Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, and in particular relates to an air intake cover, a front door, and a vehicle. Background Technology

[0002] In some vehicle models (such as buses, trucks, vans, MPVs, or some mid-to-large SUVs), the driver's and passenger's side windows are relatively large, while the distance between the air conditioning vents on the side of the dashboard and the corresponding side window is also large. In this case, the airflow cannot completely cover the window glass, and when the window glass fogs up, the defogging effect is poor, which affects the driver's ability to observe the road conditions to the side and rear of the vehicle through the window and rearview mirror. Especially when the vehicle needs to change lanes, the driver cannot accurately judge whether the road conditions to the side and rear are suitable for a safe lane change, which will affect driving safety. Document CN208198038U "Window Glass Defrost Device and Vehicle Having It" discloses the installation of air ducts in the door to independently blow air onto the window for defrosting (the principle of defrosting and defogging is similar), but it does not disclose the specific structure of the air intake of the air duct on the door. However, the door and the dashboard are separate structures, so how to ensure that the air ducts are connected and reduce airflow loss when they are closed is particularly important. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, one of the objectives of this utility model is to provide an air inlet cover that has both protective and sealing functions.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: an air inlet sleeve includes a rigid grille and a flexible protective ring. The flexible protective ring is annular and surrounds the periphery of one side of the rigid grille. The rigid grille has a plurality of elastic hooks spaced circumferentially on the side opposite to the flexible protective ring, and the hook openings of the elastic hooks are opposite to the center of the rigid grille.

[0011] The beneficial effect of the above technical solution is that it makes the flexible retaining ring have better extrusion deformation characteristics, thereby making its sealing effect better.

[0012] The second objective of this utility model is to provide a car door with an independent air duct that can blow air and defog the car window glass.

[0013] To achieve the above objectives, another technical solution of this utility model is as follows: A front door includes a door body, a first ventilation pipe, and an air inlet sleeve as described above. The door body has an inner panel, and the window edge of the inner panel has a first air outlet. The front end of the inner panel is provided with a first air inlet on the side corresponding to the interior of the vehicle. The first ventilation pipe is disposed in the door body, and the two ends of the first ventilation pipe are respectively connected to the first air inlet and the first air outlet. The air inlet sleeve is fastened to the first air inlet by a plurality of elastic hooks, and the flexible protective ring protrudes outside the inner panel.

[0014] The beneficial effects of the above technical solution are as follows: by setting an air inlet sleeve at the first air inlet, foreign objects can be prevented from entering the first air duct, and the flexible protective ring can improve the sealing characteristics at the first air inlet.

[0015] In the above technical solution, the first air outlet is located at the front end of the window sill, and the first air outlet is a terrain outlet distributed in the front-to-back direction.

[0016] The beneficial effect of the above technical solution is that it enables the first air outlet to blow air and defog a wide area in front of the car window.

[0017] In the above technical solution, a guide grille is provided at the first air outlet. The guide grille is used to direct the airflow blown out of the first air outlet to the rear and upward and deflect it toward the car window glass.

[0018] The beneficial effects of the above technical solution are: it allows the airflow discharged from the first air outlet to better defog the car window glass, while the air guide grille can prevent foreign objects from entering the first air duct.

[0019] The air guide grille described in the above technical solution has multiple horizontal and vertical air guide strips arranged in a crisscross pattern. The multiple horizontal air guide strips are arranged vertically in the left-right direction and spaced apart in the front-back direction. The multiple vertical air guide strips are arranged vertically in the front-back direction and spaced apart in the left-right direction. The upper end of the horizontal air guide strips is inclined towards the rear and upward to guide the airflow to the rear and upward. The upper end of the vertical air guide strips is inclined towards the vehicle window to guide the airflow to the vehicle window glass.

[0020] The beneficial effect of the above technical solution is that it enables the longitudinal and transverse air guides to work together to direct the airflow to the upper rear and deflect it toward the car window glass.

[0021] The third objective of this utility model is to provide a vehicle that can independently blow air and defrost the front windows.

