on the front end side of the channel member 40 and an extension part 43 extending forward from the front wall 42, and the protrusion 35 being fixed to the upper surface of the extension part 43.

[0089] According to this configuration, the fixing part 33 has a hanging portion 34 extending from the adjacent part 32 and a protrusion 35 extending forward from the lower end side of the hanging portion 34, thereby allowing adjustment of the height of the protrusion 35. Furthermore, the channel member 40 has a front wall 42 located at the front end side of the channel member 40 and an extension portion 43 extending forward from the front wall 42. The protrusion 35 is fixed to the upper surface of the extension portion 43, thereby allowing the extension portion 43 to be positioned in accordance with the protrusion 35, thus fixing the protrusion 35. Therefore, the space below the upper end 15A of the windshield panel support member 15 can be utilized more effectively to position the protrusion 35 and ensure a fixed position.

[0090] The defrosting structure 1 of this embodiment has been described above, but the present invention is not limited to this embodiment and can be appropriately modified within the scope of the present invention without departing from the spirit of the present invention.

[0091] For example, in this embodiment, four fixing parts 33 are described, but the number of fixing parts 33 can be three or less, or five or more. Furthermore, the width of each fixing part 33 can be smaller or larger. The fixing parts 33 can be connected as one along the vehicle width direction. When the width of the fixing part 33 is large, it is sufficient that a portion of it in the vehicle width direction is fixed to the passage member 40 at a position further forward than the foremost end 21 of the instrument panel 20.

[0092] Furthermore, for example, in this embodiment, the case where the front ends of the instrument panel 20 and the air outlet component 30 are bent is described, but the front ends of the instrument panel 20 and the air outlet component 30 may also be connected in a straight line. In this case, the entire fixing part 33 is fixed to the channel component 40 at a position further forward than the foremost end 21 of the instrument panel 20.