[0022] To achieve the above objectives, another technical solution of this utility model is as follows: A vehicle includes an instrument panel and a front door as described above. A second air outlet is provided at the end of the instrument panel, and a second air duct is provided inside the front side of the instrument panel. One end of the second air duct is connected to and communicates with the second air outlet, and the other end of the second air duct is used to communicate with an air conditioning duct. When the front door is closed, the first air inlet and the second air outlet are aligned and communicate with each other. The flexible protective ring is used to seal the edge at the connection between the first air inlet and the second air outlet.

[0023] The beneficial effect of the above technical solution is that it allows the flexible guard to better seal between the first air inlet and the second air outlet when the car door is closed.

[0024] In the above technical solution, a protective grille is provided at the second air outlet.

[0025] The beneficial effect of the above technical solution is that it can prevent foreign objects from entering the second air duct. Attached Figure Description

[0044] like Figures 1-3 as well as Figure 6 and Figure 8As shown, this embodiment provides a vehicle including a front door 1 and an instrument panel 2. The front door 1 includes a door body 12, a first ventilation duct 13, an air intake sleeve 11, and a window glass 14. The door body 12 has an inner panel 121, and the window edge of the inner panel 121 has a first air outlet 122. The front end of the inner panel 121 is provided with a first air inlet 123 on the side corresponding to the interior of the vehicle. The first ventilation duct 13 is disposed inside the door body 12, and both ends of the first ventilation duct 13 are respectively connected to the first air inlet 123 and the first air outlet 122. The air intake sleeve 11 is disposed at the first air inlet 123. The instrument panel 2 is provided with... There is a second air outlet 21. A second air duct 22 is provided inside the front side of the instrument panel 2. One end of the second air duct 22 is connected to and connected to the second air outlet 21. The other end of the second air duct 22 is used to connect to the air conditioning duct (which is an existing configuration of the vehicle and will not be described in detail here). When the front door 1 is closed, the inner panel 121 and the end of the instrument panel 2 are fitted together. The first air inlet 123 is aligned with and connected to the second air outlet 21. The air inlet sleeve 11 is used to seal the edge of the connection between the first air inlet 123 and the second air outlet 21, so as to prevent air leakage at the connection between the first air inlet 123 and the second air outlet 21.

[0045] The vehicle described in this embodiment can be a bus, truck, van, MPV, or mid-to-large SUV. Of course, it is also possible that it can be a sedan or a small or medium-sized SUV (commercial vehicles are preferred).

[0046] The front door 1 provided in this embodiment is similar to the door structure disclosed in document CN208198038U "Window Defrosting Device and Vehicle Having the Same". The advantage of this embodiment is that an air inlet sleeve 11 is added at the first air inlet 123 (of course, in this embodiment, an air volume adjustment mechanism as described in the above document can also be set at the first ventilation pipe 13).

[0047] Specifically, such as Figures 3-5 As shown, the air inlet sleeve 11 includes a rigid grille 111 and a flexible protective ring 112. The flexible protective ring 112 is annular and surrounds the periphery of one side of the rigid grille 111. The rigid grille 111 has a plurality of elastic hooks 113 spaced circumferentially on the side opposite to the flexible protective ring 112. The hook openings of the elastic hooks 113 are opposite to the center of the rigid grille 111. The air inlet sleeve 11 is fastened to the first air inlet 123 by the plurality of elastic hooks 113, and the flexible protective ring 112 protrudes outside the inner protective plate 121.

[0048] Preferred, such as Figure 7As shown, the outer edge of the rigid grille 111 near the flexible guard ring 112 is turned outward to form an abutment ring 1111, and the flexible guard ring 112 is disposed on the abutment ring 1111.

[0049] like Figure 6 and Figure 7 As shown, in this embodiment, when the air inlet sleeve 11 is installed at the first air inlet 123, the rigid grille 111 with the elastic hook 113 on one side is inserted into the first air inlet 123, while the abutment ring 1111 abuts against the outer side of the inner guard plate 121, and multiple elastic hooks 113 are fastened to the inner side of the inner guard plate 121 (the inner side of the inner guard plate 121 is the side near the first ventilation pipe 13, and the outer side of the inner guard plate 121 is the side near the instrument panel 2), thereby realizing the detachable installation of the air inlet sleeve 11 at the first air inlet 123 (for the rigid grille 111, one side has an abutment ring 1111, and the other side has an elastic hook 113, so that the rigid grille 111 can be embedded in the first air inlet 123 and is not easy to loosen).

[0050] The rigid grille 111 mainly serves a protective function, preventing foreign objects from entering the first air duct through the first air inlet 123; the flexible protective ring 112 mainly serves a sealing function, and it has a certain elasticity and good deformation characteristics.

[0051] In this embodiment, the vehicle can have both the driver's side door and the passenger side door using the front door 1 of this embodiment, so that both the driver's side door and the passenger side door have independent defogging ducts.

[0052] The principle of this embodiment is as follows: taking the driver's door as an example, the driver's door has a defogging channel composed of a first air outlet 122, a first air duct and a first air inlet 123, while the instrument panel 2 has a second air outlet 21, and the second air outlet 21 is connected to the air conditioning duct through the second air duct 22.

[0053] When the driver's side door is opened, the defrosting channel on the driver's side door separates from and disconnects from the second air outlet 21. At this time, the defrosting channel of the driver's side door does not have a defrosting function.

[0054] When the driver's side door is closed, the inner panel 121 of the driver's side door is partially fitted with the side of the instrument panel 2 (with a gap between them), and the first air inlet 123 is aligned and connected with the second air outlet 21 (there is a possibility of air leakage through the gap at the connection). In order to prevent air leakage, an air inlet sleeve 11 is provided at the first air inlet 123 to seal the edge between the first air inlet 123 and the second air outlet 21. This achieves a sealed connection between the first air inlet 123 and the second air outlet 21 without affecting the normal opening or closing of the driver's side door.

[0055] The passenger side door is similar to the driver's side door, so it will not be described in detail here.

[0056] like Figure 6 As shown, in this embodiment, the air intake cover 11 is detachably installed at the first air intake 123, which makes it easy to replace the air intake cover 11. In particular, the flexible protective ring 112 has a certain service life, and it may age and crack after a long period of use. Once the flexible protective ring 112 is damaged, there may be air leakage at the connection between the first air intake 123 and the second air outlet 21 when the front door 1 is closed. Therefore, the air intake cover 11 needs to be replaced in time.

[0057] In this embodiment, the flexible retaining ring 112 is made of rubber, and the rigid grid 111 is made of plastic, with the flexible retaining ring 112 and the rigid grid 111 integrally formed. This makes it less likely for the flexible retaining ring 112 to detach from the rigid grid 111.

[0058] In this embodiment, the material of the elastic hook 113 is the same as that of the rigid grid 111, and it is preferable that the two are integrally formed. Specifically, the material of the elastic hook 113 and the rigid grid 111 (rigid but somewhat tough plastic) can be polypropylene or polyamide, but it is not limited to these.

[0059] Preferably, the inner side of the flexible retaining ring 112 has an annular groove (e.g., Figure 7 As shown, the flexible retaining ring has a "C"-shaped cross-section (with its opening located inside the ring) or an annular cavity inside (i.e., the cross-section of the flexible retaining ring is "O"-shaped). Specifically, the flexible retaining ring is similar to the rubber edging strip used at the edge of a car door. This gives the flexible retaining ring 112 better extrusion deformation characteristics, resulting in a better sealing effect.

[0060] like Figure 1 , Figure 6 and Figure 8As shown, in this embodiment, the first air outlet 122 is located at the front end of the window sill, and the first air outlet 122 is a strip-shaped opening distributed in the front-back direction. This allows the first air outlet 122 to blow air and defog a wide area of ​​the front part of the vehicle window glass 14.

[0061] like Figure 12 As shown, since the first air outlet 122 has a certain length, the end of the first ventilation duct 13 that connects to the first air outlet 122 can be extended backward to widen. However, in order to ensure that the airflow at each point at the end of the first ventilation duct 13 that connects to the first air outlet 122 is relatively uniform, it is necessary to provide at least one diversion ridge 131 in the first ventilation duct 13 near the end of the first air outlet 122. The function of the diversion ridge is equivalent to dividing the end of the first ventilation duct that connects to the first air outlet into multiple sub-channels 132 in the front-back direction. This can prevent the airflow from concentrating at the front end of the first air outlet 122 for discharge. Figure 12 As shown in the example, it has a branching ridge 131, thus branching into two sub-channels 132, and Figure 12 The two dashed arrows in the middle represent a schematic diagram of airflow flowing out through the two sub-channels 132.

[0062] Preferred, such as Figure 6 As shown, in this embodiment, an air guide grille 124 is provided at the first air outlet 122. The air guide grille 124 is used to guide the airflow blown out of the first air outlet 122 to the upper rear and deflect it toward the window glass 14. This allows the airflow discharged from the first air outlet 122 to better defog the window glass 14, while the air guide grille 124 can prevent foreign objects from entering the first air duct.

[0063] In this embodiment, both the air guide grille 124 and the inner protective plate 121 are plastic parts, and they are integrally formed, which makes the structure at the first air outlet 122 more aesthetically pleasing.

[0064] Further preferred, such as Figures 9-11 As shown, the air guide grille 124 has a square structure. The air guide grille 124 contains multiple horizontal air guide strips 1241 and vertical air guide strips 1242 arranged in a crisscross pattern. The horizontal air guide strips 1241 are vertically arranged in the left-right direction and spaced apart in the front-back direction. The vertical air guide strips 1242 are vertically arranged in the front-back direction and spaced apart in the left-right direction. The upper ends of the horizontal air guide strips 1241 are inclined upwards and backwards to guide the airflow upwards and backwards. The upper ends of the vertical air guide strips 1242 are inclined towards the window glass 14 to guide the airflow towards the window glass 14. This allows the vertical air guide strips 1242 and the horizontal air guide strips 1241 to work together to guide the airflow from the first air outlet 122 upwards and backwards, deflecting it towards the window glass 14.

[0065] Further preferred, such as Figure 10 and Figure 11 As shown, the tilt angles of the multiple horizontal air guides 1241 relative to the vertical plane are different. Specifically, in the direction from back to front, the tilt angles of the multiple horizontal air guides 1241 gradually decrease (e.g., Figure 10 (where α1 > α2), and the tilt angles of the multiple longitudinal air guides 1242 relative to the vertical plane are also different. Specifically, in the direction relative to the window glass 14 from near to far, the tilt angles of the multiple longitudinal air guides 1242 gradually decrease (e.g., ...). Figure 11 (β1 > β2). This allows the airflow from the first air outlet 122 to more efficiently defog the window glass 14. Specifically, the tilt angle of the horizontal air guide strip 1241 and the vertical air guide strip 1242 should be selected within the range of 30°-80°. The specific angle value needs to be determined according to factors such as the size of the glass area and the length of the first air outlet, which will not be elaborated here.

[0066] In this embodiment, both the first ventilation pipe 13 and the second ventilation pipe can be metal pipes or plastic pipes. Preferably, both the first ventilation pipe 13 and the second ventilation pipe can be flat pipes, which makes it more convenient to install the first ventilation pipe 13 inside the front door 1 and the second ventilation pipe in front of the dashboard 2.

[0067] like Figure 2 As shown, in this embodiment, a protective grille 23 is provided at the second air outlet 21 to prevent foreign objects from entering the second ventilation duct. Preferably, the protective grille 23 and the instrument panel 2 are both plastic parts and are integrally formed, which makes the structure of the second air outlet 21 more aesthetically pleasing.

[0068] In this embodiment, the grille holes of the protective grille 23 and the rigid grille 111 are perpendicular to the mating surface of the inner guard plate 121 and the instrument panel 2 (the protective grille 23 and the rigid grille 111 are similar to grille plates, with multiple through grille holes in the middle for airflow to pass through). This makes the airflow smoother at the connection between the first air inlet 123 and the second air outlet 21, and the flow resistance is small (the airflow does not need to be guided when passing through this point).

[0069] Preferably, the first air inlet 123 and the second air outlet 21 are both approximately square or round holes, and the shapes of the air inlet sleeve 11 and the protective grille 23 are matched accordingly.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
